South32 Limited

South32 reported underlying EBITDA of USD 1.1 billion, group operating margin of 28.2%, and growth in underlying earnings of USD 435 million for the half. Net debt was USD 25 million at period-end. Management said FY '26 production unit guidance is unchanged across operated assets. It also announced a fully franked ordinary dividend of USD 175 million for H1 FY '26 and a USD 100 million increase in the USD 2.6 billion capital management program, leaving USD 209 million remaining to be returned to shareholders. For Taylor, management said assessment of project milestones and capex will be completed in H2 FY '26; for Sierra Gorda, the fourth grinding line feasibility study is nearing completion with a potential joint FID in mid-calendar year 2026. For Mozal, Alcoa’s FY '26 production guidance was revised to 135,000 tonnes, with FY '27 guidance at 140,000 tonnes versus 179,000 tonnes of capacity. For Cannington, the underground ore reserve increased 28% from 3 million tonnes to 13 million tonnes, adding about 2 years of underground life. Management also said about USD 65 million to USD 80 million of spend is expected over '27 and '28 to support further underground extension.

Graham Kerr emphasized that the half was driven by strong operating performance and higher base and precious metals prices, with the company capturing favorable market conditions while keeping production guidance unchanged. He repeatedly framed the portfolio as being in a strong position for cash generation, shareholder returns, and growth investment, pointing to Taylor, Hermosa, Sierra Gorda, Cannington, and Ambler as value-creating options. His tone was confident but measured, especially on execution risk, saying reviews and rebaselining are normal parts of large project delivery.

Sandy Sibenaler did not provide a detailed standalone script in the excerpt, but the financials presented showed strong profitability and balance sheet resilience: USD 1.1 billion underlying EBITDA, 28.2% group operating margin, USD 435 million growth in underlying earnings, and net debt of just USD 25 million. Management also highlighted a capital returns framework with a USD 175 million dividend and a USD 100 million increase to the capital management program, plus USD 209 million still to be returned. The messaging around cash was that commodity price tailwinds and planned inventory drawdown at Mozal should support second-half cash generation.

Analysts focused on Sierra Gorda execution, asking about management changes and delays to the fourth grinding line; Kerr said the project had issues around engineering and licensing but that new leadership had improved momentum and that the project was now in better shape. Questions on Hermosa centered on budget and schedule, and management said spend to date was just over USD 1 billion, or about 48% of the budgeted schedule, with no major movement in expected dates or capital costs so far. Analysts also pressed on Mozal and Hillside: Kerr said Mozal is heading to care and maintenance because power cannot be secured economically, with ongoing maintenance costs of about USD 5 million a year and closure/rehab estimated at about USD 119 million, while Hillside has more time because its current power contract runs to 2031.
