Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Sep 5, 2026.
How to read this chart
60‑month range A$2.28 – A$5.25 · fair‑value band A$0.9700 – A$1.47 · the A$5.19 price screens above the A$1.29 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Sep 5, 2026.
Analysis
South32 Limited (S32) currently trades at A$5.19, while our model-based Fair Value estimate is A$1.29, implying the stock looks roughly 302.3% overvalued today. The Quality Score stands at 62/100 (solid quality), in the Basic Materials sector. Bull case: the DCF Models group reads highest at a median of A$1.43 per share, and 0 of the 21 models we run sit above the A$5.19 price. Bear case: the Earnings-Based group reads lowest at A$0.5400, and 21 of the 21 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, South32 Limited generated revenue of A$5.9B at a net margin of 5.4%. Revenue declined 2.6% year over year. It earns a return on equity of 4.2%. The balance sheet holds a net cash position of A$42.0M. Fundamentals as of Sep 5, 2026
Our scenario range runs from A$0.9700 (bear case) to A$1.47 (bull case); at A$5.19, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades near its 52-week high and 112% above its 52-week low, currently above its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at −37% fair-value upside, at −75%, S32 screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 12 months have passed since. In that time the company retained roughly A$0.0550 per share, which is 4.3 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small. Every input is real reported data, nothing guessed.
All 21 models by family
Widest divergence: DCF Models (A$1.43) versus Earnings-Based (A$0.5400). Highest evidence: FCF DCF (81).

Quality Score breakdown
Of which business quality 61 · Market factors (momentum, volatility) 77
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
