Evan G. Greenberg (born 1955) is an American business executive. He is the President and Chief Executive Officer (CEO) of the Zürich-based insurance company Chubb Limited (formerly ACE Limited).

Greenberg is the son of Corinne Phyllis Zuckerman and Maurice R. Greenberg, the former chairman and CEO of American International Group (AIG).^[1] He is also the younger brother of Jeffrey W. Greenberg, the former CEO of Marsh & McLennan.^[2]

After graduating high school at 17, Greenberg traveled the country working odd jobs, including cooking at a nursing home and bartending.^[3][4] He later attended New York University and the College of Insurance but did not graduate from either.^[2]

In 1975, Greenberg started working in insurance, initially working for New Hampshire Insurance Co. in its automobile policies department.^[5] He began working for AIG later that year as an underwriter.^[5] During the 25 years he worked for AIG, Greenberg held a number of senior management positions. He ran AIG's Japan and Korea operations from 1991 to 1994.^[4] He then oversaw all international property-casualty operations from AIG's New York offices.^[4] Greenberg was named president and COO in 1997 and was considered the heir apparent to take over as CEO of AIG.^[2][1]

Despite Greenberg being in line to take over the company, he left his position as president in September 2000.^[6] He spent a year away from work to spend time with his family.^[6] After seeing the impact of the September 11 attacks on the insurance industry, with insurers affected by large claims, Greenberg decided to take the opportunity to accept then-ACE CEO Brian Duperreault's offer to join ACE.^[6]

Greenberg joined ACE in November 2001 to lead the company's overseas unit.^[6] In June 2003, he was promoted to president and chief operating officer, and in May 2004, was named CEO.^[6] In May 2007, he was elected Chairman of ACE.^[7]

Following his promotion to CEO, Greenberg grew the company both through expansion of existing operations and through a strategy of acquisitions, acquiring 15 companies by 2015.^[5] In July 2015, Greenberg led a deal for ACE to acquire the insurance company Chubb for $28.3 billion,^[8] which was the largest merger deal in property and casualty insurance history.^[9] Shortly prior to the deal, he broke his ankle in a horse riding accident, and he worked on the merger while recovering.^[4] When the deal became official in January 2016, ACE adopted the Chubb name globally and Greenberg became chairman and CEO of Chubb.^[10] By 2021, Greenberg was credited in the media for having grown Chubb to the second-largest publicly listed insurance company in the U.S.^[11] and the largest non-injury insurer in the U.S. based on market value.^[12] As part of the acquisition plan to continue growing Chubb, he led an attempted acquisition bid for The Hartford in 2021. After making three offers that were each declined, he stated that Chubb would not continue to pursue the acquisition.^[11]

Following the merger, Greenberg has sought to grow Chubb's presence in Asia.^[13] He led the company's push to increase its holdings in Huatai Insurance, a China-based insurance company, by pursuing a regulatory change in China that would allow Chubb to become Huatai's majority owner. Officials passed the change in 2019^[12] and Chubb gained majority ownership of Huatai in 2022.^[14] In 2021, he led the company's acquisition of Cigna Group's Asian businesses that focused on health and accident insurance.^[13]

Greenberg is on the board of the National Committee on United States-China Relations and the US-China Business Council.^[15]
