MEDIA RELEASE

Sibanye-Stillwater receives high rating for biodiversity

Johannesburg, 8 December 2021: Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW) is pleased to announce that it has been rated 4th out of 327 JSE-listed companies and 27 State-Owned Enterprises (SOEs) in the third annual National Biodiversity and Business Network of South Africa Biodiversity Disclosure Project (based on its 2020 disclosures). Sibanye-Stillwater's score improved 15% year-on-year over 2019, placing it as the 2nd best company in the basic materials sector from 3rd in 2019.

The report presents the results of the third annual corporate biodiversity performance assessment of the National Biodiversity and Business Network (NBBN) of South Africa, managed by the Endangered Wildlife Trust (EWT). Whilst only 79/354 JSE-listed companies and SOE's recognise biodiversity as a material issue, Sibanye-Stillwater recognises the core importance of biodiversity in ensuring that we prosper as a climate change resilient business by both reducing our climate impact and ensuring the health of ecosystems to promote sustainable mining mineral processing and post-miningland-uses to support communities.

Defining nature-positive actions and outcomes will take long-term commitment and require science-based assessments. Sibanye-Stillwater has partnered with the Endangered Wildlife Trust to achieve this by completing the first Biological Diversity Protocol assessment for all its operations in 2021. The assessment aims to establish baseline hectare equivalents to track, manage and disclose on biodiversity-related metrics. The outcomes of the 2021 Biological Diversity Protocol assessments will be disclosed in our 2021 integrated annual report which will be issued on 22 April 2022.

The acknowledgement of our Biodiversity performance is testament to our commitment to define globally relevant and industry leading best practices. Our commitment to embedding the mitigation hierarchy 1in all areas of the business ultimately aims at achieving net gain for our existing operations and no-net loss in biodiversity for our new operations.

CEO, Neal Froneman commented: "As a consequence of putting ESG at the centre of our strategy, it is heartening to be recognised for our biodiversity efforts and disclosures. As one of the largest primary producers of Platinum Group Metals (PGMs), which are used in the production of catalytic converters used in automobiles to remove noxious gasses from exhaust fumes, Sibanye-Stillwater is committed to expanding its role in providing a cleaner and sustainable environment and in improving lives. We recognise the need to transition to a climate change resilient business, one that not only minimises our GHG emissions and contribution to global warming but also executes on the protection and restoration of ecosystems to support resilience against the impacts of climate change, both for our business and surrounding communities."

1 The steps to be taken when deciding on all activities that may impact upon biological diversity resources. It is a step-wise approach that includes: avoidance, mitigation, restoration/ rehabilitation and off-setting. These steps should be used in conjunction with one another to achieve the best possible outcome.

More about The Endangered Wildlife Trust and the NBBN

The Endangered Wildlife Trust (EWT) has worked tirelessly since 1973 to save wildlife and habitats, with their vision being a world in which both humans and wildlife prosper in harmony with nature. The EWT's team of field-based specialists works across southern and East Africa, where committed conservation action is needed the most. Working with their partners, including businesses and governments, the EWT is at the forefront of conducting applied research, supporting community conservation and livelihoods, training and building capacity, addressing human wildlife conflict, monitoring threatened species and establishing safe spaces for wildlife range expansion. The Endangered Wildlife Trust (EWT) recognised the need for a body to assist businesses to integrate biodiversity into their strategies and activities. This led the EWT to establish the NBBN in 2013, in partnership with the Department of Environmental Affairs (now the Department of Environment, Forestry, and Fisheries), and leading SA companies. The NBBN aims to promote conservation of biodiversity by working with businesses to provide solutions which mitigate their impacts and provide opportunities to ensure sustainable business practices. Their network aims to assist business to develop and disseminate relevant tools and guidelines, while sharing experiences in an African context.
