Rio Tinto plc annual general meeting

3 April 2025

The annual general meeting of Rio Tinto plc was held on 3 April 2025.

The Resolutions 20 to 23 (inclusive) were proposed to Rio Tinto plc shareholders on a poll at the annual general meeting today. The results of that poll are set out below.

Under Rio Tinto's dual listed companies structure established in 1995, decisions on significant matters affecting shareholders of Rio Tinto plc and Rio Tinto Limited in similar ways are taken through a joint electoral procedure. Resolutions 1 to 19 (inclusive) and Resolution 24 of the Rio Tinto plc annual general meeting fall into this category. In accordance with Rio Tinto's usual practice for joint decision matters, the results of the voting on these resolutions will be announced shortly after the Rio Tinto Limited annual general meeting which will be held in Australia on 1 May 2025, once voting on these resolutions has been concluded.

The addresses given by the Chair and Chief Executive are available at www.riotinto.com/agm .

Resolutions	For / discretion (number of votes)	% for / discretion	Against (number of votes)	Total votes validly cast	% of issued share capital voted	Withheld*
20. General authority to allot shares	874,962,881	97.22	24,999,932	899,962,813	71.77%	2,046,157
21. Disapplication of pre-emption rights	894,753,496	99.53	4,239,858	898,993,354	71.69%	3,014,919
22. Authority to purchase Rio Tinto plc shares	711,804,446	79.08	188,310,626	900,115,072	71.78%	1,894,892
23. Notice period for general meetings other than annual general meetings	867,091,016	96.33	33,023,751	900,114,767	71.78%	1,895,195

* It should be noted that a vote 'withheld' is not a vote in law and is not counted in the calculation of the proportion of votes for and against each resolution.

For the purposes of section 341 of the UK Companies Act 2006, the votes validly cast are expressed in the table as a percentage of Rio Tinto plc's total issued share capital (excluding shares held in Treasury) as at 8pm on 2 April 2025, being the time at which a shareholder had to be registered in the Company's register of members in order to attend and vote at the annual general meeting. The number of shares in issue was 1,255,960,289 (excluding Treasury shares 1,253,972,387).

The Company notes that Resolution 22 'Authority to purchase Rio Tinto plc shares' was passed with less than 80% of votes in favour. Shining Prospect (a subsidiary of the Aluminium Corporation of China "Chinalco") voted against Resolution 22. Chinalco has not sold any of its shares in Rio Tinto plc and now has a holding of over 14% given its non-participation in the Company's significant share buyback programmes. This places Chinalco close to the 14.99% holding threshold agreed with the Australian Government at the time of its original investment in Rio Tinto.

In accordance with Listing Rule 9.6.2 copies of all the resolutions passed, other than ordinary business, will be submitted to the National Storage Mechanism and will shortly be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism .
