EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
1 Year

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 250% of the average value of its portfolio.
Principal investment strategies
The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies, including, but not limited to, common stocks and depositary receipts. An issuer is deemed to be economically tied to the United States if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the United States; (ii) a majority of the issuer’s revenues are derived from the United States; or (iii) a majority of the issuer’s assets are located in the United States. Under normal circumstances, the Fund seeks to achieve returns with lower volatility over a full market cycle than the Russell 1000® Index (the Fund’s broad-based benchmark index). The Fund seeks to generate such returns with volatility that can range from approximately 0% to 40% lower than the Russell 1000 Index. In this context, volatility refers to the variation in the returns of the Fund and the broad-based benchmark index as measured by the standard deviation of monthly returns. The market capitalization of issuers within the broad-based benchmark index, from which the Fund’s investment universe is derived, will vary, but as of June 30, 2024, it ranged from approximately $170 million to $3.32 trillion.
The Fund pursues its investment objective by applying a proprietary methodology to construct an investment portfolio of equity securities from a universe of the 750 largest U.S. issuers in the Russell 1000 Index by market capitalization whose securities are also characterized by broad options market liquidity. Portfolio management applies a systematic investment process that monitors day-to-day movements in options prices on individual U.S. issuers for indicators of upside (or good) and downside (or bad) volatility to forecast their risk and reward. In applying this investment process, portfolio management seeks to avoid issuers whose upside volatilities are perceived to be lower and whose downside volatilities are perceived to be higher, resulting in a portfolio that is expected to generate returns with lower volatility over a full market cycle. Although the
2 | Janus Henderson Adaptive Risk Managed U.S. Equity Fund

Fund is generally expected to underperform the Russell 1000 Index in sharply rising markets, this strategy seeks to minimize losses in down markets.
The Fund may engage in active and frequent trading to achieve its investment objective.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Industry and Sector Risk.Although the Fund does not concentrate its investments in specific industries, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Companies in the same industry or economic sector may be similarly affected by negative economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may offset gains or increase losses in the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.
Depositary Receipts Risk.Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency.
Volatility Risk.There is no guarantee that the Fund’s strategy to minimize volatility will be successful. Securities in the Fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the Fund’s strategy to minimize volatility could limit the Fund’s gains in rising markets.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on December 22, 2014. The performance shown for Class D Shares for the period July 6, 2009 to December 22, 2014, reflects the performance of the Fund’s Class I Shares, calculated using the fees and expenses of Class D Shares, without the effect of any fee and expense limitations or waivers. Performance shown for periods prior to July 6, 2009, reflects the historical performance of Janus Adviser INTECH Risk-Managed Value Fund’s (the “JAD Predecessor Fund”) Class I Shares prior to the reorganization of Class I Shares of the JAD Predecessor Fund into Class I Shares of the Fund, calculated using the fees and expenses of Class D Shares, without the effect of any fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to December 22, 2014, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 10, 2022, the Fund changed its investment strategy. Performance prior to June 10, 2022 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
The Fund’s broad-based benchmark index is the Russell 1000 Index. The Fund’s additional benchmark is the S&P 500 Minimum Volatility Index. The indices are described below.
The Russell 1000 Index measures the performance of the large-cap segment of the U.S. equity universe.
The S&P 500 Minimum Volatility Index is designed to reflect a managed-volatility equity strategy that seeks to achieve lower total risk, measured by standard deviation, than the S&P 500 while maintaining similar characteristics.
After-tax returns are calculated using distributions for the Fund’s Class D Shares for periods following December 22, 2014; for the Fund’s Class I Shares for the period following July 6, 2009; and for the JAD Predecessor Fund’s Class I Shares for periods prior to July 6, 2009. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
With respect to share classes not offered in this Prospectus, the Fund or its distributor (or its affiliates) pay select broker-dealer firms or other financial intermediaries for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing a broker-dealer or other intermediary or a salesperson to recommend the Fund over another investment or to recommend one share class over another.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services, as well as reimbursement to the Adviser of its out-of-pocket costs for services as administrator. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses”

include acquired fund fees and expenses, which are indirect expenses the Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. Such amounts are less than 0.01%.
°
may include reimbursement to the Transfer Agent of its out-of-pocket costs for arranging for the provision by third parties of certain servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse the Fund’s “Total Annual Fund Operating Expenses” to a certain limit for at least a one-year period commencing on October 28, 2024. The expense limit is described in the “Management Expenses” section of this Prospectus.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, the Fund will provide shareholders with at least 60 days’ notice prior to changing the 80% investment policy. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary section, including the types of securities the Fund may invest in when pursuing its investment objective. This section also describes investment strategies and policies that the Fund may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since the Fund’s composition can change over time. Except for the Fund’s policies with respect to illiquid investments, borrowing, and
7 | Janus Investment Fund

derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if the Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
The Fund’s investment process seeks to achieve returns with lower volatility over a full market cycle than the Russell 1000 Index. The investment process involves selecting stocks from a universe of the 750 largest U.S. issuers in the Russell 1000 Index by market capitalization whose securities are also characterized by broad options market liquidity. Portfolio management applies a systematic investment process that monitors day-to-day movements in options prices on individual U.S. issuers for indicators of upside (or good) and downside (or bad) volatility to forecast their risk and reward. In applying this investment process, portfolio management seeks to avoid issuers whose upside volatilities are perceived to be lower and whose downside volatilities are perceived to be higher, resulting in a portfolio that is expected to generate returns with lower volatility over a full market cycle.
Cash Position
The Fund normally remains as fully invested as possible and does not seek to lessen the effects of a declining market through hedging or temporary defensive positions. The Fund may use futures, options, and other derivatives, to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. There is no guarantee that these types of derivative investments will work and their use could cause lower returns or even losses to the Fund. To the extent the Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
Commercial Paper
The Fund may invest in commercial paper. Commercial paper refers to short-term, unsecured promissory notes issued by banks, corporations and other borrowers to finance short-term credit needs. Commercial paper is usually sold on a discount basis and typically has a maturity at the time of issuance not exceeding nine months. The Fund may invest in investment grade commercial paper (e.g., that is rated Prime-3 or higher by Moody’s Investors Service, Inc. (“Moody’s”) or A-3 or higher by Standard & Poor’s Ratings Services (“S&P”) or, if unrated by Moody’s or S&P, is issued by a company having an outstanding debt issue rated investment grade).
Derivatives
The Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. The Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
Exchange-Traded Funds
The Fund may invest in exchange-traded funds (“ETFs”). ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of the Fund, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. The Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
The Fund may invest in foreign securities. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities.
8 | Janus Investment Fund

Portfolio Turnover
The rebalancing techniques used by the Fund typically result in higher portfolio turnover compared to a “buy and hold” fund strategy. Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on the Fund’s performance. Portfolio turnover rates are not a factor in making buy and sell decisions. The “Financial Highlights” section of this Prospectus shows the Fund’s historical turnover rates.
REITs and Real Estate-Related Securities
The Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Securities Lending
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When the Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, the Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to the Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Other Types of Investments
Unless otherwise stated within its specific investment policies, the Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Fund. If successful, they may benefit the Fund by earning a return on the Fund’s assets or reducing risk; however, they may not achieve the Fund’s investment objective.
Risks of the Fund
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Fund. Because the Fund may invest substantially all of its assets in common stocks, the main risk is the risk that the value of the stocks it holds might decrease in response to the activities of an individual company or in response to general market and/or
9 | Janus Investment Fund

economic conditions. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
Commercial Paper Risk.Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, the Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of swaps, futures, and options). The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.
Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which the Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, the Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because the Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.
10 | Janus Investment Fund

Foreign Exposure Risk.Within the parameters of its specific investment policies, the Fund may invest in foreign equity and debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because the Fund’s performance may depend on factors other than the performance of a particular company. Such risks include currency risk, foreign market risk, geographic concentration risk, political and economic risk, and regulatory risk due to greater exposure to a particular country or geographic region.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of the Fund’s shares. The Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in the Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares.
Market Risk.The value of the Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Money Market Fund Investment Risk.The Fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and the Fund may lose money. To the extent the Fund transacts in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share net asset value at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of
11 | Janus Investment Fund

redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable net asset value could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their net asset values. Certain money market funds have in the past failed to maintain stable net asset values, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the Securities and Exchange Commission (the “SEC”) require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s net asset value per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating net asset value requirements. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund.
Recently adopted amendments to Rule 2a-7 also require certain money market funds, excluding Government Money Market Funds and Retail Money Market Funds, to impose mandatory liquidity fees when a fund experiences net redemptions that exceed 5% of its net assets, unless the fund’s liquidity costs are de minimis (i.e., less than 1 basis point).
There can be no assurance that the Fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market fund in which it invests.
REIT and Real Estate-Related Securities Risk.To the extent the Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which the Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. The Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing the return to the Fund on its investment in such company.
Small- and Mid-Sized Companies Risk.The Fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or
12 | Janus Investment Fund

more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Fund reimburses the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Fund’s Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Fund. The Fund pays these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs expenses, including administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund must pay.
The following table reflects the Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual compensation rate paid by the Fund to the Adviser after any applicable fee waivers and/or expense reimbursements. The rate shown is a fixed rate based on the Fund’s average daily net assets.

A discussion regarding the basis for the Trustees’ approval of the Fund’s investment advisory agreement is included in the Fund’s semiannual report (for the period ended December 31, 2023) and in the Fund’s financial statements (for the period ended June 30, 2024, and moving forward). You can request the Fund’s semiannual reports or financial statements (as they become available), free of charge, by contacting a Janus Henderson representative at 1-800-525-3713. This information is also available, free of charge, at janushenderson.com/reports.
Expense Limitation
The Adviser has contractually agreed to waive the advisory fee payable by the Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed 0.59% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. Prior to June 10, 2024, the Adviser had contractually agreed to waive 0.05% of its advisory fee for a period of two years. For information about how the expense limit (as applicable) affect the total expenses of the Fund, see the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus.
Portfolio management
Janus Henderson Adaptive Risk Managed U.S. Equity Fund
Ashwin Alankar, Ph.D., is Head of Global Asset Allocation of Janus Henderson Investors. He is Executive Vice President and Portfolio Manager of Janus Henderson Adaptive Risk Managed U.S. Equity Fund, which he has managed since June 2022. Mr. Alankar is also Portfolio Manager of other Janus Henderson accounts. He joined the Adviser in 2014. Mr. Alankar holds a Bachelor of Science degree in Mathematics and Chemical Engineering and a Master of Science degree in Chemical Engineering from the Massachusetts Institute of Technology, and a Ph.D. in Finance from the University of California at Berkeley’s Haas School of Business.
Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of his individual ownership in the Fund(s) that he manages, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that the Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.

Other information
CLOSED FUND POLICIES
The Fund may limit sales of its Shares to new investors. If sales of the Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Fund
The Fund is distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well.
How Distributions Affect the Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of the Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in the Fund’s daily net asset value (“NAV”). The share price of the Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, the Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of the Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus Henderson representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
Distribution Options
When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janushenderson.com/individual, by calling a Janus Henderson representative, or by writing to the Fund at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Fund offers the following options:
Reinvestment Option.You may reinvest your income dividends and capital gains distributions in additional shares.
Cash Option.You may receive your income dividends and capital gains distributions in cash.
Reinvest and Cash Option.You may receive either your income dividends or capital gains distributions in cash and reinvest the other in additional shares.
Redirect Option.You may direct your dividends or capital gains distributions to purchase shares of another Janus Henderson fund.
The Fund reserves the right to reinvest uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Shareholder Services and Account Policies.”

TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of the Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, the Fund is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds
18 | Janus Investment Fund

from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, the Janus Henderson funds will report cost basis information to you and to the IRS. The Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s manual
This Shareholder’s Manual is for those shareholders investing directly with the Fund. This section will help you become familiar with the different types of accounts you can establish with the Adviser. It also explains in detail the wide array of services and features you can establish on your account, as well as describes account policies and fees that may apply to your account. Account policies (including fees), services, and features may be modified or discontinued without shareholder approval or prior notice.
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.

All states have repealed UGMA statutes, enacting UTMA statutes in their place. Existing UGMA accounts established before the date of repeal are grandfathered using the original UGMA age of termination.
Minimum Investment Requirements
Due to the proportionately higher costs of maintaining small accounts, the Fund reserves the right to deduct an annual $25 minimum balance fee per Fund account (paid to the Transfer Agent) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You will receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.
Available Incentive Programs
Bonus Program for Taxable Account Purchases and Tax-Advantaged Account Transfers/Rollovers
Through the Transfer Agent’s Bonus Program, the Transfer Agent will pay a bonus of up to $2,500 to you for making certain eligible purchases of Fund shares in taxable accounts or transfers/rollovers from a non-Janus Henderson fund account into a Janus Henderson fund tax-advantaged account. The Bonus Program is valid with an eligible purchase or transfer/rollover of $20,000 or more. If you meet the eligibility requirements for the Bonus Program and enroll in it, the Transfer Agent will deposit a bonus payment into your Fund account within approximately 30 days after the deposit of eligible funds in good order and receipt of a signed contract governing the Bonus Program. An investor must keep the eligible purchase in the account for a period of 360 calendar days in order to retain the bonus payment. Any sale of the qualifying purchase amount (in whole or in part), transfer, or closure of the account within the 360 calendar day period may result in forfeiture of the bonus payment. Any decline in an account’s value due solely to market value fluctuations will not result in the forfeiture of the bonus payment. Only taxable account purchases or transfers/rollovers to tax-advantaged accounts that are made on or after January 1, 2024 through December 31, 2024 are eligible for a bonus payment. The eligible period for the Bonus Program may be extended beyond this time frame at the sole discretion of the Transfer Agent. Before enrolling in the Bonus Program, consult with your tax advisor about the appropriate tax treatment for the bonus offer and any tax implications associated with the receipt of a bonus payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke this Bonus Program at any time without advance notice.
You can request more information about the Transfer Agent’s Bonus Program and eligibility requirements for taxable accounts by contacting a Janus Henderson representative at 1-800-525-3713 or by visiting www.janushenderson.com/bonus. You can request more information about the Bonus Program for tax-advantaged account transfers/rollovers by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Contribution Match Payments
Investors that transfer/rollover assets from a non-Janus Henderson fund account into a tax-advantaged account are also eligible for the Transfer Agent’s Contribution Match Program. To receive a Transfer Agent’s Contribution Match payment, (i) the value of your tax-advantaged account must remain equal to or greater than the value of the eligible transfer/rollover (but not including any losses due solely to market value fluctuations) for 12 months following the receipt of your transfer/rollover in good order and receipt of a signed contract governing the Contribution Match Program, and (ii) you must provide instructions to the Transfer Agent on how to invest these payments. The Transfer Agent’s Contribution Match payments will commence at the end of the first quarter in 2025 following an eligible contribution during the first quarter of 2025 into a Janus Henderson fund tax-advantaged account. The eligible period for the Transfer Agent’s Contribution Match payments may be extended beyond this time frame at the sole discretion of the Transfer Agent. The Transfer Agent will match a percentage of these contributions based on the aggregate value of eligible 2024 rollover or asset transfer amounts, and provide a matching contribution in an amount up to ten percent of your contribution. Before enrolling in the Contribution Match Program, consult with your tax advisor about the appropriate tax treatment for the Transfer Agent’s Contribution Match payments and any tax implications associated with the receipt of a Contribution Match payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Contribution Match Program at any time without advance notice.

Ready. Invest. Go. Program
New investors creating a new Janus Henderson direct account are eligible to participate in the Transfer Agent’s Ready. Invest. Go. Program. After the new investor has completed the required Ready. Invest. Go. Program Contract, the Transfer Agent will fund the $100 initial investment required for new investors, provided that new investors enroll in Janus Henderson’s automatic investment program in an amount equal to at least $50 per month. New investors will forfeit the $100 bonus contributed by the Transfer Agent if their account is closed or if their automatic monthly investment program payment is terminated within two years from the date the initial investment was made. Investor-initiated amounts outside of the initial investment are redeemable at any time at net asset value. Before enrolling in the Ready. Invest. Go. Program, new investors should consult with their tax advisor about the appropriate tax treatment for participating in the Ready. Invest. Go. Program and any tax implications associated with the receipt of the $100 initial investment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Ready. Invest. Go. Program at any time without advance notice.

Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by the Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after your request is received in good order by the Fund or its agents.
24 | Janus Investment Fund

Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of the Fund’s portfolio securities and the reflection of such change in the Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of the Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by the Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used. Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.

Policies in Relation to Transactions
All requests, including but not limited to, exchanges between the Fund and other Janus Henderson funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus Henderson’s P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase.
Administrative services fees
The Fund pays an annual administrative services fee based on the average daily net assets of Class D Shares, as detailed below.
Average Daily Net Assets of Class D Shares of the Janus Henderson funds
Administrative Services Fee
Under $40 billion
0.12%
$40 billion - $49.9 billion
0.10%
Over $49.9 billion
0.08%
These administrative services fees are paid by Class D Shares of the Fund. The Transfer Agent provides or arranges for the provision of shareholder services including, but not limited to, recordkeeping, accounting, answering inquiries regarding accounts, transaction processing, transaction confirmations, and the mailing of prospectuses and shareholder reports.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary and when considering which share class of a fund is most appropriate.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or
26 | Janus Investment Fund

recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you.
Paying for shares
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to buy shares.
Please note the following when purchasing Shares:
Cash, credit cards, third party checks (with certain limited exceptions), travelers cheques, credit card checks, line of credit checks, or money orders will not be accepted.
All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted non-U.S. bank.
Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.
When purchasing Shares through the Automatic Investment Program, your automatic investment selection(s) will generally be active within three days following receipt of your authorization for the date and amount you specify. If no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. If the balance in the Janus Henderson fund account you are buying into falls to zero as the result of a redemption, exchange, or minimum balance fee, your Automatic Investment Program will be discontinued.
We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Fund by submitting good funds via another method accepted by the Fund (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading. For more information about the Fund’s policy on excessive trading, refer to “Excessive Trading.”
If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as applicable, will be invested in Janus Henderson Government Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus Henderson to (i) buy shares of another Janus Henderson fund or (ii) sell shares of Janus Henderson Government Money Market Fund and return the proceeds (including any dividends earned) to you, Janus Henderson will treat your inaction as approval of the purchase of Janus Henderson Government Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus Henderson for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Henderson Government Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Henderson Government Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will be automatically exchanged from Janus Henderson Government Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”
27 | Janus Investment Fund

For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.
If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and any losses incurred by the Fund as a result. The Fund may redeem shares held in your account to cover any losses it incurs if your purchase is cancelled.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), the Adviser is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, the Adviser may temporarily limit additional share purchases. In addition, the Adviser may close an account if it is unable to verify a shareholder’s identity. Please contact a Janus Henderson representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
The Fund has also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Fund is required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.
Exchanges
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Please note the following when exchanging Shares:
An exchange represents the redemption (or sale) of shares from the Fund and the purchase of shares of another fund, which may produce a taxable gain or loss in a non-retirement account.
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. The Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.
New regular Janus Henderson fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus Henderson fund account you are exchanging from is less than $2,500 ($100 for new regular Fund accounts with an automatic investment program of $50 per month). (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus Henderson fund account you are exchanging from is less than the stated minimum, you must exchange the entire
28 | Janus Investment Fund

balance. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
New Janus Henderson fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
Exchanges between existing Janus Henderson fund accounts must meet the $50 subsequent investment requirement.
For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus Henderson fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. The Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. Different restrictions may apply if you invest through an intermediary.
The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
With certain exceptions, exchanges between Janus Henderson fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus Henderson fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.

Payment of redemption proceeds
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.
Next Day Wire Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.
ACH (Automated Clearing House) Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on or about the next bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.
By Check – Redemption proceeds will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.
By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus Henderson fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.
29 | Janus Investment Fund

The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Generally, orders to sell Shares may be initiated at any time at janushenderson.com/individual, by telephone, or in writing. Certain accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Fund can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide alternate instructions, your proceeds will be invested in Shares of Janus Henderson Government Money Market Fund during the 15-day hold period.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. A temporary hold may also be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult has occurred, is occurring, has been attempted, or will be attempted, as described under “Temporary Suspension of Services.”
Note: For the fastest and easiest way to redeem shares, log on to janushenderson.com/individual* 24 hours a day, 7 days a week.

Large Shareholder Redemptions
Certain large shareholders, such as other funds, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time
30 | Janus Investment Fund

and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Written Instructions
To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus Henderson.” Requests or documents received in a language other than English may be inadvertently delayed or returned due to an inability to accurately translate the intended instructions.

the name of the Janus Henderson fund(s) being redeemed or exchanged;
the account number(s);
the amount of money or number of shares being redeemed or exchanged;
the name(s) on the account;
the signature(s) of one or more registered account owners; and
your daytime telephone number.
Signature Guarantee
A signature guarantee for each registered account owner is required if any of the following is applicable:
You request a redemption by check above a certain dollar amount.
You would like a check made payable to anyone other than the shareholder(s) of record.
You would like a check mailed to an address that has been changed within 10 days of the redemption request.
You would like a check mailed to an address other than the address of record.

The Fund reserves the right to require a signature guarantee under other circumstances or to reject or delay a redemption on certain legal grounds.
A signature guarantee may be refused if any of the following is applicable:
It does not appear valid or in good form.
The transaction amount exceeds the surety bond limit of the signature guarantee.
The guarantee stamp has been reported as stolen, missing, or counterfeit.

Call your financial institution to see if it has the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Fund is intended for long-term investment purposes, and the Fund will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Fund’s exchange limits or excessive trading policies and procedures may be cancelled or rescinded by the Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Fund is also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
31 | Janus Investment Fund

The Fund monitors for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Fund at all times reserves the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to the Fund.
The Fund’s Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Fund’s excessive trading policies and procedures and may be rejected in whole or in part by the Fund. Transactions accepted by a financial intermediary in violation of the Fund’s excessive trading policies may be cancelled or revoked by the Fund by the next business day following receipt by the Fund.
In an attempt to deter excessive trading in omnibus accounts, the Fund or its agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Fund’s ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Fund’s excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Fund by a collective investment trust managed by the Adviser; (iv) transactions in the Fund by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Fund’s policies and procedures regarding excessive trading may be modified at any time by the Fund’s Trustees.
Excessive Trading Risks
Excessive trading may present risks to the Fund’s long-term shareholders. Excessive trading into and out of the Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of the Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by the Fund despite the Fund’s adoption of policies and procedures intended to reduce the Fund’s exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Fund to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Fund may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Fund and its agents. This makes the Fund’s identification of excessive trading transactions in the Fund through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Fund encourages intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Fund cannot eliminate completely the possibility of excessive trading.
32 | Janus Investment Fund

Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Fund.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of the Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for the Fund at janushenderson.com/reports. A complete schedule of the Fund’s portfolio holdings is also available in the annual and semiannual financial statements located in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. The Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom equity securities ranked by performance attribution, including the percentage attribution to Fund performance, average Fund weighting, and other relevant data points, may be provided monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s SAI.
Shareholder services and account policies
Address Changes
For the easiest way to change the address on your account, visit janushenderson.com/individual. You may also call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Include the name of the Janus Henderson fund(s) you hold, the account number(s), the name(s) on the account, and both the old and new addresses. Certain options may be suspended for 10 days following an address change unless a signature guarantee is provided.
Bank Account Changes
For the easiest way to change your bank account of record or add new bank account information to your account, visit janushenderson.com/individual. You may also send a written request signed by the shareholder of record or by each shareholder of record if more than one. Certain accounts may require a written notice and, in some instances, bank privileges may not be available. If multiple account owners are named on the added bank account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.
You may revoke the authorization to use your bank account information at any time by visiting janushenderson.com/individual, or by sending a written request by mail (Janus Henderson, P.O. Box 219109, Kansas City, MO 64121-9109), or by telephone at 1-800-525-3713. Your request will be processed within a reasonable amount of time upon its receipt.
33 | Janus Investment Fund

Distributions
Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janushenderson.com/individual, call a Janus Henderson representative, or send a written request signed by one or more shareholder(s) of record.
Your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.
Involuntary Redemptions
The Fund reserves the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Fund. This includes, but is not limited to, accounts that the Fund or its agents believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.
Lost (Unclaimed/Abandoned) Accounts
It is important that the Fund maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund as undeliverable. Based upon statutory requirements for returned mail, the Adviser will attempt to locate the shareholder or rightful owner of the account. If the Adviser is unable to locate the shareholder, then the Adviser is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
Online and Telephone Transactions
You may initiate many transactions through janushenderson.com/individual or by calling Janus Henderson XpressLine. You may also contact a Janus Henderson representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please call a Janus Henderson representative. The Fund and its agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.
Your ability to access your account or transact business electronically may be impacted due to unexpected circumstances, such as system outages, or during periods of increased web activity. For example, periods of substantial market change or other unexpected events can contribute to high call volumes, which may delay your ability to reach a Janus Henderson representative by telephone.
If you experience difficulty transacting business with us through a particular method, please consider using an alternate method, such as visiting janushenderson.com/individual, calling Janus Henderson XpressLine, contacting a Janus Henderson representative by telephone, or sending written instructions to complete your transaction. Please remember that purchase, exchange, or redemption requests must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE in order to receive that day’s NAV.
Your account information, including online credentials, should be kept private, and you should immediately review any account statements that you receive from Janus Henderson. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus Henderson immediately about any transactions you believe to be unauthorized.
Registration Changes
To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janushenderson.com/individual or call a Janus Henderson representative for further instructions.
Statements, Reports, and Prospectuses
We will send you a confirmation upon the completion of individual account transactions. We will also send you quarterly account statements detailing financial transactions on open accounts processed year-to-date. Systematic transactions are
34 | Janus Investment Fund

confirmed on quarterly statements unless otherwise requested. Confirmations and quarterly account statements will be sent to the account address of record unless you have elected to receive online statements. The Fund reserves the right to charge a fee for additional account statement requests.
At account setup, or any time thereafter, you may elect (at janushenderson.com/edelivery) to discontinue physical delivery of quarterly account statements and/or confirmations, and instead receive an e-mail notification when they are available online. All statements are available online regardless of your delivery option elections (to view, you must first establish online access at janushenderson.com/individual).
The Fund produces shareholder reports semiannually, and updates its prospectus annually. You may elect to receive shareholder reports and prospectus updates electronically at janushenderson.com/edelivery. The Fund’s fiscal year ends June 30.
Unless you instruct Janus Henderson otherwise by contacting a Janus Henderson representative, the Fund will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Fund receives your instructions.
Taxpayer Identification Number
On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Fund to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Fund for any penalty that the IRS may impose.
Temporary Suspension of Services
The Fund or its agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Fund may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Fund to redeem its Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.
In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (i) a natural person age 65 and older, or (ii) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests. We may not be aware of factors suggesting financial exploitation of a Specified Adult and may not be able to identify Specified Adults in all circumstances. Furthermore, we are not required to delay the disbursement of redemption proceeds and do not assume any obligation to do so.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. The Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
37 | Janus Investment Fund

Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. The Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. The Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. The Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. The Fund may purchase or write such options individually or in combination.
Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which the Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Short sales in which the Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that the Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. The Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year period reflects the conversion to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 250% of the average value of its portfolio.
Principal investment strategies
The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies, including, but not limited to, common stocks and depositary receipts. An issuer is deemed to be economically tied to the United States if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the United States; (ii) a majority of the issuer’s revenues are derived from the United States; or (iii) a majority of the issuer’s assets are located in the United States. Under normal circumstances, the Fund seeks to achieve returns with lower volatility over a full market cycle than the Russell 1000® Index (the Fund’s broad-based benchmark index). The Fund seeks to generate such returns with volatility that can range from approximately 0% to 40% lower than the Russell 1000 Index. In this context, volatility refers to the variation in the returns of the Fund and the broad-based benchmark index as measured by the standard deviation of monthly returns. The market capitalization of issuers within the broad-based benchmark index, from which the Fund’s investment universe is derived, will vary, but as of June 30, 2024, it ranged from approximately $170 million to $3.32 trillion.
The Fund pursues its investment objective by applying a proprietary methodology to construct an investment portfolio of equity securities from a universe of the 750 largest U.S. issuers in the Russell 1000 Index by market capitalization whose securities are also characterized by broad options market liquidity. Portfolio management applies a systematic investment process that monitors day-to-day movements in options prices on individual U.S. issuers for indicators of upside (or good) and downside (or bad) volatility to forecast their risk and reward. In applying this investment process, portfolio management seeks to avoid issuers whose upside volatilities are perceived to be lower and whose downside volatilities are perceived to be higher, resulting in a portfolio that is expected to generate returns with lower volatility over a full market cycle. Although the Fund is generally expected to underperform the Russell 1000 Index in sharply rising markets, this strategy seeks to minimize losses in down markets.
The Fund may engage in active and frequent trading to achieve its investment objective.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
3 | Janus Henderson Adaptive Risk Managed U.S. Equity Fund

Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Industry and Sector Risk.Although the Fund does not concentrate its investments in specific industries, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Companies in the same industry or economic sector may be similarly affected by negative economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may offset gains or increase losses in the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.
Depositary Receipts Risk.Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency.
Volatility Risk.There is no guarantee that the Fund’s strategy to minimize volatility will be successful. Securities in the Fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the Fund’s strategy to minimize volatility could limit the Fund’s gains in rising markets.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class I Shares, Class A Shares, Class C Shares, and Class S Shares of the Fund commenced operations on July 6, 2009, after the reorganization of each corresponding class of shares of Janus Adviser INTECH Risk-Managed Value Fund (the “JAD Predecessor Fund”) into each respective share class of the Fund. Class T Shares of the Fund commenced operations on July 6, 2009. Class N Shares of the Fund commenced operations on October 28, 2014.
The performance shown for Class I Shares, Class A Shares, Class C Shares, and Class S Shares for periods prior to July 6, 2009, reflects the historical performance of the JAD Predecessor Fund’s Class I Shares, Class A Shares, Class C Shares, and Class S Shares prior to the reorganization, calculated using the fees and expenses of each respective share class of the JAD Predecessor Fund, net of any applicable fee and expense limitations or waivers.
The performance shown for Class T Shares for periods prior to July 6, 2009, reflects the historical performance of the JAD Predecessor Fund’s Class I Shares prior to the reorganization, calculated using the fees and expenses of Class T Shares, without the effect of any fee and expense limitations or waivers. If Class T Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown may have been different.
The performance shown for Class N Shares reflects the performance of the Fund’s Class I Shares from July 6, 2009 to October 28, 2014, calculated using the fees and expenses of Class I Shares, net of any applicable fee and expense limitations or waivers. The performance shown for Class N Shares for periods prior to July 6, 2009, reflects the historical performance of the JAD Predecessor Fund’s Class I Shares prior to the reorganization, calculated using the fees and expenses of Class I Shares of the JAD Predecessor Fund, net of any applicable fee and expense limitations or waivers. If
4 | Janus Henderson Adaptive Risk Managed U.S. Equity Fund

Class N Shares of the Fund had been available during periods prior to October 28, 2014, the performance shown may have been different.
The performance shown for the periods following the Fund’s commencement of Class I Shares, Class A Shares, Class C Shares, Class S Shares, Class N Shares, and Class T Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 10, 2022, the Fund changed its investment strategy. Performance prior to June 10, 2022 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

The one year return is calculated to include the contingent deferred sales charge.
The Fund’s broad-based benchmark index is the Russell 1000 Index. The Fund’s additional benchmark is the S&P 500 Minimum Volatility Index. The indices are described below.
The Russell 1000 Index measures the performance of the large-cap segment of the U.S. equity universe.
The S&P 500 Minimum Volatility Index is designed to reflect a managed-volatility equity strategy that seeks to achieve lower total risk, measured by standard deviation, than the S&P 500 while maintaining similar characteristics.
After-tax returns are calculated using distributions for the Fund’s Class I Shares for the periods following July 6, 2009; and for the JAD Predecessor Fund’s Class I Shares for the periods prior to July 6, 2009. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

After-tax returns are only shown for Class I Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class I Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

Purchases, exchanges, and redemptions can generally be made only through institutional channels, such as financial intermediaries and retirement platforms. You should contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund. Requests must be received in good order by the Fund or its agents (financial intermediary or plan sponsor, if applicable) prior to the close of the trading session of the New York Stock Exchange in order to receive that day’s net asset value. For additional information, refer to “Purchases,” “Exchanges,” and/or “Redemptions” in the Prospectus.
Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase Class A Shares, Class C Shares, Class S Shares, Class I Shares, or Class T Shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Shareholder Fees” are fees paid directly from your investment and may include sales loads.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Distribution/Service (12b-1) Fees.” Because 12b-1 fees are charged as an ongoing fee, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. Distribution/Service (12b-1) Fees include a shareholder servicing fee of up to 0.25% for Class C Shares.
A contingent deferred sales charge of up to 1.00% may be imposed on certain redemptions of Class A Shares bought without an initial sales charge and then redeemed within 12 months of purchase. The contingent deferred sales charge is not reflected in the Example in the Fund Summary.
A contingent deferred sales charge of 1.00% generally applies on Class C Shares redeemed within 12 months of purchase. The contingent deferred sales charge may be waived for certain investors, as described in the Shareholder’s Guide.
“Other Expenses”
°
for Class A Shares, Class C Shares, and Class I Shares, may include administrative fees charged by intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Fund.
°
for Class S Shares and Class T Shares, include an administrative services fee of 0.25% of the average daily net assets of each class to compensate Janus Henderson Services US LLC (the “Transfer Agent”), the Fund’s transfer agent, for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of retirement plan participants, pension plan participants, or other underlying investors investing through institutional channels.
°
for all classes, include acquired fund fees and expenses, which are indirect expenses the Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. Such amounts are less than 0.01%.
°
for all classes, may include reimbursement to the Adviser of its out-of-pocket costs for services as administrator and to the Transfer Agent of its out-of-pocket costs for serving as transfer agent and providing, or arranging by others the provision of, servicing to shareholders.

include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse the Fund’s “Total Annual Fund Operating Expenses” to a certain limit for at least a one-year period commencing on October 28, 2024. The expense limit is described in the “Management Expenses” section of this Prospectus.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, the Fund will provide shareholders with at least 60 days’ notice prior to changing the 80% investment policy. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary section, including the types of securities the Fund may invest in when pursuing its investment objective. This section also describes investment strategies and policies that the Fund may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since the Fund’s composition can change over time. Except for the Fund’s policies with respect to illiquid investments, borrowing, and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if the Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
The Fund’s investment process seeks to achieve returns with lower volatility over a full market cycle than the Russell 1000 Index. The investment process involves selecting stocks from a universe of the 750 largest U.S. issuers in the Russell 1000 Index by market capitalization whose securities are also characterized by broad options market liquidity. Portfolio management applies a systematic investment process that monitors day-to-day movements in options prices on individual U.S. issuers for indicators of upside (or good) and downside (or bad) volatility to forecast their risk and reward. In applying this investment process, portfolio management seeks to avoid issuers whose upside volatilities are perceived to be lower and whose downside volatilities are perceived to be higher, resulting in a portfolio that is expected to generate returns with lower volatility over a full market cycle.
Cash Position
The Fund normally remains as fully invested as possible and does not seek to lessen the effects of a declining market through hedging or temporary defensive positions. The Fund may use futures, options, and other derivatives, to gain exposure to the stock market pending investment of cash balances or to meet liquidity needs. There is no guarantee that these types of derivative investments will work and their use could cause lower returns or even losses to the Fund. To the extent the Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
Commercial Paper
The Fund may invest in commercial paper. Commercial paper refers to short-term, unsecured promissory notes issued by banks, corporations and other borrowers to finance short-term credit needs. Commercial paper is usually sold on a discount basis and typically has a maturity at the time of issuance not exceeding nine months. The Fund may invest in investment grade commercial paper (e.g., that is rated Prime-3 or higher by Moody’s Investors Service, Inc. (“Moody’s”) or A-3 or higher by Standard & Poor’s Ratings Services (“S&P”) or, if unrated by Moody’s or S&P, is issued by a company having an outstanding debt issue rated investment grade).
Derivatives
The Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. The Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
9 | Janus Investment Fund

Exchange-Traded Funds
The Fund may invest in exchange-traded funds (“ETFs”). ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of the Fund, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. The Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
The Fund may invest in foreign securities. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities.
Portfolio Turnover
The rebalancing techniques used by the Fund typically result in higher portfolio turnover compared to a “buy and hold” fund strategy. Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on the Fund’s performance. Portfolio turnover rates are not a factor in making buy and sell decisions. The “Financial Highlights” section of this Prospectus shows the Fund’s historical turnover rates.
REITs and Real Estate-Related Securities
The Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Securities Lending
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When the Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, the Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the
10 | Janus Investment Fund

collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to the Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Other Types of Investments
Unless otherwise stated within its specific investment policies, the Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Fund. If successful, they may benefit the Fund by earning a return on the Fund’s assets or reducing risk; however, they may not achieve the Fund’s investment objective.
Risks of the Fund
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Fund. Because the Fund may invest substantially all of its assets in common stocks, the main risk is the risk that the value of the stocks it holds might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
Commercial Paper Risk.Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, the Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of swaps, futures, and options). The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.
11 | Janus Investment Fund

Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which the Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, the Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because the Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.
Foreign Exposure Risk.Within the parameters of its specific investment policies, the Fund may invest in foreign equity and debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because the Fund’s performance may depend on factors other than the performance of a particular company. Such risks include currency risk, foreign market risk, geographic concentration risk, political and economic risk, and regulatory risk due to greater exposure to a particular country or geographic region.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of the Fund’s shares. The Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in the Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares.
Market Risk.The value of the Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
12 | Janus Investment Fund

Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Money Market Fund Investment Risk.The Fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and the Fund may lose money. To the extent the Fund transacts in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share net asset value at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable net asset value could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their net asset values. Certain money market funds have in the past failed to maintain stable net asset values, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the Securities and Exchange Commission (the “SEC”) require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s net asset value per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating net asset value requirements. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund.
Recently adopted amendments to Rule 2a-7 also require certain money market funds, excluding Government Money Market Funds and Retail Money Market Funds, to impose mandatory liquidity fees when a fund experiences net redemptions that exceed 5% of its net assets, unless the fund’s liquidity costs are de minimis (i.e., less than 1 basis point).
There can be no assurance that the Fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market fund in which it invests.
REIT and Real Estate-Related Securities Risk.To the extent the Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which the Fund may invest focus their assets in specific real property sectors, such as hotels, shopping
13 | Janus Investment Fund

malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. The Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing the return to the Fund on its investment in such company.
Small- and Mid-Sized Companies Risk.The Fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Fund reimburses the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Fund’s Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Fund. The Fund pays these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs expenses, including the distribution and shareholder servicing fees (12b-1 fee), administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund must pay.
The following table reflects the Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual compensation rate paid by the Fund to the Adviser after any applicable fee waivers and/or expense reimbursements. The rate shown is a fixed rate based on the Fund’s average daily net assets.

A discussion regarding the basis for the Trustees’ approval of the Fund’s investment advisory agreement is included in the Fund’s semiannual report (for the period ended December 31, 2023) and in the Fund’s financial statements (for the period ended June 30, 2024, and moving forward). You can request the Fund’s semiannual reports or financial statements (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus Henderson representative at 1-877-335-2687. This information is also available, free of charge, at janushenderson.com/info.
Expense Limitation
The Adviser has contractually agreed to waive the advisory fee payable by the Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed 0.59% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. Prior to June 10, 2024, the Adviser had contractually agreed to waive 0.05% of its advisory fee for a period of two years. For information about how the expense limit (as applicable) affect the total expenses of the Fund, see the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus.
Portfolio management
Janus Henderson Adaptive Risk Managed U.S. Equity Fund
Ashwin Alankar, Ph.D., is Head of Global Asset Allocation of Janus Henderson Investors. He is Executive Vice President and Portfolio Manager of Janus Henderson Adaptive Risk Managed U.S. Equity Fund, which he has managed since June 2022. Mr. Alankar is also Portfolio Manager of other Janus Henderson accounts. He joined the Adviser in 2014. Mr. Alankar holds a Bachelor of Science degree in Mathematics and Chemical Engineering and a Master of Science degree in Chemical Engineering from the Massachusetts Institute of Technology, and a Ph.D. in Finance from the University of California at Berkeley’s Haas School of Business.
Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of his individual ownership in the Fund(s) that he manages, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that the Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.

Other information
CLOSED FUND POLICIES
The Fund may limit sales of its Shares to new investors. If sales of the Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Fund
The Fund is distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well. The date you receive your distribution may vary depending on how your intermediary processes trades. Please consult your intermediary for details.
How Distributions Affect the Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of the Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in the Fund’s daily net asset value (“NAV”). The share price of the Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, the Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of the Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund without any sales charge. To receive distributions in cash, contact your financial intermediary, or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with the Fund. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment
18 | Janus Investment Fund

income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of the Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, the Fund is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary (or the Fund, if you hold Class N Shares directly with the Fund) will report cost basis information to you and to the IRS. Your intermediary (or the Fund) will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method, unless you hold Class N Shares directly with the Fund in which case the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
19 | Janus Investment Fund

Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s guide
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.
The Fund offers multiple classes of shares in order to meet the needs of various types of investors.
Class A Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. Class A Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services on behalf of their clients. In addition, Class A Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. Class A Shares may be offered without an initial sales charge to certain classes of investors such as purchases through certain retirement platforms, certain self-directed brokerage platforms where the financial intermediary is the broker of record, or fee-based platforms. See “Qualifying for a Waiver or Reduction of Class A Shares Sales Charge” in this Shareholder’s Guide for additional details.
Class C Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, and bank trust platforms. Class C Shares pay up to 0.75% of net assets for payment to financial intermediaries for the provision of distribution services and up to 0.25% of net assets for the provision of shareholder services on behalf of their clients. In addition, Class C Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class C Shares are closed to investments by new employer-sponsored retirement plans and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares. Other share classes described in this Prospectus as eligible for investment by retirement plans are unaffected by this closure.
Class C Shares currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares. For more information, please refer to “Conversion of Class C Shares to Class A Shares.”
Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class S Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. Class I Shares may also be available to retail investors purchasing in qualified or nonqualified accounts where such accounts are held through an omnibus account at your broker or financial intermediary. For more information please refer to Appendix A which accompanies this Prospectus. Class I Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. In addition to these fees and expenses paid by Class I Shares, your broker or financial intermediary may impose a commission or other sales charge on purchases. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative.
Class N Shares are generally available only to financial intermediaries purchasing on behalf of: 1) certain adviser-assisted, employer-sponsored retirement plans, including 401(k) plans, 457 plans, 403(b) plans, Taft-Hartley multi-employer plans, profit-sharing and money purchase pension plans, defined benefit plans, and certain welfare benefit plans, such as health savings accounts, and nonqualified deferred compensation plans; and 2) institutional investors and retail investors purchasing in qualified or nonqualified accounts, whose accounts are held through an omnibus account at their financial intermediary,
21 | Janus Investment Fund

and where the financial intermediary requires no payment or reimbursement from the Fund, the Adviser or its affiliates, for distribution-related or other shareholder services. Your broker or financial intermediary may impose a commission or other sales charge on purchases of Class N Shares. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative. Class N Shares also are available to Janus Henderson proprietary products. Class N Shares also are available to certain direct institutional investors approved by the Distributor including, but not limited to, corporations, certain retirement plans, public plans, and foundations and endowments, subject to minimum investment requirements.
Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class T Shares pay up to 0.25% of net assets to financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
The Shares are not offered directly to individual investors. Consult with your financial intermediary representative for additional information on whether the Shares are an appropriate investment choice. Certain funds may not be available through certain of these intermediaries and not all financial intermediaries offer all classes of shares. If your financial intermediary offers more than one class of shares, you should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. For instructions on how to purchase, exchange, or redeem Shares, contact your financial intermediary or refer to your plan documents. For Class N Shares held directly with the Fund, please contact a Janus Henderson representative at 1-800-333-1181.
Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by the Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
The price you pay for purchases of Shares is the public offering price, which is the NAV next calculated after your request is received in good order by the Fund or its agents, plus, for Class A Shares, any applicable initial sales charge. The price you pay to sell Shares is also the NAV, although for Class A Shares and Class C Shares, a contingent deferred sales charge may be taken out of the proceeds. For Class I Shares or Class N Shares, although purchases and redemptions are made at the net asset value calculated after your order is received by the Fund, you may be charged a commission by your broker or other financial institution. The nature and amount of the commission and the times at which it may be collected are determined by your broker. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares. In order to receive a day’s price, your order must be received in good order by the Fund or its agents by the close of the trading session of the NYSE.
Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is
22 | Janus Investment Fund

traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of the Fund’s portfolio securities and the reflection of such change in the Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of the Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by the Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used. Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Fund under the arrangements made between your financial intermediary or plan sponsor and its customers. The Fund is not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Choosing a share class
Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class T Shares are offered by this Prospectus. The Fund offers multiple classes of shares in order to meet the needs of various types of investors. For more
23 | Janus Investment Fund

information about these classes of Shares and whether or not you are eligible to purchase these Shares, please call 1-877-335-2687.
Each class represents an interest in the same portfolio of investments, but has different charges and expenses, allowing you to choose the class that best meets your needs. For an analysis of fees associated with an investment in each share class or other similar funds, please visit www.finra.org/fundanalyzer. When choosing a share class, you should consider:
how much you plan to invest;
how long you expect to own the shares;
the expenses paid by each class; and
for Class A Shares and Class C Shares, whether you qualify for any reduction or waiver of any sales charges.

Distribution, servicing, and administrative fees
Distribution and Shareholder Servicing Plans
Under separate distribution and shareholder servicing plans adopted in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended, for Class A Shares and Class S Shares (each a “Plan”) and Class C Shares (the “Class C
25 | Janus Investment Fund

Plan”), the Fund pays the Distributor a fee for the sale and distribution and/or shareholder servicing of the Shares based on the average daily net assets of each, at the following annual rates:
Class
12b-1 Fee for the Fund
Class A Shares
0.25%
Class C Shares
1.00%(1)
Class S Shares
0.25%
(1) 
Up to 0.75% of this fee is for distribution services and up to 0.25% of this fee is for shareholder services.
Under the terms of each Plan, the Trust is authorized to make payments to the Distributor for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Fund.
The Distributor is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although the Distributor may, pursuant to a written agreement between the Distributor and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.
Financial intermediaries may from time to time be required to meet certain criteria in order to receive 12b-1 fees. The Distributor is entitled to retain some or all fees payable under each Plan in certain circumstances, including when there is no broker of record or when certain qualification standards have not been met by the broker of record.
Because 12b-1 fees are paid out of the Fund’s assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.
Administrative Fees
Class A Shares, Class C Shares, and Class I Shares
Certain, but not all, intermediaries may charge fees for administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided by intermediaries on behalf of shareholders of the Fund. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent pays these administrative fees to intermediaries on behalf of the Fund. The Transfer Agent is then reimbursed by the Fund for such payments. Because the form and amount charged varies by intermediary, the amount of the administrative fee borne by the class is an average of all fees charged by intermediaries. In the event an intermediary receiving payments from the Transfer Agent on behalf of the Fund converts from a networking structure to an omnibus account structure, or otherwise experiences increased costs, fees borne by the Shares may increase. The Fund’s Trustees have set limits on fees that the Fund may incur with respect to administrative fees paid for omnibus or networked accounts. Such limits are subject to change by the Trustees in the future.
Class S Shares and Class T Shares
The Transfer Agent receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class S Shares and Class T Shares of the Fund for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Fund. Order processing includes the submission of transactions through the NSCC or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent expects to use all or a significant portion of this fee to compensate intermediaries and retirement plan service providers for providing these services to their customers who invest in the Fund. The Transfer Agent or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to the Fund.
26 | Janus Investment Fund

For all share classes, the Transfer Agent also seeks reimbursement for costs it incurs as transfer agent and for providing servicing.
Payments to financial intermediaries by the Adviser or its affiliates
From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries that sell certain classes of Shares of the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Sales- and asset-based payments currently range up to 25 basis points on sales and up to 20 basis points on average annual net assets of shares held through the intermediary and are subject to change. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus Henderson funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Payments made with respect to certain classes of Shares may create an incentive for an intermediary to promote or favor other share classes of the Janus Henderson funds. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries, including, but not limited to, the share class or share classes selected by the financial intermediary for a particular channel, platform or investor type, whether such class is open to new investors on a particular platform or channel, the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness of the intermediary to cooperate with the Adviser’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors may change from time to time. Broker-dealer firms currently receiving or expected to receive these fees are listed in the SAI.
In addition, the Adviser, the Distributor, or their affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the NSCC or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services.
The Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments, reimbursements, and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example,
27 | Janus Investment Fund

placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. However, as described elsewhere in this Prospectus, your financial adviser and/or his or her firm may also receive 12b-1 fees and/or administrative services fees in connection with your purchase and retention of Janus Henderson funds. When such fees are combined with the payments described above, the aggregate payments being made to a financial intermediary may be substantial. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
With the exception of Class N Shares, purchases of Shares may generally be made only through institutional channels such as financial intermediaries and retirement platforms. Class N Shares may be purchased directly with the Fund in certain circumstances as described in the eligibility discussion at the beginning of this “Shareholder’s Guide” section. Contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with the Adviser or refer to your plan documents for information on how to invest in the Fund, including additional information on minimum initial or subsequent investment requirements. Under certain circumstances, the Fund may permit an in-kind purchase of Shares. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Fund’s behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Fund or that provide services in connection with investments in the Fund. You should consider such arrangements when evaluating any recommendation of the Fund.
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading. For more information about the Fund’s policy on excessive trading, refer to “Excessive Trading.”
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary (or the Adviser, if you hold Class N Shares directly with the Fund) is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary (or the Adviser, if you hold Class N Shares directly with the Fund) may temporarily limit additional share purchases. In addition, your financial intermediary (or the Adviser, if you hold Class N Shares directly with the Fund) may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary (or a Janus Henderson representative, if you hold Class N Shares directly with the Fund) if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.

Minimum Investment Requirements
Class A Shares, Class C Shares, Class S Shares, and Class T Shares
The minimum investment is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. In addition, shares held through certain supermarket and/or self-directed brokerage accounts, or through wrap programs, may not be subject to these minimums. Investors should refer to their intermediary for additional information.
The maximum purchase in Class C Shares is $500,000 for any single purchase. The sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $500,000 of Fund shares. Effective on or about December 9, 2024, the maximum purchase in Class C Shares will change to $250,000 for any single purchase. At that time, the sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $250,000 of Fund shares.
Class I Shares
Accounts offered through an intermediary institution must meet the minimum investment requirements of $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Directors, officers, and employees of Janus Henderson Group plc (“JHG”) and its affiliates, as well as Trustees and officers of the Fund, may purchase Class I Shares through certain financial intermediaries’ institutional platforms. For more information about this program and eligibility requirements, please contact a Janus Henderson representative at 1-800-333-1181. Exceptions to these minimums may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts. For additional information, contact your intermediary, plan sponsor, or administrator, as applicable.
Class N Shares
For retail investors whose accounts are held through an omnibus account at their financial intermediary, the minimum investment is $2,500 per Fund account. Investors in certain tax-advantaged accounts or accounts held through certain wrap programs or bank trust platforms may not be subject to this minimum. For institutional investors investing directly with the Fund, the minimum investment is $1 million per Fund account. There is no investment minimum for adviser-assisted, employer-sponsored retirement plans, including health savings accounts. For additional information, contact your intermediary, plan sponsor, administrator, or a Janus Henderson representative, as applicable.
Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class T Shares
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. If you hold Class N Shares directly with the Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
The Fund reserves the right to change the amount of these minimums or maximums from time to time or to waive them in whole or in part.
Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary (or the Adviser, if you hold Class N Shares directly with the Fund) to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus Henderson representative for details.
Initial Sales Charge
Class A Shares
An initial sales charge may apply to your purchase of Class A Shares of the Fund based on the amount invested, as set forth in the table below. The sales charge is allocated between the Distributor and your financial intermediary. Sales charges, as expressed as a percentage of offering price and as a percentage of your net investment, are shown in the table. The dollar
29 | Janus Investment Fund

amount of your initial sales charge is calculated as the difference between the public offering price and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding.

Qualifying for a Waiver or Reduction of Class A Shares Sales Charge
Class A Shares of the Fund may be purchased without an initial sales charge by the following persons (and their family members): (i) registered representatives and other employees of intermediaries that have selling agreements with the Distributor to sell Class A Shares; (ii) directors, officers, and employees of JHG and its affiliates; and (iii) Trustees and officers of the Trust. A “family member” includes, but is not necessarily limited to (based on the reasonable discretion of the Adviser), a qualifying person’s sibling, spouse or domestic partner, lineal ascendant (mother, father, grandmother, grandfather, great-grandmother, great-grandfather), lineal descendant (son, daughter, step-son, step-daughter, grandson, granddaughter, great-grandson, great-granddaughter) or any sibling, spouse or domestic partner of a family member who is a lineal descendant or ascendant of a qualifying person. In addition, the initial sales charge may be waived on purchases of Class A Shares by the following persons: (i) investors purchasing Class A Shares through financial intermediaries on behalf of certain adviser-assisted, employer-sponsored retirement plans, including defined contribution plans, defined benefit plans and other welfare benefit plans such as health savings accounts and voluntary employees’ beneficiary association trust accounts; (ii) investors purchasing Class A Shares through a financial intermediary’s self-directed brokerage platform where the financial intermediary is the broker of record; and (iii) investors purchasing Class A Shares through fee-based broker-dealers or financial advisors, primarily on their advisory account platform(s) where such broker-dealer or financial advisor imposes additional fees for services connected to the advisory account. Adviser-assisted, employer-sponsored defined contribution plans include, for example, 401(k) plans, 457 plans, 403(b) plans, profit sharing and money purchase pension plans. For purposes of qualifying for a waiver of the initial sales charge, the following retirement accounts are not eligible: 403(b) custodial accounts where shares are held on behalf of the individual, and not on behalf of the plan or plan trust, SEP IRAs, Simple IRAs, SAR-SEPs, or Keogh plans. To facilitate the waiver of a sales charge, the Distributor requires an agreement with the financial intermediary submitting trades on behalf of eligible investors.
You may be able to lower your Class A Shares sales charge under certain circumstances. For example, you can combine Class A Shares and Class C Shares you already own (either in this Fund or certain other Janus Henderson funds) with your current purchase of Class A Shares of the Fund and certain other Janus Henderson funds (including Class C Shares of those funds) to take advantage of the breakpoints in the sales charge schedule as set forth above. Certain circumstances under which you may combine such ownership of Shares and purchases are described below. Contact your financial intermediary for more information.
In order to obtain a sales charge discount, you should inform your financial intermediary of other accounts in which there are Fund holdings eligible to be aggregated to meet a sales charge breakpoint. These other accounts may include the accounts described under “Aggregating Accounts.” You may need to provide documents such as account statements or confirmation statements to prove that the accounts are eligible for aggregation. The Letter of Intent described below requires historical cost information in certain circumstances. You should retain records necessary to show the price you paid to purchase Fund shares, as the Fund, its agents, or your financial intermediary may not retain this information.
Right of Accumulation.You may purchase Class A Shares of the Fund at a reduced sales charge by aggregating (i) the dollar amount of the new purchase (measured by the offering price) with (ii) your holdings in all Class A Shares of the Fund and certain other classes (Class A Shares and Class C Shares of the Trust) of Janus Henderson funds held by you, and held in the accounts identified under “Aggregating Accounts” (“collective holdings”). Subject to your financial intermediary’s or record keeper’s capabilities, collective holdings will be calculated as the higher of (i) the current value of such holdings (the market value) as of the day prior to your new purchase or (ii) the amount initially invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the cost value). The applicable sales charge will be applied to such aggregated amount. In order for your purchases and collective holdings to be aggregated for purposes of qualifying for a reduced sales charge, they must have been made through one financial intermediary and you must provide sufficient information to your financial intermediary at the time of purchase to permit verification that the purchase qualifies for the reduced sales charge. The qualification of a purchase for the reduced sales charge does not ensure the future availability of the right of accumulation, which is subject to modification or discontinuance at any time.
Letter of Intent.You may obtain a reduced sales charge on Class A Shares by signing a Letter of Intent indicating your intention to purchase $50,000 or more of Class A Shares (including Class A Shares in other series of the Trust) over a 13-month period. The term of the Letter of Intent will commence upon the date you sign the Letter of Intent. Investments made prior to the signing date are not aggregated with, and are not eligible to be included toward, the investment goal.
You must refer to such Letter when placing orders. With regard to a Letter of Intent, the amount of investment for purposes of applying the sales load schedule includes (i) the historical cost (what you actually paid for the shares at the time of
31 | Janus Investment Fund

purchase, including any sales charges) of all Class A Shares acquired during the term of the Letter of Intent, minus (ii) the value of any redemptions of Class A Shares made during the term of the Letter of Intent. Capital appreciation, capital gains, and reinvested dividends earned during the Letter of Intent period do not apply toward its completion. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. A portion of shares purchased may be held in escrow to pay for any sales charge that may be applicable. If the goal is not achieved within the period, you must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed. Please contact your financial intermediary to obtain a Letter of Intent application.
Aggregating Accounts.To take advantage of lower Class A Shares sales charges on large purchases or through the exercise of a Letter of Intent or right of accumulation, investments made by you, your spouse, and your children under age 21 may be aggregated if made for your own account(s) and/or certain other accounts such as:
trust accounts established by the above individuals (or the accounts of the primary beneficiary of the trust if the person who established the trust is deceased);
solely controlled business accounts; and
single participant retirement plans.
To receive a reduced sales charge under rights of accumulation or a Letter of Intent, you must notify your financial intermediary of any eligible accounts that you, your spouse, and your children under age 21 have at the time of your purchase.
You may access information regarding sales loads, breakpoint discounts, and purchases of the Fund’s shares, free of charge, and in a clear and prominent format, on our website at janushenderson.com/breakpoints, and by following the appropriate hyperlinks to the specific information.
Conversion of Class C Shares to Class A Shares
The Fund currently implements an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month of the eighth anniversary of the date of purchase. Class C Shares purchased through the reinvestment of dividends and other distributions on Class C Shares will convert to Class A Shares at the same time as the Class C Shares with respect to which they were purchased.
For Class C Shares held in omnibus accounts on intermediary platforms, the Fund will rely on these intermediaries to implement this conversion feature. Your financial intermediary may have separate policies and procedures as to when and how Class C Shares may be converted to Class A Shares. Please contact your financial intermediary for additional information.
It is expected that the conversion of Class C Shares to Class A Shares of the same Fund will not result in a taxable event. Please consult your tax adviser for further information.
Commission on Class C Shares
The Distributor may compensate your financial intermediary at the time of sale at a commission rate of 1.00% of the net asset value of the Class C Shares purchased. Service providers to financial intermediaries will not receive this amount if they receive 12b-1 fees from the time of initial investment of assets in Class C Shares.
Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (“CDSC”) waivers. In all instances, it is the shareholder’s responsibility to notify the Fund, or the shareholder’s financial intermediary at the time of purchase, of any relationship or other facts qualifying the shareholder for sales charge waivers or discounts. Certain sales charge waivers and/or discounts are described in Appendix A – Intermediary Sales Charge Waivers and Discounts. These sales charge waivers and/or discounts are available only if you purchase your shares through the designated intermediaries. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares through another intermediary to receive these waivers or discounts.
32 | Janus Investment Fund

Exchanges
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with the Fund or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received. The Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
You must meet the minimum investment amount for each fund.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. The Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. The Fund will work with intermediaries to apply the Fund’s exchange limits. However, the Fund may not always have the ability to monitor or enforce the trading activity in such accounts.
The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Class C Shares are closed to investments by new employer-sponsored retirement plans, and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares.
Your Class C Shares that have been held for eight years will automatically convert to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month in which the eighth anniversary of the date of purchase occurs. For more information refer to “Conversion of Class C Shares to Class A Shares.”
Waiver of Sales Charges
Class A Shares received through an exchange of Class A Shares of another fund of the Trust will not be subject to an initial sales charge. In addition, Class A Shares received through an exchange of Class C Shares due to an intermediary-driven conversion or an automatic conversion after eight years, or a conversion from a fee-based account to a brokerage account, will not be subject to an initial sales charge. Class A Shares or Class C Shares received through an exchange of Class A Shares or Class C Shares, respectively, of another fund of the Trust will not be subject to any applicable CDSC at the time of the exchange. CDSC applicable to redemptions of Class A Shares or Class C Shares will continue to be measured on the Shares received by exchange from the date of your original purchase. For more information about the CDSC, please refer to “Redemptions.” While Class C Shares do not have any front-end sales charges, their higher annual fund operating expenses mean that over time, you could end up paying more than the equivalent of the maximum allowable front-end sales charge.
Redemptions
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
Redemptions, like purchases, may generally be effected only through financial intermediaries, retirement platforms, and by certain direct institutional investors holding Class N Shares. Please contact your financial intermediary or a Janus Henderson
33 | Janus Investment Fund

representative (1-800-333-1181) if you hold Class N Shares directly with the Fund or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of the Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by the Fund or its agents. Redemption proceeds, less any applicable CDSC for Class A Shares or Class C Shares, will normally be sent within two business days following receipt of the redemption order. The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. If you hold Class N Shares directly with the Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.

Systematic Withdrawal Plan
Class A Shares and Class C Shares
You may arrange for periodic redemptions of Class A Shares or Class C Shares by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Any resulting CDSC may be waived, however, the maximum annual rate at which shares subject to a CDSC may be redeemed, pursuant to a systematic withdrawal plan, without paying a CDSC, is 12% of the net asset value of the account. Certain other terms and minimums may apply. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Class S Shares, Class I Shares, Class N Shares, and Class T Shares
You may arrange for periodic redemptions by authorizing your financial intermediary (or the Adviser, if you hold Class N Shares directly with the Fund) to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus Henderson representative for details.
Contingent Deferred Sales Charge
Class A Shares and Class C Shares
A 1.00% CDSC may be deducted with respect to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase, unless any of the CDSC waivers listed apply. A 1.00% CDSC will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless a CDSC waiver applies. The CDSC will be based on the lower of the original purchase price or the value of the redemption of the Class A Shares or Class C Shares redeemed, as applicable.
CDSC Waivers
There are certain cases in which you may be exempt from a CDSC charged to Class A Shares and Class C Shares. Among others, these include:
Upon the death or disability of an account owner;
Retirement plans and certain other accounts held through a financial intermediary where no sales charge or commission was paid on the purchase of such shares;
Retirement plan shareholders taking required minimum distributions;
The redemption of Class A Shares or Class C Shares acquired through reinvestment of Fund dividends or distributions;
The portion of the redemption representing appreciation as a result of an increase in NAV above the total amount of payments for Class A Shares or Class C Shares during the period during which the CDSC applied; or
If the Fund chooses to liquidate or involuntarily redeem shares in your account.
To keep the CDSC as low as possible, Class A Shares or Class C Shares not subject to any CDSC will be redeemed first, followed by shares held longest.
Reinstatement Privilege
For each redemption of Class A Shares, you have a one-time right to reinvest the proceeds of such redemption into Class A Shares of the same or another fund within 90 days of the redemption date at the current NAV (without an initial sales charge). You will not be reimbursed for any CDSC paid on your redemption of Class A Shares.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Fund is intended for long-term investment purposes, and the Fund will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Fund’s exchange limits or excessive trading policies and procedures may be cancelled or rescinded by the Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Fund is also available for purchase through third party intermediaries.
35 | Janus Investment Fund

The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Fund monitors for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Fund at all times reserves the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to the Fund.
The Fund’s Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Fund’s excessive trading policies and procedures and may be rejected in whole or in part by the Fund. Transactions accepted by a financial intermediary in violation of the Fund’s excessive trading policies may be cancelled or revoked by the Fund by the next business day following receipt by the Fund.
In an attempt to deter excessive trading in omnibus accounts, the Fund or its agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Fund’s ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Fund’s excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Fund by a collective investment trust managed by the Adviser; (iv) transactions in the Fund by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Fund’s policies and procedures regarding excessive trading may be modified at any time by the Fund’s Trustees.
Excessive Trading Risks
Excessive trading may present risks to the Fund’s long-term shareholders. Excessive trading into and out of the Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of the Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by the Fund despite the Fund’s adoption of policies and procedures intended to reduce the Fund’s exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Fund to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Fund may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the
36 | Janus Investment Fund

Fund and its agents. This makes the Fund’s identification of excessive trading transactions in the Fund through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Fund encourages intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Fund cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Fund.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of the Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for the Fund at janushenderson.com/info. A complete schedule of the Fund’s portfolio holdings is also available in the annual and semiannual financial statements included in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. The Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom equity securities ranked by performance attribution, including the percentage attribution to Fund performance, average Fund weighting, and other relevant data points, may be provided monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s SAI.
Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with the Fund) is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with the Fund) is responsible for providing annual and semiannual reports of the Fund. Please contact your financial intermediary or plan sponsor (or the Adviser) to obtain these reports. The Fund’s fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with the Fund) is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor (or the Adviser) is unable to locate the shareholder, then the financial intermediary or plan sponsor (or the Adviser) is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory
37 | Janus Investment Fund

requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Financial highlights
The financial highlights tables are intended to help you understand the Fund’s financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if applicable. The information for the Fund for the fiscal periods ended June 30 has been audited by PricewaterhouseCoopers LLP, whose report, along with the Fund’s financial statements, is included in the Fund’s Form N-CSR and is incorporated by reference into the SAI.
The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in the Shares of the Fund (assuming reinvestment of all dividends and distributions).

Appendix A – intermediary sales charge waivers and discounts
AMERIPRISE FINANCIAL
The following information is provided by Ameriprise Financial:
Sales Charge Reductions and Waivers Available from Certain Financial Intermediaries
The availability of certain sales charge reductions and waivers will depend on whether you purchase fund shares directly from the fund or through a financial intermediary. Financial intermediaries may have different policies and procedures regarding the availability of front-end sales load reductions or waivers or CDSC waivers, which are described below. In all instances, it is the investor’s responsibility to notify the fund or the investor’s financial intermediary at the time of purchase of any relationship or other facts qualifying the investor for sales charge reductions or waivers. For reductions or waivers not available through a particular financial intermediary, investors will have to purchase fund shares directly through another financial intermediary to receive these reductions or waivers.

Front-end sales charge waivers on Class A shares purchased through Ameriprise Financial

For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs or SAR-SEPs.
shares purchased through reinvestment of capital gains and dividend reinvestment when purchasing shares of the same fund (but not any other fund within the same fund family).
shares exchanged from Class C shares of the same fund in the month of or following the seven-year anniversary of the purchase date. To the extent that this prospectus elsewhere provides for a waiver with respect to such shares following a shorter holding period, that waiver will apply to exchanges following such shorter period. To the extent that this prospectus elsewhere provides for a waiver with respect to exchanges of Class C shares for load waived shares, that waiver will also apply to such exchanges.
shares purchased by employees and registered representatives of Ameriprise Financial or its affiliates and their immediate family members.
shares purchased by or through qualified accounts (including IRAs, Coverdell Education Savings Accounts, 401(k)s, 403(b) TSCAs subject to ERISA and defined benefit plans) that are held by a covered family member, defined as an Ameriprise Financial advisor and/or the advisor’s spouse, advisor’s lineal ascendant (mother, father, grandmother, grandfather, great grandmother, great grandfather), advisor’s lineal descendant (son, step-son, daughter, step-daughter, grandson, granddaughter, great grandson, great granddaughter) or any spouse of a covered family member who is a lineal descendant.
shares purchased from the proceeds of redemptions from another fund in the same fund family, provided (1) the repurchase occurs within 90 days following the redemption, (2) the redemption and purchase occur in the same account, and (3) redeemed shares were subject to a front-end or deferred sales load (i.e. Rights of Reinstatement).

EDWARD JONES
The following information is provided by Edward D. Jones & Co., L.P. (“Edward Jones”):
Policies Regarding Transactions Through Edward Jones
Effective on or after January 1, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the same fund family, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.
Breakpoints
Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.
Rights of Accumulation (“ROA”)
The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.
The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.
ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).
Letter of Intent (“LOI”)
Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.
If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.
Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.
Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.
Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions.
Purchases of Class 529 shares made for recontribution of refunded amounts.

The death or disability of the shareholder.
Systematic withdrawals with up to 10% per year of the account value.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. The Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
52 | Janus Investment Fund

Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. The Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. The Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. The Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. The Fund may purchase or write such options individually or in combination.
Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which the Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Short sales in which the Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that the Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. The Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain.

Janus Henderson Global Allocation Fund – Conservative seeks total return through a primary emphasis on income with a secondary emphasis on growth of capital.
Fees and Expenses of the Fund
This table describes the fees and expenses that you may pay if you buy, hold, and sell Shares of the Fund.

(1)
“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which the Fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses the Fund incurs as a result of investing in shares of an underlying fund. The Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any expenses of an underlying fund (acquired fund fees and expenses), shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.14% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including the operating expenses of the underlying funds) are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 111% of the average value of its portfolio.
Principal investment strategies
The Fund seeks to achieve its investment objective by investing in other mutual funds and exchange-traded funds (“ETFs”) (collectively, “underlying funds”) that represent a variety of asset classes and investment styles and provide exposure to issuers that are economically tied to countries throughout the world. Under normal market conditions, the Fund will primarily invest its assets in Janus Henderson underlying funds. The Fund may also invest up to 35% of its assets in underlying funds that
2 | Janus Henderson Global Allocation Fund – Conservative

are not sponsored by the Adviser, which portfolio management expects will predominantly pursue passively-managed investment strategies.
The Fund invests in a diversified portfolio of underlying funds and will normally allocate 50%-65% of its investments to underlying funds that provide varying exposure to fixed-income and money market instruments, 30%-50% of its investments to underlying funds that provide varying exposure to common stocks of U.S.-based companies and international companies, and 0%-20% of its investments to underlying funds that provide exposure to alternative investments and alternative investment strategies. The underlying fixed-income funds encompass a wide range of fixed-income sectors, including corporate bonds, government securities, mortgage- and asset-backed securities, bank loans, securities that are rated below investment grade, and commercial paper, with varying maturities and duration, credit exposure, and regional exposure. The underlying equity funds may invest across a wide range of market capitalizations and segments, including emerging markets, and employ various investment strategies and styles such as growth and value. The underlying alternative funds may invest in various alternative strategies, including, but not limited to, commodities, currencies, and hedge fund strategies. Because it invests in other funds, the Fund is considered a “fund of funds.”
Through its investments in underlying funds, the Fund invests in issuers from several different countries. As a result, the Fund normally will have approximately 40% to 65% of its net assets allocated to non-U.S. investments. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the company’s revenues are derived from outside of the United States; or (iii) a majority of the company’s assets are located outside of the United States. The Fund may also have significant exposure to emerging markets.
In managing the Fund, portfolio management employs a proprietary methodology that combines strategic asset allocation and dynamic asset allocation. The strategic asset allocation process is based on an assessment of long-term return, risk, and correlation expectations of various asset classes and is normally applied on an annual basis. The dynamic asset allocation process gives portfolio management the ability to express shorter-term market views and to react to market changes by adjusting the Fund’s exposure to the underlying funds and is normally applied on a quarterly basis.
When market conditions dictate a more defensive strategy, the Fund or an underlying fund may temporarily hold cash or invest its assets in temporary investments. In that case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Refer to Appendix A of the Prospectus for a brief description of the investment strategies of each of the currently available Janus Henderson underlying funds. The underlying funds, and the Fund’s investment in any underlying fund, may change at any time without prior notice.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking income and, to a lesser extent, growth of capital. The principal risks associated with investing in the Fund and the underlying funds are set forth below.
Fund-Level Risks
Affiliated Underlying Fund Risk.The Adviser has the authority to select and substitute the underlying funds. The Adviser is subject to conflicts of interest in allocating the Fund’s assets among certain Janus Henderson underlying funds both because the fees payable to it by the Janus Henderson underlying funds differ and because the Adviser is also responsible for managing the Janus Henderson underlying funds. In addition, the Adviser’s authority to allocate investments among the Janus Henderson underlying funds and underlying funds that are not sponsored by the Adviser creates conflicts of interest. For example, investing in Janus Henderson underlying funds could cause the Fund to incur higher fees and may cause the Adviser to receive greater compensation, increase assets under management, or support particular investment strategies. The Adviser, however, is a fiduciary to the Fund and is legally obligated to act in its best interest when selecting underlying funds.
Underlying ETF Risk.Underlying funds that are ETFs (“underlying ETFs”) are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an underlying ETF trades at a premium or discount to its net asset value. Underlying ETFs also involve the risk that an active trading market for an underlying ETF’s shares may not develop or be maintained. Similarly, because the value of underlying
3 | Janus Henderson Global Allocation Fund – Conservative

ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an underlying ETF at the most optimal time, which could adversely affect the Fund’s performance. Trading of an underlying ETF’s shares may be halted by the activation of individual or market-wide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an underlying ETF’s shares may also be halted if (i) the shares are delisted from an exchange without first being listed on another exchange or (ii) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Allocation Risk.The Fund’s ability to achieve its investment objective depends largely upon portfolio management’s allocation of assets among the underlying funds and other securities using Janus Henderson’s proprietary strategic asset allocation and dynamic asset allocation methodologies. You could lose money on your investment in the Fund as a result of these allocations. The Fund will typically invest in a number of different underlying funds; however, to the extent that the Fund invests a significant portion of its assets in a single underlying fund, it will be more sensitive to the risks associated with that fund and any investments in which that fund focuses.
Investment Process Risk.No assurance can be given that the Fund’s investment strategy will be successful under all or any market conditions. Although the proprietary strategic asset allocation and dynamic asset allocation methodologies are designed to achieve the Fund’s investment objective, there is no guarantee that they will achieve the desired results, and there is a risk that they may not be successful in identifying how the Fund’s allocations and security exposures should be adjusted in order to reduce the risk of loss while participating in the upside growth of capital markets.
Risks Through Investing in the Underlying Funds
The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the underlying funds realize their respective investment objectives. Similarly, the Fund’s investment performance is directly related to the investment performance of the underlying funds it holds. The Fund is subject to the risk factors associated with the investments of the underlying funds, and will be affected by such risks in direct proportion to the allocation of its assets among the underlying funds. Therefore, to the extent that the Fund invests significantly in a particular underlying fund, the Fund’s performance would be significantly impacted by the performance of such underlying fund. What follows are the main risks associated with the underlying funds, which, in turn, may be considered to be principal risks of the Fund. These risks are subject to change based on the allocation of the Fund’s assets among the underlying funds.
Market Risk.The value of an underlying fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, an underlying fund’s net asset value may fluctuate and it may be more difficult to value or sell an underlying fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Equity Securities Risk.Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of an underlying fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries in which the issuers of securities the underlying fund holds participate.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in an underlying fund’s income or return potential.
4 | Janus Henderson Global Allocation Fund – Conservative

Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price the underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If an underlying fund’s portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing an underlying fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of an underlying fund’s investments. To the extent that an underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.
Small- and Mid-Sized Companies Risk.Certain of the underlying fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holding are also subject to wider price fluctuations and tend to be less liquid that stock of larger or more established companies, which could have a significant adverse effect on an underlying fund’s returns, especially as market conditions change.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that
5 | Janus Henderson Global Allocation Fund – Conservative

controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which an underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, an underlying fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where an underlying fund has invested a significant amount of its assets may have a greater effect on an underlying fund’s performance than it would in a more geographically diversified portfolio.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Portfolio Management Risk.Certain of the underlying funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and/or research process employed for those underlying funds may fail to produce the intended results. Accordingly, such underlying funds may underperform their respective benchmark indexes or other mutual funds with similar investment objectives.
Passive Investment Risk.Certain of the underlying funds are not actively managed and therefore an underlying fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the underlying fund’s specific benchmark index or the selling of shares is otherwise required upon a rebalancing of the specific benchmark index. Maintaining investments in securities without attempting to take defensive positions, regardless of market conditions or the performance of individual securities, could cause an underlying fund’s return to be lower than if it had employed an active strategy.
Volatility Risk.There is no guarantee that Janus Henderson Adaptive Risk Managed U.S. Equity Fund’s, an underlying fund, strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage.
Counterparty Risk.Certain derivative and “over-the-counter” instruments, such as swaps and forwards, are subject to the risk that the other party to a contract will not fulfill its contractual obligations.
Alternative Investments Allocation Risk.There is a risk that the returns provided by alternative investments may be subject to high volatility and that an underlying fund’s portfolio management’s beliefs about the expected returns, risk and correlation properties of one or more of an underlying fund’s investments may be incorrect. There is also a risk that an underlying fund’s investments will correlate with the performance of stocks and bonds to a greater degree than anticipated. All of these factors
6 | Janus Henderson Global Allocation Fund – Conservative

may negatively affect your investment in the Fund and you could lose money. Investment in the underlying funds also involves derivatives, counterparty, leverage, real estate-related, and commodity-linked investment risks.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. Performance information for each underlying fund is available in its prospectus and/or the most recent annual or semiannual report. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 20, 2024, the Fund changed its investment strategy. Performance prior to June 20, 2024 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
The Fund’s broad-based benchmark index is the Bloomberg Global Aggregate Bond Index. The Fund’s additional benchmark is the Global Conservative Allocation Index. The indices are described below.
The Bloomberg Global Aggregate Bond Index is a broad-based measure of the global investment grade fixed-rate debt markets.
The Global Conservative Allocation Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the Bloomberg Global Aggregate Bond Index (60%) and the MSCI All Country World Indexsm (40%).
After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which the Fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses the Fund incurs as a result of investing in shares of an underlying fund. The Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any expenses of an underlying fund (acquired fund fees and expenses), shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.12% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including the operating expenses of the underlying funds) are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
1 Year
3 Years
5 Years
10 Years
Class D Shares
$78
$251
$440
$986
Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 104% of the average value of its portfolio.
Principal investment strategies
The Fund seeks to achieve its investment objective by investing in other mutual funds and exchange-traded funds (“ETFs”) (collectively, “underlying funds”) that represent a variety of asset classes and investment styles and provide exposure to issuers that are economically tied to countries throughout the world. Under normal market conditions, the Fund will primarily invest its assets in Janus Henderson underlying funds. The Fund may also invest up to 35% of its assets in underlying funds that
10 | Janus Henderson Global Allocation Fund – Moderate

are not sponsored by the Adviser, which portfolio management expects will predominantly pursue passively-managed investment strategies.
The Fund invests in a diversified portfolio of underlying funds and will normally allocate 45%-65% of its investments to underlying funds that provide varying exposure to common stocks of U.S.-based companies and international companies, 30%-45% of its investments to underlying funds that provide varying exposure to fixed-income and money market instruments, and 0%-20% of its investments to underlying funds that provide exposure to alternative investments and alternative investment strategies. The underlying equity funds may invest across a wide range of market capitalizations and segments, including emerging markets, and employ various investment strategies and styles such as growth and value. The underlying fixed-income funds encompass a wide range of fixed-income sectors, including corporate bonds, government securities, mortgage- and asset-backed securities, bank loans, securities that are rated below investment grade, and commercial paper, with varying maturities and duration, credit exposure, and regional exposure. The underlying alternative funds may invest in various alternative strategies, including, but not limited to, commodities, currencies, and hedge fund strategies. Because it invests in other funds, the Fund is considered a “fund of funds.”
Through its investments in underlying funds, the Fund invests in issuers from several different countries. As a result, the Fund normally will have approximately 40% to 65% of its net assets allocated to non-U.S. investments. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the company’s revenues are derived from outside of the United States; or (iii) a majority of the company’s assets are located outside of the United States. The Fund may also have significant exposure to emerging markets.
In managing the Fund, portfolio management employs a proprietary methodology that combines strategic asset allocation and dynamic asset allocation. The strategic asset allocation process is based on an assessment of long-term return, risk, and correlation expectations of various asset classes and is normally applied on an annual basis. The dynamic asset allocation process gives portfolio management the ability to express shorter-term market views and to react to market changes by adjusting the Fund’s exposure to the underlying funds and is normally applied on a quarterly basis.
When market conditions dictate a more defensive strategy, the Fund or an underlying fund may temporarily hold cash or invest its assets in temporary investments. In that case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Refer to Appendix A of the Prospectus for a brief description of the investment strategies of each of the currently available Janus Henderson underlying funds. The underlying funds, and the Fund’s investment in any underlying fund, may change at any time without prior notice.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking growth of capital and income. The principal risks associated with investing in the Fund and the underlying funds are set forth below.
Fund-Level Risks
Affiliated Underlying Fund Risk.The Adviser has the authority to select and substitute the underlying funds. The Adviser is subject to conflicts of interest in allocating the Fund’s assets among certain Janus Henderson underlying funds both because the fees payable to it by the Janus Henderson underlying funds differ and because the Adviser is also responsible for managing the Janus Henderson underlying funds. In addition, the Adviser’s authority to allocate investments among the Janus Henderson underlying funds and underlying funds that are not sponsored by the Adviser creates conflicts of interest. For example, investing in Janus Henderson underlying funds could cause the Fund to incur higher fees and may cause the Adviser to receive greater compensation, increase assets under management, or support particular investment strategies. The Adviser, however, is a fiduciary to the Fund and is legally obligated to act in its best interest when selecting underlying funds.
Underlying ETF Risk.Underlying funds that are ETFs (“underlying ETFs”) are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an underlying ETF trades at a premium or discount to its net asset value. Underlying ETFs also involve the risk that an active trading market for an underlying ETF’s shares may not develop or be maintained. Similarly, because the value of underlying
11 | Janus Henderson Global Allocation Fund – Moderate

ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an underlying ETF at the most optimal time, which could adversely affect the Fund’s performance. Trading of an underlying ETF’s shares may be halted by the activation of individual or market-wide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an underlying ETF’s shares may also be halted if (i) the shares are delisted from an exchange without first being listed on another exchange or (ii) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Allocation Risk.The Fund’s ability to achieve its investment objective depends largely upon portfolio management’s allocation of assets among the underlying funds and other securities using Janus Henderson’s proprietary strategic asset allocation and dynamic asset allocation methodologies. You could lose money on your investment in the Fund as a result of these allocations. The Fund will typically invest in a number of different underlying funds; however, to the extent that the Fund invests a significant portion of its assets in a single underlying fund, it will be more sensitive to the risks associated with that fund and any investments in which that fund focuses.
Investment Process Risk.No assurance can be given that the Fund’s investment strategy will be successful under all or any market conditions. Although the proprietary strategic asset allocation and dynamic asset allocation methodologies are designed to achieve the Fund’s investment objective, there is no guarantee that they will achieve the desired results, and there is a risk that they may not be successful in identifying how the Fund’s allocations and security exposures should be adjusted in order to reduce the risk of loss while participating in the upside growth of capital markets.
Risks Through Investing in the Underlying Funds
The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the underlying funds realize their respective investment objectives. Similarly, the Fund’s investment performance is directly related to the investment performance of the underlying funds it holds. The Fund is subject to the risk factors associated with the investments of the underlying funds, and will be affected by such risks in direct proportion to the allocation of its assets among the underlying funds. Therefore, to the extent that the Fund invests significantly in a particular underlying fund, the Fund’s performance would be significantly impacted by the performance of such underlying fund. What follows are the main risks associated with the underlying funds, which, in turn, may be considered to be principal risks of the Fund. These risks are subject to change based on the allocation of the Fund’s assets among the underlying funds.
Market Risk.The value of an underlying fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, an underlying fund’s net asset value may fluctuate and it may be more difficult to value or sell an underlying fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Equity Securities Risk.Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of an underlying fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries in which the issuers of securities the underlying fund holds participate.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in an underlying fund’s income or return potential.
12 | Janus Henderson Global Allocation Fund – Moderate

Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price the underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If an underlying fund’s portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing an underlying fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of an underlying fund’s investments. To the extent that an underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.
Small- and Mid-Sized Companies Risk.Certain of the underlying fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holding are also subject to wider price fluctuations and tend to be less liquid that stock of larger or more established companies, which could have a significant adverse effect on an underlying fund’s returns, especially as market conditions change.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that
13 | Janus Henderson Global Allocation Fund – Moderate

controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which an underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, an underlying fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where an underlying fund has invested a significant amount of its assets may have a greater effect on an underlying fund’s performance than it would in a more geographically diversified portfolio.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Portfolio Management Risk.Certain of the underlying funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and/or research process employed for those underlying funds may fail to produce the intended results. Accordingly, such underlying funds may underperform their respective benchmark indexes or other mutual funds with similar investment objectives.
Passive Investment Risk.Certain of the underlying funds are not actively managed and therefore an underlying fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the underlying fund’s specific benchmark index or the selling of shares is otherwise required upon a rebalancing of the specific benchmark index. Maintaining investments in securities without attempting to take defensive positions, regardless of market conditions or the performance of individual securities, could cause an underlying fund’s return to be lower than if it had employed an active strategy.
Volatility Risk.There is no guarantee that Janus Henderson Adaptive Risk Managed U.S. Equity Fund’s, an underlying fund, strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage.
Counterparty Risk.Certain derivative and “over-the-counter” instruments, such as swaps and forwards, are subject to the risk that the other party to a contract will not fulfill its contractual obligations.
Alternative Investments Allocation Risk.There is a risk that the returns provided by alternative investments may be subject to high volatility and that an underlying fund’s portfolio management’s beliefs about the expected returns, risk and correlation properties of one or more of an underlying fund’s investments may be incorrect. There is also a risk that an underlying fund’s investments will correlate with the performance of stocks and bonds to a greater degree than anticipated. All of these factors
14 | Janus Henderson Global Allocation Fund – Moderate

may negatively affect your investment in the Fund and you could lose money. Investment in the underlying funds also involves derivatives, counterparty, leverage, real estate-related, and commodity-linked investment risks.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. Performance information for each underlying fund is available in its prospectus and/or the most recent annual or semiannual report. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 20, 2024, the Fund changed its investment strategy. Performance prior to June 20, 2024 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
The Fund’s broad-based benchmark index is the MSCI All Country World Index. The Fund’s additional benchmark is the Global Moderate Allocation Index. The indices are described below.
The MSCI All Country World Index is designed to measure equity market performance in global developed and emerging markets.
The Global Moderate Allocation Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the MSCI All Country World Index (60%) and the Bloomberg Global Aggregate Bond Index (40%).
After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which the Fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses the Fund incurs as a result of investing in shares of an underlying fund. The Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any expenses of an underlying fund (acquired fund fees and expenses), shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.14% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including the operating expenses of the underlying funds) are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 100% of the average value of its portfolio.
Principal investment strategies
The Fund seeks to achieve its investment objective by investing in other mutual funds and exchange-traded funds (“ETFs”) (collectively, “underlying funds”) that represent a variety of asset classes and investment styles and provide exposure to issuers that are economically tied to countries throughout the world. Under normal market conditions, the Fund will primarily invest its assets in Janus Henderson underlying funds. The Fund may also invest up to 35% of its assets in underlying funds that
18 | Janus Henderson Global Allocation Fund – Growth

are not sponsored by the Adviser, which portfolio management expects will predominantly pursue passively-managed investment strategies.
The Fund invests in a diversified portfolio of underlying funds and will normally allocate 70%-85% of its investments to underlying funds that provide varying exposure to common stocks of U.S.-based companies and international companies, 10%-25% of its investments to underlying funds that provide varying exposure to fixed-income and money market instruments, and 0%-20% of its investments to underlying funds that provide exposure to alternative investments and alternative investment strategies. The underlying equity funds may invest across a wide range of market capitalizations and segments, including emerging markets, and employ various investment strategies and styles such as growth and value. The underlying fixed-income funds encompass a wide range of fixed-income sectors, including corporate bonds, government securities, mortgage- and asset-backed securities, bank loans, securities that are rated below investment grade, and commercial paper, with varying maturities and duration, credit exposure, and regional exposure. The underlying alternative funds may invest in various alternative strategies, including, but not limited to, commodities, currencies, and hedge fund strategies. Because it invests in other funds, the Fund is considered a “fund of funds.”
Through its investments in underlying funds, the Fund invests in issuers from several different countries. As a result, the Fund normally will have approximately 40% to 65% of its net assets allocated to non-U.S. investments. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the company’s revenues are derived from outside of the United States; or (iii) a majority of the company’s assets are located outside of the United States. The Fund may also have significant exposure to emerging markets.
In managing the Fund, portfolio management employs a proprietary methodology that combines strategic asset allocation and dynamic asset allocation. The strategic asset allocation process is based on an assessment of long-term return, risk, and correlation expectations of various asset classes and is normally applied on an annual basis. The dynamic asset allocation process gives portfolio management the ability to express shorter-term market views and react to market changes by adjusting the Fund’s exposures to the underlying funds and is normally applied on a quarterly basis.
When market conditions dictate a more defensive strategy, the Fund or an underlying fund may temporarily hold cash or invest its assets in temporary investments. In that case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Refer to Appendix A of the Prospectus for a brief description of the investment strategies of each of the currently available Janus Henderson underlying funds. The underlying funds, and the Fund’s investment in any underlying fund, may change at any time without prior notice.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking growth of capital and, to a lesser extent, income. The principal risks associated with investing in the Fund and the underlying funds are set forth below.
Fund-Level Risks
Affiliated Underlying Fund Risk.The Adviser has the authority to select and substitute the underlying funds. The Adviser is subject to conflicts of interest in allocating the Fund’s assets among certain Janus Henderson underlying funds both because the fees payable to it by the Janus Henderson underlying funds differ and because the Adviser is also responsible for managing the Janus Henderson underlying funds. In addition, the Adviser’s authority to allocate investments among the Janus Henderson underlying funds and underlying funds that are not sponsored by the Adviser creates conflicts of interest. For example, investing in Janus Henderson underlying funds could cause the Fund to incur higher fees and may cause the Adviser to receive greater compensation, increase assets under management, or support particular investment strategies. The Adviser, however, is a fiduciary to the Fund and is legally obligated to act in its best interest when selecting underlying funds.
Underlying ETF Risk.Underlying funds that are ETFs (“underlying ETFs”) are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an underlying ETF trades at a premium or discount to its net asset value. Underlying ETFs also involve the risk that an active trading market for an underlying ETF’s shares may not develop or be maintained. Similarly, because the value of underlying
19 | Janus Henderson Global Allocation Fund – Growth

ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an underlying ETF at the most optimal time, which could adversely affect the Fund’s performance. Trading of an underlying ETF’s shares may be halted by the activation of individual or market-wide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an underlying ETF’s shares may also be halted if (i) the shares are delisted from an exchange without first being listed on another exchange or (ii) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Allocation Risk.The Fund’s ability to achieve its investment objective depends largely upon portfolio management’s allocation of assets among the underlying funds and other securities using Janus Henderson’s proprietary strategic asset allocation and dynamic asset allocation methodologies. You could lose money on your investment in the Fund as a result of these allocations. The Fund will typically invest in a number of different underlying funds; however, to the extent that the Fund invests a significant portion of its assets in a single underlying fund, it will be more sensitive to the risks associated with that fund and any investments in which that fund focuses.
Investment Process Risk.No assurance can be given that the Fund’s investment strategy will be successful under all or any market conditions. Although the proprietary strategic asset allocation and dynamic asset allocation methodologies are designed to achieve the Fund’s investment objective, there is no guarantee that they will achieve the desired results, and there is a risk that they may not be successful in identifying how the Fund’s allocations and security exposures should be adjusted in order to reduce the risk of loss while participating in the upside growth of capital markets.
Risks Through Investing in the Underlying Funds
The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the underlying funds realize their respective investment objectives. Similarly, the Fund’s investment performance is directly related to the investment performance of the underlying funds it holds. The Fund is subject to the risk factors associated with the investments of the underlying funds, and will be affected by such risks in direct proportion to the allocation of its assets among the underlying funds. Therefore, to the extent that the Fund invests significantly in a particular underlying fund, the Fund’s performance would be significantly impacted by the performance of such underlying fund. What follows are the main risks associated with the underlying funds, which, in turn, may be considered to be principal risks of the Fund. These risks are subject to change based on the allocation of the Fund’s assets among the underlying funds.
Market Risk.The value of an underlying fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, an underlying fund’s net asset value may fluctuate and it may be more difficult to value or sell an underlying fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Equity Securities Risk.Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of an underlying fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries in which the issuers of securities the underlying fund holds participate.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in an underlying fund’s income or return potential.
20 | Janus Henderson Global Allocation Fund – Growth

Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price the underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If an underlying fund’s portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing an underlying fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of an underlying fund’s investments. To the extent that an underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.
Small- and Mid-Sized Companies Risk.Certain of the underlying fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holding are also subject to wider price fluctuations and tend to be less liquid that stock of larger or more established companies, which could have a significant adverse effect on an underlying fund’s returns, especially as market conditions change.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that
21 | Janus Henderson Global Allocation Fund – Growth

controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which an underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, an underlying fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where an underlying fund has invested a significant amount of its assets may have a greater effect on an underlying fund’s performance than it would in a more geographically diversified portfolio.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Portfolio Management Risk.Certain of the underlying funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and/or research process employed for those underlying funds may fail to produce the intended results. Accordingly, such underlying funds may underperform their respective benchmark indexes or other mutual funds with similar investment objectives.
Passive Investment Risk.Certain of the underlying funds are not actively managed and therefore an underlying fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the underlying fund’s specific benchmark index or the selling of shares is otherwise required upon a rebalancing of the specific benchmark index. Maintaining investments in securities without attempting to take defensive positions, regardless of market conditions or the performance of individual securities, could cause an underlying fund’s return to be lower than if it had employed an active strategy.
Volatility Risk.There is no guarantee that Janus Henderson Adaptive Risk Managed U.S. Equity Fund’s, an underlying fund, strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage.
Counterparty Risk.Certain derivative and “over-the-counter” instruments, such as swaps and forwards, are subject to the risk that the other party to a contract will not fulfill its contractual obligations.
Alternative Investments Allocation Risk.There is a risk that the returns provided by alternative investments may be subject to high volatility and that an underlying fund’s portfolio management’s beliefs about the expected returns, risk and correlation properties of one or more of an underlying fund’s investments may be incorrect. There is also a risk that an underlying fund’s investments will correlate with the performance of stocks and bonds to a greater degree than anticipated. All of these factors
22 | Janus Henderson Global Allocation Fund – Growth

may negatively affect your investment in the Fund and you could lose money. Investment in the underlying funds also involves derivatives, counterparty, leverage, real estate-related, and commodity-linked investment risks.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. Performance information for each underlying fund is available in its prospectus and/or the most recent annual or semiannual report. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 20, 2024, the Fund changed its investment strategy. Performance prior to June 20, 2024 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
The Fund’s broad-based benchmark index is the MSCI All Country World Index. The Fund’s additional benchmark is the Global Growth Allocation Index. The indices are described below.
The MSCI All Country World Index is designed to measure equity market performance in global developed and emerging markets.
The Global Growth Allocation Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the MSCI All Country World Index (80%) and the Bloomberg Global Aggregate Bond Index (20%).
After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

Additional information about the Funds
Fees and expenses
Each Fund, as a shareholder in the underlying funds, will also indirectly bear its pro rata share of the expenses incurred by the underlying funds. The Funds’ returns are net of these expenses. Expenses may be higher or lower depending upon the allocation of the Funds’ assets among the underlying funds and the actual expenses of the underlying funds, including any expenses associated with the underlying funds’ investments in exchange-traded funds.
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services, as well as reimbursement to the Adviser of its out-of-pocket costs for services as administrator. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by each Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses”

The Adviser has contractually agreed to waive and/or reimburse each Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus.
All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
This Prospectus provides information about the Funds, which seek to achieve their investment objectives by investing in underlying funds that provide exposure to equities, fixed-income securities, money market instruments, and alternative investment strategies. Because they invest in other funds, each Fund is considered a “fund of funds.” A fund of funds bears its own direct expenses in addition to bearing a proportionate share of the expenses charged by the underlying funds in which it invests. The Funds are best suited for long-term investors.
This section takes a closer look at the Funds’ principal investment strategies, as well as certain risks of investing in the Funds. Please carefully review the “Risks of the Funds” section of this Prospectus for a discussion of risks associated with certain investment techniques. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout this Prospectus.
Because investors’ risk tolerances, investment goals, investment time horizons, and financial circumstances may be different, each Fund offers a different strategy for pursuing capital growth and income. The allocation to equities, fixed-income securities, money market instruments, and alternative investment strategies in each Fund reflects its greater or lesser emphasis
26 | Janus Investment Fund

on pursuing growth of capital or current income. The following illustrates each Fund’s relative emphasis on seeking growth of capital and seeking income.
The following table indicates each Fund’s normal asset allocation range, which is how each Fund’s investments generally will be allocated among the equity, fixed-income, money market, and alternatives asset classes under normal market conditions.

Each Fund will normally allocate its investments to underlying funds that provide varying exposure to U.S.-based companies of varying market capitalizations, international companies (including those with exposure to emerging markets), bonds and money market instruments, derivatives, currency strategies, and alternative investments. The normal asset allocation ranges, as well as the underlying funds and investments in each underlying fund, may change from time to time without shareholder approval or notice.
Although each Fund can invest in any or all of the Janus Henderson underlying funds described in Appendix A of this Prospectus, as well as in underlying funds not sponsored by the Adviser, it is expected that each Fund will normally invest in only some of the underlying funds at any particular time. Each Fund’s investment in underlying funds that are not sponsored by the Adviser will not exceed 35%. A Fund’s investment in any Janus Henderson underlying fund may exceed 25% of such Fund’s total assets. For information on the Janus Henderson underlying funds currently available for investment by the Funds, including their investment objectives and strategies, see “Investment Objectives and Strategies of the Janus Henderson Underlying Funds” in Appendix A. At the discretion of the Adviser and without prior shareholder notification, the Funds may invest in additional underlying funds established in the future.
Actual holdings percentages may vary due to actual cash flows and changes to the underlying funds’ asset values. In addition, the Funds may reallocate their assets among the underlying funds, including investing a portion or all of its assets in cash equivalents or a money market fund. The Funds and certain underlying funds may purchase unlimited shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles. The Adviser may change the asset class allocations, the underlying funds, an underlying fund’s asset category, or weightings among asset classes or underlying funds without prior notice to shareholders. Information regarding a Fund’s actual allocations to underlying funds is available to shareholders on a periodic basis through the Funds’ annual reports, semiannual reports, and certain other reports filed with the Securities and Exchange Commission (the “SEC”), as well as at janushenderson.com/allfunds. Please refer to “Availability of Portfolio Holdings Information” in this Prospectus to learn how to access the most recent allocation information.
The proprietary methodology employed by portfolio management normally combines the strategic asset allocation process, on an annual basis, and the dynamic asset allocation process, on a quarterly basis.
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
Unless otherwise stated, the following additional investment strategies and general policies apply to the Funds and the underlying funds. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent.
27 | Janus Investment Fund

Cash Position
A Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
Portfolio Turnover
The Funds normally seek long-term investment, although the Funds may sell shares of the underlying funds regardless of how long they have been held. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to shareholder purchases and redemptions), the nature of a Fund’s investments, and the investment style of portfolio management. Changes are normally made in a Fund’s holdings whenever portfolio management believes such changes are desirable. Portfolio turnover rates are generally not a factor in making decisions regarding asset allocations among the underlying funds. The Funds’ transactions in Janus Henderson underlying mutual funds do not entail brokerage commissions, but may result in taxable capital gains. The Funds’ transactions in the underlying ETFs may incur brokerage commissions. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
Risks of the Funds
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The allocation of each Fund’s assets to underlying funds may not be successful in achieving the Fund’s investment objective. There is a risk that you may experience lower returns by investing in a Fund instead of investing directly in an underlying fund. A Fund’s returns are directly related to the aggregate performance and expenses of the underlying funds in which it invests. Certain of the underlying funds in which a Fund may invest have operated for shorter time periods and therefore have limited investment results, smaller asset bases, and estimated expense ratios. Investments by a Fund in such an underlying fund may increase the indirect expenses paid by the Fund and may result in the Fund not achieving its investment objective.
There is additional risk for the Funds with respect to aggregation of holdings of underlying funds. The aggregation of holdings of underlying funds may result in a Fund indirectly having concentrated assets in a particular industry, geographical sector, or single company. Such indirect concentrated holdings may have the effect of increasing the volatility of the Fund’s returns. The Funds do not control the investments of the underlying funds, or any indirect concentration that occurs as a result of the underlying funds following their investment objectives.
The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies employed for the Funds may fail to produce the intended results. A Fund may underperform its benchmark index or other mutual funds with similar investment objectives.
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, because the Adviser manages the Funds and the Janus Henderson underlying funds, it is subject to certain potential conflicts of interest when allocating the assets of the Funds among Janus Henderson underlying funds. Portfolio management, officers, and Trustees of the Funds may also serve in the same capacity as portfolio management, officers, and Trustees of the Janus Henderson underlying funds. Conflicts may arise as portfolio management, officers, and Trustees seek to fulfill their fiduciary responsibilities to the Funds and the Janus Henderson underlying funds.
Purchases and redemptions of an underlying fund by a Fund due to reallocations or rebalancing may result in an underlying fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the realization of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Fund
28 | Janus Investment Fund

purchases, redeems, or owns a substantial portion of the underlying fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.
Each Fund invests in underlying funds that may invest substantially all of their assets in common stocks. The main risk associated with investing in those funds is the risk that the value of the stocks they hold might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. If this occurs, an underlying fund’s share price may also decrease.
Each Fund also invests in underlying funds that may invest substantially all of their assets in fixed-income securities or income-generating securities. Investing in this type of underlying fund may expose a Fund to risks such as credit risk and interest rate fluctuations.
A Fund’s performance may also be affected by risks of certain types of investments by the underlying funds. An underlying fund’s performance may also be significantly affected, positively or negatively, by portfolio management’s use of certain types of investments, such as foreign (non-U.S.) securities, derivative investments, ETFs, non-investment grade bonds (also known as “junk” bonds), initial public offerings, or securities of companies with relatively small market capitalizations. Note that portfolio management’s use of such investments may have a magnified performance impact on an underlying fund with a small asset base. In addition, there is a risk that portfolio management may not have the ability to look through to an underlying fund’s investments in connection with monitoring a Fund’s exposure across different asset classes.
The following information is intended to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investment allocation. The greater a Fund’s allocation to an underlying fund or investment, the greater the Fund’s exposure to the risks associated with that underlying fund or investment. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Authorized Participant Risk.An underlying ETF may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the underlying ETF’s distributor may engage in creation or redemption transactions directly with the underlying ETF. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the underlying ETF’s shares will be established or maintained. This risk may be heightened to the extent that the securities held by an underlying ETF are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to net asset value and possibly face delisting.
Collateral Risk.With respect to collateral received in repurchase transactions or other investments, an underlying fund may have significant exposure to financial services, mortgage markets, and government agencies not secured by the full faith and credit of the United States. Such exposure, depending on market conditions, could have a negative impact on an underlying fund, including minimizing the value of any collateral.
Counterparty Risk.Underlying fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the underlying fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to an underlying fund. An underlying fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. An underlying fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the underlying fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, an underlying fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of forwards, swaps, futures, and options). To the extent that an underlying fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.Through a Fund’s investments in underlying funds holding fixed-income securities, the Fund is subject to the risks associated with the credit quality of the issuers of those fixed-income securities. Credit quality measures the
29 | Janus Investment Fund

likelihood that the issuer or borrower will meet its obligations on a bond. One of the fundamental risks for an underlying fund is credit risk, which is the risk that an issuer will be unable to make principal and interest payments when due, or default on its obligations. Higher credit risk may negatively impact an underlying fund’s returns and yield.
Many fixed-income securities receive credit ratings from services such as Standard & Poor’s Rating Services (“Standard & Poor’s”), Fitch, Inc. (“Fitch”), and Moody’s Investors Service, Inc. (“Moody’s”). These services assign ratings to securities by assessing the likelihood of issuer default. The lower a bond issue is rated by an agency, the more credit risk it is considered to represent. Lower rated instruments and securities generally pay interest at a higher rate to compensate for the associated greater risk. Interest rates can fluctuate in response to economic or market conditions, which can result in a fluctuation in the price of a security and impact an underlying fund’s return and yield. If a security has not received a rating, an underlying fund must rely upon an adviser’s credit assessment, which if incorrect can also impact the underlying fund’s returns and yield. Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by an underlying fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent an underlying fund enters into short derivative positions, the underlying fund may be exposed to risks similar to those associated with short sales, including the risk that the underlying fund’s losses are theoretically unlimited.
Emerging Markets Risk.An underlying fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” To the extent that an underlying fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for an underlying fund to obtain or to enforce a judgment against the issuers of such securities. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the underlying fund’s investments. To the extent that an underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the underlying fund’s performance. An underlying fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets. Additionally, foreign and emerging market risks, including but not limited to price controls, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, nationalization, and restrictions on repatriation of assets may be heightened to the extent an underlying fund invests in Chinese or other local market securities.
Emerging market countries in which an underlying fund may invest include frontier market countries, which generally have smaller economies and even less developed capital markets than traditional developing markets, and as a result, the risks of investing in developing market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values
30 | Janus Investment Fund

and other protectionist measures imposed or negotiated by other countries; and the relatively new and unsettled securities laws in many frontier market countries.
Equity Securities Risk.The values of equity securities, such as common stocks and preferred stocks, may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than fixed-income securities. These risks are generally magnified in the case of equity investments in distressed companies.
ESG Integration and Investment Risk.Certain underlying funds consider environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) as part of their investment process. There is a risk that considering ESG Factors as part of an underlying fund’s investment process may fail to produce the intended results or that an underlying fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While an underlying fund’s portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which an underlying fund’s portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require an underlying fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
Certain underlying funds have a sustainable or ESG-related strategy, or may employ exclusionary criteria to avoid investing in certain industries, activities, or assets considered by portfolio management to have a negative impact on society or the environment. These underlying funds are subject to similar risks as those underlying funds that consider ESG factors as part of their investment process.
European Investments Risk.Exposure to investments in European countries may expose an underlying fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. An underlying fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.
Exchange-Traded Funds Risk.ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When an underlying fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in an underlying fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds.
Exchange Listing.Shares of an underlying ETF are listed for trading on an exchange; however, there can be no guarantee that an active trading market for such shares will continue or that the underlying ETF’s shares will continue to meet the listing or trading requirements of any exchange.
Fixed-Income Securities Risk.Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that the value of such securities will generally decline as prevailing interest rates rise, which may cause an underlying fund’s net asset value to likewise
31 | Janus Investment Fund

decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities and durations tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates and are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. However, calculations of maturity and duration may be based on estimates and may not reliably predict a security’s price sensitivity to changes in interest rates. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. Investments in fixed-income securities with very low or negative interest rates may diminish an underlying fund’s yield and performance.
Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. In addition, there is prepayment risk, which is the risk that during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in the underlying fund’s income or return potential. Fixed-income securities may also be subject to valuation risk and liquidity risk. Valuation risk is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer of the security. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price an underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk. To the extent an underlying fund invests in fixed-income securities in a particular industry or economic sector, its share values may fluctuate in response to events affecting that industry or sector. Securities underlying mortgage- and asset-backed securities, which may include subprime mortgages, also may be subject to a higher degree of credit risk, valuation risk, and liquidity risk. To the extent that an underlying fund invests in derivatives tied to fixed-income securities, such underlying fund may be more substantially exposed to these risks than an underlying fund that does not invest in such derivatives. The market for certain fixed-income securities may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Similarly, the amount of assets deemed illiquid remaining within such underlying fund may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the underlying fund and the Fund.
Floating Rate Obligations Risk.Certain underlying funds may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Unexpected changes in the interest rates on floating rate obligations could result in lower income to an underlying fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, an underlying fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Foreign Exposure Risk.Certain underlying funds may invest in foreign equity and/or debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in
32 | Janus Investment Fund

domestic securities because an underlying fund’s performance may depend on factors other than the performance of a particular company. These factors include:
Currency Risk.As long as an underlying fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When an underlying fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Foreign Market Risk.Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on an underlying fund. Such factors may hinder an underlying fund’s ability to buy and sell emerging market securities in a timely manner, affecting the underlying fund’s investment strategies and potentially affecting the value of such underlying fund.
Geographic Concentration Risk.To the extent that an underlying fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on an underlying fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on an underlying fund’s performance.
Political and Economic Risk.Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the U.S. Government on other countries or persons or issuers operating in such countries could restrict an underlying fund’s ability to buy affected securities or force an underlying fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, an underlying fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of an underlying fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
Regulatory Risk.There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
Transaction Costs.Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are bonds rated below investment grade by the primary rating agencies, such as BB+ or lower by Standard & Poor’s and Fitch, or Ba1 or lower by Moody’s, or is an unrated bond of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In
33 | Janus Investment Fund

addition, the junk bond market can experience sudden and sharp price swings. Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Industry and Sector Risk.Although the Funds do not concentrate their investments in specific industries or economic sectors, certain underlying funds may invest, or may have a significant portion of their assets invested in, securities of companies conducting similar business or businesses within the same economic sector. Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. An underlying fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase that underlying fund’s exposure to industry and sector risk.
Inflation Risk.Inflation risk is the risk that the value of certain assets or real income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the present value of an underlying fund’s assets and distributions may decline. This risk may be elevated in a low interest rate environment.
Inflation-Linked Investments Risk.Inflation-linked bonds (including Treasury Inflation-Protected Securities, also known as TIPS), and other inflation-linked securities normally will decline in price when real interest rates rise. In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, inflation-linked bonds may experience greater losses than other fixed-income securities with similar durations. Except for an underlying fund’s investments in TIPS, which are guaranteed as to principal by the U.S. Treasury, the inflation-adjusted principal value or maturity amount of inflation-linked bonds repaid at maturity may be less than the original principal. Because of their inflation-linked adjustment feature, inflation-linked bonds typically have lower yields than conventional fixed-rate securities. In the event of deflation, where prices decline over time, the principal and income of inflation-linked bonds will likely decline, resulting in losses to an underlying fund.
Initial Public Offering and Secondary Offering Risk.A Fund may invest in underlying funds that may purchase shares issued as part of, or a short period after, a company’s initial public offering (“IPO”), and may at times dispose of those shares shortly after their acquisition. An IPO is the first sale of stock by a private company to the public. IPOs are often issued by smaller, younger companies seeking the capital to expand, but can also be done by large privately-owned companies looking to become publicly traded. To the extent a Fund is invested in underlying funds that purchase shares issued in IPOs, the Fund is exposed to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. Attractive IPOs are often oversubscribed and may not be available to the underlying funds in which a Fund invests, or may be available only in very limited quantities. The market for IPO issuers has been volatile, and share prices of newly public companies have fluctuated up and down significantly over short periods of time. There can be no assurance that the underlying funds will identify favorable IPO investment opportunities. In addition, under certain market conditions, a relatively small number of companies may issue securities in IPOs. Similarly, as the number of underlying funds to which IPO securities are allocated increases, the number of securities issued to any one underlying fund may decrease. In addition, as a Fund or underlying fund increases in size, the impact of IPOs on the Fund’s performance will generally decrease.
A Fund may invest in underlying funds that may purchase shares in secondary offerings. Secondary offerings may expose the underlying fund to some of the risks of IPOs. Participation in secondary offerings may have a magnified impact on the performance of an underlying fund to the extent that it has a small asset base and the underlying fund may not experience similar performance as its assets grow. Secondary offering shares frequently are volatile in price. As a result, an underlying fund may hold secondary offering shares for a very short period of time. This may increase the portfolio turnover rate of the underlying fund and may lead to increased expenses for the underlying fund, such as commissions and transaction costs. In addition, secondary offering shares can experience an immediate drop in value if the demand for the securities does not continue to support the offering price.
Interest Rate Risk.Generally, a fixed-income security will increase in value when prevailing interest rates fall and decrease in value when prevailing interest rates rise. Longer-term securities are generally more sensitive to interest rate changes than shorter-term securities, but they generally offer higher yields to compensate investors for the associated risks. High-yield bond prices and floating rate debt security prices are generally less directly responsive to interest rate changes than investment grade issues or comparable fixed rate securities, and may not always follow this pattern.
34 | Janus Investment Fund

Leverage Risk.Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose an underlying fund to greater risk and increase its costs. The use of leverage may cause an underlying fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act of 1940, as amended, and the rules thereunder. Increases and decreases in the value of an underlying fund’s portfolio will be magnified when the underlying fund uses leverage.
Liquidity Risk.An underlying fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. An underlying fund may also make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, an underlying fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect an underlying fund’s value or prevent such underlying fund from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that an underlying fund invests in restricted securities that are deemed to be illiquid investments.
Loan Risk.Certain underlying funds may invest in various commercial loans, including bank loans, bridge loans, debtor-in-possession (“DIP”) loans, mezzanine loans, and other fixed and floating rate loans. The risks of such investments vary, depending on the type of loans underlying the investments, as described below.
Bank Loan Risk.Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. The bank loans in which an underlying fund may invest may be denominated in U.S. or non-U.S. currencies, including the euro. An underlying fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged or in bankruptcy proceedings. Participation interests and assignments involve credit, interest rate, and liquidity risk. Some participation interests and assignments may not be considered “securities,” and purchasers, such as an underlying fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Additionally, because the Adviser, in the course of investing an underlying fund’s assets in loans, may have access to material non-public information regarding the borrower, the ability of an underlying fund to purchase or sell publicly-traded securities of such borrowers may be restricted. In addition, to the extent an underlying fund invests in non-U.S. bank loan investments, those investments also are subject to the risks of foreign investment, including those described under “European Investments Risk.”
Bridge Loan Risk.Bridge loans are short-term loan arrangements typically made by a borrower in anticipation of receiving intermediate-term or long-term permanent financing. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan increases the longer the loan remains outstanding.
DIP Loan Risk. DIP loans are issued in connection with restructuring and refinancing transactions. DIP loans are loans to a debtor-in-possession in a proceeding under the U.S. bankruptcy code that have been approved by the bankruptcy court. In addition to the risks associated with bank loans, an underlying fund’s investments in bridge loans may subject a Fund to certain risks, including the risk that a borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. An underlying fund’s investments in DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets.
Mezzanine Loan Risk.Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations.
Market Risk. The value of an underlying fund’s portfolio may decrease if the value of one or more issuers in the underlying fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities
35 | Janus Investment Fund

prices, or if the market favors different types of securities than the types of securities in which the underlying fund invests. If the value of the underlying fund’s portfolio decreases, an underlying fund’s net asset value will also decrease, resulting in a decrease in a Fund’s net asset value, which means if you sell your shares in the Fund, you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Money Market Fund Investment Risk.An underlying fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, an underlying fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and an underlying fund may lose money. To the extent an underlying fund transacts in instruments such as derivatives, such underlying fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from such underlying fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share net asset value at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable net asset value could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their net asset values. Certain money market funds have in the past failed to maintain stable net asset values, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the SEC require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s net asset value per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating net asset value requirements. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund.
Recently adopted amendments to Rule 2a-7 also require certain money market funds, excluding Government Money Market Funds and Retail Money Market Funds, to impose mandatory liquidity fees when a fund experiences net redemptions that exceed 5% of net assets, unless the fund’s liquidity costs are de minimis (i.e., less than 1 basis point).
There can be no assurance that an underlying fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
In addition to the fees and expenses that an underlying fund directly bears, an underlying fund indirectly bears the fees and expenses of any money market fund in which it invests.
Mortgage- and Asset-Backed Securities Risk.Rising interest rates tend to extend the duration of, or reduce the rate of prepayments on, both commercial mortgage-backed securities (“CMBS”) and residential mortgage-backed securities (“RMBS”), making them more sensitive to changes in interest rates (“extension risk”). As a result, in a period of rising interest rates, the price of mortgage-backed securities may fall, causing an underlying fund that holds mortgage-backed securities to exhibit
36 | Janus Investment Fund

additional volatility. Mortgage-backed securities are also subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce an underlying fund’s returns because the underlying fund will have to reinvest that money at lower prevailing interest rates. Investments in certain mortgage-backed securities, including those comprised of subprime mortgages, may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities. Additionally, although mortgage-backed securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that guarantors or insurers will meet their obligations.
CMBS are subject to certain other risks. The market for CMBS developed more recently than that for RMBS and is relatively small in terms of outstanding principal amount of issues compared to the RMBS market. CMBS are also subject to risks associated with a lack of standardized terms, shorter maturities than residential mortgage loans, and payment of all or substantially all of the principal at maturity, rather than regular amortization of principal. Moreover, the type and use of a particular commercial property may add to the risk of CMBS investments. Adverse changes in economic conditions and circumstances are more likely to have an adverse impact on mortgage-backed securities secured by loans on commercial properties than on those secured by residential properties.
Similarly, the value of an underlying fund’s investments in asset-backed securities may be adversely affected by changes in interest rates, factors concerning the interests in and structure of the issuer or originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds, or other credit or liquidity enhancements, and/or the market’s assessment of the quality of the underlying assets. Generally, the originating bank or credit provider is neither the obligor nor the guarantor of the security, and interest and principal payments ultimately depend upon payment of the underlying loans by individuals. An underlying fund could incur a loss if the underlying loans are not paid. In addition, most asset-backed securities are subject to prepayment risk in a declining interest rate environment. The impact of prepayments on the value of asset-backed securities may be difficult to predict and may result in greater volatility. Rising interest rates tend to extend the duration of asset-backed securities, making them more volatile and sensitive to changing interest rates.
Nondiversification Risk.Certain underlying funds may be classified as nondiversified under the Investment Company Act of 1940, as amended. As a result, an increase or decrease in the value of a single security held by an underlying fund may have a greater impact on the underlying fund’s net asset value and total return. Being nondiversified may also make an underlying fund more susceptible to financial, economic, political, or other developments that may impact a security. Although an underlying fund may satisfy the requirements for a diversified fund, its nondiversified classification gives the underlying fund’s portfolio management more flexibility to hold larger positions in more securities than an underlying fund that is classified as diversified.
Portfolio Turnover Risk.Increased portfolio turnover of underlying funds may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on the underlying fund’s performance.
Private Placements and Other Exempt Securities Risk.Investments in private placements and other securities exempt from certain registration requirements could decrease an underlying fund’s liquidity profile or prevent an underlying fund from disposing of them promptly at advantageous prices. Private placements and other securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. Transaction costs may be higher for these securities, and an underlying fund may get only limited information about the issuer of a private placement or other security exempt from certain registration requirements.
REIT and Real Estate-Related Securities Risk.To the extent that an underlying fund holds real estate investment trusts (“REITs”) and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under
37 | Janus Investment Fund

mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which an underlying fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. An underlying fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of an underlying fund’s expenses. The value of investments in real estate operating companies (“REOCs”) will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for an underlying fund, including significantly reducing the return to the underlying fund on its investment in such company.
Secondary Market Trading Risk.The net asset value of an underlying ETF’s shares will generally fluctuate with changes in the market value of the underlying ETF’s securities holdings. However, shares of an underlying ETF trade on a national securities exchange at prices above or below their most recent net asset value. The “market price” for an underlying ETF’s fluctuates continuously throughout the national securities exchange’s trading day based on supply and demand of the underlying ETF’s shares. The market price of an underlying ETF’s shares may not track an underlying ETF’s net asset value, which is only calculated at the end of each business day.
A potential investor in an underlying ETF will likely also incur the cost of the “spread” (the difference between the bid price and the ask price for a share of the underlying ETF). The spread varies over time for shares of an underlying ETF. The cost is generally smaller for underlying ETFs with significant daily trading volumes and larger for underlying ETFs with smaller daily trading volumes.
Additionally, during a “flash crash,” the market price of an underlying ETF’s shares may decline suddenly and significantly, resulting in underlying ETF shares trading at a substantial discount to its net asset value. Such a decline may not reflect the performance of the portfolio securities held by the underlying ETF. Flash crashes may also cause APs and other market makers to limit or cease trading in an underlying ETF’s shares, which may result in a further increase in the variance between market prices of the underlying ETF’s shares and the underlying ETF’s shares’ net asset value. Shareholders could suffer significant losses to the extent that they sell Fund shares during a flash crash.
Securities Lending Risk.An underlying fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When an underlying fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The underlying fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, the underlying fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the underlying fund may experience delays and costs in recovering the security or gaining access to the collateral provided to collateralize the loan. If the underlying fund is unable to recover a security on loan, the underlying fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the underlying fund. With respect to Janus Henderson underlying funds, the Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Short Sales Risk.Short sales are speculative transactions and involve special risks, including a greater reliance on the ability to accurately anticipate the future value of a security. An underlying fund will suffer a loss if it sells a security short and the value of the security rises rather than falls. An underlying fund’s losses are potentially unlimited in a short sale transaction. The use of short sales may also cause an underlying fund to have higher expenses than those of other underlying funds. In addition, due to the investment process of long and short positions, an underlying fund may be subject to additional
38 | Janus Investment Fund

transaction costs that may lower the underlying fund’s returns. An underlying fund’s use of short sales may also have a leveraging effect on the underlying fund’s portfolio and may increase losses and volatility of returns.
Sovereign Debt Risk.Certain underlying funds may invest in U.S. and non-U.S. government debt securities (“sovereign debt”). Investments in sovereign debt, especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. An underlying fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the underlying fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Swap Agreements Risk.Certain underlying funds may utilize swap agreements including, but not limited to, credit default swaps, equity swaps, inflation index swaps, interest rate and currency swaps, total return swaps (including fixed-income total return swaps), and swaps on exchange-traded funds, as a means to gain exposure to certain companies or countries, and/or to “hedge” or protect their portfolios from adverse movements in securities prices, the rate of inflation, or interest rates. Swaps may also be used for capital appreciation. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to the underlying fund. If the other party to a swap defaults, the underlying fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If an underlying fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the underlying fund and reduce the underlying fund’s total return. Various types of swaps such as credit default, equity, interest rate, and total return are described in the “Glossary of Investment Terms.”
TBA Commitments Risk.Certain underlying funds may enter into “to be announced” or “TBA” commitments. Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the underlying fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to an underlying fund may be less favorable than expected. There is a risk that the security that an underlying fund buys will lose value between the purchase and settlement dates. When an underlying fund sells a TBA security prior to settlement, it does not participate in future gains or losses with respect to the security. An underlying fund is generally not required to pay for the TBA security until the settlement date and, as a result, if the underlying fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
Variable Interest Entities (“VIEs”) Risk.In seeking exposure to Chinese issuers, an underlying fund may invest in VIE structures, which in addition to the risks listed under “Foreign Exposure Risk” and “Emerging Markets Risk,” present additional complexity and risks that may not be present in other organizational structures. VIE structures enable foreign investors, such as an underlying fund, to obtain exposure to a Chinese operating company through a contractual agreement without having equity ownership of such company. The Chinese government could determine at any time, and without notice, that the agreements establishing the VIE structure do not comply with Chinese law and regulations, which could result in potential penalties, revocation of business and operating licenses, or forfeiture of ownership interests. Additionally, because VIEs operate using contractual arrangements rather than having equity ownership, foreign investors do not have rights of direct equity owners including rights to residual profits or control over management.
Volatility Risk.Portfolio management of Janus Henderson Adaptive Risk Managed U.S. Equity Fund, an underlying fund, uses a proprietary methodology that seeks to avoid issuers whose upside volatilities are perceived to be lower and whose downside volatilities are perceived to be higher. There is no guarantee that the underlying fund’s strategy to minimize
39 | Janus Investment Fund

volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.

Management of the Funds
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Funds and certain underlying funds (the “Janus Henderson underlying funds”). The Adviser is responsible for the day-to-day management of the Funds’ investment portfolios, as well as the investment portfolios of the Janus Henderson underlying funds, and furnishes continuous advice and recommendations concerning the Funds’ investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Funds.
In addition, the Adviser utilizes a personnel-sharing arrangement with its foreign (non-U.S.) affiliate, Janus Henderson Investors UK Limited (“JHIUKL”), pursuant to which one or more Janus Henderson employees, acting for JHIUKL, may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for JHIUKL, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to the Funds on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of a Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate a Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that a Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to a Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for a Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The terms of the exemptive order that are discussed above may also apply to the Janus Henderson underlying funds because they are managed by the Adviser. Refer to such underlying funds’ prospectuses for additional detail.
The Adviser furnishes certain administration, compliance, and accounting services to the Funds, including providing office space for the Funds and providing personnel to serve as officers to the Funds. The Adviser generally pays the salaries, fees, and expenses of Fund officers with respect to services provided to the Funds, although some expenses related to compensation payable to the Funds’ Chief Compliance Officer and compliance staff are shared with the Funds.
Management expenses
Each Fund pays the Adviser an investment advisory fee and incurs expenses, including administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay. The Adviser also receives an investment advisory fee for managing the Janus Henderson underlying funds. Refer to such underlying funds’ prospectuses for specific information about investment advisory fees.

For the fiscal year ended June 30, 2024, the Fund did not pay any compensation to the Adviser (net of fee waivers) because the Fund’s fee waiver exceeded the investment advisory fee.
A discussion regarding the basis for the Trustees’ approval of the Funds’ investment advisory agreements is included in each Fund’s semiannual report (for the period ended December 31, 2023) and in the Funds’ financial statements (for the period ended June 30, 2024, and moving forward). You can request the Funds’ semiannual reports or financial statements (as they become available), free of charge, by contacting a Janus Henderson representative at 1-800-525-3713. This information is also available, free of charge, at janushenderson.com/reports.
Expense Limitations
The Adviser has contractually agreed to waive the advisory fee payable by each Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding any expenses of an underlying fund (acquired fund fees and expenses), shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below. The Adviser has agreed to continue each waiver for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. For information about how the expense limit affects the total expenses of each Fund, if applicable, see the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus.

Other information
CLOSED FUND POLICIES
A Fund may limit sales of its Shares to new investors. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Funds
The Funds are distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Funds, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within a single Fund. Distributions by the underlying funds and changes in asset allocations may result in taxable distributions of ordinary income or capital gains.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well.
How Distributions Affect a Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus Henderson representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
Distribution Options
When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janushenderson.com/individual, by calling a Janus Henderson representative, or by writing to the Funds at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Funds offer the following options:
Reinvestment Option.You may reinvest your income dividends and capital gains distributions in additional shares.
Cash Option.You may receive your income dividends and capital gains distributions in cash.
Reinvest and Cash Option.You may receive either your income dividends or capital gains distributions in cash and reinvest the other in additional shares.

The Funds reserve the right to reinvest uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Shareholder Services and Account Policies.”
TAXES
As with any investment, you should consider the tax consequences of investing in the Funds. The following is a general discussion of certain federal income tax consequences of investing in the Funds. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of an underlying fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, an underlying fund that invests in REITs is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than an underlying fund that does not invest in REITs.
Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of a Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Funds may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), a Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in
46 | Janus Investment Fund

the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, the Janus Henderson funds will report cost basis information to you and to the IRS. Each Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If a Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in partnerships, it may be subject to state tax liabilities.

All states have repealed UGMA statutes, enacting UTMA statutes in their place. Existing UGMA accounts established before the date of repeal are grandfathered using the original UGMA age of termination.
Minimum Investment Requirements
Due to the proportionately higher costs of maintaining small accounts, the Funds reserve the right to deduct an annual $25 minimum balance fee per Fund account (paid to the Transfer Agent) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You will receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.
Available Incentive Programs
Bonus Program for Taxable Account Purchases and Tax-Advantaged Account Transfers/Rollovers
Through the Transfer Agent’s Bonus Program, the Transfer Agent will pay a bonus of up to $2,500 to you for making certain eligible purchases of Fund shares in taxable accounts or transfers/rollovers from a non-Janus Henderson fund account into a Janus Henderson fund tax-advantaged account. The Bonus Program is valid with an eligible purchase or transfer/rollover of $20,000 or more. If you meet the eligibility requirements for the Bonus Program and enroll in it, the Transfer Agent will deposit a bonus payment into your Fund account within approximately 30 days after the deposit of eligible funds in good order and receipt of a signed contract governing the Bonus Program. An investor must keep the eligible purchase in the account for a period of 360 calendar days in order to retain the bonus payment. Any sale of the qualifying purchase amount (in whole or in part), transfer, or closure of the account within the 360 calendar day period may result in forfeiture of the bonus payment. Any decline in an account’s value due solely to market value fluctuations will not result in the forfeiture of the bonus payment. Only taxable account purchases or transfers/rollovers to tax-advantaged accounts that are made on or after January 1, 2024 through December 31, 2024 are eligible for a bonus payment. The eligible period for the Bonus Program may be extended beyond this time frame at the sole discretion of the Transfer Agent. Before enrolling in the Bonus Program, consult with your tax advisor about the appropriate tax treatment for the bonus offer and any tax implications associated with the receipt of a bonus payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke this Bonus Program at any time without advance notice.
You can request more information about the Transfer Agent’s Bonus Program and eligibility requirements for taxable accounts by contacting a Janus Henderson representative at 1-800-525-3713 or by visiting www.janushenderson.com/bonus. You can request more information about the Bonus Program for tax-advantaged account transfers/rollovers by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Contribution Match Payments
Investors that transfer/rollover assets from a non-Janus Henderson fund account into a tax-advantaged account are also eligible for the Transfer Agent’s Contribution Match Program. To receive a Transfer Agent’s Contribution Match payment, (i) the value of your tax-advantaged account must remain equal to or greater than the value of the eligible transfer/rollover (but not including any losses due solely to market value fluctuations) for 12 months following the receipt of your transfer/rollover in good order and receipt of a signed contract governing the Contribution Match Program, and (ii) you must provide instructions to the Transfer Agent on how to invest these payments. The Transfer Agent’s Contribution Match payments will commence at the end of the first quarter in 2025 following an eligible contribution during the first quarter of 2025 into a Janus Henderson fund tax-advantaged account. The eligible period for the Transfer Agent’s Contribution Match payments may be extended beyond this time frame at the sole discretion of the Transfer Agent. The Transfer Agent will match a percentage of these contributions based on the aggregate value of eligible 2024 rollover or asset transfer amounts, and provide a matching contribution in an amount up to ten percent of your contribution. Before enrolling in the Contribution Match Program, consult with your tax advisor about the appropriate tax treatment for the Transfer Agent’s Contribution Match payments and any tax implications associated with the receipt of a Contribution Match payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Contribution Match Program at any time without advance notice.

Ready. Invest. Go. Program
New investors creating a new Janus Henderson direct account are eligible to participate in the Transfer Agent’s Ready. Invest. Go. Program. After the new investor has completed the required Ready. Invest. Go. Program Contract, the Transfer Agent will fund the $100 initial investment required for new investors, provided that new investors enroll in Janus Henderson’s automatic investment program in an amount equal to at least $50 per month. New investors will forfeit the $100 bonus contributed by the Transfer Agent if their account is closed or if their automatic monthly investment program payment is terminated within two years from the date the initial investment was made. Investor-initiated amounts outside of the initial investment are redeemable at any time at net asset value. Before enrolling in the Ready. Invest. Go. Program, new investors should consult with their tax advisor about the appropriate tax treatment for participating in the Ready. Invest. Go. Program and any tax implications associated with the receipt of the $100 initial investment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Ready. Invest. Go. Program at any time without advance notice.

Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The value of a Fund’s investment in an underlying mutual fund is based upon the NAV of such underlying mutual fund. The value of a Fund’s investment in an underlying ETF is generally based on the closing prices of such underlying ETF at the applicable exchange. A Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which a Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by an underlying fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.
52 | Janus Investment Fund

All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after a request is received in good order by a Fund or its agents.
Janus Henderson underlying fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing underlying fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security of a non-money market underlying fund may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of an underlying fund’s portfolio securities and the reflection of such change in a Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While underlying funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in underlying funds which do not invest in foreign securities, for example, when trading in a security held by an underlying fund is halted and does not resume prior to the time the underlying fund calculates its NAV (referred to as “stale pricing”). Underlying funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of an underlying fund may dilute the NAV of that underlying fund, which negatively impacts long-term shareholders of the underlying fund. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
Policies in Relation to Transactions
All requests, including but not limited to, exchanges between a Fund and other Janus Henderson funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus Henderson’s P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving underlying funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase.

Administrative services fees
The Funds pay an annual administrative services fee based on the average daily net assets of Class D Shares, as detailed below.
Average Daily Net Assets of Class D Shares of the Janus Henderson funds
Administrative Services Fee
Under $40 billion
0.12%
$40 billion - $49.9 billion
0.10%
Over $49.9 billion
0.08%
These administrative services fees are paid by Class D Shares of each Fund. The Transfer Agent provides or arranges for the provision of shareholder services including, but not limited to, recordkeeping, accounting, answering inquiries regarding accounts, transaction processing, transaction confirmations, and the mailing of prospectuses and shareholder reports.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary and when considering which share class of a fund is most appropriate.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when
54 | Janus Investment Fund

evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you.
Paying for shares

All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted non-U.S. bank.
Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.
When purchasing Shares through the Automatic Investment Program, your automatic investment selection(s) will generally be active within three days following receipt of your authorization for the date and amount you specify. If no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. If the balance in the Janus Henderson fund account you are buying into falls to zero as the result of a redemption, exchange, or minimum balance fee, your Automatic Investment Program will be discontinued.
We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Funds by submitting good funds via another method accepted by the Funds (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.
Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”
If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as applicable, will be invested in Janus Henderson Government Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus Henderson to (i) buy shares of another Janus Henderson fund or (ii) sell shares of Janus Henderson Government Money Market Fund and return the proceeds (including any dividends earned) to you, Janus Henderson will treat your inaction as approval of the purchase of Janus Henderson Government Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus Henderson for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Henderson Government Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Henderson Government Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will be automatically exchanged from Janus Henderson Government Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”
For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.
If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and any losses incurred by a Fund as a result. A Fund may redeem shares held in your account to cover any losses it incurs if your purchase is cancelled.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), the Adviser is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth,
55 | Janus Investment Fund

Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, the Adviser may temporarily limit additional share purchases. In addition, the Adviser may close an account if it is unable to verify a shareholder’s identity. Please contact a Janus Henderson representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
The Funds have also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Funds are required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.
Exchanges
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Please note the following when exchanging Shares:
An exchange represents the redemption (or sale) of shares from one Fund and the purchase of shares of another Fund, which may produce a taxable gain or loss in a non-retirement account.
You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. A Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.
New regular Janus Henderson fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus Henderson fund account you are exchanging from is less than $2,500 ($100 for new regular Fund accounts with an automatic investment program of $50 per month). (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus Henderson fund account you are exchanging from is less than the stated minimum, you must exchange the entire balance. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
New Janus Henderson fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you
56 | Janus Investment Fund

may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
Exchanges between existing Janus Henderson fund accounts must meet the $50 subsequent investment requirement.
For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus Henderson fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. Different restrictions may apply if you invest through an intermediary.
Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
With certain exceptions, exchanges between Janus Henderson fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus Henderson fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.

Payment of redemption proceeds
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Funds.
By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.
Next Day Wire Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.
ACH (Automated Clearing House) Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on or about the next bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.
By Check – Redemption proceeds will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.
By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus Henderson fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.
The Funds typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Generally, orders to sell Shares may be initiated at any time at janushenderson.com/individual, by telephone, or in writing. Certain accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Funds can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide
57 | Janus Investment Fund

alternate instructions, your proceeds will be invested in Shares of Janus Henderson Government Money Market Fund during the 15-day hold period.
Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. A temporary hold may also be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult has occurred, is occurring, has been attempted, or will be attempted, as described under “Temporary Suspension of Services.”
Note: For the fastest and easiest way to redeem shares, log on to janushenderson.com/individual* 24 hours a day, 7 days a week.

Large Shareholder Redemptions
Certain large shareholders, such as other funds, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s or underlying fund’s shares. Redemptions by these large shareholders of their holdings may cause a Fund or underlying fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large purchases may adversely affect a Fund’s or underlying fund’s performance to the extent that the Fund or underlying fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s or underlying fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If a Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Written Instructions
To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus Henderson.” Requests or documents received in a language other than English may be
58 | Janus Investment Fund

inadvertently delayed or returned due to an inability to accurately translate the intended instructions. Please include the following information:
the name of the Janus Henderson fund(s) being redeemed or exchanged;
the account number(s);
the amount of money or number of shares being redeemed or exchanged;
the name(s) on the account;
the signature(s) of one or more registered account owners; and
your daytime telephone number.
Signature Guarantee
A signature guarantee for each registered account owner is required if any of the following is applicable:
You request a redemption by check above a certain dollar amount.
You would like a check made payable to anyone other than the shareholder(s) of record.
You would like a check mailed to an address that has been changed within 10 days of the redemption request.
You would like a check mailed to an address other than the address of record.
You would like your redemption proceeds sent to a bank account other than a bank account of record.
The Funds reserve the right to require a signature guarantee under other circumstances or to reject or delay a redemption on certain legal grounds.
A signature guarantee may be refused if any of the following is applicable:
It does not appear valid or in good form.
The transaction amount exceeds the surety bond limit of the signature guarantee.
The guarantee stamp has been reported as stolen, missing, or counterfeit.
How to Obtain a Signature Guarantee
A signature guarantee assures that a signature is genuine. The signature guarantee protects shareholders from unauthorized account transfers. The following financial institutions may guarantee signatures: banks, savings and loan associations, trust companies, credit unions, broker-dealers, and member firms of a national securities exchange. Call your financial institution to see if it has the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Funds are intended for long-term investment purposes, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies and procedures may be cancelled or rescinded by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Funds are also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Funds monitor for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds at all times reserve the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund.
59 | Janus Investment Fund

The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.
In an attempt to deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Funds’ excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Funds by a collective investment trust managed by the Adviser; (iv) transactions in the Funds by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.
Excessive Trading Risks
Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Underlying funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by an underlying fund, which, in turn, may be held by a Fund, based on events occurring after the close of a foreign market that may not be reflected in the underlying fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in underlying funds which do not invest in foreign securities, for example, when trading in a security held by an underlying fund is halted and does not resume prior to the time the underlying fund calculates its NAV (referred to as “stale pricing”). Underlying funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the underlying fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of the underlying fund or a Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by an underlying fund despite the underlying funds’ adoption of policies and procedures intended to reduce the underlying fund’s exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Funds to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.

Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of each Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for each Fund at janushenderson.com/reports. A complete schedule of each Fund’s portfolio holdings is also available in the annual and semiannual financial statements located in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. Each Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Funds’ Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.
Shareholder services and account policies
Address Changes
For the easiest way to change the address on your account, visit janushenderson.com/individual. You may also call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Include the name of the Janus Henderson fund(s) you hold, the account number(s), the name(s) on the account, and both the old and new addresses. Certain options may be suspended for 10 days following an address change unless a signature guarantee is provided.
Bank Account Changes
For the easiest way to change your bank account of record or add new bank account information to your account, visit janushenderson.com/individual. You may also send a written request signed by the shareholder of record or by each shareholder of record if more than one. Certain accounts may require a written notice and, in some instances, bank privileges may not be available. If multiple account owners are named on the added bank account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.
You may revoke the authorization to use your bank account information at any time by visiting janushenderson.com/individual, or by sending a written request by mail (Janus Henderson, P.O. Box 219109, Kansas City, MO 64121-9109), or by telephone at 1-800-525-3713. Your request will be processed within a reasonable amount of time upon its receipt.
Distributions
Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janushenderson.com/individual, call a Janus Henderson representative, or send a written request signed by one or more shareholder(s) of record.
Your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.
Involuntary Redemptions
The Funds reserve the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Funds. This includes, but is not limited to, accounts that a Fund or its agents
61 | Janus Investment Fund

believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.
Lost (Unclaimed/Abandoned) Accounts
It is important that the Funds maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Funds as undeliverable. Based upon statutory requirements for returned mail, the Adviser will attempt to locate the shareholder or rightful owner of the account. If the Adviser is unable to locate the shareholder, then the Adviser is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
Online and Telephone Transactions
You may initiate many transactions through janushenderson.com/individual or by calling Janus Henderson XpressLine. You may also contact a Janus Henderson representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please call a Janus Henderson representative. The Funds and their agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.
Your ability to access your account or transact business electronically may be impacted due to unexpected circumstances, such as system outages, or during periods of increased web activity. For example, periods of substantial market change or other unexpected events can contribute to high call volumes, which may delay your ability to reach a Janus Henderson representative by telephone.
If you experience difficulty transacting business with us through a particular method, please consider using an alternate method, such as visiting janushenderson.com/individual, calling Janus Henderson XpressLine, contacting a Janus Henderson representative by telephone, or sending written instructions to complete your transaction. Please remember that purchase, exchange, or redemption requests must be received in good order by a Fund or its agents prior to the close of the trading session of the NYSE in order to receive that day’s NAV.
Your account information, including online credentials, should be kept private, and you should immediately review any account statements that you receive from Janus Henderson. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus Henderson immediately about any transactions you believe to be unauthorized.
Registration Changes
To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janushenderson.com/individual or call a Janus Henderson representative for further instructions.
Statements, Reports, and Prospectuses
We will send you a confirmation upon the completion of individual account transactions. We will also send you quarterly account statements detailing financial transactions on open accounts processed year-to-date. Systematic transactions are confirmed on quarterly statements unless otherwise requested. Confirmations and quarterly account statements will be sent to the account address of record unless you have elected to receive online statements. The Funds reserve the right to charge a fee for additional account statement requests.
At account setup, or any time thereafter, you may elect (at janushenderson.com/edelivery) to discontinue physical delivery of quarterly account statements and/or confirmations, and instead receive an e-mail notification when they are available online. All statements are available online regardless of your delivery option elections (to view, you must first establish online access at janushenderson.com/individual).
The Funds produce shareholder reports semiannually, and update their prospectus annually. You may elect to receive shareholder reports and prospectus updates electronically at janushenderson.com/edelivery. The Funds’ fiscal year ends June 30.
62 | Janus Investment Fund

Unless you instruct Janus Henderson otherwise by contacting a Janus Henderson representative, the Funds will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Funds receive your instructions.
Taxpayer Identification Number
On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Funds to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Funds for any penalty that the IRS may impose.
Temporary Suspension of Services
The Funds or their agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Funds may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Funds to redeem their Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.
In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (i) a natural person age 65 and older, or (ii) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests. We may not be aware of factors suggesting financial exploitation of a Specified Adult and may not be able to identify Specified Adults in all circumstances. Furthermore, we are not required to delay the disbursement of redemption proceeds and do not assume any obligation to do so.

Financial highlights
The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable.

Appendix A – investment objectives and strategies of the janus henderson underlying funds
The following information provides a brief description of the investment objectives and strategies of the Janus Henderson underlying funds that are available. Additional details are available in the underlying funds’ prospectuses. The Trustees of the underlying funds may change the investment objectives or strategies of the underlying funds at any time without prior notice to Fund shareholders.
The Funds may allocate assets to all or some of these underlying funds when rebalancing the Funds’ investments. At the discretion of the Adviser and without shareholder notice, the Funds may invest in additional funds established in the future.
Janus Henderson Absolute Return Income Opportunities Fund seeks to maximize total return, consistent with preservation of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. For purposes of this 80% policy, the term bonds refers to a variety of fixed-income securities and instruments, and includes, but is not limited to, such investments as government notes and bonds, corporate bonds, convertible securities, commercial paper, commercial and residential mortgage-backed securities, asset-backed securities, collateralized loan obligations, fixed rate notes, floating rate securities, and derivatives such as forwards, swap agreements, futures contracts, and options that provide exposure to various fixed-income instruments (“Fixed-Income Instruments”). The fund may invest a significant portion of its assets in certain types of Fixed-Income Instruments, including mortgage-backed securities. In pursuing its investment objective, the fund will have exposure to investments that are economically tied to a number of countries throughout the world. The fund seeks to achieve positive returns that exceed its benchmark index in a variety of market environments. The fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income, while at the same time seeking to provide low volatility. The fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed-income market. For example, portfolio management may favor investments in smaller countries or regions that tend to be underrepresented in fixed-income indices that are more heavily focused on the United States or other larger regions globally.
Janus Henderson Adaptive Risk Managed U.S. Equity Fund seeks long-term growth of capital. The fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies, including, but not limited to, common stocks and depositary receipts. Under normal circumstances, the fund seeks to achieve returns with lower volatility over a full market cycle than the Russell 1000® Index (the fund’s broad-based benchmark index). The fund seeks to generate such returns with volatility that can range from approximately 0% to 40% lower than the Russell 1000 Index. In this context, volatility refers to the variation in the returns of the fund and the broad-based benchmark index as measured by the standard deviation of monthly returns. The market capitalization of issuers within the broad-based benchmark index, from which the fund’s investment universe is derived, will vary, but as of June 30, 2024, they ranged from approximately $170 million to $3.32 trillion.
Janus Henderson Balanced Fund seeks long-term capital growth, consistent with preservation of capital and balanced by current income. The fund pursues its investment objective by normally investing 35-70% of its assets in equity securities and the remaining assets in fixed-income securities and cash equivalents. The fund normally invests at least 25% of its assets in fixed-income senior securities. The fund’s equity investments include, but are not limited to, common stocks and other securities with equity characteristics. The fund’s fixed-income investments include, but are not limited to, government notes and bonds, corporate bonds, commercial and residential mortgage-backed securities, and asset-backed securities. The fund may also invest in money market instruments. The fund may invest in fixed and floating rate obligations with varying durations. The fund will limit its investments in high-yield bonds (also known as “junk” bonds) to 35% of the fixed-income portion of its net assets. The fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The fund also invests in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. The fund may also invest in foreign securities, which may include investments in emerging market securities.
Janus Henderson Contrarian Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities with the potential for long-term growth of capital. The fund normally invests in a portfolio of 35-55 common stocks. Portfolio management seeks to invest in companies where the stock price trades at a significant discount to portfolio management’s estimate of fair value and whose intrinsic value the portfolio management believes will grow over time. The fund may invest in companies of any size, from larger, well-established companies to smaller, emerging growth companies. The fund may also invest in fixed-income instruments, such as convertible securities and preferred stock. The fund may invest in foreign securities.

Janus Henderson Corporate Bond ETF seeks total return consisting of income and capital appreciation, while giving special consideration to certain ESG factors. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. dollar denominated corporate bonds and commercial paper of various maturities. Under normal circumstances, no more than 15% of the fund’s net assets will be invested in securities rated below investment grade; however, such bonds will have a minimum rating of B- by a Nationally Recognized Statistical Ratings Organization or, if unrated, determined to be of comparable credit quality by the Adviser. The fund may invest up to 20% of its net assets in other domestic or foreign debt securities, including U.S. Treasuries, bank loans, and cash and cash alternatives. The fund may concentrate its portfolio investments in any one industry or group of industries under certain circumstances. Generally, the fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the fund’s performance benchmark at the time of investment, the fund may invest up to 35% of its total assets in that industry. The fund may use derivatives, including, but not limited to, swaps (including interest-rate swaps, total rate of returns swaps and credit default swaps), swaptions, options, futures, and options on futures, which may be used for risk, duration and yield-curve management, or to enhance expected returns. Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, interest rates, currencies, or market indices. The fund may enter into reverse-repurchase agreements and use the proceeds to invest in securities consistent with the fund’s principal investment strategies. The fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
Janus Henderson Developed World Bond Fund seeks total return through current income and capital appreciation. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds or other income-producing debt-related securities from developed countries.

Under normal circumstances, portfolio management intends to invest at least 40% of the fund’s net assets outside of the United States and in at least three different countries. The fund may also invest up to 20% of its net assets in equity and equity-related securities such as convertibles and debt securities with warrants. While the fund has no policy limiting the currency in which foreign securities may be denominated, the fund seeks to hedge its non-dollar investments back to the U.S. dollar. Securities in which the fund may invest include: all types of bonds, debentures, mortgage-related and other asset-backed securities, investment grade debt securities (including corporate debt, developed market government bonds and U.S. Government securities), high yield securities (also known as “junk” bonds), foreign securities, subordinated bank debt, collective investment schemes, domestic or foreign floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. Portfolio management may shift the fund’s assets among various types of income-producing securities based upon changing market conditions. The fund’s average portfolio duration normally may range from zero to plus nine years. Portfolio management may lengthen or shorten the fund’s duration based on their outlook on interest rates and inflation. The fund may invest in issuers of any credit quality. The fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.

68 | Janus Investment Fund

securities of issuers that are economically tied to emerging markets countries, including frontier markets countries. Emerging market countries consist of countries included in the International Monetary Fund list of Emerging and Developing Economies.
Janus Henderson Enterprise Fund seeks long-term growth of capital. The fund pursues its investment objective by investing primarily in common stocks selected for their growth potential, and normally invests at least 50% of its equity assets in medium-sized companies. The fund considers medium-sized companies to be those whose market capitalization falls within the range of companies in the Russell Midcap® Growth Index. The market capitalizations within the index will vary, but as of September 30, 2023, they ranged from approximately $223 million to $48.89 billion. The fund may also invest in foreign securities.
Janus Henderson European Focus Fund seeks long-term capital appreciation primarily through investment in equities of European companies.

The fund generally invests in a portfolio of 35-60 equity securities. Equity securities include common stocks and related securities. Portfolio management seeks investments that will increase in value by emphasizing stock selection. Stock selection is based on an opportunistic approach which seeks to utilize stock specific criteria and global market and industry dynamics that are expected to drive stock prices of European companies. Portfolio management will invest in both “growth” stocks that portfolio management believes are reasonably priced and “value” stocks that are, in portfolio management’s opinion, undervalued.
Janus Henderson Flexible Bond Fund seeks to obtain maximum total return, consistent with preservation of capital. The fund pursues its investment objective by primarily investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds.

The fund may invest in fixed and floating rate obligations with varying durations. The fund’s average portfolio duration typically ranges between three and seven years. The fund will invest at least 65% of its net assets in investment grade debt securities. The fund will limit its investment in high-yield bonds to 35% or less of its net assets. The fund generates total return from a combination of current income and capital appreciation, but income is usually the dominant portion. The fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The fund also invests in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. The fund may also invest in foreign securities.
Janus Henderson Forty Fund seeks long-term growth of capital.

The fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of income-producing equity securities, such as common and preferred dividend-paying stocks. The fund invests in U.S. and non-U.S. issuers and will typically invest at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. The fund has no specific policy on the number of different countries in which it will invest but intends to invest in at least three different countries. In selecting investments, portfolio management primarily seeks to identify companies with attractive long-term business prospects that generate cash and produce attractive levels of dividend income, and which are, in the opinion of portfolio management, undervalued or inexpensive relative to other similar investments. Security selection will be based upon an analysis of a broad range of metrics, including price to earnings ratios, balance sheet strength, valuation relative to asset values, return on equity, and a particular focus on cash flow generation and ability to service growing dividend streams in the medium term.
Janus Henderson Global Life Sciences Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies that portfolio management believes have a life science orientation. In the fund’s pursuit of companies with a life science orientation, the fund has a fundamental policy to normally invest at least 25% of its total assets in
69 | Janus Investment Fund

securities of companies that are categorized in the “life sciences” sector, which may include companies in the following industry groups: pharmaceuticals; biotechnology; health care services; agriculture; cosmetics/personal care; and medical devices. Generally speaking, the “life sciences” relate to maintaining or improving quality of life. So, for example, companies with a “life science orientation” include companies engaged in research, development, production, or distribution of products or services related to health and personal care, medicine, or pharmaceuticals. The fund implements its investment policies by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The fund normally invests in issuers from several different countries, which may include the United States. The fund may, under unusual circumstances, invest in a single country. The fund may invest in shares of companies through initial public offerings and private placements.
Janus Henderson Global Real Estate Fund seeks total return through a combination of capital appreciation and current income. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other equity securities, including, but not limited to, REITs and similar REIT-like entities, such as foreign entities that have REIT characteristics and REOCs. The fund may invest in shares of companies through initial public offerings and secondary offerings. As a fundamental policy, the fund will concentrate 25% or more of its net assets in securities of issuers in real estate or real estate-related industries. The fund’s investment in companies engaged in businesses outside the real estate industry which possess significant real estate holdings will be deemed to be in the real estate industry for purposes of the fund’s investment objective and its policy on industry concentration. The fund also invests in non-U.S. real estate and real estate-related companies. The fund expects under normal market conditions to maintain investments in issuers that are economically tied to different countries throughout the world, including the United States.
Janus Henderson Global Research Fund seeks long-term growth of capital. The fund pursues its investment objective by investing primarily in common stocks selected for their growth potential. The fund may invest in companies of any size located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies. The fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. Because the fund’s investments in foreign securities are partially based on the composition of the fund’s benchmark index, the MSCI World Index, the fund’s exposure to foreign markets may fluctuate in connection with variations in the foreign exposure of the fund’s benchmark index.
Janus Henderson Global Select Fund seeks long-term growth of capital. The fund pursues its investment objective by normally investing in a portfolio of 40-65 domestic and foreign common stocks selected for their growth potential and normally investing at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. The fund may invest in companies of any size throughout the world, from larger, well-established companies to smaller, emerging growth companies. The fund may invest in emerging markets but will normally limit such investments to 30% of its net assets, measured at the time of purchase. The fund may invest in securities of REITs. As of September 30, 2023, the fund held stocks of 59 companies. Of these holdings, 40 comprised approximately 88.21% of the fund’s holdings.
Janus Henderson Global Sustainable Equity Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities. The fund will typically invest in companies whose products and services are considered by portfolio management as contributing to positive environmental or social change and sustainable economic development, including those that are strategically aligned with environmental and social megatrends such as climate change, resource constraints, growing populations, and aging populations. The fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. The fund’s investments may be in non-U.S. currency or U.S. dollar-denominated. The fund generally invests in a core group of 50-70 equity securities, which consist primarily of common stocks, but may also include other types of instruments, such as depositary receipts and warrants. The fund may also invest in REITs. The fund will invest primarily in larger, well-established companies but may also invest in mid- and small-sized companies. The fund’s uninvested assets may be held in cash or cash equivalents.
Janus Henderson Global Technology and Innovation Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies that portfolio management believes will benefit significantly from advances or improvements in technology. These companies generally fall into two categories: (i) companies that portfolio management
70 | Janus Investment Fund

believes have or will develop products, processes, or services that will provide significant technological advancements or improvements; and (ii) companies that portfolio management believes rely extensively on technology in connection with their operations or services. Some of the industries and companies likely to be represented in the fund’s portfolio include e-commerce (companies doing business through the Internet); computer (hardware and software); communications (voice, data, and wireless); industrials; Internet (software, services, and infrastructure equipment); and media and entertainment. The fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. The fund may have exposure to emerging markets. From time to time, the fund may invest in shares of companies through initial public offerings.
Janus Henderson Growth and Income Fund seeks long-term capital growth and current income. The fund pursues its investment objective by investing in dividend-paying common stocks with strong growth potential.
Janus Henderson High-Yield Fund seeks to obtain high current income. Capital appreciation is a secondary investment objective when consistent with its primary investment objective. The fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield/high-risk securities rated below investment grade. Securities rated below investment grade may include their unrated equivalents or other high-yielding securities portfolio management believes offer attractive risk/return characteristics. The fund may at times invest all of its assets in such securities. The fund may also invest in money market instruments and foreign debt securities. The fund may also invest in floating rate obligations, such as collateralized loan obligations, floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The fund may also invest in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities.
Janus Henderson Mid Cap Value Fund seeks capital appreciation. The fund pursues its investment objective by investing primarily in the common stocks of mid-sized companies and focuses on companies whose stock prices are believed to be undervalued by the fund’s portfolio management or that have fallen out of favor with the market. The fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies whose market capitalization falls, at the time of purchase, within the capitalization range of the Russell Midcap® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $170 million to $78.43 billion. From time to time, the fund may invest in shares of companies through initial public offerings. The fund may also invest in foreign securities, as well as in REITs and similar REIT-like entities.
Janus Henderson Mortgage-Backed Securities ETF seeks a high level of total return consisting of income and capital appreciation. The fund seeks to achieve its investment objective by investing mainly in mortgage-related instruments. Under normal circumstances, the fund will invest at least 80%, and often times substantially all, of its net assets (plus any borrowings for investment purposes) in a portfolio of mortgage-related fixed income instruments of varying maturities. Mortgage-related fixed income instruments include residential and commercial mortgage-backed securities (“MBS”), collateralized mortgage obligations, stripped mortgage-backed securities, mortgage pass-through securities, credit risk transfer securities, and other securities representing an interest in or secured by or related to mortgages, including asset-backed securities and securities issued by other ETFs that invest principally in MBS. Under normal circumstances, the fund will invest predominantly in mortgage-related securities issued by the U.S. government and its agencies, such as the Government National Mortgage Association, the Federal National Mortgage Association or the Federal Home Loan Mortgage Corporation. The fund may also invest up to 20% of its net assets in non-agency, or privately-issued, residential and commercial MBS, and other non-agency or privately issued mortgage-related and asset-backed securities. The fund will typically enter into “to be announced” or “TBA” commitments when purchasing MBS, which allows the fund to agree to pay for certain yet-to-be issued securities at a future date and which may have a leveraging effect on the fund. Similar to its use of leverage with respect to TBAs, the fund may enter into reverse repurchase agreement transactions and use the cash made available from these transactions to make additional investments in mortgage-related instruments or other fixed-income securities. In addition to its investments in mortgage-backed and mortgage-related securities, the fund will from time to time also invest in certain other fixed-income securities and/or hold cash and cash-equivalents (such as U.S. treasuries). The fund will invest primarily in securities rated investment grade (that is, securities rated Baa3/BBB- or higher, or if unrated, determined to be of comparable credit quality by the Adviser). The fund may also invest in lower-rated, higher-yielding securities, including securities rated below investment grade, when the Adviser believes that the increased risk of such lower rated securities is justified by the potential for increased return. The fund invests only in U.S. dollar denominated securities. The fund may
71 | Janus Investment Fund

invest its uninvested cash in affiliated or non-affiliated money market funds or unregistered cash management pooled investment vehicles that operate as money market funds. The fund also invests in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. Additionally, the fund may invest in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, interest rates, or market indices. In particular, the fund may use swaps, futures, forward contracts and options. The fund may use derivatives only to manage or hedge portfolio risk, including interest rate risk, or to manage duration. The fund’s exposure to derivatives will vary. The fund may also enter into short positions for hedging purposes.
Janus Henderson Overseas Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers or companies from countries outside of the United States. The fund normally invests in a portfolio of 30-50 securities of issuers from several different countries, excluding the United States, and it may under unusual circumstances, invest all or substantially all of its assets in a single country. The fund may invest up to 20% of its net assets, measured at the time of purchase, in U.S. issuers. The fund may have significant exposure to emerging markets. The fund typically invests in equity securities (such as stocks or any other security representing an ownership interest) in all market capitalizations.
Janus Henderson Research Fund seeks long-term growth of capital. The fund pursues its investment objective by investing primarily in common stocks selected for their growth potential. The fund may invest in companies of any size, from larger, well-established companies to smaller, emerging growth companies.
Janus Henderson Responsible International Dividend Fund seeks income with the potential for capital growth over the long-term. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-producing equity securities. The fund may invest in common stocks, preferred stocks, depository receipts, and other equity-related securities. The fund’s investment approach (i) seeks to avoid companies and industries that it considers to be involved in business activities and behaviors that may be environmentally and/or socially harmful, and (ii) considers ESG factors and a company’s management of ESG risks. The fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. The fund’s investments may be in non-U.S. currency or U.S. dollar-denominated.
In selecting investments for the fund, portfolio management first seeks to identify equity securities of companies with attractive long-term business prospects that generate profits and produce attractive levels of dividend income. Although the fund does not have a specific policy regarding the growth/value orientation or market capitalization of the companies in which it invests, portfolio management believes that focusing on dividend-producing equity securities will tend to lead to investments in mid-to-large capitalization “value” stocks (stocks of well-established, undervalued companies that portfolio management believes offer the potential for income and long-term capital appreciation). Portfolio management may, however, invest in smaller and less seasoned issuers and in stocks that are considered “growth” stocks. Next, portfolio management applies broad-based negative screens, which incorporate third party inputs, to seek to avoid companies and industries that are directly associated with business activities and behaviors that may be environmentally and/or socially harmful, subject to certain de minimis limits that may be quantitative (e.g., expressed as a company’s revenues) or qualitative in nature.
Janus Henderson Short Duration Flexible Bond Fund seeks as high a level of current income as is consistent with preservation of capital. The fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in short- and intermediate-term securities such as corporate bonds or notes or government securities, including agency securities, commercial and residential mortgage-backed securities, and asset-backed securities. The fund may invest in fixed and floating rate obligations with varying durations and credit risk transfer securities. The fund will invest at least 65% of its net assets in investment grade debt securities. The fund may invest up to 35% of its net assets in high-yield bonds. The fund’s investments in short-term securities may include money market instruments. The fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities, and may also invest in inflation-linked securities, including Treasury Inflation-Protected Securities, also known as TIPS. The fund may also invest in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. The fund may also invest in foreign securities. The fund’s average portfolio duration typically ranges between one and three years.
Janus Henderson Short Duration Income ETF seeks to provide a steady income stream with capital preservation across various market cycles. The fund seeks to consistently outperform the FTSE 3-Month US Treasury Bill Index by a moderate amount through various market cycles while at the same time providing low volatility. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in a portfolio of fixed income instruments of
72 | Janus Investment Fund

varying maturities. As a general indication of the fund’s risk/return profile, portfolio management will seek to select fixed-income instruments that can provide a return of 2-3% (net of fees) above the FTSE 3-Month US Treasury Bill Index. The fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income while at the same time providing low volatility. The fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed income market. The types of fixed income instruments in which the fund may invest include bonds, debt securities, and other similar instruments issued by various U.S. and foreign public- or private-sector entities. The fund may invest up to 20% of its assets in asset-backed securities that are rated investment grade or of similar quality as determined by the Adviser. From time to time, the fund may invest up to 5% of its assets in asset-backed securities that are rated below investment grade, and up to 5% in non-agency mortgage-backed securities, so long as such instruments, together with other asset-backed securities held by the fund, do not exceed 20% of the fund’s net assets. The fund may also invest in cash or cash equivalents such as commercial paper, repurchase agreements and other short-term fixed-income securities. The fund may invest its uninvested cash in affiliated or non-affiliated money market funds. The fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities. Under normal circumstances, the average portfolio duration of the fund generally will be within 0-2 years of the FTSE 3-Month US Treasury Bill Index. The fund normally invests in investment grade debt securities. The fund may invest in high-yield bonds, commercial paper, mortgage-backed securities, and floating rate securities that are rated below investment grade (commonly known as “high-yield debt” or “junk” bonds), but generally intends to invest 15% or less of its net assets in such securities. The fund may invest up to 70% of its assets in foreign securities. The fund may use futures, options and swaps in connection with its principal strategies in certain market conditions for various investment purposes, such as to manage or hedge portfolio risk, enhance return, or manage duration.
Janus Henderson Small Cap Growth Alpha ETF seeks investment results that correspond generally, before fees and expenses, to the performance of its underlying index, the Janus Henderson Small Cap Growth Alpha Index (the “Underlying Index”). The fund pursues its investment objective by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in the securities that comprise the Underlying Index. The Underlying Index is composed of common stocks of small-sized companies that are included in the Solactive Small Cap Index, a universe of 2,000 small-sized capitalization stocks. The Solactive Small Cap Index uses the total public market value, or “free-float,” capitalization of a stock to determine whether to include such stock in the Solactive Small Cap Index. The Underlying Index is designed to select small-sized capitalization stocks that are poised for “smart growth” by evaluating each company’s performance in three critical areas: growth, profitability, and capital efficiency. Using a proprietary quantitative methodology, such stocks are scored based on fundamental measures of their growth, profitability, and capital efficiency, and the top 10% of such eligible stocks scoring the highest become the constituents of the Underlying Index. Market capitalizations within the Underlying Index will vary, but as of October 31, 2023, they ranged from approximately $24 million to $9.02 billion. The fund uses a “passive,” index-based approach in seeking performance that corresponds to the performance of the Underlying Index. The fund generally will use a replication methodology, meaning it will invest in the securities composing the Underlying Index in proportion to the weightings in the Underlying Index. However, the fund may utilize a sampling methodology under various circumstances in which it may not be possible or practicable to purchase all of the securities in the Underlying Index. The fund may also invest in investments that are not included in the Underlying Index. Such investments include stocks, shares of other investment companies, cash and cash equivalents, including affiliated or non-affiliated money market funds (or unregistered cash management pooled investment vehicles that operate as money market funds).
Janus Henderson Small Cap Value Fund seeks capital appreciation. The fund pursues its investment objective by investing primarily in the common stocks of small companies and focuses on companies whose stock prices are believed to be undervalued by the fund’s portfolio management or that have fallen out of favor with the market. The fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization for companies included in the Russell 2000® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $3 million to $13.14 billion. The 12-month average of the maximum market capitalization for companies included in the Russell 2000 Value Index for the one-year period ended June 30, 2024 was $8.48 billion. From time to time, the fund may invest in shares of companies through initial public offerings. The fund may also invest in foreign securities, as well as REITs and similar REIT-like entities.
Janus Henderson Small-Mid Cap Growth Alpha ETF seeks investment results that correspond generally, before fees and expenses, to the performance of its underlying index, the Janus Henderson Small/Mid Cap Growth Alpha Index (the “Underlying Index”). The fund pursues its investment objective by normally investing at least 80% of its net assets (plus any
73 | Janus Investment Fund

borrowings for investment purposes) in the securities that comprise the Underlying Index. The Underlying Index is designed to select small- and medium-sized capitalization stocks that are poised for “smart growth” by evaluating each company’s performance in three critical areas: growth, profitability, and capital efficiency. A stock may not represent more than 3% of the Underlying Index. The Underlying Index seeks risk adjusted outperformance relative to a market capitalization weighted universe of small- and medium-sized capitalization growth stocks. Market capitalizations within the Underlying Index will vary, but as of October 31, 2023, they ranged from approximately $24 million to $32.22 billion.
Janus Henderson Small-Mid Cap Value Fund seeks capital appreciation. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of small- and mid-sized companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization of companies included in the Russell 2500tm Value Index. The market capitalizations within the index will vary but, as of June 30, 2024, they ranged from approximately $3 million to $30.32 billion. The 12-month average of the maximum market capitalization of companies included in the Russell 2500 Value Index for the one-year period ended June 30, 2024 was $23.19 billion. The fund focuses on companies whose stock prices are believed to be undervalued by the fund’s portfolio management or that have fallen out of favor with the market. The fund normally invests in a portfolio of 35-50 equity securities, which consist primarily of common stocks, but may also include other types of instruments. From time to time, the fund may invest in shares of companies through initial public offerings. The fund may also invest in foreign securities, as well as in REITs and similar REIT-like entities.
Janus Henderson Triton Fund seeks long-term growth of capital. The fund pursues its investment objective by investing at least 50% of its equity assets in small- and medium-sized companies. The fund may also invest in larger companies with strong growth potential. Small- and medium-sized companies are defined by portfolio management as those companies whose market capitalization falls within the range of companies in the Russell 2500tm Growth Index at the time of initial purchase. The market capitalizations within the index will vary, but as of September 30, 2023, they ranged from approximately $3 million to $16.75 billion. The fund may invest in shares of companies through initial public offerings and secondary offerings.
Janus Henderson U.S. Dividend Income Fund seeks to provide current income and aims to provide a growing stream of income per share over time.

The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-paying equity securities of U.S. companies. The fund generally invests in a core group of approximately 40-50 equity securities, including common stocks. The fund will invest primarily in larger, well-established companies. Portfolio management primarily seeks to identify high-quality companies with the ability to grow revenue and cash flows and produce growing dividend streams through disparate economic environments. Such companies, in portfolio management’s view, have the ability to participate in market gains while offering resilient dividends.
Janus Henderson U.S. Real Estate ETF seeks total return through a combination of capital appreciation and current income. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. real estate-related companies.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the underlying funds may invest, as well as some general investment terms. The underlying funds may invest in these instruments to the extent permitted by their investment objectives and policies. The underlying funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. An underlying fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Duration is a measurement of price sensitivity to interest rate changes. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by an underlying fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, an underlying fund’s duration is usually shorter than its average maturity. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter duration. For example, the price of a bond portfolio with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. An underlying fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise.
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
High-yield bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba1 or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”

Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that an underlying fund must pay if these investments are profitable, the underlying fund may make various elections permitted by the tax laws. These elections could require that an underlying fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Private placements are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Rule 144A securities are securities that are not registered for sale to the general public under the Securities Act of 1933, as amended, but that may be resold to certain institutional investors.
Senior securities are securities that rank above an issuing company’s other securities in the event of a bankruptcy or liquidation, which means an underlying fund would be in line to receive repayment of its investment before certain of the company’s other creditors.
“To be announced” or “TBA” commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining an underlying fund’s net asset value. Because an underlying fund is generally not required to pay for the security until the settlement date, if the underlying fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
77 | Janus Investment Fund

Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
Zero coupon bonds are debt obligations that do not pay regular cash interest payments at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. An underlying fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. An underlying fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Inflation index swaps involve the exchange by an underlying fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments or an exchange of floating rate payments based on two different reference indices). By design, one of the reference indices is an inflation index, such as the Consumer Price Index.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. An underlying fund may purchase and write put and call options on securities, securities indices, and foreign currencies. An underlying fund may purchase or write such options individually or in combination.
Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period. A fixed-income total return swap may be written on many different kinds of underlying reference assets, and may include different indices for various kinds of debt securities (e.g., U.S. investment grade bonds, high-yield bonds, or emerging market bonds).

Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which a Fund’s or an underlying fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Diversification is a classification given to a fund under the Investment Company Act of 1940, as amended. Funds are classified as either diversified or nondiversified. To be classified as diversified under the Investment Company Act of 1940, as amended, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as nondiversified under the Investment Company Act of 1940, as amended, on the other hand, has the flexibility to take larger positions in securities than a fund that is classified as diversified. However, because the appreciation or depreciation of a single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.
Industry concentration for purposes under the Investment Company Act of 1940, as amended, is the investment of 25% or more of an underlying fund’s total assets in an industry or group of industries.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain underlying funds, while others do not emphasize investments in companies of any particular size.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by an underlying fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the underlying fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Short sales in which an underlying fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that an underlying fund owns, or the underlying fund has the right to obtain the amount of the security sold short at a specified date in the future. An underlying fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the underlying fund loses the opportunity to participate in the gain. For short sales, the underlying fund will incur a loss if the value of a security increases during this period because it will be paying more for the security than it has received from the purchaser in the short sale. If the price declines during this period, an underlying fund will realize a short-term capital gain. Although an underlying fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. While there is no limit on each Fund’s use of short sales, the Funds do not intend to enter into short positions. This does not preclude the underlying funds from investing in short sales.
When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which the Fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses the Fund incurs as a result of investing in shares of an underlying fund. The Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any expenses of an underlying fund (acquired fund fees and expenses), the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.14% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including the operating expenses of the underlying funds) are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year

period reflects the conversion to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 111% of the average value of its portfolio.
Principal investment strategies
The Fund seeks to achieve its investment objective by investing in other mutual funds and exchange-traded funds (“ETFs”) (collectively, “underlying funds”) that represent a variety of asset classes and investment styles and provide exposure to issuers that are economically tied to countries throughout the world. Under normal market conditions, the Fund will primarily invest its assets in Janus Henderson underlying funds. The Fund may also invest up to 35% of its assets in underlying funds that are not sponsored by the Adviser, which portfolio management expects will predominantly pursue passively-managed investment strategies.
The Fund invests in a diversified portfolio of underlying funds and will normally allocate 50%-65% of its investments to underlying funds that provide varying exposure to fixed-income and money market instruments, 30%-50% of its investments to underlying funds that provide varying exposure to common stocks of U.S.-based companies and international companies, and 0%-20% of its investments to underlying funds that provide exposure to alternative investments and alternative investment strategies. The underlying fixed-income funds encompass a wide range of fixed-income sectors, including corporate bonds, government securities, mortgage- and asset-backed securities, bank loans, securities that are rated below investment grade, and commercial paper, with varying maturities and duration, credit exposure, and regional exposure. The underlying equity funds may invest across a wide range of market capitalizations and segments, including emerging markets, and employ various investment strategies and styles such as growth and value. The underlying alternative funds may invest in various alternative strategies, including, but not limited to, commodities, currencies, and hedge fund strategies. Because it invests in other funds, the Fund is considered a “fund of funds.”
Through its investments in underlying funds, the Fund invests in issuers from several different countries. As a result, the Fund normally will have approximately 40% to 65% of its net assets allocated to non-U.S. investments. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the company’s revenues are derived from outside of the United States; or (iii) a majority of the company’s assets are located outside of the United States. The Fund may also have significant exposure to emerging markets.
In managing the Fund, portfolio management employs a proprietary methodology that combines strategic asset allocation and dynamic asset allocation. The strategic asset allocation process is based on an assessment of long-term return, risk, and correlation expectations of various asset classes and is normally applied on an annual basis. The dynamic asset allocation
3 | Janus Henderson Global Allocation Fund – Conservative

process gives portfolio management the ability to express shorter-term market views and to react to market changes by adjusting the Fund’s exposure to the underlying funds and is normally applied on a quarterly basis.
When market conditions dictate a more defensive strategy, the Fund or an underlying fund may temporarily hold cash or invest its assets in temporary investments. In that case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Refer to Appendix A of the Prospectus for a brief description of the investment strategies of each of the currently available Janus Henderson underlying funds. The underlying funds, and the Fund’s investment in any underlying fund, may change at any time without prior notice.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking income and, to a lesser extent, growth of capital. The principal risks associated with investing in the Fund and the underlying funds are set forth below.
Fund-Level Risks
Affiliated Underlying Fund Risk.The Adviser has the authority to select and substitute the underlying funds. The Adviser is subject to conflicts of interest in allocating the Fund’s assets among certain Janus Henderson underlying funds both because the fees payable to it by the Janus Henderson underlying funds differ and because the Adviser is also responsible for managing the Janus Henderson underlying funds. In addition, the Adviser’s authority to allocate investments among the Janus Henderson underlying funds and underlying funds that are not sponsored by the Adviser creates conflicts of interest. For example, investing in Janus Henderson underlying funds could cause the Fund to incur higher fees and may cause the Adviser to receive greater compensation, increase assets under management, or support particular investment strategies. The Adviser, however, is a fiduciary to the Fund and is legally obligated to act in its best interest when selecting underlying funds.
Underlying ETF Risk.Underlying funds that are ETFs (“underlying ETFs”) are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an underlying ETF trades at a premium or discount to its net asset value. Underlying ETFs also involve the risk that an active trading market for an underlying ETF’s shares may not develop or be maintained. Similarly, because the value of underlying ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an underlying ETF at the most optimal time, which could adversely affect the Fund’s performance. Trading of an underlying ETF’s shares may be halted by the activation of individual or market-wide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an underlying ETF’s shares may also be halted if (i) the shares are delisted from an exchange without first being listed on another exchange or (ii) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Allocation Risk.The Fund’s ability to achieve its investment objective depends largely upon portfolio management’s allocation of assets among the underlying funds and other securities using Janus Henderson’s proprietary strategic asset allocation and dynamic asset allocation methodologies. You could lose money on your investment in the Fund as a result of these allocations. The Fund will typically invest in a number of different underlying funds; however, to the extent that the Fund invests a significant portion of its assets in a single underlying fund, it will be more sensitive to the risks associated with that fund and any investments in which that fund focuses.
Investment Process Risk.No assurance can be given that the Fund’s investment strategy will be successful under all or any market conditions. Although the proprietary strategic asset allocation and dynamic asset allocation methodologies are designed to achieve the Fund’s investment objective, there is no guarantee that they will achieve the desired results, and there is a risk that they may not be successful in identifying how the Fund’s allocations and security exposures should be adjusted in order to reduce the risk of loss while participating in the upside growth of capital markets.
Risks Through Investing in the Underlying Funds
The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the underlying funds realize their respective investment objectives. Similarly, the Fund’s investment performance is directly related to the investment performance of the underlying funds it holds. The Fund is subject to the risk factors associated with the investments of the underlying funds, and will be affected by such risks in direct proportion to the allocation of its assets
4 | Janus Henderson Global Allocation Fund – Conservative

among the underlying funds. Therefore, to the extent that the Fund invests significantly in a particular underlying fund, the Fund’s performance would be significantly impacted by the performance of such underlying fund. What follows are the main risks associated with the underlying funds, which, in turn, may be considered to be principal risks of the Fund. These risks are subject to change based on the allocation of the Fund’s assets among the underlying funds.
Market Risk.The value of an underlying fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, an underlying fund’s net asset value may fluctuate and it may be more difficult to value or sell an underlying fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Equity Securities Risk.Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of an underlying fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries in which the issuers of securities the underlying fund holds participate.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in an underlying fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price the underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If an underlying fund’s portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing an underlying fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing
5 | Janus Henderson Global Allocation Fund – Conservative

countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of an underlying fund’s investments. To the extent that an underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.
Small- and Mid-Sized Companies Risk.Certain of the underlying fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holding are also subject to wider price fluctuations and tend to be less liquid that stock of larger or more established companies, which could have a significant adverse effect on an underlying fund’s returns, especially as market conditions change.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which an underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, an underlying fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where an underlying fund has invested a significant amount of its assets may have a greater effect on an underlying fund’s performance than it would in a more geographically diversified portfolio.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
6 | Janus Henderson Global Allocation Fund – Conservative

Portfolio Management Risk.Certain of the underlying funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and/or research process employed for those underlying funds may fail to produce the intended results. Accordingly, such underlying funds may underperform their respective benchmark indexes or other mutual funds with similar investment objectives.
Passive Investment Risk.Certain of the underlying funds are not actively managed and therefore an underlying fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the underlying fund’s specific benchmark index or the selling of shares is otherwise required upon a rebalancing of the specific benchmark index. Maintaining investments in securities without attempting to take defensive positions, regardless of market conditions or the performance of individual securities, could cause an underlying fund’s return to be lower than if it had employed an active strategy.
Volatility Risk.There is no guarantee that Janus Henderson Adaptive Risk Managed U.S. Equity Fund’s, an underlying fund, strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage.
Counterparty Risk.Certain derivative and “over-the-counter” instruments, such as swaps and forwards, are subject to the risk that the other party to a contract will not fulfill its contractual obligations.
Alternative Investments Allocation Risk.There is a risk that the returns provided by alternative investments may be subject to high volatility and that an underlying fund’s portfolio management’s beliefs about the expected returns, risk and correlation properties of one or more of an underlying fund’s investments may be incorrect. There is also a risk that an underlying fund’s investments will correlate with the performance of stocks and bonds to a greater degree than anticipated. All of these factors may negatively affect your investment in the Fund and you could lose money. Investment in the underlying funds also involves derivatives, counterparty, leverage, real estate-related, and commodity-linked investment risks.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund commenced operations on July 6, 2009.
The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, and Class I Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. Performance information for each underlying fund is available in its prospectus and/or the most recent annual or semiannual report. The bar chart figures

do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 20, 2024, the Fund changed its investment strategy. Performance prior to June 20, 2024 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.

The Fund’s broad-based benchmark index is the Bloomberg Global Aggregate Bond Index. The Fund’s additional benchmark is the Global Conservative Allocation Index. The indices are described below.
The Bloomberg Global Aggregate Bond Index is a broad-based measure of the global investment grade fixed-rate debt markets.
The Global Conservative Allocation Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the Bloomberg Global Aggregate Bond Index (60%) and the MSCI All Country World Indexsm (40%).
After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which the Fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses the Fund incurs as a result of investing in shares of an underlying fund. The Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any expenses of an underlying fund (acquired fund fees and expenses), the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.12% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including the operating expenses of the underlying funds) are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 104% of the average value of its portfolio.
Principal investment strategies
The Fund seeks to achieve its investment objective by investing in other mutual funds and exchange-traded funds (“ETFs”) (collectively, “underlying funds”) that represent a variety of asset classes and investment styles and provide exposure to issuers that are economically tied to countries throughout the world. Under normal market conditions, the Fund will primarily invest its assets in Janus Henderson underlying funds. The Fund may also invest up to 35% of its assets in underlying funds that are not sponsored by the Adviser, which portfolio management expects will predominantly pursue passively-managed investment strategies.
The Fund invests in a diversified portfolio of underlying funds and will normally allocate 45%-65% of its investments to underlying funds that provide varying exposure to common stocks of U.S.-based companies and international companies, 30%-45% of its investments to underlying funds that provide varying exposure to fixed-income and money market instruments, and 0%-20% of its investments to underlying funds that provide exposure to alternative investments and alternative investment strategies. The underlying equity funds may invest across a wide range of market capitalizations and segments, including emerging markets, and employ various investment strategies and styles such as growth and value. The underlying fixed-income funds encompass a wide range of fixed-income sectors, including corporate bonds, government securities, mortgage- and asset-backed securities, bank loans, securities that are rated below investment grade, and commercial paper, with varying maturities and duration, credit exposure, and regional exposure. The underlying alternative funds may invest in various alternative strategies, including, but not limited to, commodities, currencies, and hedge fund strategies. Because it invests in other funds, the Fund is considered a “fund of funds.”
Through its investments in underlying funds, the Fund invests in issuers from several different countries. As a result, the Fund normally will have approximately 40% to 65% of its net assets allocated to non-U.S. investments. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the company’s revenues are derived from outside of the United States; or (iii) a majority of the company’s assets are located outside of the United States. The Fund may also have significant exposure to emerging markets.
In managing the Fund, portfolio management employs a proprietary methodology that combines strategic asset allocation and dynamic asset allocation. The strategic asset allocation process is based on an assessment of long-term return, risk, and correlation expectations of various asset classes and is normally applied on an annual basis. The dynamic asset allocation
12 | Janus Henderson Global Allocation Fund – Moderate

process gives portfolio management the ability to express shorter-term market views and to react to market changes by adjusting the Fund’s exposure to the underlying funds and is normally applied on a quarterly basis.
When market conditions dictate a more defensive strategy, the Fund or an underlying fund may temporarily hold cash or invest its assets in temporary investments. In that case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Refer to Appendix A of the Prospectus for a brief description of the investment strategies of each of the currently available Janus Henderson underlying funds. The underlying funds, and the Fund’s investment in any underlying fund, may change at any time without prior notice.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking growth of capital and income. The principal risks associated with investing in the Fund and the underlying funds are set forth below.
Fund-Level Risks
Affiliated Underlying Fund Risk.The Adviser has the authority to select and substitute the underlying funds. The Adviser is subject to conflicts of interest in allocating the Fund’s assets among certain Janus Henderson underlying funds both because the fees payable to it by the Janus Henderson underlying funds differ and because the Adviser is also responsible for managing the Janus Henderson underlying funds. In addition, the Adviser’s authority to allocate investments among the Janus Henderson underlying funds and underlying funds that are not sponsored by the Adviser creates conflicts of interest. For example, investing in Janus Henderson underlying funds could cause the Fund to incur higher fees and may cause the Adviser to receive greater compensation, increase assets under management, or support particular investment strategies. The Adviser, however, is a fiduciary to the Fund and is legally obligated to act in its best interest when selecting underlying funds.
Underlying ETF Risk.Underlying funds that are ETFs (“underlying ETFs”) are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an underlying ETF trades at a premium or discount to its net asset value. Underlying ETFs also involve the risk that an active trading market for an underlying ETF’s shares may not develop or be maintained. Similarly, because the value of underlying ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an underlying ETF at the most optimal time, which could adversely affect the Fund’s performance. Trading of an underlying ETF’s shares may be halted by the activation of individual or market-wide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an underlying ETF’s shares may also be halted if (i) the shares are delisted from an exchange without first being listed on another exchange or (ii) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Allocation Risk.The Fund’s ability to achieve its investment objective depends largely upon portfolio management’s allocation of assets among the underlying funds and other securities using Janus Henderson’s proprietary strategic asset allocation and dynamic asset allocation methodologies. You could lose money on your investment in the Fund as a result of these allocations. The Fund will typically invest in a number of different underlying funds; however, to the extent that the Fund invests a significant portion of its assets in a single underlying fund, it will be more sensitive to the risks associated with that fund and any investments in which that fund focuses.
Investment Process Risk.No assurance can be given that the Fund’s investment strategy will be successful under all or any market conditions. Although the proprietary strategic asset allocation and dynamic asset allocation methodologies are designed to achieve the Fund’s investment objective, there is no guarantee that they will achieve the desired results, and there is a risk that they may not be successful in identifying how the Fund’s allocations and security exposures should be adjusted in order to reduce the risk of loss while participating in the upside growth of capital markets.
Risks Through Investing in the Underlying Funds
The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the underlying funds realize their respective investment objectives. Similarly, the Fund’s investment performance is directly related to the investment performance of the underlying funds it holds. The Fund is subject to the risk factors associated with the investments of the underlying funds, and will be affected by such risks in direct proportion to the allocation of its assets
13 | Janus Henderson Global Allocation Fund – Moderate

among the underlying funds. Therefore, to the extent that the Fund invests significantly in a particular underlying fund, the Fund’s performance would be significantly impacted by the performance of such underlying fund. What follows are the main risks associated with the underlying funds, which, in turn, may be considered to be principal risks of the Fund. These risks are subject to change based on the allocation of the Fund’s assets among the underlying funds.
Market Risk.The value of an underlying fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, an underlying fund’s net asset value may fluctuate and it may be more difficult to value or sell an underlying fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Equity Securities Risk.Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of an underlying fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries in which the issuers of securities the underlying fund holds participate.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in an underlying fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price the underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If an underlying fund’s portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing an underlying fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing
14 | Janus Henderson Global Allocation Fund – Moderate

countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of an underlying fund’s investments. To the extent that an underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.
Small- and Mid-Sized Companies Risk.Certain of the underlying fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holding are also subject to wider price fluctuations and tend to be less liquid that stock of larger or more established companies, which could have a significant adverse effect on an underlying fund’s returns, especially as market conditions change.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which an underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, an underlying fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where an underlying fund has invested a significant amount of its assets may have a greater effect on an underlying fund’s performance than it would in a more geographically diversified portfolio.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
15 | Janus Henderson Global Allocation Fund – Moderate

Portfolio Management Risk.Certain of the underlying funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and/or research process employed for those underlying funds may fail to produce the intended results. Accordingly, such underlying funds may underperform their respective benchmark indexes or other mutual funds with similar investment objectives.
Passive Investment Risk.Certain of the underlying funds are not actively managed and therefore an underlying fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the underlying fund’s specific benchmark index or the selling of shares is otherwise required upon a rebalancing of the specific benchmark index. Maintaining investments in securities without attempting to take defensive positions, regardless of market conditions or the performance of individual securities, could cause an underlying fund’s return to be lower than if it had employed an active strategy.
Volatility Risk.There is no guarantee that Janus Henderson Adaptive Risk Managed U.S. Equity Fund’s, an underlying fund, strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage.
Counterparty Risk.Certain derivative and “over-the-counter” instruments, such as swaps and forwards, are subject to the risk that the other party to a contract will not fulfill its contractual obligations.
Alternative Investments Allocation Risk.There is a risk that the returns provided by alternative investments may be subject to high volatility and that an underlying fund’s portfolio management’s beliefs about the expected returns, risk and correlation properties of one or more of an underlying fund’s investments may be incorrect. There is also a risk that an underlying fund’s investments will correlate with the performance of stocks and bonds to a greater degree than anticipated. All of these factors may negatively affect your investment in the Fund and you could lose money. Investment in the underlying funds also involves derivatives, counterparty, leverage, real estate-related, and commodity-linked investment risks.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund commenced operations on July 6, 2009.
The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class A Shares, Class C Shares, and Class S Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for the
16 | Janus Henderson Global Allocation Fund – Moderate

periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, and Class I Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. Performance information for each underlying fund is available in its prospectus and/or the most recent annual or semiannual report. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 20, 2024, the Fund changed its investment strategy. Performance prior to June 20, 2024 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

The MSCI All Country World Index is designed to measure equity market performance in global developed and emerging markets.
The Global Moderate Allocation Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the MSCI All Country World Index (60%) and the Bloomberg Global Aggregate Bond Index (40%).
After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which the Fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses the Fund incurs as a result of investing in shares of an underlying fund. The Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including the operating expenses of the underlying funds) remain the same. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year period reflects the conversion to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 100% of the average value of its portfolio.
Principal investment strategies
The Fund seeks to achieve its investment objective by investing in other mutual funds and exchange-traded funds (“ETFs”) (collectively, “underlying funds”) that represent a variety of asset classes and investment styles and provide exposure to issuers that are economically tied to countries throughout the world. Under normal market conditions, the Fund will primarily invest its assets in Janus Henderson underlying funds. The Fund may also invest up to 35% of its assets in underlying funds that are not sponsored by the Adviser, which portfolio management expects will predominantly pursue passively-managed investment strategies.
The Fund invests in a diversified portfolio of underlying funds and will normally allocate 70%-85% of its investments to underlying funds that provide varying exposure to common stocks of U.S.-based companies and international companies, 10%-25% of its investments to underlying funds that provide varying exposure to fixed-income and money market instruments, and 0%-20% of its investments to underlying funds that provide exposure to alternative investments and alternative investment strategies. The underlying equity funds may invest across a wide range of market capitalizations and segments, including emerging markets, and employ various investment strategies and styles such as growth and value. The underlying fixed-income funds encompass a wide range of fixed-income sectors, including corporate bonds, government securities, mortgage- and asset-backed securities, bank loans, securities that are rated below investment grade, and commercial paper, with varying maturities and duration, credit exposure, and regional exposure. The underlying alternative funds may invest in various alternative strategies, including, but not limited to, commodities, currencies, and hedge fund strategies. Because it invests in other funds, the Fund is considered a “fund of funds.”
Through its investments in underlying funds, the Fund invests in issuers from several different countries. As a result, the Fund normally will have approximately 40% to 65% of its net assets allocated to non-U.S. investments. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, a country outside of the United States; (ii) a majority of the company’s revenues are derived from outside of the United States; or (iii) a majority of the company’s assets are located outside of the United States. The Fund may also have significant exposure to emerging markets.
In managing the Fund, portfolio management employs a proprietary methodology that combines strategic asset allocation and dynamic asset allocation. The strategic asset allocation process is based on an assessment of long-term return, risk, and correlation expectations of various asset classes and is normally applied on an annual basis. The dynamic asset allocation process gives portfolio management the ability to express shorter-term market views and react to market changes by adjusting the Fund’s exposures to the underlying funds and is normally applied on a quarterly basis.
When market conditions dictate a more defensive strategy, the Fund or an underlying fund may temporarily hold cash or invest its assets in temporary investments. In that case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Refer to Appendix A of the Prospectus for a brief description of the investment strategies of each of the currently available Janus Henderson underlying funds. The underlying funds, and the Fund’s investment in any underlying fund, may change at any time without prior notice.

Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking growth of capital and, to a lesser extent, income. The principal risks associated with investing in the Fund and the underlying funds are set forth below.
Fund-Level Risks
Affiliated Underlying Fund Risk.The Adviser has the authority to select and substitute the underlying funds. The Adviser is subject to conflicts of interest in allocating the Fund’s assets among certain Janus Henderson underlying funds both because the fees payable to it by the Janus Henderson underlying funds differ and because the Adviser is also responsible for managing the Janus Henderson underlying funds. In addition, the Adviser’s authority to allocate investments among the Janus Henderson underlying funds and underlying funds that are not sponsored by the Adviser creates conflicts of interest. For example, investing in Janus Henderson underlying funds could cause the Fund to incur higher fees and may cause the Adviser to receive greater compensation, increase assets under management, or support particular investment strategies. The Adviser, however, is a fiduciary to the Fund and is legally obligated to act in its best interest when selecting underlying funds.
Underlying ETF Risk.Underlying funds that are ETFs (“underlying ETFs”) are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an underlying ETF trades at a premium or discount to its net asset value. Underlying ETFs also involve the risk that an active trading market for an underlying ETF’s shares may not develop or be maintained. Similarly, because the value of underlying ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an underlying ETF at the most optimal time, which could adversely affect the Fund’s performance. Trading of an underlying ETF’s shares may be halted by the activation of individual or market-wide “circuit breakers” (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of an underlying ETF’s shares may also be halted if (i) the shares are delisted from an exchange without first being listed on another exchange or (ii) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
Allocation Risk.The Fund’s ability to achieve its investment objective depends largely upon portfolio management’s allocation of assets among the underlying funds and other securities using Janus Henderson’s proprietary strategic asset allocation and dynamic asset allocation methodologies. You could lose money on your investment in the Fund as a result of these allocations. The Fund will typically invest in a number of different underlying funds; however, to the extent that the Fund invests a significant portion of its assets in a single underlying fund, it will be more sensitive to the risks associated with that fund and any investments in which that fund focuses.
Investment Process Risk.No assurance can be given that the Fund’s investment strategy will be successful under all or any market conditions. Although the proprietary strategic asset allocation and dynamic asset allocation methodologies are designed to achieve the Fund’s investment objective, there is no guarantee that they will achieve the desired results, and there is a risk that they may not be successful in identifying how the Fund’s allocations and security exposures should be adjusted in order to reduce the risk of loss while participating in the upside growth of capital markets.
Risks Through Investing in the Underlying Funds
The ability of the Fund to realize its investment objective will depend, in large part, on the extent to which the underlying funds realize their respective investment objectives. Similarly, the Fund’s investment performance is directly related to the investment performance of the underlying funds it holds. The Fund is subject to the risk factors associated with the investments of the underlying funds, and will be affected by such risks in direct proportion to the allocation of its assets among the underlying funds. Therefore, to the extent that the Fund invests significantly in a particular underlying fund, the Fund’s performance would be significantly impacted by the performance of such underlying fund. What follows are the main risks associated with the underlying funds, which, in turn, may be considered to be principal risks of the Fund. These risks are subject to change based on the allocation of the Fund’s assets among the underlying funds.
Market Risk.The value of an underlying fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, an underlying fund’s net asset value may fluctuate and it may be more difficult to value or sell an underlying fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural
22 | Janus Henderson Global Allocation Fund – Growth

disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Equity Securities Risk.Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of an underlying fund’s portfolio may decrease if the value of an individual company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries in which the issuers of securities the underlying fund holds participate.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in an underlying fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price the underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If an underlying fund’s portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing an underlying fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of an underlying fund’s investments. To the extent that an underlying fund invests a significant portion of
23 | Janus Henderson Global Allocation Fund – Growth

its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance.
Small- and Mid-Sized Companies Risk.Certain of the underlying fund’s investments in securities issued by small- and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holding are also subject to wider price fluctuations and tend to be less liquid that stock of larger or more established companies, which could have a significant adverse effect on an underlying fund’s returns, especially as market conditions change.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which an underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, an underlying fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where an underlying fund has invested a significant amount of its assets may have a greater effect on an underlying fund’s performance than it would in a more geographically diversified portfolio.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Portfolio Management Risk.Certain of the underlying funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and/or research process employed for those underlying funds may fail to produce the intended results. Accordingly, such underlying funds may underperform their respective benchmark indexes or other mutual funds with similar investment objectives.
Passive Investment Risk.Certain of the underlying funds are not actively managed and therefore an underlying fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the underlying fund’s specific benchmark index or the selling of shares is otherwise required upon a rebalancing of the specific benchmark index. Maintaining investments in securities without attempting to take defensive positions, regardless of market conditions or the performance of individual securities, could cause an underlying fund’s return to be lower than if it had employed an active strategy.
24 | Janus Henderson Global Allocation Fund – Growth

Volatility Risk.There is no guarantee that Janus Henderson Adaptive Risk Managed U.S. Equity Fund’s, an underlying fund, strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage.
Counterparty Risk.Certain derivative and “over-the-counter” instruments, such as swaps and forwards, are subject to the risk that the other party to a contract will not fulfill its contractual obligations.
Alternative Investments Allocation Risk.There is a risk that the returns provided by alternative investments may be subject to high volatility and that an underlying fund’s portfolio management’s beliefs about the expected returns, risk and correlation properties of one or more of an underlying fund’s investments may be incorrect. There is also a risk that an underlying fund’s investments will correlate with the performance of stocks and bonds to a greater degree than anticipated. All of these factors may negatively affect your investment in the Fund and you could lose money. Investment in the underlying funds also involves derivatives, counterparty, leverage, real estate-related, and commodity-linked investment risks.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund commenced operations on July 6, 2009.
The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class A Shares, Class C Shares, and Class S Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund had been available during periods prior to July 6, 2009, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, and Class I Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. Performance information for each underlying fund is available in its prospectus and/or the most recent annual or semiannual report. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective June 20, 2024, the Fund changed its investment strategy. Performance prior to June 20, 2024 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.

The Fund’s broad-based benchmark index is the MSCI All Country World Index. The Fund’s additional benchmark is the Global Growth Allocation Index. The indices are described below.
The MSCI All Country World Index is designed to measure equity market performance in global developed and emerging markets.
The Global Growth Allocation Index is an internally-calculated, hypothetical combination of unmanaged indices that combines total returns from the MSCI All Country World Index (80%) and the Bloomberg Global Aggregate Bond Index (20%).
After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

Purchases, exchanges, and redemptions can generally be made only through institutional channels, such as financial intermediaries and retirement platforms. You should contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund. Requests must be received in good order by the Fund or its agents (financial intermediary or plan sponsor, if applicable) prior to the close of the trading session of the New York Stock Exchange in order to receive that day’s net asset value. For additional information, refer to “Purchases,” “Exchanges,” and/or “Redemptions” in the Prospectus.
Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional information about the Funds
Fees and expenses
Each Fund, as a shareholder in the underlying funds, will also indirectly bear its pro rata share of the expenses incurred by the underlying funds. The Funds’ returns are net of these expenses. Expenses may be higher or lower depending upon the allocation of the Funds’ assets among the underlying funds and the actual expenses of the underlying funds, including any expenses associated with the underlying funds’ investments in exchange-traded funds.
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Shareholder Fees” are fees paid directly from your investment and may include sales loads.
“Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by each Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Distribution/Service (12b-1) Fees.” Because 12b-1 fees are charged as an ongoing fee, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. Distribution/Service (12b-1) Fees include a shareholder servicing fee of up to 0.25% for Class C Shares.
A contingent deferred sales charge of up to 1.00% may be imposed on certain redemptions of Class A Shares bought without an initial sales charge and then redeemed within 12 months of purchase. The contingent deferred sales charge is not reflected in the Example in each Fund Summary.
A contingent deferred sales charge of 1.00% generally applies on Class C Shares redeemed within 12 months of purchase. The contingent deferred sales charge may be waived for certain investors, as described in the Shareholder’s Guide.
“Other Expenses”
°
for Class A Shares, Class C Shares, and Class I Shares, may include administrative fees charged by intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds.
°
for Class S Shares and Class T Shares, include an administrative services fee of 0.25% of the average daily net assets of each class to compensate Janus Henderson Services US LLC (the “Transfer Agent”), the Funds’ transfer agent, for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of retirement plan participants, pension plan participants, or other underlying investors investing through institutional channels.
°
for all classes, may include reimbursement to the Adviser for certain out-of-pocket costs related to the administration of the Funds and to the Transfer Agent of its out-of-pocket costs for serving as transfer agent and providing, or arranging by others the provision of, servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse each Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus.
All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

Additional investment strategies and general portfolio policies
This Prospectus provides information about the Funds, which seek to achieve their investment objectives by investing in underlying funds that provide exposure to equities, fixed-income securities, money market instruments, and alternative investment strategies. Because they invest in other funds, each Fund is considered a “fund of funds.” A fund of funds bears its own direct expenses in addition to bearing a proportionate share of the expenses charged by the underlying funds in which it invests. The Funds are best suited for long-term investors.
This section takes a closer look at the Funds’ principal investment strategies, as well as certain risks of investing in the Funds. Please carefully review the “Risks of the Funds” section of this Prospectus for a discussion of risks associated with certain investment techniques. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout this Prospectus.
Because investors’ risk tolerances, investment goals, investment time horizons, and financial circumstances may be different, each Fund offers a different strategy for pursuing capital growth and income. The allocation to equities, fixed-income securities, money market instruments, and alternative investment strategies in each Fund reflects its greater or lesser emphasis on pursuing growth of capital or current income. The following illustrates each Fund’s relative emphasis on seeking growth of capital and seeking income.
The following table indicates each Fund’s normal asset allocation range, which is how each Fund’s investments generally will be allocated among the equity, fixed-income, money market, and alternatives asset classes under normal market conditions.

Each Fund will normally allocate its investments to underlying funds that provide varying exposure to U.S.-based companies of varying market capitalizations, international companies (including those with exposure to emerging markets), bonds and money market instruments, derivatives, currency strategies, and alternative investments. The normal asset allocation ranges, as well as the underlying funds and investments in each underlying fund, may change from time to time without shareholder approval or notice.
Although each Fund can invest in any or all of the Janus Henderson underlying funds described in Appendix A of this Prospectus, as well as in underlying funds not sponsored by the Adviser, it is expected that each Fund will normally invest in only some of the underlying funds at any particular time. Each Fund’s investment in underlying funds that are not sponsored by the Adviser will not exceed 35%. A Fund’s investment in any Janus Henderson underlying fund may exceed 25% of such Fund’s total assets. For information on the Janus Henderson underlying funds currently available for investment by the Funds, including their investment objectives and strategies, see “Investment Objectives and Strategies of the Janus Henderson Underlying Funds” in Appendix A. At the discretion of the Adviser and without prior shareholder notification, the Funds may invest in additional underlying funds established in the future.
Actual holdings percentages may vary due to actual cash flows and changes to the underlying funds’ asset values. In addition, the Funds may reallocate their assets among the underlying funds, including investing a portion or all of its assets in cash equivalents or a money market fund. The Funds and certain underlying funds may purchase unlimited shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles. The Adviser may change the asset class allocations, the underlying funds, an underlying fund’s asset category, or weightings among asset classes or underlying funds without prior notice to shareholders. Information regarding a Fund’s actual allocations to underlying funds is available to
30 | Janus Investment Fund

shareholders on a periodic basis through the Funds’ annual reports, semiannual reports, and certain other reports filed with the Securities and Exchange Commission (the “SEC”), as well as at janushenderson.com/advisor/mutual-funds. Please refer to “Availability of Portfolio Holdings Information” in this Prospectus to learn how to access the most recent allocation information.
The proprietary methodology employed by portfolio management normally combines the strategic asset allocation process, on an annual basis, and the dynamic asset allocation process, on a quarterly basis.
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
Unless otherwise stated, the following additional investment strategies and general policies apply to the Funds and the underlying funds. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent.
Cash Position
A Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
Portfolio Turnover
The Funds normally seek long-term investment, although the Funds may sell shares of the underlying funds regardless of how long they have been held. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to shareholder purchases and redemptions), the nature of a Fund’s investments, and the investment style of portfolio management. Changes are normally made in a Fund’s holdings whenever portfolio management believes such changes are desirable. Portfolio turnover rates are generally not a factor in making decisions regarding asset allocations among the underlying funds. The Funds’ transactions in Janus Henderson underlying mutual funds do not entail brokerage commissions, but may result in taxable capital gains. The Funds’ transactions in the underlying ETFs may incur brokerage commissions. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
Risks of the Funds
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The allocation of each Fund’s assets to underlying funds may not be successful in achieving the Fund’s investment objective. There is a risk that you may experience lower returns by investing in a Fund instead of investing directly in an underlying fund. A Fund’s returns are directly related to the aggregate performance and expenses of the underlying funds in which it invests. Certain of the underlying funds in which a Fund may invest have operated for shorter time periods and therefore have limited investment results, smaller asset bases, and estimated expense ratios. Investments by a Fund in such an underlying fund may increase the indirect expenses paid by the Fund and may result in the Fund not achieving its investment objective.
There is additional risk for the Funds with respect to aggregation of holdings of underlying funds. The aggregation of holdings of underlying funds may result in a Fund indirectly having concentrated assets in a particular industry, geographical sector, or single company. Such indirect concentrated holdings may have the effect of increasing the volatility of the Fund’s returns. The Funds do not control the investments of the underlying funds, or any indirect concentration that occurs as a result of the underlying funds following their investment objectives.
The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies employed for the Funds may fail to produce the intended results. A Fund may underperform its benchmark index or other mutual funds with similar investment objectives.

The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, because the Adviser manages the Funds and the Janus Henderson underlying funds, it is subject to certain potential conflicts of interest when allocating the assets of the Funds among Janus Henderson underlying funds. Portfolio management, officers, and Trustees of the Funds may also serve in the same capacity as portfolio management, officers, and Trustees of the Janus Henderson underlying funds. Conflicts may arise as portfolio management, officers, and Trustees seek to fulfill their fiduciary responsibilities to the Funds and the Janus Henderson underlying funds.
Purchases and redemptions of an underlying fund by a Fund due to reallocations or rebalancing may result in an underlying fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the realization of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Fund purchases, redeems, or owns a substantial portion of the underlying fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.
Each Fund invests in underlying funds that may invest substantially all of their assets in common stocks. The main risk associated with investing in those funds is the risk that the value of the stocks they hold might decrease in response to the activities of an individual company or in response to general market and/or economic conditions. If this occurs, an underlying fund’s share price may also decrease.
Each Fund also invests in underlying funds that may invest substantially all of their assets in fixed-income securities or income-generating securities. Investing in this type of underlying fund may expose a Fund to risks such as credit risk and interest rate fluctuations.
A Fund’s performance may also be affected by risks of certain types of investments by the underlying funds. An underlying fund’s performance may also be significantly affected, positively or negatively, by portfolio management’s use of certain types of investments, such as foreign (non-U.S.) securities, derivative investments, ETFs, non-investment grade bonds (also known as “junk” bonds), initial public offerings, or securities of companies with relatively small market capitalizations. Note that portfolio management’s use of such investments may have a magnified performance impact on an underlying fund with a small asset base. In addition, there is a risk that portfolio management may not have the ability to look through to an underlying fund’s investments in connection with monitoring a Fund’s exposure across different asset classes.
The following information is intended to help you better understand some of the risks of investing in the Funds. The impact of the following risks on a Fund may vary depending on the Fund’s investment allocation. The greater a Fund’s allocation to an underlying fund or investment, the greater the Fund’s exposure to the risks associated with that underlying fund or investment. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Authorized Participant Risk.An underlying ETF may have a limited number of financial institutions that may act as Authorized Participants (“APs”). Only APs who have entered into agreements with the underlying ETF’s distributor may engage in creation or redemption transactions directly with the underlying ETF. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the underlying ETF’s shares will be established or maintained. This risk may be heightened to the extent that the securities held by an underlying ETF are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to net asset value and possibly face delisting.
Collateral Risk.With respect to collateral received in repurchase transactions or other investments, an underlying fund may have significant exposure to financial services, mortgage markets, and government agencies not secured by the full faith and credit of the United States. Such exposure, depending on market conditions, could have a negative impact on an underlying fund, including minimizing the value of any collateral.

Counterparty Risk.Underlying fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the underlying fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to an underlying fund. An underlying fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. An underlying fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the underlying fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, an underlying fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of forwards, swaps, futures, and options). To the extent that an underlying fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.Through a Fund’s investments in underlying funds holding fixed-income securities, the Fund is subject to the risks associated with the credit quality of the issuers of those fixed-income securities. Credit quality measures the likelihood that the issuer or borrower will meet its obligations on a bond. One of the fundamental risks for an underlying fund is credit risk, which is the risk that an issuer will be unable to make principal and interest payments when due, or default on its obligations. Higher credit risk may negatively impact an underlying fund’s returns and yield.
Many fixed-income securities receive credit ratings from services such as Standard & Poor’s Rating Services (“Standard & Poor’s”), Fitch, Inc. (“Fitch”), and Moody’s Investors Service, Inc. (“Moody’s”). These services assign ratings to securities by assessing the likelihood of issuer default. The lower a bond issue is rated by an agency, the more credit risk it is considered to represent. Lower rated instruments and securities generally pay interest at a higher rate to compensate for the associated greater risk. Interest rates can fluctuate in response to economic or market conditions, which can result in a fluctuation in the price of a security and impact an underlying fund’s return and yield. If a security has not received a rating, an underlying fund must rely upon an adviser’s credit assessment, which if incorrect can also impact the underlying fund’s returns and yield. Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause an underlying fund to be more volatile than if it had not used leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by an underlying fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent an underlying fund enters into short derivative positions, the underlying fund may be exposed to risks similar to those associated with short sales, including the risk that the underlying fund’s losses are theoretically unlimited.
Emerging Markets Risk.An underlying fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” To the extent that an underlying fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on an underlying fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for an underlying fund to obtain or to enforce a judgment against the issuers of such securities. In addition, an underlying fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the underlying fund’s investments. To the extent that an
33 | Janus Investment Fund

underlying fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the underlying fund’s performance. An underlying fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets. Additionally, foreign and emerging market risks, including but not limited to price controls, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, nationalization, and restrictions on repatriation of assets may be heightened to the extent an underlying fund invests in Chinese or other local market securities.
Emerging market countries in which an underlying fund may invest include frontier market countries, which generally have smaller economies and even less developed capital markets than traditional developing markets, and as a result, the risks of investing in developing market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by other countries; and the relatively new and unsettled securities laws in many frontier market countries.
Equity Securities Risk.The values of equity securities, such as common stocks and preferred stocks, may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than fixed-income securities. These risks are generally magnified in the case of equity investments in distressed companies.
ESG Integration and Investment Risk.Certain underlying funds consider environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) as part of their investment process. There is a risk that considering ESG Factors as part of an underlying fund’s investment process may fail to produce the intended results or that an underlying fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While an underlying fund’s portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which an underlying fund’s portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require an underlying fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
Certain underlying funds have a sustainable or ESG-related strategy, or may employ exclusionary criteria to avoid investing in certain industries, activities, or assets considered by portfolio management to have a negative impact on society or the environment. These underlying funds are subject to similar risks as those underlying funds that consider ESG factors as part of their investment process.
European Investments Risk.Exposure to investments in European countries may expose an underlying fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. An underlying fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.

Exchange-Traded Funds Risk.ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When an underlying fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in an underlying fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds.
Exchange Listing.Shares of an underlying ETF are listed for trading on an exchange; however, there can be no guarantee that an active trading market for such shares will continue or that the underlying ETF’s shares will continue to meet the listing or trading requirements of any exchange.
Fixed-Income Securities Risk.Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that the value of such securities will generally decline as prevailing interest rates rise, which may cause an underlying fund’s net asset value to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities and durations tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates and are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. However, calculations of maturity and duration may be based on estimates and may not reliably predict a security’s price sensitivity to changes in interest rates. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. Investments in fixed-income securities with very low or negative interest rates may diminish an underlying fund’s yield and performance.
Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. In addition, there is prepayment risk, which is the risk that during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause an underlying fund to reinvest its assets in securities with lower yields, resulting in a decline in the underlying fund’s income or return potential. Fixed-income securities may also be subject to valuation risk and liquidity risk. Valuation risk is the risk that one or more of the fixed-income securities in which an underlying fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer of the security. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time that an underlying fund’s portfolio management would like or at the price an underlying fund’s portfolio management believes the security is currently worth. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on an underlying fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk. To the extent an underlying fund invests in fixed-income securities in a particular industry or economic sector, its share values may fluctuate in response to events affecting that industry or sector. Securities underlying mortgage- and asset-backed securities, which may include subprime mortgages, also may be subject to a higher degree of credit risk, valuation risk, and liquidity risk. To the extent that an underlying fund invests in derivatives tied to fixed-income securities, such underlying fund may be more substantially exposed to these risks than an underlying fund that does not invest in such derivatives. The market for certain fixed-income securities may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Similarly, the amount of assets deemed illiquid remaining within such underlying fund may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the underlying fund and the Fund.
Floating Rate Obligations Risk.Certain underlying funds may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Unexpected changes in the interest rates on floating rate obligations could result in lower income to an underlying fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be
35 | Janus Investment Fund

restrictions on their transfer, or that the issuer may default. As a result, an underlying fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Foreign Exposure Risk.Certain underlying funds may invest in foreign equity and/or debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because an underlying fund’s performance may depend on factors other than the performance of a particular company. These factors include:
Currency Risk.As long as an underlying fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When an underlying fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Foreign Market Risk.Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for an underlying fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on an underlying fund. Such factors may hinder an underlying fund’s ability to buy and sell emerging market securities in a timely manner, affecting the underlying fund’s investment strategies and potentially affecting the value of such underlying fund.
Geographic Concentration Risk.To the extent that an underlying fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on an underlying fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on an underlying fund’s performance.
Political and Economic Risk.Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the U.S. Government on other countries or persons or issuers operating in such countries could restrict an underlying fund’s ability to buy affected securities or force an underlying fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, an underlying fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of an underlying fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
36 | Janus Investment Fund

Regulatory Risk.There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
Transaction Costs.Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are bonds rated below investment grade by the primary rating agencies, such as BB+ or lower by Standard & Poor’s and Fitch, or Ba1 or lower by Moody’s, or is an unrated bond of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings. Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Industry and Sector Risk.Although the Funds do not concentrate their investments in specific industries or economic sectors, certain underlying funds may invest, or may have a significant portion of their assets invested in, securities of companies conducting similar business or businesses within the same economic sector. Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. An underlying fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase that underlying fund’s exposure to industry and sector risk.
Inflation Risk.Inflation risk is the risk that the value of certain assets or real income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the present value of an underlying fund’s assets and distributions may decline. This risk may be elevated in a low interest rate environment.
Inflation-Linked Investments Risk.Inflation-linked bonds (including Treasury Inflation-Protected Securities, also known as TIPS), and other inflation-linked securities normally will decline in price when real interest rates rise. In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, inflation-linked bonds may experience greater losses than other fixed-income securities with similar durations. Except for an underlying fund’s investments in TIPS, which are guaranteed as to principal by the U.S. Treasury, the inflation-adjusted principal value or maturity amount of inflation-linked bonds repaid at maturity may be less than the original principal. Because of their inflation-linked adjustment feature, inflation-linked bonds typically have lower yields than conventional fixed-rate securities. In the event of deflation, where prices decline over time, the principal and income of inflation-linked bonds will likely decline, resulting in losses to an underlying fund.
Initial Public Offering and Secondary Offering Risk.A Fund may invest in underlying funds that may purchase shares issued as part of, or a short period after, a company’s initial public offering (“IPO”), and may at times dispose of those shares shortly after their acquisition. An IPO is the first sale of stock by a private company to the public. IPOs are often issued by smaller, younger companies seeking the capital to expand, but can also be done by large privately-owned companies looking to become publicly traded. To the extent a Fund is invested in underlying funds that purchase shares issued in IPOs, the Fund is exposed to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. Attractive IPOs are often oversubscribed and may not be available to the underlying funds in which a Fund invests, or may be available only in very limited quantities. The market for IPO issuers has been volatile, and share prices of newly public companies have fluctuated up and down significantly over short periods of time. There can be no assurance that the underlying funds will identify favorable IPO investment opportunities. In addition, under certain market conditions, a relatively small number of companies may issue securities in IPOs. Similarly, as the number of underlying funds to which IPO securities are allocated increases, the number of securities issued to any one underlying fund may decrease. In addition, as a Fund or underlying fund increases in size, the impact of IPOs on the Fund’s performance will generally decrease.
A Fund may invest in underlying funds that may purchase shares in secondary offerings. Secondary offerings may expose the underlying fund to some of the risks of IPOs. Participation in secondary offerings may have a magnified impact on the performance of an underlying fund to the extent that it has a small asset base and the underlying fund may not experience similar performance as its assets grow. Secondary offering shares frequently are volatile in price. As a result, an underlying
37 | Janus Investment Fund

fund may hold secondary offering shares for a very short period of time. This may increase the portfolio turnover rate of the underlying fund and may lead to increased expenses for the underlying fund, such as commissions and transaction costs. In addition, secondary offering shares can experience an immediate drop in value if the demand for the securities does not continue to support the offering price.
Interest Rate Risk.Generally, a fixed-income security will increase in value when prevailing interest rates fall and decrease in value when prevailing interest rates rise. Longer-term securities are generally more sensitive to interest rate changes than shorter-term securities, but they generally offer higher yields to compensate investors for the associated risks. High-yield bond prices and floating rate debt security prices are generally less directly responsive to interest rate changes than investment grade issues or comparable fixed rate securities, and may not always follow this pattern.
Leverage Risk.Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose an underlying fund to greater risk and increase its costs. The use of leverage may cause an underlying fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act of 1940, as amended, and the rules thereunder. Increases and decreases in the value of an underlying fund’s portfolio will be magnified when the underlying fund uses leverage.
Liquidity Risk.An underlying fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. An underlying fund may also make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, an underlying fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect an underlying fund’s value or prevent such underlying fund from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that an underlying fund invests in restricted securities that are deemed to be illiquid investments.
Loan Risk.Certain underlying funds may invest in various commercial loans, including bank loans, bridge loans, debtor-in-possession (“DIP”) loans, mezzanine loans, and other fixed and floating rate loans. The risks of such investments vary, depending on the type of loans underlying the investments, as described below.
Bank Loan Risk.Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. The bank loans in which an underlying fund may invest may be denominated in U.S. or non-U.S. currencies, including the euro. An underlying fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged or in bankruptcy proceedings. Participation interests and assignments involve credit, interest rate, and liquidity risk. Some participation interests and assignments may not be considered “securities,” and purchasers, such as an underlying fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Additionally, because the Adviser, in the course of investing an underlying fund’s assets in loans, may have access to material non-public information regarding the borrower, the ability of an underlying fund to purchase or sell publicly-traded securities of such borrowers may be restricted. In addition, to the extent an underlying fund invests in non-U.S. bank loan investments, those investments also are subject to the risks of foreign investment, including those described under “European Investments Risk.”
Bridge Loan Risk.Bridge loans are short-term loan arrangements typically made by a borrower in anticipation of receiving intermediate-term or long-term permanent financing. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan increases the longer the loan remains outstanding.
DIP Loan Risk. DIP loans are issued in connection with restructuring and refinancing transactions. DIP loans are loans to a debtor-in-possession in a proceeding under the U.S. bankruptcy code that have been approved by the bankruptcy court. In addition to the risks associated with bank loans, an underlying fund’s investments in bridge loans may subject a Fund to certain risks, including the risk that a borrower may be unable to locate permanent financing to replace the bridge loan,
38 | Janus Investment Fund

which may impair the borrower’s perceived creditworthiness. An underlying fund’s investments in DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets.
Mezzanine Loan Risk.Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations.
Market Risk. The value of an underlying fund’s portfolio may decrease if the value of one or more issuers in the underlying fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of an underlying fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the underlying fund invests. If the value of the underlying fund’s portfolio decreases, an underlying fund’s net asset value will also decrease, resulting in a decrease in a Fund’s net asset value, which means if you sell your shares in the Fund, you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Money Market Fund Investment Risk.An underlying fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, an underlying fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and an underlying fund may lose money. To the extent an underlying fund transacts in instruments such as derivatives, such underlying fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from such underlying fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share net asset value at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable net asset value could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their net asset values. Certain money market funds have in the past failed to maintain stable net asset values, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the SEC require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s net asset value per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating net asset value requirements. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund.
39 | Janus Investment Fund

Recently adopted amendments to Rule 2a-7 also require certain money market funds, excluding Government Money Market Funds and Retail Money Market Funds, to impose mandatory liquidity fees when a fund experiences net redemptions that exceed 5% of net assets, unless the fund’s liquidity costs are de minimis (i.e., less than 1 basis point).
There can be no assurance that an underlying fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
In addition to the fees and expenses that an underlying fund directly bears, an underlying fund indirectly bears the fees and expenses of any money market fund in which it invests.
Mortgage- and Asset-Backed Securities Risk.Rising interest rates tend to extend the duration of, or reduce the rate of prepayments on, both commercial mortgage-backed securities (“CMBS”) and residential mortgage-backed securities (“RMBS”), making them more sensitive to changes in interest rates (“extension risk”). As a result, in a period of rising interest rates, the price of mortgage-backed securities may fall, causing an underlying fund that holds mortgage-backed securities to exhibit additional volatility. Mortgage-backed securities are also subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce an underlying fund’s returns because the underlying fund will have to reinvest that money at lower prevailing interest rates. Investments in certain mortgage-backed securities, including those comprised of subprime mortgages, may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities. Additionally, although mortgage-backed securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that guarantors or insurers will meet their obligations.
CMBS are subject to certain other risks. The market for CMBS developed more recently than that for RMBS and is relatively small in terms of outstanding principal amount of issues compared to the RMBS market. CMBS are also subject to risks associated with a lack of standardized terms, shorter maturities than residential mortgage loans, and payment of all or substantially all of the principal at maturity, rather than regular amortization of principal. Moreover, the type and use of a particular commercial property may add to the risk of CMBS investments. Adverse changes in economic conditions and circumstances are more likely to have an adverse impact on mortgage-backed securities secured by loans on commercial properties than on those secured by residential properties.
Similarly, the value of an underlying fund’s investments in asset-backed securities may be adversely affected by changes in interest rates, factors concerning the interests in and structure of the issuer or originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds, or other credit or liquidity enhancements, and/or the market’s assessment of the quality of the underlying assets. Generally, the originating bank or credit provider is neither the obligor nor the guarantor of the security, and interest and principal payments ultimately depend upon payment of the underlying loans by individuals. An underlying fund could incur a loss if the underlying loans are not paid. In addition, most asset-backed securities are subject to prepayment risk in a declining interest rate environment. The impact of prepayments on the value of asset-backed securities may be difficult to predict and may result in greater volatility. Rising interest rates tend to extend the duration of asset-backed securities, making them more volatile and sensitive to changing interest rates.
Nondiversification Risk.Certain underlying funds may be classified as nondiversified under the Investment Company Act of 1940, as amended. As a result, an increase or decrease in the value of a single security held by an underlying fund may have a greater impact on the underlying fund’s net asset value and total return. Being nondiversified may also make an underlying fund more susceptible to financial, economic, political, or other developments that may impact a security. Although an underlying fund may satisfy the requirements for a diversified fund, its nondiversified classification gives the underlying fund’s portfolio management more flexibility to hold larger positions in more securities than an underlying fund that is classified as diversified.
Portfolio Turnover Risk.Increased portfolio turnover of underlying funds may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on the underlying fund’s performance.
Private Placements and Other Exempt Securities Risk.Investments in private placements and other securities exempt from certain registration requirements could decrease an underlying fund’s liquidity profile or prevent an underlying fund from disposing of them promptly at advantageous prices. Private placements and other securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad
40 | Janus Investment Fund

public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. Transaction costs may be higher for these securities, and an underlying fund may get only limited information about the issuer of a private placement or other security exempt from certain registration requirements.
REIT and Real Estate-Related Securities Risk.To the extent that an underlying fund holds real estate investment trusts (“REITs”) and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which an underlying fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. An underlying fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of an underlying fund’s expenses. The value of investments in real estate operating companies (“REOCs”) will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for an underlying fund, including significantly reducing the return to the underlying fund on its investment in such company.
Secondary Market Trading Risk.The net asset value of an underlying ETF’s shares will generally fluctuate with changes in the market value of the underlying ETF’s securities holdings. However, shares of an underlying ETF trade on a national securities exchange at prices above or below their most recent net asset value. The “market price” for an underlying ETF’s fluctuates continuously throughout the national securities exchange’s trading day based on supply and demand of the underlying ETF’s shares. The market price of an underlying ETF’s shares may not track an underlying ETF’s net asset value, which is only calculated at the end of each business day.
A potential investor in an underlying ETF will likely also incur the cost of the “spread” (the difference between the bid price and the ask price for a share of the underlying ETF). The spread varies over time for shares of an underlying ETF. The cost is generally smaller for underlying ETFs with significant daily trading volumes and larger for underlying ETFs with smaller daily trading volumes.
Additionally, during a “flash crash,” the market price of an underlying ETF’s shares may decline suddenly and significantly, resulting in underlying ETF shares trading at a substantial discount to its net asset value. Such a decline may not reflect the performance of the portfolio securities held by the underlying ETF. Flash crashes may also cause APs and other market makers to limit or cease trading in an underlying ETF’s shares, which may result in a further increase in the variance between market prices of the underlying ETF’s shares and the underlying ETF’s shares’ net asset value. Shareholders could suffer significant losses to the extent that they sell Fund shares during a flash crash.
Securities Lending Risk.An underlying fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When an underlying fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The underlying fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, the underlying fund may lose money. There is also the
41 | Janus Investment Fund

risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the underlying fund may experience delays and costs in recovering the security or gaining access to the collateral provided to collateralize the loan. If the underlying fund is unable to recover a security on loan, the underlying fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the underlying fund. With respect to Janus Henderson underlying funds, the Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Short Sales Risk.Short sales are speculative transactions and involve special risks, including a greater reliance on the ability to accurately anticipate the future value of a security. An underlying fund will suffer a loss if it sells a security short and the value of the security rises rather than falls. An underlying fund’s losses are potentially unlimited in a short sale transaction. The use of short sales may also cause an underlying fund to have higher expenses than those of other underlying funds. In addition, due to the investment process of long and short positions, an underlying fund may be subject to additional transaction costs that may lower the underlying fund’s returns. An underlying fund’s use of short sales may also have a leveraging effect on the underlying fund’s portfolio and may increase losses and volatility of returns.
Sovereign Debt Risk.Certain underlying funds may invest in U.S. and non-U.S. government debt securities (“sovereign debt”). Investments in sovereign debt, especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. An underlying fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the underlying fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the underlying fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent an underlying fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Swap Agreements Risk.Certain underlying funds may utilize swap agreements including, but not limited to, credit default swaps, equity swaps, inflation index swaps, interest rate and currency swaps, total return swaps (including fixed-income total return swaps), and swaps on exchange-traded funds, as a means to gain exposure to certain companies or countries, and/or to “hedge” or protect their portfolios from adverse movements in securities prices, the rate of inflation, or interest rates. Swaps may also be used for capital appreciation. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to the underlying fund. If the other party to a swap defaults, the underlying fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If an underlying fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the underlying fund and reduce the underlying fund’s total return. Various types of swaps such as credit default, equity, interest rate, and total return are described in the “Glossary of Investment Terms.”
TBA Commitments Risk.Certain underlying funds may enter into “to be announced” or “TBA” commitments. Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the underlying fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to an underlying fund may be less favorable than expected. There is a risk that the security that an underlying fund buys will lose value between the purchase and settlement dates. When an underlying fund sells a TBA security prior to settlement, it does not participate in future gains or losses with respect to the security. An underlying fund is generally not required to pay for the TBA security until the settlement date and, as a result, if the underlying fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
42 | Janus Investment Fund

Variable Interest Entities (“VIEs”) Risk.In seeking exposure to Chinese issuers, an underlying fund may invest in VIE structures, which in addition to the risks listed under “Foreign Exposure Risk” and “Emerging Markets Risk,” present additional complexity and risks that may not be present in other organizational structures. VIE structures enable foreign investors, such as an underlying fund, to obtain exposure to a Chinese operating company through a contractual agreement without having equity ownership of such company. The Chinese government could determine at any time, and without notice, that the agreements establishing the VIE structure do not comply with Chinese law and regulations, which could result in potential penalties, revocation of business and operating licenses, or forfeiture of ownership interests. Additionally, because VIEs operate using contractual arrangements rather than having equity ownership, foreign investors do not have rights of direct equity owners including rights to residual profits or control over management.
Volatility Risk.Portfolio management of Janus Henderson Adaptive Risk Managed U.S. Equity Fund, an underlying fund, uses a proprietary methodology that seeks to avoid issuers whose upside volatilities are perceived to be lower and whose downside volatilities are perceived to be higher. There is no guarantee that the underlying fund’s strategy to minimize volatility will be successful. Securities in the underlying fund’s portfolio may be subject to price volatility, and the prices may not be any less volatile than the market as a whole, and could be more volatile. In addition, the underlying fund’s strategy to minimize volatility could limit the underlying fund’s gains in rising markets.

Management of the Funds
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Funds and certain underlying funds (the “Janus Henderson underlying funds”). The Adviser is responsible for the day-to-day management of the Funds’ investment portfolios, as well as the investment portfolios of the Janus Henderson underlying funds, and furnishes continuous advice and recommendations concerning the Funds’ investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Funds.
In addition, the Adviser utilizes a personnel-sharing arrangement with its foreign (non-U.S.) affiliate, Janus Henderson Investors UK Limited (“JHIUKL”), pursuant to which one or more Janus Henderson employees, acting for JHIUKL, may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for JHIUKL, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to the Funds on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of a Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate a Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that a Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to a Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for a Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The terms of the exemptive order that are discussed above may also apply to the Janus Henderson underlying funds because they are managed by the Adviser. Refer to such underlying funds’ prospectuses for additional detail.
The Adviser furnishes certain administration, compliance, and accounting services to the Funds, including providing office space for the Funds and providing personnel to serve as officers to the Funds. The Adviser generally pays the salaries, fees, and expenses of Fund officers with respect to services provided to the Funds, although some expenses related to compensation payable to the Funds’ Chief Compliance Officer and compliance staff are shared with the Funds.
Management expenses
Each Fund pays the Adviser an investment advisory fee and incurs expenses, including the distribution and shareholder servicing fees (12b-1 fee), administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay. The Adviser also receives an investment advisory fee for managing the Janus Henderson underlying funds. Refer to such underlying funds’ prospectuses for specific information about investment advisory fees.

For the fiscal year ended June 30, 2024, the Fund did not pay any compensation to the Adviser (net of fee waivers) because the Fund’s fee waiver exceeded the investment advisory fee.
A discussion regarding the basis for the Trustees’ approval of the Funds’ investment advisory agreements is included in each Fund’s semiannual report (for the period ended December 31, 2023) and in the Funds’ financial statements (for the period ended June 30, 2024, and moving forward). You can request the Funds’ semiannual reports or financial statements (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus Henderson representative at 1-877-335-2687. This information is also available, free of charge, at janushenderson.com/info.
Expense Limitations
The Adviser has contractually agreed to waive the advisory fee payable by each Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding any expenses of an underlying fund (acquired fund fees and expenses), the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below. The Adviser has agreed to continue each waiver for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. For information about how the expense limit affects the total expenses of each Fund, if applicable, see the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus.

Other information
CLOSED FUND POLICIES
A Fund may limit sales of its Shares to new investors. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Funds
The Funds are distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Funds, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within a single Fund. Distributions by the underlying funds and changes in asset allocations may result in taxable distributions of ordinary income or capital gains.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well. The date you receive your distribution may vary depending on how your intermediary processes trades. Please consult your intermediary for details.
How Distributions Affect a Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund without any sales charge. To receive distributions in cash, contact your financial intermediary. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Funds. The following is a general discussion of certain federal income tax consequences of investing in the Funds. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of a
48 | Janus Investment Fund

Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of an underlying fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, an underlying fund that invests in REITs is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than an underlying fund that does not invest in REITs.
Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of a Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Funds may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), a Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary will report cost basis information to you and to the IRS. Your intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If a Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.

Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s guide
With certain exceptions, the Funds are generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Funds require that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with a Fund.
The Funds offer multiple classes of shares in order to meet the needs of various types of investors.
Class A Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. Class A Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services on behalf of their clients. In addition, Class A Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. Class A Shares may be offered without an initial sales charge to certain classes of investors such as purchases through certain retirement platforms, certain self-directed brokerage platforms where the financial intermediary is the broker of record, or fee-based platforms. See “Qualifying for a Waiver or Reduction of Class A Shares Sales Charge” in this Shareholder’s Guide for additional details.
Class C Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, and bank trust platforms. Class C Shares pay up to 0.75% of net assets for payment to financial intermediaries for the provision of distribution services and up to 0.25% of net assets for the provision of shareholder services on behalf of their clients. In addition, Class C Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class C Shares are closed to investments by new employer-sponsored retirement plans and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares. Other share classes described in this Prospectus as eligible for investment by retirement plans are unaffected by this closure.
Class C Shares currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares. For more information, please refer to “Conversion of Class C Shares to Class A Shares.”
Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class S Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. Class I Shares may also be available to retail investors purchasing in qualified or nonqualified accounts where such accounts are held through an omnibus account at your broker or financial intermediary. For more information please refer to Appendix B which accompanies this Prospectus. Class I Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. In addition to these fees and expenses paid by Class I Shares, your broker or financial intermediary may impose a commission or other sales charge on purchases. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative.
Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class T Shares pay up to 0.25% of net assets to
51 | Janus Investment Fund

financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
The Shares are not offered directly to individual investors. Consult with your financial intermediary representative for additional information on whether the Shares are an appropriate investment choice. Certain funds may not be available through certain of these intermediaries and not all financial intermediaries offer all classes of shares. If your financial intermediary offers more than one class of shares, you should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. For instructions on how to purchase, exchange, or redeem Shares, contact your financial intermediary or refer to your plan documents.
Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The value of a Fund’s investment in an underlying mutual fund is based upon the NAV of such underlying mutual fund. The value of a Fund’s investment in an underlying ETF is generally based on the closing prices of such underlying ETF at the applicable exchange. A Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which a Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by an underlying fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.
The price you pay for purchases of Shares is the public offering price, which is the NAV next calculated after your request is received in good order by a Fund or its agents, plus, for Class A Shares, any applicable initial sales charge. The price you pay to sell Shares is also the NAV, although for Class A Shares and Class C Shares, a contingent deferred sales charge may be taken out of the proceeds. For Class I Shares, although purchases and redemptions are made at the net asset value calculated after your order is received by the Funds, you may be charged a commission by your broker or other financial institution. The nature and amount of the commission and the times at which it may be collected are determined by your broker. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares. In order to receive a day’s price, your order must be received in good order by a Fund or its agents by the close of the trading session of the NYSE.
Janus Henderson underlying fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The
52 | Janus Investment Fund

Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing underlying fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security of a non-money market underlying fund may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of an underlying fund’s portfolio securities and the reflection of such change in a Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While underlying funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in underlying funds which do not invest in foreign securities, for example, when trading in a security held by an underlying fund is halted and does not resume prior to the time the underlying fund calculates its NAV (referred to as “stale pricing”). Underlying funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of an underlying fund may dilute the NAV of that underlying fund, which negatively impacts long-term shareholders of the underlying fund. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Funds under the arrangements made between your financial intermediary or plan sponsor and its customers. The Funds are not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Choosing a share class
Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class T Shares are offered by this Prospectus. The Funds offer multiple classes of shares in order to meet the needs of various types of investors. For more information about these classes of Shares and whether or not you are eligible to purchase these Shares, please call 1-877-335-2687.
Each class represents an interest in the same portfolio of investments, but has different charges and expenses, allowing you to choose the class that best meets your needs. For an analysis of fees associated with an investment in each share class or other similar funds, please visit www.finra.org/fundanalyzer. When choosing a share class, you should consider:
how much you plan to invest;
how long you expect to own the shares;
the expenses paid by each class; and
for Class A Shares and Class C Shares, whether you qualify for any reduction or waiver of any sales charges.

(3) 
In addition to these fees and expenses, your broker or financial intermediary may impose a commission or other sales charge on your purchases of Class I Shares.

(4) 
Exceptions to this minimum may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts.
Distribution, servicing, and administrative fees
Distribution and Shareholder Servicing Plans
Under separate distribution and shareholder servicing plans adopted in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended, for Class A Shares and Class S Shares (each a “Plan”) and Class C Shares (the “Class C Plan”), each Fund pays the Distributor a fee for the sale and distribution and/or shareholder servicing of the Shares based on the average daily net assets of each, at the following annual rates:
Class
12b-1 Fee for the Funds
Class A Shares
0.25%
Class C Shares
1.00%(1)
Class S Shares
0.25%
(1) 
Up to 0.75% of this fee is for distribution services and up to 0.25% of this fee is for shareholder services.
Under the terms of each Plan, the Trust is authorized to make payments to the Distributor for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Funds.
The Distributor is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although the Distributor may, pursuant to a written agreement between the Distributor and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.
Financial intermediaries may from time to time be required to meet certain criteria in order to receive 12b-1 fees. The Distributor is entitled to retain some or all fees payable under each Plan in certain circumstances, including when there is no broker of record or when certain qualification standards have not been met by the broker of record.
Because 12b-1 fees are paid out of a Fund’s assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.
Administrative Fees
Class A Shares, Class C Shares, and Class I Shares
Certain, but not all, intermediaries may charge fees for administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided by intermediaries on behalf of
55 | Janus Investment Fund

shareholders of the Funds. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent pays these administrative fees to intermediaries on behalf of the Funds. The Transfer Agent is then reimbursed by the Funds for such payments. Because the form and amount charged varies by intermediary, the amount of the administrative fee borne by the class is an average of all fees charged by intermediaries. In the event an intermediary receiving payments from the Transfer Agent on behalf of the Funds converts from a networking structure to an omnibus account structure, or otherwise experiences increased costs, fees borne by the Shares may increase. The Funds’ Trustees have set limits on fees that the Funds may incur with respect to administrative fees paid for omnibus or networked accounts. Such limits are subject to change by the Trustees in the future.
Class S Shares and Class T Shares
The Transfer Agent receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class S Shares and Class T Shares of each Fund for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds. Order processing includes the submission of transactions through the NSCC or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent expects to use all or a significant portion of this fee to compensate intermediaries and retirement plan service providers for providing these services to their customers who invest in the Funds. The Transfer Agent or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to the Funds.
For all share classes, the Transfer Agent also seeks reimbursement for costs it incurs as transfer agent and for providing servicing.
Payments to financial intermediaries by the Adviser or its affiliates
From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries that sell certain classes of Shares of the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Sales- and asset-based payments currently range up to 25 basis points on sales and up to 20 basis points on average annual net assets of shares held through the intermediary and are subject to change. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus Henderson funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Payments made with respect to certain classes of Shares may create an incentive for an intermediary to promote or favor other share classes of the Janus Henderson funds. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries, including, but not limited to, the share class or share classes selected by the financial intermediary for a particular channel, platform or investor type, whether such class is open to new investors on a particular platform or channel, the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness of the intermediary to cooperate with the Adviser’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors may change from time to time. Broker-dealer firms currently receiving or expected to receive these fees are listed in the SAI.
In addition, the Adviser, the Distributor, or their affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the NSCC or other means), and the Committee on
56 | Janus Investment Fund

Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services.
The Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments, reimbursements, and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. However, as described elsewhere in this Prospectus, your financial adviser and/or his or her firm may also receive 12b-1 fees and/or administrative services fees in connection with your purchase and retention of Janus Henderson funds. When such fees are combined with the payments described above, the aggregate payments being made to a financial intermediary may be substantial. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
Purchases of Shares may generally be made only through institutional channels such as financial intermediaries and retirement platforms. Contact your financial intermediary or refer to your plan documents for information on how to invest in each Fund, including additional information on minimum initial or subsequent investment requirements. Under certain circumstances, a Fund may permit an in-kind purchase of Shares. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Funds’ behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Funds or that provide services in connection with investments in the Funds. You should consider such arrangements when evaluating any recommendation of the Funds.
57 | Janus Investment Fund

Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Minimum Investment Requirements
Class A Shares, Class C Shares, Class S Shares, and Class T Shares
The minimum investment is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. In addition, shares held through certain supermarket and/or self-directed brokerage accounts, or through wrap programs, may not be subject to these minimums. Investors should refer to their intermediary for additional information.
The maximum purchase in Class C Shares is $500,000 for any single purchase. The sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $500,000 of Fund shares. Effective on or about December 9, 2024, the maximum purchase in Class C Shares will change to $250,000 for any single purchase. At that time, the sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $250,000 of Fund shares.
Class I Shares
Accounts offered through an intermediary institution must meet the minimum investment requirements of $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Directors, officers, and employees of Janus Henderson Group plc (“JHG”) and its affiliates, as well as Trustees and officers of the Funds, may purchase Class I Shares through certain financial intermediaries’ institutional platforms. For more information about this program and eligibility requirements, please contact a Janus Henderson representative at 1-800-333-1181. Exceptions to these minimums may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts. For additional information, contact your intermediary, plan sponsor, or administrator, as applicable.
Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class T Shares
Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Each Fund reserves the right to change the amount of these minimums or maximums from time to time or to waive them in whole or in part.

Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Initial Sales Charge
Class A Shares
An initial sales charge may apply to your purchase of Class A Shares of the Funds based on the amount invested, as set forth in the table below. The sales charge is allocated between the Distributor and your financial intermediary. Sales charges, as expressed as a percentage of offering price and as a percentage of your net investment, are shown in the table. The dollar amount of your initial sales charge is calculated as the difference between the public offering price and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding.

Effective on or about December 9, 2024, for purchases of Class A Shares of $250,000 or greater, from its own assets, the Distributor generally pays financial intermediaries commissions as follows:
1.00% on amounts of $250,000 but under $4,000,000;
0.50% on amounts of $4,000,000 but under $10,000,000;
0.25% on amounts of $10,000,000 and above.
The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.
Qualifying for a Waiver or Reduction of Class A Shares Sales Charge
Class A Shares of the Funds may be purchased without an initial sales charge by the following persons (and their family members): (i) registered representatives and other employees of intermediaries that have selling agreements with the Distributor to sell Class A Shares; (ii) directors, officers, and employees of JHG and its affiliates; and (iii) Trustees and officers of the Trust. A “family member” includes, but is not necessarily limited to (based on the reasonable discretion of the Adviser), a qualifying person’s sibling, spouse or domestic partner, lineal ascendant (mother, father, grandmother, grandfather, great-grandmother, great-grandfather), lineal descendant (son, daughter, step-son, step-daughter, grandson, granddaughter, great-grandson, great-granddaughter) or any sibling, spouse or domestic partner of a family member who is a lineal descendant or ascendant of a qualifying person. In addition, the initial sales charge may be waived on purchases of Class A Shares by the following persons: (i) investors purchasing Class A Shares through financial intermediaries on behalf of certain adviser-assisted, employer-sponsored retirement plans, including defined contribution plans, defined benefit plans and other welfare benefit plans such as health savings accounts and voluntary employees’ beneficiary association trust accounts; (ii) investors purchasing Class A Shares through a financial intermediary’s self-directed brokerage platform where the financial intermediary is the broker of record; and (iii) investors purchasing Class A Shares through fee-based broker-dealers or financial advisors, primarily on their advisory account platform(s) where such broker-dealer or financial advisor imposes additional fees for services connected to the advisory account. Adviser-assisted, employer-sponsored defined contribution plans include, for example, 401(k) plans, 457 plans, 403(b) plans, profit sharing and money purchase pension plans. For purposes of qualifying for a waiver of the initial sales charge, the following retirement accounts are not eligible: 403(b) custodial accounts where shares are held on behalf of the individual, and not on behalf of the plan or plan trust, SEP IRAs, Simple IRAs, SAR-SEPs, or Keogh plans. To facilitate the waiver of a sales charge, the Distributor requires an agreement with the financial intermediary submitting trades on behalf of eligible investors.
You may be able to lower your Class A Shares sales charge under certain circumstances. For example, you can combine Class A Shares and Class C Shares you already own (either in these Funds or certain other Janus Henderson funds) with your current purchase of Class A Shares of the Funds and certain other Janus Henderson funds (including Class C Shares of those funds) to take advantage of the breakpoints in the sales charge schedule as set forth above. Certain circumstances under which you may combine such ownership of Shares and purchases are described below. Contact your financial intermediary for more information.
In order to obtain a sales charge discount, you should inform your financial intermediary of other accounts in which there are Fund holdings eligible to be aggregated to meet a sales charge breakpoint. These other accounts may include the accounts described under “Aggregating Accounts.” You may need to provide documents such as account statements or confirmation statements to prove that the accounts are eligible for aggregation. The Letter of Intent described below requires historical cost information in certain circumstances. You should retain records necessary to show the price you paid to purchase Fund shares, as the Funds, their agents, or your financial intermediary may not retain this information.
Right of Accumulation.You may purchase Class A Shares of a Fund at a reduced sales charge by aggregating (i) the dollar amount of the new purchase (measured by the offering price) with (ii) your holdings in all Class A Shares of the Fund and certain other classes (Class A Shares and Class C Shares of the Trust) of Janus Henderson funds held by you, and held in the accounts identified under “Aggregating Accounts” (“collective holdings”). Subject to your financial intermediary’s or record keeper’s capabilities, collective holdings will be calculated as the higher of (i) the current value of such holdings (the market value) as of the day prior to your new purchase or (ii) the amount initially invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the cost value). The applicable sales charge will be applied to such aggregated amount. In order for your purchases and collective holdings to be aggregated for purposes of qualifying for a reduced sales charge, they must have been made through one financial intermediary and you must provide sufficient information to your financial intermediary at the time of purchase to permit verification that the purchase qualifies
60 | Janus Investment Fund

for the reduced sales charge. The qualification of a purchase for the reduced sales charge does not ensure the future availability of the right of accumulation, which is subject to modification or discontinuance at any time.
Letter of Intent.You may obtain a reduced sales charge on Class A Shares by signing a Letter of Intent indicating your intention to purchase $50,000 or more of Class A Shares (including Class A Shares in other series of the Trust) over a 13-month period. The term of the Letter of Intent will commence upon the date you sign the Letter of Intent. Investments made prior to the signing date are not aggregated with, and are not eligible to be included toward, the investment goal.
You must refer to such Letter when placing orders. With regard to a Letter of Intent, the amount of investment for purposes of applying the sales load schedule includes (i) the historical cost (what you actually paid for the shares at the time of purchase, including any sales charges) of all Class A Shares acquired during the term of the Letter of Intent, minus (ii) the value of any redemptions of Class A Shares made during the term of the Letter of Intent. Capital appreciation, capital gains, and reinvested dividends earned during the Letter of Intent period do not apply toward its completion. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. A portion of shares purchased may be held in escrow to pay for any sales charge that may be applicable. If the goal is not achieved within the period, you must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed. Please contact your financial intermediary to obtain a Letter of Intent application.
Aggregating Accounts.To take advantage of lower Class A Shares sales charges on large purchases or through the exercise of a Letter of Intent or right of accumulation, investments made by you, your spouse, and your children under age 21 may be aggregated if made for your own account(s) and/or certain other accounts such as:
trust accounts established by the above individuals (or the accounts of the primary beneficiary of the trust if the person who established the trust is deceased);
solely controlled business accounts; and
single participant retirement plans.
To receive a reduced sales charge under rights of accumulation or a Letter of Intent, you must notify your financial intermediary of any eligible accounts that you, your spouse, and your children under age 21 have at the time of your purchase.
You may access information regarding sales loads, breakpoint discounts, and purchases of the Funds’ shares, free of charge, and in a clear and prominent format, on our website at janushenderson.com/breakpoints, and by following the appropriate hyperlinks to the specific information.
Conversion of Class C Shares to Class A Shares
The Funds currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month of the eighth anniversary of the date of purchase. Class C Shares purchased through the reinvestment of dividends and other distributions on Class C Shares will convert to Class A Shares at the same time as the Class C Shares with respect to which they were purchased.
For Class C Shares held in omnibus accounts on intermediary platforms, the Funds will rely on these intermediaries to implement this conversion feature. Your financial intermediary may have separate policies and procedures as to when and how Class C Shares may be converted to Class A Shares. Please contact your financial intermediary for additional information.
It is expected that the conversion of Class C Shares to Class A Shares of the same Fund will not result in a taxable event. Please consult your tax adviser for further information.
Commission on Class C Shares
The Distributor may compensate your financial intermediary at the time of sale at a commission rate of 1.00% of the net asset value of the Class C Shares purchased. Service providers to financial intermediaries will not receive this amount if they receive 12b-1 fees from the time of initial investment of assets in Class C Shares.
Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (“CDSC”) waivers. In all instances, it is the shareholder’s responsibility to notify a
61 | Janus Investment Fund

Fund, or the shareholder’s financial intermediary at the time of purchase, of any relationship or other facts qualifying the shareholder for sales charge waivers or discounts. Certain sales charge waivers and/or discounts are described in Appendix B – Intermediary Sales Charge Waivers and Discounts. These sales charge waivers and/or discounts are available only if you purchase your shares through the designated intermediaries. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares through another intermediary to receive these waivers or discounts.
Exchanges
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Contact your financial intermediary or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received. A Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
You must meet the minimum investment amount for each fund.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds will work with intermediaries to apply the Funds’ exchange limits. However, the Funds may not always have the ability to monitor or enforce the trading activity in such accounts.
Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Class C Shares are closed to investments by new employer-sponsored retirement plans, and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares.
Your Class C Shares that have been held for eight years will automatically convert to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month in which the eighth anniversary of the date of purchase occurs. For more information refer to “Conversion of Class C Shares to Class A Shares.”
Waiver of Sales Charges
Class A Shares received through an exchange of Class A Shares of another fund of the Trust will not be subject to an initial sales charge. In addition, Class A Shares received through an exchange of Class C Shares due to an intermediary-driven conversion or an automatic conversion after eight years, or a conversion from a fee-based account to a brokerage account, will not be subject to an initial sales charge. Class A Shares or Class C Shares received through an exchange of Class A Shares or Class C Shares, respectively, of another fund of the Trust will not be subject to any applicable CDSC at the time of the exchange. CDSC applicable to redemptions of Class A Shares or Class C Shares will continue to be measured on the Shares received by exchange from the date of your original purchase. For more information about the CDSC, please refer to “Redemptions.” While Class C Shares do not have any front-end sales charges, their higher annual fund operating expenses mean that over time, you could end up paying more than the equivalent of the maximum allowable front-end sales charge.
62 | Janus Investment Fund

Redemptions
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Funds.
Redemptions, like purchases, may generally be effected only through financial intermediaries, and retirement platforms. Please contact your financial intermediary or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of each Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by a Fund or its agents. Redemption proceeds, less any applicable CDSC for Class A Shares or Class C Shares, will normally be sent within two business days following receipt of the redemption order. The Funds typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s or underlying fund’s shares. Redemptions by these large shareholders of their holdings may cause a Fund or underlying fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large purchases may adversely affect a Fund’s or underlying fund’s performance to the extent that the Fund or underlying fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s or underlying fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If a Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
63 | Janus Investment Fund

While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Systematic Withdrawal Plan
Class A Shares and Class C Shares
You may arrange for periodic redemptions of Class A Shares or Class C Shares by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Any resulting CDSC may be waived, however, the maximum annual rate at which shares subject to a CDSC may be redeemed, pursuant to a systematic withdrawal plan, without paying a CDSC, is 12% of the net asset value of the account. Certain other terms and minimums may apply. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Class S Shares, Class I Shares, and Class T Shares
You may arrange for periodic redemptions by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Contingent Deferred Sales Charge
Class A Shares and Class C Shares
A 1.00% CDSC may be deducted with respect to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase, unless any of the CDSC waivers listed apply. A 1.00% CDSC will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless a CDSC waiver applies. The CDSC will be based on the lower of the original purchase price or the value of the redemption of the Class A Shares or Class C Shares redeemed, as applicable.
CDSC Waivers
There are certain cases in which you may be exempt from a CDSC charged to Class A Shares and Class C Shares. Among others, these include:
Upon the death or disability of an account owner;
Retirement plans and certain other accounts held through a financial intermediary where no sales charge or commission was paid on the purchase of such shares;
Retirement plan shareholders taking required minimum distributions;
The redemption of Class A Shares or Class C Shares acquired through reinvestment of Fund dividends or distributions;
The portion of the redemption representing appreciation as a result of an increase in NAV above the total amount of payments for Class A Shares or Class C Shares during the period during which the CDSC applied; or
If a Fund chooses to liquidate or involuntarily redeem shares in your account.
To keep the CDSC as low as possible, Class A Shares or Class C Shares not subject to any CDSC will be redeemed first, followed by shares held longest.
Reinstatement Privilege
For each redemption of Class A Shares, you have a one-time right to reinvest the proceeds of such redemption into Class A Shares of the same or another fund within 90 days of the redemption date at the current NAV (without an initial sales charge). You will not be reimbursed for any CDSC paid on your redemption of Class A Shares.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Funds are intended for long-term investment purposes, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or
64 | Janus Investment Fund

excessive trading policies and procedures may be cancelled or rescinded by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Funds are also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Funds monitor for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds at all times reserve the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund.
The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.
In an attempt to deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Funds’ excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Funds by a collective investment trust managed by the Adviser; (iv) transactions in the Funds by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.
Excessive Trading Risks
Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Underlying funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by an underlying fund, which, in turn, may be held by a Fund, based on events occurring after the close of a foreign market that may not be reflected in the underlying fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in underlying funds which do not invest in foreign securities, for example, when trading in a security held by an underlying fund is halted and does not resume prior to the time the underlying fund calculates its NAV (referred to as “stale pricing”). Underlying funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the underlying fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of the underlying fund or a Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by an underlying fund despite the underlying funds’
65 | Janus Investment Fund

adoption of policies and procedures intended to reduce the underlying fund’s exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Funds to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of each Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for each Fund at janushenderson.com/info. A complete schedule of each Fund’s portfolio holdings is also available in the annual and semiannual financial statements included in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. Each Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Funds’ Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.
Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor is responsible for providing annual and semiannual reports of the Funds that you have authorized for investment. Please contact your financial intermediary or plan sponsor to obtain these reports. The Funds’ fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed
66 | Janus Investment Fund

property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
67 | Janus Investment Fund

Financial highlights
The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if applicable. The information for the Funds for the fiscal periods ended June 30 has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in each Fund’s Form N-CSR and is incorporated by reference into the SAI. The information in the financial highlights for the six months ended December 31, 2023 is unaudited and is also incorporated by reference into the SAI.
The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in the Shares of the Funds (assuming reinvestment of all dividends and distributions).

Appendix A – investment objectives and strategies of the janus henderson underlying funds
The following information provides a brief description of the investment objectives and strategies of the Janus Henderson underlying funds that are available. Additional details are available in the underlying funds’ prospectuses. The Trustees of the underlying funds may change the investment objectives or strategies of the underlying funds at any time without prior notice to Fund shareholders.
The Funds may allocate assets to all or some of these underlying funds when rebalancing the Funds’ investments. At the discretion of the Adviser and without shareholder notice, the Funds may invest in additional funds established in the future.
Janus Henderson Absolute Return Income Opportunities Fund seeks to maximize total return, consistent with preservation of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. For purposes of this 80% policy, the term bonds refers to a variety of fixed-income securities and instruments, and includes, but is not limited to, such investments as government notes and bonds, corporate bonds, convertible securities, commercial paper, commercial and residential mortgage-backed securities, asset-backed securities, collateralized loan obligations, fixed rate notes, floating rate securities, and derivatives such as forwards, swap agreements, futures contracts, and options that provide exposure to various fixed-income instruments (“Fixed-Income Instruments”). The fund may invest a significant portion of its assets in certain types of Fixed-Income Instruments, including mortgage-backed securities. In pursuing its investment objective, the fund will have exposure to investments that are economically tied to a number of countries throughout the world. The fund seeks to achieve positive returns that exceed its benchmark index in a variety of market environments. The fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income, while at the same time seeking to provide low volatility. The fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed-income market. For example, portfolio management may favor investments in smaller countries or regions that tend to be underrepresented in fixed-income indices that are more heavily focused on the United States or other larger regions globally.
Janus Henderson Adaptive Risk Managed U.S. Equity Fund seeks long-term growth of capital. The fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. companies, including, but not limited to, common stocks and depositary receipts. Under normal circumstances, the fund seeks to achieve returns with lower volatility over a full market cycle than the Russell 1000® Index (the fund’s broad-based benchmark index). The fund seeks to generate such returns with volatility that can range from approximately 0% to 40% lower than the Russell 1000 Index. In this context, volatility refers to the variation in the returns of the fund and the broad-based benchmark index as measured by the standard deviation of monthly returns. The market capitalization of issuers within the broad-based benchmark index, from which the fund’s investment universe is derived, will vary, but as of June 30, 2024, they ranged from approximately $170 million to $3.32 trillion.
Janus Henderson Balanced Fund seeks long-term capital growth, consistent with preservation of capital and balanced by current income. The fund pursues its investment objective by normally investing 35-70% of its assets in equity securities and the remaining assets in fixed-income securities and cash equivalents. The fund normally invests at least 25% of its assets in fixed-income senior securities. The fund’s equity investments include, but are not limited to, common stocks and other securities with equity characteristics. The fund’s fixed-income investments include, but are not limited to, government notes and bonds, corporate bonds, commercial and residential mortgage-backed securities, and asset-backed securities. The fund may also invest in money market instruments. The fund may invest in fixed and floating rate obligations with varying durations. The fund will limit its investments in high-yield bonds (also known as “junk” bonds) to 35% of the fixed-income portion of its net assets. The fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The fund also invests in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. The fund may also invest in foreign securities, which may include investments in emerging market securities.
Janus Henderson Contrarian Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities with the potential for long-term growth of capital. The fund normally invests in a portfolio of 35-55 common stocks. Portfolio management seeks to invest in companies where the stock price trades at a significant discount to portfolio management’s estimate of fair value and whose intrinsic value the portfolio management believes will grow over time. The fund may invest in companies of any size, from larger, well-established companies to smaller, emerging growth companies. The fund may also invest in fixed-income instruments, such as convertible securities and preferred stock. The fund may invest in foreign securities.

Janus Henderson Corporate Bond ETF seeks total return consisting of income and capital appreciation, while giving special consideration to certain ESG factors. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. dollar denominated corporate bonds and commercial paper of various maturities. Under normal circumstances, no more than 15% of the fund’s net assets will be invested in securities rated below investment grade; however, such bonds will have a minimum rating of B- by a Nationally Recognized Statistical Ratings Organization or, if unrated, determined to be of comparable credit quality by the Adviser. The fund may invest up to 20% of its net assets in other domestic or foreign debt securities, including U.S. Treasuries, bank loans, and cash and cash alternatives. The fund may concentrate its portfolio investments in any one industry or group of industries under certain circumstances. Generally, the fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the fund’s performance benchmark at the time of investment, the fund may invest up to 35% of its total assets in that industry. The fund may use derivatives, including, but not limited to, swaps (including interest-rate swaps, total rate of returns swaps and credit default swaps), swaptions, options, futures, and options on futures, which may be used for risk, duration and yield-curve management, or to enhance expected returns. Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, interest rates, currencies, or market indices. The fund may enter into reverse-repurchase agreements and use the proceeds to invest in securities consistent with the fund’s principal investment strategies. The fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
Janus Henderson Developed World Bond Fund seeks total return through current income and capital appreciation. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds or other income-producing debt-related securities from developed countries. The fund considers “developed countries” to include, but not be limited to, those countries characterized as developed by the MSCI World Indexsm, including the United States, United Kingdom, Canada, Australia, Sweden, Denmark, Japan, Austria, Belgium, Finland, France, Germany, New Zealand, the Netherlands, and Switzerland, or such other countries as portfolio management deems to be developed. Under normal circumstances, portfolio management intends to invest at least 40% of the fund’s net assets outside of the United States and in at least three different countries. The fund may also invest up to 20% of its net assets in equity and equity-related securities such as convertibles and debt securities with warrants. While the fund has no policy limiting the currency in which foreign securities may be denominated, the fund seeks to hedge its non-dollar investments back to the U.S. dollar. Securities in which the fund may invest include: all types of bonds, debentures, mortgage-related and other asset-backed securities, investment grade debt securities (including corporate debt, developed market government bonds and U.S. Government securities), high yield securities (also known as “junk” bonds), foreign securities, subordinated bank debt, collective investment schemes, domestic or foreign floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. Portfolio management may shift the fund’s assets among various types of income-producing securities based upon changing market conditions. The fund’s average portfolio duration normally may range from zero to plus nine years. Portfolio management may lengthen or shorten the fund’s duration based on their outlook on interest rates and inflation. The fund may invest in issuers of any credit quality. The fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
Janus Henderson Emerging Markets Fund seeks long-term growth of capital.

securities of issuers that are economically tied to emerging markets countries, including frontier markets countries. Emerging market countries consist of countries included in the International Monetary Fund list of Emerging and Developing Economies.
Janus Henderson Enterprise Fund seeks long-term growth of capital. The fund pursues its investment objective by investing primarily in common stocks selected for their growth potential, and normally invests at least 50% of its equity assets in medium-sized companies. The fund considers medium-sized companies to be those whose market capitalization falls within the range of companies in the Russell Midcap® Growth Index. The market capitalizations within the index will vary, but as of September 30, 2023, they ranged from approximately $223 million to $48.89 billion. The fund may also invest in foreign securities.
Janus Henderson European Focus Fund seeks long-term capital appreciation primarily through investment in equities of European companies.

The fund generally invests in a portfolio of 35-60 equity securities. Equity securities include common stocks and related securities. Portfolio management seeks investments that will increase in value by emphasizing stock selection. Stock selection is based on an opportunistic approach which seeks to utilize stock specific criteria and global market and industry dynamics that are expected to drive stock prices of European companies. Portfolio management will invest in both “growth” stocks that portfolio management believes are reasonably priced and “value” stocks that are, in portfolio management’s opinion, undervalued.
Janus Henderson Flexible Bond Fund seeks to obtain maximum total return, consistent with preservation of capital. The fund pursues its investment objective by primarily investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds.

The fund may invest in fixed and floating rate obligations with varying durations. The fund’s average portfolio duration typically ranges between three and seven years. The fund will invest at least 65% of its net assets in investment grade debt securities. The fund will limit its investment in high-yield bonds to 35% or less of its net assets. The fund generates total return from a combination of current income and capital appreciation, but income is usually the dominant portion. The fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The fund also invests in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. The fund may also invest in foreign securities.

The fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of income-producing equity securities, such as common and preferred dividend-paying stocks. The fund invests in U.S. and non-U.S. issuers and will typically invest at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. The fund has no specific policy on the number of different countries in which it will invest but intends to invest in at least three different countries. In selecting investments, portfolio management primarily seeks to identify companies with attractive long-term business prospects that generate cash and produce attractive levels of dividend income, and which are, in the opinion of portfolio management, undervalued or inexpensive relative to other similar investments. Security selection will be based upon an analysis of a broad range of metrics, including price to earnings ratios, balance sheet strength, valuation relative to asset values, return on equity, and a particular focus on cash flow generation and ability to service growing dividend streams in the medium term.

In the fund’s pursuit of companies with a life science orientation, the fund has a fundamental policy to normally invest at least 25% of its total assets in
85 | Janus Investment Fund

securities of companies that are categorized in the “life sciences” sector, which may include companies in the following industry groups: pharmaceuticals; biotechnology; health care services; agriculture; cosmetics/personal care; and medical devices. Generally speaking, the “life sciences” relate to maintaining or improving quality of life. So, for example, companies with a “life science orientation” include companies engaged in research, development, production, or distribution of products or services related to health and personal care, medicine, or pharmaceuticals. The fund implements its investment policies by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The fund normally invests in issuers from several different countries, which may include the United States. The fund may, under unusual circumstances, invest in a single country.

The fund may invest in shares of companies through initial public offerings and secondary offerings. As a fundamental policy, the fund will concentrate 25% or more of its net assets in securities of issuers in real estate or real estate-related industries. The fund’s investment in companies engaged in businesses outside the real estate industry which possess significant real estate holdings will be deemed to be in the real estate industry for purposes of the fund’s investment objective and its policy on industry concentration. The fund also invests in non-U.S. real estate and real estate-related companies. The fund expects under normal market conditions to maintain investments in issuers that are economically tied to different countries throughout the world, including the United States.

The fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. Because the fund’s investments in foreign securities are partially based on the composition of the fund’s benchmark index, the MSCI World Index, the fund’s exposure to foreign markets may fluctuate in connection with variations in the foreign exposure of the fund’s benchmark index.
Janus Henderson Global Select Fund seeks long-term growth of capital. The fund pursues its investment objective by normally investing in a portfolio of 40-65 domestic and foreign common stocks selected for their growth potential and normally investing at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States.

The fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States. The fund’s investments may be in non-U.S. currency or U.S. dollar-denominated. The fund generally invests in a core group of 50-70 equity securities, which consist primarily of common stocks, but may also include other types of instruments, such as depositary receipts and warrants. The fund may also invest in REITs. The fund will invest primarily in larger, well-established companies but may also invest in mid- and small-sized companies. The fund’s uninvested assets may be held in cash or cash equivalents.
Janus Henderson Global Technology and Innovation Fund seeks long-term growth of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies that portfolio management believes will benefit significantly from advances or improvements in technology. These companies generally fall into two categories: (i) companies that portfolio management
86 | Janus Investment Fund

believes have or will develop products, processes, or services that will provide significant technological advancements or improvements; and (ii) companies that portfolio management believes rely extensively on technology in connection with their operations or services. Some of the industries and companies likely to be represented in the fund’s portfolio include e-commerce (companies doing business through the Internet); computer (hardware and software); communications (voice, data, and wireless); industrials; Internet (software, services, and infrastructure equipment); and media and entertainment. The fund implements this policy by investing primarily in equity securities of U.S. and foreign companies selected for their growth potential. The fund typically invests at least 40% of its net assets in securities of issuers or companies that are economically tied to different countries throughout the world, excluding the United States.

The fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield/high-risk securities rated below investment grade. Securities rated below investment grade may include their unrated equivalents or other high-yielding securities portfolio management believes offer attractive risk/return characteristics. The fund may at times invest all of its assets in such securities. The fund may also invest in money market instruments and foreign debt securities. The fund may also invest in floating rate obligations, such as collateralized loan obligations, floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The fund may also invest in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities.
Janus Henderson Mid Cap Value Fund seeks capital appreciation. The fund pursues its investment objective by investing primarily in the common stocks of mid-sized companies and focuses on companies whose stock prices are believed to be undervalued by the fund’s portfolio management or that have fallen out of favor with the market. The fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies whose market capitalization falls, at the time of purchase, within the capitalization range of the Russell Midcap® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $170 million to $78.43 billion. From time to time, the fund may invest in shares of companies through initial public offerings. The fund may also invest in foreign securities, as well as in REITs and similar REIT-like entities.
Janus Henderson Mortgage-Backed Securities ETF seeks a high level of total return consisting of income and capital appreciation. The fund seeks to achieve its investment objective by investing mainly in mortgage-related instruments. Under normal circumstances, the fund will invest at least 80%, and often times substantially all, of its net assets (plus any borrowings for investment purposes) in a portfolio of mortgage-related fixed income instruments of varying maturities. Mortgage-related fixed income instruments include residential and commercial mortgage-backed securities (“MBS”), collateralized mortgage obligations, stripped mortgage-backed securities, mortgage pass-through securities, credit risk transfer securities, and other securities representing an interest in or secured by or related to mortgages, including asset-backed securities and securities issued by other ETFs that invest principally in MBS. Under normal circumstances, the fund will invest predominantly in mortgage-related securities issued by the U.S. government and its agencies, such as the Government National Mortgage Association, the Federal National Mortgage Association or the Federal Home Loan Mortgage Corporation. The fund may also invest up to 20% of its net assets in non-agency, or privately-issued, residential and commercial MBS, and other non-agency or privately issued mortgage-related and asset-backed securities. The fund will typically enter into “to be announced” or “TBA” commitments when purchasing MBS, which allows the fund to agree to pay for certain yet-to-be issued securities at a future date and which may have a leveraging effect on the fund. Similar to its use of leverage with respect to TBAs, the fund may enter into reverse repurchase agreement transactions and use the cash made available from these transactions to make additional investments in mortgage-related instruments or other fixed-income securities. In addition to its investments in mortgage-backed and mortgage-related securities, the fund will from time to time also invest in certain other fixed-income securities and/or hold cash and cash-equivalents (such as U.S. treasuries). The fund will invest primarily in securities rated investment grade (that is, securities rated Baa3/BBB- or higher, or if unrated, determined to be of comparable credit quality by the Adviser). The fund may also invest in lower-rated, higher-yielding securities, including securities rated below investment grade, when the Adviser believes that the increased risk of such lower rated securities is justified by the potential for increased return. The fund invests only in U.S. dollar denominated securities. The fund may
87 | Janus Investment Fund

invest its uninvested cash in affiliated or non-affiliated money market funds or unregistered cash management pooled investment vehicles that operate as money market funds. The fund also invests in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. Additionally, the fund may invest in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, interest rates, or market indices. In particular, the fund may use swaps, futures, forward contracts and options. The fund may use derivatives only to manage or hedge portfolio risk, including interest rate risk, or to manage duration. The fund’s exposure to derivatives will vary. The fund may also enter into short positions for hedging purposes.
Janus Henderson Overseas Fund seeks long-term growth of capital.

The fund may invest up to 20% of its net assets, measured at the time of purchase, in U.S. issuers. The fund may have significant exposure to emerging markets.

Janus Henderson Responsible International Dividend Fund seeks income with the potential for capital growth over the long-term. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-producing equity securities. The fund may invest in common stocks, preferred stocks, depository receipts, and other equity-related securities. The fund’s investment approach (i) seeks to avoid companies and industries that it considers to be involved in business activities and behaviors that may be environmentally and/or socially harmful, and (ii) considers ESG factors and a company’s management of ESG risks. The fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. The fund’s investments may be in non-U.S. currency or U.S. dollar-denominated.
In selecting investments for the fund, portfolio management first seeks to identify equity securities of companies with attractive long-term business prospects that generate profits and produce attractive levels of dividend income. Although the fund does not have a specific policy regarding the growth/value orientation or market capitalization of the companies in which it invests, portfolio management believes that focusing on dividend-producing equity securities will tend to lead to investments in mid-to-large capitalization “value” stocks (stocks of well-established, undervalued companies that portfolio management believes offer the potential for income and long-term capital appreciation). Portfolio management may, however, invest in smaller and less seasoned issuers and in stocks that are considered “growth” stocks. Next, portfolio management applies broad-based negative screens, which incorporate third party inputs, to seek to avoid companies and industries that are directly associated with business activities and behaviors that may be environmentally and/or socially harmful, subject to certain de minimis limits that may be quantitative (e.g., expressed as a company’s revenues) or qualitative in nature.
Janus Henderson Short Duration Flexible Bond Fund seeks as high a level of current income as is consistent with preservation of capital.

The fund will invest at least 65% of its net assets in investment grade debt securities. The fund may invest up to 35% of its net assets in high-yield bonds.

The fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities, and may also invest in inflation-linked securities, including Treasury Inflation-Protected Securities, also known as TIPS. The fund may also invest in securities that have contractual restrictions that prohibit or limit their resale, which may include Rule 144A securities. The fund may also invest in foreign securities. The fund’s average portfolio duration typically ranges between one and three years.
Janus Henderson Short Duration Income ETF seeks to provide a steady income stream with capital preservation across various market cycles. The fund seeks to consistently outperform the FTSE 3-Month US Treasury Bill Index by a moderate amount through various market cycles while at the same time providing low volatility. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets in a portfolio of fixed income instruments of
88 | Janus Investment Fund

varying maturities. As a general indication of the fund’s risk/return profile, portfolio management will seek to select fixed-income instruments that can provide a return of 2-3% (net of fees) above the FTSE 3-Month US Treasury Bill Index. The fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income while at the same time providing low volatility. The fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed income market. The types of fixed income instruments in which the fund may invest include bonds, debt securities, and other similar instruments issued by various U.S. and foreign public- or private-sector entities. The fund may invest up to 20% of its assets in asset-backed securities that are rated investment grade or of similar quality as determined by the Adviser. From time to time, the fund may invest up to 5% of its assets in asset-backed securities that are rated below investment grade, and up to 5% in non-agency mortgage-backed securities, so long as such instruments, together with other asset-backed securities held by the fund, do not exceed 20% of the fund’s net assets. The fund may also invest in cash or cash equivalents such as commercial paper, repurchase agreements and other short-term fixed-income securities. The fund may invest its uninvested cash in affiliated or non-affiliated money market funds. The fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities. Under normal circumstances, the average portfolio duration of the fund generally will be within 0-2 years of the FTSE 3-Month US Treasury Bill Index. The fund normally invests in investment grade debt securities. The fund may invest in high-yield bonds, commercial paper, mortgage-backed securities, and floating rate securities that are rated below investment grade (commonly known as “high-yield debt” or “junk” bonds), but generally intends to invest 15% or less of its net assets in such securities. The fund may invest up to 70% of its assets in foreign securities. The fund may use futures, options and swaps in connection with its principal strategies in certain market conditions for various investment purposes, such as to manage or hedge portfolio risk, enhance return, or manage duration.
Janus Henderson Small Cap Growth Alpha ETF seeks investment results that correspond generally, before fees and expenses, to the performance of its underlying index, the Janus Henderson Small Cap Growth Alpha Index (the “Underlying Index”). The fund pursues its investment objective by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in the securities that comprise the Underlying Index. The Underlying Index is composed of common stocks of small-sized companies that are included in the Solactive Small Cap Index, a universe of 2,000 small-sized capitalization stocks. The Solactive Small Cap Index uses the total public market value, or “free-float,” capitalization of a stock to determine whether to include such stock in the Solactive Small Cap Index. The Underlying Index is designed to select small-sized capitalization stocks that are poised for “smart growth” by evaluating each company’s performance in three critical areas: growth, profitability, and capital efficiency. Using a proprietary quantitative methodology, such stocks are scored based on fundamental measures of their growth, profitability, and capital efficiency, and the top 10% of such eligible stocks scoring the highest become the constituents of the Underlying Index. Market capitalizations within the Underlying Index will vary, but as of October 31, 2023, they ranged from approximately $24 million to $9.02 billion. The fund uses a “passive,” index-based approach in seeking performance that corresponds to the performance of the Underlying Index. The fund generally will use a replication methodology, meaning it will invest in the securities composing the Underlying Index in proportion to the weightings in the Underlying Index. However, the fund may utilize a sampling methodology under various circumstances in which it may not be possible or practicable to purchase all of the securities in the Underlying Index. The fund may also invest in investments that are not included in the Underlying Index. Such investments include stocks, shares of other investment companies, cash and cash equivalents, including affiliated or non-affiliated money market funds (or unregistered cash management pooled investment vehicles that operate as money market funds).
Janus Henderson Small Cap Value Fund seeks capital appreciation. The fund pursues its investment objective by investing primarily in the common stocks of small companies and focuses on companies whose stock prices are believed to be undervalued by the fund’s portfolio management or that have fallen out of favor with the market.

The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $3 million to $13.14 billion. The 12-month average of the maximum market capitalization for companies included in the Russell 2000 Value Index for the one-year period ended June 30, 2024 was $8.48 billion.

89 | Janus Investment Fund

borrowings for investment purposes) in the securities that comprise the Underlying Index. The Underlying Index is designed to select small- and medium-sized capitalization stocks that are poised for “smart growth” by evaluating each company’s performance in three critical areas: growth, profitability, and capital efficiency. A stock may not represent more than 3% of the Underlying Index. The Underlying Index seeks risk adjusted outperformance relative to a market capitalization weighted universe of small- and medium-sized capitalization growth stocks. Market capitalizations within the Underlying Index will vary, but as of October 31, 2023, they ranged from approximately $24 million to $32.22 billion.
Janus Henderson Small-Mid Cap Value Fund seeks capital appreciation.

The market capitalizations within the index will vary but, as of June 30, 2024, they ranged from approximately $3 million to $30.32 billion. The 12-month average of the maximum market capitalization of companies included in the Russell 2500 Value Index for the one-year period ended June 30, 2024 was $23.19 billion.

The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.
The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.
ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).
Letter of Intent (“LOI”)
Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.
If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the underlying funds may invest, as well as some general investment terms. The underlying funds may invest in these instruments to the extent permitted by their investment objectives and policies. The underlying funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. An underlying fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Duration is a measurement of price sensitivity to interest rate changes. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by an underlying fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, an underlying fund’s duration is usually shorter than its average maturity. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter duration. For example, the price of a bond portfolio with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. An underlying fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise.
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
High-yield bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba1 or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”
99 | Janus Investment Fund

Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that an underlying fund must pay if these investments are profitable, the underlying fund may make various elections permitted by the tax laws. These elections could require that an underlying fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Private placements are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Rule 144A securities are securities that are not registered for sale to the general public under the Securities Act of 1933, as amended, but that may be resold to certain institutional investors.
Senior securities are securities that rank above an issuing company’s other securities in the event of a bankruptcy or liquidation, which means an underlying fund would be in line to receive repayment of its investment before certain of the company’s other creditors.
“To be announced” or “TBA” commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining an underlying fund’s net asset value. Because an underlying fund is generally not required to pay for the security until the settlement date, if the underlying fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
100 | Janus Investment Fund

Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
Zero coupon bonds are debt obligations that do not pay regular cash interest payments at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. An underlying fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. An underlying fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Inflation index swaps involve the exchange by an underlying fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments or an exchange of floating rate payments based on two different reference indices). By design, one of the reference indices is an inflation index, such as the Consumer Price Index.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. An underlying fund may purchase and write put and call options on securities, securities indices, and foreign currencies. An underlying fund may purchase or write such options individually or in combination.
Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period. A fixed-income total return swap may be written on many different kinds of underlying reference assets, and may include different indices for various kinds of debt securities (e.g., U.S. investment grade bonds, high-yield bonds, or emerging market bonds).

Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which a Fund’s or an underlying fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Diversification is a classification given to a fund under the Investment Company Act of 1940, as amended. Funds are classified as either diversified or nondiversified. To be classified as diversified under the Investment Company Act of 1940, as amended, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as nondiversified under the Investment Company Act of 1940, as amended, on the other hand, has the flexibility to take larger positions in securities than a fund that is classified as diversified. However, because the appreciation or depreciation of a single security may have a greater impact on the net asset value of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified.
Industry concentration for purposes under the Investment Company Act of 1940, as amended, is the investment of 25% or more of an underlying fund’s total assets in an industry or group of industries.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain underlying funds, while others do not emphasize investments in companies of any particular size.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by an underlying fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the underlying fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Short sales in which an underlying fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that an underlying fund owns, or the underlying fund has the right to obtain the amount of the security sold short at a specified date in the future. An underlying fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the underlying fund loses the opportunity to participate in the gain. For short sales, the underlying fund will incur a loss if the value of a security increases during this period because it will be paying more for the security than it has received from the purchaser in the short sale. If the price declines during this period, an underlying fund will realize a short-term capital gain. Although an underlying fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, its potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. While there is no limit on each Fund’s use of short sales, the Funds do not intend to enter into short positions. This does not preclude the underlying funds from investing in short sales.
When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
1 Year

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing primarily in the common stocks of mid-sized companies and focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies whose market capitalization falls, at the time of purchase, within the capitalization range of the Russell Midcap® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $170 million to $78.43 billion. From time to time, the Fund may invest in shares of companies through initial public offerings.
The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
2 | Janus Henderson Mid Cap Value Fund

strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Mid-Sized Companies Risk.Investments in securities issued by mid-sized companies may involve greater risks than are customarily associated with larger, more established companies. For example, mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by mid-sized companies tend to be more volatile than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
3 | Janus Henderson Mid Cap Value Fund

Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares (formerly named Investor Shares). For periods prior to April 21, 2003, the performance shown for Class D Shares reflects the historical performance of Berger Mid Cap Value Fund – Investor Shares (as a result of a prior reorganization of Berger Mid Cap Value Fund – Investor Shares into the Fund’s former Class J Shares). If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell Midcap Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell Midcap Value Index as a performance benchmark because the Russell Midcap Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell Midcap Value Index measures the performance of those Russell Midcap companies with lower price-to-book ratios and lower forecasted growth values.
After-tax returns are calculated using distributions for the Fund’s Class D Shares for periods following February 16, 2010; for the Fund’s Class J Shares (formerly named Investor Shares) for the period April 21, 2003 to February 16, 2010; and for Berger Mid Cap Value Fund – Investor Shares for periods prior to April 21, 2003. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-producing equity securities. The Fund generally invests in a core group of 40-60 equity securities, including common stocks, preferred stocks, depository receipts, and other equity-related securities. The Fund’s investment approach (i) seeks to avoid companies and industries that it considers to be involved in business activities and behaviors that may be environmentally and/or socially harmful, and (ii) considers environmental, social, and governance (“ESG”) factors and a company’s management of ESG risks.
The Fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the company’s
7 | Janus Henderson Responsible International Dividend Fund

revenues are derived from one or more countries outside of the United States; or (iii) a majority of the company’s assets are located in one or more countries outside of the United States. The Fund’s investments may be in non-U.S. currency or U.S. dollar-denominated.
In selecting investments for the Fund, portfolio management first seeks to identify equity securities of companies with attractive long-term business prospects that generate profits and produce attractive levels of dividend income. Although the Fund does not have a specific policy regarding the growth/value orientation or market capitalization of the companies in which it invests, portfolio management believes that focusing on dividend-producing equity securities will tend to lead to investments in mid-to-large capitalization “value” stocks (stocks of well-established, undervalued companies that portfolio management believes offer the potential for income and long-term capital appreciation). Portfolio management may, however, invest in smaller and less seasoned issuers and in stocks that are considered “growth” stocks.
Next, portfolio management applies broad-based negative screens, which incorporate third party inputs, to seek to avoid companies and industries that are directly associated with business activities and behaviors that may be environmentally and/or socially harmful, subject to certain de minimis limits that may be quantitative (e.g., expressed as a percentage of a company’s revenues) or qualitative in nature. A current list of such business activities and behaviors, which may evolve over time, follows:
Adult entertainment;
Alcohol;
Animal testing for non-medical purposes;
Armaments;
Fossil fuel extraction and refining;
Fossil fuel power generation;
Fur;
Gambling; and
Tobacco
The screening process is also used to exclude companies that are United Nations Global Compact violators and companies that are in breach of the Organization for Economic and Co-operation and Development Guidelines for Multinational Enterprises.
In selecting investments, the Fund also considers ESG factors and a company’s management of ESG risks that may have a significant impact on the company’s growth, valuation, profits, cash flow, and dividends. Such factors may include corporate governance, human capital and diversity, climate change, disclosure transparency, and business ethics. The Fund evaluates ESG factors and risks, using third-party data and internally-generated analysis, which may include assessments of a company’s alignment with international commitments, a review of ESG investment risk reports, and corporate engagement. At portfolio management’s discretion, the Fund will engage with a company’s senior management to seek to better understand improvements in ESG reporting and disclosure, environmental performance, and strategic positioning in relation to key sustainability trends. The Fund may invest in companies whose ESG practices are evolving, with the expectation that these engagement efforts will result in improvements over time, and will consider selling a security if a company is not responsive to such engagement efforts. The Fund does not consider ESG factors and risks in managing the Fund’s exposure to cash and cash equivalents and certain derivatives, such as forward currency contracts used for hedging purposes.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is a risk of significant deterioration in the company’s fundamentals, there is a change in business strategy or issuer-specific business outlook that affects the original investment case, or if a superior investment opportunity arises. The Fund will also consider selling a security if, in portfolio management’s opinion, the company’s business model no longer meets the investment criteria employed in managing the Fund.
The Fund may invest its assets in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests or to hedge portfolio risk. In particular, the Fund may invest in derivatives such as forward currency contracts to offset risks associated with currency exposure.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.

Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The Fund’s investment strategies could result in significant fluctuations of dividend income. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
ESG Investment Risk.As a result of the Fund’s ESG-related strategy, the Fund may perform differently than funds that do not have an ESG-related strategy. Due to the ESG considerations and exclusionary criteria employed by the Fund, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. ESG-related information provided by issuers and third parties, which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to consider their environmental or social practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the issuers identified through the investment process employed by the Fund may fail to adhere to positive environmental or social practices, which may result in selling a security when it might otherwise be disadvantageous to do so.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
Issuer Concentration Risk.The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments.
Geographic Concentration Risk.To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.
Europe Risk.The Fund is subject to certain risks associated with Europe and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent. Changes in regulations on trade, decreasing imports or exports, changes in the exchange rate of European currencies, and recessions among European countries may have a significant adverse effect on the economies of other European countries. Western Europe has, in certain instances, been susceptible to serious financial hardship, high debt levels, and high levels of unemployment. The markets in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments.

Currency Risk.Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Dividend-Oriented Stocks Risk.Companies that have paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the security held by the Fund or the Fund receiving less income.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Depositary Receipts Risk.Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets.
Mid-Sized Companies Risk.Investments in securities issued by mid-sized companies may involve greater risks than are customarily associated with larger, more established companies. For example, mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by mid-sized companies tend to be more volatile than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives
10 | Janus Henderson Responsible International Dividend Fund

entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on June 5, 2017. The performance shown for Class D Shares for periods prior to June 5, 2017, reflects the performance of Class I Shares of Henderson Dividend & Income Builder Fund (the “Predecessor Fund”), calculated using the estimated fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers. The Predecessor Fund was advised by Henderson Global Investors (North America) Inc. and subadvised by Henderson Investment Management Limited. Class A Shares, Class C Shares, Class I Shares, and Class R6 Shares of the Predecessor Fund were reorganized into Class A Shares, Class C Shares, Class I Shares, and Class N Shares, respectively, of the Fund on June 2, 2017. In connection with this reorganization, certain shareholders of the Predecessor Fund who held shares directly with the Predecessor Fund and not through an intermediary had the Class A Shares, Class C Shares, Class I Shares, and Class N Shares of the Fund received in the merger automatically exchanged for Class D Shares of the Fund following the merger. If Class D Shares of the Fund had been available during periods prior to June 5, 2017, the performance shown may have been different because the Fund and the Predecessor Fund have different expenses. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective October 28, 2022, the Fund changed its investment strategy. Performance prior to October 28, 2022 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s (and the Predecessor Fund’s) past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 36% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing primarily in the common stocks of small companies and focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization for companies included in the Russell 2000® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $3 million to $13.14 billion. The 12-month average of the maximum market capitalization for companies included in the Russell 2000 Value Index for the one-year period ended June 30, 2024 was $8.48 billion. From time to time, the Fund may invest in shares of companies through initial public offerings. The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
14 | Janus Henderson Small Cap Value Fund

sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Small-Sized Companies Risk.Investments in securities issued by small-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
15 | Janus Henderson Small Cap Value Fund

Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares (formerly named Investor Shares). If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell 2000 Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell 2000 Value Index as a performance benchmark because the Russell 2000 Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell 2000 Value Index measures the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values.
After-tax returns are calculated using distributions for the Fund’s Class D Shares for periods following February 16, 2010, and for the Fund’s Class J Shares (formerly named Investor Shares) for periods prior to February 16, 2010.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of small- and mid-sized companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization of companies included in the Russell 2500tm Value Index. The market capitalizations within the index will vary but, as of June 30, 2024, they ranged from approximately $3 million to $30.32 billion. The 12-month average of the maximum market capitalization of companies included in the Russell 2500 Value Index for the one-year period ended June 30, 2024 was $23.19 billion. The Fund focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund normally invests in a portfolio of 35-50 equity securities, which consist primarily of
19 | Janus Henderson Small-Mid Cap Value Fund

common stocks, but may also include other types of instruments. From time to time, the Fund may invest in shares of companies through initial public offerings.
The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Small- and Mid-Sized Companies Risk.Investments in securities issued by small- and mid-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Issuer Concentration Risk.The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would
20 | Janus Henderson Small-Mid Cap Value Fund

affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective August 1, 2019, the Fund changed its investment strategy. Performance prior to August 1, 2019 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell 2500 Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell 2500 Value Index as a performance benchmark because the Russell 2500 Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell 2500 Value Index measures the performance of those Russell 2500 companies with lower price-to-book ratios and lower forecasted growth values.

Additional information about the Funds
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services, as well as reimbursement to the Adviser of its out-of-pocket costs for services as administrator. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by each Fund to the Adviser. Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund each pay an investment advisory fee rate that adjusts up or down by a variable rate of up to 0.15% (assuming constant assets) on a monthly basis based upon the Fund’s performance relative to its benchmark index during a measurement period. This base fee rate, prior to any performance adjustment, is 0.64% for Janus Henderson Mid Cap Value Fund, 0.72% for Janus Henderson Small Cap Value Fund, and 0.70% for Janus Henderson Small-Mid Cap Value Fund. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses”

°
include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that a Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. Such amounts are less than 0.01%.
°
may include reimbursement to the Transfer Agent of its out-of-pocket costs for arranging for the provision by third parties of certain servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse each Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus. Because a fee waiver and/or reimbursement will have a positive effect upon a fund’s performance, a fund that pays a performance-based investment advisory fee may experience a performance adjustment that is considered favorable to the Adviser as a result of a fee waiver and/or reimbursement that is in place during the period when the performance adjustment applies.
All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, a Fund will provide shareholders with at least 60 days’ notice prior to changing the
24 | Janus Investment Fund

80% investment policy. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary sections, including the types of securities each Fund may invest in when pursuing its investment objective. This section also describes investment strategies and policies that the Funds may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since a Fund’s composition can change over time. Except for the Funds’ policies with respect to illiquid investments, borrowing, and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
Portfolio management for Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund primarily invests in the common stocks of companies and focuses on companies whose stock prices are believed to be undervalued or that have fallen out of favor with the market. Portfolio management looks for companies with strong fundamentals and competent management.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation. Portfolio management will generally consider selling a Fund holding if, among other things, the security reaches portfolio management’s price target, if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks, or if portfolio management finds a better investment opportunity. Portfolio management will also consider selling a Fund holding to meet redemptions.
A company may be considered attractively valued when, in the opinion of portfolio management, shares of the company are selling for a price that is below their intrinsic worth (“undervalued”). A company may be undervalued due to market or economic conditions, temporary earnings declines, unfavorable developments affecting the company, or other factors. Such factors may provide buying opportunities at attractive prices compared to historical or market price-earnings ratios, price/free cash flow, book value, or return on equity. Portfolio management believes that buying these securities at a price that is below their intrinsic worth may generate greater returns for a Fund than those obtained by paying premium prices for companies currently in favor in the market.
Janus Henderson Responsible International Dividend Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-producing equity securities. The Fund’s investment approach (i) seeks to avoid companies and industries that it considers to be involved in business activities and behaviors that may be environmentally and/or socially harmful, and (ii) considers environmental, social, and governance (“ESG”) factors and a company’s management of ESG risks. The Fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. The Fund’s investments may be in non-U.S. currency or U.S. dollar-denominated. In pursuing its investment objective, portfolio management first seeks to identify equity securities of companies with attractive long-term business prospects that generate profits and produce attractive levels of dividend income. Although the Fund does not have a specific policy regarding the growth/value orientation or market capitalization of the companies in which it invests, portfolio management believes that focusing on dividend-producing equity securities will tend to lead to investments in mid-to-large capitalization “value” stocks (stocks of well-established, undervalued companies that portfolio management believes offer the
25 | Janus Investment Fund

potential for income and long-term capital appreciation). Portfolio management may, however, invest in smaller and less seasoned issuers and in stocks that are considered “growth” stocks.
Next, portfolio management applies broad-based negative screens, which incorporate third-party inputs, to seek to avoid companies and industries that are directly associated with business activities and behaviors that may be environmentally and/or socially harmful, subject to certain de minimis limits that may be quantitative (e.g., expressed as a percentage of a company’s revenues) or qualitative in nature. When an activity relates to a company’s revenues, a 10% threshold is applied. The qualitative assessment looks at the extent to which an “avoided” activity is part of a company’s business and whether a company is taking action to address and improve upon such activity. A current list of such business activities and behaviors, which may evolve over time, follows:
Adult entertainment;
Alcohol;
Animal testing for non-medical purposes;
Armaments;
Fossil fuel extraction and refining;
Fossil fuel power generation;
Fur;
Gambling; and
Tobacco.
The screening process is also used to exclude companies that are United Nations Global Compact violators and companies that are in breach of the Organization for Economic and Co-operation and Development Guidelines for Multinational Enterprises.
Portfolio management considers inputs from third-party data providers in implementing the Fund’s investment strategies. The third-party data providers used by portfolio management are disclosed in the Fund’s SAI and are subject to change over time.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is a risk of significant deterioration in the company’s fundamentals, there is a change in business strategy or issuer-specific business outlook that affects the original investment case, or if a superior investment opportunity arises. The Fund will also consider selling a security if, in portfolio management’s opinion, the company’s business model no longer meets the investment criteria employed in managing the Fund.
Cash Position
The Funds may not always stay fully invested. For example, when portfolio management believes that market conditions are unfavorable for investing, or when it is otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. Due to differing investment strategies, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Derivatives
A Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. A Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
26 | Janus Investment Fund

Emerging Markets
Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Indexsm.
ESG Integration
As part of a Fund’s investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors may include corporate governance, political governance, executive pay, board structure and diversity, business ethics, corporate reporting, company culture, human capital management and diversity, community relations, human rights, exposure to climate change, biodiversity, and deforestation. Portfolio management focuses on the ESG Factors it considers most likely to have a material impact on the long-term financial performance of the issuer, which includes identifying ESG Factors attributable to a particular region, sector, industry, or issuer. To facilitate its assessment of ESG Factors, portfolio management uses issuer reports, third-party data and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio. Portfolio management may assess the relevance of ESG Factors to its fundamental research process differently across issuers, sectors, regions, and asset classes.
Exchange-Traded Funds
Certain Funds may invest in exchange-traded funds (“ETFs”) to gain exposure to a particular portion of the market. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of a Fund, which will be indirectly paid by such Fund. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. A Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
Each Fund may invest in foreign securities. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. The Funds may at times have significant foreign exposure, including exposure to emerging markets.
Illiquid Investments
A Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
Initial Public Offerings and Secondary Offerings
Certain Funds may purchase shares issued as part of, or a short period after, a company’s initial public offering (“IPO”), and may at times dispose of those shares shortly after their acquisition. An IPO is the first sale of stock by a private company to the public. IPOs are often issued by smaller, younger companies seeking the capital to expand, but can also be done by large privately-owned companies looking to become publicly traded. Certain Funds may also purchase shares in offerings made by companies that are publicly traded (“secondary offerings”). Secondary offerings may be made by companies for a number of reasons, including as part of a refinancing, to raise capital for growth, and/or to provide existing shareholders with a way to register and sell restricted shares.
Leverage
Certain of a Fund’s investments, including derivatives and short sale transactions, involve the use of leverage. Leverage is investment exposure which exceeds the initial amount invested. Leverage occurs when a Fund increases its assets available for investment using derivatives, short sales, when-issued, delayed delivery, or forward commitment transactions, or other similar transactions. The use of other investment techniques can also create a leveraging effect on a Fund.
27 | Janus Investment Fund

Portfolio Turnover
In general, each Fund intends to purchase securities for long-term investment, although, to a limited extent, a Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to shareholder purchases and redemptions), the nature of a Fund’s investments, and the investment style of portfolio management. Changes are normally made in a Fund’s portfolio whenever portfolio management believes such changes are desirable. Portfolio turnover rates are generally not a factor in making buy and sell decisions for the Funds.
Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in the acceleration of taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
REITs and Real Estate-Related Securities
Each Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Securities Lending
A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. A Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, a Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and a Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If a Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to a Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.

Short Sales
A Fund may invest in short positions through short sales of stocks and structured products, and through derivatives that include swaps, uncovered written calls, and futures. A Fund may also engage in short sales “against the box” and options for hedging purposes. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility.
A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the borrowed securities be returned to the lender on short notice, and the Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, a “short squeeze” can occur, which means that the demand is greater than the supply for the stock sold short. If a short squeeze occurs, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a fund that does not engage in short sales and may negatively affect the Fund’s performance.
A Fund may enter into a derivatives transaction to obtain short investment exposure to an underlying reference asset. If the value of the underlying reference asset on which a Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes a Fund to credit risk, counterparty risk, and leverage risk.
Special Situations
The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of portfolio management, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.
Other Types of Investments
Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:
debt securities (such as bonds, notes, and debentures)
preferred stocks and securities convertible into common stocks or preferred stocks
29 | Janus Investment Fund

indexed/structured securities (such as commercial and residential mortgage- and asset-backed securities)
pass-through securities including commercial and residential mortgage- and asset-backed securities and mortgage dollar rolls
securities purchased on a when-issued, delayed delivery, or forward commitment basis
equity and fixed-income securities issued in private placement transactions
Risks of the Funds
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. To varying degrees, the Funds may invest in stocks, fixed-income securities, money market instruments or cash/cash equivalents, and derivatives. The following information is intended to help you better understand some of the risks of investing in the Funds, including those risks that are summarized in the Fund Summary sections. This information also includes descriptions of other risks a Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, a Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of swaps, futures, and options). Each Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause a Fund to be more volatile than if it had not used leverage.
The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk. There is no guarantee that portfolio management’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.
Forward Foreign Currency Exchange Contract Risk.Forward foreign currency exchange contracts (“forward currency contracts”) involve the risk that unanticipated changes in currency prices may negatively impact a Fund’s performance. Moreover, there may be an imperfect correlation between a Fund’s portfolio holdings of securities quoted or denominated in a particular currency and any forward currency contracts entered into by the Fund, which will expose the Fund to risk of
30 | Janus Investment Fund

foreign exchange loss. The trading markets for forward currency contracts offer less protection against defaults than trading in currency instruments on an exchange. Because a forward currency contract is not guaranteed by an exchange or clearinghouse, a default on the contract could result in losses to a Fund and may force the Fund to cover its purchase or sale commitments, if any, at the current market price. In addition, forward currency contract markets can experience periods of illiquidity, which could prevent a Fund from divesting of a forward currency contract at the optimal time and may adversely affect a Fund’s returns and net asset value.
Emerging Markets Risk.Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
ESG Integration and Investment Risk.There is a risk that considering ESG Factors as part of a Fund’s investment process may fail to produce the intended results or that a Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require a Fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
Janus Henderson Responsible International Dividend Fund has an ESG-related strategy and may employ exclusionary criteria to avoid investing in certain industries, activities, or assets considered by portfolio management to have a negative impact on society or the environment. This Fund is subject to similar risks as those Funds that consider ESG Factors as part of their investment process.
European Investments Risk.Exposure to investments in European countries may expose a Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. A Fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which
31 | Janus Investment Fund

may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.
Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When a Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, a Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which a Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, a Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because a Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.
Foreign Exposure Risk.Within the parameters of its specific investment policies, each Fund may invest in foreign equity and debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:
Currency Risk.As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Foreign Market Risk.Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.
Geographic Concentration Risk.To the extent that a Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified
32 | Janus Investment Fund

fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.
Political and Economic Risk.Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the U.S. Government on other countries or persons or issuers operating in such countries could restrict a Fund’s ability to buy affected securities or force a Fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, a Fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
Regulatory Risk.There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
Transaction Costs.Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
Industry and Sector Risk.Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase that Fund’s exposure to industry and sector risk.
Initial Public Offering and Secondary Offering Risk.A Fund’s purchase of shares issued in an IPO exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. Attractive IPOs are often oversubscribed and may not be available to the Funds, or may be available only in very limited quantities. The market for IPO issuers has been volatile, and share prices of newly public companies have fluctuated up and down significantly over short periods of time. There can be no assurance that the Funds will identify favorable IPO investment opportunities. In addition, under certain market conditions, a relatively small number of companies may issue securities in IPOs. Similarly, as the number of Funds to which IPO securities are allocated increases, the number of securities issued to any one Fund may decrease. In addition, as a fund increases in size, the impact of IPOs on the fund’s performance will generally decrease.
A Fund may purchase shares in secondary offerings. Secondary offerings may expose a Fund to some of the risks of IPOs. Participation in secondary offerings may have a magnified impact on the performance of a fund to the extent that it has a small asset base and the fund may not experience similar performance as its assets grow. Secondary offering shares frequently are volatile in price. As a result, a Fund may hold secondary offering shares for a very short period of time. This may increase the portfolio turnover rate of the Fund and may lead to increased expenses for the Fund, such as commissions and transaction costs. In addition, secondary offering shares can experience an immediate drop in value if the demand for the securities does not continue to support the offering price.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of a Fund’s shares. A Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller
33 | Janus Investment Fund

asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares.
Leverage Risk.Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose a Fund to greater risk and increase its costs. The use of leverage may cause a Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act of 1940, as amended, and the rules thereunder. Increases and decreases in the value of a Fund’s portfolio will be magnified when the Fund uses leverage.
Liquidity Risk.A Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, a Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, a Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect a Fund’s value or prevent such Fund from being able to take advantage of other investment opportunities.
Liquidity risk may also refer to the risk that a Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of portfolio securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s net asset value, may increase brokerage costs, and may result in taxable capital gains.
Market Risk.The value of a Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Portfolio Management Risk.The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and research process employed for the Funds may fail to produce the intended results. Accordingly, the Funds may underperform benchmark indices or other funds with similar investment objectives.
REIT and Real Estate-Related Securities Risk.To the extent a Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the
34 | Janus Investment Fund

quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which a Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. A Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing the return to the Fund on its investment in such company.
Small- and Mid-Sized Companies Risk.A Fund’s investments in securities issued by small- and mid-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on a Fund’s returns, especially as market conditions change.

Management of the Funds
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. The Adviser is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning the Funds’ investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of each Fund. In addition, the Adviser utilizes a personnel-sharing arrangement with its foreign (non-U.S.) affiliate, Janus Henderson Investors UK Limited (“JHIUKL”), pursuant to which one or more Janus Henderson employees, acting for JHIUKL, may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for JHIUKL, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to Janus Henderson Responsible International Dividend Fund on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the Securities and Exchange Commission (the “SEC”) that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of a Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate a Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that a Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to a Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for a Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Funds, including providing office space for the Funds and providing personnel to serve as officers to the Funds. The Funds reimburse the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Funds’ Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Funds. The Funds pay these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Funds.
Management expenses
Each Fund pays the Adviser an investment advisory fee and incurs expenses, including administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay.
The following tables reflect each Fund’s contractual investment advisory fee rate or base fee rate, as applicable (expressed as an annual rate), as well as the actual compensation rate paid by each Fund to the Adviser after any applicable fee waivers and/or expense reimbursements.

Performance-Based Investment Advisory Fee
As reflected in the table below, Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund each pay an investment advisory fee rate that may adjust up or down based on each Fund’s performance relative to the cumulative investment record of its performance fee benchmark index (referred to in this section as the “benchmark index”) over a rolling 36-month performance measurement period. The second column in the table below shows each Fund’s base fee rate. The third column shows the full performance rate for outperformance or underperformance during the measurement period relative to each Fund’s respective benchmark index. The fourth column shows the performance adjusted investment advisory fee rate, which is equal to each Fund’s base fee rate plus or minus the performance adjustment over the period without any fee waivers. The fifth column shows the actual compensation rate paid by each Fund after any applicable fee waivers and/or expense reimbursements as of the end of the fiscal year.
As an example, if a Fund outperformed its benchmark index over the performance measurement period by its full performance rate (listed in the table below), the advisory fee would increase by 0.15% (assuming constant assets). Conversely, if a Fund underperformed its benchmark index over the performance measurement period by its full performance rate (listed in the table below), the advisory fee would decrease by 0.15% (assuming constant assets). Actual performance within the full range of the full performance rate may result in positive or negative incremental adjustments to the advisory fee of greater or less than 0.15%. Additional details discussing the performance fee are included below with further description in the SAI.

Due to the restatement of the Fund’s investment advisory fee, the investment advisory fee rates stated above will differ from those in the Fund’s expense table earlier in the Prospectus.
For Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund, the investment advisory fee rate is determined by calculating a base fee (shown in the previous table) and applying a performance adjustment (described in further detail below). The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index as shown below:
Fund Name
Benchmark Index
Janus Henderson Mid Cap Value Fund
Russell Midcap Value Index
Janus Henderson Small Cap Value Fund
Russell 2000 Value Index
Janus Henderson Small-Mid Cap Value Fund
Russell 2500 Value Index
The calculation of the performance adjustment applies as follows:
Investment Advisory Fee = Base Fee Rate +/– Performance Adjustment
37 | Janus Investment Fund

The investment advisory fee rate paid to the Adviser by each Fund in the table above consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets based on the Fund’s relative performance compared to the cumulative investment record of its benchmark index over a 36-month rolling performance measurement period.
No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase the Adviser’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease the Adviser’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment advisory fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, the Adviser would reimburse the applicable Fund.
The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to the Adviser may, under some circumstances, exceed the cumulative dollar amount of management fees waived by the Adviser.
The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. After the Adviser determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares against the cumulative investment record of that Fund’s benchmark index, the Adviser applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to the Adviser since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.
A discussion regarding the basis for the Trustees’ approval of the Funds’ investment advisory agreements is included in each Fund’s semiannual report (for the period ended December 31, 2023) and in the Funds’ financial statements (for the period ended June 30, 2024, and moving forward). You can request the Funds’ semiannual reports or financial statements (as they become available), free of charge, by contacting a Janus Henderson representative at 1-800-525-3713. This information is also available, free of charge, at janushenderson.com/reports.
Expense Limitations
The Adviser has contractually agreed to waive the advisory fee payable by each Fund and/or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding any performance adjustments to management fees, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below. The Adviser has agreed to continue each waiver for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the
38 | Janus Investment Fund

discretion of the Board of Trustees. For information about how the expense limit affects the total expenses of each Fund, if applicable, see the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus.

Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that a Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to that Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.

Other information
CLOSED FUND POLICIES
A Fund may limit sales of its Shares to new investors. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Funds
The Funds are distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Funds, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within a single Fund.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well.
How Distributions Affect a Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus Henderson representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
Distribution Options
When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janushenderson.com/individual, by calling a Janus Henderson representative, or by writing to the Funds at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Funds offer the following options:
Reinvestment Option.You may reinvest your income dividends and capital gains distributions in additional shares.
Cash Option.You may receive your income dividends and capital gains distributions in cash.
Reinvest and Cash Option.You may receive either your income dividends or capital gains distributions in cash and reinvest the other in additional shares.
Redirect Option.You may direct your dividends or capital gains distributions to purchase shares of another Janus Henderson fund.
The Funds reserve the right to reinvest uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Shareholder Services and Account Policies.”

TAXES
As with any investment, you should consider the tax consequences of investing in the Funds. The following is a general discussion of certain federal income tax consequences of investing in the Funds. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of a Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, a Fund that invests in REITs is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of a Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Funds may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), a Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds
43 | Janus Investment Fund

from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, the Janus Henderson funds will report cost basis information to you and to the IRS. Each Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If a Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in partnerships, it may be subject to state tax liabilities.

All states have repealed UGMA statutes, enacting UTMA statutes in their place. Existing UGMA accounts established before the date of repeal are grandfathered using the original UGMA age of termination.
Minimum Investment Requirements
Due to the proportionately higher costs of maintaining small accounts, the Funds reserve the right to deduct an annual $25 minimum balance fee per Fund account (paid to the Transfer Agent) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You will receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.
Available Incentive Programs
Bonus Program for Taxable Account Purchases and Tax-Advantaged Account Transfers/Rollovers
Through the Transfer Agent’s Bonus Program, the Transfer Agent will pay a bonus of up to $2,500 to you for making certain eligible purchases of Fund shares in taxable accounts or transfers/rollovers from a non-Janus Henderson fund account into a Janus Henderson fund tax-advantaged account. The Bonus Program is valid with an eligible purchase or transfer/rollover of $20,000 or more. If you meet the eligibility requirements for the Bonus Program and enroll in it, the Transfer Agent will deposit a bonus payment into your Fund account within approximately 30 days after the deposit of eligible funds in good order and receipt of a signed contract governing the Bonus Program. An investor must keep the eligible purchase in the account for a period of 360 calendar days in order to retain the bonus payment. Any sale of the qualifying purchase amount (in whole or in part), transfer, or closure of the account within the 360 calendar day period may result in forfeiture of the bonus payment. Any decline in an account’s value due solely to market value fluctuations will not result in the forfeiture of the bonus payment. Only taxable account purchases or transfers/rollovers to tax-advantaged accounts that are made on or after January 1, 2024 through December 31, 2024 are eligible for a bonus payment. The eligible period for the Bonus Program may be extended beyond this time frame at the sole discretion of the Transfer Agent. Before enrolling in the Bonus Program, consult with your tax advisor about the appropriate tax treatment for the bonus offer and any tax implications associated with the receipt of a bonus payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke this Bonus Program at any time without advance notice.
You can request more information about the Transfer Agent’s Bonus Program and eligibility requirements for taxable accounts by contacting a Janus Henderson representative at 1-800-525-3713 or by visiting www.janushenderson.com/bonus. You can request more information about the Bonus Program for tax-advantaged account transfers/rollovers by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Contribution Match Payments
Investors that transfer/rollover assets from a non-Janus Henderson fund account into a tax-advantaged account are also eligible for the Transfer Agent’s Contribution Match Program. To receive a Transfer Agent’s Contribution Match payment, (i) the value of your tax-advantaged account must remain equal to or greater than the value of the eligible transfer/rollover (but not including any losses due solely to market value fluctuations) for 12 months following the receipt of your transfer/rollover in good order and receipt of a signed contract governing the Contribution Match Program, and (ii) you must provide instructions to the Transfer Agent on how to invest these payments. The Transfer Agent’s Contribution Match payments will commence at the end of the first quarter in 2025 following an eligible contribution during the first quarter of 2025 into a Janus Henderson fund tax-advantaged account. The eligible period for the Transfer Agent’s Contribution Match payments may be extended beyond this time frame at the sole discretion of the Transfer Agent. The Transfer Agent will match a percentage of these contributions based on the aggregate value of eligible 2024 rollover or asset transfer amounts, and provide a matching contribution in an amount up to ten percent of your contribution. Before enrolling in the Contribution Match Program, consult with your tax advisor about the appropriate tax treatment for the Transfer Agent’s Contribution Match payments and any tax implications associated with the receipt of a Contribution Match payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Contribution Match Program at any time without advance notice.

Ready. Invest. Go. Program
New investors creating a new Janus Henderson direct account are eligible to participate in the Transfer Agent’s Ready. Invest. Go. Program. After the new investor has completed the required Ready. Invest. Go. Program Contract, the Transfer Agent will fund the $100 initial investment required for new investors, provided that new investors enroll in Janus Henderson’s automatic investment program in an amount equal to at least $50 per month. New investors will forfeit the $100 bonus contributed by the Transfer Agent if their account is closed or if their automatic monthly investment program payment is terminated within two years from the date the initial investment was made. Investor-initiated amounts outside of the initial investment are redeemable at any time at net asset value. Before enrolling in the Ready. Invest. Go. Program, new investors should consult with their tax advisor about the appropriate tax treatment for participating in the Ready. Invest. Go. Program and any tax implications associated with the receipt of the $100 initial investment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Ready. Invest. Go. Program at any time without advance notice.

Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. A Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which a Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by a Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.
All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after a request is received in good order by a Fund or its agents.
49 | Janus Investment Fund

Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of a Fund’s portfolio securities and the reflection of such change in a Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of a Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by a Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used. Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.

Policies in Relation to Transactions
All requests, including but not limited to, exchanges between a Fund and other Janus Henderson funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus Henderson’s P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase.
Administrative services fees
The Funds pay an annual administrative services fee based on the average daily net assets of Class D Shares, as detailed below.
Average Daily Net Assets of Class D Shares of the Janus Henderson funds
Administrative Services Fee
Under $40 billion
0.12%
$40 billion - $49.9 billion
0.10%
Over $49.9 billion
0.08%
These administrative services fees are paid by Class D Shares of each Fund. The Transfer Agent provides or arranges for the provision of shareholder services including, but not limited to, recordkeeping, accounting, answering inquiries regarding accounts, transaction processing, transaction confirmations, and the mailing of prospectuses and shareholder reports.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary and when considering which share class of a fund is most appropriate.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or
51 | Janus Investment Fund

recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you.
Paying for shares
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to buy shares.
Please note the following when purchasing Shares:
Cash, credit cards, third party checks (with certain limited exceptions), travelers cheques, credit card checks, line of credit checks, or money orders will not be accepted.
All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted non-U.S. bank.
Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.
When purchasing Shares through the Automatic Investment Program, your automatic investment selection(s) will generally be active within three days following receipt of your authorization for the date and amount you specify. If no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. If the balance in the Janus Henderson fund account you are buying into falls to zero as the result of a redemption, exchange, or minimum balance fee, your Automatic Investment Program will be discontinued.
We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Funds by submitting good funds via another method accepted by the Funds (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.
Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”
If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as applicable, will be invested in Janus Henderson Government Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus Henderson to (i) buy shares of another Janus Henderson fund or (ii) sell shares of Janus Henderson Government Money Market Fund and return the proceeds (including any dividends earned) to you, Janus Henderson will treat your inaction as approval of the purchase of Janus Henderson Government Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus Henderson for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Henderson Government Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Henderson Government Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will be automatically exchanged from Janus Henderson Government Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”
52 | Janus Investment Fund

For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.
If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and any losses incurred by a Fund as a result. A Fund may redeem shares held in your account to cover any losses it incurs if your purchase is cancelled.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), the Adviser is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, the Adviser may temporarily limit additional share purchases. In addition, the Adviser may close an account if it is unable to verify a shareholder’s identity. Please contact a Janus Henderson representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
The Funds have also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Funds are required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.
Exchanges
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Please note the following when exchanging Shares:
An exchange represents the redemption (or sale) of shares from one Fund and the purchase of shares of another Fund, which may produce a taxable gain or loss in a non-retirement account.
You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. A Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.
New regular Janus Henderson fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus Henderson fund account you are exchanging from is less than $2,500 ($100 for new regular Fund accounts with an automatic investment program of $50 per month). (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus Henderson fund account you are exchanging from is less than the stated minimum, you must exchange the entire
53 | Janus Investment Fund

balance. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
New Janus Henderson fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
Exchanges between existing Janus Henderson fund accounts must meet the $50 subsequent investment requirement.
For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus Henderson fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. Different restrictions may apply if you invest through an intermediary.
Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
With certain exceptions, exchanges between Janus Henderson fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus Henderson fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.
Note: For the fastest and easiest way to exchange shares, log on to janushenderson.com/individual* 24 hours a day, 7 days a week.

Payment of redemption proceeds
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Funds.
By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.
Next Day Wire Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.
ACH (Automated Clearing House) Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on or about the next bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.
By Check – Redemption proceeds will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.
By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus Henderson fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.
The Funds typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
54 | Janus Investment Fund

Generally, orders to sell Shares may be initiated at any time at janushenderson.com/individual, by telephone, or in writing. Certain accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Funds can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide alternate instructions, your proceeds will be invested in Shares of Janus Henderson Government Money Market Fund during the 15-day hold period.
Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. A temporary hold may also be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult has occurred, is occurring, has been attempted, or will be attempted, as described under “Temporary Suspension of Services.”
Note: For the fastest and easiest way to redeem shares, log on to janushenderson.com/individual* 24 hours a day, 7 days a week.

Large Shareholder Redemptions
Certain large shareholders, such as other funds, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these large shareholders of their holdings in a Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect a Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If a Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.

Written Instructions
To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus Henderson.” Requests or documents received in a language other than English may be inadvertently delayed or returned due to an inability to accurately translate the intended instructions. Please include the following information:
the name of the Janus Henderson fund(s) being redeemed or exchanged;
the account number(s);
the amount of money or number of shares being redeemed or exchanged;
the name(s) on the account;
the signature(s) of one or more registered account owners; and
your daytime telephone number.
Signature Guarantee
A signature guarantee for each registered account owner is required if any of the following is applicable:
You request a redemption by check above a certain dollar amount.
You would like a check made payable to anyone other than the shareholder(s) of record.
You would like a check mailed to an address that has been changed within 10 days of the redemption request.
You would like a check mailed to an address other than the address of record.

A signature guarantee may be refused if any of the following is applicable:
It does not appear valid or in good form.
The transaction amount exceeds the surety bond limit of the signature guarantee.
The guarantee stamp has been reported as stolen, missing, or counterfeit.
How to Obtain a Signature Guarantee
A signature guarantee assures that a signature is genuine. The signature guarantee protects shareholders from unauthorized account transfers. The following financial institutions may guarantee signatures: banks, savings and loan associations, trust companies, credit unions, broker-dealers, and member firms of a national securities exchange. Call your financial institution to see if it has the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Funds are intended for long-term investment purposes, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies and procedures may be cancelled or rescinded by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Funds are also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Funds monitor for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds at all times reserve the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges
56 | Janus Investment Fund

for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund.
The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.
In an attempt to deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Funds’ excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Funds by a collective investment trust managed by the Adviser; (iv) transactions in the Funds by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.
Excessive Trading Risks
Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of a Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by a Fund despite the Funds’ adoption of policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Funds to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.

Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of each Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for each Fund at janushenderson.com/reports. A complete schedule of each Fund’s portfolio holdings is also available in the annual and semiannual financial statements located in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. Each Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation) and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom equity securities ranked by performance attribution, including the percentage attribution to Fund performance, average Fund weighting, and other relevant data points, may be provided monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Funds’ Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.
Shareholder services and account policies
Address Changes
For the easiest way to change the address on your account, visit janushenderson.com/individual. You may also call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Include the name of the Janus Henderson fund(s) you hold, the account number(s), the name(s) on the account, and both the old and new addresses. Certain options may be suspended for 10 days following an address change unless a signature guarantee is provided.
Bank Account Changes
For the easiest way to change your bank account of record or add new bank account information to your account, visit janushenderson.com/individual. You may also send a written request signed by the shareholder of record or by each shareholder of record if more than one. Certain accounts may require a written notice and, in some instances, bank privileges may not be available. If multiple account owners are named on the added bank account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.
You may revoke the authorization to use your bank account information at any time by visiting janushenderson.com/individual, or by sending a written request by mail (Janus Henderson, P.O. Box 219109, Kansas City, MO 64121-9109), or by telephone at 1-800-525-3713. Your request will be processed within a reasonable amount of time upon its receipt.
Distributions
Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janushenderson.com/individual, call a Janus Henderson representative, or send a written request signed by one or more shareholder(s) of record.
Your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.
58 | Janus Investment Fund

Involuntary Redemptions
The Funds reserve the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Funds. This includes, but is not limited to, accounts that a Fund or its agents believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.
Lost (Unclaimed/Abandoned) Accounts
It is important that the Funds maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Funds as undeliverable. Based upon statutory requirements for returned mail, the Adviser will attempt to locate the shareholder or rightful owner of the account. If the Adviser is unable to locate the shareholder, then the Adviser is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
Online and Telephone Transactions
You may initiate many transactions through janushenderson.com/individual or by calling Janus Henderson XpressLine. You may also contact a Janus Henderson representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please call a Janus Henderson representative. The Funds and their agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.
Your ability to access your account or transact business electronically may be impacted due to unexpected circumstances, such as system outages, or during periods of increased web activity. For example, periods of substantial market change or other unexpected events can contribute to high call volumes, which may delay your ability to reach a Janus Henderson representative by telephone.
If you experience difficulty transacting business with us through a particular method, please consider using an alternate method, such as visiting janushenderson.com/individual, calling Janus Henderson XpressLine, contacting a Janus Henderson representative by telephone, or sending written instructions to complete your transaction. Please remember that purchase, exchange, or redemption requests must be received in good order by a Fund or its agents prior to the close of the trading session of the NYSE in order to receive that day’s NAV.
Your account information, including online credentials, should be kept private, and you should immediately review any account statements that you receive from Janus Henderson. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus Henderson immediately about any transactions you believe to be unauthorized.
Registration Changes
To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janushenderson.com/individual or call a Janus Henderson representative for further instructions.
Statements, Reports, and Prospectuses
We will send you a confirmation upon the completion of individual account transactions. We will also send you quarterly account statements detailing financial transactions on open accounts processed year-to-date. Systematic transactions are confirmed on quarterly statements unless otherwise requested. Confirmations and quarterly account statements will be sent to the account address of record unless you have elected to receive online statements. The Funds reserve the right to charge a fee for additional account statement requests.
At account setup, or any time thereafter, you may elect (at janushenderson.com/edelivery) to discontinue physical delivery of quarterly account statements and/or confirmations, and instead receive an e-mail notification when they are available online. All statements are available online regardless of your delivery option elections (to view, you must first establish online access at janushenderson.com/individual).
59 | Janus Investment Fund

The Funds produce shareholder reports semiannually, and update their prospectus annually. You may elect to receive shareholder reports and prospectus updates electronically at janushenderson.com/edelivery. The Funds’ fiscal year ends June 30.
Unless you instruct Janus Henderson otherwise by contacting a Janus Henderson representative, the Funds will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Funds receive your instructions.
Taxpayer Identification Number
On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Funds to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Funds for any penalty that the IRS may impose.
Temporary Suspension of Services
The Funds or their agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Funds may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Funds to redeem their Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.
In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (i) a natural person age 65 and older, or (ii) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests. We may not be aware of factors suggesting financial exploitation of a Specified Adult and may not be able to identify Specified Adults in all circumstances. Furthermore, we are not required to delay the disbursement of redemption proceeds and do not assume any obligation to do so.

Financial highlights
The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if applicable. The information for the Funds for the fiscal periods ended June 30 has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in each Fund’s Form N-CSR and is incorporated by reference into the SAI.
The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in Class D Shares of the Funds (assuming reinvestment of all dividends and distributions).

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
65 | Janus Investment Fund

Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form.
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.

Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year period reflects the conversion to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing primarily in the common stocks of mid-sized companies and focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies whose market capitalization falls, at the time of purchase, within the capitalization range of the Russell Midcap® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $170 million to $78.43 billion. From time to time, the Fund may invest in shares of companies through initial public offerings.
The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
3 | Janus Henderson Mid Cap Value Fund

Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Mid-Sized Companies Risk.Investments in securities issued by mid-sized companies may involve greater risks than are customarily associated with larger, more established companies. For example, mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by mid-sized companies tend to be more volatile than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.

If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, or Class N Shares of the Fund had been available during periods prior to May 31, 2012, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell Midcap Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell Midcap Value Index as a performance benchmark because the Russell Midcap Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell Midcap Value Index measures the performance of those Russell Midcap companies with lower price-to-book ratios and lower forecasted growth values.
After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares) for periods following April 21, 2003; and for Berger Mid Cap Value Fund – Investor Shares for periods prior to April 21, 2003. If Class T Shares of the Fund had been available during periods prior to April 21, 2003, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class R Shares, or Class T Shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.84% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-producing equity securities. The Fund generally invests in a core group of 40-60 equity securities, including common stocks, preferred stocks, depository receipts, and other equity-related securities. The Fund’s investment approach (i) seeks to avoid companies and industries that it considers to be involved in business activities and behaviors that may be environmentally and/or socially harmful, and (ii) considers environmental, social, and governance (“ESG”) factors and a company’s management of ESG risks.
The Fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. A security is deemed to be economically tied to a country or countries outside of the United States if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the company’s revenues are derived from one or more countries outside of the United States; or (iii) a majority of the company’s assets are located in one or more countries outside of the United States. The Fund’s investments may be in non-U.S. currency or U.S. dollar-denominated.
In selecting investments for the Fund, portfolio management first seeks to identify equity securities of companies with attractive long-term business prospects that generate profits and produce attractive levels of dividend income. Although the Fund does not have a specific policy regarding the growth/value orientation or market capitalization of the companies in which it invests, portfolio management believes that focusing on dividend-producing equity securities will tend to lead to investments in mid-to-large capitalization “value” stocks (stocks of well-established, undervalued companies that portfolio management believes offer the potential for income and long-term capital appreciation). Portfolio management may, however, invest in smaller and less seasoned issuers and in stocks that are considered “growth” stocks.
Next, portfolio management applies broad-based negative screens, which incorporate third party inputs, to seek to avoid companies and industries that are directly associated with business activities and behaviors that may be environmentally and/or socially harmful, subject to certain de minimis limits that may be quantitative (e.g., expressed as a percentage of a
10 | Janus Henderson Responsible International Dividend Fund

company’s revenues) or qualitative in nature. A current list of such business activities and behaviors, which may evolve over time, follows:
Adult entertainment;
Alcohol;
Animal testing for non-medical purposes;
Armaments;
Fossil fuel extraction and refining;
Fossil fuel power generation;
Fur;
Gambling; and
Tobacco
The screening process is also used to exclude companies that are United Nations Global Compact violators and companies that are in breach of the Organization for Economic and Co-operation and Development Guidelines for Multinational Enterprises.
In selecting investments, the Fund also considers ESG factors and a company’s management of ESG risks that may have a significant impact on the company’s growth, valuation, profits, cash flow, and dividends. Such factors may include corporate governance, human capital and diversity, climate change, disclosure transparency, and business ethics. The Fund evaluates ESG factors and risks, using third-party data and internally-generated analysis, which may include assessments of a company’s alignment with international commitments, a review of ESG investment risk reports, and corporate engagement. At portfolio management’s discretion, the Fund will engage with a company’s senior management to seek to better understand improvements in ESG reporting and disclosure, environmental performance, and strategic positioning in relation to key sustainability trends. The Fund may invest in companies whose ESG practices are evolving, with the expectation that these engagement efforts will result in improvements over time, and will consider selling a security if a company is not responsive to such engagement efforts. The Fund does not consider ESG factors and risks in managing the Fund’s exposure to cash and cash equivalents and certain derivatives, such as forward currency contracts used for hedging purposes.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is a risk of significant deterioration in the company’s fundamentals, there is a change in business strategy or issuer-specific business outlook that affects the original investment case, or if a superior investment opportunity arises. The Fund will also consider selling a security if, in portfolio management’s opinion, the company’s business model no longer meets the investment criteria employed in managing the Fund.
The Fund may invest its assets in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests or to hedge portfolio risk. In particular, the Fund may invest in derivatives such as forward currency contracts to offset risks associated with currency exposure.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The Fund’s investment strategies could result in significant fluctuations of dividend income. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
11 | Janus Henderson Responsible International Dividend Fund

ESG Investment Risk.As a result of the Fund’s ESG-related strategy, the Fund may perform differently than funds that do not have an ESG-related strategy. Due to the ESG considerations and exclusionary criteria employed by the Fund, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. ESG-related information provided by issuers and third parties, which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to consider their environmental or social practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the issuers identified through the investment process employed by the Fund may fail to adhere to positive environmental or social practices, which may result in selling a security when it might otherwise be disadvantageous to do so.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
Issuer Concentration Risk.The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments.
Geographic Concentration Risk.To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.
Europe Risk.The Fund is subject to certain risks associated with Europe and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent. Changes in regulations on trade, decreasing imports or exports, changes in the exchange rate of European currencies, and recessions among European countries may have a significant adverse effect on the economies of other European countries. Western Europe has, in certain instances, been susceptible to serious financial hardship, high debt levels, and high levels of unemployment. The markets in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments.
Currency Risk.Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Dividend-Oriented Stocks Risk.Companies that have paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the security held by the Fund or the Fund receiving less income.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can
12 | Janus Henderson Responsible International Dividend Fund

continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Growth Securities Risk.Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole.
Depositary Receipts Risk.Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets.
Mid-Sized Companies Risk.Investments in securities issued by mid-sized companies may involve greater risks than are customarily associated with larger, more established companies. For example, mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by mid-sized companies tend to be more volatile than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Returns shown for periods prior to June 5, 2017, are those of Henderson Dividend & Income Builder Fund (the “Predecessor Fund”). The Predecessor Fund was advised by Henderson Global Investors (North America) Inc. and subadvised by Henderson Investment Management Limited. Class A Shares, Class C Shares, Class I Shares, and Class R6 Shares of the Predecessor Fund were reorganized into Class A Shares, Class C Shares, Class I Shares, and Class N Shares, respectively, of the Fund on June 2, 2017. Class A Shares, Class C Shares, and Class I Shares of the Predecessor Fund commenced operations with the Predecessor Fund’s inception on August 1, 2012. Class R6 Shares of the Predecessor Fund commenced operations on November 30, 2015. Class S Shares and Class T Shares of the Fund commenced operations on June 5, 2017.
The performance shown for Class A Shares for periods prior to June 5, 2017, reflects the performance of Class A Shares of the Predecessor Fund and is calculated using the fees and expenses of Class A Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class C Shares for periods prior to June 5, 2017, reflects the performance of Class C Shares of the Predecessor Fund and is calculated using the fees and expenses of Class C Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class I Shares for periods prior to June 5, 2017, reflects the performance of Class I Shares of the Predecessor Fund and is calculated using the fees and expenses of Class I Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class N Shares for periods prior to June 5, 2017, reflects the performance of Class R6 Shares of the Predecessor Fund and is calculated using the fees and expenses of Class R6 Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers, except that for periods prior to November 30, 2015, performance shown for Class N Shares reflects the performance of Class I Shares of the Predecessor Fund, calculated using the estimated fees and expenses of Class N Shares, net of any applicable fee and expense limitations or waivers.
The performance shown for Class S Shares for periods prior to June 5, 2017, reflects the performance of Class I Shares of the Predecessor Fund, calculated using the estimated fees and expenses of Class S Shares, net of any applicable fee and expense limitations or waivers.
The performance shown for Class T Shares for periods prior to June 5, 2017, reflects the performance of Class I Shares of the Predecessor Fund, calculated using the estimated fees and expenses of Class T Shares, net of any applicable fee and expense limitations or waivers.
Returns of the Fund will be different from the Predecessor Fund as they have different expenses.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective October 28, 2022, the Fund changed its investment strategy. Performance prior to October 28, 2022 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s (and the Predecessor Fund’s) past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

The Fund’s broad-based benchmark index is the MSCI World ex-USA Index. The index is described below.
The MSCI World ex-USA Index is designed to measure the equity market performance of developed market countries in North America, Europe, and the Asia/Pacific Region, excluding the United States.
After-tax returns are calculated using distributions for the Predecessor Fund’s Class I Shares for the period prior to June 5, 2017. If Class I Shares of the Fund had been available during periods prior to June 5, 2017, the distributions used to calculate the after-tax returns may have been different. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

Purchases, exchanges, and redemptions can generally be made only through institutional channels, such as financial intermediaries and retirement platforms. You should contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund. Requests must be received in good order by the Fund or its agents (financial intermediary or plan sponsor, if applicable) prior to the close of the trading session of the New York Stock Exchange in order to receive that day’s net asset value. For additional information, refer to “Purchases,” “Exchanges,” and/or “Redemptions” in the Prospectus.
Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase Class A Shares, Class C Shares, Class S Shares, Class I Shares, or Class T Shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any performance adjustments to management fees, fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.91% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 36% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing primarily in the common stocks of small companies and focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization for companies included in the Russell 2000® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $3 million to $13.14 billion. The 12-month average of the maximum market capitalization for companies included in the Russell 2000 Value Index for the one-year period ended June 30, 2024 was $8.48 billion. From time to time, the Fund may invest in shares of companies through initial public offerings. The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data,
19 | Janus Henderson Small Cap Value Fund

and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Small-Sized Companies Risk.Investments in securities issued by small-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
20 | Janus Henderson Small Cap Value Fund

Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund commenced operations on July 6, 2009. Class N Shares of the Fund commenced operations on May 31, 2012.
The performance shown for Class T Shares reflects the fees and expenses of Class T Shares, net of any applicable fee and expense limitations or waivers.
The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class R Shares reflects the performance of the Fund’s Class J Shares (formerly named Investor Shares) for periods prior to July 6, 2009, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
The performance shown for Class I Shares reflects the performance of the Fund’s Class J Shares (formerly named Investor Shares) for periods prior to July 6, 2009, calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.
The performance shown for Class N Shares reflects the performance of the Fund’s Class T Shares from July 6, 2009 to May 31, 2012, calculated using the fees and expenses of Class T Shares, net of any applicable fee and expense limitations or waivers. For periods prior to July 6, 2009, the performance shown for Class N Shares reflects the performance of the Fund’s Class J Shares (formerly named Investor Shares), calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, or Class N Shares of the Fund had been available during periods prior to May 31, 2012, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For

certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell 2000 Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell 2000 Value Index as a performance benchmark because the Russell 2000 Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell 2000 Value Index measures the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values.
After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding any performance adjustments to management fees, fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.74% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of small- and mid-sized companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization of companies included in the Russell 2500tm Value Index. The market capitalizations within the index will vary but, as of June 30, 2024, they ranged from approximately $3 million to $30.32 billion. The 12-month average of the maximum market capitalization of companies included in the Russell 2500 Value Index for the one-year period ended June 30, 2024 was $23.19 billion. The Fund focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund normally invests in a portfolio of 35-50 equity securities, which consist primarily of common stocks, but may also include other types of instruments. From time to time, the Fund may invest in shares of companies through initial public offerings.
The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data,
26 | Janus Henderson Small-Mid Cap Value Fund

and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Small- and Mid-Sized Companies Risk.Investments in securities issued by small- and mid-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Issuer Concentration Risk.The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those
27 | Janus Henderson Small-Mid Cap Value Fund

sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class T Shares of the Fund commenced operations with the Fund’s inception. Class N Shares of the Fund commenced operations on August 4, 2017.
The performance shown for Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class T Shares is calculated using the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The performance shown for Class N Shares for periods prior to August 4, 2017, reflects the performance of the Fund’s Class I Shares, calculated using the fees and expenses of Class N Shares, without the effect of any fee and expense limitations or waivers. If Class N Shares of the Fund had been available during periods prior to August 4, 2017, the performance may have been different.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower. Effective August 1, 2019, the Fund changed its investment strategy. Performance prior to August 1, 2019 reflects the Fund’s former strategy, and its performance may have differed if the Fund’s current strategy had been in place.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell 2500 Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell 2500 Value Index as a performance benchmark because the Russell 2500 Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell 2500 Value Index measures the performance of those Russell 2500 companies with lower price-to-book ratios and lower forecasted growth values.
After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class I Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class I Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

Additional information about the Funds
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Shareholder Fees” are fees paid directly from your investment and may include sales loads.
“Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by each Fund to the Adviser. Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund each pay an investment advisory fee rate that adjusts up or down by a variable rate of up to 0.15% (assuming constant assets) on a monthly basis based upon the Fund’s performance relative to its benchmark index during a measurement period. This base fee rate, prior to any performance adjustment, is 0.64% for Janus Henderson Mid Cap Value Fund, 0.72% for Janus Henderson Small Cap Value Fund, and 0.70% for Janus Henderson Small-Mid Cap Value Fund. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Distribution/Service (12b-1) Fees.” Because 12b-1 fees are charged as an ongoing fee, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. Distribution/Service (12b-1) Fees include a shareholder servicing fee of up to 0.25% for Class C Shares.
A contingent deferred sales charge of up to 1.00% may be imposed on certain redemptions of Class A Shares bought without an initial sales charge and then redeemed within 12 months of purchase. The contingent deferred sales charge is not reflected in the Example in each Fund Summary.
A contingent deferred sales charge of 1.00% generally applies on Class C Shares redeemed within 12 months of purchase. The contingent deferred sales charge may be waived for certain investors, as described in the Shareholder’s Guide.
“Other Expenses”
°
for Class A Shares, Class C Shares, and Class I Shares, may include administrative fees charged by intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds.
°
for Class S Shares, Class R Shares, and Class T Shares, include an administrative services fee of 0.25% of the average daily net assets of each class to compensate Janus Henderson Services US LLC (the “Transfer Agent”), the Funds’ transfer agent, for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of retirement plan participants, pension plan participants, or other underlying investors investing through institutional channels.
°
for all classes, include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that a Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. Such amounts are less than 0.01%.
°
for all classes, may include reimbursement to the Adviser of its out-of-pocket costs for services as administrator and to the Transfer Agent of its out-of-pocket costs for serving as transfer agent and providing, or arranging by others the provision of, servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse each Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus. Because a fee waiver and/or reimbursement will have a positive effect
32 | Janus Investment Fund

upon a fund’s performance, a fund that pays a performance-based investment advisory fee may experience a performance adjustment that is considered favorable to the Adviser as a result of a fee waiver and/or reimbursement that is in place during the period when the performance adjustment applies.
All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, a Fund will provide shareholders with at least 60 days’ notice prior to changing the 80% investment policy. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary sections, including the types of securities each Fund may invest in when pursuing its investment objective. This section also describes investment strategies and policies that the Funds may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since a Fund’s composition can change over time. Except for the Funds’ policies with respect to illiquid investments, borrowing, and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
Portfolio management for Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund primarily invests in the common stocks of companies and focuses on companies whose stock prices are believed to be undervalued or that have fallen out of favor with the market. Portfolio management looks for companies with strong fundamentals and competent management.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation. Portfolio management will generally consider selling a Fund holding if, among other things, the security reaches portfolio management’s price target, if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks, or if portfolio management finds a better investment opportunity. Portfolio management will also consider selling a Fund holding to meet redemptions.
A company may be considered attractively valued when, in the opinion of portfolio management, shares of the company are selling for a price that is below their intrinsic worth (“undervalued”). A company may be undervalued due to market or economic conditions, temporary earnings declines, unfavorable developments affecting the company, or other factors. Such factors may provide buying opportunities at attractive prices compared to historical or market price-earnings ratios, price/free cash flow, book value, or return on equity. Portfolio management believes that buying these securities at a price that is below their intrinsic worth may generate greater returns for a Fund than those obtained by paying premium prices for companies currently in favor in the market.
33 | Janus Investment Fund

Janus Henderson Responsible International Dividend Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of dividend-producing equity securities. The Fund’s investment approach (i) seeks to avoid companies and industries that it considers to be involved in business activities and behaviors that may be environmentally and/or socially harmful, and (ii) considers environmental, social, and governance (“ESG”) factors and a company’s management of ESG risks. The Fund primarily invests in equity securities of companies that are economically tied to countries outside of the United States, including investments in emerging markets. The Fund’s investments may be in non-U.S. currency or U.S. dollar-denominated. In pursuing its investment objective, portfolio management first seeks to identify equity securities of companies with attractive long-term business prospects that generate profits and produce attractive levels of dividend income. Although the Fund does not have a specific policy regarding the growth/value orientation or market capitalization of the companies in which it invests, portfolio management believes that focusing on dividend-producing equity securities will tend to lead to investments in mid-to-large capitalization “value” stocks (stocks of well-established, undervalued companies that portfolio management believes offer the potential for income and long-term capital appreciation). Portfolio management may, however, invest in smaller and less seasoned issuers and in stocks that are considered “growth” stocks.
Next, portfolio management applies broad-based negative screens, which incorporate third-party inputs, to seek to avoid companies and industries that are directly associated with business activities and behaviors that may be environmentally and/or socially harmful, subject to certain de minimis limits that may be quantitative (e.g., expressed as a percentage of a company’s revenues) or qualitative in nature. When an activity relates to a company’s revenues, a 10% threshold is applied. The qualitative assessment looks at the extent to which an “avoided” activity is part of a company’s business and whether a company is taking action to address and improve upon such activity. A current list of such business activities and behaviors, which may evolve over time, follows:
Adult entertainment;
Alcohol;
Animal testing for non-medical purposes;
Armaments;
Fossil fuel extraction and refining;
Fossil fuel power generation;
Fur;
Gambling; and
Tobacco.
The screening process is also used to exclude companies that are United Nations Global Compact violators and companies that are in breach of the Organization for Economic and Co-operation and Development Guidelines for Multinational Enterprises.
Portfolio management considers inputs from third-party data providers in implementing the Fund’s investment strategies. The third-party data providers used by portfolio management are disclosed in the Fund’s SAI and are subject to change over time.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is a risk of significant deterioration in the company’s fundamentals, there is a change in business strategy or issuer-specific business outlook that affects the original investment case, or if a superior investment opportunity arises. The Fund will also consider selling a security if, in portfolio management’s opinion, the company’s business model no longer meets the investment criteria employed in managing the Fund.
Cash Position
The Funds may not always stay fully invested. For example, when portfolio management believes that market conditions are unfavorable for investing, or when it is otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. Due to differing investment strategies, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
34 | Janus Investment Fund

In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Derivatives
A Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. A Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
Emerging Markets
Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Indexsm.
ESG Integration
As part of a Fund’s investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors may include corporate governance, political governance, executive pay, board structure and diversity, business ethics, corporate reporting, company culture, human capital management and diversity, community relations, human rights, exposure to climate change, biodiversity, and deforestation. Portfolio management focuses on the ESG Factors it considers most likely to have a material impact on the long-term financial performance of the issuer, which includes identifying ESG Factors attributable to a particular region, sector, industry, or issuer. To facilitate its assessment of ESG Factors, portfolio management uses issuer reports, third-party data and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio. Portfolio management may assess the relevance of ESG Factors to its fundamental research process differently across issuers, sectors, regions, and asset classes.
Exchange-Traded Funds
Certain Funds may invest in exchange-traded funds (“ETFs”) to gain exposure to a particular portion of the market. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of a Fund, which will be indirectly paid by such Fund. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. A Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
Each Fund may invest in foreign securities. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. The Funds may at times have significant foreign exposure, including exposure to emerging markets.
Illiquid Investments
A Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
35 | Janus Investment Fund

Initial Public Offerings and Secondary Offerings
Certain Funds may purchase shares issued as part of, or a short period after, a company’s initial public offering (“IPO”), and may at times dispose of those shares shortly after their acquisition. An IPO is the first sale of stock by a private company to the public. IPOs are often issued by smaller, younger companies seeking the capital to expand, but can also be done by large privately-owned companies looking to become publicly traded. Certain Funds may also purchase shares in offerings made by companies that are publicly traded (“secondary offerings”). Secondary offerings may be made by companies for a number of reasons, including as part of a refinancing, to raise capital for growth, and/or to provide existing shareholders with a way to register and sell restricted shares.
Leverage
Certain of a Fund’s investments, including derivatives and short sale transactions, involve the use of leverage. Leverage is investment exposure which exceeds the initial amount invested. Leverage occurs when a Fund increases its assets available for investment using derivatives, short sales, when-issued, delayed delivery, or forward commitment transactions, or other similar transactions. The use of other investment techniques can also create a leveraging effect on a Fund.
Portfolio Turnover
In general, each Fund intends to purchase securities for long-term investment, although, to a limited extent, a Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to shareholder purchases and redemptions), the nature of a Fund’s investments, and the investment style of portfolio management. Changes are normally made in a Fund’s portfolio whenever portfolio management believes such changes are desirable. Portfolio turnover rates are generally not a factor in making buy and sell decisions for the Funds.
Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in the acceleration of taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
REITs and Real Estate-Related Securities
Each Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
36 | Janus Investment Fund

Securities Lending
A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. A Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, a Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and a Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If a Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to a Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Short Sales
A Fund may invest in short positions through short sales of stocks and structured products, and through derivatives that include swaps, uncovered written calls, and futures. A Fund may also engage in short sales “against the box” and options for hedging purposes. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility.
A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the borrowed securities be returned to the lender on short notice, and the Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, a “short squeeze” can occur, which means that the demand is greater than the supply for the stock sold short. If a short squeeze occurs, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a fund that does not engage in short sales and may negatively affect the Fund’s performance.
A Fund may enter into a derivatives transaction to obtain short investment exposure to an underlying reference asset. If the value of the underlying reference asset on which a Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes a Fund to credit risk, counterparty risk, and leverage risk.
Special Situations
The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of portfolio management, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological
37 | Janus Investment Fund

advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.
Other Types of Investments
Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:
debt securities (such as bonds, notes, and debentures)
preferred stocks and securities convertible into common stocks or preferred stocks
indexed/structured securities (such as commercial and residential mortgage- and asset-backed securities)
pass-through securities including commercial and residential mortgage- and asset-backed securities and mortgage dollar rolls
securities purchased on a when-issued, delayed delivery, or forward commitment basis
equity and fixed-income securities issued in private placement transactions
Risks of the Funds
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. To varying degrees, the Funds may invest in stocks, fixed-income securities, money market instruments or cash/cash equivalents, and derivatives. The following information is intended to help you better understand some of the risks of investing in the Funds, including those risks that are summarized in the Fund Summary sections. This information also includes descriptions of other risks a Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, a Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of swaps, futures, and options). Each Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause a Fund to be more volatile than if it had not used leverage.
The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk. There is no guarantee that
38 | Janus Investment Fund

portfolio management’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.
Forward Foreign Currency Exchange Contract Risk.Forward foreign currency exchange contracts (“forward currency contracts”) involve the risk that unanticipated changes in currency prices may negatively impact a Fund’s performance. Moreover, there may be an imperfect correlation between a Fund’s portfolio holdings of securities quoted or denominated in a particular currency and any forward currency contracts entered into by the Fund, which will expose the Fund to risk of foreign exchange loss. The trading markets for forward currency contracts offer less protection against defaults than trading in currency instruments on an exchange. Because a forward currency contract is not guaranteed by an exchange or clearinghouse, a default on the contract could result in losses to a Fund and may force the Fund to cover its purchase or sale commitments, if any, at the current market price. In addition, forward currency contract markets can experience periods of illiquidity, which could prevent a Fund from divesting of a forward currency contract at the optimal time and may adversely affect a Fund’s returns and net asset value.
Emerging Markets Risk.Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
ESG Integration and Investment Risk.There is a risk that considering ESG Factors as part of a Fund’s investment process may fail to produce the intended results or that a Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require a Fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
39 | Janus Investment Fund

Janus Henderson Responsible International Dividend Fund has an ESG-related strategy and may employ exclusionary criteria to avoid investing in certain industries, activities, or assets considered by portfolio management to have a negative impact on society or the environment. This Fund is subject to similar risks as those Funds that consider ESG Factors as part of their investment process.
European Investments Risk.Exposure to investments in European countries may expose a Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. A Fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.
Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When a Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, a Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which a Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, a Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because a Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.
Foreign Exposure Risk.Within the parameters of its specific investment policies, each Fund may invest in foreign equity and debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:
Currency Risk.As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Foreign Market Risk.Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions.
40 | Janus Investment Fund

Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.
Geographic Concentration Risk.To the extent that a Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.
Political and Economic Risk.Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the U.S. Government on other countries or persons or issuers operating in such countries could restrict a Fund’s ability to buy affected securities or force a Fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, a Fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
Regulatory Risk.There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
Transaction Costs.Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
Industry and Sector Risk.Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase that Fund’s exposure to industry and sector risk.
Initial Public Offering and Secondary Offering Risk.A Fund’s purchase of shares issued in an IPO exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. Attractive IPOs are often oversubscribed and may not be available to the Funds, or may be available only in very limited quantities. The market for IPO issuers has been volatile, and share prices of newly public companies have fluctuated up and down significantly over short periods of time. There can be no assurance that the Funds will identify favorable IPO investment opportunities. In addition, under certain market conditions, a relatively small number of companies may issue securities in IPOs. Similarly, as the number of Funds to which IPO securities are allocated increases, the number of securities issued to any one Fund may decrease. In addition, as a fund increases in size, the impact of IPOs on the fund’s performance will generally decrease.
A Fund may purchase shares in secondary offerings. Secondary offerings may expose a Fund to some of the risks of IPOs. Participation in secondary offerings may have a magnified impact on the performance of a fund to the extent that it has a small asset base and the fund may not experience similar performance as its assets grow. Secondary offering shares frequently
41 | Janus Investment Fund

are volatile in price. As a result, a Fund may hold secondary offering shares for a very short period of time. This may increase the portfolio turnover rate of the Fund and may lead to increased expenses for the Fund, such as commissions and transaction costs. In addition, secondary offering shares can experience an immediate drop in value if the demand for the securities does not continue to support the offering price.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of a Fund’s shares. A Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares.
Leverage Risk.Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose a Fund to greater risk and increase its costs. The use of leverage may cause a Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act of 1940, as amended, and the rules thereunder. Increases and decreases in the value of a Fund’s portfolio will be magnified when the Fund uses leverage.
Liquidity Risk.A Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, a Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, a Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect a Fund’s value or prevent such Fund from being able to take advantage of other investment opportunities.
Liquidity risk may also refer to the risk that a Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of portfolio securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s net asset value, may increase brokerage costs, and may result in taxable capital gains.
Market Risk.The value of a Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict,
42 | Janus Investment Fund

resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Portfolio Management Risk.The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and research process employed for the Funds may fail to produce the intended results. Accordingly, the Funds may underperform benchmark indices or other funds with similar investment objectives.
REIT and Real Estate-Related Securities Risk.To the extent a Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which a Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. A Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing the return to the Fund on its investment in such company.
Small- and Mid-Sized Companies Risk.A Fund’s investments in securities issued by small- and mid-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on a Fund’s returns, especially as market conditions change.

Management of the Funds
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. The Adviser is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning the Funds’ investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of each Fund. In addition, the Adviser utilizes a personnel-sharing arrangement with its foreign (non-U.S.) affiliate, Janus Henderson Investors UK Limited (“JHIUKL”), pursuant to which one or more Janus Henderson employees, acting for JHIUKL, may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for JHIUKL, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to Janus Henderson Responsible International Dividend Fund on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the Securities and Exchange Commission (the “SEC”) that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of a Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate a Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that a Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to a Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for a Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Funds, including providing office space for the Funds and providing personnel to serve as officers to the Funds. The Funds reimburse the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Funds’ Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Funds. The Funds pay these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Funds.
Management expenses
Each Fund pays the Adviser an investment advisory fee and incurs expenses, including the distribution and shareholder servicing fees (12b-1 fee), administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay.
The following tables reflect each Fund’s contractual investment advisory fee rate or base fee rate, as applicable (expressed as an annual rate), as well as the actual compensation rate paid by each Fund to the Adviser after any applicable fee waivers and/or expense reimbursements.

Performance-Based Investment Advisory Fee
As reflected in the table below, Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund each pay an investment advisory fee rate that may adjust up or down based on each Fund’s performance relative to the cumulative investment record of its performance fee benchmark index (referred to in this section as the “benchmark index”) over a rolling 36-month performance measurement period. The second column in the table below shows each Fund’s base fee rate. The third column shows the full performance rate for outperformance or underperformance during the measurement period relative to each Fund’s respective benchmark index. The fourth column shows the performance adjusted investment advisory fee rate, which is equal to each Fund’s base fee rate plus or minus the performance adjustment over the period without any fee waivers. The fifth column shows the actual compensation rate paid by each Fund after any applicable fee waivers and/or expense reimbursements as of the end of the fiscal year.
As an example, if a Fund outperformed its benchmark index over the performance measurement period by its full performance rate (listed in the table below), the advisory fee would increase by 0.15% (assuming constant assets). Conversely, if a Fund underperformed its benchmark index over the performance measurement period by its full performance rate (listed in the table below), the advisory fee would decrease by 0.15% (assuming constant assets). Actual performance within the full range of the full performance rate may result in positive or negative incremental adjustments to the advisory fee of greater or less than 0.15%. Additional details discussing the performance fee are included below with further description in the SAI.

Due to the restatement of the Fund’s investment advisory fee, the investment advisory fee rates stated above will differ from those in the Fund’s expense table earlier in the Prospectus.
For Janus Henderson Mid Cap Value Fund, Janus Henderson Small Cap Value Fund, and Janus Henderson Small-Mid Cap Value Fund, the investment advisory fee rate is determined by calculating a base fee (shown in the previous table) and applying a performance adjustment (described in further detail below). The performance adjustment either increases or decreases the base fee depending on how well each Fund has performed relative to its benchmark index as shown below:
Fund Name
Benchmark Index
Janus Henderson Mid Cap Value Fund
Russell Midcap Value Index
Janus Henderson Small Cap Value Fund
Russell 2000 Value Index

Russell 2500 Value Index
The calculation of the performance adjustment applies as follows:
Investment Advisory Fee = Base Fee Rate +/– Performance Adjustment
45 | Janus Investment Fund

The investment advisory fee rate paid to the Adviser by each Fund in the table above consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets based on the Fund’s relative performance compared to the cumulative investment record of its benchmark index over a 36-month rolling performance measurement period.
No Performance Adjustment is applied unless the difference between a Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to a Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase the Adviser’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease the Adviser’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of a Fund is calculated net of expenses whereas a Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of a Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment advisory fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, the Adviser would reimburse the applicable Fund.
The application of an expense limit, if any, will have a positive effect upon a Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to the Adviser may, under some circumstances, exceed the cumulative dollar amount of management fees waived by the Adviser.
The investment performance of a Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. After the Adviser determines whether a particular Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares against the cumulative investment record of that Fund’s benchmark index, the Adviser applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to the Adviser since it depends on the performance of each Fund relative to the record of the Fund’s benchmark index and future changes to the size of each Fund.
A discussion regarding the basis for the Trustees’ approval of the Funds’ investment advisory agreements is included in each Fund’s semiannual report (for the period ended December 31, 2023) and in the Funds’ financial statements (for the period ended June 30, 2024, and moving forward). You can request the Funds’ semiannual reports or financial statements (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus Henderson representative at 1-877-335-2687. This information is also available, free of charge, at janushenderson.com/info.
Expense Limitations
The Adviser has contractually agreed to waive the advisory fee payable by each Fund and/or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding any performance adjustments to management fees, the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below. The Adviser has agreed to continue each waiver for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. For information about how the expense limit affects the total

The Fund pays an investment advisory fee rate that may adjust up or down based on the Fund’s performance relative to its benchmark index during a measurement period.

Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund(s) that they manage, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that a Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to that Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.

Other information
CLOSED FUND POLICIES
A Fund may limit sales of its Shares to new investors. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Funds
The Funds are distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Funds, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within a single Fund.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well. The date you receive your distribution may vary depending on how your intermediary processes trades. Please consult your intermediary for details.
How Distributions Affect a Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund without any sales charge. To receive distributions in cash, contact your financial intermediary, or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with a Fund. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Funds. The following is a general discussion of certain federal income tax consequences of investing in the Funds. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment
50 | Janus Investment Fund

income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of a Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, a Fund that invests in REITs is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of a Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Funds may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), a Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary (or the Fund, if you hold Class N Shares directly with a Fund) will report cost basis information to you and to the IRS. Your intermediary (or the Fund) will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method, unless you hold Class N Shares directly with a Fund in which case the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If a Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.
51 | Janus Investment Fund

Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s guide
With certain exceptions, the Funds are generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Funds require that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with a Fund.
The Funds offer multiple classes of shares in order to meet the needs of various types of investors.
Class A Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. Class A Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services on behalf of their clients. In addition, Class A Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. Class A Shares may be offered without an initial sales charge to certain classes of investors such as purchases through certain retirement platforms, certain self-directed brokerage platforms where the financial intermediary is the broker of record, or fee-based platforms. See “Qualifying for a Waiver or Reduction of Class A Shares Sales Charge” in this Shareholder’s Guide for additional details.
Class C Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, and bank trust platforms. Class C Shares pay up to 0.75% of net assets for payment to financial intermediaries for the provision of distribution services and up to 0.25% of net assets for the provision of shareholder services on behalf of their clients. In addition, Class C Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class C Shares are closed to investments by new employer-sponsored retirement plans and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares. Other share classes described in this Prospectus as eligible for investment by retirement plans are unaffected by this closure.
Class C Shares currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares. For more information, please refer to “Conversion of Class C Shares to Class A Shares.”
Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class S Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. Class I Shares may also be available to retail investors purchasing in qualified or nonqualified accounts where such accounts are held through an omnibus account at your broker or financial intermediary. For more information please refer to Appendix A which accompanies this Prospectus. Class I Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. In addition to these fees and expenses paid by Class I Shares, your broker or financial intermediary may impose a commission or other sales charge on purchases. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative.
Class N Shares are generally available only to financial intermediaries purchasing on behalf of: 1) certain adviser-assisted, employer-sponsored retirement plans, including 401(k) plans, 457 plans, 403(b) plans, Taft-Hartley multi-employer plans, profit-sharing and money purchase pension plans, defined benefit plans, and certain welfare benefit plans, such as health savings accounts, and nonqualified deferred compensation plans; and 2) institutional investors and retail investors purchasing in qualified or nonqualified accounts, whose accounts are held through an omnibus account at their financial intermediary,
53 | Janus Investment Fund

and where the financial intermediary requires no payment or reimbursement from the Funds, the Adviser or its affiliates, for distribution-related or other shareholder services. Your broker or financial intermediary may impose a commission or other sales charge on purchases of Class N Shares. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative. Class N Shares also are available to Janus Henderson proprietary products. Class N Shares also are available to certain direct institutional investors approved by the Distributor including, but not limited to, corporations, certain retirement plans, public plans, and foundations and endowments, subject to minimum investment requirements.
Class R Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms. Class R Shares pay up to 0.50% of net assets to financial intermediaries for the provision of distribution services and, to a certain extent, shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of the plan or plan participants.
Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class T Shares pay up to 0.25% of net assets to financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
The Shares are not offered directly to individual investors. Consult with your financial intermediary representative for additional information on whether the Shares are an appropriate investment choice. Certain funds may not be available through certain of these intermediaries and not all financial intermediaries offer all classes of shares. If your financial intermediary offers more than one class of shares, you should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. For instructions on how to purchase, exchange, or redeem Shares, contact your financial intermediary or refer to your plan documents. For Class N Shares held directly with a Fund, please contact a Janus Henderson representative at 1-800-333-1181.
Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. A Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which a Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by a Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.
The price you pay for purchases of Shares is the public offering price, which is the NAV next calculated after your request is received in good order by a Fund or its agents, plus, for Class A Shares, any applicable initial sales charge. The price you pay to sell Shares is also the NAV, although for Class A Shares and Class C Shares, a contingent deferred sales charge may be taken out of the proceeds. For Class I Shares or Class N Shares, although purchases and redemptions are made at the net asset value calculated after your order is received by the Funds, you may be charged a commission by your broker or other financial institution. The nature and amount of the commission and the times at which it may be collected are determined by your broker. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares. In order to receive a day’s price, your order must be received in good order by a Fund or its agents by the close of the trading session of the NYSE.
Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last
54 | Janus Investment Fund

sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of a Fund’s portfolio securities and the reflection of such change in a Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of a Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by a Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used. Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor.

customers. The Funds are not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Choosing a share class
Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, Class R Shares, and Class T Shares are offered by this Prospectus. The Funds offer multiple classes of shares in order to meet the needs of various types of investors. For more information about these classes of Shares and whether or not you are eligible to purchase these Shares, please call 1-877-335-2687.
Each class represents an interest in the same portfolio of investments, but has different charges and expenses, allowing you to choose the class that best meets your needs. For an analysis of fees associated with an investment in each share class or other similar funds, please visit www.finra.org/fundanalyzer. When choosing a share class, you should consider:
how much you plan to invest;
how long you expect to own the shares;
the expenses paid by each class; and
for Class A Shares and Class C Shares, whether you qualify for any reduction or waiver of any sales charges.
You should also consult your financial intermediary about which class is most suitable for you. In addition, you should consider the factors below with respect to each class of Shares:

(2) 
Class A, Class C, Class S, and Class T shares held through certain supermarket and/or self-directed brokerage accounts, or through wrap programs, may not be subject to this minimum. Please contact your financial intermediary for more information. For Class R shareholders, there is no investment minimum for defined contribution plans. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information regarding account minimums.
(3) 
In addition to these fees and expenses, your broker or financial intermediary may impose a commission or other sales charge on your purchases of Class I Shares or Class N Shares. The nature and amount of such commission or other sales charge is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative.
(4) 
Exceptions to this minimum may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts.
(5) 
Investors in certain tax-advantaged accounts or accounts held through certain wrap programs or bank trust platforms may not be subject to this minimum.
Distribution, servicing, and administrative fees
Distribution and Shareholder Servicing Plans
Under separate distribution and shareholder servicing plans adopted in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended, for Class A Shares, Class S Shares, and Class R Shares (each a “Plan”) and Class C Shares (the “Class C Plan”), each Fund pays the Distributor a fee for the sale and distribution and/or shareholder servicing of the Shares based on the average daily net assets of each, at the following annual rates:
Class
12b-1 Fee for the Funds
Class A Shares
0.25%
Class C Shares
1.00%(1)
Class S Shares
0.25%
Class R Shares
0.50%
(1) 
Up to 0.75% of this fee is for distribution services and up to 0.25% of this fee is for shareholder services.
Under the terms of each Plan, the Trust is authorized to make payments to the Distributor for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Funds.
The Distributor is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although the Distributor may, pursuant to a written agreement between the Distributor and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.
Financial intermediaries may from time to time be required to meet certain criteria in order to receive 12b-1 fees. The Distributor is entitled to retain some or all fees payable under each Plan in certain circumstances, including when there is no broker of record or when certain qualification standards have not been met by the broker of record.
Because 12b-1 fees are paid out of a Fund’s assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.
Administrative Fees
Class A Shares, Class C Shares, and Class I Shares
Certain, but not all, intermediaries may charge fees for administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided by intermediaries on behalf of shareholders of the Funds. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent pays these administrative fees to intermediaries on behalf of the Funds. The Transfer Agent is then reimbursed by the Funds for such payments. Because the form and amount charged varies by intermediary, the amount of the administrative fee borne by the class is an average of all fees charged by intermediaries. In the event an intermediary receiving payments from the Transfer Agent on behalf of the Funds converts from a networking structure to an omnibus account structure, or otherwise
58 | Janus Investment Fund

experiences increased costs, fees borne by the Shares may increase. The Funds’ Trustees have set limits on fees that the Funds may incur with respect to administrative fees paid for omnibus or networked accounts. Such limits are subject to change by the Trustees in the future.
Class S Shares, Class R Shares, and Class T Shares
The Transfer Agent receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class S Shares, Class R Shares, and Class T Shares of each Fund for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds. Order processing includes the submission of transactions through the NSCC or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent expects to use all or a significant portion of this fee to compensate intermediaries and retirement plan service providers for providing these services to their customers who invest in the Funds. The Transfer Agent or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to the Funds.
For all share classes, the Transfer Agent also seeks reimbursement for costs it incurs as transfer agent and for providing servicing.
Payments to financial intermediaries by the Adviser or its affiliates
From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries that sell certain classes of Shares of the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Sales- and asset-based payments currently range up to 25 basis points on sales and up to 20 basis points on average annual net assets of shares held through the intermediary and are subject to change. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus Henderson funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Payments made with respect to certain classes of Shares may create an incentive for an intermediary to promote or favor other share classes of the Janus Henderson funds. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries, including, but not limited to, the share class or share classes selected by the financial intermediary for a particular channel, platform or investor type, whether such class is open to new investors on a particular platform or channel, the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness of the intermediary to cooperate with the Adviser’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors may change from time to time. Broker-dealer firms currently receiving or expected to receive these fees are listed in the SAI.
In addition, the Adviser, the Distributor, or their affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the NSCC or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services.
The Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates
59 | Janus Investment Fund

with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments, reimbursements, and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. However, as described elsewhere in this Prospectus, your financial adviser and/or his or her firm may also receive 12b-1 fees and/or administrative services fees in connection with your purchase and retention of Janus Henderson funds. When such fees are combined with the payments described above, the aggregate payments being made to a financial intermediary may be substantial. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
With the exception of Class N Shares, purchases of Shares may generally be made only through institutional channels such as financial intermediaries and retirement platforms. Class N Shares may be purchased directly with the Funds in certain circumstances as described in the eligibility discussion at the beginning of this “Shareholder’s Guide” section. Contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with the Adviser or refer to your plan documents for information on how to invest in each Fund, including additional information on minimum initial or subsequent investment requirements. Under certain circumstances, a Fund may permit an in-kind purchase of Shares. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Funds’ behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Funds or that provide services in connection with investments in the Funds. You should consider such arrangements when evaluating any recommendation of the Funds.
Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) is required to verify certain information on your account application as part of its Anti-Money
60 | Janus Investment Fund

Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) may temporarily limit additional share purchases. In addition, your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary (or a Janus Henderson representative, if you hold Class N Shares directly with a Fund) if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Minimum Investment Requirements
Class A Shares, Class C Shares, Class S Shares, and Class T Shares
The minimum investment is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. In addition, shares held through certain supermarket and/or self-directed brokerage accounts, or through wrap programs, may not be subject to these minimums. Investors should refer to their intermediary for additional information.
The maximum purchase in Class C Shares is $500,000 for any single purchase. The sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $500,000 of Fund shares. Effective on or about December 9, 2024, the maximum purchase in Class C Shares will change to $250,000 for any single purchase. At that time, the sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $250,000 of Fund shares.
Class I Shares
Accounts offered through an intermediary institution must meet the minimum investment requirements of $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Directors, officers, and employees of Janus Henderson Group plc (“JHG”) and its affiliates, as well as Trustees and officers of the Funds, may purchase Class I Shares through certain financial intermediaries’ institutional platforms. For more information about this program and eligibility requirements, please contact a Janus Henderson representative at 1-800-333-1181. Exceptions to these minimums may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts. For additional information, contact your intermediary, plan sponsor, or administrator, as applicable.
Class N Shares
For retail investors whose accounts are held through an omnibus account at their financial intermediary, the minimum investment is $2,500 per Fund account. Investors in certain tax-advantaged accounts or accounts held through certain wrap programs or bank trust platforms may not be subject to this minimum. For institutional investors investing directly with a Fund, the minimum investment is $1 million per Fund account. There is no investment minimum for adviser-assisted, employer-sponsored retirement plans, including health savings accounts. For additional information, contact your intermediary, plan sponsor, administrator, or a Janus Henderson representative, as applicable.
Class R Shares
There is no investment minimum for investors in a defined contribution plan. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information regarding account minimums. For all other account types, the minimum investment is $2,500.
Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class T Shares
Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject
61 | Janus Investment Fund

to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. If you hold Class N Shares directly with a Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Each Fund reserves the right to change the amount of these minimums or maximums from time to time or to waive them in whole or in part.
Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus Henderson representative for details.
Initial Sales Charge
Class A Shares
An initial sales charge may apply to your purchase of Class A Shares of the Funds based on the amount invested, as set forth in the table below. The sales charge is allocated between the Distributor and your financial intermediary. Sales charges, as expressed as a percentage of offering price and as a percentage of your net investment, are shown in the table. The dollar amount of your initial sales charge is calculated as the difference between the public offering price and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding.

A contingent deferred sales charge of 1.00% may apply to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase.
For purchases of Class A Shares of $1,000,000 or greater, from its own assets, the Distributor generally pays financial intermediaries commissions as follows:
1.00% on amounts of $1,000,000 but under $4,000,000;
0.50% on amounts of $4,000,000 but under $10,000,000;
0.25% on amounts of $10,000,000 and above.
The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.

Effective on or about December 9, 2024, for purchases of Class A Shares of $250,000 or greater, from its own assets, the Distributor generally pays financial intermediaries commissions as follows:
1.00% on amounts of $250,000 but under $4,000,000;
0.50% on amounts of $4,000,000 but under $10,000,000;

The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.
Qualifying for a Waiver or Reduction of Class A Shares Sales Charge
Class A Shares of the Funds may be purchased without an initial sales charge by the following persons (and their family members): (i) registered representatives and other employees of intermediaries that have selling agreements with the Distributor to sell Class A Shares; (ii) directors, officers, and employees of JHG and its affiliates; and (iii) Trustees and officers of the Trust. A “family member” includes, but is not necessarily limited to (based on the reasonable discretion of the Adviser), a qualifying person’s sibling, spouse or domestic partner, lineal ascendant (mother, father, grandmother, grandfather, great-grandmother, great-grandfather), lineal descendant (son, daughter, step-son, step-daughter, grandson, granddaughter, great-grandson, great-granddaughter) or any sibling, spouse or domestic partner of a family member who is a lineal descendant or ascendant of a qualifying person. In addition, the initial sales charge may be waived on purchases of Class A Shares by the following persons: (i) investors purchasing Class A Shares through financial intermediaries on behalf of certain adviser-assisted, employer-sponsored retirement plans, including defined contribution plans, defined benefit plans and other welfare benefit plans such as health savings accounts and voluntary employees’ beneficiary association trust accounts; (ii) investors purchasing Class A Shares through a financial intermediary’s self-directed brokerage platform where the financial intermediary is the broker of record; and (iii) investors purchasing Class A Shares through fee-based broker-dealers or financial advisors, primarily on their advisory account platform(s) where such broker-dealer or financial advisor imposes additional fees for services connected to the advisory account. Adviser-assisted, employer-sponsored defined contribution plans include, for example, 401(k) plans, 457 plans, 403(b) plans, profit sharing and money purchase pension plans. For purposes of qualifying for a waiver of the initial sales charge, the following retirement accounts are not eligible: 403(b) custodial accounts where shares are held on behalf of the individual, and not on behalf of the plan or plan trust, SEP IRAs, Simple IRAs, SAR-SEPs, or Keogh plans. To facilitate the waiver of a sales charge, the Distributor requires an agreement with the financial intermediary submitting trades on behalf of eligible investors.
You may be able to lower your Class A Shares sales charge under certain circumstances. For example, you can combine Class A Shares and Class C Shares you already own (either in these Funds or certain other Janus Henderson funds) with your current purchase of Class A Shares of the Funds and certain other Janus Henderson funds (including Class C Shares of those funds) to take advantage of the breakpoints in the sales charge schedule as set forth above. Certain circumstances under which you may combine such ownership of Shares and purchases are described below. Contact your financial intermediary for more information.
In order to obtain a sales charge discount, you should inform your financial intermediary of other accounts in which there are Fund holdings eligible to be aggregated to meet a sales charge breakpoint. These other accounts may include the accounts
63 | Janus Investment Fund

described under “Aggregating Accounts.” You may need to provide documents such as account statements or confirmation statements to prove that the accounts are eligible for aggregation. The Letter of Intent described below requires historical cost information in certain circumstances. You should retain records necessary to show the price you paid to purchase Fund shares, as the Funds, their agents, or your financial intermediary may not retain this information.
Right of Accumulation.You may purchase Class A Shares of a Fund at a reduced sales charge by aggregating (i) the dollar amount of the new purchase (measured by the offering price) with (ii) your holdings in all Class A Shares of the Fund and certain other classes (Class A Shares and Class C Shares of the Trust) of Janus Henderson funds held by you, and held in the accounts identified under “Aggregating Accounts” (“collective holdings”). Subject to your financial intermediary’s or record keeper’s capabilities, collective holdings will be calculated as the higher of (i) the current value of such holdings (the market value) as of the day prior to your new purchase or (ii) the amount initially invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the cost value). The applicable sales charge will be applied to such aggregated amount. In order for your purchases and collective holdings to be aggregated for purposes of qualifying for a reduced sales charge, they must have been made through one financial intermediary and you must provide sufficient information to your financial intermediary at the time of purchase to permit verification that the purchase qualifies for the reduced sales charge. The qualification of a purchase for the reduced sales charge does not ensure the future availability of the right of accumulation, which is subject to modification or discontinuance at any time.
Letter of Intent.You may obtain a reduced sales charge on Class A Shares by signing a Letter of Intent indicating your intention to purchase $50,000 or more of Class A Shares (including Class A Shares in other series of the Trust) over a 13-month period. The term of the Letter of Intent will commence upon the date you sign the Letter of Intent. Investments made prior to the signing date are not aggregated with, and are not eligible to be included toward, the investment goal.
You must refer to such Letter when placing orders. With regard to a Letter of Intent, the amount of investment for purposes of applying the sales load schedule includes (i) the historical cost (what you actually paid for the shares at the time of purchase, including any sales charges) of all Class A Shares acquired during the term of the Letter of Intent, minus (ii) the value of any redemptions of Class A Shares made during the term of the Letter of Intent. Capital appreciation, capital gains, and reinvested dividends earned during the Letter of Intent period do not apply toward its completion. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. A portion of shares purchased may be held in escrow to pay for any sales charge that may be applicable. If the goal is not achieved within the period, you must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed. Please contact your financial intermediary to obtain a Letter of Intent application.
Aggregating Accounts.To take advantage of lower Class A Shares sales charges on large purchases or through the exercise of a Letter of Intent or right of accumulation, investments made by you, your spouse, and your children under age 21 may be aggregated if made for your own account(s) and/or certain other accounts such as:
trust accounts established by the above individuals (or the accounts of the primary beneficiary of the trust if the person who established the trust is deceased);
solely controlled business accounts; and
single participant retirement plans.
To receive a reduced sales charge under rights of accumulation or a Letter of Intent, you must notify your financial intermediary of any eligible accounts that you, your spouse, and your children under age 21 have at the time of your purchase.
You may access information regarding sales loads, breakpoint discounts, and purchases of the Funds’ shares, free of charge, and in a clear and prominent format, on our website at janushenderson.com/breakpoints, and by following the appropriate hyperlinks to the specific information.
Conversion of Class C Shares to Class A Shares
The Funds currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month of the eighth anniversary of
64 | Janus Investment Fund

the date of purchase. Class C Shares purchased through the reinvestment of dividends and other distributions on Class C Shares will convert to Class A Shares at the same time as the Class C Shares with respect to which they were purchased.
For Class C Shares held in omnibus accounts on intermediary platforms, the Funds will rely on these intermediaries to implement this conversion feature. Your financial intermediary may have separate policies and procedures as to when and how Class C Shares may be converted to Class A Shares. Please contact your financial intermediary for additional information.
It is expected that the conversion of Class C Shares to Class A Shares of the same Fund will not result in a taxable event. Please consult your tax adviser for further information.
Commission on Class C Shares
The Distributor may compensate your financial intermediary at the time of sale at a commission rate of 1.00% of the net asset value of the Class C Shares purchased. Service providers to financial intermediaries will not receive this amount if they receive 12b-1 fees from the time of initial investment of assets in Class C Shares.
Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (“CDSC”) waivers. In all instances, it is the shareholder’s responsibility to notify a Fund, or the shareholder’s financial intermediary at the time of purchase, of any relationship or other facts qualifying the shareholder for sales charge waivers or discounts. Certain sales charge waivers and/or discounts are described in Appendix A – Intermediary Sales Charge Waivers and Discounts. These sales charge waivers and/or discounts are available only if you purchase your shares through the designated intermediaries. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares through another intermediary to receive these waivers or discounts.
Exchanges
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with a Fund or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received. A Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
You must meet the minimum investment amount for each fund.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds will work with intermediaries to apply the Funds’ exchange limits. However, the Funds may not always have the ability to monitor or enforce the trading activity in such accounts.
Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Class C Shares are closed to investments by new employer-sponsored retirement plans, and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares.
65 | Janus Investment Fund

Your Class C Shares that have been held for eight years will automatically convert to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month in which the eighth anniversary of the date of purchase occurs. For more information refer to “Conversion of Class C Shares to Class A Shares.”
Waiver of Sales Charges
Class A Shares received through an exchange of Class A Shares of another fund of the Trust will not be subject to an initial sales charge. In addition, Class A Shares received through an exchange of Class C Shares due to an intermediary-driven conversion or an automatic conversion after eight years, or a conversion from a fee-based account to a brokerage account, will not be subject to an initial sales charge. Class A Shares or Class C Shares received through an exchange of Class A Shares or Class C Shares, respectively, of another fund of the Trust will not be subject to any applicable CDSC at the time of the exchange. CDSC applicable to redemptions of Class A Shares or Class C Shares will continue to be measured on the Shares received by exchange from the date of your original purchase. For more information about the CDSC, please refer to “Redemptions.” While Class C Shares do not have any front-end sales charges, their higher annual fund operating expenses mean that over time, you could end up paying more than the equivalent of the maximum allowable front-end sales charge.
Redemptions
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Funds.
Redemptions, like purchases, may generally be effected only through financial intermediaries, retirement platforms, and by certain direct institutional investors holding Class N Shares. Please contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with a Fund or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of each Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by a Fund or its agents. Redemption proceeds, less any applicable CDSC for Class A Shares or Class C Shares, will normally be sent within two business days following receipt of the redemption order. The Funds typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. If you hold Class N Shares directly with a Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these large shareholders of their holdings in a Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect a Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In
66 | Janus Investment Fund

addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If a Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Systematic Withdrawal Plan
Class A Shares and Class C Shares
You may arrange for periodic redemptions of Class A Shares or Class C Shares by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Any resulting CDSC may be waived, however, the maximum annual rate at which shares subject to a CDSC may be redeemed, pursuant to a systematic withdrawal plan, without paying a CDSC, is 12% of the net asset value of the account. Certain other terms and minimums may apply. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Class S Shares, Class I Shares, Class N Shares, Class R Shares, and Class T Shares
You may arrange for periodic redemptions by authorizing your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus Henderson representative for details.
Contingent Deferred Sales Charge
Class A Shares and Class C Shares
A 1.00% CDSC may be deducted with respect to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase, unless any of the CDSC waivers listed apply. A 1.00% CDSC will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless a CDSC waiver applies. The CDSC will be based on the lower of the original purchase price or the value of the redemption of the Class A Shares or Class C Shares redeemed, as applicable.
CDSC Waivers
There are certain cases in which you may be exempt from a CDSC charged to Class A Shares and Class C Shares. Among others, these include:
Upon the death or disability of an account owner;
Retirement plans and certain other accounts held through a financial intermediary where no sales charge or commission was paid on the purchase of such shares;
Retirement plan shareholders taking required minimum distributions;
The redemption of Class A Shares or Class C Shares acquired through reinvestment of Fund dividends or distributions;
67 | Janus Investment Fund

The portion of the redemption representing appreciation as a result of an increase in NAV above the total amount of payments for Class A Shares or Class C Shares during the period during which the CDSC applied; or
If a Fund chooses to liquidate or involuntarily redeem shares in your account.
To keep the CDSC as low as possible, Class A Shares or Class C Shares not subject to any CDSC will be redeemed first, followed by shares held longest.
Reinstatement Privilege
For each redemption of Class A Shares, you have a one-time right to reinvest the proceeds of such redemption into Class A Shares of the same or another fund within 90 days of the redemption date at the current NAV (without an initial sales charge). You will not be reimbursed for any CDSC paid on your redemption of Class A Shares.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Funds are intended for long-term investment purposes, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies and procedures may be cancelled or rescinded by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Funds are also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Funds monitor for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds at all times reserve the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund.
The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.
In an attempt to deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Funds’ excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Funds by a collective investment trust managed by the Adviser; (iv) transactions in the Funds by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
68 | Janus Investment Fund

The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.
Excessive Trading Risks
Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of a Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by a Fund despite the Funds’ adoption of policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Funds to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of each Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for each Fund at janushenderson.com/info. A complete schedule of each Fund’s portfolio holdings is also available in the annual and semiannual financial statements included in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. Each Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation) and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom equity securities ranked by performance attribution, including the percentage attribution to Fund performance, average Fund weighting, and other relevant data points, may be provided monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Funds’ Chief Compliance Officer or a delegate. Such exceptions may
69 | Janus Investment Fund

be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.
Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with a Fund) is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with a Fund) is responsible for providing annual and semiannual reports of the Funds that you have authorized for investment. Please contact your financial intermediary or plan sponsor (or the Adviser) to obtain these reports. The Funds’ fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with a Fund) is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor (or the Adviser) is unable to locate the shareholder, then the financial intermediary or plan sponsor (or the Adviser) is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Financial highlights
The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if applicable. The information for the Funds for the fiscal periods ended June 30 has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in each Fund’s Form N-CSR and is incorporated by reference into the SAI.
The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in the Shares of the Funds (assuming reinvestment of all dividends and distributions).

Appendix A – intermediary sales charge waivers and discounts
AMERIPRISE FINANCIAL
The following information is provided by Ameriprise Financial:
Sales Charge Reductions and Waivers Available from Certain Financial Intermediaries
The availability of certain sales charge reductions and waivers will depend on whether you purchase fund shares directly from the fund or through a financial intermediary. Financial intermediaries may have different policies and procedures regarding the availability of front-end sales load reductions or waivers or CDSC waivers, which are described below. In all instances, it is the investor’s responsibility to notify the fund or the investor’s financial intermediary at the time of purchase of any relationship or other facts qualifying the investor for sales charge reductions or waivers. For reductions or waivers not available through a particular financial intermediary, investors will have to purchase fund shares directly through another financial intermediary to receive these reductions or waivers.
*********
Ameriprise Financial
Front-end sales charge reductions on Class A shares purchased through Ameriprise Financial
Shareholders purchasing Class A shares of the fund through an Ameriprise Financial platform or account are eligible only for the following sales charge reductions, which may differ from those disclosed elsewhere in this prospectus or the SAI. Such shareholders can reduce their initial sales charge on the purchase of Class A shares as follows:
Transaction size breakpoints, as described in this prospectus or the SAI.
Rights of accumulation (ROA), as described in this prospectus or the SAI.
Letter of intent, as described in this prospectus or the SAI.
Front-end sales charge waivers on Class A shares purchased through Ameriprise Financial
Shareholders purchasing Class A shares of the fund through an Ameriprise Financial platform or account are eligible only for the following sales charge waivers, which may differ from those disclosed elsewhere in this prospectus or the SAI.

shares purchased by employer-sponsored retirement plans (e.g., 401(k) plans, 457 plans, employer- sponsored 403(b) plans, profit sharing and money purchase pension plans and defined benefit plans). For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs or SAR-SEPs.
shares purchased through reinvestment of capital gains and dividend reinvestment when purchasing shares of the same fund (but not any other fund within the same fund family).
shares exchanged from Class C shares of the same fund in the month of or following the seven-year anniversary of the purchase date. To the extent that this prospectus elsewhere provides for a waiver with respect to such shares following a shorter holding period, that waiver will apply to exchanges following such shorter period. To the extent that this prospectus elsewhere provides for a waiver with respect to exchanges of Class C shares for load waived shares, that waiver will also apply to such exchanges.
shares purchased by employees and registered representatives of Ameriprise Financial or its affiliates and their immediate family members.
shares purchased by or through qualified accounts (including IRAs, Coverdell Education Savings Accounts, 401(k)s, 403(b) TSCAs subject to ERISA and defined benefit plans) that are held by a covered family member, defined as an Ameriprise Financial advisor and/or the advisor’s spouse, advisor’s lineal ascendant (mother, father, grandmother, grandfather, great grandmother, great grandfather), advisor’s lineal descendant (son, step-son, daughter, step-daughter, grandson, granddaughter, great grandson, great granddaughter) or any spouse of a covered family member who is a lineal descendant.
shares purchased from the proceeds of redemptions from another fund in the same fund family, provided (1) the repurchase occurs within 90 days following the redemption, (2) the redemption and purchase occur in the same account, and (3) redeemed shares were subject to a front-end or deferred sales load (i.e. Rights of Reinstatement).
CDSC waivers on Class A and C shares purchased through Ameriprise Financial
97 | Janus Investment Fund

Fund shares purchased through an Ameriprise Financial platform or account are eligible only for the following CDSC waivers, which may differ from those disclosed elsewhere in this prospectus or the SAI:
redemptions due to death or disability of the shareholder
shares sold as part of a systematic withdrawal plan as described in this prospectus or the SAI
redemptions made in connection with a return of excess contributions from an IRA account
shares purchased through a Right of Reinstatement (as defined above)
redemptions made as part of a required minimum distribution for IRA and retirement accounts pursuant to the Internal Revenue Code
EDWARD JONES
The following information is provided by Edward D. Jones & Co., L.P. (“Edward Jones”):
Policies Regarding Transactions Through Edward Jones
Effective on or after January 1, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the same fund family, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.
Breakpoints
Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.
Rights of Accumulation (“ROA”)
The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.
The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.
ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).
Letter of Intent (“LOI”)
Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.
If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.
98 | Janus Investment Fund

Sales Charge Waivers
Sales charges are waived for the following shareholders and in the following situations:
Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate.

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.
Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.
Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.
Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions.
Purchases of Class 529 shares made for recontribution of refunded amounts.

The death or disability of the shareholder.

Rights of accumulation which entitle shareholders to breakpoint discounts will be automatically calculated based on the aggregated holding of fund family assets held by accounts within the purchaser’s household at Raymond James. Eligible fund family assets not held at Raymond James may be included in the calculation of rights of accumulation only if the shareholder notifies his or her financial advisor about such assets.
Letters of intent which allow for breakpoint discounts based on anticipated purchases within a fund family, over a 13-month time period. Eligible fund family assets not held at Raymond James may be included in the calculation of letters of intent only if the shareholder notifies his or her financial advisor about such assets.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
104 | Janus Investment Fund

Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form.
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.

Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
1 Year
3 Years
5 Years
10 Years
Class L Shares
$113
$353
$612
$1,352
Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 36% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing primarily in the common stocks of small companies and focuses on companies whose stock prices are believed to be undervalued by the Fund’s portfolio management or that have fallen out of favor with the market. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of small companies whose market capitalization, at the time of initial purchase, is less than the 12-month average of the maximum market capitalization for companies included in the Russell 2000® Value Index. The market capitalizations within the index will vary, but as of June 30, 2024, they ranged from approximately $3 million to $13.14 billion. The 12-month average of the maximum market capitalization for companies included in the Russell 2000 Value Index for the one-year period ended June 30, 2024 was $8.48 billion. From time to time, the Fund may invest in shares of companies through initial public offerings. The Fund may also invest in foreign securities, as well as in real estate investment trusts (“REITs”) and similar REIT-like entities.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
2 | Janus Henderson Small Cap Value Fund

favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns will vary, and you could lose money. The Fund is designed for long-term investors seeking an equity portfolio, including common stocks. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Value Investing Risk.Because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “value” stocks may perform differently than other types of stocks and from the market as a whole, and can continue to be undervalued by the market for long periods of time. It is also possible that a value stock will never appreciate to the extent expected.
Small-Sized Companies Risk.Investments in securities issued by small-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.
Equity Securities Risk.The Fund’s investments in equity securities creates additional risk as those securities typically have greater price volatility than fixed-income securities and may not perform as expected. In addition, equity securities may decline in value in response to general market and economic conditions, which may reduce the Fund’s returns.
REIT Risk.REITs are subject to certain risks inherent in the direct ownership of real estate, including without limitation, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. In addition, a REIT could fail to qualify for tax-free pass-through of its income under the Internal Revenue Code of 1986, as amended, or fail to maintain its exemption from registration under the Investment Company Act of 1940, as amended, which could produce adverse economic consequences for the REIT and its investors, including the Fund. Dividends received by the Fund from a REIT generally will not constitute qualified dividend income.
3 | Janus Henderson Small Cap Value Fund

Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
Initial Public Offering Risk.The Fund’s purchase of shares issued in an initial public offering (“IPO”) exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. There can be no assurance that the Fund will identify favorable IPO investment opportunities.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Russell 2000 Value Index to the Russell 3000 Index due to regulatory requirements. The Fund retained the Russell 2000 Value Index as a performance benchmark because the Russell 2000 Value Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Russell 3000 Index measures the performance of the largest 3000 U.S. companies.
The Russell 2000 Value Index measures the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values.
After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

Purchase and sale of Fund shares
Minimum Investment Requirements
Class L Shares of the Fund are designed for pension and profit-sharing plans, employee benefit trusts, endowments, foundations and corporations, as well as high net worth individuals and financial intermediaries who are willing to maintain a minimum account balance of $250,000.
Purchases, exchanges, and redemptions can generally be made only through institutional channels, such as financial intermediaries and retirement platforms. You should contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund. Requests must be received in good order by the Fund or its agents (financial intermediary or plan sponsor, if applicable) prior to the close of the trading session of the New York Stock Exchange in order to receive that day’s net asset value. For additional information, refer to “Purchases,” “Exchanges,” and/or “Redemptions” in the Prospectus.
Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services, as well as reimbursement to the Adviser of its out-of-pocket costs for services as administrator. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. The Fund pays an investment advisory fee rate that adjusts up or down by a variable rate of up to 0.15% (assuming constant assets) on a monthly basis based upon the Fund’s performance relative to its benchmark index during a measurement period. This base fee rate, prior to any performance adjustment, is 0.72%. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses”
°
include an administrative fee based on the average daily net assets of Class L Shares for shareholder services provided by Janus Henderson Services US LLC (the “Transfer Agent”), the Fund’s transfer agent. The Transfer Agent has agreed to waive all or a portion of this fee. Such waiver is voluntary and could change or be terminated at any time at the discretion of the Transfer Agent or the Adviser without prior notification to shareholders. Removal of this fee waiver may have a significant impact on Class L Shares’ total expense ratio.
°
include acquired fund fees and expenses, which are indirect expenses the Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. Such amounts are less than 0.01%.
°
may include reimbursement to the Transfer Agent of its out-of-pocket costs for arranging for the provision by third parties of certain servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse the Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus. Because a fee waiver and/or reimbursement will have a positive effect upon a fund’s performance, a fund that pays a performance-based investment advisory fee may experience a performance adjustment that is considered favorable to the Adviser as a result of a fee waiver and/or reimbursement that is in place during the period when the performance adjustment applies.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, the Fund will provide shareholders with at least 60 days’ notice prior to changing the 80% investment policy. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary section, including the types of securities the Fund may invest in when

pursuing its investment objective. This section also describes investment strategies and policies that the Fund may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since the Fund’s composition can change over time. Except for the Fund’s policies with respect to illiquid investments, borrowing, and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if the Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
Portfolio management for the Fund primarily invests in the common stocks of companies and focuses on companies whose stock prices are believed to be undervalued or that have fallen out of favor with the market. Portfolio management looks for companies with strong fundamentals and competent management.
As defensive value managers, portfolio management generally looks for companies with:
strong management teams;
strong and stable balance sheets and solid recurring free cash flows;
attractive relative and absolute valuation ratios or that have underperformed recently;
favorable reward to risk characteristics;
sustainable competitive advantages that are trading at attractive valuations; and
strong long-term prospects.
Portfolio management’s philosophy is to weigh a security’s downside risk before considering its upside potential, which may help provide an element of capital preservation. Portfolio management will generally consider selling a Fund holding if, among other things, the security reaches portfolio management’s price target, if the company has a deterioration of fundamentals such as failing to meet key operating benchmarks, or if portfolio management finds a better investment opportunity. Portfolio management will also consider selling a Fund holding to meet redemptions.
A company may be considered attractively valued when, in the opinion of portfolio management, shares of the company are selling for a price that is below their intrinsic worth (“undervalued”). A company may be undervalued due to market or economic conditions, temporary earnings declines, unfavorable developments affecting the company, or other factors. Such factors may provide buying opportunities at attractive prices compared to historical or market price-earnings ratios, price/free cash flow, book value, or return on equity. Portfolio management believes that buying these securities at a price that is below their intrinsic worth may generate greater returns for the Fund than those obtained by paying premium prices for companies currently in favor in the market.
Cash Position
The Fund may not always stay fully invested. For example, when portfolio management believes that market conditions are unfavorable for investing, or when it is otherwise unable to locate attractive investment opportunities, the Fund’s cash or similar investments may increase. When the Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent the Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
In addition, the Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. The Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, the Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Derivatives
The Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. The Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect
8 | Janus Investment Fund

unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
Emerging Markets
Within the parameters of its specific investment policies, the Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Indexsm.
ESG Integration
As part of the Fund’s investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors may include corporate governance, political governance, executive pay, board structure and diversity, business ethics, corporate reporting, company culture, human capital management and diversity, community relations, human rights, exposure to climate change, biodiversity, and deforestation. Portfolio management focuses on the ESG Factors it considers most likely to have a material impact on the long-term financial performance of the issuer, which includes identifying ESG Factors attributable to a particular region, sector, industry, or issuer. To facilitate its assessment of ESG Factors, portfolio management uses issuer reports, third-party data and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio. Portfolio management may assess the relevance of ESG Factors to its fundamental research process differently across issuers, sectors, regions, and asset classes.
Exchange-Traded Funds
The Fund may invest in exchange-traded funds (“ETFs”) to gain exposure to a particular portion of the market. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of the Fund, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. The Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
The Fund may invest in foreign securities. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. The Fund may at times have significant foreign exposure, including exposure to emerging markets.
Illiquid Investments
The Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
Initial Public Offerings and Secondary Offerings
The Fund may purchase shares issued as part of, or a short period after, a company’s initial public offering (“IPO”), and may at times dispose of those shares shortly after their acquisition. An IPO is the first sale of stock by a private company to the public. IPOs are often issued by smaller, younger companies seeking the capital to expand, but can also be done by large privately-owned companies looking to become publicly traded. The Fund may also purchase shares in offerings made by companies that are publicly traded (“secondary offerings”). Secondary offerings may be made by companies for a number of reasons, including as part of a refinancing, to raise capital for growth, and/or to provide existing shareholders with a way to register and sell restricted shares.

Portfolio Turnover
In general, the Fund intends to purchase securities for long-term investment, although, to a limited extent, the Fund may purchase securities in anticipation of relatively short-term gains. Short-term transactions may also result from liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. The Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of the Fund (including due to shareholder purchases and redemptions), the nature of the Fund’s investments, and the investment style of portfolio management. Changes are normally made in the Fund’s portfolio whenever portfolio management believes such changes are desirable. Portfolio turnover rates are generally not a factor in making buy and sell decisions for the Fund.
Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in the acceleration of taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on the Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Fund’s historical turnover rates.
REITs and Real Estate-Related Securities
The Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Securities Lending
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When the Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, the Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to the Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.

Short Sales
The Fund may invest in short positions through short sales of stocks and structured products, and through derivatives that include swaps, uncovered written calls, and futures. The Fund may also engage in short sales “against the box” and options for hedging purposes. Short sales against the box involve selling short a security that the Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. The Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility.
A short sale is generally a transaction in which the Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the borrowed securities be returned to the lender on short notice, and the Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, a “short squeeze” can occur, which means that the demand is greater than the supply for the stock sold short. If a short squeeze occurs, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, the Fund’s losses are potentially unlimited in a short sale transaction. The Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a fund that does not engage in short sales and may negatively affect the Fund’s performance.
The Fund may enter into a derivatives transaction to obtain short investment exposure to an underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Special Situations
The Fund may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of portfolio management, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and the Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.
Other Types of Investments
Unless otherwise stated within its specific investment policies, the Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Fund. If successful, they may benefit the Fund by earning a return on the Fund’s assets or reducing risk; however, they may not achieve the Fund’s investment objective. These securities and strategies may include:
debt securities (such as bonds, notes, and debentures)
preferred stocks and securities convertible into common stocks or preferred stocks
11 | Janus Investment Fund

indexed/structured securities (such as commercial and residential mortgage- and asset-backed securities)
securities purchased on a when-issued, delayed delivery, or forward commitment basis
equity and fixed-income securities issued in private placement transactions
Risks of the Fund
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Fund. To varying degrees, the Fund may invest in stocks, fixed-income securities, money market instruments or cash/cash equivalents, and derivatives. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, the Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of swaps, futures, and options). The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage.
The Fund may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Fund may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk. There is no guarantee that portfolio management’s use of derivative investments will benefit the Fund. The Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited.
Emerging Markets Risk.Within the parameters of its specific investment policies, the Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. To the extent that the Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and
12 | Janus Investment Fund

listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for the Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. The Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require the Fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
European Investments Risk.Exposure to investments in European countries may expose the Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. The Fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.
Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
13 | Janus Investment Fund

The ETFs in which the Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, the Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because the Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.
Foreign Exposure Risk.Within the parameters of its specific investment policies, the Fund may invest in foreign equity and debt securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because the Fund’s performance may depend on factors other than the performance of a particular company. Such risks include currency risk, foreign market risk, geographic concentration risk, political and economic risk, and regulatory risk due to greater exposure to a particular country or geographic region.
Industry and Sector Risk.Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. The Fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase the Fund’s exposure to industry and sector risk.
Initial Public Offering and Secondary Offering Risk.The Fund’s purchase of shares issued in an IPO exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. Attractive IPOs are often oversubscribed and may not be available to the Fund, or may be available only in very limited quantities. The market for IPO issuers has been volatile, and share prices of newly public companies have fluctuated up and down significantly over short periods of time. There can be no assurance that the Fund will identify favorable IPO investment opportunities. In addition, under certain market conditions, a relatively small number of companies may issue securities in IPOs. Similarly, as the number of funds to which IPO securities are allocated increases, the number of securities issued to any one fund may decrease. In addition, as a fund increases in size, the impact of IPOs on the fund’s performance will generally decrease.
The Fund may purchase shares in secondary offerings. Secondary offerings may expose the Fund to some of the risks of IPOs. Participation in secondary offerings may have a magnified impact on the performance of a fund to the extent that it has a small asset base and the fund may not experience similar performance as its assets grow. Secondary offering shares frequently are volatile in price. As a result, the Fund may hold secondary offering shares for a very short period of time. This may increase the portfolio turnover rate of the Fund and may lead to increased expenses for the Fund, such as commissions and transaction costs. In addition, secondary offering shares can experience an immediate drop in value if the demand for the securities does not continue to support the offering price.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of the Fund’s shares. The Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in the Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares.
Liquidity Risk.The Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, the Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower
14 | Janus Investment Fund

volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities.
Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of portfolio securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s net asset value, may increase brokerage costs, and may result in taxable capital gains.
Market Risk.The value of the Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
REIT and Real Estate-Related Securities Risk.To the extent the Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which the Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. The Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.

Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing the return to the Fund on its investment in such company.
Small- and Mid-Sized Companies Risk.The Fund’s investments in securities issued by small- and mid-sized companies, which can include smaller companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, small- and mid-sized companies may suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small- and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger or more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as market conditions change.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the Securities and Exchange Commission (the “SEC”) that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Fund reimburses the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Fund’s Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Fund. The Fund pays these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs expenses, including administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund must pay.
The table below reflects the Fund’s base fee rate (expressed as an annual rate), as well as the actual compensation rate paid by the Fund to the Adviser after any applicable fee waivers and/or expense reimbursements.
The Fund pays an investment advisory fee rate that may adjust up or down based on the Fund’s performance relative to the cumulative investment record of its performance fee benchmark index (referred to in this section as the “benchmark index”), the Russell 2000 Value Index, over a rolling 36-month performance measurement period. The second column in the table below shows the Fund’s base fee rate. The third column shows the full performance rate for outperformance or underperformance during the measurement period relative to the Fund’s benchmark index. The fourth column shows the performance adjusted investment advisory fee rate, which is equal to the Fund’s base fee rate plus or minus the performance
17 | Janus Investment Fund

adjustment over the period without any fee waivers. The fifth column shows the actual compensation rate paid by the Fund after any applicable fee waivers and/or expense reimbursements as of the end of the fiscal year.
As an example, if the Fund outperformed its benchmark index over the performance measurement period by its full performance rate (listed in the table below), the advisory fee would increase by 0.15% (assuming constant assets). Conversely, if the Fund underperformed its benchmark index over the performance measurement period by its full performance rate (listed in the table below), the advisory fee would decrease by 0.15% (assuming constant assets). Actual performance within the full range of the full performance rate may result in positive or negative incremental adjustments to the advisory fee of greater or less than 0.15%. Additional details discussing the performance fee are included below with further description in the SAI.

Due to the restatement of the Fund’s investment advisory fee, the investment advisory fee rates stated above will differ from those in the Fund’s expense table earlier in the Prospectus.
The investment advisory fee rate is determined by calculating a base fee (shown in the previous table) and applying a performance adjustment (described in further detail below). The performance adjustment either increases or decreases the base fee depending on how well the Fund has performed relative to the Russell 2000 Value Index.
The calculation of the performance adjustment applies as follows:
Investment Advisory Fee = Base Fee Rate +/– Performance Adjustment
The investment advisory fee rate paid to the Adviser by the Fund consists of two components: (1) a base fee calculated by applying the contractual fixed rate of the advisory fee to the Fund’s average daily net assets during the previous month (“Base Fee Rate”), plus or minus (2) a performance-fee adjustment (“Performance Adjustment”) calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund’s average daily net assets based on the Fund’s relative performance compared to the cumulative investment record of its benchmark index over a 36-month rolling performance measurement period.
No Performance Adjustment is applied unless the difference between the Fund’s investment performance and the cumulative investment record of the Fund’s benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. The Base Fee Rate is subject to an upward or downward Performance Adjustment for every full 0.50% increment by which the Fund outperforms or underperforms its benchmark index. Because the Performance Adjustment is tied to the Fund’s relative performance compared to its benchmark index (and not its absolute performance), the Performance Adjustment could increase the Adviser’s fee even if the Fund’s Shares lose value during the performance measurement period and could decrease the Adviser’s fee even if the Fund’s Shares increase in value during the performance measurement period. For purposes of computing the Base Fee Rate and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee Rate, versus average daily net assets during the performance measurement period for the Performance Adjustment). Performance of the Fund is calculated net of expenses whereas the Fund’s benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions is included in calculating both the performance of the Fund and the Fund’s benchmark index. The Base Fee Rate is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued throughout the month. The investment advisory fee is paid monthly in arrears. Under extreme circumstances involving underperformance by a rapidly shrinking Fund, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee Rate. In such circumstances, the Adviser would reimburse the Fund.
The application of an expense limit, if any, will have a positive effect upon the Fund’s performance and may result in an increase in the Performance Adjustment. It is possible that the cumulative dollar amount of additional compensation ultimately payable to the Adviser may, under some circumstances, exceed the cumulative dollar amount of management fees waived by the Adviser.
18 | Janus Investment Fund

The investment performance of the Fund’s Class A Shares (waiving the upfront sales load) for the performance measurement period is used to calculate the Performance Adjustment. After the Adviser determines whether the Fund’s performance was above or below its benchmark index by comparing the investment performance of the Fund’s load-waived Class A Shares against the cumulative investment record of the Fund’s benchmark index, the Adviser applies the same Performance Adjustment (positive or negative) across each other class of shares of the Fund, as applicable. It is not possible to predict the effect of the Performance Adjustment on future overall compensation to the Adviser since it depends on the performance of the Fund relative to the record of the Fund’s benchmark index and future changes to the size of the Fund.
A discussion regarding the basis for the Trustees’ approval of the Fund’s investment advisory agreement is included in the Fund’s semiannual report (for the period ended December 31, 2023) and in the Fund’s financial statements (for the period ended June 30, 2024, and moving forward). You can request the Fund’s semiannual reports or financial statements (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus Henderson representative at 1-877-335-2687. This information is also available, free of charge, at janushenderson.com/info.
Expense Limitations
The Adviser has contractually agreed to waive the advisory fee payable by the Fund and/or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding any performance adjustments to management fees, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below. The Adviser has agreed to continue the waiver for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. For information about how the expense limit affects the total expenses of the Fund, if applicable, see the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus.

The Fund pays an investment advisory fee rate that may adjust up or down based on the Fund’s performance relative to its benchmark index during a measurement period. Because a fee waiver and/or reimbursement will have a positive effect upon the Fund’s performance, a fee waiver and/or reimbursement that is in place during the period when the performance adjustment applies may affect the performance adjustment in a way that is favorable to the Adviser.
Portfolio management
Janus Henderson Small Cap Value Fund
Co-Portfolio Managers Craig Kempler and Justin Tugman are responsible for the day-to-day management of the Fund, with no limitation on the authority of one co-portfolio manager in relation to the other.
Craig Kempler, CFA, is Executive Vice President and Co-Portfolio Manager of Janus Henderson Small Cap Value Fund, which he has co-managed since October 2017. He is also Portfolio Manager of other Janus Henderson accounts. Mr. Kempler holds a Bachelor of Arts degree in Economics and Political Science from Denison University and a Master of Business Administration degree in Finance and Accounting from Indiana University. Mr. Kempler holds the Chartered Financial Analyst designation.
Justin Tugman, CFA, is Executive Vice President and Co-Portfolio Manager of Janus Henderson Small Cap Value Fund, which he has co-managed since March 2009. He is also Portfolio Manager of other Janus Henderson accounts. Mr. Tugman holds a Bachelor of Science degree in Finance from the University of Wyoming and a Master of Business Administration degree from Tulane University. He holds the Chartered Financial Analyst designation.
Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund(s) that they manage, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest
19 | Janus Investment Fund

among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that the Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Distribution Schedule
Dividends from net investment income and distributions of net capital gains are normally declared and distributed in December but, if necessary, may be distributed at other times as well. The date you receive your distribution may vary depending on how your intermediary processes trades. Please consult your intermediary for details.
How Distributions Affect the Fund’s NAV
Distributions are paid to shareholders as of the record date of a distribution of the Fund, regardless of how long the Shares have been held. Undistributed dividends and net capital gains are included in the Fund’s daily net asset value (“NAV”). The share price of the Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, the Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of the Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact your financial intermediary. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net
22 | Janus Investment Fund

investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of the Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, the Fund is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary will report cost basis information to you and to the IRS. Your intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The
23 | Janus Investment Fund

Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.
24 | Janus Investment Fund

Shareholder’s guide
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.
The Shares are designed for pension and profit-sharing plans, employee benefit trusts, endowments, foundations and corporations, as well as high net worth individuals and financial intermediaries who are willing to maintain a minimum account balance of $250,000.
Although Class L Shares of the Fund are closed, if you are a current Fund shareholder, you may continue to purchase Shares of the Fund through your existing Fund accounts and to reinvest dividends and capital gains in such accounts. However, once an account is closed, additional investments will not be accepted.
The Fund may not be available through your financial intermediary or plan sponsor. Contact your financial intermediary or plan sponsor, or refer to your plan documents for instructions on how to purchase, exchange, or redeem shares.
Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by the Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
All purchases and redemptions will be duly processed at the NAV next calculated after your request is received in good order by the Fund or its agents. In order to receive a day’s price, your order must be received in good order by the Fund or its agents by the close of the trading session of the NYSE. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares.
Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in
25 | Janus Investment Fund

order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of the Fund’s portfolio securities and the reflection of such change in the Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of the Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by the Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used. Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Fund under the arrangements made between your financial intermediary or plan sponsor and its customers. The Fund is not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to selected brokerage firms or other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries.
For Class L Shares, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for these types of services or other services.
26 | Janus Investment Fund

In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
Although Class L Shares of the Fund are closed, if you are a current Fund shareholder, you may continue to purchase Shares of the Fund through your existing Fund accounts and to reinvest dividends and capital gains in such accounts. Contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund, including additional information on minimum initial or subsequent investment requirements. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Fund’s behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Fund or that provide services in connection with investments in the Fund. You should consider such arrangements when evaluating any recommendation of the Fund.
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading. For more information about the Fund’s policy on excessive trading, refer to “Excessive Trading.”
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account,
27 | Janus Investment Fund

you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Minimum Investment Requirements
Class L Shares of the Fund are designed for pension and profit-sharing plans, employee benefit trusts, endowments, foundations and corporations, as well as high net worth individuals and financial intermediaries who are willing to maintain a minimum account balance of $250,000.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
The Fund reserves the right to change the amount of these minimums from time to time or to waive them in whole or in part.
Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Exchanges
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Contact your financial intermediary or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received. The Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
You must meet the minimum investment amount for each fund.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. The Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. The Fund will work with intermediaries to apply the Fund’s exchange limit. However, the Fund may not always have the ability to monitor or enforce the trading activity in such accounts.
28 | Janus Investment Fund

The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Redemptions
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
Remember that Class L Shares of the Fund are closed, therefore, once an account is closed, additional investments will not be accepted. Redemptions, like purchases, may generally be effected only through financial intermediaries. Please contact your financial intermediary or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of the Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by the Fund or its agents. Redemption proceeds will normally be sent within two business days following receipt of the redemption order. The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same
29 | Janus Investment Fund

manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Systematic Withdrawal Plan
You may arrange for periodic redemptions by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
CLOSED FUND POLICIES
Class L Shares of the Fund are closed to new investors. Current investors in Class L Shares may continue to invest in their Fund account, including reinvestment of any dividends or capital gains distributions. However, once an account is closed, additional investments in the Fund will not be accepted. Other share classes offered by the Fund may be available for purchase for investors who meet certain criteria as outlined in the “Shareholder’s Guide” section of the prospectuses for those respective share classes.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Fund is intended for long-term investment purposes, and the Fund will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Fund’s exchange limits or excessive trading policies and procedures may be cancelled or rescinded by the Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Fund is also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Fund monitors for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Fund at all times reserves the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to the Fund.
The Fund’s Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Fund’s excessive trading policies and procedures and may be rejected in whole or in part by the Fund. Transactions accepted by a financial intermediary in violation of the Fund’s excessive trading policies may be cancelled or revoked by the Fund by the next business day following receipt by the Fund.
In an attempt to deter excessive trading in omnibus accounts, the Fund or its agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Fund’s ability to impose such restrictions with respect to accounts traded through
30 | Janus Investment Fund

particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Fund’s excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Fund by a collective investment trust managed by the Adviser; (iv) transactions in the Fund by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Fund’s policies and procedures regarding excessive trading may be modified at any time by the Fund’s Trustees.
Excessive Trading Risks
Excessive trading may present risks to the Fund’s long-term shareholders. Excessive trading into and out of the Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that the Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of the Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by the Fund despite the Fund’s adoption of policies and procedures intended to reduce the Fund’s exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Fund to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Fund may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Fund and its agents. This makes the Fund’s identification of excessive trading transactions in the Fund through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Fund encourages intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Fund cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Fund.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of the Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for the Fund at janushenderson.com/info. A complete schedule of the Fund’s portfolio holdings is also available in the annual and semiannual financial statements included in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. The Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag.
31 | Janus Investment Fund

Other Information.The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom equity securities ranked by performance attribution, including the percentage attribution to Fund performance, average Fund weighting, and other relevant data points, may be provided monthly with a 15-day lag.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s SAI.
Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor is responsible for providing annual and semiannual reports of the Fund. Please contact your financial intermediary or plan sponsor to obtain these reports. The Fund’s fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that the Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that the Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.

Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form.
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. The Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. The Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. The Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. The Fund may purchase or write such options individually or in combination.
Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which the Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
35 | Janus Investment Fund

When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

(1)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.63%. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated exchange traded funds (“ETFs”) in which the Fund invests, less certain operating expenses. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

$78
$395
$735
$1,696
Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 61% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. For purposes of this 80% policy, the term bonds refers to a variety of fixed-income securities and instruments, and includes, but is not limited to, such investments as government notes and bonds, corporate bonds, convertible securities, commercial paper, commercial and residential mortgage-backed securities, asset-backed securities, collateralized loan obligations, fixed rate notes, floating rate securities, and derivatives such as forwards, swap agreements, futures contracts, and options that provide exposure to various fixed-income instruments (“Fixed-Income Instruments”). The Fund may invest a significant portion of its assets in certain types of Fixed-Income Instruments, including
2 | Janus Henderson Absolute Return Income Opportunities Fund

mortgage-backed securities. In pursuing its investment objective, the Fund will have exposure to investments that are economically tied to a number of countries throughout the world.
The Fund employs an “absolute return” strategy, which means that the Fund benchmarks itself to an index of cash instruments, rather than a fixed-income index. In pursuing this strategy, the Fund seeks to achieve positive returns that exceed its performance benchmark index in a variety of market environments. The Fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income, while at the same time seeking to provide low volatility. The Fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed-income market. For example, portfolio management may favor investments in smaller countries or regions that tend to be underrepresented in fixed-income indices that are more heavily focused on the United States or other larger regions globally. Portfolio management uses research which encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models. A position may be sold if it reaches its total return target, if the investment thesis for owning it changes, or to limit potential losses.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund’s average portfolio duration may range from negative two years to plus four years. As of June 30, 2024, the Fund’s average portfolio duration was 1.29 years. The Fund may invest in securities of varying maturities, although the Fund’s average portfolio maturity is generally less than five years. While the Fund primarily invests in investment-grade debt securities, it may invest up to 25% of its assets in high-yield bonds (also known as “junk” bonds). The Fund may invest in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers.
The Fund may invest in foreign debt securities. At times, the Fund may invest a substantial amount of its assets in foreign debt issuers located in a single region. The Fund will normally limit its foreign currency exchange exposure to 15% of its total assets. The Fund may limit its foreign currency exchange exposure by hedging through the use of forward contracts, cross-currency swaps, currency futures, and options. The Fund may invest in cash or cash equivalents such as short-term government bonds, commercial paper, repurchase agreements, and other short-duration fixed-income securities. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
The Fund may invest in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may utilize interest rate futures, interest rate swaps, credit default swaps (both single-name and index), options, swaptions, and currency forwards for various investment purposes, such as to manage or hedge portfolio risk, enhance return, or manage duration. The Fund may engage in short sales of derivatives instruments such as options, futures, and swaps.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
3 | Janus Henderson Absolute Return Income Opportunities Fund

Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Geographic Concentration Risk.To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.
Australia Risk.The Fund’s investment in Australian issuers may subject the Fund to loss in the event of adverse tax, political, economic, regulatory, and other developments that affect Australia and its fixed-income markets, including
4 | Janus Henderson Absolute Return Income Opportunities Fund

fluctuations of Australian currency versus the U.S. dollar. Also, Australia is economically sensitive to environmental events and is located in a part of the world that has historically been prone to natural disasters, such as drought and flooding.
Derivatives Risk.Derivatives, such as swaps, futures, forwards, and options, can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Swap agreements also bear the risk that the Fund will not be able to meet its obligation to the counterparty. The Fund’s investments in interest rate futures in particular entail the risk that portfolio management’s prediction of the direction of interest rates is wrong, and the Fund could incur a loss. If the Fund invests a significant portion of its assets in derivatives, its investment performance could be dependent on securities not directly owned by the Fund. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.
Currency Risk.Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
5 | Janus Henderson Absolute Return Income Opportunities Fund

Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Although the Fund seeks to provide long-term positive returns, market conditions or implementation of the Fund’s investment process may result in losses, and, in such circumstances, the Fund will not meet its investment objective. As such, there can be no assurance of positive “absolute” returns.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information

Effective August 29, 2024, the Fund changed its broad-based securities market index from the FTSE 3-Month U.S. Treasury Bill Index to the Bloomberg U.S. Aggregate Bond Index due to regulatory requirements. The Fund retained the FTSE 3-Month U.S. Treasury Bill Index as a performance benchmark because the FTSE 3-Month U.S. Treasury Bill Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
The FTSE 3-Month U.S. Treasury Bill Index is an unmanaged index designed to represent the average of Treasury bill rates for each of the prior 3 months, adjusted to a bond equivalent basis.
After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding shareholder servicing fees (but excluding out-of-pocket transfer agency/shareholder servicing costs), acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.57% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds or other income-producing debt-related securities from developed countries. The Fund considers “developed countries” to include, but not be limited to, those countries characterized as developed by the MSCI World Indexsm, including the United States, United Kingdom, Canada, Australia, Sweden, Denmark, Japan, Austria, Belgium, Finland, France, Germany, New Zealand, the Netherlands, and Switzerland, or such other countries as portfolio management deems to be developed.
Under normal circumstances, portfolio management intends to invest at least 40% of the Fund’s net assets outside of the United States and in at least three different countries. A security is deemed to originate in a country if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, the country, (ii) a majority of the company’s assets are located in the country, or (iii) a majority of the company’s revenues are derived from the country. The Fund may also invest up to 20% of its net assets in equity and equity-related
8 | Janus Henderson Developed World Bond Fund

securities such as convertibles and debt securities with warrants. While the Fund has no policy limiting the currency in which foreign securities may be denominated, the Fund seeks to hedge its non-dollar investments back to the U.S. dollar.
Portfolio management uses a process that combines a bottom-up approach to individual security selection rooted in thorough, independent research with a macro-economic overlay that determines appropriate country, asset sector, currency and industry exposure. In their bottom-up approach, portfolio management uses both qualitative and quantitative credit analysis to consider a variety of factors, including the issuer’s experience, managerial strength, debt service capability, operating outlook, sensitivity to economic conditions, current financial condition, liquidity and access to capital, asset protection, structural issues, covenant protection, and equity sponsorship.
Portfolio management meets with prospective and purchased debt issuers. They also work closely with a team of analysts to search for the most appropriate securities to include in the Fund’s portfolio.
Sector, regional and industry allocations are evaluated within a broader economic and market context and involve: (i) evaluation of the economic and interest rate environment that determines asset sector allocation and quality mix; (ii) evaluation of country and regional economic environment to support country allocation decisions; and (iii) analysis of industry weightings, including stability and growth of industries, cash flows and/or positive equity momentum.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG risks and opportunities are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
Portfolio management seeks to (i) avoid corporate issuers that are significantly engaged in business activities that they believe may be environmentally and/or socially harmful, as discussed below; (ii) invest in a portfolio of corporate issuers that, in the aggregate, has a lower carbon intensity and/or footprint than the ICE BofA Global Corporate & High Yield Index on a monthly basis; (iii) avoid sovereign bond issuers that (a) have been sanctioned by the European Union or United Nations or have insufficient rankings with respect to political rights and civil liberties, as measured by third-party inputs, or (b) have not ratified the Paris Climate Accord.
To identify the universe of investible securities for the Fund, portfolio management applies broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that derive more than de minimis revenue from certain activities considered by portfolio management to be environmentally and/or socially harmful. A current list of such business activities, which may evolve over time, follows:
oil and gas generation and production;
oil sands extraction;
shale energy extraction;
thermal coal extraction and power generation;
Arctic oil and gas extraction;
tobacco;
fur;
adult entertainment;
gambling or controversial weapons; and
United Nations Global Compact violators.
The Fund does not apply the avoidance criteria noted above in managing the Fund’s exposure to cash and cash equivalents, U.S. Treasuries, and credit default swaps on indices.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is significant deterioration in company fundamentals, an inability to maintain open communication with management, a change in business strategy, a change in issuer-specific business outlook, realization of anticipated gains, or a failure by the issuer to meet operating/ financial targets. The Fund will also consider selling a security if, in portfolio management’s opinion, it no longer meets the environmental or social criteria noted above, or a superior investment opportunity arises.
9 | Janus Henderson Developed World Bond Fund

Securities in which the Fund may invest include: all types of bonds, debentures, mortgage-related and other asset-backed securities, investment grade debt securities (including corporate debt, developed market government bonds, and U.S. Government securities), high yield securities (also known as “junk” bonds), foreign securities, subordinated bank debt, collective investment schemes, domestic or foreign floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. Portfolio management may shift the Fund’s assets among various types of income-producing securities based upon changing market conditions. The Fund’s average portfolio duration normally may range from zero to plus nine years. Portfolio management may lengthen or shorten the Fund’s duration based on their outlook on interest rates and inflation. The Fund may invest in issuers of any credit quality. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
The Fund may engage in exchange-traded or over-the-counter derivative transactions to seek return, to generate income, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to change the effective duration of the portfolio, to manage certain investment risks, or as a substitute for the purchase or sale of securities or currencies. To the extent derivatives are used, the Fund expects to use them principally when seeking to hedge currency exposure using forward foreign currency contracts, to obtain net long or net negative (short) exposures to selected interest rate, duration or credit risks using a combination of bond or interest rate futures contracts, options on bond or interest rate futures contracts, and interest rate, inflation rate and credit default swap agreements. The Fund may invest in credit default swaps to gain issuer exposure or to gain sector exposure. The Fund may take short positions on derivatives instruments.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and
10 | Janus Henderson Developed World Bond Fund

pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Geographic Concentration Risk.To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.
Europe Risk.The Fund is subject to certain risks associated with Europe and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent. Changes in regulations on trade, decreasing imports or exports, changes in the exchange rate of European currencies, and recessions among European countries may have a significant adverse effect on the economies of other European countries. Western Europe has, in certain instances, been susceptible to serious financial hardship, high debt levels, and high levels of unemployment. The markets in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Industry and Sector Risk.Although the Fund does not concentrate its investments in specific industries, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Companies in the same industry or economic sector may be similarly affected by negative economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
ESG Investment Risk.Because the Fund considers ESG Factors in selecting securities, the Fund may perform differently than funds that do not consider ESG Factors. Due to the ESG considerations and exclusionary criteria employed by the Fund, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. ESG-related information provided by issuers and third parties, which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to consider their environmental or social practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the issuers identified through the investment process employed by the Fund may fail to adhere to positive environmental or social practices, which may result in selling a security when it might otherwise be disadvantageous to do so.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities.
11 | Janus Henderson Developed World Bond Fund

Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on June 5, 2017. The performance shown for Class D Shares for periods prior to June 5, 2017, reflects the performance of Class A Shares of Henderson Strategic Income Fund (the “Predecessor Fund”), calculated using the fees and expenses of Class A Shares of the Predecessor Fund (without sales charges), net of any applicable fee and expense limitations or waivers. The Predecessor Fund was advised by Henderson Global Investors (North America) Inc. and subadvised by Henderson Investment Management Limited. Class A Shares, Class C Shares, Class I Shares, and Class R6 Shares of the Predecessor Fund were reorganized into Class A Shares, Class C Shares, Class I Shares, and Class N Shares, respectively, of the Fund on June 2, 2017. In connection with this reorganization, certain shareholders of the Predecessor Fund who held shares directly with the Predecessor Fund and not
12 | Janus Henderson Developed World Bond Fund

through an intermediary had the Class A Shares, Class C Shares, Class I Shares, and Class N Shares of the Fund received in the merger automatically exchanged for Class D Shares of the Fund following the merger. If Class D Shares of the Fund had been available during periods prior to June 5, 2017, the performance shown may have been different because the Fund and the Predecessor Fund have different expenses. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s (and the Predecessor Fund’s) past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
Effective August 29, 2024, the Fund changed its broad-based securities market index from the Bloomberg Global Aggregate Credit Index (USD Hedged) to the Bloomberg Global Aggregate Bond Index due to regulatory requirements. The Fund retained the Bloomberg Global Aggregate Credit Index (USD Hedged) as a performance benchmark because the Bloomberg Global Aggregate Credit Index (USD Hedged) is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg Global Aggregate Bond Index is a broad-based measure of the global investment grade fixed-rate debt markets.
13 | Janus Henderson Developed World Bond Fund

The Bloomberg Global Aggregate Credit Index (USD Hedged) is the credit component of the Bloomberg Global Aggregate Index, which provides a broad-based measure of the global investment grade fixed income markets. The credit component excludes government bonds and securitized debt.
After-tax returns are calculated using distributions for the Predecessor Fund’s Class A Shares for the period prior to June 5, 2017. If Class D Shares of the Fund had been available during periods prior to June 5, 2017, the distributions used to calculate the after-tax returns may have been different. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses a fund may incur as a result of investing in shares of an underlying fund. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.40%. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated exchange traded funds (“ETFs”) in which the Fund invests, less certain operating expenses. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 170% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by primarily investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. Bonds include, but are not limited to, government notes and bonds, corporate bonds, commercial and residential mortgage-backed securities, asset-backed securities, credit risk transfer securities (“CRTs”), and money market instruments. The Fund may invest in fixed and floating rate obligations with varying durations.
15 | Janus Henderson Flexible Bond Fund

The Fund’s average portfolio duration typically ranges between three and seven years. As of June 30, 2024, the Fund’s average portfolio duration was 6.43 years.
The Fund will invest at least 65% of its net assets in investment grade debt securities. The Fund will limit its investment in high-yield bonds (also known as “junk” bonds) to 35% or less of its net assets. The Fund generates total return from a combination of current income and capital appreciation, but income is usually the dominant portion. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The Fund also invests in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities. The Fund may also invest in foreign securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may use interest rate swaps and futures, including Treasury bond futures, to manage interest rate risk, yield curve positioning, and country exposure. The Fund may also use index credit default swaps for hedging purposes (to offset risks associated with an investment exposure, or market conditions), to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund relative to its benchmark index, and to earn income, enhance returns, or preserve capital. The Fund’s exposure to derivatives will vary. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The Fund may take short positions on derivatives instruments.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
16 | Janus Henderson Flexible Bond Fund

Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Credit Risk Transfer Securities Risk.CRTs are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored enterprises or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. These risks are in addition to the risks described under “Fixed-Income Securities Risk.”
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the
17 | Janus Henderson Flexible Bond Fund

secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders in a taxable account.
TBA Commitments Risk.Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

The Fund’s broad-based benchmark index is the Bloomberg U.S. Aggregate Bond Index. The index is described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may

have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.63% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter.

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 87% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield securities rated below investment grade (also known as “junk” bonds). Securities rated below investment grade may include their unrated equivalents or other high-yielding securities portfolio management believes offer attractive risk/return characteristics. The Fund may at times invest all of its assets in such securities. The Fund may also invest in money market instruments and foreign debt securities. The Fund may also invest in floating rate obligations, such as collateralized loan obligations, floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. The
21 | Janus Henderson High-Yield Fund

Fund’s exposure to derivatives will vary. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. In particular, the Fund may invest in swaps, including index credit default swaps, to increase or decrease the Fund’s exposure to a particular market.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors.

ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult.
22 | Janus Henderson High-Yield Fund

Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. To the extent the Fund invests in foreign debt securities, such investments are sensitive to changes in interest rates. Additionally, investments in securities of foreign governments involve the risk that a foreign government may not be willing or able to pay interest or repay principal when due.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.

Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.

24 | Janus Henderson High-Yield Fund

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Bloomberg U.S. Corporate High-Yield Bond Index to the Bloomberg U.S. Aggregate Bond Index due to regulatory requirements. The Fund retained the Bloomberg U.S. Corporate High-Yield Bond Index as a performance benchmark because the Bloomberg U.S. Corporate High-Yield Bond Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
The Bloomberg U.S. Corporate High-Yield Bond Index is composed of fixed-rate, publicly issued, non-investment grade debt.
After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses a fund may incur as a result of investing in shares of an underlying fund. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(3)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.64%. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated exchange traded funds (“ETFs”) in which the Fund invests, less certain operating expenses. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by primarily investing, under normal circumstances, in a multi-sector portfolio of U.S. and non-U.S. debt securities of varying maturities that portfolio management believes have high income potential relative to other fixed-income instruments available at a given point in time. Portfolio management may also consider the capital
27 | Janus Henderson Multi-Sector Income Fund

appreciation potential of certain investments. The Fund’s investment sectors include, but are not limited to: (i) government notes and bonds; (ii) corporate bonds, including high-yield bonds (also known as “junk” bonds); (iii) commercial loans; (iv) agency and non-agency commercial and residential mortgage-backed securities; (v) asset-backed securities; (vi) convertible securities and preferred stock; and (vii) emerging market debt. Portfolio management believes that by investing in multiple sectors that potentially have low correlation to each other, the Fund’s overall volatility may be reduced. The Fund may not have exposure to all of these investment sectors, and the Fund’s exposure to any one investment sector will vary over time. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.
The Fund’s investments in below investment grade securities are limited to 65% of its net assets, but under unusual circumstances, such as when new issue allocations are higher than expected, this limit may be exceeded on a temporary basis.
The Fund may invest up to 50% of its total assets in the commercial loans sector. Such investments may include bank loans, bridge loans, debtor-in-possession (“DIP”) loans, mezzanine loans, and other fixed and floating rate loans. Normally, the Fund’s exposure to the commercial loans sector will be approximately 15% of the Fund’s total assets. The Fund may invest in floating rate obligations, including collateralized loan obligations, credit risk transfer securities (“CRTs”), floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The Fund may also invest in zero-coupon bonds. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may use swaps, including index credit default swaps, commercial mortgage-backed securities index swaps, and single-name credit default swaps, forward currency exchange contracts, interest rate futures, and put and call options. The Fund may use derivatives for various investment purposes including for hedging purposes, such as to manage portfolio risk or currency risk, to enhance returns, or manage duration. The Fund’s exposure to derivatives will vary. The Fund may engage in short sales of derivatives instruments.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and
28 | Janus Henderson Multi-Sector Income Fund

pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Loan Risk.Bank loans are obligations of companies or other entities sometimes entered into in connection with recapitalizations, acquisitions, and refinancings. The Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged. Loans are subject to credit risk, interest rate risk, and liquidity risk. Investments in certain commercial loans, such as bridge loads, DIP loans, and mezzanine loans subject the Fund to other risks. Bridge loans involve certain risks in addition to those associated with bank loans, including the risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets. Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
29 | Janus Henderson Multi-Sector Income Fund

Credit Risk Transfer Securities Risk.CRTs are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored enterprises or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. These risks are in addition to the risks described under “Fixed-Income Securities Risk.”
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
TBA Commitments Risk.Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets.
Currency Risk.Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. In addition, to the extent that the Fund uses forward currency exchange contracts, there is a risk that unanticipated changes in currency prices may negatively impact the Fund’s performance, among other things. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
30 | Janus Henderson Multi-Sector Income Fund

Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders in a taxable account.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Collateralized Loan Obligation Risk.The risks of investing in collateralized loan obligations (“CLO”) include both the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which the Fund is invested. Higher rated tranches (such as AAA rated tranches) do not constitute a guarantee, may be downgraded, and in stressed market environments it is possible that even senior CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. The Fund’s portfolio management may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are liquidity risk, interest rate risk, credit risk, prepayment risk, and the risk of default of the underlying asset, among others.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and
31 | Janus Henderson Multi-Sector Income Fund

third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.39%. In addition, the Adviser shall reimburse or waive out-of-pocket transfer agency/shareholder servicing costs, payable by any share class so that such fees do not exceed 0.06% of a share class’ average daily net assets. These contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 105% of the average value of its portfolio.
Principal investment strategies
The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in short- and intermediate-term securities such as corporate bonds or notes or government securities, including agency securities, commercial and residential mortgage-backed securities, and asset-backed securities. The Fund may invest in fixed and floating rate obligations with varying durations and credit risk transfer securities (“CRTs”). The Fund will invest at least 65% of its net assets in investment grade debt securities. The Fund may invest up to 35% of its net assets in high-yield bonds (also known as “junk” bonds). The Fund’s investments in short-term securities may include money market instruments. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities, and may also invest in inflation-linked securities, including Treasury Inflation-Protected Securities, also known as TIPS. The Fund may also invest in securities that have contractual restrictions that prohibit or limit
34 | Janus Henderson Short Duration Flexible Bond Fund

their public resale, which may include Rule 144A securities. The Fund may also invest in foreign securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.
The Fund’s average portfolio duration typically ranges between one and three years. As of June 30, 2024, the Fund’s average portfolio duration was 2.03 years.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may use futures, including Treasury bond futures and interest rate swaps, to manage interest rate risk, yield curve positioning, and country exposure. The Fund may also use index credit default swaps for hedging purposes (to offset risks associated with an investment exposure, or market conditions), to increase or decrease the Fund’s exposure to a particular market, and to earn income, enhance returns, or preserve capital. The Fund’s exposure to derivatives will vary. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The Fund may engage in short sales of derivatives instruments.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
35 | Janus Henderson Short Duration Flexible Bond Fund

Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Credit Risk Transfer Securities Risk.CRTs are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored enterprises or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. These risks are in addition to the risks described under “Fixed-Income Securities Risk.”
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the
36 | Janus Henderson Short Duration Flexible Bond Fund

secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
TBA Commitments Risk.Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Inflation-Linked Investments Risk.Inflation-linked bonds (including TIPS), and other inflation-linked securities are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of these securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. The value of inflation-linked securities tends to react to changes in real interest rates. In general, the price of these securities can fall when real interest rates rise, and can rise when real interest rates fall. Interest payments on these securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders in a taxable account.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the
37 | Janus Henderson Short Duration Flexible Bond Fund

collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

If the Fund incurs a loss, which generates a tax benefit, the Return After Taxes on Distributions and Sale of Fund Shares may exceed the Fund’s other return figures.
Effective August 29, 2024, the Fund changed its broad-based securities market index from the Bloomberg 1-3 Year U.S. Government/Credit Index to the Bloomberg U.S. Aggregate Bond Index due to regulatory requirements. The Fund retained the Bloomberg 1-3 Year U.S. Government/Credit Index as a performance benchmark because the Bloomberg 1-3 Year U.S. Government/Credit Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
The Bloomberg 1-3 Year U.S. Government/Credit Index is composed of all bonds of investment grade with a maturity between one and three years.
After-tax returns are calculated using distributions for the Fund’s Class D Shares for the periods following February 16, 2010; and for the Fund’s Class J Shares, the predecessor share class, for periods prior to February 16, 2010. If Class D Shares of the Fund had been available during these earlier periods, distributions may have been different and thus, after-tax returns may have been different from those shown. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

Additional information about the Funds
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services, as well as reimbursement to the Adviser of its out-of-pocket costs for services as administrator. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by each Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses”
°
include an administrative services fee based on the average daily net assets of Class D Shares for shareholder services provided by Janus Henderson Services US LLC (the “Transfer Agent”), the Funds’ transfer agent, as detailed below.

°
include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that a Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights table because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01%, and are included in the Fund’s “Other Expenses.”
°
may include reimbursement to the Transfer Agent of its out-of-pocket costs for arranging for the provision by third parties of certain servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse each Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus.
All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. To the extent that a Fund has an 80% investment policy, the Fund will provide shareholders with at least 60 days’ notice prior to changing this policy. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary sections, including the types of securities each Fund may invest in when pursuing its investment objective. This section also describes investment strategies and policies that the Funds may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since a Fund’s
41 | Janus Investment Fund

composition can change over time. Except for the Funds’ policies with respect to illiquid investments, borrowing, and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
Janus Henderson Absolute Return Income Opportunities Fund employs an “absolute return” strategy, which means that the Fund benchmarks itself to an index of cash instruments, rather than a fixed-income index. In pursuing this strategy, the Fund seeks to achieve positive returns that exceed its performance benchmark index in a variety of market environments. The Fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income, while at the same time seeking to provide low volatility. The Fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed-income market. For example, portfolio management may favor investments in smaller countries or regions that tend to be underrepresented in fixed-income indices that are more heavily focused on the United States or other larger regions globally. Portfolio management uses research which encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models. A position may be sold if it reaches its total return target, if the investment thesis for owning it changes, or to limit potential losses.
Portfolio management for Janus Henderson Developed World Bond Fund uses a process that combines a bottom-up approach to individual security selection rooted in thorough, independent research with a macro-economic overlay that determines appropriate country, asset sector, currency and industry exposure. In their bottom-up approach, portfolio management uses both qualitative and quantitative credit analysis to consider a variety of factors, including the issuer’s experience, managerial strength, debt service capability, operating outlook, sensitivity to economic conditions, current financial condition, liquidity and access to capital, asset protection, structural issues, covenant protection, and equity sponsorship. Portfolio management also works closely with a team of analysts to search for the most appropriate securities to include in the Fund’s portfolio.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is significant deterioration in company fundamentals, an inability to maintain open communication with management, a change in business strategy, a change in issuer-specific business outlook, realization of anticipated gains, or a failure by the issuer to meet operating/ financial targets. The Fund will also consider selling a security if, in portfolio management’s opinion, it no longer meets the environmental or social criteria noted above, or a superior investment opportunity arises.
Portfolio management’s investment process for Janus Henderson Flexible Bond Fund, Janus Henderson High-Yield Fund, Janus Henderson Multi-Sector Income Fund, and Janus Henderson Short Duration Flexible Bond Fund is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
Unless the investment objective or policies prescribe otherwise, portfolio management may consider selling a security when, in portfolio management’s opinion, there is significant deterioration in company fundamentals, an inability to maintain open communication with management, a change in business strategy, a change in issuer-specific business outlook, realization of anticipated gains, or a failure by the issuer to meet operating/financial targets. A Fund may also consider selling a security if, in portfolio management’s opinion, a superior investment opportunity arises.
Cash Position
The Funds may not always stay fully invested. For example, when portfolio management believes that market conditions are unfavorable for investing, or when it is otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. Due to differing investment strategies, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain
42 | Janus Investment Fund

securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Commodity Futures Trading Commission (“CFTC”) Regulation
The operation of Janus Henderson Absolute Return Income Opportunities Fund is subject to certain CFTC rules and regulations. Existing or new CFTC regulation may increase the costs of implementing the Fund’s strategies, which could negatively affect the Fund’s returns.
Derivatives
A Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. A Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
Emerging Markets
Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Indexsm. For Janus Henderson Flexible Bond Fund and Janus Henderson Multi-Sector Income Fund, such countries consist of countries included in the International Monetary Fund list of Emerging and Developing Economies and/or any country that is included in the MSCI Emerging Markets Index, which measures the equity market performance of developing markets. Emerging market countries in which a Fund may invest include frontier market countries, the economies of which are less developed than other emerging market countries. Frontier market countries typically are located in the Asia-Pacific region, Central and Eastern Europe, the Middle East, Central and South America, and Africa.
ESG Investments and Integration
As part of a Fund’s investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors may include corporate governance, political governance, executive pay, board structure and diversity, business ethics, corporate reporting, company culture, human capital management and diversity, community relations, human rights, exposure to climate change, biodiversity, and deforestation. Portfolio management focuses on the ESG Factors it considers most likely to have a material impact on the long-term financial performance of the issuer, which includes identifying ESG Factors attributable to a particular region, sector, industry, or issuer. To facilitate its assessment of ESG Factors, portfolio management uses issuer reports, third-party data and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio. Portfolio management may assess the relevance of ESG Factors to its fundamental research process differently across issuers, sectors, regions, and asset classes.
Portfolio management of Janus Henderson Developed World Bond Fund also seeks to (i) avoid corporate issuers that are significantly engaged in business activities that they believe may be environmentally and/or socially harmful, as discussed below; (ii) invest in a portfolio of corporate issuers that, in the aggregate, has a lower carbon intensity and/or footprint than the ICE BofA Global Corporate & High Yield Index on a monthly basis; (iii) avoid sovereign bond issuers that (a) have been sanctioned by the European Union or United Nations or have insufficient rankings with respect to political rights and civil liberties, as measured by third-party inputs, or (b) have not ratified the Paris Climate Accord.
Additionally, portfolio management applies broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that derive more than de minimis revenue from certain activities considered by portfolio
43 | Janus Investment Fund

management to be environmentally and/or socially harmful. A current list of such business activities, which may evolve over time, follows:
oil and gas generation and production;
oil sands extraction;
shale energy extraction;
thermal coal extraction and power generation;
Arctic oil and gas extraction;
tobacco;
fur;
adult entertainment;
gambling or controversial weapons; and
United Nations Global Compact violators.
The Fund does not apply the avoidance criteria noted above in managing the Fund’s exposure to cash and cash equivalents, U.S. Treasuries, and credit default swaps on indices.
Eurodollar Futures Contracts
Certain Funds may make investments in Eurodollar futures contracts, which are typically used to adjust interest rate exposure and replicate government bond positions. Eurodollar futures contracts are U.S. dollar-denominated futures contracts that are based on a reference rate. Eurodollar futures contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings.
Exchange-Traded Funds
Certain Funds may invest in exchange-traded funds (“ETFs”), including affiliated ETFs, to gain exposure to a particular portion of the market. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of a Fund, which will be indirectly paid by such Fund. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. A Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
A Fund may invest in foreign securities and/or foreign currencies. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. The Funds may at times have significant foreign exposure, including exposure to emerging markets.
High-Yield Bonds
Within the parameters of their specific investment policies, certain Funds may invest in bonds that are rated below investment grade (also known as “junk” bonds), such as BB+ or lower by Standard & Poor’s Ratings Services (“Standard & Poor’s”) and Fitch, Inc. (“Fitch”), or Ba1 or lower by Moody’s Investors Service, Inc. (“Moody’s”), or is an unrated bond of similar quality. A Fund may also invest in unrated bonds of foreign and domestic issuers.
Illiquid Investments
A Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
Inflation-Linked Securities
Certain Funds may invest in inflation-linked securities, including Treasury Inflation-Protected Securities (also known as TIPS), municipal inflation-indexed bonds and corporate inflation-indexed bonds, or in derivatives that are linked to these securities.
44 | Janus Investment Fund

TIPS are inflation-linked bonds issued by the U.S. Government. Inflation-linked bonds may also be issued by, or related to, sovereign governments of other developed countries, emerging market countries, or companies or other entities not affiliated with governments.
Inflation-linked bonds are fixed-income securities whose interest and principal payments are periodically adjusted according to the rate of inflation. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the consumer price index. If an index measuring inflation falls, the principal value of inflation-indexed bonds will typically be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Because of their inflation adjustment feature, inflation-linked bonds typically have lower yields than conventional fixed-rate bonds.
Inflation-linked bonds normally decline in price when real interest rates rise. In the event of deflation, when prices decline over time, the principal and income of inflation-linked bonds would likely decline, resulting in losses to a Fund.
In the case of TIPS, repayment of original bond principal upon maturity (as adjusted for inflation) is guaranteed. When TIPS mature, the holder is paid the adjusted principal or original principal, whichever is greater. For inflation-linked bonds that do not provide a similar guarantee, the adjusted principal value or maturity amount of the inflation-linked bond repaid at maturity may be less than the original principal.
Leverage
Certain of a Fund’s investments, including derivatives and short sale transactions, involve the use of leverage. Leverage is investment exposure which exceeds the initial amount invested. Leverage occurs when a Fund increases its assets available for investment using derivatives, short sales, when-issued, delayed delivery, or forward commitment transactions, or other similar transactions. The use of other investment techniques can also create a leveraging effect on a Fund.
Loans
The Funds may invest in various commercial loans, including bank loans, bridge loans, debtor-in-possession (“DIP”) loans, mezzanine loans, and other fixed and floating rate loans. These loans may be acquired through loan participations and assignments or on a when-issued basis.
Bank Loans.Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. A Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities.
Bridge Loans.Bridge loans are short-term loan arrangements typically made by a borrower in anticipation of receiving intermediate-term or long-term permanent financing. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan increases the longer the loan remains outstanding. In addition, bridge loans commonly contain a conversion feature that allows the bridge loan investor to convert its loan interest to senior exchange notes if the loan has not been prepaid in full on or prior to its maturity date. Bridge loans typically are structured as senior loans, but may be structured as junior loans.
DIP Loans.DIP loans are issued in connection with restructuring and refinancing transactions. DIP loans are loans to a debtor-in-possession in a proceeding under the U.S. bankruptcy code that have been approved by the bankruptcy court. DIP loans are typically fully secured by a lien on the debtor’s otherwise unencumbered assets or secured by a junior lien on the debtor’s encumbered assets (so long as the loan is fully secured based on the most recent current valuation or appraisal report of the debtor). DIP loans are often required to close with certainty and in a rapid manner to satisfy existing creditors and to enable the issuer to emerge from bankruptcy or to avoid a bankruptcy proceeding.
Mezzanine Loans.Mezzanine loans are a hybrid of debt and equity financing that is typically used to fund the expansion of existing companies. A mezzanine loan is composed of debt capital that gives the lender the right to convert to an ownership or equity interest in the company if the loan is not paid back in time and in full. Mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure.
Mortgage- and Asset-Backed Securities
A Fund may purchase fixed or variable rate commercial or residential mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees
45 | Janus Investment Fund

are backed by the full faith and credit of the U.S. Government, which means that the U.S. Government guarantees that the interest and principal will be paid when due. Fannie Mae and Freddie Mac securities, as well as the securities of other government or government-related entities, are not backed by the full faith and credit of the U.S. Government.
A Fund may also purchase mortgage- and asset-backed securities through single- and multi-seller conduits, collateralized mortgage obligations, collateralized loan obligations, collateralized bond obligations, structured investment vehicles, and other similar securities. Asset-backed securities may be backed by various consumer obligations, including automobile loans, equipment leases, credit card receivables, or other collateral. In the event the underlying loans are not paid, the securities’ issuer could be forced to sell the assets and recognize losses on such assets, which could impact a Fund’s yield and return.
Non-Agency Mortgage-Backed Securities
A Fund may invest in non-agency mortgage-backed securities, which are mortgage-backed securities issued or guaranteed by private issuers.
Options on Futures Contracts
An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges. To the extent a Fund engages in futures contracts on foreign exchanges, such exchanges may not provide the same protection as U.S. exchanges.
Options on Securities and Indices
A Fund may purchase and write put and call options on securities and indices. A put option on a security gives the purchaser of the option the right to sell, and the writer of the option the obligation to buy, the underlying security at any time during the option period. A call option on a security gives the purchaser of the option the right to buy, and the writer of the option the obligation to sell, the underlying security at any time during the option period. The premium paid to the writer is the consideration for undertaking the obligations under the option contract.
Put and call options on indices are similar to options on securities except that options on an index give the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the underlying index is greater than (or less than, in the case of puts) the exercise price of the option. This amount of cash is equal to the difference between the closing price of the index and the exercise price of the option, expressed in dollars multiplied by a specified number. Thus, unlike options on individual securities, all settlements are in cash, and gain or loss depends on price movements in the particular market represented by the index generally, rather than the price movements in individual securities. All options written on indices or securities must be “covered” as required by the Investment Company Act of 1940, as amended.
Options on Swap Contracts
A Fund may enter into options on swap agreements, commonly referred to as “swaptions.” A swaption is a contract that gives a purchaser the right, but not the obligation, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement, at some designated future time on specified terms. Swaptions can be used for a variety of purposes, including to manage a Fund’s overall exposure to changes in interest or foreign currency exchange rates and credit quality; as an efficient means of adjusting a Fund’s exposure to certain markets; in an effort to enhance income or total return or protect the value of portfolio securities; to serve as a cash management tool; and to adjust portfolio duration or credit risk.
Portfolio Turnover
Portfolio turnover rates are generally not a factor in making buy and sell decisions for the Funds. Changes may be made to a Fund’s portfolio, consistent with the Fund’s investment objective and policies, when portfolio management believes such changes are in the best interests of the Fund and its shareholders. Short-term transactions may result from the purchase of a security in anticipation of relatively short-term gains, liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to shareholder purchases and redemptions), the nature of a Fund’s investments, and the investment style of portfolio management. Changes are normally made in a Fund’s portfolio whenever portfolio management believes such changes are desirable. Due to the nature of the securities in which they invest, the Funds may have relatively high portfolio turnover compared to other funds.
46 | Janus Investment Fund

Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in the acceleration of taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
REITs and Real Estate-Related Securities
Each Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Securities Lending
A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. A Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, a Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and a Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If a Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to a Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Short Sales
The Funds may invest in short positions through short sales of stocks and structured products, and through derivatives that include swaps, uncovered written calls, and futures. A Fund may also engage in short sales “against the box” and options for hedging purposes. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility.
A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short
47 | Janus Investment Fund

position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the borrowed securities be returned to the lender on short notice, and the Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, a “short squeeze” can occur, which means that the demand is greater than the supply for the stock sold short. If a short squeeze occurs, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a fund that does not engage in short sales and may negatively affect the Fund’s performance.
A Fund may enter into a derivatives transaction to obtain short investment exposure to an underlying reference asset. If the value of the underlying reference asset on which a Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes a Fund to credit risk, counterparty risk, and leverage risk.
Sovereign Bond Futures Contracts
Sovereign bond futures contracts provide for the delivery upon maturity of one sovereign bond among a basket of eligible-to-deliver sovereign bonds.
Special Situations
The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of portfolio management, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.
Swap Agreements
Certain Funds may utilize swap agreements including, but not limited to, credit default swaps, equity swaps, inflation index swaps, inflation-linked swaps, interest rate and currency swaps, total return swaps (including fixed-income total return swaps), and swaps on exchange-traded funds, as a means to gain exposure to certain companies or countries, a commodity index, or commodity markets, and/or to “hedge” or protect their portfolios from adverse movements in securities prices, the rate of inflation, or interest rates. Swaps may also be used for capital appreciation. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to a Fund. If the other party to a swap defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly, the swap may result in a loss to the Fund and reduce the Fund’s total return. Various types of swaps such as credit default, equity, interest rate, currency, inflation index, and total return are described in this Prospectus and/or in the “Glossary of Investment Terms.”
Cross-Currency Swaps.Certain Funds may enter into cross-currency swaps or basis swaps. A cross-currency swap involves the exchange of payments denominated in one currency for payments denominated in another. Payments are based on a notional principal amount, the value of which is fixed in exchange rate terms at the swap’s inception.
Index Credit Default Swaps.Certain Funds may invest in index credit default swaps (“CDX”). CDX are swaps on an index of credit default swaps. CDX allow an investor to manage credit risk or take a position on a basket of credit entities (such as
48 | Janus Investment Fund

credit default swaps or a commercial mortgage-backed index) in a more efficient manner than transacting in a single-name credit default swap. If a credit event occurs in one of the underlying companies, the protection is paid out via the delivery of the defaulted bond by the buyer of protection in return for a payment of notional value of the defaulted bond by the seller of protection or it may be settled through a cash settlement between the two parties. The underlying company is then removed from the index. New series of CDX are issued on a regular basis.
Commercial mortgage-backed securities index swaps (“CMBX”) are a type of index credit default swap that are made up of tranches of commercial mortgage-backed securities rather than credit default swaps. CMBX involve a pay-as-you go settlement process designed to capture non-default events that affect the cash flow to the underlying mortgage-backed securities tranche.
Interest Rate Swaps.Certain Funds may enter into interest rate swaps, which involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments). Interest rate swaps are generally entered into on a net basis. Interest rate swaps do not involve the delivery of securities, other underlying assets, or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that certain Funds are contractually obligated to make.
Single-Name Credit Default Swaps.A Fund may invest in single-name credit default swaps (“CDS”) to buy or sell credit protection to hedge its credit exposure, gain issuer exposure without owning the underlying security, or increase the Fund’s total return. CDS are a specific kind of counterparty agreement that allow the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the CDS agrees to insure this risk in exchange for regular periodic payments.
TBA Commitments
A Fund may enter into “to be announced” or “TBA” commitments. TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining a Fund’s net asset value. Because a Fund is generally not required to pay for the security until the settlement date, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
Treasury Futures Contracts
Treasury futures contracts, which are exchange-traded, are typically used to obtain interest rate exposure in order to manage duration. A Treasury futures contract is a bilateral agreement where one party agrees to accept and the other party agrees to make delivery of a U.S. Treasury security, as called for in the agreement at a specified date and at an agreed upon price. Generally, Treasury futures contracts are closed out or rolled over prior to their expiration date.
U.S. Government Securities
The Funds may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer. For securities not backed by the full faith and credit of the United States, a Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets.
Other Types of Investments
Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal
49 | Janus Investment Fund

investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:
equity securities (such as stocks or any other security representing an ownership interest)
preferred stocks and securities convertible into common stocks or preferred stocks
pass-through securities including commercial and residential mortgage- and asset-backed securities and mortgage dollar rolls
zero coupon, pay-in-kind, and step coupon securities
securities purchased on a when-issued, delayed delivery, or forward commitment basis
equity and fixed-income securities issued in private placement transactions
Risks of the Funds
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The Funds invest substantially all of their assets in fixed-income securities or income-generating securities and, to varying degrees, derivatives. The following information is intended to help you better understand some of the risks of investing in the Funds, including those risks that are summarized in the Fund Summary sections. This information also includes descriptions of other risks a Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Collateralized Loan Obligation Risk.The risks of investing in a collateralized loan obligation (“CLO”) can be generally summarized as a combination of economic risks of the underlying loans and the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which a Fund is invested. Higher rated tranches (such as AAA rated tranches) do not constitute a guarantee and in stressed market environments it is possible that these CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. A Fund’s portfolio management may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are interest rate risk, credit risk, liquidity risk, prepayment risk, and the risk of default of the underlying asset, among others.
Collateralized Mortgage Obligation Risk.Collateralized mortgage obligations (“CMOs”) are a type of mortgage-backed security. CMOs are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams (tranches) with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches may represent a right to receive interest only (“IOs”), principal only (“POs”) or an amount that remains after floating-rate tranches are paid (an inverse floater). These securities are frequently referred to as “mortgage derivatives” and may be extremely sensitive to changes in interest rates. Interest rates on inverse floaters, for example, vary inversely with a short-term floating rate (which may be reset periodically). Interest rates on inverse floaters will decrease when short-term rates increase, and will increase when short-term rates decrease. These securities have the effect of providing a degree of investment leverage. In response to changes in market interest rates or other market conditions, the value of an inverse floater may increase or decrease at a multiple of the increase or decrease in the value of the underlying securities. If a Fund invests in CMO tranches (including CMO tranches issued by government agencies) and interest rates move in a manner not anticipated by the Adviser, it is possible that the Fund could lose all or substantially all of its investment.
Convertible Securities Risk.A Fund may invest in securities that are convertible into preferred and common stocks, and thus, is subject to the risks of investments in both debt and equity securities. The market value of convertible securities tends to decline as interest rates increase and, conversely, tends to increase as interest rates decline. In addition, because of the conversion feature, the market value of convertible securities tends to vary with fluctuations in the market value of the underlying preferred and common stocks and, therefore, also will react to variations in the general market for equity securities.
50 | Janus Investment Fund

Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, a Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of forwards, swaps, futures, and options). Each Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.Through a Fund’s investments in fixed-income securities, a Fund is subject to the risks associated with the credit quality of the issuers of those fixed-income securities. Credit quality measures the likelihood that the issuer or borrower will meet its obligations on a bond. One of the fundamental risks is credit risk, which is the risk that an issuer will be unable to make principal and interest payments when due, or default on its obligations. Higher credit risk may negatively impact a Fund’s returns and yield.
Many fixed-income securities receive credit ratings from services such as Standard & Poor’s, Fitch, and Moody’s. These services assign ratings to securities by assessing the likelihood of issuer default. The lower a bond issue is rated by an agency, the more credit risk it is considered to represent. Lower rated instruments and securities generally pay interest at a higher rate to compensate for the associated greater risk. Interest rates can fluctuate in response to economic or market conditions, which can result in a fluctuation in the price of a security and impact a Fund’s return and yield. If a security has not received a rating, a Fund must rely upon the Adviser’s credit assessment, which if incorrect can also impact the Fund’s returns and yield. Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause a Fund to be more volatile than if it had not used leverage.
The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk or may use futures contracts on securities indices to gain exposure to equity securities. There is no guarantee that portfolio management’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.
Cross-Currency Swaps Risk.Cross-currency or basis swaps are subject to currency risk. They also involve exchange risk on principal and are subject to credit risk.
Currency Futures Risk.Currency futures are similar to forward foreign currency exchange contracts, and pose similar risks, except that futures contracts are standardized, exchange-traded contracts while forward foreign currency exchange contracts are traded in the over-the-counter market. The use of currency futures contracts may substantially change a Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as anticipated. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns. Currency futures may also involve leverage risk.
51 | Janus Investment Fund

Eurodollar Futures Contracts Risk.Eurodollar futures contracts involve market risk associated with changes in interest rates.
Forward Foreign Currency Exchange Contract Risk.Forward foreign currency exchange contracts (“forward currency contracts”) involve the risk that unanticipated changes in currency prices may negatively impact a Fund’s performance. Moreover, there may be an imperfect correlation between a Fund’s portfolio holdings of securities quoted or denominated in a particular currency and any forward currency contracts entered into by the Fund, which will expose the Fund to risk of foreign exchange loss. The trading markets for forward currency contracts offer less protection against defaults than trading in currency instruments on an exchange. Because a forward currency contract is not guaranteed by an exchange or clearinghouse, a default on the contract could result in losses to a Fund and may force the Fund to cover its purchase or sale commitments, if any, at the current market price. In addition, forward currency contract markets can experience periods of illiquidity, which could prevent a Fund from divesting of a forward currency contract at the optimal time and may adversely affect a Fund’s returns and net asset value.
Futures and Swaps Related to Interest Rate Risk.A Fund’s investments in interest rate futures, swaps, or futures on interest rate sensitive securities entail the risk that portfolio management’s prediction of the direction of interest rates is wrong, and the Fund could incur a loss. In addition, due to the possibility of price distortions in the interest rate futures or swaps markets, or an imperfect correlation between the underlying instrument and the interest rate portfolio management is seeking to hedge, a correct forecast of general interest rate trends by portfolio management may not result in the successful use of futures and swaps related to interest rates.
Index Credit Default Swaps Risk.If a Fund holds a long position in CDX, the Fund would indirectly bear its proportionate share of any expenses paid by CDX. By investing in CDX, a Fund could be exposed to illiquidity risk, counterparty risk, and credit risk of the issuers of the underlying loan obligations and of the CDX markets. If there is a default by the CDX counterparty, a Fund will have contractual remedies pursuant to the agreements related to the transaction. CDX also bear the risk that a Fund will not be able to meet its obligation to the counterparty.
Options on Futures Contracts Risk.The amount of risk that a Fund assumes when it purchases an option on a futures contract is the premium paid for the option, plus related transaction costs. In order to profit from an option purchased, it may be necessary to exercise the option and to liquidate the underlying futures contract subject to the risks of the availability of a liquid offset market. The seller of an option on a futures contract is subject to the risks of commodity futures trading, including the requirement of initial and variation margin payments, as well as the additional risk that movements in the price of the option may not correlate with movements in the price underlying security, index, currency, or futures contracts.
Options on Securities and Indices Risk.Options on securities may be subject to greater fluctuations in value than an investment in the underlying securities. If a Fund is unable to effect a closing purchase transaction with respect to covered options it has written, the Fund will not be able to sell the underlying securities or dispose of assets held in a segregated account until the options expire or are exercised. Similarly, if the Fund is unable to effect a closing sale transaction with respect to options it has purchased, it will have to exercise the options in order to realize any profit and will incur transaction costs upon the purchase or sale of underlying securities.
Options on indices may, depending on circumstances, involve greater risk than options on securities. Because index options are settled in cash, when a Fund writes a call on an index it may not be able to provide in advance for its potential settlement obligations by acquiring and holding the underlying securities.
Options on Swap Contracts Risk.Because the use of options on swap contracts, or “swaptions,” generally does not involve the delivery of securities or other underlying assets or principal, the risk of loss with respect to swaptions generally is limited to the net amount of payments that a Fund is contractually obligated to make. There is also a risk of a default by the other party to a swaption, in which case the Fund may not receive the net amount of payments that it contractually is entitled to receive. Entering into a swaption contract involves, to varying degrees, the elements of credit, market, and interest rate risk, associated with both option contracts and swap contracts.
Single-Name Credit Default Swaps Risk.When a Fund buys a single-name CDS, the Fund will receive a return on its investment only in the event of a credit event, such as default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). If a single-name CDS transaction is particularly large, or if the relevant market is illiquid, it may not be possible for the Fund to initiate a single-name CDS transaction or to liquidate its
52 | Janus Investment Fund

position at an advantageous time or price, which may result in significant losses. Moreover, the Fund bears the risk of loss of the amount expected to be received under a single-name CDS in the event of the default or bankruptcy of the counterparty. The risks associated with cleared single-name CDS may be lower than that for uncleared single-name CDS because for cleared single-name CDS, the counterparty is a clearinghouse (to the extent such a trading market is available). However, there can be no assurance that a clearinghouse or its members will satisfy their obligations to the Fund. Unlike CDX, single-name CDS do not have the benefit of diversification across many issuers.
Sovereign Bond Futures Contracts Risk.Interest rate movements directly affect the price of the sovereign bond futures contracts held by a Fund. If a sovereign bond futures contract is denominated in a non-U.S. currency, a Fund will be exposed to exchange rate risk. In addition, the price, yield, and modified duration of each eligible-to-deliver sovereign bond under the relevant sovereign bond futures contract may change unpredictably, affecting the value of the sovereign bond futures contract.
Treasury Futures Contracts Risk.While transactions in Treasury futures contracts may reduce certain risks, unanticipated changes in interest rates or securities prices may result in a poorer overall performance for a Fund than if it had not entered into any Treasury futures contracts. To the extent a Fund uses Treasury futures contracts, it is exposed to additional volatility and potential losses resulting from leverage. Losses (or gains) involving Treasury futures contracts can sometimes be substantial – in part because a relatively small price movement in a Treasury futures contract may result in an immediate and substantial loss (or gain) for a Fund.
Emerging Markets Risk.Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. For Janus Henderson Flexible Bond Fund and Janus Henderson Multi-Sector Income Fund, such countries consist of countries included in the International Monetary Fund list of Emerging and Developing Economies and/or any country that is included in the MSCI Emerging Markets Index, which measures the equity market performance of developing markets. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
Emerging market countries in which a Fund may invest include frontier market countries, which generally have smaller economies and even less developed capital markets than traditional developing markets, and as a result, the risks of investing in developing market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by other countries; and the relatively new and unsettled securities laws in many frontier market countries.

ESG Integration and Investment Risk.There is a risk that considering ESG Factors as part of a Fund’s investment process may fail to produce the intended results or that a Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require a Fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
Janus Henderson Developed World Bond Fund may employ exclusionary criteria to avoid investing in certain industries, activities, or assets considered by portfolio management to have a negative impact on society or the environment. This Fund is subject to similar risks as those Funds that consider ESG Factors as part of their investment process.
European Investments Risk.Exposure to investments in European countries may expose a Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. A Fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.
Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When a Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, a Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which a Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, a Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because a Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk. To the extent a Fund invests in fixed-income ETFs, it will be indirectly exposed to the same risks described under “Fixed-Income Securities Risk.”
Exchange-Traded Notes Risk.Exchange-traded notes (“ETNs”) are debt securities whose returns are linked to a particular index. ETNs are typically linked to the performance of a commodities index that reflects the potential return on unleveraged investments in futures contracts of physical commodities, plus a specified rate of interest that could be earned on cash collateral. ETNs are subject to credit risk and counterparty risk. The value of an ETN may vary and may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events that affect the referenced commodity. When a Fund invests in ETNs it will bear its proportionate share of any fees and expenses borne by the ETN. There may be restrictions on a Fund’s right to redeem its investment in an ETN, which is meant to be held until maturity. A Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market.
54 | Janus Investment Fund

Fixed-Income Securities Risk.Each Fund invests in a variety of fixed-income securities. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that the value of such securities will generally decline as prevailing interest rates rise, which may cause a Fund’s net asset value to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities and durations tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates and are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. However, calculations of maturity and duration may be based on estimates and may not reliably predict a security’s price sensitivity to changes in interest rates. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. Investments in fixed-income securities with very low or negative interest rates may diminish a Fund’s yield and performance.
Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. In addition, there is prepayment risk, which is the risk that during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause a Fund to reinvest its assets in securities with lower yields, resulting in a decline in a Fund’s income or return potential. Fixed-income securities may also be subject to valuation risk and liquidity risk. Valuation risk is the risk that one or more of the fixed-income securities in which a Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer of the security. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk. To the extent a Fund invests in fixed-income securities in a particular industry or economic sector, its share values may fluctuate in response to events affecting that industry or sector. Securities underlying mortgage- and asset-backed securities, which may include subprime mortgages, also may be subject to a higher degree of credit risk, valuation risk, and liquidity risk. To the extent that a Fund invests in derivatives tied to fixed-income securities, the Fund may be more substantially exposed to these risks than a fund that does not invest in such derivatives. The market for certain fixed-income securities may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Similarly, the amount of assets deemed illiquid remaining within a Fund may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the Fund.
Foreign Exposure Risk.Within the parameters of its specific investment policies, each Fund may invest in foreign debt and equity securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:
Currency Risk.As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Foreign Market Risk.Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions.
55 | Janus Investment Fund

Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.
Geographic Concentration Risk.To the extent that a Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.
Political and Economic Risk.Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the U.S. Government on other countries or persons or issuers operating in such countries could restrict a Fund’s ability to buy affected securities or force a Fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, a Fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
Regulatory Risk.There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
Transaction Costs.Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s, Fitch, and Moody’s or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
The secondary market on which high-yield securities are traded is less liquid than the market for investment grade securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. Additionally, it may be more difficult to value the securities because valuation may require more research, and elements of judgment may play a larger role in the valuation because there is less reliable, objective data available.
Because Janus Henderson Developed World Bond Fund, Janus Henderson High-Yield Fund, and Janus Henderson Multi-Sector Income Fund may invest a substantial amount of their net assets in high-yield bonds, investors should be willing to tolerate a corresponding increase in the risk of significant and sudden changes in net asset value.
Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Impairment of Collateral Risk.The value of collateral, if any, securing a floating rate loan can decline, and may be insufficient to meet the borrower’s obligations or difficult to liquidate. In addition, Janus Henderson Developed World Bond
56 | Janus Investment Fund

Fund’s access to collateral may be limited by bankruptcy or other insolvency laws. Further, certain floating rate loans may not be fully collateralized and may decline in value.
Industry and Sector Risk.Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase that Fund’s exposure to industry and sector risk.
Inflation Risk.Inflation risk is the risk that the value of certain assets or real income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the present value of a Fund’s assets and distributions may decline. This risk may be elevated in a low interest rate environment.
Inflation-Linked Investments Risk.Inflation-linked bonds (including TIPS), and other inflation-linked securities normally will decline in price when real interest rates rise. In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, inflation-linked bonds may experience greater losses than other fixed-income securities with similar durations. Except for a Fund’s investments in TIPS, which are guaranteed as to principal by the U.S. Treasury, the inflation-adjusted principal value or maturity amount of inflation-linked bonds repaid at maturity may be less than the original principal. Because of their inflation-linked adjustment feature, inflation-linked bonds typically have lower yields than conventional fixed-rate securities. In the event of deflation, where prices decline over time, the principal and income of inflation-linked bonds will likely decline, resulting in losses to a Fund.
Interest Rate Risk.Generally, a fixed-income security will increase in value when prevailing interest rates fall and decrease in value when prevailing interest rates rise. Longer-term securities are generally more sensitive to interest rate changes than shorter-term securities, but they generally offer higher yields to compensate investors for the associated risks. High-yield bond prices and floating rate debt security prices are generally less directly responsive to interest rate changes than investment grade issues or comparable fixed rate securities, and may not always follow this pattern.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of a Fund’s shares. A Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares.
Leverage Risk.Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose a Fund to greater risk and increase its costs. The use of leverage may cause a Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act of 1940, as amended, and the rules thereunder. Increases and decreases in the value of a Fund’s portfolio will be magnified when the Fund uses leverage.
Liquidity Risk.A Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, a Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, a Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect a Fund’s value or prevent such Fund from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that a Fund invests in restricted securities that are deemed to be illiquid investments.
57 | Janus Investment Fund

Liquidity risk may also refer to the risk that a Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of portfolio securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s net asset value, may increase brokerage costs, and may result in taxable capital gains.
Loan Risk.The Funds may invest in various commercial loans. The risks of such investments vary, depending on the type of loans underlying the investments, as described below.
Bank Loan Risk.The bank loans in which the Funds invest may be denominated in U.S. or non-U.S. currencies, including the euro. Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. A Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged or in bankruptcy proceedings. Participation interests and assignments involve credit, interest rate, and liquidity risk. Some participation interests and assignments may not be considered “securities,” and purchasers, such as a Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Additionally, because the Adviser, in the course of investing a Fund’s assets in loans, may have access to material non-public information regarding the borrower, the ability of the Fund to purchase or sell publicly-traded securities of such borrowers may be restricted. In addition, to the extent a Fund invests in non-U.S. bank loan investments, those investments also are subject to the risks of foreign investment, including those described under “European Investments Risk.”
If a Fund purchases a participation interest, it may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender. There are also risks involved in purchasing assignments. If a loan is foreclosed, a Fund may become part owner of any collateral securing the loan and may bear the costs and liabilities associated with owning and disposing of any collateral. The Fund could be held liable as a co-lender. In addition, there is no assurance that the liquidation of any collateral from a secured loan would satisfy a borrower’s obligations or that any collateral could be liquidated. There may be a number of intermediate participants in bank loan transactions and loan agreements that have specific rights, obligations, terms, and conditions. As such, any number of factors in an investment in bank loans could cause a Fund to lose income or principal on a particular investment, which in turn could affect the Fund’s returns, and you could lose money.
Interest rates on floating rate bank loans adjust with interest rate changes and/or issuer credit quality, and unexpected changes in such rates could result in losses to a Fund. Additionally, borrowers may pay back principal in whole or part, prior to scheduled due dates. Such prepayment may result in a Fund realizing less income on a particular investment and replacing the floating rate bank loan with a less attractive security, which may provide less return to the Fund.
Bank loans are generally less liquid than many other fixed-income securities and may be subject to restrictions on resale. Transactions in bank loans may take more than seven days to settle. As a result, the proceeds related to the sale of bank loans may not be available to make additional investments or to meet a Fund’s redemption obligations until a substantial period after the sale of the loans. To the extent that extended settlement creates short-term liquidity needs, a Fund may satisfy these needs by holding additional cash or selling other investments (potentially at an inopportune time, which could result in losses to the Fund).
A Fund may not be able to identify and invest in attractive floating rate bank loans, such as senior loans, as the market for such investments may be limited in certain economic conditions or because of a high number of potential purchasers of assignments and participations. A Fund may also invest in other floating rate debt securities or other investments. For example, the Fund may invest in junior or subordinated loans or unsecured loans. Such loans may not provide desired returns or may increase the potential for loss of income or principal. Bank loan investments may be generally considered speculative and risks arising from a Fund’s investments in bank loans may be similar to those of investments in “junk” bonds or below investment grade investments. A Fund’s investments in bank loans may be more sensitive to economic changes, political changes, or adverse developments specific to the borrower than higher quality investments.
Bridge Loan Risk.Investments in bridge loans subject a Fund to certain risks in addition to those described above. In addition, any delay in obtaining permanent financing subjects the bridge loan investor to increased risk. A borrower’s use of
58 | Janus Investment Fund

bridge loans also involves the risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness.
DIP Loan Risk.Investments in DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets. In the event of liquidation, a Fund’s only recourse will be against the property securing the DIP loan.
Mezzanine Loan Risk.Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations. Mezzanine loans, which are usually issued in private placement transactions, may be considered illiquid. In addition, they are often used by smaller companies that may be highly leveraged, and in turn may be subject to a higher risk of default. Investment in mezzanine loans is a specialized practice that depends more heavily on independent credit analysis than investments in other fixed-income securities.
Market Risk.The value of a Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Money Market Fund Investment Risk.A Fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, a Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and a Fund may lose money. To the extent a Fund transacts in instruments such as derivatives, such Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from such Fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share net asset value at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable net asset value could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their net asset values. Certain money market funds have in the past failed to maintain stable net asset values, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the Securities and Exchange Commission (the “SEC”) require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s net asset value per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market
59 | Janus Investment Fund

Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating net asset value requirements. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund.
Recently adopted amendments to Rule 2a-7 also require certain money market funds, excluding Government Money Market Funds and Retail Money Market Funds, to impose mandatory liquidity fees when a fund experiences net redemptions that exceed 5% of its net assets, unless the fund’s liquidity costs are de minimis (i.e., less than 1 basis point).
There can be no assurance that a Fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
In addition to the fees and expenses that a Fund directly bears, a Fund indirectly bears the fees and expenses of any money market fund in which it invests.
Mortgage- and Asset-Backed Securities Risk.Rising interest rates tend to extend the duration of, or reduce the rate of prepayments on, both commercial mortgage-backed securities (“CMBS”) and residential mortgage-backed securities (“RMBS”), making them more sensitive to changes in interest rates (“extension risk”). As a result, in a period of rising interest rates, the price of mortgage-backed securities may fall, causing a Fund that holds mortgage-backed securities to exhibit additional volatility. Mortgage-backed securities are also subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce a Fund’s returns because the Fund will have to reinvest that money at lower prevailing interest rates. Investments in certain mortgage-backed securities, including those comprised of subprime mortgages, may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities. Additionally, although mortgage-backed securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that guarantors or insurers will meet their obligations.
CMBS are subject to certain other risks. The market for CMBS developed more recently than that for RMBS and is relatively small in terms of outstanding principal amount of issues compared to the RMBS market. CMBS are also subject to risks associated with a lack of standardized terms, shorter maturities than residential mortgage loans, and payment of all or substantially all of the principal at maturity, rather than regular amortization of principal. Moreover, the type and use of a particular commercial property may add to the risk of CMBS investments. Adverse changes in economic conditions and circumstances are more likely to have an adverse impact on mortgage-backed securities secured by loans on commercial properties than on those secured by residential properties.
Similarly, the value of a Fund’s investments in asset-backed securities may be adversely affected by changes in interest rates, factors concerning the interests in and structure of the issuer or originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds, or other credit or liquidity enhancements, and/or the market’s assessment of the quality of the underlying assets. Generally, the originating bank or credit provider is neither the obligor nor the guarantor of the security, and interest and principal payments ultimately depend upon payment of the underlying loans by individuals. A Fund could incur a loss if the underlying loans are not paid. In addition, most asset-backed securities are subject to prepayment risk in a declining interest rate environment. The impact of prepayments on the value of asset-backed securities may be difficult to predict and may result in greater volatility. Rising interest rates tend to extend the duration of asset-backed securities, making them more volatile and sensitive to changing interest rates.
Newly Issued Securities Risk.The credit obligations in which certain Funds invest may include newly issued securities, or “new issues,” such as initial debt offerings. New issues may not be consistently available to a Fund for investing, particularly as a Fund’s asset base grows. Certain new issues, such as initial debt offerings, may be volatile in price due to the absence of a prior trading market, limited quantities available for trading and limited information about the issuer. A Fund may hold new issues for a short period of time. This may increase a Fund’s portfolio turnover and may lead to increased expenses for the Fund, such as commissions and transaction costs. New issues may have a magnified impact on the performance of a Fund during periods in which it has a small asset base. The impact of new issues on a Fund’s performance likely will decrease as the Fund’s asset size increases, which could reduce the Fund’s returns. In addition, new issues can experience an immediate drop in value after issuance if the demand for the securities does not continue to support the offering price.
60 | Janus Investment Fund

Portfolio Management Risk.The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and research process employed for the Funds may fail to produce the intended results. Accordingly, the Funds may underperform benchmark indices or other funds with similar investment objectives.
Private Placements and Other Exempt Securities Risk.Investments in private placements and other securities exempt from certain registration requirements could decrease a Fund’s liquidity profile or prevent a Fund from disposing of them promptly at advantageous prices. Private placements and other securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. Transaction costs may be higher for these securities, and a Fund may get only limited information about the issuer of a private placement or other security exempt from certain registration requirements.
REIT and Real Estate-Related Securities Risk.To the extent a Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which a Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. A Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing the return to the Fund on its investment in such company.
Sovereign Debt Risk.A Fund may invest in U.S. and non-U.S. government debt securities (“sovereign debt”). Investments in sovereign debt, especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. A Fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the Fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent a Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
61 | Janus Investment Fund

TBA Commitments Risk.A Fund may enter into “to be announced” or “TBA” commitments. Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, a Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to a Fund may be less favorable than expected. There is a risk that the security that a Fund buys will lose value between the purchase and settlement dates. When a Fund sells a TBA security prior to settlement, it does not participate in future gains or losses with respect to the security. A Fund is generally not required to pay for the TBA security until the settlement date and, as a result, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
Warrants and Rights Risk.The price, performance and liquidity of warrants and rights to purchase equity securities are typically linked to the underlying stock. These instruments have many characteristics of convertible securities and, similarly, will react to variations in the general market for equity securities. Rights are similar to warrants, but normally have a short duration and are distributed directly by the issuer to its shareholders. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.
Zero-Coupon, Step-Coupon and Pay-in-Kind Securities Risk.These securities are debt obligations that do not make regular cash interest payments. Zero-coupon and step-coupon securities are sold at a discount from their face value. Zero-coupon securities do not pay interest until maturity. Step-coupon securities pay coupon interest that increases or decreases over the life of the bond. Pay-in-kind securities pay interest through the issuance of additional securities. Because these securities do not pay current cash income, they are especially sensitive to changes in interest rates, and their prices are generally more volatile than debt securities that pay interest periodically. If an issuer of zero-coupon, step coupon or pay-in-kind securities defaults, a Fund may lose its entire investment. A Fund generally will be required to distribute dividends to shareholders representing the income from these instruments as it accrues, even though such Fund will not receive all of the income on a current basis or in cash. Thus, a Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders.

Management of the Funds
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. The Adviser is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning the Funds’ investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of each Fund. The Adviser utilizes personnel-sharing arrangements with its foreign (non-U.S.) affiliates, Janus Henderson Investors UK Limited ( “JHIUKL”) and Kapstream Capital Pty Limited (Australia) (“Kapstream”), pursuant to which certain Janus Henderson employees, acting for JHIUKL and Kapstream, may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for Kapstream, for Janus Henderson Absolute Return Income Opportunities Fund, and JHIUKL, for Janus Henderson Developed World Bond Fund, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to the Funds on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of a Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate a Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that a Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to a Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for a Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Funds, including providing office space for the Funds and providing personnel to serve as officers to the Funds. The Funds reimburse the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Funds’ Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Funds. The Funds pay these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Funds.
Management expenses
Each Fund pays the Adviser an investment advisory fee and incurs expenses, including administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay.
The following table reflects each Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual compensation rate paid by each Fund to the Adviser after any applicable fee waivers and/or expense reimbursements. The rate shown is a fixed rate based on each Fund’s average daily net assets.

Expense Limitations
With respect to Janus Henderson Absolute Return Income Opportunities Fund, Janus Henderson Flexible Bond Fund, Janus Henderson High-Yield Fund, Janus Henderson Multi-Sector Income Fund, and Janus Henderson Short Duration Flexible Bond Fund, the Adviser has contractually agreed to waive the advisory fee payable by each Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below. In addition, with respect to Janus Henderson Short Duration Flexible Bond Fund, the Adviser shall reimburse or waive out-of-pocket transfer agency/shareholder servicing costs payable by any share class so that such fees do not exceed 0.06% of a share class’ average daily net assets.
With respect to Janus Henderson Developed World Bond Fund, the Adviser has contractually agreed to waive the advisory fee payable by the Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding shareholder servicing fees (but excluding out-of-pocket transfer agency/shareholder servicing costs), acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below.
With respect to Janus Henderson Absolute Return Income Opportunities Fund, Janus Henderson Flexible Bond Fund, and Janus Henderson Multi-Sector Income Fund, the Adviser has also contractually agreed to waive and/or reimburse a portion of each Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated ETFs in which the Fund invests. Pursuant to this agreement, the waiver amount is equal to the amount of Fund assets invested in the affiliated ETFs, multiplied by an amount equal to the current daily unitary management fee of the affiliated ETF, less certain asset-based operating fees and expenses incurred on a per-fund basis and paid by the Adviser with respect to the affiliated ETFs (including, but not limited to custody, sub-administration, transfer agency, legal, and audit fees).

Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund(s) that they manage, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that a Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to that Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares. A further discussion of potential
67 | Janus Investment Fund

conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.

Other information
CLOSED FUND POLICIES
A Fund may limit sales of its Shares to new investors. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Funds
The Funds are distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Funds, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within a single Fund.
Distribution Schedule
Dividends from net investment income for Janus Henderson Developed World Bond Fund are normally declared and distributed monthly. Income dividends for each of the other Funds are normally declared daily (Saturdays, Sundays, and holidays included) and distributed as of the last business day of each month. If a month begins on a Saturday, Sunday, or holiday, dividends for those days are declared and distributed at the end of the preceding month. Income dividends begin accruing the day after a purchase is processed by the Funds or their agents. If shares are redeemed, you will receive all dividends accrued through the day the redemption is processed by the Funds or their agents. Distributions of net capital gains are normally declared and distributed in December. If necessary, dividends and net capital gains may be distributed at other times as well.
How Distributions Affect a Fund’s NAV
Distributions, other than daily income dividends, are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the Shares have been held. Undistributed income and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus Henderson representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
Distribution Options
When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janushenderson.com/individual, by calling a Janus Henderson representative, or by writing to the Funds at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Funds offer the following options:
Reinvestment Option.You may reinvest your income dividends and capital gains distributions in additional shares.
Cash Option.You may receive your income dividends and capital gains distributions in cash.
Reinvest and Cash Option.You may receive either your income dividends or capital gains distributions in cash and reinvest the other in additional shares.
70 | Janus Investment Fund

Redirect Option.You may direct your dividends or capital gains distributions to purchase shares of another Janus Henderson fund.
The Funds reserve the right to reinvest uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Shareholder Services and Account Policies.”
TAXES
As with any investment, you should consider the tax consequences of investing in the Funds. The following is a general discussion of certain federal income tax consequences of investing in the Funds. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of a Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, a Fund that invests in REITs is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of a Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Funds may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
71 | Janus Investment Fund

If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), a Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, the Janus Henderson funds will report cost basis information to you and to the IRS. Each Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Funds
Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If a Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in partnerships, it may be subject to state tax liabilities.

All states have repealed UGMA statutes, enacting UTMA statutes in their place. Existing UGMA accounts established before the date of repeal are grandfathered using the original UGMA age of termination.
Minimum Investment Requirements
Due to the proportionately higher costs of maintaining small accounts, the Funds reserve the right to deduct an annual $25 minimum balance fee per Fund account (paid to the Transfer Agent) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You will receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.
Available Incentive Programs
Bonus Program for Taxable Account Purchases and Tax-Advantaged Account Transfers/Rollovers
Through the Transfer Agent’s Bonus Program, the Transfer Agent will pay a bonus of up to $2,500 to you for making certain eligible purchases of Fund shares in taxable accounts or transfers/rollovers from a non-Janus Henderson fund account into a Janus Henderson fund tax-advantaged account. The Bonus Program is valid with an eligible purchase or transfer/rollover of $20,000 or more. If you meet the eligibility requirements for the Bonus Program and enroll in it, the Transfer Agent will deposit a bonus payment into your Fund account within approximately 30 days after the deposit of eligible funds in good order and receipt of a signed contract governing the Bonus Program. An investor must keep the eligible purchase in the account for a period of 360 calendar days in order to retain the bonus payment. Any sale of the qualifying purchase amount (in whole or in part), transfer, or closure of the account within the 360 calendar day period may result in forfeiture of the bonus payment. Any decline in an account’s value due solely to market value fluctuations will not result in the forfeiture of the bonus payment. Only taxable account purchases or transfers/rollovers to tax-advantaged accounts that are made on or after January 1, 2024 through December 31, 2024 are eligible for a bonus payment. The eligible period for the Bonus Program may be extended beyond this time frame at the sole discretion of the Transfer Agent. Before enrolling in the Bonus Program, consult with your tax advisor about the appropriate tax treatment for the bonus offer and any tax implications associated with the receipt of a bonus payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke this Bonus Program at any time without advance notice.
You can request more information about the Transfer Agent’s Bonus Program and eligibility requirements for taxable accounts by contacting a Janus Henderson representative at 1-800-525-3713 or by visiting www.janushenderson.com/bonus. You can request more information about the Bonus Program for tax-advantaged account transfers/rollovers by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Contribution Match Payments
Investors that transfer/rollover assets from a non-Janus Henderson fund account into a tax-advantaged account are also eligible for the Transfer Agent’s Contribution Match Program. To receive a Transfer Agent’s Contribution Match payment, (i) the value of your tax-advantaged account must remain equal to or greater than the value of the eligible transfer/rollover (but not including any losses due solely to market value fluctuations) for 12 months following the receipt of your transfer/rollover in good order and receipt of a signed contract governing the Contribution Match Program, and (ii) you must provide instructions to the Transfer Agent on how to invest these payments. The Transfer Agent’s Contribution Match payments will commence at the end of the first quarter in 2025 following an eligible contribution during the first quarter of 2025 into a Janus Henderson fund tax-advantaged account. The eligible period for the Transfer Agent’s Contribution Match payments may be extended beyond this time frame at the sole discretion of the Transfer Agent. The Transfer Agent will match a percentage of these contributions based on the aggregate value of eligible 2024 rollover or asset transfer amounts, and provide a matching contribution in an amount up to ten percent of your contribution. Before enrolling in the Contribution Match Program, consult with your tax advisor about the appropriate tax treatment for the Transfer Agent’s Contribution Match payments and any tax implications associated with the receipt of a Contribution Match payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Contribution Match Program at any time without advance notice.

Ready. Invest. Go. Program
New investors creating a new Janus Henderson direct account are eligible to participate in the Transfer Agent’s Ready. Invest. Go. Program. After the new investor has completed the required Ready. Invest. Go. Program Contract, the Transfer Agent will fund the $100 initial investment required for new investors, provided that new investors enroll in Janus Henderson’s automatic investment program in an amount equal to at least $50 per month. New investors will forfeit the $100 bonus contributed by the Transfer Agent if their account is closed or if their automatic monthly investment program payment is terminated within two years from the date the initial investment was made. Investor-initiated amounts outside of the initial investment are redeemable at any time at net asset value. Before enrolling in the Ready. Invest. Go. Program, new investors should consult with their tax advisor about the appropriate tax treatment for participating in the Ready. Invest. Go. Program and any tax implications associated with the receipt of the $100 initial investment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Ready. Invest. Go. Program at any time without advance notice.

Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. A Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which a Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by a Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.
77 | Janus Investment Fund

All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after a request is received in good order by a Fund or its agents. Each Fund’s per share class NAV is available at janushenderson.com/nav (or janushenderson.com/pricing for all other available share classes).
Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange, including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of a Fund’s portfolio securities and the reflection of such change in a Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of a Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by a Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used.
78 | Janus Investment Fund

Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.
Policies in Relation to Transactions
All requests, including but not limited to, exchanges between a Fund and other Janus Henderson funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus Henderson’s P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase.
Administrative services fees
The Funds pay an annual administrative services fee based on the average daily net assets of Class D Shares, as detailed below.
Average Daily Net Assets of Class D Shares of the Janus Henderson funds
Administrative Services Fee
Under $40 billion
0.12%
$40 billion - $49.9 billion
0.10%
Over $49.9 billion
0.08%
These administrative services fees are paid by Class D Shares of each Fund. The Transfer Agent provides or arranges for the provision of shareholder services including, but not limited to, recordkeeping, accounting, answering inquiries regarding accounts, transaction processing, transaction confirmations, and the mailing of prospectuses and shareholder reports.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary and when considering which share class of a fund is most appropriate.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’
79 | Janus Investment Fund

share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you.
Paying for shares
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to buy shares.
Please note the following when purchasing Shares:
Cash, credit cards, third party checks (with certain limited exceptions), travelers cheques, credit card checks, line of credit checks, or money orders will not be accepted.
All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted non-U.S. bank.
Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.
When purchasing Shares through the Automatic Investment Program, your automatic investment selection(s) will generally be active within three days following receipt of your authorization for the date and amount you specify. If no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. If the balance in the Janus Henderson fund account you are buying into falls to zero as the result of a redemption, exchange, or minimum balance fee, your Automatic Investment Program will be discontinued.
We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Funds by submitting good funds via another method accepted by the Funds (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.
Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”
If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as applicable, will be invested in Janus Henderson Government Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus Henderson to (i) buy shares of another Janus Henderson fund or (ii) sell shares of Janus Henderson Government Money Market Fund and return the proceeds (including any dividends earned) to you, Janus Henderson will treat your inaction as approval of the purchase of Janus Henderson Government Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus Henderson for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Henderson Government Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Henderson Government Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will
80 | Janus Investment Fund

be automatically exchanged from Janus Henderson Government Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”
For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.
If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and any losses incurred by a Fund as a result. A Fund may redeem shares held in your account to cover any losses it incurs if your purchase is cancelled.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), the Adviser is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, the Adviser may temporarily limit additional share purchases. In addition, the Adviser may close an account if it is unable to verify a shareholder’s identity. Please contact a Janus Henderson representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
The Funds have also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Funds are required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.
Exchanges
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Please note the following when exchanging Shares:
An exchange represents the redemption (or sale) of shares from one Fund and the purchase of shares of another Fund, which may produce a taxable gain or loss in a non-retirement account.
You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. A Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.
New regular Janus Henderson fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus Henderson fund account you are exchanging from is less than $2,500 ($100 for new regular Fund accounts with an automatic investment program of $50 per month). (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
81 | Janus Investment Fund

UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus Henderson fund account you are exchanging from is less than the stated minimum, you must exchange the entire balance. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
New Janus Henderson fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
Exchanges between existing Janus Henderson fund accounts must meet the $50 subsequent investment requirement.
For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus Henderson fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. Different restrictions may apply if you invest through an intermediary.
Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
With certain exceptions, exchanges between Janus Henderson fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus Henderson fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.
If the shares you are exchanging are held in certificate form, you must return the certificate to Janus Henderson prior to making any exchanges. Shares are no longer available in certificate form.

Payment of redemption proceeds
As previously noted, with certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Funds.
By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.
Next Day Wire Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.
ACH (Automated Clearing House) Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on or about the next bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.
By Check – Redemption proceeds will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.
82 | Janus Investment Fund

By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus Henderson fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.
The Funds typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Generally, orders to sell Shares may be initiated at any time at janushenderson.com/individual, by telephone, or in writing. Certain accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Funds can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide alternate instructions, your proceeds will be invested in Shares of Janus Henderson Government Money Market Fund during the 15-day hold period.
Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. A temporary hold may also be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult has occurred, is occurring, has been attempted, or will be attempted, as described under “Temporary Suspension of Services.”
Note: For the fastest and easiest way to redeem shares, log on to janushenderson.com/individual* 24 hours a day, 7 days a week.

Certain account types and transactions are not available via janushenderson.com. For more information, access janushenderson.com/individual or refer to this Shareholder’s Manual.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these large shareholders of their holdings in a Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect a Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If a Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
83 | Janus Investment Fund

While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Written Instructions
To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus Henderson.” Requests or documents received in a language other than English may be inadvertently delayed or returned due to an inability to accurately translate the intended instructions. Please include the following information:
the name of the Janus Henderson fund(s) being redeemed or exchanged;
the account number(s);
the amount of money or number of shares being redeemed or exchanged;
the name(s) on the account;
the signature(s) of one or more registered account owners; and
your daytime telephone number.
Signature Guarantee
A signature guarantee for each registered account owner is required if any of the following is applicable:
You request a redemption by check above a certain dollar amount.
You would like a check made payable to anyone other than the shareholder(s) of record.
You would like a check mailed to an address that has been changed within 10 days of the redemption request.
You would like a check mailed to an address other than the address of record.
You would like your redemption proceeds sent to a bank account other than a bank account of record.
The Funds reserve the right to require a signature guarantee under other circumstances or to reject or delay a redemption on certain legal grounds.
A signature guarantee may be refused if any of the following is applicable:
It does not appear valid or in good form.
The transaction amount exceeds the surety bond limit of the signature guarantee.
The guarantee stamp has been reported as stolen, missing, or counterfeit.
How to Obtain a Signature Guarantee
A signature guarantee assures that a signature is genuine. The signature guarantee protects shareholders from unauthorized account transfers. The following financial institutions may guarantee signatures: banks, savings and loan associations, trust companies, credit unions, broker-dealers, and member firms of a national securities exchange. Call your financial institution to see if it has the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Funds are intended for long-term investment purposes, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies and procedures may be cancelled or rescinded by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Funds are also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
84 | Janus Investment Fund

fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Funds monitor for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds at all times reserve the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund.
The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.
In an attempt to deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Funds’ excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Funds by a collective investment trust managed by the Adviser; (iv) transactions in the Funds by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.
Excessive Trading Risks
Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of a Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by a Fund despite the Funds’ adoption of policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Funds to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive
85 | Janus Investment Fund

trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of each Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for each Fund at janushenderson.com/reports. A complete schedule of each Fund’s portfolio holdings is also available in the annual and semiannual financial statements located in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. Each Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
Top Holdings.Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), top/bottom issuers ranked by performance attribution, and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom issuers may include the percentage of attribution to Fund performance, average Fund weighting, and other relevant data points.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Funds’ Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.
Shareholder services and account policies
Address Changes
For the easiest way to change the address on your account, visit janushenderson.com/individual. You may also call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Include the name of the Janus Henderson fund(s) you hold, the account number(s), the name(s) on the account, and both the old and new addresses. Certain options may be suspended for 10 days following an address change unless a signature guarantee is provided.
Bank Account Changes
For the easiest way to change your bank account of record or add new bank account information to your account, visit janushenderson.com/individual. You may also send a written request signed by the shareholder of record or by each shareholder of record if more than one. Certain accounts may require a written notice and, in some instances, bank privileges may not be available. If multiple account owners are named on the added bank account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.
You may revoke the authorization to use your bank account information at any time by visiting janushenderson.com/individual, or by sending a written request by mail (Janus Henderson, P.O. Box 219109, Kansas City, MO 64121-9109), or by telephone at 1-800-525-3713. Your request will be processed within a reasonable amount of time upon its receipt.
86 | Janus Investment Fund

Distributions
Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janushenderson.com/individual, call a Janus Henderson representative, or send a written request signed by one or more shareholder(s) of record.
Your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.
Involuntary Redemptions
The Funds reserve the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Funds. This includes, but is not limited to, accounts that a Fund or its agents believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.
Lost (Unclaimed/Abandoned) Accounts
It is important that the Funds maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Funds as undeliverable. Based upon statutory requirements for returned mail, the Adviser will attempt to locate the shareholder or rightful owner of the account. If the Adviser is unable to locate the shareholder, then the Adviser is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
Online and Telephone Transactions
You may initiate many transactions through janushenderson.com/individual or by calling Janus Henderson XpressLine. You may also contact a Janus Henderson representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please call a Janus Henderson representative. The Funds and their agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.
Your ability to access your account or transact business electronically may be impacted due to unexpected circumstances, such as system outages, or during periods of increased web activity. For example, periods of substantial market change or other unexpected events can contribute to high call volumes, which may delay your ability to reach a Janus Henderson representative by telephone.
If you experience difficulty transacting business with us through a particular method, please consider using an alternate method, such as visiting janushenderson.com/individual, calling Janus Henderson XpressLine, contacting a Janus Henderson representative by telephone, or sending written instructions to complete your transaction. Please remember that purchase, exchange, or redemption requests must be received in good order by a Fund or its agents prior to the close of the trading session of the NYSE in order to receive that day’s NAV.
Your account information, including online credentials, should be kept private, and you should immediately review any account statements that you receive from Janus Henderson. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus Henderson immediately about any transactions you believe to be unauthorized.
Registration Changes
To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janushenderson.com/individual or call a Janus Henderson representative for further instructions.
Statements, Reports, and Prospectuses
We will send you a confirmation upon the completion of individual account transactions. We will also send you quarterly account statements detailing financial transactions on open accounts processed year-to-date. Systematic transactions are
87 | Janus Investment Fund

confirmed on quarterly statements unless otherwise requested. Confirmations and quarterly account statements will be sent to the account address of record unless you have elected to receive online statements. The Funds reserve the right to charge a fee for additional account statement requests.
At account setup, or any time thereafter, you may elect (at janushenderson.com/edelivery) to discontinue physical delivery of quarterly account statements and/or confirmations, and instead receive an e-mail notification when they are available online. All statements are available online regardless of your delivery option elections (to view, you must first establish online access at janushenderson.com/individual).
The Funds produce shareholder reports semiannually, and update their prospectus annually. You may elect to receive shareholder reports and prospectus updates electronically at janushenderson.com/edelivery. The Funds’ fiscal year ends June 30.
Unless you instruct Janus Henderson otherwise by contacting a Janus Henderson representative, the Funds will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Funds receive your instructions.
Taxpayer Identification Number
On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Funds to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Funds for any penalty that the IRS may impose.
Temporary Suspension of Services
The Funds or their agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Funds may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Funds to redeem their Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.
In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (i) a natural person age 65 and older, or (ii) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests. We may not be aware of factors suggesting financial exploitation of a Specified Adult and may not be able to identify Specified Adults in all circumstances. Furthermore, we are not required to delay the disbursement of redemption proceeds and do not assume any obligation to do so.

Financial highlights
The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if applicable. The information for the Funds for the fiscal periods ended June 30 has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in each Fund’s Form N-CSR and is incorporated by reference into the SAI.
The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in Class D Shares of the Funds (assuming reinvestment of all dividends and distributions).

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Collateralized Loan Obligations (“CLOs”) are a type of structured credit, which is a sector of the fixed income market that also includes asset-backed and mortgage- backed securities. Typically organized as a trust or other special purpose vehicle, a CLO issues debt and equity interests and uses the proceeds from this issuance to acquire a portfolio of bank loans made primarily to businesses that are rated below investment grade.
Collateralized Mortgage Obligations (“CMOs”) are a type of mortgage-backed security that are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams (tranches) with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches are frequently referred to as “mortgage derivatives” and may be extremely sensitive to changes in interest rates. The issuer of a series of CMOs may elect to be treated as a Real Estate Mortgage Investment Conduit (“REMIC”). A REMIC is a CMO that qualifies for special tax treatment and invests in certain mortgages principally secured by interests in real property and other permitted investments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. A Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Credit Risk Transfer Securities (“CRTs”) are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as a Fund have no direct recourse to the underlying mortgage loans in the event of a default.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Duration is a measurement of price sensitivity to interest rate changes. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by a Fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, a Fund’s duration is usually shorter than its average maturity. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter duration. For example, the price of a bond portfolio with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. A Fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise.

Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
High-yield bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba1 or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.
Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Pay-in-kind bonds are debt securities that normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Private placements are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Rule 144A securities are securities that are not registered for sale to the general public under the Securities Act of 1933, as amended, but that may be resold to certain institutional investors.
Step coupon bonds are issued and traded at a discount from their face value and pay coupon interest that increases or decreases over the life of the bond. The discount from the face amount or par value depends on the time remaining until cash payments begin, prevailing interest rates, liquidity of the security and the perceived credit quality of the issuer.
96 | Janus Investment Fund

“To be announced” or “TBA” commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining a Fund’s net asset value. Because a Fund is generally not required to pay for the security until the settlement date, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
Zero coupon bonds are debt obligations that do not pay regular cash interest payments at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form.
Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
97 | Janus Investment Fund

Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Inflation index swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments or an exchange of floating rate payments based on two different reference indices). By design, one of the reference indices is an inflation index, such as the Consumer Price Index.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Inverse floaters are debt instruments whose interest rate bears an inverse relationship to the interest rate on another instrument or index. For example, upon reset, the interest rate payable on the inverse floater may go down when the underlying index has risen. Certain inverse floaters may have an interest rate reset mechanism that multiplies the effects of change in the underlying index. Such mechanism may increase the volatility of the security’s market value.
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.
Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period. A fixed-income total return swap may be written on many different kinds of underlying reference assets, and may include different indices for various kinds of debt securities (e.g., U.S. investment grade bonds, high-yield bonds, or emerging market bonds).
Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Net long is a term used to describe when a Fund’s assets committed to long positions exceed those committed to short positions.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Short sales in which a Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain.
98 | Janus Investment Fund

When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.63%. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated exchange traded funds (“ETFs”) in which the Fund invests, less certain operating expenses. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 61% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. For purposes of this 80% policy, the term bonds refers to a variety of fixed-income securities and instruments, and includes, but is not limited to, such investments as government notes and bonds, corporate bonds, convertible securities, commercial paper, commercial and residential mortgage-backed securities, asset-backed securities, collateralized loan obligations, fixed rate notes, floating rate securities, and derivatives such as forwards, swap agreements, futures contracts, and options that provide exposure to various fixed-income instruments (“Fixed-Income Instruments”). The Fund may invest a significant portion of its assets in certain types of Fixed-Income Instruments, including mortgage-backed securities. In pursuing its investment objective, the Fund will have exposure to investments that are economically tied to a number of countries throughout the world.
The Fund employs an “absolute return” strategy, which means that the Fund benchmarks itself to an index of cash instruments, rather than a fixed-income index. In pursuing this strategy, the Fund seeks to achieve positive returns that exceed its performance benchmark index in a variety of market environments. The Fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income, while at the same time seeking to provide low volatility. The Fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed-income market. For example, portfolio management may favor investments in smaller countries or regions that tend to be underrepresented in fixed-income indices that are more heavily focused on the United States or other larger regions globally. Portfolio management uses research which encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models. A position may be sold if it reaches its total return target, if the investment thesis for owning it changes, or to limit potential losses.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data,
3 | Janus Henderson Absolute Return Income Opportunities Fund

and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund’s average portfolio duration may range from negative two years to plus four years. As of June 30, 2024, the Fund’s average portfolio duration was 1.29 years. The Fund may invest in securities of varying maturities, although the Fund’s average portfolio maturity is generally less than five years. While the Fund primarily invests in investment-grade debt securities, it may invest up to 25% of its assets in high-yield bonds (also known as “junk” bonds). The Fund may invest in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers.
The Fund may invest in foreign debt securities. At times, the Fund may invest a substantial amount of its assets in foreign debt issuers located in a single region. The Fund will normally limit its foreign currency exchange exposure to 15% of its total assets. The Fund may limit its foreign currency exchange exposure by hedging through the use of forward contracts, cross-currency swaps, currency futures, and options. The Fund may invest in cash or cash equivalents such as short-term government bonds, commercial paper, repurchase agreements, and other short-duration fixed-income securities. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
The Fund may invest in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may utilize interest rate futures, interest rate swaps, credit default swaps (both single-name and index), options, swaptions, and currency forwards for various investment purposes, such as to manage or hedge portfolio risk, enhance return, or manage duration. The Fund may engage in short sales of derivatives instruments such as options, futures, and swaps.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even
4 | Janus Henderson Absolute Return Income Opportunities Fund

normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Geographic Concentration Risk.To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.
Australia Risk.The Fund’s investment in Australian issuers may subject the Fund to loss in the event of adverse tax, political, economic, regulatory, and other developments that affect Australia and its fixed-income markets, including fluctuations of Australian currency versus the U.S. dollar. Also, Australia is economically sensitive to environmental events and is located in a part of the world that has historically been prone to natural disasters, such as drought and flooding.
Derivatives Risk.Derivatives, such as swaps, futures, forwards, and options, can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Swap agreements also bear the risk that the Fund will not be able to meet its obligation to the counterparty. The Fund’s investments in interest rate futures in particular entail the risk that portfolio management’s prediction of the direction of interest rates is wrong, and the Fund could incur a loss. If the Fund invests a significant portion of its assets in derivatives, its investment performance could be dependent on securities not directly owned by the Fund. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer,
5 | Janus Henderson Absolute Return Income Opportunities Fund

or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.
Currency Risk.Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Although the Fund seeks to provide long-term positive returns, market conditions or implementation of the Fund’s investment process may result in losses, and, in such circumstances, the Fund will not meet its investment objective. As such, there can be no assurance of positive “absolute” returns.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class T Shares of the Fund commenced operations with the Fund’s inception. Class R Shares of the Fund commenced operations on February 6, 2015.
The performance shown for Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class T Shares is calculated using the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The performance shown for Class R Shares for periods prior to February 6, 2015, reflects the performance of the Fund’s Class I Shares, calculated using the fees and expenses of Class R Shares, without the effect of any fee and expense

limitations or waivers. If Class R Shares of the Fund had been available during periods prior to February 6, 2015, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class R Shares reflects the fees and expenses of Class R Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the FTSE 3-Month U.S. Treasury Bill Index to the Bloomberg U.S. Aggregate Bond Index due to regulatory requirements. The Fund retained the FTSE 3-Month U.S. Treasury Bill Index as a performance benchmark because the FTSE 3-Month U.S. Treasury Bill Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
The FTSE 3-Month U.S. Treasury Bill Index is an unmanaged index designed to represent the average of Treasury bill rates for each of the prior 3 months, adjusted to a bond equivalent basis.
After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees (but excluding out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees), acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.57% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds or other income-producing debt-related securities from developed countries. The Fund considers “developed countries” to include, but not be limited to, those countries characterized as developed by the MSCI World Indexsm, including the United States, United Kingdom, Canada, Australia, Sweden, Denmark, Japan, Austria, Belgium, Finland, France, Germany, New Zealand, the Netherlands, and Switzerland, or such other countries as portfolio management deems to be developed.
Under normal circumstances, portfolio management intends to invest at least 40% of the Fund’s net assets outside of the United States and in at least three different countries. A security is deemed to originate in a country if one or more of the following tests are met: (i) the company is organized in, or its primary business office or principal trading market of its equity is located in, the country, (ii) a majority of the company’s assets are located in the country, or (iii) a majority of the company’s revenues are derived from the country. The Fund may also invest up to 20% of its net assets in equity and equity-related securities such as convertibles and debt securities with warrants. While the Fund has no policy limiting the currency in which foreign securities may be denominated, the Fund seeks to hedge its non-dollar investments back to the U.S. dollar.
Portfolio management uses a process that combines a bottom-up approach to individual security selection rooted in thorough, independent research with a macro-economic overlay that determines appropriate country, asset sector, currency and industry exposure. In their bottom-up approach, portfolio management uses both qualitative and quantitative credit analysis to consider a variety of factors, including the issuer’s experience, managerial strength, debt service capability, operating outlook, sensitivity to economic conditions, current financial condition, liquidity and access to capital, asset protection, structural issues, covenant protection, and equity sponsorship.
Portfolio management meets with prospective and purchased debt issuers. They also work closely with a team of analysts to search for the most appropriate securities to include in the Fund’s portfolio.
Sector, regional and industry allocations are evaluated within a broader economic and market context and involve: (i) evaluation of the economic and interest rate environment that determines asset sector allocation and quality mix; (ii) evaluation of country and regional economic environment to support country allocation decisions; and (iii) analysis of industry weightings, including stability and growth of industries, cash flows and/or positive equity momentum.
12 | Janus Henderson Developed World Bond Fund

As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG risks and opportunities are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
Portfolio management seeks to (i) avoid corporate issuers that are significantly engaged in business activities that they believe may be environmentally and/or socially harmful, as discussed below; (ii) invest in a portfolio of corporate issuers that, in the aggregate, has a lower carbon intensity and/or footprint than the ICE BofA Global Corporate & High Yield Index on a monthly basis; (iii) avoid sovereign bond issuers that (a) have been sanctioned by the European Union or United Nations or have insufficient rankings with respect to political rights and civil liberties, as measured by third-party inputs, or (b) have not ratified the Paris Climate Accord.
To identify the universe of investible securities for the Fund, portfolio management applies broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that derive more than de minimis revenue from certain activities considered by portfolio management to be environmentally and/or socially harmful. A current list of such business activities, which may evolve over time, follows:
oil and gas generation and production;
oil sands extraction;
shale energy extraction;
thermal coal extraction and power generation;
Arctic oil and gas extraction;
tobacco;
fur;
adult entertainment;
gambling or controversial weapons; and
United Nations Global Compact violators.
The Fund does not apply the avoidance criteria noted above in managing the Fund’s exposure to cash and cash equivalents, U.S. Treasuries, and credit default swaps on indices.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is significant deterioration in company fundamentals, an inability to maintain open communication with management, a change in business strategy, a change in issuer-specific business outlook, realization of anticipated gains, or a failure by the issuer to meet operating/ financial targets. The Fund will also consider selling a security if, in portfolio management’s opinion, it no longer meets the environmental or social criteria noted above, or a superior investment opportunity arises.
Securities in which the Fund may invest include: all types of bonds, debentures, mortgage-related and other asset-backed securities, investment grade debt securities (including corporate debt, developed market government bonds, and U.S. Government securities), high yield securities (also known as “junk” bonds), foreign securities, subordinated bank debt, collective investment schemes, domestic or foreign floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. Portfolio management may shift the Fund’s assets among various types of income-producing securities based upon changing market conditions. The Fund’s average portfolio duration normally may range from zero to plus nine years. Portfolio management may lengthen or shorten the Fund’s duration based on their outlook on interest rates and inflation. The Fund may invest in issuers of any credit quality. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
The Fund may engage in exchange-traded or over-the-counter derivative transactions to seek return, to generate income, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to change the effective duration of the portfolio, to manage certain investment risks, or as a substitute for the purchase or sale of securities or currencies. To the extent derivatives are used, the Fund expects to use them principally when seeking to hedge currency exposure using forward foreign currency contracts, to obtain net long or net negative (short) exposures to selected interest rate, duration or credit risks using a combination of bond or interest rate futures contracts, options on bond or interest rate futures contracts, and
13 | Janus Henderson Developed World Bond Fund

interest rate, inflation rate and credit default swap agreements. The Fund may invest in credit default swaps to gain issuer exposure or to gain sector exposure. The Fund may take short positions on derivatives instruments.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Geographic Concentration Risk.To the extent the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.
Europe Risk.The Fund is subject to certain risks associated with Europe and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent. Changes in regulations on trade, decreasing imports or exports, changes in the exchange rate of European currencies, and recessions among European countries may have a significant adverse effect on the economies of other European countries. Western
14 | Janus Henderson Developed World Bond Fund

Europe has, in certain instances, been susceptible to serious financial hardship, high debt levels, and high levels of unemployment. The markets in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Industry and Sector Risk.Although the Fund does not concentrate its investments in specific industries, it may have a significant portion of its assets invested in securities of companies conducting similar business or businesses within the same economic sector. Companies in the same industry or economic sector may be similarly affected by negative economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
ESG Investment Risk.Because the Fund considers ESG Factors in selecting securities, the Fund may perform differently than funds that do not consider ESG Factors. Due to the ESG considerations and exclusionary criteria employed by the Fund, the Fund may not be invested in certain industries or sectors, and therefore may have lower performance than portfolios that do not apply similar criteria. ESG-related information provided by issuers and third parties, which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for ESG investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing companies to consider their environmental or social practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the issuers identified through the investment process employed by the Fund may fail to adhere to positive environmental or social practices, which may result in selling a security when it might otherwise be disadvantageous to do so.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
15 | Janus Henderson Developed World Bond Fund

Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Returns shown for periods prior to June 5, 2017, are those of Henderson Strategic Income Fund (the “Predecessor Fund”). The Predecessor Fund was advised by Henderson Global Investors (North America) Inc. and subadvised by Henderson Investment Management Limited. Class A Shares, Class C Shares, Class I Shares, and Class R6 Shares of the Predecessor Fund were reorganized into Class A Shares, Class C Shares, Class I Shares, and Class N Shares, respectively, of the Fund on June 2, 2017. Class A Shares and Class C Shares of the Predecessor Fund commenced operations with the Predecessor Fund’s inception on September 30, 2003. Class I Shares and Class R6 Shares of the Predecessor Fund commenced operations on April 29, 2011 and November 30, 2015, respectively. Class S Shares and Class T Shares of the Fund commenced operations on June 5, 2017.
The performance shown for Class A Shares for periods prior to June 5, 2017, reflects the performance of Class A Shares of the Predecessor Fund and is calculated using the fees and expenses of Class A Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class C Shares for periods prior to June 5, 2017, reflects the performance of Class C Shares of the Predecessor Fund and is calculated using the fees and expenses of Class C Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class I Shares for periods prior to June 5, 2017, reflects the performance of Class I Shares of the Predecessor Fund and is calculated using the fees and expenses of Class I Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers, except that for periods prior to April 29, 2011, performance shown for Class I Shares reflects the performance of Class A Shares of the Predecessor Fund, calculated using the fees and expenses of Class A Shares of the Predecessor Fund (without sales charges), net of any applicable fee and expense limitations or waivers.
The performance shown for Class N Shares for periods prior to June 5, 2017, reflects the performance of Class R6 Shares of the Predecessor Fund and is calculated using the fees and expenses of Class R6 Shares of the Predecessor Fund, in effect during the periods shown, net of any applicable fee and expense limitations or waivers, except that for periods prior to
16 | Janus Henderson Developed World Bond Fund

November 30, 2015, performance shown for Class N Shares reflects the performance of Class A Shares of the Predecessor Fund, calculated using the fees and expenses of Class A Shares of the Predecessor Fund (without sales charges), net of any applicable fee and expense limitations or waivers.
The performance shown for Class S Shares for periods prior to June 5, 2017, reflects the performance of Class A Shares of the Predecessor Fund, calculated using the fees and expenses of Class A Shares of the Predecessor Fund (without sales charges), net of any applicable fee and expense limitations or waivers.
The performance shown for Class T Shares for periods prior to June 5, 2017, reflects the performance of Class A Shares of the Predecessor Fund, calculated using the fees and expenses of Class A Shares of the Predecessor Fund (without sales charges), net of any applicable fee and expense limitations or waivers.
Returns of the Fund will be different from the Predecessor Fund as they have different expenses.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s (and the Predecessor Fund’s) past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Bloomberg Global Aggregate Credit Index (USD Hedged) to the Bloomberg Global Aggregate Bond Index due to regulatory requirements. The Fund retained the Bloomberg Global Aggregate Credit Index (USD Hedged) as a performance benchmark because the Bloomberg Global Aggregate Credit Index (USD Hedged) is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg Global Aggregate Bond Index is a broad-based measure of the global investment grade fixed-rate debt markets.
The Bloomberg Global Aggregate Credit Index (USD Hedged) is the credit component of the Bloomberg Global Aggregate Index, which provides a broad-based measure of the global investment grade fixed income markets. The credit component excludes government bonds and securitized debt.
After-tax returns are calculated using distributions for the Predecessor Fund’s Class A Shares for the period prior to June 5, 2017. If Class A Shares of the Fund had been available during periods prior to June 5, 2017, the distributions used to

calculate the after-tax returns may have been different. After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class A Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class A Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses a fund may incur as a result of investing in shares of an underlying fund. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(2)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.40%. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated exchange traded funds (“ETFs”) in which the Fund invests, less certain operating expenses. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends

and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year period reflects the conversion to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 170% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by primarily investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. Bonds include, but are not limited to, government notes and bonds, corporate bonds, commercial and residential mortgage-backed securities, asset-backed securities, credit risk transfer securities (“CRTs”), and money market instruments. The Fund may invest in fixed and floating rate obligations with varying durations. The Fund’s average portfolio duration typically ranges between three and seven years. As of June 30, 2024, the Fund’s average portfolio duration was 6.43 years.
The Fund will invest at least 65% of its net assets in investment grade debt securities. The Fund will limit its investment in high-yield bonds (also known as “junk” bonds) to 35% or less of its net assets. The Fund generates total return from a combination of current income and capital appreciation, but income is usually the dominant portion. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The Fund also invests in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities. The Fund may also invest in foreign securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may use interest rate swaps and futures, including Treasury bond futures, to manage interest rate risk, yield curve positioning, and country exposure. The Fund may also use index credit default swaps for hedging purposes (to offset risks associated with an investment exposure, or market conditions), to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund relative to its benchmark index, and to earn income, enhance returns, or preserve capital. The Fund’s exposure to derivatives will vary. For purposes of meeting its 80%
22 | Janus Henderson Flexible Bond Fund

investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The Fund may take short positions on derivatives instruments.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
23 | Janus Henderson Flexible Bond Fund

High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Credit Risk Transfer Securities Risk.CRTs are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored enterprises or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. These risks are in addition to the risks described under “Fixed-Income Securities Risk.”
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders in a taxable account.
TBA Commitments Risk.Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and
24 | Janus Henderson Flexible Bond Fund

settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund commenced operations on July 6, 2009. Class N Shares of the Fund commenced operations on May 31, 2012.
The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class R Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.
25 | Janus Henderson Flexible Bond Fund

The performance shown for Class N Shares for periods prior to May 31, 2012, reflects the performance of the Fund’s Class T Shares, calculated using the fees and expenses of Class T Shares, net of any applicable fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, or Class N Shares of the Fund had been available during periods prior to May 31, 2012, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

The Fund’s broad-based benchmark index is the Bloomberg U.S. Aggregate Bond Index. The index is described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class R Shares, or Class T Shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.63% for at least a one-year period commencing on October 28, 2024. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 87% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objectives by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in high-yield securities rated below investment grade (also known as “junk” bonds). Securities rated below investment grade may include their unrated equivalents or other high-yielding securities portfolio management believes offer attractive risk/return characteristics. The Fund may at times invest all of its assets in such securities. The Fund may also invest in money market instruments and foreign debt securities. The Fund may also invest in floating rate obligations, such as collateralized loan obligations, floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. The Fund’s exposure to derivatives will vary. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. In particular, the Fund may invest in swaps, including index credit default swaps, to increase or decrease the Fund’s exposure to a particular market.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data,
30 | Janus Henderson High-Yield Fund

and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is
31 | Janus Henderson High-Yield Fund

also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. To the extent the Fund invests in foreign debt securities, such investments are sensitive to changes in interest rates. Additionally, investments in securities of foreign governments involve the risk that a foreign government may not be willing or able to pay interest or repay principal when due.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund commenced operations on July 6, 2009. Class N Shares of the Fund commenced operations on May 31, 2012.
The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
32 | Janus Henderson High-Yield Fund

The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class R Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
The performance shown for Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of Class J Shares, net of any applicable fee and expense limitations or waivers.
The performance shown for Class N Shares for periods prior to May 31, 2012, reflects the performance of the Fund’s Class T Shares, calculated using the fees and expenses of Class T Shares, net of any applicable fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class R Shares of the Fund had been available during periods prior to July 6, 2009, or Class N Shares of the Fund had been available during periods prior to May 31, 2012, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class R Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Bloomberg U.S. Corporate High-Yield Bond Index to the Bloomberg U.S. Aggregate Bond Index due to regulatory requirements. The Fund retained the Bloomberg U.S. Corporate High-Yield Bond Index as a performance benchmark because the Bloomberg U.S. Corporate High-Yield Bond Index is more closely aligned with the Fund’s investment strategies and investment restrictions. The indices are described below.
The Bloomberg U.S. Aggregate Bond Index is made up of U.S. dollar-denominated, fixed-rate taxable bonds, including securities that are of investment grade quality or better.
The Bloomberg U.S. Corporate High-Yield Bond Index is composed of fixed-rate, publicly issued, non-investment grade debt.
After-tax returns are calculated using distributions for the Fund’s Class T Shares (formerly named Class J Shares, the initial share class). After-tax returns are calculated using the historically highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your individual tax situation and may differ from those shown in the preceding table. The after-tax return information shown above does not apply to Fund shares held through a tax-advantaged account, such as a 401(k) plan or an IRA.
After-tax returns are only shown for Class T Shares of the Fund. After-tax returns for the other classes of Shares will vary from those shown for Class T Shares due to varying sales charges (as applicable), fees, and expenses among the classes.

“Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. Acquired fund fees and expenses are indirect expenses a fund may incur as a result of investing in shares of an underlying fund. To the extent that the Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds.
(3)
The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.64%. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated exchange traded funds (“ETFs”) in which the Fund invests, less certain operating expenses. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends

and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares after eight years. The Example for Class C Shares for the ten-year period reflects the conversion to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.
Principal investment strategies
The Fund pursues its investment objective by primarily investing, under normal circumstances, in a multi-sector portfolio of U.S. and non-U.S. debt securities of varying maturities that portfolio management believes have high income potential relative to other fixed-income instruments available at a given point in time. Portfolio management may also consider the capital appreciation potential of certain investments. The Fund’s investment sectors include, but are not limited to: (i) government notes and bonds; (ii) corporate bonds, including high-yield bonds (also known as “junk” bonds); (iii) commercial loans; (iv) agency and non-agency commercial and residential mortgage-backed securities; (v) asset-backed securities; (vi) convertible securities and preferred stock; and (vii) emerging market debt. Portfolio management believes that by investing in multiple sectors that potentially have low correlation to each other, the Fund’s overall volatility may be reduced. The Fund may not have exposure to all of these investment sectors, and the Fund’s exposure to any one investment sector will vary over time. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.
The Fund’s investments in below investment grade securities are limited to 65% of its net assets, but under unusual circumstances, such as when new issue allocations are higher than expected, this limit may be exceeded on a temporary basis.
The Fund may invest up to 50% of its total assets in the commercial loans sector. Such investments may include bank loans, bridge loans, debtor-in-possession (“DIP”) loans, mezzanine loans, and other fixed and floating rate loans. Normally, the Fund’s exposure to the commercial loans sector will be approximately 15% of the Fund’s total assets. The Fund may invest in floating rate obligations, including collateralized loan obligations, credit risk transfer securities (“CRTs”), floating rate senior secured syndicated bank loans, floating rate unsecured loans, and other floating rate bonds, loans and notes. The Fund may also invest in zero-coupon bonds. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities.
38 | Janus Henderson Multi-Sector Income Fund

Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may use swaps, including index credit default swaps, commercial mortgage-backed securities index swaps, and single-name credit default swaps, forward currency exchange contracts, interest rate futures, and put and call options. The Fund may use derivatives for various investment purposes including for hedging purposes, such as to manage portfolio risk or currency risk, to enhance returns, or manage duration. The Fund’s exposure to derivatives will vary. The Fund may engage in short sales of derivatives instruments.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment
39 | Janus Henderson Multi-Sector Income Fund

opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
Loan Risk.Bank loans are obligations of companies or other entities sometimes entered into in connection with recapitalizations, acquisitions, and refinancings. The Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged. Loans are subject to credit risk, interest rate risk, and liquidity risk. Investments in certain commercial loans, such as bridge loads, DIP loans, and mezzanine loans subject the Fund to other risks. Bridge loans involve certain risks in addition to those associated with bank loans, including the risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets. Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Credit Risk Transfer Securities Risk.CRTs are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored enterprises or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. These risks are in addition to the risks described under “Fixed-Income Securities Risk.”
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
TBA Commitments Risk.Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and
40 | Janus Henderson Multi-Sector Income Fund

settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Emerging Markets Risk.Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets.
Currency Risk.Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment. As long as the Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. In addition, to the extent that the Fund uses forward currency exchange contracts, there is a risk that unanticipated changes in currency prices may negatively impact the Fund’s performance, among other things. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders in a taxable account.
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”), especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by
41 | Janus Henderson Multi-Sector Income Fund

various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
Collateralized Loan Obligation Risk.The risks of investing in collateralized loan obligations (“CLO”) include both the economic risks of the underlying loans combined with the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which the Fund is invested. Higher rated tranches (such as AAA rated tranches) do not constitute a guarantee, may be downgraded, and in stressed market environments it is possible that even senior CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. The Fund’s portfolio management may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are liquidity risk, interest rate risk, credit risk, prepayment risk, and the risk of default of the underlying asset, among others.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

The Adviser has contractually agreed to waive its investment advisory fee and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses) exceed 0.39%. In addition, the Adviser shall reimburse or waive out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees, payable by any share class so that such fees, in the aggregate, do not exceed 0.06% of a share class’ average daily net assets. The contractual waivers will remain in effect for at least a one-year period commencing on October 28, 2024. These contractual waivers may be terminated or modified only at the discretion of the Board of Trustees.
EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the first year and the Total Annual Fund Operating Expenses thereafter. Class C Shares automatically convert to Class A Shares

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 105% of the average value of its portfolio.
Principal investment strategies
The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in short- and intermediate-term securities such as corporate bonds or notes or government securities, including agency securities, commercial and residential mortgage-backed securities, and asset-backed securities. The Fund may invest in fixed and floating rate obligations with varying durations and credit risk transfer securities (“CRTs”). The Fund will invest at least 65% of its net assets in investment grade debt securities. The Fund may invest up to 35% of its net assets in high-yield bonds (also known as “junk” bonds). The Fund’s investments in short-term securities may include money market instruments. The Fund may enter into “to be announced” or “TBA” commitments when purchasing mortgage-backed securities or other securities, and may also invest in inflation-linked securities, including Treasury Inflation-Protected Securities, also known as TIPS. The Fund may also invest in securities that have contractual restrictions that prohibit or limit their public resale, which may include Rule 144A securities. The Fund may also invest in foreign securities. Due to the nature of the securities in which the Fund invests, it may have relatively high portfolio turnover compared to other funds.
The Fund’s average portfolio duration typically ranges between one and three years. As of June 30, 2024, the Fund’s average portfolio duration was 2.03 years.
Additionally, the Fund may invest its assets in derivatives. Derivative instruments have a value derived from, or directly linked to, an underlying asset, such as fixed-income securities, commodities, currencies, interest rates, or market indices. In particular, the Fund may use futures, including Treasury bond futures and interest rate swaps, to manage interest rate risk, yield curve positioning, and country exposure. The Fund may also use index credit default swaps for hedging purposes (to offset risks associated with an investment exposure, or market conditions), to increase or decrease the Fund’s exposure to a particular market, and to earn income, enhance returns, or preserve capital. The Fund’s exposure to derivatives will vary. For purposes of meeting its 80% investment policy, the Fund may include derivatives that have characteristics similar to the securities in which the Fund may directly invest. The Fund may engage in short sales of derivatives instruments.
Portfolio management’s investment process is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
47 | Janus Henderson Short Duration Flexible Bond Fund

As part of its investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors include corporate governance, company culture, exposure to climate change, and human capital management. To assess ESG Factors, portfolio management uses issuer reports, third-party data, and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio.
The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
Principal investment risks
The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. The principal risks associated with investing in the Fund are set forth below.
Market Risk.The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s net asset value may fluctuate and it may be more difficult to value or sell the Fund’s holdings. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.
Fixed-Income Securities Risk.Fixed-income securities are generally subject to the following risks:
Interest rate risk, which is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. Changing interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility.
Credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default.
Prepayment risk, which is the risk that, during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause the Fund to reinvest its assets in securities with lower yields, resulting in a decline in the Fund’s income or return potential.
Extension risk, which is the risk that, during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally anticipated, and as a result, the value of those obligations may fall.
Valuation risk, which is the risk that one or more of the fixed-income securities in which the Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer or the security.
Liquidity risk, which is the risk that fixed-income securities may be difficult or impossible to sell at the time that portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced).
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are considered speculative and may be more sensitive than other types of bonds to economic changes, political changes, or adverse developments specific to the company that issued the bond, which may adversely affect their value. High-yield bonds are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s Ratings Services, Fitch, Inc., and Moody’s Investors Service, Inc. or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
48 | Janus Henderson Short Duration Flexible Bond Fund

Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. The value of mortgage- and asset-backed securities will be influenced by factors affecting the real estate market and the assets underlying these securities. Investments in mortgage-and asset-backed securities may be subject to credit risk, valuation risk, liquidity risk, extension risk, and prepayment risk. These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn.
Credit Risk Transfer Securities Risk.CRTs are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as the Fund have no direct recourse to the underlying mortgage loans in the event of a default. The risks associated with CRTs are different from the risks associated with investments in mortgage-backed securities issued by government sponsored enterprises or private issuers because some or all of the mortgage default or credit risk associated with the underlying mortgage loans is transferred to investors. These risks are in addition to the risks described under “Fixed-Income Securities Risk.”
Foreign Exposure Risk.Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and net asset value may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio.
Sovereign Debt Risk.Investments in U.S. and non-U.S. government debt securities (“sovereign debt”) can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors including, but not limited to, its cash flow situation, the extent of its foreign currency reserves, the availability of foreign exchange when a payment is due, and the relative size of its debt position in relation to its economy as a whole. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent the Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
Floating Rate Obligations Risk.The Fund may invest in floating rate obligations with interest rates that reset regularly. The interest rates on floating rate obligations typically reset quarterly, although rates on some obligations may adjust at other intervals. Changes in the interest rates on floating rate obligations could result in lower income to the Fund. In addition, the secondary market on which floating rate obligations are traded may be less liquid than the market for investment grade securities or other types of income-producing securities, which may have an adverse impact on their market price. There is also a potential that there is no active market to trade floating rate obligations, that there may be restrictions on their transfer, or that the issuer may default. As a result, the Fund may be unable to sell floating rate obligations at the desired time or may be able to sell only at a price less than fair market value.
TBA Commitments Risk.Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, the Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to the Fund may be less favorable than expected. There is a risk that the security that the Fund buys will lose value between the purchase and settlement dates. TBA purchase and sales commitments may significantly increase the Fund’s portfolio turnover rate and are not included in the portfolio turnover rate calculation.
Inflation-Linked Investments Risk.Inflation-linked bonds (including TIPS), and other inflation-linked securities are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of these securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. The value of inflation-linked securities tends to react to changes in real interest rates. In general, the price of these securities can fall when real interest
49 | Janus Henderson Short Duration Flexible Bond Fund

rates rise, and can rise when real interest rates fall. Interest payments on these securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause the Fund to be more volatile than if it had not used leverage. Derivatives entail the risk that the counterparty may default on its payment obligations. If the counterparty to a derivative transaction defaults, the Fund may lose the net amount of the payments that it contractually is entitled to receive. Derivatives used for hedging purposes may reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by portfolio management or if the cost of the derivative outweighs the benefit of the hedge.
Short Exposure Risk.The Fund may enter into a derivatives transaction to obtain short investment exposure to the underlying reference asset. If the value of the underlying reference asset on which the Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes the Fund to credit risk, counterparty risk, and leverage risk.
Portfolio Turnover Risk.Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders in a taxable account.
Rule 144A Securities and Other Exempt Securities Risk.Investments in securities issued under Regulation S and Rule 144A and other securities exempt from certain registration requirements could have the effect of decreasing the Fund’s liquidity profile or preventing the Fund from disposing of them promptly at advantageous prices. Investments in securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available.
ESG Integration Risk.There is a risk that considering ESG Factors as part of the Fund’s investment process may fail to produce the intended results or that the Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. Information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop and may be incomplete or inaccurate, use different methodologies, or be applied differently across issuers and industries.
Securities Lending Risk.There is the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and the Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase replacement securities in the market. There is a risk that the value of the collateral could decrease below the cost of the replacement security by the time the replacement investment is made, resulting in a loss to the Fund.
Portfolio Management Risk.The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform benchmark indices or other funds with similar investment objectives.
An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund commenced operations on July 6, 2009. Class N Shares of the Fund commenced operations on May 31, 2012.
The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
50 | Janus Henderson Short Duration Flexible Bond Fund

The performance shown for Class A Shares, Class C Shares, Class S Shares, and Class I Shares for periods prior to July 6, 2009, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses of each respective share class, without the effect of any fee and expense limitations or waivers.
The performance shown for Class N Shares for periods prior to May 31, 2012, reflects the performance of the Fund’s Class T Shares, calculated using the fees and expenses of Class T Shares, net of any applicable fee and expense limitations or waivers.
If Class A Shares, Class C Shares, Class S Shares, and Class I Shares of the Fund had been available during periods prior to July 6, 2009, or Class N Shares of the Fund had been available during periods prior to May 31, 2012, the performance shown for each respective share class may have been different. The performance shown for the periods following the Fund’s commencement of Class A Shares, Class C Shares, Class S Shares, Class I Shares, and Class N Shares reflects the fees and expenses of each respective share class, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The bar chart figures do not include any applicable sales charges that an investor may pay when they buy or sell Class A Shares or Class C Shares of the Fund. If sales charges were included, the returns would be lower. The table compares the Fund’s average annual returns for the periods indicated to a broad-based securities market index, as well as to one or more supplemental indices that have investment characteristics similar to those of the Fund. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance (before and after taxes) does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Effective August 29, 2024, the Fund changed its broad-based securities market index from the Bloomberg 1-3 Year U.S. Government/Credit Index to the Bloomberg U.S. Aggregate Bond Index due to regulatory requirements. The Fund retained the Bloomberg 1-3 Year U.S. Government/Credit Index as a performance benchmark because the Bloomberg 1-3 Year U.S. Government/Credit Index is more closely aligned with the Fund’s investment strategies and investment restrictions.

Additional information about the Funds
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in each Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Shareholder Fees” are fees paid directly from your investment and may include sales loads.
“Annual Fund Operating Expenses” are paid out of a Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in each Fund Summary shows, these costs are borne indirectly by all shareholders.
The “Management Fee” is the investment advisory fee rate paid by each Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Distribution/Service (12b-1) Fees.” Because 12b-1 fees are charged as an ongoing fee, over time the fee will increase the cost of your investment and may cost you more than paying other types of sales charges. Distribution/Service (12b-1) Fees include a shareholder servicing fee of up to 0.25% for Class C Shares.
A contingent deferred sales charge of up to 1.00% may be imposed on certain redemptions of Class A Shares bought without an initial sales charge and then redeemed within 12 months of purchase. The contingent deferred sales charge is not reflected in the Example in each Fund Summary.
A contingent deferred sales charge of 1.00% generally applies on Class C Shares redeemed within 12 months of purchase. The contingent deferred sales charge may be waived for certain investors, as described in the Shareholder’s Guide.
“Other Expenses”
°
for Class A Shares, Class C Shares, and Class I Shares, may include administrative fees charged by intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds.
°
for Class S Shares, Class R Shares, and Class T Shares, include an administrative services fee of 0.25% of the average daily net assets of each class to compensate Janus Henderson Services US LLC (the “Transfer Agent”), the Funds’ transfer agent, for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of retirement plan participants, pension plan participants, or other underlying investors investing through institutional channels.
°
for all classes, include acquired fund fees and expenses, which are indirect expenses a Fund may incur as a result of investing in shares of an underlying fund, to the extent such expenses are less than 0.01%. “Acquired Fund” refers to any underlying fund (including, but not limited to, exchange-traded funds) in which a fund invests or has invested during the period. To the extent that a Fund invests in Acquired Funds, the Fund’s “Total Annual Fund Operating Expenses” may not correlate to the “Ratio of gross expenses to average net assets” presented in the Financial Highlights tables because that ratio includes only the direct operating expenses incurred by the Fund, not the indirect costs of investing in Acquired Funds. If applicable, or unless otherwise indicated in a Fund’s Fees and Expenses table, such amounts are less than 0.01%, and are included in the Fund’s “Other Expenses.”
°
for all classes, may include reimbursement to the Adviser of its out-of-pocket costs for services as administrator and to the Transfer Agent of its out-of-pocket costs for serving as transfer agent and providing, or arranging by others the provision of, servicing to shareholders.
°
include custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses.
The Adviser has contractually agreed to waive and/or reimburse each Fund’s “Total Annual Fund Operating Expenses” to certain limits for at least a one-year period commencing on October 28, 2024. The expense limits are described in the “Management Expenses” section of this Prospectus.
All expenses in a Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.

Additional investment strategies and general portfolio policies
The Funds’ Board of Trustees (“Trustees”) may change each Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. A Fund will notify you in writing at least 60 days before making any such change it considers material. To the extent that a Fund has an 80% investment policy, the Fund will provide shareholders with at least 60 days’ notice prior to changing this policy. If there is a material change to a Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that a Fund will achieve its investment objective.
Unless otherwise stated, the following section provides additional information about the investment strategies and general policies that are summarized in the Fund Summary sections, including the types of securities each Fund may invest in when pursuing its investment objective. This section also describes investment strategies and policies that the Funds may use to a lesser extent. These non-principal investment strategies and policies may become more important in the future since a Fund’s composition can change over time. Except for the Funds’ policies with respect to illiquid investments, borrowing, and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if a Fund exceeds a limit, other than illiquid investments, borrowing, and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. The “Glossary of Investment Terms” includes descriptions of investment terms used throughout the Prospectus.
Security Selection
Janus Henderson Absolute Return Income Opportunities Fund employs an “absolute return” strategy, which means that the Fund benchmarks itself to an index of cash instruments, rather than a fixed-income index. In pursuing this strategy, the Fund seeks to achieve positive returns that exceed its performance benchmark index in a variety of market environments. The Fund seeks value across sectors and geographies using a wide range of instruments to capitalize on investment opportunities to maximize current income, while at the same time seeking to provide low volatility. The Fund seeks to take advantage of market mispricings and dislocations caused by structural inefficiencies in the fixed-income market. For example, portfolio management may favor investments in smaller countries or regions that tend to be underrepresented in fixed-income indices that are more heavily focused on the United States or other larger regions globally. Portfolio management uses research which encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models. A position may be sold if it reaches its total return target, if the investment thesis for owning it changes, or to limit potential losses.
Portfolio management for Janus Henderson Developed World Bond Fund uses a process that combines a bottom-up approach to individual security selection rooted in thorough, independent research with a macro-economic overlay that determines appropriate country, asset sector, currency and industry exposure. In their bottom-up approach, portfolio management uses both qualitative and quantitative credit analysis to consider a variety of factors, including the issuer’s experience, managerial strength, debt service capability, operating outlook, sensitivity to economic conditions, current financial condition, liquidity and access to capital, asset protection, structural issues, covenant protection, and equity sponsorship. Portfolio management also works closely with a team of analysts to search for the most appropriate securities to include in the Fund’s portfolio.
The Fund will generally consider selling a security when, in portfolio management’s opinion, there is significant deterioration in company fundamentals, an inability to maintain open communication with management, a change in business strategy, a change in issuer-specific business outlook, realization of anticipated gains, or a failure by the issuer to meet operating/ financial targets. The Fund will also consider selling a security if, in portfolio management’s opinion, it no longer meets the environmental or social criteria noted above, or a superior investment opportunity arises.
Portfolio management’s investment process for Janus Henderson Flexible Bond Fund, Janus Henderson High-Yield Fund, Janus Henderson Multi-Sector Income Fund, and Janus Henderson Short Duration Flexible Bond Fund is research-driven, incorporating “top-down” and “bottom-up” factors to identify and manage exposure to risks across sectors, industries, and individual investments. Portfolio management evaluates expected risk-adjusted returns on a portfolio and position level by analyzing fundamentals, valuations, and market technical indicators. This research encompasses both traditional fundamental analysis and data driven quantitative models and signals from such models.
Unless the investment objective or policies prescribe otherwise, portfolio management may consider selling a security when, in portfolio management’s opinion, there is significant deterioration in company fundamentals, an inability to maintain open
56 | Janus Investment Fund

communication with management, a change in business strategy, a change in issuer-specific business outlook, realization of anticipated gains, or a failure by the issuer to meet operating/financial targets. A Fund may also consider selling a security if, in portfolio management’s opinion, a superior investment opportunity arises.
Cash Position
The Funds may not always stay fully invested. For example, when portfolio management believes that market conditions are unfavorable for investing, or when it is otherwise unable to locate attractive investment opportunities, a Fund’s cash or similar investments may increase. Due to differing investment strategies, the cash positions among the Funds may vary significantly. When a Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent a Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.
In addition, a Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. A Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under unusual circumstances such as these, a Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.
Commodity Futures Trading Commission (“CFTC”) Regulation
The operation of Janus Henderson Absolute Return Income Opportunities Fund is subject to certain CFTC rules and regulations. Existing or new CFTC regulation may increase the costs of implementing the Fund’s strategies, which could negatively affect the Fund’s returns.
Derivatives
A Fund may invest in derivatives, which are financial instruments whose value is derived from, or directly linked to, an underlying asset, instrument, currency, or index. A Fund may take long and short positions in derivatives. Derivatives can be used for hedging purposes or for non-hedging purposes, such as seeking to earn income and enhance return, to protect unrealized gains, or to avoid realizing losses. Such techniques may also be used to adjust currency exposure relative to a benchmark index, to gain exposure to the market pending investment of cash balances, or to meet liquidity needs.
Emerging Markets
Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Indexsm. For Janus Henderson Flexible Bond Fund and Janus Henderson Multi-Sector Income Fund, such countries consist of countries included in the International Monetary Fund list of Emerging and Developing Economies and/or any country that is included in the MSCI Emerging Markets Index, which measures the equity market performance of developing markets. Emerging market countries in which a Fund may invest include frontier market countries, the economies of which are less developed than other emerging market countries. Frontier market countries typically are located in the Asia-Pacific region, Central and Eastern Europe, the Middle East, Central and South America, and Africa.
ESG Investments and Integration
As part of a Fund’s investment process, portfolio management considers environmental, social, and governance (“ESG”) risks and opportunities (“ESG Factors”) that it believes are financially material, alongside other fundamental investment factors. Examples of potential financially material ESG Factors may include corporate governance, political governance, executive pay, board structure and diversity, business ethics, corporate reporting, company culture, human capital management and diversity, community relations, human rights, exposure to climate change, biodiversity, and deforestation. Portfolio management focuses on the ESG Factors it considers most likely to have a material impact on the long-term financial performance of the issuer, which includes identifying ESG Factors attributable to a particular region, sector, industry, or issuer. To facilitate its assessment of ESG Factors, portfolio management uses issuer reports, third-party data and internally-generated analyses and may engage directly with issuers. ESG Factors are one of many considerations in the investment decision-making process and may not be determinative in deciding to include or exclude an investment from the portfolio. Portfolio management may assess the relevance of ESG Factors to its fundamental research process differently across issuers, sectors, regions, and asset classes.
57 | Janus Investment Fund

Portfolio management of Janus Henderson Developed World Bond Fund also seeks to (i) avoid corporate issuers that are significantly engaged in business activities that they believe may be environmentally and/or socially harmful, as discussed below; (ii) invest in a portfolio of corporate issuers that, in the aggregate, has a lower carbon intensity and/or footprint than the ICE BofA Global Corporate & High Yield Index on a monthly basis; (iii) avoid sovereign bond issuers that (a) have been sanctioned by the European Union or United Nations or have insufficient rankings with respect to political rights and civil liberties, as measured by third-party inputs, or (b) have not ratified the Paris Climate Accord.
Additionally, portfolio management applies broad-based negative screens, which incorporate third-party inputs, to seek to avoid securities of issuers that derive more than de minimis revenue from certain activities considered by portfolio management to be environmentally and/or socially harmful. A current list of such business activities, which may evolve over time, follows:
oil and gas generation and production;
oil sands extraction;
shale energy extraction;
thermal coal extraction and power generation;
Arctic oil and gas extraction;
tobacco;
fur;
adult entertainment;
gambling or controversial weapons; and
United Nations Global Compact violators.
The Fund does not apply the avoidance criteria noted above in managing the Fund’s exposure to cash and cash equivalents, U.S. Treasuries, and credit default swaps on indices.
Eurodollar Futures Contracts
Certain Funds may make investments in Eurodollar futures contracts, which are typically used to adjust interest rate exposure and replicate government bond positions. Eurodollar futures contracts are U.S. dollar-denominated futures contracts that are based on a reference rate. Eurodollar futures contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings.
Exchange-Traded Funds
Certain Funds may invest in exchange-traded funds (“ETFs”), including affiliated ETFs, to gain exposure to a particular portion of the market. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of a Fund, which will be indirectly paid by such Fund. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. A Fund is also subject to the risks associated with the securities in which the ETF invests.
Foreign Securities
A Fund may invest in foreign securities and/or foreign currencies. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located. Foreign securities are generally selected on a security-by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. The Funds may at times have significant foreign exposure, including exposure to emerging markets.
High-Yield Bonds
Within the parameters of their specific investment policies, certain Funds may invest in bonds that are rated below investment grade (also known as “junk” bonds), such as BB+ or lower by Standard & Poor’s Ratings Services (“Standard & Poor’s”) and Fitch, Inc. (“Fitch”), or Ba1 or lower by Moody’s Investors Service, Inc. (“Moody’s”), or is an unrated bond of similar quality. A Fund may also invest in unrated bonds of foreign and domestic issuers.
58 | Janus Investment Fund

Illiquid Investments
A Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.
Inflation-Linked Securities
Certain Funds may invest in inflation-linked securities, including Treasury Inflation-Protected Securities (also known as TIPS), municipal inflation-indexed bonds and corporate inflation-indexed bonds, or in derivatives that are linked to these securities. TIPS are inflation-linked bonds issued by the U.S. Government. Inflation-linked bonds may also be issued by, or related to, sovereign governments of other developed countries, emerging market countries, or companies or other entities not affiliated with governments.
Inflation-linked bonds are fixed-income securities whose interest and principal payments are periodically adjusted according to the rate of inflation. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the consumer price index. If an index measuring inflation falls, the principal value of inflation-indexed bonds will typically be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Because of their inflation adjustment feature, inflation-linked bonds typically have lower yields than conventional fixed-rate bonds.
Inflation-linked bonds normally decline in price when real interest rates rise. In the event of deflation, when prices decline over time, the principal and income of inflation-linked bonds would likely decline, resulting in losses to a Fund.
In the case of TIPS, repayment of original bond principal upon maturity (as adjusted for inflation) is guaranteed. When TIPS mature, the holder is paid the adjusted principal or original principal, whichever is greater. For inflation-linked bonds that do not provide a similar guarantee, the adjusted principal value or maturity amount of the inflation-linked bond repaid at maturity may be less than the original principal.
Leverage
Certain of a Fund’s investments, including derivatives and short sale transactions, involve the use of leverage. Leverage is investment exposure which exceeds the initial amount invested. Leverage occurs when a Fund increases its assets available for investment using derivatives, short sales, when-issued, delayed delivery, or forward commitment transactions, or other similar transactions. The use of other investment techniques can also create a leveraging effect on a Fund.
Loans
The Funds may invest in various commercial loans, including bank loans, bridge loans, debtor-in-possession (“DIP”) loans, mezzanine loans, and other fixed and floating rate loans. These loans may be acquired through loan participations and assignments or on a when-issued basis.
Bank Loans.Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. A Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities.
Bridge Loans.Bridge loans are short-term loan arrangements typically made by a borrower in anticipation of receiving intermediate-term or long-term permanent financing. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan increases the longer the loan remains outstanding. In addition, bridge loans commonly contain a conversion feature that allows the bridge loan investor to convert its loan interest to senior exchange notes if the loan has not been prepaid in full on or prior to its maturity date. Bridge loans typically are structured as senior loans, but may be structured as junior loans.
DIP Loans.DIP loans are issued in connection with restructuring and refinancing transactions. DIP loans are loans to a debtor-in-possession in a proceeding under the U.S. bankruptcy code that have been approved by the bankruptcy court. DIP loans are typically fully secured by a lien on the debtor’s otherwise unencumbered assets or secured by a junior lien on the debtor’s encumbered assets (so long as the loan is fully secured based on the most recent current valuation or appraisal report of the debtor). DIP loans are often required to close with certainty and in a rapid manner to satisfy existing creditors and to enable the issuer to emerge from bankruptcy or to avoid a bankruptcy proceeding.
59 | Janus Investment Fund

Mezzanine Loans.Mezzanine loans are a hybrid of debt and equity financing that is typically used to fund the expansion of existing companies. A mezzanine loan is composed of debt capital that gives the lender the right to convert to an ownership or equity interest in the company if the loan is not paid back in time and in full. Mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure.
Mortgage- and Asset-Backed Securities
A Fund may purchase fixed or variable rate commercial or residential mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees are backed by the full faith and credit of the U.S. Government, which means that the U.S. Government guarantees that the interest and principal will be paid when due. Fannie Mae and Freddie Mac securities, as well as the securities of other government or government-related entities, are not backed by the full faith and credit of the U.S. Government.
A Fund may also purchase mortgage- and asset-backed securities through single- and multi-seller conduits, collateralized mortgage obligations, collateralized loan obligations, collateralized bond obligations, structured investment vehicles, and other similar securities. Asset-backed securities may be backed by various consumer obligations, including automobile loans, equipment leases, credit card receivables, or other collateral. In the event the underlying loans are not paid, the securities’ issuer could be forced to sell the assets and recognize losses on such assets, which could impact a Fund’s yield and return.
Non-Agency Mortgage-Backed Securities
A Fund may invest in non-agency mortgage-backed securities, which are mortgage-backed securities issued or guaranteed by private issuers.
Options on Futures Contracts
An option on a futures contract gives the buyer the right, but not the obligation, to buy or sell a futures contract at a specified price on or before a specified date. Futures contracts and options on futures are standardized and traded on designated exchanges. To the extent a Fund engages in futures contracts on foreign exchanges, such exchanges may not provide the same protection as U.S. exchanges.
Options on Securities and Indices
A Fund may purchase and write put and call options on securities and indices. A put option on a security gives the purchaser of the option the right to sell, and the writer of the option the obligation to buy, the underlying security at any time during the option period. A call option on a security gives the purchaser of the option the right to buy, and the writer of the option the obligation to sell, the underlying security at any time during the option period. The premium paid to the writer is the consideration for undertaking the obligations under the option contract.
Put and call options on indices are similar to options on securities except that options on an index give the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the underlying index is greater than (or less than, in the case of puts) the exercise price of the option. This amount of cash is equal to the difference between the closing price of the index and the exercise price of the option, expressed in dollars multiplied by a specified number. Thus, unlike options on individual securities, all settlements are in cash, and gain or loss depends on price movements in the particular market represented by the index generally, rather than the price movements in individual securities. All options written on indices or securities must be “covered” as required by the Investment Company Act of 1940, as amended.
Options on Swap Contracts
A Fund may enter into options on swap agreements, commonly referred to as “swaptions.” A swaption is a contract that gives a purchaser the right, but not the obligation, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement, at some designated future time on specified terms. Swaptions can be used for a variety of purposes, including to manage a Fund’s overall exposure to changes in interest or foreign currency exchange rates and credit quality; as an efficient means of adjusting a Fund’s exposure to certain markets; in an effort to enhance income or total return or protect the value of portfolio securities; to serve as a cash management tool; and to adjust portfolio duration or credit risk.
Portfolio Turnover
Portfolio turnover rates are generally not a factor in making buy and sell decisions for the Funds. Changes may be made to a Fund’s portfolio, consistent with the Fund’s investment objective and policies, when portfolio management believes such changes are in the best interests of the Fund and its shareholders. Short-term transactions may result from the purchase of a security in anticipation of relatively short-term gains, liquidity needs, securities having reached a price or yield objective,
60 | Janus Investment Fund

changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. A Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of a Fund (including due to shareholder purchases and redemptions), the nature of a Fund’s investments, and the investment style of portfolio management. Changes are normally made in a Fund’s portfolio whenever portfolio management believes such changes are desirable. Due to the nature of the securities in which they invest, the Funds may have relatively high portfolio turnover compared to other funds.
Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in the acceleration of taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on a Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Funds’ historical turnover rates.
REITs and Real Estate-Related Securities
Each Fund may invest in equity and debt securities of real estate-related companies. These securities may include common stocks, preferred stocks, and other securities, including, but not limited to, mortgage-backed securities, real estate-backed securities, securities of real estate investment trusts (“REITs”) and similar REIT-like entities (such as real estate operating companies (“REOCs”)). A REIT is an entity that invests in real estate-related projects, such as properties, mortgage loans, and construction loans. REITs are often categorized as equity REITs, mortgage REITs, and hybrid REITs. An equity REIT, the most common type of REIT, invests primarily in the fee ownership of land and buildings. An equity REIT derives its income primarily from rental income but may also realize capital gains or losses by selling real estate properties in its portfolio that have appreciated or depreciated in value. A mortgage REIT invests primarily in mortgages on real estate, which may secure construction, development, or long-term loans. A mortgage REIT generally derives its income from interest payments on the credit it has extended. A hybrid REIT combines the characteristics of equity REITs and mortgage REITs, generally by holding both ownership interests and mortgage interests in real estate.
Similar to REITs, REOCs are publicly-traded real estate companies that typically engage in the development, management or financing of real estate, such as homebuilders, hotel management companies, land developers and brokers. REOCs, however, have not elected (or are not eligible) to be taxed as a REIT. The reasons for not making such an election include the (i) availability of tax-loss carry-forwards, (ii) operation in non-REIT-qualifying lines of business, and (iii) ability to retain earnings. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code of 1986, as amended, and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations and more flexibility in terms of the real estate investments they can make.
Securities Lending
A Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When a Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. A Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. It is also possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, a Fund may lose money. There is also the risk that when portfolio securities are lent, the securities may not be returned on a timely basis, and a Fund may experience delays and costs in recovering the security or gaining access to the collateral provided to the Fund to collateralize the loan. If a Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to a Fund. In certain circumstances, individual loan transactions could yield negative returns. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.
Short Sales
The Funds may invest in short positions through short sales of stocks and structured products, and through derivatives that include swaps, uncovered written calls, and futures. A Fund may also engage in short sales “against the box” and options for hedging purposes. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to

obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility.
A short sale is generally a transaction in which a Fund sells a security it does not own or have the right to acquire (or that it owns but does not wish to deliver) in anticipation that the market price of that security will decline. To complete the transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. A short sale is subject to the risk that if the price of the security sold short increases in value, the Fund will incur a loss because it will have to replace the security sold short by purchasing it at a higher price. In addition, the Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the borrowed securities be returned to the lender on short notice, and the Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, a “short squeeze” can occur, which means that the demand is greater than the supply for the stock sold short. If a short squeeze occurs, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale. Because there is no upper limit to the price a borrowed security may reach prior to closing a short position, a Fund’s losses are potentially unlimited in a short sale transaction. A Fund’s gains and losses will also be decreased or increased, as the case may be, by the amount of any dividends, interest, or expenses, including transaction costs and borrowing fees, the Fund may be required to pay in connection with a short sale. Such payments may result in the Fund having higher expenses than a fund that does not engage in short sales and may negatively affect the Fund’s performance.
A Fund may enter into a derivatives transaction to obtain short investment exposure to an underlying reference asset. If the value of the underlying reference asset on which a Fund has obtained a short investment exposure increases, the Fund will incur a loss. This potential loss is theoretically unlimited. A short exposure through a derivative also exposes a Fund to credit risk, counterparty risk, and leverage risk.
Sovereign Bond Futures Contracts
Sovereign bond futures contracts provide for the delivery upon maturity of one sovereign bond among a basket of eligible-to-deliver sovereign bonds.
Special Situations
The Funds may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of portfolio management, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure. Investments in “special situations” companies can present greater risks than investments in companies not experiencing special situations, and a Fund’s performance could be adversely impacted if the securities selected decline in value or fail to appreciate in value.
Swap Agreements
Certain Funds may utilize swap agreements including, but not limited to, credit default swaps, equity swaps, inflation index swaps, inflation-linked swaps, interest rate and currency swaps, total return swaps (including fixed-income total return swaps), and swaps on exchange-traded funds, as a means to gain exposure to certain companies or countries, a commodity index, or commodity markets, and/or to “hedge” or protect their portfolios from adverse movements in securities prices, the rate of inflation, or interest rates. Swaps may also be used for capital appreciation. Swap agreements are two-party contracts to exchange one set of cash flows for another. Swap agreements entail the risk that a party will default on its payment obligations to a Fund. If the other party to a swap defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. If a Fund utilizes a swap at the wrong time or judges market conditions incorrectly,
62 | Janus Investment Fund

the swap may result in a loss to the Fund and reduce the Fund’s total return. Various types of swaps such as credit default, equity, interest rate, currency, inflation index, and total return are described in this Prospectus and/or in the “Glossary of Investment Terms.”
Cross-Currency Swaps.Certain Funds may enter into cross-currency swaps or basis swaps. A cross-currency swap involves the exchange of payments denominated in one currency for payments denominated in another. Payments are based on a notional principal amount, the value of which is fixed in exchange rate terms at the swap’s inception.
Index Credit Default Swaps.Certain Funds may invest in index credit default swaps (“CDX”). CDX are swaps on an index of credit default swaps. CDX allow an investor to manage credit risk or take a position on a basket of credit entities (such as credit default swaps or a commercial mortgage-backed index) in a more efficient manner than transacting in a single-name credit default swap. If a credit event occurs in one of the underlying companies, the protection is paid out via the delivery of the defaulted bond by the buyer of protection in return for a payment of notional value of the defaulted bond by the seller of protection or it may be settled through a cash settlement between the two parties. The underlying company is then removed from the index. New series of CDX are issued on a regular basis.
Commercial mortgage-backed securities index swaps (“CMBX”) are a type of index credit default swap that are made up of tranches of commercial mortgage-backed securities rather than credit default swaps. CMBX involve a pay-as-you go settlement process designed to capture non-default events that affect the cash flow to the underlying mortgage-backed securities tranche.
Interest Rate Swaps.Certain Funds may enter into interest rate swaps, which involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments). Interest rate swaps are generally entered into on a net basis. Interest rate swaps do not involve the delivery of securities, other underlying assets, or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that certain Funds are contractually obligated to make.
Single-Name Credit Default Swaps.A Fund may invest in single-name credit default swaps (“CDS”) to buy or sell credit protection to hedge its credit exposure, gain issuer exposure without owning the underlying security, or increase the Fund’s total return. CDS are a specific kind of counterparty agreement that allow the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the CDS agrees to insure this risk in exchange for regular periodic payments.
TBA Commitments
A Fund may enter into “to be announced” or “TBA” commitments. TBA commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining a Fund’s net asset value. Because a Fund is generally not required to pay for the security until the settlement date, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
Treasury Futures Contracts
Treasury futures contracts, which are exchange-traded, are typically used to obtain interest rate exposure in order to manage duration. A Treasury futures contract is a bilateral agreement where one party agrees to accept and the other party agrees to make delivery of a U.S. Treasury security, as called for in the agreement at a specified date and at an agreed upon price. Generally, Treasury futures contracts are closed out or rolled over prior to their expiration date.
U.S. Government Securities
The Funds may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer. For securities not backed by the full faith and credit of the United States, a Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of
63 | Janus Investment Fund

loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets.
Other Types of Investments
Unless otherwise stated within its specific investment policies, each Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Funds. If successful, they may benefit the Funds by earning a return on the Funds’ assets or reducing risk; however, they may not achieve the Funds’ investment objectives. These securities and strategies may include:
equity securities (such as stocks or any other security representing an ownership interest)
preferred stocks and securities convertible into common stocks or preferred stocks
pass-through securities including commercial and residential mortgage- and asset-backed securities and mortgage dollar rolls
zero coupon, pay-in-kind, and step coupon securities
securities purchased on a when-issued, delayed delivery, or forward commitment basis
equity and fixed-income securities issued in private placement transactions
Risks of the Funds
The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Funds. The Funds invest substantially all of their assets in fixed-income securities or income-generating securities and, to varying degrees, derivatives. The following information is intended to help you better understand some of the risks of investing in the Funds, including those risks that are summarized in the Fund Summary sections. This information also includes descriptions of other risks a Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on a Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in a Fund, you should consider carefully the risks that you assume when investing in the Fund.
Collateralized Loan Obligation Risk.The risks of investing in a collateralized loan obligation (“CLO”) can be generally summarized as a combination of economic risks of the underlying loans and the risks associated with the CLO structure governing the priority of payments. The degree of such risk will generally correspond to the specific tranche in which a Fund is invested. Higher rated tranches (such as AAA rated tranches) do not constitute a guarantee and in stressed market environments it is possible that these CLO tranches could experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and the disappearance of the subordinated/equity tranches, market anticipation of defaults, as well as negative market sentiment with respect to CLO securities as an asset class. A Fund’s portfolio management may not be able to accurately predict how specific CLOs or the portfolio of underlying loans for such CLOs will react to changes or stresses in the market, including changes in interest rates. The most common risks associated with investing in CLOs are interest rate risk, credit risk, liquidity risk, prepayment risk, and the risk of default of the underlying asset, among others.
Collateralized Mortgage Obligation Risk.Collateralized mortgage obligations (“CMOs”) are a type of mortgage-backed security. CMOs are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams (tranches) with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches may represent a right to receive interest only (“IOs”), principal only (“POs”) or an amount that remains after floating-rate tranches are paid (an inverse floater). These securities are frequently referred to as “mortgage derivatives” and may be extremely sensitive to changes in interest rates. Interest rates on inverse floaters, for example, vary inversely with a short-term floating rate (which may be reset periodically). Interest rates on inverse floaters will decrease when short-term rates increase, and will increase when short-term rates decrease. These securities have the effect of providing a degree of investment leverage. In response to changes in market interest rates or other market conditions, the value of an inverse floater may increase or decrease at a multiple of the increase or decrease in the value of the underlying securities. If a Fund invests
64 | Janus Investment Fund

in CMO tranches (including CMO tranches issued by government agencies) and interest rates move in a manner not anticipated by the Adviser, it is possible that the Fund could lose all or substantially all of its investment.
Convertible Securities Risk.A Fund may invest in securities that are convertible into preferred and common stocks, and thus, is subject to the risks of investments in both debt and equity securities. The market value of convertible securities tends to decline as interest rates increase and, conversely, tends to increase as interest rates decline. In addition, because of the conversion feature, the market value of convertible securities tends to vary with fluctuations in the market value of the underlying preferred and common stocks and, therefore, also will react to variations in the general market for equity securities.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to a Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to a Fund. A Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. A Fund may be exposed to counterparty risk to the extent it participates in lending its securities to third parties and/or cash sweep arrangements whereby the Fund’s cash balance is invested in one or more types of cash management vehicles or in time deposits. In addition, a Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements, debt securities, and derivatives (including various types of forwards, swaps, futures, and options). Each Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that a Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.Through a Fund’s investments in fixed-income securities, a Fund is subject to the risks associated with the credit quality of the issuers of those fixed-income securities. Credit quality measures the likelihood that the issuer or borrower will meet its obligations on a bond. One of the fundamental risks is credit risk, which is the risk that an issuer will be unable to make principal and interest payments when due, or default on its obligations. Higher credit risk may negatively impact a Fund’s returns and yield.
Many fixed-income securities receive credit ratings from services such as Standard & Poor’s, Fitch, and Moody’s. These services assign ratings to securities by assessing the likelihood of issuer default. The lower a bond issue is rated by an agency, the more credit risk it is considered to represent. Lower rated instruments and securities generally pay interest at a higher rate to compensate for the associated greater risk. Interest rates can fluctuate in response to economic or market conditions, which can result in a fluctuation in the price of a security and impact a Fund’s return and yield. If a security has not received a rating, a Fund must rely upon the Adviser’s credit assessment, which if incorrect can also impact the Fund’s returns and yield. Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Derivatives Risk.Derivatives can be volatile and involve risks in addition to the risks of the underlying referenced securities or asset. Gains or losses from a derivative investment can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Leverage may cause a Fund to be more volatile than if it had not used leverage.
The Funds may use short sales, futures, options, swap agreements (including, but not limited to, equity, interest rate, credit default, and total return), and other derivative instruments individually or in combination to “hedge” or protect their portfolios from adverse movements in securities prices and interest rates. The Funds may also use a variety of currency hedging techniques, including the use of forward currency contracts, to manage currency risk or may use futures contracts on securities indices to gain exposure to equity securities. There is no guarantee that portfolio management’s use of derivative investments will benefit the Funds. A Fund’s performance could be worse than if the Fund had not used such instruments. Use of such investments may instead increase risk to the Fund, rather than reduce risk. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by a Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. To the extent a Fund enters into short derivative positions, a Fund may be exposed to risks similar to those associated with short sales, including the risk that a Fund’s losses are theoretically unlimited.
65 | Janus Investment Fund

Cross-Currency Swaps Risk.Cross-currency or basis swaps are subject to currency risk. They also involve exchange risk on principal and are subject to credit risk.
Currency Futures Risk.Currency futures are similar to forward foreign currency exchange contracts, and pose similar risks, except that futures contracts are standardized, exchange-traded contracts while forward foreign currency exchange contracts are traded in the over-the-counter market. The use of currency futures contracts may substantially change a Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as anticipated. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns. Currency futures may also involve leverage risk.
Eurodollar Futures Contracts Risk.Eurodollar futures contracts involve market risk associated with changes in interest rates.
Forward Foreign Currency Exchange Contract Risk.Forward foreign currency exchange contracts (“forward currency contracts”) involve the risk that unanticipated changes in currency prices may negatively impact a Fund’s performance. Moreover, there may be an imperfect correlation between a Fund’s portfolio holdings of securities quoted or denominated in a particular currency and any forward currency contracts entered into by the Fund, which will expose the Fund to risk of foreign exchange loss. The trading markets for forward currency contracts offer less protection against defaults than trading in currency instruments on an exchange. Because a forward currency contract is not guaranteed by an exchange or clearinghouse, a default on the contract could result in losses to a Fund and may force the Fund to cover its purchase or sale commitments, if any, at the current market price. In addition, forward currency contract markets can experience periods of illiquidity, which could prevent a Fund from divesting of a forward currency contract at the optimal time and may adversely affect a Fund’s returns and net asset value.
Futures and Swaps Related to Interest Rate Risk.A Fund’s investments in interest rate futures, swaps, or futures on interest rate sensitive securities entail the risk that portfolio management’s prediction of the direction of interest rates is wrong, and the Fund could incur a loss. In addition, due to the possibility of price distortions in the interest rate futures or swaps markets, or an imperfect correlation between the underlying instrument and the interest rate portfolio management is seeking to hedge, a correct forecast of general interest rate trends by portfolio management may not result in the successful use of futures and swaps related to interest rates.
Index Credit Default Swaps Risk.If a Fund holds a long position in CDX, the Fund would indirectly bear its proportionate share of any expenses paid by CDX. By investing in CDX, a Fund could be exposed to illiquidity risk, counterparty risk, and credit risk of the issuers of the underlying loan obligations and of the CDX markets. If there is a default by the CDX counterparty, a Fund will have contractual remedies pursuant to the agreements related to the transaction. CDX also bear the risk that a Fund will not be able to meet its obligation to the counterparty.
Options on Futures Contracts Risk.The amount of risk that a Fund assumes when it purchases an option on a futures contract is the premium paid for the option, plus related transaction costs. In order to profit from an option purchased, it may be necessary to exercise the option and to liquidate the underlying futures contract subject to the risks of the availability of a liquid offset market. The seller of an option on a futures contract is subject to the risks of commodity futures trading, including the requirement of initial and variation margin payments, as well as the additional risk that movements in the price of the option may not correlate with movements in the price underlying security, index, currency, or futures contracts.
Options on Securities and Indices Risk.Options on securities may be subject to greater fluctuations in value than an investment in the underlying securities. If a Fund is unable to effect a closing purchase transaction with respect to covered options it has written, the Fund will not be able to sell the underlying securities or dispose of assets held in a segregated account until the options expire or are exercised. Similarly, if the Fund is unable to effect a closing sale transaction with respect to options it has purchased, it will have to exercise the options in order to realize any profit and will incur transaction costs upon the purchase or sale of underlying securities.
Options on indices may, depending on circumstances, involve greater risk than options on securities. Because index options are settled in cash, when a Fund writes a call on an index it may not be able to provide in advance for its potential settlement obligations by acquiring and holding the underlying securities.
Options on Swap Contracts Risk.Because the use of options on swap contracts, or “swaptions,” generally does not involve the delivery of securities or other underlying assets or principal, the risk of loss with respect to swaptions generally is
66 | Janus Investment Fund

limited to the net amount of payments that a Fund is contractually obligated to make. There is also a risk of a default by the other party to a swaption, in which case the Fund may not receive the net amount of payments that it contractually is entitled to receive. Entering into a swaption contract involves, to varying degrees, the elements of credit, market, and interest rate risk, associated with both option contracts and swap contracts.
Single-Name Credit Default Swaps Risk.When a Fund buys a single-name CDS, the Fund will receive a return on its investment only in the event of a credit event, such as default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). If a single-name CDS transaction is particularly large, or if the relevant market is illiquid, it may not be possible for the Fund to initiate a single-name CDS transaction or to liquidate its position at an advantageous time or price, which may result in significant losses. Moreover, the Fund bears the risk of loss of the amount expected to be received under a single-name CDS in the event of the default or bankruptcy of the counterparty. The risks associated with cleared single-name CDS may be lower than that for uncleared single-name CDS because for cleared single-name CDS, the counterparty is a clearinghouse (to the extent such a trading market is available). However, there can be no assurance that a clearinghouse or its members will satisfy their obligations to the Fund. Unlike CDX, single-name CDS do not have the benefit of diversification across many issuers.
Sovereign Bond Futures Contracts Risk.Interest rate movements directly affect the price of the sovereign bond futures contracts held by a Fund. If a sovereign bond futures contract is denominated in a non-U.S. currency, a Fund will be exposed to exchange rate risk. In addition, the price, yield, and modified duration of each eligible-to-deliver sovereign bond under the relevant sovereign bond futures contract may change unpredictably, affecting the value of the sovereign bond futures contract.
Treasury Futures Contracts Risk.While transactions in Treasury futures contracts may reduce certain risks, unanticipated changes in interest rates or securities prices may result in a poorer overall performance for a Fund than if it had not entered into any Treasury futures contracts. To the extent a Fund uses Treasury futures contracts, it is exposed to additional volatility and potential losses resulting from leverage. Losses (or gains) involving Treasury futures contracts can sometimes be substantial – in part because a relatively small price movement in a Treasury futures contract may result in an immediate and substantial loss (or gain) for a Fund.
Emerging Markets Risk.Within the parameters of its specific investment policies, each Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries include, but are not limited to, countries included in the MSCI Emerging Markets Index. For Janus Henderson Flexible Bond Fund and Janus Henderson Multi-Sector Income Fund, such countries consist of countries included in the International Monetary Fund list of Emerging and Developing Economies and/or any country that is included in the MSCI Emerging Markets Index, which measures the equity market performance of developing markets. To the extent that a Fund invests a significant amount of its assets in one or more of these countries, its returns and net asset value may be affected to a large degree by events and economic conditions in such countries. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on a Fund’s investments.
The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for a Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, a Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that a Fund invests a significant portion of its assets in the securities of emerging markets issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region, which could have a negative impact on the Fund’s performance. A Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.
67 | Janus Investment Fund

Emerging market countries in which a Fund may invest include frontier market countries, which generally have smaller economies and even less developed capital markets than traditional developing markets, and as a result, the risks of investing in developing market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by other countries; and the relatively new and unsettled securities laws in many frontier market countries.
ESG Integration and Investment Risk.There is a risk that considering ESG Factors as part of a Fund’s investment process may fail to produce the intended results or that a Fund may perform differently from funds that have a similar investment style but do not formally incorporate such considerations in their strategy. While portfolio management believes that the consideration of financially material ESG Factors has the potential to provide better risk-adjusted returns, ESG Factors may not be considered for every investment decision and there is no guarantee that the consideration of ESG Factors will result in better performance. In addition, information related to ESG Factors provided by issuers and third parties, upon which portfolio management may utilize, continues to develop, and may be incomplete, inaccurate, use different methodologies or be applied differently across issuers and industries. Further, the U.S. regulatory landscape regarding the use of ESG Factors in investing is still developing and future rules and regulations may require a Fund to modify or alter its investment process and/or how it discloses its consideration of ESG Factors.
Janus Henderson Developed World Bond Fund may employ exclusionary criteria to avoid investing in certain industries, activities, or assets considered by portfolio management to have a negative impact on society or the environment. This Fund is subject to similar risks as those Funds that consider ESG Factors as part of their investment process.
European Investments Risk.Exposure to investments in European countries may expose a Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. A Fund may be exposed to investments in securities of issuers that are domiciled in, have significant operations in, or that are listed on at least one securities exchange within member states of the European Union (the “EU”). A number of countries within the EU are also members of the Economic and Monetary Union (the “EMU”) (the “eurozone”) and have adopted the euro as their currency. Eurozone membership requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in import or export tariffs, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and other currencies of certain EU countries which are not in the eurozone, the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of other EU member states and major trading partners outside Europe.
Exchange-Traded Funds Risk.ETFs are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its net asset value. When a Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in a Fund may be higher than the cost of investing directly in ETFs and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, a Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities.
The ETFs in which a Fund invests are subject to specific risks, depending on the investment strategy of the ETF. In turn, a Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because a Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk. To the extent a Fund invests in fixed-income ETFs, it will be indirectly exposed to the same risks described under “Fixed-Income Securities Risk.”
68 | Janus Investment Fund

Exchange-Traded Notes Risk.Exchange-traded notes (“ETNs”) are debt securities whose returns are linked to a particular index. ETNs are typically linked to the performance of a commodities index that reflects the potential return on unleveraged investments in futures contracts of physical commodities, plus a specified rate of interest that could be earned on cash collateral. ETNs are subject to credit risk and counterparty risk. The value of an ETN may vary and may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events that affect the referenced commodity. When a Fund invests in ETNs it will bear its proportionate share of any fees and expenses borne by the ETN. There may be restrictions on a Fund’s right to redeem its investment in an ETN, which is meant to be held until maturity. A Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market.
Fixed-Income Securities Risk.Each Fund invests in a variety of fixed-income securities. Typically, the values of fixed-income securities change inversely with prevailing interest rates. Therefore, a fundamental risk of fixed-income securities is interest rate risk, which is the risk that the value of such securities will generally decline as prevailing interest rates rise, which may cause a Fund’s net asset value to likewise decrease. How specific fixed-income securities may react to changes in interest rates will depend on the specific characteristics of each security. For example, while securities with longer maturities and durations tend to produce higher yields, they also tend to be more sensitive to changes in prevailing interest rates and are therefore more volatile than shorter-term securities and are subject to greater market fluctuations as a result of changes in interest rates. However, calculations of maturity and duration may be based on estimates and may not reliably predict a security’s price sensitivity to changes in interest rates. In addition, different interest rate measures (such as short- and long-term interest rates and U.S. and non-U.S. interest rates), or interest rates on different types of securities or securities of different issuers, may not necessarily change in the same amount or in the same direction. Investments in fixed-income securities with very low or negative interest rates may diminish a Fund’s yield and performance.
Fixed-income securities are also subject to credit risk, which is the risk that the credit strength of an issuer of a fixed-income security will weaken and/or that the issuer will be unable to make timely principal and interest payments and that the security may go into default. In addition, there is prepayment risk, which is the risk that during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated, which may cause a Fund to reinvest its assets in securities with lower yields, resulting in a decline in a Fund’s income or return potential. Fixed-income securities may also be subject to valuation risk and liquidity risk. Valuation risk is the risk that one or more of the fixed-income securities in which a Fund invests are priced differently than the value realized upon such security’s sale. In times of market instability, valuation may be more difficult. Valuation may also be affected by changes in the issuer’s financial strength, the market’s perception of such strength, or in the credit rating of the issuer of the security. Liquidity risk is the risk that fixed-income securities may be difficult or impossible to sell at the time portfolio management would like or at the price portfolio management believes the security is currently worth. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk. To the extent a Fund invests in fixed-income securities in a particular industry or economic sector, its share values may fluctuate in response to events affecting that industry or sector. Securities underlying mortgage- and asset-backed securities, which may include subprime mortgages, also may be subject to a higher degree of credit risk, valuation risk, and liquidity risk. To the extent that a Fund invests in derivatives tied to fixed-income securities, the Fund may be more substantially exposed to these risks than a fund that does not invest in such derivatives. The market for certain fixed-income securities may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Similarly, the amount of assets deemed illiquid remaining within a Fund may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the Fund.
Foreign Exposure Risk.Within the parameters of its specific investment policies, each Fund may invest in foreign debt and equity securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. Additional risks may be present with respect to investments in securities of issuers or companies that are economically tied to different countries throughout the world. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks
69 | Janus Investment Fund

than investing in domestic securities because a Fund’s performance may depend on factors other than the performance of a particular company. These factors include:
Currency Risk.As long as a Fund holds a foreign security, its value will be affected by the value of the local currency relative to the U.S. dollar. When a Fund sells a foreign currency denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Foreign Market Risk.Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for a Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on a Fund. Such factors may hinder a Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.
Geographic Concentration Risk.To the extent that a Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on a Fund’s performance.
Political and Economic Risk.Foreign investments may be subject to increased political and economic risks, including the imposition of economic and other sanctions. Sanctions imposed by the U.S. Government on other countries or persons or issuers operating in such countries could restrict a Fund’s ability to buy affected securities or force a Fund to dispose of any affected securities it has previously purchased at an inopportune time. As a result, a Fund may experience a greater risk of loss with respect to securities impacted by such sanctions.
Political and economic risks may be heightened in emerging markets, which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of a Fund’s assets from that country. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.
Regulatory Risk.There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers.
Transaction Costs.Costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.
High-Yield Bond Risk.High-yield bonds (also known as “junk” bonds) are bonds rated below investment grade by the primary rating agencies such as Standard & Poor’s, Fitch, and Moody’s or are unrated bonds of similar quality. The value of lower quality bonds generally is more dependent on credit risk than investment grade bonds. Issuers of high-yield bonds may not be as strong financially as those issuing bonds with higher credit ratings and are more vulnerable to real or perceived economic changes, political changes, or adverse developments specific to the issuer. In addition, the junk bond market can experience sudden and sharp price swings.
70 | Janus Investment Fund

The secondary market on which high-yield securities are traded is less liquid than the market for investment grade securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. Additionally, it may be more difficult to value the securities because valuation may require more research, and elements of judgment may play a larger role in the valuation because there is less reliable, objective data available.
Because Janus Henderson Developed World Bond Fund, Janus Henderson High-Yield Fund, and Janus Henderson Multi-Sector Income Fund may invest a substantial amount of their net assets in high-yield bonds, investors should be willing to tolerate a corresponding increase in the risk of significant and sudden changes in net asset value.
Please refer to the “Explanation of Rating Categories” section of the SAI for a description of bond rating categories.
Impairment of Collateral Risk.The value of collateral, if any, securing a floating rate loan can decline, and may be insufficient to meet the borrower’s obligations or difficult to liquidate. In addition, Janus Henderson Developed World Bond Fund’s access to collateral may be limited by bankruptcy or other insolvency laws. Further, certain floating rate loans may not be fully collateralized and may decline in value.
Industry and Sector Risk.Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. Each Fund’s investments, if any, in multiple companies in a particular industry or economic sector may increase that Fund’s exposure to industry and sector risk.
Inflation Risk.Inflation risk is the risk that the value of certain assets or real income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the present value of a Fund’s assets and distributions may decline. This risk may be elevated in a low interest rate environment.
Inflation-Linked Investments Risk.Inflation-linked bonds (including TIPS), and other inflation-linked securities normally will decline in price when real interest rates rise. In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, inflation-linked bonds may experience greater losses than other fixed-income securities with similar durations. Except for a Fund’s investments in TIPS, which are guaranteed as to principal by the U.S. Treasury, the inflation-adjusted principal value or maturity amount of inflation-linked bonds repaid at maturity may be less than the original principal. Because of their inflation-linked adjustment feature, inflation-linked bonds typically have lower yields than conventional fixed-rate securities. In the event of deflation, where prices decline over time, the principal and income of inflation-linked bonds will likely decline, resulting in losses to a Fund.
Interest Rate Risk.Generally, a fixed-income security will increase in value when prevailing interest rates fall and decrease in value when prevailing interest rates rise. Longer-term securities are generally more sensitive to interest rate changes than shorter-term securities, but they generally offer higher yields to compensate investors for the associated risks. High-yield bond prices and floating rate debt security prices are generally less directly responsive to interest rate changes than investment grade issues or comparable fixed rate securities, and may not always follow this pattern.
Large Shareholder Risk.Certain large shareholders, such as Janus Henderson “fund of funds”, individuals, accounts, and affiliates of the Adviser, may hold substantial percentages of a Fund’s shares. A Fund is subject to the risk that a redemption by those shareholders of all or a large portion of their Fund shares may adversely affect the Fund’s performance by forcing the Fund to sell portfolio securities, potentially at disadvantageous prices, or to raise the cash needed to satisfy the redemption request. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a Fund having to sell securities or invest cash when it otherwise would not do so. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares.
Leverage Risk.Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose a Fund to greater risk and increase its costs. The use of leverage may cause a Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet the applicable requirements of the Investment Company Act of 1940, as amended, and the rules thereunder. Increases and decreases in the value of a Fund’s portfolio will be magnified when the Fund uses leverage.
71 | Janus Investment Fund

Liquidity Risk.A Fund may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are less liquid than other investments. Also, a Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, a Fund may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect a Fund’s value or prevent such Fund from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that a Fund invests in restricted securities that are deemed to be illiquid investments.
Liquidity risk may also refer to the risk that a Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of portfolio securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s net asset value, may increase brokerage costs, and may result in taxable capital gains.
Loan Risk.The Funds may invest in various commercial loans. The risks of such investments vary, depending on the type of loans underlying the investments, as described below.
Bank Loan Risk.The bank loans in which the Funds invest may be denominated in U.S. or non-U.S. currencies, including the euro. Bank loans are obligations of companies or other entities entered into in connection with recapitalizations, acquisitions, and refinancings. A Fund’s investments in bank loans are generally acquired as a participation interest in, or assignment of, loans originated by a lender or other financial institution. These investments may include institutionally-traded floating and fixed-rate debt securities. The bank loans underlying these securities often involve borrowers with low credit ratings whose financial conditions are troubled or uncertain, including companies that are highly leveraged or in bankruptcy proceedings. Participation interests and assignments involve credit, interest rate, and liquidity risk. Some participation interests and assignments may not be considered “securities,” and purchasers, such as a Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Additionally, because the Adviser, in the course of investing a Fund’s assets in loans, may have access to material non-public information regarding the borrower, the ability of the Fund to purchase or sell publicly-traded securities of such borrowers may be restricted. In addition, to the extent a Fund invests in non-U.S. bank loan investments, those investments also are subject to the risks of foreign investment, including those described under “European Investments Risk.”
If a Fund purchases a participation interest, it may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender. There are also risks involved in purchasing assignments. If a loan is foreclosed, a Fund may become part owner of any collateral securing the loan and may bear the costs and liabilities associated with owning and disposing of any collateral. The Fund could be held liable as a co-lender. In addition, there is no assurance that the liquidation of any collateral from a secured loan would satisfy a borrower’s obligations or that any collateral could be liquidated. There may be a number of intermediate participants in bank loan transactions and loan agreements that have specific rights, obligations, terms, and conditions. As such, any number of factors in an investment in bank loans could cause a Fund to lose income or principal on a particular investment, which in turn could affect the Fund’s returns, and you could lose money.
Interest rates on floating rate bank loans adjust with interest rate changes and/or issuer credit quality, and unexpected changes in such rates could result in losses to a Fund. Additionally, borrowers may pay back principal in whole or part, prior to scheduled due dates. Such prepayment may result in a Fund realizing less income on a particular investment and replacing the floating rate bank loan with a less attractive security, which may provide less return to the Fund.
Bank loans are generally less liquid than many other fixed-income securities and may be subject to restrictions on resale. Transactions in bank loans may take more than seven days to settle. As a result, the proceeds related to the sale of bank loans may not be available to make additional investments or to meet a Fund’s redemption obligations until a substantial period after the sale of the loans. To the extent that extended settlement creates short-term liquidity needs, a Fund may
72 | Janus Investment Fund

satisfy these needs by holding additional cash or selling other investments (potentially at an inopportune time, which could result in losses to the Fund).
A Fund may not be able to identify and invest in attractive floating rate bank loans, such as senior loans, as the market for such investments may be limited in certain economic conditions or because of a high number of potential purchasers of assignments and participations. A Fund may also invest in other floating rate debt securities or other investments. For example, the Fund may invest in junior or subordinated loans or unsecured loans. Such loans may not provide desired returns or may increase the potential for loss of income or principal. Bank loan investments may be generally considered speculative and risks arising from a Fund’s investments in bank loans may be similar to those of investments in “junk” bonds or below investment grade investments. A Fund’s investments in bank loans may be more sensitive to economic changes, political changes, or adverse developments specific to the borrower than higher quality investments.
Bridge Loan Risk.Investments in bridge loans subject a Fund to certain risks in addition to those described above. In addition, any delay in obtaining permanent financing subjects the bridge loan investor to increased risk. A borrower’s use of bridge loans also involves the risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness.
DIP Loan Risk.Investments in DIP loans are subject to the risk that the entity will not emerge from bankruptcy and will be forced to liquidate its assets. In the event of liquidation, a Fund’s only recourse will be against the property securing the DIP loan.
Mezzanine Loan Risk.Mezzanine loans generally are rated below investment grade, and frequently are unrated. Because mezzanine loans typically are the most subordinated debt obligation in an issuer’s capital structure, they are subject to the additional risk that the cash flow of the related borrower and any property securing the loan may be insufficient to repay the loan after the related borrower pays off any senior obligations. Mezzanine loans, which are usually issued in private placement transactions, may be considered illiquid. In addition, they are often used by smaller companies that may be highly leveraged, and in turn may be subject to a higher risk of default. Investment in mezzanine loans is a specialized practice that depends more heavily on independent credit analysis than investments in other fixed-income securities.
Market Risk.The value of a Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of a Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s net asset value will also decrease, which means if you sell your shares in the Fund you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.
The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Money Market Fund Investment Risk.A Fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, a Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and a Fund may lose money. To the extent a Fund transacts in instruments such as derivatives, such Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from such Fund’s investments in derivatives. An investment in a money market fund is not a
73 | Janus Investment Fund

bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share net asset value at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable net asset value could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their net asset values. Certain money market funds have in the past failed to maintain stable net asset values, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.
Rules adopted by the Securities and Exchange Commission (the “SEC”) require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s net asset value per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the Investment Company Act of 1940, as amended, are not subject to the floating net asset value requirements. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund.
Recently adopted amendments to Rule 2a-7 also require certain money market funds, excluding Government Money Market Funds and Retail Money Market Funds, to impose mandatory liquidity fees when a fund experiences net redemptions that exceed 5% of its net assets, unless the fund’s liquidity costs are de minimis (i.e., less than 1 basis point).
There can be no assurance that a Fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.
In addition to the fees and expenses that a Fund directly bears, a Fund indirectly bears the fees and expenses of any money market fund in which it invests.
Mortgage- and Asset-Backed Securities Risk.Rising interest rates tend to extend the duration of, or reduce the rate of prepayments on, both commercial mortgage-backed securities (“CMBS”) and residential mortgage-backed securities (“RMBS”), making them more sensitive to changes in interest rates (“extension risk”). As a result, in a period of rising interest rates, the price of mortgage-backed securities may fall, causing a Fund that holds mortgage-backed securities to exhibit additional volatility. Mortgage-backed securities are also subject to prepayment risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce a Fund’s returns because the Fund will have to reinvest that money at lower prevailing interest rates. Investments in certain mortgage-backed securities, including those comprised of subprime mortgages, may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities. Additionally, although mortgage-backed securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that guarantors or insurers will meet their obligations.
CMBS are subject to certain other risks. The market for CMBS developed more recently than that for RMBS and is relatively small in terms of outstanding principal amount of issues compared to the RMBS market. CMBS are also subject to risks associated with a lack of standardized terms, shorter maturities than residential mortgage loans, and payment of all or substantially all of the principal at maturity, rather than regular amortization of principal. Moreover, the type and use of a particular commercial property may add to the risk of CMBS investments. Adverse changes in economic conditions and circumstances are more likely to have an adverse impact on mortgage-backed securities secured by loans on commercial properties than on those secured by residential properties.
Similarly, the value of a Fund’s investments in asset-backed securities may be adversely affected by changes in interest rates, factors concerning the interests in and structure of the issuer or originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds, or other credit or liquidity enhancements, and/or the market’s assessment of the quality of the underlying assets. Generally, the originating bank or credit provider is neither the obligor nor the guarantor of the security, and interest and principal payments ultimately depend upon payment of the underlying loans by individuals. A Fund could incur a loss if the underlying loans are not paid. In addition, most asset-backed securities are subject to prepayment risk in a declining interest rate environment. The impact of prepayments on the
74 | Janus Investment Fund

value of asset-backed securities may be difficult to predict and may result in greater volatility. Rising interest rates tend to extend the duration of asset-backed securities, making them more volatile and sensitive to changing interest rates.
Newly Issued Securities Risk.The credit obligations in which certain Funds invest may include newly issued securities, or “new issues,” such as initial debt offerings. New issues may not be consistently available to a Fund for investing, particularly as a Fund’s asset base grows. Certain new issues, such as initial debt offerings, may be volatile in price due to the absence of a prior trading market, limited quantities available for trading and limited information about the issuer. A Fund may hold new issues for a short period of time. This may increase a Fund’s portfolio turnover and may lead to increased expenses for the Fund, such as commissions and transaction costs. New issues may have a magnified impact on the performance of a Fund during periods in which it has a small asset base. The impact of new issues on a Fund’s performance likely will decrease as the Fund’s asset size increases, which could reduce the Fund’s returns. In addition, new issues can experience an immediate drop in value after issuance if the demand for the securities does not continue to support the offering price.
Portfolio Management Risk.The Funds are actively managed investment portfolios and are therefore subject to the risk that the investment strategies and research process employed for the Funds may fail to produce the intended results. Accordingly, the Funds may underperform benchmark indices or other funds with similar investment objectives.
Private Placements and Other Exempt Securities Risk.Investments in private placements and other securities exempt from certain registration requirements could decrease a Fund’s liquidity profile or prevent a Fund from disposing of them promptly at advantageous prices. Private placements and other securities exempt from certain registration requirements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available. Transaction costs may be higher for these securities, and a Fund may get only limited information about the issuer of a private placement or other security exempt from certain registration requirements.
REIT and Real Estate-Related Securities Risk.To the extent a Fund holds REITs and REIT-like entities, it may be subject to the additional risks associated with REIT and REIT-like investments. REITs and REIT-like entities are subject to heavy cash flow dependency to allow them to make distributions to their shareholders. The prices of equity REITs are affected by changes in the value of the underlying property owned by the REITs, changes in capital markets and interest rates, management skill in running a REIT, and the creditworthiness of the REIT. The prices of mortgage REITs are affected by the quality of any credit they extend, the creditworthiness of the mortgages they hold, as well as by the value of the property that secures the mortgages. In addition, mortgage REITs (similar to direct investments in mortgage-backed securities) are subject to prepayment risk. Equity REITs and mortgage REITs are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation. There is also the risk that borrowers under mortgages held by a REIT or lessees of a property that a REIT owns may be unable to meet their obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may incur substantial costs associated with protecting its investments. While equity REITs and mortgage REITs may provide exposure to a large number of properties, such properties may be concentrated in a particular industry, region, or housing type, making such investments more vulnerable to unfavorable developments to economic or market events. Certain “special purpose” REITs in which a Fund may invest focus their assets in specific real property sectors, such as hotels, shopping malls, nursing homes, or warehouses, and are therefore subject to the specific risks associated with adverse developments in these sectors. A Fund’s shareholders will indirectly bear their proportionate share of the REIT’s expenses, in addition to their proportionate share of the Fund’s expenses. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.
Additionally, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. REITs are also subject to certain provisions under federal tax law and the failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing the return to the Fund on its investment in such company.
Sovereign Debt Risk.A Fund may invest in U.S. and non-U.S. government debt securities (“sovereign debt”). Investments in sovereign debt, especially the debt of certain emerging market countries, can involve a high degree of risk, including the risk that the governmental entity that controls the repayment of sovereign debt may not be willing or able to repay the principal and/or to pay the interest on its sovereign debt in a timely manner. A sovereign debtor’s willingness or ability to satisfy its debt obligation may be affected by various factors, including its cash flow situation, the extent of its foreign currency reserves,
75 | Janus Investment Fund

the availability of foreign exchange when a payment is due, the relative size of its debt position in relation to its economy as a whole, the sovereign debtor’s policy toward international lenders, and local political constraints to which the governmental entity may be subject. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies, and other entities. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to timely service its debts. A Fund may be requested to participate in the rescheduling of such sovereign debt and to extend further loans to governmental entities, which may adversely affect the Fund’s holdings. In the event of default, there may be limited or no legal remedies for collecting sovereign debt and there may be no bankruptcy proceedings through which the Fund may collect all or part of the sovereign debt that a governmental entity has not repaid. In addition, to the extent a Fund invests in non-U.S. sovereign debt, it may be subject to currency risk.
TBA Commitments Risk.A Fund may enter into “to be announced” or “TBA” commitments. Although TBA commitments must meet industry-accepted “good delivery” standards, there can be no assurance that a security purchased on a forward commitment basis will ultimately be issued or delivered by the counterparty. If the counterparty to a transaction fails to deliver the securities, a Fund could suffer a loss. Because TBA commitments do not require the delivery of a specific security, the characteristics of a security delivered to a Fund may be less favorable than expected. There is a risk that the security that a Fund buys will lose value between the purchase and settlement dates. When a Fund sells a TBA security prior to settlement, it does not participate in future gains or losses with respect to the security. A Fund is generally not required to pay for the TBA security until the settlement date and, as a result, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
Warrants and Rights Risk.The price, performance and liquidity of warrants and rights to purchase equity securities are typically linked to the underlying stock. These instruments have many characteristics of convertible securities and, similarly, will react to variations in the general market for equity securities. Rights are similar to warrants, but normally have a short duration and are distributed directly by the issuer to its shareholders. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.
Zero-Coupon, Step-Coupon and Pay-in-Kind Securities Risk.These securities are debt obligations that do not make regular cash interest payments. Zero-coupon and step-coupon securities are sold at a discount from their face value. Zero-coupon securities do not pay interest until maturity. Step-coupon securities pay coupon interest that increases or decreases over the life of the bond. Pay-in-kind securities pay interest through the issuance of additional securities. Because these securities do not pay current cash income, they are especially sensitive to changes in interest rates, and their prices are generally more volatile than debt securities that pay interest periodically. If an issuer of zero-coupon, step coupon or pay-in-kind securities defaults, a Fund may lose its entire investment. A Fund generally will be required to distribute dividends to shareholders representing the income from these instruments as it accrues, even though such Fund will not receive all of the income on a current basis or in cash. Thus, a Fund may have to sell other investments, including when it may not be advisable to do so, and use the cash proceeds to make income distributions to its shareholders.

Management of the Funds
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to each Fund. The Adviser is responsible for the day-to-day management of the Funds’ investment portfolios and furnishes continuous advice and recommendations concerning the Funds’ investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of each Fund. The Adviser utilizes personnel-sharing arrangements with its foreign (non-U.S.) affiliates, Janus Henderson Investors UK Limited ( “JHIUKL”) and Kapstream Capital Pty Limited (Australia) (“Kapstream”), pursuant to which certain Janus Henderson employees, acting for JHIUKL and Kapstream, may also serve as “associated persons” of the Adviser. In this capacity, such Janus Henderson employees, acting for Kapstream, for Janus Henderson Absolute Return Income Opportunities Fund, and JHIUKL, for Janus Henderson Developed World Bond Fund, are subject to the oversight and supervision of the Adviser and may provide portfolio management, research, and related services to the Funds on behalf of the Adviser.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of a Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate a Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that a Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to a Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for a Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Funds, including providing office space for the Funds and providing personnel to serve as officers to the Funds. The Funds reimburse the Adviser for certain of its costs in providing these services (to the extent the Adviser seeks reimbursement and such costs are not otherwise waived). These costs include some or all of the salaries, fees, and expenses of the Adviser’s employees and Fund officers, including the Funds’ Chief Compliance Officer and compliance staff, that provide specified administration and compliance services to the Funds. The Funds pay these costs based on out-of-pocket expenses incurred by the Adviser, and these costs are separate and apart from advisory fees and other expenses paid in connection with the investment advisory services the Adviser provides to the Funds.
Management expenses
Each Fund pays the Adviser an investment advisory fee and incurs expenses, including the distribution and shareholder servicing fees (12b-1 fee), administrative services fees payable pursuant to the Transfer Agency Agreement, custodian fees and expenses, legal and auditing fees, printing and mailing costs of sending reports and other information to existing shareholders, and Independent Trustees’ fees and expenses. Each Fund’s investment advisory fee is calculated daily and paid monthly. Each Fund’s advisory agreement details the investment advisory fee and other expenses that each Fund must pay.
The following table reflects each Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual compensation rate paid by each Fund to the Adviser after any applicable fee waivers and/or expense reimbursements. The rate shown is a fixed rate based on each Fund’s average daily net assets.

Expense Limitations
With respect to Janus Henderson Absolute Return Income Opportunities Fund, Janus Henderson Flexible Bond Fund, Janus Henderson High-Yield Fund, Janus Henderson Multi-Sector Income Fund, and Janus Henderson Short Duration Flexible Bond Fund, the Adviser has contractually agreed to waive the advisory fee payable by each Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees, out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees payable by any share class, acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below.

With respect to Janus Henderson Developed World Bond Fund, the Adviser has contractually agreed to waive the advisory fee payable by the Fund or reimburse expenses in an amount equal to the amount, if any, that the Fund’s total annual fund operating expenses, including the investment advisory fee, but excluding the fees payable pursuant to a Rule 12b-1 plan, shareholder servicing fees (but excluding out-of-pocket transfer agency/shareholder servicing costs, including networking/omnibus/shareholder servicing fees, payable by any share class), acquired fund fees and expenses, interest, dividends, taxes, brokerage commissions, and extraordinary expenses, exceed the annual rate shown below.
With respect to Janus Henderson Absolute Return Income Opportunities Fund, Janus Henderson Flexible Bond Fund, and Janus Henderson Multi-Sector Income Fund, the Adviser has also contractually agreed to waive and/or reimburse a portion of each Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated ETFs in which the Fund invests. Pursuant to this agreement, the waiver amount is equal to the amount of Fund assets invested in the affiliated ETFs, multiplied by an amount equal to the current daily unitary management fee of the affiliated

ETF, less certain asset-based operating fees and expenses incurred on a per-fund basis and paid by the Adviser with respect to the affiliated ETFs (including, but not limited to custody, sub-administration, transfer agency, legal, and audit fees).

Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund(s) that they manage, is included in the SAI.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that a Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to that Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of a Fund’s shares. A further discussion of potential
81 | Janus Investment Fund

conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Funds’ SAI.
82 | Janus Investment Fund

Other information
CLOSED FUND POLICIES
A Fund may limit sales of its Shares to new investors. If sales of a Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a Fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Funds
The Funds are distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Funds, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires each Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within a single Fund.
Distribution Schedule
Dividends from net investment income for Janus Henderson Developed World Bond Fund are normally declared and distributed monthly. Income dividends for each of the other Funds are normally declared daily (Saturdays, Sundays, and holidays included) and distributed as of the last business day of each month. If a month begins on a Saturday, Sunday, or holiday, dividends for those days are declared and distributed at the end of the preceding month. Income dividends begin accruing the day after a purchase is processed by the Funds or their agents. If shares are redeemed, you will receive all dividends accrued through the day the redemption is processed by the Funds or their agents. Distributions of net capital gains are normally declared and distributed in December. If necessary, dividends and net capital gains may be distributed at other times as well. The date you receive your distribution may vary depending on how your intermediary processes trades. Please consult your intermediary for details.
How Distributions Affect a Fund’s NAV
Distributions, other than daily income dividends, are paid to shareholders as of the record date of a distribution of a Fund, regardless of how long the Shares have been held. Undistributed income and net capital gains are included in each Fund’s daily net asset value (“NAV”). The share price of a Fund drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, a Fund declared a dividend in the amount of $0.25 per share. If the Fund’s share price was $10.00 on December 30, the Fund’s share price on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable mutual fund do not increase the value of your investment and may create income tax obligations.
“Buying a Dividend”
If you purchase shares of a Fund just before a distribution, you will pay the full price for the shares and receive a portion of the purchase price back as a taxable distribution. This is referred to as “buying a dividend.” In the above example, if you bought shares on December 30, you would have paid $10.00 per share. On December 31, the Fund would pay you $0.25 per share as a dividend and your shares would now be worth $9.75 per share. Unless your account is set up as a tax-advantaged account, dividends paid to you would be included in your gross income for federal income tax purposes, even though you may not have participated in the increase in NAV of the Fund, whether or not you reinvested the dividends. You should consult with your financial intermediary or tax adviser as to potential tax consequences of any distributions that may be paid shortly after purchase.
For your convenience, distributions of net investment income and net capital gains are automatically reinvested in additional Shares of the Fund without any sales charge. To receive distributions in cash, contact your financial intermediary, or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with a Fund. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Funds. The following is a general discussion of certain federal income tax consequences of investing in the Funds. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Funds. You should consult your tax adviser regarding the effect that an investment in a Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Funds are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of a Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income.
84 | Janus Investment Fund

Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of a Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by a Fund and capital gains from any sale or exchange of Fund shares. A Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although a Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”). A portion of a Fund’s distributions received from REITs may be classified as a return of capital for federal income tax purposes. As a result, a Fund that invests in REITs is more likely to make distributions that are treated as returns of capital, and possibly in greater amounts, than a fund that does not invest in REITs.
Distributions made by a Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of a Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Funds may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), a Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary (or the Fund, if you hold Class N Shares directly with a Fund) will report cost basis information to you and to the IRS. Your intermediary (or the Fund) will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method, unless you hold Class N Shares directly with a Fund in which case the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.

Taxation of the Funds
Dividends, interest, and some capital gains received by the Funds on foreign securities may be subject to foreign tax withholding or other foreign taxes. If a Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If a Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Funds.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Funds will monitor their transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Funds do not expect to pay any federal income or excise taxes because they intend to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all their net investment income and net capital gains. It is important that the Funds meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If a Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s guide
With certain exceptions, the Funds are generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Funds require that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with a Fund.
The Funds offer multiple classes of shares in order to meet the needs of various types of investors.
Class A Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, bank trust platforms, and retirement platforms. Class A Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services on behalf of their clients. In addition, Class A Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. Class A Shares may be offered without an initial sales charge to certain classes of investors such as purchases through certain retirement platforms, certain self-directed brokerage platforms where the financial intermediary is the broker of record, or fee-based platforms. See “Qualifying for a Waiver or Reduction of Class A Shares Sales Charge” in this Shareholder’s Guide for additional details.
Class C Shares are offered through financial intermediary platforms including, but not limited to, traditional brokerage platforms, mutual fund wrap fee programs, and bank trust platforms. Class C Shares pay up to 0.75% of net assets for payment to financial intermediaries for the provision of distribution services and up to 0.25% of net assets for the provision of shareholder services on behalf of their clients. In addition, Class C Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class C Shares are closed to investments by new employer-sponsored retirement plans and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares. Other share classes described in this Prospectus as eligible for investment by retirement plans are unaffected by this closure.
Class C Shares currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares. For more information, please refer to “Conversion of Class C Shares to Class A Shares.”
Class S Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms and asset allocation, mutual fund wrap, or other discretionary or nondiscretionary fee-based investment advisory programs. In addition, Class S Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class S Shares pay up to 0.25% of net assets to financial intermediaries for the provision of distribution services and/or shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
Class I Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. Class I Shares may also be available to retail investors purchasing in qualified or nonqualified accounts where such accounts are held through an omnibus account at your broker or financial intermediary. For more information please refer to Appendix A which accompanies this Prospectus. Class I Shares pay financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders. In addition to these fees and expenses paid by Class I Shares, your broker or financial intermediary may impose a commission or other sales charge on purchases. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative.
Class N Shares are generally available only to financial intermediaries purchasing on behalf of: 1) certain adviser-assisted, employer-sponsored retirement plans, including 401(k) plans, 457 plans, 403(b) plans, Taft-Hartley multi-employer plans, profit-sharing and money purchase pension plans, defined benefit plans, and certain welfare benefit plans, such as health savings accounts, and nonqualified deferred compensation plans; and 2) institutional investors and retail investors purchasing in qualified or nonqualified accounts, whose accounts are held through an omnibus account at their financial intermediary,
87 | Janus Investment Fund

and where the financial intermediary requires no payment or reimbursement from the Funds, the Adviser or its affiliates, for distribution-related or other shareholder services. Your broker or financial intermediary may impose a commission or other sales charge on purchases of Class N Shares. The nature and amount of such commission or other sales charge for your purchases is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative. Class N Shares also are available to Janus Henderson proprietary products. Class N Shares also are available to certain direct institutional investors approved by the Distributor including, but not limited to, corporations, certain retirement plans, public plans, and foundations and endowments, subject to minimum investment requirements.
Class R Shares are offered through financial intermediary platforms including, but not limited to, retirement platforms. Class R Shares pay up to 0.50% of net assets to financial intermediaries for the provision of distribution services and, to a certain extent, shareholder services and up to 0.25% of net assets for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of the plan or plan participants.
Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, Class T Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms. Class T Shares pay up to 0.25% of net assets to financial intermediaries for the provision of administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided to or on behalf of shareholders.
The Shares are not offered directly to individual investors. Consult with your financial intermediary representative for additional information on whether the Shares are an appropriate investment choice. Certain funds may not be available through certain of these intermediaries and not all financial intermediaries offer all classes of shares. If your financial intermediary offers more than one class of shares, you should carefully consider which class of shares to purchase. Certain classes have higher expenses than other classes, which may lower the return on your investment. For instructions on how to purchase, exchange, or redeem Shares, contact your financial intermediary or refer to your plan documents. For Class N Shares held directly with a Fund, please contact a Janus Henderson representative at 1-800-333-1181.
Pricing of fund shares
The per share NAV for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. A Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which a Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. Foreign securities held by a Fund may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of a Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem a Fund’s Shares.
The price you pay for purchases of Shares is the public offering price, which is the NAV next calculated after your request is received in good order by a Fund or its agents, plus, for Class A Shares, any applicable initial sales charge. The price you pay to sell Shares is also the NAV, although for Class A Shares and Class C Shares, a contingent deferred sales charge may be taken out of the proceeds. For Class I Shares or Class N Shares, although purchases and redemptions are made at the net asset value calculated after your order is received by the Funds, you may be charged a commission by your broker or other financial institution. The nature and amount of the commission and the times at which it may be collected are determined by your broker. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares. In order to receive a day’s price, your order must be received in good order by a Fund or its agents by the close of the trading session of the NYSE. Each Fund’s per share class NAV is available at janushenderson.com/pricing (or janushenderson.com/nav for shareholders of Class D Shares).
Fund holdings are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). To the extent available, domestic and foreign equity securities traded on a securities exchange,
88 | Janus Investment Fund

including ETFs, are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The Valuation Procedures provide for the use of systematic fair valuation models provided by an independent pricing service to value foreign equity securities in order to adjust for stale pricing, which may occur between the close of certain foreign exchanges and the close of the NYSE. The methodologies employed when fair valuing Fund holdings may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.
Due to the subjective nature of systematic fair valuation, the value of a particular security may be different from the last quoted market price. Systematic fair valuation may reduce arbitrage activity involving the frequent buying and selling of mutual fund shares by investors seeking to take advantage of a perceived lag between a change in the value of a Fund’s portfolio securities and the reflection of such change in a Fund’s NAV, as further described in the “Excessive Trading” section of this Prospectus. While funds that invest in foreign securities may be at a greater risk for arbitrage activity, such activity may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities or high-yield fixed-income securities, may be subject to attempted use of arbitrage techniques. To the extent that the valuation of a security is different from the security’s market value, short-term arbitrage traders buying and/or selling shares of a Fund may dilute the NAV of the Fund, which negatively impacts long-term shareholders. The Valuation Procedures and the Trust’s excessive trading policies and procedures may not completely eliminate short-term trading in certain omnibus accounts and other accounts traded through intermediaries.
The value of the securities of other mutual funds held by a Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation.
Generally, futures contracts and/or options on futures are valued at the actual settlement price on valuation date on the exchange as reported by an approved vendor. In the event actual settlement price is unavailable or is deemed unreliable, then the reported settlement price (there can be different settlement prices at different times), early settlement price or the last trade price shall be used. Option contracts are valued using an evaluated price from an approved vendor. Evaluated prices can be derived using an option pricing model, including inputs derived from volatility surfaces, market data and characteristics of the portfolio investment. In cases when an approved vendor cannot provide coverage for an option, a broker quotation or an internal valuation using the Black-Scholes model, or other appropriate option pricing model shall be used. Index swaps, credit default swaps, and interest rate swaps are typically valued using an evaluated price from an approved vendor. Evaluated prices will generally have a fixed and floating leg with the present value of each being calculated based on the terms of the trade.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Funds under the arrangements made between your financial intermediary or plan sponsor and its
89 | Janus Investment Fund

customers. The Funds are not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Choosing a share class
Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, Class R Shares, and Class T Shares are offered by this Prospectus. The Funds offer multiple classes of shares in order to meet the needs of various types of investors. For more information about these classes of Shares and whether or not you are eligible to purchase these Shares, please call 1-877-335-2687.
Each class represents an interest in the same portfolio of investments, but has different charges and expenses, allowing you to choose the class that best meets your needs. For an analysis of fees associated with an investment in each share class or other similar funds, please visit www.finra.org/fundanalyzer. When choosing a share class, you should consider:
how much you plan to invest;
how long you expect to own the shares;
the expenses paid by each class; and
for Class A Shares and Class C Shares, whether you qualify for any reduction or waiver of any sales charges.

Class A, Class C, Class S, and Class T shares held through certain supermarket and/or self-directed brokerage accounts, or through wrap programs, may not be subject to this minimum. Please contact your financial intermediary for more information. For Class R shareholders, there is no investment minimum for defined contribution plans. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information regarding account minimums.
(3) 
In addition to these fees and expenses, your broker or financial intermediary may impose a commission or other sales charge on your purchases of Class I Shares or Class N Shares. The nature and amount of such commission or other sales charge is determined solely by your broker or financial intermediary; for more information please contact your broker or financial intermediary representative.
(4) 
Exceptions to this minimum may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts.
(5) 
Investors in certain tax-advantaged accounts or accounts held through certain wrap programs or bank trust platforms may not be subject to this minimum.
Distribution, servicing, and administrative fees
Distribution and Shareholder Servicing Plans
Under separate distribution and shareholder servicing plans adopted in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended, for Class A Shares, Class S Shares, and Class R Shares (each a “Plan”) and Class C Shares (the “Class C Plan”), each Fund pays the Distributor a fee for the sale and distribution and/or shareholder servicing of the Shares based on the average daily net assets of each, at the following annual rates:
Class
12b-1 Fee for the Funds
Class A Shares
0.25%
Class C Shares
1.00%(1)
Class S Shares
0.25%
Class R Shares
0.50%
(1) 
Up to 0.75% of this fee is for distribution services and up to 0.25% of this fee is for shareholder services.
Under the terms of each Plan, the Trust is authorized to make payments to the Distributor for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Funds.
The Distributor is entitled to retain all fees paid under the Class C Plan for the first 12 months on any investment in Class C Shares to recoup its expenses with respect to the payment of commissions on sales of Class C Shares. Financial intermediaries will become eligible for compensation under the Class C Plan beginning in the 13th month following the purchase of Class C Shares, although the Distributor may, pursuant to a written agreement between the Distributor and a particular financial intermediary, pay such financial intermediary 12b-1 fees prior to the 13th month following the purchase of Class C Shares.
Financial intermediaries may from time to time be required to meet certain criteria in order to receive 12b-1 fees. The Distributor is entitled to retain some or all fees payable under each Plan in certain circumstances, including when there is no broker of record or when certain qualification standards have not been met by the broker of record.
Because 12b-1 fees are paid out of a Fund’s assets on an ongoing basis, over time they will increase the cost of your investment and may cost you more than paying other types of sales charges.
Administrative Fees
Class A Shares, Class C Shares, and Class I Shares
Certain, but not all, intermediaries may charge fees for administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided by intermediaries on behalf of shareholders of the Funds. Order processing includes the submission of transactions through the National Securities Clearing Corporation (“NSCC”) or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent pays these administrative fees to intermediaries on behalf of the Funds. The Transfer Agent is then reimbursed by the Funds for such payments. Because the form and amount charged varies by intermediary, the amount of the administrative fee borne by the class is an average of all fees charged by intermediaries. In the event an intermediary receiving payments from the Transfer Agent on behalf of the Funds converts from a networking structure to an omnibus account structure, or otherwise
92 | Janus Investment Fund

experiences increased costs, fees borne by the Shares may increase. The Funds’ Trustees have set limits on fees that the Funds may incur with respect to administrative fees paid for omnibus or networked accounts. Such limits are subject to change by the Trustees in the future.
Class S Shares, Class R Shares, and Class T Shares
The Transfer Agent receives an administrative services fee at an annual rate of 0.25% of the average daily net assets of Class S Shares, Class R Shares, and Class T Shares of each Fund for providing, or arranging for the provision by intermediaries of, administrative services, including recordkeeping, subaccounting, order processing for omnibus or networked accounts, or other shareholder services provided on behalf of shareholders of the Funds. Order processing includes the submission of transactions through the NSCC or similar systems, or those processed on a manual basis with the Adviser. Other shareholder services may include the provision of order confirmations, periodic account statements, forwarding prospectuses, shareholder reports, and other materials to existing customers, and answering inquiries regarding accounts. The Transfer Agent expects to use all or a significant portion of this fee to compensate intermediaries and retirement plan service providers for providing these services to their customers who invest in the Funds. The Transfer Agent or its affiliates may also pay fees for services provided by intermediaries to the extent the fees charged by intermediaries exceed the 0.25% of net assets charged to the Funds.
For all share classes, the Transfer Agent also seeks reimbursement for costs it incurs as transfer agent and for providing servicing.
Payments to financial intermediaries by the Adviser or its affiliates
From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries that sell certain classes of Shares of the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. Sales- and asset-based payments currently range up to 25 basis points on sales and up to 20 basis points on average annual net assets of shares held through the intermediary and are subject to change. Payments based on transactional charges may include the payment or reimbursement of all or a portion of “ticket charges.” Ticket charges are fees charged to salespersons purchasing through a financial intermediary firm in connection with mutual fund purchases, redemptions, or exchanges. The payment or reimbursement of ticket charges creates an incentive for salespersons of an intermediary to sell shares of Janus Henderson funds over shares of funds for which there is lesser or no payment or reimbursement of any applicable ticket charge. Payments made with respect to certain classes of Shares may create an incentive for an intermediary to promote or favor other share classes of the Janus Henderson funds. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries, including, but not limited to, the share class or share classes selected by the financial intermediary for a particular channel, platform or investor type, whether such class is open to new investors on a particular platform or channel, the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, redemption and retention rates of assets held through the intermediary, the willingness of the intermediary to cooperate with the Adviser’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors may change from time to time. Broker-dealer firms currently receiving or expected to receive these fees are listed in the SAI.
In addition, the Adviser, the Distributor, or their affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the NSCC or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services.
The Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates
93 | Janus Investment Fund

with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments, reimbursements, and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. However, as described elsewhere in this Prospectus, your financial adviser and/or his or her firm may also receive 12b-1 fees and/or administrative services fees in connection with your purchase and retention of Janus Henderson funds. When such fees are combined with the payments described above, the aggregate payments being made to a financial intermediary may be substantial. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Funds and, if applicable, when considering which share class of a Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
With the exception of Class N Shares, purchases of Shares may generally be made only through institutional channels such as financial intermediaries and retirement platforms. Class N Shares may be purchased directly with the Funds in certain circumstances as described in the eligibility discussion at the beginning of this “Shareholder’s Guide” section. Contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with the Adviser or refer to your plan documents for information on how to invest in each Fund, including additional information on minimum initial or subsequent investment requirements. Under certain circumstances, a Fund may permit an in-kind purchase of Shares. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Funds’ behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Funds or that provide services in connection with investments in the Funds. You should consider such arrangements when evaluating any recommendation of the Funds.
Each Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Funds are not intended for excessive trading. For more information about the Funds’ policy on excessive trading, refer to “Excessive Trading.”
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) is required to verify certain information on your account application as part of its Anti-Money
94 | Janus Investment Fund

Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) may temporarily limit additional share purchases. In addition, your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary (or a Janus Henderson representative, if you hold Class N Shares directly with a Fund) if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Minimum Investment Requirements
Class A Shares, Class C Shares, Class S Shares, and Class T Shares
The minimum investment is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. In addition, shares held through certain supermarket and/or self-directed brokerage accounts, or through wrap programs, may not be subject to these minimums. Investors should refer to their intermediary for additional information.
The maximum purchase in Class C Shares is $500,000 for any single purchase. The sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $500,000 of Fund shares. Effective on or about December 9, 2024, the maximum purchase in Class C Shares will change to $250,000 for any single purchase. At that time, the sales charge and expense structure of Class A Shares may be more advantageous for investors purchasing more than $250,000 of Fund shares.
Class I Shares
Accounts offered through an intermediary institution must meet the minimum investment requirements of $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Directors, officers, and employees of Janus Henderson Group plc (“JHG”) and its affiliates, as well as Trustees and officers of the Funds, may purchase Class I Shares through certain financial intermediaries’ institutional platforms. For more information about this program and eligibility requirements, please contact a Janus Henderson representative at 1-800-333-1181. Exceptions to these minimums may apply for certain tax-advantaged, tax-qualified and retirement plans, including health savings accounts, accounts held through certain wrap programs, and certain retail brokerage accounts. For additional information, contact your intermediary, plan sponsor, or administrator, as applicable.
Class N Shares
For retail investors whose accounts are held through an omnibus account at their financial intermediary, the minimum investment is $2,500 per Fund account. Investors in certain tax-advantaged accounts or accounts held through certain wrap programs or bank trust platforms may not be subject to this minimum. For institutional investors investing directly with a Fund, the minimum investment is $1 million per Fund account. There is no investment minimum for adviser-assisted, employer-sponsored retirement plans, including health savings accounts. For additional information, contact your intermediary, plan sponsor, administrator, or a Janus Henderson representative, as applicable.
Class R Shares
There is no investment minimum for investors in a defined contribution plan. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information regarding account minimums. For all other account types, the minimum investment is $2,500.
Class A Shares, Class C Shares, Class S Shares, Class I Shares, Class N Shares, and Class T Shares
Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject
95 | Janus Investment Fund

to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. If you hold Class N Shares directly with a Fund, you may receive written notice prior to the closure of your Fund account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Each Fund reserves the right to change the amount of these minimums or maximums from time to time or to waive them in whole or in part.
Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus Henderson representative for details.
Initial Sales Charge
Class A Shares
An initial sales charge may apply to your purchase of Class A Shares of the Funds based on the amount invested, as set forth in the table below. The sales charge is allocated between the Distributor and your financial intermediary. Sales charges, as expressed as a percentage of offering price and as a percentage of your net investment, are shown in the table. The dollar amount of your initial sales charge is calculated as the difference between the public offering price and the net asset value of those shares. Since the offering price is calculated to two decimal places using standard rounding criteria, the number of shares purchased and the dollar amount of your sales charge as a percentage of the offering price and of your net investment may be higher or lower than the amounts set forth in the table depending on whether there was a downward or upward rounding.

For purchases of Class A Shares of $1,000,000 or greater, from its own assets, the Distributor generally pays financial intermediaries commissions as follows:
1.00% on amounts of $1,000,000 but under $4,000,000;
0.50% on amounts of $4,000,000 but under $10,000,000;

0.25% on amounts of $10,000,000 and above.
The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.
Effective on or about December 9, 2024, the Class A Shares sales charge schedule will be revised as set forth in the table below.

Effective on or about December 9, 2024, for purchases of Class A Shares of $250,000 or greater, from its own assets, the Distributor generally pays financial intermediaries commissions as follows:
1.00% on amounts of $250,000 but under $4,000,000;
0.50% on amounts of $4,000,000 but under $10,000,000;
0.25% on amounts of $10,000,000 and above.
The purchase totals eligible for these commissions are aggregated on a rolling one year basis so that the rate payable resets to the highest rate annually.
Qualifying for a Waiver or Reduction of Class A Shares Sales Charge
Class A Shares of the Funds may be purchased without an initial sales charge by the following persons (and their family members): (i) registered representatives and other employees of intermediaries that have selling agreements with the Distributor to sell Class A Shares; (ii) directors, officers, and employees of JHG and its affiliates; and (iii) Trustees and officers of the Trust. A “family member” includes, but is not necessarily limited to (based on the reasonable discretion of the Adviser), a qualifying person’s sibling, spouse or domestic partner, lineal ascendant (mother, father, grandmother, grandfather, great-grandmother, great-grandfather), lineal descendant (son, daughter, step-son, step-daughter, grandson, granddaughter, great-grandson, great-granddaughter) or any sibling, spouse or domestic partner of a family member who is a lineal descendant or ascendant of a qualifying person. In addition, the initial sales charge may be waived on purchases of Class A Shares by the following persons: (i) investors purchasing Class A Shares through financial intermediaries on behalf of certain adviser-assisted, employer-sponsored retirement plans, including defined contribution plans, defined benefit plans and other welfare benefit plans such as health savings accounts and voluntary employees’ beneficiary association trust accounts; (ii) investors purchasing Class A Shares through a financial intermediary’s self-directed brokerage platform where the financial intermediary is the broker of record; and (iii) investors purchasing Class A Shares through fee-based broker-dealers or financial advisors, primarily on their advisory account platform(s) where such broker-dealer or financial advisor imposes additional fees for services connected to the advisory account. Adviser-assisted, employer-sponsored defined contribution plans include, for example, 401(k) plans, 457 plans, 403(b) plans, profit sharing and money purchase pension plans. For purposes of qualifying for a waiver of the initial sales charge, the following retirement accounts are not eligible: 403(b) custodial accounts
97 | Janus Investment Fund

where shares are held on behalf of the individual, and not on behalf of the plan or plan trust, SEP IRAs, Simple IRAs, SAR-SEPs, or Keogh plans. To facilitate the waiver of a sales charge, the Distributor requires an agreement with the financial intermediary submitting trades on behalf of eligible investors.
You may be able to lower your Class A Shares sales charge under certain circumstances. For example, you can combine Class A Shares and Class C Shares you already own (either in these Funds or certain other Janus Henderson funds) with your current purchase of Class A Shares of the Funds and certain other Janus Henderson funds (including Class C Shares of those funds) to take advantage of the breakpoints in the sales charge schedule as set forth above. Certain circumstances under which you may combine such ownership of Shares and purchases are described below. Contact your financial intermediary for more information.
In order to obtain a sales charge discount, you should inform your financial intermediary of other accounts in which there are Fund holdings eligible to be aggregated to meet a sales charge breakpoint. These other accounts may include the accounts described under “Aggregating Accounts.” You may need to provide documents such as account statements or confirmation statements to prove that the accounts are eligible for aggregation. The Letter of Intent described below requires historical cost information in certain circumstances. You should retain records necessary to show the price you paid to purchase Fund shares, as the Funds, their agents, or your financial intermediary may not retain this information.
Right of Accumulation.You may purchase Class A Shares of a Fund at a reduced sales charge by aggregating (i) the dollar amount of the new purchase (measured by the offering price) with (ii) your holdings in all Class A Shares of the Fund and certain other classes (Class A Shares and Class C Shares of the Trust) of Janus Henderson funds held by you, and held in the accounts identified under “Aggregating Accounts” (“collective holdings”). Subject to your financial intermediary’s or record keeper’s capabilities, collective holdings will be calculated as the higher of (i) the current value of such holdings (the market value) as of the day prior to your new purchase or (ii) the amount initially invested (including reinvested dividends and capital gains, but excluding capital appreciation) less any withdrawals (the cost value). The applicable sales charge will be applied to such aggregated amount. In order for your purchases and collective holdings to be aggregated for purposes of qualifying for a reduced sales charge, they must have been made through one financial intermediary and you must provide sufficient information to your financial intermediary at the time of purchase to permit verification that the purchase qualifies for the reduced sales charge. The qualification of a purchase for the reduced sales charge does not ensure the future availability of the right of accumulation, which is subject to modification or discontinuance at any time.
Letter of Intent.You may obtain a reduced sales charge on Class A Shares by signing a Letter of Intent indicating your intention to purchase $50,000 or more of Class A Shares (including Class A Shares in other series of the Trust) over a 13-month period. The term of the Letter of Intent will commence upon the date you sign the Letter of Intent. Investments made prior to the signing date are not aggregated with, and are not eligible to be included toward, the investment goal.
You must refer to such Letter when placing orders. With regard to a Letter of Intent, the amount of investment for purposes of applying the sales load schedule includes (i) the historical cost (what you actually paid for the shares at the time of purchase, including any sales charges) of all Class A Shares acquired during the term of the Letter of Intent, minus (ii) the value of any redemptions of Class A Shares made during the term of the Letter of Intent. Capital appreciation, capital gains, and reinvested dividends earned during the Letter of Intent period do not apply toward its completion. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. A portion of shares purchased may be held in escrow to pay for any sales charge that may be applicable. If the goal is not achieved within the period, you must pay the difference between the sales charges applicable to the purchases made and the charges previously paid, or an appropriate number of escrowed shares will be redeemed. Please contact your financial intermediary to obtain a Letter of Intent application.
Aggregating Accounts.To take advantage of lower Class A Shares sales charges on large purchases or through the exercise of a Letter of Intent or right of accumulation, investments made by you, your spouse, and your children under age 21 may be aggregated if made for your own account(s) and/or certain other accounts such as:
trust accounts established by the above individuals (or the accounts of the primary beneficiary of the trust if the person who established the trust is deceased);
solely controlled business accounts; and
single participant retirement plans.
98 | Janus Investment Fund

To receive a reduced sales charge under rights of accumulation or a Letter of Intent, you must notify your financial intermediary of any eligible accounts that you, your spouse, and your children under age 21 have at the time of your purchase.
You may access information regarding sales loads, breakpoint discounts, and purchases of the Funds’ shares, free of charge, and in a clear and prominent format, on our website at janushenderson.com/breakpoints, and by following the appropriate hyperlinks to the specific information.
Conversion of Class C Shares to Class A Shares
The Funds currently implement an automatic conversion feature pursuant to which Class C Shares that have been held for eight years are automatically converted to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month of the eighth anniversary of the date of purchase. Class C Shares purchased through the reinvestment of dividends and other distributions on Class C Shares will convert to Class A Shares at the same time as the Class C Shares with respect to which they were purchased.
For Class C Shares held in omnibus accounts on intermediary platforms, the Funds will rely on these intermediaries to implement this conversion feature. Your financial intermediary may have separate policies and procedures as to when and how Class C Shares may be converted to Class A Shares. Please contact your financial intermediary for additional information.
It is expected that the conversion of Class C Shares to Class A Shares of the same Fund will not result in a taxable event. Please consult your tax adviser for further information.
Commission on Class C Shares
The Distributor may compensate your financial intermediary at the time of sale at a commission rate of 1.00% of the net asset value of the Class C Shares purchased. Service providers to financial intermediaries will not receive this amount if they receive 12b-1 fees from the time of initial investment of assets in Class C Shares.
Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (“CDSC”) waivers. In all instances, it is the shareholder’s responsibility to notify a Fund, or the shareholder’s financial intermediary at the time of purchase, of any relationship or other facts qualifying the shareholder for sales charge waivers or discounts. Certain sales charge waivers and/or discounts are described in Appendix A – Intermediary Sales Charge Waivers and Discounts. These sales charge waivers and/or discounts are available only if you purchase your shares through the designated intermediaries. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase Fund shares through another intermediary to receive these waivers or discounts.
Exchanges
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with a Fund or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of a Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan, with the exception of the Janus Henderson money market funds. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund; all other account types can only exchange to Janus Henderson Government Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received. A Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
99 | Janus Investment Fund

You must meet the minimum investment amount for each fund.
The exchange privilege is not intended as a vehicle for short-term or excessive trading. A Fund may suspend or terminate the exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds will work with intermediaries to apply the Funds’ exchange limits. However, the Funds may not always have the ability to monitor or enforce the trading activity in such accounts.
Each Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Class C Shares are closed to investments by new employer-sponsored retirement plans, and existing employer-sponsored retirement plans are no longer able to make additional purchases or exchanges into Class C Shares.
Your Class C Shares that have been held for eight years will automatically convert to Class A Shares without the imposition of any sales charge, fee or other charge. The conversion will generally occur no later than ten business days in the month following the month in which the eighth anniversary of the date of purchase occurs. For more information refer to “Conversion of Class C Shares to Class A Shares.”
Waiver of Sales Charges
Class A Shares received through an exchange of Class A Shares of another fund of the Trust will not be subject to an initial sales charge. In addition, Class A Shares received through an exchange of Class C Shares due to an intermediary-driven conversion or an automatic conversion after eight years, or a conversion from a fee-based account to a brokerage account, will not be subject to an initial sales charge. Class A Shares or Class C Shares received through an exchange of Class A Shares or Class C Shares, respectively, of another fund of the Trust will not be subject to any applicable CDSC at the time of the exchange. CDSC applicable to redemptions of Class A Shares or Class C Shares will continue to be measured on the Shares received by exchange from the date of your original purchase. For more information about the CDSC, please refer to “Redemptions.” While Class C Shares do not have any front-end sales charges, their higher annual fund operating expenses mean that over time, you could end up paying more than the equivalent of the maximum allowable front-end sales charge.
Redemptions
With certain exceptions, the Funds are generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Funds.
Redemptions, like purchases, may generally be effected only through financial intermediaries, retirement platforms, and by certain direct institutional investors holding Class N Shares. Please contact your financial intermediary or a Janus Henderson representative (1-800-333-1181) if you hold Class N Shares directly with a Fund or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of each Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by a Fund or its agents. Redemption proceeds, less any applicable CDSC for Class A Shares or Class C Shares, will normally be sent within two business days following receipt of the redemption order. The Funds typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Each Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Funds to redeem their Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
Each Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. If you hold Class N Shares directly with a Fund, you may receive written notice prior to the closure of your
100 | Janus Investment Fund

Fund account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of a Fund’s Shares. Redemptions by these large shareholders of their holdings in a Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect a Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in a Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, each Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of that Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, a Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If a Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While a Fund may pay redemptions in-kind, a Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If a Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Systematic Withdrawal Plan
Class A Shares and Class C Shares
You may arrange for periodic redemptions of Class A Shares or Class C Shares by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Any resulting CDSC may be waived, however, the maximum annual rate at which shares subject to a CDSC may be redeemed, pursuant to a systematic withdrawal plan, without paying a CDSC, is 12% of the net asset value of the account. Certain other terms and minimums may apply. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Class S Shares, Class I Shares, Class N Shares, Class R Shares, and Class T Shares
You may arrange for periodic redemptions by authorizing your financial intermediary (or the Adviser, if you hold Class N Shares directly with a Fund) to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary or a Janus Henderson representative for details.
Contingent Deferred Sales Charge
Class A Shares and Class C Shares
A 1.00% CDSC may be deducted with respect to Class A Shares purchased without an initial sales charge if redeemed within 12 months of purchase, unless any of the CDSC waivers listed apply. A 1.00% CDSC will be deducted with respect to Class C Shares redeemed within 12 months of purchase, unless a CDSC waiver applies. The CDSC will be based on the lower of the original purchase price or the value of the redemption of the Class A Shares or Class C Shares redeemed, as applicable.
101 | Janus Investment Fund

CDSC Waivers
There are certain cases in which you may be exempt from a CDSC charged to Class A Shares and Class C Shares. Among others, these include:
Upon the death or disability of an account owner;
Retirement plans and certain other accounts held through a financial intermediary where no sales charge or commission was paid on the purchase of such shares;
Retirement plan shareholders taking required minimum distributions;
The redemption of Class A Shares or Class C Shares acquired through reinvestment of Fund dividends or distributions;
The portion of the redemption representing appreciation as a result of an increase in NAV above the total amount of payments for Class A Shares or Class C Shares during the period during which the CDSC applied; or
If a Fund chooses to liquidate or involuntarily redeem shares in your account.
To keep the CDSC as low as possible, Class A Shares or Class C Shares not subject to any CDSC will be redeemed first, followed by shares held longest.
Reinstatement Privilege
For each redemption of Class A Shares, you have a one-time right to reinvest the proceeds of such redemption into Class A Shares of the same or another fund within 90 days of the redemption date at the current NAV (without an initial sales charge). You will not be reimbursed for any CDSC paid on your redemption of Class A Shares.
Excessive trading
Excessive and Short-Term Trading Policies and Procedures
The Trustees have adopted policies and procedures with respect to short-term and excessive trading of Fund shares (“excessive trading”). The Funds are intended for long-term investment purposes, and the Funds will take reasonable steps to attempt to detect and deter short-term and excessive trading. Transactions placed in violation of the Funds’ exchange limits or excessive trading policies and procedures may be cancelled or rescinded by a Fund by the next business day following receipt by the Fund. The trading history of accounts determined to be under common ownership or control within any of the Janus Henderson funds may be considered in enforcing these policies and procedures. Investors should be aware that the Funds are also available for purchase through third party intermediaries.
The Janus Henderson funds attempt to deter excessive trading through at least the following methods:
exchange limitations as described under “Exchanges”;
fair valuation of securities as described under “Pricing of Fund Shares”; and
trade monitoring.
The Funds monitor for patterns of shareholder short-term trading and may suspend or permanently terminate the purchase and exchange privilege of any investor who is identified as having a pattern of short-term trading. The Funds at all times reserve the right to reject any purchase or exchange request and to modify or terminate the purchase and exchange privileges for any investor for any reason without prior notice, in particular, if the trading activity in the account(s) is deemed to be disruptive to a Fund.
The Funds’ Trustees may approve from time to time a redemption fee to be imposed by any Janus Henderson fund, subject to 60 days’ notice to shareholders of that fund.
Investors in other share classes who place transactions through the same financial intermediary on an omnibus basis may be deemed part of a group for the purpose of the Funds’ excessive trading policies and procedures and may be rejected in whole or in part by a Fund. Transactions accepted by a financial intermediary in violation of the Funds’ excessive trading policies may be cancelled or revoked by a Fund by the next business day following receipt by that Fund.
In an attempt to deter excessive trading in omnibus accounts, the Funds or their agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. Such restrictions may include, but are not limited to, requiring that trades be placed by U.S. mail, prohibiting future purchases by investors who have recently

redeemed Fund shares, requiring intermediaries to report information about customers who purchase and redeem large amounts, and similar restrictions. The Funds’ ability to impose such restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems’ capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries.
Generally, the Funds’ excessive trading policies and procedures do not apply to (i) a money market fund, although money market funds at all times reserve the right to reject any purchase request (including exchange purchases) for any reason without prior notice; (ii) transactions in the Janus Henderson funds by a Janus Henderson “fund of funds”; (iii) transactions in the Funds by a collective investment trust managed by the Adviser; (iv) transactions in the Funds by a charitable foundation; (v) periodic rebalancing and identifiable transactions by certain funds of funds and asset allocation programs to realign portfolio investments with target allocations; and (vi) systematic purchase, exchange, or redemption programs.
The Funds’ policies and procedures regarding excessive trading may be modified at any time by the Funds’ Trustees.
Excessive Trading Risks
Excessive trading may present risks to a Fund’s long-term shareholders. Excessive trading into and out of a Fund may disrupt portfolio investment strategies, may create taxable gains to remaining Fund shareholders, and may increase Fund expenses, all of which may negatively impact investment returns for all remaining shareholders, including long-term shareholders.
Funds that invest in foreign securities may be at a greater risk for excessive trading. Investors may attempt to take advantage of anticipated price movements in securities held by a fund based on events occurring after the close of a foreign market that may not be reflected in the fund’s NAV (referred to as “price arbitrage”). Such arbitrage opportunities may also arise in funds which do not invest in foreign securities, for example, when trading in a security held by a fund is halted and does not resume prior to the time the fund calculates its NAV (referred to as “stale pricing”). Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be subject to attempted use of arbitrage techniques. To the extent that a Fund’s valuation of a security differs from the security’s market value, short-term arbitrage traders may dilute the NAV of a Fund, which negatively impacts long-term shareholders. There is potential for short-term arbitrage trades to dilute the value of the shares held by a Fund despite the Funds’ adoption of policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing, and other potential pricing inefficiencies.
There is no assurance that the policies and procedures adopted by the Funds to detect and deter excessive trading will be effective in all circumstances. For example, for share classes sold through financial intermediaries, the Funds may be unable to completely eliminate the possibility of excessive trading in certain omnibus accounts and other accounts traded through intermediaries. Omnibus accounts may effectively conceal the identity of individual investors and their transactions from the Funds and their agents. This makes the Funds’ identification of excessive trading transactions in the Funds through an omnibus account difficult and makes the elimination of excessive trading in the account impractical without the assistance of the intermediary. Although the Funds encourage intermediaries to take necessary actions to detect and deter excessive trading, some intermediaries may be unable or unwilling to do so, and accordingly, the Funds cannot eliminate completely the possibility of excessive trading.
Shareholders that invest through an omnibus account should be aware that they may be subject to the policies and procedures of their financial intermediary with respect to excessive trading in the Funds.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.A schedule of each Fund’s portfolio holdings, consisting of at least the names of the holdings, is generally available on a monthly basis with a 30-day lag and is posted under Full Holdings for each Fund at janushenderson.com/info. A complete schedule of each Fund’s portfolio holdings is also available in the annual and semiannual financial statements included in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. Each Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.
103 | Janus Investment Fund

Top Holdings.Each Fund’s top portfolio holdings, in order of position size and as a percentage of a Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.Each Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation), top/bottom issuers ranked by performance attribution, and specific portfolio level performance attribution information and statistics monthly with a 15-day lag. Top/bottom issuers may include the percentage of attribution to Fund performance, average Fund weighting, and other relevant data points.
The Adviser may exclude from publication on its websites all or any portion of portfolio holdings or change the time periods of disclosure as deemed necessary to protect the interests of the Janus Henderson funds. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Funds’ Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Funds’ portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Funds’ SAI.
Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with a Fund) is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with a Fund) is responsible for providing annual and semiannual reports of the Funds that you have authorized for investment. Please contact your financial intermediary or plan sponsor (or the Adviser) to obtain these reports. The Funds’ fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor (or the Adviser, if you hold Class N Shares directly with a Fund) is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor (or the Adviser) is unable to locate the shareholder, then the financial intermediary or plan sponsor (or the Adviser) is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Financial highlights
The financial highlights tables are intended to help you understand the Funds’ financial performance for each fiscal period shown. Items “Net asset value, beginning of period” through “Net asset value, end of period” reflect financial results for a single Fund Share. The gross expense ratio reflects expenses prior to any expense offset arrangement and waivers (reimbursements), if applicable. The net expense ratio reflects expenses after any expense offset arrangement and waivers (reimbursements), if applicable. The information for the Funds for the fiscal periods ended June 30 has been audited by PricewaterhouseCoopers LLP, whose report, along with the Funds’ financial statements, is included in each Fund’s Form N-CSR and is incorporated by reference into the SAI.
The total returns in the tables represent the rate that an investor would have earned (or lost) on an investment in the Shares of the Funds (assuming reinvestment of all dividends and distributions).

Appendix A – intermediary sales charge waivers and discounts
AMERIPRISE FINANCIAL
The following information is provided by Ameriprise Financial:
Sales Charge Reductions and Waivers Available from Certain Financial Intermediaries
The availability of certain sales charge reductions and waivers will depend on whether you purchase fund shares directly from the fund or through a financial intermediary. Financial intermediaries may have different policies and procedures regarding the availability of front-end sales load reductions or waivers or CDSC waivers, which are described below. In all instances, it is the investor’s responsibility to notify the fund or the investor’s financial intermediary at the time of purchase of any relationship or other facts qualifying the investor for sales charge reductions or waivers. For reductions or waivers not available through a particular financial intermediary, investors will have to purchase fund shares directly through another financial intermediary to receive these reductions or waivers.
*********
Ameriprise Financial
Front-end sales charge reductions on Class A shares purchased through Ameriprise Financial
Shareholders purchasing Class A shares of the fund through an Ameriprise Financial platform or account are eligible only for the following sales charge reductions, which may differ from those disclosed elsewhere in this prospectus or the SAI. Such shareholders can reduce their initial sales charge on the purchase of Class A shares as follows:
Transaction size breakpoints, as described in this prospectus or the SAI.
Rights of accumulation (ROA), as described in this prospectus or the SAI.
Letter of intent, as described in this prospectus or the SAI.
Front-end sales charge waivers on Class A shares purchased through Ameriprise Financial
Shareholders purchasing Class A shares of the fund through an Ameriprise Financial platform or account are eligible only for the following sales charge waivers, which may differ from those disclosed elsewhere in this prospectus or the SAI. Such shareholders may purchase Class A shares at NAV without payment of a sales charge as follows:

For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs or SAR-SEPs.
shares purchased through reinvestment of capital gains and dividend reinvestment when purchasing shares of the same fund (but not any other fund within the same fund family).
shares exchanged from Class C shares of the same fund in the month of or following the seven-year anniversary of the purchase date. To the extent that this prospectus elsewhere provides for a waiver with respect to such shares following a shorter holding period, that waiver will apply to exchanges following such shorter period. To the extent that this prospectus elsewhere provides for a waiver with respect to exchanges of Class C shares for load waived shares, that waiver will also apply to such exchanges.
shares purchased by employees and registered representatives of Ameriprise Financial or its affiliates and their immediate family members.
shares purchased by or through qualified accounts (including IRAs, Coverdell Education Savings Accounts, 401(k)s, 403(b) TSCAs subject to ERISA and defined benefit plans) that are held by a covered family member, defined as an Ameriprise Financial advisor and/or the advisor’s spouse, advisor’s lineal ascendant (mother, father, grandmother, grandfather, great grandmother, great grandfather), advisor’s lineal descendant (son, step-son, daughter, step-daughter, grandson, granddaughter, great grandson, great granddaughter) or any spouse of a covered family member who is a lineal descendant.
shares purchased from the proceeds of redemptions from another fund in the same fund family, provided (1) the repurchase occurs within 90 days following the redemption, (2) the redemption and purchase occur in the same account, and (3) redeemed shares were subject to a front-end or deferred sales load (i.e. Rights of Reinstatement).
CDSC waivers on Class A and C shares purchased through Ameriprise Financial
144 | Janus Investment Fund

Fund shares purchased through an Ameriprise Financial platform or account are eligible only for the following CDSC waivers, which may differ from those disclosed elsewhere in this prospectus or the SAI:
redemptions due to death or disability of the shareholder
shares sold as part of a systematic withdrawal plan as described in this prospectus or the SAI
redemptions made in connection with a return of excess contributions from an IRA account
shares purchased through a Right of Reinstatement (as defined above)
redemptions made as part of a required minimum distribution for IRA and retirement accounts pursuant to the Internal Revenue Code
EDWARD JONES
The following information is provided by Edward D. Jones & Co., L.P. (“Edward Jones”):
Policies Regarding Transactions Through Edward Jones
Effective on or after January 1, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the same fund family, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.
Breakpoints
Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.
Rights of Accumulation (“ROA”)
The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.
The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.
ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).
Letter of Intent (“LOI”)
Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.
If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.
145 | Janus Investment Fund

Sales Charge Waivers
Sales charges are waived for the following shareholders and in the following situations:
Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate.

The Right of Reinstatement excludes systematic or automatic transactions including, but not limited to, purchases made through payroll deductions, liquidations to cover account fees, and reinvestments from non-mutual fund products.
Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.
Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.
Purchases of Class 529-A shares through a rollover from either another education savings plan or a security used for qualified distributions.
Purchases of Class 529 shares made for recontribution of refunded amounts.

The death or disability of the shareholder.
Systematic withdrawals with up to 10% per year of the account value.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Funds may invest, as well as some general investment terms. The Funds may invest in these instruments to the extent permitted by their investment objectives and policies. The Funds are not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Bank loans include institutionally-traded floating and fixed-rate debt securities generally acquired as a participation interest in or assignment of a loan originated by a lender or financial institution. Assignments and participations involve credit, interest rate, and liquidity risk. Interest rates on floating rate securities adjust with interest rate changes and/or issuer credit quality.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Collateralized Loan Obligations (“CLOs”) are a type of structured credit, which is a sector of the fixed income market that also includes asset-backed and mortgage- backed securities. Typically organized as a trust or other special purpose vehicle, a CLO issues debt and equity interests and uses the proceeds from this issuance to acquire a portfolio of bank loans made primarily to businesses that are rated below investment grade.
Collateralized Mortgage Obligations (“CMOs”) are a type of mortgage-backed security that are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams (tranches) with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches are frequently referred to as “mortgage derivatives” and may be extremely sensitive to changes in interest rates. The issuer of a series of CMOs may elect to be treated as a Real Estate Mortgage Investment Conduit (“REMIC”). A REMIC is a CMO that qualifies for special tax treatment and invests in certain mortgages principally secured by interests in real property and other permitted investments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. A Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Common stocks are equity securities representing shares of ownership in a company and usually carry voting rights and earn dividends. Unlike preferred stock, dividends on common stock are not fixed but are declared at the discretion of the issuer’s board of directors.
Convertible securities are preferred stocks or bonds that pay a fixed dividend or interest payment and are convertible into common stock at a specified price or conversion ratio.
Credit Risk Transfer Securities (“CRTs”) are unguaranteed and unsecured fixed or floating rate general obligations that are commonly issued by government sponsored enterprises. CRTs are not directly linked to or backed by the underlying mortgage loans, so investors such as a Fund have no direct recourse to the underlying mortgage loans in the event of a default.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Depositary receipts are receipts for shares of a foreign-based corporation that entitle the holder to dividends and capital gains on the underlying security. Receipts include those issued by domestic banks (American Depositary Receipts), foreign banks (Global or European Depositary Receipts), and broker-dealers (depositary shares).
Duration is a measurement of price sensitivity to interest rate changes. Unlike average maturity, duration reflects both principal and interest payments. Generally, the higher the coupon rate on a bond, the lower its duration will be. The duration of a bond portfolio is calculated by averaging the duration of bonds held by a Fund with each duration “weighted” according to the percentage of net assets that it represents. Because duration accounts for interest payments, a Fund’s duration is usually shorter than its average maturity. Securities with longer durations tend to be more sensitive to changes in interest rates, and are usually more volatile than securities with shorter duration. For example, the price of a bond portfolio with an average duration of five years would be expected to fall approximately 5% if interest rates rose by one percentage point. A Fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise.

Equity securities generally include domestic and foreign common stocks; preferred stocks; securities convertible into common stocks or preferred stocks; warrants to purchase common or preferred stocks; and other securities with equity characteristics.
Exchange-traded funds (“ETFs”) are typically open-end investment companies, which may seek to track the performance of a specific index or be actively managed. ETFs are traded on a national securities exchange at market prices that may vary from the net asset value of their underlying investments.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
High-yield bonds are bonds that are rated below investment grade by the primary rating agencies (i.e., BB+ or lower by Standard & Poor’s and Fitch, or Ba1 or lower by Moody’s). Other terms commonly used to describe such bonds include “lower rated bonds,” “non-investment grade bonds,” and “junk bonds.”
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
Mortgage dollar rolls are transactions in which a Fund sells a mortgage-related security, such as a security issued by Government National Mortgage Association, to a dealer and simultaneously agrees to purchase a similar security (but not the same security) in the future at a predetermined price. A “dollar roll” can be viewed as a collateralized borrowing in which a Fund pledges a mortgage-related security to a dealer to obtain cash.
Municipal securities are bonds or notes issued by a U.S. state or political subdivision. A municipal security may be a general obligation backed by the full faith and credit (i.e., the borrowing and taxing power) of a municipality or a revenue obligation paid out of the revenues of a designated project, facility, or revenue source.
Pass-through securities are shares or certificates of interest in a pool of debt obligations that have been repackaged by an intermediary, such as a bank or broker-dealer.
Passive foreign investment companies (“PFICs”) are any foreign corporations which generate certain amounts of passive income or hold certain amounts of assets for the production of passive income. Passive income includes dividends, interest, royalties, rents, and annuities. To avoid taxes and interest that a Fund must pay if these investments are profitable, the Fund may make various elections permitted by the tax laws. These elections could require that a Fund recognize taxable income, which in turn must be distributed, before the securities are sold and before cash is received to pay the distributions.
Pay-in-kind bonds are debt securities that normally give the issuer an option to pay cash at a coupon payment date or give the holder of the security a similar bond with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.
Preferred stocks are equity securities that generally pay dividends at a specified rate and have preference over common stock in the payment of dividends and liquidation. Preferred stock generally does not carry voting rights.
Private placements are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies.
Real estate investment trust (“REIT”) is an investment trust that operates through the pooled capital of many investors who buy its shares. Investments are in direct ownership of either income property or mortgage loans. A REIT may be listed on an exchange or traded over-the-counter.
Rule 144A securities are securities that are not registered for sale to the general public under the Securities Act of 1933, as amended, but that may be resold to certain institutional investors.
Step coupon bonds are issued and traded at a discount from their face value and pay coupon interest that increases or decreases over the life of the bond. The discount from the face amount or par value depends on the time remaining until cash payments begin, prevailing interest rates, liquidity of the security and the perceived credit quality of the issuer.
152 | Janus Investment Fund

“To be announced” or “TBA” commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities, for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate, and mortgage terms. At the time the TBA commitment is made, the transaction is recorded and thereafter the value of such securities is reflected each day in determining a Fund’s net asset value. Because a Fund is generally not required to pay for the security until the settlement date, if the Fund remains substantially fully invested at a time when TBA commitment purchases are outstanding, the purchases may result in a form of leverage.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Warrants are securities, typically issued with preferred stock or bonds, which give the holder the right to buy a proportionate amount of common stock at a specified price. The specified price is usually higher than the market price at the time of issuance of the warrant. The right may last for a period of years or indefinitely.
Zero coupon bonds are debt obligations that do not pay regular cash interest payments at regular intervals, but are issued at a discount from face value. The discount approximates the total amount of interest the security will accrue from the date of issuance to maturity. The market value of these securities generally fluctuates more in response to changes in interest rates than interest-paying securities.
Futures, Options, and Other Derivatives
Credit default swaps are a specific kind of counterparty agreement that allows the transfer of third party credit risk from one party to the other. One party in the swap is a lender and faces credit risk from a third party, and the counterparty in the credit default swap agrees to insure this risk in exchange for regular periodic payments.
Derivatives are instruments that have a value derived from, or directly linked to, an underlying asset (stock, bond, commodity, currency, interest rate or market index). Types of derivatives can include, but are not limited to options, forward currency contracts, swaps, and futures contracts.
Equity-linked structured notes are derivative securities which are specially designed to combine the characteristics of one or more underlying securities and their equity derivatives in a single note form. The return and/or yield or income component may be based on the performance of the underlying equity securities, an equity index, and/or option positions. Equity-linked structured notes are typically offered in limited transactions by financial institutions in either registered or non-registered form.
Equity swaps involve the exchange by two parties of future cash flow (e.g., one cash flow based on a referenced interest rate and the other based on the performance of stock or a stock index).
Forward contracts are contracts to purchase or sell a specified amount of a financial instrument for an agreed upon price at a specified time. Forward contracts are not currently exchange-traded and are typically negotiated on an individual basis. A Fund may enter into forward currency contracts for investment purposes or to hedge against declines in the value of securities denominated in, or whose value is tied to, a currency other than the U.S. dollar or to reduce the impact of currency appreciation on purchases of such securities. It may also enter into forward contracts to purchase or sell securities or other financial indices.
153 | Janus Investment Fund

Futures contracts are contracts that obligate the buyer to receive and the seller to deliver an instrument or money at a specified price on a specified date. A Fund may buy and sell futures contracts on foreign currencies, securities, and financial indices including indices of U.S. Government, foreign government, equity, or fixed-income securities. Futures contracts are standardized and traded on designated exchanges.
Indexed/structured securities are typically short- to intermediate-term debt securities whose value at maturity or interest rate is linked to currencies, interest rates, equity securities, indices, commodity prices, or other financial indicators. Such securities may be positively or negatively indexed (e.g., their value may increase or decrease if the reference index or instrument appreciates). Indexed/structured securities may have return characteristics similar to direct investments in the underlying instruments and may be more volatile than the underlying instruments.
Inflation index swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments or an exchange of floating rate payments based on two different reference indices). By design, one of the reference indices is an inflation index, such as the Consumer Price Index.
Interest rate swaps involve the exchange by two parties of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments).
Inverse floaters are debt instruments whose interest rate bears an inverse relationship to the interest rate on another instrument or index. For example, upon reset, the interest rate payable on the inverse floater may go down when the underlying index has risen. Certain inverse floaters may have an interest rate reset mechanism that multiplies the effects of change in the underlying index. Such mechanism may increase the volatility of the security’s market value.
Options are the right, but not the obligation, to buy or sell a specified amount of securities or other assets on or before a fixed date at a predetermined price. A Fund may purchase and write put and call options on securities, securities indices, and foreign currencies. A Fund may purchase or write such options individually or in combination.
Total return swaps involve an exchange by two parties in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of an underlying asset, which includes both the income it generates and any capital gains over the payment period. A fixed-income total return swap may be written on many different kinds of underlying reference assets, and may include different indices for various kinds of debt securities (e.g., U.S. investment grade bonds, high-yield bonds, or emerging market bonds).
Other Investments, Strategies, and/or Techniques
Cash sweep program is an arrangement in which a Fund’s uninvested cash balance is used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the Investment Company Act of 1940, as amended, that govern the operation of money market funds at the end of each day.
Market capitalization is the most commonly used measure of the size and value of a company. It is computed by multiplying the current market price of a share of the company’s stock by the total number of its shares outstanding. Market capitalization is an important investment criterion for certain funds, while others do not emphasize investments in companies of any particular size.
Net long is a term used to describe when a Fund’s assets committed to long positions exceed those committed to short positions.
Repatriation is the ability to move liquid financial assets from a foreign country to an investor’s country of origin.
Repurchase agreements involve the purchase of a security by a Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
Short sales in which a Fund may engage may be either “short sales against the box” or other short sales. Short sales against the box involve selling short a security that a Fund owns, or the Fund has the right to obtain the amount of the security sold short at a specified date in the future. A Fund may also enter into a short sale to hedge against anticipated declines in the market price of a security or to reduce portfolio volatility. If the value of a security sold short increases prior to the scheduled delivery date, the Fund loses the opportunity to participate in the gain.
154 | Janus Investment Fund

When-issued, delayed delivery, and forward commitment transactions generally involve the purchase of a security with payment and delivery at some time in the future – i.e., beyond normal settlement. New issues of stocks and bonds, private placements, and U.S. Government securities may be sold in this manner.

Principal investment strategies
The Fund pursues its investment objectives by primarily investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. Government securities and repurchase agreements that are collateralized by U.S. Government securities.
The Fund operates as a “government money market fund” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended. As a government money market fund, the Fund pursues its investment objectives by normally investing at least 99.5% of its total assets in cash, U.S. Government securities, and/or repurchase agreements that are collateralized fully (i.e., collateralized by cash and/or government securities). The Fund’s investments in U.S. Government securities may include obligations issued and/or guaranteed as to principal and interest by the United States Government or by its agencies and instrumentalities, and repurchase agreements secured by such obligations. Although U.S. Government agencies and instrumentalities may be chartered or sponsored by Acts of Congress, their securities are not issued by, and may not be guaranteed by (i.e., backed by the full faith and credit of), the U.S. Treasury. Some government agency and instrumentality securities not backed by the full faith and credit of the United States are supported by the issuer’s ability to borrow from the U.S. Treasury, some are supported only by the credit of the issuer, and some are supported by the United States in some other way. The Fund’s investments in securities issued by U.S. Government agencies and instrumentalities may be significant.
2 | Janus Henderson Government Money Market Fund

The Fund will:
invest in high-quality, short-term money market instruments that present minimal credit risks, as determined by the Adviser
invest only in U.S. dollar-denominated instruments that have a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended)
maintain a dollar-weighted average portfolio maturity of 60 days or less and maintain a dollar-weighted average portfolio life (portfolio maturity measured without reference to any maturity shortening provisions of adjustable rate securities by reference to their interest rate reset dates) of 120 days or less
As a government money market fund, the Board of Trustees has determined not to subject the Fund to a liquidity fee on Fund redemptions. Please note that the Board of Trustees has reserved the ability to change this determination with respect to liquidity fees, but only after providing appropriate prior notice to shareholders.
Principal investment risks
Money Market Risk.You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Adviser is not required to reimburse the Fund for losses, and you should not expect that the Adviser will provide financial support to the Fund at any time, including during periods of market stress. Accordingly, if the value of Fund Shares were to fall below $1.00 per share, there is no guarantee that the Adviser or its affiliates would protect the Fund or redeeming shareholders against any loss of principal.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations (potentially even the U.S. Government). The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Interest Rate Risk.Although the Fund seeks to invest only in high-quality, short-term money market instruments, there is a risk that the value of the securities it holds will fall as a result of the changes in interest rates. Rising interest rates could cause the value of the Fund’s investments to decline, and a decline in interest rates is likely to cause the Fund’s yield to decline. During periods of unusually low or negative interest rates, the Fund’s yield may approach or fall below zero. Such low interest rate environments may prevent the Fund from providing a positive yield or could impair the Fund’s ability to maintain the value of your investment at $1.00 per share. Over time, the real value of the Fund’s yield may be eroded by inflation.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield.
Collateral Risk.With respect to collateral received in repurchase transactions or other investments, the Fund may have significant exposure to government agencies not secured by the full faith and credit of the United States. Such exposure, depending on market conditions, could have a negative impact on the Fund, including minimizing the value of any collateral.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s
3 | Janus Henderson Government Money Market Fund

financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.
U.S. Government Securities Risk.Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. American Cancer Society Support – Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for American Cancer Society Support – Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If American Cancer Society Support – Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of American Cancer Society Support – Class D Shares reflects the fees and expenses of American Cancer Society Support – Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table shows how the Fund’s returns over different periods average out. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
With respect to share classes not offered in this Prospectus, the Fund or its distributor (or its affiliates) pay select broker-dealer firms or other financial intermediaries for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing a broker-dealer or other intermediary or a salesperson to recommend the Fund over another investment or to recommend one share class over another.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders through the management fee and the administration fee paid to the Adviser.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses” for the Fund include a class-level administration fee of 0.20% of the average daily net assets of American Cancer Society Support – Class D Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping and registration functions and also to pay for costs such as shareholder servicing and custody.
The Adviser has contractually agreed to waive and/or reimburse the Fund’s “Total Annual Fund Operating Expenses” to the extent such expenses (excluding brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) exceed 0.33% for at least a one-year period through December 31, 2025. The expense limit is described in the “Expense Limitation” section of this Prospectus.
The Adviser may voluntarily waive and/or reimburse fees to the extent necessary to assist the Fund in attempting to maintain a yield of at least 0.00%. Any waivers and reimbursements are voluntary and could change or be terminated at any time at the discretion of the Adviser. There is no guarantee that the Fund will maintain a positive yield.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, the Fund will provide shareholders with at least 60 days’ notice prior to changing the 80% investment policy. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
This section takes a closer look at investment strategies and general policies that apply to the Fund. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. The Fund is subject to certain specific Securities and Exchange Commission (“SEC”) rule requirements. Among other things, the Fund is limited to investing in U.S. dollar-denominated instruments with a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended) that are determined to present minimal credit risk.
Security Selection
In selecting securities for the Fund’s portfolio, portfolio management focuses on securities that offer liquidity and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.
Demand Features
Demand features give the Fund the right to resell securities at specified periods prior to their maturity dates. Demand features may shorten the life of a variable or floating rate security or preferred stock, enhance the instrument’s credit quality, and provide a source of liquidity. Demand features are often issued by third party financial institutions, generally domestic and foreign banks. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the banks supporting the Fund’s investments. This will result in exposure to risks pertaining to the banking
7 | Janus Investment Fund

industry, including the foreign banking industry. Brokerage firms and insurance companies also provide certain liquidity and credit support.
Liquidity
The Fund has adopted liquidity requirements (measured at the time of purchase) as noted:
Daily liquidity.The Fund will invest at least 25% of its total assets in “daily liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within one business day, and/or amounts receivable and due unconditionally within one business day on pending sales of portfolio securities.
Weekly liquidity.The Fund will invest at least 50% of its assets in “weekly liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within five business days.
The Fund will limit its investments in illiquid securities to 5% or less of its total assets.
Mortgage- and Asset-Backed Securities
The Fund may purchase fixed or variable rate commercial or residential mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees are backed by the full faith and credit of the U.S. Government, which means that the U.S. Government guarantees that the interest and principal will be paid when due. Fannie Mae and Freddie Mac securities, as well as the securities of other government or government-related entities, are not backed by the full faith and credit of the U.S. Government.
Participation Interests
A participation interest gives the Fund a proportionate, undivided interest in underlying debt securities and usually carries a demand feature.
Repurchase Agreements
The Fund may enter into collateralized repurchase agreements by cash or U.S. Government securities. Repurchase agreements are transactions in which the Fund purchases securities and simultaneously commits to resell those securities to the seller at an agreed-upon price on an agreed-upon future date. The repurchase price reflects a market rate of interest.
U.S. Government Securities
The Fund may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer.
Variable and Floating Rate Securities
The Fund may purchase variable and floating rate demand notes of U.S. Government issuers. These securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to an interest rate index or market interest rate. Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness.
Risks of the Fund
The value of your investment may vary over time, and you may lose money by investing in the Fund. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
8 | Janus Investment Fund

Commercial Paper Risk.Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations. The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield. Further, regardless of how well securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions that have a significant effect on issuers. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. In the event the underlying loans are not paid, the securities’ issuer could be forced to sell the assets and recognize losses on such assets, which could impact the Fund’s yield and return. Mortgage- and asset-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. Investments in mortgage- and asset-backed securities are subject to both extension risk, where during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally expected, and prepayment risk, where during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated. These risks may reduce the Fund’s returns. In addition, investments in certain mortgage- and
9 | Janus Investment Fund

asset-backed securities may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities.
Participation Interests Risk.If the Fund purchases a participation interest, it typically will have a contractual relationship with the lender and not with the borrower. The Fund may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender, or any other intermediate participant. The Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender and only upon receipt by the lender of the payments from the borrower. The failure by the Fund to receive scheduled interest or principal payments may adversely affect the income of the Fund and may likely reduce the value of its assets, which would be reflected by a reduction in the Fund’s net asset value.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security. While it is not possible to eliminate all risks from these transactions, it is the policy of the Fund to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory. There is no guarantee that the Adviser’s analysis of the creditworthiness of the counterparty will be accurate, and the underlying collateral involved in the transaction can expose the Fund to additional risk regardless of the creditworthiness of the parties involved in the transaction.
U.S. Government Securities Risk.Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets. Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Board of Trustees (“Trustees”), to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Adviser generally pays the salaries, fees, and expenses of Fund officers with respect to services provided to the Fund, although some expenses related to compensation payable to the Fund’s Chief Compliance Officer and compliance staff are shared with the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs other expenses, including legal and auditing fees and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund pays.
The following table reflects the Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual investment advisory fee rate paid by the Fund to the Adviser (net of fee waivers). The rate shown is a fixed rate based on the Fund’s average daily net assets.

American Cancer Society Support
The Adviser will donate from the Adviser’s own resources, an amount representing 50% of the Adviser’s quarterly management fee revenue attributable to the Fund, net of any fee waivers and/or expense reimbursements, to the American Cancer Society® (“ACS”) in connection with ACS’s agreement to license the use of its name and trademarks to the Adviser. The Adviser will make annual minimum contributions to ACS of $1 million from 2024 to 2027, and in each year thereafter to the extent this arrangement continues. The Adviser’s donation may result in a tax benefit for the Adviser, but will not
11 | Janus Investment Fund

result in a tax benefit for shareholders. The ACS does not endorse any service or product. Shares of the Fund are not sponsored, endorsed, or promoted by the ACS, and the ACS is not an investment adviser or service provider to the Fund, Trust, or Adviser.
A discussion regarding the basis for the Trustees’ approval of the Fund’s investment advisory agreement is included in the Fund’s semiannual report (for the period ended December 31, 2023) and in the Fund’s financial statements (for the period ended June 30, 2024, and moving forward). You can request the Fund’s semiannual reports or financial statements (as they become available), free of charge, by contacting a Janus Henderson representative at 1-800-525-3713. This information is also available, free of charge, at janushenderson.com/reports.
Administration fee
The Fund pays an administration fee of 0.20% of the average daily net assets of American Cancer Society Support – Class D Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping, fund accounting, preparation of reports and prospectuses distributed to current shareholders, and registration functions. This administration fee also covers expenses including, but not limited to, custody, transfer agency, shareholder servicing, and provision of office facilities and personnel necessary to carry on the business of the Fund.
Expense limitation
The Adviser has contractually agreed to waive and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) exceed 0.33% for at least a one-year period through December 31, 2025. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. For information about how the expense limit affects the total expenses of the Fund, see the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus.
Portfolio management
Janus Henderson Government Money Market Fund
Effective February 1, 2025, Co-Portfolio Managers Andrew Forman and Garrett Strum will be responsible for the day-to-day management of the Fund. Mr. Strum, as Lead Portfolio Manager, has the authority to exercise final decision-making on the overall portfolios.
Andrew Forman is Co-Portfolio Manager of Janus Henderson Government Money Market Fund, which he has co-managed since February 2025. He is also Portfolio Manager of other Janus Henderson accounts. Mr. Forman joined the Adviser in 2013. He holds a Bachelor of Arts degree in Economics with a minor in Atmospheric and Oceanic Sciences from the University of Colorado.
Garrett Strum is Executive Vice President and Lead Portfolio Manager of Janus Henderson Government Money Market Fund, which he has managed or co-managed since May 2017. He is also Portfolio Manager of other Janus Henderson accounts and performs duties as an analyst. Mr. Strum holds a Bachelor of Science degree in Business with concentrations in Finance and Real Estate from Colorado State University.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that the Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to the Fund. Purchases and
12 | Janus Investment Fund

redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.
13 | Janus Investment Fund

Other information
CLOSED FUND POLICIES
The Fund may limit sales of its Shares to new investors. If sales of the Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Fund
The Fund is distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Dividends representing substantially all of the net investment income and any net realized gains on sales of securities are declared daily (Saturdays, Sundays, and holidays included) and distributed as of the last business day of each month. If a month begins on a Saturday, Sunday, or holiday, dividends for those days are declared and distributed at the end of the preceding month.
Purchase orders received prior to 4:00 p.m. (New York time) on a bank business day (a day when both the New York Stock Exchange (“NYSE”) and the Federal Reserve Banks are open) will begin to accrue dividends on the following bank business day.
Redemption requests received prior to 4:00 p.m. (New York time) on a bank business day will receive that day’s dividends. Proceeds of such redemption will normally be sent on the next bank business day.
The Fund reserves the right to require purchase and redemption requests and payments prior to these times on days when the bond markets or NYSE close early. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early).
For your convenience, distributions of dividends and capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus Henderson representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
Distribution Options
When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janushenderson.com/individual, by calling a Janus Henderson representative, or by writing to the Fund at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Fund offers the following options:
Reinvestment Option.You may reinvest your income dividends and capital gains distributions in additional shares.
Cash Option.You may receive your income dividends and capital gains distributions in cash.
Redirect Option.You may direct your dividends to purchase shares of another Janus Henderson fund.
The Fund reserves the right to reinvest uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Shareholder Services and Account Policies.”
TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term
15 | Janus Investment Fund

capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”).
Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, the Janus Henderson funds will report cost basis information to you and to the IRS. The Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
16 | Janus Investment Fund

The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.

This section will help you become familiar with the different types of accounts you can establish with the Adviser. It also explains in detail the wide array of services and features you can establish on your account, as well as describes account policies and fees that may apply to your account. Account policies (including fees), services, and features may be modified or discontinued without shareholder approval or prior notice.
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.

The Fund reserves the right to change the amount of these minimums from time to time or to waive them in whole or in part. Participants in certain retirement plans, including but not limited to, Janus Henderson prototype Money Purchase Pension and Profit Sharing plans, SEP IRAs, SARSEP IRAs, or outside qualified retirement plans, may not be subject to the stated minimums. Employees of JHG and its subsidiaries may open Fund accounts for $100.
**
All states have repealed UGMA statutes, enacting UTMA statutes in their place. Existing UGMA accounts established before the date of repeal are grandfathered using the original UGMA age of termination.
Minimum Investment Requirements
Due to the proportionately higher costs of maintaining small accounts, the Fund reserves the right to deduct an annual $25 minimum balance fee per Fund account (paid to the Transfer Agent) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You will receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.
Available Incentive Programs
Bonus Program for Taxable Account Purchases and Tax-Advantaged Account Transfers/Rollovers
Through the Transfer Agent’s Bonus Program, the Transfer Agent will pay a bonus of up to $2,500 to you for making certain eligible purchases of Fund shares in taxable accounts or transfers/rollovers from a non-Janus Henderson fund account into a Janus Henderson fund tax-advantaged account. The Bonus Program is valid with an eligible purchase or transfer/rollover of $20,000 or more. If you meet the eligibility requirements for the Bonus Program and enroll in it, the Transfer Agent will deposit a bonus payment into your Fund account within approximately 30 days after the deposit of eligible funds in good order and receipt of a signed contract governing the Bonus Program. An investor must keep the eligible purchase in the account for a period of 360 calendar days in order to retain the bonus payment. Any sale of the qualifying purchase amount (in whole or in part), transfer, or closure of the account within the 360 calendar day period may result in forfeiture of the bonus payment. Any decline in an account’s value due solely to market value fluctuations will not result in the forfeiture of the bonus payment. Only taxable account purchases or transfers/rollovers to tax-advantaged accounts that are made on or after January 1, 2024 through December 31, 2024 are eligible for a bonus payment. The eligible period for the Bonus Program may be extended beyond this time frame at the sole discretion of the Transfer Agent. Before enrolling in the Bonus Program, consult with your tax advisor about the appropriate tax treatment for the bonus offer and any tax implications associated with the receipt of a bonus payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke this Bonus Program at any time without advance notice.
You can request more information about the Transfer Agent’s Bonus Program and eligibility requirements for taxable accounts by contacting a Janus Henderson representative at 1-800-525-3713 or by visiting www.janushenderson.com/bonus. You can request more information about the Bonus Program for tax-advantaged account transfers/rollovers by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Contribution Match Payments
Investors that transfer/rollover assets from a non-Janus Henderson fund account into a tax-advantaged account are also eligible for the Transfer Agent’s Contribution Match Program. To receive a Transfer Agent’s Contribution Match payment, (i) the value of your tax-advantaged account must remain equal to or greater than the value of the eligible transfer/rollover (but not including any losses due solely to market value fluctuations) for 12 months following the receipt of your transfer/rollover in good order and receipt of a signed contract governing the Contribution Match Program, and (ii) you must provide instructions to the Transfer Agent on how to invest these payments. The Transfer Agent’s Contribution Match payments will commence at the end of the first quarter in 2025 following an eligible contribution during the first quarter of 2025 into a Janus Henderson fund tax-advantaged account. The eligible period for the Transfer Agent’s Contribution Match payments may be extended beyond this time frame at the sole discretion of the Transfer Agent. The Transfer Agent will match a percentage of these contributions based on the aggregate value of eligible 2024 rollover or asset transfer amounts, and provide a matching contribution in an amount up to ten percent of your contribution. Before enrolling in the Contribution Match Program, consult with your tax advisor about the appropriate tax treatment for the Transfer Agent’s Contribution Match payments and any tax implications associated with the receipt of a Contribution Match payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Contribution Match Program at any time without advance notice.

You can request more information about the Contribution Match Program and eligibility requirements by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Ready. Invest. Go. Program
New investors creating a new Janus Henderson direct account are eligible to participate in the Transfer Agent’s Ready. Invest. Go. Program. After the new investor has completed the required Ready. Invest. Go. Program Contract, the Transfer Agent will fund the $100 initial investment required for new investors, provided that new investors enroll in Janus Henderson’s automatic investment program in an amount equal to at least $50 per month. New investors will forfeit the $100 bonus contributed by the Transfer Agent if their account is closed or if their automatic monthly investment program payment is terminated within two years from the date the initial investment was made. Investor-initiated amounts outside of the initial investment are redeemable at any time at net asset value. Before enrolling in the Ready. Invest. Go. Program, new investors should consult with their tax advisor about the appropriate tax treatment for participating in the Ready. Invest. Go. Program and any tax implications associated with the receipt of the $100 initial investment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Ready. Invest. Go. Program at any time without advance notice.
You can request more information about the Transfer Agent’s Ready. Invest. Go. Program by contacting a Janus Henderson representative at 1-800-525-3713.

Pricing of fund shares
The per share net asset value (“NAV”) for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the NYSE (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early). The value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after a request is received in good order by the Fund or its agents.
22 | Janus Investment Fund

The Fund’s portfolio securities are valued at amortized cost, which approximates market value. Amortized cost valuation involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity (or such other date as permitted by Rule 2a-7) of any discount or premium. If fluctuating interest rates cause the market value of the Fund’s portfolio to deviate more than 1/2 of 1% from the value determined on the basis of amortized cost, the Trustees will consider whether any action, such as adjusting the NAV to reflect current market conditions, should be initiated to prevent any material dilutive effect on shareholders.
Policies in Relation to Transactions
All requests, including but not limited to, exchanges between the Fund and other Janus Henderson funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus Henderson’s P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase. The Fund reserves the right to require purchase and/or redemption requests prior to this time on days when the bond markets or the NYSE close early. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early). Please call a Janus Henderson representative for details.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary and when considering which share class of a fund is most appropriate.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
23 | Janus Investment Fund

From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you.
Paying for shares
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to buy shares.
Please note the following when purchasing Shares:
Cash, credit cards, third party checks (with certain limited exceptions), travelers cheques, credit card checks, line of credit checks, or money orders will not be accepted.
All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted non-U.S. bank.
Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.
When purchasing Shares through the Automatic Investment Program, your automatic investment selection(s) will generally be active within three days following receipt of your authorization for the date and amount you specify. If no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. If the balance in the Janus Henderson fund account you are buying into falls to zero as the result of a redemption, exchange, or minimum balance fee, your Automatic Investment Program will be discontinued.
We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Fund by submitting good funds via another method accepted by the Fund (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading.
If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as applicable, will be invested in Janus Henderson Government Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus Henderson to (i) buy shares of another Janus Henderson fund or (ii) sell shares of Janus Henderson Government Money Market Fund and return the proceeds (including any dividends earned) to you, Janus Henderson will treat your inaction as approval of the purchase of Janus Henderson Government Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus Henderson for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Henderson Government Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Henderson Government Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will be automatically exchanged from Janus Henderson Government Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”
For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.
24 | Janus Investment Fund

If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and any losses incurred by the Fund as a result. The Fund may redeem shares held in your account to cover any losses it incurs if your purchase is cancelled.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), the Adviser is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, the Adviser may temporarily limit additional share purchases. In addition, the Adviser may close an account if it is unable to verify a shareholder’s identity. Please contact a Janus Henderson representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
The Fund has also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Fund is required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.
Exchanges
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Please note the following when exchanging Shares:
An exchange represents the redemption (or sale) of shares from the Fund and the purchase of shares of another fund, which may produce a taxable gain or loss in a non-retirement account.
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. The Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.
New regular Janus Henderson fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus Henderson fund account you are exchanging from is less than $2,500 ($100 for new regular Fund accounts with an automatic investment program of $50 per month). (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus Henderson fund account you are exchanging from is less than the stated minimum, you must exchange the entire balance. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
25 | Janus Investment Fund

New Janus Henderson fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
Exchanges between existing Janus Henderson fund accounts must meet the $50 subsequent investment requirement.
For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus Henderson fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.
The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
With certain exceptions, exchanges between Janus Henderson fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus Henderson fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.

Payment of redemption proceeds
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.
Next Day Wire Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.
ACH (Automated Clearing House) Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on or about the next bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.
By Check – Redemption proceeds will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.
By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus Henderson fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.
The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Generally, orders to sell Shares may be initiated at any time at janushenderson.com/individual, by telephone, or in writing. Certain accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Fund can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide
26 | Janus Investment Fund

alternate instructions, your proceeds will be invested in Shares of Janus Henderson Government Money Market Fund during the 15-day hold period.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. A temporary hold may also be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult has occurred, is occurring, has been attempted, or will be attempted, as described under “Temporary Suspension of Services.”

Large Shareholder Redemptions
Certain large shareholders, such as other funds, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Suspension of Redemptions
In the event the Fund’s market-based net asset value per share has deviated from the Fund’s amortized cost price per share, or the Fund’s Trustees, including a majority of Independent Trustees, determines that such a deviation is likely to occur, then the Trustees will take such action as they deem appropriate including, but not limited to, suspending redemptions and the payment of redemption proceeds, in order to facilitate the liquidation of the Fund. In addition, if the Fund’s weekly liquid assets fall below 10%, the Fund may cease honoring redemptions and liquidate at the discretion of the Trustees. Prior to
27 | Janus Investment Fund

suspending redemptions, the Fund would be required to notify the SEC of its decision to suspend redemptions and liquidate. If the Fund ceases honoring redemptions and makes a decision to liquidate, the Fund expects that it would notify shareholders on the Fund’s websites or by press release.
Written Instructions
To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus Henderson.” Requests or documents received in a language other than English may be inadvertently delayed or returned due to an inability to accurately translate the intended instructions. Please include the following information:
the name of the Janus Henderson fund(s) being redeemed or exchanged;
the account number(s);
the amount of money or number of shares being redeemed or exchanged;
the name(s) on the account;
the signature(s) of one or more registered account owners; and
your daytime telephone number.
Signature Guarantee
A signature guarantee for each registered account owner is required if any of the following is applicable:
You request a redemption by check above a certain dollar amount.
You would like a check made payable to anyone other than the shareholder(s) of record.
You would like a check mailed to an address that has been changed within 10 days of the redemption request.
You would like a check mailed to an address other than the address of record.
You would like your redemption proceeds sent to a bank account other than a bank account of record.
The Fund reserves the right to require a signature guarantee under other circumstances or to reject or delay a redemption on certain legal grounds.
A signature guarantee may be refused if any of the following is applicable:
It does not appear valid or in good form.
The transaction amount exceeds the surety bond limit of the signature guarantee.
The guarantee stamp has been reported as stolen, missing, or counterfeit.
How to Obtain a Signature Guarantee
A signature guarantee assures that a signature is genuine. The signature guarantee protects shareholders from unauthorized account transfers. The following financial institutions may guarantee signatures: banks, savings and loan associations, trust companies, credit unions, broker-dealers, and member firms of a national securities exchange. Call your financial institution to see if it has the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.The Fund is required to disclose its complete holdings in the annual and semiannual financial statements included in Form N-CSR. In addition, the Fund is required to disclose its complete holdings in a monthly report on Form N-MFP within 5 business days after each month end. Form N-CSR filings and Form N-MFP reports (i) are available on the SEC’s website at http://www.sec.gov and (ii) are available without charge, upon request, by calling a Janus Henderson representative at 1-800-525-3713 (toll free). Holdings are generally posted within 5 business days after each month end under Full Holdings for the Fund at janushenderson.com/reports.
Top Holdings.The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag.
28 | Janus Investment Fund

Other Information.The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation) and specific portfolio level performance attribution information and statistics monthly with a 15-day lag.
Full portfolio holdings will be available monthly and will remain on the Janus Henderson websites for at least 6 months on a rolling basis and will link to the Fund’s Form N-MFP filing available on the SEC website. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s SAI.
Shareholder services and account policies
Address Changes
For the easiest way to change the address on your account, visit janushenderson.com/individual. You may also call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Include the name of the Janus Henderson fund(s) you hold, the account number(s), the name(s) on the account, and both the old and new addresses. Certain options may be suspended for 10 days following an address change unless a signature guarantee is provided.
Bank Account Changes
For the easiest way to change your bank account of record or add new bank account information to your account, visit janushenderson.com/individual. You may also send a written request signed by the shareholder of record or by each shareholder of record if more than one. Certain accounts may require a written notice and, in some instances, bank privileges may not be available. If multiple account owners are named on the added bank account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.
You may revoke the authorization to use your bank account information at any time by visiting janushenderson.com/individual, or by sending a written request by mail (Janus Henderson, P.O. Box 219109, Kansas City, MO 64121-9109), or by telephone at 1-800-525-3713. Your request will be processed within a reasonable amount of time upon its receipt.
Check Writing Privilege
Check writing privileges are available for the Fund. Checkbooks will be issued to shareholders who have completed a Signature Draft Card, which is sent in the new account welcome package, or who call a Janus Henderson representative. (There is no check writing privilege for retirement accounts.) Your checkbook will be mailed approximately 10 days after the check writing privilege is requested. You may order checks any time at janushenderson.com/individual. Checks may be written for $250 or more per check. Purchases made by check or automated investment may not be redeemed by a redemption check until the 15-day hold period has passed. In addition, checks presented against uncollected or insufficient funds in the Fund may be returned unpaid. All checks written on the account must be signed by all account holders unless otherwise specified on the original application or the subsequent Signature Draft Card. The Fund reserves the right to terminate or modify the check writing privilege at any time. These checks may not be used to initiate online banking, bill payment, or other electronic debits from your Fund account.
Distributions
Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janushenderson.com/individual, call a Janus Henderson representative, or send a written request signed by one or more shareholder(s) of record.
Your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.
Involuntary Redemptions
The Fund reserves the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Fund. This includes, but is not limited to, accounts that the Fund or its agents
29 | Janus Investment Fund

believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.
Lost (Unclaimed/Abandoned) Accounts
It is important that the Fund maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund as undeliverable. Based upon statutory requirements for returned mail, the Adviser will attempt to locate the shareholder or rightful owner of the account. If the Adviser is unable to locate the shareholder, then the Adviser is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
Online and Telephone Transactions
You may initiate many transactions through janushenderson.com/individual or by calling Janus Henderson XpressLine. You may also contact a Janus Henderson representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please call a Janus Henderson representative. The Fund and its agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.
Your ability to access your account or transact business electronically may be impacted due to unexpected circumstances, such as system outages, or during periods of increased web activity. For example, periods of substantial market change or other unexpected events can contribute to high call volumes, which may delay your ability to reach a Janus Henderson representative by telephone.
If you experience difficulty transacting business with us through a particular method, please consider using an alternate method, such as visiting janushenderson.com/individual, calling Janus Henderson XpressLine, contacting a Janus Henderson representative by telephone, or sending written instructions to complete your transaction. Please remember that purchase, exchange, or redemption requests must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE in order to receive that day’s NAV.
Your account information, including online credentials, should be kept private, and you should immediately review any account statements that you receive from Janus Henderson. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus Henderson immediately about any transactions you believe to be unauthorized.
Registration Changes
To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janushenderson.com/individual or call a Janus Henderson representative for further instructions.
Statements, Reports, and Prospectuses
We will send you a confirmation upon the completion of individual account transactions. We will also send you quarterly account statements detailing financial transactions on open accounts processed year-to-date. Systematic transactions are confirmed on quarterly statements unless otherwise requested. Confirmations and quarterly account statements will be sent to the account address of record unless you have elected to receive online statements. The Fund reserves the right to charge a fee for additional account statement requests.
At account setup, or any time thereafter, you may elect (at janushenderson.com/edelivery) to discontinue physical delivery of quarterly account statements and/or confirmations, and instead receive an e-mail notification when they are available online. All statements are available online regardless of your delivery option elections (to view, you must first establish online access at janushenderson.com/individual).
The Fund produces shareholder reports semiannually, and updates its prospectus annually. You may elect to receive shareholder reports and prospectus updates electronically at janushenderson.com/edelivery. The Fund’s fiscal year ends June 30.
30 | Janus Investment Fund

Unless you instruct Janus Henderson otherwise by contacting a Janus Henderson representative, the Fund will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Fund receives your instructions.
Taxpayer Identification Number
On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Fund to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Fund for any penalty that the IRS may impose.
Temporary Suspension of Services
The Fund or its agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Fund may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Fund to redeem its Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.
In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (i) a natural person age 65 and older, or (ii) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests. We may not be aware of factors suggesting financial exploitation of a Specified Adult and may not be able to identify Specified Adults in all circumstances. Furthermore, we are not required to delay the disbursement of redemption proceeds and do not assume any obligation to do so.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Agency discount notes are U.S. Government securities that are issued by a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. The Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Other Investments, Strategies, and/or Techniques
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.

Principal investment strategies
The Fund pursues its investment objectives by primarily investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. Government securities and repurchase agreements that are collateralized by U.S. Government securities.
The Fund operates as a “government money market fund” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended. As a government money market fund, the Fund pursues its investment objectives by normally investing at least 99.5% of its total assets in cash, U.S. Government securities, and/or repurchase agreements that are collateralized fully (i.e., collateralized by cash and/or government securities). The Fund’s investments in U.S. Government securities may include obligations issued and/or guaranteed as to principal and interest by the United States Government or by its agencies and instrumentalities, and repurchase agreements secured by such obligations. Although U.S. Government agencies and instrumentalities may be chartered or sponsored by Acts of Congress, their securities are not issued by, and may not be guaranteed by (i.e., backed by the full faith and credit of), the U.S. Treasury. Some government agency and instrumentality securities not backed by the full faith and credit of the United States are supported by the issuer’s ability to borrow from the U.S. Treasury, some are supported only by the credit of the issuer, and some are supported by the United States in some other way. The Fund’s investments in securities issued by U.S. Government agencies and instrumentalities may be significant.

The Fund will:
invest in high-quality, short-term money market instruments that present minimal credit risks, as determined by the Adviser
invest only in U.S. dollar-denominated instruments that have a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended)
maintain a dollar-weighted average portfolio maturity of 60 days or less and maintain a dollar-weighted average portfolio life (portfolio maturity measured without reference to any maturity shortening provisions of adjustable rate securities by reference to their interest rate reset dates) of 120 days or less
As a government money market fund, the Board of Trustees has determined not to subject the Fund to a liquidity fee on Fund redemptions. Please note that the Board of Trustees has reserved the ability to change this determination with respect to liquidity fees, but only after providing appropriate prior notice to shareholders.
Principal investment risks
Money Market Risk.You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Adviser is not required to reimburse the Fund for losses, and you should not expect that the Adviser will provide financial support to the Fund at any time, including during periods of market stress. Accordingly, if the value of Fund Shares were to fall below $1.00 per share, there is no guarantee that the Adviser or its affiliates would protect the Fund or redeeming shareholders against any loss of principal.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations (potentially even the U.S. Government). The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Interest Rate Risk.Although the Fund seeks to invest only in high-quality, short-term money market instruments, there is a risk that the value of the securities it holds will fall as a result of the changes in interest rates. Rising interest rates could cause the value of the Fund’s investments to decline, and a decline in interest rates is likely to cause the Fund’s yield to decline. During periods of unusually low or negative interest rates, the Fund’s yield may approach or fall below zero. Such low interest rate environments may prevent the Fund from providing a positive yield or could impair the Fund’s ability to maintain the value of your investment at $1.00 per share. Over time, the real value of the Fund’s yield may be eroded by inflation.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield.
Collateral Risk.With respect to collateral received in repurchase transactions or other investments, the Fund may have significant exposure to government agencies not secured by the full faith and credit of the United States. Such exposure, depending on market conditions, could have a negative impact on the Fund, including minimizing the value of any collateral.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s
3 | Janus Henderson Government Money Market Fund

financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.
U.S. Government Securities Risk.Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.

Minimum Investment Requirements
The minimum investment for American Cancer Society Support – Class T Shares is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Shareholders who invest through financial intermediaries with supermarket and/or self-directed brokerage accounts that maintain omnibus accounts and charge asset-based service fees may not be subject to the $2,500 minimum investment requirement noted above.
Purchases, exchanges, and redemptions can generally be made only through institutional channels, such as financial intermediaries and retirement platforms. You should contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund. Requests must be received in good order by the Fund or its agents (financial intermediary or plan sponsor, if applicable) prior to the close of the trading session of the New York Stock Exchange in order to receive that day’s net asset value.

Payments to broker-dealers and other financial intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders through the management fee and the administration fee paid to the Adviser.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses” for the Fund include a class-level administration fee of 0.28% of the average daily net assets of American Cancer Society Support – Class T Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping and registration functions and also to pay for costs such as shareholder servicing and custody.
The Adviser has contractually agreed to waive and/or reimburse the Fund’s “Total Annual Fund Operating Expenses” to the extent such expenses (excluding brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) exceed 0.46% for at least a one-year period through December 31, 2025. The expense limit is described in the “Expense Limitation” section of this Prospectus.
The Adviser may voluntarily waive and/or reimburse fees to the extent necessary to assist the Fund in attempting to maintain a yield of at least 0.00%. Any waivers and reimbursements are voluntary and could change or be terminated at any time at the discretion of the Adviser. There is no guarantee that the Fund will maintain a positive yield.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. In addition, the Fund will provide shareholders with at least 60 days’ notice prior to changing the 80% investment policy. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
This section takes a closer look at investment strategies and general policies that apply to the Fund. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. The Fund is subject to certain specific Securities and Exchange Commission (“SEC”) rule requirements. Among other things, the Fund is limited to investing in U.S. dollar-denominated instruments with a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended) that are determined to present minimal credit risk.
Security Selection
In selecting securities for the Fund’s portfolio, portfolio management focuses on securities that offer liquidity and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.
Demand Features
Demand features give the Fund the right to resell securities at specified periods prior to their maturity dates. Demand features may shorten the life of a variable or floating rate security or preferred stock, enhance the instrument’s credit quality, and provide a source of liquidity. Demand features are often issued by third party financial institutions, generally domestic and foreign banks. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the banks supporting the Fund’s investments. This will result in exposure to risks pertaining to the banking
7 | Janus Investment Fund

industry, including the foreign banking industry. Brokerage firms and insurance companies also provide certain liquidity and credit support.
Liquidity
The Fund has adopted liquidity requirements (measured at the time of purchase) as noted:
Daily liquidity.The Fund will invest at least 25% of its total assets in “daily liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within one business day, and/or amounts receivable and due unconditionally within one business day on pending sales of portfolio securities.
Weekly liquidity.The Fund will invest at least 50% of its assets in “weekly liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within five business days.
The Fund will limit its investments in illiquid securities to 5% or less of its total assets.
Mortgage- and Asset-Backed Securities
The Fund may purchase fixed or variable rate commercial or residential mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees are backed by the full faith and credit of the U.S. Government, which means that the U.S. Government guarantees that the interest and principal will be paid when due. Fannie Mae and Freddie Mac securities, as well as the securities of other government or government-related entities, are not backed by the full faith and credit of the U.S. Government.
Participation Interests
A participation interest gives the Fund a proportionate, undivided interest in underlying debt securities and usually carries a demand feature.
Repurchase Agreements
The Fund may enter into collateralized repurchase agreements by cash or U.S. Government securities. Repurchase agreements are transactions in which the Fund purchases securities and simultaneously commits to resell those securities to the seller at an agreed-upon price on an agreed-upon future date. The repurchase price reflects a market rate of interest.
U.S. Government Securities
The Fund may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer.
Variable and Floating Rate Securities
The Fund may purchase variable and floating rate demand notes of U.S. Government issuers. These securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to an interest rate index or market interest rate. Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness.
Risks of the Fund
The value of your investment may vary over time, and you may lose money by investing in the Fund. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
8 | Janus Investment Fund

Commercial Paper Risk.Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations. The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield. Further, regardless of how well securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions that have a significant effect on issuers. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. In the event the underlying loans are not paid, the securities’ issuer could be forced to sell the assets and recognize losses on such assets, which could impact the Fund’s yield and return. Mortgage- and asset-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. Investments in mortgage- and asset-backed securities are subject to both extension risk, where during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally expected, and prepayment risk, where during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated. These risks may reduce the Fund’s returns. In addition, investments in certain mortgage- and
9 | Janus Investment Fund

asset-backed securities may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities.
Participation Interests Risk.If the Fund purchases a participation interest, it typically will have a contractual relationship with the lender and not with the borrower. The Fund may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender, or any other intermediate participant. The Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender and only upon receipt by the lender of the payments from the borrower. The failure by the Fund to receive scheduled interest or principal payments may adversely affect the income of the Fund and may likely reduce the value of its assets, which would be reflected by a reduction in the Fund’s net asset value.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security. While it is not possible to eliminate all risks from these transactions, it is the policy of the Fund to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory. There is no guarantee that the Adviser’s analysis of the creditworthiness of the counterparty will be accurate, and the underlying collateral involved in the transaction can expose the Fund to additional risk regardless of the creditworthiness of the parties involved in the transaction.
U.S. Government Securities Risk.Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets. Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Board of Trustees (“Trustees”), to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Adviser generally pays the salaries, fees, and expenses of Fund officers with respect to services provided to the Fund, although some expenses related to compensation payable to the Fund’s Chief Compliance Officer and compliance staff are shared with the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs other expenses, including legal and auditing fees and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund pays.
The following table reflects the Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual investment advisory fee rate paid by the Fund to the Adviser (net of fee waivers). The rate shown is a fixed rate based on the Fund’s average daily net assets.

American Cancer Society Support
The Adviser will donate from the Adviser’s own resources, an amount representing 50% of the Adviser’s quarterly management fee revenue attributable to the Fund, net of any fee waivers and/or expense reimbursements, to the American Cancer Society® (“ACS”) in connection with ACS’s agreement to license the use of its name and trademarks to the Adviser. The Adviser will make annual minimum contributions to ACS of $1 million from 2024 to 2027, and in each year thereafter to the extent this arrangement continues. The Adviser’s donation may result in a tax benefit for the Adviser, but will not
11 | Janus Investment Fund

result in a tax benefit for shareholders. The ACS does not endorse any service or product. Shares of the Fund are not sponsored, endorsed, or promoted by the ACS, and the ACS is not an investment adviser or service provider to the Fund, Trust, or Adviser.
A discussion regarding the basis for the Trustees’ approval of the Fund’s investment advisory agreement is included in the Fund’s semiannual report (for the period ended December 31, 2023) and in the Fund’s financial statements (for the period ended June 30, 2024, and moving forward). You can request the Fund’s semiannual reports or financial statements (as they become available), free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary, or by contacting a Janus Henderson representative at 1-877-335-2687. This information is also available, free of charge, at janushenderson.com/info.
Administration fee
The Fund pays an administration fee of 0.28% of the average daily net assets of American Cancer Society Support – Class T Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping, fund accounting, preparation of reports and prospectuses distributed to current shareholders, and registration functions. This administration fee also covers expenses including, but not limited to, custody, transfer agency, shareholder servicing, and provision of office facilities and personnel necessary to carry on the business of the Fund. The administration fee may also be used to pay financial intermediaries for subaccounting, order processing for omnibus or networked accounts, or other shareholder servicing. Order processing includes the submission of transactions by financial intermediaries through the National Securities Clearing Corporation or similar systems, or those processed on a manual basis.
Expense limitation
The Adviser has contractually agreed to waive and/or reimburse operating expenses to the extent that the Fund’s total annual fund operating expenses (excluding brokerage commissions, interest, dividends, taxes, acquired fund fees and expenses, and extraordinary expenses) exceed 0.46% for at least a one-year period through December 31, 2025. This contractual waiver may be terminated or modified only at the discretion of the Board of Trustees. For information about how the expense limit affects the total expenses of the Fund, see the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus.
Portfolio management
Janus Henderson Government Money Market Fund
Effective February 1, 2025, Co-Portfolio Managers Andrew Forman and Garrett Strum will be responsible for the day-to-day management of the Fund. Mr. Strum, as Lead Portfolio Manager, has the authority to exercise final decision-making on the overall portfolios.
Andrew Forman is Co-Portfolio Manager of Janus Henderson Government Money Market Fund, which he has co-managed since February 2025. He is also Portfolio Manager of other Janus Henderson accounts. Mr. Forman joined the Adviser in 2013. He holds a Bachelor of Arts degree in Economics with a minor in Atmospheric and Oceanic Sciences from the University of Colorado.
Garrett Strum is Executive Vice President and Lead Portfolio Manager of Janus Henderson Government Money Market Fund, which he has managed or co-managed since May 2017. He is also Portfolio Manager of other Janus Henderson accounts and performs duties as an analyst. Mr. Strum holds a Bachelor of Science degree in Business with concentrations in Finance and Real Estate from Colorado State University.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed
12 | Janus Investment Fund

by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. To the extent that the Fund is an underlying fund in a Janus Henderson “fund of funds,” a potential conflict of interest arises when allocating the assets of the Janus Henderson “fund of funds” to the Fund. Purchases and redemptions of fund shares by a Janus Henderson “fund of funds” due to reallocations or rebalancings may result in a fund having to sell securities or invest cash when it otherwise would not do so, which could accelerate the recognition of taxable income or cause actual expenses to increase. The impact of these transactions is likely to be greater when a Janus Henderson “fund of funds” purchases, redeems, or owns a substantial portion of the Fund’s shares. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.

Other information
CLOSED FUND POLICIES
The Fund may limit sales of its Shares to new investors. If sales of the Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Fund
The Fund is distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Dividends representing substantially all of the net investment income and any net realized gains on sales of securities are declared daily (Saturdays, Sundays, and holidays included) and distributed as of the last business day of each month. If a month begins on a Saturday, Sunday, or holiday, dividends for those days are declared and distributed at the end of the preceding month.
Purchase orders received prior to 4:00 p.m. (New York time) on a bank business day (a day when both the New York Stock Exchange (“NYSE”) and the Federal Reserve Banks are open) will begin to accrue dividends on the following bank business day.
Redemption requests received prior to 4:00 p.m. (New York time) on a bank business day will receive that day’s dividends. Proceeds of such redemption will normally be sent on the next bank business day.
The Fund reserves the right to require purchase and redemption requests and payments prior to these times on days when the bond markets or NYSE close early. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early).
For your convenience, distributions of dividends and capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact your financial intermediary. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”).
15 | Janus Investment Fund

Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary will report cost basis information to you and to the IRS. Your intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s guide
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.
American Cancer Society Support – Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, the Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms.
Pricing of fund shares
The per share net asset value (“NAV”) for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the NYSE (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early). The value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
All purchases and redemptions will be duly processed at the NAV next calculated after your request is received in good order by the Fund or its agents. In order to receive a day’s price, your order must be received in good order by the Fund or its agents by the close of the trading session of the NYSE. The Fund reserves the right to require purchase and/or redemption requests from a financial intermediary or plan sponsor prior to this time on days when the bond markets or the NYSE close early. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares.
The Fund’s portfolio securities are valued at amortized cost, which approximates market value. Amortized cost valuation involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity (or such other date as permitted by Rule 2a-7) of any discount or premium. If fluctuating interest rates cause the market value of the Fund’s portfolio to deviate more than 1/2 of 1% from the value determined on the basis of amortized cost, the Trustees will consider whether any action, such as adjusting the NAV to reflect current market conditions, should be initiated to prevent any material dilutive effect on shareholders.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Fund under the arrangements made between your financial intermediary or plan sponsor and its customers. The Fund is not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not currently offered by the Fund, the Adviser or its affiliates pay fees, from their own assets, to selected brokerage firms or other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries.
For American Cancer Society Support – Class T Shares, the Adviser, the Distributor, or their affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to
17 | Janus Investment Fund

any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. The Adviser or its affiliates may have numerous agreements to make payments to financial institutions which perform recordkeeping or other administrative services with respect to shareholder accounts.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
Purchases of Shares may be made only through financial intermediaries. Contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund, including additional information on minimum initial or subsequent investment requirements. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Fund’s behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of shareholders for the Fund or that provide services in connection with investments in the Fund. You should consider such arrangements when evaluating any recommendation of the Fund.
The Fund reserves the right to require purchase requests and payments from the financial intermediary or plan sponsor prior to 4:00 p.m. (New York time) on days when the bond markets or NYSE close early. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early).
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading.
18 | Janus Investment Fund

In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Minimum Investment Requirements
The minimum investment for American Cancer Society Support – Class T Shares is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. Accounts held through wrap programs may not be subject to these minimums. In addition, shareholders who invest through financial intermediaries with supermarket and/or self-directed brokerage accounts that maintain omnibus accounts and charge asset-based service fees may not be subject to the $2,500 minimum investment requirement noted above. Investors should refer to their intermediary for additional information.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
The Fund reserves the right to change the amount of these minimums from time to time or to waive them in whole or in part.
Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Exchanges
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Contact your financial intermediary or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan. Only accounts beneficially owned by natural persons will be allowed to exchange to Janus Henderson Money Market Fund.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received.
19 | Janus Investment Fund

The Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
You must meet the minimum investment amount for the fund.
The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Redemptions
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
Redemptions, like purchases, may generally be effected only through financial intermediaries. Please contact your financial intermediary or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of the Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by the Fund or its agents. The Fund reserves the right to require redemption requests prior to 4:00 p.m. (New York time) on days when the bond markets or NYSE close early. The Fund reserves the right to close in conjunction with the closure of the bond markets (i.e., when the bond markets are closed or close early). Redemption proceeds will normally be sent within two business days following receipt of the redemption order. The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may
20 | Janus Investment Fund

potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Suspension of Redemptions
In the event the Fund’s market-based net asset value per share has deviated from the Fund’s amortized cost price per share, or the Fund’s Trustees, including a majority of Independent Trustees, determines that such a deviation is likely to occur, then the Trustees will take such action as they deem appropriate including, but not limited to, suspending redemptions and the payment of redemption proceeds, in order to facilitate the liquidation of the Fund. In addition, if the Fund’s weekly liquid assets fall below 10%, the Fund may cease honoring redemptions and liquidate at the discretion of the Trustees. Prior to suspending redemptions, the Fund would be required to notify the SEC of its decision to suspend redemptions and liquidate. If the Fund ceases honoring redemptions and makes a decision to liquidate, the Fund expects that it would notify shareholders on the Fund’s websites or by press release.
Systematic Withdrawal Plan
You may arrange for periodic redemptions by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.The Fund is required to disclose its complete holdings in the annual and semiannual financial statements located in Form N-CSR. In addition, the Fund is required to disclose its complete holdings in a monthly report on Form N-MFP within 5 business days after each month end. Form N-CSR filings and Form N-MFP reports (i) are available on the SEC’s website at http://www.sec.gov and (ii) are available without charge, upon request, by calling a Janus Henderson representative at 1-877-335-2687 (toll free). Holdings are generally posted within 5 business days after each month end under Full Holdings for the Fund at janushenderson.com/info.

Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor is responsible for providing annual and semiannual reports of the Fund. Please contact your financial intermediary or plan sponsor to obtain these reports. The Fund’s fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Agency discount notes are U.S. Government securities that are issued by a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. The Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Other Investments, Strategies, and/or Techniques
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Principal investment strategies
The Fund pursues its investment objectives by investing primarily in high quality debt obligations and obligations of financial institutions. Debt obligations may include commercial paper, notes, and bonds. Obligations of financial institutions include certificates of deposit and time deposits. The Fund also intends to invest in repurchase agreements including those secured by U.S. Government agencies. Some government agencies backed by the full faith and credit of the United States are supported by the issuer’s ability to borrow from the U.S. Treasury, some are supported only by the credit of the issuer, and some are supported by the United States in some other way.
The Fund will:
invest in high-quality, short-term money market instruments that present minimal credit risks, as determined by the Adviser
invest only in U.S. dollar-denominated instruments that have a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended)
maintain a dollar-weighted average portfolio maturity of 60 days or less and maintain a dollar-weighted average portfolio life (portfolio maturity measured without reference to any maturity shortening provisions of adjustable rate securities by reference to their interest rate reset dates) of 120 days or less
Principal investment risks
Money Market Risk.You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your Shares. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Adviser is not required to reimburse the Fund for losses, and you should not expect
2 | Janus Henderson Money Market Fund

that the Adviser will provide financial support to the Fund at any time, including during periods of market stress. Accordingly, if the value of Fund Shares were to fall below $1.00 per share, there is no guarantee that the Adviser or its affiliates would protect the Fund or redeeming shareholders against any loss of principal.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations. The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Interest Rate Risk.Although the Fund seeks to invest only in high-quality, short-term money market instruments, there is a risk that the value of the securities it holds will fall as a result of the changes in interest rates. Rising interest rates could cause the value of the Fund’s investments to decline, and a decline in interest rates is likely to cause the Fund’s yield to decline. During periods of unusually low or negative interest rates, the Fund’s yield may approach or fall below zero. Such low interest rate environments may prevent the Fund from providing a positive yield or could impair the Fund’s ability to maintain the value of your investment at $1.00 per share. Over time, the real value of the Fund’s yield may be eroded by inflation.
Retail Money Market Fund Risk.The Fund is classified as a “retail money market fund,” as such term is defined in or interpreted under the rules governing money market funds. A retail money market fund is a money market fund that has policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. The Fund may impose a discretionary liquidity fee of up to 2% on Fund redemptions if the Fund’s Board of Trustees, or its delegate, determines that a liquidity fee is in the best interests of the Fund. The Board of Trustees has delegated liquidity fee determinations to the Adviser, subject to Board guidelines and oversight.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield.
Collateral Risk.With respect to collateral received in repurchase transactions or other investments, the Fund may have significant exposure to financial services, mortgage markets, and government agencies not secured by the full faith and credit of the United States. Such exposure, depending on market conditions, could have a negative impact on the Fund, including minimizing the value of any collateral.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
3 | Janus Henderson Money Market Fund

Commercial Paper Risk.Commercial paper is a debt obligation usually issued by corporations in order to finance their current operations. Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.
U.S. Government Securities Risk.Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class D Shares of the Fund commenced operations on February 16, 2010, as a result of the restructuring of Class J Shares, the predecessor share class. The performance shown for Class D Shares for periods prior to February 16, 2010, reflects the performance of the Fund’s former Class J Shares, calculated using the fees and expenses in effect during the periods shown, net of any applicable fee and expense limitations or waivers. If Class D Shares of the Fund had been available during periods prior to February 16, 2010, the performance shown may have been different. The performance shown for the periods following the Fund’s commencement of Class D Shares reflects the fees and expenses of Class D Shares, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table shows how the Fund’s returns over different periods average out. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/allfunds or by calling 1-800-525-3713.

Payments to broker-dealers and other financial intermediaries
With respect to share classes not offered in this Prospectus, the Fund or its distributor (or its affiliates) pay select broker-dealer firms or other financial intermediaries for the sale of Fund shares and related services.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders through the management fee and the administration fee paid to the Adviser.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses” for the Fund include a class-level administration fee of 0.18% of the average daily net assets of Class D Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping and registration functions and also to pay for costs such as shareholder servicing and custody.
The Adviser may voluntarily waive and/or reimburse fees to the extent necessary to assist the Fund in attempting to maintain a yield of at least 0.00%. Any waivers and reimbursements are voluntary and could change or be terminated at any time at the discretion of the Adviser. There is no guarantee that the Fund will maintain a positive yield.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
This section takes a closer look at investment strategies and general policies that apply to the Fund. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. The Fund is subject to certain specific Securities and Exchange Commission (“SEC”) rule requirements. Among other things, the Fund is limited to investing in U.S. dollar-denominated instruments with a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended) that are determined to present minimal credit risk.
Security Selection
In selecting securities for the Fund’s portfolio, portfolio management focuses on securities that offer liquidity and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.
Debt Obligations
The Fund may invest in U.S. dollar-denominated debt obligations. Debt obligations include:
commercial paper
notes and bonds
variable amount master demand notes (the payment obligations on these instruments may be backed by securities, swap agreements or other assets, by a guarantee of a third party, or solely by the unsecured promise of the issuer to make payments when due)
privately issued commercial paper or other securities that are restricted as to disposition under the federal securities laws
6 | Janus Investment Fund

Demand Features
Demand features give the Fund the right to resell securities at specified periods prior to their maturity dates. Demand features may shorten the life of a variable or floating rate security or preferred stock, enhance the instrument’s credit quality, and provide a source of liquidity. Demand features are often issued by third party financial institutions, generally domestic and foreign banks. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the banks supporting the Fund’s investments. This will result in exposure to risks pertaining to the banking industry, including the foreign banking industry. Brokerage firms and insurance companies also provide certain liquidity and credit support.
Liquidity
The Fund has adopted liquidity requirements (measured at the time of purchase) as noted:
Daily liquidity.The Fund will invest at least 25% of its total assets in “daily liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within one business day, and/or amounts receivable and due unconditionally within one business day on pending sales of portfolio securities.
Weekly liquidity.The Fund will invest at least 50% of its assets in “weekly liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within five business days.
The Fund will limit its investments in illiquid securities to 5% or less of its total assets.
Mortgage- and Asset-Backed Securities
The Fund may purchase fixed or variable rate commercial or residential mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees are backed by the full faith and credit of the U.S. Government, which means that the U.S. Government guarantees that the interest and principal will be paid when due. Fannie Mae and Freddie Mac securities, as well as the securities of other government or government-related entities, are not backed by the full faith and credit of the U.S. Government.
The Fund may also purchase mortgage- and asset-backed securities through single- and multi-seller conduits, collateralized debt obligations, structured investment vehicles, and other similar securities. Asset-backed securities may be backed by various consumer obligations, including automobile loans, equipment leases, credit card receivables, or other collateral.
Obligations of Financial Institutions
The Fund may invest in obligations of financial institutions. Examples of obligations of financial institutions include:
negotiable certificates of deposit, bankers’ acceptances, time deposits, and other obligations of U.S. banks (including savings and loan associations) having total assets in excess of one billion dollars and U.S. branches of foreign banks having total assets in excess of ten billion dollars
Eurodollar and Yankee bank obligations (Eurodollar bank obligations are dollar-denominated certificates of deposit or time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee bank obligations are dollar-denominated obligations issued in the U.S. capital markets by foreign banks.)
other U.S. dollar-denominated obligations of foreign banks having total assets in excess of ten billion dollars that the Adviser believes are of an investment quality comparable to obligations of U.S. banks in which the Fund may invest
The Fund may focus its investments in the financial services sector.
Participation Interests
A participation interest gives the Fund a proportionate, undivided interest in underlying debt securities and usually carries a demand feature.

Repurchase Agreements
The Fund may enter into collateralized repurchase agreements by cash or U.S. Government securities. Repurchase agreements are transactions in which the Fund purchases securities and simultaneously commits to resell those securities to the seller at an agreed-upon price on an agreed-upon future date. The repurchase price reflects a market rate of interest.
U.S. Government Securities
The Fund may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer.
Variable and Floating Rate Securities
The Fund may invest in securities which have variable or floating rates of interest. These securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to an interest rate index or market interest rate. Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness.
Risks of the Fund
The value of your investment may vary over time, and you may lose money by investing in the Fund. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
Commercial Paper Risk.Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations. The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Currency Risk.To the extent the Fund holds a U.S. dollar-denominated foreign security, its value may be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Financial Services Sector Risk.To the extent the Fund focuses its investments on issuers in the financial services sector, the Fund will have more exposure to the risks inherent to the financial services sector. Financial services companies may be adversely affected by changes in regulatory framework or interest rates that may negatively affect financial services businesses; exposure of a financial institution to a nondiversified or concentrated loan portfolio; exposure to financial leverage and/or
8 | Janus Investment Fund

investments or agreements that, under certain circumstances, may lead to losses; and the risk that a market shock or other unexpected market, economic, political, regulatory, or other event, including a banking crisis or financial emergency, might lead to a sudden decline in the values of most or all financial services companies. In addition, a decline in the credit quality of an issuer, the provider of credit support, may also have a negative effect on the Fund.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield. Further, regardless of how well securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions that have a significant effect on issuers. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. In the event the underlying loans are not paid, the securities’ issuer could be forced to sell the assets and recognize losses on such assets, which could impact the Fund’s yield and return. Mortgage- and asset-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. Investments in mortgage- and asset-backed securities are subject to both extension risk, where during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally expected, and prepayment risk, where during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated. These risks may reduce the Fund’s returns. In addition, investments in certain mortgage- and asset-backed securities may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities.
Participation Interests Risk.If the Fund purchases a participation interest, it typically will have a contractual relationship with the lender and not with the borrower. The Fund may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender, or any other intermediate participant. The Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender and only upon receipt by the lender of the payments from the borrower. The failure by the Fund to receive scheduled interest or principal payments may adversely affect the income of the Fund and may likely reduce the value of its assets, which would be reflected by a reduction in the Fund’s net asset value.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security. While it is not possible to eliminate all risks from these transactions, it is the policy of the Fund to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory. There is no guarantee that the Adviser’s analysis of the creditworthiness of the counterparty will be accurate, and
9 | Janus Investment Fund

the underlying collateral involved in the transaction can expose the Fund to additional risk regardless of the creditworthiness of the parties involved in the transaction.
Sovereign Debt Risk.Foreign, Eurodollar, and, to a limited extent, Yankee bank obligations are subject to certain sovereign debt risks. One such risk is the possibility that a foreign government might prevent dollar-denominated funds from flowing across its borders. Other risks include: adverse political and economic developments in a foreign country, the extent and quality of government regulation of financial markets and institutions, the imposition of foreign withholding taxes, and expropriation or nationalization of foreign issuers.
U.S. Government Securities Risk.Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets. Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Board of Trustees (“Trustees”), to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Adviser generally pays the salaries, fees, and expenses of Fund officers with respect to services provided to the Fund, although some expenses related to compensation payable to the Fund’s Chief Compliance Officer and compliance staff are shared with the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs other expenses, including legal and auditing fees and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund pays.
The following table reflects the Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual investment advisory fee rate paid by the Fund to the Adviser (net of fee waivers). The rate shown is a fixed rate based on the Fund’s average daily net assets.

You can request the Fund’s semiannual reports or financial statements (as they become available), free of charge, by contacting a Janus Henderson representative at 1-800-525-3713.

Administration fee
The Fund pays an administration fee of 0.18% of the average daily net assets of Class D Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping, fund accounting, preparation of reports and prospectuses distributed to current shareholders, and registration functions. This administration fee also covers expenses including, but not limited to, custody, transfer agency, shareholder servicing, and provision of office facilities and personnel necessary to carry on the business of the Fund.
Portfolio management
Janus Henderson Money Market Fund
Effective February 1, 2025, Co-Portfolio Managers Andrew Forman and Garrett Strum will be responsible for the day-to-day management of the Fund. Mr. Strum, as Lead Portfolio Manager, has the authority to exercise final decision-making on the overall portfolios.
Andrew Forman is Co-Portfolio Manager of Janus Henderson Money Market Fund, which he has co-managed since February 2025. He is also Portfolio Manager of other Janus Henderson accounts. Mr. Forman joined the Adviser in 2013. He holds a Bachelor of Arts degree in Economics with a minor in Atmospheric and Oceanic Sciences from the University of Colorado.
Garrett Strum is Executive Vice President and Lead Portfolio Manager of Janus Henderson Money Market Fund, which he has managed or co-managed since May 2017. He is also Portfolio Manager of other Janus Henderson accounts and performs duties as an analyst. Mr. Strum holds a Bachelor of Science degree in Business with concentrations in Finance and Real Estate from Colorado State University.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.

Other information
CLOSED FUND POLICIES
The Fund may limit sales of its Shares to new investors. If sales of the Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
Investments in the Fund are limited to accounts beneficially owned by natural persons. In order to make an initial investment in the Fund, investors may be required to provide certain information (e.g., Social Security number or government-issued identification) to demonstrate eligibility to invest in the Fund. The Fund reserves the right to involuntarily redeem Fund Shares in any account that are not beneficially owned by natural persons, after providing notice.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Fund
The Fund is distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Dividends representing substantially all of the net investment income and any net realized gains on sales of securities are declared daily (Saturdays, Sundays, and holidays included) and distributed as of the last business day of each month. If a month begins on a Saturday, Sunday, or holiday, dividends for those days are declared and distributed at the end of the preceding month.
Purchase orders received prior to 4:00 p.m. (New York time) on a bank business day (a day when both the New York Stock Exchange (“NYSE”) and the Federal Reserve Banks are open) will begin to accrue dividends on the following bank business day.
Redemption requests received prior to 4:00 p.m. (New York time) on a bank business day will receive that day’s dividends. Proceeds of such redemption will normally be sent on the next bank business day.
The Fund reserves the right to require purchase and redemption requests and payments prior to these times on days when the bond markets or NYSE close early.
For your convenience, distributions of dividends and capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact a Janus Henderson representative at 1-800-525-3713. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
Distribution Options
When you open an account, it will automatically provide for reinvestment of all distributions. If you have a non-retirement account, you may change your distribution option at any time by logging on to janushenderson.com/individual, by calling a Janus Henderson representative, or by writing to the Fund at one of the addresses listed in the Shareholder’s Manual section of this Prospectus. The Fund offer the following options:
Reinvestment Option.You may reinvest your income dividends and capital gains distributions in additional shares.
Cash Option.You may receive your income dividends and capital gains distributions in cash.
Redirect Option.You may direct your dividends to purchase shares of another Janus Henderson fund.
The Fund reserves the right to reinvest uncashed dividend and distribution checks into your open non-retirement account at the NAV next computed after the check is cancelled. Subsequent distributions may also be reinvested. For more information, refer to “Shareholder Services and Account Policies.”
TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain
14 | Janus Investment Fund

(i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”).
Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, the Janus Henderson funds will report cost basis information to you and to the IRS. The Fund will permit shareholders to elect their preferred cost basis method. In the absence of an election, the Fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
A liquidity fee imposed by the Fund will reduce the amount you will receive upon the redemption of your Shares, and will decrease the amount of any capital gain or increase the amount of any capital loss you will recognize as a result of such redemption. There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by money market funds, and such tax treatment may be the subject of future guidance issued by the IRS. If the Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under
15 | Janus Investment Fund

Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s manual
This Shareholder’s Manual is for those shareholders investing directly with the Fund. This section will help you become familiar with the different types of accounts you can establish with the Adviser. It also explains in detail the wide array of services and features you can establish on your account, as well as describes account policies and fees that may apply to your account. Account policies (including fees), services, and features may be modified or discontinued without shareholder approval or prior notice.
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.
Investments in the Fund are limited to accounts beneficially owned by natural persons. In order to make an initial investment in the Fund, the Fund requires that a shareholder provide certain information (e.g., Social Security number, permanent street address, date of birth, or government-issued identification) that confirms your eligibility to invest in the Fund. Accounts that are not beneficially owned by natural persons, such as business and limited liability company accounts, charitable or financial organizations, and corporate and S-Corp accounts, are not eligible to invest in the Fund, and will be involuntarily redeemed from the Fund after having been provided sufficient notice.
Doing business with Janus Henderson
The Fund offers multiple classes of shares in order to meet the needs of various types of investors. You should carefully consider which class of shares to purchase.

Participants in certain retirement plans, including but not limited to, Janus Henderson prototype Money Purchase Pension and Profit Sharing plans, SEP IRAs, SARSEP IRAs, or outside qualified retirement plans, may not be subject to the stated minimums.

**
All states have repealed UGMA statutes, enacting UTMA statutes in their place. Existing UGMA accounts established before the date of repeal are grandfathered using the original UGMA age of termination.
Minimum Investment Requirements
Due to the proportionately higher costs of maintaining small accounts, the Fund reserves the right to deduct an annual $25 minimum balance fee per Fund account (paid to the Transfer Agent) with values below the minimums described under “Minimum Investments” or to close Fund accounts valued at less than $100. This policy may not apply to accounts that fall below the minimums solely as a result of market value fluctuations or to those accounts not subject to a minimum investment requirement. The fee or account closure will occur during the fourth quarter of each calendar year. You will receive written notice before we charge the $25 fee or close your account so that you may increase your account balance to the required minimum provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of the fee being charged or the redemption.
Available Incentive Programs
Bonus Program for Taxable Account Purchases and Tax-Advantaged Account Transfers/Rollovers
Through the Transfer Agent’s Bonus Program, the Transfer Agent will pay a bonus of up to $2,500 to you for making certain eligible purchases of Fund shares in taxable accounts or transfers/rollovers from a non-Janus Henderson fund account into a Janus Henderson fund tax-advantaged account. The Bonus Program is valid with an eligible purchase or transfer/rollover of $20,000 or more. If you meet the eligibility requirements for the Bonus Program and enroll in it, the Transfer Agent will deposit a bonus payment into your Fund account within approximately 30 days after the deposit of eligible funds in good order and receipt of a signed contract governing the Bonus Program. An investor must keep the eligible purchase in the account for a period of 360 calendar days in order to retain the bonus payment. Any sale of the qualifying purchase amount (in whole or in part), transfer, or closure of the account within the 360 calendar day period may result in forfeiture of the bonus payment. Any decline in an account’s value due solely to market value fluctuations will not result in the forfeiture of the bonus payment. Only taxable account purchases or transfers/rollovers to tax-advantaged accounts that are made on or after January 1, 2024 through December 31, 2024 are eligible for a bonus payment. The eligible period for the Bonus Program may be extended beyond this time frame at the sole discretion of the Transfer Agent. Before enrolling in the Bonus Program, consult with your tax advisor about the appropriate tax treatment for the bonus offer and any tax implications associated with the receipt of a bonus payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke this Bonus Program at any time without advance notice.
You can request more information about the Transfer Agent’s Bonus Program and eligibility requirements for taxable accounts by contacting a Janus Henderson representative at 1-800-525-3713 or by visiting www.janushenderson.com/bonus. You can request more information about the Bonus Program for tax-advantaged account transfers/rollovers by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Contribution Match Payments
Investors that transfer/rollover assets from a non-Janus Henderson fund account into a tax-advantaged account are also eligible for the Transfer Agent’s Contribution Match Program. To receive a Transfer Agent’s Contribution Match payment, (i) the value of your tax-advantaged account must remain equal to or greater than the value of the eligible transfer/rollover (but not including any losses due solely to market value fluctuations) for 12 months following the receipt of your transfer/rollover in good order and receipt of a signed contract governing the Contribution Match Program, and (ii) you must provide instructions to the Transfer Agent on how to invest these payments. The Transfer Agent’s Contribution Match payments will
18 | Janus Investment Fund

commence at the end of the first quarter in 2025 following an eligible contribution during the first quarter of 2025 into a Janus Henderson fund tax-advantaged account. The eligible period for the Transfer Agent’s Contribution Match payments may be extended beyond this time frame at the sole discretion of the Transfer Agent. The Transfer Agent will match a percentage of these contributions based on the aggregate value of eligible 2024 rollover or asset transfer amounts, and provide a matching contribution in an amount up to ten percent of your contribution. Before enrolling in the Contribution Match Program, consult with your tax advisor about the appropriate tax treatment for the Transfer Agent’s Contribution Match payments and any tax implications associated with the receipt of a Contribution Match payment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Contribution Match Program at any time without advance notice.
You can request more information about the Contribution Match Program and eligibility requirements by contacting a Janus Henderson Direct Rollover Specialist at 1-800-379-7603 or by visiting www.janushenderson.com/bonus.
Ready. Invest. Go. Program
New investors creating a new Janus Henderson direct account are eligible to participate in the Transfer Agent’s Ready. Invest. Go. Program. After the new investor has completed the required Ready. Invest. Go. Program Contract, the Transfer Agent will fund the $100 initial investment required for new investors, provided that new investors enroll in Janus Henderson’s automatic investment program in an amount equal to at least $50 per month. New investors will forfeit the $100 bonus contributed by the Transfer Agent if their account is closed or if their automatic monthly investment program payment is terminated within two years from the date the initial investment was made. Investor-initiated amounts outside of the initial investment are redeemable at any time at net asset value. Before enrolling in the Ready. Invest. Go. Program, new investors should consult with their tax advisor about the appropriate tax treatment for participating in the Ready. Invest. Go. Program and any tax implications associated with the receipt of the $100 initial investment. The Transfer Agent reserves the right to change the terms, restrict, or revoke the Ready. Invest. Go. Program at any time without advance notice.
You can request more information about the Transfer Agent’s Ready. Invest. Go. Program by contacting a Janus Henderson representative at 1-800-525-3713.

Profit Sharing or Money Purchase Pension Plans
These plans are open to corporations, partnerships, and small business owners (including sole proprietors) for the benefit of their employees and themselves. You may only maintain this type of account via written request. Please contact a Janus Henderson representative for more information.

Pricing of fund shares
The per share net asset value (“NAV”) for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the NYSE (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. The value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
All purchases, exchanges, and redemptions will be duly processed at the NAV as described under “Policies in Relation to Transactions” after a request is received in good order by the Fund or its agents.
The Fund’s portfolio securities are valued at amortized cost, which approximates market value. Amortized cost valuation involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity (or such other date as permitted by Rule 2a-7) of any discount or premium. If fluctuating interest rates cause the market value of the Fund’s portfolio to deviate more than 1/2 of 1% from the value determined on the basis of amortized cost, the Trustees will consider whether any action, such as adjusting the NAV to reflect current market conditions, should be initiated to prevent any material dilutive effect on shareholders.
Policies in Relation to Transactions
All requests, including but not limited to, exchanges between the Fund and other Janus Henderson funds, purchases by check or automated investment, redemptions by wire transfer, ACH transfer, or check, must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE (normally 4:00 p.m. New York time) in order to receive that day’s NAV. Transaction requests submitted in writing and mailed to Janus Henderson’s P.O. Box, once delivered, are considered received for processing the following business day. Transactions involving funds which pay dividends will generally begin to earn dividends, as applicable, on the first bank business day following the date of purchase. The Fund reserves the right to require purchase and/or redemption requests prior to this time on days when the bond markets or the NYSE close early. Please call a Janus Henderson representative for details.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary and when considering which share class of a fund is most appropriate.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions,
22 | Janus Investment Fund

access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you.
Paying for shares
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to buy shares.
Please note the following when purchasing Shares:
Cash, credit cards, third party checks (with certain limited exceptions), travelers cheques, credit card checks, line of credit checks, or money orders will not be accepted.
All purchases must be made in U.S. dollars and checks must be drawn on U.S. banks or an accepted non-U.S. bank.
Purchases initiated using a bill-pay service (or an equivalent) and presented either electronically or in the form of a check are considered direct deposit transactions.
When purchasing Shares through the Automatic Investment Program, your automatic investment selection(s) will generally be active within three days following receipt of your authorization for the date and amount you specify. If no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. If the balance in the Janus Henderson fund account you are buying into falls to zero as the result of a redemption, exchange, or minimum balance fee, your Automatic Investment Program will be discontinued.
We may make additional attempts to debit your predesignated bank account for automated investments that initially fail. You are liable for any costs associated with these additional attempts. If your automated investment fails, you may purchase Shares of the Fund by submitting good funds via another method accepted by the Fund (e.g., by wire transfer). In this case, your purchase will be processed at the next NAV determined after we receive good funds, not at the NAV available as of the date of the original request.
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading.
If all or a portion of a purchase is received for investment without a specific fund designation, for investment in one of our closed funds, or for investment in a fund that is not yet available for public sale, the undesignated amount or entire investment, as
23 | Janus Investment Fund

applicable, will be invested in Janus Henderson Government Money Market Fund. For investments without a specific fund designation, where you own a single Fund account with a current balance greater than zero, the investment will be applied to that Fund account. For investments without a specific fund designation, where you own two or more Fund accounts with current balances greater than zero, and for investments in closed funds, unless you later direct Janus Henderson to (i) buy shares of another Janus Henderson fund or (ii) sell shares of Janus Henderson Government Money Market Fund and return the proceeds (including any dividends earned) to you, Janus Henderson will treat your inaction as approval of the purchase of Janus Henderson Government Money Market Fund. If you hold shares of a closed fund and submit an order directly to Janus Henderson for your account in that closed fund, your account must be open and your order must clearly indicate that you are currently a shareholder of the closed fund, or your money will be invested in Janus Henderson Government Money Market Fund. If you submit an order to buy shares of a fund that is not yet available for investment (during a subscription period), your investment will be held in Janus Henderson Government Money Market Fund until the new fund’s commencement of operations. At that time, your investment (including any dividends) will be automatically exchanged from Janus Henderson Government Money Market Fund to the new fund. All orders for purchase, exchange, or redemption will receive the NAV as described under “Policies in Relation to Transactions.”
For Fund purchases by check, if your check does not clear for any reason, your purchase will be cancelled.
If your purchase is cancelled for any reason, you will be responsible for any losses or fees imposed by your bank and any losses incurred by the Fund as a result. The Fund may redeem shares held in your account to cover any losses it incurs if your purchase is cancelled.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), the Adviser is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, the Adviser may temporarily limit additional share purchases. In addition, the Adviser may close an account if it is unable to verify a shareholder’s identity. Please contact a Janus Henderson representative if you need additional assistance when completing your application or additional information about the Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
The Fund has also adopted an identity theft policy (“Red Flag Policy”) to detect, prevent, and mitigate patterns, practices, or specific activities that indicate the possible existence of identity theft. The Fund is required by law to obtain certain personal information which will be used to verify your identity. The Red Flag Policy applies to the opening of Fund accounts and activity with respect to existing accounts.
Exchanges
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
Please note the following when exchanging Shares:
An exchange represents the redemption (or sale) of shares from the Fund and the purchase of shares of another fund, which may produce a taxable gain or loss in a non-retirement account.
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. The Fund’s fees and expenses differ between share classes. Exchanging from a direct share class to one held through an intermediary typically results in increased expenses. This is because share classes distributed through intermediaries include additional fees for administration and/or distribution to pay
24 | Janus Investment Fund

for services provided by intermediaries. Please read the Prospectus for the share class you are interested in prior to investing in that share class.
New regular Janus Henderson fund accounts established by exchange must be opened with $2,500 or the total account value if the value of the Janus Henderson fund account you are exchanging from is less than $2,500 ($100 for new regular Fund accounts with an automatic investment program of $50 per month). (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
UGMA/UTMA accounts, Traditional or Roth IRAs, Simplified Employee Pension IRAs, and Coverdell Education Savings Accounts established by exchange must meet the minimum investment requirements previously described. If the value of the Janus Henderson fund account you are exchanging from is less than the stated minimum, you must exchange the entire balance. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
New Janus Henderson fund non-retirement accounts established by an exchange (or exchange purchases to an existing Roth IRA) resulting from a required minimum distribution from a retirement account do not have an initial minimum investment requirement. (If your Janus Henderson fund account balance does not meet the minimum investment requirements, you may be subject to an annual minimum balance fee or account closure. For more information, refer to “Minimum Investment Requirements.”)
Exchanges between existing Janus Henderson fund accounts must meet the $50 subsequent investment requirement.
For Systematic Exchanges, if no date is specified on your request, systematic exchanges will be made on the 20th of each month. You may establish this option for as little as $100 per exchange. If the balance in the Janus Henderson fund account you are exchanging from falls below the Systematic Exchange amount, all remaining shares will be exchanged and your Systematic Exchange Program will be discontinued.
The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
With certain exceptions, exchanges between Janus Henderson fund accounts will be accepted only if the registrations are identical. If you are exchanging into a closed Janus Henderson fund, you will need to meet criteria for investing in the closed fund. For more information, refer to Closed Fund Policies in the “Other Information” section of this Prospectus.

Payment of redemption proceeds
As previously noted, with certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
By Electronic Transfer – Generally all accounts are automatically eligible for the electronic redemption option if bank information is provided.
Next Day Wire Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on the next bank business day after receipt of your redemption request (wire transfer). You may be charged a fee for each wire transfer, and your bank may charge an additional fee to receive the wire.
ACH (Automated Clearing House) Transfer – Your redemption proceeds can be electronically transferred to your predesignated bank account on or about the next bank business day after receipt of your redemption request. There is no fee associated with this type of electronic transfer.
25 | Janus Investment Fund

By Check – Redemption proceeds will be sent to the shareholder(s) of record at the address of record normally within seven days after receipt of a valid redemption request. During the 10 days following an address change, requests for redemption checks to be sent to a new address require a signature guarantee.
By Systematic Redemption – If no date is specified on your request, systematic redemptions will be made on or about the 24th of each month. If the balance in the Janus Henderson fund account you are selling from falls to zero, your Systematic Redemption Program will be discontinued.
The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
Generally, orders to sell Shares may be initiated at any time at janushenderson.com/individual, by telephone, or in writing. Certain accounts may require a written request. If the Shares being sold were purchased by check or automated investment, the Fund can delay the payment of your redemption proceeds for up to 15 days from the day of purchase to allow the purchase to clear. In addition, there may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer and your bank information is new. Unless you provide alternate instructions, your proceeds will be invested in Shares of Janus Henderson Government Money Market Fund during the 15-day hold period.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. A temporary hold may also be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult has occurred, is occurring, has been attempted, or will be attempted, as described under “Temporary Suspension of Services.”
Note: For the fastest and easiest way to redeem shares, log on to janushenderson.com/individual* 24 hours a day, 7 days a week.

Large Shareholder Redemptions
Certain large shareholders, such as other funds, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the
26 | Janus Investment Fund

redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Suspension of Redemptions
In the event the Fund’s market-based net asset value per share has deviated from the Fund’s amortized cost price per share, or the Fund’s Trustees, including a majority of Independent Trustees, determines that such a deviation is likely to occur, then the Trustees will take such action as they deem appropriate including, but not limited to, suspending redemptions and the payment of redemption proceeds, in order to facilitate the liquidation of the Fund. In addition, if the Fund’s weekly liquid assets fall below 10%, the Fund may cease honoring redemptions and liquidate at the discretion of the Trustees. Prior to suspending redemptions, the Fund would be required to notify the SEC of its decision to suspend redemptions and liquidate. If the Fund ceases honoring redemptions and makes a decision to liquidate, the Fund expects that it would notify shareholders on the Fund’s websites or by press release.
Information on liquidity fees
Pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended, the Fund may impose a discretionary liquidity fee (not to exceed 2% of the value of the Shares redeemed) on redemptions from the Fund. The Trustees have determined to delegate responsibility for administering any discretionary liquidity fee to the Adviser, subject to Board guidelines and oversight.
Liquidity fees are most likely to be imposed during times of extraordinary market stress. Additionally, the Fund will typically notify financial intermediaries and shareholders if a liquidity fee will be imposed (generally, as of the beginning of the next business day following the announcement that the Fund will impose a liquidity fee).
Liquidity fees payable by shareholders of the Fund may be used to offset any losses realized by the Fund when seeking to honor redemption requests during times of extraordinary market stress.
Liquidity fees would reduce the amount you receive upon redemption of your Shares. The Fund retains the liquidity fees for the benefit of remaining shareholders. The imposition of liquidity fees may also affect the check writing privileges for shareholders of the Fund, as discussed below.
For more information on liquidity fees, please see “Liquidity Fees” in the SAI.
Written Instructions
To redeem or exchange all or part of your Shares in writing, your request should be sent to one of the addresses listed under “Doing Business with Janus Henderson.” Requests or documents received in a language other than English may be inadvertently delayed or returned due to an inability to accurately translate the intended instructions. Please include the following information:
the name of the Janus Henderson fund(s) being redeemed or exchanged;
the account number(s);
the amount of money or number of shares being redeemed or exchanged;
the name(s) on the account;
the signature(s) of one or more registered account owners; and
your daytime telephone number.
Signature Guarantee
A signature guarantee for each registered account owner is required if any of the following is applicable:
You request a redemption by check above a certain dollar amount.
27 | Janus Investment Fund

You would like a check made payable to anyone other than the shareholder(s) of record.
You would like a check mailed to an address that has been changed within 10 days of the redemption request.
You would like a check mailed to an address other than the address of record.
You would like your redemption proceeds sent to a bank account other than a bank account of record.
The Fund reserves the right to require a signature guarantee under other circumstances or to reject or delay a redemption on certain legal grounds.
A signature guarantee may be refused if any of the following is applicable:
It does not appear valid or in good form.
The transaction amount exceeds the surety bond limit of the signature guarantee.
The guarantee stamp has been reported as stolen, missing, or counterfeit.
How to Obtain a Signature Guarantee
A signature guarantee assures that a signature is genuine. The signature guarantee protects shareholders from unauthorized account transfers. The following financial institutions may guarantee signatures: banks, savings and loan associations, trust companies, credit unions, broker-dealers, and member firms of a national securities exchange. Call your financial institution to see if it has the ability to guarantee a signature. A signature guarantee cannot be provided by a notary public.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.The Fund is required to disclose its complete holdings in the annual and semiannual financial statements included in Form N-CSR. In addition, the Fund is required to disclose its complete holdings in a monthly report on Form N-MFP within 5 business days after each month end. Form N-CSR filings and Form N-MFP reports (i) are available on the SEC’s website at http://www.sec.gov and (ii) are available without charge, upon request, by calling a Janus Henderson representative at 1-800-525-3713 (toll free). Holdings are generally posted within 5 business days after each month end under Full Holdings for the Fund at janushenderson.com/reports.
Top Holdings.The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation) and specific portfolio level performance attribution information and statistics monthly with a 15-day lag.
Full portfolio holdings will be available monthly and will remain on the Janus Henderson websites for at least 6 months on a rolling basis and will link to the Fund’s Form N-MFP filing available on the SEC website. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s SAI.

28 | Janus Investment Fund

Bank Account Changes
For the easiest way to change your bank account of record or add new bank account information to your account, visit janushenderson.com/individual. You may also send a written request signed by the shareholder of record or by each shareholder of record if more than one. Certain accounts may require a written notice and, in some instances, bank privileges may not be available. If multiple account owners are named on the added bank account, at least one name on the bank account must match one name on the Fund account. There may be a delay in the payment of your redemption proceeds if you request a redemption by electronic transfer to a new bank or bank account.
You may revoke the authorization to use your bank account information at any time by visiting janushenderson.com/individual, or by sending a written request by mail (Janus Henderson, P.O. Box 219109, Kansas City, MO 64121-9109), or by telephone at 1-800-525-3713. Your request will be processed within a reasonable amount of time upon its receipt.
Check Writing Privilege
Check writing privileges are available for the Fund. Checkbooks will be issued to shareholders who have completed a Signature Draft Card, which is sent in the new account welcome package, or who call a Janus Henderson representative. (There is no check writing privilege for retirement accounts.) Your checkbook will be mailed approximately 10 days after the check writing privilege is requested. You may order checks any time at janushenderson.com/individual. Checks may be written for $250 or more per check. Purchases made by check or automated investment may not be redeemed by a redemption check until the 15-day hold period has passed. In addition, checks presented against uncollected or insufficient funds in the Fund may be returned unpaid. All checks written on the account must be signed by all account holders unless otherwise specified on the original application or the subsequent Signature Draft Card. The Fund reserves the right to terminate or modify the check writing privilege at any time. These checks may not be used to initiate online banking, bill payment, or other electronic debits from your Fund account.
If you write a check for the Fund and the check is presented for payment when a liquidity fee is in effect, the applicable liquidity fee will be redeemed from your account and the face value of the check will be paid to the payee (assuming that there are sufficient funds available in your account after the liquidity fee is redeemed and the check is otherwise in correct form).
Distributions
Generally, all income dividends and capital gains distributions will automatically be reinvested in your Fund account. If you wish to change your distribution option, please visit janushenderson.com/individual, call a Janus Henderson representative, or send a written request signed by one or more shareholder(s) of record.
Your non-retirement Fund account distribution checks may be reinvested in your Fund account if you do not cash them within one year of the date they were written. No interest will accrue on amounts represented by uncashed distribution or redemption checks.
Involuntary Redemptions
The Fund reserves the right to close an account if the shareholder is deemed to engage in activities which are illegal or otherwise believed to be detrimental to the Fund. This includes, but is not limited to, accounts that the Fund or its agents believe are engaged in market timing. Any time shares are redeemed in a taxable account, it is considered a taxable event. You are responsible for any tax liabilities associated with an involuntary redemption of your account.
Lost (Unclaimed/Abandoned) Accounts
It is important that the Fund maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund as undeliverable. Based upon statutory requirements for returned mail, the Adviser will attempt to locate the shareholder or rightful owner of the account. If the Adviser is unable to locate the shareholder, then the Adviser is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.
29 | Janus Investment Fund

Online and Telephone Transactions
You may initiate many transactions through janushenderson.com/individual or by calling Janus Henderson XpressLine. You may also contact a Janus Henderson representative. Generally all new accounts automatically receive online and telephone transaction privileges including redemption privileges. If you do not want to receive these privileges, please call a Janus Henderson representative. The Fund and its agents will not be responsible for any losses, costs, or expenses resulting from unauthorized transactions when reasonable procedures designed to verify the identity of the online user or caller are followed.
Your ability to access your account or transact business electronically may be impacted due to unexpected circumstances, such as system outages, or during periods of increased web activity. For example, periods of substantial market change or other unexpected events can contribute to high call volumes, which may delay your ability to reach a Janus Henderson representative by telephone.
If you experience difficulty transacting business with us through a particular method, please consider using an alternate method, such as visiting janushenderson.com/individual, calling Janus Henderson XpressLine, contacting a Janus Henderson representative by telephone, or sending written instructions to complete your transaction. Please remember that purchase, exchange, or redemption requests must be received in good order by the Fund or its agents prior to the close of the trading session of the NYSE in order to receive that day’s NAV.
Your account information, including online credentials, should be kept private, and you should immediately review any account statements that you receive from Janus Henderson. Someone other than you could act on your account if that person is able to provide the required identifying information. Contact Janus Henderson immediately about any transactions you believe to be unauthorized.
Registration Changes
To change the name on an account, the shares are generally transferred to a new account. In some cases, legal documentation may be required. Please visit janushenderson.com/individual or call a Janus Henderson representative for further instructions.
Statements, Reports, and Prospectuses
We will send you a confirmation upon the completion of individual account transactions. We will also send you quarterly account statements detailing financial transactions on open accounts processed year-to-date. Systematic transactions are confirmed on quarterly statements unless otherwise requested. Confirmations and quarterly account statements will be sent to the account address of record unless you have elected to receive online statements. The Fund reserves the right to charge a fee for additional account statement requests.
At account setup, or any time thereafter, you may elect (at janushenderson.com/edelivery) to discontinue physical delivery of quarterly account statements and/or confirmations, and instead receive an e-mail notification when they are available online. All statements are available online regardless of your delivery option elections (to view, you must first establish online access at janushenderson.com/individual).
The Fund produces shareholder reports semiannually, and updates its prospectus annually. You may elect to receive shareholder reports and prospectus updates electronically at janushenderson.com/edelivery. The Fund’s fiscal year ends June 30.
Unless you instruct Janus Henderson otherwise by contacting a Janus Henderson representative, the Fund will mail only one report or prospectus to your address of record (“household”), even if more than one person in your household has a Fund account. This process, known as “householding,” reduces the amount of mail you receive and helps lower Fund expenses. If you decide that you no longer want the mailing of these documents to be combined with the other members of your household, please call a Janus Henderson representative or send a written request signed by one or more shareholder(s) of record. Individual copies will be sent within thirty (30) days after the Fund receives your instructions.
Taxpayer Identification Number
On the application or other appropriate forms, you may be asked to certify that your Social Security or employer identification number is correct and that you are not subject to backup withholding for failing to report income to the IRS. If you are subject to backup withholding, or you did not certify your taxpayer identification number, the IRS requires the Fund to withhold a certain percentage (at the currently applicable rate) of any dividends paid and redemption or exchange proceeds. In addition to this backup withholding, you may be subject to a $50 fee to reimburse the Fund for any penalty that the IRS may impose.
30 | Janus Investment Fund

Temporary Suspension of Services
The Fund or its agents may, in case of emergency, temporarily suspend telephone transactions and other shareholder services. As previously noted, the Fund may postpone payment of redemption proceeds for up to seven calendar days. In addition, the right to require the Fund to redeem its Shares may be suspended or the date of payment may be postponed beyond seven calendar days whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable. The exchange privilege may also be suspended in these circumstances.
In addition, a temporary hold may be placed on the disbursement of redemption proceeds from an account if there is a reasonable belief that financial exploitation of a Specified Adult (as defined below) has occurred, is occurring, has been attempted, or will be attempted. This temporary delay will be for an initial period of no more than 15 business days while we conduct an internal review of the facts and circumstances of the suspected financial exploitation. If our internal review supports our belief that actual or attempted financial exploitation has occurred or is occurring, we may extend the hold for up to 10 additional business days. Both the initial and subsequent hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (i) a natural person age 65 and older, or (ii) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests. We may not be aware of factors suggesting financial exploitation of a Specified Adult and may not be able to identify Specified Adults in all circumstances. Furthermore, we are not required to delay the disbursement of redemption proceeds and do not assume any obligation to do so.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Agency discount notes are U.S. Government securities that are issued by a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. The Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable amount master demand notes are demand obligations that permit the investment of fluctuating amounts at varying market rates of interest pursuant to arrangements between the issuer and a commercial bank acting as agent for the payee of such notes whereby both parties have the right to vary the amount of the outstanding indebtedness on the notes. These notes are direct lending arrangements between the lender and borrower and there is no secondary market for them. The principal plus accrued interest is redeemable at any time, however. This right to redeem the notes depends on the ability of the borrower to make the specified payments on demand.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Other Investments, Strategies, and/or Techniques
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.

EXAMPLE:
The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Principal investment strategies
The Fund pursues its investment objectives by investing primarily in high quality debt obligations and obligations of financial institutions. Debt obligations may include commercial paper, notes, and bonds. Obligations of financial institutions include certificates of deposit and time deposits. The Fund also intends to invest in repurchase agreements including those secured by U.S. Government agencies. Some government agencies backed by the full faith and credit of the United States are supported by the issuer’s ability to borrow from the U.S. Treasury, some are supported only by the credit of the issuer, and some are supported by the United States in some other way.
The Fund will:
invest in high-quality, short-term money market instruments that present minimal credit risks, as determined by the Adviser
invest only in U.S. dollar-denominated instruments that have a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended)
maintain a dollar-weighted average portfolio maturity of 60 days or less and maintain a dollar-weighted average portfolio life (portfolio maturity measured without reference to any maturity shortening provisions of adjustable rate securities by reference to their interest rate reset dates) of 120 days or less
Principal investment risks
Money Market Risk.You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your Shares. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Adviser is not required to reimburse the Fund for losses, and you should not expect
2 | Janus Henderson Money Market Fund

that the Adviser will provide financial support to the Fund at any time, including during periods of market stress. Accordingly, if the value of Fund Shares were to fall below $1.00 per share, there is no guarantee that the Adviser or its affiliates would protect the Fund or redeeming shareholders against any loss of principal.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations. The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Interest Rate Risk.Although the Fund seeks to invest only in high-quality, short-term money market instruments, there is a risk that the value of the securities it holds will fall as a result of the changes in interest rates. Rising interest rates could cause the value of the Fund’s investments to decline, and a decline in interest rates is likely to cause the Fund’s yield to decline. During periods of unusually low or negative interest rates, the Fund’s yield may approach or fall below zero. Such low interest rate environments may prevent the Fund from providing a positive yield or could impair the Fund’s ability to maintain the value of your investment at $1.00 per share. Over time, the real value of the Fund’s yield may be eroded by inflation.
Retail Money Market Fund Risk.The Fund is classified as a “retail money market fund,” as such term is defined in or interpreted under the rules governing money market funds. A retail money market fund is a money market fund that has policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. The Fund may impose a discretionary liquidity fee of up to 2% on Fund redemptions if the Fund’s Board of Trustees, or its delegate, determines that a liquidity fee is in the best interests of the Fund. The Board of Trustees has delegated liquidity fee determinations to the Adviser, subject to Board guidelines and oversight.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield.
Collateral Risk.With respect to collateral received in repurchase transactions or other investments, the Fund may have significant exposure to financial services, mortgage markets, and government agencies not secured by the full faith and credit of the United States. Such exposure, depending on market conditions, could have a negative impact on the Fund, including minimizing the value of any collateral.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.

Commercial Paper Risk.Commercial paper is a debt obligation usually issued by corporations in order to finance their current operations. Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.
U.S. Government Securities Risk.Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security.
Performance information
The following information provides some indication of the risks of investing in the Fund by showing how the Fund’s performance has varied over time. Class T Shares (formerly named Class J Shares, the initial share class) of the Fund commenced operations with the Fund’s inception. The performance shown for Class T Shares is calculated using the fees and expenses of Class T Shares in effect during the periods shown, net of any applicable fee and expense limitations or waivers.
The bar chart depicts the change in performance from year to year during the periods indicated. The table shows how the Fund’s returns over different periods average out. All figures assume reinvestment of dividends and distributions. For certain periods, the Fund’s performance reflects the effect of expense waivers. Without the effect of these expense waivers, the performance shown would have been lower.
The Fund’s past performance does not necessarily indicate how it will perform in the future. Updated performance information is available at janushenderson.com/performance or by calling 1-877-335-2687.

Purchase and sale of Fund shares
Investments in the Fund are limited to accounts beneficially owned by natural persons. The Fund reserves the right to involuntarily redeem Fund Shares in any account that are not beneficially owned by natural persons, after providing notice.
Minimum Investment Requirements
The minimum investment for Class T Shares is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Shareholders who invest through financial intermediaries with supermarket and/or self-directed brokerage accounts that maintain omnibus accounts and charge asset-based service fees may not be subject to the $2,500 minimum investment requirement noted above.
Purchases, exchanges, and redemptions can generally be made only through institutional channels, such as financial intermediaries and retirement platforms. You should contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund. Requests must be received in good order by the Fund or its agents (financial intermediary or plan sponsor, if applicable) prior to the close of the trading session of the New York Stock Exchange in order to receive that day’s net asset value. For additional information, refer to “Purchases,” “Exchanges,” and/or “Redemptions” in the Prospectus.
Tax information
The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).
Payments to broker-dealers and other financial intermediaries
If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund or its distributor (or its affiliates) may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment or to recommend one share class over another. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional information about the Fund
Fees and expenses
Please refer to the following important information when reviewing the “Fees and Expenses of the Fund” table in the Fund Summary of the Prospectus. The fees and expenses shown were determined based on average net assets as of the fiscal year ended June 30, 2024.
“Annual Fund Operating Expenses” are paid out of the Fund’s assets and include fees for portfolio management and administrative services, including recordkeeping, subaccounting, and other shareholder services. You do not pay these fees directly but, as the Example in the Fund Summary shows, these costs are borne indirectly by all shareholders through the management fee and the administration fee paid to the Adviser.
The “Management Fee” is the investment advisory fee rate paid by the Fund to the Adviser. Refer to “Management Expenses” in this Prospectus for additional information with further description in the Statement of Additional Information (“SAI”).
“Other Expenses” for the Fund include a class-level administration fee of 0.28% of the average daily net assets of Class T Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping and registration functions and also to pay for costs such as shareholder servicing and custody.
The Adviser may voluntarily waive and/or reimburse fees to the extent necessary to assist the Fund in attempting to maintain a yield of at least 0.00%. Any waivers and reimbursements are voluntary and could change or be terminated at any time at the discretion of the Adviser. There is no guarantee that the Fund will maintain a positive yield.
All expenses in the Fund’s “Fees and Expenses of the Fund” table are shown without the effect of expense offset arrangements. Pursuant to such arrangements, credits realized as a result of uninvested cash balances are used to reduce custodian and transfer agent expenses.
Additional investment strategies and general portfolio policies
The Fund’s Board of Trustees (“Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days before making any such change it considers material. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.
This section takes a closer look at investment strategies and general policies that apply to the Fund. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent. The Fund is subject to certain specific Securities and Exchange Commission (“SEC”) rule requirements. Among other things, the Fund is limited to investing in U.S. dollar-denominated instruments with a remaining maturity of 397 days or less (as calculated pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended) that are determined to present minimal credit risk.
Security Selection
In selecting securities for the Fund’s portfolio, portfolio management focuses on securities that offer liquidity and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.
Debt Obligations
The Fund may invest in U.S. dollar-denominated debt obligations. Debt obligations include:
commercial paper
notes and bonds
variable amount master demand notes (the payment obligations on these instruments may be backed by securities, swap agreements or other assets, by a guarantee of a third party, or solely by the unsecured promise of the issuer to make payments when due)
privately issued commercial paper or other securities that are restricted as to disposition under the federal securities laws

Demand Features
Demand features give the Fund the right to resell securities at specified periods prior to their maturity dates. Demand features may shorten the life of a variable or floating rate security or preferred stock, enhance the instrument’s credit quality, and provide a source of liquidity. Demand features are often issued by third party financial institutions, generally domestic and foreign banks. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the banks supporting the Fund’s investments. This will result in exposure to risks pertaining to the banking industry, including the foreign banking industry. Brokerage firms and insurance companies also provide certain liquidity and credit support.
Liquidity
The Fund has adopted liquidity requirements (measured at the time of purchase) as noted:
Daily liquidity.The Fund will invest at least 25% of its total assets in “daily liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within one business day, and/or amounts receivable and due unconditionally within one business day on pending sales of portfolio securities.
Weekly liquidity.The Fund will invest at least 50% of its assets in “weekly liquid assets,” which generally include cash (including demand deposits), direct obligations of the U.S. Government, agency discount notes with remaining maturities of 60 days or less, and securities (including repurchase agreements) that will mature or are subject to a demand feature that is exercisable and payable within five business days.
The Fund will limit its investments in illiquid securities to 5% or less of its total assets.
Mortgage- and Asset-Backed Securities
The Fund may purchase fixed or variable rate commercial or residential mortgage-backed securities issued by the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or other governmental or government-related entities. Ginnie Mae’s guarantees are backed by the full faith and credit of the U.S. Government, which means that the U.S. Government guarantees that the interest and principal will be paid when due. Fannie Mae and Freddie Mac securities, as well as the securities of other government or government-related entities, are not backed by the full faith and credit of the U.S. Government.
The Fund may also purchase mortgage- and asset-backed securities through single- and multi-seller conduits, collateralized debt obligations, structured investment vehicles, and other similar securities. Asset-backed securities may be backed by various consumer obligations, including automobile loans, equipment leases, credit card receivables, or other collateral.
Obligations of Financial Institutions
The Fund may invest in obligations of financial institutions. Examples of obligations of financial institutions include:
negotiable certificates of deposit, bankers’ acceptances, time deposits, and other obligations of U.S. banks (including savings and loan associations) having total assets in excess of one billion dollars and U.S. branches of foreign banks having total assets in excess of ten billion dollars
Eurodollar and Yankee bank obligations (Eurodollar bank obligations are dollar-denominated certificates of deposit or time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee bank obligations are dollar-denominated obligations issued in the U.S. capital markets by foreign banks.)
other U.S. dollar-denominated obligations of foreign banks having total assets in excess of ten billion dollars that the Adviser believes are of an investment quality comparable to obligations of U.S. banks in which the Fund may invest
The Fund may focus its investments in the financial services sector.
Participation Interests
A participation interest gives the Fund a proportionate, undivided interest in underlying debt securities and usually carries a demand feature.
7 | Janus Investment Fund

Repurchase Agreements
The Fund may enter into collateralized repurchase agreements by cash or U.S. Government securities. Repurchase agreements are transactions in which the Fund purchases securities and simultaneously commits to resell those securities to the seller at an agreed-upon price on an agreed-upon future date. The repurchase price reflects a market rate of interest.
U.S. Government Securities
The Fund may invest in U.S. Government securities. U.S. Government securities include those issued directly by the U.S. Treasury and those issued or guaranteed by various U.S. Government agencies and instrumentalities. Some government securities are backed by the full faith and credit of the United States. Other government securities are backed only by the rights of the issuer to borrow from the U.S. Treasury. Others are supported by the discretionary authority of the U.S. Government to purchase the obligations. Certain other government securities are supported only by the credit of the issuer.
Variable and Floating Rate Securities
The Fund may invest in securities which have variable or floating rates of interest. These securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to an interest rate index or market interest rate. Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness.
Risks of the Fund
The value of your investment may vary over time, and you may lose money by investing in the Fund. The following information is intended to help you better understand some of the risks of investing in the Fund, including those risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.
Commercial Paper Risk.Commercial paper is usually repaid at maturity by the issuer from the proceeds of the issuance of new commercial paper. As a result, investments in commercial paper are subject to the risk the issuer cannot issue enough new commercial paper to satisfy its outstanding commercial paper, also known as rollover risk. In addition, under certain circumstances commercial paper may become illiquid or may suffer from reduced liquidity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
Counterparty Risk.Fund transactions involving a counterparty are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be exposed to counterparty risk through its investments in certain securities, including, but not limited to, repurchase agreements and debt securities. The Fund intends to enter into financial transactions with counterparties that the Adviser believes to be creditworthy at the time of the transaction. There is always the risk that the Adviser’s analysis of a counterparty’s creditworthiness is incorrect or may change due to market conditions. To the extent that the Fund focuses its transactions with a limited number of counterparties, it will have greater exposure to the risks associated with one or more counterparties.
Credit Quality Risk.The value of the securities which the Fund holds may fall based on an issuer’s actual or perceived creditworthiness, or an issuer’s ability to meet its obligations. The credit quality of the Fund’s holdings can change rapidly in certain market environments and any downgrade or default of a portfolio security could cause the Fund’s yield to fall or cause the value of the Fund’s Shares to fall below $1.00 per share.
Currency Risk.To the extent the Fund holds a U.S. dollar-denominated foreign security, its value may be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.
Financial Services Sector Risk.To the extent the Fund focuses its investments on issuers in the financial services sector, the Fund will have more exposure to the risks inherent to the financial services sector. Financial services companies may be adversely affected by changes in regulatory framework or interest rates that may negatively affect financial services businesses; exposure of a financial institution to a nondiversified or concentrated loan portfolio; exposure to financial leverage and/or
8 | Janus Investment Fund

investments or agreements that, under certain circumstances, may lead to losses; and the risk that a market shock or other unexpected market, economic, political, regulatory, or other event, including a banking crisis or financial emergency, might lead to a sudden decline in the values of most or all financial services companies. In addition, a decline in the credit quality of an issuer, the provider of credit support, may also have a negative effect on the Fund.
Liquidity Risk.The liquidity of the securities which the Fund holds may deteriorate rapidly due to credit events affecting one or more issuers or guarantors or due to general market conditions and a lack of willing buyers. In such cases, the Fund may have to accept a lower price or may be unable to sell a security. An inability to sell one or more securities may negatively affect the Fund’s ability to maintain a $1.00 share price or prevent the Fund from being able to take advantage of other investment opportunities. Additionally, adverse market conditions impacting the trading of the value of money market instruments and/or an unusually high volume of redemption requests could cause the Fund to be unable to pay redemption proceeds within a short period of time. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s ability to maintain the value of your investment at $1.00 per share.
Market Risk.The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. For capital preservation and liquidity, the Fund may have a greater concentration in short-term securities including, but not limited to, investing up to all of its assets in overnight securities, which may result in a reduction of the Fund’s yield. Further, regardless of how well securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions that have a significant effect on issuers. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, conflicts, including related sanctions, social unrest, financial institution failures, and economic recessions, could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant impact on the global economies and financial markets.
Armed Conflict.Recent such examples include conflict, loss of life, and disaster connected to ongoing armed conflict between Russia and Ukraine in Europe and Hamas and Israel in the Middle East. The extent and duration of each conflict, resulting sanctions, and resulting future market disruptions in each region are impossible to predict, but could be significant and have a severe adverse effect, including significant negative impacts on the United States and broader global economy and the markets for certain securities and commodities.
Mortgage- and Asset-Backed Securities Risk.Mortgage- and asset-backed securities represent interests in “pools” of commercial or residential mortgages or other assets, including consumer loans or receivables. In the event the underlying loans are not paid, the securities’ issuer could be forced to sell the assets and recognize losses on such assets, which could impact the Fund’s yield and return. Mortgage- and asset-backed securities tend to be more sensitive to changes in interest rates than other types of debt securities. Investments in mortgage- and asset-backed securities are subject to both extension risk, where during periods of rising interest rates, certain debt obligations may be paid off substantially slower than originally expected, and prepayment risk, where during periods of falling interest rates, certain debt obligations may be paid off quicker than originally anticipated. These risks may reduce the Fund’s returns. In addition, investments in certain mortgage- and asset-backed securities may be subject to a higher degree of credit risk, valuation risk, and liquidity risk than various other types of fixed-income securities.
Participation Interests Risk.If the Fund purchases a participation interest, it typically will have a contractual relationship with the lender and not with the borrower. The Fund may only be able to enforce its rights through the lender and may assume the credit risk of both the borrower and the lender, or any other intermediate participant. The Fund may have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender and only upon receipt by the lender of the payments from the borrower. The failure by the Fund to receive scheduled interest or principal payments may adversely affect the income of the Fund and may likely reduce the value of its assets, which would be reflected by a reduction in the Fund’s net asset value.
Repurchase Agreement Risk.Repurchase agreements involve the risk that the seller will fail to repurchase the security, as agreed. In that case, the Fund will bear the risk of market value fluctuations until the security can be sold and may encounter delays and incur costs in liquidating the security. While it is not possible to eliminate all risks from these transactions, it is the policy of the Fund to limit repurchase agreements to those parties whose creditworthiness has been reviewed and found satisfactory. There is no guarantee that the Adviser’s analysis of the creditworthiness of the counterparty will be accurate, and
9 | Janus Investment Fund

the underlying collateral involved in the transaction can expose the Fund to additional risk regardless of the creditworthiness of the parties involved in the transaction.
Sovereign Debt Risk.Foreign, Eurodollar, and, to a limited extent, Yankee bank obligations are subject to certain sovereign debt risks. One such risk is the possibility that a foreign government might prevent dollar-denominated funds from flowing across its borders. Other risks include: adverse political and economic developments in a foreign country, the extent and quality of government regulation of financial markets and institutions, the imposition of foreign withholding taxes, and expropriation or nationalization of foreign issuers.
U.S. Government Securities Risk.Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets. Certain U.S. Government securities are not guaranteed or backed by the full faith and credit of the United States. For these securities, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment. Such securities may involve increased risk of loss of principal and interest compared to government debt securities that are backed by the full faith and credit of the United States.
Variable and Floating Rate Demand Notes Risk.Variable and floating rate securities are subject to changes in value based on changes in market interest rates or changes in the issuer’s or guarantor’s creditworthiness. Demand features, which are often issued by third-party financial institutions, may shorten the life of a variable or floating rate security. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the third-party financial institutions supporting the Fund’s investments. In addition, the absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults and the third party is unable to fulfill its liquidity or guarantee demand feature obligations.

Management of the Fund
Investment adviser
Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.
The Adviser (together with its predecessors and affiliates) has served as investment adviser to the Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson mutual funds, as well as the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.
The Trust and the Adviser have received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Board of Trustees (“Trustees”), to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the Investment Company Act of 1940, as amended) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).
Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the Fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.
The Adviser furnishes certain administration, compliance, and accounting services to the Fund, including providing office space for the Fund and providing personnel to serve as officers to the Fund. The Adviser generally pays the salaries, fees, and expenses of Fund officers with respect to services provided to the Fund, although some expenses related to compensation payable to the Fund’s Chief Compliance Officer and compliance staff are shared with the Fund.
Management expenses
The Fund pays the Adviser an investment advisory fee and incurs other expenses, including legal and auditing fees and Independent Trustees’ fees and expenses. The Fund’s investment advisory fee is calculated daily and paid monthly. The Fund’s advisory agreement details the investment advisory fee and other expenses that the Fund pays.
The following table reflects the Fund’s contractual investment advisory fee rate (expressed as an annual rate), as well as the actual investment advisory fee rate paid by the Fund to the Adviser (net of fee waivers). The rate shown is a fixed rate based on the Fund’s average daily net assets.

Administration fee
The Fund pays an administration fee of 0.28% of the average daily net assets of Class T Shares to compensate the Adviser for providing certain administration services including, but not limited to, recordkeeping, fund accounting, preparation of reports and prospectuses distributed to current shareholders, and registration functions. This administration fee also covers expenses including, but not limited to, custody, transfer agency, shareholder servicing, and provision of office facilities and personnel necessary to carry on the business of the Fund. The administration fee may also be used to pay financial intermediaries for subaccounting, order processing for omnibus or networked accounts, or other shareholder servicing. Order processing includes the submission of transactions by financial intermediaries through the National Securities Clearing Corporation or similar systems, or those processed on a manual basis.
Portfolio management
Janus Henderson Money Market Fund
Effective February 1, 2025, Co-Portfolio Managers Andrew Forman and Garrett Strum will be responsible for the day-to-day management of the Fund. Mr. Strum, as Lead Portfolio Manager, has the authority to exercise final decision-making on the overall portfolios.
Andrew Forman is Co-Portfolio Manager of Janus Henderson Money Market Fund, which he has co-managed since February 2025. He is also Portfolio Manager of other Janus Henderson accounts. Mr. Forman joined the Adviser in 2013. He holds a Bachelor of Arts degree in Economics with a minor in Atmospheric and Oceanic Sciences from the University of Colorado.
Garrett Strum is Executive Vice President and Lead Portfolio Manager of Janus Henderson Money Market Fund, which he has managed or co-managed since May 2017. He is also Portfolio Manager of other Janus Henderson accounts and performs duties as an analyst. Mr. Strum holds a Bachelor of Science degree in Business with concentrations in Finance and Real Estate from Colorado State University.
Conflicts of Interest
The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades. Additionally, the Adviser manages the Janus Henderson “funds of funds,” which are funds that invest primarily in other mutual funds that are managed by the Adviser. Because the Adviser manages the Janus Henderson “funds of funds” and the Janus Henderson funds, it is subject to certain potential conflicts of interest when allocating the assets of a Janus Henderson “fund of funds” among such Janus Henderson funds. A further discussion of potential conflicts of interest and a discussion of certain procedures intended to mitigate such potential conflicts are contained in the Fund’s SAI.

Other information
CLOSED FUND POLICIES
The Fund may limit sales of its Shares to new investors. If sales of the Fund are limited, it is expected that existing shareholders invested in the Fund would be permitted to continue to purchase Shares through their existing Fund accounts and to reinvest any dividends or capital gains distributions in such accounts, absent highly unusual circumstances. Requests for new accounts into a closed fund would be reviewed by management, taking into consideration eligibility requirements and whether the addition to the fund is believed to negatively impact existing fund shareholders. The closed fund may decline opening new accounts, including eligible new accounts, if it would be in the best interests of the fund and its shareholders. If applicable, additional information regarding general policies and exceptions can be found in a closed fund’s prospectuses.
Investments in the Fund are limited to accounts beneficially owned by natural persons. In order to make an initial investment in the Fund, investors may be required to provide certain information (e.g., Social Security number or government-issued identification) to demonstrate eligibility to invest in the Fund. The Fund reserves the right to involuntarily redeem Fund Shares in any account that are not beneficially owned by natural persons, after providing notice.
LIQUIDATION/REORGANIZATION OF A FUND
It is important to know that, pursuant to the Trust’s Amended and Restated Agreement and Declaration of Trust, the Trustees have the authority to merge, liquidate, and/or reorganize a fund into another fund without seeking shareholder vote or consent.
DISTRIBUTION OF THE Fund
The Fund is distributed by Janus Henderson Distributors US LLC (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Distributions and taxes
Distributions
To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually. A return of capital distribution is tax-free to the extent of your basis in your shares and thereafter is treated as a capital gain if you hold your shares as a capital asset. Because a return of capital distribution reduces the basis of your shares, a return of capital distribution may result in a higher capital gain or a lower capital loss when you sell your shares held in a taxable account. Distributions are made at the class level, so they may vary from class to class within the Fund.
Dividends representing substantially all of the net investment income and any net realized gains on sales of securities are declared daily (Saturdays, Sundays, and holidays included) and distributed as of the last business day of each month. If a month begins on a Saturday, Sunday, or holiday, dividends for those days are declared and distributed at the end of the preceding month.
Purchase orders received prior to 4:00 p.m. (New York time) on a bank business day (a day when both the New York Stock Exchange (“NYSE”) and the Federal Reserve Banks are open) will begin to accrue dividends on the following bank business day.
Redemption requests received prior to 4:00 p.m. (New York time) on a bank business day will receive that day’s dividends. Proceeds of such redemption will normally be sent on the next bank business day.
The Fund reserves the right to require purchase and redemption requests and payments prior to these times on days when the bond markets or NYSE close early.
For your convenience, distributions of dividends and capital gains are automatically reinvested in additional Shares of the Fund. To receive distributions in cash, contact your financial intermediary. Whether reinvested or paid in cash, the distributions may be subject to taxes, unless your shares are held in a qualified tax-advantaged plan or account.
TAXES
As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.
Taxes on Distributions
Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long-term capital gain rates, provided certain holding period and other requirements are satisfied. Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. In certain states, a portion of the distributions (depending on the sources of the Fund’s income) may be exempt from state and local taxes. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (the “IRS”).
Distributions made by the Fund with respect to Shares purchased through a qualified retirement plan will generally be exempt from current taxation if left to accumulate within the qualified plan. Generally, withdrawals from qualified plans may
14 | Janus Investment Fund

be subject to federal income tax at ordinary income rates and, if made before age 59 12, a 10% penalty tax may be imposed. The federal income tax status of your investment depends on the features of your qualified plan. For further information, please contact your plan sponsor or tax adviser.
Taxes on Sales or Exchanges
Any time you sell or exchange shares of the Fund in a taxable account, it is considered a taxable event. For federal income tax purposes, an exchange is treated the same as a sale. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility. Your ability to deduct capital losses may be limited under the Internal Revenue Code.
The Fund may be required to withhold U.S. federal income tax on all distributions and redemption proceeds to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS (or the Fund has been notified by the IRS) that they are subject to backup withholding. The current backup withholding rate is applied.
If a shareholder does not meet the requirements of the Foreign Account Tax Compliance Act (“FATCA”), the Fund may be required to impose a 30% U.S. withholding tax on distributions and proceeds from the sale or other disposition of shares in the Fund. FATCA withholding will generally apply to payments of dividends from net investment income, payments of gross proceeds from sales of Fund shares, and distributions of net capital gains. Proposed Treasury regulations, however, generally eliminate withholding under FATCA on gross proceeds, which include certain capital gains distributions and gross proceeds from a sale or disposition of Fund shares. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. Shareholders should consult their individual tax advisers regarding the possible implications of FATCA.
For Shares purchased on or after January 1, 2012 and sold thereafter from a taxable account, your intermediary will report cost basis information to you and to the IRS. Your intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your intermediary’s default method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.
A liquidity fee imposed by the Fund will reduce the amount you will receive upon the redemption of your Shares, and will decrease the amount of any capital gain or increase the amount of any capital loss you will recognize as a result of such redemption. There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by money market funds, and such tax treatment may be the subject of future guidance issued by the IRS. If the Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Taxation of the Fund
Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes. If the Fund is eligible, it may from year to year make the election permitted under Section 853 of the Internal Revenue Code to pass through such taxes to shareholders. If the Fund makes such election, foreign taxes paid by the Fund will be reported to shareholders as income and shareholders may claim a tax credit or deduction for such taxes, subject to certain limitations. If such an election is not made, any foreign taxes paid or accrued will represent an expense to the Fund.
Certain fund transactions may involve short sales, futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.
The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important that the Fund meets these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in partnerships, it may be subject to state tax liabilities.

Shareholder’s guide
With certain exceptions, the Fund is generally available only to shareholders residing in the United States and employees of the Adviser or its affiliates. For purposes of this policy, the Fund requires that a shareholder and/or entity be a U.S. citizen residing in the United States or a U.S. Territory (including overseas U.S. military or diplomatic addresses) or a resident alien residing in the United States or a U.S. Territory with a valid U.S. Taxpayer Identification Number to open an account with the Fund.
Investments in the Fund are limited to accounts beneficially owned by natural persons. In order to make an initial investment in the Fund, the Fund requires that a shareholder provide certain information (e.g., Social Security number, permanent street address, date of birth, or government-issued identification) that confirms your eligibility to invest in the Fund. Accounts that are not beneficially owned by natural persons, such as business and limited liability company accounts, charitable or financial organizations, and corporate and S-Corp accounts, are not eligible to invest in the Fund, and will be involuntarily redeemed from the Fund after having been provided sufficient notice.
Class T Shares are available through certain financial intermediary platforms including, but not limited to, mutual fund wrap fee programs, managed account programs, asset allocation programs, bank trust platforms, as well as certain retirement platforms. In addition, the Shares may be available through certain financial intermediaries who have an agreement with the Adviser or its affiliates to offer the Shares on their supermarket platforms.
Pricing of fund shares
The per share net asset value (“NAV”) for each class is computed by dividing the total value of assets allocated to the class, less liabilities allocated to that class, by the total number of outstanding shares of the class. The Fund’s NAV is calculated as of the close of the trading session of the NYSE (normally 4:00 p.m. New York time) each day that the NYSE is open (“business day”). However, the time at which the Fund’s NAV is calculated may be changed if trading on the NYSE is restricted, the NYSE closes at a different time, or as permitted by the SEC. The value of the Fund’s holdings may change on days that are not business days in the United States and on which you will not be able to purchase or redeem the Fund’s Shares.
All purchases and redemptions will be duly processed at the NAV next calculated after your request is received in good order by the Fund or its agents. In order to receive a day’s price, your order must be received in good order by the Fund or its agents by the close of the trading session of the NYSE. The Fund reserves the right to require purchase and/or redemption requests from a financial intermediary or plan sponsor prior to this time on days when the bond markets or the NYSE close early. Your financial intermediary may charge you a separate or additional fee for processing purchases and redemptions of Shares.
The Fund’s portfolio securities are valued at amortized cost, which approximates market value. Amortized cost valuation involves valuing an instrument at its cost and thereafter assuming a constant amortization to maturity (or such other date as permitted by Rule 2a-7) of any discount or premium. If fluctuating interest rates cause the market value of the Fund’s portfolio to deviate more than 1/2 of 1% from the value determined on the basis of amortized cost, the Trustees will consider whether any action, such as adjusting the NAV to reflect current market conditions, should be initiated to prevent any material dilutive effect on shareholders.
All purchases, exchanges, redemptions, or other account activity must be processed through your financial intermediary or plan sponsor. Your financial intermediary or plan sponsor is responsible for promptly transmitting purchase, redemption, and other requests to the Fund under the arrangements made between your financial intermediary or plan sponsor and its customers. The Fund is not responsible for the failure of any financial intermediary or plan sponsor to carry out its obligations to its customers.
Payments to financial intermediaries by the Adviser or its affiliates
With respect to other share classes not currently offered by the Fund, the Adviser or its affiliates pay fees, from their own assets, to selected brokerage firms or other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services. Such payments may be based on gross sales, assets under management, or transactional charges, or on a combination of these factors. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different financial intermediaries. The Adviser and its affiliates consider a number of factors in making payments to financial intermediaries.
16 | Janus Investment Fund

For Class T Shares, the Adviser, the Distributor, or their affiliates pay fees, from their own assets, to certain brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing other marketing or distribution-related services, as well as recordkeeping, subaccounting, transaction processing, other shareholder or administrative services (including payments for processing transactions via the National Securities Clearing Corporation or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees, in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. The Adviser or its affiliates may have numerous agreements to make payments to financial institutions which perform recordkeeping or other administrative services with respect to shareholder accounts.
In addition, the Adviser or its affiliates periodically share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, support for marketing materials, sales reporting, or business building programs for such financial intermediaries to raise awareness of the Fund. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.
The receipt of (or prospect of receiving) payments described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other mutual funds (or non-mutual fund investments) or to favor sales of one class of Janus Henderson funds’ shares over sales of another Janus Henderson funds’ share class, with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.
From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other mutual funds (or non-mutual fund investments).
The payment arrangements described above will not change the price an investor pays for Shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell Shares of the Fund and, if applicable, when considering which share class of the Fund is most appropriate for you. Please contact your financial intermediary or plan sponsor for details on such arrangements.
Purchases
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, you may not be able to open an account or buy additional shares.
In addition, investments in the Fund are limited to accounts beneficially owned by natural persons, which means that the Fund’s Shares can only be held by individual investors.
Purchases of Shares may be made only through financial intermediaries. Contact your financial intermediary or refer to your plan documents for information on how to invest in the Fund, including additional information on minimum initial or subsequent investment requirements. Your financial intermediary may charge you a separate or additional fee for processing purchases of Shares. Only certain financial intermediaries are authorized to receive purchase orders on the Fund’s behalf. As discussed under “Payments to Financial Intermediaries by the Adviser or its Affiliates,” the Adviser and its affiliates may make payments to brokerage firms or other financial intermediaries that were instrumental in the acquisition or retention of
17 | Janus Investment Fund

shareholders for the Fund or that provide services in connection with investments in the Fund. You should consider such arrangements when evaluating any recommendation of the Fund.
The Fund reserves the right to require purchase requests and payments from the financial intermediary or plan sponsor prior to 4:00 p.m. (New York time) on days when the bond markets or NYSE close early.
The Fund reserves the right to reject any purchase order, including exchange purchases, for any reason. The Fund is not intended for excessive trading.
In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name, date of birth, Social Security number, and permanent street address to assist in verifying your identity. You may also be asked to provide documents that may help to establish your identity. For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business, and taxpayer identification number, and you may be requested to provide information on persons with authority or control over the account, or persons who own (whether directly, indirectly, or beneficially) 25% or more of the entity, such as name, permanent street address, date of birth, and Social Security number. Until verification of an identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if it is unable to verify a shareholder’s identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about the intermediary’s Anti-Money Laundering Program.
In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.
Minimum Investment Requirements
The minimum investment for Class T Shares is $2,500 per Fund account for non-retirement accounts and $500 per Fund account for certain tax-advantaged accounts or UGMA/UTMA accounts. Investors in a defined contribution plan through a third party administrator should refer to their plan document or contact their plan administrator for additional information. Accounts held through wrap programs may not be subject to these minimums. In addition, shareholders who invest through financial intermediaries with supermarket and/or self-directed brokerage accounts that maintain omnibus accounts and charge asset-based service fees may not be subject to the $2,500 minimum investment requirement noted above. Investors should refer to their intermediary for additional information.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
The Fund reserves the right to change the amount of these minimums from time to time or to waive them in whole or in part.
Systematic Purchase Plan
You may arrange for periodic purchases by authorizing your financial intermediary to withdraw the amount of your investment from your bank account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Exchanges
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, the exchange privilege may not be available.
18 | Janus Investment Fund

Contact your financial intermediary or consult your plan documents to exchange into other funds in the Trust. Be sure to read the prospectus of the fund into which you are exchanging. An exchange from one fund to another is generally a taxable transaction (except for certain tax-advantaged accounts).
You may generally exchange Shares of the Fund for Shares of the same class of any other fund in the Trust offered through your financial intermediary or qualified plan.
You may also exchange shares of one class for another class of shares within the same fund, provided the eligibility requirements of the class of shares to be received are met. Same-fund exchanges will generally only be processed in instances where there is no CDSC on the shares to be exchanged and no initial sales charge on the shares to be received. The Fund’s fees and expenses differ between share classes. Please read the Prospectus for the share class you are interested in prior to investing in that share class. Contact your financial intermediary or consult your plan documents for additional information.
You must meet the minimum investment amount for each fund.
The Fund reserves the right to reject any exchange request and to modify or terminate the exchange privilege at any time.
Exchanges from the Fund may be subject to any liquidity fees imposed by the Fund. For more information, refer to “Information on Liquidity Fees.”
Redemptions
With certain exceptions, the Fund is generally available only to shareholders residing in the United States. Unless you meet certain residency eligibility requirements, once you close your account, you may not make additional investments in the Fund.
Redemptions, like purchases, may generally be effected only through financial intermediaries. Please contact your financial intermediary or refer to the appropriate plan documents for details. Your financial intermediary may charge a processing or service fee in connection with the redemption of Shares.
Shares of the Fund may be redeemed on any business day on which the Fund’s NAV is calculated. Redemptions are duly processed at the NAV next calculated after your redemption order is received in good order by the Fund or its agents. The Fund reserves the right to require redemption requests prior to 4:00 p.m. (New York time) on days when the bond markets or NYSE close early. Redemption proceeds will normally be sent within two business days following receipt of the redemption order. The Fund typically expects to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio holdings. In stressed market conditions, and other appropriate circumstances, redemption methods may include borrowing funds or redeeming in-kind.
The Fund reserves the right to postpone payment of redemption proceeds for up to seven calendar days. Additionally, the right to require the Fund to redeem its Shares may be suspended, or the date of payment may be postponed beyond seven calendar days, whenever: (i) trading on the NYSE is restricted, as determined by the SEC, or the NYSE is closed (except for holidays and weekends); (ii) the SEC permits such suspension and so orders; or (iii) an emergency exists as determined by the SEC so that disposal of securities or determination of NAV is not reasonably practicable.
The Fund reserves the right to annually request that intermediaries close Fund accounts that are valued at less than $100, other than as a result solely of depreciation in share value. Certain accounts held through intermediaries may not be subject to closure due to the policies of the intermediaries. You may receive written notice from your intermediary to increase your account balance to the required minimum to avoid having your account closed provided you meet certain residency eligibility requirements. Please note that you may incur a tax liability as a result of a redemption.
Large Shareholder Redemptions
Certain large shareholders, such as other funds, institutional investors, financial intermediaries, individuals, accounts, and affiliates of the Adviser, may from time to time own (beneficially or of record) or control a significant percentage of the Fund’s Shares. Redemptions by these large shareholders of their holdings in the Fund may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the recognition of taxable income to shareholders if such sales of investments result in gains, and may also increase transaction costs. In
19 | Janus Investment Fund

addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, which could lead to an increase in the Fund’s expense ratio.
Redemptions In-Kind
Shares normally will be redeemed for cash, although the Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, to accommodate a request by a particular shareholder that does not adversely affect the interests of the remaining shareholders, or in connection with the liquidation of a fund, by delivery of securities selected from its assets at its discretion. However, the Fund is required to redeem shares solely for cash up to the lesser of $250,000 or 1% of the NAV of the Fund during any 90-day period for any one shareholder. Should redemptions by any shareholder exceed such limitation, the Fund will have the option of redeeming the excess in cash or in-kind. In-kind payment means payment will be made in portfolio securities rather than cash, and may potentially include illiquid investments. Illiquid investments may not be able to be sold quickly or at a price that reflects full value, or there may not be a market for such investments, which could cause the redeeming shareholder to realize losses on the investment if it is sold at a price lower than that at which it had been valued. If the Fund makes an in-kind payment, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash, whereas such costs are borne by the Fund for cash redemptions. Redemptions in-kind are taxable for federal income tax purposes in the same manner as redemptions for cash and subsequent sale of securities received in-kind may result in taxable gains for federal income tax purposes.
While the Fund may pay redemptions in-kind, the Fund may instead choose to raise cash to meet redemption requests through the sale of fund securities or permissible borrowings. If the Fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the Fund’s NAV and may increase brokerage costs and accelerate the recognition of taxable income.
Suspension of Redemptions
In the event the Fund’s market-based net asset value per share has deviated from the Fund’s amortized cost price per share, or the Fund’s Trustees, including a majority of Independent Trustees, determines that such a deviation is likely to occur, then the Trustees will take such action as they deem appropriate including, but not limited to, suspending redemptions and the payment of redemption proceeds, in order to facilitate the liquidation of the Fund. In addition, if the Fund’s weekly liquid assets fall below 10%, the Fund may cease honoring redemptions and liquidate at the discretion of the Trustees. Prior to suspending redemptions, the Fund would be required to notify the SEC of its decision to suspend redemptions and liquidate. If the Fund ceases honoring redemptions and makes a decision to liquidate, the Fund expects that it would notify shareholders on the Fund’s websites or by press release.
Systematic Withdrawal Plan
You may arrange for periodic redemptions by authorizing your financial intermediary to redeem a specified amount from your account on a day or days you specify. Not all financial intermediaries offer this plan. Contact your financial intermediary for details.
Information on liquidity fees
Pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended, the Fund may impose a discretionary liquidity fee (not to exceed 2% of the value of the Shares redeemed) on redemptions from the Fund. The Trustees have determined to delegate responsibility for administering any discretionary liquidity fee to the Adviser, subject to Board guidelines and oversight.
Liquidity fees are most likely to be imposed during times of extraordinary market stress. Additionally, the Fund will typically notify financial intermediaries and shareholders if a liquidity fee will be imposed (generally, as of the beginning of the next business day following the announcement that the Fund will impose a liquidity fee).
Liquidity fees payable by shareholders of the Fund may be used to offset any losses realized by the Fund when seeking to honor redemption requests during times of extraordinary market stress.
Liquidity fees would reduce the amount you receive upon redemption of your Shares. The Fund retains the liquidity fees for the benefit of remaining shareholders. The imposition of liquidity fees may also affect the check writing privileges for shareholders of the Fund, as discussed below.
20 | Janus Investment Fund

For more information on liquidity fees, please see “Liquidity Fees” in the SAI.
Availability of Portfolio Holdings Information
The Mutual Fund Holdings Disclosure Policies and Procedures adopted by the Adviser and all mutual funds managed within the Janus Henderson fund complex are designed to be in the best interests of the funds and to protect the confidentiality of the funds’ portfolio holdings. The following describes such policies and procedures with respect to disclosure of portfolio holdings.
Full Holdings.The Fund is required to disclose its complete holdings in the annual and semiannual financial statements located in Form N-CSR. In addition, the Fund is required to disclose its complete holdings in a monthly report on Form N-MFP within 5 business days after each month end. Form N-CSR filings and Form N-MFP reports (i) are available on the SEC’s website at http://www.sec.gov and (ii) are available without charge, upon request, by calling a Janus Henderson representative at 1-877-335-2687 (toll free). Holdings are generally posted within 5 business days after each month end under Full Holdings for the Fund at janushenderson.com/info.
Top Holdings.The Fund’s top portfolio holdings, in order of position size and as a percentage of the Fund’s total portfolio, are available monthly with a 15-day lag.
Other Information.The Fund may occasionally provide security breakdowns (e.g., industry, sector, regional, market capitalization, and asset allocation) and specific portfolio level performance attribution information and statistics monthly with a 15-day lag.
Full portfolio holdings will be available monthly and will remain on the Janus Henderson websites for at least 6 months on a rolling basis and will link to the Fund’s Form N-MFP filing available on the SEC website. Under extraordinary circumstances, exceptions to the Mutual Fund Holdings Disclosure Policies and Procedures may be made by the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer or a delegate. Such exceptions may be made without prior notice to shareholders. A summary of the Fund’s portfolio holdings disclosure policies and procedures, which includes a discussion of any exceptions, is contained in the Fund’s SAI.
Shareholder communications
Statements and Reports
Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.
Your financial intermediary or plan sponsor is responsible for providing annual and semiannual reports of the Fund. Please contact your financial intermediary or plan sponsor to obtain these reports. The Fund’s fiscal year ends June 30.
Lost (Unclaimed/Abandoned) Accounts
It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a mutual fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your mutual fund account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Glossary of investment terms
This glossary provides a more detailed description of some of the types of securities, investment strategies, and other instruments in which the Fund may invest, as well as some general investment terms. The Fund may invest in these instruments to the extent permitted by its investment objective and policies. The Fund is not limited by this discussion and may invest in any other types of instruments not precluded by the policies discussed elsewhere in this Prospectus.
Equity and Debt Securities
Agency discount notes are U.S. Government securities that are issued by a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest.
Bonds are debt securities issued by a company, municipality, government, or government agency. The issuer of a bond is required to pay the holder the amount of the loan (or par value of the bond) at a specified maturity and to make scheduled interest payments.
Commercial paper is a short-term debt obligation with a maturity ranging from 1 to 270 days issued by banks, corporations, and other borrowers to finance short-term credit needs. The Fund may purchase commercial paper issued in private placements under Section 4(2) of the Securities Act of 1933, as amended.
Debt securities are securities representing money borrowed that must be repaid at a later date. Such securities have specific maturities and usually a specific rate of interest or an original purchase discount.
Fixed-income securities are securities that pay a specified rate of return. The term generally includes short-and long-term government, corporate, and municipal obligations that pay a specified rate of interest, dividends, or coupons for a specified period of time. Coupon and dividend rates may be fixed for the life of the issue or, in the case of adjustable and floating rate securities, for a shorter period.
Mortgage- and asset-backed securities are shares in a pool of mortgages or other debt instruments. These securities are generally pass-through securities, which means that principal and interest payments on the underlying securities (less servicing fees) are passed through to shareholders on a pro rata basis.
U.S. Government securities include direct obligations of the U.S. Government that are supported by its full faith and credit. Treasury bills have initial maturities of less than one year, Treasury notes have initial maturities of one to ten years, and Treasury bonds may be issued with any maturity but generally have maturities of at least ten years. U.S. Government securities also include indirect obligations of the U.S. Government that are issued by federal agencies and government sponsored entities. Unlike Treasury securities, agency securities generally are not backed by the full faith and credit of the U.S. Government. Some agency securities are supported by the right of the issuer to borrow from the Treasury, others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, and others are supported only by the credit of the sponsoring agency.
Variable amount master demand notes are demand obligations that permit the investment of fluctuating amounts at varying market rates of interest pursuant to arrangements between the issuer and a commercial bank acting as agent for the payee of such notes whereby both parties have the right to vary the amount of the outstanding indebtedness on the notes. These notes are direct lending arrangements between the lender and borrower and there is no secondary market for them. The principal plus accrued interest is redeemable at any time, however. This right to redeem the notes depends on the ability of the borrower to make the specified payments on demand.
Variable and floating rate securities have variable or floating rates of interest and, under certain limited circumstances, may have varying principal amounts. Variable and floating rate securities pay interest at rates that are adjusted periodically according to a specified formula, usually with reference to some interest rate index or market interest rate. The floating rate tends to decrease the security’s price sensitivity to changes in interest rates.
Other Investments, Strategies, and/or Techniques
Repurchase agreements involve the purchase of a security by the Fund and a simultaneous agreement by the seller (generally a bank or dealer) to repurchase the security from the Fund at a specified date or upon demand. This technique offers a method of earning income on idle cash.
