Aon plc operates as one of the world's largest insurance and reinsurance brokers, offering a comprehensive suite of risk and human capital solutions. The company's business model is primarily fee- and commission-based, generating revenue through two main segments: Risk Capital and Human Capital. Risk Capital, which accounts for approximately 67% of total revenues, provides commercial risk solutions (retail brokerage, cyber, and global risk consulting) and reinsurance solutions (treaty and facultative reinsurance, insurance-linked securities, and capital raising). Human Capital, representing about 33% of revenues, delivers health solutions (health and benefits brokerages) and wealth solutions (retirement consulting, pension risk transfer, and investment advisory). Geographically, Aon has a massive global footprint, serving clients in over 120 countries with significant operations in North America, EMEA, and the Asia-Pacific region. The firm maintains a strong competitive position as part of the 'Big Three' global insurance brokers, alongside Marsh McLennan and Willis Towers Watson. Aon leverages its proprietary data analytics, catastrophe modeling, and extensive market relationships to help clients navigate complex challenges related to property and casualty risks, cyber threats, and workforce management.
