Summary
Kelso & Company has completed its exit from Accession Risk Management Group, selling the Boston-based insurance services platform to Brown & Brown, Inc. (NYSE: BRO) for approximately $9.83 billion in a transaction structured primarily as a cash deal. The completion marks a significant milestone in private equity insurance sector M&A, exemplifying the substantial value creation achievable in middle-market insurance brokerage consolidation over an extended investment horizon.
Kelso's decade-long transformation of Accession began in 2015 when the firm partnered with management to scale a regional retail insurance broker into a national distribution platform. The growth trajectory was substantial: revenue expanded from $130 million at initial investment to $1.7 billion at exit, while the employee base grew from 500 professionals to approximately 5,500. This expansion was driven by both organic growth and an aggressive acquisition strategy encompassing more than 180 add-on acquisitions, a disciplined approach to consolidating a fragmented market.
Accession's operating structure comprises two distinct business units. Risk Strategies operates as the primary retail brokerage, offering comprehensive risk management advice and insurance placement across property and casualty, employee benefits, private client services, consulting, and wealth solutions. One80 Intermediaries, established by Accession in 2019, evolved into a leading wholesaler and program manager with rapid geographic scaling to more than 55 locations across the United States and Canada, demonstrating successful execution of a parallel distribution model within the platform.
The transaction represents a strategic combination of two major insurance distribution players, with Brown & Brown acquiring a mature, diversified platform that complements its existing operations. For Kelso, the sale concludes a value-creation narrative spanning ten years of operational partnership and disciplined capital allocation in the insurance services sector. The transaction underscores sustained institutional appetite for consolidated insurance brokerage platforms and validates the middle-market private equity model in regulated distribution businesses.
