A casualty reinsurance sidecar is a separate investment vehicle set up to take on a slice of an insurer’s liability risks—like lawsuits, product claims, or bodily injury—in exchange for a share of premiums and potential losses. Think of it as a temporary partner that agrees to pay part of the bills if claims happen; for investors it offers a way to earn insurance-like returns that can be higher but come with clear exposure to claim events, affecting portfolio risk and insurer capital.
underwriting capacityfinancial
The amount of securities and risk an investment bank or syndicate is able and willing to guarantee for a new offering or underwriting deal. Think of it like the financial muscle behind a concert promoter: higher capacity means the underwriter can buy and absorb more shares if demand falls, which gives issuers confidence their sale will succeed and helps investors assess the likelihood of a well-managed, fully funded offering.
third-party capitalfinancial
Money provided to a company by outside investors, lenders, or funds that are not part of the company’s own owners or management. Like borrowing or taking on an outside partner to pay for a project or expansion, third-party capital can speed growth but may bring costs such as interest, fees, or demands for ownership and control; investors watch it because it affects a company’s risk, future profits, and share value.
collateralizedfinancial
Collateralized means a loan or financial obligation is backed by specific assets that the borrower pledges as security; if the borrower fails to pay, the lender can take those assets to recover losses. For investors, collateralization lowers the risk of loss and often leads to lower interest costs, but the value and liquidity of the pledged assets matter because weak or hard-to-sell collateral can still leave investors exposed.
retrocessional coveragefinancial
Retrocessional coverage is insurance that a reinsurer buys to protect itself from large losses — essentially “insurance for the insurer.” It transfers part of a reinsurer’s risk to another firm so a single catastrophe or big claim does not overwhelm one balance sheet. For investors, the presence and terms of retrocessional coverage affect how much risk a reinsurer keeps, which influences earnings stability, capital needs and the potential size of future losses.
structuring agentfinancial
A structuring agent is the firm or professional who designs and assembles complex financial products—such as securitizations or structured notes—by choosing the pieces, setting terms and coordinating legal, accounting and underwriting work. Think of them as the architect and project manager for a financial package; their choices determine how cash flows, risk and fees are split, which directly affects the product’s credit profile, pricing and transparency for investors.
placement agentfinancial
A placement agent is a professional or firm that helps organizations raise money from investors, such as individuals, institutions, or funds. They act like matchmakers, connecting those seeking investments with the right investors and guiding the process to ensure successful funding. For investors, they can provide access to exclusive opportunities and help navigate complex fundraising efforts.
PEMBROKE, Bermuda--(BUSINESS WIRE)--
Hamilton Insurance Group, Ltd. (NYSE: HG) (“Hamilton” or the “Company”) today announced it has established a casualty reinsurance sidecar to provide dedicated underwriting capacity in support of the Company’s casualty reinsurance portfolio.
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.
