Our scenario range runs from €11.81 (bear case) to €18.87 (bull case); at €12.03, the current price sits within 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 75% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -34% fair-value upside, at 28%, BAMNB screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted 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.
All 24 models by family
