CHARLES RIVER LABORATORIES ANNOUNCES
THIRD-QUARTER 2024 RESULTS

– Third-Quarter GAAP Earnings per Share of $1.33
and Non-GAAP Earnings per Share of $2.59 –

WILMINGTON, MA, November 6, 2024 – Charles River Laboratories International, Inc. (NYSE: CRL) today reported its results for the third quarter of 2024. For the quarter, revenue was $1.01 billion, a decrease of 1.6% from $1.03 billion in the third quarter of 2023.

The impact of foreign currency translation benefited reported revenue by 0.4%, and an acquisition contributed 0.9% to consolidated third-quarter revenue. A divestiture of a small Safety Assessment site reduced reported revenue by 0.2%. Excluding the effect of these items, revenue declined 2.7% on an organic basis. On a segment basis, organic revenue growth in the Manufacturing Solutions (Manufacturing) and Research Models and Services (RMS) segments were more than offset by lower revenue in the Discovery and Safety Assessment (DSA) segment.

In the third quarter of 2024, the GAAP operating margin decreased to 11.6% from 14.8% in the third quarter of 2023. This GAAP decrease was primarily driven by costs associated with the Company’s restructuring initiatives. On a non-GAAP basis, the operating margin improved in all three segments; however, the improvements were more than offset by higher unallocated corporate costs, which resulted in the third-quarter operating margin decreasing to 19.9% from 20.5%.

On a GAAP basis, third-quarter net income attributable to common shareholders was $68.7 million, a decrease of 21.4% from $87.4 million for the same period in 2023. Third-quarter diluted earnings per share on a GAAP basis were $1.33, a decrease of 21.3% from $1.69 for the third quarter of 2023. The GAAP net income and earnings per share decreases were driven primarily by lower revenue and operating income, which included higher costs associated with the Company’s restructuring initiatives. On a non-GAAP basis, net income was $133.7 million for the third quarter of 2024, a decrease of 4.8% from $140.5 million for the same period in 2023. Third-quarter diluted earnings per share on a non-GAAP basis were $2.59, a decrease of 4.8% from $2.72 per share for the third quarter of 2023. The decreases in non-GAAP net income and earnings per share were driven primarily by lower revenue and operating income.

James C. Foster, Chair, President and Chief Executive Officer, said, “Forward-looking demand indicators were relatively stable in the third quarter, contributing to third-quarter financial performance which exceeded our prior outlook. We are continuing to navigate through a challenging period as global biopharmaceutical clients reduce spending in conjunction with major restructuring and pipeline reprioritization activities, but overall demand trends do not appear to have deteriorated further. In addition, biotech funding has improved in 2024, and demand appears to be demonstrating early signs of stabilization. These factors resulted in a slight, sequential improvement in net book-to-bill and the cancellation rate in the Safety Assessment business.”

“We remain laser focused during this period on our strategy, which includes aggressively managing our cost structure, enhancing our clients’ experiences to gain additional share, and protecting shareholder value. We will continue to distinguish ourselves through our exceptional science and preclinical focus, in order to extend our leading position as our clients’ preferred, global, non-clinical drug development partner. We expect to emerge from this period as a stronger, leaner, and more profitable company, and an even more responsive partner for our clients,” Mr. Foster concluded.

Revenue for the RMS segment was $197.8 million in the third quarter of 2024, an increase of 5.9% from $186.8 million in the third quarter of 2023. The Noveprim acquisition in November 2023 contributed 4.9% to third-quarter RMS reported revenue, and the impact of foreign currency translation increased revenue by 0.4%. Organic revenue increased by 0.6%, due primarily to higher sales of small research models in all geographic regions, principally driven by higher pricing. This was largely offset by a revenue decline for research model services, particularly in the Insourcing Solutions business.

In the third quarter of 2024, the RMS segment’s GAAP operating margin decreased to 13.9% from 15.2% in the third quarter of 2023. The GAAP operating margin decline was driven primarily by higher amortization expense related to the Noveprim acquisition coupled with higher costs associated with the Company’s restructuring initiatives, including severance and site consolidation costs. On a non-GAAP basis, the operating margin increased to 21.0% from 18.9%. The non-GAAP operating margin increase was primarily driven by higher pricing for small research models, a favorable revenue mix related to the Noveprim acquisition, and the benefit of cost savings associated with the Company's restructuring initiatives.

Revenue for the DSA segment was $615.1 million in the third quarter of 2024, a decrease of 7.4% from $664.0 million in the third quarter of 2023. The divestiture of a small Safety Assessment site reduced reported revenue by 0.3% and the impact of foreign currency translation increased DSA revenue by 0.3%. Organic revenue decreased by 7.4%, driven primarily by lower sales volume in both the Discovery Services and Safety Assessment businesses.

In the third quarter of 2024, the DSA segment’s GAAP operating margin decreased to 20.6% from 22.1% in the third quarter of 2023 primarily driven by lower revenue and higher severance costs related to restructuring initiatives. On a non-GAAP basis, the operating margin increased to 27.4% from 27.2% in the third quarter of 2023. The non-GAAP operating margin increase was primarily driven by the benefit of cost savings associated with restructuring initiatives.

Revenue for the Manufacturing segment was $196.9 million in the third quarter of 2024, an increase of 12.0% from $175.7 million in the third quarter of 2023. The impact of foreign currency translation increased Manufacturing revenue by 0.2%. Organic revenue growth of 11.8% reflected higher revenue across each of the segment’s businesses.

In the third quarter of 2024, the Manufacturing segment’s GAAP operating margin increased to 20.4% from 15.0% in the third quarter of 2023, and on a non-GAAP basis, the operating margin increased to 28.7%, from 24.5% in the third quarter of 2023. The GAAP and non-GAAP operating margin increases were driven primarily by improved operating leverage from higher revenue in each of segment’s businesses, as well as the benefit of cost savings associated with restructuring initiatives.

On August 2, 2024, the Company’s Board of Directors approved a new stock repurchase authorization of $1.0 billion. Following the new authorization, the Company repurchased 500,000 shares during the third quarter of 2024 for a total of $100.7 million. As of September 28, 2024, the Company has $899.3 million remaining on its $1.0 billion stock repurchase authorization.

The Company is updating its financial guidance for 2024, which was previously revised on August 7, 2024. Revenue and non-GAAP earnings per share guidance have been narrowed and slightly raised from the midpoint of the previous ranges to principally reflect the third-quarter financial performance, which exceeded the Company's prior outlook. In addition, GAAP earnings per share guidance has been reduced due primarily to increased charges related to the Company's additional restructuring actions.

The Company’s 2024 guidance for revenue growth and earnings per share is as follows:

Footnotes to Guidance Table:

(1) Organic revenue growth is defined as reported revenue growth adjusted for completed acquisitions and divestitures, as well as foreign currency translation.

(2) These adjustments include amortization related to intangible assets, as well as the purchase accounting step-up on inventory and certain long-term biological assets.

(3) These adjustments are related to the evaluation and integration of acquisitions and divestitures, and primarily include transaction, advisory, certain third-party integration, and related costs; as well as fair value adjustments associated with contingent consideration arrangements.

(4) These adjustments primarily include site consolidation (including site transition costs), severance, impairment, and other costs related to the Company’s restructuring actions.

(5) Certain venture capital and other strategic investment performance only includes recognized gains or losses on certain investments. The Company does not forecast the future performance of these investments.

(6) This item primarily relates to incremental dividends attributable to Noveprim noncontrolling interest holders who have and may continue to receive preferential dividends for fiscal year 2024.

(7) These items primarily relate to (i) certain third-party legal costs related to investigations by the U.S. government into the NHP supply chain related to our Safety Assessment business; and (ii) charges associated with U.S. and international tax legislation that necessitated changes to the Company’s international financing structure.

Charles River has scheduled a live webcast on Wednesday, November 6th, at 9:30 a.m. ET to discuss matters relating to this press release. To participate, please go to ir.criver.com and select the webcast link. You can also find the associated slide presentation and reconciliations of GAAP financial measures to non-GAAP financial measures on the website.

The Company reports non-GAAP results in this press release, which exclude often-one-time charges and other 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.

This press release contains non-GAAP financial measures, such as non-GAAP earnings per diluted share, non-GAAP operating income, non-GAAP operating margin, and non-GAAP net income. Non-GAAP financial measures exclude, but are not limited to, the amortization of intangible assets and the purchase accounting step-up adjustment on inventory and certain long term biological assets, and other charges and adjustments related to our acquisitions and divestitures, including incremental dividends attributable to Noveprim noncontrolling interest holders and the gain on our sale of our Avian Vaccine business; expenses associated with evaluating and integrating acquisitions and divestitures, including advisory fees and certain other transaction-related costs, 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; severance and other costs associated with our restructuring initiatives; the write-off of deferred financing costs and fees related to debt financing; investment gains or losses associated with our venture capital and other strategic equity investments; certain legal costs in our Microbial Solutions business related to environmental litigation and in our Safety Assessment business related to U.S. government investigations into the NHP supply chain; tax effect of all of the aforementioned matters; and adjustments related to the recognition of deferred tax assets expected to be utilized as a result of changes to the our international financing structure and the revaluation of deferred tax liabilities as a result of foreign tax legislation. This press release also refers to our revenue on both a GAAP and non-GAAP basis: on a non-GAAP basis, we define “organic revenue growth,” which we define as reported revenue growth adjusted for foreign currency translation, acquisitions, and divestitures. We exclude these items from the non-GAAP financial measures because they are outside our normal operations. There are limitations in using non-GAAP financial measures, as they are not presented 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 divestitures (and in certain cases, the evaluation of such acquisitions and divestitures, 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 and their underlying associated costs, such as business acquisitions, generally occur periodically but on an unpredictable basis. We calculate non-GAAP integration costs to include third-party integration costs incurred post-acquisition. Presenting revenue on an organic basis allows investors to measure our revenue growth exclusive of acquisitions, divestitures, and 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 presented 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.
