NEWS RELEASE


CHARLES RIVER LABORATORIES ANNOUNCES
SECOND-QUARTER 2025 RESULTS

– Second-Quarter Revenue of $1.03 Billion –

– Second-Quarter GAAP Earnings per Share of $1.06
and Non-GAAP Earnings per Share of $3.12 –
– Updates 2025 Guidance –

WILMINGTON, MA, August 6, 2025 – Charles River Laboratories International, Inc. (NYSE: CRL) today reported its results for the second quarter of 2025. For the quarter, revenue was $1,032.1 million, an increase of 0.6% from $1,026.1 million in the second quarter of 2024.
The impact of foreign currency translation increased reported revenue by 1.2%. Excluding this impact, revenue declined 0.5% on an organic basis. On a segment basis, an organic revenue decline in the Discovery and Safety Assessment (DSA) segment was partially offset by organic revenue growth in the Manufacturing Solutions (Manufacturing) and Research Models and Services (RMS) segments.
In the second quarter of 2025, the GAAP operating margin decreased to 9.7% from 14.8% in the second quarter of 2024. GAAP net income available to common shareholders for the second quarter of 2025 was $52.3 million, or $1.06 per share, a decrease from net earnings of $90.0 million, or $1.74 per diluted share, for the same period in 2024. The GAAP decreases were primarily driven by higher amortization expense related to accelerated amortization of certain CDMO client relationships, costs associated with the Company's restructuring activities, and certain third-party legal and advisory costs.
On a non-GAAP basis, the second-quarter operating margin increased to 22.1% from 21.3% in the second quarter of 2024. Non-GAAP net income was $154.0 million for the second quarter of 2025, an increase of 6.2% from $144.9 million for the same period in 2024. Second-quarter diluted earnings per share on a non-GAAP basis were $3.12, an increase of 11.4% from $2.80 per share for the second quarter of 2024. The non-GAAP increases were primarily driven by operating margin improvements in all three segments, partially offset by higher unallocated corporate costs. In addition, lower diluted shares outstanding due to the Company's stock repurchase program also contributed to the increase in non-GAAP earnings per share.
James C. Foster, Chair, President and Chief Executive Officer, said, “We are continuing to see clear signs that the biopharmaceutical demand is stabilizing, and in this environment, we are
1



making gradual progress to return to organic revenue growth. This progress was demonstrated in our solid second-quarter financial performance, driven principally by favorable results in our DSA segment.”
"Our clients understand that what truly differentiates Charles River from the competition is the strength and value proposition of our broad, scientifically distinguished portfolio and leading, non-clinical market position. With many of our global biopharmaceutical clients having progressed through their restructuring efforts and small and mid-sized biotech companies showing consistent demand trends, we believe our leading, early-stage development portfolio is extremely well positioned to succeed as the demand environment improves. The sustained improvement in our businesses may not be linear, but we are pleased that the DSA business – and our overall, non-GAAP financial results – will perform substantially better than we had initially expected this year,” Mr. Foster concluded.
Second-Quarter Segment Results
Research Models and Services (RMS)
Revenue for the RMS segment was $213.3 million in the second quarter of 2025, an increase of 3.3% from $206.4 million in the second quarter of 2024. The impact of foreign currency translation increased revenue by 1.0%. Organic revenue increased by 2.3%, due primarily to higher revenue for large research model products and for research model services, including the Genetically Engineered Models and Services (GEMS) and Insourcing Solutions businesses.
In the second quarter of 2025, the RMS segment’s GAAP operating margin increased to 16.8% from 14.5% in the second quarter of 2024. On a non-GAAP basis, the operating margin increased to 25.3% from 23.1%. The GAAP and non-GAAP operating margin increases were primarily driven by the favorable revenue mix related to large research models and operating leverage from higher revenue for research models services, as well as the benefit of cost savings resulting from the Company's restructuring initiatives.
Discovery and Safety Assessment (DSA)
Revenue for the DSA segment was $618.0 million in the second quarter of 2025, a decrease of 1.5% from $627.4 million in the second quarter of 2024. The impact of foreign currency translation increased DSA revenue by 1.1% and the divestiture of a small DSA site reduced reported revenue by 0.2%. Organic revenue decreased by 2.4%, driven primarily by lower sales volume for both discovery and regulated safety assessment services.
In the second quarter of 2025, the DSA segment’s GAAP operating margin decreased to 19.9% from 22.1% in the second quarter of 2024. The GAAP operating margin decline was primarily driven by lower revenue, higher costs associated with the Company's restructuring initiatives, and higher third-party legal costs related to U.S. government investigations into the Company's NHP supply chain. On a non-GAAP basis, the operating margin increased to 27.4% from 27.1% in the second quarter of 2024. The non-GAAP operating margin increase was primarily driven by the benefit of cost savings resulting from the Company's restructuring initiatives, partially offset by lower revenue.
2



Manufacturing Solutions (Manufacturing)
Revenue for the Manufacturing segment was $200.8 million in the second quarter of 2025, an increase of 4.4% from $192.3 million in the second quarter of 2024. The impact of foreign currency translation increased Manufacturing revenue by 1.5%. Organic revenue increased 2.9%, primarily driven by higher revenue in the Microbial Solutions business, which was partially offset by lower revenue in the Biologics Testing business.
The Manufacturing segment’s GAAP operating margin decreased to 6.0% from 19.4% in the second quarter of 2024 as a result of higher amortization expense related to accelerated amortization of certain CDMO client relationships. On a non-GAAP basis, the operating margin increased to 32.8% from 26.6% in the second quarter of 2024, driven primarily by revenue and payments associated with commercial CDMO clients, as well as operating leverage from higher revenue in the Microbial Solutions business.
Update on U.S. Department of Justice Investigation into Non-Human Primate Supply Chain
In July 2025, the U.S. Department of Interior informed the Company that the U.S. Fish and Wildlife Service had cleared non-human primate (NHP) shipments from late 2022 and early 2023 for legal entry into the United States. Furthermore, in recent weeks, the Company has been advised by the U.S. Department of Justice that the grand jury investigation and the parallel civil investigation relating to these NHP shipments had been closed.
Updates 2025 Guidance
The Company is updating its 2025 financial guidance, which was previously updated on May 7, 2025. The Company is increasing its full-year outlook for revenue and non-GAAP earnings per share to primarily reflect better-than-expected second-quarter financial results, particularly in the DSA segment, and to a lesser extent, a more favorable impact from foreign exchange.
The Company’s 2025 guidance for revenue 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, inclusive of the acceleration of amortization expense related to certain CDMO client relationships, as well as the purchase accounting step-up on inventory and certain long-term biological assets. In addition, these adjustments include some costs related to the evaluation and integration of acquisitions and divestitures.
(3) These adjustments primarily include site consolidation (including site transition costs), severance, impairment, and other costs related to the Company’s restructuring actions.
(4) 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.
(5) 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 DSA segment and (ii) certain third-party advisory costs related to the Company entering into a Cooperation Agreement with a shareholder.

Webcast
Charles River has scheduled a live webcast on Wednesday, August 6th, at 9:00 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 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
4



term biological assets, and other charges and adjustments related to our acquisitions and divestitures, including incremental dividends attributable to Noveprim noncontrolling interest holders; 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 certain other strategic equity investments; certain legal costs in our Microbial Solutions business related to environmental litigation and in our DSA segment related to U.S. government investigations into the NHP supply chain 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 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” 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.
