Kaplan Fox Notifies Investors of Complaint Filed Against Charles River Laboratories International, Inc.

New York, NY – A complaint was filed against Charles River Laboratories International, Inc. alleging the company and its executives concealed illegal importation of nonhuman primates used for research. The complaint was filed in Massachusetts federal court against Charles River, James Foster, David Smith and Flavia Pease. This is a class action on behalf of persons and entities that purchased or otherwise acquired Charles River securities between May 5, 2020 and February 21, 2023, inclusive (the Class Period).

The Complaint states, “Charles River is a full-service, non-clinical global drug development partner with a mission to create healthier lives. The Company has three reporting segments: Research Models and Services, Discovery and Safety Assessment, and Manufacturing Solutions. The Discovery and Safety Assessment segment accounts for approximately 60% of the Company’s total revenue and offers, among other things, safety assessment studies required for regulatory submission of therapeutic solutions.”

The Complaint goes on to allege, “On February 22, 2023, before the market opened, Charles River revealed that it had received a subpoena from the U.S. Department of Justice (“DOJ”) relating to an ongoing investigation in conjunction with the U.S. Fish and Wildlife Service (“USFWS”) into the supply chain and illegal importation of non-human primates for research. The Company noted that it was voluntarily suspending shipments of primates from Cambodia, which would negatively impact its earnings for the year and would reduce revenue growth by 200 basis points to 400 basis points.”
