Letter from the Chair Dear shareholders, I am pleased to invite you to Rio Tinto plc’s annual general meeting, which will be held at 11:00am on Thursday, 4 April 2024 at The Queen Elizabeth II Conference Centre, Broad Sanctuary, Westminster, London SW1P 3EE. 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 place 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. We are also seeking to amend Rio Tinto Limited’s Constitution (Resolution 22) 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 11:00am on Tuesday, 2 April 2024 in line with the instructions on page 17. 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 15–16. The corresponding Rio Tinto Limited annual general meeting will take place in Brisbane on Thursday, 2 May 2024. The result of the votes on Resolutions 1 to 22 (inclusive), which are also being proposed to the Rio Tinto Limited annual general meeting, will be determined when the relevant polls are closed at the end of the Rio Tinto Limited meeting. The results of the polls on these resolutions will be announced to the relevant stock exchanges and posted on our website after that date. The result of the polls on Resolutions 23 to 26 (inclusive), which only apply to Rio Tinto plc, will be released as soon as possible after the Rio Tinto plc 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 plc 2024 Notice of annual general meeting | riotinto.com

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 Rio Tinto Limited’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 AGMs 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 6 Rio Tinto plc 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 Rio Tinto Limited 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.

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 in a different resolution which will be voted on by Rio Tinto Limited shareholders only (which can be found at Resolution 23 of Rio Tinto Limited’s Notice of Annual General Meeting 2024 dated 21 February 2024). 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 and the Rio Tinto plc Articles of Association. 10 Rio Tinto plc 2024 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions 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. In contrast, the changes proposed in Resolution 23 of Rio Tinto Limited’s Notice of Annual General Meeting 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 is available for inspection, as noted on page 13 of this notice. The changes proposed in Resolution 22 are marked in green text and the changes proposed in the separate resolution that will be voted on by Rio Tinto Limited shareholders only (which can be found at Resolution 23 of Rio Tinto Limited’s Notice of Annual General Meeting 2024 dated 21 February 2024) 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 General authority to allot shares Under section 551 of the Companies Act, the Directors may only allot shares or grant rights to subscribe for, or convert any security into, shares if authorised to do so by shareholders. This resolution would give the Directors the authority to allot new shares, and grant rights to subscribe for, or convert other securities into shares, up to an aggregate nominal amount equal to £41,713,922 (representing 417,139,228 ordinary shares of 10p each). This amount represents not more than one third of the total issued ordinary share capital of the Company, exclusive of treasury shares, as at 13 February 2024, the latest practicable date prior to publication of this notice (the Latest Practicable Date). For the avoidance of doubt this resolution does not seek authority to allot new shares in connection with a rights issue up to a further (second) one third of the total issued ordinary share capital of the Company. At the Latest Practicable Date, the Company held 4,485,902 treasury shares, which represents 0.36% of the total number of the Company’s ordinary shares in issue, excluding treasury shares, at that date. The authority sought under this resolution, if approved, will expire at the end of the AGM of the Company held in 2025 (or, if earlier, at the close of business on 30 June 2025) unless renewed, varied or revoked by the Company in general meeting. The Directors have no present plans to exercise authority sought under this resolution, except in connection with employee share and incentive plans. The Directors consider it desirable, however, to have flexibility, as permitted by corporate governance guidelines, to manage the Group’s capital resources. Resolution 24 Disapplication of pre-emption rights The Directors are also seeking authority to allot new shares (and other equity securities), or sell treasury shares, for cash without first offering them to existing shareholders in proportion to their existing holdings. The authority granted under this resolution would be limited to: (a) where the Company undertakes a pre-emptive offer by way of an open offer or rights issue, then the Directors may make exclusions or other arrangements in order to deal with treasury shares, fractional entitlements or legal or practical problems arising under the laws of any overseas jurisdiction, or the requirements of any recognised regulatory body or stock exchange, or other matters; or (b) otherwise up to an aggregate nominal amount of £8,113,169 (representing 81,131,694 ordinary shares of 10p each). As historically agreed with the Association of British Insurers (the precursor body to the Investment Association), this aggregate amount represents not more than 5% of the combined issued ordinary share capital of the Company and Rio Tinto Limited (exclusive of shares held in treasury by the Company) as at the Latest Practicable Date. If Resolution 24 is passed, the authority will expire at the end of the AGM of the Company held in 2025 (or, if earlier, at the close of business on 30 June 2025) unless renewed, varied or revoked by the Company in general meeting. For the avoidance of doubt, we are not this year seeking approval for the increased level of disapplication of pre-emption rights published by the Pre-emption Group on 4 November 2022 or approval for a separate additional authority in respect of acquisitions or specified capital investments. Resolution 25 Authority to purchase Rio Tinto plc shares Consistent with its practice in prior years, the Board is seeking authority to buy back shares in the Group. The overall purpose of the buy-back resolutions of the Company and Rio Tinto Limited is to provide the Group with flexibility in the conduct of its capital management initiatives, whether through on- or off-market share buy-backs in either or both of the Company and/or Rio Tinto Limited. The Directors have no current intention to exercise the authority conferred pursuant to Resolution 25, and would only intend to do so when that would be in the best interests of the Company and its shareholders. The authority conferred by the resolutions to be approved at the Company’s and Rio Tinto Limited’s 2024 AGMs would allow buy-backs of ordinary shares in the Company, either by the Company on-market or by Rio Tinto Limited (or a subsidiary of Rio Tinto Limited) on-market, and buy-backs by Rio Tinto Limited of its ordinary shares, either under off-market buy-back tenders or on-market. In 2023, there were no capital management share purchase programmes. 11Rio Tinto plc 2024 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions Under the DLC agreements, the approval for a buy-back of the Company’s ordinary shares, whether by the Company or by Rio Tinto Limited (or a subsidiary of Rio Tinto Limited), is voted on by the Company’s shareholders only. Similarly, the approval for Rio Tinto Limited to buy back its ordinary shares is voted on by Rio Tinto Limited shareholders only. These approvals were most recently renewed at the 2023 AGMs and expire on the date of the 2024 AGMs. Authority is sought for the Company, Rio Tinto Limited and/or any of Rio Tinto Limited’s subsidiaries, to purchase up to 10% of the issued ordinary share capital of the Company during the period stated below. The authority will expire at the end of the AGM of the Company held in 2025 (or, if earlier, at the close of business on 30 June 2025). The authority sought would permit the Company, Rio Tinto Limited and/or any of Rio Tinto Limited’s subsidiaries to purchase up to 125,141,768 of the Company’s ordinary shares, representing approximately 10% of its issued ordinary share capital, excluding the shares held in treasury, as at the Latest Practicable Date. The maximum price that may be paid for an ordinary share (exclusive of expenses) is an amount equal to the higher of: (a) 5% above the average of the middle market quotations for an RTP Ordinary Share as derived from the London Stock Exchange Daily Official List during the period of five business days immediately prior to the day on which such share is contracted to be purchased; or (b) the higher of the price of the last independent trade and the highest current independent bid on the trading venue where the purchase is carried out. The minimum price that may be paid for an ordinary share (exclusive of expenses) is its nominal value. By way of illustration, the purchase of ordinary shares in the Company with a total value of US$500 million 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$500 million and, on the basis of the Group’s 2023 financial statements, would increase the ratio of net debt to total capital by 0.8 percentage points, from 7.0% to approximately 7.8%. The total number of outstanding employee share awards at the Latest Practicable Date was 4,132,743, which represents 0.33% of the issued ordinary share capital, excluding the shares held in treasury at that date. This excludes options and awards that the Company intends to settle without the issue of new shares or the sale of treasury shares. If the Company were to buy back the maximum number of shares permitted pursuant to this resolution, then this number of options and awards would represent 0.37% of the issued ordinary share capital, excluding the shares held in treasury. Pursuant to the Companies Act, the Company can hold the ordinary shares that have been repurchased itself as treasury shares and resell them for cash, cancel them (either immediately or at a point in the future) or use them for the purposes of its employee share plans. Whenever any ordinary shares are held as treasury shares, all dividend and voting rights on these shares are suspended. Any shares purchased under the authority, if approved, would be cancelled. The authority being sought in paragraph (a) of Resolution 25 extends to Rio Tinto Limited and/or any of its subsidiaries. Any purchase by the Company from Rio Tinto Limited (or such subsidiaries) of the Company’s ordinary shares would be an off-market purchase and the Companies Act requires the terms of any proposed contract for an off-market purchase to be approved by a special resolution of the Company before the contract is entered into. Such approval is sought in paragraph (b) of Resolution 25. The Company is seeking the approval of shareholders for such off-market purchases from Rio Tinto Limited and/or any of its subsidiaries as may take place to be made at a price not less than one penny per parcel of shares. It is expected that such purchases would occur for nominal consideration. It is immaterial to the shareholders of either the Company or Rio Tinto Limited if Rio Tinto Limited or any of Rio Tinto Limited’s subsidiaries make a gain or a loss on such transactions as they have no effect on the Group’s overall resources. The underlying purpose of these transactions would be to facilitate any capital management programme that the Group may be implementing at the relevant time, with the intention of returning surplus cash to shareholders in the most efficient manner. The DLC Merger Sharing Agreement contains the principles of equalisation, which ensure that entitlements to distributions of income and capital will be the same for all continuing shareholders regardless of whether the Company’s or Rio Tinto Limited’s shares are purchased or whether the Company, Rio Tinto Limited or a subsidiary of Rio Tinto Limited acts as the purchaser. Rio Tinto Limited will also seek to renew its shareholder approval to buy back its own ordinary shares at its 2024 AGM on 2 May 2024. Resolution 26 Notice period for general meetings other than annual general meetings Changes made to the Companies Act by the Companies (Shareholder Rights) Regulations 2009 (the Regulations) increased the notice period required for general meetings of the Company to 21 days, unless shareholders approve a shorter notice period, which cannot, however, be less than 14 clear days. AGMs will continue to be held on at least 21 clear days’ notice. Before the Regulations came into force on 3 August 2009, the Company was able to call general meetings, other than an AGM, on 14 clear days’ notice without obtaining such shareholder approval. To preserve this ability, the Company has sought and obtained the required shareholder approval at each AGM since 2009. Resolution 26 seeks to renew this approval. The approval will be effective until the Company’s AGM in 2025, when it is intended that a similar resolution will be proposed. The shorter notice period would not be used as a matter of routine for such meetings but only where the flexibility is merited by the business of the meeting and is thought to be to the advantage of shareholders as a whole. 12 Rio Tinto plc 2024 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions Total voting rights As at the Latest Practicable Date, the total number of issued ordinary shares in the Company is 1,255,903,587 ordinary shares of 10p each, each with one vote. 4,485,902 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 1,251,417,685, which is used to calculate the approval thresholds for sole decision matters. The voting arrangements for shareholders under the Group’s DLC structure, including in respect of Joint Decision Matters, are explained in the shareholder information section of the 2023 Annual Report. Documents available for inspection The following documents will be available at the registered office of the Company from the date of this notice until the close of the Rio Tinto Limited AGM on 2 May 2024 (and, also at the place of the meeting from at least 15 minutes prior to and during the meeting until its conclusion): (a) proposed form of contract between Rio Tinto plc and Rio Tinto Limited and/or any of its subsidiaries for the purchase off-market of ordinary shares issued by the Company; (b) copies of Directors’ service contracts and letters of appointment with Rio Tinto Group companies; and (c) a copy of the Current RTL Constitution marked to show the changes being proposed in Resolution 22. 13Rio Tinto plc 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 (as permitted by the Australian Corporations Act, 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 plc 2024 Notice of annual general meeting | riotinto.com

A member may appoint more than one proxy in relation to the meeting provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that member. A member may only appoint a proxy or proxies by the methods specified in this notice. Members entitled to vote will be provided with a proxy form. To be effective the proxy form and any power of attorney or other written authority under which it is executed (or a notarially certified copy of any such authority) must reach the transfer office of the Company at Computershare Investor Services PLC, The Pavilions, Bridgwater Road, Bristol, BS99 6ZZ by 11:00am on 2 April 2024 or not less than 48 hours before the time of the meeting or adjourned meeting or (in the case of a poll taken otherwise than at or on the same day as the meeting or adjourned meeting) the taking of the poll at which it is to be used. Completion and return of the proxy form will not prevent a member from participating and voting at the meeting themselves (and shareholders are referred to pages 15–16 for details of how to participate in the AGM online). For further information please refer to your proxy form. If you do not have a proxy form and believe that you should have one, or if you require additional forms, please contact our registrar using the details set out on the final page of this notice of meeting. Proxy lodgement online Shareholders can also lodge their proxy forms online at: www.investorcentre.co.uk/eproxy and follow the prompts. To use this facility you will need the Control Number together with your Shareholder Reference Number (SRN) and PIN as shown on the proxy form. You will be deemed to have signed the proxy form if you lodge it in accordance with the instructions on the website and by the latest time for receipt of proxy appointments specified under the heading “Appointment of proxies” above. Proxy lodgement via CREST CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST Manual on the Euroclear website (euroclear.com). CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf. For a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a CREST Proxy Instruction) must be properly authenticated in accordance with the specifications of Euroclear UK & Ireland Limited and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by Computershare Investor Services PLC (ID 3RA50) by the latest time for receipt of proxy appointments specified under the heading “Appointment of proxies” above. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Application Host) from which Computershare Investor Services PLC (or any other agent of the company) is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means. CREST members and, where applicable, their CREST sponsor or voting service provider(s) should note that Euroclear UK & Ireland Limited does not make available special procedures in CREST for any particular message. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s), to procure that their CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. The Company and/or its agents may treat as invalid a CREST Proxy Instruction in the circumstances set out in regulation 35(5) (a) of the Uncertificated Securities Regulations 2001. 18 Rio Tinto plc 2024 Notice of annual general meeting | riotinto.com

Any person to whom this notice is sent who is a person nominated under section 146 of the Companies Act to enjoy information rights (a Nominated Person) may, under an agreement between them and the shareholder by whom they were nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, they may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights. The statement of the rights of shareholders in relation to the appointment of proxies in the section headed “Appointment of proxies” above does not apply to Nominated Persons. The rights described in that paragraph can only be exercised by shareholders of the Company. Corporate representative and nominated persons right to ask questions Any member, proxy or corporate representative participating in the meeting has the right to ask questions. The Company will answer questions relating to the business being dealt with at the meeting, but may choose not to answer if: (a) to do so would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information; (b) the answer has already been given on a website in the form of an answer to a question; or (c) it is undesirable in the interests of the Company or the good order of the meeting that the question be answered. Guests will not be permitted to ask questions. 4.

The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with section 527 or 528 (requirements as to website availability) of the Companies Act. Where the Company is required to place a statement on a website under section 527 of the Companies Act, it must forward the statement to the Company’s auditors not later than the time when it makes the statement available on the website. The business that may be dealt with at the AGM includes any statement that the Company has been required under section 527 of the Companies Act to publish on a website. 19Rio Tinto plc 2024 Notice of annual general meeting | riotinto.com
