c	T. Rowe Price Associates, Inc., has contractually agreed (through September 30, 2025) to waive its fees and/or bear any expenses (excluding interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses) that would cause the class' ratio of expenses to average daily net assets to exceed 0.59%. The agreement may only be terminated at any time after September 30, 2025, with approval by the fund's Board of Directors.

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. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. 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
Investor Class	$	60	$	211	$	377	$	858
I Class		42		142		252		573
Z Class		0		0		0		0

Portfolio Turnover The fund pays transaction costs, such as commissions, 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 the fund's shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 90.7% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in corporate debt securities. Holdings mainly consist of investment-grade bonds, although the fund has the flexibility to purchase some below investment-grade bonds (commonly referred to as "high-yield" or "junk" bonds). The fund may invest in other securities in an effort to enhance income and achieve capital growth. These include convertible securities and preferred stock; mortgage- and asset-backed securities, including mortgage-related derivatives; and U.S. Treasury and agency securities. In addition, up to 10% of the fund's total assets may be invested in non-U.S. dollar-denominated bonds and debt securities (including securities of issuers in emerging markets), and there is no limit on the fund's investments in U.S. dollar-denominated foreign securities. The fund may purchase securities of any maturity and its weighted average maturity will vary with market conditions.

At least 85% of the fund's net assets must have received an investment-grade rating (i.e., rated in one of the four highest rating categories) by at least one credit rating agency or, if not rated by any credit rating agency, deemed by the adviser to be of investment-grade quality. Such investment-grade investments could include "split-rated" securities, which are securities that are rated as investment grade by at least one credit rating agency but rated below investment grade by another agency. Up to 15% of the fund's net assets can be invested in below

SUMMARY	3

investment-grade securities including mortgage- and asset-backed securities. The fund will not purchase any individual bond that is rated below B (or equivalent) by any credit rating agency, and the fund's investments in bonds that are rated B (or equivalent) at the time of purchase will not exceed 5% of its net assets.

The fund may use a variety of derivatives, such as futures, forwards, and swaps for a number of purposes, such as for exposure or hedging. Specifically, the fund uses credit default swaps, credit default swap indexes (CDX), equity options, interest rate futures, interest rate future options, and interest rate swaptions. Credit default swaps are typically used to protect the value of certain portfolio holdings, as an alternative to cash bonds, and to manage the fund's overall credit risk exposure. A CDX is a swap on an index of credit default swaps. CDXs allow an investor to manage credit risk or take a position on a basket of credit entities (such as credit default swaps or a reference index) rather than transacting in a single-name credit default swap. Equity options are primarily used to create or hedge equity exposure. Interest rate futures, interest rate future options, and interest rate swaptions are typically used as an efficient means of managing the fund's exposure to interest rate changes and to adjust the portfolio's duration.

The fund's investment program provides some flexibility in seeking high income. Within the limits described, the fund can seek the most advantageous combination of securities. For example, when the difference is small between the yields of higher- and lower-rated securities, the fund may focus its investments in higher-quality issues. When the yield differential is large, the fund may move down the credit scale in search of higher yields. Likewise, if our outlook for foreign securities is favorable, the fund may purchase bonds issued by foreign companies at times when they offer higher yields than U.S. bonds of comparable quality and maturity.

Principal Risks

As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund's share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater in bad or uncertain market conditions, are summarized as follows:

Fixed income markets:Economic and other market developments can adversely affect the fixed income securities markets. At times, participants in these markets may develop concerns about the ability of certain issuers of debt instruments to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt instruments to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund's ability to sell the debt instruments in which it invests or to find and purchase suitable debt instruments.

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 economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and

T. ROWE PRICE	4

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.

Interest rates:A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests.

Prepayments and extensions: The fund is subject to prepayment risks because the principal on mortgage-backed securities, asset-backed securities, or any debt instrument with an embedded call option may be prepaid at any time, which could reduce the security's yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Extension risk may result from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities, and other callable debt instruments more volatile.

Foreign investing: Investments in the securities of non-U.S. issuers may be adversely affected by local, political, social, and economic conditions overseas; greater volatility; reduced liquidity; or decreases in foreign currency values relative to the U.S. dollar. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets.

Credit quality: An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative.

Junk investing: Investments in bonds that are rated below investment grade, commonly referred to as junk bonds, expose the fund to greater volatility and credit risk than investments in bonds that are rated investment grade. As a result, bonds rated below investment grade carry a higher risk of default and should be considered speculative.

Derivatives: The use of derivatives exposes the fund to additional volatility and potential losses. A derivative involves risks different from, and possibly greater than, the risks associated with investing directly in the assets on which the derivative is based, including liquidity risk, valuation risk, correlation risk, market risk, interest rate risk, leverage risk, counterparty and credit risk, operational risk, management risk, legal risk, and regulatory risk. Derivatives can be highly volatile, illiquid, and difficult to value, and changes in the value of a derivative may not properly

SUMMARY	5

correlate with changes in the value of the underlying asset, reference rate, or index. The fund could be exposed to significant losses if it is unable to close a derivatives position due to the lack of a liquid secondary trading market. The prices of derivatives may move in unexpected ways, especially in abnormal market conditions. Certain derivatives are also subject to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations. The use of derivatives includes the risk of potential operational issues, such as settlement issues. Derivatives are exposed to legal risks, such as the legality or enforceability of a contract. The adviser may not be able to accurately predict the direction of prices, economic factors, or other associated risks which could cause loss in value or impair the fund's efforts to reduce overall volatility. New regulations may make derivatives more costly, limit availability, or otherwise affect their value or performance.

Liquidity: The fund may not be able to meet requests to redeem shares issued by the fund without significant dilution of the remaining shareholders' interests in the fund. In addition, the fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Markets with lower overall liquidity could lead to greater price volatility and limit the fund's ability to sell a holding at a suitable price.

Convertible securities and preferred stocks: Convertible securities and preferred stocks carry credit and interest rate risk, along with other risks associated with both equity and fixed income securities, and convertible securities may be called back by the issuer prior to maturity at a price that is disadvantageous to the fund.

Active management: The fund's overall investment program and holdings selected by the fund's investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund's assets, confidential 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.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund's performance information represents only past performance (before and after taxes) and is not necessarily an indication of future results.

The following bar chart illustrates how much returns can differ from year to year by showing calendar year returns and the best and worst calendar quarter returns during those years for the fund's Investor Class. Returns for other share classes vary since they have different expenses.

The following table shows the average annual total returns for each class of the fund that has been in operation for at least one full calendar year. The fund's performance information included in the table is compared with a regulatory required index that represents an overall securities market (Regulatory Benchmark). In addition, the table may also include one or more indexes that more closely aligns to the fund's investment strategy (Strategy Benchmark(s)).

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. After-tax returns are calculated using the historical highest 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. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA. After-tax returns are shown only for the Investor Class and will differ for other share classes.

Purchase and Sale of Fund Shares

The Investor Class 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.

The I Class requires a $500,000 minimum initial investment per fund per account registration, although the initial investment minimum generally is waived or reduced for financial intermediaries, eligible retirement plans, certain client accounts for which T. Rowe Price or its affiliates have discretionary investment authority, qualifying directly held accounts, and certain other types of accounts.

The Z Class is only available to funds managed by T. Rowe Price and other advisory clients of T. Rowe Price or its affiliates that are subject to a contractual fee for investment management services. There is no minimum initial investment and no minimum for additional purchases.

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 other 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.
