Is Mercury General Still Cheap on Excess Returns?

The Excess Returns model starts from what Mercury General earns on shareholder capital rather than just projecting cash flows. With book value at $51.20 per share and a stable book estimate of $33.63 per share, the framework is anchored in what the balance sheet can support over time rather than a single strong year.

What stands out for Mercury General is the spread between what it is estimated to earn and what it is assumed to require. Stable EPS is put at $7.04 per share, while the cost of equity is $2.43 per share, leaving an excess return of $4.61 per share. That is consistent with an average return on equity of 20.95%, which is materially higher than many insurers typically target. This helps explain why the Excess Returns model places the estimated intrinsic value substantially above the current share price of $102.51. For readers comparing this with other insurers, the key point is that this approach values the stock on the durability of those excess returns rather than headline premium growth.
