how AJG reported 5% organic growth/

While Brown & Brown (BRO) and Arthur J. Gallagher (AJG) are often lumped together as middle-market broker peers, their underlying business engines are built very differently.

While BRO's organic growth stalled out at 0% (excluding contingents) in Q1 2026 due to plunging property rates, AJG managed to power through and post 5% organic growth. They achieved this because their business model has massive "shock absorbers" that BRO either lacks or hasn't scaled to the same degree.

Here is exactly how AJG masked the property market drag and kept their organic growth engine humming:

1. The "Gallagher Bassett" Shield (Fee-Based Revenue)

AJG owns Gallagher Bassett, one of the largest Third-Party Claims Administrators (TPAs) in the world.

• The Mechanic: Gallagher Bassett does not rely on insurance premium rates; they charge flat fees to manage and process claims for self-insured corporations and carriers.
• The Impact: Because casualty and liability claims have been getting more frequent and complex, corporations are relying heavier on TPAs. This gives AJG a massive, predictable, recurring revenue stream that is completely immune to the softening property market.

2. A Massive Employee Benefits Division

The insurance market is currently "bifurcated"—property is cheap, but healthcare is expensive.

• The Mechanic: AJG has a substantially larger and more established global Employee Benefits and HR consulting division than BRO.
• The Impact: Medical inflation is currently running at 8% to 10%, meaning health insurance premiums for corporations are rising. Because AJG's benefits division earns commissions and fees tied to these rising healthcare costs, they are experiencing a "hard market" in benefits that perfectly offsets the "soft market" in property.

3. Less Structural Exposure to US Coastal Property

While AJG definitely felt the 7% to 9% drop in property rates, their exposure is highly diluted compared to BRO.

• Geographic Spread: BRO is headquartered in Florida with massive density in the Southeast and Gulf Coast. AJG is headquartered in Chicago with a massive international footprint (UK, Australia, Canada, New Zealand).
• Wholesale vs. Retail: BRO relies heavily on placing hard-to-write Excess & Surplus (E&S) coastal property through its Specialty division. AJG is much more heavily weighted toward standard retail casualty, liability, and cyber lines, where rates are actually still flat or rising.

4. Absence of Idiosyncratic Wounds

As noted earlier, BRO’s organic growth wasn't just hurt by the macro market—they suffered very specific, self-contained wounds. AJG simply didn't have these negative multipliers:

• No Mass Defection: BRO lost roughly 275 employees to a startup broker, dragging down organic growth by tens of millions in lost annualized revenue. AJG's producer retention remained stable.
• No Tough Flood Comps: BRO faced a severe year-over-year revenue comparison because they processed a massive surge of flood claims in the prior year. AJG didn't have this specific anomaly dragging down their Q1 comparisons.

The Bottom Line

AJG hit 5% organic growth because they are a highly diversified conglomerate. When their property commissions shrank, their healthcare commissions grew, and their fee-based claims processing division provided a rock-solid floor. BRO, on the other hand, is a more specialized, property-heavy operator, meaning when the wind and catastrophe markets soften, they take the hit directly on the chin.
