Fair Value models
Bear€378.83Fair Value €511.36Bull€703.53
Price €535.00 · Downside -4.4%
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 (€24.27 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.55/100
Spin-off in 2024: revenue and profit before it include the divested business. Growth is measured afresh from 2024.
What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate.
−2.0%
Earnings growth per share plus dividend.
Earnings per share, growth per year−2.0%
Dividend (yield on the price)0.0%
Profit margin 2020 to 2025 ⓘOperating margin then vs now, from reported annual statements. A falling margin after a boom year is the classic peak-earnings signal: the growth rate then leans on an inflated base.2% → 1%
Growth Forecast
Price in line with expectations
The price assumes about as much growth as the company has delivered so far.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
+9.8%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect
n/a
No analyst forecast available.
After inflation (euro area: IMF forecast 2.2% a year to 2030, 2.6% from 2016 to 2025) that is about +7.5% a year for the price.
AI conclusion: Stable long-term municipal concessions deliver predictable cash flows in water and wastewater, yet low profitability margins constrain returns and the energy projects add uncertainty.
Main risk: Capital outlays for developing wind parks and heating networks risk pressuring overall returns without sufficiently lifting the regulated utility profile.
Gelsenwasser runs a stable water and wastewater business under long-term municipal concessions that generate predictable cash flows. It is simultaneously developing wind parks and local heating networks, with the goal of covering its own electricity needs from renewables starting in 2028. Will these energy-transition projects mainly reinforce the core franchise through lower costs and new revenues, or will the capital outlays mainly pressure returns without lifting the overall profile?
