Janus Henderson Investors Global Sustainable Equity Fund stated the following regarding Arthur J. Gallagher & Co. (NYSE:AJG) in its fourth quarter 2025 investor letter:
“The largest individual detractors included Spotify, Arthur J. Gallagher & Co. (NYSE:AJG), and Uber. Arthur J Gallagher faced continued negative sentiment around insurance-related companies, with shares underperforming due to a combination of investors moving away from typically more defensive stocks and company specific factors. The company’s earnings were impacted by accounting noise from the AssuredPartners acquisition and a miss on brokerage organic growth, which led to questions about growth deceleration. However, the closing of the AssuredPartners deal has cleared a major overhang, and its management reiterated confidence in delivering robust revenue and earnings growth, even as property pricing softens. There is growing demand for insurance given the emergence of new risks such as climate change, cyber risk, and the risks associated with the provision of retirement and healthcare services to an aging population.”
