On April 25, 2025, Avantor reported disappointing first quarter 2025 financial results, cut its guidance for 2025, and announced that Michael Stubblefield would be stepping down from his roles as President and Chief Executive Officer. Avantor's management attributed its weak performance and outlook to "the impact of increased competitive intensity."

On this news, Avantor's stock price fell $2.57 per share, or 16.5%, to close at $12.93 per share on April 25, 2025.

Then, on August 1, 2025, Avantor reported disappointing second quarter 2025 financial results, including a year-over-year decrease in net sales, and further reduced the Company's 2025 guidance-now projecting organic revenue growth of -2% to 0%. Avantor's management again attributed the Company's lackluster results and outlook to "increased competitive intensity" and further admitted that Avantor did not expect the competitive environment to materially improve in the remainder of 2025.

On this news, Avantor's stock price fell $2.08 per share, or 15.48%, to close at $11.36 per share on August 1, 2025.

Then, on October 29, 2025, Avantor reported weak third quarter 2025 financial results, including -5% organic revenue growth and a net loss of $712 million, which management primarily attributed to a non-cash goodwill impairment charge of $785 million. Avantor's management said that the impairment charge was necessary due in part to "competitive pressures" that had "meaningfully impacted" Avantor's margins and further disclosed that the Company had lost several large accounts.

On this news, Avantor's stock price fell $3.50 per share, or 23.21%, to close at $11.58 per share on October 29, 2025.
