What does the change mean for clients?

For clients, a new, expanded Marsh brand makes it simpler to access our full range of solutions and our comprehensive expertise and capabilities across risk, strategy and people with no change to the client service or solutions that clients have come to expect from each of our businesses.

When will the change take effect?

The transition to one brand will occur over the course of 2 years, starting in January 2026 and ending in 2027.

  • Marsh will become Marsh Risk.
  • Guy Carpenter will become Marsh Re.
  • Mercer will become Marsh People and Investments.
  • Oliver Wyman will become Oliver Wyman, a Marsh business.

What aspects of the business will remain the same?

This is a change to our brand strategy, not our business structure. We will continue to serve clients as we do today with solutions and services across risk, strategy and people. We will continue to focus on our clients’ needs and specialize to support them in the best way possible. Current client teams and contracts will remain in place.

What's next for Marsh?

This is an important milestone in our company’s history. We are shaping our future and unlocking new possibilities for our clients and our company with a brand that can represent the most impactful professional services firm in the world across risk, strategy and people.
