Item 8.01 Other Events.
Effective August 21, 2025, Illumina, Inc. (the “Company”) entered into a Release Agreement with the plaintiffs and all named defendants reflecting the terms of the settlement of the litigation captioned Icahn Partners LP, et al., v. Francis DeSouza, et al., C.A. No. 2023-1045-PAF (the “Action”) in the Court of Chancery of the State of Delaware (the “Court”), relating to the Company’s acquisition of GRAIL, Inc. The Defendants Francis deSouza, John Thompson, Frances Arnold, Caroline Dorsa, Robert Epstein, Scott Gottlieb, Gary Guthart, Philip Schiller and Susan Siegel (the “Defendants”) continue to deny each and all of the claims and contentions alleged by plaintiffs in the litigation and expressly deny any fault, wrongdoing or liability. The Release Agreement provides that, in exchange for mutual releases but no payment by any party, this Action shall be dismissed with prejudice as to the Plaintiffs only and without prejudice to any other Illumina stockholders. The Defendants and the Company agreed to the settlement solely to avoid the burden, expense and uncertainty of further litigation. Since the litigation is brought on behalf of the Company, the Company is named as a “Nominal Defendant”.
The litigation was settled and the parties seek to dismiss the Action, subject to the approval of the Court. The Court will hold a hearing on the proposed dismissal on November 2, 2026, at 1:30 p.m. Eastern time. A copy of the Notice of Pendency of the Action, Proposed Dismissal of the Action, and Dismissal Hearing is filed as Exhibit 99.1 to this Current Report on Form 8-K.
