Charles River Laboratories International, Inc. (NYSE: CRL) today reported its results for the first quarter of 2026. For the quarter, revenue was $995.8 million, an increase of 1.2% from $984.2 million in the first quarter of 2025.

The impact of foreign currency translation increased reported revenue by 2.8%, while a divestiture reduced reported revenue by 0.1%. Excluding the effect of these items, revenue declined 1.5% on an organic basis. By segment, organic revenue growth in the Manufacturing Solutions (Manufacturing) segment was more than offset by organic revenue declines in the Research Models and Services (RMS) and Discovery and Safety Assessment (DSA) segments.

In the first quarter of 2026, the GAAP operating margin was 12.0%, compared to 7.6% in the first quarter of 2025. The increase in the GAAP operating margin was primarily driven by lower accelerated amortization expense related to certain CDMO client relationships. The GAAP net loss available to common shareholders for the first quarter of 2026 was $(14.8) million, or $(0.30) per diluted share, compared to GAAP net income of $25.5 million, or $0.50 per diluted share for the same period in 2025. The decrease was principally due to a loss on assets held for sale related to the CDMO and Cell Solutions divestiture totaling $118.0 million, or $1.53 per share.

On a non-GAAP basis, the first-quarter operating margin decreased to 16.3% from 19.1% in the first quarter of 2025, primarily as a result of higher study-related direct costs in the DSA segment, unfavorable revenue mix in the RMS segment, and higher stock-based compensation expense related largely to executive transition. Non-GAAP net income was $101.7 million for the first quarter of 2026, a decrease of 14.6% from $119.1 million for the same period in 2025. First-quarter diluted earnings per share on a non-GAAP basis were $2.06, a decrease of 12.0% from $2.34 per share in the first quarter of 2025. The non-GAAP net income and earnings per share decreases were driven primarily by the lower operating margin.

Birgit Girshick, Chief Executive Officer, said, "We are pleased to deliver on our first-quarter financial targets, and remain well positioned to generate improving results over the course of the year. Our confidence is supported by a DSA demand environment that is tracking to our expectations, resulting in solid bookings in the first quarter, as well as the successful execution of our strategy."

"As we look to the future, our focus remains on enhancing our clients' experience, strengthening our world-class scientific portfolio, achieving our financial and operational goals, and increasing long‑term shareholder value. We have already established a solid foundation and with a refreshed strategic focus aimed at modernizing the Company and the industry, we intend to continue to evolve and lead the way. By doing so, we will enable the Company to realize its full potential and ensure future success. I am energized to lead this great company into its next chapter of growth and am confident in the path we are taking to create the future for Charles River," Ms. Girshick concluded.

First-Quarter Segment Results

Research Models and Services (RMS)

Revenue for the RMS segment was $208.4 million in the first quarter of 2026, a decrease of 2.2% from $213.1 million in the first quarter of 2025. The impact of foreign currency translation increased revenue by 3.3%. Organic revenue decreased by 5.5%, due primarily to lower revenue for small research models in North America, as well as for large research models. The decline was partially offset by higher revenue for small research models in China.

In the first quarter of 2026, the RMS segment's GAAP operating margin increased to 23.9% from 20.5% in the first quarter of 2025, primarily due to a gain on the sale of real estate in Massachusetts. On a non-GAAP basis, the operating margin decreased to 24.7% from 27.1%. The non-GAAP operating margin decrease was primarily driven by the unfavorable revenue mix, principally related to small research models in North America and large research models.

Discovery and Safety Assessment (DSA)

Revenue for the DSA segment was $596.9 million in the first quarter of 2026, an increase of 0.7% from $592.6 million in the first quarter of 2025. The impact of foreign currency translation increased DSA revenue by 2.2%, while a divestiture reduced reported revenue by 0.1%. Organic revenue decreased by 1.4%, driven primarily by lower revenue for discovery services due in part to the impact of prior site consolidation activities.

In the first quarter of 2026, the DSA segment's GAAP operating margin increased to 17.4% from 15.9% in the first quarter of 2025. The increase was primarily driven by lower third-party legal costs related to a non-human primate (NHP) supply matter, as well as lower costs associated with the Company's restructuring and efficiency initiatives. On a non-GAAP basis, the operating margin decreased to 21.0% from 23.9% in the first quarter of 2025. The non-GAAP operating margin decrease was primarily driven by higher study-related direct costs associated with large-model sourcing and study starts.

Manufacturing Solutions (Manufacturing)

Revenue for the Manufacturing segment was $190.5 million in the first quarter of 2026, an increase of 6.8% from $178.5 million in the first quarter of 2025. The impact of foreign currency translation increased Manufacturing revenue by 3.9%. Organic revenue increased 2.9%, driven by higher revenue in the Microbial Solutions business, partially offset by lower revenue in the CDMO business.

The Manufacturing segment's GAAP operating margin was 24.6%, compared to (4.8)% in the first quarter of 2025. The increase was primarily the result of lower accelerated amortization expense related to certain CDMO client relationships. On a non-GAAP basis, the operating margin increased to 25.9% from 23.1% in the first quarter of 2025, driven primarily by the benefit of cost savings resulting from the Company's restructuring initiatives.

Divestiture Update

On May 6, 2026, the Company completed the previously announced divestiture of the CDMO and Cell Solutions businesses to GI Partners. In addition, the Company expects to complete the sale of certain European Discovery Services sites in May 2026. These strategic transactions will enable Charles River to refine and refocus its comprehensive portfolio on core competencies and drive synergistic growth in areas in which it has differentiated scientific expertise, including regulated drug development testing.

Stock Repurchase Update

During the first quarter of 2026, the Company repurchased 1.1 million shares for a total of $200.0 million. As of March 28, 2026, the Company had $800.0 million remaining under its $1.0 billion stock repurchase authorization that was approved by the Board of Directors on October 29, 2025.

2026 Guidance Update

The Company is reaffirming its 2026 organic revenue and non-GAAP earnings per share guidance, which was last updated on February 25, 2026, and previously included the expected impact of the completed divestiture of the CDMO and Cell Solutions businesses, as well as the planned divestiture of certain European Discovery Services sites in May 2026.

However, the Company is reducing its 2026 reported revenue outlook by approximately 50 basis points to reflect recent changes in assumptions for foreign exchange rates. The Company's GAAP earnings per share guidance has now been updated to primarily reflect the impact of the divestitures.

The Company's 2026 guidance for revenue and earnings per share is as follows:

Footnotes to Guidance Table:

(1) Revenue and earnings per share guidance assumes the planned divestiture of certain European Discovery Services sites will be completed in May 2026, and that the CDMO and Cell Solutions divestiture was completed on May 6, 2026.

(2) Organic revenue growth is defined as reported revenue growth adjusted for completed acquisitions and both completed and previously announced divestitures (including the CDMO and Cell Solutions businesses, as well as certain European Discovery Services sites), as well as foreign currency translation.

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

(4) These adjustments include costs related to the evaluation and integration of acquisitions and divestitures, as well as a loss on assets held for sale related to divestitures and other transaction-related tax adjustments.

(5) These adjustments primarily include site consolidation (including site transition costs), severance, impairment, third-party consulting and professional services, and other costs related to the Company's restructuring actions and efficiency initiatives. These adjustments also include gains and/or losses on the sale of certain assets and real estate.

(6) These adjustments primarily include immaterial items related to: (i) certain venture capital and other strategic investment losses/(gains), net. This item only includes recognized gains or losses on certain investments. The Company does not forecast the future performance of these investments; and (ii) reductions to a previous $27 million inventory charge associated with an NHP supply matter. As a result of the resolution of the U.S. government investigations during fiscal year 2025, certain NHPs were subsequently utilized.

Webcast

Charles River has scheduled a live webcast on Thursday, May 7 th , at 8:30 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.

Non-GAAP Reconciliations

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.

Use of Non-GAAP Financial Measures

This press release contains non-GAAP financial measures, such as non-GAAP earnings per 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 expenses associated with evaluating and integrating acquisitions and divestitures, including advisory fees, certain transition costs, 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, including the divestitures of our CDMO and Cell Solutions businesses, the sale of certain of our European Discovery Services sites, and the sale of certain assets including real estate; severance and other costs associated with our restructuring initiatives; investment gains or losses associated with our venture capital and certain other strategic equity investments; certain legal costs and adjustments related to an NHP inventory charge in our DSA segment related to now concluded U.S. government investigations into the NHP supply chain; legal and advisory costs related to entering into a Cooperation Agreement with a shareholder; tax effect of all of the aforementioned matters; and adjustments related to the derecognition of certain deferred tax assets due to the CDMO Gene Therapy intangible asset impairment charge, the recognition of deferred tax assets expected to be utilized as a result of changes to the Company's 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" 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.

Charles River management believes that supplementary non-GAAP financial measures provide useful information to allow investors to gain a meaningful understanding of our core operating results and future prospects, without the effect of often-one-time charges and other items which are outside our normal operations, consistent with the manner in which management measures and forecasts the Company's performance. The supplementary non-GAAP financial measures included are not meant to be considered superior to, or a substitute for results of operations prepared in accordance with U.S. GAAP. The Company intends to continue to assess the potential value of reporting non-GAAP results consistent with applicable rules, regulations and guidance.
