As part of Hamilton’s continued investment in its third-party capital offerings, it will draw upon the expertise of Tristan Latarche, who has been promoted to Senior Vice President of Hamilton ILS.

This sidecar will provide reinsurance capital over a multi-year period, with ceded premium over the duration of the structure projected to be approximately $300 million. The investor capital and overall asset strategy will be provided by Sixth Street, a leading global investment firm and a premier strategic partner to insurance companies.

As part of Hamilton’s continued investment in its third-party capital offerings, it will draw upon the expertise of Tristan Latarche, who has been promoted to Senior Vice President of Hamilton ILS, effective April 1, 2026, reporting to Tim Duffin, Group Chief Underwriting Officer. In this role, Latarche will lead the continued development and execution of Hamilton’s third-party capital strategy as the platform scales in size and sophistication.

“We are extremely pleased to announce that we have successfully established our first casualty reinsurance sidecar,” said Duffin. “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.”

“Tristan’s promotion further strengthens our leadership bench as we continue to develop our third-party capital capabilities over the long term.”

Latarche joined Hamilton as Vice President, Portfolio Manager in September 2024 to support Hamilton's third-party capital strategy. Prior to Hamilton, he held various underwriting and actuarial roles at Hiscox Re in London. Latarche is a Fellow of the Institute of Actuaries.

Hamilton will leverage its existing third-party capital platform Ada Re, Ltd. (“Ada Re”) for this offering. Ada Re has developed into a core component of Hamilton’s third-party capital strategy and serves as an increasingly meaningful contributor to Hamilton’s fee-based earnings. Ada Re also provides high-return collateralized property catastrophe reinsurance and retrocessional coverage that is distinct from, and complementary to, the Company’s Bermuda-based underwriting platform Hamilton Re’s balance sheet property reinsurance portfolio, together offering clients a broad range of solutions.

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