Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business Ouster, Inc. was incorporated in the Cayman Islands on June 4, 2020 as “Colonnade Acquisition Corp.” (“CLA”). Following the closing of the business combination in March 2021, the Company domesticated as a Delaware corporation and changed its name to “Ouster, Inc.” The Company’s prior operating subsidiary, Ouster Technologies, Inc. (“OTI” and prior to the Merger (as defined below)), was incorporated in the state of Delaware on June 30, 2015. The Company is a leading provider of high-resolution digital lidar sensors that offer advanced 3D vision to machinery, vehicles, robots, and fixed infrastructure assets, allowing each to understand and visualize the surrounding world and ultimately enabling safe operation and ubiquitous autonomy. Unless the context otherwise requires, references in this subsection to “the Company” refer to the business and operations of OTI (formerly known as Ouster, Inc.) and its consolidated subsidiaries prior to the Merger (as defined below) and to Ouster, Inc. (formerly known as CLA) and its consolidated subsidiaries following the consummation of the Merger. CLA, the Company’s legal predecessor, was originally a blank check company incorporated as a Cayman Islands exempted company on June 4, 2020. CLA was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On March 11, 2021, CLA consummated a merger (the “Merger”) with OTI pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) dated as of December 21, 2020. The Merger was accounted for as a reverse recapitalization, CLA is treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of OTI with the Merger being treated as the equivalent of OTI issuing stock for the net assets of CLA, accompanied by a recapitalization whereby no goodwill or other intangible assets are recorded. Transactions and balances prior to the Merger are those of OTI. On February 10, 2023, the Company completed the merger with Velodyne Lidar, Inc., a Delaware corporation (“Velodyne”) pursuant to the terms of the Agreement and Plan of Merger (the “Velodyne Merger Agreement”) with Velodyne, Oban Merger Sub, Inc. (“Merger Sub I”) and Oban Merger Sub II LLC (“Merger Sub II”) (the “Velodyne Merger”) dated as of November 4, 2022, accounted for as a business combination with the Company being an accounting acquiror (Note 3). Basis of Presentation and Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries (all of which are wholly owned) and have been prepared in conformity with U.S. generally accepted accounting principles (“US GAAP”) applicable to interim periods. All intercompany balances and transactions have been eliminated in consolidation. The presentation of certain prior period amounts has been reclassified to conform with current year presentation. The unaudited condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the results of operations for the periods shown. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2022 and the notes related thereto, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 24, 2023. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. Certain information and note disclosures normally included in the audited financial statements prepared in accordance with US GAAP have been condensed or omitted from this report, as is permitted by applicable rules and regulations. The results of operations for any interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future years or interim periods. On April 6, 2023, the Board of Directors approved a one-for-10 reverse stock split and a corresponding reduction in authorized shares of common stock (the “Reverse Stock Split”). On April 20, 2023, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to its Certificate of Incorporation to effect the one-for-10 Reverse Stock Split of the Company’s common stock and a corresponding reduction in authorized shares of common stock. The par value of the Company’s common stock was not adjusted as a result of the Reverse Stock Split. All share and per share amounts and related stockholders’ equity balances presented herein have been retroactively adjusted to reflect the Reverse Stock Split. Liquidity The Company’s principal sources of liquidity are its cash and cash equivalents and short-term investments funded through the Merger and the Velodyne Merger, cash generated from revenues, sales of common stock under its at-the market equity offering program and the Loan Agreement with Hercules Capital, Inc. As of June 30, 2023, the Company’s existing sources of liquidity included cash, cash equivalents and short-term investments of $224.4 million. The Company has incurred losses and negative cash flows from operations for several years. If the Company continues to incur losses in the future, it may need to improve liquidity and raise additional capital through the issuance of equity and/or debt. There can be no assurance that the Company would be able to raise such capital. However, management believes that the Company’s existing sources of liquidity are adequate to fund its operations for at least twelve months from the date the condensed consolidated financial statements were available for issuance.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies During the six months ended June 30, 2023, there were no significant changes to the Company’s significant accounting policies as disclosed in the Company’s Annual Report on Form 10-K filed with the SEC on March 24, 2023, except for the changes described below. The Company has consistently applied the accounting policies to all periods presented in these condensed consolidated financial statements. Revenue Recognition The Company recognizes revenue when a customer obtains control of promised products or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these products or services. To achieve the core principle of this standard, the Company performs the following five steps: 1) Identify the contract with a customer A contract with a customer exists when the contract is approved, each party’s rights regarding the product or services to be transferred and the payment terms for the product or services can be identified, it is determined that the customer has the ability and intent to pay and the contract has commercial substance. The Company applies judgement in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer. Accounts receivable are due under normal trade terms, typically three months or less. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the product or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the product or services is separately identifiable from other promises in the contract. 3) Determine the transaction price The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring product or services to the customer. Royalties from the license of IP are included in the transaction price in the period the sales occur. Other forms of variable consideration are included in the transaction price if the Company judges that it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component. All taxes assessed by a governmental authority on a specific revenue-producing transaction collected by the Company from a customer are excluded from the transaction price. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). In the three and six months ended June 30, 2023 and 2022, respectively, the Company did not have a material volume of contracts that required the allocation of transaction price to multiple performance obligations. 5) Recognize revenue when or as the Company satisfies a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to a customer. Product revenue The majority of the Company’s revenue comes from product sales of lidar sensors to direct customers and distributors. Revenue is recognized at a point in time when control of the goods is transferred to the customer, generally occurring upon shipment or delivery dependent upon the terms of the underlying contract. Product sales to certain customers may require customer acceptance due to performance acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon the expiration of the customer acceptance period. For custom products that require engineering and development based on customer requirements, the Company recognizes revenue over time using an output method based on units of product shipped to date relative to total production units under the contract. Amounts billed to customers for shipping and handling are included in revenue, and the Company has elected to recognize the cost of shipping activities that occur after control has transferred to the customer as a fulfillment cost rather than a separate performance obligation. All related shipping costs are accrued and recognized within cost of revenue when the related revenue is recognized. Services The Company’s services revenue consists primarily of product development, validation services and providing maintenance services under our extended warranty contracts. The obligation to provide services is generally satisfied over time, with the customer simultaneously receiving and consuming the benefits as the Company satisfies its performance obligations. For product development and validation service projects, the Company bills and recognizes revenue as the services are performed. For these arrangements, control is transferred over as the Company’s inputs incurred to complete the project; therefore, revenue is recognized over the service period with the measure of progress using the input method based on labor costs incurred to total labor cost (“cost-to-cost”) as the services are provided. The revenue from the sale of extended warranties is recognized over the warranty period on a ratable basis as the Company stands ready to provide services as needed. Licenses The Company licenses rights to its IP to certain customers and collects royalties based on customer’s product sales. IP revenue recognition is dependent on the nature and terms of each agreement. The Company recognizes license revenue upon the later of (a) delivery of the IP or (b) commencement of the license term if there are no substantive future obligations to perform under the arrangement. Revenue for licenses to future technology developed on a when-and-if -available basis is recognized straight-line over the license period as long as customers continue to have access to the future technology. Royalties from the license of IP are recognized at the later of the period the sales occur or the satisfaction of the performance obligation to which some or all of the royalties have been allocated. Product Warranties The Company provides standard product warranties for a term of typically one two Costs to obtain a contract The Company expenses the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are expensed as incurred in sales and marketing expense in the Company’s consolidated statements of operations and comprehensive loss. Remaining performance obligations Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied. It includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods and does not include contracts where the customer is not committed. The customer is not considered committed where they are able to terminate for convenience without payment of a substantive penalty under the contract. Investments The Company considers investments with an original maturity greater than three months and remaining maturities less than one year to be short-term investments. The Company classifies those investments that are not required for use in current operations and that mature in more than 12 months as long-term investments. The Company classifies its investments as available for sale and reports them at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. For investments sold prior to maturity, the cost of investments sold is based on the specific identification method. Realized gains and losses on the sale of investments are recorded in other income, net in the condensed consolidated statement of operations. Amazon Warrant The Amazon Warrant (as defined in Note 7) is accounted for as an equity instrument. To determine the fair value of the Amazon Warrant on its issuance date, the Company used the Black-Scholes option pricing model. For awards granted to a customer, which are not in exchange for distinct goods or services, the fair value of the awards earned based on service or performance conditions is recorded as a reduction of the transaction price. Accordingly, when Amazon purchases goods or services and vesting conditions become probable of being achieved, the Company records a non-cash stock-based reduction to revenue associated with the Amazon Warrant, which is calculated based on the fair value of the Amazon Warrant shares as of the Velodyne Merger date. Recently Issued Accounting Pronouncements Not Yet Adopted The Company considers the applicability and impact of all ASUs. ASUs not referenced below were assessed and determined to be either not applicable or are not expected to have a material impact on the Company’s condensed consolidated financial statements. Concentrations of Credit Risk Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, restricted cash, short-term investments and accounts receivable. Cash, cash equivalents, restricted cash and short-term investments are deposited with federally insured commercial banks. At times, cash balances in the U.S. may be in excess of federal insurance limits. As of June 30, 2023 and December 31, 2022, the Company had cash, cash equivalents and restricted cash with financial institutions in the U.S. of $89.8 million and $123.5 million, respectively. As of June 30, 2023 and December 31, 2022, the Company also had cash on deposit with financial institutions in countries other than the U.S. of approximately $3.2 million and $0.8 million, respectively, that was not federally insured. The Company generally does not require collateral or other security deposits for accounts receivable. To reduce credit risk, the Company considers customer creditworthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms when determining the collectability of specific customer accounts. Past due balances over 90 days and other higher risk amounts are reviewed individually for collectability. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to valuation allowance. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. Accounts receivable from the Company’s major customers representing 10% or more of total accounts receivable was as follows: June 30, December 31, Customer A 33 % * Customer B 17 % * *Customer accounted for less than 10% of total accounts receivable in the period. No customer accounted for more than 10% of the total revenue in the three and six month ended June 30, 2023 and 2022, respectively. Concentrations of Supplier Risk Purchases from the Company’s major suppliers representing 10% or more of total purchases were as follows: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Supplier A 12 % * 11 % * Supplier B 28 % 38 % 21 % 37 % *Accounted for less than 10% of total purchases. Accounts payable to the Company’s major suppliers and professional services vendors representing 10% or more of total accounts payable were as follows: June 30, 2023 December 31, 2022 Supplier A * * Supplier B 49 % 39 % Professional Services Vendor A * 14 %

Business Combination and Asset Acquisition [Abstract]
Business Combination	Business CombinationOn February 10, 2023, the Company completed the Velodyne Merger. Velodyne shares ceased trading on the Nasdaq Stock Market LLC after market close on February 10, 2023, and each Velodyne share was exchanged for 0.8204 shares of the Company’s common stock. Velodyne is treated as the acquired company for financial reporting purposes. This determination is primarily based on the Company’s senior management prior to Velodyne Merger comprising a majority of the senior management of the Company following Velodyne Merger, the Company being the initiator of acquiring Velodyne and the Company being the party issuing shares in the Velodyne Merger. The acquisition price for the Velodyne Merger was $306.6 million, primarily consisting of fair value of the Company’s common stock issued in exchange for Velodyne shares and fair value of the Amazon Warrant (Note 7) of $8.6 million. Through June 30, 2023, transaction costs incurred by the Company in connection with the Velodyne Merger, including professional fees, were $13.0 million. Under the acquisition method of accounting in accordance with ASC 805, the total purchase price was allocated to identifiable tangible and intangible assets acquired and liabilities assumed based on their respective estimated fair values using management’s best estimates and assumptions to assign fair value as of the acquisition date. The following table provides the assets acquired and liabilities assumed as of the date of acquisition (in thousands): Estimated Fair Value Purchase consideration $ 306,602 Preliminary amounts of identifiable assets and liabilities assumed Cash and cash equivalents $ 32,137 Short-term investments 155,031 Accounts receivable, net 8,611 Inventory 9,700 Prepaid expenses and other current assets 4,387 Unbilled receivable, long-term portion 6,657 Property and equipment, net 9,900 Operating lease, right-of-use assets 10,887 Intangible assets, net 13,000 Other non-current assets 1,047 Accounts payable (3,356) Accrued and other current liabilities (32,821) Contract liabilities (5,475) Operating lease liability, current portion (3,735) Operating lease liability, long-term portion (11,940) Contract liabilities, long-term portion (2,206) Other non-current liabilities (745) Total identifiable net assets $ 191,079 Goodwill $ 115,523 $ 306,602 Under the acquisition method of accounting in accordance with ASC 805, the total purchase price was allocated to identifiable tangible and intangible assets acquired and liabilities assumed based on their estimated fair values using management’s best estimates and assumptions to assign fair value as of the acquisition date. The initial purchase accounting, including the identification and allocation of consideration to assets acquired, is not complete and the preliminary purchase price allocation is subject to further adjustment as additional information becomes available and as additional analyses and final valuations are completed. Identified intangible assets acquired and their estimated useful lives as of February 10, 2023, were (in thousands, except years): Estimated Useful Life Estimated Fair Value Developed technology - Hardware 3 $ 2,500 Developed technology - Software 5 5,100 Customer relationships 8 5,400 Intangible assets, net 5.9 $ 13,000 Developed technology relates to Velodyne’s lidar sensors and BlueCity AI software used to monitor traffic networks and public spaces. The Company valued the hardware developed technology using the relief-from-royalty method under the income approach. Software developed technology was valued using the excess earnings method. The economic useful life was determined based on the technology cycle related to each developed technology, as well as the cash flows over the forecasted period. The estimated fair value of the customer relationships was determined using the distributor method with the estimated useful life of 8 years that approximates the pattern in which the economic benefits are expected to be realized. The estimated fair value of the inventory was determined using the comparative sales method, which estimated the expected sales price of the product, reduced by all costs expected to be incurred to complete or dispose of the inventory, as well as a profit on the sale. The estimated fair value of property and equipment utilized a replacement cost method incorporating the age, quality and condition of the assets. The excess of the purchase consideration and the fair value of identifiable assets acquired and liabilities assumed at the acquisition date over the fair value of net tangible and identified intangible assets acquired was recorded as goodwill, which is not deductible for tax purposes. Goodwill is primarily attributable to the assembled workforce and the anticipated operational synergies at the time of the Velodyne Merger. The Company’s consolidated statement of operations as of June 30, 2023, includes Velodyne revenue of $13.4 million for the period from the acquisition date of February 10, 2023 to June 30, 2023. Due to the continued integration of the combined businesses, it was impractical to determine the earnings. The unaudited supplemental pro forma information below presents the combined historical results of operations of the Company and Velodyne as if the Velodyne Merger had been completed as of January 1, 2022 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Revenue $ 19,396 $ 21,836 $ 36,626 $ 36,574 Net loss $ (122,733) $ (73,053) $ (300,013) $ (177,164) The unaudited supplemental pro forma information above includes the following adjustments to net loss in the appropriate pro forma periods (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 An increase in amortization expense related to the fair value of acquired identifiable intangible assets, net of the amortization expense already reflected in actual historical results $ — $ (754) $ (277) $ (1,508) A decrease (increase) in expenses related to the transaction expenses $ — $ — $ 6,058 $ (6,058) A net increase in revenue related to the impact of the acceleration of the Amazon Warrant vesting recognized by Velodyne at the close of the Velodyne Merger transaction $ — $ — $ 3,656 $ — A decrease in expenses related to the impact of the acceleration of the Amazon Warrant vesting recognized by Velodyne at the close of the Velodyne Merger transaction $ — $ — $ 26,704 $ — Represents decrease (increase) in additional stock-based compensation expense related to Ouster employee terminations due to change in control. $ — $ — $ 6,383 $ (5,195) Represents a decrease (increase) in severance expense in connection with the Velodyne Merger transaction $ — $ — $ 10,586 (10,586) The unaudited supplemental pro forma information has been presented for illustrative purposes only and is not necessarily indicative of results of operations that would have been achieved had the Velodyne Merger taken place on the date indicated, or of the Company’s future consolidated results of operations.

Commercial paper, corporate debt and U.S. government agency securities are included within Level 2 of the fair value hierarchy because they are valued using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for the identical underlying security which may not be actively traded. The fair value of the warrant liabilities from the private placement warrants issued by CLA (“Private Placement warrants”) is based on significant unobservable inputs, which represent Level 3 measurements within the fair value hierarchy. In determining the fair value of the warrant liabilities, the Company used the Black-Scholes option pricing model to estimate the fair value using unobservable inputs including the expected term, expected volatility, risk-free interest rate and dividend yield (see Note 7). The following table presents a summary of the changes in the fair value of the Company’s Level 3 financial instruments (in thousands): Private Placement Warrant Liability Fair value as of December 31, 2022 180 Change in the fair value included in other income, net (126) Fair value as of June 30, 2023 54 Fair value as of December 31, 2021 $ 7,626 Change in the fair value included in other income, net (7,134) Fair value as of June 30, 2022 $ 492 Non-Recurring Fair Value Measurements The Company has certain assets, including goodwill and other intangible assets, which are measured at fair value on a non-recurring basis and are adjusted to fair value only if an impairment charge is recognized. The categorization of the framework used to measure fair value of the assets is considered to be within the Level 3 valuation hierarchy due to the subjective nature of the unobservable inputs used. Disclosure of Fair Values Financial instruments that are not re-measured at fair value include accounts receivable, accounts payable, accrued and other current liabilities and debt. The carrying values of these financial instruments approximate their fair values.

Cash is invested in short-term money market funds that earn interest. The Company acquired short-term investments consisting of commercial paper, corporate debt and U.S. government agency securities as a result of the merger with Velodyne that closed on February 10, 2023 (see Note 3). Short-term investments were $133.2 million as of June 30, 2023. Unrealized gains and losses on the Company’s short-term investments were not significant as of June 30, 2023 and therefore, the amortized cost of the Company’s short-term investments approximated their fair value. Restricted Cash Restricted cash consists of collateral to merchant credit card and certificates of deposit held by a bank as security for outstanding letters of credit. The Company had a restricted cash balance of $1.6 million and $1.3 million as of June 30, 2023 and December 31, 2022, respectively, which has been excluded from the Company’s cash and cash equivalents balances. The Company presented $0.5 million and $0.3 million of the total amount of restricted cash within current assets on the condensed consolidated balance sheets as of June 30, 2023 and December 31, 2022, respectively. The remaining restricted cash balance of $1.1 million and $1.1 million is included in non-current assets on the condensed consolidated balance sheets as of June 30, 2023 and December 31, 2022, respectively.

Goodwill Goodwill represents the excess of the aggregate purchase price over the fair value of net identifiable assets acquired in a business combinations. The following table displays the changes in the carrying amount of goodwill (in thousands): Goodwill Balance - December 31, 2022 $ 51,152 Goodwill addition related to Velodyne Merger 115,523 Goodwill impairment charges (166,675) Balance - June 30, 2023 $ — Goodwill is not amortized and is tested for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Since February 10, 2023, the date of the Velodyne Merger, the Company experienced a significant decline in its stock price. This decline resulted in the total market value of its shares of stock outstanding (“market capitalization”) being less than the carrying value of its reporting unit as of March 31, 2023 and June 30, 2023. The Company also considered the impact of current macroeconomic conditions in the lidar sensor industry that potentially impact the fair value of the Company’s reporting unit. The macroeconomic conditions considered include deterioration in the equity markets evidenced by sustained declines in the Company’s stock price, those of its peers, along with an increase in the weighted-average cost of capital primarily driven by an increase in interest rates. After considering all available evidence in the evaluation of goodwill impairment indicators, the Company determined it was appropriate to perform an interim quantitative assessment of its goodwill as of March 31, 2023 and June 30, 2023. In connection with the Company’s interim goodwill impairment assessments the Company recorded goodwill impairment charges of approximately $99.4 million in the three months ended March 31, 2023 and $67.3 million in the three months ended June 30, 2023. The Company’s goodwill impairment analysis included a comparison of the aggregate estimated fair value of our reporting unit to our total market capitalization. As of June 30, 2023, remaining goodwill balance was nil. No goodwill impairment charges were recognized during the year ended December 31, 2022.

The Loan Agreement provides the Company with a term loan facility of up to $50.0 million, subject to certain terms and conditions. The Company borrowed the initial tranche of $20.0 million on April 29, 2022. On October 17, 2022, the Company borrowed an additional $20.0 million. As of June 30, 2023, the Company did not achieve certain conditions relating to trailing twelve month revenue and profit milestones under the Loan Agreement therefore an additional $10.0 million is no longer available to the Company. As amended, the Loan Agreement includes a minimum liquidity financial covenant whereby the Company must maintain at least $60.0 million of cash in deposit accounts that are subject to an account control agreement in favor of Hercules. On February 10, 2023, the Company entered into the Third Amendment, which amends the Loan Agreement to (i) increase the existing debt baskets for (a) purchase money debt and capital leases and (b) letter of credit obligations, (ii) provide for increased flexibility to maintain cash in non-US accounts, and (iii) provide for increased flexibility to relocate certain equipment. Advances under the Loan Agreement bear interest at the rate of interest equal to greater of either (i) (x) the prime rate as reported in The Wall Street Journal plus (y) 6.15%, and (ii) 9.40%, subject to compliance with financial covenants and other conditions. The Loan Agreement includes covenants, limitations, and events of default customary for similar facilities. The Loan Agreement matures on May 1, 2026. In connection with the Loan Agreement, the Company paid the lender a cash facility and legal fees of $0.6 million and incurred debt issuance costs to third parties that were directly related to issuing debt in the amount of $0.3 million. The effective interest rate on this debt is 17.9% after giving effect to the debt discount, debt issuance costs and the end of term charge. Amortization expense included in the interest expense related to debt discount and debt issuance costs of the Loan Agreement was not material for the three and six months ended June 30, 2023. Interest on amounts borrowed under the Loan Agreement is payable on a monthly basis until June 1, 2025 (the “Amortization Date”). On and as of the Amortization Date, payments consist of equal monthly installments of principal and interest payable until the secured obligations are repaid in full. However, if the Company achieves certain equity proceeds, revenue or profit targets for the twelve-month period ending December 31, 2023, then the Amortization Date will be extended to the Maturity Date. The entire principal balance and all accrued but unpaid interest shall be due and payable on the Maturity Date. On the earliest to occur of May 1, 2026, the date on which the obligations under the Loan Agreement are paid and the date on which such obligations become due and payable, the Company is also required to pay Hercules an end of term fee in an amount equal to 7.45% of the aggregated amount of all Advances made under the Loan Agreement. The Company may prepay the principal of any advance made pursuant to the terms of the Term Loan Facility at any time subject to a prepayment charge equal to: 2.50%, if such advance is prepaid in any of the first 12 months following the Closing Date, 1.50%, if such advance is prepaid after 12 months but prior to 24 months following the Closing Date, and 1.0%, if such advance is prepaid anytime thereafter. As of June 30, 2023, the Company is in compliance with all financial covenants under the Loan Agreement. Long-term debt outstanding is summarized below (in thousands): June 30, Long-term debt $ 40,000 End of term fee 771 Less: unamortized debt discount (413) Less: debt issuance costs (223) Total debt $ 40,135

Equity [Abstract]
Warrants	Warrants Private Placement Warrants Simultaneously with the closing of the Company’s initial public offering (the “IPO”) in August 2020, the sponsor of CLA, Colonnade Sponsor LLC, purchased an aggregate of 600,000 Private Placement warrants at a price of $10.00 per warrant, for an aggregate purchase price of $6,000,000. The Private Placement warrants became exercisable 12 months following the closing of the Company’s IPO, and will expire 5 years from the completion of the Merger, or earlier upon redemption or liquidation. On March 11, 2021, as adjusted to reflect the Reverse Stock Split, each outstanding Private Placement warrant automatically converted into a warrant to purchase one-tenth of a share of Ouster common stock pursuant to the Warrant Agreement. Each 10 Private Placement warrants is exercisable for one share of Ouster common stock at an exercise price of $115.00 per share, with no fractional shares being issuable upon exercise of a warrant. The private placement warrant liability was remeasured to fair value as of June 30, 2023 and 2022, resulting in a gain of $0.1 million and $7.1 million for the six months ended June 30, 2023 and 2022, respectively, classified within other income, net in the condensed consolidated statements of operations and comprehensive loss. The Private Placement warrants were valued using the following assumptions under the Black-Scholes option-pricing model: December 31, 2021 June 30, 2022 December 31, 2022 June 30, 2023 Stock price $ 52.0 $ 16.2 $ 8.6 $ 4.9 Exercise price of warrant $ 115.0 $ 115.0 $ 115.0 $ 115.00 Expected term (years) 4.2 3.7 3.2 2.7 Expected volatility 57.00 % 57.98 % 70.01 % 80.00 % Risk-free interest rate 1.14 % 3.00 % 4.39 % 4.61 % Public Warrants CLA, in its IPO in August 2020, issued 2,000,000 units that each consisted of one Class A ordinary share and one-half warrant to purchase a Class A ordinary share (the “Public warrants”). The warrants became exercisable 12 months following the closing of the Company’s IPO, and will expire five years from the completion of the Merger, or earlier upon redemption or liquidation. As adjusted for the Reverse Stock Split, each 10 Public warrants is exercisable for one share of Ouster common stock at an exercise price of $115.00 per share, with no fractional shares issuable upon exercise of a warrant. The Public warrants were recognized as equity upon the Merger in the amount of $17.9 million. Prior to their expiration, the Company may redeem the Public warrants at a price of $0.10 per warrant, provided that the closing price of the Company’s common stock equals or exceeds $180.00 per share for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which the Company gives proper notice of such redemption to the warrants holders. The Company also acquired 5,973,170 outstanding public warrants upon closing the Velodyne Merger to purchase shares of the Company’s common stock (the “Velodyne Public warrants”). Each warrant entitles the holder to purchase 0.06153 shares of the Company’s common stock. Each 10 Velodyne Public warrants is exercisable for 0.6153 shares of the Company’s common stock at an exercise price of $140.20 per 0.6153 share of common stock, with no fractional shares being issuable upon exercise of a warrant. The warrants are exercisable at any time and expire in September 2025. The Company may redeem the outstanding warrants in whole and not in part at a price of $0.10 per warrant at any time after they become exercisable, provided that the last sale price of the Company’s common stock equals or exceeds $219.41 per share, subject to adjustments, for any 20-trading days within a 30-trading day period ending three business days prior to the date on which the Company sends the notice of redemption to the warrant holders. Amazon Warrant On February 10, 2023, as part of Velodyne Merger, the Company assumed a warrant agreement and a transaction agreement, pursuant to which Velodyne agreed to issue to Amazon.com NV Investment Holdings LLC, a wholly-owned subsidiary of Amazon Inc. (“Amazon”), a warrant to acquire, following customary antidilution adjustments, up to an aggregate of 3,263,898 shares of the Company’s common stock at an exercise price of $50.71 per share (the “Amazon Warrant”). The exercise price and the warrant shares issuable upon exercise of the Amazon Warrant are subject to further antidilution adjustments, including in the event we make certain sales of common stock (or securities exercisable or convertible into or exchangeable for shares of our common stock) at a price less than the exercise price of the Amazon Warrant. The Amazon Warrant is subject to vesting; 50% of the unvested Amazon Warrant vested as a result of the Velodyne Merger and the remainder will vest over time based on payments by Amazon or its affiliates to us in connection with Amazon’s purchase of goods and services from the Company. The Amazon Warrant shares vest in multiple tranches over time based on payments of up to $100.0 million by Amazon or its affiliates (directly or indirectly through third parties) to the Company in connection with Amazon’s purchase of goods and services. The vested Amazon Warrant portion, representing 1,848,694 shares of Ouster common stock with a fair value of $8.6 million, was included in the Velodyne Merger purchase price consideration on February 10, 2023. The fair value of the unvested Amazon Warrant, representing 1,415,204 unvested Ouster common stock shares with a fair value of $6.5 million, will be recognized as a non-cash stock-based reduction to revenue when Amazon makes payments and vesting conditions become probable of being achieved. The fair value of the Amazon Warrant shares was estimated on February 10, 2023, the date of completion of the Velodyne Merger, using the Black-Scholes option pricing model on the remaining contractual term of 6.98 years, an expected volatility of 53.7%, a 3.86% risk-free interest rate and a 0% expected dividend yield. The Company estimated expected volatility by using historical volatility of the Company’s publicly trading stock for the period commencing on the date of the Merger and ending February 10, 2023 and historical volatility of a group of publicly traded peer companies for the period commencing February 16, 2016 and ending on the date of the Merger. The right to exercise the Amazon Warrant and receive the warrant shares that have vested expires February 4, 2030. No additional Amazon Warrant shares vested during the three months ended June 30, 2023. As of June 30, 2023, there were 1,848,694 Amazon Warrant shares vested.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Letters of Credit In connection with certain office leasehold interests in real property located in San Francisco (350 Treat Ave and, 2741 16th Street) and in Paris, the Company obtained letters of credit from certain banks as required by the lease agreements. If the Company defaults under the terms of the applicable lease, the lessor will be entitled to draw upon the letters of credit in the amount necessary to cure the default. The amounts covered by the letters of credit are collateralized by certificates of deposit, which are included in restricted cash on the condensed consolidated balance sheets as of June 30, 2023 and December 31, 2022. The outstanding amount of the letters of credit was $1.4 million and $1.3 million as of June 30, 2023 and December 31, 2022, respectively. Non-Cancelable Purchase Commitments As of June 30, 2023, the Company had non-cancelable purchase commitments to third-party contract manufacturers for approximately $25.3 million and other vendors for approximately $4.8 million. Litigation The Company is involved in various legal proceedings arising in the ordinary course of business. The Company accrues a liability when a loss is considered probable and the amount can be reasonably estimated. Legal fees are expensed as incurred. The Company has identified certain claims as a result of which a loss may be incurred, but in the aggregate any loss is expected to be immaterial. This assessment is based on our current understanding of relevant facts and circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future. Significant judgment is required in both the determination of probability and the determination as to whether an exposure is reasonably estimable. Actual outcomes of these legal and regulatory proceedings may materially differ from our current estimates. The Company has recorded immaterial accruals with respect to the following because a loss is not considered probable or cannot be reasonably estimated: Velodyne Legacy Litigation On March 3, 2021, a purported shareholder of Velodyne filed a complaint for a putative class action against Velodyne, Anand Gopalan and Andrew Hamer in the United States District Court, Northern District of California, entitled Moradpour v. Velodyne Lidar, Inc., et al. , No. 3:21-cv01486-SI. The complaint alleged purported violations of the federal securities laws and that, among other things, the defendants made materially false and/or misleading statements and failed to disclose material facts about the Company’s business, operations and prospects, including with respect to David Hall’s role with Velodyne and removal as Chairman of Velodyne’s Board of Directors. The complaint alleged that purported class members have suffered losses and sought, among other things, an award of compensatory damages on behalf of a putative class of persons who purchased or otherwise acquired Velodyne’s securities between November 9, 2020 and February 19, 2021. On March 12, 2021, a putative class action entitled Reese v. Velodyne Lidar, Inc., et al. , No. 3:21-cv-01736-VC, was filed against Velodyne, Mr. Gopalan and Mr. Hamer in the United States District Court for the Northern District of California, based on allegations similar to those in the earlier class action and seeking recovery on behalf of the same putative class. On March 19, 2021, another putative class action entitled Nick v. Velodyne Lidar, Inc., et al. , No. 4:21-cv-01950-JST, was filed in the United States District Court for the Northern District of California, against Velodyne, Mr. Gopalan, Mr. Hamer, two current or former directors, and three other entities. The complaint was based on allegations similar to those in the earlier class actions and sought, among other things, an award of compensatory damages on behalf of a putative class of persons who purchased or otherwise acquired Velodyne’s securities between July 2, 2020 and March 17, 2021. The class actions have been consolidated, lead plaintiffs have been appointed and an amended consolidated complaint was filed on September 1, 2021, based on allegations similar to those in the earlier class actions. Velodyne filed a motion to dismiss the amended and consolidated complaint on November 1, 2021. The plaintiffs filed a first amended complaint on February 11, 2022. Velodyne filed a motion to dismiss on March 4, 2022. On July 1, 2022, the court denied the motion to dismiss as it relates to the claims related to David Hall’s role with Velodyne, but granted the motion to dismiss as to all other claims. The case is proceeding with discovery with trial set for August 4, 2025. The Company does not believe the claims are meritorious and intends to defend the actions vigorously. On March 12, 2021, a putative shareholder derivative lawsuit entitled D’Arcy v. Gopalan, et al. , No. 1:21-cv-00369-MN, was filed in the United States District Court for the District of Delaware against current and former directors and/or officers Anand Gopalan, Andrew Hamer, David S. Hall, Marta Thoma Hall, Joseph B. Culkin, Michael E. Dee, James A. Graf, Barbara Samardzich, and Christopher A. Thomas, and names Velodyne as a nominal defendant. The complaint asserted claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets against all of the individual defendants, and asserted a contribution claim under the federal securities laws against Mr. Gopalan and Mr. Hamer. On March 16, 2021, a second shareholder derivative lawsuit entitled Kondner, et al. v. Culkin, et al. , No. 1:21cv-00391-MN, was filed in the United States District Court for the District of Delaware against most of the same defendants named in the earlier derivative complaint, and asserted claims against the individual defendants for alleged breaches of fiduciary duty and waste of corporate assets. Both derivative actions are based on allegations similar to those in the class actions discussed above, and have now been consolidated. On January 3, 2022, the plaintiffs filed an amended complaint. The case is stayed pending the outcome of the Moradpour lawsuit. The Company does not believe the claims are meritorious and intends to defend the actions vigorously. On January 18, 2022, David and Marta Hall filed a lawsuit in the Superior Court of California, County of Alameda, against current and former officers and directors of Velodyne, as well as Jeff Vetter, Velodyne’s outside counsel. The Halls are seeking to recover damages for financial and other injuries they allegedly sustained as a result of the merger between Graf and Velodyne. On May 3, 2022, certain defendants filed motions to compel arbitration and other defendants filed motions to quash service of process for lack of personal jurisdiction. The court conducted a hearing on the motions on July 20, 2022. On August 30, 2022, the court granted the motion to quash service with respect the out of state defendants. On October 3, 2022, the court granted the motion to compel Mr. Hall to arbitrate his claims, and stayed proceedings on Ms. Hall’s claims pending arbitration of Mr. Hall’s claims. On October 20, 2022, David and Marta voluntarily dismissed the action without prejudice. On January 3, 2023, the Halls filed an arbitration demand with the same allegations as the prior lawsuit. The arbitrator has not yet set a schedule. The Company does not believe the claims are meritorious and intends to defend the action vigorously. On December 8, 2021, Velodyne received a subpoena for documents related to Wei Weng’s trading in stock of Graf Acquisition Corp. (Velodyne’s predecessor) stock during 2020, prior to the announcement that Velodyne was planning to merge into Graf Acquisition Corp. Velodyne has complied with the SEC’s requests to date; however, the SEC may request additional documents or information. No such follow up requests have been received to date. On December 1, 2022 and December 20, 2022, purported stockholders of Velodyne filed the following lawsuits against Velodyne and certain of its directors in the Southern District of New York for violations of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 and U.S. Securities and Exchange Commission ("SEC") Rule 14a-9 : O’Dell v. Velodyne Lidar, Inc., et al. , Civil Action No. 22-cv-10211, Carlisle v. Velodyne Lidar, Inc., et al ., Civil Action No. 22-cv-10720. On December 29, 2022, a complaint alleging generally the same claims was filed in the United States District Court for the District of Delaware, captioned Wheeler v. Velodyne Lidar, Inc., et al ., Civil Action No. 22-cv-01641-UNA. All of the lawsuits were voluntarily dismissed by the respective Plaintiffs. They have agreed to settle in principle the mootness fees and the Company has recorded a related immaterial accrual. Ouster Litigation On June 10, 2021, the Company received a letter from the SEC notifying us of an investigation and document subpoena. The subpoena seeks documents regarding projected financial information in CLA’s Form S-4 registration statement filed on December 22, 2020. The Company has complied with the SEC’s requests to date; however, the SEC may request additional documents or information. No such follow up requests have been received to date. On April 11, 2023, the Company filed a complaint with the United States International Trade Commission (the “Commission”) pursuant to 19 U.S.C. § 1337 (“Section 337”). The complaint requests that the Commission institute an investigation relating to the unlawful importation, sale for importation, and/or sale after importation into the United States by Hesai Group, Hesai Technology Co., Ltd., and Hesai Inc. (collectively “Hesai”) of certain LiDAR (Light Detection and Ranging) systems and/or components thereof. The complaint alleges that Hesai’s LiDAR products infringe certain claims of the Company’s U.S. Patent Nos. 11,175,405, 11,178,381, 11,190,750, 11,287,515 and/or 11,422,236. The complaint seeks the issuance of a permanent exclusion order and cease and desist order. On May 11, 2023, the Commission decided to institute an investigation based on the Company’s complaint as In the Matter of Certain LiDAR (Light Detection and Ranging) Systems and Components Thereof, 337-TA-1363. On May 25, 2023, the Administrative Law Judge issued a procedural schedule whereby the evidentiary hearing is set to begin on January 4, 2024, with a target date for completion of the Investigation by the Commission on October 17, 2024. On June 7, 2023, Hesai responded to the complaint and denied all allegations. On June 22, 2023, Hesai filed a motion to terminate or alternatively stay the Investigation in light of the settlement agreement signed in 2020 by Velodyne Lidar Inc. and Hesai. Ouster filed its opposition, including disputing any obligations to arbitrate as non-signatory to the 2020 agreement. This motion is pending. On April 11, 2023, the Company also filed a complaint in the District of Delaware alleging patent infringement of the same patents as in the aforestated Section 337 proceeding against Hesai Group and Hesai Technology Co., Ltd. The complaint seeks monetary damages as well as the issuance of a permanent injunction. On May 30, 2023, the Court granted stay the case pending the resolution of In the Matter of Certain LiDAR (Light Detection and Ranging) Systems and Components Thereof, 337-TA-1363. On May 17, 2023, Hesai Photonics Technology Co. Ltd. and Hesai Group (collectively “Hesai Photonics”) filed a request for arbitration with JAMS against Ouster, Inc. (“Ouster”), Velodyne Lidar, Inc., Velodyne, LLC, and Oban Merger Sub II LLC (collectively “Velodyne”). Hesai Photonics alleges that Ouster is bound by the terms and conditions, including an obligation to arbitrate disputes, of a Settlement Agreement signed in 2020 between Hesai Photonics and Velodyne as a result of Ouster’s 2023 merger with Velodyne. On June 13, 2023, Ouster and Velodyne denied all allegations and intends to defend the action vigorously. Arbitration has not set a schedule. Other than as set forth above, as of June 30, 2023 and December 31, 2022 there were no material litigation matters. Indemnification From time to time, the Company enters into agreements in the ordinary course of business that include indemnification provisions. Generally, in these provisions the Company agrees to defend, indemnify, and hold harmless the indemnified parties for claims and losses suffered or incurred by such indemnified parties for which the Company is responsible under the applicable indemnification provisions. The terms of the indemnification provisions vary depending upon negotiations between the Company and its counterpart; however, typically, these indemnification obligations survive the term of the contract and the maximum potential amount of future payments the Company could be required to make pursuant to these provisions are uncapped. To date, the Company has never incurred costs to settle claims related to these indemnification provisions.

Prior to 2023, the Company has executed or assumed as lessee other five operating leases for rental of office space. The terms of those leases range from 1 to 3 years. Since February 10, 2023, the Company also assumed long-term non-cancellable lease agreements stemming from the Velodyne Merger: (i) approximately 204,000 square feet of office and manufacturing space in San Jose, California and (ii) additional space pursuant to the assumed leases for offices located in Alameda, California; and Bengaluru, India.

Stock-based Compensation	Stock-based Compensation As of June 30, 2023, the Company has five equity incentive plans: its Amended and Restated 2015 Stock Plan (the “2015 Plan”), the Sense Photonics, Inc. 2017 Equity Incentive Plan (the “Sense Plan”), the Velodyne Lidar, Inc. 2020 Equity Incentive Plan (the “Velodyne Plan”), its 2021 Incentive Award Plan (the “2021 Plan”) and its 2022 Employee Stock Purchase Plan (the “2022 ESPP” and, collectively with the 2015 Plan, the Sense Plan, the Velodyne Plan and the 2021 Plan, the “Plans”). The Plans, other than the 2022 ESPP, provide for the grant of stock options, stock appreciation rights, restricted stock awards (“RSAs”), restricted stock units (“RSUs”), performance stock unit awards and other forms of equity compensation (collectively, “equity awards”). In addition, the 2021 Plan provides for the grant of performance bonus awards. New equity awards may only be granted under the Velodyne Plan and the 2021 Plan. Awards under the Velodyne Plan may be granted to employees, including officers, and other service providers who were not previously employed by or who did not previously provide services to the Company or a subsidiary of the Company, in each case, prior to February 10, 2023, within the limits provided in the Velodyne Plan. Awards under the 2021 Plan can also be granted to employees, including officers, directors and consultants of the Company and its subsidiaries, in each case, within the limits provided in the 2021 Plan. The Company’s 2022 ESPP has been offered to all eligible employees since August 2022 and generally permits certain employees to purchase shares of our common stock through payroll deductions of up to 15% of their compensation of each offering period, subject to certain limitations. The ESPP provides offering periods that have a duration of 24 months in length and are comprised of purchase periods of six months in length. The offering periods are scheduled to start on the first trading day on or after May 16 and November 16 of each year. Under the 2022 ESPP, the purchase price of a share under the ESPP equals 85% of the lesser of the fair market value of a share of common stock on either the first or last day of the applicable offering period or the last day of the applicable purchase period. In May 2023, the Company increased the share purchase limit under the 2022 ESPP to 3,000 shares of Company common stock per offering period and added Velodyne Lidar, Inc. as a participating employer in the 2022 ESPP. As of June 30, 2023, 0.4 million shares of the Company’s common stock were pending issuance under the 2022 ESPP. The stock-based compensation expense is calculated as of the beginning of the offering period as the fair value of the 2022 ESPP shares utilizing the Black-Scholes option valuation model and is recognized over the offering period. The first offering period under the 2022 ESPP commenced on September 6, 2022. Certain employees have the right to early exercise unvested stock options, subject to rights held by the Company to repurchase unvested shares in the event of voluntary or involuntary termination. The Company accounts for cash received in consideration for the early exercise of unvested stock options as a non-current liability, included as a component of other liabilities in the Company’s condensed consolidated balance sheets.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items arising in the quarter. The Company’s effective tax rate differs from the U.S. statutory tax rate primarily due to valuation allowances on the deferred tax assets as it is more likely than not that some, or all, of the Company’s deferred tax assets will not be realized. The Company continues to maintain a full valuation allowance against its net deferred tax assets. Due to tax losses and the offsetting valuation allowance, the income tax provision for six months ended June 30, 2023 and 2022, respectively, was not material to the Company’s condensed consolidated financial statements.

The following table presents total revenues by geographic area based on the location products were shipped to and services provided (in thousands): Three Months Ended June 30, Six months ended June 30, 2023 2022 2023 2022 Americas $ 10,931 $ 3,185 $ 20,585 $ 6,503 Asia and Pacific 2,581 2,575 5,465 4,932 Europe, Middle East and Africa 5,884 4,569 10,576 7,452 Total $ 19,396 $ 10,329 $ 36,626 $ 18,887 Revenue contract balances Timing of revenue recognition may differ from the timing of invoicing to customers. An unbilled receivable is recorded in instances when revenue is recognized prior to invoicing, and amounts collected in advance of services being provided are recorded as deferred revenue. Contract assets are generated when contractual billing schedules differ from revenue recognition timing. Unbilled receivables A receivable for multi-year licensing services is generally recorded upon invoicing. A receivable for multi-year license contracts is recorded upon delivery, whether or not invoiced, to the extent the Company has an unconditional right to receive payment in the future related to those licenses. The current portion of these unbilled receivables in the amount of $2.9 million, primarily consisting of unbilled receivables from multi-year license contracts, is included in “Accounts receivable, net” on the condensed consolidated balance sheet. Contract Assets Contract assets primarily relate to the Company’s rights to consideration under license arrangements when the licenses have been transferred to the customers, but payment is contingent upon a future event, other than the passage of time (i.e. type of unbilled receivable) and for which the Company does not have an unconditional right at the reporting date. Contract asset also arises when the timing of billing differs from the timing of revenue recognized, such as when revenue is recognized on guaranteed minimum payments at the inception of the contract when there is not yet a right to invoice in accordance with contract terms and payment is contingent upon future event. Contract Liabilities Contract liabilities consist of deferred revenue, customer advanced payments and customer deposits. Deferred revenue includes billings in excess of revenue recognized related to product sales, licenses, extended warranty and other services revenue, and is recognized as revenue when the Company performs under the contract. The long-term portion of deferred revenue, mostly related to obligations under license arrangements and extended warranty, is classified as non-current contract liabilities and is included in other non-current liabilities in the Company’s condensed consolidated balance sheets. Customer advanced payments represent required customer payments in advance of product shipments according to customer’s payment term. Customer advance payments are recognized as revenue when control of the performance obligation is transferred to the customer. Customer deposits represent consideration received from a customer which can be applied to future product or service purchases, or refunded. Contract assets and liabilities are presented net at the individual contract level in the condensed consolidated balance sheet and are classified as current or noncurrent based on the nature of the underlying contractual rights and obligations. June 30, December 31, Contract liabilities, current Deferred revenues from licensing arrangements $ 4,198 $ — Other contract liabilities 5,578 402 Contract liabilities, long-term portion Deferred revenues from licensing arrangements 1,691 — Other contract liabilities 3,573 342 Total contract liabilities $ 15,040 $ 744

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries (all of which are wholly owned) and have been prepared in conformity with U.S. generally accepted accounting principles (“US GAAP”) applicable to interim periods. All intercompany balances and transactions have been eliminated in consolidation. The presentation of certain prior period amounts has been reclassified to conform with current year presentation. The unaudited condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the results of operations for the periods shown. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2022 and the notes related thereto, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 24, 2023. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by US GAAP. Certain information and note disclosures normally included in the audited financial statements prepared in accordance with US GAAP have been condensed or omitted from this report, as is permitted by applicable rules and regulations. The results of operations for any interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future years or interim periods. On April 6, 2023, the Board of Directors approved a one-for-10 reverse stock split and a corresponding reduction in authorized shares of common stock (the “Reverse Stock Split”). On April 20, 2023, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to its Certificate of Incorporation to effect the one-for-10 Reverse Stock Split of the Company’s common stock and a corresponding reduction in authorized shares of common stock. The par value of the Company’s common stock was not adjusted as a result of the Reverse Stock Split. All share and per share amounts and related stockholders’ equity balances presented herein have been retroactively adjusted to reflect the Reverse Stock Split.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when a customer obtains control of promised products or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these products or services. To achieve the core principle of this standard, the Company performs the following five steps: 1) Identify the contract with a customer A contract with a customer exists when the contract is approved, each party’s rights regarding the product or services to be transferred and the payment terms for the product or services can be identified, it is determined that the customer has the ability and intent to pay and the contract has commercial substance. The Company applies judgement in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer. Accounts receivable are due under normal trade terms, typically three months or less. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the product or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the product or services is separately identifiable from other promises in the contract. 3) Determine the transaction price The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring product or services to the customer. Royalties from the license of IP are included in the transaction price in the period the sales occur. Other forms of variable consideration are included in the transaction price if the Company judges that it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component. All taxes assessed by a governmental authority on a specific revenue-producing transaction collected by the Company from a customer are excluded from the transaction price. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). In the three and six months ended June 30, 2023 and 2022, respectively, the Company did not have a material volume of contracts that required the allocation of transaction price to multiple performance obligations. 5) Recognize revenue when or as the Company satisfies a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to a customer. Product revenue The majority of the Company’s revenue comes from product sales of lidar sensors to direct customers and distributors. Revenue is recognized at a point in time when control of the goods is transferred to the customer, generally occurring upon shipment or delivery dependent upon the terms of the underlying contract. Product sales to certain customers may require customer acceptance due to performance acceptance criteria that is considered more than a formality. For these product sales, revenue is recognized upon the expiration of the customer acceptance period. For custom products that require engineering and development based on customer requirements, the Company recognizes revenue over time using an output method based on units of product shipped to date relative to total production units under the contract. Amounts billed to customers for shipping and handling are included in revenue, and the Company has elected to recognize the cost of shipping activities that occur after control has transferred to the customer as a fulfillment cost rather than a separate performance obligation. All related shipping costs are accrued and recognized within cost of revenue when the related revenue is recognized. Services The Company’s services revenue consists primarily of product development, validation services and providing maintenance services under our extended warranty contracts. The obligation to provide services is generally satisfied over time, with the customer simultaneously receiving and consuming the benefits as the Company satisfies its performance obligations. For product development and validation service projects, the Company bills and recognizes revenue as the services are performed. For these arrangements, control is transferred over as the Company’s inputs incurred to complete the project; therefore, revenue is recognized over the service period with the measure of progress using the input method based on labor costs incurred to total labor cost (“cost-to-cost”) as the services are provided. The revenue from the sale of extended warranties is recognized over the warranty period on a ratable basis as the Company stands ready to provide services as needed. Licenses The Company licenses rights to its IP to certain customers and collects royalties based on customer’s product sales. IP revenue recognition is dependent on the nature and terms of each agreement. The Company recognizes license revenue upon the later of (a) delivery of the IP or (b) commencement of the license term if there are no substantive future obligations to perform under the arrangement. Revenue for licenses to future technology developed on a when-and-if -available basis is recognized straight-line over the license period as long as customers continue to have access to the future technology. Royalties from the license of IP are recognized at the later of the period the sales occur or the satisfaction of the performance obligation to which some or all of the royalties have been allocated. Product Warranties The Company provides standard product warranties for a term of typically one two Costs to obtain a contract The Company expenses the incremental costs of obtaining a contract when incurred because the amortization period for these costs would be less than one year. These costs primarily relate to sales commissions and are expensed as incurred in sales and marketing expense in the Company’s consolidated statements of operations and comprehensive loss. Remaining performance obligations
Investments	Investments The Company considers investments with an original maturity greater than three months and remaining maturities less than one year to be short-term investments. The Company classifies those investments that are not required for use in current operations and that mature in more than 12 months as long-term investments. The Company classifies its investments as available for sale and reports them at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. For investments sold prior to maturity, the cost of investments sold is based on the specific identification method. Realized gains and losses on the sale of investments are recorded in other income, net in the condensed consolidated statement of operations.
Amazon Warrant	Amazon Warrant The Amazon Warrant (as defined in Note 7) is accounted for as an equity instrument. To determine the fair value of the Amazon Warrant on its issuance date, the Company used the Black-Scholes option pricing model. For awards granted to a customer, which are not in exchange for distinct goods or services, the fair value of the awards earned based on service or performance conditions is recorded as a reduction of the transaction price. Accordingly, when Amazon purchases goods or services and vesting conditions become probable of being achieved, the Company records a non-cash stock-based reduction to revenue associated with the Amazon Warrant, which is calculated based on the fair value of the Amazon Warrant shares as of the Velodyne Merger date.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted The Company considers the applicability and impact of all ASUs. ASUs not referenced below were assessed and determined to be either not applicable or are not expected to have a material impact on the Company’s condensed consolidated financial statements.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, restricted cash, short-term investments and accounts receivable. Cash, cash equivalents, restricted cash and short-term investments are deposited with federally insured commercial banks. At times, cash balances in the U.S. may be in excess of federal insurance limits. As of June 30, 2023 and December 31, 2022, the Company had cash, cash equivalents and restricted cash with financial institutions in the U.S. of $89.8 million and $123.5 million, respectively. As of June 30, 2023 and December 31, 2022, the Company also had cash on deposit with financial institutions in countries other than the U.S. of approximately $3.2 million and $0.8 million, respectively, that was not federally insured. The Company generally does not require collateral or other security deposits for accounts receivable.
