Additionally, we are developing our own portfolio of nature-based solutions (“ NBS”) projects to capture carbon in soil and forests. In 2022, we established Aike, a Vista subsidiary dedicated to designing, managing, and executing carbon offset projects, staffed with leading local experts. Aike aims to generate carbon credits of the highest quality, meaning that their impact is measurable, additional, permanent and positive for local communities and biodiversity. We believe NBS represents the most actionable, proven, efficient, and scalable carbon removal alternative currently available. Aike is developing 13 NBS projects in Argentina, across seven Provinces (Salta, Formosa, Corrientes, Santa Fe, Cordoba, San Luis and Buenos Aires), including mixed afforestation and reforestation with native and exotic species, forest conservation, improved forest management, and regenerative agriculture and livestock projects.

By developing a top-tierNBS portfolio, we expect to generate a volume of carbon credits by 2026 that, from that year on, will be equivalent or potentially higher than the annual carbon emissions from our operation.

Emissions and carbon credits calculation methodology

Vista’s GHG emissions inventory reports two of the most prevalent GHG emissions components in oil and gas operations: CH4and CO2. In addition, the calculated emission totals include N2O as well. Although emissions of the other GHG emissions components may exist in the Company’s operation, their relative contribution to the total GHG emissions is considered immaterial.

Emissions from CO2, N2O, and CH4are calculated and converted into total CO2e emissions by multiplying the emissions of each constituent by its respective global warming potential.

The GHG emissions inventory for Vista was developed following best practices and industry guidelines for quantifying, reporting, and managing GHG emissions. Specifically, the Company adheres to: (i) the IPIECA Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions (2011) and (ii) the American Petroleum Institute (“ API”) Compendium of Greenhouse Gas Methodologies for the Oil and Natural Gas Industry (2009). The inventory calculations apply standardized methodologies provided in the API Compendium for Vista’s relevant emission sources, with emission factors derived from published references within the API Compendium. Where actual operational emission factors or parameters are available, these values are incorporated into the GHG emissions inventory to enhance accuracy and representativeness.

Vista’s GHG emissions inventory is structured according to the Operational Controlapproach,
