Investment objective

Franklin U.S. Low Volatility High Dividend Index ETF (“Low Volatility High Dividend Index ETF” or the “fund”) seeks to track the investment results of an index composed of equity securities of U.S. companies with relatively high yield and low price and earnings volatility.

Fees and expenses of the fund

The accompanying table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may also be subject to additional fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. The management agreement between Legg Mason ETF Investment Trust (the “Trust”) and Legg Mason Partners Fund Advisor, LLC (“LMPFA” or the “manager”) (the “Management Agreement”) provides that the manager will pay all operating expenses of the fund, except interest expenses, taxes, brokerage expenses, future Rule 12b-1 fees (if any), acquired fund fees and expenses, extraordinary expenses and the management fee payable to the manager under the Management Agreement. The manager will also pay all subadvisory fees of the fund.

Example:

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. The example assumes:

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the example.

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 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 52% of the average value of its portfolio.

Principal investment strategies

The fund seeks to track the investment results of the QS Low Volatility High Dividend Index (the “Underlying Index”). The Underlying Index seeks to provide more stable income through investments in stocks of profitable U.S. companies with relatively high dividend yields and lower price and earnings volatility. The Underlying Index is based on a proprietary methodology created and sponsored by Franklin Advisers, Inc. (“Franklin Advisers”), the fund’s subadviser. Franklin Advisers is affiliated with both LMPFA and the fund. The Underlying Index is composed of stocks of U.S. companies across a wide range of market capitalizations, including the largest 3,000 U.S. stocks as determined by the Solactive US Broad Market Index. Stocks in the Underlying Index must have demonstrated profitability over the last four fiscal quarters as a whole. Stocks whose yields are not supported by earnings are excluded from the Underlying Index. The methodology calculates a composite “stable yield” score, with the yield of stocks with relatively higher price volatility and earnings volatility adjusted downward and the yield of stocks with relatively lower price volatility and earnings volatility adjusted upward. Franklin Advisers anticipates that the number of component securities in the Underlying Index will range from 50 to 100. At the time of each reconstitution, no individual component of the Underlying Index will exceed 2.5% of the Underlying Index, no individual sector will exceed 25% of the Underlying Index, and real estate investment trust (“REIT”) components as a whole will not exceed 15% of the Underlying Index. The Underlying Index’s components are reconstituted annually and rebalanced quarterly. The composition of the Underlying Index and the fund after reconstitution and rebalancing may fluctuate and exceed the above Underlying Index limitations due to market movements. The Underlying Index may include large-, mid- or small-capitalization companies.

The fund’s portfolio is rebalanced when the Underlying Index is rebalanced or reconstituted. The fund may trade at times other than when the Underlying Index is rebalanced or reconstituted for a variety of reasons, including when adjustments may be made to its representative sampling process from time to time or when investing cash.

The fund will invest at least 80% of its net assets, plus borrowings for investment purposes, if any, in securities that compose the Underlying Index.

The fund may invest up to 20% of its net assets in certain index futures, options, options on index futures, swap contracts or other derivatives (“Financial Instruments”) related to its Underlying Index and its component securities; cash and cash equivalents; other investment

companies, including exchange-traded funds; and in securities and other instruments not included in its Underlying Index but which Franklin Advisers believes will help the fund track its Underlying Index. The fund may invest in exchange-traded equity index futures to manage sector exposure and for cash management purposes.

Index investing. The fund uses a “passive” or indexing investment approach to achieve its investment objective. Unlike many investment companies, the fund does not try to outperform its Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued. Indexing may eliminate the chance that the fund will substantially outperform the Underlying Index and also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

The subadviser may use a representative sampling indexing strategy to manage the fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of the Underlying Index. When representative sampling is used, the securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as return variability, risk, market capitalization, country/region exposures and sector exposures) and fundamental characteristics (such as portfolio yield, price/earnings ratios and price/book ratios) similar to those of the Underlying Index. The fund may or may not hold all of the securities in the Underlying Index.

Industry concentration policy. The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry to approximately the same extent that the Underlying Index is concentrated in the securities of such particular industry. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

As of March 31, 2023, the top sector represented by the fund’s Underlying Index was the utilities sector. This sector may change over time.

Principal risks

Risk is inherent in all investing. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or by any bank or government agency. The following is a list of the principal risks of investing in the fund. The descriptions appear in alphabetical order, not order of importance.

Asset class risk. Securities or other assets in the Underlying Index or in the fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Authorized Participant concentration risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the fund. “Authorized Participants” are broker-dealers that are permitted to create and redeem shares directly with the fund and who have entered into agreements with the fund’s distributor. A limited number of institutions act as Authorized Participants in respect of the fund. To the extent that these institutions exit the business or are unable to process creation and/or redemption orders with respect to the fund and no other Authorized Participant steps forward to create or redeem, in either of these cases, fund shares may trade at a premium or discount to net asset value and possibly face trading halts and/or delisting.

Calculation methodology risk. The Underlying Index relies on various sources of information to assess the criteria of issuers, including information that may be based on assumptions and estimates. The fund, LMPFA and the subadviser do not guarantee the accuracy of the Underlying Index or have liability for any errors therein.

Concentration risk. The fund will be susceptible to an increased risk of loss, including losses due to events that adversely affect the fund’s investments more than the market as a whole, to the extent that the fund’s investments are concentrated in the securities of a particular issuer or issuers within the same geographic region, market, industry, group of industries, sector or asset class.

Cybersecurity risk. Cybersecurity incidents, whether intentionally caused by third parties or otherwise, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information) or proprietary information, cause the fund, the manager, the subadvisers, Authorized Participants, the relevant listing exchange and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. The fund, the manager, and the subadvisers have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund, the manager, and/or the subadvisers. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the fund’s ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the fund, the manager, the subadvisers, Authorized Participants, the relevant listing exchange and their service providers are subject to the risk of cyber incidents occurring from time to time.

Derivatives risk. Using derivatives can increase fund losses and reduce opportunities for gains, such as when market prices, interest rates, currencies, or the derivatives themselves, behave in

a way not anticipated by the fund’s subadviser. Using derivatives also can have a leveraging effect and increase fund volatility. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivatives may not be available at the time or price desired, may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the fund. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. The value of a derivative may fluctuate more than the underlying assets, rates, indices or other indicators to which it relates. Use of derivatives may have different tax consequences for the fund than an investment in the underlying asset, and those differences may affect the amount, timing and character of income distributed to shareholders. The U.S. government and foreign governments have adopted and implemented or are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.

Dividend-paying stock risk. There is no guarantee that the issuers of the stocks held by the fund will pay dividends in the future or that, if dividends are paid, they will remain at their current levels or increase over time. The fund’s emphasis on dividend-paying stocks could cause the fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends or ability to pay dividends in the future. Dividend-paying stocks may not participate in a broad market advance to the same degree as other stocks, and a sharp rise in interest rates or economic downturn or other market or company-specific developments could cause a company to reduce or eliminate its dividend.

Illiquidity risk. Some assets held by the fund may be or become impossible or difficult to sell and some assets that the fund wants to invest in may be impossible or difficult to purchase, particularly during times of market turmoil or due to adverse changes in the conditions of a particular issuer. These illiquid assets may also be difficult to value. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, or to try to limit losses, the fund may be forced to sell at a substantial loss or may not be able to sell at all. The fund may not receive its proceeds from the sale of certain securities for an extended period (for example, several weeks or even longer).

Index-related risk. There is no guarantee that the fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index administrator for a period of time or at all, which may have an adverse impact on the fund and its shareholders.

Index sampling risk. The fund may not fully replicate its Underlying Index (including for operational reasons or due to costs of access to a market) and may hold securities not included in the Underlying Index. As a result, the fund is subject to the risk that Franklin Advisers’ investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Issuer risk. The market price of a security can go up or down more than the market as a whole and can perform differently from the value of the market as a whole, due to factors specifically relating to the security’s issuer, such as disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, changes in management, corporate actions, negative perception in the marketplace, or major litigation or changes in government regulations affecting the issuer or the competitive environment. An individual security may also be affected by factors relating to the industry or sector of the issuer. The fund may experience a substantial or complete loss on an individual security. A change in financial condition or other event affecting a single issuer may adversely impact the industry or sector of the issuer or securities markets as a whole.

Large capitalization company risk. Large capitalization companies may fall out of favor with investors based on market and economic conditions. In addition, larger companies may not be able to attain the high growth rates of successful smaller companies and may be less capable of responding quickly to competitive challenges and industry changes. As a result, the fund’s value may not rise as much as, or may fall more than, the value of funds that focus on companies with smaller market capitalizations.

Market events risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, wars, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries or markets directly affected, the value and liquidity of the fund’s investments may be negatively affected. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the fund’s investments.

The fallout from the COVID-19 pandemic and its subsequent variants, and the long-term impact on economies, markets, industries and individual issuers, are not known. Some sectors of the

economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets; reduced liquidity of many instruments; and disruptions to supply chains, consumer demand and employee availability, may continue for some time. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, have taken extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic. This and other government intervention into the economy and financial markets may not work as intended, and have resulted in a large expansion of government deficits and debt, the long term consequences of which are not known. In addition, the COVID-19 pandemic, and measures taken to mitigate its effects, could result in disruptions to the services provided to the fund by its service providers.

Market trading risk. The fund faces numerous market trading risks, including the potential lack of an active market for fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Any of these factors, among others, may lead to the fund’s shares trading at a premium or discount to net asset value.

Absence of active market. Although shares of the fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants. Authorized Participants are not obligated to execute purchase or redemption orders for Creation Units. In periods of market volatility, market makers and/or Authorized Participants may be less willing to transact in fund shares. The absence of an active market for the fund’s shares may contribute to the fund’s shares trading at a premium or discount to net asset value.

Shares of the fund may trade at prices other than net asset value. Shares of the fund trade on stock exchanges at prices at, above or below the fund’s most recent net asset value. The net asset value of the fund is calculated at the end of each business day and fluctuates with changes in the market value of the fund’s holdings. The trading price of the fund’s shares fluctuates continuously throughout trading hours based on both market supply of and demand for fund shares and the underlying value of the fund’s portfolio holdings or net asset value. As a result, the trading prices of the fund’s shares may deviate significantly from net asset value during periods of market volatility, including during periods of high redemption requests or other unusual market conditions. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NET ASSET VALUE.

Passive investment risk. The fund is not actively managed and neither LMPFA nor the subadviser attempts to take defensive positions.

REITs risk. The value of real estate investment trusts (“REITs”) may be affected by factors including the condition of the economy as a whole, changes in the value of the underlying real estate, the creditworthiness of the issuers of the investments, property taxes, interest rates, liquidity of the credit markets, poor performance by the REIT’s manager, and the real estate regulatory environment. REITs that concentrate their holdings in specific businesses, such as apartments, offices or retail space, will be affected by conditions affecting those businesses.

Small and mid-capitalization company risk. The fund will be exposed to additional risks as a result of its investments in the securities of small and mid-capitalization companies. Small and

mid-capitalization companies may fall out of favor with investors; may have limited product lines, operating histories, markets or financial resources; or may be dependent upon a limited management group. The prices of securities of small and mid-capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession. Securities of small and mid-capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may have greater potential for losses.

Stock market and equity securities risk. The stock markets are volatile and the market prices of the fund’s equity securities may decline generally. Equity securities may include warrants, rights, exchange-traded and over-the-counter common stocks, preferred stock, depositary receipts, trust certificates, limited partnership interests and shares of other investment companies, including exchange-traded funds and real estate investment trusts. Equity securities may have greater price volatility than other asset classes, such as fixed income securities, and may fluctuate in price based on actual or perceived changes in a company’s financial condition and overall market and economic conditions and perceptions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline.

Tracking error risk. The fund may be subject to tracking error, which is the divergence of the fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs, the fund’s holding of uninvested cash, differences in timing of the accrual of distributions, the requirements associated with tax treatment as a regulated investment company, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, changes to the Underlying Index or the need to meet various new or existing regulatory requirements. In addition, certain regulatory or contractual requirements applicable to the fund’s use of derivatives could prevent the fund from being able to fully replicate the hedge impact incorporated in the calculation of the Underlying Index, which could result in increased index tracking error. Tracking error may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the fund incurs fees and expenses, while the Underlying Index does not.

Trading issues risk. Trading in fund shares on NASDAQ may be halted in certain circumstances. There can be no assurance that the requirements of NASDAQ necessary to maintain the listing of the fund will continue to be met.

Utilities sector risk. Investments in energy related utilities companies involve special considerations, including the risk of changing commodity prices, government regulation and oversight, increased tariffs, changes in tax laws, interest rate fluctuations, rising costs of financing capital construction and changes in the cost of providing utility services. The utilities sector is also subject to potential terrorist attacks, natural disasters and severe weather conditions, catastrophic accidents or other events, as well as regulatory and operational burdens associated with the operation and maintenance of facilities.

Valuation risk. The sales price the fund could receive upon the sale of any particular portfolio investment may differ from the fund’s valuation of the investment and may differ from the value used by the Underlying Index, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. These differences may increase significantly and affect fund investments more broadly during periods of market volatility. Authorized Participants who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the fund’s investments involves subjective judgment.

Volatility risk. The market prices of the securities or other assets in the fund’s portfolio may fluctuate, sometimes rapidly and unpredictably. The price of a security may fluctuate due to factors affecting markets generally or particular industries. The market price of a security or other asset may also be more volatile than the market as a whole. This volatility may affect the fund’s net asset value. Although the Underlying Index’s models were created to invest in stocks that exhibit low volatility characteristics, there is no guarantee that these models and strategies will be successful. Securities or other assets 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. Events or financial circumstances affecting individual securities or sectors may increase the volatility of the fund.

These and other risks are discussed in more detail in the Prospectus or in the Statement of Additional Information.

Performance

The accompanying bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the fund’s performance from year to year. The table shows the average annual total returns of the fund and also compares the fund’s performance with the average annual total returns of an index or other benchmark. The fund makes updated performance information, including its current net asset value, available at www.franklintempleton.com/etfproducts (select fund), or by calling the fund at 1-877-721-1926.

The fund’s past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future.

Best Quarter (12/31/2022): 13.51    Worst Quarter (03/31/2020): (24.52)

The year-to-date return as of the most recent calendar quarter, which ended June 30, 2023, was (2.95)

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. Returns after taxes on distributions and sale of fund shares are higher than returns before taxes for certain periods shown because they reflect the tax benefit of capital losses realized on the sale of fund shares.

Management

Investment manager: Legg Mason Partners Fund Advisor, LLC (“LMPFA”)

Subadviser: Franklin Advisers, Inc. (“Franklin Advisers”)

Portfolio managers: Primary responsibility for the day-to-day management of the fund lies with the following portfolio managers.

Purchase and sale of fund shares

The fund is an exchange-traded fund (“ETF”). Individual shares of the fund are listed on a national securities exchange and are redeemable only by Authorized Participants in aggregated blocks of shares or multiples thereof (“Creation Units”).

Individual shares of the fund may only be purchased and sold in the secondary market through a broker-dealer at market prices. Because fund shares trade at market prices rather than at net asset value, fund shares may trade at a price greater than net asset value (a premium) or less than net asset value (a discount).

When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the fund (bid) and the lowest price a seller is willing to accept for shares of the fund (ask) (the “bid-ask spread”).

The fund will only issue or redeem Creation Units to Authorized Participants who have entered into agreements with the fund’s distributor. The fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the fund specifies each day.

You may access recent information, including information on the fund’s net asset value, market price, premiums and discounts, and bid-ask spreads, on the fund’s website at www.franklintempleton.com/etfproducts.

Tax information

The fund’s distributions are generally taxable and will be taxed as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged account, such as a 401(k) plan or an individual retirement account, in which case your distributions may be taxed when withdrawn from such tax-advantaged account.

Payments to broker/dealers and other financial intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), LMPFA or other related companies pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the fund. 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. Ask your salesperson or visit your financial intermediary’s website for more information.
