Pursuant to a Master Advisory Fee Waiver Agreement, SunAmerica Asset Management, LLC (”SunAmerica”) contractually agreed to waive a portion of its advisory fee for the Portfolio so that the advisory fee on average daily net assets payable to SunAmerica equals 0.73% on the first $250 million, 0.67% on the next $250 million, and 0.58% above $500 million. This agreement may be modified or discontinued prior to July 31, 2027 only with the approval of the Board of Trustees (the “Board”) of Seasons Series Trust (the “Trust”), including a majority of the trustees of the Board who are not “interested persons” of the Trust as defined in the Investment Company Act of 1940, as amended.
Expense Example
This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same (except that the Example incorporates any applicable fee waiver and/or expense limitation arrangements for only the first year). The Example does not reflect charges imposed by the Variable Contract. If the Variable Contract fees were reflected, the expenses would be higher. See the Variable Contract prospectus for information on such charges. Although your actual costs may be higher or lower, based

Portfolio Turnover
The Portfolio 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 portfolio operating expenses or in the Example, affect the Portfolio’s performance.
During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 55% of the average value of its portfolio.
Principal Investment Strategies of the Portfolio
The Portfolio attempts to achieve its investment goal by investing, under normal circumstances, at least 80% of net assets in equity securities of large capitalization companies selected through a growth strategy.Large-cap companies will generally include companies whose market capitalizations are equal to or greater than the market capitalization of the smallest company in the Russell 1000® Index during the most recent 12-month period. As of May 31, 2026, the market capitalization range of the companies in the Russell 1000® Index was between approximately $17,107.0 million and $5.15 trillion. The third-party growth-style indices currently used to identify growth companies are the Russell 3000® Growth Index and the MSCI All Country World Investible Market Growth Index, although the Portfolio may change the referenced indexes without prior notice. For purposes of the Portfolio’s 80% investment policy, a company is considered to be a growth company if it: (i) issues securities that are represented in a third-party growth-style index; or (ii) is above the relevant equity market median in at least two “growth metrics” similar to those commonly used by third-party growth index providers or third-party vendors in growth classifications, such as earnings growth, price‑to‑earnings or sales growth, among others. The third-party value-style indices currently used to identify value companies are the Russell 3000® Value Index and the MSCI ACWI IMI Value Index, although the Portfolio may change the referenced indexes without prior notice.
The Portfolio may invest in foreign securities, including emerging market securities. The Portfolio may invest in equity securities of medium-capitalization companies and
short-term investments (up to 20%). The short-term investments in which the Portfolio may invest in the aggregate include, but are not limited to, money market funds, certificates of deposit, savings association obligations, commercial paper, U.S. government obligations, corporate bonds and notes, and repurchase agreements.
The Portfolio is non-diversified, which means that it may invest its assets in a smaller number of issuers than a diversified portfolio. The Portfolio may at times invest significantly in certain sectors, such as the information technology sector.
The Portfolio is actively managed by two subadvisers and, to balance the risks of the Portfolio, a portion of the Portfolio is passively managed by a third subadviser. The passively managed portion of the Portfolio invests in all or substantially all of the stocks included in the S&P 500® Growth Index (the “Index”), a strategy known as “replication.” The subadviser may, however, utilize an “optimization” strategy in circumstances in which replication is difficult or impossible, such as if the Portfolio has low asset levels and cannot replicate, to reduce trading costs or to gain exposure to securities that the Portfolio cannot access directly. The goal of optimization is to select stocks which ensure that characteristics such as industry weightings, average market capitalizations and fundamental characteristics (e.g., price-to-book, price-to-earnings, debt-to-asset ratios and dividend yields) closely approximate those of the Index. Stocks not in the Index may be held before or after changes in the composition of the Index or if they have characteristics similar to stocks in the Index. The subadviser may also invest the Portfolio’s assets in investments with economic characteristics that are comparable to the economic characteristics of securities included in the Index, including derivatives, such as contracts for difference.
Principal Risks of Investing in the Portfolio
As with any mutual fund, there can be no assurance that the Portfolio’s investment goal will be met or that the net return on an investment in the Portfolio will exceed what could have been obtained through other investment or savings vehicles. Shares of the Portfolio are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation. If the value of the assets of the Portfolio goes down, you could lose money.
The following is a summary of the principal risks of investing in the Portfolio.
Equity Securities Risk. The Portfolio invests principally in equity securities and is therefore subject to the risk that
Seasons Series Trust

SA Multi-Managed Large Cap Growth Portfolio
stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day-to-day and may decline significantly.
Large-Cap Companies Risk. Large-cap companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Portfolio’s value may not rise as much as the value of portfolios that emphasize smaller companies. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rate of successful smaller companies, particularly during extended periods of economic expansion.
Growth Stock Risk. Growth stocks may lack the dividend yield associated with value stocks that can cushion total return in a bear market. Also, growth stocks normally carry a higher price/earnings ratio than many other stocks. Consequently, if earnings expectations are not met, the market price of growth stocks will often decline more than other stocks.
Foreign Investment Risk. The Portfolio’s investments in the securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the Portfolio invests may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the Portfolio’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability and other conditions or events (including, for example, military confrontations, war, terrorism, sanctions, disease/virus, outbreaks and epidemics). Lack of relevant data and reliable public information may also affect the value of these securities. The risks of foreign investments are heightened when investing in issuers in emerging market countries.
Emerging Markets Risk. Risks associated with investments in emerging markets may include: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasive corruption and crime; exchange rate volatility; inflation, deflation or currency devaluation; violent military or political conflicts; confiscations and other government restrictions by the United States or other governments; and government instability. As a result, investments in emerging market securities tend to be more volatile than investments in developed countries.
Failure to Match Index Performance Risk. The ability of the Portfolio to match the performance of the Index may be affected by, among other things, changes in securities
markets, the manner in which performance of the Index is calculated, changes in the composition of the Index, the amount and timing of cash flows into and out of the Portfolio, commissions, portfolio expenses, and any differences in the pricing of securities by the Portfolio and the Index. When the Portfolio employs an “optimization” strategy, the Portfolio is subject to an increased risk of tracking error, in that the securities selected in the aggregate for the Portfolio may perform differently than the underlying index.
Index Risk. The passively-managed index portion of the Portfolio generally will not sell securities in its portfolio and buy different securities over the course of a year other than in conjunction with changes in its target index, even if there are adverse developments concerning a particular security, company or industry. As a result, you may suffer losses that you would not experience with an actively-managed mutual fund.
Mid-Cap Companies Risk. Securities of mid-cap companies are usually more volatile and entail greater risks than securities of large companies.
Affiliated Fund Rebalancing Risk. The Portfolio may be an investment option for other mutual funds for which SunAmerica serves as investment adviser that are managed as “funds of funds.” From time to time, the Portfolio may experience relatively large redemptions or investments due to the rebalancing of a fund of funds. In the event of such redemptions or investments, the Portfolio could be required to sell securities or to invest cash at a time when it is not advantageous to do so.
Sector Risk. Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the possibility that a certain sector may underperform other sectors or the market as a whole. As the Portfolio allocates more of its portfolio holdings to a particular sector, the Portfolio’s performance will be more susceptible to any economic, business or other developments which generally affect that sector.
Information Technology Sector Risk. There are numerous risks and uncertainties involved in investing in the information technology sector. Historically, the prices of securities in this sector have tended to be volatile. If the Portfolio invests primarily in information technology-related issuers, it bears an additional risk that economic events may affect a substantial portion of the Portfolio’s investments. In addition, at times equity securities of technology-related issuers may underperform relative to other sectors. The information technology sector includes companies from various industries, including internet, computer hardware, software, semiconductors,

telecommunications, electronics, aerospace and defense, health care equipment and biotechnology, among others.
Short-Term Investments Risk. Short-term investments include, but are not limited to, money market funds, certificates of deposit, savings association obligations, commercial paper, U.S. government obligations, corporate bonds and notes, and repurchase agreements. Short-term investments may have lower yields than longer-term investments. Substantial holdings in short-term investments could cause the Portfolio to miss investment opportunities during periods of rising markets, and the Portfolio may be less likely to achieve its investment objective.
Management Risk. The Portfolio is subject to management risk because it is an actively-managed investment portfolio. The Portfolio’s portfolio managers apply investment techniques and risk analyses in making investment decisions, but there can be no guarantee that these decisions or the individual securities selected by the portfolio managers will produce the desired results.
Market Risk. The Portfolio’s share price or the market as a whole can decline for many reasons or be adversely affected by a number of factors, including, without limitation: weakness in the broad market, a particular industry, or specific holdings; adverse social, political, regulatory or economic developments in the United States or abroad; changes in investor psychology; technological disruptions; heavy institutional selling; military confrontations, war, terrorism, sanctions and other armed conflicts; trade wars and similar conflicts; disease/virus outbreaks and epidemics; recessions; taxation and international tax treaties; currency, interest rates and price fluctuations; and other conditions or events. In addition, the adviser’s or a subadviser’s assessment of securities held in the Portfolio may prove incorrect, resulting in losses or poor performance even in a rising market.
Non-Diversification Risk. The Portfolio is organized as a “non-diversified” fund. A non-diversified fund may invest a larger portion of assets in the securities of a single company than a diversified fund. By concentrating in a smaller number of issuers, the Portfolio’s risk may be increased because the effect of each security on the Portfolio’s performance is greater.
Issuer Risk. The value of a security may decline for a number of reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.
Derivatives Risk. A derivative is any financial instrument whose value is based on, and determined by, another security, index, rate or benchmark (i.e., stock options,
futures, caps, floors, etc.). To the extent a derivative contract is used to hedge another position in the Portfolio, the Portfolio will be exposed to the risks associated with hedging described below. To the extent an option, futures contract, swap, or other derivative is used with the goal of enhancing return, rather than as a hedge, the Portfolio will be directly exposed to the risks of the contract. Unfavorable changes in the value of the underlying security, index, rate or benchmark may cause sudden losses. Gains or losses from the Portfolio’s use of derivatives may be substantially greater than the amount of the Portfolio’s investment. Certain derivatives have the potential for unlimited loss. Derivatives are also associated with various other risks, including market risk, leverage risk, hedging risk, counterparty risk, valuation risk, regulatory risk, illiquidity risk and interest rate fluctuations risk. The primary risks associated with the Portfolio’s use of derivatives are market risk, counterparty risk and hedging risk.
Foreign Currency Risk. The value of the Portfolio’s foreign investments may fluctuate due to changes in currency exchange rates. A decline in the value of foreign currencies relative to the U.S. dollar generally can be expected to depress the value of the Portfolio’s non-U.S. dollar-denominated securities.
Performance Information
The following bar chart illustrates the risks of investing in the Portfolio by showing changes in the Portfolio’s performance from calendar year to calendar year and the table compares the Portfolio’s average annual returns to those of the S&P 500® Index (a broad-based securities market index) and the S&P 500® Growth Index, which is relevant to the Portfolio because it has characteristics similar to the Portfolio’s investment strategies. Fees and expenses incurred at the contract level are not reflected in the bar chart or table. If these amounts were reflected, returns would be less than those shown. Of course, past performance is not necessarily an indication of how the Portfolio will perform in the future.
BlackRock Investment Management, LLC (“BlackRock”) assumed subadvisory duties of the passively managed portion of the Portfolio effective April 30, 2025. Prior to that, SunAmerica managed that portion of the Portfolio. Effective May 1, 2019, Morgan Stanley Investment Management Inc. (“MSIM”) assumed management of a portion of the Portfolio.

Purchases and Sales of Portfolio Shares
Shares of the Portfolios may only be purchased or redeemed through Variable Contracts offered by the separate accounts of participating life insurance companies and by other portfolios of the Trust and SunAmerica Series Trust. Shares of a Portfolio may be purchased and redeemed each day the New York Stock Exchange is open, at the Portfolio’s net asset value determined after receipt of a request in good order.
The Portfolios do not have any initial or subsequent investment minimums. However, your insurance company may impose investment or account minimums. Please consult the prospectus (or other offering document) for your Variable Contract which may contain additional information about purchases and redemptions of Portfolio shares.

Tax Information
The Portfolios will not be subject to U.S. federal income tax so long as they qualify as regulated investment companies and distribute their income and gains each year to their shareholders. However, contractholders may be subject to U.S. federal income tax (and a U.S. federal Medicare tax of 3.8% that applies to net investment income, including taxable annuity payments, if applicable) upon withdrawal from a Variable Contract. Contractholders should consult the prospectus (or other offering document) for the Variable Contract for additional information regarding taxation.
Payments to Broker-Dealers and
Other Financial Intermediaries
The Portfolios are not sold directly to the general public but instead are offered as an underlying investment option for Variable Contracts and to other portfolios of the Trust and SunAmerica Series Trust. A Portfolio and its related companies may make payments to the sponsoring insurance company (or its affiliates) for distribution and/or other services. These payments may create a conflict of interest as they may be a factor that the insurance company considers in including a Portfolio as an underlying investment option in the Variable Contract. The prospectus (or other offering document) for your Variable Contract may contain additional information about these payments.
