Eli Lilly and CompanyLegal action against unauthorized sellers and engagement with regulators protect its obesity drug portfolio.

Eli Lilly has intensified legal action against U.S. entities accused of selling unauthorized versions of its experimental obesity drug retatrutide. The company is pursuing multiple lawsuits as part of a broader effort to curb black market distribution of the unapproved treatment. Eli Lilly is also engaging regulators and online platforms to address patient safety risks and protect its obesity drug portfolio. The company is guiding to US$85b to US$87b in 2026 revenue, with a heavy tilt toward obesity and diabetes drugs such as Mounjaro, Zepbound and future GLP-1 assets. Investors will be looking for concrete outcomes such as successful court rulings, visible reductions in unauthorized online supply, or clearer FDA and Department of Justice actions that limit compounded or gray market versions of GLP-1s and retatrutide before key Phase 3 and approval milestones.
