Stock analysis

Mersen SA (MRN) currently trades at €42.04, while our model-based Fair Value estimate is €11.06, implying the stock looks roughly 280.1% overvalued today.

Valuation

Bull case: the DCF Models group reads highest at a median of €27.81 per share, and 5 of the 24 models we run sit above the €42.04 price.

Bear case: the Earnings-Based group reads lowest at €8.77, and 19 of the 24 models stay below the price. Evidence for this calculation is high.

Scenario range: €8.29 (bear) to €13.71 (bull), the price of €42.04 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target.

Quality & growth

The Quality Score stands at 48/100 (below-average quality), in the Industrials sector.

Mixed Growth: Revenue is growing, but margins or cash flow do not fully confirm the trend.

Mersen SA reported revenue of €1.2B in FY2025 versus €923M in FY2021, a compound +6.5%/yr. Reported net income was €12.8M in FY2025, compounding −30.4%/yr from FY2021.

Key figures

Market cap €932M · P/E ratio 73.8 · P/S ratio 0.80 · EPS (TTM) €0.5700 · Dividend yield 2.1% · Net margin 1.1% · Return on equity 1.5% · Return on assets (EBIT) 7.1%.

Competitive moat

Our AI-assisted moat analysis scores the competitive advantage at 42 out of 100 (low confidence).

What moves the price

The last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat.

The share trades about 4% below its 52-week high and 109% above its 52-week low, currently above its 200-day average.

For context, the median of 10 Industrials peers we cover trades at −36% fair-value upside, at −74%, MRN screens richer than that median.

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. Evidence ⓘEvidence = 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.

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. 63/100

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.

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. Basis: EBIT basis.

Growth Forecast

A lot of optimism in the price

The price assumes more growth than the company has delivered so far and more 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).

+29.8%

Yearly growth needed for the next five years to justify today's price.

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.

+5.5%

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 +27.1% a year for the price and +3.2% for the forecasts.

What discount rate (WACC) does the fair value of MRN use?

Our models discount Mersen SA at 13.7 %: a base by market capitalisation (small), damped by beta 1.64, country premium for France. 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 Mersen SA that is +29.8 % per year a year over ten years, using the same discount rate (13.7 %) and the same formula as our fair value.

How much growth has Mersen SA (MRN) delivered so far?

Over the past 5 years revenue at Mersen SA grew +7.0 % a year. The price currently implies +29.8 % per year free-cash-flow growth a 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.

How fast is the sector of Mersen SA (MRN) growing?

The median revenue growth in the sector is +4.7 % a year. That is the yardstick for the growth priced into Mersen SA (+29.8 % per year a year): it shows whether the expectation is within the usual range or beyond it.

What is the free cash flow yield of Mersen SA (MRN)?

The free-cash-flow yield on the price is 3.83 %: that much free cash flow Mersen SA produces per unit of market value. When it exceeds the discount rate of our models (13.7 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.

What is the intrinsic value of Mersen SA (MRN)?

Intrinsic value and fair value mean the same thing: what the business is worth on its numbers, independent of the share price. For Mersen SA it is €11.06 per share (as of Sep 23, 2026), against a price of €42.04. It is the blended result of 24 valuation models (cash flow, earnings, asset, dividend).

Is Mersen SA stock overvalued or undervalued in 2026?

As of Sep 23, 2026, MRN trades above its calculated fair value: price €42.04, fair value €11.06, a gap of about −74% (overvalued). The calculation is refreshed with each new quarterly report, so the verdict can change during the year.

Is fair value the same as the market price of MRN?

No. The price is what the market pays today (€42.04); the fair value is what the company's own numbers justify (€11.06). For Mersen SA the two are €30.98 per share apart. That gap is exactly why we show both numbers side by side.

How much is Mersen SA worth?

Our models span a range for Mersen SA: cautious scenario €8.29, base €11.06, optimistic €13.71 per share (as of Sep 23, 2026, price €42.04). The range comes from different growth and margin assumptions, not from analyst opinions.

What is the P/E ratio of MRN?

Mersen SA trades at a price-to-earnings ratio of 73.8 (as of Sep 23, 2026). A P/E on its own says little: it compares the price with ONE year of profit, while our fair value of €11.06 is built from several models across several years. Other multiples: PEG 4.7, P/B 1.4, P/S 0.9, EV/EBITDA 7.7.

What is the PEG ratio of MRN?

The PEG ratio of Mersen SA is 4.72 (P/E divided by earnings growth, as of Sep 23, 2026). That is above 1, so the growth is already paid for in the price.

How solid is the balance sheet of Mersen SA (MRN)?

Is it still worth investing in stocks now?

The global stock market currently sits 14.1 % above its aggregate fair value. Mersen SA itself currently trades above fair value. 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 Mersen SA (MRN)?

The closing price on Sep 23, 2026 was €42.04. Our model-based fair value is €11.06, about −74% upside (overvalued). We carry closing prices from our data provider, not a live tick.

What should I pay attention to with Mersen SA right now?
