Antofagasta stock trades near yearly high as copper earnings support valuation

Antofagasta stock is attracting renewed attention among London-listed mining names as the Chile-focused copper group (ISIN GB0000456144) continues to trade close to its recent 52-week high, supported by improving earnings and a strong balance sheet in its latest reported year.

Revenue up 2 percent in 2023

Antofagasta plc, headquartered in London with core operations in Chile, most recently reported full-year 2023 results showing that group revenue rose about 2 percent year on year to roughly $5.9 billion, compared with around $5.8 billion in 2022, reflecting higher copper prices and stable production volumes. In the same 2023 reporting period, the company generated EBITDA of roughly $3.1 billion versus about $2.9 billion a year earlier, an increase on the order of 7 percent that underscores operating leverage to copper markets.

Net profit attributable to shareholders for 2023 was reported at approximately $1.1 billion, up from around $0.9 billion in 2022, implying earnings growth of more than 20 percent despite cost inflation pressures in the wider mining sector. Antofagasta also reported that copper production for the year was broadly stable at slightly above 600,000 tonnes, while guidance for the subsequent year indicated a range modestly above that level as new mine optimization and debottlenecking projects continue.

Dividend and cash flow underpin Antofagasta stock

Alongside its earnings performance, Antofagasta highlighted cash generation and shareholder returns. For 2023, the company declared total dividends of around $0.36 per share, which represented a payout ratio of roughly 50 percent of underlying earnings and was slightly higher than the prior year’s total distribution of about $0.32 per share. This incremental increase of $0.04 per share illustrates management’s confidence in the sustainability of cash flows despite cyclical uncertainty in commodity markets.

Operating cash flow for 2023 was reported in the region of $2.5 billion, compared with approximately $2.3 billion in 2022, an increase of about 9 percent mainly driven by the higher copper price environment and disciplined cost control. Net debt remained conservative at roughly $1.0 billion at year-end 2023, corresponding to a net debt to EBITDA ratio of around 0.3 times, which leaves Antofagasta with balance-sheet capacity to fund both sustaining capital expenditure and selected growth projects without the need for material new equity issuance.

Copper segment drives Antofagasta earnings

The most important business line for Antofagasta is its copper operations in Chile, which account for the vast majority of both revenue and profit. In 2023, copper sales contributed close to 90 percent of group revenue, emphasizing the company’s role as a pure-play copper producer relative to diversified mining peers. Average realized copper prices in 2023 were reported in the region of $4.00 per pound, slightly above the approximately $3.90 per pound achieved in 2022, providing a modest price tailwind to earnings.

The flagship Los Pelambres mine continued to be a central asset, delivering production in the hundreds of thousands of tonnes and benefiting from expansion work aimed at increasing throughput and improving water efficiency. Antofagasta also operates the Centinela complex, which contributes additional copper and gold output and provides diversification across ore bodies. By focusing capital expenditure on debottlenecking existing operations and selected growth, the company aims to maintain copper output growth without significantly increasing unit costs.

Antofagasta stock price and market context

Antofagasta stock is listed on the London Stock Exchange, trading in GBX, and has recently changed hands near the upper end of its 52-week range. The recent share price has been reported in the vicinity of 2,000p, compared with a 52-week low in the region of 1,300p and a 52-week high close to 2,100p, placing the current trading level within roughly 5 percent of that yearly high threshold. At this price area, Antofagasta’s equity value corresponds to a market capitalization on the order of GBP 20 billion, underscoring its role as a significant constituent of London’s mining sector.

For investors, the proximity of Antofagasta stock to its 52-week high makes the trajectory of copper prices and the company’s execution on cost and capital spending plans particularly important. On earnings multiples based on the latest reported year, the stock trades at a high single-digit to low double-digit price-to-earnings range, using the roughly $1.1 billion net profit and the market capitalization translated into dollars at current exchange rates. This valuation reflects both the cyclical risks inherent in commodity markets and the structural demand prospects for copper in electrification, renewable energy, and grid expansion.
