Risks

• Potential for increased losses from the ongoing war in Iran, which has already resulted in $25 million in estimated losses for Ark.
• The market value of White Mountains' investment in MediaAlpha is subject to significant fluctuations, with each $1.00 per share change impacting White Mountains' book value per share by approximately $7.00.
• Catastrophe losses, such as those related to the war in Iran and previously California wildfires, can significantly impact underwriting results.
• Deterioration of general economic, market, or business conditions could adversely affect results.
• Changes in domestic or foreign laws or regulations could impact the company.
• Competitive forces within the insurance and financial services industries.

Future Outlook

The company has deployed $125 million into Bishop Street Underwriters and announced two acquisitions by WTM Partners, with approximately $0.8 billion in undeployed capital. Forward-looking statements indicate expectations for future book value per share changes, business strategy, financial targets, and growth.

Management Comments

• "Book value per share ended the quarter at $2,170, down roughly 1% from year-end. Solid operating results were more than offset by a mark-to-market decline in our investment in MediaAlpha."
• "We are off to a good start in 2026, producing a combined ratio of 91% and gross written premiums of $1.1 billion. Market conditions continue to soften, but we still see opportunities to drive profitable growth, including through the addition of new teams and classes of business."
• "HG Global had a strong start to the year, with gross written premiums increasing 24% during the first quarter. The growth in written premiums was driven primarily by an increase in primary market activity and secondary market pricing."
• "Distinguished had a flattish quarter. Overall ScaleCo growth was muted, with strong premium growth in the environmental program offset by a decline in the umbrella program amid continued market pressure."
• "Excluding MediaAlpha, the total portfolio returned 1.0% in the quarter. Absolute and relative results were solid amid challenging financial markets."

Industry Context

StockSavvy.ai notes that White Mountains' Q1 2026 results reflect a challenging market environment, particularly for investment portfolios, as evidenced by the negative impact of MediaAlpha's share price decline. However, the company's diversified insurance and reinsurance segments, particularly Ark, show resilience with improved combined ratios, while growth initiatives in Kudu and Distinguished are progressing.

Comparison to Industry Standards

• The total consolidated investment portfolio return of 1.0% (excluding MediaAlpha) outperformed the benchmark Bloomberg Intermediate Aggregate Index (fixed income) return of 0.1% and the S&P 500 Index (equity) return of -4.3% for the first quarter of 2026.
• Ark's combined ratio of 91% in Q1 2026 is a strong performance within the P&C insurance and reinsurance sector, especially considering the impact of catastrophe losses.
• Kudu's 12% trailing 12-month return on equity is a solid metric within the asset management sector, though slightly down from the prior year.

Stakeholder Impact

• Shareholders: A 1% decrease in book value per share and a net loss for the quarter may negatively impact shareholder value and sentiment.
• Employees: Continued investment in talent and potential incentive compensation costs (as noted in Other Operations expenses) could impact employee morale and financial performance.
• Creditors: The company's debt levels across various segments remain significant, and ongoing performance will be monitored by creditors.

Next Steps

• Continue to monitor and manage investment portfolio performance, especially the MediaAlpha investment.
• Pursue growth opportunities within Kudu and Distinguished, including new programs and acquisitions.
• Manage catastrophe exposure and potential losses from ongoing geopolitical events.
• Integrate newly acquired entities, BaseSix Systems LLC and Hawkeye Electric, LLC.

Key Dates

Recommendation

The company shows resilience in its core insurance operations with strong combined ratios and growth in certain segments. However, the significant negative impact from investment performance, particularly the MediaAlpha holding, and the resulting decrease in book value per share warrant a cautious 'hold' stance until the investment outlook improves or the impact of these losses is better understood and mitigated.
