Investor Presentation March 2026 11 Climate event in Bahía Blanca - Impact on the Cerri Complex On Friday, March 7, 2025, extraordinary rainfall was recorded in Bahía Blanca and its surrounding areas, reaching a total of 312 mm (12.2 in) over a continuous 24-hour period, thus surpassing historical records in the region. These intense rains caused several tributaries that cross the city to overflow. These included the Saladillo de García creek, whose channel directly crosses the tgs Cerri complex, and the Sauce Chico creek, located near the facilities. As a result, widespread flooding occurred throughout the industrial complex, reaching water levels between 1.5 and 2 meters (5 to 6.2 feet). On Saturday, March 8, at noon, access to the complex was restored, and the personnel who had been there since 6:00 a.m. the previous day were able to return to their homes. Simultaneously, the damage was assessed to begin developing an action plan for damage assessment and continuity of operations.
