Welcome to our dedicated page for Rio Tinto SEC filings (Ticker: RIO), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Rio Tinto plc filings document a foreign private issuer whose U.S. security is tied to a dual-listed mining group operating through Rio Tinto plc and Rio Tinto Limited. Form 6-K reports and Form 20-F annual-report materials disclose production results, financial results, mineral resources and ore reserves, project developments, safety and operational risk, and portfolio activity across iron ore, copper, aluminium, bauxite and lithium.
The filings also record annual general meeting notices and results, board and executive governance, total voting rights and issued capital, dividend and distribution notices, equity-security admissions and cessations, director and PDMR/KMP shareholdings, substantial-holder notices, and other stock-exchange announcements furnished to U.S. regulators.
Rio Tinto reported solid 2025 full year results, with underlying EBITDA rising 9% to $25.4 billion and net cash from operating activities up 8% to $16.8 billion, helped by an 8% increase in copper-equivalent production and tighter cost control.
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.
The company maintained a 60% payout ratio with an ordinary dividend of $6.5 billion, or 402 US cents per share, marking a decade at the top of its stated range. Iron ore EBITDA fell on lower prices, while Copper EBITDA more than doubled and Aluminium & Lithium grew 29%, reflecting portfolio diversification and growth in copper and lithium projects such as Oyu Tolgoi, Simandou, Rincon and Nemaska.
Rio Tinto reports a planned executive change, as Isabelle Deschamps, Chief Legal, Governance & Corporate Affairs Officer, has decided to leave the company during 2026 after five years in the role. She joined in 2021 and will remain in her position until at least mid‑2026.
The company plans a rigorous succession process while she continues to ensure continuity. Statements from Rio Tinto’s Chief Executive and from Ms. Deschamps highlight her role in strengthening governance, supporting business development and key partnerships, and reinforcing the group’s broader strategy and commitment to responsible mining.
Rio Tinto plc and Rio Tinto Limited have announced they are no longer considering a possible merger or other business combination with Glencore plc. The group concluded it could not reach an agreement that would deliver value to its shareholders, applying the disciplined framework outlined at its Capital Markets Day in December 2025.
The company issued this as a formal “no intention to bid” statement under Rule 2.8 of the UK Takeover Code. As a result, Rio Tinto and any concert parties are now restricted by Rule 2.8, although they retain limited rights to reconsider a transaction if specific events occur, such as a third-party offer for Glencore or a material change of circumstances.
Rio Tinto plc filed a 6-K summarising January 2026 announcements and confirming its share capital and voting rights. As of 31 December 2025, Rio Tinto plc had issued 1,256,010,314 ordinary shares of 10p each, including 1,717,902 shares held in treasury.
After excluding treasury shares, the company reports a total of 1,254,292,412 voting rights, which shareholders can use as the reference figure when assessing disclosure thresholds under UK transparency rules. The notice also explains the dual listed company structure with Rio Tinto Limited and notes 371,216,214 publicly held Rio Tinto Limited shares that are separate from Rio Tinto plc’s share capital.
Rio Tinto reported strong fourth quarter and full-year 2025 operating results, highlighted by an 8% year-on-year increase in copper equivalent production and 5% higher shipments. Pilbara iron ore achieved record quarterly production and shipments in Q4, with full-year Pilbara shipments of 326.2 Mt on a 100% basis, only slightly below 2024 despite earlier cyclone disruption. Copper production on a consolidated basis rose 11% to 883 kt for 2025, driven by the ramp-up of Oyu Tolgoi, where underground development is now complete and delivering record quarterly output. Bauxite reached a record 62.4 Mt, up 6%, aluminium rose 3% to 3.38 Mt and lithium carbonate equivalent production was 57 kt, reflecting growth in Argentina operations. The company met or exceeded its 2025 production guidance across product groups and kept 2026 production guidance unchanged from prior disclosures, while exploration and evaluation expense fell to $795 million from $935 million in 2024.
Rio Tinto filed a Form 6-K summarising a series of December 2025 announcements by Rio Tinto plc and Rio Tinto Limited. The report bundles stock exchange notices and media releases on capital structure, management shareholdings, project development and community agreements.

The filing also highlights Indigenous agreement updates and a $191 million feasibility study for the Rhodes Ridge Joint Venture on an iron ore mine of up to 50Mtpa in the Pilbara.
