What Happened?

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, Avantor’s stock price fell $2.57, or 16.6%, to close at $12.93 per share on April 25, 2025, thereby injuring investors.

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, Avantor’s stock price fell $2.08, or 15.5%, to close at $11.36 per share on August 1, 2025.

Then, 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, Avantor’s stock price fell $3.50, or 23.2%, to close at $11.58 per share on October 29, 2025, thereby injuring investors further.
