Analysis
Sto SE (STO3) currently trades at €96.00, while our model-based Fair Value estimate is €123.27, implying the stock looks roughly 28.4% undervalued today. The Quality Score stands at 55/100 (solid 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, Sto SE generated revenue of €1.6B at a net margin of 2.5%. Revenue declined 0.3% year over year. It earns a return on equity of 5.2%. The balance sheet holds a net cash position of €2.8M. Fundamentals as of Jul 19, 2026
Our scenario range runs from €92.45 (bear case) to €154.09 (bull case); at €96.00, 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. The share trades about 28% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -33% fair-value upside, at 28%, STO3 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 24 models by family
Widest divergence: DCF Models (€157.92) versus Dividend Discount (€38.07). Highest evidence: Growth DCF (80).

How we calculate Fair Value

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