Vista Argentina Announces its Participation as Shareholder in the Vaca Muerta Sur Project.

Mexico City, December 16, 2024 - Vista Energy, S.A.B. de C.V. (“Vista”) (NYSE: VIST in the New York Stock Exchange; BMV: VISTA in the Mexican Stock Exchange) announced today the participation of its subsidiary Vista Energy Argentina S.A.U. (“Vista Argentina”) in the Vaca Muerta Sur Project, to be developed jointly with YPF S.A., Pampa Energía S.A. and Pan American Sur S.A. (collectively, the “Shareholders”) through a newly created company called VMOS S.A. (“VMOS”).

In this regard, we hereby inform that the Board of Directors of VMOS, at its meeting held on December 13, 2024, unanimously approved the construction of the Vaca Muerta Sur crude oil export pipeline (the “Project”). It is expected that the Project will have an extension of 437 kilometers, with a loading and unloading terminal with interconnected monobuoys, and a tank and storage yard.

We expect that the Project will allow for the transportation of up to 550,000 barrels of crude oil per day (“bbl/d”) at commercial operation, which can be increased to 700,000 bbl/d, if required (the “Project Expansion”). According to the Project’s construction schedule, commercial operations are expected to commence during the second half of 2027. The Shareholders have committed approximately 275,000 bbl/d of capacity and VMOS has granted options to Chevron Argentina S.R.L., Pluspetrol S.A. and Shell Argentina S.A., among others, which may commit an approximate volume of at least 230,000 additional bbl/d of firm transportation.

We estimate that the Project will require an investment of approximately U.S.$3,000 million, which will be funded by shareholder contributions and third-party financing expected to be received by VMOS in 2025.

Vista Argentina acquired a minority interest in VMOS and a firm transportation, storage and dispatch capacity of 50,000 bbl/d in the Project, with the possibility of being increased in the event of a Project Expansion.

VMOS intends to develop the Project under the “Incentive Framework for Large Investments” (Régimen de Incentivos para Grandes Inversiones, “RIGI”), pursuant to Law 27,742, Regulatory Decree No. 794/2024 and other Argentine regulations that may amend and/or supplement them, in order to be considered as a long-term strategic export project (proyecto estratégico de exportaciones a largo plazo), and for which VMOS has applied for membership in the RIGI on November 15, 2024.

In addition, on December 13, 2024, Vista Argentina entered into a firm crude oil transportation agreement with VMOS, pursuant to Argentine Decree No. 115/2019, to guarantee the terms and conditions under which it will use crude oil transportation, storage and dispatch services.
