Analysis

Johnson Matthey Plc (JMAT) currently trades at £21.96, while our model-based Fair Value estimate is £31.16, implying the stock looks roughly 41.9% undervalued today. The Quality Score stands at 52/100 (solid quality), in the Basic Materials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.

Over the trailing twelve months, Johnson Matthey Plc generated revenue of £12.6B at a net margin of -0.8%. Revenue grew 19.5% year over year. It earns a return on equity of -4.2%. Net debt stands at £841M. Fundamentals as of Aug 13, 2026

Our scenario range runs from £16.32 (bear case) to £50.16 (bull case); at £21.96, the current price sits within 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 -68% fair-value upside, at 42%, JMAT screens cheaper 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.

Widest divergence: Multiples (£23.00) versus Earnings-Based (£5.83). Highest evidence: Growth DCF (80).
