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.

The Biden administration announced Friday that Ozempic, Wegovy and 13 additional drugs will now be covered under Medicare Part-D for price negotiations, the next round of negotiations under the Inflation Reduction Act passed by President Joe Biden in 2022.

Blockbuster weight-loss and diabetes drugs Wegovy and Ozempic top the list of 15 drugs selected for the second round of federal price negotiations, which are scheduled to begin this year, with resulting bargained prices going into effect in 2027.
