Hims & Hers Health reported fourth-quarter results on Monday that beat analysts' expectations, but the stock sank in extended trading.

The ad goes on to tout Hims & Hers' weight loss drugs as less expensive alternatives to medications like Ozempic and Wegovy, which both contain the active ingredient semaglutide and are approved by the U.S. Food and Drug Administration to treat Type 2 diabetes and obesity, respectively.

Hims & Hers said on Monday that it may no longer be able to sell compounded versions of the weight-loss drug made by Novo Nordisk because its pathway to do so closed when the U.S. FDA declared Friday that the drug's shortage was over.

Shares of Hims & Hers Health (HIMS) shares plunged in late trading Monday after the company reported falling margins as costs rose, overshadowing better-than-expected sales. The online healthcare provider’s fourth-quarter revenue nearly doubled year-over-year to $481.
