Who Can Vote at the Annual Meeting?
Only stockholders of record at the close of business on the record date of April 1, 2024 are entitled to receive notice of the Annual Meeting and to vote the shares of our common stock that they held on that date. As of April 1, 2024, there were 68,308,405 shares of common stock issued and outstanding. Each share of common stock is entitled to one vote on each matter properly brought before the Annual Meeting. A list of registered stockholders as of the close of business on the record date will be available for examination by any stockholder for any purpose germane to the Annual Meeting for a period of at least 10 days prior to the Annual Meeting. If you wish to view this list, please contact our corporate secretary at Arvinas, Inc., 5 Science Park, 395 Winchester Ave., New Haven, CT 06511 Attention: Corporate Secretary.
Difference between a "stockholder of record" and a beneficial owner of shares held in "street name"
Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Computershare N.A., then you are considered a "stockholder of record" of those shares. In this case, your Notice has been sent to you directly by us. You may vote your shares by proxy prior to the Annual Meeting by following the instructions contained on such Notice.
Beneficial Owners of Shares Held in Street Name. If your shares are held by a bank, broker or other nominee, then you are considered the beneficial owner of those shares, which are held in "street name." In this case, your Notice has been forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to instruct that organization as to how to vote the shares held in your account by following the instructions contained on the voting instruction card provided to you by that organization.
How to Vote
If you are a stockholder of record, you can vote your shares in one of two ways: either by proxy prior to the Annual Meeting or online at the Annual Meeting. If you choose to vote by proxy, you may do so by telephone, via the Internet or by mail. Each of these methods is explained below. If you hold your shares of our common stock in multiple accounts, you should vote your shares as described in each set of proxy materials you receive.
•By Telephone.You may transmit your proxy voting instructions by calling 1-800-690-6903. You will need to have your Notice or proxy card in hand when you call.
•Via the Internet.You may transmit your proxy voting instructions via the Internet by accessing the website specified on the enclosed proxy card. You will need to have your Notice or proxy card in hand when you access the website.
•By Mail.If you received a printed copy of the proxy materials, you may vote by proxy by completing, signing and dating the proxy card provided to you and returning it in the prepaid envelope provided to you.
•At the Virtual Annual Meeting.The meeting will be held entirely online. To participate in the meeting, you will need the 16-digit control number included in your Notice or on the instructions that accompanied your proxy materials. The meeting webcast will begin promptly at 8:30 a.m. Eastern Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 8:15 a.m. Eastern Time, and you should allow ample time to test your computer and for the check-in procedures.
Telephone and Internet voting for stockholders of record will be available up until 11:59 p.m. Eastern Time on May 28, 2024, the day before the Annual Meeting, and mailed proxy cards must be received by May 28, 2024, the day before the Annual Meeting, in order to be counted at the Annual Meeting. If the Annual Meeting is adjourned or postponed, these deadlines may be extended. The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares held in "street name" will depend on the voting processes of the organization that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction card and any other materials that you receive from that organization.
Ballot Measures Considered "Discretionary" and "Non-Discretionary"
If your shares are held in "street name," your bank, broker or other nominee may under certain circumstances vote your shares if you do not return voting instructions. Banks, brokers or other nominees are permitted to vote customers' shares
3
Table of Contents
for which they have received no voting instructions on specified "discretionary" matters, but they are not permitted to vote these shares on "non-discretionary" matters.
The election of directors (Proposal No. 1) and the advisory vote on executive compensation (Proposal No. 2) are considered non-discretionary matters under applicable rules. Therefore, if your shares are held in "street name," your bank, broker or other nominee cannot vote on these matters without voting instructions from you. If you do not instruct your bank, broker or other nominee how to vote with respect to the election of directors (Proposal No. 1) and the advisory vote on executive compensation (Proposal No. 2), your bank, broker or other nominee may not vote with respect to these proposals and your shares will be counted as "broker non-votes."

The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2024 (Proposal No. 3) is considered a discretionary matter under applicable rules. Therefore, if your shares are held in "street name," we expect that your bank, broker or other nominee will be able to exercise discretionary authority to vote on the matter in the absence of voting instructions from you. If your bank, broker or other nominee exercises this discretionary authority, no broker non-votes are expected to occur in connection with Proposal No. 3.
Quorum
A quorum of stockholders is necessary to hold a valid meeting. Our second amended and restated bylaws, or our bylaws, provide that a quorum will exist if stockholders holding a majority of the shares of stock issued and outstanding and entitled to vote are present at the meeting "in person" virtually or represented by proxy. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.
For purposes of determining whether a quorum exists, we will count as present any shares that are voted over the Internet, by telephone, by completing and submitting a proxy by mail or that are represented virtually during the Annual Meeting. Further, for purposes of establishing a quorum, we will count as present shares that a stockholder holds even if the stockholder votes to abstain or only votes on one of the proposals. In addition, we will count as present shares that are "broker non-votes."
Votes Required
To be elected, a director nominee must receive a plurality of the votes cast by stockholders entitled to vote at the meeting (Proposal No. 1). Votes withheld and broker non-votes will not be counted as votes cast or voted on Proposal No. 1. Accordingly, votes withheld and broker non-votes will have no effect on the voting on Proposal No. 1.

For each of Proposal No. 2 (to approve, on an advisory basis, the compensation of our named executive officers) and Proposal No. 3 (to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2024), the affirmative vote of the holders of a majority of the shares of common stock present or represented by proxy and voting "for" or "against" such matter at the Annual Meeting is required for approval (meaning, the number of votes cast "for" each proposal must exceed the number of votes cast "against" each proposal). Abstentions and broker non-votes will not be counted as votes cast or voted on Proposal No. 2 or Proposal No. 3. Accordingly, abstentions and broker non-votes will have no effect on the voting on Proposal No. 2 or Proposal No. 3.
Method of Counting Votes
Each holder of common stock is entitled to one vote at the Annual Meeting on each matter to come before the Annual Meeting, including the election of directors, for each share held by such stockholder as of the record date. Votes cast online at the Annual Meeting or by proxy by mail, via the Internet or by telephone will be tabulated by the inspector of election appointed for the Annual Meeting, who will also determine whether a quorum is present.
Revoking a Proxy; Changing Your Vote
If you are a stockholder of record, you may revoke your proxy before the vote is taken at the meeting by:
•submitting a new proxy with a later date before the applicable deadline either signed and returned by mail or transmitted using the telephone or Internet voting procedures described in the "How to Vote" section above;
•voting online at the meeting, as described in the "How to Vote" section above; or
4
Table of Contents
•filing a written revocation with our corporate secretary.
If your shares are held in "street name," you may submit new voting instructions by contacting your bank, broker or other nominee holding your account. You may also vote online at the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions, if you obtain a legal proxy from the organization that holds your shares as described in the "How to Vote" section above.
Your virtual attendance at the Annual Meeting will not automatically revoke your proxy, unless you vote online during the Annual Meeting.
Costs of Proxy Solicitation
We will bear the costs of soliciting proxies. In addition to solicitations by mail, our directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, facsimile, email, personal interviews and other means.
Voting Results
We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

OVERVIEW OF PROPOSALS

This proxy statement contains three proposals requiring stockholder action. Proposal No. 1 requests the election of three Class III directors to the Board of Directors. Proposal No. 2 requests approval, on an advisory basis, of the compensation of our named executive officers. Proposal No. 3 requests the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024. All proposals are discussed in more detail in the pages that follow.

PROPOSAL NO. 1-ELECTION OF THREE CLASS III DIRECTORS
Our board of directors currently consists of ten members. In accordance with the terms of our restated certificate of incorporation and our bylaws, our board of directors is divided into three classes (Class I, Class II and Class III), with members of each class serving staggered three-year terms. The members of the classes are currently divided as follows:
•the Class I directors are Linda Bain, John Houston, Ph.D., and Laurie Smaldone Alsup, M.D., and their term expires at the annual meeting of stockholders to be held in 2025;
•the Class II directors are Sunil Agarwal, M.D., Leslie V. Norwalk, Esq., and John Young., to be held in 2026; and
•the Class III directors are Wendy Dixon, Ph.D., Edward Kennedy, Jr., Everett Cunningham, and Briggs Morrison, M.D., and their term expires at the Annual Meeting.
Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires.
Our restated certificate of incorporation and our bylaws provide that the authorized number of directors may be changed only by resolution of our board of directors. Our restated certificate of incorporation and bylaws also provide that our directors may be removed only for cause by the affirmative vote of the holders of at least 75% of the votes that all our stockholders would be entitled to cast in an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.
Our board of directors, based on the recommendation of the nominating and corporate governance committee of our board of directors, has nominated three current Class III members, Edward Kennedy, Jr., Everett Cunningham, and Briggs Morrison, M.D., for election as Class III directors at the Annual Meeting. Wendy Dixon, Ph.D.,will not be standing for re-election as a Class III director at the Annual Meeting. Following the Annual Meeting subject to approval of this proposal, our board of directors will consist of nine members. Each of the nominees has indicated a willingness to serve as director, if elected. We have no reason to believe that any of our nominees will be unable to serve. However, if a nominee becomes unable or unwilling to serve, the proxies may be voted for substitute nominees selected by our board of directors, or our board of directors may reduce the number of directors to be elected at the Annual Meeting
Our corporate governance guidelines provide that nominees should represent a diverse array of personal and professional characteristics, including gender, racial or ethnic identity, sexual identity, international experience and/or expertise in a particular discipline or field. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, the ability to contribute positively to the collaborative culture among our board members, knowledge of our business, understanding of the competitive landscape in which we operate and adherence to high ethical standards. Certain individual qualifications and skills of our directors that contribute to our board of directors' effectiveness as a whole are described in the following paragraphs.

CORPORATE GOVERNANCE
Director Nomination Process
Our nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board, and recommending the persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.
The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the nominating and corporate governance committee and our board. The qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:
•Nominees should have a reputation for integrity, honesty and adherence to high ethical standards.
•Nominees should have demonstrated business acumen, experience and ability to exercise sound judgments in matters that relate to our current and long-term objectives and should be willing and able to contribute positively to our decision-making process.
•Nominees should have a commitment to understand our company and our industry and to regularly attend and participate in meetings of our board of directors and its committees.
•Nominees should have the interest and ability to understand the sometimes conflicting interests of our various constituencies, which include stockholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of all stockholders.
•Nominees should not have, nor appear to have, a conflict of interest that would impair the nominee's ability to represent the interests of all of our stockholders and to fulfill the responsibilities of a director.
•The value of diversity on our board of directors is considered. Nominees should represent a diverse array of personal and professional characteristics, including gender, racial or ethnic identity, sexual identity, international experience and/or expertise in a particular discipline or field. Nominees will not be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law.
The nominating and corporate governance committee may use a third party search firm in those situations where particular qualifications are required or where existing contacts are not sufficient to identify an appropriate candidate. In any formal broad search for director candidates, the nominating and corporate governance committee shall be expected to include, and shall direct any search firm engaged for such purpose to include women and racially/ethnically diverse candidates in the initial pool from which candidates are selected. Mr. Cunningham was initially identified as a director candidate by a third party search firm.
At the Annual Meeting, stockholders will be asked to consider the election of Mr. Kennedy, Mr. Cunningham and Dr. Morrison. Mr. Cunningham was appointed to the board of directors in December 2022 and has been nominated for election as directors by our stockholders for the first time. Mr. Kennedy and Dr. Morrison are each standing for re-election by the stockholders at the Annual Meeting. They were each initially recommended by the nominating and corporate governance committee.
Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our corporate secretary at our principal executive offices and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. The specific requirements for the information that is required to be provided for such recommendations to be considered are specified in our bylaws and must be received by us no later than the date referenced below under the heading "Stockholder Proposals." Assuming that biographical and
13
Table of Contents
background material has been provided on a timely basis, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting.
Director Independence
Rule 5605 of the Nasdaq Listing Rules requires a majority of a listed company's board of directors to be comprised of independent directors within one year of listing. In addition, the Nasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company's audit, compensation and nominating and corporate governance committees be independent under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Audit committee members must also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under Rule 5605(a)(2), a director will only qualify as an "independent director" if, in the opinion of our board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director's ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by such company to the director; and whether the director is affiliated with the company or any of its subsidiaries or affiliates. In March 2024, our board of directors undertook a review of the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that each of Messrs. Cunningham, Kennedy and Young, Mss. Bain and Norwalk and Drs. Agarwal, Dixon, Morrison and Smaldone Alsup is an "independent director" as defined under Nasdaq Listing Rules. Our board of directors previously made a similar determination with respect to Dr. Shannon, who served as an independent member of our board of directors until June 2023. Dr. Houston is not an independent director under these rules because he is our President and Chief Executive Officer. Our board of directors has also determined that Ms. Bain, Mr. Cunningham and Ms. Norwalk, who comprise our audit committee, and Drs. Dixon and Smaldone Alsup and Mr. Young, who currently comprise our compensation committee, satisfy the independence standards for such committees established by the SEC and the Nasdaq Listing Rules, as applicable. In making such determination, our board of directors considered the relationships that each such non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director.
Board Committees
Our board of directors has established an audit committee, a compensation committee, a nominating and corporate governance committee and a science and technology committee. Each of the audit committee, compensation committee, nominating and corporate governance committee and science and technology committee operates under a charter, and each such committee reviews its respective charter at least annually. A current copy of the charter for each of the audit committee, compensation committee, and the nominating and corporate governance committee is posted on the corporate governance section of the Investors & Mediasection on our website, which is located at http://www.arvinas.com. Information contained on our website is not incorporated by reference in, or considered part of, this proxy statement.
Audit Committee
The members of our audit committee are currently Linda Bain, Everett Cunningham and Leslie V. Norwalk, Esq. Ms. Bain is the chair of our audit committee. Our board of directors has determined that each of Ms. Bain, Mr. Cunningham and Ms. Norwalk is independent within the meaning of Rule 10A-3 under the Exchange Act. Our board of directors has determined that Ms. Bain is an "audit committee financial expert" as defined in applicable SEC rules. Our board of directors believes that the composition of our audit committee meets the requirements for independence under current Nasdaq and SEC rules and regulations. Our audit committee assists our board of directors in its oversight of our accounting and financial reporting

process and the audits of our consolidated financial statements. The audit committee met nine times during the year ended December 31, 2023, including telephonic and videoconference meetings.
Our audit committee's responsibilities include:

All audit services to be provided to us and all non-audit services to be provided to us by our registered public accounting firm must be approved in advance by our audit committee. The report of the audit committee is included in this proxy statement under "Report of the Audit Committee."
Compensation Committee
The members of our compensation committee currently are Wendy Dixon, Ph.D., Laurie Smaldone Alsup, M.D., and John Young. Dr. Dixon is the currently chair of our compensation committee. Dr. Shannon served as a member of our compensation committee until our 2023 annual meeting of stockholders, as he did not stand for re-election. Our board of directors has determined that each of Drs. Smaldone Alsup and Dixon and Mr. Young is independent within the meaning of Rule 10C-1 under the Exchange Act. Dr. Dixon will not stand for re-election at the Annual Meeting. Following the Annual Meeting, we expect that our board of directors will reconstitute the compensation committee, such that the committee will comprise Laurie Smaldone Alsup, M.D., Everett Cunningham and John Young, with Mr. Young as the chair of the compensation committee. Our compensation committee assists our board of directors in the discharge of its responsibilities relating to the compensation of our executive officers. The compensation committee met five times during the year ended December 31, 2023, including telephonic and videoconference meetings.
Our compensation committee's responsibilities include:
•reviewing and approving, or making recommendations to our board of directors with respect to, the compensation of our chief executive officer and our other executive officers;
•overseeing an evaluation of our senior executives;
•overseeing and administering our cash and equity incentive plans;
•reviewing and making recommendations to our board of directors with respect to director compensation;
•overseeing the development, implementation and effectiveness of our policies and strategies relating to its human capital management function;
15
Table of Contents
•reviewing and discussing annually with management our "Compensation Discussion and Analysis" disclosure; and
•preparing the compensation committee report if and to the extent then required by SEC rules.
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. No officer may participate in, or be present during, any deliberations or determinations of the compensation committee regarding the compensation for such officer or any immediate family member of such officer. The charter of the compensation committee grants the compensation committee full access to all of our books, records, facilities, and personnel, as well as authority to obtain, at our expense, advice and assistance from internal and external legal, accounting, or other advisors and consultants, and other external resources that the compensation committee considers necessary or appropriate in the performance of its duties. In particular, the compensation committee may, in its sole discretion, retain 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.
The compensation committee engaged Aon's Human Capital Solutions Practice (formerly Radford) as its compensation consultant during 2023. Our compensation committee considered the relationship that Aon has with us, the members of our board of directors and our executive officers. Based on the committee's evaluation, the compensation committee has determined that no conflicts of interest exist between the company and Aon.
Aon assisted the committee in conducting a competitive compensation assessment for our executive officers for the fiscal year ended December 31, 2023. In evaluating the total compensation of our executive officers, the compensation committee, with the assistance of Aon, established a peer group of 17 publicly traded companies in the biopharmaceutical industry that comprised companies whose market capitalization, number of employees, maturity of product development pipeline and area of therapeutic focus are similar to ours.
Aon also supplemented the peer group information with published survey data, which provided a broader market representation of companies and deeper position reporting.
Historically, our compensation committee reviews all compensation components including base salary, bonus, benefits, equity incentives and, if any, perquisites, as well as severance arrangements, change-in-control benefits and other forms of executive officer compensation and provides a recommendation on the compensation of our Chief Executive Officer to our board of directors. In addition, 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 our compensation strategy, potential modifications to that strategy, and new trends, plans, or approaches to compensation, at various meetings throughout the year. The compensation committee also makes recommendations to our board of directors regarding the compensation of non-employee directors and has the authority to administer our equity-based plans.
Under its charter, the compensation committee may form, and delegate authority to, subcommittees, consisting of independent directors, as it deems appropriate. Pursuant to our 2018 Stock Incentive Plan, or our 2018 Plan, the compensation committee has delegated to our Chief Executive Officer the authority to approve grants of stock options and restricted stock units to new hire employees up to the level of Vice President, subject to certain limitations for each level of employment and an annual aggregate maximum amount of awards that can be granted pursuant to such delegated authority.

Compensation Committee Interlocks and Insider Participation
During 2023, in the period for which such person was a director, the members of our compensation committee were Laurie Smaldone Alsup, M.D., Wendy Dixon, Ph.D., Timothy Shannon, M.D., and John Young. None of our executive officers serves, or in the past has served, as a member of the board of directors or compensation committee (or other committee serving an equivalent function) of any entity that has one or more of its executive officers serving as a member of our board of directors or our compensation committee. None of the members of our compensation committee is currently an officer or employee of our company. Dr. Shannon previously served as our interim Chief Executive Officer from July 2013 to December 2014.

Director Attendance at Annual Meeting of Stockholders
Although we do not have a formal policy regarding attendance by members of our board of directors at our annual meeting of stockholders, we encourage all of our directors to attend. All of our then-serving directors attended our 2023 annual meeting of stockholders.
Code of Business Conduct and Ethics
We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the code is posted under the heading "Corporate Governance" on the Investors & Mediasection of our website, which is located at http://www.arvinas.com. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.
Corporate Governance Guidelines
Our board of directors has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of our company and our stockholders. The guidelines provide that:
•our board's principal responsibility is to oversee the management of our company;
•except as required by Nasdaq rules, a majority of the members of our board must be independent directors;
•the independent directors meet in executive session at least twice a year;
•directors have full and free access to management and, as necessary, independent advisors; and
•our nominating and corporate governance committee will oversee annual self-evaluations of the board to determine whether it and its committees are functioning effectively.
A copy of the corporate governance guidelines is posted under the heading "Corporate Governance" on the Investors & Mediasection of our website, which is located at http://www.arvinas.com.
Board Leadership Structure and Board's Role in Risk Oversight
Our corporate governance guidelines provide that the roles of chairperson of the board and chief executive officer may be separated or combined. Historically, the roles of chairperson of the board and chief executive officer have been separate. Separate chairperson and chief executive officer positions allowed our Chief Executive Officer, Dr. Houston, to focus on running the business, while allowing our chairperson of the board of directors, Dr. Shannon, to lead our board in its fundamental role of providing advice to and oversight of management. Our board of directors believes that its leadership structure was appropriate because it effectively balanced strategic development and independent leadership and management oversight in the board process.
Following the 2023 annual meeting of stockholders in June 2023, or the 2023 Annual Meeting, upon Dr. Shannon's cessation of tenure as chairperson and member of our board of directors, our board of directors has determined that the roles of chairperson of the board of directors and chief executive officer should be combined. As such, effective as of immediately following the 2023 Annual Meeting, Dr. Houston has served as Chairperson and Chief Executive Officer. In light of this combination of roles, to continue good governance practice and in line with our corporate governance guidelines, our board of directors appointed Briggs Morrison, M.D. as lead independent director, effective as of immediately following the 2023 Annual Meeting. As lead independent director, Dr. Morrison's duties include:
•acting as chairperson in executive sessions;
•meeting with any director not adequately performing duties;
•facilitating communications between our directors and the combined Chairperson and Chief Executive Officer, as appropriate;
•monitoring stockholder communications with the assistance of our legal department;
18
Table of Contents
•working with the Chairperson to prepare the agenda for meetings of our board of directors and determining whether special meetings are required; and
•otherwise consulting with the Chairperson and Chief Executive Officer on corporate governance and director performance matters.

Our board of directors believes that this board leadership structure is appropriate at this time given the following:
•Dr. Houston and Dr. Morrison have an excellent professional working relationship as demonstrated by their many years of working collaboratively; and
•Combining the roles of Chairperson and Chief Executive Officer fosters clear accountability, effective decision-making and alignment of corporate strategy, and facilitates information flow between management and our board of directors.

Our nominating and corporate governance committee and our board of directors evaluate our board leadership structure from time to time and may recommend further alterations of this structure.

Risk is inherent with every business and how well a business manages risk can ultimately determine its success. We face a number of risks, including those described under "Risk Factors" in our 2023 Annual Report. Our board of directors is actively involved in oversight of risks that could affect us. This oversight is conducted primarily by our full board of directors, which has responsibility for general oversight of risks. Our board of directors oversees our risk management processes directly and through its committees. Our management is responsible for risk management on a day-to-day basis and our board of directors and its committees oversee the risk management activities of management. Our board of directors satisfies this responsibility through full reports by each committee chair regarding the committee's considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within our company. Our audit committee oversees risk management activities related to financial controls and legal and compliance risks, including cybersecurity and financial risks, the steps that management has taken to monitor and control such exposure, and oversees the company's efforts to remediate any control deficiencies. Oversight by the audit committee includes direct communication with our independent registered public accounting firm. Our compensation committee oversees risk management activities relating to our compensation policies and practices and assessing whether any of our compensation policies or programs has the potential to encourage excessive risk taking. Oversight by the compensation committee includes direct communication with our independent compensation consultants. Our nominating and corporate governance committee oversees risk management activities relating to board composition and management succession planning. Our science and technology committee is designed to assist the board's oversight of our research and development activities. In addition, members of our senior management team attend our quarterly board meetings and are available to address any questions or concerns raised by the board on major risk exposures, the potential impact of such risks, risk management and any other matters. Our board of directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight.

Director Education
The Board also receives periodic briefings and education on core concepts and trends that impact our businesses and society.

Corporate Social Responsibility
We believe that we have a responsibility to foster a diverse, equitable and inclusive workplace environment and to have a positive impact on our employees and the communities in which we work and live. We believe our success largely depends on our ability to attract, motivate, engage, and retain highly skilled employees. We believe a diverse, equitable and inclusive culture encourages leadership growth and development and fosters robust relationships among employees and management, which, combined with providing competitive compensation and benefits, may create a workplace that results in more creative thinking, more rapid discovery and better decision making.

Equity and Belonging
Our employees are our strongest asset. As we continue to grow as an organization, we remain dedicated to cultivating a culture that respects the worth, dignity, and equality of every individual in our organization. We strive to ensure that our policies, processes, and programs are impartial, fair, and support equality for every individual in our organization. We
19

believe a feeling of belonging in our organization requires diversity and inclusion amongst all individuals, as well as actively enabling and encouraging all individuals to be visible, heard and engaged in our community.

Growth and Development
We recognize that identifying, attracting, incentivizing, integrating, retaining and promoting talented employees is vital to our success, particularly as we continue to grow. We aim to create an equitable, inclusive and empowering environment in which our employees can grow and advance their careers, with the overall goal of developing, expanding and retaining our workforce to support our current pipeline and future business goals. Our efforts to recruit and retain a diverse and passionate workforce include providing competitive compensation, including equity incentive compensation, and comprehensive benefits that provide resources to help employees manage their health, finances and life outside of work. As of December 31, 2023, and for the last several years, our company turnover rate was and has been lower than the industry market average.

Training and educating our employees is key to our organizational success. We endeavor to provide in person and virtual trainings, as well as experiential learning through cross-functional exposure via presentations or shadowing opportunities. In addition, we value our employees' opinions and thoughts and provide virtual and onsite forums where our employees can provide feedback on corporate initiatives, recognize each other's contributions and accomplishments, and provide other suggestions for improving our evolving workplace. We prioritize employee feedback, and conduct an employee survey to measure employee engagement and to inform future talent initiatives. Similarly, we have introduced technology that enables employees to provide anonymous real-time feedback.

We are also committed to diversity, equity and inclusion and we are committed to increasing representation of under-represented populations at our company, particularly in leadership roles. Over the last several years we have made conscious hiring decisions to significantly grow the number of women and diverse employees, particularly in positions of Director or above. In addition, as of December 31, 2023, four members of our board of directors identify as female and two members of our board of directors identify as racially diverse.

With the goal of ensuring every employee is included, supported, and treated equitably, certain of our employees formed a committee to support and guide us as a diverse, inclusive, and culturally intelligent workplace. This committee comprises a mix of employees from various functions and positions. Since its launch in 2021, the committee has worked to identify areas for growth and education in order to develop processes, systems and actions that will enable us to continue to build an inclusive workplace and a diverse workforce.

Compensation and Benefits
We offer a comprehensive compensation and benefits package, which includes a competitive salary, medical, dental, and vision insurance, medical and dependent flexible spending accounts, life and disability insurance, and a 401(k) matching program. In addition, employees typically receive equity in the company upon the start of their employment and on an annual basis, and also have the opportunity to participate in our employee stock purchase plan. To ensure that our employees are paid competitively and at a rate consistent with an employee's position, knowledge and skills, we perform a formal compensation benchmark analysis of our employees' base salary, annual cash incentive potential, and long-term incentive awards twice per year and link annual cash incentives to overall company performance.

We also have a tuition reimbursement program, fitness reimbursement program, and various programs that focus on our employee's engagement and well-being, including access to our employee assistance program and company supported, employee-led clubs and teams.

Our Community
We believe in the importance of our employees engaging in our community. In 2023, we hosted our second annual IMPACT day, a company-wide community service day benefiting organizations in the Greater New Haven area. Giving back to the communities in which we work and live is an integral part of our corporate values and over half of our employees participated in person or virtually. The activities selected support important priorities for Arvinas, including science, technology, engineering, and math (STEM) initiatives, and the Greater New Haven and patient communities.

PROPOSAL NO. 2-ADVISORY VOTE ON EXECUTIVE COMPENSATION
We are providing our stockholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our executive officers named in the "2023 Summary Compensation Table" under "Executive and Director Compensation," who we refer to as our "named executive officers," as disclosed in this proxy statement in accordance with the SEC's rules. This proposal, which is commonly referred to as "say-on-pay," is required by Section 14A to the Exchange Act.
Our executive compensation programs are designed to attract, motivate, and retain our executive officers, who are critical to our success. Under these programs, our named executive officers are rewarded for the achievement of key strategic and business goals. The programs are designed to align the interests of our executives with those of our stockholders and consist of a combination of base salary, annual cash bonus, long-term equity incentive compensation and other employee benefits generally available to our employees.
The "Executive and Director Compensation" section of this proxy statement beginning on page 23, including "Compensation Discussion and Analysis," describes in detail our executive compensation programs and the decisions made by the compensation committee and our board of directors with respect to the year ended December 31, 2023.
As we describe in the Compensation Discussion and Analysis, our executive compensation program embodies a pay-for-performance philosophy that supports our business strategy and aligns the interests of our executives with our stockholders. Our board of directors believes this link between compensation and the achievement of our key strategic and business goals has helped drive our performance over time. At the same time, we believe our program does not encourage excessive risk-taking by management.
Our board of directors is asking stockholders to approve a non-binding advisory vote on the following resolution:
RESOLVED, that the compensation paid to the company's named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and any related material disclosed in this proxy statement, is hereby approved.

As an advisory vote, this proposal is non-binding. The outcome of this advisory vote does not overrule any decision by the company or our board of directors (or any committee thereof), create or imply any change to the fiduciary duties of the company or our board of directors (or any committee thereof), or create or imply any additional fiduciary duties for the company or our board of directors (or any committee thereof). However, our compensation committee and board of directors value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for named executive officers. Consistent with the preference expressed by our stockholders at our 2021 annual meeting of stockholders, our board of directors has adopted a policy of providing annual advisory votes to approve the compensation of our named executive officers. The next advisory vote to approve the compensation of our named executive officers will occur at our 2025 annual meeting of stockholders.
The board of directors recommends voting "FOR" Proposal No. 2 to approve our executive compensation.

Any properly submitted proxy will be voted in favor of the approval of our executive compensation unless a contrary specification is made in the proxy.

EXECUTIVE AND DIRECTOR COMPENSATION
Compensation Discussion and Analysis
This section discusses the material elements of our executive compensation policies and decisions for our executive officers named in the "2023 Summary Compensation Table" below, referred to herein as our "named executive officers," and important factors relevant to an analysis of these policies and decisions. It provides qualitative information regarding the manner and context in which compensation is awarded to and earned by our named executive officers and is intended to place in perspective the information presented in the following tables and the corresponding narrative.
Executive Summary
Overview
Historically, our executive compensation program has reflected our growth and corporate goals. To date, the compensation of our named executive officers has consisted of a combination of base salary, annual cash bonus, long-term equity incentive compensation, and other employee benefits generally available to our employees. Our named executive officers are also entitled to certain compensation and benefits upon certain terminations of employment pursuant to their employment agreements as described below.
Our named executive officers for the year ended December 31, 2023 are as follows:
•John Houston, Ph.D., President and Chief Executive Officer;
•Sean Cassidy, former Chief Financial Officer;
•Ronald Peck, M.D., former Chief Medical Officer; and
•Ian Taylor, Ph.D., Chief Scientific Officer.

We note that because we only had four executive officers during our fiscal year ended December 31, 2023, we only have four named executive officers.

Our Company

We are a clinical-stage biopharmaceutical company dedicated to improving the lives of patients suffering from debilitating and life-threatening diseases through the discovery, development, and commercialization of therapies that degrade disease-causing proteins. We use our proprietary PROTAC® Discovery Engine to engineer proteolysis targeting chimeras, or PROTAC® targeted protein degraders, which are designed to harness the body's own natural protein disposal system to selectively and efficiently degrade and remove disease-causing proteins. In addition to our robust preclinical pipeline of PROTAC® protein degraders against validated and "undruggable" targets, we have four investigational clinical-stage programs: vepdegestrant (ARV-471) for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer; bavdegalutamide (ARV-110) and ARV-766, each for the treatment of men with metastatic castrate-resistant prostate cancer; and ARV-102 for the treatment of patients with neurodegenerative disorders.
Key Compensation Decisions and Action Regarding 2023 Executive Compensation
Our board of directors and compensation committee made several key compensation decisions regarding the 2023 compensation of our executives taking into account our compensation philosophy and objectives, the needs and performance of our company, individual performance, and other factors such as market data and industry best practices.
•Base Salary Adjustments.The board of directors, upon recommendation by the compensation committee, reviewed and approved the base salary of our Chief Executive Officer and the compensation committee reviewed and approved the base salaries of our other named executive officers in February 2023. Our Chief Executive Officer and each of our other named executive officers received annual merit-based salary adjustments of 4% reflecting their performance and contributions and to maintain reasonable positioning relative to our peer companies.
•Annual Cash Bonus.In February 2023, the board of directors, upon recommendation by the compensation committee, approved corporate goals, consisting of three main corporate goals focused on clinical-stage development, preclinical pipeline and platform, and strategic and
23
Table of Contents
business development, each with certain subgoals and with its own weighting to reflect its importance to our business. In December 2023, the board of directors reviewed our achievements against our 2023corporate goals and approved achievement of 125% of our 2023 corporate goals. However, as part of our overall commitment to our employees, we funded a special bonus pool of 5% from the overall bonus pool of 125%. As such, the bonuses awarded to all employees, including our named executive officers, for 2023 were based on a corporate goal achievement level of 120.0%, and a portion of our employee population that contributed significantly to the company in 2023received additional bonus amount. The annual cash bonuses paid to our named executive officers in early 2024 for 2023performance were based solely on the achievement of these corporate performance goals and each named executive officer's target bonus amount, which remained unchanged year over year.
•Long-Term Incentives.In February 2023, the board of directors, upon recommendation by the compensation committee, approved annual grants of stock options and restricted stock units, or RSUs, under the 2018 Plan to our Chief Executive Officer, and the compensation committee approved grants of stock options and RSUs under the 2018 Plan to our other named executive officers.
Compensation Design
Compensation Philosophy and Objectives
The goal of our executive compensation policies and programs is to pay for performance. Within this overarching principle, there are a number of key objectives that our policies and programs are designed to achieve:
•Attract and retain individuals with superior ability, technical, and managerial experience;
•Align the executives' interests with those of our stockholders through long-term incentives linked to specific performance; and
•Provide market competitive compensation to attract and retain highly qualified individuals who are capable of making significant contributions to the long-term success of the company.
Alignment with Company Strategy
Our executive compensation policies and programs reinforce our pay-for-performance philosophy. While fixed compensation, such as base salary and benefits, are primarily designed to be competitive in the biopharmaceutical marketplace for employees, a substantial portion of our named executive officers' compensation is linked to achieving scientific, business, organizational and operational goals.
We provide a significant portion of our executive compensation in the form of long-term incentives (stock options and RSUs) that vest over time. These equity awards are a key aspect of our pay-for-performance philosophy and serve to align the interests of our named executive officers with our stockholders, as they are tied to future increases in the value of our stock. Further, we believe that equity awards with a time-based vesting feature promote retention because this feature incentivizes our named executive officers to remain in our employment during the vesting period. The annual cash bonuses paid to our named executive officers are based entirely on corporate performance goals established by the board of directors. Our executives make strategic decisions that influence the company, and we believe it is appropriate to reward performance against corporate performance goals in that case, in line with our pay-for-performance philosophy.

Table of Contents
The total target compensation (base salary, target annual cash bonuses and equity incentive awards) for our Chief Executive Officer and our other named executive officers in 2023 was primarily performance-based, as shown in the charts below:


The compensation committee uses a comparative framework to assess the named executive officers' total compensation mix, but does not have a pre-established policy for allocating total compensation. Rather, based on blended peer group and broader market data, market competitiveness, expected future contribution, experience, impact and individual performance, and internal parity relative to similar positions within the company, the compensation committee subjectively determines the appropriate level and mix of total compensation, keeping in mind our pay-for-performance compensation philosophy. We believe that this approach results in compensation that:
•is at an appropriate level to attract and retain individuals with superior ability, technical, and managerial experience;
•provides the appropriate incentives to our executives to make significant contributions to the long-term success of the company, while avoiding incentives for inappropriate risk-taking; and
•is fair and competitive without being excessive.

2023 Compensation Decisions and Outcomes
Role of our Compensation Committee and Executive Officers

Our compensation committee, composed entirely of independent directors, is responsible for overseeing our compensation philosophy and operates under a written charter. Among other things, the role of our compensation committee is to seek to ensure that compensation decisions represent sound fiscal policy and enable us to attract and motivate qualified personnel, review and approve, or make recommendations to our board of directors with respect to, the compensation of our Chief Executive Officer and our other executive officers and recommend to the board of directors the compensation of the board of directors.
In making its executive compensation determinations, our compensation committee and, if applicable, the full board of directors, considers recommendations from our Chief Executive Officer for our named executive officers (other than himself). In making his recommendations, our Chief Executive Officer has access to various third-party compensation surveys and compensation data provided by our compensation committee's compensation consultant, as described below. While our Chief Executive Officer discusses his recommendations for the other named executive officers with our compensation committee, he does not participate in the deliberations concerning, or the determination of, his own compensation. From time to time, various other members of management and other employees as well as outside advisors or consultants may be invited by our compensation committee to make presentations, provide financial or other background information or advice or otherwise participate in compensation committee meetings. No named executive officer is present during voting or deliberations on his own compensation.

Say-on-Pay Advisory Vote and Stockholder Engagement

Each year, pursuant to Section 14(a) of the Exchange Act, we submit to our stockholders a proposal to vote, on an advisory, non-binding basis, to approve the compensation of our named executive officers disclosed in our proxy statement. We first held this vote at the 2021 annual meeting of stockholders. In addition, at our 2021 annual meeting of stockholders, our stockholders voted that we hold such a vote every year.
26
Table of Contents

In setting executive compensation, the compensation committee and the board of directors also consider the results of this "say-on-pay" vote. At the 2023 annual meeting of stockholders, this proposal received over 83% of the votes cast by stockholders, excluding broker non-votes and abstentions. While the say-on-pay vote is an advisory, non-binding, vote, we strongly value the opinions of our stockholders as expressed by the results of the say-on-pay vote and believe that stockholder approval of our named executive officer compensation demonstrates an alignment with our stockholders' interests.

Our compensation committee and board will continue to consider stockholder input and monitor our executive compensation program to ensure it aligns the interests of our named executive officers with the interests of our stockholders and adequately addresses any stockholder concerns that may be expressed in future votes. Consistent with the recommendation of our board and the preference of our stockholders as reflected in the non-binding advisory vote on the frequency of future "say-on-pay" votes conducted at our 2021 annual meeting of stockholders, our stockholders will have an opportunity annually to cast an advisory vote in connection with compensation for our named executive officers.
Role of our Compensation Consultant
As a part of reviewing, recommending and determining (as applicable) compensation for our named executive officers, the compensation committee has engaged Aon's Human Capital Solutions Practice, a division of Aon plc ("Aon"), as an independent compensation consultant. Aonprovides analysis and recommendations to the compensation committee regarding:
•trends and emerging topics with respect to executive compensation;
•peer group selection for executive compensation benchmarking;
•compensation practices of our peer group;
•compensation programs for executives, directors and all of our employees; and
•stock utilization and related metrics.
When requested, Aonconsultants attend meetings of the compensation committee, including executive sessions in which executive compensation issues are discussed. Aonis engaged by the compensation committee and meets with management for purposes of gathering information for its analyses and recommendations.
In determining to engage Aon, the compensation committee reviewed the independence of Aontaking into consideration relevant factors, including the absence of other services provided to the company by Aon, the amount of fees the company paid to Aonas a percentage of Aon's total revenue, the policies and procedures of Aonthat are designed to prevent conflicts of interest, any business or personal relationship of the individual compensation advisors employed by Aonwith an executive officer of the company, any business or personal relationship the individual compensation advisors employed by Aon have with any member of the compensation committee, and any stock of the company owned by Aonor the individual compensation advisors employed by Aon. The compensation committee has determined, based on its analysis in light of all relevant factors, including the factors listed above, that the work of Aonand the individual compensation advisors employed by Aonas compensation consultants to the compensation committee has not created any conflicts of interest, and that Aonis independent pursuant to the independence standards set forth in The Nasdaq Global Select Market listing standards promulgated pursuant to Section 10C of the Exchange Act.
Executive Compensation Process
The compensation committee compares our executive compensation against a peer group to determine market trends and competitiveness. On an annual basis, the compensation committee reviews the companies in our peer group, as well as Aon's recommendations regarding which companies should be included in the peer group. The compensation committee may also adjust the peer group to ensure it properly reflects the market in which we compete for executive talent.

Table of Contents
For purposes of compensation for 2023,the compensation committee retained Aonto evaluate our executive compensation program and recommend a course of action for 2023. In determining the 2023 base salaries, annual cash bonuses and long-term incentives for our named executive officers, our compensation committee relied on the following peer group, or the 2023 Peer Group:
Alector, Inc.
Intellia Therapeutics, Inc. REGENXBIO, Inc.
Arcus Biosciences, Inc.
Intra-Cellular Therapies, Inc. Relay Therapeutics, Inc.*
Arrowhead Pharmaceuticals, Inc.*
Karuna Therapeutics, Inc.* Revolution Medicines, Inc.
Cerevel Therapeutics, Inc. Legend Biotech, Inc. SpringWorks Therapeutics, Inc.*
Denali Pharmaceuticals, Inc.
Mirati Therapeutics, Inc. Xencor, Inc.
Fate Therapeutics, Inc. Reata Pharmaceuticals, Inc.
* New to the 2023Peer Group
Aonfocused on developing a peer group that:
•comprised companies operating in the biopharmaceutical industries;
•captured comparable companies in terms of market capitalization, revenue, employee size and stage of development; and
•allowed for sufficient room for the company to grow.
The 2023 Peer Group represents a group of pre-commercial, later stage, oncology or neurology-focused biopharmaceutical/biotechnology companies,with a median market capitalization of $3,110.7 million and a median of 346 employees. Dicerna Pharmaceuticals, Inc., Rubius Therapeutics, Inc., Turning Point Therapeutics, Inc. and Zymeworks, Inc. were each removed from our peer group as their market capitalization and/or stage of development, as applicable, fell outside our targeted range, or due to acquisition, as applicable.
Based on the 2023 Peer Group, Aonprepared an assessment that included pay levels and compensation practices from public SEC filings. Aon supplemented the 2023 Peer Group proxy information with data from the Radford Global Compensation Survey, comprising 71 companies with a median headcount of 348 and a median market capitalization of $2.4 billion, which provides a broader market representation of companies and deeper position reporting. To arrive at competitive market compensation, market data collected from the 2023 Peer Group and the Radford Global Compensation Survey was blended equally to form a composite assessment.
In analyzing and setting our executive compensation program for 2023, the board of directors and the compensation committee, as applicable, compared certain aspects of our named executive officers' compensation to the compensation levels included in this composite assessment. Based on the results of the assessment, the board of directors and the compensation committee, as applicable, determined that compensation levels for our named executive officers in 2023 generally reflected market competitive ranges.
Base Salaries
The base salary for our Chief Executive Officer is determined annually by the board of directors, upon recommendation by the compensation committee. Base salaries for our named executive officers other than our Chief Executive Officer are recommended by our Chief Executive Officer to the compensation committee for approval. Each such determination is based on the scope of each officer's responsibilities along with his respective experience and contributions to the company during the prior year. When reviewing base salaries, the board of directors and compensation committee, as applicable, takes factors into account such as blended peer group and broader market data, market competitiveness, expected future contribution, experience, impact and individual performance, and internal parity relative to similar positions within the company, but does not assign any specific weighting to any factor.

Annual Cash Bonuses
Our annual cash incentive program promotes and rewards our executive officers for the achievement of key business and strategic goals. Under this program, cash incentive awards are determined by multiplying each executive officer's annualized base salary by a target annual bonus percentage and a corporate performance achievement factor established by our board of directors and compensation committee based on our performance as measured against our pre-established corporate goals. For the year ended December 31, 2023, the target annual bonus percentage was 60% for Dr. Houston and 45% for each of Mr. Cassidy, Dr. Peck and Dr. Taylor. Our board of directors and compensation committee, as applicable, set these targets at the beginning of the year and determined that annual cash bonus opportunities were competitive with the market based primarily on data provided by Aon.
During and following the last quarter of each year, our senior management team evaluates our company performance. Based on this evaluation, our Chief Executive Officer recommends to our compensation committee any cash awards for executives (other than himself) under our annual cash incentive program. Our compensation committee then carefully reviews overall corporate performance. Our board of directors, upon the recommendation of our compensation committee, then further reviews our Chief Executive Officer's compensation and evaluates our Chief Executive Officer's contributions to our corporate performance. Our board of directors and compensation committee, as applicable, have the discretion to adjust the size of individual awards upward or downward based on company performance.
At the beginning of 2023, the compensation committee and the board of directors established the corporate goals listed in the table below for the calendar year 2023, each overall goal having a designated weighting and relating to key development, strategic and business goals for the company. Our Chief Executive Officer and certain other members of senior management report to the compensation committee and the board of directors on our overall performance against these goals on a regular basis throughout the year. In addition, our compensation committee met with our Chief Executive Officer and certain other members of senior management as part of its annual compensation review and discussed our corporate performance in 2023 and a proposed corporate goal achievement score based on the Company's actual performance as calculated against the previously-established corporate goals. TheChief Executive Officer then proposed recommendations for cash incentive awards for each of our executive officers other than the Chief Executive Officer. Our board of directors then further evaluated the cash incentive award for our Chief Executive Officer. Because our overall corporate goals allow for some amount of subjective and qualitative assessment, the compensation committee and the board of directors engaged in a number of discussions, including with certain members of senior management, as to the appropriate scoring of the Company's performance against the goals previously-established corporate goals.

As part of its evaluation of our corporate performance, our compensation committee and our board of directors noted various performance outcomes, including certain upside considerations supporting actual level of achievement over 100%, during 2023, including the factors listed below.
Based on our overall performance during 2023 against these goals, our compensation committee and our board of directors determined that our overall corporate goals had been achieved at a level of 125%. However, as part of our overall commitment to our employees, we funded a special bonus pool of 5% from the overall bonus pool of 125%. As such, the bonuses awarded to all employees, including our named executive officers, for 2023 are based on a corporate goal achievement level of 120% and a portion of our employee population that contributed significantly to the company in 2023 received additional bonus amount. For the avoidance of doubt, for purposes of calculating annual bonuses for our named executive officers, bonuses were based on achievement of corporate goals at a level of 120%.

Long-term Incentives
Our equity awards program is designed to:
•reward demonstrated leadership and performance;
•align our executive officers' interests with those of our stockholders;
•retain our executive officers at least through the term of the awards;
•maintain competitive levels of executive compensation; and
•motivate our executive officers for outstanding future performance.
The market for qualified and talented executives in the biopharmaceutical industry is highly competitive and we compete for talent with many companies that have greater resources than we do. Accordingly, we believe equity compensation is a crucial component of any competitive executive compensation package we offer.
Historically, our equity awards have generally taken the form of stock options. In February 2023, our compensation committee determined that, in 2023 our annual equity incentive awards granted to our named executive officers would be in the form of stock options and RSUs, with two thirds of such award in the form of stock options and one third in the form of RSUs. We typically make equity award grants to each of our executive officers upon commencement of employment, annually in conjunction with our review of executive compensation, in connection with a promotion, or as a special incentive.
All equity awards to our executive officers are approved by our compensation committee and, other than equity awards to new hires, are typically granted by our compensation committee in the first quarter of the year. The size of equity awards varies among our executive officers based on their positions and annual performance assessments. All stock options granted to our executive officers have exercise prices equal to the fair market value of our common stock on the date of grant, so that the recipient will not realize any value from his options unless our share price increases above the exercise price on the date of grant. Accordingly, this portion of our executive officers' compensation is at risk and is directly aligned with stockholder value creation.
In addition, equity grants to our executive officers typically vest over four years, which we believe provides an incentive to our executives to add value over the long-term and to remain with our company. Typically, the stock options we grant to our executives have a ten-year term and vest as to 25% of the shares on the first anniversary of their grant date and then in equal monthly installments thereafter until the fourth anniversary of such date, and RSU awards we grant to our executives vest as to 25% of the shares on the first anniversary of their grant and then in equal annual installments thereafter until the fourth anniversary of such date. Vesting of equity granted to employees ceases upon termination of employment and exercise rights typically cease three months following termination of employment, except in the case of death or disability, for grants made under our 2018 Plan. Prior to the exercise of an option, or settlement of an RSU, the stock option or RSU holder, as applicable, does not have any rights as a stockholder with respect to the shares subject to such option or RSU, as applicable, including voting rights or the right to receive dividends or dividend equivalents. The compensation committee may approve different award types in the future as part of the overall compensation strategy. Awards made in connection with a new, extended or expanded employment relationship may involve a different mix of equity awards, depending on the compensation committee's assessment of the total compensation package being offered.

Table of Contents
In connection with the annual review of each executive officer's individual performance and consistent with our compensation philosophy, based on a long-term incentive value in line with our 30-day stock price and Black Scholes percentage, in February 2023, our compensation committee approved annual equity incentive awards for our named executive officers. The number of stock options awarded and RSUs to each named executive officer was based on the 30-day average stock price of our common stock on the Nasdaq Global Select Market as of January 6, 2023, which was of $35.00, and Black Scholes percentage of 67.5% of face value. The exercise price for each of these stock options was $34.37, which was equal to the closing price of our common stock on the Nasdaq Global Select Market on the date of grant. The annual equity incentive awards granted to our named executive officers are set forth in the table below:

Ian Taylor, Ph.D. 57,450 19,125
Other Benefits
Other compensation to our executives consists primarily of the broad-based benefits we provide to all full-time employees in the United States, including medical, dental and vision insurance, health spending accounts, short and long-term disability, accidental death and dismemberment, and life insurance, an employee stock purchase plan and a 401(k) plan. Pursuant to our 2018 employee stock purchase plan, or 2018 ESPP, employees, including our named executive officers, have an opportunity to purchase our common stock at a discount on a tax-qualified basis through payroll deductions. The 2018 ESPP is designed to qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code. The purpose of the 2018 ESPP is to encourage our employees, including our named executive officers, to become our stockholders and better align their interests with those of our other stockholders. We make discretionary matching contributions and other employer contributions on behalf of eligible employees under our 401(k) plan. For fiscal year 2023, we matched a portion of eligible employee contributions equal to 100% of the first 4% of eligible contributions pursuant to our 401(k) plan's matching formula.
Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites to our named executive officers, except in situations where we believe it is appropriate to assist an individual in the performance of his duties, to make him more efficient and effective, and for recruitment and retention purposes. None of our named executive officers received perquisites or other personal benefits with an aggregate value of $10,000 or more in 2023. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by our compensation committee.
Tax and Accounting Considerations
While our compensation committee generally considers the tax and accounting implications of its executive compensation decisions, neither element was a material consideration in the compensation awarded to our named executive officers in 2023.
Compensation Practices and Risk
As part of its responsibilities, the compensation committee reviews the impact of our executive compensation program and the associated incentives to determine whether they present a significant risk to us. The compensation committee has concluded, based on its reviews and analysis of our compensation policies and procedures, that such policies and procedures are not reasonably likely to have a material adverse effect on us. In making this determination, our compensation committee considered the following:
•our use of different types of compensation vehicles provides a balance of long-term and short-term incentives with fixed and variable components;
•our grant of equity-based awards with time-based vesting, which encourage our named executive officers to look to long-term appreciation in equity values;
33
Table of Contents
•our annual bonus determinations for each employee are dependent on the achievement of company goals, which we believe promote long-term value;
•our compensation committee's ability to exercise discretion in determining cash bonus payouts and long-term incentive awards for executive officers other than the Chief Executive Officer;
•our system of internal control over financial reporting and Code of Conduct, among other things, reduce the likelihood of manipulation of our financial performance to enhance payments under any of our incentive plans; and
•our prohibition on hedging or pledging of company stock.
Overview of Our Other Policies and Practices
Highlighted policies and practices that we use to ensure effective governance of compensation plans and decisions include:
•our compensation committee has the authority to hire independent counsel and other advisors;
•our compensation committee conducts a regular review and assessment of risk as it relates to our compensation policies and practices;
•as part of our Insider Trading Policy, our executive officers are prohibited from engaging in any hedging transactions of our common stock, including using prepaid variable forward contracts, equity swaps, collars, and exchange funds, or from pledging our common stock;
•we have no perquisites other than broad-based health, relocation, 401(k) plan and insurance-related benefits that we make available to all of our employees;
•our 2018 Plan prohibits option repricing (absent stockholder approval) and option backdating;
•our employment agreements do not provide for tax gross-ups;
•all of our non-employee directors are independent, including all members of our compensation committee; and
•if we are required to restate our financial results due to our material noncompliance with any financial reporting requirements under the applicable securities laws as a result of misconduct, our Chief Executive Officer and Chief Financial Officer may be legally required to reimburse us for any bonus or other incentive-based or equity-based compensation they receive in accordance with the provisions of section 304 of the Sarbanes-Oxley Act of 2002.

We have adopted a Dodd-Frank Compensation Recovery Policy, or Clawback Policy, in accordance with Rule 10D-1 of the Exchange Act and Nasdaq listing standards, which is applicable to all of our current or former executive officers, or the Covered Persons. The Clawback Policy is administered and interpreted by our compensation committee. In the event we are required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under U.S. federal securities laws, including any required restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, it is our policy to attempt to recover reasonably promptly the amount of erroneously awarded incentive-based compensation received by Covered Persons. The recovery of such compensation applies regardless of whether an executive engaged in misconduct or otherwise caused or contributed to the requirement for the accounting restatement. This policy is filed as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2023.

Compensation Committee Report
The compensation committee has reviewed and discussed the disclosure included in the Compensation Discussion and Analysis section of this Proxy Statement with management. Based on this review and discussion, the compensation committee recommended to the board of directors that the disclosure in the Compensation Discussion and Analysis section be included in this Proxy Statement for the year ended December 31, 2023.
Respectfully submitted by the compensation committee,
Wendy Dixon, Ph.D., Chairperson
John Young
Laurie Smaldone Alsup, M.D.
Pay Ratio
As required by the Dodd-Frank Act and SEC rules, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of John Houston, our President and Chief Executive Officer.
For 2023, we estimate the pay ratio of the annual total compensation of our President and Chief Executive Officer ($7,627,032 as reported in the 2023 Summary Compensation Table above) to the annual total compensation of our median employee ($266,130) to be approximately 29 to 1. We believe this ratio represents a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

There have been no changes in our employee population or employee compensation arrangements that we believe would significantly impact the calculations of this pay ratio and require us to identify a new median employee. Last year's reported median employee had anomalous compensation, therefore, consistent with SEC rules, for 2023, we chose to use a substitute employee that was identified near the median and who was viewed as more representative.

In 2022, the median employee was identified by examining our total employee population at October 15, 2022 of approximately 400 full-time employees, excluding our President and Chief Executive Officer. We then used base salary, incentive compensation (including annual cash bonuses and long-term incentives) and other incentive payments, as applicable, to determine the annual total compensation of our median employee. We did not make any cost-of-living or other adjustments.

The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay
42
Table of Contents
ratio reported by other companies may not be comparable to the pay ratio reported above as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Pay Versus Performance Disclosure

In accordance with rules adopted by the U.S. Securities and Exchange Commission pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosure regarding executive compensation for our principal executive officer, or PEO, and non-PEO named executive officers, or Non-PEO NEOs, and our performance for the fiscal years listed below. We did not use any financial performance measures to link Compensation Actually Paid to our performance in 2023. Therefore, this disclosure presents neither a Tabular List of most important financial performance measures nor a Company-Selected Measure. Further, The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

Stock Option and Other Compensation Plans

The three equity incentive plans described in this section are our Incentive Share Plan, our 2018 Plan and our 2018 ESPP. Prior to our IPO, we granted awards to eligible participants under our Incentive Share Plan. Following the closing of our IPO, we have granted awards to eligible participants under the 2018 Plan. We have also made inducement awards to certain new hires, which awards were not approved by our stockholders.
Securities Authorized for Issuance under Equity Compensation Plans
The following table contains information about our equity compensation plans as of December 31, 2023. As of December 31, 2023, we had three equity compensation plans: our Incentive Share Plan, our 2018 Plan and our 2018 ESPP, each of which was approved by our stockholders.

(2)Consists of our Incentive Share Plan, as amended to date, the 2018 Plan, and the 2018 ESPP. The amounts disclosed do not reflect an additional 2,721,117 shares of common stock authorized for issuance under the 2018 Plan as of January 1, 2024 and an additional 680,279 shares of common stock authorized for issuance under the 2018 ESPP as of January 1, 2024, in each case in accordance with the terms of the applicable plan. The 2018 Plan provides for further annual increases, to be added as of the first day of each fiscal year until, and including, January 1, 2028, equal to the lesser of 4,989,593 shares of our common stock, 4% of the number of shares of our common stock outstanding on such first day of the fiscal year in question or an amount determined by our board of directors. The 2018 ESPP provides for further annual increases, to be added as of the first day of each fiscal year until, and including, January 1, 2029, in an amount equal to the lesser of 1,247,398 shares of our common stock, 1% of the total number of shares of our common stock outstanding on the first day of the applicable year, or an amount determined by our board of directors.
Incentive Share Plan
The Incentive Share Plan, which became effective as of January 1, 2015 and which our board of directors amended on October 16, 2015, December 22, 2016, September 8, 2017 and March 29, 2018 (and which, as amended, we refer to as the Incentive Plan) provided for the grant of incentive units to our managers, directors, officers, employees, advisors and consultants, those of our majority-owned subsidiaries and those of any other entity which was designated by us from time to time as a participating employer under the Incentive Plan. Subject to adjustment, a maximum aggregate of 6,199,476 incentive units were authorized for issuance under the Incentive Plan. Incentive unit awards were governed by the terms of the Incentive Plan, the terms of the award agreement documenting the grant and the limited liability company agreement of Arvinas Holding Company, LLC, or the LLC Agreement, and were intended to qualify as "profits interests" within the meaning of Revenue Procedure 93-27 as clarified by Revenue Procedures 2001-43. The Incentive Plan terminated upon our conversion from an LLC to a corporation in 2018.
46
Table of Contents
Incentive units granted to eligible recipients generally were to vest, except as otherwise approved by our board of directors, over a period of four years, with 25% vesting following 12 months of continued employment or service and the balance vesting in equal monthly installments over the remaining three-year period, provided the holder continued to be employed by, or provide services to, us (or a related entity) on the applicable vesting date. Our board of directors may accelerate the vesting of any incentive units granted under the Incentive Plan at such times and upon such terms and conditions as the board of directors may deem advisable, which determination is made on an individual by individual basis. The Incentive Plan provided that in the event we sold outstanding equity securities in our subsidiaries and received cash proceeds in excess of a certain threshold amount, the incentive units would vest in full. In addition, any unvested incentive units held by a recipient would vest in full if his or her continuous service to us, or any related entity, was terminated without cause, as determined by our board of directors, within 12 months of a sale transaction (as that term is defined in the LLC Agreement).
Upon the Conversion, the Incentive Plan terminated and each participant in the Incentive Plan had his or her incentive units converted into shares of our common stock, which conversion was based on a conversion price determined by our board of directors immediately prior to the Conversion. To the extent an incentive unit award was subject to vesting, the common stock issued upon conversion continues to be subject to the same vesting schedule.
2018 Stock Incentive Plan
In September 2018, our board of directors adopted and our stockholders approved 2018 Plan, which became effective immediately prior to our IPO. The 2018 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, awards of restricted stock, RSUs and other stock-based awards. The number of shares of our common stock that are reserved for issuance under the 2018 Plan is the sum of (1) 4,067,007 shares of common stock; plus (2) the number of shares (up to 1,277,181) equal to the number of shares of our common stock issued in respect of incentive units granted under the Incentive Plan that were subject to vesting immediately prior to the effectiveness of the registration statement for our initial public offering that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by us at their original issuance price pursuant to a contractual repurchase right; plus (3) an annual increase, to be added the first day of each fiscal year, beginning with the fiscal year ending December 31, 2019 and continuing until, and including, the fiscal year ending December 31, 2028, equal to the lesser of 4,989,593 shares of our common stock, 4% of the number of shares of our common stock outstanding on the first day of the fiscal year or an amount determined by our board of directors. As of December 31, 2023, 2,099,162 shares were available for issuance under the 2018 Plan.
Our employees, officers, directors, consultants, and advisors are eligible to receive awards under the 2018 Plan; however, incentive stock options may only be granted to our employees. The shares of common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without the issuance of stock, expire, or are otherwise terminated (other than by exercise) under our 2018 Plan will be added back to the shares of common stock available for issuance under our 2018 Plan.
Pursuant to the terms of the 2018 Plan, our board of directors (or a committee delegated by our board of directors) administers the 2018 Plan and, subject to any limitations set forth in the 2018 Plan, will select the recipients of awards and determine:
•the number of shares of common stock covered by options and the dates upon which those options become exercisable;
•the type of options to be granted;
•the exercise price of options, which price must be at least equal to the fair market value of our common stock on the date of grant;
•the duration of options, which may not be in excess of ten years;
•the methods of payment of the exercise price of options; and
•the number of shares of our common stock subject to and the terms and conditions of any stock appreciation rights, awards of restricted stock, RSUs, other stock-based awards, including conditions for repurchase, measurement price, issue price and repurchase price and performance conditions (though the measurement price of stock appreciation rights must be at least equal to the fair market value of our common stock on the date of grant and the duration of such awards may not be in excess of ten years), if any.

Table of Contents
If our board of directors delegates authority to an officer to grant awards under the 2018 Plan, the officer will have the power to make awards to all of our employees, except officers and executive officers (as such terms are defined in the 2018 Plan). Our board of directors will fix the terms of the awards to be granted by such officer, the maximum number of shares subject to awards that such officer may grant and the time period in which such awards may be granted.
The 2018 Plan contains limits on awards that may be made under the 2018 Plan to our non-employee directors. In any calendar year, the sum of cash compensation paid to any non-employee director for service as a director and the value of awards under the 2018 Plan made to such non-employee director (calculated based on the grant date fair value of such awards for financial reporting purposes) may not exceed $1.0 million. However, our board of directors may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation.
In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of our common stock other than an ordinary cash dividend, we are required by the 2018 Plan to make equitable adjustments (or make substitute awards, if applicable), in a manner determined by our board, to:
•the number and class of securities available under the 2018 Plan;
•the share counting rules and sublimits under the 2018 Plan;
•the number and class of securities and exercise price per share of each outstanding option;
•the share and per-share provisions and measurement price of each outstanding stock appreciation right;
•the number of shares and the repurchase price per share subject to each outstanding restricted stock award; and
•the share and per-share related provisions and purchase price, if any, of each outstanding RSU award and other stock-based award.
Upon a merger or other reorganization event (as defined in our 2018 Plan), our board of directors, may, on such terms as our board determines (except to the extent specifically provided otherwise in an applicable award agreement or other agreement between the participant and us), take any one or more of the following actions pursuant to the 2018 Plan, as to some or all outstanding awards, other than awards of restricted stock:
•provide that all outstanding awards will be assumed or substantially equivalent awards will be substituted by the acquiring or succeeding corporation (or an affiliate thereof);
•upon written notice to a participant, provide that all of the participant's unvested awards will be forfeited immediately prior to the consummation of the reorganization event and/or unexercised awards will terminate immediately prior to the consummation of such transaction unless exercised to the extent exercisable, by the participant within a specified period following the date of such notice;
•provide that outstanding awards will become exercisable, realizable, or deliverable, or restrictions applicable to an award will lapse, in whole or in part, prior to or upon the reorganization event;

•provide that, in connection with our liquidation or dissolution, awards convert into the right to receive liquidation proceeds (if applicable, net of exercise, measurement or purchase price thereof and any applicable tax withholdings); or
•any combination of the foregoing.

Table of Contents
Our board of directors is not obligated by the 2018 Plan to treat all awards, all awards held by a participant, or all awards of the same type, identically.
In the case of certain RSUs, no assumption or substitution is permitted, and the RSUs will instead be settled in accordance with the terms of the applicable RSU agreement.
Upon the occurrence of a reorganization event other than our liquidation or dissolution, the repurchase and other rights with respect to each outstanding award of restricted stock will continue for the benefit of the successor company and will, unless our board of directors determines otherwise, apply to the cash, securities, or other property which our common stock is converted into or exchanged for pursuant to the reorganization event. However, our board may provide for the termination or deemed satisfaction of such repurchase or other rights under the restricted stock award agreement or any other agreement between the participant and us, either initially or by amendment. Upon the occurrence of a reorganization event involving our liquidation or dissolution, all restrictions and conditions on each outstanding restricted stock award will automatically be deemed terminated or satisfied, unless otherwise provided in the agreement evidencing the restricted stock award or in any other agreement between the participant and us.
Our board of directors may at any time provide that any award under the 2018 Plan shall become immediately exercisable in whole or in part, free of some or all restrictions or conditions, or otherwise realizable in whole or in part, as the case may be.
Unless our stockholders approve such action, the 2018 Plan provides that we may not (except as otherwise permitted in connection with a change in capitalization or reorganization event):
•amend any outstanding stock option or stock appreciation right granted under the 2018 Plan to provide an exercise or measurement price per share that is lower than the then-current exercise or measurement price per share of such outstanding award;
•cancel any outstanding option or stock appreciation right (whether or not granted under the 2018 Plan) and grant a new award under the 2018 Plan in substitution for the cancelled award (other than substitute awards permitted in connection with a merger or consolidation of an entity with us or our acquisition of property or stock of another entity) covering the same or a different number of shares of our common stock and having an exercise or measurement price per share lower than the then-current exercise or measurement price per share of the cancelled award;
•cancel in exchange for a cash payment any outstanding option or stock appreciation right with an exercise or measurement price per share above the then-current fair market value of our common stock (valued in the manner determined by (or in the manner approved by) our board of directors); or
•take any other action that constitutes a "repricing" within the meaning of Nasdaq Global Select Market rules or rules of any other exchange or marketplace on which our common stock is listed or traded.
No award may be granted under the 2018 Plan after ten years from the effectiveness of the 2018 Plan. Our board of directors may amend, suspend, or terminate the 2018 Plan at any time, except that stockholder approval will be required to comply with applicable law or stock market requirements.
2018 Employee Stock Purchase Plan
In September 2018, our board of directors adopted and our stockholders approved the 2018 ESPP, which became effective immediately prior to the effectiveness of the registration statement for our IPO. The 2018 ESPP is administered by our board of directors or by a committee appointed by our board of directors. The 2018 ESPP initially provided participating employees with the opportunity to purchase an aggregate of 311,850 shares of our common stock. The number of shares of our common stock reserved for issuance under the 2018 ESPP increased, pursuant to the terms of the 2018 ESPP, by additional shares equal to 1% of our then-outstanding common stock, effective as of January 1 of each year. As of December 31, 2023, 2,044,434 shares remained available for purchase.
49
Table of Contents
All of our employees and employees of any of our designated subsidiaries, as defined in the 2018 ESPP, are eligible to participate in the 2018 ESPP, provided that:
•such person is customarily employed by us or a designated subsidiary for more than 20 hours a week and for more than five months in a calendar year;
•such person has been employed by us or by a designated subsidiary for at least three months prior to enrolling in the 2018 ESPP; and
•such person was our employee or an employee of a designated subsidiary on the first day of the applicable offering period under the 2018 ESPP.
We retain the discretion to determine which eligible employees may participate in an offering under applicable Treasury regulations.
We expect to make one or more offerings to our eligible employees to purchase stock under the 2018 ESPP beginning at such time and on such dates as our board of directors may determine, or the first business day thereafter. Each offering will consist of a six-month offering period during which payroll deductions will be made and held for the purchase of our common stock at the end of the offering period. Our board of directors or a committee appointed by our board, may, at its discretion, choose a different period of not more than 12 months for offerings. The first offering period under our 2018 ESPP commenced on January 1, 2020.
On each offering commencement date, each participant will be granted the right to purchase, on the last business day of the offering period, a number of shares of our common stock determined by multiplying $2,083 by the number of full months in the offering period and dividing that product by the closing price of our common stock on the first day of the offering period. No employee may be granted an option under the 2018 ESPP that permits the employee's rights to purchase shares under the 2018 ESPP and any other employee stock purchase plan of ours or of any of our subsidiaries to accrue at a rate that exceeds $25,000 of the fair market value of our common stock (determined as of the first day of each offering period) for each calendar year in which the option is outstanding. (Our board or a committee appointed by our board may also set a fixed maximum number of shares that a participant in the 2018 ESPP may purchase in any offering period provided that the number may not be greater than the number described in the first sentence of this paragraph and must be subject to the limit described in the second sentence of this paragraph). In addition, no employee may purchase shares of our common stock under the 2018 ESPP that would result in the employee owning 5% or more of the total combined voting power or value of our stock or the stock of any of our subsidiaries.
On the commencement date of each offering period, each eligible employee may authorize up to a maximum of 15% of the compensation he or she receives during the offering period to be deducted by us during the offering period. Each employee who continues to be a participant in the 2018 ESPP on the last business day of the offering period will be deemed to have exercised an option to purchase from us the number of whole shares of our common stock that his or her accumulated payroll deductions on such date will buy, not in excess of the maximum numbers set forth above. Under the terms of the 2018 ESPP, the purchase price shall be determined by our board of directors for each offering period and will be at least 85% of the applicable closing price of our common stock. If our board of directors does not make a determination of the purchase price, the purchase price will be 85% of the lesser of the closing price of our common stock on the first business day of the offering period or the last business day of the offering period.
An employee may at any time prior to the close of business on the fifteenth business day (or such other number of days as we may determine) prior to the end of an offering period, and for any reason, permanently withdraw from participation in an offering prior to the end of an offering period and permanently withdraw the balance accumulated in the employee's account. If an employee elects to discontinue his or her payroll deductions during an offering period but does not elect to withdraw his or her funds, funds previously deducted will be applied to the purchase of common stock at the end of the offering period. If a participating employee's employment ends before the last business day of an offering period, no additional payroll deductions will be taken and the balance in the employee's account will be paid to the employee.
We will be required to make equitable adjustments to the extent determined by our board of directors or a committee of our board of directors to the number and class of securities available under the 2018 ESPP, the share limitations under the 2018 ESPP and the purchase price for an offering period under the 2018 ESPP to reflect stock splits, reverse stock splits, stock dividends, recapitalizations, combinations of shares, reclassifications of shares, spin-offs and other similar changes in capitalization or events or any dividends or distributions to holders of our common stock other than ordinary cash dividends.

Table of Contents
In connection with a merger or other reorganization event (as defined in the 2018 ESPP), our board of directors or a committee of our board of directors may take any one or more of the following actions as to outstanding options to purchase shares of our common stock under the 2018 ESPP on such terms as our board of directors or committee determines:
•provide that options shall be assumed, or substantially equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof);
•upon written notice to employees, provide that all outstanding options will be terminated immediately prior to the consummation of such reorganization event and that all such outstanding options will become exercisable to the extent of accumulated payroll deductions as of a date specified by our board of directors or committee in such notice, which date shall not be less than ten days preceding the effective date of the reorganization event;
•upon written notice to employees, provide that all outstanding options will be cancelled as of a date prior to the effective date of the reorganization event and that all accumulated payroll deductions will be returned to participating employees on such date;
•in the event of a reorganization event under the terms of which holders of our common stock will receive upon consummation thereof a cash payment for each share surrendered in the reorganization event, change the last day of the offering period to be the date of the consummation of the reorganization event and make or provide for a cash payment to each employee equal to (1) the cash payment for each share surrendered in the reorganization event times the number of shares of our common stock that the employee's accumulated payroll deductions as of immediately prior to the reorganization event could purchase at the applicable purchase price, where the cash payment for each share surrendered in the reorganization event is treated as the fair market value of our common stock on the last day of the applicable offering period for purposes of determining the purchase price and where the number of shares that could be purchased is subject to the applicable limitations under the 2018 ESPP minus (2) the result of multiplying such number of shares by the purchase price; and/or
•provide that, in connection with our liquidation or dissolution, options shall convert into the right to receive liquidation proceeds (net of the purchase price thereof).
Our board of directors may at any time, and from time to time, amend or suspend the 2018 ESPP, or any portion of the 2018 ESPP. We will obtain stockholder approval for any amendment if such approval is required by Section 423 of the Code. Further, our board of directors may not make any amendment that would cause the 2018 ESPP to fail to comply with Section 423 of the Code. The 2018 ESPP may be terminated at any time by our board of directors. Upon termination, we will refund all amounts in the accounts of participating employees.
Limitations on Liability and Indemnification
Our restated certificate of incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law and provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty or other duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:
•for any breach of the director's duty of loyalty to us or our stockholders;
•for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
•for voting for or assenting to unlawful payments of dividends, stock repurchases or other distributions; or
•for any transaction from which the director 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 such 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.
51
Table of Contents
In addition, our restated certificate of incorporation provides that we must indemnify our directors and officers and we must advance expenses, including attorneys' fees, to our directors and officers in connection with legal proceedings, subject to very limited exceptions.
We maintain a general liability insurance policy that covers specified liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers. We have entered into indemnification agreements with all of our directors and executive officers. These indemnification agreements may require us, among other things, to indemnify each such director or officer for some expenses, including attorneys' fees, judgments, fines, and settlement amounts incurred by him in any action or proceeding arising out of his or her service as one of our directors or officers.
Some of our non-employee directors may, through their relationships with their employers, be insured or indemnified against specified liabilities incurred in their capacities as members of our board of directors.
Insofar as indemnification for liabilities arising under the Securities Act of 1933, or the Securities Act, may be permitted to directors, executive officers or persons controlling us, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
Rule 10b5-1 Sales Plans

Our directors and executive officers may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or officer when entering into the plan, without further direction from the director or officer. The director or officer may amend or terminate the plan in some circumstances. Our directors and executive officers may also buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material, nonpublic information subject to compliance with the terms of our Insider Trading Policy and our pre-clearance procedures.
Director Compensation
We do not pay any compensation to our President and Chief Executive Officer in connection with his service on our board of directors. The compensation that we pay to our President and Chief Executive Officer is discussed earlier in this "Executive and Director Compensation" section.
Under our director compensation program, we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairperson of the board and of each committee receive higher retainers for such service. These fees are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment will be prorated for any portion of such quarter that the director is not serving on our board of directors. In June 2023, based on a review of our the cash and equity compensation paid to our board of directors versus directors of our peer companies, and with assistance of Aon, our compensation consultant, we amended our director compensation program to add fees for the lead independent director and approve fees for the science and technology committee, as follows:
Non-Employee Member

We also reimburse our non-employee directors for reasonable travel and other expenses incurred in connection with attending our board of director and committee meetings.

In addition, under our director compensation program, as amended in June 2023, each non-employee director receives under the 2018 Plan, upon his or her initial election to our board of directors, equity having an aggregate grant date fair value of $750,000 as calculated by the company in accordance with ASC Topic 718, with two-thirds of the value of such award being issued as an option to purchase common stock, or the Initial Option Grant and one-third of the value of such award being issued in RSUs, or the Initial RSU Grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Subject to the non-employee director's continued service as a director, (a) the Initial Option Grant will vest with respect to 1/36th of the shares of common stock subject thereto at the end of each successive one-month period following the grant date until the third anniversary of the grant date and (b) the Initial RSU Grant will vest annually over three years until the third anniversary of the grant date, and in the event of a change in control of the Company, the vesting schedule of the Initial Option Grant and the Initial RSU Grant will accelerate in full. The exercise price of the Initial Option Grant will be equal to the fair market value of the common stock on the date of grant, which shall be the closing trading price.
Further, on the date of each of our annual meetings of stockholders, each non-employee director who has served on our board of directors for at least six months receives, under the 2018 Plan, equity having an aggregate grant date fair value of $375,000 as calculated by the company in accordance with ASC Topic 718, with two-thirds of the value of such award being issued as an option to purchase common stock, or the Annual Option Grant, and one-third of the value of such award being issued in RSUs, or the Annual RSU Grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Each of the Annual Option Grant and Annual RSU Grant will vest in full on the earlier of the first anniversary of the grant date or the first board of directors meeting held after the following annual meeting of stockholders, subject to the non-employee director's continued service as a director. All options issued to our non-employee directors under our director compensation program are issued at exercise prices equal to the fair market value of our common stock on the date of grant.

Prior to June 2023, each non-employee director received under the 2018 Plan, upon his or her initial election to our board of directors, an option to purchase approximately $750,000 of shares of our common stock based on the closing price of our common stock on the date of grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Each of these options vested in equal monthly installments at the end of each month following the date of grant through the third anniversary of the date of grant, subject to the non-employee director's continued service as a director, employee, or consultant. Further, on the date of each of our annual meetings of stockholders, each non-employee director who has served on our board of directors for at least six months received, under the 2018 Plan, an option to purchase approximately $375,000 of shares of our common stock, based on the closing price of our common stock on the date of grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Each of these options vested in full on the one-year anniversary of the date of grant (or, if earlier, the date of our next annual meeting of stockholders following the date of grant), subject to the non-employee director's continued service as a director. All options issued to our non-employee directors under our director compensation program were issued at exercise prices equal to the fair market value of our common stock on the date of grant.

The following table sets forth information regarding compensation earned by our non-employee directors during the year ended December 31, 2023. There were no outstanding equity awards held by our non-employee directors as of December 31, 2023 other than as described in footnote 1 to the following table.

PROPOSAL NO. 3-RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2024
Our stockholders are being asked to ratify the appointment by the audit committee of the board of directors of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024.
The audit committee is solely responsible for selecting our independent registered public accounting firm for the fiscal year ending December 31, 2024. Stockholder approval is not required to appoint Deloitte & Touche LLP as our independent registered public accounting firm. However, our board of directors believes that submitting the appointment of Deloitte & Touche LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain Deloitte & Touche LLP. If the selection of Deloitte & Touche LLP is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of our company and our stockholders.
A representative of Deloitte & Touche LLP is expected to virtually attend the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.
We incurred the following fees from Deloitte & Touche LLP for the audit of the consolidated financial statements and for other services provided during the years ended December 31, 2023 and 2022.
2023 2022
Audit fees (1) $ 971,250 $ 869,000
Audit-related fees - -
Tax fees (2) - 25,000
All other fees (3) 1,895 -
Total fees $ 973,145 $ 894,000
(1)Audit fees consist of fees billed for professional services by Deloitte & Touche LLP for audit and quarterly review of our consolidated financial statements and related services that are normally provided in connection with statutory and regulatory filings or engagements, including registration statements.
(2)Tax fees consist of fees billed for professional services by Deloitte & Touche LLP for tax consultation.
(3)All other fees consist of user access fees to Deloitte Accounting Research Tool.
The aggregate fees included in the audit fees and tax fees are those fees billed for the fiscal year.
Audit Committee Pre-Approval Policy and Procedures
The audit committee of our board of directors has adopted policies and procedures for the pre-approval of audit and non-audit services for the purpose of maintaining the independence of our independent auditor. We may not engage our independent auditor to render any audit or non-audit service unless either the service is approved in advance by the audit committee, or the engagement to render the service is entered into pursuant to the audit committee's pre-approval policies and procedures.
From time to time, our audit committee may pre-approve services that are expected to be provided to us by the independent auditor during the following 12 months. At the time such pre-approval is granted, the audit committee must identify the particular pre-approved services in a sufficient level of detail so that our management will not be called upon to make a judgment as to whether a proposed service fits within the pre-approved services and, at each regularly scheduled meeting of the audit committee following such approval, management or the independent auditor shall report to the audit committee regarding each service actually provided to us pursuant to such pre-approval. The audit committee has delegated to its chairperson the authority to grant pre-approvals of audit or non-audit services to be provided by the independent auditor. Any approval of services by the chairperson of the audit committee is reported to the committee at its next regularly scheduled meeting.
55
Table of Contents
During our 2023 and 2022 fiscal years, no services were provided to us by Deloitte & Touche LLP other than in accordance with the pre-approval policies and procedures described above.
The board of directors recommends voting "FOR" Proposal No. 3 to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024.
Any properly submitted proxy will be voted in favor of the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024 unless a contrary specification is made in the proxy.

REPORT OF THE AUDIT COMMITTEE
Our audit committee has reviewed our audited financial statements for the year ended December 31, 2023 and discussed them with our management and our independent registered public accounting firm, Deloitte & Touche LLP.
Our audit committee has also received from, and discussed with, Deloitte & Touche LLP various communications that Deloitte & Touche LLP is required to provide to our audit committee, including the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC.
In addition, Deloitte & Touche LLP provided our audit committee with the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the audit committee concerning independence, and the audit committee has discussed with the company's independent registered public accounting firm their independence.
Based on the review and discussions referred to above, our audit committee recommended to our board of directors that our financial statements audited by Deloitte & Touche LLP be included in our Annual Report on Form 10-K for the year ended December 31, 2023.

PRINCIPAL STOCKHOLDER
The following table sets forth information with respect to the beneficial ownership of our common stock, as of March 31, 2024 by:
•each person known by us to beneficially own more than 5% of our common stock;
•each of our directors;
•each of our named executive officers; and
•all of our executive officers and directors as a group.
The column entitled "Percentage of Shares Beneficially Owned" is based on a total of 68,308,405 shares of our common stock outstanding as of March 31, 2024.
The number of shares beneficially owned by each stockholder is determined under rules issued by the Securities and Exchange Commission and includes voting or investment power with respect to securities. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. Unless otherwise indicated, in computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, warrants, or other rights held by such person that are currently exercisable or will become exercisable within 60 days after March 31, 2024 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Therefore, the denominator used in calculating beneficial ownership of each of the stockholders may be different. Unless otherwise indicated, the address of all listed stockholders is 5 Science Park, 395 Winchester Ave., New Haven, CT 06511. Each of the stockholders listed has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

Policies and Procedures for Related Person Transactions
We have adopted a written related person transaction policy to set forth policies and procedures for the review and approval or ratification of related person transactions. We amended this policy in June 2022 to make certain clarifying adjustments. This policy covers any transaction, arrangement, or relationship, or any series of similar transactions, arrangements, or relationships, in which we were or are to be a participant, the amount involved exceeds $120,000, and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness, and employment by us of a related person.

Our related person transaction policy contains exceptions for any transaction or interest that is not considered a related person transaction under SEC rules as in effect from time to time. In addition, the policy provides that an interest arising solely from a related person's position as an executive officer of another entity that is a participant in a transaction with us will not be subject to the policy if each of the following conditions is met:
•the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity;
•the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction; and
•the amount involved in the transaction equals less than the greater of $200,000 or 5% of the annual gross revenue of the company.
The policy provides that any related person transaction proposed to be entered into by us must be reported to our Chief Financial Officer and will be reviewed and approved by our audit committee in accordance with the terms of the policy, prior to effectiveness or consummation of the transaction whenever practicable. The policy provides that if our Chief Financial Officer determines that advance approval of a related person transaction is not practicable under the circumstances, our audit committee will review and, in its discretion, may ratify the related person transaction at the next meeting of the audit committee following such transaction or following the date that such transaction comes to the attention of the Chief Financial Officer. The policy also provides that alternatively, our Chief Financial Officer may present a related person transaction arising in the time period between meetings of the audit committee to the chair of the audit committee, who will review and may approve the related person transaction, subject to ratification by the audit committee at the next meeting of the audit committee.
In addition, the policy provides that any related person transaction previously approved by the audit committee or otherwise already existing that is ongoing in nature will be reviewed by the audit committee annually to ensure that such related person transaction has been conducted in accordance with the previous approval granted by the audit committee, if any, and that all required disclosures regarding the related person transaction are made.
The policy provides that transactions involving compensation of executive officers will be reviewed and approved by our compensation committee in the manner to be specified in the charter of the compensation committee.
A related person transaction reviewed under this policy will be considered approved or ratified if it is authorized by the audit committee in accordance with the standards set forth in the policy after full disclosure of the related person's interests in the transaction. As appropriate for the circumstances, the policy provides that the audit committee will review and consider:
•the related person's interest in the related person transaction;
•the approximate dollar value of the amount involved in the related person transaction, including the related person's position(s) or relationship(s) with, or ownership in, a firm, corporation or other entity that is a party to, or has an interest in, the related person transaction;
•the approximate dollar value of the amount of the related person's interest in the related person transaction without regard to the amount of any profit or loss;
•whether the related person transaction was undertaken in the ordinary course of business of our company;
•whether the related person transaction with the related person is proposed to be, or was, entered into on terms no less favorable to us than the terms that could have been reached with an unrelated third party;
•the purpose of, and the potential benefits to us of, the related person transaction; and
•any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
The policy provides that the audit committee will review all relevant information available to it about the related person transaction. The policy provides that the audit committee may approve or ratify the related person transaction only if the

audit committee determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. The policy provides that the audit committee may, in its sole discretion, impose such conditions as it deems appropriate on us or the related person in connection with approval of the related person transaction.
