Future Outlook

The acquisition of Distinguished Programs is expected to close in the third quarter of 2025.

A $2.0 million top-up tax is forecasted for the twelve months ended December 31, 2025, due to the OECD Pillar Two initiative. Management believes current cash balances, operational cash flows, and routine investment activities are sufficient to meet foreseeable cash requirements, and the company retains flexibility for external debt or equity financing.

Management Comments

• Book value per share of $1,804 as of June 30, 2025, an increase of 3% in both the second quarter and first six months of 2025, including dividends. Results in the second quarter and first six months of 2025 were driven primarily by sound results from White Mountains' operating businesses and good investment returns.
• Through June 30, 2025, WM Outrigger Re generated pre-tax income of $10 million from the 2025 underwriting year, $28 million from the 2024 underwriting year and $76 million from the 2023 underwriting year.
• Kudu deployed $69 million, including transaction costs, into one new asset management firm in 2025.
• Managed premiums were driven by growth in the renewal book as well as new business volume. Renewal book growth was driven by strong client policy retention rates as well as approved rate increases that went into effect in the first quarter of 2025.
• Bamboo also expanded its number of reinsurance partners.
• During the second quarter of 2025, White Mountains renewed the Bamboo CRV for the 2025 treaty year at a commitment of up to $10 million, down from $30 million in the prior year due to strong demand from third-party Capacity Providers.
• 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.
• Management believes that White Mountains' cash balances, cash flows from operations and routine sales and maturities of investments are adequate to meet expected cash requirements for the foreseeable future at both a holding company and insurance, reinsurance and other operating subsidiary level.

Industry Context

The company operates within the dynamic insurance and asset management industries, which are subject to various market conditions, regulatory changes, and competitive pressures. The municipal bond insurance market, where HG Global operates, has experienced increased volatility and uncertainty, driving demand for bond insurance. The global tax landscape is evolving with initiatives like the OECD Pillar Two, which introduces a global minimum tax regime impacting multinational enterprises. The insurance sector also faces ongoing challenges from catastrophic events and the need for robust reinsurance capacity.

Comparison to Industry Standards

• Ark's combined ratio of 84% in Q2 2025 and 90% in H1 2025 indicates strong underwriting performance, generally favorable compared to many P&C industry peers, even with catastrophe losses.
• Kudu's average gross cash yield at inception of approximately 9.5% on its deployments into asset management firms suggests attractive returns relative to typical private equity or debt investments.
• HG Global's increased total gross pricing to 206 basis points in Q2 2025 and 191 basis points in H1 2025 reflects successful pricing strategies in the municipal bond insurance market, potentially outperforming competitors in securing higher-priced issuances.
• Kudu's Loan-to-Value (LTV) Percentage of 22.2% as of June 30, 2025, is significantly below its 50% covenant, demonstrating conservative leverage and strong asset coverage compared to industry norms for credit facilities.
• Kudu's debt service coverage ratio of 2.8 times as of June 30, 2025, exceeds the minimum requirement of 2.5 times, indicating robust cash flow generation relative to debt obligations, a positive sign for creditors.
• Bamboo's total leverage ratio of 0.9 times as of June 30, 2025, is well below the maximum covenant of 4.5 times, suggesting a very healthy balance sheet and low financial risk for a P&C insurance distribution platform.
• The fixed income portfolio's performance of 1.5% in Q2 2025, outperforming the Bloomberg U.S. Intermediate Aggregate Index (0.5%), indicates effective management in a rising interest rate environment. However, its H1 2025 performance of 3.3% underperformed the index (4.2%), suggesting mixed results against benchmarks.
• The common equity securities portfolio's underperformance against the S&P 500 Index in Q2 2025 (4.5% vs. 10.9%) and H1 2024 (7.8% vs. 15.3%) is noted, primarily attributed to certain international listed equity funds employing a market-neutral strategy, which may deviate from broad market performance.
