MEDIA RELEASE

Sibanye-Stillwater achieves joint first place in the 2023 sustainability data transparency index research report

Johannesburg, 23 August 2023: Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW) is pleased to announce that it has achieved joint first place in both the metals and mining sector category and joint first place "overall" in the 2023 sustainability data transparency index (SDTI) research report compiled by Integrated reporting & assurance services (IRAS).

The SDTI is compiled annually by IRAS and the current results are based on the Sibanye-Stillwater Group's 2022 disclosures published in April 2023 (its Integrated report and the supplements of its suite of reports). The Group scored 90.75% for the 2023 STDI - significantly higher than the mining and metals sector's average rating of 64.5%, resulting in the top rating, further improving last year's ranking of being third overall and the top- rated in the mining sector.

The SDTI report is the outcome of comprehensive research by IRAS to shed light on the extent to which JSE listed companies are providing stakeholders with transparent and comparable (Environmental, Social, and Governance (ESG)/ sustainability data. The research covers various data points across 104 ESG/Sustainability indicators, evaluating 270 JSE listed companies.

Neal Froneman, CEO of Sibanye-Stillwater, expressed, "We are delighted and encouraged to receive recognition for our ongoing enhancements in reporting and disclosures, not only topping first place in our sector, but also the overall category, ahead of 268 companies from various sectors. This is a testament to our dedication to transparency, sustainability and embedding ESG in the way we do business."

Ends.
