Aon PLC (AON)

Its business is weighted toward commercial risk and brokerage services, but Aon also has meaningful operations in reinsurance, health benefits, wealth consulting, and human capital advisory. The company connects clients with insurers and reinsurers, structures risk transfer programmes, provides analytics, and supports employers with workforce and benefits strategies. This advisory-led model gives Aon recurring exposure to insurance pricing cycles, client retention, and demand for risk management expertise.

Aon serves clients in more than 120 countries and employs around 60,000 people, giving it one of the broadest footprints in the global insurance services industry. Its scale is important because multinational clients often need consistent advice across jurisdictions, while insurers value brokers with deep data, distribution, and market access.

The company is domiciled in Ireland and maintains a major operating base in London, a key global insurance hub. Aon’s competitive position rests on its global network, sector expertise, analytics capabilities, and role as an intermediary in increasingly complex risk markets, including climate, supply chain, cyber, and employee health risks.
