To the Shareholders and the Board of Directors of ProPetro Holding Corp.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ProPetro Holding Corp and its subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 19, 2026 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Accounting for Power Generation Arrangements

As disclosed in Note 2 to the financial statements, the Company’s power generation arrangements involve providing turnkey power generation services to customers using mobile power generation equipment installed at customers’ sites. The evaluation of the accounting implications of these power generation arrangements requires the application of complex accounting rules and consideration of several factors which can impact the amount and timing of revenue recognized. The Company evaluates whether the use of its power generation equipment installed at customers’ sites to provide power generation services represents a lease in accordance with the applicable accounting guidance. If a lease is identified, the accounting guidance requires management to assess whether the lease component is separate from the nonlease components, determine the appropriate allocation of consideration based on relative standalone selling prices, and evaluate the resulting revenue recognition and lease classification implications. For the power generation arrangements entered into during the year ended December 31, 2025, management determined that an operating lease existed in the contract and the nonlease components, primarily power generation and related support activities, represent the predominant components of the contract; accordingly the Company has accounted for the lease and nonlease components as a single performance obligation and recognizes the revenue over time as the Company delivers the services.

We identified the Company’s evaluation of the accounting treatment of the power generation arrangements as a critical audit matter because of the complexity involved in management’s evaluation of the contracts, including management’s interpretation and application of the applicable accounting rules and the judgments required by management to analyze the nature of the services provided, assess whether the embedded lease conveyed the right to control the use of an identified asset, and to estimate standalone selling prices for the nonlease components. Auditing management’s accounting conclusions involved a high degree of auditor judgment and an increase in audit effort due to the impact management’s conclusions could have on the Company’s accounting for the power generation arrangements.

Our audit procedures related to the Company’s evaluation of the accounting treatment of the power generation arrangements included the following, among others:

•We obtained an understanding of the relevant controls related to management’s evaluation of the power generation arrangements and tested such controls for design and operating effectiveness.

•We obtained management’s technical accounting memorandum and evaluated the reasonableness of management’s conclusions on the accounting treatment of the power generation arrangements by assessing whether the Company’s conclusions regarding the identification of a lease, the classification of the lease, and revenue recognition principles were consistent with relevant accounting guidance.

•We sampled the Company’s power generation arrangements and read the customer agreements to assess the existence of identified assets and whether control of those assets was conveyed to the customer.

•We tested management’s allocation of consideration between lease and nonlease components in its power generation arrangements, which management based on standalone selling prices, by comparing the inputs in management’s allocation to applicable contract terms and available market data and testing the mathematical accuracy of management's calculations.

Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.

Definition and Limitations of Internal Control Over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
