Hamilton Q2 2026 Earnings: Catastrophe Losses Cut Underwriting Profit

Hamilton Insurance Group (NYSE: HG) reported Q2 2026 total revenue of $839.6 million, up approximately 13.3% from $740.8 million a year earlier, while diluted EPS fell to $1.42 from $1.79. Net premiums earned rose 14.6%, but $49.9 million of catastrophe losses pushed the combined ratio to 95.0% and reduced underwriting income by $38.3 million; investment returns helped support overall profitability.

Core Earnings Data

Premium growth remained broad, with gross premiums written rising 16.7% and net premiums earned increasing 14.6%. However, higher catastrophe losses and less favorable reserve development caused underwriting income and common-shareholder earnings to decline.

The combined ratio remained below 100%, meaning Hamilton still generated an underwriting profit, but it deteriorated by 8.2 percentage points from the prior-year quarter.

Business and Segment Performance

The International segment produced faster premium growth, but both operating segments reported lower underwriting income and higher combined ratios. International’s combined ratio moved close to 100%, while Bermuda remained more profitable on an underwriting basis despite greater deterioration from the prior year.

International growth was driven by new and existing casualty and specialty insurance business. The segment recorded $33.6 million of catastrophe losses from the Middle East conflict, although $13.8 million of favorable prior-year reserve development and a lower current-year attritional loss ratio provided partial offsets.

Bermuda’s growth came primarily from casualty and specialty reinsurance. Lower property reinsurance and insurance premiums partially offset that growth because of rate pressure. The segment also recorded $13.0 million of unfavorable attritional prior-year reserve development, mainly in certain casualty classes, and $16.2 million of catastrophe losses.

Profitability, Investments, and the Balance Sheet

Consolidated net income was $254.8 million, but $111.0 million was attributable to non-controlling interests, leaving $143.8 million attributable to common shareholders. This distinction is important because Hamilton’s Two Sigma investment structure creates a sizable difference between consolidated profit and the amount attributable to its shareholders.

Hamilton highlighted $141.3 million of net investment income, consisting of $115.5 million from the Two Sigma Hamilton Fund and $25.8 million from fixed-income securities, short-term investments, and cash. Separately, the statement of operations reported $252.3 million of total realized and unrealized investment gains plus net investment income before the allocation of overall profit to non-controlling interests.

At June 30, 2026, total cash and invested assets were $6.1 billion, compared with $5.9 billion at the end of 2025. Shareholders’ equity increased to $2.9 billion from $2.8 billion, while book value per share rose 1.4% to $28.91. Book value per share plus accumulated dividends reached $30.91, up 8.5% from December 31, 2025.

Hamilton repurchased $22.1 million of common shares during the quarter and $41.8 million during the first six months of 2026. The company also paid a $205.8 million special dividend in March 2026.

Catastrophe Losses Weakened Underwriting While Investments Supported Profit

The higher loss ratio explains most of the year-over-year deterioration in underwriting results. Hamilton’s loss and loss adjustment expense ratio rose 8.9 points to 61.7%. The current-year catastrophe loss ratio increased 5.9 points, while the prior-year catastrophe component increased another 2.3 points.

The Middle East conflict accounted for $45.7 million of Hamilton’s $49.9 million in catastrophe losses. The current-year attritional loss ratio also increased 0.3 points because of a changing business mix that included more casualty reinsurance.

Cost efficiencies provided only a partial offset. The other underwriting expense ratio declined 1.5 points, supported by Bermuda substance-based tax credits and a larger net premium base, but the acquisition cost ratio increased 0.8 points. As a result, premium growth did not translate into higher underwriting profit, although the investment portfolio provided substantial earnings support.

Recent Insider Transactions

The supplied six-month insider summary reports 753,153 shares classified as purchases across 31 transactions and 70,105 shares classified as sales across five transactions, resulting in net purchases of 683,048 shares. The latest detailed entries consisted of four sales and six stock awards, so the aggregate figures should not automatically be interpreted as open-market buying.

The detailed data did not provide share quantities for these ten transactions. The $0 values for the stock awards reflect the reported grant price and transaction value.

Risks Investors Need to Watch

• Catastrophe loss exposure: The Middle East conflict produced $45.7 million of losses and was the main reason the combined ratio increased. Further loss development could continue to affect underwriting profitability.
• Casualty mix and reserve development: Increased casualty reinsurance contributed to a higher attritional loss ratio, while Bermuda recorded $13.0 million of unfavorable prior-year attritional reserve development in the quarter.
• Property pricing pressure: Bermuda’s casualty and specialty growth was partially offset by lower property reinsurance and insurance premiums because of pressure on rates.
• Reliance on investment contribution: Investment returns provided significant support while underwriting income declined, making the relative contributions from underwriting and the Two Sigma Hamilton Fund important to monitor separately.

Summary

Hamilton generated double-digit premium growth in Q2 2026, led by the International segment, but catastrophe losses and Bermuda reserve pressure reduced underwriting income and common-shareholder earnings. The company remained profitable on an underwriting basis, while investment returns and a larger asset base supported overall results. The main issues to monitor are catastrophe loss development, casualty reserve trends, property pricing, and whether continued premium growth can produce better underwriting margins.
