• 9% YoY CuEq1 growth from three value-generating, world-leading businesses
• Copper production rose 9% YoY, supported by Oyu Tolgoi ramp-up
• Pilbara iron ore production up 13% YoY, with sales up 2% YoY despite cyclone impacts

Rio Tinto released its first quarter 2026 production results, reporting a 9% year-over-year increase in copper equivalent (CuEq) production. This was driven by operational excellence across the company's three value-generating, world-leading businesses. Copper production rose 9% year-over-year, supported by the continued successful ramp-up of the Oyu Tolgoi mine. In iron ore, the company's Pilbara operations delivered the second highest Q1 production since 2018, up 13% year-over-year, with sales up 2% despite impacts from tropical cyclones. Rio Tinto's integrated aluminium business again demonstrated strength and agility, offsetting weather-related disruptions in bauxite. The company also achieved the historic land exchange at Resolution Copper, with the project team focused on unlocking the next phase of one of the world's largest untapped copper deposits. While the outbreak of conflict in the Middle East has led to some economic uncertainty, Rio Tinto's global reach and sophisticated supply chains have enabled the business to operate normally, with limited direct impacts on its operations.

Rio Tinto's 2026 production and sales guidance remains unchanged across its key commodities, including iron ore, bauxite, alumina, aluminium, and copper. The company's unit cost guidance for 2026 is also unchanged.
