Hamilton Insurance Group, Ltd. announced it has established a casualty reinsurance sidecar to provide dedicated underwriting capacity in support of the Company?s casualty reinsurance portfolio. 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 global investment firm and a premier strategic partner to insurance companies.

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.
