Explanatory Note

This Amendment No. 1 to Schedule 13D (this “Amendment No. 1”) relates to the beneficial ownership by the Reporting Persons of the common units representing limited partner interests (the “Common Units”) of Noble Midstream Partners LP, a Delaware limited partnership (the “Issuer”) and amends and supplements the initial statement on Schedule 13D filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on October 5, 2020 (the “Schedule 13D”). This Amendment No. 1 is being filed by the Reporting Persons pursuant to the Joint Filing Statement. Capitalized terms used but not otherwise defined in this Amendment No. 1 shall have the same meanings ascribed to them in the Schedule 13D. Except as specifically provided herein, this Amendment No. 1 does not modify any of the information previously reported in the Schedule 13D.

Item 2 to Schedule 13D is hereby amended to replace the previously filed Schedule I with the Schedule I filed herewith, which is incorporated herein by reference.

Item 3 of the Schedule 13D is hereby amended to add the following paragraph:

In connection with the transaction proposed by the Proposal described in Item 4 of this Amendment No. 1 (which Item 4 is incorporated herein by reference), the Reporting Persons anticipate that the funding for such transaction will consist of shares of common stock of Chevron, par value $0.75 per share (“Chevron Common Stock”), as described in Item 4.

Item 4 of the Schedule 13D is hereby amended to add the following paragraph:

On February 4, 2021, Chevron submitted a proposal (the “Proposal”) to the Board of Directors of the General Partner to acquire, in a merger transaction, all of the Issuer’s outstanding Common Units not already owned by Chevron and its affiliates, in exchange for a to-be-determined fixed exchange ratio of Chevron Common Stock, based on a value of $12.47 per Common Unit. The Proposal is subject to the negotiation and execution of definitive agreements and the requisite approvals. If the transaction is consummated, the Common Units are expected to be delisted from The NASDAQ Market LLC.

While the Proposal remains under consideration and subject to negotiation, the Reporting Persons and their representatives may respond to inquiries from the Issuer and its representatives and engage in discussions and negotiations.

No assurances can be given that the transaction contemplated by Chevron or any other potential transaction involving Chevron and the Issuer will be consummated, or if a transaction is undertaken, as to its terms or timing. Chevron reserves the right to modify or withdraw the Proposal at any time. The Reporting Persons reserve the right to formulate other plans or make other proposals which could result in one or more of the transactions, events or actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, and to modify or withdraw any such plan or proposal at any time.
