Rio Tinto - FY2025 Earnings Analysis

Performance Highlights

Rio Tinto reported full-year 2025 consolidated sales revenue of $57.6 billion, up 7% year-on-year, with underlying EBITDA rising 9% to $25.4 billion, beating the prior-year base despite a 6% decline in iron ore index prices. Underlying EPS was essentially flat at 669 US cents, while net earnings of $10.0 billion fell 14% versus 2024, weighed by higher taxes, increased depreciation from the Oyu Tolgoi ramp-up and Arcadium integration, and $0.9 billion of items excluded from underlying earnings.

The single most important operating driver was the 8% uplift in copper-equivalent production, led by a 61% year-on-year surge in copper output from Oyu Tolgoi as its underground development reached completion, which powered the Copper segment's underlying EBITDA to $7.4 billion — up 114% — and offset an 11% decline in Iron Ore EBITDA to $15.2 billion caused by lower realised prices. The Aluminium & Lithium segment also contributed meaningfully, with underlying EBITDA rising 29% to $4.6 billion on record bauxite production of 62.4 Mt and a 17% improvement in realised aluminium prices, even as roughly $1 billion in US tariff costs were absorbed.

Management Outlook and Forward Catalysts

Management has reaffirmed a 3% copper-equivalent production CAGR target to 2030, anchored by Oyu Tolgoi ramping toward 500 ktpa from 2028 to 2036, a Simandou iron ore ramp to full capacity over 30 months, and lithium projects targeting 200 ktpa LCE capacity by 2028. Capital investment guidance of up to $11 billion for 2026 signals ongoing portfolio construction, while a targeted $5–10 billion in asset disposals — with borates and titanium dioxide under market testing — signals a sharpening of the portfolio toward copper and lithium.

The central investor debate heading into 2026 is whether Copper segment momentum and cost discipline can sustainably offset structural iron ore price pressure, with Pilbara unit cost guidance of $23.5–$25.0 per tonne implying currency headwinds, and net debt having risen sharply to $14.4 billion from $5.5 billion following the $7.6 billion Arcadium acquisition. Bulls will watch Oyu Tolgoi's production ramp, Simandou commissioning milestones, and lithium project delivery; bears will focus on iron ore price trajectory, the $440 million Mongolian tax assessment, and free cash flow declining 28% to $4.0 billion in 2025.
