Analysis
SBF AG (CY1K) currently trades at €3.21, while our model-based Fair Value estimate is €0.6400, implying the stock looks roughly 80.1% overvalued today. The Quality Score stands at 58/100 (solid quality), in the Industrials 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, SBF AG generated revenue of €40.7M at a net margin of -2.9%. Revenue declined 22.7% year over year. It earns a return on equity of -3.8%. Net debt stands at €1.8M. Fundamentals as of Jul 18, 2026
Our scenario range runs from €0.4300 (bear case) to €0.8500 (bull case); at €3.21, 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 68% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -28% fair-value upside, at -80%, CY1K 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.
All 10 models by family
Widest divergence: Asset-Based (€2.10) versus Multiples (€0.6400). Highest evidence: Growth DCF (80).
