//BestWire// - AM Best has maintained the under review with positive implications status for the Financial Strength Rating of A (Excellent) and the Long-Term Issuer Credit Rating of “a” (Excellent) of Aspen Insurance UK Limited (United Kingdom), Aspen Bermuda Limited (Bermuda), Aspen American Insurance Company (Austin, TX) and Aspen Specialty Insurance Company (Bismarck, ND). Concurrently, AM Best has maintained under review with positive implications for 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 IRs) 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.)
These Credit Ratings (ratings) remain under review with positive implications following the announcement on 24 February 2026 that Sompo Holding, Inc. (Sompo), via a wholly owned subsidiary, has completed the acquisition of 100% of the issued Class A ordinary shares of Aspen.
The under review with positive implications status reflects the potential financial and operational benefits that Aspen and its subsidiaries may derive from being part of a significantly larger insurance organisation, which is of greater financial strength. The ratings will remain under review pending a detailed review by AM Best of Sompo's future business plans for the Aspen entities.
The following Long-Term IRs have been maintained under review with positive implications:
Aspen Insurance Holdings Limited—
- “bb+” (Fair) on USD 250 million 5.625% perpetual non-cumulative preference shares
- “bb+” (Fair) on USD 250 million 5.625% perpetual non-cumulative preference shares
The following indicative Long-Term IRs under the universal shelf registration have been maintained under review with positive implications:
