Analysis
Soitec SA (SOI) currently trades at €122.15, while our model-based Fair Value estimate is €72.94, implying the stock looks roughly 40.3% overvalued today. The Quality Score stands at 48/100 (below-average quality), in the Technology 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: medium).
Over the trailing twelve months, Soitec SA generated revenue of €592M at a net margin of -37.2%. Revenue declined 34.7% year over year. It earns a return on equity of -15.2%. Net debt stands at €58.0M. Fundamentals as of Jul 17, 2026
Our scenario range runs from €53.90 (bear case) to €92.00 (bull case); at €122.15, 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 39% below its 52-week high, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -75% fair-value upside, at -40%, SOI 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 10 models by family
Widest divergence: DCF Models (€42.95) versus Asset-Based (€24.87). Highest evidence: Growth DCF (80).

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