**NOTES TO PORTFOLIO OF INVESTMENTS *— March 31, 2026 — (unaudited)***

------

**Note 1 — Security Valuation**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In accordance with the authoritative guidance on fair value measurements and disclosures under U.S. generally accepted accounting principles ("GAAP"), the Portfolios disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure the fair value. In accordance with GAAP, fair value is defined as the price that the Portfolios would receive upon selling an asset or transferring a liability in a timely transaction to an independent third party in the principal or most advantageous market. GAAP establishes a three-tier hierarchy to provide more transparency around the inputs used to measure fair value and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tiers are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Level 1 — Unadjusted quoted prices in active markets for identical securities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Level 2 — Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, referenced indices, quoted prices in inactive markets, adjusted quoted prices in active markets, adjusted quoted prices on foreign equity securities that were adjusted in accordance with pricing procedures adopted by the Board of Trustees (the "Board")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Level 3 — Significant unobservable inputs (includes inputs that reflect the Portfolios' own assumptions about the assumptions market participants would use in pricing the security, developed based on the best information available under the circumstances)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Changes in valuation techniques may result in transfers in or out of an investment's assigned Level within the hierarchy. The methodology used for valuing investments is not necessarily an indication of the risk associated with investing in those investments and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to each security.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is recently issued and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The summary of the Portfolios' assets and liabilities classified in the fair value hierarchy as of March 31, 2026, is reported on a schedule at the end of each Portfolio's Portfolio of Investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The net asset value ("NAV") of each Portfolio is determined based upon the NAV of its corresponding Master Fund.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Board must determine fair value in good faith for portfolio holdings for which market quotations are not readily available or are unreliable. The Board has designated SAAMCo as the valuation designee ("Valuation Designee") to perform the fair valuation determinations relating to any or all portfolio investments. SAAMCo, as the Valuation Designee, has adopted policies and procedures and has established a pricing review committee to determine the fair value of the designated portfolio holdings on its behalf.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Master Funds:** Each Master Fund is a series of AFIS. All portfolio securities of funds managed by Capital Research and Management Company ("Capital Research") are valued, and the NAV per share for each share class are determined, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The AFIS investment adviser values the AFIS investments at fair value as defined by U.S. GAAP. The net asset value of per share is calculated once daily as of the close of regular trading on the New York Stock Exchange, normally 4 p.m. New York time, each day the New York Stock Exchange is open.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Methods and inputs — The AFIS investment adviser uses the following methods and inputs to establish the fair value of each fund's assets and liabilities. Use of particular methods and inputs may vary over time based on availability and relevance as market and economic conditions evolve.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Equity securities, including depositary receipts, are generally valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market on which the security trades. The value of an underlying fund is based on its reported net asset value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Fixed-income securities, including short-term securities, are generally valued at evaluated prices obtained from third-party pricing vendors. Vendors value such securities based on one or more of the inputs described in the following table. The table provides examples of inputs that are commonly relevant for valuing particular classes of

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**NOTES TO PORTFOLIO OF INVESTMENTS *— March 31, 2026 — (unaudited) — (continued)***

------

fixed-income securities in which the funds are authorized to invest. However, these classifications are not exclusive and any of the inputs may be used to value any other class of fixed-income security.

---

| | |
|:---|:---|
| **Fixed-income class** | **Examples of standard inputs** |
| All | Benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new <br> issues, spreads and other relationships observed in the markets among comparable securities; and <br> proprietary pricing models such as yield measures calculated using factors such as cash flows, <br> financial or collateral performance and other reference data (collectively referred to as "standard <br> inputs")<br>|
| Corporate bonds, notes & loans; convertible securities | Standard inputs and underlying equity of the issuer |
| Bonds & notes of governments & government agencies | Standard inputs and interest rate volatilities |
| Mortgage-backed; asset-backed obligations | Standard inputs and cash flows, prepayment information, default rates, delinquency and loss <br> assumptions, collateral characteristics, credit enhancements and specific deal information<br>|
| Municipal securities | Standard inputs and, for certain distressed securities, cash flows or liquidation values using a net <br> present value calculation based on inputs that include, but are not limited to, financial statements and <br> debt contracts<br>|

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Securities with both fixed-income and equity characteristics, or equity securities traded principally among fixed-income dealers, are generally valued in the manner described for either equity or fixed-income securities, depending on which method is deemed most appropriate by the AFIS investment adviser. The Capital Group Central Corporate Bond Fund ("CCBF"), a fund within the Capital Group Central Fund Series II, and Capital Group Central Cash Fund ("CCF"), a fund within the Capital Group Central Fund Series (collectively the "Central Funds"), are each valued based upon a floating net asset value, which fluctuates with changes in the value of each fund's portfolio securities. The underlying securities are valued based on the policies and procedures in the Central Funds' statements of additional information. The State Street Institutional U.S. Government Money Market Fund held by the managed risk funds is managed to maintain a $1.00 net asset value per share. The net asset value of each share class of each managed risk fund is calculated based on the reported net asset values of the underlying funds in which each fund invests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Exchange-traded options and futures are generally valued at the official closing price for options and official settlement price for futures on the exchange or market on which such instruments are traded, as of the close of business on the day such instruments are being valued. Forward currency contracts are valued based on the spot and forward exchange rates obtained from third-party pricing vendors. Swaps and over-the-counter (OTC) options are generally valued using evaluated prices obtained by third-party pricing vendors who calculate these values based on market inputs that may include the yields of the indices referenced in the instrument and the relevant curve, dealer quotes, default probabilities and recovery rates, exchange rates, implied option volatilites, and terms of the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Securities and other assets for which representative market quotations are not readily available or are considered unreliable by the AFIS investment adviser are fair valued as determined in good faith under fair value guidelines adopted by AFIS investment advisor and approved by the AFIS board of trustees as further described. The AFIS investment adviser follows fair valuation guidelines, consistent with U.S. Securities and Exchange Commission rules and guidance, to consider relevant principles and factors when making fair value determinations. The AFIS investment adviser considers relevant indications of value that are reasonably and timely available to it in determining the fair value to be assigned to a particular security, such as the type and cost of the security, restrictions on resale of the security, relevant financial or business developments of the issuer, actively traded similar or related securities, dealer or broker quotes, conversion or exchange rights on the security, related corporate actions, significant events occurring after the close of trading in the security, and changes in overall market conditions. In addition, the closing prices of equity securities and futures that trade in markets outside U.S. time zones may be adjusted to reflect significant events that occur after the close of local trading but before the net asset value of each share class of each fund is determined. Fair valuations of investments that are not actively trading involve judgment and may differ materially from valuations that would have been used had greater market activity occurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Processes and structure — The AFIS board of trustees has designated the AFIS investment adviser to make fair value determinations, subject to board oversight. The AFIS investment adviser has established a Joint Fair Valuation Committee (the "Committee") to administer, implement and oversee the fair valuation process, and to make fair value decisions. The Committee regularly reviews its own fair value decisions, as well as decisions made under its standing instructions to the AFIS investment adviser's valuation team. The Committee reviews changes in fair value measurements from period to period, pricing vendor information and market data, and may, as deemed appropriate, update the fair valuation guidelines to better reflect the results of back testing and address new or evolving issues. Pricing decisions, processes and controls over security valuation are also subject to additional internal reviews facilitated by the AFIS investment adviser's global risk management group. The Committee reports any changes to the fair valuation guidelines to the AFIS board of trustees. The AFIS board and audit committee also regularly review reports that describe fair value determinations and methods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additional information is available in the Trust's Annual and Semiannual financial statements which may be obtained without charge from the EDGAR database on the Securities and Exchange Commission's website at www.sec.gov.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SunAmerica Series Trust has five feeder funds which invest exclusively in Shares of the American Funds—Class 1 Shares of Asset Allocation Fund, Global Growth Fund, Growth Fund, and Growth-Income Fund and Class P1 Shares of Managed Risk Growth-Income Fund.
