Ohio Mutual Insurance Group completed its merger with Idaho-based Gem State Insurance effective October 1, 2026. Gem State has been redomesticated to Ohio and is now part of Ohio Mutual’s mutual holding company structure. The Gem State name will remain in use, while Ohio Mutual says it plans to add products and member benefits for Idaho policyholders.
What the merger changes—and what it does not confirm
Ohio Mutual’s completion announcement says Gem State joined its family of companies alongside Ohio Mutual Insurance Company, United Ohio Insurance Company, Casco Indemnity Company, and United Mutual Insurance Company. The company says Gem State products will continue to be marketed under the Gem State Insurance name, with updated visual branding expected.
The announcement does not describe changes to individual policy contracts, coverage, premiums, billing, claims handling, or service contacts. Policyholders should not assume those terms changed—or stayed the same—based only on the merger announcement. For account-specific questions, check the current policy documents or contact the insurer or agent listed on them.
