**ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION.** 

On February 7, 2023, White Mountains Insurance Group, Ltd. issued a press release announcing its results for the three months and year ended December 31, 2022. 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 12 non-GAAP financial measures: (i) adjusted book value per share, (ii) Ark's adjusted loss and loss adjustment expense ratio, (iii) Ark's adjusted insurance acquisition expense ratio, (iv) Ark's adjusted other underwriting expense ratio, (v) Ark's adjusted combined ratio, (vi) Kudu's EBITDA, (vii) Kudu's adjusted EBITDA, (viii) Kudu's annualized adjusted EBITDA, (ix) Kudu's annualized revenue, (x) Kudu's cash revenue yield, (xi) total consolidated portfolio return excluding MediaAlpha and (xii) 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 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 and (ii) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. 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 $98 million, $114 million, $130 million and $132 million less than the nominal GAAP carrying values as of December 31, 2022, September 30, 2022, December 31, 2021 and September 30, 2021, respectively. The value of HG Global's unearned premium reserve, net of deferred acquisition costs, was $179 million, $172 million, $159 million and $154 million as of December 31, 2022, September 30, 2022, December 31, 2021 and September 30, 2021, 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 BAM surplus notes and the value of the in-force business at HG Re, HG Global's reinsurance subsidiary. 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 8 of Exhibit 99.1 to this Form 8-K.

Ark's adjusted loss and loss adjustment expense ratio, adjusted insurance acquisition expense ratio, adjusted other underwriting expense ratio and adjusted combined ratio are non-GAAP financial measures, which are derived by adjusting the GAAP ratios to add back the impact of whole-account quota-share reinsurance arrangements attributable to third-party capital providers for Ark's Lloyd's syndicates. The impact of these reinsurance arrangements relates to years of account prior to White Mountains's transaction with Ark. White Mountains believes these adjustments are useful to management and investors in evaluating Ark's results on a fully aligned basis (i.e., 100% of the syndicates' results). The reconciliation from the GAAP ratios to the adjusted ratios is included on page 18 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Non-cash equity-based compensation expense* - Represents non-cash expenses related to Kudu's management compensation that are settled with equity units in Kudu.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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 20 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.

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:

**WHITE MOUNTAINS REPORTS FOURTH QUARTER RESULTS**

**HAMILTON, Bermuda** (February 7, 2023) - White Mountains Insurance Group, Ltd. (NYSE: WTM) reported book value per share of $1,457 and adjusted book value per share of $1,495 as of December 31, 2022. Book value per share and adjusted book value per share increased 1% and 2% in the fourth quarter of 2022. Book value per share and adjusted book value per share increased 24% and 26% in the year ended December 31, 2022, including dividends, driven primarily by the net gain from the sale of NSM.

Manning Rountree, CEO, commented, "We had a solid fourth quarter capping an excellent year. ABVPS was up 2% in the quarter and 26% for the full year. In the quarter, we had good results from our operating companies and positive returns in our investment portfolio. BAM produced $38 million of gross written premiums and member surplus contributions in the quarter, capping a record year. Ark produced strong underwriting results in both the quarter and the full year, while growing full-year gross written premiums 37%. Kudu grew the fair value of its continuing portfolio and closed two value-adding exit transactions in the quarter, capping a good all-around year. Our investment portfolio was up 2.1% in the quarter and down 1.6% for the full year, an excellent relative result. At year end, we successfully launched Outrigger Re, deploying $205 million of capital. We finished the year with roughly $900 million of undeployed capital."

Comprehensive income (loss) attributable to common shareholders was $40 million and $788 million in the fourth quarter and year ended December 31, 2022 compared to $34 million and $(273) million in the fourth quarter and year ended December 31, 2021. Results in the year ended December 31, 2022 were driven primarily by the net gain from the sale of NSM of $876 million recorded in the third quarter, which included the impact of compensation and other costs recorded in Other Operations. Results in the year ended December 31, 2021 were driven primarily by $380 million of net realized and unrealized investment losses from White Mountains's investment in MediaAlpha.

During the fourth quarter of 2022, White Mountains invested $205 million into Outrigger Re Ltd., a newly-formed Bermuda special purpose insurer that will provide reinsurance protection on a portion of Ark's Bermuda global property catastrophe portfolio written in calendar year 2023.

**<u>HG Global/BAM</u>**

BAM's gross written premiums and member surplus contributions (MSC) collected were $38 million and $147 million in the fourth quarter and year ended December 31, 2022 compared to $34 million and $118 million in the fourth quarter and year ended December 31, 2021. BAM insured municipal bonds with par value of $2.6 billion and $16.0 billion in the fourth quarter and year ended December 31, 2022 compared to $4.9 billion and $17.5 billion in the fourth quarter and year ended December 31, 2021. Total pricing was 148 and 91 basis points in the fourth quarter and year ended December 31, 2022 compared to 70 and 67 basis points in the fourth quarter and year ended December 31, 2021. BAM's total claims paying resources were $1,423 million at December 31, 2022 compared to $1,260 million at September 30, 2022 and $1,192 million at December 31, 2021. In the fourth quarter of 2022, BAM completed a reinsurance agreement with Fidus Re that increased BAM's claims paying resources by $150 million.

------

Seán McCarthy, CEO of BAM, said, "BAM had a good quarter, capping a strong year for gross written premiums and MSC. New-issue municipal bond sales were actually down 21% year over year due to the rising interest rate environment. On the other hand, increased uncertainty made insurance more attractive to issuers, and secondary market demand was robust, as institutional investors utilized insurance in a wide range of portfolio management strategies. Total pricing was up significantly period over period, for both the fourth quarter and the full year."

HG Global reported pre-tax income (loss) of $12 million and $(23) million in the fourth quarter and year ended December 31, 2022 compared to $5 million and $21 million in the fourth quarter and year ended December 31, 2021. The increase in HG Global's pre-tax income in the fourth quarter of 2022 compared to the fourth quarter of 2021 was driven primarily by net unrealized investment gains on the HG Global fixed income portfolio. The decrease in HG Global's pre-tax income (loss) in the year ended December 31, 2022 compared to the year ended December 31, 2021 was driven primarily by net unrealized investment losses on the HG Global fixed income portfolio.

White Mountains reported pre-tax loss related to BAM of $14 million and $112 million in the fourth quarter and year ended December 31, 2022 compared to $16 million and $63 million in the fourth quarter and year ended December 31, 2021. The decrease in BAM's pre-tax loss in the fourth quarter of 2022 compared to the fourth quarter of 2021 was driven primarily by net unrealized investment gains on the BAM fixed income portfolio, partially offset by an increase in general and administrative expenses. The increase in BAM's pre-tax loss in the year ended December 31, 2022 compared to the year ended December 31, 2021 was driven primarily by net unrealized investment losses on the BAM fixed income portfolio.

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 non-controlling interests.

**<u>Ark</u>**

Ark's GAAP combined ratio was 59% and 82% in the fourth quarter and year ended December 31, 2022 compared to 70% and 87% in the fourth quarter and year ended December 31, 2021. Ark's adjusted combined ratio, which adds back amounts attributable to third-party capital providers, was 57% and 81% in the fourth quarter and year ended December 31, 2022 compared to 67% and 85% in the fourth quarter and year ended December 31, 2021. The GAAP combined ratio in the fourth quarter and year ended December 31, 2022 included 11 points and six points of favorable prior year development compared to less than one point and three points in the fourth quarter and year ended December 31, 2021. The GAAP combined ratio for the year ended December 31, 2022 included 13 points of catastrophe losses compared to 10 points in the year ended December 31, 2021. Catastrophe losses for the year ended December 31, 2022 included $45 million related to events in the Ukraine and $44 million related to Hurricane Ian on a net basis after reinstatement premiums.

Ark reported gross written premiums of $200 million and $1,452 million, net written premiums of $189 million and $1,195 million and net earned premiums of $286 million and $1,043 million in the fourth quarter and year ended December 31, of 2022 compared to gross written premiums of $164 million and $1,059 million, net written premiums of $134 million and $859 million and net earned premiums of $202 million and $637 million in the fourth quarter and year ended December 31, 2021. Ark reported pre-tax income of $116 million and $95 million in the fourth quarter and year ended December 31, 2022 compared to $57 million and $53 million in fourth quarter and year ended December 31, 2021. Ark's results included net realized and unrealized investment gains (losses) of $21 million and $(55) million in the fourth quarter and year ended December 31, 2022 compared to $6 million and $17 million in the fourth quarter and year ended December 31, 2021. Ark's pre-tax income for the year ended December 31, 2021 also included $25 million of transaction expenses related to White Mountains's transaction with Ark.

------

Ian Beaton, CEO of Ark, said, "Ark had a strong finish to the year with a GAAP combined ratio of 59% in the fourth quarter, benefiting from light catastrophes and favorable reserve development. For the full year, Ark produced a GAAP combined ratio of 82%. Gross written premiums were $1.5 billion for the year, up 37% from 2021 with risk adjusted rate change of 9%. In December, AM Best completed its annual review and affirmed Ark's 'A/stable' rating. Ark had a solid start to 2023, exceeding $575 million of gross written premiums in January, with risk adjusted rate change of 15%."

**<u>Kudu</u>**

Kudu reported total revenues of $32 million, pre-tax income of $23 million and adjusted EBITDA of $9 million in the fourth quarter of 2022 compared to total revenues of $45 million, pre-tax income of $37 million and adjusted EBITDA of $14 million in the fourth quarter of 2021. Total revenues and pre-tax income in the fourth quarter of 2022 included $13 million of net investment income and $18 million of net realized and unrealized investment gains compared to $18 million and $27 million in the fourth quarter of 2021. Kudu's net investment income in the fourth quarter of 2022 reflected the impact of recent sale transactions and lower incentive fees, partially offset by new participation contracts acquired.

Kudu reported total revenues of $119 million, pre-tax income of $89 million and adjusted EBITDA of $42 million in the year ended December 31, 2022 compared to total revenues of $134 million, pre-tax income of $108 million and adjusted EBITDA of $33 million in the year ended December 31, 2021. Total revenues and pre-tax income in the year ended December 31, 2022 included $54 million of net investment income and $64 million of net realized and unrealized investment gains compared to $44 million and $90 million in the year ended December 31, 2021.

As of December 31, 2022, Kudu had deployed $713 million in 20 asset and wealth management firms globally, including two that have been exited. As of December 31, 2022, the asset and wealth management firms have combined assets under management of approximately $74 billion, spanning a range of asset classes. Kudu's capital was deployed at an average gross cash yield at inception of 9.9%.

Rob Jakacki, CEO of Kudu, said, "Kudu had a good fourth quarter, closing two value-adding sale transactions while growing the fair value of our continuing portfolio. Despite challenging financial market conditions, Kudu had a strong year, growing our business and improving our key metrics. For the full year, we grew net investment income to $54 million, up 23% year over year, and adjusted EBITDA to $42 million, up 27% year over year. During the year, we closed three new deployments. Our current portfolio is performing well, and our pipeline of new deployment opportunities is robust."

**<u>MediaAlpha</u>**

White Mountains owns 16.9 million shares of MediaAlpha, representing a 27% basic ownership interest (25% on a fully-diluted/fully-converted basis). As of December 31, 2022, the closing price was $9.95 per share, which increased from $8.75 per share at September 30, 2022. As of December 31, 2022, the value of White Mountains's investment in MediaAlpha was $169 million, which increased from $148 million at September 30, 2022. 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 $6.60 per share increase or decrease in White Mountains's book value per share and adjusted book value per share. We encourage you to read MediaAlpha's fourth quarter earnings release and related shareholder letter scheduled for February 23, 2023, which will be available on MediaAlpha's investor relations website at www.investors.mediaalpha.com.

------

**<u>Other Operations</u>**

White Mountains's Other Operations reported pre-tax loss of $8 million and $198 million in the fourth quarter and year ended December 31, 2022 compared to $52 million and $392 million in the fourth quarter and year ended December 31, 2021. Net realized and unrealized investment gains (losses) from White Mountains's investment in MediaAlpha were $20 million and $(93) million in the fourth quarter and year ended December 31, 2022 compared to $(55) million and $(380) million in the fourth quarter and year ended December 31, 2021. Excluding MediaAlpha, net realized and unrealized investment gains (losses) were $(4) million and $(2) million in the fourth quarter and year ended December 31, 2022 compared to $17 million and $51 million in the fourth quarter and year ended December 31, 2021. Net investment income was $19 million and $32 million in the fourth quarter and year ended December 31, 2022 compared to $2 million and $18 million in the fourth quarter and year ended December 31, 2021. The increase in net investment income in both the fourth quarter and year ended December 31, 2022 was driven primarily by the increase in invested assets resulting from the sale of NSM.

White Mountains's Other Operations reported general and administrative expenses of $50 million and $169 million in the fourth quarter and year ended December 31, 2022 compared to $26 million and $105 million in the fourth quarter and year ended December 31, 2021. The increases in general and administrative expenses in the fourth quarter and year ended December 31, 2022 compared to the fourth quarter and year ended December 31, 2021 were driven by higher incentive compensation costs and advisory fees, primarily in connection with the sale of NSM.

**<u>Share Repurchases</u>**

In the fourth quarter of 2022, White Mountains repurchased and retired 4,076 of its common shares for $5 million at an average share price of $1,298.11, or 87% of White Mountains's adjusted book value per share at December 31, 2022. In the year ended December 31, 2022, White Mountains repurchased and retired 461,256 of its common shares for $616 million at an average share price of $1,335.11, or 89% of White Mountains's adjusted book value per share at December 31, 2022.

In the fourth quarter of 2021, White Mountains repurchased and retired 11,999 of its common shares for $13 million at an average share price of $1,072.72, or 90% of White Mountains's adjusted book value per share at December 31, 2021. In the year ended December 31, 2021, White Mountains repurchased and retired 98,511 of its common shares for $108 million at an average share price of $1,091.29, or 92% of White Mountains's adjusted book value per share at December 31, 2021.

**<u>Regulation G</u>**

This earnings release includes non-GAAP financial measures that have been reconciled from their most comparable GAAP financial measures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 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 and (ii) to add back the unearned premium reserve, net of deferred acquisition costs, at HG Global.

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 $98 million, $114 million, $130 million and $132 million less than the nominal GAAP carrying values as of December 31, 2022, September 30, 2022, December 31, 2021 and September 30, 2021, respectively.

The value of HG Global's unearned premium reserve, net of deferred acquisition costs, was $179 million, $172 million, $159 million and $154 million as of December 31, 2022, September 30, 2022, December 31, 2021 and September 30, 2021, 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 BAM surplus notes and the value of the in-force business at HG Re, HG Global's reinsurance subsidiary.

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 8.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ark's adjusted loss and loss adjustment expense ratio, adjusted insurance acquisition expense ratio, adjusted other underwriting expense ratio and adjusted combined ratio are non-GAAP financial measures, which are derived by adjusting the GAAP ratios to add back the impact of whole-account quota-share reinsurance arrangements attributable to third-party capital providers for Ark's Lloyd's syndicates. The impact of these reinsurance arrangements relates to years of account prior to White Mountains's transaction with Ark. White Mountains believes these adjustments are useful to management and investors in evaluating Ark's results on a fully aligned basis (i.e., 100% of the syndicates' results). The reconciliation from the GAAP ratios to the adjusted ratios is included on page 18.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Non-cash equity-based compensation expense* - Represents non-cash expenses related to Kudu's management compensation that are settled with equity units in Kudu.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:
