Our Board of Directors and Compensation Committee review compensation annually for all employees, including our executives. In setting executive base salaries and annual incentives and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, internal equity, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders and a long-term commitment to Magenta. We target a general competitive position, based on independent third-party benchmark analytics to inform the mix of compensation of base salary, annual incentives or long-term incentives.

Our Compensation Committee is responsible for determining the compensation for senior management of the Company, other than the chief executive officer. Our Board of Directors, with the recommendation of the Compensation Committee, is responsible for determining the compensation of our chief executive officer. Our Compensation Committee typically reviews and discusses management’s proposed compensation with the chief executive officer for all senior management other than the chief executive officer. Based on those discussions and its discretion, taking into account the factors noted above, the Compensation Committee then sets the compensation for senior management, other than the chief executive officer, and recommends the compensation for the chief executive officer to our Board of Directors for approval. Our Board of Directors discusses the Compensation Committee’s recommendation and ultimately approves the compensation of our chief executive officer without members of management present.
In 2022, the Compensation Committee retained the services of Pay Governance LLC (“Pay Governance”) as its external independent compensation consultant. In this role, Pay Governance served as an advisor to the Compensation Committee on topics primarily related to our broader compensation structure, executive new hire compensation packages, executive compensation structure, peer group review, benchmarking of executive positions and equity share usage and dilution. In addition, Pay Governance provided advice regarding corporate governance and regulatory environment trends. Our Board of Directors and the Compensation Committee considered Pay Governance’s input on certain compensation matters as they deemed appropriate. The Compensation Committee requires that its compensation consultants be independent of management and performs an annual assessment of the compensation consultants’ independence to determine whether the consultants are independent. After review of the independence factors set forth by Nasdaq and the SEC, the Compensation Committee determined that the engagement of Pay Governance does not raise any conflict of interest.
Annual base salary
Each named executive officer’s base salary is a fixed component of annual compensation for performing specific duties and functions and has been established by our Compensation Committee or Board of Directors, as applicable, taking into account each individual’s role, responsibilities, skills, and experience. Base salaries for our named executive officers are reviewed annually by our Compensation Committee or Board of Directors, as applicable, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, internal equity, performance, and experience.
Cash annual incentive
Our annual incentive program is intended to reward our named executive officers for meeting objective or subjective performance goals for a fiscal year. From time to time, our Compensation Committee or Board of Directors, as applicable, may approve annual incentives for our named executive officers based on individual performance, company performance, or as otherwise determined appropriate. Each of our named executive officers was eligible to receive a target bonus with respect to 2022 (as a percentage of base salary as set forth below) based upon the achievement of corporate performance goals related to, among other things, execution on key development pipeline objectives, the delivery of clinical data, the advancement of key manufacturing objectives, identification of new programs and the ensuring of financial and organizational stability. The Compensation Committee determined that corporate goals were achieved for the 2022 annual incentive at up to 110% of target, and based on the recommendation of management, the Board of Directors ultimately approved 105% of target.

Compensation Risk Assessment
We believe that although a portion of the compensation provided to our executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Under our director compensation program, we pay our non-employee directors a cash retainer for service on our Board of Directors and for service on each committee on which the director is a member. The chair of each committee receives a higher retainer for such service. These fees are payable in arrears in four equal quarterly installments pro-rated based on the number of actual days served by the director during such calendar quarter. The fees paid to non-employee directors for service on our Board of Directors and for service on each committee of our Board of Directors on which the director is a member are as follows:

We also reimburse our non-employee directors for reasonable travel and out-of-pocket expenses incurred in connection with attending our Board of director and committee meetings.
In addition, each new non-employee director elected to our Board of Directors is granted an initial, one-time equity award of a stock option to purchase 40,000 shares of our common stock which vests 33% on the first anniversary of the grant, with the remainder vesting monthly in equal installments over the following two years, provided, however, that all vesting shall cease if the director resigns from our Board of Directors or otherwise ceases to serve as a director of Magenta. On the date of each annual meeting of stockholders of Magenta, each continuing non-employee director receives an annual equity award of a stock option to purchase 20,000 shares, which vests in full upon the earlier to occur of the first anniversary of the date of grant or the date of the next annual meeting; provided, however, that vesting shall cease if the director resigns from our Board of Directors or otherwise ceases to serve as a director, unless our Board of Directors determines that the circumstances warrant continuation of vesting. Each such option grant shall have a per share exercise price equal to the Fair Market Value (as defined in the Company’s 2018 Stock Option and Incentive Plan) of the Company’s common stock on the date of such grant.
This program is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors’ interests with those of our stockholders.

| (2) | Consists of 8,475,816 shares issuable upon the exercise of outstanding options under the 2016 Plan and the 2018 Plan and 427,244 shares issuable upon the vesting of restricted stock units. This does not include purchase rights under the 2019 ESPP because the purchase right (and therefore the number of shares to be purchased) will not be determined until the end of the current purchase period. Since restricted stock units do not have any exercise price, such units are not included in the weighted average exercise price calculation. |
| (3) | As of December 31, 2022, there were 3,102,231 shares available for grant under the 2018 Plan and 593,239 shares available for purchase under the 2019 ESPP. |
| (4) | The 2018 Plan has an evergreen provision whereby the number of shares of common stock reserved and available for issuance under the 2018 Plan is subject to an automatic annual increase on each January 1, beginning in 2019, by an amount equal to four percent of the number of shares of common stock issued and outstanding on the immediately preceding December 31 or such lesser number of shares of common stock as determined by the Administrator (as defined in the 2018 Plan). Accordingly, on January 1, 2023, the number of shares of common stock reserved and available for issuance under the 2018 Plan increased by 2,425,596 shares. The number in column (c) does not include such shares. |
The 2019 ESPP has an evergreen provision whereby the number of shares of common stock reserved and available for purchase under the 2019 ESPP is subject to an automatic increase on each January 1, beginning in 2020, by the lesser of (i) 1% of the number of shares issued and outstanding on the immediately preceding December 31, (ii) 1,000,000 shares and (iii) such number of shares as determined by the Administrator (as defined in the 2019 ESPP). Our Compensation Committee, as Administrator of the 2019 ESPP, determined not to increase the number of shares reserved for purchase under the 2019 ESPP on January 1, 2023.

Certain Relationships and Transactions
Other than the compensation agreements and other arrangements described under “Executive Compensation” and “Director Compensation” in this Form 10-K/A and the transactions described below, since January 1, 2021, there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which the amount involved exceeded, or will exceed, $120,000 (or, if less, 1% of the average of our total assets amounts at December 31, 2021 and 2022) and in which any director, executive officer, holder of five percent or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.
Collaboration and Advisory Services
During the years ended December 31, 2021 and 2022, we made payments for advisory and related services from Be the Match BioTherapies Collection Services, LLC (f/k/a Be the Match BioTherapies, LLC) (“BTMB”) and its affiliates, including National Marrow Donor Program (“NMDP”) in the amount of $495,049 and $497,858, respectively. We were party to a collaboration agreement with NMDP (as successor in interest to BTMB) and a research agreement with an affiliated organization, Center for International Blood and Marrow Transplant Research during 2021 and 2022. Amy Lynn Ronneberg was formerly the president of BTMB, and she is the Chief Executive Officer of NMDP and a member of our Board of Directors. These fees were paid to BTMB and its affiliates pursuant to the collaboration agreement in amounts mutually agreed upon in advance by us and BTMB. None of these fees were paid directly to Ms. Ronneberg. The fees paid to BTMB did not exceed 5% of the consolidated gross revenue of BTMB (or NMDP) during fiscal years 2021 and 2022.
ImmunoGen
Dr. Michael Vasconcelles joined our Board of Directors on August 15, 2022, and he joined ImmunoGen as Executive Vice President of Research, Development, and Medical Affairs on December 29, 2022. During the years ended December 31, 2021 and 2022, we made payments of approximately $1.6 million and $4.5 million, respectively, to ImmunoGen pursuant to a license agreement. None of these fees were paid directly to Dr. Vasconcelles. The fees paid to ImmunoGen did not exceed 5% of the consolidated gross revenue of ImmunoGen during fiscal years 2022 and 2021.
Limitation of Liability and Indemnification of Officers and Directors
Our Certificate of Incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:
| • | any breach of their duty of loyalty to our company or our stockholders; |
| • | any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law; |
| • | unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or |
| • | any transaction from which they derived an improper personal benefit. |
Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.
In addition, our By-laws provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise. Our By-laws provide that we may indemnify to the fullest extent permitted by law any person who is or was a party or is threatened to be made a party to any action, suit, or proceeding by reason of the fact that he or she is or was one of our employees or agents or is or was serving at our request as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Our By-laws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final disposition of any action or proceeding, subject to very limited exceptions.
21
Table of Contents
We have entered into, and in the future plan to enter into, agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of our company or that person’s status as a member of our Board of Directors to the maximum extent allowed under Delaware law.
Related Person Transaction Policy
Our Board of Directors adopted a written related person transactions policy providing that transactions with our directors, officers and holders of five percent or more of our voting securities and their affiliates must be approved by our Audit Committee. This policy became effective on June 20, 2018. Pursuant to this policy, the Audit Committee has the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person is defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.
As appropriate for the circumstances, the Audit Committee will review and consider, among other factors that it deems appropriate, whether the related person transaction is on terms no less favorable to the Company than terms generally available in a transaction with an unaffiliated third-party under the same or similar circumstances and the extent of the related person’s interest in the related person transaction.
