Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Xos, Inc. and its wholly owned subsidiaries (collectively, the “Company” or “Xos”) is a mobility solutions company. Xos manufactures Class 5 to 8 battery-electric commercial vehicles, facilitates fleet transition from traditional internal combustion engine vehicles to electric vehicles, and enables electric fleets to better manage their fleet operations through a portfolio of management tools. Xos developed the X-Platform (its proprietary, purpose-built vehicle chassis platform) and the X-Pack (its proprietary battery system) specifically for the medium- and heavy-duty commercial vehicle segment with a focus on last-mile commercial fleet operations. Xos’ “Fleet-as-a-Service” package offers customers a comprehensive suite of commercial products and services to facilitate electric fleet operations and seamlessly transition their traditional combustion-engine fleets to battery-electric vehicles. Xos Fleet, Inc. (“Legacy Xos”), the new legal entity name of the legacy Xos operating entity and Xos Services, Inc. (“Xos Services”, formerly Rivordak, Inc.), the subsidiary holding a California dealer license to sell Xos vehicles, are wholly owned subsidiaries of Xos, Inc., and make up 100% of the operations of the Company. Business Combination Xos, Inc. was initially incorporated on July 29, 2020 as a Cayman Islands exempted company under the name “NextGen Acquisition Corporation” (“NextGen”). On August 20, 2021, the transactions contemplated by the Agreement and Plan of Merger, as amended on May 14, 2021, by and among NextGen, Sky Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of NextGen (“Merger Sub”), and Xos, Inc., a Delaware corporation (now known as Xos Fleet, Inc., “Legacy Xos”), were consummated (the “Closing”), whereby Merger Sub merged with and into Legacy Xos, the separate corporate existence of Merger Sub ceased and Legacy Xos became the surviving corporation and a wholly owned subsidiary of NextGen (such transaction the “Merger” and, collectively with the Domestication, the “Business Combination”). As a result, Xos became the publicly traded entity listed on the Nasdaq Global Market. Emerging Growth Company Section 102(b)(1) of the Jumpstart its Business Startups Act (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a registration statement declared effective pursuant to the Securities Act of 1933, as amended (the “Securities Act”), or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard, until such time the Company is no longer considered to be an emerging growth company. At times, the Company may elect to early adopt a new or revised standard. Risks and Uncertainties COVID-19 and actions taken to mitigate its spread have had and may continue to have an adverse impact on the economies and financial markets of many countries, including the areas in which the Company operates. As the COVID-19 pandemic continues to evolve, the Company believes the extent of the pandemic’s impact to its business, operating results, cash flows, liquidity and financial condition will be primarily driven by the severity and duration of the COVID-19 pandemic, the pandemic’s impact on the United States and global economies and the timing, scope and effectiveness of federal, state and local governmental responses to the pandemic. Those primary drivers are beyond the Company’s knowledge and control, and as a result, at this time the Company is unable to predict the cumulative impact, both in terms of severity and duration, that the COVID-19 pandemic will have on its business, operating results, cash flows and financial condition. However, the impact of the COVID-19 pandemic could be material if the current circumstances continue to exist for a prolonged period of time or worsen. Additionally, recent geopolitical events, such as the recent military conflict between Russia and Ukraine, may increase the severity of supply chain disruptions and further hinder our ability to source inventory for our vehicles. The conflict continues to evolve and its ultimate impact on the Company is uncertain, but a prolonged conflict may have a material negative impact on the Company’s business, operating results, cash flows, liquidity and financial condition. Although the Company has used the best current information available to it in its estimates, actual results could materially differ from the estimates and assumptions developed by management. Supply Chain Disruptions Negative global economic conditions, which the COVID-19 pandemic has contributed to, has impacted the Company’s ability to source certain critical inventory items. The series of restrictions imposed and the speed and nature of the recovery in response to the pandemic have placed burdens on the Company’s supply chain management, such as the semiconductor chip and battery cell shortage and supply limitations on vehicle bodies and aluminum. Despite supply chain disruptions, the Company has continued to source inventory for its vehicles and its purchasing team has been working with vendors to find alternative solutions to areas where there are supply chain constraints, and where appropriate and critical, has placed orders in advance of projected need to ensure inventory is able to be delivered in time for production plans.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies The following is a summary of the significant accounting policies consistently applied in the preparation of the accompanying unaudited condensed consolidated financial statements: Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. They do not include all of the information and footnotes required by U.S. GAAP for complete audited financial statements. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Legacy Xos and Xos Services. All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (primarily consisting of normal accruals) considered for a fair presentation have been included. Operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 30, 2022. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the balance sheet date, as well as reported amounts of revenues and expenses during the reporting periods. The areas with significant estimates and judgments include, among others, inventory valuation, incremental borrowing rates for assessing operating and financing lease liabilities, useful lives of property and equipment, earn-out shares liability, stock-based compensation, common stock warrant liability and product warranty liability. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates, and such differences could be material to the Company’s condensed consolidated financial statements. Reclassifications Certain prior p eriod balances have been reclassified to conform to the current period presentation in the unaudited condensed consolidated financial statements and the accompanying notes , including (i) classification of operating expenses in the unaudited condensed consolidated statements of operations and comprehensive loss and (ii) presenting equipment leases as part of other current and non-current liabilities. The Company reclassified a portion of its payroll related expenses in general and administrative to sales and marketing and research and development. Additionally, the Company reclassified depreciation expense to general and administrative expense. These reclassifications have no effect on previously reported net loss. Inventory and Inventory Valuation The Company’s inventory, which includes raw materials, work in-process, and finished goods, is carried at the lower of cost or net realizable value (“NRV”). Inventory is valued using average costing, as that method accurately reflects the frequency of the Company’s inventory purchases. In the case of manufactured inventories and work in progress, cost includes an appropriate share of production overheads based on operating capacity. At the end of each reporting period, the Company evaluates whether its inventories are damaged, obsolete, or have material changes in price or other causes, and if so, a loss is recognized in the period in which it occurs. Inventory write-downs are also based on reviews for obsolescence determined primarily by future demand forecasts. If the Company’s inventory on-hand is in excess of future demand forecast, the excess amounts are written-off. The Company reserves for any excess or obsolete inventories when it is believed that the net realizable value of inventories is less than the carrying value. The Company also reviews its inventory to determine whether its carrying value exceeds the net amount realizable upon the ultimate sale of the inventory. NRV is the estimated selling price of inventory in the ordinary course of business, less estimated costs of completion, disposal, and transportation. At the end of each reporting period, the Company determines the estimated selling price of its inventory based on market conditions. Once inventory is written-down, a new, lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Warranty Liability Since 2021, the Company provides customers with a product warranty that assures that the products meet standard specifications and are free for periods typically between 2 to 5 years. The Company accrues warranty reserve for the products sold, which includes its best estimate of the projected costs to repair or replace items under warranties and recalls if identified. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the Company’s relatively short history of sales, and changes to its historical or projected warranty experience may cause material changes to the warranty reserve in the future. Claims incurred under the Company’s standard product warranty programs are recorded based on open claims. Claims incurred in each of the three and six months ended June 30, 2022 were $6,000, respectively; no claims were incurred for the year ended December 31, 2021. The Company recorded warranty liability within other current liabilities in the consolidated balance sheets as of June 30, 2022 and December 31, 2021. The Company did not record warranty liability for the three or six months ended June 30, 2021 as the product warranty had not been established. The reconciliation of the change in the Company’s product liability balances during the three months and six months ended June 30, 2022 consisted of the following (in thousands) : Three Months Ended June 30, 2022 Six Months Ended June 30, 2022 Warranty liability, beginning of period $ 475 $ 177 Reduction in liability (payments) (6) (6) Increase in liability (new warranties) 363 661 Warranty liability, end of period $ 832 $ 832 Leases Upon inception of a contract, the Company evaluates if the contract, or part of the contract, contains a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The lease liability is measured as the present value of the unpaid lease payments, and the ROU asset value is derived from the calculation of the lease liability, including prepaid lease payments, if any. Lease payments include fixed and in-substance fixed payments, variable payments based on an index or rate, reasonably certain purchase options, termination penalties, fees paid by the lessee to the owners of a special-purpose entity for restructuring the transaction, and probable amounts the lessee will owe under a residual value guarantee. Lease payments do not include (i) variable lease payments other than those that depend on an index or rate, (ii) any guarantee by the lessee of the lessor’s debt, or (iii) any amount allocated to non-lease components, if such election is made upon adoption, per the provisions of ASU 2016-02, Leases. When the Company cannot determine the actual implicit rate in a lease, it uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. The Company gives consideration to its recent debt issuances, if any, as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rate. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company's lease term includes any option to extend the lease when it is reasonably certain to be exercised based on considering all relevant economic factors. Operating expense charges from the lessor are accounted for on an accrual basis. The Company has elected not to separate the lease and non-lease components. The leases have remaining initial terms ranging from less than 1 year to 5 years . The Company reviews the carrying value of its right-of-use assets for impairment whenever events or changes in circumstances indicate that the recorded value may not be recoverable. Recoverability of assets is measured by comparing the carrying amounts of the assets to the estimated future undiscounted cash flows, excluding financing costs. If the Company determines that an impairment exists, any related impairment loss is estimated based on fair values. Recent Accounting Pronouncements Issued and Adopted: ASC 842, Leases : In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as subsequently amended, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors), and replaces the existing guidance in ASC 840, Leases . The new standard also requires lessees to recognize operating and finance lease liabilities and corresponding ROU assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. On January 1, 2022, the Company adopted ASC 842 using the modified retrospective method. The Company has presented financial results and applied its accounting policies for the period beginning January 1, 2022 under ASC 842, while prior period results and accounting policies have not been adjusted and are reflected under legacy GAAP pursuant to ASC 840. In connection with the adoption of ASC 842, the Company performed an analysis of contracts under ASC 840 to ensure proper assessment of leases (or embedded leases) in existence as of January 1, 2022. The Company elected the package of practical expedients permitted under ASC 842, which allows the Company not to reassess 1) whether any expired or existing contracts as of the adoption date are or contain a lease, 2) lease classification for any expired or existing leases as of the adoption date and 3) initial direct costs for any existing leases as of the adoption date. The most significant impact of applying ASC 842 was the recognition of ROU asset and lease liabilities for operating leases in its condensed consolidated balance sheets. On January 1, 2022, the Company recognized an initial operating ROU asset of $7.7 million and associated operating lease liab ilities of $7.7 million . Refer to Note 6 — Leases for further information regarding the impact of the adoption of ASU 2016-02 on the Company's financial statements, as well as its various accounting policies for each lease type. Recent Accounting Pronouncements Issued and not yet Adopted: ASU 2016-13, Financial Instruments — Credit Losses (“ASU 2016-13”): In June 2016, the FASB issued ASU 2016-13, which states the Company will be required to use an expected-loss model for its marketable debt securities, available-for sale, which requires that credit losses be presented as an allowance rather than as an impairment write-down. Reversals of credit losses (in situations in which the estimate of credit losses declines) is permitted in the reporting period that the change occurs. Current U.S. GAAP prohibits reflecting reversals of credit losses in current period earnings. At June 30, 2022 , the Company had $77.9 million in marketable debt securities, available for sale which would be subject to this new standard. As of December 31, 2021, these marketable debt securities, available for sale have an average credit rating of A and no impairment write-downs have been recorded. The Company is currently evaluating the impact of this new standard on its investment policy and investments and does not expect the standard to have a material impact on its financial statements at adoption or in subsequent periods. The Company expects to adopt the new standard effective January 1, 2023 .

Business Combination and Asset Acquisition [Abstract]
Recapitalization and Contingent Earn-out Shares Liability	Recapitalization and Earn-out Shares Liability Recapitalization As discussed in Note 1, on August 20, 2021, Legacy Xos and NextGen consummated the Business Combination contemplated by the Merger Agreement. Xos has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances: • Xos stockholders have the largest voting interest in the post-combination company; • The board of directors of Xos is authorized to be up to nine members and had six members designated at the time of closing, and Xos having the ability to nominate the majority of the members of the board of directors as of closing; • Xos management holds executive management roles (including Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, and Chief Technology Officer, among others) for the post-combination company and is responsible for the day-to-day operations; • The post-combination company assumed the Xos name: “Xos, Inc.”; and • The intended strategy of the post-combination entity continued Legacy Xos’ strategy of being a leader in the electric vehicle industry. Accordingly, all historical financial information presented in these combined and consolidated financial statements represents the accounts of Legacy Xos and its wholly owned subsidiaries “as if” Legacy Xos is the predecessor and legal successor. The historical operations of Legacy Xos are deemed to be those of the Company. Thus, the financial statements included in this report reflect (i) the historical operating results of Legacy Xos prior to the business combination; (ii) the combined results of NextGen and Legacy Xos following the Business Combination; and (iii) the assets and liabilities of Legacy Xos at their historical cost. No step-up basis of intangible assets or goodwill was recorded in the business combination transaction consistent with the treatment of the transaction as a reverse capitalization. In connection with the Business Combination, each share of Legacy Xos Common Stock and Legacy Xos Preferred Stock issued and outstanding immediately prior to the Business Combination (with each share of Legacy Xos Preferred Stock being treated as if it were converted into Legacy Xos Common Stock immediately prior to the Business Combination) converted into the right to receive 1.956440 shares (the “Exchange Ratio”) of Common Stock. Also, in connection with the Business Combination, the following occurred: • the merger of Legacy Xos into a wholly owned subsidiary of NextGen, with Legacy Xos surviving the merger as a wholly owned subsidiary of NextGen, with the combined company is referred to as “Xos”; • 142,584,621 shares of Common Stock issued, including: (i) the Legacy Xos’ Common Stock, and (ii) Legacy Xos’ Preferred Stock, including the exercise and conversion of Legacy Xos’ Preferred Stock warrant (as if the Legacy Xos Preferred Stock had converted into the Legacy Xos’ Common Stock immediately prior to the reverse merger); • the issuance and sale of 19,600,000 shares of Common Stock (PIPE investment) for a purchase price of $10.00 per share and an aggregate purchase price of $196.0 million (which excludes the sale of 2,000,000 shares in the aggregate for a purchase price of $10.00 per share and an aggregate purchase price of $20.0 million pursuant to an offering of Common Stock by the Founders of Legacy Xos). On the Closing Date, one of the PIPE Investors, Grantchester C Change, LLC., did not fund their $4.0 million committed amount under the binding Subscription Agreement.; • the settlement of the outstanding underwriting fees incurred in connection with the initial public offering of NextGen on October 9, 2020, for which the final cash amount owed was $11.2 million; • the settlement of the direct and incremental transaction costs incurred prior to, or concurrent with, the closing of the business combination in the amount of $44.2 million, which are recorded as reduction to additional paid-in capital; • the recognition of contingent earn-out interests provision as liability with a fair value of $101.7 million on the day of the merger consummation; and, • the assumption of the Public Warrants (12,499,964 units) and Private Placement Warrants (6,333,334 units) at fair value of $17.9 million on the day of merger consummation. Contingent Earn-out Shares Liability The Company has a contingent obligation to issue 16.2 million shares (the “Earn-out Shares”) of Common Stock and grant 261,000 restricted stock units (“Earn-out RSUs”) to certain stockholders and employees upon the achievement of certain market share price milestones within specified periods following the Business Combination on August 20, 2021. The Earn-out Shares will be issued in tranches based on the following conditions: i. If the volume-weighted average closing share price (“VWAP”) of the Common Stock equals or exceeds $14.00 per share for any 10 trading days within any consecutive 20-trading day period between the merger closing date and the five year anniversary of such closing date (“Earn-out Period”), then the Company is required to issue an aggregate of 5.4 million shares (“Tranche 1 Earn-out Shares”) of Common Stock to holders with the contingent right to receive Earn-out Shares (excluding any Earn-out RSUs). If after Closing and during the Earn-out Period, there is a Change in Control (as defined in the Merger Agreement), the Company is required to issue Tranche 1 Earn-out Shares when the value per share of the Company is equal to or greater than $14.00 per share, but less than $20.00. If there is a change in control where the value per share of commons stock is less than $14.00, then the Earn-out Shares shall terminate prior to the end of the Earn-out Period and no common stock shall be issuable. ii. If the VWAP of the Common Stock equals or exceeds $20.00 per share for any 10 trading days within any consecutive 20-trading day period during the Earn-out Period, then the Company is required to issue an aggregate of 5.4 million shares (“Tranche 2 Earn-out Shares”) of Common Stock to holders with the contingent right to receive Earn-out Shares (excluding any Earn-out RSUs). If after Closing and during the Earn-out Period, there is a Change in Control (as defined in the Merger Agreement), the Company is required to issue Tranche 2 Earn-out Shares when the value per share of the Company is equal to or greater than $20.00 per share, but less than $25.00. iii. If the VWAP of the Common Stock equals or exceeds $25.00 per share for any 10 trading days within any consecutive 20-trading day period during the Earn-out Period, then the Company is required to issue an aggregate of 5.4 million shares (“Tranche 3 Earn-out Shares”) of Common Stock to holders with the contingent right to receive Earn-out Shares (excluding any Earn-out RSUs). If after Closing and during the Earn-out Period, there is a Change in Control (as defined in the Merger Agreement), the Company is required to issue Tranche 3 Earn-out Shares when the valuer per share of the Company is equal to or greater than $25.00 per share. Pursuant to the guidance under ASC 815, Derivatives and Hedging, the right to Earn-out Shares was classified as a Level 3 fair value measurement liability, and the increase or decrease in the fair value during the reporting period is recognized in the condensed consolidated statement of operations accordingly. The fair value of the Earn-out Shares liability was estimated using the Monte Carlo simulation of the stock prices based on historical and implied market volatility of a peer group of public companies. The Company recognized a gain on the fair value change in Earn-out Shares liability of $14.9 million and $17.5 million in its unaudited condensed consolidated statements of operations during the three and six months ended June 30, 2022, respectively.

Stockholders' Equity Note And Temporary Equity [Abstract]
Equity	Equity Xos Common and Preferred Stock The Company is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares which the Company is authorized to issue is 1,010,000,000 shares. 1,000,000,000 shares shall be Common Stock, each having a par value of one-hundredth of one cent ($0.0001). 10,000,000 shares shall be Preferred Stock, each having a par value of one-hundredth of one cent ($0.0001). Voting Rights : Each outstanding share of Common Stock shall entitle the holder thereof to one vote on each matter properly submitted to the stockholders of the Company for their vote; provided, however, that, except as otherwise required by law, holders of Common Stock shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any certificate of designation filed with respect to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon by law or pursuant to this Certificate of Incorporation (including any certificate of designation filed with respect to any series of Preferred Stock). Preferred Stock : The Preferred Stock may be issued from time to time in one or more series. The Board of Directors of the Company (the “Board of Directors”) is hereby expressly authorized to provide for the issue of all or any number of the shares of the Preferred Stock in one or more series, and to fix the number of shares and to determine or alter for each such series, such voting powers, full or limited, or no voting powers, and such designation, preferences, and relative, participating, optional, or other rights and such qualifications, limitations, or restrictions thereof, as shall be stated and expressed in the resolution or resolutions adopted by the Board of Directors providing for the issuance of such shares and as may be permitted by the Delaware General Corporation Law (the “DGCL”). The Board of Directors is also expressly authorized to increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series subsequent to the issuance of shares of that series. In case the number of shares of any series shall be decreased in accordance with the foregoing sentence, the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series. Legacy Xos’ Preferred Stock During the fourth quarter of 2020, Legacy Xos executed a financing round and issued shares of preferred stock (the “Series A Financing’’). The Series A Financing included the authorization of 25,794,475 shares of Legacy Xos Preferred Stock in classes A through A-10. The shares of Class A Legacy Xos Preferred Stock were allocated to investors who contributed new money to Legacy Xos, while the shares of Class A-1 through A-10 Legacy Xos Preferred Stock were issued in exchange to convertible note holders. As part of this raise, 1,411,764 shares of Class A Legacy Xos Preferred Stock and one warrant exercisable for 319,411 shares of Class A Legacy Xos Preferred Stock were issued for aggregate cash proceeds of $9.6 million and a subscription receivable for $2.4 million. During the quarter ended March 31, 2021, the Legacy Xos issued an additional 3,739,846 shares of Class A Legacy Xos Preferred Stock raising $31.8 million in cash proceeds, and the conversion of the SAFE agreement (Simple Agreement for Future Equity) issued to Elemental Excelerator (the “SAFE Note”). As part of this transaction, Legacy Xos converted $21.5 million of convertible notes and $2.5 million in accrued interest into 21,570,308 shares of Class A-1 through A-10 Legacy Xos Preferred Stock. These exchanges from convertible notes into shares of Legacy Xos Preferred Stock included transactions with both related and unrelated parties (refer to Note 14). The differences between the total carrying value of the converted notes held by third parties, and the fair value of the issued shares of Legacy Xos Preferred stock, was recorded as realized loss on debt extinguishment in the consolidated statement of operations. We have determined the fair value of the issued shares of Legacy Xos Preferred Stock in connection with the note conversion using market rates experienced in other non-related party transactions, through the issuance of shares of Legacy Xos Preferred Stock. As some of the converted third-party notes have voting rights and others do not, the fair value of non-voting shares were reduced by 3%. Concurrent with the Business Combination, outstanding shares of Legacy Xos Preferred Stock were converted into shares of Common Stock in accordance with the Exchange Ratio. Standby Equity Purchase Agreement On March 23, 2022, the Company entered into a Standby Equity Purchase Agreement (the "SEPA") with YA II PN, Ltd. (“Yorkville”), whereby the Company has the right, but not the obligation, to sell to Yorkville up to $125.0 million of shares of its Common Stock at its request any time during the 36 months following the execution of the SEPA, subject to certain conditions. The Company expects to use any net proceeds for working capital and general corporate purposes. As consideration for Yorkville’s commitment to purchase shares of common stock at the Company’s direction upon the terms and subject to the conditions set forth in the purchase agreement, upon execution of the purchase agreement, the Company issued 18,582 shares of common stock to Yorkville. During the three months ended June 30, 2022, the Company issued 1,809,515 shares of Common Stock under the SEPA for proceeds of $4.3 million. As of June 30, 2022, the remaining commitment available under the agreement was $120.7 million.

Derivative Instruments	Derivative Instruments Public and Private Placement Warrants As of June 30, 2022, the Company had 18,613,299 Public Warrants and 219,999 Private Placement Warrants outstanding, with fair values of $4.2 million and $49,000, respectively. The Public Warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire on August 20, 2026 or earlier upon redemption or liquidation. The Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the units and only whole Public Warrants will trade. The Public Warrants became exercisable; provided that the Company has an effective registration statement under the Securities Act covering the issuance of the Common Stock issuable upon exercise of the Warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permits holders to exercise their Warrants on a cashless basis under the circumstances specified in the warrant agreement). A registration statement was filed with the SEC covering the issuance of the Common Stock issuable upon exercise of the Warrants, and the Company will use its commercially reasonable efforts to maintain the effectiveness of such registration statement and a current prospectus relating to those shares of Common Stock until the Public Warrants expire or are redeemed. If the shares of Common Stock are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, requires holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, it will not be required to file or maintain in effect a registration statement. The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the Common Stock issuable upon exercise of the Private Placement Warrants were not transferable, assignable or salable until September 19, 2021, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial shareholders or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. Redemption of Warrants for cash when the price per Common Stock equals or exceeds $18.00: Once the Warrants become exercisable, the Company may redeem the outstanding Warrants (except as described above with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per Warrant; • upon not less than 30 days’ prior written notice of redemption to each Warrant holder; and • if, and only if, the last reported sale price of Common Stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the Warrant holders (the “Reference Value”) equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share dividends, rights issuances, consolidations, reorganizations, recapitalizations and the like). The Company will not redeem the Warrants as described above unless a registration statement under the Securities Act covering the issuance of the Common Stock issuable upon exercise of the Warrants is then effective and a current prospectus relating to those Common Stock is available throughout the 30-day redemption period. If and when the Warrants become redeemable by the Company, it may exercise its redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of Warrants for Common Stock when the price per share equals or exceeds $10.00: Once the Warrants become exercisable, the Company may redeem the outstanding Warrants (including both Public Warrants and Private Placement Warrants): • in whole and not in part; • at $0.10 per Warrant upon a minimum of 30 days’ prior written notice of redemption provided that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to an agreed table based on the redemption date and the “fair market value” of Common Stock; • if, and only if, the Reference Value equals or exceeds $10.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like); and • if the Reference Value is less than $18.00 per share (as adjusted), the Private Placement Warrants must also concurrently be called for redemption on the same terms as the outstanding Public Warrants, as described above. The “fair market value” of Common Stock shall mean the average reported last sale price of Common Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of Warrants. In no event will the Company be required to net cash settle any Warrant. The Warrants may also expire worthless.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate during the three months ended June 30, 2022 and 2021 was (0.01)% and 0%, respectively. The effective tax rate during the six months ended June 30, 2022 and 2021 was (0.01)% and 0%, respectively. State taxes coupled with losses not benefited resulted in an effective tax rate, below the statutory tax rate of 21% for the six months ended June 30, 2022. The Company recognizes tax benefits related to positions taken, or expected to be taken, on its tax returns, only if the positions are "more-likely-than-not" sustainable. Once this threshold has been met, the Company's measurement of its expected tax benefits is recognized in its financial statements. The Company does not have any uncertain tax positions that meet this threshold as of June 30, 2022 and December 31, 2021. The Company files income tax returns with the Internal Revenue Service and the taxing authorities of various states. The tax periods 2018 through 2021 remain open in most jurisdictions. The Company is not currently under examination by income tax authorities in any federal or state jurisdiction. At June 30, 2022, the Company's deferred income taxes were in a net asset position mainly due to deferred tax assets generated by net operating losses. The Company assesses the likelihood that its deferred tax assets will be realized. A full review of all positive and negative evidence needs to be considered, including the Company's current and past performance, the market environments in which the Company operates, the utilization of past tax credits, length of carryback and carryforward periods, as well as tax planning strategies that might be implemented. Management believes that, based on a number of factors, it is more likely than not, that all or some portion of the deferred tax assets may not be realized; and accordingly, for the periods ended June 30, 2022 and 2021, the Company has provided a valuation allowance against net US deferred tax assets.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures , clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. U.S. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. As presented in the tables below, this hierarchy consists of three broad levels: • Level 1: Quoted prices in active markets for identical assets and liabilities. • Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model-derived valuations whose inputs or significant value drivers are observable. • Level 3: Significant inputs to the valuation model are unobservable and significant to the overall fair value measurement of the assets or liabilities. Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, investments in marketable debt securities, available-for-sale, accounts payable, other current liabilities, public and private placement warrants, and the contingent earn-out shares liability. The fair value of cash and accounts receivable approximates carrying value due to their short-term maturity. As required by ASC 820, assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Derivative financial instruments which are required to be measured at fair value on a recurring basis are measured at fair value using Level 3 inputs for all periods presented. Level 3 inputs are unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities carried at fair value on a recurring basis as of June 30, 2022 and December 31, 2021 consisted of the following (in thousands) : June 30, 2022 Fair Value Level 1 Level 2 Level 3 Financial Assets Cash and Cash Equivalents (1) : Money market funds $ 2,207 $ 2,207 $ — $ — $ 2,207 $ 2,207 $ — $ — Short-Term Investments: U.S. treasuries $ 5,534 $ 5,534 $ — $ — Corporate debt security 42,250 — 42,250 — Asset-backed security and other 5,791 — 5,791 — Non-U.S. government and supranational bonds 9,072 — 9,072 — Certificate of Deposit 2,004 — 2,004 — $ 64,651 $ 5,534 $ 59,117 $ — Long-Term Investments: Corporate debt security $ 11,231 $ — $ 11,231 $ — Asset-backed security and other 1,987 — 1,987 — $ 13,218 $ — $ 13,218 $ — Total Financial Assets $ 80,076 $ 7,741 $ 72,335 $ — Financial Liabilities: Private Placement Warrants $ 49 $ — $ 49 $ — Public Warrants 4,178 4,178 — — Contingent Earn-out Shares liability 11,894 — — 11,894 Total Financial Liabilities $ 16,121 $ 4,178 $ 49 $ 11,894 ____________ (1) Included in total cash and cash equivalents in the condensed consolidated balance sheets.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company evaluated all events or transactions that occurred through August 11, 2022, t he date the condensed consolidated financial statements were issued. Convertible Debentures On Augus t 9, 2022, the Company entered into a securities purchase agreement with Yorkville for the issuance of convertible debentures in the principal amount of up to $35.0 million (the “Convertible Debentures”). $20.0 million in principal amount of Convertible Debentures was issued on August 11, 2022, and an additional $15.0 million in principal amount will be issued to Yorkville upon the effectiveness of the registration statement registering the resale of Common Stock resulting from the conversion of the Convertible Debentures. The maturity date of the Convertible Debentures shall be November 11, 2023, which may be extended by an additional three months in certain instances. The Convertible Debentures bear interest at an annual rate of 6.0%, payable at maturity, which will increase to an annual rate of (i) 10.0% upon the occurrence and during the continuance of an event of default, and (ii) 7.5% for so long as “Registration Event” (as defined in the Convertible Debenture) remains in effect in accordance with the registration rights agreement. The Convertible Debentures provide a conversion right, in which Yorkville may, at any time after the issuance date, convert any portion of the principal amount of the Convertible Debenture, together with any accrued but unpaid interest, into shares of Common Stock at the lower of (i) $2.4733 per share or (ii) 97% of the lowest daily volume weighted average price of the Common Stock during the three trading days immediately preceding the date of conversion (but not lower than a floor price of $0.50 per share, subject to adjustment in accordance with the terms of the Convertible Debentures). Convertible Notes On August 9, 2022, the Company entered into an agreement with Aljomaih Automotive Co. (“Aljomaih”) for the issuance of convertible note with a principal amount of $20.0 million and a maturity date of August 11, 2025 (the “Note”). The Note includes an option to issue and sell additional convertible notes in a principal amount of up to an additional $20.0 million, upon the mutual consent of both parties by November 30, 2022, on terms and conditions to be negotiated in good faith. The Note bears interest at a rate of 10.0% per annum, payable at maturity in validly issued, fully paid and non-assessable shares of Common Stock, calculated based on the 10-day volume weighted average price ending on the trading day immediately prior to the applicable payment date, unless earlier converted or paid. The conversion price for the Note will initially be equal to $2.3817 per share, subject to adjustment in some events pursuant to the terms of the Note.

Business Combination	Xos, Inc. was initially incorporated on July 29, 2020 as a Cayman Islands exempted company under the name “NextGen Acquisition Corporation” (“NextGen”). On August 20, 2021, the transactions contemplated by the Agreement and Plan of Merger, as amended on May 14, 2021, by and among NextGen, Sky Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of NextGen (“Merger Sub”), and Xos, Inc., a Delaware corporation (now known as Xos Fleet, Inc., “Legacy Xos”), were consummated (the “Closing”), whereby Merger Sub merged with and into Legacy Xos, the separate corporate existence of Merger Sub ceased and Legacy Xos became the surviving corporation and a wholly owned subsidiary of NextGen (such transaction the “Merger” and, collectively with the Domestication, the “Business Combination”). As a result, Xos became the publicly traded entity listed on the Nasdaq Global Market.
Emerging Growth Company	Section 102(b)(1) of the Jumpstart its Business Startups Act (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a registration statement declared effective pursuant to the Securities Act of 1933, as amended (the “Securities Act”), or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard, until such time the Company is no longer considered to be an emerging growth company. At times, the Company may elect to early adopt a new or revised standard.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. They do not include all of the information and footnotes required by U.S. GAAP for complete audited financial statements. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Legacy Xos and Xos Services. All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (primarily consisting of normal accruals) considered for a fair presentation have been included. Operating results for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 30, 2022.
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the balance sheet date, as well as reported amounts of revenues and expenses during the reporting periods. The areas with significant estimates and judgments include, among others, inventory valuation, incremental borrowing rates for assessing operating and financing lease liabilities, useful lives of property and equipment, earn-out shares liability, stock-based compensation, common stock warrant liability and product warranty liability. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates, and such differences could be material to the Company’s condensed consolidated financial statements.
Reclassifications	Certain prior p eriod balances have been reclassified to conform to the current period presentation in the unaudited condensed consolidated financial statements and the accompanying notes , including (i) classification of operating expenses in the unaudited condensed consolidated statements of operations and comprehensive loss and (ii) presenting equipment leases as part of other current and non-current liabilities. The Company reclassified a portion of its payroll related expenses in general and administrative to sales and marketing and research and development. Additionally, the Company reclassified depreciation expense to general and administrative expense. These reclassifications have no effect on previously reported net loss.
Inventory and Inventory Valuation	The Company’s inventory, which includes raw materials, work in-process, and finished goods, is carried at the lower of cost or net realizable value (“NRV”). Inventory is valued using average costing, as that method accurately reflects the frequency of the Company’s inventory purchases. In the case of manufactured inventories and work in progress, cost includes an appropriate share of production overheads based on operating capacity. At the end of each reporting period, the Company evaluates whether its inventories are damaged, obsolete, or have material changes in price or other causes, and if so, a loss is recognized in the period in which it occurs. Inventory write-downs are also based on reviews for obsolescence determined primarily by future demand forecasts. If the Company’s inventory on-hand is in excess of future demand forecast, the excess amounts are written-off. The Company reserves for any excess or obsolete inventories when it is believed that the net realizable value of inventories is less than the carrying value. The Company also reviews its inventory to determine whether its carrying value exceeds the net amount realizable upon the ultimate sale of the inventory. NRV is the estimated selling price of inventory in the ordinary course of business, less estimated costs of completion, disposal, and transportation. At the end of each reporting period, the Company determines the estimated selling price of its inventory based on market conditions. Once inventory is written-down, a new, lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.
Warranty Liability	Since 2021, the Company provides customers with a product warranty that assures that the products meet standard specifications and are free for periods typically between 2 to 5 years. The Company accrues warranty reserve for the products sold, which includes its best estimate of the projected costs to repair or replace items under warranties and recalls if identified. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the Company’s relatively short history of sales, and changes to its historical or projected warranty experience may cause material changes to the warranty reserve in the future. Claims incurred under the Company’s standard product warranty programs are recorded based on open claims. Claims incurred in each of the three and six months ended June 30, 2022 were $6,000, respectively; no claims were incurred for the year ended December 31, 2021. The Company recorded warranty liability within other current liabilities in the consolidated balance sheets as of June 30, 2022 and December 31, 2021. The Company did not record warranty liability for the three or six months ended June 30, 2021 as the product warranty had not been established.
Leases	Upon inception of a contract, the Company evaluates if the contract, or part of the contract, contains a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The lease liability is measured as the present value of the unpaid lease payments, and the ROU asset value is derived from the calculation of the lease liability, including prepaid lease payments, if any. Lease payments include fixed and in-substance fixed payments, variable payments based on an index or rate, reasonably certain purchase options, termination penalties, fees paid by the lessee to the owners of a special-purpose entity for restructuring the transaction, and probable amounts the lessee will owe under a residual value guarantee. Lease payments do not include (i) variable lease payments other than those that depend on an index or rate, (ii) any guarantee by the lessee of the lessor’s debt, or (iii) any amount allocated to non-lease components, if such election is made upon adoption, per the provisions of ASU 2016-02, Leases. When the Company cannot determine the actual implicit rate in a lease, it uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. The Company gives consideration to its recent debt issuances, if any, as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rate. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company's lease term includes any option to extend the lease when it is reasonably certain to be exercised based on considering all relevant economic factors. Operating expense charges from the lessor are accounted for on an accrual basis. The Company has elected not to separate the lease and non-lease components. The leases have remaining initial terms ranging from less than 1 year to 5 years . The Company reviews the carrying value of its right-of-use assets for impairment whenever events or changes in circumstances indicate that the recorded value may not be recoverable. Recoverability of assets is measured by comparing the carrying amounts of the assets to the estimated future undiscounted cash flows, excluding financing costs. If the Company determines that an impairment exists, any related impairment loss is estimated based on fair values.
Recent Accounting Pronouncements Issued and Adopted and Recent Accounting Pronouncements Issued and Not Yet Adopted	ASC 842, Leases : In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as subsequently amended, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors), and replaces the existing guidance in ASC 840, Leases . The new standard also requires lessees to recognize operating and finance lease liabilities and corresponding ROU assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. On January 1, 2022, the Company adopted ASC 842 using the modified retrospective method. The Company has presented financial results and applied its accounting policies for the period beginning January 1, 2022 under ASC 842, while prior period results and accounting policies have not been adjusted and are reflected under legacy GAAP pursuant to ASC 840. In connection with the adoption of ASC 842, the Company performed an analysis of contracts under ASC 840 to ensure proper assessment of leases (or embedded leases) in existence as of January 1, 2022. The Company elected the package of practical expedients permitted under ASC 842, which allows the Company not to reassess 1) whether any expired or existing contracts as of the adoption date are or contain a lease, 2) lease classification for any expired or existing leases as of the adoption date and 3) initial direct costs for any existing leases as of the adoption date. The most significant impact of applying ASC 842 was the recognition of ROU asset and lease liabilities for operating leases in its condensed consolidated balance sheets. On January 1, 2022, the Company recognized an initial operating ROU asset of $7.7 million and associated operating lease liab ilities of $7.7 million . Refer to Note 6 — Leases for further information regarding the impact of the adoption of ASU 2016-02 on the Company's financial statements, as well as its various accounting policies for each lease type. Recent Accounting Pronouncements Issued and not yet Adopted: ASU 2016-13, Financial Instruments — Credit Losses (“ASU 2016-13”): In June 2016, the FASB issued ASU 2016-13, which states the Company will be required to use an expected-loss model for its marketable debt securities, available-for sale, which requires that credit losses be presented as an allowance rather than as an impairment write-down. Reversals of credit losses (in situations in which the estimate of credit losses declines) is permitted in the reporting period that the change occurs. Current U.S. GAAP prohibits reflecting reversals of credit losses in current period earnings. At June 30, 2022 , the Company had $77.9 million in marketable debt securities, available for sale which would be subject to this new standard. As of December 31, 2021, these marketable debt securities, available for sale have an average credit rating of A and no impairment write-downs have been recorded. The Company is currently evaluating the impact of this new standard on its investment policy and investments and does not expect the standard to have a material impact on its financial statements at adoption or in subsequent periods. The Company expects to adopt the new standard effective January 1, 2023 .
