Beneficial Owners must enclose with their Attendance Notice (i) proof of their beneficial ownership of the relevant underlying shares in the Company’s capital, such as a recent account statement, and (ii) a signed proxy authorizing them to act from the relevant shareholder who is registered in either of the Registers as the holder of those underlying shares on the Record Date.

If you are a Beneficial Owner with Ordinary Shares held in street name, you will receive instructions on how to vote from your bank, broker, dealer or other financial institution. You must follow their instructions in order for your shares to be voted. Telephone and Internet voting also may be offered to shareholders owning Ordinary Shares through certain financial institutions. If your Ordinary Shares are held in street name and you would like to vote your shares in person at the Annual General Meeting, you should contact your bank, broker, dealer or other financial institution to obtain a legal proxy and deliver a valid Attendance Notice.

It is important that your shares be represented at the Annual General Meeting regardless of whether you plan to attend in person.

Telephone and Internet voting facilities will be available 24 hours a day and will close at the Cut-off Time.

Voting your shares or submitting your proxy, as applicable, will be important for the presence of a quorum at the Annual General Meeting and will save us the expense of further solicitation. Submitting a proxy will not prevent you from voting your shares at the Annual General Meeting if you desire to do so, as your proxy is revocable at your option. Your vote is important regardless of the number of shares in the Company’s capital that you own. If you do not plan to attend the Annual General Meeting and if you are a Person with Meeting Rights, please submit your proxy instructions via the Internet, telephone or by mail, or, if you are a Beneficial Owner, please submit the voting instruction form you receive from your broker or nominee as soon as possible so your shares can be voted at the Annual General Meeting.

Who is soliciting my vote?

Why did I receive these proxy materials?

You have received these proxy materials because the Board of Directors is soliciting your proxy for the Annual General Meeting. This proxy statement includes information that we are required to provide to you under the rules of the U.S. Securities and Exchange Commission (the “SEC”) and that is designed to assist you in voting your shares. Under the rules adopted by the SEC, we have elected to mail you our proxy materials. All shareholders will also have the ability to access the proxy materials at www.proxyvote.com.

We intend to mail the proxy statement on or about       , 2025 to all shareholders of record entitled to vote at the Annual General Meeting.

How do I attend the Annual General Meeting?

The Annual General Meeting will start at 5:00 p.m. CEST on June 4, 2025 at the offices of NautaDutilh N.V., Beethovenstraat 400, 1082 PR Amsterdam, the Netherlands.

The record date under Dutch law (registratiedatum) for the Annual General Meeting is May 7, 2025 (the “Record Date”). Those who are shareholders of the Company, or who otherwise have voting rights and/or meeting rights with respect to shares in the Company’s capital, at the close of business on the Record Date and who are recorded as such in the Company’s shareholders’ register or in the register maintained by the Company’s U.S. transfer agent (the “Registers”) may attend, and, if relevant, vote at the Annual General Meeting (“Persons with Meeting Rights”), irrespective of changes to their shareholdings or rights after the Record Date.

Persons with Meeting Rights and shareholders who beneficially own shares in the Company’s capital in an account at a bank, broker, dealer or other financial institution (the “Beneficial Owners”) on the Record Date who wish to attend the Annual General Meeting, in person or represented by proxy, must notify the Company in writing of their identity and intention to attend the Annual General Meeting (an “Attendance Notice”) no later than 11:59 p.m. Eastern Time on June 2, 2025 (5:59 a.m. CEST on June 3, 2025) (the “Cut-off Time”).

Any Attendance Notice, proof of beneficial ownership or signed proxy received after the Cut-off Time may not be accepted. Persons with Meeting Rights, Beneficial Owners and proxyholders who have not complied with the procedures described above may be refused entry to the Annual General Meeting.

What am I voting on?

There are nine matters scheduled for a vote:

2

Who can vote at the Annual General Meeting?

Only shareholders of record at the close of business on the Record Date will be entitled to vote at the Annual General Meeting.

Shareholders of Record: Persons with Meeting Rights may vote at the Annual General Meeting or by submitting a proxy before the Cut-Off Time.

Beneficial Owners: If on the Record Date, your Ordinary Shares were not registered in your name in the Registers, but instead held through a bank, broker, dealer or other financial institution, then you are a Beneficial Owner with shares held in “street name” and the proxy statement is being forwarded to you by that institution. The institution holding your shares is deemed to be the Person with Meeting Rights for purposes of the Annual General Meeting. In order to vote, Beneficial Owners must have the institution that holds their shares issue a proxy to them which confirms they are authorized to take part in and vote at the Annual General Meeting. Beneficial Owners are also entitled to direct their bank, broker, dealer or other financial institution regarding how to vote the shares in the account of the Beneficial Owner by following the voting instructions provided by such financial institution.

See the question titled “How do I Vote?” for a description of how you can vote the Ordinary Shares held of record in your name or which you beneficially own.

How does the Board of Directors recommend that I vote?

The Board of Directors unanimously recommends that you:

Will any other business be conducted at the Annual General Meeting?

There are no other matters that have been properly brought before the Annual General Meeting.

How do I vote?

With respect to proposals 1, 2, 3, 4, 5, 6, 7 and 8, you may vote “For” or “Against,” or you may abstain from voting. With respect to proposal 9, you may vote “1 YEAR,” “2 YEARS” or “3 YEARS,” or you may abstain from voting.

We encourage shareholders to submit their proxy before the Cut-off Time in order to vote their shares, regardless of whether they plan to attend the Annual General Meeting and vote in person.

Persons with Meeting Rights – If you are a Person with Meeting Rights, your Ordinary Shares are registered in your name you may vote by attending the meeting, by telephone, over the internet or by mail by following the

3

directions included in the proxy card that you may request or that we may deliver to you. Your vote must be received before the Cut-off Time in order to be counted. Instructions on how you may vote are as follows:

Telephone and Internet voting facilities will be available 24 hours a day and will close at the Cut-off Time.

Beneficial Owners—If you are a Beneficial Owner with Ordinary Shares held in street name, you will receive instructions on how to vote from your bank, broker, dealer or other financial institution. You must follow their instructions in order for your shares to be voted. Telephone and Internet voting also may be offered to shareholders owning Ordinary Shares through certain financial institutions. If your Ordinary Shares are held in street name and you would like to vote your shares in person at the Annual General Meeting, you should contact your bank, broker, dealer or other financial institution to obtain a legal proxy and deliver a valid Attendance Notice.

How many votes do I have?

On each matter to be voted upon, you have one vote for each Ordinary Share you own as of the Record Date.

If I am a Person with Meeting Rights and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?

If you are a Person with Meeting Rights and do not vote by submitting your proxy card, by telephone, by mail or e-mail, through the internet or by voting at the Annual General Meeting, your Ordinary Shares will not be voted. Such failure to vote will have no effect on the proposals, assuming a quorum is present, and will not count for purposes of determining whether a quorum is present or for the purpose of determining the number of votes cast.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your Ordinary Shares will be voted in accordance with the recommendations of the Board of Directors and you will be deemed to have instructed your Ordinary Shares to be voted accordingly.

If I am a Beneficial Owner of Ordinary Shares held in street name and I do not provide my broker or bank with voting instructions, what happens?

If you are a Beneficial Owner and you do not instruct your bank, broker, dealer or other financial institution how to vote your Ordinary Shares, your bank, broker, dealer or other financial institution may still be able to vote your shares in its discretion on certain “routine” proposals. Brokers, banks and other securities intermediaries are

4

subject to certain rules and may use their discretion to vote your “uninstructed” Ordinary Shares with respect to matters considered to be “routine,” in which case your shares will count for purposes of determining whether a quorum is present, but not with respect to “non-routine” matters. The Ordinary Shares not voted are referred to as “broker non-votes.” Proposals 2, 5, 6, 8 and 9 are considered to be “non-routine,” meaning that your bank, broker, dealer or other financial institution may not vote your shares on these proposals in the absence of your voting instructions. However, Proposals 1, 3, 4 and 7 are considered to be “routine” matters, meaning that if you do not return voting instructions to your bank, broker, dealer or other financial institution by its deadline, your Ordinary Shares may be voted by your bank, broker, dealer or other financial institution in its discretion on these proposals. Accordingly, if you own Ordinary Shares through a nominee, such as a bank, broker, dealer or other financial institution, please be sure to instruct your nominee how to vote to ensure that your vote is counted on all of the proposals.

If you are a Beneficial Owner, in order to ensure your Ordinary Shares are voted in the way you would prefer, you must provide voting instructions to your bank, broker, dealer or other financial institution by the deadline provided in the materials you receive from your bank, broker, dealer or other financial institution.

What are “broker non-votes”?

As discussed above, when a Beneficial Owner does not give voting instructions to his or her bank, broker, dealer or other financial institution holding his or her Ordinary Shares as to how to vote on matters deemed to be “non-routine,” the bank, broker, dealer or other financial institution cannot vote the shares with respect to such non-routine matters. These un-voted Ordinary Shares are counted as “broker non-votes.” Proposals 2, 5, 6, 8 and 9 are considered to be “non-routine” and therefore we expect broker non-votes to exist in connection with these proposals. We don’t expect any broker non-votes with respect to the routine proposals. Broker non-votes will have no effect on the non-routine proposals and do not count for purposes of determining whether a quorum is present or for the purpose of determining the number of votes cast.

What is an abstention and how will abstentions be treated?

An “abstention” represents a shareholder’s affirmative choice to decline to vote on a proposal. Under Dutch law and the Company’s articles of association (the “articles of association”), Ordinary Shares abstaining from voting will not count as votes cast at the Annual General Meeting, but will count as Ordinary Shares present and entitled to vote for purposes of determining a quorum.

How are proxies solicited for the Annual General Meeting?

We will pay the cost of soliciting proxies. Our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one set of proxy materials?

If you receive more than one set of proxy materials, your Ordinary Shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each notice to ensure that all of your Ordinary Shares are voted.

Can I change my vote after submitting my proxy?

Yes. You may revoke your submitted proxy and change your vote prior to the Cut-off Time:

5

Your most recent proxy card or telephone or Internet proxy is the one that will be counted. You may also attend the Annual General Meeting in person and revoke your proxy at the meeting or grant a separate proxy in writing to a representative who may attend the Annual General Meeting in person and revoke your prior proxy at the meeting on your behalf, provided in each case that you submit an Attendance Notice to the Company no later than the Cut-Off Time in accordance with the procedures outlined in the proxy statement.

If your Ordinary Shares are held by your bank, broker, dealer or other financial institution as a nominee, you should follow the instructions provided by such bank, broker, dealer or other financial institution to change or revoke an earlier instruction.

How many votes are needed to approve each proposal?

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

6

What is the quorum requirement?

A quorum must be present at the Annual General Meeting for any voting item to be voted on. At the Annual General Meeting, at least one-third of the Company’s issued and outstanding Ordinary Shares must be represented in order to constitute a quorum. On the Record Date, there were     Ordinary Shares outstanding and entitled to vote. Thus, the holders of     Ordinary Shares must be deemed present in person or represented by proxy at the Annual General Meeting to have a quorum.

Your Ordinary Shares will be counted toward the quorum only if you submit a valid proxy (or one is submitted on your behalf by your bank, broker, dealer or other financial institution) or if you are present or represented in person at the Annual General Meeting. Abstentions will be counted towards the quorum requirement.

How are votes counted?

Broadridge Financial Solutions (“Broadridge”) will tabulate the votes submitted by proxy prior to the Cut-off Time as described in this proxy statement. NautaDutilh N.V., our Dutch legal counsel, will tabulate the votes validly cast at the Annual General Meeting by those present at the meeting, if any. These tabulations will be provided to the Company.

How can I find out the results of the voting at the Annual General Meeting?

Preliminary voting results will be announced at the Annual General Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual General 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 General 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.

Proposal 8

Non-Binding, Advisory Vote to Approve the 2024 Compensation of Named Executive Officers

We are providing our shareholders with the opportunity to cast a non-binding, advisory vote regarding the compensation of our named executive officers (“NEOs”) as required pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

As more fully described in the sections of this proxy statement entitled “Executive Compensation” and “Compensation Discussion and Analysis” and related compensation tables, our executive compensation program is designed to attract, retain and motivate highly skilled individuals with the qualities, capabilities, profile and experience needed to support and promote the growth and sustainable success of the Company and its business.

The following proposal gives our shareholders the opportunity to endorse or not to endorse the 2024 compensation paid to our NEOs. The vote is not intended to address any specific item of compensation or the compensation of any particular NEO, but rather the overall compensation of our NEOs and our compensation philosophy, policies and practices as discussed in this proxy statement.

Before voting, we recommend you read the sections of this proxy statement entitled “Executive Compensation” and “Compensation Discussion and Analysis” for additional details on our executive compensation program and philosophy.

This vote is advisory, and therefore not binding on us, the Board of Directors or its compensation committee (the “Compensation Committee”). However, our Board of Directors and Compensation Committee value the opinions of our shareholders and intend to take into account the outcome of the vote when considering future compensation decisions for our NEOs.

Vote Required

This proposal requires a simple majority of votes cast in favor of the proposal. Abstentions and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. However, abstentions will count as Ordinary Shares present and entitled to vote for purposes of determining a quorum.

Recommendation of the Board of Directors

The Board of Directors unanimously recommends a vote FOR, on a non-binding, advisory basis, the approval of the 2024 compensation of our NEOs.

16

Proposal 9

Non-Binding, Advisory Vote Regarding Frequency of Future Shareholders’ Advisory Votes on Compensation of Named Executive Officers

We are asking shareholders to indicate their preference on the frequency of future advisory votes on the compensation of our NEOs. Shareholders may vote in favor of a frequency of such vote of every 1 year, 2 years or 3 years, or abstain from voting.

The Board of Directors believes that an annual advisory vote on the compensation of our NEOs will provide the most timely feedback regarding our executive compensation practices. While the Board of Directors believes that its recommendation is appropriate at this time, the vote is being conducted on a non-binding, advisory basis and the option among those choices that receives the highest number of votes will be deemed to be the frequency preferred by the shareholders but will not be binding upon the Board of Directors.

Vote Required

The choice receiving the highest number of votes will be given due regard for, but will not be binding on, the Board of Directors. Abstentions and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. However, abstentions will count as Ordinary Shares present and entitled to vote for purposes of determining a quorum.

Recommendation of the Board of Directors

The Board of Directors unanimously recommends a vote for, on a non-binding, advisory basis, a shareholder vote on named executive officer compensation to take place every 1 YEAR.

Executive Compensation Components

Our executive compensation program generally consists of, and is intended to strike a balance among, the following three principal components: base salary, annual performance-based cash bonuses and long-term incentive equity grants. We also provide our executive officers with severance and change-in-control benefits, as well as other benefits available to all our employees, including retirement benefits under the Company’s U.S. 401(k) plan, retirement arrangements for employees in other countries and participation in employee benefit

25

plans. The following chart summarizes the key features and objectives of the three main elements of compensation.

Compensation Program Governance

The Compensation Committee assesses the effectiveness of our executive compensation program from time to time and reviews risk mitigation and governance matters, which includes maintaining the following best practices:

26

Compensation Determination Process

Role of our Shareholders

Our shareholders have adopted a formal, written compensation policy in accordance with Dutch law. Changes to the compensation policy will require a vote of the General Meeting by simple majority of votes cast. The Board of Directors and the Compensation Committee determine the compensation of individual directors and executive officers with due observance of the compensation policy to the extent applicable.

We are conducting, for the first time, the advisory vote to approve the compensation of named executive officers and the advisory vote regarding frequency of future shareholders’ advisory votes on the compensation of named executive officers, as a result of the loss of our status as an “emerging growth company” as of December 31, 2024.

Role of the Compensation Committee

The Compensation Committee establishes the compensation philosophy and objectives (in accordance with the compensation policy), determines the structure, components and other elements of executive compensation, and reviews and approves the compensation of the NEOs or recommends it for approval by the Board of Directors. The Compensation Committee structures the executive compensation program to accomplish its articulated compensation objectives in light of the compensation philosophy described above.

The Compensation Committee annually reviews compensation policies and procedures to determine if any updates are needed. The Compensation Committee also approves, or recommends to the Board of Directors for approval, the corporate objectives associated with our annual performance-based cash incentive program, as well as assessing the Company’s performance against those corporate objectives after the end of the year or making a recommendation to the Board of Directors as to the extent to which the Company has met those corporate objectives.

The Compensation Committee meets periodically throughout the year to manage and evaluate our executive compensation program, and generally determines executive compensation on an annual basis, typically at the beginning of each fiscal year; however, decisions may occur during the year for new hires, promotions or other special circumstances as the Compensation Committee determines appropriate.

27

Role of the CEO and Management

The Compensation Committee generally seeks the input of our Chief Executive Officer (“CEO”) when discussing the performance of, and compensation for, our executive officers, including the NEOs other than the CEO. Our CEO is instrumental in developing both our annual and long-term strategic objectives and goals, which are reviewed and approved by the Compensation Committee and the Board of Directors. Our CEO is also instrumental in providing perspective on our performance against those goals.

Our CEO reviews the performance of the other executive officers, including the other NEOs, annually and presents his conclusions to the Compensation Committee. Our CEO then provides corresponding compensation recommendations, including as to base salary adjustments, annual performance-based cash compensation targets and payouts, and equity awards. The Compensation Committee considers the CEO’s input as one factor in its deliberations to determine the compensation of our executive officers, including the other NEOs. The Compensation Committee gives significant weight to the recommendations of the CEO in light of his greater familiarity with the day-to-day performance of his direct reports and the importance of incentive compensation in driving the execution of managerial initiatives developed and led by the CEO.

While the CEO may attend Compensation Committee meetings, the CEO may not be present during voting or deliberations on his compensation and does not play a role in determining his compensation.

In addition, other members of management may attend Compensation Committee meetings to provide background information or advice, or to answer questions posed by members of the Compensation Committee, including with respect to the financial, accounting, tax and retention implications of various compensation decisions.

Role of the Independent Compensation Consultant

The Compensation Committee recognizes that there is value in procuring independent, objective expertise in connection with fulfilling its duties, and pursuant to its charter, the Compensation Committee has the authority to select and retain advisors to assist it with carrying out its duties and responsibilities.

The Compensation Committee has engaged the services of an independent compensation consultant, the Human Capital Solutions practice of Aon plc (“Aon”), to assist it in connection with making executive compensation decisions. The Compensation Committee has worked with Aon to develop a peer group, to provide a competitive market analysis of the base salary, annual performance-based cash incentive awards and long-term incentive compensation of our executive officers compared against the peer group, and to review other market practices and trends with respect to executive compensation.

The Compensation Committee annually assesses the independence of Aon pursuant to SEC and Nasdaq rules. In 2024, the Compensation Committee assessed the independence of Aon consistent with Nasdaq listing standards and concluded that the engagement of Aon does not raise any conflict of interest.

While the Compensation Committee took into consideration the review and recommendations of Aon when making decisions about our executive compensation program, ultimately, the Compensation Committee made its own independent decisions in determining our executives’ compensation.

Consideration of Comparative Market Data

The Compensation Committee believes that obtaining relevant market and benchmark data is important to making determinations about executive compensation. This information provides a solid reference point and helpful context for making compensation decisions, even though, relative to other companies, there are differences and unique aspects of the Company.

28

With Aon’s assistance and input, the Compensation Committee annually adopts a peer group of companies that it uses as a reference group to provide a broad perspective on competitive pay levels and practices.

In doing so, the Compensation Committee seeks to approve a peer group that is representative of the sector in which we operate and includes companies within an appropriate defined range in terms of key attributes.

In October 2023, the Compensation Committee determined that our peer group for determining the compensation of our NEOs in 2024 would consist of Phase 2 and Phase 3 biopharmaceutical/biotechnology companies. In general, the selection criteria consisted of the following:

Based on these criteria, the peer group for setting 2024 compensation consisted of the following 24 companies:

The Compensation Committee utilizes the compensation of executive officers of the companies in this peer group as one reference point in the compensation-setting process along with various other factors, such as the executive’s performance, experience, and competitive market conditions.

Additionally, when considering the establishment of 2024 compensation levels for our NEOs, the Compensation Committee, upon recommendation from Aon, supplemented the 2024 peer group long-term incentive market data with data derived from the Radford 2023 Global Life Science Survey for public pre-commercial biopharma companies with under 150 employees. This survey data was used to obtain a general understanding of the compensation practices of companies similar to ours at the time.

The Compensation Committee believes that the compensation practices of our peer group, together with the data derived from the Radford 2023 Global Life Science Survey, provided us with appropriate compensation reference points for evaluating and determining the compensation of our NEOs during 2024.

2024 Executive Compensation Program

Our executive compensation program generally consists of, and is intended to strike a balance among, the following three principal components: base salary, annual performance-based cash bonus, and long-term incentive equity compensation.

CEO and NEO Pay Mix

Though the Compensation Committee has not adopted any formal or informal policies or guidelines that specify the allocation of compensation between these three elements, consistent with our “pay-for-performance”

29

philosophy, the Compensation Committee has determined that NEO compensation packages must include an emphasis on and substantial portion of variable, at-risk pay while ensuring adequate base salary to attract and retain talent. The Compensation Committee considers compensation to be at-risk if it is subject to performance-based payment or vesting conditions or if its value depends on share price appreciation.

Our executive compensation is linked strongly to the performance of the business, with a majority of annual target compensation being variable and at-risk. In 2024, 90% of the total target compensation for the CEO was at-risk and 77% of the total target compensation for all other NEOs was at-risk. The following pay mix pie chart graphics illustrate our emphasis on variable, at-risk pay and long-term incentives.

The percentages of target total direct compensation as calculated above are based on the annualized 2024 base salary, the 2024 annual cash incentive compensation opportunity (assuming achievement at the target level), and the grant date fair value of the annual option grants to NEOs. Each compensation element is described in this section and outlined in more detail in the Summary Compensation Table and Grants of Plan-Based Awards table below.

Base Salary

We provide our executive officers with fixed cash compensation in the form of a base salary. In establishing base salaries, the Compensation Committee exercises its judgment and discretion and considers several factors, including the performance of the individual executive officer, the officer’s potential to contribute to our long-term strategic goals, the officer’s role and scope of responsibilities within our Company, individual experience and skills, the officer’s compensation as compared to similarly situated executives at comparable companies in our peer group, competitive market dynamics for the position, and (with respect to other NEOs) the input of our CEO. None of our NEOs is currently party to an employment agreement or other agreement or arrangement that provides for automatic or scheduled increases in base salary.

Annual base salaries for our NEOs for the positions they held as of December 31, 2024, as compared with their annual base salaries as of December 31, 2023, were as follows:

30

Annual Performance-Based Cash Bonus

The annual cash incentive bonus plan (the “Annual Bonus Plan”) is a cash-based plan that rewards executive officers for the achievement of key short-term objectives. The structure of the Annual Bonus Plan incentivizes executive officers to achieve research, clinical, operational, and organizational results that the Compensation Committee views as critical to the execution of our business strategy.

For the NEOs, the amount of the payout, if any, under the Annual Bonus Plan is based on operational performance as well as individual performance. The Annual Bonus Plan gives considerable weight to achievement of key corporate and individual goals, while providing the Compensation Committee with the ability to exercise its best judgment in determining the overall level of achievement of such goals.

Target Opportunities. The Compensation Committee determines the target cash incentive opportunity available to each NEO by taking the individual’s annual base salary in effect for the year and multiplying it by the individual’s target incentive percentage. Among other factors, the target incentive percentages are determined with reference to the peer group company percentages of salary for the respective positions and the proportion of total direct compensation represented by the annual cash incentive. For 2024, our NEOs had the following annual cash bonus targets:

Corporate Performance Goals. As a pre-commercial biopharmaceutical company, we do not have material revenue or profits at this stage, and our success is measured by achievement of research and development milestones and other key strategic and operational goals.

In evaluating corporate performance, the Compensation Committee considered our achievement against the 2024 corporate goals as follows:

31

Corporate Performance Goals and Related Payouts. If we do not achieve an objective of corporate performance, there is no corresponding amount to be included in the payout related to that element. If we achieve the objective, the Compensation Committee will authorize a payout of the portion of the overall opportunity allocated to that element; if we exceed the objective by achieving a stretch goal, the Compensation Committee may, in its discretion, authorize a higher payout, but the total payout will not exceed 200% of an executive’s overall target incentive.

2024 Achievement of Corporate Goals. In January 2025, the Compensation Committee met to consider how the Company had performed against corporate performance goals. While the Compensation Committee considered management’s views regarding their 2024 achievements, the Compensation Committee made an independent determination regarding corporate performance, which included consideration of the following:

Clinical Research

In 2024, we announced updated clinical results for the following:

Corporate

32

Individual Performance. In determining Annual Bonus Plan payouts, the Compensation Committee also evaluated the individual performance of our NEOs. The Compensation Committee views the inclusion of individual performance as an important component of the annual cash bonus plan because it motivates the NEOs for individual performance, even if overall corporate performance is lower. In assessing the individual performance of our NEOs, the Compensation Committee, with the input of our CEO for the non-CEO NEOs, considered each such officer’s individual contributions to the achievement of our 2024 goals, and the officer’s individual performance in helping to execute on our strategic and operating initiatives.

Overall Payouts. Based on the assessment described above, the Compensation Committee recommended, and the Board of Directors determined, that the Company’s corporate performance exceeded the 2024 goals. The Compensation Committee determined an overall 2024 performance level, as determined with reference to both corporate performance and individual performance. The amounts of the annual bonus awards for 2024 were determined as follows:

Equity-Based Incentive Awards

The third and largest component of the executive compensation program is long-term equity incentives. The Compensation Committee designed the long-term incentive opportunity for the NEOs to motivate and reward executive officers to achieve multiyear strategic goals and deliver sustained long-term value to shareholders.

We believe that equity awards provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our shareholders. Long-term equity incentives also promote retention because executive officers will only receive value if they remain employed by us over the required term.

Grants to our NEOs and other employees are made at the discretion of the Compensation Committee and are generally made upon commencement of employment, promotion or annually during the first quarter of each year. We believe that our equity awards are an important retention tool for our executive officers, as well as for our other employees.

We have used stock option grants as our primary equity vehicle because we believe that they are an effective means by which to align the long-term interests of our executive officers with those of our shareholders. Among

33

companies that are similar to ours in terms of stage of development, options are very common as the form of equity awards. Share options can motivate stock price appreciation over the long term because they deliver value only if the stock price increases. The use of share options also can provide tax and other advantages to our executive officers relative to other forms of equity compensation.

In determining the number of options to be granted to an NEO, the Compensation Committee takes into account equally both the range of long-term incentive award values granted to executive officers at the companies in the peer group and the range of grant size as a percent of the companies in the peer group.

The annual option incentive awards granted to our NEOs are set forth in the table below:

The exercise price of all share option awards to NEOs is equal to the closing price of our shares on the date of the grant, and all share options granted in 2024 have a ten-year term. The options are subject to time-based vesting, with 25% of the total number of shares underlying the award vesting on the first anniversary of the date of grant and thereafter in equal monthly installments for 36 months, subject to the applicable NEO’s continued service through each such vesting date.

Additional Elements of Compensation

Employee Benefits

Our NEOs are eligible to participate in all our employee benefit plans, such as medical, dental, vision, group life, short and long-term disability and our 401(k) plan for U.S. employees, in each case on the same basis as other employees, subject to applicable laws. Under our 401(k) plan, the Company currently makes matching contributions of 100% of the first 3% and then 50% of the next 2% of employee contributions. We believe these benefits are important to attracting and retaining experienced employees, including our executives.

Ms. Audet resides in Switzerland and is employed by the Company in Switzerland. In 2024, the Company made contributions to Ms. Audet’s statutory Swiss pension plan account in accordance with Swiss law.

Perquisites

We do not provide material perquisites to our executive officers.

Severance and Change in Control Arrangements

We have entered into employment agreements with all our NEOs that provide for at-will employment without any specific term. Each of the agreements sets forth the NEO’s severance benefits payable upon a qualifying termination of employment or change in control of the Company. The “Potential Payments Upon Termination or Change in Control” section below describes and quantifies the severance and other benefits potentially payable to the NEOs in further detail.

34

These agreements provide for a combination of a cash severance payment, continued health benefits and acceleration of vesting on outstanding equity awards in specified circumstances. Acceleration of vesting is subject to a “double trigger” arrangement, meaning that vesting acceleration occurs only in the event of a change in control of the Company in connection with or followed by a termination of employment without cause by us, or with good reason by the NEO.

Given the industry in which we participate and the range of strategic initiatives that we may explore, we believe reasonable and competitive severance and change-in-control payment and benefit arrangements are an essential element of our executive compensation package and assist us in recruiting and retaining a talented executive team. We also believe such payments and benefits are in the best interests of our shareholders because they incentivize senior executives to continue to strive to achieve shareholder value in connection with change-in-control situations, particularly where the possibility of a change-in-control and the related uncertainty may lead to the departure or distraction of senior executives to the detriment of our Company and our shareholders.

We do not provide any excise tax gross ups in connection with severance paid upon termination without cause or relating to a change-in-control transaction. All change-in-control cash payments are structured to be on a “double-trigger” basis, requiring a termination without cause by us, or with good reason by the NEO, in connection with the change-in-control transaction.

Additional Compensation Policies and Practices

Clawback Policy

In 2023, the Compensation Committee of our Board adopted our Incentive Compensation Recoupment Policy (the “Clawback Policy”), designed to comply with Rule 10D-1 of the Exchange Act and Nasdaq Listing Rule 5608, which provides for recoupment of incentive compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting requirements under the relevant securities laws. The policy applies to our current and former executive officers. Compensation that is granted, earned or vested based wholly or in part upon attainment of a Financial Reporting Measure (as defined in the Clawback Policy) that is determined to have been paid erroneously given the restatement is subject to recoupment.

Equity Granting Practices

Neither the Compensation Committee nor the Board takes material nonpublic information into account when determining the timing and terms of equity awards. Stock options may occasionally be awarded on an off-cycle basis, including to new hires. The Company has not timed the disclosure of material nonpublic information to affect the value of executive compensation.

Anti-Hedging and Anti-Pledging Policies

We have a policy that prohibits our executive officers, directors and other employees from engaging in short sales, transactions in put or call options, or other inherently speculative transactions with respect to our shares. In addition, our insider trading policy prohibits pledging Company securities as collateral for a loan or ownership of Company securities in a margin account. Any violation of these policies may result in disciplinary action, including dismissal for cause.

Tax Considerations; Section 162(m)

When reviewing compensation matters, the Compensation Committee considers the anticipated tax consequences to us (and, when relevant, to our executive officers) of the various payments under our compensation programs. Section 162(m) of the Code generally disallows a tax deduction for any publicly held corporation for individual compensation of more than $1.0 million to certain executive officers in any taxable year. The Compensation Committee may provide compensation to executive officers that may not be tax deductible if it believes that providing that compensation is in the best interests of our Company and its shareholders.

35

Accounting Policies for Stock-Priced Compensation

We follow the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718 (“ASC 718”) for our stock-based compensation awards. ASC 718 requires companies to calculate the grant date “fair value” of their stock-based awards using a variety of assumptions. ASC 718 also requires companies to recognize the compensation cost of their stock-based awards in their income statements over the period that an employee is required to render service in exchange for the award. Grants of share options under our equity incentive award plans are accounted for under ASC 718. Our Board or Compensation Committee will regularly consider the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs.

Equity Incentive Plans

LTIP

We have established our LTIP, under which we may grant options, restricted shares, restricted share units, share appreciation rights and other equity and equity-based awards. As of December 31, 2024, the total number of Ordinary Shares underlying awards granted under the LTIP (other than awards granted as Earnout RSUs in accordance with the Business Combination Agreements or as replacement awards in connection with a merger or business combination) will not exceed 17,772,578; provided that the number of Ordinary Shares reserved for grant under the LTIP will increase annually on January 1 of each calendar year by 5% of the-then issued and outstanding Ordinary Shares or such lower number as may be determined by the Board of Directors.

The LTIP is administered by the Board of Directors and the Compensation Committee. The Board of Directors has delegated authority to grant awards under the LTIP to the Compensation Committee for awards to eligible participants not then serving on the Compensation Committee. The Board of Directors has also delegated the authority to grant awards under the LTIP to non-executive officers to Dr. Davidson who will determine when to grant equity awards and the terms of such awards. We may grant awards under the LTIP to our directors, employees, consultants or other advisors. The Board of Directors or the Compensation Committee may condition awards under the LTIP upon the achievement or satisfaction of performance criteria and/or continued service with the Company and determines the vesting conditions for awards under the LTIP. The LTIP includes provisions for good leavers and bad leavers as well as for change-in-control.

Rollover Option Plan

We also established a rollover option plan (the “Rollover Plan”) in connection with the closing of the Business Combination, under which we assumed the outstanding options of certain optionholders of NewAmsterdam Pharma Holding B.V. who held their options through entities in exchange for a grant of options to acquire Ordinary Shares. The total number of Ordinary Shares underlying the options covered by the Rollover Plan is 1,736,545. Any Ordinary Shares underlying options granted under the Rollover Plan that are forfeited, canceled or otherwise terminated will become available for issuance under the LTIP.

42

The Rollover Plan is administered by the Board of Directors and the Compensation Committee. The Rollover Plan includes provisions applicable in the event of a change-in-control.

Supplementary LTIP

We have also established our supplementary long-term incentive plan (the “Supplementary LTIP”), under which we may grant options, restricted shares, restricted share units, share appreciation rights and other equity and equity-based awards to our employees and consultants (but not our directors). The total number of Ordinary Shares underlying awards that may be granted under the Supplementary LTIP (other than awards granted as replacement awards in connection with a merger or business combination) will not exceed 1,040,233.

The Supplementary LTIP is administered by the Board of Directors and the Compensation Committee. The Board of Directors has delegated authority to grant awards under the Supplementary LTIP to the Compensation Committee for awards to anyone not then serving on the Compensation Committee. The Board of Directors has also delegated the authority to grant awards under the Supplementary LTIP to non-executive officers to Dr. Davidson, who will determine when to grant equity awards and the terms of such awards. The awards issued under the Supplementary LTIP will have terms substantially similar to those issued under the LTIP. The Supplementary LTIP includes provisions applicable in the event of a change-in-control.

Inducement Plan

We have also established our inducement plan (the “Inducement Plan”), under which we may grant options, restricted shares, restricted share units, share appreciation rights and other equity-based awards to our newly-hired (or newly-hired, after a bona fide period of non-employment) employees (but not directors). The total number of Ordinary Shares underlying awards that may be granted under the Inducement Plan will not exceed 1,500,000.

The Inducement Plan is administered exclusively by the Compensation Committee. The Inducement Plan includes provisions applicable in the event of a change-in-control.

Limitation of Liability and Indemnification

Under Dutch law, our directors may be held liable for damages in the event of improper or negligent performance of their duties. They may be held liable for damages to the Company and to third parties for infringement of the Articles of Association or of certain provisions of Dutch law. In certain circumstances, they may also incur other specific civil, administrative and criminal liabilities. Subject to certain exceptions, the Articles of Association provide for indemnification of our current and former directors and other current and former officers and employees as designated by the Board of Directors. No indemnification under the Articles of Association will be given to an indemnified person:

43

Under the Articles of Association, the Board of Directors may stipulate additional terms, conditions and restrictions in relation to the indemnification described above.

We have also entered into indemnification agreements with each of our directors and executive officers providing for procedures for indemnification and advancements by us of certain expenses and costs relating to claims, suits or proceedings arising from his or her service to us or, at our request, service to other entities, as officers or directors to the maximum extent permitted by Dutch law and subject to the exceptions provided in such agreements.

44

Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information

We do not have any program, plan or obligation that requires us to grant equity awards on specified dates, although the Company’s practice has been to make annual equity determinations in early January of each year at the meetings of our Compensation Committee and Board, with such grants effective on the first trading day of the year. We believe this allows management, the Compensation Committee and the Board to conduct a fulsome review of all elements of compensation on a consistent basis each year.

Neither the Compensation Committee nor the Board takes material nonpublic information into account when determining the timing and terms of equity awards. Stock options may occasionally be awarded on an off-cycle basis, including to new hires. The Company has not timed the disclosure of material nonpublic information to affect the value of executive compensation.

Pursuant to Item 402(x) of Regulation S-K under the Exchange Act, we are providing the following information regarding awards granted to named executive officers of the Company on the following dates:

DIRECTOR COMPENSATION

The Board of Directors and the Compensation Committee determine the compensation of individual directors in accordance with our compensation policy to the extent applicable. All non-employee directors are paid an annual retainer of $43,000. Non-employee directors may receive further compensation ranging from $5,000 to $20,000 for serving as chair or member of committees (i.e., Audit Committee or Compensation Committee). We have also granted and expect to continue granting certain non-employee directors, other than those affiliated with our significant shareholders, options to purchase Ordinary Shares as compensation for their service on the Board of Directors.

Director Service Agreement

We entered into services agreements with all of our directors which regulate their services as our directors. These services agreements, except for James N. Topper’s services agreement, contain non-competition and non-solicitation arrangements, as well as a requirement to assign and transfer to us any intellectual and industrial property rights originating from the director’s services as a director or inventor for us, but do not provide for compensation.

Director Indemnification Agreements

The Articles of Association require us to indemnify our current and former directors to the fullest extent permitted by law, subject to certain exceptions. We entered into indemnification agreements with all of our directors providing for procedures for indemnification and advancements by us of certain expenses and costs relating to claims, suits or proceedings arising from their service to us or, at our request, service to other entities, as directors or officers to the maximum extent permitted by law.

Director Compensation Table

The following table sets forth information regarding the compensation earned for service on the Board of Directors by our non-employee directors during the year ended December 31, 2024.

CORPORATE GOVERNANCE

This section provides further information regarding the Board of Directors and the independence of our directors and describes key corporate governance practices that we have adopted.

Board Structure

We are a Dutch public limited liability company (naamloze vennootschap) with a single-tier board currently consisting of one executive director and ten non-executive directors. Drs. Topper and Downing were initially designated to serve on the Board of Directors by Frazier Lifesciences and Dr. Davidson, Dr. Kastelein and Dr. Lange were initially designated by NewAmsterdam Pharma pursuant to the terms of the Business Combination Agreement, dated as of July 25, 2022 (the “Business Combination Agreement,” and the transactions contemplated by the Business Combination Agreement, the “Business Combination”). Our directors do not have a retirement age requirement under the articles of association. Mr. Lewis and Mr. McKenna serve as the Chair and Vice Chair, respectively, of the Board of Directors. The Chair and in his absence, the Vice Chair, is responsible for ensuring there is sufficient contact between the Board of Directors and the executive director, that the Board of Directors has sufficient access to information and sufficient time to deliberate and make decisions, monitoring director performance and otherwise administering the Board of Directors process. There are no family relationships among any of our directors.

Our directors will be (re-)appointed by our shareholders upon a binding nomination by the Board of Directors. The shareholders may overrule a binding nomination by a resolution adopted by a majority of at least two thirds of the votes cast, provided such majority represents more than half of the issued share capital. If our shareholders overrule a binding nomination, the Board of Directors will make a new nomination.

The Dutch Corporate Governance Code provides the following best practice recommendations on the terms for tenure of our directors:

Our shareholders may at any time seek to suspend or dismiss a director at a general meeting of our shareholders. If a proposal to suspend or dismiss a director is properly brought before a general meeting of our shareholders, shareholders may only adopt a resolution to suspend or dismiss a director by a majority of at least two thirds of the votes cast, provided such majority represents more than half of the issued share capital, unless the resolution is adopted at the proposal of the Board of Directors, in which latter case the resolution may be adopted by a simple majority of the votes cast.

Independence of the Board of Directors

The Nomination and Corporate Governance Committee and Board of Directors have undertaken a review of the independence of our directors and considered whether any director has a relationship that, in the opinion of such committee or the Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a member of the Board of Directors. Based upon information requested from and provided by each director concerning such director’s background, employment and affiliations, including family relationships, the Board of Directors has determined that all of our directors, other than Dr. Davidson, Dr. Kastelein and Dr. Topper, are “independent directors,” as such term is defined in Nasdaq Rule 5605(a)(2). In making these determinations, the Board of Directors considered the current and prior relationships that each director has with the Company and all other facts and circumstances that the Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each director.

52

Director Attendance at Board and Shareholder Meetings

The Board of Directors met four times during 2024, either in person, by teleconference or videoconference. No directors attended fewer than 75% of the Board of Directors meetings or meetings of a committee on which they served.

The then-current directors that attended our 2024 annual general meeting of shareholders either in person or by teleconference include William H. Lewis, Michael Davidson, M.D., Louis Lange, M.D., Ph.D. Nick S. Downing, and John W. Smither.

Board of Directors Committees

The Board of Directors has established three standing committees: an audit committee, a compensation committee and a nomination and corporate governance committee. Each committee operates under a charter that has been approved by the Board of Directors. Current copies of each committee’s charter are posted on the “Corporate Governance Overview” section of our website, https://ir.newamsterdampharma.com/corporate-governance/governance-overview. Our website and its contents are not incorporated into this proxy statement.

The current members of the committees are as follows:

Audit Committee

The Audit Committee consists of John W. Smither, William H. Lewis and Mark McKenna. Mr. Smither serves as chairperson of the Audit Committee. The Audit Committee assists the Board of Directors in, among other things:

The Audit Committee has the authority to retain independent counsel and advisors to assist in carrying out its responsibilities.

Each member of the Audit Committee is an “independent director,” as such term is defined in Nasdaq Rule 5605(a)(2) and meets the criteria for independence set forth in Rule 10A-3(b)(1) under the Exchange Act. The Board of Directors has also determined that each of the Audit Committee members is able to read and understand fundamental financial statements and that at least one member of the Audit Committee has past employment experience in finance or accounting. The Board of Directors has determined that Mr. Smither qualifies as an “audit committee financial expert,” as such term is defined in the rules of the SEC.

The Audit Committee held four meetings during 2024.

53

Compensation Committee

The Compensation Committee consists of Louis Lange, M.D., Ph.D., William H. Lewis and Mark McKenna. Dr. Lange serves as chair person of the Compensation Committee. The Compensation Committee assists the Board of Directors in, among other things:

The Compensation Committee has the authority to retain independent counsel and other advisors, including compensation consultants, to assist in carrying out its responsibilities.

Each member of the Compensation Committee is an “independent director,” as such term is defined in Nasdaq Rule 5605(a)(2) and meets the criteria for independence set forth in Rule 10A-3(b)(1) under the Exchange Act.

The Compensation Committee held four meetings during 2024.

Nomination and Corporate Governance Committee

The Nomination and Corporate Governance Committee consists of Janneke van der Kamp, William H. Lewis, Nicholas Downing and Louis Lange, M.D., Ph.D. Mr. Lewis serves as chairperson of the Nomination and Corporate Governance Committee. The Nomination and Corporate Governance Committee assists the Board of Directors in, among other things:

The Nomination and Corporate Governance Committee has the authority to retain independent counsel and other advisors to assist in carrying out its responsibilities. The Nomination and Corporate Governance Committee also assists the Board of Directors in regularly reviewing the size and composition of the Board of Directors and the independence of directors and director nominees.

Each member of the Nomination and Corporate Governance Committee is an “independent director,” as such term is defined in Nasdaq Rule 5605(a)(2) and meets the criteria for independence set forth in Rule 10A-3(b)(1) under the Exchange Act.

54

The Nomination and Corporate Governance Committee did not hold any meetings during 2024. During 2024, the Nomination and Corporate Governance Committee took various actions by unanimous written consent. The Nomination and Corporate Governance Committee also met informally on a periodic basis and had discussions with the Board of Directors on various matters.

Director Nomination Process

The Board of Directors may consist of one or more executive directors and up to ten non-executive directors. The Board of Directors currently consists of one executive director and ten non-executive directors. Two of our non-executive directors, Drs. Topper and Downing, were initially designated by Frazier Lifesciences and our other initial directors, Dr. Davidson, Dr. Kastelein and Dr. Lange, were initially designated by NewAmsterdam Pharma pursuant to the terms of the Business Combination Agreement.

The Nomination and Corporate Governance Committee is responsible for recruiting and considering director candidates and presents qualified candidates to the full Board of Directors for consideration in accordance with the Board of Directors’ profile, the Board Rules and the Nomination and Corporate Governance Committee’s charter, each of which is available on our website. Our website and its contents are not incorporated into this proxy statement. Director candidates are evaluated using certain established criteria, including a nominee’s general business and industry experience, finance and management experience, other operational experience, ability to act on behalf of shareholders, independence or conflicts of interest and the other general criteria set forth in the Board of Directors’ profile and any other specific additional criteria relevant in evaluating Board of Directors nominees.

We have adopted a Diversity Policy to emphasize our commitment to seeking to attain diversity and balance among directors taking into account a multitude of facets, such as identity, background, education, thought and experience. As a result, under our policies any search firm retained to assist the Nomination and Corporate Governance Committee in seeking candidates for the Board of Directors will be instructed to seek to include diverse candidates taking into account a multitude of facets. We believe that a Board of Directors comprised of directors with diverse skills and experiences relevant to our industry and operations will result in efficient and competent oversight of our various core competencies.

Qualified candidates will be considered without regard to race, color, religion, sex, ancestry, national origin or disability. The Nomination and Corporate Governance Committee does not have a formal policy with respect to director candidates recommended by shareholders but may consider candidates it deems qualified from any source. The Board of Directors believes retaining the flexibility to consider a director candidate or ignore a director candidate if it determines doing so is in the best interest of the Company. If the Nomination and Corporate Governance Committee approves a candidate for further review they will establish an interview process for the candidate. The Nomination and Corporate Governance Committee will also take into consideration the candidate’s personal attributes, including, without limitation, personal integrity, loyalty, ability to apply sound and independent business judgment, awareness of a director’s vital part in our good corporate citizenship and image, time available for meetings and consultation on our matters and willingness to assume broad, fiduciary responsibility.

Each of the individuals nominated for appointment or re-appointment to the Board of Directors were approved for such nomination by the Nomination and Corporate Governance Committee.

Risk Management and Oversight

One of the Board of Directors’ key functions is overseeing the Company’s risk management process. The Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through various standing committees that address risks inherent in their respective areas of oversight. In particular, the Board of Directors, with the support of

55

management, is responsible for monitoring and assessing strategic risk exposure. Our Audit Committee has the responsibility to consider and discuss cybersecurity risks and our major financial risk exposures. Our Nomination and Corporate Governance Committee monitors the effectiveness of our executive officers and directors and overseeing the risks related to hiring and retention. Our Compensation Committee assesses and monitors risks arising from any of our compensation policies.

Shareholder Dialogue with the Company

The Board of Directors recognizes the importance and value of robust dialogue with shareholders and has adopted an Investor Dialogue Policy to guide interactions between Company representative and shareholders. The Board of Directors strives to keep the Company’s shareholders updated throughout the year through regular press releases and SEC filings. Investors can send communications to the Board of Directors by delivering their communication in writing to our principal executive offices. If the communication relates to our financial statements, accounting practices or internal controls, the information will be shared with the chairperson of the Audit Committee. If the matter relates to our governance practices, business ethics or corporate conduct, the information will be shared with the chairperson of the Nomination and Corporate Governance Committee. If a shareholder wishes to address a communication to an individual director, it should be submitted in writing addressed to such individual director in care of the principal accounting officer at our principal executive offices. The Board of Directors has also adopted a Stakeholder Dialogue Policy outlining the principles for the Company’s interactions with investors, employees, creditors, business partners, community members and other interested parties. The Company is committed to engaging with these stakeholders from time to time and may respond to stakeholder initiated dialogue when the Board of Directors determines doing so would be in the Company’s best interests. In engaging with shareholders and other stakeholders the Company will be represented by at least one director, or in appropriate circumstances, a member of management.

SECURITIES AUTHORIZED FOR ISSUANCE UNDER EQUITY COMPENSATION PLANS

Our LTIP and Rollover Plan are our only equity compensation plans approved by our shareholders. The Supplementary LTIP and the Inducement Plan were approved by the Board of Directors but were not approved by our shareholders. The following table sets forth certain information as of December 31, 2024 with respect to our LTIP, Rollover Plan, Supplementary LTIP and Inducement Plan:

59

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Review, Approval or Ratification of Transactions with Related Persons

We adopted a related party transaction policy that requires the review and, if applicable, approval or ratification of any related party transaction by the Board of Directors, the Audit Committee or another designated committee consisting solely of independent directors. Our Audit Committee will review this related party transaction policy periodically and will recommend changes to the Board of Directors as appropriate.

In addition, under Dutch law and the Articles of Association, our directors may not take part in any discussion or decision-making that involves a subject or transaction in relation to which he or she has a direct or indirect personal conflict of interest with us. Such a conflict of interest would generally arise if the director concerned is unable to serve our interests and the business connected with us with the required level of integrity and objectivity due to the existence of the conflicting personal interest. The Articles of Association provide that if as a result of conflicts of interests no resolution of the Board of Directors can be adopted, the resolution may nonetheless be adopted by the Board of Directors as if none of our directors had a conflict of interest. In that latter case, each of our director is entitled to participate in the discussion and decision-making process and to cast a vote.

A related party transaction is generally any transaction in which the Company or its subsidiaries is or will be a participant, in which the amount involved exceeds $120,000, and a director (or nominee), executive officer, immediate family member, or any beneficial owner of more than 5% of our Ordinary Shares, has or will have a direct or indirect material interest.

Certain Related Party Transactions

Investor Rights Agreement

In connection with the closing of the Business Combination, we entered into the Investor Rights Agreement, dated November 22, 2022 (the “Investor Rights Agreement”), with the Sponsor and the former FLAC directors (the “FLAC Initial Shareholders”), and certain NewAmsterdam Pharma shareholders agreed not to sell, assign, offer to sell, contract, pledge, grant, or otherwise dispose of or enter into any swap or other similar arrangement, with respect to the Ordinary Shares such persons received in connection with the Business Combination for six months from the date the Domestication became effective (the “Final Closing Date”), subject to certain limited exceptions. In addition, the FLAC Initial Shareholders agreed not to sell, assign, offer to sell, contract, pledge, grant, or otherwise dispose of or enter into any swap or other similar arrangement, with respect to the Ordinary Shares they received in connection with the Business Combination for a period beginning on the Final Closing Date and ending one year after the Final Closing Date. Notwithstanding the foregoing, the restrictions above ended with respect to the Ordinary Shares held by the NewAmsterdam Pharma shareholders and 50% of the Ordinary Shares held by the FLAC Initial Shareholders, as the case may be, received in connection with the Business Combination, on May 22, 2023 according to the terms of the Investor Rights Agreement. The restrictions on the remaining 50% of the Ordinary Shares of the FLAC Initial Shareholders received in connection with the Business Combination ended on November 23, 2023, one year after the Final Closing Date. An aggregate of 44,914,642 Ordinary Shares held by former NewAmsterdam Pharma shareholders (including Saga Investments Coöperatief U.A. and Mitsubishi Tanabe Pharma Corporation) had registration rights pursuant to the terms of the Investor Rights Agreement.

In June 2023, certain of our selling securityholders (the “Selling Securityholders”) exercised their right pursuant to the Investor Rights Agreement to demand an underwritten shelf takedown of Ordinary Shares. On June 6, 2023, the Company and certain of the Selling Securityholders, including affiliates of Forbion, entered into an Underwriting Agreement (the “Underwriting Agreement”) with Jefferies LLC and SVB Securities LLC, as representatives of the several underwriters named therein (the “Underwriters”). The Underwriting Agreement related to an underwritten public offering of 13,857,415 Ordinary Shares by those certain Selling Securityholders

60

at a public offering price of $11.50 per Ordinary Share (the “Secondary Offering”). In connection with the Secondary Offering, certain of the participating Selling Securityholders granted the Underwriters a 30-day option to purchase an additional 2,078,612 Ordinary Shares at the public offering price, less underwriting discounts and commissions, which option was partially exercised for 1,930,280 additional Ordinary Shares in connection with the closing of the Secondary Offering. The Company did not sell any Ordinary Shares in the Secondary Offering and did not receive any proceeds from the Secondary Offering.

Indemnification Agreements

The Articles of Association provide for certain indemnification rights for our current and former directors and other current and former officers and employees as designated by the Board of Directors (the “Indemnified Persons”). Specifically, we indemnify the Indemnified Persons against any financial losses or damages and any expense reasonably paid or incurred in connection with any threatened, pending or completed suit, to the extent these relate to such Indemnified Persons’ current or former position with the Company as permitted by applicable law.

We have also entered into indemnification agreements with each of our directors and executive officers providing for procedures for indemnification and advancements by us of certain expenses and costs relating to claims, suits or proceedings arising from his or her service to us or, at our request, service to other entities, as officers or directors to the maximum extent permitted by Dutch law and subject to the exceptions provided in such agreements.

Employment Agreements

See the section titled “Executive Compensation—Employment Agreements and Change of Control Agreements” above for a further discussion of these arrangements.

61

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information regarding the actual beneficial ownership of Ordinary Shares as of April 15, 2025, by:

The SEC has defined “beneficial ownership” of a security to mean the possession, directly or indirectly, of voting power and/or investment power over such security. A shareholder is also deemed to be, as of any date, the beneficial owner of all securities that such shareholder has the right to acquire within 60 days after that date through (i) the exercise of any option, warrant or right, (ii) the conversion of a security, (iii) the power to revoke a trust, discretionary account or similar arrangement, or (iv) the automatic termination of a trust, discretionary account or similar arrangement. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, Ordinary Shares subject to options or other rights (as set forth above) held by that person that are currently exercisable, or will become exercisable within 60 days thereafter, are deemed outstanding, while such shares are not deemed outstanding for purposes of computing percentage ownership of any other person. Each person named in the table has sole voting and investment power with respect to all of the Ordinary Shares shown as beneficially owned by such person, except as otherwise indicated in the table or footnotes below.

62

The beneficial ownership of Ordinary Shares is based on 112,170,677 Ordinary Shares issued and outstanding, as of April 15, 2025. Unless otherwise indicated, we believe that all persons named in the table below have sole voting and investment power with respect to all Ordinary Shares beneficially owned by them. To our knowledge, no Ordinary Shares beneficially owned by any executive officer, director or director nominee have been pledged as security. None of our shareholders has different voting rights from other shareholders.
