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 sells semaglutide as Ozempic and Rybelsus for diabetes and as Wegovy for obesity. In price talks, CMS will treat the different forms as a single product.

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.
