Risks

• Softening market conditions in property lines affecting Ark/WM Outrigger's gross written premiums.
• Tighter municipal bond spreads impacting HG Global's demand for municipal bond insurance.
• Potential for future downgrades in credit ratings could increase borrowing costs.
• Reliance on investment returns, which are subject to market volatility and interest rate fluctuations.

Future Outlook

The company expects continued solid operating company results and investment returns. However, market conditions in property lines and the impact of geopolitical events like the war in Iran present ongoing challenges for the Ark/WM Outrigger segment. HG Global faces headwinds from tighter municipal bond spreads. The company anticipates meeting its capital requirements and has flexibility for external financing.

Management Comments

• White Mountains reported book value per share of $2,258 as of June 30, 2026, an increase of 4% in the second quarter of 2026 and 3% in the first six months of 2026, including dividends.
• Results in the second quarter and first six months of 2026 were driven primarily by strong operating company results and solid investment returns.
• The decline in gross written premiums in the second quarter of 2026 was driven primarily by softening market conditions in property lines, which was partially offset by growth in specialty lines.
• The increase in net realized and unrealized investment gains in the second quarter and first six months of 2026 were driven by increases in the fair value of Kudus participation contracts, primarily due to lower discount rates across the portfolio and step-ups in valuation related to certain sale transactions.

Key Dates

Recommendation

The company demonstrates solid operational performance and investment returns, with positive growth in book value. However, the impact of geopolitical events on the Ark segment, market headwinds for HG Global, and underperformance of common equity securities relative to the S&P 500 suggest a 'hold' rating. The company's diversified model and share repurchases are positive, but the noted risks warrant a cautious approach.
