Hamilton Insurance Group Launches New Casualty Reinsurance Sidecar

Hamilton Insurance Group, Ltd. has launched a casualty reinsurance sidecar, designed to provide dedicated underwriting capacity for its casualty reinsurance portfolio. This strategic initiative seeks to generate reinsurance capital over several years, with a projected ceded premium of approximately $300 million.

Investor capital is supplied by Sixth Street, an international investment firm and strategic insurance partner. Their collaboration enhances the asset strategy for the project, ensuring the sidecar's success and alignment with Hamilton's goals.

In related news, Hamilton has promoted Tristan Latarche to senior vice president of Hamilton ILS, effective April 1, 2026. Reporting to Tim Duffin, the group chief underwriting officer, Latarche will lead the advancement of Hamilton's third-party capital strategy. Since joining Hamilton in November 2024, Latarche has held roles in underwriting and actuarial analysis at Hiscox Re in London.

Tim Duffin commented on the venture, stating, "We are extremely pleased to announce that we have successfully established our first casualty reinsurance sidecar. This sidecar enhances our ability to support casualty reinsurance underwriting through scalable and efficient capital solutions, supports our disciplined growth strategy, and provides Hamilton with an additional source of fee income."

Hamilton's existing third-party capital platform, Ada Re, Ltd., significantly contributes to this initiative. The platform provides collateralized property catastrophe reinsurance and retrocessional coverage, complementing Hamilton Re's balance sheet property reinsurance portfolio.

For this transaction, Aon Securities LLC acted as the structuring and placement agent, while Willkie Farr & Gallagher LLP and Carey Olsen Bermuda Limited served as legal counsel for Hamilton.
