New Subadvisory Arrangements and Investment Strategy Change

On August 23, 2024, the Board of Trustees of the Trust (the Board) approved: (i) a new subadvisory agreement with Putnam Investment Management, LLC to serve as a subadviser to the Portfolio alongside Jennison Associates LLC, J.P. Morgan Investment Management Inc., Massachusetts Financial Services Company and PGIM Quantitative Solutions LLC; (ii) certain revisions to the principal investment strategy of the Portfolio; and (iii) revisions to the Portfolio's management fee rate schedule, which are expected to lower the Portfolio's effective management fee. These changes are expected to become effective on or about January 13, 2025.

In addition, the Board approved, subject to shareholder approval, the reorganization of the AST Emerging Markets Equity Portfolio, also a series of the Trust, into the Portfolio (the Reorganization). The above changes are contingent on approval of the Reorganization by shareholders of the AST Emerging Markets Equity Portfolio.

If the Reorganization is approved, more detailed information will be provided in a supplement to the Portfolio's Summary Prospectus, Prospectus and SAI in December 2024.

THIS SUPPLEMENT SHOULD BE READ AND RETAINED FOR FUTURE REFERENCE.
