About
Arthur J. Gallagher & Co. is a Rolling Meadows, Illinois-based global insurance brokerage and risk management company — publicly traded on the New York Stock Exchange (NYSE: AJG) as an S&P 500 Financials component — providing commercial property/casualty insurance brokerage, employee benefits consulting, and risk management services to businesses and organizations worldwide through approximately 58,000 employees following the completion of the AssuredPartners acquisition. The defining transaction of 2025 was Arthur J. Gallagher's closing of the $13.45 billion acquisition of AssuredPartners — the largest sale of a US insurance broker to a strategic acquirer in industry history — adding 10,900 employees, approximately $2.9 billion in pro forma revenues, and 400 offices across the United States, United Kingdom, and Ireland, with particular middle-market strength in transportation, energy, healthcare, and government contracting. The AssuredPartners combination accelerates Gallagher's position as the third-largest insurance broker globally (behind Marsh & McLennan and Aon), with combined annual revenues exceeding $14 billion. CEO J. Patrick Gallagher Jr. has led the company's strategy of organic growth supplemented by a relentless acquisition program of regional and specialty insurance brokers — Gallagher has completed 40-50+ acquisitions per year in recent years — building a national and international distribution network that can cross-sell specialty insurance products across AssuredPartners' 400 acquired office locations. Gallagher's Risk Management Services division (claims adjusting and administration for self-insured corporations and government entities) provides a second business line that diversifies revenue from insurance brokerage commission and fee income.
