Nature of Operations	NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND LIQUIDITY Roth CH Acquisition IV Co. (the “Company”) was incorporated in Delaware on February 13, 2019. The Company is a blank check company formed for the purpose of entering into a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of March 31, 2023, the Company had not commenced any operations. All the Company’s activities through March 31, 2023 related to its formation and the initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non -operating The registration statement for the Company’s Initial Public Offering was declared effective on August 5, 2021. On August 10, 2021, the Company consummated the Initial Public Offering of 11,500,000 units (the “Units” and, with respect to the shares of common stock included in the Units sold, the “Public Shares”), which included the full exercise by the underwriters of their over -allotment Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 461,500 units (the “Private Units”) at a price of $10.00 per Private Unit in a private placement to certain of the Company’s initial stockholders, generating gross proceeds of $4,615,000, which is described in Note 4. Transaction costs amounted to $1,646,673, consisting of $1,150,000 of underwriting fees, and $496,673 of other offering costs. Following the closing of the Initial Public Offering on August 10, 2021, an amount of $116,725,000 ($10.15 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Units was placed in a trust account (the “Trust Account”), located in the United States and held in cash items or invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open -ended -7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete a Business Combination having an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding taxes payable on income earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. The Company will only complete a Business Combination if the post -transaction The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.15 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC containing substantially the same information as would be included in a proxy statement prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the holders of the Company’s shares prior to the Initial Public Offering (the “Initial Stockholders”) have agreed (a) to vote their Founder Shares (as defined in Note 5), Private Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination, to the extent permitted by law, and (b) not to redeem any shares in connection with a stockholder vote to approve a Business Combination or sell any shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares, irrespective of how or whether they vote on the proposed transaction or do not vote at all. The Initial Stockholders have agreed (a) to waive their redemption rights with respect to their Founder Shares, Private Shares and Public Shares held by them in connection with the completion of a Business Combination and (b) not to propose an amendment to the Amended and Restated Certificate of Incorporation that would affect a public stockholders’ ability to convert or sell their shares to the Company in connection with a Business Combination or affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. The Company will have until July 10, 2023 to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purposes of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter redeem 100% of the Public Shares for cash for a redemption price per share as described below (which redemption will completely extinguish such holders’ rights as stockholders, including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to approval of the Company’s then stockholders and subject to the requirements of the DGCL, including the adoption of a resolution by the Board of Directors pursuant to Section 275(a) of the DGCL finding the dissolution of the Company advisable and the provision of such notices as are required by said Section 275(a) of the DGCL, dissolve and liquidate the balance of the Company’s net assets to its remaining stockholders, as part of the Company’s plan of dissolution and liquidation, subject (in the case of (ii) and (iii) above) to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law. In such event, the per share redemption price shall be equal to a pro rata share of the Trust Account plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company for its working capital requirements or necessary to pay its taxes divided by the total number of Public Shares then outstanding. The Initial Stockholders have agreed to waive their liquidation rights with respect to the Founder Shares and Private Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Stockholders acquire Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit. In order to protect the amounts held in the Trust Account, certain of the Initial Stockholders have agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.15 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a valid and enforceable agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Initial Stockholders will not be responsible to the extent of any liability for such third -party On January 9, 2023, the Company received a letter from The Nasdaq Stock Market LLC (“Nasdaq”), which stated that the Company no longer complied with Nasdaq’s continued listing rules due to the Company not having held an annual meeting of shareholders within 12 months of the Company’s fiscal year end, as required pursuant to Nasdaq Listing Rule 5620(a). In accordance with Nasdaq Listing Rule 5810(c)(2)(G), the Company had 45 calendar days to submit a plan to regain compliance and, if Nasdaq accepted the plan, Nasdaq would grant the Company an exception of up to 180 calendar days from the fiscal year end, or until June 29, 2023, to regain compliance. The Company held its Annual Meeting of Stockholders on February 13, 2023. On February 10, 2023, March 10, 2023, April 10, 2023, and May 10, 2023 Tigo Energy paid certain Initial Stockholders an aggregate amount of $326,362 (or $0.05 per share), according to the terms of the Non -Redemption -month Merger Agreement On December 5, 2022, the Company, entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among the Company, Roth IV Merger Sub Inc., a Delaware corporation and a wholly -owned Subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into Tigo Energy, with Tigo Energy surviving as a wholly -owned Consideration Subject to the terms and conditions set forth in the Merger Agreement, in consideration of the Merger, the base purchase price of $600,000,000 will be payable through converting each outstanding share of Tigo Energy’s common stock (after giving effect to the consummation of Tigo Energy’s warrant exercise and Tigo Energy’s preferred conversion) into the right to receive 60,000,000 The base purchase price is subject to a dollar -for-dollar -money -money -money Trust Extension On December 20, 2022, the Company held a special meeting of stockholders, at which the Company’s stockholders approved an amendment (the “Extension Amendment”) to the Company’s amended and restated certificate of incorporation, to extend the date by which the Company has to consummate a business combination up to five (5) times, each such extension for an additional one (1) month period, from February 10, 2023 to July 10, 2023. In connection with the Extension Amendment, stockholders holding 9,121,751 Liquidity and Going Concern As of March 31, 2023, the Company had $123,759 in its operating bank account and adjusted working capital deficit of $886,992 which excludes franchise and income taxes payable as such amounts can be paid from the interest earned in the Trust Account. Until the consummation of a Business Combination, the Company will be using the funds not held in the Trust Account for performing due diligence on prospective target businesses, paying for travel expenditures, and structuring, negotiating, and consummating the Business Combination. The Company has a significant working capital deficiency and has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans. The Company will need to raise additional capital through loans or additional investments from the Initial Stockholders and the Company’s officers and directors or their affiliates. The Initial Stockholders and the Company’s officers and directors or their affiliates may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. If the Company is unable to complete the Business Combination because it does not have sufficient funds available, the Company will be forced to cease operations and liquidate the Trust Account. In connection with the Company’s assessment of going concern considerations in accordance with the Financial Accounting Standards Board’s (“FASB’s”) Accounting Standards Update (“ASU”) 2014 -15 -Q Risks and Uncertainties Management continues to evaluate the impact of the COVID -19 -19 Inflation Reduction Act of 2022 On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax. Any redemption or other repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any “PIPE” or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and in the Company’s ability to complete a Business Combination.	NOTE 1.

Following the closing of the Initial Public Offering on August 10, 2021, an amount of $116,725,000 ($10.15 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Units was placed in a trust account (the “Trust Account”), located in the United States and held in cash items or invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open -ended -7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete a Business Combination having an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding taxes payable on income earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. The Company will only complete a Business Combination if the post -transaction The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially $10.15 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Company will proceed with a Business Combination If the Company has net tangible assets of at least $5,000,001 either immediately prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC containing substantially the same information as would be included in a proxy statement prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the holders of the Company’s shares prior to the Initial Public Offering (the “Initial Stockholders”) have agreed (a) to vote their Founder Shares (as defined in Note 6), Private Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination, to the extent permitted by law, and (b) not to redeem any shares in connection with a stockholder vote to approve a Business Combination or sell any shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares, irrespective of how or whether they vote on the proposed transaction. The Initial Stockholders have agreed (a) to waive their redemption rights with respect to their Founder Shares, Private Shares and Public Shares held by them in connection with the completion of a Business Combination and (b) not to propose an amendment to the Amended and Restated Certificate of Incorporation that would affect a public stockholders’ ability to convert or sell their shares to the Company in connection with a Business Combination or affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. The Company will have until July 10, 2023 to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company shall (i) cease all operations except for the purposes of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter redeem 100% of the Public Shares for cash for a redemption price per share as described below (which redemption will completely extinguish such holders’ rights as stockholders, including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to approval of the Company’s then stockholders and subject to the requirements of the DGCL, including the adoption of a resolution by the Board of Directors pursuant to Section 275(a) of the DGCL finding the dissolution of the Company advisable and the provision of such notices as are required by said Section 275(a) of the DGCL, dissolve and liquidate the balance of the Company’s net assets to its remaining stockholders, as part of the Company’s plan of dissolution and liquidation, subject (in the case of (ii) and (iii) above) to the Company’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law. In such event, the per share redemption price shall be equal to a pro rata share of the Trust Account plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company for its working capital requirements or necessary to pay its taxes divided by the total number of Public Shares then outstanding. The Initial Stockholders have agreed to waive their liquidation rights with respect to the Founder Shares and Private Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Stockholders acquire Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit. In order to protect the amounts held in the Trust Account, certain of the Initial Stockholders have agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.15 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a valid and enforceable agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Initial Stockholders will not be responsible to the extent of any liability for such third -party Merger Agreement On December 5, 2022, the Company, entered into an Agreement and Plan of Merger (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among the Company, Roth IV Merger Sub Inc., a Delaware corporation and a wholly -owned Subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into Tigo Energy, with Tigo Energy surviving as a wholly -owned Consideration Subject to the terms and conditions set forth in the Merger Agreement, in consideration of the Merger, the base purchase price of $600,000,000 will be payable through converting each outstanding share of Tigo Energy’s common stock (after giving effect to the consummation of Tigo Energy’s warrant exercise and Tigo Energy’s preferred conversion) into the right to receive 60,000,000 The base purchase price is subject to a dollar -for-dollar -money -money -money Trust Extension On December 20, 2022, the Company held a special meeting of stockholders, at which the Company’s stockholders approved an amendment (the “Extension Amendment”) to the Company’s amended and restated certificate of incorporation, to extend the date by which the Company has to consummate a business combination up to five (5) times, each such extension for an additional one (1) month period, from February 10, 2023 to July 10, 2023. In connection with the Extension Amendment, stockholders holding 9,121,751 Liquidity and Going Concern As of December 31, 2022, the Company had $88,107 in its operating bank account and adjusted working capital deficit of $290,839 which excludes franchise and income taxes payable as such amounts can be paid from the interest earned in the Trust Account. Until the consummation of a Business Combination, the Company will be using the funds not held in the Trust Account for performing due diligence on prospective target businesses, paying for travel expenditures, and structuring, negotiating, and consummating the Business Combination. The Company has a significant working capital deficiency and has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans. The Company will need to raise additional capital through loans or additional investments from the Initial Stockholders and the Company’s officers and directors or their affiliates. The Initial Stockholders and the Company’s officers and directors or their affiliates may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. If the Company is unable to complete the Business Combination because it does not have sufficient funds available, the Company will be forced to cease operations and liquidate the Trust Account. In connection with the Company’s assessment of going concern considerations in accordance with the Financial Accounting Standards Board’s (“FASB’s”) Accounting Standards Update (“ASU”) 2014 -15 subsequent dissolution of the Company. Management has determined that the liquidity condition and the date for mandatory liquidation and subsequent dissolution raises substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after July 10, 2023. The Company intends to complete a Business Combination before the mandatory liquidation date. The Company is within 12 months of its mandatory liquidation date as of the time of filing this Annual Report on Form 10 -K Risks and Uncertainties Management continues to evaluate the impact of the COVID -19 -19 Inflation Reduction Act of 2022 On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of publicly traded foreign corporations occurring on or after January 1, 2023. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax. Any redemption or other repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any “PIPE” or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and in the Company’s ability to complete a Business Combination.

Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). In the opinion of management, the accompanying unaudited condensed consolidated interim financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the unaudited condensed consolidated interim financial statements) considered necessary to present fairly Tigo’s consolidated financial position as of March 31, 2023 and its consolidated results of operations, cash flows, and convertible preferred stock and changes in stockholders’ deficit for the three months ended March 31, 2023 and 2022. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023. The unaudited condensed consolidated interim financial statements, presented herein, do not contain all of the required disclosures under GAAP for annual consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2022 has been derived from the audited consolidated balance sheet as of that date. The accompanying unaudited condensed consolidated interim financial statements should be read in conjunction with the annual audited consolidated financial statements and related notes thereto for the year ended December 31, 2022. Basis of Consolidation The unaudited condensed consolidated interim financial statements include the accounts of Tigo and its wholly -owned -average Reclassification Certain prior period amounts in the unaudited condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. Liquidity and Going Concern The Company follows the provisions of FASB ASC Topic 205 -40 The Company has historically incurred recurring net losses and negative cash flows from operating activities and has an accumulated deficit of $55.3 million at March 31, 2023. Management believes that with the existing cash, cash equivalents, and marketable securities as of March 31, 2023, and an increasing customer base, as well as proper management of expenditures, Tigo has sufficient resources to sustain operations through May 2024. However, there is no certainty that management will be successful in these efforts and, if Tigo requires additional debt or equity financing, there is no assurance that it will be available at terms acceptable to Tigo, or at all. Cash and Cash Equivalents The Company’s cash and cash equivalents include short -term -liquid -liquid Marketable Securities The Company’s marketable securities consist of investments in U.S. agency securities and corporate bonds that are classified as available -for-sale Business Combinations The Company accounts for business combinations under ASC Topic 805, Business Combinations If the initial accounting for a business combination is incomplete by the end of a reporting period that falls within the measurement period, the Company reports provisional amounts in the unaudited condensed consolidated interim financial statements. During the measurement period, the provisional amounts recognized at the acquisition date will be adjusted to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and the Company records those adjustments in the unaudited condensed consolidated interim financial statements. Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the identifiable tangible and intangible assets acquired in addition to liabilities assumed arising from the business combination. Initially the Company measures goodwill based upon the value of the consideration paid plus or minus net assets assumed. The goodwill arising from the Company’s acquisition is attributable to the value of the potential expanded market opportunity with new customers. The goodwill balance as of March 31, 2023 relates to the Company’s purchase of fSight. Intangible assets have either an identifiable or indefinite useful life. Intangible assets are recorded at cost or when acquired as part of a business combination at estimated fair value. Intangible assets with identifiable useful lives are amortized on a straight -line Goodwill is not amortized but is subject to annual impairment testing unless circumstances dictate more frequent assessments. The Company will perform an annual impairment assessment for goodwill and more frequently whenever events or changes in circumstances indicate that the fair value of the asset may be less than the carrying amount. Fair Value of Financial Instruments The Company uses a three -level -based -specific defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with those financial instruments. The three -level • Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. • Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liabilities. • Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Revenue Recognition The Company follows ASC Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”) for revenue recognition. In accounting for contracts with customers: The Company determines revenue recognition through the following steps: • • • • • The Company’s primary source of revenue is the sale of its hardware products. The Company’s hardware products are fully functional at the time of shipment and do not require modification or customization for customers to use the products. The Company sells its products primarily to distributors that resell the Company’s products to end users. Distributors do not have general rights of return and generally order goods for immediate resale to end customers. The Company uses present right to payment and transfer of title as indicators to determine the transfer of control to the customer. The Company recognizes revenue at a point in time when its performance obligation has been satisfied and control of the product is transferred to the customer, which generally aligns with shipping terms. Contract shipping terms include ExWorks (“EXW”), FOB Shipping Point and FOB Destination incoterms. Under EXW (meaning the seller fulfills its obligation to deliver when it makes goods available at its premises, or another specified location, for the buyer to collect), the performance obligation is satisfied and control is transferred at the point when the customer is notified that their order is available for pickup. Under FOB Shipping Point, control is transferred to the customer at the time the good is transferred to the shipper and under FOB Destination, at the time the customer receives the goods. The Company deduct sales returns to arrive at revenue, net. Sales tax and other similar taxes are excluded from revenues. The Company has made the election to account for shipping and handling as activities to fulfill the promise to transfer the product and as such records amounts charged to customers for shipping and handling as revenue and the related costs are included in cost of revenues. The Company typically incurs incremental costs to acquire customer contracts in the form of sales commissions; however, because the expected benefit from these contracts is one year or less, the Company expenses these amounts as incurred. Product warranty costs are recorded as expense to cost of revenue based on customer history, historical information and current trends. Sales of the Company’s hardware products include the Company’s web -based Deferred revenue or contract liabilities consists of payments received from customers in advance of revenue recognition for the Company’s products and service. The current portion of deferred revenue represents the unearned revenue that will be earned within 12 months of the balance sheet date. Correspondingly, noncurrent deferred revenue represents the unearned revenue that will be earned after 12 months from the balance sheet date. The following table summarizes the changes in deferred revenue: Three Months Ended (in thousands) 2023 2022 Balance at the beginning of the period $ 1,122 $ 232 Deferral of revenue 12,198 2,285 Recognition of unearned revenue (11,712 ) (1,666 ) Balance at the end of the period $ 1,608 $ 851 As of March 31, 2023, the Company expects to recognize $1.6 million from remaining performance obligations over a weighted average term of 1.7 years. The Company recognized approximately $0.7 million and $0.2 million in revenue that was included in the beginning contract liabilities balance during the three months ended March 31, 2023 and 2022, respectively. Net Income (Loss) Per Common Share Basic net income (loss) per share of common stock is computed by dividing net income (loss) attributable to common stockholders by the weighted -average -average -stock -converted -class Under the two -class -class The following table sets forth the computation of basic and diluted net income (loss) per share to common stockholders: Three Months Ended (in thousands, except share and per share data) 2023 2022 Basic net income (loss) per common share calculation: Net income (loss) attributable to common stockholders $ 4,758 $ (6,487 ) Less: undistributed earnings to participating shareholders (4,176 ) — Net income (loss) attributable to common stockholders – basic 582 (6,487 ) Weighted-average shares of common stock outstanding – basic 27,779,209 20,624,803 Net income (loss) per share of common stock, basic $ 0.02 $ (0.31 ) Diluted net income (loss) per common share calculation: Net income (loss) attributable to common stockholders – diluted $ 582 $ (6,487 ) Weighted-average shares of common stock outstanding, basic 27,779,209 20,624,803 Stock options 13,532,987 — Warrants 5,852,334 — Weighted-average shares of common stock, diluted 47,164,530 20,624,803 Net income (loss) per share of common stock – diluted $ 0.01 $ (0.31 ) The following potentially dilutive securities have been excluded from the computation of diluted weighted -average -dilutive As of March 31, 2023 2022 Convertible preferred stock — 165,578,120 Convertible preferred stock warrants — 1,185,599 Common stock warrants 758,891 8,208,682 Convertible promissory note 23,376,468 — Stock options 1,367,000 17,604,360 25,502,359 192,576,761 Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016 -13 In December 2019, the FASB issued ASU No. 2019 -12 -12 -public -year In February 2016, the FASB issued ASU No. 2016 -02 -of-use -lease -term	3. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the ASC and Accounting Standards Updates (“ASU”) promulgated by the FASB. Basis of Consolidation The consolidated financial statements include the accounts of Tigo and its wholly -owned -average Reclassification Certain prior period amounts in the consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. Use of Estimates The preparation of the consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates due to risk and uncertainties, including uncertainty in the current economic environment due to the global impact of COVID -19 -lived -based Risks and Uncertainties The Company is subject to a number of risks inherent in a business without substantial operating history, including, but not limited to, new and evolving markets, advances and trends in the development of new technology and services and regulations thereon, unfavorable economic and market conditions, competition from other companies with longer operating histories and greater financial resources, the ability to obtain adequate funding, dependence on key employees and the ability to attract and retain qualified employees. Concentrations of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash, restricted cash, and accounts receivable. The Company maintains deposits in federally insured financial institutions, which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant credit risk beyond the normal credit risk associated with commercial banking relationships as the Company’s cash and restricted cash are deposited with major financial institutions in the U.S., Europe, the Middle East and Asia. At December 31, 2022 and 2021, the Company held insignificant cash in foreign bank accounts. To date, the Company has not experienced any losses on its deposits of cash. During the year ended December 31, 2022, there was one individual customer that exceeded 10% of the Company’s annual revenue, net. This customer accounted for 10.6% of revenue, net. Accounts receivable from this customer represented $2.1 million. During the year ended December 31, 2021, there was one individual customer that exceeded 10% of the Company’s annual revenue, net. This customer accounted for 14% of revenue, net. Accounts receivable from this customer represented $0.5 million. Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker (“CODM”), or decision- making group, in deciding how to allocate resources and in assessing performance. The CODM is the Company’s Chief Executive Officer. The Company views and manages its operations as a single operating segment. Foreign Operations Operations outside the U.S. include subsidiaries in Israel, Italy and China. Foreign operations are subject to risks inherent in operating under different legal systems and various political and economic environments. Among those risks are changes in existing tax laws, possible limitations on foreign investment and income repatriation, government price or foreign exchange controls, and restrictions on currency exchange. Net liabilities of foreign operations were $0.7 million and $0.2 million at December 31, 2022 and 2021, respectively. Revenue, net from foreign customers represented 73% and 61% of revenue, during the years ended December 31, 2022 and 2021, respectively. There were two foreign countries individually representing greater than 10% of revenue, net during the year ended December 31, 2022 and totaled 37% of revenue, net. There were two foreign countries individually representing greater than 10% of revenue, net during the year ended December 31, 2021 and totaled 27% of revenue, net. Accounts receivable due from foreign customers was 80% and 65% of total accounts receivable at December 31, 2022 and 2021, respectively. Fair Value of Financial Instruments The Company uses a three -level -based -specific -level Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liabilities. Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Management believes that the carrying amounts of the Company’s financial instruments, including cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate fair value due to the short -term Cash and Cash Equivalents The Company’s cash and cash equivalents include short -term -liquid -liquid Restricted Cash and Reconciliation to the Consolidated Statements of Cash Flows Restricted cash represents amounts held on deposit at a commercial bank used to secure the Company’s Senior Bonds (Note 9). The following table provides a reconciliation of the components of cash and cash equivalents and restricted cash reported in the Company’s consolidated balance sheets to the total of the amount presented in the consolidated statements of cash flows: December 31, (in thousands) 2022 2021 Cash and cash equivalents $ 36,194 $ 6,184 Restricted cash 1,523 1,290 Total cash, cash equivalents and restricted cash presented in the consolidated statement of cash flows $ 37,717 $ 7,474 Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoiced amount, do not bear interest, and are typically due 30 days from the invoice date. The Company generally does not require collateral from its customers and maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and the Company’s customers’ financial condition, the amount of accounts receivable in dispute, and the current accounts receivable aging and current payment patterns. Inventory, net In accordance with FASB ASU No. 2015 -11 -in -out Property and Equipment, net Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is calculated using the straight -line Fixed Asset Type Estimated Machinery and equipment 7 Vehicles 5 Computer software 5 Computer equipment 5 Furniture and fixtures 5 Leasehold improvements are amortized over the shorter of the remaining lease term or expected useful lives of the improvements. Long-Lived Assets The Company reviews its long -lived -of-use Deferred Issuance Costs The Company capitalizes costs that are directly associated with in -process recorded as contra -liabilities -term Customer Deposits Customer deposits consists of deposits received by the Company, as required on certain contracts and agreements, which are refundable at the termination of the contract. Product Warranties The Company estimates the cost of its warranty obligations based on several key estimates: the warranty period (generally 20 to 25 years from installation for defects in design, materials, workmanship and manufacture, and generally 10 years from installation for equipment to conform to specifications and drawings applicable under normal use and service), its historical experience of known product failure rates, use of materials to repair or replace defective products and parts, and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise. Should the actual experience relative to these factors differ from the estimates, the Company may be required to record additional warranty reserves. Derivative Instruments The convertible notes issued in January 2020, July 2019 and May 2019 contained embedded derivative instruments, representing contingent redemption options (Note 9). The contingent redemption options met the requirements for separate accounting and were accounted for as a derivative liability and single derivative instrument for each tranche of the convertible notes. The derivative instruments were recorded at fair value at inception and were subject to remeasurement to fair value at each balance sheet date, with any changes in estimated fair value recognized in the accompanying consolidated statements of operations. In 2021, the convertible notes were converted into shares of Series D in conjunction with the sale of such other shares to other investors and the derivative instruments were derecognized on such date (Note 4). There are no convertible notes or derivative instruments outstanding as of December 31, 2022 or 2021. Convertible Preferred Stock Warrants Freestanding warrants to purchase the Company’s convertible preferred stock are classified as liabilities on the accompanying consolidated balance sheets. The convertible preferred stock warrants are recorded as liabilities because the underlying shares of convertible preferred stock are contingently redeemable upon a deemed liquidation event. The warrants are recorded at estimated fair value and are subject to remeasurement at each balance sheet date and recorded in change in fair value of preferred stock warrant liability in the accompanying consolidated statements of operations. Revenue Recognition The Company complies with ASC Topic 606, Revenue from Contracts with Customers The Company determines revenue recognition through the following steps: • • • • • The Company’s primary source of revenue is the sale of its hardware products. The Company’s hardware products are fully functional at the time of shipment and do not require modification or customization for customers to use the products. The Company sells its products primarily to distributors that resell the Company’s products to end users. Distributors do not have general rights of return and generally order goods for immediate resale to end customers. The Company uses present right to payment and transfer of title as indicators to determine the transfer of control to the customer. The Company recognizes revenue at a point in time when its performance obligation has been satisfied and control of the product is transferred to the customer, which generally aligns with shipping terms. Contract shipping terms include ExWorks (“EXW”), FOB Shipping Point and FOB Destination incoterms. Under EXW (meaning the seller fulfills its obligation to deliver when it makes goods available at its premises, or another specified location, for the buyer to collect), the performance obligation is satisfied and control is transferred at the point when the customer is notified that their order is available for pickup. Under FOB Shipping Point, control is transferred to the customer at the time the good is transferred to the shipper and under FOB Destination, at the time the customer receives the goods. We deduct sales returns to arrive at revenue, net. Sales tax and other similar taxes are excluded from revenues. The Company has made the election to account for shipping and handling as activities to fulfill the promise to transfer the product and as such records amounts charged to customers for shipping and handling as revenue and the related costs are included in cost of revenues. The Company typically incurs incremental costs to acquire customer contracts in the form of sales commissions; however, because the expected benefit from these contracts is one year or less, we expense these amounts as incurred. Product warranty costs are recorded as expense to cost of revenue based on customer history, historical information and current trends. Sales of the Company’s hardware products include the Company’s web -based Deferred revenue or contract liabilities consists of payments received from customers in advance of revenue recognition for the Company’s products and service. The current portion of deferred revenue represents the unearned revenue that will be earned within 12 months of the balance sheet date. Correspondingly, noncurrent deferred revenue represents the unearned revenue that will be earned after 12 months from the balance sheet date. Customer deposits are recorded in accrued expenses and other current liabilities within the consolidated balance sheet. The following table summarizes the changes in deferred revenue and customer deposits: Year Ended December 31, (in thousands) 2022 2021 Balance at January 1 $ 232 $ 250 Deferral of revenue 20,327 50 Recognition of unearned revenue (19,437 ) (68 ) Balance at December 31 $ 1,122 $ 232 As of December 31, 2022, the Company expects to recognize $1.1 million from remaining performance obligations over a weighted average term of 2 years. Cost of Revenue The Company includes the following in cost of revenue: product costs, warranty costs, manufacturing personnel and logistics costs, inventory reserve charges, shipping and handling costs, hosting service costs related to the monitoring service, and depreciation and amortization of manufacturing test equipment.

The Company determines whether an arrangement is or contains a lease, its classification, and its term at the lease commencement date. Leases with a term greater than one year will be recognized on the consolidated balance sheet as ROU assets, current lease liabilities, and if applicable, long -term incurred. The discount rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rates, which are the rates that would be incurred to borrow on a collateralized basis, over similar terms, amounts equal to the lease payments in a similar economic environment. If significant events, changes in circumstances, or other events indicate that the lease term or other inputs have changed, the Company would reassess lease classification, remeasure the lease liability using revised inputs as of the reassessment date, and adjust the ROU assets. Lease expense is recognized on a straight -line As permitted under the new guidance, the Company elected the package of practical expedients, which allowed the Company to retain prior conclusions regarding lease identification, classification and initial direct costs. For the Company’s lease agreements with lease and non -lease -term As of their January 1, 2022 adoption, the Company recorded operating lease ROU assets and lease liabilities of $1.5 million and $1.7 million, respectively. The Company’s adoption of this standard did not result in a cumulative effect adjustment being recorded to accumulated deficit as of January 1, 2022 and did not have a material impact on the Company’s consolidated statements of operations. Revision of Prior Period Financial Statements During 2022, the Company identified immaterial errors in its previously issued 2021 consolidated financial statements resulting from the exclusion of cumulative dividends, related to convertible preferred stockholders, in the calculation of the Company’s net loss attributable to common stockholders. This occurred for the year ended December 31, 2021, thereby understating net loss attributable to common stockholders and net loss per share of common stock.

Summary of Significant Accounting Policies	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10 -Q -X The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10 -K Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes -Oxley Further, Section 102(b)(l) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non -emerging Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires the Company’s 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. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short -term Cash and Marketable Securities Held in Trust Account At March 31, 2023 all of the assets held in the Trust account were held in money market funds which are invested primarily in U.S. Treasury Securities. At December 31, 2022, all of the assets held in the Trust Account were held in cash. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these investments are included in interest earned on marketable securities held in Trust Account in the accompanying statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information. Offering Costs Offering costs consist of underwriting, legal, accounting and other expenses incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs amounted to $1,646,673, which were initially charged to temporary equity and then accreted to common stock subject to redemption upon the completion of the Initial Public Offering. Common Stock Subject to Possible Redemption The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”), Topic 480 “Distinguishing Liabilities from Equity.” Shares of common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption right that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. In connection with the stockholders vote at the Special Meeting of Stockholders held by the Company on December 20, 2022, 9,121,751 Accordingly, at March 31, 2023 and December 31, 2022, 2,378,249 The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable common stock to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable common stock resulted in a charge against additional paid -in At March 31, 2023 and December 31, 2022, the common stock subject to possible redemption reflected in the balance sheets was reconciled in the following table: Common stock subject to possible redemption, December 31, 2021 $ 116,725,000 Less: Redemption of 9,121,751 shares (93,419,442 ) Extension payment (135,440 ) Plus: Remeasurement of carrying value to redemption value 1,152,044 Common stock subject to possible redemption, December 31, 2022 $ 24,322,162 Less: Extension payment (163,181 ) Plus: Remeasurement of carrying value to redemption value 326,452 Common stock subject to possible redemption, March 31, 2023 $ 24,485,433 Warrant Classification The Company accounts for warrants as either equity -classified -classified -in each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non -cash Income Taxes The Company accounts for income taxes under ASC 740, “Income Taxes.” ASC 740, Income Taxes, requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the unaudited condensed consolidated financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. As of March 31, 2023 and December 31, 2022, the Company’s deferred tax asset had a full valuation allowance recorded against it. The Company’s effective tax rate was (18.06%) and 0.00% for the three months ended March 31, 2023 and 2022, respectively. The effective tax rate differs from the statutory tax rate of 21% for the three months ended March 31, 2023 due to the permanent difference on M&A Expenses and the increase in the valuation allowance on the deferred tax assets. and the effective tax rate differs from the statutory rate of 21% for the three months ended March 31, 2022, due to the valuation allowance on the deferred tax assets. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more -likely-than-not The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of March 31, 2023 and December 31, 2022. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company has identified the United States as its only “major” tax jurisdiction. The Company is subject to income taxation by major taxing authorities since inception. These examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal and state tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Net Loss per Common Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of common stock, which are referred to as redeemable common stock and non -redeemable The calculation of diluted loss per common share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 5,980,750 other contracts that could, potentially, be exercised or converted into common stocks and then share in the earnings of the Company. As a result, diluted net loss per common share is the same as basic net loss per common share for the periods presented. The following tables reflect the calculation of basic and diluted net loss per common share (in dollars, except per share amounts): For the Three Months Ended March 31, 2023 2022 Redeemable Non-redeemable Redeemable Non-redeemable Basic and diluted net loss per common share Numerator: Allocation of net loss $ (171,076 ) $ (240,006 ) $ (94,275 ) $ (27,352 ) Denominator: Basic and diluted weighted average shares outstanding 2,378,249 3,336,500 11,500,000 3,336,500 Basic and diluted net loss per common share $ (0.07 ) $ (0.07 ) $ (0.01 ) $ (0.01 ) Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times may exceed the Federal Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on these accounts. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short -term Recent Accounting Standards In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020 -06 -20 -40 -06 -06 -06 -06 -06 Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.

FAIR VALUE MEASUREMENTS The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re -measured -financial -measured The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability. The following table presents information about the Company’s assets that are measured at fair value on a recurring basis at March 31, 2023 and December 31, 2022 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Description Level December 31, March 31, Assets: Cash and Marketable securities held in Trust Account 1 $ 24,678,170 $ 24,601,832	NOTE 9.

Disclosure Text Block [Abstract]
Leases	10. Leases Operating Leases As a lessee, the Company currently leases office space and vehicles in the United States, Italy, Israel, China, and Thailand. All of the Company leases are classified as operating leases. The Company has no leases classified as finance or sales -type When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of its leases do not provide a readily determinable implicit rate. Therefore, the Company must estimate its incremental borrowing rate to discount the lease payments based on information available at lease commencement. The majority of the Company’s leases have remaining lease terms of one to seven years, some of which include options to extend the leases for up to eight years, and some of which include options to terminate the leases within one year. The components of lease expense are as follows (in thousands): (in thousands) Three Months Operating lease costs $ 194 Variable lease costs 62 Total lease cost $ 256 Other information related to leases was as follows: Supplemental Cash Flows Information (in thousands) Three Months Cash paid for amounts included in the measurement of lease liabilities $ 174 March 31, December 31, Weighted average remaining lease term (years) 3.7 2.7 Weighted average discount rate 5.0 % 5.4 % Future maturities of lease liabilities were as follows as of March 31, 2023: Years Ending December 31 (Unaudited) (in thousands): Operating 2023 (Excluding the three months ended March 31, 2023) $ 652 2024 866 2025 359 2026 348 2027 340 Thereafter 145 Total future minimum lease payments $ 2,710 Less: imputed interest 253 Present value of lease liabilities $ 2,457	10. Leases Operating Leases As discussed in Recently Adopted Accounting Guidance, effective January 1, 2022 the Company adopted accounting guidance, ASC Topic 842, issued by the FASB related to leases that outlines a comprehensive lease accounting model and supersedes the current lease guidance. The Company adopted this guidance using the modified retrospective approach and elected the optional transition method. As a result, comparative periods in the Company’s financial statements are not adjusted for the impacts of the new standard. The Company routinely enters into operating leases for office spaces and vehicles. The Company determines if a contract is or contains a lease based on its relevant terms in accordance with ASC Topic 842, including whether it conveys to the Company the right to obtain substantially all the economic benefits of the identified leased asset and to direct its use. ROU 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. The Company’s ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of fixed lease payments over the lease term. The Company is also responsible for payment of certain real estate taxes, insurance and other expenses on certain of its leases. These amounts are generally considered to be variable lease costs and are not included in the measurement of the ROU assets and lease liabilities, but are expensed as incurred. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise any such option. Lease costs are recognized on a straight -line The elements of the lease costs were as follows (in thousands): Year Ended December 31, 2022 Operating lease cost $ 614 Variable lease cost 277 Total lease cost $ 891 Lease term and discount rate information related to leases was as follows: Year Ended Weighted-average remaining lease term (in years) Operating leases 2.7 Weighted-average discount rate Operating leases 5.4 % Supplemental cash flow information (in thousands): Year Ended Cash paid for: Operating cash flows from operating leases $ 637 Operating lease right of use assets obtained in exchange for operating lease liabilities (1) $ 1,787 ____________ (1) Future maturities of lease liabilities were as follows as of December 31, 2022 (in thousands): Year ending December 31,: Operating 2023 $ 636 2024 580 2025 84 2026 62 2027 46 Thereafter 40 Total future minimum payments 1,448 Less imputed interest (108 ) Present value of lease liabilities $ 1,340 As previously disclosed in the 2021 consolidated financial statements and under and under ASC Topic 840, Leases, Years Ending December 31 (in thousands): 2022 $ 2023 444 2024 457 2025 117 $ 1,449

Business Combinations [Abstract]
Business Combinations	12. Business Combinations On January 27, 2023 (“Closing Date”), the Company acquired 100% of the equity interests of fSight. The results of fSight’s operations have been included in the unaudited condensed consolidated interim financial statements since the Closing Date. fSight primarily focuses on developing and marketing a software as a service platform, based on artificial intelligence for the smart management of electrical energy. The acquisition expands the Company’s ability to leverage energy consumption and production data for solar energy producers, adding a prediction platform that provides actionable system performance data, from the grid down to the module level. Under the terms of the purchase agreement, total consideration consisted of 5,598,751 Business Combinations -related three months ended March 31, 2023, which were expensed as incurred in the condensed consolidated statement of operations and comprehensive income (loss). The contingent shares were recorded as a liability at a fair value of approximately $2.0 million on the Closing Date based on the fair value of the Company’s common stock at the Closing Date. The current portion of the contingent shares liability is recorded in accrued expenses and other current liabilities and the non -current -term The following table summarizes the provisional fair values of the identifiable assets acquired and liabilities assumed at the date of the acquisition: (in thousands) As of Consideration transferred: Fair value of common stock issued $ 10,078 Fair value of contingent shares 1,990 Total consideration $ 12,068 Assets Acquired Cash and cash receivables $ 55 Accounts receivable 117 Property and equipment 9 Intangibles assets 2,000 Goodwill 11,996 Total assets acquired $ 14,177 Liabilities Assumed Accounts payable $ 418 Accrued Expenses 294 Convertible loans 527 Other current liabilities 89 Other long-term liabilities 781 Net assets acquired $ 12,068 The amounts above represent the Company’s provisional fair value estimates related to the acquisition as of January 27, 2023 and are subject to subsequent adjustments as additional information is obtained during the applicable measurement period. The primary areas of estimates that are not yet finalized include certain tangible assets acquired and liabilities assumed, as well as the identifiable intangible assets. The purchase price was allocated to the tangible assets and identifiable intangible assets acquired and liabilities assumed based on their acquisition date estimated fair values. Accounts receivable and property and equipment acquired were not material in size or scope, and the carrying amounts of these assets represented their fair value. The identifiable intangible assets consist of trade names, developed technology, and customer relationships which were assigned fair values of approximately $10,000, $1.8 million and $0.2 million, respectively. The trade names, developed technology, and customer relationships are all being amortized on a straight -lined The trade names were valued using the relief from royalty method, the developed technology was valued using the multiperiod excess earnings method and the customer relationships were valued using the distributor method. Each method requires several judgments and assumptions to determine the fair value of intangible assets, including revenue growth rates, discount rates, earnings before interest, taxes, depreciation, and amortization margins, and tax rates, among others. These nonrecurring fair value measurements are Level 3 measurements within the fair value hierarchy. Goodwill represents the excess of the purchase price over the identifiable tangible and intangible assets acquired in addition to liabilities assumed arising from the business combination. The Company believes the goodwill related to the acquisition was attributable to the expected synergies, value of the assembled workforce, and the collective experience of the management team with regards to its operations, customers, and industry. Supplemental Pro Forma Information (Unaudited) The selected financial data with respect to the revenue and earnings on a pro forma consolidated basis as if the acquisition of fSight occurred on January 1, 2022 has been omitted as it was impracticable to make the necessary adjustments to prepare the acquired entity’s financial statements in accordance with GAAP for the year ended December 31, 2022 in a timely manner as the acquired entity was a privately held international organization for which financial statements were not prepared under GAAP. Supplemental Information of Operating Results (Unaudited) For the three months ended March 31, 2023, the Company’s unaudited condensed consolidated interim statement of operations included net revenues of $0.1 million and a net loss of $0.3 million attributable to fSight for the period beginning January 1, 2023 through March 31, 2023.

Income Taxes [Line Items]
Income Taxes	13. Income Taxes The income tax provision is calculated for an interim period by distinguishing between elements recognized in the income tax provision through applying an estimated annual effective tax rate (the “ETR”) to a measure of year -to-date -to-date -to-date -270-30-36 -period -to-date	14. Income Taxes The Company’s geographical breakdown of its income before provision for income taxes is as follows: (in thousands) Year Ended December 31, 2022 2021 Domestic $ (7,179 ) $ (4,826 ) Foreign 213 163 Loss before for income tax expense $ (6,966 ) $ (4,663 ) The provision for income taxes during the years ended December 31, 2022 and 2021 represents primarily income tax expense for the operations of the Company’s foreign subsidiaries. Due to the Company’s net losses, no other income tax provision or benefit has been recorded. The reconciliation of the provision computed at the federal statutory rate to the Company’s provision (benefit) for income taxes was as follows: (in thousands except for percentages) Year Ended December 31, 2022 2021 Tax at federal statutory rate 21.0 % 21.0 % State tax, net of federal benefit 1.6 % 6.4 % Embedded derivative adjustments 0.0 % (1.8 )% Research and development credits 2.4 % 3.0 % Mark to market adjustments (3.1 )% (0.9 )% PPP loan forgiveness income 0.0 % 8.1 % Transaction costs 0.0 % 0.0 % Stock based compensation (1.2 )% 0.0 % Other (0.4 )% (6.9 )% Change in valuation allowance (21.3 )% (33.4 )% (1.0 )% (4.4 )% During the years ended December 31, 2022 and 2021 the Company recorded total income tax expense of $0.1 and $0.2 million, respectively, related to foreign earnings. Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The components of deferred tax assets and liabilities are as follows: December 31, (in thousands) 2022 2021 Deferred tax assets: Net operating loss carryforwards $ 17,360 $ 17,619 Research and development tax credits 2,157 1,875 Stock compensation 246 221 Capitalized research costs 1,338 — Lease liability 299 — Other timing differences 1,535 1,407 Gross deferred tax assets 22,935 21,122 Less: valuation allowance (22,608 ) (21,122 ) $ 327 $ — Deferred tax liabilities Fixed assets $ (50 ) $ — Right of use assets (277 ) — Net deferred tax asset $ — $ — Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. The Company could not conclude that it was more likely than not that tax benefits from operating losses would be realized and, accordingly, has provided a full valuation allowance against its deferred tax assets. Accordingly, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $1.5 million and $1.6 million during the years ended December 31, 2022 and 2021, respectively due to current year losses and research and development credits generated. At December 31, 2022, the Company has federal and state net operating loss carryforwards of approximately $123.0 million and $101.6 million, respectively, available to reduce future taxable income which will begin to expire in 2028 for federal and state income tax purposes. Approximately $27.7 million of federal net operating loss included above can be carried forward indefinitely. At December 31, 2021 the Company had federal and state net operating loss carryforwards of approximately $124.5 million and $100.8 million, respectively. At December 31, 2022, the Company also has federal and California research and development income tax credit carryforwards of $2.5 million and $2.1 million, respectively At December 31, 2021, the Company also has federal and California research and development income tax credit carryforwards of $2.2 million and $1.9 million, respectively. The federal income tax credit carryforwards begin to expire in 2029, while the California income tax credit carry forward indefinitely. The Company also has foreign tax credit carryforwards of $0.2 million for years ended December 31, 2022 and 2021. The foreign tax credit carryforwards begin to expire in 2024. The Company believes a portion of its net operating loss and research and development carryforwards may be unavailable. Under the provisions of Section 382 of the Internal Revenue Code of 1986, it appears more likely than not that an ownership change occurred in April 2013. As a result, pre -change -change A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows: December 31, (in thousands) 2022 2021 Balance at beginning of year $ 819 $ 694 Additions based on tax positions related to the current year 133 125 Balance at end of year $ 952 $ 819 At December 31, 2022 and 2021, the balance of gross uncertain income tax benefits was $1.0 million and $0.8 million, respectively. For each of the years ended December 31, 2022 and 2021, the balance of gross uncertain tax benefits increased $0.1 million and $0.1 million, respectively, related to research and development income tax credits claimed. All of these unrecognized tax benefits would, if recognized, reduce the Company’s annual effective tax rate. However, the Company currently has a full valuation allowance against its U.S. net deferred tax assets, which would impact the timing of the effective tax rate benefit should any of these uncertain tax positions be favorably settled in the future. The Company does not anticipate a significant change to the total amount of unrecognized tax benefits within the next twelve months. The Company files income tax returns in the U.S. federal, California and other various state and international jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations, and require significant judgment to apply. Carryover attributes beginning in 2007 remain open to adjustment by the U.S. and state authorities. The U.S., state, and foreign jurisdictions have statutes of limitations that generally range from three to five years. Due to the Company’s net losses, substantially all of its federal and state income tax returns are subject to examination for federal and state purposes since inception. As of December 31, 2022, there were no ongoing examinations. The Company does not anticipate significant changes to its current uncertain tax positions through December 31, 2023. The Company recognizes any interest and/or penalties related to income tax matters as a component of income tax expense. As of December 31, 2022, there were no accrued interest and penalties related to uncertain tax positions.

Income Taxes		NOTE 8. INCOME TAX The income tax provision for the years ended December 31, 2022 and 2021 consisted of the following: December 31, 2022 December 31, 2021 Federal Current $ 395,019 $ — Deferred (109,249 ) (84,534 ) State and Local Current — — Deferred (64,545 ) — Change in valuation allowance 173,794 84,534 Income tax provision $ 395,019 $ — The Company’s net deferred tax assets at December 31, 2022 and 2021 were as follows: December 31, 2021 December 31, 2020 Deferred tax assets Net operating loss carryforward $ — $ 30,909 Startup/Organizational expenses 258,742 54,038 Total deferred tax assets 258,742 84,947 Valuation allowance (258,742 ) (84,947 ) Deferred tax assets, net of valuation allowance $ — $ — As of December 31, 2022 and 2021, the Company had $0 and $147,184 of U.S. federal net operating loss carryovers available to offset future taxable income. In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2022, the change in the valuation allowance was $173,794. For the year ended December 31, 2021, the change in the valuation allowance was $84,534. A reconciliation of the federal income tax rate to the Company’s effective tax rate at December 31, 2022 and 2021 was as follows: December 31, 2022 December 31, 2021 Statutory federal income tax rate 21.00 % 21.00 % State taxes, net of federal tax benefit 6.98 % 0.00 % M&A expenses 87.0 % 0.00 % Franchise tax interest 0.07 % 0.00 % Valuation allowance 67.10 % (21.00 )% Income tax provision 182.20 % 0.00 % The Company files income tax returns in the U.S. federal jurisdiction and is subject to examination by the various taxing authorities. The Company’s tax returns for the years ended December 31, 2022 and 2021 remain open and subject to examination.

The goodwill arising from the Company’s acquisition is attributable to the value of the potential expanded market opportunity with new customers. The goodwill balance as of March 31, 2023 relates to the Company’s purchase of fSight. Intangible assets have either an identifiable or indefinite useful life. Intangible assets are recorded at cost or when acquired as part of a business combination at estimated fair value. Intangible assets with identifiable useful lives are amortized on a straight -line Goodwill is not amortized but is subject to annual impairment testing unless circumstances dictate more frequent assessments. The Company will perform an annual impairment assessment for goodwill and more frequently whenever events or changes in circumstances indicate that the fair value of the asset may be less than the carrying amount.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company uses a three -level -based -specific defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with those financial instruments. The three -level • Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. • Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liabilities. • Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

Revenue Recognition	Revenue Recognition The Company follows ASC Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”) for revenue recognition. In accounting for contracts with customers: The Company determines revenue recognition through the following steps: • • • • • The Company’s primary source of revenue is the sale of its hardware products. The Company’s hardware products are fully functional at the time of shipment and do not require modification or customization for customers to use the products. The Company sells its products primarily to distributors that resell the Company’s products to end users. Distributors do not have general rights of return and generally order goods for immediate resale to end customers. The Company uses present right to payment and transfer of title as indicators to determine the transfer of control to the customer. The Company recognizes revenue at a point in time when its performance obligation has been satisfied and control of the product is transferred to the customer, which generally aligns with shipping terms. Contract shipping terms include ExWorks (“EXW”), FOB Shipping Point and FOB Destination incoterms. Under EXW (meaning the seller fulfills its obligation to deliver when it makes goods available at its premises, or another specified location, for the buyer to collect), the performance obligation is satisfied and control is transferred at the point when the customer is notified that their order is available for pickup. Under FOB Shipping Point, control is transferred to the customer at the time the good is transferred to the shipper and under FOB Destination, at the time the customer receives the goods. The Company deduct sales returns to arrive at revenue, net. Sales tax and other similar taxes are excluded from revenues. The Company has made the election to account for shipping and handling as activities to fulfill the promise to transfer the product and as such records amounts charged to customers for shipping and handling as revenue and the related costs are included in cost of revenues. The Company typically incurs incremental costs to acquire customer contracts in the form of sales commissions; however, because the expected benefit from these contracts is one year or less, the Company expenses these amounts as incurred. Product warranty costs are recorded as expense to cost of revenue based on customer history, historical information and current trends. Sales of the Company’s hardware products include the Company’s web -based Deferred revenue or contract liabilities consists of payments received from customers in advance of revenue recognition for the Company’s products and service. The current portion of deferred revenue represents the unearned revenue that will be earned within 12 months of the balance sheet date. Correspondingly, noncurrent deferred revenue represents the unearned revenue that will be earned after 12 months from the balance sheet date. The following table summarizes the changes in deferred revenue: Three Months Ended (in thousands) 2023 2022 Balance at the beginning of the period $ 1,122 $ 232 Deferral of revenue 12,198 2,285 Recognition of unearned revenue (11,712 ) (1,666 ) Balance at the end of the period $ 1,608 $ 851 As of March 31, 2023, the Company expects to recognize $1.6 million from remaining performance obligations over a weighted average term of 1.7 years. The Company recognized approximately $0.7 million and $0.2 million in revenue that was included in the beginning contract liabilities balance during the three months ended March 31, 2023 and 2022, respectively.

Use of Estimates		Use of Estimates The preparation of the consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates due to risk and uncertainties, including uncertainty in the current economic environment due to the global impact of COVID -19 -lived -based
Risks and Uncertainties		Risks and Uncertainties The Company is subject to a number of risks inherent in a business without substantial operating history, including, but not limited to, new and evolving markets, advances and trends in the development of new technology and services and regulations thereon, unfavorable economic and market conditions, competition from other companies with longer operating histories and greater financial resources, the ability to obtain adequate funding, dependence on key employees and the ability to attract and retain qualified employees.
Concentration of Credit Risk		Concentrations of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash, restricted cash, and accounts receivable. The Company maintains deposits in federally insured financial institutions, which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant credit risk beyond the normal credit risk associated with commercial banking relationships as the Company’s cash and restricted cash are deposited with major financial institutions in the U.S., Europe, the Middle East and Asia. At December 31, 2022 and 2021, the Company held insignificant cash in foreign bank accounts. To date, the Company has not experienced any losses on its deposits of cash. During the year ended December 31, 2022, there was one individual customer that exceeded 10% of the Company’s annual revenue, net. This customer accounted for 10.6% of revenue, net. Accounts receivable from this customer represented $2.1 million. During the year ended December 31, 2021, there was one individual customer that exceeded 10% of the Company’s annual revenue, net. This customer accounted for 14% of revenue, net. Accounts receivable from this customer represented $0.5 million.
Segment Information		Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker (“CODM”), or decision- making group, in deciding how to allocate resources and in assessing performance. The CODM is the Company’s Chief Executive Officer. The Company views and manages its operations as a single operating segment.
Foreign Operations		Foreign Operations Operations outside the U.S. include subsidiaries in Israel, Italy and China. Foreign operations are subject to risks inherent in operating under different legal systems and various political and economic environments. Among those risks are changes in existing tax laws, possible limitations on foreign investment and income repatriation, government price or foreign exchange controls, and restrictions on currency exchange. Net liabilities of foreign operations were $0.7 million and $0.2 million at December 31, 2022 and 2021, respectively. Revenue, net from foreign customers represented 73% and 61% of revenue, during the years ended December 31, 2022 and 2021, respectively. There were two foreign countries individually representing greater than 10% of revenue, net during the year ended December 31, 2022 and totaled 37% of revenue, net. There were two foreign countries individually representing greater than 10% of revenue, net during the year ended December 31, 2021 and totaled 27% of revenue, net. Accounts receivable due from foreign customers was 80% and 65% of total accounts receivable at December 31, 2022 and 2021, respectively.
Restricted Cash and Reconciliation to the Consolidated Statements of Cash Flows		Restricted Cash and Reconciliation to the Consolidated Statements of Cash Flows Restricted cash represents amounts held on deposit at a commercial bank used to secure the Company’s Senior Bonds (Note 9). The following table provides a reconciliation of the components of cash and cash equivalents and restricted cash reported in the Company’s consolidated balance sheets to the total of the amount presented in the consolidated statements of cash flows: December 31, (in thousands) 2022 2021 Cash and cash equivalents $ 36,194 $ 6,184 Restricted cash 1,523 1,290 Total cash, cash equivalents and restricted cash presented in the consolidated statement of cash flows $ 37,717 $ 7,474
Accounts Receivable and Allowance for Doubtful Accounts		Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoiced amount, do not bear interest, and are typically due 30 days from the invoice date. The Company generally does not require collateral from its customers and maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and the Company’s customers’ financial condition, the amount of accounts receivable in dispute, and the current accounts receivable aging and current payment patterns.
Inventory, net		Inventory, net In accordance with FASB ASU No. 2015 -11 -in -out

Customer Deposits		Customer Deposits Customer deposits consists of deposits received by the Company, as required on certain contracts and agreements, which are refundable at the termination of the contract.
Product Warranties		Product Warranties The Company estimates the cost of its warranty obligations based on several key estimates: the warranty period (generally 20 to 25 years from installation for defects in design, materials, workmanship and manufacture, and generally 10 years from installation for equipment to conform to specifications and drawings applicable under normal use and service), its historical experience of known product failure rates, use of materials to repair or replace defective products and parts, and service delivery costs incurred in correcting product failures. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise. Should the actual experience relative to these factors differ from the estimates, the Company may be required to record additional warranty reserves.
Derivative Instruments		Derivative Instruments The convertible notes issued in January 2020, July 2019 and May 2019 contained embedded derivative instruments, representing contingent redemption options (Note 9). The contingent redemption options met the requirements for separate accounting and were accounted for as a derivative liability and single derivative instrument for each tranche of the convertible notes. The derivative instruments were recorded at fair value at inception and were subject to remeasurement to fair value at each balance sheet date, with any changes in estimated fair value recognized in the accompanying consolidated statements of operations. In 2021, the convertible notes were converted into shares of Series D in conjunction with the sale of such other shares to other investors and the derivative instruments were derecognized on such date (Note 4). There are no convertible notes or derivative instruments outstanding as of December 31, 2022 or 2021.
Convertible Preferred Stock Warrants		Convertible Preferred Stock Warrants Freestanding warrants to purchase the Company’s convertible preferred stock are classified as liabilities on the accompanying consolidated balance sheets. The convertible preferred stock warrants are recorded as liabilities because the underlying shares of convertible preferred stock are contingently redeemable upon a deemed liquidation event. The warrants are recorded at estimated fair value and are subject to remeasurement at each balance sheet date and recorded in change in fair value of preferred stock warrant liability in the accompanying consolidated statements of operations.
Cost of Revenue		Cost of Revenue The Company includes the following in cost of revenue: product costs, warranty costs, manufacturing personnel and logistics costs, inventory reserve charges, shipping and handling costs, hosting service costs related to the monitoring service, and depreciation and amortization of manufacturing test equipment.

Recently Adopted Accounting Guidance		Recently Adopted Accounting Guidance In August 2020, the FASB issued ASU Update No. 2020 -06 Debt - Debt with Conversion and Other Options (Subtopic 470 -20 ) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815 -40 ): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020 -06 ) -06 . -06 In February 2016, the FASB issued ASU No. 2016 -02 Leases ( -02 -of-use The Company adopted ASC 842 effective as of January 1, 2022, using the modified retrospective approach. The Company determines whether an arrangement is or contains a lease, its classification, and its term at the lease commencement date. Leases with a term greater than one year will be recognized on the consolidated balance sheet as ROU assets, current lease liabilities, and if applicable, long -term incurred. The discount rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rates, which are the rates that would be incurred to borrow on a collateralized basis, over similar terms, amounts equal to the lease payments in a similar economic environment. If significant events, changes in circumstances, or other events indicate that the lease term or other inputs have changed, the Company would reassess lease classification, remeasure the lease liability using revised inputs as of the reassessment date, and adjust the ROU assets. Lease expense is recognized on a straight -line As permitted under the new guidance, the Company elected the package of practical expedients, which allowed the Company to retain prior conclusions regarding lease identification, classification and initial direct costs. For the Company’s lease agreements with lease and non -lease -term As of their January 1, 2022 adoption, the Company recorded operating lease ROU assets and lease liabilities of $1.5 million and $1.7 million, respectively. The Company’s adoption of this standard did not result in a cumulative effect adjustment being recorded to accumulated deficit as of January 1, 2022 and did not have a material impact on the Company’s consolidated statements of operations.
Revision of Prior Period Financial Statements		Revision of Prior Period Financial Statements During 2022, the Company identified immaterial errors in its previously issued 2021 consolidated financial statements resulting from the exclusion of cumulative dividends, related to convertible preferred stockholders, in the calculation of the Company’s net loss attributable to common stockholders. This occurred for the year ended December 31, 2021, thereby understating net loss attributable to common stockholders and net loss per share of common stock.

Net Loss per Common Share	Net Loss per Common Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of common stock, which are referred to as redeemable common stock and non -redeemable The calculation of diluted loss per common share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 5,980,750 other contracts that could, potentially, be exercised or converted into common stocks and then share in the earnings of the Company. As a result, diluted net loss per common share is the same as basic net loss per common share for the periods presented. The following tables reflect the calculation of basic and diluted net loss per common share (in dollars, except per share amounts): For the Three Months Ended March 31, 2023 2022 Redeemable Non-redeemable Redeemable Non-redeemable Basic and diluted net loss per common share Numerator: Allocation of net loss $ (171,076 ) $ (240,006 ) $ (94,275 ) $ (27,352 ) Denominator: Basic and diluted weighted average shares outstanding 2,378,249 3,336,500 11,500,000 3,336,500 Basic and diluted net loss per common share $ (0.07 ) $ (0.07 ) $ (0.01 ) $ (0.01 )	Net Loss per Common Share The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of common stock, which are referred to as redeemable common stock and non -redeemable Net loss per common share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the period.

Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires the Company’s 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. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Income Taxes	Income Taxes The Company accounts for income taxes under ASC 740, “Income Taxes.” ASC 740, Income Taxes, requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the unaudited condensed consolidated financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. As of March 31, 2023 and December 31, 2022, the Company’s deferred tax asset had a full valuation allowance recorded against it.

Income Taxes The Company accounts for income taxes under ASC 740, “Income Taxes.” ASC 740, Income Taxes, requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized. As of December 31, 2022 and 2021, the Company’s deferred tax asset had a full valuation allowance recorded against it. Our effective tax rate was 182.20% and 0.00% for the year ended December 31, 2022 and 2021, respectively. The effective tax rate differs from the statutory tax rate of 21% for the year ended December 31, 2022 and 2021, due to franchise tax interest, state taxes, net of federal tax benefit, merger and acquisition expenses, and the valuation allowance on the deferred tax assets.
