Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of the Business	Note A—Description of the Business Affiliates of AE Industrial Partners Fund II, LP (“AE”), a private equity firm specializing in aerospace, defense, space and government services, power generation, and specialty industrial markets, formed a series of acquisition vehicles on May 22, 2020, which included Lake Parent, LLC (“Lake Parent”), BigBear.ai Holdings, LLC, (“BigBear.ai Holdings” or “Successor”, formerly known as Lake Intermediate, LLC), BigBear.ai Intermediate Holdings, LLC (“BigBear.ai Intermediate”, formerly known as Lake Finance, LLC) and BigBear.ai, LLC, (“BigBear.ai”, formerly known as Lake Acquisition, LLC) with Lake Parent being the top holding company. BigBear.ai and BigBear.ai Intermediate are wholly owned subsidiaries of BigBear.ai Holdings. On June 19, 2020, BigBear.ai acquired NuWave Solutions, LLC (“NuWave”). Subsequently, NuWave entered into an agreement with Open Solutions Group, LLC (“Open Solutions”) to acquire 100% of its equity on December 2, 2020. On December 21, 2020, BigBear.ai acquired the Government Services division of ProModel Government Solutions Inc. (“ProModel”). Separately, AE also formed a series of acquisition vehicles on October 8, 2020 which included PCISM Ultimate Holdings, LLC (subsequently renamed to BBAI Ultimate Holdings, LLC, “Parent”), PCISM Holdings, LLC, PCISM Intermediate Holdings, LLC, and PCISM Intermediate II Holdings, LLC. 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. The Company offers a comprehensive suite of solutions including artificial intelligence (“AI”) and machine learning (“ML”), data science, advanced analytics, offensive and defensive cyber, data management, cloud solutions, digital engineering, and systems integration. On December 7, 2021, the previously announced merger (“Merger”) with GigCapital4, Inc. (“GigCapital4”) was consummated pursuant to the business combination agreement (the “Agreement”) dated June 4, 2021, as amended in July 2021 and December 2021, by and between GigCapital4 Merger Sub Corporation (the “Merger Sub”), a wholly owned subsidiary of GigCapital4, BigBear.ai Holdings, and Parent. 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. Upon the closing of the Merger, GigCapital4 was renamed to BigBear.ai, Holdings Inc. (“BigBear.ai” or the “Company”), the SEC registrant. As a result of the Merger, the Company received aggregate gross proceeds of $101,958 from GigCapital4’s trust account and PIPE Proceeds, and issued $200,000 of unsecured convertible notes that are convertible into 17,391,304 shares of the Company’s common stock at an initial Conversion Price of $11.50 (refer to Note I 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 the 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. AE became the majority stockholder of the Company, via its ownership of Parent, following the close of the Merger (83.5%).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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 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 minimum non-contingent rent 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 Software Costs incurred in developing internal-use Equity-based Compensation Pursuant to ASC 718, Compensation – Stock Compensation recognizes equity-based compensation cost on a straight-line basis over the vesting period of the award. For 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.

Income Taxes	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, 2021 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.​​​​​​​

Equity-Based Compensation

Equity-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Equity-Based Compensation	Note Q—Equity-Based Compensation Predecessor On June 11, 2019, the Predecessor granted 100 Class B Units to a Member in consideration for the Member’s services to the Predecessor, subject to terms and conditions stated in the profits interest grant agreement. The Class B Units granted upon full vesting represented 10% percent interest in the Predecessor. The Class B Units were non-voting profits The Class B Units granted had a service condition only, and equity-based compensation for the Class B Units was recognized on a straight-line basis over the requisite service period. The grant date fair value per unit of the Class B Units was $4,982 which was measured used the Black-Scholes Merton Option Pricing Model. The assumptions used in determining the fair value were as follows: As of June 11, Volatility 25.8 % Risk-free interest rate 1.89 % Expected time to exit (years) 2.5 The expected time to exit used in the determination of the fair value was based on the time to sale consistent with when investor return would be measured. The volatility used in the determination of the fair value was based on analysis of the selected asset volatility of guideline companies, re-leveled The table below presents the activity for the Class B Units: Balance as of January 1, 2019 — Granted during the year 100 Vested during the year (10 ) Forfeited during the year — Unvested as of December 31, 2019 90 Unvested as of October 22, 2020 90 Unvested Class B Units became fully vested and were settled for $731 of the purchase consideration on the PCI acquisition as of October 23, 2020. Selling, general and administrative expenses for the Predecessor 2020 Period and the Predecessor 2019 Period included $80 and $104 of equity-based compensation related to Class B Units, respectively. Successor Class A Units granted to board of directors Certain members of the board of directors of the Company have elected to receive their compensation for their services as a board member in stock, Class A units of the Parent. 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 year ended December 31, 2021 is $86, and is reflected in the selling, general and administrative expenses within the consolidated statements of operations. Class B Unit Incentive Plan In February 2021, the Company’s Parent adopted a written compensatory benefit plan (the “ Class B Unit Incentive Plan Incentive Units Tranche I Tranche II Tranche III The assumptions used in determining the fair value of the Incentive Units at the grant date are as follows: Volatility 57 % Risk-free interest rate 0.1 % Expected time to exit (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”) dated June 4, 2021. The Company’s Parent also amended the Class B Unit Incentive Plan so that the Tranche II Incentive Units will vest on any liquidation event, as defined in the Class B Unit Incentive Plan, rather than only upon the occurrence of an Exit Sale, subject to the market-based condition stipulated in the Class B Unit Incentive Plan prior to its amendment. 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: Volatility 46 % Risk-free interest rate 0.2 % Expected time to exit (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 Successor. 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. Additionally, the Company’s Parent modified the vesting conditions for three former employees. 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 three former employees 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 three former employees based on the modification date fair value. The incremental compensation cost recognized as a result of the modification was $4,572 during the year ended December 31, 2021. The total compensation expense recognized by the Company for Tranches I, II, and III Incentive Units, including the effects of the modification, was $60,349 during the year ended December 31, 2021, of which $53,463 was recognized in selling, general and administrative expense and $6,886 in cost of revenues. The table below presents the activity in the Class B Units: Unvested and outstanding as of January 1, 2021 — Granted 9,650,000 Vested (5,640,000 ) Forfeited (250,000 ) Unvested and outstanding as of December 31, 2021 3,760,000 As of December 31, 2021, there was approximately $22,713 of unrecognized compensation costs related to Tranche II Incentive Units. Stock Options On December 7, 2021, the Company adopted the BigBear.ai Holdings, Inc. 2021 Long-Term Incentive Plan (the “Plan”). The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by providing eligible employees, prospective employees, consultants, and non-employee The table below presents the activity in the Stock Options: Unvested and outstanding as of January 1, 2021 — Granted 482,000 Vested — Forfeited — Unvested and outstanding as of December 31, 2021 482,000 The fair value of the Options of $5.21 each is estimated on the grant date of December 7, 2021, using the Black-Scholes OPM using the following assumptions: Expected option term (years) 10 Expected volatility 54.0 % Risk-free rate of return 1.4 % Expected annual dividend yield — % As the Options are out of the money, the intrinsic value is zero. The Company recognizes equity-based compensation expense for the Options equal to the fair value of the awards on a straight-line basis over the service based vesting period. The Company recognized $42 and $1 in stock compensation expense in selling, general and administrative expense and cost of revenues, respectively, during the year ended December 31, 2021. As of December 31, 2021, there was approximately $2,471 of unrecognized compensation costs related to the Options. Restricted Stock Units On December 7, 2021, pursuant to the Plan, the Company’s Board of Directors communicated the key terms and committed to grant Restricted Stock Units (“RSUs”) to certain employees and nonemployee directors. The grant date of this award is December 7, 2021. The Company granted 273,300 RSUs to employees, 25% of which will vest on the first anniversary of the grant date, 25% on the second anniversary of the grant date, 25% on the third anniversary of the grant date, and 25% on the fourth anniversary of the grant date. The Company granted 130,000 RSUs to nonemployee directors, 100% of which will vest on the first anniversary of the grant date. Vesting of the RSUs is subject to the grantee’s continued service through the vesting date. The grant-date fair value of the RSUs was $10.03. 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.

(2) The Predecessor 2020 Period and Predecessor 2019 Period each comprise a single reportable segment. As a result, segment reporting for those periods is not presented. Contract Balances The table below presents the contract assets and contract liabilities included on the consolidated balance sheets for the following periods: Successor December 31, December 31, Contract assets $ 628 $ 2,575 Contract liabilities $ 4,207 $ 541 The change in contract assets between December 31, 2020 and December 31, 2021 was primarily driven by invoices being issued for services previously rendered for NuWave and ProModel. The change in contract liability balances between December 31, 2020 and December 31, 2021 was primarily driven by a large upfront payment related to an Analytics customer. Services on this contract will be performed over twelve months commencing in January 2022. Revenue recognized in the year ended December 31, 2021 that was included in the contract liability balance as of December 31, 2020 was $541. When the Company’s estimate of total costs to be incurred to satisfy a performance obligation exceeds the expected revenue, the Company recognizes the loss immediately. When the Company determines that a change in estimate has an impact on the associated profit of a performance obligation, the Company records the cumulative positive or negative adjustment in the consolidated statements of operations. Changes in estimates and assumptions related to the status of certain long-term contracts may have a material effect on the Company’s operating results. The following table summarizes the impact of the net estimates at completion “ EAC” adjustments on the Company’s operating results: Successor Year Ended December 31, Period from May 22, 2020 December 31, Net EAC Adjustments, before income taxes $ 1,650 $ — Net EAC Adjustments, net of income taxes $ 1,304 $ — Net EAC Adjustments, net of income taxes, per diluted share $ 0.01 $ — Remaining Performance Obligations The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders and generally includes the funded and unfunded contracts that have been awarded. As of December 31, 2021 (Successor), the aggregate amount of the transaction price allocated to remaining performance obligations was $159 million. The Company expects to recognize approximately 96% of its remaining performance obligations as revenue within the next 12 months and the balance thereafter.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	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.
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 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 minimum non-contingent rent
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 Software Costs incurred in developing internal-use
Equity-based Compensation	Equity-based Compensation Pursuant to ASC 718, Compensation – Stock Compensation recognizes equity-based compensation cost on a straight-line basis over the vesting period of the award. For 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.
