Item 1. Security and Issuer.

This Amendment No. 3 to Schedule 13D (Amendment No. 3) 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, as amended by Amendment No. 1 to Schedule 13D filed with the Commission on November 30, 2018 and as amended by Amendment No. 2 to Schedule 13D filed with the Commission on January 3, 2019 (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. 3 and not defined herein shall have the meanings ascribed to them in Schedule 13D.

Item 2. Identity and Background.

Item 2(a) of Schedule 13D is hereby amended by amending and restating the second paragraph as follows:

Gathering Holdings is a limited partner of the Issuer holding approximately 87.9% of the outstanding Common Units, and is the sole stockholder of EQM GP Corporation, a Delaware corporation and limited partner of the Issuer holding approximately 0.1% of the outstanding Common Units (GP Corporation). Gathering Holdings is also the sole member of EQGP Services, LLC, a Delaware limited liability company and the general partner of the Issuer (the General Partner). EMH is also a limited partner of the Issuer holding approximately 12.0% of the outstanding Common Units. ETRN is a publicly traded company and the sole member of Gathering Holdings and EMH. Gathering Holdings and EMH are manager-managed limited liability companies with boards of managers. ETRN is a corporation with a board of directors. The Reporting Persons are hereby filing a joint Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of Schedule 13D is hereby amended by replacing the last sentence of the twelfth paragraph thereof with the following:

Proceeds of such loans were also used to fund the purchase of additional Common Units pursuant to the exercise of the Limited Call Right (as defined below) and to pay fees, costs and expenses in connection therewith and may be used for other general corporate purposes.

Item 3 of Schedule 13D is hereby amended and supplemented by replacing the last paragraph thereof with the following:

Following the Initial Closing, the Reporting Persons owned more than 95% of the outstanding Common Units. On that basis, on December 31, 2018, ETRN exercised the limited call right provided for in Section 15.1(a) of the Partnership Agreement (the Limited Call Right), pursuant to which ETRN purchased all outstanding Common Units (other than those owned by the Reporting Persons) at a price per Common Unit equal to $20.00. The Limited Call Right was completed on January 10, 2019. On January 10, 2019, immediately following the completion of the Limited Call Right, ETRN contributed the Common Units acquired pursuant to the Limited Call Right to Gathering Holdings. The purchase of the Common Units pursuant to the Limited Call Right and associated fees and expenses were financed out of the proceeds of borrowings under the Term Facility.

After giving effect to the exercise of the Limited Call Right, ETRN and its affiliates own all the outstanding Common Units. As a result, the Common Units will be delisted from the New York Stock Exchange, and the Issuer’s reporting obligations under the Securities Exchange Act of 1934, as amended (the Exchange Act), will be terminated.

Item 4. Purpose of Transaction.

Item 4 of Schedule 13D is hereby amended by (i) deleting the second and third paragraphs thereof in their entirety and (ii) by deleting the word “additionally” from, and making corresponding punctuation changes to, the first sentence of the fourth paragraph thereof.

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

(j) Other than the Proposed IDR Transaction, as of the date of this Amendment No. 3, 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 (the Enumerated Matters). 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.
