The Excess Returns approach starts by asking whether Arthur J. Gallagher earns more on shareholders’ equity than it costs to fund that equity. On the model’s inputs, book value sits at $92.54 per share and is projected to settle closer to a stable book value of $106.90 per share, while stable EPS is set at $15.58 per share based on estimates from 4 analysts. The cost of equity is put at $7.74 per share against an excess return of $7.85 per share, with an average projected return on equity of 14.58%, which together suggest the firm is expected to generate a spread over its funding cost rather than just cover it.
Because of this excess return stream, the Excess Returns projections put Arthur J. Gallagher's estimated intrinsic value meaningfully above the current share price of $268.20. The strong Q3 2026 report, with 18% revenue growth and a 25% increase in net earnings, helps explain why a model built on sustained returns on equity sees more value than the market price implies.
