On September 7, 2023, the Board of Directors (Board) of Equitrans Midstream Corporation announced that, effective January 1, 2024, Mr. Thomas F. Karam will step down as Chief Executive Officer (CEO) of the Company and Diana M. Charletta, currently the Company?s President and Chief Operating Officer, will succeed Mr. Karam as CEO. Mr. Karam has served as the CEO of the Company since September 2018. The leadership transition reflects the Company?s progress on the Mountain Valley Pipeline (MVP) project, which is targeted for completion by year-end 2023, and Mr. Karam?s and the Board?s belief that this represents an appropriate point to execute on the Company?s leadership succession plan.

The Board and Mr. Karam desire that Mr. Karam remain, and Mr. Karam has agreed to remain, with the Company as Executive Chairman to provide advice, guidance and assistance, including working in conjunction with the CEO to define the Company?s strategy and in connection with the Company?s shareholder and other stakeholder engagement efforts. Ms. Charletta, age 51, was appointed President and Chief Operating Officer of the Company in July 2019, having previously served as executive vice president and chief operating officer of the Company since September 2018, and has served as a director of the Company since April 2022. She also served as president, chief operating officer, and a director of the general partner of EQM Midstream Partners, LP (EQM) from July 2019 until the Company?s acquisition of the outstanding public common units of EQM in June 2020 (and was executive vice president, chief operating officer and a director from October 2018 to July 2019), as well as executive vice president, chief operating officer and a director of the general partner of EQGP Holdings, LP (EQGP) from October 2018 until the closing of the Company?s acquisition of the outstanding public common units of EQGP in January 2019.

Ms. Charletta joined EQT Corporation (EQT), the former parent company of the Company, in 2002 as a senior pipeline engineer and from that time held various management positions with increased responsibility. She assumed the role of Senior Vice President of Midstream Operations of a subsidiary of EQT in December 2013 and was promoted to Senior Vice President of Midstream Engineering and Construction in July 2017, serving in that role until the Company?s separation from EQT in November 2018.
