We were profoundly shocked and saddened by the deaths of two of our colleagues, Mr Cristovão Alberto Tonela and Mr Alfredo Francisco Domingos João, at Mozal Aluminium in November 2022. On behalf of the Board, I express my sincere and deepest sympathies to their families, friends and colleagues. This incident was devastating for everyone at South32 and has challenged each of us to ask ourselves every day whether our decisions and actions guarantee our own safety and that of our colleagues. We had already commenced our journey to fundamentally shift our safety performance and deliver the cultural transformation required for sustained improvement. The tragic loss of our colleagues at Mozal Aluminium has demonstrated why this work is of utmost importance and strengthened our resolve to eliminate fatalities and serious injuries from our business. We believe that supporting all our people to feel safe, included and respected at work can enhance individual and collective performance. The Board, working with the Lead Team, sets the direction and tone for our workplace culture and our focus is on building a culture that aligns with our purpose, reflects our values and supports the delivery of our strategy. Our Board represents a broad cultural, ethnic, background and geographic mix. In May we welcomed Mr Carlos Mesquita and Ms Jane Nelson as independent Non-Executive Directors, based in the Americas. The appointments of Carlos and Jane further enhance the Board’s broad range of skills and experience, particularly in major projects, operations and sustainability. We also farewelled Mr Guy Lansdown who resigned from our Board in May. I would like to thank Guy for his valuable contribution during his tenure as we expanded our presence in the Americas. As part of the Board’s program of regular meetings, Directors visited Hillside Aluminium, Hotazel Manganese Mines and Mozal Aluminium, as well as the Hermosa project in FY23. These site visits presented an opportunity to better understand the local operating context, consider the challenges and opportunities at each site, connect with our employees and contractors, and experience our culture first-hand. It has been inspiring to see how our people are making a difference at each of these locations as we all work to fulfil our purpose. Against this volatile and uncertain backdrop, we set annual production records at three of our operations and delivered one of our largest underlying profit results to date, with Underlying earnings before interest, tax, depreciation and amortisation of US$2.5 billion. This was achieved despite lower commodity prices and industry-wide inflationary pressures. We recorded a statutory loss after tax of US$173 million following the recognition of a non-cash impairment expense in relation to the Taylor Deposit at our Hermosa project, and ended the financial year with net debt of US$483 million as we made record returns to shareholders and invested in our business. “We published our first Climate Change Action Plan in September 2022 and received strong shareholder support for the Plan." The global economy has seen two successive major shocks in a short span of three years. While the world has re- opened since the COVID-19 pandemic, geopolitical tensions remained heightened throughout FY23, including the ongoing tragic war in Ukraine and strained ties between the major economic centres. This has contributed to market fragmentation and volatility in a landscape where policymakers and companies are already grappling with structural risks including climate change, higher sovereign debt levels, ageing demographics and rising income inequalities. We returned US$1.2 billion to shareholders during FY23, including US$1,007 million in fully-franked ordinary and special dividends, and US$218 million via our on-market share buy-back. Reflecting our disciplined approach to capital management, the Board has resolved to further expand our capital management program to US$2.4 billion, leaving US$133 million to be returned by 1 March 2024. One of the central aims of the United States Inflation Reduction Act is to increase investment in clean energy, offering tax incentives for domestic electric battery vehicle production and supply chains. The Hermosa project 2 OPERATING AND FINANCIAL REVIEW With a referendum on an Indigenous Voice to Parliament taking place in Australia in October 2023, our hope is that everyone takes the time to inform themselves on what this means to the First Nations Peoples of Australia and the broader community. The Board is pleased with the progress that has been made in FY23, while acknowledging that we must continue our critical work to improve our safety performance. We have much to look forward to in FY24, as we continue to transform our portfolio to provide commodities critical to a low-carbon future. On behalf of the Board, I would like to thank our shareholders, communities and other key stakeholders for their ongoing support and reiterate our thanks to our people for their hard work and commitment throughout the year. Karen Wood Chair supports this anticipated growth and is currently the only advanced project in the United States that could supply two federally designated critical minerals, zinc and manganese. The development of Hermosa is an important step in our long-term strategy to reshape our portfolio by increasing our exposure to commodities critical to a low-carbon future. Our ambition is for Hermosa to be our first next generation mine with the potential to deliver improved safety and productivity while minimising our environmental impact and making a significant contribution to our host communities and the local economy. We are progressing the Taylor and Clark Deposits towards development, with a final investment decision on Taylor expected by the end of calendar year 2023. Taking action to address the risks and opportunities which climate change presents is also a long-term focus for our business. We support the goals of the Paris Agreement and have a long-term goal to achieve net zero greenhouse gas (GHG) emissions by 2050, inclusive of Scope 1, 2 and 3 emissions. We also have a medium-term target to halve our operational GHG emissions (Scope 1 and 2) by 2035 from our FY21 baseline. We published our first Climate Change Action Plan in September 2022, which was the subject of a non-binding advisory resolution at our 2022 Annual General Meeting. The Plan received strong shareholder support, with 89.6 per cent of votes cast in favour of the resolution. Subsequent to the meeting, we engaged with material shareholders that voted against the Plan to understand areas they would like to see improved and this feedback is taken into consideration by our Board in determining our approach to climate change going forward. We have made progress against key elements of the Plan in FY23, including updating our 1.5°C scenario to stress-test the potential impacts of climate change on our business. We have also progressed our decarbonisation initiatives with a focus on the operations which account for the majority of our GHG emissions profile. The Board oversees climate change as a strategic risk and material governance issue, and we will continue to provide annual updates on our progress against our Climate Change Action Plan in our Sustainable Development Report. Just as we continue to share our approach and performance on climate change, the same is also true for other material sustainability topics, with the publication of new or updated approaches for Indigenous, Traditional and Tribal Peoples Engagement, Cultural Heritage, Human Rights, Water Stewardship, and Tailings Management. In 2020 we announced our support for the Uluru Statement from the Heart as the pathway towards reconciliation put forward by Australia’s First Nations Peoples, which includes enshrining a First Nations Voice to Parliament into the Australian Constitution. We are aware that there are many different views on how to address the considerable disadvantage of Australia’s First Nations Peoples. As a Board we have a duty to act in the best interests of our company. Those interests include the way in which we operate on the lands of First Nations Peoples. It is in our interests that the communities that support our operations are thriving and, in our view, this will be supported by First Nations Peoples having a say on matters relating to them. 3 SOUTH32 ANNUAL REPORT 2023 OUR PURPOSE-LED APPROACH MAKING A DIFFERENCE...

Our operations, development options and exploration programs are diversified by commodity and geography. We work to minimise the impact of our activities and aim to create enduring value for our stakeholders, at each stage of the mining lifecycle. The resources we rely on What we do Explore Develop Refine/Smelt Mine/Process Market Rehabilitate and Close People and expertise Our global workforce is made up of both employees and contractors and is our most important resource, providing the skills, experience and technical expertise required to run our business. Natural resources The resources and reserves we access are the primary inputs for our business. Other natural resources such as water and energy are also important for the operation of our facilities, and we require access to land to conduct our business activities. Physical assets We have a suite of operations including open-cut and underground mines, refineries, smelters and associated infrastructure. We procure equipment from suppliers globally to support our operations, development options and exploration programs. Finance Our shareholders and lenders provide access to financial capital, which we put to work by operating our existing facilities and funding our pipeline of development options and exploration programs. Relationships Trust and transparency are essential to the way we operate. We seek to build trust in the communities where we operate to help realise the potential of their resources, and we work with our suppliers and customers to apply responsible business practices throughout our value chain. 10 OPERATING AND FINANCIAL REVIEW Explore We have a portfolio of more than 25 greenfield exploration options across the world to discover deposits to underpin our next generation of mines, with a focus on commodities critical to a low-carbon future. Wherever we explore, we work to minimise the footprint of our activities through the use of technology and well-designed programs. Develop Our development options have the potential to provide commodities which support the transition to a low-carbon world and we have a pipeline of options in feasibility, pre-feasibility and other study phases. As we advance these options we are looking to reshape the way we would mine at future projects including the Hermosa project to deliver transformational safety, productivity and emissions outcomes. Mine/Process We mine and process bauxite, copper, silver, lead, zinc, nickel, metallurgical coal and manganese. Our most important commitment at all of our sites is the health, safety and wellbeing of our employees, contractors, visitors and communities. We listen to our stakeholders and work together with the aim of creating shared value. Refine/Smelt We refine bauxite to produce alumina, we smelt alumina to produce aluminium, and we smelt nickel ore to produce ferronickel. We are also executing decarbonisation initiatives to support delivery of our operational decarbonisation target, focusing on our highest emitting refineries and smelters. Market We generate revenue from the sale of our commodities to a global customer base and purchase raw materials from global markets. We also analyse commodities and their markets to inform our strategic business planning and investment decisions. We are building meaningful partnerships with key customers and suppliers to support and co-design emissions reduction programs in the value chain. Rehabilitate and Close From exploration through to closure and beyond, we seek to minimise our adverse impacts on the surrounding communities and environments. We undertake progressive rehabilitation where possible, our closure plans are informed by the aspirations and expectations of our host communities and countries, and we aspire to leave a positive legacy.

Key market sectors where our commodities have an important role to play include construction, energy and renewables, the automotive industry and consumer goods. Aluminium Copper Silver, Lead, Zinc Aluminium is often referred to as the metal of the future. It is lightweight, durable, strong, resistant to corrosion, recyclable and it can conduct electricity, meaning it has a wide range of applications including construction, electrical wiring, transportation, packaging and consumer goods such as electronics and household items. We have doubled our low-carbon aluminium(1) capacity and operate the largest aluminium smelter in the southern hemisphere. Copper is a key metal used in electric vehicles and charging infrastructure. It is also an excellent conductor of electricity. As the world moves towards electrification, copper will increasingly be used in power-related infrastructure, including renewable energy. Copper is also used in kitchen cookware and plumbing as it conducts heat well and has antimicrobial properties. In FY22 we acquired an interest in our first operating copper mine, which transitioned to 100 per cent renewable electricity supply in FY23. Silver is used in solar panels due to its superior electrical conductivity, and is also used to make medical appliances and consumer electronics. Lead is used in renewable energy storage systems. Zinc protects metals against corrosion and will play a key role in green infrastructure development as a protective coating for wind turbines and solar panels. In solar panels zinc oxide coatings help achieve higher energy conversion. We are a large producer of silver-rich lead concentrate and zinc concentrate. (1) A definition of the term 'low-carbon aluminium' when used in the context of climate change is set out in the Glossary of terms and abbreviations on page 185 of this report. 14 OPERATING AND FINANCIAL REVIEW FY23 production at a glance Aluminium (kt) 1,133 Zinc (kt) 59.2 Copper (kt) 70.7 Nickel (kt) 40.8 Silver (koz) 11,813 Lead (kt) 101.7 Metallurgical coal (kt) Manganese (kwmt) 5,497 5,653 + Learn more about our portfolio in a low-carbon world in our Sustainable Development Report at www.south32.net Nickel Metallurgical coal Manganese Nickel is used in stainless steel, which is used in transportation, manufacturing, household items and surgical instruments. Nickel has an important role to play as the world transitions to a more sustainable future as it is used as an alloy in wind and solar power infrastructure. Nickel-rich batteries are also critical for the rapid adoption of electric vehicles. We are one of the world’s largest ferronickel producers with the potential to produce intermediary products for electric vehicles. Currently there is no commercial scale alternative to metallurgical coal in the steelmaking process. The use of high- quality metallurgical coal that we produce supports greenhouse gas emissions reduction targets in the steel industry through improved blast furnace efficiency, when compared with lower-quality metallurgical coal. Growth in steel demand is anticipated for green infrastructure development and vehicle electrification, as well as for the establishment of new steel capacity in emerging markets. Manganese is used to improve the quality and strength of steel in major infrastructure such as hospitals, office towers and bridges. Manganese also has the potential to displace cobalt in lithium-ion batteries, with demand for manganese-rich cathode chemistries expected to grow. We are well positioned to meet future demand as we are the world’s largest producer of manganese and our Hermosa project has the potential to produce battery-grade manganese. 15 SOUTH32 ANNUAL REPORT 2023 FROM THE CEO DELIVERING NOW AND FOR THE FUTURE Our strategy continues to serve us well and we delivered strong growth in commodities critical to a low-carbon future. We are investing to grow our business, have made substantial progress at our Hermosa project and are maturing our decarbonisation efforts. Nothing is more important than the health, safety and wellbeing of our people. Unfortunately, we did not deliver on our most important commitment in FY23. In November 2022, we were devastated by the loss of two of our colleagues, Mr Cristovão Alberto Tonela and Mr Alfredo Francisco Domingos João, who were fatally injured in an incident while undertaking maintenance work on a raising girder at Mozal Aluminium. Our deepest sympathies remain with their families and colleagues. I visited Mozal Aluminium following the incident and its impact caused great sadness for all of us. Our initial priorities were to care for those involved, and respond to the immediate potential risk for the remaining raising girders by implementing additional controls at both Mozal Aluminium and Hillside Aluminium. We owe it to everyone who has been affected by the deaths of Mr Tonela and Mr Domingos to learn from this terrible event. We worked with the original equipment manufacturer to identify further safety improvements, and once the investigation was completed, key learnings were shared across our business and our industry. Our Lost Time Injury Frequency (LTIF) decreased by 30 per cent compared to the FY22 baseline and our Total Recordable Injury Frequency (TRIF) increased by 11 per cent compared to the FY22 baseline. LTIF is a measure of serious injuries whereas TRIF is a measure of all recordable injuries, so although we saw an increase in recordable injury events, the frequency of severe events decreased. Despite this, we recognise that we must continue to improve our health and safety performance and everyone, across all levels of our organisation, are focused on this. We continue to implement our multi- year Safety Improvement Program that commenced in FY22, which aims to deliver the cultural transformation required for sustained improvement. We have also made changes to the structure of our health and safety teams to continue to drive the integration between culture and health and safety. Every day, we ask our people to reflect on whether they can guarantee both their safety and that of their colleagues when executing their role. If the answer is no, then the challenge is to stop work and ask what would need to be done differently to provide that guarantee. This is articulated as our ‘safety guarantee’ and it is used to create a sense of chronic unease, reduce complacency, and assist to reduce risk tolerance. We are working to further embed our 'safety guarantee' across our business. We made some changes to our Lead Team in FY23, with Katie Tovich moving from the Chief Financial Officer role to become our Chief Human Resources and Commercial Officer, and we appointed Sandy Sibenaler as our new Chief Financial Officer following an internal promotion. With these changes, we have 50 per cent female representation on our Lead Team and while we continue to focus on increasing gender balance across the business, ultimately inclusion and diversity is about our workforce reflecting the communities in which we operate. Inclusiveness extends beyond the workplace and in Australia, we support an Indigenous Voice to Parliament as a key element of the Uluru Statement from the Heart. We mine on Indigenous lands, and as part of determining our own position on the Statement we consulted the “Recent portfolio improvements have helped us deliver strong production growth in aluminium, base metals and manganese.” In the same way that we are working to create workplaces that are physically safe, we are also focused on creating workplaces that are psychologically safe. We manage sexual harassment as a material health and safety risk and have implemented additional controls and safety measures which aim to mitigate against the potential for sexual harassment to occur in our workplaces, focusing on our highest exposure areas such as accommodation facilities. We know that an inclusive and diverse workforce produces better outcomes and we are working to instil a culture that supports a positive employee experience and a safe and productive workplace. Traditional Owner Groups and Registered Indigenous Groups where we operate to confirm their support of the Statement. This year we have created opportunities for discussion and learning, including panel discussions with Indigenous Australians from where we operate, so that when our people decide whether to support a Voice to Parliament, they do so in an informed way. The macroeconomic environment remained volatile throughout FY23. Inflationary pressures persisted in many jurisdictions which lead to an unprecedented pace of interest rate rises 16 OPERATING AND FINANCIAL REVIEW by major central banks which impacted demand, particularly industrial activity. Although China reopened from its zero- COVID policy in the second half of the year, economic growth did not meet initial expectations. Despite the challenging operating environment, we achieved record annual production at Hillside Aluminium, Australia Manganese and South Africa Manganese, and had a strong finish to the year with Brazil Alumina, Cannington and Illawarra Metallurgical Coal returning to stable operations following adverse weather and other temporary impacts. Underlying earnings decreased as the combination of a decline in commodity prices from record levels in many markets in the prior period, and higher inflation and uncontrollable costs, more than offset higher production volumes. We continue to prioritise a strong balance sheet and investment grade credit rating through all cycles, finishing the period with net debt of US$483 million as we made record returns to shareholders during FY23 and invested to grow our future production of commodities critical to a low-carbon future. Our strategy of optimising the performance of our operations, unlocking their potential and identifying new opportunities to create value for our stakeholders has helped us navigate economic cycles over the last eight years. Recent portfolio improvements have helped us deliver strong production growth, with aluminium production increasing by 14 per cent, base metals by 17 per cent and manganese by 4 per cent in FY23. We have made substantial progress at our Hermosa project in the United States. Hermosa is currently the only advanced project in the United States that could supply two federally designated critical minerals, zinc and manganese, which are important for a low-carbon future. In May 2023, Hermosa was confirmed as the first mining project to be added to the FAST-41 process, enabling a more efficient and transparent federal permitting process for the project. We have recognised a non-cash impairment expense for the Taylor Deposit at Hermosa with our FY23 financial results, due to delays from the impact of COVID-19, the significant dewatering requirements and current inflationary market conditions. We continue to see substantial opportunity to unlock additional value across the Taylor and Clark Deposits and our highly prospective regional exploration package. In July 2023, we released an updated Mineral Resource estimate for Taylor, including a 41 per cent increase in the Measured Mineral Resource, providing a compelling base to underpin future production. In the second half of calendar year 2023 we expect to complete the feasibility study and make a final investment decision for Taylor. Separately, study work for the Clark Deposit at Hermosa has confirmed its potential to supply battery-grade manganese to the rapidly forming North American electric vehicle supply chain. Study work is continuing, pilot plant production has commenced and decline construction is expected to commence in the first half of FY24. We are encouraged by the exploration options across our regional land package at Hermosa, including our high priority Peake and Flux Prospects, with recent drilling at Peake delivering our best copper exploration results to date. We continue to invest to discover deposits to underpin our next generation of mines and during the period we exercised our earn-in right to acquire a controlling stake in the Chita Valley copper exploration project in the highly prospective San Juan province of Argentina. Our development options and exploration activities form part of our approach to climate change. We published our first Climate Change Action Plan in September 2022 and have continued to mature our decarbonisation efforts, including commencing the conversion of Worsley Alumina’s first coal-fired boiler to natural gas and deploying the AP3XLE energy efficiency technology at Hillside Aluminium. In addition, we progressed decarbonisation studies at Hillside Aluminium, Worsley Alumina and Illawarra Metallurgical Coal. For Hillside Aluminium, while our studies have confirmed the challenges associated with developing renewable and low- carbon energy sources in South Africa, we continue to investigate a range of potential solutions including acquiring energy attributes to reduce the emissions intensity of its product in the near-term. At Mozal Aluminium, we are working to extend the supply of hydro-electric power beyond 2026. Despite the headwinds experienced in FY23, and the expectation of continued macroeconomic challenges in FY24, we are continuing to deliver results now and create value for the future. I would like to thank all our teams around the world for their contribution to our performance and progress as we solidify our position as a global, diversified producer of commodities critical to a low-carbon future. Graham Kerr Chief Executive Officer 17 SOUTH32 ANNUAL REPORT 2023 OUR STRATEGY A STRATEGY TO ACHIEVE OUR PURPOSE Our purpose is at the heart of who we are. Every day, in support of our purpose and underpinned by our approach to sustainability, our people work to deliver our strategy for the benefit of our stakeholders. Our purpose is to make a difference by developing natural resources, improving people's lives now and for generations to come. We are trusted by our owners and partners to realise the potential of their resources. Our purpose is underpinned by a simple yet powerful strategy. We optimise our business by working safely, minimising our impact, consistently delivering stable and predictable performance, and continually improving our competitiveness. We unlock the full value of our business through our people, innovation, projects and technology. We identify and pursue opportunities to sustainably reshape our business for the future, and create enduring social, environmental and economic value. Sustainability is at the heart of our purpose and underpins the delivery of our strategy. Our approach to sustainability comprises five interconnected pillars which focus on areas that are material to our business and stakeholders. Protecting and respecting our people Delivering value to society Operating ethically and responsibly Managing our environmental impact Addressing climate change While our business has many positive impacts, we also recognise that our business activities have the potential to cause adverse impacts. We are committed to continuously improving our sustainability performance, optimising our positive contributions and minimising adverse impacts. + Learn more about our approach to sustainability in our Sustainable Development Report at www.south32.net. 18 OPERATING AND FINANCIAL REVIEW Delivering our strategy We deliver on our purpose and our strategy by aligning our workforce behind seven ‘breakthroughs’ – commitments which shape our annual business planning process at corporate, operational and functional levels, enabling us to focus on what’s important. Our first breakthrough is ‘we all guarantee everyone goes home safe and well’, which asks each person in our workforce to take responsibility for their own safety and wellbeing, and that of their colleagues. Our 'safety guarantee' is an internal approach that is used to create a sense of chronic unease, reduce complacency, and assist to reduce risk tolerance. Risk framework and corporate governance We are governed by robust risk management and corporate governance frameworks. Learn more in our Risk management section on pages 28 to 37, and in our Corporate Governance Statement at www.south32.net. Climate-related financial disclosures Our climate-related financial disclosures, which we consider to be consistent with the four recommendations and the 11 recommended disclosures of the Task Force on Climate-related Financial Disclosures (TCFD) are set out in the Addressing Climate Change section of our Sustainable Development Report and the Emissions Methodology tab in our Sustainability Databook, both of which are available at www.south32.net. In addition, certain disclosures in connection with the governance-related recommendations and recommended disclosures can be found in our Corporate Governance Statement which is also available at www.south32.net. We have included our TCFD-aligned disclosures in the separate Sustainable Development Report and Sustainability Databook to enable us to provide them alongside detailed information on our Climate Change Action Plan and the progress we have been making, in the context of our sustainability activities more widely, and in our Corporate Governance Statement so that they are discussed in the context of our corporate governance arrangements more generally. This Annual Report should therefore be read in conjunction with the Sustainable Development Report, the Sustainability Databook and the Corporate Governance Statement. You can find a table setting out each of the TCFD's 11 recommended disclosures, and where information relating to each recommended disclosure can be found, in our Sustainability Databook (see the TCFD Index tab) which is available at www.south32.net. Capital management framework Our simple strategy is underpinned by a disciplined approach to capital management. Our capital management framework remains unchanged, supporting investment in our business and rewarding shareholders as our financial performance improves. Our capital allocation priorities are to maintain safe and reliable operations and an investment grade credit rating through the cycle. We intend to distribute a minimum of 40 per cent of Underlying earnings as ordinary dividends to our shareholders following each six-month reporting period. We encourage internal competition for excess capital, which can include further investment in new projects, acquisitions, greenfield exploration, share buy-backs or special dividends. We returned US$1,225 million to shareholders during FY23 via ordinary dividends, special dividends and our on-market share buy-back. The Board further expanded our capital management program to US$2.4 billion in August 2023, leaving US$133 million to be returned by 1 March 2024. Capital allocation since FY16 2% 22% 38% US$14.7b allocated 16% 22% Capital expenditure (including equity accounted investments) Ordinary dividends Capital management program Acquisitions Greenfield exploration SOUTH32 ANNUAL REPORT 2023 19 OUR STRATEGY IN ACTION Working safely Our FY23 commitments: 〉 At least 80 per cent senior leader attendance at LEAD Safely Every Day workshops and coaching sessions; 〉 A reported significant hazard frequency of 55; 〉 A 20 per cent reduction in Lost Time Injury Frequency (LTIF)(1) against the FY22 baseline, and a 10 per cent reduction in Total Recordable Injury Frequency (TRIF)(2) against the FY22 baseline; and 〉 A 20 per cent reduction in potential material health exposures against the baseline. Progress during the year: In November 2022, we were devastated by the loss of two of our colleagues, Mr Cristovão Alberto Tonela and Mr Alfredo Francisco Domingos João, who were fatally injured in an incident while undertaking maintenance work on a raising girder at Mozal Aluminium. Our deepest sympathies remain with the families and colleagues of the deceased to whom we provided our support and counselling. An investigation into the incident was completed and key learnings were shared across our business and our industry. Every day, we ask our people to reflect on whether they can guarantee both their safety and that of their colleagues when executing their role. If the answer is no, then the challenge is to stop work and ask what would need to be done differently to provide that guarantee. This is articulated as our ‘safety guarantee’ and it is used to create a sense of chronic unease, reduce complacency, and assist to reduce risk tolerance. We are working to further embed our 'safety guarantee' across our business. We also disclose fatalities for contractor activities that are associated with our operations, but that take place in locations where we do not have control. In FY23, an employee from a company contracted by South Africa Manganese lost their life in an off-site road trucking accident. We recognise that we must continue to improve our health and safety performance. We are focused on building a culture of safety and continuously improving our safety leadership, behaviours, processes, and systems to eliminate fatalities, serious injuries and illnesses. We continue to implement our Group-wide Safety Improvement Program, a multi-year global program of work launched in FY22 and designed with the aim of enhancing our safety culture and by changing mindsets and behaviours, achieving a step change in our safety performance. One of the key focus areas of the Safety Improvement Program is shifting mindsets through leadership. To help achieve this, in FY23 we rolled out a program called LEAD Safely Every Day, which comprises workshops and coaching for senior leaders, managers, superintendents and supervisors across all operations and functions. With 99 per cent of our senior leaders completing the workshops and coaching sessions in FY23, in FY24 we plan to extend the roll out of the LEAD Safely Every Day program to frontline employees and frontline contractors. Learn more about the LEAD Safely Every Day program in our Sustainable Development Report at www.south32.net. Proactive hazard reporting is an important part of our approach to safety, and we exceeded our target with a reported significant hazard frequency of 92, indicating a positive reporting culture and increased hazard awareness and identification. Our LTIF decreased by 30 per cent compared to the FY22 baseline, exceeding our target, and our TRIF increased by 11 per cent compared to the FY22 baseline, falling short of our target. This outcome is primarily attributed to an increase in recordable injuries reported during the financial year. Although we saw an increase in recordable injury events, the number of lost time injury events decreased, resulting in our lowest ever LTIF. The number of people potentially exposed to material health exposures against the baseline increased by one per cent, falling short of our target. While we saw a significant reduction in potential material exposures at some operations, an increase in employee numbers in certain exposed job groups, as well as production factors, led to an increase in potential material exposures at others. (1) Per million hours worked. Incidents are included where South32 controls the work location or controls the work activity. Lost time injuries include injuries that result in one or more lost work days after the day of the event. (2) Per million hours worked. Incidents are included where South32 controls the work location or controls the work activity. 20 OPERATING AND FINANCIAL REVIEW OPTIMISE OUR BUSINESS Stable and predictable performance while minimising impact Our FY23 commitments: 〉 Revenue equivalent production within 97 to 102 per cent of budget(3); 〉 Controllable costs within US$50 million of budget (adjusted for foreign exchange, price-linked costs and other adjustments)(3); 〉 Capital expenditure (excluding growth projects) within five per cent of budget (adjusted for foreign exchange) and fewer than 20 per cent break-in capital projects(3); 〉 Capital expenditure on growth projects within 10 per cent of budget (adjusted for foreign exchange) and schedule(3); and 〉 Achieve budget adjusted return on invested capital (ROIC)(4). Progress during the year: We achieved 95 per cent of budgeted revenue equivalent production. We achieved record annual production volumes at Hillside Aluminium, Australia Manganese and South Africa Manganese, and we had a strong finish to the year with other operations including Cannington and Illawarra Metallurgical Coal returning to stable operations following adverse weather and other temporary impacts. For more information on our operating performance, see pages 48 to 58. Controllable costs were US$28 million above budget, predominantly due to higher contractor and maintenance costs. Capital expenditure excluding growth projects was 94 per cent of budget, as we invested in the Appin mine at Illawarra Metallurgical Coal and progressed productivity and decarbonisation initiatives at Worsley Alumina and other operations; and there were 70, or 14 per cent, break-in capital projects. Capital expenditure on growth projects, which was focused on the Hermosa project, was 88 per cent of budget and delivered on schedule, as we progressed studies for the Taylor and Clark Deposits and developed essential infrastructure. The adjusted ROIC was 26.4 per cent against the budget of 28.1 per cent. + Learn more about how we seek to minimise our impact in Create social, environmental and economic value on page 24. Robot Dog to Help Improve Safety and Productivity At Cannington we are working with a technology provider to develop and test light detection and ranging (LiDAR) scanning and automation technology. ‘Spot’ the Robot Dog was put through its paces at Cannington in FY23 to trial its capabilities in a real underground mining environment. The technology has the potential to improve safety and productivity by deploying the autonomous capabilities of Spot in various scenarios, with different data capture tools including scanning, video recording and heat sensing. The focus of the trial was to test Spot's capabilities in post blast re- entry scenarios and emergency response. With an integrated LiDAR scanner, Spot autonomously navigated sections of the mine, travelling through uneven and wet ground, exploring unlit areas and producing a three dimensional point cloud map of the area. Since the initial trial, Spot has returned to Cannington for further scenario testing, including gas detection and additional post blast re-entry. (3) Excludes non-operated entities.

Progress during the year: Technology and innovation are key enablers of our transition towards a low-carbon future and to realising our objective of safer, cleaner and more productive operations. To focus our innovation investment in the areas that matter most, in FY21 we established Innovate32, our strategy-aligned, value-creating approach to better enable innovation at South32. One of Innovate32’s strategic focus areas is the Next Generation Mine Mission, which seeks to reshape the way we mine and operate, with a specific focus on future projects including the Hermosa project, to strive to deliver transformational safety, productivity and emissions outcomes. In FY23, eight priority initiatives were progressed across automation, electrification, sensing, advanced analytics, orebody knowledge, and high impurity processing technologies, with six, or 75 per cent, fully delivered and two partially delivered. Another area of focus for Innovate32 is the Low Footprint Mission which aims to actively reduce our footprint with respect to energy and water use, waste generation and biodiversity impact. In FY23 we refreshed our competitive ambition and roadmap of opportunities, and doubled our portfolio of funded initiatives. We actively collaborate with other companies, industry groups and research organisations to complement our innovation and technology programs through initiatives such as the Electric Mine Consortium, BluVein, Amira, the Heavy Industry Low-Carbon Transition Cooperative Research Centre, the Long Duration Energy Storage Council, the Think and Act Differently industry joint venture, and a partnership with Unearthed to source ideas and solutions to unsolved problems. Learn more about these partnerships in our Sustainable Development Report at www.south32.net. 〉 Deliver the annual Inclusion and Diversity Action Plan; 〉 Maintain or improve our inclusion index score; and 〉 Maintain or improve our employee engagement score. Progress during the year: Our inclusion and diversity measurable objectives provide a series of targets and actions aimed at improving inclusion and diversity in our workplace. In FY23, we met the target for four of our eight measurable objectives. There are five measurable objectives for representation of employees and senior leaders who are women. The representation of women in our overall workforce improved, increasing to 20 per cent from 19 per cent in FY22, but falling short of our FY23 target of 22 per cent. The representation of women on our Lead Team increased to 50 per cent from 37.5 per cent in FY22 and exceeded our FY23 target of 38 per cent, the representation of women in our Senior Leadership Team decreased to 30 per cent from 32 per cent in FY22 and fell short of our FY23 target of 34 per cent, and the representation of women in our Operational Leadership Team(1) improved to 29 per cent from 20 per cent in FY22 and met our FY23 target of 28 per cent. The representation of women on our Board increased to 44 per cent from 37.5 per cent in FY22, meeting our FY23 target of at least 40 per cent. We maintained the representation of Black People in our workforce in South Africa, reaching 87 per cent and meeting our target of 85 per cent or more, however the representation of Black People in management roles in South Africa decreased to 55 per cent, below our target of 60 per cent or more. We continue to target pay equity for our employees with respect to gender and ethnicity and completed our annual equity pay review, investing US$338,000 to improve pay equity and narrowly missing our target of reducing spend year-on-year to close the pay gap. Our FY23 Inclusion and Diversity Action Plan consisted of four priority areas – managing sexual harassment as a material health and safety risk, providing safe and respectful workplaces for our people, establishing inclusion and diversity networks at all our locations, and delivering the 'Living our Code' discussion series, with substantial progress made in each area. In FY23, 7,358 individuals, or 78 per cent of employees, completed our annual Your Voice employee survey, the highest participation rate since South32 was formed in 2015. The survey tested five dimensions – safety, leadership, employee engagement, employee experience and workplace conduct, with respondents reporting an improvement in performance against all five dimensions. Based on the survey responses, our inclusion index score improved from 80 per cent in FY22 to 81.5 per cent in FY23 and our employee engagement score improved from 78 per cent in FY22 to 79 per cent in FY23. (1) In FY23 we have revised the Operational Leadership Team definition and calculation methodology to better reflect our organisational structure. FY22 data displayed is based on previous methodology as disclosed in the 2022 Sustainability Databook. 22 OPERATING AND FINANCIAL REVIEW UNLOCK THE FULL VALUE OF OUR BUSINESS Project execution Our FY23 commitments: 〉 Complete the Taylor Deposit feasibility study; 〉 Complete the construction of Hermosa Water Treatment Plant 2 and commence commissioning; 〉 Complete the Clark Deposit pre-feasibility selection study; and 〉 Identify battery partner options and advance discussions. Progress during the year: We have made substantial progress at our Hermosa project, which is currently the only advanced project in the United States that could supply two federally designated critical minerals, zinc and manganese, which are important commodities for a low-carbon future. In May, Hermosa was confirmed as the first mining project to be added to the FAST-41 process, enabling a more efficient and transparent federal permitting process for the project. In July 2023, we announced an update to the Mineral Resource estimate for the Taylor Deposit at Hermosa, including a 41 per cent increase in the Measured Mineral Resource(2). We have recently completed study work that confirmed that the Taylor Deposit and the Clark Deposit can be developed independently and have since recognised a non-cash impairment expense for the Taylor Deposit within our FY23 financial results, driven by delayed first production as a result of COVID-19 related restrictions and significant dewatering requirements, as well as capital cost escalation in line with industry-wide inflation. We continue to see substantial opportunity to unlock additional value across the Hermosa land package. We now expect to complete the feasibility study for the Taylor Deposit in the second half of calendar year 2023, as we undertake additional engineering studies to align the mine development schedule for a federal permitting process under FAST-41 and incorporate current market cost estimates, followed by a final investment decision expected by the end of calendar year 2023. Dewatering activity is progressing, enabling access to both the Taylor and Clark Deposits. The construction of Hermosa Water Treatment Plant 2 was completed in early June and commissioning is well advanced. Study work for the Clark Deposit has confirmed its potential to supply battery-grade manganese to the rapidly forming North American electric vehicle supply chain. The pre-feasibility selection study was completed in FY23 and has defined the potential for an underground mining operation and a separate plant to produce high-purity manganese sulphate monohydrate. Further study work is underway, pilot plant production has commenced and construction of an exploration decline is expected to commence in the first half of FY24. We continue to engage with potential customers, supported by multiple non- binding, non-exclusive memorandums of understanding for the future potential supply of battery-grade manganese. Hermosa also offers a highly prospective regional land package with the potential for future discoveries. Recent drilling results at the Peake Prospect include our best intercept to date(2). Further exploration drilling at Peake, along with drilling at the Flux Prospect, is planned in the first half of FY24. We have unlocked value at our existing operations in FY23 with the commissioning of the Ore Sorting and Mechanical Ore Concentration project at Cerro Matoso, which underpinned a 15-year extension to Cerro Matoso’s mining contract to 2044, and with the approval of the Eastern Lease South life extension project at Groote Eylandt Mining Company. At Cerro Matoso we are studying the potential to produce incremental volume in the form of intermediary nickel products for battery markets. We also announced our decision not to proceed the Dendrobium Next Domain project at Illawarra Metallurgical Coal. Rig Simulator Facility Helps Build New Skills Hotazel Manganese Mines (HMM) is unlocking value with the implementation of several growth projects at the Wessels underground mine. The projects include the implementation of new generation rigs, which aim to increase drilling depths to achieve a better advance per blast, and a fleet automation journey to help improve the safety and productivity of drilling and underground support processes. To support the introduction of the new rigs, a virtual production machine and rig simulators have been installed to train employees to operate them. As well as increasing advance per blast, the new rig technology offers improved data gathering and analysis. The establishment of these facilities in the Wessels training centre is helping equip our workforce with new skills which will benefit both them, and the operation, as the new technology is deployed.

Progress during the year: Social investment plans were implemented for each operation and we invested US$27.7 million in community initiatives(1). Our direct social investment spend was across our four key focus areas - education and leadership (24 per cent), economic participation (14 per cent), good health and social wellbeing (50 per cent), and natural resource resilience (12 per cent). We increased the proportion of social investment allocated to strategic investments with long-term objectives from 82 per cent in FY22 to 90 per cent in FY23. The economic value of our presence in communities is an important part of our societal contribution and we develop economic development plans as outlined in our internal social performance standard. These are complementary to our social investment plans and identify opportunities to contribute to local communities through employment, procurement, business development, and regional economic development. In FY23, economic development plans were developed for all operations. We believe that growing and developing small, medium, and micro enterprises (SMMEs) is fundamental to the transformation of the South African economy. We collaborate with SMMEs on Enterprise and Supplier Development (ESD) and in FY23 we exceeded our target for ESD with a total spend of US$15 million(2). In Australia, we remain committed to providing genuine access and support to build the capability and capacity of Aboriginal and Torres Strait Islander businesses where we have a presence, and our direct spend increased by 18 per cent to A$30 million. Learn more about how we are creating value for our stakeholders on pages 12 to 13. We continue to look for opportunities to improve water use. We have identified water-related material risks at five operations and have set contextual water targets for each, with two targets achieved and the others remaining on track. Currently, we have four operations in areas defined as having baseline water stress and for these a target was set in FY22 to achieve at least a 10 per cent improvement in water use efficiency by FY27, from an FY21 baseline. Cumulatively across these four operations, we achieved more than two per cent improvement in FY23, exceeding the target of more than one per cent improvement during the year. Around the world we have land holdings of 602,057 hectares. Cumulatively, we have disturbed approximately three per cent of our landholdings for operational reasons, of which approximately 33 per cent has been rehabilitated(3). We aim to achieve no net loss outcomes for all new projects and major expansions to existing projects, and in FY23 worked in partnership with others to pilot the adoption of the Taskforce on Nature-related Financial Disclosures, an emerging disclosure framework. We are also committed to implementing the Global Industry Standard on Tailings Management (GISTM) at all South32- operated tailings storage facilities and recently published our first GISTM report for our ‘very high’ consequence facilities, which are only at Worsley Alumina. Our approach to climate change is focused on reshaping our portfolio, decarbonising our operations (with a focus on the four operations which account for the majority of our operational emissions profile), responding to the potential physical impacts of climate change, and working with others to address shared challenges and decarbonise the value chain. Our reported Scope 1 and Scope 2 greenhouse gas (GHG) emissions for FY23 were 21.0 Mt CO2-e, a 0.2 per cent increase from FY22. Direct emissions from activities at our operations (Scope 1) increased by 0.5 Mt CO2-e, while there was a decrease of 0.4 Mt CO2-e in emissions from electricity used by our operations (Scope 2). We published our first Climate Change Action Plan in September 2022 and have made progress against key elements of the Plan in FY23, including updating our 1.5°C scenario to stress-test the potential impacts of climate change on our business. We commenced the conversion of Worsley Alumina’s first coal- fired boiler to natural gas and progressed decarbonisation studies including mud washing and waste heat to digestion. At Illawarra Metallurgical Coal we progressed a feasibility study into the commercial scale pilot of CSIRO ventilation air methane technology. For Hillside Aluminium, while our studies have confirmed the challenges associated with developing renewable and low-carbon energy sources in South Africa, we continue to investigate a range of potential solutions. We are studying options to acquire energy attributes to reduce the GHG intensity of its product in the near-term, while we pursue other low-carbon energy solutions for the longer term. At Mozal Aluminium, we are working with key stakeholders to extend the supply of hydro-electric power beyond 2026 and continue to investigate additional emissions reduction projects and technologies. Learn more about how we seek to deliver value to society, operate ethically and responsibly, manage our environmental impact and address climate change in our Sustainable Development Report at www.south32.net.

The Enterprise Development component, which was US$5.2 million in FY23, is captured in both the ESD total and the social investment total. (3) Represents the proportion of land disturbed by South32 which has since been rehabilitated. 24 OPERATING AND FINANCIAL REVIEW Sustainably reshape our business for the future IDENTIFY OPPORTUNITIES Our FY23 commitments: 〉 Develop and pursue opportunities to optimise our portfolio. Progress during the year: The substantial changes we made to our portfolio in FY22 to increase our exposure to the commodities critical to a low- carbon future have more than doubled our low-carbon aluminium capacity and introduced copper to the portfolio. While we remain open to opportunities around the world, our next phase of growth is expected to come from our development options in North America. In addition to the Hermosa project, our portfolio in Alaska includes our 50 per cent interest in the Ambler Metals Joint Venture which holds two sizeable base metals deposits including copper, silver, lead, zinc and gold in the highly prospective Ambler mining district. The Ambler Metals Joint Venture is focused on consolidating geological knowledge and advancing engineering studies for the Arctic Deposit. We continue to invest to discover deposits to underpin our next generation of mines with over 25 base metals exploration prospects around the world(4). Consistent with this approach, during the period we exercised our earn-in right to acquire a controlling stake in the Chita Valley copper exploration project in the San Juan province of Argentina, a region which hosts several copper deposits along a highly prospective mineral belt. At our wholly owned Roosevelt Project in Alaska, which is located in the same mineral belt as the Ambler mining district, an expansive drilling program was commenced in 2023 targeting potential copper and zinc mineralisation. In July 2022 we completed the sale of a package of non-core development-stage base metals royalties for a sale price of up to US$200 million, a further step forward in unlocking latent value from our portfolio. Exploring Opportunities to Support Host Communities At the Roosevelt Project in northern Alaska, we are engaging with the Doyon Native Corporation and five tribal villages that live in relative proximity to our early-stage exploration activities. As part of this engagement, we sponsored the Koyukuk River Spring Carnival, held at the village of Allaket, in April 2023. A logistical challenge given the remote location, the sponsorship included funding a fixed wing charter flight to transport a dog sled team to compete in the main event. The carnival was an opportunity for people to come together, particularly after restrictions imposed by the COVID-19 pandemic. In addition to the fiercely competitive dog sled and snowshoe races, younger generations were exposed to the traditions and cultural heritage of their elders and ancestors, a key aspect for the long-term sustainability of these communities.

Strong production growth in aluminium, base metals and manganese reflecting recent portfolio improvements and three annual production records. Measures our approach to investing in safe and reliable operations, improvements and life extensions, and growth options. We increased our investment in productivity, improvement and growth activities across our portfolio, including at the Hermosa project and reflecting the inclusion of Sierra Gorda. Underlying measures of earnings are important when assessing underlying financial and operating performance. Production growth, coupled with our continued focus on cost efficiencies, supported one of our largest underlying financial results despite lower commodity prices and inflationary pressures. Cash flow measures are important when assessing underlying financial and operating performance. Lower free cash flow reflects higher capital expenditure and one-off tax payments in relation to our Sierra Gorda acquisition and non-core royalty sale. Provides an indicator for shareholders of how well their investment is performing. We delivered record returns to shareholders during FY23 via ordinary and special dividends and our on-market share buy-back. (1) Copper equivalent production was calculated using FY22 realised prices, and includes operated and non-operated operations. (2) Includes intangibles and capitalised exploration expenditure, and material equity accounted investments on a proportional consolidation basis. (3) This is a non-IFRS measure. For an explanation of how South32 uses non-IFRS measures, see page 38. (4) Fully-franked ordinary and special dividends paid in respect of H2 FY22 (US$784M), fully-franked ordinary dividends paid in respect of H1 FY23 (US$223M) and on-market share buy-back (US$218M). 26 OPERATING AND FINANCIAL REVIEW KEY Strategy pillar Sustainability pillar Strategic risks Remuneration SUSTAINABILITY Health and safety Lost Time Injury Frequency (per million hours worked)(5) 1.4 FY22: 2.0 FY21: 1.7 People Employee engagement (per cent) 79 FY22: 78 FY21: - (survey did not take place due to the impact of COVID-19) Community Social investment (US$M)(6) 27.7 FY22: 31.1 FY21: 22.2 Environment Water use efficiency (per cent)(7) 61.5 FY22: 66 FY21: 56 Climate change Operational greenhouse gas emissions (Mt CO2-e)(8) 21.0 FY22: 21.0 FY21: 20.7(9) Why it matters Performance in FY23 Nothing is more important than the health, safety and wellbeing of our people. LTIF reduced by 30 per cent compared to the FY22 baseline, reflecting a reduction in the frequency of severe events. Engaging directly with our people allows us to understand how they experience all aspects of South32 and identify areas for improvement. Our employee engagement score, as measured in our Your Voice employee survey, improved by one per cent year-on-year. We invest in local communities with the aim of contributing to their social, economic, and institutional development. Social investment decreased by 11 per cent year-on-year, primarily due to social investment at Hillside Aluminium which is price-linked under South African legislation. Water is a valuable resource that we all share and a critical input for our operations. Water use efficiency decreased by four per cent due to challenges faced at operations such as above average rainfall and management of excess water. Human activity is causing climate change and the impacts are affecting ecosystems, biodiversity, and communities around the world. Our reported Scope 1 and Scope 2 greenhouse gas emissions increased by 0.2 per cent year- on-year, with Scope 1 emissions increasing by 0.5 Mt CO2-e and Scope 2 emissions decreasing by 0.4 Mt CO2-e. (5) Incidents are included where South32 controls the work location or controls the work activity. Lost time injuries include injuries that result in one or more lost work days after the day of the event. (6) Our total social investment comprised US$24.6M in direct investment (including Enterprise Development), US$2.5M in administrative costs, and US$0.6M of in-kind support. (7) Water use efficiency is calculated as the total recycling and reuse divided by the sum of total recycling and reuse and total operational inputs/withdrawal. (8) Includes Scope 1 and Scope 2 greenhouse gas emissions. (9) The FY21 baseline has been adjusted to exclude emissions from SAEC and TEMCO, which were divested in FY21. 27 SOUTH32 ANNUAL REPORT 2023 RISK MANAGEMENT MANAGING OUR RISKS TO PROTECT AND UNLOCK VALUE Risk management is fundamental to maximising the value of our business and informing its strategic direction. Effective risk management enables us to identify priorities, allocate resources, demonstrate due diligence in discharging legal and regulatory obligations, and meet the standards and expectations of our stakeholders. Our approach to risk management is governed by our risk management framework. Our internal risk management standard outlines the minimum mandatory requirements for the management of risks that can materially impact our ability to achieve our purpose, strategy and business plans. The framework and standard are delivered through our system of risk management which is aligned to the principles of the International Standard for Risk Management AS/NZS ISO 31000:2018. Our approach to risk management applies to all employees, directors and contractors of South32. Our risks are regularly assessed and managed at both a company-wide strategic level and at a tactical level for operation, project and function risks. Risk appetite  Risk appetite is the level of residual risk that we are willing to take in pursuit of our strategic objectives, which is established in relation to our operating environment. Our Board considers and approves the risk appetite developed by management. Our internal Risk Appetite Statements outline the extent to which we are or are not willing to engage with higher levels of risk (both threats and opportunities) in order to realise greater benefit in the pursuit of our purpose and strategy and in alignment with our values and Code of Business Conduct. Key risk indicators (KRIs) are set by management and used to monitor performance against our set risk appetite. Understanding our risk appetite across our strategic risks assists in decision- making across the Group. Material risks  Strategic risks  Our strategic risks are risks which can affect our ability to achieve our strategic objectives. They have the capacity to affect all, or a significant part, of our organisation and therefore tend to have significant impacts, both negative and positive. With that in mind, our strategic risks, associated KRIs and management responses are monitored and evaluated twice per year. The review process is informed by external and internal events that could have a potential impact on our organisation, as well as emerging themes across our material risks. In FY23, we identified 13 strategic risks which could influence our plans and the sustainability of our business, each of which is explained further in subsequent pages.   Strategic risk key The inherent risk impact or likelihood has increased over the past 12 months (i.e. without considering internal controls or management responses). The inherent risk impact or likelihood has remained constant over the past 12 months (i.e. without considering internal controls or management responses). The inherent risk impact or likelihood has decreased over the past 12 months (i.e. without considering internal controls or management responses). We apply the three lines operating model to our system of risk management, which determines how our structures, processes, and organisational roles work together to facilitate strong risk management and assurance. This approach is used to manage our material risks and enables us to: – Provide stable and consistent processes, tools and routines to identify and regularly assess the most impactful threats and opportunities; – Deliver predictable outcomes and prevent unforeseen events with material impacts; – Understand our risks and manage these at all levels of the organisation; and – Reduce or seek to eliminate risks where appropriate or improve our processes using a risk-based approach. Our material risks are those which can materially impact our ability to achieve our purpose, strategy and business plans. The effective management of our material risks is routinely assessed by our Lead Team. An overview of these risks are reviewed by our Risk and Audit Committee and Sustainability Committee, which assist our Board to carry out its role of overseeing our risk management and assurance practices. We report transparent real-time risk data through our risk management tool, Global360. This software connects data relating to the management of our risks, events, hazards and assurance actions. Aside from helping us manage our business, reliable data on material risks contributes towards the monitoring and management of our strategic risks. This provides insight into trends and emerging themes that can trigger a review of our business plans or inform a change in strategic direction. 28 OPERATING AND FINANCIAL REVIEW Keeping our people safe and well Portfolio reshaping A safe and healthy working environment is fundamental to living our values. Risk exposure trend 2023 Risk appetite Aligned to our purpose and values, we will not take actions that compromise the health, safety or wellbeing of our people, contractors and communities. Opportunities Keeping our people safe and well underpins the culture we aspire to and sets our expectations of each other. Threats The impact of not having a safe working environment can be devastating for our employees, contractors and communities. It can alter lives and impact shareholder returns, stakeholder confidence and ultimately our licence to operate. Our response includes: – In everything we do, we focus on the health, safety and wellbeing of our people, contractors and communities; – We have a system of risk management and comprehensive internal health and safety policies, standards and systems with associated performance requirements designed to prevent and mitigate potential exposure to health and safety risks; – We value and strive to build inclusion and diversity in our workplace where everyone is valued and can participate to achieve their full potential. We do not tolerate any form of inappropriate conduct which includes bullying, harassment, discrimination or victimisation; – We engage, develop and train our people so that our work is well designed and executed; – We investigate actual and potential significant events that could have led to severe injury or higher outcomes, put controls in place and share the learnings across our organisation; – We continuously improve our work environment with the aim of making it safer, healthier and more productive for our people. We are implementing our multi-year Group-wide Safety Improvement Program designed with the aim of enhancing our safety culture and by changing mindsets and behaviours, achieving a step change in our safety performance; and – In line with the three lines operating model, we have assurance functions independent of our operating activities that provide assurance against our own comprehensive internal standards. + Learn more about our approach to health and safety in our Sustainable Development Report at www.south32.net. Our objective is to improve our return on invested capital and create shareholder value by increasing our exposure to high-quality operations in commodities with a strong and sustainable outlook, in jurisdictions where we believe we can operate in line with our values and Code of Business Conduct. Risk exposure trend 2023 Risk appetite We accept that in actively transforming our portfolio, we need to take risk to capture opportunities. We will seek to do so in jurisdictions and commodities where we believe we can operate or invest in line with our values and Code of Business Conduct. Opportunities Increasing our exposure to the commodities critical to a low- carbon future will position our business for a low-carbon world, in alignment with our strategy. Acquisitions of operations or development options (including non-operating and non- controlling shares in these operations and development options) present us with opportunities to create shareholder value through increasing our exposure to these commodities. Partnering with junior explorers also creates opportunities for us in early-stage exploration in more challenging jurisdictions. Threats Changing global sentiment presents a threat to the sustainability of our current portfolio mix if we do not act to reshape our portfolio. In responding to stakeholder expectations, we could make decisions to dispose of climate or carbon exposed operations, development options and investments at less than market value. Increasing demand for the commodities critical to a low-carbon future may drive higher valuations of operations and development options that we want to acquire, making acquisitions challenging and potentially value destructive. A scarcity of attractive opportunities or a reliance on exploration to fill our pipeline of opportunities may impact the pace of transition. Geopolitical developments may also limit those jurisdictions in which we can operate or those counterparties with which we can partner or transact. Our response includes: – We are actively reshaping our portfolio towards commodities critical to a low-carbon future; – We take more risk on early-stage exploration projects, including jurisdictional risk as well as through joint ventures and earn-ins, but commensurate with the commercial exposure; – We will be flexible on opportunistic acquisitions including non- controlling and non-operating shareholdings in incorporated or unincorporated joint ventures; and – We carry out an annual review of commodity prices and exchange rates, to develop long-term views for our portfolio commodities and foreign exchange rates for the jurisdictions where we operate. This process is supplemented by tri-annual updates. + Learn more about how we are reshaping our portfolio in Our strategy in action on page 25. 29 SOUTH32 ANNUAL REPORT 2023 RISK MANAGEMENT CONTINUED Climate change and environment Climate change poses physical risks to our business, our people and the infrastructure, communities and environment on which we rely. The political, social and economic responses to the challenges posed by climate change and the transition to a low- carbon economy also pose risks to our business performance (i.e. demand for some of our commodities, cost and profit margins, social licence, regulatory exposure). Learn more about our approach to climate change, including our detailed assessment of the risks climate change poses to our business, in the Addressing Climate Change section of our Sustainable Development Report and our Climate Change Action Plan (CCAP), both of which available at www.south32.net. Our operations also have the potential to impact biodiversity, air, land and water resources. This may result in increased costs to mitigate or address such impacts, prevent or delay project approvals, and result in reputational damage. Water is critical to our operations and water scarcity, increased competition for supply or costs to access can impact our operations, supply chains and communities. Risk exposure trend 2023 Risk appetite We recognise the impact our operations have on the environment due to the extractive nature of our activities and that the greenhouse gas emissions associated with our activities contribute to climate change. We also recognise the role our industry plays in providing the materials that are essential in the transition to a net zero global economy and we want to be part of that solution. We acknowledge that we have potential vulnerabilities to the physical impacts of climate change and exposure to climate-related transition risk and nature-related risk. We accept that we need to take risks in order to minimise our environmental impact and reduce our exposure to physical and transition climate change risk and nature-related risk. We seek to take risks that may arise as we transform our portfolio to maintain competitiveness in a low-carbon world and pursue our greenhouse gas emissions reduction target and goals. Opportunities Aligning our business strategy, including how we operate and what we produce, with stakeholder expectations, future technologies and evolving climate and environmental policies and regulations, contributes to a resilient and high performing portfolio. We aim to increase the efficiency of our operations and support business continuity through responsibly assessing and addressing our climate change and environment-related risks, dependencies and impacts, and increasing the resilience of our business, the value chain and communities in which we operate. Threats The complex and pervasive nature of climate change means that climate-related risks and opportunities are reflected across our risk profile. For further details on the potential impacts of climate change on our strategic risks, refer to the Addressing Climate Change section of our Sustainable Development Report and pages 99 to 101 of our CCAP. Failure to manage environmental and climate-related risks may impact our ability to secure development approvals, permits or licences and increase our legal exposures. It may also limit our ability to access capital and insurances, develop strategic partnerships with Indigenous, Traditional and Tribal Peoples or environmental organisations, attract and retain employees, deliver our project portfolio, and grow our business in existing and new jurisdictions. Our response includes: – Our approach to managing the transition and physical risks of climate change is outlined in the Addressing Climate Change section of our Sustainable Development Report and our CCAP; – Our sustainability approach, inclusive of our environmental performance requirements, is guided by the ICMM Mining Principles, United Nations Global Compact (UNGC) Ten Principles and United Nations Sustainable Development Goals and is outlined in our Sustainability Policy and Sustainable Development Report at www.south32.net; – We seek to manage water resources using a holistic approach to promote better water use, effective catchment management and to contribute to improved water security and sanitation; – We establish contextual water targets for operations exposed to water-related material risks with consideration for broader stakeholder and catchment needs; – Our operations address biodiversity impacts with a focus on minimising our operational impacts through application of the biodiversity mitigation hierarchy and collaborating with others to contribute towards biodiversity conservation and restoration; – We aim to achieve no net loss outcomes for all new projects and major expansions to existing projects through a balanced application of the biodiversity mitigation hierarchy of avoidance, minimisation, rehabilitation and offsetting; – We integrate land management and rehabilitation processes into our business planning and give consideration to cumulative impacts when developing management controls to minimise impacts on surrounding ecosystems; – We manage our waste streams to minimise environmental impact and realise value through a balanced application of the waste mitigation hierarchy of prevention, minimisation, reuse, recycle, recovery and disposal; – We engage regularly with investors, governments, industry partners, membership-based sustainability organisations, environmental, social, and governance (ESG) proxy advisers and ESG activist groups to identify and monitor emerging environmental and climate change risks, opportunities and trends; and – We are transparent in our disclosure of environment and climate-related opportunities and threats in our annual reporting, in accordance with the Global Reporting Initiative (GRI) Sustainability Reporting Standards and recommendations of the Task Force on Climate-related Financial Disclosures. + Learn more about how we are addressing climate change and managing our environmental impact in our Sustainable Development Report at www.south32.net. 30 OPERATING AND FINANCIAL REVIEW Maintain, realise or enhance the value of our Mineral Resources and Ore Reserves We intend to realise the potential of the resources and reserves we are entrusted to develop. We work to continually optimise our operations through sound technical and economic understanding of our resources and reserves. Major external events or natural catastrophes Our operations and logistics networks can be disrupted by events such as pandemics, natural disasters and extreme weather events that could impact people’s safety, wellbeing, security, the integrity of tailings storage facilities and key operating infrastructure. Risk exposure trend 2023 Risk exposure trend 2023 Risk appetite We are not willing to take risks that inhibit our ability to realise the potential of the resources and reserves we are entrusted to develop. Opportunities We continue to enhance our understanding of our resources and reserves. We leverage this enhanced understanding through the annual planning cycle to define and assess additional opportunities to add value to our business. Threats If we fail to continually optimise our operations and projects, it will have a significant impact on future shareholder returns, the benefits our stakeholders receive and ultimately, the sustainability of the company Our response includes: – We have capital prioritisation, capital allocation and planning processes which prioritise the highest-value options across our portfolio; – We apply an annual planning process that considers the impact of climate change on our Ore Reserves, with plans structured to maximise value throughout the life of our operations; – Drill plans and budgets are approved as part of our annual planning cycle and compliance to those plans is reported monthly. Where there is material deviation to plan, actions are taken to reduce deviation; – We apply a rigorous project development process that includes independent peer review of project risks and approval tollgates; – We report Mineral Resources and Ore Reserves (including Coal Resources and Coal Reserves) in accordance with the JORC Code as required in the ASX Listing Rules (Chapter 5); and – We have an internal closure standard which requires that the full life of operation value incorporates closure and rehabilitation liabilities. + Learn more about resources and reserves (including governance processes) on pages 169 to 176. Risk appetite We are not willing to take risks that compromise our ability to manage natural catastrophes. However, we accept we operate in a diverse range of geographic locations, which are exposed to natural events and other external events. Opportunities Achieving stable and predictable performance enhances the value proposition to our shareholders, stakeholders and the communities in which we operate. The better we prepare for and learn from events, the better we are placed to respond and aim to reduce the impact of future events – strengthening our organisational resilience. Threats Failure to manage major events or natural catastrophes could result in a significant event or other long-term damage that could harm the company’s access to logistics chains and critical goods and services, financial performance, and licence to operate. The role of climate change in increasing the frequency and severity of natural catastrophes is addressed under ‘Climate change and environment’ on page 30. Our response includes: – When facing potential catastrophes, we put safety and wellbeing at the heart of everything we do; – We use our system of risk management in design, construction and operation phases to analyse risks, and design and implement actions that aim to prevent or limit business impacts; – We utilise climate modelling data to inform our long-term plans and project pipelines, and conduct physical risk assessments of our assets every two years; – We have business continuity and disaster response plans in place with trigger action response scenarios. We have tested these to make sure we can respond rapidly to major events and safely restore our operations, aiming to protect the health and safety of our people and the communities in which we operate; – Consistent with the three lines operating model, we have assurance functions independent of our operating activities that provide assurance against our own comprehensive internal standards including equipment integrity, tailings management and technical stewardship. Where relevant, we work with external experts, relevant industry bodies and technology suppliers, to provide additional assurance and input; and – We purchase insurance coverage against many, but not all, potential losses or liabilities arising from major events or natural catastrophes. This coverage has a deductible cost to the company and limits that mean full financial coverage cannot be achieved. 31 SOUTH32 ANNUAL REPORT 2023 RISK MANAGEMENT CONTINUED Maintain competitiveness through technology and innovation Technology and innovation are advancing at a rapid pace. Companies which are unable to effectively leverage technology and innovation may find themselves failing to deliver against shareholder expectations on returns, unable to attract and retain talent or, in the example of decarbonisation, failing to maintain licence to operate. The use of ransomware is becoming more prevalent in cybersecurity incidents across the mining industry. Our response includes: – We have a clearly defined approach to innovation, improvement and technology; – We deliver specific programs focused on adoption and improvement of critical technology capabilities across multiple time horizons; – We have a value-based ‘portfolio’ approach to testing and scaling up innovation across the company; – We have rigorous internal technology standards and processes (technology ‘ways of working’); – We benchmark our digital technology performance against industry best practice and coordinate and integrate technology advances into our growth portfolio; – We actively manage cybersecurity and loss of critical systems risks through our system of risk management; and – We monitor internal customer satisfaction and manage customer support. + Learn more about how technology and innovation are unlocking value in Our strategy in action on page 22. Risk exposure trend 2023 Risk appetite We are not willing to take risks that will result in a loss of data or disruptions to our operations and projects due to the theft, disclosure or corruption of information. Aligned to our strategy, we will pursue technology and innovation that may have a lower certainty of success where there is commensurate potential for high return on investment. Opportunities To stay competitive, we position our organisation to effectively identify, develop and adopt sustainable business models for technology and innovation in our operations and projects. Priority innovation opportunities are identified and delivered through Innovate32, our strategy-aligned, value-focused, innovation portfolio. This approach will assist us to deliver on shareholder return expectations and position us for future business opportunities. Threats Failure to keep pace with, and leverage advances in, technology and innovation could result in reduced shareholder returns and impact our licence to operate. Failure to adopt automation, electrification and digital systems could result in deteriorating performance across safety, productivity, returns and greenhouse gas emissions. Cybersecurity incidents could pose multiple risks including disruption to new projects and operations, theft, disclosure or corruption of information. 32 OPERATING AND FINANCIAL REVIEW Predictable operational performance Delivery of our project portfolio Loss of predictable operational performance will prevent us from reliably delivering on our strategic objectives. We build resilience and predictability into our business by sustaining our ability to keep our people safe and well, meeting our regulatory and social obligations, managing cost inflation and consistently providing quality products to our customers. Risk exposure trend 2023 Delivery of our project portfolio, both brownfield and greenfield, forms a critical component of our strategy. Delivery of projects safely, on schedule and within budget allows us to optimise and unlock the value of our business. Risk exposure trend 2023 Risk appetite We are not willing to take risks that compromise the stable and predictable performance of our operations.    Opportunities We mature our Operating System to control and continuously improve our operations and processes, so that we can deliver stable and predictable performance and unlock the full value of our business. We invest in our operations to sustain and improve production capacity that generates reliable cash flow to deliver on our strategic objectives. Threats External volatility and challenges can impact predictable performance. These include labour and supply chain tightness as well as regulatory and geopolitical change. If we are unable to safely and consistently achieve our production, cash flow or profitability targets, it could negatively impact our ability to deliver on our strategic objectives and negatively impact shareholder returns. Our response includes: – We have embedded, and continuously verify and improve our safety and risk management systems across our business; – We have an effective asset management system in place at each operation and review our asset health, asset integrity and capital investments on a regular basis; – We actively verify and improve the effectiveness of our Operating System by embedding our operating practices including operational planning, work design and standards, process control and improvement; – We actively manage risks to our resources and reserves, mine and operational planning including reconciliation of Ore Reserves to production, plan and spatial compliance and management of geotechnical risks; – We manage an integrated system of long to short-term planning and scheduling processes that considers ESG themes and optimises the value from our resources; – We actively manage product delivery and supply chain risks including effective sales and operational planning processes, monitoring of raw material supply and management of target inventory operating windows; and – We carry out quality assurance programs over our products and operations. Risk appetite Aligned to our strategy of unlocking value in our business, we will not take actions that compromise the planning and execution of our major projects. However, we may accept greater levels of risk to pursue opportunities to extend the life of existing operations through brownfield projects and in executing decarbonisation projects for our assets. Opportunities Delivery of our project portfolio on time and within budget allows us to improve reliability, complement our existing assets, extend the life of our operations, realise our external commitments and grow volumes into structurally attractive markets. Threats Inability to deliver the project pipeline may impact on our future cash flows, reputation and return on investments. Known and emerging uncertainties that may challenge the timely and successful execution of our projects can include satisfying conditions for regulatory approvals, permitting delays, supply chain disruptions, high inflation, joint venture partner misalignment, and activism. Our response includes: – A comprehensive and adaptable project management framework supports disciplined project development and execution to realise the value of opportunities while mitigating the risk of suboptimal outcomes; – We continue to develop our Operating System for major projects, and mature our performance in delivering projects on cost and on schedule; – Our joint venture agreements include mechanisms such as technical committees and independent peer reviews to influence project, schedule, and cost outcomes; – We apply a standardised valuation methodology with consistent key macroeconomic assumptions; – We maintain a life of operation annual planning process. By evaluating the embedded project options in our operations, we look to optimise value throughout the life of our operations; – We conduct an annual review of commodity prices and exchange rates which informs our project budgets. This process is supplemented by tri-annual updates; and – Our internal investment framework defines a disciplined tollgate process with a mature and independent peer review mechanism which we rigorously follow to inform key investment decisions. + Learn more about our operational performance in Our strategy in action on page 21. + Learn more about our project execution in Our strategy in action on page 23. 33 SOUTH32 ANNUAL REPORT 2023 RISK MANAGEMENT CONTINUED Security of supply of logistics chains, and critical goods and services The inability to secure supply of critical goods and services, such as raw materials, energy, water, gas, equipment and spare parts, consumables, technology, corporate services, labour and logistics (which includes road, rail and shipping), has the potential to impact business performance and our strategic objectives. The procurement of critical goods and services must be undertaken in a manner that aligns to our purpose and values, meets stakeholder expectations and adheres to the policies and regulations where we operate. This includes sustainable sourcing and supporting local communities. The security of our supply chain is heavily impacted by pandemics, jurisdictional unrest, geopolitical tensions and a shift from globalism towards protectionism. Risk exposure trend 2023 Risk appetite Aligned to our strategy of optimising our business, we are not willing to take undue risks that compromise the security of our supply chain logistics and critical services. However, we accept that we have a strong reliance on certain critical suppliers, particularly to provide energy, logistics, and raw materials to our operations and we have limited ability to reduce this reliance. Opportunities Optimal and sustainable management of supply chain risk positions our business to operate safely and reliably, at the lowest possible cost and in a manner that meets or exceeds the expectations of our stakeholders. It also provides us with the ability to influence how others in our industry approach sustainable sourcing and to position us to benefit as trade flows respond to rising protectionism, social consciousness and general trends to de-risk value chains. Threats Disruption of our supply chain could materially impact our ability to deliver on our commitments and meet the expectations of our stakeholders. Failure to meet minimum ethical supply chain standards has the potential to damage our social licence to operate (this is further addressed under ‘Evolving societal expectations’ on page 36). Climate change has the potential to increase the frequency and severity of extreme weather events which may threaten our supply chains, particularly logistics and the availability of critical goods and services (this is addressed under ‘Climate change and environment’ on page 30, and in the Addressing Climate Change section of our Sustainable Development Report). Our response includes: – We understand, assess and continually monitor the risks in our supply chains through an integrated system that considers the supply of critical goods and services. This includes risks relating to potential shortages, critical suppliers and categories, vendor liquidity, logistics, climate change and decarbonisation, and modern slavery; – Internal and external data is integrated so we have a good understanding of existing and emerging risks and can take action to mitigate; – We use this understanding of risk to deploy controls to support predictable operations. This includes working closely with our vendors and operations to match availability with demand; understanding options for alternative sources of supply and implementing multi-source supply where required; optimising inventory levels; flexing commercial terms and maintaining up-to-date business continuity plans. We continually optimise our approach between ‘just in case’ and ‘just in time’ as supply chain risk ebbs and flows; – We build strong strategic partnerships with key suppliers on a long-term, mutually beneficial basis; – We have a clearly defined transformation strategy and Enterprise Supplier Development program in South Africa aimed at building and growing small, medium and micro enterprises; – We have Reconciliation Action Plan targets to develop and support Aboriginal and Torres Strait Islander enterprises in Australia; – We have local procurement initiatives designed to increase opportunities for local suppliers; – We actively review and manage payment terms to support small and local businesses in all jurisdictions in which we operate; and – We have an established process to assess and mitigate potential modern slavery risks. + Learn more about our responsible value chain activities in our Sustainable Development Report at www.south32.net. 34 OPERATING AND FINANCIAL REVIEW Shaping our culture and managing diverse talent We must actively shape and embed our culture to attract, develop, support, and retain our talented people to deliver safe, predictable performance and continuously improve. To align with the evolving needs of our people, business and broader stakeholders, we continuously monitor our culture and seek feedback to enhance the employee experience. Risk exposure trend 2023 Risk appetite People underpin everything we do and we are not willing to take risks that could negatively impact our culture and the way our people connect to our purpose. However, we recognise our size and the competitive labour market in which we operate and therefore must be willing to take risk to build our talent and succession pipeline.   Opportunities By shaping and embedding our aspired culture through our systems, symbols and behaviours, we will create an employee experience that engages all our people to better deliver our strategic objectives, together. Threats If we are unable to embed our preferred culture, we will likely have lower levels of engagement, disconnected teams that lack diversity and operate in silos, and relationship rather than performance-based decision making. Over time, this may constrain innovative thinking and impact our ability to attract and retain talent, which may lead to significant shareholder value erosion and reputational damage. Our response includes: – Our Code of Business Conduct sets out our expected standards of conduct, with formal training and assessment routines in place. Anyone can report a business conduct concern, anonymously if preferred, or by using our confidential and independently administered reporting hotline; – We measure and discuss culture using a Culture Tensions framing model.

In order to keep pace with these rapidly evolving expectations and understand the potential impact to our business performance, reputation and delivery of our strategic objectives, we maintain an active stakeholder engagement program and undertake external monitoring on a wide range of financial and ESG issues, including climate change. We regularly engage with our stakeholders to understand and respond to their views, which may be divergent, and aim to identify ways we can create enduring social, environmental and economic value, in a way that aligns with our purpose and values. Risk exposure trend 2023 Risk appetite We are not willing to take risks that will result in a failure to meet societal expectations, in human rights, cultural heritage, modern slavery and community safety. However, we accept that we will be required to take some risks in areas such as impacts of mining (e.g. on the environment) and commodity selection that may not completely align with societal expectations. Opportunities Proactive, collaborative and transparent engagement with our stakeholders builds relationships based on trust and shared understanding. Our ongoing licence to operate is built on our contribution to our stakeholders and broader society. Threats Failure to meet evolving societal expectations for ESG performance could damage our reputation and negatively impact our licence to operate, limiting our ability to access capital or markets, retain and attract employees and grow our business in existing and new jurisdictions. Our response includes: – Our purpose and strategy expressly balance economic outcomes with social and environmental outcomes, now and into the future. In the decisions we take, we look to minimise impact, respect human rights and aim to create enduring social, environmental and economic value for all our stakeholders, in a way that aligns with our purpose and values; – We undertake internal and external stakeholder analysis and engagement on a wide range of financial and ESG issues, including an annual materiality process to understand our material ESG issues. Our approach is aligned with the ICMM Mining Principles, The UNGC Ten Principles and GRI Sustainability Reporting Standards; – We engage with our customers to understand their requirements and drivers for responsible production, sourcing and stewardship in the supply chain. We work with certification bodies such as the Aluminium Stewardship Initiative to seek certification against their performance standards to help facilitate continued access to markets; – We work to build strong, positive and meaningful relationships with local communities. We regularly complete and review community perception surveys, human rights impact assessments, social baseline studies and social impact and opportunity assessments to improve our understanding of the communities in which we operate; – We review and amend our social investment program annually to align with community and stakeholder priorities. We measure the outputs and outcomes of our social investments as it informs future investment decisions and improves social investment project design; – We develop economic development plans at all our operations which contribute to local and regional economic development through employment, procurement and business development. These plans include targets informed by local context, including women and people with diverse backgrounds; – We engage with Indigenous, Traditional and Tribal Peoples across our operations to build mutual understanding and strengthen cultural heritage management. Our engagement with Indigenous, Traditional and Tribal Peoples throughout the life of our operations is sensitive to and respects cultural protocols; and – We participate in sustainability reporting transparency initiatives and ESG rating agency reviews that assess and score our performance. + Learn more about how we are delivering value to society in our Sustainable Development Report at www.south32.net. 36 OPERATING AND FINANCIAL REVIEW Political risks, actions by governments and/or authorities Changes in legislation, regulation, policy and geopolitical activity have the potential to impact our strategic objectives and the way we work. This includes broader policy decisions and regulatory changes, related but not limited to, changes to royalty and taxation policy, nationalisation of mineral resources, supply chains, renegotiation or nullification of contracts, leases, permits or agreements, climate change and emissions reduction requirements and environmental and social performance requirements. We aim to effectively manage this uncertainty through engagement with key stakeholders and industry associations, monitoring of political activity, policy, legislative and regulatory changes, and by having access to specialised knowledge. Risk exposure trend 2023 Risk appetite We have a low appetite for activities that are likely to result in non-compliance with applicable legal or regulatory requirements. We maintain programs that seek to comply with those requirements. However, there can be no guarantee that such programs will always be effective to identify or prevent breaches of the law. Further, we operate in certain complex environments and jurisdictions, which are subject to legislative, regulatory or government policy changes that may adversely impact our business. Therefore, there will always be residual risk in relation to compliance with legal and regulatory requirements and changes to those requirements that may adversely impact our business. Opportunities Proactive engagement leading to strong relationships with governments and authorities provides a mutual understanding of drivers for decision making. This increases clarity around policy and regulatory environments, enables appropriate and tailored responses to issues and provides investment certainty. Threats Legislation adverse to our business and regulatory or policy decisions taken by governments or authorities, particularly relating to societal expectations, can result in operational disruption, permitting uncertainty, affect future planning or lead to cessation of operations or non-investment in operations or projects. Our response includes: – We have specialised knowledge through in-house expertise or the use of external experts, including tax management capability, tax advice and external affairs advice; – We monitor political activity, policy, and legislative and regulatory changes in the jurisdictions where we operate, and we also engage with relevant authorities, to understand and mitigate potential impacts on our business performance; – We engage with key stakeholders in all jurisdictions where we operate, in accordance with our stakeholder engagement plans; – We work through selected industry associations to influence how the industry is positioned; and – We produce an annual Tax Transparency and Payments to Governments Report, which shows how we meet our regulatory tax obligations. + Learn more about our approach to tax in our Tax Transparency and Payments to Government Report at www.south32.net. Global economic uncertainty and liquidity We prioritise an investment grade credit rating and a disciplined approach to allocating capital which aims to keeps our balance sheet strong, providing us with financial flexibility regardless of market conditions. By creating competition for capital and investing selectively in our existing operations, growth options and external opportunities, or by making returns to shareholders, we aim to maximise total shareholder returns over time. Risk exposure trend 2023 Risk appetite We are not willing to take risks that may limit our ability to maintain a minimum liquidity balance and/or access to funding on acceptable terms. We recognise our preferred commodity basket and our operating costs have the potential for price and exchange rate volatility outside of our control, and while we accept that as a resource company we are exposed to this inherent risk, we will act to reduce its impact by understanding its effect on our business.  Opportunities By investing selectively in our existing operations and growth options, external opportunities, or by making returns to shareholders, we aim to maximise total shareholder returns over time. Threats A significant or sharp deterioration in economic conditions can adversely impact market demand, commodity prices, and/or exchange rates which has the potential to significantly reduce profitability, cash flow and returns to shareholders. An increase in volatility, especially when it has an impact on in-bound and out-bound supply chains, has the potential to increase working capital requirements, affecting our liquidity. A reduction in liquidity available in capital markets has the potential to impact our balance sheet and ability to pursue our strategy. Our response includes: – We have a diverse portfolio of operations, commodities and end markets which strengthens our resilience to the disruption of any one commodity, geography or operation; – We prioritise a strong balance sheet and an investment grade credit rating, with the aim of remaining resilient through economic cycles; – We test our financial strength across a range of scenarios, including a depressed demand and pricing environment. We also maintain a minimum liquidity buffer and access to a diverse range of funding sources; – We adjust our capital allocation plans according to market conditions; – We maintain strong relationships with high-quality financial institutions, customers and suppliers from all around the world; – We mostly sell our products with reference to floating, market- based prices, which are broadly correlated with floating global currency markets and the input costs we are exposed to; and – We carry out an annual review of commodity prices and exchange rates, which informs our operational plans. This process is supplemented by tri-annual updates. + Learn more about our capital management framework in Our strategy on page 19. 37 SOUTH32 ANNUAL REPORT 2023 FINANCIAL AND OPERATIONAL PERFORMANCE SUMMARY STRONG GROWTH IN COMMODITIES CRITICAL FOR A LOW-CARBON FUTURE We increased our supply of commodities critical for a low-carbon future, recording strong production growth as we realised the benefit of recent portfolio improvements. In discussing the operating results of the Group, the focus is on Underlying earnings and ROIC. Underlying earnings is the key measure that is used by the Group to assess our performance, make decisions on the allocation of resources and assess senior management’s performance. In addition, the performance of each of the Group’s operations and operational management is assessed based on Underlying EBIT. Management uses this measure because financing structures and tax regimes differ across the Group’s operations and substantial components of tax and interest charges are levied at a Group level rather than an operational level. The Group uses both International Financial Reporting Standards (IFRS) and non-IFRS financial measures such as underlying measures of earnings, effective tax rate (ETR), return on invested capital (ROIC), cash flow and net cash/ (debt), to assess the Group’s performance. The Directors believe that the non-IFRS measures are important when assessing the underlying financial and operating performance of the Group and its operations. The meanings of individual non-IFRS measures used in this report are set out in the Glossary on page 181. The basis of the Group’s underlying financial results is included on page 113 in note 4 to the financial statements, which reflect the Group’s interest in material equity accounted joint ventures on a proportional consolidation basis. We believe that Underlying earnings before interest, tax, depreciation and amortisation (EBITDA), Underlying earnings before interest and tax (EBIT) and Underlying earnings provide useful information, but should not be considered as an indication of, or an alternative to, profit/(loss) after tax as an indicator of actual operating performance or as an alternative to cash flow as a measure of liquidity. In order to calculate Underlying EBITDA, Underlying EBIT and Underlying earnings, the following items are adjusted as applicable each period, irrespective of materiality: – Exchange rate (gains)/losses on restatement of monetary items; – Impairment losses/(reversals); – (Gains)/losses on disposal and consolidation of interests in operations; – (Gains)/losses on non-trading derivative instruments, contingent consideration and other investments measured at fair value through profit or loss; – Major corporate restructures; – Joint venture adjustments for material equity accounted investments; – Exchange rate variations on net cash/ (debt); – Tax effect of earnings adjustments; and – Exchange rate variations on tax balances. In addition, items that do not reflect the underlying operations of the Group, and are individually, or in combination with other related earnings adjustments, significant to the financial statements, are excluded to determine Underlying earnings. 38 OPERATING AND FINANCIAL REVIEW Financial key performance indicators for FY23 Financial highlights US$M Revenue Profit before tax and net finance income/(costs) Profit/(loss) after tax Basic earnings per share (US cents)(1) Ordinary dividends per share (US cents)(2) Special dividends per share (US cents) Other financial measures Underlying revenue(3) Underlying EBITDA Underlying EBITDA margin Underlying EBIT Underlying EBIT margin Underlying earnings Basic Underlying earnings per share (US cents)(1) ROIC Ordinary shares on issue (million) at the end of the reporting period FY23 7,429 198 (173) (3.8) 8.1 - 9,050 2,534 29.4% 1,616 18.7% 916 20.0 10.0% 4,545 FY22 9,269 3,724 2,669 57.4 22.7 3.0 10,630 4,755 47.1% 3,967 39.4% 2,602 56.0 33.0% 4,628 Change (20%) (95%) N/A N/A (64%) N/A (15%) (47%) (17.7%) (59%) (20.7%) (65%) (64%) (23.0%) (2%) (1) FY23 basic earnings per share is calculated as Profit/(loss) after tax divided by the weighted average number of shares for FY23 (4,572 million).

External factors and trends affecting the Group’s result The following describes the main external factors and trends that have had a material impact on the Group’s financial position and results of operations during the financial year. Details of the Group’s most significant risk factors (including environmental, social and governance risks), and how they are mitigated can be found in the Risk management section on pages 28 to 37. The Board and management monitor particular trends arising from external factors with a view to managing the potential impact on the Group’s future financial position and results of operations. Commodity prices and changes in product demand and supply South32 produces metals, concentrates and ores, for which prices are driven by global demand and supply for each of these commodities. Commodity prices were generally lower in FY23 compared to FY22 as most physical markets weakened on the back of global monetary tightening following the rise in inflation. The prices that the Group obtains for its products are a key driver of business performance, and fluctuations in these markets affect our results, including cash flows and shareholder returns.

(5) FastMarkets Manganese Ore 44 per cent Mn Cost, Insurance, and Freight (CIF) Tianjin China. The following summarises the pricing trends of our most significant commodities for FY23. The price change reflects the average of FY23 over FY22. Alumina: The average FOB Australia price for FY23 was 11 per cent lower than FY22 driven by the combination of weak aluminium demand, and supply capacity being added from alumina refinery expansions within China. Aluminium: The average LME cash settlement price for FY23 was 19 per cent lower than FY22. The price decrease was driven by subdued global demand, and lower cost of aluminium production stemming from falling energy costs, in some regions. Copper: The FY23 average LME cash settlement price was 14 per cent lower than FY22. The price decrease was underpinned by weak global demand and expected strong supply growth in the next few years. Silver: The FY23 average LBMA silver price was eight per cent lower than FY22. The price fall was underpinned by the rising interest rates which tempered investment appetite for silver. Weaker industrial activity globally, including in China, also impacted demand for silver as an industrial metal. Lead: The FY23 average LME cash settlement price was 10 per cent lower than FY22. Despite improved global automotive output, price declines were driven by an uncertain macroeconomic outlook and rising interest rates which impacted market sentiment and smelter restarts in the world ex-China, leading to higher refined lead availability. Zinc: The FY23 average LME cash settlement price was 15 per cent lower than FY22. Weaker global demand, including softer industrial activity in China and Europe led to a decline in prices amidst expectation of higher refined production as smelters restart in Europe. Nickel: The FY23 average LME cash settlement price was two per cent higher than FY22. Prices strengthened in the first half of FY23 due to trading activity and strong demand for nickel- in-batteries. In the second half of FY23, prices declined due to growing supply in Class I nickel (which contains a minimum of 99.8 per cent nickel), slower than expected demand recovery in Chinese stainless steel, and concerns over rapid new supply growth over the next few years. Metallurgical coal: The FY23 average Platts Premium Low-Vol Hard Coking Coal price was 28 per cent lower than FY22. Price declined as the market rebalanced due to improved seaborne supply, particularly from Australia in Q4 FY23 after the end of the La Niña weather impacts, while demand outlook weakened with Chinese steel demand recovery underperforming market expectations. Manganese ore: The FY23 average Manganese Ore Metal Bulletin 44 per cent Mn CIF China price was 16 per cent lower than FY22. Despite supply disruptions, weak global demand resulted in oversupply of ore and high Chinese port inventories, contributing to the price decline. 40 OPERATING AND FINANCIAL REVIEW Exchange rates Global risk sentiment, central bank monetary policy and commodity prices continue to be key drivers of currency markets. In FY23, producer currencies saw mixed results against the United States (US) dollar. The US dollar started to weaken in the second half of FY23 as various central banks were pushed into raising interest rates, reducing the rate differentials between the US and major economies. On average, the Brazilian real strengthened two per cent over FY23 on a record trade surplus and better economic outlook after the government published a new fiscal framework. The Australian dollar, South African rand, Colombian peso, and Chilean peso weakened against the US dollar over FY23 mainly driven by lower commodity prices which negatively impacted the countries’ export earnings and terms of trade. The Group is exposed to exchange rate risk on foreign currency sales, purchases and expenses, as no active currency hedging is undertaken. As the majority of sales are denominated in US dollars, and the US dollar plays a dominant role in the Group’s business, funds borrowed and held in US dollars provide a natural hedge to currency fluctuations. Operating costs and costs of locally-sourced equipment are influenced by fluctuations in local currencies, primarily the Australian dollar, South African rand, Brazilian real, Colombian peso, and Chilean peso. The Group is also exposed to exchange rate translation risk in relation to net monetary liabilities, being foreign currency denominated monetary assets and liabilities, including debt, tax and other long-term liabilities. Details of the exposure to foreign currency fluctuations are set out in note 19 to the financial statements on pages 142 to 149. The following table indicates the estimated impact on FY23 Underlying EBIT of a change in the significant currencies to which the Group is exposed against the US dollar. The sensitivities give the estimated impact on Underlying EBIT based on the exchange rate movement in isolation. The sensitivities assume all variables except for exchange rates remain constant. There is an inter-relationship between currencies and commodity prices where movements in exchange rates can cause movements in commodity prices and vice versa. This is not reflected in the sensitivities below. These sensitivities should therefore be used with care.

We increased our supply of commodities critical for a low-carbon future, recording strong production growth in aluminium (14 per cent), base metals (17 per cent), and manganese (four per cent), as we realised the benefit of recent portfolio improvements and achieved annual production records at Hillside Aluminium, Australia Manganese and South Africa Manganese. Underlying earnings were US$916 million, a decrease of US$1,686 million from FY22, as lower commodity prices, higher inflation and uncontrollable costs, more than offset higher production volumes at some of our operations. Underlying EBITDA decreased by US$2,221 million to US$2,534 million in FY23, for a Group operating margin of 29 per cent. This represented one of our largest Underlying EBITDA results, despite lower commodity prices and uncontrollable cost impacts. Our investments in Sierra Gorda and increased ownership in Mozal Aluminium contributed Underlying EBITDA of US$240 million. Free cash flow from operations, including equity accounted investment distributions, was US$244 million, impacted by a build in inventories and one-off cash tax payments in relation to our Sierra Gorda acquisition and non-core royalty sale. We returned a record US$1,225 million to shareholders during FY23, with US$1,007 million in fully-franked ordinary and special dividends, and US$218 million via our on-market share buy-back. We have announced a fully-franked final ordinary dividend of US$145 million (US 3.2 cents per share) in respect of H2 FY23, and expanded our capital management program by US$50 million leaving US$133 million to be returned by 1 March 2024, reflective of our disciplined approach to capital management. We continue to prioritise a strong balance sheet and investment grade credit rating through all cycles. We finished the period with net debt of US$483 million, following the return of record amounts to shareholders and our investments to grow production volumes of commodities critical for a low-carbon future. This strong platform and our disciplined approach to capital management provides us with the flexibility to continue to return capital to shareholders in the most efficient and value accretive manner, while investing in our growth options. Specific highlights for FY23 included: – Record annual production at three operations; – Embedded portfolio improvements in copper and low-carbon aluminium; – Fifteen per cent production growth in aluminium and base metals; – Record US$1.2 billion returned to shareholders, equivalent to 11 per cent of our current market capitalisation; – Advanced our portfolio of high-quality growth options, progressing work to support planned investment decisions for the development of Hermosa’s Taylor zinc-lead-silver Deposit and the Sierra Gorda copper expansion in FY24; – Confirmed the opportunity to produce battery-grade manganese from Hermosa’s Clark Deposit and signed multiple non-binding, non-exclusive memorandums of understanding for future potential supply into North American markets; – Consolidated our position in San Juan, Argentina, exercised our earn-in right for a 50.1 per cent interest in the Chita Valley copper prospect and acquired a strategic interest in Aldebaran Resources Inc; – Advanced near-term decarbonisation programs to support our target to halve operational greenhouse gas (GHG) emissions by 2035 from an FY21 baseline(1), with Worsley Alumina on- track to convert its first onsite boiler from coal to natural gas in Q1 FY24; – Transitioned Sierra Gorda to cost efficient, 100 per cent renewable electricity supply from January 2023; and – Progressed partnerships to address value chain emissions and expanded our climate change goals to include net zero Scope 3 GHG emissions by 2050.

Consistent with our accounting policies, various items are excluded from the Group’s statutory profit/(loss) to derive Underlying earnings. Total adjustments to derive Underlying EBIT (US$1,418 million), include: – Net impairment loss of non-financial assets (+US$1,300 million): non-cash impairment expense of Hermosa’s Taylor Deposit, as announced on 24 July 2023. The impairment reflected the impact of delays due to COVID-19, significant dewatering requirements, and current inflationary pressures; – Significant items (-US$186 million): gain on disposal of non-core base metal royalties to Ecora Resources PLC (-US$189 million pre- tax) and recognition of other income in relation to the indemnity for Chilean mining tax changes negotiated as part of our acquisition of Sierra Gorda (-US$48 million pre-tax), partially offset by a non-cash asset write-off following our decision not to proceed with the Dendrobium Next Domain (DND) project at Illawarra Metallurgical Coal (+US$51 million pre-tax); – Sierra Gorda (+US$144 million) and Manganese (+US$147 million) joint venture adjustments: adjustments to reconcile the statutory equity accounting position to a proportional consolidation basis; and – Net impairment loss of financial assets (+US$71 million): periodic revaluation of the shareholder loan receivable from Sierra Gorda reflecting copper price and other macroeconomic assumptions. An offsetting amount is recorded in the Sierra Gorda joint venture adjustments noted above. Further information on these earnings adjustments is included on page 118. The Group’s Underlying EBIT decreased by US$2,351 million (or 59 per cent) to US$1,616 million, as Underlying depreciation and amortisation increased by US$130 million to US$918 million primarily due to the inclusion of Sierra Gorda in our portfolio.

Net finance income/(costs) The Group’s FY23 Underlying net finance costs of US$188 million primarily comprise the unwinding of the discount applied to our closure and rehabilitation provisions (US$113 million), interest on lease liabilities (US$56 million) largely for our multi-fuel co-generation facility at Worsley Alumina, and interest on our US$700 million of senior unsecured notes (US$31 million) issued in FY22 to partly fund the Sierra Gorda acquisition. Tax expense The Group’s Underlying income tax expense, which includes our material equity accounted investments, was US$512 million in FY23, for an Underlying ETR of 36.1 per cent. Our Group Underlying ETR reflects our geographical earnings mix and the corporate tax rates of the jurisdictions in which we operate. The impact of the recent changes in Colombian tax legislation, with dividend withholding tax increasing from 10 per cent to 20 per cent and income tax deductions no longer available for royalty payments, has increased Cerro Matoso’s effective tax rate. The Underlying ETR for our manganese business was 43.7 per cent in FY23, including the royalty related tax at Australia Manganese. The Underlying ETR for our Sierra Gorda equity accounted investment was 46.0 per cent in FY23, including royalty related tax. As anticipated, reforms to the Chilean Mining Tax were enacted in August 2023 and will be effective from 1 January 2024, resulting in higher royalty related tax in future periods. Sierra Gorda has a tax stability agreement to December 2028 which defers the effective start date of the mining tax reforms until 1 January 2029. In addition, we have an indemnity from the vendors of our Sierra Gorda acquisition for mining tax changes enacted prior to December 2025, to mitigate the impact of these reforms. We have recorded a receivable of US$48 million (pre-tax) in relation to the indemnity and expect to recover this amount from the vendors in FY24. The Group’s cash tax paid in FY23, excluding equity accounted investments, was US$818 million. This reflected the lagged effect of higher profitability in the prior period, as well as one-off cash taxes paid in relation to our Sierra Gorda acquisition (US$115 million) and non-core royalty sale (US$32 million). 44 OPERATING AND FINANCIAL REVIEW Third party product sales The Group differentiates the sale of its production from the sale of third party products due to a significant difference in profit margin earned on these sales. The table below shows the breakdown between the Group’s production and third party products: US$M Group Production Underlying revenue Related operating costs (net of other income) Group Production Underlying EBIT Underlying EBIT margin on Group production Third party products Underlying revenue Related operating costs (net of other income)(1) Third party Underlying EBIT Underlying EBIT margin on third party products Group underlying results Underlying revenue Related operating costs (net of other income) Underlying EBIT (1) Includes depreciation and amortisation.

Total capital expenditure, excluding equity accounted investments, increased by US$335 million to US$894 million in FY23 as we increased our investment in productivity, improvement and growth activities across our portfolio: – Safe and reliable capital expenditure increased by US$103 million to US$470 million as we invested in Illawarra Metallurgical Coal’s transition to a more efficient single longwall configuration at Appin from FY25, and additional ventilation capacity to enable mining in Appin’s Area 7 until at least 2039; – Improvement and life extension capital expenditure increased by US$6 million to US$64 million as we progressed productivity and decarbonisation projects primarily at Worsley Alumina and Brazil Alumina; – Growth capital expenditure increased by US$159 million to US$256 million at Hermosa as we installed critical path dewatering infrastructure and advanced studies for both Taylor and Clark Deposits; and – Intangibles and capitalised exploration increased by US$67 million to US$104 million, as we extended Cerro Matoso’s mining contract to 2044, and completed multiple exploration programs across our portfolio focused on base metals. Our share of capital expenditure for our material equity accounted investments increased by US$119 million to US$283 million in FY23, reflecting the inclusion of Sierra Gorda in our portfolio. Capital expenditure for our Sierra Gorda equity accounted investment was US$199 million, as the operation invested in deferred stripping and additional tailings storage infrastructure. It also invested to grow future potential copper volumes, executing the plant de-bottlenecking project and progressing study work for the fourth grinding line expansion. Capital expenditure for our manganese equity accounted investments was US$84 million as we invested in additional mining equipment and completed the feasibility study for Australia Manganese’s Eastern Lease South life extension project. 45 SOUTH32 ANNUAL REPORT 2023 FINANCIAL AND OPERATIONAL PERFORMANCE SUMMARY CONTINUED Cash flow The Group generated free cash flow from operations of US$57 million and received net distributions of US$187 million from our equity accounted investments in FY23. Group free cash flow reflected higher expenditure on productivity, improvement and growth projects (+US$335 million) and one-off tax payments in relation to our Sierra Gorda acquisition and non-core royalty sale (+US$147 million). Working capital was largely unchanged over the financial year. The increase in inventories of US$126 million in FY23 reflected a permanent increase related to the restart of Brazil Aluminium, as well as temporary impacts at Mozal Aluminium. Net distributions from our equity accounted investments comprised US$173 million from our manganese equity accounted investments and US$14 million from our Sierra Gorda equity accounted investment. At Sierra Gorda we invested in projects to increase potential copper production, implementing the plant de-bottlenecking project, and progressed studies for the fourth grinding line expansion to support a planned final investment decision in H2 FY24.

Consistent with our commitment to maintain an investment grade credit rating, during the year our current BBB+/Baa1 credit ratings were re-affirmed by S&P Global Ratings and Moody’s, respectively. Our capital management framework remains unchanged, and is designed to promote competition for capital through investment in high returning options or to protect portfolio value, as well as to reward shareholders as our financial performance improves. Demonstrating this, the Board has resolved to pay a fully-franked final ordinary dividend of US 3.2 cents per share (US$145 million) in respect of H2 FY23, representing 41 per cent of Underlying earnings. The Board has also further expanded our capital management program by US$50 million, leaving US$133 million to be returned by 1 March 2024. 46 OPERATING AND FINANCIAL REVIEW Net debt and sources of liquidity Our policies on debt and treasury management are as follows: – Commitment to maintain an investment grade credit rating; – Diversification of funding sources; and – Generally maintain borrowings and holdings of excess cash in US dollars. Gearing and net (debt)/cash The table below presents net (debt)/cash and net assets of the Group, based on the balance sheet as at 30 June 2023: US$M Cash and cash equivalents Current external debt Non-current external debt Net (debt)/cash Net assets Gearing(1) FY23 1,258 (365) (1,376) (483) 9,375 4.9% FY22 2,365 (402) (1,425) 538 10,779 (5.3%) (1) Gearing is the ratio of (Net debt/(cash)) to (Net debt/(cash)) plus Net assets. Funding sources In addition to cash flow from operations as a primary source of funding, the Group has US$700 million of senior unsecured notes outstanding, which are due in 2032 and accrue interest at a rate of 4.35 per cent per annum. We also retain access to significant liquidity, through an undrawn, sustainability-linked revolving credit facility, to have available capacity of US$1.4 billion to December 2026, and US$1.2 billion to December 2027. This facility is a standby arrangement to the Group’s US dollar commercial paper program and is not subject to financial covenants at the Group’s current credit rating. Certain financing facilities in relation to specific operations are the subject of covenants that vary from facility to facility; however, these are considered normal for such facilities. Additional information regarding the maturity profile of the Group’s debt obligations and details of our major standby agreement is included in note 19 to the financial statements on pages 142 to 149.

Bauxite is mined near the town of Boddington, 130 kilometres south-east of Perth. It is transported by overland conveyor to the alumina refinery near Collie and turned into alumina powder, before being transported by rail to Bunbury port. It is then shipped to smelters around the world, including our Hillside Aluminium and Mozal Aluminium smelters in southern Africa. We are executing decarbonisation and energy security initiatives at Worsley Alumina, including commencing the conversion of the first coal-fired boiler to natural gas.

Total Recordable Injury Frequency (TRIF) was 8.6 in FY23, a 32 per cent increase year-on-year. Volumes Worsley Alumina saleable production decreased by four per cent (or 152kt), from record levels in FY22, to 3,839kt in FY23. The refinery successfully managed short-term energy supply challenges and completed planned calciner maintenance in Q1 and Q3 FY23, finishing the year with production rates above nameplate capacity in Q4 FY23. Operating costs Operating unit costs increased by 10 per cent to US$291/t in FY23, as the benefit of a weaker Australian dollar was more than offset by higher uncontrollable costs including an increase in caustic soda (FY23: US$659/t, FY22: US$581/t) and coal prices. Financial performance Underlying EBIT decreased by 82 per cent (or US$318 million), to US$68 million in FY23, as a 13 per cent decrease in the average realised price of alumina (-US$198 million), lower sales volumes (-US$64 million) and higher inflation and uncontrollable costs (-US$74 million), more than offset the benefit of a weaker Australian dollar (+US$50 million). The operation also incurred additional contractor costs (-US$18 million) to deliver planned maintenance activity. Capital expenditure Safe and reliable capital expenditure was US$49 million in FY23 as we invested in infrastructure to enable access to new mining areas and continued to invest in additional bauxite residue disposal capacity. Improvement and life extension capital expenditure was US$33 million in FY23 as we advanced decarbonisation projects at the refinery. Social investment We invested US$1.1 million in communities around Worsley Alumina in FY23, with a focus on natural resource resilience, economic development, good health and social wellbeing, and education and leadership programs. + Learn more about Worsley Alumina at www.south32.net. 48 OPERATING AND FINANCIAL REVIEW BRAZIL ALUMINA Location: Pará and Maranhão, Brazil South32 investment: Bauxite - 33 per cent South32 share: Alumina - 36 per cent South32 holds a 33 per cent interest in the non- operated Mineração Rio do Norte (MRN) bauxite mine. Vale holds 40 per cent, Rio Tinto Alcan holds 12 per cent, Companhia Brasileira de Aluminio S.A. holds 10 per cent and Hydro holds five per cent. The MRN mine is an open-cut strip mining operation. Mined ore is hauled to primary crushers and then transported by conveyor belt to the beneficiation plant. A feasibility study is underway for the West Zone project at MRN, with the potential to extend the mine life by more than 20 years. The bauxite produced from the MRN mine is sold to its shareholders. Our share of bauxite produced from MRN is supplied to the Alumar alumina refinery. We govern our share of MRN through participation in MRN’s Board, the main governance forum responsible for the strategic direction and oversight of MRN. We also hold a 36 per cent share of the non-operated Alumar alumina refinery. Alcoa holds 54 per cent and Rio Tinto Alcan holds 10 per cent. A de-bottlenecking project at the refinery is expected to lift capacity from FY26. The alumina produced from the refinery is exported through the Alumar port and supplied to the co-located Alumar aluminium smelter. We govern our share of Alumar through participation in the Supervisory Committee, the main governance forum responsible for the strategic direction and oversight of Alumar.

Operating costs Operating unit costs increased by 28 per cent to US$368/t in FY23, with a significant rise in uncontrollable costs accounting for more than 70 per cent of this increase, together with one-off costs associated with the port infrastructure outages. Uncontrollable cost inflation, including higher caustic soda prices (FY23: US$722/t, FY22: US$425/t), coal-linked energy prices, and bauxite costs linked to alumina and aluminium prices on a trailing basis, was most acute in H1 FY23, with these input prices all trending lower in H2 FY23. Financial performance Underlying EBIT decreased by US$134 million, to a loss of US$45 million in FY23, as an eight per cent decrease in the average realised price of alumina (-US$38 million), lower sales volumes (-US$30 million) and higher uncontrollable costs (-US$72 million), more than offset higher profit from our equity accounted interest in MRN (+US$10 million). Capital expenditure Safe and reliable capital expenditure decreased by US$6 million to US$45 million in FY23 as we continued our investment in bauxite residue disposal capacity. Improvement and life extension capital expenditure was US$13 million in FY23 as the refinery progressed work on the de-bottlenecking project. + Learn more about Brazil Alumina at www.south32.net.

Lower overhead crane availability in Q4 FY23 delayed pot restart activities and metal production. Operating costs Brazil Aluminium recorded gross operating costs of US$295 million in FY23 as the smelter continued to ramp-up and raw material input prices remained elevated across the industry. Financial performance Underlying EBIT was a loss of US$136 million in FY23, as sales revenue (+US$166 million) was more than offset by costs to support the smelter’s restart and ramp-up of all three potlines (-US$258 million). Capital expenditure Safe and reliable capital expenditure was US$9 million in FY23 as the restart of the Aluminium smelter progressed. + Learn more about Brazil Aluminium at www.south32.net. South32 holds a 40 per cent share in the non- operated Alumar aluminium smelter, which was restarted during FY22 after being on care and maintenance since 2015. Alcoa Corporation holds a 60 per cent share. Following the restart, first production was achieved in the June 2022 quarter, with nameplate capacity from the smelter’s three potlines expected to be achieved in FY26. It has a solid metal production capacity of 447kt per year (on a 100 per cent basis) and produces standard aluminium ingots for the domestic and export markets. Our share of Brazil Aluminium is powered by 100 per cent cost efficient renewable power.

Volumes Hillside Aluminium saleable production increased by one per cent (or 5kt) to a record 719kt in FY23 as the smelter continued to test its maximum technical capacity, despite the impact of elevated load-shedding. Operating costs Operating unit costs increased by two per cent to US$2,178/t in FY23, as the benefit of a weaker South African rand and lower alumina prices, was more than offset by elevated smelter raw material input prices (including coke, pitch and aluminium tri- fluoride), and inflation-linked indexation of energy costs. Financial performance Underlying EBIT decreased by 71 per cent (or US$475 million), to US$191 million in FY23, as the benefit of a weaker South African rand (+US$106 million) and higher sales volumes (+US$18 million), was more than offset by a 20 per cent reduction in the average realised price of aluminium (-US$449 million) and higher raw material input prices (-US$56 million) and energy costs (-US$66 million). Ninety-six pots were relined at a cost of US$281,000 per pot in FY23 (FY22: 162 pots at US$274,000 per pot). The smelter is deploying AP3XLE technology in its pot relining program, which is expected to enhance the smelter’s energy efficiency and reduce GHG emissions. Capital expenditure Capital expenditure was US$18M in FY23 as the smelter invested in plant upgrades and continued to roll-out the AP3XLE energy efficiency technology in its pot relining program. Social investment We invested US$9.1 million in communities around Hillside Aluminium in FY23, with a focus on enterprise development, education, and development of sustainable agricultural practices. + Learn more about Hillside Aluminium at www.south32.net. 51 SOUTH32 ANNUAL REPORT 2023 FINANCIAL AND OPERATIONAL PERFORMANCE SUMMARY CONTINUED MOZAL ALUMINIUM Location: Maputo, Mozambique South32 share: 63.7 per cent South32 holds a 63.7 per cent share of Mozal Aluminium. The Industrial Development Corporation of South Africa Limited holds 32.4 per cent and the Government of the Republic of Mozambique holds 3.9 per cent (through preference shares). Safety Tragically, two of our colleagues, Mr Cristovão Alberto Tonela and Mr Alfredo Francisco Domingos João, lost their lives in a fatal incident at Mozal Aluminium in November 2022. Our deepest sympathies remain with their families and colleagues to whom we have provided support and counselling. Mozal Aluminium is located 20 kilometres west of Mozambique’s capital city Maputo and has a solid metal production capacity of 580kt per year (on a 100 per cent basis). LTIF at Mozal Aluminium was 0.4 in FY23, a 100 per cent increase year-on-year. TRIF was 1.5 in FY23, a 67 per cent increase year-on- year. Mozal Aluminium is the only aluminium smelter in Mozambique and the second largest aluminium smelter in Africa (behind our Hillside Aluminium smelter in South Africa). It produces standard aluminium ingots for the domestic and export markets. To support the development of the downstream aluminium industry in Mozambique a portion of liquid metal is supplied to Midal Cables, a local company that sells products in the domestic and export markets. Deployment of the AP3XLE energy efficiency technology is well advanced at Mozal Aluminium and expected to conclude in FY24.

Operating costs Operating unit costs increased by four per cent to US$2,329/t in FY23, as the benefit of a weaker South African rand and lower alumina prices, was more than offset by elevated smelter raw material input prices (including coke, pitch and aluminium tri- fluoride), and inflation-linked indexation of energy costs. Financial performance Underlying EBIT decreased by 79 per cent (or US$215 million), to US$56 million in FY23, as the benefit of our additional interest in Mozal Aluminium and a weaker South African rand (+US$26 million), was more than offset by a 21 per cent decrease in the average realised price of aluminium (-US$182 million), lower sales volumes (-US$48 million) and higher raw material input prices (-US$8 million) and energy costs (-US$17 million). Eighty-two pots were relined in FY23 at a cost of US$318,000 per pot as the pot relining schedule was modified with the smelter’s recovery plan (FY22: 127 pots at US$266,000 per pot). The smelter is deploying AP3XLE technology in its pot relining program, which is expected to deliver incremental production benefits, with no associated increase in power consumption. Capital expenditure Capital expenditure was US$17 million in FY23 as the smelter invested in plant upgrades and continued to roll-out the AP3XLE energy efficiency technology in its pot relining program. Social investment We invested US$1.8 million in communities around Mozal Aluminium in FY23, with a focus on education and skills development, health, sanitation, community wellbeing, and development of sustainable agricultural practices. + Learn more about Mozal Aluminium at www.south32.net.

Safety LTIF at Cannington was 4.3 in FY23, a 187 per cent increase year- on-year. TRIF was 11.0 in FY23, a 21 per cent increase year-on- year. Volumes Cannington payable zinc equivalent production decreased by 13 per cent to 195.6kt in FY23, as the operation successfully recovered from severe weather impacts in Q3 FY23. Operating costs Operating unit costs increased by 15 per cent to US$153/t in FY23, as the benefit of a weaker Australian dollar and lower price-linked royalties was more than offset by lower mill throughput. Financial performance Underlying EBIT decreased by 55 per cent (or US$173 million), to US$142 million in FY23, as lower zinc and lead prices (-US$75 million) and reduced sales volumes (-US$119 million), more than offset the benefit of a weaker Australian dollar (+US$21 million) and lower price-linked royalties (+US$10 million). Capital expenditure Capital expenditure increased by US$16 million to US$61 million in FY23 as we invested in additional tailings storage capacity and upgrades to water and ventilation infrastructure. Social investment We invested US$0.5 million in communities around Cannington in FY23, with a focus on education, local economic participation, natural resource resilience, and community wellbeing. + Learn more about Cannington at www.south32.net. Cannington consists of an underground hard rock mine and surface processing facility, a road-to-rail transfer facility and a concentrate handling and ship loading facility at the Port of Townsville. Silver, lead and zinc are extracted from the ore using grinding, sequential flotation and leaching techniques that produce high- grade, marketable lead and zinc concentrates with a high silver content.

TRIF was 1.6 in FY23, a 43 per cent decrease year- on-year. Volumes Cerro Matoso payable nickel production decreased by two per cent to 40.8kt in FY23, as the benefits of the OSMOC project were offset by a temporary access restriction to the higher-grade Queresas and Porvenir (Q&P) pit. The OSMOC project is expected to partially offset natural grade decline. Operating costs Operating unit costs increased by 16 per cent to US$5.03/lb in FY23, as the benefit of a weaker Colombian peso was more than offset by higher labour and contractor costs, including the delivery of the OSMOC project. Financial performance Underlying EBIT decreased by 59 per cent (or US$274 million), to US$189 million in FY23, as a 23 per cent decline in the average realised nickel price (-US$209 million), reduced sales volumes (-US$22 million) and increased labour and contractor costs (-US$20 million), was partially offset by a weaker Colombian peso (+US$48 million). Capital expenditure Safe and reliable capital expenditure increased by US$15 million to US$33 million in FY23 as we progressed planned furnace upgrades and invested in a new mobile fleet. Improvement and life extension capital expenditure decreased by US$14 million to US$5 million in FY23 following the successful commissioning of the OSMOC project in H1 FY23. The extended mining contract underpinned by the OSMOC project is expected to unlock existing resources and creates an opportunity to analyse options to optimise our product mix in the battery supply chain. As part of this, we progressed concept studies to assess the potential to produce intermediary nickel products for electric vehicle markets.

Diversity representation Inclusion and diversity is a core element of our culture. We know an inclusive and diverse workforce is safer and allows for greater collaboration, innovation and performance. Our Inclusion and Diversity Policy was updated and approved by our Board in July 2023 and is available at www.south32.net. We are committed to building and maintaining an inclusive and diverse workforce that reflects the communities in which we operate. Diversity is a key attribute of high performance in a well-functioning Board and Lead Team, and offers benefits including varied thoughts and perspectives along with unique insights and healthy challenge, which lead to better decision-making as we execute our strategy. We consider inclusion and diversity in tandem, grounded in mutual respect, where each person’s unique differences are recognised, valued, and celebrated. Our vision for diversity considers the broadest definition of difference, including gender, ethnicity, nationality, cultural background, geographic location, language/accent, religious beliefs, socio-economic background, neurodiversity, disability, physical attributes, appearance, age, education, family responsibilities and sexuality.

For South32, the senior positions on the Board are only the Chair and the CEO. In line with market practice for Australian listed companies, the CFO does not sit on the Board and South32 does not have a SID as this role is not required under the corporate governance code South32 applies, being the ASX Principles and Recommendations. (2) In accordance with the UK Listing Rules, Executive Management includes the Lead Team (our most senior executive body below the Board) and the Company Secretary, excluding administrative and support staff. 72 GOVERNANCE                     The FCA introduced new rules in 2022 that require listed companies to publish information on gender and ethnic representation of the Board and Executive Management. In addition, the FCA requires listed companies to disclose against diversity targets, specifically that at least 40 per cent of the Board are women, at least one of the senior Board positions is a woman and at least one member of the Board is from a non-white ethnic minority background. South32 meets or exceeds all of these targets, as set out in Table 1.2. The data presented in Table 1.2 was collected via self-reported questionnaires completed by all members of the Board and Executive Management that included the definitions prescribed by the UK Listing Rules.

We have reflected on this tragic event and have captured and shared learnings across our business and industry, implemented additional controls at our aluminium smelters and identified further safety improvement opportunities. Throughout FY23, we continued to implement our multi-year Safety Improvement Program designed with the aim of enhancing our safety culture and achieving a step change in our safety performance. While we exceeded several of our safety performance lead measures, notably in risk management and safety leadership, our Total Recordable Injury Frequency did not meet target, increasing by 11 per cent to 5.9 per million hours worked. For more information on our health and safety performance in FY23, and FY24 focus areas, please refer to our Sustainable Development Report available at www.south32.net. Other important sustainability measures include our water performance and social investment. In FY23 we achieved more than two per cent improvement in water use efficiency collectively across our four operations in areas defined as having baseline water stress, and we invested US$27.7 million in community programs. As part of the evolution of our approach to social performance we also developed economic development plans, which include local employment and procurement targets, at all operations for the first time. We know that an inclusive and diverse workforce produces better outcomes and is an important enabler to further embed our 'safety guarantee' across our business. This year we increased the representation of women on our Lead Team to 50 per cent and Operational Leadership Team to 29 per cent, and in the total workforce to 20 per cent. In addition, we progressed initiatives to create a more inclusive workplace, in which any form of inappropriate conduct is not tolerated. Against a volatile global backdrop, in FY23 we delivered strong production growth in aluminium, base metals and manganese, underpinned by our recent portfolio improvements and annual production records at three of our operations. This strong production growth supported one of our largest underlying profit results to date, with Underlying EBITDA of US$2.5 billion, notwithstanding lower commodity prices and industry-wide inflationary pressures. This, in turn, supported continued strong shareholder returns in respect of FY23, including dividends totalling US$369 million and a further US$218 million returned via our ongoing on-market share buy-back. We continue to reshape our portfolio toward commodities that are critical in the transition to a low carbon world and in FY23 we progressed work to support planned investment decisions for the development of the Hermosa project’s Taylor zinc-lead-silver Deposit and confirmed the opportunity to produce battery-grade manganese from Hermosa’s Clark Deposit. Our performance across the year is recognised in our FY23 Business Scorecard, where an overall outcome of 83.8 per cent (out of a possible 150 per cent) was achieved. See page 89 for more information. Application of the Business Modifier The Business Modifier is an integral component of the short-term incentive (STI) that considers overall business outcomes or other factors that are not specifically contemplated in the Business Scorecard, to ensure unintended reward outcomes are avoided. When considering the application of the Business Modifier for FY23, the Board primarily focused on two matters, the tragic loss of our two colleagues who were fatally injured in the incident at Mozal Aluminium, and the non-cash impairment expense of US$1.3 billion recognised in our FY23 financial results in relation to the Taylor Deposit at Hermosa. In recognition of these events, the Board chose to exercise its discretion by reducing the overall STI outcome for the CEO by 25 per cent. A reduction ranging from 5 to 20 per cent has also been applied to the STI outcome of other Executive key management personnel (KMP) and members of the Lead Team. The application of the Business Modifier reflects our commitment to everyone going home safe and well and overall reward outcomes that reflect our performance and the shareholder experience. 78 GOVERNANCE FY23 reward outcomes Our executive reward framework remained unchanged for FY23 following strong support at our 2022 Annual General Meeting, with over 98 per cent of shareholders voting in favour of the 2022 Remuneration report. The reward framework consists of fixed remuneration, STI and long-term incentives (LTI). In September 2022, fixed remuneration increases were applied for the CEO and Executive KMP following our annual benchmarking exercise. These increases were aligned to the broader workforce and recognised the extensive skill sets of our CEO and Executive KMP. The intent of the STI is to focus our executives on what they can influence in the performance year, so we remove the impacts of external factors such as commodity price volatility and foreign exchange rate movements. Taking into consideration the FY23 Business Scorecard outcome, including the Business Modifier, the CEO STI was 42 per cent of maximum, with other Executive KMP ranging from 40 to 74 per cent of maximum (see page 92). The LTI is the component of executive remuneration most closely linked to the shareholder experience as it rewards executives for the delivery of returns that exceed peer benchmarks across a four-year period. While South32 delivered a total shareholder return (TSR) of 41 per cent over the four-year performance period of the FY20 LTI, our TSR fell short of the threshold required for vesting. As a result, all FY20 LTI awards lapsed in full for the fourth consecutive year. We only grant performance tested LTI awards to permanent members of the Lead Team, including those designated as KMP. However, we do not penalise executives when they are promoted to the Lead Team and allow them to retain awards granted when they were in prior management roles, with the respective vesting conditions. As a result, our Chief Financial Officer and Chief Operating Officers continue to hold service-based awards that were previously granted to them prior to their permanent promotion to the Lead Team, which the Board approved to vest in August 2023. For more information on LTI, see pages 93 and 94. Continuing from last year, we have included an update for our strategic measures highlighting key activities in FY23 (refer to page 95 for this update). This year, for the first time, we have also disclosed our CEO pay ratio in line with the Global Reporting Initiative and ICMM requirements. Our FY23 CEO pay ratio is 26:1. For more information on how this is calculated, see page 82. Looking forward to FY24 In order to continue to pay executives appropriately, we annually benchmark KMP remuneration against similar-sized Australian listed companies and global mining companies that reflect the size, commodity mix, complexity and global presence of South32. Following completion of this process, the Board decided to award a four and a half per cent increase to the fixed remuneration of our CEO in recognition of his extensive experience and skill set after eight years in the role and consistent with the approach taken with the broader workforce. Fees for Non-Executive Directors will remain unchanged. See page 99 for further information about changes to Executive KMP fixed remuneration in FY24. Following the adjustments made to the reward framework effective from FY22, no major changes are being made for FY24. We are, however, strengthening the link between safety and reward through an increased weighting in the Business Scorecard. See page 99 for our FY24 STI performance metrics and weightings. We look forward to continuing to engage with shareholders and sharing in the future success of South32. Thank you for your support.

Prior to this, she was Vice President Finance. FY23 Executive remuneration overview CEO fixed remuneration increase: Range of Executive KMP STI outcomes as a percentage of maximum STI opportunity: 5.0% 40% to 74% FY20 LTI vesting outcome: 0.0% Fixed remuneration The Board awarded a five per cent increase to the fixed remuneration of our CEO, Graham Kerr, from 1 September 2022 in recognition of his extensive experience and skill set, and consistent with the approach taken with the broader workforce. This was his second increase in fixed remuneration since commencing as CEO in 2015. Fixed remuneration for other Executive KMP was also increased by between five and six per cent in recognition of their experience and aligned with the increases applied to the broader workforce in the relevant geographies (Australia and South Africa). FY23 STI In FY23, our performance against our Business Scorecard measures resulted in an outcome of 83.8 per cent (out of a possible 150 per cent). Furthermore, the Board determined to apply a negative Business Modifier for all Executive KMP in recognition of the two fatalities at Mozal Aluminium and, for the CEO, in recognition of the non-cash impairment for the Taylor Deposit at our Hermosa project. This resulted in a negative Business Modifier of 25 per cent for Graham, 20 per cent for Noel Pillay, 10 per cent for Jason Economidis and 5 percent for Sandy Sibenaler and Katie Tovich respectively. The overall STI outcome for Executive KMP ranged from 40 per cent to 74 per cent of maximum with Graham receiving 42 per cent. LTI vesting in 2023 While South32 delivered TSR of 41 per cent over the four-year performance period, this fell short of the threshold required for vesting when compared to the two performance benchmarks. As a result, all FY20 LTI rights lapsed. South32 does not offer retention rights to permanent members of the Lead Team, including those that are Executive KMP. However, employees who are promoted into Executive KMP roles retain unvested awards granted under the Management Share Plan (MSP) while in their prior role. These awards are a combination of performance rights and retention rights. As the service-based condition of the MSP retention rights granted to Sandy, Jason and Noel prior to their permanent appointment to the Lead Team was met, our Board approved these awards to vest in full in August 2023. FY23 realised pay Realised pay for Executive KMP (see page 82) was below Target Remuneration (see page 86) as the FY20 LTI did not vest, the Business Scorecard outcome was below target and the Board applied a negative Business Modifier when determining the STI outcome. The Board considered all components of remuneration in reviewing the FY23 reward outcomes to align with our Guiding Principles (see page 83) and believes the FY23 realised pay is fair for Executive KMP and shareholders, based on performance for the year. 81 SOUTH32 ANNUAL REPORT 2023 REMUNERATION REPORT CONTINUED Realised pay for Executive KMP in FY23 Realised pay is the value of reward received by Executive KMP in relation to the financial year, rather than potential pay that may be earned or disclosed statutory pay. We publish this information to enable our shareholders to better understand the pay delivered to our Executive KMP through our reward framework (including the application of Board discretion) and how this is aligned to the performance of South32 over time. The intention of our reward framework (see our Guiding Principles on page 83) is to deliver realised pay outcomes that reflect Company performance and the shareholder experience. The Board and Remuneration Committee believe that our realised pay outcomes reflect this objective. FY23 realised pay for Executive KMP, outlined in Table 1.3, includes: – Fixed remuneration earned in FY23 (including pension/superannuation); – Other cash and non-monetary benefits earned in FY23; – Total FY23 STI earned (including cash and deferred rights) based on performance during this financial year (see page 92); and – LTI awards that vested based on performance and/or service conditions to 30 June 2023 (see page 94). Realised pay is likely to vary substantially, either up or down, from statutory remuneration and from Target Remuneration (see page 86) because a significant portion of our Executive KMP pay is ‘at risk’ and based on challenging performance measures. Furthermore, as the LTI is measured over a four-year performance period, vesting outcomes will not always correlate to the TSR outcomes for a single year. In comparison to FY22, FY23 realised pay reflects the lower overall STI outcomes.

(3) LTI includes Management Share Plan awards granted to S Sibenaler, J Economidis and N Pillay prior to their permanent appointment to the Lead Team (see page 93). FY22 LTI includes the FY20 Transitional LTI award granted to K Tovich on appointment to the Lead Team. (4) K Tovich ceased to be CFO and a member of Executive KMP on 31 March 2023. Following this, she was appointed as CHRCO. FY23 realised pay reflects nine months as CFO and three months as CHRCO. (5) S Sibenaler became CFO and a member of Executive KMP on 1 April 2023. Prior to this, she was Vice President Finance. FY23 realised pay reflects nine months in her prior role and three months as CFO. (6) Other for S Sibenaler includes the pro-rated payout of a retention agreement of A$35,500 relating to her service as Vice President Finance that was paid prior to becoming a member of Executive KMP. (7) N Pillay became COO Africa and Colombia on 1 October 2021 and a member of Executive KMP on 1 December 2021. Prior to this, N Pillay was Vice President Operations at Worsley Alumina. FY22 realised pay reflects three months in his prior role and nine months as COO. Salary relating to his time as COO is denominated in ZAR and has been converted to A$ using an exchange rate of AUD:ZAR 11.96 for FY23 and AUD:ZAR 11.13 for FY22. (8) FY22 Other amounts for N Pillay include benefits provided to him to assist with his relocation from Australia to South Africa. These include a relocation allowance of ZAR1,500,000 paid on 25 October 2021 which has been converted to A$ using an exchange rate of AUD:ZAR 10.99. CEO Pay Ratio As part of our commitment to pay transparency, we have calculated the ratio of our CEO’s total realised pay to the median total realised pay for all our employees globally. This results in an FY23 CEO pay ratio of 26:1 which reflects an STI outcome for the CEO that was below target and no LTI vesting. The pay ratio is expected to vary from year to year, given the significant portion of our CEO's pay which is 'at risk'. CEO total realised pay has been calculated in accordance with the method used in Table 1.3. For all other employees realised pay is for the 12-month period to 30 June 2023 and includes all allowances, annual incentive payments received in the period and the value of shares that vested, but excludes other non-monetary benefits. Pension contributions have been calculated based on the cost to the Group of the contributions made in the 12-month period. Internationally mobile employees and employees who joined or left the Group after 1 July 2022 have been excluded from the calculation. 82 GOVERNANCE Our reward framework The pages of the Remuneration report that follow (together with Table 1.1 – Business performance) have been prepared in accordance with section 300A of the Corporations Act 2001 (Cth) (the Act) and audited as required by section 308(3C) of the Act. These sections relate to those persons who were KMP of South32 during FY23, being the individuals listed in Table 1.2 on page 81. Remuneration governance The roles and responsibilities of our Board, Remuneration Committee, management and external advisors in relation to remuneration for Executive KMP and employees of South32 are outlined below. Board Our Board maintains overall responsibility for overseeing the remuneration policy and the principles and processes that underpin it. It approves the remuneration arrangements for our CEO and Non- Executive Directors. Changes to the Director fee pool and equity grants to the CEO are approved by shareholders. Remuneration Committee The Remuneration Committee approves reward arrangements for our Executive KMP (other than the CEO) and oversees the remuneration and benefits framework for all employees of South32. By taking advice from other Board Committees (such as the Sustainability and Risk and Audit Committees), the Remuneration Committee helps the Board oversee our remuneration policy, its specific application to the CEO, executives and Non-Executive Directors and, in general, our employees. The Remuneration Committee provides oversight to gain assurance that remuneration arrangements are equitable and aligned to the long-term interests of shareholders, operate within risk appetite and support our purpose, strategy and values. CEO and management Our CEO makes recommendations to the Remuneration Committee regarding our executives, and how the remuneration policy and framework applies to our employees. Management provides information and recommendations to the Remuneration Committee to help them consider and implement approved arrangements. External advisors Independent external advisors may be engaged either directly by the Remuneration Committee, or via management. These advisors provide information on remuneration-related issues, including benchmarking information and market data. The Remuneration Committee did not receive recommendations from external advisors, including remuneration consultants, in relation to KMP in FY23. We seek information and analysis from a range of data sources. This allows us to make decisions that are informed, objective, weighted and aligned to the requirements of the Company, and consistent with our Guiding Principles. Reward practices and outcomes Our Guiding Principles Purpose and Strategy The way we work Shareholders Performance Market We align short-term and long-term performance measures to our purpose and strategy. This includes our efforts to: – Optimise our business by working safely, minimising our impact, consistently delivering stable and predictable performance and continually improving our competitiveness; – Unlock the full value of our business through our people, innovation, projects and technology; and – Identify and pursue opportunities to sustainably reshape our business for the future, and create enduring social, environmental and economic value. Our culture is grounded in our values and is at the core of how we deliver our purpose and strategy. You’ll see it reflected in our values, the decisions we take, the courage we show and the legacy we leave. Supporting this is a strong belief that culture can be actively shaped through a focus on what we prioritise, what we measure, what we reward and who we appoint. Our reward framework focuses executives and management on delivering superior TSR. We do this through share ownership and LTI performance measures aligned to the shareholder experience. We value feedback and regularly check-in with investors and proxy advisors. Our reward outcomes align to performance by providing a large part of executive pay ‘at risk’ based on challenging financial and non- financial measures. STI outcomes reflect performance over the financial year, while LTI outcomes reflect performance over a four-year period. Our reward is competitive and designed to attract and retain talented executives. We benchmark our reward levels in consideration of similar sized companies on the Australian Securities Exchange (ASX), as well as our global mining peer group. 83 SOUTH32 ANNUAL REPORT 2023 REMUNERATION REPORT CONTINUED Components of our reward for FY23 Our intention Attract and retain talented executives to lead South32 The majority of pay at risk reflects our commitment to pay for performance and deliver value to shareholders Reward business and individual performance in the financial year Drive long-term performance and ownership behaviours Component Fixed Remuneration Short-Term Incentive Long-Term Incentive The why Fixed remuneration is set with reference to the median of our peer groups, reflecting each member of Executive KMP’s responsibilities, location, skills and experience. STI focuses efforts on our key priorities both in the financial year and into the future. It aims to motivate Executive KMP to achieve challenging performance objectives. Our STI reflects performance during the year and measures outcomes within management’s control. LTI is directly linked to: – Relative TSR so that Executive KMP pay outcomes are aligned with the shareholder experience over the longer- term; and – Two strategic measures so that Executive KMP pay outcomes are aligned to the business priorities that we believe will underpin the long-term success of South32. The how Base salary and superannuation. Our approach in FY23 We benchmark our fixed remuneration and Target Remuneration against two key peer groups that reflect our profile as a Company and the markets in which we operate. Our peer groups are: – An ASX peer group based on companies with half to double our market capitalisation (excluding foreign domiciled entities and real estate investment trusts); and – An international mining peer group of 18 companies with a similar market capitalisation, commodity mix and/or global presence to South32 (see Our global mining peer group below). Fifty per cent paid in cash annually. Fifty per cent delivered in rights to receive South32 shares(1), deferred for two years(2). Quantum (percentage of fixed remuneration): Target Value Maximum Opportunity Executive KMP 120% 180% Business Scorecard: The Business Scorecard reflects a balance of financial and non-financial measures that are a priority for us in the financial year. The financial measures remove the impact of commodity prices and foreign exchange so that we reward for items management can control. Performance measures: ■ Sustainability (28.3%) ■ Financial: Production, cost and capital expenditure (28.3%) ■ Financial: Adjusted ROIC (28.3%) ■ Strategic priorities (15%) Business Modifier: As scorecard measures do not always reflect all aspects of performance across a year, and to mitigate any unintended reward outcomes, the Board has the discretion to apply a Business Modifier to the Business Scorecard outcome. The Business Modifier may be applied to Executive KMP on an individual or group basis, having regard to the perspectives of stakeholders including employees, shareholders and communities. Individual performance and behaviours: The Board also considers each member of Executive KMP’s individual performance, taking into account their areas of responsibility and the alignment of their behaviours with our values (i.e. how outcomes have been achieved). Rights to receive South32 shares that are subject to meeting performance conditions over the four-year performance period. Quantum (percentage of fixed remuneration): The quantum for FY23 was determined by multiplying fixed remuneration by the following face value percentages: CEO Other KMP Performance measures: Target Value Face Value 120% 80% 200% 133% ■ TSR relative to EMIX Global Mining Index constituents (53.3%) ■ TSR relative to MSCI World Index (26.7%) ■ Climate change strategic measure (10%) ■ Portfolio management strategic measure (10%) TSR performance: Eighty per cent of the LTI is assessed based on our TSR performance compared to two comparator groups, being: – Two-thirds, or 53.3 per cent of the total award, is tested relative to the TSR performance of the companies that comprise the EMIX Global Mining Index at the start of each performance period (i.e. at 1 July 2022 for FY23 LTI award) (3); and – One-third, or 26.7 per cent, is tested relative to the TSR of the MSCI World Index. Strategic measures: The strategic measures, which each have a weighting of 10 per cent of the LTI, are: – Our response to climate change; and – The transition of our portfolio towards the commodities critical to a low-carbon future. More detail on the measures and our progress against them is outlined on page 95. Vesting Scale: Vesting outcome(4) 0% 40% 100% EMIX Global Mining Index constituents* TSR <= 50th percentile TSR > 50th percentile MSCI World Index* TSR < Index TSR = Index TSR => 75th percentile TSR => Index + 23.9% Vesting outcomes will be determined by the Board at the end of the performance period. Strategic Measures *Vesting between 40 per cent and 100 per cent is on a straight-line basis. The the Board has the discretion to adjust the TSR vesting outcome (both upwards and downwards) so that the overall vesting outcome is appropriate and aligned with our Guiding Principles (see page 83). There is no retesting if the performance condition is not met at the end of the performance period. 84 GOVERNANCE Our global mining peer group Minimum shareholding requirement Our service contracts The global mining peer group that we use as one of our reference points for benchmarking fixed remuneration and total reward levels includes the following companies: Agnico Eagle Mines, Alcoa, Anglo American, AngloGold Ashanti, Antofogasta, Barrick Gold, Evolution Mining, First Quantum Minerals, Fortescue Metals Group, Freeport McMoRan, Gold Fields, Kinross Gold, Lundin Mining, Newcrest Mining, Newmont, Northern Star Resources, Teck Resources and Vedanta. A minimum shareholding requirement (MSR), equal to 100 per cent of fixed remuneration for Executive KMP, drives a long- term focus and alignment with our shareholders. The MSR applies to all Lead Team members, including those who are Executive KMP, and must be obtained within five years of appointment to the Lead Team. The valuation approach applied to determine the MSR uses the South32 Ltd share price at the time the assessment is made. See page 102 for our Executive KMP shareholdings. Contracts are entered into by Executive KMP in their personal capacity. The key terms are consistent for all Executive KMP, and include: – No fixed term; – Six months’ notice by either party or payment by the company in lieu of notice; – Termination without notice for serious misconduct; – One month’s notice by the Executive KMP(5) where a fundamental change occurs that materially diminishes their status, duties, authority or terms and conditions (receiving payment in lieu of six months’ notice); – A maximum payment in lieu of notice of six months’ fixed remuneration; and – Post-employment restraints for a period of up to six months after their employment with the Group ends. Shareholder approval was granted at the 2021 Annual General Meeting (AGM) for Executive KMP termination benefits. (1) References in this Remuneration report to ‘South32 shares’ are references to fully paid ordinary shares in South32 Limited. (2) The deferred rights are subject to a service condition only as performance conditions are applied during the STI performance year. (3) The constituent group is fixed for the four-year performance period with Board discretion to adjust the constituent group to take into account events such as takeovers, mergers or demergers that may occur during the performance period. (4) The Board and Remuneration Committee use information from an external provider to inform them of the TSR performance of the relevant index and companies to assess the vesting outcome for the LTI. (5) Some legacy executive employment contracts, including for the CEO, allow resignation without notice if a fundamental change occurs. Linking reward and environmental, social and governance (ESG) topics The ‘at risk’ components of our Executive KMP reward reflects ESG topics that align remuneration outcomes not just with financial performance but also with our performance against ESG measures that underpin our business outcomes, as explained below. STI The Business Scorecard reflects a balance of financial and non-financial measures that reflect the key focus areas for us in the financial year. From an ESG perspective, 28.3 per cent of the FY23 Business Scorecard was assessed against ‘sustainability’ metrics, which include safety performance, health, community, risk management and water efficiency. The overall Business Scorecard outcome is also subject to the Business Modifier. The Business Modifier allows the Board to appropriately adjust the Business Scorecard outcome to account for ESG-related topics. We have a track record of applying the Business Modifier to reflect non-financial performance and the overall shareholder experience (see page 91). Further detail on our STI is included in the Short-Term Incentive for FY23 section starting on page 88. LTI Twenty per cent of the FY23 LTI directly links executive reward to climate change and the transition of our portfolio toward the commodities critical to a low-carbon future. More detail on the strategic measures and our progress against them is outlined on page 95. 85 SOUTH32 ANNUAL REPORT 2023 REMUNERATION REPORT CONTINUED Target Remuneration for FY23 South32 sets Target Remuneration for each member of Executive KMP at a competitive level to attract and retain appropriate talent in the markets in which we operate. Our Target Remuneration is informed by the South32 reward framework (see page 83) that outlines the key factors the Board takes into consideration in setting Executive KMP reward and the strategic drivers of pay at South32. It is important that reward levels fairly reflect the responsibilities and contribution of the Executive KMP and that outcomes are aligned to performance and the delivery of TSR. As a result, a meaningful portion of our Executive KMP remuneration is at risk, contingent on challenging individual and Company performance measures. Target Remuneration, as outlined below, assumes on-target performance for the STI and considers the difficulty of achieving LTI given the performance hurdles. The figures reflected in the diagram below are therefore based on the STI paid at 100 per cent of target and the LTI vesting at 60 per cent of face value (see page 84 for details on face value). Based on these principles, annual Target Remuneration for Executive KMP as at 30 June 2023 is illustrated in Diagram 1.3.

FY23 Target remuneration relative to peer groups (unaudited) We have operations and offices on six continents and compete for talent in a global pool. The diagrams below illustrate the measured approach we have adopted in positioning CEO fixed remuneration and Target Remuneration for FY23 compared to relevant benchmarks, being the ASX peer group and the global mining peer group (see page 85). CEO fixed remuneration is comparable to the median for both peer groups. CEO Target Remuneration is aligned to the upper quartile for the ASX peer group, but below the global mining peer group median. Diagram 1.4 – CEO fixed remuneration vs. Peers Diagram 1.5 – CEO Target Remuneration vs. Peers 3,000 0 0 0 $ A ’ 2,000 1,000 0 South32 1,906 15,000 10,000 0 0 0 $ A ’ 5,000 0 ASX Peers Global Mining Peers ASX Peers Global Mining Peers South32 Median Upper and lower quartiles South32 6,481 86 GOVERNANCE Range of possible remuneration outcomes As actual Company and individual achievement over the performance period determines reward outcomes, the amount of pay received by Executive KMP each year will vary. Diagram 1.6 illustrates the range of possible remuneration outcomes for the CEO, based on three performance outcome scenarios: minimum, target and maximum. While the figures in Diagram 1.6 and explanation are for the CEO, similar analysis can be undertaken for other Executive KMP to assess the minimum and maximum range of pay outcomes. Diagram 1.6 – Range of CEO remuneration outcomes (A$’000) Minimum 1,906 1,906 (all reward at risk is forfeited) Target 1,906 1,144 1,144 2,287 6,481 (71% at risk) Maximum 1,906 1,715 1,715 3,812 9,148 (79% at risk) 0 2,000 4,000 6,000 8,000 10,000 Fixed remuneration STI (cash) STI (deferred rights) LTI In the Minimum scenario, no STI or LTI is paid. The CEO would receive fixed remuneration, inclusive of superannuation, of A$1.906 million. Target outcomes would be achieved where the business meets the challenging STI performance hurdles, resulting in STI being paid at target levels (67 per cent of maximum opportunity, or 120 per cent of fixed remuneration, with half deferred into rights) and 60 per cent of the rights granted under the LTI vesting. To deliver a Maximum outcome for the STI (i.e. 180 per cent of fixed remuneration, with half deferred into rights), South32 would need to achieve the stretch targets for every metric in the Business Scorecard. For the LTI to vest in full, over the four-year performance period: – The South32 TSR would need to meet or exceed the TSR of the company at the 75th percentile in the EMIX Global Mining Index constituent group; – The South32 TSR would need to exceed the MSCI World Index by 23.9 per cent; and – The Board would need to assess performance against both strategic measures as outstanding. Deferred STI and LTI in the Target and Maximum scenarios do not incorporate future share price movements. Fixed remuneration for FY23 On 1 September 2022, Graham received an increase to fixed remuneration of five per cent from A$1,815,000 to A$1,906,000. This was his second increase in fixed remuneration since commencing in role in 2015. Katie, Jason and Noel received fixed remuneration increases of between five and six per cent. Fixed remuneration increases for Executive KMP aligned with the increases applied to the broader workforce in the relevant geographies (five per cent in Australia and six per cent in South Africa).

The overall STI outcome is determined by assessing three key inputs: the Business Scorecard, the Business Modifier and individual performance and behaviours. The Business Scorecard includes a balanced range of challenging measures that consider both our financial and non-financial performance, and help our Executive KMP focus on outcomes that are within their control and a priority for the year. The Business Modifier considers overall business outcomes or other factors that are not specifically contemplated in the Business Scorecard. The Business Modifier may be applied to Executive KMP on an individual or group basis, having regard to the perspectives of stakeholders including employees, shareholders and communities. Together, the Business Scorecard and the Business Modifier determine the South32 Business Outcome. Individual performance is measured based on delivery against the relevant operations’, projects’ or functions’ business plans. Our people are also assessed on demonstrated behaviour aligned to our values (i.e. both on what is achieved and how it is achieved). What this means in practice Including STI performance measures that are within the control of our executives means that the Business Scorecard outcomes will not always mirror underlying South32 financial outcomes. However, the Board has designed the STI, including the use of the Business Modifier and individual outcomes, so that executives are rewarded for delivering strong performance across areas within their control, taking into account overall business performance and shareholder experience. Diagram 1.8 demonstrates the approach to STI Outcomes applied by the Board over the past five years.

The Board recognises this significant safety event in our STI through the Business Modifier which adjusts the overall Business Scorecard outcome (see page 91). Table 1.5 reflects performance against our stated Business Scorecard measures. Table 1.5 – FY23 Business Scorecard outcomes Scorecard measure Sustainability Safety(1): Target 28.3% At least 80 per cent senior leader attendance at the LEAD Safely Every Day workshops and coaching sessions. A reported significant hazard frequency of 55. Ensure 90 per cent of significant event investigations are completed and signed off within the allocated timeframe. Ensure 90 per cent of significant event actions are completed on time. Complete a deep dive review of 20 selected material risks across all operations. A 20 per cent reduction in lost time injury frequency (LTIF) against the baseline. A 10 per cent reduction in TRIF from the FY22 baseline. Performance Outcome Zero Target Maximum 28.7% Good as assessed against the stated Business Scorecard measure, but prior to the Business Modifier adjustment. FY23 LEAD Safely Every Day program senior leader attendance was 99 per cent. The significant hazard frequency for the period was 92 which exceeded target. 89 per cent of significant event investigations were completed and signed off within the allocated timeframe. 95 per cent of significant event actions were completed on time. 24 material risk deep dives were completed. LTIF reduced by 30 per cent compared to the FY22 baseline. TRIF increased by 11 per cent compared to the FY22 baseline. Health(1): Poor A 20 per reduction in potential material exposures above 200 per cent of the Occupational Exposure Limit (OEL) compared to the revised FY22 baseline. Develop and implement a project pipeline to continue to reduce potential material exposures in excess of 200 per cent of OEL by FY24. Potential material exposures above 200 per cent of the OEL increased by 1.1 per cent compared to the revised FY22 baseline. The pipeline of FY24 projects aims to reduce potential exposures in excess of 200 per cent of OEL by 28 per cent compared to the FY23 outcome. Community(1): Excellent Implement social investment plans on time and on budget. FY23 social investment was delivered to plan. Increase the proportion of social investment allocated to strategic investment by 10 percentage points up to a maximum of 90 per cent of the social investment budget. Implement at least one new strategic multi-year social investment with targets that support climate, biodiversity or just transition related outcomes. Develop economic development plans which include local employment and procurement targets at all operations. 90 per cent of social investment was allocated to strategic investments (up 8 percentage points from 82 per cent in FY22). Two strategic investments commenced in FY23; a just transition strategic investment at Worsley Alumina and a biodiversity strategic investment in Australia with the Australian Wildlife Conservancy. Economic development plans were established for all operations, which include local employment and procurement targets. Risk management: Good Maintain risk routines at more than 95 per cent compliance with scheduled work. Increase the percentage of well controlled risks. Achieve 90 per cent compliance with the risk based assurance plan. Risk routines averaged 95 per cent compliance to scheduled work in FY23. The percentage of the risk profile reported as 'requires significant improvement' was on target. 96 per cent of the combined assurance plan was delivered to schedule. Water performance(1): Fair Deliver contextual water target milestones, and achieve the FY23 target water use efficiency outcome as defined within the Sustainability Linked Loan framework. The contextual water target for Hillside Aluminium was met. Targets at the remaining operations remained on track. FY23 water efficiency targets were met. However, the current identified pipeline of projects to achieve a 10 per cent improvement in water efficiency by FY27 compared to the FY21 baseline fell short of the required trajectory.

(5) Further information on this scorecard measure can be found in our Sustainable Development Report at www.south32.net. 90 GOVERNANCE 1B FY23 Business Modifier The Business Modifier is an integral component of the STI that considers overall business outcomes or other factors that are not specifically contemplated in the Business Scorecard, such as: – Significant safety or environmental events; – The shareholder experience; – Unexpected material external events, including the impact of a global pandemic or a significant disruption to global trade; – Significant reputational issues; and – An assessment of risk, culture or any other item that the Board considers appropriate. The Business Modifier, based on Board discretion, adjusts the overall Business Scorecard outcome so that STI outcomes reflect business performance, including both what has been delivered and how it has been achieved. The outcome may be positive or negative, and may be applied to Executive KMP on an individual or a group basis depending on the factors under consideration. In FY23, the Board primarily focused on two matters when considering the application of the Business Modifier for Executive KMP. The first was the loss of two of our colleagues, Mr Cristovão Alberto Tonela and Mr Alfredo Francisco Domingos João. Nothing is more important than the health, safety and wellbeing of our people. We will continue to work to improve our safety performance through our multi-year Safety Improvement Program that commenced in FY22. The program consists of four workstreams and was designed with the aim of enhancing our safety culture, and by changing mindsets and behaviours, achieving a step change in our safety performance. As part of the Safety Improvement Program's focus on shifting mindsets through leadership, we conducted our LEAD Safely Every Day training for senior leaders, managers, superintendents and supervisors across all operations and functions. This comprised workshops, learning assignments and individual coaching, with 1,322 leaders having commenced the capability training, and 247 leaders having completed it by 30 June 2023. In addition, we have updated our risk guidance documentation and conducted risk training for our risk and control owners. We have also finalised our internal safety standard to introduce the Safety System of Work that includes the new requirements for safety-critical equipment and process safety management. We have improved and extended our Contractor Management System of Work for our significant contractor workforce and have extended this into relevant functional departments in addition to operations. In FY24, we expect to launch a dedicated monitoring tool to better embed contractor management performance and to strengthen compliance with health and safety, and risk management requirements. More information on our safety initiatives, including our contractor management system of work, can be found in the Sustainable Development Report at www.south32.net. The second matter was the non-cash impairment expense for the Taylor Deposit recognised in our FY23 financial results which reflected the impact of delays due to COVID-19, the significant dewatering requirements and inflationary market pressures. The Board considered this when determining the negative overall Business Modifier for the CEO. Table 1.6 outlines the negative Business Modifiers the Board applied to the Business Scorecard for each member of Executive KMP. The different adjustments for the Executive KMP is intended to reflect the level of accountability each of them had in respect of the matters outlined above. Table 1.6 – Application of the Business Modifier by the Board (multiplier applied to the Business Scorecard outcome) CEO COO Africa and Colombia Other Executive KMP Modifier for FY23(1) -25% -20% -10% -5% FY22(2) -20% -20% -10% -10% -5% Modifier applied in previous years FY21 -20% -20% -5% FY20 -30% -30% -15% FY19 No Business Modifier applied (1) In FY23, the Board decided to apply a Business Modifier of -10 per cent for J Economidis, and a Business Modifier of negative five per cent for K Tovich and S Sibenaler. (2) In FY22, the Board decided to apply a Business Modifier of -20 per cent for the Chief Operating Officer Africa at the time of the fatality, a Business Modifier of -10 per cent for J Economidis and N Pillay, and a Business Modifier of negative five per cent for K Tovich. 91 SOUTH32 ANNUAL REPORT 2023 REMUNERATION REPORT CONTINUED 2 FY23 individual performance Our Board considers the individual scorecard outcomes for Executive KMP with regard to what was delivered, as demonstrated in the performance of each member of Executive KMP’s portfolio, and how it was delivered, which considers leadership behaviours aligned to our values, risk framework and governance processes. The board recognises Graham's outstanding leadership in delivering South32's purpose and strategy, but believes an individual outcome of 100% combined with the application of the Business Modifier is appropriate for FY23. Individual outcomes applied to the other Executive KMP reflected the performance outcomes in their areas of accountability and development in their respective roles. These outcomes ranged from 85 per cent to 140 per cent, as indicated in Table 1.7 below. 3 Overall FY23 STI outcome Overall STI outcomes for FY23 are determined through our Board’s assessment of the business and individual outcomes, as outlined in Table 1.7.

The deferred rights remain subject to continued service with the Group. (2) K Tovich ceased to be a member of Executive KMP on 31 March 2023. Details in the above table are for her period as a member of Executive KMP. (3) S Sibenaler was appointed as a member of Executive KMP on 1 April 2023. Details in the above table are for her period as a member of Executive KMP. S Sibenaler's individual outcome for the nine months in her prior role as Vice President Finance, which is not reflected in the table, was 120 per cent. 92 GOVERNANCE Long-term Incentive FY20 LTI and Management Share Plan (MSP) Performance award Our FY20 LTI award was tested for vesting subject to service and performance conditions to 30 June 2023. This award is subject to TSR performance conditions over four years, with two-thirds measured with reference to a global mining sector index (the IHS Markit Global Mining Constrained Weights Index with additional constraints by sector) and one third with reference to a world index (the MSCI World Index). The four-year period for this award was from 1 July 2019 to 30 June 2023. Jason and Noel were granted the FY20 MSP Performance award prior to their appointments as members of Executive KMP. This award has the same performance and vesting conditions as our FY20 LTI award. For the LTI and MSP Performance awards to vest in full, they needed to outperform both indices by at least 23.9 per cent over the four- year performance period (equivalent to 5.5 per cent per annum cumulative). Given that our TSR failed to meet the threshold level of performance required against both comparator indices (see Diagram 1.9 and Table 1.8), these awards lapsed in full in August 2023.

FY21 MSP Retention award Although South32 does not offer MSP Retention awards to permanent members of the Lead Team, including those that are Executive KMP, when individuals are promoted internally to Lead Team roles, they retain any unvested MSP awards that may vest while they are members of KMP. Sandy, Jason and Noel were granted FY21 MSP Retention awards prior to their appointments as permanent members of the Lead Team. As the service-based condition of these awards was met, our Board approved these awards to vest in full in August 2023. The structure of the MSP is detailed on page 102. 93 SOUTH32 ANNUAL REPORT 2023 REMUNERATION REPORT CONTINUED Summary of LTI outcomes in FY23 Table 1.9 – South32 LTI awards vested or lapsed/forfeited Executive KMP Award Number of rights granted Number of rights vested Number of rights lapsed/ forfeited Value at grant(1) (A$’000) Value lapsed/ forfeited(2) (A$’000) Value of share price movement(3) (A$’000) Value at vesting(4) (A$’000) G Kerr K Tovich S Sibenaler J Economidis N Pillay FY20 LTI FY20 LTI FY21 MSP Retention FY20 MSP Performance FY21 MSP Retention FY20 MSP Performance FY21 MSP Retention 1,696,261 517,133 23,762 155,763 99,009 135,708 86,262 - - 23,762 - 99,009 - 86,262 1,696,261 517,133 - 155,763 - 135,708 - 5,445 1,660 48 500 200 436 174 5,445 1,660 - 500 - 436 - - - 41 - 172 - 150 - - 89 - 372 - 324 (1) ‘Value at grant’ is the number of rights granted multiplied by the grant determination price in June 2019 of A$3.21 (for the FY20 LTI/FY20 MSP Performance) and June 2020 of A$2.02 (for the FY21 MSP Retention), based on the volume weighted average price (VWAP) of South32 Limited shares traded on the ASX over the last 10 trading days in June of the respective year.

LTI granted in FY23 FY23 LTI Plan Each year we grant performance rights to our Executive KMP. Our FY23 LTI Plan awards, which were granted in December 2022, have a four-year performance period and are subject to performance hurdles (see page 84). Shareholders approved, under ASX Listing Rule 10.14, the grant of rights for the CEO at the AGM on 27 October 2022. FY23 MSP award Sandy was granted awards under the MSP in December 2022 prior to her appointment to the Lead Team and before she became a member of Executive KMP. The structure of the MSP is detailed on page 102.

(2) The target value considers the difficulty of achieving performance hurdles. (3) The number of awards granted to Executive KMP in December 2022 is calculated by dividing the face value by the VWAP of South32 Limited shares traded on the ASX over the last 10 trading days of June 2022, being A$4.08. The fair value at grant for accounting purposes, as calculated by an external provider, was A$2.37 per right for the FY23 LTI and FY23 MSP Performance awards and A$3.85 per right for the FY23 MSP Retention award. (4) Fixed remuneration for N Pillay used to determine his FY23 LTI award was converted to A$ using an exchange rate of AUD: ZAR 11.11. 94 GOVERNANCE FY23 LTI Strategic Measures Performance Update In FY22 we introduced two strategic measures, with a total weighting of 20 per cent of our LTI grant, to directly link executive remuneration to our approach to climate change and the transition of our portfolio towards the commodities critical for a low-carbon future. Vesting outcomes for the strategic measures will be determined by the Board following the end of each four-year performance period (e.g. on 30 June 2026 for the FY23 LTI award), based on our ability to make material progress in these areas, while aiming to protect and create shareholder value as we navigate this business-critical transformation. The Board’s rationale in assessing performance and determining the vesting outcome for each measure will be clearly articulated and shared with shareholders following the Board’s assessment. Table 1.11 below summarises the progress made against each four-year strategic measure during FY23. Table 1.11 – Strategic Measures update for FY23 Measure Climate change FY23 progress against Measure We have announced plans to reduce our operational greenhouse gas emissions (Scope 1 and 2) by 50 per cent between FY21 and 2035, by implementing our decarbonisation framework, which includes: – The advancement of conceptual projects through our capital investment tollgates, and the successful commissioning of identified emissions reduction projects; – The ongoing assessment of new technologies and alternative energy sources; and In FY23(1), we have continued to mature and accelerate our planned decarbonisation programs to support our medium-term target and long-term goals. Key milestones included: – Commencing the conversion of Worsley Alumina’s first coal-fired boiler to natural gas, and progressing decarbonisation studies including mud washing, waste heat to digestion, and coal-alternative steam supply; – Converting 18 per cent of Hillside Aluminium pots to AP3XLE energy efficiency technology and progressing studies to transition the smelter's energy source from coal-based power to secure, reliable and affordable low-carbon energy in the medium-term; – Continued participation and direct investment in – Progressing the commercial scale pilot of CSIRO ventilation air methane technology research and development partnerships. into feasibility at Illawarra Metallurgical Coal; Consistent with our purpose, we will work to provide a just transition towards net zero in a way that supports our people, local communities and other stakeholders. – Transitioning Sierra Gorda to 100 per cent renewable energy; – Leading the Electric Mine Consortium’s infrastructure workstream and contributing by trialling light electric vehicles at Cannington; and – Embedding our just transition guiding principles into our environment and climate change standard and our social performance standard. Portfolio management We are planning to further reshape our portfolio and increase our exposure to the commodities critical to a low-carbon future by: – Building a high-quality portfolio of greenfield and brownfield exploration and development options; In FY23, we have continued to make progress in this transformative area. Key milestones included: – Embedding our recent investments in Sierra Gorda copper and our expanded low- carbon aluminium capacity, increasing aluminium production by 14 per cent and base metals by 17 per cent; – Optimising our existing portfolio by responsibly – Progressing multiple exploration programs as we continued work to discover our transferring ownership of non-core operations or transitioning them to closure; – Developing or acquiring operations which are cash generative through the cycle, improving the overall quality of our business; and next generation of base metals mines; – Consolidating our position in Argentina’s highly prospective San Juan province by exercising our earn-in right with Minsud Resources for 50.1 per cent of the Chita Valley copper exploration prospect and acquiring an interest in Aldebaran Resources; – Commencing our largest greenfield exploration program at our 100 per cent-owned – Maintaining discipline by adhering to our proven Roosevelt project in Alaska, targeting copper and zinc mineralisation; capital management framework. – Completing the sale of four non-core royalties, unlocking further latent value in our portfolio; and – Progressing exploration for copper, in additional to zinc, lead and silver at Hermosa's Peake prospect. In addition, permit applications have been advanced during the last 12 months to allow for testing of the Flux Prospect, a high priority target with similarities to the Taylor Deposit.

These are rights to receive fully paid ordinary shares in South32 Limited (or at the Board’s discretion, a cash equivalent amount) subject to meeting specific performance and vesting conditions. As the rights are an element of remuneration, no amount is payable by employees to be allocated the rights. If the rights vest, no consideration or exercise price is payable for the allocation of shares. As rights are automatically exercised on vesting, they do not have an expiry date. Rights carry no entitlement to voting, dividends or dividend equivalent payments. Unless our Board determines otherwise: – Resignation or termination for cause: all unvested rights lapse; – Death, serious injury, disability or illness that prevents continued employment or total permanent disability: all Cessation of employment unvested rights vest immediately; and – Other circumstances, generally: • Deferred STI awards: all unvested rights vest immediately; • LTI and MSP Performance awards: all unvested rights are pro-rated and the reduced portion remains on foot and eligible for vesting in the ordinary course, subject to any applicable performance hurdles; and • MSP Retention awards: all unvested rights are pro-rated and the reduced portion vests immediately. Where awards are pro-rated, the remaining portion lapses. Change of control Our Board can determine the level of vesting (if any) having regard to the portion of the vesting period elapsed, performance to date against any applicable performance conditions and other factors they deem appropriate. Our Board can reduce or clawback all vested and unvested STI and LTI awards in certain circumstances so that executives do not obtain an inappropriate benefit. These circumstances are broad, and can include: Malus and Clawback – An executive engaging in misconduct; – A material misstatement of our accounts that results in vesting; – Behaviours of executives that bring South32 into disrepute; – A significant unexpected or unintended consequence or outcome; and – Any other factor our Board deems justifiable. Rights to participate in new issues A participant cannot take part in new issues of securities in relation to their unvested rights. However, the relevant plan rules include specific provisions dealing with rights issues, bonus issues and corporate actions, and other capital reconstructions. 96 GOVERNANCE Non-Executive Director remuneration Components of our reward for FY23 Component Board Fees Committee Fees Travel Allowance We pay Committee fees to recognise the additional responsibilities associated with participating on a Board Committee. The why As a global company, it’s important that we offer competitive Non- Executive Director fees to help us attract the appropriate level of experience from a diverse global pool. Our Board fees reflect the size, complexity and global nature of our business and acknowledge the responsibilities of serving on our Board. To preserve the independence of our Non-Executive Directors, their remuneration does not have an ‘at risk’ element. The how Board fee inclusive of superannuation. We pay a fixed fee to our Board Chair for all responsibilities, including participation on any Board Committees. Other Non-Executive Directors receive Committee Chair and member fees (where applicable). Our Board meetings are ordinarily held in Australia, South Africa and North and South America (see page 71 for more details). Site visits are also an important part of our usual Board program, giving Directors: – A better understanding of workplace culture through interactions with site-based employees; – An improved understanding of local and operational risks; – A chance to participate in continuous education; and – On-the-ground experience. As these meetings (site visits and other engagements) take time and commitment, particularly if they are in remote locations, we provide our Non-Executive Directors with a travel allowance. For air travel to a Board commitment that is greater than three hours but less than 10 hours to the destination, a one-off allowance of A$5,000 per trip applies. Where air travel is greater than 10 hours to the destination, the allowance per trip is A$10,000. The travel allowance is only paid where travel is undertaken and does not apply to domestic travel to a regularly scheduled Board meeting. Fee Pool The maximum aggregate amount we can pay our Non-Executive Directors remains at A$3.9 million per annum (fee pool). We will always seek shareholder approval before making any changes to this pool. Minimum shareholding requirement Each Non-Executive Director is required to accumulate a minimum shareholding level of one year’s Board fees within a reasonable period. See page 102 for shareholdings of our Non-Executive Directors. FY23 Non-Executive Director fees We review fees every year and may get external advice to help us do so. We based the review of FY23 fees on data provided by external consultants. This resulted in a three per cent increase to Board fees for the Chair and other Non-Executive Directors from 1 September 2022, which were the first increases to Board fees since 1 September 2019. The table below outlines the fee levels for FY23. There will be no increase to Non-Executive Director fees in FY24.

The Board has confidence in the integrity of the reward framework, the core elements of which have remained unchanged since demerger, and believes it incorporates the necessary flexibility to reward our Executive KMP for performance that is aligned with the interests of stakeholders. Fixed remuneration The Board approved increases to the fixed remuneration of Executive KMP to maintain fixed remuneration at competitive levels in alignment with our reward framework (see page 84). These align with the increases applied to the broader workforce in the relevant geographies (four and a half per cent in Australia and six per cent in South Africa) (see Table 1.14). Table 1.14 – Fixed remuneration for Executive KMP in FY24, effective 1 September 2023 Executive KMP G Kerr S Sibenaler J Economidis N Pillay(1) FY23 fixed remuneration (A$) 1,906,000 830,000 819,000 ZAR 8,190,000 FY24 fixed remuneration (A$) 1,991,000 867,000 856,000 ZAR 8,680,000 Increase % 4.5 4.5 4.5 6.0 (1) Fixed Remuneration for N Pillay is denominated in ZAR. Using an exchange rate of AUD:ZAR 11.96, FY24 fixed remuneration in A$ is A$725,750. Short-term incentive The structure of our STI plan will remain unchanged for FY24. However, we have adjusted the measures in our Business Scorecard and their respective weightings (refer Diagram 1.11 for the FY24 STI measures) to reflect the key focus areas of our Executive KMP and other Lead Team members in FY24. The adjustment will result in an increase in weighting towards Safety and Culture as well as Environment and Social measures whilst maintaining focus on the financial metrics. Further, we have narrowed our Strategic Delivery measure to focus on delivery of key Hermosa project milestones, with the 20 per cent weighting in the LTI capturing the delivery of our broader strategic milestones.

We will continue to measure our performance over a four-year period with 80 per cent assessed based on TSR performance relative to two comparator groups and 20 per cent assessed against two strategic measures, climate change and portfolio management, each with a 10 per cent weighting. Director Fees There will no increase to Non-Executive Director fees or change to the travel allowances in FY24. 99 SOUTH32 ANNUAL REPORT 2023 REMUNERATION REPORT CONTINUED Statutory disclosures Statutory remuneration table for Executive KMP In the following table, we have set out the statutory disclosures required under the Act and in accordance with the Australian Accounting Standards.

Any rights that do not vest will immediately lapse, hence there is no expiry date associated with the awards. (S) - Service only or (P) - Performance and Service conditions apply. As rights are subject to service and/or performance conditions, the minimum possible total value of rights granted under South32 equity plans for future financial years is nil and the maximum possible total value is the number of rights multiplied by the market price of South32 shares on the date of vesting. (2) Further details regarding each of the prior year equity grants are described in past South32 Annual Reports. (3) The fair value for awards granted in FY23 is the grant date fair value for accounting purposes being A$3.99 for the FY22 Deferred STI award, A$2.37 for the FY23 LTI award and MSP Performance award and A$3.85 for the FY23 MSP Retention award. Shareholders approved, under ASX Listing Rule 10.14, the grant of rights for the CEO at the AGM on 27 October 2022. (4) Rights that vested in FY23 converted to South32 ordinary shares for nil consideration on 26 August 2022. The South32 closing share price on this date was A$4.23. The vesting outcome for FY20 LTI awards, FY20 MSP Performance awards and FY21 MSP Retention awards scheduled to vest in August 2023 is summarised on page 94. (5) The percentage is based on the maximum number of rights available to vest in FY23. (6) K Tovich ceased to be a member of Executive KMP on 31 March 2023. Closing balance is at this date. (7) S Sibenaler became a member of Executive KMP on 1 April 2023. Opening balance is as at this date. 101 SOUTH32 ANNUAL REPORT 2023            REMUNERATION REPORT CONTINUED Details of MSP and Transitional LTI awards Key terms and conditions of MSP and Transitional LTI awards are outlined below in table 1.17. For additional terms of the rights granted under the two plans, see Terms and conditions of rights awarded under equity plans on page 96. Table 1.17 – Key terms and performance conditions of awards(1) Award MSP Key Terms and Performance Conditions The MSP is our LTI plan for eligible management employees below Lead Team level. The Plan has two elements: – Retention rights with a three-year vesting and service period from 1 July to 30 June, vesting in August three years from grant provided employees remain employed in the Group(2); and – Performance rights with a four-year performance and service period from 1 July to 30 June, vesting in August four years from grant, subject to the same performance and vesting conditions as the LTI for Executive KMP (see page 84) for that year. There is no retesting if the performance condition is not met and any rights that don’t vest will immediately lapse/ be forfeited. Rights do not attract any entitlement to voting, dividends or dividend equivalent payments. Transitional LTI plan Katie, Sandy, Jason and Noel participated in the MSP prior to being permanently appointed to the Lead Team. When an executive is promoted to a role in the Lead Team, they move from the MSP (three-year retention rights and four-year performance rights) to the LTI plan for the Lead Team (four-year performance rights). The Transitional LTI is a one-off award that may be granted to address the potential shortfall in vesting after three years. These awards have the same TSR performance conditions as LTI awards granted in the same year except these awards have a three-year performance period. No Transitional LTI awards were granted or vested for Executive KMP during FY23. Details about Transitional LTI awards that are currently on foot are outlined above in table 1.16. Further details regarding Transitional LTI awards granted in earlier years are described in past South32 Annual Reports. (1) See page 84 for key terms of the LTI. (2) The retention rights are subject to a service condition. Performance hurdles are factored into the performance rights component of MSP awards. Shareholdings of KMP The minimum shareholding requirement for Executive KMP is summarised on page 85. For Non-Executive Directors, the valuation approach used to determine the minimum shareholding requirement of one year’s Board fee is the cost to the Non-Executive Director to acquire the shares, except for shares acquired at demerger which are valued based on the closing South32 Ltd share price on 18 May 2015 (A$2.05).

Where an accounting policy, critical accounting estimate, assumption or judgement is specific to a note, these are described within the note to which they relate. These policies have been consistently applied to all periods presented, except as described in note 3 New standards and interpretations. The consolidated financial statements of the Group for the year ended 30 June 2023 were authorised for issue in accordance with a resolution of the Directors on 7 September 2023. 1. Reporting entity South32 Limited is a for-profit company limited by shares incorporated in Australia with a primary listing on the Australian Securities Exchange (ASX), a standard listing on the London Stock Exchange (LSE) and a secondary listing on the Johannesburg Stock Exchange (JSE). The nature of the operations and principal activities of the Group are described in note 4 Segment information. 2. Basis of preparation The consolidated financial statements are general purpose financial statements which: – Have been prepared in accordance with the requirements of the Corporations Act 2001, Australian Accounting Standards and other authoritative pronouncements of the Australian Accounting Standards Board (AASB), International Financial Reporting Standards (IFRS) and other authoritative pronouncements of the International Accounting Standards Board (IASB); – Have been prepared on a historical cost basis, except for post-retirement assets and obligations, derivative financial instruments and certain other financial assets and liabilities which are required to be measured at fair value; – Are presented in US dollars, with all values rounded to the nearest million dollars (US$M or US$ million) unless otherwise stated, in accordance with ASIC Corporations Instrument 2016/191; – Present reclassified comparative information where required for consistency with the current year’s presentation; – Adopt all new and amended accounting standards and interpretations issued by the AASB and IASB that are relevant to the operations of the Group and effective for reporting periods beginning on or after 1 July 2022. Refer to note 3 New standards and interpretations for further details; and – Do not early adopt any accounting standards and interpretations that have been issued or amended but are not yet effective as described in note 3 New standards and interpretations. (a) Basis of consolidation The consolidated financial statements comprise the financial statements of the Group. A list of significant controlled entities (subsidiaries) at year end is contained in note 25 Subsidiaries. The financial statements of subsidiaries are prepared for the same reporting period as the parent entity, using consistent accounting policies. Changes in the Group’s interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions. (b) Foreign currency translation The functional currency of the majority of the Group’s operations is the US dollar, as this is assessed to be the principal currency of the economic environments in which they operate. Transactions denominated in foreign currencies are initially recorded in the functional currency using the exchange rate at the date of the underlying transaction. Monetary assets and liabilities denominated in foreign currencies are translated using the rate of exchange at year end. Exchange gains or losses on retranslation are included in the Consolidated Income Statement, with the exception of foreign exchange gains or losses on foreign currency provisions for closure and rehabilitation which are capitalised in property, plant and equipment for operating sites. (c) Key estimates, assumptions and judgements The preparation of the consolidated financial statements has required management to apply accounting policies and methodologies that are based on complex and subjective estimates, assumptions and judgements. Management based its estimates and judgements on historical experience and assumptions it believes to be reasonable and realistic based on the current environment. Actual results may differ from those reported in these statements due to the uncertainties that characterise the assumptions and conditions on which the estimates are based. Specific sources of uncertainty identified by the Group are set out on the following pages and/or together with the applicable note, as follows: Key estimates, assumptions and judgements Recognition of deferred taxes Uncertain tax matters Useful economic lives of assets Impairment of non-financial assets Closure and rehabilitation provisions Expected credit loss on credit-impaired financial assets note 6 note 6 note 11 note 13 note 15 note 19 In addition to the specific sources of uncertainty noted above, the following assumptions are considered pervasive to the financial statements as a whole: Climate change-related risks and opportunities The key estimates, assumptions and judgements made in these consolidated financial statements take into account the Group’s expectations of, and approach to, climate change-related risks, and are consistent with the Group’s reporting on climate-related matters. These expectations may affect the Group’s financial results and financial position in a number of ways, including the following: – The useful lives of assets, and therefore the depreciation and amortisation charged in the Consolidated Income Statement, may be impacted by changes in operational plans (refer to note 11 Property, plant and equipment); – Asset recoverable amounts may be affected due to changes in estimated future cash flows driven by, for example, changes in forecast commodity prices, operating costs, carbon prices and useful lives of assets (refer to note 13 Impairment of non- financial assets and note 19(b)(iii) Credit risk: Shareholder loan receivable from Sierra Gorda); – The commercial viability of exploration areas of interest may impact the recoverability of exploration and evaluation assets (refer to note 13 Impairment of non-financial assets); and – Timing and cost of closure and rehabilitation activities (refer to note 15 Provisions). The carrying amount of the associated deferred tax assets/ liabilities may change due to changes in estimates of the likely recovery of the related tax benefits. 110 FINANCIAL REPORT 2. Basis of preparation continued (c) Key estimates, assumptions and judgements continued Global transition to a low-carbon world While we are committed to the goals of the Paris Agreement, current global signposts continue to point towards a probable trajectory of at least 2°C warming which forms our base case(1) for global transition to a low-carbon world. Our base case directly informs our commodity demand outlook, forecast commodity prices and carbon prices. Any change in our base case may in turn impact our Ore Reserve estimates, mine plans, production volumes and future costs. The Group’s key estimates, assumptions and judgements with respect to transition risks and opportunities are based on the Group’s expectations and assessments at the date of this report, and actual results may differ. Government policies and market developments continue to drive uncertainty in commodity and carbon price outlooks, which may impact the Group’s approach to climate change and assumptions and judgements, which may in turn result in material changes to financial results and the carrying values of assets and liabilities in future reporting periods. Physical impacts of climate change The Group’s operations are located in regions that may experience extreme temperatures, bushfires, flooding and droughts. The Group has performed a baseline risk assessment of the physical impacts of climate change on its operated portfolio, with the assessment based on scenarios RCP4.5 and RCP8.5 as described by the Intergovernmental Panel on Climate Change (IPCC)(2). Longer term assets (including those that move into closure) are likely to face more significant challenges due to the expected severity of climate risks manifesting over longer timeframes. Climate change is likely to exacerbate the risks to water supply, storage and usage that we currently manage, particularly for operations in areas of water scarcity and other sensitive environmental aspects. The risk of the physical impacts of climate change were contemplated during the development of our life of operation plans (including closure estimates) and additional capital and/ or increases to operating costs have been incorporated into our forward-looking estimates when deemed appropriate. The Group’s ongoing analysis of reasonable alternative assumptions with respect to future climate conditions has not identified any additional indicator that the carrying value of assets cannot be recovered or that useful lives of assets will be shortened. The Group’s key estimates, assumptions and judgments with respect to the physical impacts of climate change are based on the Group’s expectations and assessments as at the date of this report, and actual results may differ. The high degree of uncertainty around the nature, timing and magnitude of weather events and long-term changes in climate patterns, as well as the Group’s continued physical risk assessment process and development of its direct adaptation and mitigation strategies, may result in material changes to financial results and carrying value of assets and liabilities in future reporting periods. Mineral Resources and Ore Reserves Estimating the quantity and/or grade of Mineral Resources requires the location, quantity, grade (or quality), continuity and other geological characteristics to be known, estimated or interpreted from specific geological evidence and knowledge, including sampling, in order to satisfy the requirement that there are reasonable prospects for eventual economic extraction. This process may require complex and difficult geological assessments to interpret the data. An Ore Reserve is the economically mineable part of the Measured and/or Indicated Mineral Resource that can be legally extracted, or where there is a reasonable expectation that approvals for extraction will be granted. In order to estimate Ore Reserves, consideration is required for a range of modifying factors, including mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental. When reporting Ore Reserves, the relevant studies, to at least a pre-feasibility level, must demonstrate that, at the time of reporting, extraction could be reasonably justified, including a consideration of forecast sales prices. With the exception of Sierra Gorda's mineral reserves, the Group reports Mineral Resources and Ore Reserves in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code), and the ASX Listing Rules (Chapter 5): Additional reporting on mining and oil and gas production and exploration activities. The Sierra Gorda estimates of mineral reserves are foreign estimates under the ASX Listing Rules and are not reported in accordance with the JORC Code. Refer to the Resources and Reserves section of this report for further information on the qualifying foreign estimates related to Sierra Gorda. Because the economic assumptions used to estimate the Ore Reserves change from period to period, and because additional geological data is generated during the course of operations, estimates of the Mineral Resources and Ore Reserves may change from period to period. The Group’s planning processes consider the impacts of climate change on its Ore Reserves, including assessments of operating costs and the impact of extreme weather events on the expectation of economic extraction. The Group may also include Exploration Targets in determining the recoverable amount of a cash generating unit (CGU) or an exploration area of interest. Similar to climate-change related risks and opportunities, changes in the Group's estimates of Mineral Resources and Ore Reserves, including estimates of exploration potential, may affect the Group’s financial results and financial position in a number of ways, including asset recoverable amounts, useful lives of assets, commercial viability of exploration areas of interest, timing and cost of closure and rehabilitation activities and the recovery of any associated deferred tax assets. (1) By contrast, our FY23 1.5°C scenario, which is primarily based on the International Energy Agency’s Net Zero Emissions 2050 scenario (IEA NZE), is utilised by the Group to assess the resilience of our portfolio under a rapid global transition. The IEA NZE sets out one credible pathway to achieving a 1.5°C outcome by 2050, providing a set of general assumptions on commodity demand drivers, scrap availability, material efficiency and carbon prices. (2) There are four Representative Concentration Pathways (RCPs) representing possible future greenhouse gas emissions and concentration scenarios. RCP4.5 equates to between 1.1°C and 2.6°C of warming by the end of the century. RCP8.5 equates to between 2.6°C and 4.8°C of warming by the end of the century. 111 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – BASIS OF PREPARATION CONTINUED 3. New standards and interpretations (a) New accounting standards and interpretations effective from 1 July 2022 The following new accounting standards and interpretations have been published and are effective for the year ended 30 June 2023: – Amendments to AASB 137 – Onerous Contracts, Costs to Fulfil a Contract; – Amendments to AASB 3 – Updating a reference to the Conceptual Framework; – Amendments to AASB 116 – Property, Plant and Equipment, Proceeds before Intended Use; and – Amendments to AASB 112 – International Tax Reform – Pillar Two Model Rules. The Group has reviewed these amendments and concluded that none have a significant impact on the Group. Refer to note 6(f) for further details of the impact on the Group as a result of the international tax reform and the related amendments to AASB 112. (b) New accounting standards and interpretations issued but not effective The following new accounting standards and interpretations have been published but are not yet effective for the year ended 30 June 2023: – Amendments to AASB 101 – Classification of Liabilities as Current or Non-current; – Amendments to AASB 10 and AASB 128 – Sale or Contribution of Assets between an Investor and its Associate or Joint Venture; – Amendments to AASB 7, AASB 101, AASB 108 and AASB 134 – Disclosure of Accounting Policies and Definition of Accounting Estimates; – Amendments to AASB 1 and AASB 112 – Deferred Tax related to Assets and Liabilities arising from a Single Transaction; – Amendments to AASB 16 – Lease Liability in a Sale and Leaseback; and – AASB 17 Insurance Contracts. The Group has reviewed these amendments and improvements and does not expect them to have a significant impact on the Group. The Group does not intend to early adopt any of the new standards or interpretations. It is expected that where applicable, these standards and interpretations will be adopted on each respective effective date. 112 FINANCIAL REPORT NOTES TO FINANCIAL STATEMENTS – RESULTS FOR THE YEAR This section focuses on the financial performance of the Group, covering both profitability and the resulting return to shareholders via earnings per share. 4. Segment information (a) Description of segments The operating segments (also referred to as operations) are organised and managed separately according to the nature of products produced. Group financing and income taxes are primarily managed on a Group basis and are not allocated to operating segments. Total assets and liabilities for each operating segment represent operating assets and liabilities which predominantly exclude the carrying amount of non-material equity accounted investments, cash, interest bearing liabilities, tax balances and certain other financial assets and liabilities. Revenue recognition The Lead Team (the chief operating decision makers) and the Board of Directors monitor the segment results regularly for the purpose of making decisions about resource allocation and assessing performance. Revenue is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. Revenue is not reduced for royalties and other taxes payable from Group production. The principal activities of each operating segment are summarised as follows: The following is a description of the principal activities from which the Group generates its revenue: Operating segment Principal activities Worsley Alumina Brazil Alumina Brazil Aluminium Hillside Aluminium Mozal Aluminium Sierra Gorda Cannington Hermosa Cerro Matoso Integrated bauxite mine and alumina refinery in Australia Integrated bauxite mine and alumina refinery in Brazil Aluminium smelter in Brazil Aluminium smelter in South Africa Aluminium smelter in Mozambique Copper mine in Chile Silver, lead and zinc mine in Australia Base metals exploration and development options in the United States Integrated laterite ferronickel mine and smelting complex in Colombia Metallurgical coal mines in Australia Illawarra Metallurgical Coal Australia Manganese Manganese ore mine in Australia South Africa Manganese Manganese ore mines in South Africa All operations are operated by the Group except Brazil Alumina, Brazil Aluminium and Sierra Gorda. (b) Segment results The segment information reflects the Group’s interest in subsidiaries and joint operations, as well as material equity accounted joint ventures on a proportional consolidation basis. The segment information includes non-IFRS financial measures. Segment performance is measured by Underlying EBIT and Underlying EBITDA. Underlying EBIT is profit before net finance income/(costs), income tax expense, royalty related tax expense and other earnings adjustment items. Underlying EBITDA is Underlying EBIT before depreciation and amortisation. Reconciliations of the underlying segment information to the statutory information included in the Group’s consolidated financial statements are set out in note 4(b)(i) Underlying results reconciliation, including joint venture adjustments which reconcile the proportional consolidation of the material equity accounted joint ventures back to their statutory equity accounting positions. The Group’s material equity accounted joint ventures are Sierra Gorda, Australia Manganese and South Africa Manganese, refer to note 26 Equity accounted investments. The Group separately discloses sales of group production from sales of third-party products and services because of the significant difference in profit margin earned on these sales. It is the Group’s policy that inter-segment transactions are made on an arm’s length basis. Group and unallocated items/eliminations represent group centre functions and consolidation adjustments. Revenue from the sale of commodities The Group primarily sells the following commodities: alumina, aluminium, copper, silver, lead, zinc, ferronickel, metallurgical coal and manganese ore. The sales of these commodities are considered to be performance obligations as they are the contractual promises by the Group to transfer distinct goods to customers. The transaction price allocated to each performance obligation is recognised as the performance obligation is satisfied. Satisfaction occurs when control of the promised commodity is transferred to the customer. For the sale of commodities, revenue is therefore recognised at a point in time, net of treatment and refining charges (where applicable). The majority of the Group’s sales agreements specify that title passes on the bill of lading date (the date the commodity is delivered to the shipping agent) and is assessed to be the point of time in which control over the commodity passes to the customer. For these sales, revenue is recognised on the bill of lading date. For certain sales, title passes and revenue is recognised when the goods have been delivered to the customer. For certain commodities, the sales price is determined on a provisional basis at the date of sale and adjustments to the sales price subsequently occur based on movements in quoted market or contractual prices up to the date of final pricing. The period between provisional invoicing and final pricing is up to 180 days. Revenue on provisionally priced sales is recognised based on the estimated fair value of the total consideration receivable. The revenue adjustment mechanism embedded within provisionally priced sales arrangements has the characteristics of a commodity derivative. Accordingly, the fair value of the final sales price adjustment is re-estimated continuously and changes in fair value are disclosed separately as ‘other’ revenue. In all cases, fair value is estimated by reference to forward market prices. Revenue from the provision of freight services The Group sells most of its commodities on either Free On Board (FOB) or Cost, Insurance, and Freight (CIF) Incoterms. In the case of CIF Incoterms, the Group is responsible for shipping services after the date at which control of the commodities passes to the customer at the port of loading. The provision of shipping services in these types of arrangements are a distinct service (and therefore a separate performance obligation) to which a portion of the transaction price should be allocated and recognised over time as the shipping services are provided. The Group also provides third party freight services which are recognised as the shipping service is provided. The Group does not separately disclose sales revenue from freight services as it does not consider this necessary in order to understand the impact of economic factors on the Group. 113 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – RESULTS FOR THE YEAR CONTINUED 4.

The equity in Ecora Resources PLC has been recognised as an investment in equity instruments designated at FVOCI. The variable consideration is payable if certain production and price-linked conditions are met prior to 2032, up to a maximum of US$15 million. The royalties were recognised as intangible assets with a nominal carrying value. On completion the Group recognised other income, net of transaction costs, of US$189 million (US$133 million post-tax) in the Consolidated Income Statement and was included in Group and unallocated items. Assets write-off On 23 August 2022, the Group announced that it would not proceed with an investment in the Dendrobium Next Domain project at Illawarra Metallurgical Coal following its consideration of recently completed study work and extensive analysis of alternatives considered for the complex. As a result of the decision in August 2022, the Group wrote off US$51 million (US$35 million post-tax) of costs previously capitalised in relation to the project which were recognised within expenses excluding finance costs in the Consolidated Income Statement. The write-off related to capitalised exploration and evaluation assets previously included in property, plant and equipment on the Consolidated Balance Sheet. Tax adjustments relating to the Sierra Gorda acquisition During the year, the Group recognised an income tax benefit of US$31 million relating to tax liabilities recognised on the acquisition of Sierra Gorda during FY22. The US$31 million benefit comprises a reassessment of US$17 million and a foreign exchange gain of US$14 million which is separately reported as part of exchange variations of tax balances. The tax adjustments relating to the Sierra Gorda acquisition have been excluded from the Group’s Underlying income tax expense on the basis that they do not relate to assessable income earned during its ownership. Vendor indemnity relating to the Sierra Gorda acquisition On 17 May 2023, Chilean Mining Tax reforms were passed by the Chilean Congress and subsequently enacted in August 2023. As part of the Group’s acquisition of Sierra Gorda during FY22, the Group has the right to claim an indemnity from the vendors for any mining tax changes enacted prior to December 2025. As a result of these changes the Group has recognised other income of US$48 million in the Group’s Consolidated Income Statement and a corresponding receivable of US$48 million from the vendors on the Group’s Consolidated Balance Sheet in relation to the indemnity.

The tax is deferred until earnings are repatriated from Brazil. Deferred tax is provided using the balance sheet liability method, providing for the tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for tax assessment or deduction purposes. The tax effect of certain temporary differences is not recognised, principally with respect to: – Temporary differences arising on the initial recognition of assets or liabilities (other than those arising in a business combination or in a manner that initially impacted accounting or taxable profit); – Temporary differences relating to investments and undistributed earnings in subsidiaries, joint ventures and associates to the extent that the Group is able to control its reversal and it is probable that it will not reverse in the foreseeable future; and – Goodwill. To the extent that an item’s tax base is solely derived from the amount deductible under capital gains tax legislation, deferred tax is determined as if such amounts are not deductible in determining future assessable income. A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the asset can be utilised. Deferred tax assets are reviewed at each balance sheet date and amended to the extent that it is no longer probable that the related tax benefit will be realised. Deferred tax assets and liabilities are offset when they relate to income taxes levied by the same tax authority and the Group has both the right and the intention to settle its current tax assets and liabilities on a net or simultaneous basis. (d) Unrecognised deferred tax assets and liabilities The composition of the Group’s unrecognised deferred tax assets and liabilities is as follows: US$M FY23 FY22 Unrecognised deferred tax assets Tax-effected losses(1) Mineral rights Impairment of investments in subsidiaries Closure and rehabilitation Depreciable assets Other temporary differences Total unrecognised deferred tax assets Unrecognised deferred tax liabilities Taxable temporary differences associated with investments and undistributed earnings in subsidiaries Total unrecognised deferred tax liabilities (1) Represents tax losses that have no expiry. 58 617 949 48 32 1 1,705 33 33 21 589 945 50 8 - 1,613 39 39 123 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – RESULTS FOR THE YEAR CONTINUED 6. Tax continued (e) Tax consolidation South32 Limited and its 100 per cent owned Australian resident subsidiaries have formed a tax consolidated group with effect from 25 May 2015. South32 Limited is the head entity of the tax consolidated group. Members of the group have entered into a tax sharing agreement in order to allocate income tax expense to the wholly-owned subsidiaries on a stand-alone basis. The tax sharing arrangement provides for the allocation of income tax liabilities between the entities should the head entity default on its tax payment obligations. The possibility of such a default is considered remote at the date of this report. Members of the tax consolidated group have also entered into a tax funding agreement. The group has applied its allocation approach in determining the appropriate amount of current taxes to allocate to members of the tax consolidated group. The tax funding agreement provides for each member of the tax consolidated group to pay or receive a tax equivalent amount to or from the head entity in accordance with their notional current tax liability or current tax asset. Such amounts are reflected in amounts receivable from or payable to the head entity in their accounts and are settled as soon as practicable after lodgement of the consolidated return and payment of the tax liability. (f) Future tax developments The Group continues to monitor the Organisation for Economic Co-operation and Development’s Two Pillar Solution in all countries in which the Group operates. Pillar One measures currently apply only to multinational enterprises that have a global turnover exceeding €20 billion and profitability exceeding 10%, and therefore does not apply to the Group. Pillar Two measures seek to introduce a 15% global minimum tax and will apply to the Group given its annual turnover exceeds the €750 million threshold. The Group notes that the UK Government has substantively enacted Pillar Two legislation in June 2023 and the Australian Government has committed to enacting the rules, however draft legislation is yet to be released. The Group has adopted the guidance contained in the IASB issued International Tax Reform - Pillar Two Model Rules, which amended IAS 12 Income Taxes, released in May 2023 and applied the mandatory temporary exception to recognise and disclose information about deferred tax assets and liabilities related to Pillar Two income taxes. The Group is currently evaluating the cash tax implications and other impacts of the Pillar Two model rules, and does not expect the impact on the Group to be significant. (g) Tax transparency report More detail of the Group’s tax outcomes, including country-by-country reporting is included in the 2023 Transparency and Payments to Government Report. Key estimates, assumptions and judgements Deferred tax Judgement is required in assessing whether deferred tax assets and certain deferred tax liabilities are recognised in the Consolidated Balance Sheet. Deferred tax assets are recognised only where it is considered more likely than not that they will be recovered, which is dependent on the generation of sufficient future taxable profits. Deferred tax liabilities arising from temporary differences in investments, caused principally by retained earnings held in foreign tax jurisdictions, are recognised unless repatriation of retained earnings can be controlled and are not expected to occur in the foreseeable future. Assumptions about the generation of future taxable profits and repatriation of retained earnings depend on management’s estimates of future cash flows. These depend on estimates of future production and sales volumes, commodity prices, climate change-related impacts, Mineral Resources and Ore Reserves, operating costs, closure and rehabilitation costs, capital expenditure, dividends and other capital management transactions. Uncertain tax matters Judgements are required about the application of the inherently complex income tax legislation in Colombia and Brazil. These judgements are subject to risk and uncertainty, hence there is a possibility that changes in circumstances will alter expectations, which may impact the amount of deferred tax assets and deferred tax liabilities recognised in the Consolidated Balance Sheet and the amount of other tax losses and temporary differences not yet recognised. Where the final tax outcomes are different from the amounts that were initially recorded, these differences impact the current and deferred tax provisions in the period in which the determination is made. Measurement of uncertain tax and royalty matters considers a range of possible outcomes, including assessments received from tax authorities. Where management is of the view that potential liabilities have a low probability of crystallising, or it is not possible to quantify them reliably, they are disclosed as contingent liabilities. 124 FINANCIAL REPORT 7.

Property, plant and equipment continued (a) Property, plant and equipment Property, plant and equipment is held at cost less accumulated depreciation and impairment charges. Cost is the fair value of consideration given to acquire the asset at the time of its acquisition or construction and includes the direct cost of bringing the asset to the location and condition necessary for operation and its estimated future cost of closure and rehabilitation. (b) Assets under construction When Ore Reserves are estimated and development of commercial production is approved, capitalised exploration and evaluation expenditure is reclassified to assets under construction. All subsequent development expenditure is capitalised and classified as assets under construction, provided commercial viability conditions continue to be satisfied. All assets included in assets under construction are reclassified to other categories in property, plant and equipment when the asset is available and ready for use in the location and condition necessary for it to be capable of operating in the manner intended. (c) Exploration and evaluation expenditure Exploration is defined as the search for potential mineralisation after the Group has obtained legal rights to explore in a specific area and includes topographical, geological, geochemical and geophysical studies and exploratory drilling, trenching and sampling. Evaluation is defined as the determination of the technical feasibility and commercial viability of a particular prospect. Activities conducted during the evaluation phase include the determination of the tonnage and grade and/or quality of the deposit, examination and testing of extraction methods and metallurgical or treatment process, surveys of transportation and infrastructure requirements, and market and finance studies. Exploration and evaluation expenditure (including amortisation of capitalised licence and lease costs) is charged to the Consolidated Income Statement as incurred except in the following circumstances, in which case the expenditure may be capitalised: – The existence of a commercially viable mineral deposit has been established as a result of a reasonable prospect for the eventual economic extraction; or – The exploration and evaluation activity is within an area of interest which was previously acquired as an asset acquisition or in a business combination and was measured at fair value on acquisition. In addition, drilling costs incurred at a producing mine for the purpose of improving confidence of the existing resource may be capitalised when the following criteria are satisfied: – The drilling occurs within the existing physical boundaries of the area defined as the resource; and – The drilling costs are incurred in resources which are economically recoverable. Capitalised exploration and evaluation expenditure considered to be a tangible asset is recognised as a component of property, plant and equipment at cost less impairment charges. Otherwise, it is recognised as an intangible asset (such as certain licence and lease arrangements). In determining whether the purchase of an exploration licence or lease is an intangible asset or a component of property, plant and equipment, consideration is given to the substance of the item acquired and not its legal form. Licences or leases purchased which allow exploration over an extended period of time meet the definition of an intangible exploration lease asset where they cannot be reasonably associated with a known Mineral Resource. (d) Other mineral assets Other mineral assets comprise: – Capitalised exploration and evaluation expenditure for areas now in production; – Development expenditure for areas now in production; and – Mineral rights acquired. In underground mines, when production and development activity occur concurrently, development activity is separated from production activity, and is capitalised as development expenditure in other mineral assets. Underground mine development activity includes the cost associated with gaining access to an ore deposit which gives rise to a substantive change in the future productive capacity of the mine. 128 FINANCIAL REPORT 11. Property, plant and equipment continued (e) Leases At inception of a contract, the Group assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Group recognises a right-of-use (ROU) asset and a lease liability at the lease commencement date. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability, plus any initial direct costs incurred and estimated future cost of closure or rehabilitation, less any lease incentives received. The ROU asset is subsequently measured at cost less accumulated depreciation, impairment and any adjustments for remeasurement of the lease liability. The corresponding lease liability is included within interest bearing liabilities. The lease liability is initially measured based on the value of lease payments not yet paid at the commencement date, discounted to present value using the interest rate implicit in the lease or, if that rate cannot be readily determined, the lessee’s incremental borrowing rate. The lessee’s incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow over a similar term, and with similar security, the funds necessary to obtain an asset of a similar value to the ROU asset in a similar economic environment. The lease liability is subsequently measured at amortised cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in a rate or an index or if the Group changes its assessment of whether it will exercise a purchase, extension or termination option. When the lease liability is remeasured, a corresponding adjustment is made to the carrying amount of the ROU asset, or is recognised in the Consolidated Income Statement if the carrying amount of the ROU asset has been reduced to nil. The nature of the Group’s leases predominantly relates to mining equipment and assets supporting the operations in line with the Group’s principal activities. Leased assets are pledged as security for the related lease liabilities. Short-term, low-value and variable leases The Group has elected not to recognise ROU assets and lease liabilities for short-term and low-value leases. Short-term leases are leases with a lease term of 12 months or less, while low-value leases are leases where the underlying asset is considered low value. Variable leases are leases with lease payments which are variable but do not depend on a rate or an index. The Group recognises the lease payments associated with these leases as an expense in the Consolidated Income Statement on a straight-line basis over the lease term. If variable leases have a fixed component, these would be recognised in the Consolidated Balance Sheet. Total cash outflows for lease obligations consist of US$98 million (FY22: US$99 million) for lease liabilities recognised in the Consolidated Balance Sheet and US$69 million (FY22: US$77 million) for short-term, low-value and variable leases recognised in the Consolidated Income Statement. (f) Depreciation and amortisation The carrying amounts of property, plant and equipment are depreciated to their estimated residual values over the estimated useful lives of the specific assets concerned. Estimates of residual values and useful lives are reassessed annually and any change in estimate is taken into account in the determination of remaining depreciation charges. Depreciation commences on the date of commissioning. The major categories of property, plant and equipment are depreciated on a units of production or straight-line basis using the estimated lives indicated below. However, where assets are dedicated to an operation or lease and are not readily transferable, the below useful lives are subject to the lesser of the asset category’s useful life and the life of the operation or lease. Category Useful life Buildings Land Plant and equipment ROU assets Mineral rights Capitalised exploration, evaluation and development expenditure 25 to 40 years straight-line not depreciated 3 to 30 years straight-line based on the shorter of the useful life or the lease term (straight-line) based on Ore Reserves on a units of production basis based on Ore Reserves on a units of production basis Key estimates, assumptions and judgements Useful economic lives of assets The useful lives of our property, plant and equipment are often dependent, either directly or indirectly, on the reserve life of the orebody to which they relate. Changes in economic assumptions used to estimate Ore Reserves and/or the timing of closure of operations, including the Group’s expectations with respect to climate change-related risks, may impact the estimated useful lives of the specific assets concerned. Refer to note 2(c) Key estimates, assumptions and judgements for further details regarding climate change-related risks and opportunities, and Mineral Resources and Ore Reserves as sources of estimation uncertainty. 129 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OPERATING ASSETS AND LIABILITIES CONTINUED 12.

(a) Goodwill Where the fair value of consideration paid for a business combination exceeds the fair value of the Group’s share of the identifiable net assets acquired, the difference is treated as purchased goodwill. Where the fair value of the Group’s share of the identifiable net assets acquired exceeds the fair value of consideration paid, the difference is immediately recognised in the Consolidated Income Statement. Goodwill is not amortised, however, its carrying amount is assessed annually against its recoverable amount. (b) Other intangible assets Amounts paid for the acquisition of identifiable intangible assets, such as software, licences and contract based intangible assets are capitalised at the fair value of consideration paid and are recognised at cost less accumulated amortisation and impairment charges. Identifiable intangible assets with a finite life are amortised on a straight-line basis over their expected useful life from when the asset is ready for use. The useful lives are as follows: Category Software and licences Contract based intangible assets Useful life 5 years up to 35 years The Group has no identifiable intangible assets for which the expected useful life is indefinite. 130 FINANCIAL REPORT 13. Impairment of non-financial assets In testing for indications of impairment and performing impairment calculations, assets are considered as collective groups and referred to as CGUs. Impairment tests are carried out annually for CGUs containing goodwill and when there is an indication of impairment or impairment reversal for all other CGUs. The Group uses discounted cash flow valuation ranges to assess whether there is an indicator of impairment or impairment reversal for its CGUs. For any resulting impairment testing, and for CGUs containing goodwill, the Group uses the higher of fair value less cost of disposal (FVLCD) and its value in use to assess the recoverable amount. If the carrying value of the CGU exceeds its recoverable amount, the CGU is impaired and an impairment loss is charged to the Consolidated Income Statement. Previously impaired CGUs are reviewed for possible reversal of impairment at each reporting date. Impairment reversals cannot exceed the carrying value that would have been determined (net of depreciation) had no impairment loss been recognised for the CGU. Goodwill is not subject to impairment reversal. For areas not yet in production, any mineral rights acquired, together with subsequent capitalised exploration and evaluation expenditure, are reviewed to determine the appropriateness of continuing to carry forward costs in relation to that area of interest. Once the technical feasibility and commercial viability of an area of interest are demonstrated, exploration and evaluation assets attributable to that area of interest are tested for impairment. The Group recognised the following net impairment for the year ended 30 June 2023: US$M Impairment Property, plant and equipment(1) ROU assets(1) Intangible assets Impairment reversal Property, plant and equipment(2) Total net impairment Note FY23 FY22 11 11 12 11 1,300 - - - 1,300 176 7 4 (42) 145 (1) FY23 relates to a US$1,300 million impairment of the Taylor Deposit within the Hermosa segment. FY22 relates to a US$183 million impairment included in Group and unallocated items in respect of Eagle Downs. This includes a US$176 million impairment of property, plant and equipment and a US$7 million impairment of ROU assets. (2) FY22 relates to a US$42 million impairment reversal included within the Brazil Aluminium segment. (a) Recognised impairments - 30 June 2023 Hermosa – Taylor Deposit In August 2018, the Group completed its acquisition of the Hermosa project located in Arizona, United States. The Hermosa project comprises the zinc-lead-silver sulphide deposit (Taylor Deposit), the manganese-zinc-silver oxide deposit (Clark Deposit) and a land package with the potential for further polymetallic and copper mineralisation (Land Package). In FY23, the Group advanced the feasibility study for the Taylor Deposit, completed a pre-feasibility selection study for the Clark Deposit and announced that the US Federal Permitting Improvement Steering Council, an independent federal agency, had confirmed the Hermosa project as the first mining project added to the FAST-41 process. Since acquisition, the fair value of the Taylor Deposit has been negatively impacted by delayed first production as a result of COVID-19 related restrictions and significant dewatering requirements, as well as capital cost escalation in line with industry-wide inflation. Recently completed study work confirmed that the Taylor Deposit and the Clark Deposit can be developed independently. As a result, the Group identified three separate areas of interest within the Hermosa project: the Taylor Deposit, the Clark Deposit and the Regional Land Package. On separation into three separate areas of interest, the Group allocated the carrying value of the previous single Hermosa area of interest to each of the newly identified and separate areas of interest. As a result of the study work to date, the Group identified an impairment indicator for the Taylor Deposit and recognised a resulting impairment of property, plant and equipment of US$1,300 million in FY23 within expenses excluding finance costs in the Consolidated Income Statement. The impairment of US$1,300 million includes US$1,049 million recognised in other mineral assets, US$119 million recognised in assets under construction and US$132 million recognised in exploration and evaluation. The recoverable amount of the Taylor Deposit was determined as US$482 million based on its FVLCD. 131 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OPERATING ASSETS AND LIABILITIES CONTINUED 13. Impairment of non-financial assets continued (a) Recognised impairments - 30 June 2023 continued Hermosa – Taylor Deposit continued The fair value measurement was categorised as a Level 3 fair value based on the inputs in the discounted cashflow valuation model (refer to note 19 Financial assets and financial liabilities). The recoverable amount was informed by inputs from the feasibility study in progress for the Taylor Deposit, including the expected technical performance of the deposit as well as expected capital and operating costs for the life of the operation. The determination of FVLCD was most sensitive to: – Zinc, lead and silver prices; – Pre-production capital expenditure; – Mineral Resource estimation; – Development approvals; and – Discount rate Zinc, lead and silver prices - The long-run zinc, lead, and silver prices, in real terms, used in the FVLCD determinations were within the following ranges: FY23 Zinc (US$/t) Lead (US$/t) Silver (US$/oz) Assumptions used 2,700 to 3,200 2,000 to 2,100 20 to 22 Pre-production capital expenditure – The calculation of FVLCD includes an estimate of pre-production capital to support the development of the Taylor Deposit to its nameplate capacity of up to 4.3 million tonnes per annum. Key inputs including steel, cement and electrical components are subject to uncertainties, including industry-wide inflation. Mineral Resource estimation - The Mineral Resource estimate of the Taylor Deposit is reported in accordance with the JORC Code, and the ASX Listing Rules (Chapter 5): Additional reporting on mining and oil and gas production and exploration activities. Refer to the Mineral Resources and Ore Reserves section of note 2(c) for further information on these estimates. Development approvals – Construction is planned to commence in late FY24, subject to a final investment decision for the Taylor Deposit. The addition of the Hermosa project to the FAST-41 process has reduced the expected timing of Federal environmental approvals and permits by approximately two years. A Record of Decision (RoD) to permit surface disturbance and additional tailings storage on unpatented land will require completion of the National Environmental Policy Act process with the United States Forest Service. The ramp-up to planned nameplate production could be impacted if the RoD is delayed as production will have to be slowed due to tailings capacity restrictions on patented lands. Discount rate - In determining the FVLCD, a real US$ post tax discount rate range of between 6 and 8 per cent was applied to discount future cash flows expressed in real terms. The following table illustrates the sensitivity of the recoverable amount of the Taylor Deposit based on a reasonably possible change in key assumptions. Owing to the complexity of the relationships between each key assumption, the analysis was performed for each assumption individually (all other assumptions held constant).

Impairment of non-financial assets continued (b) Recognised impairments - 30 June 2022 Eagle Downs Metallurgical Coal In October 2021, the Group announced the commencement of a process to investigate the potential divestment of our interest in the Eagle Downs Metallurgical Coal development option. In December 2021, as part of the negotiation for sale, the Group received non- binding offers from external parties which, in combination with the long-term market outlook for metallurgical coal demand and prices, resulted in the recognition of an impairment of US$79 million for the Eagle Downs area of interest. The impairment was recognised within expenses excluding finance costs in the Consolidated Income Statement. In April 2022, a preferred bidder withdrew from the negotiations and the Group revised its recoverable amount of the Eagle Downs area of interest to US$nil, bringing the total impairment recognised for the Eagle Downs area of interest in FY22 to US$183 million. The long-run metallurgical coal prices and exchange rates, in real terms, used as part of the Group’s FVLCD determinations at 30 June 2022 were within the following ranges as published by market commentators: FY22 Metallurgical coal (US$/t) Foreign exchange rates (A$ to US$) Assumptions used 135 to 175 0.71 to 0.80 The fair value measurement was categorised as a Level 3 fair value based on the inputs in the discounted cashflow valuation model in combination with the use of the market approach (refer to note 19 Financial assets and financial liabilities). In determining the FVLCD, a real US$ post tax discount rate range of between six and eight per cent was applied to discount future cash flows expressed in real terms. In addition to the impairment of ROU assets of US$7 million, the impairment of US$176 million for property, plant and equipment of Eagle Downs includes US$3 million recognised in land and buildings, US$7 million recognised in plant and equipment, US$102 million recognised in other mineral assets, US$51 million recognised in assets under construction, and US$13 million recognised in exploration and evaluation. Brazil Aluminium On 6 January 2022, the Group announced its decision to participate in a restart of the Brazil Aluminium smelter. The Group assessed the implications of the restart decision and reviewed the impact on the carrying value of the Brazil Aluminium CGU as at 31 December 2021. At 31 December 2021, the Group reversed the full impairment that was recognised when the smelter was placed on care and maintenance in 2015, limited to the carrying amount that would have been determined (net of amortisation and depreciation) had no impairment loss been recognised at such time. The recoverable amount remains significantly higher than the carrying amount recorded. The recoverable amount was based on the smelter’s FVLCD and was informed by the Group’s production profile and cost profile which were consistent with the Group’s commitments to long-term power agreements. The key assumptions used for commodity prices were comparable to market consensus forecasts and foreign exchange rates were aligned with forward market rates. The fair value measurement was categorised as a Level 3 fair value based on the inputs in the discounted cashflow valuation model (refer to note 19 Financial assets and financial liabilities). In determining the FVLCD, a real US$ post tax discount rate range of between six and eight per cent, and a country risk premium of two per cent, was applied to discount future cash flows expressed in real terms. The impairment reversal of US$42 million includes US$18 million recognised in land and buildings and US$24 million recognised in plant and equipment, both within property, plant and equipment. The impairment reversal was recognised within expenses excluding finance costs in the Consolidated Income Statement. In addition, the Group recognised indirect tax assets of US$77 million that had been expensed since the smelter was placed on care and maintenance in 2015. Refer to note 4(b)(ii) Significant items. 133 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OPERATING ASSETS AND LIABILITIES CONTINUED 13. Impairment of non-financial assets continued (c) Impairment test for CGUs containing goodwill For the purpose of impairment testing, goodwill has been allocated to CGUs that are expected to benefit from the synergies of the business combination and which represent the level at which management will monitor and manage the goodwill. The carrying amount of goodwill has been allocated to the following CGU: US$M Hillside Aluminium Total goodwill Note 12 FY23 139 139 FY22 139 139 The goodwill arose from the acquisition of Alusaf in Hillside Aluminium (Pty) Ltd and has been allocated to the Hillside Aluminium CGU which comprises the Hillside aluminium smelter. The recoverable amount of the Hillside Aluminium CGU was determined based on a FVLCD calculation and was categorised as a Level 3 fair value based on the inputs in the valuation technique (refer to note 19 Financial assets and financial liabilities). The impairment test for the Hillside Aluminium CGU indicated that no impairment was required. The determination of FVLCD was most sensitive to: – Production volumes; – Aluminium and alumina prices; – Foreign exchange rates; – Carbon pricing and timing; and – Discount rate. Production volumes – estimated production volumes are based on the life of the smelter as determined by management as part of its long-term planning process. Production volumes are influenced by production input costs such as electricity prices, jurisdiction based carbon pricing, and the selling price of aluminium. Aluminium and alumina prices, and foreign exchange rates – the ranges of aluminium prices, alumina prices and exchange rates, in real terms, used in the FVLCD determinations, together with the potential effect of using reasonably possible alternative assumptions on the recoverable amount, based on unfavourably changing these assumptions by 10 per cent whilst holding all other variables constant, are shown in the table below: FY23 Aluminium prices (US$/t) Alumina prices (US$/t) Foreign exchange rates (US$ to ZAR) Assumptions used 2,238 to 2,510 343 to 426 16.1 to 19.1 Impact on recoverable amount (US$M) (683) (214) (304) Carbon pricing and timing – in determining the FVLCD, the current jurisdiction enacted carbon price, in real terms, of ZAR186 to ZAR474 per tonne CO2-e (FY22: ZAR143 to ZAR150 per tonne CO2-e) is applied for the life of operation for Scope 1 and 2 emissions, net of operation specific abatement allowances. Discount rate – in determining the FVLCD, a real US$ post tax discount rate range of between six and eight per cent (FY22: range of between six and eight per cent), and a country risk premium of two per cent (FY22: two per cent) was applied to discount future cash flows expressed in real terms. The impairment test for the Hillside Aluminium CGU indicated that no impairment was required. At 30 June 2023 the carrying value approximates its recoverable amount. As such any material long-term unfavourable change in the aforementioned key assumptions could lead to the carrying value exceeding the recoverable amount. The relationships between each key assumption are complex, such that a change in one may cause a change in several other inputs. 134 FINANCIAL REPORT 13. Impairment of non-financial assets continued Key estimates, assumptions and judgements An assessment as to whether there is any indication of impairment and the calculation of a CGU’s recoverable amount requires management to make estimates and assumptions about expected production and sales volumes, commodity prices, foreign exchange rates, Mineral Resources and Ore Reserves, regulatory approvals, operating costs, closure and rehabilitation costs, future capital expenditure, allocation of corporate costs, jurisdiction-specific carbon prices and global carbon pricing. These estimates and assumptions are subject to risk and uncertainty. There is a possibility that changes in circumstances will alter these projections, which may impact the recoverable amount. In such circumstances, some or all of the carrying amount may be impaired or a previously recognised impairment charge may be reversed with the impact recognised in the Consolidated Income Statement. The key estimates and assumptions used in the assessment of impairment indicators are as follows: Future production Commodity prices and market traded consumables Exchange rates Discount rates Regulatory approvals Carbon prices Life of operation plans based on Mineral Resource and Ore Reserve estimates, economic life of smelters and refineries and, in certain cases, Exploration Targets and expansion projects, including future cost of production. Refer to note 2(c) Key estimates, assumptions and judgements for further details regarding Mineral Resources and Ore Reserves as sources of estimation uncertainty. Forward market and contract prices, and longer-term price estimates which includes an assessment of the impact carbon price assumptions might have. Forward market foreign exchange rates, and longer-term price protocol estimates. Risk-adjusted cost of capital and appropriate to the resource. Life of operation plans include assumptions associated with the successful application, and timing thereof, of ongoing and future regulatory approvals. Actual enacted schemes less allowable abatements, where applicable, and a long-term base case estimate of US$64 per tonne CO2-e (real) applied to all Scope 1 and 2 emissions from FY40 onwards. Where impairment testing is undertaken, a range of external sources are considered as further input to the above assumptions. Exploration and evaluation expenditure For areas not yet in production, acquired mineral rights, together with subsequent capitalised exploration and evaluation expenditure, require judgement to determine the likelihood of future economic benefits from future development, and whether sufficient data exists to indicate that, although a development in the specific area is likely to proceed, the carrying amount of the exploration and evaluation asset is unlikely to be recovered in full. When facts and circumstances suggest that the carrying amount exceeds the recoverable amount, an impairment test is required which may result in an adjustment to the carrying value of acquired mineral rights together with subsequent capitalised exploration and evaluation expenditure. At or before the final investment decision for a given area of interest, and once technical feasibility and commercial viability has been demonstrated, the Group assess the carrying value of that area of interest for impairment or, for an area of interest previously impaired, impairment reversal. 135 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OPERATING ASSETS AND LIABILITIES CONTINUED 13. Impairment of non-financial assets continued Key estimates, assumptions and judgements continued Climate change-related risks and opportunities The Group’s forecast commodity prices and other key assumptions represent management’s expectations on likely outcomes, with a base case estimation of at least 2°C warming. When assessing whether there is any indication of impairment or impairment reversal, management performs a sensitivity analysis by considering a range of possible scenarios, with no one scenario being conclusive in isolation. Our sensitivity analysis shows that our FY23 1.5°C scenario would result in an increased risk of impairment at the Hillside Aluminium and Illawarra Metallurgical Coal CGUs. The full costs and benefits of decarbonisation projects are included in the Group’s valuations when it has a high degree of confidence that a project will achieve an emissions reduction, which typically aligns with the related capital project being internally approved, or when it is critical for meeting regulatory licensing requirements. The Group’s valuations include the cost and benefit of initiatives necessary to meet its medium-term target to halve its operational greenhouse gas (GHG) emissions by 2035 compared to its FY21 baseline. ‘Target’ is defined as an intended outcome in relation to which we have identified one or more pathways for delivery of that outcome, subject to certain assumptions or conditions. The decarbonisation pathway to meet our goal of net zero GHG emissions by 2050 is not yet fully defined and, as such, the cost and benefit of all associated initiatives are not included in the Group’s valuations. ‘Goal’ is defined as an ambition to seek an outcome for which there is no current pathway(s), but for which efforts will be pursued towards addressing that challenge, subject to certain assumptions or conditions. The Group utilises an internal price on carbon to inform decision-making and valuations, based on actual enacted schemes less allowable abatements, where applicable, and a long-term base case estimate of US$64 per tonne CO2-e (real) applied to all Scope 1 and 2 emissions from FY40 onwards. In developing forecast global carbon prices, the Group considers policy and market-driven carbon prices as well as abatement costs, weighted across developed and developing countries. When assessing for impairment indicators, the Group has considered the sensitivity of operations to changes in carbon prices. The Group’s operations are not uniformly impacted by carbon prices. The impact is influenced by the amount of Scope 1 and 2 emissions the operation generates and the jurisdiction in which it operates, in combination with the respective life of operation plans. The Group’s CGUs with a higher carbon sensitivity include Worsley Alumina, Hillside Aluminium, Mozal Aluminium and Illawarra Metallurgical Coal. Previously impaired areas of interest and CGUs When assessing for impairment reversal indicators, the fundamental characteristics of previously impaired areas of interest and CGUs are relevant to their sensitivity to key estimates and assumptions. For previously impaired areas of interest and CGUs these include: – Areas of interest that are subject to ongoing study and evaluation, for example the Taylor Deposit at Hermosa; – CGUs with higher operating margins and with life of operation plans longer than 10 years which are less sensitive to short-term commodity prices and foreign exchange rates, for example Worsley Alumina; – CGUs with lower operating margins which are highly sensitive to movements in commodity prices and foreign exchange rates, for example South Africa Manganese; and – CGUs with higher operating margins, shorter life of operation plans and exposure to commodities that display greater price volatility, for example Australia Manganese. Mozal Aluminium The Group jointly controls Mozal Aluminium together with the Industrial Development Corporation of South Africa Limited and the Government of the Republic of Mozambique. Electricity supplied to Mozal Aluminium is generated by Hidroeléctrica de Cahora Bassa, a hydro-electric power generator, and supplied via Eskom, the South African state-owned entity which owns and operates South Africa’s national electricity grid. Eskom also provides back-up energy to Mozal Aluminium for periods when Hidroeléctrica de Cahora Bassa produces less than its contractual minimum supply of hydro-electric power. The Group is working with key stakeholders to extend the supply of power from Hidroeléctrica de Cahora Bassa for Mozal Aluminium beyond 2026. Although an extension and pricing of the existing arrangement with Eskom is uncertain, the Group has made a reasonable assumption that an extension to 2030 can be achieved on mutually acceptable commercial terms. Failure to extend the supply of power from Hidroeléctrica de Cahora Bassa will have a material impact on the recoverable amount of Mozal Aluminium. 136 FINANCIAL REPORT 14.

(a) Employee benefits Liabilities for unpaid wages and salaries are recognised in other creditors. Current entitlements to annual leave and accumulating sick leave accrued for services up to the reporting date are recognised in the provision for employee benefits and are measured at the amounts expected to be paid. Entitlements to non-accumulated sick leave are recognised when the leave is taken. The current liability for long service leave (for which settlement within 12 months of the reporting date cannot be deferred) is recognised in the current provision for employee benefits and is measured in accordance with annual leave described above. (b) Closure and rehabilitation The mining, extraction and processing activities of the Group normally give rise to obligations for site closure or rehabilitation. Closure and rehabilitation works can include facility decommissioning and dismantling, removal or treatment of waste materials, site and land rehabilitation. Provisions for the cost of each closure and rehabilitation program are recognised at the time that environmental disturbance occurs. When the extent of disturbance increases over the life of an operation, the provision is increased accordingly. Costs included in the provision encompass all closure and rehabilitation activity expected to occur progressively over the life of the operation and at, or after, the time of closure, for disturbance existing at the reporting date. Routine operating costs that may impact the ultimate closure and rehabilitation activities, such as waste material handling conducted as an integral part of a mining or production process, are not included in the provision. Costs arising from unforeseen circumstances, such as the contamination caused by unplanned discharges, are recognised as an expense and liability when the event gives rise to an obligation which is probable and capable of reliable estimation. The timing of the actual closure and rehabilitation expenditure is dependent upon a number of factors such as: the life and nature of the asset; the operating licence conditions; and the environment in which the operation operates. Expenditure may occur before and after closure, and can continue for an extended period of time depending on closure and rehabilitation requirements. 138 FINANCIAL REPORT 15. Provisions continued (b) Closure and rehabilitation continued Closure and rehabilitation provisions are measured based on the expected value of future cash flows, discounted to their present value and determined according to the probability of alternative estimates of cash flows occurring for each operation. Discount rates used are risk-free interest rates specific to the country in which the operations are located and the expected timing of the closure and rehabilitation expenditure. Material changes in country specific risk-free interest rates may affect the discount rates applied. The Group reviews its discount rates used periodically, with any corresponding change in the provision as a result of revising discount rates capitalised as an asset in the case of open sites or charged/(credited) to the Consolidated Income Statement in the case of closed sites. When provisions for closure and rehabilitation are initially recognised, the corresponding cost is capitalised as an asset, representing part of the cost of acquiring the future economic benefits of the operation. The capitalised cost of closure and rehabilitation activities is recognised in property, plant and equipment and depreciated accordingly. The value of the provision is progressively increased over time due to the effect of discounting unwind and inflation, creating an expense recognised in finance costs. Closure and rehabilitation provisions are also adjusted for changes in costs and estimates. Those adjustments are accounted for as a change in the corresponding capitalised cost, except where a reduction in the provision is greater than the depreciated capitalised cost of the related assets, in which case the carrying value is reduced to nil and the remaining adjustment is recognised in the Consolidated Income Statement. In the case of closed sites, changes to estimated costs are recognised immediately in the Consolidated Income Statement. Changes to the capitalised cost result in an adjustment to future depreciation. Adjustments to the estimated amount and timing of future closure and rehabilitation cash flows are a normal occurrence in light of the significant judgements and estimates involved. (c) Post-retirement employee benefits This relates to the provision for post-employment defined benefit pension and medical schemes. Refer to note 22 Pension and other post-retirement obligations. Key estimates, assumptions and judgements The recognition of closure and rehabilitation provisions requires judgement and is based on significant estimates and assumptions such as: – The requirements of the relevant local legal and regulatory framework; – The magnitude of possible contamination; – The timing, extent and cost of required closure and rehabilitation activity; and – Potential changes in physical and climate conditions. These uncertainties may result in future actual expenditure differing from the amounts currently provided. The Group’s expectations and approach in relation to climate change-related risks and opportunities are reflected in the estimates and assumptions noted above. For example, our base case estimation of at least 2°C climate-related warming impacts our life of operations plans, which in turn impacts assumptions regarding timing and cost of closure and rehabilitation activities. Physical impacts of climate change have been considered in the estimation of closure and rehabilitation costs, including timing of relinquishment based on the Group’s assessment to date. These estimates will continue to be refined as the Group progresses its assessment of physical risks and development of direct adaptation and mitigation strategies. The provision recognised for each site is periodically reviewed and updated based on the facts and circumstances available at the time. In addition to the uncertainties noted above, certain closure and rehabilitation activities may be subject to legal disputes and depending on the ultimate resolution of these disputes, the final liability for such matters could vary. If risk-free interest rates were decreased by 0.5 per cent (in real terms), the provision would increase by approximately US$261 million. 139 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – CAPITAL STRUCTURE AND FINANCING This section outlines how the Group manages its capital and related financing activities. 16.

On 14 April 2022, the Group completed the issuance of US$700 million of senior unsecured notes pursuant to Rule 144A and Regulation S of the United States Securities Act of 1933. The Group utilised the cash proceeds from the offering, together with cash on hand, for the repayment in full of the amounts drawn down under its acquisition bridge facility used to partly fund the acquisition of a 45 per cent interest in Sierra Gorda in FY22. The notes will pay interest on 14 April and 14 October each year at a rate of 4.35 per cent per annum and mature in 2032. All borrowings are initially recognised at their fair value net of directly attributable transaction costs. Subsequent to initial recognition, interest bearing liabilities are measured at amortised cost using the effective interest method. Gains and losses are recognised in the Consolidated Income Statement when the liabilities are derecognised. Interest bearing liabilities are classified as current liabilities, except when the Group has an unconditional right to defer settlement for at least 12 months after the reporting date, in which case the liabilities are classified as non-current. 140 FINANCIAL REPORT 17.

Financial assets and financial liabilities continued (a) Accounting classification and fair value (i) Financial assets Financial assets are held at FVTPL, amortised cost or designated as FVOCI based on the business model for managing the financial assets and the contractual terms of the cashflows. Classification Held at FVTPL Amortised cost Designated as FVOCI Initial recognition and subsequent measurement Financial assets held at FVTPL, including derivative financial assets, are initially recognised at fair value, with transaction costs recognised immediately in the Consolidated Income Statement. Financial assets held at FVTPL are subsequently remeasured through the Consolidated Income Statement, including any interest income, dividend income and foreign exchange gains and losses, unless hedge accounting is applied. At initial recognition, trade receivables that do not have a significant financing component are recognised at their transaction price. Other financial assets held at amortised cost are initially recognised at fair value plus related transaction costs. Financial assets subsequently measured at amortised cost are measured using the effective interest method and reduced by any impairment losses. Interest income, foreign exchange gains and losses, impairments and any gain or loss on derecognition, are recognised in the Consolidated Income Statement. For certain investments in equity instruments, the Group has made an irrevocable election to present fair value changes in other comprehensive income. Investments in equity instruments designated as FVOCI are subsequently remeasured through other comprehensive income and are not reclassified to the Consolidated Income Statement. Dividends are recognised as other income in the Consolidated Income Statement unless the dividend clearly represents a recovery of part of the cost of the investment. (ii) Financial liabilities Financial liabilities are held at FVTPL or amortised cost. Classification Held at FVTPL Amortised cost Initial recognition and subsequent measurement Financial liabilities held at FVTPL, including derivative financial liabilities, are initially recognised at fair value, with transaction costs recognised immediately in the Consolidated Income Statement. Financial liabilities held at FVTPL are subsequently remeasured through the Consolidated Income Statement, including any interest expense and foreign exchange gains and losses, unless hedge accounting is applied. Financial liabilities held at amortised cost are recognised initially at fair value, net of transaction costs incurred. Financial liabilities held at amortised cost are subsequently measured using the effective interest method. Interest expense and foreign exchange gains and losses are recognised in the Consolidated Income Statement. Any gain or loss on derecognition is also recognised in the Consolidated Income Statement. (iii) Embedded derivatives A derivative embedded within a hybrid contract, with a financial liability or non-financial host, is separated from the host and accounted for as a separate derivative if: – the economic characteristics and risks are not closely related to the host; – a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and – the hybrid contract is not measured at FVTPL. Embedded derivatives are measured at fair value with changes in fair value recognised in the Consolidated Income Statement. A derivative embedded within a hybrid contract containing a financial asset host is not accounted for separately. The financial asset host together with the embedded derivative is required to be classified in its entirety as a financial asset held at FVTPL. 143 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – CAPITAL STRUCTURE AND FINANCING CONTINUED 19. Financial assets and financial liabilities continued (a) Accounting classification and fair value continued (iv) Measurement of fair value The carrying values of the Group’s financial assets and liabilities measured at amortised cost are equal to or approximate their respective fair values, except for senior unsecured notes, which have a fair value of US$617 million (FY22: US$650 million), and lease liabilities, for which a fair value has not been determined. The fair value of the Group’s senior unsecured notes is estimated based on quoted market prices at the reporting date and are classified as Level 1 on the fair value hierarchy as shown below. For financial assets and liabilities measured at fair value, the Group uses quoted marked prices in active markets for identical assets where available. Where no price information is available from a quoted market source, alternative market mechanisms or recent comparable transactions, the fair value is estimated based on the Group’s views on relevant future prices, net of valuation allowances to accommodate liquidity, modelling, credit and other risks implicit in such estimates. The following table shows the Group’s financial assets and liabilities carried at fair value with reference to the nature of valuation inputs used: Level 1 Valuation is based on unadjusted quoted prices in active markets for identical financial assets and liabilities. Level 2 Valuation is based on inputs (other than quoted prices included in Level 1) that are observable for the financial asset or liability, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices). Level 3 Valuation includes inputs that are not based on observable market data.

(3) Recognised in the financial assets reserve in the Consolidated Statement of Comprehensive Income. 144 FINANCIAL REPORT 19. Financial assets and financial liabilities continued (b) Financial risk management objectives and policies The Group is exposed to market, liquidity and credit risk. These risks are managed in accordance with the Group’s portfolio risk management strategy which supports the delivery of the Group’s financial targets while protecting its future financial security and flexibility by taking advantage of the natural diversification of the Group’s operations and activities. A Cash Flow at Risk (CFaR) framework is used to capture the benefits of diversification and to measure the aggregate impact of financial risks on those financial targets. CFaR is measured on a portfolio basis and is defined as the expected reduction from projected business plan cash flows over a one-year horizon in a pessimistic case. In addition to the CFaR framework, deterministic analysis of a range of operational, commodity price and foreign exchange rate scenarios is also used to measure the potential impact on financial targets. (i) Market risk Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risk comprises interest rate risk, foreign currency risk and other price risk, such as equity price risk and commodity price risk. The Group’s activities expose it to market risks associated with movements in interest rates, foreign currencies and commodity prices. The Group predominantly manages currency impacts, input costs and commodity prices on a floating or index basis. This strategy gives rise to a risk of variability in earnings which is measured under the CFaR framework. In executing the Group’s strategy, financial instruments may be employed for risk mitigation purposes within a strict Board of Directors approved mandate, or to align the total Group exposure to the relevant index target in the case of commodity sales, operating costs or debt issuances. Interest rate risk The Group had the following exposure to interest rate risk: US$M Financial assets Cash and cash equivalents Trade and other receivables Other financial assets Financial liabilities Interest bearing liabilities Net exposure FY23 FY22 1,218 153 - (286) 1,085 2,306 102 39 (334) 2,113 The following table demonstrates the sensitivity to a reasonably possible change in interest rates on that portion of financial assets and liabilities affected. With all other variables held constant, the Group’s profit/(loss) after tax would increase/(decrease) as follows: US$M Increase of 100 basis points Decrease of 100 basis points Impact on profit/(loss) after tax FY23 8 (8) FY22 16 (13) The sensitivity analysis assumes that the change in interest rates is effective from the beginning of the year and the fixed/floating mix and balances are constant over the year. However, interest rates and the profile of the Group’s financial assets and liabilities may not remain constant over the coming year and therefore such sensitivity analysis should be used with care. 145 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – CAPITAL STRUCTURE AND FINANCING CONTINUED 19. Financial assets and financial liabilities continued (b) Financial risk management objectives and policies continued (i) Market risk continued Foreign currency risk The Group’s potential currency exposures comprise: – Translational exposure in respect of non-functional currency monetary items; and – Transactional exposure in respect of non-functional currency expenditure and revenues. The functional currency of the Group’s operations is primarily the US dollar. Certain operating and capital expenditure is incurred by operations in currencies other than their functional currency. To a lesser extent, certain sales revenue is earned in currencies other than the functional currency of the operation, and certain exchange control restrictions may require funds to be maintained in currencies other than the operations functional currency. When required, the Group may enter into forward exchange contracts. The following table shows the principal foreign currency risk arising from financial assets and liabilities by currency of denomination: US$M Australian dollar Brazilian real Colombian peso South African rand FY23 (946) (103) (70) 74 FY22 (860) (63) (47) 98 Based on the Group’s net financial assets and liabilities as at 30 June, a weakening of the US dollar against these currencies as illustrated in the table below, with all other variables held constant, would increase/(decrease) the Group’s profit/(loss) after tax, as follows: US$M 10% movement in Australian dollar 10% movement in Brazilian real 10% movement in Colombian peso 10% movement in South African rand Impact on profit/(loss) after tax FY23 FY22 (67) (10) (7) 7 (60) (6) (5) 10 The Group’s other comprehensive income is not exposed to any significant fluctuations as a result of foreign exchange risk arising from financial assets and liabilities. Commodity price risk Contracts for the sale and physical delivery of commodities are executed whenever possible on a pricing basis intended to achieve a relevant index target. Where pricing terms deviate from the index, the Group may choose to use derivative commodity contracts to realise the index price. Contracts for the physical delivery of commodities are not typically financial instruments and are not recognised in the Consolidated Balance Sheet. 146 FINANCIAL REPORT 19. Financial assets and financial liabilities continued (b) Financial risk management objectives and policies continued (i) Market risk continued Provisionally priced commodity sales and purchases contracts Provisionally priced sales or purchases contracts are those for which price finalisation, referenced to the relevant index, is outstanding at the reporting date. Provisional pricing mechanisms embedded within these sales and purchases arrangements have the character of a commodity derivative and are carried at FVTPL as part of trade receivables or trade creditors. Fair value movements on provisionally priced sale contracts are disclosed as other revenue in the Group’s segment results, refer to note 4(b) Segment results. The Group’s exposure at 30 June 2023 to the impact of movements in commodity prices on provisionally invoiced sale and purchase volumes was predominantly around nickel, silver, lead, zinc, metallurgical coal and aluminium. The Group had 3.7kt of nickel, 2.6Moz of silver, 24.4kt of lead, 5.4kt of zinc, 30.0kt of metallurgical coal, 10.0kt of aluminium and 31.5kt of alumina exposure at 30 June 2023 (FY22: 2.3kt of nickel, 1.8Moz of silver, 30.0kt of lead, 5.7kt of zinc, 27.1kt of aluminium) that was provisionally priced. The final price of these sales or purchases will be determined during the first half of FY24. A 10 per cent change in the realised price of these commodities, with all other factors held constant, would increase or decrease profit/(loss) after tax by US$19 million (FY22: US$18 million). The relationship between commodity prices and foreign currencies is complex and foreign exchange rates and commodity prices may move concurrently in response to market conditions. These sensitivities should therefore be used with care. (ii) Liquidity risk The Group’s liquidity risk arises from the possibility that it may not be able to settle or meet its obligations as they fall due. Operational, capital and regulatory requirements are considered in the management of liquidity risk, in conjunction with short and long-term forecast information. In line with the Group’s policy on counterparty credit exposure, the Group only uses counterparties of a high credit standing for the investment of any excess cash. The entities in the Group are funded by a combination of cash generated by the Group’s operations, working capital facilities and intercompany loans provided by the Group. Intercompany loans may be funded by a combination of cash, short and long-term debt. Details of the Group’s major standby arrangement are as follows: FY23 US$M Revolving credit facility(1) Available 1,400 Used - Unused 1,400 (1) The Group has an undrawn revolving credit facility which was extended in December 2022 by one year to December 2027, with the size of the facility in the final year reduced to US$1,200 million. Maturity profile of financial liabilities The maturity profiles of financial liabilities, based on the contractual amounts, are as follows: FY23 US$M Trade and other payables(1) Senior unsecured notes Lease liabilities Other interest bearing liabilities Other financial liabilities – contingent consideration payable Total Carrying amount 986 690 674 377 37 2,764 On demand or less than 1 year 1 to 5 years More than 5 years 968 30 102 315 - 1,415 - 122 331 68 48 569 18 822 715 - - 1,555 Total 986 974 1,148 383 48 3,539 (1) Excludes current input taxes of US$17 million and non-current input and other taxes of US$1 million included in other creditors.

(2) The maturity profile of senior unsecured notes was restated to include future coupon payments, consistent with current year presentation. 147 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – CAPITAL STRUCTURE AND FINANCING CONTINUED 19. Financial assets and financial liabilities continued (b) Financial risk management objectives and policies continued (iii) Credit risk Credit risk management The Group has credit risk management policies in place covering the credit analysis, approvals and monitoring of counterparty exposures. As part of these processes the ongoing creditworthiness of counterparties is regularly assessed. Credit limits are established for customers and reviewed annually or with the release of new information materially impacting the customer’s creditworthiness. Mitigation methods are defined and implemented for higher-risk counterparties to protect revenues, with more than half of the Group’s sales of physical commodities occurring via secured payment terms including prepayments, letters of credit, guarantees and other risk mitigation instruments. Mitigation methods include credit exposure management and overdue accounts monitoring. In addition, leading key risk indicators are actively monitored for all customers to identify any emerging risks. There are no material concentrations of credit risk, either with individual counterparties or groups of counterparties, by industry or geography. The carrying amounts of financial assets represent the maximum credit exposure. Expected credit losses Impairment allowances are based on a forward-looking expected credit loss model. For trade receivables, the Group uses the simplified approach to recognise impairments based on the lifetime expected credit loss. For other receivables, the Group applies the general approach and recognises impairments based on a 12-month expected credit loss. Where there has been a significant increase in credit risk, a loss allowance for lifetime expected credit losses is recognised. Exposures are grouped by external credit rating and security options and an expected credit loss rate is calculated accordingly. Where applicable, actual credit loss experience is also taken into account. For remaining receivables without an external credit rating or security option, a rating of BB (S&P Global Ratings) is used, on the basis that there is no support that it is investment grade, nor is there any evidence of default. Shareholder loan receivable from Sierra Gorda Purchased credit-impaired financial assets are initially recognised at fair value. They are subsequently measured at amortised cost using the credit-adjusted effective interest method, less an allowance for changes in lifetime expected credit losses since initial recognition. The credit-adjusted effective interest rate is determined at initial recognition and not amended for subsequent changes to lifetime expected credit losses since acquisition. Changes in lifetime expected credit losses are recognised as impairment and reversals of impairment of financials assets. The Group’s investment in the Sierra Gorda operation is represented by the carrying value of an equity accounted investment of US$101 million (FY22: US$30 million), and the carrying value of a purchased credit-impaired receivable of US$1,711 million (FY22: US$1,648 million) classified as a loan to an equity accounted investment within trade and other receivables on the Consolidated Balance Sheet. The loan has a contractual interest rate of 8 per cent and the repayment of the loan by the Sierra Gorda operation is dependent on its financial performance. At 30 June 2023, the Group updated its estimated timing of the loan repayments and as a result recognised an impairment of US$71 million (FY22: impairment of US$26 million) which is included in expenses excluding finance costs in the Consolidated Income Statement. The net present value of the expected future cash flows of the loan was determined as US$1,711 million (FY22: US$1,648 million) using a measurement methodology consistent with a Level 3 fair value based on the inputs in the valuation technique. The following table shows the movement in the carrying amount of this receivable: US$M At the beginning of the financial year Acquisition Interest accrued Net impairment Repayments At the end of the financial year FY23 1,648 - 148 (71) (14) 1,711 FY22 - 1,687 55 (26) (68) 1,648 The future loan repayments were informed by a production profile and costs based on management’s planning processes. Refer to the Mineral Resources and Ore Reserves section of note 2(c) for further information on the estimates which underpin the production profile. An effective interest rate of nine per cent, as determined on the date of acquisition, was applied to discount the future loan repayments. Determining the net present value requires management to make certain key estimates, assumptions and judgements, which are consistent with those outlined in note 13 Impairment of non-financial assets. 148 FINANCIAL REPORT 19. Financial assets and financial liabilities continued (b) Financial risk management objectives and policies continued (iii) Credit risk continued Shareholder loan receivable from Sierra Gorda continued The net present value of the expected future cash flows of the loan is most sensitive to the Group’s copper price assumption, with a range of US$3.81/lb to US$4.11/lb used, in real terms. The potential effect of using a reasonably possible alternative copper price assumption on the carrying value of the loan, based on changing this assumption by 10 per cent while holding all other variables constant, is shown in the following table: FY23 US$M Trade and other receivables Loans to equity accounted investments Face value Carrying value Favourable Unfavourable Impact on profit/(loss) after tax 2,185 1,711 90 (164) (c) Capital management The Group allocates capital in line with its strategy and capital management framework. The Group’s priorities for cash flow are to: – Maintain safe and reliable operations and an investment grade credit rating through the cycle; – Distribute a minimum of 40 per cent of Underlying earnings as dividends to shareholders following each six-month reporting period; and – Maximise total shareholder returns through other alternatives including special dividends, share buy-backs and high return investment opportunities which compete for capital. 20.

Weighted average maturity profile of schemes The weighted average duration of the defined benefit obligations is eight years (FY22: seven years) and nine years (FY22: 10 years) for the defined benefit pension schemes and post-retirement medical scheme respectively. Risks associated with defined benefit pension and post-retirement medical schemes The Group’s defined benefit pension and post-retirement medical schemes expose the Group to the risks pertaining to asset value volatility, uncertainty in future benefit payments and uncertainty in future contribution requirements. 150 FINANCIAL REPORT 23.

(2) Awards subject to performance and service conditions. (3) Awards subject to service conditions only. All awards take the form of rights to receive one share in South32 Limited for each right granted, subject to performance and/or service conditions being met. Performance conditions include total shareholder return relative to peer groups and, for FY22 and FY23 Long- Term Incentive Plan and Management Share Plan awards, climate change and portfolio management performance hurdles. Further information on the vesting conditions of performance rights granted in FY23 is disclosed in the Remuneration report. A portion of the 2020, 2021 and 2022 AllShare Plan awards (participants located in Colombia and Mozambique) take the form of rights to receive a cash payment equivalent to the value of South32 Limited shares at the time of payment. Employees in Africa are granted rights on the JSE and all other employees are granted rights on the ASX. Awards do not confer any dividend or voting rights until they convert into shares at vesting. In addition, the awards do not confer any rights to participate in a share issue, however, there is discretion under the plans to adjust the awards in response to a variation in South32 Limited’s share capital. The AllShare JSE plan is eligible to receive a payment equal to the dividend amount that would have been earned on the underlying shares awarded to those participants (Dividend Equivalent Payment). The Dividend Equivalent Payment is made to participants once the underlying shares are issued or transferred to them. No Dividend Equivalent Payment is made in respect of awards that have lapsed or have been forfeited. No other awards are eligible for a Dividend Equivalent Payment. 151 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OTHER NOTES CONTINUED 23. Employee share ownership plans continued (a) Description of share-based payment arrangements (i) Recurring share-based payment plans The awards listed below are subject to the general conditions noted above and may be granted annually subject to approval by shareholders at the annual general meeting for awards to the Chief Executive Officer and by the Board of Directors for all other awards. FY20, FY21, FY22 and FY23 Long-Term Incentive Plan The Long-Term Incentive Plan is the Group’s long-term incentive plan for Lead Team members. Awards have a four-year performance period from 1 July 2019 to 30 June 2023, 1 July 2020 to 30 June 2024, 1 July 2021 to 30 June 2025 and 1 July 2022 to 30 June 2026 respectively. The FY21 Long-Term Incentive Plan award granted to the Chief Executive Officer is subject to a specific vesting cap imposed by the Board of Directors. For other Lead Team members, the Board of Directors retains the discretion to apply a vesting cap to limit the value of the rights which may vest in the ordinary course. FY21 and FY22 Deferred Short-Term Incentive Plan The Deferred Short-Term Incentive Plan is the Group’s short-term incentive plan for Lead Team members. Awards vest in August 2023 and August 2024 respectively, provided participants remain employed by the Group. FY20, FY21, FY22 and FY23 Management Share Plan The Management Share Plan is the Group’s long-term incentive plan for eligible employees below the Lead Team. The Management Share Plan comprises two elements: – Retention rights vesting in August 2023, August 2024 and August 2025 provided participants remain employed by the Group; and – Performance rights vesting in August 2023, August 2024, August 2025 and August 2026 subject to performance conditions and provided participants remain employed by the Group. For the FY21 Management Share Plan awards, the Board of Directors retains the discretion to apply a vesting cap to limit the value of the rights which may vest in the ordinary course. 2020, 2021 and 2022 AllShare Plan The AllShare Plan is the Group’s employee share plan for employees not eligible to participate in the other employee share plans. Awards to the value of at least US$1,250 per employee are granted annually. Awards will vest provided participants remain employed by the Group. The vesting period depends on the participants’ location at the grant date: – Participants in Africa: August 2023, August 2024 and August 2025; and – Participants elsewhere: August 2023 and August 2024. (ii) Transitional share-based payment plans The awards listed below are subject to the general conditions noted above and are either one-off or will not be granted on an ongoing basis. FY21 and FY22 Executive Transitional Award Plan The Executive Transitional Award Plan is a one-off grant made to Lead Team members in recognition of their adjustment from the Management Share Plan (three year retention rights and four year performance rights) to the four year plan at the Group. Awards have a three year performance period from 1 July 2020 to 30 June 2023 and 1 July 2021 to 30 June 2024 respectively. FY20 Management Transitional Award Plan The Management Transitional Award Plan is a grant made to certain eligible employees to bridge the gap between their total target reward at BHP and their total target reward at the Group. The Management Transitional Award Plan has the same conditions as the Management Share Plan and comprises both service and performance conditions. 152 FINANCIAL REPORT 23. Employee share ownership plans continued (b) Employee Share Ownership Plan Trusts The South32 Limited Employee Incentive Plans Trust (the Australian Trust) and the South32 South African AllShare Trust (the South African Trust) are discretionary trusts for the benefit of employees of South32 Limited and its subsidiaries. The trustee for the Australian Trust (CPU Share Plans Pty Ltd) is an independent company, resident in Australia. The trustees for the South African Trust are made up of employer and employee representatives per the Broad-Based Black Economic Empowerment (B-BBEE) requirements under South African law. The Trusts use funds provided by South32 Limited and/or its subsidiaries to acquire shares to enable awards to be made or satisfied under the Group employee share ownership plans. The shares may be acquired by purchase in the market or by subscription at not less than nominal value.  (c) Measurement of fair values The fair value at grant date of equity-settled share awards is charged to the Consolidated Income Statement, net of tax, over the period for which the benefits of employee services are expected to be derived. The corresponding accrued employee entitlement is recorded in the employee share awards reserve. Where awards are forfeited because non-market based vesting conditions are not satisfied, the expense previously recognised is proportionally reversed. If awards do not vest due to a market performance condition not being met, the expense is recognised in full, and the share awards reserve is released to retained earnings. Where shares in South32 Limited are acquired by on-market purchases prior to settling the vested entitlement, the cost of the acquired shares is carried as treasury shares and deducted from equity. Where awards are satisfied by delivery of acquired shares, any difference between their acquisition cost and the cumulative remuneration expense recognised is charged directly to retained earnings, net of tax. The fair value of market-based performance rights is measured using a Monte Carlo methodology. This model considers the following: – Expected life of the award; – Current market price of the underlying shares; – Expected volatility (of the individual company and of each peer group); – Expected dividends; – Risk-free interest rate; and – Market based performance hurdles. The fair value of retention and other non-market-based performance rights is measured using a Black Scholes methodology. This model considers the following: – Expected life of the award; – Current market price of the underlying shares; – Expected volatility; – Expected dividends; and – Risk-free interest rate. 153 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OTHER NOTES CONTINUED 23.

Expected volatility is based on the historical South32 Limited share price volatility at the grant date. The risk-free interest rate and expected volatility does not materially impact service-based awards. 154 FINANCIAL REPORT 23.

There are a number of legal claims or potential claims against the Group, the outcome of which cannot be foreseen at present, and for which no amounts have been disclosed. Actual or potential litigation assets primarily relate to potential recovery of pre-closing tax liabilities in respect of the Sierra Gorda acquisition, with allocation of liability for these pre-closing tax liabilities being disputed with the vendors. The Group has entered into various counter-indemnities of bank and performance guarantees related to its own future performance which are in the normal course of business. Additionally, the Group has provided indemnities against certain liabilities as part of agreements for the disposal of business operations. Having taken appropriate legal advice, the Group believes that a material liability arising from the indemnities provided is remote. 155 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OTHER NOTES CONTINUED 25.

Equity accounted investments continued The Group’s share of contingent liabilities and capital expenditure commitments of significant equity accounted investments as at 30 June 2023 was US$3 million (FY22: US$6 million) and US$58 million (FY22: US$27 million) respectively. The Group uses the term ‘equity accounted investments’ to refer to associates and joint ventures collectively. Associates are entities in which the Group holds significant influence. If the Group holds 20 per cent or more of the voting power of an entity, it is presumed that the Group has significant influence, unless it can be clearly demonstrated that this is not the case. Significant influence can also arise when the Group has less than 20 per cent of the voting power but it can be demonstrated that the Group has the power to participate in the financial and operating policy decisions of the associate. Investments in associates are accounted for using the equity method. Joint ventures are joint arrangements in which the parties with joint control of the arrangement have rights to the net assets of the arrangement. A separate vehicle, not the parties, will have the rights to the assets and obligations for the liabilities, relating to the arrangement. If more than an insignificant share of output from a joint venture is sold to third parties, this indicates that the joint venture is not dependent on the parties to the arrangement for funding and that the parties to the arrangement have no obligation for the liabilities of the arrangement. Joint ventures are accounted for using the equity method. Equity accounted investments are initially recorded at cost, including the value of any goodwill on acquisition. In subsequent periods, the carrying amount of the investment is adjusted to reflect the share of post-acquisition profit or loss and other comprehensive income. After application of the equity method, including recognising the Group’s share of the investees’ results, the value of the investment will be assessed for impairment if there is objective evidence that an impairment of the investment may have occurred. 27. Interests in joint operations Significant joint operations of the Group, which are those with the most significant contributions to the Group’s net profit/(loss) after tax or net assets, are as follows: Significant joint operations Country of operation Principal activity Effective interest % Acquisition date FY23 FY22 Ambler Metals Brazil Alumina Brazil Aluminium Eagle Downs Metallurgical Coal Mozal Aluminium(1) Worsley Alumina(1) United States Brazil Brazil Australia Mozambique Australia Base metals exploration and development options Integrated bauxite mine and alumina refinery Aluminium smelter Metallurgical coal exploration and development option Aluminium smelter Integrated bauxite mine and alumina refinery 11 February 2020 3 July 2014 3 July 2014 14 September 2018 27 March 2015(2) 8 May 2015 50 36 40 50 63.7 86 50 36 40 50 63.7 86 (1) While the Group holds a greater than 50 per cent interest in Worsley Alumina and Mozal Aluminium, participants jointly approve certain matters and are entitled to receive their share of output from the arrangement. (2) The Group initially acquired a 47.1 per cent interest on 27 March 2015 and subsequently acquired a further 16.6 per cent interest on 31 May 2022. Joint operations are joint arrangements in which the parties with joint control have rights to the assets and obligations for the liabilities relating to the arrangement. The activities of a joint operation are primarily designed for the provision of output to the parties to the arrangement, indicating that: – The parties have the rights to substantially all the output and economic benefits of the assets of the arrangement; and – All liabilities are satisfied by the joint participants through their purchases of that output. This indicates that, in substance, the joint participants have an obligation for the liabilities of the arrangement. The consolidated financial statements of the Group include its share of the assets and liabilities, revenues and expenses arising jointly or otherwise from those operations and its revenue derived from the sale of its share of the output from the joint operation. All such amounts are measured in accordance with the terms of each arrangement, which are usually in proportion to the Group’s interest in the joint operation. The assets in these joint operations are restricted to the extent that they are only available to be used by the joint operation itself and not by other operations of the Group. For certain joint operations, the Group has also either pledged, mortgaged or provided a cross charge to joint operation partners over assets within the joint operation. 159 SOUTH32 ANNUAL REPORT 2023 NOTES TO FINANCIAL STATEMENTS – OTHER NOTES CONTINUED 28.

The Financial Report comprises: • Consolidated balance sheet as at 30 June 2023; In our opinion, the accompanying Financial Report of the Company is in accordance with the Corporations Act 2001, including: • Giving a true and fair view of the Group’s financial position as at 30 June 2023 and of its financial performance for the year ended on that date; and • Complying with Australian Accounting Standards and the Corporations Regulations 2001. • Consolidated income statement, Consolidated statement of comprehensive income, Consolidated statement of changes in equity and Consolidated cash flow statement for the year then ended; • Notes including a summary of significant accounting policies; and • Directors’ Declaration. The Group consists of the Company and the entities it controlled at the year-end or from time to time during the financial year. Basis for opinion We conducted our audit in accordance with Australian Auditing Standards. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the Financial Report section of our report. We are independent of the Group in accordance with the Corporations Act 2001 and the ethical requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audit of the Financial Report in Australia. We have fulfilled our other ethical responsibilities in accordance with these requirements. Key Audit Matters The Key Audit Matters we identified are: • Asset valuation; and • Closure and rehabilitation provision. Key Audit Matters are those matters that, in our professional judgement, were of most significance in our audit of the Financial Report of the current period. These matters were addressed in the context of our audit of the Financial Report as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

This is due to the size of property, plant and equipment, intangible assets and equity accounted investments, and the sensitivity of valuations to certain assumptions. The Group had previously impaired the carrying value of several CGUs to equate to their recoverable amount, as required by accounting standards. Combined with the volatility in both commodity and foreign exchange markets, this increases the sensitivity of the current carrying values of these CGUs to potential impairment or reversal. The Group has recorded an impairment charge of US$1,300m in the Hermosa – Taylor deposit AOI resulting from identification of an impairment indicator. This further increased our audit effort in this key audit area. The Group uses sophisticated models to perform their assessment of impairment or reversal indicators and fair value less cost of disposal for impairment testing, where required. The Group’s models use life of operation and project plans, approved budgets, and a range of external sources as inputs to the assumptions. Modelling using forward-looking assumptions tends to be prone to greater risk for potential bias, error and inconsistent application. These conditions necessitate additional scrutiny by us to address the objectivity of inputs and their consistent application. We focused on the significant forward-looking assumptions the Group applied in their models, including: • Forecast commodity prices and foreign exchange rates – the current economic climate has resulted in significant volatility in forecast commodity prices across the Group. The Group’s models are sensitive to small changes in these price assumptions, as well as changes to foreign exchange rates, particularly the South African Rand, which increases forecasting risk. • Forecast operating cash flows, production volumes, capital expenditure and reserve and resource estimates – these are determined by the Group based on historical performance adjusted for expected changes or plans for development, including consideration of regulatory approvals. This drives additional audit effort specific to the feasibility of the forecasts and consistency with the Group’s strategy. • Discount rates - these are complicated in nature and vary according to the conditions and environment the CGUs are subject to from time to time. • Carbon price – the Group incorporates carbon price assumptions in its modelling based on enacted local schemes and assumptions of longer-term pricing and timing in the jurisdictions they operate and transact in. We involved valuation specialists to supplement our senior audit team members in assessing this key audit matter. Our procedures included: • We considered the appropriateness of the fair value less cost of disposal method applied by the Group to perform the annual test for impairment against the requirements of the accounting standards. • We assessed the integrity and consistency of the models used for impairment testing and assessment of impairment or reversal indicators on a sample basis, including the accuracy of the underlying formulas and consistency of modelling to the prior year. • We assessed the Group’s view of the indicators leading to impairment testing for the Hermosa – Taylor deposit AOI. We recalculated the impairment charge and compared to the amounts recognised. • We compared the forecast operating cash flows, production volumes, capital expenditure and reserve and resource estimates contained in the models to the life of operation plans incorporated in the approved budgets and study estimates incorporated in project plans. We assessed the accuracy of the Group’s previous forecasts to assist with this assessment. • We considered the sensitivity of the models by varying key assumptions, such as forecast commodity prices, foreign exchange rates, carbon pricing, discount rates, pre-production capital expenditure and risking applied to future development projects for probability, within a reasonably possible range. We did this to identify those CGUs at higher risk of impairment or reversal and to focus our further procedures. • We assessed the scope, objectivity and competence of the Group’s internal experts responsible for preparation of key resource and reserve estimates and compared these estimates to those incorporated in the life of operation and project plans where applicable. • We checked the preparation of key resource and reserve estimates against key requirements of the JORC code, including testing controls over the appointment of Competent Person and checking declarations made. • We challenged the Group’s significant forecast operating cash flow, capital expenditure and production volume assumptions. We compared key events to the Board approved plan and strategy. We applied increased scepticism to forecasts in the areas where previous forecasts were not achieved. We compared key forecast expenditure to published studies of industry trends and expectations, and considered differences for the Group’s operations. We used our knowledge of the Group, their past performance, business and customers, and our industry experience. • Working with our valuation specialists, and considering the risk factors specific to the Group, we compared the discount rates to publicly available market data for comparable entities. We also compared forecast foreign exchange rates to published views of market commentators. • We compared forecast commodity prices to published views of market commentators on future trends and long-term supply agreements. • We involved our sustainability specialists and inquired of key members of the Group’s climate team on their progress of climate-related strategy. We compared those areas identified by the Group having an impact on asset valuation to our knowledge of their industry and business. We tested key climate-related assumptions incorporated into the financial modelling of carbon pricing assumptions against locally enacted country specific schemes and longer term published industry views. • We assessed the disclosures in the Financial Report using our understanding obtained from our testing and against the requirements of the accounting standards. 165 SOUTH32 ANNUAL REPORT 2023 INDEPENDENT AUDITOR’S REPORT Closure and rehabilitation provision (US$1,938m) Refer to Note 15 Provisions to the Financial Report. The key audit matter How the matter was addressed in our audit Closure and rehabilitation provisioning was a key audit matter due to the size of the provision and the judgement we used to audit the provision estimates across multiple sites the Group operates. Closure and rehabilitation activities are governed by Group policies based on legal and regulatory requirements, which differ across multiple jurisdictions. We focused on the following assumptions the Group applied in determining the provisions using their closure and rehabilitation plans: • Nature and extent of activities required at sites, including the magnitude of possible contamination and disturbance, which are inherently challenging to assess. • Timing of when closure and rehabilitation will take place, which increases estimation uncertainty given the unique nature of each site and long timeframes involved. • Forecast cost estimates incorporating historical experience, which may not be a reliable predictor of such costs particularly in an inflationary economy, and risk adjustments. The Group engages external experts periodically to assist in their determination of these estimates. • Economic assumptions, including country specific discount rates, which are complicated in nature. Our procedures included: • Comparing the basis for recognition and measurement of the closure and rehabilitation provision for consistency with environmental and regulatory requirements and criteria in the accounting standards. • Evaluating the methodology applied by the Company’s expert in determining the nature and extent of closure and rehabilitation activities by comparison to industry practice. • Evaluating key assumptions used in the closure and rehabilitation provision, relevant to the jurisdictions of the sites the Group operates, by: • Comparing the nature and extent of activities costed to a sample of the Group’s closure and rehabilitation plans and relevant regulatory requirements. • Comparing the timing of closure and rehabilitation activities to the Group’s resources and reserve estimates and the expected production profile contained in the life of operation plans. • Assessing the scope, objectivity and competence of the Group’s internal and external experts to provide closure and rehabilitation cost estimates. • Comparing a sample of cost estimates of the activities, incorporating allowance for uncertainties, to historical experience and underlying documentation, the Group’s external expert estimates, and our knowledge of the Group, forecast economic conditions and its industry. Involving our sustainability closure specialists, we tested key climate and environment-related assumptions incorporated into the financial modelling of closure cost activities against environmental laws and regulations and industry guidelines. • • Working with our valuation specialists, comparing country specific discount rate assumptions to market observable data, including risk free rates. • Assessing the disclosures in the Financial Report using our understanding obtained from our testing against the requirements of the accounting standard. 166 FINANCIAL REPORT INDEPENDENT AUDITOR’S REPORT Other Information Other Information is financial and non-financial information in South32 Limited’s annual reporting which is provided in addition to the Financial Report and the Auditor's Report. The Directors are responsible for the Other Information. Our opinion on the Financial Report does not cover the Other Information and, accordingly, we do not express an audit opinion or any form of assurance conclusion thereon, with the exception of the Remuneration Report and our related assurance opinion. In connection with our audit of the Financial Report, our responsibility is to read the Other Information. In doing so, we consider whether the Other Information is materially inconsistent with the Financial Report, or our knowledge obtained in the audit, or otherwise appears to be materially misstated. We are required to report if we conclude that there is a material misstatement of this Other Information, and based on the work we have performed on the Other Information that we obtained prior to the date of this Auditor’s Report we have nothing to report. Responsibilities of the Directors for the Financial Report The Directors are responsible for: • Preparing the Financial Report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act • 2001; Implementing necessary internal control to enable the preparation of a Financial Report that gives a true and fair view and is free from material misstatement, whether due to fraud or error; and • Assessing the Group and Company’s ability to continue as a going concern and whether the use of the going concern basis of accounting is appropriate. This includes disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless they either intend to liquidate the Group and Company or to cease operations, or have no realistic alternative but to do so. Auditor’s responsibilities for the audit of the Financial Report Our objective is: • To obtain reasonable assurance about whether the Financial Report as a whole is free from material misstatement, whether due to fraud or error; and • To issue an Auditor’s Report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Australian Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error. They are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the Financial Report.

KPMG Graham Hogg Partner Perth 7 September 2023 167 SOUTH32 ANNUAL REPORT 2023 RESOURCES AND RESERVES Information Competent Persons Accompanying tables 169 170 171 168 RESOURCES AND RESERVES INFORMATION As required by Chapter 5 of the Australian Securities Exchange (ASX) Listing Rules, we report Mineral Resources and Ore Reserves (including Coal Resources and Coal Reserves) in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code). In this report, information relating to Mineral Resources and Ore Reserves is based on, and fairly represents, information and supporting documentation prepared by our Competent Persons. A Competent Person is defined in the JORC Code. They must have a minimum of five years of relevant experience in the style of mineralisation or type of deposit under consideration and the activity being undertaken. Each of our Competent Persons have given consent to the inclusion of the information in this report in the form and context in which it appears. You can find more details on each of their professional affiliations, employer and areas of accountability on page 170. Unless we state otherwise, all Competent Persons listed are full-time employees at South32, or at one of our related entities. We report Mineral Resources and Ore Reserves in 100 per cent terms and represent estimates as at 30 June 2023. Our Mineral Resource estimations include Measured and Indicated Mineral Resources which, after the application of all Modifying Factors, and development of a mine plan, have been classified as Ore Reserves. We report all quantities as dry metric tonnes, unless stated otherwise. It is important to note that Mineral Resources and Ore Reserves are estimations, not precise calculations. We have rounded tonnes and grade information to reflect the relative uncertainty of the estimate, which is why minor computational differences may be present in the totals. Our long-range forecasts are the basis for the commodity prices and exchange rates used to estimate the economic viability of Ore Reserves. Our planning processes consider the impacts of climate change on our Ore Reserves estimates, including assessments of operating costs and the impact of extreme weather events on the expectation of economic extraction. Our Ore Reserves are within existing permitted mining tenements. Our mineral leases are of sufficient duration, or convey a legal right to renew the tenure, to enable all Ore Reserves on the leased properties to be mined in accordance with At a glance - Resources and Reserves (as at 30 June 2023) Operations and development options Worsley Alumina Brazil Alumina (MRN) Sierra Gorda Cannington Taylor Clark Peake Arctic Bornite Cerro Matoso Australia Manganese South Africa Manganese(2) Illawarra Metallurgical Coal(2)(3) Eagle Downs Total Ore/Coal Reserve (Mt) Reserve Life Years(1) Total Mineral/ Coal Resource (Mt) 217 39 15 33 49 99 99 13 4.0 6.0 9.0 4.7 41 23 1,100 448 1,890 73 153 55 3.3 37 148 316 140 201 1,190 1,140 (1) Scheduled extraction period in years for the total Ore Reserves in the approved Life of Operation Plan.

Foreign estimate In the market announcement “South32 to Acquire a 45 per cent Interest in the Sierra Gorda Copper Mine” dated 14 October 2021, we reported on the estimates of mineral resources and mineral reserves for the Sierra Gorda copper mine. These estimates of mineral resources and mineral reserves are foreign estimates under the ASX Listing Rules and are not reported in accordance with the JORC Code. We completed the acquisition on 22 February 2022 and in accordance with ASX Listing Rule 5.14.1, our technical team has been reviewing available information in collaboration with the Sierra Gorda operational team to verify the foreign resource and reserve estimates, with the intention of enabling these estimates to be reported in accordance with the JORC Code. Following review of all information, we have updated the Mineral Resource estimate in accordance with the JORC Code and it is included in page 172. With respect to the mineral reserve estimate, we are not in possession of any new information or data relating to the foreign estimate that materially impacts on the reliability of the estimates or our ability to verify the foreign mineral reserve estimates as Ore Reserves in accordance with the JORC Code. We confirm that the information contained in our 14 October 2021 market announcement in relation to the mineral reserve foreign estimates continues to apply and has not materially changed. The Competent Person has not done sufficient work to classify the foreign estimates as Ore Reserves in accordance with the JORC Code and it is uncertain at this time whether, following evaluation and further exploration, the foreign estimates will be able to be reported as Ore Reserves in accordance with the JORC Code. Our governance arrangements and internal controls We have internal standards and governance arrangements that cover regulatory requirements for public reporting. To ensure correct and accurate public reporting with respect to Mineral Resources and Ore Reserves, our governance processes are managed by the Resource and Reserve Governance function in coordination with the Company Secretariat function. Our comprehensive review and audit program is aimed at assuring our Mineral Resource and Ore Reserve estimates. This includes: – Annual review of Mineral Resources and Ore Reserves declarations and reports; – Annual review of reconciliation performance metrics for operating mines; – Periodic internal mine planning and Ore Reserve audits; and – Independent audits of Exploration Results, Mineral Resources or Ore Reserves that are new or have materially changed. 169 SOUTH32 ANNUAL REPORT 2023 RESOURCES AND RESERVES CONTINUED In FY23, we undertook two independent assurance audit of Exploration Results, Mineral Resource or Ore Reserve estimates and three internal mine planning and Ore Reserve assurance audits. The frequency and scope of the audits are generally a function of the perceived risks and uncertainties associated with a particular Mineral Resource and Ore Reserve. The accompanying tables, on pages 171 to 176, outline our Mineral/Coal Resources and Ore/Coal Reserves holdings. Our exploration, research and development Our operations carry out exploration, research and development necessary to support our activities. Our brownfield exploration activities target the delineation and categorisation of mineral deposits connected or adjacent to our existing operations. Our greenfield exploration activities focus on the discovery and delineation of opportunities outside of our operational footprint, with a bias to base metals. During FY23 we continued to expand our global exploration footprint. We funded greenfield exploration in Australia, Peru, Argentina, Ireland, Canada and the United States of America. Our exploration expenditure for FY23 was US$107 million (FY22: US$74 million) of which US$36 million related to brownfield and US$71 million related to greenfield (FY22: US$18 million and US$56 million respectively).

Mineral Resources are sub- divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories (JORC Code). Mineralisation Any single mineral or combination of minerals occurring in a mass, or deposit, of economic interest (JORC Code). Modifying Factors Considerations used to convert Mineral Resources to Ore Reserves. These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors (JORC Code). Net smelter return An estimate of revenue derived from the sale of products and concentrates following the application of metallurgical recoveries and deducting transport costs, treatment and refining charges, penalties and royalties. For Sierra Gorda, mining cost is also included in the calculation. Ore Reserve The economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Prefeasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified (JORC Code). PEng A licenced member of Professional Engineers of Ontario (PEO). Probable Ore Reserve The economically mineable part of an Indicated and, in some circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Ore Reserve is lower than that applying to a Proved Ore Reserve (JORC Code). Proved Ore Reserve The economically mineable part of a Measured Mineral Resource. A Proved Ore Reserve implies a high degree of confidence in the Modifying Factors (JORC Code). Pr.Sci.Nat.
