Antofagasta plc stock (GB0000456144) closed at 4,081.00 pence on September 8, 2026, up 4.70 percent in the latest completed session. Copper's record run helped the move, and the stock ended far above the prior close of 3,898.00 pence.

H1 figures lifted by copper

In its half-year report for the six months ended June 30, 2026, Antofagasta reported revenue of US$ 972 million, up from US$ 325 million a year earlier, and adjusted EBITDA of US$ 641 million, up from US$ 152 million. The margin reached 66 percent, compared with 47 percent in H1 2025, according to the report text published on September 9, 2026 by Vocus.

The same report also shows why the market kept a close eye on the group: revenue rose by US$ 647 million year on year, while adjusted EBITDA increased by US$ 489 million. For investors, that is the key comparison, because the stronger margin suggests operating leverage from higher copper pricing and sales recovery.

Analysts still see room

According to MarketScreener, Antofagasta's sector page shows a 1-year revenue figure of 8.62 billion, net margin of 15.42 percent and EBIT margin of 39.14 percent. The same page also lists a close of 10.10 EUR and a 1.00 percent move in the comparison view, giving a separate cross-check on the shares' relative strength.

Reuters market wrap data cited in that report said Antofagasta was among the FTSE 100 leaders on September 8, 2026, with the session high and close both around 4,081.00 pence. The article also said the group now expects adjusted profit before tax for 2026 of at least GBP 380 million, above consensus of GBP 340.9 million.

Antofagasta stock closed at 4,081.00 pence on September 8, 2026, with the move backed by a 4.70 percent daily gain. The reference price was set in London trading, and the group's latest half-year numbers and full-year guidance give the move a clear fundamental backdrop.
