Marsh & McLennan: Why Oliver Wyman Holds The Key To Its Future Growth! 

Marsh McLennan had a solid start to 2025, reporting a 9% increase in revenue for the first quarter, driven by a 4% growth in underlying revenue and contributions from acquisitions made in 2024. The company saw growth across all four of its businesses: Marsh, Guy Carpenter, Mercer, and Oliver Wyman. Adjusted operating income rose by 8%, although the adjusted operating margin slightly declined by 20 basis points, reflecting some seasonality at McGriff. The adjusted earnings per share (EPS) grew by 5%.
