Analysis
Santos Limited (STO) currently trades at A$8.04, while our model-based Fair Value estimate is A$3.12, implying the stock looks roughly 61.2% overvalued today. The Quality Score stands at 51/100 (solid quality), in the Energy sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, Santos Limited generated revenue of A$4.9B at a net margin of 16.6%. Revenue declined 11.6% year over year. It earns a return on equity of 5.2%. Net debt stands at A$7.0B. Fundamentals as of Aug 13, 2026
Our scenario range runs from A$2.21 (bear case) to A$4.06 (bull case); at A$8.04, 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 about 2% below its 52-week high and 39% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at -35% fair-value upside, at -61%, STO screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted 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.
All 23 models by family
Widest divergence: Asset-Based (A$3.23) versus Growth DCF (A$0.9900). Highest evidence: Growth DCF (80).
