Results of Rio Tinto annual general meetings

7 May 2020

The annual general meetings of Rio Tinto plc and Rio Tinto Limited were held on 8 April 2020 and

7 May 2020 respectively.

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 20 in table 1 below, contained in the notices of meeting for each of Rio Tinto plc and Rio Tinto Limited, fall into this category.

Resolution 21, in table 2 below, contained in the notices of meeting for both Rio Tinto plc and Rio Tinto Limited, was proposed as a class rights action. This resolution was put to Rio Tinto plc and Rio Tinto Limited shareholders voting as separate electorates.

Resolutions 22 to 25 of the Rio Tinto plc notice of meeting, in table 3 below, were put to Rio Tinto plc shareholders only and resolutions 22 to 24 of the Rio Tinto Limited notice of meeting, in table 4 below, were put to Rio Tinto Limited shareholders only.

All resolutions were carried, with the exception of the requisitioned resolutions 23 and 24 put to shareholders of Rio Tinto Limited only. Requisitioned resolution 23 was not carried and requisitioned resolution 24 was not valid, as it was conditional on resolution 23 being carried by the required majority. All resolutions were decided by poll.

The results of the Rio Tinto plc polls were certified by the scrutineer, Computershare Investor Services PLC, and the results of the Rio Tinto Limited polls were as reported by the duly appointed returning officer, a representative of Computershare Investor Services Pty Limited. These results are as set out below. Information on the final proxy position for each company is detailed in Appendix 1, and the votes cast on each resolution as a percentage of the issued capital of each company is set out on our website at www.riotinto.com/invest/shareholder-information/annual-general-meetings.

Table 3

The following resolutions were put to Rio Tinto plc shareholders only and carried at the Rio Tinto plc meeting held on 8 April 2020. Resolution 22 was carried as an ordinary resolution and resolutions 23 to 25 as special resolutions. In accordance with the UK Listing Authority’s Listing Rule 9.6.2, copies of all the resolutions passed by Rio Tinto plc shareholders, other than ordinary business, have been submitted to the National Storage Mechanism and are available for inspection at http://www.morningstar.co.uk/uk/NSM. The results of the polls were as follows:

Resolution		Total Votes Cast	For		Against		Withheld/ Abstained
			Number	%	Number	%
22.	General authority to allot shares	932,025,745	849,333,521	91.13	82,692,224	8.87	13,619,976

Resolution 24 ‘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 24. Chinalco has not sold any of its shares in Rio Tinto plc and now has a holding of just 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.

Appendix 1

FINAL PROXY POSITION

Shareholders are encouraged to look at the voting figures provided in the main part of this announcement, as proxy figures may not be an accurate indication of the voting at the annual general meetings; a proxy is an authority or direction to the proxy holder to vote and not a vote itself.

References in this appendix in respect of resolutions 1-20 to an appointment specifying that a proxy abstain on a resolution should, when referring to voting at Rio Tinto plc’s annual general meeting, be taken as references to the appointment specifying that the proxy withhold from voting on a resolution.

The proxy position for each company (excluding the proxy votes carried from one meeting to the other meeting by the Special Voting Shares in accordance with the DLC structure) on the resolutions put to both Rio Tinto plc and Rio Tinto Limited shareholders under the joint electoral procedure was as follows:
