Why bro has worst organic revenue in recent quarters compared to peers

Brown & Brown (BRO) has indeed hit a wall on organic growth recently, posting flat (0.0%) organic growth excluding contingents in Q1 2026 and a 2.8% decline in Q4 2025. This stands in stark contrast to larger peers like Marsh McLennan and Aon, which have continued to deliver 4% to 6% organic growth over the same period.

While BRO's total revenue surged 35% in Q1 2026, that was almost entirely bought via the $9.8 billion Accession Risk Management Group acquisition. The underlying organic engine is being dragged down by a very specific confluence of idiosyncratic and macro factors:

1. The Startup Broker Defection

The most disruptive internal issue has been a mass employee exodus. Last year, roughly 275 employees left to join a competing startup broker. By the end of Q1 2026, management disclosed that this defection had siphoned off approximately $31 million in annualized revenue (up from $23 million the prior quarter). Beyond the direct top-line hit (which accounted for roughly a $10 million drag in Q1 alone due to renewal timing), the ongoing litigation and operational disruption have severely hampered net new business.

2. Plunging Catastrophe (CAT) Property Rates

BRO has heavy exposure to the CAT property market, which is currently experiencing steep rate declines of 15% to 35%. Because broker commissions are directly tied to premium rates, this softening pricing environment has disproportionately compressed organic growth in BRO's Specialty Distribution segment, leaving them more exposed to the property cycle than highly diversified peers.

3. The Flood Claims Processing Hangover

BRO is facing exceptionally tough year-over-year comparables related to flood claims. In early 2025, they recognized a massive surge in flood claims processing revenue. The normalization of these claims created a massive headwind in recent quarters—specifically dragging down the Specialty Distribution segment by 300 basis points and the Retail segment by 100 basis points in Q1 2026.

4. Pharmacy Consulting Business Model Shift

Within their retail segment, BRO is actively transitioning its pharmacy consulting business from a volume-based revenue model to a per-member/per-employee model. Management has explicitly stated this structural transition will create an ongoing 50 to 100 basis point drag on organic growth for several quarters until the new baseline is established.

5. Integration Indigestion

While peers are operating business-as-usual, BRO is in the midst of digesting the massive Accession acquisition, which added over 700 locations and 23,000 staff (folding Risk Strategies into Retail and One80 into Specialty). The sheer operational bandwidth required to integrate a $9.8 billion target naturally distracts from core organic growth initiatives.

Ultimately, while peers are navigating a generally softer commercial property market relatively unscathed, BRO is absorbing that same macro headwind while simultaneously restructuring a business line, fighting off a localized talent raid, and digesting a transformative acquisition.
