CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

          This Quarterly Report on Form 10-Q (this "Form 10-Q") contains forward-looking statements that are intended to be covered by the safe harbor provided by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts contained in this Form 10-Q are forward-looking statements within the meaning of Section 21E of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements are all statements other than statements of historical facts, and give our expectations or forecasts of future events as of the effective date of this Form 10-Q. Words such as "may," "could," "plan," "project," "budget," "predict," "pursue," "target," "seek," "objective," "believe," "expect," "anticipate," "intend," "estimate," "will," "should" and similar expressions are generally to identify forward-looking statements. These statements include, but are not limited to statements about our business strategy, industry, future profitability and future capital expenditures. Such statements are subject to risks and uncertainties, many of which are difficult to predict and generally beyond our control, that could cause actual results to differ materially from those implied or projected by the forward-looking statements. Factors that could cause our actual results to differ materially from those contemplated by such forward-looking statements include:

•the severity and duration of current world health events and armed conflict, including the coronavirus ("COVID-19") pandemic and the Russian-Ukraine war and associated repercussions to supply and demand for oil and gas and the economy generally;

•the actions taken by the members of the Organization of the Petroleum Exporting Countries ("OPEC") and Russia (together with OPEC and other allied producing countries, "OPEC+") with respect to oil production levels and announcements of potential changes in such levels, including the ability of the OPEC+ countries to agree on and comply with supply limitations;

•actions taken by the Biden Administration, such as executive orders or new regulations, that may negatively impact the future production of oil and natural gas in the United States and may adversely affect our future operations;

•the level of production and resulting market prices for crude oil, natural gas and other hydrocarbons;

•changes in general economic and geopolitical conditions, including the rate of inflation;

•the effects of existing and future laws and governmental regulations (or the interpretation thereof) on us and our customers;

•cost increases and supply chain constraints related to our services;

•competitive conditions in our industry;

•changes in the long-term supply of, and demand for, oil and natural gas;

•actions taken by our customers, suppliers, competitors and third-party operators and the possible loss of customers or work to our competitors;

•technological changes, including lower emissions oilfield services equipment and similar advancements;

•changes in the availability and cost of capital;

•our ability to successfully implement our business plan;

•large or multiple customer defaults, including defaults resulting from actual or potential insolvencies;

•the effects of consolidation on our customers or competitors;

•the price and availability of debt and equity financing (including changes in interest rates) for the Company and our customers;

•our ability to complete growth projects on time and on budget;

•operational challenges relating to the COVID-19 pandemic and efforts to mitigate the spread of the virus, including logistical challenges, protecting the health and well-being of our employees, remote work arrangements, performance of contracts and supply chain disruptions;

•changes in our tax status;

•regulatory and related policy actions intended by federal, state and/or local governments to reduce fossil fuel use and associated carbon emissions, or to drive the substitution of renewable forms of energy for oil and gas, may over time reduce demand for oil and gas and therefore the demand for our services;

-ii-

•new or expanded regulations that materially limit our customers’ access to federal and state lands for oil and gas development, thereby reducing demand for our services in the affected areas;

•growing demand for electric vehicles that result in reduced demand for gasoline and therefore the demand for our services;

•our ability to successfully implement technological developments and enhancements, including our new Tier IV DGB equipment and other lower-emissions equipment we may acquire or that may be sought by our customers;

•operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control, which risks may be self-insured, or may not be fully covered under our insurance programs;

•acts of terrorism, war or political or civil unrest in the United States or elsewhere;

•the effects of current and future litigation, including the Logan Lawsuit; and

•the potential impact on our business and stock price of any announcements regarding the Logan Lawsuit.

          Whether actual results and developments will conform with our expectations and predictions contained in forward-looking statements is subject to a number of risks and uncertainties which could cause actual results to differ materially from such expectations and predictions, including, without limitation, in addition to those specified in the text surrounding such statements, the risks described under Part II, Item 1A, "Risk Factors" in this Form 10-Q and elsewhere throughout this report, the risks described under Part I, Item 1A, "Risk Factors" in our Form 10-K for the year ended December 31, 2021, filed with the SEC (the "Form 10-K") and elsewhere throughout that report, and other risks, many of which are beyond our control.

          Readers are cautioned not to place undue reliance on our forward-looking statements, which are made as of the date of this Form 10-Q. We do not undertake, and expressly disclaim, any duty to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by applicable securities laws. Investors are also advised to carefully review and consider the various risks and other disclosures discussed in our SEC reports, including the risk factors described in the Form 10-K.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 - Basis of Presentation

          The accompanying condensed consolidated financial statements of ProPetro Holding Corp. and its subsidiary (the "Company," "we," "us" or "our") have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission ("SEC") for interim financial information and do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for annual financial statements. Those adjustments (which consisted of normal recurring accruals) that are, in the opinion of management, necessary for a fair presentation of the results of the interim periods have been made. Results of operations for such interim periods are not necessarily indicative of the results of operations for a full year due to changes in market conditions and other factors. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2021, included in our Form 10-K filed with the SEC (our "Form 10-K").

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 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 reservation or idle fee charges if a customer were to reserve or idle committed hydraulic fracturing equipment. The Company recognizes revenue related to idle or reservation fee charges on a daily basis or monthly 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 the 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 March 31, 2022, and December 31, 2021, accrued revenue (unbilled receivable) included as part of our accounts receivable was $70.6 million and $19.4 million,

Note 1 - Basis of Presentation (Continued)

respectively. At March 31, 2022, the transaction price allocated to the remaining performance obligation for our partially completed hydraulic fracturing operations was $35.5 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.

Allowance for Credit Losses

          As of March 31, 2022, 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 the expected impact of any potential deteriorating economic conditions in the oil and gas industry. We evaluated the historic loss experience on our accounts receivable and also separately considered customers with receivable balances that could be negatively impacted by current 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.

          The table below shows a summary of allowance for credit losses during the three months ended March 31, 2022:

Note 2 - Recently Issued Accounting Standards

Recently Issued Accounting Standards Adopted in 2022

            In March 2020, the Financial Accounting Standards Board ("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. Effective January 1, 2022, we adopted this guidance, and the adoption did not materially affect the Company’s condensed consolidated financial statements.

Note 3 - Fair Value Measurement

           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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 3 - Fair Value Measurement (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 March 31, 2022 and December 31, 2021, approximated or equaled their carrying values as reflected in our condensed consolidated balance sheets.

Assets Measured at Fair Value on a Nonrecurring Basis

          No assets were measured at fair value on a nonrecurring basis as of March 31, 2022 and December 31, 2021, respectively.

          No impairment of property and equipment was recorded during the three months ended March 31, 2022 and 2021.

         Our DuraStim® equipment is yet to be commercialized. If we are not able to successfully commercialize the DuraStim® equipment, and are not able to deploy the equipment for alternative uses, we will incur impairment losses on the carrying value of the DuraStim® equipment. As of March 31, 2022, the carrying value of our DuraStim® equipment is approximately $88 million.

Note 4 - Long-Term Debt

Asset-Based Loan ("ABL") Credit Facility

          Our revolving credit facility, as amended in 2018, had a total borrowing capacity of $300.0 million (subject to the borrowing base limit), with a maturity date of December 19, 2023. The revolving credit facility had a borrowing base of 85% of monthly eligible accounts receivable less customary reserves, as redetermined monthly. The borrowing base under our revolving credit facility, as amended in 2018, was $60.1 million as of March 31, 2022. The revolving credit facility, included a springing fixed charge coverage ratio to apply when excess availability was less than the greater of (i) 10% of the lesser of the facility size or the borrowing base or (ii) $22.5 million. Borrowings under this revolving credit facility accrued interest based on a three-tier pricing grid tied to availability, and we had the option to elect for loans to be based on either LIBOR or base rate, plus the applicable margin, which ranged 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.

          Effective April 13, 2022, the Company entered into an amendment of its revolving credit facility (as amended and restated, "ABL Credit Facility"). The ABL Credit Facility decreased the borrowing capacity to $150.0 million (subject to the Borrowing Base (as defined below) limit), with a maturity date extended to April 13, 2027. The ABL Credit Facility has a borrowing base of 85% to 90%, depending on the credit ratings of our accounts receivable counterparties, of monthly eligible accounts receivable less customary reserves (the "Borrowing Base"), as redetermined monthly. The Borrowing Base as of April 30, 2022, was approximately $86.6 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) $10.0 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 the Secured Overnight Financing Rate ("SOFR") or the base rate, plus the applicable margin, which ranges from 1.50% to 2.00% for SOFR loans and 0.50% to 1.00% for base rate loans.

          The loan origination costs relating to the ABL Credit Facility are classified as an asset in our balance sheet. There were no borrowings under the revolving credit facility as of March 31, 2022 and December 31, 2021.

Note 5 - 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 accordance with the FASB Accounting Standards Codification ("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 table below. Total corporate administrative expense for the three months ended March 31, 2022 and 2021 was $17.3 million and $5.0 million, respectively.

          Our hydraulic fracturing operating segment revenue approximated 93.6% and 93.3% of our pressure pumping revenue during the three months ended March 31, 2022 and 2021, respectively.

          Inter-segment revenues are not material and are not shown separately in the table below.

Note 6 - Net Income (Loss) Per Share

          Basic net income (loss) per common share is computed by dividing the net income (loss) relevant to the common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share uses the same net income (loss) divided by the sum of the weighted average number of shares of common stock outstanding during the period, plus dilutive effects of options, performance and restricted stock units outstanding during the period calculated using the treasury method and the potential dilutive effects of preferred stocks (if any) calculated using the if-converted method.

Restricted Stock Units

         During the three months ended March 31, 2022, we granted 560,274 restricted stock units ("RSUs") to employees, officers and directors pursuant to the ProPetro Holding Corp. 2020 Long Term Incentive Plan (the "2020 Incentive Plan"), which generally vest ratably over a three-year vesting period, in the case of awards to employees and officers, and generally vest in full after one year, in the case of awards to directors. RSUs are subject to restrictions on transfer and are generally subject to a risk of forfeiture if the award recipient ceases to be an employee or director of the Company prior to vesting of the award. Each RSU represents the right to receive one share of common stock. The grant date fair value of the RSUs is based on the closing share price of our common stock on the date of grant. As of March 31, 2022, the total unrecognized compensation expense for all RSUs was approximately $11.3 million, and is expected to be recognized over a weighted average period of approximately 2.3 years.

        On March 31, 2022, the Company modified the RSUs previously granted to a former officer in 2019, 2020 and 2021 to accelerate the vesting of such RSUs in connection with his separation agreement. As a result of this modification, we recorded an incremental stock expense of $1.3 million during the three months ended March 31, 2022.

          The following table summarizes RSUs activity during the three months ended March 31, 2022 (in thousands, except for weighted average fair value):

Performance Share Units

           During the three months ended March 31, 2022, we granted 327,939 performance share units ("PSUs") to certain key employees and officers as new awards under the 2020 Incentive Plan. Each PSU earned represents the right to receive either one share of common stock or, as determined by the administrator in its sole discretion, a cash amount equal to fair market value of one share of common stock or amount of cash on the day immediately preceding the settlement date. The actual number of shares of common stock that may be issued under the PSUs ranges from 0% up to a maximum of 200% of the target number of PSUs granted to the participant, based on our total shareholder return ("TSR") relative to a designated peer group, generally at the end of a three year period. In addition to the TSR conditions, vesting of the PSUs is generally subject to the

recipient’s continued employment through the end of the applicable performance period. Compensation expense is recorded ratably over the corresponding requisite service period. The grant date fair value of PSUs is determined using a Monte Carlo probability model. Grant recipients do not have any shareholder rights until performance relative to the peer group has been determined following the completion of the performance period and shares have been issued.

         In connection with a former officer’s separation agreement, on March 31, 2022, the Company modified the PSUs previously granted to such former officer in 2020 and 2021 to provide for deemed satisfaction of the service requirement applicable to such PSUs as of March 31, 2022, such that such PSUs shall remain outstanding and eligible to vest based on our TSR relative to a designated peer group over the applicable performance period. As a result of these modifications, we recorded an incremental stock expense of $3.7 million during the three months ended March 31, 2022.

 The following table summarizes information about PSUs activity during the three months ended March 31, 2022 (in thousands, except for weighted average fair value):

Period Granted	Target Shares Outstanding at January 1, 2022		Target Shares Granted		Target Shares Vested		Target Shares Forfeited		Target Shares Outstanding at March 31, 2022		Weighted Average Grant Date FV Per Share

Operations and Maintenance Yards

           The Company rents five yards from an entity, in which certain former executive officers and a director of the Company have equity interests and the 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.

Pioneer

          On December 31, 2018, we consummated the purchase of certain pressure pumping assets and real property from Pioneer Natural Resources USA, Inc. ("Pioneer") and Pioneer Pumping Services (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. On March 31, 2022, we entered into an amended and restated pressure pumping services agreement (the "A&R Pressure Pumping Services Agreement"), which was initially entered into in connection with the Pioneer Pressure Pumping Acquisition. The A&R Pressure Pumping Services Agreement was effective January 1, 2022 and continues through December 31, 2022. The A&R Pressure Pumping Services Agreement reduced the number of contracted fleets to six fleets from eight fleets, modified the pressure pumping scope of work and pricing mechanism for contracted fleets, and replaced the idle fees arrangement with equipment reservation fees (the "Reservation fees"). As part of the Reservation fees arrangement, the Company will be entitled to receive compensation for all eligible contracted fleets that are made available to Pioneer at the beginning of every quarter in 2022 through the term of the A&R Pressure Pumping Services Agreement.

          Revenue from services provided to Pioneer (including idle fees and Reservation fees) accounted for approximately $123.5 million and $86.3 million of our total revenue during the three months ended March 31, 2022 and 2021, respectively.

          As of March 31, 2022, the total accounts receivable due from Pioneer, including estimated unbilled receivable for services we provided, amounted to approximately $79.3 million and the amount due to Pioneer was $0. As of December 31, 2021, the balance due from Pioneer for services we provided amounted to approximately $62.1 million and the amount due to Pioneer was $0.

Note 9 - Leases

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. During the three months ended March 31, 2022 and 2021, the Company made lease payments of approximately $0.1 million and $0.1 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.

         We accounted for our Real Estate Lease as an operating lease. This conclusion 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 March 31, 2022, the weighted average discount rate and remaining lease term was approximately 6.7% and 1.0 year, respectively.

          As part of our expansion of our hydraulic fracturing equipment maintenance program, we entered into a two year maintenance facility real estate lease contract (the "Maintenance Facility Lease") with a commencement date of March 14, 2022. During the three months ended March 31, 2022, the Company made lease payments of approximately $0.03 million. In addition to the contractual lease period, the contract includes an optional renewal for three additional periods of one year each, 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 Maintenance Facility Lease does not contain variability in payments resulting from either an index change or rate change.

         We accounted for our Maintenance Facility Lease as 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 Maintenance Facility Lease because we concluded that the accounting effect was insignificant. As of March 31, 2022, the weighted average discount rate and remaining lease term was approximately 3.4% and 1.9 years, respectively.

          As of March 31, 2022, the total operating lease right-of-use asset cost was approximately $1.9 million, and accumulated amortization was approximately $0.9 million. As of December 31, 2021, our total operating lease right-of-use asset cost was approximately $1.2 million, and accumulated amortization was approximately $0.8 million. For the three months ended March 31, 2022 and 2021, we recorded operating lease cost of approximately $0.1 million and $0.1 million, respectively, in our statement of operations.

Maturity Analysis of Lease Liabilities

          The maturity analysis of liabilities and reconciliation to undiscounted and discounted remaining future lease payments for our operating lease as of March 31, 2022 are as follows:

($ in thousands)	Totals
2022	$	540
2023	398
2024	50
Total undiscounted future lease payments	988
Less: amount representing interest	(33)
Present value of future lease payments (lease obligation)	$	955

          The total cash paid for amounts included in the measurement of our operating lease liability during the three months ended March 31, 2022 was approximately $0.1 million. The non-cash lease obligation we recorded upon execution of the Maintenance Facility Lease was approximately $0.6 million. During the three months ended March 31, 2021, total cash paid for amounts included in the measurement of our operating lease liability was approximately $0.1 million.

Note 9 - 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 three months ended March 31, 2022 and 2021 our short-term lease expense was approximately $0.2 million and $0.2 million, respectively.

Note 10 - 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. At March 31, 2022, the total remaining lease commitments for all of our short-term leases and lodging commitments was approximately $3.1 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 minimum volumes or a fixed price per ton of unpurchased volumes. Our agreements with the Sand Suppliers expire at different times prior to December 31, 2025. During the three months ended March 31, 2022 and 2021, 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.

          As of March 31, 2022, the Company had issued letters of credit of approximately $4.2 million under the revolving credit facility in connection with the Company’s casualty insurance policy. Effective April 13, 2022, the Company's issued letters of credit increased to approximately $5.0 million 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 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 Exchange Act, 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, certain former officers and current and former directors. On September 13, 2021, the Court partially granted and partially denied the 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 their 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 a purported shareholder 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 Company's board of directors (the "Board") has constituted a committee to evaluate the demand letter and recommend a course of action to the Board, and the committee has retained counsel to assist with its review. The committee’s review is ongoing.

           We are presently unable to predict the duration, scope or result of the Logan Lawsuit, or any other related lawsuit or investigation. As of March 31, 2022, 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. No accrual was recorded in our financial statements in connection with this self-insurance strategy.

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 March 31, 2022, the audit is still ongoing and the final outcome cannot be reasonably estimated.

           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, excise and use tax for the audit period July 1, 2015 through December 31, 2018. The net refund to the Company of $10.7 million was recorded as part of other income in our statement of operations during the three months ended March 31, 2022. During the three months ended March 31, 2021, we recorded net refund of approximately $2.1 million.

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

          The financial information, discussion and analysis that follow should be read in conjunction with our consolidated financial statements and the related notes included in the Form 10-K as well as the financial and other information included therein.

          Unless otherwise indicated, references in this "Management's Discussion and Analysis of Financial Condition and Results of Operations" to the "Company," "we," "our," "us" or like terms refer to ProPetro Holding Corp. and its subsidiary.

Overview

          We are a Midland, Texas-based oilfield services company providing hydraulic fracturing and other complementary services to leading upstream oil and gas companies engaged in the exploration and production ("E&P") of North American oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated longstanding customer relationships with some of the region's most active and well-capitalized E&P companies. The Permian Basin is widely regarded as one of the most prolific oil-producing areas in the United States, and we believe we are one of the largest providers of hydraulic fracturing services in the region by hydraulic horsepower ("HHP").

          Our total available HHP as of March 31, 2022, was 1,423,000 HHP, which was comprised of 140,000 HHP of our Tier IV Dynamic Gas Blending ("DGB") equipment, 1,175,000 HHP of conventional Tier II equipment and 108,000 HHP of our DuraStim® electric hydraulic fracturing equipment. Our fleet could range from approximately 50,000 to 80,000 HHP depending on the job design and customer demand at the wellsite. With the industry transition to lower emissions equipment and simultaneous hydraulic fracturing ("Simul-Frac"), in addition to several other changes to our customers' job designs, we believe that our available capacity could decline if we decide to reconfigure our fleets to increase active HHP and backup HHP at the wellsites. In addition, in September 2021, we committed to additional conversions of our Tier II equipment to Tier IV DGB. As such, we entered into a conversion arrangement with our equipment manufacturers for 125,000 HHP of Tier IV DGB equipment and during the period ended March 31, 2022, we received 50,000 HHP of the converted Tier IV DGB equipment and expect to receive the remaining 75,000 HHP at different times through the second quarter of 2022.

          In 2019, we entered into a purchase commitment for 108,000 HHP of DuraStim® electric powered hydraulic fracturing equipment. Our DuraStim® equipment is yet to be commercialized. Given current market conditions, including continued supply chain disruptions and inflation, and other factors impacting further development of DuraStim®, we do not currently anticipate deploying our DuraStim® equipment in its current configuration for additional field trials during 2022. If we are not able to successfully commercialize the DuraStim® equipment, or deploy the equipment for alternative uses, which we are currently evaluating, we will incur impairment losses on the carrying value of the DuraStim® equipment. As of March 31, 2022, the carrying value of our DuraStim® equipment is approximately $88 million. In addition to DuraStim® fleets, we are also evaluating other electric and alternative pressure pumping solutions.

          On December 31, 2018, we consummated the purchase of certain pressure pumping assets and real property from Pioneer Natural Resources USA, Inc. ("Pioneer") and Pioneer Pumping Services (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. On March 31, 2022, we entered into an amended and restated pressure pumping services agreement (the "A&R Pressure Pumping Services Agreement"), which was initially entered into in connection with the Pioneer Pressure Pumping Acquisition. The A&R Pressure Pumping Services Agreement was effective January 1, 2022 and continues through December 31, 2022. The A&R Pressure Pumping Services Agreement reduced the number of contracted fleets to six fleets from eight fleets, modified the pressure pumping scope of work and pricing mechanism for contracted fleets, and replaced the idle fees arrangement with equipment reservation fees (the "Reservation fees"). As part of the Reservation fees arrangement, the Company will be entitled to receive compensation for all eligible contracted fleets that are made available to Pioneer at the beginning of every quarter in 2022 through the term of the A&R Pressure Pumping Services Agreement.

          Our competitors include many large and small oilfield services companies, including Halliburton Company, Liberty Energy Inc., Nextier Oilfield Solutions Inc., Patterson-UTI Energy Inc., RPC, Inc., and a number of private and locally-oriented businesses. The markets in which we operate are highly competitive. To be successful, an oilfield services company must provide services that meet the specific needs of oil and natural gas E&P companies at competitive prices. Competitive factors impacting sales of our services are price, reputation, technical expertise, emissions profile, service and equipment design and quality, and health and safety standards. Although we believe our customers consider all of these factors, we believe price is a key factor in an E&P company's criteria in choosing a service provider. However, we have recently observed the energy industry and our customers shift to lower emissions equipment, which we believe will be an increasingly important factor in an E&P company's selection of a service provider. The transition to lower emissions equipment has been challenging for companies in the service industry because of the significant capital investment required for next generation equipment and the current pricing environment with the service industry, which remains in recovery phase. While we seek to price our services competitively, we believe many of our customers elect to work with us based on our operational efficiencies, productivity,

-18-

equipment quality, reliability, ability to manage multifaceted logistics challenges, commitment to safety and the ability of our people to handle the most complex Permian Basin well completions.

          Our substantial market presence in the Permian Basin positions us well to capitalize on drilling and completion activity in the region. Primarily, our operational focus has been in the Permian Basin's Midland sub-basin, where our customers have operated. However, we have recently increased our operations in the Delaware sub-basin and are well-positioned to support further increases to our activity in this area in response to demand from our customers. Over time, we expect the Permian Basin's Midland and Delaware sub-basins to continue to command a disproportionate share of future North American E&P spending.

          Through our pressure pumping segment (which also includes our cementing operations), we primarily provide hydraulic fracturing services to E&P companies in the Permian Basin. Our hydraulic fracturing fleet has been designed to handle the operating conditions commonly experienced in the Permian Basin and the region's increasingly high-intensity well completions (including Simul-Frac, which involves fracturing multiple wellbores at the same time), which are characterized by longer horizontal wellbores, more stages per lateral and increasing amounts of proppant per well.

           In addition to our core pressure pumping segment operations, which includes our cementing operations, we also offer coiled tubing services. Through our coiled tubing services segment, we seek to create operational efficiencies for our customers, which could allow us to capture a greater portion of their capital spending across the lifecycle of a well.

Commodity Price and Other Economic Conditions

          The oil and gas industry has traditionally been volatile and is influenced by a combination of long-term, short-term and cyclical trends, including domestic and international supply and demand for oil and gas, current and expected future prices for oil and gas and the perceived stability and sustainability of those prices, and capital investments of E&P companies toward their development and production of oil and gas reserves. The oil and gas industry is also impacted by general domestic and international economic conditions such as global supply chain disruptions and inflation, war and political instability in oil producing countries, government regulations (both in the United States and internationally), levels of consumer demand, adverse weather conditions, and other factors that are beyond our control.

        In February 2022, Russia launched a large-scale invasion of Ukraine that has led to significant armed hostilities. As a result, the United States, the United Kingdom, the member states of the European Union and other public and private actors have levied severe sanctions on Russian financial institutions, businesses and individuals. This conflict, and the resulting sanctions, has contributed to significant increases and volatility in the prices for oil and natural gas. The geopolitical and macroeconomic consequences of this invasion and associated sanctions remain uncertain, and such events, or any further hostilities in Ukraine or elsewhere, could severely impact the world economy and the oil and gas industry and may adversely affect our financial condition.

        The global public health crisis associated with the COVID-19 pandemic also has had an adverse effect on global economic activity and the oil and gas industry. Some of the challenges resulting from the COVID-19 pandemic that have impacted our business include restrictions on movement of personnel and associated gatherings, shortage of skilled labor, cost inflation and supply chain disruptions. In light of the COVID-19 pandemic, most companies, including our customers in the Permian Basin, reacted by closely managing their operating budget and exercising capital discipline. In addition, OPEC+ has indicated that they will continue with their plans to manage production levels by gradually increasing crude oil output.

        The Russia-Ukraine war, and the adverse impacts of the COVID-19 pandemic in recent years, have resulted in volatility in supply and demand dynamics for crude oil and associated volatility in crude oil pricing. In 2022, global crude oil prices have exceeded $100 per barrel, which is the highest prices have been in the last ten years. We believe that the recent surge in global crude oil prices is partly due to the lack of reinvestment in the oil and gas industry in the last two years, coupled with adverse impact of the Russia-Ukraine war, which has led to various sanctions in Russian crude oil supply and businesses. With the significant increase in global crude oil prices, including WTI crude oil prices, there has been an increase in the Permian Basin rig count from approximately 179 at the beginning of 2021 to approximately 323 at the end of March 2022, according to Baker Hughes. Following the increase in rig count and WTI crude oil price, the oilfield service industry has experienced increased demand for its pressure pumping services, and improved pricing. As a result of the growing demand for pressure pumping services and significant cost inflation across the industry, we negotiated pricing increases with certain of our customers and effective as of January 1, 2022, we increased pricing for most of our pressure pumping services, depending on job design. Although we are currently operating in an improved pricing environment, the rapid increase in cost inflation and supply chain tightness could adversely impact our future profitability, if we are unable to timely pass-through the cost increases to our customers.

-19-

          Government regulations and investors are demanding the oil and gas industry transition to a lower emissions operating environment, including the upstream and oilfield service companies. As a result, we are working with our customers and equipment manufacturers to transition to a lower emissions profile. Currently, a number of lower emission solutions for pumping equipment, including Tier IV DGB, electric, direct drive gas turbine and other technologies have been developed, and we expect additional lower emission solutions will be developed in the future. We are continually evaluating these technologies and other investment and acquisition opportunities that would support our existing and new customer relationships. The transition to lower emissions equipment is quickly evolving and will be capital intensive. Over time, we may be required to convert substantially all of our conventional Tier II equipment to lower emissions equipment. If we are unable to quickly transition to lower emissions equipment and meet our and our customers’ emissions goals, the demand for our services could be adversely impacted.

          The Permian Basin rig count increase, WTI crude oil price increase and costs inflation could be indicative of an energy market recovery. If the rig count and market conditions continue to improve, including improved customers' pricing and labor availability, and we are able to meet our customers' lower emissions equipment demands, we believe our operational and financial results will also continue to improve. However, if market conditions do not improve, and we are unable to increase our pricing or pass-through future cost increases to our customers, there could be a material adverse impact on our business, results of operations and cash flows.

          Our results of operations have historically reflected seasonal tendencies, typically in the fourth quarter, relating to the holiday season, inclement winter weather and exhaustion of our customers' annual budgets. As a result, we typically experience declines in our operating and financial results in November and December, even in a stable commodity price and operations environment.

How We Evaluate Our Operations 

          Our management uses Adjusted EBITDA or Adjusted EBITDA margin to evaluate and analyze the performance of our various operating segments.

Adjusted EBITDA and Adjusted EBITDA Margin

          We view Adjusted EBITDA and Adjusted EBITDA margin as important indicators of performance. We define EBITDA as our earnings, before (i) interest expense, (ii) income taxes and (iii) depreciation and amortization. We define Adjusted EBITDA as EBITDA, plus (i) loss/(gain) on disposal of assets, (ii) stock-based compensation, and (iii) other unusual or nonrecurring (income)/expenses, such as impairment charges, severance, costs related to asset acquisitions, insurance recoveries and one-time professional fees on legal settlements. Adjusted EBITDA margin reflects our Adjusted EBITDA as a percentage of our revenues.

          Adjusted EBITDA and Adjusted EBITDA margin are supplemental measures utilized by our management and other users of our financial statements such as investors, commercial banks, and research analysts, to assess our financial performance because it allows us and other users to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense), asset base (such as depreciation and amortization), nonrecurring (income)/expenses and items outside the control of our management team (such as income taxes). Adjusted EBITDA and Adjusted EBITDA margin have limitations as analytical tools and should not be considered as an alternative to net income/(loss), operating income/(loss), cash flow from operating activities or any other measure of financial performance presented in accordance with GAAP.

Note Regarding Non-GAAP Financial Measures

          Adjusted EBITDA and Adjusted EBITDA margin are not financial measures presented in accordance with GAAP ("non-GAAP"), except when specifically required to be disclosed by GAAP in the financial statements. We believe that the presentation of Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors in assessing our financial condition and results of operations because it allows them to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure, asset base, nonrecurring expenses (income) and items outside the control of the Company. Net income (loss) is the GAAP measure most directly comparable to Adjusted EBITDA.  Adjusted EBITDA and Adjusted EBITDA margin should not be considered as alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important limitations as analytical tools because they exclude some, but not all, items that affect the most directly comparable GAAP financial measures. You should not consider Adjusted EBITDA or Adjusted EBITDA margin in isolation or as a substitute for an analysis of our results as reported under GAAP. Because Adjusted EBITDA and Adjusted EBITDA margin may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Results of Operations 

          We conducted our business through three operating segments: hydraulic fracturing, cementing and coiled tubing. For reporting purposes, the hydraulic fracturing and cementing operating segments are aggregated into our one reportable segment—pressure pumping. The coiled tubing operating segment and corporate administrative expenses (inclusive of our total income tax expense (benefit), other (income) and expense and interest expense) are included in the "all other" category. Total corporate administrative expense for the three months ended March 31, 2022 and 2021 was $17.3 million and $5.0 million, respectively.

          Our hydraulic fracturing operating segment revenue approximated 93.6% and 93.3% of our pressure pumping revenue during the three months ended March 31, 2022 and 2021, respectively.

Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021

          Revenues.    Revenues increased 75.1%, or $121.2 million, to $282.7 million during the three months ended March 31, 2022, as compared to $161.5 million during the three months ended March 31, 2021. Our pressure pumping segment revenues increased 75.2%, or $118.9 million, for the three months ended March 31, 2022, as compared to the three months ended March 31, 2021. The increases were primarily attributable to the significant increase in our existing and new customers' activity levels, resulting in higher demand for pressure pumping services and improved pricing. As a result of our customers' increased activity levels, our effectively utilized fleet count rose to approximately 13.7 active fleets during the three months ended March 31, 2022, from approximately 10.3 active fleets for the three months ended March 31, 2021. Included in our revenue for the three months ended March 31, 2022 and 2021 was revenue generated from reservation and idle fees charged to our customer of approximately $6.8 million and $4.3 million, respectively.

          Revenues from services other than pressure pumping increased 70.4%, or $2.3 million, to $5.6 million for the three months ended March 31, 2022, as compared to $3.3 million for the three months ended March 31, 2021. The increase in revenue from services other than pressure pumping was primarily attributable to improved pricing and the increase in utilization experienced by our coiled tubing operations, which was driven by increased E&P completions activity.

          Cost of Services.    Cost of services increased 59.9%, or $73.9 million, to $197.3 million for the three months ended March 31, 2022, as compared to $123.4 million during the three months ended March 31, 2021. Cost of services in our pressure pumping segment increased $72.9 million for the three months ended March 31, 2022, as compared to the three months ended March 31, 2021. These increases were primarily attributable to the significantly increased activity levels resulting from the increased demand for our services. As a percentage of pressure pumping segment revenues (including reservation and idle fees), pressure pumping cost of services was 69.5% for the three months ended March 31, 2022, as compared to 75.7% for the three months ended March 31, 2021. Excluding reservation and idle fees revenue of $6.8 million and $4.3 million recorded during the three months ended March 31, 2022 and 2021, respectively, our pressure pumping cost of services as a percentage of pressure pumping revenues decreased to 71.2% during the three months ended March 31, 2022, as compared to 77.8% for the three months ended March 31, 2021. The decrease in the percentages was a result of increased operational efficiencies, reduction in operational downtime and improved pricing across our customer base.

          General and Administrative Expenses.   General and administrative expenses increased 57.0%, or $11.5 million, to $31.7 million for the three months ended March 31, 2022, as compared to $20.2 million for the three months ended March 31, 2021. The net increase was primarily attributable to an increase during 2022 in (i) stock-based compensation expense of $8.9 million, which was primarily attributable to the non-recurring incremental stock-based compensation associated with the acceleration of stock awards upon resignation of a former executive, (ii) non-recurring legal fees, incurred in connection with pending shareholder litigation, of approximately $2.4 million, and (iii) consulting and professional fees of approximately $1.0 million, which was partially offset by a net decrease of approximately $0.8 million in other general administrative expenses.

          Depreciation and Amortization.    Depreciation and amortization decreased 4.9%, or $1.6 million, to $31.9 million for the three months ended March 31, 2022, as compared to $33.5 million for the three months ended March 31, 2021. The decrease was primarily attributable to the decrease in our fixed asset base, partly attributable to the disposal of certain fixed assets during the period.

          Loss on Disposal of Assets.    Loss on the disposal of assets increased 23.5%, or $3.1 million, to $16.1 million for the three months ended March 31, 2022, as compared to $13.1 million for the three months ended March 31, 2021. The increase was primarily attributable to the significant increase in our utilization levels, resulting in an increase in the operational intensity on our pressure pumping equipment. Upon sale or retirement of property and equipment, including replaced fluid and power ends, the cost and related accumulated depreciation of such assets or components are removed from the balance sheet and the net amount is recognized as loss on disposal of assets.

          Interest Expense.    There was no significant change in interest expense. Interest expense was relatively flat at $0.1 million for the three months ended March 31, 2022, as compared to $0.2 million for the three months ended March 31, 2021. During the three months ended March 31, 2022 and three months ended March 31, 2021, the Company had a zero debt balance, and the interest expense in the three months ended March 31, 2022, and 2021, primarily relates to the amortization of our capitalized loan origination cost.

          Other Income.  Other income increased 478.9%, or $8.6 million, to $10.4 million for the three months ended March 31, 2022, as compared to $1.8 million for the three months ended March 31, 2021. The increase was primarily attributable to the net refund to the Company of $10.7 million from sales, excise and use taxes and partially offset by other expense relating to our lender's commitment fees.

-23-

          Income Taxes.    Total income tax expense was $4.1 million resulting in an effective tax rate of 25.9% for the three months ended March 31, 2022, as compared to income tax benefit of $6.7 million or an effective tax rate of 24.6% for the three months ended March 31, 2021. The change to an income tax expense recorded during the three months ended March 31, 2022, compared to an income tax benefit during the three months ended March 31, 2021, is primarily attributable to the Company projecting a pre-tax income in 2022, as compared to a pre-tax loss in 2021.

Liquidity and Capital Resources

          Our liquidity is currently provided by (i) existing cash balances, (ii) operating cash flows and (iii) borrowings under our ABL Credit Facility (as defined below). Our cash is primarily used to fund our operations, support growth opportunities and satisfy future debt payments, if any. Our Borrowing Base (as defined below), as redetermined monthly, is tied to 85.0% to 90% of eligible accounts receivable. Changes to our operational activity levels and our customers' credit ratings have an impact on our total eligible accounts receivable, which could result in significant changes to our Borrowing Base and therefore our availability under our ABL Credit Facility. We believe our remaining monthly availability under our ABL Credit Facility will be adversely impacted if the current depressed oil and gas market conditions continue or worsen.

           As of March 31, 2022, we had no borrowings under our revolving credit facility, and our total liquidity was approximately $127.2 million, consisting of cash and cash equivalents of $70.8 million and $56.4 million of availability under our revolving credit facility.

           As of April 30, 2022, we had no borrowings under our ABL Credit Facility, and our total liquidity was approximately $144.8 million, consisting of cash and cash equivalents of $63.2 million and $81.6 million of availability under our ABL Credit Facility.

           In 2020, when demand for our services was significantly depressed following the rapidly rising health crisis associated with the COVID-19 pandemic and the energy industry disruptions, the Company experienced a significant decrease in its liquidity. However, with the gradual recovery in the energy industry, improvements in our pricing and an increase in demand for our services, our liquidity position has gradually improved, although we expect our overall liquidity to decline during 2022 as we make additional capital investments. Moreover, the current market conditions resulting from the COVID-19 pandemic have and may in the future change rapidly and there could be a new outbreak of a COVID-19 variant that could result in travel restrictions, business closures and institution of quarantining and/or other activity restrictions, which could negatively impact our future operations, revenue, profitability and cash flows if not contained or if the vaccines currently distributed and administered to people are not as effective as anticipated in curbing the spread of any such new COVID-19 variant.

           The industry transition to lower emissions pressure pumping equipment could require us to make significant investment in DGB or electric solutions in order to continue to meet our current and future customers' equipment demand. If we are unable to timely reinvest in lower emissions equipment, the future demand for our pressure pumping services may be adversely impacted, which could negatively impact our future operations, revenue, profitability and cash flows.

           There can be no assurance that our operations and other capital resources will provide cash in sufficient amounts to maintain planned or future levels of capital expenditures. Future cash flows are subject to a number of variables, and are highly dependent on the drilling, completion, and production activity by our customers, which in turn is highly dependent on oil and natural gas prices. Depending upon market conditions and other factors, we may issue equity and debt securities or take other actions necessary to fund our business or meet our future long-term liquidity requirements.

          Our revolving credit facility, as amended in 2018, had a total borrowing capacity of $300.0 million (subject to the borrowing base limit), with a maturity date of December 19, 2023. The revolving credit facility had a borrowing base of 85% of monthly eligible accounts receivable less customary reserves, as redetermined monthly. The borrowing base under our revolving credit facility, as amended in 2018, was $60.1 million as of March 31, 2022. The revolving credit facility included a springing fixed charge coverage ratio to apply when excess availability was less than the greater of (i) 10% of the lesser of the facility size or the borrowing base or (ii) $22.5 million. Borrowings under the revolving credit facility accrued interest based on a three-tier pricing grid tied to availability, and we had the option to elect for loans to be based on either LIBOR or base rate, plus the applicable margin, which ranged 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. There were no borrowings under the revolving credit facility for the three months ended March 31, 2022.

          Effective April 13, 2022, the Company entered into an amendment of its revolving credit facility (as amended and restated, "ABL Credit Facility"). The ABL Credit Facility decreased the borrowing capacity to $150.0 million (subject to the Borrowing Base limit), with a maturity date extended to April 13, 2027. The ABL Credit Facility has a borrowing base of 85% to 90%, depending on the credit ratings of our accounts receivable counterparties, of monthly eligible accounts receivable less customary reserves (the "Borrowing Base"), as redetermined monthly. The Borrowing Base as of April 30, 2022, was approximately $86.6 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) $10.0 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,

-25-

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 the Secured Overnight Financing Rate ("SOFR") or the base rate, plus the applicable margin, which ranges from 1.50% to 2.00% for SOFR loans and 0.50% to 1.00% for base rate loans.

          The loan origination costs relating to the ABL Credit Facility are classified as an asset in our balance sheet. There were no borrowings under the revolving credit facility as of March 31, 2022, and December 31, 2021.

Future Sources and Use of Cash and Contractual Obligations

         Capital expenditures incurred were $71.7 million during the three months ended March 31, 2022, as compared to $32.3 million during the three months ended March 31, 2021. The significant portion of our total capital expenditures incurred were comprised of primarily maintenance and conversion capital expenditures.

         Our future material use of cash will be to fund our capital expenditures. Capital expenditures for 2022 are projected to be primarily related to maintenance capital expenditures to support our existing pressure pumping assets, costs to convert some existing equipment to lower emissions pressure pumping equipment, strategic purchases and other ancillary equipment purchases, subject to market conditions and customer demand. Our future capital expenditures depend on our projected operational activity, emission requirements and planned conversions to lower emissions equipment, among other factors, which could vary significantly throughout the year. We could incur significant additional capital expenditures if our projected activity levels increase during the course of the year, inflation and supply chain tightness continues to adversely impact our operations or we invest in new or different lower emissions equipment. The Company will continue to evaluate the emissions profile of its fleet over the coming years and may, depending on market conditions, convert or retire additional conventional Tier II equipment in favor of lower emissions equipment. The Company’s decisions regarding the retirement or conversion of equipment or the addition of lower emissions equipment will be subject to a number of factors, including (among other factors) the availability of equipment, including parts and major components, supply chain disruptions, prevailing and expected commodity prices, customer demand and requirements and the Company’s evaluation of projected returns on conversion or other capital expenditures. Depending on the impacts of these factors, the Company may decide to retain conventional equipment for a longer period of time or accelerate the retirement, replacement or conversion of that equipment.

         We anticipate our capital expenditures will be funded by existing cash, cash flows from operations, and if needed, borrowings under our ABL Credit Facility. Our cash flows from operations will be generated from services we provide to our customers.

          In the normal course of business, we enter into various contractual obligations and incur expenses in connection with routine growth and maintenance capital expenditures that impact our future liquidity. There were no other known future material contractual obligations as of March 31, 2022.

Cash and Cash Flows

             The following table sets forth the historical cash flows for the three months ended March 31, 2022, and 2021:

	Three Months Ended March 31,
(in thousands)	2022		2021
Net cash provided by operating activities	$	25,170	$	17,008
Net cash used in investing activities	$	(64,048)	$	(22,270)
Net cash used in financing activities	$	(2,272)	$	(7,651)

Cash Flows From Operating Activities

          Net cash provided by operating activities was $25.2 million for the three months ended March 31, 2022, compared to $17.0 million for the three months ended March 31, 2021. The net increase of approximately $8.2 million was primarily due to the increase in our activity levels resulting from the increase in the demand for our services, driven by increased crude oil prices, net tax refund received, and partially offset with the timing of collections of our receivables from customers and payments to vendors.

-26-

Cash Flows From Investing Activities

          Net cash used in investing activities increased to $64.0 million for the three months ended March 31, 2022, from $22.3 million for the three months ended March 31, 2021. The increase was primarily attributable to our investment in lower emissions Tier IV DGB equipment.

Cash Flows From Financing Activities

          Net cash used in financing activities decreased to $2.3 million for the three months ended March 31, 2022, from $7.7 million for the three months ended March 31, 2021. The net decrease in cash used in financing activities during the three months ended March 31, 2022, was primarily a result of the reduction in the amount of net settlement of equity awards and no repayments of insurance financing in 2022, compared to the three months ended March 31, 2021.

Off-Balance Sheet Arrangements

          We had no off-balance sheet arrangements as of March 31, 2022.

Critical Accounting Policies and Estimates

           There have been no material changes during the three months ended March 31, 2022 to the methodology applied by our management for critical accounting policies previously disclosed in our Form 10-K. Please refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates" in our Form 10-K for a discussion of our critical accounting policies and estimates.

Recently Issued Accounting Standards

          Disclosure concerning recently issued accounting standards is incorporated by reference to Note 2 of our Condensed Consolidated Financial Statements (Unaudited) contained in this Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

          As of March 31, 2022, there have been no material changes in market risk from the information provided in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” or “Quantitative and Qualitative Disclosures of Market Risk” in our Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

         We maintain disclosure controls and procedures that are designed to provide reasonable assurance that the information required to be disclosed by us in our reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

         As required by Rule 13a-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this quarterly report. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2022.

Changes in Internal Control over Financial Reporting

         There were no changes in our system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

          The accompanying condensed consolidated financial statements of ProPetro Holding Corp. and its subsidiary (the "Company," "we," "us" or "our") have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission ("SEC") for interim financial information and do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for annual financial statements. Those adjustments (which consisted of normal recurring accruals) that are, in the opinion of management, necessary for a fair presentation of the results of the interim periods have been made. Results of operations for such interim periods are not necessarily indicative of the results of operations for a full year due to changes in market conditions and other factors. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2021, included in our Form 10-K filed with the SEC (our "Form 10-K").

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 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 reservation or idle fee charges if a customer were to reserve or idle committed hydraulic fracturing equipment. The Company recognizes revenue related to idle or reservation fee charges on a daily basis or monthly 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 the 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 March 31, 2022, and December 31, 2021, accrued revenue (unbilled receivable) included as part of our accounts receivable was $70.6 million and $19.4 million,

respectively. At March 31, 2022, the transaction price allocated to the remaining performance obligation for our partially completed hydraulic fracturing operations was $35.5 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.

Allowance for Credit Losses

          As of March 31, 2022, 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 the expected impact of any potential deteriorating economic conditions in the oil and gas industry. We evaluated the historic loss experience on our accounts receivable and also separately considered customers with receivable balances that could be negatively impacted by current 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.

          The table below shows a summary of allowance for credit losses during the three months ended March 31, 2022:

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

Fair Value Measurement

           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.

          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 March 31, 2022 and December 31, 2021, approximated or equaled their carrying values as reflected in our condensed consolidated balance sheets.

Assets Measured at Fair Value on a Nonrecurring Basis

          No assets were measured at fair value on a nonrecurring basis as of March 31, 2022 and December 31, 2021, respectively.

          No impairment of property and equipment was recorded during the three months ended March 31, 2022 and 2021.

         Our DuraStim® equipment is yet to be commercialized. If we are not able to successfully commercialize the DuraStim® equipment, and are not able to deploy the equipment for alternative uses, we will incur impairment losses on the carrying value of the DuraStim® equipment. As of March 31, 2022, the carrying value of our DuraStim® equipment is approximately $88 million.

Long-Term Debt

Asset-Based Loan ("ABL") Credit Facility

          Our revolving credit facility, as amended in 2018, had a total borrowing capacity of $300.0 million (subject to the borrowing base limit), with a maturity date of December 19, 2023. The revolving credit facility had a borrowing base of 85% of monthly eligible accounts receivable less customary reserves, as redetermined monthly. The borrowing base under our revolving credit facility, as amended in 2018, was $60.1 million as of March 31, 2022. The revolving credit facility, included a springing fixed charge coverage ratio to apply when excess availability was less than the greater of (i) 10% of the lesser of the facility size or the borrowing base or (ii) $22.5 million. Borrowings under this revolving credit facility accrued interest based on a three-tier pricing grid tied to availability, and we had the option to elect for loans to be based on either LIBOR or base rate, plus the applicable margin, which ranged 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.

          Effective April 13, 2022, the Company entered into an amendment of its revolving credit facility (as amended and restated, "ABL Credit Facility"). The ABL Credit Facility decreased the borrowing capacity to $150.0 million (subject to the Borrowing Base (as defined below) limit), with a maturity date extended to April 13, 2027. The ABL Credit Facility has a borrowing base of 85% to 90%, depending on the credit ratings of our accounts receivable counterparties, of monthly eligible accounts receivable less customary reserves (the "Borrowing Base"), as redetermined monthly. The Borrowing Base as of April 30, 2022, was approximately $86.6 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) $10.0 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 the Secured Overnight Financing Rate ("SOFR") or the base rate, plus the applicable margin, which ranges from 1.50% to 2.00% for SOFR loans and 0.50% to 1.00% for base rate loans.

          The loan origination costs relating to the ABL Credit Facility are classified as an asset in our balance sheet. There were no borrowings under the revolving credit facility as of March 31, 2022 and December 31, 2021.

Segment Reporting [Abstract]

Reportable Segment Information

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 accordance with the FASB Accounting Standards Codification ("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 table below. Total corporate administrative expense for the three months ended March 31, 2022 and 2021 was $17.3 million and $5.0 million, respectively.

          Our hydraulic fracturing operating segment revenue approximated 93.6% and 93.3% of our pressure pumping revenue during the three months ended March 31, 2022 and 2021, 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)).

Net Income (Loss) Per Share

          Basic net income (loss) per common share is computed by dividing the net income (loss) relevant to the common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share uses the same net income (loss) divided by the sum of the weighted average number of shares of common stock outstanding during the period, plus dilutive effects of options, performance and restricted stock units outstanding during the period calculated using the treasury method and the potential dilutive effects of preferred stocks (if any) calculated using the if-converted method.

          There were no new stock option grants during the three months ended March 31, 2022. As of March 31, 2022, the aggregate intrinsic value for our outstanding stock options was $2.3 million, and the aggregate intrinsic value for our exercisable stock options was $2.3 million. The aggregate intrinsic value for the exercised stock options during the three months ended March 31, 2022 was approximately $0.8 million. The remaining exercise period for both the outstanding and exercisable stock options as of March 31, 2022 was 3.4 years.

          A summary of the stock option activity for the three months ended March 31, 2022 is presented below (in thousands, except for weighted average price):

Restricted Stock Units

         During the three months ended March 31, 2022, we granted 560,274 restricted stock units ("RSUs") to employees, officers and directors pursuant to the ProPetro Holding Corp. 2020 Long Term Incentive Plan (the "2020 Incentive Plan"), which generally vest ratably over a three-year vesting period, in the case of awards to employees and officers, and generally vest in full after one year, in the case of awards to directors. RSUs are subject to restrictions on transfer and are generally subject to a risk of forfeiture if the award recipient ceases to be an employee or director of the Company prior to vesting of the award. Each RSU represents the right to receive one share of common stock. The grant date fair value of the RSUs is based on the closing share price of our common stock on the date of grant. As of March 31, 2022, the total unrecognized compensation expense for all RSUs was approximately $11.3 million, and is expected to be recognized over a weighted average period of approximately 2.3 years.

        On March 31, 2022, the Company modified the RSUs previously granted to a former officer in 2019, 2020 and 2021 to accelerate the vesting of such RSUs in connection with his separation agreement. As a result of this modification, we recorded an incremental stock expense of $1.3 million during the three months ended March 31, 2022.

          The following table summarizes RSUs activity during the three months ended March 31, 2022 (in thousands, except for weighted average fair value):

Performance Share Units

           During the three months ended March 31, 2022, we granted 327,939 performance share units ("PSUs") to certain key employees and officers as new awards under the 2020 Incentive Plan. Each PSU earned represents the right to receive either one share of common stock or, as determined by the administrator in its sole discretion, a cash amount equal to fair market value of one share of common stock or amount of cash on the day immediately preceding the settlement date. The actual number of shares of common stock that may be issued under the PSUs ranges from 0% up to a maximum of 200% of the target number of PSUs granted to the participant, based on our total shareholder return ("TSR") relative to a designated peer group, generally at the end of a three year period. In addition to the TSR conditions, vesting of the PSUs is generally subject to the

recipient’s continued employment through the end of the applicable performance period. Compensation expense is recorded ratably over the corresponding requisite service period. The grant date fair value of PSUs is determined using a Monte Carlo probability model. Grant recipients do not have any shareholder rights until performance relative to the peer group has been determined following the completion of the performance period and shares have been issued.

         In connection with a former officer’s separation agreement, on March 31, 2022, the Company modified the PSUs previously granted to such former officer in 2020 and 2021 to provide for deemed satisfaction of the service requirement applicable to such PSUs as of March 31, 2022, such that such PSUs shall remain outstanding and eligible to vest based on our TSR relative to a designated peer group over the applicable performance period. As a result of these modifications, we recorded an incremental stock expense of $3.7 million during the three months ended March 31, 2022.

 The following table summarizes information about PSUs activity during the three months ended March 31, 2022 (in thousands, except for weighted average fair value):

Period Granted	Target Shares Outstanding at January 1, 2022		Target Shares Granted		Target Shares Vested		Target Shares Forfeited		Target Shares Outstanding at March 31, 2022		Weighted Average Grant Date FV Per Share

           The Company rents five yards from an entity, in which certain former executive officers and a director of the Company have equity interests and the 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.

Pioneer

          On December 31, 2018, we consummated the purchase of certain pressure pumping assets and real property from Pioneer Natural Resources USA, Inc. ("Pioneer") and Pioneer Pumping Services (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. On March 31, 2022, we entered into an amended and restated pressure pumping services agreement (the "A&R Pressure Pumping Services Agreement"), which was initially entered into in connection with the Pioneer Pressure Pumping Acquisition. The A&R Pressure Pumping Services Agreement was effective January 1, 2022 and continues through December 31, 2022. The A&R Pressure Pumping Services Agreement reduced the number of contracted fleets to six fleets from eight fleets, modified the pressure pumping scope of work and pricing mechanism for contracted fleets, and replaced the idle fees arrangement with equipment reservation fees (the "Reservation fees"). As part of the Reservation fees arrangement, the Company will be entitled to receive compensation for all eligible contracted fleets that are made available to Pioneer at the beginning of every quarter in 2022 through the term of the A&R Pressure Pumping Services Agreement.

          Revenue from services provided to Pioneer (including idle fees and Reservation fees) accounted for approximately $123.5 million and $86.3 million of our total revenue during the three months ended March 31, 2022 and 2021, respectively.

          As of March 31, 2022, the total accounts receivable due from Pioneer, including estimated unbilled receivable for services we provided, amounted to approximately $79.3 million and the amount due to Pioneer was $0. As of December 31, 2021, the balance due from Pioneer for services we provided amounted to approximately $62.1 million and the amount due to Pioneer was $0.

 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. During the three months ended March 31, 2022 and 2021, the Company made lease payments of approximately $0.1 million and $0.1 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.

         We accounted for our Real Estate Lease as an operating lease. This conclusion 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 March 31, 2022, the weighted average discount rate and remaining lease term was approximately 6.7% and 1.0 year, respectively.

          As part of our expansion of our hydraulic fracturing equipment maintenance program, we entered into a two year maintenance facility real estate lease contract (the "Maintenance Facility Lease") with a commencement date of March 14, 2022. During the three months ended March 31, 2022, the Company made lease payments of approximately $0.03 million. In addition to the contractual lease period, the contract includes an optional renewal for three additional periods of one year each, 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 Maintenance Facility Lease does not contain variability in payments resulting from either an index change or rate change.

         We accounted for our Maintenance Facility Lease as 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 Maintenance Facility Lease because we concluded that the accounting effect was insignificant. As of March 31, 2022, the weighted average discount rate and remaining lease term was approximately 3.4% and 1.9 years, respectively.

          As of March 31, 2022, the total operating lease right-of-use asset cost was approximately $1.9 million, and accumulated amortization was approximately $0.9 million. As of December 31, 2021, our total operating lease right-of-use asset cost was approximately $1.2 million, and accumulated amortization was approximately $0.8 million. For the three months ended March 31, 2022 and 2021, we recorded operating lease cost of approximately $0.1 million and $0.1 million, respectively, in our statement of operations.

Maturity Analysis of Lease Liabilities

          The maturity analysis of liabilities and reconciliation to undiscounted and discounted remaining future lease payments for our operating lease as of March 31, 2022 are as follows:

($ in thousands)	Totals
2022	$	540
2023	398
2024	50
Total undiscounted future lease payments	988
Less: amount representing interest	(33)
Present value of future lease payments (lease obligation)	$	955

          The total cash paid for amounts included in the measurement of our operating lease liability during the three months ended March 31, 2022 was approximately $0.1 million. The non-cash lease obligation we recorded upon execution of the Maintenance Facility Lease was approximately $0.6 million. During the three months ended March 31, 2021, total cash paid for amounts included in the measurement of our operating lease liability was approximately $0.1 million.

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 three months ended March 31, 2022 and 2021 our short-term lease expense was approximately $0.2 million and $0.2 million, respectively.

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. At March 31, 2022, the total remaining lease commitments for all of our short-term leases and lodging commitments was approximately $3.1 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 minimum volumes or a fixed price per ton of unpurchased volumes. Our agreements with the Sand Suppliers expire at different times prior to December 31, 2025. During the three months ended March 31, 2022 and 2021, 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.

          As of March 31, 2022, the Company had issued letters of credit of approximately $4.2 million under the revolving credit facility in connection with the Company’s casualty insurance policy. Effective April 13, 2022, the Company's issued letters of credit increased to approximately $5.0 million 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 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 Exchange Act, 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, certain former officers and current and former directors. On September 13, 2021, the Court partially granted and partially denied the 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 their 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 a purported shareholder 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 Company's board of directors (the "Board") has constituted a committee to evaluate the demand letter and recommend a course of action to the Board, and the committee has retained counsel to assist with its review. The committee’s review is ongoing.

           We are presently unable to predict the duration, scope or result of the Logan Lawsuit, or any other related lawsuit or investigation. As of March 31, 2022, 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. No accrual was recorded in our financial statements in connection with this self-insurance strategy.

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 March 31, 2022, the audit is still ongoing and the final outcome cannot be reasonably estimated.

           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, excise and use tax for the audit period July 1, 2015 through December 31, 2018. The net refund to the Company of $10.7 million was recorded as part of other income in our statement of operations during the three months ended March 31, 2022. During the three months ended March 31, 2021, we recorded net refund of approximately $2.1 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation          The accompanying condensed consolidated financial statements of ProPetro Holding Corp. and its subsidiary (the "Company," "we," "us" or "our") have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission ("SEC") for interim financial information and do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for annual financial statements. Those adjustments (which consisted of normal recurring accruals) that are, in the opinion of management, necessary for a fair presentation of the results of the interim periods have been made. Results of operations for such interim periods are not necessarily indicative of the results of operations for a full year due to changes in market conditions and other factors. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2021, included in our Form 10-K filed with the SEC (our "Form 10-K").

Revenue Recognition

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 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 reservation or idle fee charges if a customer were to reserve or idle committed hydraulic fracturing equipment. The Company recognizes revenue related to idle or reservation fee charges on a daily basis or monthly 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 the 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 Receivable          Accounts receivables are stated at the amount billed and billable to customers.

Allowance for Credit Losses

Allowance for Credit Losses

          As of March 31, 2022, 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 the expected impact of any potential deteriorating economic conditions in the oil and gas industry. We evaluated the historic loss experience on our accounts receivable and also separately considered customers with receivable balances that could be negatively impacted by current 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.

Recently Issued Accounting Standards

Recently Issued Accounting StandardsRecently Issued Accounting Standards Adopted in 2022            In March 2020, the Financial Accounting Standards Board ("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. Effective January 1, 2022, we adopted this guidance, and the adoption did not materially affect the Company’s condensed consolidated financial statements.

Fair Value Measurement

Fair Value Measurement

           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.

          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 March 31, 2022 and December 31, 2021, approximated or equaled their carrying values as reflected in our condensed consolidated balance sheets.
