dT. Rowe Price Associates, Inc., has contractually agreed (through September 30, 2022) to pay the operating expenses of the fund’s I Class excluding management fees; interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses (“I Class Operating Expenses”), to the extent the I Class Operating Expenses exceed 0.05% of the class’ average daily net assets. The agreement may only be terminated at any time after September 30, 2022, with approval by the fund’s Board of Directors. Any expenses paid under this agreement are subject to reimbursement to T. Rowe Price Associates, Inc., by the fund whenever the fund’s I Class Operating Expenses are below 0.05%. However, no reimbursement will be made more than three years from the date such amounts were initially waived or reimbursed. The fund may only make repayments to T. Rowe Price Associates, Inc., if such repayment does not cause the I Class Operating Expenses (after the repayment is taken into account) to exceed the lesser of: (1) the limitation on I Class Operating Expenses in place at the time such amounts were waived; or (2) the current expense limitation on I Class Operating Expenses.

eT. Rowe Price Associates, Inc., has contractually agreed to waive and/or bear all the Z Class’ expenses (excluding interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses) in their entirety. T. Rowe Price Associates, Inc. expects this fee waiver and/or expense reimbursement arrangement to remain in place indefinitely, and the agreement may only be amended or terminated 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 table above; 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
Investor Class	$22	$132
I Class	11	112
Z Class	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. A portfolio turnover rate is not shown since the fund had not commenced operations during its most recent fiscal year.

Investments, Risks, and Performance

Principal Investment Strategies

The fund seeks to track the investment returns of its benchmark index, the Bloomberg Barclays U.S. 1-5 Year Treasury TIPS Index. Under normal conditions, the fund invests at least 80% of its net assets (including any borrowings for investment purposes) in Treasury Inflation Protected Securities and in securities that are held in its benchmark index. The fund normally maintains a duration between one and five years, and it will vary consistent with the duration of the Bloomberg Barclays U.S. 1-5 Year Treasury TIPS Index, which measures the performance of inflation protected securities issued by the U.S. Treasury with remaining maturities between one and five years. As of September 30, 2020, the duration of the

SUMMARY 3

Bloomberg Barclays U.S. 1-5 Year Treasury TIPS Index was 1.49 years. Duration, which is expressed in years, is a calculation that attempts to measure the price sensitivity of a bond or bond fund to changes in interest rates. The longer a bond fund’s duration, the more sensitive that fund should be to changes in interest rates. For example, if interest rates rise by 1% and a fixed-rate bond has a duration of 5 years, it is estimated that the principal value of the bond will decrease by approximately 5%.

To be eligible for inclusion in the Bloomberg Barclays U.S. 1-5 Year Treasury TIPS Index, a security must be rated investment-grade, its principal and interest must be inflation-linked and denominated in U.S. dollars, have a fixed rate coupon with at least $250 million par amount outstanding (not adjusted for inflation indexation), and have greater than one year and less than five years remaining to maturity. The index is market value weighted and the securities represented in the index are updated on the last business day of each month. The composition of the index is rebalanced at each month-end and represents the fixed set of securities on which index returns are calculated for the next month. As of September 30, 2020, there were 14 securities in the index.

The adviser does not attempt to fully replicate the fund’s index by holding each of the bonds represented in the index. The portfolio will be structured to maintain an investment and risk profile, and overall characteristics, similar to the index. Using a sampling of securities, the adviser seeks to closely to track the returns of the fund’s index and more efficiently replicate the key risk factors of the index (such as maturity, duration, and credit quality) by attempting to capitalize on market inefficiencies through structural portfolio positioning and making small tactical bets on inflation, duration, and yield curve positioning.

Treasury Inflation Protected Securities, commonly known as “TIPS,” are income-generating instruments whose interest and principal payments are adjusted for inflation—a sustained increase in prices of goods and services that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the bond’s principal, follows a designated inflation index, such as the Consumer Price Index (CPI).

The fund will only purchase securities that are rated within the four highest credit rating categories (AAA, AA, A, BBB, or equivalent) at the time of purchase by at least one major credit rating agency or, if unrated, deemed to be of comparable quality by T. Rowe Price.

While most assets will typically be invested directly in TIPS and inflation-linked securities, the fund also uses interest rate futures and CPI swaps in keeping with its objective(s). Interest rate futures would typically be used to manage the fund’s exposure to interest rate changes or to adjust portfolio duration. CPI swaps would typically be used to manage the fund’s inflation risk, maintain efficient exposure to inflation-linked securities, or help realign the portfolio with the characteristics of the index.

The fund may sell holdings for a variety of reasons, such as to adjust the portfolio’s duration, better align its portfolio with the characteristics of its benchmark index, or to satisfy redemption requests.

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 during periods of market disruption or volatility, 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.

Inflation-linked securities When inflation is negative or concerns over inflation are low, the value and income of the fund’s investments in inflation-linked securities could fall and result in losses for the fund. During some extreme environments, the yield on an inflation-linked security may be negative.

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 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. 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.

Index investing Because the fund is managed to track the performance of its benchmark index, holdings are generally not reallocated based on changes in market conditions or the outlook for inflation, interest rates, and inflation-linked securities.

Tracking error The returns of the fund may deviate from the returns of its benchmark index (referred to as “tracking error”) because the fund incurs fees and transaction expenses while the index has no fees or expenses. Increased tracking error could also result from changes in the composition of the index or the timing of purchases and redemptions of fund shares. The fund does not attempt to fully replicate its benchmark index, which increases the potential for the fund’s performance to deviate from that of its index.

SUMMARY 5

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. 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 level of interest rates.

Derivatives The use of interest rate futures and CPI swaps potentially exposes the fund to additional volatility in comparison to investing directly in bonds and other debt instruments. These instruments may lack liquidity and be difficult to value, and may involve leverage so that small changes produce disproportionate losses for the fund, and instruments not traded on an exchange are subject to the risk that a counterparty to the transaction will fail to meet its obligations under the derivatives contract. The fund’s use of interest rate futures and CPI swaps involves the risk that anticipated interest rate movements and the outlook for inflation will not be accurately predicted, which could harm the fund’s performance.

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’ interest 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.

Cybersecurity breaches The fund could be harmed by intentional cyber-attacks 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.

Performance

Because the fund commenced operations in 2020, there is no historical performance information shown here. Performance history will be presented after the fund has been in operation for one full calendar year.
