# Arthur J. Gallagher & Co. Moat

Status: published. Policy: company-analysis-1.

Gallagher has a narrow switching-cost advantage, most clearly in claims administration, where integrated services, continuing service obligations and multi-year arrangements embed it in customer operations. Organic growth and performance bonus revenues support commercial value, but do not establish strong unilateral pricing power. Brokerage pricing depends substantially on carrier premiums and negotiated compensation. Acquisition integration, technology substitution and competitive pressure limit confidence in broader durability.

## switching_costs

Integrated claims services and continuing claims obligations create operational switching friction. Multi-year performance-fee arrangements and demonstrated organic fee growth support a current, limited advantage; migration costs and renewal rates are not quantified.

Durability: The contractual and service model appears across the 2023 and 2025 annual disclosures and remains supported by 2026 operating results. This supports persistence over contract and claims-service periods, without establishing exceptional long-term protection. Risk management represented only 13% of 2025 revenue.

Risks: Clients can develop in-house capabilities, including through AI. Competition, staffing costs, system failures and unfavorable contract renewals could weaken the advantage. These are principally disclosed possibilities, rather than demonstrated customer losses.

Invalidation: Repeated losses of established claims clients at renewal, successful transfers to competitors or in-house systems with little disruption, or sustained organic fee contraction accompanied by worsening contract economics would invalidate the switching-cost thesis.
