Fair value as of: Aug 6, 2026
From 6 valuation models · updated 5 days ago
Fair value updated Aug 6, 2026, revised from €714.00 to €740.00 (+3.6%) since Jul 25, 2026. Share price +12.4% over the past month.
Below-average quality, screening 85% undervalued on our models.
What matters now
- The price is below even our cautious bear case (€453.76). The market is more pessimistic than our downside scenario.
- The model range is unusually wide (€453.76 to €1,302). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- Solid quality (45/100) at a price below fair value, the discount is the argument here, not the business quality.

How to read this chart
60‑month range €299.77 – €1,694 · fair‑value band €453.76 – €1,302 · the €400.00 price screens below the €740.00 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 6, 2026.
Analysis
Banque nationale de Belgique SA (BNB) currently trades at €400.00, while our model-based Fair Value estimate is €740.00, implying the stock looks roughly 85.0% undervalued today. The Quality Score stands at 45/100 (below-average quality), in the Financial Services sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: low), always confirm before acting.
Net debt stands at €319B. Fundamentals as of Aug 6, 2026
Our scenario range runs from €453.76 (bear case) to €1,302 (bull case); at €400.00, 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 17% below its 52-week high and 16% above its 52-week low, currently below its 200-day average. For context, the median of 10 Financial Services peers we cover trades at 42% fair-value upside, at 85%, BNB 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 6 models by family
Widest divergence: Asset-Based (€42,278) versus Multiples (€994.44). Highest evidence: Growth DCF (72).
