Approach 1: Arthur J. Gallagher Excess Returns Analysis

The Excess Returns model looks at how much profit a company is expected to generate over and above the return that equity investors typically require, then capitalises that stream of “excess” earnings into a value per share.

For Arthur J. Gallagher, the inputs are grounded in its equity base and earnings power. Book value is $90.74 per share and the stable earnings per share used in the model are $15.97, based on weighted future Return on Equity estimates from 4 analysts. The cost of equity is set at $7.75 per share, so the implied excess return is $8.22 per share. That is supported by an average Return on Equity of 14.39% and a stable book value assumption of $111.02 per share, sourced from 2 analysts’ book value estimates.

Running these figures through the Excess Returns framework produces an intrinsic value estimate of about $341.51 per share. Compared with the current share price of roughly $223, the model implies the stock is 34.7% undervalued on this basis.

Result: UNDERVALUED

Approach 2: Arthur J. Gallagher Price vs Earnings

P/E is a useful way to look at a profitable company because it links what you pay directly to each dollar of earnings, which is ultimately what supports shareholder returns over time. A higher P/E usually reflects higher growth expectations or lower perceived risk, while a lower P/E can point to more modest growth assumptions or higher uncertainty.

Arthur J. Gallagher is currently trading on a P/E of 38.36x. That sits above the Insurance industry average of 11.76x and also above the peer group average of 20.04x, which on simple comparisons might suggest a richer pricing than many sector peers.

Simply Wall St’s Fair Ratio for Arthur J. Gallagher is 14.92x. This is a proprietary estimate of what a P/E might look like given the company’s earnings growth profile, industry, profit margins, market cap and risk characteristics. That makes it more tailored than a straight comparison with broad industry or peer averages, which do not adjust for company specific strengths or weaknesses. Set against the actual P/E of 38.36x, the Fair Ratio indicates the shares screen as overvalued on this metric.

Result: OVERVALUED
