Hamilton Insurance Delivers Record Earnings, Signals Disciplined Growth

Hamilton Insurance Group, Ltd. Class B ((HG)) has held its Q4 earnings call. Read on for the main highlights of the call.

Hamilton Insurance Group, Ltd. Class B’s latest earnings call struck a distinctly upbeat tone, with management highlighting record profits, double‑digit premium growth, stronger underwriting results, and standout investment performance. Executives acknowledged pressures from higher attritional and large‑loss activity, but stressed disciplined underwriting, capital strength, and a willingness to sacrifice growth where pricing no longer meets return hurdles.

Record Net Income and Elevated Returns on Equity

Hamilton reported record 2025 net income of $577 million, a 44% jump from $400 million in 2024, underscoring substantial earnings momentum. Full‑year return on average equity climbed to 22%, while fourth‑quarter net income of $172 million translated into an impressive 25% annualized ROAE, signaling efficient use of shareholder capital.

Top-Line Expansion Driven by Both Core Platforms

Gross premiums written rose 21% for 2025 to $2.9 billion, with fourth‑quarter growth of 23%, confirming strong demand across the franchise. Bermuda premiums advanced 26% to $1.4 billion and International grew 16% to $1.5 billion, illustrating balanced expansion and diversified sources of revenue.

Improved Combined Ratio and Underwriting Profitability

The full‑year combined ratio improved to 92.9%, showing enhanced underwriting profitability despite a more competitive market backdrop. Fourth‑quarter underwriting income surged to $76 million versus $22 million a year earlier, with the Q4 combined ratio strengthening to 87% from 95.4% in 2024.

Lower Catastrophe Losses Support Better Loss Ratio

The Q4 loss ratio fell to 54.6%, down 5.5 points from the prior‑year period, helped mainly by meaningfully lower net catastrophe losses. Cat losses improved by roughly 9 points versus 2024, allowing Hamilton to post stronger margins even as it absorbed higher attritional losses and business‑mix shifts.

Book Value Growth and Balance Sheet Strength

Shareholders’ equity increased 21% year over year to $2.8 billion, highlighting robust capital generation over the period. Book value per share rose 24% to $28.50, and management pointed to roughly 25% tangible book value growth since the IPO and over the last year, reinforcing the firm’s capital strength.

Robust Investment Income and Fund Performance

Net investment income in Q4 reached $98 million, nearly triple the $36 million reported in 2024, providing a powerful earnings tailwind. The Two Sigma Hamilton Fund delivered $56 million of Q4 income and a 16% net return, or $310 million, for 2025, while fixed income added $38 million in the quarter with a new‑money yield of 4.2%.

Capital Returns Underscore Shareholder-Friendly stance

The board authorized a $2.00 per‑share special dividend, returning about $206 million of capital directly to investors and signaling confidence in future earnings power. Hamilton also repurchased $93 million of stock in 2025 at an average price of $22.13, leaving $178 million of remaining authorization for further buybacks.

Tax Credits and Favorable One-Time Tax Items

Management highlighted a Bermuda substance‑based tax credit of $20.7 million for 2025, which offset expenses in both Bermuda and corporate segments, providing a tailwind to net income. In addition, the company recognized a $28 million tax benefit from the release of valuation allowances, temporarily enhancing earnings.

Disciplined Cycle Management and Diversification Strategy

Executives emphasized disciplined cycle management, choosing to grow in attractive niches such as casualty reinsurance, specialty lines, and E&S casualty while avoiding underpriced risks. Hamilton has been trimming participation in large property accounts where competition has eroded pricing, focusing instead on sustainable profitability across its diversified platform.

Rising Attritional Losses and Larger Loss Events

The full‑year attritional loss ratio moved up to 54.4% from 53.1% in 2024, reflecting both larger loss activity and a shift in business mix toward casualty reinsurance. In Q4, attritional losses climbed further to 56.5% versus 51.2% a year earlier, with management citing elevated large losses in the quarter, including a sizeable satellite loss in specialty.

Bermuda Segment Faces Margin Pressure

Bermuda’s full‑year combined ratio deteriorated to 90.9% from 87.0% in 2024, as the business absorbed more large losses and moved more heavily into casualty reinsurance. The Bermuda current‑year attritional loss ratio in Q4 rose by 5 points to 56.7%, confirming that the higher‑loss‑ratio casualty mix is weighing on segment‑level margins.

Competitive Property Market and Pricing Headwinds

At the January 1 renewals, management described abundant capacity and intense competition in global property catastrophe, with headline pricing down. In response, Hamilton cut its participations on large property D&F accounts where pricing fell below return thresholds, indicating fewer growth opportunities and a cautious stance in this segment.

International Segment Expenses and Mix Challenges

In the International segment, the Q4 expense ratio rose to 42%, up 1.4 points, largely due to reduced ceding commissions, higher profit commissions, and lower third‑party fee income. Current‑year attritional losses for International were also higher in the quarter, reflecting large‑loss activity and adding pressure to segment profitability.

Redefined Attritional Loss Threshold Complicates Comparisons

Hamilton raised its catastrophe and headline‑loss threshold from $5 million to $10 million starting in 2026, shifting more events into the attritional loss bucket. As a result, reported attritional loss ratio guidance moves to roughly 55% at the group level, with around 56% for Bermuda and 54.5% for International, making year‑over‑year comparisons more complex.

Growth Expected to Slow as Market Transitions

Management signaled that the market is shifting toward a more competitive phase, which will limit the ability to sustain recent double‑digit growth rates. While attractive niches remain, Hamilton expects growth to become more measured and selective, prioritizing margin protection and underwriting discipline over pure top‑line expansion.

Forward-Looking Guidance and Capital Allocation Plans

For 2026, Hamilton guided to a group attritional loss ratio near 55% with catastrophe losses around 6–7%, alongside continued improvement in other underwriting expense ratios and corporate costs of $45–50 million. The company expects no value‑appreciation‑pool expense, anticipates about $27 million in Bermuda tax credits under the phase‑in, and plans to continue active capital returns through the special dividend and remaining buyback capacity.

Hamilton’s earnings call presented a company enjoying record profitability and strong investment gains while staying realistic about rising loss costs and a more competitive market. For investors, the key takeaway is a management team focused on disciplined underwriting, careful capital deployment, and protecting returns, even if that means moderating growth in the years ahead.
