White Mountains Reports Q1 2025 Results
White Mountains Insurance Group, Ltd. reported book value per share of $1,752 as of March 31, 2025, a slight increase for the first quarter of 2025, including dividends.
Manning Rountree, CEO, commented, “Book value per share ended the quarter at $1,752, up slightly. We had solid operating results and good investment returns, partially offset by the share price decline at MediaAlpha. Ark posted a 94% combined ratio and wrote $1.1 billion of gross written premiums, up 27% year-over-year.
“HG Global generated $7 million of gross written premiums and grew equity by 3% in the quarter. At Kudu, trailing 12 months EBITDA increased, and the fair value of the portfolio grew 4% on a same store basis. Bamboo delivered another great quarter, doubling managed premiums on a trailing 12 months basis and tripling MGA adjusted EBITDA year-over-year, while also successfully renewing its largest reinsurance program. MediaAlpha’s share price declined 18% in the quarter, producing a $37 million mark-to-market loss.
“Excluding MediaAlpha, the investment portfolio returned 2.3%, with gains in both equities and fixed income. In April, we made new capital deployments into BroadStreet Partners and Enterprise Solutions, our first acquisition at WTM Partners. Including these deployments and expected operating company distributions, undeployed capital now stands at roughly $550 million.”
