Southern Copper Corporation achieved record net sales, adjusted EBITDA, and net income in Q3 2025, driven by strong byproduct production and improved metal prices, despite a decline in copper output.

• Net sales reached $3.4 billion, reflecting a 15% increase year-over-year due to higher prices for copper, molybdenum, silver, and zinc.
• Molybdenum production rose 8%, and silver sales surged 65% on volume growth and price increases, underscoring strong demand in the byproduct market.
• Cash costs for copper were competitive at $0.42 per pound, positioning the company favorably within the industry.
• Zinc production jumped 46%, primarily from enhanced output at the Buenavista zinc concentrator, highlighting operational efficiencies.
• Year-to-date copper production decreased by 3% to 714,098 tons, primarily due to lower ore grades impacting operations in Peru and Mexico.
