Rio Tinto Plc (RIO) delivered impressive fourth-quarter numbers that sent shares climbing Wednesday, with the mining giant posting a 4% year-over-year increase in Pilbara iron ore production to 89.7 Mt. Even better, shipments from the region jumped 7% to 91.3 Mt as the company bounced back from earlier weather headaches.
The real headline here is Simandou, which moved from development phase to actual operations this quarter and completed its first shipment. That's the kind of milestone investors pay attention to when they're thinking about future growth.
Not everything was spectacular though. Bauxite production held steady at 15.4 Mt year-over-year, while Alumina dipped 1% to 2.0 Mt during the quarter. Nothing alarming, just the usual operational variations.
The bigger picture for 2025 looks solid: copper equivalent production climbed 8% year-over-year with shipments up 5%, thanks to Oyu Tolgoi ramping up, record bauxite output, and lithium operations performing well.
What's Next
Looking ahead to fiscal 2026, Rio Tinto expects Bauxite production between 58-61 Mt and Alumina production of 7.6-8.0 Mt. The company is projecting Pilbara iron ore sales in the range of 323-338 Mt.
Management's Take
CEO Simon Trott sounded pretty pleased with the results, calling out "standout production results" driven by strong execution and project delivery across the portfolio. He highlighted the Pilbara's record quarterly iron ore output after recovering from weather disruptions, celebrated that first Simandou shipment as a growth milestone, and pointed to continued record copper production following the completion of the Oyu Tolgoi underground project.
Trott also noted significant gains in bauxite output, steady lithium production growth matching 2025 targets, and said the company's streamlined operating model is starting to deliver real performance and value improvements.
Rio Tinto is set to release full-year 2025 results on Thursday, February 19, 2026.
Price Action: Rio Tinto shares jumped 3.36% to $88.56 during premarket trading Wednesday, hitting a new 52-week high.
