Novo Nordisk said on Monday it would halt its collaboration with U.S. telehealth company Hims & Hers Health over the distribution of the Danish company's blockbuster Wegovy weight loss drugs. The two companies had announced a collaboration in April for Hims & Hers to sell Wegovy through a bundled offering on the telehealth company's platform.

Hims & Hers stock plunged around 30% on Monday after drugmaker Novo Nordisk abruptly ended a month-long collaboration to make its weight loss drug Wegovy available on the telehealth company's platform.
