The Fund’s Objective

The Fund seeks current income with liquidity and stability of principal.

Fees and Expenses of the Fund

The following 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 examples below.

ANNUAL FUND OPERATING EXPENSES (Expenses that you pay each year as a percentage of the value of your investment)
	Agency
Management Fees	0.08%
Distribution (Rule 12b-1) Fees	NONE
Other Expenses	0.19
Service Fees	0.15
Remainder of Other Expenses	0.04
Total Annual Fund Operating Expenses	0.27
Fee Waivers and/or Expense Reimbursements 1	-0.01
Total Annual Fund Operating Expenses after Fee Waivers and/or Expense Reimbursements 1	0.26

The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.26% of the average daily net assets of Agency Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 6/30/27, at which time it will be determined whether such waivers will be renewed or revised. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 6/30/27 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:
	1 Year	3 Years	5 Years	10 Years
AGENCY SHARES ($)	27	86	151	342

The Fund’s Main Investment Strategy

Under normal conditions, the Fund invests its assets exclusively in:

●

obligations of the U.S. Treasury, including Treasury bills, bonds and notes and other obligations issued or guaranteed by the U.S. Treasury, and

●

repurchase agreements fully collateralized by U.S. Treasury securities.

The debt securities described above carry different interest rates, maturities and issue dates.

The Fund is a money market fund managed in the following manner:

●

The Fund seeks to maintain a net asset value (“NAV”) of $1.00 per share.

●

The dollar-weighted average maturity of the Fund will be 60 days or less and the dollar-weighted average life to maturity will be 120 days or less.

●

The Fund will only buy securities that have remaining maturities of 397 days or less or securities otherwise permitted to be purchased because of maturity shortening provisions under applicable regulation.

●

The Fund invests only in U.S. dollar-denominated securities.

●

The Fund seeks to invest in securities that present minimal credit risk.

The Fund will generally hold a portion of its assets in cash, primarily to meet redemptions.

The Fund intends to continue to qualify as a “government money market fund,” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended (“Investment Company Act”).“Government money market funds” are required to invest at least 99.5% of their assets in (i) cash, (ii) securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities and/or (iii) repurchase agreements that are collateralized fully, and are exempt from requirements that permit money market funds to impose a liquidity fee. While the J.P. Morgan Funds’ Board of Trustees (the “Board”) may elect to subject the Fund to liquidity fee requirements in the future, the Board has not elected to do so at this time. A government money market fund may also include investments in other government money market funds as an eligible investment for purposes of the 99.5% requirement above.

The Fund’s adviser seeks to develop an appropriate portfolio by considering the differences in yields among securities of different maturities and issue dates.

The Fund’s Main Investment Risks

The Fund is subject to management risk and the Fund may not achieve its objective if the adviser’s expectations regarding particular instruments or interest rates are not met.

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk due to certain changes in monetary policy. It is difficult to predict the pace at which central banks or monetary authorities may change interest rates or the timing, frequency, or

magnitude of such changes. Any such changes could be sudden and could expose debt markets to significant volatility and reduced liquidity for Fund investments.

Credit Risk. The Fund’s investments are subject to the risk that issuers, guarantors and/or counterparties will fail to make payments when due or default completely. Prices of the Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.

Government Securities Risk. U.S. Government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. The income generated by investments may not keep pace with inflation. Actions by governments and central banking authorities could result in changes in interest rates. Periods of higher inflation could cause such authorities to raise interest rates, which may adversely affect the Fund and its investments. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal (e.g., Congressional debt ceiling impasses). This would result in losses to the Fund. U.S. Government securities include zero coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s

performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Net Asset Value Risk. There is no assurance that the Fund will meet its investment objective of maintaining a NAV of $1.00 per share on a continuous basis. Furthermore, there can be no assurance that the Fund’s affiliates will purchase distressed assets from the Fund, make capital infusions, enter into capital support agreements or take other actions to ensure that the Fund maintains a NAV of $1.00 per share. In the event any money market fund fails to maintain a stable NAV, other money market funds, including the Fund, could face a universal risk of increased redemption pressures, potentially jeopardizing the stability of their NAVs. In general, certain other money market funds have in the past failed to maintain stable NAVs and there can be no assurance that such failures and resulting redemption pressures will not occur in the future.

Repurchase Agreement Risk. There is a risk that the counterparty to a repurchase agreement will default or otherwise become unable to honor a financial obligation and the value of your investment could decline as a result.

Risk Associated with the Fund Holding Cash. The Fund will generally hold a portion of its assets in cash, primarily to meet redemptions. Cash positions may hurt performance and may subject the Fund to additional risks and costs, such as increased exposure to the custodian bank holding the assets and any fees imposed for large cash balances.

Prepayment Risk. The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments or redemptions occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.
