Quarterly Highlights and Segment Performance
For the quarter, Hamilton reported operating EPS of $1.55, which was 46.2% ahead of analyst expectations for non-GAAP EPS with top-line gains seen across both the International and Bermuda segments. The company’s annualized return on average equity reached 30.2%, an improvement of 6.6 percentage points from the prior year period, reflecting strong profitability and capital management.
Gross premiums written (GAAP) increased to $712.0 million, up 18% from the related period last year. The International Segment contributed $344.8 million in gross premiums written, a 10.6% increase while the Bermuda Segment grew faster, adding $367.2 million in gross premiums written, up 25.9%. Net premiums earned (GAAP) rose 22.1% overall, supported by new casualty and specialty reinsurance business, especially in Bermuda.
The International Segment posted net premiums earned of $253.2 million and delivered an underwriting income of $27.1 million. The combined ratio—a key insurance industry measure that compares claims and expenses to premiums, with numbers below 100% typically indicating underwriting profitability—improved to 89.3% from 91.0% in Q2 2024. Conversely, Bermuda’s underwriting income was $40.3 million, with its combined ratio increasing to 84.3%. The Bermuda result reflected more exposure to casualty reinsurance, which drove an increase in both loss and acquisition expense ratios. Across the company, the consolidated combined ratio edged up to 86.8%, compared to 84.4% in Q2 2024, pointing to the impact of business mix changes and a modest rise in underlying costs.
Investment income continued to play a crucial role in boosting bottom-line results. Net investment income came in at $148.7 million, with the Two Sigma Hamilton Fund delivering $87.1 million and traditional fixed income, short-term, and cash investments adding $61.6 million. This performance reflects effective diversification and continued momentum in both managed and market-based investment assets. Share buybacks also featured, with $35.0 million of shares repurchased.
Look Ahead and Management Guidance
Hamilton management did not provide updated or explicit quantitative financial guidance for the next quarter or for the remaining fiscal year. The leadership affirmed a focus on maintaining double-digit top-line growth and continuing share repurchases if capital conditions permit, but did not release clear targets for EPS or revenue.
Recent trends suggest that investors should monitor shifts in Hamilton’s loss and acquisition cost ratios, especially as business grows in higher-risk areas such as casualty and specialty reinsurance. Increased catastrophe losses in Q1 2025 and changes in business mix create potential for volatility in future quarters. HG does not currently pay a dividend.
