**Item 4.01 Changes in Registrant's Certifying Accountant.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(a) Dismissal of Independent Registered Public Accounting Firm.***

On February 24, 2023, the Audit Committee of the Board of Directors (the "Audit Committee") of ProPetro Holding Corp. (the "Company") dismissed Deloitte & Touche LLP ("Deloitte") as the Company's independent registered public accounting firm.

During the Company's two most recent fiscal years ended December 31, 2022 and December 31, 2021 and during the subsequent interim period from January 1, 2023 through February 24, 2023, (i) there were no disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures that, if not resolved to Deloitte's satisfaction, would have caused Deloitte to make reference to the subject matter of the disagreement in connection with its reports and (ii) there were no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K.

The audit reports of Deloitte on the consolidated financial statements of the Company for each of the two most recent fiscal years ended December 31, 2022 and December 31, 2021 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

In accordance with Item 304(a)(3) of Regulation S-K, the Company provided Deloitte with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission ("SEC") and requested that Deloitte furnish it with a letter addressed to the SEC stating whether it agrees with the above statements in this Item 4.01(a). A copy of Deloitte's letter, dated March 1, 2023, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(b) Appointment of New Independent Registered Public Accounting Firm.***

On February 24, 2023, the Audit Committee approved the engagement of RSM US LLP ("RSM") as its new independent registered public accounting firm. RSM's appointment will be for the Company's fiscal year ending December 31, 2023, and related interim periods.

During the Company's two most recent fiscal years ended December 31, 2022 and December 31, 2021, and for the subsequent interim period through February 24, 2023, neither the Company nor anyone on its behalf consulted RSM regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the consolidated financial statements of the Company, in connection with which neither a written report nor oral advice was provided to the Company that RSM concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement as defined in Item 304(a)(1)(iv) of Regulation S-K or a reportable event as described in Item 304(a)(1)(v) of Regulation S-K.
