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	$	45	$	151	$	278	$	647
I Class		37		116		202		456
Advisor Class		83		259		450		1,002
R Class		110		352		622		1,394
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 171.6% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund will invest at least 80% of its net assets in income-producing securities, which may include, but are not limited to, U.S. government and agency obligations, mortgage- and asset-backed securities (including commercial mortgage-backed securities), corporate bonds, foreign bonds, and Treasury Inflation Protected Securities. For purposes of this 80% policy, the fund

SUMMARY 3

includes derivative instruments that are linked to, or provide investment exposure to, income-producing securities.

Over the long term, the fund seeks to achieve its objective by investing primarily in income-producing securities that possess what the fund believes are favorable total return (income plus increases in principal value) characteristics.

Eighty percent (80%) of the debt securities purchased by the fund will be rated investment grade (i.e., rated in one of the four highest rating categories) by each of the major credit rating agencies (S&P Global Ratings, Moody’s, and Fitch) that have assigned a rating to the security or, if unrated, deemed by the adviser to be of investment-grade quality. Up to 15% of the fund’s net assets may be invested in “split-rated securities,” which are securities that have been rated investment grade by at least one rating agency but below investment grade by another rating agency. The fund may maintain a net exposure of up to 5% of its net assets in instruments (through direct holdings and derivatives) that have received below investment-grade ratings from each of the rating agencies that have assigned ratings to the instruments or, if unrated, deemed by the adviser to be below investment-grade quality (including high yield or “junk” bonds). The fund may invest up to 20% of its net assets in non-U.S. dollar-denominated foreign debt securities (including securities of issuers in emerging markets) and take currency positions to hedge this exposure as well as to capture appreciation from favorable currency changes.

The fund has considerable flexibility in seeking high income. There are no maturity restrictions so the fund can purchase long-term bonds, which tend to have higher yields than shorter-term bonds. In addition, when there is a large yield difference between the various quality levels, the fund may move down the credit scale and purchase lower-rated bonds with higher yields. When the difference is small or the outlook warrants, the fund may concentrate investments in higher-rated issues.

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 interest rate futures, credit default swaps, forward currency exchange contracts, and options. Interest rate futures would typically be used to manage the fund’s exposure to interest rate changes or to adjust portfolio duration. Credit default swaps can be 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. Forward currency exchange contracts would be used to gain exposure to certain currencies expected to increase or decrease in value relative to other currencies or to protect the fund’s foreign bond holdings from adverse currency movements relative to the U.S. dollar.

The fund may also purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the “to-be-announced” (TBA) market. With TBA transactions, the particular securities to be delivered are not identified at the trade date, but the delivered securities must meet specified terms and standards. The fund will generally enter into TBA transactions with the intention of taking possession of the underlying mortgage-backed securities. However, in an effort to obtain underlying mortgage-backed securities on more preferable terms or to enhance returns, the fund may extend the settlement by entering into

T. ROWE PRICE 4

“dollar roll” transactions in which the fund sells mortgage-backed securities and simultaneously agrees to purchase substantially similar securities on a future date. The fund also expects to engage in short sales of TBA mortgages, including short sales on TBA mortgages the fund does not own, to potentially enhance returns or manage risk.

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 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:The prices of, and the income generated by, debt instruments held by the fund may be affected by changes in 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, such as the discontinuation and replacement of benchmark rates, are likely to affect the interest rates or yields of the securities in which the fund invests.

SUMMARY 5

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.

LIBOR transition: Many financial instruments use a floating rate based on the London Interbank Offered Rate, or “LIBOR,” which is the offered rate for short-term Eurodollar deposits between major international banks. As of June 2023, the publication of all settings of LIBOR has been phased out (although certain synthetic USD LIBOR rates will be published through September 2024). The elimination of LIBOR or changes to other reference rates or any other changes or reforms to the determination or supervision of reference rates could have an adverse impact on the market for, or value of, any securities or payments linked to those reference rates, which may adversely affect the fund’s performance and/or net asset value.

TBAs and dollar rolls: Although the securities that are delivered in TBA transactions must meet certain standards, there is a risk that the actual securities received by the fund may be less favorable than what was anticipated when entering into the transaction. TBA transactions are collateralized but they still involve the risk that a counterparty will fail to deliver the security, exposing the fund to potential losses. Whether or not the fund takes delivery of the securities at the termination date of a TBA transaction, it will nonetheless be exposed to changes in the value of the underlying investments during the term of the agreement. Forward settling securities, such as TBAs, involve leverage which may magnify investment risks and can cause losses to be realized more quickly. In addition, the fund’s portfolio turnover rate and transaction costs are increased when the fund enters into dollar roll transactions.

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 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.

T. ROWE PRICE 6

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.

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.

Portfolio turnover: High portfolio turnover may adversely affect the fund’s performance and increase transaction costs, which could increase the fund’s expenses. High portfolio turnover may also result in the distribution of higher capital gains when compared with a fund with less active trading policies, which could have an adverse tax impact if the fund’s shares are held in a taxable account.

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.

SUMMARY 9

Purchase and Sale of Fund Shares

The Investor Class, Advisor Class, and R Class generally require 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. Advisor Class and R Class shares may generally only be purchased through a financial intermediary or retirement plan.

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.
