Southern Copper Corporation is embarking on an ambitious $20.5 billion investment plan over the next decade, even as it anticipates a 3% decline in copper production through 2027. The company reported a strong third-quarter 2025 earnings of $1.35 per share, beating analyst expectations, and achieved a year-over-year sales increase of 15% to $3.38 billion. However, the firm has faced production challenges, including a drop in copper output in 2025, and forecasts a further reduction to around 911,400 tons in 2026, though it aims to ramp up production to about 1.6 million tons by 2033.
