31, 2024, were calculated using a price of 69.4 $/bbl for oil, 25.7 $/boe for LPG and 2.9 $/MMbtu for natural gas, in accordance with SEC regulations. For CS-01block, in Mexico, the proved reserves as of December 31, 2024, were calculated using a price of 61.5 $/bbl for oil, and 2.8 $/MMbtu for natural gas, in accordance with SEC regulations. The estimated certified future net cash flows attributable to Vista’s interests in the P1 reserves, as of December 31, 2024, are summarized below:

Definitions and Methodology

| • |     | According to SEC regulations, proved reserves are those quantities of oil and gas which, by analysis of                                                                                                                                         
 geoscience and engineering data, can be estimated with “reasonable certainty” to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government          
 regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. |

| • |     | Oil includes crude oil and condensate, C5+ and NGL; NGLs represent less than 1% of total reserves of the Company. |
