Zimplats CEO Mhembere retires after 19 years, hands US$1.8bn platform to Segula
What's the deal? Alexander Mhembere is retiring as chief executive officer of Zimplats, Zimbabwe's largest platinum producer, effective November 1, 2026. His successor, Stanley Segula, a longtime operations chief with more than 18 years at the company, inherits an operation expanded through a US$1.8bn investment programme.
Why now? Mhembere joined as CEO in October 2007 and steps down after 19 years. He will stay on as chairman of Zimbabwe Platinum Mines, the operating subsidiary, preserving continuity through the transition.
What's the endgame? The US$1.8bn programme covered mine development, expanded concentrators, an upgraded Selous smelter and renewable energy. Zimplats commissioned a 35MW solar plant and a 38MW smelter expansion in FY2025, with a 185MW solar programme planned.
What could go wrong? Segula takes over a bigger platform just as costs climb. Implats reported Zimplats' unit costs up 23% in FY2026, despite higher throughput, leaving the challenge of sustaining the expanded operation without renewed cost-cutting.
The pressure is not new. A platinum-group metals price slump drove Zimplats to offer voluntary retrenchments in 2024, capped at about 1% of its workforce. The sector backdrop has since improved, but prices remain uncertain.
The signal: This is a succession story about turning heavy investment into returns. Segula's test is to prove that an expanded, more integrated operation can deliver reliable production and value without cutting back.
