Explanatory Note

EQT Corporation (the Company) originally filed its Quarterly Report on Form 10-Q for the period ended September 30, 2014 (the Original Filing) with the Securities and Exchange Commission (SEC) on October 23, 2014. The Company is filing this Amendment No. 1 to its Quarterly Report on Form 10-Q (the Form 10-Q/A and, together with the Original Filing, the Form 10-Q) solely to re-file Exhibit 10.01 to the Original Filing in response to certain inquiries received from the SEC in connection with the Company’s confidential treatment request for certain portions of the First Amended and Restated Limited Liability Company Agreement of Mountain Valley Pipeline, LLC, dated as of August 28, 2014.

Except for the foregoing, this Form 10-Q/A does not amend the Original Filing in any way and does not modify or update any disclosures contained in the Original Filing, which continues to speak as of the date of the Original Filing (including, but not limited to, any forward-looking statements made in the Original Filing, which have not been revised to reflect events that occurred or facts that became known after the Original Filing, and such forward-looking statements should be read in their historical context). Accordingly, this Form 10-Q/A should be read in conjunction with the Original Filing and the Company’s other filings made with the SEC subsequent to the Original Filing.
