In a deal poised to redefine the contours of the insurance industry, Brown & Brown Inc. will acquire Accession Risk Management Group Inc. for $9.825 billion, catapulting the Florida-based titan to even greater heights. The acquisition was unveiled Tuesday in a joint statement, outlining a cash and debt-free transaction that is expected to close in Q3 of 2025.

Legal titans are steering the ship: Skadden Arps Slate Meagher & Flom LLP is advising Brown & Brown, while Debevoise & Plimpton LLP represents both Accession and its private equity backer, Kelso & Co.

Powerhouses Combine for a High-Stakes Play

Brown & Brown will acquire RSC Topco Inc., the holding entity of Boston-based Accession, in a transaction designed to fuel strategic growth.

“This union is more than numbers — it's a catalyst,” said J. Powell Brown, president and CEO of Brown & Brown. “Together, we will amplify our scale, our reach, and our innovation. This is about creating momentum in a consolidating marketplace.”

Once the dust settles, Accession’s Risk Strategies unit will integrate into Brown & Brown’s retail segment, with Accession CEO John Mina stepping into a senior leadership role within the merged company.

Merging Cultures, Strategies, and Ambitions

Mina described the deal as “one-of-a-kind,” emphasizing that Brown & Brown not only matched but exceeded what Accession was searching for in a strategic partner.

“We didn’t just want scale—we wanted strength, conviction, and cultural alignment,” Mina said. “This deal delivers all of that.”

The companies claim the merger will bolster insurance offerings, enrich client and carrier relationships, and serve as a springboard for revenue and earnings growth across the board.
