Notice to ASX Rio Tinto Limited AGM – Address by the Chair 04 May 2023 Dominic Barton, Chair Rio Tinto Limited Annual General Meeting 2023, Perth **Check against delivery** Good morning to everyone here in Perth, and to those of you joining virtually. It’s great to be back in Western Australia again. As Chair of Rio Tinto, it’s my pleasure to welcome you to our 2023 Annual General Meeting. First, I would like to acknowledge the Whadjuk people of the Noongar Nation on whose Traditional Lands I am speaking from today. And I pay my respects to all Traditional Owners and Indigenous people that host our operations around the world. It also gives me great pleasure to introduce Robyn Collard and Tryse Rioli. Robyn is a Noongar woman from the Whadjuk and Ballardong groups, and she is joined by her Grandson, a Noongar, Tiwi and Larrakia man. [Welcome to Country] Thank you Robyn for your welcoming words, and Tryse for your wonderful didgeridoo playing, and to both of you for opening our AGM. I am delighted to introduce my fellow members of the Rio Tinto Board: • Simon McKeon, Senior Independent Director of Rio Tinto Limited • Kaisa Hietala • Peter Cunningham, our Chief Financial Officer • Jakob Stausholm, our Chief Executive Officer • Tim Paine, our Australian Company Secretary • Sam Laidlaw, Senior Independent Director of Rio Tinto plc and Chair of our People & Remuneration Committee • Jennifer Nason • Simon Henry, Chair of our Audit & Risk Committee • Ngaire Woods • and Ben Wyatt Unfortunately, Megan Clark, Chair of our Sustainability Committee, is unwell and unable to be here with us today. We also have with us Trevor Hart, our external auditor from KPMG. We have seen further changes to the Board over the past year, with the departure of my predecessor Simon Thompson, and Hinda Gharbi. I would like to thank them both for their significant contribution and Simon in particular for his leadership as Chair of Rio and the welcome he gave me. When I became Chair, I committed to evaluate the mix of skills and experience that we would need for the next strategic phase for Rio. Exhibit 99.1

Notice to ASX 2 / 6 We concluded that we needed to refresh our composition, with a particular focus on strengthening our mining, operations and projects experience, as well as adding capabilities in renewable energy, energy transition and sustainability. We also felt we should deepen the expertise in Culture and on our Audit & Risk Committee. I am delighted that we have made significant progress in strengthening the Board with the appointment of Kaisa Hietala. Also, Susan Lloyd-Hurwitz and Dean Dalla Valle, two experienced Australian business leaders, will be joining us from 1 June. Kaisa brings a deep understanding of the resources industry, sustainability and renewables, as well as broad commercial capability. These skills will be invaluable as we work to ensure Rio Tinto thrives in a decarbonising world. Kaisa, perhaps I could hand over to you to say a few words. [Kaisa Hietala’s Remarks] Thank you Kaisa. When Dean and Susan join us on 1 June, they will further strengthen the Board in key areas, and I am greatly looking forward to working with them both. Dean is highly regarded across the mining industry for his operational and technical acumen, with a clear focus on safety. His vast experience of developing complex mining projects and of operating across various commodities on multiple continents will be invaluable. Susan is highly respected for her transformational leadership, and at Mirvac she established a strong culture that was purpose driven, commercial, inclusive and innovative. This experience will be particularly important for Rio Tinto as we continue our own journey of cultural transformation. Sue and Dean will of course stand for election at our annual general meetings next year. It is a privilege to be here today. AGMs play a key role in fostering dialogue and in building a shared understanding of the context in which we operate – they are opportunities for us as your Board to listen and learn from you, our shareholders, so that we can be better. And in order to make today’s proceedings as efficient as possible, I will now declare that voting on all resolutions is open. As usual, resolutions will be decided by poll. Let me reflect briefly on where Rio Tinto now stands as a company. Jakob and his Executive team have led the Group out of a challenging period, with the foundations now being laid for us to become the global mining company of choice. 2022 saw us deliver another set of strong financial results. We stabilised our operational performance in the second half of the year and have carried strong momentum into 2023. As a result, we have declared total dividends of US$8 billion for 2022 to you, our shareholders. This is in line with our policy and represents the second-largest ordinary dividend in our 150-year history. And the Group’s direct economic contribution to the countries where we operate, including payments to our employees, our suppliers, governments and our shareholders, amounted to $58.3 billion in 2022. We paid $10.8 billion in taxes and royalties globally. Alongside these important positives, of course, a lot remains to be done.

Notice to ASX 3 / 6 We must continue to focus on our four objectives: to become best operator, to strive for impeccable ESG credentials, to excel in development aligning our growth to what the world needs – and finally, to deepen our social licence. Building trust with our key stakeholders and strengthening our social licence was also a key focus in 2022. While it’s for others to judge our progress, I am proud of some recent achievements, in particular agreements reached with Indigenous peoples. In the months and years ahead, we must continue to focus on embedding the important culture change that is such a critical enabler for achieving our strategic objectives and to creating the future organisation that we all wish to see. Today, Rio Tinto is arguably more relevant and aligned with societal aspirations than we have ever been. This industry has traditionally been about meeting the demand created by ongoing urbanisation and economic growth, which we will continue to see. But the energy transition and drive to net zero, coupled with a renewed focus on security of supply, provides a further opportunity for Rio Tinto. According to the International Energy Agency, if the world is to meet the Paris climate goals, we will need: • 700 million tonnes of copper in the next 20 years (that is the same amount as we have produced since we existed). • The world’s installed wind power capacity must reach over 6000 gigawatts – approximately eight times the current level, and we need to do this by 2050. To put this into perspective, one wind turbine of three megawatts requires: 300 tonnes of steel; five tonnes of copper; three tonnes of aluminium; and two tonnes of rare earths. And electric vehicles and battery storage will raise lithium demand more than forty times by 2040; cobalt and nickel could increase over twenty times over the same period. So, we have a critical role to play in enabling the energy transition, supplying essential minerals, including copper, lithium, high-grade iron ore and aluminium, all of which are vital for the transition to a low carbon economy. However, within our new purpose: finding better ways to provide the materials the world needs, there also lies a fundamental tension. Meeting the needs of both the energy transition and continued global growth raises environmental and societal dilemmas. As a business and as a society, we need to acknowledge and balance these dilemmas in our decision-making as they involve some difficult trade-offs. And we need the help of our stakeholders in solving these. The big question to work through together is: how do we fulfil our role in the energy transition in a way that is socially and environmentally responsible, and yet sufficiently commercial, to attract the investment required? What I can say is that in meetings I have conducted with investors, governments, community leaders and other stakeholders since joining, there is an ever-increasing acknowledgment that mining is viewed as a critical industry in reliably and securely supplying the materials that the world needs for the energy transition. So, the industry is at an inflection point – we can be a catalyst of the green economy and potentially of transformative social impacts as we get to the unexplored corners of the world through mining, processing and recycling. We have key parts of government and society pushing us to develop and expand mining projects, but at the same time we have some stakeholders pushing back on any mining development.

Notice to ASX 4 / 6 So, we must continue our efforts to gain and strengthen the trust of our key stakeholders. Otherwise, we, as a society, will fall short on our ambitious climate goals. And with that trust comes both responsibilities and obligations. We face new expectations that require a more open, transparent approach to the development and governance of natural resources. We must address our own carbon footprint. We must partner to develop products and technologies that help our customers decarbonise. We are collaborating with universities, governments, companies and start-ups to build an industry-leading Technology and R&D organisation that can accelerate technology deployment, particularly in materials science. And we have already delivered some breakthroughs, such as scandium and tellurium production at Sorel and Kennecott, respectively. Alongside supplying transition materials, we are aiming to reduce our own emissions by 50% in 2030 and to reach net zero by 2050. We have ambitious short- and long-term targets. Without a doubt, there is considerable work ahead for us. But I believe that we are up for the challenge. Everything we aspire to achieve will be enabled by our people feeling empowered, respected, and inspired. One of my priorities as Chair is to ensure that we create a culture where everyone can be at their best. Continuous improvement has been part of Rio Tinto’s ways of working for years, and we are applying this principle to our culture. I commend Jakob and his team for the care and courage shown in commissioning and openly sharing the external review of the company’s workplace culture by Elizabeth Broderick at the beginning of 2022. Since then, a great deal has been done to make positive change. The Board and I fully support the implementation of the 26 recommendations made in the Everyday Respect Report, which we are delivering on and monitoring closely. And as a Board, we want to lead by example in embedding these cultural changes. We have expanded our new People & Remuneration Committee’s scope to include an ongoing focus on people and culture. In 2023, the global environment has certainly become more complex. We will need to maintain a keen eye on both near-term opportunities and risks, while also being able to capture strategic opportunities for the longer term. It is certainly an exciting time to be at Rio because we believe that we can add value in this complex global operating environment. There is again a sense that the company has reached an inflection point, with strong momentum in the business. And as we turn 150, I am confident we have all of the right ingredients in place – great people, world-class assets, emerging technologies and new partnerships. I am grateful to our many thousands of Rio Tinto employees, contractors and partners around the world who delivered for the company and its shareholders during the year. It’s because of you that our future looks bright. Let me finish with a thank you to my colleagues, especially Jakob and Peter, and also fellow Board members, for their hard work, commitment and dedication to Rio Tinto over the past year. In particular, I have enjoyed getting to know them, and appreciate their insights, advice and support as I have settled into my role as Chair of this great company.

Notice to ASX 5 / 6 I will now ask Jakob, our Chief Executive, to give us an update on the business. Thank you. [Jakob Stausholm’s speech] Thank you, Jakob. We will now move to the formal business of the meeting. The notice of meeting, containing the text of each resolution to be put to this meeting, was published on our website and made available to shareholders on 8 March. I will take the notice, as read. Resolutions 1 to 18 will be dealt with under the joint electorate procedure. Rio Tinto plc shareholders have cast their votes on these resolutions at the corresponding meeting in London, on 6 April. Resolution 19 will be voted on by Rio Tinto Limited shareholders only. Your directors are unanimously of the opinion that all the resolutions proposed in this notice are in the best interests of shareholders and of Rio Tinto as a whole. Accordingly, we recommend that you vote in favour of all the resolutions. I would now like to invite questions from shareholders on any matters relevant to the business of the meeting before we move on to voting on the resolutions themselves. Only shareholders or their representatives or proxyholders are entitled to ask questions. [Q&A session] Before I formally close the meeting, I want to extend my sincere thanks to Megan Clark who unfortunately is unable to be here today because she is unwell. Megan is leaving the Board after nine years of fantastic leadership and we are going to miss her. She has been a voice of wisdom and experience that the Board and I have deeply appreciated. Thank you, Megan. That brings us to the end of the meeting. On behalf of the Board, I would like to thank all of you for your participation and continued support. I hope that you will join my fellow directors and members of the executive team for some refreshments in the Foyer. I now declare the meeting closed.

Notice to ASX Rio Tinto Limited AGM – Address by the Chief Executive 04 May 2023 Jakob Stausholm, Chief Executive Rio Tinto Limited Annual General Meeting, 2023, Perth **Check against delivery** Thank you, Dom. First, I would like to acknowledge and pay my respects to the Whadjuk people of the Noongar Nation on whose Traditional Lands we are meeting today. And I pay my respects to all Traditional Owners and Indigenous people that host our operations around the world. Last year was a year in which we made progress towards building an even stronger Rio Tinto. We delivered during the year, and we invested in the health of our business and shaped our portfolio for the future. This year we celebrate Rio Tinto’s 150th anniversary. Throughout our history, our business has changed in response to the world around us, and the opportunities created by technology and international development. Our very first project was the redevelopment of an ancient copper mine in the south of Spain that gave our company its name. The Rio Tinto copper deposits have been mined on and off for more than 5,000 years. Many civilisations, from the Phoenicians to the Romans, were drawn to Spain by the wealth of those mines. However, by the time the Romans left it was thought that the accessible deposits had been exhausted, and the site was largely abandoned. The mines were re-opened in the 19th Century by a Spanish King who was desperate for cash, but they were badly run and losing money. When the King eventually lost his throne, the new government decided to sell the mine. Buying a loss-making mine with a depleted resource in a country recovering from civil war was seen as mad at the time. But a group of investors in London saw an opportunity. And on 29 March 1873, they formed the Rio Tinto Company to purchase and develop the mine. Their vision paid off, and they turned that run-down operation into one of the most profitable mines in Europe. They introduced modern mining techniques, equipment and infrastructure. New technology allowed them to extract copper from what others had dismissed as waste. And within ten years, the Rio Tinto Company was the largest copper producer in the world. This story illustrates the importance of vision, and the potential for innovation to transform entire industries. The ability to recognise potential, use innovation and achieve success has been key to Rio Tinto over 150 years. Exhibit 99.2

Notice to ASX 2 / 5 This story also ties perfectly with our new purpose: Finding better ways to provide the materials the world needs. Our purpose speaks to our drive for innovation, continuous improvement and impeccable ESG performance, and connects our contribution to everyday life, our customers, the communities where we operate, and society at large. Our purpose builds on the four objectives introduced when I became Chief Executive: • To become the best operator • To strive for impeccable ESG • To excel in development • And to strengthen our social licence. Coupled with our values of care, courage and curiosity, these are the foundations for our culture and guide our people day in and day out. They underpin our strategy, launched in 2021, which has climate at its heart and sets out the long-term pathway for Rio. Financial performance We delivered strong financial results, with underlying earnings of US$13.3 billion and a return on capital employed of 25%. Profit after tax attributable to Rio Tinto shareholders was $12.4 billion and our balance sheet remains strong with net debt of $4.2 billion. As a result, the Board has recommended a final ordinary dividend of 225 US cents per share, resulting in $8 billion of total returns to you, our shareholders. This represents a pay-out ratio of 60%, in line with our policy and the second-largest ordinary dividend in our 150-year history. Since 2020 we have achieved $47 billion in earnings, paying $29 billion in taxes and royalties, investing $20 billion in the business, and returning $33 billion to our shareholders. These consistently strong financial results through a period where we have seen continually evolving challenges highlight the underlying strength of the business, our world-class assets and our great people. Safety Most importantly, 2022 was our fourth consecutive fatality-free year. But we continue to see serious incidents in our business and therefore we must continue to focus, every day, on strengthening our safety culture. Much of the success is the result of work implemented through our Safety Maturity Model, which provides a roadmap for our leaders. This is about bringing together best practices from across the business and beyond to inform and improve our risk management and work planning. Best operator As I visit sites around the world, what I am seeing gives me confidence that we are on the right track to restoring our DNA of being the best operator. Changing our culture is key to achieving not only this, but each of our four objectives. When people feel respected and valued, they feel empowered to be their best selves and bring their best ideas. For example, our Safe Production System (SPS) relies on this – unlocking the potential of our employees, their skills and expertise, and creating stable, predictable operations.

Notice to ASX 3 / 5 I’ve been impressed by our progress in 2022, achieving a number of operational records, including a record second half performance across the Pilbara iron ore mine and rail system. We now have 30 deployments at 16 sites and 86 Kaizens, which are rapid problem-solving activities, completed or in progress. We are seeing excellent results. Where we have been deploying the SPS, we have sites that are safer, more engaged employees, and assets that are more productive. We will continue to deploy the SPS to more sites in 2023. Coupled with our investment of $3.9 billion in sustaining capex and a more active approach to maintenance, this means our assets are in better health than this time last year. More broadly, we are embedding a change in mindset and behaviours throughout the organisation, with the implementation of the Everyday Respect Report recommendations being absolutely crucial to driving this change. Achieving culture change – and our objective of best operator – will take time, but we are heading in the right direction. Impeccable ESG We have been working hard to implement meaningful change in the way we partner, especially with Indigenous peoples and the communities where we work. Moving to a model of co-management of country, and improving our agreements, will deliver more enduring socioeconomic, heritage and environmental outcomes and, in turn, greater certainty for mine development. And we have continued to develop cultural competency across the Group to help us become a better partner. A real highlight was the agreement with the Puutu Kunti Kurrama and Pinikura people to create the Juukan Gorge Legacy Foundation as part of the remedy for the destruction of the rock shelters in May 2020. This is a significant step forward, but we know it will be a long journey to rebuild trust. In addition, we have signed new agreements with the Yindjibarndi and Yinhawangka peoples in Australia, and the Pekuakamiulnuatsh First Nation in Canada. We are committed to this journey and recently published an independent report by ERM based on a global audit of our Cultural Heritage Management compliance and performance. It identified areas where we are achieving leading cultural heritage practices but also other areas where we need to improve. We know we have more work to do and will adopt all of the recommendations. On decarbonisation, it is early days and we have not advanced our abatement projects as fast as we would like. But despite that, our Scope 1 and 2 emissions were 7% below our 2018 baseline. It is important to note that this is a multi-decade journey and today we have a more robust roadmap to our 2030 and 2050 targets. We are ramping up our technical skills, building competencies and capabilities, and forming partnerships across our value chain to find solutions to some of the bigger challenges we are facing. We have set up six large abatement programmes focused on the decarbonisation challenges that cut across our product groups. We have also established one additional programme to increase our investments in nature-based solutions projects and expect these to make a contribution to our targets. Some of the technology we need to reach net zero by 2050 quite simply does not exist today.

Notice to ASX 4 / 5 We have established the Office of the Chief Scientist that is focused on helping us to build on the knowledge and expertise we already have in this space, and we have increased our yearly research and development target spend to $400 million. We know we can’t solve these challenges alone, so partnering with other organisations to find solutions is central to our approach. Our ELYSIS partnership to develop emissions-free aluminium smelting technology is a good example of this. Excel in development Through our acquisitions of Turquoise Hill Resources and Rincon, we are growing in materials essential to the energy transition and strengthening our ability to deliver strong returns for you in the long term. I recently joined the Prime Minister of Mongolia to mark the start of underground production of copper from Oyu Tolgoi, a significant milestone following the reset of our relationship with the Government. Now that we are a direct owner of Oyu Tolgoi, we are able to work much closer together to ensure all stakeholders benefit from this world class project. We achieved another important milestone at the Simandou iron ore project, incorporating the infrastructure joint venture with our various partners and the Government of Guinea. I hope we will soon see this major project moving into full execution for the benefit of the people of Guinea and providing the world a supply of the highest quality iron ore that can be turned into steel with much less CO2 emission. Licence to operate I recently travelled to China for the first time as Chief Executive, following time spent through the year with customers, suppliers, governments, communities, civil society and other stakeholders here in the UK, in Mongolia, Canada, Japan, Australia, the US and many other countries. As we strive to become a more outward-looking company, we will continue to listen and engage broadly. What I am hearing is a growing awareness of the importance of mining to achieving the energy transition and strengthening supply chain security. Putting climate at the heart of our strategy is both the right thing to do, and the right business decision. Over the coming years, we will continue to invest in moving from ambition to solutions, and in fostering the partnerships that will be essential to address this complex challenge. Conclusion I am proud of our continued progress through 2022. We have real momentum into our 150th year and a clear pathway for a strong future. We have defined our purpose, and are delivering against our strategy for the company to grow and decarbonise. We are evolving our culture, supported by simple, human values. Most importantly, we have an extraordinary team of talented and committed people around the world, and we are engaging to learn from the communities, customers and stakeholders around us. This is how we are building a stronger Rio Tinto, and finding better ways to deliver the materials the world needs. Thank you.

As previously announced, Shining Prospect (a subsidiary of the Aluminium Corporation of China “Chinalco”) voted against Resolution 21. Chinalco has not sold any of its shares in Rio Tinto plc and now has a holding of over 14% given its non-participation in the Company’s significant share buyback programmes. This places Chinalco close to the 14.99% holding threshold agreed with the Australian Government at the time of its original investment in Rio Tinto.

Notice to ASX/LSE 5 / 12 Appendix 1 FINAL PROXY POSITION Shareholders are encouraged to look at the voting figures provided in the main part of this announcement, as proxy figures may not be an accurate indication of the voting at the annual general meetings; a proxy is an authority or direction to the proxy holder to vote and not a vote itself. As such, the proxy figures do not reflect the votes cast by shareholders who attend the meeting in person, or through an attorney or corporate representative. References in this appendix in respect of resolutions 1-18 to an appointment specifying that a proxy abstain on a resolution should, when referring to voting at Rio Tinto plc’s annual general meeting, be taken as references to the appointment specifying that the proxy withhold from voting on a resolution. The proxy position for each company (excluding the proxy votes carried from one meeting to the other meeting by the Special Voting Shares in accordance with the DLC structure) on the resolutions put to both Rio Tinto plc and Rio Tinto Limited shareholders under the joint electoral procedure was as follows: PROXY POSITION FOR RIO TINTO PLC AND RIO TINTO LIMITED ON JOINT DECISIONS Rio Tinto plc Rio Tinto Limited 1.
