Analysis
Antofagasta PLC (ANTO) currently trades at £39.15, while our model-based Fair Value estimate is £17.20, implying the stock looks roughly 127.6% overvalued today. The Quality Score stands at 61/100 (solid quality), in the Basic Materials sector. Bull case: the Growth Earnings group reads highest at a median of £25.71 per share, and 3 of the 16 models we run sit above the £39.15 price. Bear case: the Dividend Discount group reads lowest at £6.59, and 13 of the 16 models stay below the price. Evidence for this calculation is medium.
Over the trailing twelve months, Antofagasta PLC generated revenue of £8.6B at a net margin of 15.4%. Revenue grew 31.8% year over year. It earns a return on equity of 15.1%. Net debt stands at £5.0B. Fundamentals as of Aug 20, 2026
Our scenario range runs from £12.90 (bear case) to £21.50 (bull case); at £39.15, 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. For context, the median of 10 Basic Materials peers we cover trades at −45% fair-value upside, at −56%, ANTO screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly £0.2984 per share, which is 1.7 % 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 16 models by family
Widest divergence: Growth Earnings (£25.71) versus Dividend Discount (£6.59). Highest evidence: EPV (74).

Quality Score breakdown
Of which business quality 59 · Market factors (momentum, volatility) 58
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.
