Aon has announced a new executive committee, just days after the company revealed that its $30 billion merger with Willis Towers Watson had been scrapped.

The committee is responsible for executing the firm's four-pronged ‘Aon United Blueprint’, which “creates new sources of value for clients, delivers more effective client service, drives innovation at scale and ensures a unique and sustaining colleague experience”.

Greg Case, Aon CEO, will lead the executive committee. Earlier this week, Aon extended his contract for an additional three years to April 2026. Chief financial officer (CFO) Christa Davies’ contract was also extended for the same period.   

According to Case, Aon is “moving forward at speed without the overhang of regulatory uncertainty or distraction of restructuring”. 

The committee will comprise four solution lines, five regions and five shared service functions.

The four solution lines include: commercial risk solutions, health solutions, reinsurance solutions and wealth solutions. According to Aon, global solution lines will play a critical role in understanding macro client trends and producing new solutions that address their unmet needs.

North America, Latin America, the UK, Europe, the Middle East and Africa (EMEA) and Asia-Pacific are the five regions. The five shared services include: business services, finance, legal, marketing and communications and the people organisation. 

Key additions to the new executive line-up, compared to the 'one firm' structure announced in January this year when Aon was still planning to merge, include Jennifer Bell as CEO of North America; Dave Guilmette as CEO of health solutions; Paul Rangecroft as CEO of wealth solutions; Amanda Nguyen as chief of staff; and Leslie Follmer as head of investor relations and environmental, social and corporate governance.

James Platt will continue to serve as chief operating officer, Maggie Westdale as CFO business, and Carlo Clavarino as executive chairman international.

Additionally, Lori Goltermann will continue to serve as CEO of enterprise clients, Andy Marcell as CEO of reinsurance solutions, Lambros Lambrou as CEO of commercial risk solutions, Julie Page as CEO of the UK, Eduardo Dávila as CEO of EMEA, Alejandro Galizia as CEO of Latin America, and Anne Corona as CEO of Asia Pacific.

Case added: “This team knows how to work together across geographies, solution lines and functions to bring the best of our firm to clients and is fully committed to accelerating innovation to better address unmet client need.”
