MEDIA RELEASE

Sibanye-Stillwater receives top tier rating from CDP on its first Water submission and another high rating for its carbon disclosure

Johannesburg, 14 December 2021: Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW) is pleased to announce that it received an average 'A-' rating1 for its 'Water Security' by CDP, a non-profit global environmental disclosure platform. It was the first time that the Group participated in the Water Security category and benchmarks higher than the Global and Africa regional average of 'B', and the metallic mineral mining sector average of 'B-'.

For the Group's annual Carbon disclosure to CDP, Sibanye-Stillwater received an average 'B' rating2 ranking it among 28% of total companies that achieved 'B' ratings in its activity group with no 'A' list ratings awarded this year in the Metallic mineral mining activity group.

Sibanye-Stillwater's 2021 Water and Carbon CDP disclosure submission documents are available at www.sibanyestillwater.com/sustainability/environment/for reference.

CEO, Neal Froneman commented: "We are very pleased about the continuous recognition from the CDP for our climate change actions and disclosures, which we are committed to further intensify as we work towards our carbon target of being net zero by 2040. Through our understanding of the interdependencies between climate change and water security we are better placed to reduce risk, support local communities and drive actions towards building a sustainable climate change resilient business.
