**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 and then redeem all of your shares at the end of those periods, 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:

#### Investments, Risks, and Performance

#### Principal Investment Strategies
The fund is a retail money market fund managed in compliance with Rule 2a-7 under the Investment Company Act of 1940.

The securities purchased by the fund are subject to the maturity, quality, diversification, liquidity, and other requirements of Rule 2a-7. All securities purchased by the fund present minimal credit risk in the opinion of T. Rowe Price. The fund is managed to provide a stable share price of $1.00 by investing in high-quality, U.S dollar-denominated money market securities. Money market securities are generally high-quality, short-term obligations issued by companies or governmental entities. The fund's weighted average maturity will not exceed 60 calendar days, the fund's weighted average life will not exceed 120 calendar days, and the fund will not purchase any security with a remaining maturity longer than 397 calendar days

------

T. ROWE PRICE<sub>2</sub>

(unless otherwise permitted by Rule 2a-7, such as certain variable and floating rate instruments). When calculating its weighted average maturity, the fund may shorten its maturity by using the interest rate resets of certain adjustable rate securities. The fund may not take into account these resets when calculating its weighted average life.

In addition to investing in money market securities issued by corporations and financial institutions, the fund may also invest in U.S. Treasury securities and other U.S. government securities, and repurchase agreements thereon; municipal money market securities issued by state and local governments; and money market securities issued by foreign companies and financial institutions, which include U.S. dollar-denominated money market securities traded outside of the U.S. and U.S. dollar-denominated money market securities of foreign issuers traded in the U.S. There is no limit to the fund's investments in U.S. dollar-denominated money market securities of foreign issuers.

The fund may enter into repurchase agreements. A repurchase agreement is a contract under which the fund (buyer) purchases a security, usually a U.S. government or agency security, from a bank or well established securities dealer (seller) that requires the seller to repurchase the securities from the fund at a specific price on a designated date (which is often the next business day).

In accordance with the requirements for "retail money market funds" under Rule 2a-7, the fund has implemented policies and procedures designed to limit accounts to only those beneficially owned by natural persons. The fund has also obtained assurances from financial intermediaries that sell the fund that they have developed adequate procedures to limit accounts to only those beneficially owned by natural persons. Any new investors wishing to purchase shares will be required to demonstrate eligibility (for example, by providing their Social Security number). The fund will, upon advance written notification, involuntarily redeem investors that do not satisfy these eligibility requirements.

Pursuant to Rule 2a-7, if the fund's weekly liquid assets fall below 30% of its total assets, the fund's Board of Directors, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed or temporarily suspend redemptions from the fund for up to 10 business days during any 90–day period (i.e., a "redemption gate"). In addition, if the fund's weekly liquid assets fall below 10% of its total assets at the end of any business day, the fund must impose a 1% liquidity fee on shareholder redemptions unless the fund's Board of Directors determines that not doing so is in the best interests of the fund. Pursuant to Rule 2a-7, weekly liquid assets include cash, U.S. Treasuries, other government securities with remaining maturities of 60 days or less, or securities that mature or are subject to a demand feature within five business days.

#### Principal Risks
As with any fund, there is no guarantee that the fund will achieve its objective(s). 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. The fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the fund's liquidity falls below required minimums because of market conditions or other factors.

investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. T. Rowe Price Associates, Inc., has no legal obligation to provide financial support to the fund, and you should not expect that T. Rowe Price Associates, Inc., will provide financial support to the fund at any time.

Some money market funds have experienced significant pressures from shareholder redemptions, issuer credit downgrades, illiquid markets, and historically low yields on the securities they can hold. There have been a very small number of money market funds in other fund companies that have "broken the buck," which means that those funds' investors did not receive $1.00 per share for their investment in those funds. The SEC has proposed amendments to the rules applicable to money market funds, which, if adopted as proposed, could change the investment strategies, operations, and/or liquidity for certain money market funds. The potential for realizing a loss of principal in the fund could derive from:

**Market conditions** The value of the fund's investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund's holdings and markets generally, including political or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, or acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues such as the coronavirus pandemic and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

**Stable net asset value** The fund may not be able to maintain a stable $1.00 share price at all times. The fund's shareholders should not rely on or expect the fund's investment adviser or an affiliate to purchase distressed assets from the fund, enter into capital support agreements with the fund, make capital infusions into the fund, or take other actions to help the fund maintain a stable $1.00 share price.

**Interest rates** A decline in interest rates may lower the fund's yield, or a rise in the overall level of interest rates may cause a decline in the prices of fixed income securities held by the fund. The fund's yield will vary; it is not fixed for a specific period like the yield on a bank certificate of deposit. This is a disadvantage when interest rates are falling because the fund would have to reinvest proceeds of maturing securities at lower interest rates. During periods of extremely low short-term interest rates, the fund may not be able to maintain a positive yield. Given the current elevated inflation environment, risks associated with rising rates are currently heightened. In addition, the adoption of more stringent regulations governing the management of money market funds could have a negative effect on the fund's yield.

**Credit quality** An issuer of a debt instrument or a provider of credit support could suffer an adverse change in financial condition that results in a payment default (failure to make

------

scheduled interest or principal payments), a rating downgrade, or an inability to meet a financial obligation. Although the fund only purchases securities that present minimal credit risk in the opinion of T. Rowe Price, the credit quality of the fund's holdings could change rapidly during periods of market stress.

**Liquidity** The fund may not be able to sell a holding in a timely manner at its current carrying value. Periods of reduced liquidity in money markets could require the fund to liquidate its assets at inopportune times or at a depressed value, cause the fund to be unable to meet redemption requests without dilution of the remaining shareholders' interests in the fund, and potentially affect the fund's ability to maintain a $1.00 share price. In addition, the fund's Board of Directors has discretion to impose a liquidity fee, to temporarily suspend fund redemptions when permitted by applicable regulations, or to liquidate the fund if the fund's weekly liquid assets fall below 10%.

**Redemptions** The fund may be subject to periods of increased redemptions that could cause the fund to sell its assets at disadvantageous times or at a depressed value or loss, particularly during periods of declining or illiquid markets, and that could affect the fund's ability to maintain a stable $1.00 share price. Periods of heavy redemptions may result in the fund's level of weekly liquid assets falling below certain minimums required by Rule 2a-7, which may result in the fund's Board of Directors imposing a liquidity fee or redemption gate.

**Municipal securities** Investments in municipal securities may be adversely affected by changes in the financial condition of certain municipal securities issuers and the economy, as well as by events such as unfavorable legislative or political developments that impact the overall municipal securities market or certain sectors of the municipal securities market. Tax reform, including a lowering of individual or corporate tax rates, could reduce the attractiveness and overall demand for municipal bonds. The secondary market for certain municipal securities tends to be less developed and less liquid than many other securities markets.

**Repurchase agreements** A counterparty to a repurchase agreement may become insolvent or fail to repurchase securities from the fund as required, which could increase the fund's costs or prevent the fund from immediately accessing its collateral.

**Foreign investing** The fund's investments in foreign holdings may be adversely affected by local, political, social, and economic conditions overseas; greater volatility; reduced liquidity; or differences in settlement and regulatory standards.

**Cybersecurity breaches** The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund's assets, customer data and confidential shareholder information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund's service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality.

#### Purchase and Sale of Fund Shares
The fund generally requires a $2,500 minimum initial investment ($1,000 minimum initial investment if opening an IRA, a custodial account for a minor, or a small business retirement plan account). Additional purchases generally require a $100 minimum. These investment minimums generally are waived for financial intermediaries and certain employer-sponsored retirement plans submitting orders on behalf of their customers.

For investors holding shares of the fund directly with T. Rowe Price, you may purchase, redeem, or exchange fund shares by mail; by telephone (1-800-225-5132 for IRAs and nonretirement accounts; 1-800-492-7670 for small business retirement plans; and 1-800-638-8790 for institutional investors and financial intermediaries); or, for certain accounts, by accessing your account online through troweprice.com.

If you hold shares through a financial intermediary or retirement plan, you must purchase, redeem, and exchange shares of the fund through your intermediary or retirement plan. You should check with your intermediary or retirement plan to determine the investment minimums that apply to your account.

#### Tax Information
The fund declares dividends, if any, daily and pays them on the first business day of each month. Any capital gains are declared and paid annually, usually in December. Redemptions or exchanges of fund shares and distributions by the fund, whether or not you reinvest these amounts in additional fund shares, generally may be taxed as ordinary income or capital gains unless you invest through a tax-deferred account (in which case you will be taxed upon withdrawal from such account).

#### Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
