By Jacob Gronholt-Pedersen (Reuters) -Shares in Novo Nordisk fell as much as 6% on Friday before recovering some ground later in the session, extending recent losses that threaten to wipe out all the gains since the drugmaker launched its blockbuster weight-loss treatment Wegovy four years ago.

Partially as a result, Novo Nordisk stock has steadily declined since last summer. Over the past year, NVO shares are down more than 57%. And since the beginning of 2025, the company’s share price has declined more than 35%. As of the time of this writing, NVO shares are down just over 20% this morning to $55.17 per share.

Novo Nordisk has named Maziar Mike Doustdar, currently the company’s EVP of international operations, as the new CEO. Doustdar will succeed Lars Fruergaard Jørgensen, whose surprise abdication was announced in May.
