We have based these forward-looking statements on our current expectations and projections about future events. All statements, other than statements of present or historical fact included in this Report are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “will,” “would” or the negative of such terms or other similar expressions. These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. We caution you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond our control.

As a result of a number of known and unknown risks and uncertainties, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:

3

•our ability to successfully manage supply shortages and disruptions, product delivery delays, and anticipate costs and production timing in light of those challenges;

•our ability to scale in a cost-effective manner, including hiring qualified personnel, particularly during recent labor shortages, to meet our manufacturing and delivery goals;

•developments and projections relating to our competitors and industry;

•general economic and political conditions, such as the effects of the COVID-19 pandemic, recessions, interest rates, inflation, local and national elections, fuel prices, international currency fluctuations, corruption, political instability and acts of war or military conflict, including repercussions of the recent military conflict between Russia and Ukraine, or terrorism on our business and the actions we may take in response thereto;

•our expectations regarding our ability to obtain and maintain intellectual property protection and not infringe on the rights of others;

In light of the significant uncertainties inherent in the forward-looking statements included herein, the inclusion of such information should not be regarded as a representation by us or any other person that the results or conditions described in such statements or our objectives and plans will be achieved.

Forward-looking statements and such risks, uncertainties and other factors speak only as of the date of this Report, and we expressly disclaim any obligation or undertaking to update or revise any forward-looking statement contained herein to reflect any change in our expectations with regard thereto, or any other change in events, conditions or circumstances on which any such statement is based, except to the extent otherwise required by law.

Note 1— 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.

Inflation and Other Risks

The Company is exposed to a variety of market and other risks, including the effects of changes in interest rates and inflation, as well as risks to the availability of funding sources, hazard events, and specific asset risks. The U.S. economy is experiencing broad and rapid inflation. The Company monitors inflation and the effects of changing prices. Inflation increases the cost of goods and services used. If the Company’s costs were to become subject to significant inflationary pressures, the Company may not be able to fully offset these higher costs through price increases or mitigate the impact through alternative solutions.

Note 2— 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

13

Xos, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

Unaudited

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 period 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

14

Xos, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements

Unaudited

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 liabilities 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.

Note 7 — 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

19

Xos, Inc. and Subsidiaries

Unaudited

•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

Unaudited

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.

Note 9 — 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.

Note 10 — 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.

Legal Contingencies

Legal claims may arise from time to time in the normal course of business, the results of which may have a material effect on the Company’s accompanying consolidated financial statements. As of June 30, 2022 and December 31, 2021, the Company was not a party to any legal proceedings, that individually or in the aggregate, are reasonably expected to have a material adverse effect on the Company’s results of operations, financial condition or cash flows.

Note 14 — Related Party Transactions

The Company leases property in North Hollywood, California from Valley Industrial Properties which is owned by the Sunseeker Trust. The Sunseeker Trust is an irrevocable trust with the beneficiary being the mother of the CEO, Dakota Semler. Rent expense during each of the three months ended June 30, 2022 and 2021 totaled $35,000, respectively. Rent expense during each of the six months ended June 30, 2022 and 2021 totaled $70,000, respectively.

The Company has contract manufacturing agreements with Metalsa S.A. de C.V. and Fitzgerald Manufacturing Partners. We utilize Metalsa, a Mexico-based automotive supplier, to provide parts and manufacturing services. Metalsa had an investment in the Company in the form of a convertible note payable which was converted as part of the Series A Financing (see Note 9 above). Similarly, we utilize Fitzgerald Manufacturing Partners to provide parts and manufacturing services; the owner is a stockholder of the Company. We also have lease agreements with Fitzgerald Manufacturing Partners, for which we recorded rent expense of $189,000 and $361,000 during the three and six months ended June 30, 2022. No rent expense was recorded for these lease agreements during the three and six months ended June 30, 2021.

The Company had a partial recourse promissory note in the amount of $364,000 due from the COO, Giordano Sordoni. The note was utilized to exercise options provided to him by the Company. Interest is compounded annually at a rate of 2.38%. The note was issued in the amount of $364,000 on June 24, 2019. The full balance and interest of $15,000 was forgiven by the Company during the first quarter of 2021.

The Company converted 34 notes payable with outstanding carrying value of $18.9 million from related parties into 19,664,000 preferred shares of Legacy Xos Preferred Stock as described above in Note 9 - Equity. These related parties consisted of the CEO, COO, board members, board advisors, and various trusts whose beneficiaries are relatives of the CEO.

The Company utilized employees from an entity owned by the CEO in conducting repairs and maintenance at their headquarters. Amounts charged for these services were at the employees’ current salary rates including benefits and totaled $0 and $37,000 during the three months ended June 30, 2022 and 2021, respectively. Amounts charged totaled $0 and $74,000 during the six months ended June 30, 2022 and 2021, respectively.

Note 15 — 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.

Note 17 — 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):

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

XOS’ MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis provides information which Xos’ management believes is relevant to an assessment and understanding of our consolidated results of operations and financial condition. The discussion should be read together with the unaudited condensed consolidated financial statements and related notes that are included in this Report. You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited interim condensed consolidated financial statements and the related notes included elsewhere in this Report and our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 30, 2022. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under the section entitled “Risk Factors”. Unless the context otherwise requires, references in this “Xos Management’s Discussion and Analysis of Financial Condition and Results of Operations” to “we”, “us”, “our”, and “the Company” are intended to mean the business and operations of Xos and its consolidated subsidiaries.

Overview

We are a leading technology company which provides fleet services, software solutions, and manufactures 100% battery-electric Class 5 to Class 8 commercial vehicles. We facilitate the transition of fleets from internal combustion engine vehicles to zero-emission vehicles with proprietary technology suited to the commercial use case. We also provide a range of services to facilitate the transition of fleets to electric vehicles, including charging infrastructure, vehicle maintenance, financing and service.

Our X-Platform (our proprietary, purpose-built vehicle chassis platform) and X-Pack (our proprietary battery system) provide modular features that allow us to accommodate a wide range of last-mile applications and enable us to offer clients at a lower total cost of ownership compared to traditional diesel fleets. The X-Platform and X-Pack are available for purchase as part of the Xos vehicle. The X-Platform and X-Pack were both engineered to be modular in nature to allow fleet operators to customize their vehicles to fit their commercial applications (e.g., upfitting with a specific vehicle body and/or tailoring battery range). In addition to a competitive vehicle purchase price, our technology can also drive savings throughout ownership through increased vehicle uptime, greater payload capacity and reduced service and maintenance expense. Ninety percent of vehicles in our targeted segments operate on routes under 200 miles per shift (referred to as “last-mile” routes). Vehicles that fulfill these predictable last-mile routes generally return to base hubs on a daily basis. Such vehicles are ideal candidates for electrification as operators are able to connect the vehicles to dedicated charging infrastructure at return-to-base hubs. Our modular and cost-effective vehicles have been on the road and in customers’ hands since 2018, further validating the durability of satisfaction with our vehicles. During the six months ended June 30, 2022, we sold 127 vehicles and 2 powertrains. During the six months ended June 30, 2021, we sold 3 vehicles and 6 powertrains.

We have taken a conservative approach to capital investment with our Flex Manufacturing Strategy, which leverages our strategic partners’ existing facilities and labor to assemble up to 5,000 vehicles annually per facility once fully ramped up. This strategy will enable us to scale our operations in a capital efficient manner and in lockstep with market demand. We have partnered with two third-party contract manufacturer partners to operate two Flex facilities. Our Flex facilities are currently tooled to produce up to approximately 2,000 vehicles per annum in total, assuming we are able to mitigate current supply chain constraints.

Our Fleet-as-a-Service product facilitates the transition from traditional internal combustion engine vehicles to battery electric vehicles and provides fleet operators with a comprehensive set of solutions and products (including, but not limited to, Energy Services, service and maintenance, vehicle telematics, OTA updates and financing) to transition to and to operate an electric fleet. This product offering will combine traditionally disaggregated services into a bundled service package, thus reducing the cost and friction associated with electrifying commercial fleets. Services to be offered in our Fleet-as-a-Service offerings include our proprietary technologies and in-house services and offerings from our industry partners. Our Fleet-as-a-Service offering includes (i) Energy Services (on-site vehicle charging infrastructure as well as our proprietary mobile charging unit Xos HubTM); (ii) service and maintenance (provided by our internal maintenance team and industry partners); (iii) replacement parts; (iv) financing via our external partners; (v) risk mitigation products (e.g., GAP insurance and warranties); and (vi) our telematics unit, the Xosphere Intelligence Platform. Fleet-as-a-Service is expected to increase the lifetime revenue of each vehicle sold by us. During the six months ended June 30, 2022, we have generated $16.2 million in revenue (or 97% of revenue) from vehicle sales and Fleet-as-a-Service and $0.6 million from ancillary revenue (or 3% of revenue). During the six months ended June 30, 2021, we generated $1.4 million (or 100% of revenue) from vehicle sales.

35

We believe our growth in the coming years is supported by the strong secular tailwinds of an increased focus on the impact of climate change and the growth of e-commerce and last-mile delivery. Commercial trucks are the largest emitters of greenhouse gases per capita in the transportation industry. The U.S. federal, state and foreign governments, along with corporations such as FedEx, UPS and Amazon, have set ambitious goals to reduce greenhouse gas emissions. Simultaneously, e-commerce continues to grow rapidly and has been accelerated by changes in consumer purchasing behavior during the COVID-19 pandemic. We believe the increased regulation relating to commercial vehicles, the launch of sustainability initiatives from leading financial and corporate institutions and the rapid growth of last-mile logistics will fuel accelerated adoption of our products worldwide.

We expect both our capital and operating expenditures will increase significantly in connection with our ongoing activities, as we:

•continue to invest in research and development and further develop and commercialize our core proprietary technologies, including our X-Platform chassis platform, X-Pack battery system and Fleet-as-a-Service platform;

•increase our investment in marketing and advertising, sales and distribution infrastructure to accelerate the growth in sales of our products and services;

•continue to invest in servicing our growing portfolio of vehicles on the road including account management, maintenance and service technicians and the Xosphere Intelligence Platform;

•continue to build out our supply chain team as well as additional battery and vehicle Flex assembly lines to bolster manufacturing capacity and meet demand targets, and to adjust to macroeconomic changes, including supply chain shortages;

•continue to build out finance operations to maintain and improve financial controls, financial planning and risk management;

•invest in operations functions including IT, administration and human resources to maintain and improve our operational systems, processes and procedures;

•obtain, maintain, expand, and protect our intellectual property portfolio including patents, trade secrets, trademarks and copyrights; and

•further invest in infrastructure to operate in accordance with public company standards and guidelines.

Business Combination

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 transfer by way of continuation and deregistration of NextGen from the Cayman Islands and the continuation and domestication of NextGen as a corporation incorporated in the State of Delaware (the “Domestication”), the “Business Combination”). As a result of the Merger, NextGen completed the Domestication, Merger Sub merged with and into Xos Fleet, Inc. (which was formerly known as Xos, Inc.), the separate corporate existence of Merger Sub ceased and Xos Fleet, Inc. was to be the surviving corporation and a wholly owned subsidiary of NextGen, and NextGen changed its name to “Xos, Inc.” Xos Fleet, Inc. is the accounting predecessor and the combined entity will be the successor SEC registrant, and Xos’ financial statements for previous periods will be disclosed in the registrant’s future periodic reports filed with the SEC.

The Business Combination is accounted for as a reverse recapitalization. Under this method of accounting, NextGen has been treated as the acquired company for financial statement reporting purposes. The most significant change in the successor’s future reported financial position and results is an increase in cash by $216.7 million, net of transaction costs and redemptions. Total non-recurring transaction costs was approximately $55.4 million.

As a consequence of the completion of the Business Combination, we became the successor to an SEC-registered and Nasdaq-listed company with ticker “XOS”, which has required us and will continue to require us to hire additional personnel and implement procedures and processes to address public company regulatory requirements and customary practices. We have incurred and expect to incur additional annual expenses as a public company for, among other things, directors’ and officers’ liability insurance, director fees and additional internal and external accounting and legal and administrative resources, including increased audit and legal fees.

36

Recent Developments

On August 9, 2022, we entered into a securities purchase agreement with YA II PN, Ltd. (“Yorkville”) for the issuance of convertible debentures in the principal amount of up to $35.0 million. Also on August 9, 2022, we entered into a note purchase agreement with Aljomaih Automotive Co. (“Aljomaih”) for the issuance of a convertible promissory note with a principal amount of $20.0 million. For more information related to these agreements, refer to Note 18 - Subsequent Events in the accompanying unaudited condensed consolidated financial statements.

Key Factors Affecting Operating Results

We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including those discussed in this Report.

Successful Commercialization of our Products and Services

We expect to derive future revenue from sales of our vehicles, battery systems and Fleet-as-a-Service offering. As many of these products are in development, we will require substantial additional capital to continue developing our products and services and bring them to full commercialization as well as fund our operations for the foreseeable future. Until we can generate sufficient revenue from product sales, we expect to finance our operations through commercialization and production with proceeds from the Business Combination as well as additional subsequent financing transactions. The amount and timing of our future funding requirements, if any, will depend on many factors, including the pace and results of our commercialization efforts.

Customer Demand

We have sold a limited number of our vehicles to our existing customers, have agreements with future customers and have received interest from other potential customers. We expect that the sales of our vehicles and services to our existing and future customers will be an important indicator of our performance.

Production of Lyra Series, Improved Battery Pack System

We started the production of the Lyra Series of battery packs during the fourth quarter of 2021. The Lyra series of battery packs features a 52% improvement in gravimetric energy density and a 45% improvement in volumetric energy density, and is compatible with all Xos on-highway vehicles. The battery packs come in two configurations: Lyra 30 (29.4kWh) and Lyra 60 (61.8kWh) offering 25 and 50 miles of range, respectively. Each pack features individual, recirculated air cooling and an independent battery management system, offering improved reliability and the ability to mix-and-match packs to cater to each customer’s unique range requirements.

Supply Chain Management

As described more fully below, there are certain areas in our supply chain management that have been disrupted due to global economic conditions and the prolonged effect of the COVID-19 pandemic. Our ability to find alternative solutions to meet customer demands will affect our financial performance.

Global economic conditions, which the COVID-19 pandemic has contributed to, has impacted our ability to source certain of our critical inventory items. The series of restrictions imposed and the speed and nature of the recovery in response to the pandemic has placed a burden on our supply chain management, including but not limited to the following areas:

•Semiconductor chip shortage: The global silicon semiconductor industry has experienced a shortage in supply and difficulties in its ability to meet customer demand. This shortage has led to an increase in lead-times of production of semiconductor chips and components since the beginning of 2020.

•Battery cells: The battery cell industry is facing a shortage in supply which is causing suppliers to limit customer allocations.

•Supply limitation on vehicle bodies and aluminum: Vehicle body suppliers are currently experiencing elevated pricing or a shortage of key materials such as aluminum.

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 to our business, operating results, cash flows, liquidity and financial condition.

37

Despite supply chain disruptions, we have continued to source inventory for our vehicles and our purchasing team has been working with vendors to find alternative solutions to areas where there are supply chain constraints. Where appropriate and critical, we have placed orders in advance of projected need to try and offset disruptions. While we are working to minimize the impact of these supply limitations, we cannot be certain that all inventory will be able to be delivered in time for production plans.

Tightness in supply availability could lead to previously unforeseen cost and delivery pressures on certain material and logistical costs in 2022. As the Company accelerates execution of its strategic plans, we will endeavor to be strategic in our cost action plans, including working with various vendors and service providers to provide us cost-effective arrangements.

Impact of COVID-19

As the COVID-19 pandemic continues to evolve, the ultimate extent of the impact on our businesses, operating results, cash flows, liquidity and financial condition will be primarily driven by the severity and duration of the pandemic as well as the pandemic’s impact on the U.S. and global economies. During the six months ended June 30, 2022, despite the continued COVID-19 pandemic, we continued to operate our business at full capacity, including all of our manufacturing and research and development operations, with the adoption of enhanced health and safety practices. Although we have made our best estimates based upon current information, actual results could materially differ from the estimates and assumptions developed by management. Accordingly, it is reasonably possible that the estimates made in the financial statements have been, or will be, impacted in the near term as a result of these conditions.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of Xos and its wholly owned subsidiaries, Legacy Xos and Xos Services. All significant intercompany accounts and transactions have been eliminated in consolidation. All long-lived assets are maintained in, and all losses are attributable to, the United States.

Currently, we conduct business through one operating segment. We are an early-stage growth company with minimal commercial operations and our activities to date have been conducted primarily within North America. For more information about our basis of operations, refer to Note 1 - Description of Business in the accompanying unaudited condensed consolidated financial statements.

Components of Results of Operations

Revenues

To date, we have primarily generated revenues from the sale of electric stepvan and stripped chassis vehicles and battery systems and the licensing of our software systems. Our stripped chassis is our vehicle offering that comprises our X-Platform electric vehicle base and X-Pack battery systems, which customers can upfit with their preferred vehicle body. As we continue to expand our commercialization, we expect our revenue to come from these products and other vehicle offerings including chassis cabs, which will feature our chassis and powertrain with the inclusion of a proprietary designed cab, and tractors, a shortened version of the chassis cab designed to haul trailers (also known as “day cabs”), that travel in last-mile use cases. In addition, we will offer a full suite of service offerings including Energy Services, service and maintenance, telematics and financing.

Revenue consists of product sales, inclusive of shipping and handling charges, net of estimates for customer allowances. Revenue is measured as the amount of consideration we expect to receive in exchange for delivering products. All revenue is recognized when we satisfy the performance obligations under the contract. We recognize revenue by delivering the promised products to the customer, with the revenue recognized at the point in time the customer takes control of the products. For shipping and handling charges, revenue is recognized at the time the products are delivered to or picked up by the customer. The majority of our current contracts have a single performance obligation, which is met at the point in time that the product is delivered, and title passes, to the customer, and are short term in nature.

38

Cost of Goods Sold

Cost of goods sold includes materials and other direct costs related to production of our vehicles, including components and parts, batteries, direct labor costs and manufacturing overhead, among others. Materials include inventory purchased from suppliers, as well as assembly components that are assembled by company personnel, including allocation of stock-based compensation expense. Direct labor costs relate to the wages of those individuals responsible for the assembly of vehicles delivered to customers. Cost of goods sold also includes depreciation expense on property and equipment related to cost of goods sold activities, calculated over the estimated useful life of the property and equipment on a straight-line basis. Upon property and equipment retirement or disposal, the cost of the asset disposed, and the related accumulated depreciation from the accounts and any gain or loss is reflected in the consolidated statements of operations and comprehensive income (loss), allocated to cost of goods sold.

Cost of goods sold also includes reserves to write down the carrying value of our inventory to their net realizable value and to provide for obsolete and on-hand inventory in excess of forecasted demand.

We are continuing to undertake efforts to find more cost-effective vendors and sources of parts to lower our overall cost of production. Direct labor and overhead costs relate primarily to expenses incurred through our third-party manufacturing partners. We expect these expenses to increase in future periods as production volume increases to meet expected growth in customer demand.

General and Administrative Expenses

General and administrative (“G&A”) expenses consist of personnel-related expenses, outside professional services, including legal, audit and accounting services, as well as expenses for facilities, non-sales related travel, and general office supplies and expenses. Personnel-related expenses consist of salaries, benefits, allocations of stock-based compensation, and associated payroll taxes. Overhead items including rent, insurance, utilities, and other items are included as G&A expenses. G&A expenses also include depreciation expense on property and equipment related to G&A activities, calculated over the estimated useful life of the property and equipment on a straight-line basis. Upon property and equipment retirement or disposal, the cost of the asset disposed, and the related accumulated depreciation from the accounts and any gain or loss is reflected in the consolidated statements of operations and comprehensive income (loss), allocated to G&A.

We expect our G&A to increase for the foreseeable future as we scale headcount with the growth of our business, and as a result of operating as a public company, including compliance with the rules and regulations of the SEC, legal, audit, additional insurance expenses, investor relations activities, and other administrative and professional services.

Research and Development Expenses

Research and development (“R&D”) expenses consist primarily of costs incurred for the design and development of our vehicles and battery systems, which include:

•Expenses related to materials and supplies consumed in the development and modifications to existing vehicle designs, new vehicle designs contemplated for additional customer offerings, and our battery pack design;

•Fees paid to third parties such as consultants and contractors for engineering and computer-aided design (“CAD”) work on vehicle designs and other third-party services; and,

•Payroll expense for employees primarily engaged in R&D activities, including allocation of stock-based compensation expense.

We expect our research and development costs to increase materially for the foreseeable future as we continue to invest in research and development of our battery systems, chassis design and certain other technologies. As such, we expect salaries, benefits, and expenses related to those employees whose primary function is in the design and development of new and redesigned vehicle and battery design (primarily in our engineering department) to increase and be allocated.

Sales and Marketing Expenses

Sales and marketing expenses consist primarily of expenses related to our marketing of vehicles and brand initiatives, which includes:

39

•Travel expenses of our sales force who are primarily responsible for introducing our platform and offerings to potential customers.

•Web design, marketing and promotional items, and consultants who assist in the marketing of the Company.

•Payroll expense for employees primarily engaged in sales and marketing activities, including allocation of stock-based compensation expense.

•Depreciation expense on property and equipment related to sales and marketing activities, calculated over the estimated useful life of the property and equipment on a straight-line basis. Upon property and equipment retirement or disposal, the cost of the asset disposed, and the related accumulated depreciation from the accounts and any gain or loss is reflected in the consolidated statements of operations and comprehensive income (loss), allocated to sales and marketing.

We expect these expenses to increase for the foreseeable future as travel expands due to the planned expansion of our sales team and increasing deployment of both direct and indirect marketing efforts. We expect an increase in our cost of sales and marketing expenses as we expand our ongoing hybrid distribution strategy that utilizes both direct distribution and indirect distribution through partnerships with our dealer network.

Other Income (Expense), Net

Other income (expense), net primarily includes interest income from our investments in marketable debt securities, available-for-sale and interest paid on our equipment leases.

(1) Percentage changes greater than or equal to 400% are not meaningful and noted as “nm” in the table above.

Revenues

Our total revenues increased by $9.2 million, from $0.6 million in the three months ended June 30, 2021 to $9.8 million in the three months ended June 30, 2022 primarily driven by an increase in unit sales. During the three months ended June 30, 2022, we sold 71 stepvans and 2 powertrains, compared to 5 powertrains during the three months ended June 30, 2021.

Our total revenues increased by $15.4 million, from $1.4 million in the six months ended June 30, 2021 to $16.8 million in the six months ended June 30, 2022 primarily driven by increase in unit sales. During the six months ended June 30, 2022, we sold 127 stepvans and 2 powertrains, compared to 3 stepvans and 6 powertrain during the six months ended June 30, 2021.

Cost of Goods Sold

Cost of goods sold increased by $14.3 million, from $0.6 million in the three months ended June 30, 2021 to $14.9 million in the three months ended June 30, 2022. The increase in cost of goods sold is directly attributable to the increase in our product revenues and increases of (i) $1.0 million in the inventory reserve with no such comparable reserve during the three months ended June 30, 2021 and (ii) $13.3 million in direct materials, direct labor, and manufacturing overhead.

Cost of goods sold increased by $23.8 million, from $1.3 million in the six months ended June 30, 2021 to $25.1 million in the six months ended June 30, 2022. The increase in cost of goods sold is directly attributable to the increase in our product revenues and increases of (i) $2.2 million in the inventory reserve with no such comparable reserve during the six months ended June 30, 2021 and (ii) $21.6 million in direct materials, direct labor, and manufacturing overhead.

The increase in direct labor encompasses both employee and subcontractor labor costs. The direct labor costs are primarily attributable to an increased headcount and the temporary labor used to manufacture and fulfill current and future orders. Additionally, the use of our contract manufacturing partners to assist in our chassis production line has increased direct labor costs. The increase in direct material costs, is due to limited supplier contract agreements necessary to get competitive pricing for raw materials. As production increases and we order materials in larger quantities, we expect to have supply contract agreements that decrease the costs of raw materials. A significant portion of the overhead costs incurred include indirect salaries, facility rent, utilities, and depreciation of production equipment, which are primarily fixed in nature and allocated based on production levels. Accordingly, these costs are still incurred when we experience a reduction in production volume. In

41

the near term, we plan to increase production activities, expecting fixed and semi-fixed overhead costs to be absorbed through the production of our batteries and chassis.

General and Administrative

General and administrative expenses increased by $7.5 million, or 163%, from $4.6 million in the three months ended June 30, 2021 to $12.1 million in the three months ended June 30, 2022, attributable to increases of (i) $3.8 million in headcount and personnel cost for supply chain, sales, legal, accounting, information technology and general and administrative functions necessary to support our business growth, (ii) $2.0 million in insurance costs driven by overall coverage increase and the amortization expense of Directors & Officers (“D&O”) insurance, (iii) $0.5 million in consulting and professional service expenses related to the implementation of our new ERP system and financial processes, (iv) $0.3 million in investment for equipment and technology driven by an increase in our headcount and (v) $1.1 million in other operating expenses, including, travel, recruiting, freight and sales tax. These increases were offset by a $0.2 million decrease in depreciation expense due to the allocation of overhead costs to cost of goods sold.

General and administrative expenses increased by $16.5 million, or 237%, from $7.0 million in the six months ended June 30, 2021 to $23.4 million in the six months ended June 30, 2022, attributable to increases of (i) $8.7 million in headcount and personnel cost for supply chain, sales, legal, accounting, information technology and general and administrative functions necessary to support our business growth, (ii) $3.9 million in insurance costs driven by overall coverage increase and the amortization expense of D&O insurance, (iii) $1.7 million in consulting and professional services expenses related to the implementation of our new ERP system and financial processes, (iv) $0.6 million in investment for equipment and technology driven by an increase in our headcount and (v) $1.7 million in other operating expenses, including depreciation, travel, recruiting, freight and sales tax. These increases were offset by a $0.1 million decrease in depreciation expense due to the allocation of overhead costs to cost of goods sold.

Research and Development

Research and development expenses increased by $4.9 million, or 178%, from $2.7 million in the three months ended June 30, 2021 to $7.6 million in the three months ended June 30, 2022. The growth was primarily due to increases of (i) $2.4 million in allocation of personnel costs driven by higher headcount in engineering, including the allocation of stock-based compensation expense, and (iii) $2.5 million in net other costs, driven by equipment and material purchases used solely for R&D purposes.

Research and development expenses increased by $8.8 million, or 154%, from $5.7 million in the six months ended June 30, 2021 to $14.6 million in the six months ended June 30, 2022. The growth was primarily due to increases of (i) $4.9 million in allocation of personnel costs driven by higher headcount in engineering, including the allocation of stock-based compensation expense, and (iii) $3.9 million in net other costs, driven by equipment and material purchases used solely for R&D purposes.

Sales and Marketing

Sales and marketing expense increased by $2.4 million, from $0.5 million in the three months ended June 30, 2021 to $3.0 million in the three months ended June 30, 2022. The growth was primarily due to increases of (i) $1.4 million in allocation of personnel costs driven by higher headcount, including the allocation of stock-based compensation expense and (ii) $1.0 million related to consulting fees, public relations costs, participation in tradeshows and general marketing efforts to enhance brand recognition.

Sales and marketing expense increased by $4.2 million, from $0.8 million in the six months ended June 30, 2021 to $5.0 million in the six months ended June 30, 2022. The growth was primarily due to increases of (i) $3.0 million in allocation of personnel costs driven by higher headcount, including the allocation of stock-based compensation expense and (ii) $1.2 million related to consulting fees, public relations costs, participation in tradeshows and general marketing efforts to enhance brand recognition.

Other Income (Expense), net

Other income (expense), net increased by $0.4 million, or 279%, from $0.1 million of income in the three months ended June 30, 2021 to $(0.2) million of expense in the three months ended June 30, 2022.

Other income (expense), net increased by an immaterial amount from the six months ended June 30, 2021 as compared to the six months ended June 30, 2022.

42

Change in Fair Value of Derivatives

The gain on the change in fair value of derivative instruments increased by $5.1 million, or 359%, from $(1.4) million in the three months ended June 30, 2021 to $3.7 million in the three months ended June 30, 2022. This represents changes in the fair value of the derivatives, including the common stock warrant liability assumed as part of the Business Combination and the conversion feature on the convertible notes issued in prior years.

The gain on change in fair value of derivative instruments decreased by $1.7 million, or 34%, from $5.0 million in the six months ended June 30, 2021 to $3.3 million in the six months ended June 30, 2022. This represents changes in the fair value of the derivatives, including the common stock warrant liability assumed as part of the Business Combination and the conversion feature on the convertible notes issued in prior years and released in the prior year.

Change in Fair Value of Contingent Earn-out Interests Liability

The gain on the change in fair value of contingent earn-out interests liability was $14.9 million and $17.5 million for the three and six months ended June 30, 2022, respectively. The contingent earn-out interest liability was established as part of the Business Combination and therefore, no balances were recorded for the three and six months ended June 30, 2021. The change in fair value for the three and six months ended June 30, 2022 is mainly attributable to the change in our stock price and the resulting valuation at the respective reporting period.

Write-off of Subscription Receivable

In 2020, the Company had a promissory note receivable in the amount of $364,000 due from the Company’s COO, Giordano Sordoni. The note was utilized to exercise options granted to him by the Company. The principal balance of the note and the associated accrued interest was subsequently forgiven during the six months ended June 30, 2021. No similar transaction occurred during the six months ended June 30, 2022.

Realized Loss on Debt Extinguishment

This represents the loss on the conversion of convertible debt into preferred shares during the six months ended June 30, 2021. No similar transaction occurred during the six months ended June 30, 2022.

Provision for income taxes

The Company recorded income tax provision of $1,000 and $0 during the during the three months ended June 30, 2022 and 2021, respectively. The Company recorded income tax provision of $3,000 and $0 during the during the six months ended June 30, 2022 and 2021, respectively.

Liquidity and Capital Resources

We consummated the Business Combination, which resulted in net cash proceeds of approximately $216.7 million. As of June 30, 2022, our principal sources of liquidity were our cash and cash equivalents (excluding restricted cash) and investments in marketable debt securities, available-for-sale aggregating $82.1 million. In December 2020, we had the initial closing of our Series A Financing, and in the first quarter of 2021, we completed the Series A Financing, including the conversion of all our convertible notes into shares of Legacy Xos preferred stock. Prior to our Series A Financing in December 2020 and the Business Combination, we had financed our operations primarily from the sales of convertible notes.

As an early stage growth company, the net losses and cash outflows we have incurred since inception are consistent with our strategy and budget. We will continue to incur net losses and cash outflows in accordance with our operating plan as we continue to expand our research and development activities with respect to our vehicles and battery systems, scale our operations to meet anticipated demand and establish our Fleet-as-a-Service product offering. Our ability to access capital when needed is not assured and, if capital is not available to us when and in the amounts needed, we could be required to delay, scale back or abandon some or all of our development programs and other operations, which could materially harm our business, prospects, financial condition and operating results.

We believe that our existing cash resources, including capital raised in the Series A Financing and Business Combination, are sufficient to support planned operations for the next 12 months. Additionally, on March 23, 2022, the Company entered into a Standby Equity Purchase Agreement (the "SEPA") with Yorkville, whereby the Company shall have the right, but not the obligation, to sell to Yorkville up to $125.0 million of its shares of common stock at the Company's request during the 36 months following the execution of the SEPA, subject to certain conditions. As of June 30, 2022, remaining commitment of

43

$120.7 million was available under the SEPA, provided that, pursuant to the issuance of convertible debentures to Yorkville described below, the Company shall not effect any advance under the SEPA without the prior mutual consent of Yorkville and the Company until the earliest of the date (i) all such convertible debentures have been repaid or converted into common stock or (ii) Yorkville no longer has any right or ability to convert any portion of the convertible debentures into common stock. In connection with the foregoing, the term set forth in the SEPA will be extended for a corresponding number of days. The Company has used the net proceeds received from sales of common stock pursuant to the SEPA to date for working capital and general corporate purposes and expects similar use of proceeds going forward. Further, on August 9, 2022, the Company entered into an agreement with Yorkville for the issuance of convertible debentures in the principal amount of up to $35.0 million, subject to certain conditions, with a maturity date of November 11, 2023. Also on August 9, 2022, we entered into a note purchase agreement with Aljomaih for the issuance of convertible notes with a principal amount of $20.0 million (with an option for Aljomaih to purchase additional convertible notes, on terms and conditions to be negotiated in good faith, in a principal amount of up to an additional $20.0 million) and a maturity date of August 11, 2025, subject to certain conditions.

As a result, our management believes that our current financial resources are sufficient to continue operating activities for at least 12 months past the issuance date of the financial statements. For more information related to these agreements, refer to Note 18 - Subsequent Events in the accompanying unaudited condensed consolidated financial statements.

Cash Flows Summary

Net increase (decrease) in cash and cash equivalents	$	(11,891)	$	13,258

Cash Flows from Operating Activities

Our cash flows from operating activities are significantly affected by the growth of our business primarily related to research and development and selling, general, and administrative activities and working capital needs to support growth in inventory reserves and fluctuations in accounts payable and other current assets and liabilities.

Net cash used in operating activities was $75.8 million for the six months ended June 30, 2022, primarily consisting of a net loss excluding non-cash expenses and gains of $44.1 million, and net changes in operating assets and liabilities of $31.7 million, including $33.1 million in inventory cost build-up as production ramps up.

Net cash used in operating activities was $20.2 million for the six months ended June 30, 2021, primarily consisting of a net loss excluding non-cash expenses and gains of $13.1 million, and net changes in operating assets and liabilities of $7.0 million, including $4.9 million in inventory cost build-up in anticipation of production ramp-up.

Cash Flows from Investing Activities

Cash flows from investing activities primarily relate to the sales and maturities of marketable securities, offset by capital expenditures to support our growth. Net cash used in capital expenditures is expected to continue to expand.

Net cash provided by investing activities was $60.1 million for the six months ended June 30, 2022, due to net proceeds from sale of investments in marketable debt securities of $69.6 million, offset by property and equipment additions of $9.5 million.

Net cash used in investing activities was $0.7 million for the six months ended June 30, 2021, due to property and equipment additions.

Cash Flows from Financing Activities

Net cash provided by financing activities was $3.8 million for the six months ended June 30, 2022, primarily related to proceeds from the issuance of common stock under the SEPA of $4.3 million, offset by taxes paid relating to net-settlement of stock-based awards of $0.2 million and equipment lease principal payments of $0.3 million.

44

Net cash provided by financing activities was $34.1 million for the six months ended June 30, 2021, which primarily related to the Series A Financing in December 2020, resulting in the receipt of $34.1 million in cash and subscription receivables. As part of this financing, we also converted all of our convertible debt and accrued interest to additional shares of Legacy Xos Preferred Stock in January 2021.

Contractual Obligations and Commitments

We did not have any material contractual obligations or other commitments as of June 30, 2022, other than what’s disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined under the applicable rules and regulations of the SEC.

Critical Accounting Policies and Estimates

Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) which 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. Our most significant estimates and judgments involve 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. We base our 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 our financial statements.

There were no material changes in our critical accounting policies, as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.

Recent Accounting Pronouncements

See Note 2 — Basis of Presentation and Summary of Significant Accounting Policies to our unaudited condensed consolidated financial statements included in this filing for more information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one, of their potential impact on our financial condition and our results of operations.

Internal Control Over Financial Reporting

As disclosed in our 2021 Form 10-K, we were not required to comply with the rules of the SEC implementing Section 404 of the Sarbanes-Oxley Act, based on our business combination date and are therefore not required to make a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. We excluded management’s report on internal controls over financial reporting pursuant to Section 215.02 of the SEC’s Compliance and Disclosure Interpretations. We are required to disclose changes made in our internal controls and procedures on a quarterly basis, we are not required to make our first annual assessment of our internal control over financial reporting pursuant to Section 404 until the year following our first annual report required to be filed with the SEC post-merger, which is December 31, 2022. We have begun the process of establishing a system of internal control to support management’s evaluation of internal control subsequent to the completed Business Combination on August 20, 2021.

Effective internal controls are necessary to provide reliable financial reports and to assist in the effective prevention of fraud. Any inability to provide reliable financial reports or prevent fraud could harm our business. Any system of internal controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. As part of our process to establish an effective system of internal controls, management has identified areas of improvement in our preliminary system of internal control over financial reporting that we are working diligently to address.

If we cannot conclude that we have effective internal control over our financial reporting, investors could lose confidence in the reliability of our financial statements, which could lead to a decline in our stock price. Failure to comply with reporting requirements could also subject us to sanctions and/or investigations by the SEC, the NASDAQ or other regulatory authorities. If we fail to remedy any deficiencies or maintain the adequacy of our internal controls, we could be subject to regulatory

45

scrutiny, civil or criminal penalties or stockholder litigation. In addition, failure to maintain adequate internal controls could result in financial statements that do not accurately reflect our operating results or financial condition.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to a variety of market and other risks, including the effects of changes in interest rates, inflation, and foreign currency exchange rates, as well as risks to the availability of funding sources, hazard events, and specific asset risks.

Interest Rate Risk

The market risk inherent in our financial instruments and our financial position represents the potential loss arising from adverse changes in interest rates. We maintain a portfolio of investments in a variety of fixed and variable debt rate securities, including, U.S. treasuries, corporate debt, asset-backed securities, non-U.S. government and supranational bonds and certificate of deposit. As of June 30, 2022, the fair value of investments in marketable debt securities, available-for-sale was $77.9 million. The primary objective of our investment activity is to maintain the safety of principal, and to provide for future liquidity requirements while maximizing yields without significantly increasing risk. While some investments may be securities of companies in foreign countries, all investments are denominated and payable in U.S. Dollars. We do not enter into investments for trading or speculative purposes. While our intent is not to sell these investment securities prior to their stated maturities, we may choose to sell any of the securities for strategic reasons including, but not limited to, anticipated capital requirements, anticipation of credit deterioration, duration management and because a security no longer meets the criteria of our investment policy. We do not use derivatives or similar instruments to manage our interest rate risk. We seek to invest in high quality investments. The weighted average rating (exclusive of cash and cash equivalents) was A as of June 30, 2022. Maturities are maintained consistent with our short-, medium- and long-term liquidity objectives.

The following table sets forth the impact on the fair value of our investments as of June 30, 2022 from changes in interest rates based on the weighted average duration of the debt securities in our portfolio (dollars in thousands):

	Approximate Change in Fair Value of Investments
Change in Interest Rate	Increase (Decrease)
2% Decrease	$	945
1% Decrease	$	472
1% Increase	$	(467)
2% Increase	$	(931)

Foreign Currency Risk

There was no material foreign currency risk for the three and six months ended June 30, 2022 and 2021.

Inflation Risk

We monitor inflation and the effects of changing prices. Inflation increases the cost of goods and services used. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset these higher costs through price increases or mitigate the impact through alternative solutions. Our inability to do so could harm our business, financial condition and results of operations.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in company reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

46

As required by Rules 13(a)-15(e) and 15(d)-15(e) under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out evaluations of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2022. Based upon each of their evaluations, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Rules 13(a)-15(e) and 15(d)-15(e) under the Exchange Act) were effective as of the end of the quarter ended June 30, 2022.

Changes in Internal Control over Financial Reporting

During the quarter ended June 30, 2022, we continue to be engaged in the process of design and implementation of our internal control over financial reporting in a manner commensurate with the scale of our operations subsequent to the business combination, including the enhancement of our internal and external technical accounting resources.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

47

Part II - Other Information

Item1.    Legal Proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not currently a party to any legal proceedings, the outcome of which, if determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, financial condition or results of operations.

Item 1A.    Risk Factors

Our risk factors are described in the “Risk Factors” section of our 2021 Form 10-K. There have been no material changes to our risk factors since the filing of the 2021 Form 10-K.

Item 2.     Unregistered Sales of Equity Securities and Use of Proceeds

On March 23, 2022, we entered into the SEPA with Yorkville, whereby we shall have the right, but not the obligation, to sell to Yorkville up to $125.0 million of shares of our Common Stock at our request during the 36 months following the execution of the SEPA, subject to certain conditions.

In consideration for Yorkville’s commitments under the SEPA, we issued 18,582 shares of our Common Stock to Yorkville on March 23, 2022. We did not receive any cash proceeds in connection with this issuance.

During the three months ended June 30, 2022, we received cash proceeds of $4.3 million in connection with the issuance of 1,809,515 shares of common stock under the SEPA. We expect to use any net proceeds for working capital and general corporate purposes.

The issuance of the securities in this transaction was made in reliance on the exemption from registration in Section 4(a)(2) under the Securities Act.

EX-10.1

XOS, INC.

THIRD AMENDED AND RESTATED

NON-EMPLOYEE DIRECTOR COMPENSATION POLICY

Adopted by the Board of Directors: August 8, 2022

Each member of the Board of Directors (the “Board”) of Xos, Inc. (the “Company”) who is not also serving as an employee of the Company or any of its subsidiaries (each such member, a “Non-Employee Director”) and who is not otherwise precluded from participation in this Non-Employee Director Compensation Policy (this “Policy”) as the Board or its designee may decide in its discretion, will be eligible to receive the compensation described in this Non-Employee Director Compensation Policy (this “Policy”) for his or her Board service. Unless otherwise defined herein, capitalized terms used in this Policy will have the meaning given to such terms in the Company’s 2021 Equity Incentive Plan, as may be amended and/or restated from time to time, or any successor equity incentive plan (the “Plan”).

This Policy will be effective as of the date it is adopted by the Board

1. Annual Cash Compensation

Commencing on October 1, 2021, each Non-Employee Director will receive the cash compensation as set forth below for service on the Board. Each Non-Employee Director will be entitled to receive the following annual cash retainers for service on the Board:

Annual Lead Director Service Retainer: $25,000

Annual Committee Chair Service Retainer:

Chairperson of the Audit Committee: $20,000

Chairperson of the Compensation Committee: $10,000

Chairperson of the Nominating and Corporate Governance Committee: $10,000

The annual cash retainers above will be payable in equal quarterly installments in arrears on the last day of each fiscal quarter (each such date, a “Retainer Accrual Date”) in which the service occurred, prorated for any partial quarter of service (based on the number of days served in the applicable position divided by the total number of days in the quarter). All annual cash retainers will be vested upon payment. The Company may establish a program pursuant to which Non-Employee Directors may elect to receive their retainers in shares of Common Stock rather than in cash.

2. Equity Compensation

Each Non-Employee Director will be entitled to receive the equity compensation set forth below (as applicable), subject to the terms and conditions hereof. All such equity compensation will be granted under the Plan.

(a) Annual Grant. Without any further action by the Board or Compensation Committee, on the first date following each Annual Meeting of the Company’s stockholders where the Board and/or Compensation Committee is approving equity awards per their then-current regular equity award grant schedule, which at the time of effectiveness of this policy is on the 10th day of each calendar month (or if the 10th is not a business day, the first business day thereafter), each person who is then a continuing Non-

Employee Director will automatically be granted that number of restricted stock units with a value of $200,000 in the aggregate (each, an “Annual Grant”). The number of restricted stock units will be determined by dividing the relevant dollar value by the average Fair Market Value (as defined in the Plan) of the underlying Common Stock for the thirty (30) calendar day period ending five calendar days before the date of the applicable Annual Meeting (or, if such date is not a business day, the first business day thereafter) rounded down to the nearest whole share. Each Annual Grant will vest on the earlier of (i) the first anniversary of the applicable grant date and (ii) the day before the next Annual Meeting following the applicable grant date, subject to the Non-Employee Director’s Continuous Service through the vesting date.

(b) Vesting; Change in Control. All vesting is subject to the Non-Employee Director’s Continuous Service on each applicable vesting date.Notwithstanding the foregoing, for each Non-Employee Director who remains in Continuous Service as of, or immediately prior to, a Change in Control, the shares subject to his or her then-outstanding equity awards that were granted pursuant to this Policy will become fully vested immediately prior to such Change in Control.

(c) Remaining Terms. The remaining terms and conditions of each equity award granted pursuant to this Policy will be as set forth in the Plan and the Company’s applicable award grant notice and award agreement, in the form adopted from time to time by the Board or Compensation Committee of the Board.

3. Non-Employee Director Compensation Limit

Notwithstanding anything herein to the contrary, the cash compensation and equity compensation that each Non-Employee Director is entitled to receive under this Policy shall be subject to the limits set forth in the Plan.

4. Ability to Decline or Defer Compensation

A Non-Employee Director may decline all or any portion of his or her compensation under this Policy by giving notice to the Company prior to the date such cash is earned or such equity awards are to be granted, as the case may be. A Non-Employee Director may elect to defer receipt of payment of his or her cash compensation and/or settlement of any equity award granted pursuant to the Policy in accordance with a deferral election program administered by the Company in compliance with the provisions of Section 409A.

5. Expenses

The Company will reimburse each Non-Employee Director for ordinary, necessary and reasonable out-of-pocket travel expenses to cover in-person attendance at and participation in Board and committee meetings; provided, that the Non-Employee Director timely submits to the Company appropriate documentation substantiating such expenses in accordance with the Company’s travel and expense policy, as in effect from time to time.

6. Amendment

This Policy may be amended at any time in the sole discretion of the Board or the Compensation Committee of the Board.

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.

Inflation and Other Risks

The Company is exposed to a variety of market and other risks, including the effects of changes in interest rates and inflation, as well as risks to the availability of funding sources, hazard events, and specific asset risks. The U.S. economy is experiencing broad and rapid inflation. The Company monitors inflation and the effects of changing prices. Inflation increases the cost of goods and services used. If the Company’s costs were to become subject to significant inflationary pressures, the Company may not be able to fully offset these higher costs through price increases or mitigate the impact through alternative solutions.

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 period 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 liabilities 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.

Operating Leases

The Company has a 5-year office lease on its headquarter facility in Los Angeles, which commenced in January 2022, as well as certain other leases (both short-term and long-term) within the United States.

The Company records lease expense on a straight-line basis over the lease term in general and administrative expense and cost of goods sold, depending on the nature and use of the leased asset. Total lease expense for the three months ended June 30, 2022 and 2021 was $0.4 million and $0.1 million, respectively. Total lease expense recorded was $0.9 million and $0.3 million, for the six months ended June 30, 2022 and 2021,respectively.

Lease terms include renewal or termination options that the Company is reasonably certain to exercise. For leases with a term of 12 months or less, the Company has made an accounting policy election to not record a ROU asset and associated lease liability on its unaudited condensed consolidated balance sheet. Total lease expense recorded for these short-term leases was $0.3 million and $0.4 million for the three and six months ended June 30, 2022, respectively.

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.

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.

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.

Share-Based Compensation

2018 Stock Plan

On November 27, 2018, the Legacy Xos’ board of directors and stockholders adopted the 2018 Stock Plan. There are no shares available for issuance under the 2018 Stock Plan; however, the 2018 Stock Plan continues to govern the terms and conditions of the outstanding awards granted under the 2018 Stock Plan.

Options

As of June 30, 2022, there were 1,786,679 Options outstanding under the 2018 Stock Plan. The amount and terms of Option grants were determined by the board of directors of Legacy Xos. The Options granted under the 2018 Stock Plan generally expire within 10 years from the date of grant and generally vest over 4 years, at the rate of 25% on the first anniversary of the date of grant and ratably on a monthly basis over the remaining 36-month period thereafter based on continued service.

Stock option activity during the six months ended June 30, 2022 consisted of the following:

	Options	Weighted Average Fair Value		Weighted Average Exercise Price		Weighted Average Remaining Years	Intrinsic Value

The aggregate intrinsic value of options exercised during the three months ended June 30, 2022 and 2021 were approximately $114,000 and $0, respectively. The aggregate intrinsic value of options exercised during the six months ended June 30, 2022 and 2021 were approximately $115,000 and $6,000, respectively.

The Company estimates the fair value of options utilizing the Black-Scholes option pricing model, which is dependent upon several variables, including expected option term, expected volatility of the Company's share price over the expected term, expected risk-free rate and expected dividend yield rate. There were no option grants during the three and six months ended June 30, 2022 and 2021.

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 MeasurementsASC 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):

Convertible Debentures

On August 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.

Basis of Presentation and Summary of Significant Accounting Policies - (Policies)

Jun. 30, 2022

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 period 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 liabilities 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.
