Summary
Summary of the 8-K filed October 16, 2025. Cited figures are marked; the original filing is the authoritative source.
Marsh & McLennan (NYSE: MMC, to be renamed MRSH in January 2026) reported third quarter 2025 results on October 16, 2025, with consolidated revenue of $6.4 billiona, up 11% on a GAAP basis but only 4% on an underlying basis, which strips out currency and acquisition effects (principally the McGriff acquisition).
Operating income rose 6% to $1.17 billionb, while adjusted operating income rose 13% to $1.44 billion. GAAP diluted EPS was $1.51, flat year over year, and adjusted EPS grew 11% to $1.85. The gap between GAAP and adjusted results is largely driven by identified intangible amortization ($133 million in the quarter, up from $90 million) and McGriff integration costs, so investors should weigh the adjusted figures carefully.
The quarter's underlying growth was modest but steady. Marsh's underlying revenue rose 4% (U.S./Canada 3%, international 5%), Guy Carpenter grew 5%, Mercer grew 3%, and Oliver Wyman grew 8%. Interest expense jumped to $237 millionc from $154 million, reflecting higher debt following the McGriff financing, which weighed on pre-tax income that was essentially flat at $1.01 billion.
Management also launched a three-year Thrive efficiency program (restructuring costs of $46 milliond in the quarter) and created a Business and Client Services unit. Balance sheet and capital return items were active. Dividends payable of $441 million were recorded at quarter-end, the company repurchased $400 million of stock in the quarter ($1.0 billion year to date), and total debt rose to about $19.6 billion including short-term borrowings of $1.26 billion.
Nine-month operating cash flow of $3.1 billion was up sharply from $2.3 billion. The company also announced a rebranding to Marsh, with its four businesses adopting the Marsh name beginning in 2027 and a ticker change to MRSH in January 2026.

03—Questions
Frequently Asked Questions
Why did GAAP earnings growth lag adjusted earnings growth in Q3 2025?
Adjusted metrics exclude identified intangible amortization, which rose to $133 million from $90 million due to recent acquisitions such as McGriff, as well as noteworthy items like McGriff integration costs ($52 million), restructuring ($46 million), and changes in contingent consideration ($34 million). GAAP operating income therefore grew only 6%, and GAAP diluted EPS was flat at $1.51.
How much of the 11% revenue growth came from organic business activity?
Very little. Underlying revenue grew 4%, while the remaining growth came from acquisitions and dispositions (about 7 percentage points, mainly McGriff at Marsh U.S./Canada) and currency (about 1 point). Marsh U.S./Canada grew 22% on a GAAP basis but only 3% underlying.
What is driving the increase in interest expense and what does it mean for investors?
Interest expense increased to $237 million in Q3 from $154 million a year earlier, and to $725 million for nine months from $469 million. Total debt rose to roughly $19.6 billion, with short-term debt of $1.26 billion, largely reflecting borrowing tied to the McGriff acquisition. Higher interest costs reduce GAAP pre-tax income and make deleveraging and integration execution important for future margin expansion.
What is the Thrive program and what costs are expected?
Thrive is a three-year program launched in Q3 2025 focused on brand strategy, delivering greater value to clients, accelerating growth, and improving efficiency through process automation and optimization of the global operating model. Q3 restructuring charges were $46 million (total $96 million for nine months), and the company expects savings over time, though the filing does not quantify the total program cost or target savings.
What do the rebrand and ticker change mean for shareholders?
Marsh McLennan will change its brand to Marsh effective January 2026 and its NYSE ticker from MMC to MRSH. The four businesses (Marsh, Guy Carpenter, Mercer, Oliver Wyman) will adopt the Marsh brand beginning in 2027 after a transition period. The rename does not change the underlying business or share count, but investors should note the ticker change when tracking the stock.
