Special Note on Factors Affecting Future Results
This Quarterly Report on Form 10-Q contains forward-looking statements regarding future events and the future results of Charles River Laboratories International, Inc. that are based on our current expectations, estimates, forecasts and projections about the industries in which we operate and the beliefs and assumptions of our management. Words such as “expect,” “anticipate,” “target,” “goal,” “project,” “intend,” “plan,” “believe,” “seek,” “estimate,” “will,” “likely,” “may,” “designed,” “would,” “future,” “can,” “could,” and other similar expressions which are predictions of, indicate future events and trends or which do not relate to historical matters, are intended to identify such forward-looking statements. These statements are based on our current expectations and beliefs and involve a number of risks, uncertainties and assumptions that are difficult to predict.
For example, we may use forward-looking statements when addressing topics such as: our expectations regarding the availability of non-human primates and our ability to diversify our non-human primate (NHP) supply chain; the outcome of (1) the U.S. government investigations and inquiries related to the NHP supply chain (including shipments of non-human primates from Cambodia received by the Company), (2) the putative securities class action lawsuit filed against us and certain current/former officers on May 19, 2023, (3) the derivative lawsuit filed against members of the Board of Directors and certain current/former officers on November 8, 2023, and (4) the derivative lawsuit filed against certain current/former members of the Board of Directors and certain current/former officers on August 2, 2024; the timing and impact of the development and implementation of enhanced procedures to reasonably ensure that non-human primates we source are purpose-bred; changes and uncertainties in the global economy and financial markets, including any changes in business, political, or economic conditions due to the November 16, 2022 announcement by the U.S. Department of Justice through the U.S. Attorney’s Office for the Southern District of Florida that a Cambodian non-human primate supplier and two Cambodian officials had been criminally charged in connection with illegally importing non-human primates into the United States; client demand, particularly future demand for drug discovery and development products and services, including the outsourcing of these services; our expectations with respect to our ability to meet financial targets; our expectations regarding stock repurchases, including the number of shares to be repurchased, expected timing and duration, the amount of capital that may be expended and the treatment of repurchased shares; our ability to successfully execute our business strategy; our ability to timely build infrastructure to satisfy capacity needs and support business growth, our ability to fund our operations for the foreseeable future, the impact of unauthorized access into our information systems, including the timing and effectiveness of any enhanced security and monitoring present spending trends and other cost reduction activities by our clients; future actions by our management; the outcome of contingencies; changes in our business strategy, business practices and methods of generating revenue; the development and performance of our services and products; market and industry conditions, including competitive and pricing trends and the impact of those conditions, including on our allowances for credit losses; our strategic relationships with leading pharmaceutical and biotechnology companies, venture capital investments, and opportunities for future similar arrangements; our cost structure; our expectations regarding our acquisitions and divestitures, including their impact and projected timing; our expectations with respect to revenue growth and operating synergies (including the impact of specific actions intended to cause related improvements); the nature, timing and impact of specific actions intended to improve overall operating efficiencies and profitability (and our ability to accommodate future demand with our infrastructure), including actions to optimize our global footprint, and gains and losses attributable to businesses we plan to close, consolidate, divest or repurpose and the impact of operations and restructuring actions (including as estimated on an annualized basis); our expectations with respect to our study cancellation rates and the impact of such cancellations; our expectations with respect to tax rates and benefits; changes in our expectations regarding future stock option, restricted stock, performance share units and other equity grants to employees and directors; expectations with respect to foreign currency exchange; assessing (or changing our assessment of) our tax positions for financial statement purposes; our liquidity; and the impact of litigation, including our ability to successfully defend litigation against us. In addition, these statements include the impact of economic and market conditions on us and our clients, the effects of our cost-saving actions and the steps to optimize returns to shareholders on an effective and timely basis; and our ability to withstand the current market conditions.
Forward-looking statements are predictions and are subject to risks, uncertainties and assumptions that are difficult to predict. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document, or in the case of statements incorporated by reference, on the date of the document incorporated by reference. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in our Annual Report on Form 10-K for the year ended December 30, 2023, under the sections entitled “Our Strategy,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and in this Quarterly Report on Form 10-Q, under the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors,” in our press releases, and other financial filings with the Securities and Exchange Commission. We have no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or risks. New information, future events, or risks may cause the forward-looking events we discuss in this report not to occur.

Certain reclassifications of prior year amounts have been made to conform to the current year presentation. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all normal and recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations.
Use of Estimates
The preparation of unaudited condensed consolidated financial statements in accordance with U.S. GAAP requires that the Company make estimates and judgments that may affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, judgments, and methodologies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known.
Newly Issued Accounting Pronouncements
In November 2023, the FASB issued ASU 2023-07, “Improvements to Reportable Segment Disclosures (Topic 280)”. ASU 2023-07 modifies reportable segment disclosure requirements, primarily through enhanced disclosures about segment expenses categorized as significant or regularly provided to the Chief Operating Decision Maker (CODM). In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and the amendments in this update are required to be applied on a retrospective basis. The Company is currently evaluating the impact this new standard will have on the related disclosures on the consolidated financial statements, but does not believe there will be a material impact.
In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures (Topic 740)”. ASU 2023-09 requires enhanced disclosures on income taxes paid, adds disaggregation of continuing operations before income taxes between foreign and domestic earnings and defines specific categories for the reconciliation of jurisdictional tax rate to effective tax rate. This ASU is effective for fiscal years beginning after December 15, 2024, and can be applied on a prospective basis. The Company is currently evaluating the impact this new standard will have on the related disclosures on the consolidated financial statements.
Summary of Significant Accounting Policies
The Company’s significant accounting policies are described in Note 1, “Description of Business and Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for fiscal year 2023 as filed with the SEC on February 14, 2024.
Consolidation
The Company’s unaudited condensed consolidated financial statements reflect its financial statements and those of its subsidiaries in which the Company holds a controlling financial interest. For consolidated entities in which the Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its unaudited condensed consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. Redeemable noncontrolling interests, where the noncontrolling interest holders have the ability to require the Company to purchase the remaining interests, are classified in the mezzanine section of the unaudited condensed consolidated balance sheets, which is presented above the equity section and below liabilities. Intercompany balances and transactions are eliminated in consolidation.
The Company’s fiscal year is typically based on 52-weeks, with each quarter composed of 13 weeks ending on the last Saturday on, or closest to, March 31, June 30, September 30, and December 31. A 53rd week in the fourth quarter of the fiscal year is occasionally necessary to align with a December 31 calendar year-end.

2. ACQUISITIONS AND DIVESTITURES
Fiscal 2023 Acquisition
Noveprim Group
On November 30, 2023, the Company completed the acquisition of an additional 41% equity interest of Noveprim Group (Noveprim), a leading supplier of non-human primates (NHPs) located in Mauritius, resulting in a 90% controlling interest. The Company had previously acquired a 49% equity interest in 2022 for $90.0 million plus additional contingent payments up to $5.0 million based on future performance. The total consideration allocable to the Noveprim acquisition is $392.4 million, which includes $144.6 million additional cash paid for the 41% equity interest, elimination of historical activity and intercompany balances of $209.5 million which includes a remeasurement gain on the 49% equity investment of $113.0 million, contingent consideration of $33.3 million, deferred purchase price of $12.0 million payable from 2024 through 2027, offset by estimated post-closing adjustments for working capital of $7.0 million. The purchase price reflected an agreement with seller on working capital and debt, which was adjusted from $13.8 million to $7.0 million during the nine months ended September 28, 2024. As a result of measurement period adjustments to the purchase price, goodwill and remeasurement gains on the previous 49% equity investment for the nine months ended September 28, 2024, were increased by $17.6 million and $9.8 million, respectively. Remeasurement gains are recorded in Other income (expense), net, within the unaudited condensed consolidated statements of income. The contingent consideration fair value is estimated using a Monte Carlo Simulation model and the maximum contingent contractual payments are up to $55.0 million based on future performance and milestone achievements in fiscal years 2023 through 2025. The Company has the call option right to purchase the remaining 10% equity interest up until one month after the sixth anniversary of closing the 41% equity interest. On the first anniversary of the expiration of the call option, a 12-month put option will be triggered giving the seller the right to require the Company to acquire the remaining shares of the seller. The redemption price for the call/put is fixed and ranges from $47.0 million to $54.0 million depending on when exercised. The noncontrolling interest is classified as a redeemable noncontrolling interest in the mezzanine section of the unaudited condensed consolidated balance sheets. The acquisition was funded through a combination of available cash and proceeds from the Company’s Credit Facility. This business is reported as part of the Company’s DSA reportable segment for NHPs vertically integrated into the DSA supply chain and the RMS reportable segment for those NHPs sold to third party customers. The Company incurred transaction and integration costs in connection with the acquisition of $0.3 million and $0.7 million for the three months ended September 28, 2024 and September 30, 2023, respectively, which was primarily included in Selling, general and administrative expenses within the unaudited condensed consolidated statements of income. The Company incurred transaction and integration costs in connection with the acquisition of $1.2 million and $2.9 million for the nine months ended September 28, 2024 and September 30, 2023, respectively, which was primarily included in Selling, general and administrative expenses within the unaudited condensed consolidated statements of income.

The Company estimates the fair value of contingent consideration obligations through valuation models, such as probability-weighted and option pricing models, which incorporate probability adjusted assumptions and simulations related to the achievement of the milestones and the likelihood of making related payments. The unobservable inputs used in the fair value measurements include the probabilities of successful achievement of certain financial targets, forecasted results or targets, volatility, and discount rates. The remaining maximum potential payments are approximately $55.0 million, of which the value accrued as of September 28, 2024 is $39.9 million as the probability of achieving the maximum target is estimated to be 73%. The volatility and weighted average cost of capital is approximately 5% and 8%, respectively. Increases or decreases in these assumptions may result in a higher or lower fair value measurement, respectively.

Cash Flow Hedge
The Company is exposed to market fluctuations in interest rates as well as variability in foreign exchange rates. The Company had an interest rate swap with a notional amount of $500 million maturing November 2, 2024 to manage interest rate fluctuation related to floating rate borrowings under the Credit Facility, at a fixed rate of 4.65%.
Debt Instruments
The book value of the Company’s revolving loans, which are variable rate loans carried at amortized cost, approximates the fair value based on current market pricing of similar debt. As the fair value is based on significant other observable inputs, including current interest and foreign currency exchange rates, it is deemed to be Level 2 within the fair value hierarchy.
The book value of the Company’s Senior Notes are fixed rate obligations carried at amortized cost. Fair value is based on quoted market prices as well as borrowing rates available to the Company. As the fair value is based on significant other observable outputs, it is deemed to be Level 2 within the fair value hierarchy.

(1) DSA includes accumulated impairment losses of $1 billion, which were recognized in fiscal years 2008 and 2010.
The increase in goodwill during the nine months ended September 28, 2024 is related to measurement period adjustments related to the acquisition of Noveprim in the DSA reportable segment and foreign exchange in Manufacturing.
During the third quarter ended September 28, 2024, a triggering event was identified for the Discovery Services reporting unit (part of the DSA reportable segment). This resulted from a continuous decline in market conditions and operational challenges, ultimately resulting in a reduction of Discovery Services’ long range financial outlook. In response, management conducted a quantitative impairment test for goodwill to determine if the goodwill in the Discovery Services reporting unit was impaired. Upon completion of a quantitative impairment test, it was determined that the fair value of the reporting unit exceeded its carrying value by approximately 22%, and no impairment was recognized as of September 28, 2024. While the Discovery Services reporting unit is not currently impaired, the Company will continue to closely monitor future performance and any potential impacts on the value of the reporting unit.

Treasury Shares
On August 2, 2024, the Company’s Board of Directors approved a stock repurchase authorization of $1.0 billion. This authorization fully replaces a prior stock repurchase authorization of $1.3 billion that had $129.1 million remaining when it was terminated. During the three and nine months ended September 28, 2024, the Company repurchased 0.5 million shares of common stock for $100.7 million under the new stock repurchase program. As of September 28, 2024, the Company had $899.3 million remaining on the current authorized stock repurchase program.
The Company’s stock-based compensation plans permit the netting of common stock upon vesting of RSUs and PSUs in order to satisfy individual statutory tax withholding requirements. The Company acquired shares of approximately 0.1 million in the nine months ended September 28, 2024 and nine months ended September 30, 2023, for $18.4 million and $24.0 million, respectively, from such netting.

Redeemable Noncontrolling Interests
Through September 28, 2024, the Company holds several redeemable noncontrolling interests. Since the Company has the right to purchase, and the noncontrolling interest holders have the right to require the Company to purchase the remaining interest, which represents a derivative embedded within the equity instrument, the noncontrolling interest is classified in the mezzanine section of the unaudited condensed consolidated balance sheets, which is presented above the equity section and below liabilities.
The redeemable noncontrolling interests are measured at the greater of (i) the redemption amount or (ii) the historical value resulting from the original acquisition date fair value, increased or decreased for the noncontrolling interest’s share of net income (loss), equity capital contributions and distributions. The fair value of the redeemable noncontrolling interest is determined using the income approach, with key assumptions being projected cash flows and discount rates based on market participant’s weighted average cost of capital. To the extent redemption value exceeds carrying value, adjustments are recorded to additional paid-in capital, with any cumulative excess of redemption value over fair value recorded in retained earnings, which impacts net income available to common shareholders used in the calculation of earnings per common share.
Noveprim
The Company holds a 90% ownership interest in Noveprim. The Company has the right to purchase, and the noncontrolling interest holders have the right to sell, the remaining 10% equity interest at a fixed redemption value that ranges from $47.0 million to $54.0 million depending on when exercised. The Company has the call option right to purchase the remaining 10% equity up until one month after the sixth anniversary of closing the 41% equity stake (December 2029). On the first anniversary of the expiration of the call option (December 2030), a 12-month put option will be triggered giving the seller the right to require the Company to acquire the remaining shares of the seller for $54.0 million. Additionally, during fiscal year 2024 the 10% noncontrolling interest holders have and may continue to receive a dividend disproportionate to their equity ownership, of which the fair value of $8.0 million as of the acquisition date was recorded within the redeemable noncontrolling interest. Through September 28, 2024, incremental dividends based on Noveprim statutory net income attributed to the redeemable noncontrolling interest holders of $9.6 million reduced net income available to common shareholders used in the calculation of earnings per common share. The redemption value is accreted to the put purchase price of $54.0 million using the interest method through December 2030. As of September 28, 2024, the redemption value of $40.6 million exceeded both the carrying value and fair value, resulting in both an adjustment to additional paid in capital of $7.2 million and an adjustment to retained earnings of $1.1 million, respectively, for the nine months ended September 28, 2024.
Other redeemable noncontrolling interest
In 2019, the Company acquired an 80% equity interest in a subsidiary, which included a 20% redeemable noncontrolling interest. In June 2022, the Company purchased an additional 10% interest in the subsidiary for $15.0 million, resulting in a remaining noncontrolling interest of 10%. Beginning in 2024, the Company had the right to purchase, and the noncontrolling interest holders had the right to sell, the remaining 10% equity interest at its appraised value. The redemption value was measured at the greater of the appraised value or a predetermined floor. The amount that the Company could be required to pay to purchase the remaining 10% equity interest was not limited. As of March 30, 2024, the redemption value of $12.0 million exceeded the carrying value, resulting in an adjustment to additional paid in capital of $2.8 million. During the second quarter of fiscal 2024, the Company acquired the remaining 10% for $12.0 million.

Vital River
The Company held a 92% ownership interest in Vital River, a commercial provider of research models and related services in China as of December 31, 2022. The Company had the right to purchase, and the noncontrolling interest holders had the right to sell, the remaining 8% equity interest at a contractually defined redemption value, subject to a redemption floor. The amount that the Company could be required to pay to purchase the remaining 8% equity interest was not limited. During 2023, the Company acquired the remaining 8% and paid $4.8 million of the total $24.4 million due. The remaining purchase price payable was included in Accrued liabilities within the Company’s unaudited condensed consolidated balance sheet as of September 28, 2024 and December 30, 2023 and is expected to be paid during fiscal year 2024.
Nonredeemable Noncontrolling Interest
The Company has an investment in an entity whose financial results are consolidated in the Company’s unaudited condensed consolidated financial statements, as it has the ability to exercise control over this entity. The interest of the noncontrolling party in this entity has been recorded as nonredeemable noncontrolling interest within Equity in the accompanying unaudited condensed consolidated balance sheets. The activity within the nonredeemable noncontrolling interest was not material during the three and nine months ended September 28, 2024 and September 30, 2023.
13. INCOME TAXES
The Company’s effective tax rates for the three months ended September 28, 2024 and September 30, 2023 were 23.0% and 22.0%, respectively. The increase in the effective tax rate for the three months ended September 28, 2024 compared to the corresponding prior year period was primarily attributable to the deferred tax impact of tax law changes enacted during the three months ended September 28, 2024, offset by jurisdictional earnings mix.
The Company’s effective tax rates for the nine months ended September 28, 2024 and September 30, 2023 were 22.9% and 21.8%, respectively. The increase in the effective tax rate for the nine months ended September 28, 2024 compared to the same prior year period is primarily attributable the same reason as above, as well as decreased tax benefit from stock-based compensation deductions in nine months ended September 28, 2024.
For the three months ended September 28, 2024, the Company’s unrecognized tax benefits increased by $1.2 million to $25.2 million, primarily due to increases in research and development tax credit reserves, as well as unfavorable foreign exchange movement. For the three months ended September 28, 2024, the amount of unrecognized income tax benefits that would impact the effective tax rate increased by $1.0 million to $22.1 million for the same reasons discussed above. The accrued interest on unrecognized tax benefits was $1.8 million as of September 28, 2024. The Company estimates that it is reasonably possible that the unrecognized tax benefits will decrease by approximately $5.1 million over the next twelve-month period, primarily due to audit settlements and expiring statutes of limitations.

The Company conducts business in a number of tax jurisdictions. As a result, it is subject to tax audits on a regular basis including, but not limited to, such major jurisdictions as the U.S., the U.K., China, France, Germany, and Canada. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2020.
The Company and certain of its subsidiaries have ongoing tax controversies in the U.S., Canada, and India. The Company does not anticipate resolution of these audits will have a material impact on its unaudited condensed consolidated financial statements.
14. RESTRUCTURING AND ASSET IMPAIRMENTS
The Company has undertaken restructuring actions impacting the reportable segments at various locations across North America, Europe and Asia. This includes workforce right-sizing actions resulting in severance and transition costs; and costs related to the consolidation of facilities resulting in asset impairment, accelerated depreciation charges, and certain other costs. Generally, these actions are in response to recent macroeconomic impacts on the Company. During fiscal year 2023, the Company began to take restructuring actions as a result of these emerging business trends. The Company incurred restructuring charges of $30.6 million and $65.6 million during the three and nine months ended September 28, 2024, respectively and approximately $95 million since the beginning of fiscal year 2023 through September 28, 2024.

15. COMMITMENTS AND CONTINGENCIES
Litigation
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of the Company’s supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which guides the release of each import by USFWS. Notwithstanding the Company’s efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain shipments in the United States. The carrying value of the inventory related to these shipments was approximately $27 million as of September 28, 2024, which reflects the value of the shipments in accordance with the Company’s inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena and additional inquiries, primarily related to the sourcing of non-human primates and related disclosures, and the Company is cooperating with these requests. The Company is not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or resolved. The Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities.
A putative securities class action (Securities Class Action) was filed on May 19, 2023 against the Company and a number of its current/former officers in the United States District Court for the District of Massachusetts. On August 31, 2023, the court

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
appointed the State Teachers Retirement System of Ohio as lead plaintiff. An amended complaint was filed on November 14, 2023 that, among other things, included only James Foster, the Chief Executive Officer and David R. Smith, the former Chief Financial Officer as defendants along with the Company. The amended complaint asserts claims under §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act") on behalf of a putative class of purchasers of Company securities from May 5, 2020 through February 21, 2023, alleging that certain of the Company’s disclosures about its practices with respect to the importation of non-human primates made during the putative class period were materially false or misleading. On July 1, 2024, the court dismissed the complaint, denied the plaintiff’s informal request for leave to amend, and entered judgment for defendants. On July 30, 2024, the plaintiff filed a notice of appeal in the United States Court of Appeals for the First Circuit. While the Company cannot predict the final outcome of this matter, it believes the class action to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.
On November 8, 2023, a stockholder filed a derivative lawsuit in the U.S. District Court of the District of Delaware asserting claims on the Company’s behalf against the members of the Company’s Board of Directors and certain of the Company’s current/former officers (James Foster, the Chief Executive Officer; David R. Smith, the former Chief Financial Officer; and Flavia Pease, the current Chief Financial Officer). The complaint alleges that the defendants breached their fiduciary duties to the Company and its stockholders because certain of the Company’s disclosures about its practices with respect to the importation of non-human primates were materially false or misleading. The complaint also alleges that the defendants breached their fiduciary duties by causing the Company to fail to maintain adequate internal controls over securities disclosure and compliance with applicable law and by failing to comply with the company’s Code of Business Conduct and Ethics. The lawsuit is currently stayed by agreement of the parties pending further developments in the Securities Class Action pending in the United States Court of Appeals for the First Circuit. On August 2, 2024, a different stockholder filed a lawsuit in the U.S. District Court of Delaware asserting similar derivative claims on the Company’s behalf against members of the Company’s current and former Board of Directors and the same current/former officers based on similar allegations of purportedly misleading disclosures and non-compliance with legal rules and ethics standards in respect of the importation of non-human primates, as well as insider-trading claims against certain of the defendants. The lawsuit is currently stayed by agreement of the parties pending further developments in the Securities Class Action pending in the United States Court of Appeals for the First Circuit. While the Company cannot predict the outcome of these matters, it believes the derivative lawsuits to be without merit and plans to vigorously defend against them. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with these matters.
Aside from the matters above, the Company believes there are no other matters pending against the Company that could have a material impact on the Company’s business, financial condition, or results of operations.

U.S. Government Investigations into the Non-Human Primate Supply Chain
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the
27

civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain shipments in the United States. The carrying value of the inventory related to these shipments is approximately $27 million as of September 28, 2024, which reflects the value of the shipments in accordance with our inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena and additional inquiries, primarily related to the sourcing of non-human primates and related disclosures, and the Company is cooperating with these requests. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or resolved. The Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities. For our assessment of risk factors surrounding the aforementioned matter refer to Item 1A, “Risk Factors” and Item 3, “Legal Proceedings” of our Annual Report on Form 10-K for fiscal year 2023.
Recent Acquisitions
Our strategy is to augment internal growth of existing businesses with complementary acquisitions. Our recent acquisitions are described below.
Fiscal Year 2023 Acquisitions
On November 30, 2023, we completed our acquisition of an additional 41% equity interest of Noveprim Group (“Noveprim”), a leading provider of non-human primates (“NHPs”) used for biomedical, pharmaceutical and toxicological research purposes, resulting in a 90% controlling interest. The acquisition strengthens and diversifies the supply chain for our DSA segment. We had previously acquired a 49% equity stake in 2022 for $90.0 million up-front and additional contingent payments up to $5.0 million based on future performance. The total purchase price for the Noveprim acquisition is $392.4 million, which includes $144.6 million additional cash paid for the 41% equity interest, elimination of historical activity and intercompany balances of $209.5 million which includes a remeasurement gain on the 49% equity investment of $113.0 million, contingent consideration of $33.3 million, deferred purchase price of $12.0 million payable from 2024 through 2027, offset by estimated post-closing adjustments for working capital of $7.0 million. The purchase price reflected an agreement with seller on working capital and debt, which was adjusted from $13.8 million to $7.0 million during the nine months ended September 28, 2024. As a result of measurement period adjustments to the purchase price, goodwill and remeasurement gains on the previous 49% equity investment for the nine months ended September 28, 2024, were increased by $17.6 million and $9.8 million, respectively. The acquisition was funded through a combination of available cash and proceeds from our Credit Facility. This business is reported as part of our DSA reportable segment for NHPs vertically integrated into our Safety Assessment supply chain and the RMS reportable segment for NHPs sold to third party customers.
On January 27, 2023, we acquired SAMDI Tech, Inc., (SAMDI), a leading provider of high-quality, label-free high-throughput screening (HTS) solutions for drug discovery research. The acquisition of SAMDI provided clients with seamless access to the premier, label-free HTS MS platform and created a comprehensive library of drug discovery solutions. The purchase price of SAMDI was $62.8 million, inclusive of a 20% strategic equity interest previously owned by us. The acquisition was funded through a combination of available cash and proceeds from our Credit Facility. This business is reported as part of our DSA reportable segment.
Fiscal Quarters
Our fiscal year is typically based on 52-weeks, with each quarter composed of 13 weeks ending on the last Saturday on, or closest to, March 31, June 30, September 30, and December 31. A 53rd week in the fourth quarter of the fiscal year is occasionally necessary to align with a December 31 calendar year-end.
Global Market Environment
We are seeing a more cautious spending environment from our client base, principally global biopharmaceutical and biotechnology clients within our DSA segment, as they reassess their budgets, reprioritize their drug pipelines, and manage their cost structures. DSA backlog decreased to $2.1 billion as of September 28, 2024 from $2.5 billion as of December 30, 2023.
During the third quarter ended September 28, 2024, a triggering event was identified for the Discovery Services reporting unit (part of the DSA reportable segment). This resulted from a continuous decline in market conditions and operational challenges, ultimately resulting in a reduction of Discovery Services’ long range financial outlook. In response, management conducted a quantitative impairment test for goodwill to determine if the goodwill in the Discovery Services reporting unit was impaired. Upon completion of a quantitative impairment test, it was determined that the fair value of the reporting unit exceeded its
28
CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
carrying value by approximately 22%, with a goodwill carrying value of $334.8 million as of September 28, 2024. The reporting unit’s fair value could be adversely affected and result in an impairment of goodwill if actual cash flows are below estimated cash flows, the estimated cash flows are discounted at a higher risk-adjusted rate or market multiples decrease. While the Discovery Services reporting unit is not currently impaired, the Company will continue to closely monitor future performance and any potential impacts on the value of the reporting unit.
In response to recent trends observed across each of our businesses, we have undertaken and will continue to implement restructuring actions at various locations across North America, Europe and Asia. This includes workforce right-sizing actions, resulting in severance and transition costs; and costs related to the consolidation of facilities to optimize our global footprint and drive greater operating efficiency across the Company, resulting in asset impairment, accelerated depreciation, and other site consolidation charges.
During fiscal year 2023, we began taking restructuring actions as a result of these emerging business trends. We incurred restructuring charges of $30.6 million and $65.6 million during the three and nine months ended September 28, 2024, and approximately $95 million since the beginning of fiscal year 2023 through September 28, 2024. We expect that these effectuated actions, as well as other upcoming planned actions designed to optimize our global footprint to drive greater operating efficiency, will result in approximately $200 million of cost savings on an annualized basis, of which approximately $100 million will impact fiscal year 2024.
Results of Operations
Consolidated Results of Operations and Liquidity
Revenue for three months ended September 28, 2024 decreased $16.9 million, or 1.6%, to $1,009.8 million compared to $1,026.6 million in the corresponding period in 2023. Revenue for the nine months ended September 28, 2024 decreased $68.5 million, or 2.2%, to $3,047.4 million compared to $3,115.9 million in the corresponding period in 2023. The decreases in revenue were primarily due to our DSA business which experienced lower volume; partially offset by higher revenue within our Manufacturing businesses and the recent acquisition of Noveprim when compared to the corresponding periods in 2023.
In the three months ended September 28, 2024, our operating income and operating income as a percentage of revenue were $117.4 million and 11.6% respectively, compared with $151.5 million and 14.8% respectively, in the corresponding period of 2023. In the nine months ended September 28, 2024, our operating income and operating income as a percentage of revenue were $395.0 million and 13.0% respectively, compared with $484.3 million and 15.5%, respectively, in the corresponding period of 2023. The decrease in operating income and operating income as a percentage of revenue for the three and nine months ended September 28, 2024 were primarily due to the revenue impacts described above coupled with charges related to recent restructuring activities, including severance, asset impairments, and other site consolidation costs as discussed in Global Market Environment above.
Net income available to Charles River Laboratories International Inc, common shareholders decreased to $68.7 million in the three months ended September 28, 2024, from $87.4 million in the corresponding period of 2023. Net income available to Charles River Laboratories International Inc. common shareholders decreased to $226.0 million in the nine months ended September 28, 2024, from $287.5 million in the corresponding period of 2023. The decreases in net income available to common shareholders were due principally to the decreases in operating income described above.
During the nine months ended September 28, 2024, our cash flows from operations were $575.2 million compared with $463.0 million for the same period in 2023. The increase was driven by favorable performance across our revenue related accounts, including collections on trade receivables, deferred revenue, and customer deposits; benefiting cash provided by operations by $46.6 million; lower inventory of $13.8 million primarily due to lower purchases of inventory supporting our Safety Assessment business, and timing of payments to our suppliers and vendors benefiting our cash provided by operations by $7.1 million.

DSA revenue decreased $49.0 million primarily due to decreased revenue in our Safety Assessment business primarily due to declines in volume coupled with a decrease in demand within our Discovery Services business. The impact of a recently divested site related to our Safety Assessment business contributed $1.9 million to the decrease. This was partially offset by the effect of changes in foreign currency exchange rates.
DSA operating income decreased $20.4 million during the three months ended September 28, 2024 compared to the corresponding period in 2023. DSA operating income as a percentage of revenue for the three months ended September 28, 2024 was 20.6%, a decrease of 150 bps from 22.1% for the corresponding period in 2023. Operating income and operating income as a percentage of revenue decreased primarily due to the lower revenue described above, higher severance related to recent restructuring activities, and certain third-party legal costs incurred in connection with the investigations by the U.S. government into the non-human primate supply chain; partially offset by lower site consolidation and impairment charges associated with a Discovery Services site closure which occurred in 2023.

Interest income for the three months ended September 28, 2024 was $1.5 million, an increase of $0.2 million, or 11.3%, driven primarily from higher interest rates and interest earning asset balances.
Interest expense for the three months ended September 28, 2024 was $30.3 million, a decrease of $3.5 million, or 10.2%, compared to $33.7 million in the corresponding period in 2023. The decrease was due primarily to lower debt balances as we continue to pay down on our revolving credit facility.
Other income, net for the three months ended September 28, 2024 was $2.6 million, an increase of $8.9 million, or 141.4% compared to Other expense, net of $6.3 million for the corresponding period in 2023.

RMS revenue increased $28.6 million primarily driven by an increase in large research model product revenue, principally due to the recent acquisition of Noveprim, which contributed $30.0 million, and an increase in small research models product revenues across all geographic areas; partially offset by lower Cell Solutions product revenue and Insourcing Solutions services revenue.
RMS operating income decreased $17.0 million compared to the corresponding period in 2023. RMS operating income as a percentage of revenue for the nine months ended September 28, 2024 was 16.1%, a decrease of 360 bps from 19.7% for the corresponding period in 2023. Operating income and operating income as a percentage of revenue decreased primarily due to

DSA revenue decreased $141.9 million primarily due to decreased revenue in our Safety Assessment and Discovery Services businesses due to decreased volume and the impact of a recently divested site related to our Safety Assessment business contributed $7.1 million to the decrease; partially offset by the effect of changes in foreign currency exchange rates.
DSA operating income decreased $100.1 million compared to the corresponding period in 2023. DSA operating income as a percentage of revenue for the nine months ended September 28, 2024 was 20.5%, a decrease of 360 bps from 24.1% for the corresponding period in 2023. Operating income and operating income as a percentage of revenue decreased primarily due to the lower revenue described above, higher severance related to recent restructuring activities, an adjustment to contingent consideration associated with the acquisition of Noveprim, and certain third-party legal costs incurred in connection with the investigations by the U.S. government into the non-human primate supply chain; partially offset by lower site consolidation and impairment charges compared to the corresponding period in 2023.

Unallocated corporate costs consist of selling, general and administrative expenses that are not directly related or allocated to the reportable segments. The increase in unallocated corporate costs of $30.5 million, or 18.4%, compared to the corresponding period in 2023 is primarily related to higher employee compensation and benefits related costs, including severance related to recent restructuring activities and employee fringe related costs, and the absence of positive net settlements recognized on virtual power purchase agreements for the corresponding period in 2023.

Interest income for the nine months ended September 28, 2024 was $6.7 million, an increase of $3.1 million, or 87.0%, driven primarily from higher interest rates.
Interest expense for the nine months ended September 28, 2024 was $98.1 million, a decrease of $5.1 million, or 5.0%, compared to $103.2 million in the corresponding period in 2023. The decrease was due primarily to lower debt balances as we continue to pay down our revolving credit facility.
Other income, net for the nine months ended September 28, 2024 was $6.2 million, an increase of $18.4 million, or 150.7%, compared to Other expense, net of $12.2 million for the corresponding period in 2023. The increase was due primarily to venture capital investment gains of $8.4 million as compared to losses of $14.3 million in the corresponding period in 2023.

Income tax expense for the nine months ended September 28, 2024 was $70.9 million, a decrease of $10.3 million compared to $81.2 million for the corresponding period in 2023. Our effective tax rate was 22.9% for the nine months ended September 28, 2024 compared to 21.8% for the corresponding period in 2023. The increase in our effective tax rate in the nine months ended September 28, 2024 compared to the corresponding period in 2023 was primarily attributable to deferred tax impact of enacted tax law changes, as well as decreased tax benefits from stock-based compensation deductions in the nine months ended September 28, 2024, offset by jurisdictional earnings mix.
Our global operations make the effective tax rate sensitive to significant tax law changes. Several countries where we operate have enacted legislation implementing the Organization for Economic Cooperation and Development’s (OECD) international tax framework, including the Pillar II global minimum tax rate with effect from January 1, 2024 or later. We continue to monitor future legislation on Pillar II, however, the Pillar II associated tax expense accrued for the nine months ended September 28, 2024, is not material to the unaudited consolidated financial statements.

Liquidity and Capital Resources
Liquidity and Cash Flows
We currently require cash to fund our working capital needs, capital expansion, acquisitions, debt payments, lease, venture capital investment, restructuring initiatives, and pension obligations. Our principal sources of liquidity have been our cash flows from operations supplemented by long-term borrowings. Based on our current business plan, we believe that our existing funds, when combined with cash generated from operations and our access to financing resources, are sufficient to fund our operations for the foreseeable future.

Net cash provided by operating activities$575,215 $462,955 
Net cash provided by cash flows from operating activities represents the cash receipts and disbursements related to all of our activities other than investing and financing activities. Operating cash flow is derived by adjusting our net income for (1) non-cash operating items such as depreciation and amortization, stock-based compensation, and other financing costs, deferred income taxes, gains and/or losses on venture capital and strategic equity investments, gains and/or losses on divestitures, contingent consideration, as well as (2) changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in our results of operations.
For the nine months ended September 28, 2024, compared to corresponding period in 2023, the increase in net cash provided by operating activities was primarily driven by favorable performance across our revenue related accounts, including collections on trade receivables, deferred revenue, and customer deposits; benefiting cash provided by operations by $46.6 million; lower inventory of $13.8 million primarily due to lower purchases of inventory supporting our Safety Assessment business, and timing of payments to our suppliers and vendors benefiting our cash provided by operations by $7.1 million.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
For the nine months ended September 28, 2024, cash used in investing activities was primarily driven by capital expenditures, an immaterial asset acquisition, and net purchases and sales in investments related to certain venture capital and strategic equity investments. The Company experienced declines in capital expenditures for the nine months ended September 28, 2024 as compared to the same period in 2023, primarily as a result of disciplined spend management in light of the global economic environment.
For the nine months ended September 30, 2023, cash used in investing activities was primarily driven by capital expenditures to support the growth of the business, the acquisition of SAMDI, and net purchases and sales of investments related to certain venture capital and strategic equity investments.

Financing activities primarily consist of the proceeds and repayments of debt and certain equity related transactions including treasury stock purchases and employee stock option exercises. For the nine months ended September 28, 2024, net cash used in financing activities was primarily driven by the following activity:
•Net repayments of $346.2 million towards our Credit Facility
•Treasury stock purchases of $100.7 million associated with our stock repurchase program and $18.4 million due to the netting of common stock upon vesting of stock-based awards in order to satisfy individual statutory tax withholding requirements
•Net proceeds from exercises of employee stock options of $23.1 million
•Net dividend payments to noncontrolling interest holders of $14.5 million
For the nine months ended September 30, 2023, net cash used in financing activities was primarily driven by the following activity:
•Net repayments of $195 million towards our Credit Facility
•Treasury stock purchases of $24.0 million made due to the netting of common stock upon vesting of stock-based awards in order to satisfy individual statutory tax withholding requirements
•Net proceeds from exercises of employee stock options of $19.7 million
Financing and Market Risk
We are exposed to market risk from changes in interest rates and currency exchange rates, which could affect our future results of operations and financial condition. We manage our exposure to these risks through our regular operating and financing activities.

The Credit Facility has a maturity date of April 2026, with no required scheduled payment before that date. The interest rates applicable to the Credit Facility are equal to (A) for revolving loans denominated in U.S. dollars, at our option, either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.50%, or (3) the one-month adjusted term SOFR rate plus 1%) or the adjusted term SOFR rate, (B) for revolving loans denominated in euros, the adjusted EURIBOR rate and (C) for revolving loans denominated in sterling, the daily simple SONIA rate, in each case, plus an interest rate margin based upon our leverage ratio.
We have an interest rate swap with a notional amount of $500 million to manage interest rate fluctuation related to our floating rate borrowings under the Credit Facility, at a fixed rate of 4.65% on our swap maturing November 2, 2024. We have not entered into any additional interest rate swap contracts.
Our off-balance sheet commitments related to our outstanding letters of credit as of September 28, 2024 and December 30, 2023 were $21.2 million and $21.6 million, respectively.
Foreign Currency Exchange Rate Risk
We operate on a global basis and have exposure to foreign currency exchange rate fluctuations for our financial position, results of operations, and cash flows.
While the financial results of our global activities are reported in U.S. dollars, our foreign subsidiaries typically conduct their operations in their respective local currency. The principal functional currencies of the Company’s foreign subsidiaries are the Euro, British Pound, Canadian Dollar, and Mauritian Rupee. During the nine months ended September 28, 2024, the most significant drivers of foreign currency translation adjustment the Company recorded as part of Other comprehensive income (loss) were the British Pound, Mauritian Rupee, Euro, and Canadian Dollar.
Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our financial position, results of operations, and cash flows. As the U.S. dollar strengthens against other currencies, the value of our non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally decline when reported in U.S. dollars. The impact to net income as a result of a U.S. dollar strengthening will be partially mitigated by the value of non-U.S. expenses, which will decline when reported in U.S. dollars. As the U.S. dollar weakens versus other currencies, the value of the non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally increase when reported in U.S. dollars. For the nine months ended September 28, 2024, our revenue would have decreased by $96.8 million, and our operating income would have decreased by $5.8 million, if the U.S. dollar exchange rate had strengthened by 10%, with all other variables held constant.
We attempt to minimize this exposure by using certain financial instruments in accordance with our overall risk management and our hedge policy. We do not enter into speculative derivative agreements.
Repurchases of Common Stock
On August 2, 2024, our Board of Directors approved a stock repurchase authorization of $1 billion. This authorization fully replaces a prior stock repurchase authorization of $1.3 billion that had $129.1 million remaining when it was terminated and we did not repurchase any shares under the prior program during the nine months ended September 28, 2024.
During the three and nine months ended September 28, 2024, we repurchased 0.5 million shares of common stock for $100.7 million under the new stock repurchase program. As of September 28, 2024, we had $899.3 million remaining on the current authorized stock repurchase program.
Additionally, our stock-based compensation plans permit the netting of common stock upon vesting of restricted stock, restricted stock units, and performance share units in order to satisfy individual statutory tax withholding requirements. During the nine months ended September 28, 2024, we acquired 0.1 million shares for $18.4 million through such netting.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements prepared in accordance with generally accepted accounting principles in the U.S. The preparation of these financial statements requires us to make certain estimates and assumptions that may affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses during the reported periods, and the related disclosures. These estimates and assumptions are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates could occur in the future. We base our estimates on our historical experience, trends in the industry, and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from our estimates under different assumptions or conditions.
We believe that the application of our accounting policies, each of which require significant judgments and estimates on the part of management, are the most critical to aid in fully understanding and evaluating our reported financial results. Our significant accounting policies are more fully described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for fiscal year 2023 as filed with the SEC on

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
February 14, 2024. There have been no changes in the Company’s critical accounting policies during the nine months ended September 28, 2024.
Recent Accounting Pronouncements
For a discussion of recent accounting pronouncements please refer to Note 1, “Basis of Presentation,” in this Quarterly Report on Form 10-Q. Other than as discussed in Note 1, “Basis of Presentation,” we did not adopt any other new accounting pronouncements during the nine months ended September 28, 2024 that had a significant effect on our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
The Company’s exposure to market risk from changes in interest rates and currency exchange rates has not changed materially from its exposure discussed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 30, 2023 as filed with the SEC on February 14, 2024. Our interest rate and currency exchange rate risks are fully described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” of our Annual Report on Form 10-K for fiscal year 2023 and in Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” herein.
Item 4. Controls and Procedures
(a)  Evaluation of Disclosure Controls and Procedures
Based on their evaluation, required by paragraph (b) of Rules 13a-15 or 15d-15, promulgated by the Securities Exchange Act of 1934, as amended (Exchange Act), the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, are effective, at a reasonable assurance level, as of September 28, 2024, to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.
(b) Changes in Internal Controls Over Financial Reporting
There were no material changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of the Exchange Act Rules 13a-15 or 15d-15 that occurred during the quarter ended September 28, 2024 that materially affected, or were reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain shipments in the United States. The carrying value of the inventory related to these shipments is approximately $27 million as of September 28, 2024, which reflects the value of the shipments in accordance with the Company’s inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena and additional inquiries, primarily related to the sourcing of non-human primates and related disclosures, and the Company is cooperating with these requests. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or resolved. The Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities.
A putative securities class action (Securities Class Action) was filed on May 19, 2023 against the Company and a number of its current/former officers in the United States District Court for the District of Massachusetts. On August 31, 2023, the court appointed the State Teachers Retirement System of Ohio as lead plaintiff. An amended complaint was filed on November 14, 2023 that, among other things, included only James Foster, the Chief Executive Officer and David R. Smith, the former Chief Financial Officer as defendants along with the Company. The amended complaint asserts claims under §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 (the Exchange Act) on behalf of a putative class of purchasers of Company securities from May 5, 2020 through February 21, 2023, alleging that certain of the Company’s disclosures about its practices with respect to the importation of non-human primates made during the putative class period were materially false or misleading. On July 1, 2024, the court dismissed the complaint, denied the plaintiff’s informal request for leave to amend, and entered judgment for defendants. On July 30, 2024 the plaintiff filed a notice of appeal in the United States Court of Appeals for the First Circuit. While the Company cannot predict the final outcome of this matter, it believes the class action to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.
On November 8, 2023, a stockholder filed a derivative lawsuit in the U.S. District Court of the District of Delaware asserting claims on the Company’s behalf against the members of the Company’s Board of Directors and certain of the Company’s current/former officers (James Foster, the Chief Executive Officer; David R. Smith, the former Chief Financial Officer; and Flavia Pease, the current Chief Financial Officer). The complaint alleges that the defendants breached their fiduciary duties to the Company and its stockholders because certain of the Company’s disclosures about its practices with respect to the importation of non-human primates were materially false or misleading. The complaint also alleges that the defendants breached their fiduciary duties by causing the Company to fail to maintain adequate internal controls over securities disclosure and compliance with applicable law and by failing to comply with the company’s Code of Business Conduct and Ethics. The lawsuit is currently stayed by agreement of the parties pending further developments in the Securities Class Action pending in the United States Court of Appeals for the First Circuit. On August 2, 2024, a different stockholder filed a lawsuit in the U.S. District Court of Delaware asserting similar derivative claims on the Company’s behalf against members of the Company’s current and former Board of Directors and the same current/former officers based on similar allegations of purportedly misleading disclosures and non-compliance with legal rules and ethics standards in respect of the importation of non-human primates, as well as insider-trading claims against certain of the defendants. The lawsuit is currently stayed by agreement of the parties pending further developments in the Securities Class Action pending in the United States Court of Appeals for the First Circuit. While the Company cannot predict the outcome of these matters, it believes the derivative lawsuits to be without merit

and plans to vigorously defend against them. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with these matters.
