Marsh & McLennan Companies (MSN.DE) Stock Analysis & Winston Score

Marsh & McLennan helps businesses and governments manage risk. Its main brands — Marsh, Guy Carpenter, Mercer, and Oliver Wyman — offer insurance brokerage, reinsurance, employee benefits consulting, and management consulting. It is one of the largest insurance brokers in the world, serving clients across industries like healthcare, energy, and finance. The company earns money through fees and commissions paid by clients who use its advisory and brokerage services, not by taking on insurance risk itself. It operates in over 130 countries and generates roughly $23 billion in annual revenue, giving it significant scale and deep client relationships that are hard for smaller rivals to replicate. The key growth driver is rising demand for risk management as businesses face more complex threats like cyberattacks and climate-related losses, though a slowdown in corporate spending on consulting services remains a notable risk to earnings.
