Just how much Medicare price negotiations will negatively impact Novo Nordisk, though, depends on what the final negotiated prices for Ozempic, Wegovy, and Rybelsus will be. In Medicare's negotiations for 2026, the new prices achieved an average of 22% savings.

Novo Nordisk's blockbuster diabetes drug Ozempic and weight-loss treatment Wegovy are among the 15 drugs targeted for Medicare price negotiations for 2027, the U.S. government said on Friday, part of a law pharmaceutical companies have pledged to revisit with the Trump administration.

The talks on drugs including Novo Nordisk's Wegovy, GSK's Trelegy Ellipta, and Pfizer's Xtandi will set Medicare prices that go into effect in 2027.
