Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Embark Technology, Inc. (“Embark” or the “Company”) was originally incorporated in Delaware on September 25, 2020 under the name Northern Genesis Acquisition Corp. II (“NGA”). The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. On November 10, 2021 (the “Closing Date”), the Company (at such time named Northern Genesis Acquisition Corp. II) consummated the business combination (the “Business Combination”) pursuant to the Agreement and Plan of Merger, dated June 22, 2021 with the pre-Business Combination company, Embark Trucks, Inc. (“Embark Trucks”). In connection with the consummation of the Business Combination, the Company changed its name from Northern Genesis Acquisition Corp. II to Embark Technology, Inc. and became the parent entity of Embark Trucks. The Merger was accounted for as a reverse recapitalization with Embark as the accounting acquirer and NGA as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the condensed consolidated financial statements represent the accounts of Embark as if Embark is the predecessor to the Company. The shares and net loss per common share, prior to the Merger, have been retroactively restated as shares reflecting the exchange ratio established in the Merger (approximately 2.98 shares of Company Class A common stock for 1 share of Embark Class A common stock). The principal activities of Embark Technology, Inc. include design and development of autonomous driving software for the truck freight industry. The Company is headquartered in San Francisco, California and was incorporated in the State of Delaware in 2016. Other than Embark Trucks, the Company has no other subsidiaries as of September 30, 2022. The Company has devoted substantially all of its resources to develop its autonomous truck technology, to enable and expand its route models - transfer point and direct-to-customer, to expand its partnerships with shippers and carriers and other potential consumers, to raising capital, and providing general and administrative support for these operations. The Company has not generated revenues from its principal operations from inception through September 30, 2022. Prior to the Merger, NGA ordinary shares and warrants were traded on the New York Stock Exchange under the ticker symbols “NGAB” and “NGAB.WS”, respectively. On the Closing Date, the Company’s Class A common stock and warrants began trading on the NASDAQ under the ticker symbols “EMBK” and “EMBKW”, respectively. One of the primary purposes of the Merger was to provide a platform for Embark Trucks to gain access to the U.S. capital markets. Basis of Presentation The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the regulations of the SEC. The condensed consolidated financial statements include the accounts of the Company’s wholly-owned subsidiary. All intercompany transactions and balances have been eliminated upon consolidation. Unaudited Interim Financial Information These interim Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited financial statements and notes thereto contained in Embark’s Annual Report. The condensed consolidated balance sheet at December 31, 2021, has been derived from the audited financial statements at that date, but does not include all disclosures, including notes, required by GAAP for complete financial statements. In management’s opinion, the unaudited interim financial statements have been prepared on the same basis as the annual financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of September 30, 2022 and the Company’s results of operations for the three and nine months ended September 30, 2022 and 2021, and cash flows for the nine months ended September 30, 2022 and 2021. The interim results are not necessarily indicative of the results for any future interim period or for the entire year. Business Combination The Company entered into the Merger Agreement with NGA, a special purpose acquisition company, on June 22, 2021. On November 10, 2021, as part of the Business Combination, NGAB Merger Sub Inc., a newly formed subsidiary of NGA (“Merger Sub”), merged with and into Embark Trucks. In connection with the consummation of the Business Combination, the separate corporate existence of Merger Sub ceased; Embark Trucks survived and became a wholly owned subsidiary of NGA, which was renamed Embark Technology, Inc. The Business Combination was accounted for as a reverse recapitalization, in accordance with GAAP. Under the guidance in ASC 805, Embark was treated as the “acquirer” company for the accounting purposes. Embark Trucks was deemed the accounting predecessor of the combined business, and Embark Technology, Inc., as the parent company of the combined business, was the successor SEC registrant, meaning that Embark’s financial statements for previous periods will be disclosed in the registrant’s periodic reports filed with the SEC. The Business Combination had a significant impact on Embark’s reported financial position and results as a consequence of the reverse recapitalization. The most significant change in Embark’s reported financial position and results was a net increase in cash of $243.9 million, net of transaction costs for the Business Combination of $70.2 million. Reverse Stock Split On August 15, 2022, the directors of the Company approved an amendment to the Company’s second amended and restated certificate of incorporation (the “Certificate of Incorporation”) to effect a reverse stock split (the “Reverse Stock Split”) of the Company’s outstanding common stock, par value $0.0001 per share (the “Common Stock”), at the ratio of 1-for-20. Following the close of trading on the Nasdaq Global Market on August 16, 2022 (the “Effective Time”), the Company filed a certificate of amendment to the Certificate of Incorporation (the “Amendment”) with the Secretary of State of the State of Delaware to effect the Reverse Stock Split. All references in these financial statements to number of common shares issued or outstanding, price per share, outstanding equity awards as well as the applicable exercise price, and weighted average number of shares outstanding prior to the 1 for 20 reverse split have been adjusted to reflect the stock split on a retroactive basis as of the earliest period presented, unless otherwise noted. Warrants will be impacted by the same ratio upon exercise. No fractional shares were issued in connection with the Reverse Stock Split. The Reverse Stock Split did not affect the number of authorized shares of Embark’s common stock, the par value of the common stock, the number of warrants issued and outstanding, or the exercise price of the warrants. Liquidity and Capital Resources The Company has incurred losses from operations since inception. The Company incurred net losses of $68.2 million and $47.8 million for the nine months ended September 30, 2022 and 2021, respectively, and accumulated deficit amounts of $251.1 million and $182.9 million as of September 30, 2022 and December 31, 2021, respectively. Net cash used in operating activities was $66.3 million and $32.9 million for the nine months ended September 30, 2022 and 2021, respectively. The Company’s liquidity is based on its ability to enhance its operating cash flow position, obtain capital financing from equity interest investors, and borrow funds to fund its general operations, research and development activities and capital expenditures. As of September 30, 2022 and December 31, 2021, the Company’s balance of cash and cash equivalents was $191.0 million and $264.6 million, respectively. Based on cash flow projections from operating and financing activities and existing balance of cash and cash equivalents and investments, management is of the opinion that the Company has sufficient funds for sustainable operations, and it will be able to meet its payment obligations from operations and debt related commitments for at least one year from the issuance date of these financial statements. Based on the above considerations, the Company’s financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities during the normal course of operations. The Company’s ability to continue as a going concern is dependent on management’s ability to control operating costs and demonstrate progress against its technical roadmap. This involves developing new capabilities for the Embark Driver software and improving the reliability and performance of the software on public roads. The Company believes demonstrating ongoing technical and commercial progress will enable the Company to obtain funds from outside sources of financing, including financing from equity interest investors and borrow funds to fund its general operations, research and development activities and capital expenditures. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes- Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the 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 Securities Act registration statement declared effective or do not have a class of securities registered under 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. This may make comparison of the Company’s financial statements with another public company that is either a) not an emerging growth company or b) an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Segment Information Under Accounting Standards Codification (“ASC 280”), Segment Reporting , operating segments are defined as components of an enterprise where discrete financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”), in deciding how to allocate resources and in assessing performance. The Company operates in one segment, the truck business unit, which is focused on enhancing self-driving truck software technology. Therefore, the Company’s chief executive officer, who is also the CODM, makes decisions and manages the Company’s operations as a single operating segment for purposes of allocating resources and evaluating financial performance. All long-lived assets are maintained in, and all losses are attributable to, the United States of America. Concentration of Risks Embark’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and restricted cash. Embark maintains its cash and cash equivalents and restricted cash with high-quality financial institutions with investment-grade ratings. A majority of the cash balances are with U.S. banks and are insured to the extent defined by the Federal Deposit Insurance Corporation. Impact of COVID-19 The outbreak of the novel coronavirus COVID-19, which was declared a global pandemic by the World Health Organization on March 11, 2020 has led to adverse impacts on the U.S. and global economies and has impacted and continues to impact the Company’s supply chain, and operations. Even though the Company has taken measures to adapt to operating in this challenging environment, the pandemic could further affect the Company’s operations and the operations of, partners, suppliers and vendors due to additional shelter- in-place and other governmental orders, facility closures, travel and logistics restrictions, or other factors as circumstances continue to evolve. In response to this pandemic, many jurisdictions in which the Company operates issued stay-at-home orders and other measures aimed at slowing the spread of the virus. While the Company remains open in accordance with guidance from local authorities, the Company experienced a temporary pause in testing of its research and development truck fleet and operations in response to the stay- at-home orders in calendar year 2021. The impacts from stay-at-home orders and other updated local government indoor operation measures associated with COVID-19 and its variants are not currently impacting the Company’s operations, however, there remains continuing uncertainty around the potential disruptions the pandemic could cause looking forward. The Company has instituted policies across its offices to ensure compliance with the guidelines imposed by the applicable public health

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions 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 expenses during the reporting period. The Company’s most significant estimates and judgments involve the useful lives of long-lived assets, the recoverability of long-lived assets, the incremental borrowing rate (“IBR”) applied in lease accounting, the capitalization of software development costs, the valuation of the Company’s stock-based compensation, including the valuation of warrants to purchase the Company’s stock and the valuation allowance for income taxes. 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. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. As of September 30, 2022 and December 31, 2021, the Company had $191.0 million and $264.6 million of cash and cash equivalents, respectively. The Company maintains letters of credit to secure leases of the Company’s offices and facilities. A portion of the Company’s cash is collateralized in conjunction with the letter of credit and is classified as restricted cash on the Company’s condensed consolidated balance sheets. As of September 30, 2022 and December 31, 2021, the Company had $0.9 million and $0.4 million in restricted cash, respectively. At the end of each year of the lease, the face amount of the letter of credit is reduced by a fixed amount of approximately $0.1 million and reclassified into cash and cash equivalents on the Company’s condensed consolidated balance sheets. The Company determines short-term or long-term classification based on the expected duration of the restriction. The reconciliation of cash and cash equivalents and restricted cash and cash equivalents to amounts presented in the condensed consolidated statements of cash flows are as follows (in thousands): As of September 30, As of December 31, 2022 2021 2021 Cash and cash equivalents $ 191,040 $ 47,886 $ 264,615 Restricted cash, short-term 65 65 130 Restricted cash, long-term 812 340 275 Total cash, cash equivalents and restricted cash $ 191,917 $ 48,291 $ 265,020 Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, restricted cash, prepaid expenses and other current assets, accounts payable and accrued expenses, short-term and long-term notes payable and other current liabilities. The assets and liabilities that were measured at fair value on a recurring basis are cash equivalents and warrant liabilities. The Company believes that the carrying values of the remaining financial instruments approximate their fair values. The Company applies fair value accounting in accordance with ASC 820, Fair Value Measurements for valuation of financial instruments . ASC 820 provides a framework for measuring fair value under GAAP that expands disclosures about fair value measurements, establishes a fair value hierarchy, and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the fair value hierarchy are summarized as follows: Level 1 — Fair value is based on observable inputs such as quoted prices for identical assets or liabilities in active markets. Level 2 — Fair value is determined using quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active or are directly or indirectly observable. Level 3 — Fair value is determined using one or more significant inputs that are unobservable in active markets at the measurement date, such as an option pricing model, discounted cash flow, or similar technique. Public and Private Warrants As part of NGA’s initial public offering on October 13, 2020, NGA issued to third party investors 41.4 million units, consisting of one share of Class A common stock of NGA and one-third of one warrant, at a price of $10.00 per unit. Each whole warrant entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per share (the “Public Warrants”). Further, NGA completed the private sale of 6.7 million warrants to NGA's sponsor at a purchase price of $1.50 per warrant (the “Private Placement Warrants” or “Private Warrants”). Following the reverse stock split, each warrant allows the holder to purchase 1/20th of one share of Class A common stock at $11.50 per share. Subsequent to the Business Combination, 13.8 million Public Warrants and 6.7 million Private Warrants remained outstanding as of September 30, 2022. Following the Reverse Stock Split effectiveness on August 16, 2022, warrants will be impacted by the same ratio upon exercise. The Reverse Stock Split did not affect the number of warrants issued and outstanding or the exercise price of the warrants. Each whole warrant exercisable is now for 1/20th share of Class A common stock at an exercise price of $11.50 per share. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A common stock issuable upon the exercise of the Private Placement Warrants did not become transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants are exercisable on a cashless basis and are 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 purchasers or their permitted transferees, the Private Placement Warrants are redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company evaluated the Public and Private Warrants under ASC 815-40, Derivatives and Hedging-Contracts in Entity's Own Equity , and concluded that they do not meet the criteria to be classified in stockholders' equity. Since the Public and Private Warrants meet the definition of a derivative under ASC 815, the Company recorded these warrants as liabilities on the balance sheet at fair value upon the closing of the Business Combination, with subsequent changes in their respective fair values recognized in the condensed consolidated statements of operations and comprehensive income (loss) at each reporting date. Property, Equipment and Software Property, equipment and software is stated at cost less accumulated depreciation. Repair and maintenance costs are expensed as incurred. Depreciation and amortization are recorded on a straight-line basis over each asset’s estimated useful life. Property, Equipment and Software Useful life (years) Machinery and equipment 5 years Electronic equipment 3 years Vehicles and vehicle hardware 3 – 7 years Leasehold improvements Shorter of useful life or lease term Furniture and fixtures 7 years Developed software 2 – 4 years Leases The Company determines if a contract contains a lease at inception of the arrangement based on whether the Company has the right to obtain substantially all of the economic benefits from the use of an identified asset and whether the Company has the right to direct the use of an identified asset in exchange for consideration, which relates to an asset which the Company does not own. 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. ROU assets are recognized as the lease liability, adjusted for lease incentives received. Lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s IBR, because the interest rate implicit in most of its leases is not readily determinable. The IBR is a hypothetical rate based on the Company’s understanding of what its credit rating would be to borrow and resulting interest we would pay to borrow an amount equal to the lease payments in a similar economic environment over the lease term on a collateralized basis. Lease payments may be fixed or variable; however, only fixed payments or in-substance fixed payments are included in the Company’s lease liability calculation. Variable lease payments may include costs such as common area maintenance, utilities, real estate taxes or other costs. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. Operating leases are included in operating lease ROU assets, operating lease liabilities, current and operating lease liabilities, non-current on the Company’s condensed consolidated balance sheets. For operating leases, lease expense is recognized on a straight-line basis in operations over the lease term. The Company elected the practical expedient not to separate non-lease components from lease components, therefore, the Company accounts for lease and non-lease components as a single lease component. The Company also elected the short-term lease recognition practical expedient for all leases that qualify. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment annually, or whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. The Company assesses the recoverability of these assets by comparing the carrying amount of such assets or asset group to the future undiscounted cash flows it expects the assets or asset group to generate. The Company recognizes an impairment loss if the sum of the expected long-term undiscounted cash flows that the long-lived asset is expected to generate is less than the carrying amount of the long-lived asset being evaluated. Income Taxes The Company accounts for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s lack of earnings history, the net deferred tax assets have been fully offset by a valuation allowance as of September 30, 2022 and December 31, 2021. Uncertain tax positions taken or expected to be taken in a tax return are accounted for using the more likely than not threshold for financial statement recognition and measurement. Stock-based Compensation Stock-based compensation expense related to stock option awards, restricted stock units (“RSUs”) and performance stock units (“PSUs”) granted to employees, directors and non-employees are accounted for based on estimated grant-date fair values. For stock option awards and RSUs with service conditions, the Company uses the straight-line method to recognize compensation expense over the requisite service period, which is generally the vesting period, and estimates the fair value of share-based awards using the Black-Scholes option- pricing model. The Black-Scholes model requires the input of subjective assumptions, including expected volatility, expected dividend yield, expected term, risk-free rate of return and the stock price of the underlying common shares on the date of grant. The fair value of each RSU is based on the fair value of the Company’s common stock on the date of grant. Stock-based compensation for RSUs granted with a performance condition is recognized on a graded vesting basis. Stock-based compensation tor PSUs, is recognized on a graded vesting basis, as the PSUs are associated with market conditions over the holder’s derived service period. The fair value of the PSUs are estimated using the Monte Carlo simulation. The Company accounts for the effect of forfeitures as they occur. Internal Use Software The Company capitalizes certain costs associated with creating and enhancing internally developed software for the Company’s technology infrastructure and such costs are recorded within property, equipment and software, net. These costs include personnel and related employee benefit expenses for employees directly associated with and who devote time to software development projects. Software development costs that do not qualify for capitalization are expensed as incurred and recorded in research and development expense in the condensed consolidated statements of operations. Software development activities typically consist of three stages: (1) the planning phase; (2) the application and infrastructure development stage; and (3) the post implementation stage. Costs incurred in the planning and post implementation phases, including costs associated with training and repairs and maintenance of the developed technologies, are expensed as incurred. The Company capitalizes costs associated with software developed when the preliminary project stage is completed, management implicitly or explicitly authorizes and commits to funding the project and it is probable that the project will be completed and perform as intended. Costs incurred in the application and infrastructure development phases, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete, and the software is ready for its intended purpose. Software development costs are depreciated using the straight-line method over the estimated useful life, commencing when the software is ready for its intended use. The straight-line recognition method approximates the manner in which the expected benefit will be derived. Internal use software is tested for impairment in accordance with the Company’s long- lived assets impairment policy. Research and Development Expense Research and development expense consist of outsourced engineering services, allocated facilities costs, depreciation, internal engineering and development expenses, materials, labor, and stock-based compensation related to development of the Company’s products and services. Research and development costs are expensed as incurred except for amounts capitalized to internal-use software. General, and Administrative Expenses General, and administrative expense consist of personnel costs, allocated facilities expenses, depreciation and amortization, travel, and business development costs. Change in fair value of warrant liability Change in fair value of warrant liability represents the change in fair value of Public, Private, Working Capital and Forward Purchase Agreement (“FPA”) Warrants. For each reporting period, Embark will determine the fair value of the warrant liability, and record a corresponding non-cash benefit or non-cash charge, due to a decrease or increase in fair value, respectively, of the calculated warrant liability. Other Income As part of the Company’s research and development activities, we contract with shippers and freight carriers to transfer freight between the Company’s transfer hubs in return for cash consideration. Transferring freight with the Company’s research and development truck fleet are not and will not be considered an output of the Company’s anticipated ordinary revenue-generating activities. Consideration received from such arrangements is presented as other income in the Company’s condensed consolidated statement of operations. Interest Income Interest income primarily consists of investment and interest income from marketable securities, long- term investments and the Company’s cash and cash equivalents. Interest Expense Interest expense consisted primarily of interest on the Company’s various truck financing arrangements. Net Loss Per Share Prior to the Merger and prior to effecting the recapitalization, the Company had one class of common stock. Subsequent to the Merger, the Company has two classes of common stock: Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock are identical, including the liquidation and dividend rights, except with respect to electing members of the Board of Directors and voting rights. As the liquidation and dividend rights are identical, undistributed earnings and losses are allocated on a proportionate basis and the resulting net loss per share attributable to common stockholders are the same for both Class A common stock and Class B common stock on an individual and combined basis. Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Net loss is attributed to common stockholders and participating securities based on their participation rights. Net loss attributable to common stockholders is not allocated to the redeemable convertible preferred stock as the holders of the redeemable convertible preferred stock do not have a contractual obligation to share in any losses. No dividends were declared or paid for the three or nine months ended September 30, 2022. No preferred stock was outstanding as of September 30, 2022. Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share attributable to common stockholders adjusts basic earnings per share for the potentially dilutive impact of redeemable convertible preferred stock, stock options, and warrants. As the Company has reported losses for all periods presented, all potentially dilutive securities including preferred stock, stock options, and warrants, are antidilutive and accordingly, basic net loss per share equals diluted net loss per share. Comprehensive Loss Comprehensive loss is defined as the total change in stockholders’ equity during the period other than from transactions with stockholders. Comprehensive loss consists of net loss and other comprehensive loss. Other comprehensive loss is comprised of unrealized losses on investments classified as available-for-sale and losses on foreign currency revaluations. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The Company adopted “ASC 842” on January 1, 2022, using the modified retrospective transition method, specifically the "Comparatives under ASC 840 approach", and used the effective date as the date of initial application. The Company elected the “package of practical expedients,” which permits Embark not to reassess under ASC 842 its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the use of hindsight in determining the lease term and in assessing impairment of the entity’s right-of-use assets. Upon adoption of the new leasing standard on January 1, 2022, the Company recognized right-of-use assets of $4.4 million and lease liabilities of $4.5 million, respectively, which are related to its various operating leases. The difference between the right-of-use assets and lease liabilities is primarily attributed to the elimination of deferred rent. There was no adjustment to the opening balance of accumulated deficit as a result of the adoption of ASC 842. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which is intended to simplify various aspects related to accounting for income taxes. The adoption of ASU 2019-12 is effective for the Company beginning January 1, 2022. The adoption of this standard did not have a material impact to its financial statements. In May 2021, the FASB issued ASU 2021-04, Modification of equity-classified written call options . ASU 2021-04 provides clarification and reduces diversity in an issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options, such as warrants, that remain equity classified after modification or exchange. The adoption of ASU 2021-04 was effective for the Company beginning January 1, 2022. The adoption of this standard did not have a material impact to its financial statements. Recently Issued Accounting Pronouncements As an emerging growth company (“EGC”), the JOBS Act allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act until such time the Company is no longer considered to be an EGC. The adoption dates discussed below reflect this election. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments , which, together with subsequent amendments, amends the requirement on the measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for the Company beginning January 1, 2023, with early adoption permitted. The Company is currently in the process of evaluating the effects of this pronouncement on the Company’s financial statements and does not expect it to have a material impact on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815- 40): Accounting for convertible instruments and contracts in an entity’s own equity. The ASU simplifies accounting for convertible instruments by removing certain separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it revises the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share for convertible instruments by using the if-converted method. The amendments are effective for the Company beginning January 1, 2024, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the impact of this standard on its consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” This standard requires an acquirer to apply Accounting Standards Codification Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this standard on its consolidated financial statements. In June 2022, the FASB issued ASU 2022-03 to clarify the guidance on the fair value measurement of an equity security that is subject to a contractual sale restriction, and require specific disclosures for equity securities that are subject to such restrictions. The amendments are effective in periods beginning after December 15, 2023 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this standard on its consolidated financial statements. In September 2022, the FASB issued ASU 2022-04, "Liabilities - Supplier Finance Programs (Subtopic 405-50)." ASU 2022-04 is intended to establish disclosures that enhance the transparency of a supplier finance program used by an entity in connection with the purchase of goods and services. Supplier finance programs, which also may be referred to as

Equity [Abstract]
STOCKHOLDERS’ EQUITY	STOCKHOLDERS’ EQUITY The Reverse Stock Split The Reverse Stock Split did not affect the number of authorized shares of Embark’s common stock or the par value of the common stock. Following the Reverse Stock Split effectiveness on August 16, 2022, all references in these financial statements to number of common shares issued or outstanding, price per share and weighted average number of shares outstanding prior to the 1 for 20 reverse split have been adjusted to reflect the stock split on a retroactive basis as of the earliest period presented, unless otherwise noted. Shares Authorized and Issued As of September 30, 2022, the Company had authorized a total of 4,110,000,000 shares for issuance with 4,000,000,000 shares designated as Class A common stock, 100,000,000 shares designated as Class B common stock and 10,000,000 shares designated as preferred stock. As of September 30, 2022, the Company had 18,848,766 shares issued as Class A common stock and 4,353,948 shares issued as Class B common stock. Preferred Stock As of September 30, 2022, the Company had no shares of preferred and founders preferred stock issued or outstanding. The Company’s preferred stock, as of September 30, 2022, does not contain any mandatory redemption features, nor are they redeemable at the option of the holder. Class A and Class B Common Stock The Company’s Board of Directors has authorized two class of common stock, Class A common stock and Class B common stock. Holders of Class A common stock and Class B common stock are not entitled to preemptive or other similar subscription rights to purchase any of Embark’s securities. Class A common stock is neither convertible nor redeemable. Class B common stock is convertible into Class A common stock. Unless Embark’s board of directors determines otherwise, Embark will issue all of its capital stock in certificated form. Embark’s founders, Alex Rodrigues and Brandon Moak (the “Founders”), held, and continue to hold, all outstanding shares of Class B common stock upon consummation of the Business Combination. In connection with the merger with NGA on November 10, 2021, the Embark Founders exchanged 4,353,948 shares of Founder’s common stock, which were entitled to one vote per share, into the same number of shares of Class B common stock, which are entitled to ten votes per share. The Company recorded the incremental value of $13.6 million associated with this transaction as stock-based compensation in general and administrative expenses. The significant rights, privileges and preferences of common stock as of September 30, 2022 are as follows: Liquidation Preference If Embark is involved in voluntary or involuntary liquidation, dissolution or winding up of Embark’s affairs, or a similar event, each holder of Embark Common Stock will participate pro rata in all assets remaining after payment of liabilities, subject to prior distribution rights of Embark preferred stock, if any, then outstanding. Dividends Each holder of shares of Embark Common Stock is entitled to the payment of dividends and other distributions as may be declared by the Board from time to time out of Embark’s assets or funds legally available for dividends or other distributions. These rights are subject to the preferential rights of the holders of Embark’s Preferred Stock, if any, and any contractual limitations on Embark’s ability to declare and pay dividends. Voting Each holder of Class A common stock is entitled to one vote per share on each matter submitted to a vote of stockholders, as provided by the Second Amended and Restated Certificate of Incorporation of Northern Genesis Acquisition Corp. II (the “Charter”). Each holder of Class B common stock is entitled to ten votes per share on each matter submitted to a vote of stockholders, as provided by the Embark Charter. Following the Business Combination, holders of Class B common stock have the ability to control the business affairs of Embark. Embark’s Amended and Restated Bylaws (the “Bylaws”) provide that the holders of a majority of the capital stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, will constitute a quorum at all meetings of the stockholders for the transaction of business. When a quorum is present, the affirmative vote of a majority of the votes cast is required to take action, unless otherwise specified by law, the Bylaws or the Charter, and except for the election of directors, which is determined by a plurality vote. There are no cumulative voting rights. Stock purchase agreement On May 31, 2022, the Company entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) and a Registration Rights Agreement, each with CF Principal Investments LLC (“Cantor”). Pursuant to the Purchase Agreement, the Company has the right to sell to Cantor up to the lesser of (i) 1,500,000 of newly issued shares of the Company’s Class A common stock, par value $0.0001 per share, and (ii) the Exchange Cap (as defined in the Purchase Agreement), from time to time during the 36-month term of the Purchase Agreement. Sales of Class A common stock pursuant to the Purchase Agreement, and the timing of any sales, are solely at the option of the Company, and the Company is under no obligation to sell any securities to Cantor under the Purchase Agreement. The total number of shares to be sold to Cantor is limited to the extent that shares sold to Cantor would not result in Cantor and its affiliates having shares in excess of the Beneficial Ownership Limitation. The purchase price of shares sold to Cantor will be equal to 97% of the volume weighted average price on the trading day the shares are put to Cantor. The Company determined that the right to sell shares of the Company’s Class A common stock to Cantor pursuant to the Purchase Agreement represents a freestanding put option under ASC 815, Derivatives and Hedging. The fair value of the put option was determined to be zero as the shares to be issued and the purchase price is settled within one business day. During the three months ended September 30, 2022, the Company did not sell shares of Class A common stock to Cantor pursuant to the Purchase Agreement. As consideration for Cantor’s commitment to purchase shares of Class A common stock at the Company’s direction upon the terms and subject to the conditions set forth in the Purchase Agreement, the Company agreed to issue 22,500 shares of Class A common stock (the “Commitment Shares”) to Cantor at the time of execution of the Purchase Agreement. On May 31, 2022, the Company issued the Commitment Shares to Cantor with a fair value of $0.7 million. The fair value associated with the Commitment Shares was recorded as a component of other expense in the Company’s condensed consolidated statement of operations and a component of common stock and additional paid-in capital in the company’s condensed consolidated balance sheet.

The fair value of the FPA and Public warrants are remeasured as of the reporting date with the change in value reflected as part of other income (expense). The fair value of $1.6 million of Private and Working Capital warrants was determined using the Black-Scholes option valuation model using the following assumptions for values as of September 30, 2022: Risk – free interest rate 4.14% Expected term (in years) 4.11 Expected dividend yield 0% Expected volatility 105.0% The Company estimates the volatility of its warrants based on a combination of volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

Share-Based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION EXPENSE	STOCK-BASED COMPENSATION EXPENSE Stock Option Plan In connection with the Business Combination, the Company adopted the 2021 Incentive Award Plan (the “2021 Plan”), under which the Company grants cash and equity incentive awards to directors, employees (including named executive officers) and consultants in order to attract, motivate and retain the talent for which the Company competes. The Company terminated the 2016 Stock Plan, provided that the outstanding awards previously granted under the 2016 Plan continue to remain outstanding under the 2016 Plan. Under the 2021 Plan, as of September 30, 2022, the Company has authorized the issuance of a maximum number of 3,843,688 shares of Class A common stock, with annual increases that began on January 1, 2022 and ending on and including January 1, 2031 of 5% of the aggregate number of shares of Class A common stock outstanding on the last day of the preceding calendar year. As of September 30, 2022, the Company issued 1,169,670 shares of restricted stock units under the 2021 Plan. Embark Trucks adopted the 2016 Stock Plan in October 2016 (the “2016 Plan”). The 2016 Plan authorized the grant of incentive stock options, non-statutory stock options, and restricted stock awards to employees, directors, and consultants. The 2016 Plan also initially reserve d 993,542 sh ares of common stock (8,941,878 shares post-split in June 2018) for issuance and designated forfeited option sha res to be returned to the option reserve. Options may be early exercised and are exercisable for a term of 10 years from the date of grant. As of September 30, 2022, the Company had registered 3,937,824 shares to be reserved for option grants, RSUs and PSUs previously issued under the 2016 Plan. The Company will not issue additional awards under the 2016 Plan. Stock Option Valuation The Company utilizes the Black-Scholes option pricing model for estimating the fair value of options granted, which requires the input of highly subjective assumptions. The Company calculates the fair value of each option grant on the grant date using the following assumptions: Expected Term — The Company uses the simplified method when calculating expected term due to insufficient historical exercise data. Expected Volatility — As the Company’s shares are not actively traded, the volatility is based on a benchmark of comparable companies within the automotive and energy storage industries. Expected Dividend Yield — The dividend rate used is zero as the Company does not have a history of paying dividends on its common stock and does not anticipate doing so in the foreseeable future. Risk-Free Interest Rate — The interest rates used are based on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term equal to the expected life of the award.

The company did not grant any stock options for the nine months ended September 30, 2022. The weighted average grant date fair value per share for the stock option grants during the nine months ended September 30, 2021 was $37.60. As of September 30, 2022, the total unrecognized compensation related to unvested stock option awards granted was $3.40 million, which the Company expects to recognize over a weighted-average period of approximately 2.1 years. Restricted Stock Units Prior to the Business Combination, Embark Trucks also granted employees RSUs which are subject to performance and service-based vesting conditions. As the Company went public upon the completion of the Business Combination in November 2021, the performance condition had been met. The RSUs generally vest over either a four year period with 25% of the awarded vesting after the first-year anniversary and one-thirty sixth of the remainder of the award vesting monthly thereafter or over a four year period with a 40/30/20/10 monthly schedule. Vesting is contingent upon such employee’s continued service on such vesting date. RSUs are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. The Company may grant RSUs with different vesting terms from time to time. For the three and nine months ended September 30, 2021, the Company granted 423,823 shares of RSUs under the 2016 Equity Plan. The weighted average grant date fair value per share for the RSUs granted for the three and nine months ended September 30, 2021 was $167.22. For the three and nine months ended September 30, 2022, the Company granted 223,810 and 1,169,670 shares of RSUs under the 2021 Equity Plan, respectively. The weighted average grant date fair value per share for the RSUs grants during the three and nine months ended September 30, 2022 was $8.88 and $21.36, respectively. As of September 30, 2022 there was $41.1 million unrecognized stock-based compensation expense related to outstanding RSUs granted to employees, with a weighted-average remaining vesting period of 3.0 years. A summary of the Company’s RSU activities and related information is as follows: Number of Shares Weighted Average Grant date Fair Value Per Share Balance as of December 31, 2021 480,838 $ 168.79 Granted 1,169,670 21.36 Forfeited (165,012) 53.07 Vested (267,260) 106.60 Balance as of September 30, 2022 1,218,236 $ 56.26 Performance Stock Units During 2021, Embark Trucks granted PSUs to its founders. The PSUs are subject to certain market and performance-based conditions which require the Company to become a registered public company and meet market conditions that are based on the Company achieving six different valuation tranches as derived from the achievement of escalating share price thresholds of $400.00, $700.00, $1000.00, $1300.00, $1600.00 and $2000.00 (calculated based on the 90-day volume weighted average price or, in the event of a change in control, the fair market value based on the terms of such change in control) following the first anniversary of the consummation of the Business Combination. The market condition can be achieved over ten years in relation to the pre-money valuation prior to the Business Combination. Once the performance condition has been achieved or is considered probably of being achieved, the related stock-based compensation is recognized based on a graded attribution method. As of September 30, 2022, there was $75.7 million unrecognized stock-based compensation expense related to outstanding PSUs granted to employees, with a weighted-average remaining vesting period of 7.4 years. The Company’s PSUs activity for the nine months ended September 30, was as follows: Number of Shares Weighted Average Grant date Fair Value Per Share Balance as of December 31, 2021 2,235,780 $ 39.37 Granted — — Forfeited — — Vested — — Balance as of September 30, 2022 2,235,780 $ 39.37 Common Stock Units The Company is obligated to issue shares of Class A common stock upon the vesting of certain restricted stock awards that resulted from Embark Trucks warrants that were issued prior to the Business Combination. Pursuant to the terms of these warrant awards, the restricted stock awards were issued for services at the time of consummation of the Business Combination, and are subject to service vesting terms, with the shares being subject to cancellation. The pre-Business Combination warrants were exercised in their entirety on a cashless basis, with the unvested shares being excluded from the stockholders’ equity and becoming subject to the service vesting condition going forward. Early exercises are reclassified to additional paid-in capital as the Company’s cancellation right lapses. The number of unvested shares of Class A common stock were 54,071 as of September 30, 2022. As of September 30, 2022, there was $3.0 million unrecognized stock-based compensation expense related to outstanding Common Stock Units (“CSUs”) granted to non-employees, with a weighted-average remaining vesting period of 1.8 years. The Company's CSUs activity for the nine months ended September 30, 2022 was as follows: Number of Shares Weighted Average Grant date Fair Value Per Share Balance as of December 31, 2021 74,054 $ 49.66 Vested (19,983) 49.66 Balance as of September 30, 2022 54,071 $ 49.66 Overview The following table presents the impact of stock-based compensation expense on the condensed consolidated statements of operations for the three and nine months ended September 30, 2022 and 2021 respectively (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Research and development $ 4,483 $ 315 $ 12,202 $ 966 General, and administrative 6,436 247 27,740 695 Total stock-based compensation expense $ 10,919 $ 562 $ 39,942 $ 1,661 Total stock-based compensation that was capitalized into internally developed software asset was $0.2 million and $0.1 million during the three months ended September 30, 2022 and 2021, respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Proceedings The Company is subject to legal and regulatory actions that arise from time to time in the ordinary course of business. The assessment as to whether a loss is probable or reasonably possible, and as to whether such loss or a range of such loss is estimable, often involves significant judgment about future events. In the opinion of management, all such matters are not expected to have a material effect on the financial position, results of operations or cash flows of the Company. However, the outcome of litigation is inherently uncertain. On April 1, 2022, Tyler Hardy filed, a putative securities class action lawsuit against Embark, certain of our executive officers, and former executive officers of Northern Genesis Acquisition Corp., captioned Hardy v. Embark Technology, Inc., et al ., Case No. 3:22-cv-02090-JSC, in the United States District Court for the Northern District of California (“Hardy Action”). Hardy brought the action purportedly on behalf of a class consisting of those who purchased or otherwise acquired Embark common stock between January 12, 2021 and January 5, 2022. The complaint alleges that defendants made false and/or misleading statements in violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. On July 7, 2022, the Court appointed Tyler Hardy as lead plaintiff in the case, and his counsel at Pomerantz LLP as lead counsel. On August 25, 2022, pursuant to Court-approved stipulation, Plaintiff Hardy filed a consolidated amended complaint, naming an additional plaintiff, Danny Rochefort, and additional individual defendants that formerly served as directors of Northern Genesis Acquisition Corp. prior to its business combination with Embark. The amended complaint alleges that defendants committed violations of Sections 11 and 15 of the Securities Act of 1933 (“Securities Act Claims”) and Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 (“Exchange Act Claims”) through the inclusion of allegedly inaccurate and misleading statements in the Form S-4 registration statement and proxy statement/prospectus filed in connection with the business combination. Plaintiffs do not quantify any damages in the complaint, but in addition to attorneys’ fees and costs, seek to recover damages on behalf of two classes: 1) a class that acquired shares traceable to the registration statement at issue in the Securities Act Claims and 2) a class that voted in favor of the business combination based on the information in the proxy statement/prospectus at issue in the Exchange Act Claims and purportedly suffered financial harm as a result. On October 24, 2022 Embark moved to dismiss the amended complaint pursuant to Rules 9 and 12(b)(6) of the Federal Rules of Civil Procedure as well as under the Private Securities Litigation Reform Act on the grounds that the Amended Complaint fails to plead facts sufficient to state a claim against Defendants. Embark intends to defend the matter vigorously, and believes that the claims are without merit. Legal and regulatory proceedings, including the above-referenced matter, may be based on complex claims involving substantial uncertainties and unascertainable damages. Accordingly, it is not possible to determine the probability of loss or estimate damages for the above-referenced matter, and therefore, Embark has not established reserves for this proceeding. If Embark determines that a loss is both probable and reasonably estimable, Embark will record a liability, and, if the liability is material, will disclose the amount of the liability reserved. Given that such proceedings are subject to uncertainty, there can be no assurance that legal proceedings individually or in the aggregate will not have a material adverse effect on our business, results of operations, financial condition or cash flows. On September 23, 2022, Josh Luberisse filed a purported derivative action against current and former directors and against Embark as a nominal defendant captioned Luberisse v. Ian Robertson et al ., Case No. 3:22-cv-05455 in the United States District Court for the Northern District of California (the “Derivative Action”). The Derivative Action complaint alleges violations of Section 14(a) of the Securities Exchange Act and for alleged common law claims including breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement and for contribution under Section 11(f) of the Securities Act of 1933 and Section 21D of the Securities Exchange Act of 1934 arising from allegedly wrongful conduct including the wrongful conduct alleged in the original and amended complaint in the Hardy Action. In addition to fees and costs, the Derivative Action seeks damages and restitution to Embark from the named individual defendants as well as certain injunctive relief. Embark cannot determine the probability of loss or estimate damages at this stage of the proceeding. Operating leases The Company’s leases primarily include corporate offices. The lease term of operating leases vary from less than a year to seven years. The Company has leases that include one or more options to extend the lease term to a total term of ten years as well as options to terminate the lease within one year. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise such options. The Company’s lease agreements generally do not contain any residual value guarantees or restrictive covenants. On August 1, 2022, the Company moved into its new headquarter office, located at 321 Alabama Street in San Francisco California. The Company classifies this lease as an operating lease with a term of 84 months and contains an option to renew and extend the term for 60 months. The components of lease expense were as follows (in thousands): Three Months Ended September 30, 2022 Nine Months Ended September 30, 2022 Lease cost Operating lease cost $ 1,281 $ 2,491 Short-term lease cost (1) 70 274 Total lease cost $ 1,351 $ 2,765 ___________________ (1) The Company elected to account for short-term leases in accordance with ASC 842. ASC 842 defines a short-term lease as a lease whose lease term, at commencement, is 12 months or less and that does not include a purchase option whose exercise is reasonable certain. The Company will recognize the lease payments in profit or loss on a straight-line basis over the lease term.

	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the regulations of the SEC. The condensed consolidated financial statements include the accounts of the Company’s wholly-owned subsidiary. All intercompany transactions and balances have been eliminated upon consolidation.
Business Combination	Business Combination The Company entered into the Merger Agreement with NGA, a special purpose acquisition company, on June 22, 2021. On November 10, 2021, as part of the Business Combination, NGAB Merger Sub Inc., a newly formed subsidiary of NGA (“Merger Sub”), merged with and into Embark Trucks. In connection with the consummation of the Business Combination, the separate corporate existence of Merger Sub ceased; Embark Trucks survived and became a wholly owned subsidiary of NGA, which was renamed Embark Technology, Inc.
Emerging Growth Company	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes- Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the 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 Securities Act registration statement declared effective or do not have a class of securities registered under 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. This may make comparison of the Company’s financial statements with another public company that is either a) not an emerging growth company or b) an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Segment Information	Segment Information Under Accounting Standards Codification (“ASC 280”), Segment Reporting , operating segments are defined as components of an enterprise where discrete financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”), in deciding how to allocate resources and in assessing performance. The Company operates in one segment, the truck business unit, which is focused on enhancing self-driving truck software technology. Therefore, the Company’s chief executive officer, who is also the CODM, makes decisions and manages the Company’s operations as a single operating segment for purposes of allocating resources and evaluating financial performance. All long-lived assets are maintained in, and all losses are attributable to, the United States of America.
Concentration of Risks	Concentration of Risks Embark’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and restricted cash. Embark maintains its cash and cash equivalents and restricted cash with high-quality financial institutions with investment-grade ratings. A majority of the cash balances are with U.S. banks and are insured to the extent defined by the Federal Deposit Insurance Corporation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions 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 expenses during the reporting period. The Company’s most significant estimates and judgments involve the useful lives of long-lived assets, the recoverability of long-lived assets, the incremental borrowing rate (“IBR”) applied in lease accounting, the capitalization of software development costs, the valuation of the Company’s stock-based compensation, including the valuation of warrants to purchase the Company’s stock and the valuation allowance for income taxes. 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.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted CashThe Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, restricted cash, prepaid expenses and other current assets, accounts payable and accrued expenses, short-term and long-term notes payable and other current liabilities. The assets and liabilities that were measured at fair value on a recurring basis are cash equivalents and warrant liabilities. The Company believes that the carrying values of the remaining financial instruments approximate their fair values. The Company applies fair value accounting in accordance with ASC 820, Fair Value Measurements for valuation of financial instruments . ASC 820 provides a framework for measuring fair value under GAAP that expands disclosures about fair value measurements, establishes a fair value hierarchy, and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the fair value hierarchy are summarized as follows: Level 1 — Fair value is based on observable inputs such as quoted prices for identical assets or liabilities in active markets. Level 2 — Fair value is determined using quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active or are directly or indirectly observable. Level 3 — Fair value is determined using one or more significant inputs that are unobservable in active markets at the measurement date, such as an option pricing model, discounted cash flow, or similar technique.
Public and Private Warrants	The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A common stock issuable upon the exercise of the Private Placement Warrants did not become transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants are exercisable on a cashless basis and are 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 purchasers or their permitted transferees, the Private Placement Warrants are redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company evaluated the Public and Private Warrants under ASC 815-40, Derivatives and Hedging-Contracts in Entity's Own Equity , and concluded that they do not meet the criteria to be classified in stockholders' equity. Since the Public and Private Warrants meet the definition of a derivative under ASC 815, the Company recorded these warrants as liabilities on the balance sheet at fair value upon the closing of the Business Combination, with subsequent changes in their respective fair values recognized in the condensed consolidated statements of operations and comprehensive income (loss) at each reporting date.
Property, Equipment and Software	Property, Equipment and Software Property, equipment and software is stated at cost less accumulated depreciation. Repair and maintenance costs are expensed as incurred. Depreciation and amortization are recorded on a straight-line basis over each asset’s estimated useful life. Property, Equipment and Software Useful life (years) Machinery and equipment 5 years Electronic equipment 3 years Vehicles and vehicle hardware 3 – 7 years Leasehold improvements Shorter of useful life or lease term Furniture and fixtures 7 years Developed software 2 – 4 years
Leases	Leases The Company determines if a contract contains a lease at inception of the arrangement based on whether the Company has the right to obtain substantially all of the economic benefits from the use of an identified asset and whether the Company has the right to direct the use of an identified asset in exchange for consideration, which relates to an asset which the Company does not own. 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. ROU assets are recognized as the lease liability, adjusted for lease incentives received. Lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s IBR, because the interest rate implicit in most of its leases is not readily determinable. The IBR is a hypothetical rate based on the Company’s understanding of what its credit rating would be to borrow and resulting interest we would pay to borrow an amount equal to the lease payments in a similar economic environment over the lease term on a collateralized basis. Lease payments may be fixed or variable; however, only fixed payments or in-substance fixed payments are included in the Company’s lease liability calculation. Variable lease payments may include costs such as common area maintenance, utilities, real estate taxes or other costs. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. Operating leases are included in operating lease ROU assets, operating lease liabilities, current and operating lease liabilities, non-current on the Company’s condensed consolidated balance sheets. For operating leases, lease expense is recognized on a straight-line basis in operations over the lease term. The Company elected the practical expedient not to separate non-lease components from lease components, therefore, the Company accounts for lease and non-lease components as a single lease component. The Company also elected the short-term lease recognition practical expedient for all leases that qualify.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment annually, or whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. The Company assesses the recoverability of these assets by comparing the carrying amount of such assets or asset group to the future undiscounted cash flows it expects the assets or asset group to generate. The Company recognizes an impairment loss if the sum of the expected long-term undiscounted cash flows that the long-lived asset is expected to generate is less than the carrying amount of the long-lived asset being evaluated.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s lack of earnings history, the net deferred tax assets have been fully offset by a valuation allowance as of September 30, 2022 and December 31, 2021. Uncertain tax positions taken or expected to be
Stock-based Compensation	Stock-based Compensation Stock-based compensation expense related to stock option awards, restricted stock units (“RSUs”) and performance stock units (“PSUs”) granted to employees, directors and non-employees are accounted for based on estimated grant-date fair values. For stock option awards and RSUs with service conditions, the Company uses the straight-line method to recognize compensation expense over the requisite service period, which is generally the vesting period, and estimates the fair value of share-based awards using the Black-Scholes option- pricing model. The Black-Scholes model requires the input of subjective assumptions, including expected volatility, expected dividend yield, expected term, risk-free rate of return and the stock price of the underlying common shares on the date of grant. The fair value of each RSU is based on the fair value of the Company’s common stock on the date of grant. Stock-based compensation for RSUs granted with a performance condition is recognized on a graded vesting basis. Stock-based compensation tor PSUs, is recognized on a graded vesting basis, as the PSUs are associated with market conditions over the holder’s derived service period. The fair value of the PSUs are estimated using the Monte Carlo simulation. The Company accounts for the effect of forfeitures as they occur.
Internal Use Software	Internal Use Software The Company capitalizes certain costs associated with creating and enhancing internally developed software for the Company’s technology infrastructure and such costs are recorded within property, equipment and software, net. These costs include personnel and related employee benefit expenses for employees directly associated with and who devote time to software development projects. Software development costs that do not qualify for capitalization are expensed as incurred and recorded in research and development expense in the condensed consolidated statements of operations. Software development activities typically consist of three stages: (1) the planning phase; (2) the application and infrastructure development stage; and (3) the post implementation stage. Costs incurred in the planning and post implementation phases, including costs associated with training and repairs and maintenance of the developed technologies, are expensed as incurred. The Company capitalizes costs associated with software developed when the preliminary project stage is completed, management implicitly or explicitly authorizes and commits to funding the project and it is probable that the project will be completed and perform as intended. Costs incurred in the application and infrastructure development phases, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete, and the software is ready for its intended purpose. Software development costs are depreciated using the straight-line method over the estimated useful life, commencing when the software is ready for its intended use. The straight-line recognition method approximates the manner in which the expected benefit will be derived. Internal use software is tested for impairment in accordance with the Company’s long- lived assets impairment policy.
Research and Development Expense	Research and Development Expense Research and development expense consist of outsourced engineering services, allocated facilities costs, depreciation, internal engineering and development expenses, materials, labor, and stock-based compensation related to development of the Company’s products and services. Research and development costs are expensed as incurred except for amounts capitalized to internal-use software.
General, and Administrative Expenses	General, and Administrative Expenses General, and administrative expense consist of personnel costs, allocated facilities expenses, depreciation and amortization, travel, and business development costs.
Change in fair value of warrant liability	Change in fair value of warrant liability Change in fair value of warrant liability represents the change in fair value of Public, Private, Working Capital and Forward Purchase Agreement (“FPA”) Warrants. For each reporting period, Embark will determine the fair value of the warrant liability, and record a corresponding non-cash benefit or non-cash charge, due to a decrease or increase in fair value, respectively, of the calculated warrant liability.
Other Income	Other Income As part of the Company’s research and development activities, we contract with shippers and freight carriers to transfer freight between the Company’s transfer hubs in return for cash consideration. Transferring freight with the Company’s research and development truck fleet are not and will not be considered an output of the Company’s anticipated ordinary revenue-generating activities. Consideration received from such arrangements is presented as other income in the Company’s condensed consolidated statement of operations.
Interest Income	Interest Income Interest income primarily consists of investment and interest income from marketable securities, long- term investments and the Company’s cash and cash equivalents.
Interest Expense	Interest ExpenseInterest expense consisted primarily of interest on the Company’s various truck financing arrangements.
Net Loss Per Share	Net Loss Per Share Prior to the Merger and prior to effecting the recapitalization, the Company had one class of common stock. Subsequent to the Merger, the Company has two classes of common stock: Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock are identical, including the liquidation and dividend rights, except with respect to electing members of the Board of Directors and voting rights. As the liquidation and dividend rights are identical, undistributed earnings and losses are allocated on a proportionate basis and the resulting net loss per share attributable to common stockholders are the same for both Class A common stock and Class B common stock on an individual and combined basis. Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Net loss is attributed to common stockholders and participating securities based on their participation rights. Net loss attributable to common stockholders is not allocated to the redeemable convertible preferred stock as the holders of the redeemable convertible preferred stock do not have a contractual obligation to share in any losses. No dividends were declared or paid for the three or nine months ended September 30, 2022. No preferred stock was outstanding as of September 30, 2022. Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share attributable to common stockholders adjusts basic earnings per share for the potentially dilutive impact of redeemable convertible preferred stock, stock options, and warrants. As the Company has reported losses for all periods presented, all potentially dilutive securities including preferred stock, stock options, and warrants, are antidilutive and accordingly, basic net loss per share equals diluted net loss per share.
Comprehensive Loss	Comprehensive Loss Comprehensive loss is defined as the total change in stockholders’ equity during the period other than from transactions with stockholders. Comprehensive loss consists of net loss and other comprehensive loss. Other comprehensive loss is comprised of unrealized losses on investments classified as available-for-sale and losses on foreign currency revaluations.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The Company adopted “ASC 842” on January 1, 2022, using the modified retrospective transition method, specifically the "Comparatives under ASC 840 approach", and used the effective date as the date of initial application. The Company elected the “package of practical expedients,” which permits Embark not to reassess under ASC 842 its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the use of hindsight in determining the lease term and in assessing impairment of the entity’s right-of-use assets. Upon adoption of the new leasing standard on January 1, 2022, the Company recognized right-of-use assets of $4.4 million and lease liabilities of $4.5 million, respectively, which are related to its various operating leases. The difference between the right-of-use assets and lease liabilities is primarily attributed to the elimination of deferred rent. There was no adjustment to the opening balance of accumulated deficit as a result of the adoption of ASC 842. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which is intended to simplify various aspects related to accounting for income taxes. The adoption of ASU 2019-12 is effective for the Company beginning January 1, 2022. The adoption of this standard did not have a material impact to its financial statements. In May 2021, the FASB issued ASU 2021-04, Modification of equity-classified written call options . ASU 2021-04 provides clarification and reduces diversity in an issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options, such as warrants, that remain equity classified after modification or exchange. The adoption of ASU 2021-04 was effective for the Company beginning January 1, 2022. The adoption of this standard did not have a material impact to its financial statements. Recently Issued Accounting Pronouncements As an emerging growth company (“EGC”), the JOBS Act allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act until such time the Company is no longer considered to be an EGC. The adoption dates discussed below reflect this election. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments , which, together with subsequent amendments, amends the requirement on the measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for the Company beginning January 1, 2023, with early adoption permitted. The Company is currently in the process of evaluating the effects of this pronouncement on the Company’s financial statements and does not expect it to have a material impact on its consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815- 40): Accounting for convertible instruments and contracts in an entity’s own equity. The ASU simplifies accounting for convertible instruments by removing certain separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it revises the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share for convertible instruments by using the if-converted method. The amendments are effective for the Company beginning January 1, 2024, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently assessing the impact of this standard on its consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” This standard requires an acquirer to apply Accounting Standards Codification Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this standard on its consolidated financial statements. In June 2022, the FASB issued ASU 2022-03 to clarify the guidance on the fair value measurement of an equity security that is subject to a contractual sale restriction, and require specific disclosures for equity securities that are subject to such restrictions. The amendments are effective in periods beginning after December 15, 2023 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this standard on its consolidated financial statements. In September 2022, the FASB issued ASU 2022-04, "Liabilities - Supplier Finance Programs (Subtopic 405-50)." ASU 2022-04 is intended to establish disclosures that enhance the transparency of a supplier finance program used by an entity in connection with the purchase of goods and services. Supplier finance programs, which also may be referred to as

Share-Based Payment Arrangement [Abstract]
Schedule of fair value of the common stock warrants valuation assumptions	The Company calculates the fair value of each option grant on the grant date using the following assumptions: Expected Term — The Company uses the simplified method when calculating expected term due to insufficient historical exercise data. Expected Volatility — As the Company’s shares are not actively traded, the volatility is based on a benchmark of comparable companies within the automotive and energy storage industries. Expected Dividend Yield — The dividend rate used is zero as the Company does not have a history of paying dividends on its common stock and does not anticipate doing so in the foreseeable future. Risk-Free Interest Rate — The interest rates used are based on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term equal to the expected life of the award. Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Risk-free interest rate n/a 0.55 - 1.09% n/a 0.55– 1.09% Expected term (in years) n/a 5.47 - 6.07 n/a 5.47 – 6.07 Expected dividend yield n/a —% n/a —% Expected volatility n/a 36.88 -51.52% n/a 36.88 – 51.52%
