Frequently asked questions
What is White Mountains Insurance Group Ltd's revenue?
White Mountains Insurance Group Ltd's trailing twelve-month revenue is $2.82B. Revenue is the top line the whole model builds on, and at this scale the question shifts from how fast it grows to whether margins hold as it compounds.
How profitable is WTM?
In its most recent fiscal year, WTM ran a gross margin of 53.72%, an operating margin of 49.08%, and a net margin of 40.87%. Margins this high mean most of each extra dollar of revenue drops through to profit, which is the signature of real pricing power.
How much free cash flow does WTM generate?
WTM produced $-7.20M in free cash flow in its most recent fiscal year. Free cash flow is what is left after running and reinvesting in the business, and it is the cash that actually funds buybacks, dividends, and a stronger balance sheet.
Is WTM's balance sheet healthy?
WTM holds $184.90M in cash and equivalents against $837.00M in long-term debt, on $5.43B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
