Scilex Holding Company sets November 7, 2024 as the Record Date for a Dividend of Preferred Stock Exchangeable for up to 10% of Scilex’s Ownership Interest in Semnur Pharmaceuticals, Inc., its Wholly Owned Subsidiary

Scilex Holding Company (Nasdaq: SCLX, “Scilex” or “Company”), an innovative revenue-generating company focused on acquiring, developing and commercializing non-opioid pain management products for the treatment of acute and chronic pain, today announced that it has set a record date of November 7, 2024 (the “Record Date”) for the dividend of Scilex preferred stock (the “Dividend”) to its stockholders and certain other securityholders of Scilex. Subject to the Board’s right to change the Record Date and conditioned upon the effectiveness of the filing of the Certificate of Designation with the Secretary of State of the State of Delaware, the payment date (the “Payment Date”) will be determined by subsequent resolutions of the Board, which will be within 60 days following the Record Date.

The Dividend consists of an aggregate of 5,000,000 shares (the “Dividend Stock”) of Series 1 Mandatory Exchangeable Preferred Stock, par value $0.0001 per share, of Scilex (the “Series 1 Preferred Stock”), which will be automatically exchanged for a pro-rata portion of the lesser of (i) 10% of Scilex’s ownership in Semnur immediately prior to the effective time of the Business Combination and (ii) $200,000,000 divided by the closing price of Semnur common stock on any national securities exchange on which such stock is listed on the date that is 10 trading days prior to the determination date (i.e., the earlier of (a) the effective time of the Business Combination and (b) the time at which the applicable registration statement is declared effective by the SEC), in each case as set forth in the Certificate of Designation governing the Series 1 Preferred Stock.

The Dividend Stock will be subject to certain transfer restrictions set forth in the Certificate of Designation of Preferences, Rights and Limitations of Series 1 Mandatory Exchangeable Preferred Stock. The Record Date may be changed by the Board for any reason at any time prior to the actual payment of the Dividend, and payment of the Dividend is conditioned upon the Board not having revoked the dividend prior to the Payment Date, including for a material change to the solvency or surplus analysis presented to the Board. Scilex expects that the Dividend Stock will be freely tradable upon exchange for shares of post-closing public company Semnur common stock following the closing of the Business Combination.
