As part of their parent company EQT Corp.'s spinoff of its natural gas midstream business, EQT Midstream Partners LP, EQT Midstream Services LLC and EQT GP Holdings LP changed their names to EQM Midstream Partners LP, EQM Midstream Services LLC and EQGP Holdings LP, respectively.

EQT's separation of its upstream and midstream businesses involves the drop down of its midstream assets to EQM Midstream and a merger between EQM Midstream and Rice Midstream Partners LP. EQT is also selling Rice Midstream's incentive distribution rights to EQGP Holdings. The resulting new midstream company would be named Equitrans Midstream Corp.

The companies filed for the name changes with Delaware on Oct. 12, according to Oct. 15 SEC forms. The separation is scheduled to close in the fourth quarter, pending regulatory approval.

EQT is the largest producer of natural gas in the U.S. Its midstream companies own and operate assets in the Appalachian Basin.
