Sompo Holdings, Inc. (8630.T) fair value

ACCE thesis

Sompo Holdings writes Japanese property and casualty insurance through Sompo Japan and Sompo International, with its Japanese retail motor and fire lines plus a Bermuda-to-London specialty book that gives it exposure to global commercial risk. The core advantage is scale in Japan, where long-standing distribution through agency networks and bancassurance partners protects a franchise that is hard to replicate. The reported 32.6% revenue growth is the number to test, since it points to premium repricing and a larger international book rather than a one-off, and the 13.6% operating margin and 14.4% ROE show that growth is coming with returns. The forward P/E of 25.6 sits above the trailing 21.2, so the market is paying up for earnings to keep rising, which makes the next few quarters of underwriting results and Sompo International's loss ratios the items to check before going further.
