Arthur J. Gallagher (AJG)

Gallagher’s brokerage business covers a broad range of insurance needs, including property and casualty, employee benefits, professional liability, cyber risk, construction, transportation, healthcare, and other sector-specific exposures. Because brokers are typically paid through commissions and fees rather than by taking underwriting risk directly, Gallagher’s earnings profile is tied to client retention, new business wins, premium trends, and the depth of its carrier relationships.

The company also operates a risk management segment that provides third-party claims administration and related services, particularly for organisations that self-insure part of their exposure. These services can include claims handling, loss control, analytics, and programme administration, helping clients manage the financial and operational impact of workplace injuries, liability claims, and other insured events.

Headquartered in the United States, Gallagher has built a significant international presence through organic growth and acquisitions, with important operations in markets such as the United Kingdom, Canada, Australia, and New Zealand. Its scale, acquisition-driven expansion strategy, and focus on specialised advice make it one of the major listed insurance brokers worldwide.
