WHITE MOUNTAINS REPORTS SECOND QUARTER RESULTS
WHITE MOUNTAINS INSURANCE GROUP LTD (WTM) filed an SEC Form 8-K — Results of Operations and Financial Condition. Exhibit 99.1 CONTACT: Rob Seelig (603) 640-2212 WHITE MOUNTAINS REPORTS SECOND QUARTER RESULTS HAMILTON, Bermuda (August 6, 2026) - White Mountains Insurance Group, Ltd. (NYSE: WTM) reported book value per share of $2,258 as of June 30, 2026, an increase of 4% for the second quar
How this was made
The 30-second read
Why it matters
Traders can update valuation and risk assumptions using the disclosed book value per share growth, repurchase amount, segment combined ratios, and quantified Ark losses related to the war in Iran, alongside investment mark-to-market effects (including MediaAlpha).
Market read
Fresh Q2 underwriting and capital allocation details (book value growth, buybacks, combined ratios) plus quantified catastrophe/war losses and investment mark-to-market impacts can drive near-term repricing of WTM’s risk-adjusted earnings power.
What to watch
Ark’s gross written premium decline (down 5% in the quarter) and the reliance on favorable prior-year development could reverse, and MediaAlpha mark-to-market gains may not be repeatable.
White Mountains Reports Second Quarter Results
Book value per share increased 4% in the second quarter, comprehensive income attributable to common shareholders was $199 million, and operating-company results included an 84% combined ratio at Ark/WM Outrigger. Results also reflected $151 million of net realized and unrealized investment gains, while Ark cited property-market softening and ongoing exposure to the war in Iran.

Management, verbatim
Book value per share was up 4% in the quarter, driven by strong operating company results and solid investment returns.
Liam Caffrey, CEO
Gross premiums were down 5% in the quarter driven by rate softening in property lines, which offset solid growth in specialty lines. The Iran war losses to date have been manageable but uncertainty remains.
Ian Beaton, CEO of Ark
We delivered a strong second quarter and start to the year, generating a 4% return in the quarter and a 15% return on a trailing 12 months basis.
Rob Jakacki, CEO of Kudu

AlphAI analysis generated from the company’s SEC earnings filing (Form 8-K Item 2.02, or Form 6-K for a foreign private issuer).

Background
SEC Form 8-K (Item 2.02) with Exhibit 99.1 reporting White Mountains’ second quarter 2026 results and financial condition, including book value per share, segment performance, and capital actions.
Ticker impact
White Mountains reports Q2 results, including 4% book value per share growth to $2,258 and $191M share repurchases, plus segment combined ratios.
Near-term bias modestly positive as traders price in book value growth and manageable catastrophe exposure, while monitoring investment-mark-to-market volatility.
This is a primary earnings-style disclosure with multiple concrete figures (book value, combined ratios, repurchases, MediaAlpha mark-to-market gains, and Ark Iran losses). However, the excerpt lacks full income statement and guidance, limiting conviction on forward earnings power.
Market effects
Reinsurance and specialty insurers may see read-across from Ark’s 84% combined ratio and quantified catastrophe/war exposure, plus commentary on rate softening in property lines.
Catastrophe-loss discussion references Iran war exposure and prior California wildfire losses, relevant to global catastrophe risk pricing.
Investment portfolio performance and mark-to-market gains (including MediaAlpha) highlight sensitivity to broader credit/equity markets affecting global insurers.
Counterpoint
Book value growth can be boosted by investment mark-to-market gains and dividends; underwriting profitability may be less favorable if catastrophe or rate softening worsens.
