WILMINGTON, Mass.--(BUSINESS WIRE)--Jan. 7, 2002--Charles River Laboratories International, Inc. (NYSE: CRL - news) announced today that it is raising its previous guidance on estimated earnings per share performance for the recently completed fourth quarter. The Company estimates fourth quarter 2001 earnings per fully diluted share (EPS) of $0.24, including a $0.02 charge for the consolidation of services capabilities related to acquisitions. This estimate compares to the Company's guidance of October 31, 2001 of $0.22 to $0.23 for EPS, including the consolidation charge then estimated to be $0.01. This updated EPS guidance exceeds the consensus First Call estimate of $0.23. The Company also expects fourth quarter sales of approximately $125 million, exceeding the Company's earlier guidance range of $117 million to $120 million. For the full year 2001, the Company estimates revenues of approximately $465 million, and EPS of $0.92, including the $0.02 fourth quarter consolidation charge. These fourth quarter 2001 estimates represent more than 50% revenue growth over the prior year, and more than 100% EPS growth.

James C. Foster, CEO, commented: ``With the fourth quarter now complete, we're pleased to once again see better than anticipated revenue and earnings growth in most of our product lines and services offerings. Our two new acquisitions have again exceeded our expectations, and our research model segment continues to be a strong contributor to earnings and cash flow. Our drug discovery and development services segment continues to experience excellent growth, and solid profitability. We believe that the positive trends in our markets and within our businesses will continue in 2002, with continued strong growth in both revenues and earnings. Our current target for reported EPS in 2002 is in the range of $1.15 to $1.18, or approaching 25% growth. This estimate includes the favorable impact on EPS of accounting changes related to amortization of goodwill, offset in part by a decrease in pension plan returns. We anticipate our reported revenue growth in 2002 to be consistent with our long-term strategic goal of 15%.''

The Company's estimates are before extraordinary items, based on current exchange rates, and subject to the qualifications on ``forward looking'' guidance set forth below.
