Oakmark U.S. Concentrated Strategy stated the following regarding Marsh & McLennan Companies, Inc. (NYSE:MRSH) in its Q2 2026 investor update:
“Marsh & McLennan Companies, Inc. (NYSE:MRSH) is the world’s largest insurance broker and risk management firm. In our view, it is well-positioned as a leader in what we think is an oligopolistic market, benefiting from strong organic revenue growth and a long track record of consistent margin expansion. We think this strong performance is poised to be supplemented by management’s unifying re branding efforts, which center on rolling out an expense program, leveraging AI to improve productivity, and centralizing its technology and operations to drive efficiencies and pro duce significant savings over time. Despite solid historical performance, dominant positioning, and continued operational improvements, the stock has fallen out of favor due to softening insurance rates and macroeconomic uncertainty, creating an opportunity to invest in an in dustry-leading company at an attractive price.”
