What Aon does

Aon plc is a global professional services firm headquartered in London and incorporated in Ireland, listed on the NYSE under ticker AON. Founded in 1982 through the merger of Combined Insurance and Ryan Insurance Group, the company operates across 120+ countries serving multinational corporations, insurance carriers, employers, and financial sponsors. Its business is organized around two integrated pillars: Risk Capital (insurance brokerage and risk transfer, claims management, reinsurance intermediation, risk analytics, and risk retention) and Human Capital (health and benefits, human capital analytics, investments, pensions and retirement, talent and rewards, and workplace wellbeing).

Revenue is generated through a mix of commission-based insurance placement, subscription and retainer arrangements, professional services fees, and reinsurance transaction commissions across four reporting streams. The company has invested $1 billion in a digital transformation initiative called the 3x3 Plan, which has produced proprietary AI platforms including Aon Broker Copilot (generative AI for insurance placement, launched June 2025), SkillsGraph (workforce analytics), and People Insights (talent assessment), supported by a five-tier integrated data architecture and a multi-blockchain stablecoin payment capability demonstrated in March 2026.

Underlying Aon's offering is a large proprietary data asset base: the Radford McLagan Compensation Database covers 30+ million employees across 115 countries and 150 job functions, $650 billion in health claims data supports benefits analytics, and cyber benchmarking covers 10,000+ clients. Recent scale moves include the $13.4 billion acquisition of NFP Corp. (April 2024) and the subsequent $2.7 billion divestiture of the majority of NFP's wealth business to Madison Dearborn Partners (September 2025). FY 2025 revenue reached $17.2 billion with operating margin of 34.1% in Q1 2026 and return on equity above 45%.
