Anchor GENERAL INFORMATION

Anchor The Annual Meeting

The 2024 Annual Meeting of Stockholders (the “Annual Meeting”) of DT Midstream, Inc. (“DT Midstream,” “DTM”, the “Company,” “we,” “us” and “our”) will take place on May 10, 2024 at 9:00 a.m., Eastern Time.

This year’s annual meeting will be a completely virtual meeting of stockholders held solely through an audio webcast live over the Internet. There will be no physical meeting location. Please go to www.virtualshareholdermeeting.com/DTM2024 for instructions on how to attend and participate in the Annual Meeting. Any stockholder may attend and listen live to the webcast of the Annual Meeting over the Internet at such website. Stockholders as of the Record Date may vote and submit questions while attending the Annual Meeting via the Internet by following the instructions listed on your proxy card. The webcast starts at 9:00 a.m., Eastern Time, on May 10, 2024. We encourage you to access the meeting prior to the start time.

You may vote by telephone, over the Internet or by completing, signing, dating and returning your proxy card as soon as possible in the enclosed postage prepaid envelope.

Anchor Voting Rights

Stockholder of Record . If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company, 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 proxy. Whether or not you plan to attend the Annual Meeting virtually, we urge you to vote on the Internet or by phone or mail as instructed in the proxy card to ensure your vote is counted.

Beneficial Owner . If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of shares held in street name. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank, or other agent on how to vote the shares in your account. Your brokerage firm, bank, or other agent will not be able to vote in the election of directors unless they have your voting instructions, so it is very important that you indicate your voting instructions to the institution holding your shares. As a beneficial owner of shares, you are also invited to attend the Annual Meeting virtually. However, since 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 your broker, bank, or other agent.

Only holders of the Company’s common stock (“common stock”) as recorded in our stock register at the close of business on March 13, 2024, may vote at the Annual Meeting. On March 13, 2024, there were 97,109,100 shares of common stock issued and outstanding. Each share of common stock is entitled to one vote per share on any matter submitted to a vote of our stockholders.

Anchor Items of Business

There are three matters scheduled for a vote. The Board recommends that you vote your shares FOR each matter below:

Proposal 1: To elect seven directors from the nominees described in this proxy statement;
Proposal 2: To ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal year ending December 31, 2024; and
Proposal 3: To approve, on an advisory (non-binding) basis, the compensation of the Company’s Named Executive Officers.

TABLE OF CONTENTS

Aside from the election of directors, the ratification of the selection of our independent registered public accounting firm and the advisory vote on the compensation of the Company’s Named Executive Officers, the Company’s Board of Directors (“Board of Directors” or the “Board”) knows of no matters to be presented at the Annual Meeting. If any other matter is properly brought before the Annual Meeting, shares represented by all proxies received by the Board will be voted with respect thereto in accordance with the judgment of the persons appointed as proxies.

Anchor Voting Recommendation of the Board

The Board recommends that you vote your shares:

• “For” the election of the nominees described in the proxy statement as directors;

• “For” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal year ending December 31, 2024; and

• “For” the approval, on an advisory (non-binding) basis, the compensation of the Company’s Named Executive Officers.

Anchor How to Vote

For Proposal 1, you may vote “For All”, “Withhold All”, “For All Except” or abstain from voting with respect to each nominee to the Board. For Proposal 2, you may vote “For”, “Against” or abstain from voting. For Proposal 3, you may vote “For”, “Against” or abstain from voting. The procedures for voting are outlined below.

If you are a stockholder of record as of the Record Date, you may vote during the Annual Meeting by (i) attending the Annual Meeting virtually at www.virtualshareholdermeeting.com/DTM2024 and following the instructions, or (ii) by proxy (x) over the Internet at www.proxyvote.com, (y) by phone by calling 1-800-690-6903 or (z) by signing and returning the proxy card in the enclosed envelope. Whichever method you use, giving us your proxy means you authorize us to vote your shares at the meeting in the manner you direct. If you submit a proxy but do not specify how to vote, the Company representative named in the proxy will vote your shares in favor of the director nominees identified in this proxy statement for Proposal 1 and in favor of approving, on an advisory (non-binding) basis, the compensation of the Company’s Named Executive Officers for Proposal 3.

Whether or not you plan to attend the Annual Meeting virtually, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting virtually and vote during the Annual Meeting if you have already voted by proxy and want to change how you previously voted.

If you are a beneficial owner and hold shares through another party, such as a bank or brokerage firm, you may receive materials from them asking how you want to vote. Simply follow the instructions to ensure that your vote is counted. To vote at the Annual Meeting you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker, bank or other agent included with the notice, or contact your broker, bank, or other agent.

You may receive more than one set of proxy materials depending on how you hold your shares. Please vote all of your shares. To ensure that all of your shares are voted, for each set of proxy materials, please submit your proxy by phone, via the Internet or by signing, dating and returning the enclosed proxy card in the enclosed envelope.

Anchor Revoking a Proxy

A stockholder of record may revoke any proxy which is not irrevocable by submitting a new proxy bearing a later date, by voting by telephone or over the Internet or by delivering to the Corporate Secretary of the Company a revocation of the proxy in writing so that it is received by the Company at 500 Woodward Ave, Suite 2900, Detroit, Michigan 48226-1279 prior to the Annual Meeting.

A proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power.

If you are a beneficial owner, you may revoke your proxy by submitting new instructions to your broker, bank, or other agent, or if you have received a proxy from your broker, bank, or other agent giving you the right to vote your shares at the Annual Meeting, by attending the meeting virtually and voting during the meeting.

TABLE OF CONTENTS

Anchor Solicitation

These proxy materials are being provided in connection with the solicitation of proxies by the Company and are first being sent to stockholders on or about March 28, 2024. We have engaged Morrow Sodali LLC, which we refer to as “Morrow”, to assist in the solicitation of proxies for the Annual Meeting. We have agreed to pay Morrow a fee of $12,500. We will also reimburse Morrow for reasonable out-of-pocket expenses and will indemnify Morrow and its affiliates against certain claims, liabilities, losses, damages and expenses. In addition to these mailed proxy materials, our directors and officers may also solicit proxies in person, by telephone or by other means of communication. These parties will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

Anchor Votes Required

The vote required for Proposal 1 for the election of directors by stockholders shall be the plurality of the votes cast with respect to a director nominee. This means that the director nominees receiving the highest number of affirmative ‘for’ votes will be elected. Abstentions and “broker non-votes” (as defined below) will not count as votes either ‘for’ or ‘against’ a nominee.

Approval of Proposal 2 requires the affirmative vote of the holders of a majority of the voting power of the shares of stock present at the Annual Meeting or represented by proxy and entitled to vote on the subject matter. For Proposal 2, an abstention will have the same effect as a vote against the proposal because an abstention represents a share considered present and entitled to vote.

Proposal 3 is advisory only and will not be binding on the Company or the Board. The Organization and Compensation Committee (“O&C Committee”) values the opinions of all of our stockholders and will take into account the outcome of the vote when considering future executive compensation arrangements.

If your shares are held by a broker, the broker will ask you how you want your shares to be voted. If you give the broker instructions, your shares must be voted as you direct. If you do not give instructions for Proposal 2 to ratify selection of the Company’s independent registered public accounting firm, the broker may vote your shares at its discretion. For the remaining proposals, including the election of directors, the broker cannot vote your shares at all. When that happens, it is called a “broker non-vote.” Broker non-votes are counted in determining the presence of a quorum at the meeting, but they will have no effect on the voting for Proposals 1 and 3 because they do not represent shares present and entitled to vote.

Anchor Quorum

In order to carry on the business of the meeting, we must have a quorum. This means that the holders of record of a majority of the voting power of the issued and outstanding shares of capital stock of the Company entitled to vote at the Annual Meeting must be represented at the Annual Meeting, either by proxy or present at the virtual meeting. Once a quorum is present to organize a meeting, it shall not be broken by the subsequent withdrawal of any stockholders.

Mr. Tumminello was recently vice chair at the Interstate Natural Gas Association of America where he served as the board chair of the climate policy committee.

We believe that Mr. Tumminello’s business, operational and management expertise, including his specific experience as group president of commercial businesses for Southern Company Gas, more than 30 years of experience in the energy industry and experience serving on the boards of directors of Centrio and Renewa, provide him with the necessary experience, qualifications and skills to serve as a director of DT Midstream.

Anchor Board Meeting Quorum Requirements

Our Amended and Restated Bylaws (the “Bylaws”) provide that a majority of the total number of directors then in office will constitute a quorum.

The Board met nine times in 2023. No director attended fewer than 75% of the aggregate of the total number of Board meetings and the total number of meetings of all committees on which each such director served that were held during the period in which such director served.

We encourage our directors to attend annual meetings of stockholders and believe that attendance at annual meetings is just as important as attendance at Board and committee meetings. All of our directors attended the annual meeting in 2023.

Anchor Director Independence and Categorical Standards

As a matter of policy and in accordance with the New York Stock Exchange, which we refer to as the “NYSE”, listing standards, the Board should consist of a majority of independent directors. The Board must affirmatively determine that a director has no material relationship with DT Midstream, either directly or indirectly, or as a partner, shareholder or officer of an organization that has a relationship with DT Midstream. The Board has established the following categorical standards for director independence, which are more stringent than the NYSE independence standards:

A director for whom any of the following is true will not be considered independent:

• A director who is currently, or has been in the past three years, an employee of DT Midstream or a subsidiary.

• A director whose immediate family member is, or has been within the last three years, an executive officer of DT Midstream.

• A director who receives, or whose immediate family member receives, more than $120,000 in compensation directly from DT Midstream during any twelve-month period within the last three years, other than director and committee fees or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service).

• A director who is a current partner of a firm that is DT Midstream’s internal or external auditor; a director that has an immediate family member who is a current partner of such a firm; a director that has an immediate family member who is a current employee of such a firm and personally works on DT Midstream’s audit; or a director or immediate family member that was, within the last three years, a partner or employee of such a firm and personally worked on DT Midstream’s audit within that time.

• A director who, or whose immediate family member, is employed, or has been employed within the last three years, as an executive officer of another company where any of DT Midstream’s present executives at the same time serves or served on that company’s compensation committee.

• A director who is a current employee, or whose immediate family member is, a current executive officer, of a company that has made payments to, or received payments from, DT Midstream for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million or 2% of such other company’s consolidated gross revenues. Charitable contributions are not considered “payments” for purposes of this prohibition.

The Board has affirmatively determined, after applying these standards and considering all relevant facts and circumstances, that all of our directors other than Robert Skaggs, Jr. and David Slater qualify as independent and have no material relationship with DT Midstream. The independent directors are Angela Archon, Stephen Baker, Elaine Pickle, Peter Tumminello and Dwayne Wilson. Robert Skaggs, Jr. and David Slater are not independent directors and may be deemed to be affiliates of DT Midstream under the categorical standards. Robert Skaggs, Jr. is not considered independent due to his previous employment with the Company in the past three years. David Slater is not considered independent due to his role as President and Chief Executive Officer of DT Midstream. No material relationships exist that the Board was required to consider when determining the independence of the directors other than Robert Skaggs, Jr. and David Slater.

Anchor Executive Sessions

Independent directors meet in executive session in which independent directors meet without the presence or participation of management at most regular Board meetings and meet in executive session at other times whenever they believe it is appropriate. Stephen Baker as the Lead Independent Director chairs the executive sessions of the independent directors.

Anchor Compensation Committee Interlocks and Insider Participation

No member of our O&C Committee is presently or has been an officer or employee of the Company. In addition, during the last fiscal year, no executive officer served as a member of the compensation committee (or other Board committee performing similar functions or, in the absence of any such committee, the entire Board) of another entity, any of whose executive officers served on the O&C Committee of DT Midstream.

Anchor Director Continuing Education and Orientation

Our Governance Guidelines establish recommendations for director education. All new members of the Board are encouraged to participate in the Company’s orientation program for directors, which includes training on the Company’s structure, business policies, financial reporting and key regulatory issues. The Corporate Governance Committee evaluates the background of each new director and may, if it deems appropriate, request that the new director attend at least one director education program within one year after the date of their election. New directors also conduct visits to some of the Company’s sites of operation and have meetings with key people at the Company, including management, to help facilitate the onboarding process. As of the Record Date, all of our directors have completed the Company’s director orientation and education program. In addition, all directors are encouraged to participate in continuing education programs to enhance their skills, assist in fulfilling their responsibilities and stay current and knowledgeable about the business of the Company.

Anchor Committees of the Board

Our Board has an Audit Committee, O&C Committee, Corporate Governance Committee, Finance Committee and Environmental, Social and Governance Committee (“ESG Committee”). The Board committees act in an advisory capacity to the full Board, except that the O&C Committee has direct responsibility for the Chief Executive Officer’s goals, performance and compensation along with compensation of other executive officers, and the Audit Committee has direct responsibility for appointing, replacing, compensating and overseeing the independent registered public accounting firm. Our Board has adopted a written charter for each of the standing committees that clearly establishes the committees’ respective roles and responsibilities, which is posted to our website at dtmidstream.com/company/governance. In addition, each committee has the authority to retain independent outside professional advisors or experts as it deems advisable or necessary, including the sole authority to retain and terminate any such advisors, to carry out its duties. The Board has determined that each member of the Audit, O&C and Corporate Governance Committees is independent under our categorical standards and that each member is free of any relationship that would interfere with his or her individual exercise of independent judgment. The Board has determined that each member of the Audit Committee meets the independence requirements under the SEC rules and the NYSE listing standards applicable to audit committee members. The Board has also determined that each member of the O&C Committee meets the independence requirements under the SEC rules and the NYSE listing standards applicable to compensation committee members.

We have adopted a competitive compensation program for our non-employee directors to enable us to attract and retain high-quality directors, provide them with compensation at a level that is consistent with our compensation objectives and encourage their ownership of our shares of common stock to further align their interests with those of our stockholders. Directors who are also employees of DT Midstream do not receive any additional compensation for their services as directors.

In 2023, the Corporate Governance Committee, in consultation with Meridian Compensation Partners LLC (“Meridian”), our independent compensation consultant, and following a review of market and peer benchmark data, increased the annual cash retainer paid to our non-employee directors for their service on the Board from $80,000 to $100,000 and increased the annual equity retainer paid to our non-employee directors from $100,000 to $115,000. Additionally, the Corporate Governance Committee increased the annual cash retainer paid to the chairs of our Corporate Governance Committee, Finance Committee and ESG Committee from $10,000 to $15,000 and implemented a new annual cash retainer of $100,000 for the Chairman of the Board.

Anchor CORPORATE GOVERNANCE

Anchor Our Commitment to Sound Corporate Governance

At DT Midstream, we are committed to operating in an ethical, legal, environmentally sensitive and socially responsible manner, while creating long-term value for our stockholders. Our governance structure enables independent, experienced and accomplished directors to provide advice, insight and oversight to advance the interests of DT Midstream and our stockholders. We strive to maintain sound governance standards, as reflected in our Governance Guidelines, Code of Business Conduct and Ethics, our systematic approach to risk management and our commitment to transparent financial reporting and strong internal controls.

The following documents are available on the Corporate Governance section of our website, dtmidstream.com/company/governance, where you can access information about corporate governance at DT Midstream:

• Governance Guidelines;

• Code of Business Conduct and Ethics;

• Director Independence Standards;

• Related Party Transactions Policy;

• Corporate Policy on Political Engagement;

• Information about our confidential ethics violation reporting program, which allows DT Midstream employees and other stakeholders to identify potential instances of non-compliance or unethical practices confidentially and outside the usual management channels; and

• Information about how to communicate concerns to the Board and management.

The information on our website is not, and shall not be deemed to be, a part of this proxy statement or incorporated into any other filings we make with the SEC.

Anchor Criteria for Board Membership

We believe our Board should be comprised of directors who have had high-level executive experience, have been directors on other boards, or worked extensively with public company boards and have been tested through economic downturns and crises. Industry experience, regional relationships and broad diversity of experience and backgrounds are also factors in Board nominee selection. Although we have not adopted a formal diversity policy, we value the diversity of our Board. The Board’s Governance Guidelines confirm that we believe that it is desirable for Board members to possess diverse characteristics of gender, race, ethnicity and age, and we consider those factors in the identification and evaluation of candidates for Board membership. When determining our initial Board composition following the Spin-Off, we included diversity in our selection criteria. We believe this type of composition enables the Board to oversee the management of the business and affairs of DT Midstream effectively.

The Corporate Governance Committee considers candidates who have been properly nominated by stockholders, as well as candidates who have been identified by Board members and DT Midstream personnel. In addition, the Corporate Governance Committee may use a search firm to assist in the search for candidates and nominees and to evaluate the nominees’ skills against the Board’s criteria. Potential candidates are expected to be reviewed and evaluated by the Corporate Governance Committee, and selected candidates are expected to go on to be interviewed by one or more Corporate Governance Committee members. An invitation to join the Board is expected to be extended by the Board itself, through the Chairman of the Board and the Chair of the Corporate Governance Committee.

Under our Amended and Restated Bylaws, a group of up to 20 stockholders owning 3% or more of DT Midstream’s outstanding common stock continuously for at least three years may nominate and include in our proxy materials a candidate for the Board,

TABLE OF CONTENTS

which we refer to as a “Stockholder Nominee”, provided that the stockholder(s) and the Stockholder Nominee satisfy the requirements specified in our Amended and Restated Bylaws. The total number of Stockholder Nominees that we must include in our proxy materials in a given year shall not exceed 20% of the number of directors in office at the time of the nomination.

Anchor Board Leadership Structure

The Corporate Governance Committee routinely reviews our governance practices and board leadership structure.

Robert Skaggs, Jr. previously served as our Executive Chairman and, following his resignation as an employee of the Company, effective June 30, 2023, continues to serve as Chairman of the Board. Under our Governance Guidelines, the Board has designated Stephen Baker, a non-employee director, to serve as a Lead Independent Director when the Chairman is not independent.

In accordance with our Amended and Restated Certificate of Incorporation, our Board is currently divided into three classes as nearly equal in size as practicable. The term of the first class of directors expired upon the election of directors at our 2022 annual meeting of the stockholders; the term of the second class of directors expired upon the election of directors at our 2023 annual meeting of the stockholders and the term of the third class of directors is expiring upon the election of our directors at this Annual Meeting. Directors elected at the 2022 and 2023 annual meeting of the stockholders will hold office until the Annual Meeting. Commencing with the Annual Meeting, each director will be elected annually for a term of one year and our Board will no longer be classified.

Anchor Assessment of Board and Committee Performance

The Board evaluates its performance on an annual basis, the process of which is overseen by the Corporate Governance Committee. The evaluation is an assessment of the Board’s contribution as a whole, as well as a review of specific areas where the Board and management believe that the Board can better contribute or can better utilize more effective operational practices. In addition, each Board committee performs an annual self-assessment to determine its effectiveness. Each Board member performs an annual peer review of the other directors who have served one year or more. The results of the Board and committee self-assessments are discussed with the Board and each committee, respectively. The results of the individual peer review are reviewed by the Chair of the Corporate Governance Committee and discussed with the Corporate Governance Committee. The Chair of the Corporate Governance Committee discusses the results of the peer review with individual directors, as directed by the Corporate Governance Committee.

Additionally, the O&C Committee of the Board annually evaluates the performance of the Chief Executive Officer. The Chair of the O&C Committee discusses the results of such evaluation with the non-management directors in an executive session and communicates the results thereafter with the Chief Executive Officer. The evaluation is based on both objective and subjective criteria. Some of the factors upon which the Chief Executive Officer will be evaluated include corporate performance, development of management and the accomplishment of annual objectives and long-term strategic goals. The O&C Committee factors this evaluation when considering the compensation of the Chief Executive Officer.

Anchor Terms of Office

The Board has not established term limits for directors. We assure the independence and ongoing effectiveness of each independent director through the individualized peer assessment process described above, in which each Board member annually undergoes a rigorous evaluation by the other members. In addition, the Corporate Governance Committee of the Board has established policies that directors (other than current or retired chief executive officers of DT Midstream or our subsidiaries) shall not stand for election after attaining the age of 72 and directors who are current or retired chief executive officers of DT Midstream or our subsidiaries shall not stand for election after attaining the age of 70, in either case, unless the Board waives such age limit when circumstances exist which make it prudent to continue the service of the particular director. Except for the Chief Executive Officer and Executive Chairman, who may continue to serve as a director after retirement, any other employees who are also directors will not stand for re-election after retiring from employment with DT Midstream.

TABLE OF CONTENTS

Anchor The Board’s Role in Strategy and Succession Planning

The Board reviews the Company’s financial performance on a regular basis at Board meetings and through regular updates from management. The Board also periodically reviews and assesses the Company’s short and long-term strategy and performance, on both an absolute basis and in relation to the performance, practices and policies of its peers.

The Board also reviews the Company’s succession planning, including succession planning in the case of the incapacitation, retirement or removal of the Chief Executive Officer. In that regard, the Chief Executive Officer keeps the Board and the O&C Committee informed of management’s recommendations regarding succession plans, including through an annual report to the Board and O&C Committee on recommending and evaluating potential successors, along with a review of any development plans recommended for such individuals. The Chief Executive Officer provides to the Board, on a continuing basis, his recommendation as to a successor in the event of an unexpected emergency. The Corporate Secretary is the custodian of this confidential recommendation. The Board also reviews succession planning with respect to the Company’s other key executive officers and ensures that directors have substantial opportunities to engage with successor candidates, including emerging leaders. The Board has access to external consultants, as needed.

Anchor Board Risk Oversight Functions

Each Board committee is responsible for overseeing and considering risk issues relating to their respective committee which includes the following:

Board Committee Areas of Risk Oversight
Audit Committee Overall review of risk issues, policies and controls associated with our overall financial reporting and disclosure process and legal and regulatory compliance, and review policies on risk control assessment and financial, accounting and cybersecurity risk exposure.
Organization and Compensation Committee Assess and discuss with the Board the relationship between the inherent risks in executive compensation plans, executive compensation arrangements and executive performance goals and payouts, and how the level of risk corresponds to DT Midstream’s business strategies.
Corporate Governance Committee Review risks associated with DT Midstream’s governance practices and the interaction of DT Midstream’s governance with enterprise risk-level management.
Finance Committee Review of financial, capital, credit and insurance risk.
Environmental, Social and Governance Committee Review DT Midstream’s risk exposures as they relate to ESG matters and the management of those risks.

All Board committees meet periodically with members of senior management to discuss the relevant risks and challenges facing DT Midstream. In addition to its regularly scheduled committee meetings, the Audit Committee meets with the Chief Financial Officer, the Chief Audit Executive and Chief Risk Officer and the independent registered public accounting firm in executive sessions at least semi-annually and meets with the General Counsel and the Chief Ethics and Compliance Officer at least annually in separate executive sessions. DT Midstream’s Chief Audit Executive and Chief Risk Officer attends all Audit Committee meetings. The Chief Audit Executive and Chief Risk Officer and Chief Financial Officer meet annually with either the Audit Committee or the full Board to update the members on DT Midstream’s enterprise-level risk management. The Chief Audit Executive and Chief Risk Officer and the Chief Financial Officer also periodically meet with the other Board committees and the full Board as may be required.

We also utilize an internal Executive Committee, which is chaired by the Chief Executive Officer and is comprised of the Chief Financial Officer, Chief Operating Officer, General Counsel, Chief Administrative Officer and other senior officers. Among other things, the internal Executive Committee directs the ongoing management of a comprehensive set of enterprise level risks, including the establishment and regular review of risk migration efforts.

We believe that the committee structure of risk oversight is in the best interests of DT Midstream and our stockholders. Each committee member has expertise on risks relative to the nature of the committee on which he or she sits. The entire Board is in

TABLE OF CONTENTS

a position to assess the overall risk implications, to evaluate how they may affect DT Midstream and to provide oversight on appropriate actions for management to take. When granting authority to management, approving strategies and receiving management reports, the Board and committees consider, among other things, the risks we face.

Anchor Procedures for Approval of Related Party Transactions

Our Board has adopted a written policy regarding the review, approval and ratification of transactions with related parties as set forth in our Corporate Governance Committee Charter and the Code of Business Conduct and Ethics. This policy provides that our Corporate Governance Committee shall conduct a reasonable prior review and oversight of all related party transactions required to be disclosed pursuant to Item 404 of Regulation S-K under the Exchange Act for potential conflicts of interest and will prohibit such a transaction if it determines it to be inconsistent with the interests of DT Midstream and its stockholders. The Corporate Governance Committee shall also review such other transactions of DT Midstream in which any “related party” had, has or will have a direct or indirect material interest. In general, “related parties” are our directors, director nominees, executive officers and stockholders beneficially owning more than 5% of our outstanding common stock and immediate family members or certain affiliated entities of any of the foregoing parties. Our Corporate Governance Committee will approve or ratify only those transactions that are fair and reasonable to DT Midstream and in DT Midstream and its stockholders’ best interests.

A director may not be involved in a business transaction in which the director has a conflict of interest with DT Midstream. Anything that could present a conflict of interest for a director may also present a conflict of interest if it is related to a member of his or her immediate family. Because potential conflicts of interest may not always be clear cut, directors, individuals subject to Section 16 of the Exchange Act and senior executive officers will be expected to disclose any material transaction or relationship that involves, or may involve, a conflict of interest or potential conflict of interest with DT Midstream promptly to the chair of DT Midstream’s Corporate Governance Committee or the Chairman of the Board, who may consult with legal counsel, as appropriate.

3 Proposal: Approval, on an Advisory (Non-Binding) Basis, of the Compensation of our Named Executive Officers

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 requires the Company to provide stockholders with an opportunity to vote to approve, on an advisory basis, the compensation of our Named Executive Officers as described in the “Compensation Discussion and Analysis” (“CD&A”) section of this proxy statement and in the tabular and narrative disclosure regarding Named Executive Officer compensation, all contained under the heading “Executive Compensation” in this proxy statement.

The Company’s executive compensation program is designed to include elements of cash and equity-based compensation to motivate and reward executives who achieve short-term and long-term corporate and financial objectives leading to the success of the Company. We emphasize competitive, performance-based compensation to attract and retain talented executives and align the interests of our executives with those of our stockholders.

Our executive compensation programs have been important in driving the Company’s success in achieving its corporate and financial objectives by tying executive compensation to achieving very specific goals in each of our key priority areas.

The O&C Committee employs high standards of corporate governance when implementing and reviewing our executive compensation programs. The O&C Committee ensures independence of committee members and compensation consultants, avoids conflicts of interest and provides stockholder disclosure in accordance with SEC and NYSE requirements.

For these reasons, the Board recommends that stockholders vote in favor of the following resolution:

“RESOLVED, that the stockholders approve, on an advisory basis, the overall executive compensation paid to the Named Executive Officers of the Company, as described in the Compensation Discussion and Analysis and the tabular and narrative disclosure regarding Named Executive Officer compensation contained in this proxy statement.”

Because this vote is advisory, it will not be binding upon the Company or the Board. The O&C Committee will take into account the outcome of the vote when considering future executive compensation arrangements.

The Board recommends you vote FOR the proposal to approve executive compensation.

Anchor Compensation Discussion and Analysis

The following narratives and tables discuss the compensation paid in 2023 to our Chief Executive Officer, Chief Financial Officer and our other three most highly compensated executive officers during 2023, whom we refer to collectively as our “Named Executive Officers” or “NEOs”. Our Named Executive Officers were determined based on the compensation earned during 2023, as shown in the “Summary Compensation Table” below. Our Named Executive Officers during 2023 were:

• David Slater, President and Chief Executive Officer

• Jeffrey Jewell, Executive Vice President and Chief Financial Officer

• Christopher Zona, Executive Vice President and Chief Operating Officer

• Wendy Ellis, Executive Vice President, General Counsel and Corporate Secretary

• Melissa Cox, Executive Vice President and Chief Administrative Officer

Anchor Executive Summary

Our compensation philosophy is designed to align the interests of our executive officers with those of our stockholders by providing pay that is directly linked to the achievement of performance goals established to foster the creation of sustainable long-term stockholder value. At the root of our compensation philosophy is the use of variable, at risk compensation that connects pay outcomes with superior results and growth execution.

The Company believes in executive compensation that is competitive with our peers, has meaningful performance components and has equity-based elements to encourage executives to maintain an appropriate ownership interest in the Company. Our performance-based compensation programs result in most of the compensation of our Chief Executive Officer being linked to the achievement of a combination of short-term and long-term Company and personal goals and stockholder value creation.

TABLE OF CONTENTS

The following elements comprise the total compensation awarded to our Named Executive Officers:

Elements of Compensation How this Element Serves the Company’s Objectives
Base Salary Provides a stable, fixed source of income that reflects an executive’s job responsibilities, experience, value to the Company and demonstrated performance. The Company generally references median base salaries for our executive compensation peer group, taking into account differences in company size within the executive compensation peer group.
Annual Incentives Intended to compensate individuals yearly based on the achievement of specific near-term, annual goals, which are established at the beginning of each year and approved by the O&C Committee. The Board and management have identified several priority areas that management and the Board discuss regularly when reviewing Company performance. Our performance measures for annual incentive awards are the measurements that the Board uses to track progress in these key priority areas. Achievement of these performance objectives is a critical measure of the Company’s progress towards its goal of providing a comprehensive set of high-performing midstream pipeline, storage and gathering assets to our customers.
Long-Term Incentives Used to align executive actions with long-term management and stockholder objectives, providing rewards consistent with the creation of stockholder value. Our plan is also designed to help retain executives over time and ensure they have a strong sense of ownership in the Company.

Anchor Pay for Performance Alignment

The Company’s compensation programs are designed to clearly align performance objectives for our Named Executive Officers with the interests of stockholders and with management’s system of priorities. Our executive compensation philosophy is to motivate and reward executives who achieve short-term and long-term corporate and financial objectives leading to the success of the Company. We will continue to emphasize performance-based compensation for results that are consistent with stockholder and customer interests. The main objectives underlying this philosophy are:

• Competitive : Compensation must be competitive to attract and retain talented executives – data from peer group companies are taken into consideration when analyzing our compensation practices and levels;

• Performance-based : Compensation should have meaningful performance components – a portion of an executive’s total compensation opportunity is linked to predefined short-term and long-term corporate and financial objectives; and

• Ownership culture : Compensation must include equity-based elements to encourage executives to have an ownership interest in the Company.

Anchor What We Do and What We Don’t Do

Our compensation programs are competitive and well-governed. We adopt best practices that make sense for our Company and industry and avoid pay practices that are inconsistent with our pay-for-performance structure.

What We Do

✔ Multiple performance metrics : We use multiple performance measures in our short-term and long-term plans that link compensation to our corporate objectives and maximize stockholder value

✔ Majority of CEO pay at risk : We make the majority of compensation for our Chief Executive Officer “at risk” to further tie compensation to performance and stockholder interests

✔ Independent oversight : Our O&C Committee is comprised of all independent directors and our compensation consultant is independent

✔ Clawback Policy : We adopted a clawback policy to allow the Company to recover incentive-based compensation from our executive officers in the event of an accounting restatement

✔ Ownership guidelines : We require executives and directors to meet robust stock ownership requirements

✔ Ongoing program evaluation : We review and update our peer groups and benchmarking on a regular basis to make sure our compensation remains competitive and aligned with evolving best practices

✔ Stockholder engagement : We engage with stockholders to seek input about our compensation practices and policies

What We Don’t Do

✘ No single-trigger change-in-control payments

✘ No excessive perquisites

✘ No tax gross ups on change-in-control payments

✘ No guaranteed bonuses

✘ No hedging of Company securities for officers or directors

✘ No pledging of Company securities for officers or directors

Anchor Role of the Organization and Compensation Committee

The O&C Committee is composed entirely of independent directors, none of whom derives a personal benefit from the compensation decisions the O&C Committee makes. Generally, the O&C Committee is responsible for our overall executive total compensation philosophy, structure, practices and related risks. The O&C Committee’s responsibilities are more fully detailed in its charter. The O&C Committee continually monitors the executive compensation program and adopts changes to reflect the dynamic marketplace in which we compete for talent. To the extent necessary, the O&C Committee also works with other Board committees to review or approve reports, awards and other matters relating to compensation. In addition, the O&C Committee determines and approves the Chief Executive Officer’s compensation and approves the compensation of certain other executives.

The O&C Committee uses information from several external sources to monitor and achieve an executive compensation program that supports our business goals and attracts executives whose performance will be measured against those goals. External information enables the O&C Committee to maintain impartial decision-making regarding performance and pay. The O&C Committee annually reviews each component of the Named Executive Officers’ compensation and, based on input from management and a review of competitive data from peer group companies (as discussed below), the O&C Committee believes that the current structure is appropriately balanced and competitive to accomplish the important tasks of recruiting, retaining and motivating talented executives in the energy industry in which we compete.

TABLE OF CONTENTS

Anchor Independent Review of Compensation Program

The O&C Committee directly employs an outside consulting firm, Meridian, to advise the O&C Committee on various executive compensation matters, including current compensation trends, and to provide objective recommendations as to the design of our executive compensation program. Meridian reports directly to the O&C Committee. Use of an outside consultant is an important component of the compensation setting process, as it enables the O&C Committee to make informed decisions based on market data and practices.

A representative from Meridian attends O&C Committee meetings, meets with Committee members in executive session, consults with the members as required and provides input regarding the Chief Executive Officer’s compensation and performance.

Meridian has served as the O&C Committee’s outside consultant since July 2021. The O&C Committee annually reviews the independence of its compensation consultant and has determined Meridian to be an independent consultant. Meridian has no affiliations with any of the Named Executive Officers or members of the Board other than in its role as an outside consultant. The lead consultant and partner in charge for Meridian, who provided executive compensation consulting services to the O&C Committee, did not provide any other services to the Company during 2023.

Anchor Management’s Role

Our management works closely with the O&C Committee in the executive compensation process. Excluding the President and Chief Executive Officer’s compensation, management’s responsibilities include:

• Recommending performance measures and metrics that are formulated based on our corporate strategy and priorities;

• Reporting executive performance evaluations;

• Recommending base salary levels and other compensation, including equity awards; and

• Recommending appointment of executives.

The President and Chief Executive Officer’s compensation is determined solely by the O&C Committee, which bases its decisions on performance and market studies along with participation and recommendations from its independent outside consultant.

Anchor Executive Compensation Peer Group Assessment

Each component of executive compensation (see the section titled “Key Components of Executive Compensation” below) is compared, measured and evaluated against an executive compensation peer group of companies. The O&C Committee approves the executive compensation peer group and periodically reviews and updates the companies included in that group.

The O&C Committee reviews the executive compensation peer group annually. The 2023 executive compensation peer group was approved by the O&C Committee in August 2022. This peer group, which was applicable for compensation decisions with respect to compensation in 2023, consists of the companies listed below. The executive compensation peer group consists primarily of oil and gas storage and transportation companies, selected based on size, complexity and the quality of publicly available data with respect to these companies. The O&C Committee reviews the executive compensation peer group data when making compensation decisions relating to the Named Executive Officers and the Company’s mix of compensation components.

TABLE OF CONTENTS

The O&C Committee retained Meridian to conduct a market study covering compensation practices for similar executive officer positions in the executive compensation peer group. A market study was completed in November 2022, and the results from this market study were used by the O&C Committee as a factor in determining the compensation for our Named Executive Officers during 2023.

Anchor Key Components of Executive Compensation

The key components of the compensation program include the following:

• Base Salary;

• Annual and Long-Term Incentives;

• Retirement and Other Benefits; and

• Post-Termination Benefits

While the programs and pay levels reflect differences in job responsibilities, the structure of the compensation and benefits program is applied consistently to our Named Executive Officers, including the Chief Executive Officer. Differences in compensation between the Chief Executive Officer and the other Named Executive Officers are due, in part, to an analysis of peer group benchmark data, as well as differences in the responsibilities of each Named Executive Officer. We review each element of total compensation, both individually and on a combined basis, for each Named Executive Officer and make adjustments as appropriate based on these comparisons. The following is a more detailed discussion of the components of the Company’s executive compensation program:

Base Salary

The objective of base salary is to provide a stable, fixed source of income that reflects an executive’s job responsibilities, experience, value to the Company, and demonstrated performance. When setting individual base salary levels, we consider several factors, including (i) the market reference point for the executive’s position, (ii) the responsibilities of the executive’s position, (iii) the experience and performance of the executive, and (iv) retention issues. Market reference points target the median for most positions, adjusted to take into account differences in company size within the executive compensation peer group. In addition, we establish midpoints for each executive group level for determining base salary for those executives whose jobs cannot be easily matched in the marketplace. These midpoints are consistent with the market reference points for other executives in the same executive group. We review these midpoints annually to ensure they are consistent with the market and make salary adjustments, when appropriate.

For 2023, the O&C Committee set the annual base salary amounts for our Named Executive Officers as follows: Mr. Slater—$800,000; Mr. Jewell—$485,000; Mr. Zona—$500,000; Ms. Ellis—$420,000; and Ms. Cox—$375,000.

Annual and Long-Term Incentives

We have two primary types of incentives that reward our executives for performance. The incentives are designed to tie compensation to performance and align our executives’ interests with those of the Company’s stockholders. Our annual incentives allow us to reward executives with annual cash bonuses for performance against pre-established objectives based on work performed in the prior year. Our long-term incentives allow us to grant executives long-term equity incentives to encourage continued employment with DT Midstream and to accomplish predefined long-term performance objectives and to create stockholder alignment.

We believe the current mix among base salary, annual incentives, and long-term incentives is appropriately set to provide market-competitive compensation when Company performance warrants. The mix is more heavily weighted toward incentive compensation at higher executive levels within the Company. The interplay between the annual incentives and the long-term incentives provides a balance to motivate executives to achieve our business goals and objectives and to properly reward executives for the achievement of such goals and objectives.

TABLE OF CONTENTS

Anchor Annual Incentives

The objective of the annual incentives is to compensate individuals yearly based on the achievement of specific annual goals and tie compensation to near-term performance. In connection with the Spin-Off, we established the DT Midstream, Inc. Annual Incentive Plan (the “Annual Incentive Plan”). Under the terms of the Annual Incentive Plan, participating executives and other select employees may receive annual cash awards based on performance compared against pre-established Company, business unit and individual objectives. Objectives that management proposes are reviewed and approved or revised by the O&C Committee. The objectives include performance measures in several categories that are critical to our success. The weights, which can change from year to year, are determined based on the Company’s key priorities and areas of focus for the upcoming year. The final awards, if any, are paid after the O&C Committee approves the final results of each objective.

For 2023, the O&C Committee adopted a 2023 Annual Incentive Plan Scorecard that is determined as follows:

• The executive’s most recent year-end base salary is multiplied by a target award percentage to arrive at the target award.

• The target award is multiplied by a corporate performance modifier, ranging from 0% to 200%, that is determined based on final results compared to threshold, target and maximum levels for each objective.

• The result is the earned Annual Incentive Plan award.

Year End Salary x Target Award Percentage x Corporate Performance Modifier 0% to 200% = Earned AIP Award

Each objective has a threshold, target and maximum level. The Company must attain a minimum level of achievement for an objective before any compensation is payable with respect to that objective. The minimum established level of each objective will result in a payout of 25% of target and the maximum established for each level (or better) will result in a payment of 200% of target. The target award levels for the Named Executive Officers for 2023 were as follows: Mr. Slater, 125% of base salary; Mr. Jewell, 90% of base salary; Mr. Zona, 100% of base salary; Ms. Ellis, 75% of base salary; and Ms. Cox, 55% of base salary.

The financial performance measure, adjusted EBITDA, was chosen as an indicator of the Company’s financial strength as adjusted to align with the Company’s budget. With respect to business operations, the Operating Performance and Systems Reliability measures were chosen to enhance the Company’s operational excellence and together focus on upgrading and expanding the Company’s pipeline and construction projects. Business Development measures such as the advancement of projects, executing new business opportunities and business portfolio returns were chosen to align with stockholder interests in growing the business. Finally, certain environmental, social, governance and safety measures were included to promote the reduction of carbon emissions and other environmentally friendly practices and to ensure our Company is a safe and engaging place to work.

(1) Adjusted EBITDA reflects Company operating earnings before expenses for interest, taxes, depreciation and amortization, gains or losses from financing activities and includes the proportional share of net income (excluding interest, taxes, depreciation and amortization) from our equity method investees and excludes the proportional share of depreciation and amortization attributable to minority interests in our consolidated subsidiaries.

Business Development: 15% of the annual incentive award is based on achievement of various business development goals as approved by the O&C Committee, including maximizing available capacity, long-term contract returns, the advancement of projects, executing new business opportunities and business portfolio returns. See the table above for the payout for this performance measure.

Operating Performance: 10% of the annual incentive award is based on achievement of operational performance goals as approved by the O&C Committee, including meeting in-service timing and approved budget goals for construction and expansion projects. See the table above for the payout for this performance measure.

ESG Initiatives: 5% of the annual incentive award is based on achievement of certain environmental, social and governance goals as approved by the O&C Committee, including publishing a sustainability report and advancing our third-party certification program. See the table above for the payout for this performance measure.

Long-Term Incentives

Long-term incentives provide the O&C Committee the ability to align programs that focus on our long-term performance over a three-year period, with the objective of aligning executives’ interests with those of our stockholders. The long-term incentives are awarded under the DT Midstream, Inc. Long-Term Incentive Plan (the “DT Midstream LTIP”) and reward executives and other employees with stock-based compensation.

Our executives receive long-term incentive grants based upon a target percentage of base salary. The target award levels for the Named Executive Officers for 2023 were as follows: Mr. Slater, 575% of base salary; Mr. Jewell, 250% of base salary; Mr. Zona, 250% of base salary; Ms. Ellis, 175% of base salary; and Ms. Cox, 100% of base salary.

The value composition of the long-term incentive grants for 2023 was as follows:

Grant Type Percent of Annual Award
Performance Shares 70%
Restricted Stock Units 30%

TABLE OF CONTENTS

This mix was designed to provide incentives to executives for creating long-term stockholder value through strong financial and operating performance while also providing a portion as a time-based retention incentive.

For 2023, the O&C Committee selected performance measures that it viewed as being key drivers of the long-term financial health of the Company and generators of year-over-year stockholder value: total stockholder return (“TSR”) versus the Company’s long-term incentive plan peer group and leverage ratio. Performance is measured over the three-year period that commenced on December 31, 2022 and will end on December 31, 2025. TSR versus our long-term incentive plan peer group is calculated based on simple average stock prices in the first and last months of the performance period ( e.g. , December 2022 and December 2025). Leverage ratio is calculated as total Company net debt (including long-term and short-term debt and cash and cash equivalents and excluding debt held by unconsolidated investees) divided by adjusted EBITDA.

The long-term incentive plan peer group, which is applicable for performance-based long-term incentive compensation awards granted to our Named Executive Officers in 2023, was approved by the O&C Committee in December 2022 and consists of the companies listed below.

​ — ​ ​ — ​ ​ — ​ Long-Term Incentive Plan Peer Group — Antero Midstream Corporation MPLX, LP ​ — ​
Crestwood Equity Partners, LP ONEOK, Inc.
Energy Transfer, LP Targa Resources Corp.
EnLink Midstream Corporation TC Energy Corporation .
Enterprise Products Partners, LP Western Midstream Partners, LP
Equitrans Midstream Corporation The Williams Companies, Inc.
Kinder Morgan, Inc.

The performance objectives and the related weightings, thresholds, targets, and maximums applicable to the performance-based long-term incentive awards granted in 2021 that vested on December 31, 2023, as certified by the O&C Committee on February 15, 2024, were as follows:

Category Weight Threshold Target Maximum Result Payout Weighted Average Payout
TSR versus Peers 60% 25 th Percentile 50 th Percentile 75 th Percentile 43 rd Percentile 86.00% 51.60%

Total 131.60%
  • In millions

(1) The threshold, target and maximum leverage ratio may be adjusted annually by the Board to reflect changes in rating agency methodologies or requirements and significant strategic objectives such as acquisitions and investments. No adjustments were made to the threshold, target or maximum leverage ratio with respect to the 2023 performance shares.

Retirement and Other Benefits

Substantially all employees, including our Named Executive Officers, are eligible to participate in the DT Midstream 401(k) Plan, a tax-qualified defined contribution retirement benefit plan (the “DTM 401(k) Plan”). Our Named Executive Officers are also eligible to participate in our nonqualified defined contribution plan, the DT Midstream Supplemental Savings Plan (the “DTM Supplemental Savings Plan”).

Providing supplemental retirement and deferred compensation benefits for our executives is in keeping with our philosophy and objectives to attract and retain talented executives. The Post-Employment Benefits Tables and related footnotes beginning on page 46 describe both the tax-qualified and nonqualified retirement benefits for which certain executives are eligible and which are commonly offered by other employers in our peer groups.

TABLE OF CONTENTS

For a further description of the nonqualified supplemental retirement and deferred compensation benefits, see the section titled “Nonqualified Deferred Compensation” beginning on page 46 .

Anchor Post-Termination Agreements

We have entered into severance agreements (the “Severance Agreements”) and change-in-control severance agreements (the “Change-In-Control Severance Agreements”) with each of the Named Executive Officers. The Change-In-Control Severance Agreements are intended to provide continuity of management in the event there is a change in control of the Company and to align executive and stockholder interests in support of corporate transactions. The important terms of, and the potential payments provided under, the Severance Agreements and Change-In-Control Severance Agreements are described beginning on page 47 .

Anchor Stock Ownership Policy

In addition to the elements of executive officer compensation described above, we have adopted stock ownership guidelines pursuant to which our Named Executive Officers are required to hold a number of shares of our common stock having a market value equal to or greater than a multiple of each executive’s base salary, to be achieved within five years from entering their roles. Until the applicable ownership guideline is achieved, each Named Executive Officer is restricted from selling shares acquired from Company equity awards after payment (or withholding) of the exercise price, if applicable, and taxes. Once the applicable ownership guideline is achieved, the aforementioned restriction will no longer apply. If a Named Executive Officer’s share ownership subsequently falls back below the applicable ownership guideline and remains below the ownership guideline, the Named Executive Officer will be required to comply again with the restriction until such time as the Named Executive Officer again achieves the ownership guidelines.

Our stock ownership guidelines are shown below. All of our Named Executive Officers are in compliance with the policy.

Position Ownership Guideline as a Multiple of Base Salary
President and Chief Executive Officer 5x
Executive Vice President and Chief Financial Officer 3x
Executive Vice President and Chief Operating Officer 3x
Executive Vice President, General Counsel and Corporate Secretary 3x
Executive Vice President and Chief Administrative Officer 3x

Anchor Compensation Clawback Policy

In September 2023, the Board adopted a Clawback Policy to comply with the applicable provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules and requirements of the NYSE (including Section 303A.14 of the NYSE Listed Company Manual). In the event of an accounting restatement, under the Clawback Policy, the O&C Committee, as the committee of the Board responsible for administering the policy, is authorized to recover certain incentive-based compensation paid to an executive officer of the Company on or after October 2, 2023 to the extent such incentive-based compensation was paid on the basis of financial results in respect of any of our three most recently completed fiscal years preceding the restatement.

Anchor Internal Revenue Code Considerations

Limits on Deductibility of Compensation

Section 162(m) of the Internal Revenue Code generally places a $1 million limit on the amount of compensation a publicly held company can deduct in any tax year on compensation paid to each “covered employee” which includes our Named Executive Officers. While the O&C Committee considers tax deductibility as one of many factors in determining executive compensation, the O&C Committee will award or modify compensation that it determines to be consistent with the goals of our executive compensation program even if such compensation is not tax deductible by the Company.

TABLE OF CONTENTS

Nonqualified Deferred Compensation Programs

We have structured and intend to administer all of our nonqualified deferred compensation programs to comply with Internal Revenue Code Section 409A. Internal Revenue Code Section 409A imposes additional tax penalties on our executive officers for certain types of nonqualified deferred compensation that are not in compliance with the form and timing of elections and distribution requirements of that section.

The table below summarizes the total compensation earned by each of the Named Executive Officers for the fiscal years ended December 31, 2023, December 31, 2022 and December 31, 2021. On July 1, 2021, we consummated our Spin-Off from DTE Energy and launched as an independent publicly traded company. Although we have provided compensation information for our Named Executive Officers that predates the Spin-Off, our NEOs may not have qualified as NEOs under the prior reporting structure under DTE Energy. In 2022 and thereafter, our NEOs did not and will not receive any compensation from DTE Energy or participate in DTE Energy compensation programs, and all decisions with respect to the compensation of our NEOs are made by the O&C Committee.

Anchor PAY VERSUS PERFORMANCE

Below is information about the relationship between executive compensation actually paid (“CAP”) to our Named Executive Officers and our financial performance, as prepared in accordance with SEC rules. CAP is an amount calculated using methodology prescribed by SEC rules and differs from the compensation actually received by our Named Executive Officers and the compensation decisions described in the CD&A section above. For purposes of the Peer Group Total Shareholder Return column of the Pay Versus Performance Table, we have used the Standard & Poor’s 500 Index and Alerian Midstream Energy Index (“AMNA Index”), which we also use for purposes of the Stock Performance Graph in our annual report on Form 10-K.

(1) The following table sets forth the adjustments ( i.e. , amounts deducted and added) made to the PEO’s Summary Compensation Table Total to determine the CAP to the PEO. The valuation methodology (including assumptions) used to determine the fair value of restricted stock unit awards for purposes of determining the CAP to the Principal Executive Officer (“PEO”) is the same as set forth in footnote 2 to the Summary Compensation Table. For performance share awards, the grant date fair value of awards used for Summary Compensation Table calculations assumes target performance. To determine the year-end fair values used in the CAP calculations, we have updated the performance expectations to reflect the latest performance estimates for unvested and outstanding awards at each fiscal year end date. We have also recalculated the fair value of the Total Shareholder Return component of the performance share awards at each fiscal year end date. Furthermore, because the Qualified Plan, the SRP and the ESRP are plans controlled by DTE Energy for which the Company does not have access to or insight into the relevant compensation data, the CAP to the PEO does not include any adjustment to the actuarial present value of the PEO’s accumulated benefits under the Qualified Plan, the SRP and the ESRP, as set forth in the Summary Compensation Table. There were no DT Midstream stock awards granted prior to 2021 that vested in 2021.

(2) The amounts shown have been updated from those reported in the proxy statement filed for our annual meeting of stockholders held in 2023 to correct an administrative error. Both amounts were inadvertently understated by $ 3,000 in the annual proxy filed for our annual meeting of stockholders held in 2023.

(3) For 2023, adjusted EBITDA reflected Company operating earnings before expenses for interest, taxes, depreciation and amortization, gains or losses from financing activities and includes the proportional share of net income (excluding interest, taxes, depreciation and amortization) from our equity method investees and excludes the proportional share of depreciation and amortization attributable to minority interests in our consolidated subsidiaries.

For 2022 and 2021, adjusted EBITDA reflected Company operating earnings before expenses for interest, taxes, depreciation and amortization, gains or losses from financing activities and includes the proportional share of net income (excluding taxes, depreciation and amortization from our equity method investees) and excludes the proportional share of depreciation and amortization attributable to minority interests in our consolidated subsidiaries. If Adjusted EBITDA for 2022 and 2021 was calculated in the same manner as 2023, the results would have been $ 841 million and $ 778 million for 2022 and 2021, respectively.

(5) The following table sets forth the calculation of the average CAP to non-PEO Named Executive Officers and the adjustments ( i.e. , amounts deducted and added) made to the Summary Compensation Table Total of the relevant NEOs to determine the average CAP to the relevant Named Executive Officers. The valuation methodology (including assumptions) used to determine the fair value of equity awards for purposes of determining the average CAP to the Named Executive Officers is the same as set forth in footnote 2 to the Summary Compensation Table. For performance share awards, the grant date fair value of awards used for Summary Compensation Table calculations assumes target performance. To determine the year-end fair values used in the CAP calculations, we have updated the performance expectations to reflect the latest performance estimates for unvested and outstanding awards at each fiscal year end date. We have also recalculated the fair value of the Total Shareholder Return component of the performance share awards at each fiscal year end date. Furthermore, because the Qualified Plan, the SRP and the ESRP are plans controlled by DTE Energy for which the Company does not have access to or insight into the relevant compensation data, the CAP to the Named Executive Officers (other than the PEO) does not include any adjustment to the actuarial present value of the Named Executive Officers’ (other than the PEO) accumulated benefits under the Qualified Plan, the SRP and the ESRP, as set forth in the Summary Compensation Table. There were no DT Midstream stock awards granted prior to 2021 that vested in 2021.

(6) For purposes of our Peer Group Total Shareholder Return column of the Pay Versus Performance Table, we have used the Standard & Poor’s 500 Index (first number) and AMNA Index (second number), which we also use for purposes of the Stock Performance Graph in our annual report on Form 10-K. We believe the AMNA Index is meaningful because it is an independent, objective view of the performance of similarly sized midstream energy companies. The Total Shareholder Return values are measured from July 1, 2021, the date that DT Midstream became an independent, publicly traded company.

The following tabular list sets forth those measures, which, in our assessment, represent the three financial performance measures and the three non-financial performance measures that we use to link the compensation paid to our Named Executive Officers for fiscal year 2023 to Company performance.

Descriptions of Pay Versus Performance Relationships

The following graphs show the relationship between the CAP to our PEO and the average of the CAP to our other Named Executive Officers (other than our PEO) to our total shareholder return, the total shareholder return of our peer groups, net income and adjusted EBITDA, each over the three fiscal years ending December 31, 2021, 2022 and 2023, as reported in the table above.

For purposes of our Peer Group Total Shareholder Return, we have used both the Standard & Poor’s 500 Index and AMNA Index. We use both indexes for purposes of the Stock Performance Graph in our annual report on Form 10-K. We believe the AMNA Index is meaningful because it is an independent, objective view of the performance of similarly sized midstream energy companies. The Total Shareholder Return values are measured from July 1, 2021, the date that DT Midstream became an independent, publicly traded company.

Tax-Qualified Deferred Compensation

DTM 401(k) Plan

Following the Spin-Off, generally all DT Midstream employees are eligible to participate in the DTM 401(k) Plan. A participant may contribute up to 100% (less applicable FICA taxes and other legally required or voluntary deductions, and subject to annual limits under the Internal Revenue Code) of eligible compensation to the DTM 401(k) Plan as pre-tax, Roth, or after-tax contributions. We contribute $1 to the participant’s DTM 401(k) Plan account for each $1 the participant contributes on the first 4% of eligible compensation. We contribute $0.50 for each $1 contributed on the next 4% of eligible compensation. We also contribute 4% of eligible compensation to ensure every employee is saving for retirement, and an annual contribution of $4,000 (contributed in biweekly increments) in lieu of providing a retiree health care plan. Participants are always 100% vested in their contributions to the DTM 401(k) Plan; participants vest in our contributions to the DTM 401(k) Plan over six years of service. Service with DTE Energy before the Spin-Off is counted for purposes of vesting under the DTM 401(k) Plan.

Our contributions to the DTM 401(k) Plan are made in cash; participants may direct the investment of their contributions and our contributions to any investment option available under the DTM 401(k) Plan.

DTM Supplemental Savings Plan

Our Named Executive Officers are eligible to participate in the DTM Supplemental Savings Plan. The benefits provided under the DTM Supplemental Savings Plan include the benefits that would have otherwise been provided under the DTM 401(k) Plan, including any company contributions, but for the limitations imposed on qualified plans by the Internal Revenue Code. The percentage of compensation a participant may contribute to the DTM Supplemental Savings Plan is the same as the pre-tax percentage of compensation the participant elects to contribute to the DTM 401(k) Plan. Company contributions mirror those under the DTM 401(k) Plan, including the vesting schedule; DT Midstream may also make additional company contributions to participants’ accounts. The investment options into which a participant can elect to have the participant’s account treated as invested are the same as under the DTM 401(k) Plan.

DT Midstream maintains bookkeeping accounts for participants in the DTM Supplemental Savings Plan. A participant’s benefit will be the participant’s bookkeeping account recording the participant’s interest in each of the investment options in which the participant’s contributions and company contributions are treated as invested. No actual “contributions” are made to the investment options. Earnings and losses are calculated using the daily valuation methodology used by the recordkeeper for each corresponding investment option in the DTM 401(k) Plan.

All accounts under the DTM Supplemental Savings Plan are subject to Internal Revenue Code Section 409A. When a participant terminates employment with DT Midstream, the participant will receive the vested value of the participant’s DTM Supplemental Savings Plan account, including all of the participant’s own contributions and the vested portion of company contributions, adjusted for earnings and losses. In the event of death, a lump sum distribution will be paid to the participant’s spouse or designated beneficiary.

TABLE OF CONTENTS

Distributions from the DTM Supplemental Savings Plan will be paid in cash and made in accordance with the distribution election when the participant first became eligible to participate (or any later permissible change to the participant’s distribution election). A participant may elect to take a lump sum distribution or annual payments over a period of not less than two and not more than 15 years. Lump sum payments and initial annual installment payments from the participant’s account are made not later than March 1 of the calendar year following the calendar year in which the participant terminates employment. Certain executives, including NEOs, must wait a minimum of six months after their termination date before a distribution can be made. Subsequent annual installments are made on March 1 of each following year in the distribution period.

Anchor Potential Payments Upon Termination of Employment

All our NEOs are employees at-will and do not have employment agreements with us. We have entered into Severance Agreements and Change-In-Control Severance Agreements with certain executives, including the Named Executive Officers. The Change-In-Control Severance Agreements are intended to provide continuity of management in the event there is a change in control of the Company and to align executive and stockholder interests in support of corporate transactions.

A “qualifying termination” occurs if an executive’s employment is terminated by the Company other than as a result of the executive’s death or permanent disability or by the Company for Cause or if an executive’s employment is terminated by the executive for Good Reason (as each such term is defined in the applicable agreement), provided that with respect to the Change-In-Control Severance Agreements and the DT Midstream LTIP, an executive’s termination for Good Reason must occur during the severance period.

A “change in control” occurs if (1) we or our assets are acquired by another company or if we merge, consolidate or reorganize with or into another company and as a result of such transaction, less than 50% of the new or acquiring company’s combined voting stock is held by holders of the voting stock of the Company immediately prior to the change in control transaction, (2) a “person” becomes the beneficial owner of at least 30% of the Company’s voting stock, (3) a majority of the Company’s Board members change within a period of twelve consecutive months, or (4) the Company’s stockholders approve a complete liquidation or dissolution of the Company.

Severance Agreements

The Severance Agreements provide for severance compensation in the event that an executive experiences a qualifying termination. The severance compensation paid to an executive following a qualifying termination is equal to 100% (in the case of Mses. Ellis and Cox and Messrs. Zona and Jewell) or 200% (in the case of Mr. Slater) of (1) the executive’s base salary at the time of termination and (2) the executive’s target annual bonus under the Company’s annual incentive plan. All payments under the Severance Agreements are subject to the executive’s execution and non-revocation of a release of claims in favor of the Company.

Change-In-Control Severance Agreements

The Change-In-Control Severance Agreements provide for severance compensation in the event that an executive experiences a qualifying termination within two years after a change in control of the Company. The severance compensation paid to an executive following a qualifying termination is the same for all of the change-in-control events. The cash severance benefit is equal to a multiple of the executive’s base salary plus the greater of the executive’s annual bonus for the year in which the change in control occurs or the year in which the qualifying termination occurs, assuming target performance goals for such year would be met and that the executive’s individual performance multiplier is 100%. The multiple for all Named Executive Officers is 200%. The executive will also receive a lump sum payment equal to the greater of the executive’s target or actual annual bonus (reduced by any annual bonus otherwise paid because of the executive’s termination) for the year in which the change in control occurs or the year in which the qualifying termination occurs, assuming the executive’s individual performance multiplier is 100%, pro-rated for days worked during the calendar year in which the qualifying termination occurs. In December 2023, the Named Executive Officers’ (other than Mr. Slater) severance multiple was increased from 150% to 200% to align with industry standards informed by executive compensation peer group benchmarking conducted by Meridian.

An additional amount is paid as consideration for the prohibition against engaging in any competitive activity for the one-year period following a qualifying termination imposed by the Change-In-Control Severance Agreement. The additional amount for the Named Executive Officers is 100% of the executive’s base salary plus the greater of the executive’s actual or target annual bonus for the year in which the change in control occurs or the year in which the qualifying termination occurs, assuming target

TABLE OF CONTENTS

performance goals for such year would be met and the executive’s individual performance multiplier is 100%. In December 2023, the Named Executive Officers’ (other than Mr. Slater) restrictive covenant multiple was increased from 50% to 100% to align with industry standards informed by executive compensation peer group benchmarking conducted by Meridian.

An executive is further entitled to receive a lump sum payment equal to cost of coverage under the Company’s welfare benefit plans for the two-year period following the executive’s qualifying termination and payment by the Company for outplacement services by a firm selected by the executive in an amount up to 15% of the executive’s base salary. No payment for outplacement services will be made by the Company after the end of the calendar year following the calendar year in which an executive experiences a qualifying termination.

The Change-In-Control Severance Agreements do not provide any gross-up payments for the purposes of payment of excise taxes.

Annual Incentives

The Annual Incentive Plan provides that upon the occurrence of a change in control event described above, executives will receive payment based on the greater of the executive’s target performance level for each performance measure or the executive’s actual performance level for each performance measure, in each case for the plan year preceding the change in control and the plan year during which the change in control occurs, using performance through the date of the change in control for purposes of determining actual levels of performance. Change in control payments under the Annual Incentive Plan may not be reduced, modified or canceled.

Long-Term Incentives

The DT Midstream LTIP provides that all options, restricted stock awards, restricted stock units, performance shares and performance unit awards will become exercisable or vested or will be earned (as applicable) upon the occurrence of a change in control event described above or if the new or acquiring entity fails to replace or continue the awards. Performance shares will be based on the greater of target performance or actual performance through the change in control date. If a change in control event described above occurs and the new or acquiring entity replaces or continues the awards, all options, restricted stock awards, restricted stock units, performance shares and performance share awards will become exercisable or vested or will be earned (as applicable) as of the earlier of the date specified in the award agreement or the executive’s qualifying termination, which generally must occur within two years after the change in control date.

TABLE OF CONTENTS

Anchor Chief Executive Officer Pay Ratio

For the fiscal year ended December 31, 2023, we identified the median of all our employees, excluding our Chief Executive Officer, by using the median of Gross Pay from 2023 W-2 Box 1 Federal Taxable Wages as our consistently applied compensation measure. We reviewed gross pay for all employees who received a W-2 in 2023, whether employed on a full-time, part-time, or seasonal basis. We did not annualize the compensation for any full-time employees who were not employed by us for all of 2023.

Based on the information summarized in the table below, the ratio of the annual total compensation of our President and Chief Executive Officer to the median employee is 65 to 1. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

Because the SEC rules for identifying the median of the annual total compensation of our employees 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, the pay ratio reported by other companies may not be comparable to the pay ratio for our Company.

Anchor Certain Relationships and

Related Party Transactions

Anchor Agreements with DTE Energy

Following the Spin-Off, we and DTE Energy operate independently and neither has any ownership interest in the other. In order to govern the ongoing relationships between us and DTE Energy after the Spin-Off and to facilitate an orderly transition, we have entered into a series of agreements with DTE Energy to effect the Spin-Off, to provide a framework for the relationship between DT Midstream and DTE Energy after the Spin-Off and to provide for various services and rights and obligations following the Spin-Off, in each case, pursuant to which we and DTE Energy agree to indemnify each other against certain liabilities arising from our respective businesses. The following summarizes the terms of the material agreements with DTE Energy. The summaries of these agreements are qualified in their entirety by reference to the full text of the applicable agreements.

Separation and Distribution Agreement

We entered into a Separation and Distribution Agreement with DTE Energy that sets forth our agreements with DTE Energy regarding the principal actions taken in connection with the Spin-Off. It also sets forth other agreements that govern aspects of our relationship with DTE Energy following the Spin-Off.

Transfer of Assets and Assumption of Liabilities . The Separation and Distribution Agreement identifies certain transfers of assets and assumptions of liabilities that were necessary in advance of the Spin-Off so that we and DTE Energy retain the assets of, and the liabilities associated with, our respective businesses. The Separation and Distribution Agreement also provide for the settlement or extinguishment of certain liabilities and other obligations between us and DTE Energy. In particular, the Separation and Distribution Agreement generally provide that:

• all of the assets of the DTE Energy Midstream Business not already owned by us and owned by DTE Energy prior to the Distribution (as such term is defined in the Separation and Distribution Agreement) were transferred to us;

• all of the assets of the businesses and operations conducted by DTE Energy, other than the DTE Energy Midstream Business, not already owned by DTE Energy and owned by us prior to the Distribution were transferred to DTE Energy;

• all of the liabilities (whether accrued, contingent or otherwise) of the DTE Energy Midstream Business that were obligations of DTE Energy prior to the Distribution were assumed by us;

• all of the liabilities (whether accrued, contingent or otherwise) of the business and operations conducted by DTE Energy, other than the DTE Energy Midstream Business, that were our obligations prior to the Distribution were assumed by DTE Energy; and

• allocation of tax- and employee-related assets and liabilities were addressed separately in a Tax Matters Agreement and Employee Matters Agreement, respectively.

Internal Transactions. The Separation and Distribution Agreement describes certain actions related to the Spin-Off that occurred prior to the Distribution.

Intercompany Arrangements. All agreements, arrangements, commitments and understandings, including most intercompany accounts payable or accounts receivable, between us, on the one hand, and DTE Energy, on the other hand, were terminated or settled effective as of the Distribution, except specified agreements and arrangements that survived the Distribution.

Shared Contracts . We and DTE Energy agreed to use reasonable best efforts to cooperate to divide, partially assign, modify or replicate all agreements relating in a material respect to both the DTE Energy Midstream Business and DTE Energy’s businesses such that we shall be the beneficiary of the rights and responsible for the obligations of that portion of the agreement relating to the DTE Energy Midstream Business and DTE Energy shall be the beneficiary of the rights and responsible for the obligations of that portion of the agreement relating to DTE Energy’s businesses.

TABLE OF CONTENTS

Credit Support. We agreed to use reasonable best efforts to arrange, prior to the Distribution, for the replacement of all guarantees, covenants, indemnities, surety bonds, letters of credit or similar assurances of credit support provided by or through DTE Energy or any of its affiliates for the benefit of us or any of our affiliates, except specified credit support instruments that were intended to survive the Distribution. To the extent we were not able to replace any such credit support, we agreed, and agreed to cause any of our subsidiaries that has assumed the liability with respect to such credit support instrument, to indemnify DTE Energy for such liability.

Representations and Warranties. In general, neither we nor DTE Energy made any representations or warranties regarding any assets or liabilities transferred or assumed, the sufficiency of any such assets to operate the respective businesses, any consents or approvals required in connection with these transfers or assumptions or the Spin-Off, the value of, or freedom from any lien or other security interest in, any assets transferred, the absence of any defenses relating to any claim of either party or the legal sufficiency of any conveyance documents. Except as expressly set forth in the Separation and Distribution Agreement, all assets were transferred on an “as is,” “where is” basis.

Further Assurances. The parties agreed to use reasonable best efforts to effect any transfers contemplated by the Separation and Distribution Agreement that were not consummated prior to the Distribution as promptly as practicable following the Distribution Date (as such term is defined in the Separation and Distribution Agreement). In addition, the parties agreed to use reasonable best efforts to effect any transfer or re-transfer of any asset or any assumption of liability that was improperly transferred or retained as promptly as reasonably practicable following the Distribution.

The Distribution. The Separation and Distribution Agreement governs DTE Energy’s and our respective rights and obligations regarding the Distribution. Prior to the Distribution, DTE Energy delivered all the issued and outstanding shares of our common stock to the distribution agent. Following the Distribution Date, the distribution agent electronically delivered the shares of our common stock to DTE Energy shareholders based on the distribution ratio.

Exchange of Information. We and DTE Energy have agreed to provide each other with information reasonably necessary to comply with reporting, disclosure, filing or other requirements of any national securities exchange or governmental authority, for use in judicial, regulatory, administrative and other proceedings and to satisfy audit, accounting, litigation and other similar requests. We and DTE Energy also agreed to use reasonable best efforts to retain such information in accordance with our respective record retention policies as in effect on the date of the Separation and Distribution Agreement. Each party also agreed to use its reasonable best efforts to assist the other with its financial reporting and audit obligations for an agreed period of time.

Release of Claims. We and DTE Energy agreed to release the other and its affiliates, successors and assigns, and all persons that prior to the Distribution were the other’s shareholders, directors, officers, members, agents and employees, and their respective heirs, executors, administrators, successors and assigns, from any claims against any of them that arise out of or relate to events, circumstances or actions occurring or failing to occur or any conditions existing at or prior to the time of the Distribution. These releases are subject to exceptions set forth in the Separation and Distribution Agreement.

Indemnification. We and DTE Energy agreed to indemnify the other and each of the other’s former and current directors, officers and employees, and each of the heirs, executors, successors and assigns of any of them, against certain liabilities incurred in connection with the Spin-Off and our and DTE Energy’s respective businesses. The amount of either DTE Energy’s or our indemnification obligations will be reduced by any insurance proceeds the party being indemnified receives. The Separation and Distribution Agreement also specifies procedures regarding claims subject to indemnification.

Transition Services Agreement

We entered into a Transition Services Agreement pursuant to which DTE Energy provides us with specified services for a limited time to help ensure an orderly transition following the Distribution. The services to be provided include certain accounting, tax, legal, human resources, information technology, investor relations, treasury, federal affairs, environment and safety, gas operations, other shared facilities and other general, administrative and operational services.

The Transition Services Agreement specifies the calculation of our costs for these services. The agreed upon charges for such services are generally intended to allow the service provider to recover all costs and expenses of providing such services. The cost of these services may not necessarily be reflective of prices that we could have obtained for similar services from an independent third party.

TABLE OF CONTENTS

The Transition Services Agreement terminates on the expiration of the term of the last service provided under it, which will be no longer than 24 months following the Distribution Date. We and DTE Energy are each generally able to terminate a particular service prior to its scheduled expiration date in the event of the other party’s uncured material breach with respect to such service, and we may terminate one or more services to be provided under the Transition Services Agreement for convenience, subject generally to a minimum notice period of 30 or 90 days, depending on the original length of service.

We have agreed to indemnify DTE Energy and each of its former and current directors, officers and employees, and each of the heirs, executors, successors and assigns of any of them from any liabilities to the extent arising out of DTE Energy’s provision of the services unless such damages are the result of DTE Energy’s breach of the Transition Services Agreement, violation of law or third-party rights, gross negligence or willful misconduct in providing services. The cumulative liability of DTE Energy in its capacity as service provider under the Transition Services Agreement is limited to the aggregate amount paid to it for services under such agreement.

Tax Matters Agreement

We entered into a Tax Matters Agreement with DTE Energy that governs the respective rights, responsibilities and obligations of DTE Energy and us after the Spin-Off with respect to all tax matters (including tax liabilities, tax attributes, tax returns and tax contests).

The Tax Matters Agreement generally provides that we will indemnify DTE Energy for any taxes resulting from the failure of any step of the Spin-Off or the Internal Transactions to qualify for its intended tax treatment under U.S. Federal income tax laws, if such taxes result from (1) untrue representations or breaches of covenants that we made and agreed to in connection with the Spin-Off, (2) the application of certain provisions of U.S. Federal income tax law to the Spin-Off, including Section 355(e) of the Code, or (3) any other action or omission that we knew or reasonably should have expected would give rise to such taxes. DTE Energy has the exclusive right to control the conduct of any audit or contest relating to these taxes, but is not permitted to settle any such audit or contest without our consent (which we may not unreasonably withhold or delay).

With respect to taxes other than those incurred in connection with the Spin-Off, the Tax Matters Agreement generally provides that we will indemnify DTE Energy for any taxes of ours or our subsidiaries for all periods, except to the extent such taxes are reported on tax returns for a consolidated, combined, unitary or other group that includes DTE Energy or any of its subsidiaries. As a member of DTE Energy’s consolidated U.S. Federal income tax group, we have (and continue to have following the Spin-Off) joint and several liability with DTE Energy to the IRS for the consolidated U.S. Federal income taxes of the DTE Energy group relating to the taxable periods in which we were part of the group.

The Tax Matters Agreement imposes certain restrictions on us (including restrictions on share issuances and repurchases, business combinations, sales of assets and similar transactions) that are designed to preserve the tax-free nature of the Spin-Off. These restrictions apply for the two-year period after the Spin-Off. Under the Tax Matters Agreement, these restrictions apply unless we obtain an opinion from counsel or a ruling from the IRS (in each case satisfactory to DTE Energy) or obtain consent from DTE Energy. These restrictions may limit our ability to pursue strategic transactions that may maximize the value of our business, and might discourage or delay a strategic transaction that our stockholders may consider favorable.

Employee Matters Agreement

We entered into an Employee Matters Agreement with DTE Energy that addresses certain employment, compensation and benefits matters, including the allocation and treatment of certain assets and liabilities relating to our employees and compensation and benefit plans and programs in which our employees participated in prior to the Spin-Off. In connection with the Spin-Off, we provide compensation and benefit plans and programs in which our employees participate going forward.

Ongoing Commercial Agreements

In addition to the above agreements, we are also currently party to various other agreements with DTE Energy and its subsidiaries, including certain pipelines, gathering and storage services and operating and maintenance agreements, that continue subject to their existing terms or terms and conditions to be negotiated and agreed to. We do not consider these agreements to be material to DTE Energy and its subsidiaries.

Other Arrangements

Prior to the Spin-Off, we have had various other arrangements with DTE Energy, including arrangements whereby DTE Energy performed various corporate functions for us, such as accounting, auditing, communications, tax, legal and ethics and compliance program administration, human resources, information technology, insurance, investor relations, risk management, treasury, other shared facilities and other general, administrative and limited operational functions.

As described in more detail in the section above entitled “Separation and Distribution Agreement” these arrangements, other than those contemplated pursuant to the Transition Services Agreement, were generally terminated in connection with the Spin-Off. We do not consider these arrangements with DTE Energy to be material.

Anchor Related Party Transactions

Robert Skaggs, Jr., a member of our Board of Directors, also serves on the DTE Energy Board and may be required to recuse himself from deliberations relating to these arrangements and other arrangements between us and DTE Energy in the future, due to potential conflicts of interest.

Anchor Stockholder Proposals for the

2025 Annual Meeting of

Stockholders

Stockholders who, in accordance with Rule 14a-8 of the Exchange Act, wish to present proposals at our 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”) and wish to have those proposals included in the proxy materials to be distributed by us in connection with our 2025 Annual Meeting must submit their proposals to the Company at Corporate Secretary, 500 Woodward Ave, Suite 2900, Detroit, Michigan 48226-1279 on or before November 28, 2024. Any such proposal must meet the requirements set forth in the rules and regulations of the SEC, including Rule 14a-8, in order for such proposal to be eligible for inclusion in our 2025 proxy statement.

In accordance with our Bylaws, in order to be properly brought before the 2025 Annual Meeting, regardless of inclusion in our proxy statement, notice of a matter a stockholder wishes to present, including any director nominations, must be delivered to the Company at Corporate Secretary, 500 Woodward Ave, Suite 2900, Detroit, Michigan 48226-1279, not less than 90 nor more than 120 days prior to the first anniversary date of this year’s annual meeting, which would be no earlier than January 10, 2025 and no later than February 9, 2025. If, however, the date of the meeting is advanced by more than 30 days, or delayed by more than 60 days, from the anniversary date of this year’s annual meeting, notice by the stockholder to be timely must be delivered not earlier than 90 days prior to the 2025 Annual Meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or 10th day following the day on which public announcement of the date of such meeting is first made by us. The stockholder must also provide all of the information required by our Bylaws.

Anchor Householding

The SEC allows companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Householding is the term used to describe the practice of delivering a single set of notices, proxy statements and annual reports to any household at which two or more stockholders reside. This procedure reduces the volume of duplicate information stockholders receive and also reduces a company’s printing and mailing costs. Householding will continue until you are notified otherwise or you submit contrary instructions.

The Company will promptly deliver an additional copy of any such document to any stockholder who writes the Company. Alternatively, if you share an address with another stockholder and have received multiple copies of our notice, proxy statement and annual report, you may contact us to request delivery of a single copy of these materials. Any such written request should be directed to the Company at Corporate Secretary, 500 Woodward Ave, Suite 2900, Detroit, Michigan 48226-1279.

Anchor Annual Report on Form 10-K

A copy of our annual report on Form 10-K for the year ended December 31, 2023, as filed with the SEC, will be provided to stockholders without charge upon written request directed to Investor Relations, 500 Woodward Ave, Suite 2900, Detroit, Michigan 48226-1279 or by email at [email protected]. The Company makes available on or through our website free of charge our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to such reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after filing.
