Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	Note 1 — Organization and Business Operations Organization and General Freedom Acquisition I Corp. (the “Company” or “Freedom”) was incorporated in Cayman Islands on December 23, 2020. The Company was formed for the purpose of entering into a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a 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. On October 3, 2022, the Company entered into a Business Combination Agreement with Jupiter Merger Sub I Corp., a Delaware corporation and a wholly owned subsidiary of the Company, Jupiter Merger Sub II LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company, Complete Solar Holding Corporation, a Delaware corporation, and The Solaria Corporation, a Delaware corporation. The Company’s sponsor is Freedom Acquisition I LLC, a Cayman Islands limited liability company (the “Sponsor”). As of December 31, 2022, the Company had not yet commenced any operations. All activity through December 31, 2022, relates to the Company’s formation and the Initial Public Offering (“IPO” or “Initial Public Offering”) described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the IPO and changes in the fair value of warrant liabilities. Financing The registration statement for the Company’s IPO was declared effective on February 25, 2021 (the “Effective Date”). On March 2, 2021, the Company consummated the IPO of 34,500,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “public share”), at $10.00 per Unit, generating gross proceeds of $345,000,000, which is discussed in Note 4. Simultaneously with the closing of the IPO, the Company consummated the sale of 6,266,667 warrants (the “Private Placement Warrants”), at a price of $1.50 per Private Placement Warrant, which is discussed in Note 5. Transaction costs amounted to $19,175,922, consisting of $6,405,000 of underwriting fees, $12,075,000 of deferred underwriting fees and $695,922 of other offering costs. Of the total transaction cost, $575,278 was expensed as non-operating expenses in the consolidated statement of operations with the rest of the offering cost charged to shareholders’ deficit for the year ended December 31, 2021. The transaction costs were allocated based on the relative fair value basis, compared to the total offering proceeds, between the fair value of the public warrant liabilities and the Class A ordinary shares. Trust Account Following the closing of the IPO on March 2, 2021, an amount of $345,000,000 from the net proceeds of the sale of the Units in the IPO and the sale of the Private Placement Warrants was placed in a trust account (“Trust Account”). The funds in the Trust Account have, since the IPO and until the 24-month anniversary of the consummation of the IPO, been invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company. To mitigate the risk of the Company being deemed to have been operating as an unregistered investment company, prior to the 24-month anniversary of the consummation of the IPO, the Company instructed Continental, the trustee with respect to the Trust Account, to liquidate the U.S. government treasury obligations or money market funds held in the Trust Account and to hold all the funds in the Trust Account in cash in a bank deposit account. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its tax obligations, the proceeds from the IPO and the sale of the private placement units will not be released from the Trust Account until the earliest of (a) the completion of the Company’s initial Business Combination, (b) the redemption of any public shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated certificate of incorporation, and (c) the redemption of the Company’s public shares if the Company is unable to complete the initial Business Combination during the Combination Period (as defined below), subject to applicable law. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders. Initial Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO, although substantially all of the net proceeds are intended to be generally applied toward consummating a Business Combination. The Company’s Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (net of taxes payable) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination. The Company will provide its public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial Business Combination either (i) in connection with a shareholder meeting called to approve the initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account (initially $10.00 per 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). The Class A ordinary shares subject to redemption are recorded at redemption value and classified as temporary equity upon the completion of the IPO, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” In such case, 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 consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the issued and outstanding shares voted are voted in favor of the Business Combination. On February 28, 2023, the Company’s shareholders approved an amendment to its amended and restated memorandum and articles of association to extend the date by which the Company must complete a Business Combination from March 2, 2023 to June 2, 2023, and to thereafter further extend such period up to three times by an additional one month each time (up to September 2, 2023) (such period, as may be extended, the “Combination Period”). However, if the Company is unable to complete a Business Combination within the Combination Period, the Company will redeem 100% of the outstanding public shares for a pro rata portion of the funds held in the Trust Account, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company, divided by the number of then outstanding public shares, subject to applicable law and as further described in the registration statement, and then seek to dissolve and liquidate. The Company’s Sponsor, officers and directors have agreed to (i) waive their redemption rights with respect to their founder shares, private placement shares and public shares in connection with the completion of the initial Business Combination, (ii) waive their redemption rights with respect to their founder shares and public shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation, and (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares and private placement shares if the Company fails to complete the initial Business Combination within the Combination Period. The Company’s Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third-party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked its Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether its Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Company’s Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that its Sponsor would be able to satisfy those obligations. Liquidity As of December 31, 2022, the Company had cash outside the Trust Account of $72,923 available for working capital needs. All remaining cash held in the Trust Account is generally unavailable for the Company’s use prior to an initial Business Combination and is restricted for use either in a Business Combination or to redeem ordinary shares. The Company may elect to withdraw from the interest income earned on the trust account to pay the Company’s tax obligations. As of December 31, 2022, the Company had interest income earned on the trust account of $4,821,632. The Company may raise additional capital through loans or additional investments from the Sponsor or an affiliate of the Sponsor or certain of its directors and officers. The Sponsor may, but is not obligated to, lend the Company funds, from time to time in whatever amounts it deems reasonable in its sole discretion, to meet the Company’s working capital needs. There can be no assurance that the Company will be able to obtain additional financing, however. Moreover, the Company may need to obtain additional financing either to complete its Business Combination or because the Company becomes obligated to redeem a significant number of its public shares upon consummation of its Business Combination, in which case the Company may issue additional securities or incur debt in connection with such Business Combination. Subject to compliance with applicable securities laws, the Company would only complete such financing simultaneously with the completion of its Business Combination. 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. Going Concern In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) Topic 205-40, “Presentation of Financial Statements – Going Concern,” pursuant to its Amended and Restated Certificate of Incorporation, the Company has until the end of the Combination Period to consummate a Business Combination. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution of the Company. Although the Company intends to consummate a Business Combination during the Combination Period, it is uncertain that the Company will be able to do so. This, as well as its liquidity condition, raise 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 at the end of the Combination Period. Risks and Uncertainties Management is currently evaluating the impact of the COVID-19 pandemic and Russia-Ukraine war and has concluded that while it is reasonably possible that the virus and war could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Consideration of IR Act Excise Tax 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 — Organization and Business Operations

Organization and General

Freedom Acquisition I Corp. (the “Company” or “Freedom”) was incorporated in Cayman Islands on December 23, 2020. The Company was formed for the purpose of entering into a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a 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.

On October 3, 2022, the Company entered into a Business Combination Agreement with Jupiter Merger Sub I Corp., a Delaware corporation and a wholly owned subsidiary of the Company, Jupiter Merger Sub II LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company, Complete Solar Holding Corporation, a Delaware corporation, and The Solaria Corporation, a Delaware corporation.

The Company’s sponsor is Freedom Acquisition I LLC, a Cayman Islands limited liability company (the “Sponsor”).

As of December 31, 2022, the Company had not yet commenced any operations. All activity through December 31, 2022, relates to the Company’s formation and the Initial Public Offering (“IPO” or “Initial Public Offering”) described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the IPO and changes in the fair value of warrant liabilities.

Financing

The registration statement for the Company’s IPO was declared effective on February 25, 2021 (the “Effective Date”). On March 2, 2021, the Company consummated the IPO of 34,500,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “public share”), at $10.00 per Unit, generating gross proceeds of $345,000,000, which is discussed in Note 4.

Simultaneously with the closing of the IPO, the Company consummated the sale of 6,266,667 warrants (the “Private Placement Warrants”), at a price of $1.50 per Private Placement Warrant, which is discussed in Note 5.

Transaction costs amounted to $19,175,922, consisting of $6,405,000 of underwriting fees, $12,075,000 of deferred underwriting fees and $695,922 of other offering costs. Of the total transaction cost, $575,278 was expensed as non-operating expenses in the consolidated statement of operations with the rest of the offering cost charged to shareholders’ deficit for the year ended December 31, 2021. The transaction costs were allocated based on the relative fair value basis, compared to the total offering proceeds, between the fair value of the public warrant liabilities and the Class A ordinary shares.

Trust Account

Following the closing of the IPO on March 2, 2021, an amount of $345,000,000 from the net proceeds of the sale of the Units in the IPO and the sale of the Private Placement Warrants was placed in a trust account (“Trust Account”). The funds in the Trust Account have, since the IPO and until the 24-month anniversary of the consummation of the IPO, been invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company. To mitigate the risk of the Company being deemed to have been operating as an unregistered investment company, prior to the 24-month anniversary of the consummation of the IPO, the Company instructed Continental, the trustee with respect to the Trust Account, to liquidate the U.S. government treasury obligations or money market funds held in the Trust Account and to hold all the funds in the Trust Account in cash in a bank deposit account. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its tax obligations, the proceeds from the IPO and the sale of the private placement units will not be released from the Trust Account until the earliest of (a) the completion of the Company’s initial Business Combination, (b) the redemption of any public shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated certificate of incorporation, and (c) the redemption of the Company’s public shares if the Company is unable to complete the initial Business Combination during the Combination Period (as defined below), subject to applicable law. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public shareholders.

Initial Business Combination

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO, although substantially all of the net proceeds are intended to be generally applied toward consummating a Business Combination.

The Company’s Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (net of taxes payable) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company will provide its public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial Business Combination either (i) in connection with a shareholder meeting called to approve the initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed initial Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account (initially $10.00 per 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).

The Class A ordinary shares subject to redemption are recorded at redemption value and classified as temporary equity upon the completion of the IPO, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” In such case, 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 consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the issued and outstanding shares voted are voted in favor of the Business Combination.

On February 28, 2023, the Company’s shareholders approved an amendment to its amended and restated memorandum and articles of association to extend the date by which the Company must complete a Business Combination from March 2, 2023 to June 2, 2023, and to thereafter further extend such period up to three times by an additional one month each time (up to September 2, 2023) (such period, as may be extended, the “Combination Period”). However, if the Company is unable to complete a Business Combination within the Combination Period, the Company will redeem 100% of the outstanding public shares for a pro rata portion of the funds held in the Trust Account, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company, divided by the number of then outstanding public shares, subject to applicable law and as further described in the registration statement, and then seek to dissolve and liquidate.

The Company’s Sponsor, officers and directors have agreed to (i) waive their redemption rights with respect to their founder shares, private placement shares and public shares in connection with the completion of the initial Business Combination, (ii) waive their redemption rights with respect to their founder shares and public shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation, and (iii) waive their rights to liquidating distributions from the Trust Account with respect to their founder shares and private placement shares if the Company fails to complete the initial Business Combination within the Combination Period.

The Company’s Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third-party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, the Company has not asked its Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether its Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Company’s Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that its Sponsor would be able to satisfy those obligations.

Liquidity

As of December 31, 2022, the Company had cash outside the Trust Account of $72,923 available for working capital needs. All remaining cash held in the Trust Account is generally unavailable for the Company’s use prior to an initial Business Combination and is restricted for use either in a Business Combination or to redeem ordinary shares. The Company may elect to withdraw from the interest income earned on the trust account to pay the Company’s tax obligations. As of December 31, 2022, the Company had interest income earned on the trust account of $4,821,632.

The Company may raise additional capital through loans or additional investments from the Sponsor or an affiliate of the Sponsor or certain of its directors and officers. The Sponsor may, but is not obligated to, lend the Company funds, from time to time in whatever amounts it deems reasonable in its sole discretion, to meet the Company’s working capital needs. There can be no assurance that the Company will be able to obtain additional financing, however. Moreover, the Company may need to obtain additional financing either to complete its Business Combination or because the Company becomes obligated to redeem a significant number of its public shares upon consummation of its Business Combination, in which case the Company may issue additional securities or incur debt in connection with such Business Combination. Subject to compliance with applicable securities laws, the Company would only complete such financing simultaneously with the completion of its Business Combination.

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.

Going Concern

In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) Topic 205-40, “Presentation of Financial Statements – Going Concern,” pursuant to its Amended and Restated Certificate of Incorporation, the Company has until the end of the Combination Period to consummate a Business Combination. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution of the Company. Although the Company intends to consummate a Business Combination during the Combination Period, it is uncertain that the Company will be able to do so. This, as well as its liquidity condition, raise 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 at the end of the Combination Period.

Risks and Uncertainties

Management is currently evaluating the impact of the COVID-19 pandemic and Russia-Ukraine war and has concluded that while it is reasonably possible that the virus and war could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Consideration of IR Act Excise Tax

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.
