This measure enables precise identification of green products and services across the entire value chain and helps investors assess revenue exposure to green activities within the Group. Based on the criteria developed by FTSE Russel, Sibanye-Stillwater utilised revenue from the following operations in determining its FTSE Russell green revenue factor: SA gold (limited to the Cooke operation); SA PGMs (excluding Mimosa); and US PGMs (including recycling). The FTSE Russell green revenue factor is a non-IFRS measure and it should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS Accounting Standards OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 3 2023 REVENUE PER PRODUCT (Rbn) 71.1 30.3 5.2 4.3 2.1 0.7 PGMs Gold Chrome Nickel Zinc Other 2023 PRODUCTION 1.7Moz SA 4E PGMs 811koz gold 427koz US 2E PGM 310koz US 3E PGM recycling 76kt zinc metal produced (payable) 7.1kt nickel 2023 REVENUE PER OPERATION R113.7bn (US$6.2bn) 55.6 29.1 10.5 13.3 3.0 2.3 -0.1 SA PGM operations SA gold operations US PGM underground operations US PGM recycling Sandouville nickel refinery Century zinc retreatment operation Group corporate and reconciling items CLICK TO VIEW 'b G < > - OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION ABOUT SIBANYE-STILLWATER continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 4 A UNIQUE, GREEN PORTFOLIO OF GEOGRAPHICALLY DIVERSIFIED ASSETS AND COMMODITIES AMERICAS ASSETS US PGM OPERATIONS Stillwater mine (100%) Mineral Reserves: 15.7Moz 2E East Boulder mine (100%) Mineral Reserves: 10.6Moz 2E PGM EXPLORATION Marathon (13.9%)* Mineral Resources: 0.8Moz 2E PGM RECYCLING Columbus Met complex (100%) LITHIUM EXPLORATION Rhyolite-Ridge (6.91%)* Mineral Resources: 232kt LCE COPPER EXPLORATION Altar (48.61%)* Mineral Resources: 6,386Mlb Cu SOUTHERN AFRICAN ASSETS SA PGM OPERATIONS Marikana (80.64%) Mineral Reserves: 16.5Moz 4E Rustenburg (74%) Mineral Reserves: 9.3Moz 4E Kroondal (87%) Mineral Reserves: 0.7Moz 4E Mimosa (50%)* Mineral Reserves: 1.6Moz 4E SA PGM EXPLORATION Akanani (80.13%) Mineral Resources: 31.6Moz 4E Limpopo: Voorspoed and Doornvlei (80.64%), and Dwaalkop (40.32%) Mineral Resources: 19.9Moz 4E SA GOLD OPERATIONS Kloof (100%) Mineral Reserves: 1.8Moz Au Beatrix (100%) Mineral Reserves: 0.7Moz Au Driefontein (100%) Mineral Reserves: 2.9Moz Au Cooke surface (76%) Mineral Reserves: 0.1Moz Au DRDGOLD (50.28%)* Mineral Reserves: 2.9Moz Au SA GOLD DEVELOPMENT Burnstone (100%) Mineral Reserves: 2.5Moz Au SA GOLD EXPLORATION SOFS (Southern Free State project) (100%) Mineral Resources: 6.9Moz Au SA URANIUM EXPLORATION Beisa (100%) Mineral Resources: 27.0Mlb U₃O₈ Cooke (76%) Mineral Resources: 32.2Mlb U₃O₈ EUROPEAN ASSETS LITHIUM DEVELOPMENT Keliber lithium project (79.82%) Mineral Reserves: 182kt LCE NICKEL OPERATIONS Sandouville refinery (100%) AUSTRALIAN ASSETS ZINC OPERATIONS Century (100%) Mineral Reserves: 1,726Mlbs Zn COPPER EXPLORATION Mount Lyell (100%) Mineral Resources: 1,609Mlbs Cu CIRCULAR ECONOMY OPERATIONS BATTERY METALS GREEN METALS * Non-managed PGM = platinum group metals, Au = gold, Cu = copper, LCE = lithium carbonate equivalent, Zn = Zinc, U3O8 = uranium Mineral Resources are inclusive of Mineral Reserves 1.

OUR VISION TO BE A LEADER IN SUPERIOR SHARED VALUE FOR ALL STAKEHOLDERS This vision statement speaks to our conviction that responsibly-derived minerals (mining that minimises harm to people and the planet) are the source of significant economic, social and environmental benefit to society, both globally and locally. OUR STRATEGY Our strategy speaks to our ambition to secure for the Group a position in the global resources sector as a progressive, forward-thinking provider of green metals and energy solutions. Our strategy has a three-dimensional approach, in which our priorities are layered in terms of: strategic foundation; strategic essentials; strategic differentiators. We unpack our strategy on page 48 of the 2023 Integrated report. THE CONTEXT FOR OUR STRATEGY ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– In a world with increasing volatility and an accelerating pace of change, we recognise that the future is inherently uncertain with levels of strategic risk elevating. This is the basis of both threats and opportunities for our business. Anticipation through monitoring of early signals combined with agility in positioning of the business using anti-fragility principles enables us to seize advantage through active engagement with critical risks, (see External environment for our business and operations on page 36 of the 2023 Integrated report) • Decarbonisation is a key concern for governments and businesses across the world. In response, the world’s energy mix is moving towards reduced greenhouse gas (GHG) emissions. We expect that current trends toward nuclear power, renewable energy (wind, solar, battery storage), green hydrogen, and the electrification of mobility, will intensify. Our response is to build a Unique portfolio of green metals and energy solutions that reverse climate change, contributing towards the world’s critical needs • Geopolitical developments are changing allegiances and trading patterns across the world, with national elections scheduled to take place in 64 countries in 2024 likely to further impact foreign policies and geopolitics. Security of supply is becoming a stronger priority, for nations and for regional blocs, with the integrity of critical minerals value chains of significant importance. This presents key opportunities for the Group to differentiate its offer, partnering to Build pandemic-resilient ecosystems that are invulnerable to geopolitical developments • Intelligent advances are accelerating, with digital technologies fulfilling an increasing role in every facet of life. Rapid advances in artificial intelligence provide massive transformative opportunities, while also raising a new spectrum of ethical issues. This presents opportunities to “rewire” our business to embrace new capabilities and augment human performance through technology taking key business outcomes to a different level. We are committed to our quest to become Inclusive, diverse and bionic as a strategic differentiator • While divisions are starting to emerge, stakeholder expectations of business are placing continued high levels of scrutiny on ESG and sustainability credentials. We believe that the most successful businesses will be those that earn stakeholder credibility by demonstrating meaningful socioeconomic purpose beyond the delivery of returns to their shareholders. We recognise this as an opportunity to distinguish ourselves in the market by being Recognised as a force for good, and thereby strategically differentiating ourselves by creating superior shared value through our business activities. This underscores our commitment to stakeholder capitalism We use the term “grey elephants” (see page 35 of the Integrated report for more detail) to refer to highly-probable, high-impact, yet often neglected catalysts of change that are shaping the 2020s; events with global repercussions, such as the COVID-19 pandemic, Russia’s invasion of Ukraine, and the conflicts in the Middle East. While the grey elephants signal disruption and threat to conventional business activity, they also present significant opportunities for organisations that embrace the future, and are bold and agile enough to capture the moment. Early awareness of grey elephants and decisive strategic responses are required to sustain business effectiveness.

UNPACKING OUR THREE-DIMENSIONAL STRATEGY OUR STRATEGIC FOUNDATION This defines the impact we aspire to make in the global economy and in local societies influenced by our operations; it is the difference our business makes. It embraces our purpose, vision and values, as well as the core principles that guide our decisions, including our commitment to ESG excellence and shared value. Our Umdoni tree is at the heart of our strategic foundation and represents our fundamental approach to business. The Sibanye-Stillwater Umdoni tree symbolises our approach to stakeholder capitalism. The roots of the tree hold our values, signifying that below the surface of success and competition, Sibanye-Stillwater iCARES. Our roots, our iCARES values, are at the heart of all that we do, the decisions we make and how we conduct our business. These values are enshrined in our Code of ethics and form the basis of the organisational growth and culture rejuvenation programme currently underway. iCARES VALUES INNOVATION We intentionally find new ways to do things better. We will all understand the need to innovate, develop innovators, encourage innovation, invite everyone to innovate; and we recognise innovation. COMMITMENT We are committed to the protection of life, health and the environment; to operational excellence, to high standards of governance, to ethical conduct and regulatory compliance, and to adhering to best practice industry disclosure and reporting standards. ACCOUNTABILITY We are accountable to our stakeholders for delivering on our key operational targets and strategic objectives; for identifying, managing and mitigating the risks inherent in our business; and for maximising the return on capital deployed. RESPECT We treat people fairly, respect each other, value the richness of human diversity and support employees in realising their full potential. ENABLING We enable prosperous and sustainable operations by engaging with our stakeholders, empowering our employees in their professional development, and offering doorstep communities skills and resources to thrive post- mining. SAFETY We acknowledge that working at depth, with heavy machinery, presents risks to life and limb; therefore we prioritise all practical, technical and behavioural measures to reduce safety and health risks to near zero. OUR STRATEGIC ESSENTIALS Support attainment of operational and business excellence We have five strategic imperatives that are instrumental for us to compete on the global stage. OUR STRATEGIC DIFFERENTIATORS Represent the opportunities that we have identified to be distinctive in the global minerals industry Our four strategic differentiators represent our opportunities to be distinctive in the global minerals industry.

The grey elephants cover seven major global trends that we expect to have a pronounced impact on the fabric of global society and the global economy. Acute disruptive events with global implications, which we have characterised as pandemics, are an important additional component of the grey elephant framework. Such events have a dramatic impact on society and the economy, creating conditions conducive to change and stimulating acceleration in the major global trends represented by the other grey elephants. The graphic below identifies how the grey elephants have played out in 2023, with a focus on aspects of relevance to our business activities. These developments validate the grey elephants as a compelling framework through which to anticipate the future world in which we will operate and conduct business, assisting us in remaining relevant to future conditions. Economies are not responding in the expected way to central bank interventions with strong economic activity continuing despite high interest rate environments. This is one of the key factors causing distortions in commodity markets. Departures from traditional demographic age profiles are influencing national competitiveness in many parts of the world with associated changes in social dynamics. 2023 was the warmest year on record with an increasing number of extreme weather events and sustained shifts in local climates. Impetus towards establishment of a global clean energy economy is building. Sentiment is divided on whether commercial incentives are a key element in catalysing social advancement by stimulating economic growth through at risk investment that promotes innovation. The most successful economies are those that recognise the value generated by private capital with an ability to earn strong financial returns coupled with a commitment to sustainability. Confidence in the supply of critical resources is under threat with increasing disruption to global supply chains. As a result, many nations are seeking to reduce dependence on dominant sources and gain control of their own assured supply channels. The voice of society is becoming stronger fuelled, despite censorship, by abundant availability of information much of which is unverified or propagated by influencers through social media. While national elections will take place in a record 64 countries in 2024, alternative platforms for expression are increasingly being utilised. Allegiances are shifting in response to geopolitical developments and as foreign policies evolve across the world with significant implications for critical minerals supply chains. Many African countries are in a unique position as part of a non- aligned region with relatively undeveloped significant mineral resources. Generative artificial intelligence emerged into general application in 2023 with adoption at an unprecedented rate. These developments have profound implication with business needing to establish frameworks for responsible use to leverage benefits of the technology. Adapting culture and strategy to navigate the grey elephants sharply transforming the world 'b G < > - BOARD AND EXECUTIVE LEADERSHIP OUR BOARD AS AT 31 DECEMBER 2023 BOARD CHARACTERISTICS1 Independent Non-Executive Chairman A unitary Board with an appropriate balance of relevant diversity in gender, culture, age, fields of knowledge, skills and experience.

The lower value in use led to an after tax equity accounted impairment of property, plant and equipment amounting to R1,384 million (see note 9.3) and the further impairment of the investment in the equity-accounted investee of R423 million (included in SA PGM in the segment report — see note 2). The weighted average PGM (4E) basket price, nominal discount rate and life-of-mine used in the Mimosa impairment assessment was R26,632/4Eoz, 31.2% and 11 years, respectively. The recoverable amount was determined as R2,757 million OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 28 'b G < > - The impairment of mining assets and goodwill for the year ended 31 December 2023 relates to the following classes of assets: Figures in million – SA rand Stillwater1 Sandouville nickel refinery2 Century retreatment operation3 Burnstone4 Kloof5 Other1 Total Mine development, infrastructure and other 10,222 1,430 2,434 1,115 1,616 27 16,844 Land, mineral rights and rehabilitation 20,326 67 843 — — — 21,236 Exploration and evaluation assets — — 412 — — — 412 Intangible assets — 86 — — — — 86 Goodwill 8,352 23 — — — 60 8,435 Total impairment 38,900 1,606 3,689 1,115 1,616 87 47,013 1 Various operational constraints, as previously reported, in the ramp-up of the Blitz project, coupled with higher than inflation increases in operating costs and a decrease in medium to long-term forecast palladium prices, resulted in a decrease in the expected future net cash flows from the US PGM operation. The higher weighted average cost of capital, driven by a higher beta, in combination with the aforementioned factors, contributed to the reduced value in use at year end, which led to an impairment of property, plant and equipment and goodwill amounting to R38,900 million. In addition, goodwill allocated to the US PGM operation amounting to R60 million pertaining to the acquisition of SFA (Oxford) was impaired 2 An onerous supply contract (see note 13), higher fixed and variable costs, significantly reduced expected sustainable production volumes and higher than initially expected sustaining capital expenditure, resulted in the decrease in expected future net cash flows from the Sandouville nickel refinery. This, together with lower nickel prices, reduced the value in use at year end and led to an impairment of property, plant and equipment, intangible assets and goodwill amounting to R1,606 million. Further studies are currently ongoing to determine the future optimal usage of infrastructure at the Sandouville nickel refinery 3 Lower than expected production volumes, above inflationary increases in operating costs, higher sustaining capital, the approaching end of life-of-mine and the diminishing window of opportunity to develop and operate the expansion projects concurrent with the ongoing operation, resulted in a decrease in the expected future net cash flows from the Century zinc retreatment operation. The lower value in use led to an impairment of property, plant and equipment amounting to R3,689 million 4 Consistent with the requirements of the Group’s capital allocation framework, the Burnstone project (included in the SA Gold corporate and reconciling items reportable segment) will be delayed and is expected to ramp-up again during 2025. The additional costs during the delay, the deferral of mine ramp-up and higher weighted average cost of capital due to an increase in the beta, risk free rate and cost of debt, has resulted in a decrease in the expected future net cash flows from Burnstone. The lower value in use led to an impairment of property, plant and equipment amounting to R1,115 million 5 Operational constraints, including seismicity and cooling, at the Kloof 4 shaft, compounded by the shaft incident during H2 2023 that damaged the shaft infrastructure, resulted in a severe deterioration in productivity that negatively impacted the financial viability of the Kloof 4 shaft. Consequently, during 2023, following a consultative process, the Group announced the closure of Kloof 4 shaft, which led to the specific impairment of property, plant and equipment amounting to R1,616 million The assumptions applied in the value in use impairment calculation as well as the recoverable amount for each of the cash-generating units (CGU) impacted by the impairments are set out below: Stillwater Sandouville nickel refinery Century zinc retreatment operation Burnstone Weighted average PGM (2E) basket price1 US$/2Eoz 1,281 Weighted average nickel price1 US$/lbs 8.9 Weighted average cobalt price1 US$/lbs 15.8 Weighted average zinc price1 A$/t 3,873 Weighted average gold price1 R/kg 1,012,625 Inflation rate2 % 2.5 1.6 2.9 6.0 Nominal discount rate3 % 12.0 7.4 9.3 18.9 Life-of-mine4 (life-of-refinery) years 46 23 4 25 Recoverable amount R' million 22,246 — — 3,799 1 The weighted average commodity prices and exchange rate were derived by considering various bank and commodity broker consensus forecasts 2 The inflation rate is based on the expected forecast inflation rate for the geographic region which most affects the CGU's cash flows 3 The nominal discount rate is calculated as the weighted average cost of capital of the respective CGUs 4 Periods longer than five years are considered appropriate based on the nature of the operations since a formally approved life-of-mine plan is used to determine cash flows over the life of each mine based on the available reserves OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 29 'b G < > - The Group's estimates and assumptions used in the 31 December 2023 impairment testing include: Gold operations1 PGM operations Europe (Sandouville nickel refinery)2 AUS operatio ns 2023 2022 2021 2023 2022 2021 2023 2022 2023 Average gold price3,5 R/kg 1,072,364 869,035 773,398 Average PGM (4E) basket price4,5 R/4Eoz 29,124 27,566 24,422 Average PGM (2E) basket price5 US$/2Eoz 1,281 1,334 1,180 Average nickel price5 US$/lbs 8.9 8.3 Average cobalt price5 US$/lbs 15.8 22.1 Average zinc price5 A$/t 3,873 Nominal discount rate — South Africa6,7 % 13.7 - 15.8 13.9 - 15.8 11.5 - 13.5 22.5 - 22.7 22.5 - 22.6 20.0 Nominal discount rate — US7 % 12.0 12.9 8.3 Nominal discount rate — Europe7 % 7.4 9.8 Nominal discount rate — Australia7 % 9.3 Inflation rate — South Africa3,8 % 6.0 6.5 6.0 6.0 6.5 6.0 Inflation rate — US8 % 2.5 4.0 2.0 Inflation rate — Europe8 % 1.6 2.5 Inflation rate — Australia8 % 2.9 Life-of-mine3,9 years 4 - 11 4 - 10 4 - 9 14 - 47 15 - 49 17 - 50 23 24 4 1 Include the operating gold mines Driefontein, Kloof and Beatrix 2 The Keliber impairment assessment at 31 December 2023 applied an average lithium hydroxide price of US$22,933/t, nominal discount rate of 10.1%, inflation rate of 2% and a life-of-mine of 24 years 3 The estimates and assumptions used in the impairment assessment of the Burnstone project include an average gold price of R1,012,625/kg (2022: R793,473/kg, 2021: R729,270/kg), inflation rate of 6.0% (2022: 6.5%, 2021: 6.0%) and life-of-mine of 25 years (2022: 22 years, 2021: 24 years) 4 The average PGM basket price used on the Mimosa equity-accounted joint venture was R26,632/4Eoz (2022: R25,420/4Eoz, 2021: R21,943/4Eoz) 5 The average prices and the exchange rate were derived by considering various bank and commodity broker consensus forecasts 6 Nominal discount rate for the Burnstone project is 18.9% (2022: 17.4%, 2021: 15.3%) and for the equity-accounted joint venture Mimosa, 31.2% (2022: 30.7%, 2021: 24.4%) 7 The nominal discount rate is calculated as the weighted average cost of capital of the respective CGUs 8 The inflation rate is based on the expected forecast inflation rate in the geographical region which most affects the CGU's cash flows 9 Periods longer than five years are considered appropriate based on the nature of the operations since a formally approved life-of-mine plan is used to determine cash flows over the life of each mine based on the available reserves The cash flows are based on the annual life-of-mine plan that takes into account the following: • Proved and probable ore reserves of the CGUs • Cash flows are based on the life-of-mine plan • Sustaining capital expenditure estimates over the life-of-mine plan Results of impairment assessments for the Group's gold operations, SA PGM operations and goodwill allocated to other CGUs Other than the impairments described above, no further impairment was identified for the Group's gold and SA PGM CGUs with allocated goodwill. However, holding all other assumptions constant, a decrease in the average gold price used for Kloof (R1,064,988/kg) exceeding 6.3% will result in impairment. Management believes that currently, there are no reasonably possible changes in the assumptions used to assess impairment, which would lead to an impairment for any of the Group's CGUs, other than Kloof.

Aldebaran is a mineral exploration company 3 The Group holds 13.90% in Generation Mining Limited which is incorporated in Canada and listed on the TSX. Generation Mining Limited is in the process of developing the Marathon copper-palladium project 4 The Group holds 6.91% in ioneer Limited (ioneer) which is incorporated in Australia. ioneer is an emerging lithium-boron producer listed on the Australian Securities Exchange (ASX) and currently owns 100% of the Rhyolite Ridge lithium-boron project (Rhyolite Ridge) in Nevada in the US. Sibanye-Stillwater reached an agreement with ioneer to establish a 50% joint venture to develop Rhyolite Ridge, which was still subject to the fulfilment of certain conditions precedent at 31 December 2023. As announced by the Group on 13 January 2023, ioneer received a conditional commitment for a proposed loan of up to US$700 million from the US Department of Energy to support the development of Rhyolite Ridge 5 On 27 October 2021, Sibanye-Stillwater entered into a subscription agreement with Century Resources Limited incorporated in Australia (and listed on the ASX), where the Group agreed to purchase ordinary shares as part of a capital raising by Century. The aggregate investment represented a 19.9% ownership interest at 31 December 2022. The Group acquired a 100% shareholding in Century during 2023 (see note 11.1) 6 On 22 March 2022, the Group, through its wholly-owned subsidiary, Sibanye Battery Metals Proprietary Limited, invested in Verkor by subscribing for a €25 million (R409 million) convertible bond. Verkor is a French Gigafactory project aiming to enter the European battery materials market as a manufacturer of low-carbon footprint batteries for application in electric vehicles and large-scale stationary storage markets. The convertible bond was converted into preference shares during September 2023. The convertible bond was recognised as an investment measured at fair value, with net gains and losses recognised in profit or loss. Subsequent to conversion, the preference shares continue to be measured at fair value through profit or loss. During September 2023, the Group also subscribed for a further €15 million (R303 million) preference share investment, which is measured at fair value through profit or loss. The fair value of the total investment in Verkor amounted to R951 million at 31 December 2023 (2022: R554 million), with R93 million (2022: R145 million) recognised as a fair value gain for the year ended 31 December 2023 11. Acquisitions and shareholder transactions 11.1 Century business combination On 21 February 2023, Sibanye-Stillwater announced the launch of an off-market takeover offer, through its wholly-owned subsidiary Sibanye Resources Australia Proprietary Limited, at A$1.10 cash consideration per share for all the shares in Century that Sibanye-Stillwater did not own. Century is an Australian base metal producer with zinc assets and a brownfield copper development project, which operates Australia's largest hydraulic mine at the Century Mine in Queensland, extracting, processing and marketing zinc recovered from historical tailings. The takeover is in line with the Group’s strategy to invest in the circular economy and to be a global leader in tailings retreatment and recycling. Prior to the takeover offer, Sibanye-Stillwater was the largest shareholder in Century with a shareholding of 19.9%. On 22 February 2023, Sibanye-Stillwater obtained a controlling shareholding of 50.15% in Century through the on-market purchase of shares, therefore being the effective acquisition date. Century's financial results were consolidated from the effective date. For the ten months ended 31 December 2023, Century contributed revenue of R2,251 million (A$184 million) and a net loss of R4,767 million (A$377 million) to the Group's results. Century's pro forma revenue and net loss would have been R3,085 million (A$253 million) and R5,062 million (A$403 million), respectively, had the acquisition been effective from 1 January 2023. In determining these amounts, management assumed that the fair value adjustments that arose on the date of acquisition would have been the same if the acquisition had occurred on 1 January 2023. The functional currency of Century is the Australian dollar. The purchase price allocation on the effective date was prepared on a provisional basis in accordance with IFRS 3 Business Combinations (IFRS 3) for, amongst others, property, plant and equipment, contingent liabilities, provisions, as well as any deferred tax implications. If new information obtained within one year of the acquisition date, about facts and circumstances that existed at the acquisition date, identifies adjustments to the below amounts or any additional provisions that existed at the date of acquisition, then the accounting for the acquisition will be revised.

Subsequent shareholder transactions Sibanye-Stillwater acquired additional shares in Century through its original take-over offer subsequent to the effective date of the acquisition. On 10 May 2023, Sibanye-Stillwater, through on-and off-market trades, obtained a 100% interest in Century through cash consideration paid of A$74 million (R906 million) for the additional 49.85% interest in Century. The table below illustrates the effect of the remaining interest acquired in Century on equity attributable to the owners of Sibanye-Stillwater for the year ended 31 December 2023: Figures in million – SA rand 2023 Consideration paid for acquiring the remaining 49.85% interest in Century (906) Carrying value of NCI 914 Total impact on equity attributable to owners of Sibanye-Stillwater1 8 1 The amount includes R13 million increase on accumulated profit and R5 million decrease on other reserves in respect of foreign currency translation reserve 11.2 Transactions with Keliber shareholders On 25 April 2023 the Finnish Minerals Group increased its holding in Keliber from 14% to 20% by subscribing for EUR53.9 million (R1,096 million) of a EUR104 million rights issue. The Group's portion of the subscription (through wholly-owned subsidiary, Keliber Lithium Proprietary Limited) amounted to EUR50.2 million (R1,009 million), which is eliminated on a Sibanye-Stillwater Group level. In addition to the rights issue, other minority shareholders in Keliber (which held 0.79% of the total Keliber shareholding) for which the Group previously recognised an accelerated put option liability at 31 December 2022, received and accepted voluntary offers at the same share price (EUR157.28 per share) as the voluntary offer that concluded in 2022. A total payment of EUR5.2 million (R103 million) was made by the Group to all the shareholders who accepted the voluntary offers during June 2023. Following these transactions, the Finnish Minerals Group holds 20% in Keliber, the Group retained 79.82%, while other minority shareholders hold the balance of the shares in Keliber. The table below summarises the above transactions that occurred during 2023 and the impact thereof on the equity attributable to the owners of Sibanye-Stillwater: Figures in million – SA rand 2023 Rights issue and voluntary offers Cash consideration paid on rights issue subscription by the Group (1,009) Payment eliminated on consolidation 1,009 Cash consideration received from rights issue subscription by NCI 1,096 Cash consideration paid by the Group to NCI on voluntary offer (103) Net cash received by the Group 993 Net reattribution of equity (accumulated profit and foreign currency translation reserve) (596) Net increase in equity attributable to the owners of Sibanye-Stillwater as a result of the transactions with Keliber shareholders 397 Increase in accumulated profit 463 Decrease in foreign currency translation reserve (66) Increase in NCI 700 Net increase in total equity as a result of the transactions with Keliber shareholders 1,097 11.3 Kroondal business combination On 31 January 2022, Sibanye-Stillwater announced that, through its subsidiary Sibanye Rustenburg Platinum Mines Limited (SRPM), it had entered into an agreement with RPM a subsidiary of Anglo American Platinum Limited (AAP), whereby the Group would assume full ownership of the Kroondal operation with SRPM acquiring RPM's 50% ownership in the pool and share agreement (Kroondal PSA) between Kroondal Operations Proprietary Limited (wholly-owned subsidiary of the Group) and RPM. On 1 November 2023, Sibanye-Stillwater announced that the transaction had been brought forward and all conditions precedent had either been met or waived in order for SRPM to acquire RPM's 50% share in the Kroondal PSA effective 1 November 2023 (acquisition date). The implementation of the transaction (as announced on 31 January 2022) was subject to key conditions precedent such as the relevant regulatory approvals and required consent to transfer RPM's mining right to SRPM. Another key condition precedent was the delivery of 1,350,000 4E ounces by the Kroondal operation to RPM's designated smelters through the mining of both the Kroondal PSA orebody and SRPM orebody and the Klipfontein open pit operation. In order to expedite the transaction, this condition was waived in return for SRPM paying a contingent consideration to RPM until the full agreed number of ounces are delivered, which is expected to conclude in Q2 2024. The transaction also includes a contingent payment related to the mining of the Merensky Reef mining area, however since Sibanye-Stillwater currently does not plan to mine this area, no consideration was included as part of the business combination. OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 35 'b G < > - The conclusion of this transaction allows for the Group to extend the Kroondal operation's operating life, which was constrained by the existing Kroondal PSA and which has been transferred to SRPM on the effective date of the transaction. The Group will be able to realise the true potential of the adjacent resources by utilising the mechanised and low-cost Kroondal operation to mine across the boundary with SRPM and accelerate the extraction of more remote areas of the SRPM orebody, which is expected to sustain employment in the Group and ensure the creation of significant value. Kroondal's financial results were fully consolidated from the effective date. For the two months ended 31 December 2023, Kroondal contributed revenue of R1,006 million and a net profit of R609 million (includes a gain on acquisition of R898 million) to the Group's results. Kroondal's pro forma revenue and net profit would have been R8,120 million and R1,387 million (includes a gain on acquisition of R898 million), respectively, had the acquisition been effective from 1 January 2023. In determining these amounts, management assumed that the fair value adjustments that arose on the date of acquisition would have been the same if the acquisition had occurred on 1 January 2023. The functional currency of Kroondal is SA rand. The purchase price allocation on the effective date was prepared on a provisional basis in accordance with IFRS 3 for, amongst others, property, plant and equipment, contingent liabilities, provisions, as well as any deferred tax implications. If new information obtained within one year of the acquisition date, about facts and circumstances that existed at the acquisition date, identifies adjustments to the below amounts or any additional provisions that existed at the date of acquisition, then the accounting for the acquisition will be revised. Consideration The fair value of the consideration, including previous interest held is as follows: Figures in million – SA rand 2023 Cash consideration -* Fair value of previously held interest1 2,354 Total contingent consideration 1,433 Contingent consideration related to delivery of agreed ounces2 333 Contingent consideration related to AAP receivable portion3 1,100 Total consideration 3,787 * Cash consideration of R1 1 The fair value of the previously held interest in the Kroondal joint operation includes cash and cash equivalents of R489 million. The remeasurement of the Group's previous interest in Kroondal resulted in a gain of R298 million, which is included in other income (see note 6.2) 2 Sibanye-Stillwater agreed to pay RPM a contingent consideration based on a percentage of the cumulative pre-tax cash flows of the Kroondal PSA (effective 1 November 2023) until the total 1,350,000 4E ounces (on a 100% basis) are delivered to RPM (agreed PSA ounces). At the effective date, approximately 204,517 4E ounces were still outstanding in terms of the Kroondal PSA and will continue to be delivered under the terms of the purchase of concentrate (PoC) arrangement. The percentage is determined based on a sliding scale/specific ranges of the PGM basket price included in the sale agreement. Sibanye-Stillwater will not make any payment to RPM if the cumulative pre-tax cash flows of the Kroondal PSA is negative. The contingent consideration at the effective date was calculated using an average 4E PGM basket price of R20,703/4Eoz and a discount rate of 10.76%. A 10% change in the average 4E PGM basket price will result in an undiscounted R127 million change to the contingent consideration. The contingent consideration is subsequently measured at fair value with movements recognised in profit or loss. The liability at 31 December 2023 amounted to R300 million with a fair value gain of R33 million recognised in profit or loss (see note 15) 3 Sibanye-Stillwater agreed to pay RPM an amount equal to 50% of the amount receivable from RPM at the end of the final measurement period in respect of the agreed PSA ounces in footnote 2 above (agreed PSA ounces receivable). The amount receivable relates to a Kroondal PSA PGM concentrate sale agreement between Sibanye- Stillwater and RPM. RPM will withhold 50% of each payment of the agreed PSA ounces receivable until the payment is made in full. Sibanye-Stillwater determined the contingent consideration at effective date as 50% of the agreed PSA ounces receivable and was calculated using an average 4E PGM basket price of R22,495/4Eoz and a discount rate of 10.76%. A 10% change in the average 4E PGM basket price will result in an undiscounted R123 million change to the contingent consideration. The contingent consideration is subsequently measured at fair value with movements recognised in profit or loss. The contingent consideration liability at 31 December 2023 amounted to R1,270 million with a fair value loss of R170 million recognised in profit or loss (see note 15) Acquisition related costs The Group incurred total acquisition related costs of R3 million for the year ended 31 December 2023 on advisory and legal fees. These costs are recognised as transaction costs in profit or loss during the period in which incurred.

Historically, and up to delivering the last agreed PSA ounce to RPM (expected June 2024), the delivered agreed PSA ounces included SRPM ounces mined outside of the Kroondal PSA area, resulting in reduced ounces being mined from the PSA area. The remaining PSA reserves are included in the valuation of the business combination and is the primary reason for the gain on acquisition. 11.4 Copper Mines of Tasmania Proprietary Limited (CMT) asset acquisition On 1 November 2023, Sibanye-Stillwater announced that it had exercised its option to acquire a 100% shareholding, for a consideration of US$10 million (R186 million), in CMT which owns the Mt Lyell copper mine in Tasmania, Australia. Sibanye-Stillwater obtained the option to acquire CMT from Vedanta Limited, as part of the Group's acquisition of Century in 2023 (see note 11.1). Mt Lyell is a previously operated underground copper mine which commenced production in 1894 and operated until it was put on care and maintenance in 2014. This transaction will potentially provide the Group with low cost exposure to copper, which has been identified as an essential metal necessary to enable the clean energy transition. Mt Lyell will also potentially add primary production of copper to the Group's current lithium and nickel exposure. A feasibility study, which considers the re-establishment of the operation is underway. At the date of acquisition (17 November 2023), CMT did not meet the definition of a business in terms of IFRS 3, and is therefore accounted for as an asset acquisition. Allocation of purchase consideration Since the acquisition is outside the scope of IFRS 3, the purchase consideration was allocated to identifiable assets and liabilities based on their relative fair values. Assets and liabilities that are initially measured at an amount other than cost, such as financial instruments recognised at fair value, were recognised at their respective carrying amounts as specified in the applicable accounting standards. The functional currency of CMT is the Australian dollar.

The new facility is a minimum US$1 billion RCF for a period of three years, subject to two optional one-year extensions (3+1+1). The facility is linked to a Secured Overnight Financing Rate (SOFR), which is a recently effective interest rate published as part of the IBOR reform initiative. On 26 March 2024, all facility lenders approved the first extension with the facility maturing on 6 April 2027 2 The Burnstone debt and the R5.5 billion RCF are affected by the amendments to IFRS 9 Financial Instruments relating to interest rate benchmark reform, in particular the replacement of interbank offered rates (IBORs), which came into effect on 1 January 2021. However, the R5.5 billion RCF is linked to JIBAR and is only expected to be impacted by the IBOR reform at a later stage and any impact thereof will be considered when this occurs. The Burnstone debt is linked to a US LIBOR and the Group is in process to transition the debt facility to a new interest rate. The impact on the Burnstone debt due to IBOR reform at 31 December 2023 is unknown and will be assessed when further detail is available in respect of the transition to a new interest rate US$500 million Convertible Bond Sibanye-Stillwater (through its wholly-owned subsidiary Stillwater Mining Company (Stillwater)) launched an offering of US$500 million senior, unsecured, guaranteed bonds, due in November 2028 and subject to the receipt of the requisite approval by a general meeting of the shareholders of Sibanye-Stillwater, will be convertible into new and/or existing Sibanye-Stillwater ordinary shares (Convertible Bonds). Prior to, and/or absent of such approval, holders of the Convertible Bonds will, on conversion, receive a cash amount equal to the value of the underlying ordinary shares. The proceeds of the bonds will be applied to the advancement of the Group's growth strategy including the funding of future acquisitions, whilst preserving the current balance sheet for funding existing operations and projects through a lower commodity price environment. Terms of the US$500 million Convertible Bond Issue size: US$500 million Coupon: 4.25% Maturity date: 28 November 2028 (five years) Conversion premium: 32.5% Reference share price: US$1.0088 (R18.55), being the volume weighted average price of Sibanye-Stillwater's shares listed on the JSE Limited between opening of trading and close of trading on 21 November 2023, converted into US$ at R18.388/US$ Initial conversion price: US$1.3367 Issuer: Stillwater Guarantors: The Company, SGL, Kroondal, SRPM, Eastern Platinum Proprietary Limited, Western Platinum Proprietary Limited The US$ Convertible Bond consists of two components. The option component is recognised as a derivative financial instrument (financial liability), measured at fair value, with changes in fair value recognised in profit or loss. The non-derivative host instrument (i.e. bond component) is recognised as a financial liability measured at amortised cost using the effective interest method. If shareholder approval is obtained for the share conversion option, the derivative element will be reclassified to equity. In addition, the bond component and derivative financial instrument will be fully classified as current liabilities while shareholder approval for the conversion option remains outstanding since bondholders are entitled to call for settlement in cash to the value of Sibanye-Stillwater shares at any time from 8 January 2024 up until shareholder approval for the share conversion option is obtained.

Due to sustained losses incurred at the operation, the Group assessed whether the supply contract is onerous at the reporting date. Consequently, the Group determined whether the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfil it. Based on this assessment, the Group recognised an onerous contract provision amounting to R1,865 million, which represents the present value at 31 December 2023 of the penalty payable on early exiting the supply contract and the unavoidable losses to be incurred in meeting Sandouville's obligations under the contract during the notice period. Before the separate provision for the onerous contract was established, the Group recognised an impairment loss on assets, partially dedicated to the contract (see note 7 ). The onerous contract provision was calculated based on an expectation of terminating the contract in line with the required notice period and discounted at a pre-tax rate of 5.75%, reflecting the risks specific to the provision 2 The current portion at 31 December 2023 relates to the onerous contract provision OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 41 'b G < > - 14.

A dividend obligation was recognised for the NCI of Keliber on the effective date of the agreement (25 April 2023) at R792 million, with a corresponding reduction in NCI. The Group's attributable portion of the dividend obligation eliminates on consolidation. The dividend obligation is a financial liability and was initially measured at fair value less any directly attributable costs, and subsequently measured at amortised cost. At 31 December 2023 the following assumptions were applied in measuring the Keliber dividend obligation: 2023 2022 2021 Average lithium hydroxide price US$/t 22,933 — — Real discount rate % 9.83 — — Inflation rate % 2.0 — — Life-of-mine years 24 — — The following table summarises the changes in the Keliber dividend obligation: Figures in million – SA rand Note 2023 2022 2021 Balance at the beginning of the year — — — Initial recognition of the Keliber dividend obligation 792 — — Loss on revised estimated cash flows1 5 287 — — Interest — unwinding of amortised cost 52 — — Foreign currency translation reserve 16 — — Balance at end of the year 1,147 — — 1 The loss on revised estimated cash flow is primarily as a result of an increase in the average lithium hydroxide price OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 43 'b G < > - Fair value of other payables The fair values other payables approximate the respective carrying values, except for the Marikana dividend obligation and the Keliber dividend obligation. At 31 December 2023, the fair values (level 3) of the Marikana dividend obligation and the Keliber dividend obligation amounted to R1,257 million and R1,434 million, respectively. The fair values at 31 December 2023 were calculated by applying a market- related discount rate to expected future cash flows available for dividends. At 31 December 2022 and 31 December 2021, the Marikana dividend obligation's carrying value approximated fair value.

Financial instruments and risk management 16.1 Measurement of fair value The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments: • Level 1: unadjusted quoted prices in active markets for identical asset or liabilities • Level 2: inputs other than quoted prices in level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices) • Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs) The following table sets out the Group’s significant financial instruments measured at fair value by level within the fair value hierarchy: Figures in million - SA rand 2023 2022 2021 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Financial assets measured at fair value Environmental rehabilitation obligation funds1 5,080 847 — 4,528 778 — 4,477 725 — Trade receivables — PGM concentrate sales2 — 3,407 — — 3,564 — — 3,794 — Trade receivables — Zinc provisional price sales2 — 108 — — — — — — — Other investments3 1,652 — 1,233 2,320 — 855 3,143 — 224 Asset held for sale4 — — — — — — — 280 — Palladium hedge contract5 — — — — 50 — — 286 — Financial liabilities measured at fair value Derivative financial instrument5 — 3,810 — — — — — — — Gold hedge contracts5 — 140 — — — — — — — Zinc hedge contracts5 — 33 — — — — — — — Contingent consideration6 — — 1,570 — — — — — — 1 Environmental rehabilitation obligation funds comprise fixed income portfolio of bonds as well as fixed and notice deposits. The environmental rehabilitation obligation funds are stated at fair value based on the nature of the fund’s investments. The fair value of publicly traded instruments is based on quoted market values 2 The fair value for trade receivables measured at fair value through profit or loss (PGM concentrate sales and zinc provisional price sales) are determined based on ruling market prices, volatilities and interest rates 3 The fair values of listed investments are based on the quoted prices available from the relevant stock exchanges. The carrying amounts of other short-term investment products with short maturity dates approximate fair value. The fair values of non-listed investments are determined through valuation techniques that include inputs that are not based on observable market data. These inputs include price/book ratios as well as marketability and minority shareholding discounts which are impacted by the size of the shareholding. The level 3 balance consists primarily of an investment in Verkor, which is valued based on a recent share subscription price recently determined by market participants and since Verkor is a pre-revenue operation still in development, the subscription price is considered a reasonable approximation of fair value. The difference between other investments in the statement of financial position and the table above, relates to investments measured at amortised cost, with carrying amounts that approximate fair value 4 The fair value of the asset held for sale was derived from the quoted Generation Mining Limited share price 5 The fair value of derivative financial instruments is estimated based on ruling market prices, volatilities and interest rates, and option pricing methodologies based on observable quoted inputs. All derivatives are carried on the statement of financial position at fair value. The fair value of the gold and palladium hedge is determined using a Monte Carlo simulation model based on market forward prices, volatilities and interest rates. The fair value of the zinc hedge is determined by calculating the delta of the relevant forward curves relating to the fixed and floating elements of the swaps, and discounting the result using a market-related discount rate 6 The fair value of the contingent consideration relating to the Kroondal acquisition has been derived from discounted cash flow models. These models use several key assumptions, including estimates of future production volumes, PGM basket prices, operating costs, capital expenditure and market related discount rate). The fair value estimate is sensitive to changes in the key assumptions (see note 10.3). The extent of the fair value changes would depend on how inputs change in relation to each other OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 44 'b G < > - The below table summarises the movement in financial assets and financial liabilities classified as level 3 in the table above: Figures in million - SA rand 2023 2022 2021 Financial assets measured at fair value Balance at beginning of the year 855 224 244 Fair value movement recognised in profit or loss 108 152 — Fair value movement recognised in other comprehensive income (59) (8) (29) Additions 323 483 — Foreign currency translation 6 4 9 Balance at end of the year 1,233 855 224 Financial liabilities measured at fair value Initial recognition 1,433 — — Fair value movement recognised in profit or loss 137 — — Balance at end of the year 1,570 — — Fair value of borrowings The carrying amounts of variable interest rate borrowings approximates fair value as the interest rates charged are considered market related.

As at 31 December 2023, the Group’s current assets exceeded its current liabilities by R25,415 million (2022: R40,545 million and 2021: R44,290 million) and the Group’s total assets exceeded its total liabilities by R51,607 million (2022: R91,004 million and 2021: R81,345 million). During the year ended 31 December 2023 the Group generated net cash from operating activities of R7,095 million (2022: R15,543 million and 2021: R32,256 million). The Group has committed undrawn debt facilities of R20,755 million at 31 December 2023 (2022: R16,403 million and 2021: R15,749 million) and cash balances of R25,560 million (2022: R26,076 million and 2021: R30,292 million). The Group concluded the refinancing of its US$600 million RCF to a US$1 billion RCF during 2023, and the most immediate debt maturity is the R5.5 billion RCF maturing in November 2024. During November 2023, the Group launched an offering of US$500 million senior, unsecured, guaranteed convertible bonds, due in November 2028, which will be applied to the advancement of the Group's growth strategy including the funding of future acquisitions, whilst preserving the current balance sheet for funding existing operations and projects through a lower commodity price environment. The bonds, subject to approval by a general meeting of Sibanye-Stillwater shareholders, will be convertible into existing or new ordinary shares. Until such approval OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 45 'b G < > - is obtained, holders of the bonds will, on conversion, receive a cash amount equal to the value of the underlying ordinary shares, and therefore at 31 December 2023 the Convertible Bond and associated derivative financial instrument are classified as repayable within twelve months. Sibanye-Stillwater’s leverage ratio (net debt/(cash) to adjusted EBITDA) as at 31 December 2023 was 0.58:1 (2022 was (0.14):1 and 2021 was (0.17):1) and its interest coverage ratio (adjusted EBITDA to net finance charges/(income)) was 66:1 (2022 was 93:1 and 2021 was (5,281):1). Both considerably better than the maximum permitted leverage ratio of at most 2.5:1 and minimum required interest coverage ratio of 4.0:1, calculated on a quarterly basis, required under the US$1 billion RCF and the R5.5 billion RCF. At the date of approving these consolidated financial statements there were no significant events which had a significant negative impact on the Group’s strong liquidity position. Notwithstanding the strong liquidity position and financial outlook, events such as a further decline or prolonged low commodity market, shaft incidents, natural disaster events and other operational related incidents could impose restrictions on all or some of our operations. Events such as these could negatively impact the production outlook and deteriorate the Group’s forecasted liquidity position, which may require the Group to further increase operational flexibility by adjusting mine plans and reducing capital expenditure. This is encouraged by a disciplined application of the Group's Capital allocation framework, which is essential to operational excellence and long-term value creation. This enables the Group to adhere to sound financial decision-making structures and mechanisms to manage costs and ensure long-term sustainability. The Group could also, if necessary, consider options to increase funding flexibility which may include, amongst others, additional loan facilities or debt capital market issuances, streaming facilities, prepayment facilities or, if other options are not deemed preferable or achievable by the Board, an equity capital raise. The Group could also, with lender approval, request covenant amendments or restructure facilities as appropriate. During past adversity management has successfully implemented similar actions. Management believes that the cash on hand, the committed unutilised debt facilities, additional funding opportunities and if required, delaying development expenditure will enable the Group to continue to meet its obligations as they fall due for a period of at least eighteen months after the reporting date. The summarised consolidated financial statements for the year ended 31 December 2023, therefore, have been prepared on a going concern basis. 17. Dividends Dividend policy Sibanye-Stillwater’s dividend policy is to return at least 25% to 35% of normalised earnings to shareholders and after due consideration of future requirements the dividend may be increased beyond these levels. The Board, therefore, considers normalised earnings in determining what value will be distributed to shareholders. The Board believes normalised earnings provides useful information to investors regarding the extent to which results of operations may affect shareholder returns. Normalised earnings is defined as earnings attributable to the owners of Sibanye-Stillwater excluding gains and losses on financial instruments and foreign exchange differences, impairments, gain/loss on disposal of property, plant and equipment, occupational healthcare expenses, restructuring costs, transactions costs, share-based payment expenses on B-BBEE transactions, gain on acquisitions, net other business development costs, share of results of equity-accounted investees, all after tax and the impact of NCI, and changes in estimated deferred tax rate. In line with Sibanye-Stillwater’s dividend policy and its Capital Allocation Framework, the Board of Directors resolved not to declare a final dividend (2022: 122 and 2021: 187 SA cents per share). With the interim dividend of 53 (2022: 138 and 2021: 292) SA cents per share, which was declared and paid, this brings the total dividend for the year ended 31 December 2023 to 53 (2022: 260 and 2021: 479) SA cents per share. The interim dividend amounted to a payout of 35% of normalised earnings for H1 2023 (2022 and 2021, both 35% of normalised earnings for the year). The table below illustrates the dividends declared and paid: Figures in million – SA rand unless stated otherwise 2023 2022 2021 Dividend declared and paid (interim) 1,501 3,905 8,347 Dividend declared after 31 December (final) — 3,452 5,252 Total dividends declared for the year 1,501 7,357 13,599 Dividend per share (interim) — cents 53 138 292 Dividend per share (final) — cents — 122 187 Dividends paid during the financial year 4,953 9,197 17,832 Dividends paid to NCI of subsidiaries during the financial year 365 256 344 Total dividends paid for the year1 5,318 9,453 18,176 1 The dividends paid is influenced by the number of shares in issue at the time of payment OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION NOTES TO THE SUMMARISED CONSOLIDATED FINANCIAL STATEMENTS continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 46 'b G < > -

Contingent liabilities/assets Notice from Appian Capital to commence legal proceedings On 26 October 2021, Sibanye-Stillwater entered into share purchase agreements to acquire the Santa Rita nickel mine and Serrote copper mine (the Atlantic Nickel SPA and the MVV SPA, respectively) from affiliates of Appian Capital Advisory LLP (Appian). Subsequent to signing the agreements, Appian informed Sibanye-Stillwater that a geotechnical event occurred at the Santa Rita open pit operation. After becoming aware of the geotechnical event, Sibanye-Stillwater assessed the event and its effect and concluded that the event was and was reasonably expected to be material and adverse to the business, financial condition, results of operations, the properties, assets, liabilities or operations of Santa Rita. Accordingly, pursuant to the terms of the Atlantic Nickel SPA, on 24 January 2022, Sibanye-Stillwater gave notice of termination of the Atlantic Nickel SPA. As the MVV SPA was conditional on the closing of the Atlantic Nickel SPA, which had become impossible to satisfy, on the same date Sibanye-Stillwater also gave notice of termination of the MVV SPA. On 27 May 2022, Appian initiated legal proceedings before the High Court of England and Wales against Sibanye-Stillwater. On 3 August 2022, the Group filed its defence. Sibanye-Stillwater’s view is that the Atlantic Nickel SPA and the MVV SPA were rightfully terminated and the Group intends to strongly defend the proceedings. The trial is set to begin in June 2024, with the remaining steps to trial taking place in the lead up to June 2024. The proceedings are progressing and additional information and estimates of potential outcomes are unavailable. US PGM insurance claim During H1 2022, the US PGM operations was affected by a significant flood event, which caused the suspension of operations and consequently a loss of production. As a result of the losses incurred, a business interruption and property damage claim was lodged with the insurer. Following the assessment process, the Group believes it is probable that a reimbursement of approximately US$44 million for the business interruption and US$18 million for property damage will be received during 2024. After the reporting date and up to 22 April 2024, the Group received US$40 million relating to the business interruption claim.

Events after the reporting date There were no events that could have a material impact on the financial results of the Group after 31 December 2023 up to the date on which the summarised consolidated financial statements for the year ended 31 December 2023 were authorised for issue, other than summarised below. 19.1 Reldan acquisition On 9 November 2023, Sibanye-Stillwater announced that it had entered into a purchase agreement to acquire 100% of the Reldan group of companies (Reldan). Reldan is a Pennsylvania-based recycling group which processes various waste streams, including industrial waste (semiconductor scrap, plating waste, etc.) and electronic waste (mobile phones, tablets, etc.) to recycle green precious metals. In addition to its US operations, Reldan has established a presence in Mexico and India, where it has forged strategic joint ventures with local partners. At 31 December 2023, certain conditions precedent were still outstanding and the transaction was therefore not effective at the reporting date. The final conditions precedent were fulfilled on 15 March 2024, being the effective date of the transaction. Management is in the process of identifying and measuring the assets and liabilities in accordance with IFRS 3 for, amongst others, property, plant and equipment, contingent liabilities, inventory, provisions, as well as any deferred tax implications. The acquisition was conducted at an enterprise value of US$211.5 million (R3,961 million), with a cash consideration paid of US$155.9 million (R2,920 million). * At an exchange rate at 15 March 2024 of R18.73/US$ 19.2 Section 189 consultations — proposed restructure of SA region On 11 April 2024, Sibanye-Stillwater announced that it will enter a consultation process in terms of Section 189A of the Labour Relations Act, 66 of 1995 (S189) with organised labour and other representatives of affected stakeholders, regarding the proposed restructuring of the Group's SA gold operations and its SA region services functions. Further to previous restructuring concluded during 2023 and Q1 2024, the ongoing Group business review has identified a need to address losses at the Beatrix 1 shaft and the Kloof 2 plant. The deferral of capital expenditure at the Burnstone project also requires restructuring aligned with the reduction in planned capital activities (see note 7). The reduction in the operational footprint in the SA region has resulted in the capacity of the direct and shared services functions for the SA region and operations being surplus to current and future requirements. As a result, Sibanye-Stillwater proposed a re-alignment of the regional services, shared services and direct services structures to align with the requirements of the reduced operational footprint. The proposed restructure of the operations and services could potentially affect 3,107 employees and 915 contractors.

The Board delegated to the Audit Committee the authority to recommend the appointment of an audit firm and the designated individual audit partner to the Board, which would then make a recommendation to the shareholders in the notice of AGM. Following a detailed review, which included an assessment of its independence, the Audit Committee and the Board of the Company has recommended that Ernst & Young Inc. be re-appointed as the auditors of the Company and the individual auditor, being Allister Carshagen. In compliance with section 23 of the Sarbanes-Oxley Act and Section 92 of the Companies Act 71 of 2008 , the incumbent individual auditor, being Lance Ian Neame Tomlinson, is due for partner rotation after acting as the individual auditor for a five year term and will retire at the AGM. The Audit Committee assessed the suitability for appointment of Allister Carshagen as the individual auditor. Based on the results of the Auditor Suitability Review and a review of the independence of Ernst & Young Inc. and the individual auditor, the Audit Committee has satisfied itself in terms of paragraphs 3.84(g)(iv)and 3.87 of the JSE Listings Requirements and recommended to the Board that Ernst & Young Inc. be re-appointed as the auditors of the Company and that Allister Carshagen be appointed as the individual auditor. The Board concurred with the recommendation. ORDINARY RESOLUTION NUMBERS 2 TO 5 Election and re-election of directors In terms of the Company’s Memorandum of incorporation, one third of the directors shall retire from office each AGM. The directors to retire at each AGM shall firstly be vacancies filled or additional directors appointed since the last AGM and then those who have been longest in office since their last election. Retiring directors shall be eligible for re-election. The Board, through the Nominating and Governance Committee, has evaluated the past performance and contribution of the retiring directors and recommends that they be re-elected. ORDINARY RESOLUTION NUMBERS 6 TO 9 Election of members of the Audit Committee The members of the Audit Committee have been nominated by the Board for election as members of the Company’s Audit Committee in terms of section 94(2) of the Act and in terms of the JSE Listings Requirements. The Board has reviewed the proposed composition of the Audit Committee against the requirements of the Act and the Regulations under the Act and in terms of the JSE Listings Requirements and has confirmed that, if all the individuals referred to above are elected, the committee will comply with the relevant requirements and have the necessary knowledge, skills and experience to enable it to perform its duties in terms of the Act and the JSE Listings Requirements. ORDINARY RESOLUTION NUMBER 10 Approval for the issue of authorised but unissued ordinary shares In terms of the Company’s Memorandum of incorporation, read with the JSE Listings Requirements, the shareholders of the Company may authorise the directors to, inter alia, issue any unissued ordinary shares and/or grant options over them, as the directors in their discretion deem fit. The existing authority granted by the shareholders at the previous AGM is proposed to be renewed at this AGM. The authority will be subject to the provisions of the Act and the JSE Listings Requirements. The aggregate number of ordinary shares capable of being allotted and issued in terms of this resolution, other than in terms of the Company’s share or other employee incentive schemes, shall be limited to 5% (five per cent) of the number of ordinary shares in issue as at the date of notice of the AGM. The directors have agreed to seek annual renewal of this authority in accordance with best practice. The directors have no current plans to make use of this authority but wish to ensure that, by having it in place, the Company has some flexibility to take advantage of any business opportunities that may arise in the future.

ORDINARY RESOLUTION NUMBER 11 Issuing of equity securities for cash In terms of ordinary resolution number 10, the Shareholders authorise the directors to allot and issue a portion of the authorised but unissued shares, as the directors at their discretion deem fit. In terms of the JSE Listings Requirements, when shares are issued, or considered to be issued, for cash (including the extinction of any liability, obligation or commitment, restraint, or settlement of expenses), the Shareholders must authorise such issue with a 75% (seventy-five per cent) majority of entitled votes. Related parties have the ability to participate in the allotment and issue of shares for cash provided certain provisions as prescribed in the JSE Listings Requirements and outlined in resolution 10 are met. The authority will be subject to the provisions of the Act and the JSE Listings Requirements. The aggregate number of ordinary shares capable of being allotted and issued for cash are limited as set out in the resolution. The directors consider it advantageous to obtain this authority to provide the Company with flexibility to take advantage of any business opportunity that may arise in future. ORDINARY RESOLUTIONS NUMBERS 12 AND 13 Non-binding advisory vote on Remuneration policy and Implementation reports In terms of the JSE Listings Requirements and King IV Report on Corporate Governance for South Africa 2016 (King IV), the Company’s Remuneration policy and related Implementation report must be tabled every year for separate non-binding advisory votes by the shareholders of the Company at the AGM. In the event that either ordinary resolution number 12 or 13 is voted against by 25% or more of the votes exercised on them, the Company shall engage with the dissenting shareholders as set out in the Remuneration policy as well as in the Integrated report 2023. SPECIAL RESOLUTIONS –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– SPECIAL RESOLUTIONS NUMBER 1 and NUMBER 2 Approval for the annual retainer fees for non-executive directors – differing according to whether they are African-residents or non-African-residents Special resolution number 1 is proposed to enable the Company to comply with the provisions of sections 65(11)(h), 66(8) and 66(9) of the Act, which stipulate that remuneration to directors for their service as directors may be paid only in accordance with a special resolution approved by Shareholders. The Board, through the Remuneration Committee, decided not to recommend any increase to the current annual retainer fees given the poor financial and fatality outcomes during 2023. The proposed fees in Special Resolution Number 1 shall apply to those non-executive directors (NEDs) who are resident in Africa - whereas Special Resolution Number 2 sets out a different schedule of fees which is being proposed for international NEDs who are resident outside of Africa. This proposed two-tiered fee scale arises from the need for the Company to be able to attract and retain high calibre international NEDs, especially as the Company’s operations, management and governance becomes progressively more multinational notwithstanding its current South African domicile and primary listing on the JSE. The Board already has two non-African resident NEDs (one in the UK and one in the USA) who are currently under-rewarded when considering international NED fee benchmarking given the application, up until now, of the single Rand-denominated fee scale. In addition, there are at least six long standing South African resident NEDs who will be retiring from the board over the next few years, and it is the Board’s intention to replace several of them with international NEDs who have the relevant experience and expertise suited to the current and developing international strategies of the Company. The applicable comparable fees for international NEDs in the various board and committee roles is typically far higher (when converted to Rand equivalents) than those fees earned by South African resident NEDs in the same roles, despite the NEDs having identical responsibilities, risks and liabilities in their roles. Accordingly, the Board recommends the introduction of this two-tier NED fee scale which is the common practice amongst practically all major JSE-listed companies. Special Resolution Number 1 sets out the NED fee scale applicable to all NEDs resident in Africa. Besides indicating the decision not to recommend any inflationary adjustments / increase for 2024, this schedule also introduces a new retainer fee scale for Investment Committee members. Previously the Investment Committee was only remunerated on an ad hoc basis as and when meetings were called. However, going forward, the Investment Committee has now formally scheduled two meetings per year in the first instance and will have further meetings as and when needed. The fees in Special Resolution No 1 are intended to cover the two scheduled meetings. The ad hoc meeting fees, as set out and proposed in Special Resolution No 3, will cover the fees for any additional Investment Committee meetings that are called during the year. OUR BUSINESS AND LEADERSHIP SUMMARISED FINANCIAL STATEMENTS NOTICE OF ANNUAL GENERAL MEETING ANCILLARY INFORMATION EXPLANATORY NOTES continued SIBANYE-STILLWATER NOTICE OF ANNUAL GENERAL MEETING AND SUMMARISED FINANCIALS 2023 59 'b G < > - SPECIAL RESOLUTION NUMBER 3 Approval for fees applicable to additional Ad Hoc Committee and Board meetings Special resolution number 3 is an adjustment to the ad hoc fee scale that had previously only been applied to the Investment Committee which had no specifically scheduled meetings and only met as and when required (the fee per meeting is the same as for 2023). However, it is proposed to change this arrangement to an ad hoc fee that is applicable to any and all Board or committee meetings that are formally called and required in between the routinely scheduled Board and committee meetings to address matters that are urgent or that require critical attention by the relevant NEDs. SPECIAL RESOLUTION NUMBER 4 Approval of Travel Allowance Special resolution number 4 is proposed as a replacement of the current application of a ‘per diem’ Travel Fee which, over the last year has amounted to a fee of R22,000 per day being paid for each day that non-SA resident non-executive directors are required to be away from their home country while on Sibanye-Stillwater business, plus one additional day for ‘travel time’. It is proposed to replace this per diem Travel Tee with a single flat-rate Travel Fee of US$3 000 per trip for NEDs who are required to travel outside of their country of residence in order to attend company board or committee meetings or to travel on any other approved company business. This Travel Fee is over and above the Company covering the direct costs for travel and accommodation on such trips. SPECIAL RESOLUTION NUMBER 5 Approval for the Company to grant financial assistance in terms of sections 44 and 45 of the Act Notwithstanding the title of section 45 of the Act, on a proper interpretation thereof, the body of the section also applies to financial assistance provided by a company to any related or inter-related company or corporation, a member of a related or inter-related corporation, and to a person related to any such company, corporation or member. This financial assistance required does not and will not extend to the directors of Sibanye-Stillwater and the authority sought will be limited authority for the Company to provide direct or indirect financial assistance to only its present or future subsidiaries and/or any other company or entity that is or becomes related or inter-related to the Company, at any time during a period commencing on the date of passing of this resolution and ending at the next AGM. Further, section 44 of the Act may also apply to the financial assistance so provided by a company to any related or inter-related company or corporation, a member of a related or inter-related corporation, or a person related to any such company, corporation or member, in the event that the financial assistance is provided for the purpose of, or in connection with, the subscription of any option, or any securities, issued or to be issued by that company or a related or inter-related company, or for the purchase of any securities of that company or a related or inter-related company. The authority sought is limited authority for the Company to provide direct or indirect financial assistance to any related or inter-related company or corporation. Both sections 44 and 45 of the Act provide, inter alia, that the particular financial assistance must be provided only pursuant to a special resolution of Shareholders, adopted within the previous 2 (two) years, which approved such assistance either for the specific recipient, or generally for a category of potential recipients, into which the specific recipient falls, and that the Board is satisfied that: (i) immediately after providing the financial assistance, the Company would satisfy the solvency and liquidity test (as contemplated in the Act) and (ii) the terms under which the financial assistance is proposed to be given are fair and reasonable to the Company As part of the normal conduct of the business of the Group, the Company, where necessary, may provide guarantees and other support undertakings to third parties which enter into financial agreements with its subsidiaries and joint ventures or partnerships in which the Company or members of the Group have an interest. In the circumstances and in order to, inter alia, ensure that the Company and its subsidiaries and other related and inter-related companies and entities continue to have access to financing for purposes of refinancing existing facilities and funding their corporate and working capital requirements, it is necessary to obtain the approval of the Shareholders as set out in this special resolution. The Company also requires the ability to continue to provide financial assistance, if necessary, in other circumstances, in accordance with section 45 of the Act. Furthermore, it may be necessary for the Company to provide financial assistance to any of its present or future subsidiaries, and/or to any related or inter-related company or corporation, and/or to a member of a related or inter-related corporation, to subscribe for options or securities of the Company or another company related or inter-related to it. Under the Act, the Company will require the special resolution referred to above to be adopted. It is therefore imperative that the Company obtains the approval of Shareholders in terms of special resolution number 4 so that it is able to effectively organise its internal financial administration. SPECIAL RESOLUTION NUMBER 6 Acquisition of the Company’s own shares Special resolution number 4 is sought to allow the Company and/or its Subsidiaries (the Group) by way of a general authority to acquire its own issued shares (whether in the form of ordinary shares or American depositary shares) (reducing the total number of ordinary shares of the Company in issue in the case of an acquisition by the Company of its own shares). At the present time, the directors have no specific intention regarding the use of this authority which will be used if the circumstances are appropriate. Any decision by the directors to use the general authority to acquire shares of the Company will be taken with regard to prevailing market conditions and other factors.

Section 56 grants voting rights to holders of a beneficial interest in certain circumstances, namely if the beneficial interest includes the right to vote on the matter, and the person’s name is on the Company’s register of disclosures as the holder of a beneficial interest. A person who has a beneficial interest in any securities that are entitled to be voted on by him/her, may demand a proxy appointment from the registered holder of those securities, to the extent of that person’s beneficial interest, by delivering such a demand to the registered holder, in writing, or as required by the applicable requirements of a central securities depository. 2. A proxy appointment must be in writing, dated and signed by the person appointing the proxy. 3. Forms of proxy may be delivered to the Company by or before 9:00 on Friday, 24 May 2024 before a proxy may exercise any voting rights at the AGM by: • hand delivery to Computershare Investor Services Proprietary Limited at Rosebank Towers,15 Biermann Avenue, Rosebank, 2196, or to • Link Asset Services, The Registry, 34 Beckenham Road, Beckenham, Kent, BR3 4TU or • postal delivery to Computershare: Private Bag X9000, Saxonwold, 2132 or • electronic delivery by email to proxy@computershare.co.za 4.

The person whose name stands first on the form of proxy and who is participating at the AGM shall be entitled to act as proxy to the exclusion of the person whose name follows as an alternative. In the event the proxy is given to the Chair without direction or that no proxy names are indicated, the proxy shall be exercised by the Chair of the AGM to vote in favour of any resolution. 6. An “X” in the appropriate box indicates that all your voting rights are exercisable by that holder. If no instructions are provided in the form of proxy, in accordance with the above, then the proxy shall be entitled to vote or abstain from voting at the AGM, as the proxy deems fit in respect of all your voting rights exercisable thereat but, as noted above, if the proxy is the Chair, failure to provide instructions to the proxy in accordance with the above will be deemed to authorise the proxy to vote only in favour of the resolution. 7. You or your proxy are not obliged to exercise all your voting rights that are exercisable, but the total of the voting rights cast may not exceed the total of the voting rights that may be exercised by you. 8. Your authorisation to the proxy, including the Chair of the AGM, to vote on your behalf, shall be deemed to include the authority to vote on procedural matters at the AGM. 9. The completion and lodging of this form of proxy will not preclude you from attending the AGM and speaking and voting in person thereat to the exclusion of any proxy appointed in terms hereof, in which case the appointment of any proxy will be suspended to the extent that you choose to act in person in the exercise of your voting rights at the AGM. 10. The Company’s Memorandum of incorporation does not permit delegation by a proxy. 11. Documentary evidence establishing the authority of a person participating in the AGM on your behalf in a representative capacity or signing this form of proxy in a representative capacity must be attached to this form. 12.

SIBANYE-STILLWATER GROUP IMPACT SUPPLEMENT 2023 1 About our cover designs: Our strategic differentiator Inclusive, diverse and bionic, is depicted in the cover as a fingerprint, with small markings that signify computer code. As technology becomes ever more capable and powerful, the fear exists of the possible loss of human individuality, the loss of our independent spirit. The design reminds us what this strategic differentiator points to, the potential for humanity to be enhanced through using technology (“bionic”), and the potential for uniqueness and diverse individual identity to find its expression in service to our vision and purpose. We value the contributions of our employees (each having left their unique “fingerprint” on our business) and we honour their commitment to our values, which ripples out, amplifying the Group’s capacity to innovate and evolve.

PGMs are mostly sold in the form of refined bars, powder or sponge. Primary uses of PGMs: Autocatalysts Jewellery Chemical industry Glass manufacture Electrical industry Medical applications Gold market Gold ore is processed at the mines’ gold plants to produce doré (unrefined gold bars). The doré is refined by Rand Refinery to a purity of at least 99.5%, in accordance with the London Bullion Market Association’s standards of ‘good delivery’. The refined gold bars are sold directly to international bullion banks. Principal areas of gold demand are: Jewellery, mainly India and China Central banks Investment – mostly institutional, including exchange traded funds Technological applications, especially nanotechnology Century tailings retreatment Sibanye-Stillwater owns and operates the zinc tailings retreatment operation in Queensland, Australia Lithium, nickel and zinc markets Lithium and its compounds have been used in the manufacturing of high-temperate lubricants, high strengh-to-weight alloys, heat-resistant glass and ceramics and in the synthesis of the cathode of lithium-ion batteries. With our Keliber lithium project located in Finland, lithium is a strategic commodity with the growing European end-user battery markets for lithium hydroxide. Our Sandouville nickel processing facility in France is ideally located to serve the European end-user market. Nickel is an essential component in Li-ion batteries, enabling batteries to store greater amounts of energy. Zinc is highly recyclable and can be recovered and reprocessed with very minimal losses. It fits well in our Green metal strategy as zinc coatings play an essential part in protecting solar, wind and energy infrastructure from corrosion. The FTSE Russell green revenue factor; defined by FTSE Russell as the percentage of revenue that is derived from products that have a positive environmental utility which help prevent, restore and/or adapt to issues deriving from climate change, natural resource limitations and environmental degradation. 68% GREEN REVENUE FACTOR A strategic essential for Sibanye-Stillwater is about ESG embedded as the way we do business. By placing sustainability and the UN SDGs at the heart of our value creation efforts, we will be Recognised as a force for good (one of our strategic differentiators). In this regard, highlights for 2023 include conformance to the Global Industry Standard on Tailings Management (GISTM) for very high and extreme consequence tailings storage facilities, and the completion of a detailed climate change scenario analysis. The scenario analysis evaluated the vulnerability of our business down to asset level in terms of physical and transitional risks, and financial impact. This is the ideal foundation for us to develop transformative actions to combat the impacts of climate change, as required by SDG 13. To further drive sustainability, as part of the long-term incentive programme, we have an ESG scorecard. The first ESG scorecard came into effect in 2021 and has progressed to achieve an average of 119,73% for its first three years. Our ESG scorecard drives the reduction of carbon emissions, water management, diversity and inclusion, as well as socioeconomic impacts. The Sibanye Foundation NPC is now established, with donations having been disbursed to positively impact where we operate. To date the total allocation of R212 million has been made. R42 million has been distributed to projects in the SA and EU regions through the Sibanye Foundation NPC, with the aim to promote inclusive societies for sustainable development, as anchored by SDG 16. One of the first projects through the Foundation has given 1,200 children access to adequate sanitation facilities at schools in the Eastern Cape and Limpopo provinces, South Africa. The value we have shared with our communities through socioeconomic development and corporate social investment (CSI) programmes has also increased significantly over the last 11 years, from just over R1 billion (US$109 million) in 2013, to over R2.7 billion (US$146 million) in 2023, a 156% increase. The cumulative value flow to communities over the last 11 years amounts to R17 billion/US$1 billion. Building sustainable development capability throughout Sibanye-Stillwater is key to drive a responsible and transformative culture, but it also enables conversations across the business on what sustainability should look like and, to this end, we have launched Sustainability thought leadership dialogues. The inaugural Sustainability thought leadership dialogue series took place in October 2023, titled “Facilitating a just transition to post-mining economy”. A capacity-building programme in partnership with DukeCE was also launched; with modules focused on embedding ESG as core to the business, and leading in ESG. The Group has continued to grow its global footprint, with the Century operations in Australia also now forming part of this Impact report. We remain a significant employer, supporting a great number of employees and their dependents globally. In 2013, we employed a mere 36,274 people, including contractors, exclusively in South Africa. By 2023, this had increased by 128% to 82,788 worldwide, with the majority of our workforce continuing to be in South Africa. Much work lies ahead, especially closing the gaps identified through our human rights due diligence risk assessments. Our impact priorities for 2024 will be to continue executing our Energy and decarbonisation strategy (investing in renewables to reduce absolute GHG emissions), completing a socioeconomic study for all regions, investing in economic circularity, and leveraging our assets for impact post-mining. This Impact report supplements our Integrated report and other supporting reports, which provide a comprehensive perspective on Sibanye-Stillwater’s economic, social, and environmental performance. It is intended to provide specific coverage of the impact being made by our operations in society through delivery of shared value to all stakeholders. 26 April 2024 OUR GEOGRAPHIC PORTFOLIO OUR PRODUCTS AND MARKETS CHIEF SUSTAINABILITY OFFICER’S MESSAGE CELEBRATING SHARED VALUE SUSTAINABLE DEVELOPMENT GOALS SUMMARY OF IMPACT 2023 IMPACT BY OPERATION GOVERNANCE OF OUR IMPACT SIBANYE-STILLWATER GROUP IMPACT SUPPLEMENT 2023 6 “We recognised the importance of creating superior value for all stakeholders and adopted this as our corporate vision.

Marikana Agri-Hub is a partnership between Sibanye-Stillwater and Mineworkers Development Agency (MDA). It aims to advance socioeconomic development in the Marikana community by implementing diverse agricultural activities such as hydroponics, egg production and crop farming, using sustainable farming practices. Crop rotations, intercropping, the use of organic fertilisers/compost, and low tillage are among the strategies used at the hub to maximize resource efficiency. This helps promote healthy produce, which contributes to communities consuming healthier organic foods, thus supporting UN SDG 12 (Responsible Consumption and Production) and SDG 3 (Good Health and wellbeing). The Marikana Agri-Hub is managed and operated by MDA and has received generous financial contribution from Rand Mutual Assurance, Epiroc, and the Industrial Development Corporation, all of which are part of the Marikana Coalition Compact. The Agri-Hub also hosts the Marikana Social Employment Programme as part of the Presidential Employment Stimulus. Total jobs created in this project is 62, of which 28 are women. The project's purpose is to end the cycle of poverty in rural areas by creating a shared value vertical supply chain for high-value agricultural production systems. The project intends to unlock and use the vast untapped potential of food systems to accelerate rural agro-industrial development, enhance small-scale farmer productivity and income, and generate more sustainable green jobs, food supply and value chains in multiple regions. By providing training, mentoring, and capacity building, the project assists smallholder farmers in becoming self-sufficient. The center integrates and connects multiple smallholder farmers into a larger scheme linked to out-grower programmes with established farms in the surrounding area to release bulk buying power, selling power,, shared access to infrastructure, and market links. MARIKANA REGENERATIVE CENTER OF EXCELLENCE Green jobs created through these projects are not only jobs with a beneficial environmental impact; they promote new skills and employment equity by creating opportunities to filtrate into the labour market. This has been evident in the number of green jobs created to employ the vulnerable communities to enable project beneficiaries to be economically stable and be able to have access to basic needs such as food. These projects have also proved that through innovative solutions, the communities become aware of the environmentally friendly practices which are mandatory on project site to reduce carbon emissions. This responds to SDGs 1, 2, 3, 4, 8 and 12. The project provides training, mentoring, and capacity building. It also assists smallholder farmers in becoming self-sufficient. This responds to SDG 4 by ensuring equitable education and training and promoting lifelong learning.

The shaft has an estimated 260 pieces of trackless mobile machinery (TMMs). During 2023, two employees of Bathopele mine participated in the UN youth innovators programme, deciding to work on SDG 13 (climate action). Bathopele’s main source of scope 1 GHG emissions is diesel consumption. The team assessed the GHG emissions and set-out a detailed project to positively contribute to the SDGs, winning an environmental award from Southern African Institute of Mining and Metals in 2023 for their efforts. Aim of project a. To achieve a decrease in carbon emissions from trackless mobile machinery b. To increase the use of renewable energy c. To create a cleaner and more sustainable shaft d. To demonstrate financial savings through the implementation of innovative solutions Bathopele shaft is already seeking alternatives to diesel-powered machines; battery-electric and hydrogen fuel cells being the alternatives. However, it was through onsite waste management that the team made the greatest contribution to the SDGs. The team identified that waste from underground and surface operations is sorted at the onsite salvage yard, which faced challenges owing to sorting machines and waste bin shortages, delayed disposal trucks and contraventions of the waste sorting procedures. The team implemented fairly simple solutions that had a significant impact. These solutions included the prevention of cross contamination of waste at the salvage yard by introducing waste skips for recyclables, the recycling of old TMMs and machinery components, and the formulation of strategies to prevent water and soil contamination. The team managed to recycle 50% of its hazardous waste through proper waste management practices, saving Bathopele R768,000 per year. They also evaluated the old and used TMMs and the valuation contributed to a R2.2 million saving for the shaft. The total savings opportunity for the first 12 months at Bathopele mine is R3.7 million. REDUCTION OF CARBON EMISSIONS: A WASTE PERSPECTIVE Converting the of hazardous waste to recycling by sorting and value adding activities = R1,537,892 per annum Valuation used/old MM for resale = R 2 214 600 Total saving opportunity for first 12 months at Bathopele mine = R3 752 491 12.5, 13.2 Financial impact of the project SUSTAINABLE DEVELOPMENT GOALS IN ACTION: SDG 4.4 AND SDG 4.6 OUR GEOGRAPHIC PORTFOLIO OUR PRODUCTS AND MARKETS CHIEF SUSTAINABILITY OFFICER’S MESSAGE CELEBRATING SHARED VALUE SUSTAINABLE DEVELOPMENT GOALS SUMMARY OF IMPACT 2023 IMPACT BY OPERATION GOVERNANCE OF OUR IMPACT SIBANYE-STILLWATER GROUP IMPACT SUPPLEMENT 2023 13 SHARED VALUE: PROMOTING LEARNING OPPORTUNITIES Over the past decade, Sibanye-Stillwater has invested more than R2 billion into quality education, distributed across multiple areas, including tertiary study bursaries, learnerships within our operations, graduate internship programmes, portable skills and “cadetships” aimed at enhancing skills in surrounding communities. BURSARIES From 2013 to 2023, Sibanye-Stillwater has enabled 682 individuals through our bursary programme at our SA gold operations and from 2015 to 2023, 394 individuals at our SA PGM operations received a bursary. As bursars complete their studies they access our internship programmes and we saw the absorption of 192* interns into employment at our SA gold operations and 160** interns into employment at our SA PGM operations. Through our bursary programmes we have invested over R141 million***, into some of the top universities in the country and, from 2013 to 2023, the University of Johannesburg has received R29.7 million, North-West University: R12 million, the University of South Africa: R2.4 million, the University of Cape Town: R1.9 million, and the Gordon Institute of Business Science: R24.8 million. Since 2013, Sibanye-Stillwater has invested R32.4 million in educational support at the University of the Witwatersrand (WITS). Through Digimine, we have accomplished 42 research projects, installed 34 systems, and produced ten PHD graduates. In 2023, we awarded additional bursaries to nine top matriculants from disadvantaged schools in communities around our SA operations. The Group launched this bursary scheme in 2019 to provide top performers from disadvantaged schools in host communities with full scholarships to pursue tertiary education. It has benefited 56 learners (30 male and 26 female) since its inception. * Period from 2013–2023; ** Period from 2015–2023; *** Excluding bursary allowances or any other related expenditure not directly payable to the university CADETSHIP PROGRAMME The Cadetship programme provides skills development for unemployed youth in communities surrounding Sibanye- Stillwater’s operations. They are provided with basic skills required to be eligible for employment at entry-level job categories of mining and metallurgy. Since 2018, over R39 million has been spent towards 3,735 cadets. Our Cadetship programme creates an opportunity to expose women to the mining industry, and in 2023, 49% of our cadets were women. INTERNSHIP AND LEARNERSHIP PROGRAMME The Intern graduate development programme provides work-related exposure and professional development for students who are completing or have completed their university studies. The learnership programme aims to increase the employability of young people by providing them with relevant work experience. To this end, Sibanye- Stillwater has provided 9,894 learners with opportunities within mining and engineering and has spent R1.8 billion towards the programme since 2013. HRD spend across the SA operations amounted to 4.4% of total payroll in 2023 (5.1% in 2022). 4.4, 4.6 SUSTAINABLE DEVELOPMENT GOALS IN ACTION: SDG 4.4 AND SDG 4.6 OUR GEOGRAPHIC PORTFOLIO OUR PRODUCTS AND MARKETS CHIEF SUSTAINABILITY OFFICER’S MESSAGE CELEBRATING SHARED VALUE SUSTAINABLE DEVELOPMENT GOALS SUMMARY OF IMPACT 2023 IMPACT BY OPERATION GOVERNANCE OF OUR IMPACT SIBANYE-STILLWATER GROUP IMPACT SUPPLEMENT 2023 14 One of the key objectives of SLPs is to utilise and expand the existing skills base in education for the empowerment of historically disadvantaged South Africans and to serve the community. Please see our various reports available on our SLP programmes, www.sibanyestillwater.com/ sustainability/ community/ Our initiative to promote vocational skills (e.g., plumbing, carpentry, sewing, welding, entrepreneurship, computer skills) has been extended to members of our labour sending communities.

Various centres have been established close to our mining operations to assist our SMMEs, including the assistance in creating Joint Ventures and Partnerships with bigger companies to open opportunities for smaller suppliers, as well as working with bigger companies in creating affiliate business opportunities and introducing SMMEs to possible opportunities within their supply chain. Training: Comprehensive training programmes have been implemented to equip individuals with essential skills for sustainable entrepreneurship. Sibanye-Stillwater’s commitment extends beyond financial support as these initiatives do not cater for a one-size-fits-all approach. The assistance is offered as tailored support based on the needs of the individual SMME’s and can include diagnostics, business acumen training, a start-up pitch programme (that may include grants), boot camps, mentoring, monitoring, physical business support, life coaching, or supply chain integration and funding. In the period between 2021 and 2023 alone, 816 learners participated in the Business Accelerator Programme, enhancing their business acumen and management skills. Additionally, Sibanye-Stillwater provided training in financial management to 38 learners, marketing skills to 39 learners, and project management to 46 learners through specialised accelerator programmes. Recognising the paramount importance of health and safety in the mining industry, 16 learners received training in this critical area. Funding: Through its dedicated funds, namely the CEO Fund and the Supply Chain Fund, Sibanye-Stillwater has catalysed remarkable growth and sustainability. Since inception of these initiatives, these funds have facilitated a substantial R421 million in loans, benefiting 580 companies and creating over 12,000 jobs. Notably, there's a strong emphasis on diversity, with 656 women directors and 657 youth directors supported among the 2,039 total members. Benefiting from our supplier development programme Lekau Group (Pty) Ltd (“Lekau Group”) is a black male-owned business that specialises in, and provides, mining services which include transportation of ore and other materi, plant maintenance, vegetational control, civil works, and road maintenance to a diverse range of clients. Lekau Group’s clientele includes Sibanye-Stillwater, Samancor WCM (Sylvania Metals), Jabula Plant Hire, N4 Bakwena (Bassella), and many others. Intervention: For Lekau Group, carrying various project costs and financing new projects was becoming overwhelming to a point where business cash flow and operational expenditure were affected, ultimately leading to shortage of working capital resources. Recognising the need for assistance, Lekau Group approached Sibanye-Stillwater and, with the assistance of Phakamani, requested funding assistance and expertise in determining the feasibility and profitability of the new projects. Lekau Group were assisted with funding and business skills training and as they grew, they came to understand and practice accounting principles of financial planning, accountability and documentation control, which are crucial in their industry. Outcome: Multiple sessions were conducted with Lekau Group, including an in-depth due diligence analysis, to ensure that Lekau Group is operationally able to finance the loans approved by Phakamani. The process was successfully completed in August 2022 and an initial engagement between Lekau Group, a strategic partner in ore transport and Sibanye-Stillwater finance teams was arranged to validate all elements of the project, which was in ore transportation. The outcome of these initial discussions was positive and led to the approval of funding for the project. An additional vegetation control opportunity arose recently. Lekau Group was able to participate in the tendering process and were awarded the five-year contract. Through the Sibanye-Stillwater Funding programme, which provided working capital, Lekau Group received assistance in purchasing equipment, vehicles, and machinery for the project. 8.2, 9.3 SUMMARY OF SOCIAL IMPACT IN 2023 CONTINUED SOCIAL IMPACT LOCAL PROCUREMENT SPEND (m) OUR GEOGRAPHIC PORTFOLIO OUR PRODUCTS AND MARKETS CHIEF SUSTAINABILITY OFFICER’S MESSAGE CELEBRATING SHARED VALUE SUSTAINABLE DEVELOPMENT GOALS SUMMARY OF IMPACT 2023 IMPACT BY OPERATION GOVERNANCE OF OUR IMPACT SIBANYE-STILLWATER GROUP IMPACT SUPPLEMENT 2023 21 14,529 12,656 16,442 21,415 25,018 103 93 223 212 256 187 SA region: HDP local procurement spend (Rm) US region: Local procurement spend (US$m) AUS region: Local procurement spend (A$m) 2019 2020 2021 2022 2023 LOCAL RETURN ON INVESTMENT Every R1.00 spent on social investment by Sibanye-Stillwater in our SA region footprint, in 2023: • Yields a social return* on this investment of: R15.33 (2022: R8.00) • Generates income per doorstep household** of: R4.58 (given an average household size of 3.34 people) * A Social Return on Investment Study, 2023 ** Institute for Economic Justice (2020).

The project is divided into two streams: (1) digital skills, including technology innovations, and (2) non-digital skills. This will will enable the participants to re-integrate into the economy following closure of the mine through employment after gaining new skills or through entrepreneurship. The project is being implemented with Rand Mutual Assurance (RMA), which provides co-funding and technical support for the rehabilitation and integration of people with disabilities. Implementing partners for this project are Tshimologong Precinct (an entity of Wits University) and Enterprise to the Point (an entity of Growth Point Properties). The project has been initiated, with 50 participants engaging in digital skills programmes and 10 participants in non-digital skills programmes. In addition, 20 digital and 20 non-digital enterprises will participate in the incubation phase. By strategically addressing the imminent closure of the mine, the project hopes to mitigate socioeconomic risks and create a sustainable post-mining environment. By providing foundational skills in both digital and non-digital skills, the project ensures a diverse skill set that caters to a wide range of employment opportunities, promoting inclusivity and diversity within the workforce. ALIEN INVASIVE SPECIES Rand West Alien Trees (RWAT) is a local company owned by four directors who are part of the local West Rand community. The company started as the beneficiary of the Kloof operation’s SLP and, with help from the Group, grew to be a fully-fledged service provider. RWAT is involved in the eradication of alien and invasive species of trees and plants. It employs staff only from neighbouring communities, in line with Sibanye-Stillwater’s goal of developing skills and creating jobs within our community. The company started with just seven employees, with the vision to employ 40 people over the next 24 months. RWAT has partnered with Sibanye-Stillwater and industry specialists such as Agreenco Projects (technical advisors) and Badiri and Associates (project and business advisors) to eradicate invasive alien plants, as part of Sibanye-Stillwater’s goal of protecting and nurturing the environment, as well as restoring and re-introducing indigenous vegetation and trees. The collaboration of all these companies is ensuring that public-private community partnerships (PPCM) will not only benefit the environment but also uplift communities and develop the local economy post-mining. Since the start of the project, 2,397ha of alien vegetation has been eradicated and controlled. This significant milestone has saved an estimated 1,904ML of water in a certain water-scarce area. This is water that would otherwise have been absorbed by the roots of the alien vegetation in the affected area. This water is now released back into the catchment and can provide 26,082 people with water for an entire year (200l/day).

Water treatment In 2023, we offset our municipal potable water demand by 22.32ML per day at the Gold operations and 7ML per day at the PGM operations, by treating impacted mine water to potable water standards and by utilising grey water. This made more potable water available in the Integrated Vaal River System, which serves communities in Mpumalanga, Free State, North West and Gauteng. The combined impact of our interventions is equal to the daily water demand of 123,713 people. Owned: 124,116ha This is equivalent to 14% of the hectares of the Yellowstone National Park, partially located in the state of Montana, US, or the equivalent of 3.2% of the Kruger National Park in South Africa.

The good quality discharge contributes directly to the ecological reserve of the Integrated Vaal river system. We deliver potable water from mine-impacted water at four operations. The Kloof, Driefontein, Ezulwini, and Burnstone potable water treatment facilities have a combined potable water production capacity of 37ML (SANS 241: 2015-compliant drinking water). This means that we indirectly make potable water available daily to 156,000 individuals or almost 31,200 households (consisting of five people). Access to, and the provision of, clean drinkable water for human consumption, sanitation and hygiene purposes is a universal human right and is critical in the SA region. We are currently implementing R&D on water treatment projects (total spend: R3 million). Recovering value from our mining effluent is a key component in changing the long-term business model of water treatment both in an active mine and post-closure. We have shifted our attention to change the risk of mine-impacted water to an opportunity and to investigate value recovery initiatives aimed to extract value from the water bodies, thereby reducing waste and promoting sustainability. The composition of our mine water bodies provides is ideal for nutrient recovery, which can be achieved during desalination and removal of complex monovalent elements. The ecological benefit is that we remove contaminants from the water source; the financial benefit is that these contaminants contain the nutrients essential for fertiliser production. Two key fertiliser ingredients were identified: • Potassium Nitrate • Ammonium Sulphate South Africa is a net-importer of these fertilisers. The current models and results from the pilot studies show that Sibanye-Stillwater can potentially produce 13.9 kt/month if our project is successful. Sibanye-Stillwater entered into a strategic partnership via our IXs innovation programme and is completing the test work. In 2023, in keeping with our circular economy goals, we began producing a simple fertiliser from sodium nitrate waste product. The economic value of this recovery can potentially be set off against costs incurred in our environmental restoration efforts.

In terms of the environment, we are committed to limiting our impact and accelerating our decarbonisation efforts through various renewable projects. Our SA gold operations are largely water-positive, requiring that we pump large volumes of ingress water from deep workings. Our opportunity is to leverage our excess ground water and reduce our dependency on water suppliers. We have various projects to treat our water for reuse purposes.

SA PGM – SUMMARY OF IMPACT 2023 Our three PGM mining operations in South Africa are all located in the Bojanala Platinum District Municipality in the North West Province, specifically within the Rustenburg and Madibeng local municipalities, which have a combined population of 1.2 million people. The mining industry is the largest employer, providing 35% of total employment in the province. The SA PGM operations have a workforce of 47,405. At our SA PGM operations, socioeconomic impact is also delivered through our SLP and CSR programmes, in which strategic partnerships remain key. For example, as part of our economic renewal efforts, the Marikana Agri-Hub managed and operated by the Mineworkers Development Agency is a model agribusiness operation. Limiting the impact on the environment is important for the business, and with the SA PGM operations being located in a water-stressed region, water management is crucial. Water management initiatives in the region include optimising water recovery from tailings storage facilities through scavenger wells and the integration of Marikana with the Kroondal-Rustenburg footprint to balance water requirements across the area.

In 2023, 29% of our SA region’s workforce originates from the Eastern Cape. OUR GEOGRAPHIC PORTFOLIO OUR PRODUCTS AND MARKETS CHIEF SUSTAINABILITY OFFICER’S MESSAGE CELEBRATING SHARED VALUE SUSTAINABLE DEVELOPMENT GOALS SUMMARY OF IMPACT 2023 IMPACT BY OPERATION GOVERNANCE OF OUR IMPACT SIBANYE-STILLWATER GROUP IMPACT SUPPLEMENT 2023 58 Over the years Sibanye-Stillwater has invested in community development projects which include schools and agricultural programmes in the Eastern Cape. The areas in which we are active are the Chris Hani, Alfred Nzo, OR Tambo and Amahlathi district municipalities. The towns on which we focus have a combined population of around 700,000 and include, among others, Engcobo, Lady Frere, Idutywa and Matatiele. Sibanye-Stillwater has optimised its partnership with the National Wool Growers Association by supporting sheep farmers in the Eastern Cape in entering the wool production market. Since 2019, we constructed nine shearing sheds in areas where we used to historically source labour from. This will enable miners to be able to sustain themselves post-employment and their communities to participate in economic activities. The sheds have been constructed in the OR Tambo and Chris Hani District Municipalities. A 2012–2016 backlog project in the Eastern Cape (JS Skenjana senior secondary school in Idutywa) was completed in December 2022, and handed over in April 2023. The construction of the school was funded by Sibanye-Stillwater and R65 million was invested to accommodate 1,600 learners in grades 7 to 9 and to build 33 classrooms, science and computer laboratories, media and nutrition centres and a recycling area at the school. As distinct from our legislated SLP commitments, we also benefit communities through CSI (also referred to as CSR). In 2023, our CSI focus areas were: welfare of vulnerable people (women, children, and persons living with disabilities); education; youth development; health; sports; and food security. In 2023, we have built school ablution facilities in seven schools in the Eastern Cape, as part of the Presidential Sanitation Appropriate for Education (SAFE) programme. Sibanye-Stillwater continues to provide for employees who become paralysed as a result of work-related injuries, by renovating/adapting their homes for their needs. Injured employees want to return to where they originally came from and our home upgrades extend to labour sending areas. These projects include building and renovating homes, as well as widening doorways, ramps and pathways to help beneficiaries move around their homes with ease.

In 2023 the spend on community giving were: • US$0.19 million on community projects • US$0.11 million on education • US$0.06 million on emergency and rural healthcare services • US$0.04 million on environmental stewardship In May 2017, Sibanye-Stillwater embarked on a transformative journey with the acquisition of the US-based Stillwater Mining Company, marking a significant milestone in the company's history. This acquisition facilitated geographic diversification into the Americas and ushered in a new era of sustainability and responsibility. With a focus on autocatalyst recycling, Sibanye-Stillwater is pioneering a circular economy model that not only meets the demands of today but also ensures a sustainable future for generations to come. Autocatalyst recycling has emerged as a cornerstone in the global supply chain of platinum group metals (PGMs), including platinum, palladium, and rhodium. This process helps offset the demand for these critical metals by extracting and reusing them from end-of-life vehicles and other sources. With advancements in recycling technology, the industry has witnessed efficient recovery of PGMs, contributing significantly to the overall supply. Recycling plays a crucial role in reducing the pressure on primary mining operations, thereby fostering a more sustainable source of these metals. Compared to traditional primary PGM ounces, the recycling segment emits significantly less CO2, uses minimal water, and generates substantially less waste. In fact, the production of the same amount of metal through recycling emits 6 times less CO2, uses 63 times less water, and generates 90 times less rock waste compared to our US PGM mining operations, underscoring the environmental superiority of recycling.

These autocatalytic converters, housing precious metal catalysts, are pivotal in curbing detrimental pollutants like carbon monoxide, hydrocarbons, and nitrogen oxides. By adhering to stringent emissions standards and regulations, autocatalytic converters facilitate vehicle compliance with environmental mandates, thereby promoting the development of cleaner automotive technologies and catalyzing innovation in air emissions control systems. Autocatalytic converters contribute to mitigating several environmental and climate-related issues by reducing harmful emissions from vehicles. By targeting pollutants like carbon monoxide, hydrocarbons, and nitrogen oxides, these converters indirectly affect greenhouse gas emissions, thereby aiding in the global effort to combat climate change, a philosophy aligned with the Sibanye-Stillwater purpose to Safeguard global sustainability through our metals. Additionally, by improving local air quality and reducing the emission of harmful pollutants, autocatalytic converters create healthier and more sustainable urban environments. Our commitment to autocatalyst recycling exemplifies the Group’s dedication to sustainability, innovation, and responsibility. Through its leadership in the recycling industry, the Group not only meets the demands of the present but also ensures a brighter and greener future for generations to come. As the world transitions towards a circular economy, we remain at the forefront, driving positive change and making a lasting impact on the environment and society.

We recognise that climate change: • Is a serious global challenge with significant disruptive impacts to the environment, to society and to business • Could seriously impact weather patterns (droughts, floods, storms, etc.), putting our facilities at risk (including tailings storage facilities and water infrastructure), potentially exacerbating water scarcity in water-stressed areas where we operate e.g., our SA PGM operations • Demands an urgent response from a multitude of stakeholders including business, governments and civil society • Is accelerated by anthropogenic (human) activity and its resultant greenhouse gas emissions, and calls for taking responsibility for the environmental and societal impacts of our actions Sibanye-Stillwater’s position on climate change is that: • We support the Paris Agreement, which is to limit global warming to below 2 degrees Celsius, but preferably to 1.5ºC, compared to pre-industrial levels • We must contribute to the solution by reducing GHG emissions in our mining operations and engaging with market-based approaches that encourage low-emission technologies and that would contribute towards a global low-carbon economy • Publicly disclosing the Group’s approach to climate change • Aligning to the recommendations and guiding principles on climate-related disclosures from the Task Force on Climate- related Financial Disclosures (TCFD), SEC, etc., is the first step towards achieving broader Sustainability risk based disclosures • Given the direct relationship between climate change and energy demand, our emissions abatement should focus on demand side energy management, sourcing of clean, reliable, affordable energy and low-carbon technology adoption that enables decarbonisation • For Sibanye-Stillwater to create value for stakeholders (including investors) we should focus on climate-change resilience, mitigation and adaptation with an emphasis on enabling a just transition through finding economic opportunities within the low carbon economies GROUP SUPPLEMENTARY INFORMATION 2023 1 We support the global response to climate change in two primary ways: by delivering commodities needed for the global mitigation and reduction of carbon emissions, and by reducing our own carbon footprint. Our approach and intent in respect of climate change is expressed in one of the four sustainability themes that support our sustainability strategy, namely: Develop a climate change-resilient business. Climate change has been identified as a material issue, in terms of both physical climate risk and transition climate risk. Our climate change response is underpinned by reducing greenhouse gas (GHG) emissions from our operations and activities and building organisational resilience to the impacts of climate change, as the world transitions to a low-carbon future. This is in line with the goals of the Paris Agreement 2015, (a legally-binding international treaty on climate change) and other international protocols. We are committed to playing a leading role in mitigating climate change and to be carbon neutral by 2040. Our commitment is supportive of the International Council on Mining and Metals (ICMM) Climate Change Position Statement (2021) goal of achieving net zero by 2050, or sooner. In addition, we also consider the JSE Sustainability and Climate Disclosure Guidance and we are a member of the Industrial Task Team on Climate Change (ITTCC), through the Energy Intensive User Group of Southern Africa. CLIMATE CHANGE SUPPLEMENT Building a climate change resilient business SIBANYE-STILLWATER’S APPROACH TO CLIMATE CHANGE CONTENTS Sibanye-Stillwater’s approach to climate change 1 Our journey 3 Governance 4 Strategy 6 Risk management 8 Metric and targets 15 TCFD Gap analysis and Peer review In 2023, Sibanye-Stillwater engaged an independent service provider to conduct a gap analysis and peer review , as part of a broader TCFD study, to compare Sibanye-Stillwater’s TCFD maturity against five of our mining peers, using publicly available documents for comparative purposes. Broadly, the results indicate that in terms of two of the four TCFD disclosure requirements, namely “governance” and “metrics and targets”, Sibanye-Stillwater is industry-leading and high on the maturity scale. However in the “risk management” and “strategy” disclosure categories, Sibanye-Stillwater was found to be mid-way on the TCFD maturity scale. The work that started in late 2022 and was completed in Q4 2023, focused on addressing the gaps identified whilst deepening the TCFD-related work already done. As part of the TCFD scope of work, climate change scenario analyses (on physical and transitional climate risks) were completed for all operations in 2023. In 2024, we will focus on refining the outcomes of the first phase, actioning and operationalising all findings and recommendations from the TCFD study and respective reports and, where relevant, to further investigating specific climate risks and opportunities identified in specific operations or regions. As articulated in our Energy and decarbonisation position statement (www.sibanyestillwater.com/ sustainability/reports-policies), our operations are energy-intensive and use both direct (coal, diesel, etc.) and indirect (electricity) energy sources. Energy also forms a significant and growing component of our operating cost structures. In 2023, 78.6% of the Group’s emissions stemmed from electricity consumption (scope 2), almost exclusively (97.2%) attributable to South Africa’s power utility, Eskom, which generates the vast majority of its electricity from coal. Scope 1 emissions comprise 6.3% of Group emissions, while indirect emissions related to scope 3 contributed 14.5% of our Group emissions. It is imperative that we manage energy as a strategic input, both in terms of supply and demand. Effective energy management and decarbonisation will become a competitive advantage and enhance our ability to deliver on our strategic differentiators. As a responsible operator, Sibanye-Stillwater will continue to contribute to the mitigation of global warming by focussing on renewable energy and by mining green metals that support the transition to renewable energy. The business strategy uses the term ‘grey- elephants’ to describe highly probable, high impact, yet neglected catalysts of change set to shape the future. In particular ‘angry planet’ is one of the grey elephants considered. An increasing incidence of extreme weather events has been experienced in many parts of the world with systematic changes in local climates. As the planet heats up, natural disasters are becoming more frequent and severe. In our three-dimensional strategy, we address climate change in terms of one of our strategic differentiators. (See Integrated report 2023, page 48). GROUP SUPPLEMENTARY INFORMATION 2023 2 Sibanye-Stillwater ranks highly in the governance theme. Sibanye-Stillwater has been marked down for its 2022 performance for not having completed detailed quantitative physical and transition scenario modelling which has now been completed. Sibanye-Stillwater has adequate external risk management reporting. Risk management reporting could be improved with further discussion of physical and transition risks. Sibanye-Stillwater reports well on its metrics and targets, putting it high on the ranking against its industry peers.

The Social, Ethics and Sustainability Committee and the Risk Committee (both Board committees) have a role in advising on our climate change response, providing strategic direction and overseeing the implementation of our strategy in this respect. The Social, Ethics and Sustainability Committee helps to guide the Board in respect of the Group’s sustainability priorities (including climate-related matters), ethics, and corporate citizenship. The terms of reference of the Social, Ethics and Sustainability Committee include the formulation of the Group’s climate change response as part of the duties of this committee. The Sustainability strategy, overseen by this committee, has a thematic approach towards sustainability and ESG, which is inclusive of climate change priorities. The committee’s annual work plan for 2023 included in-depth discussion on climate-related disclosures. During 2023, Board members received training on climate disclosure practices. Board members’ biographies are available at www.sibanyestillwater.com/about-us/leadership for further detail on individual climate related experience. Eight out of eleven independent non-executive directors have climate change and sustainability expertise. Reporting to the Board on climate-related issues takes place quarterly from the CEO and the Chief Sustainability Officer (CSO), supported by relevant Vice President for ESG. The CEO provides leadership on policy and strategic direction, and provides the Board with comprehensive information, analysis and advice on all aspects of the business, which includes climate-related issues, risks and opportunities. The Risk Committee oversees risk management (including processes and controls). During 2023, the Risk Committee reviewed the Group strategic risk register, which includes extensive detail on impacts relating to climate change. Climate-related issues and impacts are part of their risk/opportunity identification processes. We are aware of climate change impacts on our operating sites, and the possibility of these becoming more severe. The Investment Committee, a Board committee, has the final decision-making power on investments; this is inclusive of building a portfolio of green metals and on decarbonisation projects linked to renewables. For example, Sibanye-Stillwater is actively pursuing strategic opportunities in mining metals that aid in the global transition to a low-carbon economy. On 28 November 2022, the Board approved the capital expenditure for our Keliber lithium project, beginning with the construction of the Keliber lithium hydroxide refinery. The selected technology solution is provided by global leaders Metso Outotec and FLSmidth. Our Keliber lithium hydroxide production is based on soda leaching technology, which is expected to be more energy efficient, with a lower environmental impact than alternative processes. Board involvement on climate risk In 2023, through the Social, Ethics and Sustainability Committee, the Board commissioned an extensive assessment of Group climate risks (both transition and physical), which was aligned with the TCFD climate-related disclosure requirements. The assessment completed by an independent London-based risk-management consultancy firm was presented to the Board and highlighted the latest thinking on climate risks and climate resilience. It gave the members of the Board an opportunity to deep-dive into the issues at hand. Board members have studied the report and taken the opportunity to broaden and deepen their knowledge around climate change. C-suite and executive The Chief Technical and Innovation Officer (CTIO), who reports to the CEO, has an oversight role and guides decisions on technical issues, including our energy and decarbonisation strategy. The CTIO supports the CEO in key decisions by ensuring that strategic climate-related objectives translate into operational targets and initiatives.

The Vice President (VP): Energy and Decarbonisation, reporting to the CTIO, ensures the effective implementation of our Energy and decarbonisation strategy with the goal to achieve carbon neutrality by 2040. The CSO oversees sustainability within the Group, including strategy on climate-related issues. The Senior Vice President (SVP): Sustainability and ESG as well as the VP: Environment and Climate change report into the CSO. The CSO informs the C-suite on strategic issues relating to climate change. The CSO reports quarterly to the Social, Ethics and Sustainability Committee, including providing updates on the Group’s progress in meeting climate change-related targets. An ESG scorecard is linked to long-term incentives for executive remuneration. An internal ESG committee reviews and reflects quarterly on sustainability performance, inclusive of climate-related matters. Training, awareness and competence forms an integral part of embedding ESG generally, (including climate) for key leadership. Operational Management, budgeting and operational compliance reside with the respective Chief Regional Officers (CROs) and operational Executive Vice Presidents (EVPs) in the respective regions. The EVPs and their respective senior management teams are accountable for all climate change initiatives and the costs thereof at their operations. The operational EVPs are supported by relevant operational SVPs (e.g., SVP: Technical services, with the SA region EVP: Technical services) and VPs (e.g., VP: Engineering), who execute the initiatives to manage and reduce the effects of climate change management and the implementation of associated initiatives. TCFD alignment project TCFD was the primary global regulatory instrument for climate reporting and disclosures other climate reporting and disclosures frameworks such as that of the SEC and International Sustainability Standards Board (ISSB) are now coming to the fore] and Sibanye- Stillwater conducted a climate risk analysis as per the TCFD framework. In this first phase of the project a gap analysis and peer review benchmark were undertaken and these outcomes further informed the scope of the TCFD climate risk analysis. This phase consisted of physical and transition risk scenario analysis. Project oversight and governance for the TCFD project was provided by an integrated TCFD Steering Committee (steercom), that included C-suite members and regional functional owners. This steercom was responsible for guiding and approving the scope of the study, as well as signing off the final TCFD reports, ensuring the results inform Group-level risk and reporting, and that the alignment project fits with the Group’s broader business goals. The TCFD alignment project (which started with a climate scenario analysis in 2019, followed up with a TCFD aligned diagnostic study in 2021) was also supported by regional and operational project teams, including a GIS team that provided spatial data maps of the Group’s assets, and a risk, finance and insurance team to provide related financial and insurance data. Twenty-one of our operating units across the Group, were included in the scope of the project. These include, inter alia, some of the investments and operations such as Mimosa, Rand Refinery and Sandouville, but excluded projects currently under construction such as the Keliber lithium project. Climate related remuneration Annual long-term incentive (LTI) awards are awarded to VP level and above. Following a review during 2020, the Remuneration Committee introduced a third performance condition from the 2021 cycle that includes ESG factors, weighted at 20% of the LTI awards. An ESG scorecard was developed by grouping factors into four sustainability themes under which 12 indicators reflect our priorities. The ESG scorecard has further evolved in 2023 with one of the strategic thrusts for the 2023 scorecard “developing a climate change resilient business”, with associated indicators relating to a reduction of GHG emissions, reduction of water use, increase in water quality and assessment of tailings risks. The GHG emissions targets are aimed at limiting annual scope 1 and 2 emissions in line with our near- and long-term emissions reduction targets. The next cycle of the ESG scorecard commences in 2024, and the new metrics are under review to guide the next cycle of maturity. See the Integrated report, page 264. Responsible principles We are members of the ICMM, World Gold Council (WGC), and the International Platinum Association (IPA), which all have membership requirements related to climate change. We participate in the United Nations Global Compact (UNGC) and have a supplementary report detailing our alignment and performance against the Sustainable Development Goals (available www.sibanyestillwater.com/news-investors/reports/ annual/). Our operations, excluding the Keliber lithium project and Australia region, are ISO 14001 certified, setting the environmental management system requirements. SEC disclosure requirements In March 2022, the Securities and Exchange Commission (SEC) proposed climate disclosure requirements to apply to periodic reports beginning in the 2023 annual report but various delays were experienced and the final requirements were published in early March 2024. The final version excludes Scope 3 reporting requirements. Beneficial to Sibanye-Stillwater is the Group’s current alignment to TCFD and other disclosure regimes which will largely assist in meeting the SEC disclosure requirements. JSE climate guidance Sibanye-Stillwater aligns to the JSE’s climate guidance. The JSE requires an organisation disclose its performance metrics and targets to measure, monitor, and manage its sustainability impacts, risks and opportunities. It should also disclose its performance against these metrics and targets. IFRS Sustainability (S1) and Climate related standards (S2) The ISSB recently published the IFRS (international financial reporting standards) sustainability standards (IFRS S1 and IFRS S2), which build on the TCFD recommendations. TCFD was incorporated into these standards, with IFRS S2 having some additional requirements to disclose. Sibanye-Stillwater has, through the services of PwC, commissioned an initial assessment for alignment purposes with the IFRS sustainability standards and is continuing to investigate these standards’ reporting implications. GROUP SUPPLEMENTARY INFORMATION 2023 5 Assurance Independent auditors, KPMG, perform limited assurance on the total GHG emissions excluding Australia (scope 1, 2 and 3) as well as electricity consumed and total water withdrawn. The assurance opinion is available on page 285 of the Integrated report. KPMG has also assured conformance to ICMM and WGC principles of which both these organisations consider climate change impacts. The Rustenburg and US operations have commenced with IRMA audits. IRMA is site specific and does cover GHG emissions as one of its chapters. We conformed with the conditions of the Global Industry Standard on Tailings Management (GISTM) which is inclusive of community based emergency aspects. Areas to improve governance around climate change Following consultancy from third parties, including the improvement recommendations from the TCFD gap analysis, the Group is considering the following actions to improve its governance on climate change risk: • Specific measures for Board’s performance against climate- related responsibilities • Enhance oversight of climate-related risks by management and establish thresholds for escalation of climate risk issues to Board • Document the process for considering climate related risks and opportunities in financial planning and strategic decision- making along with a diagram of related roles and responsibilities • Map the climate-related roles and responsibilities across the organisational structure to provide more clarity on the flow of reporting up to Board, and coordination of the different roles STRATEGY One of our four strategic differentiators is to build a Unique global portfolio of green metals and energy solutions that reverse climate change. The risk of climate change is embedded in our strategy and is an opportunity to be part of the world’s solution to carbon- free energy and mobility, by investing in battery metals and other metals that are key to the green transition and reducing our operational GHG emissions in line with the goals of the Paris Agreement 2015. Complementary to our green metals strategy, we also implementing our Group energy and decarbonisation strategy which aims to deliver operational (scope 1 and 2) carbon neutrality by 2040 and, in turn, low carbon commodities for our customers. Further we are increasing our investment in recycling of metals and minerals that advance circularity. (See Integrated report, page 36 external environment for our business and operations.) Our climate change position statement (www.sibanyestillwater.com/sustainability/reports-policies/) sets out our approach to climate change. As articulated in this policy and other strategic documents we are committed to the following: • Execute our energy and decarbonisation strategy to achieve carbon neutrality by 2040 • Achieve net zero status by 2050 • Track our GHG emissions (absolute emissions) against targets approved by the SBTi (Science-Based Targets initiative) • Build operational resilience to the effects of climate change and support stakeholders affected by climate change, including host communities • Implement recommendations of the TCFD and address risks and opportunities presented by climate change • Influence climate-related policy and decision-making through advocacy and participation in forums and stakeholder platforms • Encourage supply chain partners to adopt climate-resilient, and emissions reductions, approaches GROUP SUPPLEMENTARY INFORMATION 2023 6 Our aspiration to be a climate change-resilient business directs our attention towards climate resilient opportunities. As a large electricity consumer, energy management is the most fundamental way in which we can contribute to mitigating climate change, whilst addressing electricity constraints in the SA region. Our commitment to carbon neutrality by 2040 is underpinned by our energy and decarbonisation strategy. Energy and decarbonisation strategy Strategic Energy sourcing Sourcing energy from low-emissions sources is our strongest lever and opportunity for reducing our GHG emissions footprint, particularly for the SA region given that Eskom is responsible for approximately 90% of Group scope 1 and 2 emissions. The SA region has developed a 632MW pipeline of solar and wind projects which will displace 30% of current Eskom supply with low-cost, renewable energy by 2027. We have successfully advanced 267MW of generation capacity (one solar and two wind projects) into construction. Sibanye-Stillwater will be atop three private power procurers in South Africa on completion of its renewables programme. The projects being developed (267MW) will reach commercial operation by end-2025 and reduced emissions by c.920,000tCO2e per year (15% of Group scope 2 emissions). The balance of projects are planned to reach financial close in 2024 and commercial operation by end-2026. The projects are expected to deliver electricity at a 20–30% discount to forecast Eskom tariffs, escalating at CPI. The projects further assist in mitigating indirect future carbon tax liabilities associated with the use of fossil fuel-based electricity. The projects each comply with the requirements of the Mining Charter and enable socioeconomic development through bespoke programmes based on local needs. Our EU region assets (Keliber and Sandouville) are strategically located in countries with low grid emission factors, where electricity supplied by local networks have a high penetration of renewable energy or low-carbon generation sources. Despite this inherent benefit, we continue to investigate opportunities to source 100% renewable supply. For the US region, we are investigating opportunities to procure lower-carbon electricity and dedicated renewable energy projects for the operations. The Columbus Metallurgical Plant already operates a small solar photovoltaic plant to supplement a portion of their electricity requirements. For our AUS region, the CopperString 2032 project involves 840km of new electricity transmission line from just south of Townsville to Mount Isa to connect Queensland’s North West Minerals Province to the National Electricity Market. Approximately 200km of additional transmission line will be required to connect new renewable generators to CopperString. The construction of the project will provide the Century operation with enhanced opportunities to access renewable energy supply. GROUP SUPPLEMENTARY INFORMATION 2023 7 STRATEGIC OBJECTIVES • Reduce absolute GHG emissions • Ensure security of energy supply • Enhance sustainability through reduced energy and carbon costs • Partnering to enable value-chain decarbonisation and a just energy transition Decarbonisation advocacy and just transition Creating an enabling external and internal environment for decarbonisation Demand side energy management • Eliminating energy waste and enhancing operational efficiency • Minimising load curtailment impact Technology adoption Leveraging technology, including digital, storage and hydrogen Strategic energy sourcing Sourcing low-cost, reliable renewable energy Scope 3 emission reduction Addressing our up and downstream emissions as part of our broader value chain Carbon offsets Responsible use of carbon offsets to neutralise our remnant hard-to-abate emissions Just transition The transition to a low-carbon economy has to be just, fair and equitable. Our journey towards climate resilience therefore needs to be cognisant of this just transition, as well as of the direct and indirect impacts of climate change and our climate resilience programmes and initiatives on our employees, our communities and on other key stakeholders. In partnership with the Mineworkers Development Agency, a non- profit organisation dedicated to helping workers establish livelihoods post mining, the Marikana Hub has been operational for two years. It is supported by the Presidential Employment Stimulus programme. Through the programme, the Hub teaches people about being climate smart and about regenerative farming techniques. In October 2023, the inaugural Sustainability Thought Leadership Dialogue series took place. The first dialogue – titled ‘Facilitating a just transition to post-mining economy’ – attracted excellent engagement, with 300 participants joining on the virtual platform. The key speakers were Mr Moustapha Kamal Gueye (Director of the Priority Action Programme of the International Labour Organisation) and Ms Lebogang Mulaisi (COO of the Presidential Climate Commission). The overall objective of the dialogue was to promote a culture of engaging in complex sustainability conversations and to share sustainability and climate change related information that is relatable in everyday work. Emergency preparedness For the SA region we have an agreement with Gift of the Givers Foundation (a disaster response NGO) to provide support should unwanted events (e.g., flooding) occur at our operations. Gift of the Givers Foundation is the largest disaster response non- government organisation in Africa. A new weather station at the Stillwater mine, US PGM operations improves our ability to monitor climate conditions around the site. It is located west of the Stillwater mine’s tailings facility and has been equipped with instruments to measure various weather conditions and data to help better protect employees and operations through enhanced weather, and ultimately, climate predictive capabilities. RISK MANAGEMENT One of the four TCFD thematic pillars is Risk management, which comprises the disclosure on how companies identify, assess and, manage climate-related risks and opportunities, and how all of these processes are incorporated into existing company-wide risk management frameworks. Our recent TCFD work included a comprehensive scenario risk analysis (modelling), taking into consideration different climate- related scenarios and by modelling physical and transition risks that may influence the strategies of our business. Further, as an integral part of governance and under custodianship of the Group Risk department, a comprehensive enterprise-wide risk management process is used to assess and rank climate change related risks in the Group. Physical climate risk modelling Our model for assessment of physical risk, followed a certain design scope, approved by the TCFD steercom. We modelled two climate scenarios: the Intergovernmental Panel on Climate Change’s (IPCC) Representative Concentration Pathway (RCP) 8.5 [~4°C warming] and RCP 2.6. [~1.5°C warming]. Sibanye- Stillwater is of the opinion that warming will most likely be in the range of 2°C–4°C and is planning accordingly. We used RisilienceTM software that uses the latest climate models, as our climate model vendor. (The RisilienceTM model combines data and insight from research undertaken by Cambridge university centre for risk studies, aligned to TCFD and global best practice, and recognised by leading international authorities, including the United Nations.) We also modelled for seven climate perils that represent the most critical and material risks across our global operations: coastal flood, freeze, riverine flood, temperate windstorm, tropical windstorm, drought/water stress, heatwave. This risk modelling approach does not include the indirect-climate related perils for example, surface water, forest fire (a possible consequence of drought, which is a climate peril), and soil subsidence. These are, however, largely mitigated through operational risk management strategies at site level. The time horizons for the model consist of seven time steps: 2020, 2023, 2025, 2027, 2032, 2040, and 2050. We consider the first for of these steps to be short-term (within five years), 2032 is considered medium term (5–10 years), and 2040 and 2050 are long term (over 10 years). The model covered 21 operations in the different jurisdictions where we operate including the Century operations in Australia. The spatial resolution was mapped to as low as one square kilometre, and varied between the seven perils. DESCRIPTION OF THE SEVEN PERILS MODELLED GROUP SUPPLEMENTARY INFORMATION 2023 8 Coastal flood: Rising sea levels and higher incidence of extreme coastal flood events, factoring in daily maximum and wet bulb temperature exceedance. Freeze: Changes in the annual freeze and thaw cycles resulting from winter periods that trend close to freezing point, factoring in daily minimum temperature exceedance. Riverine flood: Increased frequency and intensity of rainfall changing the frequency and intensity of river flooding, accounting for aqueducts and other water channels. Temperate windstorm: Contrasts in air temperatures that have the potential to enhance wind speeds, factoring in daily maximum and wet bulb temperature exceedance. Tropical windstorm: Changes in sea surface temperatures that have the potential to enhance wind speeds, factoring in daily maximum and wet bulb temperature exceedance. Drought/water stress: Reduction in the availability of water for industrial use over a wide wide-spread area, accounting for rainfall deficit exceedance over variable durations. Heatwave: New extremes of high temperatures, more frequent hot days and longer longer-lasting heatwaves, factoring in daily maximum and wet bulb temperature exceedances.

Value chain asset inclusions Our model factors in the vulnerability of all our assets, as well as that of certain critical assets owned and operated by third parties but that contribute towards the operability of our mines and the movement of of raw materials from supply chains and finished product to the market, e.g. substations, access roads, railway lines, etc. Assets were divided into six “vulnerability archetypes.” For each asset we considered risk in terms of both property damage and business disruption (resulting in revenue loss). The six vulnerability archetypes are: SEI (surface energy infrastructure) SPTR (shafts, plants, tailings, and refineries) MSI (mine surface infrastructure) RPC (residential property/community) MB (miscellaneous buildings) TIU (transport infrastructure and utilities) Physical model assumptions and limitations We made certain assumptions and limitations for the modelling of physical risk. These include, but are not limited to, the following: For modelling purposes, ‘value of assets’ remains constant across timeframes (not affected by inflation, depreciation, appreciation, or any regulatory, political, market or fiscal impacts) Latest (2023) GIS data was used for modelling New or planned assets, or extension to current life of mine were not considered Reinstatement values are from 2023–2024 insurance declarations or latest available evaluations Exchange rates are FOREX closing rates for July 2023, and are fixed in the future In terms of our modelling, physical climate risks would manifest in one of two ways: (1) property damage (defined as the impact of damage caused by climate change risks to owned assets); and (2) business interruption (defined as the impact of downtime and disruptions, caused by physical climate risks to operations). Property damage The output of our model for property damage is financial quantification of the possible expected average annual loss (AAL) caused to Sibanye-Stillwater owned assets. This would be due to possible physical climate risks based on estimated asset reinstatement values [reinstatement value = the total amount it would costs to completely rebuild an asset, as per our risk and insurance schedules ]. Financial impact due to property damage to owned assets increases slightly over time in the 4°C warming scenario (RCP8.5), and decreases slightly over time in the 1.5°C warming scenario (RCP2.6). Considering both climate warming scenarios (1.5°C and 4°C), our model in terms of property damage shows little change over time, with decreased exposure to riverine flooding and freeze balancing increased exposure to windstorm and coastal flooding. 1.5°C warming (RCP2.6) 2020 2023 2025 2027 2032 2040 2050 4°C warming (RCP2.6) Drought/Water stress* Heatwave* Coastal flood Tropical windstorm Temperate windstorm Freeze Riverine flood 2020 2023 2025 2027 2032 2040 2050 Note: All outputs are generated as on an average annual basis in line with modelling best practice for TCFD. Drought and heatwave are not considered within property damage metrics as they do not cause “direct” damage. Their impacts are factored within business interruption due to their ability to cause indirect impacts to assets and value chain. The risk potentially causing the highest property damage for the Group is riverine flooding, followed by freeze and temperate windstorm. GROUP SUPPLEMENTARY INFORMATION 2023 9 Business interruption: long term outlook Our modelled outcomes for business interruption assess the expected disruption due to physical climate risk, measured in average number of days of disruption annually. Assets included comprise the full Sibanye-Stillwater value chain. Both climate warming scenarios show a significant change in the number of days of disruption over time, with increased exposure to drought and heatwave. Average number of days disruption across all assets increases significantly over time, roughly doubling in both climate scenarios. Drought and heatwave impacts increase over time and are the cause of the increase in overall disruption. Note: these business interruption results are aggregate annual averages across the portfolio – asset level data is accessible in our physical modelling dashboard, and is available to members of the public on request. Hotspots The report identified “high risk hotspots” at an operation/entity level, considering property damage/ business interruption for 2050 under a 4°C warming scenario. Temperate windstorm represents the major intensifying peril in Sibanye-Stillwater’s asset portfolio, increasing markedly over time.

However, it also highlighted what still needs to be done. The report provides extensive detail on how we close the TCFD gap; what follows is a general overview of the gap-closing areas in progress: • Include investor-ready summary of the climate modelling results (and any subsequent survey/ adaptation activities) within mandatory and voluntary reporting CDP/TCFD disclosures and ESG reporting • Implement a training programme (including C-suite and regional/site managers) to ensure all relevant business functions are aware of the implication of physical climate risk and how it should be managed • Embed results into existing ERM procedures • Use outputs to influence long-term planning and strategy The following are recommended next steps that involve starting from a clean slate: • Map dependencies within each operation, including transport, power, raw materials, workers and other sites (this will allow more accurate quantification of business interruption exposure at site- and operation-level) • Peril-focused analysis for “hotspot sites” which have significant risk • Undertake asset-level surveys for operations to increase understanding of how operations and individual assets will be affected by climate-related events • Regularly rerun climate modelling to reflect latest climate risk data and incorporate modelling updates • Update modelling to include life of mine analysis to inform changing financial exposure over time • Identify appropriate mitigation actions to protect against key exposures, by using inter alia, recognised climate resilience planning toolkits • Roll out mitigation plans across at at-risk operations and monitor regularly to ensure they are fit fit- for-purpose In short, the main gap to fill in terms of physical risk, is risk mitigation at the operations. Our key focus will be on working with operations to ensure that they have measures of resilience and mitigation in place, as per the requirements of the TCFD. Transitional risk Transition risk modelling entails the assessment and quantification of the business impacts associated with the global transition to a lower carbon-intensive economy. Modelling for climate transition risks is a complex task; relying on various assumptions about how the future will play out, and how governments will regulate emissions, and how society will respond. In terms of methodology: 1. We built a digital twin (virtual representation of Sibanye-Stillwater’s business model) for which we analysed and quantified transition risks. 2. We mapped each transition module to the Group’s business value chain and assessed how they will materialise. The transition modules are: liability, investors, technology, carbon policy, quantity demanded, pricing impacts. 3. We applied five decarbonisation pathway scenarios (“external transition drivers”) and associated climate change outcomes. The scenarios are: no policy (>4°C), current policy (3°C), stated policy (2.5°C), Paris limit (2°C), Paris aspiration (1.5°C). This modelling exercise will enable the Group to improve compliance with TCFD reporting requirements and will complement our already existing in-house work on transition risks. In terms of the business impacts on the six transition risks, these are divided between four cost-related risks and two commodity related risks/opportunities. GROUP SUPPLEMENTARY INFORMATION 2023 11 Cost-related transition risks The cost-related transition risks are: • Liability (plaintiffs litigating the Group for harm caused by emissions) • Market investor (impact to cost of capital should investors favour less carbon intensive sectors/organisations) • Technology (depreciation of assets, and need to invest in new assets, in response to new requirements for low-emissions technology) • Carbon policy (government legislation that imposes costs, e.g., carbon tax, on emissions) Risks for these four are summarised in the infographic alongside: ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– For market investors, this infographic only quantifies borrowing costs and not cost of equity. Climate transition is expected to impact lender appetite and investor confidence, affecting companies’ cost of capital (including cost of borrowing and cost of equity). Weighted average cost of capital (WACC) is therefore affected by the world’s response to climate change (e.g., no policy versus Paris aspiration responses) and by the Group’s response in terms of compliance and how it deals with market perception. Higher/lower WACC values will impact the present value of the cash flows a company generates and, ultimately, a company’s value. The magnitude of the measures taken to limit climate change will impact both lender and investor aims and overall confidence, causing changes in the cost of equity and debt and therefore a company’s WACC. Sibanye-Stillwater’s share price and cost of equity is expected to benefit from the higher levels of confidence associated with the world moving closer to Paris Aspiration scenarios if Sibanye-Stillwater’s share price moves in accordance with its theoretical value. GROUP SUPPLEMENTARY INFORMATION 2023 12 No Policy (>4°C) -41 Stated Policy (2.5°C) Paris Agreement (2°C) Findings Recommendations Liability • Liability is a non-priority risk for Sibanye-Stillwater • This only becomes significant under a No Policy scenario • In the long term, study opportunities to accelerate decarbonisation strategy to mitigate exposure Market Investor1 • Sibanye-Stillwater, as a member of a high emitting industry, is expected to experience higher borrowing costs • This additional cost will be more substantial if the economy accelerates its decarbonisation efforts • Communicate to the market Sibanye-Stillwater’s decarbonisation plan, as well as the pivotal role of mining in the global transition Technology • Sibanye-Stillwater’s additional investment costs due to its asset fuel utilisation are non-material due to the partial electrification of its machinery, and high outsourcing and depreciation of its vehicles • Accelerate programs to electrify vehicle fleet or further outsource fleet to limit risk retention • Consider creating a longer- term strategy for introduction of non-fuel powered assets Carbon Policy • Costs due to carbon emissions will be Sibanye-Stillwater’s most significant transition cost • Its planned decarbonisation strategy will partially mitigate the magnitude of this cost • Escalate electrification of assets to reduce carbon costs resulting from scope 1 emissions • Explore alternatives to Eskom (e.g., renewables) Note: 1. Only the impact on Sibanye-Stillwater’s borrowing costs have been quantified (impacts on the cost of equity have been qualitatively analysed and will be subsequently addressed in the Market Investor section of this report). COST-RELATED RISKS SEGMENTED BY CLIMATE TRANSITION SCENARIOS; PRESENT VALUE IMPACT OVER THE NEXT FIVE YEARS – ZA Rm

Carbon policy As displayed in the infographic, the biggest transitional risk is the Carbon policy, which is forecast to impact free cash flow the most (between 2% and 4% negative impact. Our Carbon policy is the Group’s most significant transition cost, partially mitigated by our plans for decarbonisation. Our carbon costs will be driven by scope 2 emissions, exacerbated by our reliance in South Africa on Eskom. Carbon pricing instruments include carbon tax (which is a factor for the Europe region and the SA region), and emissions trading systems (ETS), where emitters trade emission units on a market to meet emission targets based on an industry cap. An ETS establishes a market price for GHG emissions, which can be a significant expense for carbon-intensive companies. The UK, China, Canada, and multiple US states also have ETSs in place. The EU has the largest ETS, covering 40% of its emissions. The carbon border adjustment mechanism (CBAM) is another potential carbon cost, although it does not currently affect Sibanye-Stillwater as the Group does not import CBAM specified carbon intensive goods into the EU; and the expansion of CBAM scope in the near-future is not yet defined. In terms of carbon pricing, these are growing across the world and according to the World Bank, now cover 11.66GtCO2e, representing 23% of global GHG emissions. Meanwhile, in 2023 EU carbon tax hit an all time high of over €100 per tonne of CO2. If the world is to meet the Paris Agreement global emissions target, then carbon pricing would need to reach US$75 per tonne, from today’s global average of US$3 per tonne. Thus, there is the potential risk for a precipitous increase in carbon pricing. As the infographic alongside shows, South Africa has disclosed their carbon tax till 2030, which provides certainty in the short to medium term. The carbon tax rate will increase from R159 per tonne of CO2 in 2023, potentially up to R463 per tonne of CO2 in 2030. South Africa still generates the majority of carbon costs for the Group (currently, 96% of our emissions are in the SA region) and is likely to do so into the medium term. However, should the Paris Agreement or Paris Aspiration start to drive policy, then carbon costs from the Group’s “rest of world” operations (i.e. US, France, Finland, Australia) becomes comparable. (Currently, there are no federal-level carbon taxes levied in the United States or in the state of Montana. We are, however, assessing an appropriate carbon price for our US operations.)

Sibanye- Stillwater chose the strategic insights and trends method for ascertaining the climate risks/ opportunities applicable to demand and pricing of our commodities. This method supports inputs for TCFD reporting, and provides strategic trends to inform predicted commodity-related demand/pricing changes. The below infographic shows demand and pricing trends in the commodities in which we have an interest, noting that revenue generation capacity will be impacted by both the effect of transition on commodity demand and the price that can be charged based on the perception of the sustainability of operations.

Trend results for other scenarios are also available Climate change mitigation Our Group technical and innovation function has as one of its focus points, to design and guide optimal energy and decarbonisation solutions across the Group, in conjunction with the regions, and foster the development of regional carbon neutrality plans. The energy and decarbonisation department (within Group Technical and Innovation) have a dedicated budget for new technology research and development; for 2022 the budget was R39.2 million and R94.3 million for 2023. Other departments also have dedicated budgets for innovation, technology, energy efficiency and battery electric vehicle development. In Q4 2023, the Group concluded energy and GHG emissions forecast modelling for regions based on the 2024 life of mine models. Various scenarios were considered, and the results indicate the feasibility of a science-based decarbonisation path, with active intervention, supporting the establishment of a revised near-term goal of a Group-wide 42% reduction in scope 1 and 2 GHG emissions by 2030 from a 2021 base (excluding Australia region). The target, endorsed by the Group Sustainability Committee in January 2024, aligns with the SBTi, and is set for submission for SBTi approval in Q2 2024. Our renewable energy projects in development will provide a total dedicated capacity of 267MW (192MW wind and 75MW solar) for our South African operations. As a result, Sibanye-Stillwater now stands as one of the market leaders in private power procurement in South Africa. A further 368MW of renewable projects are in the pipeline, pending approvals. The electrification of a our mining fleet is another important consideration for decarbonisation. The Group continues to develop an understanding of the application and feasibility of BEVs in our underground mines through a range of trials including the 2-yard BEV load-haul dumper (LHD) at Stillwater, a BEV haul truck and high-profile BEV LHDs at Burnstone, and the semi-autonomous low- profile BEV LHD at Bathopele. The latter continues to outperform its diesel equivalent on average production rate, and we are near to concluding an upgrade plan that would further enable greater effectiveness and more favourable economics. We intend to complete this process by the end of the year and upgrade the LHD in Q1 2024. GROUP SUPPLEMENTARY INFORMATION 2023 14 METRICS AND TARGETS Decarbonisation targets Sibanye-Stillwater has committed to carbon neutrality by 2040 for scope 1 and 2 emissions, and to achieve net zero by 2050 (based on our current asset profile). Our other emissions related targets include: • An SBTi scope 1 and scope 2 carbon emissions reduction of 27.3% by 2025 from a 2010 base year (set in 2019 and excludes operations acquired after 2018 ) – Target met in 2023 • An updated SBTi-aligned scope 1 and 2 carbon emissions reduction target of 42% by 2030 from a 2021 baseline (excluding the Australian operations). SBTi approval is being sought in 2024 – Target set in 2023 • The screening of suppliers to establish the most relevant purchased goods and their emissions (scope 3). The screening will cover our top 75 suppliers by spend and will be conducted by end 2025 Our ESG scorecard, which determines the sustainability component of LTIs for executives includes both scope 1 and 2 emission and water-linked targets.
