Marsh & McLennan Companies, Inc.

The filings describe a business whose revenue and operating income have risen each year since 2022, but whose balance sheet has become more leveraged since 2023. The Beneish M-Score is -2.472, which is below -1.78 and therefore not in the elevated manipulation-risk zone. This is a screening model, and the result does not indicate that the reported figures are wrong. The Piotroski F-Score is 7 of 8 computable signals, which is a high count on the simple profitability, leverage and efficiency checks it runs. The Altman Z″-Score is 2.86, in the safe zone, but the label notes that Altman Z is not designed for banks or financial firms, so this result should be treated with caution for a brokerage and consulting firm. The Fog Index of 17.16 falls in the hard-to-read band of 14 to 18, which matters because the MD&A is where management explains results in its own words. Operating cash flow of $5.29 billion was 1.27 times net income of $4.16 billion in 2025, which suggests cash generation has kept pace with reported profit. Narrative items worth tracing in the filings include the Thrive program and Business Client Services, which the risk factors say may not be fully realized, Mercer's Wealth business, the defined benefit pension plan obligations, and the decline in fiduciary income that the risk factors tie to lower interest rates. Equity method investments of about $327 million add a smaller exposure. Taken together, the scores do not flag manipulation, but the debt built up since 2023 and the dense MD&A language are the parts that call for a closer read.

Catalyst.According to the 2025 annual figures, revenues rose to $26.98 billion from $24.46 billion, a 10.3% year-over-year increase. Operating income reached $6.22 billion versus $5.82 billion in 2024, and net income reached $4.16 billion versus $4.06 billion. In the 10-Q for the period ended September 30, 2026, management reports that the company repurchased 11.4 million shares for $2.0 billion over the nine months and remains authorized to buy back about $3.7 billion more. The MD&A also says roughly 52% of total revenue is non-U.S. based, and a 10% move across major currencies would change full-year net operating income by about $129 million.

Hidden risk.The most material tension may be the debt level. Long-term debt was $18.32 billion at the end of 2025, down from $19.43 billion in 2024 but up from $11.84 billion in 2023. Equity was $15.31 billion, so long-term debt was roughly 1.20 times equity. The risk factors say the current debt level could adversely affect financial flexibility and that credit rating downgrades would raise financing costs. The risk factors also describe significant uninsured exposures from errors and omissions and breach of fiduciary duty claims. Readers may want to look at Note 17, which the filing incorporates by reference, for the claims detail.
