Summary of Significant Accounting Policies	Oct. 01, 2023
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 the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company did not have any income tax expenses for the periods presented. Liquidity and Capital Resources The Company has incurred operating losses and negative cash flows from operations since its inception through October 1, 2023 and expects to incur operating losses for the foreseeable future. As of October 1, 2023, the Company had a working capital of $331.6 million and an accumulated deficit of $538.9 million. In April 2023, we closed private offerings of $172.5 million aggregate principal amount of 3.0% convertible senior notes due 2028 (the “Convertible Senior Notes”). The net proceeds from the Convertible Senior Notes were approximately $166.6 million. The Company used approximately $17.3 million of the net proceeds from the offerings of the Convertible Senior Notes to pay the cost of the capped call transactions entered on April 20, 2023 in connection with such offerings. The Company will use the remaining net proceeds to build out a second battery cell manufacturing facility (“Fab2”) in Malaysia and fund the acquisition of production lines of the Company’s second-generation (“Gen2”) manufacturing equipment (“Gen2 Autolines”), and for working capital and other general corporate purposes. See Note 7 “Borrowings” for more information. Based on the anticipated spending 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 operations and 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 October 1, 2023, the Condensed Consolidated Statements of Operations, the Condensed Consolidated Statement of Comprehensive Income, the Condensed Consolidated Statements of Changes in Shareholders’ Equity and the Condensed Consolidated Statements of Cash Flows for the quarters and fiscal years-to-date ended October 1, 2023 and October 2, 2022 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 and year-to-date ended October 1, 2023 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 1, 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 the Company’s 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, valuation for inventory, the valuation allowance on deferred tax assets, assumptions used in stock-based compensation, incremental borrowing rate for operating right-of-use assets and lease liabilities, 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 Beginning in May 2023, the Company invested in marketable securities from time to time. In addition, during the third quarter of 2023, the Company acquired variable interests in a legal entity, which is considered as a variable interest entity (“VIE”), in connection with building out the Fab2 operations in Malaysia. For the assessment of the Company’s VIE, please refer to Note 13 “Variable Interest Entity” for more details. As a result of these activities, the Company made the following updates to the 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 January 1, 2023, included in the Company’s Annual Report on Form 10-K. Investments The Company’s investments consist of highly liquid fixed-income securities. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its investments as available-for-sale securities as the Company may sell these securities at any time for use in its current operations or for other purposes, including prior to maturity. Investments with original maturities greater than 90 days and remaining maturities of less than one year are normally classified within current assets on the Condensed Consolidated Balance Sheets. In addition, investments with maturities beyond one year at the time of purchase that are highly liquid in nature and represent the investment of cash that is available for current operations are classified as current assets. Unrealized gains and losses on these investments are reported as a separate component of Accumulated other comprehensive loss until the security is sold, the security has matured, or the security has realized. Realized gains and losses on these investments are calculated based on the specific identification method and would be reclassified from Accumulated other comprehensive loss to Other income (expense), net in the Condensed Consolidated Statements of Operations. The Company has designated all investments as available-for-sale and, therefore, the investments are subject to periodic impairment under the available-for-sale debt security impairment model. Available-for-sale debt securities in an unrealized loss position are written down to fair value through a charge to Other income (expense), net in the Condensed Consolidated Statements of Operations if the Company intends to sell the security or it is more likely than not the Company will be required to sell the security before recovery of its amortized cost basis. The Company evaluates the remaining securities to determine what amount of the excess, if any, is caused by expected credit losses. A decline in fair value attributable to expected credit losses is recorded to Other income (expense), net, while any portion of the loss related to non-credit factors is recorded in accumulated other comprehensive income (loss). For securities sold prior to maturity, the cost of the securities sold is based on the specific identification method. Realized gains and losses on the sale of investments are recorded in Other income (expense), net in the Condensed Consolidated Statements of Operations. Variable Interest Entity The Company determines at the inception of each arrangement whether an entity in which the Company holds an investment or in which the Company has other variable interests is considered a VIE. The Company consolidates the VIE’s balance sheet and results of operations into its condensed consolidated financials when the Company deems to be the primary beneficiary that meets both of the following criteria: (1) the Company has the power to direct activities that most significantly affect the VIE’s economic performance and (2) the Company has the obligation to absorb losses or the right to receive benefits of the VIE that in either case could potentially be significant to the VIE. The Company continually reassesses whether the Company is the primary beneficiary of a VIE for the consolidation analysis. If the Company is not the primary beneficiary in a VIE, the Company accounts for the investment or other variable interest in accordance with applicable GAAP. Please refer to Note 13 “Variable Interest Entity” for more details. The Company will reconsider whether the entity is still a VIE if certain reconsideration events occur as defined in the Accounting Standards Codification (“ASC”) 810, Consolidation, issued by the Financial Accounting Standards Board (“FASB”). Foreign Currency Transactions The functional currency of the Company’s international subsidiaries is the U.S. dollar. Monetary assets and liabilities of the Company's international subsidiaries that are denominated in foreign currency are remeasured into U.S. dollars at period-end exchange rates. Non-monetary assets and liabilities that are denominated in the foreign currency are remeasured into U.S. dollars at the historical rates. Foreign transaction gains and losses resulting from the conversion of the transaction currency to functional currency and remeasurement of foreign currency accounts are reflected in Other income (expense), net of the Condensed Consolidated Statements of Operations. For the quarter and fiscal year-to-date ended October 1, 2023, the Company recorded an immaterial amount of net foreign transaction gains in Other income (expense), net of the Condensed Consolidated Statements of Operations.

Fair Value Measurement

Fair Value Disclosures [Abstract]

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, 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.

The Company's financial instruments consist primarily of cash and cash equivalents, short-term investments, accounts receivable, accounts payable and warrant liabilities. Cash and cash equivalents are reported at their respective fair values on the Company's Condensed Consolidated Balance Sheets. 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 October 1, 2023 and January 1, 2023 (in thousands).

Convertible Senior Notes

On April 20, 2023, the Company issued $172.5 million aggregate principal amount of Convertible Senior Notes, pursuant to an indenture, dated as of April 20, 2023 (the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). The offerings and sale of the Convertible Senior Notes were made by the Company to the initial purchasers in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), for resale by the initial purchasers to qualified institutional buyers (as defined in the Securities Act) pursuant to the exemption from registration provided by Rule 144A under the Securities Act. The issuance included the exercise in full by the initial purchasers of their option to purchase an additional $22.5 million aggregate principal amount of the Convertible Senior Notes. $10.0 million principal amount of the Convertible Senior Notes (the “Affiliate Notes”) were issued to an entity affiliated with Thurman John “T.J.” Rodgers, the Company’s Chairman in a concurrent private placement.

The Convertible Senior Notes are unsecured obligations of the Company and bear interest at a rate of 3.0% per year from April 20, 2023, and will be payable semiannually in arrears on May 1 and November 1 of each year, beginning on November 1, 2023. The Convertible Senior Notes will mature on May 1, 2028 unless earlier converted, redeemed or repurchased.

The net proceeds from the offerings were approximately $166.6 million. The Company used approximately $17.3 million of the net proceeds from the offerings to pay the cost of the capped call transactions entered on April 20, 2023 in connection with the offerings. The Company will use the remaining net proceeds to build out Fab2 in Malaysia and fund the acquisition of Gen2 Autolines, and for working capital and other general corporate purposes.

The conversion rate for the Convertible Senior Notes will initially be 64.0800 shares of the Company’s common stock per $1,000 principal amount of the Convertible Senior Notes, which is equivalent to an initial conversion price of $15.61 per share of common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture.

Holders of the Convertible Senior Notes may convert all or any portion of their notes, in integral multiples of $1,000 principal amount, at their option at any time prior to the close of business on the business day immediately preceding February 1, 2028 only under the following conditions:

•during any fiscal quarter commencing after the fiscal quarter ending on October 1, 2023 (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

•during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the “trading price” (as defined in the Indenture) per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

•if the Company calls the Convertible Senior Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Senior Notes called (or deemed called) for redemption; or

•upon the occurrence of specified corporate events as set forth in the Indenture.

On or after February 1, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, at any time, in integral multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing conditions.

Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture.

The Company may not redeem the Convertible Senior Notes prior to May 6, 2026. The Company may redeem for cash all or any portion of the Convertible Senior Notes, at its option, on or after May 6, 2026, if the liquidity condition is satisfied and the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If the Company redeem less than all the outstanding notes, at least $100.0 million aggregate principal amount of notes must be outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant redemption notice.

If the Company undergoes a “fundamental change,” as defined in the Indenture, fundamental change permits the holders of the Convertible Senior Notes to require the Company to repurchase the Convertible Senior Notes, subject to certain terms and conditions as defined in the Indenture. Holders may require the Company to repurchase for cash all or any portion of their notes in principal amounts of $1,000 or an integral multiple thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the Convertible Senior Notes, the Company accounted for the Convertible Senior Notes as liability instruments and considered it as single units of account pursuant to the Accounting Standards Update (“ASU”) No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40), (“ASU 2020-06”). Accrued interest for the Convertible Senior Notes was recorded as Accrued expenses on the Condensed Consolidated Balance Sheet. Costs incurred in connection with the issuance of debt are deferred and amortized as interest expense over the term of the related debt using the effective interest method. To the extent that the debt is outstanding, the debt issuance costs were recorded as a reduction to Long-term debt, net on the Condensed Consolidated Balance Sheet. For the fiscal year-to-date ended October 1, 2023, the Company incurred approximately $5.9 million of debt issuance costs relating to the issuance of the Convertible Senior Notes. There was no debt issuance cost recorded for the quarter ended October 1, 2023.

The following table summarizes the interest expenses related to Convertible Senior Notes, which are recorded within Interest expense in the Condensed Consolidated Statements of Operations (in thousands).


	October 1, 2023
	Quarter Ended		Fiscal Year-to-Date Ended
Coupon interest	$	1,283	$	2,326
Amortization of debt issuance costs	275		497
Total interest expense on Convertible Senior Notes	$	1,558	$	2,823

As of October 1, 2023, the Company had $2.3 million of accrued interest liability. There was no accrued interest liability as of January 1, 2023.

Capped Call Transactions

In connection with the issuance of the Convertible Senior Notes, the Company paid approximately $17.3 million to enter into capped call transactions with certain financial institutions (the “Capped Calls”) in the second quarter of 2023. The Capped Calls are generally expected to reduce the potential dilution to the Company's common stock upon any conversion of the Convertible Senior Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted Convertible Senior Notes, as the case may be, with such reduction and/or offset subject to a cap based on a cap price initially equal to $21.17 per share (which represents a premium of 56.0% over the last reported sale price of the Company's common stock of $13.57 per share on The Nasdaq Global Select Market on April 17, 2023), and is subject to certain adjustments under the terms of the Capped Calls. The Company recorded the Capped Calls

as a reduction of stockholders' equity, not as derivatives, as the Capped Calls met certain accounting criteria. No subsequent remeasurement is required.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Commitments As of October 1, 2023 and January 1, 2023, the Company’s commitments included approximately $73.7 million and $22.7 million, respectively, of the Company’s open purchase orders and contractual obligations that occurred in the ordinary course of business, including commitments with contract manufacturers and suppliers for which the Company has not received the goods or services, commitments for capital expenditures and construction-related activities for which the Company has not received the services. Although open purchase orders are considered enforceable and legally binding, the terms generally allow the Company the option to cancel, reschedule, and adjust its requirements based on its business needs prior to the delivery of goods or performance of services. For lease obligations, please refer to Note 6 “Leases” for more details. For the Convertible Senior Notes obligation, please refer to Note 7 “Borrowings” for more details. Performance Obligations As of October 1, 2023, the Company had $3.8 million of performance obligations, which comprised of total deferred revenue and customer order deposits. Currently, the Company does not expect to recognize revenue from deferred revenue within the next twelve months. Litigation From time to time, the Company is involved in a variety of claims, lawsuits, investigations, and proceedings relating to securities laws, product liability, intellectual property, commercial, insurance, contract disputes, employment, and other matters. Certain of these lawsuits and claims are described in further detail below. The Company intends to defend vigorously against all of the following allegations. A liability and related charge to earnings are 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 the Company’s results of operations, liquidity or financial position. Sopheap Prak et al. v. Enovix Corporation et al., 22CV005846, Superior Court of California, Alameda County 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 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, the Company began the mediation process. Based on the current knowledge of the legal proceeding, an estimate of possible loss liability was recorded on the Condensed Consolidated Balance Sheet as of October 1, 2023. Kody Walker v. Enovix Corporation, 23CV028923. Superior Court of California, Alameda County 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 “Walker Complaint”). The Walker Complaint alleges, among other things, on a putative class-wide basis, that the Company 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. Securities Class Action Compliant 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 the Company and certain of its current and former officers and directors. The complaint alleges that 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 the Company’s manufacturing scaleups 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 consolidated complaint seeks unspecified damages, interest, fees and costs on behalf of all persons and entities who purchased and/or acquired shares of the Company or RSVAC’s common stock between June 24, 2021 and January 3, 2023. The Company and the named officers and directors moved to dismiss the complaint on September 15, 2023. Based on currently available information, the Company is unable to make a reasonable estimate of loss or range of losses, if any, arising from this matter. Guarantees and Indemnifications In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations. The Company also has indemnification obligations to its officers and directors for specified events or occurrences, subject to some limits, while they are serving at the Company’s request in such capacities. The Company believes the fair value of these indemnification agreements is minimal. Accordingly, the Company has not recorded any liabilities relating to these obligations for the period presented.

Stock-based Compensation

9 Months Ended

Oct. 01, 2023

Share-Based Payment Arrangement [Abstract]

Stock-based Compensation

Stock-based CompensationThe Company issues equity awards to employees and non-employees in the form of stock options, restricted stock units (“RSUs”) and performance based RSUs (“PRSUs”). Additionally, the Company also offers an employee stock purchase plan (“ESPP”) to its eligible employees. The Company uses Black-Scholes option pricing model to value its stock

options granted and the estimated shares to be purchased under the ESPP. For both RSUs and PRSUs, the Company uses its common stock price, which is the last reported sales price on the grant date to value those securities.

In general, the Company recognizes its stock-based compensation expense on a straight-line basis over the requisite service period and records forfeitures as they occur. For PRSUs, the Company uses the graded vesting method to calculate the stock-based compensation expense. At each reporting period, the Company would recognize and adjust the stock-based compensation expense based on its probability assessment in meeting its PRSUs' performance conditions.

Stock-based Compensation Expense


	Quarters Ended				Fiscal Years-to-Date Ended
	October 1, 2023		October 2, 2022		October 1, 2023		October 2, 2022
Cost of revenue	$	2,396	$	1,067	$	5,001	$	1,317
Research and development	4,949		3,372		22,072		9,705

Restructuring cost	359		—		359		—
Total stock-based compensation expense	$	13,633	$	8,699	$	57,832	$	22,117

For the fiscal years-to-date ended October 1, 2023 and October 2, 2022, the Company capitalized $0.8 million and $1.2 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, the Company accrued an immaterial amount of bonus to be settled in equity awards as accrued compensation on the Condensed Consolidated Balance Sheet as of October 1, 2023.

As of October 1, 2023, there was approximately $140.1 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 3.9 years. As of October 1, 2023, there was approximately $0.5 million of total unrecognized stock-based compensation related to the ESPP, which is expected to be recognized over a period of 1.1 years.

Equity Award Modification

For the first quarter of 2023, in connection with the retirement or resignation of several of the Company's management team members, including the Company's former Chief Executive Officer, the Company evaluated the change in employment status in accordance with ASC 718, Compensation - Stock Compensation. The Company concluded that the change in status 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. For the quarter ended October 1, 2023, there was no equity award modification. For the fiscal year-to-date ended October 1, 2023, the Company recognized $21.1 million of stock-based compensation expense related to the modifications. There is no equity modification occurred for the corresponding period last year.

Stock Option Activity

The following table summarizes stock option activities for the fiscal year-to-date ended October 1, 2023 (in thousands, except share and per share amount).


	Number of Options Outstanding	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (1) (2)
Balances as of January 1, 2023	5,034,282	$	9.07

Exercised	(1,135,249)	8.13			$	13,446
Forfeited	(823,895)	9.20
Balances as of October 1, 2023	3,075,138	$	9.39	7.5	$	11,166


(1)			The intrinsic value of options exercised is based upon the value of the Company’s stock at exercise.
(2)			The aggregate intrinsic value of the stock options outstanding as of October 1, 2023 represents the value of the Company’s closing stock price at $12.55 on the last trading day of the quarter ended October 1, 2023 in excess of the exercise price multiplied by the number of options outstanding.

Unvested early exercised stock options which are subject to repurchase by the Company are not considered participating securities as those shares do not have non-forfeitable rights to dividends or dividend equivalents. Unvested early exercised stock options are not considered outstanding for purposes of the weighted average outstanding share calculation until they vest.

As of October 1, 2023, 657,981 shares remained subject to the Company’s right of repurchase as a result of early exercised stock options. The remaining liability related to early exercised shares as of October 1, 2023 was immaterial and was recorded in other current and non-current liabilities in the Condensed Consolidated Balance Sheets.

Issuance of Common Stock Subject to Return

In connection with certain early exercised stock options, during the quarter ended October 1, 2023, the Company’s transfer agent erroneously issued an additional 1.3 million shares of common stock to several former executive officers as a result of an administrative issue. Based on the Company’s review and assessment as of October 1, 2023, the Company’s loss associated with this common stock issuance was approximately $22.4 million. Currently, the Company expects a full recovery of these common stock shares from the former executive officers. Both the issuance of these shares related to the loss and the corresponding receivable from the probable recovery were recorded as additional paid-in capital on the Condensed Consolidated Balance Sheet as of October 1, 2023. The loss amount and the offsetting probable recovery amount resulted in no impact to the Condensed Consolidated Statement of Operations for the quarter and fiscal year-to-date ended October 1, 2023. This estimate is based on the current known information available, which it is possible to change in the future.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Oct. 01, 2023
Accounting Policies [Abstract]
Basis of presentation	The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”).The Condensed Consolidated Balance Sheet as of October 1, 2023, the Condensed Consolidated Statements of Operations, the Condensed Consolidated Statement of Comprehensive Income, the Condensed Consolidated Statements of Changes in Shareholders’ Equity and the Condensed Consolidated Statements of Cash Flows for the quarters and fiscal years-to-date ended October 1, 2023 and October 2, 2022 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 and year-to-date ended October 1, 2023 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 1, 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 the Company’s Annual Report on Form 10-K.
Consolidation	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. 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, valuation for inventory, the valuation allowance on deferred tax assets, assumptions used in stock-based compensation, incremental borrowing rate for operating right-of-use assets and lease liabilities, 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.
Investments	Investments The Company’s investments consist of highly liquid fixed-income securities. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its investments as available-for-sale securities as the Company may sell these securities at any time for use in its current operations or for other purposes, including prior to maturity. Investments with original maturities greater than 90 days and remaining maturities of less than one year are normally classified within current assets on the Condensed Consolidated Balance Sheets. In addition, investments with maturities beyond one year at the time of purchase that are highly liquid in nature and represent the investment of cash that is available for current operations are classified as current assets. Unrealized gains and losses on these investments are reported as a separate component of Accumulated other comprehensive loss until the security is sold, the security has matured, or the security has realized. Realized gains and losses on these investments are calculated based on the specific identification method and would be reclassified from Accumulated other comprehensive loss to Other income (expense), net in the Condensed Consolidated Statements of Operations. The Company has designated all investments as available-for-sale and, therefore, the investments are subject to periodic impairment under the available-for-sale debt security impairment model. Available-for-sale debt securities in an unrealized loss position are written down to fair value through a charge to Other income (expense), net in the Condensed Consolidated Statements of Operations if the Company intends to sell the security or it is more likely than not the Company will be required to sell the security before recovery of its amortized cost basis. The Company evaluates the remaining securities to determine what amount of the excess, if any, is caused by expected credit losses. A decline in fair value attributable to expected credit losses is recorded to Other income (expense), net, while any portion of the loss related to non-credit factors is recorded in accumulated other comprehensive income (loss). For securities sold prior to maturity, the cost of the securities sold is based on the specific identification method. Realized gains and losses on the sale of investments are recorded in Other income (expense), net in the Condensed Consolidated Statements of Operations.
Variable Interest Entity	Variable Interest Entity The Company determines at the inception of each arrangement whether an entity in which the Company holds an investment or in which the Company has other variable interests is considered a VIE. The Company consolidates the VIE’s balance sheet and results of operations into its condensed consolidated financials when the Company deems to be the primary beneficiary that meets both of the following criteria: (1) the Company has the power to direct activities that most significantly affect the VIE’s economic performance and (2) the Company has the obligation to absorb losses or the right to receive benefits of the VIE that in either case could potentially be significant to the VIE. The Company continually reassesses whether the Company is the primary beneficiary of a VIE for the consolidation analysis. If the Company is not the primary beneficiary in a VIE, the Company accounts for the investment or other variable interest in accordance with applicable GAAP. Please refer to Note 13 “Variable Interest Entity” for more details. The Company will reconsider whether the entity is still a VIE if certain reconsideration events occur as defined in the Accounting Standards Codification (“ASC”) 810, Consolidation, issued by the Financial Accounting Standards Board (“FASB”).
Foreign Currency Transactions	Foreign Currency Transactions The functional currency of the Company’s international subsidiaries is the U.S. dollar. Monetary assets and liabilities of the Company's international subsidiaries that are denominated in foreign currency are remeasured into U.S. dollars at period-end exchange rates. Non-monetary assets and liabilities that are denominated in the foreign currency are remeasured into U.S. dollars at the historical rates. Foreign transaction gains and losses resulting from the conversion of the transaction currency to functional currency and remeasurement of foreign currency accounts are reflected in Other income (expense), net of the Condensed Consolidated Statements of Operations. For the quarter and fiscal year-to-date ended October 1, 2023, the Company recorded an immaterial amount of net foreign transaction gains in Other income (expense), net of the Condensed Consolidated Statements of Operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entity	Variable Interest Entity YBS Agreement On July 26, 2023, the Company entered into a manufacturing agreement (the “Agreement”) with YBS International Berhad (“YBS”), a Malaysia-based investment holding company with segments including electronic manufacturing and assembly, high-precision engineering, precision machining and stamping, among others. The Company and YBS agreed to share an initial investment of $100.0 million for the Gen2 Autoline 1 equipment and facilitation costs, as set out in the Agreement. Pursuant to the terms of the Agreement, the Company shall contribute 30% of the initial investment and YBS has the obligation to finance the remaining 70%. YBS assigned Orifast Solution Sdn Bhd (“OSSB”), a subsidiary, to manufacture lithium-ion batteries for Enovix under the terms and conditions of the Agreement. OSSB obtained $70.0 million of foreign currency term loan (the “Term Loan”) in financing for manufacturing operations under the Agreement from OCBC Bank (Malaysia) Berhad (“OCBC”). The Term Loan is expected to be repaid within six years with a 12 months grace period. Pricing under the Agreement is set on a cost-plus basis and the Company is subject to a minimum commitment pursuant to the Agreement. At any time during the first seven years of the Agreement’s term, the Company reserves the right to purchase the Gen2 Autoline 1 by repaying the equipment cost, net of depreciation, as defined in the Agreement. The Company also bears the early repayment penalty fee imposed by OCBC, if any. The term of the Agreement is for ten years and automatically extends for an additional five years. On September 13, 2023, the Company entered into a cash deposit agreement with OCBC to collateralize the Term Loan and the deposit will be placed in an interest-bearing account with an interest rate on par with the loan rate of the Term Loan. The Company will deposit sufficient collateral for the Term Loan. As of October 1, 2023, there is no outstanding balance of the Term Loan and no deposit was made to OCBC for the collateralization. Consolidated Variable Interest Entity The Company consolidates a VIE when it has the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits of the VIE, which could potentially be significant to the VIE, and, as a result, is considered the primary beneficiary of the VIE. As of October 1, 2023, the Company concluded that OSSB is considered a VIE and the Company is the primary beneficiary of OSSB based on certain assumptions and judgments made by the Company. As of October 1, 2023, the Company did not have an equity investment in OSSB. In accordance with GAAP, the Company consolidates 100% of OSSB financials. During the quarter ended and fiscal year-to-date ended October 1, 2023, OSSB had immaterial operating activities.
