Introduction to the Avantor Class Action Lawsuit
- Who is Affected? Purchasers or acquirers of Avantor, Inc. (NYSE: AVTR) (“Avantor” or the “Company”) common stock between March 5, 2024, and October 28, 2025, inclusive (the “Class Period”).
- The Problem: The Avantor class action lawsuit alleges the defendant made false and misleading statements driving the stock price artificially up until the truth emerged and the stock plummeted and shareholders who purchased during the relevant time period and suffered a loss are entitle to damages
- Your Action: You may be eligible to recover your losses.
- Deadline to Lead: The deadline to apply to be Lead Plaintiff is December 29, 2025.
How Securities Class Actions Work
- A lead plaintiff files the lawsuit. Usually, an individual or institutional investor who suffered a large financial loss acts as the lead plaintiff, representing the interests of all investors who were harmed. The lawsuit is typically brought by a law firm that specializes in securities litigation.
- The lawsuit proceeds through the court. The case is filed under federal or state securities laws, like the Securities Exchange Act of 1934. The defendant company may file a motion to dismiss the case. If the case proceeds, both sides will enter a lengthy discovery phase to gather evidence.
- Most cases end in a settlement. Rather than going to trial, the company often agrees to pay a sum of money into a common fund to be distributed to the class. The court must approve the fairness of any settlement.
- Claims are administered. If a settlement is reached, a claims administrator is appointed to process claims and distribute funds to eligible investors. The entire process, from filing the complaint to distributing funds, can take several years.
Key Aspects of Securities Fraud Class Actions
- The Fraud: This involves a company or its executives intentionally making false or misleading statements to manipulate the stock market. This can include concealing important information that, if known, would have affected an investor’s decision to buy, sell, or hold the stock.
- The Class Period: This is the timeframe during which the alleged fraud took place. It typically starts when the misleading information is released and ends when the truth is fully disclosed to the public, often leading to a significant drop in the stock price. The class period in the Avantor class action lawsuit is between March 5, 2024, and October 28, 2025.
- Investor Eligibility: To be included, you must have purchased or sold the company’s securities during the class period and suffered an economic loss.
- Lead Plaintiff: A court-approved lead plaintiff represents the entire class, oversees the litigation, and has the authority to approve settlements on behalf of all class members.
- Legal Basis: These lawsuits are based on federal and state securities laws, such as the Securities Act of 1933 and the Securities Exchange Act of 1934.
- Benefits: Class actions give individual investors leverage against large companies and allow them to share the costs of litigation through a contingency-fee arrangement, meaning the lawyers are paid only if the class wins.
- Participation: Investors who are eligible to join the class do not have to join and can “opt out” to pursue their own individual lawsuit, though this requires hiring and paying a private attorney.
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.
Common Types of Misconduct
- Securities fraud class actions can arise from various types of misconduct by a company, its officers, or others involved in the sale of its securities, including:
- Making false or misleading statements in SEC filings, prospectuses, or earnings announcements.
- Overstating a company’s revenues or profits through fraudulent or “creative” accounting.
- Failing to disclose material information that would significantly alter an investor’s view.
- Engaging in market manipulation to artificially inflate or deflate a security’s price.
What Plaintiffs Must Prove
To succeed in a federal securities fraud class action, 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.

- 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.

Allegations in the Avantor Class Action Lawsuit
Overview
- Avantor engages in the provision of mission-critical products and services to customers in the biopharma, healthcare, education and government, advanced technologies, and applied materials industries.
False and Misleading Statements
- The Avantor class action lawsuit further alleges that on April 25, 2025, Avantor announced its first quarter 2025 financial results, reporting weak organic sales in Laboratory Solutions and cut its guidance for 2025.
- Specifically, the company’s CFO, defendant R. Brent Jones, admitted that Avantor had “felt the impact of increased competitive intensity,” resulting in “reduced volumes at a handful of customers,” the complaint alleges.
- Avantor further announced, allegedly, that defendant Michael Stubblefield would be stepping down from his roles as President and Chief Executive Officer upon the appointment of a successor.
- On this news, the price of Avantor shares fell by more than 16%, the complaint alleges.
The Avantor investor class action further alleges that August 1, 2025, Avantor reported disappointing second quarter 2025 financial results and reduced the company’s full-year guidance, including its guidance for growth in Laboratory Solutions.
CFO Jones attributed the weakening outlook for Avantor’s Laboratory Solutions business to “increased competitive intensity,” admitted that Avantor did not expect the competitive environment to “chang[e] materially” in the remainder of 2025, and projected that the weak Laboratory Solutions performance would persist, the complaint alleges.
On this news, the price of Avantor shares fell by more than 15%, the complaint alleges.
Corrective Disclosure
Finally, the Avantor shareholder lawsuit alleges that on October 29, 2025, Avantor reported weak financial results for the third quarter of 2025, including 5% decreases in organic revenue growth both overall and in Avantor’s Laboratory Solutions business – revealing that defendants’ recent assurances of “careful” third quarter projections of -4% to -2% growth were false.
On this news, the price of Avantor shares fell by more than 23%, the complaint alleges.

The Eligibility Criteria for Lead Plaintiff Appointment in the Avantor Lawsuit
To be eligible for appointment as the lead plaintiff in the Avantor Class Action Lawsuit, an investor must meet the following criteria:
- Securities Acquisition: The investor must have been purchasers or acquirers of Avantor, Inc. (NYSE: AVTR) (“Avantor” or the “Company”) common stock between March 5, 2024, and October 28, 2025, inclusive (the “Class Period”).
