Bankruptcy Proceedings and Emergence from Bankruptcy On February 1, 2026 (the “Petition Date”), the Company and its domestic and Canadian subsidiaries (collectively with the Company, the “Company Parties”) filed voluntary petitions (the “Chapter 11 Cases”), Case No. 26-90295, under chapter 11 (“Chapter 11”) of title 11 of the United States Bankruptcy Code, 11 U.S.C. §§ 101–1532, as amended (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) to implement a prepackaged Chapter 11 plan of reorganization (the “Plan”) to effectuate a financial restructuring for the Company Parties’ existing indebtedness in accordance with the Restructuring Support Agreement (as defined below). Prior to filing the Chapter 11 Cases, on February 1, 2026, the Company Parties entered into a restructuring support agreement (the “Restructuring Support Agreement”) with an ad hoc group (collectively, the “Consenting Stakeholders”) of certain holders of the Company’s 13.000% Senior Secured Notes due 2028 (the “2028 Notes”) and the lenders (the “Prepetition ABL Lenders”) under the Loan and Security Agreement, dated as of May 1, 2025 (the “Prepetition ABL Loan and Security Agreement”), by and among the Company and certain subsidiaries thereof, each as a borrower or guarantor, as applicable, White Oak Commercial Finance, LLC, as agent for the lenders, and the lenders from time to time party thereto. Pursuant to the Restructuring Support Agreement, the Consenting Stakeholders agreed, subject to certain terms and conditions, to support the Plan. On March 4, 2026, the Bankruptcy Court entered an order confirming the Plan, and on March 5, 2026 (the “Plan Effective Date”), the Plan became effective in accordance with its terms and the Company Parties emerged from bankruptcy. The material terms of the Plan included, among other things: •the Prepetition ABL Lenders providing the Company Parties with a senior secured super-priority asset-based debtor-in-possession credit facility consisting of up to $125.0 million in aggregate principal amount of revolving credit commitments, including a roll-up or refinancing of all obligations under the Prepetition ABL Loan and Security Agreement, which converted into an exit senior secured asset-based revolving credit facility consisting of $135.0 million in aggregate principal amount of revolving commitments on the Plan Effective Date; •on the Plan Effective Date, the reorganized Company issuing 100% of a single class of common equity interests (consisting of 13,949,990 shares of new common stock) to the holders of the 2028 Notes and the 2028 Notes were canceled; and •on the Plan Effective Date, all of the Company’s equity interests outstanding prior to the Plan Effective Date, including common stock, were canceled for no consideration. Upon the Plan Effective Date, the Company applied fresh start accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 852-Reorganizations (“ASC 852”). The application of fresh start accounting resulted in a new basis of accounting and the Company becoming a new entity for financial reporting purposes. Accordingly, the Company’s financial statements and notes after the Plan Effective Date are not comparable to its financial statements and notes on and prior to that date. This delineation between periods ending on or prior to the Plan Effective Date and periods after the Plan Effective Date is shown in the unaudited condensed consolidated financial statements, certain tables within these notes, and other parts of this Quarterly Report on Form 10-Q through the use of a black line that emphasizes the lack of comparability between periods. For additional information, see Note 3 – Emergence from Bankruptcy. In this Quarterly Report on Form 10-Q, the “Successor” refers to the Company after its emergence from bankruptcy and the “Predecessor” refers to the Company prior to its emergence from bankruptcy, and references to the financial position and results of operations of the Successor are to the financial position and results of operations of the Company after the Plan Effective Date and references to the financial position and results of operations of the Predecessor are to the financial position and results of operations of the Company on and prior to the Plan Effective Date. Also, in this Quarterly Report on Form 10-Q, the period from March 6, 2026 through March 31, 2026 is referred to as the “2026 Successor Period,” the period from January 1, 2026 through March 5, 2026 is referred to as the “2026 Predecessor Period” and the three months ended March 31, 2025 is referred to as the “2025 Predecessor Period.” Other Risks and Uncertainties As Nine is a spot-market business, the Company’s business and its pricing depends, to a significant extent, on the level of unconventional resource development activity and corresponding capital spending of oil and natural gas companies. These activity and spending levels are strongly influenced by current and expected oil and natural gas prices, which have been extremely volatile historically and in recent years. In addition, the Company’s earnings are affected by its ability to maintain current pricing levels, the impact of wage and labor inflation, labor shortages, and supply chain constraints. Due to the spot-market nature of its business, the Company’s revenue and earnings generally move very similarly to rig, frac, and stage counts in U.S. rig count.

Other Risks and Uncertainties

As Nine is a spot-market business, the Company’s business and its pricing depends, to a significant extent, on the level of unconventional resource development activity and corresponding capital spending of oil and natural gas companies. These activity and spending levels are strongly influenced by current and expected oil and natural gas prices, which have been extremely volatile historically and in recent years. In addition, the Company’s earnings are affected by its ability to maintain current pricing levels, the impact of wage and labor inflation, labor shortages, and supply chain constraints. Due to the spot-market nature of its business, the Company’s revenue and earnings generally move very similarly to rig, frac, and stage counts in U.S. rig count.
