Transgene SA (TNG) Fair Value & Analysis
Healthcare · FR · Market cap €204M
Fair value as of: Aug 13, 2026
From 1 valuation models · updated yesterday
Share price −2.7% over the past month.
Below-average quality, and screening another 58% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (€0.3825). The favourable scenario is already priced in.
- Weak quality (17/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range (€0.2040 to €0.3825) leaves room in how you read the outcome.

Analysis
Transgene SA (TNG) currently trades at €0.7200, while our model-based Fair Value estimate is €0.3060, implying the stock looks roughly 57.5% overvalued today. The Quality Score stands at 17/100 (below-average quality), in the Healthcare sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: low).
Trailing-twelve-month revenue stands at €7.2M. Revenue declined 12.2% year over year. It earns a return on equity of -54.8%. The balance sheet holds a net cash position of €4.6M. Fundamentals as of Aug 13, 2026
Our scenario range runs from €0.2040 (bear case) to €0.3825 (bull case); at €0.7200, 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. The share trades about 52% below its 52-week high, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -47% fair-value upside, at -58%, TNG screens richer 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.
