Shares of Marsh & McLennan (MMC) tumbled 5.76% in pre-market trading on Thursday following the release of its first-quarter 2025 financial results. The global professional services firm, which provides strategy, risk, and people solutions, reported mixed results that fell short of some Wall Street expectations.

Marsh & McLennan reported Q1 revenue of $7.06 billion, slightly missing the analyst estimate of $7.08 billion. While the company's adjusted earnings per share (EPS) of $3.06 surpassed the expected $3.02, investors seemed more focused on the revenue shortfall. The risk and insurance services segment, which is the company's largest business unit, posted an 11% increase in revenue to $4.76 billion, but still fell short of analyst projections.

Despite the overall revenue miss, there were some bright spots in the report. The consulting division showed stronger performance, with revenue rising 5% and exceeding forecasts. However, the adjusted operating income of $1.8 billion significantly missed the estimate of $2.19 billion, raising concerns about the company's profitability. The mixed results and the market's negative reaction highlight the challenges Marsh & McLennan faces in meeting the high expectations set by analysts and investors in the current economic environment.
