Amendment Description	On August 2, 2021, Enovix Corporation (the “Company”) filed a registration statement on Form S-1 (File No. 333-258358) (as amended, the “Registration Statement”) with the U.S. Securities and Exchange Commission (the “SEC”). The Registration Statement was declared effective by the SEC on August 9, 2021. Pursuant to the Registration Statement, the Company registered, among other things, its issuance of up to 11,500,000 shares of its common stock, $0.0001 par value per share (the “Common Stock”), issuable upon the exercise of 11,500,000 warrants originally issued in the initial public offering of Rodgers Silicon Valley Acquisition Corp. (the “Public Warrants”). On January 7, 2022, the Company redeemed all remaining unexercised Public Warrants in accordance with their terms. Accordingly, the Company has terminated all offerings of the 11,500,000 shares of Common Stock issuable upon the exercise of the Public Warrants. This Post-Effective Amendment No. 1 to Form S-1 (“Post-Effective Amendment No. 1”) is being filed in order to (i) remove from registration the 11,500,000 shares of Common Stock issuable upon exercise of the Public Warrants that were registered on the Registration Statement and (ii) include information contained in the Company’s Annual Report on Form 10-K for the fiscal year ended January 2, 2022 filed with the SEC on March 25, 2022 and Quarterly Report on Form 10-Q for the quarterly period ended April 3, 2022 filed with the SEC on May 18, 2022 and to update certain other information in the Registration Statement. The information included in this Post-Effective Amendment No. 1 amends the Registration Statement and the prospectus contained therein. No additional securities are being registered under this Post-Effective Amendment No. 1. All applicable registration fees were paid at the time of the original filing of the Registration Statement on August 2, 2021.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”). The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and the Business Combination from the Closing Date. All intercompany balances and transactions have been eliminated in consolidation. The Business Combination has been accounted for as a reverse recapitalization under GAAP. This determination is primarily based on Legacy Enovix stockholders comprising a relative majority of the voting power of Enovix and having the ability to nominate the members of the Board, Legacy Enovix’s operations prior to the acquisition comprising the only ongoing operations of Enovix, and Legacy Enovix’s senior management comprising a majority of the senior management of Enovix. Under this accounting method, RSVAC was treated as the “acquired” company and Legacy Enovix was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of Enovix represent a continuation of the financial statements of Legacy Enovix with the Business Combination being treated as the equivalent of Enovix issuing common stock for the net assets of RSVAC, accompanied by a recapitalization. The net liabilities of RSVAC, other than its warrant liabilities, were stated at historical cost, which approximates to its fair values. Its warrant liabilities were stated at its fair values and no goodwill or other intangible assets were recorded. Results of operations prior to the Business Combination are presented as those of Enovix. Beginning in the third quarter of 2021, historical shares and corresponding capital amounts, as well as for net loss per share, prior to the Business Combination, have been retrospectively adjusted using the exchange ratio as defined in the Business Combination for the equivalent number of shares outstanding immediately after the Business Combination to the effect the reverse recapitalization. The Company did not have any other comprehensive income or loss for the periods presented. Accordingly, net income (loss) and comprehensive income (loss) are the same for the periods presented. Additionally, the Company did not have any income tax expenses for the periods presented. Liquidity and Capital Resources The Company has incurred recurring operating losses and negative cash flows from operations since its inception through April 3, 2022 and expects to incur operating losses for the foreseeable future. As of April 3, 2022, the Company had a working capital of $398.1 million and an accumulated deficit of $290.4 million. In connection with the Business Combination in July 2021, the Company raised approximately $373.7 million of net proceeds, after deducting transaction costs and estimated offering related expenses. Please refer to Note 3 “Business Combination” of the notes to the consolidated financial statements for the fiscal year ended January 2, 2022 included in the Annual Report for more information. In December 2021, the Company received $77.2 million of gross proceeds from the exercises of the Public Warrants (as defined under the heading “Common Stock Warrants” in Note 7 “Warrants”), which were being traded in the Nasdaq Global Select Market (“Nasdaq”). In January 2022, the Company received $52.8 million of net proceeds from the exercise of the Public Warrants. The Company plans to use the proceeds from the exercises of the Public Warrants for general corporate purposes. Based on the anticipated spending, cash received from the Business Combination and timing of expenditures, the Company currently expects that its cash will be sufficient to meet its funding requirements over the next twelve months. Going forward, the Company may require additional financing for its future operation expansion. The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Unaudited Interim Condensed Consolidated Financial Statements The condensed consolidated balance sheet as of April 3, 2022, the condensed consolidated statements of operations, condensed consolidated statements of changes in shareholders’ equity for the quarters ended April 3, 2022 and March 31, 2021, and the condensed consolidated statements of cash flows for the quarters ended April 3, 2022 and March 31, 2021 are unaudited. These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring items, considered necessary to present fairly the Company’s financial condition, results of operations, stockholders’ equity and cash flows for the periods presented above. The results of operations for the quarter ended April 3, 2022 are not necessarily indicative of the operating results for the full year, and therefore should not be relied upon as an indicator of future results. The condensed consolidated balance sheet as of January 2, 2022 included herein was derived from the audited consolidated financial statements as of that date. The accompanying condensed consolidated financial statements and related notes included in the Annual Report. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the condensed consolidated financial statements and accompanying notes during the reporting periods. Estimates and assumptions include but are not limited to: depreciable lives for property and equipment, the valuation allowance on deferred tax assets, assumptions used in stock-based compensation, incremental borrowing rate for operating right-of-use pandemic on its critical and significant accounting estimates. There was no significant impact to its condensed consolidated financial statements. The Company will continue to evaluate the nature and extent of the potential impacts to its business and its condensed consolidated financial statements.

Other than the adoption of Accounting Standards Codification (“ASC”) 842, Leases, Recently Adopted Accounting Pronouncements Effective January 3, 2022, the Company adopted ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments 2016-13 2016-13	Note 2. Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and the Business Combination from the Closing Date. All intercompany balances and transactions have been eliminated in consolidation. The Business Combination has been accounted for as a reverse recapitalization under GAAP. This determination is primarily based on Legacy Enovix stockholders comprising a relative majority of the voting power of Enovix and having the ability to nominate the members of the Board, Legacy Enovix’s operations prior to the acquisition comprising the only ongoing operations of Enovix, and Legacy Enovix’s senior management comprising a majority of the senior management of Enovix. Under this accounting method, RSVAC was treated as the “acquired” company and Legacy Enovix was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of Enovix represent a continuation of the financial statements of Legacy Enovix with the Business Combination being treated as the equivalent of Enovix issuing common stock for the net assets of RSVAC, accompanied by a recapitalization. The net liabilities of RSVAC, other than its warrant liabilities, were stated at historical cost, which approximates to its fair value. Its warrant liabilities were stated at its fair values and no goodwill or other intangible assets were recorded. Results of operations prior to the Business Combination are presented as those of Enovix. Beginning in the third quarter of 2021, historical shares and corresponding capital amounts, as well as for net loss per share, prior to the Business Combination, were retrospectively adjusted using the exchange ratio as defined in the Business Combination for the equivalent number of shares outstanding immediately after the Business Combination to the effect the reverse recapitalization. The Company did not have any other comprehensive income or loss for the periods presented. Accordingly, net loss and comprehensive loss are the same for the periods presented. Additionally, the Company did not have any income tax expenses for the periods presented. Liquidity and Capital Resources The Company has incurred recurring operating losses and negative cash flows from operations since its inception through January 2, 2022 and expects to incur operating losses for the foreseeable future. As of January 2, 2022, the Company had a working capital of $377.5 million and an accumulated deficit of $333.2 million. Prior to the Business Combination, the Company had financed its operations primarily from the sales of convertible preferred stock, borrowing from convertible promissory notes, and borrowing from a secured promissory note (the “Secured Promissory Note”). In connection with the Business Combination in July 2021, the Company raised approximately $373.7 million of net proceeds, after deducting transaction costs and estimated offering related expenses. Please refer to Note 3 “Business Combination” for further details of the Business Combination. Based on the anticipated spending, cash received from the Business Combination and proceeds from the exercise of the Public Warrants, as well as the timing of expenditure assumptions, the Company currently expects that its cash will be sufficient to meet its funding requirements over the next twelve months. Going forward, the Company may require additional financing for its future operation expansion. If the Company is unsuccessful in its efforts to raise additional financing, the Company could be required to significantly reduce operating expenses and reduce its future commercialization efforts and sell unsecured assets, or a combination of the above, any of which may have a material adverse effect on the Company’s business, results of operations, financial condition and/or its ability to fund its scheduled obligations on a timely basis or at all. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the consolidated financial statements and accompanying notes as well as reported amounts of expenses during the reporting periods. Estimates and assumptions include but are not limited to: depreciable lives for property and equipment, the valuation allowance on deferred tax assets, assumptions used in stock-based compensation, incremental borrowing rate for operating right-of-use In the preparation of the Company’s consolidated financial statements, the Company has considered potential impacts of the COVID-19 Segment Reporting The Company operates in a single pre-production Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with original maturities from the date of purchase of 90 days or less to be cash equivalents. Restricted cash as of both January 2, 2022 and December 31, 2020 is comprised of a $0.1 million minimum cash balance required by the Company’s credit card merchant that can be cancelled with thirty days’ notice and is classified within Prepaid expenses and other current assets. Property and Equipment Property and equipment are stated at the Company’s original cost, net of accumulated depreciation. Construction in progress is related to the construction or development of property and equipment that have not yet been placed in service for their intended use. Depreciation is calculated using the straight-line method over the estimated useful lives of the following assets below. Leasehold improvements at the leased locations are amortized over the shorter of its lease term or its estimated useful lives. Useful Life (Years) Process equipment 5 Office equipment 5 Furniture and fixtures 5 Leasehold improvements Shorter of the economic life or the When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the Consolidated Statement of Operations in the period of disposition. Maintenance and repairs that do not improve or extend the lives of the respective assets are charged to expense in the period incurred. Capitalized Software Costs for Internal Use The Company capitalizes direct costs associated with developing or obtaining internal use software, including enterprise-wide business software, that are incurred during the application development stage. These capitalized costs are recorded as capitalized software within property and equipment. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Once the software is ready for its intended use, amounts capitalized are amortized over an estimated useful life of up to five years, generally on a straight-line basis. Capitalized software costs for internal use is included in office equipment category of the property and equipment on the Consolidated Balance Sheet. Impairment of Long-Lived Assets The Company evaluates the carrying value of long-lived assets when indicators of impairment exist. The carrying value of a long-lived asset is considered impaired when the estimated separately identifiable, undiscounted cash flows from such an asset are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using the estimated cash flows discounted at a rate commensurate with the risk involved. No impairment charges have been recorded in the periods presented above. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, 2016-02 right-of-use ASU 2016-02 Topic 842 Under Topic 842, the Company determines if an arrangement contains a lease and its lease classification at inception. For arrangements, with lease terms greater than 12 months and the Company is the lessee, right-of-use ROU assets also include any initial direct costs incurred and any lease payments made on or before the lease commencement date, less lease incentives received. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the lease liabilities as the Company’s leases generally do not provide an implicit rate. Lease terms may include options to extend or terminate the lease when the Company is reasonably certain that the option will be exercised. The Company combines the lease and non-lease Legacy Topic 840 Rent expense for non-cancelable Debt The Company accounts for the Secured Promissory Note as a liability measured at net proceeds less debt discount and is accreted to the face value of the Secured Promissory Note over its expected term using the effective interest method. The Company considers whether there are any embedded features in its debt instruments that require bifurcation and separate accounting as derivative financial instruments pursuant to Accounting Standards Codification (“ASC”), Topic 815, Derivatives and Hedging Convertible Promissory Notes In December 2019, the Company issued promissory notes that were convertible into preferred stock which were recorded at fair value at issuance and subject to re-measurement value recognized as a separate line item within other income (expense) in the Consolidated Statement of Operations. See Note 4 “Fair Value Measurement and Fair Value of Financial Instruments” and Note 7 “Debt” for more information. Convertible Preferred Stock Warrants The Company evaluated whether its warrants for shares of convertible preferred stock are freestanding financial instruments. The warrants were separately exercisable as the exercise of the warrants did not settle or extinguish the related convertible preferred stock. Additionally, the warrants were legally detachable from the related convertible preferred stock because the warrants might be transferred to another unaffiliated party without also transferring the related convertible preferred stock. As the warrants were freestanding financial instruments, they were liability classified. The warrants were recorded at fair value upon issuance as a non-current re-measurement Convertible Preferred Stock The Company recorded shares of convertible preferred stock at their respective fair values on the dates of issuance, net of issuance costs. The convertible preferred stock was recorded outside of stockholders’ equity (deficit) because, in the event of certain deemed liquidation events considered not solely within the Company’s control, such as a merger, acquisition and sale of all or substantially all of the Company’s assets, the convertible preferred stock would become redeemable at the option of the holders. In the event of a change of control of the Company, proceeds received from the sale of such shares would be distributed in accordance with the liquidation preferences set forth in the Company’s Amended and Restated Certificate of Incorporation. The Company did not adjust the carrying values of the convertible preferred stock to the liquidation preferences of such shares because of the uncertainty of whether or when such an event would occur. See Note 9 “Common Stock, Convertible Preferred Stock and Warrants” for more information on convertible preferred stock. Common Stock Warrants In connection with the Business Combination, the Company has issued and outstanding warrants of 17.5 million to purchase common stock at a price of $11.50 per share. The warrants expire five years from the completion of the Business Combination and are exercisable starting December 5, 2021. A portion of the outstanding warrants are held by the sponsor and members of Rodgers Capital LLC (the “Private Placement Warrants”) and the remaining warrants are held by other third-party investors (the “Public Warrants”). Once the warrants become exercisable, the Company may redeem for $0.01 per warrant the outstanding Public Warrants if the Company’s common stock price equals or exceeds $18.00 per share, subject to certain conditions and adjustments. Holders may elect to exercise their warrants on a cashless basis. The Private Placement Warrants are transferable, assignable or salable in certain limited exceptions. The Private Placement Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are non-redeemable The Company accounts for the warrants in accordance with ASC Topic 815, Derivative and Hedging The Public Warrants met the criteria for equity classification and were recorded as additional paid-in Fair Value of Financial Instruments The Company’s assets and liabilities, which require fair value measurement on a recurring basis, consist of Private Placement Warrants, convertible preferred stock warrants and convertible promissory notes recorded at fair value. Fair value principles require disclosures regarding the manner in which fair value is determined for assets and liabilities and establishes a three-tiered fair value hierarchy into which these assets and liabilities must be grouped, based upon significant levels of inputs as follows: • Level 1 — Observable inputs, such as quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date; • Level 2 — Observable inputs, other than Level 1 prices, such as quoted prices in active markets for similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. As of January 2, 2022 and December 31, 2020, the carrying values of cash and cash equivalents, accounts payable, accrued liabilities, and the convertible promissory notes approximated the fair value based on the short maturity of those instruments. As of December 31, 2020, convertible preferred stock warrants and convertible promissory notes were carried at fair value and were categorized as Level 3 measurements within the fair value hierarchy. As of January 2, 2022, Private Placement Warrants were carried at fair value and were categorized as Level 3 measurements. See Note 4 “Fair Value Measurement and Fair Value of Financial Instruments” for more information.​​​​​​​ Concentrations of Credit Risk and Major Customers Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company maintains cash and cash equivalent balances in checking, savings, and money market accounts at financial institutions. Amounts held in these accounts may exceed federally insured limits. As of January 2, 2022 and December 31, 2020, the Company has not experienced any losses on such deposits. For the fiscal years ended 2021 and 2020, one individual customer represented 64% and 91%, respectively, of the Company’s total deferred revenue. Revenue Recognition Effective January 1, 2019, the Company adopted ASC Topic 606, Revenue from Contracts with Customers Overall The Company generates revenue from payments received from its customers based on executed engineering revenue contracts (the “Service Revenue”) for the development of silicon-anode lithium-ion Service Revenue contracts generally include the design and development efforts to conform the Company’s existing battery technology with the customer’s required specifications. Consideration for Service Revenue contracts generally becomes payable when the Company meets specific contractual milestones, which include the design and approval of custom cells, procurement of fabrication tooling to meet the customer’s specifications, and fabrication and delivery of custom cells from the Company’s pilot production line. Within the existing Service Revenue contracts, the amount of consideration is fixed, the contracts contain a single performance obligation, and revenue is recognized at the point in time the final milestone is met (i.e., a final working prototype meeting all required specifications) and the customer obtains control of the deliverable. For the fiscal years 2021 and 2020, the Company did not recognize any Service Revenue as final milestones were not yet met. The Company does not recognize Service Revenue over-time because: (a) the customer does not simultaneously receive and consume the benefits of the Company’s efforts (only once the final prototype is delivered does the customer consume the benefits); (b) the Company’s performance does not create or enhance an asset that the customer controls as the asset is created or enhanced (because the customer does not have rights to the intellectual property); and (c) the Company’s performance creates an asset with an alternative use to the Company, as the Company could repurpose the work performed for other similar customers with little incremental effort. The amount and timing of revenue recognized is intended to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following steps: 1. Identify the contract with the customer The Company determines a contract with a customer to exist when (i) the contract is approved by the parties to the contract, (ii) each party’s rights regarding the goods or services to be transferred can be identified, (iii) the payment terms for the goods or services can be identified, (iv) the Company has been determined its customer has the intent and ability to pay, and (v) the contract has commercial substance (its expected future cash flows are expected to change as a result of the contract). The term of the Service Revenue contracts generally last from one 2. Identify the performance obligations in the contract performance obligation is a promise to provide a distinct good or service or a series of distinct goods or services. A good or service that is promised to a customer is distinct if the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and a company’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Service Revenue contracts generally contain promises, which include (a) designing battery prototypes to customer specifications (b) status updates (c) testing (d) prototype milestones, and (e) delivery of final battery protypes per the customers specifications. Generally, the Company will own all intellectual property that is developed and directed toward the Company’s silicon-anode lithium-ion 3. Determine the transaction price Transaction price is determined based on the amount of consideration to which the Company expects to be entitled in exchange for the promised goods or services. Service Revenue contracts are for a fixed amount that will be paid to the Company assuming it fulfills milestone obligations under the contract. Generally, there is no consideration within the Service Revenue contracts that are variable. 4. Allocate the transaction price to the performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. As the Service Revenue contracts only contains a single performance obligation, the Company will allocate 100% of the contract consideration to the single performance obligation. 5. Recognize revenue when, or as, a performance obligation is satisfied Service Revenue is recognized when control of the goods or services is transferred to the customer. For Service Revenue contracts, control transfers upon the shipment of the final production ready prototype unit. Although the Company is entitled to milestone payments as it meets each milestone and such payments are non-refundable, Sales and Transaction Taxes Sales and other taxes collected from customers and remitted to governmental authorities on revenue-producing transactions are reported on a net basis and are therefore excluded from revenues in the Consolidated Statement of Operations. Deferred Revenue Deferred revenue represents situations where the Company has the contractual right to invoice, or cash is collected, but the related revenue has not yet been recognized. Revenue is subsequently recognized when the revenue recognition criteria are met. Service Revenue is generally invoiced based on pre-defined Costs to Fulfill a Customer Contract The revenue recognition standard requires capitalization of certain costs to fulfil a customer contract, such as certain employee compensation for design and development services that specifically relate to customer contracts. Costs are recognized as an asset if they relate directly to a customer contract, generate or enhance resources of the entity that will be used in satisfying future performance obligations, and are expected to be recovered. If these three criteria are not met, the costs are expensed in the period incurred. Deferred costs are recognized as cost of revenue in the period when the related revenue is recognized. As of January 2, 2022 and December 31, 2020, total deferred contract costs were $4.6 million and $3.5 million, respectively. Cost of Revenues Cost of revenues includes materials, labor, allocated depreciation expense, and other direct costs related to Service Revenue contracts. Labor consists of personnel-related expenses such as salaries, benefits, and stock-based compensation. Cost of revenue represents costs incurred on certain Service Revenue contracts that was in excess of the amount expected to be recovered. Research and Development Costs Research and development costs consist of engineering services, allocated facilities costs, depreciation, development expenses, materials, labor and stock-based compensation related primarily to the Company’s (i) technology development, (ii) design, construction, and testing of preproduction prototypes and models, and (iii) certain costs related to the design, construction, and operation of its pilot plant that is not of a scale economically feasible to the Company for commercial production. Research and development costs are expensed as incurred. Selling, General and Administrative Expenses Selling, general and administrative expenses consist of personnel-related expenses, marketing expenses, allocated facilities expenses, depreciation expenses, executive management travel, and professional services expenses, including legal, human resources, audit, accounting and tax-related Merger Transaction Costs During the fiscal year ended January 2, 2022, the Company incurred significant direct and incremental transaction costs related to the recently completed merger with RSVAC. These transaction costs were first deferred and capitalized to the deferred transaction costs, non-current paid-in Government Grant In September 2020, the Company entered into a financial assistance agreement totaling $6.5 million with the Office of Energy Efficiency and Renewable Energy (“EERE”), an office within the U.S. Department of Energy. Under the agreement, the Company will perform research and development under a joint project with the EERE, and the EERE will reimbursee the Company for 49.8% of allowable project costs. The remaining 50.2% in costs would be incurred by the Company. The Company accounts for funds which are probable of being received in the same period in which the costs were incurred as an offset to the related expense (Research and development) or capitalized asset (Property and equipment, net). As of January 2, 2022 and December 31, 2020, the Company had a reimbursement receivable from the assistance agreement of $0.3 million and $0.2 million, which is included in Prepaid expenses and other current assets. Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes, In addition, ASC 740 provides comprehensive guidance on the recognition and measurement of tax positions in previously filed tax returns or positions expected to be taken in future tax returns. The benefit from an uncertain tax position must meet a more-likely-than-not Stock-Based Compensation The Company issues stock-based compensation to employees and non-employees Restricted Stock Units Starting non-employees Stock options Generally, the stock options have a maximum contractual term up to 10 years. The fair value of stock options is based on the date of the grant using the Black-Scholes valuation method. The awards are accounted for by recognizing the fair value of the related award over the period during which services are provided in exchange for the award (referred to as the requisite service period, which typically equals the vesting period of the award). The vesting period is generally four or five years. No stock awards have been issued with a market condition or other performance vesting condition. In accordance with ASU 2018-07 non-employee Fair Value of Common Stock and Stock Option Prior to the completion of the Business Combination, the fair value of the Company’s common stock underlying stock options was determined by the Company’s board of directors. Given the absence of a public trading market, the board of directors considered numerous objective and subjective factors to determine the fair value of the Company’s common stock at each board of directors meeting in which stock awards were approved. These factors included, but were not limited to: (i) contemporaneous third-party valuations of common stock; (ii) the rights, preferences, and privileges of convertible preferred stock relative to common stock; (iii) the lack of marketability of common stock; (iv) stage and development of the Company’s business; (v) general economic conditions; and (vi) the likelihood of achieving a liquidity event, such as an initial public offering, or sale of the Company, given prevailing market conditions. Based on the valuation reports from the third-party and the relevant factors as discussed above, the Company determined the fair value per share of the underlying common stock of the stock options. The following assumptions are used in the Black-Scholes valuation model for the fair value of stock options per share. • Expected Term — The expected term of the options represents the average period the share options are expected to remain outstanding. As the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior, the expected term of options granted is derived from the average midpoint between the weighted average vesting and the contractual term, also known as the simplified method. The Company uses the simplified calculation of the expected life, which takes into consideration the grant’s contractual life and vesting period and assumes that all options will be exercised between the vesting date and the contractual term of the option. • Risk-Free Interest Rate — The risk-free interest rate is based on the yield of U.S. Treasury notes as of the grant date with terms commensurate with the expected term of the option. • Dividend Yield — The expected dividends assumption is based on the Company’s expectation of not paying dividends in the foreseeable future, as well as the Company did not pay any dividends in the past. • Volatility — Prior to the Business Combination, Legacy Enovix was a private company and did not have any trading history for its ordinary shares, the expected volatility was based on the historical volatilities of the common stock of comparable publicly traded companies that Legacy Enovix selected with comparable characteristics, including enterprise value, risk profiles, position within the industry, and with historical share price information sufficient to meet the expected life of the Legacy Enovix’s stock options. Net Loss per Share of Common Stock Basic net loss per share of common stock is calculated using the two-class non-forfeitable 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. Unvested early exercised stock options are not considered outstanding for purposes of the weighted average outstanding share calculation until they vest. Diluted earnings per share (“EPS”) attributable to common stockholders adjusts basic EPS for the potentially dilutive impact of the participating securities. As the Company has reported losses for the periods presented, all potentially dilutive securities including convertible preferred stock, stock options and warrants, are generally antidilutive and accordingly, basic net loss per share equals diluted net loss per share, except when there were changes in fair value of the Private Placement Warrants recorded in earnings. With changes in fair value recorded in earnings, an adjustment would be made to both the diluted EPS numerator and denominator to eliminate such effects. Emerging Growth Company Status The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGC’s can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. Other than the adoption of ASC 842, Leases, Revenue from Contracts with Customers Recently Adopted Accounting Pronouncements In December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes taxes. ASU 2019-12 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . 2016-02 right-of-use . The guidance requires lessees to recognize all leases, with certain exceptions, on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee must recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. On January 1, 2021, the Company early adopted ASU 2016-02 using the modified retrospective transition option of applying the new standard at the adoption date for all leases with terms greater than 12 months. The Company elected certain practical expedients upon adoption and as such did not reassess the following: 1) whether any expired or existing contracts are or contain leases; 2) lease classification for any expired or existing leases; 3) initial direct costs for any expired or existing leases; 4) whether existing or expired land easements are or contain leases; and 5) regarding the lease term, from a hindsight perspective, whether or not the Company is reasonably certain to exercise the lease options. The Company also elected the practical expedient to not separate lease and non-lease components. The effect of the adoption of ASC 842 on the Consolidated Balance Sheet as of January 1, 2021 was as follows (in thousands): December 31, Adjustments January 1, Operating lease, right-of-use $ — $ 6,873 $ 6,873 Other liabilities 14 (14 ) — Deferred rent, non-current 1,567 (1,567 ) — Operating lease liabilities, non-current — 8,551 8,551 Periods prior to the January 1, 2021 adoption of ASC 842 were not adjusted and continue to be reported in accordance with the legacy lease accounting guidance under ASC 840.

Business Combinations [Abstract]
Business Combination	Note 3. Business Combination As described in Note 1, on July 14, 2021, Legacy Enovix, RSVAC, and Merger Sub, consummated the closing of the transactions contemplated by the Merger Agreement, following the approval at the Special Meeting held on July 12, 2021. Immediately prior to the Business Combination all shares of Legacy Enovix outstanding convertible preferred stock were converted into an equivalent number of shares of Legacy Enovix common stock. At the Business Combination, eligible Legacy Enovix equity holders received or have the right to receive shares of Enovix common stock (“Common Stock”), with par value $0.0001 per share, at a deemed value of $10.00 per share after giving effect to the exchange ratio of approximately 0.1846 as defined in the Merger Agreement (“Exchange Ratio”). Accordingly, immediately following the consummation of the Business Combination, Legacy Enovix common stock was exchanged into 103,995,643 shares of Common Stock, 5,547,327 shares were reserved for the issuance of Common Stock upon the potential future exercise of Legacy Enovix’s stock options that were exchanged into Enovix’s stock options. Upon the closing of the Business Combination, the Company’s certificate of incorporation was amended and restated to, among other things, increase the total number of authorized shares of Common Stock to 1,000,000,000 shares, $0.0001 par value per share and designate 10,000,000 shares as Preferred Stock. In connection with the execution of the Merger Agreement, RSVAC entered into separate subscription agreements (each a “Subscription Agreement”) with a number of investors (each a “New PIPE Investor”), pursuant to which the New PIPE Investors agreed to purchase, and RSVAC agreed to sell to the New PIPE Investors, an aggregate of 12,500,000 shares of Common Stock (“PIPE Shares”), for a purchase price of $14.00 per share and an aggregate purchase price of $175.0 million, in a private placement pursuant to the subscription agreements (“PIPE Financing”). The PIPE Financing closed simultaneously with the consummation of the Business Combination. The number of shares of Common Stock issued immediately following the consummation of the Business Combination was: RSVAC common stock shares outstanding prior to the Business Combination 28,750,000 Less redemption of RSVAC common stock shares (15 ) RSVAC common stock shares 28,749,985 PIPE Shares issued 12,500,000 RSVAC common stock shares and PIPE Shares 41,249,985 Legacy Enovix common shares (1) 103,995,643 Total shares of Common Stock immediately after the Business Combination 145,245,628 (1) The number of Legacy Enovix common shares was determined from the 563,316,738 shares of Legacy Enovix common stock outstanding immediately prior to the closing of the Business Combination converted at the exchange ratio of approximately 0.1846 . All fractional shares were rounded. The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, RSVAC was treated as the “acquired” company and Legacy Enovix is treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Enovix issuing stock for the net assets of RSVAC, accompanied by a recapitalization. The net assets of RSVAC were stated at historical cost, with no goodwill or other intangible assets recorded. In connection with the Business Combination in July 2021, the Company assumed $ million of net liabilities from RSVAC. The following table shows the net cash proceeds from the Business Combination (in thousands): Recapitalization Cash — RSVAC Trust and cash, net of redemptions $ 230,155 Cash — PIPE Financing 175,000 Less: transaction costs and PIPE financing fees (31,410 ) Net cash contributions from Business Combination $ 373,745

Fair Value Disclosures [Abstract]
Fair Value Measurement and Fair Value of Financial Instruments	Note 3. Fair Value Measurement The fair value of the Company’s financial assets and liabilities are determined in accordance with the fair value hierarchy established in ASC 820, Fair Value Measurements, value hierarchy of ASC 820 requires an entity to maximize the use of observable inputs when measuring fair value and classifies those inputs into three levels: Level 1: Observable inputs, such as quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date. Level 2: Observable inputs, other than Level 1 prices, such as quoted prices in active markets for similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Fair Value Measurement and Fair Value of Financial Instruments The fair value of the Company’s financial assets and liabilities are determined in accordance with the fair value hierarchy established in ASC 820, Fair Value Measurements, Level 1: Observable inputs, such as quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date. Level 2: Observable inputs, other than Level 1 prices, such as quoted prices in active markets for similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our financial instruments consist primarily of cash and cash equivalents, accounts payable and the warrant liabilities. Cash and cash equivalents are reported at their respective fair values on our balance sheets. Where quoted prices are available in an active market, securities are classified as Level 1. The Company classifies money market funds as Level 1. When quoted market prices are not available for the specific security, then the Company estimates fair value by using quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs obtained from various third-party data providers, including but not limited to benchmark yields, reported trades and broker/dealer quotes. Where applicable the market approach utilizes prices and information from market transactions for similar or identical assets. The Company will classify commercial paper, corporate debt securities and asset-backed securities as Level 2. As of January 2, 2022 and December 31, 2020, the Company did not have short-term and long-term investments that are classified available-for-sale.

The number of shares underlying Legacy Enovix Series D convertible preferred stock warrants as of December 31, 2020 on an ‘as-converted ‘as-converted Detail related to warrant activity for the fiscal year ended December 31, 2020, is as follows: Convertible Preferred Stock Warrants Number of Weighted Balances as of January 1, 2020 3,342,780 $ 0.07 Granted 7,000,000 0.01 Exercised — — Cancelled (181,844 ) 1.10 Balances as of December 31, 2020 10,160,936 $ 0.01 On February 22, 2021, in a transaction separate from the Merger Agreement, the then outstanding Legacy Enovix Series D convertible preferred stock warrants were exercised at $0.01 per share, resulting in the issuance of 10,160,936 shares of Legacy Enovix Series D convertible preferred stock to the holders of such warrants, for a total of $0.1 million. As of January 2, 2022, there were no convertible preferred stock warrants outstanding. Common Stock Warrants In connection with the Business Combination, the Company has assumed 17,500,000 Common Stock Warrants outstanding, which consisted of 11,500,000 Public Warrants Public Warrants As of January 2, 2022, the Company had 4,322,106 Public Warrants outstanding. Each whole Public Warrant entitles the registered holder to purchase one share of the Company’s Common stock at a price of $11.50 per share, subject to the following conditions discussed below. The Public Warrants became exercisable on the later of (a) 30 days after the completion of the Business Combination or (b) 12 months from the closing of the initial public offering (“IPO”) of RSVAC. The common stock warrants expired five years after the completion of a Business Combination or earlier upon redemption or liquidation. The Company filed with the SEC a registration statement for the registration under the Securities Act of the shares of common stock issuable upon exercise of the warrants and has caused the same to become effective. The Company used its best efforts to maintain a current prospectus relating to the common stock issuable upon exercise of the warrants, until the expiration of the warrants in accordance with the provisions of the warrant agreement. Once the Public Warrants become exercisable, the Company may redeem the Public 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 the common stock equals or exceeds $18.00 per share, for any 20 trading days within a 30 trading day period ending on the third trading day prior to the notice of redemption to the warrant holders. The right to exercise was forfeited unless the Public Warrants were exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a Public Warrant had no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant. If the Company called the Common Stock Warrants for redemption as described above, management would have the option to require all holders that wish to exercise the Common Stock Warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the Common Stock Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Common Stock Warrants, multiplied by the difference between the exercise price of the Common Warrants and the “fair market value” as defined below by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of its 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 Common Stock Warrants. Whether the Company exercised its option to require all holders to exercise the Common Stock Warrants on a “cashless basis” depended on a variety of factors including the price of its Common Stock at the time the Common Stock Warrants were called for redemption, the Company’s cash needs at such time and concerns regarding dilutive share issuances. The exercise price and number of shares of Common Stock issuable upon exercise of the Common Stock Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or the Company’s recapitalization, reorganization, merger or consolidation. However, the Common Stock Warrants would not be adjusted for issuances of shares of Common Stock at a price below their respective exercise prices. On December 7, 2021, the Company delivered the notice of redemption to the holders of the outstanding Public Warrants to redeem all of its outstanding Public Warrants. The holders of the Public Warrants had until January 7, 2022 to exercise their Public Warrants. Any pubic warrants that remained unexercised after 5:00 pm, New York City Time, on January 7, 2022 were voided and were no longer exercisable, and the holders of the Public Warrants would be entitled to receive $0.01 per warrant. Detail related to Public Warrant activity for the fiscal year ended January , , is as follows: Public Warrants Number of Weighted Balances as of January 1, 2021 — $ — Assumed through the Business Combination 11,499,991 11.50 Exercised (7,177,885 ) 11.50 Balances as of January 2, 2022 4,322,106 $ 11.50 For the fiscal year 2021, 7,177,855 Public Warrants were exercised with the gross proceeds of $82.5 million, of which the Company received payments of $77.2 million and the remaining $5.3 million was considered as other receivable included in Prepaid and Other Current Assets of the Consolidated Balance Sheet as of January 2, 2022. See Note 15 “Subsequent Events” for more information on exercises of the Public Warrants after January 2, 2022. Private Placement Warrant The 6,000,000 Private Placement Warrants were originally issued in a private placement to the initial stockholder of Rodgers Capital, LLC (the “Sponsor”) in connection with the initial public offering of RSVAC. Each whole Private Placement Warrant became exercisable for one whole share of the Company’s common stock at a price of $11.50 per share on December 5, 2021. As of January 2, 2022, the Company had 6,000,000 Private Placement Warrants outstanding. The Private Placement Warrants are identical to the Public Warrants underlying the units except that such Private Placement Warrants will be exercisable on a cashless basis, at the holder’s option, and will not be redeemable by us, in each case so long as they are still held by the initial purchasers or their affiliates. The Private Placement Warrants purchased by our Sponsor will not be exercisable more than five years from the effective date of the RSVAC IPO registration statement, in accordance with FINRA Rule 5110(f)(2)(G)(i), as long as Rodgers Capital, LLC or any of its related persons beneficially own these Private Placement Warrants. On September 8, 2021, the Sponsor made an in-kind As of January 2, 2022, the remaining contractual term for the outstanding Private Placement Warrants to purchase our common stock is years.

Accordingly, the diluted net loss per share of common stock was the same as basic net loss per share of common stock. In connection with the Business Combination, shares of the Company’s common stock and all potentially dilutive securities for the prior periods were retroactively adjusted based on the exchange ratio established in the Business Combination.

Income Tax	Note 13. Income Tax The following table discloses net loss before income taxes is attributable to the following geographic locations for the fiscal years 2021 and 2020 (in thousands). Fiscal Years 2021 2020 United States $ (125,797 ) $ (39,637 ) Foreign (77 ) (13 ) Net loss before income taxes $ (125,874 ) $ (39,650 ) During the fiscal years 2021, and 2020, there was no provision for income taxes recorded as the Company generated net operating losses. The difference between the effective tax rate and the U.S. federal statutory tax rate for the fiscal years 2021, and 2020 are as follows: Fiscal Years 2021 2020 Federal statutory tax rate 21.0 % 21.0 % State and local income taxes, net of federal benefit 3.7 % 4.3 % Change in fair value of convertible promissory notes — % (1.3 %) Non-deductible (9.4 %) (8.1 %) Federal tax credits 0.3 % 0.5 % Share-based compensation (0.8 %) (0.3 %) Extinguishment of PPP Loan — % 0.9 % Impact of changes in valuation allowance (14.6 %) (16.9 %) Other (0.2 %) (0.1 %) Effective tax rate — % — % Deferred tax assets (liabilities) as of January 2, 2022 and December 31, 2020 consist of the following: January 2, December 31, Gross deferred tax assets: Deferred rent $ — $ 442 Lease liabilities 2,687 — Deferred revenue 2,201 1,538 Share-based compensation 1,769 346 Federal and state credit carryovers 4,604 3,994 Federal and state net operating losses 63,522 48,934 Transaction costs 1,656 — Depreciation and amortization 250 — Total gross deferred tax assets 76,689 55,254 Valuation allowance (74,823 ) (54,734 ) Total deferred tax assets, net of valuation allowance 1,866 520 Deferred tax liabilities: Depreciation and amortization — (520 ) Right-of-use (1,866 ) — Total deferred tax liabilities (1,866 ) (520 ) Net deferred tax assets $ — $ — As of January 2, 2022, the Company had $226.3 million of state and $227.2 million of federal loss carryovers that could be utilized to reduce the tax liabilities of future years. The tax-effected The state losses expire between 2028 and 2041. Approximately $127.9 million of the federal losses expire between 2026 and 2037 and the remainder do not expire. The federal credit carryovers expire between 2027 and 2041. The state credit carryovers do not expire. Utilization of net operating losses and tax credit carryforwards are subject to certain limitations under Section 382 of the Internal Revenue Code of 1986, as amended, in the event of a change in the Company’s ownership, as defined in current income tax regulations. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. Significant judgement is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, the Company considers all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies. In the event the Company changes its determination as to the amount of deferred tax assets that can be realized, it will adjust the valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. As of January 2, 2022, the Company recognized a full valuation allowance against its U.S. federal and state net deferred tax assets, including operating loss carryovers and credit carryovers. The Company evaluated the realizability of its net deferred tax assets based on all available evidence, both positive and negative, which existed as of January 2, 2022. The Company’s conclusion to maintain a full valuation allowance against its net deferred tax assets was based upon the assessment of its ability to generate sufficient future taxable income in future periods. The activity related to unrecognized tax benefits for the fiscal years 2021, and 2020 are as follows: Fiscal Years 2021 2020 Balance at beginning of fiscal year $ 4,368 $ 3,974 Increases related to current year tax positions 537 394 Increases related to the prior year tax positions 143 — Balance at end of fiscal year $ 5,048 $ 4,368 As of January 2, 2022 and December 31, 2020, none of the amounts of unrecognized tax benefits would favorably affect the effective income tax rate in future periods if recognized, since the tax benefits would increase a deferred tax asset that is currently offset by a full valuation allowance. As of January 2, 2022, the Company has not identified any unrecognized that benefits where it is reasonably possible that it will recognize a decrease within the next 12 months. If the Company does recognize such a decrease, the net impact on the Consolidated Statement of Operations would not be material. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense on the Consolidated Statement of Operations. For the fiscal years 2021, and 2020, no interest expense was recognized relating to income tax liabilities. There were no accrued interest or penalties related to income tax liabilities as of January 2, 2022 and December 31, 2020. The Company files income tax returns in the U.S. federal jurisdiction and in the California state jurisdiction. In the normal course of business, the Company is subject to examination by taxing authorities in the U.S. The Company is not currently under examination by any taxing authority.

Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”). The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and the Business Combination from the Closing Date. All intercompany balances and transactions have been eliminated in consolidation. The Business Combination has been accounted for as a reverse recapitalization under GAAP. This determination is primarily based on Legacy Enovix stockholders comprising a relative majority of the voting power of Enovix and having the ability to nominate the members of the Board, Legacy Enovix’s operations prior to the acquisition comprising the only ongoing operations of Enovix, and Legacy Enovix’s senior management comprising a majority of the senior management of Enovix. Under this accounting method, RSVAC was treated as the “acquired” company and Legacy Enovix was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of Enovix represent a continuation of the financial statements of Legacy Enovix with the Business Combination being treated as the equivalent of Enovix issuing common stock for the net assets of RSVAC, accompanied by a recapitalization. The net liabilities of RSVAC, other than its warrant liabilities, were stated at historical cost, which approximates to its fair values. Its warrant liabilities were stated at its fair values and no goodwill or other intangible assets were recorded. Results of operations prior to the Business Combination are presented as those of Enovix. Beginning in the third quarter of 2021, historical shares and corresponding capital amounts, as well as for net loss per share, prior to the Business Combination, have been retrospectively adjusted using the exchange ratio as defined in the Business Combination for the equivalent number of shares outstanding immediately after the Business Combination to the effect the reverse recapitalization. The Company did not have any other comprehensive income or loss for the periods presented. Accordingly, net income (loss) and comprehensive income (loss) are the same for the periods presented. Additionally, the Company did not have any income tax expenses for the periods presented.

Segment Reporting		Segment Reporting The Company operates in a single pre-production
Cash, Cash Equivalents and Restricted Cash		Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with original maturities from the date of purchase of 90 days or less to be cash equivalents. Restricted cash as of both January 2, 2022 and December 31, 2020 is comprised of a $0.1 million minimum cash balance required by the Company’s credit card merchant that can be cancelled with thirty days’ notice and is classified within Prepaid expenses and other current assets.
Property and Equipment		Property and Equipment Property and equipment are stated at the Company’s original cost, net of accumulated depreciation. Construction in progress is related to the construction or development of property and equipment that have not yet been placed in service for their intended use. Depreciation is calculated using the straight-line method over the estimated useful lives of the following assets below. Leasehold improvements at the leased locations are amortized over the shorter of its lease term or its estimated useful lives. Useful Life (Years) Process equipment 5 Office equipment 5 Furniture and fixtures 5 Leasehold improvements Shorter of the economic life or the When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in the Consolidated Statement of Operations in the period of disposition. Maintenance and repairs that do not improve or extend the lives of the respective assets are charged to expense in the period incurred.
Capitalized Software Costs for Internal Use		Capitalized Software Costs for Internal Use The Company capitalizes direct costs associated with developing or obtaining internal use software, including enterprise-wide business software, that are incurred during the application development stage. These capitalized costs are recorded as capitalized software within property and equipment. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Once the software is ready for its intended use, amounts capitalized are amortized over an estimated useful life of up to five years, generally on a straight-line basis. Capitalized software costs for internal use is included in office equipment category of the property and equipment on the Consolidated Balance Sheet.
Impairment of Long-Lived Assets		Impairment of Long-Lived Assets The Company evaluates the carrying value of long-lived assets when indicators of impairment exist. The carrying value of a long-lived asset is considered impaired when the estimated separately identifiable, undiscounted cash flows from such an asset are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using the estimated cash flows discounted at a rate commensurate with the risk involved. No impairment charges have been recorded in the periods presented above.
Leases		Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, 2016-02 right-of-use ASU 2016-02 Topic 842 Under Topic 842, the Company determines if an arrangement contains a lease and its lease classification at inception. For arrangements, with lease terms greater than 12 months and the Company is the lessee, right-of-use ROU assets also include any initial direct costs incurred and any lease payments made on or before the lease commencement date, less lease incentives received. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the lease liabilities as the Company’s leases generally do not provide an implicit rate. Lease terms may include options to extend or terminate the lease when the Company is reasonably certain that the option will be exercised. The Company combines the lease and non-lease Legacy Topic 840 Rent expense for non-cancelable
Debt		Debt The Company accounts for the Secured Promissory Note as a liability measured at net proceeds less debt discount and is accreted to the face value of the Secured Promissory Note over its expected term using the effective interest method. The Company considers whether there are any embedded features in its debt instruments that require bifurcation and separate accounting as derivative financial instruments pursuant to Accounting Standards Codification (“ASC”), Topic 815, Derivatives and Hedging
Convertible Promissory Notes		Convertible Promissory Notes In December 2019, the Company issued promissory notes that were convertible into preferred stock which were recorded at fair value at issuance and subject to re-measurement value recognized as a separate line item within other income (expense) in the Consolidated Statement of Operations. See Note 4 “Fair Value Measurement and Fair Value of Financial Instruments” and Note 7 “Debt” for more information.
Convertible Preferred Stock Warrants		Convertible Preferred Stock Warrants The Company evaluated whether its warrants for shares of convertible preferred stock are freestanding financial instruments. The warrants were separately exercisable as the exercise of the warrants did not settle or extinguish the related convertible preferred stock. Additionally, the warrants were legally detachable from the related convertible preferred stock because the warrants might be transferred to another unaffiliated party without also transferring the related convertible preferred stock. As the warrants were freestanding financial instruments, they were liability classified. The warrants were recorded at fair value upon issuance as a non-current re-measurement
Convertible Preferred Stock		Convertible Preferred Stock The Company recorded shares of convertible preferred stock at their respective fair values on the dates of issuance, net of issuance costs. The convertible preferred stock was recorded outside of stockholders’ equity (deficit) because, in the event of certain deemed liquidation events considered not solely within the Company’s control, such as a merger, acquisition and sale of all or substantially all of the Company’s assets, the convertible preferred stock would become redeemable at the option of the holders. In the event of a change of control of the Company, proceeds received from the sale of such shares would be distributed in accordance with the liquidation preferences set forth in the Company’s Amended and Restated Certificate of Incorporation. The Company did not adjust the carrying values of the convertible preferred stock to the liquidation preferences of such shares because of the uncertainty of whether or when such an event would occur. See Note 9 “Common Stock, Convertible Preferred Stock and Warrants” for more information on convertible preferred stock.
Common Stock Warrants		Common Stock Warrants In connection with the Business Combination, the Company has issued and outstanding warrants of 17.5 million to purchase common stock at a price of $11.50 per share. The warrants expire five years from the completion of the Business Combination and are exercisable starting December 5, 2021. A portion of the outstanding warrants are held by the sponsor and members of Rodgers Capital LLC (the “Private Placement Warrants”) and the remaining warrants are held by other third-party investors (the “Public Warrants”). Once the warrants become exercisable, the Company may redeem for $0.01 per warrant the outstanding Public Warrants if the Company’s common stock price equals or exceeds $18.00 per share, subject to certain conditions and adjustments. Holders may elect to exercise their warrants on a cashless basis. The Private Placement Warrants are transferable, assignable or salable in certain limited exceptions. The Private Placement Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are non-redeemable The Company accounts for the warrants in accordance with ASC Topic 815, Derivative and Hedging The Public Warrants met the criteria for equity classification and were recorded as additional paid-in
Fair Value of Financial Instruments		Fair Value of Financial Instruments The Company’s assets and liabilities, which require fair value measurement on a recurring basis, consist of Private Placement Warrants, convertible preferred stock warrants and convertible promissory notes recorded at fair value. Fair value principles require disclosures regarding the manner in which fair value is determined for assets and liabilities and establishes a three-tiered fair value hierarchy into which these assets and liabilities must be grouped, based upon significant levels of inputs as follows: • Level 1 — Observable inputs, such as quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date; • Level 2 — Observable inputs, other than Level 1 prices, such as quoted prices in active markets for similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. As of January 2, 2022 and December 31, 2020, the carrying values of cash and cash equivalents, accounts payable, accrued liabilities, and the convertible promissory notes approximated the fair value based on the short maturity of those instruments. As of December 31, 2020, convertible preferred stock warrants and convertible promissory notes were carried at fair value and were categorized as Level 3 measurements within the fair value hierarchy. As of January 2, 2022, Private Placement Warrants were carried at fair value and were categorized as Level 3 measurements. See Note 4 “Fair Value Measurement and Fair Value of Financial Instruments” for more information.​​​​​​​
Concentrations of Credit Risk and Major Customers		Concentrations of Credit Risk and Major Customers Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company maintains cash and cash equivalent balances in checking, savings, and money market accounts at financial institutions. Amounts held in these accounts may exceed federally insured limits. As of January 2, 2022 and December 31, 2020, the Company has not experienced any losses on such deposits. For the fiscal years ended 2021 and 2020, one individual customer represented 64% and 91%, respectively, of the Company’s total deferred revenue.
Revenue Recognition		Revenue Recognition Effective January 1, 2019, the Company adopted ASC Topic 606, Revenue from Contracts with Customers Overall The Company generates revenue from payments received from its customers based on executed engineering revenue contracts (the “Service Revenue”) for the development of silicon-anode lithium-ion Service Revenue contracts generally include the design and development efforts to conform the Company’s existing battery technology with the customer’s required specifications. Consideration for Service Revenue contracts generally becomes payable when the Company meets specific contractual milestones, which include the design and approval of custom cells, procurement of fabrication tooling to meet the customer’s specifications, and fabrication and delivery of custom cells from the Company’s pilot production line. Within the existing Service Revenue contracts, the amount of consideration is fixed, the contracts contain a single performance obligation, and revenue is recognized at the point in time the final milestone is met (i.e., a final working prototype meeting all required specifications) and the customer obtains control of the deliverable. For the fiscal years 2021 and 2020, the Company did not recognize any Service Revenue as final milestones were not yet met. The Company does not recognize Service Revenue over-time because: (a) the customer does not simultaneously receive and consume the benefits of the Company’s efforts (only once the final prototype is delivered does the customer consume the benefits); (b) the Company’s performance does not create or enhance an asset that the customer controls as the asset is created or enhanced (because the customer does not have rights to the intellectual property); and (c) the Company’s performance creates an asset with an alternative use to the Company, as the Company could repurpose the work performed for other similar customers with little incremental effort. The amount and timing of revenue recognized is intended to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To achieve this core principle, the Company applies the following steps: 1. Identify the contract with the customer The Company determines a contract with a customer to exist when (i) the contract is approved by the parties to the contract, (ii) each party’s rights regarding the goods or services to be transferred can be identified, (iii) the payment terms for the goods or services can be identified, (iv) the Company has been determined its customer has the intent and ability to pay, and (v) the contract has commercial substance (its expected future cash flows are expected to change as a result of the contract). The term of the Service Revenue contracts generally last from one 2. Identify the performance obligations in the contract performance obligation is a promise to provide a distinct good or service or a series of distinct goods or services. A good or service that is promised to a customer is distinct if the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and a company’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Service Revenue contracts generally contain promises, which include (a) designing battery prototypes to customer specifications (b) status updates (c) testing (d) prototype milestones, and (e) delivery of final battery protypes per the customers specifications. Generally, the Company will own all intellectual property that is developed and directed toward the Company’s silicon-anode lithium-ion 3. Determine the transaction price Transaction price is determined based on the amount of consideration to which the Company expects to be entitled in exchange for the promised goods or services. Service Revenue contracts are for a fixed amount that will be paid to the Company assuming it fulfills milestone obligations under the contract. Generally, there is no consideration within the Service Revenue contracts that are variable. 4. Allocate the transaction price to the performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. As the Service Revenue contracts only contains a single performance obligation, the Company will allocate 100% of the contract consideration to the single performance obligation. 5. Recognize revenue when, or as, a performance obligation is satisfied Service Revenue is recognized when control of the goods or services is transferred to the customer. For Service Revenue contracts, control transfers upon the shipment of the final production ready prototype unit. Although the Company is entitled to milestone payments as it meets each milestone and such payments are non-refundable, Sales and Transaction Taxes Sales and other taxes collected from customers and remitted to governmental authorities on revenue-producing transactions are reported on a net basis and are therefore excluded from revenues in the Consolidated Statement of Operations. Deferred Revenue Deferred revenue represents situations where the Company has the contractual right to invoice, or cash is collected, but the related revenue has not yet been recognized. Revenue is subsequently recognized when the revenue recognition criteria are met. Service Revenue is generally invoiced based on pre-defined Costs to Fulfill a Customer Contract The revenue recognition standard requires capitalization of certain costs to fulfil a customer contract, such as certain employee compensation for design and development services that specifically relate to customer contracts. Costs are recognized as an asset if they relate directly to a customer contract, generate or enhance resources of the entity that will be used in satisfying future performance obligations, and are expected to be recovered. If these three criteria are not met, the costs are expensed in the period incurred. Deferred costs are recognized as cost of revenue in the period when the related revenue is recognized. As of January 2, 2022 and December 31, 2020, total deferred contract costs were $4.6 million and $3.5 million, respectively.
Cost of Revenues		Cost of Revenues Cost of revenues includes materials, labor, allocated depreciation expense, and other direct costs related to Service Revenue contracts. Labor consists of personnel-related expenses such as salaries, benefits, and stock-based compensation. Cost of revenue represents costs incurred on certain Service Revenue contracts that was in excess of the amount expected to be recovered.
Research and Development Costs		Research and Development Costs Research and development costs consist of engineering services, allocated facilities costs, depreciation, development expenses, materials, labor and stock-based compensation related primarily to the Company’s (i) technology development, (ii) design, construction, and testing of preproduction prototypes and models, and (iii) certain costs related to the design, construction, and operation of its pilot plant that is not of a scale economically feasible to the Company for commercial production. Research and development costs are expensed as incurred.
Selling, General and Administrative Expenses		Selling, General and Administrative Expenses Selling, general and administrative expenses consist of personnel-related expenses, marketing expenses, allocated facilities expenses, depreciation expenses, executive management travel, and professional services expenses, including legal, human resources, audit, accounting and tax-related
Merger Transaction Costs		Merger Transaction Costs During the fiscal year ended January 2, 2022, the Company incurred significant direct and incremental transaction costs related to the recently completed merger with RSVAC. These transaction costs were first deferred and capitalized to the deferred transaction costs, non-current paid-in
Government Grant		Government Grant In September 2020, the Company entered into a financial assistance agreement totaling $6.5 million with the Office of Energy Efficiency and Renewable Energy (“EERE”), an office within the U.S. Department of Energy. Under the agreement, the Company will perform research and development under a joint project with the EERE, and the EERE will reimbursee the Company for 49.8% of allowable project costs. The remaining 50.2% in costs would be incurred by the Company. The Company accounts for funds which are probable of being received in the same period in which the costs were incurred as an offset to the related expense (Research and development) or capitalized asset (Property and equipment, net). As of January 2, 2022 and December 31, 2020, the Company had a reimbursement receivable from the assistance agreement of $0.3 million and $0.2 million, which is included in Prepaid expenses and other current assets.
Income Taxes		Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes, In addition, ASC 740 provides comprehensive guidance on the recognition and measurement of tax positions in previously filed tax returns or positions expected to be taken in future tax returns. The benefit from an uncertain tax position must meet a more-likely-than-not
Stock-Based Compensation		Stock-Based Compensation The Company issues stock-based compensation to employees and non-employees Restricted Stock Units Starting non-employees Stock options Generally, the stock options have a maximum contractual term up to 10 years. The fair value of stock options is based on the date of the grant using the Black-Scholes valuation method. The awards are accounted for by recognizing the fair value of the related award over the period during which services are provided in exchange for the award (referred to as the requisite service period, which typically equals the vesting period of the award). The vesting period is generally four or five years. No stock awards have been issued with a market condition or other performance vesting condition. In accordance with ASU 2018-07 non-employee Fair Value of Common Stock and Stock Option Prior to the completion of the Business Combination, the fair value of the Company’s common stock underlying stock options was determined by the Company’s board of directors. Given the absence of a public trading market, the board of directors considered numerous objective and subjective factors to determine the fair value of the Company’s common stock at each board of directors meeting in which stock awards were approved. These factors included, but were not limited to: (i) contemporaneous third-party valuations of common stock; (ii) the rights, preferences, and privileges of convertible preferred stock relative to common stock; (iii) the lack of marketability of common stock; (iv) stage and development of the Company’s business; (v) general economic conditions; and (vi) the likelihood of achieving a liquidity event, such as an initial public offering, or sale of the Company, given prevailing market conditions. Based on the valuation reports from the third-party and the relevant factors as discussed above, the Company determined the fair value per share of the underlying common stock of the stock options. The following assumptions are used in the Black-Scholes valuation model for the fair value of stock options per share. • Expected Term — The expected term of the options represents the average period the share options are expected to remain outstanding. As the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior, the expected term of options granted is derived from the average midpoint between the weighted average vesting and the contractual term, also known as the simplified method. The Company uses the simplified calculation of the expected life, which takes into consideration the grant’s contractual life and vesting period and assumes that all options will be exercised between the vesting date and the contractual term of the option. • Risk-Free Interest Rate — The risk-free interest rate is based on the yield of U.S. Treasury notes as of the grant date with terms commensurate with the expected term of the option. • Dividend Yield — The expected dividends assumption is based on the Company’s expectation of not paying dividends in the foreseeable future, as well as the Company did not pay any dividends in the past. • Volatility — Prior to the Business Combination, Legacy Enovix was a private company and did not have any trading history for its ordinary shares, the expected volatility was based on the historical volatilities of the common stock of comparable publicly traded companies that Legacy Enovix selected with comparable characteristics, including enterprise value, risk profiles, position within the industry, and with historical share price information sufficient to meet the expected life of the Legacy Enovix’s stock options.
Net Loss per Share of Common Stock		Net Loss per Share of Common Stock Basic net loss per share of common stock is calculated using the two-class non-forfeitable 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. Unvested early exercised stock options are not considered outstanding for purposes of the weighted average outstanding share calculation until they vest. Diluted earnings per share (“EPS”) attributable to common stockholders adjusts basic EPS for the potentially dilutive impact of the participating securities. As the Company has reported losses for the periods presented, all potentially dilutive securities including convertible preferred stock, stock options and warrants, are generally antidilutive and accordingly, basic net loss per share equals diluted net loss per share, except when there were changes in fair value of the Private Placement Warrants recorded in earnings. With changes in fair value recorded in earnings, an adjustment would be made to both the diluted EPS numerator and denominator to eliminate such effects.

ASU 2019-12 In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . 2016-02 right-of-use . The guidance requires lessees to recognize all leases, with certain exceptions, on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee must recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. On January 1, 2021, the Company early adopted ASU 2016-02 using the modified retrospective transition option of applying the new standard at the adoption date for all leases with terms greater than 12 months. The Company elected certain practical expedients upon adoption and as such did not reassess the following: 1) whether any expired or existing contracts are or contain leases; 2) lease classification for any expired or existing leases; 3) initial direct costs for any expired or existing leases; 4) whether existing or expired land easements are or contain leases; and 5) regarding the lease term, from a hindsight perspective, whether or not the Company is reasonably certain to exercise the lease options. The Company also elected the practical expedient to not separate lease and non-lease components.
