EQT now has two activist investors rattling its cages in advance of the energy company’s planned $6.7 billion acquisition of Rice Energy.

D.E. Shaw, a $42 billion investment management firm, took a tough stance on EQT Thursday, citing the Pittsburgh company’s “inadequate” responses to shareholder concerns about the pending Rice purchase and its plans after to break up the company after the deal is completed.

Just two months ago activist hedge fund Jana Partners announced a 5.8 percent stake in EQT in an effort to block the deal.

Reps from EQT declined to comment. Jana reps did not respond to requests to comment.
