DESCRIPTION OF BUSINESS	FTS INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 1 — DESCRIPTION OF BUSINESS Throughout the notes to these consolidated financial statements, the terms “the Company,” “we,” “us,” “our” or “ours” refer to FTS International, Inc., together with its consolidated subsidiaries. Certain prior year financial statements are not comparable to our current year financial statements due to the adoption of fresh start accounting. References to “Successor” or “Successor Company” relate to the financial position and results of operations of the reorganized Company subsequent to November 19, 2020. References to “Predecessor” or “Predecessor Company” relate to the financial position and results of operations of the Company prior to, and including, November 19, 2020. We are one of the largest providers of hydraulic fracturing services in North America. Our services enhance hydrocarbon flow from oil and natural gas wells drilled by exploration and production (“E&P”), companies in shale and other unconventional resource formations. Our customers include leading E&P companies that specialize in unconventional oil and natural gas resources in North America. We operate in the most active oil and gas basins in the United States. Substantially all of our business activities support our well completion services. We manage our business, allocate resources, and assess our financial performance on a consolidated basis; therefore, we do not have separate operating segments. In 2014, the Predecessor Company entered into a joint venture agreement with the Sinopec Oilfield Service Corporation (“Sinopec”). This joint venture collaboration offered hydraulic stimulation services in China. The joint venture company, SinoFTS Petroleum Services Ltd. (“SinoFTS”), was owned 55% by Sinopec and 45% by the Company. SinoFTS serves both Sinopec and other E&P companies in China. In August 2019, FTSI closed on the sale of its 45% equity ownership interest in SinoFTS, to Sinopec. In exchange, FTSI, through its affiliate FTS International Netherlands B.V., received consideration of $26.9 million for the sale of its equity interest, and through FTS International Services, LLC, received a royalty fee of $5.8 million for a license for its intellectual property use and for future limited support of the joint venture’s operations. After conducting an analysis of the relative fair values of the equity interest and royalty fee, FTSI allocated $30.7 million of the total consideration received to the sale of its equity interest and $2.0 million to the prepaid royalty fee. FTSI recognized a gain of $7.0 million on the sale of its equity interest. The prepaid royalty fee will be recognized over approximately six years. Concentrations of Risk Our business activities are concentrated in the well completion services segment of the oilfield services industry in the United States. The market for these services is cyclical, and we depend on the willingness of our customers to make operating and capital expenditures to explore for, develop, and produce oil and natural gas in the United States. The willingness of our customers to undertake these activities depends largely upon prevailing industry conditions that are predominantly influenced by current and expected prices for oil and natural gas. Historically, a low commodity-price environment has caused our customers to significantly reduce their hydraulic fracturing activities and the prices they are willing to pay for those services. During these periods, these customer actions materially adversely affected our business, financial condition and results of operations. Our customer base has historically been concentrated. Our business, financial condition and results of operations could be materially adversely affected if one or more of our significant customers ceases to engage us for our services on favorable terms, or at all, or fails to pay, or delays in paying, us significant amounts of our outstanding receivables. For the Successor period of November 20, 2020 to December 31, 2020 we had 6 customers make up over 10% of our consolidated revenue. These six customers represented 81% of our consolidated revenue; this level of customer concentration is partially due to the short time period included in the Successor period and may not be representative of customer concentration levels over a longer time period, such as a full fiscal year. For the Predecessor period of January 1, 2020 through November 19, 2020 we had one customer make up over 10% of our consolidated revenue. This customer represented 12% of our consolidated revenue. For the year ended December 31, 2019 we had two customers make up over 10% of our consolidated revenue. These two customers represented 26% of our consolidated revenue. For the year ended December 31, 2018 we had two customers make up over 10% of our consolidated revenue. These two customers represented 24% of our consolidated revenue. The loss of any of our largest existing customers could have a material adverse effect on our results of operations. While we view revenue as an important metric in assessing customer concentration, we also compare and manage our customer portfolio based on the number of fleets we place with each customer. Related Parties We have historically provided services and sold equipment to Chesapeake Energy Corporation and its affiliates (“Chesapeake”), which beneficially owned approximately 20% of the Predecessor’s common stock, and had the right to designate two individuals to serve on our board of directors prior to November 19, 2020. Revenue earned from Chesapeake was $0.7 million, $0.1 million and $92.9 million in Predecessor period of 2020, 2019 and 2018, respectively. At both December 31, 2020 and 2019, we had accounts receivable balances of zero from Chesapeake. We sold equipment to SinoFTS for zero, $0.9 million and $0.3 million in 2020, 2019 and 2018, respectively. All revenue earned from SinoFTS is based on prevailing market prices. At both December 31, 2020 and 2019, we had accounts receivable balances of zero from this related party.

The holders of Notes and holders of the claims under the Term Loan Agreement received their proportionate distribution of approximately 90.1% of our common stock (subject to dilution by the warrants issued pursuant to the Plan and the MIP) plus their pro rata share of $30.7 million cash distribution. The holders of claims in connection with the termination of the supply agreement between the Predecessor and Covia Holding Corporation received, in exchange for their claims, a $12.5 million cash distribution and 0.5% of our common stock (subject to dilution by the warrants issued pursuant to the Plan and the MIP). Shares of Class A common stock were also issued to a holder of certain termination claims under the Plan.

FRESH START ACCOUNTING
FRESH START ACCOUNTING	NOTE 3 — FRESH START ACCOUNTING Fresh Start Accounting Upon emergence from bankruptcy, we met the criteria and were required to adopt fresh start accounting in accordance with ASC Topic 852, Reorganizations, which on the emergence date resulted in a new entity, the Successor, for financial reporting purposes, with no beginning retained earnings or deficit as of the fresh start reporting date. The criteria requiring fresh start accounting are: (i) the holders of then-existing voting shares of the Predecessor received less than 50 percent of the new voting shares of the Successor outstanding upon emergence from bankruptcy, and (ii) the reorganization value of the Company’s assets immediately prior to confirmation of the Plan was less than the total of all post-petition liabilities and allowed claims. The Company applied fresh start accounting effective November 19, 2020, the Effective Date. As such, fresh start accounting is reflected in the accompanying consolidated balance sheet as of December 31, 2020 and related fresh start adjustments are included in the accompanying statement of operations for the period from January 1, 2020 through November 19, 2020. As a result of the application of fresh start accounting and the effects of the implementation of the Plan, the financial statements for the period after November 19, 2020 will not be comparable with the financial statements prior to and including November 19, 2020. Reorganization Value Reorganization value represents the fair value of the Successor’s total assets and is intended to approximate the amount a willing buyer would pay for the assets immediately after restructuring. Under fresh start accounting, the Company allocated the reorganization value to its individual assets based on their estimated fair values. The Company’s reorganization value is derived from an estimate of enterprise value. Enterprise value represents the estimated fair value of an entity’s long-term debt and other interest-bearing liabilities and stockholders’ equity less unrestricted cash and cash equivalents. The Company estimated the enterprise value of the Successor to be $266 million at the Effective Date, which was in the Bankruptcy Court approved range of $190 million and $290 million. The enterprise value was derived from an independent valuation with the assistance of a third-party valuation advisor. Specific valuation approaches and key assumptions used to arrive at the reorganization value, and the value of discrete assets and liabilities resulting from the application of fresh start accounting, are described below in greater detail within the valuation process. Although the Company believes the assumptions and estimates used to develop enterprise value and reorganization value are reasonable and appropriate, different assumptions and estimates could materially impact the analysis and resulting conclusions. The assumptions used in estimating these values are inherently uncertain and require judgment. The following table reconciles the Company’s enterprise value to the fair value of the Successor’s common stock as of the Effective Date. ​ ​ ​ ​ ​ ​ ​ November 19, (In millions) ​ 2020 Enterprise value ​ $ 266.3 Plus: Excess cash (1) ​ ​ 13.3 Fair value of Successor equity ​ $ 279.6 ​ ​ The following table reconciles the Company’s enterprise value to the reorganization value as of the Effective Date: ​ ​ ​ ​ ​ ​ ​ November 19, (In millions) ​ 2020 Enterprise value ​ $ 266.3 Plus: Excess cash (1) ​ ​ 13.3 Plus: Current liabilities ​ ​ 36.4 Plus: Non-interest-bearing non-current liabilities ​ ​ 6.2 Reorganization value of Successor assets ​ $ 322.2 ​ (1) Excess cash of $13.3 million is calculated by taking the Company's Successor cash and cash equivalents balance of $88.3 million less $75.0 million of minimum cash required to operate the business as determined by management. The minimum cash required to operate the business of $75.0 million was also utilized in the estimation of the range of enterprise values included in the Plan and approved by the Bankruptcy Court. Valuation Process The fair values of our principal assets, including inventories, land, buildings, and improvements, service equipment, and intangible assets were estimated with the assistance of third-party valuation advisors as of the Effective Date. In addition, we also estimated the fair value of the Company’s warrants as of the Effective Date. Inventories Inventories include parts, chemicals, and other raw materials. The fair value of the parts inventory was determined using a combination of the cost and income approaches. The cost approach estimates the fair value of an asset based on the cost to reconstruct or replace it with another of similar utility, with adjustments for physical deterioration and identified obsolescence. The income approach was used to quantify the economic support available for the parts inventory based on the enterprise value estimated for the Company. For the chemicals and other materials inventory, the Company determined that the book value as the proxy for fair value. Property, Plant, and Equipment Land, Buildings, and Improvements The fair value of land, buildings, and improvements was determined using a combination of the cost and market approaches. To determine the fair value of buildings and site improvements, the cost and market approaches were used. As part of the valuation process, information was obtained describing physical attributes such as land and building size, construction dates, and general improvement details. In applying the cost approach, the replacement cost was determined based on the current cost to construct improvements with similar utility, using modern materials and current standards, design, and layout. To determine the fair value of land and improvements, the market approach was used based on third party databases identifying listings of recent sales and comparable properties within pertinent market areas. Service Equipment and Other The fair value of the service equipment and other was estimated using a combination of the cost, market, and income approaches. The cost approach was primarily utilized, with the application of the market approach for selected assets based upon the specific characteristics being appraised. The cost approach measures the value of an asset based on the cost to reconstruct or replace it with another of similar utility, with adjustments for physical deterioration and identified obsolescence. The market approach measures the value of an asset through an analysis of recent sales or offerings of comparable assets. The income approach was used to quantify the economic support available for the service equipment and other based on the enterprise value estimated for the Company. Intangible Assets The fair value of intangible assets such as customer relationships, in-house developed software, and tradename was determined using a combination of the cost, market, and income approaches. To determine the fair value of customer relationships, the income approach was used based on the present value of the incremental after-tax cash flows attributable to the existing customer cash flow after deducting the appropriate contributory asset charges. The discount rate utilized to present-value the after-tax cash flows was selected based on consideration of the overall business risks and risks associated with the asset being valued. To determine the fair value of the in-house developed software, the cost replacement method, a form of the cost approach, was used. To determine the fair value of the tradename, the Royalty Savings Method, a variation of the income approach, was used. The estimated royalty rate was determined by observing publicly available royalty rates information for similar companies with similar assets. The forecasted cash flows expected to be generated as a result of the royalty savings were discounted to present value utilizing a discount rate considering overall business risks and risks associated with the asset being valued. Warrants The fair value of the warrants issued upon the Effective Date was estimated using the Black-Scholes-Merton option pricing model. The Black-Scholes-Merton model is an option pricing model used to estimate the fair value of options and warrants based on the following input assumptions: stock price, strike price, term, risk-free rate, volatility, and dividend yield. In using the Black-Scholes-Merton option pricing model to fair value the warrants, the following assumptions were used: market observable stock price on the Effective Date; strike prices of $33.04 and $37.14 for Tranche 1 and Tranche 2 warrants, respectively; expected volatility of 65.0%; risk-free rate of 0.22%; and an expected dividend yield of 0.0%. The expected volatility assumption was estimated using market data related to the Company and certain similar publicly traded entities with considerations for differences in size and leverage of the Company versus the publicly traded entities. The strike prices and term assumptions were based on the contractual term of the warrants. The risk-free rate assumption was based on United States Constant Maturity Treasury rates. ​ Consolidated Balance Sheet The following illustrates the effects on the Company’s consolidated balance sheet due to the reorganization and fresh start accounting adjustments. The explanatory notes following the table below provide further details on the adjustments, including the assumptions and methods used to determine fair value for its assets, liabilities, and warrants. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of November 19, 2020 ​ ​ (in millions) ​ ​ Predecessor ​ Reorganization ​ Fresh Start ​ Successor ​ ​ Company ​ Adjustments ​ Adjustments ​ Company ASSETS ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Current assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 146.7 ​ $ (58.4) (a) $ — ​ $ 88.3 Accounts receivable, net ​ ​ 30.1 ​ ​ — ​ ​ — ​ ​ 30.1 Inventories ​ ​ 33.5 ​ ​ — ​ ​ (2.2) (k) ​ 31.3 Prepaid expenses and other current assets ​ ​ 19.0 ​ ​ 10.1 (b) ​ (5.3) (l) ​ 23.8 Total current assets ​ ​ 229.3 ​ ​ (48.3) ​ ​ (7.5) ​ ​ 173.5 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Property, plant, and equipment, net ​ ​ 177.2 ​ ​ — ​ ​ (42.0) (m) ​ 135.2 Operating lease right-of-use assets ​ ​ 4.7 ​ ​ — ​ ​ — ​ ​ 4.7 Intangible assets, net ​ ​ 29.5 ​ ​ — ​ ​ (22.1) (n) ​ 7.4 Other assets ​ ​ 1.4 ​ ​ 0.2 (c) ​ (0.2) (o) ​ 1.4 Total assets ​ $ 442.1 ​ $ (48.1) ​ $ (71.8) ​ $ 322.2 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ LIABILITIES AND STOCKHOLDERS’ (DEFICIT) EQUITY ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Current liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accounts payable ​ $ 20.3 ​ $ 0.8 (d) $ — ​ $ 21.1 Accrued expenses ​ ​ 11.6 ​ ​ 0.2 (e) ​ — ​ ​ 11.8 Current portion of operating lease liabilities ​ ​ 3.2 ​ ​ — ​ ​ — ​ ​ 3.2 Other current liabilities ​ ​ 12.8 ​ ​ (12.5) (f) ​ — ​ ​ 0.3 Total current liabilities ​ ​ 47.9 ​ ​ (11.5) ​ ​ — ​ ​ 36.4 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating lease liabilities ​ ​ 3.4 ​ ​ — ​ ​ — ​ ​ 3.4 Other liabilities ​ ​ 2.8 ​ ​ — ​ ​ — ​ ​ 2.8 Liabilities subject to compromise ​ ​ 488.8 ​ ​ (488.8) (g) ​ — ​ ​ — Total liabilities ​ ​ 542.9 ​ ​ (500.3) ​ ​ — ​ ​ 42.6 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stockholders’ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common stock - Predecessor ​ ​ 36.4 ​ ​ (36.4) (h) ​ — ​ ​ — Additional paid-in capital - Predecessor ​ ​ 4,392.9 ​ ​ (4,392.9) (h) ​ — ​ ​ — Common stock - Successor ​ ​ — ​ ​ 0.1 (i) ​ — ​ ​ 0.1 Additional paid-in capital - Successor ​ ​ — ​ ​ 279.5 (i) ​ — ​ ​ 279.5 Accumulated deficit ​ ​ (4,530.1) ​ ​ 4,601.9 (j) ​ (71.8) (p) ​ — Total stockholders’ (deficit) equity ​ ​ (100.8) ​ ​ 452.2 ​ ​ (71.8) ​ ​ 279.6 Total liabilities and stockholders’ (deficit) equity ​ $ 442.1 ​ $ (48.1) ​ $ (71.8) ​ $ 322.2 ​ ​ Reorganization Adjustments a) Reflects the net cash activities that occurred on the Effective Date.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 4 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation We prepared the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements include the accounts of the Company and all majority-owned domestic and foreign subsidiaries. Investments over which we have the ability to exercise significant influence over operating and financial policies, but do not hold a controlling interest, are accounted for using the equity method of accounting. All significant intercompany accounts and transactions have been eliminated in consolidation. There were no items of other comprehensive income in the periods presented. Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, related revenues and expenses, and the disclosure of gain and loss contingencies at the date of the financial statements and during the periods presented. We base these estimates on historical results and various other assumptions believed to be reasonable, all of which form the basis for making estimates concerning the carrying values of assets and liabilities that are not readily available from other sources. Actual results could differ materially from those estimates. Fresh Start Accounting Upon emergence from bankruptcy the Company adopted fresh start accounting. Refer to Note 3 – Fresh Start Accounting for further details. Cash and Cash Equivalents Cash equivalents include only investments with an original maturity of three months or less. We occasionally hold cash deposits in financial institutions that exceed federally insured limits. We monitor the credit ratings and our concentration of risk with these financial institutions on a continuing basis to safeguard our cash deposits. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at their invoiced amounts or amounts for which we have a right to invoice based on services completed. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments Inventories Inventories primarily consist of maintenance parts that are used to service our hydraulic fracturing equipment but will also include proppants and chemicals that are used to provide hydraulic fracturing services. Inventory held as of our emergence date was remeasured to fair value. Subsequent to our emergence, inventories are stated at the lower of cost or net realizable value. The cost basis of our inventories is based on the average cost method and includes in-bound freight costs. As necessary, we record an adjustment to decrease the value of slow moving and obsolete inventory to its net realizable value. To determine the adjustment amount, we regularly review inventory quantities on hand and compare them to estimates of future product demand, market conditions, production requirements and technological developments. Restricted Cash The Company had $12.7 million and zero restricted cash at December 31, 2020 and 2019, respectively. At December 31, 2020 the company’s restricted cash included unsettled escrow fees related to our bankruptcy emergence and cash used as collateral for other banking products. Property, Plant, and Equipment Property, plant, and equipment held as of our emergence date was remeasured to fair value and depreciated over the estimated remaining useful lives of individual assets. Property, plant, and equipment purchased subsequent to our emergence date is stated at cost less accumulated depreciation, which is generally provided by using the straight-line method over the estimated useful lives of the individual assets. We manufacture and refurbish equipment used in our hydraulic fracturing operations and the cost of this equipment, which includes direct and indirect manufacturing costs, is capitalized and carried as construction-in-progress until it is completed. Expenditures for renewals and betterments that extend the lives of our service equipment, which includes the replacement of significant components of service equipment, are capitalized and depreciated. Other repairs and maintenance costs are expensed as incurred. We capitalize qualifying costs related to the acquisition or development of internal-use software. Capitalization of costs begins after the conceptual formulation stage has been completed. Capitalized costs are amortized over the estimated useful life of the software, which ranges between three Leases We determine if a contract contains a lease at inception. We lease certain administrative offices, sales offices, and operational facilities. We also lease some service equipment and light duty vehicles. These leases have remaining lease terms of 6 years or less. Some leases contain options to extend the leases, and some include options to terminate the leases. We do not include renewal or termination options in our assessment of the lease terms unless extension or termination for certain leases is deemed to be reasonably certain. Lease agreements with lease and non-lease components are generally accounted for as a single lease component. Operating lease assets and liabilities are recognized at the lease commencement date, which is the date we take possession of the property. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are valued based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we estimate incremental secured borrowing rates corresponding to the lease term including reasonably certain renewal periods. We estimate this rate based on prevailing financial market conditions, credit analysis, and management judgment. Our leases typically contain rent escalations over the lease term. We recognize expense for these leases on a straight-line basis over the lease term. Additionally, tenant incentives used to fund leasehold improvements are recognized when earned and reduce our right-of-use asset related to the lease. These are amortized through the operating lease asset as reductions of expense over the lease term. We provide residual value guarantees for our leases of light-duty vehicles and certain service equipment. No amounts related to these residual value guarantees have been deemed probable and included in the lease liabilities on our consolidated balance sheet; however, if the value for all of the vehicles was zero and if we cancelled these leases at December 31, 2020, we would be required to pay a total of $5.6 million in residual value guarantees. Intangible Assets We have historically acquired indefinite-lived intangible assets related to business acquisitions. Intangible assets with indefinite lives are not amortized. The amount of indefinite-lived intangible assets recorded in our consolidated balance sheets for December 31, 2020, was $7.4 million, of which 6.0 million related to our tradename and $1.4 million related to our developed technology. At December 31, 2019, the amount of indefinite-lived intangible assets recorded in our consolidated balance sheets was $29.5 million which related to our tradename. On November 19, 2020, upon emergence from Chapter 11 bankruptcy our intangible assets were identified and valued at fair value and a finite life was assigned to our developed technology. We amortize this intangible asset with a finite life on a straight-line basis over a period of three years which the asset is expected to contribute to our future cash flows. Impairment of Long-Lived Assets and Intangible Assets Long-lived assets, such as property, plant, equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Recoverability is assessed based on the undiscounted future cash flows generated by the asset or asset group. If the carrying amount of an asset or asset group is not recoverable, we recognize an impairment loss equal to the amount by which the carrying amount exceeds fair value. We estimate fair value based on the income, market, or cost valuation techniques. Intangible assets with indefinite lives are reviewed at least annually for impairment, and in interim periods if certain events occur indicating that the carrying value of intangible assets may be impaired. We estimate fair values utilizing valuation methods such as discounted cash flows and comparable market valuations. We perform our annual impairment tests at the beginning of the fourth quarter. Equity Method Investments Investments in which we have the ability to exercise significant influence, but not control, are accounted for pursuant to the equity method of accounting. We recognize our proportionate share of earnings or losses of our international affiliates three months after they occur. When events and circumstances warrant, investments accounted for under the equity method of accounting are evaluated for impairment. An impairment charge is recorded whenever a decline in value of an investment below its carrying amount is determined to be other-than-temporary. Income Taxes Income taxes are accounted for using the asset and liability method. Deferred taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The effect on deferred taxes for a change in tax rates is recognized in earnings in the period that includes the enactment date. We recognize future tax benefits to the extent that such benefits are more likely than not to be realized. We record a valuation allowance to reduce the value of a deferred tax asset if based on the consideration of all available evidence, it is more likely than not that all or some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. We evaluate our deferred income taxes quarterly to determine if a valuation allowance is required by considering all available evidence, including historical and projected taxable income and tax planning strategies. We will adjust a previously established valuation allowance if we change our assessment of the amount of deferred income tax asset that is more likely than not to be realized. We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Revenue Recognition The Company contracts with its customers to perform hydraulic fracturing services on one or more oil or natural gas wells. Under these arrangements, we satisfy our performance obligations as services are rendered, which is generally upon the completion of a fracturing stage. We typically complete one or more stages per day. A stage is considered complete when we have met the specifications set forth by the customer, at which time we have the right to invoice the customer and the customer is obligated to pay us for the services rendered. The price for our services typically includes an equipment charge and product charges for proppant, chemicals and other products consumed during the course of providing our services. Payment terms average approximately two months from the date a stage or well is completed. All consideration owed to us for services performed during a period is fixed and our right to receive it is unconditional. We also contract with some customers to provide them with the exclusive use of a fracturing fleet for a period of time. Our customers can generally terminate these contracts with less than 90 days’ notice. We satisfy our performance obligation as services are rendered, which is based on the passage of time rather than the completion of a stage. Under these arrangements, we have the right to receive consideration from a customer even if circumstances outside of our control prevent us from performing our work. All consideration owed to us for services performed during a period is fixed and our right to receive it is unconditional. Pricing for our services for all contracts is frequently negotiated with our customers and is based on prevailing market rates during each reporting period. The amounts we invoice our customers for services performed during a period are directly related to the value received by the customers for the period. There is no inherent uncertainty to the amount of consideration we will receive for services performed during a period and no judgment is required to allocate a portion of the transaction price to a future period. Accordingly, we are not required to identify any unsatisfied performance obligations nor attribute any revenue to them. During the periods presented we acted as a principal, rather than as an agent, for all of the goods and services that we provided to our customers; our customer arrangements did not include obligations for refunds or warranties of our work; our revenue does not include sales taxes collected from our customers; and we did not incur incremental costs to obtain or fulfill contracts with our customers. To comply with the FASB disclosure objective, we are required to disaggregate our revenue into categories if it will provide an enhanced understanding of how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors. To evaluate an appropriate level of disaggregation of revenue, we considered the following aspects of our business: ● We provide a single service to our customers. ● We only generate revenue in the U.S. onshore market. ● We have a homogeneous customer base, which is comprised of large oil and gas exploration companies. ● We provide our service over a short period of time. ● We do not disaggregate our revenue into categories for any external communications or to make resource allocation decisions. ● We do not have separate operating segments. Based on the above factors, we concluded that no additional disaggregation of revenue was necessary or meaningful to help depict the nature, amount, timing and uncertainty of our revenues and cash flows. Unconditional Purchase Obligations We have historically entered into supply arrangements, primarily for sand, with our vendors that contain unconditional purchase obligations. These represent obligations to transfer funds in the future for fixed or minimum quantities of goods at fixed or minimum prices. We enter into these unconditional purchase obligation arrangements in the normal course of business to ensure that adequate levels of sourced product are available to us. We currently do not have any such supply agreements. To account for these arrangements, we must monitor whether we may be required to make a minimum payment to a vendor in a future period because our projected inventory purchases may not satisfy our minimum commitments. Stock-Based Compensation We measure all employee stock-based compensation awards using a fair value method and record this cost in the consolidated financial statements. Our stock-based compensation relates to restricted stock units issued to our employees. On the date that an equity-classified award is granted, we determine the fair value of the award and recognize the compensation cost over the requisite service period, which typically is the period over which the award vests. For equity-classified awards with graded vesting based solely on the satisfaction of a service condition, we recognize compensation cost as a single award on a straight-line basis. We account for forfeited awards as forfeitures occur, which results in a reversal of stock-based compensation cost previously recognized up to the date of the forfeiture. For stock-based awards with performance conditions that affect vesting, we only recognize compensation cost when it is probable that the performance conditions will be met. Fair Value Measurements Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: ● Level One: The use of quoted prices in active markets for identical financial instruments. ● Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data. ● Level Three: The use of significant unobservable inputs that typically require the use of management’s estimates of assumptions that market participants would use in pricing. Money market funds, classified as cash and cash equivalents, are the only financial instruments that are measured and recorded at fair value on the Company’s balance sheets. The following table presents money market funds at their level within the fair value hierarchy. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In millions) ​ Total ​ Level 1 ​ Level 2 ​ Level 3 December 31, 2020 (Successor) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ $ 59.6 ​ $ 59.6 ​ $ — ​ $ — December 31, 2019 (Predecessor) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ $ 193.6 ​ $ 193.6 ​ $ — ​ $ — ​ Reclassifications All inventory write-downs have been reclassified from costs of revenue to impairments and other charges on the statements of operations to conform to current year presentation.

New Accounting Standards Updates In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases embedded leases and we identified the key terms that were necessary for us to calculate the right-of-use asset and lease liability. These consolidated financial statements have been prepared in accordance with the new ASU utilizing the modified retrospective transition method, which resulted in the recording of operating lease liabilities of approximately $38 million as of January 1, 2019 on our consolidated balance sheet with an immaterial effect on our consolidated statement of stockholders’ equity (deficit) and no related effect on our consolidated statement of operations.

Successor Revolving Credit Facility On November 19, 2020, The Successor Company entered into a $40 million revolving credit facility, with an initial maturity date of November 19, 2023, with Wells Fargo, N.A. LIBOR borrowings under the credit facility bear interest at the greater of LIBOR or 0.75% plus a margin of 2.25% to 2.50% per annum, depending on facility utilization. Base rate loans are also available at our option. The credit facility includes a $15 million sub-limit for outstanding letters of credit which would reduce the amount available under the facility. We also pay a commitment fee on the unused amount of the facility of 0.375% per annum, depending on facility utilization. The obligations under the credit facility are secured by substantially all of our assets, including our working capital and equipment. The maximum availability of credit under the credit facility is limited at any time to the lesser of $40 million or a borrowing base. The borrowing base is based on percentages of eligible accounts receivable and is subject to certain reserves. In an event of default or if the amount available under the credit facility is less than either 12.5% of our maximum availability or $5.0 million, we will be required to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0. If at any time borrowings and letters of credit issued under the credit facility exceed the borrowing base, we will be required to repay an amount equal to such excess. The credit facility contains covenants that could, in certain circumstances, limit our ability to issue additional debt, repurchase or pay dividends on our common stock, sell substantially all of our assets, make certain investments, or enter into certain other transactions. We were in compliance with all of the covenants in the credit facility at December 31, 2020. As of December 31, 2020, the borrowing base was $17.2 million and therefore our maximum availability under the credit facility was $17.2 million. As of December 31, 2020, there were no borrowings outstanding under the credit facility, and letters of credit totaling $4.0 million were issued, resulting in $13.2 million of availability under the credit facility. Predecessor 2021 Term Loan On April 16, 2014, the Predecessor Company entered into a $550 million term loan, which matures on April 16, 2021 (“Term Loan”), with a group of lenders with Wells Fargo Bank, N.A., as administrative agent. The Term Loan bears interest at a three-month London Interbank Offered Rate (“LIBOR”) plus a margin of 4.75% per annum, with a 1.00% LIBOR floor. Interest is payable on interest rate reset dates, which is generally monthly. The Term Loan was issued at a discount of $2.7 million for aggregate consideration of $547.3 million and resulted in net proceeds to the Company of $540.0 million after debt issuance costs of $7.3 million. In 2020, the Predecessor Company repaid $22.6 million of aggregate principal amount of Term Loan. We recognized a gain on debt extinguishment of $2.0 million. In 2019, we repaid $31.0 million of aggregate principal amount of Term Loan. We recognized a loss on debt extinguishment of $0.2 million. On November 19, 2020, upon emergence from Chapter 11 bankruptcy, the 2021 Term Loan was cancelled as part of the Plan. We were in compliance with all of the covenants in the Term Loan for all periods that the loan was outstanding until we filed for bankruptcy on September 22, 2020. Predecessor 2022 Senior Notes On April 16, 2014, the Predecessor Company completed an offering of $500 million of 6.25% senior secured notes due May 1, 2022, in a private offering to qualified institutional buyers (“2022 Senior Notes”). The credit facility was amended semiannually In 2020 and 2019, the Predecessor Company repurchased zero and $17.0 million, respectively, of aggregate principal amount of 2022 Senior Notes in the qualified institutional market. In 2019, the Predecessor Company recognized a gain on debt extinguishment of $1.4 million. In 2018, we repurchased $22.1 million of aggregate principal amount of 2022 Senior Notes in the qualified institutional market. We recognized a gain on debt extinguishment of $1.2 million. On November 19, 2020, upon emergence from Chapter 11 bankruptcy, the 2022 Senior Notes were cancelled as part of the Plan. We were in compliance with all of the covenants in the indenture governing our 2022 Senior Notes for all periods that these notes were outstanding, until be filed for bankruptcy on September 22, 2020. Predecessor 2020 Senior Floating Rate Notes On June 1, 2015, we completed an offering of $350 million of senior secured floating rate notes due June 15, 2020, in a private offering to qualified institutional buyers (“2020 Senior Notes”). The 2020 Senior Notes bore interest at a three-month LIBOR plus a margin of 7.5% per annum. In 2018, we repaid all $290.0 million of the remaining principal amount of 2020 Senior Notes. We recognized a loss on debt extinguishment of $8.3 million. We were in compliance with all of the covenants in the indenture governing our 2020 Senior Notes for all periods that these notes were outstanding. Predecessor Revolving Credit Facility On February 22, 2018, we entered into a $250 million revolving credit facility, with an initial maturity date of February 22, 2023, with a group of lenders with Wells Fargo, N.A., as administrative agent. As part of the Chapter 11 filing our revolving credit facility was terminated in the third quarter of 2020. Prior to its termination, the maximum availability of credit under our revolving credit facility was limited at any time to the lesser of $100 million or a borrowing base. The credit facility was amended in August 2020, which among other things, reduced the maximum availability under the credit facility from $250 million to $100 million. The borrowing base was based on percentages of eligible accounts receivable and was subject to certain reserves. If at any time borrowings and letters of credit issued under the credit facility exceeded the borrowing base, we would be required to repay an amount equal to such excess. During 2020, the Predecessor Company had no borrowings drawn under the credit facility, and certain letters of credit were issued. At September 30, 2020, we had replaced these letters of credit with cash collateralized letters of credit.

STOCKHOLDERS' EQUITY (DEFICIT)	NOTE 8 — STOCKHOLDERS’ EQUITY (DEFICIT) Common and Preferred Stock On November 19, 2020, upon emergence from Chapter 11 bankruptcy, all existing shares of Predecessor common stock were cancelled, and the Successor Company issued approximately 13.7 million shares of Class A common stock and 0.3 million shares of Class B common stock. On November 19, 2020, upon emergence from Chapter 11 bankruptcy, the Successor Company filed an Amended and Restated Certificate of Incorporation with the Delaware Secretary of State. Pursuant to the Certificate of Incorporation, the authorized capital stock of FTSI consists of 49,000,000 shares of New Class A Common Stock and 1,000,000 shares of New Class B Common Stock and 5,000,000 shares of Preferred Stock, par value $0.01 per share (the “Preferred Stock”). The New Class B Common Stock is identical to the New Class A Common Stock, except that such New Class B Common Stock shall not be listed for trading on any national securities exchange or NASDAQ, nor shall it be listed over-the-counter. Upon the written request of a holder of New Class B Common Stock, and in compliance with the provisions of the Certification of Incorporation, the shares of New Class B Common Stock shall be exchangeable into the same number of shares of New Class A Common Stock. Shares of Preferred Stock may be issued in one or more classes or series from time to time, with each such class or series to consist of such number of shares and to have such designations, powers, preferences and relative, participating, optional or other rights, if any, and the qualifications, limitations or restrictions thereof, if any, with respect to each such class or series as shall be stated in the resolution or resolutions providing for the issuance of such class or series adopted by the Board. 2020 Reverse Stock Split In May 2020, the Predecessor Company’s board of directors (our “Board”) approved a reverse stock split of the Company’s issued and outstanding common stock on a one Share repurchase program In May 2019, the Predecessor Company’s board of directors approved an authorization for a total share repurchase of up to $100 million of the Predecessor Company’s common stock to be executed through open market or private transactions. The authorization expired on May 14, 2020. In 2019 we repurchased approximately 3.0 million shares of common stock at an average price of $3.34 per share for a total of $9.9 million. Initial Public Offering of Common Stock The Predecessor Company completed an initial public offering (“IPO”) of 22.4 million shares of common stock at a price to the public of $18.00 per share, of which 18.1 million shares were sold by the Company and 4.3 million shares were sold by one of our stockholders, a subsidiary of Chesapeake Energy Corporation. The shares began trading on The New York Stock Exchange on February 2, 2018, under the ticker symbol “FTSI.” The Predecessor Company received net proceeds from the offering of $303.0 million, after offering costs. We used the net proceeds from the offering for general corporate purposes, primarily debt repayments. The Predecessor Company did not receive any proceeds from the offering of shares by the selling stockholder. IPO Reverse Stock Split In connection with the IPO, the Predecessor Company amended and restated our certificate of incorporation to effect a 69.258777:1 reverse stock split of our common stock. Convertible Preferred Stock In September 2012, the Predecessor Company issued and sold 350,000 shares of Series A convertible preferred stock, par value $0.01 per share (the “Preferred Stock”), to certain of our then existing common stockholders. The Preferred Stock was sold for aggregate consideration of $350 million, and resulted in net proceeds to the Predecessor Company of $349.8 million after the payment of $0.2 million in issuance costs. Each share of Preferred Stock was convertible into 2,573 shares of our common stock, subject to adjustment upon the occurrence of specified events set forth under terms of the Preferred Stock. The Preferred Stock was redeemable at the Predecessor Company’s option at any time after all of our debt was repaid. The redemption price per share was an amount in cash equal to the original price per share of the Preferred Stock, plus such additional amount as would give the holder an after-tax internal rate of return for investment in the Preferred Stock of 25% per annum (the “Accreted Amount”). At December 31, 2017, the Accreted Amount of the Preferred Stock was estimated to be $1,132.7 million. The Preferred Stock was mandatorily convertible into shares of our common stock in connection with an initial public offering of our common stock if both of the following conditions were met (a “Qualified IPO”): ● Aggregate proceeds to the Predecessor Company were at least $250 million; and ● The split-adjusted initial offering price to the public was not less than $1.50 per share. In connection with a Qualified IPO, each share of Preferred Stock would be convertible into the number of shares of common stock that had a market value (based on the initial offering price to the public) equal to the Accreted Amount. The Preferred Stock was mandatorily redeemable for cash upon a change of control, provided that all of our debt had been repaid. Each share of Preferred Stock would be redeemed for an amount in cash equal to the higher of: ● The Accreted Amount; or ● The original purchase price of the Preferred Stock plus an amount equal to 20% of the then outstanding equity value of the Predecessor Company divided by the number of Preferred Stock shares then outstanding. The Preferred Stock ranked senior to our common stock with respect to dividend rights and distribution rights in the event of any liquidation, winding-up or dissolution of the Predecessor Company. The amount that each share of Preferred Stock was entitled to in liquidation is equal to the Accreted Amount. The holders of the Preferred Stock were also common stockholders of the Predecessor Company and, prior to the completion of our initial public offering, collectively appointed 100% of our board of directors. Therefore, the Preferred Stock holders could have directed the Predecessor Company to redeem the Preferred Stock at any time after all of our debt had been repaid; however, we did not consider this to be probable for any of the periods the Preferred Stock was outstanding due to the amount of debt outstanding at that time. Therefore, we did not record any accretion of the Preferred Stock in our consolidated financial statements. In connection with the IPO, a number of shares of our Preferred Stock converted into common stock at the rate of 155.944841 shares of common stock per each share of Preferred Stock. All remaining shares of Preferred Stock were canceled. We refer to this conversion and the cancelation together as the recapitalization of the Preferred Stock. The conversion rate of the Preferred Stock and shares canceled were calculated so that following the recapitalization, stockholders that did not own Preferred Stock would own 7% of our common stock prior to the IPO. The recapitalization of all outstanding shares of our Preferred Stock resulted in 39.4 million new shares of common stock.

STOCK-BASED COMPENSATION
STOCK-BASED COMPENSATION	NOTE 9 — STOCK-BASED COMPENSATION Predecessor 2014 Long-Term Incentive Plan In 2014, our stockholders approved the 2014 Long-Term Incentive Plan (“2014 LTIP”). The 2014 LTIP authorized the grant of up to 55 million restricted stock units (“RSUs”) to salaried employees of the Company, as determined by the compensation committee of the board of directors. This plan originally was set to expire on March 3, 2024. In February 2018, we completed an IPO of our common stock. This transaction qualified as the final vesting condition for these RSUs. The compensation expense recognized in 2018 for the stock-settled RSUs was $2.0 million. The compensation expense recognized in 2018 for the cash-settled RSUs was $1.7 million. The Company elected to settle the stock-settled RSUs in cash. The 2014 LTIP was terminated after the payout of the RSUs. Predecessor 2018 Equity and Incentive Compensation Plan Our board of directors and stockholders adopted the 2018 Equity and Incentive Compensation Plan (“2018 Plan”) to attract and retain officers, employees, directors, consultants and other key personnel and to provide those persons incentives and awards for performance. The 2018 Plan originally allocated 2.8 million shares of common stock in the form of incentive stock options, non-qualified stock options, restricted stock, restricted stock units (“RSUs”), stock appreciation rights, or other stock-based awards. In 2019 our board of directors and stockholders amended and restated the 2018 Plan to increase the number of shares available for issuance by 3.6 million shares. Any shares that become available as a result of forfeiture, cancelation, expiration or cash settlement of an award are allowed to be granted again at a future date under the 2018 Plan. This plan originally was set to expire on February 1, 2028, but was terminated upon emergence from bankruptcy on November 19, 2020. RSUs are generally valued at the market price of a share of our common stock on the date of grant. Awards granted to employees generally vest over a three The following table summarizes the January 1 through November 19, 2020 transactions related to the RSUs granted under the Predecessor Company’s 2018 Plan. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted- ​ ​ Number ​ Average ​ ​ of Units ​ Grant-Date ​ ​ (In thousands) ​ Fair Value Unvested balance at January 1, 2020 ​ 179 ​ $ 209.23 Granted ​ — ​ ​ — Vested ​ (174) ​ ​ 209.11 Forfeited ​ (5) ​ ​ 213.74 Unvested balance at November 19, 2020 ​ — ​ $ — ​ Stock-based compensation expense for the Predecessor Company from January 1 through November 19, 2020 for these RSUs was $10.9 million and was $15.4 million in 2019.

The fair value of RSUs vested was $36.3 million and $15.8 million in 2020 and 2019, respectively. At November 19, 2020, there was zero total unrecognized compensation cost related to unvested RSUs. The total income tax benefit (expense) for all stock-based compensation was $(0.1) million and $1.2 million in 2020 and 2019 respectively; however, such benefit (expense) was substantially offset by the valuation allowance against our deferred tax assets. Successor 2020 Equity and Incentive Compensation Plan As part of the Plan, the Successor Company adopted the 2020 Equity and Incentive Compensation Plan (“2020 Plan”) to attract and retain officers, employees, directors, consultants and other key personnel and to provide those persons incentives and awards for performance. The 2020 Plan originally allocated 2,160 thousand shares of common stock in the form of incentive stock options, non-qualified stock options, restricted stock, restricted stock units (“RSUs”), stock appreciation rights, or other stock-based awards. As of December 31, 2020, up to approximately 1,080 thousand shares were available for future grants under this plan.

RETIREMENT PLAN
RETIREMENT PLAN	NOTE 10 — RETIREMENT PLAN We offer a 401(k) defined contribution retirement plan (“401(k) Plan”), which allows a participant to defer, by payroll deductions, from 0% to 100% of the participant’s annual compensation, limited to certain annual maximums set by the Internal Revenue Code. The 401(k) Plan has historically provided a discretionary matching contribution to each participant’s account. Company matching contributions to the 401(k) Plan are made in cash and were $2.5 million, and $4.1 million in 2019 and 2018, respectively. The Company suspended matching contributions in January 2020. As a result, there were zero company matching contributions to the 401

Supply Commitment Charges The Predecessor Company incurred supply commitment charges when our purchases of sand from certain suppliers are less than the minimum purchase commitments in our supply contracts. According to the accounting guidance for firm purchase commitments, future losses that are considered likely are also required to be recorded in the current period. The Predecessor Company recorded aggregate charges under these supply contracts of $9.1 million from January 1 through November 19, 2020, and $58.5 million and $19.2 million in 2019 and 2018, respectively. These charges relate to actual purchase shortfalls incurred, as well as forecasted losses expected to be incurred and settled in future periods. These purchase shortfalls are largely due to our customers choosing to procure their own sand, often from sand mines closer to their operating areas. In May 2019, the Predecessor Company restructured and amended our largest sand supply contract to reduce the total remaining commitment through 2024 by approximately $162 million. This reduced our annual commitment from $47.9 million to $21.0 million from 2019 through 2024. Due to the terms of the amended agreement and our estimated future purchases under this contract, we determined that we would not be able to satisfy $11.0 million of the $21.0 million annual commitment with sand purchases for the last five years of the contract. Therefore, in connection with this amendment, we recorded a supply commitment charge of $55.0 million in the first quarter of 2019 to accelerate these purchase shortfalls. After recording the $55.0 million supply commitment charge in the first quarter of 2019, the amount of accrued supply commitment charges for future periods that was recognized on our consolidated balance sheet at March 31, 2019 was $66.0 million. We paid $11.0 million of this amount in the second quarter of 2019 and we expected to pay the remaining $55.0 million in annual installments of $11.0 million from January 2020 through January 2024. The remaining amount of the 2019 charges represent revised estimates of our purchase shortfalls under this contract for 2019. The Company terminated all sand supply contracts upon emergence from bankruptcy. Any amounts due as outlined in the Plan were paid upon emergence and the Company does not expect any future commitment related to these Predecessor contracts. Fleet Capacity Reduction In the fourth quarter of 2019, the Predecessor Company disposed of certain idle equipment where we believed there was no expectation of future use. The equipment we selected for disposal was comprised primarily of hydraulic fracturing pumps that were substantially depreciated. Certain hydraulic fracturing components, such as engines and transmissions that we believe to have remaining useful lives, will be removed prior to disposing of the equipment and used in our maintenance and repair activities for our remaining fleets. These disposals reduced our capacity of equipment from 34 total fleets to 28 total fleets. The amount of proceeds we received from these disposals was not significant. We recorded an asset impairment of $4.2 million in the third quarter of 2019 in connection with these disposals. Discontinued Wireline Operations In May 2019, the Predecessor Company discontinued our wireline operations due to financial underperformance resulting from market conditions. As a result of this decision, we recorded an asset impairment of $2.8 million and an inventory write-down of $1.4 million in the first quarter of 2019 to adjust these assets to their estimated fair market values and net realizable values, respectively. We sold substantially all of these assets in 2019 and received net proceeds of approximately $3.7 million. Other Impairments In the second quarter of 2019, the Predecessor Company recorded $2.7 million of impairments for certain land and buildings that we no longer use. We are closely monitoring current industry conditions and future expectations. If industry conditions decline, we may be subject to impairments of long-lived assets or intangible assets in future periods.

States have different income tax rates and therefore the weighted-average state tax rate that we apply to our taxable and deductible temporary differences and net operating loss carryforwards can also change over time. The resulting effects of state apportionment on our deferred tax assets and deferred tax liabilities are recognized to reflect the future impact of these changes and affects our overall effective tax rate; however, these changes are currently offset by corresponding changes in our valuation allowance. In March 2020, the President of the United States signed into law the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The CARES Act includes several U.S. income tax provisions related to, among other things, net operating loss carrybacks, alternative minimum tax credits, modifications to the net interest deduction limitations, and technical amendments regarding the income tax depreciation of qualified improvement property placed in service after December 31, 2017. The CARES Act is not expected to have a material impact on the Company’s financial results. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are presented below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Successor ​ ​ Predecessor ​ ​ December 31, ​ ​ December 31, (In millions) ​ 2020 ​ ​ 2019 Deferred tax assets: ​ ​ ​ ​ ​ ​ ​ Goodwill and intangible assets ​ $ 19.5 ​ ​ $ 257.5 Federal net operating loss carryforwards ​ ​ 65.6 ​ ​ ​ 359.3 State net operating loss carryforwards, net of federal benefit ​ ​ 2.6 ​ ​ ​ 43.9 Interest carryforward ​ ​ 9.6 ​ ​ ​ 0.1 Accrued liabilities ​ ​ 0.8 ​ ​ ​ 13.7 Operating lease liability ​ ​ 1.4 ​ ​ ​ 6.2 Stock-based compensation ​ ​ 0.1 ​ ​ ​ 2.2 Other ​ ​ 0.8 ​ ​ ​ 2.2 Gross deferred tax assets ​ ​ 100.4 ​ ​ ​ 685.1 Valuation allowance ​ ​ (99.3) ​ ​ ​ (671.7) Total deferred tax assets ​ ​ 1.1 ​ ​ ​ 13.4 ​ ​ ​ ​ ​ ​ ​ ​ Deferred tax liabilities: ​ ​ ​ ​ ​ ​ ​ Property, plant, and equipment ​ ​ 0.1 ​ ​ ​ 7.6 Operating lease right-of-use assets ​ ​ 1.0 ​ ​ ​ 5.8 Total deferred tax liabilities ​ ​ 1.1 ​ ​ ​ 13.4 ​ ​ ​ ​ ​ ​ ​ ​ Net deferred tax asset ​ $ — ​ ​ $ — ​ Because of our valuation allowance, our net deferred tax assets are zero and no deferred tax assets or liabilities are included in the consolidated balance sheets. At December 31, 2020, our gross federal net operating loss carryforwards were approximately $312.5 million, of which $40.1 million will expire on various dates between 2032 and 2036 with the remaining losses carried forward indefinitely. Our gross state net operating loss carryforwards were approximately $54.0 million, of which $16.4 million will expire at various dates between 2021-2040 with the remaining carried forward indefinitely On August 22, 2020, we entered into a restructuring support agreement with certain of our note holders and lenders (collectively the “consenting creditors”). The restructuring support agreement included a cash premium payable to the consenting creditors. The cash premium was considered a significant modification of the notes and term loan for tax purposes. Under the Internal Revenue Code (IRC), the significant modification created cancellation of debt (COD) income to the Company, part of which is excluded from taxable income due to special rules under IRC Section 108. However, the excluded amount does reduce the Company’s NOL. IRC Section 382 provides an annual limitation with respect to the ability of a corporation to utilize its tax attributes, as well as certain built-in-losses, against future U.S. taxable income in the event of a change in ownership. The Company’s emergence from Chapter 11 bankruptcy proceedings is considered a change in ownership for purposes of IRC Section 382. The limitation under the IRC is based on the value of the corporation as of the emergence date. As a result of the Section 382 “ownership change”, our pre-Chapter 11 federal NOLs were significantly reduced to approximately At each reporting date, we consider all available positive and negative evidence to evaluate whether our deferred tax assets are more likely than not to be realized. The primary positive evidence we noted was: ● Cumulative income before income taxes for the three years ended December 31, 2020, was $151.3 million. The primary negative evidence we noted was: ● Our loss before income taxes was $71.5 million in 2019, and $24.2 million and $13.4 million for the Predecessor and Successor periods of 2020, respectively. ● We filed for bankruptcy in 2020. ● The forecasts of our results and the consensus forecasts of the hydraulic fracturing industry have been historically volatile due to the up-and-down cycles experienced by the industry. ● We do not have prudent and feasible tax-planning strategies available to us to realize deferred tax assets. Notwithstanding the three-year cumulative income, we concluded that a full valuation allowance is still required at December 31, 2020. We based this conclusion on the positive and negative evidence discussed above. If we generate income before income taxes in future periods and if our forecasts become more accurate due to the cycles of the hydraulic fracturing industry becoming less significant, we may be able to recognize a portion of our net deferred tax assets in future periods. We will adjust the valuation allowance based on our evaluation of new information as it becomes available and new circumstances as they occur. At December 31, 2020 and 2019, we had no liability for uncertain tax positions. We recognize interest and penalties related to UTBs on the income tax expense line in the accompanying consolidated statement of operations. FTS International, Inc. and its U.S. subsidiaries join in the filing of a U.S. federal consolidated income tax return. We do not currently have significant operations or undistributed earnings in foreign jurisdictions. Our income tax returns are currently subject to examination in federal and state jurisdictions primarily for tax years from 2016 through 2019.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2020
Policy Text Blocks
Basis of Presentation	Basis of Presentation We prepared the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements include the accounts of the Company and all majority-owned domestic and foreign subsidiaries. Investments over which we have the ability to exercise significant influence over operating and financial policies, but do not hold a controlling interest, are accounted for using the equity method of accounting. All significant intercompany accounts and transactions have been eliminated in consolidation. There were no items of other comprehensive income in the periods presented.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, related revenues and expenses, and the disclosure of gain and loss contingencies at the date of the financial statements and during the periods presented. We base these estimates on historical results and various other assumptions believed to be reasonable, all of which form the basis for making estimates concerning the carrying values of assets and liabilities that are not readily available from other sources. Actual results could differ materially from those estimates.
Fresh Start Accounting	Fresh Start Accounting Upon emergence from bankruptcy the Company adopted fresh start accounting. Refer to Note 3 – Fresh Start Accounting for further details.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents include only investments with an original maturity of three months or less. We occasionally hold cash deposits in financial institutions that exceed federally insured limits. We monitor the credit ratings and our concentration of risk with these financial institutions on a continuing basis to safeguard our cash deposits.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at their invoiced amounts or amounts for which we have a right to invoice based on services completed. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments
Inventories	Inventories Inventories primarily consist of maintenance parts that are used to service our hydraulic fracturing equipment but will also include proppants and chemicals that are used to provide hydraulic fracturing services. Inventory held as of our emergence date was remeasured to fair value. Subsequent to our emergence, inventories are stated at the lower of cost or net realizable value. The cost basis of our inventories is based on the average cost method and includes in-bound freight costs. As necessary, we record an adjustment to decrease the value of slow moving and obsolete inventory to its net realizable value. To determine the adjustment amount, we regularly review inventory quantities on hand and compare them to estimates of future product demand, market conditions, production requirements and technological developments.
Restricted Cash	Restricted Cash The Company had $12.7 million and zero restricted cash at December 31, 2020 and 2019, respectively. At December 31, 2020 the company’s restricted cash included unsettled escrow fees related to our bankruptcy emergence and cash used as collateral for other banking products.
Property, Plant, and Equipment	Property, Plant, and Equipment Property, plant, and equipment held as of our emergence date was remeasured to fair value and depreciated over the estimated remaining useful lives of individual assets. Property, plant, and equipment purchased subsequent to our emergence date is stated at cost less accumulated depreciation, which is generally provided by using the straight-line method over the estimated useful lives of the individual assets. We manufacture and refurbish equipment used in our hydraulic fracturing operations and the cost of this equipment, which includes direct and indirect manufacturing costs, is capitalized and carried as construction-in-progress until it is completed. Expenditures for renewals and betterments that extend the lives of our service equipment, which includes the replacement of significant components of service equipment, are capitalized and depreciated. Other repairs and maintenance costs are expensed as incurred. We capitalize qualifying costs related to the acquisition or development of internal-use software. Capitalization of costs begins after the conceptual formulation stage has been completed. Capitalized costs are amortized over the estimated useful life of the software, which ranges between three
Leases	Leases We determine if a contract contains a lease at inception. We lease certain administrative offices, sales offices, and operational facilities. We also lease some service equipment and light duty vehicles. These leases have remaining lease terms of 6 years or less. Some leases contain options to extend the leases, and some include options to terminate the leases. We do not include renewal or termination options in our assessment of the lease terms unless extension or termination for certain leases is deemed to be reasonably certain. Lease agreements with lease and non-lease components are generally accounted for as a single lease component. Operating lease assets and liabilities are recognized at the lease commencement date, which is the date we take possession of the property. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are valued based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we estimate incremental secured borrowing rates corresponding to the lease term including reasonably certain renewal periods. We estimate this rate based on prevailing financial market conditions, credit analysis, and management judgment. Our leases typically contain rent escalations over the lease term. We recognize expense for these leases on a straight-line basis over the lease term. Additionally, tenant incentives used to fund leasehold improvements are recognized when earned and reduce our right-of-use asset related to the lease. These are amortized through the operating lease asset as reductions of expense over the lease term. We provide residual value guarantees for our leases of light-duty vehicles and certain service equipment. No amounts related to these residual value guarantees have been deemed probable and included in the lease liabilities on our consolidated balance sheet; however, if the value for all of the vehicles was zero and if we cancelled these leases at December 31, 2020, we would be required to pay a total of $5.6 million in residual value guarantees.
Intangible Assets	Intangible Assets We have historically acquired indefinite-lived intangible assets related to business acquisitions. Intangible assets with indefinite lives are not amortized. The amount of indefinite-lived intangible assets recorded in our consolidated balance sheets for December 31, 2020, was $7.4 million, of which 6.0 million related to our tradename and $1.4 million related to our developed technology. At December 31, 2019, the amount of indefinite-lived intangible assets recorded in our consolidated balance sheets was $29.5 million which related to our tradename. On November 19, 2020, upon emergence from Chapter 11 bankruptcy our intangible assets were identified and valued at fair value and a finite life was assigned to our developed technology. We amortize this intangible asset with a finite life on a straight-line basis over a period of three years which the asset is expected to contribute to our future cash flows.
Impairment of Long-Lived Assets and Intangible Assets	Impairment of Long-Lived Assets and Intangible Assets Long-lived assets, such as property, plant, equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Recoverability is assessed based on the undiscounted future cash flows generated by the asset or asset group. If the carrying amount of an asset or asset group is not recoverable, we recognize an impairment loss equal to the amount by which the carrying amount exceeds fair value. We estimate fair value based on the income, market, or cost valuation techniques. Intangible assets with indefinite lives are reviewed at least annually for impairment, and in interim periods if certain events occur indicating that the carrying value of intangible assets may be impaired. We estimate fair values utilizing valuation methods such as discounted cash flows and comparable market valuations. We perform our annual impairment tests at the beginning of the fourth quarter.
Equity Method Investments	Equity Method Investments Investments in which we have the ability to exercise significant influence, but not control, are accounted for pursuant to the equity method of accounting. We recognize our proportionate share of earnings or losses of our international affiliates three months after they occur. When events and circumstances warrant, investments accounted for under the equity method of accounting are evaluated for impairment. An impairment charge is recorded whenever a decline in value of an investment below its carrying amount is determined to be other-than-temporary.
Income Taxes	Income Taxes Income taxes are accounted for using the asset and liability method. Deferred taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The effect on deferred taxes for a change in tax rates is recognized in earnings in the period that includes the enactment date. We recognize future tax benefits to the extent that such benefits are more likely than not to be realized. We record a valuation allowance to reduce the value of a deferred tax asset if based on the consideration of all available evidence, it is more likely than not that all or some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. We evaluate our deferred income taxes quarterly to determine if a valuation allowance is required by considering all available evidence, including historical and projected taxable income and tax planning strategies. We will adjust a previously established valuation allowance if we change our assessment of the amount of deferred income tax asset that is more likely than not to be realized. We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.
Revenue Recognition	Revenue Recognition The Company contracts with its customers to perform hydraulic fracturing services on one or more oil or natural gas wells. Under these arrangements, we satisfy our performance obligations as services are rendered, which is generally upon the completion of a fracturing stage. We typically complete one or more stages per day. A stage is considered complete when we have met the specifications set forth by the customer, at which time we have the right to invoice the customer and the customer is obligated to pay us for the services rendered. The price for our services typically includes an equipment charge and product charges for proppant, chemicals and other products consumed during the course of providing our services. Payment terms average approximately two months from the date a stage or well is completed. All consideration owed to us for services performed during a period is fixed and our right to receive it is unconditional. We also contract with some customers to provide them with the exclusive use of a fracturing fleet for a period of time. Our customers can generally terminate these contracts with less than 90 days’ notice. We satisfy our performance obligation as services are rendered, which is based on the passage of time rather than the completion of a stage. Under these arrangements, we have the right to receive consideration from a customer even if circumstances outside of our control prevent us from performing our work. All consideration owed to us for services performed during a period is fixed and our right to receive it is unconditional. Pricing for our services for all contracts is frequently negotiated with our customers and is based on prevailing market rates during each reporting period. The amounts we invoice our customers for services performed during a period are directly related to the value received by the customers for the period. There is no inherent uncertainty to the amount of consideration we will receive for services performed during a period and no judgment is required to allocate a portion of the transaction price to a future period. Accordingly, we are not required to identify any unsatisfied performance obligations nor attribute any revenue to them. During the periods presented we acted as a principal, rather than as an agent, for all of the goods and services that we provided to our customers; our customer arrangements did not include obligations for refunds or warranties of our work; our revenue does not include sales taxes collected from our customers; and we did not incur incremental costs to obtain or fulfill contracts with our customers. To comply with the FASB disclosure objective, we are required to disaggregate our revenue into categories if it will provide an enhanced understanding of how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors. To evaluate an appropriate level of disaggregation of revenue, we considered the following aspects of our business: ● We provide a single service to our customers. ● We only generate revenue in the U.S. onshore market. ● We have a homogeneous customer base, which is comprised of large oil and gas exploration companies. ● We provide our service over a short period of time. ● We do not disaggregate our revenue into categories for any external communications or to make resource allocation decisions. ● We do not have separate operating segments. Based on the above factors, we concluded that no additional disaggregation of revenue was necessary or meaningful to help depict the nature, amount, timing and uncertainty of our revenues and cash flows.
Unconditional Purchase Obligations	Unconditional Purchase Obligations We have historically entered into supply arrangements, primarily for sand, with our vendors that contain unconditional purchase obligations. These represent obligations to transfer funds in the future for fixed or minimum quantities of goods at fixed or minimum prices. We enter into these unconditional purchase obligation arrangements in the normal course of business to ensure that adequate levels of sourced product are available to us. We currently do not have any such supply agreements. To account for these arrangements, we must monitor whether we may be required to make a minimum payment to a vendor in a future period because our projected inventory purchases may not satisfy our minimum commitments.
Stock-Based Compensation	Stock-Based Compensation We measure all employee stock-based compensation awards using a fair value method and record this cost in the consolidated financial statements. Our stock-based compensation relates to restricted stock units issued to our employees. On the date that an equity-classified award is granted, we determine the fair value of the award and recognize the compensation cost over the requisite service period, which typically is the period over which the award vests. For equity-classified awards with graded vesting based solely on the satisfaction of a service condition, we recognize compensation cost as a single award on a straight-line basis. We account for forfeited awards as forfeitures occur, which results in a reversal of stock-based compensation cost previously recognized up to the date of the forfeiture. For stock-based awards with performance conditions that affect vesting, we only recognize compensation cost when it is probable that the performance conditions will be met.
Fair Value of Financial Instruments	Fair Value Measurements Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: ● Level One: The use of quoted prices in active markets for identical financial instruments. ● Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or other inputs that are observable in the market or can be corroborated by observable market data. ● Level Three: The use of significant unobservable inputs that typically require the use of management’s estimates of assumptions that market participants would use in pricing. Money market funds, classified as cash and cash equivalents, are the only financial instruments that are measured and recorded at fair value on the Company’s balance sheets. The following table presents money market funds at their level within the fair value hierarchy. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In millions) ​ Total ​ Level 1 ​ Level 2 ​ Level 3 December 31, 2020 (Successor) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ $ 59.6 ​ $ 59.6 ​ $ — ​ $ — December 31, 2019 (Predecessor) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ $ 193.6 ​ $ 193.6 ​ $ — ​ $ — ​
Reclassifications	Reclassifications All inventory write-downs have been reclassified from costs of revenue to impairments and other charges on the statements of operations to conform to current year presentation. This reclassification had no effect on operating income (loss) or net income (loss) as previously reported.
New Accounting Standards Updates	New Accounting Standards Updates In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases embedded leases and we identified the key terms that were necessary for us to calculate the right-of-use asset and lease liability. These consolidated financial statements have been prepared in accordance with the new ASU utilizing the modified retrospective transition method, which resulted in the recording of operating lease liabilities of approximately $38 million as of January 1, 2019 on our consolidated balance sheet with an immaterial effect on our consolidated statement of stockholders’ equity (deficit) and no related effect on our consolidated statement of operations.
