| Amendment Description | On March 2, 2022, Exterran Corporation (“Exterran”) filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the “Original Form 10-K”). Exterran is filing this Amendment No. 1 on Form 10-K/A (the “Form 10-K/A) in order to include the information required by Part III, Items 10 through 14 for Form 10-K. This information was previously omitted from the Original Form 10-K consistent with General Instruction G(3) to Form 10-K. Exterran is filing this amendment because we do not intend to file our definitive proxy statement within 120 days of the end of our fiscal year ended December 31, 2021. In connection with the filing of the Form 10-K/A and pursuant to the rules of the SEC, we are including with the Form 10-K/A new certifications by our principle executive and principal financial officers. Accordingly, Item 15 of Part IV has also been amended to reflect the filing of these new certifications. Except as described above, no other changes have been made to the Original Form 10-K. The Original Form 10-K continues to speak as of the date of the Original Form 10-K, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Form 10-K other than expressly indicated in this Form 10-K/A. In this Form 10-K/A , unless the context indicates otherwise, the terms “Company,” “our,” “we” or “us” refer to Exterran. Other defined terms used in this Form 10-K/A but not defined herein shall have the meaning specified for such terms in the Original Form 10-K. All statements in this Form 10-K/A that are not historical are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements can generally be identified as such because the context of the statement will include words such as “may,” “will,” “intend,” “plans,” “believes,” “anticipates,” “expects,” “estimates,” “predicts,” “potential,” “continue,” “opportunity,” “goals,” or “should,” the negative of these words or words of similar import. Similarly, statements that describe our future plans, strategies, intentions, expectations, objectives, goals or prospects are also forward-looking statements. These forward-looking statements are or will be, as applicable, based largely on our expectations and projections about future events and future trends affecting our business, and so are or will be, as applicable, subject to risks and uncertainties including but not limited to the risk factors discussed in the Original Form 10-K, that could cause actual results to differ materially from those anticipated in the forward-looking statements. We caution investors that there can be no assurance that actual results or business conditions will not differ materially from those projected or suggested in such forward-looking statements. Our views and the events, conditions and circumstances on which these future forward-looking statements are based, may change. | ||
