Amendment Description	This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “Original Report”), which was filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2026 (the “Original Filing Date”). The purpose of this Amendment is to provide the information required by Items 10 through 14 of Part III of Form 10-K, which was previously omitted from the Original Report in reliance on General Instruction G(3) to Form 10-K.This Amendment also amends Item 15 of Part IV of the Original Report to include as exhibits the new certifications required by Rule 13a-14(a) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements are included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Item 307 or 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 because no financial statements are included in this Amendment.Except as described above, no other changes have been made to the Original Report. The Original Report continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events that occurred at a date subsequent to the Original Filing Date other than as expressly indicated in this Amendment. Accordingly, this Amendment should be read in conjunction with the Original Report and our other filings with the SEC subsequent to the filing of the Original Report.As used herein, the terms “Company,” “Nine,” “we,” “us” and “our” refer to Nine Energy Service, Inc., either individually or together with its subsidiaries, as the context requires.
