EXPLANATORY NOTE
On March 16, 2026, VAALCO Energy, Inc. (“Vaalco”) filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “Original Form 10-K”). The purpose of this Amendment No. 1 to the Original Form 10-K (this “Amendment No. 1”) is to provide an updated Consent of Netherland, Sewell & Associates, Inc., Vaalco’s independent petroleum engineer, to correct a typographical error regarding one of the dates included in the original Consent of Netherland, Sewell & Associates, Inc. filed with the Original Form 10-K. No other items or disclosures in the Original Form 10-K are being amended and this Amendment No. 1 does not modify, amend or update in any way the financial or other disclosures as presented in the Original Form 10-K. This Amendment No. 1 does not reflect any events that may have occurred subsequent to the filing of the Original Form 10-K.
In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Amendment No. 1 contains new certifications by Vaalco’s principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act, which are attached hereto; however, because this Amendment No. 1 does not include financial statements and does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of such certifications have been omitted. Similarly, because this Amendment No. 1 does not include financial statements, certifications under Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002) have been omitted.
