Fair Value models
Bear€5.38Fair Value €6.34Bull€7.30
Price €13.94 · Downside -54.5%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then (€0.0087 per share) are deliberately not added.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.
Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card.18/100
