Item 2.02 Results of Operations and Financial Condition

Charles River Laboratories International, Inc. ("Charles River" or the "Company") will be presenting at the J.P. Morgan 44th Annual Healthcare Conference (the "J.P. Morgan Conference") on Tuesday, January 13, 2026, at approximately 1:30 p.m. Eastern time. During this presentation, management of the Company intends to present an overview of the Company’s strategic focus, business developments and recent trends. Included in this overview will be a statement that demand trends for the Company's Discovery and Safety Assessment (DSA) business have continued to improve throughout the second half of 2025, resulting in a preliminary estimate for the DSA net book-to-bill of approximately 1.1x in the fourth quarter of 2025. This statement may be considered an estimate of preliminary fourth quarter 2025 financial information. The Company is continuing to review its 2025 financial and operating results and actual results may differ materially from those contained herein. In particular, the preliminary financial information could vary from the above expectations based on the completion of the Company's audited financial results.

In advance of the conference presentation, the Company has posted a slide presentation on the Investor Relations section of the Company’s website at http://ir.criver.com (the “Slide Presentation”). The Slide Presentation is not incorporated herein by reference.

Item 7.01 Regulation FD Disclosure

The Slide Presentation prepared in connection with the J.P. Morgan Conference also includes the following statements as to recent client demand trends and preliminary 2026 outlook:

•Q4 DSA Trends: DSA demand trends continued to improve throughout the second half of 2025, resulting in preliminary DSA net book-to-bill of approximately 1.1x in the fourth quarter of 2025 –Improving trends during the second half of 2025 were primarily driven by small and mid-sized biotech clients, while global biopharma net bookings also increased in in the fourth quarter of 2025

▪2026 Revenue: Expect top end of 2026 guidance ranges for organic revenue growth rate will be at least flat for both consolidated outlook and for the DSA segment –Cautiously optimistic that favorable DSA demand KPIs will continue into 2026, resulting in return to revenue growth in the second half of 2026 –Expected improvement in Manufacturing organic revenue growth will be offset by anticipated RMS headwinds from timing of NHP shipments and CRADL occupancy –Foreign exchange (FX) expected to be an incremental benefit of 100-150 bps to reported revenue growth in 2026

▪2026 Non-GAAP Operating Margin: Incremental cost savings in 2026 totaling >$100M will help to offset annual cost inflation until revenue growth reinvigorates - This outlook does not yet reflect the potential impact of the K.F. (Cambodia) Ltd. and PathoQuest SAS acquisitions or planned divestitures, which would collectively benefit the non-GAAP operating margin once the transactions are completed

About Charles River Laboratories International Inc. (CRL) Earnings

This page provides Charles River Laboratories International Inc. (CRL) earnings call transcripts from SEC 8-K filings along with AI-powered predictions for post-earnings price movements. Our machine learning models analyze historical earnings data, pre-earnings price patterns, volume changes, and volatility to predict 1-day, 5-day, and 20-day returns after each earnings release.

Earnings transcripts are sourced directly from SEC EDGAR filings. Predictions are generated using gradient boosting models trained on CRL's historical earnings reactions. All predicted returns are shown as percentages, and predicted prices are calculated from the closing price at the time of prediction. Past performance does not guarantee future results.
