What matters now

  • The price is below even our cautious bear case (£0.1656). The market is more pessimistic than our downside scenario.
  • Solid quality (49/100) at a price below fair value, the discount is the argument here, not the business quality.
  • A fairly wide model range (£0.1656 to £0.3632) leaves room in how you read the outcome.

Analysis

SIG plc (SHI) currently trades at £0.0854, while our model-based Fair Value estimate is £0.2573, implying the stock looks roughly 201.3% undervalued today. The Quality Score stands at 49/100 (below-average 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, SIG plc generated revenue of £2.6B at a net margin of -2.5%. Revenue declined 0.6% year over year. It earns a return on equity of -42.7%. Net debt stands at £520M. Fundamentals as of Aug 13, 2026

Our scenario range runs from £0.1656 (bear case) to £0.3632 (bull case); at £0.0854, the current price sits below 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 -42% fair-value upside, at 201%, SHI 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.

Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
