Westerman LP received the Common Units reported in this Schedule 13D as part of the consideration under that certain Stock Purchase Agreement (the "Purchase Agreement"), dated November 29, 2025, among the Issuer, USA Compression Partners, LLC, a wholly owned subsidiary of the Issuer (the "Buyer"), Westerman LP, J-W Energy Company ("J-W Energy") and J-W Power Company, pursuant to which the Buyer agreed to purchase all of the issued and outstanding capital stock of J-W Energy from Westerman LP for an aggregate purchase price of approximately $860.0 million, subject to certain customary adjustments as set forth in the Purchase Agreement (the "Acquisition"), consisting of (i) $430.0 million of cash and (ii) Common Units of the Issuer with a value of approximately $430.0 million. The Acquisition closed on January 12, 2026 (the "Closing"). The reported beneficial ownership in this Schedule 13D reflects Common Units issued to Westerman LP in book entry form at Closing. No rights to acquire additional Common Units within 60 days of the date hereof are held by the Reporting Persons or any Governing Person. Pursuant to the Purchase Agreement, any purchase price adjustments are addressed through Adjustment Common Units (as defined in the Purchase Agreement) already issued and subject to surrender mechanics, and therefore no additional units are deemed beneficially owned within 60 days. Indemnification Reserve Common Units (as defined in the Purchase Agreement) were issued at Closing and are included, notwithstanding contractual release and legend removal milestones.

The Reporting Persons acquired the Common Units reported in this Schedule 13D for investment purposes as part of the consideration payable in connection with the Acquisition described in Item 3. The Reporting Persons intend to continue to evaluate the Issuer's business, prospects and financial condition, the market for the Common Units, monetary and stock market conditions and other further developments. Depending upon, among other things, the factors set forth in this Item 4, the Reporting Persons reserve their right to review the investment in the Issuer on a continuing basis including the right to (i) dispose of all or part of its investment in the Common Units at any time, (iii) acquire additional Common Units by tender offer, in the open market, in private transactions or otherwise, (iv) propose a merger or similar business combination involving the Issuer or its affiliates, or (v) take any other action with respect to the Issuer. Except as set forth in this Item 4, neither of the Reporting Persons nor, to the Reporting Persons' knowledge, any Governing Person, has any present plans or proposals that relate to or that would result in any of the following actions: (a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) Any material change in the present capitalization or dividend policy of the Issuer; (f) Any other material change in the Issuer's business or corporate structure; (g) Changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) Any action similar to any of those enumerated above.

The aggregate percentage of Common Units reported beneficially owned by the Reporting Persons is based upon 140,860,794 Common Units outstanding, which is 122,685,471 Common Units outstanding as of October 31, 2025 according to the Issuer's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2025 filed by the Issuer with the U.S. Securities and Exchange Commission on November 5, 2025 plus the issuance of the 18,175,323 Common Units reported herein. Pursuant to Rule 13d-3 promulgated under the Act, each of the Reporting Persons may be deemed to be the beneficial owner of 18,175,323 Common Units, which constitutes approximately 12.9% of the Issuer's outstanding Common Units. Except as set forth in this Schedule 13D, to the Reporting Persons' knowledge, none of the Governing Persons is the beneficial owners of any Common Units.

By virtue of its position as the general partner of Westerman LP, Westerman GP may be deemed to share voting and dispositive power with respect to the 18,175,323 Common Units held by Westerman LP. Westerman GP disclaims beneficial ownership of such securities except to the extent of its pecuniary interest therein.

Other than as described in this Schedule 13D and the Purchase Agreement, neither the Reporting Persons nor any Governing Person has effected any transactions in the Issuer's Common Units during the past 60 days.

Purchase Agreement. Under Section 8.9 and Section 8.10 of the Purchase Agreement, Westerman LP agreed that, without the prior written consent of the Issuer (as applicable), it will not transfer any equity consideration Common Units during the "Restricted Period," subject to enumerated "Permitted Transfers." The Restricted Period runs (i) for 50% of the equity consideration Common Units until six months after Closing and (ii) for the remaining 50% until twelve months after Closing. In addition, (A) Adjustment Common Units (as defined in the Purchase Agreement and with a value of $20,000,000) cease to be restricted following the final post closing purchase price adjustment and legend removal, and (B) Indemnification Reserve Common Units (as defined in the Purchase Agreement and with a value of $60,000,000) are released from restrictions in tranches at twelve months and fifteen months after Closing, with any remaining reserve Common Units released upon final resolution of claims, in each case together with related legend removal mechanics. These restrictions are in addition to transfer restrictions under securities laws and any legends required by the Issuer's partnership agreement or the Purchase Agreement. Registration Rights Agreement. Pursuant to the Registration Rights Agreement entered into on January 12, 2026, the Issuer has granted Westerman LP certain rights to require the Issuer to file and maintain the effectiveness of a registration statement with respect to the resale of the Common Units issued as the Unit Consideration (as defined in the Purchase Agreement), and under certain circumstances, to require the Issuer to initiate underwritten offerings for the Common Units to be issued as the Unit Consideration. Board Observer Rights Agreement. Pursuant to the Board Observer Rights Agreement entered into on January 12, 2026, from the date of the Closing until the first anniversary thereof, Westerman LP is entitled to appoint one non-voting observer to the board of directors of the general partner of the Issuer (the "Board Observer"). In no event shall the Board Observer (i) be deemed to be a member of the board of directors of the Issuer, (ii) have or be deemed to have, or otherwise be subject to, any duties (fiduciary or otherwise) to the Issuer or its common unitholders, or (iii) have the right to vote on, or consent to, any matters presented to the board of directors of the Issuer or propose or offer any motions or resolutions to the board of directors of the Issuer.
