The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) that Charles River had engaged in illegal activity with respect to its importation of non-human primates for research; (2) that, as a result, Charles River was at a heightened risk of criminal and regulatory investigation by, inter alia, the U.S. Department of Justice; (3) that, as a result, Charles River would be forced to suspend shipments of primates from Cambodia; and (4) that, as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.
