Most Popular Narrative: 1.1% Undervalued

Compared to the last close of A$3.34, the most widely followed narrative sees South32 trading slightly under its latest fair value of A$3.38. This narrow gap highlights how sensitive the company's valuation is to even small shifts in underlying assumptions.

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, supporting revenue and future earnings growth.

Another View: Are Market Multiples Pointing to Caution?

While the fair value estimate shows South32 as undervalued, a look at market pricing tells a more expensive story. South32’s price-to-earnings ratio stands at 30.8x, which is well above both its industry average of 22.2x and a fair ratio of 30.1x. This suggests investors may already be pricing in optimistic growth, raising questions about how much upside remains if expectations are not met.
