Chipotle Mexican Grill Inc. on Thursday won the dismissal of an investor lawsuit claiming it concealed food safety risks, causing its stock to drop after widely publicized outbreaks of foodborne illnesses in 2014 and 2015.

U.S. District Judge Katherine Polk Failla in Manhattan said that while the outbreaks were cause for concern, the lawsuit failed to support its claim that Chipotle defrauded investors.
