Summary<sub>1</sub>

**Investment Objective(s)**

The fund seeks long-term growth of capital through investments primarily in the common stocks of established, non-U.S. companies.

**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 pay other fees, such as brokerage commissions or insurance contract fees and expenses, which are not reflected in the table and example below. If these additional fees and expenses were reflected, expenses shown would be higher.**

**Fees and Expenses of the Fund**

---

| | |
|:---|:---|
| **Annual fund operating expenses<br> (expenses that you pay each year as a<br> percentage of the value of your investment)** | **Annual fund operating expenses<br> (expenses that you pay each year as a<br> percentage of the value of your investment)** |
| &nbsp;&nbsp;Management fees | 0.65% |
| &nbsp;&nbsp;Other expenses | 0.32 |
| &nbsp;&nbsp;Total annual fund operating expenses | 0.97 |
| &nbsp;&nbsp;Fee waiver/expense reimbursement | (0.02)<sup>a</sup> |
| &nbsp;&nbsp;**Total annual fund operating expenses after fee <br> waiver/expense reimbursement** | **0.95** <sup>a</sup> |

---

<sup>a</sup> T. Rowe Price Associates, Inc. has contractually agreed to indefinitely waive its fees and/or bear any expenses (excluding interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; acquired fund fees and expenses; and 12b-1 fees, if any) that would cause the fund's ratio of expenses to average daily net assets to exceed 0.95%. The agreement may only be terminated with approval by the fund's shareholders. Fees waived and expenses borne by T. Rowe Price Associates, Inc. are subject to reimbursement by the fund (or class'), provided no reimbursement will be made if it would result in the fund's (or class') expense ratio exceeding its applicable limitation at the time of the waiver/payment or reimbursement, whichever is lower. No reimbursement will be made more than three years after any waiver or payment.

**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** |
| $97 | $303 | $525 | $1166 |

---

**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 42.0% 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 (plus any borrowings for investment purposes) in stocks. 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 expects to primarily invest in stocks outside the U.S. and to diversify broadly across a variety of industries in developed and emerging market countries throughout the world. The fund normally invests in at least five countries and may purchase the stocks of companies of any size, but its focus is typically on large-cap companies. The fund relies on MSCI Inc., a third-party provider of benchmark indexes and data services, or another unaffiliated data provider to determine the country assigned to a security.

While the adviser invests with an awareness of the global economic backdrop and the adviser's outlook for certain industries, sectors, and individual countries, the adviser's decision-making process focuses on bottom-up stock selection. Country allocation is driven largely by stock selection, though the adviser may limit investments in markets or industries that appear to have poor overall prospects.

<u>T. Rowe Price</u> <u>2</u>

Security selection reflects a growth style. The adviser relies on a global team of investment analysts dedicated to in-depth fundamental research in an effort to identify high-quality companies capable of achieving and sustaining above-average, long-term earnings growth. The adviser seeks to purchase stocks of companies at reasonable prices in relation to present or anticipated earnings, cash flow, or book value.

In selecting investments the adviser generally favors companies with one or more of the following characteristics:

● leading or improving market position;

● attractive business niche;

● attractive or improving franchise or industry position;

● seasoned management;

● stable or improving revenues, earnings, and/or cash flow; and

● sound or improving balance sheet.

The fund typically has significant investments in Asian and developed European countries.

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:

**Foreign investing:** 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.

**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 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.

**Large-cap stocks:** Securities issued by large-cap companies tend to be less volatile than securities issued by small- and mid-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small- and mid-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

**Growth investing:** The fund's growth approach to investing could cause it to underperform other stock funds that employ a different investment style. Growth stocks tend to be more volatile than certain other types of stocks and their prices may fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market.

**Investing in Europe:** The European financial markets have experienced increased volatility due to concerns about economic downturns, political unrest, war, military conflict, economic sanctions, rising government debt levels, inflation, energy crises, and public health pandemics, and these events may continue to significantly affect all of Europe. The economies and markets of European countries are often connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. European economies could be significantly affected by, among other things, rising unemployment, the imposition or unexpected elimination of fiscal and monetary controls by member countries of the European Economic and Monetary Union, uncertainty surrounding the euro, the success of governmental actions to reduce budget deficits, and Russia's ongoing military conflict in Ukraine.

Summary<sub>3</sub>

**Investing in Asia:** Many Asian economies have at various times been negatively affected by inflation, currency devaluations, an over-reliance on international trade and exports, particularly for certain commodities, political and social instability, and less developed financial systems and securities trading markets. Trade restrictions, unexpected decreases in exports, changes in government policies, expropriation and/or nationalization of assets, confiscatory taxation, or natural disasters could have a significant impact on companies doing business in Asia. The Asian region may be significantly affected by political unrest, military conflict, economic sanctions, and less demand for Asian products and services.

**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.

**Emerging markets:** Investments in emerging market countries are subject to greater risk and overall volatility than investments 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 associated with investing outside the U.S., emerging markets are more susceptible to governmental interference, political and economic uncertainty, local taxes and restrictions on the fund's investments, less efficient trading markets with lower overall liquidity, and more volatile currency exchange rates.

**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.

**Currency exposure:** Because the fund invests in holdings denominated in foreign currencies, the fund is subject to the significant risk that it could experience losses based solely on the weakness of foreign currencies versus the U.S. dollar and changes in the exchange rates between such currencies and the U.S. dollar.

**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 and is not necessarily an indication of future results. Figures shown reflect fees and expenses associated with an investment in the fund, but do not reflect insurance contract fees and expenses. If insurance contract fees and expenses were included, results would have been lower.

**Purchase and Sale of Fund Shares**

The fund is not sold directly to the general public but is instead offered as an underlying investment option for variable annuity or variable life insurance contracts. Although the fund does not require a minimum amount for initial or subsequent purchases from insurance companies, your insurance company may impose investment minimums for your purchases of the fund.

You may purchase, redeem, or exchange shares of the fund on any day the New York Stock Exchange is open for business. You must purchase, redeem, and exchange shares through your insurance company.

Summary<sub>5</sub>

**Tax Information**

The fund distributes any dividends and capital gains to its shareholders, which are the insurance company separate accounts that sponsor your variable annuity or variable life insurance contract. Variable product owners seeking to understand the tax consequences of their investment, including redemptions of fund shares and the impact of dividend and capital gains distributions by the fund, should consult with the insurance company that issued their variable product or refer to their variable annuity or variable life insurance contract prospectus.

**Payments to Insurance Companies, Broker-Dealers, and Other Financial Intermediaries**

The fund is generally available only through variable annuity or variable life insurance contracts. The fund and/or its related companies may make payments to a sponsoring insurance company or other financial intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the insurance company or other financial intermediary to recommend the fund over another investment option or by influencing an insurance company to include the fund as an underlying investment option in a variable contract. The prospectus (or other offering document) for your variable contract may contain additional information about these payments. Ask your insurance company or financial intermediary, or visit your insurance company's or financial intermediary's website, for more information.
