Analysis
Vaisala Oyj (VAIAS) currently trades at €56.60, while our model-based Fair Value estimate is €33.65, implying the stock looks roughly 40.6% overvalued today. The Quality Score stands at 67/100 (solid 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: high).
Over the trailing twelve months, Vaisala Oyj generated revenue of €598M at a net margin of 10.3%. Revenue grew 1.0% year over year. It earns a return on equity of 20.6%. Net debt stands at €14.2M. Fundamentals as of Jul 20, 2026
Our scenario range runs from €21.79 (bear case) to €45.04 (bull case); at €56.60, 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 near its 52-week high and 41% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -45% fair-value upside, at -41%, VAIAS 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: Multiples (€33.75) versus Asset-Based (€6.58). Highest evidence: Growth DCF (80).
