Fellow Shareholders,

On behalf of the Board of Directors and management of Equitrans Midstream Corporation, I am pleased to invite you to participate in our annual meeting of shareholders on Tuesday, April 25, 2023, at 9:00 a.m. (ET), to be held virtually via live webcast at www.virtualshareholdermeeting.com/ETRN2023. By continuing to hold our Annual Meeting virtually, our shareholders are able to participate from any location, providing a cost savings to both us and our shareholders while contributing to our sustainability efforts by reducing the environmental impact of our annual meeting.

Equitrans Midstream is one of the largest natural gas gatherers in the United States and holds a significant transmission footprint in the Appalachian Basin and our common stock is traded on the New York Stock Exchange under the symbol “ETRN.” Your continued interest in and support of our Company is invaluable and receiving shareholder feedback is instrumental to our future success.

This year you will be asked to vote on several items at the annual meeting, including the election of directors, approval of our executive compensation program for 2022 (the say-on-pay vote) and ratification of the appointment of our independent registered public accounting firm for 2023. The proxy statement describes these items in more detail. Your vote is important — please read the proxy materials and follow the voting instructions to ensure your shares are represented at the meeting.

Whether or not you plan to participate in the annual meeting, please vote as soon as possible — by telephone, via the Internet, or by completing and signing your paper proxy card or vote instruction form — to ensure that your shares are represented and voted.

Our mission is simple — to provide safe, reliable, sustainable, and innovative infrastructure solutions for the energy industry. The principles that guide our behaviors and decisions are based on our five core values: safety, integrity, collaboration, transparency, and excellence. With these values in mind, we will continue to work diligently to:

➢

Create value for our shareholders

➢

Provide an engaging workplace for our employees

➢

Preserve and protect the environment

➢

Support the communities where we live and work

Natural gas is not only the heart of our business, but also a critical component of the global energy portfolio. The reality is that natural gas will remain an indispensable link to continuing to provide clean, affordable, and reliable energy for decades to come. Further, continued natural gas production and infrastructure growth are directly supportive of our nation’s energy security. Even as more renewable energy infrastructure is installed, energy demand is projected to continue to grow and our country and the world will continue to rely on natural gas as we pursue the goal of achieving a lower-carbon future. As an energy infrastructure company, we are driving environmental, social and governance initiatives across our business on many fronts, and we are excited for the future of the natural gas industry as we continue to work to provide reliable energy for the long term. I look forward to reporting on our initiatives and many successes, most particularly our efforts to further enhance our sustainability performance.

Thank you for your investment in Equitrans Midstream Corporation and your participation in our annual meeting of shareholders.

Thomas F. Karam​

Chairman and Chief Executive Officer

ANNUAL MEETING

Time and Date:	9:00 a.m. (Eastern Time) on Tuesday, April 25, 2023

VIRTUAL ANNUAL MEETING

We will be holding our 2023 annual meeting of shareholders solely via webcast in order to enable shareholders to participate from any location, to provide cost savings to both us and our shareholders, and to reduce the environmental impact of our annual meeting. We remain sensitive to concerns regarding virtual meetings generally from investor advisory groups and other shareholder rights advocates that have voiced concerns that virtual meetings may diminish shareholder voice or reduce accountability. Accordingly, we have designed the procedures for our virtual meeting format to enhance, rather than constrain, shareholder access, participation and communication, allowing a shareholder to participate fully and equally from any location at no cost to the shareholder. For example, the online format allows shareholders to communicate with us during the meeting so they can ask appropriate questions of our Board of Directors or management in accordance with the rules of conduct for the meeting and the format also allows shareholders to vote electronically. See “Participating in the Annual Meeting” for additional information.

GOVERNANCE HIGHLIGHTS

BUSINESS HIGHLIGHTS

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) HIGHLIGHTS

The Company recognizes that the long-term interests of shareholders are served by managing ESG matters important to the Company’s stakeholders and working to be resilient and appropriately positioned in any environment, including a lower-carbon economy. The Company embraces working to conduct business in a socially responsible and ethical manner by respecting all stakeholders and is focused on identifying and executing on ESG and sustainability initiatives while further integrating corporate responsibility and ESG concerns into its business strategy and decision-making throughout the organization.

iv   Equitrans Midstream Corporation – 2023 Proxy Statement

COMPENSATION HIGHLIGHTS

The Human Capital and Compensation Committee (Compensation Committee) of the Company’s Board of Directors adopted a compensation philosophy and exercises oversight with respect to programs and practices that seek to (i) align total direct compensation (TDC) for our named executive officers (NEOs) using market comparables and other relevant factors; and (ii) deliver transparency and fairness to shareholders, employees and other stakeholders while encouraging sound business strategy and execution that leads to long-term and sustainable shareholder value. At our 2022 annual meeting, our say-on-pay proposal received support from more than 97% of our shares voted, leading the Compensation Committee to believe our compensation programs and practices have strong shareholder support. The primary components of our 2022 compensation program were:

*

See Appendix B for important information regarding the non-GAAP financial measures Economic Adjusted EBITDA (defined below) and free cash flow.

The compensation program is designed to provide an appropriate mix of fixed and variable pay to encourage retention and promote creation of long-term and sustainable shareholder value. The program is weighted towards variable pay that requires the Company to achieve well defined performance metrics in order for NEOs to realize performance-based annual and long-term incentives. The charts below reflect the fixed and at-risk components of the 2022 compensation for (i) Mr. Karam, our Chief Executive Officer, and (ii) our other NEOs. The amounts for each component of TDC set forth in the charts below were calculated in accordance with Securities and Exchange Commission (SEC) rules. TDC, which is not

Equitrans Midstream Corporation – 2023 Proxy Statement   v

a substitute for the total compensation as reported in the Summary Compensation Table or the Pay Versus Performance disclosure on pages 45 and 56, respectively, of this proxy statement, omits certain other compensation (e.g., 401(k) contributions and perquisites) that is reflected in the Summary Compensation Table. For additional information, including information regarding how total compensation is calculated under SEC rules, see the footnotes accompanying the Summary Compensation Table.

IMPORTANT DATES FOR 2024 ANNUAL MEETING OF SHAREHOLDERS

Shareholder proposals submitted for inclusion in Equitrans Midstream’s 2024 proxy statement under SEC rules must be submitted in writing and received by Equitrans Midstream’s Corporate Secretary on or before November 3, 2023.

Under Equitrans Midstream’s Fifth Amended and Restated Bylaws (the Bylaws), if a shareholder would like to present a matter not included in Equitrans Midstream’s proxy statement in person at the 2024 annual meeting of shareholders, including nominations for director candidates, advance notice must be submitted in writing and received by Equitrans Midstream’s Corporate Secretary no earlier than the close of business on December 27, 2023, and no later than the close of business on January 26, 2024. Shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees under Rule 14a-19 under the Exchange Act must comply with the requirements of the Company’s Bylaws, including providing the notice required under Rule 14a-19 by January 26, 2024 and complying with the requirements of Rule 14a-19 and Sections 1.09 and 1.10 of the Company’s Bylaws. The Company will disregard any proxies solicited for a shareholder’s director nominees if such shareholder fails to comply with such requirements.

Under Equitrans Midstream’s proxy access Bylaws provision, a shareholder, or group of twenty or fewer shareholders, owning continuously for at least three years as of both the date the notice is received by us and the record date for the annual meeting, shares of Equitrans Midstream representing an aggregate of at least 3% of the voting power entitled to vote in the election of directors, may nominate and include in Equitrans Midstream’s proxy statement director nominees constituting the greater of  (i) two and (ii) 20% of the Board of Directors of Equitrans Midstream provided that such nominations are submitted in writing and received by our Corporate Secretary no earlier than the close of business on October 4, 2023 (the 150th day prior to the first anniversary of the date that the Company mailed its proxy statement for the prior annual meeting) and no later than the close of business on November 3, 2023 (the 120th day prior to the first anniversary of the date that the Company mailed its proxy statement for the prior annual meeting).

For additional information, see “Additional Information — Shareholder Proposals and Director Nominations” on page 68 of this proxy statement.

vi   Equitrans Midstream Corporation – 2023 Proxy Statement

ITEM NO. 1 — ELECTION OF DIRECTORS

The Board of Directors recommends a vote FOR each nominee for the Board of Directors.

Our Board of Directors, sometimes referred to in this proxy statement as the Board or our Board, is presenting eight nominees for election as directors at our annual meeting. All nominees currently serve on our Board of Directors and their current terms will expire at the 2023 annual meeting. Mses. Vicky A. Bailey, Sarah M. Barpoulis, and Diana M. Charletta, and Messrs. Kenneth M. Burke, Thomas F. Karam, D. Mark Leland, Norman J. Szydlowski, and Robert F. Vagt, have been nominated to serve for a term of one year to expire at the 2024 annual meeting, or until their earlier removal or resignation or a successor is duly elected and qualified. Each nominee consents to being named in this proxy statement and to serve if elected. The Board has no reason to believe that any nominee will be unavailable or unable to serve. If any nominee is unable to stand for election for any reason, then the shares represented at our annual meeting will be voted by the persons named as proxies for substitute nominees proposed by the Board, unless the Board decides to reduce its size.

Ms. Collawn currently serves on the Board, as well as on another public company board and serves as Chairman and Chief Executive Officer of PNM Resources, Inc. (PNM). While the Board recognizes the general governance concern regarding the number of boards upon which an individual director may sit, the Board has evaluated Ms. Collawn’s service under its Corporate Governance Guidelines and believes that there are no accountability concerns with respect to Ms. Collawn as she has attended 100% of the Board and committee meetings required and continues to be a very involved and valuable member of the Board. However, given the anticipated effect of the application of formulaic “overboarding” policies which may provide for low shareholder support, as was the case at the 2022 annual meeting of shareholders, and not because of any disagreement with the Company or any of its affiliates, Ms. Collawn has determined not to stand for re-election to the Board when her term expires at the 2023 annual meeting. In connection with Ms. Collawn not standing for re-election, the Board intends to reduce its size to eight members. The Board further intends to re-elect Ms. Collawn to the Board should PNM’s publicly announced, pending merger combination with Avangrid, Inc. be completed and Ms. Collawn steps down as Chairman and Chief Executive Officer of PNM in connection with the transaction closing.

The Board, following the recommendation of the Corporate Governance Committee, selected our eight nominees based on a review of the attributes discussed on page 16 under “Corporate Governance and Board Matters — Director Nominations.” Our Board believes that the nominees, individually and as a whole, possess qualifications consistent with our desired attributes and are providing and will continue to provide management with strong independent oversight as we implement our strategic objectives.

Each of our director nominees brings a unique skillset to the Board of Directors. Notably, all eight of our director nominees are experienced in Energy, Regulatory, Utility and/or Government, with seven of our directors having experience in the fields of finance, accounting and/or audit and internal control, and prior experience on the boards of other publicly traded companies.

Equitrans Midstream Corporation – 2023 Proxy Statement   1

In addition, certain of our directors have experience in a number of significant areas of focus of the Company, including climate-related experience, based on managerial experience or derived through their board service. The following charts provide an overview of the attributes represented on our Board of Directors by our director nominees, in addition to each director nominee’s competencies included in the director profiles on the following pages.

Experience reflects education, board and/or managerial derived experience in cybersecurity, water-related, climate-related or energy transition opportunities.

Each nominee must be elected by a majority of the votes cast FOR that director’s election, and votes may not be cumulated. The persons named as proxies will vote FOR the nominees named, unless you vote against, or abstain from voting for or against, one or more of them.

2   Equitrans Midstream Corporation – 2023 Proxy Statement

In addition, under our Bylaws, each nominee has submitted an irrevocable conditional resignation to be effective if the nominee receives a greater number of votes against than votes FOR his or her election in an uncontested election. If this occurs, the Board will decide whether to accept the tendered resignation no later than 90 days after certification of the election. The Board’s determination shall be made without the participation of any nominee whose resignation is under consideration with respect to the election. The Board’s explanation of its decision will be promptly disclosed on a Form 8-K furnished to the SEC.

CORPORATE GOVERNANCE AND BOARD MATTERS

Board Meetings and Committees

The Board currently has four standing Committees: Audit, Human Capital and Compensation, Corporate Governance, and Health, Safety, Sustainability and Environmental. The Board may from time to time form new Committees, disband an existing Committee and delegate additional responsibilities to a Committee. Our Committees report on their activities to the Board on a routine basis and also make recommendations regarding matters to be approved by the Board. The responsibilities of the Committees are included in written charters, which are reviewed at least annually by the Committees and the Board. All charters may be viewed on the Company’s website at www.equitransmidstream.com by clicking on “About” on the main page and then on “Governance.”

In 2022, the Board made certain adjustments to its Committees in connection with areas of increasing Board focus. In April 2022, the Board renamed the Health, Safety, Security and Environmental Committee, the Health, Safety, Sustainability and Environmental (HSSE) Committee to highlight the Company’s emphasis on, and the importance of, sustainability, as well as the committee’s role in providing oversight of a large number of sustainability matters. Additionally, in April 2022, the Board elected to exercise direct oversight, rather than acting through the HSSE and Audit committees, of information technology and cybersecurity matters given the increasing importance of such matters. Similarly, in July 2022, the Board renamed the Management Development and Compensation Committee, the Human Capital and Compensation Committee and amended its charter to highlight the scope of its responsibilities beyond compensation to encompass other key factors which influence our human capital programs relevant to our workforce, including workplace health and wellness, talent attraction and retention, pay equity, diversity and inclusion, corporate culture and employee engagement initiatives.

The Company does not have a formal policy of requiring its directors to attend the annual meeting, but the Company encourages them to do so. All of our directors participated in the 2022 annual meeting.

In 2022, our Board held 11 meetings, with regular communication between meetings, and each of our directors serving on the Board during 2022 attended at least 95% of the aggregate meetings of our Board and the Committees on which he or she served. The following charts summarize each Committee’s primary responsibilities, membership and number of meetings held in 2022.

Compensation Process

In discharging the Board’s responsibilities relating to compensation of the Company’s executive officers, the Compensation Committee recommends, and the Board approves, the target TDC for NEOs by establishing base salaries and setting short-term (bonus) and long-term incentive targets. This process includes consideration of the items discussed in more detail in the section titled “Compensation Discussion and Analysis — Determination of Target Total Direct Compensation (TDC)” below. When appropriate, the Compensation Committee also provides certain limited perquisites and other benefits to executive officers and other key employees.

The Compensation Committee, with the approval of the Board, approves the plan designs and performance metrics for all of the Company’s short-term and long-term incentive programs. The Compensation Committee also sets target and maximum metrics and related payouts under the Company’s programs for executive officers and reviews the appropriateness of these for all other Company personnel. After completion of the performance period, the Compensation Committee reviews actual performance in comparison to established metrics to determine the amount of short-term and long-term incentive awards earned for each executive officer and for other Company personnel in total.

With respect to the compensation program for 2022, the Compensation Committee retained the services of Mercer (US) Inc. (Mercer) as its independent consultant to aid the Compensation Committee in performing its duties. Representatives of Mercer provided the Compensation Committee with market data and counsel regarding executive officer compensation programs and practices, discussed in more detail in the section titled “Compensation Discussion and Analysis” below. Representatives of Mercer did not make recommendations on, or approve, the amount of compensation for any executive officer. On August 25, 2022, following a request for proposal process in the ordinary course of business, the Compensation Committee approved the engagement of Pay Governance LLC (Pay Governance) and Pay Governance served as the Committee’s independent compensation consultant for the remainder of 2022. The Company has affirmatively determined that no conflict of interest arose or has arisen in connection with the work of Mercer or Pay Governance as compensation consultant for the Compensation Committee.

The Company’s compensation process includes discussions among the members of the Compensation Committee, other independent directors of the Board, management and the compensation consultant. The Compensation Committee always seeks approval of the Board with respect to the total direct compensation for each executive officer.

Certain executive officers may review information with the Compensation Committee during meetings and may present management’s views or recommendations. During 2022, our executive team occasionally consulted with Willis Towers Watson, its own compensation consultant, when developing its views or recommendations regarding executive compensation matters. The Compensation Committee evaluates these recommendations including, if desired, in consultation with its independent compensation consultant, and takes them into consideration when making the Compensation Committee’s decisions and recommendations. When establishing TDC for executive officers and reviewing actual performance against established metrics, the Compensation Committee considers the CEO’s compensation recommendations. The CEO does not participate in Compensation Committee or Board deliberations about his compensation.

The Compensation Committee has delegated limited authority to Mr. Karam, in his capacity as a director of the Company, to issue special bonus payments and grant certain long-term incentive awards under the Equitrans Midstream Corporation 2018 Long-Term Incentive Plan (as amended, the ETRN LTIP). These awards must follow established guidelines, are reviewed by the Compensation Committee on a quarterly basis, and include New Hire, CEO, Retention, Discretionary New Hire Awards and, beginning January 1, 2023, Promotion Awards.

The Compensation Committee has approved a pre-established basket to provide for off-cycle New Hire awards pursuant to the following guidelines:

➢

Individuals hired after the annual grant date who would have qualified for a grant may be awarded restricted shares or units prorated, based upon the long-term incentive program target for the position. Under this limited authorization, individual grants may not exceed $75,000.

12   Equitrans Midstream Corporation – 2023 Proxy Statement

The Compensation Committee has also approved a pre-established basket to provide for CEO Awards, Retention Awards, and Discretionary New Hire Awards to individuals pursuant to the following guidelines:

➢

CEO Awards are for the purpose of recognizing individual performance as follows:

◦

Individuals who have received ETRN LTIP grants as part of the annual award cycle are eligible to receive cash awards limited to $20,000 per employee per grant.

◦

Individuals who have not received ETRN LTIP grants as part of the annual award cycle are eligible to receive ETRN restricted units, cash or any combination thereof with the award value limited to $20,000 per employee per grant.

➢

Retention Awards are for the purpose of addressing compensation for key personnel who have been offered employment outside the company with more favorable equity-based compensation arrangements. Individual grants may not exceed $25,000.

➢

Discretionary New Hire Awards consisting of restricted stock units may be made to newly hired employees not otherwise entitled to a New Hire award discussed above on the condition that no award exceeds $25,000 per employee per grant.

Beginning January 1, 2023, the Compensation Committee gave Mr. Karam the authority to grant prorated equity awards, based on the long-term incentive program target for the position, for employees who are newly promoted into long-term incentive program eligible roles, up to a maximum of  $75,000 per award.

Named executive officers (and prior to January 1, 2023, direct reports of the CEO) are not eligible for awards under Mr. Karam’s delegated authority described above.

The Compensation Committee has not delegated its authority to award equity to any other executive officer.

We provide additional information regarding the Compensation Committee and the Company’s policies and procedures regarding executive compensation below under “Compensation Discussion and Analysis.”

Board Leadership Structure

As described in the Company’s corporate governance guidelines, the Board of Directors believes that the functions of the Chairman of the Board are distinct from those of the CEO but that both functions may be effectively performed by the same individual. From time to time, generally in connection with succession planning, the Board will consider whether the Chairman and the CEO should be separate, and if separate, whether the Chairman should be an outside director or an inside director. In July 2019, the Board concluded that combining the functions of Chairman and CEO was the most effective leadership structure for the Company and appointed Mr. Karam as the Chairman of the Board. The Board reaffirmed its conclusion in April 2022 and, based on a recommendation of the Corporate Governance Committee, reappointed Mr. Karam as Chairman of the Board for a term expiring at the Board’s 2023 annual meeting. The Board believes the present structure provides the Company and the Board with strong leadership, while promoting appropriate

➢

independent oversight of management, with a strong Lead Independent Director in Mr. Vagt and a board structure that is 78% independent. In addition, a combined Chairman and CEO allows the Company to communicate its business, strategy and value to shareholders, investors, employees, other stakeholders, regulators and the public with a single voice.

Under the Company’s corporate governance guidelines, when the Board does not have an independent Chairman, the Board must designate an independent director as the Lead Independent Director. The Lead Independent Director’s exclusive duties are described in the box on this page.

A Lead Independent Director’s term is generally for one year, but an individual may serve multiple consecutive terms as the Lead Independent Director if recommended by the Corporate Governance Committee and approved by the Board.

In April 2022, the Board, based on a recommendation from the Corporate Governance Committee, re-elected Mr. Vagt to serve as Lead Independent Director of the Board for a one-year term. Mr. Vagt has held this position since the Separation.

Board’s Role in Risk Oversight

The Company faces a variety of risks, including operational, financial, strategic, and reputational risks. The Board, acting as a whole and through its committees, oversees the Company’s processes for assessing and managing these risks, while management is responsible for the day-to-day management of these risks. Board oversight is conducted primarily through the Audit Committee’s oversight of the Company’s process for assessing major risk exposures and the policies management has implemented to monitor and control such exposures, which includes the Company’s utilization of its Enterprise Risk Committee (ERC), which is a cross functional team of senior management that is responsible for the identification and evaluation of risks. The Board annually reviews the Company’s enterprise risks identified by management. Board oversight also is conducted through the HSSE Committee’s oversight of health, safety, sustainability and environmental risks, and also through the other committees of the Board, as appropriate. In fulfilling its risk oversight role, the Board must consider whether the risk management processes designed and implemented by our management are adequate and functioning as designed to identify our risk exposures and to elevate major and emerging risks for discussion at the Board level.

With the oversight of the Board, our management team has implemented practices, processes and programs designed to identify a broad range of risks that affect the Company, their probability and severity, and to help manage the risks to which the Company is exposed. Through the ERC, the Company uses a structured and systematic approach to identify and evaluate risks with potential to have a financial or strategic impact on the business, which results are reported to the Board. The ERC identifies and evaluates risks based on likelihood, impact, mitigation effectiveness, velocity/time horizon, inherent risk, and residual risk.

In furtherance of the Board’s oversight responsibilities and the Company’s day-to-day management of risk, Company management meets as needed with external advisors to discuss risks applicable to the Company and obtains perspectives which inform management’s discussions with the Board.

The Board

➢

Reviews the major risks facing the Company and delegates oversight of certain major risks to applicable Board Committees

➢

The Company’s Risk Manager, with support from the Strategic Planning and IT teams, facilitates ERC meetings to evaluate new or previously identified risks, their classifications, and emerging or impactful issues or events.

➢

The Risk Manager also reports periodically to the Board or designated Board committees regarding the status of enterprise risk management activities, including the results of periodic risk assessments

Director Nominations

The responsibilities of the Corporate Governance Committee include identifying and recommending to the Board for approval the requisite skills and characteristics to be found in individuals who will serve as members of the Board. The Committee strives to ensure that the Board consists of individuals from diverse educational and professional experiences and backgrounds who, collectively, provide meaningful counsel to, and effective oversight of, management. The Corporate Governance Committee reviews the qualifications and backgrounds of the directors, as well as the overall composition of the Board, and recommends to the Board for approval the slate of directors to be recommended for nomination for election at the Company’s annual meeting of shareholders.

When assessing new director candidates for nomination, regardless of who recommends the candidate for consideration, the Corporate Governance Committee will consider the background, diversity, personal characteristics and business experience of the candidate against the ideal attributes identified below.

During 2022, our management team spent a significant amount of time meeting with and speaking to our shareholders. We welcome feedback from our shareholders and strive to maintain the best governance, compensation and oversight practices.

Sustainability and Corporate Responsibility

We embrace working to conduct business in a socially responsible and ethical manner. We believe that our continued focus and execution on ESG and sustainability initiatives over time will serve to distinctly position us and create value. We aim to operate with integrity, accountability and transparency by respecting all

20   Equitrans Midstream Corporation – 2023 Proxy Statement

stakeholders, and are focused on identifying and executing on ESG and sustainability initiatives while further integrating corporate responsibility and ESG concerns into our business strategy and decision-making throughout the organization. We have highlighted below certain important steps that we have taken to further communicate, structure, and embed within our operations our sustainability practices.

➢

Continued Enhanced Transparency Through Sustainability Reporting.   In 2022, we published our third annual corporate sustainability report (CSR), in accordance with the most recent set of Global Reporting Initiative (GRI) Universal and Topic Standards, as well as GRI’s Oil and Gas Sector Standards, and the Sustainability Accounting Standards Board (SASB) Oil & Gas — Midstream Standards. Our 2022 CSR highlights our top-tier ESG topics and external stakeholder engagement. Our 2022 CSR builds and expands on our 2021 CSR by leveraging inputs from internal and external stakeholders and supplemental sources, including GRI, SASB, industry associations, agencies and various sustainability frameworks in order to identify and report on the ESG topics that we believe are most significant to our business and stakeholders. As a result of our review of this input, we identified public policy and regulatory relations, water management, security/cybersecurity, and waste management as important ESG topics, which we reported on as material topics for the first time. The 2022 CSR also outlined our continued success during 2021 in improving our environmental, health, and safety metrics, including progress made during such period towards our commitment to reduce methane emissions from our natural gas pipeline assets and other initiatives to reduce greenhouse gas emissions (GHG) from our operations, as well as enhanced our discussion of ongoing social programs and policies, including those relevant to our human capital management.

In 2022, we also submitted and received a score of  “B” for our first voluntary CDP Water Security Questionnaire response, which includes data from our comprehensive evaluation of our water sourcing, usage and consumption. We also received an improved score of  “B” on our second CDP Climate Change Questionnaire response, through which we provided additional transparency about our climate governance, strategy, risks, and opportunities. Providing this information to our investors, customers, and other stakeholders demonstrates our focus on mitigating our climate impact-related matters and preparing for the transition to a lower-carbon economy. Additionally, in 2022, we completed a Task Force on Climate-related Financial Disclosure (TCFD) readiness assessment, in which we prepared a gap analysis as the first step in our efforts toward implementing this global standard on ESG reporting.

➢

Clear Board and Executive Oversight of Sustainability and Corporate Responsibility.   Our Board of Directors, acting through its committees, oversees our policies, programs, and strategies related to corporate social responsibility and sustainability, including ESG matters and related risks and opportunities, such as those related to climate change, and regularly receives reports from our Chief Sustainability Officer (CSO) and broader management. In April 2022, the Board renamed the Health, Safety, Security and Environmental Committee the Health, Safety, Sustainability and Environmental Committee to highlight the Company’s emphasis on, and the importance of, sustainability, as well as the committee’s role in providing oversight of a large number of sustainability matters. Additionally, in 2022 we modified our executive oversight structure such that our CSO reports directly to the Chief Executive Officer of the Company, thereby further elevating our continued internal focus on, and underscoring our belief on the importance of, ESG and sustainability efforts. Our management-level Enterprise Risk Committee is responsible for reviewing, prioritizing and addressing our major risk exposures and considering new or emerging risks, including related to ESG. In 2022, we continued to utilize our management-level ESG Committee and ESG Working Groups (with the addition of a water-focused working group) to help implement and manage the day-to-day efforts and actions related to material ESG and sustainability topics. The ESG Working Groups are directly overseen by our CSO through the ESG Committee.

We consider sustainability-focused risks and opportunities in establishing our strategic and capital spending processes. For example, in support of our published climate policy and GHG reduction goals, in 2022 we made investments to replace gas-driven pneumatics with instrument air systems and high-bleed pneumatic devices with low- or intermittent-bleed controllers to reduce methane emissions relative to 2019 baseline levels. Further, our new compressor station designs employ reduced methane emission strategies such as non-venting shutdowns, compressed air pneumatics, electric motor dehydration pumps, and vent gas recovery to suction. We expect to continue to pursue strategic sustainability initiatives as appropriate, including in respect of climate change.

➢

Publication of Our Environmental Justice Policy.   In July 2022, we adopted our Environmental Justice Policy, which we believe is an important step taken in addition to our initial Climate Policy, and other

Equitrans Midstream Corporation – 2023 Proxy Statement   21

policies and statements that outline our commitment to incorporating sustainability throughout our operations, including our Human Rights Policy, Supplier Code of Conduct, Stakeholder Engagement and Community Investment Plan, and a Biodiversity Statement. Our Environmental Justice Policy focuses on incorporating environmental justice principles and community feedback in our project planning including through meaningful community engagement, targeted outreach to tribal and indigenous communities, environmental justice-focused training and measuring progress toward environmental justice goals. In furtherance of such initiatives, in October 2022 our Board and senior management participated in environmental justice training.

➢

Continuing to Link Compensation to Meaningful Safety and Sustainability Goals.   Building on our continued emphasis of safe operations — above all else — and the Company’s continued efforts to institutionalize its commitment to and pursuit of achievement of ESG and sustainability initiatives and recognizing shareholders’ and other stakeholders’ continued focus on ESG and sustainability matters, particularly in respect of climate change, the Compensation Committee determined to increase the focus on sustainability metrics in the 2022 short-term incentive program (STIP), in which all employees, including executives, participate. First, the Compensation Committee determined to again include a methane emissions mitigation metric, which provided that the Company undertake and complete certain projects to achieve targeted methane emissions mitigation. Second, the Compensation Committee added a new sustainability metric reflecting the Company’s timely completion and submission of the voluntary CDP Water Security Questionnaire response, which included a comprehensive water inventory. To further enhance the Company’s safety performance culture, the Compensation Committee utilized the Safety Proactivity Rate, which is based in part on the previously utilized Incidents with Serious Potential rate and takes into account observations with serious potential, and has a target that resets each quarter, which the Compensation Committee believes rewards sustained performance and promotes continued focus on safe operations throughout the entire year.

➢

Founding member of newly formed Appalachian Methane Initiative (AMI).   In January 2023, the Company, along with Chesapeake Energy Corporation and EQT Corporation, formed AMI, a coalition committed to further enhancing methane monitoring throughout the Appalachian Basin and facilitating additional methane emissions reduction in the region. AMI’s efforts are intended to promote greater efficiency in the identification and remedy of potential fugitive methane emissions from operations in the Appalachian Basin through coordinated satellite and aerial surveys on a geographic-basis, as opposed to an operator-specific basis, while taking into account advanced methane monitoring and reporting frameworks. Additionally, the coalition will seek to coordinate and share best practices in mitigating methane emissions from natural gas operations, including production and midstream, and collaborate on activities and monitor results through transparent, publicly available reporting.

More information regarding our sustainability initiatives is available on our website (www.equitransmidstream.com) by selecting the “Sustainability” tab on the main page. Information included on our website, including the CSR, CDP Climate Change Questionnaire Response, and other ESG reports, and any other policies or codes, is not incorporated into this proxy statement.

Director Independence

The NYSE listing standards and our governance documents require a majority of our directors and each member of our Audit, Compensation and Corporate Governance Committees to be independent. For a director to be considered independent, the Board must annually determine that he or she has no material relationship with the Company except as a director. To assist it in determining director independence, the Board established guidelines that meet or exceed the independence requirements under the NYSE listing standards. These corporate governance guidelines may be found on the Company’s website at www.equitransmidstream.com by clicking on “About” on the main page and then on “Governance.”

The Board considers all relevant facts and circumstances in making an independence determination. Any relationship involving a Company director that complies with the independence standards included in the Company’s corporate governance guidelines and is not otherwise a related person transaction under the Company’s related person transaction approval policy (the related person transaction policy) is deemed to be an immaterial relationship not requiring consideration by the Board in assessing independence. In the first quarter of 2023, our Board, in coordination with our Corporate Governance Committee, made an independence determination for each of our directors and affirmatively determined that all our directors are independent, other than Mr. Karam and Ms. Charletta.

22   Equitrans Midstream Corporation – 2023 Proxy Statement

Director ownership of Company stock is encouraged and is not in itself a basis for determining that a director is not independent, provided that such ownership may preclude participation on the Audit Committee if its magnitude is sufficient to make the director an affiliated person of the Company as described in the Audit Committee charter. See “Equity-Based Compensation” under the caption “Directors’ Compensation” below for a description of the stock ownership guidelines for directors.

Review, Approval or Ratification of Transactions with Related Persons

Our Board has adopted a related person transaction policy. Under the policy, it is the responsibility of the Corporate Governance Committee to conduct a prior review of Related Person Transactions (as defined below) not otherwise approved by the independent members of the Board. Company management, with the assistance of the Company’s legal department, is responsible for determining whether a transaction between the Company and a Related Person (as defined below) constitutes a Related Person Transaction. This determination is based on a review of the facts and circumstances regarding the transaction, including information provided in annual director and executive officer questionnaires. If it is determined that a transaction is a Related Person Transaction that has not been approved by the Board, the material facts regarding the transaction are reported to the Corporate Governance Committee for its review. The Corporate Governance Committee, or in certain cases the Chair of the Corporate Governance Committee followed by a report to the Corporate Governance Committee, determines whether to approve, revise, reject, or take other action with respect to the Related Person Transaction.

Under the related person transaction policy, a Related Person Transaction is generally a transaction in which the Company or a subsidiary is a participant, the amount involved exceeds $120,000, and a Related Person has a direct or indirect material interest in the transaction. A Related Person is generally any person who is a director or executive officer of the Company, any nominee for director, any shareholder known to the Company to be the beneficial owner of more than 5% of any class of the Company’s voting securities, and any immediate family member (as defined by the SEC) of any of the foregoing persons.

Under the policy, the following transactions are deemed to be automatically pre-approved and do not need to be brought to the Corporate Governance Committee for individual approval:

➢

transactions involving employment of an executive officer by the Company, as long as the executive officer is not an immediate family member of another executive officer or director of the Company and the compensation paid to the executive officer was approved by the Compensation Committee;

➢

transactions involving compensation and benefits paid to a director for service as a director of the Company;

➢

transactions on competitive business terms with another company in which the only relationship of a director or immediate family member of a director is as (i) an employee or executive officer, (ii) a director, or (iii) a beneficial owner of less than 10% of that company’s shares, provided that the aggregate amount involved does not exceed the greater of  $1,000,000 or 2% of the other company’s consolidated gross revenue;

➢

transactions where the interest of the Related Person arises solely from the ownership of a class of equity securities of the Company, and all holders of that class of equity securities receive the same benefit on a pro-rata basis (e.g., payment of dividends);

➢

transactions where the rates or charges involved are determined by competitive bids;

➢

transactions involving the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental regulation;

➢

transactions involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services; and

➢

charitable contributions, grants or endowments by the Company or the Company’s charitable foundation to a charitable or non-profit organization, foundation or university in which a Related Person’s only relationship is as an employee or a director or trustee, if the aggregate amount involved does not exceed the greater of  $1,000,000 or 2% of the recipient’s consolidated gross revenue.

The related person transaction policy does not limit or affect the application of the Company’s code of business conduct and ethics and related policies, which require directors and executive officers to avoid engaging in any

Equitrans Midstream Corporation – 2023 Proxy Statement   23

activity or relationship that may interfere, or have the appearance of interfering, with the performance of the directors’ or executive officers’ duties to the Company. Such policies require all directors and executive officers to report and fully disclose the nature of any proposed conduct or transaction that involves, or could involve, a conflict of interest and to obtain approval before any action is undertaken.

Related Person Transactions with Directors and Executive Officers

No reportable transactions between the Company and any of its directors or executive officers occurred during 2022, and there are no such proposed transactions.

Related Person Transactions with EQT

A discussion of related person transactions with EQT is attached on Appendix A to this Proxy Statement. Based solely on information reported by EQT in a Schedule 13G/A filed with the SEC on April 28, 2022, EQT was no longer a related party of the Company as of April 22, 2022.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee has served as an officer or employee of Equitrans Midstream at any time. During 2022, no Equitrans Midstream executive officer served as a member of the compensation committee or on the board of directors of any company at which a member of Equitrans Midstream’s Compensation Committee or Board of Directors served as an executive officer.

DIRECTORS’ COMPENSATION

The Corporate Governance Committee reviews and the Board approves director compensation on an annual basis. No compensation is paid to employee directors for their service as directors. The Corporate Governance Committee engaged Mercer to review director compensation for 2022. Mercer performed a review of the compensation paid to our non-employee directors relative to the Compensation Peer Group (defined below) and a group of industry peer companies identified by Mercer. In light of the non-employee directors’ roles and responsibilities and after considering director compensation at relevant peer group companies, Mercer recommended the following non-employee director cash and equity-based compensation, which was approved by our Board for the 2022 calendar year.

Compensation Feature	​
Annual cash retainer — Board member	$100,000
Annual cash retainer — Committee Chair	Audit: $20,000 Compensation: $20,000 All other Committees: $15,000
Annual cash retainer — Committee member (excluding the Chair)	Audit: $7,500 Corporate Governance, Compensation, HSSE: None
Annual retainer — Chairman of the Board and Lead Independent Director	Chairman: $0 Lead Independent Director: $25,000
Deferred stock units	Value equal to $150,000

Equity-Based Compensation

The Company grants to each non-employee director, on an annual basis, stock units under the ETRN LTIP, the payouts of which are deferred under Equitrans Midstream’s Amended and Restated Directors’ Deferred Compensation Plan (the Director Plan). Each deferred stock unit vests upon award and will be payable upon termination of service as a director of Equitrans Midstream. Each deferred stock unit is equal in value to one share of Equitrans Midstream common stock and does not have voting rights. The deferred stock unit awards are automatically deferred into the Director Plan, and dividends thereon are credited quarterly in the form of additional deferred stock units.

Newly elected non-employee directors of Equitrans Midstream are generally expected to receive an equity grant upon joining the Board equal to the pro-rata amount of the then applicable annual grant.

Deferred Compensation

The Company maintains the Director Plan. Under the Director Plan, in addition to the automatic deferral of deferred stock unit awards, non-employee directors are permitted to elect to defer up to 100% of their retainers and any fees into the Director Plan and receive an investment return on the deferred funds as if the funds were invested in Company common stock or permitted mutual funds. Prior to the deferral, plan participants are required to irrevocably elect to receive the deferred funds either in a lump sum or in equal annual installments. Deferred funds for which directors have elected to receive an investment return as if the funds were invested in Company common stock will be distributed in shares of Company common stock. Distributions will be made or, if applicable, commence following termination of service as a director. The directors’ deferred compensation accounts are unsecured obligations of the Company. Mr. Szydlowski and Ms. Collawn deferred fees under the Director Plan during 2022.

Equitrans Midstream Corporation – 2023 Proxy Statement   25

Stock Ownership Guidelines

The non-employee directors are subject to stock ownership guidelines which require them to hold shares (or share equivalents, including deferred stock units) with a value equal to five times the annual cash retainer. Under the guidelines, directors have up to five years from joining the Board to acquire a sufficient number of shares (or share equivalents, including deferred stock units) to meet the stock ownership guidelines. Each of the Company’s non-employee directors satisfies the stock ownership guidelines or is within the five-year grace period.

Other

➢

All directors are eligible to participate in the Matching Gifts Program of the Equitrans Midstream Foundation on the same terms as Company employees. Under this program, the Equitrans Midstream Foundation will match gifts of at least $100 made by a director to eligible charities, up to an aggregate total of  $50,000 per director in any calendar year.

➢

The Company reimburses directors for their travel and related expenses in connection with attending Board and Committee meetings and related activities. The Company also provides non-employee directors with $20,000 of life insurance and $250,000 of travel accident insurance while traveling on business for the Company.

30   Equitrans Midstream Corporation – 2023 Proxy Statement

Executive Summary

COMPENSATION
PHILOSOPHY AND
OVERVIEW ➢
The Human Capital and Compensation Committee (for purposes of this CD&A, the Committee) functions independently from management in overseeing compensation programs and practices. ​ ➢
The compensation program includes three key elements (base salary, annual incentives and long-term incentives) and seeks to align total direct compensation (TDC) for our NEO positions with our Compensation Peer Group (defined below) using market comparables and other relevant information. ​ ➢
The program is designed to pay for performance and is weighted towards variable pay which requires the Company to achieve well-defined performance metrics in order for NEOs to realize performance-based annual and long-term incentives. ​ ➢
Except as set forth below under the sections “Health Benefits” and “Limited Perquisites,” retirement and other benefit programs are the same for all employees and executive perquisites are limited. ​ ➢
The program delivers transparency and fairness to shareholders, employees and other stakeholders while encouraging sound business strategy and execution that leads to long-term and sustainable shareholder value. ​

COMPANY
HIGHLIGHTS IN
2022 ➢
Delivered 2022 net cash provided by operating activities of approximately $846 million and 2022 Free Cash Flow (defined below) of approximately $380 million. ​ ➢
Recorded 71% of total operating revenue from firm reservation fees. ​ ➢
Furthered our progress in developing our sustainability program and reporting by completing our first voluntary CDP Water Security questionnaire, for which we received a grade of  “B.” ​ ➢
Building upon our methane emissions mitigation aspirations and efforts in such respect in 2021, set a compensation goal for the 2022 Executive Short-Term Incentive Plan (ESTIP) related to undertaking and completing certain projects to achieve targeted methane emissions mitigation, which resulted in an 8.04% annualized reduction in methane emissions relative to 2019 amounts (including Eureka Midstream Holdings, LLC (Eureka Midstream) and excluding the Mountain Valley Pipeline (MVP)). ​ ➢
Developed and implemented a “Safety Proactivity Rate,” which is designed to be used as a component of the health, safety, sustainability and environmental (HSSE) performance metric under the 2022 ESTIP, to incentivize continuing proactive, Company-wide focus on safety efforts each quarter throughout 2022, and, regarding safety, observed a 73% increase in departments participating in observations related to safety concerns and realized two peer-to-peer and two remote worker observations with serious potential. ​ ➢
Achieved a Days Away, Restricted or Transferred (DART) rate reduction year-over-year of 73%, which is approximately 4% better than the national average and approximately 50% better than the industry average. ​ ➢
Completed an EQM Midstream Partners, LP (EQM) senior notes offering in June 2022 resulting in net proceeds of approximately $984.5 million, which was primarily used to repay outstanding indebtedness under other tranches of EQM senior notes, improving the Company’s debt maturity schedule. ​ ➢
Began mixed-use water system buildout, including commencing operations of the first above ground storage facility. ​

Equitrans Midstream Corporation – 2023 Proxy Statement   31

HOW DID WE PAY
OUR NEOS
IN 2022? ➢
Made adjustments where appropriate to our NEOs’ fixed and incentive pay opportunities as merited by the Committee’s evaluation of the executive’s performance and evaluation of competitive pay practices. ​ ➢
Retained our historical annual incentive program design under our ESTIP reflecting financial and HSSE metrics. ​ ➢
Amounts earned under the 2022 plan year for the ESTIP were based on achievement of three performance metrics: Economic Adjusted EBITDA (defined below), Free Cash Flow and HSSE metrics. The 2022 ESTIP payout was 161% of target, which was an approximately 5 percentage point lower payout than the ESTIP metrics nominally provided for in 2022 in connection with the ongoing investigation of the Rager Mountain incident (defined and more fully explained below). See “2022 ESTIP Performance — Rager Mountain Natural Gas Storage Field Incident” for further information. The awards will be paid in early 2023. ​ ➢
Continued to provide long-term incentive opportunities to our NEOs, and maintained the performance portion of our program focusing solely on the Company’s Relative TSR versus our TSR Peer Group (defined below) over a three-year period. ​ ➢
A payout of 19.1% was earned under the Equitrans Midstream Corporation 2020 Performance Share Unit Program (the 2020 PSUP), the performance period for which ended on December 31, 2022. ​ ➢
We did not pay any discretionary bonuses to our NEOs in 2022. ​

This CD&A, the “Narrative Disclosure to Summary Compensation Table”, the “2022 Grants of Plan-Based Awards Table” and the “Pay Versus Performance” disclosure contain references to 2022 Adjusted EBITDA, 2022 Economic Adjusted EBITDA and Free Cash Flow, financial measures that have not been calculated in accordance with U.S. generally accepted accounting principles (GAAP), which also are referred to as non-GAAP supplemental financial measures. Attached as Appendix B are reconciliations of 2022 Adjusted EBITDA, 2022 Economic Adjusted EBITDA and Free Cash Flow to 2022 Company net income and net cash provided by operating activities, respectively, the most directly comparable GAAP financial measures, as well as other important disclosures regarding non-GAAP financial measures.

Compensation Philosophy and Practices

In designing the 2022 compensation structure, the Committee utilized the following guidelines as the foundation for the program:

➢

The program should aid in the recruitment and retention of management and key personnel.

➢

The program should encourage sound business strategy and execution that leads to long-term shareholder value.

➢

The program should establish key elements of compensation (base salary, annual short-term incentive and long-term incentive targets) that approximate the 50th percentile of the Company’s Compensation Peer Group’s TDC amounts.

➢

The program should ensure all short-term incentives and the majority of long-term incentives are performance-driven based on Company-wide, well-defined metrics and should avoid individual metrics or subjective judgments in determining payments.

➢

The program should limit executive perquisites to basic programs that are minimal in amount and number and are consistent with market practices.

➢

The program should promote and reward a culture of integrity, safety and collaboration and seek to emphasize favorable ESG behavior.

➢

The program should be transparent and take into account the distinct interests of shareholders, stakeholders and employees.

➢

The Committee should receive periodic feedback from management to assess the program’s effectiveness in supporting the Company’s business objectives.

32   Equitrans Midstream Corporation – 2023 Proxy Statement

In addition to what we do and do not do, we maintain the following compensation policies to provide accountability to our Company and our shareholders.

How We Determine Executive Compensation

Our Compensation Program is Based on Three Key Elements of Compensation

The Company’s compensation program is based on three key elements of compensation:

➢

base salary

➢

annual short-term incentives (ESTIP)

➢

long-term incentives (LTIP)

Each element is determined with a view toward offering competitive TDC versus similar peer group positions while also providing compensation levels that aid in the retention of high-performing executives. The following table describes each element and outlines the Committee’s objectives in using each element of compensation.

Compensation Element	Description	Objectives
Base Salary	Fixed compensation that is reviewed annually and is based on performance, experience, responsibilities, skillset and market value.	➢ Provide a base level of compensation that corresponds to position and responsibilities. ➢ Attract, retain, reward and motivate qualified and experienced executives.
Annual Short-Term Incentive Program (ESTIP)	“At-risk” compensation measured against clearly-defined annual financial and operational goals, including Economic Adjusted EBITDA, HSSE metrics & Free Cash Flow.	➢ Incentivize executives to achieve near-term goals that ultimately contribute to long-term Company growth and shareholder returns.
Long-Term Incentive Program (LTIP)	Mix of long-term target compensation consisting of PRSUs and time-based RSAs. In 2022, PRSUs were granted and may be earned at zero to 200 percent of target units based on three-year TSR vs. an established performance peer group. RSAs subject to three-year cliff vesting.	➢ Align executives’ interests with those of Company shareholders. ➢ Promote stability among leadership via incentives to remain with the Company long-term. ➢ Incentivize executives to achieve goals that drive Company performance and shareholder value over the long-term. ➢ Pay-for-performance structure that results in no payout for PRSUs in the event of poor relative performance versus peers.

A majority of our NEO compensation is at-risk and is issued in the form of both short- and long-term incentives. Individuals in a position to influence the growth of shareholder wealth have larger portions of their total compensation delivered in the form of equity-based long-term incentives. The charts below reflect the fixed and at-risk elements of the 2022 compensation for (i) Mr. Karam, our Chief Executive Officer (CEO), and (ii) our other NEOs. The amounts for each component of TDC set forth in the charts below were calculated in accordance with SEC rules. TDC, which is not a substitute for the total compensation as reported in the Summary Compensation Table or the Pay Versus Performance disclosure on pages 45 and 56, respectively, of this proxy statement, omits certain other compensation (e.g., 401(k) contributions and perquisites) that is reflected in the Summary Compensation Table. For additional information, including information regarding how total compensation is calculated under SEC rules, see the footnotes accompanying the Summary Compensation Table.

34   Equitrans Midstream Corporation – 2023 Proxy Statement

Determination of Target Total Direct Compensation (TDC)

For 2022, the Committee developed the target TDC for our NEOs by establishing base salaries and setting annual and long-term incentive targets which were then recommended to, and approved by, the Board.

When establishing target TDC for each NEO, the Committee considered:

➢

the compensation philosophy and practices articulated above;

➢

the market median target compensation elements of the Company’s Compensation Peer Group as developed by the Committee in consultation with Mercer, its independent compensation consultant for 2021 and a portion of 2022;

➢

the scope of the executive’s responsibility, internal pay equity, succession planning and industry-specific technical skills and abilities that may be difficult to replace;

➢

the CEO’s compensation recommendations (with respect to NEOs other than the CEO); and

➢

input from the other independent directors of the Board.

In evaluating the amount and type of each component of compensation, the Committee considers the effect of each element on all other elements, as well as the allocation of target TDC between fixed and at-risk pay and cash and equity. The Committee is committed to providing that a significant portion of each NEO’s TDC opportunity take the form of performance-based awards that only pay out upon attainment of performance goals that drive Company results over the long-term. This strong pay for performance alignment is reflected in the amounts earned by our NEOs based on the achievement of metrics established by the Committee under the ESTIP and LTIP program. The following charts illustrate the actual and estimated payouts to our CEO based on our performance, relative to target payouts under our ESTIP and LTIP programs over the last three fiscal years based on the closing price of the Company’s common stock on December 30, 2022 ($6.70).

Equitrans Midstream Corporation – 2023 Proxy Statement   35

Notes:

(1)

Target Value reflects: (i) base salary, (ii) target ESTIP award, and (iii) grant date value of awards under the 2018 LTIP.

(2)

Realizable Value at December 31, 2022 reflects: (i) the actual paid base salary during each calendar year; (ii) the actual ESTIP award earned for each calendar year, and (iii) the estimated LTIP value at December 31, 2022, assuming performance at the end of the applicable performance period remains unchanged from performance as of December 31, 2022. For the (i) 2022 Performance Share Unit Program (PSUP): amount reflects December 31, 2022 TSR rank versus the TSR Peer Group and associated performance modifier (at 0%); (ii) 2021 PSUP: amount reflects December 31, 2022 TSR rank versus the 2021 TSR peer group and associated performance modifier (at 0%); and (iii) 2020 PSUP: amount reflects the actual amount earned that will be paid in the first quarter of 2023 for the respective performance periods at 19.1%, multiplied by the closing price of the Company’s common stock on December 30, 2022 ($6.70), including accrued dividends. For restricted shares, reflects the closing price of the Company’s common stock on December 30, 2022 ($6.70), including accrued dividends. The amounts shown reflect the core components of the Company’s compensation program and do not include the special, one-time, performance-based 2021 MVP Performance Share Unit Program (MVP PSUP), the vesting of which is contingent upon timely completion of the Mountain Valley Pipeline (the MVP Project).

As noted above, one of the several factors the Committee considers in determining TDC is the relationship of such TDC with a group of peer companies selected by the Committee in consultation with Mercer, its independent compensation consultant for 2021 and a portion of 2022. For 2022, the Compensation Peer Group was unchanged from the 2021 compensation peer group and was composed of the following ten companies that are generally similar to the Company with respect to business activity and at the time of selection were of a similar size as measured by market capitalization, enterprise value, total assets and earnings before interest, taxes, depreciation and amortization (EBITDA):

➢ Crestwood Equity Partners LP	➢ National Fuel Gas Company
➢ DCP Midstream, LP	➢ ONEOK Inc.
➢ Enable Midstream Partners, LP	➢ Plains All American Pipeline, L.P.
➢ EnLink Midstream, LLC	➢ Targa Resources Corp.
➢ Magellan Midstream Partners, L.P.	➢ Western Midstream Partners, LP

Determination of Final Total Compensation for Performance-Based Elements

Throughout the year, the Committee reviews performance against the established ESTIP and LTIP program performance metrics. Once the fiscal year has ended, the Committee determines achievement of the

36   Equitrans Midstream Corporation – 2023 Proxy Statement

performance goals for the ESTIP and, after the completion of the performance period, the applicable LTIP awards, determines the actual amount to be paid under the ESTIP and each PRSU award, as applicable, and recommends such amounts to be paid under the ESTIP and each PRSU award, as applicable, to the Board.

Role of Independent Compensation Consultant

The Committee has the sole authority to hire, terminate and approve fees for compensation consultants, outside legal counsel and other advisors as it deems to be necessary to assist in the fulfillment of its responsibilities. With respect to compensation decisions applicable to the NEOs that were made by the Committee prior to August 25, 2022, the Committee utilized Mercer as its independent compensation consultant. On August 25, 2022, following a request for proposal process in the ordinary course of business, the Committee approved the engagement of Pay Governance and Pay Governance served as the Committee’s independent compensation consultant for the remainder of 2022.

During the period of its engagement during 2021 and a portion of 2022, Mercer provided the Committee with market data and counsel regarding executive officer compensation programs and practices and, beginning August 25, 2022, Pay Governance provided the Committee with such market data and counsel, and in the case of both Mercer and Pay Governance, including specifically:

➢

competitive benchmarking;

➢

peer group identification and assessment;

➢

advice and market insight as to the form of and performance measures for annual and long-term incentives;

➢

marketplace compensation trends in the Company’s industry and generally; and

➢

a risk assessment of the Company’s compensation programs.

Neither representatives of Mercer or Pay Governance make recommendations on, or approve, the amount of compensation for any executive officer. The Committee has affirmatively determined that no conflict of interest arose or has arisen (as applicable) in connection with the work of Mercer or Pay Governance as compensation consultant for the Committee.

Shareholder Engagement and Say-on-Pay Results

Shareholders holding more than 97% of our outstanding shares voted at our 2022 annual shareholders’ meeting to approve our say-on-pay proposal regarding our NEOs’ 2021 compensation. Based on these results, the Committee concluded that the compensation programs and practices specifically designed to our Company’s needs have strong shareholder support. Nonetheless, the Committee did undertake a thorough analysis of its compensation programs and made appropriate modifications as described below.

2022 Compensation Program Elements

The following discussion outlines the targeted 2022 executive compensation program and what we actually paid our NEOs in 2022.

2022 Base Salaries

After reviewing the market data based upon the Compensation Peer Group, in December 2021, the Committee recommended and our Board approved increases to Ms. Charletta’s and Messrs. Karam’s, Moore’s and Pietrandrea’s respective base salaries during 2022, as described below, to ensure that our compensation program remained market-competitive and, in the case of Mr. Moore, to reflect the Committee’s and Board’s view of Mr. Moore’s broad contributions to and portfolio of responsibilities within the Company.

2022 Annual Incentives (ESTIP)

Our ESTIP focuses our NEOs’ attention to achieving key near-term goals that drive long-term performance for our Company. In 2022, our ESTIP’s performance goals and results were as shown:

ESTIP Metrics

Our 2022 ESTIP generally followed from prior years’ annual short-term incentive programs by continuing to reflect both financial metrics that are closely aligned with key drivers of our business and HSSE metrics that underpin the business and are part of working to position the Company for a lower-carbon economy.

The Committee determined to maintain that 60% of our ESTIP should be payable based on the Company’s Economic Adjusted EBITDA, which is the sum of our Adjusted EBITDA (defined below) and any Deferred Revenue (defined below). The Committee continues to believe that Economic Adjusted EBITDA best reflects the Company’s economic performance as it removes non-recurring, non-operational gains, losses and impairments and eliminates the potential for Deferred Revenue amounts to lead to either outsized or diminished incentive payments. Additionally, the Committee continued to recognize the importance investors place on the Company’s ability to generate free cash flow and, accordingly, the Committee determined to retain Free Cash Flow as a metric to incentivize executives’ performance. The Company derives the targets for its financial metrics for a given year from the Company’s business plan for that year, which undergoes a rigorous review process and is ultimately approved by the Board. The Company understands that the 2022 target for Free Cash Flow was less than the achieved Free Cash Flow result for 2021; however, the 2022 Free Cash Flow target was derived based on the approved business plan for 2022, which reflected, among other things, estimates and assumptions at the time of plan approval regarding business opportunities and capital expenditures, including for organic growth projects, information received from the Company’s producer customers, and other factors.

Recognizing the Company’s continued efforts to institutionalize its commitment to and pursuit of ESG and sustainability initiatives, including the reduction of Greenhouse Gas and methane emissions and the enhancement of the Company’s ESG platform in an effort to position itself for a lower-carbon economy, and shareholders’ and other stakeholders’ continued focus on ESG and sustainability matters, particularly in respect of climate change, the Committee determined to increase the focus on sustainability metrics in the 2022 ESTIP, which it believed would help to further incentivize sustainable business practices and emphasize, including for employees and other stakeholders, the importance placed by the Company on such practices. First, the Committee determined to again include a methane emissions mitigation metric, which provided that the Company undertake and complete certain projects to achieve targeted methane emissions mitigation. Second, the Committee, taking into account management’s recommendation, added a new sustainability metric reflecting the timely completion and submission of a comprehensive report in response to the voluntary Water CDP Security questionnaire, which involved compiling the first Company-wide water inventory.

Finally, to continue to evolve, and further enhance, the Company’s safety performance culture, the Committee determined to utilize a refashioned safety metric, the Safety Proactivity Rate, in place of Incidents with Serious

38   Equitrans Midstream Corporation – 2023 Proxy Statement

Potential (ISP) and Adjusted Incidents with Serious Potential (Adjusted ISP) Rates. The Safety Proactivity Rate is based in part on the ISP rate and takes into account observations with serious potential (similar to the Adjusted ISP rate for the 2021 ESTIP), however, it has a target that resets each quarter, which the Committee believes rewards sustained performance and promotes employees’ continued focus on safe operations throughout the entire year to an even greater extent than was the case with the ISP and Adjusted ISP metrics.

Metric	What it Measures	What it Does
Economic Adjusted EBITDA	• Key business indicator used by management to evaluate overall performance.	✓ Rewards our NEOs based on our annual financial results.
Free Cash Flow	• Demonstrates cash flow available to shareholders after all obligations have been met and provides a view of the overall health of the business.	✓ Focuses our NEOs on optimizing capital spending and liquidity.
Health, Safety, Sustainability and Environmental	• Determines performance against stringent safety, sustainability and environmental goals.	✓ Promotes a culture where safety, health, sustainability and the environment is embedded into all aspects of our decision- making.

2022 ESTIP Performance — Rager Mountain Natural Gas Storage Field Incident. In February 2023, consistent with its typical timing, the Committee certified the performance for the 2022 plan year under the ESTIP resulting in a payout of 161% as reflected in the table below. In connection with such certification, management, the Committee and the Board recognized that the investigation of the November 2022 incident involving the venting of natural gas from a storage well at Equitrans, L.P.’s (a subsidiary of the Company) Rager Mountain natural gas storage field (the Rager Mountain incident) would not be completed until several months after the performance for the 2022 plan year was certified. Given the fact that the investigation of the Rager Mountain incident is ongoing (including an analysis of the root cause and whether and to what extent, if any, the Company, its personnel or its practices may have contributed to the incident), management recommended, and the Committee and the Board determined, that the approximately $8.1 million of costs incurred and reserved for by the Company in 2022 in respect of such incident would not be reflected in Economic Adjusted EBITDA for purposes of the ESTIP (notwithstanding that it is otherwise added back to Adjusted EBITDA). This resulted in an approximate 5 percentage point decrease in the ESTIP payout for the 2022 plan year. See Appendix B for a reconciliation of Adjusted EBITDA, a non-GAAP supplemental financial measure and Economic Adjusted EBITDA for ESTIP purposes to net income, the most directly comparable GAAP financial measure. In connection with ongoing oversight by the Board of the post-incident response workstreams, including the root cause analysis, the Committee and the Board will consider whether and to what extent, if any, such incident may affect the NEOs’ 2023 compensation as additional information regarding the incident and the root cause thereof becomes available. See the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 for more information regarding the Rager Mountain incident.

Adjusted EBITDA means, as applicable, net income (loss), plus income tax expense (benefit), net interest expense, loss on extinguishment of debt, depreciation, amortization of intangible assets, impairments of long-lived assets and equity method investment, payments on the preferred interest in EQT Energy Supply, LLC (Preferred Interest), non-cash long-term compensation expense, Rager Mountain incident and less equity income, AFUDC-equity, unrealized gain (loss) on derivative instruments, gain on sale of gathering assets and adjusted EBITDA attributable to noncontrolling interest. See “Rager Mountain Natural Gas Storage Field Incident” above for a discussion of certain discretion exercised for purposes of determining the Economic Adjusted EBITDA component of the 2022 ESTIP payout.

•

Deferred Revenue is the difference between the cash received from the contractual minimum volume commitment under the February 2020 Gas Gathering and Compression Agreement with EQT Corporation (EQT Global GGA) and the revenue recognized over the 15-year contract term.

(2)

Free Cash Flow is calculated as net cash provided by operating activities plus principal payments received on the Preferred Interest and payment made in respect of the EQT Cash Option (defined in Appendix B) and less net cash provided by operating activities attributable to noncontrolling interest, dividends paid to the holders of the Company’s Series A Perpetual Convertible Preferred Shares, premiums and fees paid on extinguishment of debt, capital expenditures (excluding the noncontrolling interest share (40%) of Eureka Midstream capital expenditures) and capital contributions to Mountain Valley Pipeline, LLC. As provided under the ESTIP, the 2022 Free Cash Flow excludes specified circumstances or events that occurred during the 2022 plan year. See Appendix B for a reconciliation of Free Cash Flow to net cash provided by operating activities, the most directly comparable GAAP financial measure.

HSSE metrics defined as:

•

Safety Proactivity Rate: measures the level of safety proactivity throughout the Company and is calculated by adding the number of Observations with Serious Potential (OSPs) and the Corrected Safety Opportunities (CSOs) and subtracting the ISPs (each as defined below).

◦

OSP: an observation of an activity with precursors that has the potential to become an ISP before the event occurs.

◦

CSO: reported hazards (without serious potential), deficient procedures or processes, or suggested improvements that have been corrected or implemented.

◦

ISP: An event with a precursor that can lead to serious injuries and fatalities (the measurement of which can promote awareness and allow the prevention of injuries).

•

Methane Emission Mitigation: achieve an annualized reduction of methane emissions, relative to 2019 baseline total methane emissions, including Eureka Midstream and excluding MVP, by the completion of certain projects.

•

Water CDP Disclosure Submission: timely completion and submission of a comprehensive report in response to the voluntary CDP Water Security questionnaire, which involved compiling the first Company-wide water inventory.

2022 NEO ESTIP Opportunities and Payments

In December 2021, the Board, upon recommendation of the Committee, increased the target percentage for Mr. Oliver’s short-term incentive plan opportunity for the 2022 plan year as a result of market comparisons and individual performance and to further the Company’s emphasis on variable, at-risk compensation. The NEOs’ short-term incentive opportunities for 2022 were as follows:

NEO	2021 Target		2022 Target		2022 Threshold			2022 Target			2022 Maximum			2022 ESTIP Award Earned
Thomas F. Karam	​	120%	​	120%	​	$	474,000	​	$	948,000	​	$	1,896,000	​	$	1,526,280

Long-Term Incentive Program (LTIP)

Our LTIP aligns our NEOs’ interests with those of our shareholders by providing the opportunity to earn incentive compensation based on the Company’s long-term success.

Both RSAs and PRSUs awarded to our NEOs are paid in Company stock, further aligning their interests with those of our shareholders. For 2022, the Committee, in consultation with Mercer, retained the allocation of RSAs and PRSUs that was utilized in 2021.

Time-Based RSAs

The time-based RSAs issued under the 2022 LTIP program cliff vest after three years of continuous service following the vesting commencement date, which was January 1, 2022. The grant of time-based RSAs helps align our NEOs’ interests with those of our shareholders and provides a powerful retention incentive that assists us in maintaining continuity among our senior executive team.

Performance-Based RSUs (PRSUs)

For purposes of the 2022 LTIP, the Committee, with input from other members of the Board and Mercer, elected to retain the Relative TSR metric used in the 2021 program and the Committee recommended, and the Board approved, the 2022 long-term performance-based incentive design.

By basing our PRSUs on Relative TSR performance over the 2022-2024 performance period, we align our NEOs’ interests with those of our shareholders by tying compensation outcomes to our performance relative to our TSR Peer Group (discussed below) and to delivering shareholder value.

The table below summarizes the Relative TSR performance goals and potential payouts:

2022-2024 PRSUs — Relative TSR*
Threshold	Target	Maximum
25th Percentile	50th Percentile	75th Percentile or Above
50% Payout	100% Payout	200% Payout

*

TSR performance between points will be determined by straight-line interpolation.

Our 2022 TSR Peer Group consists of a subset of similarly-sized C-corporations (or limited partnerships that have elected to be treated as C-corporations for tax purposes) with market values in excess of  $4 billion included in the Alerian US Midstream Energy Index (AMUS), as well as all members of the Compensation Peer Group, with the exception of Enable Midstream Partners, LP as a result of its acquisition in December 2021 by Energy Transfer LP. The Committee selected the TSR Peer Group in consultation with Mercer, its independent compensation consultant for 2021 and a portion of 2022. The 2022 TSR Peer Group represents a decrease in the number of peer companies from our 2021 TSR peer group given the acquisition of Enable Midstream Partners, LP. The Committee believes this peer group, which is larger than the Compensation Peer Group, is appropriate as it is designed to serve as a suitable group of peers from which to measure TSR performance.

Equitrans Midstream Corporation – 2023 Proxy Statement   41

To determine Relative TSR we utilize the 15-day average closing price of our stock prior to the beginning of the performance period and the 15-day average closing price of our stock at the end of the performance period.

The target long-term incentive awards to the NEOs were made consistent with the Committee’s methodology described above and in December 2021, the target percentage opportunities were increased for Ms. Charletta and Messrs. Oliver and Moore from the target long-term incentive awards approved for such NEOs in 2021 as a result of market comparisons with our Compensation Peer Group and individual performance and to further the Company’s emphasis on variable at-risk compensation. The targets and number of RSAs and PRSUs awarded to the NEOs were as follows:

NEO	2021 Target		2022 Target		2022 Time-Based RSAs Awarded		2022 PRSUs Awarded
Thomas F. Karam	​	575%	​	575%	​	131,800	​	307,520
Kirk R. Oliver	​	220%	​	260%	​	37,720	​	88,010

Brian P. Pietrandrea	​	100%	​	100%	​	7,980	​	18,620

2020 PSUP Long-Term Incentive Awards

In February 2023, the Committee certified the performance under the 2020 PSUP, which resulted in a 19.1% payout based upon the Company’s Relative TSR over the respective performance periods as set forth below:

2020 PSUP MATRIX — RELATIVE TOTAL SHAREHOLDER RETURN EACH CALENDAR YEAR PERIOD AND CUMULATIVE THREE-YEAR PERIOD​
​	Threshold	Target	Maximum

Other Considerations Important to Our Compensation Program

In general, our NEOs participate in the same retirement and health and welfare benefit plans offered to other Company employees. The same contribution amounts, deductibles and plan design provisions are generally applicable to all employees.

Stock Ownership Guidelines

The NEOs are subject to stock ownership guidelines requiring each NEO to hold a specified multiple of the NEO’s base salary (five times for the CEO and three times for all other NEOs). The NEOs are required to meet the ownership guidelines within a reasonable period of time from becoming an NEO; provided, however, in the event the individual ownership guidelines are not met within a five-year period, the net shares acquired through incentive compensation plans must be retained. As of December 31, 2022, Mr. Karam and Ms. Charletta met their respective ownership guidelines, as their Company stock holdings represented approximately 9.2 and 3.2 times their base salaries, respectively. Our remaining NEOs are on track to satisfy the guidelines within the prescribed time period or through retention of net shares as described above.

42   Equitrans Midstream Corporation – 2023 Proxy Statement

Retirement Program

Our NEOs participate in the same defined contribution 401(k) plan as all other Company employees. During 2022, we contributed an amount equal to 6% of each participant’s base salary and annual incentive award to an individual account for each employee (subject to Internal Revenue Service (IRS) regulations).

We also match every participant’s elective deferral contributions by an amount equal to 50% of each dollar contributed, subject to a maximum Company matching contribution of 3% of the employee’s base salary and annual incentive awards (subject to IRS regulations).

We do not provide separate executive retirement benefits for our NEOs.

Health Benefits

Our NEOs participate in the same health and welfare benefit plans as all other Company employees. We provide medical, prescription drug, dental, vision, short- and long-term disability, wellness and employee assistance programs. We also provide our NEOs and certain other senior members of management with access to an annual executive physical and modest additional life / accidental death & dismemberment insurance coverage reflecting their compensation levels. NEOs pay the same health benefit contribution amounts and have the same deductibles as are applicable to all other Company employees.

Limited Perquisites

The perquisites program provides an executive physical and access to a concierge medical program as well as an annual stipend to offset the cost of financial planning services. During 2022, Mr. Karam also was reimbursed for the costs of his 2022 monthly dues for his club membership and minimal usage of a leased aircraft for business-related purposes. The Company reflected the entire cost of the monthly dues for the membership and the usage of the leased aircraft in the Summary Compensation Table below. However, Mr. Karam’s use of the club is primarily for business purposes, and the Company therefore believes that only a portion of the cost represents a perquisite. Additionally, Mr. Karam’s usage of the leased aircraft was for business-related purposes, however, the Company believes under SEC rules such usage would be considered a perquisite. See footnote (3) to the Summary Compensation Table below for a discussion of the perquisites provided to the NEOs during 2022. No tax gross-ups were provided on perquisites for our NEOs.

Compensation Policies and Practices and Risk Management

In early 2023, members of the Company’s management, with the assistance of Pay Governance, the Committee’s independent compensation consultant, reviewed the risk assessment of the Company’s compensation programs for all employees. The results of such assessment were presented to the Committee. Based on the assessment, the Company and the Committee believe that the Company’s compensation programs are appropriate and do not create risks reasonably likely to have a material adverse impact on the Company.

Agreements with the Named Executive Officers

The Committee believes that severance protections play a valuable role in attracting, motivating and retaining highly talented executives. Accordingly, we provide such protections for the NEOs under their agreements that are described in detail under the caption “Potential Payments Upon Termination or Change of Control” below. Importantly, the executive agreements include covenants not to solicit employees, customers, potential customers, vendors or independent contractors from, or, with respect to all NEOs except Mr. Pietrandrea under his agreement in effect during 2022, compete with, the Company for a specified period of time and to maintain the confidentiality of the Company’s information. The Committee believes that these covenants are extremely valuable to the Company.

2023 Compensation Program

In February 2023, the Committee recommended, and the Board approved, the 2023 compensation program, which included certain changes from the 2022 compensation program that the Committee believes better align the compensation program with evolving market practice, while continuing to promote the pursuit of

Equitrans Midstream Corporation – 2023 Proxy Statement   43

near- and long-term objectives for the Company and its shareholders. With respect to the LTIP, the Committee determined to modify the existing mix of time- and performance-based incentive awards to 45% time-based and 55% performance-based from 30% time-based and 70% performance-based in the 2022 LTIP design and added two additional metrics (including metrics based upon Free Cash Flow and sustainability), in addition to relative TSR, to the 2023 performance share unit program to emphasize and drive performance in areas that are important to the Company and its shareholders, particularly incorporating long-term objectives promoting the continued maturation of the Company’s sustainability program. The Committee also reviewed, following the engagement of Pay Governance and its review of the Company’s compensation programs and market practice, award vesting conditions and provided, in light of such practice, generally for vesting of both LTIP and ESTIP awards at the greater of target or actual levels of performance, in the event of the consummation of a change in control transaction and provided for pro-rata vesting of an award in the event an executive is terminated by the Company without cause, subject to achievement of the specified performance conditions. Lastly, the Committee recommended, and the Board approved, amendments to the NEOs’ existing agreements to increase Mr. Karam’s base salary multiplier, align the benefits continuation payment for each NEO with his or her base salary multiplier and transition Mr. Pietrandrea from a change of control agreement to a non-competition agreement.

Report of the Human Capital and Compensation Committee

We have reviewed and discussed the CD&A with the Company’s management. Based on our review and discussions, we recommend to the Board of Directors that the CD&A be included in the Equitrans Midstream Corporation Proxy Statement for 2023.

This report has been furnished by the Human Capital and Compensation Committee
