AM Best Places Aspen Ratings Under Review
AM Best has placed under review with positive implications the Financial Strength Ratings of A [Excellent] and the Long-Term Issuer Credit Ratings [Long-Term ICR] of “a” [Excellent] of Aspen Insurance UK Limited [AIUK] [United Kingdom], Aspen Bermuda Limited [ABL] [Bermuda], Aspen American Insurance Company [AAIC] [Austin, TX] and Aspen Specialty Insurance Company [ASIC] [Bismarck, ND].
Concurrently, AM Best has placed under review with positive implications the Long-Term ICR of “bbb” [Good] of Aspen Insurance Holdings Limited [Aspen] [Bermuda], a non-operating holding company, along with the Long-Term Issue Credit Ratings [Long-Term IR] on the preference shares of Aspen and the indicative Long-Term IRs under the company’s universal shelf registration. [Please see below for a detailed listing of the Long-Term IRs.]
The ratings agency said, “The ratings have been placed under review with positive implications following the announcement on 27 August 2025 that SOMPO Holdings, Inc., a wholly owned subsidiary, has entered into a definitive merger agreement pursuant to which it will acquire 100% of the issued Class A ordinary shares of Aspen for a consideration of approximately USD 3.5 billion. The transaction remains subject to regulatory approval.
“The under review with positive implications status reflects the potential financial and operation benefits that Aspen may derive from being part of a significantly larger insurance organisation, which is of greater financial strength. The ratings will remain under review pending completion of the transaction and a detailed review by AM Best of Aspen’s future business plans.”
