Company Overview
About American International Group
American International Group, Inc. (AIG) is a New York City-based global commercial property-casualty insurance company — publicly traded on the New York Stock Exchange (NYSE: AIG) as an S&P 500 Financials component — providing commercial insurance (property, casualty, financial lines, specialty), personal insurance, and reinsurance to businesses, organizations, and individuals in 200+ countries through approximately 26,000 employees. AIG has completed a decade-long strategic transformation from the systemically important financial institution (SIFI) that required a $185 billion US government bailout during the 2008 financial crisis — divesting life insurance (AIG Life and Retirement separated as Corebridge Financial, NYSE: CRBG, with AIG owning 48% stake following Corebridge's 2022 IPO and ongoing stake sales), non-core property assets, and non-insurance financial businesses — focusing the company exclusively on global commercial and specialty P&C insurance. In fiscal year 2024, AIG reported revenues of approximately $27 billion with adjusted after-tax income growing as underwriting profitability improved following the combined ratio improvement initiatives. CEO Peter Zaffino has repositioned AIG as a "best-in-class" global commercial insurer: achieving combined ratio below 90% in its General Insurance segment, expanding the portfolio toward specialty lines (financial lines — D&O, E&O, cyber insurance; marine and energy insurance; aerospace) with superior pricing power versus commodity commercial P&C. AIG's complete exit from the low-margin high-volatility consumer auto and homeowners insurance markets (sold to Safeco/Liberty Mutual, Assurant partnerships) refocuses underwriting capacity toward commercial and specialty lines with better long-term profitability.
Business Model & Competitive Advantage
AIG's global commercial insurance model creates competitive advantages through the cross-border international risk expertise and global program capability for multinational companies: a Fortune 500 technology company with operations in 60 countries needs property and liability insurance covering manufacturing facilities in Malaysia, office buildings in Germany, product liability in California, and directors and officers (D&O) coverage in the US — coordinated through a single global insurance program that AIG structures with local admitted policies in each jurisdiction, aggregating the program under a master policy. AIG's Lexington Insurance Company (the largest US admitted excess and surplus lines insurer) handles non-standard and high-risk property and casualty placements that standard insurance markets decline — chemical plants, offshore oil rigs, earthquake-exposed commercial real estate — generating premium revenue at higher rates than standard market admitted insurance. The specialty financial lines platform (AIG's cyber insurance, M&A representations and warranties insurance, management liability D&O) positions AIG in the fastest-growing insurance categories driven by regulatory complexity, technology risk, and transactional insurance demand.
Competitive Landscape 2025–2026
In 2025, AIG competes in global commercial P&C insurance against Chubb (NYSE: CB, $52B revenue, global commercial and personal insurance leader), Zurich Insurance (SWX: ZURN, Swiss commercial and specialty insurance), and AXA (PAR: CS, French global insurer) for large commercial account property and casualty placements, multinational program insurance mandates, and specialty lines financial and cyber risk coverage. The commercial property insurance market hardening (property rates increasing 20-30% annually in catastrophe-exposed markets following Hurricane Ian, Hurricane Harvey, and wildfire losses) benefits AIG's commercial property underwriting profitability as price increases exceed loss trend. Cyber insurance market evolution (AI-driven cyberattacks, ransomware-as-a-service, and geopolitical threat actor activity increasing cyber loss frequency and severity) requires AIG's cyber underwriting teams to continuously update cyber risk modeling and policy terms. The 2025 strategy focuses on Corebridge Financial stake reduction (monetizing remaining stake toward eventual full exit), commercial P&C underwriting profitability improvement (combined ratio toward 88-89%), and specialty lines market share expansion in financial lines, cyber, and transactional liability.
