Ordinary Shares

Pre-Funded Warrants to Purchase Ordinary Shares

We are offering   of our ordinary shares and, in lieu of ordinary shares to certain investors that so choose, pre-funded warrants to purchase   ordinary shares. The purchase price of each pre-funded warrant equals the price per share at which ordinary shares are being sold to the public in this offering, minus $0.0001, and the exercise price of each pre-funded warrant equals $0.0001 per share.

Our ordinary shares are listed on the Nasdaq Global Market under the symbol “WVE.” The last reported sale price of our ordinary shares on the Nasdaq Global Market on September 24, 2024 was $8.19 per ordinary share. There is no established public trading market for the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the pre-funded warrants on the Nasdaq Global Market, any other national securities exchange or any other nationally recognized trading system.

Investing in our securities involves a high degree of risk. See “Risk Factors” on page S-16 of this prospectus supplement and in the documents that are incorporated by reference into this prospectus supplement.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Delivery of the ordinary shares and pre-funded warrants is expected to be made on or about   , 2024. We have granted the underwriters an option for a period of 30 days to purchase up to an additional   ordinary shares. If the underwriters exercise the option in full, the total underwriting discounts and commissions payable by us will be  $   million, and the total proceeds to us, before expenses, will be $    million.

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are part of a “shelf” registration statement on Form S-3 (File No. 333-263251) that we initially filed with the Securities and Exchange Commission (the “SEC”) on March 3, 2022, and was declared effective on May 4, 2022. This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering of ordinary shares and pre-funded warrants and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference herein. The second part, the accompanying prospectus, including the documents incorporated by reference therein, provides more general information.

Generally, when we refer to this prospectus, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement and the information contained in the accompanying prospectus or any document incorporated by reference therein filed prior to the date of this prospectus supplement, you should rely on the information in this prospectus supplement; provided that 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 the accompanying prospectus—the statement in the document having the later date modifies or supersedes the earlier statement.

You should rely only on the information we have provided or incorporated by reference in this prospectus. We have not authorized anyone to provide you with information different from that contained or incorporated by reference in this prospectus.

RISK FACTORS

You should consider carefully the risks described below and discussed in the section titled “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2023, as updated by our subsequent filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), each of which is incorporated by reference in this prospectus supplement and the accompanying prospectus in their entirety, together with other information in this prospectus supplement and the accompanying prospectus, and the information and documents incorporated by reference in this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering before you make a decision to invest in our ordinary shares and pre-funded warrants. If any of the following events actually occur, our business, financial condition, results of operations or cash flow could be harmed. This could cause the trading price of our ordinary shares to decline and you may lose all or part of your investment. The risks below and incorporated by reference in this prospectus supplement and the accompanying prospectus are not the only ones we face. Additional risks not currently known to us or that we currently deem immaterial may also affect our business operations. Please also read carefully the section below titled “Special Note Regarding Forward-Looking Statements.”

Risks Related to this Offering

If you purchase ordinary shares in this offering, you will suffer immediate dilution of your investment.

The public offering price of our ordinary shares is substantially higher than the net tangible book value per share of our ordinary shares. Therefore, if you purchase our ordinary shares in this offering, you will pay a price per share that substantially exceeds our net tangible book value per share after giving effect to this offering. If you purchase ordinary shares in this offering, you will incur an immediate and substantial dilution in net tangible book value of $    per share. For a further description of the dilution that you will experience immediately after this offering, see the section titled “Dilution.” In addition, in the past, we have issued options to acquire ordinary shares at prices significantly below the offering price, have issued pre-funded warrants with an exercise price of $0.0001 per share, have granted restricted share units, and have issued shares under our ESPP at a discount to market prices. To the extent these outstanding options or pre-funded warrants are ultimately exercised, these restricted share units vest or we otherwise issue shares under the 2021 Plan or ESPP, you will incur additional dilution. Furthermore, if the pre-funded warrants offered hereby, are exercised, you will experience further dilution. For more information, see “Dilution.”

Our management will have broad discretion over the use of the net proceeds from this offering, and you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of this offering. Accordingly, you are relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds will be used appropriately. It is possible that the proceeds will be invested in a way that does not yield a favorable, or any, return for Wave.

Because we do not anticipate paying any cash dividends on our ordinary shares in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never declared or paid cash dividends on our ordinary shares. We anticipate that we will retain our earnings, if any, for future growth and therefore do not anticipate paying cash dividends in the future. As a result, only appreciation of the price of our ordinary shares will provide a return to shareholders.

S-16

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

Sales of a substantial number of our ordinary shares in the public markets could depress the market price of our ordinary shares and impair our ability to raise capital through the sale of additional equity securities. We, our directors and our executive officers have agreed not to sell, dispose of or hedge any ordinary shares or securities convertible into or exchangeable for shares of ordinary shares during the period from the date of this prospectus supplement continuing through and including the date 90 days after the date of this prospectus supplement, subject to certain exceptions. J.P. Morgan Securities LLC and Leerink Partners LLC may, in their discretion, release the restrictions on any such shares at any time without notice. In addition, certain of our shareholders have the right to require us to register the sales of their shares under the Securities Act of 1933, as amended (the “Securities Act”) under agreements between us and such shareholders, and we have an effective registration statement on Form S-3 that has registered the resale of shares held by certain of our shareholders. We cannot predict the effect that future sales of our ordinary shares would have on the market price of our ordinary shares.

There is no public market for the pre-funded warrants being offered in this offering.

There is no public trading market for the pre-funded warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any securities exchange or nationally recognized trading system, including the Nasdaq Global Market. Without an active market, the liquidity of the pre-funded warrants will be limited.

We will not receive a significant amount or any additional funds upon the exercise of the pre-funded warrants.

Each pre-funded warrant is exercisable for $0.0001 per ordinary share underlying such warrant which may be paid by way of a cashless exercise, meaning that the holder may not pay a cash purchase price upon exercise, but instead would receive upon such exercise the net number of ordinary shares determined according to the formula set forth in the pre-funded warrant. Accordingly, we will not receive a significant amount or any additional funds upon the exercise of the pre-funded warrants.

Holders of pre-funded warrants purchased in this offering will have no rights as ordinary shareholders until such holders exercise their pre-funded warrants and acquire our ordinary shares.

Until holders of pre-funded warrants acquire our ordinary shares upon exercise of the pre-funded warrants, holders of pre-funded warrants will have no rights with respect to the ordinary shares underlying such pre-funded warrants. Upon exercise of the pre-funded warrants, the holders will be entitled to exercise the rights of an ordinary shareholder only as to matters for which the record date occurs after the exercise date.

Significant holders or beneficial holders of our ordinary shares may not be permitted to exercise pre-funded warrants that they hold.

A holder of a pre-funded warrant will not be entitled to exercise any portion of any pre-funded warrant which, upon giving effect to such exercise, would cause (i) the aggregate number of ordinary shares beneficially owned by the holder (together with its affiliates) to exceed 19.99% of the number of our ordinary shares outstanding immediately after giving effect to the exercise, or (ii) the combined voting power of our securities beneficially owned by the holder (together with its affiliates) to exceed 19.99% of the combined voting power of all of our securities then outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. As a result, you may not be able to exercise your pre-funded warrants for our ordinary shares at a time when it would be financially beneficial for you to do so. In such circumstance you could seek to sell your pre-funded warrants to realize value, but you may be unable to do so in the absence of an established trading market for the pre-funded warrants.

S-17

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents we have filed with the SEC that are incorporated by reference contain “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act that involve substantial risks and uncertainties. In some cases, forward-looking statements are identified by the words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “future,” “goals,” “intend,” “likely,” “may,” “might,” “ongoing,” “objective,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “strategy,” “will” and “would” or the negative of these terms, or other comparable terminology intended to identify statements about the future. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements.

Although we believe that we have a reasonable basis for each forward-looking statement contained in this prospectus supplement, the accompanying prospectus and the documents that we have filed with the SEC that are incorporated by reference, such statements are based on a combination of facts and factors currently known by us and our expectations of the future, about which we cannot be certain. Forward-looking statements include statements about:

S-18

You should refer to the section titled “Risk Factors” of this prospectus supplement and in our other filings with the SEC for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure that the forward-looking statements in this prospectus supplement, the accompanying prospectus or the documents we have filed with the SEC that are incorporated by reference will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, these statements should not be regarded as representations or warranties by us or any other person that we will achieve our objectives and plans in any specified time frame, or at all. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus supplement, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements as predictions of future events.

You should read this prospectus supplement, the accompanying prospectus, the documents that we have incorporated by reference herein and therein and the documents we have filed as exhibits to the registration statement, of which this prospectus supplement is a part, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

S-19

USE OF PROCEEDS

We estimate that the net proceeds we will receive in this offering will be approximately $   million, or approximately $   million if the underwriters exercise their option to purchase additional ordinary shares in full, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We will receive nominal proceeds, if any, from the exercise of the pre-funded warrants.

We intend to use the net proceeds from this offering for general corporate purposes, including, but not limited to, working capital, capital expenditures and general and administrative expenses.

Our expected use of the net proceeds from this offering represents our current intentions based upon our present plans and business conditions. The amounts and timing of our actual use of net proceeds will vary depending on numerous factors, including the relative success and cost of our research, preclinical and clinical development programs, whether we are able to enter into future collaborations, and any unforeseen delays or cash needs. As a result, our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds of this offering. In addition, we might decide to postpone or not pursue these planned trials and activities or other development activities if the net proceeds from this offering and the other sources of cash are less than, or do not last as long as, expected.

Pending their use, we plan to invest the net proceeds from this offering in short- and intermediate-term, interest- bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

S-20

DIVIDEND POLICY

We have never declared or paid any dividends on our ordinary shares. We currently anticipate that we will retain any future earnings for the operation and expansion of our business. Accordingly, we do not currently anticipate declaring or paying any cash dividends on our ordinary shares for the foreseeable future. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on then-existing conditions, including our financial condition, results of operations, contractual restrictions (including in the agreements governing our credit facilities), capital requirements, business prospects and other factors our board of directors may deem relevant. We may, by ordinary resolution, declare dividends, but (without prejudice to the powers of the Company to pay interest on share capital as provided in our constitution) no dividend is payable (i) except out of the profits of the Company or (ii) in excess of the amount recommended by our directors.

S-21

CAPITALIZATION

The following table sets forth our cash and cash equivalents and our capitalization as of June 30, 2024:

This table should be read together with our consolidated financial statements and related notes and the other financial information included or incorporated by reference in this prospectus supplement and the accompanying prospectus.

The number of ordinary shares to be outstanding after this offering is based on an aggregate of 122,479,289 ordinary shares outstanding as of June 30, 2024, and excludes:

S-22

DILUTION

If you invest in our ordinary shares, your ownership interest will be diluted immediately to the extent of the difference between the offering price per ordinary share and the as adjusted net tangible book value per ordinary share after this offering.

As of June 30, 2024, our historical net tangible book value was $5.1 million, or $0.04 per ordinary share. Historical net tangible book value per share represents the amount of our total tangible assets less total liabilities and Series A preferred shares, divided by the number of outstanding ordinary shares.

After giving effect to the sale of   ordinary shares in this offering at the public offering price of $    per share and pre-funded warrants to purchase up to     of our ordinary shares at the public offering price of $    per pre-funded warrant (which equals the public offering price per ordinary share less the $0.0001 per share exercise price of each such pre-funded warrant) (and excluding ordinary shares issued and any proceeds received upon exercise of the pre-funded warrants or any resulting accounting associated with the pre-funded warrants), and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our net tangible book value as of June 30, 2024 would have been $ million or $ per share. This amount represents an immediate increase in net tangible book value of $ per share to our existing shareholders and an immediate dilution in net tangible book value of $ per share to new investors purchasing our ordinary shares and pre-funded warrants in this offering. We determine dilution by subtracting the net tangible book value per share after the offering from the amount of cash that a new investor paid for an ordinary share.

The following table illustrates this dilution on a per share basis to new investors:

If the underwriters exercise in full their option to purchase an additional ordinary shares at the public offering price of $   per share, the as adjusted net tangible book value per share after giving effect to this offering would be $   per share, representing an immediate increase to existing shareholders of $ per share, and immediate dilution in net tangible book value of $    per share to investors participating in this offering.

If holders of pre-funded warrants exercise the pre-funded warrants, the as adjusted net tangible book value per share of our ordinary shares after giving effect to this offering would be $     per share, and the dilution in net tangible book value per share to investors purchasing ordinary shares in this offering would be $     per share.

The table and discussion above does not include:

S-23

To the extent that outstanding options or pre-funded warrants are exercised, outstanding RSUs vest, or shares are otherwise issued under the 2021 Plan or ESPP or upon conversion of Series A preferred shares, you will 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 may result in further dilution to our shareholders.

S-24

DESCRIPTION OF PRE-FUNDED WARRANTS

The following is a brief summary of certain terms and conditions of the pre-funded warrants being offered by this prospectus supplement. The following description is subject in all respects to the provisions contained in the pre-funded warrants.

Form

The pre-funded warrants will be issued as individual warrant agreements to the investors. The form of pre-funded warrant will be filed as an exhibit to our Current Report on Form 8-K that we expect to file with the SEC in connection with this offering.

Term and Exercisability

The pre-funded warrants are exercisable at any time after their original issuance and on or prior to 5:00 p.m. (New York City time) on the five-year anniversary of the original issuance date. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full of the exercise price in immediately available funds for the number of ordinary shares purchased upon such exercise. As an alternative to payment in immediately available funds, the holder may elect to exercise the pre-funded warrant through a cashless exercise, in which the holder would receive upon such exercise the net number of ordinary shares determined according to the formula set forth in the pre-funded warrant. No fractional ordinary shares will be issued in connection with the exercise of a pre-funded warrant.

Exercise Limitations

Under the pre-funded warrants, unless and until the Shareholder Approval (as defined below) is obtained, we may not effect the exercise of any pre-funded warrant, and a holder will not be entitled to exercise any portion of any pre-funded warrant, which, upon giving effect to such exercise, would cause (i) the aggregate number of our ordinary shares beneficially owned by the holder (together with its affiliates) to exceed 19.99% of the number of our ordinary shares outstanding immediately after giving effect to the exercise, or (ii) the combined voting power of our securities beneficially owned by the holder (together with its affiliates) to exceed 19.99% of the combined voting power of all of our securities then outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants.

Upon the written request of the holder delivered to us and subsequent to December 31, 2024, we shall use commercially reasonable efforts to obtain shareholder approval (the “Shareholder Approval”), at our next regularly scheduled annual general meeting of shareholders, for the issuance of the pre-funded warrant shares upon the exercise of all or any portion of the pre-funded warrants such that such issuance of pre-funded warrant shares will comply with the Listing Rules of the Nasdaq Stock Market, including, without limitation, Listing Rule 5635, and with applicable Singapore law. In the event that the holder requests the Shareholder Approval, we use commercially reasonable efforts to obtain Shareholder Approval at our next regularly scheduled annual general meeting, and Shareholder Approval is not obtained at such meeting for any reason, then the holder may again request Shareholder Approval each year pursuant to and subject to the terms of the pre-funded warrants, at each of our subsequent regularly scheduled annual general meetings that occur prior to the termination date of the pre-funded warrants. We shall not be obligated to seek the Shareholder Approval at any shareholder meeting other than our regularly scheduled annual shareholder meeting and such written request of the holder must be received by us at least 90 days in advance of such annual meeting.

Exercise Price

The exercise price per whole share of our ordinary shares purchasable upon the exercise of the pre-funded warrants is $0.0001 per ordinary share. The exercise price of the pre-funded warrants and the number of our

S-25

ordinary shares issuable upon exercise of the pre-funded warrants is subject to appropriate adjustment in the event of certain share dividends and distributions, share splits, share combinations, reclassifications or similar events affecting our ordinary shares.

Transferability

Subject to applicable laws, the pre-funded warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing

We do not plan on applying to list the pre-funded warrants on the Nasdaq Global Market, any other national securities exchange or any other nationally recognized trading system.

Fundamental Transactions

In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our ordinary shares, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding ordinary shares, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding ordinary shares, upon consummation of such a fundamental transaction, the holders of the pre-funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the pre-funded warrants.

No Rights as a Shareholder

Except by virtue of such holder’s ownership of our ordinary shares, the holder of a pre-funded warrant does not have the rights or privileges of a holder of our ordinary shares, including any voting rights, until the holder exercises the pre-funded warrant. In the event of certain distributions, including cash dividends, if any, to all holders of our ordinary shares for no consideration, the holder of a pre-funded warrant shall be entitled to participate in such distributions to the same extent as if a holder of our ordinary shares, subject to not exceeding the ownership limitations described above under “—Exercise Limitations,” in which case such distribution shall be held in abeyance for the benefit of such holder until the earlier of such time as the ownership limitations would not be exceeded or the warrant is exercised.

S-26

CERTAIN MATERIAL TAX CONSIDERATIONS

Material U.S. Federal Income Tax Considerations for U.S. Holders

This discussion sets forth a summary of material U.S. federal income tax consequences to U.S. Holders (as defined below) of the purchase, ownership and disposition of the ordinary shares or pre-funded warrants. The discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, final, temporary and proposed regulations thereunder, published rulings and court decisions, all as currently in effect and all subject to change at any time, possibly with retroactive effect. We cannot assure you that a change in law will not alter significantly the tax considerations described in this summary. We have not sought and do not expect to seek any rulings from the U.S. Internal Revenue Service (the “IRS”) regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the purchase, ownership or disposition of our ordinary shares or pre-funded warrants that differ from those discussed below.

This discussion addresses only material U.S. federal income tax considerations to U.S. Holders that acquire their ordinary shares or pre-funded warrants in this offering and that hold those ordinary shares or pre-funded warrants as capital assets (generally, property held for investment) and does not purport to be a comprehensive description of all tax considerations that may be relevant to a particular person’s decision to acquire the ordinary shares or pre-funded warrants. In addition, this discussion does not address the U.S. federal income tax consequences to any special class of U.S. Holders, including without limitation, holders of (directly, indirectly or constructively and including any future acquisitions of ordinary shares or pre-funded warrants) 10% or more of the total voting power or value of our ordinary shares (except as discussed below), dealers in securities or currencies, banks, tax-exempt organizations, qualified retirement plans, individual retirement accounts and other tax-deferred accounts, life insurance companies, financial institutions, broker-dealers, regulated investment companies, real estate investment trusts, traders in securities that elect the mark-to-market method of accounting for their securities holdings, persons that hold securities that are a hedge or that are hedged against currency or interest rate risks or that are part of a straddle, conversion or “integrated” transaction, persons that are not U.S. Holders (as defined below), persons who acquired our ordinary shares or pre-funded warrants pursuant to the exercise of an employee share option or otherwise as compensation, S corporations, partnerships or other entities classified as pass-through entities for U.S. federal income tax purposes (and investors therein) and U.S. Holders whose functional currency for U.S. federal income tax purposes is not the U.S. dollar. This discussion does not address the effect of the U.S. federal alternative minimum tax, or U.S. federal gift, estate or generation-skipping transfer tax, or any state, local or foreign tax laws on a holder of ordinary shares or pre-funded warrants.

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of ordinary shares or pre-funded warrants that is for U.S. federal income tax purposes:

If a partnership or an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds our ordinary shares or pre-funded warrants, the U.S. federal income tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. Partnerships that hold our ordinary shares or pre-funded warrants and partners in such partnerships should consult their own tax advisors regarding the particular U.S. federal, state, local and foreign tax consequences of owning and disposing of ordinary shares or pre-funded warrants.

S-27

If you are considering the purchase of our ordinary shares or pre-funded warrants, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you of the purchase, ownership and disposition of our ordinary shares or pre-funded warrants, as well as the consequences to you arising under other U.S. federal tax laws and the laws of any applicable state, local, non-U.S. or other taxing jurisdiction and any applicable tax treaty in light of your particular circumstances.

Pre-Funded Warrants

Although it is not entirely free from doubt, a pre-funded warrant should be treated as an ordinary share for U.S. federal income tax purposes and a U.S. Holder of a pre-funded warrant should generally be taxed in the same manner as a U.S. Holder of such an ordinary share, as described below. Accordingly, no gain or loss should be recognized (other than with respect to cash paid in lieu of a fractional share) upon the exercise of a pre-funded warrant and, upon exercise, the holding period of a pre-funded warrant should carry over to the ordinary share received. Similarly, the tax basis of the pre-funded warrant should carry over to the share received upon exercise, increased by the exercise price per share. If a pre-funded warrant expires without being exercised, the U.S. Holder thereof should recognize a capital loss in an amount equal to such U.S. Holder’s tax basis in the pre-funded warrant. This loss will be long-term capital loss if, at the time of the expiration, the U.S. Holder’s holding period in the pre-funded warrant is longer than one year. The deductibility of capital losses is subject to limitations. In addition, a U.S. Holder may, in its discretion, elect to undertake a cashless exercise of the pre-funded warrants into ordinary shares. The U.S. federal income tax treatment of a cashless exercise of pre-funded warrants into ordinary shares is unclear, and the tax consequences of a cashless exercise could differ from the consequences upon the exercise of a pre-funded warrant described in the preceding paragraph. U.S. Holders should consult their own tax advisors regarding the U.S. federal income tax consequences of a cashless exercise of pre-funded warrants.

However, characterizing pre-funded warrants as ordinary shares for U.S. federal income tax purposes is not binding on the IRS, and the IRS may treat our pre-funded warrants as warrants to acquire our ordinary shares.

In that case, the amount and character of a U.S. Holder’s gain with respect to an investment in pre-funded warrants could change, and a U.S. Holder may not be entitled to timely make the “qualified electing fund” election described below with respect to pre-funded warrants to mitigate PFIC consequences in the event that we are classified as a PFIC. Based on the foregoing, the amount and character of a U.S. Holder’s gain with respect to an investment in our pre-funded warrants could be materially different than the discussion set forth below.

In addition, the market-to-market election will likely not be available with respect to the pre-funded warrants in the event that we are classified as a PFIC because the pre-funded warrants are not treated as “marketable stock” as they are not expected to be “regularly traded” (as such terms are defined below). Similarly, assuming we are not treated as a “qualified foreign corporation” (within the meaning of applicable U.S. Treasury Regulations and other IRS guidance), dividends received with respect to pre-funded warrants will likely not qualify for the lower rates of tax applicable to “qualified dividend income” (as described below) because the pre-funded warrants are not “readily tradable” on an established securities market in the United States (within the meaning of applicable U.S. Treasury Regulations).

Accordingly, each U.S. Holder should consult his, her or its tax advisor regarding the risks associated with the acquisition of pre-funded warrants pursuant to this offering (including potential alternative characterizations). Except where specifically noted, the remainder of this discussion assumes a pre-funded warrant is treated as an ordinary share for U.S. federal income tax purposes.

S-28

Dividends and Other Distributions

As described in the section titled “Dividend Policy,” we do not currently anticipate declaring or paying dividends to holders of our ordinary shares or pre-funded warrants for the foreseeable future. However, subject to the discussion below of the passive foreign investment company (“PFIC”) rules, if we do make distributions of cash or other property in respect of our ordinary shares or pre-funded warrants, other than certain pro rata distributions of ordinary shares, the U.S. dollar amount of the gross amount of any such distribution will be taxable as a dividend, to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Such income will be includable in your gross income on the day actually or constructively received by you. The amount of any distribution of property other than cash will be the fair market value of that property on the date of distribution. To the extent the amount of the distribution exceeds our current and accumulated earnings and profits (as determined under U.S. federal income tax principles), such excess amount will be treated first as a tax-free return of your tax basis in your ordinary shares or pre-funded warrants, and then, to the extent such excess amount exceeds your tax basis in your ordinary shares or pre-funded warrants, as capital gain. We, however, may not calculate earnings and profits in accordance with U.S. federal income tax principles. In that case, we intend to treat the full amount of any distribution by us to U.S. Holders as a dividend for U.S. federal income tax purposes.

A U.S. Holder may be entitled, subject to certain limitations, to a credit against its U.S. federal income tax liability, or to a deduction, if elected, in computing its U.S. federal taxable income, for nonrefundable non-U.S. income taxes withheld from dividends.

The amount of the dividend will generally be treated as foreign-source dividend income to U.S. Holders. However, if we are treated as a “United States-owned foreign corporation,” a portion of dividends paid by us may be treated as U.S. source for purposes of determining the foreign tax credit limitation. We will be treated as a United States-owned foreign corporation if 50% or more of the total value or total voting power of all classes of our shares is owned, directly, indirectly or by attribution, by 10% U.S. Shareholders (as defined below). We do not believe that we are currently treated as a United States-owned foreign corporation, but there is no assurance that we will not be treated as such as a result of this offering or otherwise in the future. U.S. Treasury Regulations that were issued in 2022 also require non-U.S. income tax laws to meet certain requirements in order for taxes imposed under such laws to be eligible for credit. We have not determined whether these requirements have been met with respect to any such non-U.S. withholding taxes. A recent notice from the IRS indicates, however, that the U.S. Department of the Treasury (“Treasury”) and the IRS are considering proposing amendments to such U.S. Treasury Regulations and allows, subject to certain conditions, taxpayers to defer the application of many aspects of such U.S. Treasury Regulations for taxable years ending before the date that notice or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other guidance). For purposes of the foreign tax credit limitation, dividends paid by us generally will constitute “passive category income.” The rules relating to the foreign tax credit or deduction, if elected, are complex and U.S. Holders should consult their tax advisors concerning their availability in their particular circumstances.

U.S. Holders of our ordinary shares or pre-funded warrants that are corporations generally will not be entitled to claim a “dividends received deduction” with respect to dividends paid on the ordinary shares or pre-funded warrants.

Dividends received by a non-corporate U.S. Holder with respect to our ordinary shares, including an individual, may qualify for the lower rates of tax applicable to “qualified dividend income,” provided that (i) we are not a PFIC for our taxable year in which the dividend is paid or in the preceding taxable year, (ii) certain holding period and other requirements are met and (iii) our ordinary shares are readily tradable on an established securities market in the United States. As discussed above, assuming we are not treated as a “qualified foreign

corporation” (within the meaning of applicable U.S. Treasury Regulations and other IRS guidance), dividends received by U.S. Holders with respect to pre-funded warrants will likely not qualify for the lower rates of tax applicable to “qualified dividend income.” You should consult your own tax advisors regarding the availability of the lower tax rates applicable to qualified dividend income for any dividends that we pay with respect to the ordinary shares or pre-funded warrants, as well as the effect of any change in applicable law.

S-29

Constructive Distributions on Pre-Funded Warrants

A U.S. Holder of pre-funded warrants may, in some circumstances, be deemed to have received a distribution subject to U.S. federal income tax as a result of an adjustment or the non-occurrence of an adjustment to the exercise price or number of ordinary shares issuable upon exercise of such pre-funded warrants. In addition, in certain circumstances, the pre-funded warrants are not entitled to any distributions until such pre-funded warrant is exercised. Upon the exercise of such pre-funded warrant, a U.S. Holder shall be entitled to receive distributions declared on our ordinary shares prior to the exercise of such pre-funded warrant. It is possible that such entitlement to distributions may cause the declaration of a distribution on our ordinary shares to be currently taxable to U.S. Holders of pre-funded warrants.

U.S. Holders should consult their tax advisors regarding the proper treatment of any adjustments to pre-funded warrants.

Disposition of the Ordinary Shares or Pre-Funded Warrants

You will recognize gain or loss on a sale, exchange or other taxable disposition of our ordinary shares or pre-funded warrants in an amount equal to the difference between the amount realized (in U.S. dollars) on the sale, exchange or taxable disposition and your tax basis (in U.S. dollars) in the ordinary shares or pre-funded warrants. Subject to the PFIC rules discussed below, such gain or loss generally will be capital gain or loss. If you are a non-corporate U.S. Holder, including an individual, that has held the ordinary shares or pre-funded warrants for more than one year, you may be eligible for reduced tax rates. The deductibility of capital losses is subject to limitations.

Any gain or loss that you recognize on a disposition of our ordinary shares or pre-funded warrants generally will be treated as U.S.-source income or loss for foreign tax credit limitation purposes. You should consult your own tax advisors regarding the proper treatment of gain or loss, as well as the availability of a foreign tax credit, in your particular circumstances.

Passive Foreign Investment Company

Based on the current and anticipated value of our assets and the current and expected composition of our income and assets, we do not believe we were a PFIC for U.S. federal income tax purposes for our most recent taxable year ending December 31, 2023 nor expect to be treated as a PFIC for U.S. federal income tax purposes for our current taxable year ending December 31, 2024; however, there can be no assurance that we will not be considered a PFIC for any taxable year. The determination of PFIC status is based on an annual determination that cannot be made until the close of a taxable year, involves extensive factual investigation, including ascertaining the fair market value of all of our assets on a quarterly basis and the character of each item of income that we earn, and is subject to uncertainty in several respects. Moreover, our ability to earn specific types of income that we currently treat as non-passive for purposes of the PFIC rules is uncertain with respect to future years.

Accordingly, we cannot assure you that we will not be treated as a PFIC for our current taxable year ending December 31, 2024, or for any future taxable year or that the IRS will not take a contrary position. Mintz, Levin,

Cohn, Ferris, Glovsky and Popeo, P.C., our U.S. tax counsel, therefore expresses no opinion with respect to our PFIC status for any taxable year or our expectations relating to such status set forth in this discussion.

A non-U.S. corporation will be treated as a PFIC for U.S. federal income tax purposes for any taxable year if, applying applicable look-through rules with respect to certain subsidiary entities (as discussed in more detail below), either:

S-30

For these purposes, we will be treated as owning a proportionate share of the assets and earning a proportionate share of the income of any other corporation in which we own, directly or indirectly, at least 25% by value of the stock or shares. Subject to various exceptions, passive income generally includes dividends, interest, capital gains, royalties and rents (other than certain royalties and rents derived in the active conduct of a trade or business and not derived from a related person).

We must make a separate determination each year as to whether we are a PFIC. As a result, our PFIC status may change. Because PFIC status must be determined annually based on tests which are factual in nature, our PFIC status in future years will depend on our income, assets and activities in those years. Furthermore, because the value of our gross assets is likely to be determined in large part by reference to our market capitalization and the value of our goodwill, a decline in the value of our shares could affect the determination of whether we are a PFIC. There can be no assurance that we will not be considered a PFIC for any taxable year. If we are a PFIC for any taxable year during which you hold ordinary shares or pre-funded warrants, we generally will continue to be treated as a PFIC for all succeeding years during which you hold the ordinary shares or pre-funded warrants. However, if we cease to be a PFIC, you may avoid some of the adverse effects of the PFIC regime by making a “deemed sale” election with respect to the ordinary shares or pre-funded warrants, as applicable.

If we are or become a PFIC in a taxable year in which we pay a dividend or the prior taxable year, the preferential tax rates discussed above with respect to dividends paid to non-corporate U.S. Holders would not apply. In addition, if we are a PFIC for any taxable year during which you hold ordinary shares or pre-funded warrants, in the absence of a “qualifying electing fund” election (which, as noted below, may not be available to you), you will be subject to special tax rules with respect to any “excess distribution” that you receive and any gain you realize from a sale or other disposition (including, under certain circumstances, a pledge) of the ordinary shares or pre-funded warrants, unless you make a “mark-to-market” election as discussed below. Distributions (including constructive distributions with respect to pre-funded warrants) you receive in a taxable year that are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for the ordinary shares or pre-funded warrants will be treated as an excess distribution. Under these special tax rules:

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the ordinary shares or pre-funded warrants cannot be treated as capital, even if you hold the ordinary shares or pre-funded warrants as capital assets.

If we are treated as a PFIC with respect to you for any taxable year, to the extent any of our subsidiaries are also PFICs, you will be deemed to own shares in such lower-tier PFICs that are directly or indirectly owned by us in the proportion that the value of the ordinary shares you own bears to the value of all of our ordinary shares, and you may be subject to the rules described in the preceding paragraphs with respect to the shares of such lower-tier PFICs you are deemed to own. You should consult your own tax advisor regarding the application of the PFIC rules to any of our subsidiaries including as a result of the changes included as part of the Tax Cuts and Jobs Act (the “Tax Act”).

S-31

In certain circumstances, a U.S. Holder of shares in a PFIC may avoid the adverse tax consequences described above by making a “qualified electing fund” election to include in income its pro rata share of the corporation’s income on a current basis. However, you may make a qualified electing fund election with respect to your ordinary shares or pre-funded warrants only if we agree to furnish you annually with a PFIC annual information statement as specified in the applicable U.S. Treasury Regulations. As discussed above, a timely qualified electing fund election may not be available with respect to the pre-funded warrants.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market election with respect to such stock to elect out of the tax treatment discussed above. If you make a valid mark-to-market election for the ordinary shares you will include in income each year an amount equal to the excess, if any, of the fair market value of the ordinary shares as of the close of your taxable year over your adjusted basis in such ordinary shares. You are allowed a deduction for the excess, if any, of the adjusted basis of the ordinary shares over their fair market value as of the close of the taxable year. However, deductions are allowable only to the extent of any net mark-to-market gains on the ordinary shares included in your income for prior taxable years. Amounts included in your income under a mark-to-market election, as well as gain on the actual sale or other disposition of the ordinary shares, are treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ordinary shares, as well as to any loss realized on the actual sale or disposition of the ordinary shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such ordinary shares. Your basis in the ordinary shares will be adjusted to reflect any such income or loss amounts. If you make such an election, the tax rules that apply to distributions by corporations that are not PFICs would apply to distributions by us, except that the preferential tax rate discussed above under the heading “—Dividends and Other Distributions” would not apply.

The mark-to-market election is available only for “marketable stock,” which is stock that is traded in other than de minimis quantities on at least 15 days during each calendar quarter “regularly traded” on a qualified exchange or other market, as defined in applicable U.S. Treasury Regulations. The Nasdaq Global Market is a qualified exchange. We anticipate that our ordinary shares will continue to be regularly traded on the Nasdaq Global Market, and therefore, in 2024 and any subsequent year in which our ordinary shares continue to be regularly traded, the mark-to-market election would be available to a U.S. Holder of our ordinary shares if we are or become a PFIC. As discussed above, the “market-to-market” election will likely not be available with respect to the pre-funded warrants. If any of our subsidiaries are or become PFICs, the mark-to-market election will not be available with respect to the shares of such subsidiaries that are treated as owned by you. Consequently, you could be subject to the PFIC rules with respect to income of the lower-tier PFICs the value of which already had been taken into account indirectly via mark-to-market adjustments.

U.S. Holders should consult their tax advisors regarding the availability and advisability of making a mark-to-market election in their particular circumstances.

If you hold ordinary shares or pre-funded warrants in any year in which we are a PFIC, you will also be subject to annual information reporting requirements.

The PFIC rules are complex, and you should consult your own tax advisors regarding the application of the PFIC rules to your investment in our ordinary shares or pre-funded warrants and the availability, application and consequences of the elections discussed above.

Disposition of Foreign Currency

U.S. Holders are urged to consult their tax advisors regarding the tax consequences of receiving, converting or disposing of any non-U.S. currency received as dividends on our ordinary shares or pre-funded warrants (if any) or on the sale or other disposition of our ordinary shares or pre-funded warrants.

S-32

Controlled Foreign Corporation

The changes included in the Tax Act can impact the tax treatment of a U.S. person treated as a 10% U.S. Shareholder (as defined below). The Tax Act eliminated the prohibition on “downward attribution” from non-U.S. persons to U.S. persons under Section 958(b)(4) of the Code for purposes of determining constructive stock ownership under the controlled foreign corporation (“CFC”) rules. As a result, our U.S. subsidiary will be deemed to own all of the stock of our non-U.S. subsidiaries held by the Company for CFC purposes. To the extent one of our non-U.S. subsidiaries is treated as a CFC for any taxable year, each U.S. person treated as a 10% U.S. Shareholder (as defined below) with respect to such CFC that held our ordinary shares or pre-funded warrants directly or indirectly through one or more non-U.S. entities (including the Company) as of the last day of such taxable year that the subsidiary was a CFC generally would be required to include in gross income as ordinary income its pro rata share of certain investment income of the CFC (with certain adjustments), regardless of whether that income was actually distributed to such U.S. person. A “10% U.S. Shareholder” of a non-U.S. corporation includes any U.S. person that owns (or is treated as owning) stock of the non-U.S. corporation possessing 10% or more of the total voting power or total value of such non-U.S. corporation’s stock. To the extent that a non-U.S. subsidiary is treated as a CFC and as a PFIC for any taxable year, such non-U.S. subsidiary will be treated as a CFC and not as a PFIC with respect to any 10% U.S. Shareholder. Failure to comply with these reporting and tax paying obligations may subject a 10% U.S. Shareholder to significant monetary penalties and may prevent the statute of limitations with respect to such shareholder’s U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist investors in determining whether any investor is treated as a 10% U.S. Shareholder with respect to any such CFC or furnish to any 10% U.S. Shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations.

YOU ARE STRONGLY URGED TO CONSULT YOUR OWN TAX ADVISORS TO DETERMINE WHETHER YOUR OWNERSHIP OF THE ORDINARY SHARES OR PRE-FUNDED WARRANTS WILL CAUSE YOU TO BECOME A 10% U.S. SHAREHOLDER AND THE IMPACT OF SUCH A CLASSIFICATION.

Information Reporting and Backup Withholding

Unless an exception applies, information reporting to the IRS generally will be required with respect to payments on the ordinary shares or pre-funded warrants (including constructive distributions with respect to pre-funded warrants) and proceeds of the sale of the ordinary shares or pre-funded warrants paid to U.S. Holders, other than corporations and other exempt recipients. Backup withholding, currently at the rate of 24%, may apply to those payments if such a holder fails to provide a taxpayer identification number to the paying agent and to certify that no loss of exemption from backup withholding has occurred. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded or credited against the holder’s U.S. federal income tax liability, if any, provided the required information is furnished to the IRS.

In addition, certain U.S. Holders who are individuals that hold certain foreign financial assets (which may include the ordinary shares or pre-funded warrants), or who have a beneficial interest in or signatory authority over certain foreign financial accounts, are required to report information relating to such assets or accounts, subject to certain exceptions.

You should consult your own tax advisor regarding the application of the information reporting and backup withholding requirements to your particular situation.

Medicare Tax

Certain U.S. Holders that are individuals, estates or trusts are required to pay up to an additional 3.8% tax on, among other things, interest, dividends and gains from the sale or other disposition of capital assets. Special rules apply and certain elections are available for certain U.S. Holders that are subject to the 3.8% tax on net investment income and hold shares in a PFIC. Each U.S. Holder that is an individual, estate or trust should consult its own tax advisors regarding the effect, if any, of this tax provision on their ownership and disposition of ordinary shares or pre-funded warrants.

S-33

Information with Respect to Foreign Financial Assets

Certain U.S. Holders may be required to report information relating to an interest in our ordinary shares or pre-funded warrants, subject to certain exceptions (including an exception for ordinary shares or pre-funded warrants held in accounts maintained by certain U.S. financial institutions). U.S. Holders should consult their tax advisors regarding the effect, if any, of this requirement on their ownership and disposition of the ordinary shares or pre-funded warrants.

Transfer Reporting Requirements

A U.S. Holder (including a U.S. tax-exempt entity) that acquires equity of a non-U.S. corporation may be required to file a Form 926 or a similar form with the IRS under certain circumstances. Penalties may be imposed upon a U.S. Holder that fails to comply with the reporting requirements. U.S. Holders should consult their tax advisors regarding the applicability of this requirement to the acquisition or disposition of the ordinary shares or pre-funded warrants.

Disclosure of Reportable Transactions

If a U.S. Holder sells or disposes of the ordinary shares or pre-funded warrants at a loss or otherwise incurs certain losses that meet certain thresholds, such U.S. Holder may be required to file a disclosure statement with the IRS. Failure to comply with these and other reporting requirements could result in the imposition of significant penalties.

POTENTIAL PURCHASERS OF OUR ORDINARY SHARES OR PRE-FUNDED WARRANTS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE U.S. FEDERAL, STATE, LOCAL, AND NON-U.S. INCOME, GIFT, ESTATE OR GENERATION- SKIPPING TRANSFER, AND OTHER TAX AND TAX TREATY CONSIDERATIONS OF PURCHASING, OWNING AND DISPOSING OF OUR ORDINARY SHARES.

Material Singapore Tax Considerations

The following discussion is a summary of material Singapore income tax, stamp duty and estate duty considerations relevant to the purchase, ownership and disposition of our ordinary shares by an investor who is not tax resident or domiciled in Singapore and who does not carry on business or otherwise have a presence in Singapore. The statements made herein regarding taxation are based on certain aspects of the tax laws of Singapore and administrative guidelines issued by the relevant authorities in force as of the date hereof and are subject to any changes in such laws or administrative guidelines, or in the interpretation of those laws or guidelines, occurring after such date, which changes could be made on a retroactive basis. The statements made herein do not describe all of the tax considerations that may be relevant to all our shareholders, some of which (such as dealers in securities) may be subject to different rules. The statements are not intended to be and do not constitute legal or tax advice and no assurance can be given that courts or fiscal authorities responsible for the administration of such laws will agree with the interpretation adopted therein. Each prospective investor should consult an independent tax advisor regarding all Singapore income and other tax consequences applicable to them from owning or disposing of our ordinary shares in light of the investor’s particular circumstances.

Income Taxation Under Singapore Law

Dividend Distributions with Respect to Ordinary Shares

On the basis that a company is not tax resident in Singapore for Singapore tax purposes, dividends paid by the company should generally be considered as sourced outside Singapore (unless our ordinary shares are held as part of a trade or business carried on in Singapore in which event the holders of such shares may be taxed on the dividends as they are derived).

S-34

Foreign-sourced dividends received or deemed received in Singapore by an individual not resident in Singapore would be exempt from Singapore income tax. This exemption will also apply in the case of a Singapore tax resident individual who receives such foreign-sourced income in Singapore (except where such income is received through a partnership in Singapore).

Foreign-sourced dividends received or deemed received by corporate investors in Singapore will be liable for Singapore tax. However, if the conditions for the exemption of specified foreign-sourced income are met, foreign-sourced dividends received by corporate investors resident in Singapore would be exempt from Singapore tax.

Foreign-sourced dividends received or deemed received in Singapore on or after June 1, 2003 by a Singapore resident corporate taxpayer is exempt from tax, provided certain prescribed conditions are met, including the following:

In the case of dividends paid by a company resident in a territory from which the dividends are received, the “subject to tax condition” in (a) above is considered met where tax is paid in that territory by such company in respect of its income out of which such dividends are paid or tax is paid on such dividends in that territory from which such dividends are received. Certain concessions and clarifications have also been announced by the Inland Revenue Authority of Singapore (“IRAS”) with respect to the above conditions.

Capital Gains upon Disposition of Ordinary Shares

Under current Singapore tax law, there is no tax on capital gains. As such, any profits from the disposal of our ordinary shares would not ordinarily be taxable in Singapore. However, there are no specific laws or regulations which deal with the characterization of whether a gain is income or capital in nature. If the gains from the disposal of ordinary shares are construed to be of an income nature (which could be the case if, for instance, the gains arise from activities which the IRAS regards as carrying on a trade or business in Singapore), the disposal profits would be taxable as income rather than capital gains. As the precise status of each prospective investor will vary from one another, each prospective investor should consult an independent tax advisor on the Singapore income tax and other tax consequences that will apply to their individual circumstances.

Subject to certain conditions being satisfied, gains derived by a company from the disposal of our ordinary shares between the period of June 1, 2012 and December 31, 2027 (inclusive of both dates) will not be subject to Singapore income tax, if the divesting company holds a minimum shareholding of 20% of our ordinary shares and these shares have been held for a continuous minimum period of 24 months. For disposals during the period from June 1, 2012 and May 31, 2022 (inclusive of both dates), this exemption would not apply to the disposal of unlisted shares in a company that is in the business of trading or holding immovable properties in Singapore (excluding property development). For disposals during the period from June 1, 2022 and December 31, 2027 (inclusive of both dates), this exemption would not apply to the disposal of unlisted shares in a company that is in the business of trading, holding or developing immovable properties in Singapore or abroad.

S-35

In addition, shareholders who apply, or who are required to apply, the Singapore Financial Reporting Standard 39 (“FRS 39”), Financial Reporting Standard 109 (“FRS 109”) or Singapore Financial Reporting Standard (International) 9 (Financial Instruments) (“SFRS(I) 9”) (as the case may be), for the purposes of Singapore income tax may be required to recognize gains or losses (not being gains or losses in the nature of capital) in accordance with the provisions of FRS 39, FRS 109 or SFRS(I) 9 (as modified by the applicable provisions of Singapore income tax law) even though no sale or disposal of our ordinary shares is made. Singapore corporate shareholders who may be subject to such tax treatment should consult their own accounting and tax advisors regarding the Singapore income tax consequences of their acquisition, holding and disposal of our ordinary shares.

Stamp Duty

There is no Singapore stamp duty payable in respect of the issuance or holding of our ordinary shares. Singapore stamp duty will be payable if there is an instrument of transfer of our ordinary shares executed in Singapore or if there is an instrument of transfer executed outside of Singapore which is received in Singapore. Under Singapore law, stamp duty is not applicable to electronic transfers of our shares effected on a book entry basis outside Singapore. We therefore expect that no Singapore stamp duty will be payable in respect of ordinary shares purchased by U.S. holders in this offering assuming that they are acquired solely in book entry form through the facility outside Singapore established by our transfer agent and registrar outside Singapore.

Where shares evidenced in certificated form are transferred and an instrument of transfer is executed (whether physically or in the form of an electronic instrument) in Singapore or outside Singapore and which is received in Singapore, Singapore stamp duty is payable on the instrument of transfer for the sale of our ordinary shares at the rate of 0.2% of the consideration for, or market value of, the transferred shares, whichever is higher. The Singapore stamp duty is borne by the purchaser unless there is an agreement to the contrary. Where the instrument of transfer is executed outside of Singapore and is received in Singapore, Singapore stamp duty must be paid within 30 days of receipt of the instrument of transfer in Singapore. Electronic instruments that are executed outside Singapore are treated as received in Singapore in any of the following scenarios: (a) it is retrieved or accessed by a person in Singapore; (b) an electronic copy of it is stored on a device (including a computer) and brought into Singapore; or (c) an electronic copy of it is stored on a computer in Singapore. Where the instrument of transfer is executed in Singapore, Singapore stamp duty must be paid within 14 days of the execution of the instrument of transfer.

Goods and Services Tax

The issue or transfer of ownership of our ordinary shares would be exempt from Singapore goods and services tax, or GST. Hence, no GST would be incurred on the subscription or subsequent transfer of our ordinary shares.

The sale of our ordinary shares by a GST-registered investor belonging in Singapore for GST purposes to another person belonging in Singapore is an exempt supply not subject to GST. Any input GST incurred by the

GST-registered investor in making the exempt supply is generally not recoverable from the Singapore Comptroller of GST.

Where our ordinary shares are sold by a GST-registered investor in the course of or furtherance of a business carried on by such investor contractually to and for the direct benefit of a person belonging outside Singapore, the sale should generally, subject to satisfaction of certain conditions, be considered a taxable supply subject to GST at 0%. Subject to the normal rules for input tax claims, any input GST incurred by the GST-registered investor in making such a supply in the course of or furtherance of a business carried out by such investor may be fully recoverable from the Singapore Comptroller of GST.

S-36

Each prospective investor should consult an independent tax advisor on the recoverability of input GST incurred on expenses in connection with the purchase and sale of our ordinary shares if applicable.

Services consisting of arranging, brokering, underwriting or advising on the issue, allotment or transfer of ownership of our ordinary shares rendered by a GST-registered person to an investor belonging in Singapore for GST purposes in connection with the investor’s purchase, sale or holding of our ordinary shares will be subject to GST at the current standard rate of 9%. Similar services rendered by a GST-registered person contractually to and for the direct benefit of an investor belonging outside Singapore should generally, subject to the satisfaction of certain conditions, be subject to GST at 0%.

With the implementation of reverse charge from January 1, 2020, the “directly benefit” condition for zero-rating (i.e. GST at 0%) will be amended to allow the zero-rating of a supply of services to the extent that the services directly benefit a person belonging outside Singapore or a GST-registered person in Singapore. Under the reverse charge regime, a GST-registered partially exempt business that is not entitled to full input tax claims will be required to account for GST on all services that it procures from overseas suppliers (except for certain services which are specifically exempt from reverse charge) and the import of low-value goods. A non GST-registered person whose total value of imported services and low-value goods for a 12-month period exceeds S$1 million and is not entitled to full input tax claims even if such person was GST-registered may become liable for GST registration and be required to account for GST both on its taxable supplies and imported services and low-value goods subject to reverse charge.

Estate Duty

Singapore estate duty has been abolished with effect from February 15, 2008 in relation to the estate of any person whose death has occurred on or after February 15, 2008.

Tax Treaties Regarding Withholding Taxes

There is currently no comprehensive avoidance of double taxation agreement between the United States and Singapore which applies to withholding taxes on dividends or capital gains.

UNDERWRITING

We are offering the ordinary shares and pre-funded warrants described in this prospectus supplement through a number of underwriters. J.P. Morgan Securities LLC and Leerink Partners LLC (the “Representatives”) are acting as joint book-running managers of the offering and as representatives of the underwriters. We have entered into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of ordinary shares and pre-funded warrants listed next to its name in the following table:

The underwriters are committed to purchase all the ordinary shares and pre-funded warrants offered by us if they purchase any ordinary shares or pre-funded warrants. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the ordinary shares and pre-funded warrants directly to the public at the initial public offering prices set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $     per ordinary share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $     per ordinary share from the initial public offering price. After the initial offering of the ordinary shares to the public, if all of the ordinary shares are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms. Sales of any ordinary shares or pre-funded warrants made outside of the United States may be made by affiliates of the underwriters.

The underwriters have an option to buy up to      additional ordinary shares from us to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per ordinary share or pre-funded warrant less the amount paid by the underwriters to us per ordinary share or pre-funded warrant. The underwriting fee is $     per ordinary share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

S-38

We estimate that the total expenses of this offering, including printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $     .

A prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

For 60 days after the date of this prospectus supplement (the “Lock-up Period”), without first obtaining the written consent of the Representatives, we have agreed that we will not (i) sell, offer to sell, contract to sell or lend any ordinary shares or Related Securities (as defined below); (ii) effect any short sale, or establish or increase any “put equivalent position” (as defined in Rule 16a-1(h) under the Exchange Act) or liquidate or decrease any “call equivalent position” (as defined in Rule 16a-1(b) under the Exchange Act) of any ordinary shares or Related Securities; (iii) pledge, hypothecate or grant any security interest in any ordinary shares or Related Securities; (iv) in any other way transfer or dispose of any ordinary shares or Related Securities; (v) enter into any swap, hedge or similar arrangement or agreement that transfers, in whole or in part, the economic risk of ownership of any ordinary shares or Related Securities, regardless of whether any such transaction is to be settled in securities, in cash or otherwise; (vi) announce the offering of any ordinary shares or Related Securities; (vii) file any registration statement under the Securities Act in respect of any ordinary shares or Related Securities (other than as contemplated by this prospectus supplement); or (viii) publicly announce the intention to do any of the foregoing; provided, however, that we may (A) effect the transactions contemplated herein, (B) issue ordinary shares, options or other rights to receive or purchase or, or issue ordinary shares upon exercise of options or vesting of restricted share units or performance share units, pursuant to any share or stock option, share or stock bonus or other share or stock plan or arrangement incorporated by reference into this prospectus supplement provided that any directors or officers who are recipients thereof have provided to the Representatives a signed lock-up agreement, (C) file a registration statement on Form S-8 to register ordinary shares issuable pursuant to the terms of a stock option, stock bonus or other stock plan or arrangement incorporated by reference into this prospectus supplement or any amendment to any such plan or arrangement and (D) issue ordinary shares or Related Securities, or enter into an agreement to issue ordinary shares or Related Securities, in connection with any merger, joint venture, strategic alliances, commercial or other collaborative transaction or the acquisition or license of the business, property, technology or other assets of another individual or entity or the assumption of an employee benefit plan in connection with a merger or acquisition; provided that the aggregate number of ordinary shares or Related Securities that we may issue or agree to issue pursuant to this clause (D) shall not exceed 7% of our total outstanding share capital immediately following the issuance of the securities offered in connection with this prospectus supplement; and provided further that the recipients thereof provide to the Representatives a signed lock-up agreement.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling ordinary shares in the open market for the purpose of preventing or retarding a decline in the market price of the ordinary shares while this offering is in progress. These stabilizing transactions may include making short sales of ordinary shares, which involves the sale by the underwriters of a greater number of ordinary shares than they are required to purchase in this offering, and purchasing ordinary shares on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional ordinary shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional ordinary shares, in whole or in part, or by purchasing ordinary shares in the open market. In making this determination, the underwriters will consider, among other things, the price of ordinary shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional ordinary shares. A naked short position is more likely to be created if the underwriters are concerned that there

S-41

may be downward pressure on the price of the ordinary shares in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase ordinary shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act of 1933, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the ordinary shares, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase ordinary shares in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the ordinary shares or preventing or retarding a decline in the market price of the ordinary shares, and, as a result, the price of the ordinary shares may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the Nasdaq Global Market, in the over-the-counter market or otherwise.

Certain of the underwriters and their affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

RISK FACTORS

Investing in our securities involves significant risk. The prospectus supplement applicable to each offering of our securities may contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under the heading “Risk Factors” included in our most recent annual report on Form 10-K, as revised or supplemented by our subsequent quarterly reports on Form 10-Q or our current reports on Form 8-K on file with the SEC, all of which are incorporated herein by reference, and which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the documents we have filed with the SEC that are incorporated by reference contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended, that involve substantial risks and uncertainties that relate to future events or to our future operations or financial performance. In some cases, forward-looking statements are identified by the words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “future,” “goals,” “intend,” “likely,” “may,” “might,” “ongoing,” “objective,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “strategy,” “target,” “will” and “would” or the negative of these terms, or other comparable terminology intended to identify statements about the future, although not all forward-looking statements contain these identifying words. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements.

Although we believe that we have a reasonable basis for each forward-looking statement contained in this prospectus, any accompanying prospectus and the documents that we have filed with the SEC that are incorporated by reference, such statements are based on a combination of facts and factors currently known by us and our expectations of the future, about which we cannot be certain. Forward-looking statements include statements about:

7

You should refer to the section titled “Risk Factors” of this prospectus and in our other filings with the SEC for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure that the forward-looking statements in this prospectus, any accompanying prospectus or the documents we have filed with the SEC that are incorporated by reference will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, these statements should not be regarded as representations or warranties by us or any other person that we will achieve our objectives and plans in any specified time frame, or at all. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements as predictions of future events.

You should read this prospectus, any accompanying prospectus supplement, the documents that we have incorporated by reference herein and therein and the documents we have filed as exhibits to the registration statement, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

INDUSTRY AND MARKET DATA

Certain industry data and market data included in this prospectus, any accompanying prospectus supplement and the documents we have filed with the SEC that are incorporated herein by reference were obtained from independent third-party surveys, market research, publicly available information, reports of governmental agencies and industry publications and surveys. All of management’s estimates presented herein are based upon management’s review of independent third-party surveys and industry publications prepared by a number of sources and other publicly available information. All of the market data used in this prospectus, any accompanying prospectus supplement and the documents we have filed with the SEC that are incorporated herein by reference involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. We believe that the information from these industry publications and surveys is reliable. The industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the section titled “Risk Factors.” These and other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by us.

RATIO OF EARNINGS TO FIXED CHARGES

Any time debt securities are offered pursuant to this prospectus, we will provide a table setting forth our ratio of earnings to fixed charges on a historical basis in the applicable prospectus supplement, if required.

9

USE OF PROCEEDS

We cannot assure you that we will receive any proceeds in connection with securities which may be offered pursuant to this prospectus. Unless otherwise indicated in the applicable prospectus supplement, we intend to use the net proceeds from the sale of securities under this prospectus for our operations and for other general corporate purposes, including, but not limited to, clinical trial costs and other research and development expenses; continued investment in our drug development platform; and working capital, capital expenditures and general and administrative expenses. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures. As a result, our management will have broad discretion to allocate the net proceeds, if any, we receive in connection with securities offered pursuant to this prospectus for any purpose. Pending application of the net proceeds as described above, we may initially invest the net proceeds in short-term, investment-grade, interest-bearing securities or apply them to the reduction of short-term indebtedness.

DESCRIPTION OF SHARE CAPITAL

General

For the purposes of this section, references to “shareholders” mean those persons whose names and number of shares are entered in our register of members. Only persons who are registered in our register of members are recognized under Singapore law as shareholders of our company with legal standing to institute shareholder actions against us or otherwise seek to enforce their rights as shareholders. Our branch register of members is maintained by our transfer agent, Computershare Trust Company, N.A., or Computershare.

The shares offered in any offering pursuant to this prospectus and any accompanying prospectus supplement are expected to be held through the Depository Trust Company, or DTC. Accordingly, DTC or its nominee, Cede & Co., will be the shareholder on record registered in our register of members. The holder of our shares held in book-entry through DTC or its nominee may become a registered shareholder by exchanging its interest in our shares for certificated shares and being registered in our register of members for such shares. The procedures by which a holder of book-entry interests held through DTC or its nominee may exchange such interests for certificated shares are determined by DTC and Computershare, in accordance with their internal policies and guidelines regulating the withdrawal and exchange of book-entry interests for certificated shares, and following such an exchange Computershare will perform the procedures to register the shares in the register.

Under the Companies Act 1967 of Singapore (“Singapore Companies Act”), if (a) the name of any person is without sufficient cause entered in or omitted from the register of members; or (b) default is made or there is unnecessary delay in entering in the register of members the fact of any person having ceased to be a member, the person aggrieved or any member of the public company or the company itself, may apply to the Singapore courts for rectification of the register of members. The Singapore courts may either refuse the application or order rectification of the register of members, and may direct the company to pay any damages sustained by any party to the application. The Singapore courts will not entertain any application for the rectification of a register of members in respect of an entry which was made in the register of members more than 30 years before the date of the application.

As of December 31, 2021, there were outstanding:

The following description of our share capital and provisions of our constitution (formerly known as our memorandum and articles of association) are summaries and are qualified by reference to the Singapore Companies Act and our constitution. A copy of our constitution has been filed with the SEC as an exhibit to the registration statement of which this prospectus forms a part.

Ordinary Shares

As of December 31, 2021, our issued and paid-up ordinary share capital consists of 59,841,116 ordinary shares. We currently have only one class of issued ordinary shares, which have identical rights in all respects and rank equally with one another. Our ordinary shares have no par value and there is no authorized share capital

11

under Singapore law. There is a provision in our constitution which provides that we may issue shares with such preferred, deferred or other special rights or such restrictions, whether in regard to dividend, voting, return of capital or otherwise as our board of directors may determine.

All of our shares presently issued are fully paid-up, and existing shareholders are not subject to any calls on these shares. Although Singapore law does not recognize the concept of “non-assessability” with respect to newly-issued shares, we note that any purchaser of our shares who has fully paid up all amounts due with respect to such shares will not be subject under Singapore law to any personal liability to contribute to the assets or liabilities of our company in such purchaser’s capacity solely as a holder of such shares. We believe that this interpretation is substantively consistent with the concept of “non-assessability” under most, if not all, U.S. state corporation laws. All of our shares are in registered form. We cannot, except in the circumstances permitted by the Singapore Companies Act, grant any financial assistance for the acquisition or proposed acquisition of our own shares. Except as described below under “—Takeovers,” there are no limitations imposed by the Singapore Companies Act or by our constitution on the right of shareholders not resident in Singapore to hold or vote ordinary shares.

Transfer Agent and Registrar

The transfer agent and registrar for our ordinary shares is Computershare Trust Company, N.A.

Nasdaq Global Market

Our ordinary shares are listed for quotation on The Nasdaq Global Market under the symbol “WVE.”

New Shares

Under the Singapore Companies Act, new shares may be issued only with the prior approval of our shareholders in a general meeting. General approval may be sought from our shareholders in a general meeting for the issue of shares. Approval, if granted, will lapse at the earlier of:

but any approval may be revoked or varied by the company in a general meeting.

Our shareholders have provided such general authority to issue new ordinary shares until the conclusion of our 2022 annual general meeting. Such approval will lapse in accordance with the preceding paragraph if our shareholders do not grant a new approval at our 2022 annual general meeting. Subject to this and the provisions of the Singapore Companies Act and our constitution, our board of directors may allot and issue or grant options over or otherwise dispose of new ordinary shares to such persons on such terms and conditions and with the rights and restrictions as they may think fit to impose.

Preferred Shares

Series A Preferred Shares

As of December 31, 2021, we have 3,901,348 Series A preferred shares outstanding. These shares are currently held by one of our largest shareholders, Shin Nippon Biomedical Laboratories, Ltd. The terms of the Series A preferred shares as set out in our constitution include (1) no voting rights at any general meeting other than in limited circumstances, (2) a liquidation preference equal to $0.002 per Series A preferred share, (3) no entitlement to dividends and (4) the right to convert the Series A preferred shares at any time on a one-for-one basis into ordinary shares at the discretion of the holder in accordance with the constitution.

12

The holders of the Series A preferred shares are not entitled to vote at any general meeting. The only instances in which the holders of the Series A preferred shares are able to vote at a general meeting would be if (but only if) the matters to be discussed at the meeting relate to or there is intent to pass resolutions on (i) abrogating or changing the rights attached to the Series A preferred shares; and (ii) for the winding up of the Company. Such resolutions would require the unanimous approval of the holders of the Series A preferred shares.

Other Preferred Shares

Under the Singapore Companies Act, different classes of shares in a public company may be issued only if (a) the issue of the class or classes of shares is provided for in the constitution of the public company and (b) the constitution of the public company sets out in respect of each class of shares the rights attached to that class of shares. Our constitution provides that we may issue shares of a different class with preferred, deferred or other special rights, or such restrictions, whether in regard to dividend, voting, return of capital or otherwise as our board of directors may determine. Under Singapore law, our preferred shareholders will have the right to attend any general meeting and in a poll at such general meeting, to have at least one vote for every preferred share held:

We may, subject to the Singapore Companies Act and the prior approval in a general meeting of our shareholders, issue preferred shares which are, or at our option or are to be, subject to redemption provided that such preferred shares may not be redeemed out of capital unless:

Further, such shares must be fully paid-up before they are redeemed.

As of the date of this prospectus, we have no preferred shares outstanding other than the Series A preferred shares described above. At present, we have no plans to issue additional preferred shares.

Registration Rights under our Share Purchase Agreement with Pfizer

Under the terms of our Share Purchase Agreement dated as of May 5, 2016 with an affiliate of Pfizer Inc., or the Pfizer Affiliate, under which the Pfizer Affiliate purchased 1,875,000 ordinary shares from us, or the Pfizer Shares, subject to certain conditions and limitations, we agreed to provide certain demand registration rights to the Pfizer Affiliate in order to register all or a portion of the Pfizer Shares purchased by the Pfizer Affiliate. We also provided the Pfizer Affiliate with certain “piggyback” registration rights, subject to certain conditions and limitations, such that when we propose to register our ordinary shares for our account, the Pfizer Affiliate will have the right to include some or all of the Pfizer Shares in such registration. The Share Purchase Agreement also contains other customary terms and conditions of the parties with respect to the registration of the Pfizer Shares.

13

Registration Rights under our Share Purchase Agreement with Takeda

On February 19, 2018, we entered into a Share Purchase Agreement with Takeda Pharmaceutical Company Limited, or Takeda, pursuant to which Takeda purchased 1,096,892 of our ordinary shares, or the Takeda Shares. In connection with the Share Purchase Agreement, Takeda and we agreed upon certain rights and restrictions as set forth in the Investor Agreement, dated as of April 2, 2018, or the Investor Agreement. The Takeda Shares are subject to a lock-up restriction, such that Takeda will not, and will also cause its affiliates not to, without our prior approval, sell, transfer or otherwise dispose of the Takeda Shares until certain specified periods of time after the effective date of the Investor Agreement. For a certain period following the expiration of the lock-up period, subject to certain conditions and limitations, we agreed to provide certain demand registration rights to Takeda in order to register all or a portion of the Takeda Shares purchased by Takeda. We also provided Takeda with certain “piggyback” registration rights for a certain period following the expiration of the lock-up period, subject to certain conditions and limitations, such that when we propose to register our ordinary shares for our account, Takeda will have the right to include some or all of the Takeda Shares in such registration. The Investor Agreement also contains other customary terms and conditions of the parties with respect to the registration of Takeda Shares.

Transfer of Ordinary Shares

Subject to applicable securities laws in relevant jurisdictions and our constitution, our ordinary shares are freely transferable. Our constitution provides that shares may be transferred by a duly signed instrument of transfer in any usual or common form or in a form approved by the directors and The Nasdaq Stock Market. The directors may decline to register any transfer unless, among other things, evidence of payment of any stamp duty payable with respect to the transfer is provided together with other evidence of ownership and title as the directors may reasonably require to show the right of the transferor to make the transfer. We will replace lost or destroyed certificates for shares upon notice to us and upon, among other things, the applicant furnishing evidence and indemnity as the directors may require and the payment of all applicable fees.

Election and Re-election of Directors

We may, by ordinary resolution, remove any director before the expiration of his or her period of office, notwithstanding anything in our constitution or in any agreement between us and such director. We may also, by an ordinary resolution, appoint another person in place of a director removed from office pursuant to the foregoing.

Under our constitution, subject to the Singapore Companies Act, any director shall retire at the next annual general meeting and shall then be eligible for re-election at that meeting.

Our board of directors shall have the power, at any time and from time to time, to appoint any person to be a director either to fill a casual vacancy or as an additional director so long as the total number of directors shall not at any time exceed the maximum number (if any) fixed by or in accordance with our constitution.

Shareholders’ Meetings

We are required to hold an annual general meeting each calendar year and within six months after the end of each financial year. The directors may convene an extraordinary general meeting whenever they think fit and they must do so upon the written request of shareholders holding not less than 10% of the total number of paid-up shares as of the date of deposit of the requisition carrying the right to vote at a general meeting. In addition, two or more shareholders holding not less than 10% of our total number of issued shares (excluding our treasury shares) may call a meeting of our shareholders.

The Singapore Companies Act provides that a shareholder is entitled to attend any general meeting and speak on any resolution put before the general meeting. Unless otherwise required by law or by our constitution,

14

resolutions put forth at general meetings may be decided by ordinary resolution, requiring the affirmative vote of a majority of the shareholders present in person or represented by proxy at the meeting and entitled to vote on the resolution. An ordinary resolution suffices, for example, for appointments of directors. A special resolution, requiring an affirmative vote of not less than three-fourths of the shareholders present in person or represented by proxy at the meeting and entitled to vote on the resolution, is necessary for certain matters under Singapore law, such as an alteration of our constitution. A shareholder entitled to attend and vote at a meeting of the company, or at a meeting of any class of shareholders of the company, is entitled to appoint another person or persons, whether a shareholder of the company or not, as the shareholder’s proxy to attend and vote instead of the shareholder at the meeting. Under the Singapore Companies Act, a proxy appointed to attend and vote instead of the shareholder also has the same right as the shareholder to speak at the meeting, but unless the constitution of the company otherwise provides, (i) a proxy is not entitled to vote except on a poll, (ii) a shareholder is not entitled to appoint more than two proxies to attend and vote at the same meeting and (iii) where a shareholder appoints two proxies the appointments are invalid unless the shareholder specifies the proportions of the shareholder’s holdings to be represented by each proxy.

Notwithstanding the foregoing, a registered shareholder entitled to attend and vote at a meeting of the company held pursuant to an order of court under Section 210(1) of the Singapore Companies Act, or at any adjourned meeting under Section 210(3) of the Singapore Companies Act, is, unless the court orders otherwise, entitled to appoint only one proxy to attend and vote at the same meeting, and except where the aforementioned applies, a registered shareholder having a share capital who is a relevant intermediary (as defined under the Singapore Companies Act) may appoint more than two proxies in relation to a meeting to exercise all or any of the shareholder’s rights to attend and to speak and vote at the meeting, but each proxy must be appointed to exercise the rights attached to a different share or shares held by the shareholder (which number and class of shares shall be specified), and at such meeting, the proxy has the right to vote on a show of hands.

Only registered shareholders of our company, and their proxies, will be entitled to attend, speak and vote at any meeting of shareholders. Under the Singapore Companies Act, public companies may issue non-voting shares and shares that confer special, limited or conditional voting rights, such that the holder of a share may vote on a resolution before a general meeting of the company if, in accordance with the provisions of Section 64A of the Singapore Companies Act, the share confers on the holder a right to vote on that resolution.

Voting Rights

As provided under our constitution and the Singapore Companies Act, voting at any meeting of shareholders is by show of hands unless a poll has been demanded prior to the declaration of the result of the show of hands by, among others, (i) the chairman or (ii) at least one shareholder present in person or by proxy or by attorney or, in the case of a corporation, by a representative entitled to vote thereat, in each case representing in the aggregate not less than 5% of the total voting rights of all shareholders having the right to vote at the general meeting, provided that no poll shall be demanded in respect of an election of a chairman or relating to any adjournment of such meeting. On a poll every shareholder who is present in person or by proxy or by attorney, or in the case of a corporation, by a representative, has one vote for every share held by such shareholder. Proxies need not be shareholders.

Only those shareholders who are registered in our register of members as holders of ordinary shares will be entitled to vote at any meeting of shareholders. Therefore, DTC, or its nominee, will grant an omnibus proxy to DTC participants holding our shares in book-entry form through a broker, bank, nominee, or other institution that is a direct or indirect participant in the DTC. Such shareholders will have the right to instruct their broker, bank, nominee or other institution holding these shares on how to vote such shares by completing the voting instruction form provided by the applicable broker, bank, nominee, or other institution. Whether voting is by a show of hands or by a poll, DTC’s vote will be voted by the chairman of the meeting according to the results of the DTC’s participants’ votes (which results will reflect the instructions received from shareholders that own our shares electronically in book-entry form).

15

Minority Rights

The rights of minority shareholders of Singapore companies are protected, among other things, under Section 216 of the Singapore Companies Act, which gives the Singapore courts a general power to make any order, upon application by any shareholder of a company, as they think fit to remedy any of the following situations:

Singapore courts have wide discretion as to the remedy they may grant, and the remedies listed in the Singapore Companies Act itself are not exclusive. In general, Singapore courts may, with a view to bringing to an end or remedying the matters complained of:

Dividends

Subject to any preferential rights of holders of any outstanding preferred shares, holders of our ordinary shares will be entitled to receive dividends and other distributions in cash, shares or property as may be declared by our company from time to time. We may, by ordinary resolution, declare dividends at a general meeting of shareholders, but we are restricted from paying dividends in excess of the amount recommended by our board of directors. Pursuant to Singapore law and our constitution, no dividend may be paid except out of our profits. To date, we have not declared any cash dividends on our ordinary shares and have no current plans to pay cash dividends in the foreseeable future.

Bonus and Rights Issues

In a general meeting, our shareholders may, upon the recommendation of the directors, capitalize any reserves or profits and distribute them as bonus shares, credited as paid-up, to the shareholders in proportion to their shareholdings.

Subject to the provisions of the Singapore Companies Act and our constitution, our directors may also issue rights to take up additional ordinary shares to our shareholders in proportion to their respective ownership. Such rights are subject to any condition attached to such issue and the regulations of any stock exchange on which our shares are listed, as well as U.S. federal and blue sky securities laws applicable to such issue.

Takeovers

The Singapore Code on Take-overs and Mergers applies to, among other things, the acquisition of voting shares of Singapore-incorporated listed public companies or unlisted public companies with more than 50

16

shareholders and net tangible assets of S$5 million or more. Any person acquiring, whether by a series of transactions over a period of time or not, either on his or her own or together with parties acting in concert with such person, 30% or more of our voting shares, or, if such person holds, either on his or her own or together with parties acting in concert with such person, between 30% and 50% (both amounts inclusive) of our voting shares, and if such person (or parties acting in concert with such person) acquires additional voting shares representing more than 1% of our voting shares in any six-month period, must, except with the consent of the Securities Industry Council in Singapore, extend a mandatory takeover offer for the remaining voting shares in accordance with the provisions of the Singapore Code on Take-overs and Mergers. Responsibility for ensuring compliance with the Singapore Code on Take-overs and Mergers rests with parties (including company directors) to a take-over or merger and their advisors.

“Parties acting in concert” comprise individuals or companies who, pursuant to an agreement or understanding (whether formal or informal), cooperate, through the acquisition by any of them of shares in a company, to obtain or consolidate effective control of that company. Certain persons are presumed (unless the presumption is rebutted) to be acting in concert with each other. They are as follows:

Subject to certain exceptions, a mandatory offer must be in cash or be accompanied by a cash alternative at not less than the highest price paid by the offeror or parties acting in concert with the offeror during the offer period and within the six months prior to its commencement.

Under the Singapore Code on Take-overs and Mergers, where effective control of a company is acquired or consolidated by a person, or persons acting in concert, a general offer to all other shareholders is normally required. An offeror must treat all shareholders of the same class in an offeree company equally. A fundamental requirement is that shareholders in the company subject to the takeover offer must be given sufficient information, advice and time to consider and decide on the offer. These legal requirements may impede or delay a takeover of our company by a third-party.

17

We may submit an application to the Securities Industry Council of Singapore for a waiver from the Singapore Code on Take-overs and Mergers so that the Singapore Code on Take-overs and Mergers will not apply to our company for so long as we are not listed on a securities exchange in Singapore. We will make an appropriate announcement if we submit the application and when the result of the application is known.

Liquidation or Other Return of Capital

On a winding-up or other return of capital, subject to any special rights attaching to the Series A preferred shares or to any other class of shares, holders of ordinary shares will be entitled to participate in any surplus assets in proportion to their shareholdings.

Limitations of Liability and Indemnification Matters

Under Section 172 of the Singapore Companies Act, any provision exempting or indemnifying the officers of a company (including directors) against any liability that would otherwise attach to them in connection with any negligence, default, breach of duty or breach of trust in relation to the company is void. However, a company is not prohibited from (a) purchasing and maintaining for any such individual insurance against liability incurred by him or her in connection with any negligence, default, breach of duty or breach of trust in relation to the company, or (b) indemnifying the individual against liability incurred by him or her to a person other than the company except when the indemnity is against any liability (i) of the individual to pay a fine in criminal proceedings, (ii) of the individual to pay a penalty in respect of non-compliance with any requirements of a regulatory nature (howsoever arising), (iii) incurred by the individual in defending criminal proceedings in which he or she is convicted, (iv) incurred by the individual in defending civil proceedings brought by the company or a related company in which judgment is given against him or her, or (v) incurred by the individual in connection with an application for relief under Section 76A(13) or Section 391 of the Singapore Companies Act in which the court refuses to grant him or her relief.

Subject to the Singapore Companies Act and every other Singapore statute for the time being in force concerning companies and affecting us, our constitution provides that each of our directors and other officers and those of our subsidiaries and affiliates shall be entitled to be indemnified by us or such subsidiary against any liability incurred by him or her arising out of or in connection with any acts, omissions or conduct, actual or alleged, by such individual acting in his or her capacity as either director, officer, secretary or employee of us or the relevant subsidiary, except to such extent as would not be permitted under applicable Singapore laws or which would otherwise result in such indemnity being void in accordance with the provisions of the Singapore Companies Act.

Subject to the Singapore Companies Act and every other Singapore statute for the time being in force and affecting our company, we may indemnify our directors and officers against costs, charges, fees and other expenses that may be incurred by any of them in defending any proceedings (whether civil or criminal) relating to anything done or omitted or alleged to be done or omitted by such person acting in his or her capacity as a director, officer or employee of our company, in which judgment is given in his or her favor, or in which he or she is acquitted or in which the courts have granted relief pursuant to the provisions of the Singapore Companies Act, provided that such indemnity shall not extend to any liability which by law would otherwise attach to him or her in respect of any negligence, default, breach of duty or breach of trust of which he may be guilty in relation to our company, or which would otherwise result in such indemnity being voided under applicable Singapore laws.

No director or officer of our company shall be liable for any acts, omissions, neglects, defaults or other conduct of any other director or officer, and to the extent permitted by Singapore law, our company shall contribute to the amount paid or payable by a director or officer in such proportion as is appropriate to reflect the relative fault of such director or officer, taking into consideration any other relevant equitable considerations, including acts of other directors or officers and our company, and the relative fault of such parties in respect thereof.

18

In addition, subject to the Singapore Companies Act and every other Singapore statute for the time being in force and affecting our company, no director, managing director or other officer shall be liable for the acts, receipts, neglects or defaults of any other director or officer, or for joining in any receipt or other act for conformity, or for any loss or expense incurred by us, through the insufficiency or deficiency of title to any property acquired by order of the directors for us or for the insufficiency or deficiency of any security upon which any of our moneys are invested or for any loss or damage arising from the bankruptcy, insolvency or tortious act of any person with whom any moneys, securities or effects are deposited, or any other loss, damage or misfortune which happens in the execution of his or her duties, unless the same happens through his or her own negligence, default, breach of duty or breach of trust.

We have entered into deeds of indemnity with each of our directors and officers. These agreements will require us to indemnify these individuals to the fullest extent permitted under our constitution and the Singapore Companies Act against liabilities that may arise by reason of their service to us as a director or officer of the company (as the case may be), and to advance expenses incurred in connection with any proceeding against them by reason of their status as a director, officer, agent or employee of the company in accordance with the terms of the deeds. These indemnification rights shall not be exclusive of any other right which an indemnified person may have or thereafter acquire under any applicable law, provision of our constitution, agreement, vote of shareholders or disinterested directors or otherwise.

We expect to maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers.

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we include in any applicable prospectus supplements, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future debt securities we may offer pursuant to this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. If we so indicate in a prospectus supplement, the terms of any debt securities offered under such prospectus supplement may differ from the terms we describe below, and to the extent the terms set forth in a prospectus supplement differ from the terms described below, the terms set forth in the prospectus supplement shall control.

We may sell from time to time, in one or more offerings under this prospectus, debt securities, which may be senior or subordinated. We will issue any such senior debt securities under a senior indenture that we will enter into with a trustee to be named in the senior indenture. We will issue any such subordinated debt securities under a subordinated indenture, which we will enter into with a trustee to be named in the subordinated indenture. We have filed forms of these documents as exhibits to the registration statement, of which this prospectus is a part. We use the term “indentures” to refer to either the senior indenture or the subordinated indenture, as applicable. The indentures will be qualified under the Trust Indenture Act of 1939, as in effect on the date of the indenture, or the Trust Indenture Act. We use the term “debenture trustee” to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities.

General

Each indenture provides that debt securities may be issued from time to time in one or more series and may be denominated and payable in foreign currencies or units based on or relating to foreign currencies. Neither indenture limits the amount of debt securities that may be issued thereunder, and each indenture provides that the specific terms of any series of debt securities shall be set forth in, or determined pursuant to, an authorizing resolution and/or a supplemental indenture, if any, relating to such series.

We will describe in each prospectus supplement the following terms relating to a series of debt securities:

20

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the U.S. federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

Conversion or Exchange Rights

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

Consolidation, Merger or Sale; No Protection in the Event of a Change of Control or Highly Leveraged Transaction

The indentures do not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate.

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

Events of Default Under the Indenture

The following are events of default under the indentures with respect to any series of debt securities that we may issue:

21

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

If an event of default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than a majority in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the debenture trustee if given by the holders), declare to be due and payable immediately the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) of and premium, if any, and accrued and unpaid interest, if any, on all debt securities of that series. Before a judgment or decree for payment of the money due has been obtained with respect to debt securities of any series, the holders of a majority in principal amount of the outstanding debt securities of that series (or, at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal, premium, if any, and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the applicable indenture (including payments or deposits in respect of principal, premium or interest that had become due other than as a result of such acceleration). We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an event of default.

Subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the debenture trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the debenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the debenture trustee, or exercising any trust or power conferred on the debenture trustee, with respect to the debt securities of that series, provided that:

A holder of the debt securities of any series will only have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies if:

22

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the applicable debenture trustee regarding our compliance with specified covenants in the applicable indenture.

Modification of Indenture; Waiver

The debenture trustee and we may change the applicable indenture without the consent of any holders with respect to specific matters, including:

In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the debenture trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series (or, at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) that is affected. However, the debenture trustee and we may make the following changes only with the consent of each holder of any outstanding debt securities affected:

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series (or, at a meeting of holders of such series at which a quorum is present, the holders of a majority in principal amount of the debt securities of such series represented at such meeting) may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any debt security of that series or in respect of a covenant or provision, which cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

23

Discharge

Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for obligations to:

In order to exercise our rights to be discharged with respect to a series, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, the premium, if any, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange, and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, DTC or another depositary named by us and identified in a prospectus supplement with respect to that series.

At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange or in the applicable indenture, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

24

Information Concerning the Debenture Trustee

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

Payment and Paying Agents

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

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

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

Governing Law

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

Subordination of Subordinated Debt Securities

Our obligations pursuant to any subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of senior indebtedness we may incur. It also does not limit us from issuing any other secured or unsecured debt.

25

DESCRIPTION OF WARRANTS

DESCRIPTION OF RIGHTS

General

We may issue rights to our shareholders to purchase our ordinary shares or the other securities described in this prospectus. We may offer rights separately or together with one or more additional rights, debt securities, ordinary shares or warrants, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent. The rights agent will act solely as our agent in connection with the certificates relating to the rights of the series of certificates and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights. The following description sets forth certain general terms and provisions of the rights to which any prospectus supplement may relate. The particular terms of the rights to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the rights so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the rights, rights agreement or rights certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable rights agreement and rights certificate for additional information before you decide whether to purchase any of our rights.

We will provide in a prospectus supplement the following terms of the rights being issued:

Each right will entitle the holder of rights to purchase for cash the principal amount of our ordinary shares or other securities at the exercise price provided in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement.

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or

27

any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the ordinary shares or other securities, as applicable, purchasable upon exercise of the rights. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

Rights Agent

The rights agent for any rights we offer will be set forth in the applicable prospectus supplement.

28

DESCRIPTION OF UNITS

The following description, together with the additional information that we include in any applicable prospectus supplements summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

We will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, as well as any related free writing prospectuses and the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may issue units consisting of our ordinary shares, one or more debt securities, warrants, or rights for the purchase of our ordinary shares and/or debt securities in one or more series, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each security included in the unit. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

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

The provisions described in this section, as well as those set forth in any prospectus supplement or as described under “Description of Share Capital,” “Description of Debt Securities,” “Description of Warrants” and “Description of Rights” will apply to each unit, as applicable, and to any ordinary shares, debt security, warrant or right included in each unit, as applicable.

Unit Agent

The name and address of the unit agent, if any, for any units we offer will be set forth in the applicable prospectus supplement.

Issuance in Series

We may issue units in such amounts and in such numerous distinct series as we determine.

29

Enforceability of Rights by Holders of Units

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

COMPARISON OF SHAREHOLDER RIGHTS

We are incorporated under the laws of Singapore. The following discussion summarizes material differences between the rights of holders of our ordinary shares and the rights of holders of the common stock of a typical corporation incorporated under the laws of the state of Delaware which result from differences in governing documents and the laws of Singapore and Delaware.

This discussion does not purport to be a complete statement of the rights of holders of our ordinary shares under applicable law in Singapore and our constitution or the rights of holders of the common stock of a typical corporation under applicable Delaware law and a typical certificate of incorporation and bylaws.

PLAN OF DISTRIBUTION

We may offer securities under this prospectus from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities (1) through underwriters or dealers, (2) through agents or (3) directly to one or more purchasers, or through a combination of such methods. We may distribute the securities from time to time in one or more transactions at:

We may directly solicit offers to purchase the securities being offered by this prospectus and may also engage in “at the market” offerings as defined in Rule 415 of the Securities Act. We may also designate agents to solicit offers to purchase the securities from time to time. We will name in a prospectus supplement any underwriter or agent involved in the offer or sale of the securities.

If we utilize a dealer in the sale of the securities being offered by this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale, and we will provide the name of any underwriter in the prospectus supplement which the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of the securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions.

With respect to underwritten public offerings, negotiated transactions and block trades, we will provide in the applicable prospectus supplement information regarding any compensation we pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof.

If so, indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

47

Our ordinary shares sold pursuant to the registration statement of which this prospectus is a part will be authorized for quotation and trading on The Nasdaq Global Market. The applicable prospectus supplement will contain information, where applicable, as to any other listing, if any, on The Nasdaq Global Market or any securities market or other securities exchange of the securities covered by the prospectus supplement. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

In order to facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing the applicable security in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if the securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc., or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

The underwriters, dealers and agents may engage in other transactions with us, or perform other services for us, in the ordinary course of their business.

48

ENFORCEMENT OF CIVIL LIABILITIES UNDER UNITED STATES SECURITIES LAWS

We are incorporated under the laws of the Republic of Singapore, and certain of our officers and directors are residents outside the United States. Moreover, a majority of our consolidated assets are located outside the United States. Although we are incorporated outside the United States, we have agreed to accept service of process in the United States through our agent designated for that purpose. Nevertheless, since a majority of the consolidated assets owned by us are located outside the United States any judgment obtained in the United States against us may not be enforceable within the United States. There is no treaty between the United States and Singapore providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters and a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the federal securities laws, would, therefore, not be automatically enforceable in Singapore.

There is uncertainty as to whether judgments of courts in the United States based upon the civil liability provisions of the federal securities laws of the United States would be recognized or enforceable in Singapore. In making a determination as to enforceability of a judgment of the courts of the United States, and subject to the Singapore courts having jurisdiction over the judgment debtor, the Singapore courts would have regard to whether the judgment was final and conclusive and on the merits of the case, given by a court of law of competent jurisdiction, and was expressed to be for a fixed sum of money. In general, an in personam foreign judgment that is final and conclusive (that is, in general, a judgment that makes a final determination of rights between the parties and cannot be re-opened or altered by the court that delivered it, or be overridden by another body not being an appellate or supervisory body, although it may be subject to an appeal), given by a competent court of law having jurisdiction over the parties subject to such judgment, and for a fixed and ascertainable sum of money, may be enforceable as a debt in the Singapore courts under common law unless procured by fraud, or the proceedings in which such judgments were obtained were not conducted in accordance with principles of natural justice, or the enforcement thereof would be contrary to fundamental public policy, or if the judgment would conflict with earlier judgment(s) from Singapore or earlier foreign judgment(s) recognized in Singapore, or if the judgment would amount to the direct or indirect enforcement of foreign penal, revenue or other public laws (save where any such component of the judgment can be duly severed from the rest of the judgment sought to be enforced). Civil liability provisions of the federal and state securities law of the United States permit the award of punitive damages against us, our directors and officers. Singapore courts would not recognize or enforce judgments against us, our directors and officers to the extent that doing so would amount to the direct or indirect enforcement of foreign penal, revenue or other public laws. It is uncertain as to whether a judgment of the courts of the United States under civil liability provisions of the federal securities law of the United States would be regarded by the Singapore courts as being pursuant to foreign, penal, revenue or other public laws. Such a determination has yet to be made by a Singapore court in a reported decision.

In addition, holders of book-entry interests in our shares will be required to exchange such interests for certificated shares and to be registered as shareholders in our shareholder register in order to have standing to bring a shareholder suit and, if successful, to enforce a foreign judgment against us, our directors or our executive officers in the Singapore courts.

A holder of book-entry interests in our shares may become a registered shareholder of our company by exchanging such holder’s interest in our shares for certificated shares and being registered in our shareholder register. The administrative process of becoming a registered shareholder could result in delays prejudicial to any legal proceeding or enforcement action.
