Frequently asked questions
Is WTM growing its revenue and profit?
Over the past 5 years, White Mountains Insurance Group Ltd's revenue has grown 33.1% per year. These are computed facts, not advice.
How much debt does WTM have?
As of FY2025, White Mountains Insurance Group Ltd reported $837M of total debt against $186M of cash.
What is WTM's profit margin?
In FY2025, gross margin was 95.9%, operating margin —, and net margin 29.6%.
What is WTM's P/E ratio?
White Mountains Insurance Group Ltd's P/E (TTM) is 4.94 as of the 2026-11-02 close — market cap ÷ net income over the trailing twelve months where four consecutive quarters are reported, otherwise the latest fiscal year, the same figure as on the WTM stock page. The valuation chart above sets each month-end's price against the latest annual net income instead, so its latest point (about 5.0× as of Nov '26) can differ. These are computed facts, not advice.
Where does this data come from?
All figures are extracted from the company’s SEC EDGAR/XBRL filings — 10-K annual reports and 10-Q quarterly reports (use the Annual / Quarterly toggle). Quarterly figures are derived from the as-filed statements (year-to-date amounts are differenced into discrete quarters). Growth rates and ratios are computed by tradmap; nothing here is investment advice.

growth rates, valuation multiples & ratios computed by tradmap. Valuation uses each month-end price
against the latest annual filing. Informational only — not investment advice.
