Notice of Annual Meeting of Shareholders

TO THE SHAREHOLDERS OF VAALCO ENERGY, INC.:

The 2026 Annual Meeting of Shareholders of Vaalco Energy, Inc. (the "Company") will be held at the Hilton Houston Westchase, 9999 Westheimer Road, Houston, Texas 77042 on Thursday, June 4, 2026, at 9:00 a.m. Central Time (the "Annual Meeting"). We intend to hold our annual meeting in person.

THE ANNUAL MEETING IS BEING HELD:

1. To elect five directors, each for a term of one year;
2. To ratify the appointment of KPMG LLP as the Company's independent registered public accounting firm for 2026;
3. To approve, on an advisory basis, the compensation of our named executive officers;
4. To approve an amendment to the VAALCO Energy, Inc. 2020 Long Term Incentive Plan to increase the number of shares reserved for issuance, revise share reservation and recycling rules, and extend the term of the plan; and
5. To transact such other business as may properly come before the Annual Meeting or any adjournments, postponements, or recesses thereof.

These proposals are described in the accompanying proxy materials. You will be able to vote at the Annual Meeting, or any adjournment, postponement or recess thereof, only if you were a shareholder of record at the close of business on April 10, 2026.

We are providing our shareholders access to our proxy materials over the internet. To do this, we are mailing a Notice of Internet Availability of Proxy Materials (the "Notice") on or about April 24, 2026. The Notice contains instructions on how to access those documents over the internet, and how to request a paper copy of our proxy materials.

Shareholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. Shareholders who receive future proxy materials by email will save us the cost of printing and mailing documents and will reduce the impact of meetings of shareholders on the environment. A shareholder's election to receive proxy materials by email will remain in effect until the shareholder terminates that election.

By Order of the Board of Directors,

Andrew L. Fawthrop
Chair of the Board
Houston, Texas
