Sales grew 9.6% and EBITDA 35.4%, with a 13.2% margin, 250 basis points above Q3'25. These results reflect disciplined execution amid pressure from resin costs and weak demand in some of our markets. Our diversification across geographies, businesses and solutions continues to contribute. In Mexico, sales grew 4.8% and the EBITDA margin expanded 250 basis points to 17.8%. In Argentina, operational stabilization continued despite very low demand. The United States grew double digits and posted its sixth consecutive quarter of positive EBITDA, and Peru, Central America and Brazil delivered double-digit growth. Together, the United States and Other Countries now represent 27% of total sales, compared to 24% in Q3'25. New strategic solutions reached close to 8% of Group sales, and services grew 10.3%, driven by bebbia, which added more than 14,000 net new active subscribers, its highest quarterly figure to date.

Guided by this purpose, we will continue to innovate, strengthen our leadership, and create sustainable long-term value for all our stakeholders.” Figures are expressed in millions of Mexican pesos Indicator Q3'26 Q3'25 %YoY 9M26 9M25 %YoY Net Sales 2,927 2,671 9.6% 8,631 8,251 4.6% Adjusted EBITDA1 385 285 35.4% 1,126 954 18.1% % margin 13.2% 10.7% 250 bps 13.1% 11.6% 150 bps Net Result (2) (198) NM (91) (133) NM ROIC2 5.5% 5.8% (30) bps Net Financial Debt3 3,289 3,789 (13.2%) Net Debt / EBITDA2 2.2x 3.2x (1.0x) ● Net sales reached $2,927 million, a 9.6% increase compared to Q3’25, driven by a 9.5% growth in products and 10.3% in services. All regions grew during the quarter, led by Other Countries and the United States. ● Gross profit closed at $1,206 million with a margin of 41.2%, a 60-basis-point contraction compared to Q3’25, mainly due to higher resin costs. ● Operating income reached $192 million, a 50.7% increase compared to Q3’25. Operating expenses grew 2.6%, below the 9.6% growth in sales, representing 34.7% of sales compared to 37.0% in Q3’25. ● EBITDA closed at $385 million with a 13.2% margin, a 250-basis-point expansion compared to Q3’25, as lower relative expenses more than offset the decline in gross margin. 1 In 2026, Adjusted EBITDA for the quarter includes $5 million in donations, and $25 million on a cumulative basis.

3 ● Net result was a loss of $2 million, compared to a loss of $198 million in Q3’25. In addition to higher operating income, net financing cost decreased to $164 million from $354 million, mainly due to lower foreign exchange effects in Argentina. ● Net Financial Debt / EBITDA leverage closed at 2.2x, improving from 3.2x in Q3’25, driven by higher EBITDA, higher cash balances and lower debt. ● Net sales reached $8,631 million, a 4.6% increase compared to 2025, driven by a 4.1% growth in products and 9.3% growth in services, the latter primarily supported by bebbia. Growth in Other Countries, Mexico and the United States more than offset the decline in Argentina. ● Gross profit was $3,621 million, a 5.0% increase year-over-year, while gross margin expanded 20 basis points to 42.0%, supported by an agile pricing strategy to protect margins amid volatile raw material costs. ● Operating income reached $569 million, a 20.3% increase year-over-year, with operating expenses growing 2.5%, below revenue growth, reflecting operating leverage. ● EBITDA closed at $1,126 million, with EBITDA margin expanding 150 basis points to 13.1%. The improvement came mainly from Mexico and from Argentina narrowing its losses year-over-year, as well as from the United States. ● Net result recorded a $91 million loss, compared to a $133 million loss in 2025. Higher operating income and lower net financing costs were partially offset by a higher tax provision. ● CapEx for the period amounted to $317 million, a 10.3% decrease year-over-year. Investments remained focused on Mexico, mainly in the services segment. Cumulative Results 2026 vs 2025
