South32 (ASX:S32) Valuation in Focus After Profit Return and New Production Guidance

Simply Wall St

If you hold shares in South32 (ASX:S32) or are thinking about taking the plunge, the company’s recent full-year earnings and ambitious production guidance are front and center right now. South32 returned to profit after last year’s loss, giving investors concrete evidence of a turnaround just as management set out detailed output forecasts for the next two years. It is a double dose of news that is prompting many to ask whether we are seeing the beginning of a shift in fortunes for this miner.

After a tough stretch earlier this year, South32’s share price has continued to ebb lower, with momentum fading over the past month and year. Even so, the latest guidance and the bounce back to profitability are fresh reasons for the market to reassess the outlook. Alongside the earnings lift and operational updates, other events this quarter, including a buyback extension and a minor dividend adjustment, have shaped sentiment but have not reversed the prevailing trend.

So after this year’s steady slide, is South32 finally looking cheap, or are these gains already built into the price?

Most Popular Narrative: 16.3% Undervalued

The most widely followed narrative views South32 as undervalued, with a consensus suggesting that its share price trades at a notable discount to fair value based on projected earnings and future growth.

Large-scale investment and progress in copper and base metals growth projects (Hermosa, expanded Sierra Gorda capacity) position South32 to benefit from rising demand for metals critical in renewables, electric vehicles, and global decarbonization. This supports revenue and future earnings growth. Realized portfolio simplification and divestiture of lower margin, higher-risk coal assets refocus South32 on higher-return and future-facing commodities, increasing long-term net margins and improving the company's risk profile in line with energy transition trends.

Ready to discover what’s behind this bullish valuation? The narrative rests on ambitious assumptions about how fast key financial drivers can accelerate, hinting at bold improvements in profit margins and efficiency. Curious how future growth in strategic metals and a huge earnings shift could shape the future share price?
