Explanatory Note

This Amendment No. 7 amends and supplements the Schedule 13D filed with the Securities and Exchange Commission on August 19, 2019 (the “Original Schedule 13D,” and as amended, the “Schedule 13D”) relating to the common units representing limited partner interests (the “Common Units”) in Western Midstream Partners, LP, a Delaware master limited partnership (the “Issuer”) beneficially owned by Occidental Petroleum Corporation (“Occidental”), OXY USA Inc. (“OXY USA”), OXY Oil Partners, Inc. (“OOP”), Baseball Merger Sub 2, Inc. (“BMS”), Anadarko Petroleum Corporation (“Anadarko”), Western Gas Resources, Inc. (“WGRI”), APC Midstream Holdings, LLC (“AMH”), WGR Asset Holding Company LLC (“WGRAH”), Anadarko Holding Company (“AHC”), Kerr-McGee Corporation (“KMG”), Kerr-McGee Worldwide Corporation (“KWC”) and Anadarko USH1 Corporation (“AUSH1” and together with Occidental, OXY USA, OOP, BMS, Anadarko, WGRI, AMH, WGRAH, AHC and KWC, the “Reporting Persons”). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Original Schedule 13D and subsequent amendments, as applicable.

The filing of this Amendment No. 7 shall not be construed as an admission that any of the Reporting Persons is for the purposes of Section 13(d) or 13(g) of the Securities Exchange Act of 1934, the beneficial owner of any of the Common Units reported herein. Pursuant to Rule 13d-4, each of the Reporting Persons disclaims all such beneficial ownership in any such Common Units.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

August 2024 Secondary Offering

On August 12, 2024, the Issuer, Western Midstream Holdings, LLC, WGRAH, AUSH1 and Barclays Capital Inc., as underwriter (the “Underwriter”), entered into an Underwriting Agreement (the “Underwriting Agreement”), pursuant to which the Underwriter agreed to purchase 14,139,260 and 4,860,740 Common Units from WGRAH and AUSH1, respectively, at a price of $35.75  per unit.

Pursuant to the Underwriting Agreement, AUSH1 granted the Underwriter an option, exercisable for 30 days, to purchase up to an additional 2,850,000 Common Units at $35.75 per unit. The Underwriter elected to partially exercise the option, and on August 14, 2024, WGRAH and AUSH1 sold 14,139,260 and 5,360,740 Common Units to the Underwriter, respectively.

Pursuant to the Underwriting Agreement, the Issuer, WGRAH, AUSH1 and certain directors and officers of the Issuer have agreed not to sell or otherwise dispose of any Common Units held by them for a period ending 45 days after the date of the Underwriting Agreement without first obtaining the written consent of the Underwriter, subject to certain exceptions.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is filed as an exhibit hereto and incorporated herein by reference.

General

The Reporting Persons acquired the securities described in this Schedule 13D for investment purposes and they intend to review their investments in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

Subject to the lock-up provisions of the Underwriting Agreement, the Reporting Persons may acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions. In addition, the Reporting Persons may engage in discussions with management, the board of directors of the general partner of the Issuer (the “Board”), other securityholders of the Issuer and other relevant parties or encourage, cause or seek to cause the Issuer or such persons to consider or explore extraordinary corporate transactions, such as: a merger, reorganization or take-private transaction that could result in the de-listing or de-registration of the Common Units; security offerings and/or Common Unit repurchases by the Issuer; sales or acquisitions of assets or businesses; changes to the capitalization or dividend policy of the Issuer; or other material changes to the Issuer’s business or corporate structure, including changes in management or the composition of the Board.

To facilitate their consideration of such matters, the Reporting Persons may retain consultants and advisors and may enter into discussions with potential sources of capital and other third parties. The Reporting Persons may exchange information with any such persons pursuant to appropriate confidentiality or similar agreements. The Reporting Persons will likely take some or all of the foregoing steps at preliminary stages in their consideration of various possible courses of action before forming any intention to pursue any particular plan or direction.

Other than as described above, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) and (b) See the information on the cover pages of this Amendment No. 7 to the Schedule 13D, which is incorporated by reference herein.

(c) None of the Reporting Persons, or to the Reporting Persons’ knowledge, none of the Listed Persons, has effected any transactions in the Common Units during the past 60 days, other than as described in Item 4 of this Amendment No. 7 to the Schedule 13D.

(d) The Reporting Persons have the right to receive distributions from, and the proceeds from the sale of, the respective Common Units reported by such persons on the cover pages of the Schedule 13D and in this Item 5.  Except for the foregoing, no other person is known by the Reporting Persons to have the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, Common Units beneficially owned by the Reporting Persons or, to the Reporting Persons’ knowledge, the Listed Persons.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 is hereby amended and supplemented by adding the following:

The description of the Underwriting Agreement in Item 4 above is hereby incorporated by reference into this Item 6. A copy of the Underwriting Agreement is included as an exhibit to this filing.

Item 7. Material to be Filed as Exhibits.

Item 7 of the Schedule 13D is hereby amended and supplemented by inserting the following exhibit:
