Explanatory Note: This Amendment No. 1 (the “Amendment”) amends and supplements the Statement on Schedule 13D filed on September 20, 2016 with the Securities and Exchange Commission (the “Commission”) relating to the common units (“Common Units”) representing limited partner interests in Noble Midstream Partners LP (the “Issuer” or “Partnership”), a Delaware limited partnership (such Schedule 13D, the “Original Schedule 13D”). The Original Schedule 13D is hereby amended and supplemented by Noble Energy, Inc., a Delaware corporation (“Noble”) and (ii) NBL Midstream, LLC, a Delaware limited liability company (“NBL Midstream,” and together with Noble, the “Reporting Persons”). Unless set forth below, all previous Items of the Original Schedule 13D are unchanged. Capitalized terms used herein which are not defined herein have the meanings set forth in the Original Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule is hereby amended to read in its entirety as follows:

In December 2014, Noble formed the Issuer to own, operate, develop and acquire a wide range of domestic midstream infrastructure assets. Currently, the Issuer’s operating areas of focus are the Denver-Julesburg Basin in Colorado and the Delaware Basin, within the Permian Basin, in Texas. Noble intends for the Issuer to become its primary vehicle for domestic midstream operations in the onshore United States outside of the Marcellus Shale in the northeastern United States.

On September 20, 2016 the Issuer completed an initial public offering of 14,375,000 Common Units, including 1,875,000 Common Units issued pursuant to the underwriters’ overallotment option (the “IPO”). In connection with the completion of the IPO, Noble; the Issuer; NBL Midstream; NBL Midstream Holdings LLC (“NBL Midstream Holdings”); Noble Midstream GP LLC (the “General Partner”); Noble Midstream Services, LLC (“Midstream Services”); Blanco River DevCo LP (the “Blanco River DevCo”); Colorado DevCo GP LLC, Green River DevCo GP LLC, Gunnison River DevCo GP LLC, Laramie River DevCo GP LLC, San Juan River Devco GP LLC and Blanco River DevCo GP LLC (the “GP Subsidiaries”), entered into a contribution, conveyance and assumption agreement, dated September 20, 2016 (the “Original Contribution Agreement”). Pursuant to the Original Contribution Agreement (a) Midstream Services distributed to NBL Midstream its (i) general partner interest in the General Partner, (ii) limited partner interest in the Issuer and (iii) limited partner interests in Blanco River DevCo, Colorado River DevCo LP (“Colorado River DevCo”), Green River DevCo LP, Gunnison River DevCo LP, and San Juan River DevCo LP, (b) the Issuer redeemed the 1% general partner interest in the General Partner and the General Partner issued a non-economic general partner interest; and (c) NBL Midstream contributed to the Issuer 100% of the membership interests in Midstream Services in exchange for (i) 1,527,584 Common Units and 15,902,584 Subordinated Units, (ii) all of the incentive distribution rights of the Issuer and (iii) the right to receive a portion of the net proceeds of the offering of the Common Units. Each Subordinated Unit will convert into one Common Unit at the end of the subordination period, as described in the Prospectus.

On June 26, 2017, pursuant to the certain Contribution Agreement (the “Contribution Agreement”), dated June 20, 2017, by and among the Partnership, the General Partner, Midstream Services, NBL Midstream and Blanco River DevCo GP LLC, a Delaware limited liability company and wholly owned subsidiary of Midstream Services (“Blanco River DevCo GP”), NBL Midstream contributed to the Partnership (i) the remaining 20% limited partner

interest in Colorado River DevCo and (ii) a 15% limited partner interest in Blanco River DevCo (collectively, (i) and (ii) are referred to herein as the “Contributed Assets”). In consideration for the acquisition of the Contributed Assets, the Partnership agreed to pay NBL Midstream total aggregate consideration of $270 million, consisting of (i) consideration of $245 million in cash (the “Cash Consideration”) and (ii) 562,430 Common Units issued to NBL Midstream (the “Transaction”).

Item 4. Purpose of the Transaction.

Item 4 of the Schedule is hereby amended and restated in its entirety as follows:

The Reporting Persons acquired the LP Units solely for investment purposes.

The following describes any other plans or proposals that any Reporting Person may have with respect to the matters set forth in Item 4(a)-(j) of Schedule 13D:

(a) The Reporting Persons may make additional purchases or other acquisitions of Common Units either in the open market or in privately negotiated transactions depending on the Partnership’s business, prospects and financial condition, the market for the Common Units, general economic conditions, money and stock market conditions and other future developments. As disclosed in the Annual Report on Form 10-K of the Issuer filed with the SEC on February 14, 2017, the Partnership has a right of first refusal with respect to, and may acquire, additional assets from Noble. In addition, Noble has indicated that it intends to use the Partnership as its primary vehicle for midstream operations in the onshore United States outside of the Marcellus Shale in the northeastern United States. Subject to market and other conditions, the Partnership intends to finance drop-downs from Noble through a combination of debt and equity securities, including commercial debt facilities and public and private offerings of debt and equity securities.

(b) None.

(c) None.

(d) The General Partner, which has sole responsibility for conducting the Partnership’s business and managing its operations, is ultimately controlled by Noble. Some of Noble’s executive officers and directors also serve as executive officers or directors of the General Partner. Neither the General Partner nor its board of directors will be elected by the Partnership’s unitholders. Noble has the ability to elect all the members of the board of directors of the General Partner.

(e) Subject to the restrictions contained in the Partnership Agreement, Noble, as the ultimate owner of the General Partner of the Partnership, exercises control over the amount of distributions declared by the Partnership and may cause the Partnership to changes its capitalization, through the issuance of debt or equity securities, from time to time in the future. Noble has no current intention of changing the present capitalization or distributions of the Partnership.

(f) -(j) None.

The Reporting Persons may change their plans or proposals in the future.
