(2)Ratify the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024; and
(3)Transact any other business that may properly come before the Annual Meeting or any adjournments or postponements thereof.
Each of these proposals is more fully described in the accompanying proxy statement, which each stockholder is encouraged to carefully read.
Your vote is very important. Whether or not you plan to attend the Annual Meeting, you are encouraged to submit your proxy and voting instructions via the Internet, by telephone or, if you received a paper copy of the meeting materials by mail, by completing, signing and dating the enclosed proxy card as promptly as possible and returning it in the enclosed envelope (to which no postage need be affixed if mailed in the United States). Even if you have given your proxy, you may still vote in person if you attend the Annual Meeting or during the Annual Meeting by visiting www.virtualshareholdermeeting.com/wgs2024 with your 12-digit control number assigned by Continental Stock Transfer & Trust Company included on your proxy card or obtained from them via email. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the Annual Meeting, you must obtain from the record holder a proxy issued in your name. You may revoke a previously delivered proxy at any time prior to the Annual Meeting. You may do so automatically by voting in person at the Annual Meeting or online during the Annual Meeting, or by delivering to us a written notice of revocation or a duly executed proxy bearing a date later than the date of the proxy being revoked.

In addition, unless otherwise stated in this proxy statement, all share amounts, exercise prices and other amounts set forth herein have been adjusted for the impact of a 1-for-33 reverse stock split of our Class A common stock, par value $0.0001 per share (“Class A Common Stock”), that became effective on May 4, 2023 (the “Reverse Stock Split”).
INFORMATION ABOUT SOLICITATION AND VOTING
This proxy statement and the accompanying form of proxy are furnished in connection with the solicitation of proxies by our board of directors (the “Board” or “Board of Directors”) for use at our 2024 annual meeting of stockholders and any postponements, adjournments or continuations thereof (the “Annual Meeting”). The Annual Meeting will be held at the Company’s corporate headquarters at 333 Ludlow Street, North Tower, Stamford, Connecticut 06902 on June 20, 2024 at 9:00 a.m. Eastern Time. The Annual Meeting will be held through a “hybrid” model where participants can either attend in person or online. References to our website in this proxy statement are not intended to function as hyperlinks and the information contained on our website is not intended to be incorporated into this proxy statement.
The Notice of Internet Availability of Proxy Materials, or the Notice of Annual Meeting, this proxy statement and the form of proxy are first being distributed and made available on the Internet on or about April 29, 2024 to all the Company’s stockholders entitled to vote at the Annual Meeting.
INTERNET AVAILABILITY OF PROXY MATERIALS
In accordance with U.S. Securities and Exchange Commission (the “SEC”), rules, we are using the Internet as our primary means of furnishing proxy materials to stockholders. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice of Internet Availability of Proxy Materials with instructions for accessing the proxy materials, including our proxy statement and annual report, and voting via the Internet. The Notice of Internet Availability of Proxy Materials also provides information on how stockholders may obtain paper copies of our proxy materials if they so choose. We believe this rule makes the proxy distribution process more efficient, less costly and helps in conserving natural resources.

Record Date; Quorum
Only holders of record of our Class A Common Stock at the close of business on April 24, 2024 (the “Record Date”) will be entitled to vote at the Annual Meeting. At the close of business on the April 24, 2024, we had 26,150,866 shares of Class A Common Stock outstanding and entitled to vote.

The holders of a majority of the voting power of the shares of our Class A Common Stock entitled to vote at the Annual Meeting as of the Record Date must be present at the Annual Meeting in order to hold the Annual Meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the Annual Meeting if you are present and vote in person at the Annual Meeting (including through the virtual meeting platform) or if you have properly submitted a proxy.
3


Voting Rights
In deciding all matters at the Annual Meeting, as of the close of business on the Record Date, each share of Class A Common Stock represents one vote. We do not have cumulative voting rights for the election of directors. You may vote all shares owned by you as of the Record Date, including (i) shares held directly in your name as the stockholder of record and (ii) shares held for you as the beneficial owner in street name through a broker, bank, trustee, or other nominee.
Stockholder of Record: Shares Registered in Your Name. If, on the Record Date, your shares were registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the Annual Meeting or vote by telephone, through the Internet or, if you request or receive paper proxy materials, by filling out and returning the proxy card.
Beneficial Owner: Shares Registered in the Name of a Broker or Nominee. If, on the Record Date, your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in “street name.” As a beneficial owner, you have the right to direct your nominee on how to vote the shares held in your account, and your nominee has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. However, the organization that holds your shares is considered the stockholder of record for purposes of voting at the Annual Meeting. Because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the Annual Meeting.

Impact on the Vote of Broker Non-Votes, Abstentions and Withholding from Voting.
A proxy submitted by a stockholder may indicate that the shares represented by the proxy are not being voted (stockholder withholding) with respect to a particular matter. Further, broker non-votes occur when shares held by a broker for a beneficial owner are not voted because the broker did not receive voting instructions from the beneficial owner and lacked discretionary authority to vote the shares.
The shares subject to a proxy which are not being voted on a particular matter because of either stockholder withholding or broker non-votes will count for purposes of determining the presence of a quorum, but are not treated as votes cast and, therefore, will have no effect on the election of directors and the ratification of the appointment of our independent registered public accounting firm. However, brokers have limited discretionary authority to vote shares that are beneficially owned. While a broker is entitled to vote shares held for a beneficial owner on “routine” matters without instructions from the beneficial owner of those shares, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on “non-routine” matters. At our Annual Meeting, only Proposal No. 2 is considered a routine matter and brokers have discretionary authority to vote shares that are beneficially owned on Proposal No. 2. If a broker chooses not to vote shares for or against Proposal No. 2, it would have the same effect as an abstention. The other proposal presented at the Annual Meeting, Proposal No.
4


1, is a non-routine matter and therefore broker non-votes are not deemed to be shares entitled to vote on and will have no effect on the proposal.
Abstentions will be counted as present and entitled to vote for purposes of determining whether a quorum is present. At the Annual Meeting, abstentions will have no effect on Proposal No. 1.

Voting Instructions; Voting of Proxies
Vote By Telephone or InternetVote By MailVote in Person
You may vote by telephone or through the Internet—in order to do so, please follow the instructions shown on your proxy card.
If you received a paper copy of the proxy materials by mail, you may vote by mail by completing, signing and dating the enclosed proxy card and promptly return it in the envelope provided or, if the envelope is missing, please mail your completed proxy card to Vote Processing, c/o Broadridge Financial Solutions, Inc., 51 Mercedes Way, Edgewood, New York 11717. Your completed, signed, and dated proxy card must be received prior to the Annual Meeting.
You may attend the Annual Meeting in person (including through the virtual meeting platform) and vote during the meeting. See “Attending the Annual Meeting” above.
Votes submitted by telephone or through the Internet must be received by 11:59 p.m. Eastern Time on June 19, 2024. Submitting your proxy, whether by telephone, through the Internet or, if you request or receive a paper proxy card, by mail will not affect your right to vote in person should you decide to attend the Annual Meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct your nominee on how to vote your shares. Your vote is important. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure that your vote is counted.
All proxies will be voted in accordance with the instructions specified on the proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the Annual Meeting, your shares will be voted in accordance with the recommendations of our Board stated above.
If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute “broker non-votes” (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, broker non-votes will be counted for the purpose of establishing a quorum for the Annual Meeting.
If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each proxy card and vote each proxy card by telephone, through the Internet, or by mail. If you requested or received paper proxy materials and you intend to vote by mail, please complete, sign, and return each proxy card you received to ensure that all of your shares are voted.
We strongly recommend that you vote your shares in advance of the meeting as instructed above, even if you plan to attend the Annual Meeting in person.

Revocability of Proxies
A stockholder of record who has given a proxy may revoke it at any time before it is exercised at the Annual Meeting by:
delivering to our Corporate Secretary by mail a written notice stating that the proxy is revoked;
signing and delivering a proxy bearing a later date;
voting again by telephone or through the Internet; or
attending in person (including through the virtual meeting platform) and voting during the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).
Please note, however, that if your shares are held of record by a broker, bank, or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions.
Expenses of Soliciting Proxies
We will pay the expenses of soliciting proxies, including preparation, assembly, printing, and mailing of this proxy statement, the proxy, and any other information furnished to stockholders. Following the original distribution of the soliciting materials, we and our agents, including directors, officers, and other employees, without additional compensation, may solicit proxies by mail, email, telephone, facsimile, by other similar means, or in person. Following the original distribution of the soliciting materials, we will request brokers, custodians, nominees, and other record holders to forward copies of the soliciting materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, we, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials or vote through the Internet, you are responsible for any Internet access charges you may incur.
Voting Results
Voting results will be tabulated and certified by the inspector of elections appointed for the Annual Meeting. The preliminary voting results will be announced at the Annual Meeting. The final results will be tallied by the inspector of elections and filed with the SEC in a current report on Form 8-K within four business days of the Annual Meeting.
CORPORATE GOVERNANCE
We are strongly committed to good corporate governance practices. These practices provide an important framework within which our Board and management can pursue our strategic objectives for the benefit of our stockholders.
Corporate Governance Guidelines
Our Board has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, board committee structure and functions, stock ownership guidelines, and other policies for the governance of the Company. Our Corporate Governance Guidelines are available without charge on the investor relations section of our website at www.GeneDx.com. Information contained on or accessible through such website is not a part of this proxy statement, and the inclusion of the website address in this proxy statement is an inactive textual reference only.
Director Independence
Our Class A Common Stock is traded on the Nasdaq Global Select Market (“Nasdaq”). The rules of Nasdaq require that a majority of the Company’s board of directors be independent. An “independent director” is defined generally as a person other than an executive officer or employee the Company or any other individual having a relationship which, in the opinion of the issuer’s board of directors, would interfere with the exercise of independent judgement in carrying out the responsibilities of a director. Our Board has determined that each individual currently serving on our board, other than Ms. Stueland and Mr. Ryan, qualifies as an independent director under Nasdaq listing standards.
Board of Directors
Our Board oversees our business affairs and works with our Chief Executive Officer and other senior management to determine our strategy and mission. In fulfilling its responsibilities, our Board is involved in strategic and operational planning, financial reporting, governance, compliance and risk oversight.
6


Board Leadership Structure
Our Corporate Governance Guidelines provide that our Board will be free to choose its chairperson in any way that it considers in the best interests of our Company at any giving point in time, and our Nominating and Corporate Governance Committee charter provides that the committee will periodically consider the leadership structure of our Board and make such recommendations to our Board with respect thereto as appropriate. Our Board currently believes that it should maintain flexibility in determining the Board leadership structure that is appropriate for the Company at a given time.
Currently, our leadership structure separates the roles of Chairman of the Board and Chief Executive Officer, with Ms. Stueland serving as our Chief Executive Officer and Mr. Ryan serving as the Chairman of the Board. Our Board believes that separating these roles provides the appropriate balance between strategy development, flow of information between management and the Board, and oversight of management. We believe this provides guidance for our Board, while also positioning our Chief Executive Officer as the leader of the Company in the eyes of our partners, customers, employees, and other stakeholders. As Chairman, Mr. Ryan, among other responsibilities, presides over regularly scheduled meetings of the Board, serves as a liaison between the directors, and performs such additional duties as our Board may otherwise determine and delegate. Our Board recognizes the time, effort, and energy that Ms. Stueland is required to devote to her position as our Chief Executive Officer in the current business environment, as well as the commitment required for a person to serve as our Chairman, particularly as the Board’s oversight responsibilities continue to grow. By having Mr. Ryan serve as Chairman of the Board, Ms. Stueland is better able to focus her attention on running our Company.
The Board’s Role in Risk Oversight
Although our management is primarily responsible for managing our risk exposure on a daily basis, our Board oversees the risk management processes. Our Board, as a whole, determines the appropriate level of risk for our Company, assesses the specific risks that we face, and reviews management’s strategies for adequately mitigating and managing the identified risks. Although our Board administers this risk management oversight function, our Audit Committee supports our Board in discharging its oversight duties and addresses risks inherent in its area, including with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures. Our Compensation Committee assists our Board in assessing and mitigating any risks that may be created by our compensation plans, practices and policies. Our Nominating and Corporate Governance Committee is charged with assisting our Board in fulfilling its oversight responsibilities with respect to the management of risk associated with Board membership and corporate governance.
Hedging Policy
Our insider trading policy prohibits GeneDx employees, officers and directors from engaging in hedging or monetization transactions involving GeneDx securities, including, among other things, zero-cost collars and forward sale contracts or the contribution of GeneDx securities to exchange funds that could be interpreted as having the effect of hedging in GeneDx securities. Additionally, our insider trading policy prohibits GeneDx employees, officers and directors from engaging in transactions involving options or other derivative securities on GeneDx’s securities, such as puts and calls, whether on an exchange or in any other market, engaging in short sales of GeneDx’s securities, including short sales “against the box,” and using or pledging GeneDx securities as collateral in a margin account or as collateral for a loan.
Clawback Policy
In accordance with SEC and Nasdaq requirements, the Compensation Committee (as defined below) adopted an executive compensation recovery policy regarding the adjustment or recovery of certain incentive awards or payments made to current or former executive officers in the event that we are required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws. In general, the policy provides that, unless an exception applies, we will seek to recover compensation that is awarded to an executive officer based on the Company’s attainment of a financial metric during the three-year period prior to the fiscal year in which the restatement occurs, to the extent such compensation exceeds the amount that would have been awarded based on the restated financial results.
Committees of the Board of Directors
Our Board has the authority to appoint standing and special committees to perform certain management and administration functions. Our Board has established a standing Audit Committee (the “Audit Committee”), a standing Compensation Committee (the “Compensation Committee”), and a standing Nominating and Corporate Governance Committee (the “Nominating and Governance Committee”). The composition and responsibilities of each committee are described below. Members serve on these
7


committees until their resignation or until otherwise determined by the Board. The charters for each of these committees are available on our website at www.GeneDx.com. Information contained on or accessible through our website is not a part of this proxy statement, and the inclusion of such website address in this proxy statement is an inactive textual reference only.

Audit Committee
Our Audit Committee is comprised of Messrs. Meister and Pfenniger, and Ms. Leproust, with Mr. Meister as the chairman of the Audit Committee. The Board has determined that the composition of our Audit Committee meets the requirements for independence under the current Nasdaq and SEC rules and regulations, and that each member of the Audit Committee is financially literate.
In making the determination regarding independence, our Board considered the relationships that each member of our Audit Committee has with the Company and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each member of our Audit Committee and the nature of his or her service to the Company. In particular, our Board has determined that, although Mr. Meister falls outside the safe harbor provisions of Rule 10A-3(e)(1)(ii)(A) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), Mr. Meister nevertheless meets the independence requirements contemplated by Rule 10A-3 under the Exchange Act. The safe harbor provisions of Rule 10A-3(e)(1)(ii)(A) exempt holders of 10% or less of any class of voting securities of an issuer from being deemed to be in control of, or an affiliate of, that issuer. As of April 15, 2024, Mr. Meister indirectly beneficially owned approximately 9.4% of our outstanding Class A Common Stock (which includes certain shares of Common Class A Common Stock issuable upon the exercise of certain private placement warrants). See “Security Ownership of Certain Beneficial Ownership and Management.” The existence of the safe harbor set forth in Rule 10A-3(e)(1)(ii)(A), however, does not create a presumption in any way that a person exceeding the 10% threshold controls or is otherwise an affiliate of an issuer, and our Board, after considering, among other factors, Mr. Meister’s direct ownership in our outstanding Class A Common Stock, his indirect beneficial ownership of our outstanding Class A Common Stock relative to other significant stockholders, the exercise price and the likelihood of the exercise of the private placement warrants, and his service to us solely in the capacity as a director, has determined that Mr. Meister satisfies the audit committee membership requirements established by the SEC and under the Nasdaq rules.
In addition, the Board has determined that Mr. Meister is an “audit committee financial expert” as defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act of 1933, as amended (the “Securities Act”). This designation does not impose on him any duties, obligations or liabilities that are greater than are generally imposed on members of our Audit Committee and our Board. Our Audit Committee is directly responsible for, among other things:
reviewing and discussing with management and the independent auditors our quarterly and annual financial results and earnings releases, our annual audited and quarterly unaudited financial statements and annual and quarterly reports on Form 10-K and 10-Q and recommend to the Board whether the annual financial statements should be included in our Annual Reports on Form 10-K;
selecting and hiring the independent registered public accounting firm;
monitoring the qualifications, independence and performance of our independent auditors;
the preparation of the Audit Committee report to be included in the proxy statement for our annual meeting;
our compliance with legal and regulatory requirements;
8


overseeing our accounting and financial reporting processes, including our financial statement audits and the integrity of our financial statements;
reviewing and approving related-person transactions; and
overseeing our financial risks, enterprise exposures, cybersecurity risks and other risks as it deems necessary or appropriate.
Compensation Committee
Our Compensation Committee is comprised of Messrs. Casdin and Ruch and Ms. Leproust, with Mr. Ruch as the chairman of our Compensation Committee. The Board has determined that each member of our Compensation Committee is a non-employee director, as defined by Rule 16b-3 promulgated under the Exchange Act, and meets the requirements for independence under the current Nasdaq listing standards and SEC rules and regulations. Our Compensation Committee is responsible for, among other things:
evaluating, recommending, approving and reviewing executive officer compensation arrangements, plans, policies and programs;
evaluating and recommending non-employee director compensation arrangements for determination by our Board;
administering our cash-based and equity-based compensation plans; and
overseeing our compliance with regulatory requirements associated with the compensation of directors, officers and employees.
The Compensation Committee may retain compensation advisors and other compensation consultants.

The Compensation Committee has the authority to retain the services and obtain the advice of external advisors, including compensation consultants, legal counsel and other advisors to assist in the evaluation of executive officer compensation. The Compensation Committee has engaged Radford Data & Analytics of Aon, our independent compensation consultant (“Radford”), to conduct an executive compensation market analysis and review of our short-term cash and long-term equity incentive practices to help ensure they align with market practices. Radford reviewed and advised on all principal aspects of our executive compensation program, including:
Assisting in developing a peer group of publicly traded companies to be used to help assess the competitiveness of executive compensation;
Assisting in ensuring a competitive compensation framework;
Meeting regularly with the Compensation Committee to review all elements of executive compensation, including the competitiveness of our executive compensation program;
Assisting in the competitive assessment of the short-term cash and long-term equity incentive plans designs; and
Assisting in the risk assessment of our compensation program.
Outside of its services to the Compensation Committee, Radford provides certain other miscellaneous services to us, including those related to provision of surveys. The Compensation Committee evaluated the independence of Radford and determined that it is independent. The Compensation Committee also determined that Radford’s work for the Company in 2023 did not raise any conflicts of interest.
Role of Compensation Committee and Executive Officers in Compensation Decisions
Our Compensation Committee works in close collaboration with the full Board on executive compensation matters. Following the adoption of our Compensation Committee charter, our Compensation Committee has adopted a practice of informing and consulting with the full Board concerning the establishment of performance goals and objectives for our Chief Executive Officer, evaluating our Chief Executive Officer’s performance in light of the goals and objectives that were set, and determining the Chief Executive Officer’s compensation based on that evaluation. Our Chief Executive Officer serves on our Board but recuses herself from any deliberations about her compensation. For fiscal year 2023, Katherine Stueland, our current Chief Executive Officer, prepared an analysis for the Compensation Committee to recommend each element of compensation to be paid to all executive officers except for themselves. The Compensation Committee considered their recommendations, along with an analysis from Radford, in approving the compensation of our executive officers other than Chief Executive Officer.

Nominating and Corporate Governance Committee
Our Nominating and Governance Committee is comprised of Messrs. Ruch and Casdin and Ms. Leproust, with Ms. Leproust as the chairperson of our Nominating and Governance Committee. The Board has determined that each member of our Nominating and Governance Committee meets the requirements for independence under the current Nasdaq listing standards. Our Nominating and Governance Committee is responsible for, among other things:
identifying, considering and recommending candidates for membership on our Board;
overseeing the process of evaluating the performance of our Board; and
advising our Board on other corporate governance matters.
Stock Ownership Guidelines
The Compensation Committee will periodically assess the appropriateness of stock ownership guidelines for directors and executive officers, including whether and to what extent directors and executive officers should be restricted from selling stock acquired through equity compensation.
Board and Committee Meetings and Attendance
The Board and its committees meet throughout the year on a pre-determined schedule and also hold special meetings and act by written consent from time to time. Typically, in conjunction with the regularly scheduled meetings of the Board, the independent directors meet in executive sessions outside the presence of management.
During 2023, the Board met five times (including telephonic meetings) and took action by unanimous written consent six times. During 2023, our Audit Committee met four times, our Compensation Committee met four time and took action by unanimous written consent five times, and our Nominating and Governance Committee met one time. Each director attended at least 75% of the meetings held by the Board and by each committee on which he or she served while he or she was a director during the year.
We acknowledge the value of having directors with significant experience in other businesses and activities. Effective service requires substantial commitment, but we recognize that the demands of other business activities vary substantially; therefore, we do not consider it necessary to impose specific limits on such activities so long as directors are sufficiently attentive and available to fulfill their duties and so long as directors comply at all times with our conflict of interests policies.
Director Attendance at Annual Meetings
Although we do not have a formal policy regarding attendance by members of the Board at each annual meeting of stockholders, we encourage all of our directors to attend in person, or virtually, depending on the meeting format. In fiscal year 2023, two of the directors serving at the time of last year’s annual meeting attended that meeting.

Considerations in Evaluating Director Nominees
The Nominating and Governance Committee is responsible for identifying, considering and recommending candidates to the Board for Board membership. A variety of methods are used to identify and evaluate director nominees, with the goal of maintaining and further developing a diverse, experienced and highly qualified Board. Candidates may come to our attention through current members of our Board, professional search firms, stockholders or other persons.
Our Board encourages the selection of directors who will contribute to the Company’s overall corporate goals. The Nominating and Governance Committee may from time to time review and recommend to the Board the desired qualifications, expertise and characteristics of directors, including such factors as independence, diversity, geography, financial skills and other expertise, breadth of experience, knowledge about our business and industry, willingness and ability to devote adequate time and effort to our Board, ability to contribute to our Board’s overall effectiveness, and the needs of our Board and its committees. In evaluating potential candidates for the Board, the Nominating and Governance Committee considers these factors in the light of the specific needs of the Board of Directors at that time. We value diversity on a company-wide basis but have not adopted a specific policy regarding Board diversity.

PROPOSAL NO. 1 - THE CLASS III DIRECTOR ELECTION
Our Board is divided into three classes. Each class serves for three years, with the terms of office of the respective classes expiring in successive years. Directors and director nominees in Class III will stand for election at this meeting. The terms of office of directors in Class I and Class II do not expire until the annual meetings of stockholders to be held in 2025 and 2026, respectively.
Each director will be elected by a plurality of the votes present online at the Annual Meeting or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. This means that the three individuals nominated for election to the Board of Directors at the Annual Meeting receiving the highest number of “FOR” votes will be elected. You may either vote “FOR” any of the nominees or “WITHHOLD” your vote with respect to any of the nominees. Shares represented by proxies will be voted “FOR” the election of each of the Class III nominees, unless the proxy is marked to withhold authority to so vote. You may not cumulate votes in the election of directors. If any nominee for any reason is unable to serve, the proxies may be voted for such substitute nominee as the proxy holders, who are officers of our company, might determine. Each nominee has consented to being named in this proxy statement and to serve if elected. Proxies may not be voted for more than two directors.

PROPOSAL NO. 2 - THE AUDITOR RATIFICATION
Our Audit Committee has selected Ernst & Young LLP as our principal independent registered public accounting firm to perform the audit of our consolidated financial statements for the fiscal year ending December 31, 2024. Ernst & Young LLP has served as the Company’s independent registered public accounting firm since the closing of the Business Combination, and the independent registered public accounting firm of Legacy Sema4 prior to the closing of the Business Combination. We expect that representatives of Ernst & Young LLP will be present at the Annual Meeting, will be able to make a statement if they so desire and will be available to respond to appropriate questions.
At the Annual Meeting, the stockholders are being asked to ratify the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. Although ratification by stockholders is not required by law, our Audit Committee is submitting the selection of Ernst & Young LLP to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. If this proposal does not receive the affirmative approval of a majority of the votes cast on the proposal, the Audit Committee would reconsider the appointment. Notwithstanding its selection and even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in our best interests and the interests of our stockholders.

Individual performance objectives are factored into the bonus determination as well. For the 2023 bonuses, the target annual bonuses for both Ms. Stueland and Mr. Feeley were equal to 0% of their respective annual base salaries.
18


For the 2022 bonuses, the target annual bonuses for Ms. Stueland and Mr. Feeley were equal to 100% and 50%, respectively, of their respective annual base salaries. We also awarded a discretionary bonus to Mr. Ryan in 2023 in recognition of Mr. Ryan’s contributions to the Company in 2022 and his role as our former Executive Chairman.
Equity Awards
Our company offers stock options as well as service-based restricted stock units (“RSU”s) to our named executive officers as the long-term incentive component of our compensation program. Stock options allow employees to purchase shares of our Class A Common Stock at a price per share at least equal to the fair market value of our Class A Common Stock on the date of grant and may or may not be intended to qualify as “incentive stock options” for U.S. federal income tax purposes. All of our named executive officers received RSU awards in recognition of their service to us and to further incentivize continued performance. Generally, our equity-based awards vest over four years, subject to the employee’s continued employment with us on each vesting date. In both 2023 and 2022, annual awards of RSU were made in the form of time-based awards, and time-based and performance-based awards in the case of our former Executive Chairman.
Performance-Based Equity Awards
In April 2023, we awarded Mr. Ryan 20,666 performance-based RSUs (or 682,000 RSUs before adjusting for the Reverse Stock Split) that were eligible to vest on December 31, 2023 based on the achievement of the financial performance goals applicable to our 2023 annual incentive program. The Company awarded these performance-based awards to better align the compensation of Mr. Ryan with his responsibilities in connection with the short-term performance of the Company. These performance-based RSUs were forfeited due to the established performance goals not being achieved.
In January 2022, we awarded 3,847 performance-based RSUs (or 126,980 RSUs before adjusting for the Reverse Stock Split) to Mr. Ryan that were eligible to vest on December 31, 2022 based on the achievement of certain corporate and financial objectives. These performance-based RSUs were all forfeited due to the established performance goals not being achieved. In December 2022, we awarded Mr. Ryan an additional 18,794 performance-based RSUs (or 620,177 RSUs before adjusting for the Reverse Stock Split) that were eligible to vest on December 31, 2023 based on the achievement of the financial performance goals applicable to our 2023 annual incentive program. These performance-based RSUs were forfeited due to the established performance goals not being achieved.

Licenses and Subleases
We were a party to several space license agreements and continue to be a party to sublease agreements with the Mount Sinai Health System (which we refer to together with its related entities as “Mount Sinai”) pursuant to which we leased approximately 124,000 square feet of office and laboratory space in Stamford, Connecticut for our headquarters and laboratory operations.

Commercial Relationships
Mount Sinai
We provide products and services to Mount Sinai at fair market value, including for certain oncology testing, research services and clinical data services. Mount Sinai pays for certain of these services in cash, and for other of these services in kind through performing components of collaborative research projects and/or the provision of intellectual property and data rights.
In particular, these arrangements include a data structuring and curation services agreement, dated August 1, 2019, with ISMMS and certain other Mount Sinai entities, pursuant to which we provide certain data structuring and clinical support services to Mount Sinai, including the delivery to Mount Sinai of a curated dataset and interface allowing Mount Sinai users to query the curated dataset as mutually agreed by the parties. As compensation for these services, Mount Sinai provides us certain rights to use de-identified curated data. The data structuring and curation services agreement has a five-year term and, provided we are not in default under the terms of the agreement, the agreement may be renewed at our option for up to two one-year extension periods. Following the extension periods, the agreement may be further renewed by the mutual agreement of the parties. The agreement may be terminated earlier by Mount Sinai upon certain fundamental breaches by us, by us upon a breach by Mount Sinai of its material obligations, and by either party if certain insolvency or bankruptcy events occur with respect to the other party.
We also receive products and services from Mount Sinai at fair market value, including for certain research and clinical services, development services and lab services, and licenses certain intellectual property from Mount Sinai. Pursuant to these arrangements, we made direct payments to Mount Sinai of approximately $1.3 million and $0.7 million for the years ended December 31, 2023 and 2022, respectively.
Twist Biosciences
We rely on a limited number of suppliers, one of which is Twist Biosciences Corp. (“Twist”), for certain laboratory reagents, as well as sequencers and other equipment and materials, which we use in our laboratory operations. We entered into a master supply agreement with Twist on January 24, 2023 for the purpose of the supply by Twist of these reagents, equipment and materials to us. Emily Leproust, Ph.D., a member of our Board since September 2020, has been President and Chief Executive Officer of Twist since co-founding Twist in 2013. Since October 2018, she has also served as the chair of the board of directors for Twist.

Indemnification Agreements
Our Charter contains provisions limiting the liability of directors and executive officers, and our Bylaws provide that we will indemnify each of our directors to the fullest extent permitted under Delaware law. Our Charter and our Bylaws also provide the Board with discretion to indemnify officers and employees when determined appropriate by our Board.
27


We have entered into indemnification agreements with each of our directors and executive officers and certain other key employees. The indemnification agreements provide that we will indemnify each of its directors, executive officers, and such other key employees against any and all expenses incurred by that director, executive officer, or other key employee because of his or her status as one of the Company’s directors, executive officers, or other key employees, to the fullest extent permitted by Delaware law, our Charter and our Bylaws. In addition, the indemnification agreements provide that, to the fullest extent permitted by Delaware law, the Company will advance all expenses incurred by its directors, executive officers, and other key employees in connection with a legal proceeding involving his or her status as a director, executive officer, or key employee.
Review, Approval or Ratification of Transactions with Related Parties
On July 22, 2021, we adopted a written related party transaction policy in connection with the completion of the Business Combination. The policy provides that officers, directors, holders of more than 5% of any class of our voting securities, and any member of the immediate family of and any entity affiliated with any of the foregoing persons, will not be permitted to enter into a related-party transaction with us without the prior consent of our Audit Committee, or other independent members of our Board in the event it is inappropriate for the Audit Committee to review such transaction due to a conflict of interest. Any request for us to enter into a transaction with an executive officer, director, principal stockholder, or any of their immediate family members or affiliates, in which the amount involved exceeds $120,000, must first be presented to our Audit Committee for review, consideration, and approval. In approving or rejecting the proposed transactions, our Audit Committee will take into account all of the relevant facts and circumstances available.
Director Independence
The rules of Nasdaq require that a majority of our Board be independent. An “independent director” is defined generally as a person other than an executive officer or employee of the issuer or any other individual having a relationship which, in the opinion of the issuer’s board of directors, would interfere with the exercise of independent judgement in carrying out the responsibilities of a director. Each individual serving on our Board, other than Katherine Stueland and Jason Ryan, qualifies as an independent director under Nasdaq listing standards. Each director who serves on our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee are independent under Nasdaq listing standards. See the section entitled “Corporate Governance” elsewhere in this proxy statement for more information.
SECURITY OWNERSHIP OF BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth certain information with respect to the beneficial ownership of our Class A Common Stock as of April 15, 2024, by:
each stockholder known by us to be the beneficial owner of more than 5% of our Class A Common Stock;
each of our named executive officers;

Percentage ownership of our Class A Common Stock is based on 26,141,662 shares of our Class A Common Stock outstanding on April 15, 2024. Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security or has the right to acquire a security, such as through the exercise of warrants or stock options or the vesting of RSUs, within 60 days of the date above. Shares subject to warrants or options that are currently exercisable or exercisable within 60 days of the date above or subject to RSUs that vest within 60 days of such date are considered outstanding and beneficially owned by the person holding such warrants, options or RSUs for the purpose of computing the percentage ownership of that person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person.
Except as described in the footnotes below and subject to applicable community property laws and similar laws, we believe that each person listed above has sole voting and investment power with respect to such shares. Unless otherwise noted, the address of each beneficial owner is c/o GeneDx Holdings Corp., 333 Ludlow Street, North Tower, 6th Floor, Stamford, Connecticut 06902.

HOUSEHOLDING INFORMATION
Unless we have received contrary instructions, we may send a single copy of the Notice of Internet Availability of Proxy Materials, or this proxy statement to any household at which two or more stockholders reside if we believe the stockholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce our expenses. However, if stockholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the stockholders should follow the instructions described below. Similarly, if an address is shared with another stockholder and together both of the stockholders would like to receive only a single set of our disclosure documents, the stockholders should follow these instructions:
If the shares are registered in the name of the stockholder, the stockholder should contact us at our offices at GeneDx Holdings Corp., 333 Ludlow Street, North Tower, 6th Floor, Stamford, Connecticut 06902 or by telephone at (888) 729-1206, to inform us of his or her request; or

SUBMISSION OF STOCKHOLDER PROPOSALS
Our Board is aware of no other matter that may be brought before the Annual Meeting. Under Delaware law, only business that is specified in the Notice of Annual Meeting to stockholders may be transacted at the Annual Meeting.
FUTURE STOCKHOLDER PROPOSALS
We anticipate that the 2025 annual meeting of stockholders will be held no later than June 2025. For any proposal to be considered for inclusion in the proxy statement and form of proxy for the Company’s 2025 annual meeting of stockholders, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act. Such proposals must be received by the Company at its principal executive offices a reasonable time before the Company begins to print and mail its 2025 annual meeting proxy materials in order to be considered for inclusion in the proxy materials for the 2025 annual meeting. Stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act and intended to be presented at our 2025 annual meeting of stockholders must have been received by us not later than December 30, 2024 in order to be considered for inclusion in our proxy materials for that meeting.
In addition to any other applicable requirements, for business and for nominations to be properly brought before an annual meeting by a stockholder, the Bylaws provide that the stockholder must give timely notice in proper written form to our Corporate Secretary at GeneDx Holdings Corp., 333 Ludlow Street, North Tower, 6th Floor, Stamford, Connecticut 06902, Attn: Corporate Secretary, and such business must otherwise be a proper matter for stockholder action. A stockholder’s notice to the Corporate Secretary must set forth as to each matter the stockholder proposes to bring before the annual meeting the information required by the Bylaws. Such notice, to be timely, must be received not less than 75 days nor more than 105 days prior to the first anniversary of the preceding year’s annual meeting. As a result, any notice given by or on behalf of a stockholder pursuant to these provisions of the Bylaws (and not pursuant to SEC Rule 14a-8) must be received by April 6, 2025 (but not before March 7, 2025). However, that in the event that the date of the annual meeting is advanced by more than thirty (30) days, or delayed by more than sixty (60) days, a stockholder’s notice must be so received not earlier than the one hundred and fifth (105th) day prior to such annual meeting and not later than the close of business on the later of (A) the ninetieth (90th) day prior to such annual meeting and (B) the tenth (10th) day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever first occurs. Nominations and proposals also must satisfy other requirements set forth in the Bylaws. The chairman of our Board may refuse to acknowledge the introduction of any stockholder proposal not made in compliance with the foregoing procedures and requirements set forth in the Bylaws.
