CEO’S REPORT

TO THE BOARD OF DIRECTORS

on the Results of Fiscal Year 2025

During 2025, Grupo Carso operated in an environment characterized by moderate growth in the Mexican economy, more cautious consumer behavior, and volatility in key macroeconomic variables, particularly exchange rates and investment cycles.
