ProPetro Holding Corp. 10-K

Item 8. Financial Statements and Supplementary Data. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and the Board of Directors of ProPetro Holding Corp. and Subsidiary Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of ProPetro Holding Corp. and Subsidiary (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of operations, shareholders' equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively, referred to as, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2022, expressed an unqualified opinion on 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 the 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 Matter 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 critical audit matters 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. Related-party transactions — Refer to Note 13 to the consolidated financial statements Critical Audit Matter Description The Company engages in various related party transactions, including leasing real estate, renting equipment, purchasing assets, obtaining equipment maintenance and repair services, and providing pressure pumping and related services. We identified related-party transactions as a critical audit matter because of the number of related-party transactions and potential conflicts of interest. As a result, we believe the risk that related-party transactions were not timely identified and properly disclosed by the Company in the financial statements was elevated and required us to 49 exercise significant auditor judgment and an increased extent of effort when designing and performing audit procedures on related-party transactions. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures for related-party transactions included the following, among others: • We evaluated the completeness of related-party transactions by obtaining the Company’s list of related-party relationships and transactions and performing the following: ◦ Comparing it to public filings, external news, third-party information or research reports, questionnaires completed by the Company’s directors and officers, and other sources. ◦ Searching for potential related-party transactions within the accounts receivable, accounts payable, and vendor listings master files and journal entries by searching for the name, vendor identification numbers, and customer identification numbers of the related parties. ◦ Inspecting the Company’s minutes from meetings of the Board of Directors and related committees. ◦ Making inquiries of executive officers, key members of management, and the Audit Committee of the Board of Directors regarding related party transactions. /s/ DELOITTE & TOUCHE LLP Houston, Texas February 25, 2022 We have served as the Company's auditor since 2013. 50 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and the Board of Directors of ProPetro Holding Corp. and Subsidiary Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of ProPetro Holding Corp. and Subsidiary (the "Company" ) as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021, of the Company and our report dated February 25, 2022 , expressed an unqualified opinion on those consolidated financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting . 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 the US 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, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 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. /s/ DELOITTE & TOUCHE LLP Houston, Texas February 25, 2022 51 PROPETRO HOLDING CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. ORGANIZATION AND HISTORY ProPetro Holding Corp. ("Holding"), a Texas corporation was formed on April 14, 2007, to serve as a holding company for its wholly owned subsidiary ProPetro Services, Inc. ("Services"), a Texas corporation. Services offers hydraulic fracturing, cementing and coiled tubing services to oil and gas producers, located primarily in Texas, New Mexico and Utah. Holding was converted and incorporated to a Delaware Corporation on March 8, 2017. Unless otherwise indicated, references in these notes to consolidated financial statements to "ProPetro Holding Corp.," "the Company," "we," "our," "us" or like terms refer to ProPetro Holding Corp. and Services. On December 31, 2018, we consummated the purchase of pressure pumping and related assets of Pioneer Natural Resources USA, Inc. ("Pioneer") and Pioneer Pumping Services, LLC (the "Pioneer Pressure Pumping Acquisition"). The pressure pumping assets acquired were used to provide integrated well completion services in the Permian Basin to Pioneer’s completion and production operations. The acquisition cost of the assets was comprised of $ 110.0 million of cash and 16.6 million shares of our common stock. The pressure pumping assets acquired included hydraulic fracturing pumps of 510,000 hydraulic horsepower ("HHP"), four coiled tubing units and the associated equipment maintenance facility. In connection with the acquisition, we became a long-term service provider to Pioneer under a pressure pumping services agreement (the "Pioneer Services Agreement"), providing pressure pumping and related services for a term of up to 10 years; provided, that Pioneer has the right to terminate the Pioneer Services Agreement, in whole or in part, effective as of December 31 of each of the calendar years of 2022, 2024 and 2026. Pioneer can increase the number of committed fleets prior to December 31, 2022. Pursuant to the Pioneer Services Agreement, the Company is entitled to receive compensation if Pioneer were to idle committed fleets ("idle fees"); however, we are first required to use all economically reasonable effort to deploy the idled fleets to another customer. At the present, we have eight fleets committed to Pioneer. 2. SIGNIFICANT ACCOUNTING POLICIES A summary of the significant accounting policies consistently applied in the preparation of the accompanying consolidated financial statements are as follows: Principles of Consolidation — The accompanying consolidated financial statements include the accounts of Holding and its wholly owned subsidiary, Services. All intercompany accounts and transactions have been eliminated in consolidation. Basis of Presentation — The accompanying consolidated financial statements and related notes have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC") and in conformity with accounting principles generally accepted in the United States of America ("GAAP"). Use of Estimates — Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the reporting period. Such estimates include, but are not limited to, allowance for credit losses, useful lives for depreciation of property and equipment, estimates of fair value of property and equipment, estimates related to fair value of reporting units for purposes of assessing goodwill (if any), estimates related to deferred tax assets and liabilities, including any related valuation allowances, and estimates of fair value of stock‑based compensation. Actual results could differ from those estimates. Revenue Recognition — The Company’s services are sold based upon contracts with customers. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of the principal activities, aggregated into our one reportable segment—"Pressure Pumping" and "all other" category, from which the Company generates its revenue. Pressure Pumping — Pressure pumping consists of downhole pumping services, which includes hydraulic fracturing (inclusive of acidizing services) and cementing. Hydraulic fracturing is a well-stimulation technique intended to optimize hydrocarbon flow paths during the completion phase of shale wellbores. The process involves the injection of water, sand and chemicals under high pressure into shale formations. Our hydraulic fracturing contracts with our customers have one 56 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 2. SIGNIFICANT ACCOUNTING POLICIES (Continued) performance obligation, which is the contracted total stages, satisfied over time. We recognize revenue over time using a progress output, unit-of-work performed method, which is based on the agreed fixed transaction price and actual stages completed. We believe that recognizing revenue based on actual stages completed faithfully depicts how our hydraulic fracturing services are transferred to our customers over time. In addition, certain of our hydraulic fracturing equipment is entitled to daily idle fee charges if a customer were to idle committed hydraulic fracturing equipment. The Company recognizes revenue related to idle fee charges on a daily basis as the performance obligations are met. Acidizing, which is part of our hydraulic fracturing operating segment, involves a well-stimulation technique where acid or similar chemicals are injected under pressure into formations to form or expand fissures. Our acidizing contracts have one performance obligation, satisfied at a point-in-time, upon completion of the contracted service or sale of acid or chemical when control is transferred to the customer. Jobs for these services are typically short term in nature, with most jobs completed in less than a day. We recognize acidizing revenue at a point-in-time, upon completion of the performance obligation. Our cementing services use pressure pumping equipment to deliver a slurry of liquid cement that is pumped down a well between the casing and the borehole. Our cementing contracts have one performance obligation, satisfied at a point-in-time, upon completion of the contracted service when control is transferred to the customer. Jobs for these services are typically short term in nature, with most jobs completed in less than a day. We recognize cementing revenue at a point-in-time, upon completion of the performance obligation. The transaction price for each performance obligation for all our pressure pumping services is fixed per our contracts with our customers. All Other — All other consists of coiled tubing operations, which are downhole well completion/remedial services. The performance obligation for these services has a fixed transaction price which is satisfied at a point-in-time upon completion of the service when control is transferred to the customer. Accordingly, we recognize revenue at a point-in-time, upon completion of the service and transfer of control to the customer. Accounts Receivable — Accounts receivables are stated at the amount billed and billable to customers. At December 31, 2021 and 2020 accrued revenue (unbilled receivable) included as part of our accounts receivable was $ 19.4 million and $ 8.6 million, respectively. At December 31, 2021, the transaction price allocated to the remaining performance obligation for our partially completed hydraulic fracturing operations was $ 16.8 million, which is expected to be completed and recognized within one month following the current period balance sheet date, in our pressure pumping reportable segment. At December 31, 2020 the transaction price allocated to the remaining performance obligation for our then partially completed hydraulic fracturing operations was $ 14.7 million, which was recorded as part of our pressure pumping segment revenue for the year ended December 31, 2021. As of December 31, 2021, the Company had $ 0.2 million allowance for credit losses. Our allowance for credit losses is based on the evaluation of both our historic collection experience and economic outlook for the oil and gas industry. We evaluated the historic loss experience on our accounts receivable and also considered separately customers with receivable balances that may be negatively impacted by current or future economic developments and market conditions. While the Company has not experienced significant credit losses in the past and has not yet seen material changes to the payment patterns of its customers, the Company cannot predict with any certainty the degree to which the impacts of the COVID-19 pandemic, including the potential impact of periodically adjusted borrowing base limits, level of hedged production, or unforeseen well shut-downs may affect the ability of its customers to timely pay receivables when due. Accordingly, in future periods, the Company may revise its estimates of expected credit losses. 57 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 2. SIGNIFICANT ACCOUNTING POLICIES (Continued) The table below shows a summary of allowance for credit losses during the year ended December 31, 2021: ($ in thousands) 2021 2020 2019 Balance - January 1, 2021 $ 1,497 $ 1,049 $ 100 Provision for credit losses during the period—net 282 448 949 Write-off during the period ( 1,562 ) — — Balance - December 31, 2021 $ 217 $ 1,497 $ 1,049 Inventories — Inventories, which consists only of raw materials, are stated at lower of average cost and net realizable value. Property and Equipment — The Company’s property and equipment are recorded at cost, less accumulated depreciation. Depreciation — Depreciation of property and equipment is provided on the straight‑line method over the following estimated useful lives: Land Indefinite Buildings and property improvements 5 - 30 years Vehicles 1 ‑ 5 years Equipment 1 ‑ 20 years Leasehold improvements 5 ‑ 20 years Upon sale or retirement of property and equipment, including certain major components of our pressure pumping equipment that are replaced, the cost and related accumulated depreciation are removed from the balance sheet and the net amount, less proceeds from disposal, is recognized as a gain or loss in the statement of operations. A significant portion of our loss on disposal of assets relates to replacement of major components like fluid and power ends. The Company recorded a loss on disposal of assets of $ 64.6 million , $ 58.1 million and $ 106.8 million for the years ended December 31, 2021, 2020 and 2019, respectively. Impairment of Long‑Lived Assets — In accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 360, Accounting for the Impairment or Disposal of Long‑Lived Assets , the Company reviews its long‑lived assets to be held and used whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future undiscounted cash flows attributable to the asset group is less than the carrying amount of such asset group. In this circumstance, the Company recognizes an impairment loss for the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. No impairment expense was recorded during the year ended December 31, 2021. Property and equipment impairment loss of $ 27.5 million and $ 1.1 million was recorded during the year ended December 31, 2020 relating to our pressure pumping and drilling assets, respectively. Property and equipment impairment loss of $ 1.2 million and $ 2.2 million was recorded during the year ended December 31, 2019 relating to our drilling and flowback asset groups, respectively. Our drilling and flowback asset groups are included in the “all other” category in our reportable segment disclosure. The Company accounts for long‑lived assets to be disposed of at the lower of their carrying amount or fair value, less cost to sell once management has committed to a plan to dispose of the assets. Goodwill — Goodwill is the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets and liabilities recognized. Goodwill is not amortized. We perform an annual impairment test of goodwill as of December 31, or more frequently if circumstances indicate that impairment may exist. The determination of impairment is made by comparing the carrying amount of a reporting unit with its fair value, which is generally calculated using a combination of market and income approaches. If the fair value of the reporting unit exceeds the carrying value, no further testing is performed. If the fair value of the reporting unit is less 58 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 2. SIGNIFICANT ACCOUNTING POLICIES (Continued) than the carrying value, we consider goodwill to be impaired, and the amount of impairment loss is estimated and recorded in the statement of operations. In 2011, we acquired Technology Stimulation Services, LLC ("TSS") for $ 24.4 million. The assets acquired from TSS were recorded as $ 15.0 million of equipment with the excess of the purchase price over fair value of the assets recorded as goodwill of $ 9.4 million. The acquisition complemented our existing pressure pumping business. The transaction was accounted for using the acquisition method of accounting and, accordingly, assets and liabilities assumed were recorded at their fair values as of the acquisition date. There were no additions to goodwill during the y ear ended December 31, 2021. In the first quarter of 2020, we performed an interim impairment test and concluded that goodwill was fully impaired. As a result of our interim impairment test during the first quarter of 2020, we recorded goodwill impairment expense of $ 9.4 million during the year ended December 31, 2020, which fully wrote off our goodwill carrying value. There were no good will impairments during the year ended December 31, 2019. Intangible Assets — Intangible assets with finite useful lives are amortized on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized, which is generally on a straight‑line basis over the asset’s estimated useful life. Income Taxes — Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of differences between the consolidated financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, and the results of recent operations. If we determine that we would not be able to fully realize our deferred tax assets in the future, we would record a valuation allowance. Advertising Expense — All advertising costs are expensed as incurred. For the years ended December 31, 2021, 2020 and 2019, advertising expense was $ 0.8 million , $ 0.4 million and $ 1.2 million, respectively. Deferred Loan Costs — The Company capitalized certain costs in connection with obtaining its borrowings, including lender, legal, and accounting fees. These costs are being amortized over the term of the related loan using the straight‑line method. Unamortized deferred loan costs associated with loans paid off or refinanced with different lenders are expensed in the period in which such an event occurs. Deferred loan costs are classified as a reduction of long‑term debt or in certain instances as an asset in the consolidated balance sheet. Amortization of deferred loan costs is recorded as interest expense in the statement of operations, and during the years ended December 31, 2021, 2020 and 2019, the amount of expense recorded was $ 0.5 million, $ 0.5 million and $ 0.5 million, respectively. Stock-Based Compensation — The Company recognizes the cost of stock‑based awards on a straight‑line basis over the requisite service period of the award, which is usually the vesting period under the fair value method. Total compensation cost is measured on the grant date using fair value estimates. Insurance Financing — The Company annually renews its commercial insurance policies, and may choose to either directly pay the insurance premium or finance a portion of the premium. If the Company finances a portion of the premium, a prepaid insurance asset is recorded and amortized monthly over the relevant period. Concentration of Credit Risk — The Company’s assets that are potentially subject to concentrations of credit risk are cash and cash equivalents and trade accounts receivable.

SIGNIFICANT ACCOUNTING POLICIES (Continued) Recently Issued Accounting Standards Adopted in 2021 In December 2019, the FASB Accounting Standards Update ("ASU") issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 in Generally Accepted Accounting Principles. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. Effective January 1, 2021, we adopted this guidance and the adoption did not materially affect the Company’s condensed consolidated financial statements. Recently Issued Accounting Standards Not Yet Adopted in 2021 In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform , which provides temporary optional guidance to companies impacted by the transition away from the London Interbank Offered Rate ("LIBOR"). The guidance provides certain expedients and exceptions to applying GAAP in order to lessen the potential accounting burden when contracts, hedging relationships, and other transactions that reference LIBOR as a benchmark rate are modified. This guidance is effective upon issuance and expires on December 31, 2022. The Company is currently assessing the impact of the LIBOR transition and this ASU on the Company’s consolidated financial statements. 3.

FAIR VALUE MEASUREMENTS Fair value ("FV") is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit price") in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches and establishes a hierarchy for inputs used in measuring fair value that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used, when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions other market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the observability of inputs as follows: Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment. Level 2 — Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. 60 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 4. FAIR VALUE MEASUREMENTS (Continued) Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and Liabilities Measured at Fair Value on a Recurring Basis Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable, accrued and other current liabilities, and long-term debt (if any). The estimated fair value of our financial instruments at December 31, 2021 and 2020 approximated or equaled their carrying value as reflected in our consolidated balance sheets. Assets Measured at Fair Value on a Nonrecurring Basis There was no impairment of assets during the year ended December 31, 2021. During the year ended December 31, 2020, we recorded property and equipment impairment loss of approximately $ 28.6 million in connection with the depressed utilization of our pressure pumping and drilling assets . During the year ended December 31, 2019, we recorded property and equipment impairment loss of approximately $ 3.4 million in connection with our drilling and flowback assets, in our “all other” segment. We generally apply fair value techniques to our reporting units on a nonrecurring basis associated with valuing potential impairment loss related to goodwill, if any. Our estimate of the reporting unit fair value is based on a combination of income and market approaches, Level 1 and 3, respectively, in the fair value hierarchy. The income approach involves the use of a discounted cash flow method, with the cash flow projections discounted at an appropriate discount rate. The market approach involves the use of comparable public companies’ market multiples in estimating the fair value. Significant assumptions include projected revenue growth, capital expenditures, utilization, gross margins, discount rates, terminal growth rates, and weight allocation between income and market approaches. If the reporting unit’s carrying amount exceeds its fair value, we consider goodwill impaired, and the impairment loss is calculated and recorded in the period. There were no additions to, or disposal of, goodwill during the years ended December 31, 2021, 2020 and 2019. In the first quarter of 2020, the depressed crude oil prices and crude oil storage challenges faced in the U.S. oil and gas industry triggered the Company to perform an interim goodwill impairment test, and as a result, we compared the carrying value of the goodwill in our hydraulic fracturing reporting unit with the estimated fair value. Our interim impairment test also considered other relevant factors, including market capitalization and market participants’ view of the oil and gas industry in reaching our conclusion that the carrying value of our goodwill in our pressure pumping reportable segment of $ 9.4 million was fully impaired during the first quarter of 2020. Accordingly, we recorded a goodwill impairment expense of $ 9.4 million in March 2020, resulting in a full write off of our goodwill. There were no good will impairment during the year ended December 31, 2019. 61 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 5.

LONG‑TERM DEBT Asset-Based Loan ( " ABL ") Credit Facility Our revolving credit facility ("ABL Credit Facility"), as amended, has a total borrowing capacity of $ 300 million (subject to the Borrowing Base limit), with a maturity date of December 19, 2023. The ABL Credit Facility has a borrowing base of 85 % of monthly eligible accounts receivable less customary reserves (the "borrowing base"), as redetermined monthly. The borrowing base as of December 31, 2021 was approximately $ 61.1 million. The ABL Credit Facility includes a Springing Fixed Charge Coverage Ratio to apply when excess availability is less than the greater of (i) 10 % of the lesser of the facility size or the borrowing base or (ii) $ 22.5 million. Under this facility we are required to comply, subject to certain exceptions and materiality qualifiers, with certain customary affirmative and negative covenants, including, but not limited to, covenants pertaining to our ability to incur liens, indebtedness, changes in the nature of our business, mergers and other fundamental changes, disposal of assets, investments and restricted payments, amendments to our organizational documents or accounting policies, prepayments of certain debt, dividends, transactions with affiliates, and certain other activities. Borrowings under the ABL Credit Facility are secured by a first priority lien and security interest in substantially all assets of the Company. Borrowings under the ABL Credit Facility accrue interest based on a three-tier pricing grid tied to availability, and we may elect for loans to be based on either LIBOR or base rate, plus the applicable margin, which ranges from 1.75 % to 2.25 % for LIBOR loans and 0.75 % to 1.25 % for base rate loans, with a LIBOR floor of zero . The loan origination costs relating to the ABL Credit Facility are classified as an asset in the balance sheet. There were no borrowings under the ABL Credit Facility as of December 31, 2021, and 2020. 7.

EMPLOYEE BENEFIT PLAN The Company has a 401(k) plan, modified effective January 1, 2019, and the Company matches 100 % of the employee contributions up to 6 % of gross salary, up to the annual limit. The employees vest in the Company contributions to the 401(k) plan 25 % per year, beginning in the employee’s first year of service, with full vesting occurring after four years of service. The employees are fully vested in their contributions when made. Effective April 1, 2022, the Company modified its 401(k) plan to allow for immediate vesting of the Company’s contributions. During the years ended December 31, 2021, 2020 and 2019, the recorded expense under the plan was $ 2.8 million, $ 2.1 million and $ 3.0 million, respectively. 9. REPORTABLE SEGMENT INFORMATION The Company has three operating segments for which discrete financial information is readily available: hydraulic fracturing (inclusive of acidizing), cementing and coiled tubing. These operating segments represent how the Chief Operating Decision Maker evaluates performance and allocates resources. In December 2021, the Company disposed of two turbine generators included in our pressure pumping reportable segment for total cash proceeds of approximately $ 36.0 million. The net book value of the two turbines prior to the disposal was approximately $ 39.5 million, resulting in loss on disposal of approximately $ 3.5 million. In September 2020, the Company shut down its drilling operations and disposed of all of its drilling rigs and ancillary assets for approximately $ 0.5 million. In March 2020, the Company shut down its flowback operating segment and subsequently disposed of the assets for approximately $ 1.6 million. Our drilling and flowback operations were included in our “all other” category. The shutdown of the drilling and flowback operations resulted in a reduction in the number of our current operating segments to three . The change in the number of our operating segments did not impact our reportable segment information reported for the years presented. In accordance with FASB ASC 280— Segment Reporting , the Company has one reportable segment (pressure pumping) comprised of the hydraulic fracturing and cementing operating segments. The coiled tubing operating segment and corporate administrative expense (inclusive of our total income tax expense (benefit), other (income) and expense and interest expense) are included in the "all other" category in the tables below. Total corporate administrative expense for the years ended December 31, 2021, 2020 and 2019 was $ 38.5 million , $ 31.6 million and $ 113.0 million, respectively. Our hydraulic fracturing operating segment revenue approximated 93.3 %, 94.2 % and 95.6 % of our pressure pumping revenue for the years ended December 31, 2021, 2020 and 2019, respectively. Inter-segment revenues are not material and are not shown separately in the table below. The Company manages and assesses the performance of the reportable segment by its adjusted EBITDA (earnings before other income (expense), interest expense, income taxes, depreciation and amortization, stock-based compensation expense, severance and related expense, impairment expense, (gain)/loss on disposal of assets and other unusual or nonrecurring expenses or (income)). 63 PROPETRO HOLDING CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 12. INCOME TAXES (Continued) Deferred tax assets and liabilities are recognized for estimated future tax effects of temporary differences between the tax basis of an asset or liability and its reported amount in the consolidated financial statements. The significant items giving rise to deferred tax assets (liabilities) are as follows: ($ in thousands) December 31, 2021 2020 Deferred Income Tax Assets Accrued liabilities $ 911 $ 472 Allowance for credit losses 46 316 Goodwill and other intangible assets 2,161 3,408 Stock‑based compensation 3,382 4,015 Net operating losses 87,822 85,827 Other 56 56 Total deferred tax assets 94,378 94,094 Valuation allowance ( 1,693 ) ( 868 ) Total deferred tax assets — net $ 92,685 $ 93,226 Deferred Income Tax Liabilities Property and equipment $ ( 152,624 ) $ ( 166,494 ) Prepaid expenses ( 1,113 ) ( 2,073 ) Total deferred tax liabilities $ ( 153,737 ) $ ( 168,567 ) Net deferred tax liabilities $ ( 61,052 ) $ ( 75,341 ) The Tax Cuts and Jobs Act (the "TCJA") included a reduction to the maxi mum deduction allo wed for net o perating losses generated in tax years after December 31, 2017 and the elimination of carrybacks of net operating losses. Under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, which modified the TCJA, U.S. federal net operating loss carryforwards ( " NOLs " ) generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such NOLs in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. As of December 31, 2021, the Company had approximately $ 408.0 million of federal NOLs some of which will begin to expire in 2035. Approximately $ 219.5 million of the Company’s federal NOLs relate to pre-2018 periods. As of December 31, 2021, the Company’s state net operating losses were approximately $ 50.1 million and will begin to expire in 2024. Utilization of net operating loss carryforwards may be limited due to past or future ownership changes. As of December 31, 2021, we determined that $ 1.7 million valuation allowance was necessary against our state deferred tax assets. The Company’s U.S. federal income tax returns for the y ear ended December 31, 2018, and through the most recent filing remain open to examination by the Internal Revenue Service under the applicable U.S. federal statute of limitations provisions. The various states in which the Company is subject to income tax are generally open to examination for the tax years ended December 31, 2017, and through the most recent filing. The Company records uncertain tax positions in accordance with ASC 740, Income Taxes, on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than fifty percent likely to be realized upon ultimate settlement with the related tax authority. As of December 31, 2021, 2020 and 2019, no uncertain tax positions were recorded. The Company will continue to evaluate its tax positions in accordance with ASC 740 and will recognize any future effect as either a benefit or charge to income in the applicable period. Income tax penalties and interest assessments recognized under ASC 740 are accrued as a tax expense in the period that the Company’s taxes are in an uncertain tax position. Any accrued tax penalties or interest assessments will remain until the uncertain tax position is resolved with the taxing authorities or until the applicable statute of limitations has expired. 13. RELATED‑PARTY TRANSACTIONS 71 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 13. RELATED-PARTY TRANSACTIONS (Continued) Corporate Office Building Prior to April 2020, the Company rented its corporate office building and the associated real property from an entity, in which a former executive officer of the Company has an equity interest for approximately $ 0.1 million per year. In April 2020, the Company acquired the corporate office building and associated real property for approximately $ 1.5 million. Operations and Maintenance Yards The Company also rents five yards from an entity, in which certain former executive officers and a director of the Company have equity interests and total annual rent expense for each of the five yards was approximately $ 0.03 million, $ 0.03 million, $ 0.1 million, $ 0.1 million, and $ 0.2 million, respectively. The Company also leased its drilling yard from another entity, in which a certain former executive officer of the Company has an equity interest, for an annual lease expense of approximately $ 0.1 million during 2020 . In November 2020, we terminated the drilling yard lease. Equipment Rental and Other Services The Company obtained equipment maintenance services from an entity that has a family relationship with an executive officer of the Company. During the year ended December 31, 2021 and 2020, the Company incurred approximately $ 0 and $ 1.2 million, respectively, for equipment maintenance services associated with this related party. At December 31, 2021 and 2020, the Company had no outstanding payables or receivables to or from the above related party. Pioneer On December 31, 2018, we consummated the Pioneer Pressure Pumping Acquisition. In connection with the Pioneer Pressure Pumping Acquisition, Pioneer received 16.6 million shares of our common stock and approximately $ 110.0 million in cash. Revenue from services provided to Pioneer (including idle fees) accounted for approximately $ 473.8 million, $ 335.4 million and $ 524.2 million of our total revenue during the years ended December 31, 2021, 2020 and 2019, respectively. In connection with the Pioneer Pressure Pumping Acquisition, the Company agreed to reimburse Pioneer for a certain portion of the retention bonuses paid to former Pioneer employees that were subsequently employed by the Company. During years ended December 31, 2021, 2020 and 2019, the Company fully reimbursed Pioneer approximately $ 0 , $ 2.7 million and $ 4.2 million respectively. As of December 31, 2021, the total accounts receivable due from Pioneer, including estimated unbilled receivable for services (including idle fees) we provided, amounted to $ 62.1 million a nd the amount due to Pioneer was $ 0 . As of December 31, 2020, the balance due from Pioneer for services (including idle fees) we provided amo unted to approximately $ 41.7 million and the amount due to Pioneer was $ 0 . 14. LEASES On January 1, 2019, we implemented ASC 842, using the modified retrospective transition method and elected not to restate prior years. Accordingly, the effects of adopting ASC 842 were adjusted in the beginning of 2019 while prior periods are accounted for under the legacy GAAP, ASC 840. There was no cumulative effect adjustment on beginning retained earnings. We also elected other practical expedients provided by the new lease standard, the short-term lease recognition practical expedient in which leases with a term of twelve months or less will not be recognized on the balance sheet and the practical expedient to not separate lease and non-lease components for real estate class of assets. Our discount rate was based on our estimated incremental borrowing rate on a collateralized basis with similar terms and economic considerations as our lease payments at the lease commencement. Below is a description of our operating and finance leases. 72 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 14. LEASES (Continued) Operating Leases Description of Lease In March 2013, we entered into a ten-year real estate lease contract (the “Real Estate Lease”) with a commencement date of April 1, 2013, as part of the expansion of our equipment yard. The lease is with an entity in which a former director of the Company has a noncontrolling equity ownership interest. For the years ended December 31, 2021, 2020 and 2019, the Company made lease payments of approximately $ 0.4 million , $ 0.4 million and $ 0.4 million, respectively. The assets and liabilities under this contract are equally allocated between our cementing and coiled tubing segments. In addition to the contractual lease period, the contract includes an optional renewal of up to ten years , and in management’s judgment the exercise of the renewal option is not reasonably assured. The contract does not include a residual value guarantee, covenants or financial restrictions. Further, the Real Estate Lease does not contain variability in payments resulting from either an index change or rate change. Effective January 1, 2019, the remaining lease term in our present value estimate of the minimum future lease payments was approximately four years . We accounted for our Real Estate Lease to be an operating lease. Our assumptions resulted from the existence of the right to control the use of the assets throughout the lease term. We did not account for the land separately from the building of the real estate lease because we concluded that the accounting effect was insignificant. As of December 31, 2021, the weighted average discount rate and remaining lease term was 6.7 % and 1.3 years, re spectively. As of December 31, 2021, our total operating lease right-of-use asset cost wa s $ 1.2 million, and accumulated amortization was $ 0.8 million. As of December 31, 2020, our total operating lease right-of-use ass et cost was $ 1.2 million, and accumulated amortization was $ 0.5 million. For the years ended December 31, 2021, 2020 and 2019 we recorded operating lease cost of $ 0.3 million, $ 0.3 million and $ 0.4 million respectively, in our statement of operations. Finance Leases Description of Ground Lease In 2018, we entered into a ten-year land lease contract (the “Ground Lease”) with an exclusive option to purchase the land exercisable beginning one year from the commencement date of October 1, 2018 through the end of the contractual lease term. In March 2020, the Company exercised its option and purchased the land associated with the Ground Lease for approximately $ 2.5 million. The maturity analysis of liabilities and reconciliation to undiscounted and discounted remaining future lease payments for operating lease as of December 31, 2021 are as follows: ($ in thousands) Totals 2022 $ 389 2023 98 Total undiscounted future lease payments 487 Amount representing interest ( 21 ) Present value of future lease payments (lease obligation) $ 466 The total cash paid for amounts included in the measurement of our operating lease liability during the year ended December 31, 2021 was approximately $ 0.4 million . During the year ended December 31, 2020, the total cash paid for amounts included in the measurement of our operating and finance lease liabilities was approximately $ 0.4 million and $ 0.03 million, respectively. The non-cash lease obligation we recorded effective January 1, 2019, upon adopting the new lease standard, ASC 842, was $ 2.0 million and $ 3.1 million for operating and finance leases, respectively. 73 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 14. LEASES (Continued) Short-Term Leases We elected the practical expedient, consistent with ASC 842, to exclude leases with an initial term of twelve months or less ("short-term lease") from our balance sheet and continue to record short-term leases as a period expense. For the years ended December 31, 2021 and 2020, our short-term asset lease expense was approximately $ 0.6 million and $ 1.0 million, respectively. In April 2021, we entered into a short-term lease arrangement to lease our turbine (the “Equipment Lease”) with a commencement date of June 1, 2021 through September 30, 2021. We classified the Equipment Lease as an operating lease, and during the year ended December 31, 2021, we recognized approximately $ 3.0 million in lease income recorded as part of our pressure pumping segment revenue on our statements of operat ions. 15. 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. As of December 31, 2021, t here were no outstanding contractual commitments. At December 31, 2021, the total remaining commitments and other obligations for all of our short-term lease and l odging arrangements was $ 3.7 million . 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 a certain percentage of our sand requirements from our customers or in certain situations based on predetermined fixed minimum volumes, otherwise certain penalties (shortfall fees) may be charged. The shortfall fee represents liquidated damages and is either a fixed percentage of the purchase price for the mi nimum volumes or a fixed price per ton of unpurchased volumes. Our agreements with Sand Suppliers expire at different times prior to December 31, 2025. During the years ended December 31, 2021, 2020 and 2019, no shortfall fee was recorded. However, one of our Sand Suppliers has filed a suit against us that includes claims related to alleged shortfall fees. The suit is in the early stages, and we are contesting the claims. While we cannot reasonably estimate the outcome of the matter at this time, in the opinion of management, the ultimate disposition of the action will not have a materially adverse effect on the Company. One of the Sand Suppliers ( " SandCo " ) we entered into an agreement to purchase sand ( " Texas Sand " ) has an indirect relationship with a former executive officer of the Company, because beginning in 2018, the Texas Sand was sourced from a mine located on land owned by an entity in which the former executive officer of the Company has a 44 % noncontrolling equity interest. The total sand purchased from SandCo during the three months ended March 31, 2020 (the period the former executive was associated with the Company) was approximately $ 5.3 million. As of December 31, 2021 and 2020, the Company had issued le tters of credit of $ 3.7 million and $ 3.7 million, respectively, under the ABL Credit Facility in connection with the Company's casualty insurance policy. Contingent Liabilities Legal Matters In September 2019, a complaint, captioned Richard Logan, Individually and On Behalf of All Others Similarly Situated, Plaintiff, v. ProPetro Holding Corp., et al., (the "Logan Lawsuit"), was filed against the Company and certain of its then current and former officers and directors in the U.S. District Court for the Western District of Texas. In July 2020, the Logan Lawsuit Lead Plaintiffs Nykredit Portefølje Administration A/S, Oklahoma Firefighters Pension and Retirement System, Oklahoma Law Enforcement Retirement System, Oklahoma Police Pension and Retirement System, and Oklahoma City Employee Retirement System, and additional named plaintiff Police and Fire Retirement System of the City of Detroit, individually and on behalf of a putative class of shareholders who purchased the Company’s common stock between March 17, 2017 and March 13, 2020, filed a 74 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 15. COMMITMENTS AND CONTINGENCIES (Continued) third amended class action complaint in the U.S. District Court for the Western District of Texas, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule l0b-5 promulgated thereunder, and Sections 11 and 15 of the Securities Act of 1933, as amended, based on allegedly inaccurate or misleading statements, or omissions of material facts, about the Company’s business, operations and prospects against the Company, and certain of its current and former officers and directors. On September 13, 2021, the Court partially granted and partially denied motions to dismiss filed by the Company and the individual defendants. Discovery is still ongoing. In May 2020, the U.S. District Court for the Western District of Texas consolidated two shareholder derivative lawsuits previously filed against the Company and certain of its current and former officers and directors into a single lawsuit captioned In re ProPetro Holding Corp. Derivative Litigation (the “Shareholder Derivative Lawsuit”). In August 2020, the plaintiffs in the Shareholder Derivative Lawsuit filed a consolidated complaint alleging (i) breaches of fiduciary duties, (ii) unjust enrichment and (iii) contribution. The plaintiffs did not quantify any alleged damages in its complaint but, in addition to attorneys’ fees and costs, they seek various forms of relief, including (i) damages sustained by the Company as a result of the alleged misconduct, (ii) punitive damages and (iii) equitable relief in the form of improvements to the Company’s governance and controls. On September 15, 2021, the Court granted the Company's motion to dismiss the complaint in its entirety, without prejudice. On November 19, 2021, the Company received a demand letter from a law firm representing one of the purported shareholders of the Company that previously filed the dismissed Shareholder Derivative Lawsuit. The demand letter alleged facts and claims substantially similar to the Shareholder Derivative Lawsuit. The Board of Directors has constituted a committee to evaluate the demand letter and recommend a course of action to the Board of Directors, and the committee has retained counsel to assist with its review. The committee’s review is ongoing. In October 2019, the Company received a letter from the SEC indicating that the SEC had opened an investigation into the Company, which followed the SEC’s issuance of a formal order of investigation, and requesting that the Company provide certain information and documents, including documents related to the Company's expanded audit committee review and related events. In November 2021, the Company entered a settlement with the SEC resolving the investigation. The Company was not required to pay any monetary penalty and has no ongoing undertakings in connection with the settlement. We are presently unable to predict the duration, scope or result of the Logan Lawsuit, or any other related lawsuit or investigation. As of December 31, 2021, no provision was made by the Company in connection with this pending lawsuit as the final outcome cannot be reasonably estimated. Environmental and Equipment Insurance 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. Effective November 2021 and in connection with our equipment insurance program renewal, the Company will self-insure up to $ 10 million per occurrence for certain losses arising from or attributable to fire and/or explosion at the wellsites. 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. As of December 31, 2021, the audit is still ongoing and the final outcome cannot be reasonably estimated. 75 PROPETRO HOLDING CORP. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 15. COMMITMENTS AND CONTINGENCIES (Continued) In January 2022, we entered into a settlement agreement with the Comptroller for a $ 10.7 million tax refund, net of consulting fees, in connection with certain limited sales and use tax for the audit period July 1, 2015 through December 31, 2018. The net refund will be recorded in our first quarter of 2022, the period the refund is expected to be received by the Company. During the year December 31, 2021, the net refund received by the Company from the sales and excise and use tax audit was approximately $ 2.1 million, which was recorded as part of other income in the statement of operations . 16.
