Stillwater Transaction Rationale

Strong Transaction rationale 35 This transaction is expected to position Sibanye as a premier global gold and PGM mining company at a favourable point in the cycle Enhances the asset base - becoming a globally competitive South African mining champion Adds two low-cost, low-risk, steady state, producing PGM mines Expands Sibanye’s portfolio with high-grade reserves that support over 25 years of mine life Near term, organic, low-cost growth provided through the Blitz Project Extensive regional resources provide significant upside and growth potential Metallurgical processing complex – creating a mine-to-market PGM business One of largest global PGM recyclers, providing steady margin and strategic insight into PGM markets Potential to further optimise operations through transfer of “best practices” of both organisations Positions Sibanye shareholders for potential valuation re-rating Transforms Sibanye’s portfolio operationally and geographically into a stable mining jurisdiction Positions Sibanye’s Platinum Division further down the global cost curve – further cost reductions likely Enhances Sibanye’s cash flow generation to sustain industry-leading dividend Improves access to lower cost global financing Immediately accretive to NAV per management diligence and over time expected to be accretive to cash flow

Strong culture fit 36 Employees and safety Focus on proactive safety and health systems to reduce loss and to promote improvement Environmental excellence State-of-the-art systems and treatment facilities Strive to exceed environmental standards Signatory to a voluntary Good Neighbour Agreement with local community Community engagement Sustained investment into local communities through donations to several local foundations Provide access to higher education through scholarships Sibanye Stillwater
