Rosen Law Firm reminds Avantor, Inc. investors who bought common stock between March 5, 2024 and October 28, 2025 of the December 29, 2025 lead plaintiff deadline. The lawsuit alleges defendants overstated Avantor’s competitive position and failed to disclose mounting competitive pressures, making statements about the company’s business and prospects misleading; investors allegedly suffered damages when details reached the market. No class has been certified. Investors can choose their own counsel, seek to be lead plaintiff by the deadline, or remain absent.
