Why Antofagasta shares fell on a record $5.2 billion profit day — dividend, debt and 2026 guidance
London, February 17, 2026, 09:27 GMT — Regular session Antofagasta shares dropped 3.4% as of 0820 GMT on Tuesday, despite the copper miner’s record annual core profit. Investors focused instead on the firm’s rising debt and a sizable investment load. The stock still shows a 10.5% gain for the year, according to Reuters. CEO Iván Arriagada said construction work at Centinela’s second concentrator has reached about 70% completion.
