Portfolio Turnover (% of average value of portfolio). 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. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example above, affect the Fund's performance.

Period
1/1/2025 - 12/31/2025 70 %

Principal Investment Strategies. Under normal circumstances, the Fund invests at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes) in equity securities of emerging market companies.

The equity securities in which the Fund invests are primarily publicly traded common stocks but may also include warrants and preferred stocks. For purposes of the Fund's 80% investment policy, equity securities also include depositary receipts (including unsponsored depositary receipts and American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary Receipts ("GDRs")), which are certificates typically issued by a bank or trust company that represent ownership interests in securities of non-U.S. companies, and participation notes ("P-Notes"), which are derivative instruments designed to replicate equity exposure in certain foreign markets where direct investment is either impossible or difficult due to local investment restrictions. The Fund may invest in initial public offerings ("IPOs") and securities of companies with any market capitalization. Certain instruments in which the Fund invests may be illiquid or thinly-traded securities. The Fund may invest in exchange traded funds ("ETFs"), including commodity ETFs that provide exposure to or invest in gold.

The Fund may also invest in A Shares of companies based in the People's Republic of China ("China") that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange through the Shanghai - Hong Kong and Shenzhen - Hong Kong Stock Connect programs ("Stock Connect"). Stock Connect is a mutual stock market access program designed to, among other things, enable foreign investments in China.

The Fund considers a company to be an emerging market company if: (i) at least 50% of the company's assets are located in emerging market countries; (ii) at least 50% of the company's revenue is generated in emerging market countries; (iii) the company is organized, conducts its principal operations, or maintains its principal place of business or principal manufacturing facilities in an emerging market country; (iv) the company's securities are traded principally in an emerging market country; or (v) GQG Partners LLC ("Sub-Adviser") otherwise believes that the company's assets are exposed to the economic fortunes and risks of emerging market countries (because, for example, the Sub-Adviser believes that the company's growth is dependent on emerging market countries). The Fund considers classifications by the World Bank, the International Finance Corporation, the International Monetary Fund and the Fund's benchmark index provider in determining whether a country is an emerging market country. Emerging market countries generally include every country in the world except the U.S., Canada, Japan, Australia, New Zealand, and most of the countries in Western Europe. From time to time, the Fund may focus its investments in a particular country or geographic region.

In managing the Fund's investments, the Sub-Adviser pursues a "growth style" of investing through which it seeks to capture market upside while limiting downside risk through full market cycles by combining a rigorous screening process with fundamental analyses to seek to identify and invest in companies that the Sub-Adviser believes have favorable long-term economic prospects. Specifically, the Sub-Adviser seeks to buy companies that it believes are reasonably priced, have strong fundamental business characteristics, sustainable relative earnings growth and the ability to outperform peers over a full market cycle, and can sustain the value of their securities in a market downturn. The Sub-Adviser may also purchase stocks that do not fall into the traditional "growth" style box. The Sub-Adviser may sell a company if it believes that the company's long-term competitive advantage or relative earnings growth prospects have deteriorated, or the Sub-Adviser has otherwise lost conviction in the company. The Sub-Adviser also may sell a company if the company has met its price target or is involved in a business combination, if the Sub-Adviser identifies a more attractive investment opportunity, or the Sub-Adviser wishes to reduce the Fund's exposure to the company or a particular country or geographic region.

The Fund is classified as a "non-diversified" fund, as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), which means that it may invest more of its assets in fewer issuers than "diversified" mutual funds.

Principal Risks of Investing in the Fund. An investment in the Fund is not guaranteed. As with any mutual fund, the value of the Fund's shares will change, and you could lose money by investing in the Fund. The principal risks associated with investing in the Fund include:

2
· Equity securities risk - Common and preferred stocks represent equity ownership in a company. Stock markets are volatile, and equity securities generally have greater price volatility than fixed-income securities. The price of equity or equity-related securities will fluctuate and can decline and reduce the value of a portfolio investing in equity or equity-related securities. The value of equity or equity-related securities purchased or held by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.
· Market risk - Portfolio securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic, political, or regulatory conditions, inflation, changes in interest or currency rates or adverse investor sentiment, public health issues, including widespread disease and virus epidemics or pandemics, war, terrorism or natural disasters, among others. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. The values of securities may fall due to factors affecting a particular issuer, industry or the securities market as a whole.
· Emerging markets and less developed countries risk - Emerging market and less developed countries generally are located in Asia, the Middle East, Eastern Europe, Central and South America and Africa. Investments in, or exposure to, securities that are tied economically to emerging market and less developed countries are subject to all of the risks of investments in, or exposure to, foreign securities, generally to a greater extent than in developed markets, among other risks. Investments in securities that are tied economically to emerging markets involve greater risk from economic and political systems that typically are less developed, and likely to be less stable, than those in more advanced countries. The Fund also will be subject to the risk of adverse foreign currency rate fluctuations. Emerging market and less developed countries may also have economies that are predominantly based on only a few industries or dependent on revenues from particular commodities. The risks of nationalization, expropriation or other confiscation of assets of non-U.S. issuers is also greater in emerging and less developed countries. As a result of these risks, investments in securities tied economically to emerging markets tend to be more volatile than investments in securities of developed countries.
· Foreign securities risk - Investments in, or exposure to, foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values, possible imposition of foreign withholding or other taxes on income payable on the securities, as well as adverse political, social and economic developments, such as political upheaval, acts of terrorism, financial troubles, sanctions or the threat of new or modified sanctions, or natural disasters. Many foreign securities markets, especially those in emerging market countries, are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the costs of trading in those markets is often higher than in U.S. securities markets. There may also be less publicly available information about issuers of foreign securities compared to issuers of U.S. securities. In addition, the economies of certain foreign markets may not compare favorably with the economy of the United States with respect to issues such as growth of gross national product, reinvestment of capital, resources and balance of payments position.
· Managed portfolio risk - As an actively managed portfolio, the Fund's portfolio manager(s) make decisions to buy and sell holdings in the Fund's portfolio. Because of this, the value of the Fund's investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, the Sub-Adviser's investment techniques could fail to achieve the Fund's investment objective or negatively affect the Fund's investment performance, or legislative, regulatory, or tax developments may affect the investment techniques available to the Sub-Adviser of the Fund. There is no guarantee that the investment objective of the Fund will be achieved.
· Concentration risk - The Fund may concentrate its investments in certain securities. To the extent that the Fund focuses on particular countries, regions, industries, sectors, issuers, types of investment or limited number of securities from time to time, the Fund may be subject to greater risks of adverse economic, business or political developments in the area of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.
· Large-capitalization investing risk - Large-capitalization stocks as a group could fall out of favor with the market, which may cause the Fund to underperform funds that focus on other types of stocks.
· Investment style risk - The returns from a certain investment style may be lower than the returns from the overall stock market. Growth stock prices frequently reflect projections of future earnings or revenues, and if earnings growth expectations are not met, their stock prices will likely fall, which may reduce the value of a Fund's investment in those stocks. Over market cycles, different investment styles may sometimes outperform other investment styles (for example, growth investing may outperform value investing).
· Non-diversification risk - The Fund is non-diversified, as defined by the 1940 Act, and as such may invest in the securities of a limited number of issuers and may invest a greater percentage of its assets in a particular issuer. Therefore, a decline in the market price of a particular security held by the Fund may affect the Fund's performance more than if the Fund were a diversified investment company.
3
· Depositary receipts risk - Depositary receipts, such as American depositary receipts ("ADRs"), global depositary receipts ("GDRs"), and European depositary receipts ("EDRs"), may be issued in sponsored or un-sponsored programs. They may be traded in the over-the-counter ("OTC") market or on a regional exchange, or may otherwise have limited liquidity. The prices of depositary receipts may differ from the prices of securities upon which they are based. In a sponsored program, a security issuer has made arrangements to have its securities traded in the form of depositary receipts. In an un-sponsored program, the issuer may not be directly involved in the creation of the program. Holders of un-sponsored depositary receipts generally bear all the costs of the facility. The depository usually charges fees upon deposit and withdrawal of the underlying securities, the conversion of dividends into U.S. dollars or other currency, the disposition of non-cash distributions, and the performance of other services. Depositary receipts involve many of the same risks as direct investments in foreign securities. These risks include: fluctuations in currency exchange rates, which are affected by international balances of payments and other economic and financial conditions; government intervention; and speculation. With respect to certain foreign countries, there is the possibility of expropriation or nationalization of assets, confiscatory taxation, political and social upheaval, and economic instability. Investments in depositary receipts that are exchange-traded or OTC may also subject the Fund to liquidity risk. This risk is enhanced in connection with OTC depositary receipts.
· Currency risk - Investments in foreign currencies, securities that trade in or receive revenues in foreign currencies, or derivatives that provide exposure to foreign currencies are subject to the risk that those currencies may decline in value or, in the case of hedging positions, that the currency may decline in value relative to the currency being hedged. Currency exchange rates can be volatile and may be affected by a number of factors, such as the general economics of a country, the actions (or inaction) of U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.
· Mid-capitalization and small-capitalization investing risk - The securities of mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements. Securities of such issuers may lack sufficient market liquidity to enable a Fund to effect sales at an advantageous time or without a substantial drop in price. Both mid-capitalization and small-capitalization companies often have narrower markets and more limited managerial and financial resources than larger, more established companies. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of a Fund's portfolio. Generally, the smaller the company size, the greater these risks become.
· Investing in China A Shares risk - Investments in Class A Shares of Chinese companies involve certain risks and special considerations not typically associated with investments in U.S. companies, such as greater government control over the economy, political and legal uncertainty, currency fluctuations or blockage, the risk that the Chinese government may decide not to continue to support economic reform programs and the risk of nationalization or expropriation of assets. Additionally, the Chinese securities markets are emerging markets subject to the special risks applicable to developing and emerging market countries described elsewhere in this prospectus.
· Investing through Stock Connect risk - The Fund may invest directly in China A shares through Stock Connect, and will be subject to the following risks: sudden changes in quota limitations, application of trading suspensions, differences in trading days between the PRC and Stock Connect, operational risk, clearing and settlement risk and regulatory and taxation risk.
· Warrants risk - If the price of the underlying stock does not rise above the exercise price before the warrant expires, the warrant generally expires without any value and the Fund loses any amount it paid for the warrant. As a result, investments in warrants may involve substantially more risk than investments in common stock. Warrants may trade in the same markets as their underlying stock; however, the price of the warrant does not necessarily move with the price of the underlying stock.
· Preferred stock risk - Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the company. Risks of preferred securities include (i) the ability of the issuer to defer or omit distributions for a stated period in its sole discretion, (ii) the potential for the security to lose value based on the credit worthiness of the issuer or its decision to defer distributions, (iii) the potential for the security to lose value in light of the increase in market interest rates (iv) the potential for the issuer to call (repay) the security or extend the term of the security, subject to the security's terms and issuer's discretion, which may impact the value of the security in light of prevailing market interest rates at that time, (v) the risk that the preferred securities may have a less liquid market than government securities or other equity securities issued by the issuer, and (vi) being subject to the decisions of voting shareholders of an issuer as preferred securities typically contain limited, or no, voting rights.
· Participation note risk - An investment in a participation note involves additional risks beyond the risks normally associated with a direct investment in the underlying security and a participation note's performance may differ from the underlying security's performance. Holders of participation notes do not have the same rights as an owner of the underlying stock and are subject to the credit risk of the issuer, and participation notes are privately issued and may be illiquid.
· Redemption risk - Large redemption activity could result in the Fund being forced to sell portfolio securities at a loss or before the Adviser or Sub-Adviser would otherwise decide to do so. Large redemption activity in the Fund may also result in increased expense ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher brokerage commissions, and other transaction costs.
4
· Liquidity risk - Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk arises, for example, from small average trading volumes, trading restrictions, or temporary suspensions of trading. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.
· Investments in IPOs risk - IPOs issued by unseasoned companies with little or no operating history are risky and highly volatile.
· China risk - The Chinese economy is generally considered an emerging market and can be significantly affected by economic and political conditions and policy in China and surrounding Asian countries. A relatively small number of Chinese companies represents a large portion of China's total market and thus may be more sensitive to adverse political or economic circumstances and market movements. The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others. Under China's political and economic system, the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership. In addition, expropriation, including nationalization, repatriation of capital, confiscatory taxation, political, economic or social instability or other developments could adversely affect and significantly diminish the values of the Chinese companies in which the Fund invests. The Chinese securities markets are subject to more frequent trading halts and low trading volume, resulting in substantially less liquidity and greater price volatility. These and other factors could have a negative impact on the Fund's performance and increase the volatility of an investment in the Fund.
· Commodity ETF risk - In addition to the risks described under "exchange-traded funds investing risk," the value of the Fund's investment in ETFs that invest in commodity-related securities may be affected by changes in overall market movements or factors affecting a particular industry or commodity and may fluctuate significantly over short periods for a variety of factors, such as drought, floods, weather, livestock disease, embargoes, war, insufficient storage capacity, tariffs and international economic, political and regulatory developments. Investments linked to the prices of commodities are considered speculative and may be more volatile than investments in other types of securities or instruments. The commodity markets are subject to temporary distortions or other disruptions due to a variety of factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention.
· Russia investment risk - During periods when sanctions are in place, such as the ongoing Russia/Ukraine war, there are risks related to holding positions located in or with ties to Russia. This may include, but is not limited to, the inability to dispose of securities in that country, the inability to settle securities transactions in that country, and the inability to repatriate currency from that country. Investments in sanctioned countries may be volatile, and the Fund and its pricing agent may have difficulty valuing such sanctioned securities. Absent sanctions prohibiting these investments, the Fund may invest a portion of its assets in securities issued by companies located in Russia. Because of the underdeveloped state of Russia's banking system and securities markets, settlement, clearing and registration of securities transactions are subject to significant risks. With the implementation of the National Settlement Depository ("NSD") in Russia as a recognized central securities depository, title to Russian equity securities is now based on the records of the NSD and not the registrars. Although the implementation of the NSD is generally expected to decrease the risk of loss in connection with recording and transferring title to securities, issues resulting in loss still might occur. In addition, issuers and registrars are still prominent in the validation and approval of documentation requirements for corporate action processing in Russia. Because the documentation requirements and approval criteria vary between registrars and/or issuers, there remain unclear and inconsistent market standards in the Russian market with respect to the completion and submission of corporate action elections. To the extent that the Fund suffers a loss relating to title or corporate actions relating to its portfolio securities, it may be difficult for the Fund to enforce its rights or otherwise remedy the loss.


Performance. The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns compared with those of a broad-based securities market index. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown. If such arrangements had not been in place, performance for those periods would have been lower. The Fund's past performance is not necessarily an indication of how the Fund will perform in the future.

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

Tax Information

The Fund expects to be treated as a partnership for U.S. federal income tax purposes, and does not expect to make regular distributions (other than in redemption of Fund shares) to shareholders, which generally are the participating insurance companies investing in the Fund through separate accounts of Jackson National or Jackson National NY and mutual funds owned directly or indirectly by such separate accounts. You should consult the prospectus of the appropriate separate account or description of the plan for a discussion of the U.S. federal income tax consequences to you of your contract, policy, or plan.

Payments to Broker-Dealers and Financial Intermediaries

If you invest in the Fund under a variable insurance contract or a plan that offers a variable insurance contract as a plan option through a broker-dealer or other financial intermediary (such as a financial institution), 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.
