Item 1. Security and Issuer.

This Amendment No. 1 to Schedule 13D (Amendment No. 1) amends and supplements or restates (where indicated) the statement on Schedule 13D originally filed with the Securities and Exchange Commission (the Commission) on November 14, 2018 (Schedule 13D), and relates to common units representing limited partner interests (Common Units) in EQGP Holdings, LP, a Delaware limited partnership (the Issuer). The principal executive offices of the Issuer are located at 625 Liberty Avenue, Suite 2000, Pittsburgh, Pennsylvania 15222. Capitalized terms used in this Amendment No. 1 and not defined herein shall have the meanings ascribed to them in Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of Schedule 13D is hereby amended and supplemented by adding the following:

As further described below in response to Item 4, the Common Units that will be acquired by the Reporting Persons pursuant to the Private Purchases and the exercise of the Limited Call Right described in Item 4 below have not been acquired by the Reporting Persons as of the date of this filing, and thus no funds have been used for this purpose. The Reporting Persons estimate that the total amount of funds necessary to purchase all the outstanding Common Units that ETRN and its affiliates do not already own pursuant to the Unit Purchase Agreements and the exercise of the Limited Call Right described in Item 4 below, and to pay fees and expenses in connection the Private Purchases and the exercise of the Limited Call Right, will be approximately $539.4 million. ETRN has entered into a commitment letter (the Debt Commitment Letter) with Goldman Sachs Bank USA, Guggenheim Securities, LLC and certain financing sources party thereto (Goldman Sachs Bank USA and such financing sources, the Commitment Parties) pursuant to which the Commitment Parties have committed to provide ETRN with a secured term loan B facility of up to an aggregate principal amount of $650 million (the Term Facility). The Term Facility will be available to ETRN to finance, among other things, the Private Purchases, the exercise of the Limited Call Right and the payment of associated fees and expenses, subject to customary conditions contained in the Debt Commitment Letter, including, without limitation, (1) the execution and delivery of definitive documentation, (2) the substantially concurrent consummation of the Private Purchases and (3) since November 12, 2018, there not having occurred a material adverse effect on the business, operations or financial condition of ETRN and its subsidiaries, taken as a whole.

Item 4. Purpose of Transaction.

Item 4 of Schedule 13D is hereby amended and supplemented by adding the following paragraphs after the first paragraph thereof:

On November 29, 2018, ETRN entered into written agreements (the Unit Purchase Agreements) with (i) funds managed by Neuberger Berman Investment Adviser LP (Neuberger Berman), pursuant to which ETRN will acquire 5,200,000 Common Units for $20.00 per Common Unit (the Purchase Price), (ii) funds managed by Goldman Sachs Asset Management, L.P. (GSAM), pursuant to which ETRN will acquire 1,865,020 Common Units for the Purchase Price, (iii) funds managed by Cushing Asset Management LP (Cushing), pursuant to which ETRN will acquire 920,130 Common Units for the Purchase Price, (iv) funds managed by Kayne Anderson Capital Advisors, L.P. (Kayne Anderson), pursuant to which ETRN will acquire 1,363,974 Common Units for the Purchase Price, and (v) ZP Energy Fund, L.P. (collectively with Neuberger Berman, GSAM, Cushing and Kayne Anderson, the Selling Unitholders), pursuant to which ETRN will acquire 3,414,168 Common Units for the Purchase Price. The aggregate consideration to be paid by ETRN pursuant to the Unit Purchase Agreements is $255,265,840. In addition, ETRN agreed to purchase from the Selling Unitholders any additional Common Units acquired by the Selling Unitholders after the date of the Unit Purchase Agreements for the Purchase Price. The transactions contemplated by the Unit Purchase Agreements (the Private Purchases) are expected to be completed at 9:00 a.m., Eastern Standard Time, on December 31, 2018, unless ETRN delivers written notice to the Selling Unitholders no later than one calendar day prior to December 31, 2018 specifying a later date (which later date is no more than 30 days following December 31, 2018).

Following the consummation of the Private Purchases, ETRN and its affiliates would own more than 95% of the outstanding Common Units. On that basis, ETRN will be entitled to, and is committing that it will promptly, but in any event not more than 90 days following the consummation of the Private Purchases, exercise the limited call right provided for in Section 15.1(a) of the Partnership Agreement (the Limited Call Right), pursuant to which ETRN will purchase any and all outstanding Common Units at a price per Common Unit equal to the greater of (i) the average of the daily closing price per Common Unit for the 20 consecutive trading days immediately prior to the date three business days prior to the date that the notice of exercise of the Limited Call Right is delivered pursuant to the Partnership Agreement and (ii) the highest price paid by the General Partner or any of its affiliates for any such Common Unit purchased during the 90-day period preceding the date that such notice is mailed, and upon the terms and subject to the conditions set forth in Section 15.1 of the Partnership Agreement. After giving effect to the exercise of the Limited Call Right, ETRN and its affiliates will own all the outstanding Common Units. As a result, following the exercise of the Limited Call Right, the Issuer will cease to be a public company, registration of the Issuer under the Securities Exchange Act of 1934, as amended (the Exchange Act), will be terminated, and the Common Units will cease to be listed on the New York Stock Exchange.

Additionally, ETRN has proposed to the board of directors of the EQM General Partner a transaction pursuant to which, subject to the ETRN’s acquiring all of the outstanding Common Units pursuant to the Private Purchases and the exercise of the Limited Call Right, a subsidiary of EQM will merge with and into the Issuer, with the Issuer surviving as a wholly-owned subsidiary of EQM. In the merger, (i) ETRN’s noneconomic general partner interest in the Issuer will be converted into a noneconomic general partner interest in EQM, (ii) ETRN’s economic interests in the Issuer will be converted into a combination of EQM Common Units and Payment-in-Kind units in EQM (EQM PIK Units) and (iii) the incentive distribution rights and economic general partner interest in EQM held by the Issuer will be cancelled (the Proposed IDR Transaction). The aggregate number of EQM Common Units and EQM PIK Units issued by EQM in the Proposed IDR Transaction would be 95 million. The board of directors of the EQM General Partner has delegated the authority to review, evaluate and negotiate the Proposed IDR Transaction to its conflicts committee.

The foregoing description of the Private Purchases and the Limited Call Right does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Schedule 13E-3 and the Disclosure Statement attached thereto as Exhibit (a)(3) filed by ETRN with the Commission on November 30, 2018, which is incorporated herein by reference.

Item 4(j) of Schedule 13D is hereby amended and restated in its entirety as follows:

(j) Other than the Private Purchases, the Limited Call Right and the Proposed IDR Transaction, as of the date of this Amendment No. 1, the Reporting Persons have not formulated any definitive plan or proposal relating to or

which would result in any of the matters specified in clauses (a) through (i) of Item 4 of Schedule 13D with respect to the Issuer or its subsidiaries. There can be no assurance that ETRN’s proposal to pursue the Proposed IDR Transaction will result in a transaction of interest to the Reporting Persons or the Issuer, or as to the terms of such transactions. The Reporting Persons undertake no obligation to make additional disclosures in connection with the matters described herein except to the extent required by law.

Item 5. Interest in Securities of the Issuer.

Item 5 of Schedule 13D is hereby amended and restated in its entirety as follows:

(a) (1) As of November 30, 2018, the number of Common Units issued and outstanding is 302,470,474. As of November 30, 2018, EMH is the record and beneficial owner of 36,293,766 Common Units, which represent approximately 12.0% of the outstanding Common Units.
