Analysis
Bouygues SA (EN) currently trades at €44.51, while our model-based Fair Value estimate is €65.67, implying the stock looks roughly 32.2% undervalued today. The Quality Score stands at 48/100 (below-average quality), in the Industrials sector. Bull case: the Growth DCF group reads highest at a median of €88.47 per share, and 20 of the 25 models we run sit above the €44.51 price. Bear case: the Asset-Based group reads lowest at €22.63, and 5 of the 25 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Bouygues SA generated revenue of €56.5B at a net margin of 2.1%. Revenue declined 3.2% year over year. It earns a return on equity of 9.1%. Net debt stands at €10.5B. Fundamentals as of Aug 19, 2026
Our scenario range runs from €49.25 (bear case) to €84.72 (bull case); at €44.51, the current price sits below 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 16% below its 52-week high and 31% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at −52% fair-value upside, at 48%, EN screens cheaper than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly €0.7173 per share, which is 1.1 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 25 models by family
Widest divergence: Growth DCF (€88.47) versus Asset-Based (€22.63). Highest evidence: FCF DCF (80).

Quality Score breakdown
Of which business quality 46 · Market factors (momentum, volatility) 62
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
