Report of Independent Registered Public Accounting Firm

The Board of Trustees of Transamerica Series Trust

We have examined management's assertion, included in the accompanying Management Statement Regarding Compliance With Certain Provisions of the Investment Company Act of 1940, that Transamerica Series Trust (the "Trust") (refer to Appendix A for fund listing) complied with the requirements of subsections (b) and (c) of Rule 17f-2 under the Investment Company Act of 1940 ("the Act") as of June 30, 2025. Management is responsible for its assertion about compliance with the requirements of subsections (b) and (c) of Rule 17f-2 of the Act (the specified requirements). Our responsibility is to express an opinion on management's assertion about the Funds' compliance with the specified requirements based on our examination.

Our examination was conducted in accordance with the attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether management's assertion about compliance with the specified requirements is fairly stated, in all material respects. An examination involves performing procedures to obtain evidence about whether management's assertion is fairly stated, in all material respects. The nature, timing, and extent of the procedures selected depend on our judgment, including an assessment of the risks of material misstatement of management's assertion, whether due to fraud or error. We believe that the evidence we obtained is sufficient and appropriate to provide a reasonable basis for our opinion.

Included among our procedures were the following tests performed as of June 30, 2025, and with respect to agreement of security purchases and sales, for the period from November 1, 2024 (the immediate date after our last examination) through June 30, 2025:

• Confirmation of all securities of the Funds in book entry form held by the Depository Trust Company and
International Depositories;

• Reconciliation of all such securities of the Funds between the books and records of the Funds and the
Custodian;

• Review of the reconciliation procedures performed by the Custodian at an omnibus level between the Depository
Trust Company and International Depositories and the books and records of the Custodian; and

• Agreement of the settlement of a sample of 25 security purchases and 25 security sales, for Transamerica MSCI
EAFE Index VP, and a sample of 25 security purchases and 25 security sales or maturities, for Transamerica S&P 500 Index VP, since our last report from the books and records of the Funds to Custodian bank statements.

We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on the Funds' compliance with specified requirements.

In our opinion, management's assertion that Transamerica Series Trust complied with the requirements of subsections (b) and (c) of Rule 17f-2 of the Act as of June 30, 2025, with respect to securities reflected in the investment account of the Funds is fairly stated, in all material respects.

This report is intended solely for the information and use of management and the Board of Trustees of Transamerica Series Trust and the Securities and Exchange Commission and is not intended to be and should not be used by anyone other than these specified parties.
