Marijuana producer Aurora Cannabis was hit with a shareholder class action lawsuit in New Jersey federal court Thursday after analysts were caught off guard by plummeting sales.

The Canadian company, which began trading on the New York Stock Exchange in October 2018, has operations in 24 countries. Aurora and Coca-Cola announced in September that they were studying the market for cannabis-infused beverages. But on Nov. 14 Aurora said its sales had fallen 25% and marijuana sales to consumers fell 33% in the three months ending on Sept. 30.
