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.
New York specialty insurance (NYSE: AIZ) ~$11.5B FY2024 revenue; 180M mobile devices protected, AT&T/T-Mobile/Verizon carrier programs, Connected Living platform competing with Asurion and SquareTrade.
About
Assurant, Inc. is a New York City-based specialty insurance company — publicly traded on the New York Stock Exchange (NYSE: AIZ) as an S&P 500 Financials component — providing specialty insurance, extended warranties, and financial protection products through three segments: Global Housing (lender-placed homeowners insurance for mortgage servicers, renters insurance, and flood insurance), Global Lifestyle (mobile device protection programs for wireless carriers — AT&T, T-Mobile, Verizon; extended warranties for consumer electronics, appliances, and vehicles), and Global Preneed (life insurance for pre-arranged funeral plans) through approximately 14,000 employees in 21 countries. In fiscal year 2024, Assurant reported revenues of approximately $11.5 billion, with adjusted EBITDA growth driven by strong performance in the mobile device protection and connected living programs embedded in AT&T, T-Mobile, and Verizon wireless service bundles — Assurant's Global Lifestyle segment insures approximately 180 million mobile devices worldwide through carrier-embedded device protection plans that are offered at point-of-sale with wireless service activation. CEO Keith Demmings has focused Assurant's strategy on the Connected Living platform — expanding beyond device repair/replacement protection into smart home device management, tech support services, trade-in programs, and connected device subscriptions that create recurring revenue beyond the per-device insurance premium. Assurant's lender-placed insurance (LPI) business — providing homeowners insurance for mortgage borrowers whose own insurance has lapsed or been cancelled — benefits from rising catastrophe activity (hurricanes, wildfires) that makes voluntary insurance markets unaffordable in high-risk coastal and wildfire-prone areas, increasing the population of mortgage borrowers requiring lender-placed coverage.
