3 FOR MORE INFORMATION: investors@gcc.com Q2 2026 EARNINGS Enrique Escalante, GCC’s Chief Executive Officer, commented: “GCC delivered a strong second quarter, achieving revenue and EBITDA growth, supported by favorable demand across our markets and the disciplined execution of our strategy.” Enrique continued, “During the quarter, we reached a key milestone with the start-up of the new kiln at our Odessa plant, while continuing to expand our presence through new aggregates and concrete operations in Texas. Our focus remains on operational excellence as we integrate the new capacity and recent acquisitions to strengthen our position in strategic markets.” FINANCIAL RESULTS Consolidated net sales for the second quarter of 2026 increased by 15% year-on-year to US$418.4 million, up from US$363.9 million in the second quarter of 2025. This was primarily due to increased concrete and cement volumes in the United States and increased cement volumes in Mexico, as well as higher concrete prices in both countries. These gains were partially offset by lower cement prices in the United States. For comparative purposes, consolidated net sales, excluding the exchange rate effect, increased by 11.9% during the quarter. Six months: Consolidated net sales increased by 16.9% to US$713.8 million. This result was driven by higher concrete and cement volumes in the United States and Mexico, increased concrete prices in both countries, and the appreciation of the Mexican peso against the U.S. dollar, partially offset by lower cement prices in the United States. For comparative purposes, consolidated net sales, excluding the appreciation of the Mexican peso against the U.S. dollar, increased by 12.7%.

The most dynamic market segment during the quarter was infrastructure. Six months: U.S. sales increased by 14.8% to US$504.9 million.

The appreciation of the Mexican peso against the U.S. dollar during the quarter increased sales by US$11.1 million. For comparison, sales in Mexico, excluding this effect, increased by 5.6%.

Net financial income totaled US$0.3 million in the second quarter of 2026, compared to US$8.5 million in the prior-year period, a 96.6% decrease.
