Up to $80,000,000

American Depositary Shares representing Ordinary Shares

 

 

We have entered into a sales agreement, or the sales agreement, with Cowen and Company LLC, or Cowen, relating to the sale of American Depositary Shares, or ADSs, representing ordinary shares. In accordance with the terms of the sales agreement, we may offer and sell ADSs having an aggregate offering price of up to $80,000,000 from time to time through Cowen acting as sales agent. Each ADS will represent seven ordinary shares and will be evidenced by American Depositary Receipts, or ADRs.

Our ADSs are listed on the New York Stock Exchange under the symbol “AMAM.” On July 28, 2022, the last reported sale price of our ADSs was $2.75 per ADS.

Sales of our securities, if any, under this prospectus may be made by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or the Securities Act. Cowen is not required to sell any specific number or dollar amount of securities, but will act as a sales agent using commercially reasonable efforts consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the New York Stock Exchange, on mutually agreed terms between Cowen and us. There are no minimum sale requirements, and there is no arrangement for funds to be received in any escrow, trust or similar arrangement.

The compensation payable to Cowen for sales of securities sold pursuant to the sales agreement will be an amount up to 3.0% of the gross proceeds of any ADSs sold under the sales agreement. See “Plan of Distribution” for additional information regarding compensation to be paid to Cowen. In connection with the sale of the ADSs on our behalf, Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Cowen will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to Cowen with respect to certain liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended, or the Exchange Act.

 

 

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risks and uncertainties described under the heading “Risk Factors” on page S-5 of this prospectus, and under similar headings in the other documents that are incorporated by reference into this prospectus.

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

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form F-3 that we filed with the U.S. Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under this shelf registration process, we may from time to time sell ADSs representing our ordinary shares having an aggregate offering price of up to $80.0 million under this prospectus at prices and on terms to be determined by market conditions at the time of the offering.

This prospectus and the documents incorporated into this prospectus by reference include important information about us, the securities being offered and other information you should know before investing in our securities. To the extent there is a conflict between the information contained in this prospectus, on the one hand, and the information contained in any document incorporated by reference into this prospectus that was filed with the SEC before the date of this prospectus, on the other hand, you should rely on the information in this prospectus. If any statement in one of these documents is inconsistent with a statement in another document having a later date (for example, a document incorporated by reference in this prospectus), the statement in the document having the later date modifies or supersedes the earlier statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus.

You should rely only on the information contained in or incorporated by reference in this prospectus and in any free writing prospectus that we authorized for use in connection with this offering. We have not, and the sales agent has not, authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and the sales agent is not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus, the documents incorporated by reference in this prospectus and in any free writing prospectus that we have authorized for use in connection with this offering, is accurate only as of the date of those respective documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should read this prospectus, any applicable prospectus supplement and any related free writing prospectus, together with the information incorporated herein by reference as described under the heading “Incorporation of Documents by Reference,” before investing in any of the securities offered.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in this prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were accurate only as of the date when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

Unless otherwise indicated or the context otherwise requires, all references in this prospectus to the terms “Ambrx,” “the company,” “we,” “us” and “our” refer to Ambrx Biopharma Inc., an exempted company incorporated in the Cayman Islands with limited liability and our wholly-owned subsidiaries.

PROSPECTUS SUMMARY

The following summary highlights information contained elsewhere in this prospectus or incorporated by reference in this prospectus, and does not contain all of the information that you need to consider in making your investment decision. We urge you to read this entire prospectus, including our consolidated financial statements, notes to the consolidated financial statements and other information incorporated by reference from our other filings with the SEC or included in the applicable prospectus supplement. Investing in our securities involves risks. Therefore, carefully consider the risks of investing in our securities discussed under the heading “Risk Factors” contained in the applicable prospectus supplement and any related free writing prospectus, and under similar headings in the other documents that are incorporated by reference into this prospectus. Each of the risk factors could adversely affect our business, operating results and financial condition, as well as the value of an investment in our securities.

Company Overview

We are a clinical-stage biologics company focused on discovering and developing a novel class of engineered precision biologics, or EPBs, using our proprietary expanded genetic code technology platform that allows us to incorporate, in a site-specific manner, synthetic amino acids, or SAAs, into proteins within living cells. Our product candidates are designed to overcome the inherent limitations of conventional conjugation approaches that use natural amino acids for non-site-specific conjugation, offering potential safety and efficacy benefits to treat patients across multiple therapeutic areas. We believe that our technology allows us to engineer a single optimized structure by designing the conjugation chemistries, selecting the precise number of amino acids and conjugation positions in the protein, and expanding the types of payloads that can be conjugated. Our precision engineering capabilities and the broad applicability of our expanded genetic code technology platform have the potential to enhance and enable the therapeutic functions of conventional biologics and bio-conjugates. Our SAA incorporation technology allows us to develop a wide array of product candidate modalities, such as antibody-drug conjugates, or ADCs, bispecific antibodies, PEGylated peptides, modified cytokines and immuno-stimulating antibody conjugates. Our most advanced internal product candidate is ARX788, an anti-HER2 ADC, currently being investigated in multiple clinical trials for the treatment of breast cancer, gastric/gastroesophageal junction cancer and other solid tumors, including ongoing Phase 2/3 clinical trials for the treatment of HER2-positive metastatic breast cancer and gastric cancer.

Our mission is to discover and develop a pipeline of EPBs to treat a broad range of diseases and disorders, with an initial focus on cancers with a high unmet medical need. We believe that combining our pioneering efforts in expanded genetic code and site-specific bio-conjugates with a team of dedicated professionals bound by a culture and vision that embraces innovation, practicality, and accountability will allow us to pursue our mission.

In the second quarter of 2022, we received verbal notification from Bristol-Myers Squibb Company, or BMS, of its intent to terminate the Collaboration and License Agreement between us and BMS dated September 21, 2011, related to the FGF21 asset, which was followed by a formal notification in July 2022. The termination will be effective three months from receipt of the formal notification date. As of June 30, 2022, we determined that the BMS FGF21 asset had no alternative future use for accounting purposes, and concluded that the net carrying value of the BMS FGF21 asset was less than its estimated fair value and therefore recorded an impairment charge of approximately $7.2 million during the second quarter of 2022.

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company”, or EGC, as defined in the U.S. Jumpstart Our Business Startups Act of 2012, or the JOBS Act. As an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include

 

   

exemption from the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002; and

 

   

to the extent that we no longer qualify as a foreign private issuer, (1) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and (2) exemptions from the requirements of holding a non-binding advisory vote on executive compensation, including golden parachute compensation.

We may take advantage of these provisions until we are no longer an emerging growth company. We will remain an EGC until the earlier to occur of (1) (a) December 31, 2026, (b) the last day of the fiscal year in which our annual gross revenue is $1.07 billion or more, or (c) the date on which we are deemed to be a “large accelerated filer,” under the rules of the SEC, which means the market value of our equity securities that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. We may choose to take advantage of some but not all of these reduced burdens. To the extent that we take advantage of these reduced burdens, the information that we provide shareholders may be different than you might obtain from other public companies in which you hold equity interests.

In addition, under the JOBS Act, EGCs can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected not to avail ourselves of delayed adoption of new or revised accounting standards and, therefore, we will be subject to the same requirements to adopt new or revised accounting standards as other public companies that are not EGCs.

Implications of Being a Foreign Private Issuer

We are also considered a “foreign private issuer” under U.S. securities laws. In our capacity as a foreign private issuer, we are exempt from certain rules under the Securities Exchange Act of 1934, or the Exchange Act, that impose certain disclosure obligations and procedural requirements for proxy solicitations under Section 14 of the Exchange Act. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of our securities. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. In addition, we are not required to comply with Regulation FD, which restricts the selective disclosure of material information.

As a foreign private issuer, we are permitted to follow certain home country corporate governance practices instead of those otherwise required under the New York Stock Exchange listing rules for domestic issuers. For instance, we follow home country practice in the Cayman Islands with regard to, among other things, board composition, director nomination procedures and quorum at shareholders’ meetings. Following our home country governance practices in lieu of the corporate governance standards that would otherwise apply to a U.S. domestic issuer listed on the New York Stock Exchange may provide less protection than is accorded to investors under the New York Stock Exchange listing rules applicable to domestic issuers.

We may take advantage of these exemptions until such time as we are no longer a foreign private issuer. We will remain a foreign private issuer until such time that more than 50% of our outstanding voting securities are held

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described below and under the heading “Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2021 as updated by our subsequent filings, some of which are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. Each of the risk factors could adversely affect our business, operating results, financial condition and cash flows, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. Please also read carefully the section below titled “Special Note Regarding Forward-Looking Statements.”

You may experience immediate and substantial dilution in the net tangible book value per ADS of your investment.

The offering price per ADS in this offering may exceed the net tangible book value per ADS outstanding prior to this offering. After giving effect to the sale of ADSs in the aggregate amount of $80.0 million at an assumed offering price of $2.75 per ADS, the last reported sale price of our ADSs on July 28, 2022 on the New York Stock Exchange, and after deducting commissions and estimated offering expenses, our as adjusted net tangible book value as of December 31, 2021 would have been $218.3 million, or $3.23 per ADS. Furthermore, you will experience additional dilution upon exercise of any outstanding options to purchase ordinary shares or ADSs, or if we otherwise issue additional ordinary shares or ADSs below the offering price. See the section titled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering. Because the sales of the securities offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these securities will vary and these variations may be significant. Purchasers of the securities we sell, as well as our existing shareholders, will experience significant dilution if we sell the securities at prices significantly below the price at which they invested.

Raising additional capital may cause dilution to our shareholders restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through equity offerings, debt financings or other capital sources, including potentially grants, collaborations, licenses or other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as an ADS holder. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as limitations on our ability to incur additional debt, make capital expenditures or declare dividends.

If we raise funds through collaborations or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We have broad discretion in the use of the net proceeds from this offering and may use them in ways with which you do not agree and in ways that may not increase the value of your investment.

Our management will have broad discretion in the application of the net proceeds that we receive from this offering. We may spend or invest these proceeds in a way with which our shareholders and ADS holders

 

S-5


disagree. The failure by our management to apply these funds effectively could harm our business and financial condition. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

Future sales or issuances of our ADSs in the public markets, or the perception of such sales, could depress the trading price of our ADSs.

The sale of a substantial number of shares of our ADSs in the public markets, or the perception that such sales could occur, could depress the market price of our ADSs and impair our ability to raise capital through the sale of additional equity securities. We may sell large quantities of our ADSs at any time pursuant to this prospectus or in one or more separate offerings. We cannot predict the effect that future sales of ADSs would have on the market price of our ADSs.

The actual number of ADSs we will issue under the sales agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a placement notice to Cowen at any time throughout the term of the sales agreement. The number of ADSs that are sold by Cowen after delivering a placement notice will fluctuate based on the market price of our ADSs during the sales period and limits we set with Cowen. Because the price per ADS of each ADS sold will fluctuate based on the market price of our ADSs during the sales period, it is not possible at this stage to predict the number of ADSs that will be ultimately issued.

The ADSs offered hereby will be sold in “at the market offerings,” and investors who buy ADSs at different times will likely pay different prices.

Investors who purchase ADSs in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of ADSs sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their ADSs as a result of ADS sales made at prices lower than the prices they paid.

Holders of our ADSs have fewer rights than our shareholders and must act through the depositary to exercise their rights.

Holders of our ADSs do not have the same rights as our shareholders and may only exercise their voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Holders of the ADSs must appoint the depositary or its nominee as their representative to exercise the voting rights attaching to the ordinary shares represented by the ADSs. When a general meeting is convened, if you hold ADSs, you may not receive sufficient notice of a shareholders’ meeting to permit you to withdraw the ordinary shares underlying your ADSs to allow you to vote with respect to any specific matter. We will take all commercially reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but we cannot assure you that you will receive voting materials in time to instruct the depositary to vote, and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote. Furthermore, the depositary will not be liable for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you request. In addition, in your capacity as an ADS holder, you will not be able to call a shareholders’ meeting.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the

 

S-6


securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless either both the rights and any related securities are registered under the Securities Act, or the distribution of them to ADS holders is exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. If the depositary does not distribute the rights, it may, under the deposit agreement, either sell them, if possible, or allow them to lapse. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

Purchasers of ADSs in the offering may be subject to limitations on the transfer of their ADSs and the withdrawal of the underlying ordinary shares.

ADSs, which may be evidenced by ADRs, are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any requirement of law, government or governmental body, or under any provision of the amended and restated deposit agreement, or for any other reason subject to a holder of ADSs’ right to cancel his or her ADSs and withdraw the underlying ordinary shares. Temporary delays in the cancellation of ADSs and withdrawal of the underlying ordinary shares may arise because the depositary has closed its transfer books or we have closed our transfer books, the transfer of ordinary shares is blocked to permit voting at a shareholders’ meeting or we are paying a dividend on our ordinary shares. In addition, a holder of ADSs may not be able to cancel his or her ADSs and withdraw the underlying ordinary shares when he or she owes money for fees, taxes and similar charges and when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities. See the section of this prospectus titled “Description of American Depositary Shares.”

These forward-looking statements involve various risks and uncertainties. Although we believe that our expectations expressed in these forward-looking statements are reasonable, our expectations may later be found to be incorrect. Our actual results could be materially different from our expectations. Important risks and factors that could cause our actual results to be materially different from our expectations are generally set forth in “Prospectus Summary,” “Risk Factors,” and other sections in this prospectus. You should read thoroughly this prospectus and the documents that we refer to with the understanding that our actual future results may be materially different from and worse than what we expect. We qualify all of our forward-looking statements by these cautionary statements.

You should read this prospectus and the documents that we refer to in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect.

 

S-9


USE OF PROCEEDS

We may issue and sell our ADSs representing our ordinary shares having aggregate sales proceeds of up to $80.0 million from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the sales agreement with Cowen as a source of financing.

We currently intend to use the net proceeds from this offering primarily to fund the research and development of our product candidates, for working capital and for general corporate purposes. We may also use a portion of the net proceeds to acquire or invest in businesses, products or technologies that we believe are complementary to our own, although we have no current plans, commitments or agreements with respect to any acquisitions as of the date of this prospectus. Pending the use of net proceeds, we intend to invest the net proceeds in short-term, investment-grade, interest bearing obligations, certificates of deposit or direct or guaranteed obligations of the United States government.

DILUTION

Our net tangible book value as of December 31, 2021 was $141.3 million, or $0.52 per ordinary share and $3.66 per ADS. Our historical net tangible book value per ordinary share is determined by dividing (1) our total assets less our intangible assets (excluding our right-of-use assets related to our leases) and our total liabilities by (2) 270,120,548 ordinary shares outstanding as of December 31, 2021.

After giving effect to the sale of our ADSs in the aggregate amount of $80.0 million at an assumed offering price of $2.75 per ADS, the last reported sale price of our ADSs on the New York Stock Exchange on July 28, 2022, and after deducting estimated commissions and offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2021 would have been $218.3 million, or $0.46 per ordinary share and $3.23 per ADS. This represents an immediate decrease in net tangible book value of $0.06 per ordinary share and $0.43 per ADS to existing shareholders and an immediate increase in net tangible book value of $0.07 per ordinary share and $0.48 per ADS to investors purchasing in this offering.

The following table illustrates this calculation on a per ADS basis. The information is illustrative only and will adjust based on the actual prices at which ADSs are sold, the actual number of ADSs sold and other terms of the offering determined at the time our ADSs are sold pursuant to this prospectus.

The number of ordinary shares (including ordinary shares in the form of ADSs) outstanding as of December 31, 2021 was 270,120,548, which excludes:

 

   

34,200,976 ordinary shares issuable upon the exercise of stock options outstanding as of December 31, 2021, at a weighted-average exercise price of $1.43 per share;

 

   

35,150,748 ordinary shares reserved for future issuance under the 2021 Plan as of December 31, 2021, as well as any annual automatic increases in the number of ordinary shares reserved for future issuance under the 2021 Plan; and

 

   

5,595,876 ordinary shares reserved for future issuance under the ESPP as of December 31, 2021, as well as any annual automatic increases in the number of ordinary shares reserved for issuance under the ESPP.

The ADSs subject to the sales agreement with Cowen will be sold from time to time at various prices. An increase of $1.00 per ADS in the price at which the ADSs are sold from the assumed offering price of $2.75 per ADS shown in the table above, assuming all of our securities in the aggregate amount of $80.0 million during the term of the sales agreement with Cowen are sold at that price, would increase our as adjusted net tangible book value per ADS after the offering to $0.52 per ordinary share and $3.64 per ADS, which would represent a decrease in net tangible book value per ADS to new investors in this offering of $0.02 per ordinary share and $0.11 per ADS, after deducting commissions and estimated offering expenses payable by us. A decrease of $1.00 per ADS in the price at which the ADSs are sold from the assumed offering price of $2.75 per ADS shown in the table above, assuming all of our securities in the aggregate amount of $80.0 million during the term of the sales agreement with Cowen are sold at that price, would decrease our as adjusted net tangible book value per ADS after the offering to $0.37 per ordinary share and $2.59 per ADS, which would represent an increase in net

tangible book value per ADS to new investors in this offering of $0.12 per ordinary share and $0.84 per ADS, after deducting commissions and estimated offering expenses payable by us. This information is supplied for illustrative purposes only.

To the extent that options outstanding as of December 31, 2021 have been or may be exercised or other shares issued, investors purchasing our ADSs in this offering may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our investors.

MATERIAL UNITED STATES FEDERAL INCOME TAX AND CAYMAN ISLANDS TAX CONSIDERATIONS

The following describes material U.S. federal income tax and Cayman Islands tax considerations relating to the acquisition, ownership and disposition of ADSs by a U.S. holder (as defined below). This summary does not address all U.S. federal income tax and Cayman Islands tax matters that may be relevant to a particular U.S. holder. This summary does not address tax considerations applicable to a holder of ADSs that may be subject to special tax rules including, without limitation, the following:

 

   

banks, financial institutions or insurance companies;

 

   

brokers, dealers or traders in securities, currencies, commodities, or notional principal contracts;

 

   

tax-exempt entities or organizations, including an “individual retirement account” or “Roth IRA” as defined in Section 408 or 408A of the Code (as defined below), respectively;

 

   

real estate investment trusts, regulated investment companies or grantor trusts;

 

   

persons that hold the ADSs as part of a “hedging,” “integrated,” “wash sale” or “conversion” transaction or as a position in a “straddle” for U.S. federal income tax purposes;

 

   

S corporations;

 

   

persons acquiring ADSs in connection with a trade or business conducted outside of the United States;

 

   

persons subject to Section 451(b) of the Code;

 

   

holders that own directly, indirectly, or through attribution 10% or more of the voting power or value of our ADSs and shares; and

 

   

holders that have a “functional currency” other than the U.S. dollar.

For the purposes of this description, a “U.S. holder” is a beneficial owner of ADSs that is (or is treated as), for U.S. federal income tax purposes:

 

   

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

 

   

a domestic corporation;

 

   

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

 

   

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

If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds ADSs, the U.S. federal income tax consequences relating to an investment in the ADSs will depend in part upon the status of the partner and the activities of the partnership. Such a partner or partnership should consult its tax advisor regarding the U.S. federal income tax considerations of acquiring, owning and disposing of the ADSs in its particular circumstances.

The discussion in this section is based in part upon the representations of the depositary and the assumption that each obligation in the amended and restated deposit agreement and any related agreement will be performed in accordance with its terms.

Persons considering an investment in the ADSs should consult their own tax advisors as to the particular tax consequences applicable to them relating to the acquisition, ownership and disposition of the ADSs, including the applicability of U.S. federal, state and local tax laws, Cayman Islands tax laws and other non-U.S. tax laws.

Material Cayman Islands Tax Considerations

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty.

There are no other taxes are likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution, brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties which are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of our ordinary shares and ADSs will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of dividends or capital to any holder of our ordinary shares or ADSs, nor will gains derived from the disposal of our ordinary shares or ADSs be subject to Cayman Islands income or corporation tax.

Pursuant to section 6 of the Tax Concessions Act (As Revised) of the Cayman Islands, the Company has obtained an undertaking from the Governor-in-Cabinet:

(i) that no law which is enacted in the Cayman Islands imposing any tax to be levied on profit or income or gains or appreciations shall apply to the Company or its operations; and

(ii) in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable by the Company:

 

   

on or in respect of the shares, debenture, or other obligations of the Company; or

 

   

by way of withholding in whole or in part of any relevant payment as defined in section 6(3) of the Tax Concessions Act (As Revised).

These concessions shall be for a period of 20 years from 26 May 2015.

Material U.S. Federal Income Tax Considerations

This section discusses the material U.S. federal income tax considerations relating to the acquisition, ownership and disposition of ADSs by a U.S. holder who acquires its ADSs pursuant to this offering and holds the ADSs as a capital asset. This description does not address the U.S. federal estate, gift, or alternative minimum tax considerations, or any U.S. state, local, or non-U.S. tax considerations of the acquisition, ownership and disposition of the ADSs.

This description is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, existing, proposed and temporary U.S. Treasury Regulations promulgated thereunder and administrative and judicial interpretations thereof, in each case as in effect and available on the date hereof. All the foregoing is subject to change, which change could apply retroactively, and to differing interpretations, all of which could affect the tax considerations described below. There can be no assurances that the U.S. Internal Revenue Service, or the IRS, will not take a position different from what is described below concerning the tax consequences of the acquisition, ownership and disposition of the ADSs or that such a position would not be sustained by a court. U.S. holders should consult their own tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of the ADSs in their particular circumstances.

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, a U.S. holder holding ADRs evidencing ADSs will be treated as the owner of the shares presented by the ADRs. Exchanges of shares for ADRs, and ADRs for shares, generally will not be subject to U.S. federal income tax.

Passive Foreign Investment Company Considerations. Based on the composition of our gross income, assets, activities and market capitalization in 2021, the nature of our business and due to fluctuations in our stock price,

 

S-14


we believe that we were not characterized as a PFIC for our taxable year ending December 31, 2021 and do not anticipate being a PFIC for our current taxable year or the foreseeable future. Because the calculation of the value of our assets may be based in part on the value of our ADSs, the value of which may fluctuate considerably, our PFIC status may change from year to year and is difficult to predict. There can be no assurance that we will not be considered a PFIC for the current year or any future taxable year. A separate determination must be made after the close of each taxable year as to whether we are a PFIC for that year. As a result, our PFIC status may change from year to year and we have not yet made any determination as to our expected PFIC status for the current year. Our U.S. counsel expresses no opinion regarding our conclusions or our expectations regarding our PFIC status.

If we are classified as a PFIC, a U.S. holder will be subject to special rules discussed below. If we are classified as a PFIC in any year with respect to which a U.S. holder owns the ADSs, we will continue to be treated as a PFIC with respect to the ADSs and such U.S. holder in all succeeding years during which the U.S. holder owns the ADSs, regardless of whether we continue to meet the PFIC tests described below.

We will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules with respect to the income and assets of our subsidiaries, either: (i) at least 75% of the gross income is “passive income” or (ii) at least 50% of the average quarterly value of our total gross assets (which would generally be measured by fair market value of our assets, and for which purpose the total value of our assets may be determined in part by the market value of the ADSs and our ordinary shares, which are subject to change) is attributable to assets that produce “passive income” or are held for the production of “passive income.”

Passive income for this purpose generally includes dividends, allocations of income with respect to any partnership interest, interest, royalties, rents, gains from commodities and securities transactions, the excess of gains over losses from the disposition of assets which produce passive income, and includes amounts derived by reason of the temporary investment of funds raised in offerings of the ADSs. If a non-U.S. corporation owns directly or indirectly at least 25% by value of the stock of another corporation or the partnership interests in a partnership, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation or partnership and as receiving directly its proportionate share of the other corporation’s or partnership’s income.

The market value of our assets may be determined in large part by reference to the market price of the ADSs and our ordinary shares, which is likely to fluctuate. In addition, the composition of our income and assets will be affected by how, and how quickly, we use the cash proceeds from this offering in our business. Whether we are a PFIC for any taxable year will depend on our assets and income (including whether we receive certain non-refundable grants or subsidies and whether such amounts and reimbursements of certain refundable research tax credits will constitute gross income for purposes of the PFIC income test) in each year, and because this is a factual determination made annually after the end of each taxable year, there can be no assurance that we will not be considered a PFIC in any taxable year.

If we are a PFIC, and you are a U.S. holder that does not make one of the elections described below, a special tax regime will apply to both (a) any “excess distribution” by us to you (generally, your ratable portion of distributions in any year which are greater than 125% of the average annual distribution received by you in the shorter of the three preceding years or your holding period for the ADSs) and (b) any gain realized on the sale or other disposition of the ADSs. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (i) the excess distribution or gain had been realized ratably over your holding period, (ii) the amount deemed realized in each year had been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any taxable period before we became a PFIC, which would be subject to tax at the U.S. holder’s regular ordinary income rate for the current year and would not be subject to the interest charge discussed below), and (iii) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been

 

S-15


payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to qualified dividends discussed above under “Distributions.”

Certain elections may alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment of the ADSs. If a U.S. holder makes a mark-to-market election, the U.S. holder generally will recognize as ordinary income any excess of the fair market value of the ADSs at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. holder makes the election, the U.S. holder’s tax basis in the ADSs will be adjusted to reflect these income or loss amounts. Any gain recognized on the sale or other disposition of ADSs in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). The mark-to-market election is available only if we are a PFIC and the ADSs are “regularly traded” on a “qualified exchange.” The ADSs will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the ADSs are traded on a qualified exchange on at least 15 days during each calendar quarter (subject to the rule that trades that have as one of their principal purposes the meeting of the trading requirement as disregarded). The New York Stock Exchange is a qualified exchange for this purpose and, consequently, if the ADSs are regularly traded, the mark-to-market election will be available to a U.S. holder.

If we are a PFIC, we expect to provide investors, upon request, a “PFIC Annual Information Statement” with the information required to allow investors to make a “qualified electing fund election” or “QEF Election” for United States federal income tax purposes. U.S. holders should consult their tax advisors to determine whether any of these elections would be available and if so, what the consequences of the alternative treatments would be in their particular circumstances.

If a U.S. holder makes a QEF Election with respect to a PFIC, in lieu of the tax consequences described below, the U.S. holder will be subject to current taxation on its pro rata share of the PFIC’s ordinary earnings and net capital gain for each taxable year that the entity is classified as a PFIC. If a U.S. holder makes a QEF Election with respect to us, any distributions paid by us out of our earnings and profits that were previously included in the U.S. holder’s income under the QEF Election will not be taxable to the holder. A U.S. holder will increase its tax basis in its ADSs by an amount equal to any income included under the QEF Election and will decrease its tax basis by any amount distributed on the ADSs that is not included in the holder’s income. In addition, a U.S. holder will recognize capital gain or loss on the disposition of ADSs in an amount equal to the difference between the amount realized and the holder’s adjusted tax basis in the ADSs. U.S. holders should note that if they make QEF Elections with respect to us and lower-tier PFICs, they may be required to pay U.S. federal income tax with respect to their ADSs for any taxable year significantly in excess of any cash distributions (which are expected to be zero) received on the ADSs for such taxable year. U.S. holders should consult their tax advisors regarding making QEF Elections in their particular circumstances. If a U.S. holder does not make and maintains a QEF election for the U.S. holder’s entire holding period for our ADSs by making the election for the first year in which the U.S. holder owns our ADSs pursuant to this offering, the U.S. holder will be subject to the adverse PFIC rules discussed above unless the U.S. holder can properly make a “purging election” with respect to our ADSs in connection with the U.S. Shareholder’s QEF Election. A purging election may require the U.S. holder to recognize taxable gain on the U.S. holder’s ADSs. No purging election is necessary for a U.S. holder that timely makes a QEF election for the first year in which the U.S. holder acquired our ADSs.

If we are determined to be a PFIC, the general tax treatment for U.S. holders described in this section will apply to indirect distributions and gains deemed to be realized by U.S. holders in respect of any of our subsidiaries that also may be determined to be PFICs.

If a U.S. holder owns ADSs during any taxable year in which we are a PFIC, the U.S. holder generally will be required to file an IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) with respect to the company, generally with the U.S. holder’s federal

 

S-16


income tax return for that year. If our company is a PFIC for a given taxable year, then you should consult your tax advisor concerning your annual filing requirements.

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. investors are urged to consult their own tax advisers with respect to the acquisition, ownership and disposition of the ADSs, the consequences to them of an investment in a PFIC, any elections available with respect to the ADSs and the IRS information reporting obligations with respect to the acquisition, ownership and disposition of the ADSs.

U.S. Federal Income Tax Consequences If We Are Not a PFIC. The description of the U.S. federal income tax consequences of the receipt of distributions and the sale or other taxable exchange of our ADSs, described in the following two section “ Distributions” and “ Sale, Exchange or Other Taxable Disposition of the ADSs,” apply only if we are not a PFIC in the relevant year and our stock is not subject to the rules described above under “ Passive Foreign Investment Company Considerations” because we were a PFIC with respect to a U.S. holder and its ADSs in a prior year.

Distributions. We do not expect to make any distribution in respect of our ADSs. If we are not treated as a PFIC under the rules described above under “ Passive Foreign Investment Company Considerations” and made any distribution in respect of our ADSs, the gross amount of the distribution (including any amount of foreign tax withheld in respect of such distribution) actually or constructively received by a U.S. holder with respect to ADSs will be taxable to the U.S. holder as a dividend to the extent of the U.S. holder’s pro rata share of our current and accumulated earnings and profits as determined under U.S. federal income tax principles. Distributions in excess of earnings and profits will be non-taxable to the U.S. holder to the extent of, and will be applied against and reduce, the U.S. holder’s adjusted tax basis in the ADSs. Distributions in excess of earnings and profits and such adjusted tax basis will generally be taxable to the U.S. holder as either long-term or short-term capital gain depending upon whether the U.S. holder’s holding period exceeds one year as of the time such distribution is received. However, since we do not calculate our earnings and profits under U.S. federal income tax principles, it is expected that any distribution will be reported as a dividend, even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above. Non-corporate U.S. holders may qualify for the preferential rates of taxation with respect to dividends on ADSs applicable to long-term capital gains (i.e., gains from the sale of capital assets held for more than one year) applicable to qualified dividend income (as discussed below) if we are a “qualified foreign corporation” and certain other requirements (discussed below) are met. A non-U.S. corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation (a) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for purposes of this provision and which includes an exchange of information provision, or (b) with respect to any dividend it pays on ADSs which are readily tradable on an established securities market in the United States. Our ADSs are currently listed on the New York Stock Exchange, which is an established securities market in the United States, and we expect the ADSs to be readily tradable on the New York Stock Exchange. However, there can be no assurance that the ADSs will be considered readily tradable on an established securities market in the United States in later years.

In general, the amount of a distribution paid to a U.S. holder in a foreign currency will be the dollar value of the foreign currency calculated by reference to the spot exchange rate on the day the Depositary receives the distribution, regardless of whether the foreign currency is converted into U.S. dollars at that time. Any foreign currency gain or loss a U.S. holder realizes on a subsequent conversion of foreign currency into U.S. dollars will be U.S. source ordinary income or loss. If dividends received in a foreign currency are converted into U.S. dollars on the day they are received, a U.S. holder should not be required to recognize foreign currency gain or loss in respect of the dividend.

Sale, Exchange or Other Taxable Disposition of the ADSs. A U.S. holder will generally recognize gain or loss for U.S. federal income tax purposes upon the sale, exchange or other taxable disposition of ADSs in an amount

 

S-17


equal to the difference between the U.S. dollar value of the amount realized from such sale or exchange and the U.S. holder’s tax basis in those ADSs, determined in U.S. dollars. Subject to the discussion under “ Passive Foreign Investment Company Considerations” above, this gain or loss will generally be a capital gain or loss. The adjusted tax basis in the ADSs generally will be equal to the cost of such ADSs. Capital gain from the sale, exchange or other taxable disposition of ADSs of a non-corporate U.S. holder is generally eligible for a preferential rate of taxation applicable to capital gains, if the non-corporate U.S. holder’s holding period determined at the time of such sale, exchange or other taxable disposition for such ADSs exceeds one year (i.e., such gain is long-term taxable gain). The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations. Any such gain or loss that a U.S. holder recognizes generally will be treated as U.S. source gain or loss for foreign tax credit limitation purposes.

For a cash basis taxpayer, units of foreign currency paid or received are translated into U.S. dollars at the spot rate on the settlement date of the purchase or sale. In that case, no foreign currency exchange gain or loss will result from currency fluctuations between the trade date and the settlement date of such a purchase or sale. An accrual basis taxpayer, however, may elect the same treatment required of cash basis taxpayers with respect to purchases and sales of the ADSs that are traded on an established securities market, provided the election is applied consistently from year to year. Such election may not be changed without the consent of the IRS. For an accrual basis taxpayer who does not make such election, units of foreign currency paid or received are translated into U.S. dollars at the spot rate on the trade date of the purchase or sale. Such an accrual basis taxpayer may recognize exchange gain or loss based on currency fluctuations between the trade date and the settlement date. Any foreign currency gain or loss a U.S. Holder realizes will be U.S. source ordinary income or loss.

Medicare Tax. Certain U.S. holders that are individuals, estates or trusts are subject to a 3.8% tax on all or a portion of their “net investment income,” which may include all or a portion of their dividend income and net gains from the disposition of ADSs. Each U.S. holder that is an individual, estate or trust is urged to consult its tax advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the ADSs.

Backup Withholding and Information Reporting. U.S. holders generally will be subject to information reporting requirements with respect to dividends on ADSs and on the proceeds from the sale, exchange or disposition of ADSs that are paid within the United States or through U.S.-related financial intermediaries, unless the U.S. holder is an “exempt recipient.” In addition, U.S. holders may be subject to backup withholding on such payments, unless the U.S. holder provides a taxpayer identification number and a duly executed IRS Form W-9 or otherwise establishes an exemption. Backup withholding is not an additional tax, and the amount of any backup withholding will be allowed as a credit against a U.S. 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.

Foreign Asset Reporting. Certain individual U.S. holders are required to report information relating to an interest in the ADSs, subject to certain exceptions (including an exception for shares held in accounts maintained by U.S. financial institutions) by filing IRS Form 8938 (Statement of Specified Foreign Financial Assets) with their federal income tax return. U.S. holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of the ADSs.

THE DISCUSSION ABOVE IS A SUMMARY OF THE MATERIAL CAYMAN AND U.S. FEDERAL INCOME TAX CONSEQUENCES OF AN INVESTMENT IN OUR ADSs OR ORDINARY SHARES AND IS BASED UPON LAWS AND RELEVANT INTERPRETATIONS THEREOF IN EFFECT AS OF THE DATE OF THIS PROSPECTUS, ALL OF WHICH ARE SUBJECT TO CHANGE, POSSIBLY WITH RETROACTIVE EFFECT. EACH PROSPECTIVE INVESTOR IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN INVESTMENT IN ADSs OR ORDINARY SHARES IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Cowen, under which we may issue and sell from time to time up to $80,000,000 of our ADSs through Cowen as our sales agent. Sales of our ADSs, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act.

Cowen will offer our ADSs subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and Cowen. We will designate the maximum amount of our ADSs to be sold through Cowen on a daily basis or otherwise determine such maximum amount together with Cowen. Subject to the terms and conditions of the sales agreement, Cowen will use its commercially reasonable efforts to sell on our behalf all of the ADSs requested to be sold by us. We may instruct Cowen not to sell ADSs if the sales cannot be effected at or above the price designated by us in any such instruction. Cowen or we may suspend the offering of our ADSs being made through Cowen under the sales agreement upon proper notice to the other party. Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.

The aggregate compensation payable to Cowen as sales agent is up to 3.0% of the gross sales price of the ADSs sold through it pursuant to the sales agreement. We have also agreed to reimburse Cowen up to $75,000 of Cowen’s reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel incurred by Cowen in connection with this offering and for certain other expenses, including Cowen’s FINRA counsel fees in an amount up to $15,000. We estimate that the total expenses of the offering payable by us, excluding commissions payable to Cowen under the sales agreement, will be approximately $550,000.

The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such ADSs.

Cowen will provide written confirmation to us following the close of trading on the New York Stock Exchange on each day in which ADSs are sold through it as sales agent under the sales agreement. Each confirmation will include the number of ADSs sold through it as sales agent on that day, the volume weighted average price of the ADSs sold, the percentage of the daily trading volume and the net proceeds to us.

We will report twice a year the number of ADSs sold through Cowen under the sales agreement, the net proceeds to us and the compensation paid by us to Cowen in connection with the sales of ADSs.

Settlement for sales of ADSs will occur, unless the parties agree otherwise, on the second business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sales of our ADSs on our behalf, Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Cowen will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Cowen against certain liabilities, including liabilities under the Securities Act. As sales agent, Cowen will not engage in any transactions that stabilize our ADSs. We have also agreed to contribute to payments Cowen may be required to make in respect of such liabilities.

Our ADSs are listed on the New York Stock Exchange and trade under the symbol “AMAM.” The transfer agent and registrar for our ADSs is JPMorgan Chase Bank, N.A.

The SEC maintains a web site that contains reports and information statements and other information about issuers, such as us, who file electronically with the SEC. The address of that website is www.sec.gov.

Incorporation by reference allows us to disclose important information to you by referring you to those other documents. This means that we can disclose important information by referring you to another document filed separately with the SEC. The information incorporated by reference is considered to be a part of this prospectus, and information that we file with the SEC after the date of this prospectus and before the termination or completion of this offering will also be deemed to be incorporated by reference into this prospectus and to be a part hereof from the date of filing of such documents and will automatically update and supersede previously filed information, including information contained in this document.

In all cases, you should rely on the later information over different information included in this prospectus or any accompanying prospectus supplement.
