This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K, filed with the Securities and Exchange Commission on November 7, 2024 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

The Prospectus and this prospectus supplement relate to the resale from time to time by the selling stockholders named in the Prospectus (including their permitted transferees, donees, pledgees and other successors-in-interest) (collectively, the “Selling Stockholders”) of up to an aggregate of 13,474,683 shares (the “Resale Shares”) of our common stock, par value $0.0001 per share (“Common Stock”), consisting of:

(i) up to 474,683 shares of Common Stock (the “HB Shares”), of which 161,392 shares of Common Stock are held by Cove Lane Onshore Fund, LLC (“Cove Lane”) and 313,291 shares of Common Stock are held by HBC Investments LLC (“HBC”), in each case issued on September 25, 2023, pursuant to the Settlement Agreement (as defined and described below); and

(“Oramed”) pursuant to the Scilex Oramed SPA (as defined and described below).

On September 21, 2023, we entered into, and consummated the transactions contemplated by that certain Securities Purchase Agreement, dated as of such date, between us and Oramed (the “Scilex-Oramed SPA”). Pursuant to the Scilex-Oramed SPA, among other things, on September 21, 2023, we (i) issued to Oramed (A) a senior secured promissory note due 18 months from the date of issuance in the principal amount of $101,875,000 (the “Oramed Note”), (B) a warrant to purchase up to an aggregate of 4,500,000 shares of Common Stock (the “Closing Penny Warrant”), with an exercise price of $0.01 per share and restrictions on exercisability (as more fully described elsewhere in the Prospectus), and (C) warrants to purchase up to an aggregate of 8,500,000 shares of Common Stock (the “Subsequent Penny Warrants” and together with the Closing Penny Warrant, the “Penny Warrants”), each with an exercise price of $0.01 per share and each with restrictions on exercisability (as more fully described elsewhere in the Prospectus), and (ii) caused certain outstanding warrants to purchase up to an aggregate of 4,000,000 shares of Common Stock, with an exercise price of $11.50 per share, that we acquired from Sorrento pursuant to the Sorrento SPA (as defined and described elsewhere in the Prospectus) to be transferred to Oramed, which warrants were subsequently repurchased by us from Oramed. See the section in the Prospectus titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments—Transactions with Oramed Pharmaceuticals Inc. and Sorrento Therapeutics, Inc.” for additional information regarding the Scilex-Oramed SPA and transactions related thereto.

On September 15, 2023, we entered into that certain Settlement Agreement (the “Settlement Agreement”) with Cove Lane, HBC and Hudson Bay Capital Management LP (“Hudson Bay” and collectively with Cove Lane and HBC, the “Hudson Bay Parties” and each a “Hudson Bay Party”) in connection with a previously contemplated financing with the Hudson Bay Parties. The HB Shares were issued to Cove Lane and HBC pursuant to the Settlement Agreement.

Securities registered pursuant to Section 12(b) of the Act

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

On November 1, 2024, Scilex Holding Company (the “Company”) received a letter (the “Notice”) from The Nasdaq Stock Market (“Nasdaq”) notifying the Company that, because the closing bid price for its common stock has been below $1.00 per share for 30 consecutive business days, it no longer complies with the minimum bid price requirement for continued listing on The Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”), and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the Minimum Bid Price Requirement exists if the deficiency continues for a period of 30 consecutive business days.

The Notice has no immediate effect on the listing of the Company’s common stock on The Nasdaq Capital Market. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial compliance period of 180 calendar days, or until April 30, 2025, to regain compliance with the Minimum Bid Price Requirement. During the compliance period, the Company’s shares of common stock will continue to be listed and traded on The Nasdaq Capital Market. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of ten consecutive business days during the 180 calendar day grace period.

In the event the Company is not in compliance with the Minimum Bid Price Requirement by April 30, 2025, the Company may be afforded a second 180 calendar day grace period. To qualify, the Company would be required to meet the continued listing requirements for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement. In addition, the Company would be required to provide written notice of its intention to cure the minimum bid price deficiency during this second 180-day compliance period by effecting a reverse stock split, if necessary.

The Company intends to actively monitor the bid price for its common stock between now and April 30, 2025 and will consider available options to regain compliance with the Minimum Bid Price Requirement. There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price Requirement or that the Company will otherwise be in compliance with the other listing standards for The Nasdaq Capital Market.

Forward-Looking Statements

Except for the factual statements made herein, information contained in this Current Report on Form 8-K consists of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks, uncertainties and assumptions that are difficult to predict. Words and expressions reflecting optimism, satisfaction or disappointment with current prospects or future events, as well as words such as “believes,” “intends,” “expects,” “plans” and similar expressions, or the use of future tense, identify forward-looking statements, but their absence does not mean that a statement is not forward-looking. Such forward-looking statements are not guarantees of performance and actual actions or events could differ materially from those contained in such statements. For example, there can be no assurance that the Company will meet the Minimum Bid Price Requirement during any compliance period or otherwise in the future, otherwise meet Nasdaq compliance standards, or that Nasdaq will grant the Company any relief from delisting as necessary or whether the Company can agree to or ultimately meet applicable Nasdaq requirements for any such relief. Reference is also made to other factors detailed from time to time in the Company’s periodic reports filed with the Securities and Exchange Commission, including the Company’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q. The forward-looking statements contained in this Current Report on Form 8-K speak only as of the date of this Current Report on Form 8-K and the Company assumes no obligation to publicly update any forward-looking statements to reflect changes in information, events or circumstances after the date of this Current Report on Form 8-K, unless required by law.
