LIBERTY OILFIELD SERVICES INC.
Notes to Condensed Consolidated and Combined Financial Statements
(Unaudited)


Note 1—Organization and Basis of Presentation
Organization
Liberty Oilfield Services Inc. (the “Company”) was incorporated as a Delaware corporation on December 21, 2016, to become a holding corporation for Liberty Oilfield Services New HoldCo LLC (“Liberty LLC”) and its subsidiaries upon completion of a corporate reorganization (as detailed below, the “Corporate Reorganization”) and planned initial public offering of the Company (“IPO”). The Company has no material assets other than its ownership in Liberty LLC.
Prior to the Corporate Reorganization, Liberty Oilfield Services Holdings LLC (“Liberty Holdings”) wholly owned Liberty Oilfield Services LLC (“LOS”) and LOS Acquisition CO I LLC (“ACQI” and, together with LOS, the “Predecessor”), which includes the assets and liabilities of LOS Odessa RE Investments, LLC (“Odessa”) and LOS Cibolo RE Investments, LLC (“Cibolo”). Following the Corporate Reorganization, Liberty LLC wholly owns the Predecessor. Effective March 22, 2018 the assets of ACQI were contributed into LOS and ACQI was dissolved.
The Company, together with its subsidiaries, is a multi-basin provider of hydraulic fracturing services, with a focus on deploying the latest technologies in the technically demanding oil and gas reservoirs in which it operates, principally in North Dakota, Colorado, Wyoming and Texas.
Corporate Reorganization
In connection with the IPO, the Company completed a series of organizational transactions, including the following:

•
Liberty Holdings contributed all of its assets to Liberty LLC in exchange for Liberty LLC Units (as defined below);

•
Liberty Holdings liquidated and distributed to its then-existing owners (the “Legacy Owners”) Liberty LLC Units pursuant to the terms of the limited liability company agreement of Liberty Holdings and the Master Reorganization Agreement dated as of January 11, 2018, by and among the Company, Liberty Holdings, Liberty LLC, and the other parties named therein (the “Master Reorganization Agreement”);

•
Certain of the Legacy Owners directly or indirectly contributed all or a portion of their Liberty LLC Units to the Company in exchange for 55,685,027 shares of our Class A common stock, par value $0.01 per share (the “Class A Common Stock”), and 1,258,514 restricted shares of Class A Common Stock. Subsequent to the initial exchange, 1,609,122 shares of Class A Common Stock were redeemed for an aggregate price of $25.9 million , upon the exercise of the underwriters’ overallotment option;

•
the Company issued, at par, the Legacy Owners that continued to own Liberty LLC Units (the “Liberty Unit Holders”) an aggregate amount of 48,207,372 shares of our Class B common stock, par value $0.01 per share (the “Class B Common Stock”); and

•
the Company contributed the net proceeds it received from the IPO to Liberty LLC in exchange for additional Liberty LLC Units such that the Company holds a total number of Liberty LLC Units equal to the number of shares of Class A Common Stock outstanding following the IPO.
Initial Public Offering
On January 17, 2018 the Company completed its IPO of 14,640,755 shares of its Class A Common Stock at a public offering price of $17.00 per share, of which 14,340,214 shares were offered by the Company and 300,541 were offered by the selling shareholder. The Company received $220.3 million net proceeds from the IPO, after deducting approximately $13.4 million in underwriting discounts and commissions and $10.1 million of other offering costs. The Company did not receive any proceeds from the sale of the shares of Class A Common Stock by the selling shareholder. The Company used $25.9 million of net proceeds to redeem ownership interests in Liberty LLC from the Legacy Owners. The Company contributed the remaining net proceeds to Liberty LLC in exchange for units in Liberty LLC (the “Liberty LLC Units”). Liberty LLC used a portion of these net proceeds (i) to repay outstanding borrowings and accrued interest under the Predecessor’s ABL Facility (as defined herein), totaling approximately $30.1 million , (ii) to repay 35% of the Predecessor’s outstanding borrowings, accrued interest and prepayment premium under the Term Loan Facility (as defined herein), totaling approximately $62.5 million and (iii) for

general corporate purposes, including repayment of additional indebtedness and funding a portion of 2018 and other future capital expenditures. As of June 30, 2018 , the Company owns 59.2% of Liberty LLC.
Basis of Presentation
The accompanying unaudited condensed consolidated and combined financial statements were prepared using generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these financial statements do not include all information or notes required by generally accepted accounting principles for annual financial statements and should be read together with the annual financial statements included in the 2017 Annual Report on Form 10-K.
The accompanying unaudited condensed consolidated and combined financial statements and related notes present the consolidated financial position, results of operations, cash flows, and equity of the Company as of and for the three and six months ended June 30, 2018 and the combined financial position, results of operations, and cash flows of the Predecessor as of December 31, 2017 and for the three and six months ended June 30, 2017 . The interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim period. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results of operations expected for the entire fiscal year ended December 31, 2018 .
All intercompany amounts have been eliminated in the presentation of these unaudited condensed consolidated and combined financial statements. Comprehensive income is not reported due to the absence of items of other comprehensive income or loss during the periods presented. The condensed consolidated and combined financial statements include financial data at historical cost as the contribution of assets is considered to be a reorganization of entities under common control. The condensed consolidated and combined financial statements may not be indicative of the actual level of assets, liabilities and costs that would have been incurred by the Predecessor if it had operated as an independent, publicly-traded company during the periods prior to the IPO or of the costs expected to be incurred in the future. In the opinion of management, the adjustments necessary for a fair presentation of the combined financial statements in accordance with GAAP have been made. Such adjustments are of a normal recurring nature.
The unaudited condensed consolidated and combined financial statements for periods prior to January 17, 2018, reflect the historical results of Predecessor. The unaudited condensed consolidated financial statements include the amounts of the Company and all majority owned subsidiaries where the Company has the ability to exercise control.
Note 2—Significant Accounting Policies
Revenue Recognition
Effective January 1, 2018, the Company adopted a comprehensive new revenue recognition standard, Accounting Standard Codification (“ASC”) Topic 606- Revenue from Contracts with Customers . The details of the significant changes to accounting policies resulting from the adoption of the new standard are set out below. The Company adopted the standard using a modified retrospective method; accordingly, the comparative information for the three and six months ended June 30, 2017 has not been adjusted and continues to be reported under the previous revenue standard. The adoption of this standard did not have a material impact to the condensed consolidated financial position, reported revenue, results of operations or cash flows as of and for the three and six months ended June 30, 2018 .
Under the new standard, revenue recognition is based on the transfer of control, or our customer’s ability to benefit from our services and products in an amount that reflects the consideration expected to be received in exchange for those services and products. In recognizing revenue for services and products, the transaction price is determined from sales orders or contracts with customers. Revenue is recognized at the completion of each fracturing stage, and in most cases the price at the end of each stage is fixed, however, in limited circumstances contracts may contain variable consideration.
Variable consideration typically may relate to discounts, price concessions and incentives. We estimate variable consideration based on the amount of consideration we expect to receive. The Company accrues revenue on an ongoing basis to reflect updated information for variable consideration as performance obligations are met.
The Company also assesses customers’ ability and intention to pay, which is based on a variety of factors including historical payment experience and financial condition. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 45 days.
From time to time, the Company may require partial payment in advance from new customers to secure credit or from existing customers in order to secure additional hydraulic fracturing services. Initially, such payments are recorded in the

accompanying condensed consolidated and combined financial statements as deferred revenue, and upon performance of the agreed services, the Company recognizes revenue consistent with its revenue recognition policy described above. As of June 30, 2018 , the Company had $3.8 million recorded as deferred revenue related to the unearned portion of a prepayment from an existing customer to secure additional services from a new fleet by the end of 2017. The new fleet commenced services in December 2017, and the Company applies the prepayment in accordance with the customer agreement as services are performed. During the three and six months ended June 30, 2018 , the Company recognized $2.9 million and $5.4 million of the prepayment to revenue, respectively.
Fleet Start-up Costs
The Company incurs start-up costs to commission a new fleet or district. These costs include hiring and training of personnel, and acquisition of consumable parts and tools. Start-up costs are expensed as incurred, and are reflected in general and administrative expenses in the combined statement of operations. Start-up costs for the three and six months ended June 30, 2018 were $3.3 million and $6.6 million , respectively, related to one and three new fleets deployed during each respective period. Start-up costs for the three and six months ended June 30, 2017 were $4.3 million and $8.9 million , respectively, related to four and six new fleets deployed during each respective period. The total amount of start-up costs incurred for the commissioning of each new fleet depends primarily on the number and timing of hiring additional personnel to staff such fleets, and such costs may not be entirely incurred in the same period as the fleet is deployed.
The terms and conditions of the Credit Facilities, defined herein, between the Company and its lenders provides for the add-back of costs or expenses incurred in connection with the acquisition, deployment and opening of any new hydraulic fracturing fleet or district in the computation of certain financial covenants. (See Note 5).
Recently Adopted Accounting Standards
In May 2014 the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This ASU sets forth a five-step model for determining when and how revenue is recognized. Under the model, an entity is required to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. Additional disclosures are required to describe the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The Company adopted this standard on January 1, 2018 using the modified retrospective method. The Company did not record a cumulative effect adjustment to the opening balance of retained earnings, as no adjustment was necessary. The adoption of this standard did not impact the Company’s reported revenue, net income or cash flows.
In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The adoption of ASU 2016-01 did not have a material impact on the condensed consolidated and combined financial statements of the Company.
In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides guidance on eight different issues, intended to reduce diversity in practice on how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The adoption of ASU 2016-15 did not have a material impact on the condensed consolidated and combined financial statements of the Company.
In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory,” which requires entities to recognize the tax consequences of intercompany asset transfers in the period in which the transfer takes place, with the exception of inventory transfers. The adoption of ASU 2016-16 did not have a material impact on the condensed consolidated and combined financial statements of the Company.
In May 2017, the FASB issued ASU No. 2017-09, “Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), which provides guidance to increase clarity and reduce both diversity in practice and cost and complexity when applying the existing accounting guidance on changes to the terms or conditions of a share-based payment award. The amendments in ASU 2017-09 require an entity to account for the effects of a modification unless all the following conditions are met: (i) the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; (ii) the vesting conditions of the modified award are the same as the vesting

7

LIBERTY OILFIELD SERVICES INC.
Notes to Condensed Consolidated and Combined Financial Statements
(Unaudited)

conditions of the original award immediately before the original award is modified; and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The guidance in ASU 2017-09 is applied prospectively. The amendments in ASU 2017-09 are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Company’s adoption of this guidance did not materially impact its condensed consolidated and combined financial statements.
Recently Issued Accounting Standards
In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a purchase financed by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less may be accounted for similarly to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 is expected to impact the Company’s consolidated and combined financial statements as the Company has certain operating and real property lease arrangements for which it is the lessee. The standard is effective on January 1, 2019, with early adoption permitted. The Company is currently evaluating the impact the adoption of this standard will have on its condensed consolidated and combined financial statements.
In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which is effective for fiscal years and interim periods within fiscal years beginning after December 15, 2019, with a modified-retrospective approach to be used for implementation. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. Specifically, this new guidance requires using a forward looking, expected loss model for trade and other receivables, held-to-maturity debt securities, loans and other instruments. This will replace the currently used model and may result in an earlier recognition of allowance for losses. The Company is currently evaluating the impact the adoption of this standard will have on its condensed consolidated and combined financial statements.

On September 19, 2017, the Company entered into two new credit agreements for a revolving line of credit up to $250.0 million (the “ABL Facility”) and a $175.0 million term loan (the “Term Loan Facility”, and together with the ABL Facility the “Credit Facilities”). Following is a description of the ABL Facility and the Term Loan Facility.
ABL Facility
Under the terms of the ABL Facility, up to $250.0 million may be borrowed, subject to certain borrowing base limitations based on a percentage of eligible accounts receivable and inventory. As of June 30, 2018 , the borrowing base was calculated to be $235.4 million , and the Company had no borrowings outstanding, except for a letter of credit in the amount of $0.3 million , with $235.1 million of remaining availability. Borrowings under the ABL Facility bear interest at LIBOR or a base rate, plus an applicable LIBOR margin of 1.5% to 2.0% or base rate margin of 0.5% to 1.0% , as defined in the ABL Facility credit agreement. The unused commitment is subject to an unused commitment fee of 0.375% to 0.5% . Interest and fees are payable in arrears at the end of each month, or, in the case of LIBOR loans, at the end of each interest period. The ABL Facility matures on the earlier of (i) September 19, 2022 and (ii) to the extent the debt under the Term Loan Facility remains outstanding, 90 days prior to the final maturity of the Term Loan Facility, which matures on September 19, 2022. Borrowings under the ABL

(Unaudited)

Facility are collateralized by accounts receivable and inventory, and further secured by the Company, Liberty LLC and R/C IV Non-U.S. LOS Corp., a Delaware corporation and a subsidiary of the Company, as parent guarantors.
Term Loan Facility
The Term Loan Facility provides for a $175.0 million term loan, of which $113.0 million remained outstanding as of June 30, 2018 . Amounts outstanding bear interest at LIBOR or a base rate, plus an applicable margin of 7.625% or 6.625% , respectively, and the weighted average rate on borrowings was 9.7% as of June 30, 2018 . The Company is required to make quarterly principal payments of 1% per annum of the initial principal balance, commencing on December 31, 2017, with final payment due at maturity on September 19, 2022. The Term Loan Facility is collateralized by the fixed assets of LOS and its subsidiaries, and is further secured by the Company, Liberty LLC and R/C IV Non-U.S. LOS Corp., a Delaware corporation and a subsidiary of the Company, as parent guarantors.
The Credit Facilities include certain non-financial covenants, including but not limited to restrictions on incurring additional debt and certain distributions. Moreover, the ability of the Company to incur additional debt and to make distributions is dependent on maintaining a maximum leverage ratio. The Term Loan Facility requires mandatory prepayments upon certain dispositions of property or issuance of other indebtedness, as defined, and annually a percentage of excess cash flow ( 25% to 50% , depending on leverage ratio, of consolidated net income less capital expenditures and other permitted payments, commencing with the year ending December 31, 2018). Certain mandatory prepayments and optional prepayments are subject to a prepayment premium of 3% of the prepaid principal declining annually to 1% during the first three years of the term of the Term Loan Facility.
The Credit Facilities are not subject to financial covenants unless liquidity, as defined in the respective credit agreements, drops below a specified level. Under the ABL Facility, the Company is required to maintain a minimum fixed charge coverage ratio, as defined in the credit agreement governing the ABL Credit Facility, of 1.0 to 1.0 for each period if excess availability is less than 10% of the borrowing base or $12.5 million , whichever is greater. Under the Term Loan Facility, the Company is required to maintain a minimum fixed charge coverage ratio, as defined, of 1.2 to 1.0 for each trailing twelve-month period if the Company’s liquidity, as defined, is less than $25.0 million for at least five consecutive business days.
The Company was in compliance with these covenants as of June 30, 2018 .

Note 6—Redeemable Common Units
During February 2017, ACQI received $39.8 million in cash from Liberty Holdings in exchange for 40,000,000 redeemable common units of ACQI which accrue a return of 8% per annum (the “Redeemable Common Units”). The Redeemable Common Units were redeemable at the option of the holder on the later of (A) the earlier of an initial public offering or March 23, 2020 and (B) the second business day after all principal and interest outstanding under the ABL Facility have been paid in full and commitments thereunder are terminated. In accordance with ASC 505, “Equity”, due to their conditional redemption feature, the Redeemable Common Units were classified as temporary equity in the accompanying combined balance sheet as of December 31, 2017 .
The Redeemable Common Units were deemed extinguished and satisfied in full in connection with the Corporate Reorganization (see Note 1).
Note 7—Fair Value Measurements and Financial Instruments
The fair values of the Company’s assets and liabilities represent the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction at the reporting date. These fair value measurements

10

LIBERTY OILFIELD SERVICES INC.
Notes to Condensed Consolidated and Combined Financial Statements
(Unaudited)

maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company’s own judgments about the assumptions that market participants would use in pricing the asset or liability. The Company discloses the fair values of its assets and liabilities according to the quality of valuation inputs under the following hierarchy:
•
Level 1 Inputs: Quoted prices (unadjusted) in an active market for identical assets or liabilities.
•
Level 2 Inputs: Inputs other than quoted prices that are directly or indirectly observable.
•
Level 3 Inputs: Unobservable inputs that are significant to the fair value of assets or liabilities.
The classification of an asset or liability is based on the lowest level of input significant to its fair value. Those that are initially classified as Level 3 are subsequently reported as Level 2 when the fair value derived from unobservable inputs is inconsequential to the overall fair value, or if corroborating market data becomes available. Assets and liabilities that are initially reported as Level 2 are subsequently reported as Level 3 if corroborating market data is no longer available. Transfers occur at the end of the reporting period. There were no transfers into or out of Levels 1, 2 and 3 during the six months ended June 30, 2018 and 2017 .
The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, long-term debt, and capital lease obligations. These financial instruments do not require disclosure by level. The carrying values of all the Company’s financial instruments included in the accompanying balance sheets approximated or equaled their fair values at June 30, 2018 and December 31, 2017 .
•
The carrying values of cash and cash equivalents, accounts receivable and accounts payable (including accrued liabilities) approximated fair value at June 30, 2018 and December 31, 2017 , due to their short-term nature.
•
The carrying value of amounts outstanding under long-term debt agreements with variable rates approximated fair value at June 30, 2018 and December 31, 2017 , as the effective interest rates approximated market rates.
Nonfinancial assets
The Company estimates fair value to perform impairment tests as required on long-lived assets. The inputs used to determine such fair value are primarily based upon internally developed cash flow models and would generally be classified within Level 3 in the event that such assets were required to be measured and recorded at fair value within the combined financial statements. There were no such measurements required as of June 30, 2018 and December 31, 2017 .
Credit Risk
The Company’s financial instruments exposed to concentrations of credit risk consist primarily of cash and cash equivalents, and trade receivables.
The Company’s cash balances on deposit with financial institutions total $83.3 million and $16.3 million as of June 30, 2018 and December 31, 2017 , respectively, which exceeded FDIC insured limits. The Company regularly monitors these institutions’ financial condition.
The majority of the Company’s customers have stated payment terms of 45 days or less. As of June 30, 2018 and December 31, 2017 , one customer accounted for 16% and 22% of total accounts receivable and unbilled revenue, respectively. The Company mitigates the associated credit risk by performing credit evaluations and monitoring the payment patterns of its customers. During the three months ended June 30, 2018 and 2017 , one customer accounted for 15% and 28% of total revenue, respectively. During the six months ended June 30, 2018 and 2017 , one customer accounted for 16% and 30% of total revenue, respectively.
As of June 30, 2018 and December 31, 2017 , the Company had no provision for doubtful accounts.

Note 8—Equity
Preferred Stock
As of June 30, 2018 the Company had 10,000 shares of preferred stock authorized, par value $0.01 , with none issued and outstanding. If issued, each class or series of preferred stock will cover the number of shares and will have the powers, preferences, rights, qualifications, limitations and restrictions determined by the board of directors, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights, preemptive rights and redemption rights. Except as provided by law or in a preferred stock designation, the holders of preferred stock will not be entitled to vote at or receive notice of any meeting of shareholders.
Class A Common Stock
The Company had a total of 69,958,113 shares of Class A Common Stock outstanding as of June 30, 2018 , which includes 937,716 shares of restricted stock. Holders of Class A Common Stock are entitled to one vote per share on all matters to be voted upon by the stockholders and are entitled to ratably receive dividends when and if declared by the Company’s board of directors.
Class B Common Stock
The Company had a total 48,207,372 shares of Class B Common Stock outstanding as of June 30, 2018 . Holders of the Class B Common Stock are entitled to one vote per share on all matters to be voted upon by stockholders. Holders of Class A Common Stock and Class B Common Stock vote together as a single class on all matters presented to the Company’s stockholders for their vote or approval, except with respect to amendment of certain provisions of the Company’s certificate of incorporation that would alter or change the powers, preferences or special rights of the Class B Common Stock so as to affect them adversely, which amendments must be by a majority of the votes entitled to be cast by the holders of the shares affected by the amendment, voting as a separate class, or as otherwise required by applicable law.
Holders of Class B Common Stock do not have any right to receive dividends, unless the dividend consists of Class B Common Stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B Common Stock paid proportionally with respect to each outstanding share of Class B Common Stock and a dividend consisting of shares of Class A Common Stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A Common Stock on the same terms is simultaneously paid to the holders of Class A Common Stock. Holders of Class B Common Stock do not have any right to receive a distribution upon liquidation or winding up of the Company.
The Liberty LLC Unit holders generally have the right (the “Redemption Right”) to cause Liberty LLC to acquire all or a portion of their Liberty LLC Units (and a corresponding number of shares of Class B Common Stock), for, at Liberty LLC’s election, (i) shares of Class A Common Stock, at a redemption ratio of one share of Class A Common Stock for each Liberty LLC Unit (and corresponding share of Class B Common Stock) redeemed, (subject to conversion rate adjustments for stock splits, stock dividends, and reclassifications and other similar transactions) or (ii) an equivalent amount of cash. Alternatively, upon the exercise of the Redemption Right, the Company (instead of Liberty LLC) will have the right (the “Call Right”) to, for administrative convenience, acquire each tendered Liberty LLC Unit directly from the redeeming Liberty Unit holder for, at its election, (x) one share of Class A Common Stock or (y) an equivalent amount of cash. In addition, upon a change of control of the Company, the Company has the right to require each holder of Liberty LLC Units (other than the Company) to exercise its Redemption Right with respect to some or all of such unitholder’s Liberty LLC Units. In connection with any redemption of Liberty LLC Units pursuant to the Redemption Right or the Call Right, the corresponding number of shares of Class B Common Stock will be canceled.
Net Income per Share
Basic net income per share measures the performance of an entity over the reporting period. Diluted net income per share measures the performance of an entity over the reporting period while giving effect to all potentially dilutive common shares that were outstanding during the period. The Company uses the “if-converted” method to determine the potential dilutive effect of its Class B Common Stock and the treasury stock method to determine the potential dilutive effect of outstanding restricted stock and restricted stock units.

LLC Interest Issuance
Prior to the IPO and Corporate Reorganization, as described in Note 1, Liberty Holdings issued membership interests to investors in exchange for cash consideration. Total member contributions as of December 31, 2017 were $275.7 million , net of commitment and issuance fees. On January 17, 2018, in connection with the Corporate Reorganization, these membership interests were exchanged for Liberty LLC Units. See Note 1 for additional information regarding the Corporate Reorganization.
Unit-Based Compensation
Prior to the IPO and Corporate Reorganization, Liberty Holdings issued Class B units of Liberty Holdings (“Legacy Units”) to certain eligible employees of the Company. The Legacy Units were non-voting, except with respect to such matters that units are entitled to vote as a matter of law. In such cases, each Legacy Unit entitled the holder to 1/1000th of one vote. Certain Legacy Units granted to eligible participants had an assigned benchmark value and were subject to vesting in accordance with the terms of each award letter. Upon termination of the holder’s employment for any reason, Liberty Holdings had the right, but not the obligation, to repurchase from the recipient those vested Legacy Units at fair value.
The Company recognizes compensation expense for equity-based Legacy Units issued to employees based on the grant-date fair value of the awards and each award’s requisite service period. With the assistance from a third-party valuation expert, the Predecessor determined that the Legacy Units issued to employees were deemed to have a de minimis grant-date fair value based on their assigned benchmark values. In connection with the Corporate Reorganization, the unvested Legacy Units were exchanged for 1,258,514 shares of restricted stock with the same terms and requisite vesting conditions as the Legacy Units.

LIBERTY OILFIELD SERVICES INC.

There was no change in the classification of the awards, and the fair value of the awards was the same immediately before and after the exchange. As such, in accordance with ASU 2017-07, modification accounting was not applicable, and the restricted stock awards continue to be recognized at the grant date fair value of the Legacy Units.
Restricted Stock Awards
Restricted stock awards are awards of Class A Common Stock that are subject to restrictions on transfer and to a risk of forfeitures if the award recipient is no longer an employee or director of the Company for any reason prior to the lapse of the restrictions.

Long Term Incentive Plan
On January 11, 2018, the Company adopted the Long Term Incentive Plan (“LTIP”) to incentivize employees, officers, directors and other service providers of the Company and its affiliates. The LTIP provides for the grant, from time to time, at the discretion of the Board or a committee thereof, of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards, substitute awards and performance awards. Subject to adjustment in the event of certain transaction or changes of capitalization in accordance with the LTIP, 12,908,734 shares of Class A Common Stock have been reserved for issuance pursuant to awards under the LTIP. Class A Common stock subject to an award that expires or is canceled, forfeited, exchanged, settled in cash or otherwise terminated without delivery of shares and shares withheld to pay the exercise price of, or to satisfy the withholding obligations with respect to, an award will again be available for delivery pursuant to other awards under the LTIP.
Restricted Stock Units
Restricted stock units (RSUs) granted pursuant to the LTIP, if they vest, will be settled in shares of the Company’s Class A Common Stock. RSUs were granted with vesting terms up to five years. Changes in non-vested RSUs outstanding under the LTIP during the six months ended June 30, 2018 were as follows:

Note 9—Income Taxes
The Company is a corporation and is subject to U.S. federal, state and local income tax on its share of Liberty LLC’s taxable income. As a result of the IPO and Corporate Reorganization, the Company recorded deferred tax assets and liabilities for the difference between the book value of assets and liabilities for financial reporting purposes and those amounts applicable for income tax purposes. Deferred tax assets have been recorded for tax attributes contributed to the Company as part of the Corporate Reorganization. Deferred tax liabilities of $28.6 million have been recorded in connection with the Liberty LLC Units acquired through reorganization. The initial deferred tax liability is recorded as a long term liability and additional paid in capital on the condensed consolidated balance sheet as of June 30, 2018 .
The effective combined U.S. federal and state income tax rate applicable to the Company for the period commencing on January 17, 2018, the date of the Corporate Reorganization, through June 30, 2018 was 13.9% . The Company’s effective tax rate is significantly less than the statutory tax rate of 21.0% primarily due to the shortened taxable period, as the Company was a pass-through entity prior to the IPO, and because no taxes are payable by the Company for the noncontrolling interest’s share of Liberty LLC’s pass through results for federal, state and local income tax reporting. The Company recognized income tax expense of $24.0 million for the period commencing on January 17, 2018, the date of the Corporate Reorganization, through June 30, 2018 , and $15.9 million during the three months ended June 30, 2018 .
Tax Receivable Agreements
In connection with the IPO, on January 17, 2018, the Company entered into two Tax Receivable Agreements (the “TRAs”) with the R/C Energy IV Direct Partnership, L.P. and the Legacy Owners that continued to own Liberty LLC Units (each such person and any permitted transferee, a “TRA Holder” and together, the “TRA Holders”). The TRAs generally provide for the payment by the Company of 85% of the net cash savings, if any, in U.S. federal, state, and local income tax and franchise tax (computed using simplifying assumptions to address the impact of state and local taxes) that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the IPO as a result, as applicable to each TRA Holder, of (i) certain increases in tax basis that occur as a result of the Company’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of such TRA Holder’s Liberty LLC Units in connection with the IPO or pursuant to the exercise of the Redemption Right or the Company’s Call Right, (ii) any net operating losses available to the Company as a result of the Corporate Reorganization, and (iii) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, any payments the Company makes under the TRAs.
The term of each TRA commenced on January 17, 2018, and will continue until all such tax benefits that are subject to such TRA have been utilized or expired, unless the Company experiences a change of control (as defined in the TRAs, which includes certain mergers, asset sales and other forms of business combinations) or the TRAs are terminated early (at the Company’s election or as a result of its breach), and the Company makes the termination payments specified in such TRA.
The amounts payable, as well as the timing of any payments, under the TRAs are dependent upon significant future events and assumptions, including the timing of the redemptions of Liberty LLC Units, the price of our Class A Common Stock at the time of each redemption, the extent to which such redemptions are taxable transactions, the amount of the redeeming unit holder’s tax basis in its Liberty LLC Units at the time of the relevant redemption, the depreciation and amortization periods that apply to the increase in tax basis, the amount of net operating losses available to the Company as a result of the Corporate Reorganization, the amount and timing of taxable income the Company generates in the future, the U.S. federal income tax rate then applicable, and the portion of the Company’s payments under the TRAs that constitute imputed interest or give rise to depreciable or amortizable tax basis. As of June 30, 2018 , there have been no payments associated with the TRA.
Prior to the Corporate Reorganization, one of the Legacy Owners contributed a portion of its member interest in Liberty Holdings to R/C IV Non-U.S. LOS Corp (“R/C IV”). Subsequently, in conjunction with the Corporate Reorganization, R/C IV was contributed to Liberty LLC. R/C IV had net operating loss carryforwards totaling $11.1 million for federal income tax purposes and $7.8 million for certain state income tax purposes. As a result of the Company being in a net income position and the expected utilization of deferred tax assets, the tax attributes contributed to the Company included a deferred tax asset of $2.6 million . As of June 30, 2018 , the Company recognized a $2.3 million payable pursuant to the TRAs, or 85% of the deferred tax asset that is expected to be realized.
Note 10—Defined Contribution Plan
The Company sponsors a 401(k) defined contribution retirement plan covering eligible employees. The Company makes matching contributions, which were temporarily suspended in May 2015, but were resumed in April 2017 at a rate of $1.00 for each $1.00 of employee contribution, subject to a cap of 3% of the employee’s salary. In October 2017, the cap on these contributions was increased to 6% of the employee’s base salary. Contributions made by the Company were $6.7 million and

Litigation
From time to time, the Company is subject to legal and administrative proceedings, settlements, investigations, claims and actions. The Company’s assessment of the likely outcome of litigation matters is based on its judgment of a number of factors including experience with similar matters, past history, precedents, relevant financial and other evidence and facts specific to the matter.

Item 2. Management ’ s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the accompanying financial statements and related notes. The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of a variety of risks and uncertainties, including those described in “Cautionary Note Regarding Forward-Looking Statements” and our Annual Report under the heading “Item 1A. Risk Factors.” We assume no obligation to update any of these forward-looking statements.
Unless the context otherwise requires, references to the terms “Company,” “we,” “us” and “our” refer to the Predecessor for periods prior to the IPO, and Liberty Oilfield Services Inc. and its consolidated subsidiaries for periods following the IPO.
Overview
We are a growing independent provider of hydraulic fracturing services to onshore oil and natural gas exploration and production (“E&P”) companies in North America. We have grown from one active hydraulic fracturing fleet in December 2011 to 22 active fleets in August 2018. The demand for our hydraulic fracturing services exceeds our current capacity, and we expect, based on discussions with customers, to deploy one additional fleet, as well as add additional horsepower to existing fleets, during the fourth quarter of 2018, and add one additional fleet during the first quarter of 2019, for a total of 24 active fleets, representing approximately 1,170,000 hydraulic horsepower, including additional supporting horsepower. We added three fleets during the six months ended June 30, 2018 to bring our total active fleets to 22 as of June 30, 2018. Average active fleets during the six months ended June 30, 2018 and 2017 was 20.4 and 13.1 , respectively, and 21.3 and 14.5 during the three months ended June 30, 2018 and 2017 , respectively. Average active fleets is calculated as our daily average of active fleets for the relevant period. Our additional fleets are currently being built to our specifications. We provide our services primarily in the Permian Basin, the Eagle Ford Shale, the DJ Basin, the Williston Basin and the Powder River Basin.
We believe the following characteristics both distinguish us from our competitors and are the foundations of our business: forming ongoing partnerships of trust and innovation with our customers; developing and utilizing technology to maximize well performance; and promoting a people-centered culture focused on our employees, customers and suppliers. We have developed strong relationships with our customers by investing significant time in fracture design collaboration, which substantially enhances their production economics. Our technological innovations have become even more critical as E&P companies have increased the completion complexity and fracture intensity of horizontal wells. We are proactive in developing innovative solutions to industry challenges, including developing: (i) our proprietary databases of U.S. unconventional wells to which we apply our proprietary multi-variable statistical analysis technologies to provide differential insight into fracture design optimization; (ii) our Liberty Quiet Fleet ™ design which significantly reduces noise levels compared to conventional hydraulic fracturing fleets; and (iii) our hydraulic fracturing fluid system tailored to the reservoir properties in the DJ Basin which materially reduces completion costs without compromising production. We foster a people-centered culture built around honoring our commitments to customers, partnering with our suppliers and hiring, training and retaining people that we believe to be the best talent in our field, enabling us to be one of the safest and most efficient hydraulic fracturing companies in the United States.
Recent Trends and Outlook
Demand for our hydraulic fracturing services is predominantly influenced by the level of drilling and completion by E&P companies, which, in turn, depends largely on the current and anticipated profitability of developing oil and natural gas reserves. More specifically, demand for our hydraulic fracturing services is driven by the completion of hydraulic fracturing stages in unconventional wells, which, in turn, is driven by several factors including rig count, well count, service intensity and the timing and style of well completions.
Macro Conditions
In the second quarter of 2018, the price of West Texas Intermediate crude oil averaged $68.02 compared with an average of $62.91 for the first quarter of 2018 and an average of $48.14 for the second quarter of 2017. This has led to an increase in our customer activity levels, which is commonly measured by the active rig count. In the second quarter of 2018, the horizontal rig count in North America averaged 911 compared to 831 in the first quarter of 2018 and 747 for the second quarter of 2017, according to a report by Baker Hughes, a GE company.
Although there is uncertainty in the market about the potential effect of Permian Basin takeaway constraints, Liberty's operations in Permian continue to grow and thrive. The developing imbalance for frac services in the Permian has not yet impacted Liberty fleets. Markets outside the Permian remain constructive. Based on these market conditions, the diversity of

19


Liberty's operating footprint, conversations with our customers and other factors, we expect demand for frac services to remain strong during 2018, especially for our high-efficiency frac fleets.
How We Evaluate Our Operations
We use a variety of qualitative, operational and financial metrics to assess our performance. First and foremost of these is a qualitative assessment of customer satisfaction because ensuring we are a valuable partner to our customers is the key to achieving our quantitative business metrics. Among other measures, management considers each of the following:
Revenue;
Operating Income (Loss);
Net Income;
Net Income per Share;
EBITDA;
Adjusted EBITDA; and
Annualized Adjusted EBITDA per Average Active Fleet.
Revenue
We analyze our revenue by comparing actual monthly revenue to our internal projections for a given period and to prior periods to assess our performance. We also assess our revenue in relation to the number of fleets we have deployed (revenue per average active fleet) from period to period.
Operating Income (Loss)
We analyze our operating income (loss), which we define as revenues less direct operating expenses, depreciation and amortization and general and administrative expenses, to measure our financial performance. We believe operating income is a meaningful metric because it provides insight on profitability and true operating performance based on the historical cost basis of our assets. We also compare operating income to our internal projections for a given period and to prior periods.
EBITDA, Adjusted EBITDA and Annualized Adjusted EBITDA per Average Active Fleet
We view EBITDA, Adjusted EBITDA and Annualized Adjusted EBITDA per Average Active Fleet as important indicators of performance. We define EBITDA as net income (loss) before interest, income taxes, depreciation and amortization. We define Adjusted EBITDA as EBITDA adjusted to eliminate the effects of items such as new fleet or new basin start-up costs, costs of asset acquisition, gain or loss on the disposal of assets, asset impairment charges, bad debt reserves, and non-recurring expenses that management does not consider in assessing ongoing operating performance. Average Active Fleets is calculated as the daily average of the number of active fleets for the period presented. Annualized Adjusted EBITDA per Average Active Fleet is calculated as Adjusted EBITDA annualized, divided by the Average Active Fleets for the same period. See “—Comparison of Non-GAAP Financial Measures” for more information and a reconciliation of EBITDA and Adjusted EBITDA to net income (loss), the most directly comparable financial measure calculated and presented in accordance with GAAP.

Revenue
Our revenue increased $281.4 million , or 81.1% , to $628.1 million for the three months ended June 30, 2018 compared to $346.7 million for three months ended June 30, 2017 . The increase was due to the combined effect of a 46.9% increase in average active fleets deployed and a 23.3% increase in revenue per average active fleet. Our revenue per average active fleet increased to approximately $29.5 million for the three months ended June 30, 2018 as compared to approximately $23.9 million for the three months ended June 30, 2017 , based on 21.3 and 14.5 average active fleets deployed during those respective periods. The increase in revenue per active fleet was due to improved pricing and throughput in conjunction with increased demand for our services.
Cost of Services
Cost of services (excluding depreciation and amortization) increased $187.8 million , or 70.2% , to $455.5 million for the three months ended June 30, 2018 compared to $267.6 million for the three months ended June 30, 2017 . The higher expense is due to an increase in services provided and reflects a $129.0 million increase attributable to materials, which was driven by a 56.6% increase in material volumes in the three months ended June 30, 2018 compared to the same period in 2017 . Personnel costs increased by $26.2 million, or 53.2%, to support the increased activity, including a 46.9% increase in average active fleets deployed. Additionally, the cost of components used in our repairs and maintenance operations increased by $22.7 million for the three months ended June 30, 2018 as compared to the three months ended June 30, 2017 .
General and Administrative Expenses
General and administrative expenses increased by $7.3 million , or 36.4% , to $27.3 million for the three months ended June 30, 2018 compared to $20.0 million for the three months ended June 30, 2017 . Payroll and benefits and related office expenses increased approximately $2.5 million and $1.7 million, respectively, in connection with the increase in head count to support our expanded scope of operations and the six fleets deployed during the twelve months ended June 30, 2018 . In addition, non-cash stock based compensation expense of $1.1 million was recognized during the three months ended June 30, 2018 compared to $0 during the same period in the prior year.
Depreciation and Amortization
Depreciation and amortization expense increased $13.1 million , or 74.7% , to $30.6 million for the three months ended June 30, 2018 compared to $17.5 million for the three months ended June 30, 2017 , due to six additional hydraulic fracturing fleets deployed during the twelve months ended June 30, 2018 .

21


Operating Income
We realized operating income of $114.2 million for the three months ended June 30, 2018 compared to $41.5 million for the three months ended June 30, 2017 , primarily due to the increased number of hydraulic fracturing fleets deployed and the higher revenue per average active fleet in response to increased demand for our services described above. Generally, our financial results have improved significantly due to the increased drilling and completion activity by E&P companies during the recovery of the oil and gas industry beginning in the third quarter of 2016.
Interest Expense
The increase in interest expense of $1.0 million , or 41.0% , during the three months ended June 30, 2018 compared to the three months ended June 30, 2017 was primarily due to $1.7 million of deferred financing costs written off in connection with the pay down of 35% of the term loan and $0.9 million prepayment penalty assessed in connection with the pay down offset by a $0.8 million decrease in related party interest expense and a $0.8 million decrease in interest expense due to the lower average borrowings outstanding during the three months ended June 30, 2018 compared to the same period in 2017 .
Net Income before Tax Expense
We realized net income before tax expense of $110.7 million for the three months ended June 30, 2018 compared to $39.0 million for the three months ended June 30, 2017 . The increase in net income is primarily attributable to our expanded scope of operations following the deployment of six additional hydraulic fracturing fleets during the twelve months ended June 30, 2018 .
Income Tax Expense
Our operations are taxed at a combined U.S. federal and state effective tax rate of 13.9%. As a pass-through entity prior to the IPO, our Predecessor was subject only to the Texas margin tax at a statutory rate of 1.0% and was not subject to U.S. federal income tax. We recognized $15.9 million of expense for the three months ended June 30, 2018 compared to $0 recognized during the three months ended June 30, 2017 . This increase was attributable to our status as a corporation subject to U.S. federal income tax as well as a net increase in operating income, the components of which are discussed above.

The increase was due to the combined effect of a 55.7% increase in average active fleets deployed and a 20.4% increase in revenue per average active fleet. Our revenue per average active fleet increased to approximately $55.1 million for the six months ended June 30, 2018 as compared to approximately $45.7 million for the six

22


months ended June 30, 2017 , based on 20.4 and 13.1 average active fleets deployed during those respective periods. The increase in revenue per active fleet was due to improved pricing and throughput in conjunction with increased demand for our services.
Cost of Services
Cost of services (excluding depreciation and amortization) increased $353.0 million , or 73.7% , to $832.3 million for the six months ended June 30, 2018 compared to $479.3 million for the six months ended June 30, 2017 . The higher expense is due to an increase in services provided and reflects a $237.8 million increase attributable to materials, which was driven by a 59.1% increase in material volumes in the six months ended June 30, 2018 compared to the same period in 2017 . Personnel costs increased by $59.7 million, or 70.0%, to support the increased activity, including a 55.7% increase in average active fleets deployed. Additionally, the cost of components used in our repairs and maintenance operations increased by $36.2 million for the six months ended June 30, 2018 as compared to the six months ended June 30, 2017 .
General and Administrative Expenses
General and administrative expenses increased by $11.9 million , or 32.0% , to $49.0 million for the six months ended June 30, 2018 compared to $37.1 million for the six months ended June 30, 2017 . Payroll and benefits and related office expenses increased approximately $4.5 million and $3.2 million, respectively, in connection with the increase in head count to support our expanded scope of operations and the six fleets deployed during the twelve months ended June 30, 2018 . In addition, non-cash stock based compensation expense of $1.1 million was recognized during the six months ended June 30, 2018 compared to $0 during the same period in the prior year.
Depreciation and Amortization
Depreciation and amortization expense increased $27.0 million , or 85.1% , to $58.6 million for the six months ended June 30, 2018 compared to $31.7 million for the six months ended June 30, 2017 , due to six additional hydraulic fracturing fleets deployed during the twelve months ended June 30, 2018 .
Operating Income
We realized operating income of $182.8 million for the six months ended June 30, 2018 compared to $51.1 million for the six months ended June 30, 2017 , primarily due to the increased number of hydraulic fracturing fleets deployed and the higher revenue per average active fleet in response to increased demand for our services described above. Generally, our financial results have improved significantly due to the increased drilling and completion activity by E&P companies during the recovery of the oil and gas industry beginning in the third quarter of 2016.
Interest Expense
The increase in interest expense of $6.1 million , or 153.2% , during the six months ended June 30, 2018 compared to the six months ended June 30, 2017 was primarily due to $1.7 million of deferred financing costs written off in connection with the pay down of 35% of the term loan and $0.9 million prepayment penalty assessed in connection with the pay down and a $3.5 million increase in interest expense due to higher weighted average interest rate on borrowings outstanding during the six months ended June 30, 2018 compared to the same period in 2017 .
Net Income before Tax Expense
We realized net income before tax expense of $172.7 million for the six months ended June 30, 2018 compared to $47.2 million for the six months ended June 30, 2017 . The increase in net income is primarily attributable to our expanded scope of operations following the deployment of six additional hydraulic fracturing fleets during the twelve months ended June 30, 2018 .
Income Tax Expense
Our operations are taxed at a combined U.S. federal and state effective tax rate of 13.9%. As a pass-through entity prior to the IPO, our Predecessor was subject only to the Texas margin tax at a statutory rate of 1.0% and was not subject to U.S. federal income tax. Subsequent to the IPO, we recognized $24.0 million of expense for the period commencing on January 17, 2018 through June 30, 2018 compared to none recognized during the six months ended June 30, 2017 . This increase was attributable to our status as a corporation subject to U.S. federal income tax as well as a net increase in operating income, the components of which are discussed above.

Comparison of Non-GAAP Financial Measures
We view EBITDA and Adjusted EBITDA as important indicators of performance. We define EBITDA as net income before interest, income taxes, depreciation and amortization. We define Adjusted EBITDA as EBITDA adjusted to eliminate the effects of items such as new fleet or new basin start-up costs, costs of asset acquisition, gain or loss on the disposal of assets, asset impairment charges, bad debt reserves, and non-recurring expenses that management does not consider in assessing ongoing operating performance.
Our board of directors, management, investors and lenders use EBITDA and Adjusted EBITDA to assess our financial performance because it allows them 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) and other items that impact the comparability of financial results from period to period. We present EBITDA and Adjusted EBITDA because we believe they provide useful information regarding the factors and trends affecting our business in addition to measures calculated under GAAP. Additionally, the calculation of Adjusted EBITDA complies with the definition of Consolidated EBITDA and other provisions of our Credit Facilities. See “—Debt Agreements.”
Note Regarding Non-GAAP Financial Measures
EBITDA and Adjusted EBITDA are not financial measures presented in accordance with GAAP. We believe that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing our financial performance and results of operations. Net income (loss) is the GAAP measure most directly comparable to EBITDA and 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 an analytical tool due to exclusion of some but not all items that affect the most directly comparable GAAP financial measures. You should not consider EBITDA or Adjusted EBITDA in isolation or as substitutes for an analysis of our results as reported under GAAP. Because EBITDA and Adjusted EBITDA 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.
The following tables present a reconciliation of EBITDA and Adjusted EBITDA to our net income, which is the most directly comparable GAAP measure for the periods presented:

Liquidity and Capital Resources
Overview
Our primary sources of liquidity prior to the IPO were cash flows from operations, capital contributions from our owners and borrowings under our Credit Facilities. Our primary uses of capital have been capital expenditures to support organic growth and funding ongoing operations, including maintenance and fleet upgrades.
Cash and cash equivalents increased by $67.0 million to $83.3 million as of June 30, 2018 compared to $16.3 million as of December 31, 2017 , primarily attributable to net proceeds from the IPO. Going forward, we intend to finance the majority of our capital expenditures, contractual obligations and working capital needs with proceeds from the IPO and operating cash flows. We believe that our operating cash flow and available borrowings under our Credit Facilities will be sufficient to fund our operations for at least the next twelve months.

Analysis of Cash Flow Changes Between the Six Months Ended June 30, 2018 and 2017
Operating Activities . Net cash provided by operating activities was $109.2 million for the six months ended June 30, 2018 , compared to $45.6 million for the six months ended June 30, 2017 . The $63.6 million increase in cash from operating activities was attributable to a $524.1 million increase in revenues, offset by a $364.9 million increase in cash based operating expenses as well as an increase in funds used to satisfy working capital obligations.
Investing Activities . Net cash used in investing activities was $137.8 million for the six months ended June 30, 2018 , compared to $204.9 million for the six months ended June 30, 2017 . Capital expenditures, including amounts in Accounts Payable and Accrued Liabilities, were $128.4 million for the six months ended June 30, 2018 compared to $198.7 million for the six months end June 30, 2017 . The $67.0 million decrease in net cash used in investing activities was primarily due to the acquisition of Titan Frac Services LLC and other Texas real estate properties during the six months ended June 30, 2017 .
Financing Activities . Net cash provided by financing activities was $95.7 million for the six months ended June 30, 2018 , compared to $148.5 million for the six months ended June 30, 2017 . The $52.8 million decrease in cash provided by financing activities was primarily due to net repayment on debt of $91.5 million and distributions to noncontrolling interest holders of $13.0 million during the six months ended June 30, 2018 compared to net borrowings of $110.0 million and $39.8 million in proceeds from issuance of redeemable common units received during the six months ended June 30, 2017, offset by $198.4 million in net proceeds from the IPO.
ABL Facility
The Company’s ABL Facility provides for a line of credit up to $250.0 million, subject to certain borrowing base limitations based on a percentage of eligible accounts receivable and inventory. As of June 30, 2018 , the borrowing base was calculated to be $235.4 million with no amounts drawn and an outstanding letter of credit for $0.3 million , leaving $235.1 million of availability. Borrowings under the ABL Facility bear interest at LIBOR or a base rate, plus an applicable LIBOR

25


margin of 1.5% to 2.0% or base rate margin of 0.5% to 1.0%, as defined in the ABL Facility credit agreement. The ABL Facility is not subject to financial covenants unless liquidity, as defined in the ABL Facility credit agreement, drops below a specified level. Under the ABL Facility, the Company is required to maintain a minimum fixed charge coverage ratio, as defined in the ABL Facility credit agreement, of 1.0 to 1.0 for each period if excess availability is less than 10% of the borrowing base or $12.5 million, whichever is greater. The Company was in compliance with these covenants as of June 30, 2018 .
Income Taxes
The Company is a corporation and is subject to U.S. federal, state and local income tax on its share of Liberty LLC’s taxable income. As a result of the IPO and Corporate Reorganization, the Company recorded deferred tax assets and liabilities for the difference between the book value of assets and liabilities for financial reporting purposes and those amounts applicable for income tax purposes. Deferred tax assets have been recorded for tax attributes contributed to the Company as part of the reorganization. Deferred tax liabilities of $28.6 million have been recorded in connection with the Liberty LLC Units acquired through the Corporate Reorganization.
The effective combined U.S. federal and state income tax rate applicable to the Company for the six months ended June 30, 2018 was 13.9% . The Company’s effective tax rate is significantly less than the statutory tax rate of 21.0% primarily because no taxes are payable by the Company for the noncontrolling interest’s share of Liberty LLC’s pass through results for federal, state and local income tax reporting. The Company recognized income tax expense of $24.0 million for the six months ended June 30, 2018 .
Tax Receivable Agreements
In connection with the IPO, on January 17, 2018, the Company entered into the TRAs with the TRA Holders. The TRAs generally provide for the payment by the Company of 85% of the net cash savings, if any, in U.S. federal, state, and local income tax and franchise tax (computed using simplifying assumptions to address the impact of state and local taxes) that the Company actually realizes (or is deemed to realize in certain circumstances) in periods after the IPO as a result, as applicable to each TRA Holder, of (i) certain increases in tax basis that occur as a result of the Company’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of such TRA Holder’s Liberty LLC Units in connection with the IPO or pursuant to the exercise of the Redemption Right or the Company’s Call Right, (ii) any net operating losses available to the Company as a result of the Corporate Reorganization, and (iii) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, any payments the Company makes under the TRAs.
With respect to obligations the Company expects to incur under the TRAs (except in cases where the Company elects to terminate the TRAs early, the TRAs are terminated early due to certain mergers, asset sales, or other changes of control or the Company has available cash but fails to make payments when due), generally the Company may elect to defer payments due under the TRAs if the Company does not have available cash to satisfy its payment obligations under the TRAs or if its contractual obligations limit its ability to make such payments. Any such deferred payments under the TRAs generally will accrue interest. In certain cases, payments under the TRAs may be accelerated and/or significantly exceed the actual benefits, if any, the Company realizes in respect of the tax attributes subject to the TRAs. The Company accounts for amounts payable under the TRAs in accordance with ASC Topic 450, Contingent Consideration.
If the Company experiences a change of control (as defined under the TRAs) or the TRAs otherwise terminate early, the Company’s obligations under the TRAs could have a substantial negative impact on its liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, or other forms of business combinations or changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreements.
Critical Accounting Policies and Estimates
The consolidated financial statements are prepared in accordance with U.S. GAAP, which require us to make estimates and assumptions (see Note 1 to the combined financial statements included in the Annual Report).  We believe that some of our accounting policies involve a higher degree of judgment and complexity than others.  As of December 31, 2017, our critical accounting policies included revenue recognition, estimating the recoverability of accounts receivable, inventory valuation, accounting for income taxes, accounting for long-lived assets, accounting for derivative instruments, and accounting for abnormally low production levels.  These critical accounting policies are discussed more fully in the Annual Report.
Effective January 1, 2018, the Company adopted Accounting Standard Codification Topic 606- Revenue from Contracts with Customers (see Note 1 to the condensed consolidated and combined financial statements included in this Form 10-Q). There have been no other changes in our evaluation of our critical accounting policies since December 31, 2017.

26


Off Balance Sheet Arrangements
We have no material off balance sheet arrangements as of June 30, 2018 , except for the operating leases and purchase commitments under supply agreements as disclosed above under “Item 1. Financial Statements—Note 12—Commitments & Contingencies.” As such, we are not materially exposed to any other financing, liquidity, market or credit risk that could arise if we had engaged in such financing arrangements.

27


Item 3. Quantitative and Qualitative Disclosure about Market Risk
Interest Rate Risk
At June 30, 2018 , we had $113.0 million of debt outstanding, with a weighted average interest rate of 9.7% . Interest is calculated under the terms of our Credit Facilities based on our selection, from time to time, of one of the index rates available to us plus an applicable margin that varies based on certain factors. Assuming no change in the amount outstanding, the impact on interest expense of a 1% increase or decrease in the weighted average interest rate would be approximately $1.1 million per year. We do not currently have or intend to enter into any derivative arrangements to protect against fluctuations in interest rates applicable to our outstanding indebtedness.
Item 4. Controls and Procedures
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2018 . The evaluation included certain internal control areas in which we have made and are continuing to make changes to improve and enhance controls. Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s (the “SEC”) rules and forms and that such information is accumulated and communicated to management, including the principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive officer and principal financial officer concluded that, as of June 30, 2018 , our disclosure controls and procedures were effective, at the reasonable assurance level. Any controls and procedures, no matter how well designed and operated can only provide reasonable assurance of achieving the desired control objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of all possible controls and procedures.
There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION
Item 1. Legal Proceeding

On February 23, 2017, SandBox filed suit in the Houston Division of the U.S. District Court for the Southern District of Texas against Proppant Express Investments, LLC, PropX, and LOS. LOS is party to a services agreement with PropX. SandBox alleges that LOS willfully infringes multiple U.S. patents and has breached an agreement between SandBox and LOS by “directing, controlling, and funding” IPR requests before the USPTO. In July 2018, SandBox requested permission from the court to allege additional breach of contract claims against LOS, including alleged breaches of a confidentiality agreement and an exclusive purchasing covenant. SandBox seeks both monetary and injunctive relief from the court, as well as attorney’s fees and costs. We intend to vigorously defend ourselves against the claims brought by SandBox.
We are named defendants in certain lawsuits, investigations and claims arising in the ordinary course of conducting our business, including certain environmental claims and employee-related matters, and we expect that we will be named defendants in similar lawsuits, investigations and claims in the future. While the outcome of these lawsuits, investigations and claims cannot be predicted with certainty, we do not expect these matters to have a material adverse impact on our business, results of operations, cash flows or financial condition. We have not assumed any liabilities arising out of these existing lawsuits, investigations and claims.
Item 1A. Risk Factors
In addition to the other information set forth in this Quarterly Report, you should carefully consider the risk factors and other cautionary statements described under the heading “Item 1A. Risk Factors” included in the Annual Report and the risk factors and other cautionary statements contained in our other SEC filings, which could materially affect our businesses, financial condition or future results. There have been no material changes in our risk factors from those described in our Annual Report or our other SEC filings.
