AMENDMENT NO. 2 TO

STATEMENT ON SCHEDULE 13D

This Amendment No. 2 to Schedule 13D (the “Amendment”) is being filed by Spartan Energy Holdco LLC (“Spartan Holdco”), Spartan Energy Partners LP (“Spartan LP”) and Spartan Energy Partners GP LLC (“Spartan GP”) to amend and supplement the Schedule 13D that was filed on February 8, 2021 (the “Original Schedule 13D”), as amended and supplemented by Amendment No. 1 to Schedule 13D filed on November 18, 2021 and this Amendment (the Original Schedule 13D as so amended, the “Schedule 13D”). Capitalized terms used in this Amendment and not defined herein have the respective meanings ascribed to such terms in the Original Schedule 13D.

Item 2.

Identity and Background.

Item 2 of the Schedule 13D is hereby amended and restated as follows:

This Amendment is being filed by the following entities (each a “Reporting Person” and collectively, the “Reporting Persons”):

CSI Compressco Investment LLC (“CSI Investment”)

CSI Compressco GP LLC (“Compressco GP”)

Spartan Energy Holdco LLC (“Spartan Holdco”)

Spartan Energy Partners LP (“Spartan LP”)

Spartan Energy Partners GP LLC (“Spartan GP”)

Each of the Reporting Persons is organized under the laws of the state of Delaware. The principal business address of each of the Reporting Persons is c/o Spartan Energy Partners LP, 1735 Hughes Landing Blvd., Suite 200, The Woodlands, TX 77380. The Reporting Persons are principally engaged in the business of providing oil and gas services.

The directors and the executive officers of Compressco GP and Spartan GP (the “Related Persons”) are set forth in Schedule I hereto, including each Related Person’s present principal occupation, which is incorporated herein by reference.

During the last five years, none of the Reporting Persons nor any Related Person (i) has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4.

Purpose of Transaction

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

On December 19, 2023, the Issuer, Compressco GP, Kodiak Gas Services, Inc., a Delaware corporation (“Kodiak”), Kodiak Gas Services, LLC, a Delaware limited liability company and indirect, wholly owned subsidiary of Kodiak (“Kodiak Services”), Kick Stock Merger Sub LLC, a Delaware limited liability company and indirect, wholly owned subsidiary of Kodiak (“Stock Merger Sub”), Kick GP Merger Sub LLC, a Delaware limited liability company and direct, wholly owned subsidiary of Kodiak Services (“GP Merger Sub”), and Kick LP Merger Sub, LLC, a Delaware limited liability company and direct, wholly owned subsidiary of Kodiak Services (“Unit Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”).

Upon the terms and subject to the conditions of the Merger Agreement, Stock Merger Sub will merge with and into the Issuer (the “Initial LP Merger” and the effective time of such merger, the “Initial Effective Time”), with the Issuer surviving the Initial LP Merger (the “Initial LP Surviving Entity”). Following the Initial LP Merger, (a) GP Merger Sub will merge with and into Compressco GP (the “GP Merger”), with Compressco GP surviving the GP Merger as a direct, wholly-owned subsidiary of Kodiak Services and (b) Unit Merger Sub will merge with and into the Initial LP Surviving Entity (the “Subsequent LP Merger” and, together with the Initial LP Merger, the “LP

Mergers” and, together with the GP Merger, the “Mergers”), with the Initial LP Surviving Entity surviving the Subsequent LP Merger as a wholly owned subsidiary of Kodiak Services. On December 18, 2023, the board of directors of Compressco GP unanimously approved the Merger Agreement and the transactions contemplated thereby. On December 18, 2023, the board of directors of Kodiak unanimously approved the Merger Agreement and the transactions contemplated thereby.

As a result of the Mergers, Kodiak will acquire 100% of the Issuer’s outstanding equity interests. The Reporting Persons will receive, in consideration of each (i) common unit representing limited partnership interests in the Issuer (“Common Units”) and (ii) notional unit representing the general partner interest in the Issuer, 0.086 (the “Exchange Ratio”) units (“OpCo Units”) in Kodiak Services and an equal number of shares of Series A Preferred Stock of Kodiak (“Series A Preferred Stock”). The other common unitholders will receive, in consideration of each Common Unit, either (i) a number of shares of common stock, par value $0.01 per share, of Kodiak (“Kodiak Common Stock”) equal to the Exchange Ratio, or (ii) for certain eligible holders, at their election, a number of OpCo Units and shares of Series A Preferred Stock equal to the Exchange Ratio. Each OpCo Unit will be redeemable for one share of Kodiak Common Stock (together with the cancellation of one share of Series A Preferred Stock) pursuant to the terms of the Sixth Amended and Restated Limited Liability Company Agreement of Kodiak Services. The Mergers are expected to be completed in the second quarter of 2024, subject to customary closing conditions, including Hart-Scott-Rodino antitrust clearance and Kodiak’s registration statement on Form S-4 (the “Form S-4”) having been declared effective by the U.S. Securities and Exchange Commission (“SEC”) under the Act.

Support and Lockup Agreements

As an inducement to Kodiak entering into the Merger Agreement, on December 19, 2023, each of Spartan LP, Merced Capital LP, Orvieto Partners, L.P. and the named executive officers of Compressco GP (the “Supporting Unitholders”), beneficially owning 78,016,332 Common Units in the aggregate, entered into separate Support and Lockup Agreements with Kodiak, Compressco GP and the Issuer (the “Support Agreements” and the Support Agreement between CSI Investment, Spartan LP, Kodiak, Compressco GP and the Issuer, the “Spartan Support Agreement”). Pursuant to the Support Agreements, the Supporting Unitholders agreed to, among other things, promptly following the time when the Form S-4 has been declared effective by the SEC and the Supporting Unitholders have received from Kodiak a copy of the consent statement/prospectus included therein, execute and deliver a written consent covering all of such Supporting Unitholder’s Common Units approving each of the matters for which the Issuer is soliciting consents of the holders of Common Units in accordance with the Merger Agreement pursuant to the consent statement/prospectus. The Supporting Unitholders have also agreed to not transfer the Kodiak Common Stock received in connection with the Mergers for 180 days from the closing of the Merger.

The foregoing summary of the Spartan Support Agreement is not complete and is qualified in its entirety by reference to the full text of the Spartan Support Agreement, a copy of which is attached as Exhibit 7 to this Schedule 13D and incorporated herein by reference. It is not intended to provide any other factual information about the parties or their respective subsidiaries and affiliates. The Spartan Support Agreement contains representations and warranties by each of the parties to the Spartan Support Agreement, which were made only for purposes of the Spartan Support Agreement and as of a specified date. The representations, warranties and covenants in the Spartan Support Agreement were made solely for the benefit of the parties to the Spartan Support Agreement, may be subject to limitations agreed upon by the contracting parties, and may be subject to standards of materiality, applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Spartan Support Agreement, which subsequent information may or may not be fully reflected in the Issuer’s public disclosures.
