COURT United States District Court for the Southern District of California 
CASE NUMBER 23-cv-02082
JUDGE The Hon. Linda Lopez
CLASS PERIOD  September 21, 2020 through November 9, 2023


A class action lawsuit has been filed on behalf of those who purchased or acquired Illumina, Inc. (“Illumina”) (NASDAQ: ILMN) securities between September 21, 2020 and November 9, 2023, both dates inclusive (the “Class Period”). 
The complaints allege 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 to investors 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.
