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, and (3) the derivative lawsuit filed against members of the Board of Directors and certain current/former officers on November 8, 2023; 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, particularly with respect to our CDMO business); the impact of specific actions intended to improve overall operating efficiencies and profitability (and our ability to accommodate future demand with our infrastructure), including gains and losses attributable to businesses we plan to close, consolidate, divest or repurpose and the impact of operations and cost structure alignment efforts (including as estimated on an annualized basis); our expectations with respect to our study cancellation rates and the impact of such cancellations; 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.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements are unaudited and have been prepared by Charles River Laboratories International, Inc. (the Company) in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). The year-end condensed consolidated balance sheet data was derived from the Company’s audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for fiscal year 2023. 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 in the annual 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.

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 $374.8 million, which includes $144.6 million additional cash paid for the 41% equity interest, elimination of historical activity and intercompany balances of $198.8 million which includes a remeasurement gain on the 49% equity investment of $103.2 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 $13.8 million. 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 sheet. 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 $0.2 million and $0.8 million for the three months ended March 30, 2024 and April 1, 2023, respectively, which was primarily included in Selling, general and administrative expenses within the unaudited condensed consolidated statements of income.

Contingent Consideration

The following table provides a rollforward of the contingent consideration related to the Company’s acquisitions.

	Three Months Ended
	March 30, 2024		April 1, 2023
	(in thousands)
Beginning balance	$	33,265	$	13,431
Payments	—		(2,711)
Total gains or losses (realized/unrealized):
Foreign currency translation	—		(177)
Ending balance	$	33,265	$	10,543

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 million, of which the value accrued as of March 30, 2024 is $33 million as the probability of achieving the maximum target is estimated to be 60%. The volatility and weighted average cost of capital is approximately 7% and 9%, 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 has 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. The book value and fair value of the Company’s Senior Notes is summarized below:

	March 30, 2024				December 30, 2023
	Book Value		Fair Value		Book Value		Fair Value
	(in thousands)

Redeemable Noncontrolling Interests

Through March 30, 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, the 10% noncontrolling interest holders may receive a dividend disproportionate to their equity ownership, of which the fair value of $8 million as of the acquisition date was recorded within the redeemable noncontrolling interest. Through March 30, 2024, incremental dividends based on Noveprim statutory net income attributed to the redeemable noncontrolling interest holders of $5.2 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 March 30, 2024, the redemption value of $45.8 million exceeded both the carrying value and fair value, resulting in both an adjustment to additional paid in capital of $1.7 million and an adjustment to retained earnings of $0.4 million, respectively.

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 has the right to purchase, and the noncontrolling interest holders have the right to sell, the remaining 10% equity interest at its appraised value. The redemption value is 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 is 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
