MediaAlpha

During the second quarter of 2023, White Mountains completed a tender offer to purchase 5.9 million additional shares of MediaAlpha at a purchase price of $10.00 per share. As of June 30, 2023, White Mountains owns 22.9 million shares of MediaAlpha, representing a 36% basic ownership interest (33% on a fully-diluted/fully-converted basis). As of June 30, 2023, MediaAlpha's closing price was $10.31 per share, which decreased from $14.98 per share at March 31, 2023. The carrying value of White Mountains's investment in MediaAlpha was $236 million as of June 30, 2023 compared to $254 million at March 31, 2023. The $18 million decline in MediaAlpha's carrying value included $79 million of mark-to-market losses attributable to the 16.9 million shares of MediaAlpha owned by White Mountains as of March 31, 2023, partially offset by a $59 million increase in the carrying value attributable to the shares acquired in the tender offer and $2 million of mark-to-market gains attributable to the newly acquired shares. 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 $9.00 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 second quarter earnings release and related shareholder letter, which is available on MediaAlpha's investor relations website at www.investors.mediaalpha.com.

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 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 $95 million, $96 million $98 million and $120 million less than the nominal GAAP carrying values as of June 30, 2023, March 31, 2023, December 31, 2022 and June 30, 2022, respectively.

The value of HG Global's unearned premium reserve, net of deferred acquisition costs, was $182 million, $179 million, $179 million and $164 million as of June 30, 2023, March 31, 2023, December 31, 2022 and June 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 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 7.
The reduction in adjusted book value per share from the decline in MediaAlpha's share price on page 1 is a non-GAAP financial measure. White Mountains believes this measure to be useful to management and investors by showing the impact of changes in MediaAlpha's share price to White Mountains's adjusted book value per share. The following table presents the reconciliation from GAAP to the reported percentage:

($ in millions)	Book value per share	Adjustments to book value per share ⁽¹⁾	Adjusted book value per share
Balance as of March 31, 2023	$ 3,902.4	$ 80.5	$ 3,982.9
Unrealized investment losses from White Mountains's investment in MediaAlpha in the second quarter of 2023	$ 77.3		$ 77.3
Reduction in book value per share and adjusted book value per share from decline in MediaAlpha's share price	2 %		2 %


⁽¹⁾	See reconciliation 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.

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. The following tables present reconciliations from GAAP to the reported percentages:

	Three Months Ended June 30,		Six Months Ended June 30,

These statements are based on certain assumptions and analyses made by White Mountains in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors believed to be appropriate in the circumstances. 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:

the risks that are described from time to time in White Mountains's filings with the Securities and Exchange Commission, including but not limited to White Mountains's Annual Report on Form 10-K for the fiscal year ended December 31, 2022;
claims arising from catastrophic events, such as hurricanes, windstorms, earthquakes, floods, wildfires, tornadoes, tsunamis, severe winter weather, public health crises, terrorist attacks, war and war-like actions, explosions, infrastructure failures or cyber-attacks;
recorded loss reserves subsequently proving to have been inadequate;
the market value of White Mountains's investment in MediaAlpha;
the trends and uncertainties from the COVID-19 pandemic, including judicial interpretations on the extent of insurance coverage provided by insurers for COVID-19 pandemic related claims;
business opportunities (or lack thereof) that may be presented to it and pursued;
actions taken by rating agencies, such as financial strength or credit ratings downgrades or placing ratings on negative watch;
the continued availability of capital and financing;
deterioration of general economic, market or business conditions, including due to outbreaks of contagious disease (including the COVID-19 pandemic) and corresponding mitigation efforts;
competitive forces, including the conduct of other insurers;
changes in domestic or foreign laws or regulations, or their interpretation, applicable to White Mountains, its competitors or its customers; and
other factors, most of which are beyond White Mountains's control.

Consequently, all of the forward-looking statements made in this earnings release are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations. White Mountains assumes no obligation to publicly update any such forward-looking statements, whether as a result of new information, future events or otherwise.
