Fair Value models

Bear €2.85 Fair Value €3.80 Bull €4.75
Price €3.42 · Upside +11.1%
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 (€0.0515 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.

Revenue & earnings trend

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. 70/100
Revenue growth appears healthy and is supported by profitability and cash-flow quality.
Revenue growth 1 year
+2.0%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
+3.3%
Revenue growth 5 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year.

Growth Forecast

Little optimism in the price
The price assumes less growth than the company has delivered so far and less than analysts expect.
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).
−8.6%
The company could shrink this much every year for the next five years and today's price would still be justified.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+4.9%
Yearly sales growth analysts expect, extended to five years.
After inflation (euro area: IMF forecast 2.2% a year to 2030, 2.6% from 2016 to 2025) that is about −10.6% a year for the price and +2.6% for the forecasts.
Forecast 2026 (sales)+2.9%
Forecast 2027 (sales)+6.1%
Projected 2028 (sales)+5.6%

What discount rate (WACC) does the fair value of NFN use?
Our models discount NFON AG at 11.2 %: a base by market capitalisation (micro), damped by beta 0.60, country premium for Germany. The same rate applies in all 26 models.
What is a reverse DCF?
A reverse DCF turns the usual calculation around. Instead of deriving a value from assumptions, it takes today's price as given and asks: what free-cash-flow growth would a company have to deliver for exactly this price to be fair? The result is not a forecast but the expectation already priced in. For NFON AG that is -8.6 % per year for five years, then slowing evenly to 2 % by year ten, using the same discount rate (11.2 %) and the same formula as our fair value.
How much growth has NFON AG (NFN) delivered so far?
Over the past 5 years revenue at NFON AG grew +5.7 % a year. The price currently implies free-cash-flow growth of -8.6 % per year. Comparing the two shows how much confidence is in the price: if it demands more than has been delivered, the business has to accelerate for the maths to work.

What is the free cash flow yield of NFON AG (NFN)?
The free-cash-flow yield on the price is 13.91 %: that much free cash flow NFON AG produces per unit of market value. When it exceeds the discount rate of our models (11.2 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.
What is the intrinsic value of NFON AG (NFN)?
Intrinsic value and fair value mean the same thing: what the business is worth on its numbers, independent of the share price. For NFON AG it is €3.80 per share (as of Nov 9, 2026), against a price of €3.42. It is the blended result of 22 valuation models in 6 families (DCF Models, Earnings-Based, Multiples, Growth DCF, Economic Profit, Growth Earnings).

Is fair value the same as the market price of NFN?
No. The price is what the market pays today (€3.42); the fair value is what the company's own numbers justify (€3.80). For NFON AG the two are €0.3800 per share apart. That gap is exactly why we show both numbers side by side.

What is the P/E ratio of NFN?
NFON AG trades at a price-to-earnings ratio of 56.5 (as of Nov 9, 2026). A P/E on its own says little: it compares the price with ONE year of profit, while our fair value of €3.80 is built from several models across several years. Other multiples: P/B 1.1, P/S 0.7, EV/EBITDA 8.6.
How solid is the balance sheet of NFON AG (NFN)?

An expensive market is no reason to stay out and no reason to buy everything at once: keep a broad savings plan running, buy single stocks only with money you can do without, and hold part of your money liquid while the market is high. The full picture including sectors is on is it worth investing now.
What is the share price of NFON AG (NFN)?
The closing price on Nov 6, 2026 was €3.42. Our model-based fair value is €3.80, about +11% upside (undervalued). We carry closing prices from our data provider, not a live tick.
