Marsh to rebrand Mercer starting September 2026

Marsh has announced that its people and investments business, Mercer, will adopt the Marsh brand name effective September 1, 2026. Mercer has been part of Marsh since 1959, focusing on investment goals, the future of work, and employee health and retirement benefits.

The decision follows a October 2025 announcement that Marsh would unify its various business units under a single brand to better reflect its collective scale and market impact. Pat Tomlinson, CEO of Marsh People and Investments (formerly Mercer), stated that a unified brand will allow the company to provide a broader range of capabilities and expertise to clients in a rapidly changing world.

Regional leaders, including Pedro Polo in Spain, noted that the transition aims to create stronger connections to Marsh’s full potential by combining expertise in risk, reinsurance, capital, people, investments, and strategic consulting.
