Rio Tinto reported 2025 full-year results, with consolidated sales revenue of $57.6 billion, up from $53.7 billion in 2024. Underlying EBITDA rose 9% to $25.4 billion, driven by higher copper, bauxite, alumina and lithium volumes and a 5% reduction in operating unit costs.
Underlying earnings were stable at $10.9 billion, while net earnings fell to $10.0 billion from $11.6 billion as depreciation, finance costs and taxes increased. Net cash from operations grew to $16.8 billion, but net debt jumped to $14.4 billion after the $7.6 billion Arcadium Lithium acquisition and $11.4 billion of capital investment.
The company maintained a full-year ordinary dividend of 402 US cents per share, equal to a 60% payout of underlying earnings.

Consolidated sales revenue grew 7% to $57.6 billion, while underlying earnings were stable at $10.9 billion. Net earnings declined to $10.0 billion, mainly due to higher taxes and finance costs linked to a higher net debt position of $14.4 billion after the Arcadium lithium acquisition.
