Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 30, 2026.
How to read this chart
60‑month range €1.56 – €12.70 · fair‑value band €11.81 – €18.87 · the €11.42 price screens below the €15.34 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Aug 30, 2026.
Analysis
Koninklijke BAM Groep NV (BAMNB) currently trades at €11.42, while our model-based Fair Value estimate is €15.34, implying the stock looks roughly 25.6% undervalued today. The Quality Score stands at 69/100 (solid quality), in the Industrials sector. Bull case: the DCF Models group reads highest at a median of €17.05 per share, and 17 of the 24 models we run sit above the €11.42 price. Bear case: the Dividend Discount group reads lowest at €2.46, and 7 of the 24 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Koninklijke BAM Groep NV generated revenue of €7.0B at a net margin of 3.0%. Revenue grew 7.3% year over year. It earns a return on equity of 22.8%. The balance sheet holds a net cash position of €311M. Fundamentals as of Aug 30, 2026
Our scenario range runs from €11.81 (bear case) to €18.87 (bull case); at €11.42, 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 near its 52-week high and 66% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at −46% fair-value upside, at 34%, BAMNB 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 €0.3384 per share, which is 2.2 % 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 24 models by family
Widest divergence: DCF Models (€17.05) versus Dividend Discount (€2.46). Highest evidence: FCF DCF (81).

Quality Score breakdown
Of which business quality 67 · Market factors (momentum, volatility) 75
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.
