The filed complaint alleges that defendants made materially false and/or misleading statements and/or 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.
