Southern Copper — Apr 28, 2026 release

In addition, the Company’s cash cost decreased from a cost of $0.77 to -$0.11 per copper pound (-114%), driven by a growth in by-product revenues for all our by-products and cost efficiencies across operations. ​ As the world continues to navigate the economic and inflationary impacts arising from current global conflicts, the Company has remained resilient and committed to its operational objectives of increasing production to 1.6 million tons while maintaining the cost-efficiency discipline that defines it. This year, we will remain focused on achieving our operational targets and advancing the development of our projects.” ​ Key Financial Data ​ ​ ​ 1Q26 ​ 1Q25 ​ Variance ​ 4Q25 ​ Variance ​ ​ ​ ​ ​ ​ $ ​ % ​ ​   ​ ​ ​ $ ​ % ​ ​ (in million except per share amount and %s) Sales   ​ ​ ​ $ 4,251.4   ​ ​ ​ $ 3,121.9   ​ ​ ​ $ 1,129.5   ​ ​ ​ ​   ​ 36.2%   ​ ​ ​ $ 3,869.8 ​ $ 381.7   ​ ​ ​   ​ 9.9% Cost of sales ​ ​ 1,498.8 ​ ​ 1,319.2 ​ ​ 179.6 ​ ​ 13.6% ​ ​ 1,471.5 ​ ​ 27.2 ​ ​ 1.9% Operating income ​ ​ 2,480.4 ​ ​ 1,535.5 ​ ​ 944.9 ​ ​ 61.5% ​ ​ 2,110.4 ​ ​ 370.0 ​ ​ 17.5% Net income ​ $ 1,576.9 ​ $ 945.9 ​ $ 631.0 ​ ​ 66.7% ​ $ 1,307.9 ​ $ 269.0 ​ ​ 20.6% Net income margin ​ ​ 37.1% ​ ​ 30.3% ​ ​ 6.8pps ​ ​ 22.4% ​ ​ 33.8% ​ ​ 3.3pps ​ ​ 9.8% Adjusted EBITDA ​ ​ 2,712.8 ​ ​ 1,745.5 ​ ​ 967.3 ​ ​ 55.4% ​ ​ 2,310.5 ​ ​ 402.3 ​ ​ 17.4% Adjusted EBITDA margin ​ ​ 63.8% ​ ​ 55.9% ​ ​ 7.9pps ​ ​ 14.1% ​ ​ 59.7% ​ ​ 4.1pps ​ ​ 6.9% Income per share ​ $ 1.92 ​ $ 1.15 ​ $ 0.77 ​ ​ 67.0% ​ $ 1.56 ​ $ 0.36 ​ ​ 23.1% Capital investments ​ ​ 441.9 ​ ​ 317.8 ​ ​ 124.1 ​ ​ 39.0% ​ ​ 422.6 ​ ​ 19.2 ​ ​ 4.6% ​ ​ ​ ​ ​ 1Q26       www.s
