Letter from the Chair Dear shareholders, I am pleased to invite you to Rio Tinto Limited’s annual general meeting, which will be held at 9:30am (AEST) on Thursday, 2 May 2024 at the Grand Ballroom, the Hilton Brisbane, 190 Elizabeth Street, Brisbane, Queensland. This notice of meeting describes the business that will be proposed at the meeting and sets out the procedures for your participation and voting. Your participation in the annual general meeting is important to Rio Tinto and a valuable opportunity for the Board to discuss with shareholders the priorities and performance of the Group. Please note that only shareholders, proxy holders and corporate representatives in attendance at the meeting will be eligible to ask questions of the Directors. Those shareholders who are unable to attend the meeting in person can participate online. As announced late last year, Megan Clark retired from the Board in December 2023. I would like to express my sincere thanks to Megan for her significant contribution to Rio Tinto. We will greatly miss her insights and wise counsel. During 2023, we continued to refresh the composition of our Board as we seek to add new skills and experience. Over the course of 2023, we announced the appointments of five new Non-Executive Directors to the Board: Dean Dalla Valle and Susan Lloyd-Hurwitz joined the Board in June 2023, Joc O’Rourke in October 2023 and Martina Merz in February 2024. I am pleased to include resolutions to elect these Non-Executive Directors at the 2024 annual general meetings. Sharon Thorne will join the Board in July 2024 and will stand for election at the 2025 annual general meetings. We look forward to benefitting from our new Directors’ extensive experience and leadership in areas such as mining, metals, sustainability, operational excellence, and culture change. We believe it is important to retain the expertise and experience of our longer-serving Directors during the transitional period as newer Directors familiarise themselves with the Group. This is particularly important in terms of succession planning for Board Committee Chair roles. As part of that phased transition, Simon McKeon has agreed to step down as a Director at the conclusion of our annual general meetings in 2024, and will not therefore seek re-election by shareholders. I am extremely grateful to Simon for his invaluable contribution. Having regard for his roles as Rio Tinto Limited’s Senior Independent Director and the Designated Director for workforce engagement, Simon has taken a particular interest in Rio Tinto’s revitalised approach to engagement with the broader Australian community as well as the company’s cultural reset. On behalf of the Board, I wish him well for the future. Our new Board will therefore peak at 14 directors and then go back to a more optimal size. With these changes, the proportion of women on the Board is now 36% and this will rise to 43% following the commencement of Sharon Thorne’s appointment in July 2024. This year, the business of the meeting will also include a number of resolutions relating to remuneration. The first is the approval of the Remuneration Policy (the Policy), set out on pages 113-145 of the 2023 Annual Report (Resolution 2). Rio Tinto’s current remuneration policy was approved by shareholders at the 2021 annual general meeting and is now due for renewal. While the overall structure of the new Policy remains broadly unchanged from the policy previously approved by shareholders in 2021, the updates are aimed at strengthening the alignment between executive reward and the Group’s strategic priorities, simplifying our reward framework, and ensuring the level of compensation is positioned to attract, motivate and retain executive talent, in keeping with evolving corporate governance and market practice. In addition to the Policy resolution, we have the annual remuneration related resolutions relating to the approval of the Directors’ 2023 Remuneration Report (Resolutions 3 and 4) in accordance with the requirements under UK and Australian law respectively. The last of the remuneration related resolutions (Resolution 5) seeks approval to increase the annual maximum aggregate amount of remuneration payable to all Non-Executive Directors (Fee Cap) from £3,000,000 to £4,000,000 to allow for (among other things) market competitiveness, global economic conditions, inflation, and changes to the Board’s composition. The current annual maximum aggregate Fee Cap of £3,000,000 was approved by shareholders in 2009 and has remained unchanged for 15 years. The Fee Cap is a maximum limit only. We do not envisage that the annual maximum Fee Cap will need to be fully utilised based on current remuneration arrangements. We are also seeking to amend Rio Tinto Limited’s Constitution (Resolutions 22 and 23) in order to update certain provisions to reflect current best practice in Australia and to align with Rio Tinto plc’s Articles of Association, for consistency. Your Directors are unanimously of the opinion that all of the resolutions proposed in this notice are in the best interests of shareholders and of Rio Tinto as a whole. Accordingly, they recommend that you vote in favour of all of the resolutions, noting the Board’s interest in Resolution 5. Shareholders who are unable to participate in the meeting are strongly encouraged to complete and submit a proxy form by no later than 9:30am (AEST) on Tuesday, 30 April 2024 in line with the instructions on page 5. Submitting a proxy form will ensure your vote is recorded, but does not prevent you from participating and voting at the meeting either in person, or if you would like to do so online, as described on page 6. The corresponding Rio Tinto plc annual general meeting will take place in London on Thursday, 4 April 2024. The result of the votes on Resolutions 1 to 22 (inclusive), along with the results of the vote on Resolutions 23 and 24 at the Rio Tinto Limited annual general meeting, will be announced to the relevant stock exchanges and posted on our website after the end of the Rio Tinto Limited annual general meeting. I look forward to welcoming you to the annual general meeting and thank you for your continued support of Rio Tinto. Yours sincerely Dominic Barton Chair 21 February 2024 2 Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

If no proportion or number is specified, each proxy may exercise half the shareholder’s votes. Fractions of votes will be disregarded. The proxy form contains instructions for appointing two proxies. Directing your proxy how to vote If a shareholder wishes to indicate how their proxy should vote, mark the appropriate boxes on the proxy form.

Explanatory notes to the resolutions Resolution 1 Receipt of the 2023 Annual Report The Directors are required by company law to present the 2023 Annual Report comprising the 2023 financial statements, the Strategic Report, the Directors’ Report and the Auditors’ Report to the annual general meeting (AGM). These can be accessed at riotinto.com/annualreport. Resolution 2 Approval of the Remuneration Policy The current Remuneration Policy was put to, and approved by, shareholders of both Rio Tinto Limited and Rio Tinto plc at the 2021 AGMs. The proposed Remuneration Policy (the Policy) is provided on pages 119-126 of the 2023 Annual Report. It sets out the Group’s policy on remuneration and potential payments to Directors going forward. In accordance with UK law, the Policy must be approved by a binding shareholder vote (by means of a separate resolution) at least once every three years. Approving the Policy is considered a matter that affects the Group as a whole and will therefore be considered by shareholders of both Rio Tinto Limited and Rio Tinto plc. Once the Policy is approved, the Group will not be able to make a remuneration payment or payments for loss of office to a current Director that is outside the terms of the Policy, unless an amendment to the Policy has been approved by the shareholders. In that respect, the resolution is binding on Rio Tinto. If the resolution is passed, the Policy will take effect immediately. In accordance with UK law, a remuneration policy will be put to shareholders again at or before the 2027 AGMs or, if the resolution is not passed, at or before the 2025 AGMs (and, in that case, the current policy would continue in effect in the meantime). Resolution 3 Approval of the Directors’ Remuneration Report: Implementation Report The Implementation Report for the year ended 31 December 2023, comprising the Annual Statement by the People & Remuneration Committee Chair and the Implementation Report, is set out on pages 113-118 and 127-145 of the 2023 Annual Report. The Implementation Report describes the remuneration arrangements in place for each Executive Director, other members of the Executive Committee and the Non-Executive Directors (including the Chair) during 2023. The Annual Statement by the People & Remuneration Committee Chair provides context to 2023 remuneration outcomes, together with information to help shareholders understand what the executives were paid in 2023. This resolution is advisory and is required for UK law purposes. Resolution 4 Approval of the Directors’ Remuneration Report The Directors’ Remuneration Report for the year ended 31 December 2023 consists of the Annual Statement by the People & Remuneration Committee Chair, Remuneration at a glance – a summary of the Remuneration Policy, the Remuneration Policy and the Implementation Report. The Remuneration Report is set out on pages 113-145 of the 2023 Annual Report. This resolution is advisory and is required for Australian law purposes. Resolution 5 Increase to Non-Executive Directors’ Fee Cap In accordance with Rule 89(a) of the Company’s Constitution, Article 75(a) of Rio Tinto plc’s Articles of Association and ASX Listing Rule 10.17, shareholder approval is sought to increase the maximum aggregate amount available to be paid to the Company’s Non-Executive Directors as remuneration in any financial year (the Fee Cap). Under ASX Listing Rule 10.17, a listed entity must not increase the Fee Cap without shareholder approval. The current Fee Cap of £3,000,000 per annum was approved by shareholders at the 2009 AGM and it has remained unchanged during the past 15 years. It is proposed that the Fee Cap is increased by £1,000,000, from £3,000,000 to £4,000,000 per annum with effect from 1 March 2024. The Fee Cap is inclusive of any superannuation contributions and any travel allowances payable to Non-Executive Directors for attending Board and Committee meetings. The Fee Cap is a maximum limit only. It is intended to provide the Board with flexibility, subject to the Remuneration Policy, where applicable to procure the relevant skills and experience needed to deliver the Group’s strategy. The Board does not envisage that the increased Fee Cap will be exhausted annually based on current remuneration arrangements. Rio Tinto is seeking shareholder approval to increase the Fee Cap for the following reasons: – to ensure Rio Tinto maintains the ability to remunerate competitively and attract and retain high calibre Non-Executive Directors; – to allow for some growth in Non-Executive Directors’ remuneration to reflect market competitiveness, global economic conditions and high inflation. As provided for in the current Remuneration Policy, the Board approved increases to Non-Executive Directors’ remuneration with effect from 1 March 2024 as set out in the Remuneration Report on pages 139-140 of the 2023 Annual Report. The last increase to the Non-Executive Directors’ remuneration was in 2018; – to provide flexibility with Board and Committee appointments, so that the Board can appropriately manage potential new Director appointments in light of the mix of skills, experience and diversity on the Board to ensure that the Board is operating effectively, that any changes in composition are effected as smoothly as possible and that the Board continues to have the right balance of skills, knowledge and experience; and 7Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions – to provide for appropriate and coordinated Board succession planning and to increase the diversity of membership on the Board, which may require a temporary increase in the number of Non-Executive Directors during a transition period. The Board is continuing to review its composition to ensure that collectively the Non-Executive Directors provide the skillset appropriate to the scope and complexity of Rio Tinto’s business, including relevant industry and other professional experience, and specific geographical knowledge and understanding. During 2023, we announced the appointment of five new Non-Executive Directors to enhance the skills mix on the Board taking the number of Non-Executive Directors on the Board to 13. If shareholders approve this resolution, the Fee Cap will be increased to £4,000,000. The additional headroom that will be provided by this increase is seen as prudent to give the Board the necessary flexibility to continue operating effectively and manage succession planning. If this resolution is not approved, the aggregate Fee Cap will remain at £3,000,000 and the Board will not have this flexibility. No securities have been issued to any Non-Executive Director with the approval of the shareholders under ASX Listing Rules 10.11 or 10.14 within the last three years. Resolutions 6–18 Election and re-election of Directors The Board has adopted a policy, whereby all Directors are required to seek re-election by shareholders on an annual basis. Accordingly, other than those Directors seeking election for the first time, all continuing Directors will retire and offer themselves for re-election. Simon McKeon will step down from the Board at the conclusion of the Company’s AGM and therefore will not be seeking re-election. Rio Tinto appointed Dean Dalla Valle and Susan Lloyd-Hurwitz with effect from 1 June 2023, Joc O’Rourke from 25 October 2023 and Martina Merz from 1 February 2024. These Non-Executive Directors will seek election for the first time. Rio Tinto has satisfactorily undertaken checks into these Non-Executive Directors’ backgrounds and experience prior to appointment. These new appointments will enhance the overall expertise and skills mix on the Board. More generally, the Board is of the view that all of the Directors seeking election or re-election continue to be effective and their contribution supports the long-term sustainable success of the Company. Each Director demonstrates the level of commitment required in connection with their role and the needs of the business (including making sufficient time available for Board and committee meetings and other duties). The skills and experience of each Director, which can be found below and on pages 92-93 of the 2023 Annual Report, demonstrate why their contribution is, and continues to be, important to Rio Tinto’s long-term sustainable success. The Board has also adopted a framework on Directors’ independence and is satisfied that each Non-Executive Director standing for election or re-election at the meeting is independent in accordance with this framework. Biographical details in support of each Director’s election or re-election are provided below. Dean Dalla Valle Independent Non-Executive Director, MBA. Age 64. Appointed June 2023.

Explanatory notes to the resolutions Ben Wyatt Independent Non-Executive Director, LLB, MSc. Age 49. Appointed September 2021. Member of Audit & Risk Committee and Nominations Committee. Skills and experience: Ben had a prolific career in the Western Australian Parliament before retiring in March 2021. He held a number of ministerial positions and became the first Indigenous treasurer of an Australian parliament. His extensive knowledge of public policy, finance, international trade and Indigenous affairs brings valuable insight and adds to the depth of knowledge on the Board. Ben was previously an officer in the Australian Army Reserves, and went on to have a career in the legal profession as a barrister and solicitor. Current external appointments: Non-Executive Director of Woodside Energy Ltd, APM Human Services International Limited, Telethon Kids Institute and West Coast Eagles. Member of the Advisory Committee of Australian Capital Equity. Ben is recommended for re-election. Resolutions 19-20 Re-appointment and remuneration of auditors Under UK law, the shareholders are required to approve the appointment of Rio Tinto plc’s auditor each year. The appointment runs until the conclusion of Rio Tinto’s 2025 AGMs. Under Rio Tinto’s DLC structure, the appointment of Rio Tinto plc’s auditors is a Joint Decision Matter and has therefore been considered by Rio Tinto Limited and Rio Tinto plc shareholders at each AGM since the DLC structure was established in 1995. On recommendation of the Audit & Risk Committee, the Board proposes the re-appointment of Rio Tinto plc’s current auditors. KPMG LLP have expressed their willingness to continue in office for a further year. In accordance with UK company law and good corporate governance practice, shareholders are also asked to authorise the Audit & Risk Committee to determine the auditors’ remuneration. Resolution 21 Authority to make political donations Under UK law there is a prohibition against making political donations without authorisation of a company’s shareholders in a general meeting. The authority being sought is not proposed or intended to alter Rio Tinto’s policy of not making political donations, within the normal meaning of that expression. However, the definitions of political donation, political expenditure and/or political organisation in the UK Companies Act are defined very widely. Because of this, it may be that some of Rio Tinto’s activities could fall within this definition and, without the necessary authorisation, Rio Tinto’s ability to communicate its views effectively to political audiences and to relevant interest groups could be inhibited. In particular, the definition of political organisations may extend to bodies such as those concerned with policy review, law reform, the representation of the business community and special interest groups, such as those concerned with the environment. As a result, the definition may cover legitimate business activities that would not, in the ordinary sense, be considered to be political donations or political expenditure. The authority that the Board is requesting is a precautionary measure to ensure Rio Tinto does not inadvertently breach the UK Companies Act. In accordance with the United States Federal Election Campaign Act, Rio Tinto provides administrative support for the Rio Tinto America Political Action Committee (PAC). The PAC was created in 1990 and encourages voluntary employee participation in the political process. All Rio Tinto America PAC employee contributions are reviewed for compliance with federal and state law and are publicly reported in accordance with US election laws. The PAC is controlled by neither Rio Tinto nor any of its subsidiaries but instead by a governing board of five employee members on a voluntary basis. In 2023, contributions to Rio Tinto America PAC by 12 employees amounted to US$10,425, and Rio Tinto America PAC donated US$17,500 in political contributions in 2023. Accordingly, the Directors believe that supporting the authority sought in this resolution is in the interests of shareholders. Any expenditure that may be incurred under this authority will be disclosed in next year’s Annual Report. Details of political expenditure by Rio Tinto during the past year are set out on page 150 in the 2023 Annual Report. Words and expressions used in Resolution 21 that are defined in Part 14 of the UK Companies Act shall have the same meanings for the purposes of Resolution 21. Resolution 22 Amendments to Rio Tinto Limited’s Constitution – approval of amendments that constitute Class Rights Actions It is proposed in Resolution 22 to amend the Constitution of Rio Tinto Limited (the Current RTL Constitution). The proposed updates reflect minor changes in market practice and Australian legal requirements. An explanation of the intended purpose and effect of the adoption of the principal changes that are proposed in Resolution 22 is set out in the table in Appendix 1 of this notice of meeting. Other changes that are of a minor, technical or clarifying nature, or that are incidental to these principal changes, have not been noted in the table. The changes proposed under Resolution 22 are being proposed separately to those proposed under Resolution 23 (which will be voted on by Rio Tinto Limited shareholders only). This is because the changes proposed in Resolution 22 relate to “entrenched provisions” in the Current RTL Constitution and therefore constitute a Class Rights Action under the Current RTL Constitution. Resolution 22 is proposed as a Class Rights Action under the Current RTL Constitution, which requires approval by the requisite majority of shareholders of each of Rio Tinto plc and Rio Tinto Limited. 11Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions In contrast, the changes proposed in Resolution 23 do not constitute a Class Rights Action under the Current RTL Constitution. Accordingly, Resolution 23 will be voted on by Rio Tinto Limited shareholders only. A copy of the Current RTL Constitution marked to show the changes being proposed in Resolution 22 and Resolution 23, is available for inspection, as noted on page 6 of this notice. The changes proposed in Resolution 22 are marked in green text and the changes proposed in Resolution 23 are marked in blue text in the document (the Amended RTL Constitution) that has been produced to the meeting (which is for the purpose of identification marked “A” and initialled by the Chair). Subject to the passing of the relevant resolutions by Rio Tinto plc and Rio Tinto Limited shareholders, the Amended RTL Constitution will become effective as of the close of the 2024 AGM of Rio Tinto Limited. Resolution 23 Amendments to Rio Tinto Limited’s Constitution – general updates and changes Along with the changes to the Current RTL Constitution proposed in Resolution 22, certain additional amendments to the Current RTL Constitution are proposed in Resolution 23. The proposed updates reflect changes in market practice and legal and regulatory requirements, including with respect to voting and conduct of general meetings by means of electronic facilities. An explanation of the intended purpose and effect of the adoption of the principal changes that are proposed is set out in the table in Appendix 2 of this notice of meeting. Other changes that are of a minor, technical or clarifying nature have not been noted in the table. A copy of the Current RTL Constitution marked to show the changes being proposed in Resolution 22 and Resolution 23 (being the Amended RTL Constitution), is available for inspection, as noted on page 6 of this notice. The changes proposed in Resolution 22 are marked in green text and the changes proposed in Resolution 23 are marked in blue text in the document that has been produced to the meeting (which is for the purpose of identification marked “A” and initialled by the Chair). Subject to the passing of the relevant resolutions by Rio Tinto Limited shareholders, the Amended RTL Constitution will become effective as of the close of the 2024 AGM of Rio Tinto Limited. Resolution 24 Renewal of on-market share buy-back authority The Board is seeking shareholder approval to buy back Ordinary Shares during the period until the 2025 AGM or 1 May 2025 inclusive (whichever is the later) on-market, but subject to the cap set out below. The Board continually assesses the Company’s capital structure to ensure it has an effective and appropriate balance. The Company’s ability to return surplus capital to shareholders in an efficient and effective manner will be enhanced by the approval of this resolution, which will provide the Company with the flexibility to undertake an on-market buy-back where shareholder approval is required. Such authority would expire if a new buy-back approval is given by shareholders, and in any event is in addition to Rio Tinto Limited’s ability to undertake buy-backs under the Australian Corporations Act, where shareholder approval is not required. On-market buy-backs allow Rio Tinto Limited to buy back shares over time, depending on market conditions and prices. Any such on-market buy-backs would occur in accordance with the Listing Rules of the ASX from time to time. Currently the Listing Rules state that the price at which Rio Tinto Limited buys back Ordinary Shares on market must not be more than 5% above the average market price (as that term is defined in those Listing Rules) of Ordinary Shares calculated over the last five days on which sales were recorded on the ASX prior to the day on which shares are to be bought back. Should the Board decide to proceed with on-market buy-backs authorised under this resolution, such buy-backs would only occur if the Board believes that they could be undertaken without prejudicing the Group’s ability to maintain its dividend policy. The Board does not consider that any such buy-backs would pose any significant disadvantage to shareholders. Size of any buy-backs The authority sought by this resolution permits Rio Tinto Limited to buy back Ordinary Shares on market up to a limit of 55.6 million Ordinary Shares. This number represents approximately 15% of the 371,216,214 Ordinary Shares on issue in the capital of Rio Tinto Limited as at 13 February 2024, being the latest practicable date for information to be included in this notice (the Latest Practicable Date). Subject to the above limit, the number of Ordinary Shares to be bought back (if any) will be determined by the Directors. Financial impact on Rio Tinto Limited The consideration paid under any on-market buy-backs undertaken pursuant to this resolution would be cash and all Ordinary Shares bought back by Rio Tinto Limited would be cancelled. No decision has been made as to how any future buy-backs would be funded. The Board only intends to proceed with such buy-backs and fund them by debt if the funding required for any such buy-backs would be within the debt capacity of the Group and so would not be expected to have any adverse effect on existing operations or current investment plans. By way of illustration, the purchase of ordinary shares in the Company with a total value of A$1 billion at exchange rates prevailing on 31 December 2023 would (if funded by debt), increase the Group’s net debt and reduce equity attributable to shareholders by US$686 million and, on the basis of the Group’s 2023 financial statements, would increase the ratio of net debt to total capital by 1.1 percentage points, from 7.0% to approximately 8.1%. If they proceed, the precise impact of any buy-backs would not be known until they are completed, as this would depend on market prices, the number of Ordinary Shares repurchased and the timing of the repurchases. 12 Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions Effect on control Under any on-market buy-back by Rio Tinto Limited, the percentage of shares bought back from a shareholder would depend on the number they seek to sell, the price at which they offer to sell and the number of shares Rio Tinto Limited buys back. Given the maximum aggregate size of any buy-backs authorised under Resolution 24, they would not be expected to have any change of control implications for Rio Tinto Limited or the Group. On its own, an on-market buy-back by Rio Tinto Limited would reduce the number of Ordinary Shares in Rio Tinto Limited on issue as a proportion of the total number of ordinary shares on issue in the Group (that is, the ordinary shares on issue in Rio Tinto Limited and in Rio Tinto plc combined). However, the buy-back of Rio Tinto plc ordinary shares would also reduce the number of Rio Tinto plc ordinary shares on issue. Given the limit on the size of the buy-backs permitted under the authority being sought, the Board believes that even if there is a change in this proportion, it would not have any material impact on the control of the Group or on the relative voting power of the shareholders in each of Rio Tinto Limited or Rio Tinto plc. Other information Share price information The closing price of Rio Tinto Limited’s Ordinary Shares on the ASX on 13 February 2024 (being the Latest Practicable Date) was A$129.00. The highest and lowest closing prices and the average closing prices for the Ordinary Shares on the ASX during each of the prior four months were as follows: Month Lowest closing price A$(a) Highest closing price A$(a) Average closing price A$(b) February 2024 (to 13 February 2024) 128.41 132.00 129.83 January 2024 126.54 135.66 130.49 December 2023 124.91 136.29 130.91 November 2023 119.37 127.76 123.64 (a) Based on the closing prices of the Company’s ordinary shares on the ASX for each trading day over the relevant month. (b) Calculated as the average of the closing prices of the Company’s ordinary shares on the ASX for each trading day over the relevant month. Australian tax considerations On-market buy-back If Rio Tinto Limited were to undertake an on-market buy-back, all of the price paid to shareholders to buy back their Ordinary Shares would, for Australian taxation purposes, be treated as consideration in respect of the sale of their shares. As such, no part of the price paid would be treated as a deemed dividend and so for a vendor shareholder, the disposal would be treated in the same way as any other disposal of shares on-market by the shareholder. For Rio Tinto Limited, the effect of an on-market buy-back may be to reduce its available franking credits, even though no part of the price paid to shareholders will be treated as a deemed dividend for tax purposes. General comments While on-market buy-backs by Rio Tinto Limited may result in a reduction of available franking credits, the Board would only undertake such buy-backs where it believed that they would not prejudice Rio Tinto Limited’s ability to fully frank its dividends for the reasonably foreseeable future. Capital management programme As in previous years, and to facilitate the Group’s ongoing capital management programme, Rio Tinto plc shareholder approval will be sought to renew the authority for Rio Tinto plc and Rio Tinto Limited (or any of its subsidiaries) to make on-market purchases of shares in Rio Tinto plc. This includes the authority to allow shares in Rio Tinto plc purchased by Rio Tinto Limited (or any of its subsidiaries) to be repurchased by Rio Tinto plc on the terms set out in an agreement approved by Rio Tinto plc’s shareholders and for those shares to be cancelled. If Rio Tinto Limited (or any of its subsidiaries) were to purchase Rio Tinto plc shares on-market it would sell them to Rio Tinto plc for cancellation. From the perspective of the Group’s cash and gearing, whether Rio Tinto plc shares are bought back directly by Rio Tinto plc, or bought by Rio Tinto Limited and sold to Rio Tinto plc, is not material, as the latter of these transactions is internal to the Group. If a nominal price were paid by Rio Tinto plc for any shares bought from Rio Tinto Limited, it would result in a reduction of Rio Tinto Limited’s retained earnings (to the extent of any difference between the price paid for the shares by Rio Tinto Limited and the sale price of those shares to Rio Tinto plc). However, the Directors would only proceed if they were confident they could do so without prejudicing Rio Tinto Limited’s ability to maintain its dividend policy and to continue to be in a position to fully frank its dividends for the foreseeable future. No new Ordinary Shares in Rio Tinto Limited have been issued since July 2009. However, to retain additional flexibility in the conduct of its capital management initiatives, the Board may consider issuing new shares in connection with employee share and incentive plans. 13Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

Appendix 1 – Summary of the principal proposed changes under Resolution 22 Proposed Change Key Relevant Rule(s) in RTL Constitution Reason for Change Amendments to clarify definition of ‘members present’ Rule 2(a)(xlv) Consequential amendment to Rule 62 It is proposed that the definition of ‘members present’ (and correspondingly, ‘member present’) in the Current RTL Constitution be amended to expressly include members who may attend and participate at a general meeting by means of technology, which is aligned with Rules 57 and 57A. Under the Current RTL Constitution, the definition of ‘members present’ does not expressly include members who may attend a general meeting using technology. The proposed amendments clarify that members attending and participating in a general meeting via technology (in a Hybrid Meeting) classify as ‘members present’, including for the purposes of the provisions regarding quorum and voting. Updating provisions regarding voting using polls consistent with the Australian Corporations Act Rule 70 Under the Current RTL Constitution, all questions are voted on a show of hands, unless a poll is properly required or demanded, in accordance with the Current RTL Constitution. The Amended RTL Constitution reflects changes to the Australian Corporations Act, which require resolutions proposed in a notice of meeting and members’ resolutions to be decided on a poll (and not a show of hands). The proposed amendments provide expressly that resolutions proposed in a notice of meeting and members’ resolutions are to be decided on a poll (in addition to the existing provisions which provide when a poll may be properly demanded in accordance with other provisions of the Current RTL Constitution), rather than a show of hands. Amendments to remove references to facsimile Rules 76, 108, 133 and 136 It is proposed to remove all references to facsimile which appear in the Current RTL Constitution. Facsimile is rarely used as a means of communication in the present day. Removing references to facsimile but retaining broader references to electronic means of communication provides flexibility for the Amended RTL Constitution to reflect communications currently used. 14 Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

Appendix 2 – Summary of the principal proposed changes under Resolution 23 Proposed Change Key Relevant Rule(s) in RTL Constitution Reason for Change Updating provisions regarding number of Joint Holders consistent with CHESS Replacement system Rule 14(a) It is proposed that the Current RTL Constitution be amended to increase the potential maximum number of persons who can be registered as joint holders of a share from three persons to four persons. Under the Current RTL Constitution, Rio Tinto Limited is not bound to register any more than three persons as joint holders of a share. The ASX has announced that it intends to replace its existing CHESS system (being the ASX’s system that, among other things, clears and settles trades in Australia’s equity markets and maintains a CHESS sub-register of security holdings). One change that the ASX has foreshadowed with the CHESS replacement system is that it will allow for up to four joint holders of a share. The proposed amendments would allow Rio Tinto Limited to register up to four persons as joint holders, in alignment with the proposed CHESS replacement system. Amendments to clarify the ability to require payment of any third party fees in connection with transfer or registration of, or the settlement of transactions effecting, securities Rule 33(d) It is proposed that the Current RTL Constitution be amended to include a new rule that, subject to law, a shareholder may be charged a transfer fee by a third party service provider in connection with the transfer or registration of, or the settlement of transactions affecting, securities of Rio Tinto Limited. The Current RTL Constitution is silent on this matter. Rio Tinto Limited’s share registry, Computershare Investor Services Pty Ltd, currently charges a transfer fee for the services that it provides in connection with an off-market transfer of a share in Rio Tinto Limited. Historically, this fee has been absorbed by Rio Tinto Limited. In the event of an off-market share transfer, the proposed amendments would expressly allow the transfer fee to be charged by a third party service provider to a shareholder. The Current RTL Constitution does not currently permit Rio Tinto Limited or a third party service provider to charge a transfer fee to shareholders. Updating provisions regarding use of electronic facilities in general meetings consistent with the Australian Corporations Act Rules 57(c)(i), 57A(a), 57A(c) It is proposed that the Current RTL Constitution be amended to clarify that the participation of members in a general meeting via technology is to be in accordance with applicable law. In circumstances where technology is utilised in a general meeting, s249S(7) of the Australian Corporations Act requires that technology be reasonable and allow members as a whole to exercise any rights to ask questions and make comments. Under the Current RTL Constitution, where technology is used in a general meeting, the Chair must be satisfied adequate facilities are available throughout the meeting to ensure members attending via technology are able to participate in the meeting. The proposed amendments aim to clarify that the Chair must also be satisfied that adequate facilities are available throughout the meeting to ensure members attending via technology are able to participate in the meeting in accordance with the applicable law (such as that set out in s249S of the Australian Corporations Act). 15Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com

Appendix 2 – Summary of the principal proposed changes under Resolution 23 Proposed Change Key Relevant Rule(s) in RTL Constitution Reason for Change Amendments to facilitate technology neutral signing of proxy forms Rule 78 It is proposed that the Current RTL Constitution be amended to allow proxy forms to be signed by electronic means in accordance with the law. Under the Current RTL Constitution, proxy forms may be in electronic form and may be signed by any method authorised by the Board and permitted by the Australian Corporations Act. Recent changes to the Australian Corporations Act permit a person to sign an electronic form of a document using electronic means, provided the method of signing identifies the person, indicates the person’s intention in respect of the information recorded in the document, and is reliable as appropriate for the purposes for which the information was recorded. The proposed amendments will allow members to sign a proxy form by electronic means in accordance with the law, without requiring Board authorisation, whilst retaining the flexibility for the Board to authorise any other method for signing (provided any such method is also permitted by law). Amendments to provide Board discretion to declare, determine or pay dividends in any currency Rule 118(c) It is proposed that the Current RTL Constitution be amended to provide the Board with greater flexibility as to which currency dividends are declared, determined and paid. Under the Current RTL Constitution, the Board must declare or determine a dividend in Australian currency, but may determine to pay the dividend in any currency or currencies other than Australian currency. The proposed amendments would provide the Board with the flexibility to declare or determine (as well as pay) dividends in any currency or currencies. The proposed amendments would bring the Amended RTL Constitution in line with the Current Rio Tinto plc Articles of Association, which provide a broad discretion to the Directors to pay dividends and the terms on which those dividends may be paid. Where shareholders currently receive payment in accordance with existing currency elections or payment arrangements (e.g., Australian resident shareholders who receive payment in Australian dollars), Rio Tinto Limited intends to continue to pay dividends in accordance with those arrangements, using the exchange rate prevailing as at the currency conversion date, which is 5 business days before the date of payment. 16 Rio Tinto Limited 2024 Notice of annual general meeting | riotinto.com
