NINE · Nine Energy Service, Inc.

Nine Energy Service, Inc. filed this Current Report on Form 8-K to disclose the submission of its final Monthly Operating Report (MOR) to the Bankruptcy Court. The Company and its subsidiaries filed voluntary Chapter 11 petitions on February 1, 2026, and successfully emerged from bankruptcy on March 5, 2026, following the confirmation of the prepackaged plan of reorganization on March 4, 2026. Consequently, this MOR covers only the brief four-day period from March 1, 2026, through March 4, 2026.

The financial results for this period reflect the unique circumstances of the bankruptcy proceedings. The Company reported a net loss of approximately $13.9 million, primarily driven by $13.4 million in reorganization items. Operating activity was minimal, with zero gross income/sales reported for the specific reporting period. The balance sheet as of March 4, 2026, shows total assets of $36.6 million against total liabilities of $429.4 million, resulting in a significant negative equity position of approximately $393 million. The liability total includes $319.5 million in prepetition secured debt. Cash flow remained positive during the period, with the cash balance increasing to $23.4 million from $21.1 million at the beginning of the month, aided by total receipts of $5.4 million against disbursements of $3.1 million.

The Company explicitly cautioned investors that the MOR was prepared solely for compliance with Bankruptcy Code requirements and is not in accordance with U.S. GAAP. The report covers a shortened period and may not be indicative of the Company's financial condition post-emergence. The Company emerged from bankruptcy the day following the reporting period end date.
