Janus Henderson Forty Fund stated the following regarding Eli Lilly and Company (NYSE:LLY) in its fourth quarter 2025 investor letter:
“Relative performance benefited from several healthcare holdings, notably Eli Lilly and Company (NYSE:LLY). The global pharmaceuticals company reported strong third-quarter results, fueled by accelerating sales growth for its blockbuster glucagon-like peptide-1 (GLP-1) weight loss products, Mounjaro and Zepbound. The company has several pipeline drugs that are performing well in late-stage clinical trials. These include orforglipron, a once-daily oral GLP-1 medication, and retatrutide, which targets a higher degree of weight loss and could provide a strong compliment to the company’s other GLP-1 products. Eli Lilly reached an agreement with the U.S. government on pricing and access to GLP-1 drugs for Medicare and Medicaid users, which may further expand the market potential for its weight loss drugs.”
