RetailFirst Insurance Group and its affiliate BusinessFirst Insurance Company are moving to Integrated Specialty Coverages as their managing general agency, ending a relationship with Summit Consulting that dates to BusinessFirst's founding in 2003 - and, in RetailFirst's case, to a workers' compensation operation that traces its origins to 1979. The change takes effect in the third quarter of 2026.
The timing carries a specific complication. ISC is itself mid-ownership transition: Onex Partners agreed in September 2025 to acquire the company from KKR, with the deal expected to close in the first half of 2026. It is not confirmed at the time of publication whether that closing has occurred. RetailFirst is making a long-term MGA commitment to a platform whose ownership structure may not yet be settled - a consideration that the announcement does not address directly.
Summit, based in Lakeland, Florida, and a member of Great American Insurance Group, manages six workers' compensation insurers including three Bridgefield companies and non-affiliate Retailers Casualty Insurance Company. The transition does not affect the business Summit manages for its Bridgefield-affiliated carriers.
The parties have entered a Transition Services Agreement to manage the handover. Summit will continue servicing all policies it underwrote for RetailFirst and BusinessFirst through their expiration, and will manage claims tied to those policies for three years after the transition period ends - a structured exit that protects policyholders through the change regardless of the commercial relationship ending.
RetailFirst and BusinessFirst together insure more than 11,500 businesses across Florida, Georgia, Indiana, Kentucky, North Carolina, South Carolina, Tennessee and Virginia. Both carriers carry an A- rating from AM Best.
ISC has grown into a platform supporting roughly 8,000 appointed agencies and more than 40 programs, built on AI-driven underwriting and its ISCx Marketplace. In January 2026 the company agreed to acquire Ohio-based Specialty Brokerage Services, adding wholesale distribution capacity to its platform. ISC was named among the 2026 5-Star Wholesale Brokers and MGAs - a ranking based on a survey of retail producers nationwide across 20 coverage areas rather than figures reported by ISC itself.
The Onex/KKR ownership transition fits a broader pattern of MGA platforms scaling through consolidation and outside capital. For RetailFirst, the question is whether ISC's strategic direction and service continuity hold through that transition - and whether the Onex deal, if not yet closed, introduces any uncertainty into a relationship the carrier is committing to at the same moment.
