Analysis
London Security plc (LSC) currently trades at £35.00, while our model-based Fair Value estimate is £40.73, implying the stock looks roughly 16.4% undervalued today. The Quality Score stands at 74/100 (solid quality), in the Industrials 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, London Security plc generated revenue of £244M at a net margin of 9.7%. Revenue grew 16.0% year over year. It earns a return on equity of 14.6%. The balance sheet holds a net cash position of £37.6M. Fundamentals as of Jul 13, 2026
Our scenario range runs from £30.55 (bear case) to £50.92 (bull case); at £35.00, 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 Industrials peers we cover trades at 10% fair-value upside, at 16%, LSC 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.
All 26 models by family
Widest divergence: DCF Models (£60.72) versus Asset-Based (£9.38). Highest evidence: Growth DCF (80).
