Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Introduction

The following unaudited pro forma condensed combined financial statements (the “pro forma financial statements”) have been prepared to reflect the effects of the merger (as defined in the Explanatory Note to this Current Report on Form 8-K) on the financial statements of EQT Corporation (“EQT”). The unaudited pro forma condensed combined balance sheet (the “pro forma balance sheet”) is presented as if the merger had occurred on September 30, 2017. The unaudited pro forma combined statements of operations (the “pro forma statements of operations”) for the year ended December 31, 2016, and the nine months ended September 30, 2017, are presented as if the merger had occurred on January 1, 2016. The historical combined financial information has been adjusted to reflect factually supportable items that are directly attributable to the merger and, with respect to the statements of operations only, are expected to have a continuing impact on the combined results.

The following unaudited pro forma financial statements, derived from the historical consolidated financial statements of EQT and Rice, have been adjusted to reflect the following:

·                  EQT’s merger with Rice Energy Inc. (“Rice”) under the acquisition method of accounting;

·                  assumed conversion of common units in Rice Energy Operating LLC into the right to receive the consideration received by holders of Rice’s common stock in the merger;

·                  assumed redemption of the Series B preferred interest in Rice Midstream Holdings LLC  by EQT for $430 million, redemption of common units in Rice Midstream GP Holdings LP held by EIG Funds for $125 million and the related elimination of preferred dividends and impacts on noncontrolling interests;

·                  adjustments to Rice’s historical consolidated financial statements to reflect the acquisition of Vantage Energy LLC and Vantage Energy II, LLC (collectively, “Vantage”) as though that acquisition occurred on January 1, 2016;

·                  elimination of historical transactions between Rice and EQT that would be treated as intercompany transactions after the merger;

·                  issuance of $3.0 billion in new EQT notes (which EQT closed on October 4, 2017), with maturities of three, five and ten years (the “EQT notes”), to fund a portion of the cash consideration paid in the merger and the planned extinguishment of Rice’s senior notes (the “Rice notes”), Rice’s revolving credit facility (the “Rice credit facility”) and Rice Midstream Holdings LLC’s revolving credit facility (the “Rice Midstream Holdings credit facility,” and together with the Rice credit facility, the “Rice credit facilities”) as the interest rate and terms on the Rice notes and Rice credit facilities are significantly less favorable than what EQT obtained with this issuance;

·                  planned upsize of EQT’s revolving credit facility (which EQT completed on July 31, 2017);

·                  assumption of liabilities for transaction-related expenses;

·                  adjustment of depreciation, depletion and amortization related to the step up of property, plant and equipment to estimated fair value and to adjust the depreciation expense on certain Rice midstream assets to EQT’s depreciation policies;

·                  amortization of the intangible assets identified as part of the assets acquired; and

·                  estimated tax impact of pro forma adjustments.

The pro forma financial statements have been prepared using the acquisition method of accounting using the accounting guidance in Accounting Standards Codification 805, Business Combinations (“ASC 805”), with EQT treated as the acquirer. The acquisition method of accounting is dependent

1

upon certain valuations and other studies that have yet to progress to a stage where there is sufficient information for a definitive measure. Accordingly, the pro forma adjustments are preliminary, have been made solely for the purpose of providing pro forma financial statements, and are subject to revision based on a final determination of fair value as of the date of acquisition. Differences between these preliminary estimates and the final acquisition accounting may have a material impact on the accompanying pro forma financial statements and the combined company’s future results of operations and financial position.

The pro forma financial statements are provided for informational purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated financial position of EQT would have been had the merger occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position. The pro forma financial statements should be read in conjunction with:

·                  The accompanying notes to the pro forma financial statements;

·                  The audited consolidated financial statements and accompanying notes of EQT contained in its Annual Report on Form 10-K for the year ended December 31, 2016;

·                  The audited consolidated financial statements and accompanying notes of Rice contained in Part II, Item 8 of its Annual Report on Form 10-K for the year ended December 31, 2016, which were filed by EQT in Exhibit 99.1 to EQT’s Current Report on Form 8-K filed September 27, 2017;

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1.                                      Basis of Presentation

The pro forma financial statements have been prepared to reflect the effects of the merger on the financial statements of EQT. The pro forma balance sheet is presented as if the merger had occurred on September 30, 2017. The pro forma statements of operations for the year ended December 31, 2016, and the nine months ended September 30, 2017, are presented as if the merger had occurred on January 1, 2016. The historical consolidated financial information has been adjusted to reflect factually supportable items that are directly attributable to the merger and, with respect to the statements of operations only, are expected to have a continuing impact on the combined results.

The pro forma financial statements have been prepared using the acquisition method of accounting using the accounting guidance in ASC 805, with EQT treated as the acquirer. The acquisition method of accounting is dependent upon certain valuations and other studies that have yet to progress to a stage where there is sufficient information for a definitive measure. Accordingly, the pro forma adjustments are preliminary, have been made solely for the purpose of providing pro forma financial statements, and are subject to revision based on a final determination of fair value as of the date of acquisition. Differences between these preliminary estimates and the final acquisition accounting may have a material impact on the accompanying pro forma financial statements and the combined company’s future results of operations and financial position.

The pro forma financial statements are provided for informational purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated financial position of EQT would have been had the merger occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position.

2.                                      Pro Forma Adjustments and Assumptions

The adjustments are based on currently available information and certain assumptions that EQT believes are reasonable. The actual effects of these transactions will differ from the pro forma adjustments. A general description of these transactions and adjustments are provided as follows:

(a)           These adjustments reflect the estimated value of net consideration to be paid by EQT in the merger and the adjustment of the historical book values of Rice assets and liabilities as of September 30, 2017 to their estimated fair values. The following table represents the preliminary purchase price allocation to the assets acquired and liabilities assumed from Rice. This preliminary purchase price allocation has been used to prepare pro forma adjustments in the pro forma balance sheet and the pro forma statements of operations. The final purchase price allocation will be determined when EQT has completed the detailed valuations and necessary calculations subsequent to closing the merger. The final purchase price allocation will differ from these estimates and could differ materially from the preliminary allocation used in the pro forma adjustments. EQT expects to finalize its allocation of the merger consideration as soon as practicable after completion of the merger.

The preliminary purchase price allocation is subject to change as a result of several factors, including but not limited to:

·                  finalization of assumed and retired Rice indebtedness;

·                  changes in the estimated fair value of the Rice assets acquired and liabilities assumed as of the date of the merger, which could result from changes in future commodity prices, reserve estimates, inclusion of drilling synergies, other changes in cost assumptions, interest rates and

6

other facts and circumstances existing at the closing date of the merger compared to the filing date of the pro forma financial statements;

·                  the tax basis of Rice’s assets and liabilities as of the effective time of the merger;

·                  changes in the fair value of the noncontrolling interest attributable to the public unit holders of RMP, based on RMP’s share price at the effective time of the merger; and

·                  the risk factors described in “Risk Factors.”

As part of the preliminary price allocation, EQT identified intangible assets for customer contracts and the related customer relationships in Rice’s midstream business and for non-compete agreements for certain Rice executives. The fair value of the identified intangible assets was determined using the income approach which requires a forecast of the expected future cash flows generated. Goodwill is recognized to offset net deferred tax liabilities arising from differences between the purchase price allocated to Rice’s assets and liabilities based on fair value and the tax basis of these assets and liabilities. The merger and the post-closing merger (as defined in the Explanatory Note to this Current Report on Form 8-K), taken together, are intended to be treated for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code; therefore, Rice’s tax basis in its assets and liabilities will carry over to EQT and EQT must recognize a deferred tax liability for the net increase in the book value. The goodwill is also attributable to EQT’s qualitative assumptions of long-term value that the merger creates for EQT shareholders. Differences between the

7

preliminary purchase price allocation and the final purchase price allocation may change the amount of intangible assets and goodwill, if any, actually recognized at the effective time of the merger.

Pursuant to the merger agreement, EQT will pay $5.30 in cash and issue 0.37 of a share of EQT common stock for each share of Rice common stock outstanding at the effective time of the merger, which would result in the issuance by EQT of approximately 91,897,000 shares of EQT common stock valued at $5,989 million (based on the closing price as of November 10, 2017 of $65.18) and payment of $1,321 million in cash. This includes the conversion of common units in Rice Energy Operating LLC into the right to receive the merger consideration received by holders of Rice common stock in the merger. In addition, Rice will exercise its call right with respect to the Series B preferred equity interest in Rice Midstream Holdings, and EQT will pay approximately $430 million in cash at closing to redeem this interest. Also, EQT shall cause GP Holdings to acquire all of the issued and outstanding common units held by the EIG Funds for an aggregate cash purchase of $125 million. The final value of total merger consideration paid by EQT will be determined based on the actual number of shares treated as consideration at the effective time of the merger.

The pro forma fair value of natural gas and oil properties to be acquired includes the following (in thousands):

NYMEX strip pricing as of September 30, 2017 was utilized in determining the pro forma fair value of proved producing reserves at a discount rate of 8.0%, after adjustment for expenses and basis differential. An increase or decrease in commodity price as of the closing date will result in a corresponding increase or decrease in the fair value of proved producing properties.

(b)           The following pro forma adjustments eliminate historical transactions between Rice and EQT that would be treated as intercompany transactions after the merger:

1.                                      Elimination of $10.4 million of receivables and corresponding payables, consisting of $10.2 million for gathering transactions and $0.2 million for gas sales transactions in the pro forma balance sheet as of September 30, 2017.

2.                                      Elimination of $35.6 million in revenue and corresponding expenses related to the elimination of $30.0 million of gathering transactions and $5.6 million of transmission transactions in the pro forma statement of operations for the period ended September 30, 2017.

3.                                      Elimination of $41.5 million in revenue and corresponding expenses related to the elimination of $38.1 million of gathering transactions and $3.4 million of transmission transactions in the pro forma statement of operations for the year ended December 31, 2016.

(c)           Certain adjustments that are directly related to the merger were made to debt and debt related accounts. These adjustments include the planned extinguishment of the Rice notes and the Rice credit facilities at or near closing. The issuance of $3.0 billion of EQT notes and the planned upsize of EQT’s revolving credit facility were to fund the cash portion of the merger consideration and to

8

support ongoing operations with better interest rates and terms available to EQT as a result of the Company’s investment grade credit rating. The adjustments are as follows:

1.                                      A $1,254.2 million increase to cash reflecting the issuance of $3.0 billion of EQT notes, net of $25.7 million of issuance costs and discounts, repayment of the Rice notes, including call premium, of $1,380.0 million, $35.5 million of accrued interest on the Rice notes, repayment of $298.5 million of outstanding amounts on the Rice Midstream Holdings credit facility and $6.1 million of estimated debt issuance costs for fees related to increasing EQT’s revolving credit facility to support the merger.

2.                                      A $6.1 million increase to deferred financing costs of estimated debt issuance costs for fees related to increasing EQT’s revolving credit facility to support the merger.

3.                                      A $1,295.8 million increase to long term debt reflecting the anticipated issuance of $3.0 billion of EQT notes, net of $25.7 million of issuance costs offset by the repayment of the Rice notes recorded at fair value of $1,380.0 million and the repayment of $298.5 million of outstanding amounts on the Rice Midstream Holdings credit facility.

4.                                      A $2.8 million decrease in interest expense for the period ended September 30, 2017 consisting of the elimination of $76.3 million of Rice historical interest expense and an increase to interest expense of $73.5 million relating to the issuance of the EQT notes at a weighted average interest rate of 3.14% per annum and amortization of associated deferred financing costs and discounts.

5.                                      A $9.3 million pro forma adjustment was made to eliminate the amortization of deferred financing costs related to the Rice notes and the Rice credit facilities for the period ended September 30, 2017.

6.                                      A $31.9 million decrease in interest expense for the year ended December 31, 2016 consisting of the elimination of $129.9 million of Rice pro forma interest expense, including $34.3 million of pro forma Vantage interest expense, and an increase to interest expense of $98.0 million relating to the issuance of the EQT notes at a weighted average interest rate of 3.14% per annum and amortization of associated deferred financing costs and discounts.

7.                                      A $7.5 million pro forma adjustment was made to eliminate the amortization of deferred financing costs related to the Rice notes and the Rice credit facilities for the year ended December 31, 2016.

A one percent change in the assumed interest rate of the EQT notes would increase or decrease the interest expense by $22.5 million and $30.0 million for the nine months ended September 30, 2017 and for the year ended December 31, 2016, respectively.

(d)           To accrue for estimated remaining transaction costs of $217.4 million related to the merger, including underwriting, banking, legal and accounting fees that are not capitalized as part of the merger. The estimated remaining costs are not reflected in the historical September 30, 2017 balance sheets of EQT and Rice, but are reflected in the pro forma balance sheet as an increase to liabilities as they will be expensed by EQT and Rice as incurred. Transaction expenses recognized in the nine months ended September 30, 2017 and their corresponding tax effect have been eliminated in the pro forma statements of operations due to their nonrecurring nature. The Company expects to record an estimated post-combination compensation expense of approximately $140.0 million related to the acceleration of the unvested share-based awards of Rice and other compensation arrangements due to the merger. This amount is excluded from the unaudited pro forma condensed combined statements of operations because it is a charge directly attributable to the merger that would not have a continuing impact on the Company’s operations; however, the amount is reflected as a reduction to retained earnings in the unaudited pro forma balance sheet. The estimated share-based compensation expense related to replacement awards issued to continuing employees as part of the acquisition agreement is immaterial and is not reflected as an adjustment in the unaudited pro forma condensed combined statement of operations.

(e)           Pro forma adjustment to show the impact of the elimination of the Rice equity on the pro forma balance sheet and the elimination of the noncontrolling interest in Rice Energy Operating, LLC and Rice Midstream GP Holdings LP on the pro forma statement of operations for the nine months ended September 30, 2017 and the year ended December 31, 2016.

9

(f)            Pro forma adjustment of historical depreciation, depletion and amortization expense (DD&A) related to the step up of property, plant and equipment to estimated fair value. In addition, this adjustment includes a pro forma adjustment for DD&A to adjust the depreciation on certain Rice midstream assets to EQT’s policy to depreciate gathering pipelines over a 50 year useful life and to depreciate compression and measurement assets over a 25 year useful life.

(g)           A total pro forma adjustment for the amortization of intangibles of $43.5 million and $58.1 million was made for the nine months ended September 30, 2017 and for the year ended December 31, 2016, respectively. The adjustment consisted of a $12.5 million adjustment and a $16.7 million adjustment for the nine months ended September 30, 2017 and year ended December 31, 2016, respectively, for the amortization of the fair value of the customer relationships that were acquired using a 30 year estimated life and straight line method of amortization and a $31.0 million adjustment and $41.4 million adjustment for the nine months ended September 30, 2017 and for the year ended December 31, 2016, respectively, for the amortization of the non-compete agreements using a 3 year estimated life and straight line method of amortization. The adjustment also included a $1.3 million adjustment and a $1.7 million adjustment for the nine months ended September 30, 2017 and the year ended December 31, 2016, respectively, for the impact to noncontrolling interests.

(h)           Pro forma adjustment for elimination of preferred dividends and accretion of redeemable noncontrolling interests related to EQT’s redemption of the Series B preferred interest in Rice Midstream Holdings for $430 million. A pro forma adjustment of $14.4 million for the nine months ended September 30, 2017 was also made to eliminate the loss on embedded derivatives as it relates to the option on the Series B preferred interest which will be redeemed at the merger as reflected in pro forma adjustment (a).

(i)            The pro forma income tax adjustments included in the pro forma statement of operations for the periods ended September 30, 2017 and December 31, 2016 reflect the income tax effects of the pro forma adjustments presented. The tax rate applied to the pro forma adjustments was the statutory federal and apportioned statutory state tax rate, net of the federal benefit of state taxes, applied to pre-tax income, excluding income allocated to noncontrolling interests, as taxes attributable to noncontrolling interests and not borne by EQT. No adjustment has been included in the pro forma statement of operations for potential adjustments to EQT’s valuation allowance on deferred tax assets due to the nonrecurring nature of any such adjustment.

(j)            The following reclassifications were made as a result of the transaction to conform to EQT’s presentation:

1.                                      Reclassification of $32.2 million of long term derivative assets and $31.8 million of long term derivative liabilities to current and an increase of $153.2 million to current derivative assets and liabilities to conform to EQT’s presentation of derivatives.

2.                                      Reclassification of $1.9 million of Rice’s gas collateral account to other assets.

3.                                      Reclassification of $105.9 million of Rice’s royalties payable to accounts payable.

4.                                      Reclassification of $212.4 million of Rice’s accrued capital expenditures to accounts payable.

5.                                      Reclassification of $22.1 million of Rice’s current leasehold payable to other current liabilities.

6.                                      Reclassification of $0.6 million of Rice’s accrued interest to other current liabilities.

7.                                      Reclassification of $222.0 million of Rice’s long-term debt to credit facility borrowings.

8.                                      Reclassification of $13.2 million of Rice’s long-term leasehold payable to other long term liabilities.

10.                               Reclassification on the September 30, 2017 pro forma statement of operations of $29.2 million of Rice’s other revenue to pipeline and net marketing services.

10

11.                               Reclassification on the September 30, 2017 pro forma statement of operations of $121.3 million of Rice’s gain on derivative instruments to gain (loss) on derivatives not designated as hedges.

12.                               Reclassification on the September 30, 2017 pro forma statement of operations of $54.8 million of Rice’s lease operating expenses to production expense.

13.                               Reclassification on the September 30, 2017 pro forma statement of operations of $11.0 million of Rice’s incentive unit expense to selling, general and administrative expense.

14.                               Reclassification on the September 30, 2017 pro forma statement of operations of $8.9 million of Rice’s acquisition expense to selling, general and administrative expense.

16.                               Reclassification on the December 31, 2016 pro forma statement of operations of $24.4 million of Rice’s other revenue to pipeline and net marketing services.

17.                               Reclassification on the December 31, 2016 pro forma statement of operations of $213.9 million of Rice’s loss on derivative instruments to (loss) on derivatives not designated as hedges.

18.                               Reclassification on the December 31, 2016 pro forma statement of operations of $63.6 million of Rice’s lease operating expenses to production expenses.

19.                               Reclassification on the December 31, 2016 pro forma statement of operations of $20.9 million of Rice’s impairment of gas properties to impairment of long lived assets.

20.                               Reclassification on the December 31, 2016 pro forma statement of operations of $51.7 million of Rice’s incentive unit expense to selling, general and administrative expense.

21.                               Reclassification on the December 31, 2016 pro forma statement of operations of $6.1 million of Rice’s acquisition expense to selling, general and administrative expense.

In addition, the combined pro forma financial statements do not reflect the realization of all expected cost savings or other synergies from the merger as a result of restructuring activities and other cost savings initiatives. Although EQT believes cost savings and other synergies will be realized following the business combination, there can be no assurance that cost savings or any other synergies will be achieved in full or at all.

3.                                      Rice’s Unaudited Pro Forma Condensed Combined Statements of Operations

Rice’s unaudited pro forma statement of operations for the year ended December 31, 2016 included in the unaudited pro forma condensed combined statement of operations gives effect to Rice’s acquisition of Vantage and their subsidiaries pursuant to the terms of the Purchase and Sale Agreement dated

11

September 26, 2016 between Rice and Vantage. Rice’s unaudited pro forma combined statement of operations is presented as if Rice had acquired Vantage on January 1, 2016:

(1)                                 Includes Vantage amounts from October 19, 2016 through December 31, 2016.

(2)                                 Represents the amounts on the Vantage Statement of Operations for January 1, 2016 through October 18, 2016.

12

(a)                                 Reflects exploratory costs capitalized by Vantage under the full cost method that would have been charged to exploration expense under the successful efforts method of accounting for oil and gas properties.

(b)                                 Adjustment of historical depreciation, depletion and amortization of Vantage to adjust to Rice’s policy to deprecate midstream assets over a 60 year useful life and to include pro forma provisions for DD&A related to the step up of property, plant and equipment to estimated fair value and application of the successful efforts method of accounting in the determination of the depletion rate.

(d)                                 To reflect tax impact of Vantage results of operations under Rice’s corporate tax structure. The tax rate applied to the pro forma adjustments and Vantage’s untaxed preacquisition net loss was the statutory federal and apportioned statutory state tax rate, net of the federal benefit of state taxes, applied to pre-tax income, excluding income allocated to non controlling interests as taxes attributable to non controlling interests not borne by Rice.

(e)                                  To adjust for historical estimated impact of Vantage on Rice Midstream Holdings noncontrolling interest.

(f)                                   To adjust for historical estimated impact of Vantage on Rice Energy Operating noncontrolling interest.

4.                                      Supplemental Pro Forma Natural Gas, NGLs and Crude Oil Reserves Information

The following tables present the estimated pro forma combined net proved developed and undeveloped, natural gas, NGLs and crude oil reserves as of December 31, 2016, along with a summary of changes in quantities of net remaining proved reserves during the year ended December 31, 2016. The pro forma reserve information set forth below gives effect to the merger as if the transaction had occurred on January 1, 2016.

The following estimated pro forma reserve information is not necessarily indicative of the results that might have occurred had the merger taken place on January 1, 2016 and is not intended to be a

13

projection of future results. Future results may vary significantly from the results reflected because of various factors, including those discussed in the section entitled “Risk Factors.”
