Antofagasta faces Chile strike vote and Citi rates Antofagasta stock Buy
Published on 10/01/2026 at 09:52 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Antofagasta stock was trading at EUR 43.75 at Lang & Schwarz on October 1, 2026 at 9:38 a.m. CEST, down 0.82 percent versus the EUR 44.11 prior close. On September 23, 2026, MarketScreener reported that unions at the Centinela copper mine were seeking a strike vote after failed negotiations. ScrapMonster reported on September 7, 2026 that Citi maintained a Buy rating and a GBp 4,400 price target after the August 13 results.
Centinela adds an operating risk
The labor dispute adds a fresh operational variable to a company already carrying lower copper-volume guidance. MarketScreener identifies Centinela as the mine affected by the proposed strike vote, while its profile lists Antofagasta as a specialized mining and metals group with 8,457 employees.
Antofagasta's revised full-year 2026 copper guidance stands at 625,000 to 655,000 tonnes, compared with the previous 650,000 to 700,000 tonnes. The same August results showed H1 2026 copper production of 285,000 tonnes, down 9 percent from H1 2025, according to ScrapMonster.
Profit growth meets lower output
The first-half figures were stronger on pricing and margins. Revenue increased 18 percent to USD 4.50 billion in H1 2026, EBITDA rose 27 percent to USD 2.84 billion, and the EBITDA margin reached 63.40 percent, as reported by OpenBook Analytics on September 10, 2026.
The contrast is important for the stock: stronger earnings did not remove the volume risk created by weather disruption and labor uncertainty. Citi's GBp 4,400 target stands 18.67 percent above the LSE last price of GBp 3,707 at 8:49 a.m. BST on October 1, 2026, while the revised production range sets a lower operational baseline.
October results provide the next test
Antofagasta's next scheduled reporting date is October 15, 2026, according to MarketScreener. That report should show whether Centinela labor negotiations alter output expectations or leave the full-year guidance unchanged.
