JNL/JPMorgan Hedged Equity Fund

Class A

Class I

Before you invest, you may want to review the Fund's Prospectus, which contains more information about the Fund and its risks. You can find the Fund's Prospectus and other information about the Fund, including the Statement of Additional Information ("SAI") and most recent reports to shareholders, online at https://www.jackson.com/fund-literature.html. You can also get this information at no cost by calling 1-800-644-4565 (Annuity and Life Service Center), 1-800-599-5651 (NY Annuity and Life Service Center), 1-800-777-7779 (for contracts purchased through a bank or financial institution) or 1-888-464-7779 (for NY contracts purchased through a bank or financial institution), or by sending an email request to [email protected]. The current Prospectus and SAI, both dated April 27, 2026, as amended, are incorporated by reference into (which means they legally are a part of) this Summary Prospectus.

Investment Objective. The investment objective of the Fund is to seek to provide capital appreciation.

Expenses. This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund.

The expenses do not reflect the expenses of the variable insurance contracts or the separate account through which you indirectly invest in the Fund, whichever may be applicable, and the total expenses would be higher if they were included.

You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Expense 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. Also, this example does not reflect the expenses of the variable insurance contracts or the separate account through which you indirectly invest in the Fund, whichever may be applicable, and the total expenses would be higher if they were included. The table below shows the expenses you would pay on a $10,000 investment, assuming (1) 5% annual return; (2) redemption at the end of each time period; and (3) that the Fund operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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

Principal Investment Strategies. The Fund seeks to provide capital appreciation through participation in the broad equity markets while hedging overall market exposure relative to traditional long-only equity 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. The Fund seeks to achieve its investment objective by investing at least 80% of its assets in an "enhanced index," which primarily consist of common stocks of medium to large capitalization companies in the S&P 500 Index ("Index"). The enhanced index is a portfolio benchmarked to the Index, subject to constraints based on tracking error, individual name holdings, and sector. Because the Fund uses an "enhanced index" strategy, not all of the stocks in the Index, its primary benchmark, are included in the Fund, and the Fund's position in an individual stock may be overweighted or underweighted when compared to the Index. The Fund will also systematically purchase and sell exchange-traded put options and sell exchange-traded call options, employing an options overlay known as a "put/spread collar" strategy. The options may be based on the Index or on exchange-traded funds ("ETFs") that replicate the Index ("S&P 500 ETFs"). The combination of the diversified portfolio of equity securities, the downside hedge from long index put options, and the income from the short index call options is intended to provide the Fund with a portion of the returns associated with equity market investments while exposing investors to less risk than traditional long-only equity strategies. Specifically, the Fund seeks to provide a competitive risk-adjusted return over a full market cycle relative to the Index with lower volatility than traditional long-only equity strategies. The "put/spread collar" strategy is designed to provide a continuous market hedge for the portfolio (i.e., to minimize loss).

The Fund's combination of a diversified equity portfolio, with the "put/spread collar" options overlay strategy is designed to provide greater market protection than other equity investments, but may not always do so, particularly in rising equity markets when the Fund may underperform traditional equity strategies. In addition, as a result of the structure of the options overlay strategy, the Fund is not expected to provide market protection during times of low market volatility; during such periods, the Fund is expected to perform in line with broad equity markets.

The Fund may use derivatives, primarily futures contracts, to gain exposure to indexes or certain securities within indexes, to more effectively gain targeted equity exposure from its cash positions and to hedge the Fund's portfolio if it is unable to purchase or write the necessary options for its overlay strategy. To the extent the Fund invests in index futures with exposure to securities in the Index, it may have the effect of increasing the Fund's exposure to a relatively small number of securities, making the Fund more sensitive to the economic results of those securities.

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:

· Company risk - Investments in U.S. and/or foreign-traded equity securities may fluctuate more than the values of other types of securities in response to changes in a particular company's financial condition.
· Derivatives risk - Investments in derivatives, which are financial instruments whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices, can be highly volatile and may be subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. Derivatives also are subject to leverage risk, liquidity risk, interest rate risk, market risk, counterparty risk, and credit risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, interest rate or index. Gains or losses from derivatives can be substantially greater than the derivatives' original cost.
· 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.
2
· Exchange-traded funds investing risk - An investment in an ETF generally presents the following risks: (i) the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies; (ii) the risk that an ETF may fail to accurately track the market segment or index that underlies its investment objective; (iii) price fluctuation, resulting in a loss to the Fund; (iv) the risk that an ETF may trade at a discount to its net asset value; (v) the risk that an active market for an ETF's shares may not develop or be maintained; and (vi) the risk that an ETF may no longer meet the listing requirements of any applicable exchanges on which that ETF is listed. When the Fund invests in an ETF, shareholders of the Fund bear their proportionate share of the ETF's fees and expenses as well as their share of the Fund's fees and expenses.
· Investment style risk - The returns from a certain investment style may be lower than the returns from the overall stock market. Value stocks may not increase in price if other investors fail to recognize the company's value or the factors that are expected to increase the price of the security do not occur. Over market cycles, different investment styles may sometimes outperform other investment styles (for example, growth investing may outperform value investing).
· 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.
· 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.
· 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.
· 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.
· Mid-capitalization investing risk - The stocks of mid-capitalization companies can be more volatile and their shares can be less liquid than those of larger companies. Mid-capitalization companies may have limited product lines, markets or financial resources or may depend on the expertise of a few people and may be subject to more abrupt or erratic market movements than securities of larger, more established companies or the market averages in general. Securities of such issuers may lack sufficient market liquidity to effect sales at an advantageous time or without a substantial drop in price.
· Options risk - If the Fund buys an option, it buys a legal contract giving it the right to buy or sell a specific amount of the underlying instrument or futures contract on the underlying instrument at an agreed upon price typically in exchange for a premium paid by the Fund. If the Fund sells an option, it sells to another person the right to buy from or sell to the Fund a specific amount of the underlying instrument or futures contract on the underlying instrument at an agreed upon price typically in exchange for a premium received by the Fund. Options may be illiquid and the Fund may have difficulty closing out its position. The prices of options can be highly volatile and the use of options can lower total returns.
· 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.
· Stock risk - Stock markets may experience significant short-term volatility and may fall sharply at times. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets. The prices of individual stocks generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company's stock.
· Data science investment approach risk - The Fund relies on a proprietary data science enabled selection approach that utilizes proprietary techniques to process, analyze, and combine a wide variety of information, including the adviser's multi-decade history of proprietary fundamental research, company financial statements, and other relevant data sources, to forecast the financial prospects of each security and to assess key risks. There is no guarantee that the use of the Fund's proprietary data science approach will result in effective investment decisions for the Fund and, specifically to the extent the approach does not perform as designed or as intended, the Fund's strategy may not be successfully implemented and the Fund may lose value.


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 and an additional index that the Adviser believes more closely reflects the market segments in which the Fund invests. 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.

Effective April 27, 2020, the Fund was combined with the JNL/FAMCO Flex Core Covered Call Fund (the "Acquired Fund"), a series of Jackson Variable Series Trust, with the Fund as the surviving Fund. The performance shown is the Fund's historic performance and does not reflect the performance of the Acquired Fund.

Purchase and Redemption of Fund Shares

Only separate accounts of Jackson National Life Insurance Company ("Jackson National") or Jackson National Life Insurance Company of New York ("Jackson National NY") and series, including fund of funds, of registered investment companies in which either or both of those insurance companies invest may purchase shares of the Fund. You may invest indirectly in the Fund through your purchase of a variable annuity or life insurance contract issued by a separate account of Jackson National or Jackson National NY that invests directly, or through a fund of funds, in this Fund. Any minimum initial or subsequent investment requirements and redemption procedures are governed by the applicable separate account through which you invest indirectly.

This Fund serves as an underlying investment by insurance companies, affiliated investment companies, and retirement plans for funding variable annuity and life insurance contracts and retirement plans.

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.
