Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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 our accounts, our wholly-owned subsidiaries and majority-owned subsidiaries, the business combinations from the closing dates and a variable interest entity (“VIE”) under the variable interest model. All intercompany balances and transactions have been eliminated in consolidation. Liquidity and Capital Resources We have incurred operating losses and negative cash flows from operations since our inception through June 30, 2024 and expect to incur operating losses for the foreseeable future. As of June 30, 2024, we had working capital of $202.0 million and an accumulated deficit of $761.1 million. In the first half of fiscal year 2024, we received net proceeds of $40.0 million from the issuance of our common stock through an at-the-market (“ATM”) offering. Based on the anticipated spending and timing of expenditures, we currently expect that our cash will be sufficient to meet our funding requirements over the next twelve months. Going forward, we may require additional financing for our future operations and expansion. The accompanying condensed consolidated financial statements have been prepared assuming we 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 These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“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 our financial condition, results of operations, comprehensive income (loss), stockholders’ equity and cash flows for the periods presented above. The results of operations for the quarter and fiscal year-to-date ended June 30, 2024 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 December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date and the accompanying consolidated financial statements and related notes are included in our Annual Report on Form 10-K. 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 and intangible assets, valuation for inventory, valuation allowance on deferred tax assets, assumptions used in income tax provisions, valuation for assets acquired and liabilities assumed in business combination, valuation of goodwill and intangible assets, assumptions used in stock-based compensation, incremental borrowing rate for operating right-of-use assets and lease liabilities, restructuring costs and estimates to fair value common stock warrants. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that it believes to be reasonable under the circumstances. Summary of Significant Accounting Policies There have been no changes to our significant accounting policies disclosed in Note 2 “Summary of Significant Accounting Policies,” of the notes to the consolidated financial statements for the fiscal year ended December 31, 2023, included in Part II, Item 8 of our Form 10-K. Revenue We recognize revenue in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers. We generate revenue from our Product Revenue and Service Revenue for the development of lithium-ion battery technology. Product Revenue Our product revenue is primarily generated from selling lithium-ion batteries or battery packs to commercial customers and military contractors. Product Revenue is recognized once we have satisfied the performance obligations as defined in the sales agreement, which is generally satisfied upon transfer of control of goods. Control is transferred upon delivery for our products. For certain customized products with customer acceptance criteria specified in the sales agreement, the performance obligations is generally satisfied upon our customer’s acceptance. Payment terms can vary depending on the contract and it is generally required within 90 days or less from the delivery date or the acceptance date of our product. The amounts of revenue recognized reflects the consideration for the product sold. For the quarter and fiscal year-to-date ended June 30, 2024, our product revenue were $3.8 million and $9.0 million, respectively. Of our total product revenue for the quarter and fiscal year-to-date ended June 30, 2024, approximately 39% and 41%, respectively, were from South Korea based on the billing location of the customers. For the quarter and fiscal year-to-date ended July 2, 2023, our product revenue were immaterial. Service Revenue Service Revenue contracts generally include the design and development efforts to conform our existing battery technology with customers’ required specifications. Consideration for Service Revenue contracts generally become payable when we meet 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 our 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. There was no service revenue recognized the quarters and fiscal years-to-date ended June 30, 2024 and July 2, 2023 Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of significant segment expenses and other segment items on an annual and interim basis. This ASU will be effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We do not expect to have a material impact of the adoption of this ASU on our financial statement disclosures and plan to adopt it for the fiscal year ended December 29, 2024. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topics 740): Improvements to Income Tax Disclosures, which expanded the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for the annual periods beginning December 15, 2024, with early adoption permitted. We are currently evaluating the potential impact of the adoption of this ASU on our financial statement disclosures.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Combinations	Business Combinations Routejade Acquisition On October 31, 2023, we acquired 95.8% of the outstanding shares of Routejade, Inc. (“Routejade”). The following table summarizes the considerations for the acquisition. Cash paid, net of acquisition-related seller expense $ 15,448 Issuance of Enovix common stock (5,923,521 shares) 52,779 Total purchase consideration 68,227 Less: net assets acquired Net assets acquired, excluding liability assumed for acquisition-related seller expense 56,367 Liability assumed for acquisition-related seller expense (357) Net assets acquired 56,010 Goodwill $ 12,217 This acquisition (the “Routejade Acquisition”) constituted a business acquisition in accordance with FASB Accounting Standards Codification (“ASC”) ( Topic 805 ), Business Combinations (“ASC 805”) for business combinations and, therefore, was accounted for as a business combination using the acquisition method of accounting. The tangible and intangible assets acquired and liabilities assumed were recorded based on their estimated fair values at the acquisition date. The following table summarizes the final purchase price allocation based on the fair values of the assets acquired and liabilities assumed as of the acquisition date (in thousands). Cash, cash equivalents and restricted cash acquired $ 5,481 Accounts and notes receivable, net (1) 1,796 Inventory 12,613 Prepaid expenses and other current assets 1,715 Property and equipment, net 28,579 Intangible assets 41,948 Goodwill 12,217 Other non-current assets 365 Debt assumed (7,426) Deferred revenue (10,568) Liabilities assumed (3,182) Deferred income tax liabilities (12,294) Fair value of net assets acquired 71,244 Less: non-controlling interest (2) (3,017) Total purchase consideration 68,227 Less: Cash, cash equivalents, restricted cash acquired (5,481) Total purchase price, net of cash acquired $ 62,746 (1) The gross amount of the acquired accounts and notes receivable was $1.9 million, of which an immaterial amount is expected to be uncollectible. (2) The fair value of non-controlling interest is measured based on the fair values of net assets acquired at the acquisition date and the price for the equity shares and the portion of ownership not held by the acquirer. Goodwill The excess of the purchase price over the fair value of net assets acquired was recorded to goodwill. Goodwill is primarily attributable to the expected synergies from future expected economic benefits, including integrating electrode coating and battery pack manufacturing. Goodwill from this acquisition is not expected to be deductible for tax purposes. The following table summarizes the change in goodwill (in thousands) during the fiscal year-to-date ended June 30, 2024. Goodwill Balances as of December 31, 2023 $ 12,098 Routejade Acquisition - measurement period adjustments (1) 119 Balances as of June 30, 2024 $ 12,217 (1) Our purchase price allocation was finalized in the first quarter of 2024, which included a net adjustment of $0.1 million to goodwill and immaterial adjustments to other assets. Intangible Assets Intangible assets consist of customer relationships, developed technology and trade names and trademarks. Customer relationships relate to Routejade’s existing customer relationships for current and future business. Developed technology relates to Routejade’s technology for manufacturing standard lithium-ion batteries with varying chemistries, which allows for design flexibility and the production of customized battery cells. The following table summarizes the intangible assets subject to amortization, net (in thousands) as of June 30, 2024.

The condensed consolidated unaudited proforma net income related to this acquisition was not included because the impact on our consolidated results of operations was not material for the quarters and fiscal years-to-date ended June 30, 2024 and July 2, 2023.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement The fair value of our financial assets and liabilities are determined in accordance with the fair value hierarchy established in ASC 820, Fair Value Measurements, issued by the FASB. The fair 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. Our financial instruments consist primarily of cash and cash equivalents, short-term investments, accounts receivable, notes receivable, accounts payable, short-term and long-term debt, and warrant liabilities. Cash and cash equivalents are reported at their respective fair values on our Condensed Consolidated Balance Sheets. As of June 30, 2024 and December 31, 2023, the carrying values of accounts and notes receivables, accounts payable, short-term debt and accrued liabilities approximated the fair value based on the short maturity of those instruments. As of June 30, 2024 and December 31, 2023, we had cash and cash equivalents of $235.1 million and $233.1 million, respectively. The following table details the fair value measurements of assets and liabilities that were measured at fair value on a recurring basis based on the following three-tiered fair value hierarchy per ASC 820, Fair Value Measurement , as of June 30, 2024 and December 31, 2023 (in thousands). Fair Value Measurement using Level 1 Level 2 Level 3 Total As of June 30, 2024 Assets: Cash equivalents: Money Market Funds $ 106,971 $ — $ — $ 106,971 U.S. Treasuries — 32,885 — 32,885 Short-term investments: U.S. Treasuries — 14,826 — 14,826 Liabilities: Private Placement Warrants $ — $ — $ 55,440 $ 55,440 As of December 31, 2023 Assets: Cash equivalents: Money Market Funds $ 19,312 $ — $ — $ 19,312 U.S. Treasuries — 45,175 — 45,175 Short-term investments: U.S. Treasuries — 73,694 — 73,694 Liabilities: Private Placement Warrants $ — $ — $ 42,900 $ 42,900 Cash Equivalents and Short-term Investments: The following is a summary of cash equivalents and short-term investments (in thousands).

Private Placement Warrants Our liabilities are measured at fair value on a recurring basis, including 6,000,000 warrants that were held by Rodgers Capital, LLC (the “Sponsor”) and certain of its members (the “Private Placement Warrants”). The fair value of the Private Placement Warrants is considered a Level 3 valuation and is determined using the Black-Scholes valuation model. Each whole Private Placement Warrant became exercisable for one whole share of our common stock at a price of $11.50 per share on December 5, 2021. As of June 30, 2024 and December 31, 2023, we had 6,000,000 Private Placement Warrants outstanding. The fair value of the Private Placement Warrants was $9.24 per share as of June 30, 2024. The following tables summarize the changes for Level 3 items measured at fair value on a recurring basis using significant unobservable inputs (in thousands). Private Placement Warrants Fair value as of December 31, 2023 $ 42,900 Change in fair value 12,540 Fair value as of June 30, 2024 $ 55,440 Private Placement Warrants Fair value as of January 1, 2023 $ 49,080 Change in fair value 27,180 Fair value as of July 2, 2023 $ 76,260 The following table summarizes the key assumptions used for determining the fair value of the Private Placement warrants.

As of June 30, 2024, the fair value of the convertible senior notes was approximately $206.1 million. As of June 30, 2024, our long-term loans are approximately close to their carrying value of $2.2 million.

Commitments and Contingencies	Commitments and Contingencies Purchase Commitments As of June 30, 2024 and December 31, 2023, our commitments included approximately $34.1 million and $62.5 million, respectively, of our open purchase orders and contractual obligations that occurred in the ordinary course of business, including commitments with contract manufacturers and suppliers for which we have not received goods or services, commitments for capital expenditures and construction-related activities for which we have not received the services. Although open purchase orders are considered enforceable and legally binding, the terms generally allow us an option to cancel, reschedule, and adjust its requirements based on our business needs prior to the delivery of goods or performance of services. For lease obligations, please refer to Note 7 “Leases” for more details. For the Convertible Senior Notes obligation and other borrowings, please refer to Note 8 “Borrowings” for more details. Performance Obligations As of June 30, 2024, we had $10.8 million of performance obligations, which comprised of total deferred revenue and customer order deposits. We currently expect to recognize approximately 65% of deferred revenue as revenue within the next twelve months. Litigation From time to time, we are subject to a variety of claims, lawsuits, investigations, and proceedings concerning matters arising in connection with our business activities, including product liability, intellectual property, commercial, insurance, securities laws, contract disputes, and employment matters. Certain of these lawsuits and claims are described in further detail below. We intend to vigorously defend against each of these allegations. A liability and related charge to earnings is recorded in the condensed consolidated financial statements for legal contingencies when the loss is considered probable and the amount can be reasonably estimated. The assessment is re-evaluated each accounting period and is based on all available information, including the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to each case. The outcomes of outstanding legal matters are inherently unpredictable and subject to uncertainties. While there can be no assurance of favorable outcome of these legal matters, we currently believe that the outcome of these matters will not have a material adverse effect on our results of operations, liquidity or financial position. Former Employee Class Action Lawsuits On January 21, 2022, two former machine operator employees filed a putative wage and hour class action lawsuit against Enovix and co-defendant Legendary Staffing, Inc. in the Superior Court of California, County of Alameda. The case is captioned Sopheak Prak & Ricardo Pimentel v Enovix Corporation and Legendary Staffing, Inc. , 22CV005846 (the “Prak Complaint”). The Prak Complaint alleges, among other things, on a putative class-wide basis, that the defendants failed to pay all overtime wages and committed meal period, rest period and wage statement violations under the California Labor Code and applicable Wage Orders. The plaintiffs are seeking unpaid wages, statutory penalties and interest and reasonable costs and attorney fees. In September 2022, we began the mediation process. On June 6, 2024 a final settlement was approved by the court. The loss liability for the Prak Complaint was recorded on the Condensed Consolidated Balance Sheet as of June 30, 2024 and settlement funds were distributed in July 2024. On March 8, 2023, a former employee filed a putative class action lawsuit against Enovix in the Superior Court of California, County of Alameda. The case is captioned Kody Walker v. Enovix Corporation , 23CV028923 (the “Walker Complaint”). The Walker Complaint alleges, among other things, on a putative class-wide basis, that we failed to pay minimum wages, overtime and sick time wages, failed to reimburse employees for required expenses, failed to provide meal and rest periods and issued inaccurate wage statement under the California Labor Code and applicable Wage Orders. The Walker Complaint asserts on an individual basis that Walker was constructively discharged. The plaintiff seeks unpaid wages, statutory penalties and interest and reasonable costs and attorney fees. While we are unable to predict the likely outcome or the potential cost or duration of this matter, based on the information we currently possess, we do not expect the total potential cost to be material to our financial position. Securities Class Action Complaint On January 6, 2023, a purported Company stockholder filed a securities class action complaint in the U.S. District Court for the Northern District of California against Enovix and certain of our current and former officers and directors (collectively, the “defendants”). The complaint alleges that the defendants violated Sections 10(b) and 20(a) of the Exchange Act of 1934 and Rule 10b-5 promulgated thereunder by making material misstatements or omissions in public statements related to our manufacturing scale-ups and testing of new equipment. A substantially identical complaint was filed on January 25, 2023 by another purported Company stockholder. Following consolidation of the cases and court appointment of two purported Company stockholder lead plaintiffs, a consolidated complaint alleging substantially similar claims, including allegations that the defendants made material misstatements or omissions in public statements related to testing of new equipment, was filed on July 7, 2023. The court granted the motion to dismiss the consolidated complaint on January 30, 2024. The plaintiffs filed a second amended complaint on March 19, 2024, which seeks unspecified damages, interest, fees and costs on behalf of all persons and entities that purchased and/or acquired shares of Enovix or its predecessor entity’s common stock between June 24, 2021 and October 3, 2023. On July 23, 2024, the court issued an order granting in part and denying in part defendants’ motion to dismiss. We and the defendants intend to vigorously defend against the remaining claims in this action. Guarantees and Indemnifications In the normal course of business, we enter into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. In addition, we purchased performance bonds for guarantee of our performance obligations for certain projects. Our exposure under these agreements is unknown because it involves claims that may be made against us in the future but have not yet been made. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations. We also have indemnification obligations to our officers and directors for specified events or occurrences, subject to some limits, while they are serving at our request in such capacities. There have been no claims to date and we have director and officer insurance that may enable us to recover a portion of any amounts paid for future potential claims. We believe the fair value of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities relating to these obligations for the period presented.

Share-Based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation We issue equity awards to our employees and non-employees in the form of stock options, restricted stock units (“RSUs”) and performance based RSUs (“PRSUs”). Additionally, we also offer an employee stock purchase plan (“ESPP”) to our eligible employees. We use Black-Scholes option pricing model to value our stock options granted and the estimated shares to be purchased under the ESPP. For both RSUs and PRSUs, we use our common stock price, which is the last reported sales price on the grant date to value those securities. In general, we recognize stock-based compensation expense on a straight-line basis over the requisite service period and records forfeitures as they occur. For PRSUs, we use the graded vesting method to calculate the stock-based compensation expense. At each reporting period, we would recognize and adjust the stock-based compensation expense based on its probability assessment in meeting its PRSUs' performance conditions. Stock-based Compensation Expense The following table summarizes the total stock-based compensation expense, by operating expense category, recognized in the Condensed Consolidated Statements of Operations for the periods presented below (in thousands). Quarters Ended Fiscal Years-to-Date Ended June 30, 2024 July 2, 2023 June 30, 2024 July 2, 2023 Cost of revenue $ 95 $ 1,654 $ 95 $ 2,605 Research and development 7,303 5,456 13,857 17,123 Selling, general and administrative (1) 10,534 7,932 16,740 24,471 Restructuring cost 1,105 — 1,105 — Total stock-based compensation expense $ 19,037 $ 15,042 $ 31,797 $ 44,199 (1) During the quarter ended June 30, 2024, we engaged a consulting company for its services and issued RSUs in exchange for its services. In connection with this service agreement, we recorded approximately $4.6 million of stock-based compensation expense for the quarter and fiscal year-to-date ended June 30, 2024. For the fiscal years-to-date ended June 30, 2024 and July 2, 2023, we capitalized $1.3 million and $0.7 million, respectively, of stock-based compensation as property and equipment, net on the Condensed Consolidated Balance Sheet. There was no recognized tax benefit related to stock-based compensation for the periods presented. In addition, we accrued an immaterial amount of bonus to be settled in equity awards as accrued compensation on the Condensed Consolidated Balance Sheet as of June 30, 2024. As of June 30, 2024, there was approximately $166.7 million of total unrecognized stock-based compensation expense related to unvested equity awards, which are expected to be recognized over a weighted-average period of 3.3 years. As of June 30, 2024, there was approximately $0.8 million of total unrecognized stock-based compensation related to the ESPP, which is expected to be recognized over a period of 1.4 years. Equity Award Modification In connection with the restructuring plan announced in May 2024, there was one equity award modification, which accelerated the vesting condition of a former executive’s RSUs as a part of his consulting and separation agreement. Accordingly, we recognized $1.1 million of stock-based compensation expense related to the modification for the quarter and fiscal year-to-date ended June 30, 2024, For the quarter ended July 2, 2023, there was no equity award modification. For the fiscal year-to-date ended July 2, 2023, we recognized $21.1 million of stock-based compensation expense related to the modifications in connection with the retirement or resignation of several of our former officers and executives, which impacted the vesting conditions as the term of equity award exercise period was extended and certain of the equity awards were accelerated and vested immediately. Stock Option Activity The following table summarizes stock option activities for the fiscal year-to-date ended June 30, 2024 (in thousands, except share and per share amount).

These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“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 our financial condition, results of operations, comprehensive income (loss), stockholders’ equity and cash flows for the periods presented above. The results of operations for the quarter and fiscal year-to-date ended June 30, 2024 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 December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date and the accompanying consolidated financial statements and related notes are included in our Annual Report on Form 10-K.

All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	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 and intangible assets, valuation for inventory, valuation allowance on deferred tax assets, assumptions used in income tax provisions, valuation for assets acquired and liabilities assumed in business combination, valuation of goodwill and intangible assets, assumptions used in stock-based compensation, incremental borrowing rate for operating right-of-use assets and lease liabilities, restructuring costs and estimates to fair value common stock warrants. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that it believes to be reasonable under the circumstances.
Revenue	We recognize revenue in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers. We generate revenue from our Product Revenue and Service Revenue for the development of lithium-ion battery technology. Product Revenue Our product revenue is primarily generated from selling lithium-ion batteries or battery packs to commercial customers and military contractors. Product Revenue is recognized once we have satisfied the performance obligations as defined in the sales agreement, which is generally satisfied upon transfer of control of goods. Control is transferred upon delivery for our products. For certain customized products with customer acceptance criteria specified in the sales agreement, the performance obligations is generally satisfied upon our customer’s acceptance. Payment terms can vary depending on the contract and it is generally required within 90 days or less from the delivery date or the acceptance date of our product. The amounts of revenue recognized reflects the consideration for the product sold. For the quarter and fiscal year-to-date ended June 30, 2024, our product revenue were $3.8 million and $9.0 million, respectively. Of our total product revenue for the quarter and fiscal year-to-date ended June 30, 2024, approximately 39% and 41%, respectively, were from South Korea based on the billing location of the customers. For the quarter and fiscal year-to-date ended July 2, 2023, our product revenue were immaterial.

This ASU will be effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. We do not expect to have a material impact of the adoption of this ASU on our financial statement disclosures and plan to adopt it for the fiscal year ended December 29, 2024.
