Sibanye-Stillwater is a multinational mining and metals processing group and one of the world’s largest primary producers of platinum group metals (platinum, palladium and rhodium), alongside significant gold mining operations in South Africa and a growing battery metals business. It is listed on the Johannesburg Stock Exchange and the New York Stock Exchange.
What Does Sibanye-Stillwater Do?
Sibanye-Stillwater mines and processes precious metals across five continents. Its core PGM operations span South Africa’s Bushveld Complex and the Stillwater and East Boulder mines in Montana, USA (acquired in 2017, giving the company its current name), while its gold division operates several of South Africa’s deepest and most historically significant gold mines. The group also runs PGM autocatalyst recycling operations and has diversified into battery metals through its roughly 80% stake in the Keliber lithium project in Finland, acquired in stages beginning in 2021.
Is Sibanye-Stillwater Legit?
Yes. It is a dual-listed, JSE and NYSE-traded company publishing regular audited financial results, and it is one of the largest employers in South African mining, though it has also faced significant public scrutiny over workplace safety, given the inherent hazards of deep-level and PGM mining.
How Big Is Sibanye-Stillwater?
African Business magazine’s Top 250 Companies in Africa dataset placed Sibanye-Stillwater’s revenue at approximately $6.12 billion. The company’s fortunes improved dramatically through 2025 and into 2026 as global platinum, palladium, rhodium and gold prices rallied; its third-quarter 2025 revenue reportedly rose 198% year-on-year as a result. Its market capitalisation reached roughly $6.81 billion by mid-2026, according to StockAnalysis.com, up more than 56% over the prior year and reflecting the strong commodity price environment.
Who Is the CEO of Sibanye-Stillwater?
Richard Stewart became CEO in October 2025, succeeding Neal Froneman, the company’s founder-CEO who had led it since its creation in 2012–2013 and built it through a series of major acquisitions, including Stillwater Mining and Lonmin. Froneman subsequently took on a new role as Chairman of SuperCritical Materials, a UK-based technology company.
Who Owns Sibanye-Stillwater?
Sibanye-Stillwater is a widely held public company with no controlling shareholder, listed on both the JSE and NYSE; its shares are held by a broad mix of South African and international institutional investors following its 2013 unbundling from Gold Fields Limited.
What Has Sibanye-Stillwater Been in the News For Recently?
Beyond its 2025/2026 commodity-driven earnings surge and CEO transition, Sibanye-Stillwater has faced ongoing safety challenges typical of deep-level mining, including a May 2025 incident in which more than 260 workers were briefly trapped underground at its Kloof gold mine shaft (with no injuries reported), following a history of more serious incidents including a violent 2019 strike that resulted in nine deaths. The company has continued to press forward with diversification into battery metals via its Keliber lithium investment in Finland as part of a long-term strategy to reduce reliance on PGM and gold price cycles.
How Does Sibanye-Stillwater Compare to Its Competitors?
In platinum group metals, its main rivals are Valterra Platinum (formerly Anglo American Platinum) and Impala Platinum (Implats), both also JSE-listed South African PGM producers. In gold, it competes with AngloGold Ashanti, Gold Fields and Harmony Gold. Sibanye-Stillwater is distinctive among these peers for its dual PGM-and-gold exposure and its US Montana operations, which give it geographic diversification most South African peers lack.
