Illumina, Inc. (NASDAQ: ILMN) Securities Fraud Class Action

Case Background:
This is a federal securities fraud class action lawsuit on behalf of those who purchased or otherwise acquired Illumina, Inc. (“Illumina”) (NASDAQ: ILMN) securities between September 21, 2020 and November 9, 2023, inclusive (the “Class Period”).

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 Illumina’s business, operations, and prospects. Specifically, Defendants failed to disclose that: (1) certain of the company’s insiders had personal financial motives for acquiring GRAIL; (2) contrary to Illumina’s attempts to discount Icahn’s criticism, Icahn had accurately concluded that insiders’ interests did not align with the company’s best interests; and (3) as a result of the foregoing, Defendants’ positive statements about the company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.

Current Status of Case:
On December 11, 2025, Defendants filed Motions to Dismiss the Amended Complaint. The Motions have been briefed and are pending decision before the Court. This action is ongoing.
