Steady Marsh faces softer insurance pricing
- Marsh makes most of its money from risk advice, insurance broking, and reinsurance work.
- In Q1 2026, Consulting grew 5% on an underlying basis, faster than Risk and Insurance Services at 3%.
- Soft insurance and reinsurance pricing is the main drag on the largest segment.
- The Thrive program targets efficiency, but management has also warned it may not fully realize the benefits.
- A $425 million Greensill litigation charge is now a real legal overhang.
A steady compounder with fresh overhangs
Marsh is still a high quality, slow and steady business. Clients use it to buy insurance, manage risk, design health and retirement plans, and get strategy advice. Those needs do not disappear in a weak economy, which gives the company a more stable base than many service firms.
The newest quarter kept the main thesis intact. In Q1 2026, Consulting grew 5% on an underlying basis, while Risk and Insurance Services grew 3%. That matters because soft insurance and reinsurance pricing is holding back the larger risk business. Consulting is helping offset that pressure.
The bull case is about scale, data, and cost control. Management reaffirmed its full year 2026 outlook for underlying revenue growth similar to 2025, continued margin expansion, and solid adjusted EPS growth. It also gave more detail on AI, saying the plan is to use proprietary data to drive growth, productivity, and efficiency.
The bear case is not hard to see. Insurance pricing can keep weighing on growth. Mercer's Career business was down 2%, which points to weaker project work in the U.S. and Canada. The $425 million Greensill litigation charge also adds a legal risk that is hard for outside investors to size.
Advice fees tied to client risk
Marsh earns fees and commissions by helping companies and governments understand risk and buy insurance. It also helps insurers and reinsurers manage risk through Guy Carpenter. In simple terms, it gets paid because risk is hard to price and clients need help.
The Consulting segment earns money from Mercer and Marsh Management Consulting. Mercer helps with health benefits, retirement and investment plans, and workforce advice. Marsh Management Consulting works on strategy, economic, and brand questions.
The model breaks when clients spend less on projects or when insurance pricing falls enough to slow commission growth. Lower fiduciary interest income can also hurt results. Fiduciary interest income is interest earned on client money held before it is passed along.
The company is also reshaping itself. It changed its brand to Marsh in January 2026 and is building Business and Client Services under the Thrive program. Thrive is meant to use automation and shared operations to cut costs, but execution is now a named risk in the 2025 10-K.
Four engines under one brand
Marsh Risk
Marsh Risk gives risk advice and insurance solutions to large and mid-sized clients. It is the core broking engine and is most exposed to insurance premium pricing.
Guy Carpenter
Guy Carpenter helps insurers and reinsurers with risk, reinsurance, and capital strategy. Its growth can slow when reinsurance pricing falls.
Mercer Health
Mercer Health helps employers design and manage health benefit plans. In Q1 2026, Health revenue increased 6% on an underlying basis.
Mercer Wealth and Career
Wealth advises on retirement and investment outcomes, while Career handles workforce advice. Wealth grew 5% underlying in Q1 2026, but Career fell 2% as project work stayed soft.
Marsh Management Consulting
This business gives strategic, economic, and brand advice. It grew 6% on an underlying basis in Q1 2026.
AI and automation
Management wants Marsh to be an AI winner by using its scale and proprietary data. The payoff should show up as new growth, better productivity, or lower costs.
Two segments, one bigger than the other
Segment mix uses Q1 2026 revenue from the 10-Q: $5.1 billion for Risk and Insurance Services and $2.6 billion for Consulting. Risk and Insurance Services is the larger segment, so soft pricing there matters most.
What could go wrong
Soft insurance pricing
High impact · High oddsRisk and Insurance Services grew 3% on an underlying basis in Q1 2026. Growth was helped by new business and renewals, but declining insurance premium rates were a drag. If insurance and reinsurance pricing keep falling, the largest segment may stay capped.
Greensill litigation
High impact · Medium oddsIn Q1 2026, Marsh recorded an estimated liability and legal expenses of $425 million related to the Greensill litigation. Management could not give much more detail because the case is ongoing. The open question is whether the final cost is higher than the amount already recorded.
Thrive execution miss
Medium impact · Medium oddsThrive is meant to improve efficiency through automation, workforce actions, and shared operations under Business and Client Services. The 2025 10-K warns that Marsh may not fully realize the benefits of Thrive and Business Client Services. A miss would weaken the margin story.
Consulting project weakness
Medium impact · Medium oddsConsulting is helping offset slower risk growth, but it is not risk free. Mercer's Career business fell 2% on an underlying basis in Q1 2026 due to lower project-related work in the U.S. and Canada. If clients keep delaying discretionary work, Consulting growth could slow.
AI and cyber disruption
Medium impact · Medium oddsManagement sees AI as a growth and efficiency tool, but the 2025 10-K also names digital disruption, AI change, and cyber threats as risks. Bad execution could let rivals move faster. A serious cyber or supply chain attack could hurt trust, which is central to the business.
In one breath

The biggest business issue is soft insurance and reinsurance pricing, which pressures Risk and Insurance Services. The biggest new legal issue is the $425 million Greensill litigation charge recorded in Q1 2026.
