EXPLANATORY NOTE
This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends the Annual Report on Form 10-K of Serina Therapeutics, Inc. (the “Company”) for the fiscal year ended December 31, 2025, as filed with the Securities and Exchange Commission (the “SEC”) on March 25, 2026 (the “Original 10-K”). Exhibit 23.1, Consent of Independent Registered Public Accounting Firm, with respect to the calendar year ended December 31, 2025, to the Original 10-K (the “Auditor Consent”) inadvertently contained an incorrect version of the Auditor Consent. This Amendment is being filed to include the correct version of the Auditor Consent.
Accordingly, Exhibit 23.1 in Part IV, Item 15 of the Original 10-K has been amended and restated in its entirety to reflect this change. The Company is also providing new certifications from its principal executive officer and principal financial officer as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended.
Except as described above, The Company has not modified or updated any disclosures contained in the Original 10-K. Accordingly, this Amendment does not reflect events occurring after the date of filing of the Original 10-K and therefore continues to speak only as of the date of the Original 10-K.
