Rio Tinto's Issued Share Capital and Treasury Share Position at 31 October 2026

According to the announcement, Rio Tinto plc's total issued share capital as at 31 October 2026 comprised 1,256,063,762 ordinary shares, each carrying a nominal value of 10p and one vote. Of these, 772,389 ordinary shares are held in treasury and are therefore excluded from voting rights calculations. Treasury shares also do not qualify for dividend payments. The resulting total number of voting rights — 1,255,291,373 — is the figure shareholders and others with disclosure obligations must use as the denominator when determining whether their interest in Rio Tinto plc crosses a reportable threshold under FCA rules.

Rio Tinto's Dual Listed Company Structure and Special Voting Arrangements

The announcement notes that Rio Tinto plc has issued one Special Voting Share of 10p and one DLC Dividend Share of 10p, both linked to its dual listed company merger with Rio Tinto Limited. This structure was designed to place shareholders of both entities in substantially the same position as if they held shares in a single enterprise owning the combined assets of both companies. The Special Voting Share specifically facilitates joint voting by shareholders of Rio Tinto plc and Rio Tinto Limited on joint electorate resolutions, reflecting the integrated governance framework of the dual-listed structure.

Rio Tinto Limited's 371.8 Million Publicly Held Shares Remain Outside Rio Tinto PLC Capital

The disclosure also confirms that there are 371,821,214 publicly held Rio Tinto Limited shares in issue as at the announcement date. These shares do not form part of the share capital of Rio Tinto plc and are therefore not included in the voting rights figure of 1,255,291,373. This distinction is important for investors and institutions assessing their notification obligations, as only Rio Tinto plc ordinary shares are relevant to FCA transparency threshold calculations. Rio Tinto Limited is separately listed in Australia, and its shares sit outside the scope of this particular regulatory disclosure.
