By accessing/attending this presentation you acknowledge that you have read and understood the following statements. Production Targets The 500kpta copper and 350kozpa gold target (stated as recoverable metal) for the Oyu Tolgoi underground and open pit mines for the years 2028 to 2036 referenced in slides 14 and 21 is underpinned 13% by Proved Ore Reserves and 87% by Probable Ore Reserves. This production target has been scheduled from mine designs based on the Oyu Tolgoi Feasibility Study 2020 (OTFS20), which are not materially different to current mine designs, by Competent Persons in accordance with the requirements of the Australasian Code for Reporting of Exploration Results, Minerals Resources and Ore Reserves, 2012 Edition (the JORC code). The production profiles for the Oyu Tolgoi underground and open pit mines shown in slide 43 are underpinned 41% by Proved Ore Reserves and 59% by Probable Ore Reserves for 2023 to 2027, and 10% by Proved Ore Reserves and 90% by Probable Ore Reserves for 2028 to 2036. The life of mine production profile shown in slide 43 is underpinned 22% by Proved Ore Reserves and 78% by Probable Ore Reserves for 2023 to 2051. The financial forecasts shown in slide 44 are based on production targets which are underpinned 43% by Proved Ore Reserves and 57% by Probable Ore Reserves for 2023 to 2025, 26% by Proved Ore Reserves and 74% by Probable Ore Reserves for 2026 to 2029, and 9% by Proved Ore Reserves and 91% by Probable Ore Reserves for 2030 to 2033. These production targets are stated as recovered metal and have been scheduled from current mine designs for the Oyu Tolgoi underground and open pit mines by Competent Persons in accordance with the requirements of the Australasian Code for Reporting of Exploration Results, Minerals Resources and Ore Reserves, 2012 Edition (The JORC code). Forward-looking statements This presentation includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts included in this report, including, without limitation, those regarding Rio Tinto’s financial position, business strategy, plans and objectives of management for future operations (including development plans and objectives relating to Rio Tinto’s products, production forecasts and reserve and resource positions), are forward-looking statements. The words “intend”, “aim”, “project”, “anticipate”, “estimate”, “plan”, “believes”, “expects”, “may”, “should”, “will”, “target”, “set to” or similar expressions, commonly identify such forward-looking statements. Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Rio Tinto, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements, particularly in light of the current economic climate and the significant volatility, uncertainty and disruption arising in connection with the Ukraine conflict. Such forward-looking statements are based on numerous assumptions regarding Rio Tinto’s present and future business strategies and the environment in which Rio Tinto will operate in the future. Among the important factors that could cause Rio Tinto’s actual results, performance or achievements to differ materially from those in the forward-looking statements include, but are not limited to: an inability to live up to Rio Tinto’s values and any resultant damage to its reputation; the impacts of geopolitics on trade and investment; the impacts of climate change and the transition to a low-carbon future; an inability to successfully execute and/or realise value from acquisitions and divestments; the level of new ore resources, including the results of exploration programmes and/or acquisitions; disruption to strategic partnerships that play a material role in delivering growth, production, cash or market positioning; damage to Rio Tinto’s relationships with communities and governments; an inability to attract and retain requisite skilled people; declines in commodity prices and adverse exchange rate movements; an inability to raise sufficient funds for capital investment; inadequate estimates of ore resources and reserves; delays or overruns of large and complex projects; changes in tax regulation; safety incidents or major hazard events; cyber breaches; physical impacts from climate change; the impacts of water scarcity; natural disasters; an inability to successfully manage the closure, reclamation and rehabilitation of sites; the impacts of civil unrest; the impacts of the Ukraine conflict; breaches of Rio Tinto’s policies, standard and procedures, laws or regulations; trade tensions between the world’s major economies; increasing societal and investor expectations, in particular with regard to environmental, social and governance considerations; the impacts of technological advancements; and such other risks identified in Rio Tinto’s most recent Annual Report and accounts in Australia and the United Kingdom and the most recent Annual Report on Form 20-F filed with the United States Securities and Exchange Commission (the “SEC”) or Form 6-Ks furnished to, or filed with, the SEC. Forward-looking statements should, therefore, be construed in light of such risk factors and undue reliance should not be placed on forward- looking statements. These forward-looking statements speak only as of the date of this report. Rio Tinto expressly disclaims any obligation or undertaking (except as required by applicable law, the UK Listing Rules, the Disclosure Guidance and Transparency Rules of the Financial Conduct Authority and the Listing Rules of the Australian Securities Exchange) to release publicly any updates or revisions to any forward-looking statement contained herein to reflect any change in Rio Tinto’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based.

China imported 0.4Mt of primary aluminium in Jan-May 2023, averting a decline in inventories to unsustainably low levels • Price rebound from H2 2022, although still lower than last year as global macro uncertainty dampens sentiment • China demand growth positive despite downturn in construction, driven by electric vehicles and renewable sectors. Demand in US and EU was resilient in Q1 but has softened thereafter • Mine supply disruptions in Q1 limited material availability; Chile’s production YTD remains weak, partially offset by higher production from Peru • Inventories have fallen sharply after China’s seasonal build-up in Q1 (down 50% YoY in June) • TiO2 feedstock prices relatively stable through H1 despite deteriorating market conditions further downstream • Demand for TiO2 products has continued to be impacted by weakening macro environment over the first half with construction indicators down across major TiO2 consuming regions • Sales volume declines for pigment producers and paint manufacturers in North America and Europe reported in Q1 0 150 300 450 600 750 900 1,000 1,500 2,000 2,500 3,000 3,500 4,000 Jan-20 Jul-20 Jan-21 Jul-21 Jan-22 Jul-22 Jan-23 Jul-23 LME Aluminium ($/t) HY Average MWP (RHS) 200 250 300 350 400 450 500 Jan-20 Jul-20 Jan-21 Jul-21 Jan-22 Jul-22 Jan-23 Jul-23 Price (c/lb) HY Average 700 800 900 1,000 1,100 Jan-20 Jul-20 Jan-21 Jul-21 Jan-22 Jul-22 Jan-23 Jul-23 CP Slag ($/t) HY average
