Analysis · WTM · Finance
White Mountains delivered a solid quarter with book value per share rising 4% to $2,258, driven by strong underwriting at Ark (84% combined ratio) and a 35% jump in MediaAlpha shares that added $58 million in mark-to-market gains. The company repurchased $191 million of stock at 93% of book value, signaling management sees the shares as undervalued. With $0.8 billion in undeployed capital after recent acquisitions and dividends, White Mountains has significant firepower for further buybacks or investments. The quarter also saw Kudu generate a 15% trailing return on equity and HG Global return $90 million to the parent via a dividend from its refinancing. These results reinforce the company's track record of compounding book value while actively managing capital allocation.
