Health-care companies fell as a major alliance in the obesity drug market crumbled.

Shares of Hims & Hers Health plunged by more than 30% after Danish weight-control drug maker Novo Nordisk abruptly pulled out of a partnership with the telehealth firm on the distribution of Wegovy. Novo Nordisk cited Hims' compounding-pharmacy activities and alleged deceptive marketing.

Novo Nordisk shares fell by more than 5% as investors looked askance at the motivation for the sudden about-face.

Rival Eli Lilly gained despite promising data from a clinical trial of Novo Nordisk's next-generation obesity drug.
