AM Best Upgrades Credit Ratings of Columbia Mutual Insurance Company and Its Affiliates

AM Best has upgraded the Financial Strength Rating (FSR) to A (Excellent) from A- (Excellent) and the Long-Term Issuer Credit Ratings (Long-Term ICR) to “a” (Excellent) from “a-” (Excellent) of Columbia Mutual Insurance Company and its affiliates, collectively referred to as Columbia Insurance Group (Columbia). (See below for a detailed list of companies.) The outlook of these Credit Ratings (ratings) has been revised to stable from positive. All companies are headquartered in Columbia, MO.

The ratings reflect Columbia’s balance sheet strength, which AM Best assesses as very strong, as well as its adequate operating performance, neutral business profile and appropriate enterprise risk management (ERM).

The ratings upgrade reflects the revision in the operating performance building block assessment to adequate from marginal in response to sustained performance in key financial metrics that has resulted in a greater alignment with other adequately assessed peers. Results in recent years, as well as the first quarter of 2026, have benefited from enhanced pricing sophistication, refined underwriting appetite and management of catastrophe-prone exposures. The upgrade also reflects recent strategic initiatives, which have the potential to bring about long-term improvements in key operating performance metrics, helping to ensure continued alignment with the adequate assessment level.
