SUNPOWER INC. AND SUBSIDIARIES
Notes to Unaudited Condensed Consolidated Financial Statements
(1) Organization
(a) Description of business
SunPower Inc. and Subsidiaries (“SunPower” or the “Company”) is the rebranded name of Complete Solaria, Inc. (“Complete Solaria”). The rebranding was effective April 22, 2025. References to the Company and SunPower include the same entity under its previous name of Complete Solaria.
The Company originally incorporated in Delaware under the name Complete Solaria, Inc. and is a residential solar installer that offers storage and home energy solutions to customers in North America. The Company was formed through Complete Solar Holding Corporation’s acquisition of The Solaria Corporation (“Solaria”). The Company is headquartered in Orem, Utah.
Complete
Solar, Inc. (“Complete Solar”) was incorporated in Delaware on
On July 18, 2023, the Company consummated a series of merger transactions contemplated by an Amended and Restated Business Combination Agreement entered into with wholly-owned subsidiaries of Freedom Acquisition I Corp. (“FACT”) (“Mergers”), equating to a reverse recapitalization for accounting purposes. Under the reverse recapitalization of accounting, FACT was treated as the acquired company for financial statement reporting purposes. This determination was based on the Company having a majority of the voting power of the post-combination company, the Company’s senior management comprising substantially all of the senior management of the post-combination company, and the Company’s operations comprising the ongoing operations of the post-combination company. Accordingly, for accounting purposes, the Mergers were treated as the equivalent of a capital transaction in which Complete Solaria issued stock for the net assets of FACT. The net assets of FACT were stated at historical cost, with no goodwill or other intangible assets recorded.
On August 5, 2024, Complete Solaria entered into an Asset Purchase Agreement (the “APA”) among Complete Solaria, SunPower Corporation and SunPower Corporation’s direct and indirect subsidiaries (collectively, the “SunPower Debtors”) providing for the Company’s purchase of certain assets relating to the Blue Raven Solar business, New Homes Business and Non-Installing Dealer network previously operated by the SunPower Debtors (“SunPower Acquisition”). The APA was entered into in connection with a voluntary petition filed by SunPower Corporation under Chapter 11 of the United States Code, 11 U.S.C.§§ 101-1532. The SunPower Acquisition was approved on September 23, 2024, by the United States Bankruptcy Court for the District of Delaware. The Company completed the acquisition in the Company’s fiscal fourth quarter on September 30, 2024.
On September 21, 2025, Complete Solaria, Inc., and Complete Solar, Inc, a subsidiary of the Company, entered into a Membership Interest Purchase Agreement (“MIPA”) with Sunder Energy LLC (“Sunder”) and the seller, Chicken Parm Pizza LLC (“Seller/Member”), the sole member of Sunder. The acquisition of Sunder was completed on September 24, 2025, and the financial results of Sunder have been included in the Company’s unaudited condensed consolidated financial statements since the date of acquisition. Refer to Note 3 – Business Combinations for a description of Sunder.
The aforementioned acquisitions were accounted for as business combinations in accordance with ASC 805, Business Combinations as more fully described in Note 3 – Business Combinations.
The Company completed its legal renaming to SunPower Inc. in the period ended September 28, 2025.

(b) Liquidity and going concern
Since inception through September 28, 2025, the
Company has incurred recurring losses and negative cash flows from operations. The Company’s loss from continuing operations was
$
Management is actively pursuing plans to mitigate these conditions, including obtaining additional capital resources through equity or debt financing and leveraging support from significant shareholders when necessary. Historically, the Company has raised funds through private placements of equity securities, issuance of convertible notes and debt, and proceeds from mergers. During the year, funding from significant shareholders, has supported working capital requirements, and similar measures may be considered in the upcoming periods.
Management plans to proactively position the Company to access capital markets once eligible and pursue strategic opportunities to strengthen liquidity. Given the one-year eligibility requirement for Form S-3 after regaining current filer status, the Company will focus on alternative financing options to maintain flexibility and efficiency in capital raising.
However, there can be no assurance that these plans will be successful or that financing will be available on favorable terms. If adequate funding cannot be secured, the Company may need to reevaluate its operating plan, which could include reducing expenditure, extending payment terms with suppliers, liquidating assets, or suspending certain programs.
Therefore, there is substantial doubt about the Company’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.
(2) Summary of Significant Accounting Policies
(a) Basis of presentation
The interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
The accompanying interim condensed consolidated financial statements are unaudited and have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim unaudited condensed consolidated financial statements do not include all the information and disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, these interim unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s financial position as of September 28, 2025, and the results of operations for the thirteen and thirty-nine week periods ended September 28, 2025 and September 29, 2024. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year or any other future period. These interim unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended December 29, 2024, included in the Company’s Annual Report on Form 10-K filed with the SEC on April 30, 2025.
The Company’s operates on a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. The Company’s fiscal year for 2024 ended December 29, 2024. The Company’s third fiscal quarters for 2025 and 2024 in this report on Form 10-Q ended on September 28, 2025 (“Third Quarter 2025”) and September 29, 2024 (“Third Quarter 2024”), respectively.

(b) Cash and cash equivalents and restricted cash
The Company reconciles cash, cash equivalents, and restricted cash reported in its unaudited condensed consolidated balance sheets that aggregate to the beginning and ending balances shown in the Company’s unaudited condensed consolidated statements of cash flows as follows (in thousands):
| As of | ||||||||
| September 28, 2025 | December 29, 2024 | |||||||
| Cash and cash equivalents | $ | $ | ||||||
| Restricted cash | ||||||||
| Total cash, cash equivalents and restricted cash | $ | $ | ||||||
(c) Estimated credit losses
The Company recognizes an allowance for credit losses at the time a receivable is recorded based on the Company’s estimate of expected credit losses, historical write-off experience, and current account knowledge, and adjusts this estimate over the life of the receivable as needed. The Company evaluates the aggregation and risk characteristics of a receivable pool and develops loss rates that reflect historical collections over the time horizon that the Company is exposed to credit risk, and payment terms or conditions that may materially affect future forecasts.
The Company performs ongoing credit evaluations of its customers’ financial condition when deemed necessary. The Company maintains an allowance for credit losses based on the expected collectability of all accounts receivable, which takes into consideration an analysis of historical bad debts, specific customer creditworthiness and current economic trends. The Company believes that its concentration of credit risk is limited because of the large number of customers, credit quality of the customer base, small account balances for most of these customers, and customer geographic diversification. The Company does not have any off-balance sheet credit exposure relating to its customers.
The following table summarizes the allowance for credit loss activity as of and for the periods ended (in thousands):

(e) Revenue recognition
Revenue is recognized for Residential Solar Installation and New Homes Business when a customer obtains control of promised products and services and the Company has satisfied its performance obligations which is the date by which substantially all of its design and installation is complete for a fully functioning solar power system to interconnect to the local power grid.
Installation includes the design of a solar energy system, the delivery of the components of the solar energy system (i.e., photovoltaic system, inverter, battery storage, etc.), installation services and services facilitating the connection of the solar energy system to the power grid. The Company accounts for these services as inputs to a combined output, resulting in a single service-based performance obligation.
The amount of revenue recognized reflects the consideration which the Company expects to be entitled to receive in exchange for the products and services. To achieve this core principle, the Company applies the following five steps:
Step 1. Identification of the contract(s) with a customer;
Step 2. Identification of the performance obligations in the contracts(s);
Step 3. Determination of the transaction price;
Step 4. Allocation of the transaction price to the performance obligations;
Step 5. Recognition of the revenue when, or as, the Company satisfies a performance obligation.
Residential Solar Installation revenues
The Company’s Residential Solar Installation segment sells products through a network of installing and non-installing dealers and resellers, as well as its internal sales team. The Company’s contracts with customers include three primary contract types:
| ● | Cash agreements – The Company contracts directly with homeowners who purchase the solar energy system and related services from the Company. Customers are invoiced on a billing schedule, where the majority of the transaction price is due upon installation with an additional payment due when the system passes inspection by the authority having jurisdiction. |
| ● | Financing partner agreements – In its financing partner agreements, the Company contracts directly with homeowners for the purchase of the solar energy system and related services. The Company refers the homeowner to a financing partner to finance the system, and the homeowner makes payments directly to the financing partner. The Company receives consideration from the financing partner on a billing schedule where the majority of the transaction price is due upon installation with an additional payment due when the system passes inspection by the authority having jurisdiction. |
| ● | Power purchase agreements and lease agreements – The Company contracts directly with a leasing partner to perform the solar energy system installation, and the homeowner will finance the system through a power purchase agreement (or lease), which is signed with the Company’s leasing partner. The Company considers the leasing partner to be its customer, as the Company does not contract directly with the homeowner and the leasing partner takes ownership of the system upon the completion of installation. The Company receives consideration from the leasing partner on a billing schedule where the majority of the transaction price is due upon installation with an additional payment due when the system passes inspection by the authority having jurisdiction. |

New Homes Business revenues
The Company’s New Homes Business segment sells through a network of home builders as well as its internal sales team. The Company’s contracts with customers include two primary contract types:
| ● | Cash agreements – The Company contracts directly with homebuilders who purchase the solar energy system from the Company and are the customers in the transaction. The Company’s customers are invoiced upon the completion of installation. |
| ● | Lease agreements – Prior to SunPower Debtor’s declaration of bankruptcy, certain homeowners had intended to lease a system from SunPower Debtors but were unable to consummate the transaction (as a result of SunPower Debtor’s declaration of bankruptcy). The in-process system inventory (installed on recently constructed homes) was acquired by the Company in connection with the SunPower Acquisition. The Company contracted directly with a leasing partner to facilitate the leasing of the system to the impacted homeowners. The Company considers the leasing partner to be its customer. Under the terms of the Company’s arrangement with the leasing partner, control is not transferred to the customer until the completed system is accepted by the customer. The Company receives consideration from the leasing partner following the acceptance of the system. |
The Company’s performance obligation for both of these reportable segments is to design and install a fully functioning solar energy system. For all contract types (with the exception of New Homes Business Lease agreements), the Company recognizes revenue over time. The Company’s over-time revenue recognition begins when the solar power system is fully installed (as it is at this point that control of the asset begins to be transferred to the customer, and the customer retains the significant risks and rewards of ownership of the solar power system). The Company recognizes revenue using the input method based on direct costs to install the system and defers the costs of installation until such time that control of the asset transfers to the customer (installation). For New Homes Business Lease agreements, the Company considers the performance obligation to be satisfied at a point in time upon acceptance of the system by the customer.
Revenue is generally recognized at the transaction price contained within the agreement, net of the costs of financing, or other consideration paid to the customers that is not in exchange for a distinct good or service. The Company’s arrangements may contain clauses that can either increase or decrease the transaction price. Variable consideration is estimated at each measurement date at its most likely amount to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur and true-ups are applied prospectively as such estimates change.
The Company records deferred revenue for amounts invoiced that are received in advance of the provisioning of services. In certain contracts with customers, the Company arranges for a third-party financing partner to provide financing to the customer. The Company collects upfront from the financing partner and the customer will provide instalment payments to the financing partner. The Company records revenue in the amount received from the financing partner, net of any financing fees charged to the homeowner, which the Company considers to be a customer incentive. None of the Company’s contracts contain a significant financing component.
Sunder
The Company earns revenue from contracts sold to customers for solar installations performed by third-party installation companies. The Company recognizes revenue at a point in time when Permission to Operate (“PTO”) is complete. The Company acts as an agent in these arrangements and records revenue on a net basis. The Company does not have significant financing components in its contracts. The Company does not provide warranty services and does not record a warranty reserve.
Costs to obtain and fulfill contracts
The Company’s costs to obtain and fulfill contracts, when recognized, associated with systems sales are expensed as sales commission and cost of revenue, respectively. In addition, incentives the Company provides to its customers, such as discounts and rebates, are recorded net to the revenue the Company has recognized on the solar power system.

Remaining performance obligations
The Company elected the practical expedient not to disclose the remaining performance obligations for contracts that are less than one year in length.
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 expenses 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 September 28, 2025 and December 29, 2024, deferred commissions were not material.

(g) Recent accounting pronouncements
Accounting pronouncements adopted
In July 2025, the FASB issued ASU 2025-05 “Measurement of Credit Losses for Accounts Receivable and Contract Assets” which provides an update to all entities with a practical expedient when estimating expected credit losses. This ASU is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. The Company adopted ASU 2025-05 in the thirteen week period ended September 28, 2025. The impact of the adoption was not material to the condensed consolidated financial statements.

Accounting pronouncements not yet adopted
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 will adopt this ASU in its annual report for the fiscal year ending December 28, 2025. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires the disaggregation of certain expenses in the notes of the financial statements to provide enhanced transparency into the expense captions presented on the face of the income statement. The FASB subsequently issued ASU 2025-01 “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date”, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in ASU 2024-03 in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
In November 2024, the FASB issued ASU No. 2024-04, Debt-Debt with Conversion and Other Options (Subtopic 470-20) (“ASU 2024-04”). The guidance in ASU 2024-04 clarifies the requirements related to accounting for the settlement of a debt instrument as an induced conversion. The standard is effective for fiscal years beginning after December 15, 2025, and interim periods within fiscal years beginning after December 15, 2025, with early adoption permitted as of the beginning of a reporting period if the entity has also adopted ASU 2020-06 for that period. The Company is currently evaluating the impact that the adoption of ASU 2024-04 may have on its consolidated financial statements.
In March 2024, the FASB issued ASU 2024-02 “Codification Improvements-Amendments to Remove References to the Concepts Statements”, which removes various references to concepts statements from the FASB Accounting Standards Codification. This ASU is effective for the Company beginning in the first quarter of fiscal year 2026, with early adoption permitted. The Company expects the new guidance will have an immaterial impact on its consolidated financial statements and intends to adopt the guidance when it becomes effective in the first quarter of fiscal year 2026.
In September 2025, the FASB issued ASU 2025-06 “Targeted improvements to the Accounting for Internal-Use Software” which is an update to remove all references to prescriptive and sequential software development stages (referred to as “project stages”). This ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact that the adoption of ASU 2025-06 may have on its consolidated financial statements.

SunPower Acquisition
On
September 30, 2024, commencing the Company’s fourth quarter of fiscal 2024, the Company completed the acquisition of certain assets
and assumption of certain liabilities from SunPower Debtors for an aggregate cash consideration paid of $
Transaction
costs incurred in connection with the close of the SunPower Acquisition totaled $
The fair values of assets acquired and liabilities
assumed were based upon a preliminary valuation. Consistent with previous disclosures, the Company disclosed that further adjustments
to the Company’s inventory were expected in the thirty-nine week period ended September 28, 2025. As of September 28, 2025,
the Company finalized the fair value of the assets acquired and liabilities assumed. The inventory acquired related to 1) work-in-progress
at various stages of completion as of the acquisition date for which further analysis was required in order to determine which systems
could be sold to a financing partner (for which the remaining units determined to be sellable to that partner were resolved during the
thirteen-weeks ended September 28, 2025) and 2) completed systems that were acquired as of the acquisition date for which uncertainty
existed due to unsettled matters with the SunPower Bankruptcy Estate (which were resolved in connection with the Company’s settlement
with the SunPower Bankruptcy Estate). The final determination of the fair values of the inventory and intangibles upon settlement of these
matters resulted in a revision to the inventory and intangibles with the offsetting adjustment to goodwill during the measurement period.
The Company concluded that the finalization of the measurement period adjustment resulted in the recognition of $

The fair values of assets acquired and liabilities assumed were based upon a preliminary valuation, and the Company’s estimates and assumptions are subject to change within the measurement period. Due to the timing of the acquisition at the end of the September 28, 2025 quarterly period, the purchase price accounting remains open for the components of working capital, identification and valuation of intangibles and allocation of goodwill to reportable segments. The Company has elected the practical expedient within ASC 805-20-30-27 through 805-20-30-30 to recognize and measure contract liabilities in accordance with ASC 606 – Revenue from Contracts with Customers as if it had originated the acquired contract. Thus, the amount of any contract liabilities immediately prior to the acquisition will be the comparable amounts recognized in the determination of assets acquired and liabilities assumed by the Company.
The following table summarizes the provisional fair value of identifiable assets acquired and liabilities assumed (in thousands):
| Net assets acquired: | ||||

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 would not have a material adverse effect on the business, financial position, results of operations, or cash flows of the Company.
Settlement of dispute with SunPower Debtors Bankruptcy Estate
Following the consummation of the acquisition of certain assets and assumption of certain liabilities of SunPower Debtors on September 30, 2024, certain matters pertaining to the acquisition were under dispute which included 1) amounts owed to and from the buyer and seller with respect to amounts in escrow related to the consideration transferred, 2) the right to the cash acquired in the acquisition, and 3) the right for the Company to sell and collect for certain solar systems that were acquired as a part of the acquisition that were sold or are to be sold to homebuilders within the New Homes Business. On June 25, 2025, all matters under dispute were resolved by the Company and the SunPower Bankruptcy Estate. Matters 1) and 2) were resolved such that no amounts will be paid (or received) by the Company. Matter 3) was resolved such that the Company has the right to sell the related inventory acquired and collect the underlying sales price for the sale of the solar system. In connection with each system sold, the Company is required to remit a portion of the sales price to the SunPower Bankruptcy Estate. The impact of the related settlement is not anticipated to be material.
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 the Company’s business, financial position,
results of operations, or cash flows. The Company has a loss contingency for legal settlements of $

SolarPark litigation

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 $
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’s 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, Solaria filed a Notice of Withdrawal of Appeal and will not appeal the Court’s Preliminary Injunction Order. Between August 2023 and March 2024, the parties were engaged in discovery negotiations and the Company produced documents to SolarPark. The Company produced its last set of documents on March 14, 2024. On August 14, 2025, the Court held a virtual hearing and revived the case. SolarPark subsequently amended the complaint, and the Company responded on October 14, 2025, with a motion to dismiss the complaint in its entirety. The Company also believes it has valid counterclaims to pursue against SolarPark. The litigation remains ongoing.
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 Government Technologies, Inc. (“Siemens Government Technologies”) filed a lawsuit against Solaria
Corporation in Fairfax Circuit Court (the “Court”) in Fairfax, Virginia. On July 27, 2023, Siemens Government Technologies
moved to amend the complaint to add Siemens Industry Inc. as a co-plaintiff. This motion was granted on August 25, 2023. On October 23,
2023, Siemens Government Technologies and Siemens Industry Inc. (collectively, “Siemens”) and Solaria Corporation stipulated
to add Solar CA, LLC as a co-defendant. Solaria Corporation and Solar CA, LLC (collectively, the “Subsidiaries”) are both

In addition to the above, on August 19, 2024, Siemens applied for the enforcement to a sister state judgment in the Superior Court of Alameda, California and the court entered a judgement in favor of Siemens. On December 9, 2024, Siemens moved to amend the judgment to add the Company as a judgement debtor. The Subsidiaries opposed the Siemens motion. On June 30, 2025, the California court found that the Company should be added as a judgment debtor party in California. In addition, the parties argued the appeal of the underlying Virginia litigation on July 24, 2025. On September 23, 2025, the Virginia Court of Appeals issued a decision on the appeal, affirming the original lower court decision and judgment against the Company.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion and analysis of our financial condition and results of operations together with the unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on April 30, 2025, and related management’s discussion and analysis in Item 7 of the Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Please also see the section titled “Special Note Regarding Forward-Looking Statements.”
Overview
SunPower Inc. (“SunPower” or the “Company”) is the rebranded name of Complete Solaria, Inc. Complete Solaria, Inc. was formed in November 2022 through the merger of Complete Solar and The Solaria Corporation. Founded in 2010, Complete Solar created a technology platform to offer clean energy products to homeowners by enabling a national network of sales partners and build partners. Our sales partners generate solar installation contracts with homeowners on our behalf. To facilitate this process, we provide the software tools, sales support and brand identity to our sales partners, making them competitive with national providers. This turnkey solution makes it easy for anyone to sell solar.
We fulfill our customer contracts by using in-house installation experts and by engaging with local construction specialists. We manage the customer experience and complete all pre-construction activities prior to delivering build-ready projects including hardware, engineering plans, and building permits to our builder partners. We manage and coordinate this process through our proprietary software system.
As further discussed below and above (Note 15 – Segment Information), we have three reportable segments: Residential Solar Installation, New Homes Business and Sunder Energy (“Sunder”).
There is substantial doubt about our ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued. The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q 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 our ability to continue as a going concern.

Growth strategy and outlook
Our growth strategy contains the following elements:
| ● | Increase revenue by
expanding installation capacity and developing new geographic markets – We continue to expand our network of partners who
will install systems resulting from sales generated by our sales partners. By leveraging this network of skilled builders in addition
to our in-house installation experts, we aim to increase our installation capacity in our traditional markets and expand our offering
into new geographies throughout the U.S. This will enable greater sales growth in existing markets and create new revenue in expansion
markets.
On September 30, 2024, upon approval by the Bankruptcy Court for the District of Delaware, we completed the acquisition of certain assets relating to the Blue Raven Solar Business, New Homes Business and non-Installing Dealer network previously operated by SunPower Debtors. On September 24, 2025, we completed the acquisition of Sunder, a residential solar sales company. The acquisition of Sunder expanded our footprint from 22 to 45 states. By doubling our dealer network salesforce to 1,744 this allows for further reach into new geographic markets where we were not previously concentrated. This acquisition will position us to be lone of the largest residential solar provider in the U.S.
Sunder’s established relationships with Electrical, Permit and Connection companies (“EPC”) will allow us to expand into markets where we do not have install capacity due to limitations of not being able to hire a skilled installation workforce due to lack of density. By leveraging a preferred network of EPCs this allows us to accelerate our growth, while keeping our overhead costs low.
By leveraging Sunder existing operating platform, our dealer network will be able to focus on delivering superior customer service to homeowners, while providing options to the homeowner based on their preferences. |
| ● | Increase revenue and margin by engaging national-scale sales partners – We aim to offer a turnkey solar solution to prospective sales partners with a national footprint. These include electric vehicle manufacturers, national home security providers, and real estate brokerages. We expect to create a consistent offering with a single execution process for such sales partners throughout their geographic territories. These national accounts have unique customer relationships that we believe will facilitate meaningful sales opportunities and low cost of acquisition to both increase revenue and improve margin. |
| ● | Increase revenue and margin by executing on 200,000-unit battery storage opportunity – We have an opportunity to increase our revenue and margin in the battery space through our partnership with Enphase. By providing homeowners with an option to include battery storage as part of their solar system install, we believe there will be a greater need for battery storage as the demand and costs of energy will increase. |
39
Mergers
We entered into an Amended and Restated Business Combination Agreement with FACT, First Merger Sub, Second Merger Sub, and Solaria on October 3, 2022. The Merger was consummated on July 18, 2023. Upon the terms and subject to the conditions of the Merger, (i) First Merger Sub merged with and into Complete Solaria with Complete Solaria surviving as a wholly-owned subsidiary of FACT (the “First Merger”), (ii) immediately thereafter and as part of the same overall transaction, 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 FACT changed its name to “Complete Solaria, Inc.” and Second Merger Sub changed its name to “CS, LLC” and (iii) immediately after the consummation of the Second Merger and as part of the same overall transaction, Solaria merged with and into a newly formed Delaware limited liability company and wholly-owned subsidiary of FACT and changed its name to “The SolarCA 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”).
The Mergers between Complete Solaria and FACT has been accounted for as a reverse recapitalization. Under this method of accounting, FACT was treated as the acquired company for financial statement reporting purposes. This determination was primarily based on the Company having a majority of the voting power of the post-combination company, the Company’s senior management comprising substantially all of the senior management of the post-combination company, and the Company’s operations comprising the ongoing operations of the post-combination company. Accordingly, for accounting purposes, the Mergers have been treated as the equivalent of a capital transaction in which Complete Solaria is issuing stock for the net assets of FACT. The net assets of FACT have been stated at historical cost, with no goodwill or other intangible assets recorded.
Disposal transaction
In October 2023, we completed the divestiture of our solar panel business to Maxeon (“Divestiture”), pursuant to the terms of a disposal agreement (“Disposal Agreement”). Under the terms of the Disposal Agreement, Maxeon agreed to acquire from the Company certain assets and employees, for an aggregate purchase price of approximately $11.0 million consisting of 1,100,000 shares of Maxeon ordinary shares. We determined that the criteria were met for discontinued operations classification as the divestiture represented a strategic shift in our business. In connection with the Divestiture, we recognized a loss from discontinued operations of $2.0 million and $173.4 million in the fiscal years ended December 29, 2024 and December 31, 2023, respectively. We also sold all the Maxeon shares in the year ended December 31, 2023, and recorded a $4.2 million loss on the sale of these shares in our consolidated statements of operations and comprehensive loss.
Following is a discussion of our historical results of operations, which excludes product revenues and metrics related to the disposal, as all results of operations associated with the solar panel business have been presented as discontinued operations, unless otherwise noted.
SunPower acquisition transaction
On August 5, 2024, we entered into an asset purchase agreement among us and SunPower Corporation and SunPower Corporation’s direct and indirect subsidiaries (“SunPower Debtors”) which provided for the purchase of certain assets relating to the Blue Raven Solar business, New Homes Business and Non-Installing Dealer network previously operated by the SunPower Debtors (the “Acquired SunPower Assets”). The sale by the SunPower Debtors was approved on September 23, 2024, by the United States Bankruptcy Court for the District of Delaware. We completed the acquisition (“SunPower Acquisition”) of the Acquired SunPower Assets (“SunPower Businesses”) effective September 30, 2024.
We financed the SunPower Acquisition by issuing 7.0% senior unsecured convertible notes (“7.0% Senior Notes”) in September 2024, which are due in 2029. The 7.0% Senior Notes mature on July 1, 2029 and are convertible into shares of our common stock at the option of the holder at a conversion rate of $2.14 per share. The 7.0% Senior Notes will become immediately due and payable at the option of the holder in the event of default and upon a qualifying change of control event.
Sunder Energy acquisition transaction
On September 21, 2025, we entered into an agreement to acquire Sunder Energy (“Sunder”) and completed the acquisition effective September 24, 2025 (“Sunder Acquisition”). The acquisition was completed through the acquisition of all of the Membership Interests of Sunder for aggregate consideration of $57.8 million consisting of cash, a note issued to the seller, 3,333,334 shares of our common stock issued as of the acquisition date plus an additional 3,333,333 shares to be issued on each of the 12-month and 18-month anniversaries of the closing of the acquisition. The shares of our common stock were valued at $17.1 million at the date of acquisition. This transaction was accounted for as a business combination in accordance with ASC 805, Business Combinations. The financial results of Sunder have been included in our unaudited condensed consolidated financial statements since the date of acquisition.
40
We financed the Sunder Acquisition through the issuance of a $20.0 million note (“Seller Note”) with an interest rate of 7.0% and due the earlier of (i) May 15, 2026 and (ii) the date on which all amounts under the Seller Note otherwise become due and payable following an event of default and the issuance of $22.0 million of 7.0% senior unsecured convertible notes due July 1, 2029.
Key financial definitions/components of results of operations
Revenues
Revenue is recognized for Residential Solar Installation and New Homes Business when a customer obtains control of promised products and services and we have satisfied our performance obligations which is the date by which substantially all of our design and installation is complete for a fully functioning solar power system to interconnect to the local power grid.
Installation includes the design of a solar energy system, the delivery of the components of the solar energy system (i.e., photovoltaic system, inverter, battery storage, etc.), installation services and services facilitating the connection of the solar energy system to the power grid. We account for these services as inputs to a combined output, resulting in a single service-based performance obligation.
The amount of revenue recognized reflects the consideration which we expect to be entitled to receive in exchange for the products and services. To achieve this core principle, we apply the following five steps:
Step 1. Identification of the contract(s) with a customer;
Step 2. Identification of the performance obligations in the contracts(s);
Step 3. Determination of the transaction price;
Step 4. Allocation of the transaction price to the performance obligations;
Step 5. Recognition of the revenue when, or as, we satisfy a performance obligation.
Residential Solar Installation revenues
Our Residential Solar Installation segment sells products through a network of installing and non-installing dealers and resellers, as well as our internal sales team. Our contracts with customers include three primary contract types:
| ● | Cash agreements – We contract directly with homeowners who purchase the solar energy system and related services from us. Customers are invoiced on a billing schedule, where the majority of the transaction price is due upon installation with an additional payment due when the system passes inspection by the authority having jurisdiction. |
| ● | Financing partner agreements – In our financing partner agreements, we contract directly with homeowners for the purchase of the solar energy system and related services. We refer the homeowner to a financing partner to finance the system, and the homeowner makes payments directly to the financing partner. We receive consideration from the financing partner on a billing schedule where the majority of the transaction price is due upon installation with an additional payment due when the system passes inspection by the authority having jurisdiction. |
| ● | Power purchase agreements and lease agreements – We contract directly with a leasing partner to perform the solar energy system installation, and the homeowner will finance the system through a power purchase agreement (or lease), which is signed with our leasing partner. We consider the leasing partner to be our customer, as we do not contract directly with the homeowner and the leasing partner takes ownership of the system upon the completion of installation. We receive consideration from the leasing partner on a billing schedule where the majority of the transaction price is due upon installation with an additional payment due when the system passes inspection by the authority having jurisdiction. |
41
New Homes Business revenues
Our New Homes Business segment sells through a network of home builders as well as our internal sales team. Our contracts with customers include two primary contract types:
| ● | Cash agreements – We contract directly with homebuilders who purchase the solar energy system from us and are the customers in the transaction. Our customers are invoiced upon the completion of installation. |
| ● | Lease agreements – Prior to the SunPower Debtor’s declaration of bankruptcy, certain homeowners had intended to lease a system from SunPower Debtors, but were unable to consummate the transaction (as a result of SunPower Debtor’s declaration of bankruptcy). The in-process system inventory (installed on recently constructed homes) was acquired by us in connection with the SunPower Acquisition. We contracted directly with a leasing partner to facilitate the leasing of the system to the impacted homeowners. We consider the leasing partner to be our customer. Under the terms of our arrangement with the leasing partner, control is not transferred to the customer until the completed system is accepted by the customer. We receive consideration from the leasing partner following the acceptance of the system. |
Our performance obligation for both reportable segments is to design and install a fully functioning solar energy system. For all contract types (with the exception of New Homes Business Lease agreements), we recognize revenue over time. Our over-time revenue recognition begins when the solar power system is fully installed (as it is at this point that control of the asset begins to be transferred to the customer and the customer retains the significant risks and rewards of ownership of the solar power system). We recognize revenue using the input method based on direct costs to install the system and defer the costs of installation until such time that control of the asset transfers to the customer (installation). For New Homes Business Lease agreements, we consider the performance obligation to be satisfied at a point in time upon acceptance of the system by the customer.
Revenue is generally recognized at the transaction price contained within the agreement, net of costs of financing, or other consideration paid to the customers that is not in exchange for a distinct good or service. Our arrangements may contain clauses that can either increase or decrease the transaction price. Variable consideration is estimated at each measurement date at its most likely amount to the extent that it is probably that a significant reversal of cumulative revenue recognized will not occur and true-ups are applied prospectively as such estimates change.
We record deferred revenue for amounts invoiced that are received in advance of the provisioning of services. In certain contracts with customers, we arrange for a third-party financing partner to provide financing to the customer. We collect upfront from the financing partner and the customer will provide installment payments to the financing partner. We record revenue in the amount received from the financing partner, net of any financing fees charged to the homeowner, which we consider to be a customer incentive. None of our contracts contain a significant financing component.
Sunder
We earn revenue from contracts sold to customers for solar installations performed by third-party installation companies. We recognize revenue at a point in time when Permission to Operate (“PTO”) is complete. We act as an agent in these arrangements and record revenue on a net basis. We do not have significant financing components in our contracts. We do not provide warranty services and do not record a warranty reserve.
Costs to obtain and fulfill contracts
Our costs to obtain and fulfill contracts, when recognized, associated with systems sales are expensed as sales commission and cost of revenue, respectively. In addition, incentives we provide to our customers, such as discounts and rebates, are recorded net to the revenue we have recognized on the solar power system.
Cost of revenues
Cost of revenues is comprised primarily of cost of material, internal labor costs, third-party subcontractors, design services, engineering personnel and employee-related expenses associated with permitting services, associated warranty costs, freight and delivery costs, depreciation, and amortization of internally developed software. Cost of revenues from these services is recognized when we transfer control of the product to the customer, which is generally upon installation.
42
Operating expenses
Sales commissions
Sales commissions are direct and incremental costs of obtaining customer contracts. These costs are paid to internal sales teams and third-party vendors who source residential customer contracts for the sale of solar energy systems.
Sales and marketing
Sales and marketing expenses primarily consist of personnel related costs, including salaries and employee benefits, stock-based compensation, and other promotional and advertising expenses. We expense certain sales and marketing, including promotional expenses, as incurred.
General and administrative
General and administrative expenses consist primarily of personnel and related expenses for employees, in our finance, research, engineering, and administrative teams including salaries, bonuses, payroll taxes, and stock-based compensation. It also consists of legal, consulting, and professional fees, rent expenses pertaining to our offices, business insurance costs and other costs.
Interest expense
Interest expense primarily relates to interest expense on the issuance of debt and convertible notes and the amortization of debt issuance costs.
Other expense, net
Other expense, net consists of changes in the fair value of our derivative liabilities in connection with our convertible notes and changes in the fair value of common stock warrant liabilities, forward purchase agreements, and SAFE Agreements.
Income tax expense
Income tax expense primarily consists of income taxes in certain jurisdictions in which we conduct business.
Supply chain constraints and risk
The global supply chain and our industry have experienced significant disruptions in recent periods. We have seen supply chain challenges and logistics constraints increase, including shortages of panels, inverters, batteries and associated component parts for inverters and solar energy systems available for purchase, which materially impacted our results of operations. These shortages and delays can be attributed in part to the broader macroeconomic conditions and have been exacerbated by the conflicts in Ukraine and Israel. If any of our suppliers of solar modules experienced disruptions in the supply of the modules’ component parts, for example semiconductor solar wafers or inverters, this may decrease production capabilities and restrict our inventory and sales. In addition, we have experienced and are experiencing varying levels of volatility in costs of equipment and labor resulting in part from disruptions caused by general global economic conditions. While inflationary pressures have resulted in higher costs of products, in part due to an increase in the cost of the materials and wage rates, these additional costs have been offset by the related rise in electricity rates.
We cannot predict the full effects the supply chain constraints will have on our business, cash flows, liquidity, financial condition and results of operations at this time due to numerous uncertainties. Given the dynamic nature of these circumstances on our ongoing business, results of operations and overall financial performance, the full impact of macroeconomic factors, including the conflicts in Ukraine and Israel, cannot be reasonably estimated at this time. In the event we are unable to mitigate the impact of delays or price volatility in solar energy systems, raw materials, and freight, it could materially adversely affect our business, prospects, financial condition and results of operations.

Other expense, net
Other expense, net for the thirty-nine weeks ended September 28, 2025, was $1.7 million. The main drivers consisted of $3.1 million of expense associated with the change in the fair value of our public, private placement and working capital warrants which are accounted for as liabilities and $0.8 million arising from the change in the fair value of our forward purchase agreements. These expenses were partially offset by $1.6 of gains from changes in the fair value of derivative liabilities associated with our 12% and 7% senior unsecured convertible notes.
We had other expense, net of $66.2 million, in the thirty-nine weeks ended September 29, 2024, which was comprised of $62.6 million related to the recognition of a derivative liability and subsequent change in fair value, $3.8 million of other financing costs, $2.1 million of expense incurred on the conversion and changes in the fair value our SAFE Agreements, $2.1 million of expense arising from changes in the fair value of warrants issued for our common stock and $0.5 million of other expenses partially offset by income of $4.9 million related to changes in the fair value of our forward purchase agreements.
Net loss from continuing operations
As a result of the factors discussed above, our net loss from continuing operations for the thirty-nine weeks ended September 28, 2025 was $30.1 million, as compared to a net loss from continuing operations of $101.4 million in the thirty-nine week period ended September 29, 2024.

Liquidity and capital resources
Overview
Since inception, we have incurred losses and negative cash flows from operations. We had a net loss from continuing operations of $30.1 million in the thirty-nine week period ended September 28, 2025. As of September 28, 2025, we had an accumulated deficit of $442.6 million, total debt, including derivative liabilities of $204.3 million, and cash and cash equivalents (excluding restricted cash) of $5.1 million which was held for working capital expenditures. We believe our operating losses and negative operating cash flows will continue into the foreseeable future.
Our material cash requirements include cash required to fund our operations, to meet our working capital requirements and to fund our capital expenditures.
We have financed our operations primarily through sales of equity securities, debt, issuance of convertible notes, cash generated from operations and the proceeds from the Mergers. As a result of not timely filing our Annual Report on Form 10-K for the fiscal year ended December 29, 2024, we are not currently eligible to use a registration statement on Form S-3 that would allow us to continuously incorporate by reference our SEC reports into the registration statement, to use “shelf” registration statements to conduct offerings, or to use our at-the-market offering facility until approximately one year from the date we have regained and maintained status as a current filer. Our inability to use Form S-3 may significantly impair our ability to raise the necessary capital to fund our operations and execute our strategy. If we seek to access the capital markets through a registered offering during the period of time that we are unable to use Form S-3, we may be required to publicly disclose the proposed offering and the material terms thereof before the offering commences, we may experience delays in the offering process due to SEC review of a Form S-1 registration statement and we may incur increased offering and transaction costs and other considerations. If we are unable to raise capital through a registered offering, we would be required to conduct our equity financing transactions on a private placement basis, which may be subject to pricing, size and other limitations imposed under the Nasdaq rules, or seek other sources of capital. The foregoing limitations on our financing approaches could prevent us from pursuing transactions or implementing business strategies that would be beneficial to our business.
Our cash equivalents are on deposit with major financial institutions. Our cash position raises substantial doubt regarding our ability to continue as a going concern for 12 months following the issuance of the unaudited condensed consolidated financial statements.
We will receive the proceeds from any cash exercise of warrants for shares of our common stock. The aggregate amount of proceeds could be up to $257.2 million if all the warrants are exercised for cash. However, to the extent the warrants are exercised on a “cashless basis,” the amount of cash we would receive from the exercise of those warrants will decrease. The Private Warrants and Working Capital Warrants, as so identified in our unaudited condensed consolidated financial statements, may be exercised for cash or on a “cashless basis.” The Public Warrants and the Merger Warrants may only be exercised for cash provided there is an effective registration statement registering the shares of common stock issuable upon the exercise of such warrants. If there is not a then-effective registration statement, then such warrants may be exercised on a “cashless basis,” pursuant to an available exemption from registration under the Securities Act of 1933, as amended (“Securities Act”). We expect to use any such proceeds for general corporate and working capital purposes, which would increase our liquidity. As of December 18, 2025, the price of our common stock was $1.74 per share. The weighted average exercise price of the warrants was $10.02 as of September 28, 2025. We believe the likelihood that warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we would receive is dependent upon the market price of our common stock. If the market price for our common stock remains less than the exercise price, we believe warrant holders will be unlikely to exercise.

Debt financings
12.0% unsecured convertible senior notes
In July 2024, we issued $46.0 million of senior unsecured convertible notes (“July 2024 Notes”) to various lenders in connection with the exchange agreement transactions summarized below. Of the July 2024 Notes, $18.0 million were issued in exchange for the cancellation of existing indebtedness, which amount included $10.0 million issued to CRSEF Solis Holdings, LLC and its affiliates (“Carlyle”), identified by us as a related party at the transaction date. During the thirteen week period ended June 29, 2025, Carlyle ceased to be a significant shareholder and therefore is no longer deemed a related party with the Company. The July 2024 Notes also include $18.0 million initially issued to a related party affiliated with the Company’s CEO, Rodgers Massey Revocable Living Trust (“Rodgers Revocable Trust”). The July 2024 Notes bear interest at 12.0% per annum and mature on July 1, 2029. The interest rate increases by 3% in the event of default. Interest is payable semiannually in arrears on January 1 and July 1. The July 2024 Notes are convertible into shares of our common stock at the option of the holder at a conversion rate initially equal to 595.2381 shares of common stock per $1,000 principal amount of the July notes. The July 2024 Notes may be declared due and payable at the option of the holder upon an event of default and upon a qualifying change of control event.
On July 10, 2025, the Company issued a convertible promissory note (the “July 2025 Note”) to the Rodgers Revocable Trust in exchange for $5.0 million of proceeds received by the Company. The July 2025 Note bears the same features as the July 2024 Notes except for the conversion rate which is initially equal to 558.6592 shares of common stock per $1,000 principal amount due under the July 2025 Note. The conversion rate is subject to adjustment from time to time pursuant to the terms of the July 2025 Note. The July 2025 Note matures on July 1, 2029.
7.0% unsecured convertible senior notes
In September 2024, we issued $66.8 million of senior unsecured convertible notes to various lenders (the “September 2024 Notes”), $8.0 million of which were issued to a related party. In December 2024, we issued additional September 2024 Notes for cash proceeds of $13.0 million, and we issued an additional $0.2 million of the September 2024 Notes in the thirteen week period ended March 30, 2025. The September 2024 Notes bear interest at 7.0% per annum and mature on July 1, 2029. Interest is payable semiannually in arrears on January 1 and July 1.The September 2024 Notes are initially convertible into 467.8363 shares of common stock per $1,000 principal amount of September 2024 Notes. The September 2024 Notes may be declared due and payable at the option of the holder upon an event of default and upon a qualifying change of control event.
In September 2025, we issued an additional $22.0 million of the 7.0% unsecured senior convertible notes to various creditors (“September 2025 Notes”) for net proceeds of $19.6 million which was used to fund our acquisition of Sunder.
Seller Note
In addition to the September 2025 Notes to finance the acquisition of Sunder, we also issued a note to the seller of Sunder (“Seller Note”) on September 24, 2025. The Seller Note has an original principal amount of $20.0 million. The Seller Note bears interest at 7.0% per annum, compounded at the end of each calendar quarter. Interest is due and payable concurrent with the payment of the principal balance. The maturity date under the Seller Note is the earlier of (i) May 15, 2026 and (ii) the date on which all amounts under the Seller Note otherwise become due and payable following an event of default. The Seller Note must also be repaid in the event of a change of control of the Company or the sale of all or substantially all of the consolidated assets of the Company and its subsidiaries. The Seller Note includes customary events of default, including: (a) our failure to pay the Seller Note when due, (b) our voluntary or involuntary bankruptcy, (c) our liquidation or dissolution, (d) a change of control of the Company, (e) our material breach of the covenants applicable to us under the Seller Note, subject to applicable cure periods, and (f) if any of our representations or warranties made in the Seller Note were untrue in any material respect when made.
Loan with related party
We have a fixed principal balance of $1.5 million outstanding as of September 28, 2025, due to the Rodgers Revocable Trust, a related party.
Forward purchase agreements
In July 2023, FACT and Legacy Complete Solaria, Inc. entered into FPAs with each of (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) Sandia Investment Management LP (“Sandia”) , and (iii) Polar Multi-Strategy Master Fund (“Polar”) (each individually, a “Seller”, and together, the “FPA Sellers”).
51
Pursuant to the terms of the FPAs, the FPA Sellers may 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 FPAs 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 Counterparty at 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. |
We 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, we 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.
On December 18, 2023, we and the FPA Sellers entered into separate amendments to the FPA (the “Amendments”). The Amendments lowered the reset floor price of each FPA from $5.00 to $3.00 and allow us to raise up to $10.0 million of equity from existing stockholders without triggering certain anti-dilution provisions contained in the FPA; 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.
On May 7 and 8, 2024, respectively, we entered into and executed separate amendments to the FPAs (collectively the “Second Amendments”) with Sandia (the “Sandia Second Amendment”) and Polar (the “Polar Second Amendment”). The Second Amendments lowered the reset price of each FPA from $3.00 to $1.00 per share and amended 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 we execute similar amendments with both Polar and Meteora.
52
On June 14, 2024, we entered into and executed an amendment to the FPA with Sandia (the “Sandia Third Amendment”). The Sandia Third Amendment set the reset price of each FPA to $1.00 per share and amended 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.”
On July 17, 2024, we entered into an amendment to the FPA with Polar pursuant to which we and Polar agreed that Section 2 (Most Favored Nation) of the FPA is applicable to all 2,450,000 shares subject to the FPA.
On July 15, 2025, we and Meteora entered into an amendment to the FPA between Meteora and us, on July 16, 2025, we and Sandia entered into an amendment to the FPA between Sandia and us, and on August 1, 2025, we and Polar entered in an amendment to the FPA between Polar and us (collectively, the “FPA Amendments”).
The FPA Amendments extend the valuation date applicable to the Forward Purchase Agreements (the “Valuation Date”) to the earliest to occur of (a) July 17, 2026, (b) the date specified by Meteora or Sandia, as applicable, in a written notice to be delivered to the Company at their discretion and (c) 90 days after delivery by us of a written notice in the event that for any 20 trading days during a 30 consecutive trading day-period that occurs at least six months after the closing date of the transactions under the Amended and Restated Business Combination Agreement entered into on May 26, 2023, the applicable volume-weighted average price (“VWAP Price”) is less than the then applicable reset price, provided that a registration statement was effective and available for the entire measurement period and remains continuously effective and available during the entire 90 day notice period.
The FPA Amendments further amend the definition of “Settlement Amount Adjustment” to provide that if the expected Settlement Amount (as defined in the FPA Amendments) determined by the VWAP Price over the 15 scheduled trading days ending on but excluding the valuation date exceeds the Settlement Amount Adjustment, then the Settlement Amount Adjustment shall be deemed to be zero, and that if the Settlement Amount Adjustment exceeds the Settlement Amount, then the Settlement Amount Adjustment shall be paid, at our option, in cash or shares of the our common stock.
The FPA Amendments also amend the definition of “Cash Settlement Payment Date” to provide that if the Settlement Amount Adjustment exceeds the Settlement Amount, we shall remit to the applicable seller the difference between (i) the Settlement Amount Adjustment and (ii) the Settlement Amount. The FPA Amendments further provide that the Settlement Amount will be used solely as a calculation mechanism to determine any liability we may owe to the applicable seller via the Settlement Amount Adjustment, and notwithstanding anything to the contrary, the applicable seller shall not be required to remit the Settlement Amount to us or return any portion of the Prepayment Amount.
Simple agreement for future equity (“SAFE”) agreements
First SAFE
On January 31, 2024, we entered into a SAFE (“First SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (the “Purchaser”) in connection with the Purchaser investing $1.5 million in the Company. The First SAFE is convertible into shares of our 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 we issue and sell common stock at a fixed valuation (an “Equity Financing”), at a per share conversion price which is equal to the lower of (i) (a) $53.54 million divided by (b) our capitalization immediately prior to such Equity Financing (such conversion price, the “SAFE Price”), and (ii) 80% of the price per share of our common stock sold in an Equity Financing transaction. If we consummate a change of control prior to the termination of the First SAFE, the Purchaser will be 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 our common stock equal to (a) $1.5 million divided by (b)(1) $53.54 million divided by (2) our 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 our common stock, assuming a per share conversion price of $1.05, which is the product of (i) $1.31, the closing price of our common stock on January 31, 2024, multiplied by (ii) 80%.
On April 21, 2024, we entered into an amendment (“First SAFE Amendment”) that converted the First SAFE investment of $1.5 million into 4,166,667 shares of our common stock based on a conversion price of $0.36 per share, defined in the First SAFE Amendment as the product of (i) $0.45, the closing price of our common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, we recorded a debit to SAFE Agreement of $1.5 million, a credit to Additional paid-in-capital of $1.9 million and recognized expense of $0.4 million within Other expense, net in our results of operations for that period.
53
Second SAFE
On February 15, 2024, we entered into a second SAFE (the “Second SAFE”) with the Purchaser, in connection with the Purchaser investing $3.5 million in the Company. The Second SAFE did not accrue interest. The Second SAFE was initially convertible into shares of our common stock upon the initial closing of an Equity Financing transaction at a per share conversion price which was equal to the lower of (i) the Second SAFE Price, and (ii) 80% of the price per share of our common stock sold in such Equity Financing. If we 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 our 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 our 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 our common stock on February 15, 2024, (ii) 80%.
On April 21, 2024, we entered into an amendment (“Second SAFE Amendment”) that converted the Second SAFE investment of $3.5 million into 9,722,222 shares of our common stock based on a conversion price of $0.36 per share, defined in the Second SAFE Amendment as the product of (i) $0.45, the closing price of our common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, we recorded a debit to SAFE Agreement of $3.5 million, a credit to Additional paid-in-capital of $4.4 million and recognized expense of $0.9 million within Other expense, net in our results of operations for that period.
Third SAFE
On May 13, 2024, we entered into a third SAFE (the “Third SAFE”) with the Purchaser, in connection with the Purchaser investing $1.0 million in the Company. The Third SAFE is convertible into shares of our common stock 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 issues and sells shares of its common stock in an Equity Financing transaction, at a per share conversion price which is equal to 50% of the price per share of our common stock sold in such Equity Financing transaction. If we consummate a change of control prior to the termination of the Third SAFE, the Purchaser will be automatically entitled to receive a portion of the proceeds of such liquidity event equal to $1.0 million, subject to certain adjustments as set forth in the Third SAFE. The Third SAFE is convertible into a maximum of 2,750,000 shares of our common stock, assuming a per share conversion price of $0.275, which is the product of (i) $0.55, the closing price of our common stock on May 13, 2024, multiplied by (ii) 50%. Given that the SAFE could be settled in cash or a variable number of shares, we have accounted for the instrument as a liability at its fair value.
As September 28, 2025, we estimated the fair value of the Third SAFE at $0.5 million based upon the assumptions disclosed in Note 4 – Fair Value Measurements to our unaudited condensed consolidated financial statements.
Cash flows for the thirty-nine weeks ended September 28, 2025 and September 29, 2024
The following table summarizes our cash flows from operating, investing, and financing activities for the thirty-nine week periods ended September 28, 2025 and September 29, 2024 (in thousands):
| Thirty-Nine Weeks Ended | ||||||||
| September 28, 2025 | September 29 2024 | |||||||

54
Cash flows from operating activities
Net cash used in operating activities from continuing operations of $13.4 million in the thirty-nine weeks ended September 28, 2025 was due to net loss from continuing operations of $30.1 million offset by $33.8 million of favorable noncash adjustments and $17.1 million of cash outflows from changes in operating assets and liabilities. Significant movement in non-cash adjustments consisted of favorable non-cash adjustments of $14.3 million of amortization of debt issuance costs, $8.2 million of stock-based compensation, $4.3 million of depreciation and amortization, $3.1 million for the change in the fair value of warrant liabilities, $4.2 million for the provision of credit losses, $0.8 million of non-cash lease expense and $0.8 million change in the fair value of forward purchase agreements, partially offset by $1.6 million net gain on the change in the fair value of derivative liabilities and $0.3 million of other items. Significant movement attributable to net cash outflows from changes in operating assets of $17.1 million consisted of a $32.7 million increase in accounts receivable, a $12.3 million increase in prepaid expenses and other current assets and noncurrent assets, a $6.4 million decrease in accrued expenses and other liabilities, a $10.6 million decrease in contract liabilities, and a $0.9 million decrease in operating lease obligations, partially offset by a $34.1 million decrease in inventories and a $11.7 million increase in accounts payable.
Net cash used in operating activities from continuing operations of $29.1 million for the thirty-nine weeks ended September 29, 2024 was primarily due to the net loss from continuing operations, net of tax of $101.4 million, partially offset by non-cash adjustments of $70.8 million and net cash inflows of $1.5 million from changes in our operating assets and liabilities. Non-cash adjustments in our operating results consisted of $62.6 million arising from the issuance and subsequent change in fair value of derivative liabilities in connection with our convertible notes issued and outstanding, $5.4 million of expense in connection with warrants issued for vendor services, $3.1 million of expense related to changes in provision for credit losses, $4.1 million of stock-based compensation expense, $3.7 million of loss on impairment of assets, $3.9 million of expense in accretion of interest attributable to the CS Solis debt, $3.8 million of other noncash financing costs, $1.9 million of non-cash interest expense, $1.3 million of loss arising from the conversion of two SAFE Agreements to shares of our common stock, $1.0 million of depreciation and amortization, $0.9 million of expense related to changes in the fair value of the SAFE Agreements, $2.1 million of loss from the changes in the fair value of our warrant liabilities, $1.4 million amortization of debt issuance costs, $0.5 million of lease expense and $0.1 million provision for excess and obsolete inventory. These adjustments were partially offset by a $19.9 million gain on extinguishment of debt, $4.9 million of income related to changes in fair value of our forward purchase agreements. The main drivers of net cash inflows derived from the changes in operating assets and liabilities were related to a decrease in accounts receivable, net of $14.7 million and a decrease in inventories of $2.4 million, partially offset by a decrease in accounts payable of $8.5 million, an increase in prepaid and other current assets of $3.2 million, a decrease in contract liabilities of $1.4 million, a decrease in accrued expenses and other liabilities of $1.6 million, and a decrease in operating lease liabilities of $0.9 million.
Cash flows from investing activities
Net cash used in investing activities from continuing operations of $20.7 million in the thirty-nine week period is attributable to the cash paid for the acquisition of Sunder. Net cash used of $1.0 million for the thirty-nine September 29, 2024 is attributable to additions to internal-use-software.
Cash flows from financing activities
Net cash provided by financing activities from continuing operations was $25.8 million for the thirty-nine weeks ended September 28, 2025 and consisted of $1.7 million in proceeds from the issuance of shares of our common stock, $5.0 million received from the Rodgers Revocable Trust, a related party in exchange for the July 2025 Note, $19.8 million received in exchange for 7% senior unsecured convertible notes, and $0.8 million in proceeds from the exercise of stock options and warrants in exchange for the issuance of shares of our common stock, partially offset by $1.5 million of finance leases payments.
Net cash provided by financing activities of $107.1 million for the thirty-nine weeks ended September 29, 2024 was primarily due to $94.7 million in net proceeds from the issuance of convertible notes, inclusive of $26.0 million from a related party, $6.1 million in net proceeds from the issuance of shares of our common stock from White Lion and $6.0 million in net proceeds from the issuance of SAFE Agreements, and $0.6 million of proceeds from the exercise of common stock options, partially offset by $0.3 million repayment of notes payable.
Emerging growth company status
Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, and any such election to not take advantage of the extended transition period is irrevocable.
Complete Solaria is an “emerging growth company” as defined in Section 2(a) of the Securities Act and has elected to take advantage of the benefits of the extended transition period for new or revised financial accounting standards. Following the closing of the Mergers, our Post-Combination Company remains an emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of common stock that is held by non-affiliates exceeds $700 million as of the end of that year’s second fiscal quarter, (ii) the last day of the fiscal year in which we has total annual gross revenue of $1.235 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which we have issued more than $1.0 billion in non-convertible debt in the prior three-year period, or (iv) the last day of the fiscal year ending after the fifth anniversary of our IPO. Complete Solaria expects to continue to take advantage of the benefits of the extended transition period, although it may decide to early adopt such new or revised accounting standards to the extent permitted by such standards. This may make it difficult or impossible to compare our financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Not applicable.
ITEM 4. CONTROLS AND PROCEDURES
Evaluation of disclosure controls and procedures
As of the end of the period covered by this Quarterly Report on Form 10-Q, we conducted an evaluation, under the supervision and with the participation of our Chief Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based on this evaluation, our Chief Executive Officer and Principal Financial Officer concluded that, as of September 28, 2025, such disclosure controls and procedures were not effective as a result of previously reported material weaknesses.
On September 24, 2025, we completed the Sunder acquisition. We are currently integrating Sunder into our overall internal control over the financial reporting process and, consistent with interpretive guidance issued by the staff of the Securities and Exchange Commission, we are excluding the business from our evaluation of disclosure controls and procedures as of September 28, 2025. In accordance with such guidance, an assessment recent business combinations may be omitted from management’s assessment of internal control over financial reporting for one year following the acquisition. This acquisition constituted approximately 3% of our consolidated total assets and approximately 2% of our consolidated revenues were generated from the operations acquired from Sunder as of and for the thirty-nine week period ended September 28, 2025.
Notwithstanding the foregoing, there were no changes to previously issued financial statements. Our Chief Executive Officer and Principal Financial Officer believe that the interim unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial condition, results of operations and cash flows as of and for the periods presented in accordance with U.S. GAAP.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses are as follows:
The Company did not maintain controls to execute the criteria established in the COSO Framework for (i) the control environment, (ii) risk assessment, (iii) control activities, (iv) information and communication, and (v) monitoring activities.
Each of the control deficiencies identified below constitute material weaknesses, either individually or in the aggregate.
Control Environment. The Company did not maintain an effective control environment and identified the following material weakness: the Company lacked appropriate policies and resources to develop and operate effective internal control over financial reporting and a lack of appropriate and consistent IT policies given the significant volume of financially relevant IT changes, which contributed to the Company’s inability to properly analyze, record and disclose accounting matters timely and accurately.
Management has developed and commenced a remediation plan to address the material weakness and strengthen the Company’s control environment. The plan includes implementing comprehensive internal control policies and formal IT governance procedures, including change management protocols for financially relevant IT systems and deploying tools to automate control activities and track IT changes impacting financial reporting.
Management is committed to completing these remediation efforts as promptly as possible. Until these measures are fully implemented and operating effectively, the material weakness will remain. The Company will continue to evaluate the effectiveness of its internal controls and provide updates in future filings as required under SEC rules.
56
This control environment material weakness also contributed to the other material weaknesses identified below.
Risk Assessment. The Company did not design and implement an effective risk assessment and identified a material weakness relating to: (i) identifying, assessing, and communicating appropriate objectives, (ii) identifying and analyzing risks to achieve these objectives, and (iii) identifying and assessing changes in the business that could impact the system of internal controls.
Control Activities. The Company did not design and implement effective control activities and identified the following material weakness:
| ● | Ineffective design and operation of certain control activities due to significant personnel changes throughout 2024. Control deficiencies, which aggregate to a material weakness, occurred within substantially all areas of financial reporting. |
Information and Communication. The Company did not design and implement effective information and communication activities and identified the following material weaknesses:
| ● | The Company did not design and maintain effective general information technology controls over logical access and program change management for our key information systems used to support the financial reporting process. Specifically, management did not maintain effective controls to ensure proper segregation of duties related to user administration and other privileged access functions and in implementing program changes in information systems. Due to the pervasive nature of these deficiencies, business process controls that are dependent upon information from these systems were also not effective. |
| ● | The Company did not have adequate processes and controls for communicating information among the accounting, finance, operations, and legal departments, necessary to support the proper functioning of internal controls. |
The Company did not design and maintain effective general information technology controls over logical access and program change management for key information systems supporting the financial reporting process. Specifically, management did not maintain effective controls to ensure proper segregation of duties related to user administration and other privileged access functions, and in implementing program changes in information systems. The Company also lacked adequate processes and controls for communication among the accounting, finance, operations, and legal departments necessary to support the proper functioning of internal controls.
To address these issues, management has established a dedicated cross-functional remediation team comprising members from IT, Finance, and Internal Audit. This team has been tasked with strengthening information technology general controls, improving segregation of duties, and implementing structured communication protocols between departments. The team is also developing enhanced management procedures and monitoring mechanisms to ensure sustainable compliance and effective internal control over financial reporting.
Monitoring Activities. The Company did not design and implement effective monitoring activities and identified the following material weaknesses: (i) failure to adequately monitor compliance with accounting policies, procedures and controls related to substantially all areas of financial reporting; and (ii) failure to properly select, develop and perform ongoing evaluations of the components of internal controls (including the monitoring of service providers’ control environments).
These material weaknesses described in the paragraphs above contributed to material accounting errors identified and corrected during the audit of the Company’s financial statements. If we fail to adequately remediate these material weaknesses, there could be material misstatements that may not be prevented or detected.
57
Remediation Plan and Status. As previously described in Part II, Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 29, 2024, management is in the process of implementing its remediation plan. The Company is committed to remediating the material weaknesses identified above, fostering continuous improvement in internal controls and enhancing its overall internal control environment. Since identifying the above material weaknesses, the Company has begun the process of implementing the remediation activities described below. The Company believes that these activities, when fully implemented, should remediate the identified material weaknesses and strengthen its internal control over financial reporting. These remediation efforts remain ongoing, and additional remediation initiatives may be necessary.
Accordingly, as management continues to monitor the effectiveness of our internal control over financial reporting, the Company will continue to perform additional procedures prescribed by management, including the use of certain manual mitigating control procedures and the employment of additional tools and resources deemed necessary, to ensure that our future consolidated financial statements are fairly stated in all material respects. The following planned remediation activities highlight the Company’s commitment to remediating the identified material weaknesses:
| ● | Hire finance and accounting professionals with the appropriate level of experience and training necessary to develop, maintain and improve our accounting policies, procedures and internal controls, utilize third-party consultants and internal audit professionals to enhance the control environment, and continue to hire other qualified finance and accounting professionals. |
| ● | Provide, and continue to provide, training for employees regarding their responsibilities related to the performance or oversight of internal controls. |
| ● | Reinforce the importance of communication between the operations, accounting, and legal departments regarding key terms of, and changes or modifications to, customer, debt, equity, legal and other contracts by establishing controls requiring finance department approval of certain non-standard terms and agreements. |
| ● | Begin the implementation of a process to reevaluate, revise and improve our Sarbanes-Oxley compliance program, including governance, risk assessment, testing methodologies and corrective action. The Company plans to enhance our risk assessment procedures and conduct a comprehensive risk assessment. |
| ● | Develop, and continue to develop, internal control documentation over financial processes and related disclosures. The Company plans to continue to design and implement control activities to mitigate risks identified and test the operating effectiveness of such controls. |
If we are not able to maintain effective internal control over financial reporting and Disclosure Controls, or if material weaknesses are discovered in future periods, a risk that is significantly increased in light of the complexity of our business, we may be unable to accurately and timely report our financial position, results of operations, cash flows or key operating metrics, which could result in late filings of the annual and quarterly reports under the Exchange Act, restatements of financial statements or other corrective disclosures, an inability to access commercial lending markets, defaults under its credit facilities and other agreements, or other material adverse effects on our business, reputation, results of operations, financial condition or liquidity.
The material weaknesses will not be considered remediated, however, until the applicable controls operate for a sufficient period of time, and management has concluded, through testing, that these controls are operating effectively.
Changes in internal control over financial reporting
Through the thirty-nine week period ended September 28, 2025, we integrated the internal control systems of SunPower Acquisition which we acquired in the fourth quarter of our prior fiscal year. This integration included the alignment of revenue recognition and expenses, consolidation, financial reporting and IT system controls.
Other than the remediation efforts described above, there were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) that have occurred during the thirty-nine week period ended September 28, 2025, that have materially impacted, or are reasonably likely to materially impact, our internal control over financial reporting.
Limitations on effectiveness of controls and procedures
We do not expect that our Disclosure Controls will prevent all errors and all instances of fraud. Disclosure Controls, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the Disclosure Controls are met. Further, the design of Disclosure Controls must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all Disclosure Controls, no evaluation of Disclosure Controls can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of Disclosure Controls also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

On December 4, 2025, the Company entered into a Settlement Agreement with Siemens Government Technologies, Inc. and Siemens Industry, Inc. to resolve a case in the Circuit Court of Fairfax County, Virginia and other related cases as well as to resolve potential claims related to Siemens’ Atwater Wastewater Treatment Plant. In exchange for full releases, the Company agreed to pay Siemens $9.5 million spread across four payments to be made at the end of each calendar quarter during fiscal 2026. If the Company successfully engages in any form of new financing or new debt worth $1.0 million or more, or successfully obtains shareholder approval for the issuance of additional shares in connection with the raise of additional funds and/or any merger or acquisition activity, the next due quarterly payment to Siemens (if any) becomes immediately due and payable. The settlement payment to Siemens is secured by a first-priority continuing security interest in $9.5 million of Company collateral. This security interest is reduced on a one-to-one basis as the settlement payments are made.

(a) Description of business
SunPower Inc. and Subsidiaries (“SunPower” or the “Company”) is the rebranded name of Complete Solaria, Inc. (“Complete Solaria”). The rebranding was effective April 22, 2025. References to the Company and SunPower include the same entity under its previous name of Complete Solaria.
The Company originally incorporated in Delaware under the name Complete Solaria, Inc. and is a residential solar installer that offers storage and home energy solutions to customers in North America. The Company was formed through Complete Solar Holding Corporation’s acquisition of The Solaria Corporation (“Solaria”). The Company is headquartered in Orem, Utah.
Complete Solar, Inc. (“Complete Solar”) was incorporated in Delaware on February 22, 2010. Through February 2022, the Company operated as Complete Solar, Inc., a single legal entity. 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. Subsequently, Complete Solar Holdings changed its name to Complete Solaria, Inc.
On July 18, 2023, the Company consummated a series of merger transactions contemplated by an Amended and Restated Business Combination Agreement entered into with wholly-owned subsidiaries of Freedom Acquisition I Corp. (“FACT”) (“Mergers”), equating to a reverse recapitalization for accounting purposes. Under the reverse recapitalization of accounting, FACT was treated as the acquired company for financial statement reporting purposes. This determination was based on the Company having a majority of the voting power of the post-combination company, the Company’s senior management comprising substantially all of the senior management of the post-combination company, and the Company’s operations comprising the ongoing operations of the post-combination company. Accordingly, for accounting purposes, the Mergers were treated as the equivalent of a capital transaction in which Complete Solaria issued stock for the net assets of FACT. The net assets of FACT were stated at historical cost, with no goodwill or other intangible assets recorded.
On August 5, 2024, Complete Solaria entered into an Asset Purchase Agreement (the “APA”) among Complete Solaria, SunPower Corporation and SunPower Corporation’s direct and indirect subsidiaries (collectively, the “SunPower Debtors”) providing for the Company’s purchase of certain assets relating to the Blue Raven Solar business, New Homes Business and Non-Installing Dealer network previously operated by the SunPower Debtors (“SunPower Acquisition”). The APA was entered into in connection with a voluntary petition filed by SunPower Corporation under Chapter 11 of the United States Code, 11 U.S.C.§§ 101-1532. The SunPower Acquisition was approved on September 23, 2024, by the United States Bankruptcy Court for the District of Delaware. The Company completed the acquisition in the Company’s fiscal fourth quarter on September 30, 2024.
On September 21, 2025, Complete Solaria, Inc., and Complete Solar, Inc, a subsidiary of the Company, entered into a Membership Interest Purchase Agreement (“MIPA”) with Sunder Energy LLC (“Sunder”) and the seller, Chicken Parm Pizza LLC (“Seller/Member”), the sole member of Sunder. The acquisition of Sunder was completed on September 24, 2025, and the financial results of Sunder have been included in the Company’s unaudited condensed consolidated financial statements since the date of acquisition. Refer to Note 3 – Business Combinations for a description of Sunder.
The aforementioned acquisitions were accounted for as business combinations in accordance with ASC 805, Business Combinations as more fully described in Note 3 – Business Combinations.
The Company completed its legal renaming to SunPower Inc. in the period ended September 28, 2025. (b) Liquidity and going concern
Since inception through September 28, 2025, the Company has incurred recurring losses and negative cash flows from operations. The Company’s loss from continuing operations was $30.1 million for the thirty-nine-week period ended September 28, 2025. As of that date, the Company had an accumulated deficit of $442.6 million, total debt of $204.3 million, and cash and cash equivalents, excluding restricted cash, of $5.1 million. The Company anticipates that operating losses and negative operating cash flows may continue in the near term, which raises substantial doubt about its ability to continue as a going concern.
Management is actively pursuing plans to mitigate these conditions, including obtaining additional capital resources through equity or debt financing and leveraging support from significant shareholders when necessary. Historically, the Company has raised funds through private placements of equity securities, issuance of convertible notes and debt, and proceeds from mergers. During the year, funding from significant shareholders, has supported working capital requirements, and similar measures may be considered in the upcoming periods.
Management plans to proactively position the Company to access capital markets once eligible and pursue strategic opportunities to strengthen liquidity. Given the one-year eligibility requirement for Form S-3 after regaining current filer status, the Company will focus on alternative financing options to maintain flexibility and efficiency in capital raising.
However, there can be no assurance that these plans will be successful or that financing will be available on favorable terms. If adequate funding cannot be secured, the Company may need to reevaluate its operating plan, which could include reducing expenditure, extending payment terms with suppliers, liquidating assets, or suspending certain programs.
Therefore, there is substantial doubt about the Company’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 Accounting Policies | (2) Summary of Significant Accounting Policies
(a) Basis of presentation
The interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
The accompanying interim condensed consolidated financial statements are unaudited and have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim unaudited condensed consolidated financial statements do not include all the information and disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, these interim unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s financial position as of September 28, 2025, and the results of operations for the thirteen and thirty-nine week periods ended September 28, 2025 and September 29, 2024. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year or any other future period. These interim unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended December 29, 2024, included in the Company’s Annual Report on Form 10-K filed with the SEC on April 30, 2025.
The Company’s operates on a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. The Company’s fiscal year for 2024 ended December 29, 2024. The Company’s third fiscal quarters for 2025 and 2024 in this report on Form 10-Q ended on September 28, 2025 (“Third Quarter 2025”) and September 29, 2024 (“Third Quarter 2024”), respectively. (b) Cash and cash equivalents and restricted cash
The Company reconciles cash, cash equivalents, and restricted cash reported in its unaudited condensed consolidated balance sheets that aggregate to the beginning and ending balances shown in the Company’s unaudited condensed consolidated statements of cash flows as follows (in thousands):
(c) Estimated credit losses
The Company recognizes an allowance for credit losses at the time a receivable is recorded based on the Company’s estimate of expected credit losses, historical write-off experience, and current account knowledge, and adjusts this estimate over the life of the receivable as needed. The Company evaluates the aggregation and risk characteristics of a receivable pool and develops loss rates that reflect historical collections over the time horizon that the Company is exposed to credit risk, and payment terms or conditions that may materially affect future forecasts.
The Company performs ongoing credit evaluations of its customers’ financial condition when deemed necessary. The Company maintains an allowance for credit losses based on the expected collectability of all accounts receivable, which takes into consideration an analysis of historical bad debts, specific customer creditworthiness and current economic trends. The Company believes that its concentration of credit risk is limited because of the large number of customers, credit quality of the customer base, small account balances for most of these customers, and customer geographic diversification. The Company does not have any off-balance sheet credit exposure relating to its customers.
The following table summarizes the allowance for credit loss activity as of and for the periods ended (in thousands):
(d) Contract liabilities
Contract liabilities consist of deferred revenue and customer advances, which represent consideration received from a customer prior to transferring control of goods or services to the customer under the terms of a sales contract. Total contract liabilities balances as of the respective dates are as follows (in thousands):
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 payment, or when such payment 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 this deferred revenue as a contract liability. Most installation projects are completed within 12-months. As such, a significant portion of the Company’s contract liabilities is reflected within current liabilities in the accompanying condensed consolidated balance sheets. Contract liabilities for installation projects expected to be completed beyond 12 months are classified as noncurrent obligations in the accompanying condensed consolidated balance sheets.
(e) Revenue recognition
Revenue is recognized for Residential Solar Installation and New Homes Business when a customer obtains control of promised products and services and the Company has satisfied its performance obligations which is the date by which substantially all of its design and installation is complete for a fully functioning solar power system to interconnect to the local power grid.
Installation includes the design of a solar energy system, the delivery of the components of the solar energy system (i.e., photovoltaic system, inverter, battery storage, etc.), installation services and services facilitating the connection of the solar energy system to the power grid. The Company accounts for these services as inputs to a combined output, resulting in a single service-based performance obligation.
The amount of revenue recognized reflects the consideration which the Company expects to be entitled to receive in exchange for the products and services. To achieve this core principle, the Company applies the following five steps:
Step 1. Identification of the contract(s) with a customer;
Step 2. Identification of the performance obligations in the contracts(s);
Step 3. Determination of the transaction price;
Step 4. Allocation of the transaction price to the performance obligations;
Step 5. Recognition of the revenue when, or as, the Company satisfies a performance obligation.
Residential Solar Installation revenues
The Company’s Residential Solar Installation segment sells products through a network of installing and non-installing dealers and resellers, as well as its internal sales team. The Company’s contracts with customers include three primary contract types:
New Homes Business revenues
The Company’s New Homes Business segment sells through a network of home builders as well as its internal sales team. The Company’s contracts with customers include two primary contract types:
The Company’s performance obligation for both of these reportable segments is to design and install a fully functioning solar energy system. For all contract types (with the exception of New Homes Business Lease agreements), the Company recognizes revenue over time. The Company’s over-time revenue recognition begins when the solar power system is fully installed (as it is at this point that control of the asset begins to be transferred to the customer, and the customer retains the significant risks and rewards of ownership of the solar power system). The Company recognizes revenue using the input method based on direct costs to install the system and defers the costs of installation until such time that control of the asset transfers to the customer (installation). For New Homes Business Lease agreements, the Company considers the performance obligation to be satisfied at a point in time upon acceptance of the system by the customer.
Revenue is generally recognized at the transaction price contained within the agreement, net of the costs of financing, or other consideration paid to the customers that is not in exchange for a distinct good or service. The Company’s arrangements may contain clauses that can either increase or decrease the transaction price. Variable consideration is estimated at each measurement date at its most likely amount to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur and true-ups are applied prospectively as such estimates change.
The Company records deferred revenue for amounts invoiced that are received in advance of the provisioning of services. In certain contracts with customers, the Company arranges for a third-party financing partner to provide financing to the customer. The Company collects upfront from the financing partner and the customer will provide instalment payments to the financing partner. The Company records revenue in the amount received from the financing partner, net of any financing fees charged to the homeowner, which the Company considers to be a customer incentive. None of the Company’s contracts contain a significant financing component.
Sunder
The Company earns revenue from contracts sold to customers for solar installations performed by third-party installation companies. The Company recognizes revenue at a point in time when Permission to Operate (“PTO”) is complete. The Company acts as an agent in these arrangements and records revenue on a net basis. The Company does not have significant financing components in its contracts. The Company does not provide warranty services and does not record a warranty reserve.
Costs to obtain and fulfill contracts
The Company’s costs to obtain and fulfill contracts, when recognized, associated with systems sales are expensed as sales commission and cost of revenue, respectively. In addition, incentives the Company provides to its customers, such as discounts and rebates, are recorded net to the revenue the Company has recognized on the solar power system. Disaggregation of revenue
Refer to the table below for the Company’s revenue recognized (in thousands):
All revenue was generated in the United States.
Remaining performance obligations
The Company elected the practical expedient not to disclose the remaining performance obligations for contracts that are less than one year in length.
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 expenses 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 September 28, 2025 and December 29, 2024, deferred commissions were not material.
(f) Prepaid expenses and other current assets
The following table summarizes the components of prepaid expenses and other current assets:
(g) Recent accounting pronouncements
Accounting pronouncements adopted
In July 2025, the FASB issued ASU 2025-05 “Measurement of Credit Losses for Accounts Receivable and Contract Assets” which provides an update to all entities with a practical expedient when estimating expected credit losses. This ASU is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. The Company adopted ASU 2025-05 in the thirteen week period ended September 28, 2025. The impact of the adoption was not material to the condensed consolidated financial statements. Accounting pronouncements not yet adopted
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 will adopt this ASU in its annual report for the fiscal year ending December 28, 2025. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires the disaggregation of certain expenses in the notes of the financial statements to provide enhanced transparency into the expense captions presented on the face of the income statement. The FASB subsequently issued ASU 2025-01 “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date”, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in ASU 2024-03 in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
In November 2024, the FASB issued ASU No. 2024-04, Debt-Debt with Conversion and Other Options (Subtopic 470-20) (“ASU 2024-04”). The guidance in ASU 2024-04 clarifies the requirements related to accounting for the settlement of a debt instrument as an induced conversion. The standard is effective for fiscal years beginning after December 15, 2025, and interim periods within fiscal years beginning after December 15, 2025, with early adoption permitted as of the beginning of a reporting period if the entity has also adopted ASU 2020-06 for that period. The Company is currently evaluating the impact that the adoption of ASU 2024-04 may have on its consolidated financial statements.
In March 2024, the FASB issued ASU 2024-02 “Codification Improvements-Amendments to Remove References to the Concepts Statements”, which removes various references to concepts statements from the FASB Accounting Standards Codification. This ASU is effective for the Company beginning in the first quarter of fiscal year 2026, with early adoption permitted. The Company expects the new guidance will have an immaterial impact on its consolidated financial statements and intends to adopt the guidance when it becomes effective in the first quarter of fiscal year 2026.
In September 2025, the FASB issued ASU 2025-06 “Targeted improvements to the Accounting for Internal-Use Software” which is an update to remove all references to prescriptive and sequential software development stages (referred to as “project stages”). This ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact that the adoption of ASU 2025-06 may have on its consolidated financial statements.
(h) Changes in related parties
Transactions with CRSEF Solis Holdings, LLC and its affiliates (“Carlyle”), have been disclosed as related party transactions until it ceased being a significant shareholder in the Company.

| Business Combinations | (3) Business Combinations
SunPower Acquisition
On September 30, 2024, commencing the Company’s fourth quarter of fiscal 2024, the Company completed the acquisition of certain assets and assumption of certain liabilities from SunPower Debtors for an aggregate cash consideration paid of $54.5 million, net of $1.0 million of cash acquired. Prior to its declaration of bankruptcy SunPower Debtors was a solar technology and energy services provider that offered fully integrated solar, storage, and home energy solutions to customers in the United States through an array of hardware, software, and “Smart Energy” solutions. The financial results of the SunPower Acquisition have been included in the Company’s unaudited condensed consolidated financial statements since the date of the SunPower Acquisition. This transaction was accounted for as a business combination in accordance with ASC 805, Business Combinations.
Transaction costs incurred in connection with the close of the SunPower Acquisition totaled $7.2 million and were expensed by the Company and included in general and administrative expenses within the fourth quarter of the Company’s fiscal year ended December 29, 2024.
The fair values of assets acquired and liabilities assumed were based upon a preliminary valuation. Consistent with previous disclosures, the Company disclosed that further adjustments to the Company’s inventory were expected in the thirty-nine week period ended September 28, 2025. As of September 28, 2025, the Company finalized the fair value of the assets acquired and liabilities assumed. The inventory acquired related to 1) work-in-progress at various stages of completion as of the acquisition date for which further analysis was required in order to determine which systems could be sold to a financing partner (for which the remaining units determined to be sellable to that partner were resolved during the thirteen-weeks ended September 28, 2025) and 2) completed systems that were acquired as of the acquisition date for which uncertainty existed due to unsettled matters with the SunPower Bankruptcy Estate (which were resolved in connection with the Company’s settlement with the SunPower Bankruptcy Estate). The final determination of the fair values of the inventory and intangibles upon settlement of these matters resulted in a revision to the inventory and intangibles with the offsetting adjustment to goodwill during the measurement period. The Company concluded that the finalization of the measurement period adjustment resulted in the recognition of $2.2 million of costs of goods in the thirteen week period ended September 28, 2025 that would have been recognized in the thirteen week period ended June 29, 2025 (which the Company concluded was not material to the financial statements for the thirteen- and thirty-nine week periods ended September 28, 2025).
The following table summarizes the provisional and final fair values of identifiable assets acquired and liabilities assumed and measurement period adjustments (in thousands):
Sunder Energy LLC Acquisition
On September 24, 2025 (“Closing”), the Company completed the acquisition of all assets and assumption of all liabilities of the Membership Interests of Sunder for aggregate consideration of $57.8 million. Sunder is a solar sales company. The Company acquired Sunder as a strategic acquisition to expand its overall market share and its penetration into more U.S. states. Per the terms of the MIPA, the Company acquired all of the outstanding membership interest of Sunder for (1) $20.7 million in cash, subject to certain working capital and other adjustments; (2) a promissory note to the Member in the principal amount of $20.0 million (“Seller Note”); (3) and 10.0 million shares of the Company’s common stock (valued at the closing share price on September 24, 2025, of $1.71 per share), consisting of (i) 3,333,334 shares of the Company’s common stock and (ii) subject to approval of such issuances by the Company’s stockholders, (x) an additional 3,333,333 shares of the Company’s common stock to be issued on the 12-month anniversary of the Closing and (y) a further 3,333,333 shares of the Company’s common stock to be issued on the 18-month anniversary of the Closing (“Deferred Consideration Shares”). In lieu of issuing the Deferred Consideration Shares, the Company, in its sole discretion, may elect to pay the Member a cash payment equal to the number of Deferred Consideration Shares otherwise issuable by the Company multiplied by the volume-weighted average price of the Company’s common stock as quoted on Nasdaq for the 30-trading day period ending two business days prior to the date on which the applicable Deferred Consideration Shares were otherwise issuable (“Cash in Lieu Amount”). If the Company elects to pay the Cash in Lieu Amount, 50% of the Cash in Lieu Amount will be paid on the three-month anniversary of the date on which the applicable Deferred Consideration Shares were otherwise issuable, with the remaining 50% of the Cash in Lieu Amount payable on the 6 month anniversary of the date on which the applicable Deferred Consideration Shares were otherwise issuable. The shares of the Company’s common stock were valued at $17.1 million at the date of acquisition. The deferred consideration paid and payable in connection with the Sunder acquisition was accounted for on the Company’s balance sheet as of September 28, 2025, as (i) $5.7 million within Additional paid-in capital, (ii) $5.7 million within Accrued expenses and other current liabilities, and (iii) $5.7 million within Other long-term liabilities.
The total consideration is summarized as follows (in thousands):
The fair values of assets acquired and liabilities assumed were based upon a preliminary valuation, and the Company’s estimates and assumptions are subject to change within the measurement period. Due to the timing of the acquisition at the end of the September 28, 2025 quarterly period, the purchase price accounting remains open for the components of working capital, identification and valuation of intangibles and allocation of goodwill to reportable segments. The Company has elected the practical expedient within ASC 805-20-30-27 through 805-20-30-30 to recognize and measure contract liabilities in accordance with ASC 606 – Revenue from Contracts with Customers as if it had originated the acquired contract. Thus, the amount of any contract liabilities immediately prior to the acquisition will be the comparable amounts recognized in the determination of assets acquired and liabilities assumed by the Company.
The following table summarizes the provisional fair value of identifiable assets acquired and liabilities assumed (in thousands):
As of the date of acquisition the intangible assets acquired and estimated useful lives were as follows:
Goodwill represents the excess of the preliminary estimated consideration transferred over the fair value of the net tangible and intangible assets acquired that is associated with the excess cash flows that the acquisition is expected to generate in the future. The goodwill is tax deductible. The Sunder acquisition contributed $4.3 million in revenue and $0.3 million of income before income taxes for the period from the acquisition date to September 28, 2025.
Unaudited pro forma financial information
The following presents the unaudited pro forma consolidated financial information of the Company for the periods presented, as if the SunPower Acquisition and Sunder had been acquired as of January 1, 2024.
The unaudited pro forma combined financial information does not give effect to any cost savings, operating synergies or revenue synergies that may result from the acquisition of SunPower Acquisition or Sunder. The pro forma results do not necessarily reflect the actual results of operations of the combined business (in thousands).

Common stock purchase agreement
On July 16, 2024, the Company entered into a common stock purchase agreement with White Lion Capital, LLC (“White Lion”), as amended on July 24, 2024 (“White Lion SPA”), and a related registration rights agreement for an equity line of credit financing facility. Pursuant to the White Lion SPA, the Company has the right, but not the obligation, to require White Lion to purchase, from time to time, up to $30 million in aggregate gross purchase price of newly issued shares of the Company’s common stock, subject to the caps and certain limitations and conditions set forth in the White Lion SPA, including terms that restrict the ability of the Company to issue shares of common stock to White Lion that would result in White Lion beneficially owning more than 9.99% of the Company’s outstanding common stock.
On August 14, 2024, the Company entered into Amendment No. 2 to the White Lion SPA (collectively with the White Lion SPA “White Lion Amended SPA”). The White Lion Amended SPA provides that the Company may notify White Lion to exercise the Company’s right to sell shares of its common stock by delivering an Hour Rapid Purchase Notice. If the Company delivers an Hour Rapid Purchase Notice, the Company shall deliver to White Lion shares of common stock not to exceed the lesser of (i) five percent of the Average Daily Trading Volume on the date of an Hour Rapid Purchase Notice and (ii) 100,000 shares of common stock. The closing of the transactions under an Hour Rapid Purchase Notice will occur one Business Day following the date on which the Hour Rapid Purchase Notice is delivered. At such closing, White Lion will pay the Company the Hour Rapid Purchase Investment Amount equal to the number of shares of common stock subject to the applicable Hour Rapid Purchase Notice multiplied by the lowest traded price of the Company’s common stock during the one-hour period following White Lion’s consent to the acceptance of the applicable Hour Rapid Purchase Notice.
Under the White Lion Amended SPA, the Company issued 1.0 million and 2.9 million shares of the Company’s common stock for proceeds of $1.7 million and $6.7 million in the thirty-nine week period ended September 28, 2025 and fiscal year ended December 29, 2024, respectively. The Company has reserved shares of common stock for issuance related to the following:
Warrants
The potential number of shares of the Company’s common stock for outstanding warrants were as follows:
Ayna warrant
On June 17, 2024, a warrant to purchase 6,000,000 shares of the Company’s common stock (“Ayna Warrant”) was issued to Ayna.AI LLC (“Ayna”) at an exercise price per share of $0.01, subject to the provisions and upon the terms and conditions set forth in the Ayna Warrant. At issuance, the fair value of the Ayna Warrant was determined to be $9.2 million, based on the intrinsic value of the Ayna Warrant and the $0.01 per share exercise price. The Ayna Warrant was set to expire on June 17, 2029. The issuance of the Ayna Warrant by the Company was in satisfaction of the compensation for services provided to the Company by Ayna under the terms of a statement of work (“Ayna SOW”), signed May 21, 2024 (and effective as of March 12, 2024), as incorporated into a master services agreement dated March 12, 2024. Under the Ayna SOW, Ayna provided services in connection with the anticipated return of the Company to cash-flow positive performance.
The Ayna Warrant was accounted for under ASC 718 Compensation – Stock Compensation as it met the conditions for equity classification and therefore, the Ayna Warrant was not subsequently remeasured in future periods. The Company recognized expense of $3.8 million and $5.4 million in the thirteen and thirty-nine week periods ended September 29, 2024, respectively.
The Ayna Warrant became fully exercisable for the 6,000,000 shares of the Company’s common stock on September 9, 2024. The Ayna Warrant was exercised in full for cash of $0.06 million in January 2025.
Cantor warrant
In July 2024, the Company issued a warrant (“Cantor Warrant”) to a third-party service provider to purchase 3,066,141 shares of the Company’s common stock in exchange for services provided in the issuance of the July 2024 Notes (refer to Note 9 – Borrowings and Derivative Liabilities). The Cantor Warrant was immediately exercisable at a price of $1.68 per share and has an expiration date in July 2029. At issuance, the fair value of the Cantor Warrant was determined to be $1.4 million, of which $0.9 million was recorded as a debt discount and $0.5 million was attributable to the convertible notes issued in the Exchange Agreement (as defined in Note 9 – Borrowings and Derivative Liabilities) and reduced the gain on the troubled debt restructuring recognized in the Company’s annual consolidated statement of operations and comprehensive loss for fiscal 2024 as described in Note 9 – Borrowings and Derivative Liabilities. The fair value of the Cantor Warrant was derived using the Black-Scholes model with the following assumptions: expected volatility of 55%; risk-free interest rate of 4.2%; expected term of 5 years; and no dividend yield. The fair value of this warrant was recorded within additional paid-in capital on the Company’s unaudited condensed consolidated balance sheets and has not been subsequently remeasured in future periods as it met the conditions for equity classification.
Carlyle warrant
In February 2022, as part of a debt financing arrangement with Carlyle , the Company issued Carlyle a warrant to purchase 2,886,952 shares of Legacy Complete Solaria Common Stock at a price per share of $0.01. The warrant contained two tranches, the first of which was immediately exercisable for 1,995,879 shares of common stock. The second tranche expired on December 31, 2022, prior to becoming exercisable. In December 2023, Carlyle was issued a warrant to purchase an additional 2,190,604 shares of the Company’s common stock related to an anti-dilution provision under the then-existing debt arrangement with Carlyle.
In July 2023, and in connection with the closing of the Mergers, the Company entered into the Carlyle Warrant Amendment (as defined in Note 9 – Borrowings and Derivative Liabilities), 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. The Carlyle Warrant Amendment required the Company to issue to 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 was inclusive of the outstanding warrant to purchase 1,995,879 shares at the time of modification. The warrant, which expires on July 18, 2030, provided 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 was ten (10) days after the date of the agreement, an additional 350,000 shares; plus (c) on and after the date that was thirty (30) days after the date of the agreement, if the original investment amount had not been repaid, an additional 150,000 shares; plus (d) on and after the date that was ninety (90) days after the date of the agreement, if the original investment amount had 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 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 Derivatives and Hedging and ASC 718, Compensation – Stock Compensation. The change in the fair value of the liability classified Carlyle Warrant through June 30, 2024, was recorded within Other expense, net in the accompanying condensed consolidated statements of operations and comprehensive loss. The change in the fair value of the Carlyle Warrant resulted in income of $2.9 million in the twenty-six week period ended June 30, 2024.
On July 1, 2024, in connection with the Exchange Agreement, the Carlyle Warrant was modified, and the modification fixed the number of shares of the Company’s common stock that may be issued upon exercise of the Carlyle Warrant at 4,936,483. At the July 1, 2024, modification date, the Carlyle Warrant had a fair value of $7.3 million compared to its fair value of $6.6 million on June 30, 2024. The Company recognized this $0.7 million of expense related to the remeasurement of the Carlyle Warrant liability to its fair value within “Gain on Extinguishment of Debt” within the Company’s consolidated statement of operations and comprehensive loss in its fiscal 2024 consolidated results. The modification of the Carlyle Warrant also resulted in the reclassification of the Carlyle Warrant from liability to equity classification, resulting in an increase to additional paid-in capital of $7.3 million and a reduction in the warrant liability of $7.3 million.
Carlyle exercised the warrant for shares of the Company’s common stock in the fourth quarter of fiscal 2024. |

Note payable to Seller – related party
On September 24, 2025, the Company issued a note payable to the sellers of Sunder (“Seller Note”) to the Seller/Member in connection with the acquisition of 100% of the membership interests in Sunder. The Seller Note has an original principal amount of $20.0 million. The Seller Note bears interest at 7.0% per annum, compounded at the end of each calendar quarter. Interest is due and payable concurrent with the payment of the principal balance. The maturity date under the Seller Note is the earlier of (i) May 15, 2026 and (ii) the date on which all amounts under the Seller Note otherwise become due and payable following an event of default. The Seller Note must also be repaid in the event of a change of control of the Company or the sale of all or substantially all of the consolidated assets of the Company and its subsidiaries. The Seller Note includes customary events of default, including: (a) the Company’s failure to pay the Seller Note when due, (b) the Company’s voluntary or involuntary bankruptcy, (c) the Company’s liquidation or dissolution, (d) a change of control of the Company, (e) the Company’s material breach of the covenants applicable to the Company under the Seller Note, subject to applicable cure periods, and (f) if any of the Company’s representations or warranties made in the Seller Note were untrue in any material respect when made. The Company concluded that since the sellers joined the Company and have a level of influence that is not insignificant, they are related parties of the Company and therefore the Seller Note is a related party obligation. Management concluded that the carrying value of the Seller Note approximates its fair value due to the short-term nature of the obligation. Interest expense recognized on the Seller Note was less than $0.1 million in the thirteen and thirty-nine week periods ended September 28, 2025. Exchange Agreement

| SAFE Agreements | (10) SAFE Agreements
First SAFE
On January 31, 2024, the Company entered into a Simple Agreement for Future Equity (“SAFE”) (the “First SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (the “Purchaser”), a related party, affiliated with Thurman J. Rodgers, the Company’s Chief Executive Officer and a director, in connection with the Purchaser investing $1.5 million in the Company. The First SAFE did not accrue interest. The First SAFE was initially convertible into shares of the Company’s common stock, par value $0.0001 per share, upon the 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 (“First SAFE Amendment”) that converted the First SAFE investment of $1.5 million into 4,166,667 shares of the Company’s common stock based on a conversion price of $0.36 per share, defined in the First SAFE Amendment as the product of (i) $0.45, the closing price of the Company’s common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, the Company recorded a debit to the First SAFE Agreement of $1.5 million, a credit to Additional paid-in-capital of $1.9 million and recognized expense of $0.4 million within Other expense, net in its unaudited condensed consolidated statement of operations in the Company’s second fiscal quarter ended June 30, 2024.
Second SAFE
On February 15, 2024, the Company entered into a second SAFE (the “Second SAFE”) with the Purchaser, in connection with the Purchaser investing $3.5 million in the Company. The Second SAFE did not accrue interest. The Second SAFE was initially convertible into shares of the Company’s common stock upon the initial closing of an Equity Financing transaction at a per share conversion price which was equal to the lower of (i) the Second SAFE Price, and (ii) 80% of the price per share of the Company’s common stock sold in an Equity Financing transaction. 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 the Company’s 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 (“Second SAFE Amendment”) that converted the Second SAFE investment of $3.5 million into 9,722,222 shares of the Company’s common stock based on a conversion price of $0.36 per share, defined in the Second SAFE Amendment as the product of (i) $0.45, the closing price of the Company’s common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, the Company recorded a debit to the Second SAFE Agreement of $3.5 million, a credit to Additional paid-in-capital of $4.4 million and recognized expense of $0.9 million within Other expense, net in its unaudited condensed consolidated statement of operations in the Company’s second fiscal quarter ended June 30, 2024. Third SAFE
On May 13, 2024, the Company entered into a third SAFE (the “Third SAFE”) with the Purchaser, in connection with the Purchaser investing $1.0 million in the Company. The Third SAFE is convertible into shares of the Company’s common stock 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 issues and sells shares of its common stock in an Equity Financing transaction, at a per share conversion price which is equal to 50% of the price per share of the Company’s common stock sold in an Equity Financing. If the Company consummates a change of control prior to the termination of the Third SAFE, the Purchaser will be automatically entitled to receive a portion of the proceeds of such liquidity event equal to $1.0 million, subject to certain adjustments as set forth in the Third SAFE. The Third SAFE is convertible into a maximum of 2,750,000 shares of the Company’s common stock, assuming a per share conversion price of $0.275, which is the product of (i) $0.55, the closing price of the Company’s common stock on May 13, 2024, multiplied by (ii) 50%. Given that the Third SAFE may be settled in cash or a variable number of shares, the Company has accounted for the instrument as a liability at its fair value.
The estimated fair value of the Third SAFE was $0.5 million and $0.4 million as of September 28, 2025 and December 29, 2024, based upon the assumptions disclosed in Note 4 – Fair Value Measurements.
The change in the fair value of the Third SAFE is recorded within Other expense, net in the accompanying condensed consolidated statements of operations and comprehensive loss. The change in the fair value of the Third SAFE was expense of $0.1 million and $0.9 million in the thirteen week periods ended September 28, 2025 and September 29, 2024, respectively. The change in the fair value of the Third SAFE was expense of $0.1 million and $0.9 million in the thirty-nine week periods ended September 28, 2025 and September 29, 2024, respectively. |

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 SunPower common stock may be issued under the 2023 Plan. In addition, the number of shares of SunPower 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 SunPower’s common stock outstanding on December 31 of the preceding year, or (2) a lesser number of shares of SunPower common stock determined by SunPower’s Board prior to the date of the increase. The maximum number of shares of SunPower 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”).

Warranty provision
Activity by period relating to the Company’s warranty provision was as follows (in thousands):
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 would not have a material adverse effect on the business, financial position, results of operations, or cash flows of the Company.
Settlement of dispute with SunPower Debtors Bankruptcy Estate
Following the consummation of the acquisition of certain assets and assumption of certain liabilities of SunPower Debtors on September 30, 2024, certain matters pertaining to the acquisition were under dispute which included 1) amounts owed to and from the buyer and seller with respect to amounts in escrow related to the consideration transferred, 2) the right to the cash acquired in the acquisition, and 3) the right for the Company to sell and collect for certain solar systems that were acquired as a part of the acquisition that were sold or are to be sold to homebuilders within the New Homes Business. On June 25, 2025, all matters under dispute were resolved by the Company and the SunPower Bankruptcy Estate. Matters 1) and 2) were resolved such that no amounts will be paid (or received) by the Company. Matter 3) was resolved such that the Company has the right to sell the related inventory acquired and collect the underlying sales price for the sale of the solar system. In connection with each system sold, the Company is required to remit a portion of the sales price to the SunPower Bankruptcy Estate. The impact of the related settlement is not anticipated to be material.
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 the Company’s business, financial position, results of operations, or cash flows. The Company has a loss contingency for legal settlements of $9.2 million and $7.7 million recorded within accrued expenses and other current liabilities in its unaudited condensed consolidated balance sheets at each of September 28, 2025 and December 29, 2024. 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’s 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, Solaria filed a Notice of Withdrawal of Appeal and will not appeal the Court’s Preliminary Injunction Order. Between August 2023 and March 2024, the parties were engaged in discovery negotiations and the Company produced documents to SolarPark. The Company produced its last set of documents on March 14, 2024. On August 14, 2025, the Court held a virtual hearing and revived the case. SolarPark subsequently amended the complaint, and the Company responded on October 14, 2025, with a motion to dismiss the complaint in its entirety. The Company also believes it has valid counterclaims to pursue against SolarPark. The litigation remains ongoing.
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 Government Technologies, Inc. (“Siemens Government Technologies”) filed a lawsuit against Solaria Corporation in Fairfax Circuit Court (the “Court”) in Fairfax, Virginia. On July 27, 2023, Siemens Government Technologies moved to amend the complaint to add Siemens Industry Inc. as a co-plaintiff. This motion was granted on August 25, 2023. On October 23, 2023, Siemens Government Technologies and Siemens Industry Inc. (collectively, “Siemens”) and Solaria Corporation stipulated to add Solar CA, LLC as a co-defendant. Solaria Corporation and Solar CA, LLC (collectively, the “Subsidiaries”) are both wholly-owned subsidiaries of the Company. In the lawsuit, Siemens alleged that the Subsidiaries breached express and implied warranties under a purchase order that Siemens placed with the Subsidiaries for a solar module system. Siemens claimed damages of approximately $6.9 million, inclusive of amounts of the Subsidiaries’ indemnity obligations to Siemens, plus attorneys’ fees. On February 22, 2024, the Court issued an order against the Subsidiaries which awarded Siemens approximately $6.9 million, inclusive of the amounts of the Subsidiaries’ indemnity obligations to Siemens, plus attorneys’ fees, the amount of which would 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-and post-judgment interest. The Company opposed Siemens’ motion for attorneys’ fees, expenses, and pre- and post-judgment interest on April 5, 2024. On June 17, 2024, the Court entered a final order which awarded Siemens a total of $2.0 million in attorneys’ fees and costs. The Company has appealed these judgments.
In addition to the above, on August 19, 2024, Siemens applied for the enforcement to a sister state judgment in the Superior Court of Alameda, California and the court entered a judgement in favor of Siemens. On December 9, 2024, Siemens moved to amend the judgment to add the Company as a judgement debtor. The Subsidiaries opposed the Siemens motion. On June 30, 2025, the California court found that the Company should be added as a judgment debtor party in California. In addition, the parties argued the appeal of the underlying Virginia litigation on July 24, 2025. On September 23, 2025, the Virginia Court of Appeals issued a decision on the appeal, affirming the original lower court decision and judgment against the Company. The Alameda County litigation has continued with several upcoming deadlines related to the already-noticed appeal and Siemens’ motion for fees and costs. The Company continues pursuing global settlement negotiations with Siemens.
The Company recognized $6.9 million as a legal settlement loss related to this litigation as of December 31, 2023. In the thirteen week period ended September 28, 2025, the Company recorded an additional $1.1 million of expense within discontinued operations in its unaudited condensed consolidated statement of operations and comprehensive (loss) to bring the liability for legal settlement with Siemens to $8.0 million as of September 28, 2025. This liability is included within accrued expenses and other current liabilities in the Company’s unaudited condensed consolidated balance sheets.
The Company recorded expense of $2.0 million within discontinued operations in its unaudited condensed consolidated statement of operations and comprehensive (loss) in the thirty-nine week period ended September 29, 2024, for attorneys’ fees, expenses, and pre-judgment interest, and this liability was also recorded within accrued expenses and other current liabilities in the Company’s unaudited condensed consolidated balance sheets as of September 28, 2025, and December 29, 2024.
On December 4, 2025, the Company entered into a Settlement Agreement (“Settlement Agreement”) with Siemens to resolve a case in the Court and other related cases as well as to resolve potential claims related to Siemens’ Atwater Wastewater Treatment Plant. In exchange for full releases, the Company agreed to pay Siemens $9.5 million spread across four payments to be made at the end of each calendar quarter during 2026. If the Company successfully engages in any form of new financing or new debt worth $1.0 million or more, or successfully obtains shareholder approval for the issuance of additional shares in connection with the raise of additional funds and/or any merger or acquisition activity, the next due quarterly payment to Siemens (if any) becomes immediately due and payable. The settlement payment to Siemens is secured by a first-priority continuing security interest in $9.5 of Company collateral. This security interest is reduced on a one-to-one basis as the settlement payments are made.
Letters of credit
The Company had $3.5 million of outstanding letters of credit related to normal business transactions as of September 28, 2025 and December 29, 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 at each of September 28, 2025 and December 29, 2024. |

| Basic and Diluted Net Loss Per Share | (14) Basic and Diluted Net Loss Per Share
The Company uses the two-class method to calculate net loss per share. dividends were declared or paid in the thirteen and thirty-nine week periods ended September 28, 2025 and September 29, 2024.
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 and thirty-nine week periods ended September 28, 2025 and September 29, 2024 (in thousands, except share and per share amounts):
The computation of basic net loss per share attributable to common stockholders is inclusive of warrants with an insignificant exercise price. The Company’s calculation of the weighted average shares outstanding is inclusive of 234,610 warrants with an insignificant exercise price (which assumes that the warrants were outstanding as of the beginning of the period or the date of the grant, whichever is earlier) for each of the thirteen and thirty-nine week periods ended September 28, 2025, respectively. The computation of diluted net loss per share attributable to common stockholders is the same for the thirteen and thirty-nine week periods ended September 28, 2025 and September 29, 2024 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:

| Segment Information | (15) Segment Information
The segment information is presented on a basis that is consistent with the Company’s internal management reporting. The Company’s (“CEO”) is the Chief Operating Decision Maker (“CODM”). The CODM manages the Company and reports financial results based on three reportable segments which are the same as the Company’s operating segments. The CODM evaluates the performance of these reportable segments and allocates resources to make operating decisions based on certain financial information, including segmented internal income/(loss) prepared on a basis consistent with U.S. GAAP. The measurement criteria is based on their operating revenue and operating income (loss) and excluding any corporate costs which are not allocatable to the operating segments. The CODM’s measurement criteria does not include segment assets. During the periods presented, the Company reported its financial performance through the following three reportable segments; Residential Solar Installation, New Homes Business and Sunder.
Residential Solar Installation. This segment performs solar system, storage and battery installations for residential homeowners. New Homes Business. This segment is new, as a result of the SunPower Acquisition which occurred in the fourth quarter of fiscal 2024. The Company developed a method to allocate direct expenses for the respective reportable segments. This segment performs solar system installations for new home builders.
Sunder. This segment is new beginning in fiscal year 2025, as a result of the Sunder Acquisition which occurred late in the third quarter of fiscal 2025. This segment’s principal activity is a solar energy sales force to initiate and execute contracts with customers throughout the United States.

Subsequent to September 28, 2025, holders of $10.6 million of the Company’s September 2024 Notes converted their September 2024 Notes into 6.2 million shares of common stock of the Company.
Acquisition of Ambia Energy LLC
On November 11, 2025, the Company announced that it signed a non-binding letter of intent to acquire Ambia Energy, LLC (“Ambia”) located in Lindon, Utah in exchange for approximately $37.5 million of equity in SunPower, subject to customary closing conditions.
On November 21, 2025, the Company entered into a Membership Interest Purchase Agreement (the “Membership Interest Purchase Agreement”) with Ambia and Ambia Holdings, Inc., a Delaware corporation and the sole member of Ambia (the “Member”). The Company, Ambia and the Member completed the closing under the Membership Interest Purchase Agreement (the “Ambia Closing”) on November 21, 2025. At the Ambia Closing, the Company acquired all of the outstanding membership interests of Ambia from the Member for: (a) 10,243,924 shares (the “Closing Consideration Shares”) of common stock of the Company, $0.0001 par value per share (the “Common Stock”), issued at the Ambia Closing to the Member; and (b) the agreement to issue an additional $9.375 million of shares of Common Stock on the six-month anniversary of the Ambia Closing and an additional $9.375 million of shares of Common Stock on the 12-month anniversary of the Ambia Closing (such additional shares of Common Stock, the “Post-Closing Consideration Shares”). The issuance of the Post-Closing Consideration Shares is subject to approval by the Company’s stockholders following the Ambia Closing in accordance with the rules and regulations of the Nasdaq Stock Market (including Nasdaq Listing Rule 5635(a)). The actual number of Post-Closing Consideration Shares issuable by the Company on the six- and 12-month anniversaries of the Ambia Closing will be determined based on the 20-day trailing volume-weighted average price of the Common Stock after market close on the business day immediate prior to the issuance date of the applicable shares (the “VWAP Value”); provided that the VWAP Value for the calculation of the actual number of Post-Closing Consideration Shares issuable by the Company will not be more than $2.8102 per share or less than $1.4988 per share. Additionally, the number of Post-Closing Consideration Shares issuable by the Company is subject to adjustment pursuant to customary working capital and balance sheet adjustment terms and subject to offset for certain indemnifiable damages in accordance with the Membership Interest Purchase Agreement. Pursuant to the terms and conditions of the Membership Interest Purchase Agreement, the Company agreed to register the Closing Consideration Shares and the Post-Closing Consideration Shares for resale to the public under the Securities Act of 1933, as amended. The Membership Interest Purchase Agreement includes customary representations and warranties, covenants, and indemnities, in each case under the circumstances and subject to certain limitations set forth in the Membership Interest Purchase Agreement. The indemnification obligations under the Membership Interest Purchase Agreement are subject to customary baskets and caps. The Company’s primary source of recovery for indemnifiable damages is set off of such damages against the Post-Closing Consideration Shares issuable by the Company following the Ambia Closing.
The initial accounting for this business combination is incomplete at this time due to the proximity of the Ambia Closing to the issuance date of these condensed consolidated financial statements.

| Basis of presentation | (a) Basis of presentation The interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. The accompanying interim condensed consolidated financial statements are unaudited and have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim unaudited condensed consolidated financial statements do not include all the information and disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, these interim unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s financial position as of September 28, 2025, and the results of operations for the thirteen and thirty-nine week periods ended September 28, 2025 and September 29, 2024. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year or any other future period. These interim unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended December 29, 2024, included in the Company’s Annual Report on Form 10-K filed with the SEC on April 30, 2025. The Company’s operates on a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. The Company’s fiscal year for 2024 ended December 29, 2024.

| Estimated credit losses | (c) Estimated credit losses The Company recognizes an allowance for credit losses at the time a receivable is recorded based on the Company’s estimate of expected credit losses, historical write-off experience, and current account knowledge, and adjusts this estimate over the life of the receivable as needed. The Company evaluates the aggregation and risk characteristics of a receivable pool and develops loss rates that reflect historical collections over the time horizon that the Company is exposed to credit risk, and payment terms or conditions that may materially affect future forecasts. The Company performs ongoing credit evaluations of its customers’ financial condition when deemed necessary. The Company maintains an allowance for credit losses based on the expected collectability of all accounts receivable, which takes into consideration an analysis of historical bad debts, specific customer creditworthiness and current economic trends. The Company believes that its concentration of credit risk is limited because of the large number of customers, credit quality of the customer base, small account balances for most of these customers, and customer geographic diversification. The Company does not have any off-balance sheet credit exposure relating to its customers. The following table summarizes the allowance for credit loss activity as of and for the periods ended (in thousands):

| Contract liabilities | (d) Contract liabilities Contract liabilities consist of deferred revenue and customer advances, which represent consideration received from a customer prior to transferring control of goods or services to the customer under the terms of a sales contract. Total contract liabilities balances as of the respective dates are as follows (in thousands):
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 payment, or when such payment 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 this deferred revenue as a contract liability. Most installation projects are completed within 12-months. As such, a significant portion of the Company’s contract liabilities is reflected within current liabilities in the accompanying condensed consolidated balance sheets. Contract liabilities for installation projects expected to be completed beyond 12 months are classified as noncurrent obligations in the accompanying condensed consolidated balance sheets. |

| Revenue recognition | (e) Revenue recognition Revenue is recognized for Residential Solar Installation and New Homes Business when a customer obtains control of promised products and services and the Company has satisfied its performance obligations which is the date by which substantially all of its design and installation is complete for a fully functioning solar power system to interconnect to the local power grid. Installation includes the design of a solar energy system, the delivery of the components of the solar energy system (i.e., photovoltaic system, inverter, battery storage, etc.), installation services and services facilitating the connection of the solar energy system to the power grid. The Company accounts for these services as inputs to a combined output, resulting in a single service-based performance obligation. The amount of revenue recognized reflects the consideration which the Company expects to be entitled to receive in exchange for the products and services. To achieve this core principle, the Company applies the following five steps: Step 1. Identification of the contract(s) with a customer; Step 2. Identification of the performance obligations in the contracts(s); Step 3. Determination of the transaction price; Step 4. Allocation of the transaction price to the performance obligations; Step 5. Recognition of the revenue when, or as, the Company satisfies a performance obligation. Residential Solar Installation revenues The Company’s Residential Solar Installation segment sells products through a network of installing and non-installing dealers and resellers, as well as its internal sales team. The Company’s contracts with customers include three primary contract types:
New Homes Business revenues The Company’s New Homes Business segment sells through a network of home builders as well as its internal sales team. The Company’s contracts with customers include two primary contract types:
The Company’s performance obligation for both of these reportable segments is to design and install a fully functioning solar energy system. For all contract types (with the exception of New Homes Business Lease agreements), the Company recognizes revenue over time. The Company’s over-time revenue recognition begins when the solar power system is fully installed (as it is at this point that control of the asset begins to be transferred to the customer, and the customer retains the significant risks and rewards of ownership of the solar power system). The Company recognizes revenue using the input method based on direct costs to install the system and defers the costs of installation until such time that control of the asset transfers to the customer (installation). For New Homes Business Lease agreements, the Company considers the performance obligation to be satisfied at a point in time upon acceptance of the system by the customer. Revenue is generally recognized at the transaction price contained within the agreement, net of the costs of financing, or other consideration paid to the customers that is not in exchange for a distinct good or service. The Company’s arrangements may contain clauses that can either increase or decrease the transaction price. Variable consideration is estimated at each measurement date at its most likely amount to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur and true-ups are applied prospectively as such estimates change. The Company records deferred revenue for amounts invoiced that are received in advance of the provisioning of services. In certain contracts with customers, the Company arranges for a third-party financing partner to provide financing to the customer. The Company collects upfront from the financing partner and the customer will provide instalment payments to the financing partner. The Company records revenue in the amount received from the financing partner, net of any financing fees charged to the homeowner, which the Company considers to be a customer incentive. None of the Company’s contracts contain a significant financing component. Sunder The Company earns revenue from contracts sold to customers for solar installations performed by third-party installation companies. The Company recognizes revenue at a point in time when Permission to Operate (“PTO”) is complete. The Company acts as an agent in these arrangements and records revenue on a net basis. The Company does not have significant financing components in its contracts. The Company does not provide warranty services and does not record a warranty reserve. Costs to obtain and fulfill contracts The Company’s costs to obtain and fulfill contracts, when recognized, associated with systems sales are expensed as sales commission and cost of revenue, respectively. In addition, incentives the Company provides to its customers, such as discounts and rebates, are recorded net to the revenue the Company has recognized on the solar power system. Disaggregation of revenue Refer to the table below for the Company’s revenue recognized (in thousands):
All revenue was generated in the United States. Remaining performance obligations The Company elected the practical expedient not to disclose the remaining performance obligations for contracts that are less than one year in length. 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 expenses 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 September 28, 2025 and December 29, 2024, deferred commissions were not material. |

| Recent accounting pronouncements | (g) Recent accounting pronouncements Accounting pronouncements adopted In July 2025, the FASB issued ASU 2025-05 “Measurement of Credit Losses for Accounts Receivable and Contract Assets” which provides an update to all entities with a practical expedient when estimating expected credit losses. This ASU is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. The Company adopted ASU 2025-05 in the thirteen week period ended September 28, 2025. The impact of the adoption was not material to the condensed consolidated financial statements. Accounting pronouncements not yet adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 will adopt this ASU in its annual report for the fiscal year ending December 28, 2025. The Company is assessing the impact of adopting this guidance on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires the disaggregation of certain expenses in the notes of the financial statements to provide enhanced transparency into the expense captions presented on the face of the income statement. The FASB subsequently issued ASU 2025-01 “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date”, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in ASU 2024-03 in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. The Company is assessing the impact of adopting this guidance on its consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-04, Debt-Debt with Conversion and Other Options (Subtopic 470-20) (“ASU 2024-04”). The guidance in ASU 2024-04 clarifies the requirements related to accounting for the settlement of a debt instrument as an induced conversion. The standard is effective for fiscal years beginning after December 15, 2025, and interim periods within fiscal years beginning after December 15, 2025, with early adoption permitted as of the beginning of a reporting period if the entity has also adopted ASU 2020-06 for that period. The Company is currently evaluating the impact that the adoption of ASU 2024-04 may have on its consolidated financial statements. In March 2024, the FASB issued ASU 2024-02 “Codification Improvements-Amendments to Remove References to the Concepts Statements”, which removes various references to concepts statements from the FASB Accounting Standards Codification. This ASU is effective for the Company beginning in the first quarter of fiscal year 2026, with early adoption permitted. The Company expects the new guidance will have an immaterial impact on its consolidated financial statements and intends to adopt the guidance when it becomes effective in the first quarter of fiscal year 2026. In September 2025, the FASB issued ASU 2025-06 “Targeted improvements to the Accounting for Internal-Use Software” which is an update to remove all references to prescriptive and sequential software development stages (referred to as “project stages”). This ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact that the adoption of ASU 2025-06 may have on its consolidated financial statements. |

| SAFE Agreements [Line Items] | |||||||||
| Description of simple agreement for future equity terms and conditions | the Company entered into a Simple Agreement for Future Equity (“SAFE”) (the “First SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (the “Purchaser”), a related party, affiliated with Thurman J. Rodgers, the Company’s Chief Executive Officer and a director, in connection with the Purchaser investing $1.5 million in the Company. The First SAFE did not accrue interest. The First SAFE was initially convertible into shares of the Company’s common stock, par value $0.0001 per share, upon the 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%. | ||||||||
| Description of simple agreement for future equity amendment | the Company entered into an amendment (“First SAFE Amendment”) that converted the First SAFE investment of $1.5 million into 4,166,667 shares of the Company’s common stock based on a conversion price of $0.36 per share, defined in the First SAFE Amendment as the product of (i) $0.45, the closing price of the Company’s common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, the Company recorded a debit to the First SAFE Agreement of $1.5 million, a credit to Additional paid-in-capital of $1.9 million and recognized expense of $0.4 million within Other expense, net in its unaudited condensed consolidated statement of operations in the Company’s second fiscal quarter ended June 30, 2024. | ||||||||
| Second SAFE [Member] | |||||||||
| SAFE Agreements [Line Items] | |||||||||
| Description of simple agreement for future equity terms and conditions | the Company entered into a second SAFE (the “Second SAFE”) with the Purchaser, in connection with the Purchaser investing $3.5 million in the Company. The Second SAFE did not accrue interest. The Second SAFE was initially convertible into shares of the Company’s common stock upon the initial closing of an Equity Financing transaction at a per share conversion price which was equal to the lower of (i) the Second SAFE Price, and (ii) 80% of the price per share of the Company’s common stock sold in an Equity Financing transaction. 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 the Company’s 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%. | ||||||||
| Description of simple agreement for future equity amendment | the Company entered into an amendment (“Second SAFE Amendment”) that converted the Second SAFE investment of $3.5 million into 9,722,222 shares of the Company’s common stock based on a conversion price of $0.36 per share, defined in the Second SAFE Amendment as the product of (i) $0.45, the closing price of the Company’s common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, the Company recorded a debit to the Second SAFE Agreement of $3.5 million, a credit to Additional paid-in-capital of $4.4 million and recognized expense of $0.9 million within Other expense, net in its unaudited condensed consolidated statement of operations in the Company’s second fiscal quarter ended June 30, 2024. | ||||||||
| Third SAFE [Member] | |||||||||
| SAFE Agreements [Line Items] | |||||||||
| Description of simple agreement for future equity terms and conditions | the Company entered into a third SAFE (the “Third SAFE”) with the Purchaser, in connection with the Purchaser investing $1.0 million in the Company. The Third SAFE is convertible into shares of the Company’s common stock 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 issues and sells shares of its common stock in an Equity Financing transaction, at a per share conversion price which is equal to 50% of the price per share of the Company’s common stock sold in an Equity Financing. If the Company consummates a change of control prior to the termination of the Third SAFE, the Purchaser will be automatically entitled to receive a portion of the proceeds of such liquidity event equal to $1.0 million, subject to certain adjustments as set forth in the Third SAFE. The Third SAFE is convertible into a maximum of 2,750,000 shares of the Company’s common stock, assuming a per share conversion price of $0.275, which is the product of (i) $0.55, the closing price of the Company’s common stock on May 13, 2024, multiplied by (ii) 50%. Given that the Third SAFE may be settled in cash or a variable number of shares, the Company has accounted for the instrument as a liability at its fair value. | ||||||||
