An update from South32 ( (AU:S32) ) is now available.

South32 has placed its Mozal Aluminium smelter near Maputo, Mozambique, on care and maintenance as of 15 March 2026 after failing to secure sufficient, affordable power beyond March, despite six years of negotiations with the Mozambican government, Eskom and other stakeholders. The move ends 25 years of high-quality primary aluminium production for domestic and export markets at the site and entails one-off costs of about US$60 million plus ongoing annual care and maintenance expenses of around US$5 million, while alumina previously supplied to Mozal from Worsley Alumina will now be redirected to third-party customers at index-linked prices, altering South32’s sales mix and local economic footprint.

The most recent analyst rating on (AU:S32) stock is a Buy with a A$5.00 price target. To see the full list of analyst forecasts on South32 stock, see the AU:S32 Stock Forecast page.
