CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS

This Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2022 (the “Quarterly Report) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements contained in this Quarterly Report other than statements of historical fact, including statements regarding our future operating results and financial position, the success, cost and timing of development of our product candidates, including the progress of preclinical and clinical trials and related milestones, the commercialization of our current product candidates and any other product candidates we may identify and pursue, if approved, including our ability to successfully build a specialty sales force and commercial infrastructure to market our current product candidates and any other product candidates we may identify and pursue, the timing of and our ability to obtain and maintain regulatory approvals, macroeconomic, geopolitical, health and industry trends, our business strategy and plans, potential acquisitions, and the plans and objectives of management for future operations and capital expenditures, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan,” “potentially,” “preliminary,” “likely,” and similar expressions are intended to identify forward-looking statements.

We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of important factors that could cause actual results to differ materially from those expressed or implied by the forward-looking statements, including without limitation: we are a clinical-stage biopharmaceutical company and have incurred significant losses since our inception, and we anticipate that we will continue to incur significant losses for the foreseeable future; we will require substantial additional funding to achieve our business goals, and if we are unable to obtain this funding when needed and on acceptable terms, we could be forced to delay, limit or terminate our product development efforts; our limited operating history may make it difficult to evaluate the success of our business and to assess our future viability; we have never generated revenue and may never be profitable; our product candidates contain controlled substances, the use of which may generate public controversy; clinical and preclinical development is uncertain, and our preclinical programs may experience delays or may never advance to clinical trials; we rely on third parties to assist in conducting our clinical trials and some aspects of our research and preclinical testing, and those clinical trials, including progress and related milestones, may be impacted by several factors including the failure by such third parties to meet deadlines for the completion of such trials, research, or testing, changes to trial sites and other circumstances; we currently rely on qualified therapists working at third-party clinical trial sites to administer certain of our product candidates in our clinical trials and we expect this to continue upon approval, if any, of our current or future product candidate, and if third-party sites fail to recruit and retain a sufficient number of therapists or effectively manage their therapists, our business, financial condition and results of operations would be materially harmed; we cannot give any assurance that any of our product candidates will receive regulatory approval, which is necessary before they can be commercialized; research and development of drugs targeting the central nervous system, or CNS, is particularly difficult, and it can be difficult to predict and understand why a drug has a positive effect on some patients but not others; we face significant competition in an environment of rapid technological and scientific change; third parties may claim that we are infringing, misappropriating or otherwise violating their intellectual property rights, the outcome of which would be uncertain and may prevent or delay our development and commercialization efforts; a change in our effective place of management may increase our aggregate tax burden; we identified material weaknesses in connection with our internal control over financial reporting; and a pandemic, epidemic, or outbreak of an infectious disease, such as the COVID-19 pandemic, may materially and adversely affect our business, including our preclinical studies, clinical trials, third parties on whom we rely, our supply chain, our ability to raise capital, our ability to conduct regular business and our financial results. Other important factors include the risks, uncertainties, and assumptions described under “Risk Factors" in our Form 10-K for the year ended December 31, 2021 (the "Form 10-K") and this Quarterly Report, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 2 of this Quarterly Report, and elsewhere in our filings with the Securities and Exchange Commission (“SEC”).

Any forward-looking statements made herein speak only as of the date of this Quarterly Report, and you should not rely on forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, performance, or achievements reflected in the forward-looking statements will be achieved or will occur. Except as required by applicable law, we undertake no obligation to update any of these forward-looking statements for any reason after the date of this Quarterly Report or to conform these statements to actual results or revised expectations.

1. Organization and Description of Business

ATAI Life Sciences N.V. (“atai”) is the parent company of ATAI Life Sciences AG and, along with its subsidiaries, is a clinical-stage biopharmaceutical company aiming to transform the treatment of mental health disorders. atai was founded in 2018 as a response to the significant unmet need and lack of innovation in the mental health treatment landscape. atai is dedicated to acquiring, incubating and efficiently developing innovative therapeutics to treat depression, anxiety, addiction, and other mental health disorders.

Since inception, atai has either created wholly owned subsidiaries or has made investments in certain controlled entities, including variable interest entities (“VIEs”) for which atai is the primary beneficiary under the VIE model (collectively, the “Company”). atai is headquartered in Berlin, Germany.

The Company has determined that it has one operating and reporting segment.

Corporate Reorganization and Initial Public Offering

atai was incorporated pursuant to the laws of the Netherlands as a Dutch private company with limited liability on September 10, 2020 for the purposes of becoming a holding company for ATAI Life Sciences AG and consummating the corporate reorganization described below. atai did not conduct any operations prior to the corporate reorganization other than activities incidental to its formation. ATAI Life Sciences AG was formed as a separate company on February 7, 2018.

In contemplation of the consummation of atai’s initial public offering (“IPO”) of common shares, atai undertook a corporate reorganization (the “Corporate Reorganization”). The Corporate Reorganization consisted of several steps as described below:

•Exchange of ATAI Life Sciences AG Securities for ATAI Life Sciences B.V. Common Shares and Share Split: In April 2021, the existing shareholders of ATAI Life Sciences AG each became a party to a separate notarial deed of issue under Dutch law and (i) subscribed for new common shares in ATAI Life Sciences B.V. and (ii) transferred their respective shares in ATAI Life Sciences AG, on a 1 to 10 basis (the “Exchange Ratio”), to ATAI Life Sciences B.V. as a contribution in kind on the common shares in ATAI Life Sciences B.V. As a result of the issuance of common shares in ATAI Life Sciences B.V. to the shareholders of ATAI Life Sciences AG and the contribution and transfer of their respective shares in ATAI Life Sciences AG to ATAI Life Sciences B.V., ATAI Life Sciences AG became a wholly owned subsidiary of ATAI Life Sciences B.V. No shareholder rights or preferences changed as a result of the share for share exchange. In connection with such exchange, the common share in ATAI Life Sciences B.V. held by Apeiron was cancelled. On June 7, 2021, shares of ATAI Life Sciences B.V. were split applying a ratio of 1.6 to one, and the nominal value of the shares was reduced to €0.10, pursuant to a shareholders’ resolution and amendment to the articles of association.

•Conversion of ATAI Life Sciences B.V. into ATAI Life Sciences N.V.: Immediately preceding the Company’s IPO, the legal form of ATAI Life Sciences B.V. was converted from a Dutch private company with limited liability to a Dutch public company, and the articles of association of ATAI Life Sciences N.V., became effective. Following the Corporate Reorganization, ATAI Life Sciences N.V. became the holding company of ATAI Life Sciences AG.

The Corporate Reorganization, as described above, is considered a continuation of ATAI Life Sciences AG resulting in no change in the carrying values of assets or liabilities. As a result, the financial statements for periods prior to the Corporate Reorganization are the financial statements of ATAI Life Sciences AG as the predecessor to atai for accounting and reporting purposes. All share, per-share and related information presented in these condensed consolidated financial statements and corresponding disclosure notes have been retrospectively adjusted, where applicable, to reflect the impact of the share exchange and share split resulting from the Corporate Reorganization. In connection with the Corporate Reorganization, outstanding share awards and option grants of ATAI Life Sciences AG were exchanged for share awards and option grants of ATAI Life Sciences B.V. with identical restrictions.

On June 22, 2021, atai closed the IPO of its common shares on the Nasdaq Stock Market ("Nasdaq"). As part of the IPO, the Company issued and sold 17,250,000 shares of its common shares, which included 2,250,000 shares sold pursuant to the exercise of the underwriters’ over-allotment option, at a public offering price of $15.00 per share. The Company received net proceeds of approximately $231.6 million from the IPO, after deducting underwriters’ discounts and commissions of $18.1 million and offering costs of $9.0 million.

Impact of COVID-19 Pandemic

The COVID-19 pandemic has continued to present global public health and economic challenges during the six months ended June 30, 2022. Although some research and development timelines have been impacted by delays related to the COVID-19 pandemic, the Company has not experienced material financial impacts on its business and operations as a result. The Company continues to monitor the impact of the COVID-19 pandemic on its employees and business and has undertaken business continuity measures to mitigate potential disruption to its operations.

9

The future impact of COVID-19 on the Company’s business and operations, including its research and development programs and related clinical trials, will largely depend on future developments, which are highly uncertain, such as the duration of the pandemic, the spread of the disease and variants thereof, the availability and effectiveness of vaccines and related roll-out efforts, breakthrough infections among the vaccinated, vaccine hesitancy, the implementation of vaccine mandates, travel restrictions, social distancing and related government actions around the world, business closures or business disruptions and the ultimate impact of COVID-19 on financial markets and the global economy.

Liquidity and Going Concern

The Company has incurred significant losses and negative cash flows from operations since its inception. As of June 30, 2022, the Company had cash and cash equivalents of $84.1 million, short-term securities of $228.4 million and its accumulated deficit was $431.3 million. The Company has historically financed its operations through the sale of equity securities, sale of convertible notes and revenue generated from licensing and collaboration arrangements. The Company has not generated any revenues to date from the sale of its product candidates and does not anticipate generating any revenues from the sale of its product candidates unless and until it successfully completes development and obtains regulatory approval to market its product candidates.

The Company currently expects that its existing cash and cash equivalents and short-term securities as of June 30, 2022 will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months from the date the condensed consolidated financial statements are issued.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and follow the requirements of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and disclosures required by U.S. GAAP for complete financial statements as certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted.

The Company's condensed consolidated financial statements include the accounts of the Company and the accounts of the Company's subsidiaries. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). All intercompany transactions and accounts have been eliminated in consolidation.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the Company’s financial position, its results of operations and comprehensive loss, and its cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other future annual or interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC on March 30, 2022.

Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the condensed consolidated statements of operations for the three and six month periods ended June 30, 2021 to reclassify the foreign exchange loss. The foreign exchange loss for the three and six month periods ended June 30, 2021 was previously included in the other expense, net financial statement line.

Significant Accounting Policies

During the six months ended June 30, 2022, there were no significant changes to the Company’s significant accounting policies as described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2021 except as described below.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to the fair value of the Company’s investment in Intelgenx Technologies Corp. (“IntelGenx”), securities carried at fair value, contingent consideration liability—related parties, in-process research and development assets (“IPRD”), redeemable noncontrolling interests and noncontrolling interests

10

recognized in acquisitions, the valuations of common shares prior to IPO and share-based awards, and accruals for research and development costs.

The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. Actual results may differ from those estimates or assumptions.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. As of June 30, 2022 and December 31, 2021, cash and cash equivalents consisted of cash on deposit and cash held in high-yield savings accounts and money market funds.

Investment Securities Portfolio

The following table sets forth the fair value of atai's available-for-sale securities portfolio at the dates indicated:

	Fair Value
	June 30, 2022		December 31, 2021
Money Market Funds	$	38,878	$	—
U.S. Treasuries		3,478		—
Commercial Paper		114,880		—
Corporate Notes/Bonds		107,045		—
U.S. Government Agencies		2,951		—
	$	267,232	$	—

In January 2022, the Company invested in a certain investment portfolio, which is comprised of Money Market Funds, U.S. Treasury securities, Commercial Paper, Corporate Notes/Bonds, and U.S. government agencies securities. The Company classified securities in the investment portfolio as available-for-sale securities. Furthermore, the Company elected the fair value option for the available-for-sale securities in the investment portfolio (see Note 7). The decision to elect the fair value option, which is irrevocable once elected, is determined on an instrument-by-instrument basis and applied to an entire instrument. The net gains or losses, if any, on an investment for which the fair value option has been elected are recognized as a change in fair value of securities on the Consolidated Statements of Operations and the amortized cost of investments approximates their fair value.

Fair Value Measurements

Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s contingent consideration liability—related parties, derivative liability associated with the Perception convertible promissory notes, IntelGenx Initial Warrants and IntelGenx Additional Units Warrant, and warrant liability with Neuronasal Inc. are carried at fair value, determined according to Level 3 inputs in the fair value hierarchy described above (See Note 7). The IntelGenx common stock and securities carried at fair value are determined according to Level 2 inputs in the fair value hierarchy above. The carrying amount reflected in the accompanying consolidated balance sheets for cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values, due to their short-term nature.

11

The carrying amounts of the Company’s remaining outstanding convertible promissory notes—related parties issued in 2018 and 2020 (collectively, the “2018 Convertible Notes”) do not approximate fair value because the fair value is driven by the underlying value of the Company’s common shares into which the notes are to be converted. As of June 30, 2022, the carrying amount and fair value amount of the 2018 Convertible Notes was $0.6 million and $28.8 million, respectively. As of December 31, 2021, the carrying amount and fair value amount of the 2018 Convertible Notes was $0.8 million and $69.7 million, respectively. Subsequent to the IPO, several noteholders of the 2018 Convertible Notes elected to convert their promissory notes into the Company's common shares. See Note 10 for additional discussion.

Fair Value Option

As permitted under Accounting Standards Codification 825, Financial Instruments, or ASC 825, the Company has elected the fair value option to account for its investment in common shares of IntelGenx, which otherwise would be subject to ASC 323. In accordance with ASC 825, the Company records this investment at fair value under Other investments held at fair value in the Company's consolidated balance sheets and changes in fair value are recognized as a component of other income (expense), net in the consolidated statements of operations. The carrying value of the investment remained at zero as of June 30, 2022 and December 31, 2021, respectively.

Furthermore, as noted above the Company also elected the fair value option for its investment securities portfolio.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

As described in “Recently Adopted Accounting Pronouncements” below, the Company early adopted certain accounting standards, as the JOBS Act does not preclude an emerging growth company from adopting a new or revised accounting standard earlier than the time that such standard applies to private companies. The Company expects to use the extended transition period for any other new or revised accounting standards during the period in which it remains an emerging growth company.

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is a comprehensive new lease standard that amends various aspects of existing accounting guidance for leases. The core principle of Topic 842 requires lessees to recognize on the consolidated balance sheets a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases with lease terms greater than twelve months. The lease liability is measured at the present value of the unpaid lease payments and the right-of-use asset is derived from the calculation of the lease liability. Topic 842 also requires lessees to disclose key information about leasing arrangements. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. As a result of the Company having elected the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act, ASU 2016-02 is effective for the Company beginning after December 15, 2021.

The Company adopted the new standard on January 1, 2022 using the modified transition approach as of the effective date.

The new standard provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permitted it to not reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs. As a result, the Company has continued to account for existing leases - i.e. leases for which the commencement date is before January 1, 2022 - in accordance with Topic 840 throughout the entire lease term, including periods after the effective date, with the exception that the Company applied the new balance sheet recognition guidance for operating leases and applied Topic 842 for remeasurements and modifications after the Transition Date. The Company also elected the hindsight expedient in determining the lease term and assessing impairment of right-of-use assets when transitioning to ASC 842. As a result, the Company evaluated the lease term for its existing leases as of the transition date, January 1, 2022.

The most significant impact of the adoption of Topic 842 on the Company’s condensed consolidated financial statements was the recognition of a $0.2 million operating lease right-of-use asset, a $0.1 million current operating lease liability, and a $0.1 million long-term operating lease liability on the Company’s condensed consolidated balance sheet related to its existing facility operating lease. The Company did not have a deferred rent liability recorded in connection with its existing facility operating lease. There was no material impact to the Company’s condensed consolidated balance sheet, statement of operations, and no cumulative-effect adjustment to

12

accumulated deficit. The Company recorded an immaterial amount of general and administrative expense in its consolidated statement of operations related to lease expense, including short-term lease expense during the three and six months ended June 30, 2022.

Recently Issued Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses. This update requires immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred. The new model is applicable to most financial assets and certain other instruments that are not measured at fair value through net income. In November 2019, the FASB issued ASU 2019-10, which delays adoption for "smaller reporting companies" as defined under the rules promulgated under the Exchange Act. Although, as of December 31, 2021, the Company was no longer a smaller reporting company, the Company qualified as a smaller reporting company at the time of its initial public offering and, as such, in accordance with ASU 2019-10, the effective date for adoption by the Company will begin after December 31, 2022. The Company does not expect that the adoption of this new standard will have a material impact on its condensed consolidated financial statements and related disclosures.

3. Acquisitions

2021 Acquisitions

PsyProtix, Inc.

In February 2021, the Company jointly formed PsyProtix with Chymia, LLC (“Chymia”). PsyProtix was created for the purpose of exploring and developing a metabolomics-based precision psychiatry approach, initially targeting the stratification and treatment of Treatment Resistant Depression (“TRD”) patients. In February 2021, pursuant to a Series A Preferred Stock Purchase Agreement (the “PsyProtix Purchase Agreement”), the Company acquired shares of PsyProtix’s Series A preferred stock in exchange for an initial payment of $0.1 million in cash. In addition, pursuant to the PsyProtix Purchase Agreement, the Company agreed to make aggregate payments to PsyProtix of up to $4.9 million upon the achievement of specified clinical milestones to complete the purchase of the shares and provide additional funding to PsyProtix. The PsyProtix Purchase Agreement resulted in the Company holding a 75.0% voting interest and Chymia holding a 25.0% voting interest in PsyProtix. In connection with the Company’s agreement for additional funding, PsyProtix issued the corresponding Series A preferred shares to the Company provided that the shares are held in an escrow account (the “PsyProtix Escrow Shares”). The PsyProtix Escrow Shares will be released, from time to time, to the Company upon PsyProtix achieving certain milestones as defined in the PsyProtix Purchase Agreement with cash payments to be made by the Company. In addition, the Company has the right, but not the obligation, to make payment for the certain PsyProtix Escrow Shares at any time, regardless of the achievement of any milestones. The PsyProtix Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, PsyProtix shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to PsyProtix and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares. In addition, prior to the occurrence of the earlier of a certain milestone event or reaching of the Company’s capital contribution threshold of $5.0 million, PsyProtix will issue additional shares of common stock to Chymia to maintain Chymia’s current ownership percentage. This anti-dilution right was concluded to be embedded in the common shares held by Chymia.

Immediately following the closing of the PsyProtix Purchase Agreement, PsyProtix loaned $0.1 million to Chymia in exchange for a duly executed promissory note (the “Chymia Note”). The Chymia Note shall accrue interest at a 5% rate per annum until payment in full. The aggregate principal amount of $0.1 million, together with all accrued and unpaid interest and all other amounts payable are due to be paid on the date that is the earlier of (i) five years from the promissory note agreement date or (ii) the occurrence of a liquidation event or a deemed liquidation event (as defined in the PsyProtix’s certificate of incorporation). As of June 30, 2022, the Chymia Note was $0.1 million and included as a component of long-term notes receivable—related parties on the consolidated balance sheets.

The PsyProtix Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of PsyProtix. The Company concluded that PsyProtix was not considered a business based on its assessment under ASC 805 and accounted for the Company’s acquisition in PsyProtix as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company did not recognize a gain or a loss in connection with the consolidation of PsyProtix as the fair value of the consideration paid of $0.1 million was equivalent to the fair value of the identifiable assets acquired of $0.1 million.

In October 2021, pursuant to the Board consent letter and the PsyProtix Purchase Agreement discussed above, the Company released a payment in the amount of $0.5 million upon the achievement of specified clinical milestones. Accordingly, 500,000 shares of Series A Preferred Stock were released from the escrow account to the Company. The Company's equity ownership interest in PsyProtix remained unchanged as the PsyProtix Escrow Shares were already deemed issued, outstanding and legally owned by atai.

Psyber, Inc.

Psyber is a globally based startup focused on the development of brain-computer interface-enabled digital therapeutics for treating mental health issues. Psyber was created as a joint venture between the Company and the founders of Psyber. In February 2021, pursuant to a Series A Preferred Stock Purchase Agreement (the “Psyber Purchase Agreement”), the Company acquired shares of Psyber’s Series A Preferred Stock in exchange for an initial payment of $0.2 million in cash. In addition, pursuant to the Psyber Purchase Agreement, the Company agreed to make aggregate payments to Psyber of up to $1.8 million upon the achievement of specified clinical milestones to complete the purchase of the shares and provide additional funding to Psyber. The Psyber Purchase Agreement resulted in the Company holding a 75.0% voting interest and the founders of Psyber jointly holding a 25.0% voting interest in Psyber. In connection with the Company’s agreement for additional funding, Psyber issued the corresponding Series A preferred shares to the Company provided that the shares are held in an escrow account (the “Psyber Escrow Shares”). The Psyber Escrow Shares will be released, from time to time, to the Company upon Psyber achieving certain milestones as defined in the Psyber Purchase Agreement with cash payments to be made by the Company. In addition, the Company has the right, but not the obligation, to make payment for the certain Psyber Escrow Shares at any time, regardless of the achievement of any milestones. The Psyber Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, Psyber shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to Psyber and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares. In addition, prior to the occurrence of the earlier of a certain milestone event or reaching of the Company’s capital contribution threshold of $2.0 million, Psyber will issue additional shares of common stock to the founders of Psyber to maintain the founders’ current ownership percentage. This anti-dilution right was concluded to be embedded in the common shares held by the founders of Psyber.

The Psyber Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of Psyber. The Company concluded that Psyber was not considered a business based on its assessment under ASC 805 and accounted for the Company’s acquisition in Psyber as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company recognized a de minimis gain for the three months ended March 31, 2021. The gain was calculated as the sum of the consideration paid of $0.2 million, less the fair value of identifiable net assets acquired of $0.2 million.

InnarisBio, Inc.

In February 2021, the Company jointly formed InnarisBio with UniQuest Pty Ltd (“UniQuest”) for the purpose of adding a solgel-based direct-to-brain intranasal drug delivery technology to the Company’s platform. In March 2021, pursuant to a Series A Preferred Stock Purchase Agreement (the “InnarisBio Purchase Agreement”), the Company acquired shares of InnarisBio’s Series A preferred stock in exchange for an initial payment of $1.1 million in cash. In addition, pursuant to the InnarisBio Purchase Agreement, the Company agreed to make aggregate payments to InnarisBio of up to $3.9 million upon the achievement of specified clinical milestones to complete the purchase of the shares and provide additional funding to InnarisBio. The InnarisBio Purchase Agreement resulted in the Company holding an 82.0% voting interest and UniQuest holding a 18.0% voting interest in InnarisBio. In connection with the Company’s agreement for additional funding, InnarisBio issued the corresponding shares of Series A preferred stock to the Company provided that the shares are held in an escrow account (the “InnarisBio Escrow Shares”). The InnarisBio Escrow Shares will be released, from time to time, to the Company upon InnarisBio achieving certain milestones as defined in the InnarisBio Purchase Agreement with cash payments to be made by the Company. In addition, the Company has the right, but not the obligation, to make payment for the InnarisBio Escrow Shares at any time, regardless of the achievement of any milestones. The InnarisBio Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, InnarisBio shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to InnarisBio and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares.

The InnarisBio Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of InnarisBio. The Company concluded that InnarisBio was not considered a business based on its assessment under ASC 805 and accounted for the Company’s acquisition in InnarisBio as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company recognized a de minimis loss on consolidation for the three months ended March 31, 2021. The loss was calculated as the sum of the consideration paid of $1.1 million, the fair value of the noncontrolling interest issued of $0.9 million, less the fair value of identifiable net assets acquired of $2.0 million. The fair value of the contingent milestone payments of $0.1 million was included in the total purchase consideration for the noncontrolling interest and recognized as a liability by InnarisBio at the date of acquisition. The fair value of the IPR&D acquired of $1.0 million was reflected as acquired in-process research and development expense on the consolidated statements of operations for the three months ended March 31, 2021 as it had no alternative future use at the time of the acquisition.

14

In November 2021, pursuant to the InnarisBio Purchase Agreement discussed above, the Company released a payment in the amount of $1.2 million upon the achievement of specified clinical milestones. Accordingly, 1,238,000 shares of Series A Preferred Stock were released from the escrow account to the Company. The Company's equity ownership interest in InnarisBio remained unchanged as the InnarisBio Escrow Shares were already deemed issued, outstanding and legally owned by the Company.

Neuronasal, Inc.

Neuronasal, Inc. (“Neuronasal”) is developing a novel intranasal formulation of N-acetylcysteine for acute mild traumatic brain injury. The Company first acquired investments in Neuronasal in December 2019 pursuant to a Preferred Stock Purchase Agreement (the “Neuronasal PSPA”). In December 2019, in connection with the original purchase of the preferred shares, Neuronasal and the Company entered into the Secondary Sale and Put Right Agreement (the “Neuronasal Secondary Sale Agreement”), whereby upon the achievement of certain contingent development milestones, existing common shareholders have the right to sell and the Company has the option but not the obligation to purchase additional shares of common stock at a price determined based on the fair market value per share on the date of exercise. These options that will allow the Company to purchase additional common shares are contingent upon the exercise of the options by Neuronasal’s common shareholders to sell shares to the Company. On March 10, 2021, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares for approximately $0.8 million based on the achievement of certain development milestones. Also, pursuant to the Neuronasal Secondary Sale Agreement, the Company purchased additional common shares for approximately $0.3 million. On May 17, 2021, pursuant to the Neuronasal PSPA the Company exercised its option to purchase additional shares of Series A preferred stock of Neuronasal for an aggregate cost of $1.0 million. The additional purchase on May 17, 2021 resulted in the Company obtaining an aggregate 56.5% ownership interest in Neuronasal, including the Company’s previously acquired investments in Neuronasal’s common and preferred stock, and provided the Company with control of Neuronasal’s board of directors and the unilateral rights to control all decisions related to the significant activities of Neuronasal. Prior to May 17, 2021, the Company accounted for its investments in Neuronasal’s common stock under the equity method and Neuronasal’s preferred stock under the measurement alternative (See Note 5). Following the closing of this acquisition on May 17, 2021, the results of Neuronasal have been consolidated in the Company’s consolidated financial statements.

TryptageniX, Inc.

TryptageniX, Inc. ("TryptageniX"), a Delaware corporation, was incorporated by CB Therapeutics, Inc. (“CBT”) on November 17, 2021, for the purpose of developing and commercializing Intellectual Property (“IP”) and to develop innovative biosynthetic methods to manufacture bioidentical, clinically relevant compounds, including psychoactive compounds which are highly difficult to produce sustainably through traditional methods. TryptageniX will generate New Chemical Entities (“NCE"). In December 2021, pursuant to the Stock Purchase Agreement ("TryptageniX-ATAI Stock Purchase Agreement"), atai acquired Class A Common Stock in exchange for $2.0 million and received a certificate representing additional Class A Common Stock to be held in escrow ("Escrow Shares") by TryptageniX to be released upon achievement of specified clinical milestones and corresponding milestone payments. The TryptageniX-ATAI Stock Purchase Agreement resulted in the Company holding a 65% equity ownership interest and CBT holding a 35% equity ownership interest in TryptageniX. The Escrow Shares will be released, from time to time, to the Company upon TryptageniX achieving certain milestones as defined in the TryptageniX Purchase Agreement with cash payments to be made by the Company. Notwithstanding anything to the contrary, atai shall be the owner of the Escrow Shares and has the right, but not the obligation, to make payment for the Escrow Shares at any time, regardless of the achievement of any milestones. The Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, TryptageniX shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to TryptageniX and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares.

On December 3, 2021, the Company made an additional payment of $1.0 million to CBT for the first installment of a $2.0 million exclusivity fee to become a party to the TryptageniX-ATAI Stock Purchase Agreement. The fee represents the exclusive right to the CBT technology and know-how defined in the TryptageniX Stockholders Agreement. The remaining installment of $1.0 million shall be paid no later than the second anniversary of the acquisition date, either in cash or in common shares of atai.

The TryptageniX-ATAI Stock Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of TryptageniX. The Company concluded that the acquired assets and activities of TryptageniX did not constitute a business based on its assessment under ASC 805 and accounted for the acquisition as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company did not recognize a gain or a loss in connection with the consolidation of TryptageniX as the fair value of the consideration paid of $1.0 million was equivalent to the fair value of identifiable net assets acquired of $6.5 million, less the fair value of the noncontrolling interest issued of $3.9 million, fair value of the contingent consideration of $0.9 million, and fair value of liability for seller financing of $0.8 million. In December 2021, the Company elected to expense the entire fair value of the acquired IPR&D asset of $6.5 million as it had no alternative use at the acquisition date.

15

All acquisitions discussed above were considered as asset acquisitions and no goodwill was recognized upon consolidation.

4. Variable Interest Entities

Consolidated VIEs

At each reporting period, the Company reassesses whether it remains the primary beneficiary for Variable Interest Entities (“VIEs”) consolidated under the VIE model.

The entities consolidated by the Company are comprised of wholly and partially owned entities for which the Company is the primary beneficiary under the VIE model as the Company has (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses that could potentially be significant to the VIE, or the right to receive benefits from the VIE that could potentially be significant to the VIE. The results of operations of the consolidated entities are included within the Company’s condensed consolidated financial statements from the date of acquisition to June 30, 2022.

As of June 30, 2022 and December 31, 2021, the Company has accounted for the following consolidated investments as VIEs, excluding the wholly owned subsidiaries:

Consolidated Entities	Relationship as of June 30, 2022	Relationship as of December 31, 2021	Date Control Obtained	Ownership % June 30, 2022	Ownership % December 31, 2021
Perception Neuroscience Holdings, Inc.	Controlled VIE	Controlled VIE	November 2018	58.9%	58.9%
Kures, Inc.	Controlled VIE	Controlled VIE	August 2019	64.5%	54.1%
EntheogeniX Biosciences, Inc.	Controlled VIE	Controlled VIE	November 2019	80.0%	80.0%
DemeRx IB, Inc.	Controlled VIE	Controlled VIE	December 2019	59.5%	59.5%
Recognify Life Sciences, Inc.	Controlled VIE	Controlled VIE	November 2020	51.9%	51.9%
PsyProtix, Inc.	Controlled VIE	Controlled VIE	February 2021	75.0%	75.0%
Psyber, Inc.	Controlled VIE	Controlled VIE	February 2021	75.0%	75.0%
InnarisBio, Inc.	Controlled VIE	Controlled VIE	March 2021	82.0%	82.0%
Neuronasal, Inc.	Controlled VIE	Controlled VIE	May 2021	56.5%	56.5%
TryptageniX Inc.	Controlled VIE	Controlled VIE	December 2021	65.0%	65.0%

As of June 30, 2022 and December 31, 2021, the assets of the consolidated VIEs can only be used to settle the obligations of the respective VIEs. The liabilities of the consolidated VIEs are obligations of the respective VIEs and their creditors have no recourse to the general credit or assets of atai.

EntheogeniX Biosciences, Inc.

In November 2019, the Company entered into a series of agreements with Cyclica Inc. ("Cyclica") to form EntheogeniX Biosciences, Inc. ("EntheogeniX"), a company dedicated to developing the next generation of innovative mental health drugs employing an AI-enabled computational biophysics platform designed to optimize and accelerate drug discovery. Based on the Company's assessment of the transaction at the time of acquisition, the Company concluded that EntheogeniX was not a business and accounted for the Company's investment as an initial consolidation of a VIE that is not a business under ASC 810.

In February 2022, pursuant to the business plan as contemplated in the Stockholders Agreement and Subscription for Shares pursuant to the Contribution and Subscription Agreement, atai purchased additional shares of Class A common stock for an aggregate purchase price of $1.0 million. As a result of anti-dilution protection available to Cyclica, the Company's ownership percentage in EntheogeniX did not

16

change due to the Class A common stock purchase. As of June 30, 2022 and December 31, 2021, the Company owned 80% of the outstanding common stock of EntheogeniX.

The purchase of additional Class A common stock was deemed to be a reconsideration event. The Company determined that EntheogeniX is still considered a VIE subsequent to the additional Class A common stock purchase as EntheogeniX does not have sufficient equity at risk to carry out its principal activities without additional subordinated financial support.

The following table presents the assets and liabilities (excluding intercompany balances that were eliminated in consolidation) for all VIEs as of June 30, 2022 (in thousands):

Redeemable Noncontrolling Interests

In connection with the consolidation of Kures, Inc. (“Kures”) the Company recognized the shares of Kures common stock and Series A-1 preferred stock held by the founders of Kures as redeemable noncontrolling interests as they contain embedded put options that are exercisable by the founders following a successful completion of a future event, which is not solely within the control of the Company.

In connection with the consolidation of DemeRx IB, the Company recognized common stock held by DemeRx as redeemable noncontrolling interests as they are redeemable upon the occurrence of events that are not solely within the control of the Company.

In connection with the consolidation of Neuronasal, the Company recognized the shares of Neuronasal common stock held by the founders of Neuronasal as redeemable noncontrolling interests as they contain embedded put options that are exercisable by the founders following a successful completion of a future event, which is not solely within the control of the Company.

The redeemable noncontrolling interests were initially measured at fair value upon issuance and are redeemable at fair value at the holder’s option upon the successful completion or occurrence of future events. As of June 30, 2022 and December 31, 2021, the Company did not adjust the carrying value of the redeemable noncontrolling interests based on their estimated redemption values since it was not probable

18

that the events that would allow the shares to become redeemable would occur. Subsequent adjustments to increase or decrease the carrying values of the redeemable noncontrolling interests to their estimated redemption values will be made if and when it becomes probable that such events will occur.

As of June 30, 2022 and December 31, 2021, the balance of redeemable noncontrolling interests in temporary equity on the consolidated balance sheets was zero. The amount of net loss attributable to redeemable noncontrolling interests of $0 million and $0 million are included in consolidated net loss on the face of the condensed consolidated statements of operations for the three months ended June 30, 2022 and 2021, respectively.

Non-consolidated VIEs

The Company evaluated the nature of its investments in Innoplexus AG (“Innoplexus”), DemeRx NB, Inc. (“DemeRx NB”) and IntelGenx and determined that the investments are VIEs as of the date of the Company’s initial investment through June 30, 2022. The Company is not the primary beneficiary as it did not have the power to direct the activities that most significantly impact the investments’ economic performance and therefore concluded that it did not have a controlling financial interest that would require consolidation as of June 30, 2022 and December 31, 2021.

The Company will reevaluate if the investments meet the definition of a VIE upon the occurrence of specific reconsideration events. The Company accounted for these investments under either the equity method, fair value option, or the measurement alternative included within ASC 321 (See Note 5). As of June 30, 2022, the Company’s maximum exposure for its non-consolidated VIEs was $9.2 million relating to the carrying values in other investments and other investments held at fair value and $7.0 million relating to the carrying value in long term notes receivable – related party. As of December 31, 2021, the Company’s maximum exposure for its non-consolidated VIEs was $11.6 million relating to the carrying values in its other investments and $3.8 million relating to the carrying value in short term notes receivable—related party.

5. Equity Method Investments and Other Investments

Equity Method Investments

As of June 30, 2022 and December 31, 2021, the Company accounted for the following investments in the investee’s common stock under the equity method (amounts in thousands):

		As of June 30, 2022				As of December 31, 2021
	Date First	Common Stock		Carrying		Common Stock		Carrying
Investee	Acquired	Ownership %		Value		Ownership %		Value
Innoplexus A.G.	August 2018	35.0%		$	—	35.0%		$	—
COMPASS Pathways plc	December 2018	22.5%			1,162	22.8%			16,131
GABA Therapeutics, Inc	November 2020	7.5%	(1)		—	7.5%	(1)		—
Total				$	1,162			$	16,131

(1)The Company is deemed to have significant influence over this entity through its total ownership interest in the entity’s equity, including the Company’s investment in the respective entity’s preferred stock, described below in Other Investments.

COMPASS Pathways plc

COMPASS Pathways plc ("COMPASS") is a mental health care company dedicated to pioneering the development of a new model of psilocybin therapy with its product COMP360. The Company first acquired investments in COMPASS in December 2018.

Equity Investment

Through a series of open market transactions between November 23, 2021 and December 7, 2021, the Company purchased an additional 1,490,111 of COMPASS ADSs at an aggregate purchase price of $47.4 million. The additional shares acquired resulted in an increase in

19

the Company’s ownership of COMPASS ADSs to 22.8%. The Company applied the cost accumulation model and recorded its investment at cost. At the date of the investment, a basis difference was identified as the cost basis of the Company’s investment in COMPASS exceeded the Company’s proportionate share of the underlying net assets in COMPASS. The Company concluded that the basis differences were primarily attributable to COMPASS’s IPR&D associated with COMP360, a psilocybin therapy, which COMPASS recently completed a Phase IIb clinical trial for. As the Company’s investment in COMPASS did not meet the definition of a business due to substantially all of the estimated fair value of the gross assets being concentrated in COMP360 and the associated IPR&D, the basis differences were attributable to the IPR&D with no alternative future use, and were immediately expensed at the time of the additional investment. As of June 30, 2022, the Company owned 22.5% of COMPASS ADS. Based on quoted market prices, the market value of the Company’s ownership in COMPASS was $103.5 million as of June 30, 2022.

Upon the completion of the COMPASS IPO and through June 30, 2022, the Company is deemed to continue to have significant influence over COMPASS primarily through its ownership interest in COMPASS’ equity and the Company's representation on COMPASS board of directors. Accordingly, the Company’s investment in COMPASS’ ADS was accounted for in accordance with the equity method through June 30, 2022.

During the three months ended June 30, 2022 and 2021, the Company recognized its proportionate share of COMPASS’ net loss of $4.7 million and $2.1 million, respectively, as losses from investments in equity method investees, net of tax on the condensed consolidated statements of operations. During the six months ended June 30, 2022 and 2021, the Company recognized its proportionate share of COMPASS' net loss of $9.5 million and $2.1 million, respectively, as losses from investments in equity method investees, net of tax on the condensed consolidated statements of operations.

Other Investments

The Company has accounted for its other investments that do not have a readily determinable fair value under the measurement alternative. As of June 30, 2022 and December 31, 2021, the carrying values of other investments, which consisted of investments in the investee’s preferred stock and common stock not in the scope of ASC 323 were as follows (in thousands):

	June 30,		December 31,
	2022		2021
GABA Therapeutics, Inc.	$	7,865	$	10,260
DemeRx NB, Inc.		1,024		1,024
Juvenescence Limited		344		344
Total	$	9,233	$	11,628

The Company’s investments in the preferred stock of Neuronasal (through May 2021), Innoplexus, GABA, and DemeRx NB are not considered as in-substance common stock due to the existence of substantial liquidation preferences and therefore did not have subordination characteristics that were substantially similar to the common stock. Although the Company’s investment in Juvenescence Limited (“Juvenescence”) is in common stock, it is not able to exercise significant influence over the operating and financial decisions of Juvenescence. The Company concluded that its ownership interests in above Other Investments do not have a readily determinable fair value and are accounted for under the measurement alternative. Under the measurement alternative, the Company measured its other investments at cost, less any impairment, plus or minus, if any, observable price changes in orderly transactions for an identical or similar investment of the same issuer.

During the three and six months ended June 30, 2022 and 2021 there were no observable changes in price recorded related to the Company’s Other Investments.

During the three and six months ended June 30, 2022 and 2021, the Company evaluated all of its other investments to determine if certain events or changes in circumstance during these time periods in 2022 and 2021 had a significant adverse effect on the fair value of any of its investments in non-consolidated entities. Based on this analysis, the Company did not note any impairment indicators associated with the Company’s Other Investments.

Innoplexus AG

Innoplexus is a technology company that provides “Data as a Service” and “Continuous Analytics as a Service” solutions that aims to help healthcare organizations leverage their technologies and expedite the drug development process across all stages—preclinical, clinical, regulatory and commercial. The Company first acquired investments in Innoplexus in August 2018.

As of December 31, 2020, the Company owned 35.0% of the common stock issued by Innoplexus. The Company has significant influence over Innoplexus through its noncontrolling representation on the investee’s supervisory board. Accordingly, the Company’s investment in Innoplexus’ common stock was accounted for in accordance with the equity method. The Company’s investment in Innoplexus’ preferred

20

stock did not meet the criteria for in-substance common stock. As such, the investment in Innoplexus’ preferred stock was accounted for under the measurement alternative as discussed below.

In February 2021, the Company entered into a Share Purchase and Assignment Agreement (the “Innoplexus SPA”) to sell its shares of common and preferred stock held in Innoplexus to a current investor of Innoplexus (the “Purchaser”) in exchange for an initial purchase price of approximately $2.4 million. In addition, the Company is entitled to receive contingent payments based on the occurrence of subsequent equity transactions or liquidity events at Innoplexus as determined under the Innoplexus SPA.

Pursuant to the Innoplexus SPA, the Purchaser is required to hold a minimum number of shares equivalent to the number of shares purchased from the Company through December 31, 2026. In the event that the Purchaser is in breach of this requirement, the purchaser is required to pay the Company an additional purchase price of approximately $9.6 million. The transaction was accounted for as a secured financing as it did not qualify for sale accounting under ASC Topic 860, Transfers and Servicing (ASC 860), due to the provision under the Innoplexus SPA which constrained the Purchaser from its right to pledge or exchange the underlying shares and provided more than a trivial benefit to the Company. The initial proceeds from the transaction are reflected as a secured borrowing liability of $2.2 million as of June 30, 2022, which is included in Other liabilities in the Company’s condensed consolidated balance sheet. The Company will continue to account for its investment in Innoplexus’ common stock under the equity method of accounting and its investment in Innoplexus’ preferred shares under the measurement alternative.

In addition, the Innoplexus SPA also provides the right for the Company to receive additional consideration with a maximum payment outcome of $22.3 million should the equity value of Innoplexus exceed certain thresholds upon the occurrence of certain events. The Company concluded that this feature met the definition of a derivative which required bifurcation. As the probability of the occurrence of certain events defined in the Innoplexus SPA was less than remote, the Company concluded that the fair value of the embedded derivative ascribed to this feature was de minimis as of June 30, 2022.

The carrying value of the Company’s investment in Innoplexus was zero as of June 30, 2022 and December 31, 2021.

GABA Therapeutics, Inc.

GABA is a California based biotechnology company focused on developing GRX-917 for anxiety, depression and a broad range of neurological disorders. The Company is deemed to have significant influence over GABA through its total ownership interest in GABA’s equity, including the Company’s investment in GABA’s preferred stock, and the Company’s noncontrolling representation on GABA’s board of directors.

Common Stock Investment

The Company’s investment in GABA’s common stock was accounted for in accordance with the equity method. The Company’s investment in GABA’s preferred stock did not meet the criteria for in-substance common stock. As such, the investment in GABA’s preferred stock is accounted for under the measurement alternative as discussed below.

The carrying value of the investment in GABA common stock was reduced to zero as of December 31, 2020 due to IPR&D charges with no alternative future use and remained zero as of June 30, 2022. Accordingly, GABA’s net losses attributable to the Company were determined based on the Company’s ownership percentage of preferred stock in GABA and recorded to the Company’s investments in GABA preferred stock discussed below. During the three months ended June 30, 2022 and 2021, the Company recognized its proportionate share of GABA’s net loss of $1.9 million and $0.4 million as losses from investments in equity method investees, net of tax on the consolidated statements of operations. During the six months ended June 30, 2022 and 2021, the Company recognized its proportionate share of GABA’s net loss of $2.7 million and $1.1 million, respectively, as losses from investments in equity method investees, net of tax on the consolidated statements of operations.

Preferred Stock Investment

In August 2019, GABA and the Company entered into the Preferred Stock Purchase Agreement (the “GABA PSPA”), whereby GABA issued shares of its Series A preferred stock to the Company at a price of approximately $5.5 million. At closing, the Company had an overall ownership interest of over 20% in GABA and a noncontrolling representation on the board. On May 15, 2021, GABA and the Company entered into an Amendment to Preferred Stock Purchase Agreement (the Amended GABA PSPA”) under which the GABA PSPA was amended. Pursuant to the Amended PSPA, GABA issued additional shares of its Series A preferred stock to the Company at a price of approximately $0.6 million. As of June 30, 2022 and December 31, 2021, the investment in GABA’s preferred stock was recorded in Other Investments on the consolidated balance sheets under the measurement alternative under ASC 321.

Pursuant to the GABA PSPA, the Company is obligated to purchase additional shares of Series A preferred stock for up to $10.0 million with the same price per share as its initial investment, upon the achievement of specified contingent clinical development milestones. On April 13, 2021, pursuant to the GABA PSPA, the Company purchased additional shares of Series A preferred stock of GABA, for an aggregate cost of $5.0 million based on the achievement of certain development milestones. On May 21, 2021, the Company exercised its

21

option to purchase additional shares of Series A preferred stock prior to the achievement of certain development milestone for an aggregate cost of $5.0 million. The completion of the Series A Preferred stock purchase in May 2021 was deemed to be a reconsideration event at which point GABA was no longer deemed a VIE as GABA now had sufficient equity at risk to finance its activities through the initial development period without additional subordinated financial support. Entities that do not qualify as a VIE are assessed for consolidation under the voting interest model (“VOE model”). Under the VOE model, the Company consolidates the entity if it determines that it, directly or indirectly, has greater than 50% of the voting shares and that other equity holders do not have substantive voting, participating or liquidation rights. While the Company holds greater than 50% of the outstanding equity interest of GABA, the Company does not have the power to control the entity. Concurrent with the exercise of the option, the Company executed a side letter with the other equity holders of GABA agreeing to forego the rights to additional seats on the board of directors, resulting in the Company lacking the ability to control the investee. The Company concluded that it does not have a controlling financial interest that would require consolidation under the VOE model and accounted for the investments in GABA preferred stock under the measurement alternative per ASC 323.

As of December 31, 2021, the Company completed the purchase of the additional shares of Series A preferred stock for $10.0 million pursuant to the GABA PSPA. Pursuant to the Amended GABA PSPA, the Company is obligated to purchase additional shares of Series A preferred stock from GABA for up to $1.5 million with the same price per share as its initial investment upon the achievement of specified contingent clinical development milestones.

In accordance with the Amended GABA PSPA, the Company also has the option but not the obligation to purchase the aforementioned additional shares of Series A preferred stock at any time prior to the achievement of any milestone at the same price per share as its initial investment. In August 2019, pursuant to the Right of First Refusal and Co-Sale Agreement, the Company has the option but not the obligation to purchase additional shares of common stock for up to $2.0 million from the existing common shareholders.

In November 2020 the Company exercised its option to purchase additional shares of common stock of GABA at a price of approximately $1.8 million pursuant to an Omnibus Amendment Agreement under which the Right of First Refusal and Co-Sale Agreement was amended.

Neuronasal, Inc.

Neuronasal is developing a novel intranasal formulation of N-acetylcysteine (“NAC”) for acute mild traumatic brain injury.

Common Stock Investment

In October 2020, upon the achievement of certain development milestones, the Company made a cash contribution of $0.3 million in exchange for 9.8% of the outstanding common stock of Neuronasal. The carrying value of the investment in Neuronasal common stock was reduced to zero as of December 31, 2020 due to IPR&D charges with no alternative future use. Accordingly, Neuronasal’s net losses attributable to the Company was determined based on the Company’s ownership percentage of preferred stock in Neuronasal and recorded to the Company’s investments in Neuronasal preferred stock discussed below.

On March 10, 2021, upon the achievement of certain development milestones, the Company made another cash contribution of $0.5 million in exchange for 10.8% of the outstanding common stock of Neuronasal. The Company recorded its investment in Neuronasal common stock at the carrying cost basis of $0.5 million. At the date of the investment, a basis difference was identified as the cost basis of the Company’s investment in Neuronasal exceeded the Company’s proportionate share of the underlying net assets in Neuronasal. The Company concluded that the basis differences were primarily attributable to Neuronasal’s IPR&D associated with Neuronasal’s novel intranasal formulation of NAC. As the Company’s investments in Neuronasal did not meet the definition of a business due to substantially all of the estimated fair value of the gross assets being concentrated in NAC, the basis differences were attributable to the IPR&D with no alternative future use, and were immediately expensed on the dates of investments. The Company’s proportionate share of the basis difference exceeded its carrying value of the equity method investment in Neuronasal and as a result, the March 2021 equity investment balance of $0.5 million was reduced to zero. For the three months ended March 31, 2021, the Company recognized losses from investments in equity method investees, net of tax of $0.5 million in association with the basis difference charge in the Company’s consolidated statements of operations.

The Company was deemed to have significant influence over Neuronasal through its total ownership interest in Neuronasal’s equity through the acquisition date of May 17, 2021 (see Note 3), including the Company’s investment in Neuronasal’s preferred stock, and the Company’s noncontrolling representation on Neuronasal’s board of directors. Accordingly, the Company’s investment in Neuronasal’s common stock was accounted for in accordance with the equity method. Immediately prior to the acquisition, the Company recognized its proportionate share of Neuronasal’s year to date net loss of $1.0 million, as losses from investments in equity method investees, net of tax on the consolidated statements of operations.

The Company’s investment in Neuronasal’s preferred stock did not meet the criteria for in-substance common stock. As such, the investment in Neuronasal’s preferred stock was accounted for under the measurement alternative as discussed below.

22

Preferred Stock Investment

In December 2019, Neuronasal and the Company entered into the Neuronasal PSPA and the Neuronasal Secondary Sale Agreement, whereby Neuronasal issued shares of its Series A preferred stock to the Company at a price of approximately $0.5 million. At closing, the Company had a less than 20% of ownership interest in Neuronasal and a noncontrolling representation on the board. In October 2020, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares at a price of approximately $0.8 million. The investment in Neuronasal preferred shares was recorded in Other Investments on the consolidated balance sheets under the measurement alternative under ASC 321 as of June 30, 2022 and December 31, 2021.

In October 2020, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares at a price of approximately $0.8 million upon the achievement of a specified contingent clinical development milestone. On March 10, 2021, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares for approximately $0.8 million based on the achievement of certain development milestones.

On May 17, 2021, pursuant to the Neuronasal PSPA and the Neuronasal Secondary Sale Agreement, the Company, at its sole option, purchased additional shares of Series A preferred stock of Neuronasal for an aggregate cost of $1.0 million. Upon the closing of the purchase on May 17, 2021, the Company obtained a controlling financial interest in Neuronasal. The Company derecognized its other investments in Neuronasal and began to consolidate the operations of Neuronasal into its financial statements. See Note 3, “Acquisitions” for further discussion.

DemeRx NB

In December 2019, the Company jointly formed DemeRx NB with DemeRx. DemeRx and DemeRx NB entered into a Contribution Agreement whereby DemeRx assigned all of its rights, title, and interests in and to all of its assets relating to DMX-1002, Noribogaine, in exchange for shares of common stock of DemeRx NB. DemeRx NB will use the contributed intellectual property to develop Noribogaine. Noribogaine is an active metabolite of ibogaine designed to have a longer plasma half-life and potentially reduced hallucinogenic effects compared to ibogaine.

In connection with the Contribution Agreement, the parties entered into a Series A Preferred Stock Purchase Agreement (the “DemeRx NB PSPA”) pursuant to which the Company purchased shares of Series A preferred stock of DemeRx NB at a purchase price of $1.0 million. At closing, the Company had less than 20% of ownership interest in DemeRx NB and a noncontrolling representation on DemeRx NB's board of directors. The investment in DemeRx NB was recorded in Other Investments on the condensed consolidated balance sheets under the measurement alternative under ASC 321.

Pursuant to the DemeRx NB PSPA, the Company also has the option but not the obligation to purchase additional shares of DemeRX NB's Series A preferred stock at a purchase price of up to an aggregate of $19.0 million with the same price per share as its initial investment in December 2019. As of June 30, 2022, the Company has not exercised its option to purchase any shares of Series A preferred stock of DemeRx NB.

Other Investments Held at Fair Value

IntelGenx Technologies Corp.

IntelGenx is a novel drug delivery company focused on the development and manufacturing of novel oral thin film products for the pharmaceutical market. In March 2021, IntelGenx and the Company entered into the Strategic Development Agreement and Purchaser Rights Agreement (“PPA”). On May 14, 2021, IntelGenx and the Company executed a Securities Purchase Agreement (the “IntelGenx SPA”) after obtaining IntelGenx shareholder approval, whereby IntelGenx issued shares of its common stock and warrants to the Company at a price of approximately $12.3 million. Each warrant (the “Initial Warrants”) entitles the Company to purchase one share at a price of $0.35 per share for a period of three years from the closing of the initial investment in March 2021. Pursuant to the IntelGenx SPA, the Company has the right to purchase (in cash, or in certain circumstances, the Company’s equity) additional units for a period of three years from the closing of the initial investment (the “Additional Unit Warrants”). Each Additional Unit Warrant will be comprised of (i) one share of common stock and (ii) one half of one warrant (the “Additional Warrants”). The price for the Additional Unit Warrants will be (i) until the date which is 12 months following the closing and the purchase does not result in the Company owning more than 74,600,000 common shares of IntelGenx, $0.331 (subject to certain exceptions), and (ii) until the date which is 12 months following the closing and the purchase results in the Company owning more than 74,600,000 common shares of IntelGenx or following the date which is 12 months following the closing regardless of the number of shares held by the Company, the lower of (A) a 20% premium to the volume weighted average price of the common share for the thirty trading days immediately preceding the news release of the additional closing, and (B) $0.50 if purchased in the second year following closing or $0.75, if purchased in the third year following closing. Each Additional Warrant will entitle the Company, for a period of three years from the date of issuance, to purchase one share at the lesser of either (i) a 20% premium to the price of the corresponding additional share, or (ii) the price per share under which shares of IntelGenx are issued under convertible instruments that were outstanding on February 16, 2021, provided that the Company may not exercise Additional Warrants to purchase more than the lesser of (x) 44,000,000 common shares of IntelGenx, and (y) the number of common shares issued by IntelGenx

23

under outstanding convertibles held by other investors as of February 16, 2021. Following the initial closing, the Company held a 25% voting interest in IntelGenx. Pursuant to the PPA, the Company is entitled to designate a number of directors to the IntelGenx’s board of directors in the same proportion as the shares of common stock held by the Company to the outstanding of IntelGenx common shares.

Pursuant to the Strategic Development Agreement, the Company engages IntelGenx to conduct research and development projects (“Development Project”) using IntelGenx’s proprietary oral thin film technology. Under the terms of the Strategic Development Agreement, the Company can select four (4) program products. As of the effective date of the Strategic Development Agreement, the Company nominated two (2) program products - DMT and Salvinorin A. 20% of any funds that IntelGenx received or will receive through the Company’s equity investment under the IntelGenx SPA will be available to be credited towards research and development services that IntelGenx conducts for the Company under the Development Projects. For the three and six months ended June 30, 2022, the Company recorded an immaterial amount of research & development expense in its condensed consolidated statement of operations in relation to the IntelGenx projects described above. No material research and development services were performed during the three and six months ended June 30, 2021.

The Company has significant influence over IntelGenx through ownership interest in IntelGenx’s equity and the Company’s noncontrolling representation on IntelGenx’s board of directors. The Company qualified for and elected to account for its investment in the IntelGenx common stock under the fair value option. The Company believes that the fair value option better reflects the underlying economics of the IntelGenx common stock investment. The Initial Warrants and Additional Units Warrant, (collectively the “Warrants”) are accounted for at fair value under ASC 321 and recorded in Other investments held at fair value on the consolidated balance sheets. The Company applied a calibrated model and determined that the initial aggregate fair value is equal to the transaction price and recorded the common shares at $3.0 million, the Initial Warrants at $1.2 million and the Additional Unit Warrants at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the consolidated statements of operations. The Company recognizes subsequent changes in fair value of the common shares and the Warrants as a component of other income (expense), net in the consolidated statement of operations. The carrying amount of the investment was reduced to zero as of December 31, 2021, during the three and six months ended June 30, 2022, the Company recognized a $0 mark-to-market (“MTM”) gain/loss in the consolidated statements of operations. The carrying value of the investment remained at zero as of June 30, 2022 and December 31, 2021, respectively.

6. Notes Receivable

Long Term Notes Receivable – Related Party

Loan to IntelGenx Corp.

On March 8, 2021, the Company and IntelGenx entered into a loan agreement under which the Company provided a loan to IntelGenx for an aggregate principal amount of $2.0 million (the “March Term Loan”). Pursuant to the loan agreement, IntelGenx may, by written notice, request an advance up to an additional $0.5 million as an additional term loan if no event of default has occurred as defined in the loan agreement. On May 11, 2021, the Company paid an additional advance of $0.5 million as an additional term loan (the “May Term Loan”, and together with the March Term Loan the “Term Loans”). The Term Loans were originally due to mature 120 days following the special shareholder meeting of IntelGenx Tech Corp. to approve an additional investment in IntelGenx Tech Corp. by the Company ("Maturity Date"). On May 14, 2021, the Company amended the loan agreement under which the Maturity Date will be the first business day following the first closing of a subscription for additional units if the proceeds from such subscription amount to at least $3.0 million. The loan bears an annualized interest rate of 8% and such interest is accrued daily. The principal amount of the Term Loans plus any accrued interest shall become due and payable on the Maturity Date. On September 14, 2021, the Company entered into an amended and restated loan agreement, which among other things, increased the principal amount of loans available to IntelGenx by $6.0 million, up to a total of $8.5 million. The additional loan amount of $6.0 million are funded via two separate tranches of $3.0 million each in the beginning of 2022 and 2023 respectively, subject to certain conditions. In addition, the amendment further extended the Maturity Date to January 5, 2024. The first tranche was funded in January 2022.

Pursuant to the terms of the Term Loans, upon the occurrence of an event of default, the Company may accelerate the Term Loans and declare the principal and any accrued and unpaid interests of the Term Loans to be immediately due and payable. In addition, IntelGenx may prepay the Term Loans in whole or in part at any time without premium or penalty. Any prepayment of the principal shall be accompanied by a payment of interest accrued to date thereon. The Company concluded that these embedded features do not meet the criteria to be bifurcated and separately accounted for as derivatives.

The Company recorded the Term Loans at cost which included the principal balance of the note and accrued interest in Long term notes receivables – related parties on its consolidated balance sheets. As of June 30, 2022, the Term Loans have an outstanding balance of $5.9 million. For the three and six months ended June 30, 2022, the Company recognized interest income of $0.1 million and $0.2 million associated with the Term Loans. For the three and six months ended June 30, 2021, the Company recognized an immaterial amount of interest income associated with the Term Loans. The Company assesses the Term Loans for impairment and records an impairment loss when information becomes available that indicates it is probable that the Term Loans have been impaired and the amount of the loss can be reasonably estimated. As of June 30, 2022, no impairment indicators were present.

Pursuant to the terms of the DemeRx Note, the aggregate principal amount of $1.0 million together with all accrued and unpaid interest and any other amounts payable are due to be paid on the date that is the earlier of (i) 5 years from the initial closing and (ii) the closing of an initial public offering or a deemed liquidation event of DemeRx IB (the “DemeRx Maturity Date”). Pursuant to the terms of the DemeRx Note, DemeRx may, in its sole discretion pay any amount due under the DemeRx Note, in cash or through cancellation shares of common stock of DemeRx IB, par value $0.0001 per share, of the fair market value of such shares.

The Company recorded the DemeRx Note at cost which included the principal balance of the DemeRx Note and accrued interest, net of any payments received, on its condensed consolidated balance sheets. As of June 30, 2022, and December 31, 2021, respectively, the DemeRx Note had an outstanding balance of $1.1 million and $1.1 million, respectively. For the three and six months ended June 30, 2021, the Company recognized an immaterial amount of interest income associated with the DemeRx Note as a component of Other Income in the consolidated statements of operations. For the three and six months ended June 30, 2022, the Company did not earn any interest income associated with the DemeRx Note.

Investment Securities Portfolio - Fair Value Option

The Company elected the fair value option for the securities in the investment portfolio. The fair value is based on quoted market prices, when available. When a quoted market price is not readily available, the Company uses the market price from its last sale of similar assets.

26

The cash and cash equivalents held by the Company are categorized as Level 1 investments as quoted market prices are readily available for these investments. All other investments in the investment portfolio are categorized as Level 2 investments as inputs utilized to fair value these securities are either directly or indirectly observable, such as the market price from the last sale of similar assets.

The Company purchases investment grade marketable debt securities which are rated by nationally recognized statistical credit rating organizations in accordance with its investment policy. This policy is designed to minimize the Company's exposure to credit losses and to ensure that the adequate liquidity is maintained at all times to meet anticipated cash flow needs.

The unrealized gains and losses on the available-for-sale securities, represented by change in the fair value of the investment portfolio, is reported in earnings. Since the investment in the available-for-sale securities are already measured at fair value, no separate credit losses would be recorded in the financials.

Contingent Consideration Liability—Related Parties—Perception, InnarisBio, and TryptageniX

The contingent consideration liability—related parties in the table above relates to milestone and royalty payments in connection with the acquisition of Perception Neuroscience Holdings, Inc. (“Perception”), InnarisBio and TryptageniX. The fair value of the contingent consideration liability—related parties was determined based on significant inputs not observable in the market, which represent Level 3 measurements within the fair value hierarchy. The fair value of the contingent milestone and royalty liabilities was estimated based on the discounted cash flow valuation technique. The technique considered the following unobservable inputs:

• the probability and timing of achieving the specified milestones and royalties as of each valuation date,

• the probability of executing the license agreement,

• the expected first year of revenue, and

• market-based discount rates

The fair value of the contingent milestone and royalty liabilities for InnarisBio was estimated to be $0.1 million and $0.1 million as of June 30, 2022 and December 31, 2021, respectively.

The fair value of the Perception contingent milestone and royalty liabilities could change in future periods depending on prospects for the outcome of R-Ketamine milestone meetings with the FDA or other regulatory authorities, and whether the Company realizes a significant increase or decrease in sales upon commercialization. The most significant assumptions in the discounted cash flow valuation technique that impacts the fair value of the milestone contingent consideration are the projected milestone timing and the probability of the milestone being met. Further, significant assumptions in the discounted cash flow that impacts the fair value of the royalty contingent consideration are the projected revenue over ten years, the timing of royalties on commercial revenue, and the probability of success rate for a commercial R-Ketamine product. The valuations as of June 30, 2022 and December 31, 2021, respectively, used inputs that were unobservable inputs with the most significant being the discount rates for royalties on projected commercial revenue and clinical milestones and probability of success estimates over the following ten years, which represent Level 3 measurements within the fair value hierarchy.

The fair value of the contingent milestone and royalty liabilities for Perception was estimated to be $1.4 million and $1.5 million as of June 30, 2022 and December 31, 2021, respectively.

The fair value of the Perception contingent consideration liability - related parties was calculated using the following significant unobservable inputs:

		June 30, 2022	December 31, 2021
Valuation Technique	Significant Unobservable Inputs	Input Range	Input Range
Discounted cash flow	Milestone contingent consideration:
	Discount rate	15.4%	11.4%
	Probability of the milestone	51.9%	51.9%
Discounted cash flow    with SBM	Royalty contingent consideration:
	Discount rate for royalties	22.5% - 24.0%	19.2% - 20.1%
	Discount rate for royalties on milestones	14.2% - 15.6%	10.9% - 11.8%
	Probability of success rate	26.5% - 51.9%	26.5% to 100.0%

The fair value of the contingent liability for TryptageniX was estimated to be $0.8 million and $0.9 million as of June 30, 2022, and December 31, 2021, respectively. The contingent liability is comprised of R&D milestone success fee payments and royalties payments. The fair value of the success fee liability was estimated based on the scenario-based method within the income approach. The fair value of the contingent liability for TryptageniX was determined based on significant unobservable inputs, including the discount rate, estimated

27

probabilities of success, and timing of achieving certain clinical milestones. The fair value of the royalties liability was determined to be de minimis as the products are in the early stages of development. The Company will continue to assess the appropriateness of the fair value of the contingent liability as the products continue through development.

Warrant Liability

The warrant liability in the table above relates to issued and outstanding warrants to purchase shares of Neuronasal’s common stock acquired in connection with the acquisition of Neuronasal. The warrants were classified within other liabilities in the accompanying condensed consolidated balance sheet as the underlying common stock was determined to be contingently, but not currently, redeemable. The warrant liability was recorded at fair value utilizing the Black-Scholes option pricing model. As summarized below, certain key inputs in connection with the Black-Scholes option pricing model represent Level 3 measurements within the fair value hierarchy. The Black Scholes option pricing model is based on the estimated market value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected dividends, and expected volatility of the price of the underlying common stock. The Company adjusted the carrying value of the warrant to its estimated fair value at each reporting date, with any related increase or decrease in the fair value recorded as a component of other income (expense), net in the condensed consolidated statement of operations.

The fair value of the warrant liability was estimated to be $0.3 million and $0.3 million as of June 30, 2022 and December 31, 2021, respectively.

IntelGenx Common Stock, Initial Warrants and Additional Units Warrant

The Company’s investment in IntelGenx consists of Common Shares, Initial Warrants and Additional Units Warrant (collectively the “Warrants”). The Company determined that the Warrants do not meet the definition of a derivative instrument under ASC 815. The Company has classified the Common Shares as Level 2 assets and the Warrants as Level 3 assets in the fair value hierarchy. The Company determined that the initial aggregate fair value was equal to the transaction price and recorded the Common Shares at $3.0 million, the Initial Warrants at $1.2 million and the Additional Units Warrant at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the consolidated statements of operations. The Warrants are measured at fair value on a quarterly basis and any changes in the fair value will be recorded as a component of other income (expense), net in the condensed consolidated statement of operations.

The fair value of Common Shares is estimated by applying a discount for lack of marketability (“DLOM”) of 5.0% as of December 31, 2021 and June 30, 2022. The Company estimated a DLOM in connection with the valuation of the Common Shares at initial recognition and as of June 30, 2022 to reflect the restrictions associated with the Common Shares. As of June 30, 2022 the only restriction that remains is the unregistered nature of the Common Shares. The fair value of Common Shares, which is included in Other investments held at fair value in the consolidated balance sheet, was zero as of June 30, 2022 and December 31, 2021, respectively.

The Initial Warrant asset was recorded at fair value utilizing the Black-Scholes option pricing model. The Black Scholes option pricing model is based on the estimated market value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected dividends, and expected volatility of the price of the underlying common stock. The expected volatility is based on a peer group volatility which is a Level 3 input within the fair value hierarchy. The fair value of the Initial Warrants, which is included in Other investments held at fair value in the condensed consolidated balance sheet, was zero as of June 30, 2022 and December 31, 2021, respectively.

The fair value of the Additional Units is estimated using a Binomial Lattice in a risk-neutral framework (a special case of the Income Approach). Specifically, the future stock price of the IntelGenx is modeled assuming a Geometric Brownian Motion in a risk-neutral framework. For each modeled future price, the Additional Unit is calculated based on the contractual terms (incorporating any optimal early exercise), and then discounted at the term-matched risk-free rate. Finally, the value of the Additional Units is calculated as the probability-weighted present value over all future modeled payoffs. The fair value of the Additional Units, which is included in Other investments held at fair value in the condensed consolidated balance sheet, was zero as of June 30, 2022 and December 31, 2021, respectively.

During November 2018, the Company executed a terms and conditions agreement (the “Convertible Note Agreement”) under which it was authorized to issue up to €1.0 million or $1.2 million in convertible promissory notes to investors. An investor would become a party to the Convertible Note Agreement and would be issued a convertible promissory note by executing and delivering a subscription form. In November 2018, certain investors subscribed to the Convertible Note Agreement and the Company issued convertible promissory notes in the aggregate principal amount of €0.2 million or $0.2 million.

In October 2020, certain investors subscribed to the Convertible Note Agreement and the Company issued the remainder of the 2018 Convertible Notes in the aggregate principal amount of €0.8 million or $1.0 million (collectively, the “2018 Convertible Notes”). The total aggregate principal amount of the 2018 Convertible Notes is $1.2 million as of December 31, 2020. The 2018 Convertible Notes are non-interest-bearing, unsecured and are due and payable on September 30, 2025, unless previously redeemed, converted, purchased or cancelled (the “Maturity Date”). Each 2018 Convertible Note has a notional value of €1 and is convertible into one share of ATAI Life

30

Sciences AG upon the payment of €17.00. Conversion rights may be exercised by a noteholder at any time prior to maturity, except during certain periods subsequent to the consummation of the IPO. The 2018 Convertible Notes may be declared for early redemption by the noteholders upon occurrence of specified events of default, including payment default, insolvency and a material adverse change in the Company’s business, operations or financial or other condition. Upon early redemption, the conversion right with respect to the 2018 Convertible Notes may no longer be exercised.

In connection with the Convertible Note Agreement, the Company issued convertible notes in the principal amounts of €0.1 million or $0.1 million to the founders of Perception, who are also related parties of the Company in November 2018 (See Note 17). Perception is a biotech firm acquired by the Company on November 5, 2018. Upon the purchase of certain assets of Perception in November 2018, Perception was deemed to have been a VIE, of which the Company is the primary beneficiary (See Note 4).

In addition, in connection with the Convertible Note Agreement, the Company issued convertible notes in the principal amounts of €0.5 million or $0.6 million to Apeiron, the family office of the Company’s co-founder, and €0.3 million or $0.4 million to one other shareholder of the Company and the founder of COMPASS in October 2020.

The Company concluded that both the embedded conversion feature, which is exercisable by the investor at any time during the maturity, and the contingent put option, which would trigger upon the occurrence of an event of default of the 2018 Convertible Notes, do not meet the criteria to be bifurcated and separately accounted for as derivatives and the notes were recorded net of discount and issuance costs, or a reduction to the carrying value of the notes issued in November 2018, with a corresponding adjustment to additional paid in capital. The discount is being amortized using the effective interest method over the period from the respective date of issuance to the Maturity Date.

The Company determined that the October 2020 notes were issued in exchange for services previously provided by the Company’s founders and other shareholders and were fully vested and non-forfeitable upon issuance. These instruments were therefore considered share based compensation awards to non-employees, and the instruments were initially measured and recorded at their grant date fair value based on a Black-Scholes option- pricing model.

The fair value of the October 2020 notes exceeded the principal amount that will be due at maturity. Therefore, at initial recognition, the October 2020 notes were accounted for as convertible debt issued at a substantial premium, such that the face value of the October 2020 Notes are recorded as a liability and the premium was recorded as paid-in capital.

Conversion of 2018 Convertible Promissory Notes - Related Parties

As described in Note 1, the Company undertook a corporate reorganization. Upon the Corporate Reorganization, ATAI Life Sciences N.V became the sole shareholder of ATAI Life Sciences AG. In connection with the Corporate Reorganization, all former shareholders of ATAI Life Sciences AG contributed their shares of ATAI Life Sciences AG to ATAI Life Sciences N.V. and received sixteen shares in ATAI Life Sciences N.V. for every one share of ATAI Life Sciences AG. In 2021, several noteholders elected to convert their convertible promissory notes into shares of ATAI Life Sciences N.V. These investors paid €17.00 per share for an aggregate amount of €5.8 million or $6.9 million in order to convert their convertible promissory notes into ATAI Life Sciences AG common shares, which was in accordance with the original terms of the 2018 Convertible Note Agreements.

In May 2022, an additional noteholder elected to convert some of their convertible promissory notes into shares of ATAI Life Sciences N.V. The investor paid €17.00 per share for the aggregate amount of €1.0 million or $1.1 million in order to convert its convertible promissory notes into ATAI Life Sciences AG common shares, which was in accordance with the original terms of the 2018 Convertible Note Agreements.

The Company accounted for the conversion of the 2018 Convertible Notes as a conversion such that carrying values of these notes were derecognized with an offset to common stock at par of ATAI Life Sciences AG and the excess of the carrying values of these notes over the common stock at par of ATAI Life Sciences AG was recorded as additional paid-in capital. Concurrently, with the conversion of the 2018 Convertible Notes into ATAI Life Sciences AG shares, the shares of ATAI Life Sciences AG that were issued to the noteholders were exchanged for shares of ATAI Life Sciences N.V. through a transfer and sale arrangement. As ATAI Life Sciences AG continued to remain a wholly owned subsidiary of ATAI Life Sciences N.V., the transaction was accounted for as an equity transaction that resulted in no gain or loss recognition.

Perception Convertible Promissory Notes

On March 16, 2020, Perception entered into a convertible promissory note agreement with the Company and other investors, including related parties, which provided for the issuance of convertible notes of $3.9 million (the “Perception Note Purchase Agreement”).

The notes bear interest at an annual rate of 5% and are due and payable on June 30, 2022, unless earlier converted (the “Perception March 2020 Notes”).

31

On December 1, 2020, Perception entered into an additional convertible promissory note agreement (the “Perception December 2020 Convertible Note Agreement”) with the Company and other investors, including related parties, which provided for the issuance of convertible notes of up to $12.0 million. Pursuant to the Perception December 2020 Convertible Note Agreement, the convertible notes are issued in two tranches: (i) up to $7.0 million under the first tranche funding (the “First Tranche Funding”), with $6.2 million and $0.8 million issued in December 2020 and January 2021, respectively, and (ii) up to an additional $5.0 million under the second tranche funding (the “Second Tranche Funding”), was issued in May 2021.

Under the Second Tranche Funding, Perception issued $4.2 million to the Company, $0.2 million to Apeiron, and $0.3 million to Sonia Weiss Pick and Family, and $0.4 million to other investors.

The notes bear interest at an annual rate of 5% and are due and payable on February 28, 2022, unless earlier converted (the “Perception December 2020 Notes” and together with the Perception March 2020 Notes, the “Perception Convertible Notes”).

In the event of a qualified sale of preferred stock resulting in gross proceeds to Perception of at least $5.0 million, all the principal and accrued and unpaid interest under the Perception Convertible Notes will automatically convert, into the same equity securities issued by Perception at a 25% discount from the lowest price of the security issued. In the event that Perception receives upfront proceeds of $5.0 million or more in a licensing transaction, all the principal and accrued and unpaid interest under the Perception convertible notes will automatically convert, into shares of Series A Preferred Stock of Perception at a price per share of $0.75 for the Perception March 2020 Notes and 75% of the fair market value of the Series A Preferred Stock of Perception for the Perception December 2020 Notes. Upon a change in control of Perception, all the principal and accrued and unpaid interest under the Perception Convertible Notes will automatically convert into shares of Series A Preferred Stock of Perception at a price per share of $0.75. The Perception Convertible Notes issued to the Company represent intercompany debt and are eliminated upon consolidation.

The Perception March 2020 Notes contained an embedded conversion features in the event of a qualified financing whereas the Perception December 2020 Notes contained both embedded conversion features in the event of a qualified financing and upon the occurrence of a licensing transaction. The Company concluded that both the embedded conversion features met the definition of embedded derivatives that were required to be bifurcated and accounted for as a separate unit of accounting.

As of December 31, 2020, the Company recorded the fair value of the derivative liabilities of $0.4 million as a liability with the offset being recorded as a debt discount on the issuance dates of the Perception Convertible Notes.

Both the liability and the offsetting debt discount are presented together in convertible promissory notes and derivative liability on the consolidated balance sheets. The resulting debt discount is being amortized to interest expense using the effective interest method over the terms of the Perception Convertible Notes. This interest expense is recorded in other income (expense), net in the consolidated statements of operations. The derivative liabilities are subsequently remeasured to fair value at each reporting date with changes in fair value recognized as a component of other income (expense), net in the consolidated statements of operations.

Upon issuance of the notes under the Second Tranche Funding, the Company recorded the fair value of the derivative liabilities of $0.3 million as a liability with an offset being recorded as a debt discount.

On June 10, 2021, Perception received proceeds of $20.0 million pursuant to the license and collaboration arrangement between Perception and Otsuka Pharmaceutical Co., LTD (“Otsuka”) (See Note 16). Upon receipt of the proceeds, the Perception Convertible Notes automatically converted into 6,456,595 shares of Series A preferred stock of Perception pursuant to their original terms. The Company, Sonia Weiss Pick and Family, Apeiron, and other investors received 5,403,791 shares, 440,415 shares, 27,809 shares and 584,580 shares of Perception Series A preferred stock, respectively, upon conversion of the Perception Convertible Notes. The amounts associated with the shares of Perception Series A preferred stock issued to the Company represent intercompany transactions and are eliminated upon consolidation.

Upon receipt of the proceeds described above, the Company remeasured the derivative liability immediately prior to the conversion of the Perception Notes and recorded a net gain of $41,000 resulting from the change in fair value of the derivative liability in June 2021. The conversion of the Perception December 2020 Notes was accounted for as an extinguishment as the notes were converted pursuant to an embedded conversion feature upon a licensing transaction, which was determined to be a redemption feature. Accordingly, the Company recorded a loss on extinguishment of notes of $0.5 million in the consolidated statements of operations in June 2021. The loss on extinguishment of notes represents the difference between (i) carrying value including derivative liability of the Perception December 2020 Notes of $2.2 million and (ii) the fair value of Perception Series A preferred stock into which the notes converted of $2.7 million.

The conversion of the Perception March 2020 Notes was accounted for as a conversion as the notes converted pursuant to a conversion feature. Accordingly, the Company derecognized the carrying amount of the Perception March 2020 notes issued to Sonia Weiss and Family and other investors in the aggregate amount of $0.6 million with an offset to Series A preferred stock, and no gain or loss was

32

recognized. The shares issued upon conversion of the Perception March 2020 and December 2020 Notes issued to the Company represent an intercompany transaction and, therefore, eliminate in consolidation.

The Company recognized interest expense of $0.1 million, including amortization of debt discount of $93,000 during the three months ended June 30, 2021. The Company recognized interest expense of $0.2 million, including amortization of debt discount of $0.2 million during the six months ended June 30, 2021. As of June 30, 2021, there was no unamortized debt discount due to the conversion of the Perception Convertible Notes into Series A convertible preferred stock of Perception on June 10, 2021. The debt issuance costs associated with the Perception Convertible Notes were not material.

11. Common Stock

In January 2021, pursuant to an additional closing from the common stock issuance in November and December 2020, the Company issued and sold 2,133,328 shares of common stock to Apeiron, for cash proceeds of $12.2 million. In March 2021, the Company issued and sold 13,419,360 shares of common stock to new and existing investors, including related parties, at a price of €9.69 or $11.71 per share, for cash proceeds of $152.2 million, net of issuance costs of $4.9 million.

On June 22, 2021, atai closed the IPO of its common stock on Nasdaq. As part of the IPO, the Company issued and sold 17,250,000 shares of its common stock, which included 2,250,000 shares sold pursuant to the exercise of the underwriters’ over-allotment option, at a public offering price of $15.00 per share. The Company received net proceeds of $231.6 million from the IPO, after deducting underwriters’ discounts and commissions of $18.1 million and offering costs of $9.0 million.

All common stockholders have identical rights. Each share of common stock entitles the holder to one vote on all matters submitted to the stockholders for a vote.

All holders of common stock are entitled to receive dividends, as may be declared by the Company’s supervisory board. Upon liquidation, common stockholders will receive distribution on a pro rata basis. As of June 30, 2022 and December 31, 2021, no cash dividends have been declared or paid.

12. Stock-Based Compensation

Atai Life Sciences 2020 Equity Incentive Plan

Effective August 21, 2020, the Company adopted an equity-based compensation plan, the 2020 Employee, Director and Consultant Equity Incentive Plan (as amended from time to time, “2020 Incentive Plan”). The 2020 Incentive Plan is administered by the Company’s supervisory board. The plan is intended to encourage ownership of shares by employees, directors and certain consultants to the Company in order to attract and retain such individuals, to induce them to work for the benefit of the Company and to provide additional incentive for them to promote the success of the Company.

The Company has reserved up to 22,658,192 shares of common stock, excluding any shares issued under its Hurdle Share Option Program ("HSOP") described below, for issuance to executive officers, directors, other employees and consultants of the Company pursuant to the 2020 Incentive Plan. Shares that are expired, terminated, surrendered, or canceled without having been fully exercised will be available for future awards. As of June 30, 2022, there were no shares available for future grants under the 2020 Incentive Plan and any shares subject to outstanding options originally granted under the 2020 Equity Incentive Plan that terminate, expire or lapse for any reason without the delivery of shares to the holder thereof shall become available for issuance pursuant to the atai Life Sciences 2021 Incentive Award Plan discussed below.

Atai Life Sciences 2021 Incentive Award Plan

Effective April 23, 2021, the Company adopted and the atai shareholders approved the 2021 Incentive Award Plan (“2021 Incentive Plan”). The 2021 Incentive Plan is administered by the Company’s supervisory board. The plan is intended to encourage ownership of shares by employees, directors, and certain consultants to the Company in order to attract and retain such individuals, to induce them to work for the benefit of the Company or of an affiliate and to provide additional incentive for them to promote the success of the Company.

(2)The 21,035,201 outstanding unvested stock options balance includes (a) 16,203,479 that will continue to vest over a one to four-year service period, (b) 2,908,034 that will continue to vest over a three to four-year service period and upon the satisfaction of specified performance-based vesting conditions, (c) 200,000 stock options that will continue to vest over a two-year service period and upon the satisfaction of specified market-based conditions tied to price of the Company's publicly traded shares, (d) 754,910 stock options that will vest immediately upon the satisfaction of specified performance-based vesting conditions, which were not considered probable of achievement as of June 30, 2022, (e) 584,778 stock options that will continue to vest over a three-year service period and upon the satisfaction of specified performance-based vesting conditions, which were not considered probable of achievement as of June 30, 2022, and (f) 384,000 stock options that will vest on the one-year anniversary of the date of grant.

The weighted-average grant-date fair value of options granted during the six months ended June 30, 2022 was $3.48.

The Company estimated the fair value of each stock option using the Black-Scholes option-pricing model on the date of grant. During the six months ended June 30, 2022, the assumptions used in the Black-Scholes option pricing model were as follows:

	June 30,
	2022		2021
Weighted average expected term in years		5.93		3.64
Weighted average expected stock price volatility	70.5%		81.2%
Risk-free interest rate	1.46% - 3.03%		(0.76%) - 1.27%
Expected dividend yield	0%		0%

For the three months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $8.1 million and $20.6 million, respectively. For the six months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $16.7 million and $20.6 million, respectively.

As of June 30, 2022, total unrecognized compensation cost related to the unvested stock-based awards was $87.5 million, which is expected to be recognized over a weighted average period of 2.11 years.

Atai Life Sciences Hurdle Share Option Plan

On August 21, 2020, the Partnership (as defined below) approved and implemented an employee stock option plan for selected executives, employees, and consultants of the Partnership (the so-called Hurdle Share Options Program or “HSOP Plan”), which became effective on January 2, 2021, the date the first grants under the HSOP Plan were made (the “HSOP Options”). This plan is primarily aimed at German-based executives, employees, and consultants of the Company (collectively, the “HSOP Participants”). The purpose of the HSOP Plan is to permit these individuals to indirectly participate in the appreciation in value of the Company through a German law private partnership,

34

ATAI Life Sciences HSOP GbR (the “Partnership”). The HSOP Plan was established under the Partnership Agreement of the Partnership. The HSOP Plan requires the exercise price to be equal to the fair value of the shares on the date of grant.

The Partnership acquired 7,281,376 shares of atai common stock (“HSOP Shares”) pursuant to the HSOP Plan. HSOP Options that are canceled or forfeited without having been fully exercised will be available for future awards. As of June 30, 2022, 132,752 HSOP Options were available for future grants under the HSOP Plan.

The HSOP Plan mimics the economics of a typical stock option plan, however, with the HSOP Shares to which the HSOP Options refer already being issued to the Partnership. Each HSOP Option contains both service and performance-based vesting conditions, including a liquidity-based condition, and gives the holder the option to request the distribution of HSOP Shares under its vested HSOP Options. The nominal amount paid at the grant date is refundable if the HSOP Options do not vest or are forfeited. Otherwise, the nominal amount is refundable until the later of the occurrence of a Liquidity Event (as defined in the “HSOP Plan”) or the exercise date.

The HSOP Shares issued under the HSOP Plan to the Partnership are indirectly owned by HSOP Participants (being the holders of HSOP Options) via their interest in the Partnership. The grantee is required to pay a nominal value (€0.06 per share) for the shares upon grant (“Nominal Upfront Payment”). Accordingly, the HSOP Shares issued to the Partnership and allocated to the HSOP Options holders are not considered outstanding for accounting purposes. Therefore, the Company accounted for the Nominal Upfront Payment as an in-substance early exercise provision under ASC 718 as the nominal amount is deducted from the exercise price upon exercise. As of June 30, 2022, the remaining $0.5 million Nominal Upfront Payment was recorded as an Other liability on the consolidated balance sheets.

HSOP Options

The HSOP Options outstanding noted below consist of service and performance-based options to request the distribution of HSOP Shares. These HSOP Options have a fifteen-year contractual term. These HSOP Options vest over a three to four-year service period, only if and when a “Liquidity Event” (as defined in the Partnership agreement) occurs within fifteen years of the date of grant. If a Change in Control (as defined in the Partnership agreement) or in the event the holder’s service with the Partnership is terminated due to his death or disability by June 30, 2021 or December 31, 2021, an additional 25% or 12.5%, respectively, HSOP Options will accelerate and vest upon the occurrence of the transaction. These awards are subject to the risk of forfeiture until vested by virtue of continued employment or service to the Company.

The liquidity-based performance condition contingent upon the achievement of a Liquidity Event was satisfied in June of 2021, therefore, the Company began recognizing expense for all associated options that were previously deemed improbable of vesting.

The following is a summary of stock option activity for from December 31, 2021 to June 30, 2022:

	Number of Options		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value
Outstanding as of December 31, 2021		7,046,496		6.64		14.01	$	6,961
Granted		—		—		—		—
Exercised		—		—		—		—
Cancelled or forfeited		—		—		—		—
Outstanding as of June 30, 2022		7,046,496	$	6.64		13.51	$	—
Options exercisable as of June 30, 2022		5,537,474	$	6.64		13.51

For the three months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $1.2 million and $16.7 million, respectively. For the six months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $2.5 million and $16.7 million, respectively.

As of June 30, 2022, total unrecognized compensation cost related to the unvested stock-based awards was $5.6 million which is expected to be recognized over a weighted average period of 0.8 years.

Subsidiary Equity Incentive Plans

Certain controlled subsidiaries of the Company adopted their own equity incentive plans (each, an “EIP”). Each EIP is generally structured so that the applicable subsidiary, and its affiliates’ employees, directors, officers and consultants are eligible to receive non-qualified and incentive stock options and restricted stock unit awards under their respective EIP. Standard option grants have time-based vesting requirements, generally vesting over a period of four years with a contractual term of ten years. Such time-based stock options use the Black-Scholes option pricing model to determine grant date fair value. Certain awards issued to employees partially vest on date of grant,

35

then over a three-year service period and upon the satisfaction of specified performance-based vesting conditions, which are not considered probable of achievement as of June 30, 2022.

For the three months ended June 30, 2022 and 2021, the Company recorded share-based compensation expense of $0.2 million and $0.2 million, respectively, in relation to subsidiary EIPs. For the six months ended June 30, 2022 and 2021, the Company recorded share-based compensation expense of $0.4 million and $0.4 million, respectively, in relation to subsidiary EIPs. As of June 30, 2022, there was $8.2 million of total unrecognized stock-based compensation expense related to unvested EIP awards to employees and non-employee directors expected to be recognized over a weighted-average period of approximately 3.0 years.

13. Income Taxes

The Company records its quarterly income tax expense by utilizing an estimated annual effective tax rate applied to its period to date earnings as adjusted for any discrete items arising during the quarter. The tax effect for discrete items are recorded in the period in which they occur. The Company recorded $51,000 and $58,000 income tax expense for the three months ended June 30, 2022 and 2021 respectively. The Company recorded $92,000 and $64,000 income tax expense for the six months ended June 30, 2022 and 2021, respectively. The income tax expense during these periods was primarily driven by current tax on earnings of subsidiaries in Australia, the United States, and the United Kingdom. The primary difference between the effective tax rate and the statutory tax rate is a result of certain income tax deductions available in the United States that are permanent in nature. The Company continues to maintain a full

36

valuation allowance against its deferred tax assets with the exception of certain deferred tax assets relating to certain subsidiaries in Australia, the United States and the United Kingdom.

14. Net Income (Loss) Per Share

Basic and diluted net loss per share attributable to atai stockholders were calculated as follows (in thousands, except share and per share data):

	Three Months Ended June 30,						Six Months Ended June 30,
	2022			2021			2022			2021
Numerator:
Net loss	$	(37,509	)	$	(53,373	)	$	(75,067	)	$	(49,329	)
Net loss attributable to redeemable    noncontrolling interests and noncontrolling    interests		(891	)		(4,912	)		(1,580	)		(1,556	)
Net loss attributable to ATAI Life Sciences    N.V. shareholders - basic and diluted	$	(36,618	)	$	(48,461	)	$	(73,487	)	$	(47,773	)
Denominator:
Weighted average common shares outstanding    attributable to ATAI Life Sciences N.V.    Stockholders - basic and diluted		153,971,202			132,265,075			153,751,456			125,797,732
Net loss per share attributable to ATAI Life    Sciences N.V. shareholders - basic and diluted	$	(0.24	)	$	(0.37	)	$	(0.48	)	$	(0.38	)

HSOP Shares issued to the Partnership and allocated to the HSOP Participants are not considered outstanding for accounting purposes and not included in the calculation of basic weighted average common shares outstanding in the table above because the HSOP Participants have a forfeitable right to distributions until the HSOP Options vest and are exercised, at which time the right becomes nonforfeitable.

The following also represents the maximum amount of outstanding shares of potentially dilutive securities that were excluded from the computation of diluted net income (loss) per share attributable to common shareholders for the periods presented because including them would have been antidilutive:

Potentially dilutive securities to the Company’s common shares:

	As of June 30,
	2022		2021
Options to purchase common stock		34,410,771		23,797,993
HSOP options to purchase common stock		7,046,496		7,281,376
2018 Convertible Promissory Notes - Related Parties (Note 10)		9,561,824		16,000,000
		51,019,091		47,079,369

The remaining 2018 Convertible Notes would be issuable upon the exercise of conversion rights of convertible note holders for 597,614 shares of common stock of ATAI Life Sciences AG, respectively. Upon conversion, it is expected that the remaining 2018 Convertible Notes would be exchanged on a one-for-sixteen basis for shares of ATAI Life Sciences N.V. which is reflected in the table above. See Note 10 for additional discussion.

15. Commitments and Contingencies

Research and Development Agreements

The Company may enter into contracts in the ordinary course of business with clinical research organizations for clinical trials, with contract manufacturing organizations for clinical supplies and with other vendors for preclinical studies, supplies and other services and products for operating purposes.

Leases

As of June 30, 2022, the Company has entered into a five year lease arrangement that has not yet commenced. The Company expects the lease to commence by the end of 2022. This lease will require lease payments over the term of approximately $1.8 million.

37

Indemnification

In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to vendors, lessors, business partners, board members, officers and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company, negligence or willful misconduct of the Company, violations of law by the Company, or intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. No demands have been made upon the Company to provide indemnification under such agreements, and thus, there are no claims that the Company is aware of that could have a material effect on the Company’s consolidated financial statements.

The Company also maintains director and officer insurance, which may cover certain liabilities arising from its obligation to indemnify the Company’s directors. To date, the Company has not incurred any material costs and has not accrued any liabilities in the consolidated financial statements as a result of these provisions.

Contingencies

From time to time, the Company may become involved in legal proceedings arising in the ordinary course of business. The Company is unable to predict the outcome of these matters or the ultimate legal and financial liability, and at this time cannot reasonably estimate the possible loss or range of loss and accordingly has not accrued a related liability. At each reporting date, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company accrues a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, the Company does not record a liability, but instead discloses the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can be made. Legal fees are expensed as incurred. The Company currently believes that the outcome of these legal proceedings, either individually or in the aggregate, will not have a material effect on its consolidated financial position, results of operations or cash flows.

16. License Agreements

Otsuka License and Collaboration Agreement

On March 11, 2021, Perception entered into a license and collaboration agreement (the “Otsuka Agreement”) with Otsuka under which Perception granted exclusive rights to Otsuka to develop and commercialize products containing arketamine, known as PCN-101, in Japan for the treatment of any depression, including treatment-resistant depression, or major depressive disorder or any of their related symptoms or conditions. Under the terms of the Otsuka Agreement, Otsuka received an exclusive right to develop and commercialize products containing PCN-101 in Japan at its own cost and expense. Perception retained all rights to PCN-101 outside of Japan.

Otsuka owed Perception an upfront, non-refundable payment of $20.0 million as of the execution of the Otsuka Agreement. Perception is also entitled to receive aggregate payments of up to $35.0 million if certain development and regulatory milestones are achieved for the current or a new intravenous formulation of a product and up to $66.0 million in commercial milestones upon the achievement of certain commercial sales thresholds. Otsuka is obligated to pay Perception a tiered, double-digit royalty on net sales of products containing PCN-101 in Japan, subject to reduction in certain circumstances.

The Otsuka Agreement will expire upon the fulfillment of Otsuka’s royalty obligations on a product-by-product basis. Otsuka shall have the right to terminate this agreement in its entirety for convenience at any time (a) on ninety (90) days’ prior written notice to Perception if such notice is given before the first regulatory approval of the first licensed product in the Otsuka territory, or (b) on one hundred and eighty (180) days’ prior written notice to Perception if such notice is given on or after the first regulatory approval of the first licensed product in the Otsuka territory. The Otsuka Agreement may be terminated in its entirety at any time during the term upon written notice by either party if the other party is in material breach of its obligations and has not cured such breach within thirty (30) days in the case of a payment breach, or within ninety (90) days in the case of all other breaches.

The Company first assessed the Otsuka Agreement under ASC 808 to determine whether the Otsuka Agreement or units of accounts within the Otsuka Agreement represent a collaborative arrangement based on the risks and rewards and activities of the parties.

The Company concluded that Otsuka is a customer in the context of the Otsuka Agreement and the units of account are within the scope of ASC 606. The Company determined that the combined promise of the exclusive license to PCN-101 and non-exclusive license to conduct clinical trials in Asia are a single performance obligation. The Company determined that the option rights for CMC study data, additional research services and development supply do not represent material rights to Otsuka as these options were issued at standalone selling prices. As such, they are not performance obligations at the outset of the arrangement.

Based on this assessment, the Company concluded three performance obligations existed at the outset of the Otsuka Agreement: (i) the exclusive license to PCN-101 and exclusive license to conduct clinical trials in Japan, (ii) Global Requested Ongoing Clinical Studies (as

38

defined in the Otsuka Agreement) and (iii) Global Ongoing Clinical Studies (as defined in the Otsuka Agreement). The Company determined that the upfront payment of $20.0 million constitutes the transaction price at the outset of the Otsuka Agreement. Future potential milestone payments were fully constrained as the risk of significant revenue reversal related to these amounts has not yet been resolved. The achievement of the future potential milestones is not within the Company’s control and is subject to certain research and development success or regulatory approvals and therefore carry significant uncertainty. The Company will reevaluate the likelihood of achieving future milestones at the end of each reporting period. As all performance obligations will have been satisfied in advance of the achievement of the milestone events, if the risk of significant revenue reversal is resolved, any future milestone revenue from the arrangement will be added to the transaction price (and thereby recognized as revenue) in the period the risk is resolved.

For the three and six months ended June 30, 2022, no additional milestones were achieved under the Otsuka Agreement and the Company did not recognize any revenue associated with the Otsuka Agreement based on performance completed during the period. The remaining deferred revenue balance related to the Otsuka Agreement is not material as of June 30, 2022. Perception satisfied the performance obligation related to the license upon delivery of the license and recognized the amount of $19.7 million allocated to the license as license revenue during the six months ended June 30, 2021. Additionally, the Company recognized license revenues of $0.2 million related to certain research and development services during the three and six months ended June 30, 2022. The Company did not recognize material license revenue during the three and six months ended June 30, 2021.

National University Corporation Chiba University License Agreement

In August 2017, Perception entered into a license agreement (the “CHIBA License”), with the National University Corporation Chiba University (“CHIBA”), relating to Perception’s drug discovery and development initiatives. Under the CHIBA License, Perception has been granted a worldwide exclusive license under certain patents and know-how of CHIBA to research, develop, manufacture, use and commercialize therapeutic products.

During the three and six months ended June 30, 2022 and 2021, respectively, the Company made no material payments pursuant to the CHIBA License.

Allergan License Agreement

In February 2020, Recognify entered into an amended and restated license agreement (the “Allergan License Agreement”), with Allergan Sales, LLC (“Allergan”), under which Allergan granted Recognify an exclusive (non-exclusive as to know-how), sublicensable and worldwide license under certain patent rights and know-how controlled by Allergan to develop, manufacture and commercialize certain products for use in all fields including the treatment of certain diseases and conditions of the central nervous system.

During the three and six months ended June 30, 2022 and 2021, respectively, Recognify made no material payments pursuant to the Allergan License Agreement.

Columbia Stock Purchase and License Agreement

In June 2020, Kures entered into a license agreement with Trustees of Columbia University (“Columbia”), pursuant to which, Kures obtained an exclusive license under certain patents and technical information to discover, develop, manufacture, use and commercialize such patents or other products in all uses and applications (“Columbia IP”). In addition, in consideration for the rights to the Columbia IP, Kures entered into a Stock Purchase Agreement (the “SPA”) with Columbia in contemplation of the license agreement. Pursuant to the SPA, Kures issued to Columbia certain shares of the Kures’ capital stock, representing 5.0% of Kures common stock on a fully diluted basis. Furthermore, the SPA provided that from time to time, Kures shall issue to Columbia additional shares of Kures’ common stock, at a per share price equal to the then fair market value of each such share, which price shall be deemed to have been paid in partial consideration for the execution, delivery and performance by Columbia of the License Agreement, such that the common stock held by Columbia shall equal to 5.0% of the common stock on a fully diluted basis, at all times up to and through the achievement of certain funding threshold.

During the three months ended June 30, 2022, Kures issued shares of Series A-2 Preferred Stock to certain investors upon the achievement of Series A-2 milestone events. Accordingly, the Company issued certain anti-dilution common stock to Columbia worth $0.3 million. The Company expensed the cost incurred for acquiring license as research & development expense at inception. Since, the additional anti-dilution shares were issued as partial consideration towards the same license arrangement, the cost of such additional share was also expensed as research & development expense during the three and six months ended June 30, 2022.

During the three and six months ended 2021, Kures made no material payments in connection with the Columbia agreement.

Accelerate License Agreement

On April 27, 2021, Psyber entered into a license arrangement with Accelerate Technologies Pte. Ltd. (“Accelerate”), whereby Accelerate grants Psyber non-exclusive rights to license and use the technology to commercialize of Psyber’s BCI-enabled companion digital

39

therapeutics in United States of America, Singapore, Member Countries of the European Union, Canada, Australia and New Zealand as a potential treatment for mental health and behavior change, such as substance use disorders including opioid use disorder, mood and anxiety disorders including post-traumatic stress disorder, and treatment-resistant depression.

During the three and six months ended June 30, 2022 and 2021, respectively, Psyber made no material payments pursuant to the Accelerate License agreement.

Dalriada License Agreement

On December 10, 2021, Invyxis, Inc. ("Invyxis"), a wholly owned subsidiary of the Company, entered into an exclusive services and license agreement (the "Invyxis ESLA") with Dalriada Drug Discovery Inc. ("Dalriada"). Under the Invyxis ESLA, Dalriada is to exclusively collaborate with Invyxis to develop products, services and processes with the specific purpose of generating products consisting of new chemical entities. Invyxis will pay Dalriada up to $12.8 million in service fees for research and support services. In addition, Invyxis will pay Dalriada success milestone payments and low single digit royalty payments based on net product sales. Invyxis has the right, but not the obligation, to settle future royalty payments based on net product sales with the Company's common stock. Invyxis and Dalriada will determine the equity settlement based on a price per share determined by both parties.

In January 2022, in accordance with the Invyxis ESLA, Invyxis paid an upfront deposit of $1.1 million, which was capitalized as prepaid research and development expense. The Company will expense the upfront deposit as the services are performed as a component of research and development expense in the consolidated statements of operations. During the three and six months ended June 30, 2022, the Company recorded $1.4 million and $1.8 million as research and development expense, respectively. During the three and six months ended June 30, 2022, Invyxis made no other service fee payments to Dalriada.

Business Overview

We are a clinical-stage biopharmaceutical company aiming to transform the treatment of mental health disorders. We were founded in 2018 as a response to the significant unmet need and lack of innovation in the mental health treatment landscape, as well as the emergence of therapies that previously may have been overlooked or underused, including psychedelic compounds and digital therapeutics. We have built a pipeline of several drug and discovery programs, including eight drug and discovery programs and four enabling technologies, each led by focused teams with deep expertise in their respective fields and supported by our internal development and operational infrastructure. We believe that several of our therapeutic programs’ target indications have potential market opportunities of at least $1 billion in annual sales, if approved. A summary of our clinical and preclinical programs, including related prior evidence in humans based on third-party clinical trials or studies, recent advancements, and upcoming milestones, as applicable, follows under the heading "Our Emerging Clinical and Preclinical Programs" below.

Our business is organized along three strategic pillars:

•Rapid acting intervention: first, second, and third generation compounds that result in rapid-acting improvement of mental health disorders;

•Ongoing digital support: additional care that is provided to patients before, during, and after initial treatment interventions; and

•Biomarker-driven precision mental health: the identification of patient sub-types using biological and digital biomarkers.

Since our inception in 2018, we have focused substantially all of our efforts and financial resources on acquiring and developing product and technology rights, establishing our platform, building our intellectual property portfolio and conducting research and development activities for our product candidates within our atai companies that we consolidate based on our controlling financial interest of such entities. We operate a decentralized model to enable scalable drug or technological development at our atai companies. Our atai companies drive development of our programs and enabling technologies that we have either acquired a controlling or significant interest in or created de novo. We believe that this model provides our development teams the support and incentives to rapidly advance their therapeutic candidates or technologies in a cost-efficient manner. We look to optimize deployment of our capital in order to maximize value for our stakeholders.

We provide our development teams with access to shared services including scientific, intellectual property, clinical and regulatory support. Our global team of subject matter professionals provides deep domain expertise in areas such as mental health drug development and life sciences intellectual property. Development teams have access to relevant expertise specific to each stage of their development. We believe our knowledge and specialization in psychedelics and mental health continuously enhance the quality of the services we provide through the sharing of learnings and experiences across the teams. Examples of specific services we provide include project management, research and development, market strategy and development and corporate finance.

On June 22, 2021, we completed an IPO on Nasdaq, in which we issued and sold 17,250,000 common shares at a public offering price of $15.00 per share, including 2,500,000 shares common shares sold pursuant to the underwriters’ exercise of their option to purchase additional common shares, for aggregate net proceeds of $231.6 million, after deducting underwriting discounts and commissions of $18.1 million and offering costs of $9.0 million. Prior to the IPO, we received gross cash proceeds of $361.5 million from sales of our common shares and convertible notes.

We have incurred significant operating losses since our inception. Our net loss attributable to ATAI Life Sciences N.V. stockholders was $36.6 million and $73.5 million for the three and six months ended June 30, 2022, respectively. Our net loss attributable to ATAI Life Sciences N.V. stockholders was $48.5 million and $47.8 million for the three and six months ended June 30, 2021, respectively. As of June 30, 2022 and December 31, 2021, our accumulated deficit was $431.3 million and $357.8 million, respectively. Our ability to generate product revenue sufficient to achieve profitability will depend substantially on the successful development and eventual commercialization of product candidates at our atai companies that we consolidate based on our controlling financial interest of such entities as determined under the variable interest entity model ("VIE model") or voting interest entity model ("VOE model") . We expect to continue to incur significant expenses and increasing operating losses for at least the next several years.

Our historical losses resulted principally from costs incurred in connection with research and development activities and general and administrative costs associated with our operations. In the future, we intend to continue to conduct research and development, preclinical testing, clinical trials, regulatory compliance, market access, commercialization and business development activities that, together with anticipated general and administrative expenses, will result in incurring further significant losses for at least the next several years. Our operating losses stem primarily from development of our mental health research programs. Furthermore, we expect to incur additional costs associated with operating as a public company, including audit, legal, regulatory, and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums, and investor relations costs. As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our operations through a combination of equity offerings, debt financings, strategic collaborations and alliances or licensing arrangements. Our inability to raise capital as and when needed could have a negative impact on our financial condition and ability to pursue our business strategies. There can be no assurances, however, that our current operating plan will be achieved or that additional funding will be available on terms acceptable to us, or at all.

As of June 30, 2022, we had cash and cash equivalents of $84.1 million and short-term securities of $228.4 million. We believe that our existing cash and short-term securities will be sufficient for us to fund our operating expenses and capital expenditure requirements for at least the next 12 months following the filing of this Quarterly Report. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See “Liquidity and Capital Resources—Liquidity Risk” below.

We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations to date primarily with proceeds from the sale of our common shares and from issuances of convertible notes.

Impactful Capital Allocation and Strategic Value Capture

Consistent with our strategy, we provide the necessary funding and operational support to our programs to maximize their probability of success in clinical development and commercialization. We also regularly review the status of our programs to assess whether there are alternative forms of ownership, partnership or other forms of collaboration that would optimize our economic interests and the success of our programs. To that end, we are focusing on clinical phase programs that we expect to generate meaningful data in the near term, and therefore prioritizing programs that we believe have the highest return potential and value. As a result, in July 2022 through reduction of capital allocation and operational resources, we decided to decelerate some of our drug discovery programs, and Revixia Life Sciences, while evaluating potential divestiture of our equity interests in certain deprioritized programs (such as Neuronasal and DemeRx NB).

Our Emerging Clinical and Preclinical Programs

The table below summarizes the status of our product candidate portfolio as of the filing date of this Quarterly Report. Our pipeline currently consists of therapeutic candidates across multiple neuropsychiatric indications including depression, cognitive impairment associated with schizophrenia, or CIAS, OUD, anxiety, and PTSD. We rely on third parties to conduct our preclinical and clinical trials and, as such, progress and timing of these preclinical and clinical trials and related milestone events, including those discussed in greater detail below, may be impacted by several factors including, but not limited to, changes in existing or future contractual obligations or arrangements with these third parties, geographic developments, such as site locations or regulatory requirements, and other changing circumstances associated with these third parties and the clinical trial sites. See the section titled “Risk Factors—Risks Related to Reliance

43

on Third Parties” in the Form 10-K. We currently hold at least a majority interest, or have options to obtain a majority interest, in each of these atai companies.

The following is a summary of our clinical and preclinical programs, including related prior evidence in humans based on third-party clinical trials or studies, recent advancements, and upcoming milestones, as applicable.

Perception Neuroscience: PCN-101 for TRD

•Product concept: PCN-101 is a parenteral formulation of R-ketamine, a glutamatergic modulator that is a component of racemic ketamine and is being developed as a rapid-acting antidepressant, with the potential to be an at-home non-dissociative alternative to S-ketamine (marketed as SPRAVATO ®).

•Prior evidence in humans: In a third-party clinical trial, another formulation of R-ketamine was observed to produce a rapid and durable response with limited dissociative side effects in patients with TRD. In September 2020, Perception Neuroscience completed a Phase 1 trial of PCN-101 supporting the advancement of PCN-101 into a Phase 2a proof-of-concept trial.

•Upcoming milestones: In September 2021, the Phase 2a proof-of-concept trial of PCN-101 for TRD was initiated. This randomized, double-blind, placebo-controlled Phase 2a proof-of-concept trial is designed to assess the efficacy, safety, dose response, and duration of response in patients with TRD. A topline data readout of this trial is expected by the end of 2022. In December 2021, the FDA gave Investigational New Drug ("IND") clearance to conduct a clinical DDI study of PCN-101, which is being advanced alongside the Phase 2a proof-of-concept trial, to assess the pharmacokinetics of PCN-101 when used concurrently with other drugs. The clinical phase of the DDI study was completed in June 2022. Additionally, the PCN-101 Phase 1 relative bioavailability bridging study of the current intravenous formulation and the subcutaneous formulation supporting at-home use is expected to initiate by the end of the first half of 2023.

Recognify Life Sciences: RL-007 for CIAS

• Product concept: RL-007, a cholinergic, glutamatergic and GABA-B receptor modulator, is an orally available compound that is thought to alter the excitatory/inhibitory balance in the brain to produce pro-cognitive effects. We are developing this compound for the treatment of CIAS.

•Prior evidence in humans: In third-party studies, other formulations of this compound have been shown to improve aspects of cognitive function in both experimental paradigms involving healthy subjects as well as in a Phase 2 trial in patients suffering from diabetic peripheral neuropathic pain. In April 2021, Recognify initiated a Phase 2 proof-of-mechanism study for RL-007 in 32 CIAS patients, after receiving IND clearance from the U.S. Food and Drug Administration to commence clinical trials

44

for the treatment of CIAS. The study was designed to evaluate the effects of RL-007 on safety, tolerability, electroencephalogram-based biomarkers and cognition.

•Recent advancements: In December 2021, we announced positive biomarker data from the Phase 2b proof-of-mechanism study of RL-007 in CIAS patients. RL-007 was well tolerated and demonstrated a clinically meaningful behavioral pro-cognitive profile consistent with previous Phase 1 and 2 trials of this compound. Changes in quantitative electroencephalogram ("qEEG") consistent with a previous Phase 1 trial involving a scopolamine challenge were noted. These results support the progression of RL-007 to a double-blind, placebo-controlled Phase 2b proof-of-concept trial with the goal of demonstrating the pro-cognitive benefit of RL-007 in CIAS.

•Upcoming milestones: We anticipate the Phase 2b proof-of-concept trial to be initiated in the second half of 2022.

GABA: GRX-917 for GAD

•Product concept: GRX-917 is a patent-protected, deuterated version of etifoxine, the latter an approved treatment for anxiety disorders in France and a few other countries. GRX-917 is anticipated to provide the same differentiated clinical profile as etifoxine.

•Prior evidence in humans: Etifoxine has been observed to have the rapid onset of anxiolytic activity of benzodiazepines without their sedating or addicting properties. Furthermore, etifoxine is not associated with abuse, dependence or respiratory depression and has been observed to have no significant impact on motor skills or cognition.

•Recent advancements: In June 2021, GABA initiated a Phase 1 single and multiple ascending dose trial of GRX-917. The ongoing Phase 1 trial is a randomized, double-blind, placebo-controlled study of the safety, tolerability and pharmacokinetics of single and multiple-ascending doses of GRX-917 administered orally to healthy volunteers. As of July 2022, the trial database has been locked.

•Upcoming milestones: Topline data for this trial is expected in the second half of 2022, and the initiation of a proof-of-concept trial in healthy volunteers is anticipated by the end of this year.

DemeRx IB: DMX-1002 for OUD

•Product concept: DMX-1002 is an oral formulation of ibogaine, a cholinergic, glutamatergic and monoaminergic receptor modulator that is a naturally occurring psychedelic product isolated from a West African shrub, that we are developing for the treatment of OUD.

•Prior evidence in humans: In third-party open label studies evaluating other formulations of ibogaine, significant reductions in opioid cravings were observed, both at discharge and at one month post treatment, and were associated with improved mood in patients with OUD.

•Recent advancements: DMX-1002 is being tested in an ongoing Phase 1/2 trial to evaluate its safety, tolerability, pharmacokinetics, and efficacy in recreational drug users and healthy volunteers, to help inform future studies in patients with opioid use disorder.

•Upcoming milestones: We expect safety data from the Phase 1 element of the trial in the second half of 2022.

Kures: KUR-101 for OUD

•Product concept: KUR-101 is an oral formulation of deuterated mitragynine being developed for the treatment of OUD. Mitragynine is a component of the leaves of kratom (Mitragnyna speciosa).

•Prior evidence in humans: Kratom has a long history of traditional medicine use as an analgesic in parts of Southeast Asia, and its use in the United States has increased in recent years, particularly amongst individuals seeking to reduce prescription opioid consumption or manage opioid withdrawal symptoms. Published third-party human data involving isolated mitragynine are limited, but recent mechanistic insights suggest that this compound may be well-suited for the medically assisted therapy of OUD.

•Recent advancements: KUR-101 is being evaluated in a Phase 1 randomized, double-blind, two-part study of the safety, tolerability, pharmacokinetics, analgesic and respiratory effects of KUR-101 in healthy volunteers. Part 1 is a five-cohort, single ascending dose study of KUR-101. Part 2 is a three-period crossover study to compare the analgesic and respiratory effects of a single oral dose of KUR-101, a single oral dose of immediate release oxycodone (OxyNorm®), and a single oral dose of placebo in healthy male volunteers. As of June 2022, Part 1 of the Phase 1 trial has been completed and dosing of subjects in Part 2 has commenced.

•Upcoming milestones: The Phase 1 study designed to evaluate the maximum tolerable dosage is expected to have topline results by the second half of 2022.

45

Viridia Life Sciences: VLS-01 for TRD

•Product concept: VLS-01 is a formulation of DMT, the active moiety of the traditional, hallucinogenic drink ayahuasca. DMT is characterized by an intrinsically short duration of psychedelic effect with a serum half-life estimated at less than 10 minutes. VLS-01 is formulated to provide a psychedelic experience lasting 30 to 45 minutes, thus potentially allowing for a shorter clinic visit compared to many other psychedelic compounds that may require a patient to be monitored for four or more hours.

•Prior evidence in humans: Ayahuasca administration was shown to provide significant antidepressant effects compared with placebo at one, two and seven days after dosing in a double-blind, randomized, placebo-controlled third-party clinical trial in patients with TRD.

•Upcoming milestones: A Phase 1 SAD comparative bioavailability of VLS-01 was initiated in May of this year. The study will compare the relative bioavailability of buccal versus IV formulations, the safety and tolerability of VLS-01 administered by both routes, as well as pharmacodynamics of DMT using qEEG and other measures.

EmpathBio: EMP-01 for PTSD

•Product concept: EMP-01 is an oral formulation of an MDMA derivative being developed for the treatment of PTSD. We are developing EMP-01 for the potential to have an improved therapeutic index compared to racemic MDMA.

•Prior evidence in humans: In a meta-analysis of 21 third-party trials of other formulations of MDMA-combined with psychotherapy for the treatment of PTSD, the benefits of such treatment were statistically significant versus placebo or active placebo-assisted therapy alone. In addition, a recent third-party randomized, double-blind, placebo-controlled phase 3 study with 90 patients with severe PTSD, showed statistically significant reduction in PTSD symptoms in the MDMA-assisted psychotherapy group versus placebo.

•Upcoming milestones: EMP-01 Phase 1 SAD trial recently received ethics committee approval, and central regulatory approval is anticipated in the second half of 2022.

Our Ownership Position in COMPASS

In addition to our emerging clinical and preclinical programs and enabling technologies, we led the Series A financing round in 2018 for COMPASS, co-led their Series B financing round in 2020 and continue to hold a significant equity ownership position in COMPASS. COMPASS is developing its investigational COMP360 psilocybin therapy, which comprises administration of COMP360 with psychological support from specially trained therapists, with an initial focus on TRD. The therapeutic potential of psilocybin administered in conjunction with psychological support has been shown in multiple academic-sponsored studies, which did not involve COMP360, specifically exhibiting rapid reductions in depression symptoms after a single high dose with no SAEs. COMPASS evaluated COMP360 in conjunction with psychological support in a Phase 2b trial that concluded in July 2021 and reported its topline data in November 2021. The Phase 2b trial produced positive results that showed patient improvements beyond reduction of depression symptoms, including in positive affect and quality of life. The randomized, double-blind, dose-ranging study investigated the safety and efficacy of psilocybin therapy in 233 patients, the largest clinical trial with psilocybin to date. In May 2022, COMPASS announced its end-of-phase 2 meeting with the FDA and subsequently submitted its Phase 3 protocols, which are under review. COMPASS expects to start the phase 3 clinical study by the end of 2022. COMPASS commenced a Phase 2 study in anorexia nervosa during 2022. In 2021, COMPASS launched a Phase II clinical trial to assess the safety and tolerability of COMP360 psilocybin therapy in post-traumatic stress disorder, or PTSD. As of June 30, 2022, we beneficially owned 9,565,774 shares representing a 22.5% equity interest in COMPASS. Certain of our founding investors were also seed investors and founders of COMPASS. Our interest in the product candidates of COMPASS is limited to the potential appreciation of our equity interest.

Our Enabling Technologies

We believe our enabling technologies have the potential to support the development of our pipeline and be used as patient support tools. We currently have four enabling technologies housed at our atai companies: Introspect Digital Therapeutics, InnarisBio, EntheogeniX, as well as IntelGenx Technologies, a strategic investment of ours. None of our existing programs were developed using these enabling technologies, and many of these technologies remain in early stage testing and development. We intend to use these enabling technologies to support the future development of our programs. For more information regarding our enabling technologies, see the section titled “Enabling Technologies” in Part 1, Item 1 of our Form 10-K filed with the SEC.

Our Drug Discovery Companies

Although we are currently prioritizing certain clinical phase programs as described further under the section titled “Impactful Capital Allocation and Strategic Value Capture,” above we also believe in the development of innovative and scalable solutions to better meet

46

patient needs. In November 2019, we acquired a majority interest in EntheogeniX Biosciences, a controlled variable interest entity, that is an AI-enabled computational biophysics platform designed to optimize and accelerate drug discovery. PsyProtix, a majority owned subsidiary we launched in February 2021, is developing metabolomics-based biomarkers that stratify TRD patients with the aim to improve patient outcomes through a precision psychiatry approach. In addition, in December 2021 and January 2022, respectively, we announced the launch of two new companies to support this commitment in driving next-generation approaches in the treatment of mental health disorders, TryptageniX and Invyxis. These two companies’ approaches to drug discovery are highly complementary to that of EntheogeniX, our existing AI-enable drug discovery company, of which we acquired a majority interest in 2019. TryptageniX will specialize in both the discovery of new chemical entities (“NCEs”) for our pipeline through bioprospecting and on biosynthesis of our naturally derived development candidates and Invyxis will bring proven medicinal chemistry tools and comprehensive biological screening approaches to our growing enterprise of drug discovery and design. Expanding intellectual property has been essential to our strategy since inception, with key investments made to unlock NCEs. We have already made substantial progress in our drug discovery efforts to date, synthesizing and screening approximately 300 compounds and identifying novel scaffolds that display potential in targeting mental health disorders. For more information regarding our drug discovery companies, see the section titled “Drug Discovery Companies” in Part 1, Item 1 our Form 10-K filed with the SEC.

Financial Overview

Since our inception in 2018, we have focused substantially all of our efforts and financial resources on acquiring and developing product and technology rights, establishing our platform, building our intellectual property portfolio and conducting research and development activities for our product candidates within our atai companies that we consolidate based on our controlling financial interest of such entities. We operate a decentralized model to enable scalable drug or technological development at our atai companies. Our atai companies drive development of our programs and enabling technologies that we have either acquired a controlling or significant interest in or created de novo. We believe that this model provides our development teams the support and incentives to rapidly advance their therapeutic candidates or technologies in a cost-efficient manner. We look to optimize deployment of our capital in order to maximize value for our stakeholders.

Wholly owned subsidiaries and VIEs with greater than 50% ownership and deemed control are consolidated in our financial statements, and our net income (loss) is reduced for the non-controlling interest of the VIE’s share, resulting in net income (loss) attributable to atai stockholders.

Investments, where we have ownership in the underlying company’s equity greater than 20% and less than 50%, or where we have significant influence, are recorded under the equity method. We then record losses from investments in equity method investees, net of tax, for our proportionate share of the underlying company’s net results until the investment balance is adjusted to zero. If we make subsequent additional investments in that same company, we may record additional gains(losses) based on changes to our investment basis and also may record additional income(loss) in equity method investments.

We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations to date primarily with proceeds from the sale of our common shares and from issuances of convertible notes.

Factors Affecting our Results

We believe that the most significant factors affecting our results of operations include:

Research and Development Expenses

Our ability to successfully develop innovative product candidates through our programs will be the primary factor affecting our future growth. Our approach to the discovery and development of our product candidates is still being demonstrated. As such, we do not know whether we will be able to successfully develop any of our product candidates. Developing novel product candidates requires a significant investment of resources over a prolonged period of time, and a core part of our strategy is to continue making sustained investments in this area. We have chosen to leverage our platform to initially focus on advancing our product candidates in the area of mental health.

All of our product candidates are still in development stages, and we have incurred and will continue to incur significant research and development costs for preclinical studies and clinical trials. We expect that our research and development expenses will constitute the most substantial part of our expenses in future periods in line with the advancement and expansion of the development of our product candidates.

Acquisitions/Investments

To continue to grow our business and to aid in the development of our various product candidates, we are continually acquiring and investing in companies that share our common goal towards advancing transformative treatments, including psychedelic compounds and digital therapeutics, for patients that suffer from mental health disorders.

Acquisition of In-Process Research and Development Expenses

47

In an asset acquisition, including the initial consolidation of a VIE that is not a business, acquired in-process research and development, or IPR&D, with no alternative future is charged to the consolidated statements of operations as a component of operating expenses at the acquisition date.

Since inception, we have grown primarily by continually acquiring and investing in other companies. Our IPR&D expenses for the three and six months ended June 30, 2022, were $0.4 million and $0.4 million, respectively, representing 1% and 0.5%, respectively, of our total operating expenses. Our IPR&D expenses for the three and six months ended June 30, 2021 were $8.0 million and $9.0 million, respectively, representing 13.0% and 11.6%, respectively, of our total operating expenses. As we continue to acquire and invest in companies, we expect our IPR&D expenses to increase.

Stock-Based Compensation

In August 2020, we adopted the 2020 Equity Incentive Plan (the “2020 Incentive Plan”) and the Hurdle Share Option Plan (the “HSOP Plan”), which allowed us to grant stock-based awards to executive officers, directors, employees and consultants. Prior to our IPO, we issued stock options that vest over a two to four-year service period, only if and when a “Liquidity Event” (as defined in the plans) occurs, with accelerated vesting if a Liquidity Event occurred by specified dates. Upon the closing of our IPO, the stock-based award vesting contingent upon a Liquidity Event was no longer deferred.

Effective April 23, 2021, we adopted and our shareholders approved the 2021 Incentive Award Plan (the “2021 Incentive Plan”). The 2021 Incentive Plan enables us to grant incentive stock options or nonqualified stock options, restricted stock awards and other stock-based awards to our executive officers, directors and other employees and consultants. Any shares subject to outstanding options originally granted under the 2020 Incentive Plan that terminate, expire or lapse for any reason without the delivery of shares to the holder thereof shall become available for issuance pursuant to the 2021 Incentive Plan. For the three months ended June 30, 2022 and 2021, we incurred $9.5 million and $37.5 million of stock-based compensation expense, respectively. For the six months ended June 30, 2022 and 2021, we incurred $19.7 million and $37.7 million of stock-based compensation expense, respectively.

Impact of COVID-19

The COVID-19 pandemic has continued to present global public health and economic challenges. Although some research and development timelines have been impacted by delays related to the COVID-19 pandemic, we have not experienced material financial impacts on our business and operations as a result. The full extent to which the COVID-19 pandemic will continue to directly or indirectly impact our results of operations and financial condition, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, the success or failure of ongoing vaccination programs worldwide, the emergence and spread of additional variants of COVID-19, as well as the overall impact on local, regional, national and international markets and the global economy. We continue to monitor the impact of the COVID-19 pandemic on our employees and business, including working remotely on a part or full time basis, and have, and will continue to, undertake business continuity measures to mitigate potential disruption to our operations and safety of our employees. For a discussion of the risks related to COVID-19 and impact to our Company’s business and operations, including our research and development programs and related clinical trials, refer to the section titled “Risk Factors” in Part I, Item 1A of the Form 10-K.

Basis of Presentation and Consolidation

Since our inception, we have created wholly owned subsidiaries or made investments in certain controlled entities, including partially-owned subsidiaries for which we have majority voting interest under the VOE model or for which we are the primary beneficiary under the VIE model, which we refer to collectively as our consolidated entities. Ownership interests in entities over which we have significant influence, but not a controlling financial interest, are accounted for as cost and equity method investments. Ownership interests in consolidated entities that are held by entities other than us are reported as redeemable convertible noncontrolling interests and noncontrolling interests in our condensed consolidated balance sheets. Losses attributed to redeemable convertible noncontrolling interests and noncontrolling interests are reported separately in our condensed consolidated statements of operations.

Components of Our Results of Operations

Revenue

On March 11, 2021, Perception Neuroscience, Inc. (“Perception”) entered into a license and collaboration agreement (the "Otsuka Agreement"), with Otsuka Pharmaceutical Co., LTD (“Otsuka”), under which we granted exclusive rights to Otsuka to develop and commercialize certain products containing arketamine in Japan for the treatment of depression and other select indications. Perception received an upfront, non-refundable payment of $20.0 million in June 2021 and we are also eligible to receive up to $35.0 million if certain development and regulatory milestones are achieved and up to $66.0 million in commercial milestones upon the achievement of certain commercial sales thresholds. Perception is eligible to receive tiered, royalties ranging from low-teens to high-teens on net sales of licensed products subject to reduction in certain circumstances.

48

We recognized $0.2 million and $0.2 million of license revenue for the three and six months ended June 30, 2022, respectively. The remaining deferred revenue balance related to the Otsuka Agreement is not material as of June 30, 2022. To date, there have been no milestones achieved under the Otsuka Agreement. Perception satisfied the performance obligation related to the license upon delivery of the license and recognized the amount of $19.7 million allocated to the license as license revenue during the six months ended June 30, 2021. Additionally, we recognized revenues of $0.2 million related to certain research and development services during the six months ended June 30, 2021.

For the foreseeable future, we may generate revenue from reimbursements of services under the Otsuka Agreement, as well as milestone payments under our current and/or future collaboration agreements. We do not expect to generate any revenue from the sale of products unless and until such time that our product candidates have advanced through clinical development and regulatory approval, if ever. We expect that any revenue we generate, if at all, will fluctuate from year-to-year as a result of the timing and amount of payments relating to such services and milestones and the extent to which any of our products are approved and successfully commercialized. Our ability to generate future revenues will also depend on our ability to complete preclinical and clinical development of product candidates or obtain regulatory approval for them.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our discovery efforts and the development of our product candidates, which include:

•employee-related expenses, including salaries, related benefits and stock-based compensation, for employees engaged in research and development functions;

•expenses incurred in connection with the preclinical and clinical development of our product candidates, including our agreements with third parties, such as consultants and contract research organizations (“CROs”);

•expenses incurred under agreements with consultants who supplement our internal capabilities;

•the cost of lab supplies and acquiring, developing and manufacturing preclinical study materials and clinical trial materials;

•costs related to compliance with regulatory requirements;

•facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other operating costs; and

•payments made in connection with third-party licensing agreements.

Research and development costs, including costs reimbursed under the Otsuka Agreement, are expensed as incurred, with reimbursements of such amounts being recognized as revenue. We account for nonrefundable advance payments for goods and services that will be used in future research and development activities as expenses when the service has been performed or when the goods have been received.

Our direct research and development expenses are tracked on a program-by-program basis for our product candidates and consist primarily of external costs, such as fees paid to outside consultants, CROs, contract manufacturing organizations (“CMOs”) and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. Our direct research and development expenses by program also include fees incurred under third-party license agreements.

We do not allocate internal research and development expenses consisting of employee and contractor-related costs, to specific product candidate programs because these costs are deployed across multiple product candidate programs under research and development and, as such, are separately classified.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will continue to increase for the foreseeable future in connection with our planned preclinical and clinical development activities in the near term and in the future.

The successful development of our product candidates is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the remainder of the development of these product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from our product candidates. This is due to the numerous risks and uncertainties associated with developing products, including the uncertainty of whether (i) any clinical trials will be conducted or progress as planned or completed on schedule, if at all, (ii) we obtain regulatory approval for our product candidates and (iii) we successfully commercialize product candidates.

49

Acquisition of In-Process Research and Development Expenses

Acquisition of IPR&D expenses consist of acquired in-process research and development with no future alternative use based on the probability of clinical success.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our executive, finance, corporate and business development and administrative functions, professional fees for legal, patent, accounting, auditing, tax and consulting services, travel expenses and facility-related expenses, which include allocated expenses for rent and maintenance of facilities, advertising, and information technology-related expenses.

We expect that our general and administrative expenses will increase in the future as we increase our general and administrative headcount to support our continued research and development and potential commercialization of our product candidates. We also have incurred increased expenses associated with being a public company, including increased costs for accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance costs, and investor and public relations costs.

Other Income (Expense), Net

Interest Income

Interest income consists of interest earned on cash balances held in interest-bearing accounts and interest earned on notes receivable. We expect that our interest income will fluctuate based on the timing and ability to raise additional funds as well as the amount of expenditures for our research and development of our product candidates and ongoing business operations.

Change in Fair Value of Contingent Consideration Liability—Related Parties

Changes in fair value of contingent consideration liability—related parties, consists of subsequent remeasurement of our contingent consideration liability—related parties with Perception, TryptageniX and InnarisBio for which we record at fair value. See “—Liquidity and Capital Resources—Indebtedness” below for further discussion of our contingent consideration liability—related parties.

Change in Fair Value of Derivative Liability

Changes in fair value of derivative liability consists of subsequent remeasurement of our derivative liability relating to certain embedded features contained in the Perception convertible promissory notes for which we record at fair value. The Perception convertible promissory notes were converted during June 2021. See “—Liquidity and Capital Resources—Indebtedness” below for further discussion the Perception convertible promissory notes.

Unrealized Loss on Other Investments Held at Fair Value

In May 2021, we received IntelGenx common shares, warrants and additional unit warrants for a price of approximately $12.3 million. We determined that the initial aggregate fair value is equal to the transaction price and recorded the common shares at $3.0 million, the warrants at $1.2 million and the additional unit warrants at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the condensed consolidated statements of operations. Subsequently, changes in fair value of the common shares, the warrants and additional unit warrants are recorded as a component of other income (expense), net in the condensed consolidated statement of operations.

Loss on Conversion of Convertible Promissory Notes

In June 2021, upon the funding of the Otsuka Agreement, the Perception convertible promissory notes were converted into Perception Series A preferred stock. The loss represents the difference between (i) carrying value including derivative liability of the Perception December 2020 Notes of $2.2 million and (ii) the fair value of Perception Series A preferred stock into which the notes converted of $2.7 million.

Change in Fair Value of Warrant Liability

Changes in fair value consist of subsequent remeasurement of our warrant liability relating to issued and outstanding warrants to purchase shares of Neuronasal's common stock acquired in connection with the acquisition of Neuronasal in May 2021.

Gain on Consolidation of a Variable Interest Entity

Gain on consolidation of a variable interest entity resulted from the purchase of additional shares of Neuronasal in May 2021. The gain was calculated as the sum of the consideration paid of $1.0 million, the fair value of the noncontrolling interest issued of $3.0 million, the carrying value of our investments in Neuronasal’s common stock and preferred stock prior to May 2021 of $0.8 million, less the fair value of identifiable net assets acquired of $8.3 million.

50

Change in Fair Value of Securities carried at Fair Value

Changes in fair value of securities consists of changes in fair value of available for sale securities. We first purchased securities in January 2022.

Foreign exchange gain (loss), net

Foreign exchange gain (loss), net consists of the impact of changes in foreign currency exchange rates on our foreign exchange denominated assets and liabilities, relative to the U.S. dollar. The impact of foreign currency exchange rates on our results of operations fluctuates period over period based on our foreign currency exposures resulting from changes in applicable exchange rates associated with our foreign denominated assets and liabilities.

Other Income (Expense), net

Other income (expense), net consists principally of interest expense and impairment related to our other investments.

Provision For Income Taxes

For our consolidated entities, deferred income taxes are provided for the effects of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax purposes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

We regularly assess the need to record a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Accordingly, we maintain a full valuation allowance against net deferred tax assets for all entities except for certain subsidiaries in Australia, the United States, and the United Kingdom as of June 30, 2022 which primarily relate to German and international tax loss carryforwards. In assessing the realizability on deferred tax assets, we consider whether it is more-likely-than-not that some or all of deferred tax assets will not be realized. The future realization of deferred tax assets is subject to the existence of sufficient taxable income of the appropriate character (e.g., ordinary income or capital gain) as provided under the carryforward provisions of local tax law. We consider the scheduled reversal of deferred tax liabilities (including the effect in available carryback and carryforward periods), future projected taxable income, including the character and jurisdiction of such income, and tax-planning strategies in making this assessment.

Unrecognized tax benefits arise when the estimated benefit recorded in the financial statements differs from the amounts taken or expected to be taken in a tax return because of the considerations described above. As of June 30, 2022 and December 31, 2021, we had no unrecognized tax benefits.

Losses from Investments in Equity Method Investees, Net of Tax

Losses from investments in equity method investees, net of tax consists of our share of equity method investees losses on the basis of our equity ownership percentage, IPR&D charges resulting from basis differences and impairment related to our equity method investments.

Net Loss Attributable to Redeemable Noncontrolling Interests and Noncontrolling Interests

Net loss attributable to redeemable noncontrolling interests and noncontrolling interests in our consolidated statements of operations is a result of our investments in certain of our consolidated VIEs, and consists of the portion of the net loss of these consolidated entities that is not allocated to us. Net losses in consolidated VIEs are attributed to redeemable noncontrolling interests and noncontrolling interests considering the liquidation preferences of the different classes of equity held by the shareholders in the VIE and their respective interests in the net assets of the consolidated VIE in the event of liquidation, and their pro rata ownership. Changes in the amount of net loss attributable to redeemable noncontrolling interests and noncontrolling interests are directly impacted by changes in the net loss of our VIEs and our ownership percentage changes.

Other		98			56		42			75.0	%
Total research and development expenses	$	17,949		$	16,026	$	1,923			12.0	%

Research and development expenses were $17.9 million for the three months ended June 30, 2022, compared to $16.0 million for the three months ended June 30, 2021. The increase of $1.9 million was primarily attributable to a $4.7 million increase of direct costs at the platform companies as discussed below, partially offset by a $3.1 million decrease in personnel costs, which included a $5.0 million decrease in stock-based compensation.

The $1.2 million increase in direct costs for PCN-101 was primarily due to an increase of $0.8 million in clinical costs, $0.3 million increase in manufacturing expenses and $0.3 million of increased personnel costs, which included a $0.2 million increase in stock-based compensation.

The direct costs of $1.4 million for Invyxis relate to preclinical and discovery activities.

The $0.8 million increase in direct costs for KUR-101 was primarily due to a $0.9 million increase in clinical costs, offset by $0.1 million decrease in preclinical activities and personnel costs.

The $0.8 million increase indirect costs for EMP-001 was primarily due to a $0.9 million increase in clinical and preclinical activities cost, offset by a $0.1 million decrease in manufacturing costs.

The increase of direct costs for RLS-01 by $0.8 million was primary attributable to manufacturing and preclinical costs.

The slight reduction of direct costs for the DMX-1002 program is a result of a $0.4 million decrease in manufacturing and preclinical activities and a $0.3 million increase in clinical development costs.

The direct costs of $0.5 million for TryptageniX relate to preclinical and discovery activities.

The $0.3 million increase in direct costs for EntheogeniX was primarily due to a $0.4 million increase in preclinical activities cost, partially offset by a $0.1 million decrease in manufacturing costs.

The $0.4 million decrease in direct costs for the RL-007 program relates to a reduction in clinical costs.

The $0.06 million decrease in direct costs for InnarisBio relates to a $0.2 million decrease in preclinical activities cost, mostly offset by a $0.14 million increase in manufacturing costs.

The $0.8 million decrease in direct costs for VLS-01 was primarily due to a $0.8 million decrease in manufacturing costs. The decrease in manufacturing costs is primarily attributable to a credit received pursuant to our Strategic Development Agreement with IntelgenX. Per this agreement, IntelgenX will reimburse atai for specified research and development costs, up to 20% of the proceeds IntelgenX receives

53

from atai for purchases of IntelgenX securities. See Note 5 to our unaudited condensed consolidated financial statements appearing under Part 1, Item 1 for more information.

During the three months ended June 30, 2022, we incurred $0.3 million of direct costs in association with IntroSpect, Psyber, Psyprotix, and Neuronasal; direct costs associated with these programs were related to preclinical development and initial clinical-stage activities.

Acquisition of In-Process Research and Development Expense

	Three Months Ended June 30, (unaudited)
	2022		2021		Change			% Change
	(in thousands, except percentages)
Acquisition of in-process research and development expense by    program:
Kures	$	357	$	—	357			100.0%

Total acquisition of in-process research and development    expense	$	357	$	7,962	$	(7,605	)	-95.5%

Acquisition of in-process research and development expenses was $0.4 million for the three months ended June 30, 2022 , which relates to license costs incurred by Kures. Acquisition of in-process research and development expenses was $8.0 million for the three months ended June 30, 2021, which was primarily due to IPR&D acquired from Neuronasal in May 2021. The acquired IPR&D was considered to have no future alternative use.

General and Administrative Expenses

General and administrative expense was $17.2 million for the three months ended June 30, 2022 compared to $37.3 million for the three months ended June 30, 2021. The decrease of $20.1 million was largely attributable to a decrease of $23.0 million in stock-compensation expense and a $1.5 million decrease in professional and consulting fees, partially offset by a $2.5 million increase in personnel and facilities costs, and a $1.2 million increase in insurance costs.

Interest Income

Interest income for the three months ended June 30, 2022 and 2021 primarily consisted of interest earned on our cash balances and notes receivable during these periods. Interest income did not change materially for the three months ended June 30, 2022 and 2021.

Change in Fair Value of Contingent Consideration Liability—Related Parties

The milestone and royalty payments in relation to the acquisition of Perception, InnarisBio and TryptageniX were recorded at the acquisition date or at the exercise date related to the call option, and is subsequently remeasured to fair value. For the three months ended June 30, 2022, we recognized $0.1 million of income due to the increase in the fair value of our Contingent Consideration Liabilities. We recognized $0.9 million of expense for the three months ended June 30, 2021. The changes in the fair value of the contingent consideration liability were primarily due to updates to certain assumptions used to calculate the Perception contingent consideration liability, such as the discount rate.

Change in Fair Value of Derivative Liability

Changes in fair value of derivative liability consists of subsequent remeasurement of our derivative liability relating to certain embedded features contained in the Perception convertible promissory notes for which we record at fair value. The Perception convertible promissory notes were converted during June 2021. See “—Liquidity and Capital Resources—Indebtedness” below for further discussion the Perception convertible promissory notes.

Change in Fair Value of Warrant Liability

Changes in fair value consist of subsequent remeasurement of our warrant liability relating to issued and outstanding warrants to purchase shares of Neuronasal's common stock acquired in connection with the acquisition of Neuronasal in May 2021. The change in fair value of warrant liability for the three months ended June 30, 2022 and 2021 was not material.

Change in Fair Value of Securities carried at Fair Value

Changes in fair value of securities consists of changes in fair value of available for sale securities. We purchased the securities in January 2022. During the three months ended June 30, 2022, we recognized a loss of $0.6 million relating to the change in fair value of securities.

54

Unrealized Loss on Other Investments Held at Fair Value

In May 2021, we received IntelGenx common stock, warrants and additional unit warrants for a price of approximately $12.3 million. We determined that the initial aggregate fair value is equal to the transaction price and recorded the common shares at $3.0 million, the warrants at $1.2 million and the additional unit warrants at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the condensed consolidated statements of operations. Subsequently, changes in fair value of the common shares, the warrants and additional unit warrants are recorded as a component of other income (expense), net in the condensed consolidated statement of operations. During the three months ended June 30, 2022, we recognized $0 of unrealized loss on other investments held at fair value. During the three months ended June 30, 2021, we recognized $5.5 million of unrealized loss on other investments held at fair value.

Loss on Conversion of Convertible Promissory Notes

Loss on conversion of convertible promissory notes for the three months ended June 30, 2021 was $0.5 million. In June 2021, upon the funding of the Otsuka Agreement, the Perception convertible promissory notes were converted into Perception Series A preferred stock. The loss represents the difference between (i) carrying value including derivative liability of the Perception December 2020 Notes of $2.2 million and (ii) the fair value of Perception Series A preferred stock into which the notes converted of $2.7 million. Upon conversion, no further loss will be recorded.

Gain on Consolidation of a Variable Interest Entity

Gain on consolidation of a variable interest entity for the three months ended June 30, 2021 was $3.5 million. We purchased additional shares of Neuronasal in May 2021 and recognized a gain of $3.5 million. The gain was calculated as the sum of the consideration paid of $1.0 million, the fair value of the noncontrolling interest issued of $3.0 million, the carrying value of our investments in Neuronasal’s common stock and preferred stock prior to May 2021 of $0.8 million, less the fair value of identifiable net assets acquired of $8.3 million. The fair value of the IPR&D acquired of $8.3 million was charged to research and development expense as it had no alternative future use at the time of the acquisition. Upon consolidation, no further gain will be recorded.

Foreign Exchange Gain (Loss), Net

We recorded a gain of $4.9 million related to foreign currency exchange rates for the three months ended June 30, 2022 and a loss of $2.6 million related to foreign currency exchange rate for the three months ended June 30,2021. This was due to the impact of fluctuations in the foreign currency exchange rate between the Euro and the U.S. dollar on our foreign denominated balances.

Other Expense, Net

Other expense, net for the three months ended June 30, 2022 was immaterial. Other expense, net for the three months ended June 30, 2021 was $0.1 million, which primarily consisted of interest expense.

Provision For Income Taxes

We incurred current income tax expense of $51,000 for the three months ended June 30, 2022 compared to $58,000 for the three months ended June 30, 2021. Our current income tax expense relates to book profits and thus taxable profits generated in our United States, Australian, and United Kingdom based subsidiaries.

Losses from Investments in Equity Method Investees

Losses from investment in equity method investees for the three months ended June 30, 2022 and 2021 was $6.7 million and $2.9 million, respectively. Loss from investment in equity method investees represents our share of equity method investee losses on the basis of our equity ownership percentages or based on our proportionate share of the respective class of securities in our other investments in the event that the carrying amount of our equity method investments was zero.

Research and development expenses were $33.4 million for the six months ended June 30, 2022, compared to $21.6 million for the six months ended June 30, 2021. The increase of $11.8 million was primarily attributable to an increase of $9.6 million of direct costs at the platform companies as discussed below and $1.9 million of personnel costs, which included a $1.4 million decrease in stock-based compensation.

The $1.7 million increase in direct costs for PCN-101 was primarily due to an increase of $1.9 million in clinical development costs and $0.3 million increase in personnel cost, offset by a reduction of $0.6 million of preclinical and other expenses.

The $2.1 million increase in indirect costs for EMP-001 was primarily due to a $1.7 million increase in preclinical activities cost and a $0.3 million increase in manufacturing costs.

The $1.3 million increase in direct costs for KUR-101 was primarily due to an increase of $1.1 million in clinical development costs, $0.4 million of preclinical activities, partially offset by a decrease of $0.1 million personnel costs and $0.1 million reduction in manufacturing costs.

The $0.5 million increase in direct costs for VLS-01 was primarily due to a $0.3 million increase in manufacturing costs, a $0.2 million increase in clinical costs.

The direct costs of $1.8 million for Invyxis relate to preclinical and discovery activities.

The reduction of direct costs for the DMX-1002 program of $0.3 million primarily relates to reduced preclinical development costs.

The increase of direct costs for RLS-01 by $1.1 million was primary attributable to manufacturing and preclinical costs.

The $0.4 million reduction in direct costs for the RL-007 program was primarily related to a decrease in clinical costs.

The direct costs of $0.7 million for TryptageniX relate to preclinical and discovery activities.

The $0.4 million increase in direct costs for EntheogeniX was primarily due to a $0.6 million increase in preclinical activities cost, partially offset by a $0.2 million decrease in manufacturing costs.

The $0.2 million increase in direct costs for InnarisBio relate to manufacturing and preclinical activities cost.

57

During the six months ended June 30, 2022, we incurred $0.7 million of direct costs in association with IntroSpect, Psyber, Psyprotix, and Neuronasal ; direct costs associated with these programs were related to preclinical development and initial clinical-stage activities.

Acquisition of in-process research and development expenses was $0.4 million for the six months ended June 30, 2022 ,which relates to license costs incurred by Kures. Acquisition of in-process research and development expenses was $9.0 million for the six months ended June 30, 2021, which was IPR&D acquired from Neuronasal in May 2021 and InnarisBio in March 2021. The acquired IPR&D was considered to have no future alternative use.

General and Administrative Expenses

General and administrative expenses were $35.2 million for the six months ended June 30, 2022 compared to $46.6 million for the six months ended June 30, 2021. The decrease of $11.4 million was largely attributable to a decrease of $16.6 million in stock-compensation expense and a $2.4 million decrease in professional and consulting fees, partially offset by a $3.8 million increase in personnel and facilities costs, a $2.9 million increase in insurance costs and a $0.7 million increase in regulatory fees and supervisory board of directors compensation.

Interest Income

Interest income for the six months ended June 30, 2022 and 2021 primarily consisted of interest earned on our cash balances and notes receivable during these periods. We had interest income for the six months ended June 30, 2022 and 2021 of $0.2 million and $0.1 million, respectively.

Change in Fair Value of Contingent Consideration Liability—Related Parties

The milestone and royalty payments in relation to the acquisition of Perception, InnarisBio and TryptageniX were recorded at the acquisition date or at the exercise date related to the call option, and is subsequently remeasured to fair value. For the six months ended June 30, 2022, we recorded income of $0.1 million due to the increase in the fair value of our Contingent Consideration Liabilities. For the six months ended June 30, 2021, we recognized expense of $0.7 million. The changes in the fair value of the contingent consideration liability were primarily attributable to the Perception contingent consideration. During the six months ended June 30, 2021 we closed the Otsuka Agreement. Prior to closing the Otsuka Agreement, we used a probability weighted approach for the royalty payments, where 80% was applied to the license scenario and 20% was applied to the no-license scenario. As of June 30, 2021, the license transaction had closed and the scenario-based method with 80%/20% probability was no longer used.

Change in Fair Value of Warrant Liability

Changes in fair value consist of subsequent remeasurement of our warrant liability relating to issued and outstanding warrants to purchase shares of Neuronasal's common stock acquired in connection with the acquisition of Neuronasal in May 2021. The change in fair value of warrant liability for the six months ended June 30, 2022 and 2021 was not material.

Change in Fair Value of Securities carried at Fair Value

Changes in fair value of securities consists of changes in fair value of available for sale securities. We purchased the securities in January 2022. During the six months ended June 30, 2022 and 2021, we recognized a loss of $1.3 million and an immaterial change, respectively, relating to the fair value of securities.

Unrealized Loss on Other Investments Held at Fair Value

In May 2021, we received IntelGenx common stock, warrants and additional unit warrants for a price of approximately $12.3 million. We determined that the initial aggregate fair value is equal to the transaction price and recorded the common shares at $3.0 million, the warrants at $1.2 million and the additional unit warrants at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the condensed consolidated statements of operations. Subsequently, changes in fair value of the common shares, the warrants

58

and additional unit warrants are recorded as a component of other income (expense), net in the condensed consolidated statement of operations. During the six months ended June 30, 2022, we recognized $0 of unrealized loss on other investments held at fair value. During the six months ended June 30, 2021, we recognized $5.5 million of unrealized loss on other investments held at fair value.

Loss on Conversion of Convertible Promissory Notes

Loss on conversion of convertible promissory notes for the three months ended June 30, 2021 was $0.5 million. In June 2021, upon the funding of the Otsuka Agreement, the Perception convertible promissory notes were converted into Perception Series A preferred stock. The loss represents the difference between (i) carrying value including derivative liability of the Perception December 2020 Notes of $2.2 million and (ii) the fair value of Perception Series A preferred stock into which the notes converted of $2.7 million. . Upon conversion, no further loss will be recorded.

Gain on Consolidation of a Variable Interest Entity

Gain on consolidation of a variable interest entity for the three months ended June 30, 2021 was $3.5 million. We purchased additional shares of Neuronasal in May 2021 and recognized a gain of $3.5 million. The gain was calculated as the sum of the consideration paid of $1.0 million, the fair value of the noncontrolling interest issued of $3.0 million, the carrying value of our investments in Neuronasal’s common stock and preferred stock prior to May 2021 of $0.8 million, less the fair value of identifiable net assets acquired of $8.3 million. The fair value of the IPR&D acquired of $8.3 million was charged to research and development expense as it had no alternative future use at the time of the acquisition. Upon consolidation, no further gain will be recorded.

Foreign Exchange Gain (Loss), Net

We recorded a gain of $7.0 million related to foreign currency exchange rates for the six months ended June 30, 2022 and a loss of $1.1 million related to foreign currency exchange rates for the six months ended June 30,2021. This was due to the impact of fluctuations in the foreign currency exchange rate between the Euro and the U.S. dollar on our foreign denominated balances.

Other Expense, Net

Other expense, net for the six months ended June 30, 2022 was not material. Other expense, net for the six months ended June 30, 2021 was $0.2 million, which primarily consisted of interest expense.

Provision For Income Taxes

We incurred current income tax expense of $92,000 for the six months ended June 30, 2022 compared to $64,000 for the six months ended June 30, 2021. Our current income tax expense relates to book profits and thus taxable profits generated in our United States, Australian, and United Kingdom based subsidiaries.

Losses from Investments in Equity Method Investees

Losses from investment in equity method investees for the six months ended June 30, 2022 and 2021 were $12.3 million and $4.6 million, respectively. Loss from investment in equity method investees represents our share of equity method investee losses on the basis of our equity ownership percentages or based on our proportionate share of the respective class of securities in our other investments in the event that the carrying amount of our equity method investments was zero.

Liquidity and Capital Resources

Sources of Liquidity

Initial Public Offering

In June 2021, we completed our IPO and issued and sold 17,250,000 of our common shares at a price to the public of $15.00 per share, which included the exercise in full by the underwriters of their option to purchase 2,250,000 additional common shares. We received aggregate net proceeds of $231.6 million, after underwriting discounts and commissions of $18.1 million and offering costs of $9.0 million. As of June 30, 2022, we had cash and cash equivalents of $84.1 million and short-term securities of $228.4 million.

Convertible Promissory Notes

In November 2018, we issued an aggregate principal amount of $0.2 million of convertible notes, or the 2018 Convertible Notes. The 2018 Convertible Notes are non-interest-bearing and have a maturity date of September 30, 2025, unless previously redeemed, converted, purchased or cancelled. In October 2020, we issued an additional principal amount of $1.0 million of the 2018 Convertible Notes. Each note has a face value of €1 and is convertible into one ordinary share of ATAI Life Sciences AG upon the payment of €17.00. In 2021, several noteholders elected to convert their convertible promissory notes into shares of ATAI Life Sciences N.V. These investors paid €17.00 per share for the aggregate amount of €5.8 million or $6.9 million in order to convert their convertible promissory notes into ATAI Life Sciences AG common shares, which was in accordance with the original terms of the 2018 Convertible Note Agreements. In May 2022, an additional noteholder elected to convert some of their convertible promissory notes into shares of ATAI Life Sciences N.V. The

59

investor paid €17.00 per share for the aggregate amount of €1.0 million or $1.1 million in order to convert its convertible promissory notes into ATAI Life Sciences AG common shares. Concurrently, with the conversion of the 2018 Convertible Notes into ATAI Life Sciences AG shares, the shares of ATAI Life Sciences AG that were issued to the noteholders were exchanged for shares of ATAI Life Sciences N.V. through a transfer and sale arrangement such that ATAI Life Sciences AG continued to remain a wholly owned subsidiary of ATAI Life Sciences N.V and the transaction was accounted for as an equity transaction that resulted in no gain or loss recognition. The remaining convertible promissory notes balance as of June 30, 2022 was $0.6 million. In July 2022, an additional noteholder elected to convert some of their convertible promissory notes into shares of ATAI Life Sciences N.V. The investor paid €17.00 per share for an aggregate amount of €3.6 million or $3.6 million in order to convert its convertible promissory notes into ATAI Life Sciences AG common shares. Concurrently, with the conversion of the 2018 Convertible Notes into ATAI Life Sciences AG shares, the shares of ATAI Life Sciences AG that were issued to the noteholders were exchanged for shares of ATAI Life Sciences N.V. through a transfer and sale arrangement.

Investments

While a significant potential source of liquidity resides in our investment in COMPASS ordinary shares, we do not expect that our investment in COMPASS will be a material source of liquidity in the near term. Based on quoted market prices, the market value of our ownership in COMPASS was $103.5 million as of June 30, 2022. As of June 30, 2022, the carrying value of our investment in COMPASS was $1.2 million under the equity method. Through a series of open market transactions between November 23, 2021 and December 7, 2021 we purchased additional equity investments in COMPASS common stock. As of June 30, 2022, our voting interest in COMPASS was 22.5%.

Hercules Term Loan

In August 2022, we entered into a Loan and Security Agreement, with Hercules Capital, Inc. See “ – Liquidity Risks – Indebtedness– Hercules Term Loan” for additional information.

Liquidity Risks

As of June 30, 2022, we had cash and cash equivalents of $84.1 million and short-term securities of $228.4 million. We believe that our cash and cash equivalents will be sufficient to fund our projected operating expenses and capital expenditures through at least the next 12 months from the date of this Quarterly Report.

We expect to incur substantial additional expenditures in the near term to support our ongoing activities. Additionally, we have incurred and expect to continue to incur additional costs as a result of operating as a public company. We expect to continue to incur net losses for the foreseeable future. Our ability to fund our product development and clinical operations as well as commercialization of our product candidates, will depend on the amount and timing of cash received from planned financings.

Our future capital requirements will depend on many factors, including:

•the time and cost necessary to complete ongoing and planned clinical trials;

•the outcome, timing and cost of meeting regulatory requirements established by the FDA, the EMA and other comparable foreign regulatory authorities;

•the progress, timing, scope and costs of our preclinical studies, clinical trials and other related activities for our ongoing and planned clinical trials, and potential future clinical trials;

•the costs of commercialization activities for any of our product candidates that receive marketing approval, including the costs and timing of establishing product sales, marketing, distribution and manufacturing capabilities, or entering into strategic collaborations with third parties to leverage or access these capabilities;

•the amount and timing of sales and other revenues from our product candidates, if approved, including the sales price and the availability of coverage and adequate third party reimbursement;

•the cash requirements for purchasing additional equity from certain of our atai companies upon the achievement of specified development milestone events;

•the cash requirements for developing our programs and our ability and willingness to finance their continued development;

•the cash requirements for any future acquisitions or discovery of product candidates; and

•the time and cost necessary to respond to technological and market developments, including other products that may compete with one or more of our product candidates.

60

A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Further, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans. If we are unable to obtain this funding when needed on acceptable terms or at all, we could be forced to delay, limit or terminate our product development efforts.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through a combination of equity financings, debt financings, collaborations with other companies and other strategic transactions. We do not currently have any committed external source of funds. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Further, our operating plans may change, and we may need additional funds to meet operational needs and capital requirements for clinical trials and other research and development activities. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated product development programs.

In November 2018, we issued an aggregate principal amount of $0.2 million of convertible notes, or the 2018 Convertible Notes. The 2018 Convertible Notes are non-interest-bearing and have a maturity date of September 30, 2025, unless previously redeemed, converted, purchased or cancelled. In October 2020, we issued an additional principal amount of $1.0 million of 2018 Convertible Notes.

Hercules Term Loan

On August 9, 2022 (the “Closing Date”), we, ATAI Life Sciences AG (“ATAI AG” and together with the Company, the “Borrowers”) and certain of our subsidiary guarantors (collectively, the “Subsidiary Guarantors”) entered into a Loan and Security Agreement (the “Loan Agreement”) with Hercules Capital, Inc. (“Hercules”), in its capacity as administrative agent and collateral agent (the “Agent”) and as a lender, and certain other financial institutions that from time to time become parties to the Loan Agreement as lenders (collectively, the “Lenders”).

We have agreed to use the proceeds of the 2022 Term Loan Facility for working capital and general business purposes.

We are permitted to engage in certain specified transactions (subject to mandatory prepayment in certain instances as well as certain limitations, including the pledge of equity interests of certain subsidiaries and VIEs), including but not limited to, (i) entering into non-exclusive and certain specified exclusive licensing arrangements with respect to intellectual property without the consent of the Lenders; and (ii) entering into certain permitted acquisitions.

The 2022 Term Loan Facility will mature on August 1, 2026 (the “Maturity Date”), which may be extended until February 1, 2027 if we achieve certain performance milestones, raise at least $175.0 million of unrestricted new net cash proceeds from certain permitted sources after the Closing Date and prior to June 30, 2024, and satisfy certain other specified conditions. The outstanding principal balance of the 2022 Term Loan Facility bears interest at a floating interest rate per annum equal to the greater of either (i) the prime rate as reported in the Wall Street Journal plus 4.55% and (ii) 8.55%. Accrued interest is payable monthly following the funding of each term loan advance. We may make payments of interest only, without any loan amortization payments, for a period of thirty (30) months following the Closing Date, which period may be extended to (i) thirty-six months if certain additional performance milestones have been achieved; and (ii) forty-two months if certain additional performance milestones have been achieved. At the end of the interest only period, we are required to begin repayment of the outstanding principal of the 2022 Term Loan Facility in equal monthly installments.

As collateral for the obligations under the 2022 Term Loan Facility, we have granted to the Agent for the benefit of the Lenders a senior security interest in substantially all of our, ATAI AG and each Subsidiary Guarantor’s property (including a pledge of equity interests of certain subsidiaries and VIEs), exclusive of intellectual property, with certain limited exceptions set forth in the Loan Agreement.

The Loan Agreement contains customary closing and commitment fees, prepayment fees and provisions, events of default and representations, warranties and affirmative and negative covenants, including a financial covenant requiring us to maintain certain levels of cash in accounts subject to a control agreement in favor of the Agent (the “Qualified Cash”) at all times commencing from the Closing Date, which includes a cap on the amount of cash that can be held by, among others, certain of our foreign subsidiaries in Australia and the United Kingdom. In addition, the financial covenant under the Loan Agreement requires that beginning on the later of (i) July 1, 2023 and (ii) the date on which the aggregate outstanding amount borrowed under the 2022 Term Loan Facility is equal to or greater than $40.0 million, we shall maintain Qualified Cash in an amount no less than the sum of (1) 33% of the outstanding amount under the 2022 Term Loan Facility, and (2) the amount of the Borrowers’ and Subsidiary Guarantors’ accounts payable that have not been paid within 180 days from the invoice date of the relevant account payable, subject to certain exceptions; provided, that the financial covenant shall not apply on any day that our market capitalization is at least $600.0 million measured on a consecutive 10-business day period immediately prior to such date of measurement and tested on a daily basis. Upon the occurrence of an event of default, including a material adverse effect, subject to certain exceptions, on our and ATAI AG’s, taken together, business, operations, properties, assets or financial condition, and subject to any specified cure periods, all amounts owed by us may be declared immediately due and payable by the Lenders. As of the Closing Date, we were in compliance with all applicable covenants under the Loan Agreement.

In addition, we are required to make a final payment fee (the “End of Term Charge”) upon the earlier of (i) the Maturity Date, (ii) the date that we prepay, in full or in part, the principal balance of the 2022 Term Loan Facility, or (iii) the date that the outstanding balance of the 2022 Term Loan Facility becomes due and payable. The End of Term Charge is 6.95% of the aggregate original principal amount of the term loans so repaid or prepaid under the Loan Agreement.

We may, at our option, prepay the term loans in full or in part, subject to a prepayment penalty equal to (i) 2.00% of the principal amount prepaid if the prepayment occurs on or prior to the first anniversary of the Closing Date, (ii) 1.0% of the principal amount prepaid if the prepayment occurs after the first anniversary and on or prior to the second anniversary of the Closing Date, and (iii) 0.5% of the principal amount prepaid if the prepayment occurs after the second anniversary and prior to the Maturity Date.

Material Cash Requirements from Known Contractual and Other Obligations and Commitments

Our commitments and obligations were reported in our Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the Securities and Exchange Commission, or SEC, on March 30, 2022. During the six months ended June 30, 2022, there have been no material changes from the contractual commitments and obligations previously disclosed in our Form 10-K.

Off-Balance Sheet Arrangements

As of June 30, 2022, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K. While we have investments classified as VIEs, their purpose is not to provide off-balance sheet financing.

Recently Adopted Accounting Pronouncements

See Note 2, “Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” to our unaudited condensed consolidated financial statements appearing under Part 1, Item 1 for more information.

Critical Accounting Policies and Estimates

We believe that the assumptions and estimates associated with licenses of intellectual property, research and development expenses, acquisitions and share-based compensation have the greatest potential impact on our financial statements. Therefore, we consider these to be our critical accounting estimates. Our critical accounting policies are detailed in our Form 10-K.

JOBS Act

We are an emerging growth company, as defined in the JOBS Act. We intend to rely on certain of the exemptions and reduced reporting requirements provided by the JOBS Act. As an emerging growth company, we are not required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act, and (ii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis). We have elected to use the extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that (i) we are no longer an emerging growth company or (ii) we affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

As described in Note 2 to our unaudited consolidated financial statements included elsewhere in this Quarterly Report, we have early adopted certain accounting standards, as the JOBS Act does not preclude an emerging growth company from adopting a new or revised accounting standard earlier than the time that such standard applies to private companies. We expect to use the extended transition period for any other new or revised accounting standards during the period in which we remain an emerging growth company.

We will remain an emerging growth company until the earliest to occur of: (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering, or December 31, 2026, (b) in which we have total annual gross revenues of $1.07 billion or more, or (c) in which we are deemed to be a large accelerated filer under the rules of the SEC, which means the market value of our outstanding common shares held by non-affiliates equal or exceeds $700 million as of last business day of our most recently completed second fiscal quarter, and (2) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign currency exchange rates. In addition, our portfolio of notes receivables is exposed to credit risk in the form of non-payment or non-performance. In mitigating our credit risk, we consider multiple factors, including the duration and terms of the note and the nature of and our relationship with the counterparty.

Interest Rate Sensitivity

Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates. As of June 30, 2022, we had cash and cash equivalents of $84.1 million and short-term securities of $228.4 million. We generally hold our cash in interest-bearing demand deposit accounts and short-term securities. Due to the nature of our cash and investment portfolio, a hypothetical 100 basis point change in interest rates would not have a material effect on the fair value of our cash. Our cash is held for working capital purposes. The Company purchases investment grade marketable debt securities which are rated by nationally recognized statistical credit rating organizations in accordance with its investment policy. This policy is designed to minimize the Company's exposure to credit losses and to ensure that the adequate liquidity is maintained at all times to meet anticipated cash flow needs.

64

As of June 30, 2022, we had $0.6 million in convertible promissory notes – related parties, net, which was comprised of non-interest-bearing borrowings under the 2018 Convertible Notes. Based on the principal amounts of the convertible promissory notes and the interest rate assigned to the convertible promissory notes, an immediate 10% change in interest rates would not have a material impact on our convertible promissory notes, financial position or results of operations.

As of June 30, 2022, the carrying amount of our short and long-term notes receivables was an aggregate amount of $7.6 million. Based on the principal amounts of the notes receivable and the interest rates assigned to each note receivable as per their respective contracts, an immediate 10% change in the interest rates would not have a material impact on our notes receivables, financial position or results of operations.

Foreign Currency Exchange Risk

Our reporting and functional currency is the U.S. dollar, and the functional currency of our foreign subsidiaries is generally the respective local currency. The assets and liabilities of each of our foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at each balance sheet date. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component on the condensed consolidated statements of comprehensive loss. Equity transactions are translated using historical exchange rates. Expenses are translated using the average exchange rate during the previous month. Gains or losses due to transactions in foreign currencies are included in interest and other income, net in our condensed consolidated statements of operations.

The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We have experienced and will continue to experience fluctuations in foreign exchange gains and losses related to changes in foreign currency exchange rates. In the event our foreign currency denominated assets, liabilities, revenue, or expenses increase, our results of operations may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business, resulting in unrealized foreign exchange gains or losses. We have not engaged in the hedging of foreign currency transactions to date, although we may choose to do so in the future.

A hypothetical 10% change in the relative value of the U.S. dollar to other currencies during any of the periods presented would not have had a material effect on our consolidated financial statements, but could result in significant unrealized foreign exchange gains or losses for any given period.

Item 4. Controls and Procedures.

Limitations on Effectiveness of Controls and Procedures

We maintain disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report, the effectiveness of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective at reasonable assurance level as of June 30, 2022 as a result of the material weaknesses described below.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. In connection with the preparation of our consolidated financial statements for the fiscal years ended December 31, 2020 and 2021, we identified material weaknesses in our internal control over financial reporting. The material weaknesses that were identified were related to the design of internal controls as follows: (1) the lack of a sufficient number of trained professionals with the expertise to design, implement and execute a formal risk assessment process and formal accounting policies, procedures and controls over accounting and financial reporting to ensure the timely recording, review, and reconciliation of financial transactions while maintaining a segregation of duties; (2) the lack of formal processes and controls specific to the identification and recording of expense transactions, including stock-based compensation, completely and accurately, and in the appropriate period; and (3) the lack of a sufficient number of trained professionals with the appropriate U.S. GAAP technical expertise to identify, evaluate and account for complex transactions and review valuation reports prepared by external specialists. As a result, we did not design and maintain formal accounting policies, processes and

65

controls related to complex transactions necessary for an effective financial reporting process. These deficiencies constitute material weaknesses in the design of our internal controls over financial reporting. As a result of the material weaknesses, we have relied, in part, on the assistance of outside advisors with expertise in these matters to assist us in the preparation of our consolidated financial statements and in our compliance with SEC reporting obligations and expect to continue to do so while we remediate these material weaknesses.

Management’s Remediation Efforts

As disclosed herein, we have identified and begun to implement several steps, as further described below, designed to remediate the material weaknesses described in this Item 4 and to enhance our overall control environment. Although we intend to complete the remediation process as promptly as possible, we cannot at this time estimate how long it will take to remediate these material weaknesses, and our remediation plan may not prove to be successful. We will not consider the material weaknesses remediated until our enhanced controls are operational for a sufficient period of time and tested, enabling management to conclude that the enhanced controls are operating effectively. As of June 30, 2022 the material weaknesses had not been remediated.

Our remediation plan to date includes, but is not limited to, the following measures:

•Formalizing our processes and internal control documentation and strengthening supervisory reviews by our financial management.

•Hiring additional qualified accounting personnel and engaging consultants to enable the implementation of internal control over financial reporting and segregating duties amongst accounting personnel.

•Implementing certain accounting systems to automate manual processes.

•We will also continue to engage third parties as required to assist with technical accounting, application of new accounting standards, tax matters, and valuations of our equity instruments, contingent consideration, notes receivable and acquired in-process research and development.

While the foregoing measures are intended to effectively remediate the material weaknesses described in this Item 4, it is possible that additional remediation steps will be necessary. As such, as we continue to evaluate and implement our plan to remediate the material weaknesses, our management may decide to take additional measures to address the material weaknesses or modify the remediation steps described above. Until these material weaknesses are remediated, we plan to continue to perform additional analyses and other procedures to help ensure that our consolidated financial statements are prepared in accordance with GAAP.

Changes in Internal Control over Financial Reporting

We are taking actions to remediate the material weaknesses relating to our internal controls over financial reporting, as described above. Except as discussed above, there were no changes in our internal control over financial reporting (as that term is defined in Rules 13a-15(d) or 15d-15(d) of the Exchange Act) that occurred during the quarter ended June 30, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

66

PART II- OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we have been and may again become involved in legal proceedings arising in the ordinary course of our business. Although the results of litigation and claims cannot be predicted with certainty, we do not believe we are party to any claim or litigation the outcome of which, if determined adversely to us, would individually or in the aggregate be reasonably expected to have a material adverse impact on our financial position, results of operations or cash flows. Regardless of the outcome, litigation can have an adverse effect on us because of defense and settlement costs, diversion of management resources and other factors.

Item lA. Risk Factors.

Investing in our common shares involves a high degree of risk. In addition to the other information set forth in this Quarterly Report and in other documents that we file with the SEC, you should carefully consider the factors described in the section titled "Risk Factors" in our Form 10-K. Other than as discussed below, there have been no material changes to the risk factors described in Part I, Item 1A of our Form 10-K. If any of the risk factors described in the Form 10-K actually materializes, our business, financial condition and results of operations could be materially adversely affected. In such an event, the market price of our common shares could decline and you may lose all or part of your investment. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

As a result of covenants related to our Loan Agreement with Hercules, our operating activities may be restricted and we may be required to repay the outstanding indebtedness in the event of a breach by us, or an event of default thereunder, which could have a materially adverse effect on our business.

As more fully described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity Risks – Indebtedness – Hercules Term Loan,” in August 2022, we entered into the Loan Agreement with Hercules, pursuant to which we have total borrowing capacity under several tranches of the 2022 Term Loan Facility of up to $175.0 million aggregate principal. The 2022 Term Loan Facility is secured by a lien on substantially all of our assets, including intellectual property, with certain limited exceptions set forth in the Loan Agreement. The Loan Agreement contains various covenants that may restrict our ability, among other things, to sell, transfer, lease or dispose of certain assets; make material changes to our business; incur indebtedness; encumber or permit liens on certain assets; make certain investments and acquisitions; make certain restricted payments, including paying dividends on, or repurchasing or making distributions with respect to, our common shares; and enter into certain transactions. Our business may be adversely affected by these restrictions on our ability to operate our business.

In addition, we are required under the Loan Agreement to comply with various covenants and default clauses that may restrict our ability to finance our operations, engage in business activities or expand or fully pursue our business strategies. A breach of any of these covenants or clauses could result in a default under the Lan Agreement, which could cause all of the outstanding indebtedness under the facility to become immediately due and payable.

We intend to satisfy our current and future debt service obligations with our existing cash, cash equivalents and available for sale securities, potential future product revenues and funds from external sources. However, we may not have sufficient funds or may be unable to arrange for additional financing on acceptable terms, or at all, to pay the amounts due under the 2022 Term Loan Facility.

Any breach by us, or any event of default under, our Loan Agreement could result in a material adverse effect on our business, financial condition and operating results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

As previously disclosed, in November 2018 and October 2020, ATAI Life Sciences AG issued an aggregate principal amount of €1.0 million of convertible notes in a notional amount of €1.00 each (the “2018 Notes”), each such 2018 Note convertible into one common share of ATAI Life Sciences AG at a conversion price of €17.00 per common share (an “ATAI AG Conversion Share”).

In connection with the 2018 Notes, on May 5, 2022, we entered into a Notes Conversion Agreement (the “Agreement”) with ATAI Life Sciences AG and a noteholder. Pursuant to the Agreement, the noteholder has converted 60,000 of its 2018 Notes into ATAI AG Conversion Shares in exchange for an aggregate payment of €1.0 million. In addition, pursuant to the Agreement, concurrent with the conversion of the 2018 Notes into ATAI AG Conversion Shares, the ATAI AG Conversion Shares has been exchanged into 960,000 common shares, par value €0.10 per share, of the Company through a transfer and sale arrangement.

No underwriter or underwriting discount was involved in the issuance of the common shares of the Company. The Agreement and the common shares of the Company issued in connection with the above transactions were offered and sold in transactions that were exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended.

Organization and Description of Business

1. Organization and Description of Business

ATAI Life Sciences N.V. (“atai”) is the parent company of ATAI Life Sciences AG and, along with its subsidiaries, is a clinical-stage biopharmaceutical company aiming to transform the treatment of mental health disorders. atai was founded in 2018 as a response to the significant unmet need and lack of innovation in the mental health treatment landscape. atai is dedicated to acquiring, incubating and efficiently developing innovative therapeutics to treat depression, anxiety, addiction, and other mental health disorders.

Since inception, atai has either created wholly owned subsidiaries or has made investments in certain controlled entities, including variable interest entities (“VIEs”) for which atai is the primary beneficiary under the VIE model (collectively, the “Company”). atai is headquartered in Berlin, Germany.

The Company has determined that it has one operating and reporting segment.

Corporate Reorganization and Initial Public Offering

atai was incorporated pursuant to the laws of the Netherlands as a Dutch private company with limited liability on September 10, 2020 for the purposes of becoming a holding company for ATAI Life Sciences AG and consummating the corporate reorganization described below. atai did not conduct any operations prior to the corporate reorganization other than activities incidental to its formation. ATAI Life Sciences AG was formed as a separate company on February 7, 2018.

In contemplation of the consummation of atai’s initial public offering (“IPO”) of common shares, atai undertook a corporate reorganization (the “Corporate Reorganization”). The Corporate Reorganization consisted of several steps as described below:

•Exchange of ATAI Life Sciences AG Securities for ATAI Life Sciences B.V. Common Shares and Share Split: In April 2021, the existing shareholders of ATAI Life Sciences AG each became a party to a separate notarial deed of issue under Dutch law and (i) subscribed for new common shares in ATAI Life Sciences B.V. and (ii) transferred their respective shares in ATAI Life Sciences AG, on a 1 to 10 basis (the “Exchange Ratio”), to ATAI Life Sciences B.V. as a contribution in kind on the common shares in ATAI Life Sciences B.V. As a result of the issuance of common shares in ATAI Life Sciences B.V. to the shareholders of ATAI Life Sciences AG and the contribution and transfer of their respective shares in ATAI Life Sciences AG to ATAI Life Sciences B.V., ATAI Life Sciences AG became a wholly owned subsidiary of ATAI Life Sciences B.V. No shareholder rights or preferences changed as a result of the share for share exchange. In connection with such exchange, the common share in ATAI Life Sciences B.V. held by Apeiron was cancelled. On June 7, 2021, shares of ATAI Life Sciences B.V. were split applying a ratio of 1.6 to one, and the nominal value of the shares was reduced to €0.10, pursuant to a shareholders’ resolution and amendment to the articles of association.

•Conversion of ATAI Life Sciences B.V. into ATAI Life Sciences N.V.: Immediately preceding the Company’s IPO, the legal form of ATAI Life Sciences B.V. was converted from a Dutch private company with limited liability to a Dutch public company, and the articles of association of ATAI Life Sciences N.V., became effective. Following the Corporate Reorganization, ATAI Life Sciences N.V. became the holding company of ATAI Life Sciences AG.

The Corporate Reorganization, as described above, is considered a continuation of ATAI Life Sciences AG resulting in no change in the carrying values of assets or liabilities. As a result, the financial statements for periods prior to the Corporate Reorganization are the financial statements of ATAI Life Sciences AG as the predecessor to atai for accounting and reporting purposes. All share, per-share and related information presented in these condensed consolidated financial statements and corresponding disclosure notes have been retrospectively adjusted, where applicable, to reflect the impact of the share exchange and share split resulting from the Corporate Reorganization. In connection with the Corporate Reorganization, outstanding share awards and option grants of ATAI Life Sciences AG were exchanged for share awards and option grants of ATAI Life Sciences B.V. with identical restrictions.

On June 22, 2021, atai closed the IPO of its common shares on the Nasdaq Stock Market ("Nasdaq"). As part of the IPO, the Company issued and sold 17,250,000 shares of its common shares, which included 2,250,000 shares sold pursuant to the exercise of the underwriters’ over-allotment option, at a public offering price of $15.00 per share. The Company received net proceeds of approximately $231.6 million from the IPO, after deducting underwriters’ discounts and commissions of $18.1 million and offering costs of $9.0 million.

Impact of COVID-19 Pandemic

The COVID-19 pandemic has continued to present global public health and economic challenges during the six months ended June 30, 2022. Although some research and development timelines have been impacted by delays related to the COVID-19 pandemic, the Company has not experienced material financial impacts on its business and operations as a result. The Company continues to monitor the impact of the COVID-19 pandemic on its employees and business and has undertaken business continuity measures to mitigate potential disruption to its operations.

The future impact of COVID-19 on the Company’s business and operations, including its research and development programs and related clinical trials, will largely depend on future developments, which are highly uncertain, such as the duration of the pandemic, the spread of the disease and variants thereof, the availability and effectiveness of vaccines and related roll-out efforts, breakthrough infections among the vaccinated, vaccine hesitancy, the implementation of vaccine mandates, travel restrictions, social distancing and related government actions around the world, business closures or business disruptions and the ultimate impact of COVID-19 on financial markets and the global economy.

Liquidity and Going Concern

The Company has incurred significant losses and negative cash flows from operations since its inception. As of June 30, 2022, the Company had cash and cash equivalents of $84.1 million, short-term securities of $228.4 million and its accumulated deficit was $431.3 million. The Company has historically financed its operations through the sale of equity securities, sale of convertible notes and revenue generated from licensing and collaboration arrangements. The Company has not generated any revenues to date from the sale of its product candidates and does not anticipate generating any revenues from the sale of its product candidates unless and until it successfully completes development and obtains regulatory approval to market its product candidates.

The Company currently expects that its existing cash and cash equivalents and short-term securities as of June 30, 2022 will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months from the date the condensed consolidated financial statements are issued.

Basis of Presentation and Summary of Significant Accounting Policies

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and follow the requirements of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and disclosures required by U.S. GAAP for complete financial statements as certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted.

The Company's condensed consolidated financial statements include the accounts of the Company and the accounts of the Company's subsidiaries. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). All intercompany transactions and accounts have been eliminated in consolidation.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the Company’s financial position, its results of operations and comprehensive loss, and its cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other future annual or interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC on March 30, 2022.

Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the condensed consolidated statements of operations for the three and six month periods ended June 30, 2021 to reclassify the foreign exchange loss. The foreign exchange loss for the three and six month periods ended June 30, 2021 was previously included in the other expense, net financial statement line.

Significant Accounting Policies

During the six months ended June 30, 2022, there were no significant changes to the Company’s significant accounting policies as described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2021 except as described below.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to the fair value of the Company’s investment in Intelgenx Technologies Corp. (“IntelGenx”), securities carried at fair value, contingent consideration liability—related parties, in-process research and development assets (“IPRD”), redeemable noncontrolling interests and noncontrolling interests

recognized in acquisitions, the valuations of common shares prior to IPO and share-based awards, and accruals for research and development costs.

The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. Actual results may differ from those estimates or assumptions.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. As of June 30, 2022 and December 31, 2021, cash and cash equivalents consisted of cash on deposit and cash held in high-yield savings accounts and money market funds.

Investment Securities Portfolio

The following table sets forth the fair value of atai's available-for-sale securities portfolio at the dates indicated:

	Fair Value
	June 30, 2022		December 31, 2021
Money Market Funds	$	38,878	$	—
U.S. Treasuries		3,478		—
Commercial Paper		114,880		—
Corporate Notes/Bonds		107,045		—
U.S. Government Agencies		2,951		—
	$	267,232	$	—

In January 2022, the Company invested in a certain investment portfolio, which is comprised of Money Market Funds, U.S. Treasury securities, Commercial Paper, Corporate Notes/Bonds, and U.S. government agencies securities. The Company classified securities in the investment portfolio as available-for-sale securities. Furthermore, the Company elected the fair value option for the available-for-sale securities in the investment portfolio (see Note 7). The decision to elect the fair value option, which is irrevocable once elected, is determined on an instrument-by-instrument basis and applied to an entire instrument. The net gains or losses, if any, on an investment for which the fair value option has been elected are recognized as a change in fair value of securities on the Consolidated Statements of Operations and the amortized cost of investments approximates their fair value.

Fair Value Measurements

Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s contingent consideration liability—related parties, derivative liability associated with the Perception convertible promissory notes, IntelGenx Initial Warrants and IntelGenx Additional Units Warrant, and warrant liability with Neuronasal Inc. are carried at fair value, determined according to Level 3 inputs in the fair value hierarchy described above (See Note 7). The IntelGenx common stock and securities carried at fair value are determined according to Level 2 inputs in the fair value hierarchy above. The carrying amount reflected in the accompanying consolidated balance sheets for cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values, due to their short-term nature.

The carrying amounts of the Company’s remaining outstanding convertible promissory notes—related parties issued in 2018 and 2020 (collectively, the “2018 Convertible Notes”) do not approximate fair value because the fair value is driven by the underlying value of the Company’s common shares into which the notes are to be converted. As of June 30, 2022, the carrying amount and fair value amount of the 2018 Convertible Notes was $0.6 million and $28.8 million, respectively. As of December 31, 2021, the carrying amount and fair value amount of the 2018 Convertible Notes was $0.8 million and $69.7 million, respectively. Subsequent to the IPO, several noteholders of the 2018 Convertible Notes elected to convert their promissory notes into the Company's common shares. See Note 10 for additional discussion.

Fair Value Option

As permitted under Accounting Standards Codification 825, Financial Instruments, or ASC 825, the Company has elected the fair value option to account for its investment in common shares of IntelGenx, which otherwise would be subject to ASC 323. In accordance with ASC 825, the Company records this investment at fair value under Other investments held at fair value in the Company's consolidated balance sheets and changes in fair value are recognized as a component of other income (expense), net in the consolidated statements of operations. The carrying value of the investment remained at zero as of June 30, 2022 and December 31, 2021, respectively.

Furthermore, as noted above the Company also elected the fair value option for its investment securities portfolio.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

As described in “Recently Adopted Accounting Pronouncements” below, the Company early adopted certain accounting standards, as the JOBS Act does not preclude an emerging growth company from adopting a new or revised accounting standard earlier than the time that such standard applies to private companies. The Company expects to use the extended transition period for any other new or revised accounting standards during the period in which it remains an emerging growth company.

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is a comprehensive new lease standard that amends various aspects of existing accounting guidance for leases. The core principle of Topic 842 requires lessees to recognize on the consolidated balance sheets a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases with lease terms greater than twelve months. The lease liability is measured at the present value of the unpaid lease payments and the right-of-use asset is derived from the calculation of the lease liability. Topic 842 also requires lessees to disclose key information about leasing arrangements. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. As a result of the Company having elected the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act, ASU 2016-02 is effective for the Company beginning after December 15, 2021.

The Company adopted the new standard on January 1, 2022 using the modified transition approach as of the effective date.

The new standard provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permitted it to not reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs. As a result, the Company has continued to account for existing leases - i.e. leases for which the commencement date is before January 1, 2022 - in accordance with Topic 840 throughout the entire lease term, including periods after the effective date, with the exception that the Company applied the new balance sheet recognition guidance for operating leases and applied Topic 842 for remeasurements and modifications after the Transition Date. The Company also elected the hindsight expedient in determining the lease term and assessing impairment of right-of-use assets when transitioning to ASC 842. As a result, the Company evaluated the lease term for its existing leases as of the transition date, January 1, 2022.

The most significant impact of the adoption of Topic 842 on the Company’s condensed consolidated financial statements was the recognition of a $0.2 million operating lease right-of-use asset, a $0.1 million current operating lease liability, and a $0.1 million long-term operating lease liability on the Company’s condensed consolidated balance sheet related to its existing facility operating lease. The Company did not have a deferred rent liability recorded in connection with its existing facility operating lease. There was no material impact to the Company’s condensed consolidated balance sheet, statement of operations, and no cumulative-effect adjustment to

accumulated deficit. The Company recorded an immaterial amount of general and administrative expense in its consolidated statement of operations related to lease expense, including short-term lease expense during the three and six months ended June 30, 2022.

Recently Issued Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses. This update requires immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred. The new model is applicable to most financial assets and certain other instruments that are not measured at fair value through net income. In November 2019, the FASB issued ASU 2019-10, which delays adoption for "smaller reporting companies" as defined under the rules promulgated under the Exchange Act. Although, as of December 31, 2021, the Company was no longer a smaller reporting company, the Company qualified as a smaller reporting company at the time of its initial public offering and, as such, in accordance with ASU 2019-10, the effective date for adoption by the Company will begin after December 31, 2022. The Company does not expect that the adoption of this new standard will have a material impact on its condensed consolidated financial statements and related disclosures.

Acquisitions

3. Acquisitions

2021 Acquisitions

PsyProtix, Inc.

In February 2021, the Company jointly formed PsyProtix with Chymia, LLC (“Chymia”). PsyProtix was created for the purpose of exploring and developing a metabolomics-based precision psychiatry approach, initially targeting the stratification and treatment of Treatment Resistant Depression (“TRD”) patients. In February 2021, pursuant to a Series A Preferred Stock Purchase Agreement (the “PsyProtix Purchase Agreement”), the Company acquired shares of PsyProtix’s Series A preferred stock in exchange for an initial payment of $0.1 million in cash. In addition, pursuant to the PsyProtix Purchase Agreement, the Company agreed to make aggregate payments to PsyProtix of up to $4.9 million upon the achievement of specified clinical milestones to complete the purchase of the shares and provide additional funding to PsyProtix. The PsyProtix Purchase Agreement resulted in the Company holding a 75.0% voting interest and Chymia holding a 25.0% voting interest in PsyProtix. In connection with the Company’s agreement for additional funding, PsyProtix issued the corresponding Series A preferred shares to the Company provided that the shares are held in an escrow account (the “PsyProtix Escrow Shares”). The PsyProtix Escrow Shares will be released, from time to time, to the Company upon PsyProtix achieving certain milestones as defined in the PsyProtix Purchase Agreement with cash payments to be made by the Company. In addition, the Company has the right, but not the obligation, to make payment for the certain PsyProtix Escrow Shares at any time, regardless of the achievement of any milestones. The PsyProtix Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, PsyProtix shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to PsyProtix and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares. In addition, prior to the occurrence of the earlier of a certain milestone event or reaching of the Company’s capital contribution threshold of $5.0 million, PsyProtix will issue additional shares of common stock to Chymia to maintain Chymia’s current ownership percentage. This anti-dilution right was concluded to be embedded in the common shares held by Chymia.

Immediately following the closing of the PsyProtix Purchase Agreement, PsyProtix loaned $0.1 million to Chymia in exchange for a duly executed promissory note (the “Chymia Note”). The Chymia Note shall accrue interest at a 5% rate per annum until payment in full. The aggregate principal amount of $0.1 million, together with all accrued and unpaid interest and all other amounts payable are due to be paid on the date that is the earlier of (i) five years from the promissory note agreement date or (ii) the occurrence of a liquidation event or a deemed liquidation event (as defined in the PsyProtix’s certificate of incorporation). As of June 30, 2022, the Chymia Note was $0.1 million and included as a component of long-term notes receivable—related parties on the consolidated balance sheets.

The PsyProtix Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of PsyProtix. The Company concluded that PsyProtix was not considered a business based on its assessment under ASC 805 and accounted for the Company’s acquisition in PsyProtix as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company did not recognize a gain or a loss in connection with the consolidation of PsyProtix as the fair value of the consideration paid of $0.1 million was equivalent to the fair value of the identifiable assets acquired of $0.1 million.

In October 2021, pursuant to the Board consent letter and the PsyProtix Purchase Agreement discussed above, the Company released a payment in the amount of $0.5 million upon the achievement of specified clinical milestones. Accordingly, 500,000 shares of Series A Preferred Stock were released from the escrow account to the Company. The Company's equity ownership interest in PsyProtix remained unchanged as the PsyProtix Escrow Shares were already deemed issued, outstanding and legally owned by atai.

Psyber, Inc.

Psyber is a globally based startup focused on the development of brain-computer interface-enabled digital therapeutics for treating mental health issues. Psyber was created as a joint venture between the Company and the founders of Psyber. In February 2021, pursuant to a Series A Preferred Stock Purchase Agreement (the “Psyber Purchase Agreement”), the Company acquired shares of Psyber’s Series A Preferred Stock in exchange for an initial payment of $0.2 million in cash. In addition, pursuant to the Psyber Purchase Agreement, the Company agreed to make aggregate payments to Psyber of up to $1.8 million upon the achievement of specified clinical milestones to complete the purchase of the shares and provide additional funding to Psyber. The Psyber Purchase Agreement resulted in the Company holding a 75.0% voting interest and the founders of Psyber jointly holding a 25.0% voting interest in Psyber. In connection with the Company’s agreement for additional funding, Psyber issued the corresponding Series A preferred shares to the Company provided that the shares are held in an escrow account (the “Psyber Escrow Shares”). The Psyber Escrow Shares will be released, from time to time, to the Company upon Psyber achieving certain milestones as defined in the Psyber Purchase Agreement with cash payments to be made by the Company. In addition, the Company has the right, but not the obligation, to make payment for the certain Psyber Escrow Shares at any time, regardless of the achievement of any milestones. The Psyber Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, Psyber shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to Psyber and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares. In addition, prior to the occurrence of the earlier of a certain milestone event or reaching of the Company’s capital contribution threshold of $2.0 million, Psyber will issue additional shares of common stock to the founders of Psyber to maintain the founders’ current ownership percentage. This anti-dilution right was concluded to be embedded in the common shares held by the founders of Psyber.

The Psyber Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of Psyber. The Company concluded that Psyber was not considered a business based on its assessment under ASC 805 and accounted for the Company’s acquisition in Psyber as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company recognized a de minimis gain for the three months ended March 31, 2021. The gain was calculated as the sum of the consideration paid of $0.2 million, less the fair value of identifiable net assets acquired of $0.2 million.

InnarisBio, Inc.

In February 2021, the Company jointly formed InnarisBio with UniQuest Pty Ltd (“UniQuest”) for the purpose of adding a solgel-based direct-to-brain intranasal drug delivery technology to the Company’s platform. In March 2021, pursuant to a Series A Preferred Stock Purchase Agreement (the “InnarisBio Purchase Agreement”), the Company acquired shares of InnarisBio’s Series A preferred stock in exchange for an initial payment of $1.1 million in cash. In addition, pursuant to the InnarisBio Purchase Agreement, the Company agreed to make aggregate payments to InnarisBio of up to $3.9 million upon the achievement of specified clinical milestones to complete the purchase of the shares and provide additional funding to InnarisBio. The InnarisBio Purchase Agreement resulted in the Company holding an 82.0% voting interest and UniQuest holding a 18.0% voting interest in InnarisBio. In connection with the Company’s agreement for additional funding, InnarisBio issued the corresponding shares of Series A preferred stock to the Company provided that the shares are held in an escrow account (the “InnarisBio Escrow Shares”). The InnarisBio Escrow Shares will be released, from time to time, to the Company upon InnarisBio achieving certain milestones as defined in the InnarisBio Purchase Agreement with cash payments to be made by the Company. In addition, the Company has the right, but not the obligation, to make payment for the InnarisBio Escrow Shares at any time, regardless of the achievement of any milestones. The InnarisBio Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, InnarisBio shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to InnarisBio and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares.

The InnarisBio Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of InnarisBio. The Company concluded that InnarisBio was not considered a business based on its assessment under ASC 805 and accounted for the Company’s acquisition in InnarisBio as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company recognized a de minimis loss on consolidation for the three months ended March 31, 2021. The loss was calculated as the sum of the consideration paid of $1.1 million, the fair value of the noncontrolling interest issued of $0.9 million, less the fair value of identifiable net assets acquired of $2.0 million. The fair value of the contingent milestone payments of $0.1 million was included in the total purchase consideration for the noncontrolling interest and recognized as a liability by InnarisBio at the date of acquisition. The fair value of the IPR&D acquired of $1.0 million was reflected as acquired in-process research and development expense on the consolidated statements of operations for the three months ended March 31, 2021 as it had no alternative future use at the time of the acquisition.

In November 2021, pursuant to the InnarisBio Purchase Agreement discussed above, the Company released a payment in the amount of $1.2 million upon the achievement of specified clinical milestones. Accordingly, 1,238,000 shares of Series A Preferred Stock were released from the escrow account to the Company. The Company's equity ownership interest in InnarisBio remained unchanged as the InnarisBio Escrow Shares were already deemed issued, outstanding and legally owned by the Company.

Neuronasal, Inc.

Neuronasal, Inc. (“Neuronasal”) is developing a novel intranasal formulation of N-acetylcysteine for acute mild traumatic brain injury. The Company first acquired investments in Neuronasal in December 2019 pursuant to a Preferred Stock Purchase Agreement (the “Neuronasal PSPA”). In December 2019, in connection with the original purchase of the preferred shares, Neuronasal and the Company entered into the Secondary Sale and Put Right Agreement (the “Neuronasal Secondary Sale Agreement”), whereby upon the achievement of certain contingent development milestones, existing common shareholders have the right to sell and the Company has the option but not the obligation to purchase additional shares of common stock at a price determined based on the fair market value per share on the date of exercise. These options that will allow the Company to purchase additional common shares are contingent upon the exercise of the options by Neuronasal’s common shareholders to sell shares to the Company. On March 10, 2021, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares for approximately $0.8 million based on the achievement of certain development milestones. Also, pursuant to the Neuronasal Secondary Sale Agreement, the Company purchased additional common shares for approximately $0.3 million. On May 17, 2021, pursuant to the Neuronasal PSPA the Company exercised its option to purchase additional shares of Series A preferred stock of Neuronasal for an aggregate cost of $1.0 million. The additional purchase on May 17, 2021 resulted in the Company obtaining an aggregate 56.5% ownership interest in Neuronasal, including the Company’s previously acquired investments in Neuronasal’s common and preferred stock, and provided the Company with control of Neuronasal’s board of directors and the unilateral rights to control all decisions related to the significant activities of Neuronasal. Prior to May 17, 2021, the Company accounted for its investments in Neuronasal’s common stock under the equity method and Neuronasal’s preferred stock under the measurement alternative (See Note 5). Following the closing of this acquisition on May 17, 2021, the results of Neuronasal have been consolidated in the Company’s consolidated financial statements.

TryptageniX, Inc.

TryptageniX, Inc. ("TryptageniX"), a Delaware corporation, was incorporated by CB Therapeutics, Inc. (“CBT”) on November 17, 2021, for the purpose of developing and commercializing Intellectual Property (“IP”) and to develop innovative biosynthetic methods to manufacture bioidentical, clinically relevant compounds, including psychoactive compounds which are highly difficult to produce sustainably through traditional methods. TryptageniX will generate New Chemical Entities (“NCE"). In December 2021, pursuant to the Stock Purchase Agreement ("TryptageniX-ATAI Stock Purchase Agreement"), atai acquired Class A Common Stock in exchange for $2.0 million and received a certificate representing additional Class A Common Stock to be held in escrow ("Escrow Shares") by TryptageniX to be released upon achievement of specified clinical milestones and corresponding milestone payments. The TryptageniX-ATAI Stock Purchase Agreement resulted in the Company holding a 65% equity ownership interest and CBT holding a 35% equity ownership interest in TryptageniX. The Escrow Shares will be released, from time to time, to the Company upon TryptageniX achieving certain milestones as defined in the TryptageniX Purchase Agreement with cash payments to be made by the Company. Notwithstanding anything to the contrary, atai shall be the owner of the Escrow Shares and has the right, but not the obligation, to make payment for the Escrow Shares at any time, regardless of the achievement of any milestones. The Escrow Shares have voting and all other rights until an event of default occurs where the Company fails to make a payment within 10 days following the written notice of the achievement of the relevant milestone. In the event of default, TryptageniX shall automatically repurchase a pro rata portion of the Escrow Shares from atai (“Repurchase Event”) for a purchase price per share equal to the par value of such Escrow Shares. Upon the Repurchase Event, the Escrow Shares are released from escrow to TryptageniX and thereafter cancelled. The Repurchase Event is the sole remedy upon atai’s failure to make the payment for the milestone shares.

On December 3, 2021, the Company made an additional payment of $1.0 million to CBT for the first installment of a $2.0 million exclusivity fee to become a party to the TryptageniX-ATAI Stock Purchase Agreement. The fee represents the exclusive right to the CBT technology and know-how defined in the TryptageniX Stockholders Agreement. The remaining installment of $1.0 million shall be paid no later than the second anniversary of the acquisition date, either in cash or in common shares of atai.

The TryptageniX-ATAI Stock Purchase Agreement provided the Company unilateral rights to control all decisions related to the significant activities of TryptageniX. The Company concluded that the acquired assets and activities of TryptageniX did not constitute a business based on its assessment under ASC 805 and accounted for the acquisition as an initial consolidation of a VIE that is not a business under ASC 810 (See Note 4). The assets acquired, liabilities assumed, and noncontrolling interest in the transaction were measured based on their fair values. The Company did not recognize a gain or a loss in connection with the consolidation of TryptageniX as the fair value of the consideration paid of $1.0 million was equivalent to the fair value of identifiable net assets acquired of $6.5 million, less the fair value of the noncontrolling interest issued of $3.9 million, fair value of the contingent consideration of $0.9 million, and fair value of liability for seller financing of $0.8 million. In December 2021, the Company elected to expense the entire fair value of the acquired IPR&D asset of $6.5 million as it had no alternative use at the acquisition date.

All acquisitions discussed above were considered as asset acquisitions and no goodwill was recognized upon consolidation.

Variable Interest Entities and a Voting Interest Entity

4. Variable Interest Entities

Consolidated VIEs

At each reporting period, the Company reassesses whether it remains the primary beneficiary for Variable Interest Entities (“VIEs”) consolidated under the VIE model.

The entities consolidated by the Company are comprised of wholly and partially owned entities for which the Company is the primary beneficiary under the VIE model as the Company has (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses that could potentially be significant to the VIE, or the right to receive benefits from the VIE that could potentially be significant to the VIE. The results of operations of the consolidated entities are included within the Company’s condensed consolidated financial statements from the date of acquisition to June 30, 2022.

As of June 30, 2022 and December 31, 2021, the Company has accounted for the following consolidated investments as VIEs, excluding the wholly owned subsidiaries:

Consolidated Entities	Relationship as of June 30, 2022	Relationship as of December 31, 2021	Date Control Obtained	Ownership % June 30, 2022	Ownership % December 31, 2021

As of June 30, 2022 and December 31, 2021, the assets of the consolidated VIEs can only be used to settle the obligations of the respective VIEs. The liabilities of the consolidated VIEs are obligations of the respective VIEs and their creditors have no recourse to the general credit or assets of atai.

EntheogeniX Biosciences, Inc.

In November 2019, the Company entered into a series of agreements with Cyclica Inc. ("Cyclica") to form EntheogeniX Biosciences, Inc. ("EntheogeniX"), a company dedicated to developing the next generation of innovative mental health drugs employing an AI-enabled computational biophysics platform designed to optimize and accelerate drug discovery. Based on the Company's assessment of the transaction at the time of acquisition, the Company concluded that EntheogeniX was not a business and accounted for the Company's investment as an initial consolidation of a VIE that is not a business under ASC 810.

In February 2022, pursuant to the business plan as contemplated in the Stockholders Agreement and Subscription for Shares pursuant to the Contribution and Subscription Agreement, atai purchased additional shares of Class A common stock for an aggregate purchase price of $1.0 million. As a result of anti-dilution protection available to Cyclica, the Company's ownership percentage in EntheogeniX did not

change due to the Class A common stock purchase. As of June 30, 2022 and December 31, 2021, the Company owned 80% of the outstanding common stock of EntheogeniX.

The purchase of additional Class A common stock was deemed to be a reconsideration event. The Company determined that EntheogeniX is still considered a VIE subsequent to the additional Class A common stock purchase as EntheogeniX does not have sufficient equity at risk to carry out its principal activities without additional subordinated financial support.

Redeemable Noncontrolling Interests

In connection with the consolidation of Kures, Inc. (“Kures”) the Company recognized the shares of Kures common stock and Series A-1 preferred stock held by the founders of Kures as redeemable noncontrolling interests as they contain embedded put options that are exercisable by the founders following a successful completion of a future event, which is not solely within the control of the Company.

In connection with the consolidation of DemeRx IB, the Company recognized common stock held by DemeRx as redeemable noncontrolling interests as they are redeemable upon the occurrence of events that are not solely within the control of the Company.

In connection with the consolidation of Neuronasal, the Company recognized the shares of Neuronasal common stock held by the founders of Neuronasal as redeemable noncontrolling interests as they contain embedded put options that are exercisable by the founders following a successful completion of a future event, which is not solely within the control of the Company.

The redeemable noncontrolling interests were initially measured at fair value upon issuance and are redeemable at fair value at the holder’s option upon the successful completion or occurrence of future events. As of June 30, 2022 and December 31, 2021, the Company did not adjust the carrying value of the redeemable noncontrolling interests based on their estimated redemption values since it was not probable

that the events that would allow the shares to become redeemable would occur. Subsequent adjustments to increase or decrease the carrying values of the redeemable noncontrolling interests to their estimated redemption values will be made if and when it becomes probable that such events will occur.

As of June 30, 2022 and December 31, 2021, the balance of redeemable noncontrolling interests in temporary equity on the consolidated balance sheets was zero. The amount of net loss attributable to redeemable noncontrolling interests of $0 million and $0 million are included in consolidated net loss on the face of the condensed consolidated statements of operations for the three months ended June 30, 2022 and 2021, respectively.

Non-consolidated VIEs

The Company evaluated the nature of its investments in Innoplexus AG (“Innoplexus”), DemeRx NB, Inc. (“DemeRx NB”) and IntelGenx and determined that the investments are VIEs as of the date of the Company’s initial investment through June 30, 2022. The Company is not the primary beneficiary as it did not have the power to direct the activities that most significantly impact the investments’ economic performance and therefore concluded that it did not have a controlling financial interest that would require consolidation as of June 30, 2022 and December 31, 2021.

The Company will reevaluate if the investments meet the definition of a VIE upon the occurrence of specific reconsideration events. The Company accounted for these investments under either the equity method, fair value option, or the measurement alternative included within ASC 321 (See Note 5). As of June 30, 2022, the Company’s maximum exposure for its non-consolidated VIEs was $9.2 million relating to the carrying values in other investments and other investments held at fair value and $7.0 million relating to the carrying value in long term notes receivable – related party. As of December 31, 2021, the Company’s maximum exposure for its non-consolidated VIEs was $11.6 million relating to the carrying values in its other investments and $3.8 million relating to the carrying value in short term notes receivable—related party.

Equity Method Investments

As of June 30, 2022 and December 31, 2021, the Company accounted for the following investments in the investee’s common stock under the equity method (amounts in thousands):

		As of June 30, 2022				As of December 31, 2021
	Date First	Common Stock		Carrying		Common Stock		Carrying
Investee	Acquired	Ownership %		Value		Ownership %		Value
Innoplexus A.G.	August 2018	35.0%		$	—	35.0%		$	—

GABA Therapeutics, Inc	November 2020	7.5%	(1)		—	7.5%	(1)		—
Total				$	1,162			$	16,131

(1)The Company is deemed to have significant influence over this entity through its total ownership interest in the entity’s equity, including the Company’s investment in the respective entity’s preferred stock, described below in Other Investments.

COMPASS Pathways plc

COMPASS Pathways plc ("COMPASS") is a mental health care company dedicated to pioneering the development of a new model of psilocybin therapy with its product COMP360. The Company first acquired investments in COMPASS in December 2018.

Equity Investment

Through a series of open market transactions between November 23, 2021 and December 7, 2021, the Company purchased an additional 1,490,111 of COMPASS ADSs at an aggregate purchase price of $47.4 million. The additional shares acquired resulted in an increase in

the Company’s ownership of COMPASS ADSs to 22.8%. The Company applied the cost accumulation model and recorded its investment at cost. At the date of the investment, a basis difference was identified as the cost basis of the Company’s investment in COMPASS exceeded the Company’s proportionate share of the underlying net assets in COMPASS. The Company concluded that the basis differences were primarily attributable to COMPASS’s IPR&D associated with COMP360, a psilocybin therapy, which COMPASS recently completed a Phase IIb clinical trial for. As the Company’s investment in COMPASS did not meet the definition of a business due to substantially all of the estimated fair value of the gross assets being concentrated in COMP360 and the associated IPR&D, the basis differences were attributable to the IPR&D with no alternative future use, and were immediately expensed at the time of the additional investment. As of June 30, 2022, the Company owned 22.5% of COMPASS ADS. Based on quoted market prices, the market value of the Company’s ownership in COMPASS was $103.5 million as of June 30, 2022.

Upon the completion of the COMPASS IPO and through June 30, 2022, the Company is deemed to continue to have significant influence over COMPASS primarily through its ownership interest in COMPASS’ equity and the Company's representation on COMPASS board of directors. Accordingly, the Company’s investment in COMPASS’ ADS was accounted for in accordance with the equity method through June 30, 2022.

During the three months ended June 30, 2022 and 2021, the Company recognized its proportionate share of COMPASS’ net loss of $4.7 million and $2.1 million, respectively, as losses from investments in equity method investees, net of tax on the condensed consolidated statements of operations. During the six months ended June 30, 2022 and 2021, the Company recognized its proportionate share of COMPASS' net loss of $9.5 million and $2.1 million, respectively, as losses from investments in equity method investees, net of tax on the condensed consolidated statements of operations.

Other Investments

The Company has accounted for its other investments that do not have a readily determinable fair value under the measurement alternative. As of June 30, 2022 and December 31, 2021, the carrying values of other investments, which consisted of investments in the investee’s preferred stock and common stock not in the scope of ASC 323 were as follows (in thousands):

	June 30,		December 31,
	2022		2021
GABA Therapeutics, Inc.	$	7,865	$	10,260
DemeRx NB, Inc.		1,024		1,024
Juvenescence Limited		344		344
Total	$	9,233	$	11,628

The Company’s investments in the preferred stock of Neuronasal (through May 2021), Innoplexus, GABA, and DemeRx NB are not considered as in-substance common stock due to the existence of substantial liquidation preferences and therefore did not have subordination characteristics that were substantially similar to the common stock. Although the Company’s investment in Juvenescence Limited (“Juvenescence”) is in common stock, it is not able to exercise significant influence over the operating and financial decisions of Juvenescence. The Company concluded that its ownership interests in above Other Investments do not have a readily determinable fair value and are accounted for under the measurement alternative. Under the measurement alternative, the Company measured its other investments at cost, less any impairment, plus or minus, if any, observable price changes in orderly transactions for an identical or similar investment of the same issuer.

During the three and six months ended June 30, 2022 and 2021 there were no observable changes in price recorded related to the Company’s Other Investments.

During the three and six months ended June 30, 2022 and 2021, the Company evaluated all of its other investments to determine if certain events or changes in circumstance during these time periods in 2022 and 2021 had a significant adverse effect on the fair value of any of its investments in non-consolidated entities. Based on this analysis, the Company did not note any impairment indicators associated with the Company’s Other Investments.

Innoplexus AG

Innoplexus is a technology company that provides “Data as a Service” and “Continuous Analytics as a Service” solutions that aims to help healthcare organizations leverage their technologies and expedite the drug development process across all stages—preclinical, clinical, regulatory and commercial. The Company first acquired investments in Innoplexus in August 2018.

As of December 31, 2020, the Company owned 35.0% of the common stock issued by Innoplexus. The Company has significant influence over Innoplexus through its noncontrolling representation on the investee’s supervisory board. Accordingly, the Company’s investment in Innoplexus’ common stock was accounted for in accordance with the equity method. The Company’s investment in Innoplexus’ preferred

stock did not meet the criteria for in-substance common stock. As such, the investment in Innoplexus’ preferred stock was accounted for under the measurement alternative as discussed below.

In February 2021, the Company entered into a Share Purchase and Assignment Agreement (the “Innoplexus SPA”) to sell its shares of common and preferred stock held in Innoplexus to a current investor of Innoplexus (the “Purchaser”) in exchange for an initial purchase price of approximately $2.4 million. In addition, the Company is entitled to receive contingent payments based on the occurrence of subsequent equity transactions or liquidity events at Innoplexus as determined under the Innoplexus SPA.

Pursuant to the Innoplexus SPA, the Purchaser is required to hold a minimum number of shares equivalent to the number of shares purchased from the Company through December 31, 2026. In the event that the Purchaser is in breach of this requirement, the purchaser is required to pay the Company an additional purchase price of approximately $9.6 million. The transaction was accounted for as a secured financing as it did not qualify for sale accounting under ASC Topic 860, Transfers and Servicing (ASC 860), due to the provision under the Innoplexus SPA which constrained the Purchaser from its right to pledge or exchange the underlying shares and provided more than a trivial benefit to the Company. The initial proceeds from the transaction are reflected as a secured borrowing liability of $2.2 million as of June 30, 2022, which is included in Other liabilities in the Company’s condensed consolidated balance sheet. The Company will continue to account for its investment in Innoplexus’ common stock under the equity method of accounting and its investment in Innoplexus’ preferred shares under the measurement alternative.

In addition, the Innoplexus SPA also provides the right for the Company to receive additional consideration with a maximum payment outcome of $22.3 million should the equity value of Innoplexus exceed certain thresholds upon the occurrence of certain events. The Company concluded that this feature met the definition of a derivative which required bifurcation. As the probability of the occurrence of certain events defined in the Innoplexus SPA was less than remote, the Company concluded that the fair value of the embedded derivative ascribed to this feature was de minimis as of June 30, 2022.

The carrying value of the Company’s investment in Innoplexus was zero as of June 30, 2022 and December 31, 2021.

GABA Therapeutics, Inc.

GABA is a California based biotechnology company focused on developing GRX-917 for anxiety, depression and a broad range of neurological disorders. The Company is deemed to have significant influence over GABA through its total ownership interest in GABA’s equity, including the Company’s investment in GABA’s preferred stock, and the Company’s noncontrolling representation on GABA’s board of directors.

Common Stock Investment

The Company’s investment in GABA’s common stock was accounted for in accordance with the equity method. The Company’s investment in GABA’s preferred stock did not meet the criteria for in-substance common stock. As such, the investment in GABA’s preferred stock is accounted for under the measurement alternative as discussed below.

The carrying value of the investment in GABA common stock was reduced to zero as of December 31, 2020 due to IPR&D charges with no alternative future use and remained zero as of June 30, 2022. Accordingly, GABA’s net losses attributable to the Company were determined based on the Company’s ownership percentage of preferred stock in GABA and recorded to the Company’s investments in GABA preferred stock discussed below. During the three months ended June 30, 2022 and 2021, the Company recognized its proportionate share of GABA’s net loss of $1.9 million and $0.4 million as losses from investments in equity method investees, net of tax on the consolidated statements of operations. During the six months ended June 30, 2022 and 2021, the Company recognized its proportionate share of GABA’s net loss of $2.7 million and $1.1 million, respectively, as losses from investments in equity method investees, net of tax on the consolidated statements of operations.

Preferred Stock Investment

In August 2019, GABA and the Company entered into the Preferred Stock Purchase Agreement (the “GABA PSPA”), whereby GABA issued shares of its Series A preferred stock to the Company at a price of approximately $5.5 million. At closing, the Company had an overall ownership interest of over 20% in GABA and a noncontrolling representation on the board. On May 15, 2021, GABA and the Company entered into an Amendment to Preferred Stock Purchase Agreement (the Amended GABA PSPA”) under which the GABA PSPA was amended. Pursuant to the Amended PSPA, GABA issued additional shares of its Series A preferred stock to the Company at a price of approximately $0.6 million. As of June 30, 2022 and December 31, 2021, the investment in GABA’s preferred stock was recorded in Other Investments on the consolidated balance sheets under the measurement alternative under ASC 321.

Pursuant to the GABA PSPA, the Company is obligated to purchase additional shares of Series A preferred stock for up to $10.0 million with the same price per share as its initial investment, upon the achievement of specified contingent clinical development milestones. On April 13, 2021, pursuant to the GABA PSPA, the Company purchased additional shares of Series A preferred stock of GABA, for an aggregate cost of $5.0 million based on the achievement of certain development milestones. On May 21, 2021, the Company exercised its

option to purchase additional shares of Series A preferred stock prior to the achievement of certain development milestone for an aggregate cost of $5.0 million. The completion of the Series A Preferred stock purchase in May 2021 was deemed to be a reconsideration event at which point GABA was no longer deemed a VIE as GABA now had sufficient equity at risk to finance its activities through the initial development period without additional subordinated financial support. Entities that do not qualify as a VIE are assessed for consolidation under the voting interest model (“VOE model”). Under the VOE model, the Company consolidates the entity if it determines that it, directly or indirectly, has greater than 50% of the voting shares and that other equity holders do not have substantive voting, participating or liquidation rights. While the Company holds greater than 50% of the outstanding equity interest of GABA, the Company does not have the power to control the entity. Concurrent with the exercise of the option, the Company executed a side letter with the other equity holders of GABA agreeing to forego the rights to additional seats on the board of directors, resulting in the Company lacking the ability to control the investee. The Company concluded that it does not have a controlling financial interest that would require consolidation under the VOE model and accounted for the investments in GABA preferred stock under the measurement alternative per ASC 323.

As of December 31, 2021, the Company completed the purchase of the additional shares of Series A preferred stock for $10.0 million pursuant to the GABA PSPA. Pursuant to the Amended GABA PSPA, the Company is obligated to purchase additional shares of Series A preferred stock from GABA for up to $1.5 million with the same price per share as its initial investment upon the achievement of specified contingent clinical development milestones.

In accordance with the Amended GABA PSPA, the Company also has the option but not the obligation to purchase the aforementioned additional shares of Series A preferred stock at any time prior to the achievement of any milestone at the same price per share as its initial investment. In August 2019, pursuant to the Right of First Refusal and Co-Sale Agreement, the Company has the option but not the obligation to purchase additional shares of common stock for up to $2.0 million from the existing common shareholders.

In November 2020 the Company exercised its option to purchase additional shares of common stock of GABA at a price of approximately $1.8 million pursuant to an Omnibus Amendment Agreement under which the Right of First Refusal and Co-Sale Agreement was amended.

Neuronasal, Inc.

Neuronasal is developing a novel intranasal formulation of N-acetylcysteine (“NAC”) for acute mild traumatic brain injury.

Common Stock Investment

In October 2020, upon the achievement of certain development milestones, the Company made a cash contribution of $0.3 million in exchange for 9.8% of the outstanding common stock of Neuronasal. The carrying value of the investment in Neuronasal common stock was reduced to zero as of December 31, 2020 due to IPR&D charges with no alternative future use. Accordingly, Neuronasal’s net losses attributable to the Company was determined based on the Company’s ownership percentage of preferred stock in Neuronasal and recorded to the Company’s investments in Neuronasal preferred stock discussed below.

On March 10, 2021, upon the achievement of certain development milestones, the Company made another cash contribution of $0.5 million in exchange for 10.8% of the outstanding common stock of Neuronasal. The Company recorded its investment in Neuronasal common stock at the carrying cost basis of $0.5 million. At the date of the investment, a basis difference was identified as the cost basis of the Company’s investment in Neuronasal exceeded the Company’s proportionate share of the underlying net assets in Neuronasal. The Company concluded that the basis differences were primarily attributable to Neuronasal’s IPR&D associated with Neuronasal’s novel intranasal formulation of NAC. As the Company’s investments in Neuronasal did not meet the definition of a business due to substantially all of the estimated fair value of the gross assets being concentrated in NAC, the basis differences were attributable to the IPR&D with no alternative future use, and were immediately expensed on the dates of investments. The Company’s proportionate share of the basis difference exceeded its carrying value of the equity method investment in Neuronasal and as a result, the March 2021 equity investment balance of $0.5 million was reduced to zero. For the three months ended March 31, 2021, the Company recognized losses from investments in equity method investees, net of tax of $0.5 million in association with the basis difference charge in the Company’s consolidated statements of operations.

The Company was deemed to have significant influence over Neuronasal through its total ownership interest in Neuronasal’s equity through the acquisition date of May 17, 2021 (see Note 3), including the Company’s investment in Neuronasal’s preferred stock, and the Company’s noncontrolling representation on Neuronasal’s board of directors. Accordingly, the Company’s investment in Neuronasal’s common stock was accounted for in accordance with the equity method. Immediately prior to the acquisition, the Company recognized its proportionate share of Neuronasal’s year to date net loss of $1.0 million, as losses from investments in equity method investees, net of tax on the consolidated statements of operations.

The Company’s investment in Neuronasal’s preferred stock did not meet the criteria for in-substance common stock. As such, the investment in Neuronasal’s preferred stock was accounted for under the measurement alternative as discussed below.

Preferred Stock Investment

In December 2019, Neuronasal and the Company entered into the Neuronasal PSPA and the Neuronasal Secondary Sale Agreement, whereby Neuronasal issued shares of its Series A preferred stock to the Company at a price of approximately $0.5 million. At closing, the Company had a less than 20% of ownership interest in Neuronasal and a noncontrolling representation on the board. In October 2020, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares at a price of approximately $0.8 million. The investment in Neuronasal preferred shares was recorded in Other Investments on the consolidated balance sheets under the measurement alternative under ASC 321 as of June 30, 2022 and December 31, 2021.

In October 2020, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares at a price of approximately $0.8 million upon the achievement of a specified contingent clinical development milestone. On March 10, 2021, pursuant to the Neuronasal PSPA, the Company purchased additional Series A preferred shares for approximately $0.8 million based on the achievement of certain development milestones.

On May 17, 2021, pursuant to the Neuronasal PSPA and the Neuronasal Secondary Sale Agreement, the Company, at its sole option, purchased additional shares of Series A preferred stock of Neuronasal for an aggregate cost of $1.0 million. Upon the closing of the purchase on May 17, 2021, the Company obtained a controlling financial interest in Neuronasal. The Company derecognized its other investments in Neuronasal and began to consolidate the operations of Neuronasal into its financial statements. See Note 3, “Acquisitions” for further discussion.

DemeRx NB

In December 2019, the Company jointly formed DemeRx NB with DemeRx. DemeRx and DemeRx NB entered into a Contribution Agreement whereby DemeRx assigned all of its rights, title, and interests in and to all of its assets relating to DMX-1002, Noribogaine, in exchange for shares of common stock of DemeRx NB. DemeRx NB will use the contributed intellectual property to develop Noribogaine. Noribogaine is an active metabolite of ibogaine designed to have a longer plasma half-life and potentially reduced hallucinogenic effects compared to ibogaine.

In connection with the Contribution Agreement, the parties entered into a Series A Preferred Stock Purchase Agreement (the “DemeRx NB PSPA”) pursuant to which the Company purchased shares of Series A preferred stock of DemeRx NB at a purchase price of $1.0 million. At closing, the Company had less than 20% of ownership interest in DemeRx NB and a noncontrolling representation on DemeRx NB's board of directors. The investment in DemeRx NB was recorded in Other Investments on the condensed consolidated balance sheets under the measurement alternative under ASC 321.

Pursuant to the DemeRx NB PSPA, the Company also has the option but not the obligation to purchase additional shares of DemeRX NB's Series A preferred stock at a purchase price of up to an aggregate of $19.0 million with the same price per share as its initial investment in December 2019. As of June 30, 2022, the Company has not exercised its option to purchase any shares of Series A preferred stock of DemeRx NB.

Other Investments Held at Fair Value

IntelGenx Technologies Corp.

IntelGenx is a novel drug delivery company focused on the development and manufacturing of novel oral thin film products for the pharmaceutical market. In March 2021, IntelGenx and the Company entered into the Strategic Development Agreement and Purchaser Rights Agreement (“PPA”). On May 14, 2021, IntelGenx and the Company executed a Securities Purchase Agreement (the “IntelGenx SPA”) after obtaining IntelGenx shareholder approval, whereby IntelGenx issued shares of its common stock and warrants to the Company at a price of approximately $12.3 million. Each warrant (the “Initial Warrants”) entitles the Company to purchase one share at a price of $0.35 per share for a period of three years from the closing of the initial investment in March 2021. Pursuant to the IntelGenx SPA, the Company has the right to purchase (in cash, or in certain circumstances, the Company’s equity) additional units for a period of three years from the closing of the initial investment (the “Additional Unit Warrants”). Each Additional Unit Warrant will be comprised of (i) one share of common stock and (ii) one half of one warrant (the “Additional Warrants”). The price for the Additional Unit Warrants will be (i) until the date which is 12 months following the closing and the purchase does not result in the Company owning more than 74,600,000 common shares of IntelGenx, $0.331 (subject to certain exceptions), and (ii) until the date which is 12 months following the closing and the purchase results in the Company owning more than 74,600,000 common shares of IntelGenx or following the date which is 12 months following the closing regardless of the number of shares held by the Company, the lower of (A) a 20% premium to the volume weighted average price of the common share for the thirty trading days immediately preceding the news release of the additional closing, and (B) $0.50 if purchased in the second year following closing or $0.75, if purchased in the third year following closing. Each Additional Warrant will entitle the Company, for a period of three years from the date of issuance, to purchase one share at the lesser of either (i) a 20% premium to the price of the corresponding additional share, or (ii) the price per share under which shares of IntelGenx are issued under convertible instruments that were outstanding on February 16, 2021, provided that the Company may not exercise Additional Warrants to purchase more than the lesser of (x) 44,000,000 common shares of IntelGenx, and (y) the number of common shares issued by IntelGenx

under outstanding convertibles held by other investors as of February 16, 2021. Following the initial closing, the Company held a 25% voting interest in IntelGenx. Pursuant to the PPA, the Company is entitled to designate a number of directors to the IntelGenx’s board of directors in the same proportion as the shares of common stock held by the Company to the outstanding of IntelGenx common shares.

Pursuant to the Strategic Development Agreement, the Company engages IntelGenx to conduct research and development projects (“Development Project”) using IntelGenx’s proprietary oral thin film technology. Under the terms of the Strategic Development Agreement, the Company can select four (4) program products. As of the effective date of the Strategic Development Agreement, the Company nominated two (2) program products - DMT and Salvinorin A. 20% of any funds that IntelGenx received or will receive through the Company’s equity investment under the IntelGenx SPA will be available to be credited towards research and development services that IntelGenx conducts for the Company under the Development Projects. For the three and six months ended June 30, 2022, the Company recorded an immaterial amount of research & development expense in its condensed consolidated statement of operations in relation to the IntelGenx projects described above. No material research and development services were performed during the three and six months ended June 30, 2021.

The Company has significant influence over IntelGenx through ownership interest in IntelGenx’s equity and the Company’s noncontrolling representation on IntelGenx’s board of directors. The Company qualified for and elected to account for its investment in the IntelGenx common stock under the fair value option. The Company believes that the fair value option better reflects the underlying economics of the IntelGenx common stock investment. The Initial Warrants and Additional Units Warrant, (collectively the “Warrants”) are accounted for at fair value under ASC 321 and recorded in Other investments held at fair value on the consolidated balance sheets. The Company applied a calibrated model and determined that the initial aggregate fair value is equal to the transaction price and recorded the common shares at $3.0 million, the Initial Warrants at $1.2 million and the Additional Unit Warrants at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the consolidated statements of operations. The Company recognizes subsequent changes in fair value of the common shares and the Warrants as a component of other income (expense), net in the consolidated statement of operations. The carrying amount of the investment was reduced to zero as of December 31, 2021, during the three and six months ended June 30, 2022, the Company recognized a $0 mark-to-market (“MTM”) gain/loss in the consolidated statements of operations. The carrying value of the investment remained at zero as of June 30, 2022 and December 31, 2021, respectively.

Long Term Notes Receivable – Related Party

Loan to IntelGenx Corp.

On March 8, 2021, the Company and IntelGenx entered into a loan agreement under which the Company provided a loan to IntelGenx for an aggregate principal amount of $2.0 million (the “March Term Loan”). Pursuant to the loan agreement, IntelGenx may, by written notice, request an advance up to an additional $0.5 million as an additional term loan if no event of default has occurred as defined in the loan agreement. On May 11, 2021, the Company paid an additional advance of $0.5 million as an additional term loan (the “May Term Loan”, and together with the March Term Loan the “Term Loans”). The Term Loans were originally due to mature 120 days following the special shareholder meeting of IntelGenx Tech Corp. to approve an additional investment in IntelGenx Tech Corp. by the Company ("Maturity Date"). On May 14, 2021, the Company amended the loan agreement under which the Maturity Date will be the first business day following the first closing of a subscription for additional units if the proceeds from such subscription amount to at least $3.0 million. The loan bears an annualized interest rate of 8% and such interest is accrued daily. The principal amount of the Term Loans plus any accrued interest shall become due and payable on the Maturity Date. On September 14, 2021, the Company entered into an amended and restated loan agreement, which among other things, increased the principal amount of loans available to IntelGenx by $6.0 million, up to a total of $8.5 million. The additional loan amount of $6.0 million are funded via two separate tranches of $3.0 million each in the beginning of 2022 and 2023 respectively, subject to certain conditions. In addition, the amendment further extended the Maturity Date to January 5, 2024. The first tranche was funded in January 2022.

Pursuant to the terms of the Term Loans, upon the occurrence of an event of default, the Company may accelerate the Term Loans and declare the principal and any accrued and unpaid interests of the Term Loans to be immediately due and payable. In addition, IntelGenx may prepay the Term Loans in whole or in part at any time without premium or penalty. Any prepayment of the principal shall be accompanied by a payment of interest accrued to date thereon. The Company concluded that these embedded features do not meet the criteria to be bifurcated and separately accounted for as derivatives.

The Company recorded the Term Loans at cost which included the principal balance of the note and accrued interest in Long term notes receivables – related parties on its consolidated balance sheets. As of June 30, 2022, the Term Loans have an outstanding balance of $5.9 million. For the three and six months ended June 30, 2022, the Company recognized interest income of $0.1 million and $0.2 million associated with the Term Loans. For the three and six months ended June 30, 2021, the Company recognized an immaterial amount of interest income associated with the Term Loans. The Company assesses the Term Loans for impairment and records an impairment loss when information becomes available that indicates it is probable that the Term Loans have been impaired and the amount of the loss can be reasonably estimated. As of June 30, 2022, no impairment indicators were present.

Investment in DemeRx Promissory Note—Related Party

On January 3, 2020, DemeRx IB loaned to DemeRx $1.0 million pursuant to the terms of a Promissory Note (the "DemeRx Note"). Pursuant to the terms of the DemeRx Note, the aggregate principal amount of $1.0 million together with all accrued and unpaid interest and any other amounts payable are due to be paid on the date that is the earlier of (i) 5 years from the initial closing and (ii) the closing of an initial public offering or a deemed liquidation event of DemeRx IB (the “DemeRx Maturity Date”). Pursuant to the terms of the DemeRx Note, DemeRx may, in its sole discretion pay any amount due under the DemeRx Note, in cash or through cancellation shares of common stock of DemeRx IB, par value $0.0001 per share, of the fair market value of such shares.

The Company recorded the DemeRx Note at cost which included the principal balance of the DemeRx Note and accrued interest, net of any payments received, on its condensed consolidated balance sheets. As of June 30, 2022, and December 31, 2021, respectively, the DemeRx Note had an outstanding balance of $1.1 million and $1.1 million, respectively. For the three and six months ended June 30, 2021, the Company recognized an immaterial amount of interest income associated with the DemeRx Note as a component of Other Income in the consolidated statements of operations. For the three and six months ended June 30, 2022, the Company did not earn any interest income associated with the DemeRx Note.

Investment Securities Portfolio - Fair Value Option

The Company elected the fair value option for the securities in the investment portfolio. The fair value is based on quoted market prices, when available. When a quoted market price is not readily available, the Company uses the market price from its last sale of similar assets.

The cash and cash equivalents held by the Company are categorized as Level 1 investments as quoted market prices are readily available for these investments. All other investments in the investment portfolio are categorized as Level 2 investments as inputs utilized to fair value these securities are either directly or indirectly observable, such as the market price from the last sale of similar assets.

The Company purchases investment grade marketable debt securities which are rated by nationally recognized statistical credit rating organizations in accordance with its investment policy. This policy is designed to minimize the Company's exposure to credit losses and to ensure that the adequate liquidity is maintained at all times to meet anticipated cash flow needs.

The unrealized gains and losses on the available-for-sale securities, represented by change in the fair value of the investment portfolio, is reported in earnings. Since the investment in the available-for-sale securities are already measured at fair value, no separate credit losses would be recorded in the financials.

Contingent Consideration Liability—Related Parties—Perception, InnarisBio, and TryptageniX

The contingent consideration liability—related parties in the table above relates to milestone and royalty payments in connection with the acquisition of Perception Neuroscience Holdings, Inc. (“Perception”), InnarisBio and TryptageniX. The fair value of the contingent consideration liability—related parties was determined based on significant inputs not observable in the market, which represent Level 3 measurements within the fair value hierarchy. The fair value of the contingent milestone and royalty liabilities was estimated based on the discounted cash flow valuation technique. The technique considered the following unobservable inputs:

• the probability and timing of achieving the specified milestones and royalties as of each valuation date,

• the probability of executing the license agreement,

• the expected first year of revenue, and

• market-based discount rates

The fair value of the contingent milestone and royalty liabilities for InnarisBio was estimated to be $0.1 million and $0.1 million as of June 30, 2022 and December 31, 2021, respectively.

The fair value of the Perception contingent milestone and royalty liabilities could change in future periods depending on prospects for the outcome of R-Ketamine milestone meetings with the FDA or other regulatory authorities, and whether the Company realizes a significant increase or decrease in sales upon commercialization. The most significant assumptions in the discounted cash flow valuation technique that impacts the fair value of the milestone contingent consideration are the projected milestone timing and the probability of the milestone being met. Further, significant assumptions in the discounted cash flow that impacts the fair value of the royalty contingent consideration are the projected revenue over ten years, the timing of royalties on commercial revenue, and the probability of success rate for a commercial R-Ketamine product. The valuations as of June 30, 2022 and December 31, 2021, respectively, used inputs that were unobservable inputs with the most significant being the discount rates for royalties on projected commercial revenue and clinical milestones and probability of success estimates over the following ten years, which represent Level 3 measurements within the fair value hierarchy.

The fair value of the contingent milestone and royalty liabilities for Perception was estimated to be $1.4 million and $1.5 million as of June 30, 2022 and December 31, 2021, respectively.

The fair value of the Perception contingent consideration liability - related parties was calculated using the following significant unobservable inputs:

		June 30, 2022	December 31, 2021
Valuation Technique	Significant Unobservable Inputs	Input Range	Input Range
Discounted cash flow	Milestone contingent consideration:
	Discount rate	15.4%	11.4%
	Probability of the milestone	51.9%	51.9%
Discounted cash flow    with SBM	Royalty contingent consideration:
	Discount rate for royalties	22.5% - 24.0%	19.2% - 20.1%
	Discount rate for royalties on milestones	14.2% - 15.6%	10.9% - 11.8%
	Probability of success rate	26.5% - 51.9%	26.5% to 100.0%

The fair value of the contingent liability for TryptageniX was estimated to be $0.8 million and $0.9 million as of June 30, 2022, and December 31, 2021, respectively. The contingent liability is comprised of R&D milestone success fee payments and royalties payments. The fair value of the success fee liability was estimated based on the scenario-based method within the income approach. The fair value of the contingent liability for TryptageniX was determined based on significant unobservable inputs, including the discount rate, estimated

probabilities of success, and timing of achieving certain clinical milestones. The fair value of the royalties liability was determined to be de minimis as the products are in the early stages of development. The Company will continue to assess the appropriateness of the fair value of the contingent liability as the products continue through development.

Warrant Liability

The warrant liability in the table above relates to issued and outstanding warrants to purchase shares of Neuronasal’s common stock acquired in connection with the acquisition of Neuronasal. The warrants were classified within other liabilities in the accompanying condensed consolidated balance sheet as the underlying common stock was determined to be contingently, but not currently, redeemable. The warrant liability was recorded at fair value utilizing the Black-Scholes option pricing model. As summarized below, certain key inputs in connection with the Black-Scholes option pricing model represent Level 3 measurements within the fair value hierarchy. The Black Scholes option pricing model is based on the estimated market value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected dividends, and expected volatility of the price of the underlying common stock. The Company adjusted the carrying value of the warrant to its estimated fair value at each reporting date, with any related increase or decrease in the fair value recorded as a component of other income (expense), net in the condensed consolidated statement of operations.

The fair value of the warrant liability was estimated to be $0.3 million and $0.3 million as of June 30, 2022 and December 31, 2021, respectively.

The following table summarizes significant unobservable inputs that are included in the valuation of the warrant lability as of June 30, 2022:

IntelGenx Common Stock, Initial Warrants and Additional Units Warrant

The Company’s investment in IntelGenx consists of Common Shares, Initial Warrants and Additional Units Warrant (collectively the “Warrants”). The Company determined that the Warrants do not meet the definition of a derivative instrument under ASC 815. The Company has classified the Common Shares as Level 2 assets and the Warrants as Level 3 assets in the fair value hierarchy. The Company determined that the initial aggregate fair value was equal to the transaction price and recorded the Common Shares at $3.0 million, the Initial Warrants at $1.2 million and the Additional Units Warrant at $8.2 million on a relative fair value basis resulting in no initial gain or loss recognized in the consolidated statements of operations. The Warrants are measured at fair value on a quarterly basis and any changes in the fair value will be recorded as a component of other income (expense), net in the condensed consolidated statement of operations.

The fair value of Common Shares is estimated by applying a discount for lack of marketability (“DLOM”) of 5.0% as of December 31, 2021 and June 30, 2022. The Company estimated a DLOM in connection with the valuation of the Common Shares at initial recognition and as of June 30, 2022 to reflect the restrictions associated with the Common Shares. As of June 30, 2022 the only restriction that remains is the unregistered nature of the Common Shares. The fair value of Common Shares, which is included in Other investments held at fair value in the consolidated balance sheet, was zero as of June 30, 2022 and December 31, 2021, respectively.

The Initial Warrant asset was recorded at fair value utilizing the Black-Scholes option pricing model. The Black Scholes option pricing model is based on the estimated market value of the underlying common stock at the valuation measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected dividends, and expected volatility of the price of the underlying common stock. The expected volatility is based on a peer group volatility which is a Level 3 input within the fair value hierarchy. The fair value of the Initial Warrants, which is included in Other investments held at fair value in the condensed consolidated balance sheet, was zero as of June 30, 2022 and December 31, 2021, respectively.

The following table summarizes significant unobservable inputs that are included in the valuation of the Initial Warrants as of June 30, 2022:

	June 30, 2022
Value of Underlying	$	0.16
Expected Volatility		115	%

The following table summarizes significant unobservable inputs that are included in the valuation of the Initial Warrants as of December 31, 2021:

	December 31, 2021
Value of Underlying	$	0.34
Expected Volatility		105	%

The fair value of the Additional Units is estimated using a Binomial Lattice in a risk-neutral framework (a special case of the Income Approach). Specifically, the future stock price of the IntelGenx is modeled assuming a Geometric Brownian Motion in a risk-neutral framework. For each modeled future price, the Additional Unit is calculated based on the contractual terms (incorporating any optimal early exercise), and then discounted at the term-matched risk-free rate. Finally, the value of the Additional Units is calculated as the probability-weighted present value over all future modeled payoffs. The fair value of the Additional Units, which is included in Other investments held at fair value in the condensed consolidated balance sheet, was zero as of June 30, 2022 and December 31, 2021, respectively.

The following table summarizes significant unobservable inputs that are included in the valuation of the Additional Units Warrant as of June 30, 2022:

	June 30, 2022

2018 Convertible Promissory Notes—Related Parties

Convertible promissory notes—related parties, net of discounts and deferred issuance costs, consisted of the following (in thousands):

Convertible notes issued in November 2018	$	48	$	125

During November 2018, the Company executed a terms and conditions agreement (the “Convertible Note Agreement”) under which it was authorized to issue up to €1.0 million or $1.2 million in convertible promissory notes to investors. An investor would become a party to the Convertible Note Agreement and would be issued a convertible promissory note by executing and delivering a subscription form. In November 2018, certain investors subscribed to the Convertible Note Agreement and the Company issued convertible promissory notes in the aggregate principal amount of €0.2 million or $0.2 million.

In October 2020, certain investors subscribed to the Convertible Note Agreement and the Company issued the remainder of the 2018 Convertible Notes in the aggregate principal amount of €0.8 million or $1.0 million (collectively, the “2018 Convertible Notes”). The total aggregate principal amount of the 2018 Convertible Notes is $1.2 million as of December 31, 2020. The 2018 Convertible Notes are non-interest-bearing, unsecured and are due and payable on September 30, 2025, unless previously redeemed, converted, purchased or cancelled (the “Maturity Date”). Each 2018 Convertible Note has a notional value of €1 and is convertible into one share of ATAI Life

Sciences AG upon the payment of €17.00. Conversion rights may be exercised by a noteholder at any time prior to maturity, except during certain periods subsequent to the consummation of the IPO. The 2018 Convertible Notes may be declared for early redemption by the noteholders upon occurrence of specified events of default, including payment default, insolvency and a material adverse change in the Company’s business, operations or financial or other condition. Upon early redemption, the conversion right with respect to the 2018 Convertible Notes may no longer be exercised.

In connection with the Convertible Note Agreement, the Company issued convertible notes in the principal amounts of €0.1 million or $0.1 million to the founders of Perception, who are also related parties of the Company in November 2018 (See Note 17). Perception is a biotech firm acquired by the Company on November 5, 2018. Upon the purchase of certain assets of Perception in November 2018, Perception was deemed to have been a VIE, of which the Company is the primary beneficiary (See Note 4).

In addition, in connection with the Convertible Note Agreement, the Company issued convertible notes in the principal amounts of €0.5 million or $0.6 million to Apeiron, the family office of the Company’s co-founder, and €0.3 million or $0.4 million to one other shareholder of the Company and the founder of COMPASS in October 2020.

The Company concluded that both the embedded conversion feature, which is exercisable by the investor at any time during the maturity, and the contingent put option, which would trigger upon the occurrence of an event of default of the 2018 Convertible Notes, do not meet the criteria to be bifurcated and separately accounted for as derivatives and the notes were recorded net of discount and issuance costs, or a reduction to the carrying value of the notes issued in November 2018, with a corresponding adjustment to additional paid in capital. The discount is being amortized using the effective interest method over the period from the respective date of issuance to the Maturity Date.

The Company determined that the October 2020 notes were issued in exchange for services previously provided by the Company’s founders and other shareholders and were fully vested and non-forfeitable upon issuance. These instruments were therefore considered share based compensation awards to non-employees, and the instruments were initially measured and recorded at their grant date fair value based on a Black-Scholes option- pricing model.

The fair value of the October 2020 notes exceeded the principal amount that will be due at maturity. Therefore, at initial recognition, the October 2020 notes were accounted for as convertible debt issued at a substantial premium, such that the face value of the October 2020 Notes are recorded as a liability and the premium was recorded as paid-in capital.

Conversion of 2018 Convertible Promissory Notes - Related Parties

As described in Note 1, the Company undertook a corporate reorganization. Upon the Corporate Reorganization, ATAI Life Sciences N.V became the sole shareholder of ATAI Life Sciences AG. In connection with the Corporate Reorganization, all former shareholders of ATAI Life Sciences AG contributed their shares of ATAI Life Sciences AG to ATAI Life Sciences N.V. and received sixteen shares in ATAI Life Sciences N.V. for every one share of ATAI Life Sciences AG. In 2021, several noteholders elected to convert their convertible promissory notes into shares of ATAI Life Sciences N.V. These investors paid €17.00 per share for an aggregate amount of €5.8 million or $6.9 million in order to convert their convertible promissory notes into ATAI Life Sciences AG common shares, which was in accordance with the original terms of the 2018 Convertible Note Agreements.

In May 2022, an additional noteholder elected to convert some of their convertible promissory notes into shares of ATAI Life Sciences N.V. The investor paid €17.00 per share for the aggregate amount of €1.0 million or $1.1 million in order to convert its convertible promissory notes into ATAI Life Sciences AG common shares, which was in accordance with the original terms of the 2018 Convertible Note Agreements.

The Company accounted for the conversion of the 2018 Convertible Notes as a conversion such that carrying values of these notes were derecognized with an offset to common stock at par of ATAI Life Sciences AG and the excess of the carrying values of these notes over the common stock at par of ATAI Life Sciences AG was recorded as additional paid-in capital. Concurrently, with the conversion of the 2018 Convertible Notes into ATAI Life Sciences AG shares, the shares of ATAI Life Sciences AG that were issued to the noteholders were exchanged for shares of ATAI Life Sciences N.V. through a transfer and sale arrangement. As ATAI Life Sciences AG continued to remain a wholly owned subsidiary of ATAI Life Sciences N.V., the transaction was accounted for as an equity transaction that resulted in no gain or loss recognition.

Perception Convertible Promissory Notes

On March 16, 2020, Perception entered into a convertible promissory note agreement with the Company and other investors, including related parties, which provided for the issuance of convertible notes of $3.9 million (the “Perception Note Purchase Agreement”).

The notes bear interest at an annual rate of 5% and are due and payable on June 30, 2022, unless earlier converted (the “Perception March 2020 Notes”).

On December 1, 2020, Perception entered into an additional convertible promissory note agreement (the “Perception December 2020 Convertible Note Agreement”) with the Company and other investors, including related parties, which provided for the issuance of convertible notes of up to $12.0 million. Pursuant to the Perception December 2020 Convertible Note Agreement, the convertible notes are issued in two tranches: (i) up to $7.0 million under the first tranche funding (the “First Tranche Funding”), with $6.2 million and $0.8 million issued in December 2020 and January 2021, respectively, and (ii) up to an additional $5.0 million under the second tranche funding (the “Second Tranche Funding”), was issued in May 2021.

Under the Second Tranche Funding, Perception issued $4.2 million to the Company, $0.2 million to Apeiron, and $0.3 million to Sonia Weiss Pick and Family, and $0.4 million to other investors.

The notes bear interest at an annual rate of 5% and are due and payable on February 28, 2022, unless earlier converted (the “Perception December 2020 Notes” and together with the Perception March 2020 Notes, the “Perception Convertible Notes”).

In the event of a qualified sale of preferred stock resulting in gross proceeds to Perception of at least $5.0 million, all the principal and accrued and unpaid interest under the Perception Convertible Notes will automatically convert, into the same equity securities issued by Perception at a 25% discount from the lowest price of the security issued. In the event that Perception receives upfront proceeds of $5.0 million or more in a licensing transaction, all the principal and accrued and unpaid interest under the Perception convertible notes will automatically convert, into shares of Series A Preferred Stock of Perception at a price per share of $0.75 for the Perception March 2020 Notes and 75% of the fair market value of the Series A Preferred Stock of Perception for the Perception December 2020 Notes. Upon a change in control of Perception, all the principal and accrued and unpaid interest under the Perception Convertible Notes will automatically convert into shares of Series A Preferred Stock of Perception at a price per share of $0.75. The Perception Convertible Notes issued to the Company represent intercompany debt and are eliminated upon consolidation.

The Perception March 2020 Notes contained an embedded conversion features in the event of a qualified financing whereas the Perception December 2020 Notes contained both embedded conversion features in the event of a qualified financing and upon the occurrence of a licensing transaction. The Company concluded that both the embedded conversion features met the definition of embedded derivatives that were required to be bifurcated and accounted for as a separate unit of accounting.

As of December 31, 2020, the Company recorded the fair value of the derivative liabilities of $0.4 million as a liability with the offset being recorded as a debt discount on the issuance dates of the Perception Convertible Notes.

Both the liability and the offsetting debt discount are presented together in convertible promissory notes and derivative liability on the consolidated balance sheets. The resulting debt discount is being amortized to interest expense using the effective interest method over the terms of the Perception Convertible Notes. This interest expense is recorded in other income (expense), net in the consolidated statements of operations. The derivative liabilities are subsequently remeasured to fair value at each reporting date with changes in fair value recognized as a component of other income (expense), net in the consolidated statements of operations.

Upon issuance of the notes under the Second Tranche Funding, the Company recorded the fair value of the derivative liabilities of $0.3 million as a liability with an offset being recorded as a debt discount.

On June 10, 2021, Perception received proceeds of $20.0 million pursuant to the license and collaboration arrangement between Perception and Otsuka Pharmaceutical Co., LTD (“Otsuka”) (See Note 16). Upon receipt of the proceeds, the Perception Convertible Notes automatically converted into 6,456,595 shares of Series A preferred stock of Perception pursuant to their original terms. The Company, Sonia Weiss Pick and Family, Apeiron, and other investors received 5,403,791 shares, 440,415 shares, 27,809 shares and 584,580 shares of Perception Series A preferred stock, respectively, upon conversion of the Perception Convertible Notes. The amounts associated with the shares of Perception Series A preferred stock issued to the Company represent intercompany transactions and are eliminated upon consolidation.

Upon receipt of the proceeds described above, the Company remeasured the derivative liability immediately prior to the conversion of the Perception Notes and recorded a net gain of $41,000 resulting from the change in fair value of the derivative liability in June 2021. The conversion of the Perception December 2020 Notes was accounted for as an extinguishment as the notes were converted pursuant to an embedded conversion feature upon a licensing transaction, which was determined to be a redemption feature. Accordingly, the Company recorded a loss on extinguishment of notes of $0.5 million in the consolidated statements of operations in June 2021. The loss on extinguishment of notes represents the difference between (i) carrying value including derivative liability of the Perception December 2020 Notes of $2.2 million and (ii) the fair value of Perception Series A preferred stock into which the notes converted of $2.7 million.

The conversion of the Perception March 2020 Notes was accounted for as a conversion as the notes converted pursuant to a conversion feature. Accordingly, the Company derecognized the carrying amount of the Perception March 2020 notes issued to Sonia Weiss and Family and other investors in the aggregate amount of $0.6 million with an offset to Series A preferred stock, and no gain or loss was

recognized. The shares issued upon conversion of the Perception March 2020 and December 2020 Notes issued to the Company represent an intercompany transaction and, therefore, eliminate in consolidation.

The Company recognized interest expense of $0.1 million, including amortization of debt discount of $93,000 during the three months ended June 30, 2021. The Company recognized interest expense of $0.2 million, including amortization of debt discount of $0.2 million during the six months ended June 30, 2021. As of June 30, 2021, there was no unamortized debt discount due to the conversion of the Perception Convertible Notes into Series A convertible preferred stock of Perception on June 10, 2021. The debt issuance costs associated with the Perception Convertible Notes were not material.

Atai Life Sciences 2021 Incentive Award Plan

Effective April 23, 2021, the Company adopted and the atai shareholders approved the 2021 Incentive Award Plan (“2021 Incentive Plan”). The 2021 Incentive Plan is administered by the Company’s supervisory board. The plan is intended to encourage ownership of shares by employees, directors, and certain consultants to the Company in order to attract and retain such individuals, to induce them to work for the benefit of the Company or of an affiliate and to provide additional incentive for them to promote the success of the Company.

Stock Options

The stock options outstanding noted below consist primarily of both service and performance-based options to purchase Common Stock. These stock options have a five-year contractual term. These awards are subject to the risk of forfeiture until vested by virtue of continued employment or service to the Company.

The following is a summary of stock option activity from December 31, 2021 to June 30, 2022:

	Number of Options				Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value

(2)The 21,035,201 outstanding unvested stock options balance includes (a) 16,203,479 that will continue to vest over a one to four-year service period, (b) 2,908,034 that will continue to vest over a three to four-year service period and upon the satisfaction of specified performance-based vesting conditions, (c) 200,000 stock options that will continue to vest over a two-year service period and upon the satisfaction of specified market-based conditions tied to price of the Company's publicly traded shares, (d) 754,910 stock options that will vest immediately upon the satisfaction of specified performance-based vesting conditions, which were not considered probable of achievement as of June 30, 2022, (e) 584,778 stock options that will continue to vest over a three-year service period and upon the satisfaction of specified performance-based vesting conditions, which were not considered probable of achievement as of June 30, 2022, and (f) 384,000 stock options that will vest on the one-year anniversary of the date of grant.

The weighted-average grant-date fair value of options granted during the six months ended June 30, 2022 was $3.48.

The Company estimated the fair value of each stock option using the Black-Scholes option-pricing model on the date of grant. During the six months ended June 30, 2022, the assumptions used in the Black-Scholes option pricing model were as follows:

	June 30,
	2022		2021
Weighted average expected term in years		5.93		3.64
Weighted average expected stock price volatility	70.5%		81.2%
Risk-free interest rate	1.46% - 3.03%		(0.76%) - 1.27%
Expected dividend yield	0%		0%

For the three months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $8.1 million and $20.6 million, respectively. For the six months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $16.7 million and $20.6 million, respectively.

As of June 30, 2022, total unrecognized compensation cost related to the unvested stock-based awards was $87.5 million, which is expected to be recognized over a weighted average period of 2.11 years.

Atai Life Sciences Hurdle Share Option Plan

On August 21, 2020, the Partnership (as defined below) approved and implemented an employee stock option plan for selected executives, employees, and consultants of the Partnership (the so-called Hurdle Share Options Program or “HSOP Plan”), which became effective on January 2, 2021, the date the first grants under the HSOP Plan were made (the “HSOP Options”). This plan is primarily aimed at German-based executives, employees, and consultants of the Company (collectively, the “HSOP Participants”). The purpose of the HSOP Plan is to permit these individuals to indirectly participate in the appreciation in value of the Company through a German law private partnership,

ATAI Life Sciences HSOP GbR (the “Partnership”). The HSOP Plan was established under the Partnership Agreement of the Partnership. The HSOP Plan requires the exercise price to be equal to the fair value of the shares on the date of grant.

The Partnership acquired 7,281,376 shares of atai common stock (“HSOP Shares”) pursuant to the HSOP Plan. HSOP Options that are canceled or forfeited without having been fully exercised will be available for future awards. As of June 30, 2022, 132,752 HSOP Options were available for future grants under the HSOP Plan.

The HSOP Plan mimics the economics of a typical stock option plan, however, with the HSOP Shares to which the HSOP Options refer already being issued to the Partnership. Each HSOP Option contains both service and performance-based vesting conditions, including a liquidity-based condition, and gives the holder the option to request the distribution of HSOP Shares under its vested HSOP Options. The nominal amount paid at the grant date is refundable if the HSOP Options do not vest or are forfeited. Otherwise, the nominal amount is refundable until the later of the occurrence of a Liquidity Event (as defined in the “HSOP Plan”) or the exercise date.

The HSOP Shares issued under the HSOP Plan to the Partnership are indirectly owned by HSOP Participants (being the holders of HSOP Options) via their interest in the Partnership. The grantee is required to pay a nominal value (€0.06 per share) for the shares upon grant (“Nominal Upfront Payment”). Accordingly, the HSOP Shares issued to the Partnership and allocated to the HSOP Options holders are not considered outstanding for accounting purposes. Therefore, the Company accounted for the Nominal Upfront Payment as an in-substance early exercise provision under ASC 718 as the nominal amount is deducted from the exercise price upon exercise. As of June 30, 2022, the remaining $0.5 million Nominal Upfront Payment was recorded as an Other liability on the consolidated balance sheets.

HSOP Options

The HSOP Options outstanding noted below consist of service and performance-based options to request the distribution of HSOP Shares. These HSOP Options have a fifteen-year contractual term. These HSOP Options vest over a three to four-year service period, only if and when a “Liquidity Event” (as defined in the Partnership agreement) occurs within fifteen years of the date of grant. If a Change in Control (as defined in the Partnership agreement) or in the event the holder’s service with the Partnership is terminated due to his death or disability by June 30, 2021 or December 31, 2021, an additional 25% or 12.5%, respectively, HSOP Options will accelerate and vest upon the occurrence of the transaction. These awards are subject to the risk of forfeiture until vested by virtue of continued employment or service to the Company.

The liquidity-based performance condition contingent upon the achievement of a Liquidity Event was satisfied in June of 2021, therefore, the Company began recognizing expense for all associated options that were previously deemed improbable of vesting.

The following is a summary of stock option activity for from December 31, 2021 to June 30, 2022:

	Number of Options		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value

Options exercisable as of June 30, 2022		5,537,474	$	6.64		13.51

For the three months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $1.2 million and $16.7 million, respectively. For the six months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $2.5 million and $16.7 million, respectively.

As of June 30, 2022, total unrecognized compensation cost related to the unvested stock-based awards was $5.6 million which is expected to be recognized over a weighted average period of 0.8 years.

Subsidiary Equity Incentive Plans

Certain controlled subsidiaries of the Company adopted their own equity incentive plans (each, an “EIP”). Each EIP is generally structured so that the applicable subsidiary, and its affiliates’ employees, directors, officers and consultants are eligible to receive non-qualified and incentive stock options and restricted stock unit awards under their respective EIP. Standard option grants have time-based vesting requirements, generally vesting over a period of four years with a contractual term of ten years. Such time-based stock options use the Black-Scholes option pricing model to determine grant date fair value. Certain awards issued to employees partially vest on date of grant,

then over a three-year service period and upon the satisfaction of specified performance-based vesting conditions, which are not considered probable of achievement as of June 30, 2022.

For the three months ended June 30, 2022 and 2021, the Company recorded share-based compensation expense of $0.2 million and $0.2 million, respectively, in relation to subsidiary EIPs. For the six months ended June 30, 2022 and 2021, the Company recorded share-based compensation expense of $0.4 million and $0.4 million, respectively, in relation to subsidiary EIPs. As of June 30, 2022, there was $8.2 million of total unrecognized stock-based compensation expense related to unvested EIP awards to employees and non-employee directors expected to be recognized over a weighted-average period of approximately 3.0 years.

Stock-Based Compensation

Stock-based compensation expense is allocated to either Research and development or general and administrative expense on the condensed consolidated statements of operations based on the cost center to which the option holder belongs.

Income Taxes

13. Income Taxes

The Company records its quarterly income tax expense by utilizing an estimated annual effective tax rate applied to its period to date earnings as adjusted for any discrete items arising during the quarter. The tax effect for discrete items are recorded in the period in which they occur. The Company recorded $51,000 and $58,000 income tax expense for the three months ended June 30, 2022 and 2021 respectively. The Company recorded $92,000 and $64,000 income tax expense for the six months ended June 30, 2022 and 2021, respectively. The income tax expense during these periods was primarily driven by current tax on earnings of subsidiaries in Australia, the United States, and the United Kingdom. The primary difference between the effective tax rate and the statutory tax rate is a result of certain income tax deductions available in the United States that are permanent in nature. The Company continues to maintain a full

valuation allowance against its deferred tax assets with the exception of certain deferred tax assets relating to certain subsidiaries in Australia, the United States and the United Kingdom.

14. Net Income (Loss) Per Share

Basic and diluted net loss per share attributable to atai stockholders were calculated as follows (in thousands, except share and per share data):

	Three Months Ended June 30,						Six Months Ended June 30,
	2022			2021			2022			2021
Numerator:
Net loss	$	(37,509	)	$	(53,373	)	$	(75,067	)	$	(49,329	)
Net loss attributable to redeemable    noncontrolling interests and noncontrolling    interests		(891	)		(4,912	)		(1,580	)		(1,556	)

Net loss per share attributable to ATAI Life    Sciences N.V. shareholders - basic and diluted	$	(0.24	)	$	(0.37	)	$	(0.48	)	$	(0.38	)

HSOP Shares issued to the Partnership and allocated to the HSOP Participants are not considered outstanding for accounting purposes and not included in the calculation of basic weighted average common shares outstanding in the table above because the HSOP Participants have a forfeitable right to distributions until the HSOP Options vest and are exercised, at which time the right becomes nonforfeitable.

The following also represents the maximum amount of outstanding shares of potentially dilutive securities that were excluded from the computation of diluted net income (loss) per share attributable to common shareholders for the periods presented because including them would have been antidilutive:

Potentially dilutive securities to the Company’s common shares:

	As of June 30,
	2022		2021
Options to purchase common stock		34,410,771		23,797,993
HSOP options to purchase common stock		7,046,496		7,281,376
2018 Convertible Promissory Notes - Related Parties (Note 10)		9,561,824		16,000,000
		51,019,091		47,079,369

The remaining 2018 Convertible Notes would be issuable upon the exercise of conversion rights of convertible note holders for 597,614 shares of common stock of ATAI Life Sciences AG, respectively. Upon conversion, it is expected that the remaining 2018 Convertible Notes would be exchanged on a one-for-sixteen basis for shares of ATAI Life Sciences N.V. which is reflected in the table above.

Commitments and Contingencies

15. Commitments and Contingencies

Research and Development Agreements

The Company may enter into contracts in the ordinary course of business with clinical research organizations for clinical trials, with contract manufacturing organizations for clinical supplies and with other vendors for preclinical studies, supplies and other services and products for operating purposes.

Leases

As of June 30, 2022, the Company has entered into a five year lease arrangement that has not yet commenced. The Company expects the lease to commence by the end of 2022. This lease will require lease payments over the term of approximately $1.8 million.

Indemnification

In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to vendors, lessors, business partners, board members, officers and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company, negligence or willful misconduct of the Company, violations of law by the Company, or intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. No demands have been made upon the Company to provide indemnification under such agreements, and thus, there are no claims that the Company is aware of that could have a material effect on the Company’s consolidated financial statements.

The Company also maintains director and officer insurance, which may cover certain liabilities arising from its obligation to indemnify the Company’s directors. To date, the Company has not incurred any material costs and has not accrued any liabilities in the consolidated financial statements as a result of these provisions.

Contingencies

From time to time, the Company may become involved in legal proceedings arising in the ordinary course of business. The Company is unable to predict the outcome of these matters or the ultimate legal and financial liability, and at this time cannot reasonably estimate the possible loss or range of loss and accordingly has not accrued a related liability. At each reporting date, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company accrues a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, the Company does not record a liability, but instead discloses the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can be made. Legal fees are expensed as incurred. The Company currently believes that the outcome of these legal proceedings, either individually or in the aggregate, will not have a material effect on its consolidated financial position, results of operations or cash flows.

License Agreements

16. License Agreements

Otsuka License and Collaboration Agreement

On March 11, 2021, Perception entered into a license and collaboration agreement (the “Otsuka Agreement”) with Otsuka under which Perception granted exclusive rights to Otsuka to develop and commercialize products containing arketamine, known as PCN-101, in Japan for the treatment of any depression, including treatment-resistant depression, or major depressive disorder or any of their related symptoms or conditions. Under the terms of the Otsuka Agreement, Otsuka received an exclusive right to develop and commercialize products containing PCN-101 in Japan at its own cost and expense. Perception retained all rights to PCN-101 outside of Japan.

Otsuka owed Perception an upfront, non-refundable payment of $20.0 million as of the execution of the Otsuka Agreement. Perception is also entitled to receive aggregate payments of up to $35.0 million if certain development and regulatory milestones are achieved for the current or a new intravenous formulation of a product and up to $66.0 million in commercial milestones upon the achievement of certain commercial sales thresholds. Otsuka is obligated to pay Perception a tiered, double-digit royalty on net sales of products containing PCN-101 in Japan, subject to reduction in certain circumstances.

The Otsuka Agreement will expire upon the fulfillment of Otsuka’s royalty obligations on a product-by-product basis. Otsuka shall have the right to terminate this agreement in its entirety for convenience at any time (a) on ninety (90) days’ prior written notice to Perception if such notice is given before the first regulatory approval of the first licensed product in the Otsuka territory, or (b) on one hundred and eighty (180) days’ prior written notice to Perception if such notice is given on or after the first regulatory approval of the first licensed product in the Otsuka territory. The Otsuka Agreement may be terminated in its entirety at any time during the term upon written notice by either party if the other party is in material breach of its obligations and has not cured such breach within thirty (30) days in the case of a payment breach, or within ninety (90) days in the case of all other breaches.

The Company first assessed the Otsuka Agreement under ASC 808 to determine whether the Otsuka Agreement or units of accounts within the Otsuka Agreement represent a collaborative arrangement based on the risks and rewards and activities of the parties.

The Company concluded that Otsuka is a customer in the context of the Otsuka Agreement and the units of account are within the scope of ASC 606. The Company determined that the combined promise of the exclusive license to PCN-101 and non-exclusive license to conduct clinical trials in Asia are a single performance obligation. The Company determined that the option rights for CMC study data, additional research services and development supply do not represent material rights to Otsuka as these options were issued at standalone selling prices. As such, they are not performance obligations at the outset of the arrangement.

Based on this assessment, the Company concluded three performance obligations existed at the outset of the Otsuka Agreement: (i) the exclusive license to PCN-101 and exclusive license to conduct clinical trials in Japan, (ii) Global Requested Ongoing Clinical Studies (as

defined in the Otsuka Agreement) and (iii) Global Ongoing Clinical Studies (as defined in the Otsuka Agreement). The Company determined that the upfront payment of $20.0 million constitutes the transaction price at the outset of the Otsuka Agreement. Future potential milestone payments were fully constrained as the risk of significant revenue reversal related to these amounts has not yet been resolved. The achievement of the future potential milestones is not within the Company’s control and is subject to certain research and development success or regulatory approvals and therefore carry significant uncertainty. The Company will reevaluate the likelihood of achieving future milestones at the end of each reporting period. As all performance obligations will have been satisfied in advance of the achievement of the milestone events, if the risk of significant revenue reversal is resolved, any future milestone revenue from the arrangement will be added to the transaction price (and thereby recognized as revenue) in the period the risk is resolved.

For the three and six months ended June 30, 2022, no additional milestones were achieved under the Otsuka Agreement and the Company did not recognize any revenue associated with the Otsuka Agreement based on performance completed during the period. The remaining deferred revenue balance related to the Otsuka Agreement is not material as of June 30, 2022. Perception satisfied the performance obligation related to the license upon delivery of the license and recognized the amount of $19.7 million allocated to the license as license revenue during the six months ended June 30, 2021. Additionally, the Company recognized license revenues of $0.2 million related to certain research and development services during the three and six months ended June 30, 2022. The Company did not recognize material license revenue during the three and six months ended June 30, 2021.

National University Corporation Chiba University License Agreement

In August 2017, Perception entered into a license agreement (the “CHIBA License”), with the National University Corporation Chiba University (“CHIBA”), relating to Perception’s drug discovery and development initiatives. Under the CHIBA License, Perception has been granted a worldwide exclusive license under certain patents and know-how of CHIBA to research, develop, manufacture, use and commercialize therapeutic products.

During the three and six months ended June 30, 2022 and 2021, respectively, the Company made no material payments pursuant to the CHIBA License.

Allergan License Agreement

In February 2020, Recognify entered into an amended and restated license agreement (the “Allergan License Agreement”), with Allergan Sales, LLC (“Allergan”), under which Allergan granted Recognify an exclusive (non-exclusive as to know-how), sublicensable and worldwide license under certain patent rights and know-how controlled by Allergan to develop, manufacture and commercialize certain products for use in all fields including the treatment of certain diseases and conditions of the central nervous system.

During the three and six months ended June 30, 2022 and 2021, respectively, Recognify made no material payments pursuant to the Allergan License Agreement.

Columbia Stock Purchase and License Agreement

In June 2020, Kures entered into a license agreement with Trustees of Columbia University (“Columbia”), pursuant to which, Kures obtained an exclusive license under certain patents and technical information to discover, develop, manufacture, use and commercialize such patents or other products in all uses and applications (“Columbia IP”). In addition, in consideration for the rights to the Columbia IP, Kures entered into a Stock Purchase Agreement (the “SPA”) with Columbia in contemplation of the license agreement. Pursuant to the SPA, Kures issued to Columbia certain shares of the Kures’ capital stock, representing 5.0% of Kures common stock on a fully diluted basis. Furthermore, the SPA provided that from time to time, Kures shall issue to Columbia additional shares of Kures’ common stock, at a per share price equal to the then fair market value of each such share, which price shall be deemed to have been paid in partial consideration for the execution, delivery and performance by Columbia of the License Agreement, such that the common stock held by Columbia shall equal to 5.0% of the common stock on a fully diluted basis, at all times up to and through the achievement of certain funding threshold.

During the three months ended June 30, 2022, Kures issued shares of Series A-2 Preferred Stock to certain investors upon the achievement of Series A-2 milestone events. Accordingly, the Company issued certain anti-dilution common stock to Columbia worth $0.3 million. The Company expensed the cost incurred for acquiring license as research & development expense at inception. Since, the additional anti-dilution shares were issued as partial consideration towards the same license arrangement, the cost of such additional share was also expensed as research & development expense during the three and six months ended June 30, 2022.

During the three and six months ended 2021, Kures made no material payments in connection with the Columbia agreement.

Accelerate License Agreement

On April 27, 2021, Psyber entered into a license arrangement with Accelerate Technologies Pte. Ltd. (“Accelerate”), whereby Accelerate grants Psyber non-exclusive rights to license and use the technology to commercialize of Psyber’s BCI-enabled companion digital

therapeutics in United States of America, Singapore, Member Countries of the European Union, Canada, Australia and New Zealand as a potential treatment for mental health and behavior change, such as substance use disorders including opioid use disorder, mood and anxiety disorders including post-traumatic stress disorder, and treatment-resistant depression.

During the three and six months ended June 30, 2022 and 2021, respectively, Psyber made no material payments pursuant to the Accelerate License agreement.

Dalriada License Agreement

On December 10, 2021, Invyxis, Inc. ("Invyxis"), a wholly owned subsidiary of the Company, entered into an exclusive services and license agreement (the "Invyxis ESLA") with Dalriada Drug Discovery Inc. ("Dalriada"). Under the Invyxis ESLA, Dalriada is to exclusively collaborate with Invyxis to develop products, services and processes with the specific purpose of generating products consisting of new chemical entities. Invyxis will pay Dalriada up to $12.8 million in service fees for research and support services. In addition, Invyxis will pay Dalriada success milestone payments and low single digit royalty payments based on net product sales. Invyxis has the right, but not the obligation, to settle future royalty payments based on net product sales with the Company's common stock. Invyxis and Dalriada will determine the equity settlement based on a price per share determined by both parties.

In January 2022, in accordance with the Invyxis ESLA, Invyxis paid an upfront deposit of $1.1 million, which was capitalized as prepaid research and development expense. The Company will expense the upfront deposit as the services are performed as a component of research and development expense in the consolidated statements of operations. During the three and six months ended June 30, 2022, the Company recorded $1.4 million and $1.8 million as research and development expense, respectively. During the three and six months ended June 30, 2022, Invyxis made no other service fee payments to Dalriada.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and follow the requirements of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and disclosures required by U.S. GAAP for complete financial statements as certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted.

The Company's condensed consolidated financial statements include the accounts of the Company and the accounts of the Company's subsidiaries. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). All intercompany transactions and accounts have been eliminated in consolidation.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the Company’s financial position, its results of operations and comprehensive loss, and its cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other future annual or interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC on March 30, 2022.

Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the condensed consolidated statements of operations for the three and six month periods ended June 30, 2021 to reclassify the foreign exchange loss. The foreign exchange loss for the three and six month periods ended June 30, 2021 was previously included in the other expense, net financial statement line.

Significant Accounting Policies

Significant Accounting Policies

During the six months ended June 30, 2022, there were no significant changes to the Company’s significant accounting policies as described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2021 except as described below.

Use of Estimates

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to the fair value of the Company’s investment in Intelgenx Technologies Corp. (“IntelGenx”), securities carried at fair value, contingent consideration liability—related parties, in-process research and development assets (“IPRD”), redeemable noncontrolling interests and noncontrolling interests

recognized in acquisitions, the valuations of common shares prior to IPO and share-based awards, and accruals for research and development costs.

The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. Actual results may differ from those estimates or assumptions.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. As of June 30, 2022 and December 31, 2021, cash and cash equivalents consisted of cash on deposit and cash held in high-yield savings accounts and money market funds.

Investment Securities Portfolio

Investment Securities Portfolio

The following table sets forth the fair value of atai's available-for-sale securities portfolio at the dates indicated:

	Fair Value
	June 30, 2022		December 31, 2021
Money Market Funds	$	38,878	$	—
U.S. Treasuries		3,478		—
Commercial Paper		114,880		—
Corporate Notes/Bonds		107,045		—
U.S. Government Agencies		2,951		—
	$	267,232	$	—

In January 2022, the Company invested in a certain investment portfolio, which is comprised of Money Market Funds, U.S. Treasury securities, Commercial Paper, Corporate Notes/Bonds, and U.S. government agencies securities. The Company classified securities in the investment portfolio as available-for-sale securities. Furthermore, the Company elected the fair value option for the available-for-sale securities in the investment portfolio (see Note 7). The decision to elect the fair value option, which is irrevocable once elected, is determined on an instrument-by-instrument basis and applied to an entire instrument. The net gains or losses, if any, on an investment for which the fair value option has been elected are recognized as a change in fair value of securities on the Consolidated Statements of Operations and the amortized cost of investments approximates their fair value.

Fair Value Measurements

Fair Value Measurements

Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s contingent consideration liability—related parties, derivative liability associated with the Perception convertible promissory notes, IntelGenx Initial Warrants and IntelGenx Additional Units Warrant, and warrant liability with Neuronasal Inc. are carried at fair value, determined according to Level 3 inputs in the fair value hierarchy described above (See Note 7). The IntelGenx common stock and securities carried at fair value are determined according to Level 2 inputs in the fair value hierarchy above. The carrying amount reflected in the accompanying consolidated balance sheets for cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values, due to their short-term nature.

The carrying amounts of the Company’s remaining outstanding convertible promissory notes—related parties issued in 2018 and 2020 (collectively, the “2018 Convertible Notes”) do not approximate fair value because the fair value is driven by the underlying value of the Company’s common shares into which the notes are to be converted. As of June 30, 2022, the carrying amount and fair value amount of the 2018 Convertible Notes was $0.6 million and $28.8 million, respectively. As of December 31, 2021, the carrying amount and fair value amount of the 2018 Convertible Notes was $0.8 million and $69.7 million, respectively. Subsequent to the IPO, several noteholders of the 2018 Convertible Notes elected to convert their promissory notes into the Company's common shares. See Note 10 for additional discussion.

Fair Value Option

Fair Value Option

As permitted under Accounting Standards Codification 825, Financial Instruments, or ASC 825, the Company has elected the fair value option to account for its investment in common shares of IntelGenx, which otherwise would be subject to ASC 323. In accordance with ASC 825, the Company records this investment at fair value under Other investments held at fair value in the Company's consolidated balance sheets and changes in fair value are recognized as a component of other income (expense), net in the consolidated statements of operations. The carrying value of the investment remained at zero as of June 30, 2022 and December 31, 2021, respectively.

Furthermore, as noted above the Company also elected the fair value option for its investment securities portfolio.

Emerging Growth Company Status

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

As described in “Recently Adopted Accounting Pronouncements” below, the Company early adopted certain accounting standards, as the JOBS Act does not preclude an emerging growth company from adopting a new or revised accounting standard earlier than the time that such standard applies to private companies. The Company expects to use the extended transition period for any other new or revised accounting standards during the period in which it remains an emerging growth company.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is a comprehensive new lease standard that amends various aspects of existing accounting guidance for leases. The core principle of Topic 842 requires lessees to recognize on the consolidated balance sheets a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases with lease terms greater than twelve months. The lease liability is measured at the present value of the unpaid lease payments and the right-of-use asset is derived from the calculation of the lease liability. Topic 842 also requires lessees to disclose key information about leasing arrangements. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. As a result of the Company having elected the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act, ASU 2016-02 is effective for the Company beginning after December 15, 2021.

The Company adopted the new standard on January 1, 2022 using the modified transition approach as of the effective date.

The new standard provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permitted it to not reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs. As a result, the Company has continued to account for existing leases - i.e. leases for which the commencement date is before January 1, 2022 - in accordance with Topic 840 throughout the entire lease term, including periods after the effective date, with the exception that the Company applied the new balance sheet recognition guidance for operating leases and applied Topic 842 for remeasurements and modifications after the Transition Date. The Company also elected the hindsight expedient in determining the lease term and assessing impairment of right-of-use assets when transitioning to ASC 842. As a result, the Company evaluated the lease term for its existing leases as of the transition date, January 1, 2022.

The most significant impact of the adoption of Topic 842 on the Company’s condensed consolidated financial statements was the recognition of a $0.2 million operating lease right-of-use asset, a $0.1 million current operating lease liability, and a $0.1 million long-term operating lease liability on the Company’s condensed consolidated balance sheet related to its existing facility operating lease. The Company did not have a deferred rent liability recorded in connection with its existing facility operating lease. There was no material impact to the Company’s condensed consolidated balance sheet, statement of operations, and no cumulative-effect adjustment to

accumulated deficit. The Company recorded an immaterial amount of general and administrative expense in its consolidated statement of operations related to lease expense, including short-term lease expense during the three and six months ended June 30, 2022.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses. This update requires immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred. The new model is applicable to most financial assets and certain other instruments that are not measured at fair value through net income. In November 2019, the FASB issued ASU 2019-10, which delays adoption for "smaller reporting companies" as defined under the rules promulgated under the Exchange Act. Although, as of December 31, 2021, the Company was no longer a smaller reporting company, the Company qualified as a smaller reporting company at the time of its initial public offering and, as such, in accordance with ASU 2019-10, the effective date for adoption by the Company will begin after December 31, 2022. The Company does not expect that the adoption of this new standard will have a material impact on its condensed consolidated financial statements and related disclosures.
