Management Comments

• Results in the third quarter were impacted by higher interest rates and a decline in the MediaAlpha share price, which led to unrealized losses that offset an otherwise solid quarter for operating results.
• Results in the first nine months of 2026 were driven by solid operating company results, partially offset by unrealized losses due to the impact of higher interest rates and a decline in the MediaAlpha share price.
• White Mountains believes that its non-GAAP financial measures are useful in evaluating its financial performance and condition.
• Management believes that White Mountains has the flexibility and capacity to obtain funds externally through debt or equity financing on both a short-term and long-term basis.

Industry Context

StockSavvy.ai notes that the insurance and asset management sectors are currently navigating a challenging environment characterized by rising interest rates, which impact investment valuations and can affect underwriting profitability. The geopolitical landscape also presents ongoing risks, particularly for property and casualty reinsurers with exposure to conflict zones.

Comparison to Industry Standards

• Arks combined ratio of 75.3% for Q3 2026 is strong and generally outperforms industry averages, which can often exceed 90-100% in challenging markets.
• The fixed income portfolio return of -0.7% in Q3 2026, while negative, reflects broader market trends where many fixed income portfolios experienced declines due to rising interest rates. The benchmark Bloomberg Intermediate U.S. Aggregate Index also saw a negative return of -2.6% for the same period.
• The performance of common equity securities and other long-term investments, returning 0.8% in Q3 2026, lagged behind the S&P 500 Index's 2.3% return, indicating potential underperformance in equity strategies or a more conservative allocation within those segments.
• The net investment income across segments reflects the benefit of higher interest rates on new investments and maturing assets, a trend observed across the financial services industry.

Legal Proceedings

• White Mountains, and the insurance industry in general, is routinely subject to claims related litigation and arbitration in the normal course of business, as well as litigation and arbitration that do not arise from, nor are directly related to, claims activity.
• White Mountains does not have any current non-claims related litigation that may have a material adverse effect on White Mountains' financial condition, results of operations or cash flows.

Related Party Transactions

• White Mountains has generally taken the fair value option for its equity method eligible investments, which are considered related parties.
• Kudu's Participation Contracts are generally noncontrolling equity interests in the form of revenue and earnings participation contracts.
• Distinguished's management compensation is settled with equity units in Distinguished.
• Intercompany transactions among White Mountains' segments have been eliminated in consolidation.

Stakeholder Impact

• Shareholders experienced a decrease in book value per share and a net loss for the quarter.
• Employees may be impacted by equity-based compensation plans tied to performance.
• Creditors are subject to debt covenants, with the company reporting compliance as of September 30, 2026.
• Insurance policyholders are covered by loss and loss adjustment expense reserves, with reinsurance in place to mitigate risk.

Next Steps

• Continue to monitor market conditions and adjust investment strategies accordingly.
• Manage ongoing exposure to geopolitical risks, such as the war in Iran.

Key Dates

Recommendation

While the company's core insurance operations remain solid with strong combined ratios and growth in certain segments, the net loss for the quarter and significant unrealized investment losses due to market conditions warrant a cautious approach. The impact of rising interest rates and geopolitical risks on investment portfolios and underwriting results creates uncertainty. The company's diversified business model and share repurchase activity are positive, but the current environment suggests a 'hold' rating until market conditions stabilize and investment performance improves.
