Letter from the Chair Dear shareholders, I am pleased to invite you to Rio Tinto plc’s annual general meeting (AGM), which will be held at 11:00am on Thursday, 3 April 2025 at The Queen Elizabeth II Centre, Broad Sanctuary, Westminster, London SW1P 3EE. This notice of meeting describes the business that will be proposed at the AGM and sets out the procedures for your participation and voting. Your participation is highly valued and an important opportunity for the Rio Tinto’s Board and shareholders to discuss the Group’s priorities and performance. Please note that only shareholders, proxy holders and corporate representatives in attendance at the meeting, either in person or online, will be eligible to ask questions of the Directors. Board changes As we reported last year, the size of the Board peaked at 14 Directors as we retained the expertise and experience of our longer-serving Directors during a transitional period as newer Directors familiarised themselves with the Group. That transitional phase is now largely concluded so we will make the following changes to the Board during 2025. At the conclusion of the Rio Tinto Limited AGM in May 2025, Sam Laidlaw will step down as a Director of the Company. Sam was appointed to the Board in February 2017 and has served as Chair of our People & Remuneration Committee and as the Senior Independent Director. I would like to express my sincere thanks to Sam, on behalf of the Board, for his outstanding contribution to Rio Tinto. Ben Wyatt will succeed Sam as Chair of the People & Remuneration Committee and Sharon Thorne will become our Senior Independent Director. In the second half of 2025, Simon Henry will step down as a Director. Simon was appointed to the Board in April 2017 and has served as Chair of the Audit & Risk Committee since May 2019. We are grateful to Simon for his invaluable contribution to the Group. Sharon Thorne will succeed Simon as Chair of the Audit & Risk Committee. Kaisa Hietala will also step down as a Director at the conclusion of the Rio Tinto Limited AGM in May 2025. The recent growth in our Lithium business has increasingly created potential conflicts of interest with Kaisa’s non-executive directorship with Exxon Mobil. Out of an abundance of caution, Kaisa has offered to resolve this potential conflict by stepping down from the Rio Tinto Board. Kaisa has been a very welcome and valuable addition to the Board since her appointment in March 2023, and her guidance on energy transition and business transformation in particular have contributed significantly and insightfully to our discussions. While she will be greatly missed, we have accepted her decision to step down and wish Kaisa well for the future. 2025 Climate Action Plan This year we are seeking shareholder approval for our 2025 Climate Action Plan (2025 CAP). The plan sets out our continued strategy to provide the materials that are needed for the energy transition, retain our commitments to reduce emissions from our operations, and work with our partners to cut emissions through the value chain. The 2025 CAP is underpinned by a clear pathway to reduce Scope 1 and 2 emissions by 50% by 2030, and ultimately targets net zero operational emissions by 2050. It details how Rio Tinto will decarbonise its operations and value chain through partnerships, disciplined investment in projects, and by developing new technologies. These actions are putting us in a strong position today, and for a low-carbon future. Board recommendation The Board is unanimously of the opinion that Resolutions 1 to 23 (inclusive) proposed in this notice are in the best interests of shareholders and of Rio Tinto as a whole and recommends that you vote FOR these resolutions. However, Resolution 24 has not been proposed by the Board, but requisitioned by certain shareholders pursuant to section 338 of the UK Companies Act 2006. The resolution and their accompanying explanatory statement (which is set out in Appendix 1 on page 14), should be read together. The Board considers that Resolution 24 is against the best interests of shareholders and of Rio Tinto as a whole and recommends that you vote AGAINST this resolution for the reasons set out on pages 12-13 and in Appendix 2 on page 15. Voting and results 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, 1 April 2025 in line with the instructions on pages 19-20. 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 online, as described on page 18. The corresponding Rio Tinto Limited AGM will take place in Perth on Thursday, 1 May 2025. The result of the votes on Resolutions 1 to 19 (inclusive), which are also being proposed to the Rio Tinto Limited AGM, 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 20 to 24 (inclusive), which only apply to Rio Tinto plc, will be released as soon as possible after the Rio Tinto plc AGM. I look forward to welcoming you to the AGM and thank you for your continued support of Rio Tinto. Yours sincerely Dominic Barton Chair 19 February 2025 2 Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Resolutions 4-15 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 Sharon Thorne, who was appointed to the Board as an independent Non-Executive Director with effect from 1 July 2024 and is seeking election for the first time, and Sam Laidlaw and Kaisa Hietala, who will step down from the Board at the conclusion of the Rio Tinto Limited AGM on 1 May 2025 and therefore will not be seeking re-election, all other Directors will retire and offer themselves for re-election. Rio Tinto has satisfactorily undertaken checks into Sharon’s background and experience prior to her appointment. Sharon brings significant financial expertise to the Board and will succeed Simon Henry as Chair of the Audit & Risk Committee when Simon steps down from the Board later this year. 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 102-103 of the 2024 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.

Resolutions 16-17 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 2026 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 18 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. 9Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions 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 2024, contributions to Rio Tinto America PAC by 14 employees amounted to US$14,815, and Rio Tinto America PAC donated US$10,500 in political contributions in 2024. 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 2024 Annual Report. Words and expressions used in Resolution 18 that are defined in Part 14 of the UK Companies Act shall have the same meanings for the purposes of Resolution 18. Resolution 19 2025 Climate Action Plan Resolution 19 is a non-binding advisory vote in relation to Rio Tinto’s 2025 Climate Action Plan (2025 CAP). The 2025 CAP is set out in pages 41-75 of the 2024 Annual Report and is available at riotinto.com/annualreport. It sets out the company’s climate ambitions and strategy, emissions targets and the actions to achieve them. We will continue to publish our progress annually in line with reporting standards and to regularly engage with shareholders and other stakeholders on our climate commitments. Rio Tinto has a key role to play in the global transition to a low carbon economy. This includes producing the materials the world needs to decarbonise such as the copper, aluminium and iron ore increasingly required for electrification and transition of energy systems and by reducing our own, operational emissions, and helping our customers reduce theirs. Our first CAP was approved by shareholders at our 2022 AGMs with the support of 84.3% of the votes cast, and included a commitment to report on our progress annually and to update the CAP every 3 years. The 2025 CAP builds on our 2022 CAP by detailing our strategy to grow production of transition materials, retaining our commitments to reduce operational emissions and demonstrating that working together with our customers, suppliers and others will support the decarbonising of our value chains. In particular, the 2025 CAP includes: – How our Group Scenarios are utilised to identify climate risks and portfolio opportunities, and are applied to test the resilience of our strategy and business under a range of outcomes. – The carbon footprint of our operations and value chain, the medium and long-term decarbonisation targets for our Scope 1 and 2 emissions and how we are working with customers and suppliers on the emissions of our value chains. – The pathway and approach to reducing operational emissions including: 1) developing renewable electricity solutions at our Pacific Aluminium Operations and other assets, 2) transitioning from diesel usage by our mining operations’ mobile equipment, and 3) addressing hard-to-abate processing emissions in our smelting and refining facilities. – How we are integrating high – integrity nature-based solutions into our decarbonisation strategy and the limited use of offsets towards our 2030 decarbonisation targets. – Capital and other expenditure allocated to achieving our decarbonisation targets and the disciplined investment approach taken to determining allocation of this capital. – How we are working with communities and host countries to facilitate a transition that puts people at the centre while working to minimise impacts and optimise socio-economic opportunities. – Our approach to supporting policies which enable the decarbonisation of operational emissions, the production of metals and minerals required for the energy transition, and progress towards the goals of the Paris Agreement directly with host governments and indirectly via industry associations. – The strategies which are enhancing our physical resilience to a changing climate, and supporting the viability of our assets, people, and communities. – Details of the integration of decarbonisation progress into short- and long-term incentives, and how the Board engages on climate issues. The CAP is underpinned by a clear pathway to achieving 50% reductions in Scope 1 and 2 emissions by 2030 and ultimately targeting net zero operational emissions by 2050. The Board regularly reviews progress against our climate commitments is fully aligned with this action plan and believes it will deliver value for our shareholders, our customers and wider society positioning Rio Tinto strongly for the low carbon future. This advisory vote in no way removes the Board’s responsibility for the Group’s climate strategy, but rather offers shareholders the opportunity for a more informed dialogue on Rio Tinto’s climate ambition, in addition to other engagement opportunities. The Board recommends that shareholders vote in favour of the proposed 2025 CAP which retains ambitious emissions reduction targets and strengthens the company by positioning Rio Tinto to produce the materials in increasing demand from the energy transition and reducing our exposure to volatile fossil fuel prices and higher carbon penalty costs. The Board is ultimately responsible for determining our climate strategy, and this vote is non-binding. The Board will consider the outcome and discussions from the meeting in advancing the 2025 CAP. The Board and the management team are committed to ensuring that the CAP will guide the actions of all Group product groups, entities and functions. 10 Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions Resolution 20 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 £41,768,389 (representing 417,683,890 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 7 February 2025, 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 or other pre-emptive offer 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 2,907,902 treasury shares, which represents 0.23% 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 2026 (or, if earlier, at the close of business on 30 June 2026) 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 including the Investment Association’s Share Capital Management Guidelines, to manage the Group’s capital resources. Resolutions 21 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 £8,121,339 (representing 81,213,390 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 21 is passed, the authority will expire at the end of the AGM of the Company held in 2026 (or, if earlier, at the close of business on 30 June 2026) 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. The Board confirms that it intends to follow the shareholder protections contained in Part 2B of the Pre-Emption Group Principles. Resolution 22 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 22, 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 2025 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 2024, there were no capital management share purchase programmes. 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 2024 AGMs and expire on the date of the 2025 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 2026 (or, if earlier, at the close of business on 30 June 2026). The authority sought would permit the Company, Rio Tinto Limited and/or any of Rio Tinto Limited’s subsidiaries to purchase up to 125,305,168 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. 11Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions 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 2024 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 2024 financial statements, would increase the ratio of net debt to total capital by 0.7 percentage points, from 8.7% to approximately 9.4%. The total number of outstanding employee share awards at the Latest Practicable Date was 4,326,194, which represents 0.35% of the issued ordinary share capital, excluding the shares held in treasury at that date. If the Company were to buy back the maximum number of shares permitted pursuant to this resolution, then this number of awards would represent 0.38% 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 23 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 23. 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 2025 AGM on 1 May 2025. Resolution 23 Notice period for general meetings other than AGMs 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 24 seeks to renew this approval. The approval will be effective until the Company’s AGM in 2026, 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. Resolution 24 Shareholder requisitioned resolution Resolution 24 has not been proposed by the Board but has been requisitioned by certain shareholders pursuant to section 388 of the Companies Act. Their explanatory statement is set out in Appendix 1 on page 14, which the Company is required to circulate to shareholders pursuant to section 314 of the Companies Act. Statement by the Board The Board considers that Resolution 24 is against the best interests of shareholders and of Rio Tinto as a whole and unanimously recommends that you vote AGAINST Resolution 24. The reasons for this recommendation are summarised below and are set out in more detail in Appendix 2 on page 15. Rio Tinto periodically reviews the merits of retaining the DLC structure as part of evaluating options to maximise sustainable value for all Rio Tinto shareholders. A comprehensive review of the DLC structure by the full Board was completed in 2024. That review lasted several months and included substantial input and advice from external financial advisers (Goldman Sachs and J.P. Morgan) and legal advisers (Linklaters LLP and Allens). Detailed tax analysis was undertaken by professional services firm EY. The Board carefully considered the findings of the review and reached the unanimous conclusions summarised below. The DLC structure continues to be effective and provide benefits to Rio Tinto and its shareholders (i) The DLC structure provides access to significant depth of liquidity in demand for, and trading of, Rio Tinto shares. This is achieved through primary listings and premium index inclusion in two major capital markets and mining investment centres, with a pre-eminent position in the UK market. 12 Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Explanatory notes to the resolutions (ii) The DLC structure provides flexibility to raise capital, pursue strategic M&A and deliver shareholder returns. The DLC structure provides optionality for the Group to offer equity in either Rio Tinto plc or Rio Tinto Limited to raise capital or use as share consideration in acquisitions. The DLC structure fully supports the Group’s shareholder returns policy with Rio Tinto plc being one of the top five dividend payers in the FTSE-100. (iii) The DLC structure enables a more efficient utilisation of franking credits. Since the DLC structure was established, Rio Tinto Limited has always paid fully franked dividends to its shareholders and it is anticipated that Rio Tinto Limited will continue to do so in the longer term. Under a unified Rio Tinto, franking credits would need to be attached to all dividends paid, even though shareholders not tax-resident in Australia could not utilise them. It is anticipated that the Group would not be able to pay fully franked dividends in the longer term under a unified structure. A unification under Rio Tinto Limited would be value destructive for the Group (i) Unification is expected to result in tax costs in the mid-single digit billions of US dollars. This would reduce the Group’s net asset value per share. These tax costs were subject to detailed analysis by professional services firm EY. The nature and scope of these tax costs are specific to Rio Tinto, taking into account its structure, with significant operations outside Australia being held by Rio Tinto plc, and the tax positions across the large number of jurisdictions in which it operates. It is therefore misleading to compare the costs of unification for Rio Tinto to other companies. (ii) Unification is not expected to result in a unified Rio Tinto trading at or above the Rio Tinto Limited share price. There is unlikely to be sufficient incremental demand from Australian tax-resident shareholders to absorb the very significant number of new Rio Tinto Limited shares that would be issued on unification and therefore to support a higher unified Rio Tinto share price. As such, it is more likely that a re-rated unified Rio Tinto share price would trend towards the weighted average of the Rio Tinto plc and Rio Tinto Limited share prices. The Board firmly rejects Palliser’s claim that the DLC structure has resulted in value destruction of c.US$50 billion The Board believes that the assertions made by Palliser Capital Master Fund Ltd and its affiliates (together Palliser) are unfounded and misleading. They are based on flawed and highly selective assumptions. As set out in further detail in Appendix 2, Palliser attributes c.US$35.6 billion of this value to the “inability to issue stock for M&A” based on hypothetical assumptions for historical acquisitions by Rio Tinto. Palliser has failed to consider the matrix of factors that would have been considered by Rio Tinto at the time of each acquisition including, but not limited to, Rio Tinto’s capital allocation framework, the expectation of shareholder returns under different funding sources, and each acquisition counterparty’s willingness to accept Rio Tinto shares. Palliser attributes c.US$14.7 billion of value to franking credits that would have been utilised without the DLC in place. This is based on an unreasonable assumption that there would have been sufficient incremental demand for unified Rio Tinto shares from Australian tax-residents to utilise these franking credits and does not account for the resulting depletion of franking credits to facilitate fully-franked dividends in the longer term. The Board firmly rejects the notion that the DLC structure has resulted in value destruction of c.US$50 billion, and reiterates its strong focus on sustainable shareholder value creation and effective capital management. Resolution 24 is therefore against the best interests of shareholders and Rio Tinto as a whole Given the comprehensive review conducted in 2024 and the conclusive findings from that review in support of retaining the DLC structure, the Board unanimously believes that the proposal as set out in Resolution 24 is highly duplicative and unnecessary. There is no basis for expecting that an additional review including an independent expert report would lead to a different conclusion. In addition, there would be limited information that could be reasonably disclosed publicly given the confidential and highly commercially sensitive nature of the information, including detailed analysis of tax costs and forecast financial information. Publication of the full findings would be materially prejudicial to shareholders’ interests. Your Directors therefore unanimously recommend that you vote AGAINST Resolution 24, as the Directors intend to do so in respect of their own beneficial holdings. Appendix 2 on page 15 contains further details setting out the reasons for the Board’s recommendation. Further information in relation to Resolution 24 may be published on the Rio Tinto website at riotinto.com/agm. 13Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

“Our resolution seeks an independent, comprehensive and transparent review on whether Rio Tinto’s dual listed companies (“DLC”) structure should be unified into a single Australian-domiciled holding company. Management’s decision to retain the DLC structure conflicts starkly with the global opinion that the archaic structure lacks durability and that the interests of shareholders are best served though a conventional company structure. With such an extreme difference of opinion on a topic of such critical importance, the logical next step must be to test the anomalous conclusions of management’s internal review through our requested review. There is so much at stake for shareholders – indeed, Palliser Capital (UK) Limited and its affiliates (together, “Palliser”) believe that unification has the potential to unlock US$28 billion (27%) of upside in the near term for the shareholders of Rio Tinto Plc and further upside for the combined group over the medium term: https://unifyrio.com. Almost every other company with a DLC structure has already successfully unified it. Their directors – a cumulative >136 of them – concluded that the outdated structure was no longer working because of its serious inefficiencies. In all but one case, both ISS and Glass Lewis found their reasons for unification so persuasive that they recommended shareholders vote in favour of it.1 And that is exactly what shareholders did – by an overwhelming c.98%, on average. Indeed, the DLC-unwind of Rio Tinto’s closest peer, BHP, was recommended by each of its directors and approved by 97% of the shareholders who voted, many of whom are also shareholders in Rio Tinto. Even though BHP’s Australian line traded at a premium of 15%-20% to its UK line at the time, the shareholders in the Australian entity (98%) still believed that they would be better off under a single holding company rather than in two asymmetrical parts. BHP’s independent expert, Grant Samuel, set out the compelling rationale for why its shareholders were better off in a unified structure, much of which would evidently apply to Rio Tinto: https://www.bhp.com/-/media/documents/investors/ shareholderinformation/2021/unification/3circular.pdf. Time and time again, similar shortcomings of the DLC structure have been identified by directors and experts alike, as the reason for an unwind: (1) an inefficient capital structure; (2) impediment on capital allocation options; (3) a sub-optimal corporate governance regime; and (4) in the case of the UK/Australian DLCs, under-utilisation of franking credits. Palliser have assessed the financial impact of some of these deficiencies on Rio Tinto’s shareholders over the 30 year period since Rio Tinto incepted its DLC structure – which has seen 6 chairmen, 7 CEOs, 5 CFOs, 71 directors, 60 members of the executive committee and multiple market cycles come and go. Through independent expert analysis, they estimate that shareholders would have been c.US$50 billion better off so far, without the legacy structure: 1. Since establishment in 2004, Glass Lewis recommended for unification, save for Thomson Reuters’ because the post-unification legal requirements on executive pay were not as stringent as those under the DLC structure. 2. Based on Rio Tinto’s reported taxes for 2023. 3. Excludes tender offers for minority shareholders in existing listed subsidiaries which included a cash or scrip alternative. 4. Rio Tinto implied total shareholder return based on weighting of total shares outstanding across Plc and Limited. 5. All figures are calculated as at 29 November 2024. – Rio Tinto’s inability to offer an industry standard mix of cash and equity for its acquisitions has cost shareholders c.US$35.6 billion in additional book value; and – in a failure to achieve the DLC’s own stated objective, an estimated c.US$14.7 billion less franking credits have been utilised under the DLC structure compared to if Rio Tinto had been set up as an Australian holding company in 1995. Today, the outdated structure is alone responsible for a glaring US$24 billion valuation gap between the supposedly “equivalent” shares of Rio Tinto Plc and Rio Tinto Limited. With such a persuasive rationale for unification, management’s conclusion to maintain a corporate structure that every other large cap DLC has moved on from makes little sense: – Management asserts that unification would cost “mid-single digit billions of dollars”: Palliser estimates that the one-off transaction costs would total c.US$400 million. Furthermore, their independent tax analysis indicates that management’s figure consists primarily of an estimated c.US$140 million of additional annual tax expenses that would be payable by a unified Rio Tinto going forward, representing a <2% increase in annual tax paid by Rio Tinto2 and <0.6% of the group’s annual EBITDA. – Management claims that the DLC structure is no impediment to stock-based M&A: In reality, Rio Tinto has funded 100% of its acquisitions entirely with cash over the last 3 decades.3 This position is not only unsustainable but could seriously hinder Rio Tinto’s ability to diversify its portfolio at a time when key mining industry players are racing to secure scarce supply of metals critical to the energy transition. – Management predicts that the share price of a unified Rio Tinto would trade “down in a double-digit percent”: This did not happen in the highly comparable case of BHP, so why would it happen to Rio Tinto? Indeed, BHP’s total shareholder return has consistently outperformed Rio Tinto’s since announcement and completion of its own unification.4 – Management asserts that shareholder approval for unification would “be impossible”: Past precedents highlight the unequivocal preference of former DLC shareholders for a simplified corporate structure. With an average DLC shelf life of 9 years (excluding the Shell and Unilever anomalies), their shareholders did not have to wait so long before they were afforded the choice to unify. Management’s reasons to retain the status quo do not stand up against the weight of global evidence in favour of unification. With Palliser demonstrating the severe value-destruction caused by the DLC structure as well as the value-maximising opportunity unlocked through unification, it is only appropriate that Rio Tinto now conducts the more vigorous review we are seeking. Our request is not onerous but it is essential to properly assure shareholders that their ownership structure is truly suitable for the second largest mining company in the world.5” Appendix 1 – Statement provided by Palliser and other requisitioning shareholders in support of Resolution 24 14 Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Appendix 2 – Statement by the Board in response to Resolution 24 The Board considers that Resolution 24 is against the best interests of shareholders and of Rio Tinto as a whole and unanimously recommends that you vote AGAINST Resolution 24. A comprehensive review of the DLC structure by the full Board was completed in 2024 The Board regularly evaluates options to maximise sustainable value for all Rio Tinto shareholders. In this capacity, the Board periodically reviews the merits of retaining the DLC structure, most recently with a comprehensive review undertaken in 2024. The review was conducted over several months in 2024 and included substantial input and advice from external financial advisers (Goldman Sachs and J.P. Morgan) and legal advisers (Linklaters LLP and Allens). Detailed tax analysis was undertaken by professional services firm EY. The review considered alternative scenarios and took account of the specific characteristics and circumstances of Rio Tinto’s DLC structure, recognising that the reasons why other companies have unified their DLC structure, and the costs and benefits associated with doing so, do not apply to Rio Tinto given the materially different facts and circumstances of Rio Tinto’s own DLC structure. Specific factors considered include: (i) the geographic locations of the Group’s businesses with significant assets outside Australia held under Rio Tinto plc; (ii) the distribution of the Group’s shareholders which is heavily weighted towards Rio Tinto plc; and (iii) that a unification under Rio Tinto Limited would require the approval by special resolution of shareholders of each of Rio Tinto plc and Rio Tinto Limited. The findings were carefully considered by the full Board, including independent non-executive directors, at a specially convened board meeting in June 2024. The conclusions and recommendations of the review were critically and comprehensively tested and challenged by the Board, the majority of whom are independent directors appointed in the last three years. The Board concluded unanimously that unification under Rio Tinto Limited (or any other approach to unification of the DLC structure) is against the best interests of Rio Tinto, and of Rio Tinto plc’s and Rio Tinto Limited’s shareholders as a whole, and that the DLC structure should be retained. Rio Tinto has also engaged with Palliser at six meetings in 2024 and reviewed the analysis produced by Palliser. The Board has unanimously reaffirmed its conclusion in light of the assertions made by Palliser. An additional review as proposed by Resolution 24 is highly duplicative and proposed disclosure would be materially prejudicial to shareholders’ interests Given the rigorous process undertaken and the findings of the comprehensive review in 2024, the Board firmly believes that a further review as proposed by Resolution 24 would be highly duplicative of the comprehensive review already undertaken and is therefore unnecessary. It is the Board’s view that an additional review including an independent expert report would lead to the same conclusion. In addition, the findings of a further review would contain confidential and highly commercially sensitive information, including detailed analysis of tax costs and forecast financial information. If published, such analysis and information would be materially prejudicial to shareholders’ interests and could have unintended and adverse consequences for Rio Tinto. The Board therefore believes that the information which could reasonably be disclosed, as proposed by Resolution 24, would be limited. The Board further considers the attendance by a shareholder representative at a committee, as proposed by Resolution 24, to be inappropriate. The shareholder may not be representative of the views of the Group’s wider investment community. They would also have access to confidential and highly commercially sensitive information that could not be made publicly available to other shareholders. Consistent with best practice, Rio Tinto’s established programmes for shareholder engagement already facilitate feedback and open dialogue to maximise the long-term value of the Group. Why the Board unanimously supports retaining the DLC structure 1. The DLC structure continues to be effective and provides benefits to Rio Tinto and its shareholders (i) The DLC structure provides Rio Tinto with access to global capital markets. The DLC structure provides access to significant depth of liquidity in demand for, and trading of, Rio Tinto shares. This is achieved through primary listings and premium index inclusion in two major capital markets and mining investment centres. Rio Tinto plc has a pre-eminent position in the UK market as the default investment in the mining sector and one of the ten largest companies in the FTSE-100 index. (ii) The DLC structure provides flexibility to raise capital, pursue strategic M&A and deliver shareholder returns. – The DLC structure provides optionality for raising capital and executing strategic M&A. The DLC structure provides the ability to offer equity in either Rio Tinto plc or Rio Tinto Limited to raise capital or use as share consideration in acquisitions. The choice of cash or equity, in either Rio Tinto plc or Rio Tinto Limited (or both), to fund acquisitions is a function of a broad range of factors including, amongst others, balance sheet capacity, impact on earnings per share and target shareholders’ preferences. Since the formation of the DLC structure, Rio Tinto has undertaken strategic M&A using stock and/or cash. In each case Rio Tinto carefully evaluates all acquisition funding options to deliver the optimal outcome for shareholders. – The DLC structure fully supports the Group’s shareholder returns policy. Rio Tinto intends to continue to distribute significant amounts of cash to shareholders, which the Board acknowledges is at the core of the Group’s investment proposition. Since implementing its shareholder returns policy in 2016, the Group has consistently delivered cash returns to shareholders at the upper end of the 40% to 60% range, in line with or above key peers. Rio Tinto plc is one of the top five dividend payers in the FTSE-100. The Board expects total cash returns to shareholders over the longer term to be in a range of 40% to 60% of underlying earnings in aggregate through the cycle. 15Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Appendix 2 – Statement by the Board in response to Resolution 24 (iii) The DLC structure enables a more efficient utilisation of franking credits.6 Unification under Rio Tinto Limited would be expected to result in the wastage of franking credits and the inability to pay fully franked dividends over time. – Rio Tinto’s current use of franking credits does not limit its ability to pay fully franked dividends to Rio Tinto Limited shareholders. While the Group uses franking credits when Rio Tinto Limited pays a dividend internally within the Group to Rio Tinto plc, this has never and is not expected to impact Rio Tinto Limited’s ability to pay fully franked dividends to its public shareholders. Since the formation of the DLC structure in 1995, Rio Tinto Limited has always paid fully franked dividends to its shareholders and it is anticipated that Rio Tinto Limited will continue to pay fully franked dividends in the longer term under the DLC structure. Given that a meaningful portion of the Group’s earnings growth is currently from outside Australia, a feature that is expected to increase over time, the need for Rio Tinto Limited to pay a dividend to Rio Tinto plc internally within the Group is expected to decrease to nil over time. – A unified Rio Tinto share price under Rio Tinto Limited may be adversely affected by insufficient availability of franking credits in the longer term. Under a unified Rio Tinto, franking credits would need to be attached to all dividends paid, even though shareholders not tax-resident in Australia could not utilise them. It is anticipated that the Group would not be able to pay fully franked dividends in the longer term under a unified structure. Under the current DLC structure, franking credits are only attached to dividends paid by Rio Tinto Limited, effectively preserving them for the shareholders that can utilise them. 2. Unification under Rio Tinto Limited would be value destructive for the Group (i) Unification of the DLC structure would be expected to result in tax costs in the mid-single digit billions of US dollars. Contrary to Palliser’s claims, unification is not a “low cost” decision from a tax perspective. The expected tax costs are specific to Rio Tinto and the analysis is unique to the Group’s structure, its tax positions across the large number of jurisdictions in which it operates and the fact that almost all of the Group’s operational assets outside Australia are held under Rio Tinto plc. It is therefore not meaningful to compare the costs of unification for Rio Tinto to other companies. As part of the review conducted in 2024, detailed tax analysis was undertaken by professional services firm EY. The results of the tax analysis confirmed that Palliser has significantly under-stated the expected tax costs. The Board believes it is neither appropriate nor customary to publish detailed tax analyses as they contain confidential and highly commercially sensitive information which would be materially prejudicial to the interests of Rio Tinto and its shareholders if made public. 6. Franking credits are tax credits available to shareholders which arise from Australian corporate tax paid on profits generated by Rio Tinto Limited’s Australian assets. These franking credits can be used solely by Rio Tinto Limited shareholders who are tax-resident in Australia to offset tax liabilities on their dividends. Franking credits provide an exemption from Australian dividend withholding tax if payable to shareholders who are not tax-residents in Australia but cannot otherwise be utilised by those shareholders. Franking credits are therefore effectively wasted in the hands of a non-Australian resident shareholder. (ii) Unification is not expected to result in a unified Rio Tinto trading at or above the Rio Tinto Limited share price. The difference between Rio Tinto plc’s and Rio Tinto Limited’s share price is influenced by jurisdiction-specific factors. Rio Tinto Limited’s shares currently trade at a higher price than Rio Tinto plc’s shares, primarily because of the additional value that is ascribed by Australian investors to franking credits, as well as broader market sentiment, equity market flows, index composition and other factors in Australia and the UK. Based on extensive analysis, the Board believes that following a unification, it is highly unlikely that the Rio Tinto Limited share price would be maintained at pre-unification levels, and that it is more likely that the share price would trend towards the weighted average of the Rio Tinto plc and Rio Tinto Limited share prices. This is because Rio Tinto plc currently represents 77% of the issued share capital of the DLC structure, and Rio Tinto Limited currently represents 23% of the issued share capital of the DLC structure. A unification under Rio Tinto Limited would therefore entail 77% of Rio Tinto’s issued share capital in the form of Rio Tinto plc shares being exchanged for Rio Tinto Limited shares. The Board believes that in order for the unified Rio Tinto share price to reflect the higher Rio Tinto Limited share price, incremental demand estimated at tens of billions of US dollars would need to emerge post-unification from Australian tax-resident shareholders who benefit from franking credits to absorb the very significant number of new Rio Tinto Limited shares that would be issued on unification. The Board does not believe it is reasonable to assume this would eventuate and it considers Palliser’s claim that the share price of the unified Rio Tinto would instead trade up to, and ultimately surpass, the current price of Rio Tinto Limited to be flawed and unsubstantiated. The Board firmly rejects Palliser’s claims that the DLC structure has resulted in value destruction of c.US$50 billion The Board firmly rejects Palliser’s claim of c.US$50 billion of lost value over the past 30 years, of which Palliser states c.US$35.6 billion is attributable to structural impediments caused by the DLC structure. The Board believes that Palliser has failed to properly assess the implications of the DLC structure for shareholder value and its assertions of an alleged c.US$50 billion value loss are unfounded, misleading and based on highly selective assumptions: (i) Palliser argues that the “inability to issue stock for M&A” under Rio Tinto’s existing DLC structure has cost shareholders c.US$35.6 billion in value (defined as a reduction in the Group’s book value, attributing a hypothetical proportion of share consideration for Rio Tinto’s historic M&A transactions). Palliser’s analysis is based on retrospectively applying an “industry average of 68:32 stock to cash” to fund most of Rio Tinto’s past acquisitions. Palliser’s hypothetical assumptions fail to consider the matrix of factors that would have been considered at the time of each acquisition, including Rio Tinto’s capital allocation framework, the expectation of shareholder returns under different funding scenarios, and each acquisition counterparty’s willingness to accept Rio Tinto shares. 16 Rio Tinto plc 2025 Notice of annual general meeting | riotinto.com

Appendix 2 – Statement by the Board in response to Resolution 24 (ii) Palliser argues that, since the formation of the DLC structure in 1995, c.US$14.7 billion of additional franking credits would have been utilised without the DLC structure in place. Palliser’s analysis is based on an unreasonable assumption that there would have been sufficient incremental demand for unified Rio Tinto shares from Australian tax-residents, which as noted at paragraph 2(ii) above, the Board does not believe is reasonable. Palliser does not account for the Board’s view that the Group would not be able to pay fully franked dividends in the longer term under a unified structure (as set out at paragraph 1(iii) above). Contrary to Palliser’s claims of value destruction, Rio Tinto’s continuous focus on sustainable shareholder value creation and effective capital management has been core to the financial success of the Group. This is evidenced by factors such as: (i) Rio Tinto plc outperforming the FTSE 100 index; and (ii) Rio Tinto Limited outperforming the ASX 200 index, in each case over the “30 year period since the inception of this DLC structure”, as referenced by Palliser – both in terms of share price performance as well as on a total shareholder return basis.7 In light of all of the above, the Directors unanimously believe Resolution 24 is against the best interests of shareholders and of Rio Tinto as a whole. Your Directors therefore unanimously recommend that you vote AGAINST Resolution 24, as the Directors intend to do so in respect of their own beneficial holdings. Further information about Resolution 24 may be published on the Rio Tinto website at riotinto.com/agm. 7.

Further information about the meeting 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.
