Overview
- Rosen Law Firm, Bernstein Liebhard, The Gross Law Firm, Frank R. Cruz, Robbins LLP, and Faruqi & Faruqi announced filings or investigations and are soliciting Avantor shareholders.
- The putative class spans purchases of Avantor stock from March 5, 2024 through October 28, 2025, according to the complaints.
- Plaintiffs allege Avantor overstated its competitive strength and failed to disclose negative effects from rising competition, rendering prior statements misleading.
- The suits cite Oct. 29, 2025 disclosures of −5% organic revenue growth, a $785 million goodwill impairment tied in part to competitive pressures, and a $712 million net loss that preceded a share decline of more than 23%.
- No class has been certified and the claims remain unproven, with investors able to move for lead-plaintiff appointment by December 29, 2025.
