Ozempic and Wegovy maker Novo Nordisk quieted Wall Street's concerns with its fourth-quarter results and 2025 outlook.

The drugmaker expects the regulator to remove Wegovy and Ozempic from its shortage list, blocking other companies from legally selling cheap knockoff versions.

One of Novo Nordisk's next-generation obesity shots to follow up on the success of Wegovy helped patients lose 22% of their weight in 36 weeks, according to early-stage trial results on Friday, boosting the drugmaker's shares.

Investors are upset at a lack of clarity over the results of Wegovy successor CagriSema after trials published in December.
