          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, 2017 included in our Form 10-K filed with the SEC ("Form 10-K").

          Pressure Pumping — Pressure pumping consists of downhole pumping services, which includes hydraulic fracturing (inclusive of acidizing services) and cementing.

           All Other— All other services consist of our surface air drilling, drilling, coil tubing and flowback, which are all downhole well simulation and completion/remedial services. The performance obligation for each of the 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 receivables are stated at the amount billed and billable to customers. At June 30, 2018 and December 31, 2017, accrued revenue (unbilled receivable) included as part of our accounts receivable was $43.4 million and $24.8 million, respectively. At June 30, 2018, the transaction price allocated to the remaining performance obligation for our partially completed hydraulic fracturing operations was $36.9 million, which is expected to be completed and recognized in the two months following the current period balance sheet date, in our pressure pumping reportable segment.

          On March 22, 2017, we consummated our initial public offering ("IPO"), in which 25,000,000 shares of our common stock, par value $0.001 per share, were sold at a public offering price of $14.00 per share, with 13,250,000 shares issued and sold by the Company and 11,750,000 shares sold by selling stockholders. We received net proceeds of approximately $170.1 million after deducting $10.9 million of underwriting discounts and commissions, and $4.5 million of other offering expenses. At closing, we used the proceeds (i) to repay $71.8 million in outstanding borrowings under our term loan, (ii) $86.8 million to fund the purchase of additional hydraulic fracturing units and other equipment, and (iii) the remaining for general corporate purposes. In connection with the IPO, we executed a stock split, such that each holder of common stock of the Company received 1.45 shares of common stock for every one share of previous common stock, and all 16,999,990 shares of our previously outstanding Series A preferred stock converted to common stock on a 1:1 basis.

          In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 requires entities to recognize revenue to depict transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU No. 2014-09 requires entities to disclose both qualitative and quantitative information that enables users of the consolidated financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including disclosure of significant judgments affecting the recognition of revenue. ASU No. 2014-09 was effective for annual periods beginning after December 15, 2017, using either the full retrospective or modified retrospective method. We adopted ASU No. 2014-09 effective January 1, 2018, using the modified retrospective method. The adoption of this guidance had a nil impact on our prior period consolidated financial statements. This is because prior to the effective date of the new revenue guidance, substantially all of our performance obligations per our contracts with customers, except for hydraulic fracturing, were completed at a point-in-time and revenue recognized when control was transferred to the customers, which is consistent with ASU No. 2014-09. Our hydraulic fracturing segment performance obligation is satisfied over time. Prior to the effective date of the new revenue standards, our hydraulic fracturing segment revenue was recognized based on actual stages completed, i.e. using the output method, which faithfully depicts how our services are transferred over time to our customers, and is consistent with the requirements of the new guidance, ASU No. 2014-09. Accordingly, no adjustments to our consolidated financial statements were required, other than the additional disclosures included as part of Note 1 in these condensed consolidated financial statements.

                 In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU introduces a lessee model that brings most leases on the balance sheet. This new standard increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from leases by recording them on the balance sheet as Right of Use ("ROU") Assets and Lease Liabilities. Leases will be classified as either finance or operating, which will impact the pattern of expense recognition on the income statement. However, the ASU eliminates the use of bright-line tests in determining lease classification as required in the current guidance. The ASU also requires additional qualitative and quantitative disclosures to better enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. This ASU is effective for annual reporting periods beginning after December 15, 2018, using a modified retrospective approach. Early adoption is permitted. We are in the process of finalizing the impact this guidance will have on our consolidated financial statements. Per our analysis thus far, we do not expect this new guidance to have a material impact on our consolidated financial statements. However, we will record the balance sheet impact associated with ROU assets and lease liabilities on our leases. Additionally, we intend to adopt the modified retrospective approach with an election to implement the guidance only in our 2019 consolidated financial statements, which is the year it becomes effective for us.

                    In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step two of the goodwill impairment test. As a result, under this ASU, an entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This pronouncement is effective for impairment tests in fiscal years beginning after December 15, 2019, on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We believe that the adoption of this guidance will not materially affect our consolidated financial statements.

          Our financial instruments include cash and cash equivalents, accounts receivable and accounts payable. The estimated fair value of our financial instruments — cash and cash equivalents, accounts receivable and accounts payable at June 30, 2018 and December 31, 2017 approximates their carrying value as reflected in our condensed consolidated balance sheets due to their short-term nature.

          Assets measured at fair value on a nonrecurring basis at June 30, 2018 and December 31, 2017, respectively, are set forth below:

          No impairment of property and equipment was recorded during the six months ended June 30, 2018 and 2017.

The market approach involves the use of comparable public companies market multiples in estimating the fair value. Significant assumptions include projected revenue growth, capital expenditures, utilization, gross margins, discount rates, terminal growth rates, and weight allocation between income and market approaches. If the reporting unit's carrying amount exceeds its fair value, we consider goodwill impaired, and the impairment loss is calculated and recorded. There were no additions to, or disposal of, goodwill during the six months ended June 30, 2018 and 2017. At December 31, 2017, we determined our goodwill balance not to be impaired as per our annual impairment test.

          On March 22, 2017, we entered into a new revolving credit facility with a $150.0 million borrowing capacity ("ABL Credit Facility"). Borrowings under the ABL Credit Facility accrue interest based on a three-tier pricing grid tied to availability, and we may elect for loans to be based on either LIBOR or base rate, plus the applicable margin, which ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans, with no LIBOR floor. Borrowings under the ABL Credit Facility are secured by a first priority lien and security interest in substantially all assets of the Company. The ABL Credit Facility has a tenor of 5 years and a borrowing base of 85% of eligible accounts receivable less customary reserves. 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. In addition, the ABL Credit Facility includes a Springing Fixed Charge Coverage Ratio of 1.0x when excess availability is less than the greater of (i) 10% of the lesser of the facility size and the Borrowing Base and (ii) $12.0 million. The ABL has a commitment fee of 0.375%, which reduces to 0.25% if utilization is greater than 50% of the borrowing base.

          On February 22, 2018, we entered into an amendment with our lenders to increase the capacity of the ABL Credit Facility. The amendment increased total capacity under the facility from $150.0 million to $200.0 million. The amended ABL Credit Facility includes a Springing Fixed Charge Coverage Ratio of 1.0x when excess availability is less than the greater of (i) 10% of the lesser of the facility size and the Borrowing Base and (ii) $15 million.

          Total debt consisted of the following at June 30, 2018 and December 31, 2017, respectively:

Annual Maturities — Scheduled remaining annual maturities of total debt are as follows at June 30, 2018:

          The Company has six operating segments for which discreet financial information is readily available: hydraulic fracturing (inclusive of acidizing), cementing, coil tubing, flowback, surface drilling, and drilling. These segments represent how the Chief Operating Decision Maker (CODM) evaluates performance and allocates resources. During the fourth quarter of 2017, our acidizing operation was consolidated into our hydraulic fracturing operating segment, and we no longer maintain discreet financial information for acidizing, resulting in a reduction in the number of our operating segments from seven previously reported in 2017 to six operating segments. The change in the number of our operating segments did not impact our reportable segment information reported during the three and six months ended June 30, 2018 and 2017.

          In accordance with Accounting Standards Codification 280—Segment Reporting, the Company has one reportable segment (pressure pumping) comprised of the hydraulic fracturing and cementing operating segments. All other operating segments and corporate administrative expenses are included in the ‘‘all other’’ category in the table below. 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, taxes, depreciation & amortization, stock-based compensation expense, impairment expense, (gain)/loss on disposal of assets and other unusual or nonrecurring expenses or income). A reconciliation from segment level financial information to the consolidated statement of operations is provided in the table below.
