The filed complaint alleges that defendants made false statements and/or concealed that: (1) Charles River had engaged in illegal activity with respect to its importation of non-human primates for research; (2) 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) as a result, Charles River would be forced to suspend shipments of primates from Cambodia; and (4) 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.
