Synthomer plc (SYNT) Fair Value & Analysis

Basic Materials · GB · Market cap 138M GBX

Below-average quality, screening 82% undervalued on our models.

What matters now

• The large discount to fair value meets weak quality (34/100). That raises the risk this is a value trap rather than a bargain.
• The model range is unusually wide (£0.4200 to £3.26). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis

Synthomer plc (SYNT) currently trades at £1.01, while our model-based Fair Value estimate is £1.84, implying the stock looks roughly 81.8% undervalued today. The Quality Score stands at 34/100 (below-average 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: medium), always confirm before acting.

Over the trailing twelve months, Synthomer plc generated revenue of £1.7B at a net margin of -9.0%. Revenue declined 10.3% year over year. It earns a return on equity of -14.9%. Net debt stands at £629M. Fundamentals as of Aug 13, 2026

Our scenario range runs from £0.4200 (bear case) to £3.26 (bull case); at £1.01, 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 82%, SYNT 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: Dividend Discount (£5.94) versus DCF Models (£0.0500). Highest evidence: Rev-Margin DCF (74).
