Rosen urges Avantor shareholders to act before Dec. 29 deadline

A leading investor‑rights firm, The Rosen Law Firm, is encouraging anyone who purchased common stock of Avantor, Inc. (NYSE: AVTR) between March 5, 2024 and October 28, 2025 to secure legal counsel before the upcoming lead‑plaintiff deadline on December 29, 2025. The class action lawsuit — already filed on behalf of these investors — alleges that Avantor made false or misleading statements about its competitive position and downplayed mounting competitive pressure. As a result, when the truth emerged (including weak sales and reduced guidance in 2025), Avantor shares reportedly dropped sharply — triggering potential losses to shareholders who bought during the “Class Period.” Investors are told they may be entitled to compensation and can participate without paying upfront fees or costs under a contingency‑fee arrangement. To explore joining the case — or to apply to become lead plaintiff — interested shareholders should contact the Rosen Law Firm by the December 29 deadline. #Avantor #AVTR #ClassAction #InvestorAlert #SlimScan #GrowthStocks #CANSLIM
