PROPETRO HOLDING CORP. AND SUBSIDIARY
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, 2016 included in the final prospectus of the Company filed with the SEC pursuant to rule 424(b) under the Securities Act of 1933 on March 20, 2017 ("Prospectus").

Initial Public Offering
          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 existing 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. Upon closing of the IPO, we used the proceeds (i) to repay $71.8 million in outstanding borrowings under our Term Loan (as defined in Note 4), (ii) to fund the purchase of additional hydraulic fracturing fleets and ancillary equipment, and (iii) for general corporate purposes.
          In connection with the IPO, the Company 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. Accordingly, any information related to, or dependent upon, the share or option counts in our comparative 2016 condensed consolidated financial statements (Unaudited) and Note 6, Net Income (Loss) per Share, Note 7, Stock-Based Compensation, and Note 10, Equity Capitalization, have been updated to reflect the effect of the stock split.

Note 2 - Recently Issued Accounting Standards
          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 originally effective for annual periods beginning after December 15, 2016, using either the retrospective or cumulative effect transition method. On August 12, 2015, the FASB issued ASU No. 2015-14, which defers the effective date of the revenue standard, ASU No. 2014-09, by one year for all entities and permits early adoption on a limited basis. We have completed our preliminary evaluation of ASU No. 2014-09, and the adoption of this guidance will not materially affect our revenue recognition. However, there will be additional disclosures on our consolidated financial statements relating to the adoption of this standard.
          In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. ASU No. 2015-11 does not apply to inventories that are measured by using either the last-in, first-out method or the retail inventory method. The amendments in ASU No. 2015-11 are effective for fiscal years beginning after December 15, 2016. The ASU became effective for us in 2017 and the adoption of this guidance did not materially affect our consolidated financial statements.
          In February 2016, the FASB issued ASU No. 2016-02, Leases, a new standard on accounting for leases. The ASU introduces a lessee model that brings most leases on the balance sheet. The new standard also aligns many of the underlying principles of the new lessor model with those in the current accounting guidance as well as the FASB’s new revenue recognition standard. 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 disclosures along with specific quantitative disclosures to better enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases.

(Unaudited)

Note 2 - Recently Issued Accounting Standards (Continued)


The new standard is effective for annual reporting periods beginning after December 15, 2018, including periods within that reporting period, using a modified retrospective approach. Early adoption is permitted. We have not completed an evaluation of the impact the pronouncement will have on our consolidated financial statements and related disclosures.
          In March 2016, the FASB issued ASU No. 2016-09, Compensation- Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which modifies several aspects of the accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new standard is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted. The ASU became effective for us in 2017 and the adoption of this guidance did not materially affect our consolidated financial statements.
          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.
Note 3 - Fair Value Measurements
          Fair value 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, and a derivative financial instrument. The estimated fair value of our financial instruments — cash and cash equivalents, accounts receivable and accounts payable at September 30, 2017 and December 31, 2016 approximates their carrying value as reflected in our condensed consolidated balance sheets due to their short-term nature. We use a derivative financial instrument, an interest rate swap, to manage interest rate risk. Our policies do not permit the use of derivative financial instruments for speculative purposes. We did not designate the interest rate swap as a hedge for accounting purposes. We record all derivatives as of the end of our reporting period in our condensed consolidated balance sheet at fair value, which is based on quoted market prices, a Level 1 input. We may be exposed to credit losses in the event of nonperformance by counterparties to the interest rate swap. The counterparty of the interest rate swap is a credible, large institution, and we do not believe there is significant or material credit risk upon settlement of the contract. The fair value of the interest rate swap liability at September 30, 2017 and December

Note 3 - Fair Value Measurement (Continued)

31, 2016 was $0.03 million and $0.3 million, respectively. Based on quoted market prices as of September 30, 2017 and 2016, for contracts with similar terms and maturity date, as provided by the counterparty, we recorded a gain of $0.2 million and $0.1 million during the nine months ended September 30, 2017 and 2016, respectively.

          No impairment of property and equipment was recorded during the nine months ended September 30, 2017 and 2016. During the fourth quarter of 2016, the depressed cash flows and continued decline in utilization of our Permian drilling assets were indicative of potential impairment, resulting in the Company comparing the carrying value of the Permian drilling assets with its estimated fair value. We determined that the carrying value of the Permian drilling assets was greater than its estimated fair value, and as such, an impairment expense was recorded in the fourth quarter of 2016. The non-cash asset impairment charges recorded in the fourth quarter of 2016 for Permian drilling was $6.3 million, which had a then net carrying value of $15.0 million prior to the impairment write-down.
          We generally apply fair value techniques to our reporting units on a nonrecurring basis associated with valuing potential impairment loss related to goodwill. Our estimate of the reporting unit fair value is based on a combination of income and market approaches, Level 1 and 3, respectively, in the fair value hierarchy. The income approach involves the use of a discounted cash flow method, with the cash flow projections discounted at an appropriate discount rate. The market approach involves the use of comparable public companies market multiples in estimating the fair value. Significant assumptions include projected revenue growth, capital expenditures, utilization, gross margins, discount rates, terminal growth rates, and weight allocation between income and market approaches. If the reporting unit's carrying amount exceeds its fair value, we consider goodwill impaired, and the impairment loss is calculated and recorded. There were no additions to, or disposal of, goodwill during the nine months ended September 30, 2017 and 2016. At December 31, 2016, we estimated the fair value of the surface drilling reporting unit to be $3.8 million and its carrying value was $4.2 million. As a result of the potential impairment due to the carrying value exceeding the estimated fair value, we then further determined the implied fair value of the $1.2 million goodwill for the surface drilling reporting unit to be $0. Accordingly, we recorded an impairment loss of $1.2 million during the fourth quarter of 2016.

Note 4 - Long-Term Debt
2013 Term Loan and Revolving Credit Facility
          On September 30, 2013, we entered into a term loan in the amount of $220 million ("Term Loan") with a $40 million revolving credit line ("Revolving Credit Facility"). Borrowings under the Term Loan and Revolving Credit Facility accrued interest at LIBOR plus 6.25%, subject to a 1% LIBOR floor, and were secured by a first priority lien and security interest in all assets of the Company. Proceeds from the Term Loan were used to pay off 100% of our debt outstanding, including accrued interest, at September 30, 2013, with excess proceeds from the Term Loan and the Revolving Credit Facility used to fund growth and working capital needs. The Term Loan and Revolving Credit Facility were scheduled to mature on September 30, 2019 and September 30, 2018, respectively, with quarterly and monthly payments of principal and interest, respectively.
          Under the Term Loan and Revolving Credit Facility we were 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 reporting, insurance, collateral maintenance, change of control, transactions with affiliates, distributions, and limitations on additional indebtedness. In addition, the Term Loan and Revolving Credit Facility included a maximum leverage ratio of 3.5x EBITDA (earnings before interest, taxes, depreciation, and amortization) to total debt, which became effective March 31, 2014.
          In 2015, given the then near-term economic uncertainty and volatility of commodity prices, we determined that we were likely to be out of compliance with the leverage ratio covenant under the Term Loan and Revolving Credit Facility at the March 31, 2016 test date. Accordingly, the Company and its equity sponsor, Energy Capital Partners ("ECP"), commenced negotiations with the lenders to amend the covenants and leverage ratio in the Term Loan and Revolving Credit Facility. The resulting amendment and waiver agreement was executed on June 8, 2016. Under the terms of the amendment, ECP infused $40 million of additional equity into the Company, $10 million of which was reserved for working capital, with up to $30 million available to repurchase debt. A minority shareholder also infused $0.425 million alongside ECP to prevent dilution. The amendment and waiver also suspended the leverage ratio test until June 30, 2017, and provided us with 30 days to deliver any past-due financial statements.
          Gain on Extinguishment of Debt — in connection with the amendment to the Term Loan and Revolving Credit Facility, we initiated an auction process with the lenders to repurchase a portion of debt for a price of 80 cents, a 20% discount to par value. The auction settled on June 16, 2016 as the Company repurchased a total amount of $37.5 million of debt for $30 million plus $0.5 million in debt extinguishment auction costs, leading to a gain on extinguishment of debt of $7.0 million.
          On January 13, 2017, we repaid $75 million of the outstanding balance under the Term Loan and repaid the remaining balance of $13.5 million under the Revolving Credit Facility using a portion of the proceeds from the private placement offering. On March 22, 2017, we retired the $71.8 million remaining balance of the Term Loan, along with accrued interest, using a portion of the proceeds from our IPO. Each of the Term Loan and Revolving Credit Facility were terminated in accordance with their terms upon the repayment of outstanding borrowings.
Equipment and Manufacturing Notes
          On November 24, 2015, we entered into a 36-month financing arrangement for three hydraulic fracturing fleets in the amount of $25 million, and a portion of the proceeds were used to pay off the previous manufacturer notes, with the remainder being used for additional liquidity.
          On June 30, 2017, we entered into a financing arrangement for the purchase of light vehicles. As of September 30, 2017, we purchased certain light vehicles under this financing arrangement in the amount of $2.1 million.

ABL Credit Facility
          On March 22, 2017, we entered into a new revolving credit facility with a $150 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 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.

Note 6 - Net Income (Loss) Per Share
          Net income (loss) per share is determined by dividing the net income (loss) relevant to the common stockholders by the weighted average number of shares outstanding during the period. Diluted net income (loss) per common share uses the same net income (loss) divided by the number of shares that would be outstanding assuming dilutive options and stock are converted.

Note 7 - Stock-Based Compensation

Stock Options

          Effective March 4, 2013, we adopted the ProPetro Stock Option Plan pursuant to which our Board of Directors may grant stock options or other stock-based awards to key employees, consultants, and directors. The Plan, as amended, is authorized to grant up to 4,645,884 shares of common stock to be issued upon exercise of the options. The Company’s share price used to estimate the fair value of the option at the grant date was based on a combination of income and market approaches, which are highly complex and sensitive. The income approach involves the use of a discounted cash flow method, with cash flow projections discounted at an appropriate discount rate. The market approach involves the use of comparable public companies market multiples in estimating the fair value of the Company’s stock. The expected term used to calculate the fair value of all options considers the vesting date and the grant’s expiration date. The expected volatility was estimated by considering comparable public companies, and the risk free rate is based on the U.S treasury yield curve as of the grant date. The dividend assumption is based on historical experience. After becoming a public company, the market price was used to determine the market value of our common stock. Prior to 2015, we had granted a total of 3,499,228 options with an exercise price of $3.96 per option, and all options expire 10 years from the date of grant.

Note 7 - Stock-Based Compensation (Continued)

          On June 14, 2013, we granted 2,799,408 stock option awards to certain key employees and directors that shall vest and become exercisable based upon the achievement of a service requirement. The options vest in 25% increments for each year of continuous service and an option becomes fully vested upon the optionee’s completion of the fourth year of service. The contractual term for the options awarded is 10 years. For the nine months ended September 30, 2017 and 2016, we recognized $0.7 million and $0.9 million, respectively, in compensation expense related to these stock options. The fair value of each option award granted is estimated on the date of grant using the Black-Scholes option-pricing model. The fair value of the options was estimated at the date of grant using the following assumptions:

          On December 1, 2013, we granted 699,820 stock option awards to certain key employees which were scheduled to vest in four substantially equal annual installments, subject to service and performance requirements and acceleration upon a change in control. As of September 30, 2016, the performance requirement was not considered to be probable of achievement for any of the outstanding option awards and 114,456 options were forfeited during the year ended December 31, 2016. Accordingly, we have not recognized any compensation expense related to these stock options as of September 30, 2016. Effective March 16, 2017, we terminated the options in connection with the IPO and approved a cash bonus totaling $5.1 million to the holders of the options.

          The contractual term for the options awarded is 10 years. The fair value of each option award granted is estimated on the date of grant using the Black-Scholes option-pricing model. The fair value of the options was estimated at the date of grant using the following assumptions:

The contractual term for the options awarded is 10 years. For the nine months ended September 30, 2017, we recognized the remaining $1.8 million in stock compensation expense related to these stock options, as the Company fully accelerated vesting of the options in connection with the IPO, and for the nine months ended September 30, 2016, we recognized $0.2 million in stock compensation expense related to these stock options.

          The fair value of each option award granted is estimated on the date of grant using the Black- Scholes option-pricing model. The fair value of the options was estimated at the date of grant using the following assumptions:

The IAP authorizes up to 5,800,000 shares of common stock to be issued under awards granted pursuant to the plan. On March 16, 2017, we granted 793,738 stock option awards to certain key employees and directors pursuant to the IAP which are scheduled to vest in four substantially equal annual installments, subject to a continuing service requirement. The contractual term for the options awarded is 10 years. For the nine months

Restricted Stock Units (Non-Vested Stock) and Performance Stock Units
    
          On September 30, 2013, our Board of Directors authorized and granted 372,335 restricted stock units (RSUs) to a key executive. Each RSU represents the right to receive one share of common stock of the Company at par value $0.001 per share. Under the terms of the award, the shares of common stock subject to the RSUs were to be paid to the grantee upon change in control, regardless of whether the grantee was affiliated with the Company on the settlement date. The fair value of the RSUs is measured as the price of the Company’s shares on the grant date, which was estimated to be $3.89. The share price used to estimate the fair value of the RSU at the grant date was based on a combination of income and market approaches, which are highly complex and sensitive. The income approach involves the use of a discounted cash flow method, with the cash flow projections discounted at an appropriate discount rate. The market approach involves the use of comparable public companies market multiples in estimating the fair value of the Company’s stock. Effective March 22, 2017, the Board of Directors canceled these RSUs and issued 372,335 new RSUs to the grantee. These issued RSUs are effectively identical to the RSUs granted in 2013, provided, however, that the RSUs will now be payable in full on March 22, 2018. The fair value of the RSUs

issued on March 22, 2017, was based on the Company's stock market price at the grant date. In connection with the IPO, we fully recognized the stock compensation expense related to the re-issued RSUs.

          On June 5, 2017, our Board of Directors granted 319,250 RSUs to employees, directors and executives pursuant to the IAP. Each RSU represents the right to receive one share of common stock. The fair value of the RSUs is based on the closing share price of our common stock on the date of grant. During the nine months ended September 30, 2017 and 2016, the recorded stock compensation expense for all RSUs was $5.8 million and $0, respectively.

           Effective June 5, 2017, our Board of Directors authorized and granted performance stock unit awards to certain key employees under the IAP. The actual number of shares that may be issued under the performance stock unit awards ranges from zero up to a maximum of twice the target number of performance stock unit awards granted to the participant, based on our total shareholder return relative to a designated peer group from the date of our IPO through December 31, 2019. Compensation expense is recorded ratably over the corresponding requisite service period. The fair value of performance stock unit awards 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. During the nine months ended September 30, 2017 and 2016 the recorded stock compensation expense for the performance stock units was $0.2 million and $0, respectively.

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 Prospectus 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 growth-oriented, 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 unconventional oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated long-standing customer relationships with some of the region's most active and well-capitalized E&P companies. The Permian Basin is widely regarded as the most prolific oil-producing area in the United States, and we believe we are currently one of the largest providers of hydraulic fracturing services in the region by hydraulic horsepower, or HHP, with a current aggregate deployed capacity of 690,000 HHP. Our fleet, which consists of 16 hydraulic fracturing fleets, has been designed to handle the highest intensity, most complex hydraulic fracturing jobs and has been 100% utilized since September 2016. During the third quarter ended September 30, 2017, we put three new hydraulic fracturing fleets into service. Subsequent to the end of this quarter, we also deployed one additional new hydraulic fracturing fleet in the fourth quarter of 2017, bringing our current total to 16, and aggregate capacity to 690,000 HHP. In addition, we have committed to acquire one new additional hydraulic fracturing fleet which is expected to be delivered before the end of the first quarter of 2018. This fleet will provide us with an incremental 45,000 HHP, bringing our aggregate capacity to 735,000 HHP by the end of the first quarter of 2018.

          Through our pressure pumping segment (which also includes cementing and acidizing operations), we primarily provide hydraulic fracturing services to E&P companies in the Permian Basin. Our modern hydraulic fracturing fleet has been designed to handle Permian Basin specific operating conditions and the region's increasingly high-intensity well completions, which are characterized by longer horizontal wellbores, more frac stages per lateral and increasing amounts of proppant per well. The majority of our fleet has been delivered in recent years, and we have fully maintained our equipment throughout the recent industry downturn to ensure optimal performance and reliability. Additionally, all of the hydraulic horsepower delivered over the last four years has been sourced from a single manufacturer, leading to a homogeneous fleet with streamlined maintenance programs and training for our personnel.

          In addition to our core pressure pumping segment operations, we also offer a suite of complementary well completion and production services, including coiled tubing, flowback, Permian drilling and surface air drilling. We believe these complementary services create operational efficiencies for our customers and allow us to capture a greater portion of their capital spending across the lifecycle of a well. Additionally, we believe that these complementary services should benefit from a continued industry recovery and that we are well positioned to continue expanding these offerings in response to our customers increasing service needs and spending levels.

Industry Trends and Outlook 
          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, 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. Declines and sustained weakness in crude oil prices began in the fourth quarter of 2014 and continued into February 2016, when the closing crude oil price reached a low of $26.19 per barrel. This decline in oil prices caused our customers to reduce drilling and completion activity and curtail spending. These declines adversely affected the demand for our equipment and services and negatively impacted the prices we were able to charge our customers.

          Most recently, the recovery of crude oil prices to a high in excess of $50 per barrel since December 2016 through September 2017, has driven a considerable increase in drilling and completion activity, and associated demand for our services. The Permian Basin, our primary area of operation, is leading the recovery with the number of active drilling rigs increasing

-18-

Table of Contents

from a low of 137 rigs in the basin as of May 2016 to 385 rigs in the basin as of September 2017, according to Baker Hughes. In addition to increased activity levels in the Permian Basin, several evolving industry trends, including increasingly longer horizontal wellbore laterals, a greater number of frac stages per lateral and increasing amounts of proppant employed per well, have significantly increased demand for our hydraulic fracturing and other completion services.
          As the Permian Basin shifts further towards more intensive horizontal drilling, operators and service providers are expected to continue to place significant focus on drilling and completion efficiencies, such as multi-well pads and zipper fracs. Multi-well pads allow for the drilling of multiple wellbores from a single topside location, reducing average drilling time. Similarly, zipper fracturing allows for the alternating completion of hydraulic fracturing stages in adjacent wells, increasing the number of stages that can be performed in a given time period. These advancements have resulted in a reduction in the number of days typically required to drill and complete a well and increased the total number of wells that can be drilled per rig, which, in turn, drives incremental demand for hydraulic fracturing services.
          Rising producer activity levels, increasing basin service intensity and continued drilling and completion efficiencies have combined to drive the 100% utilization of our fleet and build a sizable backlog of addressable demand for our services. During the recent downturn, we saw our competitors defer necessary maintenance capital spending and cannibalize existing units for spare parts and idle HHP. This has resulted in tightening hydraulic fracturing supply and demand fundamentals and could drive pricing improvement for our hydraulic fracturing services. Moreover, we believe the other complementary services we provide are well-positioned to similarly benefit from a continued industry recovery.
          Our competitors include many large and small oilfield services companies, including RPC, Inc., Halliburton, C&J Energy Services, Patterson-UTI Energy Inc., Superior Energy Services, Schlumberger and a number of private companies. Competitive factors impacting sales of our services are price, reputation and technical expertise, service and equipment quality, and health and safety standards. Although we believe our customers consider all of these factors, we believe price is a key factor in E&P companies' criteria in choosing a service provider. While we seek to price our services competitively, we believe many of our customers elect to work with us based on our deep local roots, operational expertise, the capability of our modern fleet to handle the most complex Permian Basin well completions, and commitment to safety and reliability.
          Our substantial market presence in the Permian Basin positions us well to capitalize on increasing drilling and completion activity in the region. Historically, our operational focus has been in the Permian Basin's Midland sub-basin, where our customers have primarily operated. More recently however, with increasing levels of Delaware Basin activity, we have recently expanded our presence in the Delaware Basin in response to increasing levels of demand pull from our customers. Given our entrenched relationships with a variety of Delaware Basin operators, we believe that we are uniquely positioned to capture large addressable growth opportunity as the basin develops. 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.
     
How We Evaluate Our Operations 
          Our management uses a variety of financial and operating metrics to evaluate and analyze the performance of our business, including Adjusted EBITDA and Adjusted EBITDA margin.

EBITDA, Adjusted EBITDA and Adjusted EBITDA margin
          We view Adjusted EBITDA and Adjusted EBITDA margin as important indicators of performance. We define EBITDA as our net income (loss), 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) (gain) on extinguishment of debt, (iii) stock based compensation, and (iv) other unusual or nonrecurring expenses, such as impairment charges and costs related to our initial public offering. 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, research analysts and others, 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 expenses (such as IPO bonus) and items outside the control of our management team (such as income tax rates). Adjusted EBITDA and Adjusted EBITDA margin have limitations as analytical tools and should not be considered as an alternative to net income, operating income, 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. We believe that the presentation of these non-GAAP financial measures 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 and items outside the control of the Company. Net income is the GAAP measure most directly comparable to Adjusted EBITDA. Our non-GAAP financial measures 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 conduct our business through seven operating segments: hydraulic fracturing, cementing, acidizing, coil tubing, flowback, surface drilling, and Permian drilling. For reporting purposes, the hydraulic fracturing, cementing and acidizing operating segments are aggregated into our one reportable segment—pressure pumping. All other operating segments and corporate administrative expenses are included in the ‘‘all other’’category. We expect revenues and costs of services related to our Permian drilling operating segment to comprise a lower percentage of total revenues and total costs of service in future results of operations when compared to historic results due to our increased focus on pressure pumping and other complementary service offerings. We anticipate the financial significance of this service line relative to the financial results from pressure pumping and other service offerings to continue to decline.

THREE MONTHS ENDED SEPTEMBER 30, 2017 COMPARED TO THREE MONTHS ENDED SEPTEMBER 30, 2016


          Revenues.    Revenues increased 141.8%, or $165.8 million, to $282.7 million for the three months ended September 30, 2017, as compared to $116.9 million for the three months ended September 30, 2016. The increase was primarily attributable to the increase in customer activity, fleet size and demand for our services, which has led to an increase in pricing for our hydraulic fracturing and other services. Our pressure pumping segment revenues increased 147.9%, or $162.2 million, for the three months ended September 30, 2017, as compared to the three months ended September 30, 2016. Revenues from services other than pressure pumping increased 49.9%, or $3.6 million, for the three months ended September 30, 2017 as compared to the three months ended September 30, 2016. The increase in revenues from services other than pressure pumping was primarily attributable to the increase in revenues and customer demand for our flowback, coil tubing and surface drilling services, offset by the decrease in revenue from the idling of our Permian drilling rigs in the three months ended September 30, 2017.
          Cost of Services.    Cost of services increased 104.5%, or $115.2 million, to $225.4 million for the three months ended September 30, 2017, from $110.2 million during the three months ended September 30, 2016. Cost of services in our pressure pumping segment increased $113.7 million for the three months ended September 30, 2017, as compared to the three months ended September 30, 2016. The increases were primarily attributable to higher activity levels, fleet size, coupled with an increase in personnel headcount following the increased activity levels. As a percentage of pressure pumping segment revenues, pressure pumping cost of services decreased to 79.9% for the three months ended September 30, 2017, as compared to 94.3% for the three months ended September 30, 2016. The decrease in cost of services as a percentage of revenue for the pressure pumping segment resulted from a greater pricing power as demand for our services increased, without a corresponding increase in costs, which resulted in significantly higher realized Adjusted EBITDA margins during the three months ended September 30, 2017.
          General and Administrative Expenses.    General and administrative expenses increased 89.7%, or $5.3 million, to $11.1 million for the three months ended September 30, 2017, as compared to $5.9 million for the three months ended September 30, 2016. The increase was primarily attributable to increases in legal and professional fees, insurance expense and payroll, totaling $4.5 million, and a net increase in other remaining general and administrative expenses totaling $0.7 million.
          Depreciation and Amortization.    Depreciation and amortization increased 36.7%, or $4.0 million, to $14.7 million for the three months ended September 30, 2017, as compared to $10.8 million for the three months ended September 30, 2016. The increase was primarily attributable to additional property and equipment purchased in 2017. We calculate depreciation of property and equipment using the straight-line method.
          Loss on Disposal of Assets.    Loss on the disposal of assets increased 47.6%, or $2.8 million, to $8.7 million for the three months ended September 30, 2017, as compared to $5.9 million for the three months ended September 30, 2016. The increase was primarily attributable to greater service intensity of jobs completed coupled with higher fleet size, activity levels and utilization of our equipment.
          Interest Expense.    Interest expense decreased 85.8%, or $3.9 million, to $0.6 million for the three months ended September 30, 2017, as compared to $4.6 million for the three months ended September 30, 2016. The decrease in interest expense was primarily attributable to a reduction in our average debt balance during 2017 due to the early retirement of our Term Loan and Revolving Credit Facility in the first quarter of 2017.
          Other Expense.    Other expense was $0.2 million for the three months ended September 30, 2017, as compared to other expense of $0.1 million for the three months ended September 30, 2016. The marginal net increase was primarily attributable to decrease in the unrealized gain resulting from the change in the fair value of our interest rate swap liability at September 30, 2017 compared to September 30, 2016, and partially offset by a decrease in other lender related expenses.
          Income Tax Expense/(Benefit).    For the three months ended September 30, 2017, we utilized the discrete effective tax rate method as allowed by Accounting Standards Codification (“ASC”) 740-270-30-18, Income Taxes - Interim Reporting to calculate its interim tax provision. The discrete method treats the year to date period as if it was the annual period and determines the income tax expense or benefit on that basis. We believe that, at this time, the use of this discrete method is more appropriate than the annual effective tax rate method as the annual effective tax rate is not reliable because small changes in estimated “ordinary” income would result in significant changes in the estimated annual effective tax rate. Total income tax benefit was $0.1 million resulting in a negative effective tax rate of 0.4% for the three months ended September 30, 2017 as compared to total income tax benefit of $6.9 million and an effective tax rate of 33.8% for the three months ended September 30, 2016. The negative effective tax rate is primarily due to our full valuation allowance position, impact of indefinite lived assets, state tax expense and alternative minimum tax expense, which creates a deviation from the customary relationship between income tax expense (benefit) and pre-tax income/(loss).

NINE MONTHS ENDED SEPTEMBER 30, 2017 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30, 2016

          Revenues.    Revenues increased 144.7%, or $395.2 million, to $668.2 million for the nine months ended September 30, 2017, as compared to $273.0 million for the nine months ended September 30, 2016. The increase was primarily attributable to the increase in customer activity, fleet size and demand for our services, which has led to an increase in pricing for our hydraulic fracturing and other services. Our pressure pumping segment revenues increased 154.3%, or $387.9 million for the nine months ended September 30, 2017 as compared to the nine months ended September 30, 2016. Revenues from services other than pressure pumping increased 33.4%, or $7.2 million, in the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016. The increase in revenues from services other than pressure pumping during the nine months ended September 30, 2017 was primarily attributable to the increase in revenues and customer demand for our flowback, coil tubing and surface drilling services, offset by the decrease in revenue from idling of our Permian drilling rigs.
          Cost of Services.    Cost of services increased 116.1%, or $296.4 million, to $551.8 million for the nine months ended September 30, 2017, from $255.4 million during the nine months ended September 30, 2016. Cost of services in our pressure pumping segment increased $294.2 million for the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016. The increases were primarily attributable to higher activity levels, coupled with an increase in personnel headcount following the increased activity levels. As a percentage of pressure pumping segment revenues, pressure pumping cost of services decreased to 82.9% for the nine months ended September 30, 2017, as compared to 93.7% for the nine months ended September 30, 2016. The decrease in cost of services as a percentage of revenue for the pressure pumping segment resulted from greater pricing power as demand for our services increased, without a corresponding increase in costs, which resulted in significantly higher realized Adjusted EBITDA margins during the nine months ended September 30, 2017.
          General and Administrative Expenses.    General and administrative expenses increased 126.1%, or $21.7 million, to $38.9 million for the nine months ended September 30, 2017, as compared to $17.2 million for the nine months ended September 30, 2016. The increase was primarily attributable to increases in legal and professional fees, insurance expense and payroll, totaling $6.7 million, IPO bonus of $7.7 million to key employees, along with $7.6 million increase in stock compensation recorded during 2017, and partially offset by a $0.3 million decrease in other remaining general and administrative expenses. General and administrative expenses, excluding non-recurring deferred IPO bonus of $7.7 million and stock compensation compensation expense of $6.8 million, as a percentage of total revenues decreased to 3.6% for the nine months ended September 30, 2017, as compared to 6.3% for the nine months ended September 30, 2016, and the decrease is as a result of the higher revenue in the nine months ended September 30, 2017.
          Depreciation and Amortization.    Depreciation and amortization increased 18.2%, or $5.9 million, to $38.6 million for the nine months ended September 30, 2017, as compared to $32.7 million for the nine months ended September 30, 2016. The increase was primarily attributable to additional property and equipment purchased and put into service during the nine months ended September 30, 2017. We calculate depreciation of property and equipment using the straight-line method.
