There’s trouble brewing in EQT-land. Once upon a time, EQT was both a producer (drilling) and midstream (pipeline) company. But then so-called activist investors forced the company (after its merger with Rice Energy) to split in two–drilling and pipelines. The split happened in November 2018 (see It’s Here! EQT Midstream Division Now Split into Standalone Co.). The new pipeline company was eventually renamed Equitrans Midstream. The two companies, EQT and Equitrans, have maintained a close relationship with Equitrans doing the lion’s share of gathering EQT’s production and getting it to market. But now the two sides are squabbling over an Equitrans project called Hammerhead, and that disagreement has gone public with Equitrans issuing a pointed warning via press release.
