EADERSHIP

S

TRUCTURE

The Board has an independent chair, Dr. Russo, who has authority, among other things, to develop and approve an appropriate Board meeting schedule and meeting agendas in consultation with the Chief Executive Officer, convene, moderate and develop the agendas for meetings of the independent members of the Board, and preside over Board meetings when the Chief Executive Officer is not present or when Board or Chief Executive Officer performance or compensation is discussed. Accordingly, the Board Chair has substantial ability to shape the work of the Board. The Company believes that separation of the positions of Board Chair and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of the Company. In addition, the Company believes that having an independent Board Chair creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of the Company and its stockholders. As a result, the Company believes that having an independent Board Chair can enhance the effectiveness of the Board as a whole.

VERSIGHT

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company and ways to address those risks.

Our Audit Committee has the responsibility to review and discuss with management and our independent registered public accounting firm, as appropriate, the Company’s guidelines and policies with respect to financial risk management and financial risk assessment, including the Company’s major financial risk exposures and the steps our management has taken to monitor and control these exposures. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function. Audit Committee responsibilities also include oversight of management risks relating to data privacy, technology and information security, including cyber security and

back-up

of information systems, and the steps the Company has taken to monitor and control such exposures. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. The committee also oversees and reviews with management the Company’s major legal compliance risk exposures and the steps management has taken to monitor or mitigate such exposures, including the Company’s procedures and any related policies with respect to risk assessment and risk management. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Both the Board as a whole and the various standing committees receive periodic reports regarding material enterprise risks, as well as incidental reports as matters may arise.

(5) Dr. Shah resigned from the Compensation Committee on November 19, 2021 in connection with Dr. Miller’s appointment to the Board and the Compensation Committee.

Below is a description of each committee of the Board.

Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems

appropriate to carry out its responsibilities. The Board has previously determined that each member of each committee meets the applicable Nasdaq rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

Audit Committee

The Audit Committee was established by the Board in accordance with Section 3(a)(58)(A) of the Exchange Act, to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions. The principal duties and responsibilities of our Audit Committee include, among other things:

• evaluate the performance and assesses the independence and qualifications of the independent auditors;

• determine and approve the engagement of the independent auditors;

• determine whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors;

7

• review and approve the retention of the independent auditors to perform any proposed permissible non-audit services;

• monitor the rotation of partners of the independent auditors on the Company’s audit engagement team as required by law;

• confer with management and the independent auditors regarding the effectiveness of internal control over financial reporting;

• establish procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and

• meet to review the Company’s annual audited financial statements and quarterly financial statements with management and the independent auditor, including a review of the Company’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and to recommend whether such financial statements should be included in our Annual Report on Form 10-K and Annual Report on 10-Q, as applicable.

The Audit Committee is composed of three directors: Tomas Heyman, René Russo, Pharm.D., and Michael Wyzga. The Audit Committee met four times during the last fiscal year. The Board has adopted a written Audit Committee charter that is available on the Company’s website at https://investors.adagiotx.com/.

The Board reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards).

The Board has also determined that Mr. Wyzga qualifies as an “audit committee financial expert,” as defined in applicable Commission rules. The Board made a qualitative assessment of Mr. Wyzga’s level of knowledge and experience based on a number of factors, including his formal education and his experience as a chief executive officer, chief financial officer and member of the audit committee of the boards of directors of other public companies.

Compensation Committee

The Compensation Committee is composed of three directors: Howard Mayer, M.D., Redonda Miller, M.D., M.B.A., and Michael Wyzga. All members of the Company’s Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq listing standards). The Compensation Committee met five times during the last fiscal year. The Board has adopted a written Compensation Committee charter that is available on the Company’s website at https://investors.adagiotx.com/.

The Compensation Committee acts on behalf of the Board to review, adopt (or recommend to the Board for adoption) and oversee the Company’s compensation strategy, policies, plans and programs, including:

• review and approval (or review and recommendation to the Board for approval) of corporate and individual performance objectives relevant to the compensation of the Company’s executive officers and other senior management and evaluation of performance in light of these stated objectives;

• review and approval (or review and recommendation to the Board for approval) of the compensation and other terms of employment or service, including severance and change-in-control arrangements, of the Company’s executive officers and other senior management;

• administration of the Company’s equity compensation plans and any other similar plans and programs that the Compensation Committee may evaluate and approve from time to time, such as pension and profit-sharing plans or deferred compensation plans; and

• review and recommend to the Board the type and amount of compensation to be paid or awarded to non-employee directors.

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer and Pearl Meyer, the compensation consultant engaged by the Compensation Committee. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation

or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under its charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and consultants that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than

in-house

legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the Commission and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During the last fiscal year, after taking into consideration the six factors prescribed by the Commission and Nasdaq described above, the Compensation Committee engaged Pearl Meyer as compensation consultants. The Compensation Committee identified Pearl Meyer based on Pearl Meyer’s general reputation in the industry. The Compensation Committee requested that Pearl Meyer:

• evaluate the efficacy of the Company’s existing compensation strategy and practices in supporting and reinforcing the Company’s long-term strategic goals; and

• assist in refining the Company’s compensation strategy and in developing and implementing an executive compensation program to execute that strategy.

9

As part of its engagement, Pearl Meyer was requested by the Compensation Committee to develop a comparative group of companies and to perform analyses of competitive performance and compensation levels for that group. At the request of the Compensation Committee, Pearl Meyer also conducted individual interviews with members of the Compensation Committee and senior management and other employees identified by the Committee to learn more about the Company’s business operations and strategy, key performance metrics and strategic goals, as well as the labor markets in which the Company competes. Pearl Meyer ultimately developed recommendations that were presented to the Compensation Committee for its consideration. Following an active dialogue with Pearl Meyer and resulting modifications, the Compensation Committee approved the modified recommendations of Pearl Meyer. Under its charter, the Compensation Committee may form, and delegate authority to, subcommittees as appropriate. In fiscal year 2021, at the recommendation of the Compensation Committee, the Board delegated authority under the Company’s 2021 Equity Incentive Plan to our Chief Executive Officer to grant options to employees who are not executive officers, subject to limitations approved by the Compensation Committee. The purpose of this delegation of authority is to enhance the flexibility of option administration within the Company and to facilitate the timely grant of options to

non-management

employees, particularly new employees, within specified limits recommended by the Compensation Committee and approved by the Board. In particular, the Chief Executive Officer may not grant options to acquire more than an aggregate of 7,000,000 shares per year, and individually in accordance with minimum and maximum limits for each employee’s classification set forth in the Company’s

non-executive

employee equity grant guidelines. During fiscal year 2021, the Chief Executive Officer exercised his authority to grant options to purchase an aggregate of 832,200 shares to

non-officer

employees.

Other than in connection with our initial public offering during the last fiscal year, the Compensation Committee makes most of the significant adjustments to annual compensation, determines bonus and equity awards and establishes new performance objectives at one or more meetings held during the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of the Board, and developing a set of corporate governance guidelines and principles for the Company.

The Nominating and Corporate Governance Committee is composed of three directors: Tomas Heyman, Ellen R. Marram, M.B.A., and Anand Shah, M.D. All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards). The Nominating and Corporate Governance Committee met one time during the last fiscal year. The Board has adopted a written Nominating and Corporate Governance Committee charter that is available on the Company’s website at https://investors.adagiotx.com/.

Consistent with the criteria for director qualifications set by the Board, the Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity (including gender, racial and ethnic diversity and sexual orientation), age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. As presently constituted, the Board represents a deliberate mix of members who have a deep understanding of the Company’s business, as well as members who have different skill sets and points of view on substantive matters pertaining to our business. Our nomination process and the Nominating and Corporate Governance Committee’s approach to assessment and evaluation of nominees support our commitment to diversity and inclusion.

The Nominating and Corporate Governance Committee appreciates the value of thoughtful Board refreshment, and regularly identifies and considers qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the Committee reviews these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The Nominating and Corporate Governance Committee also takes into account the results of the Board’s self-evaluation, which is conducted annually. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent, which determination is based upon applicable Nasdaq listing standards, applicable Commission rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote. In fiscal year 2021, the Nominating and Corporate Governance Committee paid a fee to Klein Hirsch to assist in the process of identifying or evaluating director candidates.

11

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 1601 Trapelo Road, Suite 178, Waltham, Massachusetts 02451, Attn: Corporate Secretary, at least 90 days, but not less than 120 days, prior to the anniversary date of the mailing of the Company’s proxy statement for the last annual meeting of stockholders. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and the name and address of the stockholder on whose behalf the submission is made and the number and class of shares owned beneficially by such stockholder, in addition to the information specified in the Bylaws. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

The Compensation Committee of our Board has historically determined our executives’ compensation, including the compensation of our named executive officers. Our Compensation Committee typically reviews and discusses management’s proposed compensation with the Chief Executive Officer for all executives other than the Chief Executive Officer. The Compensation Committee also reviews and discusses the recommendations of the Compensation Committee’s compensation consultant, including analyses of executive compensation paid at other companies identified by the consultant. Based on those discussions and its discretion, the Compensation Committee then approves, or recommends to the Board for approval, the compensation of each executive officer without members of management present.

Annual Base Salary

The annual base salaries of our named executive officers are determined, approved and reviewed by our Compensation Committee. Annual base salaries are intended to provide a fixed component of compensation to our named executive officers, reflecting their skill sets, experience, roles and responsibilities. Base salaries for our named executive officers have generally been set at levels necessary to attract and retain individuals with superior talent.

The following table sets forth the annual base salaries for Dr. Gerngross and Mr. Hering for 2021, effective as of the closing of our initial public offering on August 10, 2021, and for Ms. Andersen for 2021, effective as of the commencement of her employment with the Company in November 2021, as determined by the Compensation Committee:

Name	2021 Base Salary ($)
Tillman U. Gerngross	$	550,000
David Hering, M.B.A.	$	410,000
Jill Andersen, J.D.	$	400,000

In January 2022, the Compensation Committee recommended to the Board the following annual base salaries for each of our named executive officers for 2022, which the Board approved in February 2022:

Name	2022 Base Salary ($)
Tillman U. Gerngross	$	619,000
David Hering, M.B.A. (1)	$	459,000
Jill Andersen, J.D.	$	428,000

(1)  In March 2022, the Board approved an increase in Mr. Hering’s base salary for 2022 to $510,000, with retroactive effectiveness to February 23, 2022, and further approved the payment of a monthly stipend of $7,500 in addition to Mr. Hering’s base salary, in connection with his appointment as Interim Chief Executive Officer.

Non-Equity Incentive

Plan Compensation

The Compensation Committee develops a performance-based bonus program annually. For 2021, the Compensation Committee determined that each named executive officer’s performance bonus should be based principally on contribution towards the achievement of corporate goals. Under the 2021 annual performance bonus program, each named executive officer was eligible to be considered for an annual performance bonus based on the percentage attainment, as determined by the Compensation Committee, of the 2021 corporate goals that were previously approved by the Board. The Compensation Committee retained the discretion to make adjustments to the calculated bonus amount based on unexpected or unplanned events, the overall financial condition of the Company, extraordinary performance or underperformance or other factors deemed appropriate by the Compensation Committee. Each named executive officer has a target bonus opportunity calculated as a percentage of his or her annual base salary

15

and may earn more or less than the annual target amount based on the Company’s achievement of the performance goals and the adjustments described above. For 2021, Dr. Gerngross’s target bonus percentage was 50% and each of Mr. Hering and Ms. Andersen’s target bonus percentage was 40%. In February 2022, the Compensation Committee determined that the percentage attainment of the target bonus for 2021 was 111% for each named executive officer and approved individual performance achievement payouts for each named executive officer in the amounts reflected in the column of the Summary Compensation Table above entitled

“Non-Equity

Incentive Plan Compensation.”

Equity-Based Awards

Our equity-based incentive awards granted to our named executive officers are designed to align the interests of our named executive officers with those of our stockholders. Vesting of equity awards is generally tied to each officer’s continuous service with us and serves as an additional retention measure. Our executives generally are awarded an initial new hire grant upon commencement of employment and thereafter on an annual basis. Additional grants may occur periodically in order to specifically incentivize executives with respect to achieving certain corporate goals, to reward executives for exceptional performance or compensate executives for additional job responsibilities.

Prior to our initial public offering, we granted all equity awards pursuant to our 2020 Equity Incentive Plan. Since the closing of our initial public offering, we grant all equity awards pursuant to our 2021 Equity Incentive Plan.

Retirement Benefits and Other Compensation

Our named executive officers did not participate in, or otherwise receive any benefits under, any pension, retirement or deferred compensation plan sponsored by us during 2021 other than our 401(k) plan described below. During 2021, our named executive officers were eligible to participate in our employee benefit plans, including health insurance and group life insurance benefits, on the same basis as our other employees. We maintain a safe harbor 401(k) plan that provides eligible employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation up to certain limits of the Code, which are updated annually. The 401(k) plan also provides that we will make

non-elective

contributions to each participant’s account totaling to 3% of the participant’s eligible compensation. We generally do not provide other perquisites or personal benefits except in limited circumstances, and we did not provide any such perquisites or personal benefits to our named executive officers in 2021.

Employment Agreements with our Named Executive Officers

We entered into an employment agreement with Dr. Gerngross and an amended and restated employment agreement with Mr. Hering in connection with the closing of our initial public offering, and an employment agreement with Ms. Andersen in connection with her commencement of employment with us, that each include an initial annual base salary and annual target bonus. The annual bonus is determined by the Compensation Committee based on the achievement of performance goals and objectives for the calendar year. Each employment agreement provides for standard benefits, such as paid time off, reimbursement of business expenses, and participation in our employee benefit plans and programs. Each employment agreement states that any time-based equity issued on or after the closing of our initial public offering would not accelerate in full upon a change in control if such equity was assumed, continued or substituted by the successor entity. Substantive differences are limited to (i) the definition of Good Reason, which, for Mr. Hering and Ms. Andersen, is further triggered by a material reduction in the authority, duties or responsibilities of the CEO to whom the executives report and (ii) the promise of a grant of an initial option award, subject to the approval of the Board, in the case of Ms. Andersen. Severance terms are detailed further below under “Potential Payments Upon Termination or Change in Control.” Each of our named executive officers’ compensation has been subsequently increased from time to time to the amounts described above. We do not maintain any other offer letters or employment agreements with our named executive officers.

Potential Payments Upon Termination or Change in Control

Dr. Gerngross was, and Mr. Hering and Ms. Andersen are, entitled to certain severance and change in control benefits pursuant to the employment agreements described above.

In the event that the executives’ employment ends upon death or a disability, they are entitled to accrued obligations and payment of their target bonus so long as their employment terminates after the completion of the calendar year but prior to the date of payment of the bonus, or the Earned Bonus.

In the event that employment terminates, other than during the period commencing three months prior to or ending 12 months following a “change in control,” or the Change in Control Period, by us without “cause��� or by the executive for “good reason” (as defined in our equity plan and the respective employment agreement), and subject to the delivery to us of a separation agreement that includes a general release of claims, Mr. Hering and Ms. Andersen will each receive cash severance equal to 9 months of their base salary, as well as the Earned Bonus, if applicable, and 9 months continuation of benefits, and will be entitled to delayed forfeiture of unvested time-based equity awards until 90 days after the date of termination. Dr. Gerngross was entitled to receive cash severance equal to 12 months of

17

his base salary, the Earned Bonus, if applicable, and 12 months continuation of benefits, and would be entitled to delayed forfeiture of unvested time-based equity awards until 90 days after the date of termination. No severance payments were made pursuant to Dr. Gerngross’s employment agreement upon his resignation.

In the event that the executives’ employment is terminated by us without cause or by the executive for good reason, in either case, during the Change in Control Period, and subject to their delivery to us of a separation agreement that includes a general release of claims, Mr. Hering and Ms. Andersen will each receive cash severance equal to 12 months of their base salary, their respective target bonus for the year of termination, as well as the Earned Bonus, if applicable, and 12 months continuation of benefits, and will be entitled to immediate acceleration and full vesting of any time-based equity awards, exercisable or nonforfeitable as if employment continued until the later of the date of termination or the effective date of the separation agreement. Dr. Gerngross was entitled to receive cash severance equal to 18 months of his base salary, the target bonus for the year of termination with a 1.5 multiplier, the Earned Bonus, if applicable, and 18 months continuation of benefits and would be entitled to immediate acceleration and full vesting of any time-based equity awards, exercisable or nonforfeitable as if employment continued until the later of the date of termination or the effective date of the separation agreement.

Narrative to Director Compensation Table

Our Board adopted a

non-employee

director compensation policy that became effective in August 2021 in connection with the closing of our initial public offering. Pursuant to this compensation policy, each of our directors who is not an employee or consultant of our company is eligible to receive compensation for service on our Board and committees of our Board.

Under our compensation policy, each eligible director receives an annual cash retainer in the amount of $40,000 for serving on our Board. In addition, the Chair of our Board receives an annual cash retainer in the amount of $30,000 (in addition to the annual cash retainer given to all eligible directors). The chairperson of the Audit Committee of our Board is entitled to receive an additional annual cash retainer in the amount of $15,000, the chairperson of the Compensation Committee of our Board is entitled to receive an additional annual cash retainer in the amount of $10,000 and the chairperson of the Nominating and Corporate Governance Committee of our Board is entitled to receive an additional annual cash retainer in the amount of $8,000. The other members of the Audit Committee are entitled to receive an additional annual cash retainer in the amount of $7,500, the other members of the Compensation Committee are entitled to receive an additional cash retainer in the amount of $5,000 and the other members of the Nominating and Corporate Governance Committee are entitled to receive an additional annual cash retainer in the amount of $4,000.

In addition, each new eligible director who joins our Board is entitled to receive a

non-statutory

stock option to purchase shares of our common stock with an aggregate Black-Scholes grant date value of $800,000, up to a maximum of 150,000 shares, with

one-third

of the shares vesting on the first anniversary of the grant date and 1/36

th

of the shares vesting in equal monthly installments thereafter, subject to continued service as a director through the vesting dates.

On the date of each annual meeting of our stockholders, each eligible director who continues to serve as a director of our Company following the meeting is entitled to receive a

non-statutory

stock option to purchase shares of our common stock with an aggregate Black-Scholes grant date fair value of $400,000, up to a maximum of 75,000 shares, with the shares vesting on the earlier of the first anniversary of the date of grant or the next annual meeting of our stockholders, subject to continued service as a director though the applicable vesting dates. If an eligible director joins our Board upon or after the date of the last preceding annual stockholders meeting, such eligible director’s Annual Grant will be

pro-rated

based on days served since joining our Board.

19

The aggregate value of all compensation granted or paid, as applicable, to any individual for service as

a Non-Employee Director

with respect to any calendar year will not exceed $1,500,000 in total value, calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes.

Each option awarded to eligible directors under the

non-employee

director compensation policy will be subject to accelerated vesting upon a change in control transaction. The exercise price per share of each stock option granted under the

non-employee

director compensation policy will be equal to the closing price of our common stock on the Nasdaq Global Market on the date of grant. Each stock option will have a term of ten years from the date of grant, subject to earlier termination in connection with a termination of the eligible director’s continuous service with us (provided that upon a termination of service other than for cause, the post-termination exercise period will be 12 months from the date of termination or death, if earlier).

In October 2020, we adopted an independent director compensation policy pursuant to which our independent directors were entitled to receive an annual cash retainer of $35,000 for serving on our Board, payable in arrears on a quarterly basis. In addition, each independent director who was appointed or elected following the policy’s adoption was entitled to be granted an option to purchase 0.25% of our outstanding shares issuable at the start of the director’s term at an exercise price equal to the fair market value of our common stock on the date of grant, with 25% of the underlying shares vesting on the first anniversary of the grant date and the remainder vesting in 36 equal monthly installments thereafter, subject to the director’s continued service through the applicable vesting date. While Dr. Russo and Dr. Mayer were both independent directors eligible to receive compensation in 2021 under this policy, only Dr. Mayer has received compensation pursuant to this policy because Dr. Russo received compensation pursuant to a consulting agreement described below and received an option award as

a co-founder of

the Company. This policy was terminated in connection with our initial public offering.

In June 2020, we entered into a consulting agreement with Dr. Russo pursuant to which Dr. Russo was entitled to receive $7,500 per month, with payment for any partial months prorated. In addition, Dr. Russo’s consulting agreement provided that she was eligible for an annual additional consulting fee at the discretion of our Board. Such annual additional consulting fee had a target amount of $40,500, but the actual amount of the annual additional consulting fee was to be determined by our Board in its discretion. This consulting agreement was terminated in connection with our initial public offering.

The following table sets forth certain information regarding the ownership of the Company’s common stock as of March 29, 2022 by: (i) each director and nominee for director; (ii) each of the executive officers named in the Summary Compensation Table; (iii) all executive officers and directors of the Company as a group; and (iv) all those known by the Company to be beneficial owners of more than five percent of its common stock. Applicable percentages are based on 109,675,173 shares outstanding on March 29, 2022, adjusted as required by rules promulgated by the Commission.

Beneficial ownership is determined according to the rules of the Commission and generally means that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power of that security, including options that are currently exercisable or exercisable within 60 days of March 29, 2022. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons named in the table below have sole voting and investment power with respect to all shares of common stock shown that they beneficially own, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose.

Common stock subject to stock options currently exercisable or exercisable within 60 days of March 29, 2022 are deemed to be outstanding for computing the percentage ownership of the person holding these options and the percentage ownership of any group of which the holder is a member but are not deemed outstanding for computing the percentage of any other person.

Unless noted otherwise, the address of all listed directors and executive officers is c/o Adagio Therapeutics, Inc., 1601 Trapelo Road, Suite 178, Waltham, Massachusetts 02451.

Assignment and License Agreement

In July 2020, we entered into an assignment and license agreement, or the Adimab Assignment Agreement, with Adimab pursuant to which Adimab assigned to us all coronavirus antibodies controlled by it and their derivatives, patents claiming such

antibodies, know-how related

to such antibodies, and biological and chemical materials specifically related to such antibodies, and also granted us

a non-exclusive, sublicensable,

worldwide, royalty-bearing license to certain of its platform technology to research, develop, make, use and sell coronavirus antibodies and products containing or comprising coronavirus antibodies. In connection with the transfer of the rights acquired and license received, we issued to Adimab 5,000,000 shares of our Series A preferred stock, then having a fair value of $40.0 million. Concurrently, Adimab relinquished to us 21,250,000 shares of our common stock, then having a fair value of $85,000. As of March 29, 2022, Adimab held approximately 24.3% of our outstanding capital stock.

27

Under the Adimab Assignment Agreement, we are obligated to pay Adimab quarterly for its services performed under the agreement at a specified full-time equivalent rate. We are obligated to pay Adimab up to $24.6 million upon the achievement of specified development and regulatory milestones for the first two products that comprise or contain coronavirus antibodies assigned to us, antibodies discovered or optimized under the Adimab Assignment Agreement, or any derivative of such antibody, or the Products. We are also obligated to pay Adimab royalties of a mid single-digit percentage based on annual aggregate worldwide net sales of any Products, subject to reductions for third-party licenses, biosimilar competition, compulsory licensing and a royalty floor.

In February 2021, we achieved the first specified milestone under the agreement upon dosing of the first patient in a Phase 1 clinical trial evaluating adintrevimab, which obligated us to make a $1.0 million payment to Adimab. We made the payment in March 2021. In April 2021, we achieved the second specified milestone under the agreement upon dosing of the first patient in a Phase 2 clinical trial evaluating adintrevimab for the prevention of

COVID-19, which

obligated us to make a $2.5 million payment to Adimab. We made the payment in June 2021. In August 2021, we achieved the third specified milestone under the agreement upon dosing of the first patient in a Phase 3 clinical trial evaluating adintrevimab for the prevention of

COVID-19,

which obligated us to make a $4.0 million payment to Adimab. We made the payment in September 2021.

During the fiscal year ended December 31, 2021, we paid Adimab $8.7 million in connection with services provided under the Adimab Assignment Agreement. As of December 31, 2021, $0.4 million was due to Adimab by us.

Collaboration Agreement

In May 2021, we entered into a collaboration agreement with Adimab, or the Adimab Collaboration Agreement, pursuant to which we and Adimab will collaborate on the discovery and optimization of proprietary antibodies as potential therapeutic product candidates. We were obligated to pay Adimab a quarterly fee of $1.3 million in exchange for Adimab and its affiliates agreeing not to assist in the discovery or optimization of or to direct certain third parties to discover or optimize antibodies that are intended to bind to coronaviruses or influenza viruses, which obligation may be cancelled at our option at any time.

For each agreed upon research program that is commenced, we are obligated to pay Adimab quarterly for its services performed during a given research program at a specified full-time equivalent rate; a discovery delivery fee of $0.2 million; and an optimization completion fee of $0.2 million. For each option exercised by us to commercialize a specific research program, we are obligated to pay Adimab an exercise fee of $1.0 million.

We are obligated to pay Adimab up to $18.0 million upon the achievement of specified development and regulatory milestones for each product under the agreement that achieves such milestones. We are also obligated to pay Adimab royalties of a mid single-digit percentage based on annual aggregate worldwide net sales of products, subject to reductions for third-party licenses.

In addition, we are obligated to pay Adimab for Adimab’s performance of certain validation work with respect to certain antigens acquired from a third party. In consideration for this work, we are obligated to pay Adimab royalties of a low single-digit percentage based on annual aggregate worldwide net sales of products that contain such antigens for the same royalty term as antibody-based products, but we are not obligated to make any milestone payments for such antigen products.

28

During the fiscal year ended December 31, 2021, we paid Adimab $2.6 million in connection with services provided under the Adimab Collaboration Agreement. As of December 31, 2021, $0.2 million was due to Adimab by us.

Investors’ Rights, Voting and Right of First Refusal Agreements

In connection with the sale of our preferred stock described above, we entered into an amended and restated investors’ rights agreement, an amended and restated voting agreement and an amended and restated right of first refusal

and co-sale agreement

containing registration rights, information rights, voting rights and rights of first refusal, among other things, with the holders of our preferred stock. These agreements terminated upon the closing of our initial public offering, except for the registration rights granted under our amended and restated investors’ rights agreement, which terminate with respect to each holder upon the earlier of such holder being able to sell such holder’s shares without limitation during a three-month period pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended, and the fifth anniversary of the closing of our initial public offering. The registration rights provisions of this agreement provide those holders with demand, piggyback and Form

S-3

registration rights with respect to the shares of common stock currently held by them. See “—Private Placements of Our Securities—Series C Preferred Stock Financing” above for information regarding the names of the related persons involved and the basis on which such persons are related persons.

Indemnification

The Company provides indemnification for its directors, executive officers and key employees so that they will be free from undue concern about personal liability in connection with their service to the Company. Under the Bylaws, the Company is required to indemnify its directors, and is permitted to indemnify its executive officers, employees and other agents, to the extent not prohibited under Delaware or other applicable law. The Company has also entered into indemnity agreements with certain officers and directors. These agreements provide, among other things, that the Company will indemnify the officer or director, under the circumstances and to the extent provided for in the agreement, for expenses, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and the Bylaws.

Director Independence

As required under the Nasdaq listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the Board. The Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

During 2021, the Board considered the independence of its directors and concluded that Tomas Heyman, Ellen Marram, Howard Mayer, Redonda Miller, Rene Russo, Anand Shah and Michael Wyzga were independent directors in accordance with Rule 5605(a)(2) of the Nasdaq Listing Rules. The Board made these determinations after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors. In making these determinations, the Board found that none of these directors had a material or other disqualifying relationship with the Company.
