Marsh McLennan is rebranding. From January 2026, it will be known as Marsh.

At the same time, a new Business and Client Services unit, led by Paul Beswick, chief information and operations officer, will be created to centralise technology, data and operations across the company.

Four businesses will adopt the Marsh name from 2027. Marsh and Mercer will go to market as Marsh. Guy Carpenter will be Marsh Re. Oliver Wyman will remain Oliver Wyman, a Marsh business, while Oliver Wyman Group becomes Marsh Management Consulting.

John Doyle, president and CEO, 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.”

Chris Lay (pictured), CEO, UK, MMC, added: “Bringing together our businesses under the Marsh brand will help us be the most impactful professional services firm for our clients. We’ve already seen the impact we can deliver as one company – from our ongoing work in Ukraine to support recovery and economic growth to our global cyber data, analytics, and modelling centre of excellence. The creation of BCS will enable us to accelerate innovation and investment in our operations, technology and AI offering, addressing the challenges that businesses face across the region.”

The new Marsh brand comes with a new logo and a new stock ticker symbol, MRSH, from January 2026.
