The $40 Billion Rollup: Why PE Can’t Stop Buying Insurance Brokerages
Inside the consolidation machine reshaping insurance distribution
Between 2020 and 2025, private equity firms deployed an estimated $40-50 billion into insurance distribution; more than any other insurance segment. As I examined in my recent analysis of PE’s insurance investment playbook, distribution attracts PE because the value creation is operational efficiency rather than operational transformation.
But the scale of what’s happening deserves closer examination. This isn’t just consolidation – it’s a fundamental restructuring of market power in insurance distribution.
The Concentration Story
The market’s consolidation trajectory tells a story the aggregate statistics miss.
In September 2021, 152 unique buyers competed for insurance agency acquisitions. By September 2025, that number had collapsed to just 96, a 37% reduction in market participants even as deal activity remained elevated.
The concentration at the top is even more striking. The top 10% of buyers controlled 56% of all deals by 2025, up from 46% four years earlier. Just three firms – BroadStreet Partners, Hub International, and Inszone Insurance Services – accounted for 25% of all transactions over trailing four quarters in early 2025.
BroadStreet alone completed 69 deals in 2025, 90 in 2024, and 59 in 2023, maintaining its position as one of the most active buyers for three consecutive years. This isn’t diversified competition; it’s platform accumulation by a shrinking group of increasingly dominant acquirers.
The Price of Scarcity
As buyer concentration intensified, valuations followed. Average EV/EBITDA multiples increased 27% between the 2019-2021 and 2022-2025 periods: a premium reflecting intensifying competition among fewer, larger buyers for quality assets.
The mega-deals have grown correspondingly. Arthur J. Gallagher announced the $13.45 billion AssuredPartners acquisition in late 2024: GTCR’s exit from a platform they had originally acquired in 2011, sold to Apax in 2015, reacquired in partnership with Apax in 2019, and built through hundreds of bolt-on acquisitions before this final exit.
These transactions aren’t transformational investments. They’re the logical endpoint of rollup economics: consolidate, optimize, exit to a strategic buyer. AssuredPartners was built through this exact playbook across multiple PE ownership cycles, and its sale to Gallagher, one of the world’s largest insurance brokerages, represents the terminal transaction PE sponsors are ultimately building toward.
The Platform Lifecycle
The AssuredPartners trajectory illustrates the distribution rollup lifecycle: GTCR acquired the platform in 2011, built it through acquisitions, sold to Apax in 2015, partnered with Apax to reacquire in 2019, continued building, then exited to Gallagher in 2024-2025. That final sale to a strategic buyer ends the PE cycle – Gallagher integrates AssuredPartners into permanent operations rather than positioning for another flip.
Each stage of this lifecycle creates returns for the PE sponsors involved. Each stage also increases the platform’s size and the multiple required for the next buyer to achieve similar returns. The question is where this progression leads when strategic exit is the only remaining option.
Over 35,000 independent agencies still operate in the US market. From PE’s perspective, this represents a nearly inexhaustible supply of acquisition targets. But as buyer concentration intensifies and multiples expand, the economics become increasingly challenging. The platforms that entered at 13x multiples face different math than those acquiring at 17x.
The Fragmentation Paradox
Here’s what makes the distribution pattern worth examining: Despite a decade of aggressive consolidation and $40-50 billion in capital deployment, the market’s fundamental structure persists. Those 35,000 independent agencies still exist. PE hasn’t consolidated the industry, it has created larger platforms that continue to feed on smaller targets.
This is rollup economics working exactly as designed. Complete consolidation isn’t the goal. The goal is building platforms large enough to command premium exit multiples from strategic acquirers or larger PE funds.
But the buyer concentration data suggests the end game may be approaching. With unique buyers declining from 152 to 96 and the top 10% controlling 56% of deals, the number of potential exit partners is shrinking even as platform sizes grow. At some point, the platforms become too large for PE-to-PE transactions and require strategic buyers: Gallagher, Aon, Marsh, Brown & Brown, willing to pay premium multiples for permanent integration.
The Gallagher-AssuredPartners deal is exactly this dynamic playing out. After three PE ownership cycles, the platform reached a scale where only a strategic buyer made sense. That’s not a failure of the model, it’s the model working as designed. But it does mean the rollup runway has an endpoint.
The question for investors evaluating insurance opportunities isn’t whether distribution rollups work. Clearly they do, and have generated substantial returns for the sponsors involved. The question is whether the current multiple environment and buyer concentration dynamics have already extracted most of the accessible value, or whether the fragmented agency base provides runway for continued platform building.
Understanding that dynamic helps clarify where different types of capital might find advantages: in distribution, or in segments PE systematically avoids.
