Exhibit 99.1 Charles River Laboratories Announces First-Quarter 2006 Results; Enters into Agreement to Sell Phase II - IV Clinical Business to Kendle; Provides Revised Guidance for 2006; Increases Stock Repurchase Authorization WILMINGTON, Mass.--(BUSINESS WIRE)--May 9, 2006--Charles River Laboratories International, Inc. (NYSE: CRL) today reported first-quarter 2006 financial results and announced that it has entered into a definitive agreement with Kendle International Inc. (Nasdaq: KNDL) to sell its Phase II - IV Clinical Services business, as it realigns its portfolio to focus on its core drug discovery and development strengths. In conjunction with the planned portfolio realignment, the Company recorded a goodwill impairment charge of $129.2 million, or $1.81 per share, for the Phase II - IV Clinical business in the first quarter of 2006. As a result, the Company reported a net loss per share of $1.40 for the first quarter of 2006, on sales of $283.8 million. On a non-GAAP basis, earnings per share were $0.50, which excludes the impairment charge and amortization and compensation charges related to the Inveresk acquisition. Further actions announced by the Company today included strategic initiatives targeted at streamlining the business infrastructure and improving operating efficiency, an increase of its stock repurchase authorization to $300 million and revised annual guidance for 2006. James C. Foster, Chairman, President and Chief Executive Officer said, "In keeping with our goal to capitalize on our core competencies and to focus on internal process improvement, we are realigning our business through the sale of the Phase II - IV portion of our Clinical Services business. In addition, we will be closing our Interventional and Surgical Services (ISS) facility in Massachusetts. These actions will allow us to focus our financial and operating resources on our core Research Models and Services, Preclinical Services and Clinical Phase I businesses, which we believe offer significant long-term growth opportunities. We believe that the market for outsourced preclinical services, particularly toxicology, continues to be strong, and we see emerging opportunities in In Vitro products, preconditioning services for research models, and early-stage clinical trials. We have concluded these businesses offer us the most promising opportunities for growth, and support our long-term goals of sales growth of 11% to 12%, earnings per share growth of 14% to 15%, an operating margin of 25%, strong cash flow generation, and steadily improving returns on invested capital." Mr. Foster said that sales growth from continuing operations for 2006 would be revised to a range of 6% to 8%, due primarily to continuing softness in Transgenic Services, flat Vaccine sales and Preclinical Services capacity constraints. The year-over-year growth rate is based on pro forma sales of approximately $990 million in 2005, which excludes sales from the Phase II - IV Clinical and ISS businesses. As a result of lower sales, partially offset by expected benefits from the strategic initiatives, and including the goodwill impairment charge, the Company now expects the 2006 GAAP net loss per share from continuing operations, which excludes the results of its Phase II-IV Clinical and ISS businesses, will be in a range of $0.09 to $0.15. Non-GAAP earnings per share, which exclude the charge for goodwill impairment, the cost of the strategic initiatives, and amortization and stock compensation charges related to the Inveresk acquisition, are expected to be in a range of $2.12 to $2.18. Divestiture of Phase II - IV Clinical Business As a result of an evaluation of its strategic goals, the Company determined that the Phase II - IV Clinical Services business, at its current scale, while profitable, does not take advantage of the Company's core competencies, and believes that monetizing the Phase II - - IV clinical assets and redeploying the resulting cash would be more beneficial to the long-term business, to customers and to shareholders. On May 9, 2006, the Company entered into a definitive agreement to sell the Phase II - IV Clinical business to Kendle International Inc. for $215 million in cash. Kendle is a global clinical research organization that generated over $200 million in net service revenues in 2005. By combining the Company's Phase II-IV business with its own, Kendle will significantly enhance its ability to conduct large-scale multinational clinical studies. The transaction, which the Company expects to close in the third quarter of 2006, is subject to regulatory approvals and other customary conditions. Credit Suisse acted as financial advisor to the Company. As a result of the pending sale of the Phase II - IV business, the Company assessed the goodwill assigned to its Clinical segment, and based on management's estimates of fair value, which includes the projected sales price, determined that an impairment existed. As a result, a charge of $129.2 million, or $1.81 per share, was recorded in the first quarter of 2006 for the impairment of goodwill. The Company has determined that the Phase I Clinical Services business is an essential, strategic component of its service offerings, as it enables us to support customers' preclinical efforts through early-stage clinical trials. The Company will retain the Phase I facility in Edinburgh, Scotland, and is continuing to assess options for a Phase I presence in North America. Beginning in the second quarter of 2006, the Company anticipates that the Phase I financial results will be included in the Preclinical Services business segment. First-Quarter 2006 Results Net sales for the first quarter of 2006 increased to $283.8 million compared to $273.7 million reported in the first quarter of 2005, a gain of 3.7%, or 6.7% excluding the negative effect of foreign exchange. Strong sales of toxicology services, research models in North American and Europe, and In Vitro products drove the first-quarter sales increase. On a GAAP basis, which includes the impairment charge, the Company reported a net loss of $100.1 million, or $1.40 per diluted share, in the first quarter of 2006, compared to net income of $27.6 million, or $0.40 per diluted share, in the first quarter of 2005. In addition to the impairment charge, first-quarter 2006 results included $3.6 million of stock option expense recognized in accordance with Statement of Financial Accounting Standard No. 123R (SFAS 123R), "Share-Based Payments," which the Company adopted on January 1, 2006. In accordance with SFAS 123R, stock compensation expense was recorded in the business segment results and in unallocated corporate overheard. Had SFAS 123R been adopted in 2005, first-quarter 2005 results would have included $6.0 million of stock option expense. On a non-GAAP basis, net income was $36.4 million, or $0.50 per diluted share, in the first quarter of 2006, compared to $38.6 million, or $0.55 per diluted share, in the first quarter of 2005. Non-GAAP results in the first quarter of both years exclude amortization and stock-based compensation charges related to the acquisition of Inveresk. These charges amounted to $10.9 million, or $0.10 per share, in the first quarter of 2006 and $16.3 million, or $0.15 per share, in the first quarter of 2005. In addition, first-quarter 2006 non-GAAP results exclude the goodwill impairment charge of $129.2 million, or $1.81 per share. Business Segments Results Research Models and Services (RMS) First-quarter 2006 net sales for the RMS segment of the business were $129.0 million, compared to $127.9 million in the first quarter of 2005, an increase of approximately 1.0%. When excluding the negative effect of foreign exchange, the growth rate was 4.7%. As was the case in the second half of 2005, growth was driven by North America Research Model sales and In Vitro products and services. European Research Models sales also showed improvement in the first quarter of 2006 compared to the same period last year, benefiting from higher pharmaceutical and biotechnology customers' spending. First-quarter sales growth was partially offset by the effect of foreign exchange on sales, mainly in Japan, a continuing decline in the U.S. Transgenic Services businesses, and lower sales of vaccine products due to avian influenza. In addition, sales of large animals were below the first quarter of last year due to timing of shipments. Primarily as a result of lower sales and $1.4 million of stock compensation expense, the gross margin declined to 43.3% from 44.2% reported in the first quarter of 2005. The first-quarter operating income was $40.5 million and the operating margin was 31.4%, down from $42.3 million and 33.1% in the same period last year. Preclinical Services Net sales for the Preclinical Services segment were $122.5 million in the first quarter of 2006, an increase of 7.4% from the $114.1 million reported in the first quarter of 2005. Excluding the negative effect of foreign exchange, the first-quarter growth rate was 9.1%. The sales increase was due to continuing strong demand for outsourced toxicology services, partially offset by negative foreign exchange, capacity constraints, lower sales of discovery services (which include metabolism, pharmacokinetics and pharmacology) and ISS, and study delays in our Pennsylvania facility. These issues negatively affected the gross and operating margins, as did $1.9 million of stock compensation expense and increased operating costs in the Company's Montreal operation. Montreal's cost structure has increased as a result of rapid expansion and the associated hiring, and its results were further affected by the unfavorable impact of foreign exchange. To improve operating efficiency in Montreal, the Company has implemented headcount reductions in administrative and support areas. As a result of these actions and the impending closure of ISS Massachusetts, the Company expects margins to improve beginning in the second quarter of 2006. The segment's gross margin was 30.3% compared to 33.5% in the first quarter of 2005. Operating income was $12.1 million in the first quarter of 2006, compared to $12.5 million in the first quarter of last year. The operating margin was 9.9% compared to 11.0% in the first quarter of 2005. When excluding amortization related to the Inveresk acquisition, first-quarter non-GAAP operating income was $20.2 million and the non-GAAP operating margin was 16.5%, compared to non-GAAP operating income of $22.8 million and an operating margin of 20.0% in the first quarter of 2005. The decline in gross and operating margins was due primarily to SFAS 123R costs of $1.9 million, ISS, study delays, and the cost structure in Montreal. Clinical Services For the first quarter of 2006, net sales for the Clinical Services segment were $32.3 million compared to $31.7 million in the first quarter of 2005, an increase of 1.9%. Excluding the negative effect of foreign exchange, the sales growth rate was 6.3%. The Phase I clinic had very strong sales in the quarter, as the effect of the European Clinical Trials Directive waned and targeted sales efforts brought new clients from Europe and Japan to the clinic. Higher sales and continued efforts to optimize the cost structure resulted in a gross margin of 31.6% compared to 31.0% in the first quarter of 2005. Including the goodwill impairment charge of $129.2 million, the segment's operating loss was $127.4 million in the first quarter of 2006, compared to operating income of $0.8 million in the first quarter of last year. When excluding the impairment charge and amortization related to the Inveresk acquisition, first-quarter non-GAAP operating income was $4.2 million and the non-GAAP operating margin was 13.1%, compared to non-GAAP operating income of $3.8 million and an operating margin of 12.1% in the first quarter of 2005. The GAAP and non-GAAP margin increases were due primarily to improved operating efficiency, partially offset by allocation of $0.2 million of stock compensation expense. Backlog The backlog for Preclinical and Clinical Services at April 1, 2006, was $481 million compared to $427 million at the end of the first quarter of 2005 and $448 million at the end of the fourth quarter of 2005. Net bookings increased 35.9% to $190 million and the net book-to-bill ratio rose to 1.23 from 0.96 in the first quarter of 2005. Once the Phase II - IV Clinical Services business has been divested, the Company will no longer report quarterly backlog. The Company does not report backlog for the RMS business segment because turnaround time from placement to completion of orders, both for products and services, is rapid, and the characteristics of the Preclinical Services business are similar. Strategic Initiatives The Company is implementing a number of actions designed to improve operating efficiency and profitability during the remainder of 2006. The total cost of these initiatives is expected to be $7.2 million, or $0.07 per diluted share. The benefit associated with these actions is expected to be $16.0 million, or $0.16 per diluted share, in 2006, with additional savings in later years. The Company expects to record the charges in the second quarter of 2006. Commenting on these actions, Mr. Foster said, "We continue to identify and implement actions to improve our operating profitability, while maintaining our high standards of customer service and responsiveness. We do not see the two goals as mutually exclusive and in fact, our 4th Generation Six Sigma(TM) initiative has helped us to identify opportunities to enhance operations at a lower cost." RMS initiatives are focused primarily on the closure of two remote sites in the Vaccine businesses. These are smaller, satellite facilities which are inefficient to operate. In addition, the Company will continue its efforts to right-size the Transgenic Services business to address the existing market opportunity through headcount reductions and a management consolidation. The cost of these actions is expected to be approximately $2.0 million, or $0.02 per diluted share. Preclinical Services initiatives include the closure of ISS Massachusetts, as well as a small operating unit in Ireland which provides similar services. The ISS facility will wind down operations and is expected to close in late 2006. The second-quarter charge related to these anticipated closures is expected to be $3.2 million, or $0.03 per diluted share. In addition, the Company expects to record a charge of $2.0 million, or $0.02 per diluted shares, for headcount reductions in Montreal and Massachusetts. To further support the Company's goal of operating efficiency, cost savings initiatives have been implemented at the corporate level. There will be no charges associated with these actions, which include selective headcount freezes and adjustment of equity and incentive compensation. Mr. Foster continued, "With a realigned portfolio of high-end, essential products and services and a leaner cost structure, we expect to enhance our ability to support our customers in their pursuit of drug discovery and development to improve human and animal health. We are making significant investments across the spectrum of our business, from production capacity and preconditioning services and the PTS in our RMS segment, through our entire Preclinical Services business. We believe that these investments, all of which leverage our core competencies of veterinary medicine and regulatory preclinical services, support our goal to build a larger, more profitable business. 2006 Revised Guidance The following forward-looking guidance is based on continuing operations, which exclude the Phase II - IV Clinical and ISS businesses. Beginning in the second quarter of 2006, the Company expects to report the Phase II - IV and ISS businesses as discontinued operations, which will result in $0.15 dilution to the Company's original 2006 earnings guidance. This guidance also assumes implementation on January 1, 2006, of SFAS 123R, and therefore includes an estimated $0.12 of stock option expense. Guidance is based on current foreign exchange rates. The Company is revising its estimates for 2006 sales growth and earnings per share from continuing operations. Net sales growth for 2006 from continuing operations is expected to be in a range of 6% to 8%, based on lower-than-expected first-quarter results. Due primarily to the $1.81 per share goodwill impairment charge and the first-quarter shortfall of $0.07 per share, the Company estimates that on a GAAP basis, it will report a net loss for 2006 in a range of $0.09 to $0.15. Non-GAAP earnings per share, which exclude the goodwill impairment charge, $0.39 per share of amortization and compensation charges related to the acquisition of Inveresk, and the $0.07 per share second-quarter charge associated with the strategic initiatives, are expected to be in a range of $2.12 to $2.18. The Company is committed to improving its operating efficiency, and the anticipated benefit of the strategic initiatives announced today is expected to significantly improve operating results in the balance of the year. The $0.16 per share benefit from the strategic initiatives is included in the revised earnings per share estimates.
