Hamilton Reports $400 million of Net Income, 23.5% Growth in Book Value, and Return on Average Equity of 18.3% in 2024
PEMBROKE, Bermuda, February 26, 2025 – Hamilton Insurance Group, Ltd. (NYSE: HG; “Hamilton” or the “Company”) today announced financial results for the fourth quarter and full year ended December 31, 2024.
Commenting on the results, Pina Albo, CEO of Hamilton, said:
“2024 was an exceptional year for Hamilton. In our first full year as a public company, our overall financial results were excellent, with strong contributions from both underwriting and investments. Our net income was $400 million, a 55% increase over prior year, and our book value per common share increased 23.5%.
Hamilton’s combined ratio of 91.3%, in a year with significant large loss activity, demonstrated the benefits of our business diversification and our sharp focus on underwriting discipline. We achieved this result while also increasing our gross premiums written by 24%, leaning into favorable market conditions.
Our investment portfolio produced $362 million in total returns, including a standout 16.3% return from the Two Sigma Hamilton Fund.
I am very proud of what we have achieved as a Group and excited about our business prospects going forward. The hard work our team has put in over the past few years and our unique culture have positioned Hamilton exceedingly well for the future.”

Non-GAAP Financial Measures Reconciliation
We present our results of operations in a way that we believe will be the most meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance. Some of the measurements are considered non-GAAP financial measures under SEC rules and regulations. In this press release, we present underwriting income (loss), a non-GAAP financial measure as defined in Item 10(e) of SEC Regulation S-K. We believe that non-GAAP financial measures, which may be defined and calculated differently by other companies, help explain and enhance the understanding of our results of operations. However, these measures should not be viewed as a substitute for those determined in accordance with U.S. GAAP. Where appropriate, reconciliations of our non-GAAP measures to the most comparable GAAP figures are included below.
Underwriting Income (Loss)
We calculate underwriting income (loss) on a pre-tax basis as net premiums earned less losses and loss adjustment expenses, acquisition costs and other underwriting expenses (net of third party fee income). We believe that this measure of our performance focuses on the core fundamental performance of the Company’s reportable segments in any given period and is not distorted by investment market conditions, corporate expense allocations or income tax effects.
The following table reconciles underwriting income (loss) to net income (loss), the most comparable GAAP financial measure:

| Three Months Ended |  | Years Ended
| December 31, |  | December 31,
($ in thousands) | 2024 |  | 2023 |  | 2024 |  | 2023
Underwriting income (loss) | $ | 22,444 |  |  | $ | 36,028 |  |  | $ | 149,364 |  |  | $ | 129,851 |
Total net realized and unrealized gains (losses) on investments and net investment income (loss) | 76,156 |  |  | 120,465 |  |  | 574,674 |  |  | 240,066 |
Other income (loss), excluding third party fee income | — |  |  | 312 |  |  | — |  |  | 397 |
Net foreign exchange gains (losses) | 6,652 |  |  | (2,230) |  |  | (3,231) |  |  | (6,185) |
Corporate expenses | (19,286) |  |  | (44,858) |  |  | (61,111) |  |  | (76,691) |
Amortization of intangible assets | (3,747) |  |  | (2,914) |  |  | (15,520) |  |  | (10,783) |
Interest expense | (5,526) |  |  | (5,428) |  |  | (22,616) |  |  | (21,434) |
Income tax (expense) benefit | (2,284) |  |  | 31,974 |  |  | (8,402) |  |  | 25,066 |
Net income (loss), prior to non-controlling interest | $ | 74,409 |  |  | $ | 133,349 |  |  | $ | 613,158 |  |  | $ | 280,287 |

Third Party Fee Income
Third party fee income includes income that is incremental and/or directly attributable to our underwriting operations. It is primarily comprised of fees earned by the International Segment for management services provided to third party syndicates and consortia and by the Bermuda Segment for performance based management fees generated by our third party capital manager, Ada Capital Management Limited. We believe that this measure is a relevant component of our underwriting income (loss).
The following table reconciles third party fee income to other income, the most comparable GAAP financial measure:

| Three Months Ended |  | Years Ended
| December 31, |  | December 31,
($ in thousands) | 2024 |  | 2023 |  | 2024 |  | 2023
Third party fee income | $ | 5,818 |  |  | $ | 10,480 |  |  | $ | 23,752 |  |  | $ | 18,234 |
Other income (loss), excluding third party fee income | — |  |  | 312 |  |  | — |  |  | 397 |
Other income (loss) | $ | 5,818 |  |  | $ | 10,792 |  |  | $ | 23,752 |  |  | $ | 18,631 |

Other Underwriting Expenses
Other underwriting expenses include those general and administrative expenses that are incremental and/or directly attributable to our underwriting operations. While this measure is presented in Note 9, Segment Reporting, in the audited consolidated financial statements, it is considered a non-GAAP financial measure when presented elsewhere.
Corporate expenses include holding company costs necessary to support our reportable segments. As these costs are not incremental and/or directly attributable to our underwriting operations, these costs are excluded from other underwriting expenses, and therefore, underwriting income (loss). General and administrative expenses, the most comparable GAAP financial measure to other underwriting expenses, also includes corporate expenses.
The following table reconciles other underwriting expenses to general and administrative expenses, the most comparable GAAP financial measure:

| Three Months Ended |  | Years Ended
| December 31, |  | December 31,
($ in thousands) | 2024 |  | 2023 |  | 2024 |  | 2023
Other underwriting expenses | $ | 69,674 |  |  | $ | 56,923 |  |  | $ | 210,013 |  |  | $ | 183,165 |
Corporate expenses | 19,286 |  |  | 44,858 |  |  | 61,111 |  |  | 76,691 |
General and administrative expenses | $ | 88,960 |  |  | $ | 101,781 |  |  | $ | 271,124 |  |  | $ | 259,856 |

Other Underwriting Expense Ratio
Other Underwriting Expense Ratio is a measure of the other underwriting expenses (net of third party fee income) incurred by the Company and is expressed as a percentage of net premiums earned.
Loss Ratio
Attritional Loss Ratio – current year is the attritional losses incurred by the company relating to the current year divided by net premiums earned.
Attritional Loss Ratio – prior year development is the attritional losses incurred by the company relating to prior years divided by net premiums earned.
Catastrophe Loss Ratio – current year is the catastrophe losses incurred by the company relating to the current year divided by net premiums earned.
Catastrophe Loss Ratio – prior year development is the catastrophe losses incurred by the company relating to prior years divided by net premiums earned.
Combined Ratio
Combined Ratio is a measure of our underwriting profitability and is expressed as the sum of the loss and loss adjustment expense ratio, acquisition cost ratio and other underwriting expense ratio. A combined ratio under 100% indicates an underwriting profit, while a combined ratio over 100% indicates an underwriting loss.
