Equitrans Midstream Statement Regarding Mountain Valley Pipeline Project

February 3, 2022

Equitrans Midstream (NYSE: ETRN), today, issued the following statement regarding the Mountain Valley Pipeline (MVP) project:

On Wednesday, February 2, 2022, the U.S. Fourth Circuit Court of Appeals issued a decision vacating MVP’s Biological Opinion and remanding it on specific issues. The Court’s written decision was initially issued under seal, due to the potential identification of and reference to endangered species locations, and it is expected the seal will be lifted shortly.

The MVP project team is taking time to thoroughly review the information outlined in the decision and is evaluating the project’s next steps regarding the Biological Opinion. We remain committed to completing the MVP project and believe the concerns associated with MVP’s Biological Opinion can be addressed by the agency.
