Antofagasta PLC said first-half 2026 revenue rose 18% to $4.48 billion and EBITDA increased 27% to $2.84 billion, as higher copper prices offset rising operating costs and a 9% decline in copper production. Pretax profit jumped 72% to $2 billion and operating cash flow climbed 53% to $2.77 billion. The Chilean miner also lowered its 2026 copper production forecast to 625,000-655,000 tonnes from 650,000-700,000 tonnes after extreme weather disrupted its Los Pelambres mine in Chile, underscoring how weather-related interruptions may curb output even as prices support earnings.
