Nature of Business and Liquidity	Sep. 30, 2023
Nature of Business and Liquidity [Abstract]
Nature of Business and Liquidity	Note 1 – Nature of Business and Liquidity Organization Crown Electrokinetics Corp. (the “Company”) was incorporated in the State of Delaware on April 20, 2015. Effective October 6, 2017, the Company’s name was changed to Crown Electrokinetics Corp. from 3D Nanocolor Corp. (“3D Nanocolor”). The Company is commercializing technology for smart or dynamic glass. The Company’s electrokinetic glass technology is an advancement on microfluidic technology that was originally developed by HP Inc. On December 20, 2022, the Company incorporated Crown Fiber Optics Corp., a Delaware based entity, to own and operate its acquired business from the acquisition of Amerigen 7, LLC (“Amerigen 7”) in January 2023. Crown Fiber Optics Corp. is accounted for as a wholly-owned subsidiary of Crown Electrokinetics, Corp. Initial Public Offering On January 26, 2021, the Company completed its public offering, and its common stock began trading on the Nasdaq Capital Market (“Nasdaq”) under the symbol CRKN. Reverse Stock Split On August 11, 2023, the Company’s board of directors authorized a reverse stock split (‘Reverse Stock Split”) at an exchange ratio of one-for-60 basis. The Reverse Stock Split was effective on August 15, 2023, such that every 60 shares of common stock have been automatically converted into one share of common stock. The Company did not issue fractional certificates for post-reverse split shares in connection with the Reverse Stock Split. Rather, all shares of common stock that were held by a stockholder were aggregated and each stockholder was entitled to receive the number of whole shares resulting from the combination of the shares so aggregated. Any fractions resulting from the Reverse Stock Split computation were rounded up to the next whole share. The number of authorized shares and the par value of the common stock was not adjusted as a result of the Reverse Stock Split. In connection with the Reverse Stock Split, the conversion ratio for the Company’s outstanding convertible preferred stock was proportionately adjusted such that the common stock issuable upon conversion of such preferred stock was decreased in proportion to the Reverse Stock Split. All references to common stock and options to purchase common stock share data, per share data and related information contained in the condensed consolidated financial statements have been adjusted to reflect the effect of the Reverse Stock Split. Liquidity and Going Concern The Company has incurred substantial operating losses since its inception and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. As reflected in the condensed consolidated financial statements, the Company had an accumulated deficit of approximately $107.7 million and cash of approximately $2.1 million as of September 30, 2023, a net loss of approximately $19.7 million, and approximately $11.8 million of net cash used in operating activities for the nine months ended September 30, 2023. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. The Company has obtained additional capital through the sale of debt or equity financings or other arrangements to fund operations including through its existing at-the-market offering, $10.0 million Standing Letter of Credit (“SLOC”), $100.0 million line of credit, and $50.0 million equity line of credit; however, there can be no assurance that the Company will be able to raise needed capital under acceptable terms, if at all. The sale of additional equity may dilute existing stockholders and newly issued shares may contain senior rights and preferences compared to currently outstanding shares of common stock. Issued debt securities may contain covenants and limit the Company’s ability to pay dividends or make other distributions to stockholders. If the Company is unable to obtain such additional financing, future operations would need to be scaled back or discontinued. Due to the uncertainty in the Company’s ability to raise capital, management believes that there is substantial doubt in the Company’s ability to continue as a going concern for twelve months from the issuance of these condensed consolidated financial statements.

The condensed consolidated balance sheet as of September 30, 2023, the condensed consolidated statements of operations, stockholders’ equity for the three and nine months ended September 30, 2023 and 2022 and the condensed consolidated statements of cash flows for the nine months ended September 30, 2023 and 2022 are unaudited. These unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s consolidated financial position, results of operations and cash flows for the interim period presented. The financial data and the other financial information contained in these notes to the condensed consolidated financial statements related to the three and nine month periods are also unaudited. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future annual or interim period. The condensed consolidated balance sheet as of December 31, 2022 included herein was derived from the audited financial statements as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 31, 2023. Use of Estimates The preparation of condensed financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenue and expenses during the reporting periods. Accounting estimates and assumptions are inherently uncertain. Management bases its estimates and assumptions on current facts, historical experience and various other factors believed to be reasonable under the circumstances. Actual results could differ materially and adversely from these estimates. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but not limited to, valuation of its business combination, estimated fair value of convertible notes, estimated fair value of warrant lability, Series F/F-1/F-2 preferred stock, stock option awards for stock-based compensation and operating lease right-of-use assets and liabilities. Risks and Uncertainties The Company is currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due to the ongoing military conflict between Russia and Ukraine. The Company’s financial condition and results of operations may be materially adversely affected by any negative impact on the global economy and capital markets resulting from the conflict in Ukraine or any other geopolitical tensions. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Summary of Significant Accounting Policies Reference is made to Note 3 Basis of Presentation and Significant Accounting Policies Revenue Recognition The Company recognizes revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process: ● Step 1: Identify the contract with the customer ● Step 2: Identify the performance obligations in the contract ● Step 3: Determine the transaction price ● Step 4: Allocate the transaction price to the performance obligations in the contract ● Step 5: Recognize revenue when the company satisfies a performance obligation The Company has elected the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component when the time between the goods or service being transferred to the customer and the customer pays is one year or less, The Company generates revenue from providing fiber splicing services as required based on short-term work orders assigned by customers. The Company is required to complete the description of work described in the work order and test the service provided prior to any recognition of revenue and invoicing. The short-term work orders are generally completed within two weeks. The Company is required to adhere to the rules and regulations that are outlined in the Agreement between the Company and the Customer. Cost of revenue is based on individual work orders and detailed description of work to be performed. All of the revenue is recognized immediately upon completion of each work order. A 5% retainage will be withheld by the Customer upon payment of invoices and will be paid to the Company within one year after termination of the contract. The retainage can be utilized by Customer for any claims that may arise after work is completed up through one year after completion. Revenue recognized during the nine months ended September 30, 2023 was generated by the Company’s wholly-owned subsidiary, Crown Fiber Optics Corporation, and was immaterial. No revenue was recognized by the Company during the nine months ended September 30, 2022. Financial Instruments – Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments. The amendments in ASU No. 2016-13 introduce an approach based on expected losses to estimated credit losses on certain types of financial instruments, modify the impairment model for available-for-sale debt securities and provide for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new standard requires financial assets measured at amortized cost be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The standard is effective for the Company for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, using a modified retrospective approach. The Company adopted ASU No. 2016-13 and related updates as of January 1, 2023. The adoption of this guidance had no material impact on the Company’s condensed consolidated financial statements Segment and Reporting Unit Information Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is determined to be the CODM. The Company has two operating segments and two reportable segments as of September 30, 2023, which includes film group and fiber optics group. Revenue recognized during the nine months ended September 30, 2023 relates to the fiber optics group. Business Combinations The Company accounts for business combinations using the acquisition method of accounting by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, and any non-controlling interest in the acquired business, measured at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the aforementioned amounts. Accounting for business combinations requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for intangible assets. Although the Company believes the assumptions and estimates made have been reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired companies and are inherently uncertain. Critical estimates in valuing certain intangible assets we have acquired include future expected cash flows from customer contracts. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates, or actual results. The initial purchase price may be adjusted as needed per the terms of the arrangement agreement. The allocation of purchase price, including any fair value of the assets acquired and liabilities assumed as of the acquisition date has not been completed. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. Deferred Debt Issuance Costs The Company accounts for debt issuance costs related to its line of credit and equity line of credit as a deferred asset on the condensed consolidated balance sheets, which is amortized over the life of the line of credit and equity line of credit. Since the Company has elected the fair value option for its convertible notes (see Note 9), upon a draw down, a portion of the deferred asset balance will be amortized and recognized as other income (expense) on the condensed consolidated statements of operations. On the issuance date of the Company’s line of credit, the cost related to issuance of the Series E preferred shares and the warrant to purchase Series E preferred shares was recorded as a deferred asset. On the issuance date of the Company’s equity line of credit, the cost related to issuance of common stock was recorded as a deferred asset. Goodwill The Company performs a goodwill impairment analysis on October 1 st Notes Payable at Fair Value The Company has elected the fair value option for the recognition of its convertible notes and notes payable, with changes in fair value recognized in the statements of operations. As a result of applying the fair value option, direct costs and fees related to the convertible notes and notes payable are recognized in other income (expense) in the condensed consolidated statements of operations. The Company includes the interest expense as a component of the notes fair value. Warrants The Company accounts for certain common stock warrants outstanding as a liability at fair value and adjusts the fair value of the instruments at each reporting period. The liability is subject to remeasurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations. The fair value of the warrants issued by the Company was estimated using the Black-Scholes model. SLOC The Company accounts for its warrants related to the SLOC as stockholders’ equity, and therefore, the warrants are not revalued after issuance. The Company uses the Black-Scholes model to value the warrants at issuance. As of September 30, 2023, since no loan amounts were drawn down, the SLOC warrant is recorded as a deferred asset on the condensed consolidated balance sheets at fair value and will be amortized over the life of the SLOC. Upon a draw down, the remaining balance of the deferred asset would be reclassified to debt discount and amortized under the effective interest method over the one-year term of the loan. Purchase Order Warrants The Company accounts for its warrants issued in connection with purchase orders in accordance with ASC 606 . Net Loss per Share Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share attributable to common stockholders is computed using the sum of the weighted-average number of shares of common stock outstanding during the period and the effect of dilutive securities. As the Company was in a net loss position for the three and nine months ended September 30, 2023 and 2022, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders because the effects of potentially dilutive securities are antidilutive. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at September 30, 2023 and 2022 are as follows: September 30, 2023 2022 Series A preferred stock 3,146 3,146 Series B preferred stock 33,883 33,883 Series C preferred stock 9,346 9,346 Series D preferred stock - 35,278 Series F preferred stock 501,579 - Series F-1 preferred stock 72,631 - Series F-2 preferred stock 124,946 - Warrants to purchase common stock (excluding penny warrants) 1,760,095 98,402 Warrants to purchase Series E preferred stock 750,000 - Options to purchase common stock 157,779 164,996 Unvested restricted stock units 7,139 14,796 Commitment shares 200,205 - Total 3,620,749 359,847

Notes Payable [Abstract]
Notes Payable	Note 9 – Notes Payable Convertible Notes 2022 Notes In October 2022, the Company issued convertible notes (the “2022 Notes”) with a principal balance of approximately $5.4 million and warrants to purchase 362,657 shares of the Company’s common stock for net proceeds of $3.5 million. The 2022 Notes is non-interest bearing and secured by the Company’s assets. The maturity date is the earlier of (i) twelve months from the date of issuance or (ii) the closing of a change of control transaction. The 2022 Notes are convertible into shares of the Company’s common stock at a conversion price of $29.70 per share. The warrants have an exercise price of $19.32 per share and expire five years from the issuance date. In February 2023, the Company entered into waiver agreements with holders of the 2022 Notes which extended the maturity date of the 2022 Notes from October 19, 2023 to April 18, 2024. As consideration for this agreement, the Company issued 96,890 warrants to purchase shares of the Company’s common stock (See Note 10). In March 2023, the Company entered into the waiver agreements with holders of the 2022 Notes to eliminate the minimum pricing covenant as it relates to Company’s at-the-market facility. As consideration for this agreement, the Company provided the holders with two options to choose from (i) to take an additional five percent original issue discount (“OID”) on their 2022 Note principal or (ii) to be issued shares of common stock with a value equal to the five percent OID, and to issue total shares of 31,724 as converted using the Nasdaq minimum price of $9.42. During the nine months ended September 30, 2023, six of the note holders elected option (i), and the Company increased the respective principal balance of the notes by approximately $0.2 million. The remaining noteholders elected option (ii), and as of September 30, 2023, no shares of common stock have been issued. The Company recorded expense of $0.3 million associated with the commitment to issue shares of the Company’s common stock. In May 2023, the Company entered into an inducement agreements with the investors to reduce the conversion price of the 2022 Notes in an aggregate principal amount equal to $1.5 million, convertible into 161,603 shares of the Company’s common stock at $9.28 per share. The remaining investors agreed to reduce the conversion price of the 2022 Notes in an aggregate principal amount equal to $1.4 million, convertible into 127,393 shares of the Company’s common stock at $10.93 per share. The Company elected to account for the 2022 Notes under the fair value option. For the inducement agreements that were entered into as described above, the Company accounted for the change in the terms through the fair value adjustment of $2.7 million, which is included in the change in fair value of notes on the condensed consolidated statements of operations, upon the settlement of $0.2 million principal balance of the 2022 Notes as part of the exchange agreements, and $1.0 million principal balance of the 2022 Notes in June 2023 based on the issuance of 248,981 shares of the Company’s common stock. Senior Secured Notes In January 2023, the Company issued senior secured notes (“Senior Secured Notes”) with a principal balance of approximately $1.2 million and warrants to purchase 41,667 shares of the Company’s common stock for net proceeds of $1.0 million. The Senior Secured Notes do not bear interest, and mature three months from the date of issuance. Pursuant to these terms, the Senior Secured Notes were subsequently extended to May 3, 2023, incurring an additional 10% on principal. The warrants are exercisable for five years at an exercise price of $19.32 per share. In May 2023, the Company entered into several amendments to extend the Senior Secured Notes maturity date with the investors. In exchange, the Company issued a total of 203,500 shares of common stock to the investors. The Company concluded that a troubled debt restructuring did not occur, but an extinguishment of the outstanding senior secured notes occurred. Subsequent to the extinguishment, the Company concluded to account for the Senior Secured Notes using the fair value option. The Company recorded an extinguishment loss of $2.2 million. On June 4, 2023, $0.2 million of the outstanding Senior Secured Notes was settled. The Company accounted for the settlement as an extinguishment that resulted in a $0.1 million gain and resulted in $0.1 million being recorded as Series F convertible preferred stock and $0.1 million being recorded as part of the warrant liability. On June 30, 2023, the Company and the remaining investors agreed to extend the maturity date of the 2023 Notes until July 31, 2023, in exchange for 41,667 shares of common stock. The Company recorded a change in fair value adjustment of $0.3 million based on the fair value of the 41,667 shares of common stock. On July 10, 2023, the Company and the remaining investors entered into a forbearance agreement, which was subsequently amended on July 14, 2023. The forbearance agreement provides that the investor shall forbear the exercise of its rights and remedies due to certain events of defaults under the Senior Secured Notes, including payment, until December 31, 2023, in exchange for a non-refundable and indefeasible payment of $0.1 million in the form of a promissory note due December 31, 2023 (the “December 2023 Note).

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 10 - Fair Value Measurements The following table classifies the Company’s liabilities measured at fair value on a recurring basis into the fair value hierarchy as of September 30, 2023 and December 31, 2022: Fair value measured at September 30, 2023 Total Quoted Significant Significant Liabilities: Warrant liability $ 34 $ - $ - $ 34 Fair value measured at December 31, 2022 Total Quoted Significant Significant Liabilities: Convertible notes $ 1,654 $ - $ - $ 1,654 Warrant liability $ 972 $ - $ - $ 972 For the nine months ended September 30, 2023 there was a decrease of approximately $2.6 million in Level 3 liabilities measured at fair value. 2022 Convertible Notes at Fair Value The fair value of the 2022 Notes on the issuance dates, and as of September 30, 2023 were estimated using a Monte Carlo simulation to capture the path dependencies intrinsic to their terms. The significant unobservable inputs used in the fair value measurement of the Company’s convertible notes are the common stock price, volatility, and risk-free interest rates. The Company elected the fair value option when recording its 2022 Notes and the 2022 Notes were classified as liabilities and measured at fair value on the issuance date, with changes in fair value recognized as other income (expense) on the statements of operations and disclosed in the condensed consolidated financial statements. During the nine months ended September 30, 2023, seven noteholders converted a portion of their 2022 Notes into 248,981 shares of the Company’s commons stock (See Note 9). The fair value of the converted notes totaled $2.2 million. In February 2023, the Company entered into waiver agreements with holders of the 2022 Notes (See Note 9). In connection with the waiver agreement, the 2022 Notes were revalued as of the amendment date. In March 2023, the Company entered into the second waiver agreements with holders of the 2022 Notes (See Note 9). A number of holders elected to increase the principal balance of their notes. The Company revalued the respective notes on the date prior to the amendment date and again on the amendment date. The change in fair value related to the amendment of these 2022 Notes was approximately $0.4 million. In June 2023, the Company entered into an exchange agreement and $0.2 million fair value of the 2022 Notes was exchanged for 206 shares of Series F Preferred stock. As of September 30, 2023, there was no outstanding balance related to the 2022 Notes. Line of Credit In February 2023, the Company drew down $2.0 million from the line of credit and issued the 2023 Notes of $2.0 million.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial period of 180 calendar days, or until April 16, 2024, to regain compliance with the Bid Price Rule. The letter states that the Nasdaq staff will provide written notification that the Company has achieved compliance with Bid Price Rule if at any time before April 16, 2024, the bid price of the Company’s common stock closes at $1.00 per share or more for a minimum of ten (10) consecutive business days.

If the Company does not regain compliance with the Bid Price Rule by April 16, 2024, the Company may be eligible for an additional 180 calendar day compliance period. To qualify, the Company will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Bid Price Rule, and will need to provide written notice of its intention to cure the deficiency during the second compliance period, for example, by effecting a reverse stock split, if necessary. However, if it appears to the Nasdaq staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq will notify the Company that its securities will be subject to delisting. In the event of such a notification, the Company may appeal the Nasdaq staff’s determination to delist its securities. There can be no assurance that the Company will be eligible for the additional 180 calendar day compliance period, if applicable, or that the Nasdaq staff would grant the Company’s request for continued listing subsequent to any delisting notification.

The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023 or for any other future annual or interim period. The condensed consolidated balance sheet as of December 31, 2022 included herein was derived from the audited financial statements as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 31, 2023.
Use of Estimates	Use of Estimates The preparation of condensed financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenue and expenses during the reporting periods. Accounting estimates and assumptions are inherently uncertain. Management bases its estimates and assumptions on current facts, historical experience and various other factors believed to be reasonable under the circumstances. Actual results could differ materially and adversely from these estimates. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but not limited to, valuation of its business combination, estimated fair value of convertible notes, estimated fair value of warrant lability, Series F/F-1/F-2 preferred stock, stock option awards for stock-based compensation and operating lease right-of-use assets and liabilities.
Risks and Uncertainties	Risks and Uncertainties The Company is currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due to the ongoing military conflict between Russia and Ukraine. The Company’s financial condition and results of operations may be materially adversely affected by any negative impact on the global economy and capital markets resulting from the conflict in Ukraine or any other geopolitical tensions. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Reference is made to Note 3 Basis of Presentation and Significant Accounting Policies
Revenue Recognition	Revenue Recognition The Company recognizes revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process: ● Step 1: Identify the contract with the customer ● Step 2: Identify the performance obligations in the contract ● Step 3: Determine the transaction price ● Step 4: Allocate the transaction price to the performance obligations in the contract ● Step 5: Recognize revenue when the company satisfies a performance obligation The Company has elected the practical expedient to not adjust the promised amount of consideration for the effects of a significant financing component when the time between the goods or service being transferred to the customer and the customer pays is one year or less, The Company generates revenue from providing fiber splicing services as required based on short-term work orders assigned by customers. The Company is required to complete the description of work described in the work order and test the service provided prior to any recognition of revenue and invoicing. The short-term work orders are generally completed within two weeks. The Company is required to adhere to the rules and regulations that are outlined in the Agreement between the Company and the Customer. Cost of revenue is based on individual work orders and detailed description of work to be performed. All of the revenue is recognized immediately upon completion of each work order. A 5% retainage will be withheld by the Customer upon payment of invoices and will be paid to the Company within one year after termination of the contract. The retainage can be utilized by Customer for any claims that may arise after work is completed up through one year after completion. Revenue recognized during the nine months ended September 30, 2023 was generated by the Company’s wholly-owned subsidiary, Crown Fiber Optics Corporation, and was immaterial. No revenue was recognized by the Company during the nine months ended September 30, 2022.
Financial Instruments – Credit Losses	Financial Instruments – Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments. The amendments in ASU No. 2016-13 introduce an approach based on expected losses to estimated credit losses on certain types of financial instruments, modify the impairment model for available-for-sale debt securities and provide for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new standard requires financial assets measured at amortized cost be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The standard is effective for the Company for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, using a modified retrospective approach. The Company adopted ASU No. 2016-13 and related updates as of January 1, 2023. The adoption of this guidance had no material impact on the Company’s condensed consolidated financial statements
Segment and Reporting Unit Information	Segment and Reporting Unit Information Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is determined to be the CODM. The Company has two operating segments and two reportable segments as of September 30, 2023, which includes film group and fiber optics group. Revenue recognized during the nine months ended September 30, 2023 relates to the fiber optics group.
Business Combinations	Business Combinations The Company accounts for business combinations using the acquisition method of accounting by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, and any non-controlling interest in the acquired business, measured at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the aforementioned amounts. Accounting for business combinations requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for intangible assets. Although the Company believes the assumptions and estimates made have been reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired companies and are inherently uncertain. Critical estimates in valuing certain intangible assets we have acquired include future expected cash flows from customer contracts. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates, or actual results. The initial purchase price may be adjusted as needed per the terms of the arrangement agreement. The allocation of purchase price, including any fair value of the assets acquired and liabilities assumed as of the acquisition date has not been completed. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
Deferred Debt Issuance Costs	Deferred Debt Issuance Costs The Company accounts for debt issuance costs related to its line of credit and equity line of credit as a deferred asset on the condensed consolidated balance sheets, which is amortized over the life of the line of credit and equity line of credit. Since the Company has elected the fair value option for its convertible notes (see Note 9), upon a draw down, a portion of the deferred asset balance will be amortized and recognized as other income (expense) on the condensed consolidated statements of operations. On the issuance date of the Company’s line of credit, the cost related to issuance of the Series E preferred shares and the warrant to purchase Series E preferred shares was recorded as a deferred asset. On the issuance date of the Company’s equity line of credit, the cost related to issuance of common stock was recorded as a deferred asset.
Goodwill	Goodwill The Company performs a goodwill impairment analysis on October 1 st
Notes Payable at Fair Value	Notes Payable at Fair Value The Company has elected the fair value option for the recognition of its convertible notes and notes payable, with changes in fair value recognized in the statements of operations. As a result of applying the fair value option, direct costs and fees related to the convertible notes and notes payable are recognized in other income (expense) in the condensed consolidated statements of operations. The Company includes the interest expense as a component of the notes fair value.
Warrant	Warrants The Company accounts for certain common stock warrants outstanding as a liability at fair value and adjusts the fair value of the instruments at each reporting period. The liability is subject to remeasurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations. The fair value of the warrants issued by the Company was estimated using the Black-Scholes model. SLOC The Company accounts for its warrants related to the SLOC as stockholders’ equity, and therefore, the warrants are not revalued after issuance. The Company uses the Black-Scholes model to value the warrants at issuance. As of September 30, 2023, since no loan amounts were drawn down, the SLOC warrant is recorded as a deferred asset on the condensed consolidated balance sheets at fair value and will be amortized over the life of the SLOC. Upon a draw down, the remaining balance of the deferred asset would be reclassified to debt discount and amortized under the effective interest method over the one-year term of the loan. Purchase Order Warrants The Company accounts for its warrants issued in connection with purchase orders in accordance with ASC 606 .
Net Loss per Share Attributable to Common Stockholders	Net Loss per Share Attributable to Common Stockholders Basic net loss per share attributable to common stockholders is computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share attributable to common stockholders is computed using the sum of the weighted-average number of shares of common stock outstanding during the period and the effect of dilutive securities. As the Company was in a net loss position for the three and nine months ended September 30, 2023 and 2022, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders because the effects of potentially dilutive securities are antidilutive. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at September 30, 2023 and 2022 are as follows: September 30, 2023 2022 Series A preferred stock 3,146 3,146 Series B preferred stock 33,883 33,883 Series C preferred stock 9,346 9,346 Series D preferred stock - 35,278 Series F preferred stock 501,579 - Series F-1 preferred stock 72,631 - Series F-2 preferred stock 124,946 - Warrants to purchase common stock (excluding penny warrants) 1,760,095 98,402 Warrants to purchase Series E preferred stock 750,000 - Options to purchase common stock 157,779 164,996 Unvested restricted stock units 7,139 14,796 Commitment shares 200,205 - Total 3,620,749 359,847
