Why is Charles River Laboratories International, Inc. (CRL) stock moving?

Charles River beat Q3 2026 estimates on Nov 4, with adjusted EPS of $3.09 against $2.97 and sales of $982.7M against $958.7M. Full-year adjusted EPS guidance was widened to $11.35-$11.55, around the $11.38 estimate, while sales guidance rose to $3.940B-$3.960B. Management does not expect a pricing benefit until at least H2 2027. The stock still fell from a $349.90 open to a $326.29 close on Nov 4, then hit a 30-day low of $313.02 on Nov 5 on heavy volume of about 1.66M shares. Analysts responded with price target increases to $352-$400 (RBC $352, Barclays $375, Jefferies $385, UBS $387, Evercore $400), with UBS maintaining Buy and Evercore Outperform. On Nov 9 Charles River agreed to buy Frontage's bioanalysis and DMPK operations for $470M in cash plus up to $75M in contingent payments, expected to close in H1 2027 subject to approvals. An analyst called it an attractive strategic addition, and the stock rose to $353.34 that day. The close on Nov 10 was $345.80 on lower volume of about 822K shares, roughly 9% below the 30-day high of $379.63 from Oct 29. The evidence points to fundamentals and analyst sentiment that lean positive, while the stock's post-earnings reaction and the deal's cash cost and pending approvals keep the picture mixed.

Charles River Laboratories, based in Wilmington, Massachusetts, sells research services and products that drug companies use in the early, pre-human stages of drug development. It is one of the world's largest preclinical contract research organizations (CROs) and a major supplier of research animal models. That gives it a central place in early-stage drug safety testing.

Research Models and Services (RMS), about 20%, breeds and sells research animals such as rodents and provides related services. Manufacturing Solutions, about 18%, includes microbial testing (for example, Endosafe kits that test drugs for bacterial contamination) and biologics testing. In May 2026 the company sold some businesses, including its contract drug manufacturing (CDMO) operation. Quarterly revenue is roughly $1 billion.
