Hamilton Insurance Group, a Bermuda-based underwriting and insurance platform focused on specialty insurance and reinsurance, has established a reinsurance sidecar to support capacity within its casualty reinsurance portfolio.
The structure is expected to operate over multiple years, with total ceded premiums estimated at approximately $300 million across its lifespan. Investment capital and asset management responsibilities for the sidecar will be provided by Sixth Street, a global investment firm.
In connection with the development of its third-party capital capabilities, Hamilton has promoted Tristan Latarche to Senior Vice President of Hamilton ILS, effective April 1, 2026.
Reporting to Group Chief Underwriting Officer Tim Duffin, he will be responsible for advancing the firm’s third-party capital initiatives as the platform expands.
Latarche joined Hamilton in September 2024 as Vice President and Portfolio Manager and previously held underwriting and actuarial roles at Hiscox Re in London. He is a Fellow of the Institute of Actuaries.
The sidecar will be supported through Ada Re, Ltd., Hamilton’s existing third-party capital platform. Ada Re contributes to the group’s fee-based earnings and provides collateralised property catastrophe reinsurance and retrocessional coverage. Its offering is positioned to complement the property reinsurance portfolio written through Hamilton Re in Bermuda.
Aon Securities LLC acted as structuring and placement agent for the transaction. Legal advisers to Hamilton included Willkie Farr & Gallagher LLP and Carey Olsen Bermuda Limited.
“We are extremely pleased to announce that we have successfully established our first casualty reinsurance sidecar,” added 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.”
