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.
