The agenda with the explanatory notes thereto, our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and the other meeting information are available as of the date hereof for inspection and can be obtained free of charge at the office address of the Company and at www.proxyvote.com. Our Dutch statutory board report and statutory annual accounts for the fiscal year ended December 31, 2023 will be available no later than May 21, 2024 on our website at https://www.newamsterdampharma.com/.

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 as at 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 3, 2024 (5:59 a.m. CEST on June 4, 2024) (the “Cut-off Time”). 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. Persons with Meeting Rights and Beneficial Owners who have duly provided a valid Attendance Notice to the Company may have themselves represented at the Annual General Meeting through the use of a written or electronically recorded proxy. Proxyholders must submit a signed proxy no later than the Cut-off Time and present a copy of their proxy upon entry to the Annual General Meeting.

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. If you attend the Annual General Meeting, you may withdraw your proxy and vote your shares personally.

Who is soliciting my vote?

NewAmsterdam Pharma Company N.V.

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. Instructions on how to access the proxy materials over the internet or to request a printed set of the proxy materials can be found in this proxy statement (the “proxy statement”).

We intend to mail the proxy statement on or about     , 2024 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 5, 2024 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 8, 2024 (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 3, 2024 (5:59 a.m. CEST on June 4, 2024) (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 seven matters scheduled for a vote:

Who can vote at the Annual General Meeting?

Only shareholders of record at the close of business 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.

2

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 all proposals, you may vote “For” or “Against,” 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 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:

3

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 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 and 6 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.

4

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 and 6 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:

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.

5

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.

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 towards 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.

6

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.

For a proposal to be considered for inclusion in our proxy materials for presentation at the 2025 annual general meeting of shareholders pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the proposal must comply with the requirements of Rule 14a-8 and be received by our Chief Accounting Officer at our principal executive offices at Gooimeer 2-35, 1411 DC Naarden, The Netherlands, by no later than     , 2024 (120 days before the anniversary date of the release of this proxy statement to shareholders), unless the date of the 2025 annual general meeting of shareholders is changed by more than 30 days from the one-year anniversary of the Annual General Meeting, in which case the deadline will be a reasonable time before we begin to distribute the proxy materials for the 2025 annual general meeting of shareholders.

Rule 14a-4 under the Exchange Act governs our use of our discretionary proxy voting authority with respect to a shareholder proposal that the shareholder has not sought to include in our proxy statement. Rule 14a-4 provides that if a proponent of a proposal fails to notify us at least 45 days prior to the one-year anniversary of the day of mailing of the prior year’s proxy statement, management proxyholders will be allowed to use their discretionary voting authority as to whether the proposal is raised at the annual general meeting, without any discussion of the matter. If a shareholder wishes to bring a matter before the shareholders at the 2025 annual general meeting of shareholders but does not notify us before     , 2025 (or a reasonable time before we begin to distribute the proxy materials for the 2025 annual general meeting of shareholders if the date of the 2025 annual general meeting of shareholders is changed by more than 30 days from the one-year anniversary of this year’s annual general meeting), for all proxies we receive, the management proxyholders will have discretionary authority to vote on the matter, including discretionary authority to vote in opposition to the shareholder’s proposal.

Future Shareholder Proposals under Dutch law

Under Dutch law and the articles of association, if a shareholder is interested in submitting a proposed agenda item or a proposed resolution within the authority of shareholders to be presented at the 2025 annual general meeting of shareholders, irrespective of whether they intend to have the proposal included in our proxy materials, the shareholder must fulfill the requirements set forth in Dutch law and the articles of association, including satisfying both of the following criteria:

In response to a proposed agenda item or a proposed resolution referred to above, the Board of Directors can invoke a response period of up to 180 days as provided for by the Dutch Corporate Governance Code or a cooling-off period of up to 250 days as provided for by Dutch law.

All notices of proposals by shareholders, whether or not requested for inclusion in the Company’s proxy materials, should be sent to our principal executive offices, attention to our Chief Accounting Officer.

In addition to satisfying the foregoing requirements under Dutch law and our articles of association, to comply with the SEC’s universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide the Company prior written notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 6, 2025 (unless the date of 2025

16

annual general meeting of shareholders is changed by more than 30 days from the one-year anniversary of this year’s Annual General Meeting, in which case the deadline to deliver the notice will be the later of (i) 60 calendar days prior to the date of the annual meeting and (ii) the 10th calendar day following the day on which we first make a public announcement of the date of the annual meeting).

EXECUTIVE COMPENSATION

Summary Compensation Table

The following table sets forth information regarding compensation awarded to or earned by our named executive officers.

Narrative to the Summary Compensation Table

We maintain a compensation policy consistent with Dutch law. Our compensation policy was adopted by the shareholders prior to the closing of the Business Combination. Changes to the compensation policy will require a vote of the shareholders by simple majority of votes cast. The Board of Directors and its compensation committee (the “Compensation Committee”) determine the compensation of individual executive officers with due observance of the compensation policy to the extent applicable.

Base Salary

Our named executive officers receive a base salary to compensate them for services rendered to the Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. The 2023 base salaries for our named executive officers are set forth in the table below, as well as the increased base salaries approved in December 2023.

24

Equity Compensation

Stock Options

Our named executive officers have been granted options to purchase our Ordinary Shares. The options we have granted to our executive officers are typically subject to time-based vesting and either vest (i) as to 25% of the Ordinary Shares underlying the option on the first anniversary of the grant date and thereafter in substantially equal monthly installments for an additional three years or (ii) in substantially equal monthly installments over four years, in each case, provided the executive officer remains employed with us as of the applicable vesting dates. Vesting rights generally cease upon termination of employment and exercise rights cease shortly after termination, except that exercisability is extended in the case of death or disability. In the event of a change of control, the Compensation Committee will determine whether the equity incentive awards that replaced the existing options were of equivalent value, the options will be cancelled and holders will continue holding the awards for which the options were replaced. If outstanding options are not replaced by another form of equity incentive award, or are replaced by awards that the Compensation Committee determines are not of sufficient value, then vesting may be fully accelerated upon a change of control. Prior to the exercise of an option, the holder has no rights as a shareholder with respect to the shares subject to such option, including no voting rights and no right to receive dividends or dividend equivalents.

The Somaiya Agreement provided for the initial grant of 824,697 options to purchase ordinary shares, with 25% vesting on the first anniversary of the grant date and with the remaining shares vesting in equal monthly installments thereafter for three years. Mr. Somaiya is also eligible to participate in our equity incentive plans, including the LTIP, and other employee benefits and insurance programs generally made available to our full-time U.S.-based executives.

In the event Mr. Somaiya’s employment is terminated by the Company without Cause or by Mr. Somaiya for Good Reason (if termination is requested by a third party) within three months prior to a Change in Control (as defined in the Somaiya Agreement) or during the 12 months following such Change in Control, Mr. Somaiya will be entitled to receive the severance payments and benefits described above. In addition, all of Mr. Somaiya’s

26

time-based stock options and equity awards will accelerate, becoming fully exercisable and nonforfeitable as of the termination date and the exercise period for certain vested options will be extended.

Mr. Somaiya is also party to a Confidentiality and Assignment of Inventions Agreement, which includes certain customary non-competition, non-solicitation, confidentiality and assignment of inventions obligations in favor of the Company.

Outstanding Equity Awards at 2023 Fiscal Year-End

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

Equity Incentive Plans

LTIP

We have established the 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, 2023 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 Agreement or as replacement awards in connection with a merger or business combination) will not exceed 13,649,090; 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 or directors 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 changes in control.

27

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.

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 of 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 or directors 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 of 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:

28

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.

Role of our Compensation Committee, Management and Consultants

Compensation Committee

Our Compensation Committee is responsible for reviewing, evaluating, approving, administering and interpreting our executive compensation and benefits policies, programs and plans, including the LTIP, Rollover Plan and Supplementary LTIP. In particular, with respect to the compensation of our named executive officers, our Compensation Committee is responsible for reviewing and recommending to the Board of Directors the compensation levels and performance goals relevant to the compensation of these officers, and for evaluating the officers’ performance in light of those goals and objectives, if any. The Board of Directors approved the Compensation Committee’s recommendations for the 2023 compensation of our named executive officers. The Compensation Committee may delegate its authority to a subcommittee or its chairperson.

Management

Our Chief Executive Officer works with our Compensation Committee and compensation consultants to design and develop our executive compensation programs for consideration by the Compensation Committee and ultimately, to implement the decisions of the Compensation Committee.

The Chief Executive Officer recommends to the Compensation Committee for its discussion and ultimately, approval, proposed compensation levels and structures, and provides input on the objectives of the compensation plan. For executives other than the Chief Executive Officer, the Compensation Committee will consider the individual performance of the executives, as assessed by the Chief Executive Officer, and the compensation recommendations submitted to the Compensation Committee by the Chief Executive Officer. The Board of Directors has delegated to Dr. Davidson the authority to grant awards under the LTIP and Supplementary LTIP to any eligible individual other than our directors or executive officers.

Consultants

In 2023, the Compensation Committee engaged an independent external consultant, Aon’s Human Capital Solutions Practice, a division of Aon plc (“Aon”), to advise on overall compensation matters for all employees, including our named executive officers, and non-employee members of our Board of Directors. As part of its duties, Aon provided the Compensation Committee with the following services:

29

While Aon works with management to source market data and to arrive at market matches for new hires and promotions of executive officers, Aon reports directly to the Compensation Committee. Aon consultants attend meetings of the Compensation Committee when requested to do so. The Compensation Committee has assessed the independence of Aon pursuant to SEC and Nasdaq rules. In doing so, the Compensation Committee considered each of the factors set forth by the SEC and the Nasdaq with respect to a compensation consultant’s independence. The Compensation Committee also considered the nature and amount of work performed for the Compensation Committee and the fees paid for those services in relation to the firm’s total revenues. Based on its consideration of the foregoing and other relevant factors, the Compensation Committee concluded that there were no conflicts of interest, and that Aon is independent.

Trading Policy

We have a policy that prohibits our executive officers, directors and other employees from engaging in short sales, transactions in put or call options, pledging transactions, hedging transactions or other inherently speculative transactions with respect to our shares. Any violation of these policies may result in disciplinary action, including dismissal for cause.

Compensation Clawback Policy

We maintain a clawback policy (the “Clawback Policy”) in compliance with the SEC’s and Nasdaq Stock Market, LLC’s (“Nasdaq”) final rules. The Clawback Policy requires the repayment of certain erroneously awarded incentive-based compensation paid to any current or former executive officer, including our named executive officers, in connection with a restatement of financial statements if such compensation exceeds the amount that the executive officers would have received based on the restated financial statements.

30

DIRECTOR COMPENSATION

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 $40,000. Non-employee directors may receive further compensation ranging from $5,000 to $15,000 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-executive directors during the year ended December 31, 2023. We reimburse members of the Board of Directors for reasonable travel and out-of-pocket expenses incurred in connection with attending meetings of the Board of Directors and committees.

31

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 eight 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, Dr. Lange and Mr. Slootweg 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 serves as the Chair 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

32

in determining their independence, including the beneficial ownership of our capital stock by each director.

Nasdaq Board Diversity Matrix

Board Diversity Matrix (As of April 15, 2024)

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.

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 eight 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, Dr. Lange and Mr. Slootweg, 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 of age, race, gender, sexual orientation, geography, ethnicity, thought, viewpoints, backgrounds, skills, experience, and expertise. As a result, under our policies any search firm retained to assist the Nomination

35

and Corporate Governance Committee in seeking candidates for the Board of Directors will be instructed to seek to include diverse candidates in terms of age, race, gender, sexual orientation, geography, ethnicity, thought,

viewpoints, backgrounds, skills, experience, and expertise from, among other areas, the traditional corporate environment, government, academia, private enterprise, non-profit organizations, and professions such as accounting, finance, marketing, human resources, and legal services. 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 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.

36

Code of Business Conduct and Ethics

We have adopted a code of business conduct and ethics which outlines the principles of legal and ethical business conduct under which we will do business. The code of business conduct and ethics includes a provision that

provides for a process by which employees and directors can report potential irregularities. The code of business conduct and ethics also provides protection from retaliation or discrimination by the Company against whistleblowers due to reporting issues relating to compliance with applicable laws and regulations. This code applies to all of our employees, officers and directors. Our code of business conduct and ethics is available on our website.

Corporate Governance Documents

Please visit our corporate governance overview website at https://ir.newamsterdampharma.com/corporate-governance/governance-overview for additional information on our corporate governance, including:

In the event of any amendment to, or waiver from, a provision of our code of business conduct and ethics, we will promptly post on our website relevant information regarding the amendment or waiver, including the date and the nature of the event. Our website and its contents are not incorporated into this proxy statement.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee consists of Louis Lange, M.D., Ph.D., John W. Smither, Janneke van der Kamp and William H. Lewis. All members of the Compensation Committee are independent directors, and none of our executive officers or former executive officers served on the compensation committee or on the board of any company that employed any member of the Compensation Committee or the Board of Directors during the year ended December 31, 2023.

Report of the Audit Committee

The Audit Committee reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2023 with management of the Company. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and the SEC. The Audit Committee also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 that was filed with the SEC on February 28, 2024.

The following table sets forth certain information as of December 31, 2023 with respect to our LTIP, Rollover Plan and Supplementary LTIP:

39

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

40

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” section of this proxy statement for a further discussion of these arrangements.

41

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, 2024, 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.

The beneficial ownership of Ordinary Shares is based on 89,912,552 Ordinary Shares issued and outstanding, as of April 15, 2024. 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.

42

Forbion IV Management B.V. (“Forbion IV Management”) may be deemed to have voting and dispositive power over the Ordinary Shares beneficially owned by Forbion IV. Investment decisions with respect to the

43

Ordinary Shares held by Forbion IV are made by its investment committee which may delegate such powers to the authorized representatives of Forbion IV Management. Mssrs. Slootweg, van Osch, Mulder, van Houten, van Deventer, Reithinger, Kersten and Boorsma are partners of Forbion IV Management, which is the director of and acts as the investment advisor to Forbion IV.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires the Company’s executive officers and directors, and persons who own more than 10% of our ordinary shares, to file reports of ownership and changes in ownership with the SEC. Executive officers, directors, and greater than 10% shareholders are required by regulation to furnish the Company with copies of all Section 16(a) reports they file.

Based solely on a review of such reports filed electronically with the SEC, and written representations provided to the Company from the individuals required to file the reports, the Company believes that each of its executive officers and directors has complied with Section 16(a) filing requirements for transactions in our ordinary shares during the year ended December 31, 2023, except for (i) Form 3s filed by each of Louis Lange and Michael Davidson in December 2023 to report their initial beneficial ownership of shares and which inadvertently omitted certain securities which were subsequently disclosed on a Form 3 amendment filed on January 25, 2024 and (ii) a late Form 4 filed by Louis Lange on February 21, 2024 to report the acquisition of ordinary shares.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to satisfy the delivery requirements for proxy materials with respect to two or more shareholders sharing the same address by delivering a single set of proxy materials addressed to those shareholders sharing the same address. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for companies.

To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple shareholders who share an address, unless we received contrary instructions from the impacted shareholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any shareholder at the shared address to which a single copy of those documents was delivered. If your household received a single set of proxy materials this year, but you would prefer to receive your own copy, or if you currently share an address with another shareholder and wish to receive only one copy of proxy materials in future for your household, please contact Broadridge Householding Department, by calling their toll free number, 1-866-540-7095 or by writing to: Broadridge, Householding Department, 51 Mercedes Way, Edgewood, NY 11717. If you have requested to be removed from the householding program, you will be removed within 30 days of receipt of your instructions at which time you will then be sent separate copies of the documents.
