Case Background:
This is a federal securities fraud class action lawsuit on behalf of investors who purchased or otherwise acquired Avantor, Inc. (“Avantor”) (NYSE: AVTR) common stock between March 5, 2024 and February 10, 2026, inclusive (the “Class Period”).
Avantor, a Delaware corporation with its principal executive offices in Radnor, Pennsylvania, provides scientific products and services for customers in biotechnology, pharmaceuticals, healthcare, education, government, and other industries.
The Class Period begins on March 5, 2024, when Defendant Michael Stubblefield, then the company’s President and Chief Executive Officer, represented Avantor at a TD Cowen healthcare industry conference. In response to an analyst’s question about Avantor’s competitive positioning in its Laboratory Solutions business, Stubblefield emphasized that Avantor’s competitive position “[c]ontinues to be strong,” further representing that “we continue to have confidence in the positioning [of] a lot of investments in our digital capabilities there to make it more efficient for our customers to engage with us…” and that “the traffic to our sites relative to our competitors is a nice indicator for our business.”
During the Class Period, Defendants misled investors by falsely touting the company’s competitive positioning and downplaying the effects of increased competition. For example, during an earnings call on July 26, 2024, in response to an analyst’s question about whether Avantor was losing share to a competitor, Defendant Stubblefield, assured investors that Avantor’s “lab business stacks up well against every number that certainly that we’ve seen,” that “we continue to enhance our position,” and that “we’re really confident in our value proposition and our competitive position.” Likewise, Defendants repeatedly pointed to Avantor’s purported competitive advantages, such as its digital capabilities, as evidence that the company would continue to enjoy strong competitive positioning.
The complaint alleges that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts, about the company’s business and operations. Specifically, Defendants misrepresented 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 of the foregoing, Defendants’ statements about the company’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.
Current Status of Case:
On April 24, 2026, the Lead Plaintiff filed the Amended Complaint. This action is ongoing.
