The holders' meeting relating to the warrants issued by Vista approved the amendments proposed by the Company

Mexico City, Mexico, October 4, 2022 - Vista Energy, S.A.B. de C.V. ("Vista" or the "Company") (BMV: VISTA, NYSE: VIST) announced to investors that today the meeting of holders ("Holders" and the "Holders' Meeting") of the warrants issued by Vista identified with the ticker symbol "VTW408A-EC001" (the "Warrants"), approved the amendments to the warrant indenture and the global certificate that covers such Warrants (the "Warrants Indenture") proposed by the Company, by means of which a cashless exercise mechanism was implemented that entitles the Holders to, in their sole discretion or at Vista's discretion (in the latter case, with respect to all outstanding warrants and without any further request, notice or communication required to or from Holders or any other person), obtain one Series A share representative of the capital stock of the Company ("Share") for each 31 Warrants owned (the "Exercise Ratio").

As a result, a maximum of 3,215,483 Shares will become outstanding, which represents approximately 90.32% less than the total number of Shares that would have otherwise become outstanding upon exercise of the Warrants under the original terms of the Warrant Indenture, or 33,226,667 Shares, assuming that the Warrants in their original terms would have been exercised in full.

In furtherance of the resolutions adopted at the Holders' Meeting, Vista and Monex Casa de Bolsa, S.A. de C.V., Monex Grupo Financiero, in its capacity as common representative of the Holders, entered into on the date hereof a first amendment and restatement of the Warrants Indenture reflecting the amendments described above. As a result of the execution of such amendment and restatement and the resolutions adopted by the Holders' Meeting, the Holders who so desire may exercise their exercise right on a cashless basis pursuant to the terms set forth in the Warrants Indenture, as amended, on or after October 10, 2022.

Vista has made available to Holders certain materials relating to their exercise right at https://vistaenergy.com/warrants. A template notice of exercise is available on that site, which the Holders may use to notify the Company of their intention to exercise their rights under the Warrants.
