Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Business	Note A—Description of the Business BigBear.ai Holdings, Inc. ( “BigBear.ai” “Company” “AI” “ML” On December 7, 2021, the previously announced merger ( “Merger” “GigCapital4” “Agreement” “Merger Sub” “FPAs” The Merger is accounted for as a reverse recapitalization in which GigCapital4 is treated as the acquired company. For accounting purposes, the Merger is treated as the equivalent of BigBear.ai Holdings issuing equity for the net assets of GigCapital4 followed by a recapitalization. A reverse recapitalization does not result in a new basis of accounting, and the consolidated financial statements of the combined entity (BigBear.ai) represent the continuation of the consolidated financial statements of BigBear.ai Holdings in many respects. Immediately prior to the closing of the Merger, but following the consummation of GigCapital4’s domestication to a Delaware corporation, the authorized capital stock of GigCapital4 consisted of 501,000,000 shares, including (i) 500,000,000 shares of common stock and (ii) 1,000,000 shares of preferred stock. 135,566,227 shares of common stock and no shares of the preferred stock were outstanding as of December 31, 2021. At the effective time of the Merger, 100 units of BigBear.ai Holdings were cancelled and automatically deemed for all purposes to represent the Parent’s right to receive, in the aggregate, $75 million in cash and shares in GigCapital4, and Parent exchanged its 100 units of BigBear.ai Holdings for 105,000,000 shares of BigBear.ai’s common stock. In addition, 8,000,000 shares of PIPE financing were issued and 1,495,320 shares were issued to certain advisors.

On October 23, 2020, Parent acquired PCI Strategic Management, LLC (“PCI” or “Predecessor”). On December 21, 2020, NuWave acquired 100% of the equity of PCI in a series of transactions which resulted in BigBear.ai Holdings being a wholly owned subsidiary of Parent. These transactions left Lake Parent with no assets or operations, and it was dissolved. BigBear.ai Holdings includes the Predecessor, which is comprised of PCI prior to its acquisition date, and the Successor, including NuWave, PCI, Open Solutions and ProModel after the acquisition of each, respectively.

Immediately prior to the stockholder vote for the Merger, GigCapital4 executed a series of Forward Share Purchase Agreements (“FPAs”) with certain investors. Included within the FPAs is a provision that each of the participants would not redeem their shares and instead would hold the shares for a period of up to three months following the consummation of the Merger, at which time they will have the right to sell the shares to the Company for $10.15 per share.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note B—Summary of Significant Accounting Policies Basis of Presentation We prepared these consolidated financial statements in accordance with U.S. generally accepted accounting principles ( “GAAP” 10-Q “SEC” S-X. In the opinion of management, these consolidated financial statements reflect all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations, financial condition, and cash flows for the interim periods presented. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates. Significant estimates inherent in the preparation of our consolidated financial statements include, but are not limited to, accounting for revenue and cost recognition; evaluation of goodwill; intangible assets; and other assets for impairment; income taxes; equity-based compensation; fair value measurements; and contingencies. We eliminate intercompany balances and transactions in consolidation. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the full year or future periods. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act” non-emerging This may make comparison of the Company’s financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Recently Adopted Accounting Pronouncements In October 2021, the FASB issued ASU No. 2021-08, Business Combinations ASC 805 Accounting for Contract Assets and Contract Liabilities from Contracts with Customers ASU 2021-08 ASU No. 2014-09, Revenue from Contracts with Customers ASC 606 2021-08 2021-08 2021-08	Note B—Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and all intercompany balances and transactions have been eliminated in consolidation. Amounts presented within the consolidated financial statements and accompanying notes are presented in thousands of U.S. dollars unless stated otherwise, except for percentages, units, shares, per unit, and per share amounts. The period from May 22, 2020 (inception) through December 31, 2020 and as of December 31, 2020 (the “Successor 2020 Period”) and the year ended December 31, 2021 (the “Successor 2021 Period”) relate to activity of BigBear.ai Holdings and its subsidiaries. The year ended December 31, 2019 (the “Predecessor 2019 Period”), and the period from January 1, 2020 to October 22, 2020 (the “Predecessor 2020 Period”) relate to the predecessor period. The Successor 2020 Period begins before the Predecessor 2020 Period ended due to the acquisitions that took place prior to the acquisition of PCI. The PCI, NuWave, Open Solutions, and ProModel acquisitions were accounted for as business combinations in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”), and the resulting new basis of accounting is reflected in the Successor 2020 Period as of each acquisition date. As a result, financial information of the Predecessor and Successor periods has been prepared under two different bases of accounting and therefore are not comparable. PCI was identified as the Predecessor through an analysis of various factors, including the size, financial characteristics, and ongoing management. The audited consolidated financial statements are presented as described below: • The consolidated financial statements for the Predecessor 2019 Period, which includes a full year of operating results of PCI. • The consolidated financial statements for the Predecessor 2020 Period, which includes the operating results of PCI from January 1, 2020 to October 22, 2020. • The combined financial statements for the Successor 2020 Period, which includes the operating results of BigBear.ai Holdings and its subsidiaries from each of their respective acquisition dates through December 31, 2020. • The consolidated financial statements for the Successor 2021 Period, which includes the operating results of BigBear.ai Holdings and its subsidiaries for the year ended December 31, 2021. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, actual results could differ materially from those estimates. Accounting policies subject to estimates include valuation of goodwill, intangible assets, impairments, revenue recognition, income taxes, business combinations and equity-based compensation. Business Combinations The Company utilizes the acquisition method of accounting under ASC 805, for all transactions and events in which it obtains control over one or more other businesses (even if less than 100% ownership is acquired), to recognize the fair value of all assets and liabilities assumed and to establish the acquisition date fair value as of the measurement date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed as of the acquisition date, the estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. For changes in the valuation of intangible assets between the preliminary and final purchase price allocation, the related amortization is adjusted in the period it occurs. Subsequent to the measurement period, any adjustment to assets acquired or liabilities assumed is included in operating results in the period in which the adjustment is determined. Transaction expenses that are incurred in connection with a business combination, other than costs associated with the issuance of debt or equity securities, are expensed as incurred. Revenue Recognition The Company’s revenues from contracts with customers are from offerings including artificial intelligence and machine learning, data science, advanced analytics, offensive and defensive cyber, data management, cloud solutions, digital engineering, and systems integration, primarily with the U.S. Government and its agencies. The Company also serves various commercial customers. The Company organizes its solutions into three categories: 1. Observe–helps customers collect, normalize and curate data from a variety of sources in real-time. 2. Orient–uses low code, composable, distributed, and event-driven predictive analytics to uncover hidden items in raw data and make sense of incomplete data. 3. Dominate–helps customers turn data into insights by recommending and evaluating multiple courses of action through data visualization and descriptive analytics. Each of the Company’s solutions can be sold individually or combined and sold together. Regardless of whether a customer is procuring only one of the Company’s solutions or a combination of solutions, the Company’s contracts generally include a significant service of integrating the solutions with the Company’s customer’s existing solutions and information systems. After the Company implements the solutions, the Company may also enter into contracts with the customers to further refine or customize these solutions to either enhance the functionality or adjust for changes in the customer’s requirements. These post-implementation service contracts are generally performed on a time-and-materials The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company performs under various types of contracts, which generally include firm-fixed-price (“FFP”) and time-and-materials Under fixed-price contracts, the Company agrees to perform the specified work for a pre-determined pre-determined The Company assesses each contract at its inception to determine whether it should be combined with other contracts. When making this determination, the Company considers factors such as whether two or more contracts were negotiated and executed at or near the same time or were negotiated with an overall profit objective. If combined, the Company treats the combined contracts as one single contract for revenue recognition purposes. The Company generally uses internally developed and third-party applications, which the Company integrates, when implementing solutions to meet specific customer requirements. The Company evaluates the solutions or services promised in each contract at inception to determine whether the contract should be accounted for as having one or more performance obligations. Each of the Company’s solutions is capable of being distinct as the customer can benefit from each individual solution on its own or with other resources that are readily available. When customer contracts include a significant service of integrating the solutions to provide a set of integrated or highly interrelated tasks, the Company accounts for these arrangements as a single performance obligation. While the contracts provide customers access to the Company’s solutions, the contracts generally do not contain separate licensing provisions for independent use of the underlying internally developed software. Additionally, these components are highly interdependent and highly interrelated into the solutions delivered to the Company’s customers. Therefore, these components are not capable of being distinct and are not separately identifiable from the other promises in the contract. In cases where customer contracts have an explicit licensing provision to the underlying software, such software is generally accounted for as a separate performance obligation. The Company determines the transaction price for each contract based on the consideration the Company expects to receive for the solutions or services being provided under the contract. For contracts where a portion of the price may vary, the Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company analyzes the risk of a significant revenue reversal and if necessary, constrains the amount of variable consideration recognized in order to mitigate this risk. At the inception of a contract, the Company estimates the transaction price based on its current rights and does not contemplate future modifications (including unexercised options) or follow-on For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the estimated standalone selling price of the solution or service underlying each performance obligation. The standalone selling price represents the amount for which the Company would sell the solution or service to a customer on a standalone basis (i.e., not bundled with any other solutions or services). The Company’s contracts with the U.S. government are subject to the Federal Acquisition Regulation (“FAR”) and priced on estimated or actual costs of providing the goods or services. The FAR provides guidance on types of costs that are allowable in establishing prices for goods and services provided to the U.S. government and its agencies. Each contract is competitively priced and bid separately. Pricing for non-U.S. The Company recognizes revenue as performance obligations are satisfied and the customer obtains control of the solutions and services. In determining when performance obligations are satisfied, the Company considers factors such as contract terms, payment terms and whether there is an alternative future use of the solution or service. Substantially all of the Company’s revenue is recognized over time as the Company performs under the contract because control of the work in process transfers continuously to the customer. For most contracts with the U.S. Government, this continuous transfer of control of the work in process to the customer is supported by clauses in the contract that give the customer ownership of work in process and allow the customer to unilaterally terminate the contract for convenience and pay the Company for costs incurred plus a reasonable profit. For most non-U.S. non-performance, For performance obligations to deliver solutions with continuous transfer of control to the customer, revenue is recognized based on the extent of progress towards completion of the performance obligation, generally using the percentage-of-completion cost-to-cost because it best depicts the transfer of control to the customer as the Company incurs costs on the contracts. Under the percentage-of-completion cost-to-cost For arrangements with the U.S. Government, the Company generally does not begin work on contracts until funding is appropriated by the customer. Billing timetables and payment terms on the Company’s contracts vary based on a number of factors, including the contract type. CPFF and T&M contracts are generally billed on a monthly basis. FFP contracts are generally billed based on milestones, which are the achievement of specific events as defined in the contract. Amounts billed and due from customers are classified as receivables on the combined balance sheets. On some contracts, the Company may be entitled to receive an advance payment, which is not considered a significant financing component because it is used to facilitate inventory demands at the onset of a contract and to safeguard the Company from the failure of the other party to abide by some or all of their obligations under the contract. In some cases where a portion of payment retained by the customer is not considered a significant financing component; the Company expects, at contract inception, that the lag period between the transfer of a promised good or service to a customer and when the customer pays for that good or service will not constitute a significant financing component. Sale of Products Revenue from sale of products to customers purchased from third parties is recognized at a point in time when control has transferred to the customer. Control is transferred to the customer upon customer acceptance or receipt of the product. At this point in time, the Company has a present right to payment, and the customer has legal title and physical possession of the product as well as the risks and rewards of ownership. Contract Balances Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract liabilities consist of billings in excess of revenues and customer advances. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues. Cash and Cash Equivalents Cash and cash equivalents are comprised of cash on hand, cash balances with banks and similar institutions and all highly liquid investments with an original maturity of three months or less when purchased. Restricted Cash The Company’s restricted cash consists of cash deposited into escrow accounts reflecting the full obligation to certain investors related to the FPAs. The funds held in the escrow accounts will not be available to the Company for three months following the consummation of the Merger unless and until any of the Investors sell these shares in the market or the investors redeem their shares under FPAs by March 7, 2022. Notwithstanding the sale of shares by any FPA investors, the restricted cash will be used to settle any of the Company’s repurchase obligations arising as a result of a FPA investor requiring the Company to repurchase its shares. The Company settled its obligations under the FPAs subsequent to December 31, 2021. See “Note V — Subsequent Events” for additional information.​​​​​​​ Property and Equipment Property and equipment are the long-lived, physical assets of the Company acquired for use in the Company’s normal business operations and not intended for resale by the Company. These assets are recorded at cost. Renewals and betterments that increase the useful lives of the assets are capitalized. Repair and maintenance expenditures that increase the efficiency of the assets are expensed as incurred. Assets under capital leases are recorded at the present value of the minimum lease payments required during the lease period. Depreciation is based on the estimated useful lives of the assets using the straight-line method and is included in selling, general and administrative or cost of revenues based upon the asset. Expected useful lives are reviewed at least annually. Estimated useful lives are as follows: Property and equipment Estimate useful Computer equipment 3 Furniture and fixtures 7 Laboratory equipment 5-10 Software 3-5 Leasehold improvements 5 or lease term As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations. The Company regularly evaluates its property and equipment for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable, in accordance with ASC 360, Property, Plant, and Equipment Finite-lived Intangible Assets Finite-lived intangible assets result from the Company’s various business combinations and consist of identifiable finite-lived intangible assets, including technology and customer relationships. These finite-lived intangible assets are reported at cost, net of accumulated amortization, and are either amortized on a straight-line basis over their estimated useful lives or over the period the economic benefits of the intangible asset are consumed. The Company regularly evaluates its intangible assets other than goodwill for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable, in accordance with ASC 350, Intangibles–Goodwill and Other Leases In accordance with ASC 840, Leases ASC 840 non-contingent Warrants As part of GigCapital4’s Initial Public Offering, public and private warrants were issued, which were assumed by BigBear.ai upon consummation of the Merger. Warrants are accounted for in accordance with the guidance of ASC 815, Derivatives and Hedging ASC 815 Written Put Option The Written Put Option is a liability under ASC 480, Distinguishing Liabilities from Equity Fair Value of Financial Instruments The Company measures certain financial assets and liabilities at fair value. ASC 820, Fair Value Measurement and Disclosures (“ASC 820”) Level 1—Quoted prices for identical instruments in active markets; Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. These inputs are based on Company’s own assumptions about current market conditions and require significant management judgement or estimation. Financial instruments consist of cash equivalents, accounts receivable, accounts payable, accrued liabilities, private warrants, written put options, and debt. Cash equivalents are stated at fair value on a recurring basis. Accounts receivable, accounts payable and accrued liabilities are stated at their carrying value, which approximates fair value due to the short time to the expected receipt of payment date. Private warrants and written put options are marked to fair value on a periodic basis. Income Taxes The Company estimates its current tax expense together with assessing temporary differences resulting from differing treatment of items not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities on the Company’s consolidated balance sheets, which are estimated based upon the difference between the financial statement and tax bases of assets and liabilities using the enacted tax rates that will be in effect when these differences reverse. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the Company’s consolidated statements of operations become deductible expenses under applicable income tax laws or loss or credit carry forwards are utilized. Accordingly, the realization of the Company’s deferred tax assets are dependent on future taxable income against which these deductions, losses, and credits can be utilized. The Company evaluates the realizability of its deferred tax assets and recognizes a valuation allowance when it is more likely than not that a future benefit on such deferred tax assets will not be realized. Changes in the valuation allowance, when recorded, would be included in the Company’s consolidated statements of operations. Management’s judgment is required in determining the Company’s valuation allowance recorded against its net deferred tax assets. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to uncertain tax positions in its provision (benefit) for income taxes. As of December 31, 2021, there were no accruals for uncertain tax positions. Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, certificates of deposit, and accounts receivable. The Company places its cash and cash equivalents with financial institutions of high credit quality. At times, such amounts may exceed federally insured limits. Cash and cash equivalents and restricted cash on deposit or invested with financial and lending institutions was $169,921 and $9,704, as of December 31, 2021 and December 31, 2020, respectively. The Company provides credit to customers in the normal course of business. The carrying amount of current accounts receivable is stated at cost, net of an allowance for doubtful accounts. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that will not be fully collected. The allowance is based on the assessment of the following factors: customer creditworthiness, historical payment experience, and age of outstanding accounts receivable and any applicable collateral. Segment Information Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it operates in two operating and reportable segments, Cyber & Engineering and Analytics, as the CODM reviews financial information presented for both segments on a disaggregated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Cyber & Engineering The Cyber & Engineering segment provides high-end Analytics The Analytics segment provides high-end The Predecessor operated as a single reportable operating segment of Cyber & Engineering. Goodwill Goodwill is the amount by which the purchase price exceeded the fair value of the net identifiable assets acquired and liabilities assumed in a business combination on the date of acquisition. Goodwill is assessed for impairment at least annually as of October 1, on a reporting unit basis, or when events and circumstances occur indicating that the recorded goodwill may be impaired. The Company assesses impairment first on a qualitative basis to determine if a quantitative assessment is necessary. In circumstances where the qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit does not exceed its carrying value, the Company performs a quantitative impairment test by which the goodwill impairment loss is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. All indefinite-lived assets are reviewed for impairment annually, and as necessary if indicators of impairment are present. Internal-Use Costs incurred in developing internal-use Equity-based Compensation Pursuant to ASC 718, Compensation – Stock Compensation equity classified equity-based awards with performance conditions, the Company recognizes equity-based compensation cost using the accelerated attribution method over the requisite service period when the Company determines it is probable that the performance condition will be satisfied. The Company recognizes forfeitures of equity-based awards in the period they occur. Research and Development Costs Research and development costs are primarily made up of labor charges, prototype material, and development expenses. Research and development costs are expensed in the period incurred. Advertising Costs All advertising, promotional and marketing costs are expensed when incurred and are included in selling, general and administrative expenses within the consolidated statements of operations. The table below presents advertising costs for the following periods: Successor Predecessor Year Ended December 31, Period from May 22, 2020 December 31, 2020 Period from Year Ended December 31, 2019 Advertising Costs $ 763 $ 35 $ 57 $ 42 Net Income (Loss) per Share Basic net loss per share is computed by dividing net loss applicable to stockholders by the weighted average number of shares outstanding for the period. Diluted net loss per share assumes conversion of potentially dilutive shares, such as stock options. The Company’s consolidated statements of operations include a presentation of net income (loss) per share for the Successor 2021 Period and Successor 2020 Period.

The effective tax rate for the three months ended March 31, 2022 differs from the U.S. federal income tax rate of 21.0% primarily due to state and local corporate income taxes as well as the valuation allowance that was established during 2021. The effective tax rate for the three months ended March 31, 2021 differs from the U.S. federal income tax rate of 21.0% primarily due to non-deductible	Note K—Income Taxes The Predecessor was established and taxed as a partnership, and therefore, was not generally subject to federal, state and local corporate income taxes. The tax attributes of the Predecessor are reported on each members’ respective income tax return. Consequently, the provision for income tax provided in the accompanying financial statements arose in states that assess income tax at the entity level. The Successor is established as a limited liability company and has elected to be taxed as a corporation for federal, state, and local income tax purposes. The components of income tax expense (benefit) were as follows: Successor Predecessor Year Ended December 31, 2021 Period from May 22, 2020 December 31, 2020 Period from Year Ended December 31, Federal: Deferred $ 797 $ (2,047) $ — $ — Total Federal 797 (2,047 ) — — State: Current 42 4 11 11 Deferred 245 (590 ) (8 ) (2 ) Total State 287 (586 ) 3 9 Income tax expense (benefit) $ 1,084 $ (2,633) $ 3 $ 9 The following is the reconciliation of the amounts computed using the federal statutory income tax rate and the amounts computed using the effective income tax rate: Successor Predecessor Year Ended December 31, Period from May 22, 2020 December 31, 2020 Period from Year Ended December 31, Tax benefit at federal statutory rates $ (25,718 ) $ (2,199 ) $ — $ — State income tax, net of federal tax benefit (2,163 ) (628 ) 3 9 Class B Incentive Unit equity-based compensation 12,673 — — — Valuation allowance 8,967 — — — Net increase in fair value of derivatives 7,004 — — — Transaction expenses — 119 — — Other permanent differences 321 75 — — Income tax expense (benefit) $ 1,084 $ (2,633 ) $ 3 $ 9 The table below presents the components of net deferred tax assets and deferred liabilities: Successor December 31, December 31, Deferred tax assets: Net operating loss carryforwards $ 9,932 $ 891 Interest carryforwards 2,151 161 Amortizable transaction costs 1,410 — Accrued expenses 1,361 86 Deferred rent 51 20 Equity-based compensation 50 — Other assets 114 20 Total deferred tax assets 15,069 1,178 Valuation allowance (13,439 ) — Net deferred tax assets 1,630 1,178 Deferred tax liabilities: Depreciation and amortization 1,267 204 Prepaid expenses 611 137 Deferred revenue — 43 Total deferred tax liabilities 1,878 384 Net deferred tax (liabilities) assets $ (248 ) $ 794 As of December 31, 2021, the Company has $34,678 of U.S. federal net operating losses, all of which can be carried forward indefinitely. As of December 31, 2021, the Company has $45,998 of U.S. state net operating losses which will begin to expire in 2031. A valuation allowance is provided for deferred income tax assets when it is more likely than not that future tax benefits will not be realized. The Company assesses whether a valuation allowance should be established against deferred tax assets based upon consideration of all available evidence, both positive and negative, using a more likely than not standard. This assessment considers, among other matters, the Company’s history of losses, the duration of statutory carryforward periods, the Company’s experience with tax attributes expiring, impacts of enacted changes in tax laws and tax planning strategies, and the taxable income generated through the future reversals of deferred tax liabilities. In making such judgments, significant weight is given to evidence that can be objectively verified. After analyzing all available evidence, the Company determined it was more likely that it would be not able to utilize all of its deferred tax assets, and has therefore established a full valuation allowance. The net change in the valuation allowance was $13,439 during 2021.

The number of units granted or to be granted by the Parent are determined by dividing the compensation payable for the quarter by the fair value of the Class A units at the end of each respective quarter. The total value of the Class A units granted to such Board of Directors for the three months ended March 31, 2022 and three months ended March 31, 2021 was $ — Class B Unit Incentive Plan In February 2021, the Company’s Parent adopted a compensatory benefit plan (the “Class B Unit Incentive Plan” service providers of the Company’s Parent or its Subsidiaries in the form of the Parent’s Class B Units “Incentive Units” “Tranche I,” “Tranche II,” and “Tranche III” The assumptions used in determining the fair val February 16, 2021 Volatility 57.0 % Risk-free interest rate 0.1 % Expected time to exit (in years) 1.6 On July 29, 2021, the Company’s Parent amended the Class B Unit Incentive Plan so that the Tranche I and the Tranche III Incentive Units will immediately become fully vested, subject to continued employment or provision of services, upon the closing of the transaction stipulated in the Agreement and Plan of Merger (the “Merger Agreement” Equity-based compensation for awards with performance conditions is based on the probable outcome of the related performance condition. The performance conditions required to vest per the amended Incentive Plan remain improbable until they occur due to the unpredictability of the events required to meet the vesting conditions. As such events are not considered probable until they occur, recognition of equity-based compensation for the Incentive Units is deferred until the vesting conditions are met. Once the event occurs, unrecognized compensation cost associated with the performance-vesting Incentive Units (based on their modification date fair value) will be recognized based on the portion of the requisite service period that has been rendered. The modification date fair value of the Incentive Units was $9.06 per unit. The assumptions used in determining the fair value of the Incentive Units at the modification date are as follows: July 29, 2021 Volatility 46.0 % Risk-free interest rate 0.2 % Expected time to exit (in years) 1.2 The volatility used in the determination of the fair value of the Incentive Units was based on analysis of the historical volatility of guideline public companies and factors specific to the Company. On December 7, 2021, the previously announced merger was consummated. As a result, the Tranche I and Tranche III Incentive Units immediately became fully vested and the performance condition for the Tranche II Incentive Units was met. The fair value determined at the date of the amendment of the Class B Unit Incentive Plan was immediately recognized as compensation expense on the vesting date for Tranches I and III. Compensation expense for the Tranche II Incentive Units is recognized over the derived service period of 30 months from the modification date, which resulted in approximately 17.0% of the compensation expense for Tranche II being recognized during the year ended December 31, 2021. The remaining compensation expense for the Tranche II Incentive Units will be recognized over the remaining service period of approximately 25 months. During the three months ended March 31, 2022, the Company’s Parent modified the vesting conditions for one former employee. Under the original terms of the grant agreements, Incentive Units are forfeited upon separation. Due to the amended agreement, the Incentive Units held by the former employee will continue to vest through the vesting date. The result of the amended agreement is an accounting modification that resulted in 100% of the compensation expense being recognized for the former employee based on the modification date fair value. The incremental compensation cost recognized as a result of the modification was $219 during the three months ended March 31, 2022. The total compensation expense recognized by the Company for Tranche II Incentive Units, including the effects of the modification, was $2,706 during the three months ended March 31, 2022, of which $2,353 was recognized in selling, general and administrative expense and $353 in cost of revenues.

The table below presents the activity in the RSUs: Unvested and outstanding as of January 1, 2021 — Granted 403,300 Vested — Forfeited — Unvested and outstanding as of December 31, 2021 403,300 The Company recognizes equity-based compensation expense for RSUs on a straight-line over the requisite service period. During the year ended December 31, 2021, the Company recognized $134 and $3 of equity-based compensation expense in selling, general and administrative expense and cost of revenues, respectively. As of December 31, 2021, there was approximately $3,908 of unrecognized compensation costs related to the RSUs. Performance Stock Units On December 7, 2021, pursuant to the Plan, the Company’s Board of Directors communicated the key terms and committed to grant Performance Stock Units (“PSUs”) to an employee. The grant date of this award is December 7, 2021. The percentage of vesting is based on achieving certain performance criteria during each of the 4 fiscal years ended December 31, 2022 through December 31, 2025, provided that the employee remains in continuous service on each vesting date. Vesting will not occur unless a minimum performance criteria threshold is achieved. There is a maximum of 37,500 PSUs available to vest during each of the four The table below presents the activity in the PSUs: Unvested and outstanding as of January 1, 2021 — Granted 150,000 Vested — Forfeited — Unvested and outstanding as of December 31, 2021 150,000 The Company recognized no equity-based compensation expense for the PSUs during the year ended December 31, 2021 as it was not considered probable that the performance conditions would be achieved.

Because of the net loss incurred during the three months ended March 31, 2022, the impacts of dilutive instruments would have been anti-dilutive for the period presented and have been excluded from loss per share calculations. There were no potentially dilutive instruments for the three months ended March 31, 2021. On April 7, 2022, the Company issued 649,976 shares of common stock as part of the transaction to acquire ProModel Corporation. Refer to Note R—Subsequent Events for more information on this acquisition.	Note R—Net Income (Loss) Per Share Prior to the Merger, the membership structure of BigBear.ai Holdings included units which had profit interests. As result of the Merger, which was accounted for as a reverse recapitalization, the Company has retroactively adjusted the weighted averages shares outstanding prior to the Merger to give effect to the exchange ratio used to determine the number of shares of common stock into which they were converted, which is reflected in the denominator of basic and diluted net loss per share for the Successor 2020 Period below.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended	12 Months Ended
	Mar. 31, 2022	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation We prepared these consolidated financial statements in accordance with U.S. generally accepted accounting principles ( “GAAP” 10-Q “SEC” S-X. In the opinion of management, these consolidated financial statements reflect all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations, financial condition, and cash flows for the interim periods presented. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates. Significant estimates inherent in the preparation of our consolidated financial statements include, but are not limited to, accounting for revenue and cost recognition; evaluation of goodwill; intangible assets; and other assets for impairment; income taxes; equity-based compensation; fair value measurements; and contingencies. We eliminate intercompany balances and transactions in consolidation. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the full year or future periods. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K	Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and all intercompany balances and transactions have been eliminated in consolidation. Amounts presented within the consolidated financial statements and accompanying notes are presented in thousands of U.S. dollars unless stated otherwise, except for percentages, units, shares, per unit, and per share amounts. The period from May 22, 2020 (inception) through December 31, 2020 and as of December 31, 2020 (the “Successor 2020 Period”) and the year ended December 31, 2021 (the “Successor 2021 Period”) relate to activity of BigBear.ai Holdings and its subsidiaries. The year ended December 31, 2019 (the “Predecessor 2019 Period”), and the period from January 1, 2020 to October 22, 2020 (the “Predecessor 2020 Period”) relate to the predecessor period. The Successor 2020 Period begins before the Predecessor 2020 Period ended due to the acquisitions that took place prior to the acquisition of PCI. The PCI, NuWave, Open Solutions, and ProModel acquisitions were accounted for as business combinations in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”), and the resulting new basis of accounting is reflected in the Successor 2020 Period as of each acquisition date. As a result, financial information of the Predecessor and Successor periods has been prepared under two different bases of accounting and therefore are not comparable. PCI was identified as the Predecessor through an analysis of various factors, including the size, financial characteristics, and ongoing management. The audited consolidated financial statements are presented as described below: • The consolidated financial statements for the Predecessor 2019 Period, which includes a full year of operating results of PCI. • The consolidated financial statements for the Predecessor 2020 Period, which includes the operating results of PCI from January 1, 2020 to October 22, 2020. • The combined financial statements for the Successor 2020 Period, which includes the operating results of BigBear.ai Holdings and its subsidiaries from each of their respective acquisition dates through December 31, 2020. • The consolidated financial statements for the Successor 2021 Period, which includes the operating results of BigBear.ai Holdings and its subsidiaries for the year ended December 31, 2021.
Use of Estimates		Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, actual results could differ materially from those estimates. Accounting policies subject to estimates include valuation of goodwill, intangible assets, impairments, revenue recognition, income taxes, business combinations and equity-based compensation.
Emerging Growth Company	Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act” non-emerging This may make comparison of the Company’s financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Business Combinations		Business Combinations The Company utilizes the acquisition method of accounting under ASC 805, for all transactions and events in which it obtains control over one or more other businesses (even if less than 100% ownership is acquired), to recognize the fair value of all assets and liabilities assumed and to establish the acquisition date fair value as of the measurement date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed as of the acquisition date, the estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. For changes in the valuation of intangible assets between the preliminary and final purchase price allocation, the related amortization is adjusted in the period it occurs. Subsequent to the measurement period, any adjustment to assets acquired or liabilities assumed is included in operating results in the period in which the adjustment is determined. Transaction expenses that are incurred in connection with a business combination, other than costs associated with the issuance of debt or equity securities, are expensed as incurred.
Revenue Recognition		Revenue Recognition The Company’s revenues from contracts with customers are from offerings including artificial intelligence and machine learning, data science, advanced analytics, offensive and defensive cyber, data management, cloud solutions, digital engineering, and systems integration, primarily with the U.S. Government and its agencies. The Company also serves various commercial customers. The Company organizes its solutions into three categories: 1. Observe–helps customers collect, normalize and curate data from a variety of sources in real-time. 2. Orient–uses low code, composable, distributed, and event-driven predictive analytics to uncover hidden items in raw data and make sense of incomplete data. 3. Dominate–helps customers turn data into insights by recommending and evaluating multiple courses of action through data visualization and descriptive analytics. Each of the Company’s solutions can be sold individually or combined and sold together. Regardless of whether a customer is procuring only one of the Company’s solutions or a combination of solutions, the Company’s contracts generally include a significant service of integrating the solutions with the Company’s customer’s existing solutions and information systems. After the Company implements the solutions, the Company may also enter into contracts with the customers to further refine or customize these solutions to either enhance the functionality or adjust for changes in the customer’s requirements. These post-implementation service contracts are generally performed on a time-and-materials The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company performs under various types of contracts, which generally include firm-fixed-price (“FFP”) and time-and-materials Under fixed-price contracts, the Company agrees to perform the specified work for a pre-determined pre-determined The Company assesses each contract at its inception to determine whether it should be combined with other contracts. When making this determination, the Company considers factors such as whether two or more contracts were negotiated and executed at or near the same time or were negotiated with an overall profit objective. If combined, the Company treats the combined contracts as one single contract for revenue recognition purposes. The Company generally uses internally developed and third-party applications, which the Company integrates, when implementing solutions to meet specific customer requirements. The Company evaluates the solutions or services promised in each contract at inception to determine whether the contract should be accounted for as having one or more performance obligations. Each of the Company’s solutions is capable of being distinct as the customer can benefit from each individual solution on its own or with other resources that are readily available. When customer contracts include a significant service of integrating the solutions to provide a set of integrated or highly interrelated tasks, the Company accounts for these arrangements as a single performance obligation. While the contracts provide customers access to the Company’s solutions, the contracts generally do not contain separate licensing provisions for independent use of the underlying internally developed software. Additionally, these components are highly interdependent and highly interrelated into the solutions delivered to the Company’s customers. Therefore, these components are not capable of being distinct and are not separately identifiable from the other promises in the contract. In cases where customer contracts have an explicit licensing provision to the underlying software, such software is generally accounted for as a separate performance obligation. The Company determines the transaction price for each contract based on the consideration the Company expects to receive for the solutions or services being provided under the contract. For contracts where a portion of the price may vary, the Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company analyzes the risk of a significant revenue reversal and if necessary, constrains the amount of variable consideration recognized in order to mitigate this risk. At the inception of a contract, the Company estimates the transaction price based on its current rights and does not contemplate future modifications (including unexercised options) or follow-on For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the estimated standalone selling price of the solution or service underlying each performance obligation. The standalone selling price represents the amount for which the Company would sell the solution or service to a customer on a standalone basis (i.e., not bundled with any other solutions or services). The Company’s contracts with the U.S. government are subject to the Federal Acquisition Regulation (“FAR”) and priced on estimated or actual costs of providing the goods or services. The FAR provides guidance on types of costs that are allowable in establishing prices for goods and services provided to the U.S. government and its agencies. Each contract is competitively priced and bid separately. Pricing for non-U.S. The Company recognizes revenue as performance obligations are satisfied and the customer obtains control of the solutions and services. In determining when performance obligations are satisfied, the Company considers factors such as contract terms, payment terms and whether there is an alternative future use of the solution or service. Substantially all of the Company’s revenue is recognized over time as the Company performs under the contract because control of the work in process transfers continuously to the customer. For most contracts with the U.S. Government, this continuous transfer of control of the work in process to the customer is supported by clauses in the contract that give the customer ownership of work in process and allow the customer to unilaterally terminate the contract for convenience and pay the Company for costs incurred plus a reasonable profit. For most non-U.S. non-performance, For performance obligations to deliver solutions with continuous transfer of control to the customer, revenue is recognized based on the extent of progress towards completion of the performance obligation, generally using the percentage-of-completion cost-to-cost because it best depicts the transfer of control to the customer as the Company incurs costs on the contracts. Under the percentage-of-completion cost-to-cost For arrangements with the U.S. Government, the Company generally does not begin work on contracts until funding is appropriated by the customer. Billing timetables and payment terms on the Company’s contracts vary based on a number of factors, including the contract type. CPFF and T&M contracts are generally billed on a monthly basis. FFP contracts are generally billed based on milestones, which are the achievement of specific events as defined in the contract. Amounts billed and due from customers are classified as receivables on the combined balance sheets. On some contracts, the Company may be entitled to receive an advance payment, which is not considered a significant financing component because it is used to facilitate inventory demands at the onset of a contract and to safeguard the Company from the failure of the other party to abide by some or all of their obligations under the contract. In some cases where a portion of payment retained by the customer is not considered a significant financing component; the Company expects, at contract inception, that the lag period between the transfer of a promised good or service to a customer and when the customer pays for that good or service will not constitute a significant financing component.
Sale of Products		Sale of Products Revenue from sale of products to customers purchased from third parties is recognized at a point in time when control has transferred to the customer. Control is transferred to the customer upon customer acceptance or receipt of the product. At this point in time, the Company has a present right to payment, and the customer has legal title and physical possession of the product as well as the risks and rewards of ownership.
Contract Balances		Contract Balances Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract liabilities consist of billings in excess of revenues and customer advances. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues.
Cash and Cash Equivalents		Cash and Cash Equivalents Cash and cash equivalents are comprised of cash on hand, cash balances with banks and similar institutions and all highly liquid investments with an original maturity of three months or less when purchased.
Restricted Cash		Restricted Cash The Company’s restricted cash consists of cash deposited into escrow accounts reflecting the full obligation to certain investors related to the FPAs. The funds held in the escrow accounts will not be available to the Company for three months following the consummation of the Merger unless and until any of the Investors sell these shares in the market or the investors redeem their shares under FPAs by March 7, 2022. Notwithstanding the sale of shares by any FPA investors, the restricted cash will be used to settle any of the Company’s repurchase obligations arising as a result of a FPA investor requiring the Company to repurchase its shares. The Company settled its obligations under the FPAs subsequent to December 31, 2021. See “Note V — Subsequent Events” for additional information.​​​​​​​
Property and Equipment		Property and Equipment Property and equipment are the long-lived, physical assets of the Company acquired for use in the Company’s normal business operations and not intended for resale by the Company. These assets are recorded at cost. Renewals and betterments that increase the useful lives of the assets are capitalized. Repair and maintenance expenditures that increase the efficiency of the assets are expensed as incurred. Assets under capital leases are recorded at the present value of the minimum lease payments required during the lease period. Depreciation is based on the estimated useful lives of the assets using the straight-line method and is included in selling, general and administrative or cost of revenues based upon the asset. Expected useful lives are reviewed at least annually. Estimated useful lives are as follows: Property and equipment Estimate useful Computer equipment 3 Furniture and fixtures 7 Laboratory equipment 5-10 Software 3-5 Leasehold improvements 5 or lease term As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations. The Company regularly evaluates its property and equipment for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable, in accordance with ASC 360, Property, Plant, and Equipment
Finite-lived Intangible Assets		Finite-lived Intangible Assets Finite-lived intangible assets result from the Company’s various business combinations and consist of identifiable finite-lived intangible assets, including technology and customer relationships. These finite-lived intangible assets are reported at cost, net of accumulated amortization, and are either amortized on a straight-line basis over their estimated useful lives or over the period the economic benefits of the intangible asset are consumed. The Company regularly evaluates its intangible assets other than goodwill for impairment when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable, in accordance with ASC 350, Intangibles–Goodwill and Other
Leases		Leases In accordance with ASC 840, Leases ASC 840 non-contingent
Warrants and Written Put Option		Warrants As part of GigCapital4’s Initial Public Offering, public and private warrants were issued, which were assumed by BigBear.ai upon consummation of the Merger. Warrants are accounted for in accordance with the guidance of ASC 815, Derivatives and Hedging ASC 815 Written Put Option The Written Put Option is a liability under ASC 480, Distinguishing Liabilities from Equity
Fair Value of Financial Instruments		Fair Value of Financial Instruments The Company measures certain financial assets and liabilities at fair value. ASC 820, Fair Value Measurement and Disclosures (“ASC 820”) Level 1—Quoted prices for identical instruments in active markets; Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. These inputs are based on Company’s own assumptions about current market conditions and require significant management judgement or estimation. Financial instruments consist of cash equivalents, accounts receivable, accounts payable, accrued liabilities, private warrants, written put options, and debt. Cash equivalents are stated at fair value on a recurring basis. Accounts receivable, accounts payable and accrued liabilities are stated at their carrying value, which approximates fair value due to the short time to the expected receipt of payment date. Private warrants and written put options are marked to fair value on a periodic basis.
Income Taxes		Income Taxes The Company estimates its current tax expense together with assessing temporary differences resulting from differing treatment of items not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities on the Company’s consolidated balance sheets, which are estimated based upon the difference between the financial statement and tax bases of assets and liabilities using the enacted tax rates that will be in effect when these differences reverse. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the Company’s consolidated statements of operations become deductible expenses under applicable income tax laws or loss or credit carry forwards are utilized. Accordingly, the realization of the Company’s deferred tax assets are dependent on future taxable income against which these deductions, losses, and credits can be utilized. The Company evaluates the realizability of its deferred tax assets and recognizes a valuation allowance when it is more likely than not that a future benefit on such deferred tax assets will not be realized. Changes in the valuation allowance, when recorded, would be included in the Company’s consolidated statements of operations. Management’s judgment is required in determining the Company’s valuation allowance recorded against its net deferred tax assets. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to uncertain tax positions in its provision (benefit) for income taxes. As of December 31, 2021, there were no accruals for uncertain tax positions.
Concentration of Credit Risk		Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, certificates of deposit, and accounts receivable. The Company places its cash and cash equivalents with financial institutions of high credit quality. At times, such amounts may exceed federally insured limits. Cash and cash equivalents and restricted cash on deposit or invested with financial and lending institutions was $169,921 and $9,704, as of December 31, 2021 and December 31, 2020, respectively. The Company provides credit to customers in the normal course of business. The carrying amount of current accounts receivable is stated at cost, net of an allowance for doubtful accounts. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that will not be fully collected. The allowance is based on the assessment of the following factors: customer creditworthiness, historical payment experience, and age of outstanding accounts receivable and any applicable collateral.
Segment Information		Segment Information Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it operates in two operating and reportable segments, Cyber & Engineering and Analytics, as the CODM reviews financial information presented for both segments on a disaggregated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Cyber & Engineering The Cyber & Engineering segment provides high-end Analytics The Analytics segment provides high-end The Predecessor operated as a single reportable operating segment of Cyber & Engineering.
Goodwill		Goodwill Goodwill is the amount by which the purchase price exceeded the fair value of the net identifiable assets acquired and liabilities assumed in a business combination on the date of acquisition. Goodwill is assessed for impairment at least annually as of October 1, on a reporting unit basis, or when events and circumstances occur indicating that the recorded goodwill may be impaired. The Company assesses impairment first on a qualitative basis to determine if a quantitative assessment is necessary. In circumstances where the qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit does not exceed its carrying value, the Company performs a quantitative impairment test by which the goodwill impairment loss is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. All indefinite-lived assets are reviewed for impairment annually, and as necessary if indicators of impairment are present.
Internal-Use Software		Internal-Use Costs incurred in developing internal-use
Equity-based Compensation		Equity-based Compensation Pursuant to ASC 718, Compensation – Stock Compensation equity classified equity-based awards with performance conditions, the Company recognizes equity-based compensation cost using the accelerated attribution method over the requisite service period when the Company determines it is probable that the performance condition will be satisfied. The Company recognizes forfeitures of equity-based awards in the period they occur.
Research and Development Costs		Research and Development Costs Research and development costs are primarily made up of labor charges, prototype material, and development expenses. Research and development costs are expensed in the period incurred.
Advertising Costs		Advertising Costs All advertising, promotional and marketing costs are expensed when incurred and are included in selling, general and administrative expenses within the consolidated statements of operations. The table below presents advertising costs for the following periods: Successor Predecessor Year Ended December 31, Period from May 22, 2020 December 31, 2020 Period from Year Ended December 31, 2019 Advertising Costs $ 763 $ 35 $ 57 $ 42
Net Income (Loss) per Share/Unit		Net Income (Loss) per Share Basic net loss per share is computed by dividing net loss applicable to stockholders by the weighted average number of shares outstanding for the period. Diluted net loss per share assumes conversion of potentially dilutive shares, such as stock options. The Company’s consolidated statements of operations include a presentation of net income (loss) per share for the Successor 2021 Period and Successor 2020 Period.
