*Before you invest, you may want to review the Fund's prospectus, which, as supplemented, contains more information about the Fund and its risks. You can find the Fund's prospectus, reports to shareholders and other information about the Fund online at* http://investments.pimco.com/prospectuses*. You can also get this information at no cost by calling 888.87.PIMCO or by sending an email request to piprocess@sscinc.com. The Fund's prospectus and Statement of Additional Information, both dated August 1, 2025, as supplemented, are incorporated by reference into this Summary Prospectus.*

**Investment Objective**

The Fund seeks maximum total return, consistent with prudent investment management.

**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. **You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.** 

---

| | |
|:---|:---|
| **Shareholder Fees (fees paid directly from your investment):** | **None** |

---

**Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):** 

---

| | |
|:---|:---|
|  | **Inst**<br> **Class**<br>|
| Management Fees | 0.94% |
| Acquired Fund Fees and Expenses<sup>(1)</sup> <br>| 1.30% |
| **Total Annual Fund Operating Expenses** | **2.24%** |
| Fee Waiver and/or Expense Reimbursement<sup>(2)</sup> <br>| (0.84%) |
| **Total Annual Fund Operating Expenses After Fee Waiver and/or Expense** <br> **Reimbursement**<sup>(3)</sup> <br>| **1.40%** |

---

Acquired Fund Fees and Expenses include interest expense of the Underlying PIMCO Funds of 0.46%. Interest expense can result from certain transactions within the Underlying PIMCO Funds and is separate from the management fees paid to PIMCO. Excluding interest expense of the Underlying PIMCO Funds, Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement are 0.94% for Institutional Class.

PIMCO has contractually agreed, through July 31, 2026, to waive, first, the advisory fee and, second, the supervisory and administrative fee it receives from the Fund in an amount equal to the expenses attributable to the Management Fees of Underlying PIMCO Funds indirectly incurred by the Fund in connection with its investments in Underlying PIMCO Funds up to a maximum waived amount that is equal to the Fund's aggregate advisory fee and supervisory and administrative fee. This waiver renews annually for a full year unless terminated by PIMCO upon at least 30 days' notice prior to the end of the contract term.

Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement do not match the Ratio of Expenses to Average Net Assets of the Fund, as set forth in the Financial Highlights table of the Fund's prospectus, because the Ratio of Expenses to Average Net Assets reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

**Example.** The Example is intended to help you compare the cost of investing in Institutional Class shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the noted class of shares for the time periods indicated, and then hold or redeem all your shares at the end of those periods. 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** |
| Institutional Class | $143 | $620 | $1123 | $2509 |

---

**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 66% of the average value of its portfolio.

**Principal Investment Strategies**

The Fund is designed to provide dynamic exposure to a broad range of emerging market fixed income asset classes, such as external debt obligations of sovereign, quasi-sovereign, and corporate entities; currencies, and local currency-denominated obligations of sovereigns, quasi-sovereigns, and corporate issuers. PIMCO uses a three-step active management approach in seeking to achieve the Fund's investment objective: 1) develop a target asset allocation to implement across the eligible investments; 2) identify additional opportunities for country and security selection designed to add value beyond the target asset allocation within each of the eligible investments; and 3) employ additional investment strategies designed to either mitigate or emphasize risks resulting from the implementation of the target asset allocation. This active management approach is driven by PIMCO's global macroeconomic views, emerging markets expertise and experience across a wide range of investment instruments. The Fund's assets are allocated in a manner that reflects PIMCO's views regarding the attractiveness of key investment risk factors, considering both return potential and volatility, and includes an assessment of aggregate country, issuer and currency exposures.

PIMCO evaluates these three steps daily and uses varying combinations of Acquired Funds (defined below) and/or direct investments in efforts to achieve the most efficient execution of PIMCO's investment views. Specifically, "Acquired Funds" refers to the following: funds of the Trust and funds of PIMCO Equity Series and PIMCO ETF Trust, affiliated open-end investment companies, except funds of funds and PIMCO California Municipal Intermediate Value Fund, PIMCO California Municipal Opportunistic Value Fund, PIMCO National Municipal Intermediate Value Fund and PIMCO National Municipal Opportunistic Value Fund ("Underlying PIMCO Funds") and other affiliated and unaffiliated funds in which the Fund may invest. The term "fund of

------

PIMCO Funds \| **Summary Prospectus**

![](g185639img2e3ca0b01.gif)

------

PIMCO Emerging Markets Full Spectrum Bond Fund

------

funds" refers to mutual funds that pursue their investment objective by investing all or a significant portion of their assets in other funds. Acquired Funds may or may not be registered under the Investment Company Act of 1940 (the "1940 Act"). To the extent Underlying PIMCO Funds of the Trust or PIMCO Equity Series are held, Institutional Class or Class M shares will be held. The Fund's investments may also include Fixed Income Instruments of varying maturities, forwards or derivatives, such as options, futures contracts or swap agreements. "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 will invest in such funds, securities, instruments and other investments to the extent permitted under the 1940 Act, or any exemptive relief therefrom. To the extent the Fund invests in Underlying PIMCO Funds, PIMCO expects to select such Underlying PIMCO Funds without considering or canvassing the universe of available unaffiliated Acquired Funds.

The Fund invests under normal circumstances at least 80% of its assets in investments economically tied to emerging market countries and 80% of its assets in Fixed Income Instruments, which may be represented by direct or indirect (through an Acquired Fund) investments. The Fund may invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. In addition, the Fund may invest in both investment-grade securities and high yield securities ("junk bonds") rated at least Caa by Moody's Ratings ("Moody's"), or equivalently rated by Standard & Poor's Rating Services ("S&P") or Fitch Ratings, Inc. ("Fitch"), or, if unrated, determined by PIMCO to be of comparable quality. 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's benchmark index is a blend of 50% JPMorgan Global Bond Index Emerging Markets-Global Diversified, 25% JPMorgan Emerging Markets Bond Index Global and 25% JPMorgan Corporate Emerging Market Bond Index Diversified (the "Benchmark"). The Fund will normally limit its net foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to between 20% and 80% of its assets. The average portfolio duration of this Fund normally varies within two years (plus or minus) of the portfolio duration of the securities comprising the Benchmark, as calculated by PIMCO, which as of May 31, 2025 was 5.22 years. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

The Fund's assets are not allocated according to a predetermined blend of investment exposures or mix of instruments. PIMCO has the flexibility to reallocate the Fund's assets among any or all of the investment exposures represented by affiliated or unaffiliated funds, or invest directly in securities, instruments and other investments, based on its ongoing analyses of the global economy and financial markets. While these analyses are performed daily, material shifts in investment exposures typically take place over longer periods of time, unless in response to a perceived short-term opportunity or market dislocation. The "total return" sought by the Fund consists of income earned on the

Fund's investments, plus capital appreciation, if any, which generally arises from decreases in interest rates, foreign currency appreciation, or improving credit fundamentals for a particular sector or security.

Additional information for the Underlying PIMCO Funds can be found in the Statement of Additional Information and/ or the Underlying PIMCO Funds' prospectuses and financial reports. Additional Underlying PIMCO Funds may be added or deleted in the future without shareholder notification.

**Principal Risks**

It is possible to lose money on an investment in the Fund. The principal risks of investing in the Fund include risks from direct investments and/or indirect exposure through investment in Acquired Funds. The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return, are listed below.

The following risks are principal risks of investing in the Fund.

**Allocation Risk:** the risk that the Fund could experience losses as a result of less than optimal or poor asset allocation decisions. The Fund could miss attractive investment opportunities by underweighting markets that subsequently experience significant returns and could lose value by overweighting markets that subsequently experience significant declines

**Acquired Fund Risk:** the risk that the Fund's performance is closely related to the risks associated with the securities and other investments held by the Acquired Funds and that the ability of the Fund to achieve its investment objective will depend upon the ability of the Acquired Funds to achieve their investment objectives. Investments in Acquired Funds that are exchange-traded funds are also subject to market risk, tracking error, the potential for trading at a discount or premium to their net asset value, bid/ask spread risk as well as the risks of the underlying securities they hold. In addition, the Fund's performance will be reduced by the Fund's proportionate amount of the expenses of any Acquired Funds in which it invests

The following are principal risks of investing in the Fund that include risks from direct investments and/or indirect exposure through investment in Acquired Funds.

**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. Factors such as government policy, inflation, the economy, and market for bonds can impact interest rates and yields

**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 including 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 experience losses 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 market, credit, call and liquidity risks. High yield securities are considered primarily speculative by rating agencies with respect to the issuer's continuing ability to make principal and interest payments, and their values may be more volatile than higher-rated securities of similar maturity

**Distressed Company Risk:** the risk that securities of distressed companies may be subject to greater levels of market, credit, issuer and liquidity risks. Distressed companies may be engaged in restructurings or bankruptcy proceedings, which may cause the value of their securities to fluctuate rapidly or unpredictably

**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 reasons 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 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, options, 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

**Commodity Risk:** the risk that investing in commodity-linked derivative instruments and commodities, either directly or indirectly through a subsidiary, may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments or commodities may be affected by changes in overall market movements, foreign currency exchange rates, commodity index volatility, changes in inflation, interest rates, or supply and demand factors affecting a particular industry or commodity market, such as drought, floods, weather, livestock disease, pandemics and public health emergencies, embargoes, taxation, war, terrorism, cyber hacking, economic and political developments, environmental proceedings, tariffs, changes in storage costs, availability of transportation systems, and international economic, political and regulatory developments. Investments in commodities can also present risks associated with transportation and delivery, custody, storage and maintenance, illiquidity, and the unavailability of accurate market valuations of the commodity

**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 and other asset-backed securities, including junior and/or equity tranches (to the extent consistent with the Fund's guidelines), which generally carry higher levels of the foregoing risks

**Foreign (Non-U.S.) Investment Risk:** the risk that investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing

------

August 1, 2025 \| **SUMMARY PROSPECTUS** 3

reporting, accounting, corporate governance and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable U.S. or foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, political changes, diplomatic developments, trade restrictions (including tariffs) or the imposition of sanctions and other similar measures. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuers

**Real Estate Risk:** the risk that the Fund's investments in real estate investment trusts ("REITs") or real estate-linked derivative instruments will subject the Fund to risks similar to those associated with direct ownership of real estate, including risks related to losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses. The Fund's investments in REITs or real estate-linked derivative instruments subject it to management and tax risks. In addition, REITs that are privately held or not traded on a national securities exchange may subject the Fund to liquidity and valuation risk

**Emerging Markets Risk:** the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk

**Sovereign Debt Risk:** the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer's inability or unwillingness to make principal or interest payments in a timely fashion

**Currency Risk:** the risk that foreign (non-U.S.) currencies will change in value relative to the U.S. dollar and affect the Fund's investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies

**Smaller Company Risk:** the risk that the value of securities issued by a smaller company may go up or down, sometimes rapidly and unpredictably as compared to more widely held securities, due to narrow markets and limited resources of smaller companies. Investments in smaller companies generally are subject to greater levels of credit, market and issuer risk

**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. The use of leverage may also increase the Fund's sensitivity to interest rate risks

**Management Risk:** the risk that the investment techniques and risk analyses applied by PIMCO, including the use of quantitative models or methods, 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

**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

**Tax Risk:** the risk that the tax treatment of swap agreements and other derivative instruments, such as commodity-linked derivative instruments, including commodity index-linked notes, swap agreements, commodity options, futures, and options on futures, may be affected by future regulatory or legislative changes that could affect whether income from such investments is "qualifying income" under Subchapter M of the Internal Revenue Code, or otherwise affect the character, timing and/or amount of the Fund's taxable income or gains and distributions

**Subsidiary Risk:** the risk that, by investing in certain Underlying PIMCO Funds that invest in a subsidiary (each a "Subsidiary"), the Fund is indirectly exposed to the risks associated with a Subsidiary's investments. The Subsidiaries are not registered under the 1940 Act and may not be subject to all the investor protections of the 1940 Act. There is no guarantee that the investment objective of a Subsidiary will be achieved

**Value Investing Risk:** a value stock may decrease in price or may not increase in price as anticipated by PIMCO if it continues to be undervalued by the market or the factors that the portfolio manager believes will cause the stock price to increase do not occur

**Arbitrage Risk:** the risk that securities purchased pursuant to an arbitrage strategy intended to take advantage of a perceived relationship between the value of two securities may not perform as expected. In addition, disruptions in market conditions or limitations on the Fund's ability to access certain markets or securities may reduce the effectiveness of arbitrage strategies

**Convertible Securities Risk:** as convertible securities share both fixed income and equity characteristics, they are subject to risks to which fixed income and equity investments are subject. These risks include equity risk, interest rate risk and credit risk

**Exchange-Traded Fund Risk:** the risk that an exchange-traded fund may not achieve its investment objective, among other reasons, because of regulatory restrictions, including, for example, exchange rules, market prices of shares of an exchange-traded fund may fluctuate rapidly and materially, or shares of an exchange-traded fund may trade significantly above or below net asset value, any of which may cause losses to the Fund invested in the exchange-traded 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 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. The Fund's regulatory index is the Bloomberg Global Aggregate (USD Hedged) Index. The Fund's regulatory index is shown in connection with certain regulatory requirements to provide a broad measure of market performance. The Bloomberg Global Aggregate (USD Hedged) Index provides a broad-based measure of the global investment-grade fixed income markets. The three major components of this index are the U.S. Aggregate, the Pan-European Aggregate, and the Asian-Pacific Aggregate Indices. The index also includes Eurodollar and Euro-Yen corporate bonds, Canadian Government securities, and USD investment grade 144A securities. The supplemental index shown is a blend of 50% J.P. Morgan Global Bond Index Emerging Markets- Global Diversified, 25% J.P. Morgan Emerging Markets Bond Index Global and 25% J.P. Morgan Corporate Emerging Market Bond Index Diversified. The J.P. Morgan Global Bond Index Emerging Markets - Global Diversified is a uniquely-weighted version of the Emerging Markets Bond Index Global. It limits the weights of those index countries with larger debt stocks by only including specified portions of these countries' eligible current face amounts of debt outstanding. The J.P. Morgan Emerging Markets Bond Index Global tracks total returns for U.S. dollar-denominated debt instruments issued by emerging market sovereign and quasi-sovereign entities: Brady bonds, loans, and Eurobonds. J.P. Morgan Corporate Emerging Market Bond Index Diversified tracks total returns of U.S. dollar-denominated debt instruments issued by corporate entities in Emerging Markets countries.

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 <u>https://www.pimco.com/en-us/product-finder</u>.

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.
