SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the financial statements and other documents incorporated by reference in this prospectus contain forward-looking statements, including statements concerning our industry, our operations, our anticipated financial performance and financial condition, and our business plans and growth strategy and product development efforts. These statements constitute 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 Exchange Act. Many of the forward-looking statements contained in this prospectus can be identified by the use of forward-looking words such as “anticipate,” “believe,” “could,” “expect,” “should,” “plan,” “intend,” “estimate” and “potential,” among others. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates. These forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain and subject to a number of risks and uncertainties.

The following represent some, but not necessarily all, of the factors that could cause actual results to differ from historical results or those anticipated or predicted by our forward-looking statements:

2

Our actual results or performance could differ materially from those expressed in, or implied by, any forward-looking statements relating to those matters. Accordingly, no assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do, what impact they will have on our results of operations, cash flows or financial condition. Additionally, some of the risks and uncertainties identified above may be amplified by the COVID-19 pandemic. It is not possible to predict or identify all such risks. There may be additional risks that we consider immaterial or which are unknown. Except as required by law, we are under no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise.

AFFIMED N.V.

We are a clinical-stage immuno-oncology company focused on discovering and developing highly targeted cancer immunotherapies. Our product candidates represent an innovative approach to cancer treatment that seeks to harness the body’s own immune defenses to fight tumor cells. One of the most potent cells of the human defense arsenal are types of white blood cells called innate immune cells (Natural Killer cells, or NK cells, and macrophages). Leveraging our fit-for-purpose ROCK^® (Redirected Optimized Cell Killing) platform, we develop proprietary, next-generation bispecific antibodies, so-called innate cell engagers, which are designed to direct innate immune cells and establish a bridge to cancer cells. Our innate cell engagers have the ability to bring innate immune cells into the proximity of tumor cells and trigger a signal cascade that leads to the destruction of cancer cells. Due to their novel tetravalent architecture with four binding domains, our innate cell engagers bind to their targets with high affinity and have half-lives that allow for regular intravenous administration. Different dosing schemes are being explored to allow for improved exposure in relapsed and refractory cancer patient populations. Based on their mechanism of action as well as the preclinical and clinical data we have generated to date, we believe that our product candidates as monotherapy or in combination, may ultimately improve response rates, clinical outcomes and survival in cancer patients, and could eventually become a cornerstone of modern targeted oncology care. Building on our leadership in the innate cell engager space, we are also developing novel antibody formats with the potential to tailor innate cell-engaging therapy to different indications and settings.

DESCRIPTION OF SHARE CAPITAL AND ARTICLES OF ASSOCIATION

General

We were incorporated pursuant to the laws of the Netherlands as Affimed Therapeutics B.V. in May 2014 to become a holding company for Affimed Therapeutics AG prior to consummation of our initial public offering. Affimed Therapeutics AG was founded in 2000 as a spin-off from Deutsches Krebsforschungszentrum, the German Cancer Research Centre, or the DKFZ, by Professor Melvyn Little in Heidelberg, Germany. Pursuant to the terms of a corporate reorganization that was completed prior to the consummation of our initial public offering, all of the interests in Affimed Therapeutics AG were exchanged for newly issued common shares of Affimed Therapeutics B.V. and, as a result, Affimed Therapeutics AG became a wholly owned subsidiary of Affimed Therapeutics B.V. Prior to consummation of our initial public offering, we converted into a public company with limited liability (naamloze vennootschap) pursuant to a Deed of Amendment and Conversion. Since then, our legal form has not changed and our legal name is Affimed N.V.

We are registered with the Trade Register of the Chamber of Commerce (handelsregister van de Kamer van Koophandel) under number 60673389. Our corporate seat is in Amsterdam, the Netherlands, and our registered office is in Heidelberg, Germany.

Our authorized share capital is €3,119,500, divided into 311,950,000 common shares, each with a nominal value of €0.01. Our issued share capital is €1,197,971.65 as of September 30, 2021.

Under Dutch law, our authorized share capital is the maximum capital that we may issue without amending our Articles of Association. An amendment of our Articles of Association would require a resolution of the general meeting of shareholders upon proposal by the management board with the prior approval of the supervisory board.

Initial settlement of any common shares to be issued pursuant to this prospectus will take place through The Depository Trust Company, or DTC, in accordance with its customary settlement procedures for equity securities. Each person owning common shares held through DTC must rely on the procedures thereof and on institutions that have accounts therewith to exercise any rights of a holder of the common shares.

Stock Exchange Listing

Our common shares are listed on The Nasdaq Global Market, or Nasdaq, under the symbol “AFMD.”

Articles of Association and Dutch Law

Set forth below is a summary of relevant information concerning our share capital and material provisions of our Articles of Association and applicable Dutch law. This summary does not constitute legal advice regarding those matters and should not be regarded as such.

Company’s Shareholders’ Register

Subject to Dutch law and the Articles of Association, we must keep our shareholders’ register accurate and up-to-date. The management board keeps our shareholders’ register and records names and addresses of all holders of shares, showing the date on which the shares were acquired, the date of the acknowledgement by or notification of us as well as the amount paid on each share. The register also includes the names and addresses of those with a right of use and enjoyment (vruchtgebruik) in shares belonging to another or a pledge in respect of such shares. There is no restriction on the ownership of our shares. Any common shares to be issued pursuant to this prospectus will be held through DTC, therefore DTC or its nominee will be recorded in the shareholders’ register as the holder of the common shares.

Corporate Objectives

Pursuant to the Articles of Association, our corporate objectives are:

Limitation on Liability and Indemnification Matters

Under Dutch law, managing directors and supervisory directors and certain other officers may be held liable for damages in the event of improper or negligent performance of their duties. They may be held jointly and severally liable for damages to the Company and to third parties for infringement of the Articles of Association or of certain provisions of the Dutch Civil Code. In certain circumstances, they may also incur additional specific civil and criminal liabilities. Managing directors and supervisory directors and certain other officers are also insured under an insurance policy taken out by us against damages resulting from their conduct when acting in the capacities as such directors or officers, as applicable. In addition, our Articles of Association provide for indemnification of our current and former managing directors and supervisory directors. These provisions give managing directors and supervisory directors the right, to the fullest extent permitted by law, to recover from us amounts, including but not limited to litigation expenses, and any damages they are ordered to pay, in relation to acts or omissions in the performance of their duties. However, there is generally no entitlement to indemnification for acts or omissions that amount to willful (opzettelijk), intentionally reckless (bewust roekeloos) or seriously culpable (ernstig verwijtbaar) conduct.

Shareholders’ Meetings and Consents

General Meeting

General meetings of shareholders may be held in Amsterdam, Rotterdam, The Hague, Arnhem, Utrecht or the municipality of Haarlemmermeer (Schiphol Airport), the Netherlands. The annual general meeting of shareholders must be held within six months of the end of each financial year. Additional extraordinary general meetings of shareholders may also be held, whenever considered appropriate by the management board or the supervisory board. Pursuant to Dutch law, one or more shareholders, who jointly represent at least one-tenth of the issued capital may, on their application, be authorized by a Dutch district court to convene a general meeting of shareholders. The district court shall disallow the application if it does not appear that the applicants have previously requested the management board and the supervisory board to convene a general meeting of shareholders and neither the management nor the supervisory board has taken the necessary steps so that the general meeting of shareholders could be held within six weeks after the request.

General meetings of shareholders can be convened by a notice, which shall include an agenda stating the items to be discussed, including for the annual general meeting of shareholders, among other things, the adoption of the annual accounts, appropriation of our profits and proposals relating to the composition of the management board or supervisory board, including the filling of any vacancies in the management board or supervisory board. In addition,

6

the agenda shall include such items as have been included therein by the management board or supervisory board. The agenda shall also include such items requested by one or more shareholders, and others entitled to attend general meetings of shareholders, representing at least 3% of the issued share capital. Requests must be made in writing and received by the management board at least 60 days before the day of the convocation of the meeting. No resolutions shall be adopted on items other than those which have been included in the agenda. In accordance with the Dutch Corporate Governance Code, or DCGC, a shareholder shall exercise the right of putting an item on the agenda only after consulting the management board in that respect. If one or more shareholders intend to request that an item be put on the agenda that may result in a change in the company’s strategy, pursuant to the DCGC the management board may invoke a response time of a maximum of 180 days until the day of the general meeting of shareholders. Next to the 180 days response time under the DCGC, as per May 1, 2021, a bill allowing the management board of a Dutch listed company a 250 days statutory response time took effect in the Netherlands. This response time may be invoked if (i) shareholders representing 3% of the issued share capital, request the board to put a proposal on the agenda of the general meeting to (a) appoint, suspend or dismiss members of the management board or supervisory board, or (b) amend the procedures laid down in the articles of association regarding the appointment, dismissal or suspension of a management board or supervisory board member or (ii) an unsolicited public offer is announced or made.

The general meeting is presided over by the chairman of the supervisory board. However, the chairman may charge another person to preside over the general meeting in his place even if he himself is present at the meeting. If the chairman of the supervisory board is absent and he has not charged another person to preside over the meeting in his place, the supervisory directors present at the meeting shall appoint one of them to be chairman. If no supervisory directors are present at the general meeting, the general meeting is to be presided over by one of the managing directors designated for that purpose by the management board. Managing directors and supervisory directors may attend a general meeting of shareholders. In these meetings, they have an advisory vote. The chairman of the meeting may decide at its discretion to admit other persons to the meeting.

All shareholders and others entitled to attend general meetings of shareholders are authorized to attend the general meeting of shareholders, to address the meeting and, in so far as they have such right, to vote.

Quorum and Voting Requirements

Each common share confers the right on the holder to cast one vote at the general meeting of shareholders. Shareholders may vote by proxy. No votes may be cast at a general meeting of shareholders on shares held by us or our subsidiaries or on shares for which we or our subsidiaries hold depositary receipts. Nonetheless, the holders of a right of use and enjoyment (vruchtgebruik) and the holders of a right of pledge in respect of shares held by us or our subsidiaries in our share capital are not excluded from the right to vote on such shares, if the right of use and enjoyment (vruchtgebruik) or the right of pledge was granted prior to the time such shares were acquired by us or any of our subsidiaries. Neither we nor any of our subsidiaries may cast votes in respect of a share on which we or such subsidiary holds a right of use and enjoyment (vruchtgebruik) or a right of pledge. Shares which are not entitled to voting rights pursuant to the preceding sentences will not be taken into account for the purpose of determining the number of shareholders that vote and that are present or represented, or the amount of the share capital that is provided or that is represented at a general meeting of shareholders.

Decisions of the general meeting of shareholders are taken by an absolute majority of votes cast, except where Dutch law or the Articles of Association provide for a qualified majority or unanimity.

Directors

Election of Directors

Under our Articles of Association, our managing directors and supervisory directors are appointed by the general meeting of shareholders upon a binding nomination by our supervisory board. The general meeting of shareholders may overrule the binding nomination by a resolution adopted with a two-thirds majority of the votes cast representing at least half of the issued share capital. If the general meeting of shareholders overrules the binding nomination, the supervisory board shall make a new binding nomination.

7

Duties and Liabilities of Directors

Under Dutch law, the management board is responsible for our management, strategy, policy and operations. The supervisory board is responsible for supervising the conduct of and providing advice to the management board and for supervising our business generally. Furthermore, each member of the management board and the supervisory board has a duty to act in the corporate interest of the company. Under Dutch law, the corporate interest extends to the interests of all corporate stakeholders, such as shareholders, creditors, employees, customers and suppliers. The duty to act in the corporate interest of the company also applies in the event of a proposed sale or break-up of the company, whereby the circumstances generally dictate how such duty is to be applied. Any resolution of the management board regarding a significant change in our identity or character requires shareholder approval.

Dividends and Other Distributions

Amount Available for Distribution

We may only make distributions to our shareholders if our shareholders’ equity exceeds the sum of the paid-in and called-up share capital plus the reserves as required to be maintained by Dutch law or by the Articles of Association.

Under the Articles of Association, the management board may resolve, subject to the approval of the supervisory board, to reserve the profits or part of the profits. After reservation by the management board of any profit, the remaining profit will be at the disposal of the general meeting of shareholders. We only make a distribution of dividends to our shareholders after the adoption of our annual accounts demonstrating that such distribution is legally permitted. The management board may resolve, with the approval of the supervisory board, to make interim distributions to the shareholders if an interim statement of assets and liabilities shows that Affimed’s shareholders’ equity exceeds the sum of the paid-up and called-up part of the capital and the reserves which must be maintained by Dutch law. Dividends and other distributions shall be made payable no later than thirty days after the date when they were declared, unless the corporate body authorized to declare the dividend determines a different date. Claims to dividends and other distributions not made within five years and one day after the date that such dividends or distributions became payable, shall be forfeited to us (verjaring) and shall be carried to the reserves. We do not anticipate paying any cash dividends for the foreseeable future.

Exchange Controls

Under existing laws of the Netherlands, there are no exchange controls applicable to the transfer to persons outside of the Netherlands of dividends or other distributions with respect to, or of the proceeds from the sale of, shares of a Dutch company.

Squeeze out Procedures

Pursuant to Section 92a, Book 2, Dutch Civil Code, a shareholder who for his own account holds at least 95% of our issued share capital may initiate proceedings against the other shareholders jointly for the transfer of their shares to such shareholder. The proceedings are held before the Enterprise Chamber of the Amsterdam Court of Appeal, or the Enterprise Chamber, and can be instituted by means of a writ of summons served upon each of the other shareholders in accordance with the provisions of the Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering). The Enterprise Chamber may grant the claim for squeeze out in relation to the other shareholders and will determine the price to be paid for the shares, if necessary after appointment of one or three experts who will offer an opinion to the Enterprise Chamber on the value to be paid for the shares of the other shareholders. Once the order to transfer becomes final before the Enterprise Chamber, the person acquiring the shares shall give written notice of the date and place of payment and the price to the holders of the shares to be acquired whose addresses are known to him. Unless the addresses of all of them are known to the acquiring person, such person is required to publish the same in a daily newspaper with a national circulation.

COMPARISON OF DUTCH LAW AND OUR ARTICLES OF ASSOCIATION AND

U.S. CORPORATE LAW

The following comparison between Dutch corporation law, which applies to us, and Delaware corporation law, the law under which many publicly listed corporations in the United States are incorporated, discusses additional matters not otherwise described in this prospectus. Although we believe this summary is materially accurate, the summary is subject to Dutch law, including Book 2 of the Dutch Civil Code and the DCGC and Delaware corporation law, including the Delaware General Corporation Law.

Corporate Governance

Duties of directors

The Netherlands. We have a two-tier board structure consisting of our supervisory board (raad van commissarissen) and a separate management board (raad van bestuur).

Under Dutch law, the management board is collectively responsible for the management and the strategy, policy and operations of the company. The supervisory board is responsible for supervising the conduct of and providing advice to the management board and for supervising the business generally. Furthermore, each member of the management board and the supervisory board has a duty to act in the corporate interest of the company and the business connected with it. Under Dutch law, the corporate interest extends to the interests of all corporate stakeholders, such as shareholders, creditors, employees, customers and suppliers. The duty to act in the corporate interest of the company also applies in the event of a proposed sale or break-up of the company, whereby the circumstances generally dictate how such duty is to be applied.

Delaware. The board of directors bears the ultimate responsibility for managing the business and affairs of a corporation. In discharging this function, directors of a Delaware corporation owe fiduciary duties of care and loyalty to the corporation and to its stockholders. Delaware courts have decided that the directors of a Delaware corporation are required to exercise informed business judgment in the performance of their duties. Informed business judgment means that the directors have informed themselves of all material information reasonably available to them. Delaware courts have also imposed a heightened standard of conduct upon directors of a Delaware corporation who take any action designed to defeat a threatened change in control of the corporation. In addition, under Delaware law, when the board of directors of a Delaware corporation approves the sale or break-up of a corporation, the board of directors may, in certain circumstances, have a duty to obtain the highest value reasonably available to the stockholders.

Director terms

The Netherlands. Managing directors and supervisory directors of a Dutch listed company are generally appointed for an individual term of a maximum of four years. There is no limit to the number of consecutive terms managing directors may serve. Following the DCGC, supervisory directors of a Dutch listed company are appointed for a period of four years and may then be reappointed once for another four-year period. The supervisory board member may then subsequently be reappointed for a period of two years, which appointment may be extended by at most two years.

Our managing directors are appointed by the general meeting of shareholders pursuant to a binding nomination by the supervisory board. The general meeting may at all times overrule the binding nomination by a resolution adopted by at least a two-thirds majority of the votes cast, representing more than one-half of the issued share capital. If the binding nomination is not overruled in accordance with the preceding sentence, the person proposed for appointment will have been appointed. If the general meeting overrules the binding nomination, the supervisory board shall make a new nomination.

Our supervisory directors are also appointed by the general meeting of shareholders upon a binding nomination by the supervisory board. The general meeting may at all times overrule the binding nomination by a

9

two-thirds majority of the votes cast, representing more than one-half of the issued share capital. If the binding nomination is not overruled in accordance with the preceding sentence, the person proposed for appointment will have been appointed. If the general meeting overrules the binding nomination, the supervisory board shall make a new nomination.

There are no restrictions on the number of reelections of our management directors. Pursuant to the Articles of Association, a supervisory director shall be appointed for a maximum term of four years, and may be reappointed for a term of not more than four years at a time. A supervisory director may be a supervisory director for a period not longer than twelve years, unless the general meeting of shareholders resolves otherwise. Under the DCGC, in the event of a reappointment of a supervisory director after he or she has served as supervisory director for eight years, the supervisory board report should include the reasons for such reappointment. As a result of our supervisory directors’ staggered four-year term of appointment, approximately one-fourth of our supervisory directors will be subject to election in any one year.

The general meeting of shareholders shall at all times be entitled to suspend or dismiss a member of the management board or supervisory board. The general meeting of shareholders may only adopt a resolution to suspend or dismiss such a member with a two-thirds majority of the votes cast, if such majority represents more than half of the issued share capital, unless the proposal was made by the supervisory board, in which case a simple majority is sufficient. The supervisory board may at all times suspend (but not dismiss) a member of the management board.

Delaware. The Delaware General Corporation Law generally provides for a one-year term for directors, but permits directorships to be divided into up to three classes with up to three-year terms, with the years for each class expiring in different years, if permitted by the certificate of incorporation, an initial bylaw or a bylaw adopted by the stockholders. A director elected to serve a term on a “classified” board may not be removed by stockholders without cause. There is no limit in the number of terms a director may serve.

Director vacancies

The Netherlands. Under Dutch law, new managing directors and supervisory directors are generally appointed by the general meeting of shareholders.

Under our Articles of Association, in case of a vacancy or vacancies of one or more managing directors, the remaining managing directors shall temporarily be in charge of the management, without prejudice to the right of the supervisory board to replace the managing director with a temporary managing director. In the case of a vacancy or vacancies of one or more supervisory directors, the remaining supervisory directors shall temporarily be in charge of the supervision, without prejudice to the right of the general meeting to appoint a temporary member of the supervisory board to replace the member of the supervisory board concerned.

Delaware. The Delaware General Corporation Law provides that vacancies and newly created directorships may be filled by a majority of the directors then in office (even though less than a quorum) unless (i) otherwise provided in the certificate of incorporation or bylaws of the corporation or (ii) the certificate of incorporation directs that a particular class of stock is to elect such director, in which case any other directors elected by such class, or a sole remaining director elected by such class, will fill such vacancy.

Conflict-of-interest transactions

The Netherlands. Pursuant to Dutch law and our Articles of Association, a managing director or a supervisory director shall not take part in the deliberations and the decision-making process of the management board or the supervisory board, as applicable, if he or she has a direct or indirect personal conflict of interest with the company or the business connected with it. Our Articles of Association provide that if as a result of the conflict of interest of managing directors no resolution of the management board can be adopted, the resolution is

10

adopted by the supervisory board. If as a result of the conflict of interest of supervisory directors no resolution of the supervisory board can be adopted, the resolution can nonetheless be adopted by the supervisory board. In that case, each supervisory board member is entitled to participate in the discussion and decision making process of the supervisory board and to cast a vote.

Delaware. The Delaware General Corporation Law generally permits transactions involving a Delaware corporation and an interested director of that corporation if:

Proxy voting by directors

The Netherlands. Under our Articles of Association, at a meeting of the management board, a managing director may only be represented by another managing director holding a written proxy. At a meeting of the supervisory board, a supervisory director may only be represented by another supervisory director holding a written proxy.

Delaware. A director of a Delaware corporation may not issue a proxy representing the director’s voting rights as a director.

Dutch Corporate Governance Code

The DCGC contains both principles and best practice provisions for management boards, supervisory boards, shareholders and general meetings of shareholders, financial reporting, auditors, disclosure, compliance and enforcement standards. A copy of the DCGC can be found on www.mccg.nl (which website is not incorporated by reference into this prospectus). As a Dutch company, we are subject to the DCGC and are required to disclose in our annual report, filed in the Netherlands, whether we comply with the provisions of the DCGC. If we do not comply with the provisions of the DCGC (for example, because of a conflicting Nasdaq requirement or otherwise), we must list the reasons for any deviation from the DCGC in our annual report. Our deviations from the DCGC are summarized below.

Shareholder rights

Voting rights

The Netherlands. In accordance with Dutch law and our Articles of Association, each issued common share confers the right to cast one vote at the general meeting of shareholders. Each holder of shares may cast as many votes as it holds shares. Shares that are held by us or our direct or indirect subsidiaries do not confer the right to vote.

In accordance with our Articles of Association, for each general meeting of shareholders, the management board may determine that a record date will be applied in order to establish which shareholders are entitled to attend and vote at the general meeting of shareholders. Such record date shall be the 28th day prior to the day of the general meeting. The record date and the manner in which shareholders can register and exercise their rights will be set out in the notice of the meeting.

Delaware. Under the Delaware General Corporation Law, each stockholder is entitled to one vote per share of stock, unless the certificate of incorporation provides otherwise. In addition, the certificate of incorporation may provide for cumulative voting at all elections of directors of the corporation, or at elections held under specified circumstances. Either the certificate of incorporation or the bylaws may specify the number of shares and/or the amount of other securities that must be represented at a meeting in order to constitute a quorum, but in no event will a quorum consist of less than one third of the shares entitled to vote at a meeting.

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 10 days before the date of the meeting, and if no record date is set then the record date is the close of business on the day next preceding the day on which notice is given, or if notice is waived then the record date is the close of business on the day next preceding the

12

day on which the meeting is held. The determination of the stockholders of record entitled to notice or to vote at a meeting of stockholders shall apply to any adjournment of the meeting, but the board of directors may fix a new record date for the adjourned meeting.

Shareholder proposals

The Netherlands. Pursuant to our Articles of Association and in accordance with Dutch law, general meetings of shareholders will be held whenever our supervisory board or management board deems such to be necessary. Pursuant to Dutch law, one or more shareholders representing at least ten percent of the issued capital may, on their application, be authorized by a Dutch district court to convene a general meeting of shareholders. The district court shall disallow the application if it does not appear that the applicants have previously requested the management board and the supervisory board to convene a general meeting of shareholders and neither the management nor the supervisory board has taken the necessary steps so that the general meeting of shareholders could be held within six weeks after the request.

Also, the agenda for a general meeting of shareholders shall include such items requested by one or more shareholders representing at least 3% of the issued share capital, except where the articles of association state a lower percentage. Our Articles of Association do not state such lower percentage. Requests must be made in writing and received by the management board at least 60 days before the day of the convocation of the meeting. In accordance with the DCGC, a shareholder shall exercise the right of putting an item on the agenda only after consulting the management board in that respect. If one or more shareholders intend to request that an item be put on the agenda that may result in a change in the company’s strategy, the management board may invoke a response time of a maximum of 180 days from the moment the management board is informed by one or more shareholders of their intention to put an item on the agenda to the day of the general meeting of shareholders at which the item is to be considered. Next to the 180 days response time under the DCGC, as per May 1, 2021, a bill allowing the management board of a Dutch listed company a 250 days statutory response time took effect in the Netherlands. This response time may be invoked if (i) shareholders representing 3% of the issued share capital, request the board to put a proposal on the agenda of the general meeting to (a) appoint, suspend or dismiss members of the management board or supervisory board, or (b) amend the procedures laid down in the articles of association regarding the appointment, dismissal or suspension of a management board or supervisory board member or (ii) an unsolicited public offer is announced or made.

Delaware. Delaware law does not specifically grant stockholders the right to bring business before an annual or special meeting. However, if a Delaware corporation is subject to the SEC’s proxy rules, a stockholder who owns at least $2,000 in market value, or 1% of the corporation’s securities entitled to vote, and has owned such securities for at least one year, may propose a matter for a vote at an annual or special meeting in accordance with those rules.

Action by written consent

The Netherlands. Under Dutch law, resolutions of the general meeting of shareholders of a Dutch public limited liability company may be adopted in writing without holding a meeting of shareholders, provided that (i) the articles of association allow such action by written consent and (ii) the resolution is adopted unanimously by all shareholders that are entitled to vote. The requirement of unanimity renders the adoption of shareholder resolutions without holding a meeting not feasible for publicly traded companies. Therefore, our Articles of Association do not provide for shareholder action by written consent.

Delaware. Although permitted by Delaware law, publicly listed companies do not typically permit stockholders of a corporation to take action by written consent.

Appraisal rights

The Netherlands. The concept of appraisal rights is not known as such under Dutch law.

13

However, in accordance with the directive 2005/56/EC of the European Parliament and the Council of 26 October 2005 on cross-border mergers of limited liability companies, Dutch law provides that, to the extent that the acquiring company in a cross-border merger is organized under the laws of another EU member state, a shareholder of a Dutch disappearing company who has voted against the cross-border merger may file a claim with the Dutch company for compensation. Such compensation is to be determined by one or more independent experts. The independent experts will take into account any provisions in the articles of association or agreements between the company and shareholders concerning the determination of the fair value of shares and the compensation to be paid to shareholders demanding their shares to be acquired at fair value. If the articles of association or an agreement between the company and the shareholders contains criteria for the unequivocal determination of the fair value of shares and the compensation to be paid to shareholders demanding their shares to be acquired at fair value, no independent experts are required to be appointed. The shares of such shareholder that are subject to such appraisal claim will cease to exist as of the moment of effectiveness of the cross-border merger. If the acquiring company is a company incorporated under the laws of another member state of the European Union or the European Economic Area, the Dutch notary may only issue a declaration stating that the pre-merger formalities have been complied with if no appraisal claim has been filed, the compensation shareholders have been demanding has been paid or the other merging companies have decided that the acquiring company must pay the compensation due to shareholders.

Delaware. The Delaware General Corporation Law provides for stockholder appraisal rights, or the right to demand payment in cash of the judicially determined fair value of the stockholder’s shares, in connection with certain mergers and consolidations.

Shareholder suits

The Netherlands. In the event a third party is liable to a Dutch company, only the company itself can bring a civil action against that party. The individual shareholders do not have the right to bring an action on behalf of the company. Only in the event that the cause for the liability of a third party to the company also constitutes a tortious act directly against a shareholder does that shareholder have an individual right of action against such third party in its own name. The DCC provides for the possibility to initiate such actions collectively. A foundation or an association whose objective is to protect the rights of a group of persons having similar interests can institute a collective action if such representative organization meets certain statutory criteria. Until recently a collective action could only result in a declaratory judgment (verklaring voor recht). In order to obtain compensation for damages, the foundation or association and the defendant may reach—for instance, on the basis of such declaratory judgment—a settlement. Pursuant to the Dutch Act on the Collective Settlement of Mass Claims (the “WCAM”), a Dutch court may declare the settlement agreement binding upon all the injured parties with an opt-out choice for an individual injured party. However, as of January 1, 2020, new legislation allows Dutch courts to award monetary damages in class action cases. The new legislation encourages parties to explore the options of a collective settlement pending the class action. The new legislation also introduces higher thresholds for class actions and statutory criteria on the basis of which representative organizations can only bring a collective claim before the Dutch courts if they, inter alia, have sufficient expertise on the matter brought before the court, their governance meets certain threshold criteria and are sufficiently funded and transparent concerning their funding. The new legislation also contains stricter rules with regard to the jurisdiction of the Dutch courts. A class action will only be admissible if it has a sufficiently substantive connection with the Netherlands. This will be the case if the majority of the claimants are based in the Netherlands, the defendant is domiciled in the Netherlands or where the unlawful event took place in the Netherlands. Finally, class actions under the new legislation will, as a rule, only apply to injured Dutch parties that have not chosen to opt-out of the class action. Foreign plaintiffs will, in principle, only be bound by the outcome of the class action proceedings if they explicitly opt-in. If a settlement is reached during the proceedings, there is an additional possibility for an injured party to opt-out. This is different than under the WCAM (see above), which does not feature an opt-in for foreign injured parties. If a settlement is declared binding by the Dutch courts pursuant to the WCAM, all intended beneficiaries are bound by the settlement unless they opt-out. An individual injured party may also itself—outside the collective action—institute a civil claim for damages.

14

Delaware. Under the Delaware General Corporation Law, a stockholder may bring a derivative action on behalf of the corporation to enforce the rights of the corporation. An individual also may commence a class action suit on behalf of himself and other similarly situated stockholders where the requirements for maintaining a class action under Delaware law have been met. A person may institute and maintain such a suit only if that person was a stockholder at the time of the transaction which is the subject of the suit. In addition, under Delaware case law, the plaintiff normally must be a stockholder at the time of the transaction that is the subject of the suit and throughout the duration of the derivative suit. Delaware law also requires that the derivative plaintiff make a demand on the directors of the corporation to assert the corporate claim before the suit may be prosecuted by the derivative plaintiff in court, unless such a demand would be futile.

Repurchase of shares

The Netherlands. Under Dutch law, when issuing shares, a public company with limited liability such as ours may not subscribe for newly issued shares in its own capital. Such company may, however, subject to certain restrictions of Dutch law and its articles of association, acquire shares in its own capital. A listed public company with limited liability may acquire fully paid shares in its own capital at any time for no valuable consideration. Furthermore, subject to certain provisions of Dutch law and its articles of association, such company may repurchase fully paid shares in its own capital if (i) the company’s shareholders’ equity less the payment required to make the acquisition does not fall below the sum of paid-up and called-up capital and any reserves required by Dutch law or its articles of association and (ii) the company and its subsidiaries would not thereafter hold shares or hold a pledge over shares with an aggregate par value exceeding 50% of its then current issued share capital. Such company may only acquire its own shares if its general meeting of shareholders has granted the management board the authority to effect such acquisitions.

An acquisition of common shares for a consideration must be authorized by our general meeting of shareholders. Such authorization may be granted for a maximum period of 18 months and must specify the number of common shares that may be acquired, the manner in which common shares may be acquired and the price limits within which common shares may be acquired. Authorization is not required for the acquisition of common shares in order to transfer them to our employees. The actual acquisition may only be effected by a resolution of our management board. At the general meeting held on June 15, 2021, the general meeting of shareholders authorized our management board acting with the approval of our supervisory board, for a period of 18 months (until December 15, 2022) to cause the repurchase of common shares by us of up to 10% of our issued share capital, for a price per share not exceeding 110% of the most recent closing price of a common share on any stock exchange where the common shares are listed.

No authorization of the general meeting of shareholders is required if common shares are acquired by us with the intention of transferring such common shares to our employees under an applicable employee stock purchase plan.

If we would decide to repurchase any of our shares, no votes could be cast at a general meeting of shareholders on the shares held by us or our subsidiaries or on shares for which we or our subsidiaries hold depositary receipts. Nonetheless, the holders of a right of use and enjoyment (vruchtgebruik) and the holders of a right of pledge in respect of shares held by us or our subsidiaries in our share capital are not excluded from the right to vote on such shares, if the right of use and enjoyment (vruchtgebruik) or the right of pledge was granted prior to the time such shares were acquired by us or any of our subsidiaries. Neither we nor any of our subsidiaries may cast votes in respect of a share on which we or such subsidiary holds a right of use and enjoyment (vruchtgebruik) or a right of pledge.

Delaware. Under the Delaware General Corporation Law, a corporation may purchase or redeem its own shares unless the capital of the corporation is impaired or the purchase or redemption would cause an impairment of the capital of the corporation. A Delaware corporation may, however, purchase or redeem out of capital any of its preferred shares or, if no preferred shares are outstanding, any of its own shares if such shares will be retired upon acquisition and the capital of the corporation will be reduced in accordance with specified limitations.

15

Anti-Takeover Provisions

The Netherlands. Under Dutch law, various protective measures are possible and permissible within the boundaries set by Dutch law and Dutch case law. We have adopted several provisions that may have the effect of making a takeover of our company more difficult or less attractive, including:

Delaware. In addition to other aspects of Delaware law governing fiduciary duties of directors during a potential takeover, the Delaware General Corporation Law also contains a business combination statute that protects Delaware companies from hostile takeovers and from actions following the takeover by prohibiting some transactions once an acquirer has gained a significant holding in the corporation.

Section 203 of the Delaware General Corporation Law prohibits “business combinations,” including mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with an interested stockholder that beneficially owns 15% or more of a corporation’s voting stock, within three years after the person becomes an interested stockholder, unless:

A Delaware corporation may elect not to be governed by Section 203 by a provision contained in the original certificate of incorporation of the corporation or an amendment to the original certificate of incorporation or to the bylaws of the company, which amendment must be approved by a majority of the shares entitled to vote and may not be further amended by the board of directors of the corporation. In most cases, such an amendment is not effective until twelve months following its adoption.

Inspection of Books and Records

The Netherlands. The management board and the supervisory board provide the general meeting of shareholders in good time with all information that the shareholders require for the exercise of their powers, unless this would be contrary to an overriding interest of us.

16

Delaware. Under the Delaware General Corporation Law, any stockholder may inspect for any proper purpose certain of the corporation’s books and records during the corporation’s usual hours of business.

Removal of Directors

The Netherlands. Under our Articles of Association, the general meeting of shareholders shall at all times be entitled to suspend or dismiss a member of the management board or supervisory board. The general meeting of shareholders may only adopt a resolution to suspend or dismiss such a member by at least a two-thirds majority of the votes cast, if such majority represents more than half of the issued share capital, unless the proposal was made by the supervisory board in which case a simple majority is sufficient.

Delaware. Under the Delaware General Corporation Law, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except (i) unless the certificate of incorporation provides otherwise, in the case of a corporation whose board is classified, stockholders may effect such removal only for cause, or (ii) in the case of a corporation having cumulative voting, if less than the entire board is to be removed, no director may be removed without cause if the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire board of directors, or, if there are classes of directors, at an election of the class of directors of which he is a part.

Preemptive Rights

The Netherlands. Under Dutch law, upon the issue of common shares, each holder of common shares shall have a preemptive right to acquire such newly issued shares in proportion to the aggregate amount of such holder’s common shares, it being understood that this preemptive right shall not apply to (i) the issuance of shares to employees of the company or employees of a group company; and (ii) the issuance of shares against payment in kind.

Under our Articles of Association, if and insofar as the management board is not authorized to limit or exclude pre-emptive rights, the preemptive rights in respect of newly issued common shares may be restricted or excluded by a resolution of the general meeting of shareholders upon proposal of the management board, which proposal has been approved by the supervisory board. The management board, subject to approval of the supervisory board, may also resolve to restrict or exclude the preemptive rights in respect of newly issued common shares if it has been designated as the authorized body to do so by the general meeting of shareholders. Such designation can be granted for a period not exceeding five years. A resolution of the general meeting of shareholders to restrict or exclude the preemptive rights or to designate the management board as the authorized body to do so requires a majority of not less than two-thirds of the votes cast, if less than one-half of our issued share capital is represented at the meeting.

At a general meeting held on June 25, 2019, the general meeting of shareholders authorized our management board, subject to the approval of our supervisory board, for a period of five years from the date of the meeting (up to and including June 25, 2024) to restrict or exclude pre-emptive rights accruing to shareholders in connection with the issue of common shares and/or rights to subscribe for common shares in relation to any issuance or granting of rights to subscribe for common shares in the share capital of Affimed, up to the maximum number of common shares that can be issued under the size of the authorized share capital of Affimed as per the date of adoption of such resolution.

Delaware. Under the Delaware General Corporation Law, stockholders have no preemptive rights to subscribe for additional issues of stock or to any security convertible into such stock unless, and to the extent that, such rights are expressly provided for in the certificate of incorporation.

17

Dividends

The Netherlands. Dutch law provides that dividends may be distributed after adoption of the annual accounts by the general meeting of shareholders from which it appears that such dividend distribution is allowed. Moreover, dividends may be distributed only to the extent the shareholders’ equity exceeds the amount of the paid-up and called-up part of the issued share capital and the reserves that must be maintained under the law or the articles of association. Interim dividends may be declared as provided in the articles of association and may be distributed to the extent that the shareholders’ equity exceeds the amount of the issued and paid-up and called-up part of the issued share capital and the required legal reserves as described above as apparent from our financial statements.

Under the Articles of Association, the management board may resolve, subject to the approval of the supervisory board, to reserve the profits or part of the profits. After reservation by the management board of any profit, the remaining profit will be at the disposal of the general meeting of shareholders. We only make a distribution of dividends to our shareholders after the adoption of our annual accounts demonstrating that such distribution is legally permitted. The management board may resolve, with the approval of the supervisory board, to make interim distributions to the shareholders if an interim statement of assets and liabilities shows that Affimed’s shareholders’ equity exceeds the sum of the paid-up and called-up part of the capital and the reserves which must be maintained by Dutch law.

Dividends and other distributions shall be made payable no later than thirty days after the date when they were declared, unless the corporate body authorized to declare the dividend determines a different date. Claims to dividends and other distribution not made within five years from the date that such dividends or distributions became payable, shall be forfeited to us (verjaring) and shall be carried to the reserves.

Delaware. Under the Delaware General Corporation Law, a Delaware corporation may pay dividends out of its surplus (the excess of net assets over capital), or in case there is no surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year (provided that the amount of the capital of the corporation is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets). In determining the amount of surplus of a Delaware corporation, the assets of the corporation, including stock of subsidiaries owned by the corporation, must be valued at their fair market value as determined by the board of directors, without regard to their historical book value. Dividends may be paid in the form of common stock, property or cash.

Shareholder Vote on Certain Reorganizations

The Netherlands. Under Dutch law, the general meeting of shareholders must approve resolutions of the management board relating to a significant change in the identity or the character of the company or the business of the company, which includes:

Delaware. Under the Delaware General Corporation Law, the vote of a majority of the outstanding shares of capital stock entitled to vote thereon generally is necessary to approve a merger or consolidation or the sale of all or substantially all of the assets of a corporation. The Delaware General Corporation Law permits a corporation

18

to include in its certificate of incorporation a provision requiring for any corporate action the vote of a larger portion of the stock or of any class or series of stock than would otherwise be required.

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 (i) the agreement of merger does not amend in any respect the certificate of incorporation of the surviving corporation, (ii) the shares of stock of the surviving corporation are not changed in the merger and (iii) 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.

Remuneration of Directors

The Netherlands. Under Dutch law and our Articles of Association, we must adopt a remuneration policy for our managing directors. Such remuneration policy shall be adopted by the general meeting of shareholders upon the proposal of the supervisory board. The supervisory board determines the remuneration of the management board in accordance with the remuneration policy. A proposal with respect to remuneration schemes in the form of shares or rights to shares must be submitted to the general meeting of shareholders for its approval.

The general meeting may determine the remuneration of supervisory directors. The supervisory directors shall be reimbursed for their expenses.

Delaware. Under the Delaware General Corporation Law, the stockholders do not generally have the right to approve the compensation policy for directors or the senior management of the corporation, although certain aspects of executive compensation may be subject to stockholder vote due to the provisions of U.S. federal securities and tax law, as well as exchange requirements.

19

DESCRIPTION OF DEBT SECURITIES

The debt securities will be our direct general obligations. The debt securities will be either senior debt securities or subordinated debt securities and may be secured or unsecured and may be convertible into other securities, including our common shares. The debt securities will be issued under one or more separate indentures between our company and a financial institution that will act as trustee. Senior debt securities will be issued under a senior indenture. Subordinated debt securities will be issued under a subordinated indenture. Each of the senior indenture and the subordinated indenture is referred to individually as an indenture and collectively as the indentures. Each of the senior debt trustee and the subordinated debt trustee is referred to individually as a trustee and collectively as the trustees. The material terms of any indenture will be set forth in the applicable prospectus supplement.

We have summarized certain terms and provisions of the indentures. The summary is not complete. The indentures are subject to and governed by the Trust Indenture Act of 1939, as amended. The senior indenture and subordinated indenture are substantially identical, except for the provisions relating to subordination.

Neither indenture will limit the amount of debt securities that we may issue. We may issue debt securities up to an aggregate principal amount as we may authorize from time to time. The applicable prospectus supplement will describe the terms of any debt securities being offered. These terms will include some or all of the following:

20

Senior Debt

We may issue under the senior indenture the debt securities that will constitute part of our senior debt. These senior debt securities will rank equally and pari passu with all our other unsecured and unsubordinated debt.

Subordinated Debt

We may issue under the subordinated indenture the debt securities that will constitute part of our subordinated debt. These subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner set forth in the subordinated indenture, to all our “senior indebtedness.” “Senior indebtedness” is defined in the subordinated indenture and generally includes obligations of, or guaranteed by, us for borrowed money, or as evidenced by bonds, debentures, notes or other similar instruments, or in respect of letters of credit or other similar instruments, or to pay the deferred purchase price of property or services, or as a lessee under capital leases, or as secured by a lien on any asset of ours. “Senior indebtedness” does not include the subordinated debt securities or any other obligations specifically designated as being subordinate in right of payment to, or pari passu with, the subordinated debt securities. In general, the holders of all senior indebtedness are first entitled to receive payment in full of such senior indebtedness before the holders of any of the subordinated debt securities are entitled to receive a payment on account of the principal or interest on the indebtedness evidenced by the subordinated debt securities in certain events. These events include:

Authentication and Delivery

We will deliver the debt securities to the trustee for authentication, and the trustee will authenticate and deliver the debt securities upon our written order.

Events of Default

When we use the term “Event of Default” in the indentures with respect to the debt securities of any series, set forth below are some examples of what we mean:

21

If an Event of Default (other than an Event of Default specified in clause (4) above) with respect to the debt securities of any series then outstanding occurs and is continuing, then either the trustee or the holders of not less than 25% in principal amount of the securities of all such series then outstanding in respect of which an Event of Default has occurred may by notice in writing to us declare the entire principal amount of all debt securities of the affected series, and accrued interest, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable.

If an Event of Default described in clause (4) above occurs and is continuing, then the principal amount of all the debt securities then outstanding and accrued interest shall be and become due immediately and payable without any declaration, notice or other action by any holder of the debt securities or the trustee.

The trustee will, within 90 days after the occurrence of any default actually known to it, give notice of the default to the holders of the debt securities of that series, unless the default was already cured or waived. Unless there is a default in paying principal or interest when due, the trustee can withhold giving notice to the holders if it determines in good faith that the withholding of notice is in the interest of the holders.

Satisfaction, Discharge and Defeasance

We may discharge our obligations under each indenture, except as to:

when:

22

In addition, unless the applicable prospectus supplement and supplemental indenture otherwise provide, we may elect either (i) to have our obligations under each indenture discharged with respect to the outstanding debt securities of any series (“legal defeasance”) or (ii) to be released from our obligations under each indenture with respect to certain covenants applicable to the outstanding debt securities of any series (“covenant defeasance”). Legal defeasance means that we will be deemed to have paid and discharged the entire indebtedness represented by the outstanding debt securities of such series under such indenture and covenant defeasance means that we will no longer be required to comply with the obligations with respect to such covenants (and an omission to comply with such obligations will not constitute a default or event of default).

In order to exercise legal defeasance or covenant defeasance with respect to outstanding debt securities of any series:

in each case sufficient without reinvestment, in the written opinion of a nationally recognized firm of independent public accountants, to pay and discharge, and which shall be applied by the trustee to pay and discharge, all of the principal and interest at due date or maturity or if we have made irrevocable arrangements satisfactory to the trustee for the giving of notice of redemption by the trustee, the redemption date;

We are required to furnish to each trustee an annual statement as to compliance with all conditions and covenants under the indenture.

23

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt securities, common shares or other securities. We may issue warrants independently or together with other securities. Warrants sold with other securities may be attached to or separate from the other securities. We will issue warrants under one or more warrant agreements between our company and a warrant agent that we will name in the applicable prospectus supplement.

The prospectus supplement relating to any warrants we offer will include specific terms relating to the offering. These terms will include some or all of the following:

The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

24

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of debt or equity securities issued by us or securities of third parties, a basket of such securities, an index or indices or such securities or any combination of the above as specified in the applicable prospectus supplement.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under either the senior indenture or the subordinated indenture.

25

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more common shares, debt securities, warrants, purchase contracts or any combination of such securities. The applicable prospectus supplement will describe:

26

FORMS OF SECURITIES

Each debt security, warrant and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

We may issue the registered debt securities, warrants and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security

27

desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of Affimed N.V., its affiliates, the trustees, the warrant agents, the unit agents or any other agent of Affimed N.V., agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

We may sell the securities in one or more of the following ways (or in any combination) from time to time:

The prospectus supplement will state the terms of the offering of the securities, including:

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If underwriters are used in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

The securities may be sold through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions paid to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

Sales to or through one or more underwriters or agents in at-the-market offerings will be made pursuant to the terms of a distribution agreement with the underwriters or agents. Such underwriters or agents may act on an agency basis or on a principal basis. During the term of any such agreement, shares may be sold on a daily basis on any stock exchange, market or trading facility on which the common shares are traded, in privately negotiated transactions or otherwise as agreed with the underwriters or agents. The distribution agreement will provide that

29

any common share sold will be sold at negotiated prices or at prices related to the then prevailing market prices for our common shares. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, we may also agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common shares or other securities. The terms of each such distribution agreement will be described in a prospectus supplement.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions paid for solicitation of these contracts.

Underwriters and agents may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters or agents may be required to make.

The prospectus supplement may also set forth whether or not underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the securities at levels above those that might otherwise prevail in the open market, including, for example, by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids.

Underwriters and agents may be customers of, engage in transactions with, or perform services for us and our affiliates in the ordinary course of business.

Each series of securities will be a new issue of securities and will have no established trading market, other than our common shares, which are listed on The Nasdaq Global Market. Any underwriters to whom securities are sold for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The securities, other than our common shares, may or may not be listed on a national securities exchange.

31

ENFORCEMENT OF CIVIL LIABILITIES

We are incorporated under the laws of the Netherlands and our headquarters are located in Germany. Substantially all of our assets are located outside the United States. The majority of our managing directors and supervisory directors reside outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce against them or us in U.S. courts, including judgments predicated upon the civil liability provisions of the federal securities laws of the United States.

The United States and the Netherlands currently do not have a treaty providing for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in the Netherlands. In order to obtain a judgment which is enforceable in the Netherlands, the party in whose favor a final and conclusive judgment of the U.S. court has been rendered will be required to file its claim with a court of competent jurisdiction in the Netherlands. Such party may submit to the Dutch court the final judgment rendered by the U.S. court. If and to the extent that the Dutch court finds that the jurisdiction of the U.S. court has been based on grounds which are internationally acceptable, that the proceedings before the U.S. court complied with principles of proper procedures, that recognition and/or enforcement of such judgment would not contravene the public policy of the Netherlands, and that recognition and/or enforcement of the judgment is not irreconcilable with a decision of a Dutch court rendered between the same parties or with an earlier decision of a foreign court rendered between the same parties in a dispute that is about the same subject matter and that is based on the same cause, provided that earlier judgment can be recognized in the Netherlands, the court of the Netherlands will, in principle, give binding effect to the judgment of the U.S. court. A Dutch court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages, and refuse to award punitive damages if that would contravene public policy of the Netherlands. In addition, there is doubt as to whether a Dutch court would impose civil liability on us, our managing directors or supervisory directors or certain experts named herein in an original action predicated solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in the Netherlands against us or such directors or experts, respectively. Enforcement and recognition of judgments of U.S. courts in the Netherlands are solely governed by the provisions of the Dutch Civil Procedure Code.

The United States and Germany currently do not have a treaty providing for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in Germany. German courts may deny the recognition and enforcement of a judgment rendered by a U.S. court if they consider the U.S. court not to be competent or the decision not in line with German public policy principles. For example, recognition of court decisions based on class actions brought in the United States typically raises public policy concerns and judgments awarding punitive damages are generally not enforceable in Germany.

In addition, actions brought in a German court against us, our managing directors or supervisory directors, our senior management and the experts named herein to enforce liabilities based on U.S. federal securities laws may be subject to certain restrictions. In particular, German courts generally do not award punitive damages. Litigation in Germany is also subject to rules of procedure that differ from the U.S. rules, including with respect to the taking and admissibility of evidence, the conduct of the proceedings and the allocation of costs. Proceedings in Germany would have to be conducted in the German language and all documents submitted to the court would, in principle, have to be translated into German. For these reasons, it may be difficult for a U.S. investor to bring an original action in a German court predicated upon the civil liability provisions of the U.S. federal securities laws against us, our managing directors or supervisory directors, our senior management and the experts named in this prospectus.

32

Based on the lack of a treaty as described above, U.S. investors may not be able to enforce against us or managing directors or supervisory directors, officers or certain experts named herein who are residents of the Netherlands, Germany, or other countries other than the United States any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.

33

LEGAL MATTERS

The validity of the common shares and certain other matters of Dutch law will be passed upon for us by De Brauw Blackstone Westbroek N.V. Certain matters of U.S. federal and New York State law will be passed upon for us by Kirkland and Ellis LLP, New York, New York.

PROSPECTUS SUPPLEMENT

(To Prospectus dated March 31, 2022)

$100,000,000

Common Shares

We have previously entered into an Open Market Sale Agreement^SM, or sale agreement, with Jefferies LLC, or Jefferies, dated November 10, 2021, relating to the sale of our common shares offered by this prospectus supplement. In accordance with the terms of the sale agreement, under this prospectus supplement we may offer and sell our common shares, nominal value €0.01 per share, having an aggregate offering price of up to $100,000,000 from time to time through Jefferies, acting as our agent. As of February 24, 2022, we have sold $1,882,658 of our common shares under the Open Market Sale Agreement.

Sales of our common shares, if any, under this prospectus supplement will be made by any method permitted that is deemed an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended, or the Securities Act, including sales made directly on or through The Nasdaq Global Market, or Nasdaq, the existing trading market for our common shares, sales made to or through a market maker other than on an exchange or otherwise, in negotiated transactions at market prices, and/or any other method permitted by law. Jefferies is not required to sell any specific amount, but will act as our sales agent using commercially reasonable efforts consistent with its normal trading and sales practices. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

Jefferies will be entitled to compensation at a commission rate of up to 3.00% of the gross sales price per share sold under the sale agreement. See “Plan of Distribution” beginning on page S-21 for additional information regarding the compensation to be paid to Jefferies.

In connection with the sale of the common shares on our behalf, Jefferies may be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Jefferies may be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to Jefferies with respect to certain liabilities, including liabilities under the Securities Act.

Our common shares trade on The Nasdaq Global Market, or Nasdaq, under the trading symbol “AFMD.” On March 30, 2022, the last sale price of our common shares as reported on Nasdaq was $4.28 per share.

Investing in our common shares involves a high degree of risk. See “Risk Factors” beginning on page S-6 of this prospectus supplement and in the documents incorporated by reference herein.

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

ABOUT THIS PROSPECTUS SUPPLEMENT

This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying prospectus, which is part of a registration statement that we filed with the SEC using a “shelf” registration process. The accompanying prospectus describes more general information, some of which may not apply to this offering. Under this shelf registration process, we may from time to time sell our common shares under a prospectus supplement at prices and on terms to be determined by market conditions at the time of the offering.

Before buying any of the common shares that we are offering, we urge you to carefully read both this prospectus supplement and the accompanying prospectus together with all of the information incorporated by reference herein, as well as the additional information described under the headings “Where You Can Find More Information” and “Incorporation by Reference.” These documents contain important information that you should consider when making your investment decision.

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 in any document incorporated by reference in this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement, provided that if any statement in one of these documents is inconsistent with a statement in another document having a later date—for example, a document incorporated by reference in this prospectus supplement—the statement in the document having the later date modifies or supersedes the earlier statement.

We have not authorized anyone to provide any information other than that contained in or incorporated by reference in this prospectus supplement and any related free writing prospectus filed by us with the SEC. We have not, and Jefferies has not, authorized anyone to provide you with different information. We take no responsibility for, and can provide no assurance as to the reliability of any other information that others may give you. This prospectus supplement does not constitute an offer to sell or the solicitation of an offer to buy any securities other than the securities described in this prospectus supplement or an offer to sell or the solicitation of an offer to buy such securities in any circumstances in which such offer or solicitation is unlawful. You should assume that the information appearing in this prospectus supplement, the documents incorporated by reference and any related free writing prospectus is accurate only as of their respective dates. Our business, financial condition, results of operations and prospects may have changed materially since those dates.

You should also read and consider the information in the documents to which we have referred you in the sections entitled “Where You Can Find More Information” and “Incorporation by Reference” in this prospectus supplement.

Unless otherwise indicated or the context otherwise requires, all references in this prospectus supplement to “Affimed N.V.,” “Affimed,” the “Company,” “we,” “our,” “ours,” “us” or similar terms refer to Affimed N.V.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the financial statements and other documents incorporated by reference in this prospectus supplement contain forward-looking statements, including statements concerning our industry, our operations, our anticipated financial performance and financial condition, and our business plans and growth strategy and product development efforts. These statements constitute 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 Exchange Act. Many of the forward-looking statements contained in this prospectus supplement can be identified by the use of forward-looking words such as “anticipate,” “believe,” “could,” “expect,” “should,” “plan,” “intend,” “estimate” and “potential,” among others. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates. These forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain and subject to a number of risks and uncertainties.

The following represent some, but not necessarily all, of the factors that could cause actual results to differ from historical results or those anticipated or predicted by our forward-looking statements:

S-iv

Our actual results or performance could differ materially from those expressed in, or implied by, any forward-looking statements relating to those matters. Accordingly, no assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do, what impact they will have on our results of operations, cash flows or financial condition. Additionally, some of the risks and uncertainties identified above may be amplified by the COVID-19 pandemic. It is not possible to predict or identify all such risks. There may be additional risks that we consider immaterial or which are unknown. Except as required by law, we are under no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise.

RISK FACTORS

You should carefully consider the risks and uncertainties described below, as well as those risks and uncertainties identified in the documents incorporated by reference herein, including our most recent Annual Report on Form 20-F, before making an investment in our common shares. Our business, financial condition or results of operations could be materially and adversely affected if any of these risks occurs, and as a result, the market price of our common shares could decline and you could lose all or part of your investment. This prospectus supplement also contains forward-looking statements that involve risks and uncertainties. See “Cautionary Statement Regarding Forward-Looking Statements.” Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors.

Risks Related to this Offering

Future sales, or the possibility of future sales, of a substantial number of our common shares could adversely affect the price of the shares and dilute shareholders.

Future sales of a substantial number of our common shares, or the perception that such sales will occur, could cause a decline in the market price of our common shares. Pursuant to the at-the-market program, and potentially other offerings, we plan to continue to raise money to fund our operations through the issuance of our equity securities. If our existing shareholders sell substantial amounts of common shares in the public market, or the market perceives that such sales may occur, the market price of our common shares and our ability to raise capital through an issue of equity securities in the future could be adversely affected. In addition, we have registered on a Form S-8 registration statement all common shares that we may issue under our equity compensation plans. As a result, these shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates.

If we sell common shares, convertible securities or other equity securities, existing shareholders may be diluted by such sales, and in certain cases new investors could gain rights superior to our existing shareholders. Any sales of our common shares, or the perception that such sales could occur, could have a negative impact on the trading price of our shares.

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

The public offering price of our common shares may exceed the as adjusted net tangible book value per common share. Therefore, if you purchase common shares in this offering, you may pay a price per common share that substantially exceeds our as adjusted net tangible book value per common share after this offering. To the extent outstanding options or warrants are exercised, you will incur further dilution.

Assuming that an aggregate of 16,051,364 of our common shares are sold at a price of $6.23 per share pursuant to this prospectus supplement, which was the last reported sale price of our common shares on Nasdaq on November 9, 2021, for aggregate gross proceeds of $100 million, after deducting commissions and estimated aggregate offering expenses payable by us, you would experience immediate dilution of $4.39 per common share, representing the difference between our as adjusted net tangible book value per common share as of September 30, 2021, after giving effect to this offering and the assumed offering price.

It is possible that we may be a PFIC in 2021 or one or more future taxable years. A U.S. investor may suffer adverse U.S. federal income tax consequences if we are a PFIC for any taxable year during which the U.S. investor holds common shares.

Under the Internal Revenue Code of 1986, as amended, or the Code, we will be a PFIC for any taxable year in which, after the application of certain “look-through” rules with respect to subsidiaries, either (i) 75% or more of our gross income consists of “passive income,” or (ii) 50% or more of the average quarterly value of our assets consist of assets that produce, or are held for the production of, “passive income.” Although we have not performed a definitive PFIC analysis using U.S. federal income tax principles, based on certain estimates as to composition of our income and assets, including the implied value, based on our market capitalization, of our

S-6

assets that produce non-passive income, in 2021 to date, it is possible that we would be treated as a PFIC with respect to 2021. Passive income generally includes, among other things, interest, dividends, certain non-active rents and royalties and capital gains. Whether we will be a PFIC in 2021 or any future taxable year is uncertain because, among other things, we currently own a substantial amount of passive assets, including cash, and because the valuation of our assets that generate non-passive income for PFIC purposes, including our intangible assets, is uncertain and may vary substantially over time. In addition, the composition of our assets and income may vary substantially over time. The average quarterly value of our assets for purposes of determining our PFIC status for any taxable year will generally be determined in part by reference to our market capitalization, which has fluctuated and may continue to fluctuate significantly over time. Accordingly, there can be no assurance that we will not be a PFIC in 2021 or for any future taxable year. In addition, we may, directly or indirectly, hold equity interests in other entities, including certain of our subsidiaries that are PFICs, or “Lower-tier PFICs.”

If we are a PFIC for any taxable year during which a U.S. investor holds common shares, we generally will continue to be treated as a PFIC with respect to that U.S. investor for all succeeding years during which the U.S. investor holds common shares, even if we cease to meet the threshold requirements for PFIC status. Such a U.S. investor may be subject to adverse tax consequences, including (i) the treatment of all or a portion of any gain on disposition as ordinary income, (ii) the application of a deferred interest charge on such gain and the receipt of certain dividends and (iii) compliance with certain reporting requirements. To avoid the application of the foregoing rules, a U.S. investor can make an election to treat us and each Lower-tier PFIC as a qualified electing fund (a “QEF Election”) in the first taxable year that we and each Lower-tier PFIC are treated as PFICs with respect to the U.S. investor. We currently intend to provide the information necessary for a U.S. investor to make a QEF Election with respect to us and each Lower-tier PFIC that we control for 2021 and for any future years with respect to which we determine that we or any Lower-tier PFIC that we control are or are likely to be a PFIC. A U.S. investor can also avoid certain of the adverse U.S. federal income tax consequences described above by making a mark-to-market election with respect to its common shares, provided that the common shares are “marketable.” U.S. investors should consult their tax advisers regarding the availability and advisability of making a QEF Election or a mark-to-market election in their particular circumstances. See “Material U.S. Federal Income Tax Considerations” for further information regarding the consequences to a U.S. investor if we are a PFIC for any taxable year during which the U.S. investor holds common shares.

Dividends distributed by the Company on the Shares to certain related parties in low-tax jurisdictions might in the future become subject to an alternative Dutch withholding tax on dividends.

Under current Dutch tax law, dividends paid on the Shares are in principle subject to Dutch dividend withholding tax at a rate of 15% under the Dutch Dividend Withholding Tax Act (“Regular dividend withholding tax”), unless a domestic or treaty exemption or reduction applies. On 25 March 2021, the Dutch State Secretary for Finance submitted a proposal of law to the Dutch parliament pursuant to which an alternative withholding tax (“Alternative withholding tax”) will be imposed on dividends paid to related entities in low-tax jurisdictions, effective 1 January 2024. An entity is related if (i) it holds, directly or indirectly a qualifying interest in the Company, (ii) the Company directly or indirectly holds a qualifying interest in the entity or (iii) it is an entity in which a third party holds a direct or indirect qualifying interest while that third party also holds a qualifying interest in the Company. An entity is also considered related to the Company if the entity is part of a collaborating group (samenwerkende groep) of entities that jointly directly or indirectly holds a qualifying interest in the Company. The term qualifying interest means a direct or indirectly held interest—either by an entity individually or jointly if an entity is part of a collaborating group—that enables such entity or such collaborating group to exercise a definite influence over another entities’ decisions, such as the Company, and allows it to determine the other entities’ activities. The Alternative withholding tax will be imposed at the highest Dutch corporate income tax rate in effect at the time of the distribution (currently 25%). The Alternative withholding tax will be reduced, but not below zero, with any Regular dividend withholding tax imposed on distributions. As such, based on currently applicable rates, the overall effective rate of withholding of Regular dividend withholding tax and Alternative withholding tax will not exceed the highest corporate income tax rate in effect at the time of the distribution (currently 25%). The proposal of law is subject to amendment during the course of the legislative process and it needs to be approved by both chambers of the Dutch parliament before it can enter into force.

USE OF PROCEEDS

We may issue and sell our common shares from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.

As of September 30, 2021, we had cash and cash equivalents of €198.7 million. We anticipate that we will use our existing liquidity and the net proceeds of this offering primarily to fund research and development expenses for our clinical and preclinical research and development activities and for working capital and general corporate purposes.

Our expected use of net proceeds from this offering represents our current intentions based upon our present plans and business condition. As of the date of this prospectus supplement, we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the closing of this offering or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual use of net proceeds will vary depending on numerous factors, including our ability to obtain additional financing, the relative success and cost of our research, preclinical and clinical development programs, including a change in our planned course of development or the termination of a clinical program necessitated by the results of data received from clinical trials, the amount and timing of additional revenues, if any, received from our collaborations and whether we enter into future collaborations. As a result, management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds of this offering. In addition, we might decide to postpone or not pursue other clinical trials or preclinical activities if the net proceeds from this offering and our other sources of cash are less than expected.

Based on our current operating and budget assumptions, we believe that our existing liquidity will enable us to fund our operating expenses and capital expenditure requirements at least into the second half of 2023. The net proceeds of this offering, if we issue and sell our common shares with maximum aggregate sales proceeds of $100 million as specified in this prospectus supplement, would extend our financial reach, assuming that the plans for our clinical and preclinical activities remain unchanged. We have based these estimates on assumptions that may prove to be incorrect, and we could use our available capital resources sooner than we currently expect.

Pending their use, we plan to invest a portion of the net proceeds from this offering in short- and intermediate-term interest-bearing financial assets and certificates of deposit.

DIVIDEND POLICY

We have never paid or declared any cash dividends on our common shares, and we do not anticipate paying any cash dividends on our common shares in the foreseeable future. We intend to retain all available funds and any future earnings to fund the development and expansion of our business. Under Dutch law, we may only pay dividends to the extent that 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, any future determination to pay dividends will be at the discretion of our management board and requires approval of our supervisory board and will depend upon a number of factors, including our results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law and other factors our management board and supervisory board deem relevant.

DILUTION

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

Our net tangible book value as of September 30, 2021 was $153.1 million (€132.2 million), or $1.28 per common share (€1.10 per common share), based on 119,797,165 common shares then outstanding. Net tangible book value per share represents the amount of our total assets less our total liabilities, excluding intangible assets, divided by 119,797,165, the total number of our common shares issued and outstanding at September 30, 2021.

After giving effect to the assumed sale by us of our common shares in the aggregate amount of $100 million at an assumed public offering price of $6.23 per share (the last sale price of our common shares on November 9, 2021 as reported on Nasdaq), less the estimated commissions and estimated offering expenses payable by us, our net tangible book value at September 30, 2021 would have been $250.5 million, or $1.84 per common share. This represents an immediate increase in net tangible book value of $0.56 per share to existing shareholders and an immediate dilution of $4.39 per share to investors in this offering. The following table illustrates this per share dilution. The as adjusted information is illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time our common shares are sold pursuant to this prospectus supplement. The shares sold in this offering, if any, will be sold from time to time at various prices.

The above discussion and table are based on our actual common shares outstanding as of September 30, 2021 and excludes:

To the extent that outstanding options are exercised, you will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of such securities may result in further dilution to our shareholders.

DUTCH TAX CONSIDERATIONS

This section outlines the principal Dutch tax consequences of the acquisition, holding, settlement, redemption and disposal of common shares in the capital of the Company, or the Shares. It does not present a comprehensive or complete description of all aspects of Dutch tax law which could be relevant to a holder of Shares (a “Shareholder”). For Dutch tax purposes, a Shareholder may include an individual or entity not holding the legal title to the Shares, but to whom, or to which, the Shares are, or the income from the Shares is, nevertheless attributed based either on this individual or entity owning a beneficial interest in the Shares or on specific statutory provisions. These include statutory provisions attributing Shares to an individual who is, or who has directly or indirectly inherited from a person who was, the settlor, grantor or similar originator of a trust, foundation or similar entity that holds the Shares.

This section is intended as general information only. A prospective Shareholder should consult his own tax adviser regarding the tax consequences of any acquisition, holding or disposal of Shares.

This section is based on Dutch tax law as applied and interpreted by Dutch tax courts and as published and in effect on the date of this prospectus supplement, including the tax rates applicable on that date, without prejudice to any amendments introduced at a later date and implemented with or without retroactive effect.

Any reference in this section made to Dutch taxes, Dutch tax or Dutch tax law should be construed as a reference to any taxes of any nature levied by or on behalf of the Netherlands or any of its subdivisions or taxing authorities or to the law governing such taxes, respectively. The Netherlands means the part of the Kingdom of the Netherlands located in Europe.

Any reference made to a treaty for the avoidance of double taxation concluded by the Netherlands includes the Tax Regulation for the Kingdom of the Netherlands (Belastingregeling voor het Koninkrijk), the Tax Regulation for the State of the Netherlands (Belastingregeling voor het land Nederland), the Tax Regulations for the Netherlands and Curacao (Belastingregeling Nederland Curacao), the Tax Regulations for the Netherlands and St. Maarten (Belastingregeling Nederland Sint Maarten) and the Agreement between the Taipei Representative Office in the Netherlands and the Netherlands Trade and Investment Office in Taipei for the avoidance of double taxation.

This section does not describe any Dutch tax considerations or consequences that may be relevant where a Shareholder:

S-10

Withholding Tax

A Shareholder is generally subject to Dutch dividend withholding tax at a rate of 15% on dividends distributed by the Company. Generally, the Company is responsible for the withholding of such dividend withholding tax at source.

However, a Shareholder will generally not be subject to Dutch dividend withholding tax on dividends distributed by the Company if, and for as long as, the Company is resident solely in Germany for purposes of the convention between Germany and the Netherlands for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income (the “German—Dutch tax treaty”), unless:

Dividends distributed by the Company include, but are not limited to:

If a Shareholder is resident or deemed to be resident in the Netherlands, such Shareholder is generally entitled to an exemption or a credit for any Dutch dividend withholding tax against his Dutch tax liability and to a refund of any residual Dutch dividend withholding tax.

Depending on specific circumstances, a Shareholder resident in a country other than the Netherlands may be entitled to an exemption from, reduction of, or full or partial refund of, Dutch dividend withholding tax under Dutch law, European Union, or the EU, law or treaties for the avoidance of double taxation.

S-11

According to Dutch domestic anti-dividend stripping rules, no credit against Dutch tax, exemption from, reduction, or refund of Dutch dividend withholding tax will be granted if the recipient of the dividends paid by the Company is not considered to be the beneficial owner (uiteindelijk gerechtigde) of those dividends.

The Dutch Dividend Withholding Tax Act 1965 (Wet op de dividendbelasting 1965) (“DWTA”), provides for a non-exhaustive negative description of a beneficial owner. According to the DWTA, a Shareholder will not be considered the beneficial owner of the dividends for this purpose if as a consequence of a combination of transactions:

Please refer to the paragraph “Risk Factors” in our most recent Annual Report on Form 20-F, which is incorporated herein by reference, for a risk factor regarding the Company’s tax residency and the consequences thereof. Please refer to the paragraph “Risk Factors” in this prospectus supplement for a risk regarding proposed legislation relating to dividends distributed by a Dutch company to certain related parties in low-taxed jurisdictions which may be subject to an additional Dutch dividend withholding tax.

Taxes on Income and Capital Gains

Residents of the Netherlands

The description of certain Dutch tax consequences in this subsection is only intended for the following Shareholders:

Dutch Individuals engaged or deemed to be engaged in an enterprise or in miscellaneous activities

Dutch Individuals engaged or deemed to be engaged in an enterprise or in miscellaneous activities (resultaat uit overige werkzaamheden) are generally subject to income tax at statutory progressive rates with a maximum of 49.50% (2021) on any benefits derived or deemed to be derived from the Shares, including any capital gains realized on any disposal of the Shares, where those benefits are attributable to:

Dutch Individuals not engaged or deemed to be engaged in an enterprise or in miscellaneous activities

Generally, the Shares held by a Dutch Individual who is not engaged or deemed to be engaged in an enterprise or in miscellaneous activities, or who is so engaged or deemed to be engaged but the Shares are not attributable to that enterprise or miscellaneous activities, will be subject to annual income tax imposed on a fictitious yield on the Shares. The Shares held by this Dutch Individual will be taxed under the regime for savings and investments (inkomen uit sparen en beleggen). Irrespective of the actual income or capital gains realized, the

S-12

annual taxable benefit from a Dutch Individual’s assets and liabilities taxed under this regime, including the Shares, is set at a percentage of the positive balance of the fair market value of these assets, including the Shares, and the fair market value of these liabilities. The percentage (2021) increases:

The percentages under (i) to (iii) will be reassessed each year and the amounts under (i) to (iii) will be adjusted for inflation each year. No taxation occurs if this positive balance does not exceed a certain threshold (heffingvrij vermogen). The fair market value of assets, including the Shares, and liabilities that are taxed under this regime is measured exclusively on 1 January of every calendar year. The tax rate under the regime for savings and investments is a flat rate of 31%.

Dutch Corporate Entities

Dutch Corporate Entities are generally subject to corporate income tax at statutory rates up to 25% (2021) on any benefits derived or deemed to be derived from the Shares, including any capital gains realized on their disposal.

Non-Residents of the Netherlands

The description of certain Dutch tax consequences in this subsection is only intended for the following Shareholders:

Non-Dutch Individuals

A Non-Dutch Individual will not be subject to any Dutch taxes on income or capital gains derived from the purchase, ownership and disposal or transfer of the Shares, other than withholding tax as described above, unless:

S-13

Non-Dutch Corporate Entities

A Non-Dutch Corporate Entity will not be subject to any Dutch taxes on income or capital gains in respect of the purchase, ownership and disposal or transfer of the Shares, other than withholding tax as described above, unless:

Under certain specific circumstances, Dutch taxation rights may be restricted for Non-Dutch Individuals and Non-Dutch Corporate Entities pursuant to treaties for the avoidance of double taxation concluded by the Netherlands.

Dutch Gift Tax or Inheritance Tax

No Dutch gift tax or inheritance tax is due in respect of any gift of the Shares by, or inheritance of the Shares on the death of, a Shareholder, unless:

Other Taxes and Duties

No other Dutch taxes, including turnover or value added taxes and taxes of a documentary nature, such as capital tax, stamp or registration tax or duty, are payable by, or on behalf of, the Shareholder by reason only of the purchase, ownership and disposal of the Shares.

Residency

A Shareholder will not become a resident or deemed resident of the Netherlands by reason only of holding the Shares.

S-14

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a description of the material U.S. federal income tax consequences to the U.S. Holders described below of owning and disposing of common shares acquired in this offering. It does not describe all tax considerations that may be relevant to a particular person’s decision to acquire, own or dispose of the common shares.

This section applies only to a U.S. Holder that acquires common shares pursuant to this offering and holds such common shares as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment) for U.S. federal income tax purposes. In addition, it does not set forth all of the U.S. federal income tax consequences that may be relevant in light of the U.S. Holder’s particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Code known as the Medicare contribution tax and tax consequences applicable to U.S. Holders subject to special rules, such as:

If an entity that is classified as a partnership for U.S. federal income tax purposes holds common shares, the U.S. federal income tax treatment of a partner will depend on the status of the partner and the activities of the partner and the partnership. Partnerships holding common shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the common shares.

This section is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury Regulations, and the income tax treaty between Germany and the United States and the income tax treaty between the Netherlands and the United States (as applicable and as the context requires the “Treaty”) all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect. No assurance can be given that the Internal Revenue Service, or the IRS, will agree with the views expressed in this discussion, or that a court will not sustain any challenge by the IRS in the event of litigation. We have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the statements made and the conclusions reached in the following summary.

A “U.S. Holder” is a holder who, for U.S. federal income tax purposes, is a beneficial owner of common shares, who is eligible for the benefits of the Treaty and who is:

S-15

U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of common shares in their particular circumstances. In particular, because our group includes a U.S. subsidiary, (Affimed Inc., a Delaware corporation) and therefore under current law our non-U.S. subsidiaries (Affimed GmbH and AbCheck s.r.o.) are treated as controlled foreign corporations (regardless of whether we are or are not treated as a controlled foreign corporation), any U.S. Holder that owns or is deemed to own ten percent or more of our shares (by vote or value) is urged to consult its tax adviser regarding the potential application of the “Subpart F income” and “global intangible low-taxed income” rules to an investment in our common shares.

Taxation of Distributions

We do not currently expect to make distributions on our common shares. In the event that we do make distributions of cash or other property, subject to the passive foreign investment company rules described below, distributions paid on common shares, other than certain pro rata distributions of common shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). If we are not treated as a PFIC with respect to a U.S. Holder and were not treated as a PFIC with the respect to the U.S. Holder in the preceding taxable year, for so long as our common shares are listed on Nasdaq or another established securities market in the United States or we are eligible for benefits under the Treaty, dividends paid to such a U.S. Holder that is not a corporation would generally be eligible for taxation as “qualified dividend income” if certain other requirements are met, which is taxable at rates not in excess of the long-term capital gain rate applicable to such U.S. Holders. The amount of a dividend will include any amounts withheld by us in respect of German or Dutch income taxes.

Subject to the passive foreign investment company rules described below, the amount of the dividend will be treated as foreign-source dividend income to U.S. Holders and will not be eligible for the dividends-received deduction available to U.S. corporations under the Code. Subject to the passive foreign investment company rules described below, dividends will be included in a U.S. Holder’s income on the date of the U.S. Holder’s receipt of the dividend. The amount of any dividend income paid in euros will be the U.S. dollar amount calculated by reference to the exchange rate in effect on the date of actual or constructive receipt, regardless of whether the payment is in fact converted into U.S. dollars at that time. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

Subject to applicable limitations, German or Dutch income taxes withheld from dividends on common shares at a rate not exceeding the rate provided by the Treaty will be eligible for credit against the U.S. Holder’s U.S. federal income tax liability. German or Dutch taxes withheld in excess of the rate applicable with respect to such U.S. Holder under the Treaty will not be eligible for credit against a U.S. Holder’s federal income tax liability.

The rules governing foreign tax credits are complex and U.S. Holders should consult their tax advisers regarding the creditability of foreign taxes in their particular circumstances. In lieu of claiming a foreign tax credit, U.S. Holders may deduct foreign taxes, including any German or Dutch withholding tax, in computing their taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all foreign taxes paid or accrued in the taxable year.

Sale or Other Disposition of Common Shares

Subject to the passive foreign investment company rules described below, gain or loss realized on the sale or other disposition of common shares will be capital gain or loss, and will be long-term capital gain or loss if the

S-16

U.S. Holder held the common shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in the common shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes.

Passive Foreign Investment Company Rules

Under the Code, we will be a PFIC for any taxable year in which, after the application of certain “look-through” rules with respect to subsidiaries, either (i) 75% or more of our gross income consists of “passive income,” or (ii) 50% or more of the average quarterly value of our assets consists of assets that produce, or are held for the production of, “passive income.” Although we have not performed a definitive PFIC analysis using U.S. federal income tax principles, based on certain estimates as to composition of our income and assets, including the implied value, based on our market capitalization of our assets that produce non-passive income, in 2021 to date, it is possible that we would be treated as a PFIC with respect to 2021. Passive income generally includes, among other things, interest, dividends, certain non-active rents and royalties, and capital gains. Whether we will be a PFIC in 2021 or any future taxable year is uncertain because, among other things, we currently own a substantial amount of passive assets, including cash, and because the valuation of our assets that generate non-passive income for PFIC purposes, including our intangible assets, is uncertain and may vary substantially over time. In addition, the composition of our assets and income may vary substantially over time. The average quarterly value of our assets for purposes of determining our PFIC status for any taxable year will generally be determined in part by reference to our market capitalization, which has fluctuated and may continue to fluctuate significantly over time. Accordingly, there can be no assurance that we will not be a PFIC in 2021 or for any future taxable year.

The IRS recently finalized Treasury Regulations that address various issues related to determining whether a foreign corporation is a PFIC and whether a U.S. shareholder holds PFIC stock and recently released proposed Treasury Regulations that address various issues related to determining whether a foreign corporation is a PFIC. These Treasury Regulations and proposed Treasury Regulations (if finalized) may affect whether we are a PFIC in 2021 or in any future year. You should consult your tax adviser regarding the effect, if any, these Treasury Regulations may have, or such proposed Treasury Regulations would have, on the determination of our PFIC status.

In addition, we may, directly or indirectly, hold equity interests in Lower-tier PFICs. Under attribution rules, if we are a PFIC, U.S. Holders will be deemed to own their proportionate shares of Lower-tier PFICs and will be subject to U.S. federal income tax according to the rules described in the following paragraphs on (i) certain distributions by a Lower-tier PFIC and (ii) a disposition of shares of a Lower-tier PFIC, in each case as if the U.S. Holders held such shares directly, even though the U.S. Holders have not received the proceeds of those distributions or dispositions directly.

For so long as we are treated as a PFIC with respect to a U.S. Holder (or were treated as a PFIC with respect to the U.S. Holder in the preceding taxable year), dividends paid to certain non-corporate U.S. Holders will not be eligible for taxation as “qualified dividend income.” In addition, if we were a PFIC for any taxable year during which a U.S. Holder held common shares (assuming such U.S. Holder has not made a timely mark-to-market election, as described below), gain recognized by a U.S. Holder on a sale or other disposition (including certain pledges) of the common shares, or an indirect disposition of shares of a Lower-tier PFIC, would be allocated ratably over the U.S. Holder’s holding period for the common shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the amount allocated to that taxable year. Further, to the extent that any distribution received by a U.S. Holder on its common shares (or a distribution by a Lower-tier PFIC to its shareholder that is deemed to be received by a U.S. Holder) exceeds 125% of the average of the annual distributions on the common shares received during the

S-17

preceding three years or the U.S. Holder’s holding period, whichever is shorter, that distribution would be subject to taxation in the same manner as gain, described immediately above.

If we are a PFIC for any year during which a U.S. Holder holds common shares, we generally would continue to be treated as a PFIC with respect to that U.S. Holder for all succeeding years during which the U.S. Holder holds common shares, even if we ceased to meet the threshold requirements for PFIC status.

A U.S. Holder can avoid certain of the adverse rules described above by making a mark-to-market election with respect to its common shares, provided that the common shares are “marketable.” Common shares will be marketable if they are “regularly traded” on a “qualified exchange” or other market within the meaning of applicable Treasury Regulations. Our common shares will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the common shares is traded on a qualified exchange on at least 15 days during each calendar quarter. Nasdaq, on which the common shares are currently listed, is a qualified exchange for this purpose. If a U.S. Holder makes the mark-to-market election, it will recognize as ordinary income any excess of the fair market value of the common shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the common shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. Holder makes the election, the U.S. Holder’s tax basis in the common shares will be adjusted to reflect the income or loss amounts recognized. Any gain recognized on the sale or other disposition of common shares in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). U.S. Holders should consult their tax advisers regarding the availability and advisability of making a mark-to-market election with respect to their common shares because we may have Lower-tier PFICs for which a mark-to-market election may not be available.

In addition, in order to avoid the application of the foregoing rules, a U.S. Holder can make qualified electing fund elections (any such election, a “QEF Election”) with respect to us and each Lower-tier PFIC in the first taxable year that we and each Lower-tier PFIC are treated as PFICs with respect to the U.S. Holder. A U.S. Holder must make the QEF Election for each PFIC by attaching a separate properly completed IRS Form 8621 for each PFIC to the U.S. Holder’s timely filed U.S. federal income tax return generally for the first taxable year that the entity is treated as a PFIC with respect to the U.S. Holder. A U.S. Holder generally may make a separate election to defer payment of taxes on the undistributed income inclusion under the QEF rules, but if deferred, any such taxes are subject to an interest charge. We currently intend to provide the information necessary for a U.S. investor to make a QEF Election with respect to us and each Lower-tier PFIC that we control for 2021 and for any future years with respect to which we determine that we or any Lower-tier PFIC that we control are or are likely to be a PFIC. If a U.S. Holder makes a QEF Election with respect to us or a Lower-tier PFIC that we control, the U.S. Holder will be currently taxable on its pro rata share of the PFIC’s ordinary earnings and net capital gain (at ordinary income and capital gain rates, respectively) for each taxable year that the entity is classified as a PFIC and will not be required to include such amounts in income when actually distributed by the PFIC. If a U.S. Holder makes a QEF Election with respect to us, any distributions paid by us out of our earnings and profits that were previously included in the U.S. Holder’s income under the QEF Election will not be taxable to the U.S. Holder.

A U.S. Holder will increase its tax basis in its common shares by an amount equal to any income included under the QEF Election and will decrease its tax basis by any amount distributed, if any, on the common shares that is not included in its income. In addition, a U.S. Holder will recognize capital gain or loss on the disposition of common shares in an amount equal to the difference between the amount realized and its adjusted tax basis in the common shares. U.S. Holders should note that if they make QEF Elections with respect to us and Lower-tier PFICs, if any, they may be required to pay U.S. federal income tax with respect to their common shares for any taxable year significantly in excess of any cash distributions, if any, received on the shares for such taxable year. U.S. Holders should consult their tax advisers regarding making QEF Elections in their particular circumstances.

S-18

In addition, if we were a PFIC or, with respect to a particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

If a U.S. Holder owns common shares during any year in which we are a PFIC, the U.S. Holder must file annual reports containing such information as the U.S. Treasury may require on IRS Form 8621 (or any successor form) with respect to us (regardless of whether a mark-to-market election or QEF Election is made), generally with the U.S. Holder’s federal income tax return for that year, unless otherwise specified in the instructions with respect to such form. U.S. Holders should consult their tax advisers regarding whether we are or were a PFIC and the potential application of the PFIC rules.

Information Reporting with Respect to Foreign Financial Assets

Certain U.S. Holders who are individuals and certain entities may be required to report information relating to an interest in our common shares, subject to certain exceptions (including an exception for common shares held in accounts maintained by certain U.S. financial institutions), U.S. Holders should consult their tax advisers regarding whether or not they are obligated to report information relating to their ownership and disposition of the common shares.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS.

S-19

PLAN OF DISTRIBUTION

We have entered into a sale agreement with Jefferies, under which we may offer and sell up to $100,000,000 of our common shares from time to time through Jefferies acting as agent. Sales of our common shares, if any, under this prospectus supplement and the accompanying prospectus will be made by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act.

Each time we wish to issue and sell our common shares under the sale agreement, we will notify Jefferies of the number of shares to be issued, the dates on which such sales are anticipated to be made, any limitation on the number of shares to be sold in any one day and any minimum price below which sales may not be made. Once we have so instructed Jefferies, unless Jefferies declines to accept the terms of such notice, Jefferies has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up to the amount specified on such terms. The obligations of Jefferies under the sale agreement to sell our common shares are subject to a number of conditions that we must meet.

The settlement of sales of shares between us and Jefferies is generally anticipated to occur on the second trading day following the date on which the sale was made. Sales of our common shares as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Jefferies may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay Jefferies a commission of up to 3.00% of the aggregate gross proceeds we receive from each sale of our common shares. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We will report at least quarterly the number of common shares sold through Jefferies under the sale agreement, the net proceeds to us and the compensation paid by us to Jefferies in connection with the sales of common shares. In addition, we have agreed to reimburse Jefferies for the fees and disbursements of its counsel, payable upon execution of the sale agreement, in an amount not to exceed $50,000, in addition to certain ongoing disbursements of its legal counsel. The remaining sale proceeds, after deducting any other transaction fees, will equal our net proceeds from the sale of such shares.

Jefferies will provide written confirmation to us before the open on Nasdaq on the day following each day on which our common shares are sold under the sale agreement. Each confirmation will include the number of shares sold on that day, the aggregate gross proceeds of such sales and the proceeds to us.

In connection with the sale of our common shares on our behalf, Jefferies will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of Jefferies will be deemed to be underwriting commissions or discounts. We have agreed to indemnify Jefferies against certain civil liabilities, including liabilities under the Securities Act. We have also agreed to contribute to payments Jefferies may be required to make in respect of such liabilities.

The offering of our common shares pursuant to the sale agreement will terminate upon the earlier of (i) the sale of all common shares subject to the sale agreement and (ii) the termination of the sale agreement as permitted therein. We and Jefferies may each terminate the sale agreement at any time upon ten days’ prior notice.

This summary of the material provisions of the sale agreement does not purport to be a complete statement of its terms and conditions. A copy of the sale agreement is filed as an exhibit to a report on Form 6-K filed under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and incorporated by reference in this prospectus supplement.

Re: Post-Effective Amendment to Registration Statement on Form F-3

Ladies and Gentlemen:

We are issuing this opinion letter in our capacity as special U.S. counsel to Affimed N.V., a Dutch public company with limited liability (naamloze vennootschap) (the “Company”), in connection with a Post-Effective Amendment (the “Amendment”) to the Registration Statement on Form F-3 (File No. 333-260946) (as amended or supplemented, the “Amended Registration Statement”) filed with Securities and Exchange Commission (the “Commission”) by the Company, to register the offer and sale, from time to time, by the Company of up to $250,000,000 of (i) common shares, nominal value €0.01 per share (the “Common Shares”), of the Company; (ii) senior debt securities (the “Senior Debt Securities”), which may be issued pursuant to an indenture (the “Senior Indenture”) to be executed by the Company and the trustee to be named therein; and subordinated debt securities (the “Subordinated Debt Securities” and, together with the Senior Debt Securities, the “Debt Securities”), which may be issued pursuant to an indenture (the “Subordinated Indenture” and, together with the Senior Indenture, the “Indentures”) to be executed by the Company and the trustee to be named therein; (iii) warrants or other rights to purchase or otherwise acquire Common Shares or Debt Securities of the Company (the “Warrants”); (iv) purchase contracts (the “Purchase Contracts”) for the purchase or sale of the Company’s securities or securities of third parties, a basket of such securities, an index or indices of such securities or any combination of the above; and (v) units (the “Units”) consisting of one or more Common Shares, Debt Securities, Warrants, Purchase Contracts, or any combination of such securities.

For purposes of the opinions hereinafter expressed, we have examined the Amendment, the Amended Registration Statement, copies of the forms of the Indentures and originals or copies, certified and otherwise identified to our satisfaction, of such other documents, corporate or limited liability company records, certificates of public officials and other instruments as we have deemed necessary as a basis for the opinions expressed herein. Insofar as the opinions expressed herein involve factual matters, we have relied (without independent factual investigation), to the extent we deemed proper or necessary, upon certificates of, and other communications with, officers and employees of the Company and upon certificates of public officials.

In connection with this opinion, we have assumed that (i) the Amended Registration Statement will have become effective under the Securities Act of 1933, as amended (the “Act”); (ii) a prospectus supplement will have been prepared and filed with the Commission describing the securities offered thereby; (iii) all offered securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Amended Registration Statement and the applicable prospectus supplement; (iv) a definitive purchase, underwriting, sales agency or similar agreement with respect to the offered securities will have been duly authorized and validly executed and delivered by the Company and the other parties thereto; (v) any applicable indenture and indenture trustee will have been qualified under the Trust Indenture Act of 1939, as amended; and (vi) with respect to any Units, consisting of one or more Common Shares, Debt Securities, Warrants, Purchase Contracts, or any combination of such securities, such Units will be authorized, validly issued, fully paid and nonassessable (to the extent applicable).

Based on the foregoing, and having regard for such legal considerations as we have deemed relevant, we advise you that:

Affimed N.V.

Each opinion (an “enforceability opinion”) in this letter that any security is a valid and binding obligation or is enforceable in accordance with its terms is subject to: (i) the effect of bankruptcy, insolvency, fraudulent conveyance and other similar laws and judicially developed doctrines in this area such as substantive consolidation and equitable subordination; (ii) the effect of general principles of equity; and (iii) other commonly recognized statutory and judicial constraints on enforceability including statutes of limitations. In addition, we do not express any opinion as to the enforceability of any rights to contribution or indemnification which may be violative of public policy underlying any law, rule or regulation (including any federal or state securities law, rule or regulation). “General principles of equity” include, but are not limited to: principles limiting the availability of specific performance and injunctive relief; principles which limit the availability of a remedy under certain circumstances where another remedy has been elected; principles requiring reasonableness, good faith and fair dealing in the performance and enforcement of an agreement by the party seeking enforcement; principles which may permit a party to cure a material failure to perform its obligations; and principles affording equitable defenses such as waiver, laches and estoppel. We express no opinion with respect to the enforceability of any provision which purports to waive the benefit of usury laws. It is possible that terms in a particular contract covered by our enforceability opinion may not prove enforceable for reasons other than those explicitly cited in this letter should an actual enforcement action be brought, but (subject to all the exceptions, qualifications, exclusions and other limitations contained in this letter) such unenforceability would not in our opinion prevent the party entitled to enforce that contract from realizing the principal benefits purported to be provided to that party by the terms in that contract which are covered by our enforceability opinion.

This opinion does not cover the law of any jurisdiction other than the law of the State of New York. We did not find it necessary for the purposes of this opinion, and accordingly we do not purport to cover herein, the application of the securities or “Blue Sky” laws of the various states. We undertake no responsibility to update or supplement this opinion in response to changes in law or future events or other circumstances. We have assumed the indentures, purchase contract agreement, warrant agreement and unit agreement referenced in the numbered paragraphs above will be governed by the law of the State of New York.

This opinion is furnished to you in connection with the filing of the Amendment and is not to be used, circulated, quoted or otherwise relied upon or otherwise referred to by any other person for any other purpose.

The Securities may be issued from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect. This opinion speaks only as of the date hereof and we assume no obligation to revise or supplement this opinion.

We hereby consent to the filing of this opinion as an exhibit to the Amendment and to the reference to our firm under the heading “Legal Matters” in the Amendment.
