Information About This Proxy Statement

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 Annual 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,

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING

Who is entitled to vote prior to the Annual General Meeting?

The Record Date for the Annual General Meeting is April 19, 2024. 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 Annual General Meeting. Each outstanding common share is entitled to one vote on all matters presented at the Annual General Meeting as voting items. At the close of business on April 19, 2024, there were approximately 167,412,657 common shares outstanding.

What is the difference between being a “record holder” and holding shares in “street name”?

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.

Am I entitled to vote if my shares are held in “street name”?

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 Annual General Meeting unless you obtain a legal proxy from your bank or brokerage firm.

How many shares must be present to hold the Annual General Meeting?

A quorum must be present at the Annual General Meeting for any proposal to be voted on. At the Annual 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 11.

Where and when will the Annual General Meeting be held?

The Annual General Meeting will be held at 6:00 p.m. (Central European Summer Time) on Friday, May 17, 2024. Shareholders may attend the meeting either virtually, by visiting www.virtualshareholdermeeting.com/ATAI2024 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.

Who can attend the Annual General Meeting?

You may attend the Annual General Meeting if you are a Person with Meeting Rights (see above under “Who is entitled to vote prior to the Annual General Meeting?”), or if you hold a valid proxy from a Person with Meeting Rights for the Annual General Meeting. If you would like to attend the Annual 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 Annual General Meeting. This notice must be received by us no later than 5:00 p.m. (Central European Summer Time) on May 15, 2024. If you do not comply with this requirement, you may be refused attendance of the Annual General Meeting.

Proxyholders who wish to attend the Annual 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 Annual 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.

TABLE OF CONTENTS

You may virtually attend and participate in the Annual General Meeting by visiting www.virtualshareholdermeeting.com/ATAI2024. 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 Annual 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 Annual General Meeting as a “Guest” but you will not be able to ask questions.

What if during the check-in time or during the Annual General Meeting I have technical difficulties or trouble accessing the virtual meeting website?

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 Annual General Meeting login page.

Will atai’s supervisory directors attend the Annual General Meeting?

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

What if a quorum is not present at the Annual General Meeting?

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

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

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.

How do I vote?

Shareholders of Record - If you are a shareholder of record, you have the right to vote online or in person at the Annual 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:

•	by Telephone - You can vote by telephone by calling 1-800-690-6903 and following the instructions on the proxy card;

•	by Internet – You can vote over the Internet at www.proxyvote.com by following the instructions on the proxy card;

•	by Mail – You can vote by mail by signing, dating and mailing the proxy card; or

•	by Email – You can vote by email by signing, dating and emailing the proxy card to annualmeeting@atai.life.

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 Annual 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.

TABLE OF CONTENTS

If your 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 or broker to obtain a legal proxy, bring it to the Annual General Meeting in order to vote and notify us in writing of your identity and intention to attend the Annual General Meeting (see above under “Who can attend the Annual General Meeting?”).

Can I change my vote after I submit my proxy?

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

•	submitting a duly executed proxy bearing a later date;

•	by granting a subsequent proxy through the Internet or telephone; or

•	revoking your proxy by voting at the Annual General Meeting.

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.

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 Annual General Meeting by obtaining a legal proxy from your bank or broker, bringing your legal proxy to the Annual General Meeting in order to vote and notifying the Company in writing of your identity and intention to attend the Annual General Meeting (see above under “Who can attend the Annual General Meeting?”).

What if I do not specify how my shares are to be voted?

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.

Who will count the votes?

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 Annual 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).

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

No business shall be voted on at the Annual General Meeting, except such items as included in the agenda for the meeting included on pages 1 and 2 of this proxy statement.

How many votes are required for the approval of the proposals to be voted upon?

Other than the proposal to re-appoint Christian Angermayer as supervisory director, the proposals to appoint each of Scott Braunstein, M.D., Laurent Fischer, M.D., and Raymond Sanchez, M.D., as supervisory directors, and the proposal to appoint Anne Johnson as a managing director, each voting item on the agenda for the Annual General Meeting requires the affirmative vote of a simple majority of the valid votes cast. Proposals 4, 5, 6 and 7 to re-appoint Christian Angermayer and to appoint each of Drs. Braunstein, Fischer and Sanchez as a supervisory director, respectively, are each based on a binding nomination proposed by the supervisory board. Proposal 8 to appoint Anne Johnson 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 Annual General Meeting, unless the nomination is overruled by the Annual 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 re-appointment.

TABLE OF CONTENTS

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 our articles of association, shares abstaining from voting will not count as votes cast at the Annual General Meeting for any of the Proposals presented as voting items, but will count as shares present and entitled to vote for purposes of determining a quorum. Abstentions will have no effect on the outcome of the votes of the proposals presented at the Annual General Meeting.

How many votes do I have?

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.

What are broker non-votes and do they count for determining a quorum?

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, which include all proposals other than Proposal 2. We do not expect any broker non-votes in connection with Proposal 2. Broker non-votes are not considered to be votes cast and accordingly will have no effect on the outcome of the votes on the proposals presented at the Annual General Meeting.

How do we solicit proxies?

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.

Where can I find the voting results of the Annual General Meeting?

We plan to announce whether the Proposals have passed at the Annual 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 within four business days of the Annual General Meeting.

PROPOSAL 1

ADOPTION OF DUTCH STATUTORY ANNUAL ACCOUNTS OVER FISCAL YEAR 2023

The Annual General Meeting, as required under Dutch law, will be asked to adopt our Dutch statutory annual accounts over fiscal year 2023, which are comprised of our company annual accounts and consolidated annual accounts. This approval also extends to the approval of the use of the English language for the line items in our Dutch statutory annual accounts and the preparation of our annual reports (for this and other fiscal years).

Our Dutch statutory consolidated annual accounts are prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”) and are different from the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2023 that were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and filed with the SEC. The Dutch statutory annual accounts contain some disclosures that are not required under U.S. GAAP and not contained in our Annual Report on Form 10-K. The adoption of the Dutch statutory annual accounts will also mean that the result for the applicable financial year is allocated in the manner stipulated therein.

A copy of our Dutch statutory annual accounts over fiscal year 2023 will be included in our Dutch statutory annual report over fiscal year 2023, which will be made available on our website at www.atai.life and at our offices located at Wallstraße 16, 10179 Berlin, Germany, no later than the earlier of (i) the 15^th day prior to the day of the Annual General Meeting or (ii) the day of convening of the Annual General Meeting.

Vote Required

Provided that the requisite quorum is present or represented at the Annual General Meeting, this proposal requires a simple majority of votes cast in favor of the proposal.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF SUPERVISORY DIRECTORS

The audit committee has reviewed our U.S. GAAP audited financial statements for the fiscal year ended December 31, 2023 and has discussed these financial statements with management and our independent registered public accounting firm. The audit committee has also received from, and discussed with, our independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the audit committee, including the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

Our independent registered public accounting firm also provided the audit committee with a formal written statement required by the applicable requirements of the PCAOB describing all relationships between the independent registered public accounting firm and us, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the audit committee concerning independence. In addition, the audit committee discussed with the independent registered public accounting firm its independence from us. The audit committee also considered whether the independent registered public accounting firm’s provision of certain other non-audit related services to us is compatible with maintaining such firm’s independence.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the audit committee recommended to the board of supervisory directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM. FEES AND OTHER MATTERS

The following table summarizes fees billed to us for the fiscal years ended December 31, 2023 and 2022, by Deloitte & Touche LLP and Deloitte Accountants B.V., our independent registered public accounting firms (in thousands):

Fee Category	2023	2022
Audit Fees	$2,283	$3,326
Audit-Related Fees	—	—
Tax Fees	—	—
All Other Fees	5	3
Total Fees	$3,288	$3,329

Audit Fees

Audit fees consist of fees associated with the audit of our annual consolidated financial statements, statutory audits, reviews of our quarterly consolidated financial statements, issuances of consents and comfort letters, and assistance with review of documents filed with the SEC, and are all services that are normally provided by the accounting firm in connection with our statutory and regulatory filings or engagements.

All Other Fees

All other fees consist of an annual license fee for access to an accounting research software application.

Audit Committee Pre-Approval Policy and Procedures

The audit committee has adopted a policy (the “Pre-Approval Policy”) that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved. The Pre-Approval Policy generally provides that we will not engage Deloitte & Touche LLP and Deloitte Accountants B.V. to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the audit committee (“specific pre-approval”) or (ii) entered into pursuant to the pre-approval policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by Deloitte & Touche LLP and Deloitte Accountants B.V. has received general pre-approval under the Pre-Approval Policy, it requires specific pre-approval by the audit committee or by a designated member of the audit committee to whom the committee has delegated the authority to grant pre-approvals. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval. For both types of pre-approval, the audit committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The audit committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with our business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance our ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. On an annual basis, the audit committee reviews and generally pre-approves the services (and related fee levels or budgeted amounts) that may be provided by Deloitte & Touche LLP and Deloitte Accountants B.V. without first obtaining specific pre-approval from the audit committee. The audit committee may revise the list of general pre-approved services from time to time, based on subsequent determinations.

CORPORATE GOVERNANCE

General

Our supervisory board has adopted, among other policies, Rules of the Board of Supervisory Directors, an Insider Trading Compliance Policy, a Code of Conduct and charters for each of our audit, compensation and nominating committees to assist the supervisory board in the exercise of its responsibilities and to serve as a framework for our effective governance. You can access our committee charters and our Rules of the Board of Supervisory Directors in the Corporate Governance section under Governance Documents of the Investors page of our website located at www.atai.life.

Supervisory Board Composition

Our supervisory board currently consists of six members: Christian Angermayer, Michael Auerbach, Jason Camm, Sabrina Martucci Johnson, Amir Kalali and Andrea Heslin Smiley. Each supervisory board member is appointed for an initial term of up to three years. Our articles of association provide that the number of supervisory directors may only be determined by our supervisory board. Our supervisory directors are appointed on the basis of a binding nomination prepared by our supervisory board. 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.

Supervisory Director Independence

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.

Supervisory Director Candidates

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. Scott Braunstein, M.D., Laurent Fischer, M.D., and Raymond Sanchez, MD., each a nominee for appointment to our supervisory board, were recommended as potential candidates to serve on our supervisory board by LifeSci Search, a leading global executive search firm specializing in the healthcare sector.

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,

TABLE OF CONTENTS

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.”

Communications from Shareholders

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

Supervisory Board Leadership Structure and Role in Risk Oversight

Our supervisory board is comprised of individuals with extensive experience in the life sciences industry. 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 April 2022 the supervisory board appointed Michael Auerbach to serve as lead independent 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

TABLE OF CONTENTS

2013 and Dentons Global Advisors (formerly Albright Stonebridge Group, a global consulting firm founded by former Secretary of State Madeleine Albright) since 2012.

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.

Annual Board Evaluation

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.

Code of Conduct

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 2023.

Anti-Hedging Policy

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.

TABLE OF CONTENTS

Clawback Policy

We have adopted a Recovery of Erroneously Awarded Compensation Policy, effective as of October 2, 2023, as required by Rule 10D-1 under the Securities Exchange Act of 1934, as amended, and the corresponding listing standards of the Nasdaq Stock Exchange. This policy provides for the mandatory recovery (subject to limited exceptions) from current and former officers of incentive-based compensation that was erroneously received during the three years preceding the date that we are required to prepare an accounting restatement. The amount required to be recovered is the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the restated financial measure.

Attendance by Members of the Supervisory Board at Meetings

There were four meetings of the supervisory board during fiscal year 2023. During fiscal year 2023, each incumbent director attended at least 75% of the aggregate of (i) all meetings of the supervisory board and (ii) all 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.

TABLE OF CONTENTS

COMMITTEES OF THE SUPERVISORY BOARD

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.lfe. All of the members of each of these committees are independent as defined under the Nasdaq rules. Our supervisory board has affirmatively determined that Sabrina Martucci Johnson, Amir Kalali and Andrea Heslin Smiley meet the independence requirements of Rule 10A-3 under the Exchange Act and Nasdaq rules 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 committees of the supervisory board. Each of Scott Braunstein, M.D., Laurent Fischer, M.D., and Raymond Sanchez, M.D., have not yet been appointed to serve on a committee of the supervisory board. Our supervisory board shall determine on which, if any, committees of our supervisory board Drs. Braunstein, Fischer, and Sanchez shall serve, if elected.

Audit Committee

Our audit committee’s duties and responsibilities include:

•

the appointment, compensation, retention and oversight of the work of the independent auditor (including resolution of any disagreements between management and the independent auditor regarding financial reporting) and any other registered public accounting firm engaged for the purpose of preparing or issuing an audit report or related work or performing other audit, review or attestation services for us, and the independent auditor and each such other registered public accounting firm must report directly to the committee. The audit committee (or any member to whom pre-approval authority has been delegated) must pre-approve any audit and non-audit service provided to us by the independent auditor, unless the engagement is entered into pursuant to appropriate pre-approval policies established by the committee or if such service falls within available exceptions under SEC rules;

•

to review, discuss with our independent auditor and approve the functions of our internal auditor, including its purpose, authority, organization, responsibilities, budget and staffing; and review the scope and performance of the internal audit plan, including the results of any internal audits, any reports to management and management’s response to those reports;

•

to ensure that the independent auditor prepares and delivers, at least annually, a written statement delineating all relationships between the independent auditor and us, must actively engage in a dialogue with the independent auditor with respect to any disclosed relationships or services that, in the view of the committee, may impact the objectivity and independence of the independent auditor, and, if the committee determines that further inquiry is advisable, must take appropriate action in response to the independent auditor’s report to satisfy itself of the auditor’s independence;

The committee must also consider and discuss and, as appropriate, grant requested waivers from the Code of Conduct brought to the attention of the committee, though the committee may defer any decision with respect to any waiver to the supervisory board.

The members of the audit committee are Ms. Sabrina Martucci Johnson (who serves as chair of the audit committee), Dr. Kalali 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 Ms. Sabrina Martucci Johnson 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 eight times in 2023.

Compensation Committee

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:

•

to review and recommend for approval by the supervisory board the compensation of our chief executive officer and other executive officers, including members of the management board, including salary, bonus and incentive compensation levels; deferred compensation; executive perquisites; equity compensation (including awards to induce employment); severance arrangements; change-in-control benefits; and other forms of executive officer compensation. The committee shall meet without the presence of executive officers when approving or deliberating on chief executive officer compensation but may, in its discretion, invite the chief executive officer to be present during the approval of, or deliberations with respect to, other executive officer compensation;

•	to periodically review and make recommendations to the supervisory board regarding managing director and supervisory director compensation;

•	prepare the annual Compensation Committee Report, to the extent required under applicable rules and regulations of the Securities and Exchange Commission;

•

to the extent that we are required to include a “Compensation Discussion and Analysis” (“CD&A”) in our Annual Report on Form 10-K or annual proxy statement, the committee will review and discuss with management the CD&A and will consider whether it will recommend to the supervisory board that the CD&A be included in the appropriate filing;

•	periodically perform an evaluation of its performance; and

•	annually review and reassess the committee’s charter and submit any recommended changes to the supervisory directors for consideration.

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 2023, the compensation committee engaged Radford, which is part of the Rewards solutions practice at Aon plc (“Radford”). 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 Mr. Auerbach and Ms. Smiley (who serves as chair of the compensation committee). The compensation committee met five times during 2023.

Nominating Committee

Our nominating committee’s responsibilities include:

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table presents information relating to the beneficial ownership of our common shares as of April 9, 2024 by:

•	each person, or group of affiliated persons, known by us to own beneficially 5% or more of our common shares;

•	each managing director, named executive officer, supervisory director and supervisory director nominee, individually; and

•	all managing directors, executive officers and supervisory directors as a group.

The number of common shares beneficially owned by each shareholder is determined in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, beneficial ownership includes any common shares over which the individual or entity has sole or shared voting power or investment power. Applicable percentage ownership is based on 167,393,143 common shares outstanding as of April 9, 2024. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, common shares subject to options, restricted share units or other rights held by such person that are currently exercisable or will become exercisable or will vest within 60 days of April 9, 2024 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Except as otherwise indicated, and subject to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all common shares held by that person.

Unless otherwise indicated below, the address for each beneficial owner is atai Life Sciences N.V., Wallstraße 16, 10179 Berlin, Germany.

Related Party Transaction Policy

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:

•	whether the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party; and

•	the extent of the related person’s interest in the transaction and the conflicts of interest and corporate opportunity provisions of the Company’s Code of Conduct.

Narrative to 2023 Summary Compensation Table

General

Our executive compensation program is designed to align executive pay with our performance on both short-term and long-term bases, link executive pay to stockholder value creation, and utilize compensation as a tool to assist us in attracting and retaining the high-caliber executives that we believe are critical to our long-term success. Our equity-based awards are subject to vesting over a number of years and, in some instances, the achievement of pre-established performance metrics. Additionally, these awards only provide value to the extent our stock price increases over time. Therefore, “total” compensation as shown in the table above and calculated in accordance with SEC and applicable accounting rules, is not necessarily reflective of the compensation actually realized by our named executive officers for a given year.

TABLE OF CONTENTS

Please see the remaining sections of this “Narrative to 2023 Summary Compensation Table” for a description of all of the elements that comprise our executive compensation program for 2023.

2023 Salaries

The named executive officers receive a base salary to compensate them for services rendered to our 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. During 2023, our management board approved the annual base salaries of our named executive officers as set forth in the following table. There were no changes in the base salaries of Mr. Brand, Dr. Rao, Mr. Bardin or Dr. Gutierrez-Enteinou from the prior year. Ms. Johnson’s base salary was entered into in connection with her promotion to Chief Accounting Officer during 2023.

Name			2023 Annual Base Salary
Florian Brand			$550,000
Srinivas Rao, M.D., Ph.D.			$550,000
Anne Johnson			$360,000
Stephen Bardin			$440,000
Rolando Gutierrez-Esteinou, M.D.			$440,000

2023 Cash-Based Incentive Compensation

We provide annual bonuses designed to motivate and reward our executives, including our named executive officers, for achievements relative to certain Company performance metrics for the year. Each named executive officer’s target bonus opportunity is expressed as a percentage of annual base salary. The 2023 annual bonuses for Mr. Brand, Dr. Rao, Ms. Johnson, Mr. Bardin, and Dr. Gutierrez-Esteinou were targeted at 50%, 50%, 40%, 40%, and 40% of their respective base salaries.

In March 2024, in consultation with our management board and upon the recommendation of the compensation committee, the supervisory board determined that the 2023 corporate, clinical and financing goals were achieved at 85%. As such, 2023 bonuses for our named executive officers were generally paid at 85% of their target bonus opportunities. Prior to being appointed to Chief Accounting Officer in May 2023, Ms. Johnson’s annual bonus was earned based on the achievement against company performance goals (75%) and individual performance goals (25%). In accordance with Dr. Gutierrez-Esteinou’s separation agreement as described below, he was eligible to receive a pro-rated portion of his 2023 annual bonus based on actual performance for calendar year 2023.

The bonuses awarded to our named executive officers for 2023 performance are set forth above in the 2023 Summary Compensation Table in the column entitled “Bonus”.

Equity Compensation

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 or her 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. During 2023, the Company also granted restricted stock units (or RSUs) to executive officers. The RSUs vest 50% on the first anniversary of the vesting commencement date and the remaining 50% vest on the second anniversary of the vesting commencement date.

TABLE OF CONTENTS

The following table sets forth the aggregate number of options and RSUs granted to our named executive officers during 2023.

Named Executive Officer	2023 Options Granted	2023 RSUs Granted
Florian Brand	1,600,000	700,000
Srinivas Rao, M.D., Ph.D.	600,000	350,000
Anne Johnson	500,000	200,000
Stephen Bardin	600,000	350,000
Rolando Gutierrez-Esteinou, M.D.	500,000	200,000

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

Other Elements of Compensation

Retirement Plans

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 or the United Kingdom during 2023.

Employee Benefits and Perquisites

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. During 2023, we reimbursed or directly paid 100% of the premium payments for coverage under these plans for all of our employees.

During 2023, 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, which amounts are reported in the “All Other Compensation” column of the 2023 Summary Compensation Table above.

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.
