NEW YORK, Nov. 01, 2025 (GLOBE NEWSWIRE) --

What’s Happening:

  • Bragar Eagel & Squire, P.C., a nationally recognized stockholder rights law firm, announces that a class action lawsuit has been filed against Avantor, Inc. (“Avantor” or the “Company”) (NYSE: AVTR) in the United States District Court for the Eastern District of Pennsylvania on behalf of all persons and entities who purchased or otherwise acquired Avantor common stock between March 5, 2024, and October 28, 2025, both dates inclusive (the “Class Period”). Investors have until December 29, 2025 to apply to the Court to be appointed as lead plaintiff in the lawsuit.

Allegation Details:

  • According to the complaint, defendants failed to disclose that: (1) Avantor's competitive positioning was weaker than defendants had publicly represented; (2) Avantor was experiencing negative effects from increased competition; and (3) as a result, defendants' representations about the Company's business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis.

  • Plaintiff alleges that on October 29, 2025, the Company reported weak third quarter 2025 financial results, including -5% organic revenue growth (below defendants' August guidance), and a net loss of $712 million, which defendants primarily attributed to a non-cash goodwill impairment charge of $785 million. Defendants revealed that the impairment charge was necessary due in part to "competitive pressures" that had "meaningfully impacted" the Company's margins and further admitted that the Company had lost several large accounts. On this news, the price of Avantor common stock declined $3.50 per share, or more than 23%, from a close of $15.08 per share on October 28, 2025, to close at $11.58 per share on October 29, 2025.

Next Steps:

  • If you purchased or otherwise acquired Avantor shares and suffered a loss, are a long-term stockholder, have information, would like to learn more about these claims, or have any questions concerning this announcement or your rights or interests with respect to these matters, please contact Brandon Walker or Marion Passmore by email at investigations@bespc.com, telephone at (212) 355-4648, or by filling out this contact form.
