Changes from the Preliminary Prospectus Supplement

EQT Corporation will issue and sell an additional series of notes, the Floating Rate Notes, on the terms described herein. Other information presented in the Preliminary Prospectus Supplement is deemed to have changed to the extent affected by the changes described below.

Description of Floating Rate Notes:

The stated maturity of principal for the Floating Rate Notes will be October 1, 2020.

The Floating Rate Notes will bear interest at a floating rate of interest, reset quarterly, from the date of original issuance or from the most recent Interest Payment Date (as defined below) to which interest has been paid or provided for.

The per annum interest rate on the Floating Rate Notes for the period from the issue date to but not including the first Interest Payment Date (as defined below) will be equal to LIBOR on

October 2, 2017, plus 77 basis points (such rate, the “Initial Interest Rate”). Following the initial Interest Period, the per annum interest rate on the Floating Rate Notes for each subsequent Interest Period will be equal to LIBOR as determined on the related LIBOR Determination Date, plus 77 basis points. The interest rate applicable to any day in a given Interest Period will be either the Initial Interest Rate or the interest rate as reset on the immediately preceding Interest Payment Date.

Interest is payable on the Floating Rate Notes quarterly in arrears on January 1, April 1, July 1 and October 1 of each year (each, an “Interest Payment Date”). The initial Interest Payment Date will be January 2, 2018 (the next succeeding business day after January 1, 2018). The amount of interest for each day that the Floating Rate Notes are outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of the Floating Rate Notes outstanding on such day. The amount of interest to be paid on the Floating Rate Notes for each Interest Period will be calculated by adding such Daily Interest Amounts for each day in such Interest Period.

If any Interest Payment Date, other than the maturity date of the Floating Rate Notes, falls on a day that is not a Business Day, the Interest Payment Date will be postponed to the next day that is a Business Day. If the maturity date of the Floating Rate Notes falls on a day that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day, and no interest on such payment will accrue for the period from and after the maturity date. If any such Interest Payment Date (other than the maturity date) is postponed as described above, the amount of interest for the relevant Interest Period will be adjusted accordingly.

The interest payable on the Floating Rate Notes on any Interest Payment Date will be paid to the person in whose name the Floating Rate Notes are registered at the close of business on December 15, March 15, June 15 and September 15, as the case may be, immediately preceding the applicable Interest Payment Date; however, interest payable at maturity will be paid to the person to whom principal is payable.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Notwithstanding the foregoing, the interest rate on a series of Floating Rate Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. In addition, the interest rate on the Floating Rate Notes will in no event be lower than zero.

The Trustee initially will act as the Calculation Agent in respect of the Floating Rate Notes. EQT may change the Calculation Agent without prior notice to or consent of the holders of the Floating Rate Notes. Any agreement between EQT and any calculation agent may provide that no amendment to the provisions of the Floating Rate Notes or the indenture relating to the duties or obligations of such calculation agent may become effective as against such calculation

agent without the prior written consent of such calculation agent. The Calculation Agent will, upon the written request of any holder of Floating Rate Notes, provide the interest rate then in effect with respect to the Floating Rate Notes. All calculations made by the Calculation Agent in the absence of manifest error will be conclusive for all purposes and binding on EQT and the holders of the Floating Rate Notes.

Set forth below is a summary of certain of the defined terms used for purposes of determining the interest rate payable on the Floating Rate Notes.

“Designated LIBOR Page” shall be Bloomberg L.P. page “BBAM” or such other page as may replace Bloomberg L.P. page “BBAM” on that service or any successor service for the purpose of displaying London interbank offered rates for U.S. dollar deposits of major banks.

“Interest Period” means the period from, and including, an Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, except for the initial Interest Period, which will be the period from, and including, the original issue date of the Floating Rate Notes to, but excluding, the Interest Payment Date occurring on January 2, 2018 (the next succeeding business day after January 1, 2018).

“LIBOR” means, with respect to an Interest Period, the rate (expressed as a percentage per annum) for deposits in U.S. dollars for a three-month period beginning on the second London Banking Day after the applicable LIBOR Determination Date that appears on the Designated LIBOR Page as of 11:00 a.m., London time, on such LIBOR Determination Date. If the Designated LIBOR Page does not include such a rate or is unavailable on a LIBOR Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected by EQT, to provide such bank’s offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London time, on such LIBOR Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount of U.S. dollars for a three-month period beginning on the second London Banking Day after such LIBOR Determination Date. If at least two such offered quotations are so provided, the LIBOR rate for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected by EQT, to provide such bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such LIBOR Determination Date, for loans in a Representative Amount in U.S. dollars to leading European banks for a three-month period beginning on the second London Banking Day after such LIBOR Determination Date. If at least two such rates are so provided, the LIBOR rate for the Interest Period will be the arithmetic mean of such rates. If fewer than two such rates are so provided, then the LIBOR rate for the Interest Period will be the rate in effect with respect to the immediately preceding Interest Period.

“LIBOR Determination Date” means, with respect to an Interest Period, the London Banking Day that is two London Banking Days prior to the first day of such Interest Period.

“London Banking Day” is any day on which dealings in U.S. dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market.

“Representative Amount” means a principal amount of not less than $1,000,000 for a single transaction in the relevant market at the relevant time.

In addition to the risk factors set forth in the Preliminary Prospectus Supplement, the following risk factors relate to the Floating Rate Notes:

The amount of interest payable on the Floating Rate Notes is set only once per Interest Period based on the three-month U.S. dollar LIBOR on the applicable LIBOR Determination Date, which rate may fluctuate substantially.

In the past, the level of the three-month U.S. dollar LIBOR has experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the three-month U.S. dollar LIBOR are not necessarily indicative of future levels. Any historical upward or downward trend in the three-month U.S. dollar LIBOR is not an indication that the three-month U.S. dollar LIBOR is more or less likely to increase or decrease at any time, and you should not take the historical levels of the three-month U.S. dollar LIBOR as an indication of its future performance. You should further note that although the actual three-month U.S. dollar LIBOR on an interest payment date or at other times during an Interest Period (as defined herein) may be higher than the three-month U.S. dollar LIBOR on the applicable LIBOR Determination Date, you will not benefit from the three-month U.S. dollar LIBOR at any time other than on the LIBOR Determination Date for such period. As a result, changes in the three-month U.S. dollar LIBOR may not result in a comparable change in the market value of the Floating Rate Notes.

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely affect the value of the Floating Rate Notes.

Regulators and law enforcement agencies in the United Kingdom and elsewhere are conducting civil and criminal investigations into whether the banks that contribute to the British Bankers’ Association (the BBA) in connection with the calculation of daily LIBOR may have been under-reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR.

Actions by the BBA, regulators or law enforcement agencies may result in changes to the manner in which LIBOR is determined or the establishment of alternative reference rates. For example, on July 27, 2017, the U.K. Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. At this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted in the United Kingdom or elsewhere. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the trading market for LIBOR-based securities, including the Floating Rate Notes.
