AM Best Comments on Credit Ratings of Starr International Company, Inc.’s Insurance Subsidiaries

AM Best has commented that the Financial Strength Rating (FSR) of A (Excellent) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of “a+” (Excellent) of the insurance subsidiaries of Starr International Company, Inc. (SICO) (Switzerland) remain unchanged following its announced acquisition of the IQUW group. The outlook of these Credit Ratings (ratings) is stable. These ratings apply to the members of Starr International Group (SIG) (New York, NY) and Starr Insurance & Reinsurance Limited (SIRL) (Bermuda), collectively referred to as Starr. (See below for a detailed listing of the companies and ratings.)

Starr announced on Oct. 29, 2025, that it has entered into a definitive agreement to acquire 100% of the IQUW group. The transaction is expected to close in the first half of 2026 and is subject to regulatory approvals and customary closing conditions. This acquisition expands Starr’s presence in the London wholesale market and bolsters its international business unit. While the final financial figures will be determined prior to close, AM Best has reviewed prospective financials and determined that Starr has ample liquidity and financial flexibility to support the transaction without impairing its balance sheet strength. Additionally, IQUW has been a strong performer in the past, which could aid Starr in future rating cycles, as synergies and scale are recognized within the greater group. AM Best will continue to monitor the transaction and respond if any of the initial indications change materially.

The FSR of A (Excellent) and the Long-Term ICRs of “a+” (Excellent) remain unchanged with stable outlooks for the following members of SIG:

• Starr Indemnity & Liability Company
• Starr Surplus Lines Insurance Company
• Starr Specialty Insurance Company

The FSR of A (Excellent) and the Long-Term ICRs of “a+” (Excellent) remain unchanged with stable outlooks for the following members of SIRL:
