South32 has invited registered sell-side analysts who monitor South32’s securities to submit their estimates in respect of year ended 30 June 2025 to an external web-based platform hosted by Vuma Financial Limited (Vuma) (an independent service provider). South32 does not consider the information in the table to be materially price sensitive. It is provided as a courtesy to all interested persons who would not otherwise have access to it.

The consensus figure for a particular item is the arithmetic mean of all estimates submitted for that item by participating sell-side analysts and collated by Vuma. Analyst estimates entered into Vuma that are materially out of date, or that contain a manifest error have been excluded from the aggregate consensus figures. The following estimates were excluded given they included a manifest error:

• Two sets of estimates for Underlying net finance cost: has been reported on a statutory basis which incorrectly excludes net finance costs from our manganese and Sierra Gorda EAIs
• Two set of estimates for total capital expenditure including equity accounted investments: has been reported as n/a
• One set of estimates for Cerro Matoso: has been reported as n/a
• One set of estimates for Sierra Gorda ore processed, payable silver production, silver realised price and payable silver sales: has been reported as n/a
• One set of estimates for Sierra Gorda payable gold sales: this estimate is nil, which materially differs from reported actuals
• One set of estimates for Cannington ore processed: has been reported as n/a
• One set of estimates for Australia Manganese realised price: has been reported as n/a
• One set of estimates for Cannington zinc realised price: this estimate differs materially from reported actuals
• One set of estimates for Brazil Aluminium unit cost: has been reported as n/a

The consensus figures reflect the opinions of the participating sell-side analysts and are not directly or indirectly attributable to South32. South32 has not commented on or verified the information provided by the contributors (other than to correct factual inaccuracies or to direct the analyst(s) to information previously disclosed to the Australian Securities Exchange). Neither Vuma nor third party sell-side analysts have access to South32’s internal financial information. Publication of the consensus figures should not be treated as an express or implied endorsement of the information by South32. South32 expressly disclaims any endorsement of or concurrence with the information and makes no comment about its own forecast performance.

South32’s actual performance for the period is not yet known and may differ from the consensus figures. A significant number of variable factors impact the Group’s financial results, including accounting determinations and external factors (such as fluctuations in exchange rates and commodity prices) immediately prior to the end of the financial year.
