Organization [Abstract]
Organization	(1) Organization (a) Description of Business Complete Solaria, Inc. (the “Company” or “Complete Solaria”) is a residential solar installer headquartered in Fremont, California, which was formed through Complete Solar Holding Corporation’s acquisition of The Solaria Corporation (“Solaria”). Complete Solar, Inc. (“Complete Solar”) was incorporated in Delaware on February 22, 2010. Through February 2022, the Company operated as a single legal entity as Complete Solar, Inc. In February 2022, the Company implemented a holding company reorganization (the “Reorganization”) in which the Company created and incorporated Complete Solar Holding Corporation (“Complete Solar Holdings”). As a result of the Reorganization, Complete Solar Holdings became the successor entity to Complete Solar, Inc. The capitalization structure was not changed because of the Reorganization as all shares of Complete Solar, Inc common stock and preferred stock were exchanged on a one for one basis with shares of Complete Solar Holdings common stock and preferred stock. The Reorganization was accounted for as a change in reporting entity for entities under common control. The historical assets and liabilities of Complete Solar, Inc. were transferred to Complete Solar Holdings at their carrying value, and there were no changes to net income, other comprehensive income (loss), or any related per share amounts reported in the unaudited condensed consolidated financial statements requiring retrospective application. In October 2022, the Company entered into a business combination agreement, as amended on December 26, 2022 and January 17, 2023 (“Original Business Combination Agreement”) and as amended on May 26, 2023 (“Amended and Restated Business Combination Agreement”), with Jupiter Merger Sub I Corp., a Delaware corporation and a wholly owned subsidiary of Freedom Acquisition I Corp. (“FACT”) (“First Merger Sub”), Jupiter Merger Sub II LLC, a Delaware limited liability company and a wholly owned subsidiary of FACT (“Second Merger Sub”), Complete Solar Holding Corporation, a Delaware corporation, and Solaria, a Delaware corporation. The transactions contemplated by the Amended and Restated Business Combination Agreement were consummated on July 18, 2023 (“Closing Date”). Following the consummation of the Merger on the Closing Date, FACT changed its name to “Complete Solaria, Inc.” As part of the transactions contemplated by the Amended and Restated Business Combination Agreement, FACT effected a deregistration under the Cayman Islands Companies Act and a domestication under Section 388 of the Delaware’s General Corporation Law (the “DGCL” or “Domestication”). On the Closing Date, following the Domestication, First Merger Sub merged with and into Complete Solaria, with Complete Solaria surviving such merger as a wholly owned subsidiary of FACT (the “First Merger”), and immediately following the First Merger, Complete Solaria merged with and into Second Merger Sub, with Second Merger Sub surviving as a wholly owned subsidiary of FACT (the “Second Merger”), and Second Merger Sub changed its name to CS, LLC, and immediately following the Second Merger, Solaria merged with and into a newly formed Delaware limited liability company and wholly-owned subsidiary of FACT and changed its name to The Solaria Corporation LLC (“Third Merger Sub”), with Third Merger Sub surviving as a wholly-owned subsidiary of FACT (the “Additional Merger”, and together with the First Merger and the Second Merger, the “Mergers”). In connection with the closing of the Mergers: ● Each share of the Company’s capital stock, inclusive of shares converted from the 2022 Convertible Notes, issued and outstanding immediately prior to the Closing (“Legacy Complete Solaria Capital Stock”) were cancelled and exchanged into an aggregate of 25,494,332 shares of Complete Solaria Common Stock. ● In July 2023, (i) Meteora Special Opportunity Fund I, LP (“MSOF”), Meteora Capital Partners, LP (“MCP”) and Meteora Select Trading Opportunities Master, LP (“MSTO”) (with MSOF, MCP, and MSTO collectively as “Meteora”); (ii) Polar Multi-Strategy Master Fund (“Polar”), and (iii) Diametric True Alpha Market Neutral Master Fund, LP, Diametric True Alpha Enhanced Market Neutral Master Fund, LP, and Pinebridge Partners Master Fund, LP (collectively, “Sandia”) (together, the “FPA Funding PIPE Investors”) entered into separate subscription agreements (the “FPA Funding Amount PIPE Subscription Agreements”) pursuant to which, the FPA Funding PIPE Investors subscribed for on the Closing Date, an aggregate of 6,300,000 shares of FACT Class A Ordinary Shares, less, in the case of Meteora, 1,161,512 FACT Class A Ordinary Shares purchased by Meteora separately from third parties through a broker in the open market (“Recycled Shares”) in connection with the Forward Purchase Agreements (“FPAs”). Subsequent to the Closing Date, Complete Solaria entered into an additional FPA Funding PIPE Subscription Agreement with Meteora, to subscribe for and purchase, and Complete Solaria agreed to issue and sell, an aggregate of 420,000 shares of Complete Solaria Common Stock. The Company issued shares of Complete Solaria Common Stock underlying the FPAs as of the latter of the closing of the Mergers or execution of the FPAs. ● All certain investors (the “PIPE Investors”) purchased from the Company an aggregate of 1,570,000 shares of Complete Solaria Common Stock (the “PIPE Shares”) for a purchase price of $10.00 per share, for aggregate gross proceeds of $15.7 million (the “PIPE Financing”), including $3.5 million that was funded prior to the Closing Date, pursuant to subscription agreements (the “Subscription Agreements”). At the time of the PIPE Financing, Complete Solaria issued an additional 60,000 shares to certain investors as an incentive to participate in the PIPE Financing. ● On or around the Closing Date, pursuant to the New Money PIPE Subscription Agreements, certain investors affiliated with the New Money PIPE Subscription Agreements (“New Money PIPE Investors”) agreed to subscribe for and purchase, and Complete Solaria agreed to issue and sell to the New Money PIPE Investors an aggregate of 120,000 shares of Complete Solaria Common Stock for a purchase price of $5.00 per share, for aggregate gross proceeds of $0.6 million. Pursuant to its New Money PIPE Subscription Agreement, Complete Solaria issued an additional 60,000 shares of Complete Solaria Common Stock in consideration of certain services provided by it in the structuring of its FPA and the transactions described therein. ● Subsequent to the Closing, Complete Solaria issued an additional 193,976 shares of Complete Solaria Common Stock to the sponsors for reimbursing sponsors’ transfer to certain counterparties and issued an additional 150,000 shares of Complete Solaria Common Stock to an FPA investor for services provided in connection with the Mergers. ● In March 2023, holders of 23,256,504 of the originally issued 34,500,000 FACT Class A Ordinary shares exercised their rights to redeem those shares for cash, and immediately prior to the Closing there were 11,243,496 FACT Class A Ordinary Shares that remained outstanding. At the Closing, holders of 7,784,739 shares of Class A common stock of FACT exercised their rights to redeem those shares for cash, for an aggregate of approximately $82.2 million which was paid to such holders at Closing. The remaining FACT Class A Ordinary Share converted, on a one-for-one basis, into one share of Complete Solaria Common Stock. ● Each issued and outstanding FACT Class B Ordinary Share converted, on a one-for-one basis, into one share of Complete Solaria Common Stock. In November 2022, Complete Solar Holdings acquired Solaria and changed its name to Complete Solaria, Inc. On August 18, 2023, the Company entered into a Non-Binding Letter of Intent to sell certain of Complete Solaria’s North American solar panel assets to Maxeon, Inc. (“Maxeon”). In October 2023, the Company completed the sale of its solar panel business to Maxeon. Refer to Note 1(b) – Divestiture and Note 7 – Divestiture. (b) Divestiture In October 2023, the Company completed the sale of its solar panel business to Maxeon, pursuant to the terms of the Asset Purchase Agreement (the “Disposal Agreement”). Under the terms of the Disposal Agreement, Maxeon agreed to acquire certain assets and employees of Complete Solaria, for an aggregate purchase price of approximately $11.0 million consisting of 1,100,000 shares of Maxeon ordinary shares. As of December 31, 2023, the Company sold all its Maxeon shares and recorded a loss of $4.2 million in its unaudited condensed consolidated statements of operations and comprehensive loss within loss from continuing operations. This divestiture represented a strategic shift in Complete Solaria’s business and qualified as held for sale and as a discontinued operation. Based on the held for sale classification of the assets, the Company reduced the carrying value of the disposal group to its fair value, less its cost to sell and recorded an impairment loss associated with the held for sale intangible assets and goodwill. As a result, the Company classified the results of its solar panel business in discontinued operations in its unaudited condensed consolidated statements of operations and comprehensive loss for all periods presented. The cash flows related to discontinued operations were segregated from continuing operations within the unaudited condensed consolidated statements of cash flows for all periods presented. Unless otherwise noted, discussion within the notes to the unaudited condensed consolidated financial statements relates to continuing operations only and excludes the historical activities of the North American panel business. See Note 7 – Divestiture for additional information. (c) Liquidity and Going Concern Since inception, the Company has incurred recurring losses and negative cash flows from operations. The Company incurred net losses of $9.6 million and $23.5 million, during the thirteen-weeks ended March 31, 2024 and April 2, 2023, respectively, and had an accumulated deficit of $364.5 million and current debt of $65.2 million as of March 31, 2024. The Company had cash and cash equivalents of $1.8 million as of March 31, 2024. The Company believes that its operating losses and negative operating cash flows will continue into the foreseeable future. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to obtain additional funding and restructure its current debt. Historically, the Company’s activities have been financed through private placements of equity securities, debt and proceeds from the Merger. If the Company is not able to secure adequate additional funding when needed, the Company will need to reevaluate its operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs or cease operations entirely. These actions could materially impact the Company’s business, results of operations and future prospects. While the Company has been able to raise multiple rounds of financing, there can be no assurance that in the event the Company requires additional financing, such financing will be available on terms that are favorable, or at all. Failure to generate sufficient cash flows from operations, raise additional capital or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives. Therefore, there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business. They do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern.

Summary of Significant Accounti

	Mar. 31, 2024
Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies (a) Basis of Presentation The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the Unites States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. (b) Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, as well as related disclosure of contingent assets and liabilities. Significant estimates and assumptions made by management include, but are not limited to, the determination of: ● The allocation of the transaction price to identified performance obligations; ● Fair value of warrant liabilities; ● The reserve methodology for inventory obsolescence; ● The reserve methodology for product warranty; ● The reserve methodology for the allowance for credit losses; ● The fair value of the forward purchase agreements; and ● The measurement of stock-based compensation. To the extent that there are material differences between these estimates and actual results, the Company’s financial condition or operating results will be affected. The Company bases its estimates on past experience and other assumptions that the Company believes are reasonable under the circumstances, and the Company evaluates these estimates on an ongoing basis. The Company has assessed the impact and management is not aware of any specific events or circumstances that required an update to the Company’s estimates and assumptions or materially affected the carrying value of the Company’s assets or liabilities as of the date of issuance of this report. These estimates may change as new events occur and additional information is obtained. (c) Segment Information The Company conducts its business in one operating segment that provides custom solar solutions through a standardized platform to its residential solar providers and companies to facilitate the sale and installation of solar energy systems under a single product group. The Company’s Chief Executive Officer (“CEO”) is the Chief Operating Decision Maker (“CODM”). The CODM allocates resources and makes operating decisions based on financial information presented on a consolidated basis. The profitability of the Company’s product group is not a determining factor in allocating resources and the CODM does not evaluate profitability below the level of the consolidated Company. All the Company’s long-lived assets are maintained in the United States of America. (d) Concentration of Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are on deposit with major financial institutions. Such deposits may be in excess of insured limits from time to time. The Company believes that the financial institutions that hold the Company’s cash are financially sound, and accordingly, minimum credit risk exists with respect to these balances. The Company has not experienced any losses due to institutional failure or bankruptcy. The Company performs credit evaluations of its customers and generally does not require collateral for sales on credit. The Company reviews accounts receivable balances to determine if any receivables will potentially be uncollectible and includes any amounts that are determined to be uncollectible in the allowance for credit losses. As of March 31, 2024, two customers had an outstanding balance that represented 36% and 19% of the total accounts receivable balance. As of December 31, 2023, two customers had an outstanding balance that represented 38% and 16% of the total accounts receivable balance. Concentration of customers For the thirteen-weeks ended March 31, 2024, one customer represented 76% of gross revenues. For the thirteen-weeks ended and April 2, 2023, three customers represented 29%, 23% and 12% of gross revenues. Concentration of suppliers For the thirteen-weeks ended March 31, 2024, one supplier represented 99% of the Company’s inventory purchases. For the thirteen-weeks ended April 2, 2023, two suppliers represented 78% and 10% of the Company’s inventory purchases. (e) Cash and Cash Equivalents The Company considers all highly liquid securities that mature within three months or less from the original date of purchase to be cash equivalents. The Company maintains the majority of its cash balances with commercial banks in interest bearing accounts. Cash and cash equivalents include cash held in checking and savings accounts and money market accounts consisting of highly liquid securities with original maturity dates of three months or less from the original date of purchase. (f) Restricted Cash The Company classifies all cash for which usage is limited by contractual provisions as restricted cash. The restricted cash balance was $3.8 million at each of March 31, 2024 and December 31, 2023. Restricted cash consists of deposits in money market accounts, which is used as cash collateral backing letters of credit related to customs duty authorities’ requirements. The Company has presented these balances under restricted cash, as a long-term asset, in its unaudited condensed consolidated balance sheets. The Company reconciles cash, cash equivalents, and restricted cash reported in the unaudited condensed consolidated balance sheets that aggregate to the beginning and ending balances shown in the unaudited condensed consolidated statements of cash flows as follows (in thousands): March 31, December 31, Cash and cash equivalents $ 1,786 $ 2,593 Restricted cash 3,829 3,823 Total cash, cash equivalents and restricted cash $ 5,615 $ 6,416 (g) Revenue Recognition Disaggregation of revenue Refer to the table below for the Company’s revenue recognized by product and service type (in thousands): Thirteen-weeks Ended March 31, April 2, 2024 2023 Solar energy system installations $ 9,922 $ 15,843 Software enhanced services 118 834 Total revenue $ 10,040 $ 16,677 All of the Company’s revenue recognized by geography based on the location of the customer for the thirteen-week periods ended March 31, 2024 and April 2, 2023 was in the United States. Remaining performance obligations The Company has elected the practical expedient not to disclose remaining performance obligations for contracts that are less than one year in length. As of March 31, 2024, the Company has deferred $1.1 million associated with a long-term service contract. As of December 31, 2023, the Company has deferred $1.2 million associated with a long-term service contract, which will be recognized evenly through 2028. Incremental costs of obtaining customer contracts Incremental costs of obtaining customer contracts consist of sales commissions, which are costs paid to third-party vendors who source residential customer contracts for the sale of solar energy systems by the Company. The Company defers sales commissions and recognizes expense in accordance with the timing of the related revenue recognition. Amortization of deferred commissions is recorded as sales commissions in the accompanying unaudited condensed consolidated statements of operations and comprehensive loss. As of March 31, 2024 and December 31, 2023, deferred commissions were $5.1 million and $4.2 million, respectively, which were included in prepaid expenses and other current assets in the accompanying unaudited condensed consolidated balance sheets. Deferred revenue The Company typically invoices its customers upon completion of set milestones, generally upon installation of the solar energy system with the remaining balance invoiced upon passing final building inspection. Standard payment terms to customers range from 30 to 60 days. When the Company receives consideration, or when such consideration is unconditionally due, from a customer prior to delivering goods or services to the customer under the terms of a customer agreement, the Company records deferred revenue. As installation projects are typically completed within 12-months, the Company’s deferred revenue is reflected in current liabilities in the accompanying unaudited condensed consolidated balance sheets. The amount of revenue recognized during the thirteen-week periods ended March 31, 2024 and April 2, 2023 that was included in deferred revenue at the beginning of each period was $1.3 million and $1.9 million, respectively. (h) Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. Financial assets and liabilities held by the Company measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023 include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, the warrant liabilities, SAFE Agreements and FPA liabilities. The carrying amounts of cash, accounts receivable, accounts payable and accrued expenses approximate their fair value because of their short-term nature (classified as Level 1). The warrant liabilities and FPA liabilities are measured at fair value using Level 3 inputs. The Company records subsequent adjustments to reflect the increase or decrease in estimated fair value at each reporting date within the unaudited condensed consolidated statements of operations and comprehensive income (loss) as a component of other income (expense), net. (i) Direct Offering Costs Direct offering costs represent legal, accounting and other direct costs related to the Mergers, which was consummated in July 2023. In accounting for the Mergers, direct offering costs of approximately $5.7 million were reclassified to additional paid-in capital and netted against the Mergers proceeds received upon close. As of March 31, 2024 and December 31, 2023, the Company had no deferred offering costs included within prepaid expenses and other current assets in its unaudited condensed consolidated balance sheets. (j) Warrant Liabilities The Company accounts for its warrant liabilities in accordance with the guidance in ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity, under which the warrants that do not meet the criteria for equity classification and must be recorded as liabilities. The warrant liabilities are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820, Fair Value Measurement, with any subsequent changes in fair value recognized in other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive income (loss). Refer to Note 3 – Fair Value Measurements and Note 12 – Warrants. (k) Forward Purchase Agreements The Company accounts for its FPAs in accordance with the guidance in ASC 480, Distinguishing Liabilities from Equity, as the agreements embody an obligation to transfer assets to settle a forward contract. The warrant liabilities are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820, Fair Value Measurement, with any subsequent changes in fair value recognized in other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive income (loss). Refer to Note 3 – Fair Value Measurements and Note 5 – Forward Purchase Agreements. (l) Net Loss Per Share The Company computes net loss per share following ASC 260, Earnings Per Share. Basic net loss per share is measured as the income or loss available to common stockholders divided by the weighted average common shares outstanding for the period. Diluted net loss per share presents the dilutive effect on a per-share basis from the potential exercise of options and/or warrants. The potentially dilutive effect of options or warrants are computed using the treasury stock method. Securities that potentially have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the diluted loss per share calculation. (m) Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective adoption. The Company is currently evaluating ASU 2023-07, but expects the impact of the disclosures to be immaterial to the Company’s unaudited condensed consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The objective of ASU 2023-09 is to enhance disclosures related to income taxes, including specific thresholds for inclusion within the tabular disclosure of income tax rate reconciliation and specified information about income taxes paid. ASU 2023-09 is effective for public companies starting in annual periods beginning after December 15, 2024. The Company is currently evaluating ASU 2023-09 but expects the impact of the disclosures to be immaterial to the Company’s unaudited condensed consolidated financial statements.

Reverse Recapitalization [Abstract]
Reverse Recapitalization	(4) Reverse Recapitalization As discussed in Note 1 – Organization, on July 18, 2023, the Company consummated the Mergers pursuant to the Amended and Restated Business Combination Agreement. The Mergers was accounted for as a reverse recapitalization, rather than a business combination, for financial accounting and reporting purposes. Accordingly, Complete Solaria was deemed the accounting acquirer (and legal acquiree) and FACT was treated as the accounting acquiree (and legal acquirer). Complete Solaria was determined to be the accounting acquirer based on an evaluation of the following facts and circumstances: ● Complete Solaria’s pre-combination stockholders have the majority of the voting power in the post- merged company; ● Legacy Complete Solaria’s stockholders have the ability to appoint a majority of the Complete Solaria Board of Directors; ● Legacy Complete Solaria’s management team is considered the management team of the post-merged company; ● Legacy Complete Solaria’s prior operations are comprised of the ongoing operations of the post-merged company; ● Complete Solaria is the larger entity based on historical revenues and business operations; and ● the post-merged company has assumed Complete Solaria’s operating name. Under this method of accounting, the reverse recapitalization was treated as the equivalent of Complete Solaria issuing stock for the net assets of FACT, accompanied by a recapitalization. The net assets of FACT are stated at historical cost, with no goodwill or other intangible assets recorded. The unaudited condensed consolidated assets, liabilities, and results of operations prior to the Mergers are those of Legacy Complete Solaria. All periods prior to the Mergers have been retrospectively adjusted in accordance with the Amended and Restated Business Combination Agreement for the equivalent number of preferred or common shares outstanding immediately after the Mergers to effect the reverse recapitalization. Upon the closing of the Mergers and the PIPE Financing in July 2023, the Company received net cash proceeds of $19.7 million less non-cash net liabilities assumed from FACT of $10.1 million. Immediately upon closing of the Mergers, the Company had 45,290,553 shares issued and outstanding of Class A Common Stock. The following table presents the number of shares of Complete Solaria Common Stock outstanding immediately following the consummation of the Mergers: Recapitalization FACT Class A Ordinary Shares, outstanding prior to Mergers 34,500,000 FACT Class B Ordinary Shares, outstanding prior to Mergers 8,625,000 Bonus shares issued to sponsor 193,976 Bonus shares issued to PIPE investors 120,000 Bonus shares issued to FPA investors 150,000 Shares issued from PIPE financing 1,690,000 Shares issued from FPA agreements, net of recycled shares 5,558,488 Less: redemption of FACT Class A Ordinary Shares (31,041,243 ) Total shares from the Mergers and PIPE Financing 19,796,221 Legacy Complete Solaria shares 20,034,257 2022 Convertible Note Shares 5,460,075 Shares of Complete Solaria Common stock immediately after Mergers 45,290,553 In connection with the Mergers, the Company incurred direct and incremental costs of approximately $15.8 million related to legal, accounting, and other professional fees, which were offset against the Company’s additional paid-in capital. Of the $15.8 million, $5.2 million was incurred by Legacy Complete Solaria and $10.6 million was incurred by FACT. The Company did not make any cash payments to settle transaction costs in the thirteen-weeks ended March 31, 2024. As of December 31, 2023, the Company made cash payments totaling $5.4 million to settle transaction costs. As a result of the Closing, outstanding 2022 Convertible Notes were converted into shares of Complete Solaria Common Stock.

Forward Purchase Agreements [Abstract]
Forward Purchase Agreements	(5) Forward Purchase Agreements In July 2023, FACT and Legacy Complete Solaria, Inc. entered into FPAs with each of (i) Meteora; (ii) Polar, and (iii) Sandia (each individually, a “Seller”, and together, the “FPA Sellers”). Pursuant to the terms of the FPAs, the FPA Sellers may (i) purchase through a broker in the open market, from holders of Shares other than the Company or affiliates thereof, FACT’s ordinary shares, par value of $0.0001 per share, (the “Shares”). While the FPA Sellers have no obligation to purchase any Shares under the FPAs, the aggregate total Shares that may be purchased under the FPAs shall be no more than 6,720,000 in aggregate. The FPA Sellers may not beneficially own greater than 9.9% of issued and outstanding Shares following the Mergers as per the Amended and Restated Business Combination Agreement. The key terms of the forward contracts are as follows: ● The FPA Sellers can terminate the transaction following the Optional Early Termination (“OET”) Date which shall specify the quantity by which the number of shares is to be reduced (such quantity, the “Terminated Shares”). Seller shall terminate the transaction in respect of any shares sold on or prior to the maturity date. The counterparty is entitled to an amount from the Seller equal to the number of terminated shares multiplied by a reset price. The reset price is initially $10.56 (the “Initial Price”) and is subject to a $5.00 floor. ● The FPA contains multiple settlement outcomes. Per the terms of the agreements, the FPAs will (1) settle in cash in the event the Company is due cash upon settlement from the FPA Sellers or (2) settle in either cash or shares, at the discretion of the Company, should the settlement amount adjustment exceed the settlement amount. Should the Company elect to settle via shares, the equity will be issued in Complete Solaria Common Stock, with a per share price based on the volume-weighted average price (“VWAP”) Price over 15 scheduled trading days. The magnitude of the settlement is based on the Settlement Amount, an amount equal to the product of: (1) Number of shares issued to the FPA Seller pursuant to the FPA, less the number of Terminated Shares multiplied by (2) the VWAP Price over the valuation period. The Settlement amount will be reduced by the Settlement Adjustment, an amount equal to the product of (1) Number of shares in the Pricing Date Notice, less the number of Terminated Shares multiplied by $2.00. ● The Settlement occurs as of the Valuation Date, which is the earlier to occur of (a) the date that is two years after the date of the Closing Date of the Mergers (b) the date specified by Seller in a written notice to be delivered to the Counterparty at the Seller’s discretion (which Valuation Date shall not be earlier than the day such notice is effective) after the occurrence of certain triggering events; and (c) 90 days after delivery by the Counterparty of a written notice in the event that for any 20 trading days during a 30 consecutive trading day-period (the “Measurement Period”) that occurs at least 6 months after the Closing Date, the VWAP Price is less than the then applicable Reset Price. The Company entered into four separate FPAs, three of which, associated with the obligation to issue 6,300,000 Shares, were entered into prior to the closing of the Mergers. Upon signing the FPAs, the Company incurred an obligation to issue a fixed number of shares to the FPA Sellers contingent upon the closing of the Mergers in addition to the terms and conditions associated with the settlement of the FPAs. The Company accounted for the contingent obligation to issue shares in accordance with ASC 815, Derivatives and Hedging Additionally, in accordance with ASC 480, Distinguishing Liabilities from Equity Through the date of issuance of the Complete Solaria Common Stock in satisfaction of the Company’s obligation to issue shares around the closing of the Mergers, the Company recorded $35.5 million to other income (expense), net associated with the issuance of 6,720,000 shares of Complete Solaria Common Stock in association with the FPAs. As of the closing of the Mergers and issuance of the Complete Solaria Common Stock underlying the FPAs, the fair value of the prepaid FPAs was an asset balance of $0.1 million and was recorded on the Company’s unaudited condensed consolidated balance sheets and within other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive loss. Subsequently, the change of fair value of the forward purchase liabilities amounted to an expense of $5.6 million for the thirteen-weeks ended March 31, 2024. As of March 31, 2024, and December 31, 2023, the forward purchase liabilities amounted to $9.4 million and $3.8 million, respectively. Of the balances as of March 31, 2024 and December 31, 2023, $7.9 million and $3.2 million, respectively, are due to related parties Refer to Note 19 – Related Party Transactions for further details. On December 18, 2023, the Company and the FPA Sellers entered into separate amendments to the FPAs (the “Amendments”). The Amendments lower the reset floor price of each FPA from $5.00 to $3.00 and allow the Company to raise up to $10.0 million of equity from existing stockholders without triggering certain anti-dilution provisions contained in the FPAs; provided, the insiders pay a price per share for their initial investment equal to the closing price per share as quoted on the Nasdaq on the day of purchase; provided, further, that any subsequent investments are made at a price per share equal to the greater of (a) the closing price per share as quoted by Nasdaq on the day of the purchase or (b) the amount paid in connection with the initial investment.

The warrant contained two tranches, the first of which is immediately exercisable for 1,995,879 shares. The second tranche, which was determined to be a separate unit of account, expired on December 31, 2022 prior to becoming exercisable. In December 2023, Carlyle was issued an additional warrant to purchase an additional 2,190,604 shares of the Company’s common stock related to an anti-dilution provision within the CS Solis Debt that provides for such additional warrants under such circumstances as provided within the CS Solis Debt. At issuance, the relative fair value of the warrant was determined to be $3.4 million using the Black-Scholes model with the following weighted average assumptions: expected term of 7 years; expected volatility of 73.0%; risk-free interest rate of 1.9%; and no In July 2023, and in connection with the closing of the Mergers, the Carlyle debt and warrants were modified. Based on the exchange ratio included in the Mergers, the 1,995,879 outstanding warrants to purchase Legacy Complete Solaria Common Stock prior to modification were exchanged into warrants to purchase 1,995,879 shares of Complete Solaria Common Stock. As part of the modification, the warrant, which expires on July 18, 2030, provides Carlyle with the right to purchase shares of Complete Solaria Common Stock based on (a) the greater of (i) 1,995,879 shares and (ii) the number of shares equal to 2.795% of Complete Solaria’s issued and outstanding shares of common stock, on a fully-diluted basis; plus (b) on and after the date that is ten (10) days after the date of the agreement, an additional 350,000 shares; plus (c) on and after the date that is thirty (30) days after the date of the agreement, if the original investment amount has not been repaid, an additional 150,000 shares; plus (d) on and after the date that is ninety (90) days after the date of the agreement, if the original investment amount has not been repaid, an additional 250,000 shares, in each case, of Complete Solaria Common Stock at a price of $0.01 per share. Of the additional warrants that become exercisable after the modification, the tranches of 350,000 warrants vesting ten days after the date of the agreement and 150,000 warrants vesting thirty days after the date of the agreement are exercisable as of December 31, 2023. The modification of the warrant resulted in the reclassification of previously equity-classified warrants to liability classification, which was accounted for in accordance with ASC 815 and ASC 718, Compensation – Stock Compensation no Series D-7 Warrants (Converted to common stock warrants “Replacement Warrants”) In November 2022, the Company issued warrants to purchase 656,630 shares of Series D-7 preferred stock (the “Series D-7 warrants”) in conjunction with the Business Combination. The warrant contains two tranches. The first tranche of 518,752 shares of Series D-7 preferred stock is exercisable at an exercise price of $2.50 per share upon consummation of a merger transaction, or at an exercise price of $2.04 per share upon remaining private and has an expiration date of April 2024. The second tranche of 137,878 shares of Series D-7 preferred stock is exercisable at an exercise price of $5.00 per share upon consummation of a merger transaction, or at an exercise price of $4.09 per share upon remaining private and has an expiration date of April 2024. The fair value of the Series D-7 warrants was $7.8 million as of December 31, 2022 and $2.4 million as of July 18, 2023 when the warrants were reclassified from redeemable convertible preferred stock warrant liability to additional paid-in capital, as the exercise price of the warrants is fixed at $2.50 per share of Complete Solaria Common Stock for the first tranche and $5.00 per share of Complete Solaria Common Stock for the second tranche upon the closing of the Mergers. In October 2023, the Company entered into an Assignment and Acceptance Agreement (“Assignment Agreement”), (Refer to Note 13 – Borrowings and SAFE Agreements). In connection with the Assignment Agreement, the Company also entered into the First Amendment to Warrant to Purchase Stock Agreements with the holders of the Series D-7 warrants. Pursuant to the terms of the agreement, the warrants to purchase 1,376,414 shares of Series D-7 preferred stock converted into warrants to purchase 656,630 shares of common stock, the Replacement Warrants. As a result of the warrant amendment, the Company reclassified the Replacement Warrants from equity to liability. The Replacement Warrants were remeasured to their fair value on the amendment effective date, and the Company has recorded subsequent changes in fair value in other income (expense), net on its unaudited condensed consolidated statements of operations and comprehensive loss. The Replacement Warrants remain outstanding as of March 31, 2024. Public, Private Placement, and Working Capital Warrants In conjunction with the Mergers, Complete Solaria, as accounting acquirer, was deemed to assume 6,266,667 warrants to purchase FACT Class A Ordinary Shares that were held by the sponsor at an exercise price of $11.50 (“Private Placement Warrants”) and 8,625,000 warrants to purchase FACT’s shareholders FACT Class A Ordinary Shares at an exercise price of $11.50 (“Public Warrants”). Subsequent to the Mergers, the Private Placement Warrants and Public Warrants are exercisable for shares of Complete Solaria Common Stock and meet liability classification requirements since the warrants may be required to be settled in cash under a tender offer. In addition, the Private Placement Warrants are potentially subject to a different settlement amount as a result of being held by the Sponsor which precludes the Private Placement Warrants from being considered indexed to the entity’s own stock. Therefore, these warrants are classified as liabilities on the Company’s unaudited condensed consolidated balance sheets. The Company determined the Public and Private warrants to be classified as a liability and fair valued the warrants on the issuance date using the publicly available price for the warrants of $6.7 million. The fair value of these warrants was $0.8 million as of March 31, 2024, and the Company recorded the change in fair value of $0.5 million in other income (expense), net in the unaudited condensed consolidated statements of operations and comprehensive loss for the thirteen-weeks ended March 31, 2024. Additionally, at the closing of the Mergers, the Company issued 716,668 Working Capital warrants, which have identical terms as the Private Placement Warrants to the sponsor in satisfaction of certain liabilities of FACT. The warrants were fair valued at $0.3 million upon the closing of the Mergers, which was recorded in warrant liability on the unaudited condensed consolidated balance sheets. As of March 31, 2024, the Working Capital warrants had a fair value of $0.03 million, and the Company recorded the change in fair value of $0.02 million as other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive loss. Equity Classified Warrants Series B Warrants (Converted to Common Stock Warrants) In February 2016, the Company issued a warrant to purchase 5,054 shares of Series B preferred stock (the “Series B warrant”) in connection with a 2016 credit facility. The Series B warrant is immediately exercisable at an exercise price of $4.30 per share and has an expiration date of February 2026. The relative fair value of the Series B warrant at issuance was recorded as a debt issuance cost within other non-current liabilities upon issuance. The fair value of the Series B warrant was less than $0.1 million as of December 31, 2022 and as of July 18, 2023, when the Series B warrant was reclassified from warrant liability to additional paid-in capital, upon the warrant becoming exercisable into shares of Complete Solaria Common Stock upon the close of the Mergers. Prior to its reclassification from equity to a liability during 2023, the changes in fair value were recorded in other income (expense), net on the accompanying unaudited condensed consolidated statements of operations and comprehensive loss for the thirteen-weeks ended April 2, 2023. Series C Warrants (Converted to Common Stock Warrants) In July 2016, the Company issued a warrant to purchase 148,477 shares of Series C preferred stock (the “Series C warrant”) in connection with the Series C financing. The Series C warrant agreement also provided for an additional number of Series C shares calculated on a monthly basis commencing on June 2016 based on the principal balance outstanding of the notes payable outstanding. The maximum number of shares exercisable under the Series C warrant agreement is 482,969 shares of Series C preferred stock. The Series C warrant was immediately exercisable at an exercise price of $1.00 per share and has an expiration date of July 2026. The relative fair value of the Series C warrant at issuance was recorded as Series C preferred stock issuance costs and redeemable convertible preferred stock warrant liability and changes in the fair value of the warrant were recorded in other income (expense), net on the accompanying unaudited condensed consolidated statements of operations and comprehensive loss for the thirteen-weeks ended April 2, 2023. The fair value of the Series C warrant was $2.3 million as of July 18, 2023, when the Series B warrant was reclassified from redeemable convertible preferred stock warrant liability to additional paid-in capital, upon the warrant becoming exercisable into shares of Complete Solaria Common Stock. Series C-1 Warrants (Converted to Common Stock Warrants) In January 2020, the Company issued a warrant to purchase 173,067 shares of common stock in conjunction with the Series C-1 preferred stock financing. The warrant is immediately exercisable at an exercise price of $0.01 per share and has an expiration date of January 2030. The warrant remains outstanding as of March 31, 2024. At issuance, the relative fair value of the warrant was determined to be $0.1 million using the Black-Scholes model with the following weighted average assumptions: expected term of 10 years; expected volatility of 62.5%; risk-free interest rate of 1.5%; and no SVB Common Stock Warrants In May and August 2021, the Company issued warrants to purchase 2,473 and 2,525 shares of common stock, respectively, in conjunction with the Fifth and Sixth Amendments to the Loan and Security Agreement (“Loan Agreement”) with Silicon Valley Bank (“SVB”). The warrants are immediately exercisable at exercise prices of $0.38 and $0.62 per share, respectively, and have expiration dates in 2033. The warrants remain outstanding as of March 31, 2024. At issuance, the relative fair value of the warrants was determined to be less than $0.1 million in aggregate using the Black-Scholes model with the following weighted average assumptions: expected term of 12 years; expected volatility of 73.0%; risk-free interest rate of 1.7% and 1.3% for the May and August 2021 warrants, respectively; and no Promissory Note Common Stock Warrants In October 2021, the Company issued a warrant to purchase 24,148 shares of common stock in conjunction with the issuance of a short-term promissory note. The warrant is immediately exercisable at an exercise price of $0.01 per share and has an expiration date of October 2031. The warrant remains outstanding as of March 31, 2024. At issuance, the relative fair value of the warrant was determined to be less than $0.1 million using the Black-Scholes model with the following weighted average assumptions: expected term of 10 years; expected volatility of 73.0%; risk-free interest rate of 1.5%; and no November 2022 Common Stock Warrants In November 2022, the Company issued a warrant to a third-party service provider to purchase 78,962 shares of common stock in conjunction with the Business Combination. The warrant was immediately exercisable at an exercise price of $8.00 per share and had an expiration date of April 2024. In May 2023, the Company amended the warrant, modifying (i) the shares of common stock to be purchased to 31,680, (ii) the exercise price to $0.01, and (iii) the expiration date to the earlier of October 2026 or the closing of an IPO. The impact of the modification was not material to the unaudited condensed consolidated financial statements. At issuance and upon the modification, the relative fair value of the warrant was determined to be $0.1 million using the Black-Scholes model with the following weighted average assumptions: expected term of 1.5 years; expected volatility of 78.5%; risk-free interest rate of 4.7%; and no July 2023 Common Stock Warrants In July 2023, the Company issued a warrant to a third-party service provider to purchase 38,981 shares of the Company’s common stock in exchange for services provided in obtaining financing at the Closing of the Mergers. The warrant is immediately exercisable at a price of $0.01 per share and has an expiration date of July 2028. At issuance, the fair value of the warrant was determined to be $0.2 million, based on the intrinsic value of the warrant and the $0.01 per share exercise price. As the warrant is accounted for as an equity issuance cost, the warrant is recorded within additional paid-in capital on the unaudited condensed consolidated balance sheets. The warrant is not remeasured in future periods as it meets the conditions for equity classification. Warrant Consideration In July 2023, in connection with the Mergers, the Company issued 6,266,572 warrants to purchase Complete Solaria Common Stock to holders of Legacy Complete Solaria Redeemable Convertible Preferred Stock, Legacy Complete Solaria Common Stock. The exercise price of the common stock warrants is $11.50 per share and the warrants expire 10 years from the date of the Mergers. The warrant consideration was issued as part of the close of the Mergers and was recorded within additional paid-in capital, net of the issuance costs of the Mergers. As of March 31, 2024, all warrants issued as warrant consideration remain outstanding.

Borrowings and SAFE Agreements [Abstract]
Borrowings and SAFE Agreements	(13) Borrowings and SAFE Agreements The Company’s borrowings consisted of the following (in thousands): As of March 31, December 31, 2024 2023 2018 Bridge Notes $ 11,376 $ 11,031 Revolver Loan 5,290 5,168 Secured Credit Facility 12,699 12,158 Polar Settlement Agreement — 300 Total Notes payable 29,365 28,657 Debt in CS Solis 35,840 33,280 Total notes payable and convertible notes, net 65,205 61,937 Less current portion (65,205 ) (61,937 ) Notes payable and convertible notes, net of current portion $ — $ — Notes Payable 2018 Bridge Notes In December 2018, Solaria Corporation issued senior subordinated convertible secured notes (“2018 Notes”) totaling approximately $3.4 million in exchange for cash. The notes bear interest at the rate of 8% per annum and the investors are entitled to receive twice the face value of the 2018 Notes at maturity. The 2018 Notes are secured by substantially all of the assets of Solaria Corporation. In 2021, the 2018 Notes were amended extending the maturity date to December 13, 2022. In connection with the 2021 amendment, Solaria had issued warrants to purchase shares of Series E-1 redeemable convertible preferred stock of Solaria. The warrants were exercisable immediately in whole or in part at and expire on December 13, 2031. As part of the Business Combination with Complete Solar, all the outstanding warrants issued to the lenders were assumed by the parent company, Complete Solaria. The 2018 Notes are secured by substantially all of the assets of Complete Solaria. In December 2022, the Company entered into an amendment to the 2018 Bridge Notes extending the maturity date from December 13, 2022 to December 13, 2023, and the 2018 Notes remain outstanding as of March 31, 2024. In connection with the amendment, the 2018 Notes will continue to bear interest at 8% per annum and are entitled to an increased repayment premium from 110% to 120% of the principal and accrued interest at the time of repayment. The Company concluded that the amendment represented a troubled debt restructuring as the Company was experiencing financial difficulty, and the amended terms resulted in a concession to the Company. As the future undiscounted cash payments under the modified terms exceeded the carrying amount of the 2018 Notes on the date of modification, the modification was accounted for prospectively. The incremental repayment premium is being amortized to interest expense using the effective interest rate method. As of March 31, 2024 and December 31, 2023, the carrying value of the 2018 Notes was $11.4 million and $11.0 million, respectively. Interest expense recognized for the thirteen-week periods ended March 31, 2024 and April 2, 2023 was $0.3 million and $0.3 million, respectively. As of March 31, 2024, the carrying value of the 2018 Notes approximates their fair value. Revolver Loan In October 2020, Solaria entered into a loan agreement (“SCI Loan Agreement”) with Structural Capital Investments III, LP (“SCI”). The SCI Loan Agreement is comprised of two facilities, a term loan (the “Term Loan”) and a revolving loan (the “Revolving Loan”) (together “Original Agreement”) for $5.0 million each with a maturity date of October 31, 2023. Both the Term Loan and the Revolving Loan were fully drawn upon closing. The Term Loan was repaid prior to the acquisition of Solaria by Complete Solar and was not included in the Business Combination. The Revolving Loan has a term of thirty-six months, with the principal due at the end of the term and an annual interest rate of 7.75% or Prime rate plus 4.5%, whichever is higher. The SCI Loan Agreement requires the Company to meet certain financial covenants relating to the maintenance of specified restricted cash balance, achieve specified revenue targets and maintain specified contribution margins (“Financial Covenants”) over the term of the Revolving Loan. The Revolving Loan is collateralized by substantially all assets and property of the Company. In the years ended December 31, 2022 and December 31, 2021, Solaria entered into several Amended and Restated Loan and Security Agreements with SCI to forbear SCI from exercising any rights and remedies available to it as a result of the Company not meeting certain Financial Covenants required by the Original Agreement. As a result of these amendments changes were made to the Financial Covenants, and Solaria recorded a total of $1.9 million in amendment fees which amount was recorded in Other Liabilities, and this liability was included in the assumed liabilities for purchase price accounting. Solaria had historically issued warrants to purchase shares of Series E-1 redeemable convertible preferred stock of Solaria (“SCI Series E-1 warrants”). The warrants were fully exercisable in whole or in part at any time during the term of the Original agreement. As part of the Business Combination with Complete Solar, all the outstanding SCI Series E-1 warrants were assumed by the parent company, Complete Solaria. The Revolving Loan outstanding on the date of the Business Combination was fair valued at $5.0 million for the purpose of purchase price accounting. The Revolving Loan principal balance at March 31, 2024 and December 31, 2023 amounted to $5.3 million and $5.1 million, respectively. Interest expense recognized for the thirteen-week periods ended March 31, 2024 and April 2, 2023 was $0.1 million and $0.1 million, respectively. The Company was in compliance with all the Financial Covenants as of March 31, 2024. In October 2023, the Company entered into an Assignment Agreement whereby Structural Capital Investments III, LP assigned the SCI debt to Kline Hill Partners Fund LP, Kline Hill Partners IV SPV LLC, Kline Hill Partners Opportunity IV SPV LLC, (collectively “Kline Hill”) and Rodgers Massey Revocable Living Trust for a total purchase price of $5.0 million. The Company has identified this arrangement as a related party transaction, as discussed in Note 18 – Related Party Transactions. The SCI Revolving Loan continued to remain outstanding as of March 31, 2024 and is currently being renegotiated. On May 1, 2024, the Company entered into an agreement with Kline Hill that will cancel this obligation upon satisfaction of certain events. Refer to Note 19 - Subsequent Events for further details. Secured Credit Facility In December 2022, the Company entered into a secured credit facility agreement with Kline Hill Partners IV SPV LLC and Kline Hill Partners Opportunity IV SPV LLC (“Secured Credit Facility”). The Secured Credit Facility agreement allows the Company to borrow up to 70% of the net amount of its eligible vendor purchase orders with a maximum amount of $10.0 million at any point in time. The purchase orders are backed by relevant customer sales orders which serves as collateral. The amounts drawn under the Secured Credit Facility may be reborrowed provided that the aggregate borrowing does not exceed $20.0 million. The repayment under the Secured Credit Facility is the borrowed amount multiplied by 1.15x if repaid within 75 days and borrowed amount multiplied by 1.175x if repaid after 75 days. The Company may prepay any borrowed amount without premium or penalty. Under the original terms, the Secured Credit Facility agreement was due to mature in April 2023. The Company is in the process of amending the Secured Credit Facility agreement to extend its maturity date. At March 31, 2024, the balance outstanding was $12.7 million, including accrued financing cost of $5.0 million, and as of December 31, 2023, the balance outstanding was $12.2 million, including accrued financing cost of $4.5 million. The Company recognized interest expense of $0.5 million and $1.7 million related to the Secured Credit Facility during the thirteen-weeks ended March 31, 2024 and April 2, 2023, respectively. As of March 31, 2024, the total estimated fair value of the Secured Credit Facility approximated its carrying value. On May 1, 2024, the Company entered into an agreement with Kline Hill that will cancel this obligation upon satisfaction of certain events. Refer to Note 19 - Subsequent Events for further details. Polar Settlement Agreement In September 2023, in connection with the Mergers, the Company entered into a settlement and release agreement with Polar Multi-Strategy Master Fund (“Polar”) for the settlement of a working capital loan that had been made by Polar to the Sponsor, prior to the closing of the Mergers. The settlement agreement required the Company to pay Polar $0.5 million in ten equal monthly installments and did not accrue interest. As of December 31, 2023, the balance owed to Polar was $0.3 million all of which was paid in the period ended March 31, 2024. Debt in CS Solis As part of the Reorganization described in Note 1(a) Organization - Description of Business and Note 12 - Warrants, the Company received cash and recorded debt for an investment by Carlyle. The investment was made pursuant to a subscription agreement, under which Carlyle contributed $25.6 million in exchange for 100 Class B Membership Units of CS Solis and the Company contributed the net assets of Complete Solar, Inc. in exchange for 100 Class A Membership Units. The Class B Membership Units are mandatorily redeemable by the Company on the three-year anniversary of the effective date of the CS Solis amended and restated LLC agreement (February 14, 2025). The Class B Membership Units accrue interest that is payable upon redemption at a rate of 10.5% (which is structured as a dividend payable based on 25% of the investment amount measured quarterly), compounded annually, and subject to increases in the event the Company declares any dividends. In connection with the investment by Carlyle, the Company issued Carlyle a warrant to purchase 5,978,960 shares of the Company’s common stock at a price of $0.01 per share, of which, the purchase of 4,132,513 shares of the Company’s common stock is immediately exercisable. The Company has accounted for the mandatorily redeemable investment from Carlyle in accordance with ASC 480, Distinguishing Liabilities from Equity, and has recorded the investment as a liability, which was accreted to its redemption value under the effective interest method. The Company has recorded the warrants as a discount to the liability. Refer to Note 11 – Common Stock, for further discussion of the warrants issued in connection with the Class B Membership Units. On July 17 and July 18, 2023, and in connection with obtaining consent for the Mergers, Legacy Complete Solaria, FACT and Carlyle entered into an Amended and Restated Consent to the Business Combination Agreement (“Carlyle Debt Modification Agreement”) and an amended and restated warrant agreement (“Carlyle Warrant Amendment”), which modified the terms of the mandatorily redeemable investment made by Carlyle in Legacy Complete Solaria. The Carlyle Debt Modification Agreement accelerates the redemption date of the investment, which was previously February 14, 2025 and is now March 31, 2024 subsequent to the modification. The acceleration of the redemption date of the investment, resulted in the total redemption amount to be 1.3 times the principal at December 31, 2023. The redemption amount will increase to 1.4 times the original investment at March 31, 2024. Additionally, as part of the amendment, the parties entered into an amended and restated warrant agreement. As part of the Carlyle Warrant Amendment, Complete Solaria issued Carlyle a warrant to purchase up to 2,745,879 shares of Complete Solaria Common Stock at a price per share of $0.01, which is inclusive of the outstanding warrant to purchase 1,995,879 shares at the time of modification. The warrant, which expires on July 18, 2030, provides Carlyle with the right to purchase shares of Complete Solaria Common Stock based on (a) the greater of (i) 1,995,879 shares and (ii) the number of shares equal to 2.795% of Complete Solaria’s issued and outstanding shares of common stock, on a fully-diluted basis; plus (b) on and after the date that is ten (10) days after the date of the agreement, an additional 350,000 shares; plus (c) on and after the date that is thirty (30) days after the date of the agreement, if the original investment amount has not been repaid, an additional 150,000 shares; plus (d) on and after the date that is ninety (90) days after the date of the agreement, if the original investment amount has not been repaid, an additional 250,000 shares, in each case, of Complete Solaria Common Stock at a price of $0.01 per share. The warrants are classified as liabilities under ASC 815 and are recorded within warrant liability on the Company’s unaudited condensed consolidated statements of operations and comprehensive loss. The Company accounted for the modification of the debt due with CS Solis as a debt extinguishment in accordance with ASC 480 and ASC 470. As a result of the extinguishment, the Company recorded a loss on extinguishment, of $10.3 million in the thirteen-week period ended October 1, 2023. As of the modification date, the Company recorded the fair value of the new debt of $28.4 million as short-term debt with CS Solis. As of March 31, 2024, the debt has a redemption obligation of $35.8 million under the Carlyle Debt Modification Agreement. The debt in CS Solis is currently under negotiation. The Company has recorded a liability of $35.8 million and $33.3 million included in short-term debt with CS Solis on its unaudited condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023, respectively. For the thirteen-week periods ended March 31, 2024 and April 2, 2023, the Company has recorded accretion of the liability as interest expense of $2.5 million and $0.8 million, respectively, and made no payments of interest expense. For the thirteen-week periods ended March 31, 2024 and April 2, 2023 the Company recorded amortization of issuance costs as interest expense of zero and $0.3 million, respectively. As of March 31, 2024, the total estimated fair value of the Company’s debt with CS Solis was $35.8 million, which was estimated based on Level 3 inputs. SAFE Agreements First SAFE On January 31, 2024, the Company entered into a simple agreement for future equity (the “First SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (the “Purchaser”), a related party, in connection with the Purchaser investing $1.5 million in the Company. The First SAFE does not accrued interest. The First SAFE was initially convertible into shares of the Company’s common stock, par value $0.0001 per share, upon the initial closing of a bona fide transaction or series of transactions with the principal purpose of raising capital, pursuant to which the Company would have issued and sold shares of its common stock at a fixed valuation (an “Equity Financing”), at a per share conversion price which was equal to the lower of (i)(a) $53.54 million divided by (b) the Company’s capitalization immediately prior to such Equity Financing (such conversion price, the “SAFE Price”), and (ii) 80% of the price per share of its common stock sold in the Equity Financing. If the Company consummated a change of control prior to the termination of the First SAFE, the Purchaser would have been automatically entitled to receive a portion of the proceeds of such liquidity event equal to the greater of (i) $1.5 million and (ii) the amount payable on the number of shares of common stock equal to (a) $1.5 million divided by (b)(1) $53.54 million divided by (2) the Company’s capitalization immediately prior to such liquidity event (the “Liquidity Price”), subject to certain adjustments as set forth in the First SAFE. The First SAFE was convertible into a maximum of 1,431,297 shares of the Company’s common stock, assuming a per share conversion price of $1.05, which is the product of (i) $1.31, the closing price per share of the Company’s common stock on January 31, 2024, multiplied by (ii) 80%. On April 21, 2024, the Company entered into an amendment of the First SAFE which resulted in the First SAFE into shares of the Company’s common stock. Refer to Note 19 – Subsequent Events for further details. Second SAFE On February 15, 2024, the Company entered into a simple agreement for future equity (the “Second SAFE” and together with the First SAFE, the “SAFEs”) with the Purchaser, a related party, in connection with the Purchaser investing $3.5 million in the Company. The First SAFE does not accrued interest. The Second SAFE was initially convertible into shares of the Company’s common stock upon the initial closing of an Equity Financing at a per share conversion price which was equal to the lower of (i) the SAFE Price, and (ii) 80% of the price per share of Common Stock sold in the Equity Financing. If the Company consummated a change of control prior to the termination of the Second SAFE, the Purchaser would have been automatically entitled to receive an amount equal to the greater of (i) $3.5 million and (ii) the amount payable on the number of shares of Common Stock equal to $3.5 million divided by the Liquidity Price, subject to certain adjustments as set forth in the Second SAFE. The Second SAFE was convertible into a maximum of 3,707,627 shares of the Company’s common stock, assuming a per share conversion price of $0.94, which is the product of (i) $1.18, the closing per share price of its common stock on February 15, 2024, multiplied by (ii) 80%. On April 21, 2024, the Company entered into an amendment of the Second SAFE which resulted in the conversion of the Second SAFE into shares of the Company’s common stock. Refer to Note 19 – Subsequent Events for further details.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	(14) Stock-Based Compensation In July 2023, the Company’s board of directors adopted and stockholders approved the 2023 Incentive Equity Plan (the “2023 Plan”). The 2023 Plan became effective immediately upon the closing of the Amended and Restated Business Combination Agreement. Initially, a maximum number of 8,763,322 shares of Complete Solaria common stock may be issued under the 2023 Plan. In addition, the number of shares of Complete Solaria common stock reserved for issuance under the 2023 Plan will automatically increase on January 1 of each year, starting on January 1, 2024 and ending on January 1, 2033, in an amount equal to the lesser of (1) 4% of the total number of shares of Complete Solaria’s common stock outstanding on December 31 of the preceding year, or (2) a lesser number of shares of Complete Solaria Common Stock determined by Complete Solaria’s board of directors prior to the date of the increase. The maximum number of shares of Complete Solaria common stock that may be issued on the exercise of incentive stock options (“ISOs”) under the 2023 Plan is three times the number of shares available for issuance upon the 2023 Plan becoming effective (or 26,289,966 shares). Historically, awards were granted under the Amended and Restated Complete Solaria Omnibus Incentive Plan (“2022 Plan”), the Complete Solar 2011 Stock Plan (“2011 Plan”), the Solaria Corporation 2016 Stock Plan (“2016 Plan”) and the Solaria Corporation 2006 Stock Plan (“2006 Plan”) (together with the Complete Solaria, Inc. 2023 Incentive Equity Plan (“2023 Plan”), “the Plans”). The 2022 Plan is the successor of the Complete Solar 2021 Stock Plan, which was amended and assumed in connection with the acquisition of Solaria. The 2011 Plan is the Complete Solar 2011 Stock Plan that was assumed by Complete Solaria in the Required Transaction. The 2016 Plan and the 2006 Plan are the Solaria stock plans that were assumed by Complete Solaria in the Required Transaction.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	(16) Commitments and Contingencies Warranty Provision The Company typically provides a 10-year warranty on its solar energy system installations, which provides assurance over the workmanship in performing the installation, including roof leaks caused by the Company’s performance. For solar panel sales, the Company provides a 30-year warranty that the products will be free from defects in material and workmanship. The Company will retain its warranty obligation associated with its panel sales, subsequent to the disposal of its panel business. The Company accrues warranty costs when revenue is recognized for solar energy systems sales and panel sales, based primarily on the volume of new sales that contain warranties, historical experience with and projections of warranty claims, and estimated solar energy system and panel replacement costs. The Company records a provision for estimated warranty expenses in cost of revenues within the accompanying unaudited condensed consolidated statements of operations and comprehensive loss. Warranty costs primarily consist of replacement materials and equipment and labor costs for service personnel. Activity by period relating to the Company’s warranty provision was as follows (in thousands): Thirteen- Year Ended Warranty provision, beginning of period $ 4,849 $ 3,981 Accruals for new warranties issued 265 2,968 Settlements (250 ) (2,100 ) Warranty provision, end of period $ 4,864 $ 4,849 Warranty provision, current $ 1,448 $ 1,433 Warranty provision, noncurrent $ 3,416 $ 3,416 Indemnification Agreements From time to time, in its normal course of business, the Company may indemnify other parties, with which it enters into contractual relationships, including customers, lessors, and parties to other transactions with the Company. The Company may agree to hold other parties harmless against specific losses, such as those that could arise from breach of representation, covenant or third-party infringement claims. It may not be possible to determine the maximum potential amount of liability under such indemnification agreements due to the unique facts and circumstances that are likely to be involved in each particular claim and indemnification provision. Historically, there have been no such indemnification claims. In the opinion of management, any liabilities resulting from these agreements will not have a material adverse effect on the business, financial position, results of operations, or cash flows. Legal Matters The Company is a party to various legal proceedings and claims which arise in the ordinary course of business. The Company records a liability when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. If the Company determines that a loss is reasonably possible and the loss or range of loss can be reasonably estimated, the Company discloses the reasonably possible loss. The Company adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Legal costs are expensed as incurred. Although claims are inherently unpredictable, the Company is not aware of any matters that may have a material adverse effect on its business, financial position, results of operations, or cash flows. The Company has recorded zero SolarPark Litigation In January 2023, SolarPark Korea Co., LTD (“SolarPark”) demanded approximately $80.0 million during discussions between the Company and SolarPark. In February 2023, the Company submitted its statement of claim seeking approximately $26.4 million in damages against SolarPark. The ultimate outcome of this arbitration is currently unknown and could result in a material liability to the Company. However, the Company believes that the allegations lack merit and intends to vigorously defend all claims asserted. No liability has been recorded in the Company’s unaudited condensed consolidated financial statements as the likelihood of a loss is not probable at this time. On March 16, 2023, SolarPark filed a complaint against Solaria and the Company in the U.S. District Court for the Northern District of California (“the court”). The complaint alleges a civil conspiracy involving misappropriation of trade secrets, defamation, tortious interference with contractual relations, inducement to breach of contract, and violation of California’s Unfair Competition Law. The complaint indicates that SolarPark has suffered in excess of $220.0 million in damages. On May 11, 2023, SolarPark filed a motion for preliminary injunction to seek an order restraining the Company from using or disclosing SolarPark’s trade secrets, making or selling shingled modules other than those produced by SolarPark, and from soliciting solar module manufacturers to produce shingled modules using Solaria’s shingled patents. On May 18, 2023, the Company responded by filing a motion for partial dismissal and stay. On June 1, 2023, SolarPark filed an opposition to the Company’s motion for dismissal and stay and a reply in support of their motion for preliminary injunction. On June 8, 2023, the Company replied in support of its motion for partial dismissal and stay. On July 11, 2023, the court conducted a hearing to consider SolarPark and the Company’s respective motions. On August 3, 2023, the court issued a ruling, which granted the preliminary injunction motion with respect to any purported misappropriation of SolarPark’s trade secrets. The court’s ruling does not prohibit the Company from producing shingled modules or from utilizing its own patents for the manufacture of shingled modules. The court denied SolarPark’s motion seeking a defamation injunction. The court denied the Company’s motion to dismiss and granted the Company’s motion to stay the entire litigation pending the arbitration in Singapore. On September 1, 2023, the Company filed a Limited Notice of Appeal to appeal the August 2023 order granting SolarPark’s motion for preliminary injunction. On September 26, 2023, the Company filed a Notice of Withdrawal of Appeal and will not appeal the Court’s Preliminary Injunction Order. No liability has been recorded in the Company’s unaudited condensed consolidated financial statements as the likelihood of a loss is not probable at this time. Siemens Litigation On July 22, 2021, Siemens filed a lawsuit in which Siemens alleged that the Company breached express and implied warranties under a purchase order that Siemens placed with the Company for a solar module system. Siemens claimed damages of approximately $6.9 million, inclusive of amounts of the Company’s indemnity obligations to Siemens, plus legal fees. On February 22, 2024, the Court issued an order against the Company which awarded Siemens approximately $6.9 million, inclusive of the Company’s indemnity obligations to Siemens, plus legal fees, the amount of which will be determined at a later hearing. On March 15, 2024, Siemens filed a motion seeking to recover $2.67 million for attorneys’ fees, expenses, and pre-judgment interest. The Court will conduct a hearing on Siemens’ motion in late May 2024. Pending entry of a final judgment by the Court, the Company intends to appeal such judgment. The Company has recorded $6.9 million as a legal loss related to this litigation, excluding the $2.67 million for attorneys’ fees, expenses, and pre-judgment interest, in accrued expenses and other current liabilities on its unaudited condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023. China Bridge Litigation On August 24 2023, China Bridge Capital Limited (“China Bridge”) alleged breach of contract and demanded $6.0 million. The complaint names FACT as the defendant. The complaint alleges China Bridge and FACT entered into a financial advisory agreement in October 2022 whereby FACT engaged China Bridge to advise and assist FACT in identifying a company for FACT to acquire. As part of the agreement, China Bridge claims that FACT agreed to pay China Bridge a $6.0 million advisory fee if FACT completed such an acquisition. China Bridge claims it introduced Complete Solaria to FACT and is therefore owed the $6.0 million advisory fee. The Company believes that the allegations lack merit and intends to vigorously defend all claims asserted. No liability has been recorded in the Company’s unaudited condensed consolidated financial statements as the likelihood of a loss is not probable at this time. Letters of Credit The Company had $3.5 million of outstanding letters of credit related to normal business transactions as of March 31, 2024. These agreements require the Company to maintain specified amounts of cash as collateral in segregated accounts to support the letters of credit issued thereunder. As discussed in Note 2 – Summary of Significant Accounting Policies, the cash collateral in these restricted cash accounts was $3.8 million and $3.8 million as of March 31, 2024 and December 31, 2023, respectively.

Basic and Diluted Net Loss Per Share [Abstract]
Basic and Diluted Net Loss Per Share	(17) Basic and Diluted Net Loss Per Share The Company uses the two-class method to calculate net loss per share. No The unaudited basic and diluted shares and net loss per share for the thirteen-week period ended April 2, 2023 has been retroactively restated to give effect to the conversion of shares of legal acquiree’s convertible instruments into shares of legal acquiree common stock as though the conversion had occurred as of the beginning of the period. The retroactive restatement is consistent with the presentation on the accompanying unaudited condensed consolidated statements of stockholders’ deficit. The following table sets forth the computation of the Company’s basic and diluted net loss per share attributable to common stockholders for the thirteen-week periods ended March 31, 2024 and April 2, 2023 (in thousands, except share and per share amounts): Thirteen- Thirteen- Weeks Numerator: Net loss from continuing operations $ (9,588 ) $ (15,709 ) Net loss from discontinued operations –– (7,805 ) Net loss $ (9,588 ) $ (23,514 ) Denominator: Weighted average common shares outstanding, basic and diluted 49,077,330 25,200,347 Net loss per share: Continuing operations – basic and diluted $ (0.20 ) $ (0.62 ) Discontinued operations – basic and diluted $ –– $ (0.31 ) Net loss per share – basic and diluted $ (0.20 ) $ (0.93 ) The computation of basic and diluted net loss per share attributable to common stockholders is the same for the thirteen-week periods ended March 31, 2024 and April 2, 2023 because the inclusion of potential shares of common stock would have been anti-dilutive for the periods presented. The following table presents the potential common shares outstanding that were excluded from the computation of diluted net loss per share of common stock as of the periods presented because including them would have been anti-dilutive: As of March 31, April 2, Common stock warrants 23,024,556 89,313 Preferred stock warrants — 2,386,879 Stock options and RSUs issued and outstanding 11,436,369 9,714,894 Potential common shares excluded from diluted net loss per share 34,460,924 12,191,086

Related Party Transactions [Abstract]
Related Party Transactions	(18) Related Party Transactions From October 2022 through June 2023, the Company issued convertible promissory notes (“2022 Convertible Notes”) of approximately $33.3 million to various investors, out of which $12.1 million was issued to five related parties. Additionally, the Company acquired a related party convertible note, on the same terms as the 2022 Convertible Notes as part of the acquisition of Solaria, with a fair value of $6.7 million at the time of the acquisition. The related party debt is presented as convertible notes, net, due to related parties, noncurrent in the accompanying unaudited condensed consolidated balance sheets. The principal amount of the outstanding balance on the 2022 Convertible Notes accrues at 5.0%, compounded annually. For the thirteen-week periods ended March 31, 2024 and April 2, 2023, the Company has recognized zero and $0.4 million, respectively, in interest expense related to the related party 2022 Convertible Notes. In June 2023, the Company received $3.5 million of prefunded PIPE proceeds from a related party investor in conjunction with the Company’s merger with Freedom Acquisition I Corp. In July 2023, in connection with the Mergers, in addition to the $3.5 million of related party PIPE proceeds noted above, the Company received additional PIPE proceeds from related parties of $12.1 million. In July 2023, in connection with the Mergers, the Company issued 120,000 shares to a related party as a transaction bonus. Refer to Note 1(a) – Description of Business and Note 4 – Reverse Recapitalization for further discussion.

In connection with the FPAs, the Company recognized other expense of $30.7 million for the fiscal year ended December 31, 2023 in connection with the issuance of 5,670,000 shares of Complete Solaria Common Stock to the related party FPA Sellers. The Company also recognized other income of $0.3 million in connection with the issuance of the FPAs with related parties. As of March 31, 2024, the Company has recognized a liability associated with the FPAs of $7.9 million due to related parties in its unaudited condensed consolidated balance sheets, and the Company has recognized other expense associated with the change in fair value of the FPA liability due to related parties of $4.7 million in its unaudited condensed consolidated statements of operations and comprehensive loss for the thirteen-weeks ended March 31, 2024. In September 2023, in connection with the Mergers, the Company entered into a settlement and release agreement with a related party for the settlement of a working capital loan made to the Sponsor, prior to the closing of the Mergers. As part of the settlement agreement, the Company agreed to pay the related party $0.5 million as a return of capital, which is paid in ten equal monthly installments and does not accrue interest. The Company paid $0.2 million in 2023 and the remaining balance of $0.3 million was paid in the thirteen-week period ended March 31, 2024. The SAFEs, as described in Note 13 – Borrowing Arrangements, entered into in January 2024 and February 2024 were with the Rodgers Massey Freedom and Free Markets Charitable Trust, a related party. The Company received proceeds from the SAFEs totaling $5.0 million in exchange for debt that was subsequently converted into shares of the Company’s common stock as discussed in Note 19 – Subsequent Events. There were no other material related party transactions during the thirteen-week periods ended March 31, 2024 and April 2, 2023.

Subsequent Events [Abstract]
Subsequent Events	(19) Subsequent Events Notice of Delisting or Failure to Satisfy a Continued Listing Rule; Minimum Bid Price Requirement On April 16, 2024, the Company received written notice (the “Notice”) from the Nasdaq Stock Market, LLC (“Nasdaq”) notifying the Company that it is not in compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5450(a)(1) for continued listing on The Nasdaq Global Market. Nasdaq Listing Rule 5450(a)(1) requires listed securities to maintain a minimum bid price of $1.00 per share, and Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. The Notice does not impact the listing of the Company’s common stock on The Nasdaq Global Market at this time. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has 180 calendar days to regain compliance with the minimum bid price requirement. To regain compliance, the closing bid price of the Company’s common stock must be at least $1.00 per share for a minimum of ten consecutive business days before October 14, 2024. In the event that the Company does not regain compliance within this 180-day period, the Company may be eligible to seek an additional compliance period of 180 calendar days if it meets the continued listing requirement for the market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and provides written notice to Nasdaq of its intent to cure the deficiency during this second compliance period by effecting a reverse stock split if necessary. However, if it appears to the Nasdaq staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq will provide notice to the Company that its common stock will be subject to delisting. The Company intends to actively monitor the closing bid price of its common stock and will evaluate available options to regain compliance with the minimum bid price requirement. Notice of Delisting or Failure to Satisfy a Continued Listing Rule; Minimum Market Value of Listed Securities On April 16, 2024, the Company received a letter (the “Letter”) from the staff at Nasdaq notifying the Company that, for the 30 consecutive trading days prior to the date of the Letter, the Company’s common stock had traded at a value below the minimum $50,000,000 “Market Value of Listed Securities” (“MVLS”) requirement set forth in Nasdaq Listing Rule 5450(b)(2)(A), which is required for continued listing of the Company’s common stock on The Nasdaq Global Market. The Letter is only a notification of deficiency, not of imminent delisting, and has no current effect on the listing or trading of the Company’s securities on Nasdaq. In accordance with Nasdaq listing rule 5810(c)(3)(C), the Company has 180 calendar days, or until October 14, 2024, to regain compliance. The Letter notes that to regain compliance, the Company’s common stock must trade at or above a level such that the Company’s MVLS closes at or above $50,000,000 for a minimum of ten consecutive business days during the compliance period, which ends October 14, 2024. The Letter further notes that if the Company is unable to satisfy the MVLS requirement prior to such date, the Company may be eligible to transfer the listing of its securities to The Nasdaq Capital Market (provided that the Company then satisfies the requirements for continued listing on that market). If the Company does not regain compliance by October 14, 2024, Nasdaq staff will provide written notice to the Company that its securities are subject to delisting. At that time, the Company may appeal any such delisting determination to a hearings panel. The Company intends to actively monitor the Company’s MVLS between now and October 14, 2024, and may, if appropriate, evaluate available options to resolve the deficiency and regain compliance with the MVLS requirement. While the Company is exercising diligent efforts to maintain the listing of its securities on Nasdaq, there can be no assurance that the Company will be able to regain or maintain compliance with Nasdaq listing standards. Amendment to SAFEs Agreements As described in Note 13 – Borrowings and SAFE Agreements, the Company’s SAFEs were convertible into shares of the Company’s common stock upon the initial closing of an Equity Financing. On April 21, 2024, the Company entered into an amendment for each of its First SAFE and Second SAFE to convert the invested amounts into shares of the Company’s common stock. The conversion share price was $0.36, calculated as the product of (i) $0.45, the closing price of the Common Stock on April 19, 2024, multiplied by (ii) 80%. The First SAFE and Second SAFE converted into 4,166,667 and 9,722,222 shares of the Company’s common stock, respectively. Entry into a Definitive Agreement to Cancel Debt in Exchange for Equity and Other Consideration On May 1, 2024, the Company entered into a common stock purchase agreement (the “Common Stock Purchase Agreement”) with Kline Hill providing for (a) the cancellation of all indebtedness owed to Kline Hill by the Company, termination of all debt instruments by and between the Company and Kline Hill, and the satisfaction of all obligations owed to Kline Hill by the Company under the terminated debt instruments, (b) the issuance of 9,800,000 shares of the Company’s common stock to Kline Hill, (c) the issuance of warrants (the “Kline Hill Warrants” and the shares issuable therefrom, the “Warrant Shares”) to Kline Hill to purchase up to 3,700,000 shares of the Company’s common stock, with an exercise price per share of $0.62 (the closing price per share of the Company’s common stock as reported on the Nasdaq Capital Market of the date of the Agreement), and (d) a one-time $3,750,000 cash payment to Kline Hill upon the earlier of (i) the Company achieving $100,000,000 of trailing twelve month revenue, or (ii) the Company achieving $10,000,000 of trailing twelve month EBITDA. The Kline Hill Warrants will be sold to Kline Hill at a price of $0.125 per Warrant Share. The closing of the foregoing transactions will occur when the following conditions are met: Carlyle executes an agreement to cancel all debt owed to Carlyle by the Company, and all debt owed to Carlyle and its affiliates by the Company is no longer outstanding. On May 15, 2024, the Company announced that Carlyle has agreed to release the Company from its debt obligations in return for a third-party cash payment. Upon the completion of the above transactions the Company’s debt outstanding as March 31, 2024 of $65.2 million will have been replaced with 9,800,000 newly issued shares of the Company’s common stock and $10.0 million in debt from a new lender. Amendments to Forward Purchase Agreements On May 7 and 8, 2024, respectively, the Company entered into separate amendments to the Forward Purchase Agreements (the collectively the “Second Amendments”) with Sandia (the “Sandia Second Amendment”) and Polar (the “Polar Second Amendment”). The Second Amendments lower the reset price of each Forward Purchase Agreement from $3.00 to $1.00 per share and amend the VWAP Trigger Event provision to read as “After December 31, 2024, an event that occurs if the VWAP Price, for any 20 trading days during a 30 consecutive trading day-period, is below $1.00 per Share.”. The Sandia Second Amendment is not effective until the Company executes similar amendments with both Polar and Meteora.

Significant Accounting Policies [Abstract]
Basis of Presentation	(a) Basis of Presentation The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the Unites States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	(b) Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, as well as related disclosure of contingent assets and liabilities. Significant estimates and assumptions made by management include, but are not limited to, the determination of: ● The allocation of the transaction price to identified performance obligations; ● Fair value of warrant liabilities; ● The reserve methodology for inventory obsolescence; ● The reserve methodology for product warranty; ● The reserve methodology for the allowance for credit losses; ● The fair value of the forward purchase agreements; and ● The measurement of stock-based compensation. To the extent that there are material differences between these estimates and actual results, the Company’s financial condition or operating results will be affected. The Company bases its estimates on past experience and other assumptions that the Company believes are reasonable under the circumstances, and the Company evaluates these estimates on an ongoing basis. The Company has assessed the impact and management is not aware of any specific events or circumstances that required an update to the Company’s estimates and assumptions or materially affected the carrying value of the Company’s assets or liabilities as of the date of issuance of this report. These estimates may change as new events occur and additional information is obtained.
Segment Information	(c) Segment Information The Company conducts its business in one operating segment that provides custom solar solutions through a standardized platform to its residential solar providers and companies to facilitate the sale and installation of solar energy systems under a single product group. The Company’s Chief Executive Officer (“CEO”) is the Chief Operating Decision Maker (“CODM”). The CODM allocates resources and makes operating decisions based on financial information presented on a consolidated basis. The profitability of the Company’s product group is not a determining factor in allocating resources and the CODM does not evaluate profitability below the level of the consolidated Company. All the Company’s long-lived assets are maintained in the United States of America.
Concentration of Risks	(d) Concentration of Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are on deposit with major financial institutions. Such deposits may be in excess of insured limits from time to time. The Company believes that the financial institutions that hold the Company’s cash are financially sound, and accordingly, minimum credit risk exists with respect to these balances. The Company has not experienced any losses due to institutional failure or bankruptcy. The Company performs credit evaluations of its customers and generally does not require collateral for sales on credit. The Company reviews accounts receivable balances to determine if any receivables will potentially be uncollectible and includes any amounts that are determined to be uncollectible in the allowance for credit losses. As of March 31, 2024, two customers had an outstanding balance that represented 36% and 19% of the total accounts receivable balance. As of December 31, 2023, two customers had an outstanding balance that represented 38% and 16% of the total accounts receivable balance. Concentration of customers For the thirteen-weeks ended March 31, 2024, one customer represented 76% of gross revenues. For the thirteen-weeks ended and April 2, 2023, three customers represented 29%, 23% and 12% of gross revenues. Concentration of suppliers For the thirteen-weeks ended March 31, 2024, one supplier represented 99% of the Company’s inventory purchases. For the thirteen-weeks ended April 2, 2023, two suppliers represented 78% and 10% of the Company’s inventory purchases.
Cash and Cash Equivalents	(e) Cash and Cash Equivalents The Company considers all highly liquid securities that mature within three months or less from the original date of purchase to be cash equivalents. The Company maintains the majority of its cash balances with commercial banks in interest bearing accounts. Cash and cash equivalents include cash held in checking and savings accounts and money market accounts consisting of highly liquid securities with original maturity dates of three months or less from the original date of purchase.
Restricted Cash	(f) Restricted Cash The Company classifies all cash for which usage is limited by contractual provisions as restricted cash. The restricted cash balance was $3.8 million at each of March 31, 2024 and December 31, 2023. Restricted cash consists of deposits in money market accounts, which is used as cash collateral backing letters of credit related to customs duty authorities’ requirements. The Company has presented these balances under restricted cash, as a long-term asset, in its unaudited condensed consolidated balance sheets. The Company reconciles cash, cash equivalents, and restricted cash reported in the unaudited condensed consolidated balance sheets that aggregate to the beginning and ending balances shown in the unaudited condensed consolidated statements of cash flows as follows (in thousands): March 31, December 31, Cash and cash equivalents $ 1,786 $ 2,593 Restricted cash 3,829 3,823 Total cash, cash equivalents and restricted cash $ 5,615 $ 6,416
Revenue Recognition	(g) Revenue Recognition Disaggregation of revenue Refer to the table below for the Company’s revenue recognized by product and service type (in thousands): Thirteen-weeks Ended March 31, April 2, 2024 2023 Solar energy system installations $ 9,922 $ 15,843 Software enhanced services 118 834 Total revenue $ 10,040 $ 16,677 All of the Company’s revenue recognized by geography based on the location of the customer for the thirteen-week periods ended March 31, 2024 and April 2, 2023 was in the United States. Remaining performance obligations The Company has elected the practical expedient not to disclose remaining performance obligations for contracts that are less than one year in length. As of March 31, 2024, the Company has deferred $1.1 million associated with a long-term service contract. As of December 31, 2023, the Company has deferred $1.2 million associated with a long-term service contract, which will be recognized evenly through 2028. Incremental costs of obtaining customer contracts Incremental costs of obtaining customer contracts consist of sales commissions, which are costs paid to third-party vendors who source residential customer contracts for the sale of solar energy systems by the Company. The Company defers sales commissions and recognizes expense in accordance with the timing of the related revenue recognition. Amortization of deferred commissions is recorded as sales commissions in the accompanying unaudited condensed consolidated statements of operations and comprehensive loss. As of March 31, 2024 and December 31, 2023, deferred commissions were $5.1 million and $4.2 million, respectively, which were included in prepaid expenses and other current assets in the accompanying unaudited condensed consolidated balance sheets. Deferred revenue The Company typically invoices its customers upon completion of set milestones, generally upon installation of the solar energy system with the remaining balance invoiced upon passing final building inspection. Standard payment terms to customers range from 30 to 60 days. When the Company receives consideration, or when such consideration is unconditionally due, from a customer prior to delivering goods or services to the customer under the terms of a customer agreement, the Company records deferred revenue. As installation projects are typically completed within 12-months, the Company’s deferred revenue is reflected in current liabilities in the accompanying unaudited condensed consolidated balance sheets. The amount of revenue recognized during the thirteen-week periods ended March 31, 2024 and April 2, 2023 that was included in deferred revenue at the beginning of each period was $1.3 million and $1.9 million, respectively.
Fair Value Measurements	(h) Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: ● Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. ● Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. ● Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. Financial assets and liabilities held by the Company measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023 include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, the warrant liabilities, SAFE Agreements and FPA liabilities. The carrying amounts of cash, accounts receivable, accounts payable and accrued expenses approximate their fair value because of their short-term nature (classified as Level 1). The warrant liabilities and FPA liabilities are measured at fair value using Level 3 inputs. The Company records subsequent adjustments to reflect the increase or decrease in estimated fair value at each reporting date within the unaudited condensed consolidated statements of operations and comprehensive income (loss) as a component of other income (expense), net.
Direct Offering Costs	(i) Direct Offering Costs Direct offering costs represent legal, accounting and other direct costs related to the Mergers, which was consummated in July 2023. In accounting for the Mergers, direct offering costs of approximately $5.7 million were reclassified to additional paid-in capital and netted against the Mergers proceeds received upon close. As of March 31, 2024 and December 31, 2023, the Company had no deferred offering costs included within prepaid expenses and other current assets in its unaudited condensed consolidated balance sheets.
Warrant Liabilities	(j) Warrant Liabilities The Company accounts for its warrant liabilities in accordance with the guidance in ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity, under which the warrants that do not meet the criteria for equity classification and must be recorded as liabilities. The warrant liabilities are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820, Fair Value Measurement, with any subsequent changes in fair value recognized in other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive income (loss). Refer to Note 3 – Fair Value Measurements and Note 12 – Warrants.
Forward Purchase Agreements	(k) Forward Purchase Agreements The Company accounts for its FPAs in accordance with the guidance in ASC 480, Distinguishing Liabilities from Equity, as the agreements embody an obligation to transfer assets to settle a forward contract. The warrant liabilities are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820, Fair Value Measurement, with any subsequent changes in fair value recognized in other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive income (loss). Refer to Note 3 – Fair Value Measurements and Note 5 – Forward Purchase Agreements.
Net Loss Per Share	(l) Net Loss Per Share The Company computes net loss per share following ASC 260, Earnings Per Share. Basic net loss per share is measured as the income or loss available to common stockholders divided by the weighted average common shares outstanding for the period. Diluted net loss per share presents the dilutive effect on a per-share basis from the potential exercise of options and/or warrants. The potentially dilutive effect of options or warrants are computed using the treasury stock method. Securities that potentially have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the diluted loss per share calculation.
Accounting Pronouncements Not Yet Adopted	(m) Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective adoption. The Company is currently evaluating ASU 2023-07, but expects the impact of the disclosures to be immaterial to the Company’s unaudited condensed consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The objective of ASU 2023-09 is to enhance disclosures related to income taxes, including specific thresholds for inclusion within the tabular disclosure of income tax rate reconciliation and specified information about income taxes paid. ASU 2023-09 is effective for public companies starting in annual periods beginning after December 15, 2024. The Company is currently evaluating ASU 2023-09 but expects the impact of the disclosures to be immaterial to the Company’s unaudited condensed consolidated financial statements.

Investment description

The Carlyle Debt Modification Agreement accelerates the redemption date of the investment, which was previously February 14, 2025 and is now March 31, 2024 subsequent to the modification. The acceleration of the redemption date of the investment, resulted in the total redemption amount to be 1.3 times the principal at December 31, 2023. The redemption amount will increase to 1.4 times the original investment at March 31, 2024. Additionally, as part of the amendment, the parties entered into an amended and restated warrant agreement. As part of the Carlyle Warrant Amendment, Complete Solaria issued Carlyle a warrant to purchase up to 2,745,879 shares of Complete Solaria Common Stock at a price per share of $0.01, which is inclusive of the outstanding warrant to purchase 1,995,879 shares at the time of modification. The warrant, which expires on July 18, 2030, provides Carlyle with the right to purchase shares of Complete Solaria Common Stock based on (a) the greater of (i) 1,995,879 shares and (ii) the number of shares equal to 2.795% of Complete Solaria’s issued and outstanding shares of common stock, on a fully-diluted basis; plus (b) on and after the date that is ten (10) days after the date of the agreement, an additional 350,000 shares; plus (c) on and after the date that is thirty (30) days after the date of the agreement, if the original investment amount has not been repaid, an additional 150,000 shares; plus (d) on and after the date that is ninety (90) days after the date of the agreement, if the original investment amount has not been repaid, an additional 250,000 shares, in each case, of Complete Solaria Common Stock at a price of $0.01 per share. The warrants are classified as liabilities under ASC 815 and are recorded within warrant liability on the Company’s unaudited condensed consolidated statements of operations and comprehensive loss.
