NH 2021 Annual Report

In April 2018, a putative shareholder derivative action captioned Shen v. Soon-Shiong was filed in U.S. District Court for the District of Delaware. In November 2018, a putative shareholder derivative action captioned Manuel v. Soon-Shiong was filed in the U.S. District Court for the District of Delaware. The complaints contain allegations similar to those in the Deora action but also asserted causes of action on behalf of NantHealth against various of the Company’s current or former executive officers and directors for alleged breaches of fiduciary duty and unjust enrichment, as well as alleged violations of the federal securities laws based on alleged misstatements or omissions in the Company’s 2017 proxy statement. The Company is named solely as a nominal defendant. On January 15, 2019, the Shen and Manuel actions were consolidated in a case captioned In re NantHealth, Inc. Stockholder Derivative Litigation. The parties agreed to stay the consolidated case pending a decision on defendants’ motion to dismiss in the derivative action in the Delaware Court of Chancery. The stay was lifted after the Delaware Court of Chancery's January 14, 2020 decision granting in part and denying in part the motion to dismiss. On October 5, 2020, an amended consolidated complaint was filed which brings claims only against Dr. Soon-Shiong for alleged violations of the federal securities laws and breach of fiduciary duty based on alleged misstatement or omissions in the Company’s 2017 and 2018 proxy statements and other public filings. On December 4, 2020, defendant moved to dismiss the amended complaint. On February 2, 2021, plaintiffs filed an answering brief in opposition to defendant’s motion to dismiss. On March 18, 2021, defendant filed a reply brief in further support of his motion to dismiss the amended complaint. On May 12, 2021, the court issued an order dismissing the amended complaint with prejudice. NantHealth, Inc.
