Please note that while our proxy materials are available at the website referenced in the Notice of Internet Availability, and our Notice of Annual Meeting, proxy statement and Annual Report on Form 10-K are available on our website, no other information contained on either website is incorporated by reference in or considered to be a part of this document.

Who is soliciting my proxy?
Proxies are solicited by and on behalf of our Board of Directors. The individuals named in the proxy have been designated as proxy holders by our Board of Directors. When you return a proxy that is properly dated and executed, your shares represented by the proxy will be voted at the Annual Meeting in accordance with your instructions. If you do not give specific instructions on your proxy card, your shares will be voted in accordance with the recommendations of our Board of Directors. If any matters not described in this proxy statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the Annual Meeting is postponed or adjourned, the proxy holders can vote your shares on the new meeting date, unless you have properly revoked your proxy, as described above.
Who pays the cost for soliciting proxies?
The Company will pay the cost for the solicitation of proxies by the Board of Directors. The solicitation of proxies will be made primarily by mail and through internet access to materials. Proxies may also be solicited personally, by telephone, fax or e-mail by employees of the Company without any remuneration to such individuals other than their regular compensation. The Company will also reimburse brokers, banks, custodians, other nominees, and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.
Will my shares be voted if I do not return my proxy?
If your shares are registered directly in your name, your shares will not be voted if you do not vote over the Internet, by telephone, by returning your proxy or by ballot at the Annual Meeting. If your shares are held in street name, your bank, broker or other nominee may under certain circumstances vote your shares if you do not timely return your proxy. Banks,Under the rules of the New York Stock Exchange (“NYSE”), banks, brokers and other nominees can vote customers’ unvoted shares on routine“routine” matters, but cannot vote such shares on non-routine“non-routine” matters. If you do not timely return a proxy to your bank, broker or other nominee to vote your shares, your bank, broker or other nominee may, on routine matters, either vote your shares or leave your shares unvoted. Your bank, broker or other nominee cannot vote your shares on any non-routine matter. The election of directors (Proposal 1) is a non-routine matter. The ratification of the appointment of our independent registered public accounting firm (Proposal 2) is a, the increase in our authorized shares (Proposal 3) and the reverse stock split (Proposal 4) are routine matter.matters. We encourage you to provide voting instructions to your bank, broker or other nominee by giving your proxy to them. This ensures that your shares will be voted at the Annual Meeting according to your instructions. You should receive directions from your bank, broker or other nominee about how to submit your proxy to them at the time you receive this proxy statement.
Can I change my vote?
You may revoke your proxy at any time before it is voted by notifying the Corporate Secretary in writing, by returning a signed proxy with a later date, by transmitting a subsequent vote over the Internet or by telephone prior to the close of the Internet voting facility or the telephone voting facility. You may also attend the virtual meeting and vote during the meeting. If your stock is held in street name, you must contact your broker or nominee for instructions as to how to change your vote.
How is a quorum reached?
The presence, by virtual attendance or by proxy, of holders of at least a majority of the total number of outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares held of record by stockholders or brokers, bankers or other nominees who do not return a signed and dated proxy or attend the Annual Meeting virtually will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Abstentions, withhold votes and broker non-votes, if any, will be counted for purposes of determining whether a quorum is present for the transaction of business at the meeting.

​

What are broker non-votes?
When a beneficial owner of shares held in street name does not give voting instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be non-routine, the broker, bank or other such agent cannot vote the shares. When there is at least one routine matter that the broker, bank or other securities intermediary votes on, the shares that are un-voted on non-routine matters are counted as broker non-votes. The election of directors (Proposal 1) is a non-routine matter, and we therefore expect broker non-votes to exist in connection with that proposal. The ratification of the appointment of our independent registered public accounting firm (Proposal 2), the increase in our authorized shares (Proposal 3) and the reverse stock split (Proposal 4) are routine matters, and we therefore do not expect broker non-votes to exist in connection with those proposals.
What vote is required to approve each item and how are votes counted?
Votes cast by proxy or online at the Annual Meeting will be counted by the persons appointed by the Company to act as tabulators for the meeting. The tabulators will count all votes FOR, andWITHHELD, AGAINST,

3
​

abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Abstentions, votes withheld and broker non-votes are not counted as votes cast and, therefore, do not have the effect of votes in opposition to such proposals. A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.
•
Proposal 1 — Director Elections
​
The threetwo nominees for director to receive the highest number of votes FOR election will be elected as directors. This is called a plurality. Proposal 1 is a non-routine matter. Therefore, if your shares are held by your brokerage firm in street name and you do not timely provide voting instructions with respect to your shares, your brokerage firm cannot vote your shares on Proposal 1. Shares held in street name by banks, brokerage firms or other nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 1 will not be counted as votes FOR or WITHHELD from any nominee. As a result, such “broker non-votes”broker non-votes will have no effect on the voting on Proposal 1. You may:
•
vote FOR all nominees;
​
•
vote FOR one or more nominees and WITHHOLD your vote from the other nominees; or
​
•
WITHHOLD your vote from all nominees.
​
Votes that are withheld will not be included in the vote tally for the election of directors and will not affect the results of the vote.
•
Proposal 2 — Auditor Ratification
​
To approve Proposal 2, holders of a majority of the votes properly cast on the matter must vote FOR the proposal. For the ratification of the selection of PwC Wirtschaftsprüfung GmbH as our independent registered public accounting firm for the fiscal year ending December 31, 2023,2024, the votes cast FOR must exceed the votes cast AGAINST. Only FOR and AGAINST votes will affect the outcome. Abstentions will be counted for purposes of establishing a quorum and, if a quorum is present, will have no effect on the voting of Proposal 2. Proposal 2 is a routine matter. Therefore, if your shares are held by your bank, broker or other nominee in street name andbut you do not vote your shares on this proposal, your bank, broker or other nominee may vote your shares on Proposal 2. We do not expect there to be any broker non-votes on this proposal.
Proposal 3 — Authorized Stock Increase Proposal
To approve Proposal 3, holders of a majority of the outstanding shares of common stock of the Company entitled to vote on the matter must vote FOR the proposal. For amending the Company’s Amended and Restated Certificate of Incorporation to increase the total number of authorized shares of common stock from 200,000,000 shares to 400,000,000 shares, abstentions and broker non-votes will be counted for purposes of establishing a quorum and, if a quorum is present, will have the same practical effect as a vote against Proposal 3. We have been advised by the NYSE that Proposal 3 is a routine matter. Therefore, if your shares are held by your bank, broker or other nominee in street name but you do not vote your

4
​

shares on this proposal, your bank, broker or other nominee may vote your shares on Proposal 3. We do not expect there to be any broker non-votes on this proposal.
Proposal 4 — Reverse Split Proposal
To approve Proposal 4, holders of a majority of the outstanding shares of common stock of the Company entitled to vote on the matter must vote FOR the proposal. For amending the Company’s Amended and Restated Certificate of Incorporation to effect a reverse stock split of Company common stock (with a proportionate reduction in the authorized number of shares of Company common stock), in the range of 1-for-2 to 1-for-10 at any time prior to June 17, 2025, if and as determined by the Company’s board of directors, abstentions and broker non-votes will be counted for purposes of establishing a quorum and, if a quorum is present, will have the same practical effect as a vote against Proposal 4. We have been advised by the NYSE that Proposal 4 is a routine matter. Therefore, if your shares are held by your bank, broker or other nominee in street name but you do not vote your shares on this proposal, your bank, broker or other nominee may vote your shares on Proposal 4. We do not expect there to be any broker non-votes on this proposal.
If there are insufficient votes to approve Proposals 1, 2, 3 or 2,4, your proxy may be voted by the persons named in the proxy to adjourn the Annual Meeting in order to solicit additional proxies in favor of the approval of such proposal. If the Annual Meeting is adjourned or postponed for any purpose, at any subsequent reconvening of the meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Annual Meeting unless you withdraw or revoke your proxy. Your proxy may be voted in this manner even though it may have been voted on the same or any other matter at a previous session of the Annual Meeting.
Could other matters be decided at the Annual Meeting?
The Company does not know of any other matters that may be presented for action at the Annual Meeting. Should any other business come before the meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in accordance with their best judgment. If you hold shares through a broker, bank or other nominee as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matter.
What happens if the Annual Meeting is postponed or adjourned?
Your proxy may be voted at the postponed or adjourned meeting. You will still be able to change your proxy until it is voted.
How can I find out the results of the voting at the Annual Meeting?
Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K (“Form 8-K”8-K”), that we expect to file with the SEC within four

4
​

business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.
What does it mean if I receive more than one proxy card or voting instruction form?
It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.
Implications of being an “emerging growth company” and a “smaller reporting company”.
We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”“JOBS Act”). For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to public companies that are not

5
​

emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding nonbinding advisory votes on executive compensation and stockholder approval of any golden parachute payments not previously approved. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering in April 2019, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which requires the market value of our common stock that is held by non-affiliates to exceed $700.0 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the previous rolling three-year period.
We are also a “smaller reporting company,” meaning that the market value of our stock held by non- affiliatesnon-affiliates is less than $700 million and our annual revenue was less than $100 million during our most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure and other requirements that are applicable to other public companies that are not smaller reporting companies.
Who should I call if I have any additional questions?
If you hold your shares directly, please call Reinhard Kandera, Chief Financial OfficerNicolas Reischer, Corporate Secretary of the Company, at +43 1 890 63 60. If your shares are held in street name, please contact the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

Pursuant to the By-laws,our amended and restated bylaws, the Board of Directors has fixed the number of directors at nineeight as of the date of this year’s Annual Meeting of Stockholders.
Vacancies on the Board of Directors are filled exclusively by the affirmative vote of a majority of the remaining directors, even if less than a quorum is present, and not by the stockholders. Your proxy cannot be voted for a greater number of persons than the number of director nominees named in this proxy statement.
Information relating to each director nominee and each continuing director, including his or her period of service as a director of the Company, principal occupation and other biographical material is shown below.

​
•
Class II, whose term will expire at the Annual Meeting of Stockholders to be held in 2024; and

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors.

Generally, our Nominating and Corporate Governance Committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors,advisers, through the recommendations submitted by stockholders or through such other methods as the Nominating and Corporate Governance Committee deems to be helpful to identify candidates.

The Nominating and Corporate Governance Committee may gather information about the candidates through interviews, detailed questionnaires, background checks or any other means that the Nominating and Corporate Governance Committee deems to be appropriate in the evaluation process. The Nominating and Corporate Governance Committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our Board of Directors. Based on the results of the evaluation process, the Nominating and Corporate Governance Committee recommends candidates for the Board of Directors’ approval as director nominees for election to the Board of Directors.

Leadership Structure and Risk Oversight
The positions of our Chairman of the Board of Directors and Chief Executive Officer are separated, with Mr. Aldag serving as our Chief Executive Officer and Dr. van de Winkel serving as the Chairman. Separating these positions allows Mr. Aldag, as our Chief Executive Officer, to focus on our day-to-day business, while allowing the Chairman to lead the boardBoard of directorsDirectors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors recognizes the time, effort and energy that Mr. Aldag, as our Chief Executive Officer, must devote to his position in the current business environment, as well as the commitment required to serve as our Chairman, particularly as the Board of Directors’ oversight responsibilities continue to grow. Our Board of Directors also believes that this structure ensures a greater role for the independent directors in the oversight of our company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our Board of Directors. Our Board of Directors believes its administration of its risk oversight function has not affected its leadership structure. Our Board of Directors believes that having separate positionsseparating the office of Chief Executive Officer and Chairman of the Board of Directors is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance. Our corporate governance guidelines provide the flexibility for our Board of Directors to modify our leadership structure in the future, as it deems appropriate.
Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and operations, strategic direction and intellectual property, as more fully discussed under “Risk Factors” in our Annual Report on Form 10-K. Management is responsible for the day-to-day management of risks we face, while our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In particular, our Board of Directors is responsible for monitoring and assessing strategic risk exposure and our Audit Committee is responsible for overseeing our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including cybersecurity. The Audit Committee also monitors compliance with legal and regulatory requirements and considers and, if appropriate, approves any related-person transactions. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential

​

Our Board of Directors satisfies its risk oversight role through full reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within our company. Our Board of Directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight.
Cybersecurity and Data Privacy Oversight
Our Board of Directors addresses the Company’s cybersecurity risk management as part of its general oversight function. Our Audit Committee is responsible for the oversight of risks from cybersecurity threats and data breaches. On a quarterly basis, the Audit Committee receives an overview from our Head of IT regarding our cybersecurity threat risk management and strategy processes, which may include, for example, covering topics such as data security posture, results from third-party assessments, our incident response plan, and material cybersecurity threat risks or incidents and developments, as well as the steps management has taken to respond to such risks. The Chair of the Audit Committee periodically updates our Board of Directors on its oversight of cybersecurity and data breach risk management and strategies.

Our Digital and IT Steering Committee is responsible for approving budgets, helping prepare for cybersecurity incidents, approving cybersecurity processes, and reviewing security assessments and other security-related reports.
Our cybersecurity function, led by our Head of DevSecOps and supported by our Head of IT and third-party service providers, is responsible for our cybersecurity risk management and strategy processes. Our Head of IT, who is a Certified Information Security Manager (CISM ISACA) and a Certified Information Systems Auditor (CISA ISACA), and our Head of DevSecOps, collectively have significant prior work experience in various roles involving managing information security, developing cybersecurity strategy and implementing effective information and cybersecurity programs.

Long-Term Equity Incentives.   Our equity grant program is intended to align the interests of our named executive officers with those of our stockholders and to motivate them to make important contributions to our performance. Providing named executive officers with the opportunity to create significant wealth through stock ownership is a powerful tool to attract and retain highly-qualified executives, achieve strong long-term stock price performance, align our executives’ interests with those of our stockholders and provide a means to build real ownership in the Company. In addition, the vesting feature of our equity grants contributes to executive retention. We have historically granted equity awards to our employees, including our named executive officers, in the form of options to purchase shares of our common stock. Generally, all stock option awards vest over four years, with 25% of each option award vesting upon the first anniversary of a vesting commencement date, and the remaining shares vesting in 12 equal quarterly installments thereafter, subject to the executive officer’s continuing service relationship.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
Related Person Transactions
Other than the compensation agreements and other arrangements described under “Executive Compensation” and “Director Compensation” in this Proxy Statement and the transactions described below, since January 1, 2022 there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which the amount involved exceeded, or will exceed, $120,000 and in which any director, executive officer, holder of five percent or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.
We believe the terms obtained or consideration that we paid or received, as applicable, in connection with the transactions described below were comparable to terms available or the amounts that we would pay or receive, as applicable, in arm’s-length transactions.
Gilead Collaboration Agreement
In June 2018, we entered into a collaboration and license agreement with Gilead Sciences, Inc. (“Gilead”), a holder of greater than five percent of our capital stock, which was subsequently amended and restated in February 2022 (as amended, the “Gilead Collaboration Agreement”), whereby we and Gilead agreed to collaborate with respect to two preclinical research programs to evaluate potential vaccine products for the treatment, cure, diagnosis or prevention of HBV and HIV. Under the Gilead Collaboration Agreement, we granted Gilead an exclusive, royalty-bearing license to our technology platforms. Upon entering into the agreement in June 2018, we received a non-refundable $10.0 million upfront payment from Gilead, and upon signing the amended and restated agreement in February 2022, we received a program initiation fee of $15.0 million. Gilead is also obligated to make additional payments to us upon the achievement of pre-clinical, development and commercial milestones. The development milestones amount to $140.0 million for the HBV program, and up to $172.5 million for the HIV program, inclusive of a $10.0 million program completion fee, payable upon Gilead’s exercise of the option to pursue further development activities post Phase 1b. The commercial milestones amount to a total of $50.0 million for the HBV program, and $65.0 million for the HIV program. Additionally, Gilead is obligated to pay royalties on net sales for each program.
Gilead Stock Purchase Agreement and Registration Rights Agreement
In February 2022, we entered into a stock purchase agreement (the “Stock Purchase Agreement”) with Gilead, a holder of greater than five percent of our capital stock, that requires Gilead, at our option, to purchase up to $35.0 million of our common stock. On February 15, 2022, Gilead purchased an initial amount of 1,666,666 shares of our common stock in exchange for $5.0 million in cash at a purchase price per share equal to $3.00. On December 20, 2023, the parties amended and restated the Stock Purchase Agreement (the “Amended Stock Purchase Agreement”) and Gilead purchased 15,000,000 shares of our common stock in exchange for approximately $21.3 million in cash at a purchase price per share equal to $1.4167. Pursuant to the terms of the Amended Stock Purchase Agreement, we may require Gilead to purchase the balance of the $8.7 million of common stock as pro-rata participation in potential future equity raises. Our right to sell shares of our common stock to Gilead is subject to specified limitations, including a limitation that prevents us from requesting purchases of shares of common stock by Gilead that would result in a beneficial ownership of more than 19.9% of the total number of outstanding shares of common stock by Gilead. Pursuant to the terms of the Stock Purchase Agreement, we and Gilead agreed to enter into a registration rights agreement, which we entered into in June 2022, obligating us to file a registration statement on Form S-3 to register for resale any additional purchases of common stock within four months of any additional purchases of common stock by Gilead.

AUDIT COMMITTEE REPORT
Report of the Audit Committee of the Board of Directors
This report is submitted by the Audit Committee of the Board of Directors (the “Board”) of Hookipa Pharma Inc. (the “Company”). During 2022, the Audit Committee consisted of the three directors whose names appear below. In April 2023, Mr. Kelly resigned from the Company’s Board and its committees and Ms. Coelho was appointed as chair of the Audit Committee. None of the members of the Audit Committee is an officer or employee of the Company, and the Board has determined that each of Terry Coelho, Julie O’Neill and David Kaufman of the Audit Committee is “independent” for audit committee purposes as that term is defined under Rule 10A-3 of the Exchange Act, and the applicable rules of the Nasdaq Stock Market LLC (“Nasdaq”). Each of Terry Coelho, Julie O’Neill and David Kaufman of the Audit Committee meets the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq. The Board has designated Terry Coelho as an “audit committee financial expert,” as defined under the applicable rules of the SEC. The Audit Committee operates under a written charter adopted by the Board.
The Audit Committee’s general role is to assist the Board in monitoring our financial reporting process and related matters. Its specific responsibilities are set forth in its charter.
The Audit Committee has reviewed the Company’s financial statements for the fiscal year ended December 31, 20222023 and met with management, as well as with representatives of PwC Wirtschaftsprüfung GmbH, the Company’s independent registered public accounting firm, to discuss the consolidated financial statements.
The Audit Committee also discussed with members of PwC Wirtschaftsprüfung GmbH the matters required to be discussed by the Auditing Standard No. 1301, “Communication with Audit Committees,” as adopted by the Public Company Accounting Oversight Board.
In addition, the Audit Committee received the written disclosures and the letter from PwC Wirtschaftsprüfung GmbH required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and discussed with members of PwC Wirtschaftsprüfung GmbH its independence.
Based on these discussions, the financial statement review and other matters it deemed relevant, the Audit Committee recommended to the Board that the Company’s audited consolidated financial statements for the fiscal year ended December 31, 20222023 be included in its Annual Report on Form 10-K for the year ended 2022.2023.

PROPOSAL 2: RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The firm of PwC Wirtschaftsprüfung GmbH, independent registered public accounting firm, has been selected by the Audit Committee as auditors for the Company for the fiscal year ending December 31, 2023. PwC Wirtschaftsprüfung GmbH has served as the independent registered public accounting firm for the Company since 2017. A representative of PwC Wirtschaftsprüfung GmbH is expected to be present at the Annual Meeting with the opportunity to make a statement if he or she desires and to respond to appropriate questions.
The Company’s organizational documents do not require that the stockholders ratify the selection of PwC Wirtschaftsprüfung GmbH as the Company’s independent registered public accounting firm. The Company requests such ratification as a matter of good corporate practice. The selection of PwC Wirtschaftsprüfung GmbH as our independent registered public accounting firm will be ratified if the votes cast FOR exceed the votes cast AGAINST the proposal. Brokers, bankers and other nominees have discretionary voting power on this routine matter. Abstentions and broker non-votes will have no effect on the ratification. We do not expect there to be broker non-votes on this proposal. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether to retain PwC Wirtschaftsprüfung GmbH, but still may retain this firm. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

​
Pre-Approval Policies and Procedures
The Company’s Audit Committee has adopted procedures requiring the pre-approval of all non-audit services performed by the Company’s independent registered public accounting firm in order to assure that these services do not impair the auditor’s independence. These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is to be reviewed, and if necessary modified, at least annually. Management must obtain the specific prior approval of the audit committee for each engagement of the independent registered public accounting firm to perform other audit-related or other non-audit services. The Audit Committee does not delegate its responsibility to approve services performed by the independent registered public accounting firm to any member of management.
The standard applied by the Audit Committee in determining whether to grant approval of any type of non-audit service, or of any specific engagement to perform a non-audit service, is whether the services to

​
 
be performed, the compensation to be paid therefore and other related factors are consistent with the independent registered public accounting firm’s independence under guidelines of the SEC and applicable professional standards. Relevant considerations include whether the work product is likely to be subject to, or implicated in, audit procedures during the audit of our financial statements, whether the independent registered public accounting firm would be functioning in the role of management or in an advocacy role, whether the independent registered public accounting firm’s performance of the service would enhance our ability to manage or control risk or improve audit quality, whether such performance would increase efficiency because of the independent registered public accounting firm’s familiarity with our business, personnel, culture, systems, risk profile and other factors, and whether the amount of fees involved, or the non-audit services portion of the total fees payable to the independent registered public accounting firm in the period would tend to reduce the independent registered public accounting firm’s ability to exercise independent judgment in performing the audit.
All of the services rendered by PwC Wirtschaftsprüfung GmbH with respect to the 20222023 and 20212022 fiscal years were pre-approved by the audit committee in accordance with this policy.
Vote Required and Board of Directors Recommendation
For Proposal 2, a majority of the votes properly cast is required to ratify the appointment of PwC Wirtschaftsprüfung GmbH as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2023. Abstentions and broker non-votes, if any, will have no effect on the outcome of the vote.2024.

CORPORATE GOVERNANCEPROPOSAL 3: AUTHORIZATION OF THE BOARD OF DIRECTORS TO AMEND OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE COMPANY’S AUTHORIZED SHARES OF COMMON STOCK TO 400,000,000 SHARES
Code of Business Conduct and Ethics
We are committed to the highest standards of integrity and ethics in the way we conduct our business. In 2019,On April 15, 2024, our Board of Directors adopted a Code of Business Conduct and Ethics, which appliesunanimously approved, subject to stockholder approval, an amendment to our directors, officersAmended and employees, including our Chief Executive Officer, our principal financial officer, those officers responsibleRestated Certificate of Incorporation (the “Charter”) to increase the number of shares of common stock authorized under the Charter for financial reporting,issuance by 200,000,000 shares of common stock, bringing the total number of shares of common stock authorized to 400,000,000 shares. The text of the proposed amendment (the “Charter Amendment”) to the Amended and our other executiveRestated Certificate of Incorporation is attached hereto as Annex A. This proposal to increase the number of shares of common stock authorized for issuance, if approved, will become effective and senior officers. the Company’s number of shares of authorized common stock will be increased to 400,000,000 shares upon the filing of the Charter Amendment with the Secretary of State of Delaware. The following discussion is qualified in its entirety by the full text of the Charter Amendment, which is incorporated herein by reference.
Reasons for the Increase
Our Codeshare usage (i.e., the number of Business Conduct and Ethics establishes our policies and expectations with respect to a wide range of business conduct, including the preparation and maintenanceoutstanding shares of our financial and accounting information, our compliance with laws, and possible conflictscommon stock plus the number of interest.
Under our Code of Business Conduct and Ethics, eachshares of our directors and employeescommon stock that are reserved for future issuance) is required to report suspected or actual violations tocurrently approximately 70% of the extent permitted by law. In addition, we have adopted separate procedures concerning the receipt and investigationsnumber of complaints relating to accounting or audit matters. These procedures have been adopted by theshares of common stock authorized in our Charter. Our Board of Directors believes that it is desirable to have additional authorized shares of common stock available for possible future financings, equity compensation, acquisitions and are administered by our Audit Committee.
A current copyother general corporate purposes. Our Board of our CodeDirectors believes that having such additional authorized shares of Business Conduct and Ethics is posted oncommon stock available for issuance under the Governance section of our website, which is located at https://hookipapharma.com. If we make any substantive amendments to, or grant any waivers from, the Code of Business Conduct and Ethics for any officer or director, weCharter will disclose the nature of such amendment or waiver on our website or in a Current Report on Form 8-K.
Insider Trading Policy Prohibitions and Hedging Policy
Our company maintains an Insider Trading Policy that prohibits our officers, directors, employees and designated consultants and contractors who in the course of the performance of their duties have access to material, nonpublic information regardinggive the Company from engagingincreased flexibility and would allow such shares to be issued without the expense and delay of a special stockholders’ meeting unless such approval is expressly required by applicable law.
There are certain advantages and disadvantages of an increase in the following transactions:authorized common stock. Advantages include:
•
selling any of our securities that they do not own at the time of the sale (a “short sale”);
​
•
buying or selling puts, calls, other derivatives of the Company or any derivative securities that provide the economic equivalent of ownership of any of our securities or an opportunity, direct or indirect,The ability to profit from any changeraise capital by issuing capital stock in the valuetype of the Company’s securitiestransactions described above, or engage in any other hedging transaction with respect to the Company’s securities, at any time;
​
•
using our securities as collateral in a margin account;financing transactions; and
​
•
pledgingHaving shares of common stock available to pursue certain business combinations or other expansion opportunities, if any.
​
The disadvantages of an increase in authorized common stock include the following:
•
The increase in the number of authorized but unissued stock could, under certain circumstances, have anti-takeover implications. The additional shares of common stock that would become available for issuance if this proposal is approved could be used to deter or oppose a potential takeover of the Company or a change in management that may otherwise be beneficial to stockholders by diluting the shares held by a potential suitor or issuing shares to a stockholder that will vote in accordance with our securities as collateralBoard of Directors’ desires. A takeover may be beneficial to independent stockholders because, among other reasons, a potential suitor may offer such stockholders a premium for a loan (or modifying an existing pledge).their shares of stock compared to the then-existing market price. The Company does not have any plans or proposals to adopt provisions or enter into agreements that may have material anti-takeover consequences.
​
•
Our stockholders do not have any preemptive or similar rights to subscribe for or purchase any additional shares of common stock that may be issued in the future, and therefore, future issuances of common stock may, depending on the circumstances, have a dilutive effect on the earnings per share, voting power and other interests of existing stockholders of the Company.
​
Although an increase in the authorized shares of common stock could, under certain circumstances, have an anti-takeover effect, this proposal to adopt the amendment is not in response to any effort of which the Company is aware to accumulate common stock or obtain control of the Company. Nor is it part of a plan by management to recommend a series of similar amendments to the Board Diversity

result of the effectiveness of the amendment to our Amended and Restated Certificate of Incorporation to increase the authorized number of shares of our common stock. However, it is highly likely that we will issue additional shares in the future.
If the Company’s stockholders do not approve the increase in authorized shares of common stock, then the Company will not be able to increase the total number of authorized shares of common stock from 200,000,000 to 400,000,000, and therefore, the Company would be limited in its ability to use authorized shares of common stock for financings, acquisitions, issuing equity awards or other general corporate purposes.
Our directors and executive officers have no substantial interests, directly or indirectly, in the matters set forth in this proposed amendment, except to the extent of their ownership in shares of our common stock and securities convertible or exercisable for common stock.
Concurrent Approval of Reverse Stock Split
Concurrently with the proposal to approve an increase in the authorized shares of common stock, the Company’s stockholders are also being asked to approve a reverse stock split at a ratio of any whole number between 1-for-2 and 1-for-10, as determined by our Board of Directors, and an amendment to the Company’s Amended and Restated Certificate of Incorporation to implement the reverse stock split at any time prior to June 17, 2025, if and as determined by the Board of Directors (see Proposal 4 below). Approval of this proposal would grant the Board of Directors the authority (but not the obligation), without further action by the stockholders, to carry out such action any time prior to June 17, 2025, one year from the date of the Annual Meeting.
If the Reverse Split Proposal is approved by the Company’s stockholders and a reverse stock split is effectuated, a reverse stock split would reduce, on a proportionate basis for each stockholder, the aggregate number of shares of common stock outstanding with a proportionate reduction in the total number of shares of common stock authorized for issuance, whether or not such number remains at 200,000,000 or is increased to 400,000,000 by this proposal.
The current proposal to increase the number of authorized shares of common stock to 400,000,000 has no bearing on our Board of Directors’ ability to effect a reverse stock split, if concurrently authorized by stockholders pursuant to the Reverse Split Proposal (Proposal 4) below. Our Board of Directors’ determination as to whether to effect a reverse stock split and, if so, at what ratio, would be based on the same factors reported in the Reverse Split Proposal below. Notwithstanding approval of the proposed amendment by our stockholders, our Board of Directors may, at its sole option, abandon the proposed amendment and determine prior to the effectiveness of any filing with the Secretary of State of the State of Delaware not to effect any reverse stock split, as permitted under Section 242(c) of the General Corporation Law of the State of Delaware.
Vote Required and Board of Directors Recommendation
Pursuant to the Delaware General Corporation Law and our Amended and Restated Certificate of Incorporation, this proposal must be approved by the affirmative vote of a majority of the outstanding shares of common stock entitled to vote on the proposal.

PROPOSAL 4: AUTHORIZATION OF THE BOARD OF DIRECTORS TO AMEND OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO EFFECT A REVERSE STOCK SPLIT OF OUR COMMON STOCK IN THE RANGE OF 1-FOR-2 TO 1-FOR-10
On April 15, 2024, the Board of Directors unanimously adopted resolutions approving, declaring advisable and recommending to the stockholders for their approval a proposal to authorize the Board of Directors, in its discretion, to amend our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our issued and outstanding common stock at a ratio in the range of one-for-two to not more than one-for-ten at any time prior to June 17, 2025, such ratio to be determined by the Board of Directors. The form of proposed amendment to our Amended and Restated Certificate of Incorporation to effect a reverse stock split is set forth on Annex B (subject to any changes required by applicable law). Pursuant to the General Corporation Law of Delaware, our state of incorporation, the Board of Directors must adopt any amendment to our Amended and Restated Certificate of Incorporation and submit the amendment to our stockholders for their approval. Approval of this proposal will grant the Board of Directors the authority (but not the obligation), without further action by the stockholders, to carry out such action any time prior to June 17, 2025, one year from the date of the Annual Meeting.
Purpose of the Reverse Stock Split
The Board of Directors is submitting the proposed authorization for a reverse stock split to our stockholders for approval in order to obtain the flexibility to reduce the number of issued and outstanding shares and to potentially increase the per share trading price of our common stock. The Board of Directors believes that having the possibility to effect the proposed reverse stock split is desirable and should be approved by our stockholders for a number of reasons, including, without limitation, the following:
•
The flexibility to effect a reverse stock split would help us to maintain our listing on Nasdaq. By potentially increasing the per share trading price of our common stock, the reverse stock split would reduce the risk that our common stock could be delisted from Nasdaq. On August 3, 2023, we were notified by Nasdaq that the bid price for our common stock had closed below $1.00 per share for 30 consecutive business days and, as a result, we no longer satisfied the minimum bid price requirement applicable to The Nasdaq Global Select Market issuers. Pursuant to Nasdaq rules, we were automatically afforded an initial 180-calendar day grace period, through January 30, 2024, to regain compliance with the minimum bid price requirement. To obtain a second 180-day grace period, we applied to transfer the listing of our common stock to The Nasdaq Capital Market, which was approved and effective on January 31, 2024. Our failure to regain compliance during this period could result in delisting. To regain compliance with the minimum bid price requirement, we must evidence a closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days.
​
•
If we are successful in maintaining a higher stock price, it may improve the perception of our common stock as an investment security and may generate greater interest among a broader range of institutional and other professional investors and institutions in us, as we have been advised that the current market price of our common stock may affect its acceptability to certain members of the investing public. Many institutional investors have policies prohibiting them from holding lower-priced stocks in their portfolios, which reduces the number of potential purchasers of our common stock. Investment funds may also be reluctant to invest in lower-priced stocks. Investors may also be dissuaded from purchasing lower-priced stocks because the brokerage commissions, as a percentage of the total transaction, tend to be higher for such stocks. Moreover, the analysts at many brokerage firms do not monitor the trading activity or otherwise provide coverage of lower-priced stocks. Giving the Board of Directors the ability to effect a reverse stock split, and thereby potentially increasing the price of our common stock, would give the Board of Directors the ability to address these issues if it is deemed necessary.
​
•
The Board of Directors believes that the increased market price of the common stock that may potentially be the result of implementing the reverse stock split could improve the marketability of our common stock, which could allow us to raise additional capital and in turn permit us to satisfy the minimum stockholders’ equity requirement imposed by Nasdaq listing rules.
​
•
The reverse stock split could decrease price volatility for our common stock, as small price movements currently may cause relatively large percentage changes in our stock price.
​

41
​

•
The reverse stock split may help increase analyst and broker interest in our stock, as their policies can discourage them from following or recommending companies with lower stock prices. Because of the trading volatility often associated with lower-priced stocks, many brokerage houses and institutional investors have adopted internal policies and practices that either prohibit or discourage them from investing in such stocks or recommending them to their customers.
​
•
A higher market price per share for our common stock may help us attract and retain employees because some potential employees are less likely to work for a company with a low stock price, regardless of our market capitalization.
​
•
The availability of additional shares of common stock would provide us with the flexibility to consider and respond to future business opportunities and needs as they arise, including equity offerings and other issuances, mergers, business combinations or other strategic transactions, asset acquisitions, stock dividends, stock splits and other corporate purposes.
​
Accordingly, for these reasons we believe that granting the Board of Directors the flexibility to effect the reverse stock split is in our and our stockholders’ best interests.
Reducing the number of outstanding shares of our common stock through the reverse stock split is intended, absent other factors, to increase the per share market price of our common stock. A number of the anticipated benefits of the proposed reverse stock split discussed above are contingent upon the split resulting in an increase in the per share market price of our common stock. However, other factors, such as our financial results, market conditions and the market perception of our business may adversely affect the market price of our common stock. As a result, there can be no assurance that the reverse stock split, if completed, would result in the intended benefits described above, that the market price of our common stock will increase following the reverse stock split or that the market price of our common stock will not decrease in the future. Additionally, we cannot assure you that the market price per share of our common stock after a reverse stock split will increase in proportion to the reduction in the number of shares of our common stock outstanding before the reverse stock split. Accordingly, the total market capitalization of our common stock after the reverse stock split may be lower than the total market capitalization before the reverse stock split.
Concurrent Approval of Authorized Stock Increase
Concurrently with the reverse stock split proposal, the Company’s stockholders are also being asked to approve an amendment to our certificate of incorporation to increase the total number of authorized shares of common stock from 200,000,000 shares to 400,000,000 shares (see Proposal 3 above). The current proposal to approve a reverse stock split has no bearing on our ability to effect an increase in the number of shares authorized for issuance if concurrently authorized by stockholders pursuant to Proposal 3 above.
Certain Risks Associated with the Reverse Stock Split
The reverse stock split may not increase the price of the common stock.
Although the Board of Directors expects that a reverse stock split will result in an increase in the price of our common stock, the effect of a reverse stock split cannot be predicted with certainty. Other factors, such as our financial results, market conditions and the market perception of our business, may adversely affect the stock price. As a result, there can be no assurance that the reverse stock split, if completed, will result in any of the intended benefits described above, that the stock price will increase as a result of or following the reverse stock split (or will increase in the same proportion as the final reverse stock split ratio) or that the stock price will not decrease in the future.
If the reverse stock split is implemented, the resulting per-share price may not attract institutional investors, investment funds or brokers and may not satisfy the investing guidelines of these investors or brokers, and consequently, the trading liquidity of our common stock may not improve.
While we believe that a higher share price may help generate investor and broker interest in the common stock, the reverse stock split may not result in a share price that will attract institutional investors or investment funds or satisfy the investing guidelines of institutional investors, investment funds or brokers.

42
​

For example, some investors, analysts and other stock market participants have a negative perception of reverse stock splits due to: (1) the fact that the stock price of some companies that have effected reverse stock splits has subsequently declined in share price and corresponding market capitalization, (2) the potential that the reduction in shares outstanding could adversely impact the liquidity of our common stock; and (3) the costs associated with implementing a reverse stock split.
The reverse stock split may leave certain stockholders with “odd lots.”
The reverse stock split may result in some stockholders owning “odd lots” of fewer than 100 shares of the common stock. Odd lot shares may be more difficult to sell, and brokerage commissions and other costs of transactions in odd lots are generally somewhat higher than the costs of transactions in “round lots” of even multiples of 100 shares.
Board Discretion to Implement the Reverse Stock Split
The Board of Directors believes that stockholder approval of a range of reverse stock split ratios (rather than a single exchange ratio) is in the best interests of our stockholders because it provides the Board of Directors with the flexibility to achieve the desired results of the reverse stock split and because it is not possible to predict market conditions at the time the reverse stock split would be implemented. If stockholders approve this proposal, the Board of Directors would have the authority, but not the obligation, in its sole discretion and without any further action on the part of the stockholders, to carry out a reverse stock split only upon the Board of Directors’ determination that a reverse stock split would be in the best interests of our stockholders at that time. The reverse stock split, if implemented, would be effected at a time that the Board of Directors determines to be most advantageous to us and to our stockholders. The Board of Directors would then set the ratio for the reverse stock split within the range approved by stockholders and in an amount it determines is advisable and in the best interests of the stockholders considering relevant market conditions at the time the reverse stock split is to be implemented. In determining the ratio, following receipt of stockholder approval, the Board of Directors may consider, among other things:
•
the historical prices and trading volume of our common stock;
​
•
the then-prevailing trading price and trading volume of our common stock and the anticipated impact of the reverse stock split on the trading market for our common stock;
​
•
the outlook for the trading price of our common stock;
​
•
threshold prices of brokerage houses or institutional investors that could impact their ability to invest or recommend investments in our common stock;
​
•
our stockholders’ equity at such time; and
​
•
prevailing general market and economic conditions.
​
Although approval of this proposal would provide the Board of Directors with the authority to carry out a reverse stock split, the Board of Directors is not obligated to do so. Notwithstanding approval of the proposed amendment by our stockholders, our Board of Directors may, at its sole option, abandon the proposed amendment and determine prior to the effectiveness of any filing with the Secretary of State of the State of Delaware not to effect any reverse stock split, as permitted under Section 242(c) of the General Corporation Law of the State of Delaware. If the Board of Directors fails to implement the reverse stock split on or prior to June 17, 2025, the first anniversary date of the Annual Meeting, stockholder approval again would be required prior to implementing any reverse stock split.
Our directors and executive officers have no substantial interests, directly or indirectly, in the matters set forth in this proposed amendment, except to the extent of their ownership in shares of our common stock and securities convertible or exercisable for common stock.
Procedures for Effecting the Reverse Stock Split and Filing Amended and Restated Certificate of Incorporation to Effect the Reverse Stock Split
If our stockholders approve the reverse stock split, the Board of Directors will have discretion as to whether or not to effect the reverse stock split at any time prior to June 17, 2025, the first anniversary date

​

of the Annual Meeting]. If implemented by the Board of Directors, the reverse stock split would become effective upon the filing of the amendment to our Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. The actual timing of any such filing will be made by the Board of Directors at such time as the Board of Directors believes to be most advantageous to us and our stockholders.

Effect on Existing Common Stock
Although the reverse stock split will not have any dilutive effect on our stockholders (other than de minimis adjustments that may result from the treatment of fractional shares), if the Reverse Split Proposal is approved by the Company’s stockholders and a reverse stock split is effectuated, the reverse stock split would reduce, on a proportionate basis for each stockholder, the aggregate number of shares of common stock outstanding with a proportionate reduction in the total number of shares of common stock authorized for issuance.
As described below under “Mechanics of the Reverse Stock Split — Fractional Shares,” cash will be paid in lieu of the issuance of fractional shares. Subject to the treatment of fractional shares, (1) the change in the number of shares of common stock outstanding that will result from the reverse stock split will not affect any stockholder’s percentage ownership in the Company, and (2) the relative voting and other rights that accompany the shares of common stock will not be affected by the reverse stock split.
After the reverse stock split, we will continue to be subject to the periodic reporting and other requirements of the Exchange Act. Assuming we are otherwise able to maintain our listing on the Nasdaq Capital Market, our common stock will continue to be listed on the Nasdaq Capital Market under the symbol “HOOK,” although the exchange will add the letter “D” to the end of the trading symbol for a period of 20 trading days after the effective time to indicate that a reverse stock split has occurred. Following the reverse stock split, our common stock will have a new CUSIP number.
Upon the filing of the certificate of amendment, and without any further action on the part of the Company or our stockholders, the issued shares of common stock held by stockholders of record as of the effective date of the reverse stock split would be converted into a lesser number of shares of common stock calculated in accordance with the reverse stock split ratio.
Beginning on the effective date of the split, each certificate representing pre-split shares would be deemed for all corporate purposes to evidence ownership of post-split shares. As soon as practicable after the effective date of the reverse stock split, stockholders would be notified that the reverse stock split had been effected.
Effect on Existing Preferred Stock
The total authorized shares of Preferred Stock is 10,000,000. As of April 22, 2024, 370 shares of Series A Convertible Preferred Stock were outstanding, 10,800 shares of Series A-1 Convertible Preferred Stock were outstanding and 15,268 shares of Series A-2 Convertible Preferred Stock were outstanding. Each share of Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock is currently convertible into 1,000 shares of common stock, and we have reserved 26,438,000 shares of common stock for issuance upon the conversion of our outstanding shares of Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock. Pursuant to the terms of the Certificate of Designations of Series A Convertible Preferred Stock, Certificate of Designations of Series A-1 Convertible Preferred Stock and Certificate of Designations of Series A-2 Convertible Preferred Stock, if we combine our outstanding shares of common stock into a smaller number of shares, as contemplated by the reverse stock split, the conversion rate of the Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock will be proportionately adjusted. Accordingly, upon effectiveness of the reverse stock split, the number of shares of common stock issuable upon conversion of the Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock will be decreased in accordance with the applicable split ratio and we will proportionately decrease the number of shares of common stock

44
​

reserved for issuance upon conversion of the Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock. However, the total number of authorized shares of Preferred Stock, Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock and the actual number of outstanding shares of Series A Convertible Preferred Stock, Series A-1 Convertible Preferred Stock and Series A-2 Convertible Preferred Stock will remain unchanged upon the effectiveness of the reverse stock split. Other than as described in this paragraph, all of the rights, preferences and other privileges of our Preferred Stock will remain unchanged following the reverse stock split.
Effect on Equity Compensation Plans
The proposed reverse stock split will reduce the number of shares of common stock available for issuance under our 2019 Stock Option and Incentive Plan (“2019 Plan”), our 2019 Employee Stock Purchase Plan (“ESPP”) and our 2023 Inducement Plan (“2023 Inducement Plan”) in proportion to the applicable split ratio if the reverse stock split is effected.
Under the terms of the 2019 Plan, the Board of Directors or the Compensation Committee shall make an appropriate and proportionate adjustment in (i) the maximum number of shares reserved for issuance under the 2019 Plan, including the maximum number of shares that may be issued in the form of incentive stock options, (ii) the number and kind of shares or other securities subject to any then outstanding awards under the 2019 Plan, (iii) the repurchase price, if any, per share subject to each restricted stock award and (iv) the exercise price for each share subject to any then outstanding stock options and stock appreciation rights under the 2019 Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of shares subject to stock options and stock appreciation rights) as to which such stock options and stock appreciation rights remain exercisable. No fractional shares shall be issued under the 2019 Plan resulting from any such adjustment, but the Board of Directors or the Compensation Committee in its discretion may make a cash payment in lieu of fractional shares.
Under the terms of the ESPP, in the event of a subdivision of outstanding shares of common stock, the payment of a dividend in common stock or any other change affecting the common stock, the number of shares approved for the ESPP and the limitation on the number of shares an eligible employee is permitted to purchase under the ESPP shall be equitably or proportionately adjusted to give proper effect to such event.
Under the terms of the 2023 Inducement Plan, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in our capital stock, the outstanding shares of common stock are increased or decreased or are exchanged for a different number or kind of shares or other of our securities, the Board of Directors or the Compensation Committee shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the 2023 Inducement Plan, (ii) the number and kind of shares or other securities subject to any then outstanding awards under the 2023 Inducement Plan, (iii) the repurchase price, if any, per share subject to each outstanding restricted stock award, and (iv) the exercise price for each share subject to any then outstanding stock options and stock appreciation rights under the 2023 Inducement Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of shares subject to stock options and stock appreciation rights) as to which such stock options and stock appreciation rights remain exercisable. The adjustment by the Board of Directors or the Compensation Committee shall be final, binding and conclusive. No fractional shares of common stock shall be issued under the 2023 Inducement Plan resulting from any such adjustment, but the Board of Directors or the Compensation Committee in its discretion may make a cash payment in lieu of fractional shares.
Summary of Effects on our Capital Stock
The following tables contain approximate information relating to our common stock, our class A common stock, our Preferred Stock, outstanding options to purchase our common stock and shares of our common stock reserved for future issuance under our equity compensation plans under each of the possible split ratios (without giving effect to the treatment of fractional shares discussed below in “Mechanics of the Reverse Stock Split-Fractional Shares” and without giving effect to Proposal 3), based on share information as of April 22, 2024.

Accounting Matters
If the reverse stock split is implemented, the par value per share of our common stock will remain unchanged at $0.0001 per share after the reverse stock split. As a result of the reverse stock split, at the effective time of the reverse stock split, the stated capital on our balance sheet attributable to the common stock, which consists of the par value per share of the common stock multiplied by the aggregate number of shares of the common stock issued and outstanding, will be reduced in proportion to the reverse stock split ratio. Correspondingly, our additional paid-in capital account, which consists of the difference between our stated capital and the aggregate amount paid to us upon issuance of all currently outstanding shares of common stock, will be credited with the amount by which the stated capital is reduced. Our stockholders’ equity, in the aggregate, will remain unchanged. In addition, the per share net income or loss of our common stock, for all periods, will be restated because there will be fewer outstanding shares of common stock.
No Going Private Transaction
Notwithstanding the decrease in the number of outstanding shares following the reverse stock split, this transaction is not intended to be the first step in a “going private transaction,” within the meaning of Rule 13e-3 of the Exchange Act, and will not produce, either directly or indirectly, any of the effects described in paragraph (a)(3)(ii) of Rule 13e-3 of the Exchange Act.
Effective Date
If the reverse stock split is implemented, we will file a Certificate of Amendment of our Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. The reverse stock

48
​

split will become effective upon the filing of the Certificate of Amendment. No further action on the part of stockholders would be required to either effect or abandon the reverse stock split. If the Board of Directors does not implement the reverse stock split on or prior to June 17, 2025, the one-year anniversary of the date of the Annual Meeting, the authority granted in this proposal to implement the reverse stock split will terminate. The Board of Directors reserves its right to elect not to proceed with the reverse stock split, and to abandon the reverse stock split in its entirety, if it determines, in its sole discretion, that this proposal is no longer in the best interests of our stockholders.
Mechanics of the Reverse Stock Split
Exchange of Stock Certificates
If the reverse stock split is implemented, each certificate representing pre-reverse split shares will, until surrendered and exchanged as described below, for all corporate purposes, be deemed to represent, respectively, only the number of post-reverse stock split shares.
Shortly after the reverse stock split becomes effective, stockholders will be notified and offered the opportunity at their own expense to surrender their current certificates to our transfer agent in accordance with the procedures to be set forth in a letter of transmittal to be sent by us or our transfer agent in exchange for the issuance of new certificates reflecting the reverse stock split. In connection with the reverse stock split, the CUSIP number for the common stock will change from its current CUSIP number. This new CUSIP number will appear on any new stock certificates issued representing post-reverse stock split shares.
STOCKHOLDERS SHOULD NOT DESTROY ANY STOCK CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY STOCK CERTIFICATE(S) UNTIL REQUESTED TO DO SO.
Effect on Registered “Book-entry” Holders of Common Stock
Holders of common stock may hold some or all of their common stock electronically in book-entry form (“street name”). These stockholders do not have stock certificates evidencing their ownership. They are, however, provided with a statement reflecting the number of shares of common stock registered in their accounts. If the reverse stock split is implemented and you hold registered common stock in book-entry form, you do not need to take any action to receive your post-reverse stock split shares or cash payment in lieu of any fractional share interest, if applicable. If you are entitled to post-reverse stock split shares, a transaction statement will automatically be sent to your address of record indicating the number of shares you hold. If you are entitled to a payment in lieu of any fractional share interest, a check will be mailed to you at your registered address as soon as practicable after our transfer agent completes the aggregation and sale described below in “Fractional Shares.”
Effect on Registered Certificated Common Stockholders
Some of our stockholders hold their shares of common stock in certificate form or a combination of certificate and book-entry form. If the reverse stock split is implemented and any of your shares are held in certificate form, you will receive a transmittal letter from us or our transfer agent as soon as practicable after the effective date of the reverse stock split. The letter of transmittal will contain instructions on how to surrender your certificate(s) representing your pre-reverse common stock split shares to the transfer agent. Upon receipt of your pre-reverse stock split certificate(s), you will be issued the appropriate number of shares electronically in book-entry form, and if you are entitled to a payment in lieu of any fractional share interest, payment will be made as described below under “Fractional Shares.” No new shares in book-entry form will be issued and no payment in lieu of any fractional share interest will be made to you until you surrender your outstanding pre-reverse stock split certificate(s), together with the properly completed and executed letter of transmittal, to our transfer agent. At any time after receipt of your book-entry statement, you may request a stock certificate representing your ownership interest.
Fractional Shares
If the reverse stock split is implemented, no fractional shares will be issued in connection with the reverse stock split. Instead, stockholders who would otherwise hold fractional shares because the number of

49
​

shares of common stock they hold before the reverse stock split is not evenly divisible by the split ratio ultimately selected by the Board of Directors will receive cash (without interest) in lieu of such fractional shares in an amount equal to the product obtained by multiplying (i) the closing price of our shares of common stock on the day immediately preceding the effective date of the reverse split, as reported on the Nasdaq Capital Market (or, if the closing price of our common stock is not then reported on the Nasdaq Capital Market, then the fair market value of our shares of common stock as determined by the Board of Directors) by (ii) the number of shares of our common stock held by such stockholder that would otherwise have been exchanged for such fractional share interest. Stockholders who own their shares in certificated form will receive such cash payment in lieu of fractional shares following the surrender of their pre-reverse split certificate(s) for post-reverse stock split shares. The ownership of a fractional share interest will not give the holder any voting, dividend or other rights, except to receive the above-described cash payment.
Dissenters’ or Appraisal Rights
Under the General Corporation Law of the State of Delaware, our stockholders are not entitled to any dissenters’ or appraisal rights with respect to the reverse stock split, and we will not independently provide stockholders with any such right.
U.S. Federal Income Tax Consequences of the Reverse Stock Split
The following summary describes certain material U.S. federal income tax consequences of the reverse stock split to holders of our common stock.
Unless otherwise specifically indicated herein, this summary addresses the U.S. federal income tax consequences only to a beneficial owner of our common stock that is: (i) a citizen or individual resident of the United States, (ii) a corporation (including an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the U.S. or of a political subdivision thereof (including the District of Columbia), (iii) an estate whose income is subject to U.S. federal income taxation, regardless of its source, or (iv) any trust if: (a) a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (b) it has a valid election in place to be treated as a U.S. person (each, a “U.S. Holder”). This summary does not address any state, local, foreign, or other tax consequences, nor does it address all of the tax consequences that may be relevant to a particular stockholder in light of its circumstances, including tax consequences arising to stockholders subject to special rules, such as persons who acquired shares of our common stock pursuant to employee stock options or otherwise as compensation, certain financial institutions, tax-exempt entities, regulated investment companies, insurance companies, partnerships or other pass-through entities, U.S. expatriates, persons subject to the alternative minimum tax, traders in securities that elect to use a mark-to-market method of accounting, individual retirement accounts or tax-deferred accounts, dealers in securities, commodities or currencies, persons holding shares in connection with a hedging transaction, “straddle,” conversion transaction or a synthetic security or other integrated transaction, stockholders whose “functional currency” is not the U.S. dollar, and persons that do not hold our common stock as “capital assets” ​(generally, property held for investment).
This summary is based on current law, including the Internal Revenue Code of 1986, as amended (the “Code”), administrative pronouncements, judicial decisions, existing and proposed Treasury Regulations, and interpretations of the foregoing, all as in effect as of the date hereof. All of the foregoing authorities are subject to change (possibly with retroactive effect) and any such change may result in U.S. federal income tax consequences to a stockholder that are materially different from those described below. In addition, we have not sought, and will not seek, an opinion of counsel or a ruling from the Internal Revenue Service (the “IRS”) regarding the U.S. federal income tax consequences of the reverse stock split, and there can be no assurance the IRS will not challenge the statements and conclusions set forth in this discussion or that a court would not sustain any such challenge.
Tax Consequences of the Reverse Stock Split Generally
The reverse stock split is intended to constitute a “reorganization” within the meaning of Section 368 of the Code. Accordingly, a U.S. Holder generally will not recognize gain or loss for U.S. federal income tax purposes on the reverse stock split (except with respect to any cash received in lieu of a fractional share as

50
​

described below). The aggregate tax basis of the post-reverse split shares received will be the same as the aggregate tax basis of the pre-reverse split shares exchanged therefore (excluding any portion of the U.S. Holder’s basis allocated to fractional share interests), and the holding period(s) of the post-reverse split shares received will include the U.S. Holder’s holding period(s) for the pre-reverse split shares exchanged. The Company will not recognize any gain or loss as a result of the reverse stock split.
Cash Received Instead of a Fractional Share
A U.S. Holder who receives cash for fractional shares should generally recognize gain or loss, as the case may be, for U.S. federal income tax purposes measured by the difference between the amount of cash received and the portion of the tax basis of the pre-reverse split shares allocated to the fractional share interest. Such gain or loss will be capital gain or loss and will generally be long-term capital gain or loss to the extent such U.S. Holder’s holding period exceeds 12 months. The deductibility of capital losses may be subject to certain limitations.
Backup Withholding
A non-corporate U.S. Holder may be subject to backup withholding at a 24% rate on cash payments received pursuant to the reverse stock split unless such U.S. Holder provides a correct taxpayer identification number to its broker or to the Company and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. Rather, any amount withheld under these rules will be creditable against the U.S. Holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS.
PLEASE CONSULT YOUR OWN TAX ADVISOR REGARDING THE FEDERAL, STATE, LOCAL, AND FOREIGN INCOME AND OTHER TAX CONSEQUENCES TO YOU OF THE REVERSE STOCK SPLIT IN YOUR PARTICULAR CIRCUMSTANCES.
Vote Required and Board of Directors Recommendation

STOCKHOLDER PROPOSALS
Stockholder Recommendations for Director Nominations and Other Business
Our amended and restated bylaws provide that, for nominations of persons for election to our Board of Directors or other proposals to be considered at an annual meeting of our stockholders, a stockholder must give written notice to our corporate secretary at HOOKIPA Pharma Inc., 350 Fifth Avenue, 72nd Floor, New York, New York 10118, not later than the close of business 90 days, nor earlier than the close of business 120 days, prior to the first anniversary of the date of the preceding year’s annual meeting. However, our amended and restated bylaws also provide that in the event the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice must be delivered not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made.
