Charles River Laboratories Announces Second-Quarter 2026 Results

Key Terms

non-GAAP financial measures financial

Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

organic revenue growth financial

Organic revenue growth is the increase in a company's sales that comes from its existing products and services, without including any gains from acquisitions or selling off parts of the business. It reflects the company’s ability to attract more customers or encourage existing customers to buy more over time. For investors, it indicates the company's underlying strength and efficiency in expanding its core operations.

Next Generation Sequencing (NGS) technical

A laboratory method that reads large amounts of DNA or RNA quickly and affordably, like using a high-speed scanner to read thousands of books at once instead of one page at a time. Investors care because it powers modern diagnostics, drug discovery and personalized treatments, driving demand for testing services, instruments and related software; improvements or cost cuts can expand markets, change reimbursement and affect company growth prospects.

Second-Quarter Results

Revenue was $1.00 billion, a decrease of 2.7% from $1.03 billion in the second quarter of 2025. On an organic basis, revenue increased 0.1%, driven by revenue growth in the Manufacturing Solutions (Manufacturing) and Discovery and Safety Assessment (DSA) segments, offset by a decline in the Research Models and Services (RMS) segment. Organic revenue growth excludes the effect of acquisitions, divestitures, and foreign currency translation.

In the second quarter of 2026, the GAAP operating margin was 11.9%, compared to 9.7% in the second quarter of 2025. The increase in the GAAP operating margin was primarily driven by the CDMO business, including lower accelerated amortization expense related to certain client relationships. The GAAP net loss available to common shareholders for the second quarter of 2026 was $(1.5) million, or $(0.03) per diluted share, compared to GAAP net income of $52.3 million, or $1.06 per diluted share for the same period in 2025. The decrease was principally due to a loss related to the CDMO and Cell Solutions divestiture totaling $63.7 million, or $1.40 per share.

On a non-GAAP basis, the second-quarter operating margin decreased to 20.5% from 22.1% in the second quarter of 2025, primarily as a result of higher study-related direct costs in the DSA segment and higher unallocated corporate costs. Non-GAAP net income was $146.2 million for the second quarter of 2026, a decrease of 5.0% from $154.0 million for the same period in 2025. Second-quarter diluted earnings per share on a non-GAAP basis were $3.02, a decrease of 3.2% from $3.12 per share in the second quarter of 2025. The non-GAAP net income and earnings per share decreases were driven primarily by the lower operating margin. The earnings per share decrease was partially offset by investment gains associated with the Company's deferred compensation plan, which totaled a net benefit of $0.19 per share in the second quarter.

Birgit Girshick, Chief Executive Officer, said, "We made excellent progress in the second quarter on the execution of our Pathway to Purpose strategy. We are actively evaluating opportunities to modernize the Company and drive greater efficiency, to strengthen our leading drug development portfolio centered on regulated testing, and to further enhance our growth profile. We are focused on continuing to move forward on achieving our strategic initiatives and financial goals, which will strengthen our foundation and underpin our future success."

"We were encouraged that the demand environment continued to strengthen in the second quarter, particularly for our DSA segment, as evidenced by the fact that we recorded the highest net book-to-bill in nearly four years. This improvement was broad based across our global biopharmaceutical and small and mid-sized biotechnology clients, and it is our goal to continue to capture additional share of our clients’ R&D spending by providing client-centric solutions and by leveraging our global scale and deep scientific expertise. As a result of our collective efforts, we delivered on our second-quarter financial targets – exceeding our prior outlook – and are raising our revenue and non-GAAP earnings per share guidance for the year," Ms. Girshick concluded.

Second-Quarter Segment Results

Research Models and Services (RMS)

Revenue for the RMS segment was $209.5 million in the second quarter of 2026, a decrease of 1.8% from $213.3 million in the second quarter of 2025. Organic revenue decreased by 1.4%, due primarily to lower revenue for small research models in North America, as well as for research model services. The decline was partially offset by higher revenue for small research models in China.

In the second quarter of 2026, the RMS segment’s GAAP operating margin increased to 17.3% from 16.8% in the second quarter of 2025, primarily due to lower amortization of intangible assets related to the sale of the Cell Solutions business. On a non-GAAP basis, the operating margin decreased to 24.5% from 25.3%. The non-GAAP operating margin decrease was primarily driven by the impact of lower sales volume and an unfavorable geographic revenue mix.

Discovery and Safety Assessment (DSA)

Revenue for the DSA segment was $606.5 million in the second quarter of 2026, a decrease of 1.9% from $618.0 million in the second quarter of 2025. Organic revenue increased by 0.2%, driven primarily by higher study volume for regulated safety assessment services.

In the second quarter of 2026, the DSA segment’s GAAP operating margin increased to 20.5% from 19.9% in the second quarter of 2025. The increase was primarily driven by lower amortization of intangible assets related to the divestiture of certain European Discovery Services sites and lower third-party legal costs related to a non-human primate (NHP) supply matter. On a non-GAAP basis, the operating margin decreased to 25.6% from 27.4% in the second quarter of 2025. The non-GAAP operating margin decrease was primarily driven by higher study-related direct costs.

Manufacturing Solutions (Manufacturing)

Revenue for the Manufacturing segment was $188.1 million in the second quarter of 2026, a decrease of 6.3% from $200.8 million in the second quarter of 2025, primarily driven by the CDMO divestiture. Organic revenue increased 1.3%, driven primarily by higher revenue in the Microbial Solutions business.

The Manufacturing segment’s GAAP operating margin was 34.9%, compared to 6.0% in the second quarter of 2025. On a non-GAAP basis, the operating margin increased to 37.8% from 32.8% in the second quarter of 2025. The GAAP and non-GAAP increases were driven primarily by the CDMO business, including the benefit from the divestiture.

Stock Repurchase Update

The Company repurchased 1.7 million shares for a total of $300.0 million during the year-to-date period ended June 27, 2026, including 0.6 million shares for a total of $100.0 million in the second quarter of 2026. As of June 27, 2026, the Company had $700.0 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 increasing its 2026 revenue and non-GAAP earnings per share guidance, which was last updated on May 7, 2026. This increase primarily reflects the expected operational outperformance for the year, including in the second quarter, due primarily to improving demand trends in the DSA segment and better-than-expected performance in the Manufacturing segment. For the year, the Company expects the second-quarter investment gains associated with the deferred compensation plan will be largely offset by a higher tax rate, resulting in a negligible net impact to non-GAAP earnings per share.

On a GAAP basis, the Company is reducing its earnings per share guidance due primarily to the net loss related to the divestitures.

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

2026 GUIDANCE	CURRENT	PRIOR
Revenue growth/(decrease), reported	(3.5)% - (2.5)%	(5.5)% - (4.0)%
Less: Contribution from acquisitions	0.0% - (0.5)%	0.0% - (0.5)%
Add: Impact from divestitures	~4.5%	~5.0%
Less: Favorable impact of foreign exchange	(0.5)% - (1.0)%	(0.5)% - (1.0)%
Revenue growth/(decrease), organic (1)	0.0% - 1.0%	(1.5)% - (0.5)%
GAAP EPS estimate	$3.05 – $3.35	$5.35 – $5.85
Acquisition-related amortization (2)	~$2.30	~$2.30
Acquisition- and divestiture-related costs (3)	~$4.75	~$2.30
Costs associated with restructuring and efficiency initiatives (4)	~$1.20	~$0.85
Other, net (5)	($0.17)	NM
Non-GAAP EPS estimate	$11.15 – $11.45	$10.80 – $11.30

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.

(1)		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.
(2)		Amortization related to acquisitions for the three and six months ended June 28, 2025 includes $35.5 million and $71.0 million of accelerated amortization of certain client relationships in the Biologics Solutions reporting unit within the Manufacturing Solutions reportable segment.
(3)		These adjustments are related to the evaluation and integration of acquisitions and divestitures, and primarily include transaction, advisory, certain third-party integration, certain compensation costs, and related costs; as well as fair value adjustments associated with contingent consideration arrangements.
(4)		Cost savings and efficiency initiatives in 2026 primarily include site consolidation charges related to recent site optimization activities, cost of professional services related to certain improvement initiatives, and a pre-tax gain of $38.5 million in connection with the sale of certain assets in Wilmington, Massachusetts. The gain was recognized within RMS reportable segment and unallocated corporate for $23.2 million and $15.3 million, respectively.
(5)		Within the DSA business, third‑party legal and advisory costs incurred during fiscal 2025 relate to U.S. government investigations into the NHP supply chain, which were concluded in fiscal 2025. Also included within DSA results for fiscal 2026 is the utilization of previously written‑down NHP inventory, resulting in partial reversals of the $27 million inventory charge recorded in fiscal 2024 following the resolution of the matter in fiscal 2025. Within Unallocated Corporate, third-party legal and advisory costs incurred during fiscal 2025 are associated with the execution of the Cooperation Agreement with a shareholder.
