Investment Objective(s)

The fund seeks the highest total return over time consistent with an emphasis on both capital growth and income.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below.

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:

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 period June 18, 2025 through May 31, 2026, the fund’s portfolio turnover rate was 57.0% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund pursues its objective(s) by investing in a diversified portfolio of other T. Rowe Price equity and fixed income mutual funds that represent various asset classes and sectors. The fund’s allocations among underlying T. Rowe Price mutual funds will change over time in relation to the fund’s target retirement date.

The fund is managed based on the specific retirement year (target date 2070) included in its name and assumes a retirement age of 65. The target date refers to the approximate year an investor in the fund would plan to retire and likely stop making new investments in the fund. The fund is primarily designed for an investor who anticipates retiring at or about the target date and who plans to withdraw the value of the account in the fund gradually after retirement. However, if an investor retires earlier or later than age 65, the fund may not be an appropriate investment even if the investor retires on or near the fund’s target date.

Over time, the fund’s allocations to the broad asset classes (“Equity” and “Fixed Income”), and to the sectors and underlying funds used to represent those asset classes, will change according to a predetermined “glide path” shown in the following chart (the left axis indicates the overall neutral allocation to equity funds with the remainder of the allocation to fixed income funds). Equity allocations generally consist of investments in underlying funds that focus on stocks, and fixed income allocations generally consist of investments in underlying funds that focus on bonds and other debt instruments. The glide path represents the shifting of asset classes over time and shows how the fund’s asset mix becomes more conservative–both prior to and after retirement–as time elapses. This reflects the need for reduced market risks as retirement approaches and the need for lower portfolio volatility after retiring. Although the glide path is meant to dampen the fund’s potential volatility as retirement approaches, the fund is not designed for a lump sum redemption at the retirement date. The fund pursues an asset allocation strategy that promotes asset accumulation prior to retirement, but it is intended to also serve as a post-retirement investment vehicle with allocations designed to support an income stream made up of regular withdrawals throughout retirement along with some portfolio growth that exceeds inflation. After the target date, the fund is designed to balance longevity and inflation risks along with the need for some income, although it does not guarantee a particular level of income.

TARGET FUNDS

At the target date, the glide path provides for a neutral allocation to equity of 42.5%. The fund’s overall exposure to equity will continue to decline until approximately 30 years after its target date, when its neutral allocations to equity and fixed income will remain unchanged. There are no maturity restrictions within the fund’s overall allocation to fixed income, although the underlying fixed income funds in which the fund invests may impose specific limits on maturity or credit quality. The allocations are referred to as “neutral” allocations because they do not reflect any tactical decisions made by T. Rowe Price to overweight or underweight a particular asset class or sector based on its market outlook. The target allocations assigned to the broad asset classes (Equity and Fixed Income), which reflect any tactical decisions resulting from market outlook, are not expected to vary from the neutral allocations set forth in the glide path by more than plus or minus 5%. The target allocations and actual allocations may differ due to significant market movements or cash flows.

The following table illustrates how the portfolio is generally expected to be allocated between the broad asset classes and the underlying T. Rowe Price mutual funds that are used to represent those asset classes and specific sectors. The fund invests in underlying funds that do not charge a management fee or in Z Class shares of an underlying fund when it is available. T. Rowe Price is contractually obligated to waive and/or bear all of the Z Class’ expenses, with certain limited exceptions. The fund’s overall allocation to equity is represented by a diversified mix of U.S. and international equity funds that employ both growth and value investment approaches and consist of large-cap, mid-cap, and small-cap stocks. The fund’s overall allocation to fixed income is represented by a “core” fixed income component designed to have lower overall volatility and a “diversifying” fixed income component designed to respond to a variety of market conditions and improve risk adjusted returns. The information in the table represents the neutral allocations for the fund as of August 1, 2026. The numbers may not add to 100% due to rounding. Updated allocations between equity funds and fixed income funds, and actual allocations to each underlying T. Rowe Price mutual fund, are available through troweprice.com. T. Rowe Price may periodically rebalance or modify the asset mix of the underlying funds and change the underlying fund allocations.

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. You may experience losses, including losses near, at, or after the target retirement date. There is no guarantee that the fund will provide adequate income at and through your retirement. The principal risks of investing in this fund, which may be even greater in unfavorable or uncertain market conditions, are summarized as follows:

Active management/Asset allocation: The fund’s overall level of risk will directly correspond to the risks of the underlying funds in which it invests. By investing in many underlying funds, the fund has partial exposure to the risks of different areas of the market. However, the selection of the underlying funds and the allocation of the fund’s assets among the various asset classes, market sectors, and investment styles represented by those underlying funds could cause the fund to underperform other funds with a similar benchmark or investment objective(s). There can be no assurance that the assets of the fund will be allocated as intended. Any decision to adjust the composition of, or allocation to, an underlying fund will have an effect on the fund’s overall investment performance, including a potentially material, adverse effect.

Investments in other funds: The fund bears the risk that its underlying funds will fail to successfully employ their investment strategies. One or more underlying fund’s underperformance or failure to meet its investment objective(s) as intended could cause the fund to underperform similarly managed funds.

Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by an underlying fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of an underlying fund’s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), 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 pandemics) 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.

Equity exposure: An underlying equity fund’s share price can fall because of weakness in the overall stock markets, a particular industry, or specific holdings. Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of an underlying equity fund may decline due to general weakness or volatility in the stock markets, adverse conditions impacting a particular industry or market sector, or factors affecting an investment style or market capitalization targeted by the fund.

Foreign investing: Underlying funds with exposure to foreign investments carry greater risk because non-U.S. securities tend to be more volatile and have lower overall liquidity and trading volume than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. Further, securities of non-U.S. issuers are subject to trading markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. Investments in emerging market countries are subject to greater risk and overall volatility than investments in developed markets.

Emerging markets: Investing in underlying funds that hold securities of issuers in emerging market countries involves greater risk and overall volatility than investing in underlying funds that hold securities of issuers in the U.S. and other developed markets. Emerging market countries tend to have economic structures that are less diverse and mature, less developed legal and regulatory regimes, and political systems that are less stable, than those of developed countries. In addition to the risks normally associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on an underlying fund’s investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates.

Market capitalization: Because the fund invests in certain underlying funds that focus on a particular market capitalization, its share price may be negatively affected if investing in that market capitalization falls out of favor. Small- and mid-cap companies often have less experienced management, more limited financial resources, and less publicly available information than large-cap companies, and tend to be more sensitive to changes in overall economic conditions. As a result, investments in small-cap and mid-cap companies are likely to be more volatile than investments in large-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and they may be less capable of responding quickly to competitive challenges and industry changes.

Investment style: Because the fund invests in certain underlying funds that focus on growth stocks and certain underlying funds that focus on value stocks, its share price may be negatively affected if either investing approach falls out of favor. Growth stocks tend to be more volatile than the overall stock market and are more sensitive to changes in current or expected earnings. Value stocks carry the risk that investors will not recognize their intrinsic value for a long time (or at all) or that they are actually appropriately priced at a low level.

Inflation: To the extent the fund invests in underlying funds that are designed to provide protection against the impact of inflation, those investments could adversely affect the fund’s performance when inflation or expectations of inflation are low. During such periods, the values of an underlying fund’s investments in inflation-linked securities or stocks designed to outperform the overall stock market during periods of high or rising inflation could fall and result in losses for the fund, causing the fund to lag the performance of similarly managed funds.

Liquidity: A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit an underlying fund’s ability to purchase or sell holdings in a timely manner at a desired price. Reduced liquidity can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Large redemptions may also have a negative impact on an underlying fund’s overall liquidity.

New fund: Because the fund is new, it may have more limited operating history, fewer shareholders, and less assets than funds that have been in existence for longer periods. It may be more difficult to evaluate the investment program and portfolio manager of a fund with a limited performance track record. Due to the fund’s size, large shareholder purchases or redemptions could require the fund to buy or sell holdings at unfavorable times or maintain greater cash reserves than desired, create tax implications for the fund and its shareholders, and make it difficult to invest fully in accordance with the fund’s investment program.

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. A cybersecurity breach could result in a loss for the fund or affect its ability to operate as intended either temporarily or for an extended period, which may include limits on the ability to obtain pricing information for the fund’s investments, calculate its net asset value, and satisfy redemptions.
