ROSEN Alerts Avantor Shareholders: Key Deadline Dec. 29, 2025 for AVTR Class Action

Rosen Law Firm — a global investor‑rights law firm — has issued a reminder to anyone who bought common stock of Avantor, Inc. (NYSE: AVTR) between March 5, 2024 and October 28, 2025 (the “Class Period”) that they may be eligible to join a securities class‑action lawsuit. If you purchased Avantor shares during that time, you could qualify for compensation under a contingency‑fee arrangement — meaning you pay nothing out of pocket. To participate (or to seek the role of lead plaintiff), you must file a motion with the court by December 29, 2025. The lawsuit alleges Avantor and its executives misled investors by overstating the company’s competitive position and failing to disclose mounting competitive pressures, rendering prior statements about business prospects materially false or lacking a reasonable basis. To join the class action or request more info, investors can submit a form on Rosen Law Firm’s website or contact attorney Phillip Kim via phone or email — all as outlined in the firm’s official notice. #Avantor #AVTR #ClassAction #RosenLawFirm #SlimScan #GrowthStocks #CANSLIM
