ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

On February 7, 2024, White Mountains Insurance Group, Ltd. issued a press release announcing its results for the year ended December 31, 2023. The press release furnished herewith is attached as Exhibit 99.1 to this Form 8-K.
Certain information included in the press release constitutes non-GAAP financial measures (as defined in Regulation G of the Securities and Exchange Commission). Specifically, there are eight non-GAAP financial measures: (i) adjusted book value per share, (ii) Kudu’s EBITDA, (iii) Kudu’s adjusted EBITDA, (iv) Kudu’s annualized adjusted EBITDA, (v) Kudu’s annualized revenue, (vi) Kudu’s cash revenue yield, (vii) total consolidated portfolio return excluding MediaAlpha and (viii) total equity portfolio return excluding MediaAlpha. These non-GAAP financial measures have been reconciled from their most comparable GAAP financial measures.
Adjusted book value per share is a non-GAAP financial measure which is derived by adjusting (i) the GAAP book value per share numerator and (ii) the common shares outstanding denominator, as described below. The GAAP book value per share numerator is adjusted (i) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global and (ii) to include a discount for the time value of money arising from the modeled timing of cash payments of principal and interest on the BAM surplus notes. The value of HG Global’s unearned premium reserve, net of deferred acquisition costs, was $195 million, $187 million, $179 million and $172 million as of December 31, 2023, September 30, 2023, December 31, 2022 and September 30, 2022, respectively. Under GAAP, White Mountains is required to carry the BAM surplus notes, including accrued interest, at nominal value with no consideration for time value of money. Based on a debt service model that forecasts operating results for BAM through maturity of the surplus notes, the present value of the BAM surplus notes, including accrued interest and using an 8% discount rate, was estimated to be $91 million, $93 million, $98 million and $114 million less than the nominal GAAP carrying values as of December 31, 2023, September 30, 2023, December 31, 2022 and September 30, 2022, respectively. White Mountains believes these adjustments are useful to management and investors in analyzing the intrinsic value of HG Global, including the value of the in-force business at HG Re, HG Global’s reinsurance subsidiary, and the value of the BAM surplus notes. The denominator used in the calculation of adjusted book value per share equals the number of common shares outstanding adjusted to exclude unearned restricted common shares, the compensation cost of which, at the date of calculation, has yet to be amortized. Restricted common shares are earned on a straight-line basis over their vesting periods. The reconciliation of GAAP book value per share to adjusted book value per share is included on page 7 of Exhibit 99.1 to this Form 8-K.
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 excludes interest expense on debt, income tax (expense) benefit, depreciation and amortization of other intangible assets from 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 excluded from EBITDA. The adjustments 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 adjustment 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. 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 18 of Exhibit 99.1 to this Form 8-K 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.

2


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.

WHITE MOUNTAINS REPORTS FOURTH QUARTER RESULTS

HAMILTON, Bermuda (February 7, 2024) - White Mountains Insurance Group, Ltd. (NYSE: WTM) reported book value per share of $1,656 and adjusted book value per share of $1,704 as of December 31, 2023. Book value per share and adjusted book value per share both increased 7% in the fourth quarter of 2023 and 14% in the year ended December 31, 2023, including dividends.

Manning Rountree, CEO, commented, “We had a strong fourth quarter to cap off a good year. ABVPS was up 7% in the quarter and 14% for the full year. In the quarter, we had good results from our operating companies and excellent returns in our investment portfolio. BAM produced $48 million of gross written premiums and member surplus contributions in the quarter. Ark produced good underwriting results in both the quarter and the full year, while growing full-year gross written premiums by 31%. Kudu grew the fair value of its continuing portfolio and closed two new deployments in the quarter. Our investment portfolio was up 6% in the quarter and 11% for the year. The value of our MediaAlpha position grew $66 million in the quarter and $27 million for the year. We redeployed $130 million into Outrigger Re for the coming year and closed on our acquisition of Bamboo in early January. Undeployed capital stands at roughly $500 million.”

Comprehensive income attributable to common shareholders was $288 million and $511 million in the fourth quarter and year ended December 31, 2023 compared to $40 million and $788 million in the fourth quarter and year ended December 31, 2022. Results in the fourth quarter and year ended December 31, 2023 included $66 million and $27 million of unrealized investment gains (losses) from White Mountains’s investment in MediaAlpha compared to $20 million and $(93) million in the fourth quarter and year ended December 31, 2022. Results in the year ended December 31, 2022 also included the net gain from the sale of NSM of $876 million.

On December 27, 2023, Bermuda enacted a 15% corporate income tax that will generally become effective on January 1, 2025. White Mountains expects to meet the requirements to be exempt from the Bermuda corporate income tax and the Pillar Two worldwide minimum tax until January 1, 2030. The Bermuda legislation also provides for an economic transition adjustment that will reduce future years’ taxable income. Under U.S. GAAP, this economic transition adjustment was required to be recognized in 2023 and led to the recording of a deferred tax asset as of December 31, 2023. Accordingly, White Mountains’s results in the fourth quarter and year ended December 31, 2023 included a net deferred tax benefit of $68 million related to the economic transition adjustment, of which $51 million was recorded at Ark and $17 million was recorded at HG Global. This tax benefit increased both book value per share and adjusted book value per share by approximately $14, net of noncontrolling interest and the impact on the fair value of Ark’s contingent consideration.

HG Global/BAM

BAM’s gross written premiums and member surplus contributions (MSC) collected were $48 million and $131 million in the fourth quarter and year ended December 31, 2023 compared to $38 million and $147 million in the fourth quarter and year ended December 31, 2022. BAM insured municipal bonds with par value of $5.1 billion and $15.6 billion in the fourth quarter and year ended December 31, 2023 compared to $2.6 billion and $16.0 billion in the fourth quarter and year ended December 31, 2022. Total pricing was 93 and 84 basis points in the fourth quarter and year ended December 31, 2023 compared to 148 and 91 basis points in the fourth quarter and year ended December 31, 2022. BAM’s total claims paying resources were $1,501 million as of December 31, 2023 compared to $1,474 million as of September 30, 2023 and $1,423 million as of December 31, 2022.

Seán McCarthy, CEO of BAM, said, “BAM recorded its strongest quarter of the year for par insured, total premiums, and pricing. Total claims-paying resources exceeded $1.5 billion for the first time. New issuance of municipal bonds increased as interest rates declined from recent highs. Investor demand for insured bonds remained robust, with insured penetration in the primary market reaching a new post-Great Recession high.”

HG Global reported pre-tax income (loss) of $34 million and $56 million in the fourth quarter and year ended December 31, 2023 compared to $12 million and $(23) million in the fourth quarter and year ended December 31, 2022. HG Global’s results included net realized and unrealized investment gains (losses) of $25 million and $14 million in the fourth quarter and year ended December 31, 2023 compared to $5 million and $(53) million in the fourth quarter and year ended December 31, 2022, driven by the movement of interest rates.

White Mountains reported pre-tax loss related to BAM of $0.4 million and $58 million in the fourth quarter and year ended December 31, 2023 compared to $14 million and $112 million in the fourth quarter and year ended December 31, 2022. BAM’s results included net realized and unrealized investment gains (losses) of $19 million and $13 million in the fourth quarter and year ended December 31, 2023 compared to $3 million and $(53) million in the fourth quarter and year ended December 31, 2022, driven by the movement of interest rates.

BAM is a mutual insurance company that is owned by its members. BAM’s results are consolidated into White Mountains’s GAAP financial statements and attributed to noncontrolling interests.

Premiums grew 31% year over year, including risk adjusted rate change of 15%. Growth was particularly strong in the property line of business, aided by the rate environment and capacity from Outrigger Re. In December, AM Best affirmed Ark’s ‘A/stable’ rating.

Regulation G

This earnings release includes non-GAAP financial measures that have been reconciled from their most comparable GAAP financial measures.
Adjusted book value per share is a non-GAAP financial measure which is derived by adjusting (i) the GAAP book value per share numerator and (ii) the common shares outstanding denominator, as described below.

The GAAP book value per share numerator is adjusted (i) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global and (ii) to include a discount for the time value of money arising from the modeled timing of cash payments of principal and interest on the BAM surplus notes.

The value of HG Global’s unearned premium reserve, net of deferred acquisition costs, was $195 million, $187 million, $179 million and $172 million as of December 31, 2023, September 30, 2023, December 31, 2022 and September 30, 2022, respectively.

Under GAAP, White Mountains is required to carry the BAM surplus notes, including accrued interest, at nominal value with no consideration for time value of money. Based on a debt service model that forecasts operating results for BAM through maturity of the surplus notes, the present value of the BAM surplus notes, including accrued interest and using an 8% discount rate, was estimated to be $91 million, $93 million, $98 million and $114 million less than the nominal GAAP carrying values as of December 31, 2023, September 30, 2023, December 31, 2022 and September 30, 2022, respectively.

White Mountains believes these adjustments are useful to management and investors in analyzing the intrinsic value of HG Global, including the value of the in-force business at HG Re, HG Global’s reinsurance subsidiary, and the value of the BAM surplus notes.

The denominator used in the calculation of adjusted book value per share equals the number of common shares outstanding adjusted to exclude unearned restricted common shares, the compensation cost of which, at the date of calculation, has yet to be amortized. Restricted common shares are earned on a straight-line basis over their vesting periods. The reconciliation of GAAP book value per share to adjusted book value per share is included on page 7.

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 excludes interest expense on debt, income tax (expense) benefit, depreciation and amortization of other intangible assets from 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 excluded from EBITDA. The adjustments 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 adjustment 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.
20


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.

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 18 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.

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.
