During this meeting, Mr. Porges advised that EQT management was prepared to recommend to the EQT board an all-stock business combination transaction at an exchange ratio of 0.33 of a share of EQT common stock for each share of Rice common stock, which implied a value of $26.18 per share of Rice common stock at EQT’s most recent closing stock price. Mr. Porges indicated that EQT was open to Rice having representation on the EQT board after closing, although the number and identities of such directors were not discussed. Mr. Porges advised that EQT’s next board meeting was July 13, 2016 and requested a response prior to that meeting. Mr. Porges further advised that EQT wanted to move quickly towards executing a definitive merger agreement.

In response to questions from the Rice board, representatives of Barclays and ~~Exhibits~~management noted that Company A was much smaller than EQT, unlike EQT was not investment grade and, at the high end of the proposed premium range, Rice stockholders would own more of the combined company than Company A’s stockholders. Mr. Rice noted that a variety of governance-related matters would have to be worked out between the parties, including the management positions and the composition of the combined company board. Representatives of Barclays also noted that additional diligence of Company A would be necessary to assess value. After discussion, the Rice board authorized management to request due diligence materials from Company A and to continue to evaluate Company A’s proposal. Mr. Rice next updated the Rice board on the status of discussions with EQT, including the reaffirmation of its proposal of 0.33 of a share of EQT common stock for each share of Rice common stock. After discussion, the Rice board authorized management to make a new proposal to EQT of 0.35 of a share of EQT common stock for each share of Rice common stock, which implied a value of $26.45 per share of Rice common stock at EQT’s then-trading stock price.

for the period of April 1, 2017 to December 31, 2017

The disclosure on page 106 of the Proxy Statement is hereby supplemented by revising the first complete paragraph by adding a new penultimate sentence:

Although Citi’s and its affiliates’ security holdings in Rice may change from time to time, as the EQT board was aware, as of May 16, 2017, Citi and/or certain of its affiliates held for their own account approximately 74,383 shares of Rice common stock representing, based on publicly available information, less than 0.05% of the then-outstanding shares of Rice common stock.

The disclosure on page 140 of the Proxy Statement is hereby supplemented by revising the fourth complete paragraph on the page in its entirety as follows:

Concurrently with the execution of the merger agreement, EQT entered into a voting agreement, attached as Annex F to this joint proxy statement/prospectus, with the named Rice stockholders pursuant to which each of the named Rice stockholders has agreed, among other matters and upon the terms and subject to the conditions set forth in the voting agreement, to vote all of their shares of Rice common stock in favor of the merger agreement proposal and the other actions contemplated by the merger agreement and against any proposal that would reasonably be expected to result in any condition to the consummation of the merger set forth in the merger agreement not being fulfilled. As of the record date for the Rice special meeting, the named Rice stockholders held approximately 36,832,830 shares of Rice common stock in the aggregate, or approximately 15.1% of the voting power of Rice as of the record date. Given the exchange ratio of 0.37, these 36,832,830 shares of Rice common stock would become, upon completion of the merger, approximately 13.6 million shares of EQT common stock, which would be approximately 5% of the EQT common stock issued and outstanding following the merger and assuming full conversion to EQT common stock of all Rice common stock eligible to receive the merger consideration.

— END OF SECOND SUPPLEMENT TO JOINT PROXY STATEMENT/PROSPECTUS —

Update Regarding Certain EQT Shareholder Litigation

As previously disclosed, EQT received a letter dated August 17, 2017 on behalf of purported EQT shareholder Robert Garfield demanding that EQT file suit against the members of the board of directors of EQT (the “EQT board”). The letter alleged, among other things, that the board members breached their fiduciary duties during the process leading to EQT’s entry into the Merger Agreement, and provided or supervised the allegedly misleading and incomplete disclosures in the joint proxy statement/prospectus filed by EQT and Rice in connection with the Merger. On October 13, 2017, the EQT board sent a response identifying various deficiencies in the letter. On October 18, 2017, a putative derivative and purported class action lawsuit captioned Garfield v. Porges, et al., Case GD-17-14222 was filed in the Court of Common Pleas of Allegheny County, Pennsylvania against members of the EQT board, with EQT as a nominal defendant. On October 25, 2017, Garfield filed motions requesting, among other things, a preliminary injunction that would prevent the defendants from closing the shareholder vote on whether to issue shares of EQT. On October 27, 2017, defendants filed preliminary objections raising deficiencies in the complaint. The court has set a hearing on the preliminary injunction motion and the preliminary objections on November 6, 2017. A copy of the complaint is attached as Exhibit 99.5 hereto and incorporated by reference herein. EQT and EQT’s defendant directors believe that the claims of the Garfield Plaintiff are without merit.
