Update on cyber security attack on Sibanye-Stillwater’s global operations

Due to the cyber-attack, which remains under investigation, we further enhanced our IT security and implemented a phased system start-up approach to ensure the protection of our environment, enabling mining and extraction operations to continue globally with minimal disruption. The Columbus metallurgical complex at the US PGM operations has however experienced some short-term operational delays, due to IT outages affecting the smelting of underground concentrate and the recycling of spent autocatalysts, but is expected to quickly resume full operations, with accumulated stockpiles expected to be processed in due course. 

Although the cyber-attack has had limited impact on our core operations, it caused temporary system outages which resulted in the implementation of back-up manual processes on certain systems at the operations. The Group’s systems are largely now restored, however, the publication of Group operating and financial results for the period ended 30 June 2024 (H1 2024), will be delayed, and the announcement and presentation have been rescheduled to Thursday, 12 September 2024. 

Neal Froneman, CEO of Sibanye-Stillwater said: “We have prioritised the health and safety of our employees as we have worked diligently to remediate the effects of the attack and normalise our operations. We are pleased to have largely secured the sustainability and integrity of our systems and continue to work closely with our customers and suppliers to mitigate any potential business interruptions that may occur in the short term. We wish to thank all our partners and advisors for their commitment and combined efforts, which have contributed to this outcome.”   

Further updates will be provided as necessary.
