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

In fact, Novo Nordisk recently reported positive results for one of its anti-obesity candidates that puts its current best-selling drug in this area, Wegovy, to shame. Let's look deeper into these results and what they could mean for investors.

The Danish maker of Ozempic and Wegovy reported a 25 percent increase in sales to $40.6 billion, but said it expected slower growth this year.

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