Marsh McLennan and Businesses to Unify Under ‘Marsh’ Brand; New Unit Created

October 14, 2025

Marsh McLennan announced it will change its brand to “Marsh,” effective January 2026, and it has created a new unit, Business and Client Services (BCS), which aims to accelerate innovation and centralize investments in operational excellence, data, artificial intelligence (AI) and analytics.

“In an increasingly complex environment, clients are seeking advice, solutions and insights that draw on expertise from across our firm,” commented John Doyle, president and CEO of Marsh McLennan, in a statement. “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.”

The company’s four businesses will adopt the Marsh brand beginning in 2027, following a transition period. After that transition period, Marsh and Mercer will each go to market under the new Marsh brand. Guy Carpenter will become “Marsh Re.” Oliver Wyman will go to market as “Oliver Wyman, a Marsh business,” while the operating unit Oliver Wyman Group will become “Marsh Management Consulting.”

The company’s stock ticker symbol will become “MRSH” in January 2026.

“Unifying under one brand will accelerate the impact we deliver to the marketplace….,” according to John Jones, chief marketing and communications officer of Marsh McLennan. “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.”

Business and Client Services

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, the company said. Through BCS, the company 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.

“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.”

“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,” Doyle added.
