Marsh has benefitted from robust demand for its consulting and risk management services. This is buoyed by strong spending on insurance as organizations safeguard themselves against threats such as cyber-attacks and climate-related challenges.
In October 2025 it launched a new brand, and Marsh McLennan became Marsh in January 2026. The company has also successfully completed the integration of McGriff Insurance services. Full-year 2025 revenue grew 10 percent year over year to $27 billion.
Spending on U.S.-booked air volume in 2025 rose to $60 million. Marsh remains focused on travel cost containment and compliance to its travel policy. In this period, air and hotel reshopping tools have been embedded into its businesses.
Marsh has continued to survey the travel industry and relevant technology to ensure its travel program meets the firm's requirements.
