Item 1.01. Entry Into a Material Definitive Agreement.

As previously disclosed, on January 1, 2018, Archrock, Inc., a Delaware corporation (“Archrock”), Archrock Partners, L.P., a Delaware limited partnership (the “Partnership”), Archrock General Partner, L.P., a Delaware limited partnership and the general partner of the Partnership (the “General Partner”), and Archrock GP LLC, a Delaware limited liability company and the general partner of the General Partner (the “Managing GP”), entered into an Agreement and Plan of Merger (the “Original Agreement”), pursuant to which a wholly owned subsidiary of Archrock will merge with and into the Partnership, with the Partnership surviving as an indirect wholly owned subsidiary of Archrock (the “Merger”).

The Original Agreement provided that Archrock (through one or more intermediate entities) would form a new wholly owned subsidiary solely for the purpose of engaging in the transactions contemplated by the Original Agreement, including merging with and into the Partnership to effect the merger at the effective time thereof, and that the Original Agreement would be amended to join such new subsidiary as a party thereto.

On January 11, 2018, following the formation of Amethyst Merger Sub LLC as an indirect wholly owned subsidiary of Archrock (“Merger Sub”), Archrock and Merger Sub entered into Amendment No. 1 to Agreement and Plan of Merger (the “Amendment” and the Original Agreement as amended by the Amendment, the “Merger Agreement”) with the Partnership, the General Partner and the Managing GP solely for the purpose of joining Merger Sub as a party thereto.

The Original Agreement and the Amendment are included as Exhibits 2.1 and 2.2 hereto, respectively, and are incorporated by reference. The foregoing summary has been included to provide investors and security holders with information regarding the terms of the Merger Agreement and is qualified in its entirety by the terms and conditions of the Merger Agreement. It is not intended to provide any other factual information about Archrock, the Partnership or their respective subsidiaries and affiliates. The Merger Agreement contains representations and warranties by each of the parties to the Merger Agreement, which were made only for purposes of the Merger Agreement and as of specified dates. The representations, warranties and covenants in the Merger Agreement were made solely for the benefit of the parties to the Merger Agreement; may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts; 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 Archrock, the Partnership 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 Merger Agreement, which subsequent information may or may not be fully reflected in Archrock’s or the Partnership’s public disclosures.

Forward-Looking Statements

All statements in this report (and oral statements made regarding the subjects of this communication) other than historical facts are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements rely on a number of assumptions concerning future events and are subject to a number of uncertainties and factors, many of which are outside the control of Archrock and the Partnership, which could cause actual results to differ materially from such statements.  Forward-looking information includes, but is not limited to: statements regarding the expected benefits of the proposed transaction to the Partnership and its unitholders; the anticipated completion of the proposed transaction and the timing thereof; the expected future growth, dividends and distributions of the combined company; and plans and objectives of management for future operations.  While Archrock believes that the assumptions concerning future events are reasonable, it cautions that there are inherent difficulties in predicting certain important factors that could impact the future performance or results of its business. Among the factors that could cause results to differ materially from those indicated by such forward-looking statements are: the failure to realize the anticipated costs savings, synergies and other benefits of the transaction; the possible diversion of management time on transaction-related issues; the risk that the requisite approvals to complete the transaction are not obtained; local, regional and national economic conditions and the impact they may have on Archrock, the Partnership and their customers; changes in tax laws that impact master limited partnerships; conditions in the oil and gas industry, including a sustained decrease in the level of supply or demand for oil or natural gas or a sustained decrease in the price of oil or natural gas; the financial condition of Archrock’s and the Partnership’s customers; any non-performance by customers of their contractual obligations; changes in customer, employee or supplier relationships resulting from the transaction; changes in safety, health, environmental and other regulations; the results of any reviews, investigations or other proceedings by government authorities; the results of any shareholder actions that may be filed relating to the restatement of Archrock’s financial statements; the potential additional costs relating to Archrock’s restatement, cost-sharing with Exterran Corporation and to addressing any reviews, investigations or other proceedings by government authorities or shareholder actions; and the performance of the Partnership.

These forward-looking statements are also affected by the risk factors, forward-looking statements and challenges and uncertainties described in each of Archrock’s and the Partnership’s Annual Reports on Form 10-K for the year ended December 31, 2016, and those set forth from time to time in each party’s filings with the SEC, which are available at www.archrock.com. Except as required by law, Archrock and the Partnership expressly disclaim any intention or obligation to revise or update any forward-looking statements whether as a result of new information, future events or otherwise.
