AOn

Aon plc is a multinational professional services company that provides risk, retirement, and health solutions to clients around the world. The firm operates across risk management, insurance and reinsurance brokerage, and human capital services, including retirement and health benefits consulting and data analytics. Aon serves corporations, governments, and individuals, helping to assess and manage financial risk, design compensation and retirement programs, and optimize health and welfare offerings.

The company traces its roots to a group of insurance brokerages that expanded globally and united under the Aon brand during the 20th century. A notable milestone was the 2010 acquisition of Hewitt Associates, which broadened Aon’s capabilities in retirement and health benefits consulting and gave rise to the Aon Hewitt identity, now integrated into the broader Aon platform. Since then, Aon has grown to be one of the largest professional services firms focused on risk and people, with a global network of offices.

Aon plc is listed on the New York Stock Exchange under the ticker AON and is a member of the S&P 500 index. The company employs tens of thousands of people worldwide and maintains a broad client base across various industries and sectors.

In recent years, Aon’s strategic activities have included pursuing larger-scale mergers to expand capabilities. In 2021, a planned merger with Willis Towers Watson was terminated after regulatory obstacles, leaving Aon to pursue growth through organic expansion and smaller acquisitions.
