Media statement: NHP supply clarification

As we have previously stated, U.S. NHP studies impact less than 2% of Labcorp’s total enterprise revenue. Our non-U.S. sites do not use Cambodian supply. For U.S. NHP studies, the company has increased the number of NHP vendors with multi-year agreements to secure supply, including U.S.-bred NHP supply. We have included an impact of $80-100 million for our Early Development business in our recent 2023 guidance. We are confident about the steps we have taken to secure NHP supply for this year and beyond.
