Rio Tinto plc annual general meeting

4 April 2024

The annual general meeting of Rio Tinto plc was held on 4 April 2024.

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 22 (inclusive) of the Rio Tinto plc annual general meeting fall into this category, and 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 2 May 2024.

The remaining resolutions 23 to 26 (inclusive) were put to Rio Tinto plc shareholders on a poll at the annual general meeting today. The results of that poll are set out below.

The addresses given by the Chair, Chief Executive and People & Remuneration Committee Chair are available at www.riotinto.com/agm.

* 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 2024, 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  1,255,903,781 (excluding Treasury shares  1,252,502,879).

The Company notes that Resolution 25 '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 25. 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.
