I checked Root’s $ROOT Q3 against the base and bear cases from my August update, after the car insurer fell 24.1% in two days. $ROOT bought back 290,694 shares in Q3 at an average of $53.15/share ($15.5M), leaving $38.8M on the authorization, ~6% of today’s market cap. At $43.37/share, the market cap is $659M on 15.2M shares, or 2.0x the $327.0M book value as of September 30. Net of the $261.6M held outside the insurance subsidiaries, you’re paying $397M for the insurance operations, or 3.9x nine-month net income annualized (Q4 is the seasonally weak quarter). In August, my base case was $55-80/share (2.5-3.5x book on an 18-22% ROE), and my bear case $35-45 (1.5-2.0x book, with ROE compressing to 12-15%). Q3’s annualized ROE was ~18%, the bottom of the base case, while the stock now trades at the top of the bear case’s multiple.
