Bucyrus, OH, April 16th, 2026 — Ohio Mutual Insurance Group today announced that it has reached an agreement to merge Gooding, Idaho-based Gem State Insurance as a subsidiary under Ohio Mutual Insurance Group’s mutual holding company structure, following unanimous votes by both organizations’ boards of directors.

Founded in 1910, Gem State currently serves nearly 13,000 policyholders across Idaho through a network of more than 60 independent agencies.

“Gem State is a well-respected mutual company with deep roots in its communities, and it aligns well with Ohio Mutual’s long-term vision and values,” said Mark C. Russell, Ohio Mutual President and CEO. “We’re looking forward to collaborating with the Gem State team and agent partners, and to adding Idaho as our ninth state of operation.”

The merger is still subject to approval by Gem State policyholders and insurance regulators in both Idaho and Ohio, and is expected to be completed in the third quarter of 2026. Plans are to continue to market products under the Gem State brand and to maintain its Idaho operations. Gem State will join Ohio Mutual’s intercompany pool: Ohio-domiciled Ohio Mutual Insurance Company, its wholly owned subsidiary United Ohio Insurance Company, Casco Indemnity Company, and United Mutual Insurance Company – all entities of holding company Ohio Mutual Insurance Group, Inc.

“Partnering with Ohio Mutual allows us to build on Gem State’s strong foundation, offer additional products, and expand our market share in Idaho while continuing to serve our policyholders and agent partners with the same focus and commitment,” said Gene Guilfoy, Gem State President and Board Chair.

“We share a mutual approach to business and a long-term view, and I’m confident this merger positions us well for a strong future,” added Adrian Celaya, Manager, Gem State.
