Approach 1: Arthur J. Gallagher Excess Returns Analysis

The Excess Returns model asks a simple question: is Arthur J. Gallagher expected to earn more on its equity than it costs to fund that equity, and for how long can that continue? Those extra profits over the required return are then added to the current book value to estimate what the stock could be worth.

For Arthur J. Gallagher, the model uses a Book Value of $92.55 per share and a Stable EPS of $15.28 per share, based on weighted future Return on Equity estimates from 4 analysts. The Average Return on Equity is 14.28%, compared with a Cost of Equity of $7.61 per share. That gap feeds into an Excess Return of $7.68 per share, and a Stable Book Value of $107.00 per share, sourced from weighted future Book Value estimates from 3 analysts.

Putting those pieces together, Simply Wall St’s Excess Returns model arrives at an intrinsic value of about $322 per share. Against a share price around $216, this framework points to the stock trading at roughly a 32.9% discount, which suggests it screens as undervalued on this measure.

Approach 2: Arthur J. Gallagher Price vs Earnings

For profitable companies, the P/E ratio is a useful way to relate what you pay for the stock to the earnings the business is currently generating. It gives a quick sense of how many dollars investors are willing to pay for each dollar of earnings.

What counts as a “normal” or “fair” P/E depends on what investors expect for future earnings growth and how they view the risks. Higher expected growth or lower perceived risk can support a higher P/E, while lower growth or higher risk usually points to a lower multiple.

Arthur J. Gallagher currently trades on a P/E of 34.45x, compared with an Insurance industry average of 10.88x and a peer average of 17.66x. Simply Wall St’s Fair Ratio for the stock is 13.62x. This Fair Ratio is a proprietary estimate of what the P/E could be given factors such as earnings growth profile, profit margins, industry, market cap and company specific risks. This makes it more tailored than a simple comparison with peers or the broad industry.

The current P/E of 34.45x is well above the Fair Ratio of 13.62x, which points to the stock looking expensive on this metric.
