Scilex Holding Company Announces Financing of up to $25 Million to Enhance Commercialization of Three FDA Approved Non-Opioid Pain Management Products

• Proceeds from the financing commitment will be used to enhance the launch and commercialization of Scilex’s three FDA-approved non-opioid pain management products (ZTlido^®, Gloperba^® and Elyxyb™) for the treatment of acute and chronic pain.
• The financing will enable further investment in Scilex’s non-opioid pain management portfolio, accelerating its mission to launch innovative non-opioid pain management products in major markets.

PALO ALTO, Calif., March 21, 2023 (GLOBE NEWSWIRE) — Scilex Holding Company (Nasdaq: SCLX, “Scilex”), a majority-owned subsidiary of Sorrento Therapeutics, Inc. (OTC: SRNEQ), an innovative revenue-generating company focused on acquiring, developing and commercializing non-opioid pain management products for the treatment of acute and chronic pain, announced that it has entered into a securities purchase agreement with YA II PN, Ltd., a Cayman Islands exempt limited partnership managed by Yorkville Advisors Global, LP (”Yorkville”), for the issuance and sale of unsecured convertible debentures in the principal amount of up to $25 million.

The convertible debentures will be issued and sold in three tranches as follows: (i) $10.0 million upon the signing of the definitive agreement with respect to the debentures (the “First Closing Date”), (ii) $7.5 million upon the filing of a registration statement with the U.S. Securities and Exchange Commission (“SEC”) relating to the shares of common stock underlying the convertible debentures, and (iii) $7.5 million at the time such registration statement is declared effective by the SEC.

The convertible debentures will bear interest at a rate of 7.00% per year and will mature on December 21, 2023, the date that is nine months following the First Closing Date.

Subject to the terms and conditions of the convertible debentures, Yorkville has the right to convert all or any portion of the convertible debentures at its option into shares of Scilex’s common stock at a price of $8.00 per share (the “Conversion Price”). The Conversion Price is subject to a one-time reset equal to the average of the daily VWAP for the three consecutive trading days immediately prior to the date that is 60 days after the First Closing Date, if such average is less than the Conversion Price in effect as of such date.

Scilex intends to use the proceeds to enhance the commercialization of Scilex’s three non-opioid pain management products for the treatment of acute and chronic pain. Scilex’s suite of FDA-approved non-opioid pain management products include:

• ZTlido^®, a lidocaine topical system approved for the relief of neuropathic pain associated with post-herpetic neuralgia. ZTlido^® was strategically designed to address the limitations of current prescription lidocaine patches by providing significantly improved adhesion and continuous pain relief throughout the 12-hour administration period.
• Gloperba^®, an FDA-approved, novel, oral solution of a widely used anti-gout agent (colchicine) for the prophylaxis of gout flares in adults. No other liquid formulation is currently approved by the FDA for the treatment of gout.

• ELYXYB™, a first-line treatment and the only FDA-approved, ready-to-use oral solution for the acute treatment of migraine, with or without aura, in adults.¹ There is strong evidence for use of NSAIDs as a first-line treatment for migraine, and ELYXYB™ (celecoxib) is in the same class of agents, is fast acting and has the potential to have the lowest GI side effects of all NSAIDs.²  ELYXYB™ has the potential to further expand Scilex’s non-opioid portfolio in broader acute pain indications.

“We are pleased to conclude this agreement with Yorkville, which will provide funding to expand ZTlido^® promotion worldwide and enhance the launch and commercialization of Gloperba^® and ELYXYB™. We believe the acute and chronic pain patients are not well served with the current options on the market. A recent report from the Centers for Disease Control and Prevention states that opioids do not provide clinically meaningful pain relief and are not first line therapy for acute and chronic pain³,” said Jaisim Shah, Chief Executive Officer and President of Scilex.

The convertible debentures and the common stock issuable upon conversion thereof have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”) or any state securities law. Accordingly, the securities may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and applicable state laws. Scilex has granted Yorkville registration rights requiring Scilex to register the resale of the shares of the underlying common stock.
