South32

South32 is a global diversified mining and metals company headquartered in Perth, Australia. The company produces a range of commodities including aluminium, metallurgical coal, manganese, nickel, silver, lead and zinc, operating mines, smelters and refineries across Australia, southern Africa and the Americas. South32 was created in 2015 when it was spun out of BHP, inheriting a portfolio of mature, long-life assets that had been part of BHP's operations. The company is listed on the Australian Securities Exchange, the London Stock Exchange and the Johannesburg Stock Exchange. In South Africa, South32's principal assets include a 60% stake in Samancor Chrome, one of the world's largest ferrochrome producers, and the Hillside aluminium smelter in KwaZulu-Natal. South32 employs thousands of people globally and generates annual revenue in the billions of dollars. The company's strategy focuses on operating excellence, capital discipline and returns to shareholders through dividends and share buybacks. South32 has pursued selective growth projects and divestments to optimise its portfolio, including the sale of its South African Energy Coal business. The company is also investing in base metals critical to the energy transition, positioning itself for long-term demand trends in electrification and decarbonisation.
