What matters now
- The price sits above even our optimistic bull case ($80.31). The favourable scenario is already priced in.
- Weak quality (40/100) and above fair value at the same time, the margin of safety is missing on both counts.
- For a financial, book-value and earnings-based methods matter more than a cash-flow DCF, which fits banks and insurers poorly.

Analysis
Arthur J Gallagher & Co (AJG) currently trades at $266.66, while our model-based Fair Value estimate is $64.24, implying the stock looks roughly 315.1% overvalued today. The Quality Score stands at 40/100 (below-average quality), in the Financial Services sector. Bull case: the Economic Profit group reads highest at a median of $75.71 per share, and 0 of the 6 models we run sit above the $266.66 price. Bear case: the Dividend Discount group reads lowest at $41.79, and 6 of the 6 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Arthur J Gallagher & Co generated revenue of $14.2B at a net margin of 11.4%. Revenue grew 34.6% year over year. It earns a return on equity of 7.0%. Net debt stands at $12.6B. Fundamentals as of Aug 31, 2026
Our scenario range runs from $48.19 (bear case) to $80.31 (bull case); at $266.66, the current price sits above 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 20% below its 52-week high and 40% 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 −76%, AJG screens richer 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 $2.39 per share, which is 3.7 % 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 6 models by family
Widest divergence: Economic Profit ($75.71) versus Dividend Discount ($41.79). Highest evidence: Residual Income (76).

Quality Score breakdown
Of which business quality 41 · Market factors (momentum, volatility) 58
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.
