CASE NUMBER 23-cv-11132
JUDGE The Hon. Denise Jefferson Casper
CLASS PERIOD May 5, 2020 and February 21, 2023

Case Background:

A class action lawsuit has been filed on behalf of those who purchased or acquired Charles River Laboratories International, Inc. ("Charles River") (NYSE:  CRL) securities between May 5, 2020 and February 21, 2023, both dates inclusive (the “Class Period”). 

On February 22, 2023, Charles River revealed that the company had received a subpoena from the U.S. Department of Justice relating to an ongoing investigation in conjunction with the U.S. Fish and Wildlife Service into the supply chain and illegal importation of non-human primates for research. On the same day, during an earnings call with investors, James C. Foster, the company’s CEO, stated that the “investigation in current [non-human primate] supply situation will result in study delays in our Safety Assessment business.” He further stated that the investigation into the Cambodian non-human primate chain would reduce the annual revenue forecast by approximately 200 basis points to 400 basis points.
