Portfolio Turnover
The Fund pays transaction costs 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 the Annual Fund Operating Expenses or in the Example tables, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 34% of the average value of its portfolio.
Principal Investment Strategies
The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its assets in debt securities whose interest is, in the opinion of bond counsel for the issuer at the time of issuance, exempt from federal income tax (“Municipal Bonds”). Municipal Bonds generally are issued by or on behalf of states and local governments and their agencies, authorities and other instrumentalities.
The Fund intends to invest a portion of its assets in high yield Municipal Bonds and “private activity” bonds that are rated (at the time of purchase) below investment grade by Moody’s Investors Service, Inc. (“Moody’s”), or equivalently rated by Standard & Poor’s Ratings Services (“S&P”) or Fitch Ratings, Inc. (“Fitch”), or, if unrated, determined by PIMCO to be of comparable quality (commonly known as “junk
PIMCO Funds | Summary Prospectus
 
PIMCO High Yield Municipal Bond Fund
bonds”). In the event that ratings services assign different ratings to the same security, PIMCO will use the highest rating as the credit rating for that security. The Fund may also invest, without limitation, in higher rated Municipal Bonds. The Fund may invest up to 30% of its assets in “private activity” bonds whose interest is a tax-preference item for purposes of the federal alternative minimum tax (“AMT”). For shareholders subject to the AMT, distributions derived from “private activity” bonds must be included in their AMT calculations, and as such a portion of the Fund’s distribution may be subject to federal income tax. The Fund may invest more than 25% of its total assets in bonds of issuers in California and New York. To the extent that the Fund concentrates its investments in California or New York, it will be subject to the applicable state-specific risk. The Fund may also invest in Municipal Bonds issued by Puerto Rico or its instrumentalities. The Fund may also invest 25% or more of its total assets in Municipal Bonds that finance education, health care, housing, transportation, utilities and other similar projects, and 25% or more of its total assets in industrial development bonds.
The average portfolio duration of this Fund normally varies within (negative) 2 years to positive 4 years of the portfolio duration of the securities comprising the Bloomberg High Yield Municipal Bond Index, as calculated by PIMCO, which as of May 31, 2024 was 6.91 years. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. The portfolio manager focuses on Municipal Bonds with the potential to offer high current income, typically looking for Municipal Bonds that can provide consistently attractive current yields or that are trading at competitive market prices. The “total return” sought by the Fund consists of both income earned on its investments and capital appreciation, if any, generally arising from decreases in interest rates or improving credit fundamentals for a particular state, municipality or issuer.
The Fund may invest in other types of Fixed Income Instruments. “Fixed Income Instruments” include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The Fund may also invest in derivative instruments, such as options, futures contracts or swap agreements, and invest in mortgage- or asset-backed securities. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. In addition, the Fund may also invest in securities issued by entities, such as trusts, whose underlying assets are Municipal Bonds, including, without limitation, residual interest bonds. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls). The Fund may also invest up to 10% of its total assets in preferred securities.
Principal Risks
It is possible to lose money on an investment in the Fund. The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return, are listed below.
Interest Rate Risk: the risk that fixed income securities will fluctuate in value because of a change in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration
Call Risk: the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security that the Fund has invested in, the Fund may not recoup the full amount of its initial investment or may not realize the full anticipated earnings from the investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features
Credit Risk: the risk that the Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivative contract, or the issuer or guarantor of collateral, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations
High Yield Risk: the risk that high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”) are subject to greater levels of credit, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer’s continuing ability to make principal and interest payments, and may be more volatile than higher-rated securities of similar maturity
Market Risk: the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industries
Issuer Risk: the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, changes in financial condition or credit rating, financial leverage, reputation or reduced demand for the issuer’s goods or services
Liquidity Risk: the risk that a particular investment may be difficult to purchase or sell and that the Fund may be unable to sell illiquid investments at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, causing increased supply in the market due to selling activity
Derivatives Risk: the risk of investing in derivative instruments (such as forwards, futures, swaps and structured securities) and other similar investments, including leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative or other similar investment may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or

index, and the Fund could lose more than the initial amount invested. Changes in the value of a derivative or other similar instrument may also create margin delivery or settlement payment obligations for the Fund. The Fund’s use of derivatives or other similar investments may result in losses to the Fund, a reduction in the Fund’s returns and/or increased volatility. Non-centrally-cleared over-the-counter (“OTC”) derivatives or other similar investments are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for non-centrally-cleared OTC derivatives or other similar investments. The primary credit risk on derivatives or other similar investments that are exchange-traded or traded through a central clearing counterparty resides with the Fund's clearing broker or the clearinghouse. Changes in regulation relating to a registered fund’s use of derivatives and related instruments could potentially limit or impact the Fund’s ability to invest in derivatives, limit the Fund’s ability to employ certain strategies that use derivatives or other similar investments and/or adversely affect the value of derivatives or other similar investments and the Fund’s performance
Equity Risk: the risk that the value of equity or equity-related securities, such as common stocks and preferred securities, may decline due to general market conditions which are not specifically related to a particular company or to factors affecting a particular industry or industries. Equity or equity-related securities generally have greater price volatility than fixed income securities. In addition, preferred securities may be subject to greater credit risk or other risks, such as risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rates, regulatory changes and special redemption rights
Mortgage-Related and Other Asset-Backed Securities Risk: the risks of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit risk. The Fund may invest in any tranche of mortgage-related or other asset-backed securities, including junior and/or equity tranches (to the extent consistent with other of the Fund’s guidelines), which generally carry higher levels of the foregoing risks
Leveraging Risk: the risk that certain transactions of the Fund, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss
Management Risk: the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO and the individual portfolio managers in connection with managing the Fund and may cause PIMCO to restrict or
prohibit participation in certain investments. There is no guarantee that the investment objective of the Fund will be achieved
Municipal Bond Risk: the risk that a Fund may be affected significantly by the economic, regulatory or political developments affecting the ability of issuers of Municipal Bonds to pay interest or repay principal
California State-Specific Risk: the risk that by concentrating its investments in California Municipal Bonds, the Fund may be affected significantly by economic, regulatory or political developments affecting the ability of California issuers to pay interest or repay principal
New York State-Specific Risk: the risk that by concentrating its investments in New York Municipal Bonds, the Fund may be affected significantly by economic, regulatory or political developments affecting the ability of New York issuers to pay interest or repay principal
Puerto Rico-Specific Risk:  the risk that by investing in Municipal Bonds issued by Puerto Rico or its instrumentalities, the Fund may be affected by certain developments, such as political, economic, environmental, social, regulatory or debt restructuring developments, that impact the ability or obligation of Puerto Rico municipal issuers to pay interest or repay principal
AMT Bonds Risk: the risk that “AMT Bonds,” which are municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to noncorporate taxpayers, may expose the Fund to certain risks in addition to those typically associated with municipal bonds. Interest or principal on AMT Bonds paid out of current or anticipated revenues from a specific project or specific asset may be adversely impacted by declines in revenue from the project or asset. Declines in general business activity could also affect the economic viability of facilities that are the sole source of revenue to support AMT Bonds. In this regard, AMT Bonds may entail greater risks than general obligation municipal bonds. For shareholders subject to the federal alternative minimum tax, a portion of the Fund’s distributions may not be exempt from gross federal income, which may give rise to alternative minimum tax liability
Municipal Project-Specific Risk: the risk that the Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of similar projects (such as those relating to education, health care, housing, transportation and utilities), industrial development bonds, or in bonds from issuers in a single state
Short Exposure Risk: the risk of entering into short sales or other short positions, including the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale or other short position will not fulfill its contractual obligations, causing a loss to the Fund
Please see “Description of Principal Risks” in the Fund's prospectus for a more detailed description of the risks of investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information
The performance information shows summary performance information for the Fund in a bar chart and an Average Annual Total Returns table. The information provides some indication of the risks of investing in the Fund by showing changes in its performance from year to year and by showing how the Fund’s average annual returns compare with the returns of certain indexes. Absent any applicable fee waivers and/or expense limitations, performance would have been lower. The bar chart shows performance of the Fund’s Institutional Class shares. For periods prior to the inception date of I-3 shares (July 30, 2021), performance information shown in the table for that class is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses paid by the I-3 shares. Performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges.The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.
In addition to the Fund’s performance, the Average Annual Total Returns table includes performance of: (i) a broad-based securities market index (i.e., a regulatory index) and (ii) a supplemental index. It is not possible to invest directly in an unmanaged index. Effective July 24, 2024, the Fund’s regulatory index is the Bloomberg Municipal Bond Index. The Fund’s regulatory index is shown in connection with certain regulatory requirements to provide a broad measure of market performance. The Bloomberg Municipal Bond Index consists of a broad selection of investment-grade general obligation and revenue bonds of maturities ranging from one year to 30 years. It is an unmanaged index representative of the tax-exempt bond market. The index is made up of all investment grade municipal bonds. The supplemental index shown is the Bloomberg High Yield Municipal Bond Index. The Bloomberg High Yield Municipal Bond Index measures the non-investment grade and non-rated U.S. tax-exempt bond market. It is an unmanaged index made up of dollar-denominated, fixed-rate municipal securities that are rated Ba1/BB+/BB+ or below or non-rated and that meet specified maturity, liquidity, and quality requirements. To be included in the Index, bonds must be rated non-investment-grade (Ba1/ BB+/BB+ or below) using the middle rating of the following rating agencies: Moody’s, S&P and Fitch. If only two of the three agencies rate the security, the lower rating is used to determine Index eligibility. If only one of the three agencies rates a security, that rating is used. Non-rated issues are also eligible. Bonds must have an outstanding par value of at least $3 million and must be issued as part of a transaction of at least $20 million. The bonds must be fixed-rate, have a dated-date after January 1, 1991, and must be at least one year from their maturity date. Defaulted securities, remarketed issues, taxable municipal bonds, bonds with floating rates, partially pre-refunded bonds where no new securities are issued, illiquid securities that lack reliable pricing, and private placements are excluded from the benchmark.
Performance for the Fund is updated daily and quarterly and may be obtained as follows: daily and quarterly updates on the net asset value and performance page at https://www.pimco.com/en-us/product-finder.

After-tax returns are calculated using the highest historical 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-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other classes will vary.
Investment Adviser/Portfolio Managers
PIMCO serves as the investment adviser for the Fund. The Fund’s portfolio is jointly and primarily managed by David Hammer and Kyle Christine. Mr. Hammer is a Managing Director of PIMCO, and he has managed the Fund since August 2015. Mr. Christine is a Senior Vice President of PIMCO, and he has managed the Fund since April 2023.
