AM Best Comments on Credit Ratings of ProAssurance Group Members and ProAssurance Corporation Following Announced Acquisition by The Doctors Company Insurance Group

OLDWICK, N.J.--(BUSINESS WIRE)-- AM Best has commented that the Financial Strength Rating of A (Excellent) and the Long-Term Issuer Credit Ratings of “a+” (Excellent) of the members of ProAssurance Group (ProAssurance) are unchanged following the March 19, 2025, announcement that all outstanding shares of ProAssurance Corporation (PRA) (NYSE: PRA) (Birmingham, AL) will be acquired by The Doctors Company Insurance Group (TDC Group). The outlook of ProAssurance’s Credit Ratings (ratings) is stable.

The ratings reflect ProAssurance’s balance sheet strength, which AM Best assesses as strongest, as well as its adequate operating performance, favorable business profile and appropriate enterprise risk management.

ProAssurance is the fourth-largest writer of medical professional liability (MPL) insurance in the United States (based on direct premiums written) while TDC Group is the second largest. PRA is publicly traded on the New York Stock Exchange and will be 100% owned by The Doctors Company, An Interinsurance Exchange, the lead member of TDC Group, following the conclusion of the transaction, which is expected to close within the first half of 2026 pending regulatory approval.

AM Best does not expect the transaction to have any material change to ProAssurance’s rating fundamentals at this time. Both ProAssurance and TDC Group maintain current Long-Term ICRs of “a+” (Excellent) with stable outlooks. Given the extended nature of the transaction, AM Best will continue to evaluate each of these organizations independently while monitoring the progress and the effects of this transaction over time. As more detailed information becomes available, AM Best will reassess the ratings of both organizations taking into consideration the planned synergies and efficiencies gained from the transaction.
