If anyone provides you with different or inconsistent information, you should not rely on it. This prospectus, any accompanying prospectus supplement and any related free writing prospectus do not constitute an offer to sell or a solicitation of an offer to buy any securities other than the registered securities to which they relate, and this prospectus and any accompanying prospectus supplement do not constitute an offer to sell or the solicitation of an offer to buy securities in any jurisdiction where, or to any person to whom, it is unlawful to make such an offer or solicitation. You should not assume that the information contained in this prospectus, any accompanying prospectus supplement and any related free writing prospectus is correct on any date after the respective dates of the prospectus, such prospectus supplement or supplements and free writing prospectus, as applicable, even though this prospectus, such prospectus supplement or supplements and free writing prospectus are delivered or securities are sold pursuant thereto, as applicable, at a later date. Since the respective dates of the prospectus contained in this registration statement, any accompanying prospectus supplement and any free writing prospectus, our business, financial condition, results of operations and prospects may have changed since those dates. This prospectus contains summaries of certain provisions contained in some of the documents described herein, but reference is made to the actual documents for complete information.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before you make a decision to buy our securities, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements”, you should carefully consider the risks and uncertainties described under the section titled “Risk Factors” contained in our most recent Annual Report on Form 10-K, together with all of the other information appearing in or incorporated by reference into this prospectus, as updated by our subsequent filings with the SEC, as well as the risk factors and other information contained in any applicable prospectus supplement and any applicable free writing prospectus before deciding to invest in our securities. If any of these risks actually occurs, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus, any prospectus supplement, any post-effective amendment or in any filing or document incorporated by reference herein or therein are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

6

USE OF PROCEEDS

Except as otherwise provided in the applicable prospectus supplement or in any free writing prospectuses we have authorized for use in connection with a specific offering, we currently intend to use the net proceeds from the sale of the securities offered by this prospectus, if any, for working capital and general corporate purposes, which may include capital expenditures, commercialization expenditures, research and development expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock.

The intended application of proceeds from the sale of any particular offering of securities using this prospectus will be described in the accompanying prospectus supplement relating to such offering. The precise amount and timing of the application of these proceeds will depend upon a number of factors, such as the costs and timing of commercial and development activities, including, for example, conducting preclinical studies and clinical trials, our funding requirements and the availability and costs of other funds. Pending application of the net proceeds as described above, we intend to temporarily invest the proceeds in interest-bearing instruments.

We may bear all other costs, fees and expenses incurred in effecting the registration of the shares covered by this prospectus, including, without limitation, all registration and filing fees, Nasdaq Capital Market listing fees, and fees and expenses of our counsel and our accountants.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the documents incorporated by reference into this prospectus may contain forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act, about us and our subsidiaries. These forward-looking statements are intended to be covered by the safe harbor for forward-looking statements provided by the Private Securities Litigation Reform Act of 1995. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. These forward-looking statements rely on a number of assumptions concerning future events and include statements relating to:

Any forward-looking statements should be considered in light of these factors. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “contemplate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “will,” “would” and other similar words and expressions (including the negative of any of the foregoing), but the absence of these

8

words does not mean that a statement is not forward-looking. These forward-looking statements are based on information available as of the date of this prospectus and our management’s current expectations, forecasts and assumptions, and involve a number of judgments, known and unknown risks and uncertainties and other factors, many of which are outside the control of the Company and our directors, officers and affiliates. There can be no assurance that future developments will be those that have been anticipated. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date. You are cautioned not to put undue reliance on any forward-looking statements. Except as otherwise required by law, we do not assume any obligation to update any forward-looking statements.

You should read this prospectus, or any accompanying prospectus supplement and the documents incorporated by reference completely and with the understanding that our actual future results may be materially different from what we currently expect. Our business and operations are and will be subject to a variety of risks, uncertainties and other factors. Consequently, actual results and experience may materially differ from those contained in any forward-looking statements. Such risks, uncertainties and other factors that could cause actual results and experience to differ from those projected include, but are not limited to, the risk factors set forth in Part I —Item 1A, “Risk Factors”, in our Annual Report on Form 10-K for the year ended December 31, 2022 and Part II—Item 1A, “Risk Factors”, in our Quarterly Reports on Form 10-Q for the quarters ended March  31, 2023, June  30, 2023 and September 30, 2023 and in other filings with the SEC, which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future, that are incorporated by reference in this prospectus.

You should assume that the information appearing in this prospectus, any accompanying prospectus supplement, any related free writing prospectus and any document incorporated herein by reference is accurate as of its date only. Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf, you should not place undue reliance on any forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made. New factors emerge from time to time, and it is not possible for us to predict which factors will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Some of these risks and uncertainties may in the future be amplified by COVID-19 (or other similar disruptions), and there may be additional risks that we consider immaterial or which are unknown. It is not possible to predict or identify all such risks. All written or oral forward-looking statements attributable to us or any person acting on our behalf made after the date of this prospectus are expressly qualified in their entirety by the risk factors and cautionary statements contained in and incorporated by reference into this prospectus. Unless legally required, we do not undertake any obligation to release publicly any revisions to such forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events.

DESCRIPTION OF CAPITAL STOCK

General Matters

The Restated Certificate of Incorporation of the Company (the “Certificate of Incorporation”) authorizes the issuance of (i) 740,000,000 shares of Common Stock and (ii) 45,000,000 shares of preferred stock, $0.0001 par value per share (the “Preferred Stock”), of which 29,057,097 shares have been designated as Series A Preferred Stock. As of November 30, 2023, there were 157,905,655 shares of Common Stock and 29,057,097 shares of Series A Preferred Stock issued and outstanding.

Our Common Stock

The Certificate of Incorporation provides the following with respect to the rights, powers, preferences and privileges of our Common Stock.

Dividend Rights

The holders of our Common Stock are entitled to receive ratably those dividends, if any, that may be declared from time to time by our board of directors (the “Board”) upon the shares of our capital stock, which dividends may be paid either in cash, in property or in shares of our capital stock, subject to preferences that may be applicable to preferred stock, if any, then outstanding. Subject to applicable law and the Certificate of Incorporation, our Board will have full power to determine whether any dividends shall be declared and paid to stockholders.

Voting Rights

Each holder of our Common Stock will be entitled to one vote for each share of our Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote, except for any amendment to the Certificate of Incorporation that relates solely to the terms of one or more outstanding classes or series of our Preferred Stock if the holders of such affected classes or series are entitled, either separately or together with the holders of one or more other such classes or series, to vote thereon pursuant to the Certificate of Incorporation or the Delaware General Corporation Law, as amended (the “DGCL”). Any action or matter presented to the stockholders at a duly called or convened meeting, at which a quorum is present, will be decided by the affirmative vote of the holders of a majority of the votes cast affirmatively or negatively (excluding abstentions) at the meeting by the holders entitled to vote thereon, except that our directors will be elected by a plurality of the votes cast.

Right to Receive Liquidation Distributions

In the event of a liquidation, dissolution or winding up of the Company, the holders of our Common Stock will be entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of our Preferred Stock, if any, then outstanding.

No Preemptive or Similar Rights

Our Common Stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our Common Stock.

Fully Paid and Non-Assessable

The outstanding Vickers Ordinary Shares and the shares of our Common Stock issued in the Business Combination are fully paid and non-assessable. The “Vickers Ordinary Shares” consist of (i) the ordinary shares, par value $0.0001 per share, of Vickers prior to the Domestication and (ii) the Common Stock following the Domestication.

10

Our Preferred Stock

The Certificate of Incorporation authorizes our Board, subject to limitations prescribed by Delaware law, to issue up to 45,000,000 shares of preferred stock in one or more series, to determine and fix from time to time the number of shares to be included in each such series and to fix the designations, powers, rights and preferences of the shares of each such series, and the qualifications, limitations and restrictions thereof, including voting rights (if any), dividend rights, dissolution rights, conversion rights, exchange rights and redemption rights, in each case without further vote or action by our stockholders. The number of authorized shares of our Common Stock and our Preferred Stock may be increased or decreased (but not below the number of the shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of our outstanding stock entitled to vote thereon.

Our Board may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our Common Stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control and may adversely affect the market price of our Common Stock and the voting and other rights of the holders of our Common Stock. Other than the Series A Preferred Stock issued to Sorrento Therapeutics, Inc. (“Sorrento”) in connection with the closing of the Business Combination, there are no other Preferred Stock outstanding and we have no current plans to issue any other shares of preferred stock.

Number and Designation

We filed the Certificate of Designations of the Company, designating 29,057,097 shares of our preferred stock as “Series A Preferred Stock” (“Certificate of Designations”). As of the date of this prospectus, 29,057,097 shares of the Series A Preferred Stock are held by SCLX Stock Acquisition JV LLC, our indirect wholly-owned subsidiary, which shares were repurchased from Sorrento pursuant to the terms of the Stock Purchase Agreement, dated September 21, 2023, entered into between us and Sorrento (the “Sorrento SPA”) and represent all of the shares of Series A Preferred Stock that were previously owned by Sorrento. The shares of Series A Preferred Stock have all of the rights, preferences and privileges set forth in the Certificate of Designations as more fully described below.

Rank

The Series A Preferred Stock shall rank (i) senior to all of our Common Stock, and to all other classes or series of our capital stock, except for any such other class or series, the terms of which expressly provide that it ranks on parity with the Series A Preferred Stock as to dividend rights and rights on liquidation, dissolution or winding-up of the Company (“Junior Securities”); and (ii) on parity with each class or series of our capital stock, created specifically ranking by its terms on parity with the Series A Preferred Stock as to dividend rights and rights on liquidation, dissolution or winding-up of the Company (“Parity Securities”).

Dividend Rights

Holders of the Series A Preferred Stock shall not be entitled to dividends unless we pay dividends to holders of the Common Stock and shall be entitled to receive, when, as and if declared by our Board, such dividends (whether in cash or other property) as are paid to holders of our Common Stock to the same extent as if such holders of Series A Preferred Stock had been deemed to convert their shares of Series A Preferred Stock into Common Stock and had held such shares of Common Stock on the record date for such dividends and distributions. Such payments will be made concurrently with the dividend or distribution to the holders of the Common Stock.

Liquidation Preference

In the event of a change of control, liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, before any payment or distribution of our property or assets (whether capital or surplus) shall be made to or set apart for the holders of Junior Securities, the holders of Series A Preferred Stock shall be

11

entitled to receive an amount per share of Series A Preferred Stock equal to the greater of (i) the sum of $10.00 (which amount shall be appropriately adjusted in the event of any stock split, stock combination or other similar recapitalization of the Series A Preferred Stock) and all accrued and unpaid dividends and (ii) the amount such share of Series A Preferred Stock would be entitled to receive pursuant to the change of control, liquidation, dissolution or winding-up of the Company assuming that such share had been converted into shares of Common Stock in a Deemed Conversion (as defined below).

Conversion and Redemption Rights

The shares of Series A Preferred Stock will not be convertible into Common Stock or any of our other securities and will not be redeemable by the Company; provided, however, a number of the rights, preferences and privileges of the Series A Preferred Stock set forth in the Certificate of Designations will be determined based on an as-converted-to-Common Stock basis or otherwise assume that the shares of Series A Preferred Stock are converted into shares of Common Stock. Accordingly, the number of shares of Common Stock that each share of Series A Preferred Stock is deemed to be (or otherwise being treated as) converted into for the purpose of affecting the various rights, preferences and privileges of the Series A Preferred Stock set forth in the Certificate of Designation (a “Deemed Conversion”), whether in connection with a change of control or otherwise, shall be equal to the result obtained by dividing (i) stated value by (ii) $10.00 (subject to anti-dilution adjustments).

Voting and Other Preferred Rights

Except as otherwise required by law or as set forth in the Certificate of Designations, the holders of shares of Series A Preferred Stock will be entitled to vote, together with the holders of shares of Common Stock and not separately as a class, on all matters upon which holders of shares of Common Stock have the right to vote. The holders of shares of Series A Preferred Stock will be entitled to one vote for each share of Common Stock that such share of Series A Preferred Stock would otherwise be convertible into pursuant to a Deemed Conversion on the record date for the determination of the stockholders entitled to vote.

As long as any shares of Series A Preferred Stock are outstanding, we shall not, without the affirmative vote of the holders of at least a majority of the outstanding shares of Series A Preferred Stock (a) change the Series A Preferred Stock (whether by merger, consolidation, reclassification or otherwise) into cash, securities or other property except in accordance with the terms of the Certificate of Designations; (b) create, authorize or issue any Parity Security or other equity security the terms of which provide that it ranks senior to the Series A Preferred Stock with respect to dividend rights or rights upon liquidation, dissolution or winding-up of the Company, or increase the authorized amount of any such other class or series; or (c) amend the Certificate of Incorporation or the Certificate of Designations in any manner that adversely affects the holders of Series A Preferred Stock.

Registration Rights

Pursuant to the Registration Rights Agreement entered into in connection with the closing of the Business Combination, certain of our stockholders are able to demand that we register their registrable securities under certain circumstances and each also have piggyback registration rights for these securities. In addition, we are required to file and maintain an effective registration statement under the Securities Act covering the resale of all such registrable securities. We have filed a registration statement on Form S-1 (File No. 333-268603) which was initially declared effective by the SEC on December 27, 2022, in order to satisfy these obligations. The registration of these securities will enable the public sale of such securities. The presence of these additional shares of Common Stock trading in the public market may have an adverse effect on the market price of our securities.

Anti-Takeover Matters in our Governing Documents and Under Delaware Law

Certain provisions of Delaware law, along with the Certificate of Incorporation and the Bylaws of Company (the “Bylaws”), all of which are summarized below, may have the effect of delaying, deferring or discouraging another person from acquiring control of the Company. These provisions are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed, in part, to encourage persons seeking to acquire control of the Company to first negotiate with our Board. However, these provisions could have the effect of delaying, discouraging or preventing attempts to acquire the Company, which could deprive our stockholders of opportunities to sell their shares of our Common Stock at prices higher than prevailing market prices.

Authorized but Unissued Capital Stock

The authorized but unissued shares of our Common Stock and our Preferred Stock are available for future issuance without stockholder approval, subject to any limitations imposed by the rules and listing standards of The Nasdaq Stock Market LLC. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved Common Stock and Preferred Stock could make more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Impact of the Equity Repurchase Transaction on Provisions Related to a Sorrento Trigger Event

Certain provisions of our Certificate of Incorporation related to the number of authorized directors, filling vacancies on the Board, removal of directors, stockholder actions by written consent, calling of special meetings of our stockholders, our election to not be governed by Section 203 of the DGCL and amendments to our Certificate of Incorporation and our Bylaws lapse upon or are triggered at the time Sorrento Therapeutics, Inc. (“Sorrento”, together with its affiliates, subsidiaries, successors and assigns (other than us and our subsidiaries)) first ceases to beneficially own more than 50% in voting power of the then-outstanding shares of our capital stock entitled to vote generally in the election of directors (the “Sorrento Trigger Event”). Upon the closing of the equity repurchase transaction pursuant to the Sorrento SPA, a Sorrento Trigger Event occurred. The disclosures below related to the foregoing provisions are based on the occurrence of such event.

Classified Board of Directors

The Certificate of Incorporation provides that our Board are divided into three classes, with the classes as nearly equal in number as practical and each class serving three-year staggered terms. The directors in each class serve for a three-year term (except that the term of our current Class II directors shall expire at the second annual meeting of stockholders following the closing of the Business Combination), with one class being elected each year by the stockholders. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of the Company, because it generally makes it more difficult for stockholders to replace a majority of the directors.

The Certificate of Incorporation also provides that the total number of directors shall be determined from time to time exclusively by our Board.

Removal of Directors; Vacancies

The Certificate of Incorporation provides that, except as otherwise required by law or the Certificate of Incorporation, directors may be removed only for cause and only by the affirmative vote of the holders of at least 66 2/3% in voting power of all the then-outstanding shares of our capital stock entitled to vote thereon, voting together as a single class, in each case subject to the rights of holders of any series of Preferred Stock.

13

In addition, the Certificate of Incorporation provides that, except as otherwise provided therein or by law, any vacancy resulting from the death, resignation, removal or disqualification of a director or other cause, or any newly created directorship in our Board, shall be filled only by a majority of the directors then in office, although less than a quorum, and shall not be filled by our stockholders, in each case subject to the rights of the holders of any series of Preferred Stock.

These provisions may have the effect of deferring, delaying, or discouraging hostile takeovers, changes in control of the Company or changes in our management.

Delaware Anti-Takeover Law

The Certificate of Incorporation provides that we are governed by Section 203 of the DGCL.

Section 203 of the DGCL prohibits persons deemed to be “interested stockholders” from engaging in a “business combination” with a publicly held Delaware corporation for three years following the date such persons become interested stockholders, unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions that are not approved in advance by our Board, including discouraging attempts that might result in a premium over the market price for the shares of Common Stock held by stockholders.

The Certificate of Incorporation provides that the restrictions on business combination of Section 203 of the DGCL will not apply to Sorrento or its current or future Affiliates (as defined in the Certificate of Incorporation) regardless of the percentage of ownership of the total voting power of all the then-outstanding shares of our capital stock entitled to vote generally in the election of directors beneficially owned by them.

No Cumulative Voting

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation specifically authorizes cumulative voting. The Certificate of Incorporation does not authorize cumulative voting. Therefore, stockholders holding a majority of the shares of our capital stock entitled to vote generally in the election of directors will be able to elect all of our directors.

Special Stockholder Meetings

The Certificate of Incorporation provides that special meetings of stockholders may only be called by order of the Chairperson of our Board, our Board or the Chief Executive Officer, subject to the rights of the holders of any series of Preferred Stock with respect to such series of preferred stock. The Bylaws prohibits the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying, or discouraging hostile takeovers or changes in control or management.

Director Nominations and Stockholder Proposals

The Bylaws establishes advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our Board or a committee of our Board. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information.

14

Generally, to be timely, a stockholder’s notice must be delivered to our secretary at our principal executive offices not earlier than the close of business on the 120th day nor later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting (in the case of the first annual meeting of stockholders held after January 1, 2023, the date of the preceding year’s annual meeting of the stockholders shall be deemed to be June 30, 2022); provided, however, that, if the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 60 days after the anniversary of the preceding year’s annual meeting, or if no annual meeting was held in the preceding year, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting and the 10th day following the day on which public announcement of the date of such meeting is first made by us. The Bylaws also specifies requirements as to the form and content of a stockholder’s notice. The Bylaws allows any previously scheduled stockholders meeting to be postponed, adjourned or canceled by resolution of our Board; provided, however, that with respect to any special meeting of stockholders scheduled at the request of Sorrento, our Board is not allowed to postpone, reschedule or cancel without the prior written consent of Sorrento. In addition, the Bylaws allows the chair of a meeting of the stockholders to adopt rules and regulations for the conduct of that meeting that may have the effect of precluding the conduct of certain business at that meeting if the rules and regulations are not followed. These provisions may also defer, delay, or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control.

Stockholder Action by Written Consent

Pursuant to Section 228 of the DGCL and the terms of the Certificate of Incorporation, any action required or permitted to be taken by our stockholders must be effected by a duly called annual or special meeting of such stockholders, subject to the rights of the holders of any series of Preferred Stock with respect to such series of preferred stock.

Amendment of Certificate of Incorporation or Bylaws

The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage.

The Certificate of Incorporation provides that the affirmative vote of the holders of at least 66 2/3% of the voting power of the then-outstanding shares of our capital stock entitled to vote thereon, voting together as a single class, will be required to alter, amend or repeal the following provisions of the Certificate of Incorporation: Article V (Board of Directors), Article VI (Consent of Stockholders in Lieu of Meeting; Special Meetings of Stockholders), Article VII (Limitation of Liability), Article VIII (Corporate Opportunities and Competition), Article IX (Exclusive Forum), Article X (Section 203 of the DGCL) and Article XI (Amendment of Certificate of Incorporation and Bylaws), and no other provision may be adopted, amended or repealed that would have the effect of modifying or permitting the circumvention of the provisions set forth in any of such Articles.

The Certificate of Incorporation and the Bylaws provide that, our Board is authorized to make, alter and repeal the Bylaws, without the consent or vote of the stockholders, by an approval of a majority of the total authorized number of directors. The affirmative vote of the holders of at least 66 2/3% of the voting power of the then-outstanding shares of our capital stock entitled to vote thereon, voting together as a single class, will be required to alter, amend or repeal the Bylaws.

The provisions of the DGCL, the Certificate of Incorporation and the Bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our Common Stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the composition of our Board and

15

our management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Exclusive Forum

The Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) and any appellate court therefrom shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, employees or stockholders to us or our stockholders, (iii) any action asserting a claim against us or any of our current or former directors, officers, employees or stockholders arising pursuant to any provision of the DGCL or of the Certificate of Incorporation or the Bylaws, (iv) any claim or cause of action seeking to interpret, apply, enforce or determine the validity of the Certificate of Incorporation or the Bylaws, (v) any action or proceeding asserting a claim against us or any of our current or former directors, officers, employees or stockholders as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware, or (vi) any action asserting an “internal corporate claim,” as that term is defined in Section 115 of the DGCL. The foregoing exclusive forum provisions will not apply to claims arising under the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.

In addition, the Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

Although we believe these provisions benefit us by providing increased consistency in the application of applicable law in the types of lawsuits to which they apply, the provisions may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings and there is uncertainty as to whether a court would enforce such provisions. In addition, investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. It is possible that, in connection with any applicable action brought against us, a court could find the choice of forum provisions contained in the Certificate of Incorporation to be inapplicable or unenforceable in such action. We may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in the Certificate of Incorporation.

Limitation of Liability and Indemnification of Directors and Officers

The Certificate of Incorporation and the Bylaws contain provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by the DGCL. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:

16

The Certificate of Incorporation also provides that if the DGCL is amended to permit further elimination or limitation of the personal liability of directors, then the liability of our directors will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

The Bylaws provide that we shall indemnify any person who is or was a director or officer of the Company or who is or was serving at our request as a director, officer or trustee of another corporation, limited liability company, partnership, joint venture, employee benefit plan, trust, nonprofit entity or other enterprise (a “Covered Person”) and who is or was a party to, is threatened to be made a party to, or is otherwise involved (including as a witness) in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, or investigative based on such person’s actions in his or her official capacity as a director or officer of the Company or as a director, officer or trustee of another corporation, limited liability company, partnership, joint venture, employee benefit plan, trust, nonprofit entity or other enterprise (to the extent serving in such position at our request), in each case against all liability and loss suffered (including, without limitation, any judgments, fines, excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974 and amounts paid in settlement consented to in writing by us) and expenses (including attorneys’ fees), actually and reasonably incurred by such person in connection therewith, subject to certain conditions. In addition, the Bylaws provide that we may, to the fullest extent permitted by law, (i) advance costs, fees or expenses (including attorneys’ fees) incurred by a Covered Person defending or participating in any proceeding in advance of the final disposition of such proceeding, subject to certain exceptions, and (ii) purchase and maintain insurance, at our expense, to protect us and any person who is or was a director, officer, employee or agent of the Company or is or was a director, officer, employee or agent of the Company serving at our request as a director, officer, employee or agent of another corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise against any liability, expense or loss, whether or not we would have the power or obligation to indemnify such person against such liability, expense or loss under the DGCL or the provisions of the Bylaws.

We have entered into indemnification agreements with each of our directors, executive officers and certain other employees as determined by our Board. These agreements, among other things, require us to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require us to advance all expenses actually and reasonably incurred by the directors and executive officers in connection with any proceeding. Our Board believes that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

The above description of the indemnification provisions of the Certificate of Incorporation, the Bylaws and the indemnification agreements is not complete and is qualified in its entirety by reference to these documents, each of which is filed as an exhibit to the registration statement of which this prospectus is a part.

Certain of our non-employee directors may, through their relationships with their employers, be insured or indemnified against certain liabilities incurred in their capacity as members of our Board.

The limitation of liability and indemnification provisions in the Certificate of Incorporation and the Bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and our stockholders. In addition, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors or executive officers, we have been informed that in the opinion of the SEC, such indemnification is against public policy and is therefore unenforceable.

Conflicts of Interest

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. The Certificate of

17

Incorporation provides that, to the fullest extent permitted by law, no Identified Person (as defined therein) will have any duty to refrain from (i) engaging in a corporate opportunity in the same or similar business activities or lines of business in which we or our affiliates are engaged or that are deemed to be competing with us or any of our affiliates or (ii) otherwise investing in or providing services to any person that is engaged in the same or similar business activities as we or our affiliates or competes with us or our affiliates. In addition, to the fullest extent permitted by law, no Identified Person will have any obligation to offer to us or our subsidiaries or affiliates the right to participate in any corporate opportunity in the same or similar business activities or lines of business in which we or our affiliates are engaged or that are deemed to be competing with us or any of our affiliates. Subject to the preceding sentences and to the fullest extent permitted by applicable law, neither we nor any of our subsidiaries shall have any rights in any business interests, activities or ventures of any Identified Person, and we waive and renounce any interest or expectancy therein, except with respect to opportunities offered solely and expressly to our officers in their capacity as such.

Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation of the Company. Pursuant to Section 262 of the DGCL, stockholders who properly demand and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery. However, appraisal rights are not available in all circumstances.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in the Company’s name to procure a judgment in its favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our capital stock at the time of the transaction to which the action relates.

SPAC Warrants

At the effective time of the Domestication, each warrant to purchase Vickers Ordinary Shares that was issued and outstanding immediately prior to the effective time of the Domestication and not terminated pursuant to its terms was converted into a warrant to purchase shares of our Common Stock on the same terms and conditions as are in effect with respect to such warrant immediately prior to the effective time of the Domestication. As of November 30, 2023, there are 10,958,309 outstanding SPAC Warrants.

“SPAC Warrants” consist of (i) the redeemable warrants that were included in the Units (each of which consisted of one Vickers Ordinary Share and one-half of one redeemable warrant) that entitle the holder of each whole warrant to purchase one Vickers Ordinary Share at a price of $11.50 per share (the “Public Warrants”), and (ii) the 6,840,000 warrants sold in a private placement to Vickers Venture Fund VI Pte Ltd and Vickers Venture Fund VI (Plan) Pte Ltd consummated on January 11, 2021 (of which 2,736,000 were subsequently forfeited and 3,104,000 were transferred to Sorrento, in each case in connection with the Business Combination) (the “Private Placement Warrants”).

Public Warrants

Each Public Warrant entitles the registered holder thereof to purchase one share of our Common Stock at a price of $11.50 per share, subject to adjustment as described in this prospectus. We may, in our sole discretion, lower the warrant exercise price at any time prior to the expiration date for a period of not less than 20 business days and any such reduction will be applied consistently to all of the warrants, provided that we will provide at least 20 days’ prior written notice to registered holders of the warrants.

18

However, no Public Warrants will be exercisable for cash unless we have an effective and current registration statement covering the issuance of the Common Stock issuable upon exercise of the warrants and a current prospectus relating to such Common Stock. Notwithstanding the foregoing, if a registration statement covering the issuance of the Common Stock issuable upon exercise of the Public Warrants is not effective within 90 days from the consummation of the Business Combination, warrantholders may, from the 91st day after the consummation of the Business Combination until such time as there is an effective registration statement and during any period when we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to an available exemption from registration under the Securities Act. If an exemption from registration is not available, holders will not be able to exercise their warrants on a cashless basis.

The warrants will expire five years from the consummation of the Business Combination (i.e., November 10, 2027) at 5:00 p.m., New York City time or earlier upon redemption or liquidation.

We may call the warrants for redemption (excluding the Private Placement Warrants), in whole and not in part, at a price of $0.01 per warrant:

We may not exercise such redemption right if the issuance of the Common Stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or we are unable to effect such registration or qualification. The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.

The redemption criteria for our warrants have been established at a price which is intended to provide warrantholders a reasonable premium to the initial exercise price and provide a sufficient differential between the then-prevailing per share price of our Common Stock and the warrant exercise price so that if the per share price of our Common Stock declines as a result of our redemption call, the redemption will not cause the per share price of our Common Stock to drop below the exercise price of the warrants.

If we call the warrants for redemption as described above, our management will have the option to require all holders of warrants to exercise their warrants on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the fair market value by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported closing price of the shares of our Common Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. For example, if a holder held 150 warrants to purchase 150 shares of our Common Stock and the fair market value on the trading date prior to exercise was $15.00, that holder would receive 35 shares of our Common Stock without the payment of any additional cash consideration. Whether we will exercise our option to require all holders to exercise their warrants on a “cashless basis” will depend on a variety of factors including the price of our Common Stock at the time the warrants are called for

19

redemption, our cash needs at such time and concerns regarding dilutive share issuances. Requiring a cashless exercise in this manner will reduce the number of shares of our Common Stock to be issued and thereby lessen the dilutive effect of a warrant redemption. We believe this feature is an attractive option to use if we do not need the cash from the exercise of the Public Warrants.

The warrants are issued in registered form under a warrant agreement (the “Warrant Agreement”) between Continental Stock Transfer & Trust Company, as warrant agent, and us. The Warrant Agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the registered holders of a majority of the then-outstanding warrants (including the Private Placement Warrants) in order to make any change that adversely affects the interests of the registered holders.

The exercise price and number of shares of Common Stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of (i) a stock dividend or split up, (ii) a consolidation, combination, reverse stock split or reclassification of the Common Stock, (iii) extraordinary dividend or (iv) reclassification or reorganization of the outstanding Common Stock or an merger or consolidation of us with or into another corporation. However, the warrants will not be adjusted for issuances of shares of Common Stock at a price below the par value per share issuable upon exercise of the warrants. Whenever the number of shares of Common Stock purchasable upon the exercise of the warrants is adjusted, the warrant exercise price will be adjusted by multiplying such warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of Common Stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of Common Stock so purchasable immediately thereafter.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified check or bank draft payable to the order of the warrant agent or wire transfer, for the number of warrants being exercised. The warrantholders do not have the rights or privileges of holders of shares of Common Stock and any voting rights until they exercise their warrants and receive shares of Common Stock. After the issuance of shares of Common Stock upon exercise of the warrants, each holder will be entitled to one vote for each share of Common Stock held of record on all matters to be voted on by stockholders.

Except as described above, no Public Warrants will be exercisable for cash and we will not be obligated to issue shares of Common Stock upon exercise of a warrant unless the shares of Common Stock issuable upon such warrant exercise have been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. Under the terms of the Warrant Agreement, we have agreed to use our best efforts to meet these conditions and to maintain a current prospectus relating to the Common Stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so and, if we do not maintain a current prospectus relating to the Common Stock issuable upon exercise of the warrants, holders will be unable to exercise their warrants and we will not be required to settle any such warrant exercise. If the prospectus relating to the Common Stock issuable upon the exercise of the warrants is not current or if the Common Stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, we will not be required to net cash settle or cash settle the warrant exercise, the warrants may have no value, the market for the warrants may be limited and the warrants may expire worthless.

Warrantholders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrantholder would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder (together with such holder’s affiliates) would beneficially own in excess of 9.8% of the Common Stock outstanding immediately after giving effect to such exercise.

20

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round up to the nearest whole number of shares of Common Stock to be issued to the warrantholder.

Private Placement Warrants

The Private Placement Warrants are identical to the Public Warrants except that such Private Placement Warrants are exercisable for cash (even if a registration statement covering the issuance of the Common Stock issuable upon exercise of such warrants is not effective) or on a cashless basis, at the holder’s option, and will not be redeemable by us, in each case so long as they are still held by the initial purchasers or their affiliates.

The foregoing summary of the terms and conditions of the SPAC Warrants does not purport to be complete and is qualified in its entirety by reference to the copy of the specimen warrant certificate and the Warrant Agreement that are filed as exhibits to the registration statement of which this prospectus forms a part.

Penny Warrants

In connection with the closing of the transactions contemplated by the Securities Purchase Agreement, dated September 21, 2023, between us and Oramed Pharmaceuticals Inc. (“Oramed” and such Securities Purchase Agreement, the “Scilex-Oramed SPA”), we issued warrants to purchase Common Stock, having an exercise price of $0.01 per share, subject to adjustment as provided therein (such warrants, the “Penny Warrants”), to Oramed.

The warrant to purchase up to an aggregate of 4,500,000 shares of our Common Stock, with an exercise price of $0.01 per share, which we issued to Oramed pursuant to the Scilex-Oramed SPA (the “Closing Penny Warrant”), will be exercisable upon the earliest of (i) March 14, 2025, (ii) the date on which the senior secured promissory note due 18 months from the date of issuance in the principal amount of $101, 875,000 issued by us to Oramed pursuant to the Scilex-Oramed SPA (the “Oramed Note”) has been repaid in full and (iii) the Management Sale Trigger Date (as defined therein), if any, and will expire on the date that is the fifth anniversary of the issuance date. For purposes of the Penny Warrants, the Management Sale Trigger Date is generally the first date on which either Dr. Henry Ji, our Executive Chairperson, or Mr. Jaisim Shah, our Chief Executive Officer and President and a member of the Board, engages in certain sales or other similar transfers of shares of Common Stock or other of our or any of our subsidiaries’ securities, subject to certain exceptions as are customary for lock-up agreements executed by directors and officers in connection with financings or similar transactions.

Pursuant to the Scilex-Oramed SPA, we issued to Oramed four warrants (each a “Subsequent Penny Warrant”) to purchase up to an aggregate of 8,500,000 shares of our Common Stock, each with an exercise price of $0.01 per share, each for 2,125,000 shares of Common Stock, one of which shall vest and become exercisable on the date that is the later of (i) each of March 19, 2024, June 17, 2024, September 15, 2024 or December 14, 2024 (the “Subsequent Penny Warrant Vesting Date”) and (ii) the earliest of (A) March 14, 2025, (B) the date on which the Oramed Note has been repaid in full and (C) the Management Sale Trigger Date (as defined therein), if any. Each Subsequent Penny Warrant will expire on the date that is the fifth anniversary of the issuance date; provided that, if the Oramed Note is repaid in full prior to the Subsequent Penny Warrant Vesting Date applicable to such Subsequent Penny Warrant, such Subsequent Penny Warrant will expire on the date the Oramed Note is repaid in full.

The exercise price of the Closing Penny Warrant issued to Oramed pursuant to the Scilex-Oramed SPA is $0.01 per share, subject to adjustment as provided therein. The exercise price and number of shares of Common Stock issuable upon the exercise of the Penny Warrants will be subject to adjustment in the event of any stock dividend, stock split, recapitalization, reorganization or similar transaction, as described in the Penny Warrants; provided that there shall not be any adjustment to the exercise price of the Penny Warrants in the event we combine (by combination, reverse stock split or otherwise) our Common Stock into a smaller number of shares.

21

Oramed may exercise the Penny Warrants by means of a “cashless exercise.” The Closing Penny Warrant and the Subsequent Penny Warrants utilize the same form of warrant.

The Penny Warrants may not be exercised if Oramed, together with its affiliates, would beneficially own in excess of 9.9% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise (the “Oramed Beneficial Ownership Limitation”); provided, however, that upon 61 days’ prior notice to us, Oramed may increase or decrease the Oramed Beneficial Ownership Limitation.

The foregoing summary of the terms and conditions of the Penny Warrants does not purport to be complete and is qualified in its entirety by reference to the copy of the form of Penny Warrants that is filed as an exhibit to the registration statement of which this prospectus forms a part.

Transfer Agent and Registrar

The transfer agent and registrar for our Common Stock is Continental Stock Transfer & Trust Company. The transfer agent’s address is 1 State Street, 30^th Floor, New York, New York 10004.

Listing

Shares of our Common Stock and Public Warrants are listed on the Nasdaq Capital Market under the symbols “SCLX” and “SCLXW”, respectively.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses we authorize for use in connection with a specific offering of debt securities, as well as the complete indenture that contains the terms of the debt securities.

General Matters

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations or financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities”, which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount” (“OID”), for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in the applicable prospectus supplement.

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

23

24

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our Common Stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our Common Stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions that may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) that could adversely affect holders of debt securities.

Covenants

We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities.

Subordination

Debt securities of a series may be subordinated, which we refer to as subordinated debt securities, to senior indebtedness (as defined in the applicable prospectus supplement) to the extent set forth in the prospectus supplement relating thereto. To the extent we conduct operations through subsidiaries, the holders of debt securities (whether or not subordinated debt securities) will be structurally subordinated to the creditors of our subsidiaries.

25

Consolidation, Merger or Sale

We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to, any person, which we refer to as a successor person, unless:

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us.

Events of Default under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:

No event of default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an event of default with respect to any other series of debt securities. The occurrence of certain events of default or an acceleration under the indenture may constitute an event of default under certain of our other indebtedness outstanding from time to time.

If an event of default with respect to debt securities of any series outstanding at the time occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) of, and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a

declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture. We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an event of default.

The indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture, unless the trustee receives indemnity satisfactory to it against any loss, liability or expense. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

Notwithstanding the foregoing, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any default or event of default (except in payment on any debt securities of that series) with respect to debt securities of that series if it in good faith determines that withholding notice is in the interest of the holders of those debt securities.

Modification of Indenture; Waiver

We may modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

27

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of or any interest on, any debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (except for certain obligations to register the transfer or exchange of debt securities of such series, to replace stolen, lost or mutilated debt securities of such series, and to maintain paying agencies and certain provisions relating to the treatment of funds held by paying agents). We will be so discharged upon the deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, foreign government obligations, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent certified public accountants to pay and discharge each installment of principal and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and such opinion shall confirm based thereon that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

28

The conditions include:

Covenant Defeasance and Events of Default. In the event we exercise our option to effect covenant defeasance with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amount of money and/or U.S. government obligations or foreign government obligations on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. In such a case, we would remain liable for those payments.

“Foreign Government Obligations” means, with respect to debt securities of any series that are denominated in a currency other than U.S. dollars:

Form, Exchange and Transfer

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company, as depositary, or a nominee (we will refer to any debt security represented by a global debt security as a book-entry debt security), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a certificated debt security) as set forth in the applicable prospectus supplement. Except as set forth under the heading “-Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities. The holder may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. No service charge will be made for any transfer or exchange of certificated debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

The holder may effect the transfer of certificated debt securities and the right to receive the principal of and interest on, certificated debt securities only by surrendering the certificate representing those certificated debt

29

securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Global Debt Securities and Book-Entry System. Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the depositary, and registered in the name of the depositary or a nominee of the depositary.

We will require the depositary to agree to follow the following procedures with respect to book-entry debt securities.

Ownership of beneficial interests in book-entry debt securities will be limited to persons who have accounts with the depositary for the related global debt security, which we refer to as participants, or persons who may hold interests through participants. Upon the issuance of a global debt security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the book-entry debt securities represented by such global debt security beneficially owned by such participants. The accounts to be credited will be designated by any dealers, underwriters or agents participating in the distribution of the book-entry debt securities. Ownership of book-entry debt securities will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for the related global debt security (with respect to interests of participants) and on the records of participants (with respect to interests of persons holding through participants). The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair the ability to own, transfer or pledge beneficial interests in book-entry debt securities.

So long as the depositary for a global debt security, or its nominee, is the registered owner of that global debt security, the depositary or its nominee, as the case may be, will be considered the sole owner or holder of the book-entry debt securities represented by such global debt security for all purposes under the indenture. Except as described below, beneficial owners of book-entry debt securities will not be entitled to have securities registered in their names, will not receive or be entitled to receive physical delivery of a certificate in definitive form representing securities and will not be considered the owners or holders of those securities under the indenture. Accordingly, each person beneficially owning book-entry debt securities must rely on the procedures of the depositary for the related global debt security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indenture.

We understand, however, that under existing industry practice, the depositary will authorize the persons on whose behalf it holds a global debt security to exercise certain rights of holders of debt securities, and the indenture provides that we, the trustee and our respective agents will treat as the holder of a debt security the persons specified in a written statement of the depositary with respect to that global debt security for purposes of obtaining any consents or directions required to be given by holders of the debt securities pursuant to the indenture.

We will make payments of principal of, and premium and interest on, book-entry debt securities to the depositary or its nominee, as the case may be, as the registered holder of the related global debt security. Scilex, the trustee and any other agent of ours or agent of the trustee will not have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to beneficial ownership interests.

We expect that the depositary, upon receipt of any payment of principal of, and premium or interest on, a global debt security, will immediately credit participants’ accounts with payments in amounts proportionate to the respective amounts of book-entry debt securities held by each participant as shown on the records of such depositary. We also expect that payments by participants to owners of beneficial interests in book-entry debt securities held through those participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

30

We will issue certificated debt securities in exchange for each global debt security if the depositary is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days. In addition, we may at any time and in our sole discretion determine not to have the book-entry debt securities of any series represented by one or more global debt securities and, in that event, will issue certificated debt securities in exchange for the global debt securities of that series. Global debt securities will also be exchangeable by the holders for certificated debt securities if an event of default with respect to the book-entry debt securities represented by those global debt securities has occurred and is continuing. Any certificated debt securities issued in exchange for a global debt security will be registered in such name or names as the depositary shall instruct the trustee. We expect that such instructions will be based upon directions received by the depositary from participants with respect to ownership of book-entry debt securities relating to such global debt security.

We have obtained the foregoing information concerning the depositary and the depositary’s book-entry system from sources we believe to be reliable, but we take no responsibility for the accuracy of this information.

Information Concerning the Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given to it by the indenture at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

The indenture and provisions of the Trust Indenture Act that are incorporated by reference therein contain limitations on the rights of the trustee, should it become one of our creditors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claim as security or otherwise. The trustee is permitted to engage in other transactions with us or any of our affiliates; provided, however, that if it acquires any conflicting interest (as defined in the indentures or in the Trust Indenture Act), it must eliminate such conflict or resign.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that, unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of, or any premium or interest on, any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

31

Governing Law

The indenture and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

32

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in the applicable prospectus supplements and free writing prospectuses we have authorized for use in connection with a specific offering, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, which may consist of warrants to purchase Common Stock, preferred stock or debt securities and may be issued in one or more series.

Warrants may be issued independently or together with Common Stock, preferred stock or debt securities offered by any prospectus supplement, and may be attached to or separate from those securities. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe the particular terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement and any applicable free writing prospectus we authorize for use in connection with the specific offering. The terms of any warrants offered under a prospectus supplement may differ from the terms described below.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant agreement, if any, including a form of warrant certificate, that describes the terms of the particular series of warrants we are offering. The following summaries of material provisions of the warrants and the warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to the particular series of warrants that we may offer under this prospectus. We urge you to read the applicable prospectus supplements related to the particular series of warrants that we may offer under this prospectus, as well as any related free writing prospectuses we have authorized for use in connection with a specific offering, and the complete warrant agreements and warrant certificates that contain the terms of the warrants.

General Matters

We will describe in the applicable prospectus supplement the terms relating to a series of warrants being offered, including:

33

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent in connection with the exercise of the warrant.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements, and any claim, controversy or dispute arising under or related to the warrants or warrant agreements, will be governed by and construed in accordance with the laws of the State of New York.

34

Enforceability of Rights By Holders of Warrants

Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

Warrant Agreement Will Not Be Qualified Under Trust Indenture Act

No warrant agreement will be qualified as an indenture, and no warrant agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of warrants issued under a warrant agreement will not have the protection of the Trust Indenture Act with respect to their warrants.

Calculation Agent

Calculations relating to warrants may be made by a calculation agent, an institution that we appoint as our agent for this purpose. The prospectus supplement for a particular warrant will name the institution that we have appointed to act as the calculation agent for that warrant as of the original issue date for that warrant. We may appoint a different institution to serve as calculation agent from time to time after the original issue date without the consent or notification of the holders.

The calculation agent’s determination of any amount of money payable or securities deliverable with respect to a warrant will be final and binding in the absence of manifest error.

35

DESCRIPTION OF RIGHTS

General

We may issue rights to purchase Common Stock, preferred stock, units or the other securities described in this prospectus. This prospectus and any accompanying prospectus supplement will contain the material terms and conditions for each right. The accompanying prospectus supplement may add, update or change the terms and conditions of the rights as described in this prospectus.

We will describe in the applicable prospectus supplement the terms and conditions of the issue of rights being offered, the rights agreement relating to the rights and the rights certificates representing the rights, including, as applicable:

Exercise of Rights

Each right will entitle the holder of rights to purchase for cash the principal amount of shares of Common Stock, preferred stock, units or other securities at the exercise price provided in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will be void.

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of Common Stock or preferred stock purchasable upon exercise of the rights. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters, brokers or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as described in the applicable prospectus supplement.

36

DESCRIPTION OF UNITS

We may issue units consisting of any combination of the other types of securities offered under this prospectus in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent will be a bank or trust company that we select. We will indicate the name and address of the unit agent in the applicable prospectus supplement relating to a particular series of units.

The following description, together with the additional information included in the applicable prospectus supplement, summarizes the general features of the units that we may offer under this prospectus. You should read any prospectus supplement and any free writing prospectus we authorize for use in connection with a specific offering of units, as well as the complete unit agreements that contain the terms of the units. Specific unit agreements will contain additional important terms and provisions and we will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from another report that we file with the SEC, the form of each unit agreement relating to units offered under this prospectus.

If we offer any units, certain terms of that series of units will be described in the applicable prospectus supplement, including, without limitation, the following, as applicable:

37

LEGAL OWNERSHIP OF SECURITIES

We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee or depositary maintain for this purpose as the “holders” of those securities. These persons are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as “indirect holders” of those securities. As we discuss below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.

Book-Entry Holders

We may issue securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

Only the person in whose name a security is registered is recognized as the holder of that security. Global securities will be registered in the name of the depositary or its participants. Consequently, for global securities, we will recognize only the depositary as the holder of the securities, and we will make all payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

As a result, investors in a global security will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect holders, and not legal holders, of the securities.

Street Name Holders

We may terminate a global security in certain situations, as described under “—Special Situations When a Global Security Will Be Terminated”, or issue securities that are not issued in global form. In these cases, investors may choose to hold their securities in their own names or in “street name”. Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

For securities held in street name, we or any applicable trustee or depositary will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we or any such trustee or depositary will make all payments on those securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect holders, not holders, of those securities.

Legal Holders

Our obligations, as well as the obligations of any applicable trustee or third party employed by us or a trustee, run only to the legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case

38

whether an investor chooses to be an indirect holder of a security or has no choice because we are issuing the securities only in global form.

For example, once we make a payment or give a notice to the legal holder, we have no further responsibility for the payment or notice even if that legal holder is required, under agreements with its participants or customers or by law, to pass the payment or notice along to the indirect holders but does not do so. Similarly, we may want to obtain the approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture, or for other purposes. In such an event, we would seek approval only from the legal holders, and not the indirect holders, of the securities. Whether and how the legal holders contact the indirect holders is up to the legal holders.

Special Considerations for Indirect Holders

If you hold securities through a bank, broker or other financial institution, either in book-entry form because the securities are represented by one or more global securities or in street name, you should check with your own institution to find out:

Global Securities

A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms.

Each security issued in book-entry form will be represented by a global security that we issue to, deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all securities issued in book-entry form.

A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under “—Special Situations When a Global Security Will Be Terminated”. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and legal holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a legal holder of the security, but only an indirect holder of a beneficial interest in the global security.

If the prospectus supplement for a particular security indicates that the security will be issued as a global security, then the security will be represented by a global security at all times unless and until the global security

39

is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations for Global Securities

As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security.

If securities are issued only as global securities, an investor should be aware of the following:

There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

Special Situations When a Global Security Will Be Terminated

In a few special situations described below, a global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in securities transferred to their own names, so that they will be direct holders. The rights of holders and street name investors are described above.

A global security will terminate when the following special situations occur:

40

The applicable prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the prospectus supplement. When a global security terminates, the depositary, and neither we nor any applicable trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.

41

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, direct sales to the public, “at the market” offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, or directly to one or more purchasers. We may distribute securities from time to time in one or more transactions:

A prospectus supplement or supplements (and any related free writing prospectus that we may have authorized for use in connection with a specific offering) will describe the terms of the offering of the securities, including, to the extent applicable:

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement.

If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement, other than securities covered by any over-allotment option. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

42

We may provide agents and underwriters with indemnification against civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

All securities we may offer, other than Common Stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters that are qualified market makers on the Nasdaq Capital Market may engage in passive market making transactions in the Common Stock on the Nasdaq Capital Market in accordance with Regulation M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the Common Stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

SUBJECT TO COMPLETION, DATED JANUARY 8, 2024

PROSPECTUS

SCILEX HOLDING COMPANY

Up to $170,000,000

Common Stock

On December 22, 2023, we entered into a Sales Agreement (the “Sales Agreement”), with B. Riley Securities Inc., Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC (the “Sales Agents”), relating to shares of our common stock, par value $0.0001 per share (“Common Stock”), having an aggregate offering price of up to $170,000,000. In accordance with the terms of the Sales Agreement, we may offer and sell shares of our Common Stock pursuant to this prospectus having an aggregate offering price of up to $170,000,000 from time to time through or to the Sales Agents, acting as sales agents or principals.

Sales of our Common Stock, if any, under this prospectus may be made in sales deemed to be “at the market offerings” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”). If authorized by us in writing, each Sales Agent may also sell shares of our Common Stock in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices. No Sales Agent is required to sell any specific number or dollar amount of securities, and each Sales Agent will act as a Sales Agent using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between such Sales Agent and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

The compensation to each Sales Agent for sales of Common Stock sold pursuant to the Sales Agreement will initially be equal to 3.0% of the gross proceeds of any shares of Common Stock sold under the Sales Agreement, which percentage may be adjusted based on the aggregate amount of securities sold by such Sales Agent pursuant to the Sales Agreement. In connection with the sale of the Common Stock on our behalf, each Sales Agent will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of such sales will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to each Sales Agent with respect to certain liabilities, including liabilities under the Securities Act or the Exchange Act of 1934, as amended (the “Exchange Act”).

Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described under the heading “Risk Factors” beginning on page S-8 of this prospectus and under similar headings in the documents that are incorporated by reference into this prospectus.

Our Common Stock is currently listed on the Nasdaq Capital Market under the symbol “SCLX”. On January 5, 2024, the last reported sales price for our Common Stock was $2.04 per share.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is                , 2024.

ABOUT THIS PROSPECTUS

Whenever we refer to “Scilex,” “we,” “our” or “us” in this prospectus, we mean Scilex Holding Company, unless the context suggests otherwise. When we refer to “you” or “yours,” we mean the holders of the applicable series of securities.

This prospectus is part of a “shelf” registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”), using a “shelf” registration process. This prospectus describes the specific terms of this offering of shares of Common Stock and also adds to and updates information contained in the documents incorporated by reference into this prospectus.

This prospectus relates only to an offering of up to $170,000,000 of shares of our Common Stock through the Sales Agents. These sales, if any, will be made pursuant to the terms of the Sales Agreement entered into among us and B. Riley Securities Inc., Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC on December 22, 2023, a copy of which is filed as an exhibit to the registration statement of which this prospectus is a part.

Before you invest, you should carefully read this prospectus, all information incorporated by reference herein and the additional information described under “Where You Can Find More Information” and “Important Information Incorporated by Reference”. These documents contain information you should consider when making your investment decision. To the extent that any statement that we make in this prospectus is inconsistent with statements made in any documents incorporated by reference, the statements made in this prospectus will be deemed to modify or supersede those made in such documents incorporated by reference; however, if any statement in one of these documents is inconsistent with a statement in another document having a later date and that is incorporated by reference herein, the statement in the document having the later date modifies or supersedes the earlier statement.

You should rely only on the information contained or incorporated by reference in this prospectus, the documents incorporated by reference herein and any free writing prospectus we may provide you. We have not, and no Sales Agent has, authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and no Sales Agent is, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted.

Our business, financial condition, results of operations and prospects may have changed since those dates. You should read this prospectus, including the documents incorporated by reference herein, when making your investment decision.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before you make a decision to buy our securities, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements”, you should carefully consider the risks and uncertainties described under the section titled “Risk Factors” contained in our most recent Annual Report on Form 10-K, together with all of the other information appearing in or incorporated by reference into this prospectus, as updated by our subsequent filings with the SEC, as well as the risk factors and other information contained in any applicable prospectus supplement and any applicable free writing prospectus before deciding to invest in our securities. If any of these risks actually occurs, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus, any prospectus supplement, any post-effective amendment or in any filing or document incorporated by reference herein or therein are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Related to This Offering

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes, which may include capital expenditures, commercialization expenditures, research and development expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock, as further described in the section of this prospectus entitled “Use of Proceeds”. We will have broad discretion in the application of the net proceeds in the category of other working capital and general corporate purposes and investors will be relying on the judgment of our management regarding the application of the proceeds of this offering.

The precise amount and timing of the application of these proceeds will depend upon a number of factors, such as the timing and progress of our research and development efforts, our funding requirements and the availability and costs of other funds. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Depending on the outcome of our efforts and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate.

The failure by our management to apply these funds effectively could harm our business, financial condition and results of operations. Pending their use, we may invest the net proceeds from this offering in short-term, interest-bearing instruments. These investments may not yield a favorable return to our stockholders.

You may experience immediate and substantial dilution.

Because the prices per share at which shares of our Common Stock are sold in this offering may be substantially higher than the net tangible book value per share of our Common Stock, you may suffer immediate and substantial dilution in the net tangible book value of the Common Stock you purchase in this offering. The shares sold in this offering, if any, will be sold from time to time at various prices. If we sell shares in this offering at a price that is higher than the net tangible book value per share of our Common Stock, investors in this offering will experience dilution. The exercise of outstanding stock options and warrants, and the vesting of outstanding restricted stock units, may result in further dilution of your investment. See the section of this prospectus entitled “Dilution” for a more detailed illustration of the dilution you would incur if you participate in this offering.

S-8

The shares of Common Stock will be sold in “at the market” offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and number of shares sold in this offering. In addition, subject to the final determination by our board of directors or any restrictions we may place in any applicable placement notice, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

The actual number of shares we will issue under the Sales Agreement with the Sales Agents, at any one time or in total, is uncertain.

Subject to certain limitations in the Sales Agreement with the Sales Agents and compliance with applicable law, we have the discretion to deliver placement notices to each Sales Agent at any time throughout the term of the Sales Agreement. The number of shares that are sold by each Sales Agent after delivering a placement notice will fluctuate based on the market price of the Common Stock during the sales period and limits we set with such Sales Agent.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our Common Stock or other securities convertible into or exchangeable for our Common Stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our Common Stock, or securities convertible or exchangeable into Common Stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

We have not paid cash dividends in the past and we do not expect to pay cash dividends in the foreseeable future. Any return on investment may be limited to the capital appreciation, if any, of our Common Stock.

We have not paid cash dividends on our Common Stock and we do not anticipate paying cash dividends on our Common Stock in the foreseeable future. Should we decide in the future to do so, as a holding company, our ability to pay dividends on our capital stock and meet other obligations depends upon the receipt of dividends or other payments from our operating subsidiaries. In addition, our ability to pay dividends may be limited by covenants in future outstanding indebtedness that we or our subsidiaries may incur. Since we do not intend to pay dividends, a stockholder’s ability to receive a return on such stockholder’s investment will depend on any future appreciation in the market value of our Common Stock. There is no guarantee that our Common Stock will appreciate or even maintain the price at which our stockholders have purchased it.

The market price of our Common Stock may fluctuate significantly, and investors in our Common Stock may lose all or a part of their investment.

The market prices for securities of biotechnology and pharmaceutical companies have historically been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. For example, from November 11, 2022 (the first trading day following the closing of the Business Combination) to January 5, 2024, our closing stock price ranged from $0.95 to $14.80. The market price of our Common Stock may fluctuate significantly in response to numerous factors, some of which are beyond our control.

S-9

Sales of a significant number of shares of Common Stock in the public markets, or the perception that such sales could occur, could depress the market price of our Common Stock.

Sales of a substantial number of shares in the public markets, or the perception that such sales could occur, could depress the market price of our Common Stock and impair our ability to raise capital through the sale of additional equity securities. We have agreed, without the prior written consent of the Sales Agents, and subject to certain exceptions set forth in the Sales Agreement, not to sell or otherwise dispose of any Common Stock or securities convertible into or exchangeable for shares of Common Stock, warrants or any rights to purchase or acquire Common Stock during the period beginning on the fifth trading day immediately prior to the delivery of any placement notice delivered by us to any Sales Agent and ending on the fifth trading day immediately following the final settlement date with respect to the shares sold pursuant to such notice. We have further agreed, subject to certain exceptions set forth in the Sales Agreement, not to sell or otherwise dispose of any Common Stock or securities convertible into or exchangeable for shares of Common Stock, warrants or any rights to purchase or acquire Common Stock in any other “at the market offering” or continuous equity transaction prior to the sixtieth day immediately following the termination of the Sales Agreement with the Sales Agents. Therefore, it is possible that we could issue and sell additional shares of our Common Stock in the public markets. We cannot predict the effect that future sales of our Common Stock would have on the market price of our Common Stock.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference into this prospectus may contain forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act, about us and our subsidiaries. These forward-looking statements are intended to be covered by the safe harbor for forward-looking statements provided by the Private Securities Litigation Reform Act of 1995. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. These forward-looking statements rely on a number of assumptions concerning future events and include statements relating to:

Any forward-looking statements should be considered in light of these factors. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “contemplate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “will,” “would” and other similar words and expressions (including the negative of any of the foregoing), but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements are based on

S-11

information available as of the date of this prospectus and our management’s current expectations, forecasts and assumptions, and involve a number of judgments, known and unknown risks and uncertainties and other factors, many of which are outside the control of the Company and our directors, officers and affiliates. There can be no assurance that future developments will be those that have been anticipated. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date. You are cautioned not to put undue reliance on any forward-looking statements. Except as otherwise required by law, we do not assume any obligation to update any forward-looking statements.

You should read this prospectus and the documents incorporated by reference completely and with the understanding that our actual future results may be materially different from what we currently expect. Our business and operations are and will be subject to a variety of risks, uncertainties and other factors. Consequently, actual results and experience may materially differ from those contained in any forward-looking statements. Such risks, uncertainties and other factors that could cause actual results and experience to differ from those projected include, but are not limited to, the risk factors set forth in Part I —Item  1A, “Risk Factors”, in our Annual Report on Form  10-K for the year ended December 31, 2022 and Part II—Item 1A, “Risk Factors”, in our Quarterly Reports on Form  10-Q for the quarters ended March  31, 2023, June  30, 2023 and September 30, 2023 and in other filings with the SEC, which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future, that are incorporated by reference in this prospectus.

You should assume that the information appearing in this prospectus and any document incorporated herein by reference is accurate as of its date only. Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf, you should not place undue reliance on any forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made. New factors emerge from time to time, and it is not possible for us to predict which factors will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Some of these risks and uncertainties may in the future be amplified by COVID-19 (or other similar disruptions), and there may be additional risks that we consider immaterial or which are unknown. It is not possible to predict or identify all such risks. All written or oral forward-looking statements attributable to us or any person acting on our behalf made after the date of this prospectus are expressly qualified in their entirety by the risk factors and cautionary statements contained in and incorporated by reference into this prospectus. Unless legally required, we do not undertake any obligation to release publicly any revisions to such forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events.

MARKET AND INDUSTRY DATA

Certain information contained in this prospectus relates to or is based on studies, publications, surveys and other data obtained from third-party sources and our own internal estimates and research. While we believe these third-party sources to be reliable as of the date of this prospectus, we have not independently verified the market and industry data contained in this prospectus or the underlying assumptions relied on therein. Finally, while we believe our own internal research is reliable, such research has not been verified by any independent source. Notwithstanding the foregoing, we are liable for the information provided in this prospectus. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the section of this prospectus titled “Risk Factors”. These and other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by us.

S-13

USE OF PROCEEDS

We currently intend to use the net proceeds from the sale of our Common Stock offered by this prospectus for working capital and general corporate purposes, which may include capital expenditures, commercialization expenditures, research and development expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock.

The precise amount and timing of the application of these proceeds will depend upon a number of factors, such as the costs and timing of commercial and development activities, including, for example, conducting preclinical studies and clinical trials, our funding requirements and the availability and costs of other funds. Pending application of the net proceeds as described above, we intend to temporarily invest the proceeds in interest-bearing instruments.

We may bear all other costs, fees and expenses incurred in effecting the registration of the shares covered by this prospectus, including, without limitation, all registration and filing fees, Nasdaq Capital Market listing fees, and fees and expenses of our counsel and our accountants.

S-14

DILUTION

If you purchase our Common Stock in this offering, your interest will be diluted to the extent of the difference between the public offering price per share and the net tangible book value per share of our Common Stock after this offering.

As of September 30, 2023, we had net tangible book value of approximately $(213,661,000), or $(1.39) per share. Net tangible book value per share represents the amount of total tangible assets less total liabilities divided by the number of shares of our Common Stock outstanding.

Our pro forma net tangible book value as of September 30, 2023, before giving effect to this offering, was approximately $(208,438,000), or $(1.32) per share of our Common Stock. Pro forma net tangible book value, before the issuance and sale of shares of Common Stock in this offering, gives effect to the issuance of an aggregate of 3,720,566 shares of Common Stock after September 30, 2023 and on or prior to November 30, 2023 (comprised of (i) an aggregate of 3,718,465 shares of Common Stock issued pursuant to advances made under the Company’s existing standby equity lines of credit and (ii) 2,101 shares of Common Stock issued upon exercise of outstanding stock options), and assumes that following November 30, 2023 we have not issued any additional shares of Common Stock.

After giving effect to (i) the pro forma adjustments set forth above and (ii) the sale of 130,769,230 shares of Common Stock at an assumed public offering price of $1.30 per share, the last reported sale price of our Common Stock on the Nasdaq Capital Market on December 20, 2023, after deducting commissions at an assumed rate of 3.0% and estimated aggregate offering expenses payable by us, our pro forma as adjusted net tangible book value as of September 30, 2023 would have been approximately $(44,138,000), or approximately $(0.15) per share. This amount represents an immediate increase in pro forma net tangible book value of approximately $1.17 per share to our existing stockholders and an immediate dilution in net tangible book value of approximately $1.45 per share to new investors purchasing shares of Common Stock in this offering.

Dilution per share to new investors is determined by subtracting pro forma as adjusted net tangible book value per share after this offering from the offering price per share paid by new investors. The following table illustrates this dilution:

The table above assumes for illustrative purposes that an aggregate of 130,769,230 additional shares of our Common Stock are sold pursuant to the Sales Agreement with the Sales Agents at a price of $1.30 per share, the last reported sale price of our Common Stock on the Nasdaq Capital Market on December 20, 2023, for aggregate net proceeds of approximately $164,300,000, after deducting commissions at an assumed rate of 3.0% and estimated aggregate offering expenses payable by us. The shares pursuant to the Sales Agreement with the Sales Agents are being sold from time to time at various prices. The pro forma as adjusted information is

S-15

illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time shares of our Common Stock are sold pursuant to this prospectus.

An increase of $1.00 per share in the price at which the shares are sold from the assumed offering price of $1.30 per share shown in the table above, assuming all of our Common Stock in the aggregate amount of $170,000,000 pursuant to the Sales Agreement with the Sales Agents is sold at that price, would increase our pro forma as adjusted net tangible book value per share after the offering to $0.28 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $2.02 per share, after deducting commissions at an assumed rate of 3.0% and estimated aggregate offering expenses payable by us. A decrease of $1.00 per share in the price at which the shares are sold from the assumed offering price of $1.30 per share shown in the table above, assuming all of our Common Stock in the aggregate amount of $170,000,000 pursuant to the Sales Agreement with the Sales Agents is sold at that price, would decrease our pro forma as adjusted net tangible book value per share after the offering to $(0.59) per share and would decrease the dilution in pro forma net tangible book value per share to new investors in this offering to $0.89 per share, after deducting commissions at an assumed rate of 3.0% and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only.

The above discussion and table are based on 154,185,089 shares of our Common Stock issued and outstanding as of September 30, 2023 and excludes the following:

To the extent that options or warrants outstanding as of September 30, 2023 have been or are exercised, new options or other equity awards are granted under our equity incentive plans, or we issue additional shares in the future, investors purchasing shares in this offering could experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

S-16

PLAN OF DISTRIBUTION

We entered into the Sales Agreement with the Sales Agents on December 22, 2023, pursuant to which we may issue and sell from time to time shares of our Common Stock having an aggregate offering price of up to $170,000,000, to or through B. Riley Securities Inc., Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC, acting as our Sales Agents. A copy of the Sales Agreement was filed as Exhibit 1.1 to the Registration Statement on Form S-3 of which this prospectus forms a part, and is incorporated by reference into this prospectus.

The sales of our Common Stock, if any, under this prospectus will be made at market prices by any method deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on the Nasdaq Capital Market, on any other existing trading market for our Common Stock or to or through a market maker.

Each time that we wish to issue and sell shares of our Common Stock under the Sales Agreement, we will provide a Sales Agent with a placement notice describing the amount of shares to be sold, the time period during which sales are requested to be made, any limitation on the amount of shares of Common Stock that may be sold in any single day, any minimum price below which sales may not be made or any minimum price requested for sales in a given time period and any other instructions relevant to such requested sales. Upon receipt of a placement notice, the applicable Sales Agent, acting as our sales agent, will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Capital Market, to sell shares of our Common Stock under the terms and subject to the conditions of the placement notice and the Sales Agreement. We or each Sales Agent may suspend the offering of Common Stock pursuant to a placement notice upon notice and subject to other conditions.

Settlement for sales of Common Stock, unless the parties agree otherwise, will occur on the second trading day following the date on which any sales are made in return for payment of the net proceeds to us. There are no arrangements to place any of the proceeds of this offering in an escrow, trust or similar account. Sales of our Common Stock as contemplated in this prospectus will be settled through the facilities of The Depository Trust Company or by such other means as we and each Sales Agent may agree upon.

We will pay the Sales Agents commissions for their services in acting as our sales agents in the sale of our Common Stock pursuant to the Sales Agreement. A Sales Agent will be entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of our Common Stock on our behalf pursuant to the Sales Agreement. We have also agreed to reimburse the Sales Agents for their reasonable and documented out-of-pocket expenses (including but not limited to the reasonable and documented fees and expenses of their legal counsel) in an amount not to exceed $35,000 in the aggregate (excluding any periodic due diligence fees for which Sales Agents’ counsel will receive up to a maximum of $5,000 per due diligence update session, if any, conducted in connection with our Quarterly Reports on Form 10-Q and $10,000 per due diligence update session, if any, conducted in connection with our Annual Report on Form 10-K, in each case in accordance with the terms of the Sales Agreement). We estimate such due diligence fees would not exceed $75,000 over the three year term of the Sales Agreement.

We estimate that the total expenses for this offering, excluding compensation payable to the Sales Agents and certain expenses reimbursable to the Sales Agents under the terms of the Sales Agreement, will be approximately $600,000. The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such Common Stock.

Because there are no minimum sale requirements as a condition to this offering, the actual total public offering price, commissions and net proceeds to us, if any, are not determinable at this time. The actual dollar amount and number of shares of Common Stock we sell through this prospectus will be dependent, among other things, on market conditions and our capital raising requirements.

S-17

We will report at least quarterly the number of shares of Common Stock sold through the Sales Agents under the Sales Agreement, the net proceeds to us and the compensation paid by us to the Sales Agents in connection with the sales of Common Stock under the Sales Agreement.

In connection with the sale of the Common Stock on our behalf, each Sales Agent will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of the Sales Agents will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to the Sales Agents against certain civil liabilities, including liabilities under the Securities Act.

The Sales Agents will not engage in any market making activities involving our Common Stock while the offering is ongoing under this prospectus if such activity would be prohibited under Regulation M or other anti-manipulation rules under the Securities Act. As our sales agents, the Sales Agents will not engage in any transactions that stabilize our Common Stock.

The offering pursuant to the Sales Agreement will terminate upon the earlier of (i) the sale of all shares of Common Stock subject to the Sales Agreement and (ii) termination of the Sales Agreement as permitted therein. We may terminate the Sales Agreement in our sole discretion at any time by giving three business days’ prior notice to the Sales Agents. Each Sales Agent may terminate the Sales Agreement with respect to itself under the circumstances specified in the Sales Agreement and in their sole discretion at any time by giving three business days’ prior notice to us.

The Sales Agents and/or their affiliates have provided, and may in the future provide, various investment banking and other financial services for us, for which services they have received and may in the future receive customary fees.

This prospectus in electronic format may be made available on a website maintained by any of the Sales Agents, and the Sales Agents may distribute this prospectus electronically.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following table sets forth the estimated costs and expenses, other than underwriting discounts and commissions, payable by Scilex Holding Company (the “Registrant”), in connection with the sale of the securities being registered. All the amounts shown are estimates, except for the SEC registration fee and the FINRA filing fee.

Item 15. Indemnification of Directors and Officers

Section 102 of the General Corporation Law of the State of Delaware (“DGCL”) permits a corporation to eliminate or limit the personal liability of directors and officers of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director or officer, except where the director or officer breached his or her duty of loyalty to the corporation or its stockholders, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase or redemption in violation of the DGCL or derived an improper personal benefit, or, with respect to any officer, any action by or in the right of the corporation. The Registrant’s restated certificate of incorporation (the “Certificate of Incorporation”) contains provisions that limit the liability of the Registrant’s directors and officers for monetary damages to the fullest extent permitted by the DGCL. Consequently, the Registrant’s directors and officers will not be personally liable to the Registrant or its stockholders for monetary damages for any breach of fiduciary duty as a director or officer, except liability for the following:

II-1

The Certificate of Incorporation also provides that if the DGCL is amended to permit further elimination or limitation of the personal liability of directors or officers, then the liability of the Registrant’s directors and officers will be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Section 145 of the DGCL provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation, or a person serving at the request of the corporation for another corporation, partnership, joint venture, trust or other enterprise in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he or she was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to judgments, fines and amounts paid in settlement in connection with such action, suit or proceeding or with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. The Certificate of Incorporation permits the Registrant to indemnify its directors, officers, employees and other agents to the maximum extent permitted by the DGCL, and the Registrant’s bylaws provide that the Registrant will indemnify its directors and officers and permit the Registrant to indemnify its employees and other agents, in each case to the extent not prohibited by the DGCL or any other applicable law.

The Registrant has entered, and expects to continue to enter, into indemnification agreements with its directors and officers, that may be broader than the specific indemnification provisions contained in the DGCL. These agreements, among other things, require the Registrant to indemnify its directors and officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require the Registrant to advance all expenses actually and reasonably incurred by the directors and executive officers in connection with any proceeding. The Registrant also maintains directors’ and officers’ liability insurance.

Item 17. Undertakings

The undersigned Registrant hereby undertakes:

Provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

II-10

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by

II-11

a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

II-12
