SUBJECT TO COMPLETION, DATED DECEMBER 5, 2025

PROSPECTUS

$150,000,000

Ordinary Shares

Preferred Shares

Warrants

Units

We may offer, from time to time, in one or more offerings, ordinary shares, preferred shares, warrants or units, which we collectively refer to as the “securities”. The aggregate initial offering price of the securities that we may offer and sell under this prospectus will not exceed $150,000,000. We may offer and sell any combination of the securities described in this prospectus in different series, at times, in amounts, at prices and on terms to be determined at, or prior to, the time of each offering. This prospectus describes the general terms of these securities and the general manner in which these securities will be offered. We will provide the specific terms of these securities in supplements to this prospectus. The prospectus supplements will also describe the specific manner in which these securities will be offered and may also supplement, update or amend information contained in this prospectus. This prospectus may not be used to consummate a sale of securities unless accompanied by the applicable prospectus supplement. We may also authorize one or more free writing prospectuses to be provided to you in connection with these offerings. You should read this prospectus and any applicable prospectus supplement of free writing prospectus before you invest.

The securities covered by this prospectus may be offered through one or more underwriters, dealers and agents or directly to purchasers. The names of any underwriters, dealers or agents, if any, will be included in a supplement to this prospectus. For general information about the distribution of securities offered, please see “Plan of Distribution”.

Our ordinary shares are traded on the Nasdaq Capital Market under the symbol “MYNZ”. On December 1, 2025, the closing price of our ordinary shares as reported by the Nasdaq Capital Market was $1.13 per share.

Pursuant to General Instruction I.B.5. of Form F-3, in no event will we sell the securities covered hereby in a public primary offering with a value exceeding more than one-third of the aggregate market value of our ordinary shares in any 12-month period until the aggregate market value of our outstanding ordinary shares held by non-affiliates remains exceeds US$75,000,000. The aggregate market value of our outstanding ordinary shares held by non-affiliates, or public float, as of December 5, 2025, was approximately $14.8 million, which was calculated based on 8,945,806  ordinary shares held by non-affiliates and the per ordinary share price of $1.65, which was the closing price of our ordinary shares on Nasdaq on October 7, 2025. During the 12 calendar months prior to and including the date of this prospectus, we have offered or sold $4.9 million of securities pursuant to General Instruction I.B.5 of Form F-3.

On December 30, 2022, we filed with the SEC a registration statement on Form F-3 (File No. 333-269091) utilizing a shelf registration process, which registration statement was declared effective on January 6, 2023 (the “2023 F-3”). Under this shelf registration process, we were initially entitled to, from time to time, sell up to $150 million in the aggregate of ordinary shares, preferred shares, warrants and units. As of the date of this prospectus, we have not sold $120,004,900 of securities under the 2023 F-3. The 2023 F-3 expires on January 6, 2026 and therefore, we are filing this registration statement as a new shelf registration statement, with unsold securities and fees paid under the “expiring” registration statement rolled over herein.

We are an “emerging growth company” as defined in section 3(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are therefore eligible for certain exemptions from various reporting requirements applicable to reporting companies under the Exchange Act (see “Exemptions Under the Jumpstart Our Business Startups Act.”)

Unless otherwise specified in an applicable prospectus supplement, our preferred shares, warrants and units will not be listed on any securities or stock exchange or on any automated dealer quotation system.

This investment involves a high degree of risk. You should purchase securities only if you can afford a complete loss. In reviewing this prospectus and the documents incorporated herein by reference you should carefully consider the matters described under the caption “Risk Factors” beginning on page 12.

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

The date of this Prospectus is                 , 2025

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is a part of a registration statement that we have filed with the SEC utilizing a “shelf” registration process. Under this shelf registration process, we may sell any combination of the securities described in this prospectus in one or more offerings up to an aggregate offering price of $150,000,000. Those securities include ordinary shares (including ordinary shares underlying warrants, preferred shares and units), preferred shares (including preferred shares underlying warrants or units), warrants (including warrants underlying units) and units (which may consist of ordinary shares, preferred shares and/or warrants).

Each time we sell securities, we will provide a supplement to this prospectus that contains specific information about the securities being offered and the specific terms of that offering. The supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the prospectus supplement.

We may offer and sell securities to, or through, underwriting syndicates or dealers, through agents or directly to purchasers. The prospectus supplement for each offering of securities will describe in detail the plan of distribution for that offering.

In connection with any offering of securities (unless otherwise specified in a prospectus supplement), the underwriters or agents may over-allot or effect transactions which stabilize or maintain the market price of the securities offered at a higher level than that which might exist in the open market. Such transactions, if commenced, may be interrupted or discontinued at any time. See “Plan of Distribution.”

Please carefully read both this prospectus and any prospectus supplement together with the documents incorporated herein by reference under “Incorporation of Documents by Reference” and the additional information described below under “Where You Can Find Additional Information.”

Prospective investors should be aware that the acquisition of the securities described herein may have tax consequences. You should read the tax discussion contained in the applicable prospectus supplement and consult your tax advisor with respect to your own particular circumstances.

You should rely only on the information contained or incorporated by reference in this prospectus and any prospectus supplement. We have not authorized anyone to provide you with different information. The distribution or possession of this prospectus in or from certain jurisdictions may be restricted by law. This prospectus is not an offer to sell these securities and is not soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted or where the person making the offer or sale is not qualified to do so or to any person to whom it is not permitted to make such offer or sale. The information contained in this prospectus is accurate only as of the date of this prospectus and any information incorporated by reference is accurate as of the date of the applicable document incorporated by reference, regardless of the time of delivery of this prospectus or of any sale of the securities. Our business, financial condition, results of operations and prospects may have changed since those dates.

In this prospectus and in any prospectus supplement, unless the context otherwise requires, references to the term(s) “we”, “us”, “our”, “Company”, and “our company”, refer to Mainz Biomed N.V., a Dutch public company with limited liability (naamloze vennootschap), either alone or together with our consolidated subsidiaries as the context requires.

 

 

Recent Developments

 

In November 2024, we entered into a collaboration agreement with Life Technologies Corporation, a subsidiary of Thermo Fisher Scientific Inc. (“Thermo Fisher”). Thermo Fisher is a world leader in serving science, with annual revenue over $40 billion in its latest fiscal year. The collaboration agreement provides us the opportunity to develop our mRNA based next generation assays on the Thermo Fisher Extraction (King Fisher) and PCR (QuantStudio) platforms. Life Science Technologies will contribute development resources and provide the extraction and PCR instrumentation and consumables during development at significant discounts to market. There is no minimum cost expenditure in connection with the development of the assays. All of the development work will occur in our facility in Mainz, Germany.

 

	Thermo KingFisher APEX	QuantStudio™ 7 Pro Dx (Thermo Fisher Scientific)

 

We have also recently entered into an agreement with Quest Diagnostics to provide clinical trial laboratory services for our ReconAAsense study, a prospective clinical study that will include approximately 15,000 subjects from 150 sites across the United States to develop data supporting FDA validation of the next generation test. In addition, we will provide Quest with the option to exercise semi-exclusive rights to provide testing services based on the test kit for an eighteen-month period, assuming its approval by the FDA.

 

In March 2025, we acquired a license from Liquid Bioscience, Inc. to access a portfolio of novel mRNA biomarkers for the non-invasive detection of pancreatic cancer with a blood test. The agreement grants us an exclusive, world-wide, license to make, use, and develop these biomarkers until our option to acquire the biomarkers expires. In exchange for such license, we are to make fixed payments to Liquid, which fixed amount shall increase upon certain milestones being met.

 

RISK FACTORS

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks and uncertainties described under the section titled “Risk Factors” contained in:

together with other information in this prospectus, the documents incorporated by reference and any free writing prospectus that we may authorize for use in connection with a specific offering. The risks described in these documents are not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occur, our business, financial condition, results of operations or cash flow could be harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section below titled “Cautionary Note Regarding Forward-Looking Statements.”

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Exchange Act. All statements other than statements of historical facts contained in this prospectus, including, without limitation, statements regarding our future results of operations and financial position, business strategy, transformation, strategic priorities and future progress, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “project,” “believe,” “estimate” or “predict” “or the negative of these terms or other similar expressions. The forward-looking statements in this prospectus are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this prospectus and are subject to a number of important factors that could cause actual results to differ materially from those in the forward-looking statements, including the factors described in the sections entitled “Risk Factors” and in our periodic filings with the SEC. Because forward-looking statements are inherently subject to risks and uncertainties, you should not rely on these forward-looking statements as predictions of future events. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

USE OF PROCEEDS

Unless we otherwise indicate in a prospectus supplement, we currently intend to use the net proceeds from the sale of our securities for working capital purposes.

More detailed information regarding the use of proceeds from the sale of securities, including any determinable milestones at the applicable time, will be described in any applicable prospectus supplement. We may also, from time to time, issue securities otherwise than pursuant to a prospectus supplement to this prospectus.

CAPITALIZATION AND INDEBTEDNESS

Our capitalization will be set forth in the applicable prospectus supplement or in a report on Form 6-K subsequently furnished to the SEC and specifically incorporated by reference into this prospectus.

DILUTION

If required, we will set forth in a prospectus supplement the following information regarding any material dilution of the equity interests of investors purchasing securities in an offering under this prospectus:

DIVIDEND POLICY

Under Dutch law, we may only pay dividends following the closing of the offering to the extent our shareholders’ equity (eigen vermogen) exceeds the sum of the paid-up and called-up share capital plus the reserves required to be maintained by Dutch law or by our articles of association. Subject to such restrictions, the amount of any distributions will depend on many factors, such as our results of operations, financial condition, cash requirements, prospects and other factors deemed relevant by our board of directors.

Our articles of association prescribe that profits in any financial year will be distributed first to holders of our preferred shares, if any are outstanding. Any remaining profits may be reserved by our Board of Directors.

We have not adopted a formal dividend policy with respect to future dividends. We may adopt such a policy in the future.

OFFER AND LISTING DETAILS

We may offer and issue from time-to-time ordinary shares, preferred shares, warrants to purchase ordinary shares or preferred shares and units, or any combination thereof, up to an aggregate initial offering price of up to $150,000,000 in one or more transactions under this shelf prospectus. The price of securities offered will depend on a number of factors that may be relevant at the time of offer. See “Plan of Distribution.”

Our ordinary shares began trading on the Nasdaq Capital Market on November 4, 2021 under the symbol “MYNZ”. The following table sets out the high and low bid price for our securities in each completed fiscal quarter since January 1, 2023 as quoted on the Nasdaq Stock Market:

There is no market for any of our preferred shares, warrants or units, and we do not expect to list such securities on any exchange or quotation system or for a public market to develop for any of those securities.

DESCRIPTION OF CAPITAL Stock

The following description of our Articles of Association, as last amended by our Deed of Amendment on November 13, 2025, is intended as a summary only and does not constitute legal advice regarding those matters and should not be regarded as such. The description is qualified in its entirety by reference to the complete text of the Articles of Association.

Overview

We were incorporated on March 8, 2021 as a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) under Dutch law, and on November 9, 2021 we converted into a Dutch public company with limited liability (naamloze vennootschap).

We are registered in the Commercial Register of the Chamber of Commerce (Kamer van Koophandel) in the Netherlands under number 82122571. We have our corporate seat is in Amsterdam, the Netherlands and our registered office is at Robert-Koch Strasse 50, 55129 Mainz, Federal Republic of Germany.

Our ordinary shares are subject to, and have been created under, Dutch law. Set forth below is a summary of relevant information concerning the material provisions of our articles of association and applicable Dutch law.

Board of Directors

We have a one-tier board structure. The board of directors of the Company (the “Board of Directors”) consists of one executive directors and three non-executive directors. The Board of Directors shall consist of such number of executive Directors as the Board of Directors may determine.

The Board of Directors will be charged with the management of the company. In fulfilling their duties, our directors will serve the interest of the company and the business connected with it. The executive directors and the executive committee are charged with the day-to-day management of the company. Supervision of the fulfilment of duties by the executive directors and of the general course of the company’s affairs and the business connected with it will primarily be carried out by the non-executive directors. The executive directors must in due time provide the non-executive directors with the information they need to carry out their duties.

Our directors will be elected by the general meeting upon a binding nomination. The Board of Directors will be authorized to nominate one or more director candidates for appointment at the general meeting. The general meeting may at all times overrule the binding nature of each nomination by a resolution adopted by a majority of at least two thirds of the votes cast, representing more than half of the issued share capital.

The general meeting may at any time suspend and dismiss a non-executive director or executive director. The general meeting may only adopt a resolution to suspend or dismiss a non-executive director or executive director by a majority of at least two thirds of the votes cast, representing more than half of the issued share capital, unless the resolution is adopted on the basis of a proposal of the Board of Directors.

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

Our authorized share capital consists of 11,250,000 ordinary shares with a nominal value of EUR 0.01 per share and 1,250,000 preferred shares with a nominal value of EUR 0.01 per share. The preferred shares are divided into five series, each consisting of 250,000 preferred shares. Currently there are no preferred shares outstanding. Our authorized share capital will be increased into an authorized share capital of €500,000 divided into (i) 45,000,000 ordinary shares and (ii) 5,000,000 preferred shares if the number of outstanding ordinary shares equals or exceeds 10,000,000.

The number of ordinary shares included in the authorized share capital may be decreased and the number of preferred shares included in the authorized share capital may be increased pursuant to a resolution of the Board of Directors by a number not exceeding the number of ordinary shares included in the authorized share capital which have not been issued and which are not subject to any rights to subscribe for ordinary shares.

The preferred shares may, at the request of the holder, be converted into ordinary shares. The conditions for conversion and the further terms and conditions related to the preferred shares will be determined by our Board of Directors, subject to the prior approval of our general meeting and the meeting of holders of the series of preferred shares concerned, if such series of preferred shares has been issued and are held by persons other than us. The preceding sentence applies by analogy to any adjustment to the conditions.

Issuance of shares

Under Dutch law, shares are issued and rights to subscribe for shares are granted pursuant to a resolution of our general meeting. Our articles of association provide that the general meeting may only resolve to issue shares upon the proposal of our Board of Directors. The general meeting may authorize the Board of Directors to issue new ordinary shares or grant rights to subscribe for ordinary shares. The authorization can be granted and extended, in each case for a period not exceeding five years. For as long as, and to the extent, that such authorization is effective, our general meeting will not have the power to issue ordinary shares.

A resolution of the general meeting has irrevocably authorized our Board of Directors until November 9, 2026, to issue ordinary shares and preferred shares up to the amount of the authorized share capital (from time to time).

Pre-emptive Rights

Subject to restrictions in our articles of association, holders of ordinary shares have pre-emptive rights in relation to newly issued ordinary shares under Dutch law.

Under our articles of association, the pre-emptive rights in respect of newly issued ordinary shares may be restricted or excluded by a resolution of our general meeting, which resolution requires a two-thirds majority of the votes cast if less than half of the issued share capital is present or represented at the meeting. The general meeting may authorize our Board of Directors to limit or exclude the pre-emptive rights in respect of newly issued ordinary shares. Such authorization for our Board of Directors can be granted and extended, in each case for a period not exceeding five years.

A resolution of the general meeting has irrevocably authorized our Board of Directors until November 9, 2026 to limit or exclude pre-emptive rights on ordinary shares.

Pre-emptive rights do not exist with respect (a) to the issue of ordinary shares or grant of rights to subscribe for ordinary shares to our employees or a “group” company of ours, (b) the issue of ordinary shares against a contribution other than cash, and (c) preferred shares to be issued. A holder of preferred shares has no pre-emptive right to acquire newly issued ordinary shares.

Transfer of Ordinary Shares

Under Dutch law, transfers of ordinary shares (other than in book-entry form) require a written deed of transfer and, unless the company is a party to the deed of transfer, and acknowledgement by or proper service upon the company to be effective.

Our articles of association provide that, if one or more ordinary shares or preferred shares are admitted to trading on Nasdaq or any other regulated foreign stock exchange located in the United States the laws of the State of New York will apply to the property law aspects of the ordinary shares and preferred shares included in the part of the register of shareholders kept by the relevant transfer agent.

Form of Ordinary Shares

Pursuant to our articles of association, the ordinary shares and preferred shares are in registered form.

Purchase and Repurchase of Ordinary Shares

Under Dutch law, we may not subscribe for newly issued ordinary shares. We may acquire ordinary shares, subject to applicable provisions and restrictions of Dutch law and our articles of association, to the extent that:

Other than ordinary shares acquired for no valuable consideration or under universal title of succession (onder algemene titel) (e.g., through a merger or spin off) under statutory Dutch or other law, we may acquire ordinary shares only if our general meeting has authorized our Board of Directors to do so. An authorization by our general meeting for the acquisition of ordinary shares can be granted for a maximum period of 18 months. Such authorization must specify the number of ordinary shares that may be acquired, the manner in which these shares may be acquired and the price range within which the shares may be acquired. No authorization of our general meeting is required if ordinary shares are acquired by us on Nasdaq with the intention of transferring such ordinary shares to our employees or employees of a group company pursuant to an arrangement applicable to them. For each annual general meeting, we expect that our Board of Directors, will place on the agenda a proposal to re-authorize our Board of Directors to repurchase shares for a period of 18 months from the date of the resolution. We cannot derive any right to any distribution from ordinary shares, or voting rights attached to ordinary shares acquired by it.

A resolution of the general meeting has irrevocably authorized our Board of Directors for a period of 18 months to resolve for us to acquire fully paid-up ordinary shares up to the maximum number of ordinary shares permitted pursuant to the law and our articles of association from time to time, through privately negotiated repurchases, in self-tender offers, or through accelerated repurchase arrangements, at prices ranging from the nominal value of the ordinary shares up to one hundred and ten percent (110%) of the market price of ordinary shares, provided that (i) for open market or privately negotiated repurchases, the market price will be the last closing price for ordinary shares on the Nasdaq Stock Market prior to the transaction, (ii) for self-tender offers, the market price will be the volume weighted average price for the ordinary shares on the Nasdaq Capital Market during a period, determined by the Board of Directors, of no less than one and no more than five consecutive trading days immediately prior to the expiration of the tender offer, and (iii) for accelerated repurchase arrangements, the market price will be the volume weighted average price of the ordinary shares on the Nasdaq Capital Market over the term of the arrangement. The volume weighted average price for any number of trading days will be calculated as the arithmetic average of the daily volume weighted average price on those trading days.

Pursuant to a resolution of the general meeting dated June 2, 2025, our Board of Directors is furthermore irrevocably authorized for a period of 18 months, until November 27, 2026, to resolve for us to acquire fully paid up preferred shares up to the maximum number of preferred shares permitted pursuant to the law and our articles of association from time to time and that preferred shares may be acquired through privately negotiated repurchases, in self-tender offers, or through accelerated repurchase arrangements, at prices ranging from the nominal value of the preferred shares up to the higher of (i) the amount that would be paid by us upon cancellation of such preferred shares in accordance with the relevant provisions of our articles of association and (ii) one hundred and ten percent (110%) of the market price of the ordinary shares into which the preferred shares may be converted in accordance with the applicable provisions of our articles of association, whereby the market price shall be determined in the manner as set out in our articles of association.

Capital Reduction

At a general meeting, our shareholders may resolve on the proposal of our Board of Directors to reduce our issued share capital by (i) cancelling ordinary shares and preferred shares or (ii) reducing the nominal value of the ordinary shares and preferred shares by amending our articles of association. In either case, this reduction would be subject to applicable statutory provisions. A resolution to cancel shares may only relate to (i) shares held by us or in respect of which we hold the depository receipts, or (ii) all preferred shares of a particular series. In order to be approved by our general meeting, a resolution to reduce the capital requires approval of a majority of the votes cast at a general meeting if at least half of the issued share capital is represented at such meeting or at least two thirds of the votes cast, if less than half of the issued share capital is represented at such meeting.

Reduction of the nominal value of shares without repayment shall be effected proportionally to all ordinary shares and preferred shares. The requirement of proportionality may be waived by agreement of all shareholders concerned.

A resolution that would result in a reduction of capital requires approval by a majority of the votes cast of each group of shareholders of the same class whose rights are prejudiced by the reduction. In addition, a reduction of capital involves a two-month waiting period during which creditors have the right to object to a reduction of capital under specified circumstances.

General Meeting

General meetings are held in Amsterdam, Rotterdam, The Hague, Arnhem, Utrecht, or in the municipality of Haarlemmermeer (Schiphol Airport), the Netherlands. All of our shareholders and others entitled to attend our general meetings are authorized to address the meeting and, in so far as they have such right, to vote, either in person or by proxy.

We will hold at least one general meeting each year, to be held within six months after the end of its financial year. A general meeting will also be held within three months after our Board of Directors has determined it to be likely that our equity has decreased to an amount equal to or lower than half of its paid up and called up capital, in order to discuss the measures to be taken if so required. If our Board of Directors fails to hold such general meeting in a timely manner, each shareholder and other person entitled to attend our general meeting may be authorized by the Dutch court to convene our general meeting.

Our Board of Directors may convene additional extraordinary general meetings at its discretion, subject to the notice requirements described below. Pursuant to Dutch law, one or more shareholders and/or others entitled to attend general meetings of shareholders, alone or jointly representing at least 10% of our issued share capital, may on their application be authorized by the Dutch court to convene a general meeting. The Dutch court will disallow the application if (i) the applicants have not previously requested in writing that our Board of Directors convenes a shareholders’ meeting or (ii) our Board of Directors convenes a shareholders’ meeting or (ii) our Board of Directors has not taken the necessary steps so that the shareholders’ meeting could be held within six weeks after such request.

The general meeting is convened by a notice, which includes an agenda stating the items to be discussed and the location and time of our general meeting. For the annual general meeting the agenda will include, among other things, the adoption of our annual accounts, the appropriation of its profits or losses and proposals relating to the composition of and filling of any vacancies on Board of Directors. In addition, the agenda for a general meeting includes such additional items as determined by our Board of Directors. Pursuant to Dutch law, one or more shareholders and/or others entitled to attend general meetings of shareholders, alone or jointly representing at least 3% of the issued share capital, have the right to request the inclusion of additional items on the agenda of shareholders’ meetings. Such requests must be made in writing, and may include a proposal for a shareholder resolution, and must be received by us no later than on the 60^th day before the day the relevant shareholders’ meeting is held. Under our articles of association, certain items can only be put on the agenda as a voting item by our Board of Directors. Shareholders meeting the relevant requirements may still request the inclusion of such items on the agenda as a discussion item.

We will give notice of each general meeting by publication on its website and, to the extent required by applicable law, in a Dutch daily newspaper with national distribution, and in any other manner that we may be required to follow in order to comply with Dutch law and applicable stock exchange and SEC requirements. We will observe the statutory minimum convening notice period for a general meeting. Holders of registered shares may further be provided notice of the meeting in writing at their addresses as stated in its shareholders’ register.

Pursuant to our articles of association and Dutch law, our Board of Directors may determine a record date (registratiedatum) of 28 calendar days prior to a general meeting to establish which shareholders and others with meeting rights are entitled to attend and, if applicable, vote at our general meeting. The record date, if any, and the manner in which shareholders can register and exercise their rights will be set out in the notice of our general meeting. Our articles of association provide that a shareholder must notify us in writing of his or her intention to attend (or be represented at) our general meeting, such notice to be received by us on the date set by our Board of Directors in accordance with our articles of association and as set forth in the convening notice.

Our general meeting will be presided over by the chairman of our Board of Directors, who, nevertheless, may charge another person to preside over the meeting in his place even if he or she is present at the meeting. If the chairman of our Board of Directors is absent and he or she has not charged another person to preside over the meeting in his or her place, the directors present at the meeting will appoint one of them to be chairman. In the absence of all directors, our general meeting will appoint its chairman.

Voting Rights and Quorum

In accordance with Dutch law and our articles of association, each ordinary share, irrespective of which class it concerns, confers the right on the holder thereof to cast one vote at our general meeting. The voting rights attached to any ordinary shares held by us or our direct or indirect subsidiaries are suspended, unless the ordinary shares were encumbered with a right of usufruct or a pledge in favor of a party other than us or a direct or indirect subsidiary before such ordinary shares were acquired by us or such a subsidiary, in which case, the other party may be entitled to exercise the voting rights on the ordinary shares. We may not exercise voting rights for ordinary shares in respect of which its or a direct or indirect subsidiary has a right of usufruct or a pledge.

Voting rights may be exercised by shareholders or by a duly appointed proxy holder (the written proxy being acceptable to the chairman of our general meeting) of a shareholder, which proxy holder need not be a shareholder. The holder of a usufruct or pledge on shares will have the voting rights attached thereto if so provided for when the usufruct or pledge was created.

Under our articles of association, blank votes (votes where no choice has been made), abstentions and invalid votes will not be counted as votes cast. However, shares in respect of which a blank vote or invalid vote has been cast and shares in respect of which the person with meeting rights who is present or represented at the meeting has abstained from voting are counted when determining the part of the issued share capital that is present or represented at a general meeting. The chairman of our general meeting will determine the manner of voting and whether voting may take place by acclamation.

Resolutions of the shareholders are adopted at a general meeting by an absolute majority of votes cast, except where Dutch law or our articles of association provide for a special majority in relation to specified resolutions. Our articles of association do not provide for a quorum requirement, subject to any provision of mandatory Dutch law.

Subject to certain restrictions in our articles of association, the determination during our general meeting made by the chairman of that general meeting with regard to the results of a vote will be decisive. Our Board of Directors will keep a record of the resolutions passed at each general meeting.

Amendment of Articles of Association

At a general meeting, at the proposal of our Board of Directors, our general meeting may resolve to amend the articles of association. A resolution by the shareholders to amend the articles of association requires an absolute majority of the votes cast.

Dissolution and liquidation

Our shareholders may at a general meeting, based on a proposal by our Board of Directors, by means of a resolution passed by an absolute majority of the votes cast resolve that the Company will be dissolved. In the event of dissolution of the company, the liquidation will be effected by our executive directors, under the supervision of our non-executive directors, unless our general meeting decides otherwise.

Certain Other Major Transactions

Our articles of association and Dutch law provide that resolutions of our Board of Directors concerning a material change in our identity, character or business are subject to the approval of our general meeting. Such changes include:

Dividends and Other Distributions

We may only make distributions to its shareholders if our equity exceeds the aggregate amount of the issued share capital and the reserves which must be maintained pursuant to Dutch law.

Under our articles of association, any profits or distributable reserves must first be applied to pay a dividend on the preferred shares, if outstanding. Any amount remaining out of distributable profits is added to our reserves as our Board of Directors determines. After reservation by our Board of Directors of any distributable profits, our general meeting will be authorized to declare distributions on the proposal of our Board of Directors. Our Board of Directors is permitted to declare interim dividends without the approval of the shareholders. Interim dividends may be declared as provided in our articles of association and may be distributed to the extent that the shareholders’ equity, based on interim financial statements, exceeds the paid-up and called-up share capital and the reserves that must be maintained under Dutch law or our articles of association. We may reclaim any distributions, whether interim or not interim, made in contravention of certain restrictions of Dutch law from shareholders that knew or should have known that such distribution was not permissible. In addition, on the basis of Dutch case law, if after a distribution we are not able to pay its due and collectable debts, then our shareholders or directors who at the time of the distribution knew or reasonably should have foreseen that result may be liable to its creditors.

The general meeting may determine that distributions will be made in whole or in part in the form of shares or a currency other than the Euro, provided on the proposal of the Board of Directors. We shall announce any proposal for a distribution and the date when and the place where the distribution will be payable to all shareholders by electronic means of communication with due observance of the applicable law and stock exchange rules. Claims for payment of dividends and other distributions not made within five years from the date that such dividends or distributions became payable will lapse, and any such amounts will be considered to have been forfeited to us (verjaring).

Transfer Agent, Warrant Agent and Registrar

We have appointed Transhare Corporation as the transfer agent, warrant agent, and registrar for our ordinary shares. Transhare Corporation’s telephone number and address is (303) 662-1112 and 17755 US Hwy 19 N, Clearwater, FL 33764.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of ordinary shares or preferred shares. We may issue warrants independently or together with other securities, and the warrants may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and the investors or a warrant agent. Any ordinary shares or preferred shares underlying warrants offered pursuant to this prospectus and an accompanying prospectus supplement are included in the ordinary shares and preferred shares, as applicable, offered thereby and are registered by the registration statement of which this prospectus is a part.

The following summary of material provisions of the warrants and warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to a particular series of warrants. The terms of any warrants offered under a prospectus supplement may differ from the terms described below. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the issue. Those terms may include:

Holders of equity warrants will not be entitled to:

Each warrant will entitle its holder to purchase the principal amount of the number of ordinary shares or preferred shares at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

A holder of warrant certificates may exchange them for new warrant certificates of different denominations, present them for registration of transfer and exercise them at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. Until any warrants to purchase ordinary shares or preferred shares are exercised, the holders of the warrants will not have any rights of holders of the underlying ordinary shares or preferred shares, including any rights to receive dividends or payments upon any liquidation, dissolution or winding up on the ordinary shares or preferred shares, if any.

DESCRIPTION OF UNITS

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

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

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

INCOME TAX CONSIDERATIONS

Material income tax consequences relating to the purchase, ownership and disposition of any of the securities offered by this prospectus will be set forth in the applicable prospectus supplement(s) relating to the offering of those securities.

PLAN OF DISTRIBUTION 

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

We will describe the terms of the offering of the securities and the specific plan of distribution in a prospectus supplement or supplements to this prospectus, any related free writing prospectus that we may authorize to be provided to you, an amendment to the registration statement of which this prospectus is a part or other filings we make with the SEC under the Exchange Act that are incorporated by reference. Such description may include, to the extent applicable:

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

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

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

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

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

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

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