1 October 2020

In accordance with the Financial Conduct Authority’s (FCA) Disclosure Guidance and Transparency Rule 5.6.1R, Rio Tinto plc notifies the market that as of 30 September 2020:

1.Rio Tinto plc’s issued share capital comprised 1,255,746,726 Ordinary shares of 10p each, each with one vote.

2.9,044,856 Ordinary shares of 10p each are held in treasury. These shares are not taken into consideration in relation to the payment of dividends and voting at shareholder meetings.

Accordingly the total number of voting rights in Rio Tinto plc is 1,246,701,870. This figure may be used by shareholders (and others with notification obligations) as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change to their interest in, Rio Tinto plc under the FCA’s Disclosure Guidance and Transparency Rules.

Note:

As at the date of this announcement:

(a)Rio Tinto plc has also issued one Special Voting Share of 10p and one DLC Dividend Share of 10p in connection with its dual listed companies (‘DLC’) merger with Rio Tinto Limited which was designed to place the shareholders of both companies in substantially the same position as if they held shares in a single enterprise owning all of the assets of both companies;

(b)the Special Voting Share facilitates joint voting by shareholders of Rio Tinto plc and Rio Tinto Limited on joint electorate resolutions; and

(c)there are 371,216,214 publicly held Rio Tinto Limited shares in issue which do not form part of the share capital of Rio Tinto plc.
