Item 5.01 Changes in Control of Registrant.

Effective November 22, 2017, Hess Infrastructure Partners LP (“HIP”), the sponsor of Hess Midstream Partners LP (the “Partnership”), amended and restated its existing credit agreement, dated as of July 1, 2015 (as so amended and restated, the “Amended and Restated Credit Agreement”), in connection with the closing of an offering by HIP of $800 million in aggregate principal amount of senior unsecured notes of HIP to qualified institutional buyers in the United States pursuant to Rule 144A and outside the United States to non-U.S. persons in compliance with Regulation S under the Securities Act of 1933, as amended.

The Amended and Restated Credit Agreement, among other things, (i) reduced the principal amount of HIP’s term loan facility to $200 million; (ii) increased the commitments under HIP’s undrawn revolving credit facility to $600 million; and (iii) extended the maturity date of these term loan and revolving credit facilities to November 2022. Pursuant to the Amended and Restated Credit Agreement and related collateral agreements (collectively, the “Bank Loan Documents”), HIP has pledged its direct and indirect ownership interests in Hess Midstream Partners GP LP, the general partner of the Partnership (the “General Partner”), and Hess Midstream Partners GP LLC, the general partner of the General Partner (together with the General Partner and HIP, the “Bank Loan Parties”) to the lenders under the Amended and Restated Credit Agreement. In addition, the General Partner has pledged all of its incentive distribution rights of the Partnership. If the Bank Loan Parties default on any of their obligations under the Bank Loan Documents, the lenders could exercise their rights under the Bank Loan Documents, which could result in a future change of control of the Partnership.
