Investors should consider the investment objectives, risks, charges and expenses of the funds carefully before investing. This and other information are contained in the fund's prospectus and summary prospectus, if available, which may be obtained by contacting your investment professional or PIMCO representative or by visiting www.pimco.com. Please read them carefully before you invest or send money.

Performance quoted represents past performance. Past performance is not a guarantee or a reliable indicator of future results. Current performance may be lower or higher than performance shown. Investment return and principal value will fluctuate, so that Fund shares may be worth more or less than their original cost when redeemed. For ETFs, performance data current to the most recent month-end is available at www.pimco.com or call 888-400-4ETF. For mutual funds, performance data current to the most recent month-end is available at www.pimco.com or by calling (888) 87-PIMCO. For mutual fund Class A shares the maximum offering price (MOP) returns take into account the maximum initial sales charge.  For mutual Fund Class C shares the maximum offering price (MOP) returns take into the account the contingent deferred sales charge (CDSC). This charge may apply to shares redeemed during the first year of ownership.

The performance figures presented reflect the total return performance, unless otherwise noted, and reflect changes in share price, reinvestment of dividends, and capital gain distributions. NAV returns reflect the deduction of management fees and expenses. NAV and Market Price returns do not reflect broker sales charges or commissions and would be lower if they were deducted. All periods longer than one year are annualized. Periods less than one year are cumulative.

Investments made by a Fund and the results achieved by a Fund are not expected to be the same as those made by any other PIMCO-advised Fund, including those with a similar name, investment objective or policies. A new or smaller Fund’s performance may not represent how the Fund is expected to or may perform in the long-term. New Funds have limited operating histories for investors to evaluate and new and smaller Funds may not attract sufficient assets to achieve investment and trading efficiencies. A Fund may be forced to sell a comparatively large portion of its portfolio to meet significant shareholder redemptions for cash, or hold a comparatively large portion of its portfolio in cash due to significant share purchases for cash, in each case when the Fund otherwise would not seek to do so, which may adversely affect performance.

Differences in the Fund’s performance versus the index and related attribution information with respect to particular categories of securities or individual positions may be attributable, in part, to differences in the pricing methodologies used by the Fund and the index.

It is important to note that differences exist between the fund’s daily internal accounting records, the fund’s financial statements prepared in accordance with U.S. GAAP, and recordkeeping practices under income tax regulations. It is possible that the fund may not issue a Section 19 Notice in situations where the fund’s financial statements prepared later and in accordance with U.S. GAAP and/or the final tax character of those distributions might later report that the sources of those distributions included capital gains and/or a return of capital. Please see the fund’s most recent shareholder report for more details.

Although select Funds may seek to maintain stable distributions, the Funds’ distribution rates may be affected by numerous factors, including but not limited to changes in realized and projected market returns, fluctuations in market interest rates, Fund performance, and other factors. There can be no assurance that a change in market conditions or other factors will not result in a change in a Fund’s distribution rate or that the rate will be sustainable in the future.

For instance, during periods of low or declining interest rates, the Fund’s distributable income and dividend levels may decline for many reasons. For example, the Fund may have to deploy uninvested assets (whether from purchases of Fund shares, proceeds from matured, traded or called debt obligations or other sources) in new, lower yielding instruments. Additionally, payments from certain instruments that may be held by the Fund (such as variable and floating rate securities) may be negatively impacted by declining interest rates, which may also lead to a decline in the Fund’s distributable income and dividend levels.

PIMCO California Municipal Intermediate Value Fund and PIMCO National Municipal Intermediate Value Fund were funds registered under the Investment Company Act of 1940 and managed by Gurtin (the “Predecessor Funds”) that was reorganized into the Funds effective March 15, 2019. The Predecessor Funds had investment objectives and strategies that were, in all materials respects, the same as those of the Funds. The Funds’ performance for periods prior to the commencement of operations on March 18, 2019 is that of the Predecessor Funds. The performance of the Predecessor Funds has not been restated to reflect the fees, estimated expenses and fee waivers and/or expense limitations applicable to the Funds. If restated, the performance may have been higher or lower than the performance shown. The performance of each class of shares of the Funds will differ as a result of the different levels of fees and expenses applicable to each class of shares.

PIMCO California Municipal Opportunistic Value Fund and PIMCO National Municipal Opportunistic Value Fund were privately offered funds managed by Gurtin (the “Private Predecessor Funds”) that was reorganized into funds registered under the Investment Company Act of 1940 (the “1940 Act”) that were also managed by Gurtin (the “Registered Predecessor Funds,” together with the Private Predecessor Funds, the “Predecessor Funds”) on or about November 3, 2014. The Private Predecessor Funds were organized on November 16, 2009 and commenced operations on May 3, 2010 and had investment objectives and strategies that were, in all material respects, identical to those of the Registered Predecessor Funds, and were managed by Gurtin in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Registered Predecessor Funds. However, the Private Predecessor Funds were not registered as an investment company under the 1940 Act, and the Private Predecessor Funds were not subject to certain investment limitations, diversification requirements, liquidity requirements, and other restrictions imposed by the 1940 Act and the Internal Revenue Code of 1986 which, if applicable, may have adversely affected their performance. The Registered Predecessor Funds commenced operations on or about November 3, 2014 and had investment objectives and strategies that were, in all material respects, identical to those of the Funds, and were managed by Gurtin in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Funds. The Funds’ performance for periods prior to the commencement of operations on March 18, 2019 is that of the Predecessor Funds. The Funds’ performance for the period from May 3, 2010 to November 2, 2014 is that of the Private Predecessor Funds. The Fund’s performance for the period from November 3, 2014 to March 15, 2019 is that of the Registered Predecessor Funds. The performance of the Private Predecessor Funds were calculated net of the Private Predecessor Funds’ fees and expenses. The performance of the Predecessor Funds has not been restated to reflect the fees, estimated expenses and fee waivers and/or expense limitations of the Funds. If restated, the performance may have been higher or lower than the performance shown. The performance of each class of shares of the Funds will differ as a result of the different levels of fees and expenses applicable to each class of shares.

PIMCO RAE Emerging Markets Fund, PIMCO RAE US Fund and PIMCO RAE US Small Fund were privately offered funds managed by the Fund’s Sub-Adviser and were reorganized into the Funds as of 5 June 2015. For periods prior to the commencement of Funds’ operations, the Funds’ performance is that of the privately offered funds. The performance of the privately offered funds has not been restated to reflect the fees, estimated expenses and fee waivers and/or expense limitations applicable to each class of shares of the Funds. If the performance of the privately offered funds had been restated to reflect the applicable fees and expenses of each share class of the Funds, the performance may have been higher or lower. The privately offered fund began operations on 31 May 2006, 22 December 2004 and 29 September 2005, for the PIMCO RAE Emerging Markets Fund, PIMCO RAE US Fund and PIMCO RAE US Small Fund, respectively, and on 5 June 2015, were reorganized into the Funds. Prior to the reorganization, the privately offered funds had an investment objective and investment strategies that were, in all material respects, the same as those of the Funds, and were managed in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Funds. However, the privately offered funds were not registered as an investment company under the Investment Company Act of 1940 and were not subject to its requirements or requirements imposed by the Internal Revenue Code of 1986 which, if applicable, may have adversely affected their performance. The performance of each class of shares of the Funds will differ as a result of the different levels of fees and expenses applicable to each class of shares.

There is no assurance that any fund, including any fund that has experienced high or unusual performance for one or more periods, will experience similar levels of performance in the future. High performance is defined as a significant increase in either 1) a fund’s total return in excess of that of the fund’s benchmark between reporting periods or 2) a fund’s total return in excess of the fund’s historical returns between reporting periods. Unusual performance is defined as a significant change in a fund’s performance as compared to one or more previous reporting periods.

Funds typically offer different share classes, which are subject to different fees and expenses (which may affect performance), having different minimum investment requirements and are entitled to different services.

A Word About Risk: Investing in the bond market is subject to risks, including market, interest rate, issuer, credit, inflation risk, and liquidity risk. The value of most bonds and bond strategies are impacted by changes in interest rates. Bonds and bond strategies with longer durations tend to be more sensitive and volatile than those with shorter durations; bond prices generally fall as interest rates rise, and the current low interest rate environment increases this risk. Current reductions in bond counterparty capacity may contribute to decreased market liquidity and increased price volatility. Bond investments may be worth more or less than the original cost when redeemed. Investing in foreign denominated and/or domiciled securities may involve heightened risk due to currency fluctuations, and economic and political risks, which may be enhanced in emerging markets. Mortgage and asset-backed securities may be sensitive to changes in interest rates, subject to early repayment risk, and their value may fluctuate in response to the market's perception of issuer creditworthiness; while generally supported by some form of government or private guarantee there is no assurance that private guarantors will meet their obligations. Investing in securities of smaller companies tends to be more volatile and less liquid than securities of larger companies. Inflation-linked bonds (ILBs) issued by a government are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation; ILBs decline in value when real interest rates rise. Equities may decline in value due to both real and perceived general market, economic, and industry conditions. Commodities contain heightened risk including market, political, regulatory, and natural conditions, and may not be suitable for all investors. High-yield, lower-rated, securities involve greater risk than higher-rated securities; portfolios that invest in them may be subject to greater levels of credit and liquidity risk than portfolios that do not. Income from municipal bonds is exempt from federal income tax and may be subject to state and local taxes and at times the alternative minimum tax. Derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Investing in derivatives could lose more than the amount invested. Diversification does not ensure against loss.

Exchange Traded Funds ("ETF") are afforded certain exemptions from the Investment Company Act. The exemptions allow, among other things, for individual shares to trade on the secondary market. Individual shares cannot be directly purchased from or redeemed by the ETF. Purchases and redemptions directly with ETFs are only accomplished through creation unit aggregations or "baskets" of shares. Shares of an ETF are bought and sold at market price (not NAV). Brokerage commissions will reduce returns. Investment policies, management fees and other information can be found in the individual ETF's prospectus.

Buying or selling ETF shares on an exchange may require the payment of brokerage commissions. Due to the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment returns. Investment in Fund shares may not be advisable for investors who expect to engage in frequent trading.

The NAV of the Fund's shares is determined by dividing the total value of the Fund's portfolio investments and other assets, less any liabilities, by the total number of shares outstanding. Fund shares are valued as of the close of regular trading (normally 4:00 p.m., Eastern time) (the "NYSE Close") on each business day. The price used to calculate market returns ("Market Price") of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the national securities exchange on which shares of the Fund will be primarily listed for trading, as of the time that the Fund's NAV is calculated. The Fund's Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the market value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums (when market price is above NAV) or discounts (when market price is below NAV) reflect the differences (expressed as a percentage) between the NAV and the Market Price of the Fund on a given day, generally at the time the NAV is calculated. A discount or premium could be significant. ETF data in chart format displaying the frequency distribution of discounts and premiums of the Market Price against the NAV can be found for each Fund at www.pimcoetfs.com.

ETFs are subject to secondary market trading risks. Shares of an ETF will be listed for trading on an exchange, however, there can be no guarantee that an active trading market for such shares will develop or continue. There can be no guarantee that an ETF's exchange listing or ability to trade its shares will continue or remain unchanged. Shares of an ETF may trade on an exchange at prices at, above or below their most recent NAV. The per share NAV of an ETF is calculated at the end of each business day, and fluctuates with changes in the market value of the Fund's holdings. The trading prices of an ETF's shares fluctuate continuously throughout the trading day based on market supply and demand, which may not correlate to NAV. The trading prices of an ETF's shares may differ significantly from NAV during periods of market volatility, which may, among other factors, lead to the Fund's shares trading at a premium or discount to NAV.

Managed Accounts: The managed account strategies described in this material are offered by Pacific Investment Management Company LLC and are available exclusively through financial professionals. Managed accounts have a minimum asset level and may not be suitable for all investors. Financial professionals seeking more information should contact their managed accounts department or call their PIMCO representative

Target Date Funds: The Funds were designed to provide investors with a comprehensive retirement solution tailored to the time when they expect to retire and plan to start withdrawing money (the "target date"). Each Fund follows a target asset allocation schedule that changes over time to help reduce portfolio risk, increasing its exposure to conservative investments as the target date approaches. The principal value of the Fund is not guaranteed at any time, including the target date.
