WHITE MOUNTAINS REPORTS THIRD QUARTER RESULTS
HAMILTON, Bermuda (November 6, 2025) - White Mountains Insurance Group, Ltd. (NYSE: WTM) reported book value per share of $1,851 as of September 30, 2025, an increase of 3% for the third quarter of 2025 and 6% for the first nine months of 2025, including dividends.
On October 2, 2025, White Mountains entered into an agreement to sell approximately 77% of its equity interest in Bamboo for cash to CVC Capital Partners and will retain the remainder. Including the expected fourth quarter impact from the closing of the transaction of approximately $325 per share, White Mountains’s book value per share would be $2,176 as of September 30, 2025. Bamboo’s assets and liabilities have been presented as held for sale in White Mountains’s consolidated balance sheets as of September 30, 2025 and December 31, 2024.
Manning Rountree, CEO, commented, “BVPS was up 3% in the quarter. We had good operating results and investment returns. Ark produced a 76% combined ratio and $366 million of gross written premiums in the quarter. HG Global generated $16 million of gross written premiums in the quarter and grew book value by 3%. Kudu produced a 9% return on equity on a trailing 12 months basis, growing both the fair value of its portfolio of participation contracts and EBITDA. Bamboo had another record quarter with continued strong growth in managed premiums and adjusted EBITDA. Our consolidated investment portfolio, excluding MediaAlpha, was up 2.0% with gains in both fixed income and equities. During the quarter, we closed our previously announced deployments at BroadStreet Partners and Distinguished Programs.”
Rountree continued, “In early October, we announced the sale of a control stake in Bamboo. Upon closing, the transaction will increase our book value per share by $325 and our undeployed capital position from roughly $0.3 billion to $1.1 billion.”

Gross written premiums were $2.3 billion year-to-date, up 18%, aided by the addition of new underwriting teams and classes of business.”

HG Global’s total par value of policies assumed was $850 million and $2,208 million in the third quarter and first nine months of 2025 compared to $688 million and $2,012 million in the third quarter and first nine months of 2024. HG Global’s total gross pricing was 187 and 189 basis points in the third quarter and first nine months of 2025 compared to 203 and 171 basis points in the third quarter and first nine months of 2024.

HG Global’s results included net realized and unrealized investment gains of $7 million and $20 million in the third quarter and first nine months of 2025 compared to $23 million and $13 million in the third quarter and first nine months of 2024, driven by a decrease in interest rates. HG Global’s results in the third quarter and first nine months of 2024 also included the loss on deconsolidation of $115 million, partially offset by an increase in fair value of the BAM surplus notes of $16 million during the quarter. The fair value of the BAM surplus notes was $396 million as of September 30, 2025 compared to $397 million as of June 30, 2025. The decline was driven by $8 million of principal and interest payments, largely offset by approximately $8 million of accrued interest.
Kevin Pearson, President of HG Global, said, “HG Global had a good quarter, growing book value by 3%. Par value assumed increased 24% year-over-year, driven by increased activity in both the primary and secondary markets. Pricing was down marginally quarter-over-quarter but was more than offset by higher volumes.”

We officially launched in Texas during the quarter. Given this expansion and our continued success in California, the stage is set for profitable growth for the remainder of 2025 and beyond. We’re excited to partner with CVC and White Mountains for this next chapter.”
Distinguished
On September 2, 2025, White Mountains acquired a controlling interest in Distinguished Programs, a full-service MGA and program administrator for specialty property & casualty insurance. Distinguished places insurance across a diversified portfolio of programs broadly grouped into two verticals. The ScaleCo vertical consists of established programs, primarily focused on real estate and hospitality end markets. The GrowthCo vertical consists of start-up programs, focused on a diversified set of specialty property and casualty insurance products across multiple industries. In the transaction, White Mountains paid $224 million of cash consideration, while Distinguished borrowed $50 million of incremental debt. Including its 2% previously-held interest, at closing White Mountains owned 56% of Distinguished on a basic units outstanding basis (44% on a fully-diluted/fully-converted basis, taking account of management’s equity incentives).
For the period from September 2, 2025 through September 30, 2025, Distinguished reported managed premiums of $43 million, commission and fee revenues of $14 million, pre-tax loss of $3 million, and ScaleCo adjusted EBITDA of $1 million.
Jason Rotman, President of Distinguished, said “My partners and I are very excited to be the newest members of the White Mountains family. We remain focused on driving profitable growth in our ScaleCo businesses. At the same time, we are growing and diversifying our portfolio of managed programs through the addition of new teams, with one launched this quarter and several more expected by early 2026.”
MediaAlpha
As of September 30, 2025, White Mountains owned 17.9 million shares of MediaAlpha, representing a 27% basic ownership interest (25% on a fully-diluted/fully-converted basis). As of September 30, 2025, MediaAlpha’s share price was $11.38 per share, which increased from $10.95 per share as of June 30, 2025. The carrying value of White Mountains’s investment in MediaAlpha was $203 million as of September 30, 2025 compared to $196 million as of June 30, 2025. At our current level of ownership, each $1.00 per share increase or decrease in the share price of MediaAlpha will result in an approximate $7.00 per share increase or decrease in White Mountains’s book value per share.

The equity portfolio, excluding MediaAlpha, returned 2.7%, behind the S&P 500 Index return of 8.1%. Equity results were impacted by lower relative returns from our market neutral investments and the liquidation of most of our parent company common stock portfolio in the first half of 2025 in anticipation of deployments at BroadStreet and Distinguished.”

Regulation G
This earnings release includes non-GAAP financial measures that have been reconciled from their most comparable GAAP financial measures.
•Kudu’s EBITDA, adjusted EBITDA, annualized adjusted EBITDA, annualized revenue and cash revenue yield are non-GAAP financial measures.
EBITDA is a non-GAAP financial measure that adds back interest expense on debt, income tax (expense) benefit, depreciation and amortization of other intangible assets to GAAP net income (loss).
Adjusted EBITDA is a non-GAAP financial measure that excludes certain other items in GAAP net income (loss) in addition to those added back to calculate EBITDA. The items relate to (i) net realized and unrealized investment gains (losses) on Kudu’s revenue and earnings participation contracts, (ii) non-cash equity-based compensation expense and (iii) transaction expenses. A description of each item follows:
•Net realized and unrealized investment gains (losses) - Represents net unrealized investment gains and losses recorded on Kudu’s revenue and earnings participation contracts, which are recorded at fair value under GAAP, and realized investment gains and losses from participation contracts sold during the period.
•Non-cash equity-based compensation expense - Represents non-cash expenses related to Kudu’s management compensation that are settled with equity units in Kudu.
•Transaction expenses - Represents costs directly related to Kudu’s mergers and acquisitions activity, such as external lawyer, banker, consulting and placement agent fees, which are not capitalized and are expensed under GAAP.
Annualized adjusted EBITDA is a non-GAAP financial measure that (i) annualizes partial year revenues related to Kudu’s revenue and earnings participation contracts acquired during the previous 12-month period and (ii) removes partial year revenues related to revenue and earnings participation contracts sold during the previous 12-month period.
Annualized revenue is a non-GAAP financial measure that adds the adjustments for annualized adjusted EBITDA to GAAP net investment income.
Cash revenue yield is a non-GAAP financial measure that is derived using annualized revenue as a percentage of total net capital drawn and invested. The most directly comparable GAAP financial measure is net investment income revenue yield, which is derived using GAAP net investment income as a percentage of total net capital drawn and invested.
White Mountains believes that these non-GAAP financial measures are useful to management and investors in evaluating Kudu’s performance. White Mountains also believes that annualized adjusted EBITDA is useful to management and investors in understanding the full earnings profile of Kudu’s business as of the end of any 12-month period. See page 20 for the reconciliation of Kudu’s GAAP net income (loss) to EBITDA, adjusted EBITDA and annualized adjusted EBITDA, and the reconciliation of Kudu’s GAAP net investment income to annualized revenue.
•Bamboo’s MGA pre-tax income (loss), MGA net income (loss), MGA EBITDA and MGA adjusted EBITDA are non-GAAP financial measures.
MGA pre-tax income (loss) and MGA net income (loss) are non-GAAP financial measures that exclude the results of the Bamboo captive, which is consolidated under GAAP, from Bamboo’s consolidated GAAP pre-tax income (loss) and net income (loss).
The following table presents the reconciliation from Bamboo’s consolidated GAAP pre-tax income (loss) to MGA pre-tax income (loss) for the three and nine months ended September 30, 2025 and 2024:
| | | | | | | | | | | | | | | | | | | | | | | | | | |
| | Three Months Ended September 30, | | Nine Months Ended September 30, |
| Millions | | 2025 | | 2024 | | 2025 | | 2024 |
| Bamboo’s consolidated GAAP pre-tax income (loss) | | $ | 15.0 | | | $ | 15.5 | | | $ | 37.4 | | | $ | 22.8 | |
| Remove pre-tax (income) loss, Bamboo captive | | (.1) | | | (1.9) | | | 2.7 | | | (1.9) | |
| MGA pre-tax income (loss) | | $ | 14.9 | | | $ | 13.6 | | | $ | 40.1 | | | $ | 20.9 | |
MGA EBITDA is a non-GAAP financial measure that adds back interest expense on debt, income tax (expense) benefit, depreciation and amortization of other intangible assets to MGA net income (loss).
MGA adjusted EBITDA is a non-GAAP financial measure that excludes certain other items in GAAP net income (loss) in addition to those added back to calculate MGA EBITDA. The items relate to (i) non-cash equity-based compensation expense, (ii) software implementation expenses, (iii) restructuring expenses and (iv) transaction expenses. A description of each item follows:
•Non-cash equity-based compensation expense - Represents non-cash expenses related to Bamboo’s management compensation that are settled with equity units in Bamboo.
•Software implementation expenses - Represents costs directly related to Bamboo’s implementation of new software.
•Restructuring expenses - Represents costs directly related to Bamboo’s corporate restructuring and capital planning activities.
•Transaction expenses - Represents costs directly related to the Bamboo transaction, including legal and consulting fees, which are not capitalized and are expensed under GAAP.
White Mountains believes that these non-GAAP financial measures are useful to management and investors in evaluating Bamboo’s performance. See page 22 for the reconciliation of Bamboo’s consolidated GAAP net income (loss) to MGA net income (loss), MGA EBITDA and MGA adjusted EBITDA.
•Distinguished’s ScaleCo net income (loss), ScaleCo EBITDA and ScaleCo adjusted EBITDA are non-GAAP financial measures.
ScaleCo net income (loss) is a non-GAAP financial measure that excludes the results of the GrowthCo vertical, which is consolidated under GAAP, from Distinguished’s consolidated GAAP net income (loss).
ScaleCo EBITDA is a non-GAAP financial measure that adds back interest expense on debt, income tax (expense) benefit, depreciation and amortization of other intangible assets to ScaleCo net income (loss).
ScaleCo adjusted EBITDA is a non-GAAP financial measure that excludes the non-cash equity-based compensation expense in ScaleCo GAAP net income (loss) in addition to those items added back to calculate ScaleCo EBITDA. The non-cash equity-based compensation expense represents management compensation that is settled with equity units in Distinguished.
White Mountains believes that these non-GAAP financial measures are useful to management and investors in evaluating Distinguished’s performance. White Mountains also believes that excluding the results of the GrowthCo vertical, which Distinguished views as an investment in start-up programs, is useful to understanding the performance of Distinguished’s established programs. See page 23 for the reconciliation of Distinguished’s consolidated GAAP net income (loss) to ScaleCo net income (loss), ScaleCo EBITDA and ScaleCo adjusted EBITDA.
•Total consolidated portfolio return excluding MediaAlpha and total equity portfolio return excluding MediaAlpha are non-GAAP financial measures that remove the net investment income and net realized and unrealized investment gains (losses) from White Mountains’s investment in MediaAlpha. White Mountains believes these measures to be useful to management and investors by showing the underlying performance of White Mountains’s investment portfolio and equity portfolio without regard to White Mountains’s investment in MediaAlpha. The following tables present reconciliations from GAAP to the reported percentages:
| | | | | | | | | | | | | | | | | | | | | | | | | | |
| | Three Months Ended September 30, | | Nine Months Ended September 30, |
| | 2025 | | 2024 | | 2025 | | 2024 |

However, whether actual results and developments will conform to its expectations and predictions is subject to risks and uncertainties that could cause actual results to differ materially from expectations, including:
