PALO ALTO, Calif., April 05, 2023 (GLOBE NEWSWIRE) -- Scilex Holding Company (Nasdaq: SCLX, “Scilex”), a subsidiary of Sorrento Therapeutics, Inc. (OTC Market: SRNEQ) (“Sorrento”), announced today that the Company’s 2023 Annual Meeting of Stockholders (the “Annual Meeting”) that was scheduled to be held at 9:00 a.m. (Pacific Time) on Thursday, April 6, 2023, has been postponed to April 17, 2023 at 9:00 a.m. (Pacific Time). Scilex is postponing the Annual Meeting due to the previously announced substantial underreporting of more than 44 million shares of its common stock by brokers, banks and other nominees (collectively, “brokerage firms”) to Broadridge Financial Solutions, Inc., an independent third party that collects and tabulates stockholder votes for the upcoming Annual Meeting, and in response to multiple brokerage firms requesting more time to complete the reporting per court order described below. On April 4, 2023, Sorrento announced that the U.S. Bankruptcy Court for the Southern District of Texas entered an order compelling specified brokerage firms to produce non-privileged written responses to Sorrento providing certain information related to the record and beneficial ownership of Scilex common stock received by Sorrento’s stockholders in connection with Sorrento’s previously announced dividend of 76,000,000 shares of Scilex common stock held by Sorrento. The order was executed in connection with Sorrento’s chapter 11 case, which was filed on February 13, 2023. Scilex anticipates that if the brokerage firms comply with the court’s order, a substantial number of the underreported shares will be able to participate in the Annual Meeting.

SAN DIEGO, Feb. 18, 2023 (GLOBE NEWSWIRE) -- Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) today posted an IRS Form 8937 (the “Form 8937”) to supplement its previously issued “Frequently Asked Questions” document under the “Investors” section of its website at www.sorrentotherapeutics.com regarding its recent dividend to Sorrento stockholders of shares of common stock of Scilex Holding Company (“Scilex”) previously held by Sorrento. The Form 8937 has been filed with the Internal Revenue Service and Sorrento expects to send copies of the form in the coming days to brokerage firms, banks, dealers and similar organizations to whom a dividend confirmation had previously been distributed by Scilex’s transfer agent, Continental Stock Transfer & Trust Company. After the close of trading on the Nasdaq Capital Market on January 19, 2023, Sorrento issued a distribution of an aggregate of 76,000,000 shares of Scilex common stock to the record holders of Sorrento common stock. Sorrento issued the distribution on a pro rata basis among its stockholders in accordance with each stockholder’s ownership percentage of Sorrento common stock as of the record date. The distribution ratio was 0.1410127 of a share of Scilex common stock for each one share of Sorrento common stock. Fractional shares issued as part of the stock distribution have been paid in cash in lieu of distributing fractional shares. At the time of the filing of the Form 8937, Sorrento estimated that its current and accumulated earnings and profits would be insufficient to characterize the distribution as a dividend. Therefore, the estimate would provide that the distribution of the Scilex common stock would be characterized as non-dividend return of capital. Sorrento stockholders are urged to consult their own tax advisor as to the particular tax consequences of the distribution of the Scilex common stock, including potential tax consequences under state, local and non-U.S. tax laws. Sorrento is providing the details on the Form 8937 for informational purposes only and not to be considered or construed as legal or tax advice. The Form 8937 is available here.
