Evaxion Biotech A/S (EVAX) 424B5Prospectus supplement for primary offering

This prospectus supplement and the accompanying prospectus are part of a registration statement on Form F-3 that we have filed with the Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under this shelf registration process, we may offer our securities as described in our base prospectus included in the shelf registration statement in one or more offerings up to a total aggregate offering price of $100,000,000. The $14,439,000 of our ordinary shares represented by ADSs that may be offered, issued and sold under this prospectus supplement is included in the $100,000,000 of securities that may be offered, issued and sold by us pursuant to our shelf registration statement.

This prospectus supplement relates to the offering of the ADSs. Before buying any of the ADSs that we are offering, we urge you to carefully read this prospectus supplement, together with the accompanying prospectus and the information incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering when making your investment decision. You should also read and consider the information in the documents we have referred you to under the headings “Where You Can Find Additional Information” and “Incorporation by Reference.” These documents contain important information that you should consider when making your investment decision.

This document is in two parts. The first part, this prospectus supplement, describes the specific terms of the ADSs that we are offering and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference herein or therein. The second part, the accompanying prospectus, provides more general information. To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or any document incorporated by reference into this prospectus supplement or the accompanying prospectus that was filed with the SEC before the date of this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement. 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 into this prospectus supplement — the statement in the document having the later date modifies or supersedes the earlier statement.

You should rely only on the information contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering. We have not, and JonesTrading as sales agent has not, authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and JonesTrading is not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted.

You should assume that the information appearing in this prospectus supplement, the documents incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering, is accurate only as of the date of those respective documents. Our business, financial condition, results of operations and prospects may have changed since those dates. You should read this prospectus supplement, the documents incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering, in their entirety before making an investment decision. We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference herein or in the accompanying prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreement, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were accurate only as of the date when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

Sales of the ADSs will only be conducted through Nasdaq or any other existing U.S. trading market for the ADSs. No sales of the ADSs will be conducted through Euronext. The distribution of this prospectus supplement and the accompanying prospectus and the offering of the ADSs in certain jurisdictions may be restricted by law. Neither we nor JonesTrading are offering to sell or seeking offers to purchase the ADSs in any jurisdiction where the offer or sale is not permitted. We have not done anything that would permit this

The offering prices per ADS in this offering may exceed the net tangible book value per ADS outstanding prior to this offering. Assuming that an aggregate of 5,490,114 ADSs are sold at a price of $2.63 per share, which was the last reported sale price of our ordinary shares on Nasdaq on September 30, 2022, for aggregate gross proceeds of $14,439,000, and after deducting commissions and estimated offering expenses payable by us, you would experience immediate dilution of $1.48 per ADS, representing the difference between our as adjusted net tangible book value per share as of June 30, 2022, after giving effect to this offering, and the assumed offering price. The exercise of outstanding warrants would result in further dilution of your investment. See the section entitled “Dilution” herein for a more detailed illustration of the dilution you may incur if you participate in this offering. Subject to certain limitations in the Sales Agreement and compliance with applicable law, the number of ADSs that are sold through JonesTrading after our instruction will fluctuate based on a number of factors, including the market price of our ADSs during the sales period, the limits we set with JonesTrading in any instruction to sell ADSs, and the demand for our ADSs during the sales period. Purchasers of the ADSs we sell, as well as our existing shareholders, will experience significant dilution if we sell ADSs at prices significantly below the price at which they invested.

The trading price of our ADSs has been, and is likely to continue to be, highly volatile. The market price of an investment in our ADSs may fall sharply at any time due to this volatility. The market price for our ADSs has varied between a high price of $25.04 on November 4, 2021 and a low price of $1.51 on May 12, 2022, in the 12-month period ended on the date of this prospectus supplement. The market prices of our ADSs are likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including the other factors discussed in our filings with the SEC and the section entitled “Risk Factors” in “Item 3.D. — Risk Factors” of our Annual Report or our subsequent reports filed with the SEC; variations in our quarterly operating results from our expectations or those of securities analysts or investors; downward revisions in securities analysts’ estimates; and announcement by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments.

Market conditions may result in volatility in the level of, and fluctuations in, market prices of stocks generally and, in turn, our ADSs and sales of substantial amounts of our ADSs in the market, in each case being unrelated or disproportionate to changes in our operating performance. Concerns over global stability and economic conditions in the United States and abroad have contributed to the extreme volatility of the markets, which may have an effect on the market price of ADSs.

Our management will have broad discretion in the application of the net proceeds, if any, that we receive from this offering, including applications for working capital, possible acquisitions and other general corporate purposes, and we may spend or invest these proceeds in a way with which our shareholders disagree or in ways that may impair the value of your investment in our ADSs. The failure by our management to apply these funds effectively could harm our business and financial condition. Pending their use, we may invest the net proceeds, if any, from this offering in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

Sales of a substantial number of our ADSs pursuant to this offering in the public market or the perception that such sales might occur could depress the market price of our ADSs and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our ADSs. The sale or the availability for sale of a large number of our ADSs in the public market could cause the market price of our ADSs to decline.

Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our ADSs to decline and existing shareholders may not agree with our financing plans or the terms of such financings.

By participating in this offering you will become a holder of our ADSs with underlying ordinary shares in a company incorporated under Danish law. Holders of our ADSs are not treated as holders of our ordinary shares, unless they withdraw the ordinary shares underlying their ADSs in accordance with the deposit agreement and applicable laws and regulations. The depositary is the holder of the ordinary shares

Except as described in this prospectus supplement, the accompanying prospectus and the deposit agreement covering our ADSs, holders of our ADSs will not be able to exercise voting rights attaching to the ordinary shares represented by the ADSs. Under the terms of the deposit agreement, holders of our ADSs may instruct the depositary to vote the ordinary shares underlying their ADSs. Otherwise, holders of ADSs will not be able to exercise their right to vote unless they withdraw the ordinary shares underlying their ADSs to vote them in person or by proxy in accordance with applicable laws and regulations and our Articles of Association. Even so, our ADS holders may not know about a meeting far enough in advance to withdraw those ordinary shares. If we ask for the instructions of holders of the ADSs, the depositary, upon timely notice from us, will notify our ADS holders of the upcoming vote and arrange to deliver our voting materials to them. Upon our request, the depositary will mail to holders a shareholder meeting notice that contains, among other things, a statement as to the manner in which voting instructions may be given. We cannot guarantee that our ADS holders will receive the voting materials in time to ensure that they can instruct the depositary to vote the ordinary shares underlying their ADSs. A shareholder is only entitled to participate in, and vote at, the meeting of shareholders, provided that it holds our ordinary shares as of the record date set for such meeting and otherwise complies with our Articles of Association. In addition, the depositary’s liability to our ADS holders for failing to execute voting instructions or for the manner of executing voting instructions is limited by the deposit agreement. As a result, holders of our ADSs may not be able to exercise their right to give voting instructions or to vote in person or by proxy and they may not have any recourse against the depositary or us if the ordinary shares underlying their ADSs are not voted as they have requested or if such shares cannot be voted.

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

We are entitled to amend the deposit agreement and to change the rights of our ADS holders under the terms of such agreement, without the prior consent of our ADS holders. We and the depositary may agree to amend the deposit agreement in any way we decide is necessary or advantageous to us or to the depositary. Amendments may reflect, among other things, operational changes in the ADS program, legal developments affecting our ADSs or changes in the terms of our business relationship with the depositary. In the event that the terms of an amendment are materially disadvantageous to our ADS holders, such ADS holders will only receive 30 days’ advance notice of the amendment, and no prior consent of our ADS holders is required under the deposit agreement. Furthermore, we may decide to direct the depositary to terminate

For corporate investors, dividends paid (subject to the same uncertainty as described immediately above) on Subsidiary Shares and Group Shares generally are tax-exempt irrespective of ownership period.

Dividends paid on Taxable Portfolio Shares are taxable at the general corporate rate of 22% and tax is generally withheld with 22%.

It is currently not clear under current Danish tax legislation or case law how the listed ADSs are to be treated for tax purposes, and therefore no level of assurance can be given on this matter. For the purpose of the below comments, it is assumed that non-Danish tax resident holders of the ADSs should be treated as holders of listed shares in our company for both Danish corporate law purposes and Danish tax purposes, even though our ordinary shares are not admitted to trading on a regulated market. Recent communications and binding rulings from the Danish Tax Assessment Council indicates that the holders of ADSs for Danish tax purposes are treated as holders of listed ordinary shares. The same communications and rulings indicate that the actual distribution of dividends on ADSs to Danish investors are considered dividends for Danish tax purposes. However, it should be emphasized that these communications and binding rulings are based on an individual analysis based on the actual facts and circumstances and terms and conditions of the depositary agreement implying that a holder of ADSs might not be able to rely on said rulings.

In the event that the holders of ADSs s not treated as holding listed shares in our company, it is likely that they will be treated as either holding unlisted shares or financial instruments for Danish tax purposes.

As described above, the below summary assumes that the holders of ADSs listed in the U.S. should be treated as holding listed ordinary shares in our company for Danish tax purposes, but if this is not the case, then this will impact the Danish tax treatment of the holders of ADSs, including in respect of the taxation of dividends paid to holders of ADSs.

Holders of the ADSs not resident in Denmark are normally not subject to Danish taxation on any gains realized on the sale of ADSs, irrespective of the ownership period, subject to certain anti-avoidance rules seeking to prevent that taxable dividend payments are converted to tax exempt capital gains.

Non-residents of Denmark are not subject to additional Danish income tax in respect to dividends received on shares.

If the holders of the ADSs are considered beneficial owners of the dividends according to the applicable double tax treaty between Denmark and the tax residence country of the ADS holder, the withholding tax rate under such double tax treaty may apply to the extent the tax residency of the ADS holder can be documented and to the extent it can be documented that the dividends are in fact paid onwards to the holder of the ADSs as the beneficial owner.

For holders of ADSs (as the beneficial owners of the dividends on the ordinary shares), if the withholding tax rate applied is higher than the applicable final tax rate (as reduced according to domestic law or an applicable double tax treaty) for the holder of ADSs, a request for a refund of Danish tax in excess hereof can be made in the following situations:

In the event that the ADS holder is a resident of a state with which Denmark has entered into a tax treaty, the holder may generally, through certain certification procedures, seek a refund from the Danish tax authorities of the tax withheld in excess of the applicable treaty rate, which is typically 15%. Denmark has entered into tax treaties with approximately 80 countries, including the United States, Switzerland and almost all members of the European Union. The tax treaty between Denmark and the United States generally provides for a 15% tax rate.

If the ADS holder holds less than 10% of the nominal share capital (in the form of ordinary shares in the company and not on the basis of the number of the ADSs issued) of the company and the ADS holder is tax resident in a state which has a double tax treaty or an international agreement, convention or other administrative agreement on assistance in tax matters according to which the competent authority in the state of the ADS holder is obligated to exchange information with Denmark, dividends are subject to tax at a rate of 15%. If the ADS holder is tax resident outside the European Union, it is an additional requirement for eligibility for the 15% tax rate that the ADS holder together with related ADS holders holds less than 10% of the nominal share capital of the company.

Note that the reduced tax rate does not affect the withholding rate, which is why the holder must claim a refund as described above in order to benefit from the reduced rate.

Where a non-resident of Denmark holds shares which can be attributed to a permanent establishment in Denmark, dividends are taxable pursuant to the rules applying to Danish tax residents described above.

The recent communications and binding rulings from the Danish Tax Assessment Council indicates that a holder of ADSs selling such ADSs back to the company should be exempt from withholding tax on the basis of a specific exception applying to shares in listed companies. It should be emphasized that these rulings are based on an individual analysis based on the actual facts and circumstances and terms and conditions of the depositary agreement implying that a holder of ADSs might not be able to rely on said rulings.

As described above, the recent communications and binding rulings from the Danish Tax Assessment Council indicates that holders of ADSs for Danish tax purposes are treated as holders of listed ordinary shares. The same communications and rulings indicate that the actual distribution of dividends on ADSs to investors are considered dividends for Danish tax purposes. In principle the holders of the ADSs should

If the holders of ADS for Danish purposes are treated as holders of the ordinary shares in the company and are entitled to apply for a refund of Danish withholding tax on dividends paid by the company, then the below should apply.

Dividends paid to companies are generally subject to 27% withholding tax. The withholding tax is 44% for dividends paid on Group Shares and Subsidiary Shares held by beneficial owners in Blacklisted Jurisdictions as mentioned above.

Non-residents of Denmark are not subject to additional Danish income tax in respect to dividends received on shares.

If the investors of the ADSs are considered beneficial owners of the dividends according to the applicable double tax treaty between Denmark and the tax residence country of the ADS holder, the withholding tax rate under such double tax treaty may apply to the extent the tax residency of the ADS holder can be documented and to the extent it can be documented that the dividends are in fact paid onwards to the holder of the ADSs as the beneficial owner.

For investors (as beneficial owners of the dividends on the ordinary shares), if the withholding tax rate applied is higher than the applicable final tax rate (as reduced according to domestic law or an applicable double tax treaty) for the investor, a request for a refund of Danish tax in excess hereof can be made.

Dividends from Subsidiary Shares are tax exempt provided the taxation of the dividends is to be waived or reduced in accordance with the Parent-Subsidiary Directive (2011/96/EEC) or in accordance with a tax treaty with the jurisdiction in which the company investor is resident. If Denmark is to reduce taxation of dividends to a foreign company under a tax treaty, Denmark will not — as a matter of domestic law — exercise such right and will in general exempt from imposing any withholding tax. Further, dividends from Group Shares — not also being Subsidiary Shares — are exempt from Danish tax provided the company investor is a resident of the European Union or the EEA and provided the taxation of dividends should have been waived or reduced in accordance with the Parent-Subsidiary Directive (2011/96/EEC) or in accordance with a tax treaty with the country in which the company investor is resident had the shares been Subsidiary Shares.

Dividend payments on both Tax-Exempt and Taxable Portfolio Shares will generally be subject to withholding tax at a rate of 27% irrespective of ownership period. While the actual withholding tax rate is as a starting point 27%, it can be reduced if certain requirements are met as described below. If the withholding tax rate applied is higher than the applicable final tax rate for the shareholder, a request for a refund of Danish tax in excess hereof can be made by the shareholder in the following situations:

In the event that the shareholder is a resident of a state with which Denmark has entered into a double taxation treaty, the shareholder may generally, through certain certification procedures, seek a refund from the Danish tax authorities of the tax withheld in excess of the applicable treaty rate, which is typically 15%. Denmark has entered into tax treaties with a large number countries, including the United States and almost all members of the European Union. The tax treaty between Denmark and the United States generally provides for a 15% rate.

If the shareholder holds less than 10% of the nominal share capital (in the form of ordinary shares in the company and not on the basis of the number of the ADSs issued) in the company and the shareholder is resident in a jurisdiction which has a tax treaty or an international agreement, convention or other administrative agreement on assistance in tax according to which the competent authority in the state of the shareholder is obligated to exchange information with Denmark, dividends are generally subject to a tax

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of the ADSs that, for United States federal income tax purposes, is:

If a partnership or other pass-through entity (including any entity or arrangement treated as a partnership or other pass-through entity for U.S. federal income tax purposes) holds the ADSs, the tax treatment of a person treated as a partner or other owner in the partnership or other pass-through entity for U.S. federal income tax purposes generally will depend on the status of the partner or other owner and the activities of the partnership or other pass-through entity. Partnerships (and other entities or arrangements so treated for U.S. federal income tax purposes) and their future partners should consult their own tax advisors.

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

Under the United States federal income tax laws, and subject to the PFIC rules discussed below under “— Passive Foreign Investment Company Considerations”, any distributions of cash or other property with respect to the ADSs (including any amounts withheld in respect thereof), generally will, to the extent made out of our current and accumulated earnings and profits as determined for U.S. federal income tax purposes, constitute dividends for U.S. federal income tax purposes. Generally, the gross amount of any dividend we pay out of our current or accumulated earnings and profits (as determined for United States federal income tax purposes) is includible in income for a U.S. Holder and subject to U.S. federal income taxation. Dividends paid to a non-corporate U.S. Holder that constitute dividend income from a “qualified foreign corporation” will be taxable at a preferential tax rate applicable to long-term capital gains, provided that the U.S. Holder holds the ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meets other holding period requirements. A non-United States corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation (i) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for purposes of this provision and which includes an exchange of

We have not made a determination as to whether the Company will or will not be treated as a PFIC in the current taxable year and subsequent taxable years. The determination of PFIC status is inherently factual, is subject to a number of uncertainties, and can be determined only annually after the close of the tax year in question. Additionally, the analysis depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. There can be no assurance that the Company will or will not be determined to be a PFIC for the current tax year or any prior or future tax year, and no opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or will be requested. U.S. Holders should consult their own U.S. tax advisors regarding our PFIC status.

If we were classified as a “passive foreign investment company”, or a “PFIC”, for U.S. federal income tax purposes in any taxable year, a U.S. Holder would be subject to special rules with respect to distributions on and sales, exchanges and other dispositions of the ADSs. A non-U.S. corporation, such as the Company, will be classified as a PFIC for United States federal income tax purposes for any taxable year, if either (i) 75% or more of its gross income for such year consists of certain types of “passive” income (the “income test”) or (ii) 50% or more of the value of its assets (generally determined on the basis of a quarterly average) during such year is attributable to assets that produce or are held for the production of passive income (the “asset test”). For this purpose, cash and assets readily convertible into cash are categorized as passive assets and the company’s goodwill and other unbooked intangibles are taken into account. Passive income generally includes, among other things, dividends, interest, rents, royalties, and gains from the disposition of passive assets. However, certain rents and royalties received from unrelated parties in connection with the active conduct of a trade or business are not considered passive income for purposes of the PFIC test. For purposes of the PFIC test, 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.

If we were a PFIC with respect to a U.S. Holder, then unless such U.S. Holder makes one of the elections described below, a special tax regime would apply to the U.S. Holder with respect to (i) any “excess distribution” ​(generally, aggregate distributions in any year that are greater than 125% of the average annual distribution received by the holder in the shorter of the three preceding years or the holder’s holding period for the ADSs) and (ii) any gain realized on the sale or other disposition of the ADSs. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over the U.S. Holder’s holding period, (b) the amount deemed realized in each year had been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any taxable period before we became a PFIC, which would be subject to tax at the U.S. Holder’s regular ordinary income rate for the current year and would not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. If we were determined to be a PFIC, this tax treatment for U.S. Holders would apply also to indirect distributions and gains deemed realized by U.S. Holders in respect of stock of any of our subsidiaries determined to be PFICs. In addition, dividend distributions would not qualify for the lower rates of taxation applicable to long-term capital gains discussed above under “— Taxation of Dividends.”

A U.S. Holder that holds the ADSs at any time during a taxable year in which we are classified as a PFIC generally will continue to treat such ADSs as ADSs in a PFIC, even if we no longer satisfy the PFIC income and asset tests described above, unless the U.S. Holder elects to recognize gain, which will be taxed under the excess distribution rules as if such ADSs had been sold on the last day of the last taxable year for which we were a PFIC.

Certain elections by a U.S. Holder would alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment of the ADSs, as described below. These elections include a “qualified electing fund” or “QEF” election and a “mark-to-market” election, which is described in more

We are incorporated in Denmark, and many of our outstanding securities are owned by non-U.S. residents. Under the rules of the SEC, we are currently eligible for treatment as a “foreign private issuer.” As a foreign private issuer, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as United States domestic registrants whose securities are registered under the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act.

This prospectus contains our audited consolidated financial statements as of December 31, 2021 and 2020 and for the years ended December 31, 2021, 2020 and 2019 and the related notes, prepared in accordance with International Financial Reporting Standards or IFRS, as issued by the International Accounting Standards Board, or IASB and our unaudited condensed consolidated interim financial statements as of March 31, 2022, and for the three months ended March 31, 2022 and 2021 and the related notes. The unaudited condensed consolidated interim financial statements of the Company are prepared in accordance with International Accounting Standard 34, “Interim Financial Reporting.” Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with IFRS have been condensed or omitted. Accordingly, these unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited annual consolidated financial statements as of and for the year ended December 31, 2021.

Our financial information is presented in our presentation currency, U.S. Dollar, or USD. Our functional currency is the Danish Krone, or DKK. Certain Danish Krone amounts in this prospectus have been translated solely for convenience into USD at an assumed exchange rate of DKK 6.5612 per $1.00, which was the rounded official exchange rate of such currencies as of December 31, 2021 for the years ended December 31, 2021, 2020 and 2019. We used an assumed exchange rate of DKK 6.7002 per $1.00, which was the official rounded exchange rate of such currencies as of March 31, 2022 for the unaudited interim periods ended March 31, 2022 and 2021. Foreign currency transactions are translated into our functional currency, DKK, using the exchange rates prevailing at the dates of the transactions. Foreign

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described under the heading “Risk Factors” contained in the applicable prospectus supplement and any related free writing prospectus, and in our most recently filed Annual Report on Form 20-F, or our Annual Report, and reports on Form 6-K as updated by our subsequent filings, which are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. Each of the risk factors could adversely affect our business, results of operations, financial condition and cash flows, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations.

This prospectus and the documents incorporated by reference herein contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, that reflect our current expectations and views of future events. Discussions containing these forward-looking statements may be found, among other places, in the sections titled “Information on the Company,” “Risk Factors” and “Operating and Financial Review and Prospects” incorporated by reference from our most recent Annual Report, as well as any amendments thereto, filed with the SEC. Forward-looking statements are based on the current beliefs and assumptions of our management and on information currently available to such management. While our management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments will be as anticipated. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or implied in the forward-looking statements due to of various factors, including, but not limited to, those identified under the section “Item 3. Key Information — D. Risk Factors” in our most recent Annual Report. Known and unknown risks, uncertainties and other factors, including those listed under “Risk Factors” in this prospectus, the applicable prospectus supplement and in any related free writing prospectuses and under similar headings in documents that are incorporated by reference into this prospectus, including our most recent Annual Report and reports on Form 6-K as updated by our subsequent filings, may cause our actual results, performance or achievements to be materially different from those expressed or implied by the forward-looking statements.

You can identify some of these forward-looking statements by words or phrases, such as “may,” “will,” “expect,” “anticipate,” “aim,” “estimate,” “intend,” “plan,” “believe,” “is/are likely to,” “potential,” “continue” or other similar expressions. We have based these forward-looking statements largely on our current expectations and projections about future events that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements include statements relating to:

Under Article 18, Paragraph 2 of the Statute of the European Investment Bank, or the EIB Statute, establishing EIB, a direct equity investment by EIB requires a separate authorization from the EIB Board of Governors pursuant to which the EIB Board of Directors, acting by qualified majority, has to establish the terms and conditions of such direct equity investment. As of the date of this annual report, the EIB Board of Governors has not granted any such special authorization to the EIB Board of Directors. Under the EIB Statute, in the absence of a separate authorization from the EIB Board of Governors, commercial shareholdings financed from EIB’s own resources are not allowed. Since the EIB Loan is being made from EIB’s own resources, the EIB Statute does not allow EIB to acquire any of our ordinary shares, therefore, we fully expect that if and when EIB exercises the EIB Warrants it will do so on either a net cash settlement basis or by means of exercising its Put Right. In either case, we may not have sufficient funds on hand to pay such amounts in which case we may be required to use a portion of the proceeds from our initial public offering in order to meet our obligations to pay the amounts due and payable to EIB upon the exercise of the EIB Warrants.

Under the terms of the EIB Warrant Agreement, EIB may not exercise the EIB Warrants and cause us to settle the exercise of the EIB Warrants on a net cash basis or pursuant to its Put Right, for a period of 180 days from the date of the completion of our initial public offering, provided that such lock-up arrangement shall cease to be effective in the event there is a material adverse event relating to our company as determined in accordance with ordinary principles of Danish law.

The number of our ordinary shares that may be subject to either net cash settlement or EIB’s Put Right upon the exercise of the EIB Warrants are subject to adjustment in the event of changes to our capital structure which are not carried out at the then current market price, provided that there shall be no such adjustment as a result of the issuance of additional shares or warrants to employees as well as for any future exercise of such warrants. In addition, the EIB Warrants are not subject to any adjustment in the event of any capital increases in directed issuances or our ordinary shares following the completion of our initial public offering with customary discounts of up to 10% of the market price.

The board of directors shall appoint and employ an executive management consisting of one to seven members to attend to our day-to-day management, and the board of directors shall determine the terms and conditions of their employment.

Each shareholder is entitled to one vote for each share owned at the time of any general meeting. As compared with Danish citizens, there are no limitations under the articles of association or under Danish law on the rights of foreigners or non-Danish citizens to hold or vote our ordinary shares.

Our shareholders may at general meetings authorize the distribution of ordinary and extraordinary dividends. Our shareholders may not distribute dividends in excess of the recommendation from our board of directors and may only pay out dividends from our distributable reserves, which are defined as results from operations carried forward and reserves that are not bound by law after deduction of loss carried forward.

Our shareholders are eligible to receive any dividends declared and paid out. However, we have not to date declared or paid any dividends and we currently intend to retain all available financial resources and any earnings generated by our operations for use in the business and we do not anticipate paying any dividends in the foreseeable future. The payment of any dividends in the future will depend on a number of factors, including our future earnings, capital requirements, financial condition and future prospects, applicable restrictions on the payment of dividends under Danish law and other factors that our board of directors may consider relevant.

See “Taxation” for a summary of certain tax consequences in respect of dividends or distributions to holders of our ordinary shares or ADSs.

Under Danish law, all shareholders have pre-emptive subscription rights in connection with capital increases that are carried out as cash contributions. An increase in share capital can be resolved by the shareholders at a general meeting or by the board of directors pursuant to an authorization given by the shareholders. In connection with an increase of a company’s share capital, the shareholders may, by resolution at a general meeting, approve deviations from the general Danish pre-emptive rights of the shareholders. Under the Danish Companies Act, such resolution must be adopted by the affirmative vote of shareholders holding at least a two-thirds majority of the votes cast and the share capital represented at the general meeting, and requires that such capital increases will be carried out as a cash contribution at market price.

The board of directors may resolve to increase our share capital without pre-emptive subscription rights for existing shareholders pursuant to the authorizations set forth above under the caption “Authorizations to the Board of Directors”.

Unless future issuances of new shares and/or pre-emptive rights are registered under the Securities Act or with any authority outside Denmark, United States shareholders and shareholders in jurisdictions outside Denmark may be unable to exercise their pre-emptive subscription rights.

Upon a liquidation or winding-up of the Company, shareholders will be entitled to participate, in proportion to their respective shareholdings, in any surplus assets remaining after payment of our creditors.

Pursuant to Section 55 of the Danish Companies Act, a shareholder is required to notify us when such shareholder’s stake represents 5% or more of the voting rights in our company or the nominal value accounts for 5% or more of the share capital, and when a change of a holding already notified entails that the limits of 5, 10, 15, 20, 25, 50, 90 or 100% and the limits of one-third and two-thirds of the share capital’s voting rights or nominal value are reached or are no longer reached. The notification shall be given within two weeks following the date when the limits are reached or are no longer reached. The legal status of the notification obligations is not fully clarified in relation to ADS holders and an ADS holder may be subject to such obligations.

Extraordinary general meetings must be held upon resolution of a general meeting to hold such a meeting or upon request of, the board of directors, our auditors or shareholders representing at least 1/20 of the registered share capital or such lower percentage as our articles of association may provide. Our articles of association do not state such lower percentage.

Holders of ADSs are not entitled to directly receive notices or other materials and may not attend or vote at general meetings.

Resolutions made by the general meeting generally may be adopted by a simple majority of the votes cast, subject only to the mandatory provisions of the Danish Companies Act and our articles of association. Resolutions concerning all amendments to the articles of association must be passed by two-thirds of the votes cast as well as two-thirds of the share capital represented at the general meeting. Certain resolutions, which limit a shareholder’s ownership or voting rights, are subject to approval by a nine-tenth majority of the votes cast and the share capital represented at the general meeting. Decisions to impose or increase any obligations of the shareholders towards the company require unanimity.

There are no quorum requirements generally applicable to general meetings of shareholders. To this extent, our practice varies from the requirement of Nasdaq Listing Rule 5620(c), which requires an issuer to provide in its bylaws for a generally applicable quorum, and that such quorum may not be less than one-third of the outstanding voting shares.

According to Section 73 of the Danish Companies Act, a minority shareholder may require a majority shareholder that holds more than 90% of the company’s registered share capital and the corresponding voting rights to redeem his or her shares. Similarly, a majority shareholder holding more than 90% of the company’s share capital and the corresponding voting rights may, according to Section 70 of the same act, redeem the minority shareholder’s shares. In the event that the parties cannot agree to the terms of redemption and the valuation basis of the redemption price, this shall be determined by an independent evaluator appointed by the court for the district in which the registered office of the company is situated (i.e. currently the Lyngby City Court).

At the general meeting, shareholders are entitled at all times to dismiss a director elected by the general meeting by a simple majority vote.

Pursuant to the Danish Companies Act, in a limited liability company that has employed an average of at least 35 employees in the preceding three years, the employees are entitled to elect a minimum of two representatives and alternate members to the company’s board of directors and up to one half the number of the shareholder elected directors. If the number of representatives to be elected by the employees is not a whole number, such number must be rounded up

Stockholders as of the record date for the meeting are entitled to vote at the meeting, and the board of directors may fix a record date that is no more than 60 nor less than ten days before the date of the meeting,

The board of directors may resolve to increase our share capital without pre-emptive subscription rights for existing shareholders pursuant to the authorizations described above under the caption “Development of Share Capital.”

Unless future issuances of new shares are registered under the Securities Act or with any authority outside Denmark, United States shareholders and shareholders in jurisdictions outside Denmark may be unable to exercise their pre-emptive subscription rights under United States securities law.

Furthermore, it is possible under Danish law to distribute assets other than cash as dividends. If assets other than cash are distributed as dividends, a valuation report must be prepared. The valuation report must be prepared by one or more impartial valuation experts.

Under the Delaware General Corporation Law, no vote of the stockholders of a surviving corporation to a merger is needed, however, unless required by the certificate of incorporation, if (1) the agreement of merger does not amend in any respect the certificate of incorporation of the surviving corporation, (2) the shares of stock of the surviving corporation are not changed in the merger and (3) the number of shares of common stock of the surviving corporation into which any other shares, securities or obligations to be issued in the merger may be converted does not exceed 20% of the surviving corporation’s common stock outstanding immediately prior to the effective date of the merger. In addition, stockholders may not be entitled to vote in certain mergers with other corporations that own 90% or more of the outstanding shares of each class of stock of such corporation, but the stockholders will be entitled to appraisal rights.

The depositary may distribute additional ADSs representing any shares we distribute as a dividend or free distribution. The depositary will only distribute whole ADSs. It will sell shares which would require it to deliver a fraction of an ADS (or ADSs representing those shares) and distribute the net proceeds in the same way as it does with cash. If the depositary does not distribute additional ADSs, the outstanding ADSs will also represent the new shares. The depositary may sell a portion of the distributed shares (or ADSs representing those shares) sufficient to pay its fees and expenses in connection with that distribution.

The depositary will send to ADS holders anything else we distribute on deposited securities by any means it thinks is legal, fair and practical. If it cannot make the distribution in that way, the depositary has a choice. It may decide to sell what we distributed and distribute the net proceeds, in the same way as it does with cash. Or, it may decide to hold what we distributed, in which case ADSs will also represent the newly distributed property. However, the depositary is not required to distribute any securities (other than ADSs) to ADS holders unless it receives satisfactory evidence from us that it is legal to make that distribution. The depositary may sell a portion of the distributed securities or property sufficient to pay its fees and expenses in connection with that distribution. United States securities laws may restrict the ability of the depositary to distribute securities to all or certain ADS holders, and the securities distributed may be subject to restrictions on transfer.

The depositary will deliver ADSs if you or your broker deposits shares or evidence of rights to receive shares with the custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of ADSs in the names you request and will deliver the ADSs to or upon the order of the person or persons that made the deposit.

You may surrender the ADSs to the depositary for the purpose of withdrawal. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer will deliver the shares and any other deposited securities underlying the ADSs to the ADS holder or a person the ADS holder

From time to time, the depositary may make payments to us to reimburse us for costs and expenses generally arising out of establishment and maintenance of the ADS program, waive fees and expenses for services provided to us by the depositary or share revenue from the fees collected from ADS holders. In performing its duties under the deposit agreement, the depositary may use brokers, dealers, foreign currency dealers or other service providers that are owned by or affiliated with the depositary and that may earn or share fees, spreads or commissions.

If the deposit agreement will terminate, the depositary will notify ADS holders at least 90 days before the termination date. At any time after the termination date, the depositary may sell the deposited securities. After that, the depositary will hold the money it received on the sale, as well as any other cash it is holding under the deposit agreement, unsegregated and without liability for interest, for the pro rata benefit of the ADS holders that have not surrendered their ADSs. Normally, the depositary will sell as soon as practicable after the termination date.

After the termination date and before the depositary sells, ADS holders can still surrender their ADSs and receive delivery of deposited securities, except that the depositary may refuse to accept a surrender for the purpose of withdrawing deposited securities or reverse previously accepted surrenders of that kind that have not settled if it would interfere with the selling process. The depositary may refuse to accept a surrender for the purpose of withdrawing sale proceeds until all the deposited securities have been sold. The depositary will continue to collect distributions on deposited securities, but, after the termination date, the depositary is not required to register any transfer of ADSs or distribute any dividends or other distributions on deposited securities to the ADSs holder (until they surrender their ADSs) or give any notices or perform any other duties under the deposit agreement except as described in this paragraph.

The deposit agreement expressly limits our obligations and the obligations of the depositary. It also limits our liability and the liability of the depositary. We and the depositary:

In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

Before the depositary will deliver or register a transfer of ADSs, make a distribution on ADSs, or permit withdrawal of shares, the depositary may require:

The depositary may refuse to deliver ADSs or register transfers of ADSs when the transfer books of the depositary or our transfer books are closed or at any time if the depositary or we think it advisable to do so.

ADS holders have the right to cancel their ADSs and withdraw the underlying shares at any time except:

The depositary will make available for your inspection at its office all communications that it receives from us as a holder of deposited securities that we make generally available to holders of deposited securities. The depositary will send you copies of those communications or otherwise make those communications available to you if we ask it to. You have a right to inspect the register of holders of ADSs, but not for the purpose of contacting those holders about a matter unrelated to our business or the ADSs.

The deposit agreement provides that, to the extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising out of or relating to our ordinary shares, the ADSs or the deposit agreement, including any claim under the United States federal securities laws. If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable in the facts and circumstances of that case in accordance with applicable case law.

You will not, by agreeing to the terms of the deposit agreement, be deemed to have waived our or the depositary’s compliance with United States federal securities laws and the rules and regulations promulgated thereunder.
