TABLE OF CONTENTS

OUR COMPANY

Overview

We are a new type of pharmaceutical company committed to developing and expanding access to innovative medicines for some of the most prevalent disease areas, including cancer and immune-inflammatory conditions. Launched in January 2020, we are leveraging cutting-edge science, technology and strategic partnerships with stakeholders from across the healthcare system toward the goal of increasing access for patients around the world.

Today, we have more than 10 programs in our pipeline including clinical, preclinical and drug engineering targets for the treatment of oncology and immune-inflammatory conditions. We will continue to evaluate opportunities to add to our pipeline by in-licensing additional programs, leveraging our drug engineering collaborations and exploring combination partnerships. Select late-stage programs, each in-licensed in 2020, include: aumolertinib (EQ143), a third-generation epidermal growth factor receptor (EGFR) inhibitor; lerociclib (EQ132), a cyclin-dependent kinase (CDK) 4/6 inhibitor; and sugemalimab (EQ165, also known as CS1001), an anti-programmed death-ligand 1 (PD-L1) antibody.

We are in ongoing discussions with regulatory authorities in several geographies. Our marketing authorization applications for aumolertinib for the first-line (1L) treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with activating EGFR mutations and those with locally advanced or metastatic EGFR T790M mutation-positive NSCLC were accepted for review by the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) for a Great Britain license in June 2022 and by the European Medicines Agency (EMA) for a European Union-wide license in December 2022. Our marketing authorization applications for sugemalimab in combination with chemotherapy for the 1L treatment of adult patients with metastatic NSCLC were accepted for review by the MHRA for a Great Britain license in December 2022 and by the EMA for a European Union-wide license in February 2023. Based on discussions with the the U.S. Food and Drug Administration (FDA), in November 2022 and February 2023, we determined not to seek U.S. regulatory approval for sugemalimab in Stage IV NSCLC or in ENKTL, respectively.

Summary of Risks Associated with Our Business

Our ability to implement our business strategy is subject to numerous risks that you should be aware of before making an investment decision. These risks are described more fully in the section entitled “Risk Factors,” following this prospectus summary. These risks include the following, among others:

•

We do not have any products approved for commercial sale and have not generated any revenue to date, and so may never become profitable.

•

We may not be successful in adapting our initial commercial and pricing models, plans and strategies to accommodate the U.S. regulatory environment.

•

Our initial commercial and pricing models are untested, and even with the planned adaptation of our models, plans and strategies and initial regulatory filings ex-United States, we may never be successful or generate sufficient revenue to lead to profitability.

•

We recently determined not to seek regulatory approval in the United States for sugemalimab in Stage IV non-small cell lung cancer (NSCLC) or in extranodal NK/T-cell lymphoma (ENKTL), and we may make similar decisions for other indications, other markets, and/or our other pipeline candidates, which will impact the revenues we may generate from our pipeline candidates when and if approved.

•

In jurisdictions in which regulators do not solely accept data from our license partners from other countries but instead require additional data generated from additional preclinical studies and clinical trials as a basis for regulatory approvals (such as the U.S. Food and Drug Administration (FDA)), we will incur additional costs and experience delays in completing, or ultimately be unable to complete, the development of such product candidate; we may also choose not to pursue development for certain indications in that market given the potential increased costs or delays, or

TABLE OF CONTENTS

impact on our ability to complete the development of such product candidate (such as our decisions not to seek FDA approval of sugemalimab in Stage IV NSCLC and ENKTL).

•

Drug development is a lengthy, expensive and uncertain process. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of a product candidate. Even if we achieve positive clinical trial results, there is no guarantee that our product candidates will be approved. Our competitors may also obtain FDA or other regulatory approval for their products sooner than we may obtain approval for ours and for multiple indications in parallel, which could require us to undertake additional trials and also result in our competitors establishing a strong market position before we or our collaborators are able to enter the market. If we experience delays in obtaining data from our license partners, their other licensees or other collaborators, or other relevant third parties, or we experience delays or difficulties in the initiation or enrollment of our clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.

•

We have never successfully completed the regulatory approval process for any of our product candidates, and we may be unable to do so for any product candidates. Even if we are successful in obtaining regulatory approval in one indication or jurisdiction for a product candidate, it does not guarantee that we will be able to obtain pricing approval in such jurisdiction, that our products will be broadly adopted in such jurisdiction, or that we will be able to obtain regulatory approval in any other indication or jurisdiction. Further, even if we receive regulatory approval for any of our current or future product candidates, we will be subject to ongoing obligations and continued regulatory review, which may result in significant additional expense.

•

We may adopt market-based pricing for other product candidates beyond aumolertinib and lerociclib in the United States, and may need to abandon our initial mission to develop and deliver innovative medicines to patients at lower prices.

•

We may be unsuccessful in achieving broad market awareness and acceptance or changing prescribing or purchasing habits of healthcare system participants or keeping up to date with recent developments in the medical field regarding treatment options.

•

We may be unable to continue to attract, acquire and retain third-party collaborators, particularly as we adapt our initial commercial and pricing models, plans and strategies, or we may fail to do so in an effective manner. Our collaborations with third parties are also subject to certain risks.

•

Our financial projections are subject to significant risks, assumptions, estimates and uncertainties, and our actual results may differ materially.

•

Our current or future product candidates may cause adverse or other undesirable side effects that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

•

If we (or our collaboration and license partners, as applicable) are unable to obtain and maintain patent and other intellectual property protection for our technology and product candidates, or if the scope of the intellectual property protection obtained is not sufficiently broad, our competitors could develop and commercialize technology and drugs similar or identical to ours, and our ability to successfully commercialize our technology and drugs may be impaired.

•

Our failure to manage growth effectively could cause our business to suffer and have an adverse effect on our ability to execute our business strategy, as well as on our operating results and financial condition.

If any of these risks actually occur, 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. When determining whether to invest, you should also refer to the other information in this prospectus and the documents incorporated by reference, including our financial statements and the related notes thereto, and the other financial information concerning us included elsewhere in this prospectus. Additionally, the risks and uncertainties described in this prospectus or any prospectus supplement 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.

TABLE OF CONTENTS

USE OF PROCEEDS

All of the Common Stock and Warrants offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective accounts. We will not receive any of the proceeds from these sales.

We will receive up to an aggregate of approximately $226.9 million from the exercise of the Warrants, assuming the exercise in full of all of the Warrants for cash. We expect to use the net proceeds from the exercise of the Warrants for general corporate purposes. We will have broad discretion over the use of proceeds from the exercise of the Warrants. There is no assurance that the holders of the Warrants will elect to exercise any or all of such Warrants. To the extent that the Warrants are exercised on a “cashless basis,” the amount of cash we would receive from the exercise of the Warrants will decrease.

SELLING SECURITYHOLDERS

Certain of the Selling Securityholders acquired the shares of Common Stock and Placement Warrants from us in private offerings pursuant to exemptions from registration under Section 4(a)(2) of the Securities Act in connection with a private placement concurrent with our IPO and in connection with the Merger. Pursuant to the Registration Rights Agreement signed April 6, 2021, which was amended and restated at the closing of the Merger (the Amended and Restated Registration Rights Agreement), the Subscription Agreements and the Warrant Agreement, we agreed to file a registration statement with the SEC for the purposes of registering for resale (i) the Placement Warrants (and the shares of Common Stock that may be issued upon exercise of the Placement Warrants), and (ii) the shares of Common Stock issued to the Selling Securityholders pursuant to the Subscription Agreements and the Merger Agreement.

Except as set forth in the footnotes below, the following table sets forth, based on written representations from the Selling Securityholders, certain information as of the Closing Date regarding the ownership of Common Stock and Warrants by the Selling Securityholders. The shares of Common Stock owned and being offered by the Selling Securityholders assumes the exercise in full of all outstanding options or Warrants held by such Selling Securityholder. A Selling Securityholder may have sold or transferred some or all of the Common Stock indicated below with respect to such Selling Securityholder and may in the future sell or transfer some or all of the Common Stock indicated below in transactions exempt from the registration requirements of the Securities Act rather than under this prospectus. The applicable percentage ownership of Common Stock is based on approximately 488,549,210 shares of Common Stock outstanding as of December 31, 2022. Information with respect to shares of Common Stock and Placement Warrants owned after the offering assumes the sale of all of the shares of Common Stock and Placement Warrants offered hereby and no other purchases or sales of Common Stock or Placement Warrants. The Selling Securityholders may offer and sell some, all or none of their shares of Common Stock or Placement Warrants, as applicable.

Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the Selling Securityholders have sole voting and investment power with respect to all shares of Common Stock and Warrants that they own, subject to applicable community property laws. Except as otherwise described below, based on the information provided to us by the Selling Securityholders, no Selling Securityholder is a broker-dealer or an affiliate of a broker-dealer. Up to 11,039,957 shares of Common Stock issuable upon exercise of the Public Warrants are not included in the table below, unless specifically indicated in the footnotes therein.

TABLE OF CONTENTS

DESCRIPTION OF SECURITIES

The following summary of the material terms of our securities is not intended to be a complete summary of the rights and preferences of such securities, and is qualified by reference to the Certificate of Incorporation, the Bylaws and the Warrant-related documents described herein, which are exhibits to the registration statement of which this prospectus is a part. We urge you to read each of the Certificate of Incorporation, the Bylaws and the Warrant-related documents described herein and the applicable provisions of the DGCL in their entirety for a complete description of the rights and preferences of our securities.

Certificate of Incorporation

Authorized Stock

The Certificate of Incorporation authorizes two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares of capital stock that we have authority to issue is 1,252,000,000. The total number of shares of Common Stock that we are authorized to issue is 1,250,000,000, having a par value of $0.0001 per share, and the total number of shares of Preferred Stock that we are authorized to issue is 2,000,000, having a par value of $0.0001 per share.

Common Stock

The Certificate of Incorporation provides that the Common Stock has the following rights, powers, preferences and privileges.

General

The voting, dividend, liquidation and other rights and powers of the Common Stock are subject to and qualified by the rights, powers and preferences of any series of Preferred Stock as may be designated by the Board and outstanding from time to time.

Voting Power

Except as otherwise provided herein or expressly required by law, each holder of Common Stock, as such, is entitled to vote on each matter submitted to a vote of stockholders and is entitled to one vote for each share of Common Stock held of record by such holder as of the record date for determining stockholders entitled to vote on such matter. Except as otherwise required by law, holders of Common Stock, as such, are not entitled to vote on any amendment to Certificate of Incorporation (including any Certificate of Designation (as defined below)) that relates solely to the rights, powers, preferences (or the qualifications, limitations or restrictions thereof) or other terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation (including any Certificate of Designation) or pursuant to the DGCL.

Subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of our stock entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Dividends

Subject to applicable law and the rights and preferences of any holders of any outstanding series of Preferred Stock, the holders of Common Stock, as such, are entitled to the payment of dividends on the Common Stock when, as and if declared by the Board in accordance with applicable law.

Liquidation

Subject to the rights and preferences of any holders of any shares of any outstanding series of Preferred Stock, in the event of any liquidation, dissolution or winding up of our company, whether voluntary or

TABLE OF CONTENTS

involuntary, our funds and assets that may be legally distributed to our stockholders will be distributed among the holders of the then outstanding Common Stock pro rata in accordance with the number of shares of Common Stock held by each such holder.

Transfer Rights

Subject to applicable law and the transfer restrictions set forth in Article VII of the Bylaws, shares of Common Stock and the rights and obligations associated therewith are fully transferable to any transferee.

Preferred Stock

Shares of Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and in the resolution or resolutions providing for the creation and issuance of such series adopted by the Board as hereinafter provided.

Authority is expressly granted to the Board from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuance of the shares thereof and by filing a certificate of designation relating thereto in accordance with the DGCL (a Certificate of Designation), to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, and to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series as stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the DGCL. Without limiting the generality of the foregoing, the resolution or resolutions providing for the creation and issuance of any series of Preferred Stock may provide that such series is superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law and the Certificate of Incorporation (including any Certificate of Designation). Except as otherwise required by law, holders of any series of Preferred Stock will be entitled only to such voting rights, if any, as shall expressly be granted thereto by the Certificate of Incorporation (including any Certificate of Designation).

The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of our stock entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Warrants

Public Warrants

Our Public Warrants are the warrants underlying the units we issued in our IPO. Each whole Public Warrant now entitles the registered holder to purchase one share of our Common Stock at a price of $11.50 per whole share, subject to adjustment as discussed below, at any time. Pursuant to that certain Warrant Agreement, dated April 6, 2021, between our company and Continental Stock Transfer & Trust Company, as the warrant agent (the Warrant Agreement), a warrant holder may exercise its Public Warrants only for a whole number of shares of Common Stock. This means that only a whole Public Warrant may be exercised at any given time by a warrant holder. If, upon exercise of the Public Warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to the warrant holder. As a result, warrant holders not purchasing Public Warrants in multiples of three will not obtain value from the fractional interest that will not be issued. Only whole Public Warrants will trade. The Public Warrants will expire December 17, 2026 (i.e., five years after the completion of the Business Combination), at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We are not obligated to deliver any shares of Common Stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such exercise unless a registration statement under the Securities Act with respect to the shares of Common Stock underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with

TABLE OF CONTENTS

respect to registration. No Public Warrant will be exercisable for cash or on a cashless basis, and we will not be obligated to issue any shares to holders seeking to exercise their Public Warrants, unless the issuance of the shares upon such exercise is registered or qualified under the securities laws of the state of the exercising holder, or an exemption is available. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Public Warrant, the holder of such Public Warrant will not be entitled to exercise such Public Warrant and such Public Warrant may have no value and expire worthless.

We have registered under the Securities Act the issuance of shares of Common Stock upon exercise of the Public Warrants. We will use our best efforts to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Public Warrants in accordance with the provisions of the Warrant Agreement. Notwithstanding the above, if our Common Stock is at the time of any exercise of a Public Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, we may, at our option, require holders of Public Warrants who exercise their Public Warrants to do so a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) and, in the event we so elect, we will not be required to file or maintain in effect a registration statement, but will use our best efforts to register the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of Warrants When the Price per Share of Common Stock Equals or Exceeds $18.00 — We may redeem the outstanding Public Warrants:

•

in whole and not in part;

•

at a price of $0.01 per Public Warrant;

•

upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

•

if, and only if, the closing price of the Common Stock equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three trading days before sending the notice of redemption to warrant holders.

If and when the Warrants become redeemable, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws.

Redemption of Warrants When the Price per Share of Common Stock Equals or Exceeds $10.00 — Once the Warrants become exercisable, we may redeem the outstanding Warrants:

•

in whole and not in part;

•

at $0.10 per Warrant upon a minimum of 30 days’ prior written notice of redemption provided that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive that number of shares based on the redemption date and the fair market value of the Common Stock;

•

if, and only if, the closing price of the Common Stock equals or exceeds $10.00 per share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before we send the notice of redemption to the warrant holders; and

•

if the closing price of the Common Stock for any 20 trading days within a 30-trading day period ending three trading days before we send notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the private placement warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

The private placement warrants are identical to the Public Warrants underlying the units sold in the IPO, except that (1) the private placement warrants and the Common Stock issuable upon the exercise of the private placement warrants were not transferable, assignable or able to be sold until 30 days after the completion of the Business Combination, subject to certain limited exceptions, (2) the private placement warrants are exercisable on a cashless basis, (3) the private placement warrants are non-redeemable (except as described above in “Redemption of Warrants When the Price per Share of Common Stock Equals or Exceeds $10.00”) so long as they are held by the initial purchasers or their permitted

TABLE OF CONTENTS

transferees, and (4) the holders of the private placement warrants and the Common Stock issuable upon the exercise of the private placement warrants have certain registration rights. If the private placement warrants are held by someone other than the initial purchasers or their permitted transferees, the private placement warrants will be redeemable by us and exercisable by such holders on the same basis as the Public Warrants.

We have established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Public Warrants, each warrant holder will be entitled to exercise his, her or its Public Warrant prior to the scheduled redemption date. However, the price of the Common Stock may fall below the $18.00 redemption trigger price as well as the $11.50 warrant exercise price after the redemption notice is issued.

Redemption procedures and cashless exercise. If we call the Public Warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise his, her or its Public Warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their Public Warrants on a “cashless basis,” our management will consider, among other factors, our cash position, the number of Public Warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of Common Stock issuable upon the exercise of our Public Warrants. If our management takes advantage of this option, all holders of Public Warrants would pay the exercise price by surrendering their Public Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (i) the product of the number of shares of Common Stock underlying the Public Warrants, multiplied by the difference between the exercise price of the Public Warrants and the “fair market value” (defined below) by (ii) the fair market value. The “fair market value” means the average reported last sale price of the 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 Public Warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Public Warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. We believe this feature is an attractive option to us if we do not need the cash from the exercise of the Public Warrants. If we call our Public Warrants for redemption and our management does not take advantage of this option, the Sponsor and its permitted transferees would still be entitled to exercise their private placement warrants for cash or on a cashless basis using the same formula described above that other warrant holders would have been required to use had all warrant holders been required to exercise their Public Warrants on a cashless basis, as described in more detail below.

A holder of a Public Warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such Public Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the warrant agent’s actual knowledge, would beneficially own in excess of 9.8% (or such other amount as a holder may specify) of the shares of Common Stock outstanding immediately after giving effect to such exercise.

Anti-dilution Adjustments. If the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Public Warrant will be increased in proportion to such increase in the outstanding shares of Common Stock. A rights offering to holders of Common Stock entitling holders to purchase shares of Common Stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Common Stock) multiplied by (ii) one minus the quotient of (a) the price per share of Common Stock paid in such rights offering divided by (b) the fair market value. For these purposes (1) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (2) fair market value means the volume weighted average price of

TABLE OF CONTENTS

Common Stock as reported during the 10 trading day period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the Public Warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders of Common Stock on account of such shares of Common Stock (or other shares of our capital stock into which the Public Warrants are convertible), other than (i) as described above or (ii) certain ordinary cash dividends, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of Common Stock in respect of such event.

If the number of outstanding shares of our Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Public Warrant will be decreased in proportion to such decrease in outstanding shares of Common Stock.

Whenever the number of shares of Common Stock purchasable upon the exercise of the Public Warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the 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 Public 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.

In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than those described above or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the Public Warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Public Warrants and in lieu of the shares of our Common Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Public Warrants would have received if such holder had exercised their Public Warrants immediately prior to such event. However, if such holders were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets for which each Public Warrant will become exercisable will be deemed to be the weighted average of the kind and amount received per share by such holders in such consolidation or merger that affirmatively make such election, and if a tender, exchange or redemption offer has been made to and accepted by such holders (other than a tender, exchange or redemption offer made by us in connection with redemption rights held by our stockholders or as a result of the repurchase of shares of Common Stock by us if a proposed initial business combination is presented to our stockholders for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor rule)) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act (or any successor rule)) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 50% of the outstanding shares of Common Stock, the holder of a Public Warrant will be entitled to receive the highest amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such warrant holder had exercised the Public Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from

TABLE OF CONTENTS

and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in the Warrant Agreement. Additionally, if less than 70% of the consideration receivable by the holders of Common Stock in such a transaction is payable in the form of Common Stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the Public Warrant properly exercises the Public Warrant within 30 days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the Warrant Agreement based on the per share consideration minus Black-Scholes Warrant Value (as defined in the Warrant Agreement) of the Public Warrant.

The Public Warrants have been issued in registered form under the Warrant Agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. You should review a copy of the Warrant Agreement, which is filed as an exhibit to the registration statement of which this prospectus forms a part, for a complete description of the terms and conditions applicable to the Public Warrants. The Warrant Agreement provides that the terms of the Public Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants.

The Public 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 or official bank check payable to us, for the number of Public Warrants being exercised. The warrant holders do not have the rights or privileges of holders of Common Stock and any voting rights until they exercise their Public Warrants and receive shares of Common Stock. After the issuance of shares of Common Stock upon exercise of the Public Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Private Placement Warrants

The Sponsor and Mr. Henry, Mr. Robins, Dr. Robins and Mr. Owusu-Kesse purchased an aggregate of 8,693,333 private placement warrants at a price of $1.50 per warrant for an aggregate purchase price of approximately $13,040,000 in a private placement. The private placement warrants (including the Common Stock issuable upon exercise of the private placement warrants) were not be transferable, assignable or salable until 30 days after the completion of the Business Combination. Otherwise, the private placement warrants have terms and provisions that are identical to those of the Warrants sold as part of the units in our IPO, including as to exercisability and exercise period.

Certain Anti-Takeover Provisions of Delaware Law, the Certificate of Incorporation and the Bylaws

Provisions of the DGCL and the Certificate of Incorporation could make it more difficult to acquire our company by means of a tender offer, a proxy contest or otherwise, or to remove incumbent officers and directors. These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of our company to first negotiate with the Board. We believe that the benefits of these provisions outweigh the disadvantages of discouraging certain takeover or acquisition proposals because, among other things, negotiation of these proposals could result in an improvement of their terms and enhance the ability of our Board to maximize stockholder value. However, these provisions may delay, deter or prevent a merger or acquisition of us that a stockholder might consider is in its best interest, including those attempts that might result in a premium over the prevailing market price of the Common Stock.

TABLE OF CONTENTS

In addition, the Certificate of Incorporation provides for certain other provisions that may have an anti-takeover effect:

•

There is no cumulative voting with respect to the election of directors.

•

Our Board is empowered to elect a director to fill a vacancy created by the expansion of the Board or the resignation, death, or removal of a director in certain circumstances.

•

Directors may only be removed from the Board for cause.

•

Our Board is classified into three classes of directors. As a result, in most circumstances, a person can gain control of our Board by successfully engaging in a proxy contest at two or more annual meetings.

•

A prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders.

•

A prohibition on stockholders calling a special meeting and the requirement that a meeting of stockholders may only be called by members of our Board, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors.

•

Our authorized but unissued Common Stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. Our Board is entitled, without further stockholder approval, to designate one or more series of preferred stock and the associated voting rights, preferences and privileges of such series of preferred stock. The existence of authorized but unissued and unreserved Common Stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Forum Selection Clause

The Certificate of Incorporation includes a forum selection clause, which provides that, subject to limited exceptions, the Court of Chancery of the State of Delaware and federal court within the State of Delaware will be exclusive forums for any:

•

derivative action or proceeding brought on our behalf;

•

action asserting a claim of breach of a fiduciary duty owed by, or other wrongdoing by, any director, officer, stockholder, employee or agent of us to us or our stockholders;

•

action asserting a claim against us or any director, officer, stockholder, employee or agent of us arising pursuant to any provision of the DGCL, our charter or Bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware:

•

action to interpret, apply, enforce or determine the validity of our charter or Bylaws; or

•

other action asserting a claim against us or any director, officer, stockholder, employee or agent of us that is governed by the internal affairs doctrine.

This choice of forum provision does not apply to actions brought to enforce a duty or liability created by the Exchange Act or any other claim for which federal courts have exclusive jurisdiction. Furthermore, in accordance with the Bylaws, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States will be, to the fullest extent permitted by law, the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. We intend for this provision to apply to any complaints asserting a cause of action under the Securities Act despite the fact that Section 22 of the Securities Act creates concurrent jurisdiction for the federal and state courts over all actions brought to enforce any duty or liability created by the Securities Act or the rules and regulations promulgated thereunder.

Rule 144 and Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

In general, Rule 144 of the Securities Act (Rule 144), permits the resale of restricted securities without registration under the Securities Act if certain conditions are met. Rule 144 is not available for the resale of restricted securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company, including us. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met at the time of such resale:

•

the issuer of the securities that was formerly a shell company has ceased to be a shell company;

•

the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

•

the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports; and

•

at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

We are no longer a shell company, and as long as the conditions set forth in the exceptions listed above are satisfied, Rule 144 is available for the resale of our restricted securities.

If the above conditions have been met and Rule 144 is available, a person who has beneficially owned restricted shares of our Common Stock or warrants for at least one year would be entitled to sell their securities pursuant to Rule 144, provided that such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale. If such persons are our affiliates at the time of, or at any time during the three months preceding, a sale, such persons would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

•

1% of the total number of shares of Common Stock or warrants, as applicable, then outstanding; or

•

the average weekly reported trading volume of the Common Stock or warrants, as applicable, during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by affiliates under Rule 144, when available, will also limited by manner of sale provisions and notice requirements.

As of December 31, 2022, we had 488,549,210 shares of Common Stock outstanding, all of which are freely tradable without restriction or further registration under the Securities Act, except for any shares held by our affiliates. All of the 8,959,372 Founder Shares owned by our Initial Stockholders are restricted securities under Rule 144, in that they were issued in private transactions not involving a public offering. The shares of our Common Stock we issued to the PIPE Investors pursuant to the Subscription Agreements are restricted securities for purposes of Rule 144 but we have registered the resale of such shares by the PIPE Investors.

As of the date of this prospectus, there are 19,733,290 Warrants outstanding, consisting of 11,039,957 Public Warrants originally sold as part of the units issued in our IPO and 8,693,333 private placement warrants that we sold to the Sponsor in a private sale concurrently with our IPO. Each warrant is exercisable for one share of our Common Stock, in accordance with the terms of the Warrant Agreement governing the warrants. The Public Warrants and are freely tradable, except for any warrants purchased by one of our affiliates within the meaning of Rule 144 under the Securities Act. In addition, we filed the Prior Registration Statement covering the 11,039,957 shares of our Common Stock that may be issued upon the exercise of the Public Warrants and agreed to maintain the effectiveness of such registration statement until the expiration of the warrants.

We expect Rule 144 to be available for the resale of the above noted restricted securities as long as the conditions set forth in the exceptions listed above are satisfied following the Business Combination.

Registration Rights

CMLS Registration Rights

The holders of the Founder Shares, private placement warrants (and any shares of Common Stock issuable upon the exercise of the private placement warrants), and securities that may be issued upon conversion of working capital loans are entitled to registration rights pursuant to the Amended and Restated Registration Rights Agreement. The holders of the majority of these securities are entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a business combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the Amended and Restated Registration Rights Agreement provides that we will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period. We will bear the expenses incurred in connection with the filing of any such registration statements.

Demand Registration Rights

Following the expiration of the Founder Shares Lock-Up Period, the Private Placement Lock-Up Period the Initial Sponsor Shares Lock-Up Period, the Final Sponsor Shares Lock-Up Period (each as defined in that certain Amendment to Sponsor Letter dated as of August 5, 2021) or any other applicable lock-up period, holders of at least a majority in interest of the then-outstanding number of registrable securities held by the holders or any holder expecting to sell registrable securities yielding aggregate gross proceeds in excess of $50,000,000 may make a written demand for registration of all or part of their registrable securities. We will within five days of our receipt of the demand, notify, in writing all other holders of registrable securities of such demand. Each holder who will want to participate in the registration will notify us, in writing, within five days after the receipt by the holder of the notice from us. Upon receipt by us of any such written notification from a holder(s) to us such holder(s) will be entitled to have their registrable securities included in a registration more than 60 days immediately after our receipt of the demand.

Under no circumstances will we be obligated to effect more than an aggregate of three registrations pursuant to a demand by the existing holders and an aggregate of five registrations pursuant to a demand by the new holders with respect to any or all registrable securities.

Notwithstanding the foregoing, (i) we shall not be required to give effect to a demand from a holder if we have registered registrable securities pursuant to a demand (which has become effective) from such holder in the preceding 120 days, and (ii) our obligations with respect to any demand will be deemed satisfied so long as the registration statement filed includes all of such holder’s registrable securities and is effective.

Piggyback Registration Rights

If we propose to file a registration statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for our own account or for the account of our stockholders, other than a registration statement (a) filed in connection with any employee stock option or other benefit plan, (b) for an exchange offer or offering of securities solely to our existing stockholders, (c) for an offering solely of debt that is convertible into equity securities of us, (d) for a dividend reinvestment plan, (e) for any issuances of securities in connection with a transaction involving a merger, consolidation, sale, exchange, issuance, transfer, reorganization or other extraordinary transaction between us or any of our Affiliates and any third party, or (f) filed pursuant to subsection 2.1.1 of the Amended and Restated Registration Rights Agreement, then, we need to notify the holders of registrable securities (excluding the Sponsor with respect to any Registrable Securities distributed by the Sponsor to its members following the expiration of the Initial Sponsor Shares Lock-Up Period, the Final Sponsor Shares Lock-up Period or the Private Placement Lock-up Period, as applicable) as soon as practicable but not less than 20 days before the anticipated filing date of such registration statement. This notice will offer holders of registrable securities the opportunity to register the sale of registrable securities.

TABLE OF CONTENTS

We agreed, in good faith, to cause such registrable securities identified to be included and shall use commercially reasonable efforts to cause the managing underwriter or underwriters of a proposed underwritten offering, if any, to permit the registrable securities so requested to be included on the same terms and conditions as any similar securities of us or stockholder(s) for whose account the registration statement is to be filed and to permit the sale or other disposition of such registrable securities in accordance with the intended method(s) of distribution thereof. All such holders proposing to distribute their registrable securities through an underwritten offering will enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwritten offering by us.

Shelf Registration Rights

We filed a registration statement under the Securities Act to permit the public resale of all the registrable securities held by the holders from time to time as permitted by Rule 415 under the Securities Act on the terms and conditions specified in the Amended and Restated Registration Rights Agreement and filed, within 30 days of such time as Form S-3 was available for the registration, this post-effective amendment to the registration statement then in effect, , registering the registrable securities for resale on Form S-3.

We will use our commercially reasonable efforts to cause the registration statement to remain effective, and to be supplemented and amended to the extent necessary to ensure that the registration statement is available or, if not available, that another registration statement is available at all times, for the public resale of all the registrable securities held by the holders until all such registrable securities have ceased to be registrable securities.

PIPE Subscription Agreement

Under the terms of the Subscription Agreements, we filed with the SEC (at our sole cost and expense) a registration statement registering the resale of the PIPE Shares, and we will use our commercially reasonable efforts to maintain the continuous effectiveness of the registration statement until all such securities cease to be registrable securities or such shorter period upon which each undersigned party with registrable securities included in such registration statement have notified us that such registrable securities have actually been sold.

We agreed to provide all customary and commercially reasonable cooperation necessary to enable the holders to resell registrable securities pursuant to the registration statement or Rule 144 under the Securities Act (Rule 144), as applicable, qualify the registrable securities for listing on the primary stock exchange on which our Shares are then listed, update or amend the registration statement as necessary to include registrable securities and provide customary notice to holders of registrable securities.

Public Warrants

Under the terms of the Warrant Agreement pursuant to which the Public Warrants were issued, we filed with the SEC a registration statement for the registration under the Securities Act of the shares of Common Stock issuable upon exercise of the Warrants. We agreed to use our best efforts to maintain a current prospectus relating to the Common Stock issuable upon exercise of the Public Warrants, until the expiration of the Public Warrants in accordance with the provisions of the Warrant Agreement. During any period when we failed to have maintained an effective registration statement covering the issuance of the shares of Common Stock issuable upon exercise of the Warrants, holders of the Warrants may exercise such warrants on a “cashless basis” in accordance with the provisions of the Warrant Agreement.

If the Common Stock is at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, we may, at our option, (i) require holders of Public Warrants who exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and (ii) in the event we so elect, we shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the shares of Common Stock issuable upon exercise of the Warrants, notwithstanding anything in the Warrant Agreement to the contrary, and (y) use our commercially reasonable efforts to register or qualify for sale the shares of Common Stock issuable upon exercise of the Public Warrants under applicable blue sky laws to the extent an exemption is not available.

TABLE OF CONTENTS

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a discussion of certain material U.S. federal income tax consequences of the acquisition, ownership and disposition of our shares of Common Stock, which we refer to as our securities. This discussion applies only to securities that are held as capital assets for U.S. federal income tax purposes and is applicable only to holders who are receiving our securities in this offering.

This discussion is a summary only and does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including but not limited to the alternative minimum tax, the Medicare tax on certain investment income and the different consequences that may apply if you are subject to special rules that apply to certain types of investors (such as the effects of Section 451 of the Code), including but not limited to:

•

financial institutions or financial services entities;

•

broker-dealers;

•

governments or agencies or instrumentalities thereof;

•

regulated investment companies;

•

real estate investment trusts;

•

expatriates or former long-term residents of the United States;

•

persons that actually or constructively own five percent or more of our voting shares;

•

insurance companies;

•

dealers or traders subject to a mark-to-market method of accounting with respect to the securities;

•

persons holding the securities as part of a “straddle,” hedge, integrated transaction or similar transaction;

•

U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

•

partnerships or other pass-through entities for U.S. federal income tax purposes and any beneficial owners of such entities; and

•

tax-exempt entities.

This discussion is based on the Code, and administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations as of the date hereof, which are subject to change, possibly on a retroactive basis, and changes to any of which subsequent to the date of this prospectus may affect the tax consequences described herein. This discussion does not address any aspect of state, local or non-U.S. taxation, or any U.S. federal taxes other than income taxes (such as gift and estate taxes).

We have not sought, and will not seek, a ruling from the IRS as to any U.S. federal income tax consequence described herein. The IRS may disagree with the discussion herein, and its determination may be upheld by a court. Moreover, there can be no assurance that future legislation, regulations, administrative rulings or court decisions will not adversely affect the accuracy of the statements in this discussion. You are urged to consult your tax advisor with respect to the application of U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or foreign jurisdiction.

This discussion does not consider the tax treatment of partnerships or other pass-through entities or persons who hold our securities through such entities. If a partnership (or other entity or arrangement classified as a partnership or other pass-through entity for United States federal income tax purposes) is the beneficial owner of our securities, the United States federal income tax treatment of a partner or member in the partnership or other pass-through entity generally will depend on the status of the partner or member and the activities of the partnership or other pass-through entity. If you are a partner or member of a partnership or other pass-through entity holding our securities, we urge you to consult your own tax advisor.

TABLE OF CONTENTS

THIS DISCUSSION IS ONLY A SUMMARY OF CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR SECURITIES. EACH PROSPECTIVE INVESTOR IN OUR SECURITIES IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH INVESTOR OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR SECURITIES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY UNITED STATES FEDERAL NON-INCOME, STATE, LOCAL, AND NON-U.S. TAX LAWS.

U.S. Holders

This section applies to you if you are a “U.S. holder.” A U.S. holder is a beneficial owner of our shares of Common Stock who or that is, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity taxable as a corporation) organized in or under the laws of the United States, any state thereof or the District of Columbia; or

•

an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or

•

a trust, if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons (as defined in the Code) have authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under Treasury Regulations to be treated as a U.S. person.

Taxation of Distributions. If we pay distributions in cash or other property (other than certain distributions of our stock or rights to acquire our stock) to U.S. holders of shares of our Common Stock, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. holder’s adjusted tax basis in our Common Stock. Any remaining excess will be treated as gain realized on the sale or other disposition of the Common Stock and will be treated as described under “— U.S. Holders — Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock” below.

Dividends we pay to a U.S. holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), and provided certain holding period requirements are met, dividends we pay to a non-corporate U.S. holder may constitute “qualified dividends” that will be subject to tax at the tax rate accorded to long-term capital gains. If the holding period requirements are not satisfied, then a corporation may not be able to qualify for the dividends received deduction and would have taxable income equal to the entire dividend amount, and non-corporate holders may be subject to tax on such dividend at regular ordinary income tax rates instead of the preferential rate that applies to qualified dividend income.

Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock. Upon a sale or other taxable disposition of our Common Stock, a U.S. holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. holder’s adjusted tax basis in the Common Stock. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period for the Common Stock so disposed of exceeds one year. If the holding period requirements are not satisfied, any gain on a sale or taxable disposition of the shares would generally be subject to short-term capital gain treatment and would be taxed at regular ordinary income tax rates. Long-term capital gains recognized by non-corporate U.S. holders will be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

Generally, the amount of gain or loss recognized by a U.S. holder is an amount equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such disposition and (ii) the U.S. holder’s adjusted tax basis in its Common Stock so disposed of. A U.S. holder’s adjusted tax basis in its Common Stock generally will equal the U.S. holder’s acquisition cost for

TABLE OF CONTENTS

the Common Stock reduced by any prior distributions with respect to such Common Stock that were treated as a return of capital. In the case of any shares of Common Stock originally acquired as part of an investment unit, the acquisition cost for the share of Common Stock that were part of such unit would equal an allocable portion of the acquisition cost of the unit based on the relative fair market values of the components of the unit at the time of acquisition.

Information Reporting and Backup Withholding. In general, information reporting requirements may apply to dividends paid to a U.S. holder and to the proceeds of the sale or other disposition of our shares of Common Stock, unless the U.S. holder is an exempt recipient. Backup withholding may apply to such payments if the U.S. holder fails to provide a taxpayer identification number, a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Any amounts withheld under the backup withholding rules generally should be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Non-U.S. Holders

This section applies to you if you are a “Non-U.S. holder.” As used herein, the term “Non-U.S. holder” means a beneficial owner of our Common Stock who or that is for U.S. federal income tax purposes:

•

a non-resident alien individual (other than certain former citizens and residents of the U.S. subject to U.S. tax as expatriates);

•

a foreign corporation; or

•

an estate or trust that is not a U.S. holder;

but generally does not include an individual who is present in the U.S. for 183 days or more in the taxable year of disposition. If you are such an individual, you should consult your tax advisor regarding the U.S. federal income tax consequences of the acquisition, ownership or sale or other disposition of our securities.

Taxation of Distributions. In general, any distributions we make to a Non-U.S. holder of shares of our Common Stock, to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute dividends for U.S. federal income tax purposes and, provided such dividends are not effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States, we will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such Non-U.S. holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E). Any distribution not constituting a dividend will be treated first as reducing (but not below zero) the Non-U.S. holder’s adjusted tax basis in its shares of our Common Stock and, to the extent such distribution exceeds the Non-U.S. holder’s adjusted tax basis, as gain realized from the sale or other disposition of the Common Stock, which will be treated as described under “Non-U.S. Holders — Gain on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock” below.

The withholding tax does not apply to dividends paid to a Non-U.S. holder who provides a Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the Non-U.S. holder were a U.S. resident, subject to an applicable income tax treaty providing otherwise. A Non-U.S. corporation receiving effectively connected dividends may also be subject to an additional “branch profits tax” imposed at a rate of 30% (or a lower treaty rate).

Gain on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock. A Non-U.S. holder generally will not be subject to U.S. federal income or withholding tax in respect of gain recognized on a sale, taxable exchange or other taxable disposition of our Common Stock, unless:

TABLE OF CONTENTS

•

the gain is effectively connected with the conduct of a trade or business by the Non-U.S. holder within the United States (and, under certain income tax treaties, is attributable to a United States permanent establishment or fixed base maintained by the Non-U.S. holder); or

•

we are or have been a “U.S. real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the Non-U.S. holder held our Common Stock, and, in the case where shares of our Common Stock are regularly traded on an established securities market, the Non-U.S. holder has owned, directly or constructively, more than 5% of our Common Stock at any time within the shorter of the five-year period preceding the disposition or such Non-U.S. holder’s holding period for the shares of our Common Stock. There can be no assurance that our Common Stock will be treated as regularly traded on an established securities market for this purpose.

Unless an applicable treaty provides otherwise, gain described in the first bullet point above will be subject to tax at generally applicable U.S. federal income tax rates as if the Non-U.S. holder were a U.S. resident. Any gains described in the first bullet point above of a Non-U.S. holder that is a foreign corporation may also be subject to an additional “branch profits tax” at a 30% rate (or lower treaty rate).

If the second bullet point above applies to a Non-U.S. holder, gain recognized by such holder on the sale, exchange or other disposition of our Common Stock will be subject to tax at generally applicable U.S. federal income tax rates.

Information Reporting and Backup Withholding. Information returns will be filed with the IRS in connection with payments of dividends and the proceeds from a sale or other disposition of our shares of Common Stock. A Non-U.S. holder may have to comply with certification procedures to establish that it is not a United States person in order to avoid information reporting and backup withholding requirements. The certification procedures required to claim a reduced rate of withholding under a treaty will satisfy the certification requirements necessary to avoid the backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. holder will be allowed as a credit against such holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA Withholding Taxes. Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of dividends (including constructive dividends) on our Common Stock to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other Non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied by, or an exemption applies to, the payee (typically certified as to by the delivery of a properly completed IRS Form W-8BEN-E). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Under certain circumstances, a Non-U.S. holder might be eligible for refunds or credits of such withholding taxes, and a Non-U.S. holder might be required to file a U.S. federal income tax return to claim such refunds or credits. Prospective investors should consult their tax advisers regarding the effects of FATCA on their investment in our securities.

PLAN OF DISTRIBUTION

We are registering the issuance by us of (i) up to 8,693,333 shares of Common Stock that are issuable upon the exercise of the Placement Warrants by the holders thereof and (ii) up to 11,040,000 shares of Common Stock that are issuable upon the exercise of the Public Warrants by the holders thereof. We are also registering the resale by the Selling Securityholders or their permitted transferees from time to time of (i) up to 340,919,633 shares of Common Stock and (ii) up to 8,693,333 Placement Warrants.

We are required to pay all fees and expenses incident to the registration of the securities to be offered and sold pursuant to this prospectus. The Selling Securityholders will bear all commissions and discounts, if any, attributable to their sale of securities.

We will not receive any of the proceeds from the sale of the securities by the Selling Securityholders. We will receive proceeds from Warrants exercised in the event that such Warrants are exercised for cash. The aggregate proceeds to the Selling Securityholders will be the purchase price of the securities less any discounts and commissions borne by the Selling Securityholders.

The shares of Common Stock owned by the Selling Securityholders covered by this prospectus may be offered and sold from time to time by the Selling Securityholders. The term “Selling Securityholders” includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from a Selling Securityholder as a gift, pledge, partnership distribution or other transfer. The Selling Securityholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. The Selling Securityholders may sell their securities by one or more of, or a combination of, the following methods:

•

purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

•

ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•

block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

an over-the-counter distribution in accordance with the rules of Nasdaq;

•

through trading plans entered into by a Selling Securityholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

•

short sales;

•

distribution to employees, members, limited partners or stockholders of the Selling Securityholders; through the writing or settlement of options or other hedging transaction, whether through an options exchange or otherwise;

•

by pledge to secured debts and other obligations;

•

delayed delivery arrangements;

•

to or through underwriters or broker-dealers;

•

in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

•

in privately negotiated transactions;

•

in options transactions;

TABLE OF CONTENTS

•

through a combination of any of the above methods of sale; or

•

any other method permitted pursuant to applicable law.

In addition, any securities that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the securities or otherwise, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of the securities in the course of hedging the positions they assume with Selling Securityholders. The Selling Securityholders may also sell the securities short and redeliver the securities to close out such short positions. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The Selling Securityholders may also pledge securities to a broker-dealer or other financial institution, and, upon a default, such broker- dealer or other financial institution, may effect sales of the pledged securities pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In effecting sales, broker-dealers or agents engaged by the Selling Securityholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Securityholders in amounts to be negotiated immediately prior to the sale.

In offering the securities covered by this prospectus, the Selling Securityholders and any broker-dealers who execute sales for the Selling Securityholders may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. Any profits realized by the Selling Securityholders and the compensation of any broker-dealer may be deemed to be underwriting discounts and commissions.

In order to comply with the securities laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We have advised the Selling Securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of securities in the market and to the activities of the Selling Securityholders and their affiliates. In addition, we will make copies of this prospectus available to the Selling Securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the securities against certain liabilities, including liabilities arising under the Securities Act.

At the time a particular offer of securities is made, if required, a prospectus supplement will be distributed that will set forth the number of securities being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

A holder of Warrants may exercise its Warrants in accordance with the Warrant Agreement on or before the expiration date set forth therein by surrendering, at the office of the warrant agent, Continental Stock Transfer & Trust Company, the certificate evidencing such Warrant, with the form of election to purchase set forth thereon, properly completed and duly executed, accompanied by full payment of the exercise price and any and all applicable taxes due in connection with the exercise of the Warrant, subject to any applicable provisions relating to cashless exercises in accordance with the Warrant Agreement.

A Selling Securityholder that is an entity may elect to make an in-kind distribution of Common Stock or Warrants to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus. To the extent that such members, partners or stockholders

TABLE OF CONTENTS

are not affiliates of ours, such members, partners or stockholders would thereby receive freely tradable Common Stock or Warrants pursuant to the distribution through a registration statement.

Item 15. Indemnification of Directors and Officers.

Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), because he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if he or she 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, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if he or she 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, except that no indemnification shall be made with respect to any claim, issue or matter as to which he or she 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, he or she is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or other adjudicating court shall deem proper.

Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

Additionally, the Certificate of Incorporation, which became effective upon completion of the Business Combination, provides that no director of ours shall be personally liable to us or our stockholders for

II-1

TABLE OF CONTENTS

monetary damages for any breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to us or our stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) in respect of unlawful dividend payments or stock redemptions or repurchases, or (4) for any transaction from which the director derived an improper personal benefit. In addition, the Certificate of Incorporation provides that if the DGCL is amended to authorize the further elimination or limitation of the liability of directors, then the liability of a director of ours shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

The Certificate of Incorporation further provides that any repeal or modification of such article by its stockholders or amendment to the DGCL will not adversely affect any right or protection existing at the time of such repeal or modification with respect to any acts or omissions occurring before such repeal or modification of a director serving at the time of such repeal or modification.

The Bylaws provide that we will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by us or in our right) by reason of the fact that he or she is or was, or has agreed to become, our director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture or other enterprise (all such persons being referred to as an Indemnitee), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. The Bylaws also provide that we will advance expenses to Indemnitees in connection with a legal proceeding, subject to limited exceptions.

In connection with the Business Combination, we entered into indemnification agreements with each of our directors and executive officers. These agreements provide that we will indemnify each of our directors and such officers to the fullest extent permitted by law and the Certificate of Incorporation and the Bylaws.

We will also maintain a general liability insurance policy, which will cover certain liabilities of directors and officers of ours arising out of claims based on acts or omissions in their capacities as directors or officers.

Item 17. Undertakings.

(a)

The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission (the Commission) pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that: Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(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 and Exchange Act of 1934, as amended (the Exchange Act), 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.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

II-3

TABLE OF CONTENTS

(4)

That, for the purpose of determining liability under the Securities Act to any purchaser:

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof

(c)

Insofar as indemnification for liabilities arising under the Securities Act 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 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 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 and will be governed by the final adjudication of such issue.
