Forward Looking Statements

This document includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  All statements, other than statements of historical facts, included in this document that address activities, events, plans, expectations, objectives or developments that VAALCO expects, believes or anticipates will or may occur in the future are forward-looking statements.  These statements may include statements related to: (i) the proposed Transaction, and its expected terms, timing and closing, including receipt of required approvals, if any, satisfaction of other customary closing conditions; and (ii) expectations regarding the listing of the common stock on the London Stock Exchange.  These statements are based on assumptions made by VAALCO based on its experience and perception of historical trends, current conditions, expected future developments and other factors it believes are appropriate in the circumstances.  Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond VAALCO's control.  These risks include, but are not limited to: the ability to obtain regulatory approvals (if any) in connection with the proposed arrangement; the ability to complete the proposed arrangement on the anticipated terms and timetable; the possibility that various closing conditions for the arrangement may not be satisfied or waived; and other risks described (i) under the caption "Risk Factors" in VAALCO's 2021 Annual Report on Form 10-K, filed with the Securities and Exchange Commission ("SEC") on March 11, 2022 and VAALCO's Second Quarter Quarterly Report on Form 10-Q, filed with the SEC on August 10, 2022; and (ii) in TransGlobe's 2021 Annual Report on Form 40-F, filed with the SEC on March 17, 2022. More information on potential factors that could affect VAALCO's or TransGlobe's ability to complete the proposed Transaction were included in the preliminary and the definitive proxy statements that VAALCO has filed with the SEC in connection with VAALCO's solicitation of proxies for the meeting of stockholders held to approve, among other things, the issuance of the consideration shares in connection with the proposed Transaction. There may be additional risks that VAALCO does not presently know, or that VAALCO currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect VAALCO's expectations, plans or forecasts of future events and views as of the date of this announcement. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. No obligation is being undertaken to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.
