**Investment Objective.** The investment objective of the Fund is to seek to track as closely as possible, before fees and expenses, the price and yield performance of the Morningstar<sup>®</sup> US Small-Mid Cap Moat Focus Index<sup>℠</sup>.

**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.

**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.

**Principal Investment Strategies.** The Fund seeks to invest under normal circumstances at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in the securities in the Morningstar<sup>®</sup> US Small-Mid Cap Moat Focus Index<sup>℠</sup> ("Index"). The Index is comprised of small- and medium-capitalization companies as defined by Morningstar, Inc. (the "Index provider''), that the Index Provider determines have sustainable competitive advantages based on a proprietary methodology that considers quantitative and qualitative factors ("wide and narrow moat companies"). The quantitative factors used by the Index Provider to identify competitive advantages currently include historical and projected returns on invested capital relative to cost of capital. The qualitative factors used by the Index Provider to identify competitive advantages currently include customer switching cost (i.e., the costs of customers switching to competitors), internal cost advantages, intangible assets (e.g., intellectual property and brands), network effects (i.e., whether products or services become more valuable as the number of customers grows) and efficient scale (i.e., whether the company effectively serves a limited market that potential rivals have little incentive to enter into).

Wide moat companies are those that the Index Provider believes will maintain their competitive advantage(s) for at least 20 years. Narrow moat companies are those that the Index Provider believes will maintain their competitive advantage(s) for at least 10 years. Wide and narrow moat companies are selected from the universe of companies represented in the Morningstar<sup>®</sup> US Small-Mid Cap Index<sup>℠</sup> (the "Parent Index"), a broad market index representing small- and medium-capitalization U.S. companies. For purposes of the Parent Index, the Index Provider considers those companies in the bottom 70%-90% of total U.S. market cap to be medium-capitalization companies and those companies in the bottom 90%-97% to be small-capitalization companies.

The Index targets a select group of equity securities of wide and narrow moat companies, which are those companies that, according to the Index Provider's equity research team ("Morningstar Research"), are attractively priced based on predefined factors as of each index review. A momentum signal is used to exclude 20% of the wide and narrow moat stocks in the Parent Index with the worst 12-month momentum based on the 12-month total return of each stock. Out of the companies in the Parent Index that Morningstar Research determines are wide or narrow moat companies and display 12-month momentum in the top 80%, Morningstar Research selects companies to be included in the Index as determined by the ratio of the issuer's common stock price to Morningstar Research's estimate of fair value. Morningstar Research 's fair value estimates are calculated using standardized, proprietary valuation models.

As of December 31, 2024, the Index included 109 securities of companies with a full market capitalization range of between approximately $2.26 billion and $67.91 billion and a weighted average full market capitalization of $20.22 billion. These amounts are subject to change. The Index is divided into two sub-portfolios that are reconstituted and rebalanced semi-annually on alternating quarters. Within each sub-portfolio, an equal weight is assigned to all constituents at rebalancing; constituent weights drift due to market movement until the next rebalance when they are reset to an equal weight.

The Fund may invest in financial futures, a type of derivative that may be used to obtain exposure to a variety of underlying assets, to provide liquidity for cash flows, to hedge dividend accruals or for other purposes that facilitate meeting the Fund's objective. The Fund's use of financial futures is intended to assist in seeking to replicate the investment performance of the Index.

The Fund employs a passive investment approach, called indexing, which attempts to replicate the investment performance of the Index through representative sampling. The Fund does not employ traditional methods of active investment management, which involves the buying and selling of securities based upon security analysis. The Fund attempts to replicate the Index by investing all or substantially all of its assets in the stocks that make up the Index.

The Fund will concentrate its investments in an industry or group of industries to the extent the Index that the Fund is designed to track is also concentrated. As of December 31, 2024, the consumer discretionary sector represented a significant portion of the Index.

Although the Fund is diversified, the Fund may, at times, be invested in a non-diversified manner to the extent that the Index is also invested in a non-diversified manner.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;• *License termination risk* **–** The Fund may rely on licenses from a third party (licensor) that permit the Fund to use that party's intellectual property in connection with
 the Fund's name and/or investment strategies. The license may be terminated by the licensor, and as a result the Fund may lose its ability to use the licensed name or strategy, or receive important data from the licensor. Accordingly, a
 license may have a significant effect on the future operation of the Fund, including the need to change the investment strategy.

&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;• *Passive investment risk* –
 The Fund is not actively managed. Unlike with an actively managed fund, the Fund does not use techniques or defensive strategies designed to lessen the effects of market volatility or to reduce the impact of periods of market decline. This
 means that, based on market and economic conditions, the Fund's performance could be lower than actively managed funds that realign their portfolios more frequently based on the real-time market trends.

&nbsp;&nbsp;&nbsp;&nbsp;• *Index investing risk –* The
 Fund's indexing strategy does not attempt to manage volatility, use defensive strategies, or reduce the effects of any long-term periods of poor stock performance. Should the Fund engage in index sampling, the performance of the securities
 selected will not provide investment performance tracking that of the Index. Fund performance may not exactly correspond with the performance of the relevant index for a number of reasons, including, but not limited to: the timing of
 purchases and redemptions of the Fund's shares, changes in the composition of the index, and the Fund's expenses. Certain regulatory limitations, such as fund diversification requirements, may limit the ability of the Fund to completely
 replicate an index. Although, the Fund may, at times, be invested in a non-diversified manner to the extent that the Index is also invested in a non-diversified manner.

&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;• *Sector risk* – Companies
 with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. For example,
 this may be due to changes in the regulatory or competitive environment or changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund's performance may be
 more susceptible to any developments which affect those sectors emphasized by the Fund. In addition, the Fund could underperform other funds investing in similar sectors or comparable benchmarks because of the investment manager's choice of
 securities within such sector.

&nbsp;&nbsp;&nbsp;&nbsp;• *Consumer discretionary risk* – If the Fund invests a significant portion of its assets in issuers in the consumer discretionary sector of the market, the Fund may be more affected by events influencing the consumer discretionary sector than a fund that is more
 diversified across numerous sectors. An investment in issuers in the consumer discretionary sector can be significantly affected by the performance of the overall economy, interest rates, competition and consumer confidence. Success of these
 companies can depend heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, products of consumer discretionary companies.

&nbsp;&nbsp;&nbsp;&nbsp;• *Tracking error risk* –
 Tracking error is the divergence of the Fund's performance from that of the Index. The Fund's return may not track the return of the Index for a number of reasons. Tracking error may occur because of differences between the securities and
 other instruments held in the Fund's portfolio and those included in the Index, pricing differences, differences in transaction costs, the Fund's holding of uninvested cash, differences in timing of the accrual of or the valuation of
 dividends or interest, tax gains or losses, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other
 unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not. However, the Fund may be required to deviate its investments from the securities and relative weightings of the
 Index to comply with the 1940 Act, as amended to meet the issuer diversiﬁcation requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, or as a result of local market restrictions, or other
 legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Investment Adviser and its afﬁliates.

&nbsp;&nbsp;&nbsp;&nbsp;• *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.

<br>**Performance.** Performance for the Fund has not been included because the Fund has less than one full calendar year of operations.

#### 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.
