| | | During the period, Management responsibility of the closed Gove Refinery moved from the Group's central closure team (as part of "Other operations") to the Aluminium and Lithium product group. In the second half of 2025, the Group's reportable segments were updated to reflect the organisational restructure announced on 27 August 2025. Accordingly comparative information has been restated. | | Segmental revenue includes consolidated sales revenue plus the equivalent sales revenue of equity accounted units (EAUs) in proportion to our equity interest (after adjusting for sales to/from subsidiaries). Segmental revenue measures revenue on a basis that is comparable to our underlying EBITDA metric. | | Underlying EBITDA (calculated on page 38) is reported to provide greater understanding of the underlying business performance of Rio Tinto's operations. | | Consolidated sales revenue includes subsidiary sales of US$178 million (30 June 2025: US$128 million) to equity accounted units which are not included in segmental revenue.
