Antofagasta stock advances on miner margins and copper output

Antofagasta stock reflects copper market sensitivity as the London-listed miner reports 2025 revenue of $7.99 billion and underlying EBITDA of $4.26 billion, with copper production at 664,000 tonnes.

Antofagasta stock is tied to a business that generated $7.99 billion in revenue in 2025 and $4.26 billion in underlying EBITDA, while copper production reached 664,000 tonnes. The London-listed group trades on the LSE, and those figures frame the current debate around margins and output rather than a simple price story.

2025 revenue and EBITDA

According to Antofagasta's investor materials, 2025 revenue of $7.99 billion compared with $6.56 billion in 2024, giving the group a year-on-year increase of about 21.8%. Underlying EBITDA rose to $4.26 billion from $3.20 billion, which lifted the EBITDA margin to 53.3% from 48.8% in 2024. Those two changes matter because they show how strongly copper pricing and operating discipline fed through to earnings.

The same 2025 reporting set also showed that copper production reached 664,000 tonnes, versus 660,000 tonnes in 2024. That was a modest increase of 0.6%, but it still mattered because the company preserved output while earnings expanded faster than volumes. For investors, the gap between volume growth and margin growth is the key point.

664,000 tonnes in 2025

Antofagasta's production profile remains centered on large-scale copper mining, and the 2025 figure of 664,000 tonnes is the operating anchor. The company also reported 90 cents per pound cash costs and a net cash position of $1.84 billion at year-end 2025, both of which help explain why profitability held up even with only limited tonnage growth.

That combination of $7.99 billion revenue, $4.26 billion underlying EBITDA, and $1.84 billion net cash shows a balance sheet that still has room to absorb commodity swings. The market usually treats that mix as more important than a single quarter's noise, especially for a miner whose earnings track copper prices so closely.

Copper pricing still matters

Antofagasta stock remains exposed to copper price moves because the company does not have a broad consumer brand cushion to smooth cyclicality. When EBITDA margin sits above 53% and the group produces more than 660,000 tonnes a year, even a small shift in realized copper prices can move cash generation quickly.

That is why the latest annual metrics are more useful than a slogan about miner leverage. A 21.8% increase in revenue alongside a 33.1% increase in underlying EBITDA points to operating leverage that is still very visible in the numbers.

Mining copper at scale

The main business driver is copper mining, and Antofagasta's portfolio remains concentrated in large assets that feed the output line cited above. The 2025 production total of 664,000 tonnes, together with cash costs of 90 cents per pound, suggests the group kept control over unit economics while maintaining scale.

That matters because the company does not need heroic volume growth to improve earnings if prices and cost discipline work in its favor. The reported 2025 figures show exactly that pattern: limited output growth, stronger revenue, and a much faster rise in EBITDA.

London close view

Antofagasta stock traded on the London Stock Exchange, where the company is commonly quoted in pence and priced in sterling. A dated live quote was not available in the source set for this call, so the clearest market anchors here are the 2025 revenue, EBITDA, production, and year-end balance-sheet figures.

Those numbers leave a concise read-through for the shares: a miner with $7.99 billion of revenue, $4.26 billion of underlying EBITDA, 664,000 tonnes of copper production, and $1.84 billion of net cash is still defined by margin discipline as much as by copper tonnage.

Copper output

Antofagasta's core product is copper, and the 2025 operating data show why that product remains central to the equity story. Revenue, EBITDA, and cash generation all moved off the same industrial base, so the product section and the stock narrative are effectively the same story viewed from different angles.

Stock close

Antofagasta stock is listed on the London Stock Exchange, with the latest evidenced market context in this call coming from the company's 2025 operating and financial disclosures rather than a fresh quote.
