("Corebridge"), the ultimate parent company of SunAmerica Asset Management, LLC ("SunAmerica"), and Venerable Holdings, Inc. ("Venerable") announced that they had entered into a definitive agreement pursuant to which Venerable would acquire SunAmerica (the "Transaction"). The Transaction closed on January 1, 2026.

Following the completion of the Transaction, SunAmerica became a wholly-owned subsidiary of Venerable.

In connection with SunAmerica's change of control, the Board of Trustees (the "Board") of SunAmerica Series Trust (the "Trust") appointed Directed Services LLC, an affiliate of Venerable, as the new distributor, replacing Corebridge Capital Services, Inc., the prior distributor affiliated with Corebridge.

Additionally, the Board appointed Mr. Timothy W. Brown as a new trustee of the Trust, effective January 1, 2026. Mr. Brown is considered an "interested person" of the Trust due to his affiliation with Venerable.

The Transaction did not result in any changes to the portfolio management of the Portfolios, nor did it affect the Portfolios' investment objectives or policies.

Effective immediately, the following changes are made to the Prospectus and/or SAI, as applicable:

*Address Changes* 

All references to the address for each of the Trust and SunAmerica are changed to the following: One World Trade Center, 285 Fulton Street, Suite 49M, New York, NY 10007.
