The Danish drugmaker, which makes Ozempic and Wegovy, has seen its stock tumble as competition in the weight-loss drug market has grown fiercer.

Wegovy-maker Novo Nordisk ousted CEO Lars Fruergaard Jorgensen on Friday over concerns the company is losing its first-mover advantage in the highly competitive obesity drug market.

FRANKFURT, Germany (AP) — Danish pharmaceutical company Novo Nordisk A/S, maker of blockbuster weight loss drug Wegovy, said Friday its CEO was stepping down by “mutual agreement” with the company’s board of directors, citing “recent market challenges” and a steep decline in the company’s share price.
