Aug 9 (Reuters) - Charles River Laboratories International (CRL.N) beat Wall Street estimates for second-quarter results on Wednesday, as the strong demand for contract researcher's tools and services cushioned the impact of suspended non-human primates' (NHP) shipment. The statement comes after Charles River in February suspended the shipment of NHPs from Cambodia as the Department of Justice and U.S. Fish and Wildlife Service investigated the company over smuggling of wild long-tailed macaques to the United States. The Massachusetts-based company tightened its full-year profit forecast to the range of $10.30 to $10.90 per share, compared with $9.90 to $10.90 previously expected. Excluding items, the company earned $2.69 per share in the quarter ended July 1, beating analysts' average estimate of $2.64 per share.
