Management Comments

• Results in the first quarter of 2026 were driven primarily by solid results from White Mountains' operating businesses that were more than offset by a decline in the MediaAlpha share price.
• Ark's earned premiums increased 7% in the first quarter of 2026 compared to the first quarter of 2025, driven primarily by continued growth in the specialty and property lines of business.
• Excluding MediaAlpha, investment results in the first quarter of 2026 were driven primarily by net investment income, net unrealized investment gains from other long-term investments and net unrealized investment losses from the fixed income and common equity portfolios.

Industry Context

StockSavvy.ai notes that the insurance and asset management sectors are sensitive to interest rate movements and geopolitical events, as evidenced by White Mountains' results. The company's diversified segments provide some resilience, but the significant impact of MediaAlpha's performance highlights the volatility in certain investment holdings.

Comparison to Industry Standards

• White Mountains' fixed income portfolio returned 0.5% in Q1 2026, underperforming the Bloomberg Intermediate U.S. Aggregate Index return of 0.1%.
• The company's common equity securities portfolio returned -4.4% in Q1 2026, underperforming the S&P 500 Index return of -4.3%.

Stakeholder Impact

• Shareholders experienced a decrease in book value per share and a net loss for the quarter.
• The company's ability to generate future returns is influenced by investment performance, particularly in MediaAlpha, and the management of insurance risks.
• The company's credit facilities and debt instruments contain covenants that require ongoing compliance.

Next Steps

• Continue to monitor the performance of the MediaAlpha investment.
• Manage catastrophe losses and prior year reserve development within the Ark/WM Outrigger segment.
• Execute on new acquisitions for WTM Partners, including BaseSix Systems LLC and Hawkeye Electric, LLC.

Key Dates

Recommendation

While the company experienced a net loss and a decline in book value per share, driven by investment performance and catastrophe losses, the underlying operating businesses show resilience and improvement in combined ratios. The company maintains a strong liquidity position and has undrawn credit facilities. However, the significant negative impact from the MediaAlpha investment and ongoing geopolitical risks warrant a cautious 'hold' stance until performance stabilizes and the impact of these factors becomes clearer.
