Charles River Laboratories Announces Second-Quarter 2015 Results from Continuing Operations

– Second-Quarter Revenue of $339.6 Million –

– Second-Quarter GAAP Earnings per Share of $1.02
and Non-GAAP Earnings per Share of $0.96 –

– Updates 2015 Guidance for Celsis Acquisition –

– Renews Strategic Partnership with AstraZeneca –

– Plans to Reopen Shrewsbury, Massachusetts Facility in Early 2016 –

WILMINGTON, Mass.--(BUSINESS WIRE)--July 30, 2015--Charles River Laboratories International, Inc. (NYSE: CRL) today reported its results for the second quarter of 2015. For the quarter, revenue from continuing operations was $339.6 million, a decrease of 0.5% from $341.2 million in the second quarter of 2014. Foreign currency translation reduced reported revenue growth by 6.2%. On a constant-currency basis, revenue growth of 5.7% was driven by both the Discovery and Safety Assessment and Manufacturing Support segments.

On a GAAP basis, net income from continuing operations for the second quarter of 2015 was $49.3 million, or $1.02 per diluted share, compared to $36.5 million, or $0.75 per diluted share, for the second quarter of 2014. The increase was primarily related to a $9.9 million, or $0.21 per diluted share, bargain purchase gain resulting from a small acquisition in the Avian Vaccine business during the second quarter of 2015. The gain was excluded from non-GAAP results.

On a non-GAAP basis, net income from continuing operations was $45.8 million for the second quarter of 2015, a decrease of 1.1% from $46.3 million for the same period in 2014. Second-quarter diluted earnings per share on a non-GAAP basis were $0.96, including a $0.01 loss from limited partnership investments. This result compared to $0.97 in the second quarter of 2014, which included a $0.03 gain from limited partnership investments. In addition, foreign currency translation reduced earnings per share by approximately $0.03 in the second quarter of 2015.

James C. Foster, Chairman, President and Chief Executive Officer, said, “We were very pleased with our second-quarter performance. Continued strong revenue growth for our Safety Assessment and Endotoxin and Microbial Detection businesses, coupled with stabilization of our research model business in North America and Europe, were the primary drivers of the 5.7% constant-currency revenue increase, and a 6% sequential revenue increase. Higher sales and operating efficiencies enabled us to achieve a 20% non-GAAP operating margin for the first time since 2008.”

“The second quarter also marked two notable developments: We renewed our successful strategic partnership with AstraZeneca for an additional five years, and made the decision to reopen our facility in Shrewsbury, Massachusetts. Both events are a testament to the confidence that clients place on our scientific expertise and the value of our focused, early-stage drug research portfolio.”

“Primarily as a result of the acquisition of Celsis, which closed on July 24, we are increasing our constant-currency revenue guidance for 2015 to a range of 8.0% to 9.5%, and our non-GAAP earnings per share guidance to a range of $3.60 to $3.70.”

Second-Quarter Segment Results

Research Models and Services (RMS)

Revenue for the RMS segment was $120.0 million in the second quarter of 2015, a decrease of 9.8% from $133.1 million in the second quarter of 2014. Foreign currency translation reduced reported revenue growth by 7.3%. On a constant-currency basis, revenue declined by 2.5%. Higher sales of research models were offset by lower revenue for the Genetically Engineered Models and Services (GEMS) business.

In the second quarter of 2015, the RMS segment’s GAAP operating margin was 27.9% compared to 25.7% in the second quarter of 2014. On a non-GAAP basis, the operating margin increased slightly to 29.1% from 29.0% in the second quarter of 2014.

Discovery and Safety Assessment (DSA)

Revenue from continuing operations for the DSA segment was $153.4 million in the second quarter of 2015, an increase of 7.5% from $142.6 million in the second quarter of 2014. Foreign currency translation reduced reported revenue growth by 3.9%. On a constant-currency basis, revenue growth of 11.4% was driven primarily by the Company’s Safety Assessment business, which generated a third consecutive quarter of low-double-digit revenue growth, with study volume, market share gains, and pricing as the primary contributors. This growth was offset in part by Argenta and BioFocus, which reported lower sales as a result of the early termination of a large contract for an integrated chemistry program. The ChanTest acquisition, which was completed on October 29, 2014, contributed 2.8% to DSA revenue growth in the second quarter. Sales to mid-tier biotechnology clients continued to be robust.

In the second quarter of 2015, the DSA segment’s GAAP operating margin was 18.4% compared to 12.5% in the second quarter of 2014. On a non-GAAP basis, the operating margin increased to 21.6% from 17.1% in the second quarter of 2014. The non-GAAP operating margin improvement was driven by higher capacity utilization and pricing for safety assessment services, as well as a foreign exchange benefit due to a weaker Canadian dollar.

Manufacturing Support (Manufacturing)

Revenue for the Manufacturing segment was $66.2 million in the second quarter of 2015, an increase of 1.1% from $65.4 million in the second quarter of 2014. Foreign currency translation reduced reported revenue growth by 8.7%. On a constant-currency basis, revenue growth was 9.8%. The Endotoxin and Microbial Detection (EMD) business, which achieved constant-currency revenue growth of approximately 10% in the second quarter, was the primary driver of the revenue increase. The Avian Vaccine acquisition contributed 1.7% to the Manufacturing segment’s second-quarter revenue growth.

In the second quarter of 2015, the Manufacturing segment’s GAAP operating margin was 30.9% compared to 31.3% in the second quarter of 2014. On a non-GAAP basis, the operating margin increased to 33.6% from 33.4% in the second quarter of 2014. Benefits from higher sales volume were largely offset by foreign exchange, which negatively impacted the segment operating margin because the EMD business manufactures products in the United States and distributes these products internationally, with the resulting revenue recorded in local currencies.

Stock Repurchase Update

During the second quarter of 2015, the Company repurchased approximately 550,000 shares for a total of $40.8 million. As of June 27, 2015, the Company had $87.6 million remaining on its stock repurchase authorization.

Renews Strategic Partnership with AstraZeneca

In the second quarter, Charles River extended its initial three-year strategic partnership with AstraZeneca for an additional five-year period. Under the agreement, which extends into 2020, Charles River retains its position as AstraZeneca’s preferred strategic partner for outsourced regulated safety assessment and development DMPK (drug metabolism and pharmacokinetics).

Plans to Reopen Massachusetts Facility in Early 2016

Based on considerable client indications of interest, and a comprehensive evaluation of the opportunities, the Company has made the decision to reopen its facility in Shrewsbury, Massachusetts, in early 2016. Initially, we expect to open a portion of the facility and offer only non-GLP services. Validation and staffing for GLP services will follow at a later date, depending on demand.

The Massachusetts facility will provide needed capacity to accommodate increasing demand for our Discovery and Safety Assessment services from large biopharmaceutical and emerging biotechnology companies, as well as academic research institutions in the Boston-Cambridge biohub, one of the largest concentrations of medical research in the world.

Updates 2015 Guidance

The Company is updating its forward-looking guidance based on continuing operations for 2015.

Primarily due to the acquisition of Celsis, revenue growth is now expected to be 8.0% to 9.5% on a constant-currency basis, compared to the prior range of 6.5% to 8.0%. Based on current rates, the Company expects foreign currency translation will reduce revenue growth by slightly more than 5.0%, which would result in reported revenue growth of 3.0% to 4.5%. The Company previously estimated a 5.5% impact from foreign currency translation and reported revenue growth of 1.0% to 2.5%.

Guidance for non-GAAP earnings per share in 2015 has been increased to reflect the Celsis acquisition, and GAAP earnings per share guidance has been increased due primarily to the bargain purchase gain associated with the Avian Vaccine acquisition.

Foreign currency translation is now expected to reduce earnings per share by approximately $0.10 in 2015, compared to the Company’s previous estimate of $0.17 per share. The improvement in foreign currency is being offset in part by lower expectations for Argenta and BioFocus.

The Company’s updated earnings per share guidance is as follows:

(1) Amortization of intangibles assets excludes the impact of the Celsis acquisition because the preliminary purchase price allocation has not been completed.

(2) These costs relate primarily to the Company’s Shrewsbury, Massachusetts, facility.

(3) These charges relate primarily to the Company’s planned efficiency initiatives in 2015, including site consolidation costs, asset impairments, and severance. Other projects in support of the global productivity and efficiency initiatives are expected, but these charges reflect only the decisions that have already been finalized. These charges also include executive transition costs.

(4) These adjustments are related to the evaluation and integration of acquisitions, which primarily include transaction, third-party integration, and certain compensation costs, and fair value adjustments associated with contingent consideration.

Non-GAAP Reconciliations/Discontinued Operations

The Company reports non-GAAP results in this press release, which exclude certain items that are outside of normal operations. A reconciliation of GAAP to non-GAAP results is provided in the schedules at the end of this press release. In addition, the Company reports results from continuing operations, which exclude results of the Phase I clinical business that was divested in 2011. The Phase I business is reported as a discontinued operation.

Use of Non-GAAP Financial Measures

This press release contains non-GAAP financial measures, such as non-GAAP earnings per diluted share, which exclude the amortization of intangible assets and other charges related to our acquisitions; expenses associated with evaluating and integrating acquisitions, as well as fair value adjustments associated with contingent consideration; charges, gains and losses attributable to businesses or properties we plan to close, consolidate or divest; the gain related to the bargain purchase of Sunrise Farms; severance and other costs associated with our efficiency initiatives; executive transition costs; accelerated depreciation charges related to the consolidation of research model production operations; a reversal of indemnification assets associated with acquisitions and corresponding interest; and costs related to a U.S. government billing adjustment and related expenses. We exclude these items from the non-GAAP financial measures because they are outside our normal operations. This press release also refers to our revenue in both a GAAP and non-GAAP (constant currency) basis. There are limitations in using non-GAAP financial measures, as they are not prepared in accordance with generally accepted accounting principles, and may be different than non-GAAP financial measures used by other companies. In particular, we believe that the inclusion of supplementary non-GAAP financial measures in this press release helps investors to gain a meaningful understanding of our core operating results and future prospects without the effect of these often-one-time charges, and is consistent with how management measures and forecasts the Company's performance, especially when comparing such results to prior periods or forecasts. We believe that the financial impact of our acquisitions (and in certain cases, the evaluation of such acquisitions, whether or not ultimately consummated) is often large relative to our overall financial performance, which can adversely affect the comparability of our results on a period-to-period basis. In addition, certain activities such as business acquisitions, happen infrequently and the underlying costs associated with such activities do not recur on a regular basis. Presenting revenue on a constant-currency basis allows investors to measure our revenue growth exclusive of foreign currency exchange fluctuations more clearly. Non-GAAP results also allow investors to compare the Company’s operations against the financial results of other companies in the industry who similarly provide non-GAAP results. The non-GAAP financial measures included in this press release are not meant to be considered superior to or a substitute for results of operations prepared in accordance with GAAP. The Company intends to continue to assess the potential value of reporting non-GAAP results consistent with applicable rules and regulations. Reconciliations of the non-GAAP financial measures used in this press release to the most directly comparable GAAP financial measures are set forth in this press release, and can also be found on the Company’s website at ir.criver.com.

Caution Concerning Forward-Looking Statements

This press release includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “anticipate,” “believe,” “expect,” “intend,” “will,” “may,” “estimate,” “plan,” “outlook,” and “project,” and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These statements also include statements regarding our projected future financial performance including revenue (on both a reported and constant-currency basis), operating margins, earnings per share, the expected impact of foreign exchange rates, and the expected benefit of our limited partnership investments; the future demand for drug discovery and development products and services, including our expectations for future revenue trends; our plans to reopen the facility in Shrewsbury, Massachusetts; our expectations with respect to the impact of acquisitions on the Company, our service offerings, strategic relationships, revenue, revenue growth rates, and earnings; the development and performance of our services and products; market and industry conditions including the outsourcing of services and spending trends by our clients; the potential outcome of and impact to our business and financial operations due to litigation and legal proceedings, including with respect to our ongoing investigation of inaccurate billing with respect to certain government contracts; and Charles River’s future performance as delineated in our forward-looking guidance, and particularly our expectations with respect to revenue, the impact of foreign exchange, and enhanced efficiency initiatives. Forward-looking statements are based on Charles River’s current expectations and beliefs, and involve a number of risks and uncertainties that are difficult to predict and that could cause actual results to differ materially from those stated or implied by the forward-looking statements. Those risks and uncertainties include, but are not limited to: the ability to successfully integrate businesses we acquire; the ability to execute our efficiency initiatives on an effective and timely basis (including divestitures and site closures); the timing and magnitude of our share repurchases; negative trends in research and development spending, negative trends in the level of outsourced services, or other cost reduction actions by our clients; the ability to convert backlog to revenue; special interest groups; contaminations; industry trends; new displacement technologies; USDA and FDA regulations; changes in law; continued availability of products and supplies; loss of key personnel; interest rate and foreign currency exchange rate fluctuations; changes in tax regulation and laws; changes in generally accepted accounting principles; and any changes in business, political, or economic conditions due to the threat of future terrorist activity in the U.S. and other parts of the world, and related U.S. military action overseas. A further description of these risks, uncertainties, and other matters can be found in the Risk Factors detailed in Charles River's Annual Report on Form 10-K as filed on February 17, 2015, as well as other filings we make with the Securities and Exchange Commission.
