South32  (ASX:S32) Net Margin % Explanation

Although Net Income and Earnings-per-Share (EPS) are the most widely used parameter in measuring a company's profitability and valuation, it is the least reliable. The reason is that reported earnings can be manipulated easily by adjusting any numbers such as Depreciation, Depletion and Amotorization and non-recurring items.

But the long term trend of the net margin is a good indicator of the competitiveness and health of the business.

South32 Business Description

Address 100 Street Georges Terrace, Level 2, Perth, WA, AUS, 6000
South32 was born of the demerger of noncore assets from BHP in 2015. Its major operations include alumina businesses in Australia and Brazil, aluminum in Brazil, South Africa, and Mozambique, and manganese businesses in Australia and South Africa. It sold New South Wales metallurgical coal in August 2024 and the Cerro Matoso nickel mine in Colombia in December 2025. It also owns the Cannington silver/lead/zinc mine in Queensland. Its Australian manganese operations deliver high returns, but have a relatively short reserve life. The company acquired Arizona Mining, which brings with it the high-grade and likely low-cost Taylor project in the US, and also entered the copper business in 2022 via the purchase of a 45% stake in the Sierra Gorda mine in Chile.
