Marsh McLennan to rebrand as Marsh in 2026

Marsh McLennan has revealed plans for a rebranding strategy, which will see the company operate under the name Marsh, starting in January 2026.

The move is designed to unify the company's expertise in reinsurance, people, risk, investment and consulting services under a single brand identity.

After a transition period, Marsh McLennan’s four businesses will adopt the new brand from 2027.

Consequently, Marsh and Mercer will be marketed under the Marsh brand, Guy Carpenter will be rebranded as Marsh Re, and Oliver Wyman will operate as Oliver Wyman, a business of Marsh.

Meanwhile, the Oliver Wyman Group operating unit will be renamed Marsh Management Consulting.

The company's stock ticker will also be updated to 'MRSH' in January 2026.

Marsh McLennan is also establishing a new division, Business and Client Services (BCS). It will be spearheaded by the company's chief information and operations officer Paul Beswick.

BCS aims to create a cohesive data and technology environment that utilises AI and other technologies to improve client services while also enhancing operational efficiency.

Marsh McLennan CEO and president John Doyle said: “The new Marsh brand will also symbolise everything our company has to offer: a distinct combination of capabilities in professional services, scale and specialisation for clients, enabled by cutting-edge AI and analytics.

“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.”

Beswick stated: “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.”

In August 2025, Marsh, in collaboration with Oliver Wyman, introduced BrokerSafe, an insurance facility providing auto liability coverage for US-based freight brokers.
