INFORMATION IN THIS PROSPECTUS SUPPLEMENT
AND THE ACCOMPANYING PROSPECTUS

        This prospectus supplement and the accompanying prospectus are part of a registration statement that EQT filed with the Securities and Exchange Commission (the SEC) using a shelf registration process. Under the shelf registration process, EQT may offer, issue and sell unsecured debt securities which may be senior, subordinated or junior subordinated debt securities, preferred stock and common stock. In the accompanying prospectus, we provide you with a general description of the securities EQT may offer from time to time under our shelf registration statement. In this prospectus supplement, we provide you with specific information about the notes that EQT is selling in this offering. Both this prospectus supplement and the accompanying prospectus include important information about us, EQT's debt securities and other information you should know before investing. This prospectus supplement also adds, updates and changes information contained in the accompanying prospectus. To the extent that any statement that we make in this prospectus supplement is inconsistent with the statements made in the accompanying prospectus, the statements made in the accompanying prospectus are deemed modified or superseded by the statements made in this prospectus supplement. You should read both this prospectus supplement and the accompanying prospectus as well as additional information described under "Where You Can Find More Information" on page S-69 of this prospectus supplement before investing in the notes.

        You should rely only on the information incorporated by reference or provided in this prospectus supplement and the accompanying prospectus or any free writing prospectus prepared by or on behalf of us. Neither we nor the underwriters have authorized anyone to provide you with additional or different information. If anyone provided you with additional or different information, you should not rely on it. Neither we nor the underwriters are making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference is accurate only as of their respective dates. Our business, financial condition, results of operations and prospects may have changed since those dates.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

        Disclosures in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference contain certain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act), and Section 27A of the Securities Act of 1933, as amended (the Securities Act). Statements that do not relate strictly to historical or current facts are forward-looking and usually identified by the use of words such as "anticipate," "estimate," "could," "would," "will," "may," "forecast," "approximate," "expect," "project," "intend," "plan," "believe" and other words of similar meaning in connection with any discussion of future operating or financial matters. Without limiting the generality of the foregoing, forward-looking statements contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference include the matters discussed in the sections captioned "Outlook" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" of EQT's Annual Report on Form 10-K for the year ended December 31, 2016 and EQT's Quarterly Reports on Form 10-Q for the quarters ended March 31, 2017 and June 30, 2017, and the expectations of plans, strategies, objectives and growth and anticipated financial and operational performance of EQT and its subsidiaries, including guidance regarding the Company's strategy to develop its Marcellus, Utica, Upper Devonian and other reserves; drilling plans and programs (including the number, type, feet of pay and location of wells to be drilled and the availability of capital to complete these plans and programs); production sales volumes (including liquids volumes) and growth rates; gathering and transmission volumes; infrastructure programs (including the timing, cost and capacity of the gathering and transmission expansion projects); the cost, capacity, timing of

regulatory approval, and anticipated in-service date of the Mountain Valley Pipeline project; technology (including drilling and completion techniques); monetization transactions, including asset sales, joint ventures or other transactions involving the Company's assets; acquisition transactions; the Company's ability to complete, the timing of, and the Company's financing of the funds required for, the Rice Merger (as defined below); natural gas prices, changes in basis and the impact of commodity prices on the Company's business; reserves; potential future impairments of the Company's assets; projected capital expenditures and capital contributions; the amount and timing of any repurchases under the Company's share repurchase authorization; liquidity and financing requirements, including funding sources and availability; hedging strategy; the effects of government regulation and litigation; and tax position. The forward-looking statements included in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference involve risks and uncertainties that could cause actual results to differ materially from projected results. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. The Company has based these forward-looking statements on current expectations and assumptions about future events. While EQT considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks and uncertainties, many of which are difficult to predict and beyond the Company's control. The risks and uncertainties that may affect the operations, performance and results of the Company's business and forward-looking statements include, but are not limited to, those set forth under Item 1A, "Risk Factors", and elsewhere in EQT's Annual Report on Form 10-K for the year ended December 31, 2016, as updated by Part II, Item 1A, "Risk Factors" in EQT's subsequently filed Quarterly Reports on Form 10-Q.

        Any forward-looking statement speaks only as of the date on which such statement is made, and the Company does not intend to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise.

RISK FACTORS

        Any investment in the notes involves a high degree of risk. You should carefully consider the risks described below and all of the information contained in this prospectus supplement, the accompanying prospectus, any free writing prospectus and the documents incorporated by reference herein and therein before deciding whether to purchase the notes. In addition, you should carefully consider, among other things, the matters discussed under "Risk Factors" in EQT's Annual Report on Form 10-K for the year ended December 31, 2016, and in other documents that EQT subsequently files with the SEC, all of which are incorporated by reference to this prospectus supplement and the accompanying prospectus. The risks and uncertainties described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of the following risks actually occur, our business, financial condition and results of operations would suffer. The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements. See "Disclosure Regarding Forward-Looking Statements."

Risks Related to This Offering

The notes are structurally subordinated to the liabilities of our subsidiaries and effectively subordinated to any existing and future secured debt to the extent of the assets securing any such secured debt. We may not have sufficient funds to fulfill our obligations under the notes.

        The notes are obligations exclusively of EQT. EQT is a holding company and, accordingly, substantially all of our operations are conducted through EQT's subsidiaries. As a result, EQT's debt is "structurally subordinated" to all existing and future debt, trade creditors, and other liabilities of EQT's subsidiaries and "effectively subordinated" to any existing and future secured debt to the extent of the assets securing any such secured debt. EQT's rights, and hence the rights of its creditors, to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise would be subject to the prior claims of that subsidiary's creditors, except to the extent that EQT's claims as a creditor of such subsidiary may be recognized. As a result of the foregoing and due to other factors, EQT may not have sufficient funds to fulfill its obligations under the notes.

The Indentures do not limit the amount of debt that we may incur.

        The Indentures governing the notes will not restrict EQT's or its subsidiaries' ability to incur indebtedness, including a certain amount of secured indebtedness or an unlimited amount of secured indebtedness to the extent the notes are secured equally and ratably with such indebtedness, to pay dividends or make distributions on, or redeem or repurchase our equity securities, or to engage in highly leveraged transactions that would increase the level of our indebtedness.

EQT depends upon its subsidiaries to service its debt.

        EQT's cash flow and its ability to service its debt, including the notes, is dependent upon the earnings of its subsidiaries. EQT's subsidiaries are separate and distinct legal entities. They have no obligation to pay any amounts due under the notes or to provide EQT with funds for its payment obligations. Payment to EQT by its subsidiaries will also be contingent upon its subsidiaries' earnings and other business considerations.

Our substantial indebtedness could adversely affect our financial condition.

        We currently have, and after the completion of this offering, we will continue to have, a significant amount of indebtedness. This significant amount of indebtedness could limit our ability to obtain additional financing for working capital, capital expenditures, stock repurchases, acquisitions, debt service requirements or other purposes. It may also increase our vulnerability to adverse economic,

S-14

---

Table of Contents

market and industry conditions, limit our flexibility in planning for, or reacting to, changes in our business operations or to our industry overall, and place us at a disadvantage in relation to our competitors that have lower debt levels. Any or all of the above events and/or factors could have an adverse effect on our results of operations and financial condition.

EQT may issue additional notes.

        EQT may from time to time without notice to, or the consent of, the holders of any series of notes, create and issue additional notes of such series, which notes will be equal in rank to the notes of that series so that the new notes may be consolidated and form a single series with the existing notes of such series and have the same terms as to status, redemption or otherwise as such notes (except for the issue date and, under certain circumstances, the issue price, the initial interest payment date and the date from which interest thereon will begin to accrue).

Redemption may adversely affect your return on the notes.

        The notes are redeemable at EQT's option, and therefore EQT may choose to redeem the notes at times when prevailing interest rates are relatively low. As a result, you may not be able to reinvest the proceeds you receive from the redemption in a comparable security at an effective interest rate as high as the interest rate on your notes being redeemed.

There is no public market for the notes.

        We can give no assurances concerning the liquidity of any market that may develop for the notes offered hereby, the ability of any investor to sell the notes, or the prices at which investors would be able to sell them. If a market for the notes does not develop, investors may be unable to resell the notes for an extended period of time, if at all. If a market for the notes does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell any of the notes. Consequently, investors may not be able to liquidate their investment readily, and lenders may not readily accept the notes as collateral for loans.

Risks Related to the Rice Merger

The transactions contemplated by the Rice Merger Agreement are subject to conditions, including certain conditions that may not be satisfied, or completed on a timely basis, if at all. Failure to complete the transactions contemplated by the Rice Merger Agreement, including the Rice Merger, could have material and adverse effects on us.

        Completion of the Rice Merger is subject to a number of conditions, including the approval by EQT's shareholders of issuance of EQT's common stock that forms a portion of the Merger Consideration and approval by stockholders of Rice of a proposal to adopt the Rice Merger Agreement, which make the completion and timing of the completion of the transactions uncertain. Also, either EQT or Rice may terminate the Rice Merger Agreement if the Rice Merger has not been consummated by February 19, 2018 or, at either party's discretion—if the only conditions to closing that have not been satisfied or waived by that date are those related to the termination or expiration of any waiting period under the Hart-Scott-Rodino Antitrust Improvements Act or the issuance of an order, decree, ruling, injunction or other action that is in effect and is restraining, enjoining or otherwise prohibiting the consummation of the Rice Merger—May 19, 2018, except that this right to terminate the Rice Merger Agreement will not be available to any party whose material breach of a representation, warranty, covenant or other agreement of such party under the Rice Merger Agreement resulted in the failure of the transactions to be consummated on or before that date.

S-15

Table of Contents

        If the transactions contemplated by the Rice Merger Agreement are not completed, our ongoing business may be adversely affected and, without realizing any of the benefits of having completed the transactions, we will be subject to a number of risks, including the following:

•

we will be required to pay our costs relating to the transactions, such as legal, accounting, financial advisory and printing fees, whether or not the transactions are completed;



•

time and resources committed by our management to matters relating to the transactions could otherwise have been devoted to pursuing other beneficial opportunities;



•

the market price of EQT's common stock could decline to the extent that the current market price reflects a market assumption that the transactions will be completed;



•

if the Rice Merger Agreement is terminated and EQT's board of directors seeks another acquisition, EQT's shareholders cannot be certain that we will be able to find a party willing to enter into a transaction as attractive to us as the acquisition of Rice.

If EQT does not complete the Rice Merger on or prior to May 19, 2018, or if EQT notifies the Trustee that EQT will not pursue the consummation of the Rice Merger, EQT will be required to redeem the notes of each series then outstanding and may not have or be able to obtain all the funds necessary to redeem such notes. In addition, if EQT is required to redeem the notes, you may not obtain your expected return on the redeemed notes.

        EQT may not be able to consummate the Rice Merger within the timeframe specified in the section entitled "Description of Notes—Special Mandatory Redemption." EQT's ability to consummate the Rice Merger is subject to various closing conditions, many of which are beyond our control, and we may not be able to consummate the Rice Merger.

        If (x) the consummation of the Rice Merger does not occur on or before May 19, 2018 or (y) EQT notifies the Trustee that EQT will not pursue the consummation of the Rice Merger, EQT will be required to redeem the notes of each series then outstanding at a redemption price equal to 101% of the principal amount of the notes to be redeemed plus accrued and unpaid interest to, but excluding the Special Mandatory Redemption Date. However, there is no escrow account or security interest for the benefit of the noteholders and it is possible that EQT will not have sufficient financial resources available to satisfy its obligations to redeem the notes required to be redeemed in connection with the Special Mandatory Redemption (as defined herein). In addition, even if EQT is able to redeem the notes pursuant to the provisions relating to the Special Mandatory Redemption, you may not obtain your expected return on the notes to be redeemed in connection therewith and may not be able to reinvest the proceeds from the Special Mandatory Redemption in an investment that results in a comparable return. Your decision to invest in the notes is made at the time of the offering of the notes. You will have no rights under the provisions relating to the Special Mandatory Redemption as long as the Rice Merger is consummated on or prior to May 19, 2018, nor will you have any right to require EQT to repurchase your notes if, between the closing of the notes offering and the closing of the Rice Merger, we experience any changes in our business or financial condition, or if the terms of the Rice Merger or the financing thereof change.

The Rice Merger is subject to the receipt of approvals, consents or clearances from regulatory authorities that may impose conditions that could have an adverse effect on us or, if not obtained, could prevent completion of the transactions.

        Completion of the Rice Merger is conditioned upon the receipt of certain governmental approvals. Although each party has agreed to use their respective reasonable best efforts to obtain the requisite governmental approvals, there can be no assurance that these approvals will be obtained and that the other conditions to completing the Rice Merger will be satisfied. In addition, the governmental

S-16

---

Table of Contents

authorities from which the regulatory approvals are required may impose conditions on the completion of the Rice Merger or require changes to the terms of the Rice Merger or other agreements to be entered into in connection with the Rice Merger Agreement. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying or impeding consummation of the transactions or of imposing additional costs or limitations on us or Rice following completion of the Rice Merger, any of which might have an adverse effect on us or Rice following completion of the Rice Merger.

We and Rice will be subject to business uncertainties while the Rice Merger is pending, which could adversely affect our business.

        In connection with the pendency of the transactions, it is possible that certain persons with whom we and Rice have a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with us or Rice, as the case may be, as a result of the transactions, which could negatively affect our or Rice's revenues, earnings and cash flows, as well as the market price of our respective common stock, regardless of whether the Rice Merger is completed.

        Under the terms of the Rice Merger Agreement, each of we and Rice are subject to certain restrictions on the conduct of our business prior to the effective time of the Rice Merger, which may adversely affect our and Rice's ability to execute certain of our and Rice's business strategies, including the ability in certain cases to enter into contracts, acquire or dispose of assets, incur indebtedness or incur capital expenditures, as applicable. Such limitations could negatively affect our businesses and operations prior to the completion of the transactions.

In connection with the Rice Merger, we will incur or assume significant additional indebtedness, which could adversely affect us, including by decreasing our business flexibility and increasing our interest expense.

        We anticipate a substantial increase in our consolidated indebtedness as a result of the Rice Merger in comparison to our indebtedness on a recent historical basis. This increased indebtedness could have the effect, among other things, of reducing our flexibility to respond to changing business and economic conditions and increasing our interest expense. In addition, the amount of cash required to pay interest on our indebtedness following completion of the Rice Merger and thus the demands on our cash resources, will be greater than the amount of cash required to service our indebtedness prior to the transaction. The increased levels of indebtedness following completion of the Rice Merger could therefore reduce funds available for working capital, capital expenditures, acquisitions and other general corporate purposes and may create competitive disadvantages for us relative to other companies with lower debt levels.

        In connection with the debt financing, it is anticipated that EQT will seek ratings of its indebtedness from one or more nationally recognized credit rating agencies. EQT's credit ratings reflect each rating organization's opinion of EQT's financial strength, operating performance and ability to meet its debt obligations. EQT's credit ratings affect the cost and availability of future borrowings and, accordingly, our cost of capital. There can be no assurance that EQT will achieve a particular rating or maintain a particular rating in the future.

The unaudited pro forma condensed combined financial information in this prospectus supplement is presented for illustrative purposes only and may not be reflective of our operating results and financial condition following completion of the pro forma events.

        The unaudited pro forma condensed combined financial information in this prospectus supplement is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of operations would have been had the pro forma events been completed on the

dates indicated. Further, our actual results and financial position after the pro forma events may differ materially and adversely from the unaudited pro forma condensed combined financial data that is included in this prospectus supplement. The unaudited pro forma condensed combined financial information has been prepared with the assumption that we will be identified as the acquirer under U.S. generally accepted accounting principles and reflects adjustments based upon preliminary estimates of the fair value of assets to be acquired and liabilities to be assumed.

We are expected to incur substantial expenses related to the completion of the transactions.

        The combined company is expected to incur substantial expenses in connection with the completion of the Rice Merger and the transactions contemplated by the Rice Merger Agreement. While we have assumed that a certain level of expenses would be incurred, there are many factors beyond our and Rice's control that could affect the total amount or the timing of the expenses.

USE OF PROCEEDS

        We estimate that the net proceeds from this offering, after deducting underwriters' discounts and estimated offering expenses of approximately $             million, will be approximately $             million. We expect to use the net proceeds from the offering of the notes, together with cash on hand and borrowings under EQT's revolving credit facility, to fund the cash consideration payable by us for the Rice Merger, to pay expenses related to the Rice Merger and the other transactions contemplated by the Rice Merger Agreement (including the Rice Refinancings) and for general corporate purposes. We intend to issue the notes in this offering in lieu of borrowing under the Bridge Facility.

        As of June 30, 2017, borrowings outstanding under the senior secured credit facilities of Rice and Rice Midstream Holdings were $0 and $112.5 million, respectively. We anticipate that, as of October 31, 2017, borrowings under the senior secured credit facilities of Rice and Rice Midstream Holdings will be $75 million and $185 million, respectively. The current borrowings under the senior secured credit facility of Rice Midstream Holdings were incurred for general corporate purposes.

        Interest was incurred on the currently-outstanding borrowings under the senior secured credit facility of Rice Midstream Holdings at a weighted average interest rate of approximately 3.2% for the six months ended June 30, 2017. The senior secured credit facility of Rice has a maturity date of October 19, 2021 and bears interest at LIBOR plus an applicable margin ranging from 225 to 325 basis points, in the case of eurodollar loans, or at a base rate plus an applicable margin ranging from 125 to 225 basis points, in the case of base rate loans, in each case depending on the percentage of borrowing base utilized. The senior secured credit facility of Rice Midstream Holdings has a maturity date of December 22, 2019 and bears interest at LIBOR plus an applicable margin ranging from 225 to 300 basis points, in the case of eurodollar loans, or at a base rate plus an applicable margin ranging from 125 to 200 basis points, in the case of base rate loans, in each case depending on the leverage ratio then in effect.

        Certain affiliates of the underwriters are lenders under the senior secured credit facilities of Rice and Rice Midstream Holdings and, as such, will receive a portion of the net proceeds from this offering pursuant to the repayment of borrowings under such facilities. See "Underwriting (Conflicts of Interest)."

        As of June 30, 2017, there were $900 million of Rice's 6.25% Senior Notes due 2022 outstanding and $400 million of Rice's 7.25% Senior Notes due 2023 outstanding. Rice's 6.25% Senior Notes due 2022 mature on May 1, 2022 and bear interest at a rate of 6.25% per annum. Rice's 7.25% Senior Notes due 2023 mature on May 1, 2023 and bear interest at a rate of 7.25% per annum.

        Certain affiliates of the underwriters hold Rice's 6.25% Senior Notes due 2022 and/or Rice's 7.25% Senior Notes due 2023 and, accordingly, may receive a portion of the net proceeds of this offering in connection with the redemption of those notes.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introduction

        The following unaudited pro forma condensed combined financial statements (the pro forma financial statements) have been prepared to reflect the effects of the Rice Merger on the financial statements of EQT. The unaudited pro forma condensed combined balance sheet (the pro forma balance sheet) is presented as if the Rice Merger had occurred on June 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 six months ended June 30, 2017, are presented as if the Rice 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 Rice 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 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 Rice Merger;



•

assumed redemption of the Series B preferred interest in Rice Midstream Holdings by EQT for $430 million and the related elimination of preferred dividends and accretion of redeemable 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 Rice Merger;



•

planned issuance of $2.0 billion in new EQT notes, with expected maturities of three, five and ten years (the EQT notes), to fund a portion of the cash merger consideration 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 EQT believes the interest rate and terms on the Rice notes and Rice credit facilities are significantly less favorable than what EQT believes it can obtain with traditional debt financing in a capital markets transaction between now and a time at or near closing given the Company's investment grade credit rating and current market conditions;



•

planned upsize of (which EQT completed on July 31, 2017), and borrowing under, EQT's revolving credit facility;



•

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 asset 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 upon certain valuations and other studies that have yet to commence or progress to a stage where there is

EQT CORPORATION
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 Rice Merger on the financial statements of EQT. The pro forma balance sheet is presented as if the Rice Merger had occurred on June 30, 2017. The pro forma statements of operations for the year ended December 31, 2016, and the six months ended June 30, 2017, are presented as if the Rice 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 Rice 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 commence or 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 Rice 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 Rice Merger and the adjustment of the historical book values of Rice assets and liabilities as of June 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 Rice 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 Rice Merger consideration as soon as practicable after completion of the Rice Merger.

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

•

changes in the estimated fair value of the shares of EQT common stock issued as consideration to the Rice stockholders, based on EQT's share price at the effective time of the Rice Merger;



•

finalization of assumed and retired Rice indebtedness;

S-27

Table of Contents

•

changes in the estimated fair value of the Rice assets acquired and liabilities assumed as of the date of the Rice Merger, which could result from changes in future commodity prices, reserve estimates, inclusion of drilling synergies, other changes in cost assumptions, interest rates and other facts and circumstances existing at the closing date of the Rice Merger compared to the date of this prospectus supplement;



•

the tax basis of Rice's assets and liabilities as of the effective time of the Rice Merger;



•

changes in the fair value of the noncontrolling interest attributable to the public unit holders of Rice Midstream Partners LP, based on Rice Midstream Partners LP's share price at the effective time of the Rice Merger; and



•

the risk factors described in "Risk Factors."

        As part of the preliminary price allocation, EQT identified an intangible asset for customer contracts and the related customer relationships in Rice's midstream business. The fair value of the identified intangible asset was determined using the income approach which requires a forecast of the expected future cash flows generated by these customer relationships. 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 Rice Merger and the subsequent merger of the surviving corporation of the Rice Merger with and into an indirect wholly owned limited liability company subsidiary of EQT (pursuant to which the limited liability company subsidiary will survive as an indirect wholly owned subsidiary of EQT), 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 U.S. Internal Revenue Code of 1986,

S-28

as amended (the Code); therefore, Rice's tax basis in its assets and liabilities will carry over to EQT and its subsidiaries 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 Rice Merger creates for EQT shareholders, including additional capital efficiencies from longer laterals and lower development costs on the expanded and concentrated acreage position created by the Rice Merger, and substantial operating and administrative synergies. Differences between the preliminary purchase price allocation and the final purchase price allocation may change the amount of intangible asset and goodwill, if any, actually recognized at the effective time of the Rice Merger.

        Pursuant to the Rice 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 Rice Merger, which would result in the issuance by EQT of approximately 92,198,000 shares of EQT common stock valued at $5,772 million (based on the closing price as of September 1, 2017 of $62.61) 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 Rice 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.

        From June 16, 2017, the last trading date prior to the transaction's initial announcement, to September 1, 2017, the preliminary value of EQT's merger consideration to be transferred had increased by approximately $354.0 million, as a result of the increase in the share price for EQT's common stock from $58.77 to $62.61. The final value of total merger consideration paid by EQT will be determined based on the actual number of EQT shares issued and the market price of EQT's common stock at the effective time of the Rice Merger. A ten percent increase or decrease in the closing price of EQT common stock, as compared to the September 1, 2017 closing price of $62.61, would increase or decrease the total consideration by approximately $577.2 million, assuming all other factors are held constant.

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

        NYMEX strip pricing as of June 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 Rice Merger:

1.

Elimination of $9.7 million of receivables and corresponding payables, consisting of $6.7 million for gathering transactions, $2.5 million for gas sales transactions, and $0.5 million for transmission transactions in the pro forma balance sheet as of June 30, 2017.



2.

Elimination of $19.9 million in revenue and corresponding expenses related to the elimination of $17.1 million of gathering transactions and $2.8 million of transmission transactions in the pro forma statement of operations for the period ended June 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 Rice 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 planned issuance of the EQT notes and the planned upsize of and borrowings on EQT's revolving credit facility are planned to fund the cash portion of the merger consideration and to 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 $1,017.1 million increase to cash reflecting the anticipated issuance of $2.0 billion of EQT notes, net of $12.7 million of issuance costs, $539.6 million drawn on the EQT revolver to fund the cash portion of the merger consideration and ongoing operations, repayment of the Rice notes, including call premium, of $1,377.0 million, $14.2 million of accrued interest on the Rice notes, repayment of $112.5 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 Rice 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 Rice Merger.



3.

A $539.6 million increase to short term debt to reflect the draw on the EQT revolver.



4.

A $497.8 million increase to long term debt reflecting the anticipated issuance of $2.0 billion of EQT notes, net of $12.7 million of issuance costs offset by the repayment of the Rice notes recorded at fair value of $1,377.0 million and the repayment of $112.5 million of outstanding amounts on the Rice Midstream Holdings credit facility.



5.

A $4.5 million decrease in interest expense for the period ended June 30, 2017 consisting of the elimination of $49.9 million of Rice historical interest expense and an increase to interest expense of $45.4 million relating to the issuance of the EQT notes at an assumed weighted average interest rate of 3.65% per annum based on current market conditions and recent pricing for similar issuances by comparable companies, draw on EQT revolver at 2.95% based on the current rate under EQT's revolving credit facility as it was amended on July 31, 2017 and amortization of associated deferred financing costs.



6.

A $4.0 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 June 30, 2017.



7.

A $39.1 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 $90.8 million relating to the issuance of the EQT notes at an assumed weighted average interest rate of 3.65% per annum based on current market conditions and recent pricing for similar issuances by comparable companies, draw on EQT revolver at 2.95% based on the current rate under EQT's revolving credit facility as it was amended on July 31, 2017 and amortization of associated deferred financing costs.

8.

A $6.1 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 $10.0 million and $20.0 million for the six months ended June 30, 2017 and for the year ended December 31, 2016, respectively. A one percent change in the interest rate of the EQT revolver would increase or decrease the interest expense by $2.7 million and $5.4 million for the six months ended June 30, 2017 and year ended December 31, 2016, respectively.

        (d)   To accrue for estimated remaining transaction costs of $82.4 million related to the Rice Merger, including underwriting, banking, legal and accounting fees that are not capitalized as part of the Rice Merger. The estimated remaining costs are not reflected in the historical June 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 six months ended June 30, 2017 and their corresponding tax effect have been eliminated in the pro forma statements of operations due to their nonrecurring nature.

        (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 on the pro forma statement of operations for the six months ended June 30, 2017 and the year ended December 31, 2016.

        (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)   As part of the preliminary price allocation, EQT identified intangible assets related to Rice's midstream business. This pro forma adjustment reflects the amortization of the fair value of the intangible assets acquired using a 30 year estimated life and a straight line method of amortization.

        (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 $15.4 million for the six months ended June 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 Rice 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 June 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.
