The General Meeting of Shareholders (the “General Meeting”) of ATAI Life Sciences N.V., a public limited liability company (naamloze vennootschap) incorporated under the laws of the Netherlands (the “Company”), will be held at 6:00 p.m. (Central European Summer Time) on October 13, 2022. Our General Meeting will be a “hybrid” meeting of shareholders, meaning that you may attend the meeting either via the Internet at www.virtualshareholdermeeting.com/ATAI2022SM by following the instructions set forth below or in person in Amsterdam, The Netherlands. We believe this virtual attendance alternative enables increased shareholder participation from locations around the world.

We recommend that you log in a few minutes before the meeting to ensure you are logged in when the meeting starts.

Shareholders may attend the meeting either virtually, by visiting www.virtualshareholdermeeting.com/

The agenda for the General Meeting is as follows:

No business shall be voted on at the General Meeting, except such items as included in the above-mentioned agenda.

The record date for the General Meeting in respect of our common shares is September 15, 2022 (the “Record Date”). Those who are holders of our common shares in the capital, or who otherwise have voting rights and/or meeting rights with respect to our common shares, on the Record Date, provided that they are recorded as such in the register maintained by our U.S. transfer agent, may virtually attend and, if relevant, vote prior to the General Meeting (the “Persons with Meeting Rights”).

Persons with Meeting Rights who wish to attend the General Meeting, virtually or in person, or be represented by proxy, must notify us of their identity and intention to attend the General Meeting by e-mail (addressed to annualmeeting@atai.life) or in writing (addressed to ATAI Life Sciences N.V., Corporate Secretary, Wallstraße 16, 10179 Berlin, Germany). This notice must be received by us no later than 5:00 p.m. (Central European Summer Time) on October 11, 2022 (the “Cut-off Time”). Persons with Meeting Rights who have not complied with this requirement may be refused attendance at the General Meeting. Persons with Meeting Rights may have themselves represented at the General Meeting through the use of a written or electronically recorded proxy. Proxyholders who wish to attend the General Meeting should present a copy of their proxy upon entry to

the General Meeting, failing which the proxyholder concerned may be refused entry to the General Meeting. A proxy form for this purpose can be downloaded from our website (www.atai.life).

It is important that your shares be represented, regardless of the number of shares you may hold. We urge you vote your shares or to submit your proxy. Proxies may be submitted prior to the Cut-off Time via a toll-free telephone number (call 1-800-690-6903) or over the Internet (visit www.proxyvote.com), as described in further detail in the enclosed materials, or by signing, dating and mailing the proxy card in the enclosed return envelope or emailing the signed and dated proxy card to annualmeeting@atai.life. Voting your shares or submitting your proxy, as applicable, will be important for the presence of a quorum at the General Meeting and will save us the expense of further solicitation. Submitting a proxy will not prevent you from voting your shares at the General Meeting if you desire to do so, as your proxy is revocable at your option.

At the General Meeting, each of the following proposals (the “Proposals”) will be on the agenda as a voting item:

No business shall be voted on at the General Meeting, except for the Proposals.

The supervisory board recommends that you vote your shares FOR all Proposals. If you properly submit your proxy, your common shares will be voted on your behalf as you direct. If not otherwise specified, the common shares represented by the proxies received prior to 5:00 p.m. (Central European Summer Time) on October 11, 2022 will be voted FOR all Proposals.

Why you received this proxy statement. You have received these proxy materials because atai’s supervisory board is soliciting your proxy to vote your shares at the General Meeting. This proxy statement includes information that we are required to provide to you under the rules of the SEC and that is designed to assist you in voting your shares.

Proxy Card. Instructions regarding how you can vote are contained on the proxy card included with these materials.

Householding. The SEC’s rules permit us to deliver a single set of proxy materials to one address shared by two or more of our shareholders. This delivery method is referred to as “householding” and can result in significant cost savings. 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 you prefer to receive separate copies of the proxy statement or annual report, contact Broadridge Financial Solutions, Inc. by calling 1-866-540-7095 or in writing at 51 Mercedes Way, Edgewood, New York 11717, Attention: Householding Department. In addition, if you currently are a shareholder who shares an address with another shareholder and would like to receive only one copy of future notices and proxy materials for your household, you may notify your broker if your shares are held in a brokerage account or you may notify us if you hold registered shares. Registered shareholders may notify us by contacting Broadridge Financial Solutions, Inc. at the above telephone number or address.

The Record Date for the General Meeting is September 15, 2022. Persons with Meeting Rights (i.e., holders of common shares or who otherwise have voting rights and/or meeting rights with respect to common shares on the Record Date, provided that they are recorded as such in the register maintained by our U.S. transfer agent) may attend and vote at the General Meeting. Each outstanding common share is entitled to one vote on all matters presented at the General Meeting as voting items. At the close of business on September 15, 2022, there were approximately 165,875,307 common shares outstanding.

A record holder holds shares in his or her name. Shares held in “street name” means shares that are held in the name of a bank or broker on a person’s behalf.

Yes. If your shares are held by a bank or a brokerage firm, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, these proxy materials will be provided to you by your bank or brokerage firm, along with a voting instruction card. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. If your shares are held in street name, you may not be able to vote your shares during the General Meeting unless you obtain a legal proxy from your bank or brokerage firm.

A quorum must be present at the General Meeting for any proposal to be voted on. At the General Meeting, at least one-third of the Company’s issued and outstanding common shares must be present or represented in order to constitute a quorum for Proposals 1 through 3.

The General Meeting will be held at 6:00 p.m. (Central European Summer Time) on Thursday, October 13, 2022. Shareholders may attend the meeting either virtually, by visiting www.virtualshareholdermeeting.com/ATAI2022SM and entering your 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials, or in person at Dentons Europe LLP, Gustav Mahlerplein 2, Amsterdam 1082 MA, The Netherlands.

You may attend the General Meeting if you are a Person with Meeting Rights (see above under “Who is entitled to vote prior to the General Meeting”), or if you hold a valid proxy from a Person with Meeting Rights for the General Meeting. If you would like to attend the General Meeting, or be represented by proxy, you must notify us by e-mail (addressed to annualmeeting@atai.life) or in writing (addressed to ATAI Life Sciences N.V., Corporate Secretary, Wallstraße 16, 10179 Berlin, Germany) of your identity and intention to attend the General Meeting. This notice must be received by us no later than 5:00 p.m. (Central European Summer Time) on October 11, 2022 (the “Cut-off Time”). If you do not comply with this requirement, you may be refused attendance of the General Meeting.

Proxyholders who wish to attend the General Meeting should also present a copy of their proxy by e-mail (addressed to annualmeeting@atai.life) or in writing (addressed to ATAI Life Sciences N.V., Corporate Secretary, Wallstraße 16, 10179 Berlin, Germany) prior to the Cut-off Time, failing which the proxyholder concerned may be refused attendance of the General Meeting.

If your bank or broker holds your shares in street name, you may also be required to provide proof of beneficial ownership of our common shares on the Record Date, such as a bank or brokerage statement or a letter from your bank or broker showing that you owned our common shares at the close of business on the Record Date.

You may virtually attend and participate in the General Meeting by visiting www.virtualshareholdermeeting.com/ ATAI2022SM. The meeting webcast will begin promptly at 6:00 p.m. (Central European Summer Time). We encourage you to access the meeting prior to the start time. Online check-in will begin at 5:55 p.m. (Central European Summer Time), and you should allow ample time for the check-in procedures. To virtually attend and participate in the General Meeting, you will need the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials. If your bank or broker holds your shares in street name, you should contact your bank or broker to obtain your 16-digit control number. If you lose your 16-digit control number, you may join the General Meeting as a “Guest” but you will not be able to ask questions.

We will have IT personnel ready to assist you with any technical difficulties you may have accessing the virtual meeting website. If you encounter any difficulties accessing the virtual meeting website during the check-in or meeting time, please call the technical support number that will be posted on the General Meeting login page.

Yes, our supervisory directors are expected to attend the General Meeting. In light of the fact that we will be holding a hybrid General Meeting this year, we expect that some or all of our supervisory directors may virtually attend the General Meeting.

If the requisite quorum (see above under “How many shares must be present to hold the General Meeting”) is not present, then the General Meeting cannot validly pass any of the voting items on the agenda for the General Meeting and a new meeting shall be convened in accordance with applicable law.

It means that your common shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each set of proxy materials please submit your proxy by phone, via the Internet, by signing, dating and returning the enclosed proxy card in the enclosed envelope or via email.

Shareholders of Record – If you are a shareholder of record, you have the right to vote online or in person at the General Meeting or you may appoint a proxy to vote on your behalf. All proxies must be received no later than the Cut-off Time. There are four ways to vote by proxy:

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

Submitting a proxy will not prevent you from voting your shares at the General Meeting if you desire to do so, as your proxy is revocable at your option.

Beneficial Owners of Shares Held in “Street Name” – If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from your bank or broker. You must follow their instructions in order for your shares to be voted. Telephone and Internet voting also may be offered to shareholders owning shares through certain banks and brokers.

If your shares are held in street name and you would like to vote your shares in person at the General Meeting, you should contact your bank or broker to obtain a legal proxy, bring it to the General Meeting in order to vote and notify us in writing of your identity and intention to attend the General Meeting (see above under “Who can attend the General Meeting?”).

Yes. You may revoke your submitted proxy and change your vote prior to the time of voting at the General Meeting by:

Your most recent proxy card or telephone or Internet proxy is the one that will be counted. You may also attend the 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 General Meeting in person and revoke your prior proxy at the meeting on your behalf.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote in person at the General Meeting by obtaining a legal proxy from your bank or broker, bringing your legal proxy to the General Meeting in order to vote and notifying the Company in writing of your identity and intention to attend the General Meeting (see above under “Who can attend the General Meeting?”).

If you submit a proxy prior to the Cut-Off Time but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the supervisory board. The supervisory board’s recommendations are indicated on page 4 of this proxy statement, as well as with the description of each proposal in this proxy statement.

Broadridge Financial Solutions, Inc. will tabulate the votes submitted by proxy prior to the Cut-off Time as described in this proxy statement. This tabulation will be provided to the Company. Votes cast at the General Meeting by Persons with Meeting Rights attending in person shall be tabulated by a civil law notary of Dentons Europe LLP, our Dutch legal counsel (or a substitute).

No business shall be voted on at the General Meeting, except such items as included in the agenda for the meeting included on page 1 of this proxy statement.

Other than the proposal to appoint Stephen Bardin, each voting item on the agenda for the General Meeting requires the affirmative vote of a simple majority of the valid votes cast. Proposal 3 to appoint Stephen Bardin as a managing director is based on a binding nomination proposed by the supervisory board. The proposed candidate specified in a binding nomination shall be appointed provided that the requisite quorum is present or represented at the General Meeting, unless the nomination is overruled by the General Meeting, which would result if at least a two-thirds of the votes cast, representing more than half of the Company’s issued share capital, vote against the appointment.

An “abstention” represents a shareholder’s affirmative choice to decline to vote on a proposal. Under Dutch law and our articles of association, shares abstaining from voting will not count as votes cast at the General Meeting, but will count as shares present and entitled to vote for purposes of determining a quorum. Abstentions have no effect on the proposals.

Each shareholder present in person, virtually or by proxy or, in the case of a corporation, by a duly authorized representative, has one vote for each share held by the shareholder.

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker has not received voting instructions from the beneficial owner and lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the appointment of our independent registered public accounting firm, without instructions from the beneficial owner of those shares, in which case your shares will count for purposes of determining whether a quorum is present. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the appointment of directors. Broker non-votes have no effect on the 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.

We will solicit proxies and will bear the entire cost of this solicitation. The initial solicitation of proxies may be supplemented by additional mail communications and by telephone, fax, email, Internet and personal solicitation by our supervisory directors, managing directors or other employees. No additional compensation for soliciting proxies will be paid to our supervisory directors, managing directors or other employees for their proxy solicitation efforts.

We plan to announce whether the proposals have passed at the General Meeting and we will report the final voting results in a Current Report on Form 8-K, which we intend to file with the SEC after the General Meeting.

Our supervisory board (raad van commissarissen) is composed of seven members, whom we refer to as our supervisory directors. Each supervisory director holds office for the term set by our general meeting (as set forth in the table below), except in the case of his or her earlier death, resignation or removal. Our supervisory directors do not have a retirement age requirement under our articles of association.

The following table sets forth the names and functions of our supervisory directors, their ages, term served and the year of expiration of their term as supervisory directors:

Our general meeting of shareholders may overrule the binding nomination by a resolution passed by a two-thirds majority of votes cast, provided such majority represents more than half of our issued share capital, in which case our supervisory board shall be allowed to make a new binding nomination. Our supervisory directors may be dismissed only by a resolution at a general meeting of shareholders. Dismissal of a supervisory director by our general meeting of shareholders requires a two-thirds majority of votes cast, provided such majority represents more than half of our issued share capital, unless the dismissal is proposed by the supervisory board, in which latter case a simple majority of votes cast will suffice to pass the resolution.

All of our supervisory directors, other than Christian Angermayer, qualify as “independent” in accordance with Nasdaq listing requirements. The Nasdaq independence definition includes a series of objective tests, including that the supervisory director is not, and has not been for at least three years, one of our employees and that neither the supervisory director nor any of his or her family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our supervisory board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of our supervisory board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a supervisory director. In making these determinations, our supervisory board reviewed and discussed information provided by the supervisory directors and us with regard to each supervisory director’s business and personal activities and relationships as they may relate to us and our management. Mr. Angermayer is not independent because he is the founder of Apeiron Investment Group Ltd., one of our principal shareholders.

The nominating committee is responsible for drawing up selection criteria and appointment procedures for the supervisory directors. In searching for qualified supervisory director candidates for appointment to the supervisory board and filling vacancies on the supervisory board, the nominating committee may solicit current supervisory directors and our executives for the names of potentially qualified candidates or ask supervisory directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The nominating committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider supervisory director candidates recommended by our shareholders. Once potential candidates are identified, the nominating committee reviews the backgrounds of those candidates, evaluates candidates’ independence from us and potential conflicts of interest and determines if candidates meet the qualifications desired by the nominating committee for candidates for appointment as a supervisory director.

In evaluating the suitability of individual candidates (both new candidates and current supervisory board members), the nominating committee, in recommending candidates for appointment, and the supervisory board, in approving (and, in the case of vacancies, appointing), may take into account many factors, including: personal and professional integrity, ethics and values; experience in corporate management, such as serving as an officer or former officer of a publicly held company; strong finance experience; experience relevant to our industry;

experience as a board member or executive officer of another publicly held company; experience relevant to an international company; relevant academic expertise or other proficiency in an area of our operations; diversity of expertise and experience in substantive matters pertaining to our business relative to other board members; diversity of background and perspective, including, but not limited to, with respect to age, gender, ethnicity and specialized experience; practical and mature business judgment, including, but not limited to, the ability to make independent analytical inquiries; and any other relevant qualifications, attributes or skills. The supervisory board evaluates each individual in the context of the supervisory board, with the objective of assembling a group that can best perpetuate the long-term success and sustainability of the business and further the interests of our stakeholders, including shareholders, through the exercise of sound judgment using its diversity of experience in these various areas. In determining whether to recommend a supervisory director for re-appointment, the nominating committee may also consider the director’s past attendance at meetings and participation in and contributions to the activities of the supervisory board.

Shareholders may recommend individuals to our nominating committee for consideration as potential supervisory director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to our nominating committee, c/o Corporate Secretary at corpsec@atai.life. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the committee will evaluate shareholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others. Shareholders who desire to nominate persons directly for election to the supervisory board at an annual general meeting of shareholders must meet the deadlines and other requirements set forth under “Shareholder Proposals.”

The supervisory board will give appropriate attention to written communications that are submitted by shareholders, and will respond if and as appropriate. Our Corporate Secretary and General Counsel are primarily responsible for monitoring communications from shareholders and for providing copies or summaries to the supervisory directors as they consider appropriate.

Communications deemed to comply with our policy regarding shareholder communications with the board of supervisory directors and are deemed appropriate are forwarded to our supervisory directors on a periodic basis, generally in advance of each regularly scheduled meeting of the supervisory board. Shareholders who wish to send communications on any topic to the board of supervisory directors, the management board, the chairman of the supervisory board, any chairman of a supervisory board committee, or the lead independent supervisory director should address such communications to the intended recipient by name or position in case of: Corporate Secretary at corpsec@atai.life.

Our supervisory board is comprised of individuals with extensive experience with life sciences industries. Our management board and key employees are charged primarily with our day-to-day business and operations and the implementation of our strategy. Our supervisory directors are charged primarily with the supervision of the performance of the duties of our supervisory board.

Under the Rules of the Board of Supervisory Directors, if the chairperson of the supervisory board does not qualify as independent, the independent directors may elect a lead independent supervisory director, who we refer to as our lead director. The lead director’s responsibilities include presiding over all meetings of the supervisory board at which the chairperson is not present, including any executive sessions of the independent directors; approving supervisory board meeting schedules and agendas; and acting as the liaison between the independent directors and the chief executive officer and chairperson of the supervisory board. At such times as the chairperson of the supervisory board is an independent director, the chairperson will serve as lead director.

In light of the fact that Mr. Angermayer serves as chairman, in September 2021 the supervisory board appointed Michael Auerbach to serve as lead director. Mr. Auerbach 's qualifications to serve as our lead director include his strong leadership experience as the founder and General Partner of Subversive Capital since 2013 and as Senior Vice President at Albright Stonebridge Group, a global consulting firm chaired by former Secretary of State Madeleine Albright.

Our supervisory board believes that this leadership structure, coupled with a commitment to board independence, provides effective independent oversight of management. Our supervisory board has concluded that our current leadership structure is appropriate at this time. However, our supervisory board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate. Risk assessment and oversight are an integral part of our governance and management processes.

Our supervisory board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the supervisory board at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our supervisory board does not have a standing risk management committee, but rather administers this oversight function directly through the supervisory board as a whole, as well as through various standing committees of the supervisory board that address risks inherent in their respective areas of oversight. In particular, our supervisory board is responsible for monitoring and assessing strategic risk exposure, including with respect to business continuity risks such as risks relating to the COVID-19 pandemic, and our audit committee is charged with overseeing the responsibilities of our supervisory board with respect to the application of information and communication technology by us, including risks relating to cybersecurity. The audit committee also periodically reviews our policies and procedures for reviewing and approving or ratifying “related person transactions” (defined as transactions required to be disclosed pursuant to Item 404 of Regulation S-K), including our related person transaction policy, and recommends any changes to our supervisory board, and in accordance with our related person transaction policy and the Nasdaq rules, our audit committee conducts appropriate review and oversight of all related person transactions for potential conflict of interest situations on an ongoing basis. Our nominating committee manages the risk associated with the independence of the supervisory board and potential conflicts of interest and oversees our efforts with regard to environmental, social and governance matters and associated risks. Our compensation committee oversees the management of risk relating to our incentive compensation and equity-based plans and arrangements, and is charged with submitting clear and understandable proposals to our supervisory board concerning changes to our compensation policies. The supervisory board does not believe that its role in the oversight of our risks adversely affects the board’s leadership.

Under the Rules of the Board of Supervisory Directors, an annual assessment of the supervisory board and its committees is required and the nominating committee charter requires the nominating committee to oversee such annual assessment.

We have adopted a written Code of Conduct that applies to our supervisory directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and others temporarily assigned to perform work or services for us. We have posted a current copy of the Code Conduct on our website, www.atai.life. Our supervisory board is responsible for administering the Code of Conduct. The supervisory board is allowed to amend, alter or terminate the Code of Conduct. In addition, we intend to post on our website all disclosures that are required by law or the Nasdaq rules concerning any amendments to, or waivers from, any provision of the Code of Conduct. We did not grant any waivers in 2021.

Our supervisory board has adopted an Insider Trading Compliance Policy, which applies to all of our supervisory directors, officers and employees. The policy prohibits our directors, officers and employees and any entities they control from purchasing financial instruments, such as prepaid variable forward contracts, equity swaps, collars and exchange funds, or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities, or that may cause an officer, director or employee to no longer have the same objectives as our other shareholders.

There were four meetings of the supervisory board during fiscal year 2021. During fiscal year 2021, each director attended at least 75% of the aggregate of all meetings of the supervisory board and meetings of the committees on which the director served during the period in which he or she served as a director.

Currently, we do not maintain a formal policy regarding director attendance at the Annual General Meeting.

Our supervisory board has established audit, compensation and nominating committees — each of which operates under a written charter that has been approved by our supervisory board and that is available in the Investors section of our website at www.atai.life. All of the members of each of these committees are independent as defined under the Nasdaq rules. Our supervisory board has determined that Sabrina Martucci Johnson, Alexis de Rosnay and Andrea Heslin Smiley meet the independence requirements of Rule 10A-3 under the Exchange Act for purposes of serving on the audit committee. All members of the compensation committee meet the heightened standard for independence specific to members of a compensation committee under the Nasdaq rules and each qualifies as a “non-employee director” as defined in Rule 16b-3 of the Exchange Act. All members of the nominating committee are independent under the Nasdaq rules.

The members and chairpersons of our audit, compensation and nominating committees are set forth in the following table. Neither Christian Angermayer nor Jason Camm serve on any of these committees.

Our audit committee’s duties and responsibilities include:

The members of the audit committee are Ms. Johnson, Mr. de Rosnay (who serves as chairman of the audit committee) and Ms. Smiley. The members of our audit committee meet the requirements for financial literacy under the applicable rules of Nasdaq. Our supervisory board has determined that Mr. de Rosnay is an “audit committee financial expert” as defined by Item 407(d)(5)(ii) of Regulation S-K.

The audit committee meets as often as one or more members of the audit committee deem necessary, but in any event, meets at least four times per year. The audit committee meets at least once per year with our independent accountant, without our management being present. The audit committee met five times in 2021.

Our compensation committee is responsible for assisting the supervisory board in the discharge of its responsibilities relating to the compensation of our senior management, including our management board and key employees. In fulfilling its purpose, our compensation committee has the following principal duties:

The compensation committee has the authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors to assist in carrying out its responsibilities, including being directly responsible for the appointment, oversight and compensation of such consultant, counsel or advisor and the ability to cause us, without further action by the supervisory board, to pay the compensation of such consultant, counsel or advisor as approved by the compensation committee, provided, however, that in retaining or obtaining the advice of such consultant, counsel or advisor, other than in-house legal counsel, the compensation committee shall take into consideration the factors affecting independence required by applicable SEC and Nasdaq rules. The compensation committee also has the authority to conduct or authorize investigations into any matters within the scope of its responsibilities as it shall deem appropriate, including the authority to request any officer, employee or advisor of us to meet with the compensation committee or any advisors engaged by the compensation committee. During 2021, the compensation committee engaged Radford, which is part of the Rewards solutions practice at Aon plc. The compensation committee reviewed compensation assessments provided by Radford comparing our compensation to that of a group of peer companies within our industry and met with Radford to discuss compensation of our management board and key employees and to receive input and advice. The compensation committee reviewed legal matters related to the form of compensation of our management board and key employees and the employment contracts associated with these officers. The compensation committee has considered the independence of its advisors and found them to be so according to the adviser independence factors required under SEC rules as they relate to (i) additional services, (ii) total fees as a percentage of total revenue, (iii) conflict of interest policies, (iv) business or personal relationships with members of the compensation committee, (v) stock ownership by compensation advisors and (vi) business or personal relationships with our executives.

The members of our compensation committee are Messrs. Auerbach and de Rosnay and Ms. Smiley (who serves as chair of the compensation committee). The compensation committee met two times during 2021.

Our nominating committee’s responsibilities include:

The members of our nomination and corporate governance committee are Ms. Smiley, Mr. Kalali and Ms. Johnson (who serves as chair of the nominating committee). The members of the nominating committee met two times during 2021.

Section 16(a) of the Exchange Act requires our supervisory directors, executive officers and persons beneficially owning more than 10% of any class of our common shares registered pursuant to Section 12 of the Exchange Act (collectively, the “Reporting Persons”) to file initial statements of beneficial ownership of our common shares and statements of changes in beneficial ownership of our common shares with the SEC. To our knowledge, based solely on our review of the copies of such forms filed with the SEC and upon written representations of the Reporting Persons received by us, all of these filing requirements were timely satisfied in 2021 and that there has been a late Form 4 filing in January 2022 for Michael Auerbach reporting one transaction one day late, due to an administrative delay by a third-party vendor.

In January 2021, pursuant to an additional closing under our Series C financing, we issued an additional 2,133,328 Series C shares of ATAI Life Sciences AG at a purchase price of €4.69 per share, for an aggregate purchase price of €9,999,975.

The following table summarizes purchases of our Series C shares by related parties pursuant to the additional closing:

In March 2021, Galaxy Group Investments LLC, one of our principal shareholders, purchased 100,000 convertible notes from Apeiron. On September 17, 2021, Galaxy exercised all of their convertible notes for a total payment to us of €17.0 million and was issued 1.6 million common shares.

On January 16, 2021, we entered into a consulting agreement with Christian Angermayer, one of our co-founders and chairman of our board of supervisory directors. Pursuant to the consulting agreement, Mr. Angermayer has agreed to render certain services to us, including advising on the structure and timing of our initial public offering in June 2021 and on business and financing strategies generally. In exchange for the services provided by Mr. Angermayer, and upon the achievement of certain performance targets, he was allocated 624,000 options under our 2020 Plan, each option exercisable for €4.69 into one of our common shares. The consulting agreement expires on March 31, 2024. The options granted to Mr. Angermayer are subject to his continued services through the date of exercise.

Apeiron is Mr. Angermayer’s family office. As of September 6, 2022, Apeiron held a 19.3% interest in us.

In connection with our initial public offering in June 2021, the underwriters reserved a portion of the common shares for sale to our managing directors, supervisory directors and others. Under the directed share

program, Apeiron purchased 700,000 common shares for $10.5 million. Apeiron is Mr. Angermayer’s family office. As of September 6, 2022, Apeiron held a 19.3% interest in us.

Our articles of association require us to indemnify our current and former managing directors and supervisory directors to the fullest extent permitted by law, subject to certain exceptions. We have entered into indemnification agreements with all our managing directors and supervisory directors.

We have entered into employment agreements with some of our managing directors, as discussed in more detail within “Executive Compensation — Executive Employment Agreements.”

Our supervisory board adopted a related person transaction policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. Under the policy, our legal team is primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances, whether such potential related person transactions do, in fact, constitute related person transactions requiring compliance with our policy. A related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which the Company and any related person are, were or will be participants in which the amount involved exceeds $120,000. Pursuant to the policy, transactions involving (i) compensation to an executive officer, member of the management board or member of the supervisory board, if such compensation is required to be reported in our proxy statement and has been approved by the supervisory board or remuneration committee of the supervisory board, (ii) compensation for services provided to the Company as an executive officer who is not an immediate family member of a related person if the executive officer was a named executive officer in the proxy statement and such remuneration has been approved, or recommended to the supervisory board for approval, by the compensation committee of the supervisory board, and (iii) certain ordinary course of business transactions have been pre-approved by the Audit Committee. A related person is any executive officer, director or beneficial owner of more than 5% of any class of our voting securities and any of their respective immediate family members and any entity owned or controlled by such persons.

Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our general counsel must present information regarding the related person transaction to the audit committee, for review, consideration and approval or ratification. The presentation must include a description of, among other things, all relevant facts and circumstances relating thereto. Under the policy, we will collect information that we deem reasonably necessary from each director, executive officer and, to the extent feasible, significant shareholder to enable us to identify any existing or potential related-person transactions and to effectuate the terms of the policy. In considering related person transactions, our audit committee will take into account the relevant available facts and circumstances including, but not limited to:

Following the end of each year, our supervisory board determines the bonus amounts for our executives, including our named executive officers. For 2021, the supervisory board determined to award bonuses for all employees, including our named executive officers, at 100% of target based upon the company’s overall positive performance for the year, including the successful launch of our initial public offering.

The bonuses awarded to our named executive officers for 2021 performance are set forth above in the 2021 Summary Compensation Table in the column entitled “Bonus.”

Our named executive officers have been granted options to purchase our common shares. Options typically vest as to 25% of the shares subject to the option on the first anniversary of the applicable vesting commencement date and as to the remaining 75% of the shares subject to the option in 36 substantially equal monthly installments thereafter until the fourth anniversary of the vesting commencement date, subject to accelerated vesting upon a change in control or in the event the named executive officer’s service with the company is terminated due to his death or disability. Certain options granted to our named executive officers have been granted with performance-based vesting conditions. Options granted prior to our initial public offering were not exercisable prior to (1) the fourth anniversary of the date of grant and (2) the occurrence of a liquidity event, subject, in each case, to continued service through such date. Following our initial public offering, these conditions to exercisability are no longer applicable.

The following table sets forth the aggregate number of options granted to our named executive officers during 2021.

Refer to the “Outstanding Equity Awards at Fiscal Year End” table below for information regarding the vesting schedules of these awards.

In January 2021, the board approved accelerated vesting of outstanding options granted under our 2020 Employee, Director and Consultant Equity Plan (the “2020 Plan”) and HSOP Shares (as defined below) such that the vesting schedule of awards outstanding prior to our initial public offering accelerated by 25%.

In connection with our initial public offering, we adopted the 2021 Incentive Award Plan (the “2021 Plan”) in order to facilitate the grant of cash and equity incentives to our supervisory and management board directors, employees (including our named executive officers) and consultants and certain of our affiliates. We ceased granting awards under the 2020 Plan when the 2021 Plan became effective.

In January 2021, Mr. Brand was granted 4,906,400 shares under a Hurdle Share Option Program, or the HSOP. We refer to these shares as “HSOP Shares”. Upon allocation, Mr. Brand paid the nominal value of €0.06 per share for each HSOP Share. The strike price for these HSOP Shares was €2.00 per share, plus a reallocation compensation amount of €2.63 per HSOP Share, so that the sum of the strike price and re-allocation compensation amount reflected the fair market value of one common share at the time of allocation of the HSOP Shares. The HSOP Shares represent the right of the beneficiary to indirectly participate in the appreciation in value of the company through ATAI Life Sciences HSOP GbR, a partnership vehicle established for this purpose (the “Partnership”), upon an exit transaction or other liquidity event under the terms of the partnership agreement. In connection with our corporate reorganization that occurred prior to our initial public offering, the HSOP Shares were converted into common shares. Upon the occurrence of an exit transaction or liquidity event, the holders of HSOP Shares will be obligated to pay to the Partnership an amount per HSOP Share (as converted) equal to the strike price of the HSOP Shares (as increased by the re-allocation compensation amount). Refer to the “Outstanding Equity Awards at Fiscal Year End” table below for information regarding the HSOP Shares held by Mr. Brand.

ATAI Life Sciences US, Inc. maintains a 401(k) retirement savings plan for its employees employed in the United States who satisfy certain eligibility requirements. Our named executive officers in the United States are eligible to participate in the 401(k) plan on the same terms as other full-time employees. Currently, we match 100% of employee contributions to the 401(k) plan, up to 3% of eligible compensation, and these matching contributions are fully vested as of the date on which the contribution is made. We believe that providing a vehicle for tax-deferred retirement savings to our employees in the United States adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies. We did not maintain any private pension or retirement plans for our employees employed in Germany during 2021.

All of our full-time employees in the United States, including our named executive officers, are eligible to participate in our health and welfare plans, including, medical, dental and vision benefits, short-term and long-term disability insurance, and life insurance. Prior to our initial public offering, we reimbursed (or directly paid) 80% of the premium payments for our executive officers, including our named executive officers, for coverage under these plans, which was greater than the amounts paid for our other full-time employees. Following our initial public offering, we reimburse or directly pay 100% of the premium payments for coverage under these plans for all of our employees.

Prior to our initial public offering, Mr. Brand was entitled to reimbursement for 50% of any premiums paid by him for health or long-term care insurance; provided that such reimbursement not exceed the amount we would have paid for the employer share of statutory health and long-term care insurance at the applicable highest contribution rate. Beginning in September 2021, Mr. Brand was entitled to reimbursement for contributions paid by him for private health and long-term care insurance, not to exceed $960 per month.

The amounts paid pursuant to these arrangements during 2021 were less than $10,000 in the aggregate for each named executive officer.

In connection with our initial public offering, we, or ATAI Life Sciences US, Inc., entered into an amended and restated employment agreement with each of our named executive officers.

If we terminate Mr. Brand, Dr. Rao or Dr. Gutiérrez-Esteinou without “cause” or he resigns for “good reason” (each as defined below), subject to his timely executing a release of claims and his continued compliance with certain covenants, he is entitled to receive (i) base salary continuation for a period of nine

months (or 12 months for Mr. Brand); (ii) payment for any earned but unpaid annual bonus for the year prior to the year of termination; and (iii) for Dr. Rao and Dr. Gutiérrez-Esteinou only, reimbursement for continued health coverage pursuant to COBRA for up to nine months following termination.

If we terminate Mr. Brand, Dr. Rao or Dr. Gutiérrez-Esteinou without “cause” or he resigns for “good reason”, in either case, on or within 12 months following a change in control, then, in lieu of the severance payments and benefits described above, subject to his timely executing a release of claims and his continued compliance with certain covenants, he is entitled to receive (i) a lump-sum payment equal to one times (or 1.5 times for Mr. Brand) the sum of his annual base salary and his target annual bonus for the year of termination; (ii) payment for any earned but unpaid annual bonus for the year prior to the year of termination; (iii) for Dr. Rao and Dr. Gutiérrez-Esteinou only, reimbursement for continued health coverage pursuant to COBRA for up to 12 months following termination; and (iv) accelerated vesting of all unvested equity or equity-based awards held by the executive that vest solely based on the passage of time, with any such awards that vest based on the attainment of performance-vesting conditions being governed by the terms of the applicable award agreement. In addition, the time period that the executives have to exercise any unvested options will be extended until the first to occur of (i) 12 months (or 18 months for Mr. Brand) following termination and (ii) the expiration of the remaining term of the applicable option.

In the event Mr. Brand is prevented from working due to illness or other similar reasons for which he is not responsible, or upon his death, he (or his widow and dependents in the case of death) would be entitled to continued payment of his base salary for up to six months, less insurance or similar payments received due to such illness or death.

Upon Mr. Brand’s termination or resignation as a managing director for any reason, he shall be entitled to three months’ notice, or pay in lieu of notice; provided that such payments shall be offset against any severance to which he is otherwise entitled under his employment agreement.

For purposes of the employment agreements, “cause” generally means the executive’s (i) commission of, or indictment for, a felony or any misdemeanor involving moral turpitude, deceit or intentional fraud, (ii) gross negligence, willful misconduct or repeated insubordination with respect to the company or any of its affiliates, (iii) use of alcohol or illegal drugs in a manner that impairs the performance of his obligations under the employment agreement, (iv) misconduct that violates any applicable state or federal law prohibiting workplace harassment or that violates any written policy of the company adopted to prevent workplace harassment or discrimination, (v) conduct which the executive knows or reasonably should have known would cause the company to violate state or federal law, or (vi) repeated failure to substantially perform his employment duties or material breach of his material obligations under the employment agreement if such breach is not cured following notice from the board.

For purposes of the employment agreements, “good reason” generally means (i) subject to an opportunity for notice and cure, the company’s material breach of any material obligation under the employment agreement or (ii) for Mr. Brand only, his involuntary removal as a member of the management board.

Mr. Brand and Dr. Gutiérrez-Esteinou have each agreed to refrain from competing with us while employed and following his termination of employment for any reason for a period of 12 months. Each of our named executive officers has agreed to refrain from soliciting our employees or consultants to terminate their relationship with us and from inducing our clients, licensors, licensees or customers to terminate, breach or materially change their relationship with the company, in each case, while employed and following his termination of employment for any reason for a period 24 months (or 12 months for Dr. Rao).

Prior to the corporate reorganization that occurred in connection with our initial public offering, we were managed by the board of directors of ATAI Life Sciences AG and members of the board of ATAI Life Sciences AG were entitled to receive cash compensation for their service on the board in the following amounts: chairman of the board, €30,000; deputy chairman of the board, €22,500; and member of the board (other than chairman or deputy chairman), €15,000. Members of the board of ATAI Life Sciences AG did not receive equity compensation for their service on the board.

In connection with our initial public offering, we adopted a two-tier board structure consisting of a management board and a supervisory board and are no longer managed by the board of ATAI Life Sciences AG following our initial public offering.

Our shareholders have approved a remuneration policy for our supervisory board pursuant to which our supervisory directors may be entitled to cash and equity compensation in such amounts necessary to attract and retain supervisory directors that have the talent and skills to foster long-term value creation and enhance the sustainable development of the company. The compensation payable under the policy is intended to be competitive in relation to both the market in which the company operates and the nature, complexity and size of the company’s business.

Our supervisory directors currently receive the following amounts for their services on our supervisory board:

Director fees are payable in arrears in four equal quarterly installments not later than the thirtieth day following the final day of each calendar quarter, provided that the amount of each payment is prorated for any portion of a quarter that a director is not serving on our supervisory board.

Options granted to our non-employee directors have an exercise price equal to the fair market value of a common share on the date of grant and expire not later than ten years after the date of grant. Options granted upon a director’s initial election or appointment vest as to one-third of the shares on the first anniversary of the date of grant and in twenty-four (24) substantially equal monthly installments thereafter until the third anniversary of the date of grant. Options granted annually to directors vest in a single installment on the earlier of the day before the next annual meeting or the first anniversary of the date of grant. In addition, all unvested options vest in full upon the occurrence of a change in control.

The following table sets forth information concerning the compensation of non-employee members of our board for service on the board for the year ended December 31, 2021. This includes members of the board of ATAI Life Sciences AG prior to our corporate reorganization and members of our supervisory board following our corporate reorganization.

The table below shows the aggregate numbers of option awards (exercisable and unexercisable) held as of December 31, 2021 by each non-employee director. None of the non-employee directors held any unvested stock awards in us as of December 31, 2021.

The following table sets forth information as of December 31, 2021 regarding our equity compensation plans, consisting of the 2021 Incentive Award Plan, the 2020 Employee, Director and Consultant Equity Incentive Plan and the Hurdle Share Option Program. Awards under the Hurdle Share Option Program represent indirect equity interests in us held by ATAI Life Sciences HSOP GbR, a German law private partnership. See Note 12 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 for a description of this program. We do not have any non-shareholder approved equity compensation plans.
