Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Note 1. Description of Business and Summary of Significant Accounting Policies Description of Business Cepton, Inc., and its wholly owned subsidiaries, (collectively the “Company”) formerly known as Growth Capital Acquisition Corp. (“GCAC”), was originally incorporated in Delaware on January 4, 2010, as a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or other similar business combination with one or more target businesses. On February 2, 2021, the Company consummated its initial public offering (the “IPO”), following which its shares began trading on the Nasdaq National Market (“Nasdaq”). On August 4, 2021, GCAC entered into a Business Combination Agreement (as amended, the “Merger Agreement”) with Cepton Technologies, Inc. (“Legacy Cepton”) and GCAC Merger Sub Inc., a wholly owned subsidiary of GCAC (“Merger Sub”). On February 10, 2022 (the “Closing Date”), the transactions contemplated by the Merger Agreement (the “Business Combination”) were consummated. In connection with the closing of the Business Combination, GCAC changed its name to Cepton, Inc. and its shares and public warrants began trading on the Nasdaq under the symbols “CPTN” and “CPTNW”, respectively. As a result of the Business Combination, Cepton, Inc. became the owner, directly or indirectly, of all of the equity interests of Legacy Cepton and its subsidiaries. The Company provides state-of-the-art, intelligent, lidar-based solutions for a range of markets such as automotive, smart cities, smart spaces, and smart industrial applications. The Company’s patented Micro Motion Technology (“MMT®”)-based lidar technology enables reliable, scalable, and cost-effective solutions that deliver long range, high resolution 3D perception for smart applications. The Company is headquartered in San Jose, California, USA, with a presence in Germany, Canada, Japan, China, and India. Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The condensed consolidated financial statements include the accounts of our wholly owned subsidiaries in Canada, Germany, and the United Kingdom. All intercompany balances and transactions have been eliminated in consolidation. The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. As of March 31, 2022, the Company had cash and cash equivalents of $24.6 million, short-term investment of $20.2 million, and an accumulated deficit of $54.2 million. During the three months ended March 31, 2022, the Company incurred an operating loss of $15.6 million and had negative cash flows from operating activities of $19.5 million. Although much of the negative cash flow resulted from an increase in expenses for research and development projects and expenses for preparing to become a publicly traded company, the Company expects to continue to invest in research and development and generate operating losses in the future. The Company is subject to risks and uncertainties frequently encountered by early-stage companies including, but not limited to, the uncertainty of successfully developing its products, securing certain contracts, building its customer base, successfully executing its business and marketing strategy and hiring appropriate personnel. To date, the Company has been funded primarily by equity financings, convertible promissory notes and other borrowings. Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, or secure additional funding may require the Company to modify, delay, or abandon some of its planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on the Company’s business, operating results, financial condition, and ability to achieve its intended business objectives. Concentration of Risk Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. The Company maintains a substantial portion of its cash and cash equivalents and short-term investments in money market funds, commercial paper, corporate debt securities, and asset backed securities. Management believes that the financial institutions that hold its cash, cash equivalents, and short-term investments are financially sound and, accordingly, represent minimal credit risk. Deposits held with banks may exceed the amount of federal insurance limits provided on such deposits. As of March 31, 2022 and December 31, 2021, three customers as of each period accounted for more than 10% of accounts receivable. Customers with revenue equal to or greater than 10% of total revenue for the periods indicated were as follows: Three Months Ended 2022 2021 Customer A 30 % 30 % Customer B 20 % 13 % Customer C — % 13 % Customer D — % 21 % Customer E — % 12 % Customer F 27 % — % Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include, but are not limited to, estimating the stand-alone selling prices of performance obligations for revenue recognition, allowances for doubtful accounts, inventory valuation and reserves, valuation allowance for deferred tax assets, share-based compensation including the fair value of the Company's common stock, useful lives of property and equipment, income tax uncertainties, the valuation of certain derivative liabilities, and other loss contingencies. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates, and such differences could be material to the Company's condensed consolidated financial condition and results of operations. Product Warranties The Company typically provides a one-year warranty on its products. Estimated future warranty costs are accrued and charged to cost of goods sold in the period that the related revenue is recognized. These estimates are derived from historical data and trends of product reliability and costs of repairing and replacing defective products. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Through March 31, 2022, there were immaterial changes to the accrued warranty liability which was recorded in accrued expenses and other current liabilities on the consolidated balance sheet. Recently Adopted Accounting Pronouncements In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Topic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity In December 2019, the FASB issued ASU 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-02, Leases Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments

Business Combinations [Abstract]
Business Combination	Note 2. Business Combination The Business Combination was accounted for as a reverse recapitalization as Legacy Cepton was determined to be the accounting acquirer under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 805, Business Combinations (ASC 805). The determination is primarily based on the evaluation of the following facts and circumstances: ● the equity holders of Legacy Cepton hold the majority of voting rights in the Company; ● the board of directors of Legacy Cepton represent a majority of the members of the board of directors of the Company or were appointed by Legacy Cepton; ● the senior management of Legacy Cepton became the senior management of the Company; and ● the operations of Legacy Cepton comprise the ongoing operations of the Company. In connection with the Business Combination, outstanding capital stock of Legacy Cepton was converted into common stock of Legacy Cepton and then subsequently converted into Class A common stock of the Company, representing a recapitalization, and the net assets of the Company were acquired at historical cost, with no goodwill or intangible assets recorded. Legacy Cepton was deemed to be the predecessor of the Company, and the consolidated assets and liabilities and results of operations prior to the Closing Date are those of Legacy Cepton. The shares and corresponding capital amounts and net loss per share available to common stockholders, prior to the Business Combination, have been retroactively restated as shares reflecting the Exchange Ratio (defined below). Operations prior to the Business Combination will be those of Legacy Cepton in future reports of the combined entity. Recapitalization In connection with the Business Combination, the following occurred to recapitalize the Company: ● Shares of Legacy Cepton convertible preferred stock, Class F stock, and common stock issued and outstanding, were converted into common stock of Legacy Cepton and such shares of Legacy Cepton common stock were subsequently converted into the Company’s Class A common stock, par value $0.0001 per share, at a rate of approximately 2.449 (the “Exchange Ratio”); ● Vested stock options to purchase or receive shares of Legacy Cepton common stock (see Note 12) converted into options to purchase or receive shares of the Company’s Class A common stock, par value $0.0001 per share, in accordance with the Exchange Ratio; ● Outstanding warrants, whether vested or unvested, to purchase shares of Legacy Cepton common stock (see Note 14) converted into shares of the Company’s Class A common stock, par value $0.0001 per share, in accordance with the Exchange Ratio; ● Outstanding unvested stock options to purchase or receive shares of Legacy Cepton common stock (see Note 12) converted into stock options to purchase or receive shares of the Company’s Class A common stock upon the same terms and conditions that were in effect with respect to such stock options and restricted stock units immediately prior to the Business Combination, after giving effect to the Exchange Ratio; ● The Company’s certificate of incorporation was amended and restated to, among other things, increase the total number of authorized shares of capital stock to 355,000,000 shares, of which 350,000,000 shares were designated common stock, $0.00001 par value per share, and of which 5,000,000 shares were designated preferred stock, $0.00001 par value per share and to reclassify each share of Class A common stock and Class B common stock into one share of common stock. PIPE Investment Contemporaneously with the execution of the Merger Agreement, GCAC entered into subscription agreements (the “Subscription Agreements”) with certain investors (the “PIPE Investors”), pursuant to which the PIPE Investors agreed to purchase an aggregate of 5,950,000 shares of common stock at a purchase price of $10.00 per share, or an aggregate purchase price of $59.5 million (the “PIPE Investment”). Redemption Prior to the closing of the Business Combination, certain GCAC public shareholders exercised their right to redeem certain of their outstanding shares for cash, resulting in the redemption of 15,589,540 shares of GCAC Class A common stock for an aggregate payment of $155.9 million. Public and Private Placement Warrants GCAC warrants issued in connection with the IPO (“Public Warrants”) and in connection with the private placement units held by the Sponsor (“Private Placement Warrants”) remained outstanding after the closing of the Business Combination. The warrants became exercisable to purchase shares of the Company’s common stock at an exercise price of $11.50 per share 30 days after the completion of the Business Combination, subject to other conditions, including with respect to the effectiveness of a registration statement covering the shares of common stock underlying such warrants, and will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. The Public Warrants are equity-classified and were valued based on the instruments’ publicly listed trading price as of the Closing Date. The Private Placement Warrants are liability-classified and are valued on a recurring basis with changes in fair value recognized as a gain or loss upon remeasurement (see Note 14). Transaction Costs The Company incurred direct and incremental costs of approximately $31.6 million in connection with the Business Combination and the related equity issuance, consisting primarily of investment banking, legal, accounting, and other professional fees, which were recorded to additional paid-in capital as a reduction of proceeds. An approximate additional $2.6 million of transaction costs were recorded in general and administrative expense related to the liability classified instruments assumed subsequent to the Business Combination. Lastly, the Company recognized approximately $4.4 million and $1.9 million of prepaid director and officer insurance in prepaid expenses and other current assets and other long-term assets, respectively, in the condensed consolidated balance sheet. Transaction Proceeds Upon closing of the Business Combination, the Company received gross proceeds of $76.1 million from the Business Combination and PIPE Investment, offset by total transaction costs of $40.5 million. The following table reconciles the elements of the Business Combination to the condensed consolidated statements of cash flows and the condensed consolidated statement of changes in stockholders’ equity (deficit) for the period ended March 31, 2022 (in thousands): Cash – Trust and cash, net of redemptions $ 16,607 Cash – PIPE Investment 59,499 Gross Proceeds from the Business Combination 76,106 Less: transaction costs and advisory fees, paid (30,670 ) Net proceeds from the Business Combination 45,436 Less: transaction costs and advisory fees, accrued (900 ) Less: Private Placement Warrants assumed (2,588 ) Less: Earnout liability assumed (74,998 ) Reverse recapitalization, net $ (33,050 ) Add: Private Placement Warrants assumed 2,588 Add: Earnout liability assumed 74,998 Add: Transaction costs recorded to general and administrative expense 2,633 Add: Transaction costs accrued 900 Business Combination proceeds, net 48,069 The number of shares of common stock issued immediately following the consummation of the Business Combination were: GCAC Class A common stock, outstanding prior to Business Combination 17,250,000 Less: Redemption of GCAC Class A common stock (15,589,540 ) Class A common stock of GCAC 1,660,460 GCAC founder shares 4,312,500 GCAC shares issued in PIPE Investment 5,950,000 Business Combination and PIPE shares 11,922,960 Legacy Cepton shares 142,075,043 Class A common stock immediately after Business Combination 153,998,003 The number of Legacy Cepton shares was determined as follows: Legacy Cepton shares Legacy Cepton shares, after Exchange Ratio Balance at December 31, 2021 27,618,907 67,645,189 Convertible preferred stock 21,671,491 53,078,571 Class F stock 8,372,143 20,505,344 Option exercises 1 259,348 635,204 Warrants exercises 2 86,041 210,735 Total 142,075,043 1 – Option exercises during the period of January 1, 2022 to February 10, 2022. 2 – Represents warrants that were net exercised prior to the Business Combination (See Note 14).

Short-term investments consist of investment securities with original maturities greater than three months but less than twelve months and are included as current assets in the condensed consolidated balance sheets. For corporate debt securities, the fair value as of March 31, 2022 and December 31, 2021 approximates amortized cost basis. Because the transfer of Private Placement Warrants to non-permitted transferees would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Placement Warrant is consistent with that of a Public Warrant. Accordingly, the Private Placement Warrants are classified as Level 2 financial instruments. The value of the earnout liability is classified as Level 3 under the fair value hierarchy because it has been valued based on significant inputs not observable in the market.

(“Trinity”) to borrow up to $25.0 million through July 1, 2022 at a rate of 10.75%. The loan has a maturity date of February 1, 2026. In connection with the Trinity Loan Agreement, Legacy Cepton issued a warrant to purchase 96,998 shares of common stock with an exercise price of $16.89 per share (see Note 14). Legacy Cepton accounted for the issuance of the warrant as a commitment fee asset recorded in other current assets in the condensed consolidated balance sheet. The fair value of the warrant was estimated to be $1.3 million on the date of issuance. On January 4, 2022, Legacy Cepton borrowed $10.0 million under the agreement, incurring $0.3 million in transaction costs which were accounted for as a debt discount. Legacy Cepton also recognized a pro rata portion of the warrant fair value as a debt discount related to the $10.0 million loan. Amortization of debt discounts, in accordance with the effective interest method, are recorded as interest expense in the accompanying condensed consolidated statement of operations and comprehensive income (loss). Obligations under the Trinity Loan Agreement are secured by interest in substantially all of the Company’s assets. The agreement contains customary affirmative and negative covenants. For the three months ended March 31, 2022, the Company recognized $709 thousand in interest expense in connection with the borrowings under the Trinity Loan Agreement.

Convertible Preferred Stock As discussed in Note 2, the Company has retroactively adjusted the shares issued and outstanding prior to February 10, 2022 to give effect to the Exchange Ratio to determine the number of shares of common stock into which they were converted. Prior to the Business Combination, Legacy Cepton had shares of $0.00001 par value Series A, Series B, Series B-1, and Series C preferred stock outstanding, all of which were convertible into shares of common stock of Legacy Cepton on a 1:1 basis, subject to certain anti-dilution protections.

Stockholders' Equity Note [Abstract]
Stockholders’ Equity (Deficit)	Note 11. Stockholders’ Equity (Deficit) Common Stock Holders of common stock were entitled to one vote per share, and to receive dividends when, as and if declared by the board of directors, and, upon liquidation or dissolution, were entitled to receive all assets available for distribution to stockholders. The holders had no preemptive or other subscription rights and there were no redemption or sinking fund provisions with respect to such shares. Upon the closing of the Business Combination, the 27,618,907 shares of Legacy Cepton common stock issued and outstanding were converted into 67,645,189 shares of Class A common stock at the Exchange Ratio. As of March 31, 2022, the Company had authorized 350,000,000 shares of common stock, each with a par value of $0.00001. As of March 31, 2022, there were 153,971,462 shares of common stock issued and outstanding. Lincoln Park Transaction On November 24, 2021, Legacy Cepton entered into a Purchase Agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park” or “LPC”), pursuant to which Lincoln Park has agreed to purchase up to $100.0 million of common stock (subject to certain limitations contained in the Purchase Agreement) from time to time over a 36-month period (the “Purchase Agreement” or “Purchased Shares”) after the consummation of the Business Combination and certain other conditions set forth in the Purchase Agreement. The Company may, from time to time and at its sole discretion, direct Lincoln Park to purchase Class A common stock in accordance with daily dollar thresholds as determined within the Purchase Agreement. The purchase price per share for Class A common stock will be the lower of: (i) the lowest trading price for shares of Class A common stock on the market in which it is listed, on the applicable Purchase Date and (ii) the average of the three (3) lowest closing sale price for Class A common stock during the ten (10) consecutive business days ending on the business day immediately preceding such Purchase Date. In consideration for entering into the Purchase Agreement, the Company issued 50,000 shares of Class A common stock to Lincoln Park as a commitment fee on the date of the closing of the Business Combination. The Company is obligated to issue up to an additional 150,000 shares of Class A common stock as a commitment fee 180 days after the date of the closing of the Business Combination (collectively, the “Commitment Shares”). The issuance date fair market value for the 200,000 shares is recorded as a deferred issuance cost asset which will be ratably charged against paid-in capital upon future proceeds from the sale of common stock under the Purchase agreement. The fair market value of the share issuances was derived using the $7.99 per share closing price of Class A common stock on February 10, 2022. The fair market value of the 200,000 shares issuable upon Closing is offset within paid-in capital. As of March 31, 2022, no shares of Class A common stock were sold to Lincoln Park under the Purchase Agreement. Class F Stock Holders of Legacy Cepton’s Class F stock were entitled to the same voting rights as the equivalent number of common stock on an as-converted basis, and to receive dividends when, as and if declared by the board of directors. The holders had conversion rights for conversion into shares of common stock and preferred stock. The holders were subject to vesting terms wherein each holder acquired a vested interest in the stock over a service period of four years Upon the closing of the Business Combination, the 8,372,143 shares of Legacy Cepton Class F stock issued and outstanding were converted into 8,372,143 shares of common stock of Legacy Cepton and then subsequently converted into 20,505,344 shares of Class A common stock of the Company at the Exchange Ratio.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Note 12. Stock-Based Compensation Equity Incentive Plans On July 5, 2016, Legacy Cepton adopted the 2016 Stock Plan (the “2016 Plan”) under which 4,800,000 shares of Legacy Cepton’s common stock were reserved for issuance to employees, nonemployee directors, consultants, and advisors. As of March 31, 2022 and December 31, 2021, there were 9,187,533 shares of common stock reserved for issuance. As of March 31, 2022, there were no shares available for future issuance. At December 31, 2021, 1,472,512 shares were available for future issuance, respectively. As a result of the Business Combination, the Company will no longer grant new incentive awards under the 2016 Plan. Incentive awards existing under the 2016 Plan immediately prior to the Business Combination were converted into options to receive shares of Class A common stock through application of the Exchange Ratio (“Post Conversion Awards”). On February 10, 2022, the Company adopted the 2022 Stock Plan (the “2022 Plan”) under which 15,123,142 shares of the Company’s Class A common stock were reserved for issuance to employees, nonemployee directors, consultants, and advisors. Per the terms of the 2022 Plan, in the event any Post Conversion Awards issued and outstanding under the 2016 Plan are cancelled, terminated, or expire, said number of shares will be made available for issuance under the 2022 Plan. The share limit shall automatically increase on the first trading day in January of every calendar year during the term of the 2022 Plan, by an amount equal to the lesser of (i) two percent (2%) of the total number of shares of common stock issued and outstanding on December 31 of the immediately preceding calendar year or (ii) such number of shares of common stock as may be established by the board of directors. Restricted Common Stock Awards Unvested early exercise options or SARs are considered restricted shares and are subject to repurchase by the Company in the event the shareholders’ employment is terminated. The Company may, at its option, repurchase said shares at the lesser of (i) the price paid by the shareholder to exercise the award or (ii) the fair market value of the Company’s common stock determined on the date of the repurchase. During the vesting term, holders of restricted stock awards are deemed to be a common stock shareholder and have dividend and voting rights. On August 20, 2020, Legacy Cepton granted 150,000 early exercise option awards under the 2016 Plan to an independent contractor. The options vest over 24 equal monthly installments beginning on August 10, 2020. On December 29, 2020, the option holder elected to early exercise all granted awards, purchasing the related shares for $2.02 per share or aggregate consideration of $303 thousand. At the time of exercise, 25,000 shares were fully vested with the remainder being unvested. On the date of purchase, Legacy Cepton recognized the vested portion purchased as common stock issued with additional paid in capital. The Company recognized a liability associated with the unvested restricted shares, recording a liability included in accrued expenses of $63 thousand and $101 thousand as of March 31, 2022 and December 31, 2021, respectively. As shares of restricted stock vest, the Company will reclassify the liability to common stock and additional paid in capital. The Company did not grant any early exercise options during the three months ended March 31, 2022 and 2021. As of March 31, 2022, the Company had not repurchased any of the unvested restricted shares. The fair value of Legacy Cepton’s common stock on the date the early exercise options were granted was $2.02 per share. The fair value of Legacy Cepton’s common stock on the date the restricted shares were issued was $3.07 per share. The total intrinsic value of outstanding unvested restricted stock awards was $297,000 as of March 31, 2022.

As of March 31, 2022, there was $14.1 million of unrecognized stock-based compensation related to unvested stock options expected to be recognized over a weighted-average period of 2.54 years. The total intrinsic value of options exercised during the three months ended March 31, 2022 and 2021 was $4.6 million and $0.5 million, respectively. The Company recognizes forfeitures as they occur.

Disclosure Of Earnout Liability [Abstract]
Earnout Liability	Note 13. Earnout Liability In addition to the shares issued upon closing of the Business Combination (see Note 2), additional contingent shares (“Earnout Shares”) are payable to each holder of common stock and/or options receiving consideration in the Business Combination, in the amounts set forth below: (a) If the closing share price of Class A common stock equals or exceeds $15.00 per share for any 20 trading days within any consecutive 30-trading day period that occurs after the Closing Date and on or prior to the three-year anniversary of the Closing Date, then, the Company will issue to each holder of common stock that is entitled to Earnout Shares a number of shares of Class A common stock equal to such holder’s pro rata portion of 7,000,000 shares. (b) If the closing share price of Class A common stock equals or exceeds $17.50 per share for any 20 trading days within any consecutive 30-trading day period that occurs after the Closing Date and on or prior to the three-year anniversary of the Closing Date, the Company will issue to each holder of common stock that is entitled to Earnout Shares a number of shares of Class A common stock equal to such holder’s pro rata portion of 6,000,000 shares. The Company concluded the Earnout Shares meet the criteria for liability classification due to the existence of contingent settlement provisions that could result in holders receiving differing amounts of shares depending on the Company’s stock price or the price paid in a change of control. Because the settlement is not solely determined by the share price of the Company (that is, the share price observed in or implied by a qualifying change-in-control event), but also by the occurrence of a qualifying change-in-control event, this causes the Earnout Shares to not be indexed to the Company’s own shares, resulting in liability classification. Upon the closing of the Business Combination, the Company recorded these instruments as liabilities on the condensed consolidated balance sheet at fair value and will recognize subsequent changes in fair value in earnings at each reporting date. The following table summarizes the assumptions used in estimating the fair value of the earnout liability at each of the relevant periods: March 31, February 10, Current stock price $ 3.88 $ 7.99 Expected volatility 70.0 % 77.5 % Risk-free interest rate 2.44 % 1.80 % Expected term 2.9 years 3.0 years Expected dividend yield 0 % 0 % Current stock price: Expected volatility: Risk-free interest rate: is based on the U.S. Treasury yield curve in effect at the time of issuance for zero-coupon U.S. Treasury notes with maturities corresponding to the expected three-year term of the earnout period. Expected term: Expected dividend yield: zero At March 31, 2022, the balance of the earnout liability was approximately $18.3 million. A gain of $56.7 million was recorded in the condensed consolidated statement of operations and comprehensive income (loss) for the change in fair value of the liability.

Warrants

Warrants [Abstract]
Warrants	Note 14. Warrants Common Stock Warrants Assumed in Business Combination As part of GCAC’s initial public offering, 8,625,000 Public Warrants were sold. The Public Warrants allow the holder to purchase one share of common stock at a price of $11.50 per share, subject to adjustments. The Public Warrants may be exercised only for a whole number of shares of common stock. Each warrant is exercisable beginning 30 days after the completion of the Business Combination. The Public Warrants will expire five years after the completion of the Business Combination, or earlier upon redemption or liquidation. The Public Warrants are listed on the Nasdaq under the symbol “CPTNW”. The Company may redeem the Public Warrants when exercisable, in whole and not in part, at a price of $0.01 per warrant, so long as the Company provides not less than 30 days’ prior written notice of redemption to each warrant holder, and only if the reported last sale of common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date the Company sends the notice of redemption to the warrant holders. Simultaneously with GCAC’s initial public offering, GCAC consummated a private placement of 5,175,000 Private Placement Warrants with the Sponsor. The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of common stock issuable upon exercise will not be transferable, assignable or salable until 30 days after the completion of the Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants are non-redeemable so long as they are held by the initial purchasers or such purchaser’s permitted transferees. If the Private Placement Warrants are held by someone other than the initial stockholders or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company concluded the Private Placement Warrants meet the criteria for liability classification due to the existence of a settlement provision that adjusts the settlement amount based on who the holder of the warrant is (i.e., permitted vs. non-permitted transferees). This provision causes the Private Placement Warrants to not be indexed to the Company’s own shares, resulting in liability classification. Upon consummation of the Business Combination, the fair value of the Private Placement Warrants was recorded at a value of approximately $2.6 million. The fair value of the Private Placement Warrants was remeasured on March 31, 2022 at $2.5 million, resulting in an immaterial gain recorded in the condensed consolidated statement of operations and comprehensive income (loss). Common Stock Warrants Issued with Borrowings In August 2019, Legacy Cepton entered into a loan and security agreement (“2019 Loan Agreement”) with Silicon Valley Bank (“SVB”) that allowed for borrowings of up to $5.0 million under a term loan through July 31, 2020. In connection with the 2019 Loan Agreement, Legacy Cepton issued detachable warrants to purchase an aggregate of 60,000 shares of common stock. The term loan was repaid in February 2020. The warrant was recorded to additional paid-in capital at an estimated fair value of $88 thousand as determined by the Black-Scholes valuation model. Immediately prior to the consummation of the Business Combination, the 60,000 warrants were net exercised and subsequently converted into 136,994 shares of Class A common stock. On January 4, 2022, in connection with the Trinity Loan Agreement, the Legacy Cepton issued a warrant to purchase 96,998 shares of common stock with an exercise price of $16.89 per share. The warrant was immediately exercisable and expires on January 4, 2032. The company concluded the warrant meets the criteria for liability classification due to the existence of contingent settlement provisions that could result in holders receiving differing amounts of shares depending on the Company’s stock price or the price paid in a change of control. Because the settlement is not solely determined by the share price of the Company (that is, the share price observed in or implied by a qualifying change-in-control event), but also by the occurrence of a qualifying change-in-control event, this causes the warrant to not be indexed to the Company’s own shares, resulting in liability classification. The fair value of the warrant was initially estimated to be $1.3 million using the Black-Scholes valuation model. Immediately prior to the consummation of the Business Combination, the 96,988 warrants were net exercised and subsequently converted into 73,741 shares of Class A common stock.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 15. Income Taxes The Company’s provision for income taxes was $4 thousand and $9 thousand for the three months ended March 31, 2022 and 2021, respectively. The Company’s income tax provision for the three months ended March 31, 2022, was primarily related to income taxes on earnings from its foreign tax jurisdictions. The difference between the Company’s effective income tax rate and the U.S. federal statutory rate is primarily attributable to unrecognized U.S. federal and state tax benefit because of full valuation allowance the Company has established against its federal and state deferred tax assets and foreign tax rate differential from U.S. federal statutory rate. The quarterly fair value adjustment to the earnout liability has no impact to U.S. federal and state net operating loss. The company continues to maintain a full valuation allowance against the U.S. federal and state deferred tax assets. The Company conducts its business globally and its operating income is subject to varying rates of tax in the U.S., Canada, Germany, Hong Kong, and the U.K. Consequently, the Company’s effective tax rate is dependent upon the geographic distribution of its earnings or losses and the tax laws and regulations in each geographical region. Due to historical losses in the U.S., the Company has a full valuation allowance on its U.S. federal and state deferred tax assets. Management continues to evaluate the realizability of deferred tax assets and the related valuation allowance. If management’s assessment of the deferred tax assets or the corresponding valuation allowance were to change, the Company would record the related adjustment to income during the period in which management makes the determination. The Company is subject to income taxes in the U.S. federal, state, and various foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. All of the Company’s tax years will remain open for examination by the federal and state tax authorities for three and four years, respectively, from the date of utilization of the net operating loss or R&D Credits. The Company does not have any tax audits or other issues pending.

ASU 2016-02 Transition [Abstract]
Schedule of weighted average remaining term and discount rates	Note 16. Leases The Company leases office and manufacturing facilities under non-cancelable operating leases expiring in January 2023. The Company’s lease agreements do not contain any material terms and conditions of residual value guarantees or material restrictive covenants. The Company adopted ASC 842 using the modified retrospective method on January 1, 2022. The most significant impact of the adoption of ASC 842 was the recognition of right-of-use, or ROU, assets and lease liabilities for operating leases of $1.4 million and $1.8 million, respectively, and a reversal of deferred rent of $0.4 million on January 1, 2022. The adoption of ASC 842 did not have any impact on the Company’s operating results or cash flows. The Company determines if an arrangement is or contains a lease at inception. Operating leases are included in operating lease right-of use assets and operating lease liabilities in the Company’s condensed consolidated balance sheets. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the commencement date based on an amount equal to the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate; therefore, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company uses the implicit rate when it is readily determinable. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward existing lease classification and to exclude leases with original terms of one year or less. Further, the Company elected to combine lease and non-lease components for all asset classes. Variable lease payments are defined as payments made for the right to use an asset that vary because of changes in facts or circumstances occurring after the commencement date, other than the passage of time. Any variable lease components are expensed as incurred. The operating lease right-of-use assets also include adjustments related to prepaid or deferred lease payments and lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. The components of lease expense for the three months ended March 31, 2022 were as follows (in thousands): Amount Operating lease cost $ 364 Variable lease cost 210 Total operating lease cost $ 574 Supplemental cash flow information for the three months ended March 31, 2022 related to leases was as follows (in thousands): Amount Cash paid for amounts included in the measurement of lease liabilities: Cash paid for operating leases included in operating activities $ 442 Right of use assets obtained in exchange for lease obligations: Operating leases $ 1,448 Supplemental balance sheet information related to leases was as follows (in thousands): Amount Operating lease right-of-use assets $ 1,138 Operating lease liabilities: Operating lease liabilities, current 1,433 Operating lease liabilities, non-current — Total operating lease liabilities $ 1,433 Weighted average remaining term and discount rates were as follows (term in years): Amount Weighted average remaining lease term 0.83 Weighted average discount rate 13.66 % Maturities of lease liabilities were as follows (in thousands) Year Ending December 31, 2022 $ 1,355 2023 152 Total undiscounted lease payments $ 1,507 Present value adjustment for minimum lease commitments 74 Net Lease Liabilities $ 1,433

Commitments and Contingencies	Note 17. Commitments and Contingencies Legal Proceedings From time to time, the Company may be involved in various legal claims and litigation that arise in the normal course of its operations. The Company is defending all current litigation matters. Although there can be no assurances and the outcome of these matters is currently not determinable, the Company currently believes that none of these claims or proceedings are likely to have a material adverse effect on the Company's financial position. The Company records accruals for our outstanding legal proceedings, investigations or claims when it is probable that a liability will be incurred, and the amount of loss can be reasonably estimated. The Company evaluated developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. The Company has not recorded any accrual for loss contingencies associated with such legal claims or litigation discussed above.

Earnings Per Share [Abstract]
Basic and Diluted Net Income (Loss) Per Share	Note 19. Basic and Diluted Net Income (Loss) Per Share The Company follows the two-class method when computing net income (loss) per common share when shares are issued that meet the definition of participating securities. The Company was in a net income position for the three-months ended March 31, 2022 and a net loss position for the three-months ended March 31, 2021. The Company considers its convertible preferred stock to be participating as holders of such securities have non-forfeitable dividend rights in the event of the declaration of a dividend for shares of common stock. When the Company is in a net loss position, the net loss attributable to common stockholders is not allocated to the convertible preferred stock under the two-class method as these securities do not have a contractual obligation to share in losses. Basic net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of the Company’s common stock outstanding. During the periods when there is a net loss attributable to common stockholders, potentially dilutive common stock equivalents have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive. Net income (loss) per share calculations for all periods prior to the Business Combination have been retroactively restated to the equivalent number of shares reflecting the Exchange Ratio. The following tables present reconciliations denominators of basic and diluted net income (loss) per share: Three Months Ended 2022 2021 Denominator: Weighted-average common shares outstanding – Basic 1 115,865,890 66,735,026 Stock options to purchase common stock 2 11,216,533 — Weighted-average common shares outstanding - Diluted 127,082,423 66,735,026 1 – Includes 150,000 shares of common stock issuable to Lincoln Park in connection with the Purchase Agreement as the shares are issuable for no consideration and will be issued solely as a result of the passage of time. 2 – Includes the weighted-average unvested shares subject to repurchase of 71,619 as of the three months ended March 31, 2022. The following common stock equivalents were excluded from the computation of diluted net income (loss) per share for the periods presented because including them would have been antidilutive: Three Months Ended 2022 2021 Stock options to purchase common stock 802,866 13,224,577 Unvested restricted stock — 260,231 Preferred shares on an as-converted basis — 53,078,571 Class F shares an as-converted basis — 20,505,344 Shares issuable upon exercise of warrants — 146,954 Total 802,866 87,215,677 As of March 31, 2022, 13,000,000 Earnout Shares were excluded from the table above because the shares are considered contingently issuable and the required common share price milestones were not achieved as of March 31, 2022. As of March 31, 2022, warrants for 13,800,000 shares of common stock were excluded from the table above as no shares were issuable under the treasury stock method of computing diluted earnings per share.

Accounting Policies [Abstract]
Description of Business	Description of Business Cepton, Inc., and its wholly owned subsidiaries, (collectively the “Company”) formerly known as Growth Capital Acquisition Corp. (“GCAC”), was originally incorporated in Delaware on January 4, 2010, as a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or other similar business combination with one or more target businesses. On February 2, 2021, the Company consummated its initial public offering (the “IPO”), following which its shares began trading on the Nasdaq National Market (“Nasdaq”). On August 4, 2021, GCAC entered into a Business Combination Agreement (as amended, the “Merger Agreement”) with Cepton Technologies, Inc. (“Legacy Cepton”) and GCAC Merger Sub Inc., a wholly owned subsidiary of GCAC (“Merger Sub”). On February 10, 2022 (the “Closing Date”), the transactions contemplated by the Merger Agreement (the “Business Combination”) were consummated. In connection with the closing of the Business Combination, GCAC changed its name to Cepton, Inc. and its shares and public warrants began trading on the Nasdaq under the symbols “CPTN” and “CPTNW”, respectively. As a result of the Business Combination, Cepton, Inc. became the owner, directly or indirectly, of all of the equity interests of Legacy Cepton and its subsidiaries. The Company provides state-of-the-art, intelligent, lidar-based solutions for a range of markets such as automotive, smart cities, smart spaces, and smart industrial applications. The Company’s patented Micro Motion Technology (“MMT®”)-based lidar technology enables reliable, scalable, and cost-effective solutions that deliver long range, high resolution 3D perception for smart applications. The Company is headquartered in San Jose, California, USA, with a presence in Germany, Canada, Japan, China, and India.
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The condensed consolidated financial statements include the accounts of our wholly owned subsidiaries in Canada, Germany, and the United Kingdom. All intercompany balances and transactions have been eliminated in consolidation. The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. As of March 31, 2022, the Company had cash and cash equivalents of $24.6 million, short-term investment of $20.2 million, and an accumulated deficit of $54.2 million. During the three months ended March 31, 2022, the Company incurred an operating loss of $15.6 million and had negative cash flows from operating activities of $19.5 million. Although much of the negative cash flow resulted from an increase in expenses for research and development projects and expenses for preparing to become a publicly traded company, the Company expects to continue to invest in research and development and generate operating losses in the future. The Company is subject to risks and uncertainties frequently encountered by early-stage companies including, but not limited to, the uncertainty of successfully developing its products, securing certain contracts, building its customer base, successfully executing its business and marketing strategy and hiring appropriate personnel. To date, the Company has been funded primarily by equity financings, convertible promissory notes and other borrowings. Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, or secure additional funding may require the Company to modify, delay, or abandon some of its planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on the Company’s business, operating results, financial condition, and ability to achieve its intended business objectives.
Concentration of Risk	Concentration of Risk Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. The Company maintains a substantial portion of its cash and cash equivalents and short-term investments in money market funds, commercial paper, corporate debt securities, and asset backed securities. Management believes that the financial institutions that hold its cash, cash equivalents, and short-term investments are financially sound and, accordingly, represent minimal credit risk. Deposits held with banks may exceed the amount of federal insurance limits provided on such deposits. As of March 31, 2022 and December 31, 2021, three customers as of each period accounted for more than 10% of accounts receivable. Customers with revenue equal to or greater than 10% of total revenue for the periods indicated were as follows: Three Months Ended 2022 2021 Customer A 30 % 30 % Customer B 20 % 13 % Customer C — % 13 % Customer D — % 21 % Customer E — % 12 % Customer F 27 % — %
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include, but are not limited to, estimating the stand-alone selling prices of performance obligations for revenue recognition, allowances for doubtful accounts, inventory valuation and reserves, valuation allowance for deferred tax assets, share-based compensation including the fair value of the Company's common stock, useful lives of property and equipment, income tax uncertainties, the valuation of certain derivative liabilities, and other loss contingencies. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates, and such differences could be material to the Company's condensed consolidated financial condition and results of operations.
Product Warranties	Product Warranties The Company typically provides a one-year warranty on its products. Estimated future warranty costs are accrued and charged to cost of goods sold in the period that the related revenue is recognized. These estimates are derived from historical data and trends of product reliability and costs of repairing and replacing defective products. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Through March 31, 2022, there were immaterial changes to the accrued warranty liability which was recorded in accrued expenses and other current liabilities on the consolidated balance sheet.
