Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”) filed with the SEC on February 28, 2024. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses, and related disclosures. The significant estimates made by management include inventory reserves, useful life of long-lived assets, valuation allowance for deferred tax assets, valuation of warrants issued in a private placement (“Private Warrants”), valuation of contingent consideration payable, and assets acquired in mergers and acquisitions including intangible assets, forecasted costs associated with non-recurring engineering (“NRE”) services, restructuring costs, valuation of convertible and senior notes and derivatives associated with them, valuation of distinct goods and services in the purchase contract with customers and stock-based compensation expense. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates. Derivative Liability The Company evaluated convertible and senior notes to determine if embedded features of those contracts qualify as derivatives to be separately accounted for under the relevant sections of Accounting Standards Codification ("ASC") 815-40, Derivatives and Hedging: Contracts in Entity’s Own Equity. This accounting treatment requires that the carrying amount of any derivatives be recorded at fair value in the consolidated balance sheet at issuance and marked-to-market at each balance sheet date as components of convertible and senior notes. The change in the fair value during the period is recorded in the consolidated statement of operations as either other income or expense as changes in fair value of derivative liability. Upon conversion, exercise or repayment, the respective derivative liability is marked to fair value at the conversion, repayment, or exercise date and then the related fair value amount is reclassified to other income or expense as part of gain or loss on debt extinguishment in the consolidated statement of operations. Segment Information The Company has determined its operating segments using the same indicators which were used to evaluate its performance internally. The Company’s business activities are organized in two operating segments: (i) “Autonomy Solutions” which includes manufacturing and distribution of LiDAR sensors that measure distance using laser light to generate a 3D map, non-recurring engineering services related to the Company’s LiDAR products, development of software products that enable autonomy capabilities for automotive applications, and licensing of certain information. In June 2022, the Company acquired certain assets from Solfice Research, Inc. (“Solfice” or “Civil Maps”). In January 2023, the Company acquired certain assets from Seagate Technology LLC and Seagate Singapore International Headquarters Pte. Ltd. (individually and collectively, “Seagate”). Assets purchased from both Civil Maps and Seagate have been included in the Autonomy Solutions segment. (ii) “Advanced Technologies and Services (“ATS”) which includes the design, development, manufacturing, packaging and development services of photonic components and subsystems (including semiconductor lasers and photodetectors), application-specific integrated circuits and pixel-based sensors. The Company acquired Optogration, Inc. (“Optogration”) in August 2021, Freedom Photonics LLC (“Freedom Photonics”) in April 2022, and EM4, LLC (“EM4”) in March 2024. Operations of Optogration, Freedom Photonics and EM4 have been included in the ATS segment since their respective acquisition dates. Concentration of Credit Risk The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, debt securities and accounts receivable. The Company’s deposits exceed federally insured limits. Cash held by foreign subsidiaries of the Company as of September 30, 2024 and December 31, 2023 was not material. The Company’s revenue is derived from customers located in the United States and international markets. One customer accounted for 39% of the Company’s accounts receivable as of September 30, 2024. One customer accounted for 71% of the Company’s accounts receivable as of December 31, 2023. Significant Accounting Policies The Company’s significant accounting policies are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2023. Changes to the Company’s significant accounting policies during the nine months ended September 30, 2024 in respect to derivative liabilities are disclosed above.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Combinations and Acquisitions	Business Combinations and Acquisitions Acquisition of EM4 On March 18, 2024 (the “Acquisition Date”), the Company completed its acquisition of EM4, a designer, manufacturer and seller of packaged photonic components and sub-systems for aerospace and industrial markets. The EM4 acquisition is expected to accelerate the Company’s strategy to package lasers, detectors and ASICs. The Company acquired 100% of the membership interests of EM4 from G&H Investment Holding, Inc. (“G&H”), for an aggregate purchase price of approximately $4.5 million in cash, net of working capital adjustments, and up to $6.75 million in contingent future payments to G&H subject to the achievement of certain financial performance targets. The fair value of the contingent consideration at the Acquisition Date was estimated to be $0.1 million. The Company utilized a Monte Carlo simulation model to estimate the probability-weighted fair value of the contingent consideration. This transaction has been accounted for as a business combination. The acquisition related costs incurred as part of the transaction were not material. Recording of Assets Acquired and Liabilities Assumed Price allocation includes preliminary estimates of deferred tax balances, certain tax liabilities, for which the Company is in the process of collecting documentation to ascertain potential amounts, and fair value of certain working capital components. Preliminary estimates of fair values included in the condensed consolidated financial statements are expected to be finalized within a one-year measurement period following the acquisition date after which any subsequent adjustments will be reflected in the consolidated statements of operations. The following table summarizes the preliminary purchase price allocation to assets acquired (in thousands): Preliminary Recorded Value Cash and cash equivalents $ 557 Accounts receivable 1,064 Contract asset 1,644 Inventories, net 3,539 Prepaid expenses and other current assets 252 Property plant and equipment 1,888 Operating lease right-of-use assets 2,072 Total assets acquired 11,016 Current liabilities (3,148) Operating lease liabilities, non-current (1,628) Total liabilities assumed (4,776) Net assets acquired $ 6,240 Since the consideration paid by the Company to acquire EM4’s business was lower than the estimated fair value of net assets acquired, the Company recognized a $1.8 million gain from the acquisition of EM4. The following factors contributed towards the purchase price paid by the Company being lower than the estimated fair value of the net assets acquired: (a) EM4 had historically been incurring losses; (b) G&H viewed EM4 as non-core; (c) although G&H pursued a competitive auction process for the business, the ultimate timeline to completion was drawn-out due to the complexity of the transaction structure; and (d) during the later stages of the sale process, after the Company was selected as the winning bidder, EM4’s business was impacted by the cancellation of certain material government programs as well as delays in certain other purchase orders, which also served to significantly reduce the estimated probability of the contingent future payments to G&H. The results of operations related to EM4 are included in our condensed consolidated statements of operations beginning from the Acquisition Date.

The Volvo Warrants vest and become exercisable in two tranches based on satisfaction of certain commercial milestones. The fair value of the first tranche of the Volvo Warrants was recorded as a reduction in revenue in 2021. The second tranche of the Volvo warrants will be recorded as reduction in revenue to be amortized over sales of a certain number of the Company’s sensors to Volvo for use in their commercial vehicles, which commenced in the second quarter of 2024. Contract assets and liabilities Changes in the Company’s contract assets and contract liabilities primarily result from the timing difference between the Company’s performance and the customer’s payment based on contractual terms. Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. Contract liabilities consist of the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration from the customer. Customer advance payments represent required customer payments in advance of product shipments. Customer advance payments are recognized in revenue as or when control of the performance obligation is transferred to the customer.

The Company continually evaluates opportunities for optimizing its manufacturing processes and product design. In 2023, the Company finalized and committed to a plan to change its sourcing of certain sub-assemblies and components from one supplier to another, which requires the Company to abandon certain equipment located at the legacy supplier. As a result, the Company has reduced the useful lives of the long-lived assets within the impacted asset group in line with when these assets are expected to be abandoned. The Company expects the transition to the new supplier to be essentially completed in 2024. The reduction in the estimated useful lives of the impacted assets resulted in the Company recording $0.9 million and $4.4 million of incremental accelerated depreciation charges in the three and nine months ended September 30, 2024, respectively.

These impairment charges were due to events that occurred during the fourth quarter of 2023, including a decision to delay development activities on certain new products resulting from an increasing focus on supporting the product roadmap of the Autonomy Solutions segment, and a lowering of the growth outlook for the business due to less than anticipated traction in sales of new products. During the third quarter of 2024 the Company recognized additional impairment charges of $3.4 million and $3.3 million related to goodwill and IPR&D, related to Freedom Photonics driven by a slower industry lidar adoption rate in the near-term as well as a reduction in the Freedom Photonics workforce assigned to perform development work for external customers. Total life-to-date goodwill impairment charge recorded by the ATS reportable segment was $15.9 million and no impairment charge has been recorded by the Autonomy Solutions reportable segment. In relation to the goodwill, the Company engaged third-party valuation specialists and used industry accepted valuation models and criteria that were reviewed and approved by various levels of management. The Company assessed the fair value of the Freedom Photonics reporting during the fourth quarter of 2023 and the third quarter of 2024, using the discounted cash flow method under the income approach, utilizing estimated cash flows and a terminal value, discounted at a rate of return that reflects the relative risk of the cash flows. The significant assumptions used in the assessment of the reporting unit included revenue growth rates, profit margins, operating expenses, capital expenditures, terminal value and a discount rate. As a result of this assessment, the Company determined in the fourth quarter of 2023 that the carrying value of the Freedom Photonics reporting unit exceeded its estimated fair value by $12.5 million. This resulted in an impairment charge to goodwill, with the remaining goodwill associated with Freedom Photonics being fully impaired in the third quarter of 2024.

The estimated contract losses were primarily driven by delays in achievement of certain milestones and changes in scope of project deliverables agreed upon with a customer.

Debt Disclosure [Abstract]
Debt	Debt 2026 Convertible Senior Notes and Capped Call Transactions In December 2021, the Company issued $625.0 million aggregate principal amount of 1.25% Convertible Senior Notes due 2026 in a private placement, which included $75.0 million aggregate principal amount of such notes pursuant to the exercise in full of the option granted to the initial purchasers to purchase additional notes (collectively, the “2026 Convertible Senior Notes”). The interest on the 2026 Convertible Senior Notes is payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2022. The 2026 Convertible Senior Notes will mature on December 15, 2026, unless repurchased or redeemed earlier by the Company or converted pursuant to their terms. The total net proceeds from the debt offering, after deducting fees paid to the initial purchasers paid by the Company, was approximately $609.4 million. Each $1,000 principal amount of the 2026 Convertible Senior Notes is initially convertible into 50.0475 shares of the Company’s Class A common stock, par value $0.0001, which is equivalent to an initial conversion price of approximately $19.98 per share. The conversion rate is subject to adjustment upon the occurrence of certain specified events prior to the maturity date but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date or if the Company delivers a notice of redemption in respect of some or all of the 2026 Convertible Senior Notes, the Company will, under certain circumstances, increase the conversion rate of the 2026 Convertible Senior Notes for a holder who elects to convert its 2026 Convertible Senior Notes in connection with such a corporate event or convert its 2026 Convertible Senior Notes called for redemption during the related redemption period, as the case may be. The 2026 Convertible Senior Notes are redeemable, in whole or in part (subject to certain limitations), at the Company’s option at any time, and from time to time, on or after December 20, 2024, and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2026 Convertible Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if certain liquidity conditions are satisfied and the last reported sale price per share of the Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice, and (2) the trading day immediately before the date the Company sends such notice. If the Company undergoes a fundamental change (as defined in the indenture governing the 2026 Convertible Senior Notes) prior to the maturity date, holders may require the Company to repurchase for cash all or any portion of their 2026 Convertible Senior Notes in principal amounts of $1,000 or a multiple thereof at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Convertible Senior Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. Holders of the 2026 Convertible Senior Notes may convert their 2026 Convertible Senior Notes at their option at any time prior to the close of business on the business day immediately preceding December 15, 2026, in multiples of $1,000 principal amount, only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on March 31, 2022, if the last reported sale price per share of the Class A common stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of 2026 Convertible Senior Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Class A common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of specified corporate events or distributions on the Class A common stock; and (4) if the 2026 Convertible Senior Notes are called for redemption. On or after June 15, 2026, holders may convert all or any portion of their 2026 Convertible Senior Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its Class A common stock or a combination of cash and shares of its Class A common stock, at the Company’s election. As of September 30, 2024, the conditions allowing holders of the 2026 Convertible Senior Notes to convert were not met. The 2026 Convertible Senior Notes are senior unsecured obligations and will rank equal in right of payment with the Company’s future senior unsecured indebtedness; senior in right of payment to the Company’s future indebtedness that is expressly subordinated to the 2026 Convertible Senior Notes; effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries. The Company has classified the 2026 Convertible Senior Notes as a non-current liability. Debt discount and issuance costs aggregating approximately $16.2 million were initially recorded as a reduction to the principal amount of the 2026 Convertible Senior Notes and is being amortized as interest expense on a straight line basis over the contractual terms of the notes. The Company estimates that the difference between amortizing the debt discounts and the issuance costs using the straight line method as compared to using the effective interest rate method is immaterial. In connection with the offering of the 2026 Convertible Senior Notes, the Company entered into privately negotiated capped call option transactions with certain counterparties (the “Capped Calls”). The Capped Calls each have an initial strike price of approximately $19.98 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2026 Convertible Senior Notes. The Capped Calls have initial cap prices of $30.16 per share, subject to certain adjustment events. The Capped Calls are generally intended to reduce the potential dilution to the Class A common stock upon any conversion of the 2026 Convertible Senior Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2026 Convertible Senior Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. The Capped Calls expire on April 6, 2027, subject to earlier exercise. The Capped Calls are subject to either adjustment or termination upon the occurrence of specified extraordinary events affecting the Company, including a merger event, a tender offer, and a nationalization, insolvency or delisting involving the Company. In addition, the Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including changes in law, failure to deliver, and hedging disruptions. The Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives. The net cost of $73.4 million incurred to purchase the Capped Calls was recorded as a reduction to additional paid-in capital in the accompanying consolidated balance sheet. On August 8, 2024, pursuant to a privately negotiated exchange agreement, the Company exchanged $421.9 million aggregate principal amount of the outstanding 2026 Convertible Senior Notes for $82.3 million aggregate principal amount of its newly issued 9.0% convertible second lien senior secured notes due 2030 (the “Series 1 Notes”), and $192.0 million aggregate principal amount of its newly issued 11.5% convertible second lien senior secured notes due 2030 (the “Series 2 Notes”, and collectively with the Series 1 Notes, the “2030 Convertible Notes”). Concurrently with the exchange transaction, the Company also issued $100.0 million aggregate principal amount of its newly issued first-lien, senior secured floating rate notes due 2028 (the “Senior Notes”) in a private placement for cash consideration of $97.0 million. As a result of the exchange and purchase transactions, during the third quarter of 2024, the Company recognized $142.2 million gain on debt extinguishment which represented the difference between the carrying value of the 2026 Convertible Senior Notes so exchanged and the collective fair value of 2030 Convertible Notes and the Senior Notes, net of the cash payment received from the investors. The extinguishment gain was recorded in Other income, net in the condensed consolidated statements of operations. The net carrying amount of the 2026 Convertible Senior Notes was as follows (in thousands): September 30, 2024 December 31, 2023 Principal $ 203,083 $ 625,000 Unamortized debt discount and issuance costs (2,326) (9,572) Net carrying amount $ 200,757 $ 615,428 The following table sets forth the interest expense recognized related to the 2026 Convertible Senior Notes (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Contractual interest expense $ 1,189 $ 1,969 $ 5,084 $ 5,843 Amortization of debt discount and issuance costs 481 809 2,099 2,427 Total interest expense $ 1,670 $ 2,778 $ 7,183 $ 8,270 The remaining term over which the debt discount and issuance costs will be amortized is 2.2 years. Senior Notes On August 8, 2024, the Company issued $100.0 million aggregate principal amount of Senior Notes in a private placement. At the time of the issuance, the fair value of the Senior Notes is $97.0 million, resulting in a debt discount of $3.0 million. The Senior Notes will mature on the earlier of (i) August 15, 2028 or (ii) if more than $100.0 million of the 2026 Convertible Senior Notes remain outstanding as of June 30, 2026, then September 15, 2026. The Senior Notes will bear floating interest at a rate equal to Term SOFR plus 9.0%, subject to a Term SOFR floor of 3.0%, resulting in an effective interest rate of 14.1% as of September 30, 2024. Interest is payable quarterly in arrears on February 15, May 15, August 15, and November 15 of each year. The Company may redeem the Senior Notes at its option, in whole at any time or in part from time to time, at the following redemption prices (expressed as percentages of principal amount) plus accrued and unpaid interest, if redeemed during the following periods, inclusive of the prepayment fee due on any such redemption: on or prior to August 15, 2026: 111%; after August 15, 2026 and on or prior to August 15, 2027: 108%; and after August 15, 2027: 103%. The Senior Notes are also subject to a customary make whole payment in the event of any redemption or acceleration of the Senior Notes on or prior to August 15, 2025. In the event of a change of control, as defined in the indenture governing the Senior Notes (the “First Lien Indenture”), the holders of the Senior Notes may require the Company to repurchase their notes at a cash repurchase price equal to 103% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. The Senior Notes are guaranteed by certain of the Company’s current and future material subsidiaries on a senior secured basis, subject to certain criteria and exceptions. The Senior Notes and the guarantees are secured by a fully perfected first-priority lien on substantially all of the assets of the Company and the Guarantors, subject to certain exceptions, including any first-priority liens on customary asset-based lending collateral, including accounts receivable and inventory, pursuant to a revolving credit facility permitted under the First Lien Indenture. The First Lien Indenture includes restrictive covenants that, among other things, limit the ability of the Company and its subsidiaries to incur additional debt, make restricted payments and grant or incur liens, in addition to a financial covenant to maintain an unrestricted cash and cash equivalents balance, plus any unused commitments then available to be drawn under any revolving credit facility permitted under the First Lien Indenture, of not less than $35.0 million as of the last day, or for more than five days, of any calendar month. The First Lien Indenture also contains customary events of default. The Company has classified the Senior Notes as a non-current liability. Initial debt discount and issuance costs aggregating approximately $4.9 million were initially recorded as a reduction to the principal amount and will be amortized as interest expense over the contractual terms of the Senior Notes based on the effective interest rate of 16.0%. The Company recognized interest expense of $2.2 million for the Senior Notes during the three and nine months ended September 30, 2024, which included $0.1 million from the amortization of debt discount and issuance costs. The net carrying amount of the Senior Notes was as follows (in thousands): September 30, 2024 Principal $ 100,000 Unamortized debt discount and issuance costs (4,728) Net carrying amount $ 95,272 The remaining term over which the debt discount and issuance costs will be amortized is 3.9 years. The Company estimated the fair value of the Senior Notes using a binomial model as of August 8, 2024, with the following valuation inputs: payment interest rate of 12.4% - 14.3%, effective borrowing rate of 14.4%, interest rate volatility of 23.0%. The Company estimated the fair value of the Senior Notes using a binomial model as of September 30, 2024, with the following valuation inputs: payment interest rate of 12.0% - 13.1%, effective borrowing rate of 9.7%, interest rate volatility of 23.0%. 2030 Convertible Notes On August 8, 2024, the Company issued $82.3 million aggregate principal amount of the Series 1 Notes and $192.0 million aggregate principal amount of the Series 2 Notes in exchange for $421.9 million aggregate principal amount of outstanding 2026 Convertible Senior Notes. At the time of the exchange, the fair value of the Series 1 Notes and the Series 2 Notes is $87.5 million and $186.2 million, resulting in a debt premium of $5.2 million and a debt discount of $5.7 million, respectively. The 2030 Convertible Notes will mature on the earlier of (i) January 15, 2030 or (ii) if more than $100.0 million of the 2026 Convertible Senior Notes remain outstanding as of June 30, 2026, then September 15, 2026. The Series 1 Notes bear interest at a rate of 9.0% per annum, and the Series 2 Notes bear interest at a rate of 11.5% per annum. Interest is payable quarterly in arrears on January 15, April 15, July 15, and October 15 of each year. Each $1,000 principal amount of the Series 1 Notes and Series 2 Notes is initially convertible into 687.8525 and 412.7115 shares of the Company’s Class A common stock, which is equivalent to an initial conversion price of approximately $1.45 and $2.42 per share, respectively. The conversion rate is subject to adjustment upon the occurrence of certain specified events prior to the maturity date. The 2030 Convertible Notes are convertible at the option of the holders at any time before the maturity date, at the conversion price then in effect plus a make-whole premium (the “Make-Whole Premium”) equal to the lesser of (i) all regularly scheduled interest payments that would be due on the portion of such 2030 Convertible Note being redeemed for the succeeding two year period and (ii) all regularly scheduled interest payments that would be due on the portion of such 2030 Convertible Note being redeemed through the maturity date, and is capped at the maximum number of shares that would be issuable in connection with a conversion following a “Make-Whole Fundamental Change”, as defined in the indenture governing the 2030 Convertible Notes (the “Second Lien Indenture”). The Make-Whole Premium will be payable in either cash or shares, at the Company’s option. The Company accounted for the conversion option of Series 1 Notes and Series 2 Notes as embedded derivatives. The initial fair value of the derivative instruments of $25.2 million and $24.0 million was recorded as a liability in the consolidated balance sheet with the corresponding amount recorded as a discount to Series 1 Notes and Series 2 Notes, respectively, upon issuance. The Company will remeasure the derivative liabilities at each reporting period with any changes to be recorded in Other income, net in the condensed consolidated statements of operations. If a fundamental change, as defined in the Second Lien Indenture, occurs, then holders may require the Company to repurchase their 2030 Convertible Notes at a cash repurchase price equal to 100% of the principal amount of the 2030 Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. A holder that elects to convert its 2030 Convertible Notes in connection with a fundamental change may be entitled to receive a make-whole adjustment in connection with such corporate event in certain circumstances. The definition of fundamental change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Common Stock. The Company may redeem the 2030 Convertible Notes at its option, in whole at any time or in part from time to time, if the closing price of the Company’s common stock exceeds 130% of the conversion price for a given Series then in effect for at least 20 trading days (whether or not consecutive) during any 30 day 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, and certain liquidity conditions are then satisfied, at a redemption price equal to (i) 100% of the principal amount of the 2030 Convertible Notes to be redeemed, plus (ii) accrued and unpaid interest to, but excluding the redemption date, and (iii) the Make-Whole Premium. The 2030 Convertible Notes are guaranteed by certain of the Company’s current and future material subsidiaries on a second-priority senior secured basis, subject to certain criteria and exceptions. The 2030 Convertible Notes and the guarantees are secured by a fully perfected second-priority lien on substantially all of the assets of the Company and the Guarantors, subject to the first-priority liens securing or otherwise permitted by the Senior Notes and any first-priority liens on customary asset-based lending collateral, including accounts receivable and inventory, pursuant to a revolving credit facility permitted under the Second Lien Indenture. The Second Lien Indenture includes restrictive covenants substantially similar to the First Lien Indenture that, among other things, limit the ability of the Company and its subsidiaries to incur additional debt, make restricted payments and grant or incur liens, in addition to a financial covenant to maintain an unrestricted cash and cash equivalents balance, plus any unused commitments then available to be drawn under any revolving credit facility permitted under the Second Lien Indenture, of not less than $31.5 million as of the last day, or for more than five days, of any calendar month. The Second Lien Indenture also contains customary events of default. The Company has classified the 2030 Convertible Notes as a non-current liability. Initial debt discount (including the initial fair value of the embedded derivative liabilities) and issuance costs aggregating approximately $21.6 million and $33.3 million were initially recorded as a reduction to the principal amount of the Series 1 Notes and Series 2 Notes, respectively, and will be amortized as interest expense over the contractual terms of the 2030 Convertible Notes based on the effective interest rates of 16.3% and 16.3%, respectively. During the quarter ending September 30, 2024, the principal amount of $22.9 million and $50,000 of Series 1 Notes and Series 2 Notes were converted by the holders. The Company issued 20,328,198 shares and 33,069 shares of the Class A Common Stock to settle such conversion of Series 1 Notes and Series 2 Notes, respectively. The Company recognized a debt extinguishment gain of $5.1 million on such conversions which was recorded in Other income, net in the condensed consolidated statements of operations. The Company recognized interest expense of $1.1 million and $3.8 million for the Series 1 Notes and Series 2 Notes, respectively, during the three and nine months ended September 30, 2024, which included $0.3 million and $0.6 million, respectively, from the amortization of debt discount and issuance costs. The net carrying amount of the 2030 Convertible Notes as of September 30, 2024 was as follows (in thousands): Series 1 Notes Series 2 Notes Principal $ 59,391 $ 191,918 Unamortized debt discount and issuance costs (15,305) (32,702) Net carrying amount $ 44,086 $ 159,216 The remaining term over which the debt discount and issuance costs will be amortized is 5.3 years. The conversion features of the Series 1 Notes and Series 2 Notes are accounted for as embedded derivative liabilities. The derivative liability is considered a Level 3 valuation and is recorded at its estimated fair value at the end of each reporting period, with the change in fair value recognized within other expense, net in the consolidated statements of operations. The following table shows the estimated fair value of the derivative liability as of the issuance and the change in fair value from issuance through September 30, 2024: Series 1 Notes Series 2 Notes Derivative liability, at issuance $ 25,254 $ 23,980 Change in fair value (2,379) (97) Decrease of derivative liability upon exercise of conversion option $ (6,684) $ — Derivative liability, end of period $ 16,191 $ 23,883 The Company estimated the fair value of the 2030 Convertible Notes and derivative liability using a binomial model, with the following valuation inputs: Series 1 Notes Series 2 Notes August 8, 2024 September 30, 2024 August 8, 2024 September 30, 2024 Conversion price $ 1.45 $ 1.45 $ 2.42 $ 2.42 Risk-free rate 3.76 % 3.53 % 3.76 % 3.53 % Effective borrowing rate 17.16 % 12.84 % 17.16 % 12.84 % Volatility 50.00 % 50.00 % 50.00 % 50.00 % Stock price $ 0.93 $ 0.90 $ 0.93 $ 0.90 Payment interest rate 9.00 % 9.00 % 11.50 % 11.50 % Redemption price $ 1.89 $ 1.89 $ 3.15 $ 3.15 Credit Facility In February 2024, the Company entered into two non-recourse loan and securities pledge agreements (the “Loan Agreements”) with The St. James Bank & Trust Company Ltd. (the “Lender”), pursuant to which the Company may borrow up to an aggregate of $50.0 million (the “Credit Facility”). Any loans made by the Lender under the Loan Agreements would be collateralized by shares of the Company’s Class A common stock or stock the Company holds as investments in other companies. The Loan Agreements require the Company to pay an up-front structure fee of 1.5% on any amounts borrowed, and any outstanding amounts would bear interest at 8.0% per annum. The Company has not borrowed any amounts under the Credit Facility and had no outstanding balance as of September 30, 2024.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements As of September 30, 2024, the Company carried cash equivalents, marketable investments, embedded derivatives associated with 2030 Convertible notes and Private Warrants that are measured at fair value on a recurring basis. Additionally, the Company measures its equity-settled fixed value awards at fair value on a recurring basis. See Note 12 for further information on the Company’s fixed value equity awards. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 inputs, such as 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 based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques. The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments. Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations, alternative pricing sources or U.S. Government Treasury yield of appropriate term. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. The Company performs routine procedures such as comparing prices obtained from independent source to ensure that appropriate fair values are recorded. Given that the transfer of Private Warrants to anyone outside of a small group of individuals constituting the sponsors of Gores Metropoulos, Inc. (“Gores”) would result in the Private Warrants having substantially the same terms as warrants issued in connection with the initial public offering of Gores (“Public Warrants”), management determined that the fair value of each Private Warrant is the same as that of a Public Warrant, with an insignificant adjustment for short-term marketability restrictions. The fair value of the Private Warrants was de minimis as of September 30, 2024. The Company’s financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used for such measurements were as follows (in thousands): Fair Value Measured as of September 30, 2024: Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 60,792 $ — $ — $ 60,792 U.S. treasury securities 15,199 — — 15,199 Commercial paper — 5,182 — 5,182 Total cash equivalents $ 75,991 $ 5,182 $ — $ 81,173 Marketable investments: U.S. treasury securities $ 9,139 $ — $ — $ 9,139 Commercial paper — 4,172 — 4,172 Corporate bonds — 67,733 — 67,733 Certificate of deposit — 500 — 500 Marketable equity investments 2,865 — — 2,865 Total marketable investments $ 12,004 $ 72,405 $ — $ 84,409 Liabilities: Derivative liability $ — $ — $ 40,074 $ 40,074 Private Warrants $ — $ — $ 19 $ 19 Total liabilities $ — $ — $ 40,093 $ 40,093 Fair Value Measured as of December 31, 2023: Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 101,842 $ — $ — $ 101,842 Commercial paper — 497 — 497 Corporate bonds — 1,097 — 1,097 Total cash equivalents $ 101,842 $ 1,594 $ — $ 103,436 Marketable investments: U.S. treasury securities $ 86,784 $ — $ — $ 86,784 U.S. agency and government sponsored securities — 2,732 — 2,732 Commercial paper — 9,647 — 9,647 Corporate bonds — 43,809 — 43,809 Marketable equity investments 7,755 — — 7,755 Total marketable investments $ 94,539 $ 56,188 $ — $ 150,727 Liabilities: Private Warrants $ — $ — $ 1,069 $ 1,069 As of September 30, 2024 and December 31, 2023, the estimated fair value of the Company’s outstanding 2026 Convertible Senior Notes was $94.8 million and $296.3 million, respectively. The fair value was determined based on the quoted price of the 2026 Convertible Senior Notes in an inactive market on the last trading day of the reporting period and have been classified as Level 2 in the fair value hierarchy. See Note 8 for further information on the Company’s 2026 Convertible Senior Notes. As of September 30, 2024, the estimated fair value of the Series 1 Notes and Series 2 Notes, excluding the embedded feature value was $52.4 million and $187.9 million, respectively. As of September 30, 2024, the estimated fair value of the Senior Notes was $108.0 million. The fair value was determined based on a binomial lattice model and have been classified as Level 3 in the fair value hierarchy. See Note 8 for further information on these notes. The fair value of Company’s other financial instruments, including accounts receivable, accounts payable and other current liabilities, approximate their carrying value due to the relatively short maturity of those instruments. The carrying amounts of the Company’s finance leases approximate their fair value, which is the present value of expected future cash payments based on assumptions about current interest rates and the creditworthiness of the Company.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated by dividing net income by the weighted-average number of common shares and potentially dilutive securities outstanding during the period using the treasury stock method for the employee equity incentive plans and stock-based awards, and the if-converted method for the 2026 Convertible Senior Notes and 2030 Convertible Notes. If the Company reports a net loss, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents, as their effect would be antidilutive. The Company computes earnings (loss) per share using the two-class method for its Class A and Class B common stock. Earnings (loss) per share is same for both Class A and Class B common stock since they are entitled to the same liquidation and dividend rights. The following table sets forth the computation of basic and diluted income/(loss) per share for the three and nine months ended September 30, 2024 and 2023 (in thousands, except for share and per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Numerator: Net income (loss) $ 27,403 $ (134,338) $ (228,918) $ (422,868) 2026 Convertible Senior Notes extinguishment (141,203) — (141,203) — 2030 Convertible Notes extinguishment $ (5,355) $ — $ (5,355) $ — Net income (loss) attributable to common shareholders $ (119,155) $ (134,338) $ (375,476) $ (422,868) Denominator: Weighted average common shares outstanding—Basic 480,016,365 394,591,942 453,074,622 382,673,871 Dilutive effect of potential common shares 2026 Convertible Senior Notes extinguished 8,817,633 — 17,016,484 — 2030 Convertible Notes 5,180,954 — 1,726,985 — Weighted average common shares outstanding—Diluted 494,014,952 394,591,942 471,818,091 382,673,871 Net income (loss) per share Basic $ 0.06 $ (0.34) $ (0.51) $ (1.11) Diluted $ (0.24) $ (0.34) $ (0.80) $ (1.11) The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share of common stock as of the periods presented because including them would have been antidilutive or related contingencies on issuance of shares had not been met for the three and nine months ended September 30, 2024: September 30, 2024 Warrants 5,757,549 Stock-based awards—Equity classified 35,494,946 Stock-based awards—Liability classified 37,743,480 Vendor stock-in-lieu of cash program 6,314,814 Series 1 Notes 48,821,579 Series 2 Notes 112,112,553 2026 Convertible Senior Notes 10,163,806 Earn-out shares 8,606,717 Total 265,015,444

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Class A and Class B Common Stock The Company’s board of directors (the “Board”) has authorized two classes of common stock, Class A and Class B. As of September 30, 2024, the Company had authorized 715,000,000 shares of Class A common stock and 121,000,000 shares of Class B common stock with a par value of $0.0001 per share for each class. As of September 30, 2024, the Company had 422,694,997 shares issued and 400,831,547 shares outstanding of Class A common stock, and 97,088,670 shares issued and outstanding of Class B common stock. Holders of Class A and Class B common stock have identical rights, except that holders of the Class A common stock are entitled to one vote per share and the holder of the Class B common stock is entitled to ten votes per share. See Note 17. Subsequent Event for a description of the Reverse Stock Split (as defined below). Equity Financing Program On February 28, 2023, the Company entered into an agreement (the “2023 Sales Agreement”) with Virtu Americas LLC (the “Agent”) under which the Company may offer and sell, from time to time in its sole discretion, shares of the Company’s Class A common stock with aggregate gross sales proceeds of up to $75.0 million through an equity offering program under which the Agent will act as sales agent (the “Equity Financing Program”). The Company completed sale of common stock under the 2023 Sales Agreement in March 2024 . On May 3, 2024, the Company entered into an agreement (the “2024 Sales Agreement”) with the Agent, which extended the Equity Financing Program under the 2023 Sales Agreement. Under the 2024 Sales Agreement, the Company may offer and sell, from time to time in its sole discretion, shares of the Company’s Class A common stock with aggregate gross sales proceeds of up to an additional $150.0 million under the Equity Financing Program. The Company intends to use the net proceeds, if any, from offerings under this program for expenditures or payments in connection with mergers and acquisitions, strategic investments, partnerships and similar transactions, repurchases of outstanding convertible debt securities, and if needed, for general corporate and business purposes. In August 2024, the Company increased the Equity Financing Program by an additional $50.0 million pursuant to the 2024 Sales Agreement. Under the 2024 Sales Agreement, the Company sets the parameters for the sale of the shares, including the number of shares to be issued, the time period during which sales are requested to be made, limitations on the number of shares that may be sold in any one trading day and any minimum price below which sales may not be made. Subject to the terms and conditions of the 2024 Sales Agreement, the Agent has agreed to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to sell the shares by methods deemed to be an “at the market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, (the “Securities Act”), including sales made through The Nasdaq Global Select Market. The Company issued 4,000,000 and 24,001,276 shares of Class A common stock under the Equity Financing Program during the three and nine months ended September 30, 2024 for net proceeds of $5.9 million and $41.8 million, respectively. As of September 30, 2024, the amount available for sale under the 2024 Sales Agreement was $182.1 million.

Stock-based Compensation	9 Months Ended

Share-Based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation Prior to becoming a publicly traded entity, the Company issued incentive stock options, non-qualified stock options, and restricted stock to employees and non-employee consultants under its 2015 Stock Plan (the “2015 Plan”). Since the closing of the business combination between Gores Metropoulos, Inc. and Luminar Technologies, Inc. on December 2, 2020 (the “Business Combination”), the Company has not issued any new stock-based awards under the 2015 Plan. In December 2020, the Board adopted, and the Company’s stockholders approved the 2020 Equity Incentive Plan (the “2020 Plan”). The 2020 Plan became effective upon the closing of the Business Combination. Under the 2020 Plan, the Company was originally authorized to issue a maximum number of 36,588,278 shares of Class A common stock. In June 2022, the Company’s stockholders approved an amendment and restatement of the Company’s 2020 Plan (the “Amended 2020 Plan”) to increase the number of shares of Class A common stock authorized for issuance by 36,000,000 additional shares and added an evergreen provision under which the number of shares of Class A common stock available for issuance under the Amended 2020 Plan will be increased on the first day of each fiscal year of the Company beginning with the 2023 fiscal year and ending on (and including) the first day of the 2030 fiscal year, in an amount equal to the lesser of (i) 5% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year, (ii) 40,000,000 shares or (iii) such number of shares determined by the Board. Pursuant to the evergreen provision, 20,991,566 additional shares of Class A common stock were added to the Amended 2020 Plan on January 1, 2024. In June 2024, the Company’s stockholders approved an amendment and restatement of the Company’s Amended 2020 Plan (the “Amended and Restated EIP”) to increase the number of shares of Class A common stock authorized for issuance by 20,000,000 additional shares of Class A common stock. In May 2024, the Company announced the suspension of the employer match to the 401k plan. As of June 14, 2024, the Company will no longer match the 401k plan contributions made by the employee. This is part of the cost reduction initiatives undertaken by management. Stock Options Under the terms of the 2015 Plan, incentive stock options had an exercise price at or above the fair market value of the stock on the date of the grant, while non-qualified stock options were permitted to be granted below fair market value of the stock on the date of grant. Stock options granted have service-based vesting conditions only. The service-based vesting conditions vary, though typically, stock options vest over four years with 25% of stock options vesting on the first anniversary of the grant and the remaining 75% vesting monthly over the remaining 36 months. Option holders have a 10-year period to exercise their options before they expire. Forfeitures are recognized in the period of occurrence. As part of the restructuring severance package in connection with the May 2024 Plan, the Company granted 1,003,765 options under the Amended and Restated EIP. These options are fully vested at the time of grant and have a 6-year exercise period before expiration, but they may not be exercised prior to May 5, 2028. The Company’s stock option activity for the nine months ended September 30, 2024 was as follows: Number of Weighted- Weighted- Aggregate Outstanding as of December 31, 2023 6,199,453 $ 1.76 Granted 981,462 1.50 Exercised (327,499) 1.67 Cancelled/Forfeited (410,127) 2.79 Outstanding as of September 30, 2024 6,443,289 1.66 4.80 $ 185 The aggregate intrinsic value of stock options exercised during the nine months ended September 30, 2024 was $0.2 million. The intrinsic value is calculated as the difference between the exercise price and the fair value of the common stock on the exercise date. The total grant date fair value of stock options vested during the nine months ended September 30, 2024 was $1.6 million. Restricted Stock units Since the closing of the Business Combination, the Company has granted restricted stock units (“RSUs”) under the 2020 Plan, the Amended 2020 Plan and the Amended and Restated EIP (together, the “EIP”). Each RSU granted under the EIP represents a right to receive one share of the Company’s Class A common stock when the RSU vests. RSUs generally vest over a period up to six years. The Company has granted certain performance-based equity awards that vest upon achievement of certain performance milestones. The fair value of RSUs is equal to the fair value of the Company’s common stock on the date of grant. The Company’s Time-Based RSUs and Performance-Based and Other RSUs activity for the nine months ended September 30, 2024 was as follows: Time-Based RSUs Performance-Based and Other RSUs Shares Weighted Average Shares Weighted Average Outstanding as of December 31, 2023 31,251,698 $ 8.60 266,921 $ 8.91 Granted 30,288,936 1.60 179,452 1.92 Forfeited (11,833,368) 5.12 (30,770) 8.58 Vested (23,341,709) 5.02 (343,071) 5.10 Change in units based on performance — — 2,220 8.58 Outstanding as of September 30, 2024 26,365,557 5.29 74,752 9.77 Fixed Value Equity Awards The Company issues fixed value equity awards to certain employees as a part of their compensation package. These awards are issued as RSUs under the EIP and are accounted for as liability classified awards under ASC 718 — Stock Compensation. Fixed value equity awards granted have service-based conditions only and vest quarterly over a period of up to six years. These awards represent a fixed dollar amount settled in a variable number of shares determined at each vesting period. Stock-based compensation expense related to these awards was $3.6 million and $11.5 million for the three and nine months ended September 30, 2024, respectively, and $4.2 million and $10.1 million for the three and nine months ended September 30, 2023, respectively. Freedom Photonics Awards As part of the acquisition of Freedom Photonics LLC (“Freedom Photonics”) in April 2022, the Company owed up to $29.8 million of post combination compensation related to certain service and performance conditions including achievement of certain technical and financial milestones. In March 2024, the Company issued 2,651,085 shares of Class A common stock for $5.4 million of the post combination compensation due to achievement of the service and performance conditions. In May 2024, the Company issued 3,098,974 shares of Class A common stock for $5.5 million of the post combination compensation due to achievement of the service and performance conditions. In June 2024, the Company issued 1,689,400 shares of Class A common stock for $2.5 million of the post combination compensation due to achievement of the certain milestones. As of September 30, 2024, it is probable that the remaining conditions will be met for an amount equal to approximately $4.5 million of post combination compensation. Management Awards On May 2, 2022, the Board granted an award of 10.8 million RSUs to Austin Russell, the Company’s Chief Executive Officer. The grant date fair value per share of the award granted to Mr. Russell was $8.70 per share. On August 19, 2022, the Board granted 500,000 RSUs to each of Thomas Fennimore, the Company’s Chief Financial Officer, and Alan Prescott, the Company’s Chief Legal Officer. The grant date fair value per share of the awards granted to Mr. Fennimore and Mr. Prescott was $6.12 per share. These awards to Mr. Russell, Mr. Fennimore and Mr. Prescott are subject to all of the following vesting conditions: • Public Market condition: Achievement of three stock price milestones: $50 or more, $60 or more, and $70 or more. The stock price will be measured based on the volume-weighted average price per share for 90 consecutive trading days; • Service condition: Approximately 7-years of vesting; and • Performance condition: Start of production for at least one series production program. On June 4, 2024, the Board granted 687,499 RSUs to an executive, contingent upon market-based performance conditions. The grant date fair value of the award was $1.15 per share. The Company measured the compensation cost for the management awards outlined above using a Monte Carlo simulation model and recorded $5.8 million and $17.2 million in stock-based compensation expense related to these awards in the three and nine months ended September 30, 2024, respectively. The Company’s management awards activity for the nine months ended September 30, 2024 was as follows: Shares Weighted Average Outstanding as of December 31, 2023 11,800,000 $ 8.48 Granted 687,499 1.15 Outstanding as of September 30, 2024 12,487,499 8.07 On November 8, 2023, the Board approved a formula for RSU grants to Messrs. Fennimore and Prescott for each year from 2024 through 2029 for Mr. Fennimore and through 2026 for Mr. Prescott based on achievement of annual performance goals with respect to the immediately preceding year (“Annual Performance Award”). The number of RSUs to be awarded in a year will be determined at the sole discretion of the Human Resources and Compensation Committee of the Board (the “Compensation Committee”) based on actual achievement of the annual performance goals established by the Board based on the Company’s approved operating plan in respect of the immediately preceding year, with such awards ranging from 137,500 RSUs at the threshold level, 550,000 RSUs at the target level, and 825,000 RSUs at the maximum level for extraordinary performance (interpolated linearly between target levels, as applicable). For a potential award to be made in 2024, the Compensation Committee had determined that annual performance goals will be weighted 50% based on revenue and 50% based on free cash flow, with target performance for the revenue performance goal equal to $81.4 million and target performance for the 2023 fourth quarter free cash flow goal equal to $(37) million. In March 2024, the Compensation Committee determined that the achievement of the 2023 performance goals was below the threshold level. Accordingly, no 2023 Annual Performance Award was granted to Messrs. Fennimore and Prescott in March 2024.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase and Other Obligations The Company purchases goods and services from a variety of suppliers in the ordinary course of business. Purchase obligations are defined as agreements that are enforceable and legally binding and that specify all significant terms, including fixed or minimum quantities to be purchased, fixed, minimum, or variable price provisions, and the approximate timing of the transaction. The Company had purchase obligations primarily for purchases of inventory, R&D, and general and administrative activities totaling $115.8 million as of September 30, 2024. Legal Matters From time to time, the Company is involved in actions, claims, suits and other proceedings in the ordinary course of business, including assertions by third parties relating to intellectual property infringement, breaches of contract or warranties or employment-related matters. When it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated, the Company records a liability for such loss contingencies. The Company’s estimates regarding potential losses and materiality are based on the Company’s judgment and assessment of the claims utilizing currently available information. Although the Company will continue to reassess its reserves and estimates based on future developments, the Company’s objective assessment of the legal merits of such claims may not always be predictive of the outcome and actual results may vary from the Company’s current estimates. The Company’s current legal accrual is not material to the financial statements. On May 26, 2023, a putative class action styled Johnson v. Luminar Technologies, Inc., et al., Case No. 6:23-cv-00982-PGB-LHP, was filed in the United States District Court for the Middle District of Florida, against the Company and an employee. The suit asserts purported claims on behalf of purchasers of the Company’s securities between February 28, 2023 and March 17, 2023 under Sections 10(b) and 20(a) of the Exchange Act for allegedly misleading statements regarding the Company’s photonic integrated circuits technology. Defendants filed a motion to dismiss the complaint on December 29, 2023, the motion was granted, and on July 8, 2024 Plaintiff filed an amended complaint. Defendants filed a motion to dismiss the amended complaint on August 22, 2024, which remains pending. The Company disputes the allegations in the complaint and intends to vigorously defend the litigation. The Company presently does not expect this matter to have a material adverse impact on the Company’s financial results and did not accrue anything related to this matter as of September 30, 2024. On October 21, 2023, a shareholder derivative suit entitled Bhavsar v. McAuliffe, et al. Bhavsar v. McAuliffe, et al., No. 6:23-cv-02037 was filed in the United States District Court for the Middle District of Florida against directors of the Company and an employee. The suit avers claims for purported breaches of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste, aiding and abetting, and contribution under Sections 10(b) and 21D of the Exchange Act on the basis of the same purported wrongdoing alleged in the first lawsuit described above. In November 2023, three additional shareholder derivative suits averring similar claims to Bhavsar were filed in the United States District Court for the District of Delaware: Lance Dechant, et al. v. Alec E. Gores, et al. , C.A. No. 23-cv-01318-UNA, Hutchinson v. Russell, et al. , C.A. No. 23-cv-01345-UNA, and Ulerio v. Russell, et al. , C.A. No. 23-cv-01359-UNA. The Company disputes the allegations in these complaints and intends to vigorously defend the litigation. The Company has determined that the likelihood of this matter resulting in a material adverse impact on the Company’s financial results is remote. On March 21, 2024, a putative class action styled Smith v. Gores, et al., C.A. No. 2024-0285-MTZ (Del. Ch.) was filed in the Delaware Court of Chancery against the Company and the members of its Board of Directors. The lawsuit asserted claims on behalf of a putative class comprised of all stockholders other than defendants and any current directors or officers of the Company. The plaintiff alleged that certain provisions in the Company’s advance notice bylaws (the “Challenged Provisions”) were invalid and void and that the members of the Board have breached their fiduciary duty of loyalty by adopting and maintaining the Challenged Provisions. In addition to seeking declaratory, equitable, and injunctive relief, the plaintiff sought an award of attorneys’ fees and other costs and expenses on behalf of the putative class. On September 4, 2024, the court granted the parties stipulation to dismiss this action with prejudice, as to the individual plaintiff only, in light of certain amendments to the Challenged Provisions adopted by the Board, which rendered the action moot. The court retains jurisdiction of the action solely for the purpose of adjudicating an attorneys’ fees and expenses application by the plaintiff. The Company has determined that the likelihood of this matter resulting in a material adverse impact on the Company’s financial results is remote.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event On October 15, 2024, we received a deficiency notice from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) notifying that, based on the closing bid price of our Common Stock, for the last 30 consecutive trading days, we no longer comply with the minimum bid price requirement for continued listing on The Nasdaq Global Select Market. Nasdaq Listing Rule 5450(a)(1) requires listed securities to maintain a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”), and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the Minimum Bid Price Requirement exists if the deficiency continues for a period of 30 consecutive trading days. The Notice has no immediate effect on the listing of the Common Stock on The Nasdaq Global Select Market. The Company has 180 days from the date of the Notice to regain compliance and is considering all available options to comply with the Minimum Bid Price Requirement. On October 30, 2024, the Company held its special meeting of stockholders (the “Special Meeting”). At the Special Meeting, the Company’s stockholders approved an amendment to the Company’s Second Amended and Restated Certificate of Incorporation, as amended, to, at the discretion of the Board, effect a reverse stock split (the “Reverse Stock Split”) with respect to the Company’s issued and outstanding Class A common stock and Class B common stock, including any held by the Company as treasury shares, at any time prior to December 31, 2024, at a ratio of 1-for-5 to 1-for-20 (the “Range”), with the ratio within such Range to be determined at the discretion of the Board without further approval or authorization of the Company’s stockholders.On November 13, 2024, the Board set and approved a ratio of 1-for-15 for the Reverse Stock Split and authorized management to proceed with the reverse stock split.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”) filed with the SEC on February 28, 2024. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances 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 judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses, and related disclosures. The significant estimates made by management include inventory reserves, useful life of long-lived assets, valuation allowance for deferred tax assets, valuation of warrants issued in a private placement (“Private Warrants”), valuation of contingent consideration payable, and assets acquired in mergers and acquisitions including intangible assets, forecasted costs associated with non-recurring engineering (“NRE”) services, restructuring costs, valuation of convertible and senior notes and derivatives associated with them, valuation of distinct goods and services in the purchase contract with customers and stock-based compensation expense. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates.
Derivative Liability	Derivative Liability The Company evaluated convertible and senior notes to determine if embedded features of those contracts qualify as derivatives to be separately accounted for under the relevant sections of Accounting Standards Codification ("ASC") 815-40, Derivatives and Hedging: Contracts in Entity’s Own Equity. This accounting treatment requires that the carrying amount of any derivatives be recorded at fair value in the consolidated balance sheet at issuance and marked-to-market at each balance sheet date as components of convertible and senior notes. The change in the fair value during the period is recorded in the consolidated statement of operations as either other income or expense as changes in fair value of derivative liability. Upon conversion, exercise or repayment, the respective derivative liability is marked to fair value at the conversion, repayment, or exercise date and then the related fair value amount is reclassified to other income or expense as part of gain or loss on debt extinguishment in the consolidated statement of operations.
Segment Information	Segment Information The Company has determined its operating segments using the same indicators which were used to evaluate its performance internally. The Company’s business activities are organized in two operating segments: (i) “Autonomy Solutions” which includes manufacturing and distribution of LiDAR sensors that measure distance using laser light to generate a 3D map, non-recurring engineering services related to the Company’s LiDAR products, development of software products that enable autonomy capabilities for automotive applications, and licensing of certain information. In June 2022, the Company acquired certain assets from Solfice Research, Inc. (“Solfice” or “Civil Maps”). In January 2023, the Company acquired certain assets from Seagate Technology LLC and Seagate Singapore International Headquarters Pte. Ltd. (individually and collectively, “Seagate”). Assets purchased from both Civil Maps and Seagate have been included in the Autonomy Solutions segment. (ii) “Advanced Technologies and Services (“ATS”) which includes the design, development, manufacturing, packaging and development services of photonic components and subsystems (including semiconductor lasers and photodetectors), application-specific integrated circuits and pixel-based sensors. The Company acquired Optogration, Inc. (“Optogration”) in August 2021, Freedom Photonics LLC (“Freedom Photonics”) in April 2022, and EM4, LLC (“EM4”) in March 2024. Operations of Optogration, Freedom Photonics and EM4 have been included in the ATS segment since their respective acquisition dates.
Concentration of Credit Risk	Concentration of Credit Risk The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, debt securities and accounts receivable. The Company’s deposits exceed federally insured limits. Cash held by foreign subsidiaries of the Company as of September 30, 2024 and December 31, 2023 was not material.
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires a public company to enhance the transparency and decision usefulness of income tax disclosures to provide information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. ASU 2023-09 will be effective for the Company for the annual period beginning January 1, 2025 with early adoption permitted. The Company is currently evaluating this guidance and the impact it may have on its financial statement disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 requires a public company to enhance disclosures about significant segment expenses and provide incremental segment information on an annual and interim basis to enable investors to develop more decision-useful financial analyses. ASU 2023-07 will be effective for the Company for fiscal year beginning January 1, 2024, and interim periods within fiscal year beginning January 1, 2025, with early adoption permitted. The Company is currently evaluating this guidance and the impact it may have on its financial statement disclosures.
Fair Value Measurements	Fair Value Measurements As of September 30, 2024, the Company carried cash equivalents, marketable investments, embedded derivatives associated with 2030 Convertible notes and Private Warrants that are measured at fair value on a recurring basis. Additionally, the Company measures its equity-settled fixed value awards at fair value on a recurring basis. See Note 12 for further information on the Company’s fixed value equity awards. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 inputs, such as 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 based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques. The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.
