So, what impressed investors?

South32 unveils strong operating update

South32 released its June quarter production report alongside details of a transformational portfolio reshaping.

The headline announcement of South32 shares was the sale of its aluminium value chain business – excluding Mozal Aluminium – to Alcoa in a deal worth up to US$5.6 billion. The transaction also transfers around US$1.2 billion of rehabilitation provisions and is expected to reshape South32 into a more focused base metals producer.

Operationally, the company also delivered several positive surprises. Copper production at Sierra Gorda exceeded FY26 guidance by 2% and generated record annual distributions of US$401 million. Manganese production also beat expectations, finishing 1% above guidance in Australia and 4% ahead in South Africa.

Group sales volumes rose 15% during the June quarter, unlocking around US$200 million of working capital and supporting stronger cash generation.

South32 also returned US$327 million to shareholders during FY26 through dividends and on-market share buybacks while continuing to invest in future growth, spending approximately US$710 million developing its Hermosa zinc-lead-silver project in Arizona.

What management said

The update also marked the company’s first production report under new CEO Matt Daley, who officially succeeded Graham Kerr on 1 July. Daley said:

We continued to deliver strong operating results, exceeding Group production guidance for FY26. We increased quarterly sales volumes by 15%, capturing the benefit of strong market conditions across many of our commodities, and releasing working capital which added to the Group’s cash generation. On 1 July, we announced a step change for South32, with the sale of our aluminium value chain business to Alcoa. Once complete, this sale will unlock significant value for shareholders and reposition South32 as a leading upstream base metals focused company. Our portfolio will be built around high-margin, long-life assets in favourable jurisdictions, with approximately 85% of pro-forma earnings from base and precious metals and approximately 55% production growth from approved projects.

What else should investors know?

Management highlighted continued strong production from Cannington, Sierra Gorda, and its manganese operations. Development at Hermosa remains on schedule, with key US permitting milestones achieved.

Despite higher freight and raw material costs linked to geopolitical disruptions, South32 said it maintained disciplined cost control across the business.

Looking ahead, the company plans to optimise its existing operations while progressing open-pit development at Cannington and managing water impacts at its Australian manganese business. Updated FY27 production guidance for Australia Manganese is expected with its upcoming full-year results on 27 August.

Daley added:

Looking ahead, our focus on operational excellence, a strong balance sheet and transformational growth in base metals leaves us well positioned to deliver value for shareholders.
