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.

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.

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.

Regional challenges include unemployment, low levels of education, and lack of service delivery. We are mobilising partnerships and investments to strengthen institutional capacity. Our Beatrix operation remains one of the largest employers in the Masilonyana and Matjhabeng local municipalities. In terms of the environment, we are committed to limiting our impact and accelerating our decarbonisation efforts through various renewable projects.

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.
