Analysis
AIB Group (A5G) currently trades at €10.61, while our model-based Fair Value estimate is €13.11, implying the stock looks roughly 23.6% undervalued today. The Quality Score stands at 71/100 (solid 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: high), always confirm before acting.
Over the trailing twelve months, AIB Group generated revenue of €4.3B at a net margin of 49.3%. Revenue declined 11.1% year over year. It earns a return on equity of 14.2%. The balance sheet holds a net cash position of €35.2B. Fundamentals as of Jul 25, 2026
Our scenario range runs from €9.83 (bear case) to €16.39 (bull case); at €10.61, 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 76% above its 52-week low, currently above its 200-day average. For context, the median of 10 Financial Services peers we cover trades at 42% fair-value upside, at 24%, A5G screens richer 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 4 models by family
Widest divergence: Multiples (€9.70) versus Asset-Based (€4.64). Highest evidence: Residual Income (76).

How we calculate Fair Value

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
