On June 20, 2018, EQT Midstream Partners, LP (EQM) entered into an Underwriting Agreement (Underwriting Agreement) with Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wells Fargo Securities, LLC, Deutsche Bank Securities Inc., and PNC Capital Markets LLC, as representatives of the underwriters named therein (Underwriters), relating to the public offering (Offering) of $1,100 million aggregate principal amount of EQM’s 4.75% Senior Notes due 2023 (the 2023 Notes), $850 million aggregate principal amount of EQM’s 5.50% Senior Notes due 2028 (the 2028 Notes), and $550 million aggregate principal amount of EQM’s 6.50% Senior Notes due 2048 (the 2048 Notes, and together with the 2023 Notes and the 2028 Notes, the Notes) at prices to the public of 99.761%, 99.538% and 99.055% of the face amount of the Notes, respectively.

The Offering closed on June 25, 2018. EQM used a portion of the net proceeds from the Offering to repay the amounts outstanding under EQM’s 364-day term loan facility and intends to use the remainder of the net proceeds for general partnership purposes. In addition, if the proposed merger between EQM and Rice Midstream Partners LP (NYSE: RMP) (RMP) is consummated, EQM intends to use a portion of the net proceeds from the Offering to repay the amounts outstanding under RMP’s revolving credit facility.

The Offering was made pursuant to EQM’s shelf registration statement on Form S-3 (File No. 333-212362), which became effective upon filing on June 30, 2016 (Registration Statement), and pursuant to the prospectus supplement dated June 20, 2018 (Prospectus Supplement), filed with the Securities and Exchange Commission (Commission) pursuant to Rule 424(b) of the Securities Act of 1933, as amended (Securities Act).

The Underwriting Agreement contains customary representations, warranties and agreements of EQM, and customary conditions to closing, obligations of the parties and termination provisions. EQM has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Underwriters may be required to make because of any of those liabilities.

The Underwriting Agreement and the above descriptions have been included to provide investors and security holders with information regarding the terms of the Underwriting Agreement.  They are not intended to provide any other factual information about EQM, its general partner or their respective subsidiaries, affiliates, businesses or equity holders.  The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of that agreement and as of specific dates; were solely for the benefit of the parties to the Underwriting Agreement; and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other as a way of allocating contractual risk between them that differ from those applicable to investors.  Moreover, the subject matter of the representations and warranties are subject to more recent developments.  Accordingly, investors should be aware that these representations, warranties and covenants or any description thereof alone may not describe the actual state of affairs of EQM, its general partner, or their respective subsidiaries, affiliates, businesses or equity holders as of the date they were made or at any other time.

The foregoing description of the Underwriting Agreement is not complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and incorporated in this Item 1.01 by reference.

The Notes were issued under an Indenture, dated as of August 1, 2014 (Base Indenture), by and among EQM, as issuer, certain subsidiaries of EQM and The Bank of New York Mellon Trust Company, N.A., as trustee (Trustee), as amended and supplemented by (i) in the case of the 2023 Notes, the Third Supplemental Indenture, dated as of June 25, 2018 (the Third Supplemental Indenture), (ii) in the case of the 2028 Notes, the Fourth Supplemental Indenture, dated as of June 25, 2018 (the Fourth Supplemental Indenture) and (iii) in the case of the 2048 Notes, the Fifth Supplemental Indenture, dated as of June 25, 2018 (the Fifth Supplemental Indenture and, together with the Third Supplemental Indenture and the Fourth Supplemental Indenture, the Supplemental Indentures), by and between EQM and the Trustee, setting forth the specific terms applicable to the Notes. The Base Indenture, as amended and supplemented by the Supplemental Indentures, is referred to herein as the Indenture. The Indenture contains covenants that limit EQM’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of EQM’s assets.

Item 1.02                                           Termination of a Material Definitive Agreement.

On June 25, 2018, EQM applied a portion of the proceeds from the Offering to prepay the amounts outstanding under that certain 364-Day Term Loan Agreement, dated as of April 25, 2018 (the Term Loan Agreement), among EQM, the lenders party thereto (the Lenders), and Wells Fargo Bank, National Association, as administrative agent, and terminated all unused commitments outstanding thereunder.  The Term Loan Agreement initially provided a $2.5 billion 364-day unsecured multi-draw term loan facility.  The Term Loan Agreement included mandatory prepayment and commitment reduction requirements related to EQM’s receipt of net cash proceeds from certain debt transactions (including the net cash proceeds received in connection with the issuance of the Notes), equity issuances, asset sales and joint venture distributions. Affiliates of certain of the Underwriters are lenders and/or agents under the 364-day term loan facility and therefore will receive a substantial portion of the net proceeds from the Offering. In addition, in the ordinary course of their respective businesses, certain of the Lenders and the other parties to the Term Loan Agreement and their respective affiliates have engaged, and may in the future engage, in commercial banking, investment banking, financial advisory or other services with EQM and its affiliates for which they have in the past and/or may in the future receive customary compensation and expense reimbursement.
