Marsh McLennan to rebrand to Marsh
Marsh McLennan, a New York-based insurance broking and professional services company, will continue its brand simplification and transition to the brand of “Marsh” in January 2026.
The public company will also switch its stock ticker to “MRSH” in January.
The company, which was founded in 1905, changed its brand from "Marsh & McLennan Companies" to "Marsh McLennan" in April 2021.
The company comprises four major subsidiaries: Marsh (insurance); Guy Carpenter (reinsurance); Mercer (HR and asset management); and Oliver Wyman (management consulting). The company has more than 90,000 people advising clients in 130 countries.
The businesses will adopt the Marsh brand beginning in 2027 after a transition period. Marsh and Mercer will go to market as Marsh, while Guy Carpenter will become Marsh Re. Oliver Wyman will go to market as Oliver Wyman, a Marsh business, while its parent unit Oliver Wyman Group will become Marsh Management Consulting.
The company in a press release said the new Marsh brand will better represent its capabilities in risk, reinsurance and capital, people and investments, and management consulting.
“Today, Marsh stands for excellence in risk advising and insurance broking. The new Marsh brand will also symbolize everything our company has to offer: a distinct combination of capabilities in professional services, scale and specialization for clients, enabled by cutting-edge AI and analytics,” said John Doyle, president and CEO of Marsh McLennan.
The company also announced the creation of a business and client services (BCS) unit that will combine its technology, data, and operations teams. Under the leadership of Paul Beswick, chief information and operations officer, the unit will form a “data and technology ecosystem” that leverages AI to improve internal operations and client outcomes.
“The rapid development of AI, and the insights it can derive from our data, will help unlock new opportunities for our clients and colleagues,” said Beswick. “By harnessing this powerful tool to simplify operations and elevate service quality, we will drive innovation and deliver efficiencies to reinvest in client value and growth.”
