Marsh McLennan has revealed that, effective January 2026, it will change its brand to Marsh. As part of the transition, Guy Carpenter will rebrand as Marsh Re in 2027, reflecting its position within the group’s reinsurance and capital advisory operations.

Following a transition period beginning in 2027, all four businesses will operate under the Marsh brand.
Marsh and Mercer will go to market as Marsh, while Oliver Wyman will continue to operate under its name as Oliver Wyman, a Marsh business, and its parent unit, Oliver Wyman Group, will become Marsh Management Consulting.
The company’s stock ticker will change to “MRSH” in January 2026.
John Doyle, President and CEO of Marsh McLennan, commented, “In an increasingly complex environment, clients are seeking advice, solutions and insights that draw on expertise from across our firm.
“The changes we announce today reflect the way we continue to bring our Company together to better help our clients overcome challenges and find opportunity.”
“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.”
John Jones, Chief Marketing and Communications Officer of Marsh McLennan, said, “Unifying under one brand will accelerate the impact we deliver to the marketplace and give clients even greater confidence to thrive through the power of perspective.
“The new Marsh brand comes to life with a new logo – a bold design that represents the greater impact we can have with clients and the unique perspectives we offer.”
With all this in mind, the firm has also created a new unit, Business and Client Services (BCS), to accelerate innovation and centralise investments in operational excellence, data, AI and analytics.
BCS brings together the firm’s technology, data and operations teams under the leadership of Paul Beswick, Marsh McLennan’s Chief Information and Operations Officer
Through BCS, the firm said it will create a data and technology ecosystem that harnesses AI and other technologies to enhance client outcomes across its businesses while delivering operational excellence and efficiency.
Beswick observed, “The rapid development of AI, and the insights it can derive from our data, will help unlock new opportunities for our clients and colleagues.
“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.”
John Doyle concluded, “With the changes announced today, our brand will embody the greater value we can create for all our stakeholders, while BCS will drive enhanced client service. Both initiatives reflect our steadfast commitment to delivering meaningful outcomes and exceptional experiences for our clients and colleagues.”
