Avantor, Inc. (NYSE: AVTR)

This lawsuit is for anyone who acquired securities in Avantor, Inc. (NYSE: AVTR) from March 5, 2024 through October 28, 2025.

The lawsuit alleges that the Company and certain of its executives violated federal law. Specifically, the lawsuit alleges that, throughout the time period mentioned above, the Company misled investors regarding its financial condition. More specifically, the lawsuit alleges that the Company misled investors by failing to timely reveal that the Company was experiencing negative effects from increased competition.

On April 25, 2025, Avantor released its first quarter 2025 financial results, missing consensus estimates and cutting guidance for the remainder of 2025, citing “the impact of increased competitive intensity.” Additionally, the Company announced that its President and Chief Executive Officer would be stepping down from his roles. On this news, the price of the Company’s stock dropped precipitously on unusually heavy trading volume. Then, on August 1, 2025, Avantor released its second quarter 2025 financial results, once again missing estimates and revealing a year-over-year decrease in net sales, and further reducing the Company’s 2025 guidance due to “increased competitive intensity,” stating that it did not expect improvement for the remainder of 2025. On this news, the price of the Company’s stock again dropped precipitously on unusually heavy trading volume. Finally, on October 29, 2025, Avantor released disappointing third quarter 2025 financial results, including -5% organic revenue growth and a net loss of $712 million, which the Company attributed primarily to a non-cash goodwill impairment charge of $785 million due in part to “competitive pressures” that had “meaningfully impacted” the Company’s margins, and further revealed that the Company had lost several large accounts. On this news, the price of the Company’s stock again dropped precipitously on unusually heavy trading volume.
