South32 Shares Slide After Warning of Mozal Smelter Costs

Highlights:

• South32 Limited (ASX: S32) shares fell 5.3% to AUD 2.96 at the time of writing after warning of an unquantified cost at its Mozal aluminium smelter in Mozambique.
• The company placed its FY26 production guidance for Mozal under review, raising concerns about potential output cuts.
• Investors reacted to the lack of detail, with the smelter’s cost and operational issues prompting uncertainty over South32’s near-term earnings.

Shares of South32 Limited (ASX: S32) dropped sharply on Monday, declining 5.3% to AUD 2.96 at the time of writing, following the company's announcement regarding its Mozal aluminium smelter operations in Mozambique. The mining and metals group flagged an unexpected expense related to the smelter and revealed that it is currently reviewing its FY26 production guidance for the site.

Unspecified Financial Impact Raises Concerns

The company did not disclose the exact financial impact but confirmed that the costs stem from operational issues at Mozal. Investors reacted negatively to the lack of clarity, driving the stock down to its lowest point in weeks. The Mozambique smelter, a key part of South32’s aluminium portfolio, has faced several logistical and cost pressures in recent quarters. The announcement has added to growing concerns over the company’s African operations, particularly in an inflationary environment where energy and transport costs remain volatile. Analysts suggest the uncertainty surrounding both the expense and the potential for reduced output in FY26 may pressure earnings expectations in the near term.

Strategic Review and Market Reaction

South32 Limited said it is working closely with local partners and stakeholders to reassess future production targets and mitigate operational risks. The outcome of this review will determine whether long-term adjustments are needed across its aluminium business. While broader mining and resources stocks showed mixed performance, South32 was among the top decliners on the ASX today. Market watchers will be keeping a close eye on any further updates regarding the Mozal facility, especially as the company prepares to report its FY25 earnings in the coming months. Investors are urged to watch for more detailed disclosures in the upcoming operational update, which may provide insight into how this development will affect the company’s financials and strategic priorities.
