"Other Expenses" include interest expense of 0.01%. Interest expense is borne by the Fund separately from the management fees paid to Pacific Investment Management Company LLC ("PIMCO"). Excluding interest expense, Total Annual Fund Operating

Expenses After Fee Waiver and/or Expense Reimbursement are 0.95%, 1.05%, 1.40% and 2.15% are Institutional Class, I-2, Class A and Class C shares, respectively.

Total Annual Fund Operating Expenses do not match the Ratio of Expenses to Average Net Assets Excluding Waivers 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 Excluding Waivers reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

PIMCO has contractually agreed to waive the Fund's advisory fee and the supervisory and administrative fee in an amount equal to the management fee and administrative services fee, respectively, paid by the PIMCO Cayman Commodity Fund II Ltd. (the "Subsidiary") to PIMCO. The Subsidiary pays PIMCO a management fee and an administrative services fee at the annual rate of 0.49% and 0.20%, respectively, of its net assets. This waiver may not be terminated by PIMCO and will remain in effect for as long as PIMCO's contract with the Subsidiary is in place.

PIMCO has contractually agreed, through July 31, 2023, 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.

**Example.** The Example is intended to help you compare the cost of investing in Institutional Class, I-2, Class A or Class C 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 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:

**If you redeem your shares at the end of each period:**

| I-2 | $108 | $367 | $646 | $1442 |
| Class A | $686 | $1000 | $1336 | $2282 |
| Class C | $319 | $705 | $1217 | $2625 |

**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 119% of the average value of its portfolio.

PIMCO Global Core Asset Allocation Fund

------

**Principal Investment Strategies**

The Fund is intended for investors who prefer to have their asset allocation decisions made by professional investment managers. Pacific Investment Management Company LLC ("PIMCO") uses a three-step approach in seeking to achieve the Fund's investment objective which consists of 1) developing a target asset allocation; 2) developing a series of relative value strategies designed to add value beyond the target allocation; and 3) utilizing hedging techniques to manage risks. PIMCO evaluates these three steps and uses varying combinations of Acquired Funds and/or direct investments to implement them within the Fund. The Fund may invest in Institutional Class or Class M shares of any funds of the Trust and PIMCO Equity Series, an affiliated open-end investment company, 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 may also invest in other affiliated funds, including funds of PIMCO ETF Trust, and unaffiliated funds (collectively, "Acquired Funds").

The Fund seeks to achieve its investment objective by investing under normal circumstances in a combination of affiliated and unaffiliated funds, which may or may not be registered under the Investment Company Act of 1940, as amended (the "1940 Act"), Fixed Income Instruments, equity securities, forwards and derivatives. "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. The Fund may invest, without limitation, in any of the Underlying PIMCO Funds (except the PIMCO CommoditiesPLUS® Strategy Fund and PIMCO CommodityRealReturn Strategy Fund®). 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 will invest either directly or indirectly (through a fund) in instruments that are economically tied to at least three countries (one of which may be the United States).

***Asset Allocations.*** The Fund seeks concurrent exposure to a broad spectrum of asset classes and other investments. The Fund will typically invest 20% to 80% of its net assets in equity-related investments (including investment in common stock, preferred securities, equity securities of real estate investment trusts and/or investment in the Domestic Equity-Related Underlying PIMCO Funds, the International Equity-Related Underlying PIMCO Funds and the PIMCO RealEstateRealReturn Strategy Fund, an Underlying PIMCO Fund and in other equity-related Acquired Funds). For the purposes of the above limitation, equity positions will be calculated on a net basis, meaning if short equity-related positions are held, they will be netted against long positions. With respect to its direct or indirect (through a fund) investments in equity securities, there is no limitation on the market capitalization range of the issuers in which the Fund may invest. The Fund may invest up to 25% of its total assets in commodity-related

investments (including exposure to commodity-related investments obtained through investment in the PIMCO Cayman Commodity Fund II Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the "Subsidiary"), and investment in the PIMCO CommoditiesPLUS® Strategy Fund and PIMCO CommodityRealReturn Strategy Fund®, Underlying PIMCO Funds). The Subsidiary is advised by PIMCO and primarily invests in commodity-linked derivative instruments backed by a portfolio of Fixed Income Instruments. As discussed in greater detail elsewhere in this prospectus, the Subsidiary (unlike the Fund) may invest without limitation in commodity-linked swap agreements and other commodity-linked derivative instruments. In order to comply with certain issuer diversification limits imposed by the Internal Revenue Code, the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund may invest, without limitation, in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest, without limitation, in high yield securities ("junk bonds"). The Fund may invest, without limitation, in securities and instruments that are economically tied to emerging market countries. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

***Asset Allocation Investment Process.*** The Fund's assets are not allocated according to a predetermined blend of shares of the Acquired Funds and/or direct investments in securities, instruments and other investments. Instead, when making allocation decisions among the Acquired Funds, securities, instruments and other investments, PIMCO considers various qualitative and quantitative factors relating to the U.S. and non-U.S. economies, and securities and commodities markets. These factors include projected growth trends in the U.S. and non-U.S. economies, forecasts for interest rates and the relationship between short- and long-term interest rates (yield curve), current and projected trends in inflation, relative valuation levels in the equity, fixed income, commodity and real estate markets and various segments within those markets, the outlook and projected growth of various industrial sectors, information relating to business cycles, borrowing needs and the cost of capital, political trends, data relating to trade balances, and labor information. PIMCO uses these factors to help determine the Fund's target asset allocation and to identify potentially attractive relative value and risk hedging strategies. 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.

The first step of the investment process is to determine the target asset allocation. PIMCO then considers incorporating relative value and risk hedging strategies. Relative value strategies may seek to improve the portfolio's risk-adjusted return potential. Risk hedging strategies may seek to reduce the Fund's exposure to certain severe, unanticipated market events that could significantly detract from returns.

Summary Prospectus

Once the target asset allocation, relative value strategies and risk hedging strategies have been determined, PIMCO then evaluates various combinations of affiliated or unaffiliated funds, securities, instruments and other investments to obtain the desired exposures and invests accordingly. Additional information for these 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 a Fund could lose money 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 a 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 a Fund to achieve its investment objective will depend upon the ability of the Acquired Funds to achieve their investment objectives

**Market Trading Risk:** the risk that an active secondary trading market for shares of a Fund that is an exchange-traded fund does not continue once developed, that such Fund may not continue to meet a listing exchange's trading or listing requirements, or that such Fund's shares trade at prices other than the Fund's net asset value

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.

**New Fund Risk:** the risk that a new fund's performance may not represent how the fund is expected to or may perform in the long term. In addition, new funds have limited operating histories for investors to evaluate and new funds may not attract sufficient assets to achieve investment and trading efficiencies

**Small Fund Risk:** the risk that a smaller fund may not achieve investment or trading efficiencies. Additionally, a smaller fund may be more adversely affected by large purchases or redemptions of fund shares

**Interest Rate Risk:** the risk that fixed income securities will decline in value because of an increase 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 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, 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

**Distressed Company Risk:** the risk that securities of distressed companies may be subject to greater levels of credit, issuer and liquidity risk than a portfolio that does not invest in such securities. Securities of distressed companies include both debt and equity securities. Debt securities of distressed companies are considered predominantly speculative with respect to the issuers' continuing ability to make principal and interest payments

**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, financial leverage and 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 futures, swaps and structured securities), including leverage, liquidity, interest rate, market, credit and management risks, and valuation complexity. Changes in the value of a derivative 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. The Fund's use of derivatives may result in

------

PIMCO Global Core Asset Allocation Fund

------

losses to the Fund, a reduction in the Fund's returns and/or increased volatility. Over-the-counter ("OTC") derivatives 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 OTC derivatives. The primary credit risk on derivatives 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 mutual 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 and/or adversely affect the value of derivatives and the Fund's performance

**Model Risk:** the risk that the Fund's investment models used in making investment allocation decisions may not adequately take into account certain factors or may rely on inaccurate data inputs, may contain design flaws or faulty assumptions, and may rely on incomplete or inaccurate data, any of which may result in a decline in the value of an investment in the Fund

**Commodity Risk:** the risk that investing in commodity-linked derivative instruments may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, public health emergencies, embargoes, tariffs and international economic, political and regulatory developments

**Equity Risk:** the risk that the value of equity 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 securities generally have greater price volatility than fixed income securities

**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

**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 reporting, accounting and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, or political changes, diplomatic developments 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 losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses. A Fund's investments in REITs or real estate-linked derivative instruments subject it to management and tax risks. In addition, privately traded REITs subject a 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. A Fund's investments in smaller companies subject it 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

**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 the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary's investments. The Subsidiary is 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 the Subsidiary will be achieved

4 **Summary Prospectus** \| PIMCO Funds

------

Summary Prospectus

------

**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, 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 will not fulfill its contractual obligations, causing a loss to the Fund

**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

**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 track the performance of the index it is designed to track, among other reasons, because of 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

**Tracking Error Risk:** the risk that the portfolio of a Fund that seeks to track the investment results of an underlying index may not closely track the underlying index for a number of reasons. The Fund incurs operating expenses, which are not applicable to the underlying index, and the costs of buying and selling securities, especially when rebalancing the Fund's portfolio to reflect changes in the composition of the underlying index. Performance of the Fund and the underlying index may vary due to asset valuation differences and differences between the Fund's portfolio and the underlying index due to legal restrictions, cost or liquidity restraints. The risk that performance of the Fund and the underlying index may vary may be heightened during periods of increased market volatility or other unusual market conditions. In addition, a Fund's use of a representative sampling approach may cause the Fund to be less correlated to the return of the underlying index than if the Fund held all of the securities in the underlying index

**Indexing Risk:** the risk that an Underlying PIMCO Fund that seeks to track the investment results of an underlying index is negatively affected by general declines in the asset classes represented by the underlying index

**LIBOR Transition Risk:** the risk related to the anticipated discontinuation of the London Interbank Offered Rate ("LIBOR"). Certain instruments held by the Fund rely in some fashion upon LIBOR. Although the transition process away from LIBOR has become increasingly well-defined in advance of the anticipated discontinuation date, there remains uncertainty regarding the nature of any replacement rate, and any potential effects of the transition away from LIBOR on the Fund or on certain instruments in which the Fund invests can be difficult to ascertain. The transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR and may result in a reduction in the value of certain instruments held by 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 a primary and a secondary broad-based securities market index and an index of similar funds. 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. Performance 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.*

The Fund's primary broad-based securities market index is the 60% MSCI All Country World Index (ACWI) and 40% Bloomberg Global Aggregate USD Hedged Index. The 60% MSCI All Country World Index (ACWI) and 40% Bloomberg Global Aggregate USD Hedged Index is a blended index. The MSCI All Country World Index is a free-float adjusted market capitalization weighted index that is designed to measure the equity market performance of developed and emerging markets. The MSCI All Country World Index consists of a group of country indexes comprising developed and emerging market indexes. The Bloomberg Global Aggregate Index (USD Hedged) provides a broad-based measure of the global investment-grade fixed income markets.

Lipper Alternative Global Macro Funds Average is a total return performance average of Funds tracked by Lipper, Inc. that, by prospectus language, invest around the world using economic theory to justify the decision-making process. The strategy is typically based on forecasts and analysis about interest rate trends, the general flow of funds, political

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.

**Tax Information**

The Fund's distributions are generally taxable to you as ordinary income, capital gains, or a combination of the two, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account, in which case distributions may be taxable upon withdrawal. Distributions paid by the Fund that are properly designated as "exempt interest dividends" normally will be exempt from federal income taxes, but may not be exempt from the federal alternative minimum tax.

**Payments to Broker-Dealers and Other Financial Firms**

If you purchase shares of the Fund through a broker-dealer or other financial firm (such as a bank), the Fund and/or its related companies (including PIMCO) may pay the financial firm for the sale of those shares of the Fund and/or related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial firm and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial firm's website for more information.
