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.

Fees and Expenses of the Fund

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then sell all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s fees and 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. Because the fund commenced operations on or following the date of this prospectus, there is no portfolio turnover information provided for the fund.

Investments, Risks, and Performance 

Principal Investment Strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of mid-cap companies. The fund defines a mid-cap company as a company whose (i) securities are represented in the Russell Midcap^® Index; or (ii) represented in an appropriate third party index and the company’s market capitalization falls within the market capitalization range of companies in the Russell Midcap^® Index, MSCI USA Mid Cap Index, or MSCI World Mid Cap Index (after systematically removing any companies that cannot reasonably be considered a mid-cap company from the high and low ends of the range of each index).

The market capitalizations of the companies in the indexes change over time and the indexes are periodically reconstituted to ensure that they continue to accurately reflect the mid-cap equity market. For example, as of December 31, 2025, the market capitalization range represented across these indexes (after removing any outlier companies) was $1.8 billion to $98 billion. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy.

The fund primarily invests in common stocks. The strategy attempts to create a portfolio with similar characteristics to the Russell Mid-Cap^® Index (“Index”) with the potential to provide excess returns relative to the Index. The fund uses a disciplined portfolio construction process whereby it weights each sector and industry similar to the Index. Within each sector and industry, the weighting of individual fund holdings can vary significantly from their weighting within the Index.

The fund attempts to outperform the Index by overweighting those stocks that are viewed favorably relative to their weighting in the Index, and underweighting or avoiding those stocks that are viewed negatively.

A portfolio oversight team, which includes the portfolio managers, is responsible for the overall structure of the fund and for developing rules for portfolio construction. The portfolio oversight team uses T. Rowe Price’s fundamental research by assigning equity analysts to select stocks for the fund within industries where they have focused expertise. The equity analysts are responsible for selecting stocks and determining the stocks’ weights within their industry-specific portfolios, subject to the oversight and discretion of the portfolio managers who work closely with the analysts.

At times, the fund may have a significant portion of its assets invested in the same economic sector.

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 unfavorable or uncertain market conditions, are summarized as follows:

Mid-cap stocks: Investments in securities issued by mid-cap companies are likely to be more volatile than investments in securities issued by large-cap companies. Mid-cap companies may have less seasoned management, narrower product lines, and less capital reserves and liquidity than large-cap companies, and are therefore more sensitive to economic, market, and industry changes.

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 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.

Stock investing: 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 stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry.

Sector exposure: Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

Index correlation: Because the fund weights each sector and industry similar to the Index, the fund’s ability to broadly reallocate its portfolio due to changes in outlook for a particular sector or industry is less than other actively managed funds with greater flexibility to overweight or underweight certain industries due to changes in market conditions. As a result, the fund’s performance may lag the performance of other actively managed funds with more flexible investment programs.

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.

Authorized Participant: Only Authorized Participants may engage in creation or redemption transactions directly with the fund. The fund has a limited number of institutions that may act as Authorized Participants. Authorized Participants have no obligation to submit creation or redemption orders, and there is no assurance that Authorized Participants will establish or maintain an active trading market for shares. To the extent an Authorized Participant cannot or will not engage in creation and redemption transactions, shares may be more likely to trade at a premium or discount to the fund’s NAV and to face trading halts and/or delisting. If the fund effects its creations or redemptions at least partially or fully for cash, rather than in-kind securities, the fund may incur certain costs, including brokerage costs in connection with investing cash received and may recognize capital gains in connection with cash redemptions.

ETF shares trading: Shares of the fund are listed for trading on a national securities exchange and are bought and sold in the secondary market at market prices. The market prices of shares are expected to fluctuate in response to changes in the fund’s NAV, the value of the fund’s holdings, and supply and demand for shares. Disruptions to creations and redemptions, significant market volatility, potential lack of an active trading market for the shares (including through a trading halt), or other factors may widen bid-ask spreads and result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the value of the fund’s holdings. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

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.

Because the fund commenced operations on or following the date of this prospectus, 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.

Purchase and Sale of Fund Shares

The fund issues and redeems shares at NAV only with Authorized Participants and only in large blocks of 50,000 shares (each, a “Creation Unit”). Individual fund shares may not be purchased or redeemed directly with the fund. An Authorized Participant may purchase or redeem a Creation Unit of the fund each business day that the fund is open in exchange for the delivery of a designated portfolio of in-kind securities and/or cash.

Individual fund shares may be purchased and sold only on a national securities exchange through brokers. Shares are listed for trading on the Nasdaq Stock Market LLC (“Nasdaq”) and because the shares will trade at market prices rather than at NAV, shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount). You may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the fund (bid) and the lowest price a seller is willing to accept for shares of the fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). All purchases and sales are made pursuant to this prospectus. Please refer to the fund’s website for additional information (troweprice.com).

Tax Information

The fund declares dividends, if any, and pays them annually. A distribution may consist of ordinary dividends, capital gains, and return of capital. Sales of fund shares and distributions by the fund 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), T. Rowe Price and its affiliates 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.
