(Reuters) — Insurance broker Marsh reported a rise in fourth-quarter profit on Thursday, helped by robust performance in its risk and insurance services business. Brokers’ performance is closely related to the insurance industry’s numbers, as their commissions are tied to the premiums insurers charge. Earlier this week, rival brokerage Brown & Brown also reported a higher profit, but shares fell as investors balked at declining organic growth. Shares of Aon and Brown & Brown also ended 2025 in the red. Revenue in Marsh’s risk and insurance services business came in at $4 billion for the three months ended December 31, up 9% from a year earlier.
