Hamilton Insurance Group, Ltd.
Hamilton Insurance Group, Ltd. is a Bermuda exempted company, incorporated under the laws of Bermuda on 4 September 2013. Its registered office is Wellesley House North, 1st Floor, 90 Pitts Bay Road, Pembroke HM 08, Bermuda. Bermuda’s Registrar of Companies does not offer free public access to individual company registration numbers, and no registration number is disclosed in the US Securities and Exchange Commission (SEC) filings reviewed for this profile, so Hamilton Insurance Group, Ltd.’s Bermuda registration number could not be independently confirmed.
Hamilton Insurance Group, Ltd. is an SEC registrant (CIK 0001593275), and its Class B common shares have traded on the New York Stock Exchange under the ticker symbol HG since its initial public offering, which priced on 9 November 2023 and closed on 14 November 2023.
According to the company’s Form 10-K for the year ended 31 December 2025, Hamilton Insurance Group, Ltd. is the holding company for a specialty insurance and reinsurance group organised into two reportable segments. The Bermuda segment underwrites property, casualty and specialty reinsurance through Hamilton Re, Ltd., a Bermuda-registered Class 4 reinsurer, and Hamilton Re US. The International segment comprises the Hamilton Global Specialty platform — Lloyd’s Syndicate 4000, managed by Hamilton Managing Agency Limited, and Hamilton Insurance Designated Activity Company (Hamilton Insurance DAC) in Dublin — together with Hamilton Select Insurance Inc., a US excess-and-surplus-lines carrier. The group’s operations span Bermuda, London, Dublin and multiple locations across the United States.
For the year ended 31 December 2025, Hamilton Insurance Group, Ltd. reported consolidated gross premiums written of approximately US$2.9 billion, total assets of approximately US$9.6 billion, shareholders’ equity of approximately US$2.8 billion, a combined ratio of 92.9% and more than 600 full-time employees, according to its FY2025 Form 10-K.

Shareholders of Hamilton Insurance Group, Ltd.
Hamilton Insurance Group, Ltd. is listed on the New York Stock Exchange and, as an SEC registrant, discloses shareholder information through beneficial-ownership filings and its own Shareholders Agreement rather than a complete shareholder register. According to the company’s definitive proxy statement filed 24 March 2026 (record date 17 March 2026), three shareholder groups remained party to a Shareholders Agreement dated 14 November 2023, the date of the company’s initial public offering, which grants director-appointment rights to any party that, together with its affiliates, held at least 5% of Hamilton’s issued and outstanding common shares on that date: Sango Holdings (Sango Hoken Holdings, LLC), Hopkins Holdings, LLC, and the Magnitude Investor group (Magnitude Master Fund, Magnitude Institutional, Ltd., Magnitude Partners Master Fund, L.P. and Magnitude Insurance Master Fund, LLC). A fourth original signatory, the Blackstone Investor group, ceased to qualify after Hamilton Insurance Group, Ltd. repurchased 9,124,729 Class A common shares from Blackstone Alternative Solutions LLC affiliates on 10 May 2024. Sango Holdings converted 300,000 Class A common shares into Class B common shares on 9 December 2025, and Hopkins Holdings converted 200,000 Class A common shares into Class B common shares on 10 December 2025. The proxy statement identifies these parties by their contractual 5%-or-more status as at the Shareholders Agreement date rather than publishing a current percentage-ownership table; exact current percentage stakes for Sango Holdings, Hopkins Holdings and the Magnitude Investor group were not disclosed in the sources reviewed for this profile.
