Important Notice Regarding the Availability of Proxy Materials for the 2024 Annual General Meeting of Shareholders to Be Held on June 5, 2024. The Proxy Statement and Annual Report for the year ended December 31, 2023 are available at www.proxyvote.com.

Forward-Looking Statements. The Proxy Statement may contain “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, which statements are subject to substantial risks and uncertainties and are based on estimates and assumptions. All statements other than statements of historical fact included in the Proxy Statement, including statements about the Company’s Board of Directors, corporate governance practices, executive compensation program, equity compensation utilization and environment, social and governance (“ESG”) initiatives, are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may”, “might”, “will”, “objective”, “intend”, “should”, “could”, “can”, “would”, “expect”, “believe”, “design”, “estimate”, “predict”, “potential”, “plan”, or the negative of these terms, and similar expressions intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from the forward-looking statements expressed or implied in the Proxy Statement. Such risks, uncertainties and other factors include those risks described in “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s most recent Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) and other subsequent documents we file with the SEC. The Company expressly disclaims any obligation to update or alter any statements whether as a result of new information, future events or otherwise, except as required by law.

Website References. Website references throughout this document are inactive textual references and provided for convenience only, and the content on the referenced websites is not incorporated herein by reference and does not constitute a part of the Proxy Statement.

Use of Trademarks. MoonLake is the trademark of MoonLake Immunotherapeutics. Other names and brands may be claimed as the property of others.

We are making these proxy materials available to you in connection with the solicitation of proxies by the Board of Directors (the “Board”) of MoonLake Immunotherapeutics (“we”, “us”, “our” or the “Company”) for use at the 2024 Annual General Meeting of Shareholders (the “Annual Meeting”) to be held on June 5, 2024 at 8:00 a.m. Eastern Time, or at any other time following adjournment or postponement thereof. You are invited to attend the Annual Meeting at the offices of Gibson, Dunn & Crutcher LLP, located at 200 Park Avenue, New York, New York 10166 and to vote on the proposals described in this Proxy Statement. The proxy materials are first being made available to our shareholders on or about April 24, 2024.

Pursuant to U.S. Securities and Exchange Commission (“SEC”) rules, we are furnishing the proxy materials to our shareholders primarily via the Internet instead of mailing printed copies. This process allows us to expedite our shareholders’ receipt of proxy materials, lower the costs of printing and mailing the proxy materials and reduce the environmental impact of our Annual Meeting. If you received a Notice of Internet Availability of Proxy Materials (the “Notice”), you will not receive a printed copy of the proxy materials unless you request one. The Notice provides instructions on how to access the proxy materials for the Annual Meeting via the Internet, how to request a printed set of proxy materials and how to vote your shares.

Only shareholders of record at the close of business on April 11, 2024 (the “Record Date”) are entitled to notice of the Annual Meeting and to vote on the proposals described in this Proxy Statement. At the close of business on the Record Date, 62,874,637 shares of our Class A Ordinary Shares and 995,267 shares of our Class C Ordinary Shares were issued and outstanding. Each Class A and Class C Ordinary Share is entitled to one vote on each proposal to be voted on at the Annual Meeting.

If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered to be, with respect to those shares, the registered shareholder, and these proxy materials are being sent directly to you by us.

If your shares are held by a broker, fiduciary or custodian, you are considered the beneficial owner of shares held in “street name”, and these proxy materials are being forwarded to you from that broker, fiduciary or custodian.

The proposals to be voted on at the Annual Meeting are as follows:

The Board recommends that you vote your shares “FOR” each director nominee in Proposal 1, “FOR” Proposals 2 and 3 and every “ONE YEAR” on Proposal 4.

As of the date of filing this Proxy Statement, the Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named as proxies in the proxy card to vote on such matters in accordance with their best judgment.

If you receive more than one set of proxy materials, your shares may be registered in more than one name or held in different accounts. Please cast your vote with respect to each set of proxy materials that you receive to ensure that all of your shares are voted.

Even if you plan to attend the Annual Meeting, we recommend that you also submit your vote as early as possible in advance so that your vote will be counted if you later decide not to, or are unable to, attend the Annual Meeting.

If you are the registered shareholder, you may vote your shares in person at the Annual Meeting or by proxy in advance of the Annual Meeting by Internet (at www.proxyvote.com) or, if you requested paper copies of the proxy materials, by completing and mailing a proxy card or by telephone (at 800-690-6903).

If you are the beneficial owner, you may direct your broker, fiduciary or custodian how to vote in advance of the Annual Meeting by following the instructions they provide or, if you want to vote your shares in person at the Annual Meeting, you should contact your bank, broker or other nominee (preferably at least five days before the Annual Meeting) and obtain a “legal proxy”.

If you are the registered shareholder and do not vote in one of the ways described above, your shares will not be voted at the Annual Meeting and will not be counted toward the quorum requirement.

If you are the beneficial owner and do not direct your broker, fiduciary or custodian how to vote your shares, your broker, fiduciary or custodian will only be able to vote your shares with respect to proposals considered to be “routine”. Your broker, fiduciary or custodian is not entitled to vote your shares with respect to “non-routine” proposals, which we refer to as a “broker non-vote”. Whether a proposal is considered routine or non-routine is subject to stock exchange rules and final determination by the stock exchange. Even with respect to routine matters, some brokers are choosing not to exercise discretionary voting authority. As a result, we urge you to direct your broker, fiduciary or custodian how to vote your shares on all proposals to ensure that your vote is counted.

The shares represented by each signed and returned proxy will be voted at the Annual Meeting by the persons named as proxies in the proxy card in accordance with the instructions indicated on the proxy card. However, if you are the registered shareholder and you sign and return your proxy card without giving specific instructions, the persons named as proxies in the proxy card will vote your shares in accordance with the recommendations of the Board. Your shares will be counted toward the quorum requirement.

If you are the beneficial owner and do not direct your broker, fiduciary or custodian how to vote your shares, your broker, fiduciary or custodian will only be able to vote your shares with respect to proposals considered to be “routine”. Your broker, fiduciary or custodian is not entitled to vote your shares with respect to “non-routine” proposals, resulting in a broker non-vote with respect to such proposals.

If you are the registered shareholder, you may revoke your proxy at any time before the final vote at the Annual Meeting in any one of the following ways:

Your last submitted vote is the one that will be counted.

If you are the beneficial owner, you must follow the instructions you receive from your broker, fiduciary or custodian with respect to changing your vote.

The holders of a majority of the shares outstanding must be present in person or represented by proxy at the Annual Meeting to constitute a quorum. A quorum is required to transact business at the Annual Meeting.

Your shares will be counted toward the quorum only if you submit a valid proxy (or a valid proxy is submitted on your behalf by your broker, fiduciary or custodian) or if you attend the Annual Meeting. Abstentions and broker non-votes will be counted toward the quorum requirement. If there is no quorum within 30 minutes of the meeting start time, unless otherwise determined by the Board of Directors, the Annual Meeting will be adjourned to the same day in the next week at the same time and place and, if there is no quorum within 30 minutes of the adjourned meeting start time, the shares present in person or represented by proxy at the adjourned meeting shall constitute a quorum.

Votes will be counted by Broadridge Financial Solutions, the Inspector of Elections appointed for the Annual Meeting.

At the Annual Meeting, directors will be elected by a plurality of the votes cast. This means that the two nominees who receive the highest number of votes cast “FOR” are elected as Class II directors. Broker non-votes, if any, and votes that are withheld will not be counted as votes cast on the matter and will have no effect on the outcome of the election. Shareholders do not have cumulative voting rights for the election of directors.

A simple majority of the votes cast at the Annual Meeting is required to approve Proposals 2, 3 and 4. Broker non-votes, if any, and abstentions will not be counted as votes cast on these matters and will have no effect on the outcome of these matters.

Only shareholders as of the Record Date are entitled to attend the Annual Meeting in person. Attendees should bring the appropriate materials described below in order to be admitted to the meeting.

Natural Persons. If you are a registered shareholder, your name will be on a list, and you will be able to gain entry with a government-issued photo identification, such as a driver’s license, state-issued ID card or passport. If you are the beneficial owner, in order to gain entry you must present a government-issued photo identification and proof of beneficial share ownership as of the Record Date that includes the same name that is on your government-issued photo identification. Acceptable forms of proof of beneficial share ownership include your Notice, a copy of your proxy card or voting instruction form, if you received one, or an account or brokerage statement showing share ownership as of the Record Date.

Entities. If you are a director, officer, trustee or other legal representative of an entity that owns shares of the Company, you must present a government-issued photo identification, evidence that you are authorized to act on behalf of the entity at the Annual Meeting and, if the entity is a beneficial owner, proof of the entity’s beneficial share ownership as of the Record Date.

Non-Shareholders. If you are not a shareholder and are not the representative of an entity that owns shares of the Company, you will be entitled to admission only if you are a proxy holder attending in lieu of a shareholder. To gain entry, you must present a government-issued photo identification and either a valid proxy from a registered shareholder authorizing you to vote the shareholder’s shares or, if you are a proxy holder for a beneficial shareholder, a valid legal proxy from the record holder or the bank, brokerage firm or other nominee that holds shares on behalf of the beneficial shareholder.

The offices of Gibson, Dunn & Crutcher LLP are located at 200 Park Avenue, New York, New York 10166, adjacent to Grand Central Terminal on East 42nd Street and accessible via Metro-North Railroad and various New York City subway lines. All shareholders are directed to the building’s main security desk located on the mezzanine level. Upon presentation of identification and the materials described above, shareholders will be directed to the Gibson, Dunn & Crutcher LLP reception on the 47th floor.

Many cellular phones have built-in digital cameras, and while these phones may be brought into the Annual Meeting, the camera function may not be used at any time. Additional information regarding the rules and procedures for participating in the Annual Meeting will be set forth in our meeting rules of conduct, which will be available to shareholders during the meeting.

We will pay the costs associated with the solicitation of proxies, including the preparation, assembly, printing and mailing of the proxy materials. We may also reimburse brokers, fiduciaries or custodians for the cost of forwarding proxy materials to beneficial owners of shares held in “street name”.

Our employees, officers and directors may solicit proxies in person or via telephone or the Internet. We will not pay additional compensation for any of these services.

We expect to announce preliminary voting results at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K to be filed with the SEC within four business days after the Annual Meeting.

The number of directors constituting the Board is currently set at seven. Pursuant to the terms of our Memorandum and Articles of Association (“MAA”), at the Annual Meeting, the shareholders will vote to elect the two Class II director nominees named in this Proxy Statement to serve until the 2027 Annual General Meeting of Shareholders and until their successors are duly elected and qualified or until their earlier death, resignation or removal. Our Board has nominated Catherine Moukheibir and Dr. Ramnik Xavier for election to our Board. Each of Ms. Moukheibir and Dr. Xavier was initially appointed to the Board in April 2022 in accordance with the Business Combination Agreement. Our director nominees have indicated that they are willing and able to serve as directors. However, if either of them becomes unable or, for good cause, unwilling to serve, proxies may be voted for the election of such other person as shall be designated by our Board, or the Board may decrease the size of the Board.

Our Board is divided into three classes, with members of each class holding office for staggered three-year terms. There are currently two Class II directors, who are up for election at this meeting for a term expiring at the 2027 Annual General Meeting of Shareholders; two Class I directors, whose terms expire at the 2026 Annual General Meeting of Shareholders; and three Class III directors, whose terms expire at the 2025 Annual General Meeting of Shareholders.

The Board recommends a vote “FOR” the election of each of the Class II director nominees set forth above.

Our Audit Committee has selected Baker Tilly US, LLP (“Baker Tilly”) as the Company’s independent registered public accounting firm for the year ending December 31, 2024. In this Proposal 2, we are asking shareholders to vote to ratify this selection. Representatives of Baker Tilly are expected to attend the Annual Meeting. They will have the opportunity to make a statement, if they desire to do so, and are expected to be available to respond to appropriate questions from shareholders.

Shareholder ratification of the selection of Baker Tilly as the Company’s independent auditor is not required by applicable law or our MAA. However, we are seeking shareholder ratification as a matter of good corporate practice. If our shareholders fail to ratify the selection, the committee will reconsider its selection. Even if the selection is ratified, the committee, in its discretion, may direct the selection of a different independent auditor at any time during the year if it determines that such a change would be in the best interests of the Company and our shareholders.

Baker Tilly has served as our independent auditor since June 2022, and previously provided services to MoonLake AG through the Merger Closing. The following table summarizes the audit fees billed and expected to be billed by Baker Tilly for the indicated fiscal years and the fees billed by Baker Tilly for all other services rendered during the indicated fiscal years, including fees for services provided to MoonLake AG prior to the Merger Closing. All services associated with such fees and provided after the Merger Closing were pre-approved by our Audit Committee in accordance with the “Pre-Approval Policies and Procedures” described below.

In addition, in March 2022, MoonLake AG incurred $6,693 (Swiss Francs (“CHF”) 6,180) in audit-related fees for services provided by OBT AG Switzerland, an independent member of Baker Tilly International (“OBT AG”), pertaining to the registration of shares issued from MoonLake AG’s conditional capital with the commercial register of the Canton of Zug, Switzerland. In 2023, MoonLake AG incurred $23,812 (CHF 21,860) in audit fees for services provided by OBT AG pertaining to the audit of the statutory financial statements of MoonLake AG for the period ended December 31, 2022.

Our Audit Committee has adopted procedures requiring the pre-approval of all audit and permissible non-audit services performed by our independent registered public accounting firm. In its pre-approval and review of non-audit service fees, the Audit Committee considers, among other factors, the possible effect of the performance of such services on the auditors’ independence.

These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is reviewed, and if necessary modified, at least annually. The committee may pre-approve certain other audit-related or other non-audit services it believes would not impair the independence of the auditor and are consistent with SEC and Public Company Accounting Oversight Board (“PCAOB”) rules on auditor independence. The committee does not delegate its responsibility to approve services performed by our auditor to any member of management. The committee has delegated authority to the committee chair to pre-approve

any audit or non-audit service to be provided to us by our auditor provided that the fees for such services do not exceed $100,000. Any approval of services by the committee chair pursuant to this delegated authority must be reported to the committee at its next regularly scheduled meeting.

The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2023 with the Company’s management and with Baker Tilly, the Company’s independent registered public accounting firm. The Audit Committee has discussed with Baker Tilly the matters required to be discussed by the applicable standards of the PCAOB and the SEC. The Audit Committee has also received the written disclosures and the letter from Baker Tilly pursuant to applicable PCAOB requirements regarding its communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Baker Tilly its independence. Based on the foregoing, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for filing with the SEC.

This report is provided by the following directors, who serve on the Audit Committee:

The Board recommends a vote “FOR” the ratification, by ordinary resolution, of the selection of Baker Tilly to serve as our independent auditor.

Our Board is asking you to approve, on a non-binding advisory basis, the compensation of our named executive officers, as disclosed in this Proxy Statement. This item, which is provided pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is commonly referred to as a “say-on-pay” resolution.

This say-on-pay proposal gives our shareholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific element of compensation but rather the overall compensation of our named executive officers and our compensation philosophy, policies and practices described in this Proxy Statement. Please read the “Executive Compensation” section and the compensation tables and narrative disclosure that follow for information about our executive compensation program, including details of our 2023 compensation for our named executive officers. Our Compensation Committee believes that these policies and practices are effective in implementing our compensation philosophy and achieving our compensation program goals.

As an advisory vote, the outcome of the vote on this proposal is not binding. However, our Compensation Committee, which is responsible for designing and administering our executive compensation program, will consider the outcome of this vote when making future executive compensation decisions. Unless our Board modifies its policy on the frequency of holding say-on-pay votes, the next say-on-pay vote will occur at our 2025 Annual General Meeting of Shareholders.

The Board recommends a vote “FOR” the approval, on an advisory non-binding basis, of our named executive officers’ compensation.

Pursuant to Section 14A of the Exchange Act, we are providing our shareholders with the opportunity to cast a non-binding advisory vote on the frequency of future advisory votes on executive compensation. Shareholders may specify whether they prefer such votes to occur every one year, two years or three years, or they may abstain from voting. Shareholders are not voting to approve the Board’s recommendation. After careful consideration, our Board recommends that future advisory votes on executive compensation occur every year (annually). We believe that an annual advisory vote on executive compensation is the most appropriate option for us at this time because it will allow our shareholders to provide more frequent and direct input on our compensation policies and practices, and the resulting compensation for our named executive officers. The Board also believes an annual advisory vote on executive compensation promotes corporate transparency and accountability for the Compensation Committee.

This advisory resolution is non-binding on our Board. The Board will consider the voting results in determining the frequency of future advisory votes, and expects to be guided by the alternative that receives the greatest number of votes, even if that alternative does not receive a simple majority vote. Notwithstanding the Board’s recommendation and the outcome of the shareholder vote, the Board may in the future decide to conduct advisory votes on a more or less frequent basis and may vary its practice based on factors such as discussions with shareholders and the adoption of material changes to compensation programs.

This vote on the frequency of future advisory votes on executive compensation must be held at least once every six years, and the next such vote will occur at our 2030 Annual General Meeting of Shareholders.

The Board recommends that future advisory votes on executive compensation be conducted every “ONE YEAR”.

Our business affairs are managed under the direction of our Board. Our Board has adopted a set of Principles of Corporate Governance as a framework for the governance of the Company, which is posted on our website located at ir.moonlaketx.com, under “Corporate Governance”.

Our governance practices reflect the environment in which we operate and are designed to support our mission to advance therapies to address significant unmet needs in inflammatory skin and joint diseases. We are a recently public, pre-revenue single-asset clinical-stage biotechnology company in an evolving industry. We are focused on the development of Sonelokimab, a novel tri-specific IL-17A and IL-17F inhibiting Nanobody, that we exclusively licensed from Merck Healthcare KGaA, Darmstadt, Germany (“MHKDG”) and that has the potential, based on response levels seen in clinical trials, to drive disease modification in dermatology and rheumatology patients. Like other companies in the biotechnology industry, we face extreme share price and volume fluctuations that are often unrelated or disproportionate to our operating performance. With these business environment considerations in mind, the Board put in place our current governance structure to enable the management team to act with deliberation and to focus on delivering long-term value to shareholders and protect minority investors from the interests of potentially short-sighted investors who may seek to act opportunistically and not in the best interests of the Company or shareholders generally. This structure includes the following elements:

Recognizing that the Company’s operating environment continues to evolve and that governance practices should not be static as a matter of course, the Board annually evaluates our governance structure to confirm it remains in the best interests of the Company and shareholders and values input from our shareholders on this topic.

The Nominating Committee is responsible for, among other things, overseeing succession planning for directors and building a qualified board to oversee management’s execution of the Company’s strategy and safeguard the long-term interests of shareholders. In this regard, the committee is charged with developing and recommending Board membership criteria to the Board for approval, evaluating the composition of the Board annually to assess the skills and experience that are currently represented on the Board and the skills and experience that the Board may find valuable in the future, and identifying, evaluating and recommending potential director candidates.

In identifying potential candidates for Board membership, the Nominating Committee considers recommendations from directors, shareholders, management and others, including, from time to time, third-party search firms to assist it in locating qualified candidates. Once potential director candidates are identified, the committee, with the assistance of management, undertakes a vetting process that considers each candidate’s

background, independence and fit with the Board’s priorities. As part of this vetting process, the committee, as well as other members of the Board and the CEO, may conduct interviews with the candidates. If the committee determines that a potential candidate meets the needs of the Board and has the desired qualifications, it recommends the candidate to the full Board for appointment or nomination and to the shareholders for election at the annual general meeting.

In assessing potential candidates for Board membership and in assessing Board composition, the Nominating Committee considers a wide range of factors and generally seeks to balance the following skills, experiences and backgrounds on the Board:

In addition to the above, the Nominating Committee generally believes it is important for all Board members to possess the highest personal and professional ethics, integrity and values, an inquisitive and objective perspective, a sense for priorities and balance, the ability and willingness to devote sufficient time and attention to Board matters, and a willingness to represent the long-term interests of all our shareholders.

In addition to the factors discussed above, the Board and the Nominating Committee actively seek to achieve a diversity of occupational and personal backgrounds on the Board. The Nominating Committee considers a potential director candidate’s ability to contribute to the diversity of personal backgrounds on the Board, including with respect to gender, race, ethnic and national background, geography, age and sexual orientation.

The Nominating Committee assesses its effectiveness in balancing these considerations in connection with its annual evaluation of the composition of the Board. In this regard, our current Board of seven directors includes two directors (28%) who self-identify as female and one director (14%) who self-identifies as racially/ethnically diverse.

In accordance with Nasdaq’s board diversity listing standards, we are disclosing aggregated statistical information about our Board’s self-identified gender and racial characteristics and LGBTQ+ status as voluntarily confirmed to us by each of our directors.

It is the Nominating Committee’s policy to consider written recommendations from shareholders for director candidates. The committee considers candidates recommended by our shareholders in the same manner as a candidate recommended by other sources. Any such recommendations should be submitted to the committee as described under “Shareholder Communications” and should include the same information required under our MAA for nominating a director, as described under “Shareholder Proposals and Director Nominations for Next Year’s Annual General Meeting”.

Mr. Sturge serves as our independent Chairperson while Dr. Santos da Silva serves as our CEO. Our Principles of Corporate Governance provide our Board with the flexibility to combine or separate the positions of Chairperson and CEO. Currently, the Board believes that the roles of Chairperson and CEO should be separate and that the Chairperson should be an independent director as this structure enables our independent Chairperson to oversee corporate governance matters and our CEO to focus on leading the Company’s business. At any time when there is not an independent Chairperson, the Board will designate an independent director to serve as lead director.

The independent directors have the opportunity to meet in executive sessions without management present at every regular Board meeting and at such other times as may be determined by the Chairperson. The purpose of these executive sessions is to encourage and enhance communication among the independent directors.

The Board believes that its programs for overseeing risk, as described under “Board Risk Oversight”, would be effective under a variety of leadership frameworks. Accordingly, the Board’s risk oversight function did not significantly impact its selection of the current leadership structure.

Nasdaq listing rules require a majority of a listed company’s board of directors to be comprised of independent directors who, in the opinion of the board of directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Subject to specified exceptions, each member of a listed company’s audit, compensation and nominating committees must be independent, and audit and compensation committee members must satisfy additional independence criteria under the Exchange Act.

Our Board undertook a review of its composition and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including the beneficial ownership of our voting ordinary shares by each non-employee director, our Board has determined that Messrs. Sturge and Loy, Drs. Lassen, Phillips, and Xavier, and Ms. Moukheibir qualify as “independent directors” as defined by the Nasdaq listing rules. Dr. Santos da Silva is not deemed to be independent under Nasdaq listing rules by virtue of his employment with the Company.

Our Board also determined that each of the directors currently serving on the Audit Committee and the Compensation Committee satisfy the additional independence criteria applicable to directors on such committees under Nasdaq listing rules and the rules and regulations established by the SEC.

Our Board has a separately designated Audit Committee, Compensation Committee and Nominating Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of these committees is empowered to retain outside advisors as it deems appropriate, regularly reports its activities to the full Board and has a written charter, which is posted on our website located at ir.moonlaketx.com, under “Corporate Governance”.

Audit Committee. The primary responsibilities of our Audit Committee are to oversee the accounting and financial reporting processes of the Company, including the audits of the Company’s financial statements, the integrity of the financial statements and the annual review of the performance, effectiveness and independence of the outside auditor. This includes reviewing the financial information provided to shareholders and others and the adequacy and effectiveness of the Company’s internal controls. The committee also makes recommendations to the Board as to whether financial statements should be included in the Company’s Annual Report on Form 10-K.

Ms. Moukheibir qualifies as an “audit committee financial expert”, as that term is defined in the rules and regulations established by the SEC, and all members of the Audit Committee are “financially literate” under Nasdaq listing rules.

Compensation Committee. The primary responsibilities of our Compensation Committee are to periodically review and approve the compensation and other benefits for our senior officers and directors. This includes reviewing and approving corporate goals and objectives relevant to the compensation of our senior officers, evaluating the performance of these officers in light of the goals and objectives and setting the officers’ compensation based on those evaluations. The committee also administers and makes recommendations to the Board regarding equity incentive plans that are subject to the Board’s approval and approves the grant of equity awards under the plans.

The Compensation Committee may delegate its authority to one or more subcommittees. The committee may also delegate authority to review and approve the compensation of our employees to certain of our executive officers. Even where the committee does not delegate authority, our executive officers will typically make recommendations to the committee regarding compensation to be paid to our employees and the size of equity awards under our equity incentive plans, but will not be present during voting or deliberations on their own compensation. The committee has the authority to engage outside advisors, such as compensation consultants, to assist it in carrying out its responsibilities. The committee engaged Deloitte AG (“Deloitte”) in 2023 to provide advice regarding the amount and form of executive and director compensation. The committee assessed Deloitte’s independence and has determined that (1) Deloitte satisfies applicable independence criteria, and (2) Deloitte’s work with the Company does not raise any conflicts of interest, in each case under applicable Nasdaq listing rules and the rules and regulations established by the SEC.

Nominating Committee. The primary responsibilities of our Nominating Committee are to engage in succession planning for the Board, develop and recommend to the Board criteria for identifying and evaluating qualified director candidates and make recommendations to the Board regarding candidates for election or reelection to the Board at each annual shareholders’ meeting. In addition, the committee is responsible for overseeing our corporate governance practices and making recommendations to the Board concerning corporate governance matters. The committee is also responsible for making recommendations to the Board concerning the structure, composition and functioning of the Board and its committees.

We believe that risk management is an important part of establishing and executing on the Company’s business strategy. Our Board, as a whole and at the committee level, focuses its oversight on the most significant risks facing the Company and on the Company’s processes to identify, prioritize, assess, manage and mitigate those risks. The committees oversee specific risks within their purview, as follows:

Our Board and its committees receive regular reports from members of the Company’s senior management on areas of material risk to the Company, including strategic, operational, financial, legal and regulatory risks. While our Board has an oversight role, management is principally tasked with direct responsibility for assessing and managing risks, including implementing processes and controls to mitigate their effects on the Company.

The Board met nine times during the year ended December 31, 2023. Each member of the Board attended at least 75% of the aggregate number of meetings of the Board and the committees on which he or she served during the period in which he or she was on the Board or committee.

Directors are encouraged to attend the annual general meeting of shareholders. All of our directors then serving on the Board attended our 2023 Annual General Meeting of Shareholders.

Shareholders and other interested parties may communicate with our Board or a particular director by sending a letter addressed to the Board or a particular director to our Corporate Secretary at the address set forth on the first page of this Proxy Statement. These communications will be compiled and reviewed by our Corporate Secretary, who will determine whether the communication is appropriate for presentation to the Board or the particular director. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications).

To enable the Company to speak with a single voice, as a general matter, senior management serves as the primary spokesperson for the Company and is responsible for communicating with various constituencies, including shareholders, on behalf of the Company. Directors may participate in discussions with shareholders and other constituencies on issues where Board-level involvement is appropriate. In addition, the Board is kept informed by Company management of the Company’s shareholder engagement efforts.

The Board has adopted a Code of Business Conduct and Ethics (the “Conduct and Ethics Code”) that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer. Among other things, the Conduct and Ethics Code establishes certain guidelines and

principles relating to (i) compliance with laws and regulations, (ii) conflicts of interest, (iii) corporate opportunities, (iv) gifts, (v) confidentiality, (vi) protection and use of Company assets, (vii) record keeping, (viii) environmental, health and safety, (ix) discrimination and harassment, (x) prohibition against payments to government personnel and (xi) insider information and securities trading, as well as establishes internal reporting and compliance procedures.

A copy of the Conduct and Ethics Code is available on our website at ir.moonlaketx.com, under “Corporate Governance”. We intend to disclose future amendments to certain provisions of the Conduct and Ethics Code, and waivers of the Conduct and Ethics Code granted to executive officers and directors, on our website within four business days following the date of the amendment or waiver. Our Board is responsible for applying and interpreting the code in situations where questions are presented to it.

We have a policy that prohibits our directors, officers, employees, consultants and contractors from engaging in (a) short-term trading; (b) short sales; (c) transactions involving publicly traded options or other derivatives, such as trading in puts or calls with respect to Company securities; and (d) hedging transactions.

None of the members of our Compensation Committee has at any time during the prior three years been one of our officers or employees. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board or compensation committee of any entity that has one or more executive officers serving on our Board or Compensation Committee.

Our Board has adopted a director compensation program pursuant to which members of our Board who are not employees or officers of our Company or our affiliates receive the following cash retainers, payable quarterly in advance:

In addition, in 2023, each of our non-employee directors other than Dr. Lassen received a grant of 11,297 share options on June 8, 2023 under the MoonLake Immunotherapeutics 2022 Equity Incentive Plan (the “Incentive Plan”) that vest in full on the earlier of the one-year anniversary of the date of grant and the next annual general meeting of shareholders, subject to continued service through such date. Dr. Lassen waived her right to receive such grant.

Members of our Board are also eligible to receive reimbursement for reasonable travel and miscellaneous expenses incurred in attending meetings and activities of our Board and its committees. Additionally, directors who are also members of the board of directors of MoonLake AG (Messrs. Sturge and Loy and Dr. Phillips) are reimbursed for business expenses reasonably incurred in connection with such services.

The following table summarizes information concerning the compensation awarded to, earned by and paid to the non-employee directors for services rendered to the Company for the year ended December 31, 2023.

Biographical and other information regarding our executive officers is set forth below. There are no family relationships among any of our directors or executive officers.

In accordance with SEC transition rules, in this Proxy Statement, we are continuing to provide executive compensation disclosures under the SEC’s scaled disclosure framework. Accordingly, our reporting obligations with respect to our “named executive officers” extend only to the individuals who served as the principal executive officer and the next two most highly compensated executive officers as of the end of the prior fiscal year, as well as up to two additional individuals for whom disclosure would have been provided based on their compensation levels but for the fact that the individual was not serving as an executive officer at the end of the prior fiscal year.

The named executive officers (“NEOs”) for 2023 are Dr. Santos da Silva (Chief Executive Officer), Mr. Bodenstedt (Chief Financial Officer) and Dr. Reich (Chief Scientific Officer).

The following table summarizes information concerning the compensation awarded to, earned by and paid to the named executive officers for services rendered to us for the years ended December 31, 2023 and 2022.

MoonLake AG entered into employment agreements with each of Drs. Santos da Silva and Reich on April 30, 2021, as subsequently amended on September 21, 2021 for Dr. Santos da Silva and on November 8, 2021 for Dr. Reich, and with Mr. Bodenstedt on May 10, 2021, as subsequently amended on June 22, 2021 (the “Executive Employment Agreements”, and each an “Executive Employment Agreement”). The Executive Employment Agreements are based on the same general form, and the material terms of the agreement are summarized below. The Executive Employment Agreements remained in place upon the Merger Closing. The Executive Employment Agreements are governed by Swiss law.

The terms of the Executive Employment Agreements with each of Dr. Santos da Silva and Mr. Bodenstedt commenced on July 1, 2021. The term of the Executive Employment Agreement with Dr. Reich commenced on May 17, 2021. The initial terms of these agreements ran through May 1, 2023, except for Mr. Bodenstedt’s agreement, which provides for an indefinite term. Under the agreements with Drs. Santos da Silva and Reich, either the executive or MoonLake AG could have terminated the Executive Employment Agreement at the end of such initial term by providing six months’ notice. Since no such notice was provided under such agreements, the terms of the Executive Employment Agreements were extended for an indefinite period, and employment will be terminable by either party by providing six months’ notice. The Executive Employment Agreement with Mr. Bodenstedt provides for termination of his employment by either party by providing six months’ notice beginning on August 31, 2022.

The Executive Employment Agreements provide for annual base salaries and target bonuses, which were subsequently increased. Effective July 1, 2023, annual base salaries were increased as follows: (i) for Dr. Santos da Silva from CHF 450,000 to CHF 600,000, (ii) for Dr. Reich from CHF 450,000 to CHF 600,000 and (iii) for Mr. Bodenstedt from CHF 325,000 to CHF 475,000. Each of Drs. Santos da Silva and Reich are eligible to receive a target bonus equal to 55% of his annual base salary. Payment of such annual bonus is based on the achievement of reasonable financial and business objectives mutually agreed upon by the officer and MoonLake AG. The performance objectives for each of Drs. Santos da Silva and Reich for fiscal year 2023 were to (i) build our Company and its profile with key stakeholders; (ii) deliver the SLK global Phase 2 program in HS and PsA; and (iii) achieve cash runway for the completion of the SLK global Phase 2 program in HS and PsA, as well as cash runway through the end of the second quarter of 2024. Each of Drs. Santos da Silva and Reich earned a payment of CHF 495,000 with respect to the achievement of their respective performance objectives for fiscal year 2023, reflecting a 150% achievement of their targets.

In the event of a termination of employment by the officer, he will be entitled to receive a prorated payment of his annual bonus based on the level of achievement through the date of termination. In the event of a termination of employment by MoonLake AG, the board of directors of MoonLake AG will determine whether a bonus will be paid and the amount to be paid.

Mr. Bodenstedt is eligible to receive a target bonus of 50% of his annual base salary. The award of such a bonus is entirely within MoonLake AG’s discretion and depends on Mr. Bodenstedt’s individual performance, achievement of pre-determined milestones and/or meeting of pre-defined criteria. Mr. Bodenstedt is not eligible for a bonus if at the time of the payment of the bonus, his employment is pending termination. The performance objectives for Mr. Bodenstedt for fiscal year 2023 were to (i) build our Company and its profile with key stakeholders; (ii) deliver the SLK global Phase 2 program in HS and PsA; and (iii) achieve cash runway for the completion of the SLK global Phase 2 program in HS and PsA, as well as cash runway through the end of the second quarter of 2024. Mr. Bodenstedt earned a payment of CHF 356,250 with respect to the achievement of his performance objectives for fiscal year 2023, reflecting a 150% achievement of his target.

Drs. Santos da Silva and Reich were each eligible until June 30, 2023 to receive an additional payment under their respective Executive Employment Agreements. In the event the officer was subject to social security laws outside of Switzerland as a result of his place of residence, then he was eligible to receive additional payments from MoonLake AG. In the event the total hypothetical Swiss social security contributions that MoonLake AG would have been required to pay with respect to the officer were greater than the minimum mandatory employer contributions for the same insurance in the officer’s country of residence, then such officer was entitled to receive the difference between such amounts. In 2023, Dr. Reich met this condition and received additional payments for the period from January to June 2023 of CHF 27,156.

Each officer is eligible to receive retirement, survivors and disability insurance, as well as accident insurance, according to Swiss law requirements. In addition, MoonLake AG has taken out daily sickness benefits insurance, and is contributing 50% of the premiums with the other 50% contributed by the employees, for Dr. Santos da Silva and Mr. Bodenstedt, providing salary continuation payments in the amount of 80% of the insured salary, which is capped at CHF 300,000, after a 30 days waiting period for a maximum of 730 days. Due to being subject to social security outside of Switzerland, Dr. Reich is not eligible for the selected insurance plan, and instead until June 30, 2023 received the theoretical

employer contribution as an additional monthly payment as part of his regular salary (included under “Additional Cash Payments”). In addition, the officer will be reimbursed for justified expenses incurred in the course of his work for MoonLake AG due to travel and other expenses. The named executive officers also received housing allowances during fiscal year 2023.

Each of the Executive Employment Agreements includes an intellectual property assignment agreement, as well as a perpetual covenant prohibiting the officer from utilizing and disclosing confidential information, a non-competition covenant, an employee non-solicitation covenant and a customer non-solicitation covenant. For Drs. Santos da Silva and Reich, each of these covenants is in effect during the employment term and for a period of six months following a termination of employment. For Mr. Bodenstedt, the non-competition covenant is in effect during the employment term and for a period of twelve months following a termination of employment, and the employee non-solicitation covenant and the customer non-solicitation covenant are in effect during the employment term and for a period of eighteen months following a termination of employment. Such non-compete and non-solicitation covenants are referred to herein as the “post-termination restrictive covenants”.

If either Drs. Santos da Silva or Reich terminates his employment, then he is entitled to receive monthly compensation during the duration of such post-termination restrictive covenants in an amount of his last monthly fixed salary (gross). If he terminates his employment without just cause, then MoonLake AG may waive its right to enforce such post-termination restrictive covenants and thereby cease making such post-termination payments to the officer.

If MoonLake AG terminates the officer’s employment, then he is entitled to receive monthly compensation during the duration of such post-termination restrictive covenants in an amount of his monthly fixed salary (gross) plus an amount equal to one-twelfth of his annual target bonus. The officer would be entitled to receive such payments even if MoonLake AG waives its right to enforce the post-termination restrictive covenants.

In the event an officer, including Mr. Bodenstedt, breaches his obligations under the post-termination restrictive covenants, he would owe a contractual penalty to MoonLake AG of CHF 100,000 for each individual breach. MoonLake AG would also be entitled to additional damages and to seek specific performance as a remedy. In addition, the officer would forfeit any remaining amounts that would have otherwise been payable during the duration of the post-termination restrictive covenants, and the officer would be required to repay any payments he previously received during the post-termination restrictive covenant period.

If the post-termination restrictive covenants are unenforceable, lapse or are not effective under applicable law, then Drs. Santos da Silva and Reich will instead receive a severance payment equal to 50% of his then current annual gross salary (plus 50% of his annual target bonus in the event MoonLake AG is the party that terminates employment) payable ratably over the six-month post-termination period.

The following table sets forth information regarding equity awards held by our named executive officers as of December 31, 2023:

MoonLake AG operates a defined benefit pension plan (the “MoonLake AG Swiss Plan”) in accordance with local Swiss regulations and practices. It covers all of MoonLake AG’s employees that are subject to Swiss social security, including the named executive officers (other than Dr. Reich) and provides benefits in the event of death, disability, or retirement. The MoonLake AG Swiss Plan complies with Swiss tax requirements applicable to broad-based pension plans. Normal retirement age under the MoonLake AG Swiss Plan is 65, for men, and 64, for women. All benefits are immediately vested.

Under the MoonLake AG Swiss Plan, 15% of pensionable salary is contributed as retirement credit with additional contributions for death and disability benefits. MoonLake AG makes 50% of the contributions, and the covered employee makes 50% of the contributions. For 2023, participants received an interest rate of return of 1% on retirement assets under the Swiss Federal Law on Occupational Retirement, Survivors’ and Disability Pension Plans (BVG) and 1% on extra-mandatory retirement assets. Pensionable salary under the MoonLake AG Swiss Plan is the annual base salary.

Annual benefits under the MoonLake AG Swiss Plan are calculated at a named executive officer’s retirement date and are equal to a percentage of the named executive officer’s account balance specified in the MoonLake AG Swiss Plan based on his age and retirement year. Under Swiss pension law, participants who were covered by the pension plan of another employer are required to transfer the termination benefit of that pension plan into the MoonLake AG Swiss Plan. Participants are permitted to withdraw part of the termination benefit, or pledge the termination benefit, for home ownership.

MoonLake AG makes contributions to a retirement arrangement governed by German law on behalf of Dr. Reich. Dr. Reich’s retirement arrangement program is a defined contribution type structure whereby MoonLake AG makes contributions to a German government regulated pension plan in an amount equal to 9.3% of earned income up to a maximum total earned income, including income derived from his employment at MoonLake AG and other pensionable income, of Euro (“EUR”) 7,300 per month.

None of the named executive officers received any equity awards in 2023.

Shares of MoonLake AG purchased by the participant under the ESPP are unvested as of the date of grant and are subject to MoonLake AG’s repurchase right under the ESPP until the grant fully vests. The vesting schedule set forth in the ESPP provides for vesting in equal, annual installments of 25% until the grant fully vests on the fourth anniversary of the date of grant, unless provided otherwise in an individual allocation agreement. The vesting schedules applicable to the NEOs are set forth in the footnotes to the Outstanding Equity Awards at 2023 Fiscal Year End table above. Such vesting is subject to the participant’s continued employment through each applicable vesting date. Unvested shares will be automatically vested in full upon the occurrence of a “change of control” (as defined in the ESPP).

Until a grant of shares under the ESPP fully vests, MoonLake AG may repurchase shares granted to a participant at a repurchase price equal to the nominal value of the shares. In the event the participant’s termination of employment is a “good leaver” (as defined in the ESPP) termination, MoonLake AG may repurchase all or a prorated portion of the unvested shares on the date the termination becomes effective. In the event the participant’s termination of employment is a “bad leaver” (as defined in the ESPP) termination, MoonLake AG may repurchase all or a prorated portion of the shares (both vested and unvested). In addition, MoonLake AG has a right of first refusal with respect to vested shares granted to a participant under the ESPP.

We have adopted an Incentive Compensation Clawback Policy, which is intended to comply with the requirements of Nasdaq Listing Standard 5608 implementing Rule 10D-1 under the Exchange Act. In the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to material

non-compliance with any financial reporting requirement under the federal securities laws, the Company will recover, on a reasonably prompt basis, the excess incentive-based compensation received by any covered executive during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive “compensation actually paid” and certain financial performance of the Company.

While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular year. In accordance with SEC rules, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

The following table sets forth information known to us regarding the beneficial ownership of our voting ordinary shares as of March 15, 2024, by:

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including any shares that the individual has the right to acquire within 60 days after the date of this table. Unless otherwise indicated, to our knowledge and subject to community property rules, we believe that all persons named in the table below have sole voting and sole investment power with respect to the voting securities beneficially owned by them.

Pursuant to our MAA, each Class A Ordinary Share entitles the holders thereof to one vote per share and such economic rights as are set forth in the MAA, and each Class C Ordinary Share entitles the holders thereof to one vote per share, but carries no economic rights.

Prior to the Merger Closing, Helix utilized office space at 200 Clarendon Street, 52nd Floor, Boston, Massachusetts 02116 from the Sponsor as its executive offices. Helix paid the Sponsor $10,000 per month for office space, utilities, administrative services and remote support services provided to members of its management team. Upon the Merger Closing, Helix ceased paying these monthly fees.

No compensation of any kind, including finder’s and consulting fees, was paid by Helix to the Sponsor, Helix’s officers and directors, or any of Helix’s or their respective affiliates, for services rendered prior to or in connection with the Merger Closing. However, these individuals were reimbursed for any out-of-pocket expenses incurred in connection with activities on Helix’s behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations. Helix’s audit committee reviewed on a quarterly basis all payments that were made to the Sponsor, Helix’s officers and directors, or Helix’s or their affiliates.

On February 20, 2022, Helix, MoonLake AG, Cormorant Private Healthcare Fund IV, L.P., an affiliate of the Sponsor and certain of Helix’s officers and directors (the “Cormorant Lender”), and BVF, BVF2 and Trading Fund OS (the “BVF Shareholders”) entered into the Convertible Loan Agreement, pursuant to which the Cormorant Lender loaned to MoonLake AG an aggregate principal amount of $15,000,000 to finance MoonLake AG’s general corporate purposes until the Merger Closing, including product and technology development, operations, sales and marketing, management expenses and salaries. The loan was interest-free and unsecured. The loan was repaid in full at the Merger Closing.

On April 5, 2022, MoonLake AG, Helix and the ML Parties entered into a Restated and Amended Shareholders’ Agreement (the “A&R Shareholders’ Agreement”). With the intent to approximate the rights, obligations and restrictions that an ML Party would enjoy if it were a holder of Class A Ordinary Shares, the A&R Shareholders’ Agreement: (i) imposes certain transfer and other restrictions on the ML Parties, (ii) provides for the waiver of certain statutory rights and (iii) establishes certain mechanics whereby MoonLake and each of the ML Parties are able to effect the conversion of MoonLake AG Common Shares and Class C Ordinary Shares into a number of Class A Ordinary Shares equal to an exchange ratio of 1 MoonLake AG Common Share for 33.638698 Class A Ordinary Shares.

In April 2021, MoonLake AG entered into a license agreement and related side letter with MHKDG, a holder of more than 5% of our voting ordinary shares at the time, pursuant to which MoonLake AG acquired the right and

license under MHKDG’s patents, licenses, materials and exclusive know-how to develop, manufacture, use, sell, offer for sale, export and import and otherwise commercialize on a world-wide basis (the “License Agreement”). The aggregate purchase price consisted of an upfront cash payment in the amount of $25 million and a transfer of shares in MoonLake AG representing a 9.9% ownership stake in MoonLake AG following the transaction. Subject to the terms of the license agreement, milestone cash payments of up to EUR 307.1 million ($339.5 million using a December 31, 2023 exchange rate) are potentially payable, of which EUR 7.5 million ($8.0 million using the then applicable exchange rate of 1.073 USD per EUR) has been recognized as expensed as of December 31, 2023. Future milestones will become payable upon regulatory filing acceptances in the US, in the European Union and Japan, first commercial sales in these geographies, and meeting certain annual thresholds in global net sales. In addition, the License Agreement requires us to pay royalties within the range of low to mid-teen percent of net sales.

The loan was interest-free and was repaid in full on April 11, 2022.

On June 27, 2023, the Company entered into an underwriting agreement with Leerink Partners LLC and Guggenheim Securities LLC, as the representatives of the underwriters named therein, relating to the issuance and sale of an aggregate of 9,200,000 Class A Ordinary Shares at a public offering price of $50.00 per share (the “Offering”), including shares issued upon exercise in full by the underwriters of their option to purchase additional shares, for aggregate gross proceeds of $460.0 million, before deducting underwriting discounts and commissions and offering expenses.

We have adopted a written related person transaction policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of our policy, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we and any related person (as defined above) are, were or will be participants in which the amount involved exceeds the lesser of $120,000 or one percent of the average of our total assets at year-end for the last two completed fiscal years. Transactions involving compensation for services provided to us as an employee or director, among other limited exceptions, are deemed to have standing pre-approval by the Audit Committee but may be specifically reviewed if appropriate in light of the facts and circumstances.

Under the policy, if a transaction has been identified as a related person transaction, our Audit Committee must review the material facts and either approve or disapprove of the entry into the transaction. If advance approval of the transaction is not feasible, then the transaction will be considered and, if the Audit Committee determines it to be appropriate, ratified at the next regularly scheduled meeting. In addition, under our Code of Business Conduct and Ethics, our employees and directors have an affirmative responsibility to avoid activities that create or give the appearance of a conflict of interest, and directors and executive officers must consult and seek prior approval of potential conflicts of interest from the Audit Committee. In considering related party transactions, our Audit Committee will take into account the relevant available facts and circumstances including, but not limited to:

Except for the Offering, which was reviewed in accordance with the foregoing policies and procedures, the related party transactions described above were consummated prior to our adoption of the formal, written policy described above, and, accordingly, the foregoing policies and procedures were not followed with respect to these transactions. However, we believe that the terms obtained or consideration that we paid or received, as applicable, in connection with these transactions were comparable to terms available or the amounts that would be paid or received, as applicable, in arm’s-length transactions at such time.

Pursuant to Rule 14a-8 of the Exchange Act, shareholders who wish to submit proposals for inclusion in the proxy statement for the 2025 Annual General Meeting of Shareholders must send such proposals to our Corporate Secretary at the address set forth on the first page of this Proxy Statement. Such proposals must be received by us as of the close of business (6:00 p.m. Central European Time) on December 25, 2024 and must comply with Rule 14a-8 of the Exchange Act. The submission of a shareholder proposal does not guarantee that it will be included in the proxy statement.

As set forth in our MAA, if a shareholder intends to make a nomination for director election or present a proposal for other business (other than pursuant to Rule 14a-8 of the Exchange Act) at the 2025 Annual General Meeting of Shareholders, the shareholder’s notice must be received by our Corporate Secretary at the address set forth on the first page of this Proxy Statement no earlier than the 120th day and no later than the 90th day before the anniversary of the last annual general meeting; provided, however, that if the date of the annual general meeting is more than 30 days before or after such anniversary date, the shareholder’s notice must be delivered not later than the later of (x) the close of business on the 90th day prior to such annual general meeting and (y) if the first public announcement of the date of such meeting is less than 100 days prior to the meeting, 10 days following the date of the first public announcement of the meeting date. Therefore, unless the 2025 Annual General Meeting of Shareholders is more than 30 days before or after the anniversary of the Annual Meeting, notice of proposed nominations or proposals (other than pursuant to Rule 14a 8 of the Exchange Act) must be received by our Corporate Secretary no earlier than February 5, 2025 and no later than the close of business (6:00 p.m. Central European Time) on March 7, 2025 Any such director nomination or shareholder proposal must be a proper matter for shareholder action and must comply with the terms and conditions set forth in our MAA. If a shareholder fails to meet these deadlines or fails to satisfy the requirements of Rule 14a-4 of the Exchange Act, we may exercise discretionary voting authority under proxies we solicit to vote on any such proposal as we determine appropriate. In addition to satisfying the deadlines in the advance notice provisions of our MAA, a shareholder who intends to solicit proxies in support of nominees submitted under these advance notice provisions for the 2025 Annual General Meeting of Shareholders must provide the notice required under Rule 14a-19 of the Exchange Act to our Corporate Secretary in writing not later than the close of business (6:00 p.m. Central European Time) on April 7, 2025. We reserve the right to reject, rule out of order or take other appropriate action with respect to any nomination or proposal that does not comply with these and other applicable requirements.

A number of brokerage firms have adopted a procedure approved by the SEC called “householding”. Under this procedure, certain shareholders who have the same address and do not participate in electronic delivery of proxy materials will receive only one copy of the proxy materials, including this Proxy Statement, the Notice and our Annual Report on Form 10-K for the year ended December 31, 2023, until such time as one or more of these shareholders notifies us that they wish to receive individual copies. This procedure helps to reduce duplicate mailings and save printing costs and postage fees, as well as natural resources. If you received a “householding” mailing this year and would like to have additional copies of the proxy materials mailed to you, please send a written request to our Corporate Secretary at the address set forth on the first page of this Proxy Statement, or call 41-41-510-8022, and we will promptly deliver the proxy materials to you. Please contact your broker if you received multiple copies of the proxy materials and would prefer to receive a single copy in the future, or if you would like to opt out of “householding” for future mailings.

We will provide, free of charge, a copy of our Annual Report on Form 10-K for the year ended December 31, 2023, including exhibits, on the written or oral request of any shareholder of the Company. Please send a written request to our Corporate Secretary at the address set forth on the first page of this Proxy Statement, or call the number above.
