Lead plaintiff motions for the Avantor class action lawsuit must be filed with the court no later than December 29, 2025.
How it Works
- A lawsuit is initiated by one or more investors, called the “lead plaintiffs,” on behalf of a larger group of investors, or the “class”.
- The “class period” is defined as the specific timeframe during which the alleged fraudulent activity took place. Only those who bought or sold the security during this period are eligible to participate.
- A lead plaintiff is appointed to represent the class. Under the Private Securities Litigation Reform Act (PSLRA), the court will typically appoint the investor with the largest financial interest in the outcome of the case.
- The case is litigated, which may include a lengthy discovery phase for gathering evidence.
- The case can be settled or go to trial. Most class actions are resolved through settlements, which can include cash or stock paid into a common fund for the class. The lead plaintiff and class counsel approve any settlement before it is finalized.
What Plaintiffs Must Prove
To succeed in a federal securities fraud class action, such as the Avantor class action lawsuit, plaintiffs must prove several elements:
- Material misstatement or omission: The company made a false or misleading statement, or failed to disclose a material fact.
- Scienter: The defendant acted with an intent to deceive, manipulate, or defraud.
- Reliance: The plaintiff relied on the misstatement or omission when buying or selling the security. For publicly traded securities, this can be proven through the “fraud-on-the-market” theory, which presumes the market price reflects all public, material information.
- Economic loss: The plaintiff suffered a financial loss.
- Loss causation: The company’s misstatement or omission directly caused the plaintiff’s loss, often demonstrated by a stock price drop after the truth is revealed in a “corrective disclosure”
Benefits for Investors
- Participating in a class action allows investors to pool their resources, which offers leverage they would not have in an individual lawsuit against a large corporation.
- The collective approach also makes it more efficient and cost-effective to pursue legal action, especially for smaller investors.
How to Get Involved
- If you bought a security during the alleged class period and suffered a loss, you are generally automatically included in the class in the Avantor class action lawsuit. You don not have to take any action unless you want to file a claim for recovery later.
- You may be notified of a class action by mail if you are an eligible class member.
- You may be able to become a lead plaintiff by applying within 60 days of the first lawsuit being announced.
- If you believe you may have a claim, you can contact a securities class action law firm for guidance.
