Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments We entered into certain commitments for fixed assets, consumables and services incidental to the ordinary conduct of our business, generally for quantities required for our operations and at competitive market prices. These commitments are designed to assure sources of supply and are not expected to be in excess of normal requirements. We entered into contractual arrangements with an equipment manufacturer to purchase mobile natural gas-fueled power generation equipment, including turbine generator sets along with auxiliary equipment, for our PROPWR® business line, with a total remaining commitment (after our initial down payment and payments financed under the Caterpillar Equipment Loan Agreement) of approximately $13.3 million, none of which will be financed under the Caterpillar Equipment Loan Agreement. Under the Caterpillar Equipment Loan Agreement, we have incurred interim loans and term loans with outstanding amounts of $0 and $171.8 million, respectively, as of September 30, 2026, related to funding for equipment under construction and equipment received. See "Note 5 - Interim and Long-Term Debt." We expect to receive the remaining equipment currently on order under these arrangements in the second quarter of fiscal year 2027. On April 28, 2026, ProPetro Energy Solutions, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("PROPWR"), entered into a global framework agreement with Caterpillar Inc., a Delaware corporation ("Caterpillar"), under which PROPWR agreed to purchase approximately 1.5 gigawatts of incremental power generation assets, subject to certain termination rights of PROPWR and Caterpillar (the "Framework Agreement"). Under the Framework Agreement, we had a minimum purchase obligation at signing of approximately $1,106.0 million subject to adjustments including annual escalations, taxes and tariffs, not inclusive of balance of plant, as well as the option to acquire up to an additional approximately 600 megawatts over a period of approximately five years ending December 31, 2031. As of September 30, 2026, we had approximately 570 megawatts of equipment on order under this Framework Agreement with a remaining commitment of approximately $463.1 million. We expect to receive this equipment from the fourth quarter of fiscal year 2026 through late fiscal year 2028. We also entered into contractual arrangements with other equipment manufacturers to purchase additional power generation and auxiliary equipment for our PROPWR® business line, with a total remaining commitment of approximately $169.8 million. We expect to receive the remaining equipment currently on order under these arrangements from the fourth quarter of fiscal year 2026 through the end of fiscal year 2027. On May 7, 2026, the Company issued $690.0 million aggregate principal amount of Convertible Notes, which included the exercise in full of the initial purchasers’ option to purchase up to an additional $90.0 million principal amount of the Convertible Notes, the proceeds of which (after debt issuance costs, discounts and approximately $36.8 million for capped call transactions related to the Convertible Notes) are intended to be used to purchase additional power generation equipment among other general corporate purposes. The total remaining contractual commitment in connection with the Electric Fleet Leases excluding the cost associated with the option to purchase the equipment at the end of each lease is approximately $43.0 million. The total estimated contractual commitment in connection with the Power Equipment Lease is approximately $1.7 million. We also have leases for facilities and office spaces with a total estimated contractual commitment of approximately $10.0 million. See "Note 11- Leases" for further details on these leases. The Company enters into purchase agreements with its sand suppliers (the "Sand Suppliers") to secure supply of sand as part of its normal course of business. The agreements with the Sand Suppliers require that the Company purchase a minimum volume of sand, based primarily on predetermined fixed minimum volumes, otherwise certain shortfall fees will be charged. The shortfall fee represents prepayments and potential liquidated damages and is a fixed price per ton of unpurchased volumes. Any shortfall fees paid will be first credited towards certain future sand purchases and any remaining unutilized amounts will be considered liquidated damages. Our existing agreements with the Sand Suppliers expire at different times on or before May 31, 2029. Our agreements with two Sand Suppliers that will expire on July 1, 2027, have a take-or-pay commitment of approximately $1.3 million as of September 30, 2026. During the nine months ended September 30, 2026 and 2025, no shortfall fees representing liquidated damages were recorded. The Stonebriar Equipment Lease Facility requires us to pay an unused commitment fee of 0.5% of any unused portion of the lessor’s $350.0 million funding commitment at December 31, 2028. The maximum amount we may owe for this fee is $1.8 million. As of September 30, 2026 and December 31, 2025, the Company had issued letters of credit of approximately $11.1 million and $8.6 million, respectively, under the ABL Credit Facility in connection with the Company’s casualty insurance policy. Such letters of credit reduce the amount available to borrow under the ABL Credit Facility. Contingent Liabilities Legal Matters We have been named in various claims, lawsuits or threatened actions in the ordinary course of our business. We intend to defend these matters vigorously; however, litigation is inherently unpredictable, and the ultimate outcome or effect of any claim, lawsuit or action cannot be predicted with certainty. As a result, there can be no assurance as to the ultimate outcome of any litigation matter. Any claims against us, whether meritorious or not, could cause us to incur significant costs and expenses and require significant amounts of management and operational time and resources. With respect to each matter or exposure, we have made an assessment, in accordance with GAAP, of the probability that the resolution of the matter would ultimately result in a loss. When we determine that an unfavorable resolution of a matter is probable and such amount of loss can be estimated, we record a liability at the time that both of these criteria are met. Our management believes that we have recorded adequate accruals for any liabilities that may reasonably be expected to result from these matters. In the opinion of our management, no pending or known threatened claims, actions or proceedings against us are expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. Environmental and Insurance Matters The Company is subject to various federal, state and local environmental laws and regulations that establish standards and requirements for protection of the environment. The Company cannot predict the future impact of such standards and requirements, which are subject to change and can have retroactive effectiveness. The Company continues to monitor the status of these laws and regulations. Currently, the Company has not been fined, cited or notified of any environmental violations that would have a material adverse effect upon its financial position, liquidity or capital resources. However, management does recognize that by the very nature of the Company's business, material costs could be incurred in the near term to maintain compliance. The amount of such future expenditures is not determinable due to several factors, including the unknown magnitude of possible regulation or liabilities, the unknown timing and extent of the corrective actions which may be required, the determination of the Company's liability in proportion to other responsible parties and the extent to which such expenditures are recoverable from insurance or indemnification. The Company is self-insured up to $10 million per occurrence for certain losses. No accrual was recorded in our financial statements in connection with this self-insurance strategy because the occurrence of events that would give rise to a self-insured liability cannot be reasonably estimated. Regulatory Audits In 2020, the Texas Comptroller of Public Accounts (the "Comptroller") commenced a routine audit of the Company's motor vehicle and other related fuel taxes for the periods of July 2015 through December 2020. In January 2024, the Company received the audit findings and subsequently filed a request for redetermination with the Comptroller, which remains under review. Based on the current status of the matter, the Company expects to resolve the audit through a settlement of approximately $6.0 million. As of September 30, 2026, the Company has remitted $4.5 million to the Comptroller and has accrued the remaining $1.5 million, which represents management's best estimate of the remaining obligation. In May 2022, the Company received a notification from the Comptroller that it will commence a routine audit of the Company's gross receipt taxes, which will routinely cover up to a four-year period. The audit concluded in August 2026 and resulted in a refund of $0.2 million. In February 2026, the Company received a notification from the Comptroller that it will commence a routine audit of the Company's direct payment sales tax relating specifically to the Company's wholly owned subsidiary Silvertip Completion Services Operating, LLC, for a period of up to four years. As of September 30, 2026, the audit was ongoing and its final outcome cannot be reasonably estimated. In May 2026, the Texas Workforce Commission commenced a routine audit of the Company's compliance with the Texas Unemployment Compensation Act for the period January 1, 2024 through December 31, 2024. The audit concluded in September 2026 and resulted in no liability. In July 2026, the Company and certain of its subsidiaries were accepted into the State of Delaware’s Abandoned or Unclaimed Property Voluntary Disclosure Agreement Program. Under the program, the Company is reviewing its books and records for property that may be presumed abandoned or unclaimed for the period from January 1, 2011 through the present and will report and remit any amounts determined to be due. As of September 30, 2026, the Company’s review was ongoing, and the amount of liability, if any, cannot be reasonably estimated. In August 2026, the Company received a notification from the Comptroller that it will commence a routine audit of the Company's direct payment sales tax relating specifically to the Company's wholly owned subsidiary ProPetro Services, Inc., for a period of up to four years. As of September 30, 2026, the audit was ongoing and its final outcome cannot be reasonably estimated.
