Company Development

After the Initial Business Combination, and upon taking control of operations, we started a shale development in Bajada del Palo Oeste. In
December 2018, we obtained an unconventional hydrocarbon exploitation concession in such concession for 35 years, until December 2053. In March 2019, we completed and connected our first four-well pad. During 2019, we completed and connected a total
of eight wells, which took our shale production at Bajada del Palo Oeste from zero to over 10,000 boe/d in August 2019, for an average daily production of 4,959 Mboe/d for the year ended December 31, 2019.

On November 30, 2018, the cross assignment of rights between Vista Argentina, through
its wholly owned subsidiary APCO Oil & Gas International Inc. and O&G Developments Ltd. S.A., a wholly owned subsidiary of Royal Dutch Shell plc (“”), was completed. Such assignment was entered into on
August 22, 2018 and announced on October 25, 2018. Pursuant to such agreement, Vista Argentina exchanged a 35% non-operated working interest in the Coirón Amargo Sur Oeste block, for
Shell’s 90% operated working interest in the Águila Mora block plus a contribution of US$10 million, paid by Shell in favor of Vista Argentina. Therefore, Vista Argentina obtained a 90% interest in the Águila Mora block,
while Gas y Petróleo del Neuquén, S.A. the remaining 10%. Following the satisfactory results of the pilot project involving two wells drilled in Águila Mora in 2023, we have incorporated 100 wells into our inventory in such
block.

On September 16, 2021, Vista acquired a 50% non-operated working interest in Aguada
Federal and Bandurria Norte from ConocoPhillips Petroleum Holdings B.V. On January 17,
