SunPower Inc.

(1) Organization

Description of Business

SunPower Inc. (“SunPower” or the “Company”) is the rebranded name of Complete Solaria, Inc. (“Complete Solaria”). The rebranding was effective April 22, 2025 and the Company’s legal name change became effective on October 16, 2025.

The Company was 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, Complete Solar 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. Complete Solaria, Inc. (“Complete Solaria”) was formed in November 2022 through the merger of Complete Solar Holding Corporation, a Delaware corporation (“Complete Solar”), and The Solaria Corporation, a Delaware corporation (such entity, “Solaria,” and such transaction, the “Business Combination”).

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.

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 years ended on December 28, 2025 (“2025”) and December 29, 2024 (“2024”).

Acquisitions and Divestitures

In October 2023, the Company completed the sale of its solar panel business (“Divestiture”). The Company determined that the Divestiture represented a strategic shift in the Company’s business and qualified as a discontinued operation for accounting purposes. The Company recognized losses from discontinued operations in its consolidated statements of operations and comprehensive loss and consolidated statements of cash flows related to the Divestiture of $1.1 million and $2.0 million in the fiscal years ended December 28, 2025 and December 29, 2024, respectively. The additional losses recognized in 2025 and 2024 related to legal expenses incurred in connection with litigation related to its former solar panel business.

In the fiscal year ended December 29, 2024, the Company completed the acquisition of certain assets relating to the Blue Raven Solar business, New Homes business and Non-Installing Dealer network (collectively the “SunPower Businesses”) from SunPower Debtors, the successor entity in bankruptcy to SunPower Corporation and its direct and indirect subsidiaries (collectively “SunPower Corporation”). In the fiscal year ended December 28, 2025, the Company completed the acquisitions of Sunder Energy, LLC and Ambia Energy LLC. Each of these acquisitions was accounted for as business combinations in accordance with Accounting Standards Codification (“ASC”) 805,Business Combination. Refer toNote 3 – Business Combinations for details of these transactions.

Liquidity and Going Concern

Since inception through the fiscal year ended December 28, 2025, the Company has incurred recurring losses and negative cash flows from operations. The Company’s net loss from continuing operations was $44.3 million in the fiscal year ended December 28, 2025. As of December 28, 2025, the Company had an accumulated deficit of $456.7 million, short-term debt of $24.3 million, and cash and cash equivalents, excluding restricted cash, of $9.6 million. The Company anticipates that operating losses and negative operating cash flows may continue in the near term.

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. The Company has financed its operations primarily through sales of equity securities, private placements, debt, issuance of convertible notes and other debt instruments, other financing instruments, cash from operations, and proceeds from the Mergers.

The Company did not file its Annual Report on Form 10-K for the fiscal year ended December 29, 2024 within the timeframe required by the SEC, its Quarterly Report on Form 10Q for the quarter ended September 28, 2025 or the amendment required to the Current Report originally filed on September 26, 2025 relating to the Sunder acquisition. As a result, the Company is not currently eligible to use a registration statement on Form S-3 that would allow it to continuously incorporate by reference its SEC reports into the registration statement, to use “shelf” registration statements to conduct offerings, or to use the at-the-market offering facility until approximately one year from the date that the Company has regained and maintained status as a current filer. Aside from a “shelf” registration, the Company has alternative financing options and may seek additional liquidity through the use of a Form S-1 registration statement and or private placements.

If the Company is not able to secure adequate additional funding when needed, the Company will need to reevaluate its operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs or cease operations entirely. These actions could materially impact the Company’s business, results of operations and future prospects. While the Company has been able to raise multiple rounds of financing, there can be no assurance that in the event the Company requires additional financing, such financing will be available on terms that are favorable, or at all. Failure to generate sufficient cash flows from operations, raise additional capital or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives.

Therefore, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. The accompanying 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) Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The 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.

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, as well as related disclosure of contingent assets and liabilities. Significant estimates and assumptions made by management include, but are not limited to, the determination of (i) the allowance for credit losses; (ii) inventory obsolescence; (iii) stock-based compensation; (iv) workmanship warranty; (v) intangible assets acquired in business combinations; (vi) forward purchase agreements; (vii) Simple Agreement for Future Equity (“SAFE”) Agreements, (viii) derivative liabilities; and (ix) warrant liabilities.

The Company’s financial condition or operating results may be affected to the extent that there are material differences between estimates and actual results. The Company bases its estimates on past experience and other assumptions that the Company believes are reasonable under the circumstances, and the Company evaluates these estimates on an ongoing basis. The Company has assessed the impact and management is not aware of any specific events or circumstances that required an update to the Company’s estimates and assumptions or materially affected the carrying value of the Company’s assets or liabilities as of the date of issuance of this report. These estimates may change as new events occur and additional information is obtained.

Reclassification of prior year balances

The Company reclassified long-term operating lease liabilities of $2.3 million from Operating lease liabilities, net of current portion to Other long-term liabilities to conform to the current year’s presentation.

Segment Reporting

The Company’s segment information is presented on a basis that is consistent with the Company’s internal management reporting. The Company’s Chief Executive Officer (“CEO”) is the Chief Operating Decision Maker (“CODM”). The CODM manages the Company and reports financial results based onthree 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 segment operating results prepared on a basis consistent with U.S. GAAP. The measurement criteria is based on each respective segment’s operating revenue and operating (loss) income and excludes any corporate costs which are not allocatable to the operating segments. The CODM’s measurement criteria does not include segment assets. For the periods presented, the Company reported its financial performance within three reportable segments; Residential Solar Installation, New Homes Business and Dealer.

Residential Solar Installation – This segment performs solar system, storage and battery installations for residential homeowners.

New Homes Business – This segment performs solar system installations for new home builders. This segment was new in fiscal year 2024 as a result of the acquisition of the SunPower Businesses in the fourth quarter of fiscal year 2024.

***Dealer –***This segment provides a third-party solar energy sales force to initiate and execute contracts with customers throughout the United States. This segment’s sales force works with solar installation companies and acts as the agent for each transaction entered. This segment is new in fiscal year 2025 as a result of the acquisition of Sunder.

Concentration of Risks

The Company is exposed to credit losses in the event of nonperformance by the counterparties to its financial and derivative instruments. Financial and derivative instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, and contract assets. The Company’s cash and cash equivalents are on deposit with major financial institutions. Such deposits may be in excess of insured limits. The Company believes that the financial institutions that hold the Company’s cash are financially sound, and accordingly, minimum credit risk exists with respect to these balances. The Company has not experienced any losses due to institutional failure or bankruptcy. The Company performs credit evaluations of its customers and generally does not require collateral for sales on credit.

Cash and Cash Equivalents

Cash and cash equivalents include cash held in checking and savings accounts consisting of highly liquid securities with maturity dates of three months or less from the original date of purchase. The Company maintains the majority of its cash balances with commercial banks in interest bearing accounts. The Company considers all highly liquid securities that mature within three months or less from the original date of purchase to be cash equivalents.

Restricted Cash

The Company classifies all cash for which usage is limited by contractual provisions as restricted cash. Restricted cash consists of deposits in money market accounts, which is used as cash collateral backing letters of credit related to customs duty authorities’ requirements. The Company presents restricted cash as a noncurrent asset in its consolidated balance sheets. The Company reconciles cash, cash equivalents, and restricted cash reported on its consolidated balance sheets that aggregate to the beginning and ending balances shown on the Company’s consolidated statements of cash flows as follows*(in thousands)*:

Concentration of Customers – homeowners and financiers

As of December 28, 2025, one customer had an outstanding balance that represented 11% of the Company’s outstanding trade receivable balance. As of December 28, 2024, no customer had an outstanding balance that represented more than 10% of the Company’s total trade accounts receivable balance.

The Company defines major customers as those customers which generate revenues that exceed 10% of the Company’s annual net revenues by reportable segment. In fiscal 2025 Customer A accounted for 19% of revenues across the Residential Solar Installation and New Homes reportable segments. In fiscal year 2024, Customer A and Customer B accounted for 12% and 14%, respectively, of gross revenues. Customer A generates revenue across the Residential Solar Installation and New Homes reportable segments. Customer B generated revenue within the New Homes reportable segment.

Revenue Recognition

Revenue is recognized for the Residential Solar Installation and New Homes Business reportable segments 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.

Upon entering into a sales contract within the Dealer reportable segment, the requisite performance obligation of the Company is to assist the customer in the progress of the installation and obtain Permission to Operate (“PTO”). PTO typically occurs within 3 to 6 months after the initial sale, but can happen as early as two months or as late as twelve months after the sale.

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.

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 may provide incentives to its customers, such as discounts and rebates which are recorded net against the revenue that the Company has recognized related to the solar energy system sale.

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.

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.

Dealer revenues

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 PTO is complete. The Company acts as an agent in these arrangements and records revenue on a net basis. The Company does not have any significant financing components in these contracts. The Company does not provide warranty services related to these sales contracts, and therefore, the Company does not record a warranty reserve with respect to these sales contracts.

Costs to Obtain Contracts

The incremental costs of obtaining customer contracts consist of sales commissions which are paid to third-parties who source residential customer contracts for the sale of solar energy systems by the Company. The Company defers sales commissions and recognizes the expense in accordance with the timing of the related revenue recognition. Amortization of deferred commissions is recorded as sales commissions in the accompanying consolidated statements of operations and comprehensive loss. As of December 28, 2025 deferred commissions was $5.6 million. Deferred commissions were not material as of December 29, 2024.

Contract Assets and Contract Liabilities

The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, unbilled revenue (contract assets), and deferred revenue (contract liabilities) on the balance sheet.

Contract assets consist of unbilled receivables which represent revenue that has been recognized in advance of the Company’s right to bill the customer.

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

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 consolidated balance sheets. Contract liabilities for installation projects expected to be completed beyond 12 months are classified as noncurrent obligations in the accompanying consolidated balance sheets.

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. The Company’s performance obligations associated with long-term service contracts are not material.

Allowance for 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. In developing its estimate of expected credit losses, the Company has elected to apply the practical expedient permitted under Accounting Standards Codification (“ASC”) 326 –Financial Instruments – Credit Losses, under which it assumes that current conditions at the balance-sheet date remain unchanged for the remaining life of the financial assets.

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 losses as follows*(in thousands)*:

In fiscal year 2024, the Company identified customer accounts receivable balances that were deemed to be uncollectible, which were reserved and written off.

Inventories

Inventories consist of solar panels and the components of solar energy systems all of which are classified as finished goods within inventories as of December 28, 2025 and December 29, 2024. Inventories are valued using the average cost method. The Company identifies inventory which is considered obsolete or in excess of anticipated demand based on a consideration of marketability and product life cycle stage, component cost trends, demand forecasts, historical revenues, and assumptions about future demand and market conditions, and such inventory has been adjusted to its lower of cost or net realizable value.

Cost of Revenues

The Company’s costs to fulfill contracts associated with systems sales are expensed as cost of revenues. Cost of revenues is comprised primarily of materials, internal labor, 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 the Company transfers control of the product to the customer, which is generally upon installation.

Warranties

The Company typically provides a 10-year warranty on its solar energy system installations, which provides assurance over the workmanship in performing the installation, including roof leaks caused by the Company’s performance. For solar panel sales recognized prior to the Divestiture, the Company provides a 30-year warranty that the products will be free from defects in material and workmanship. The Company retained its warranty obligations associated with panel sales prior to the Divestiture.

When revenue is recognized for a solar energy system installation service, the Company accrues a liability for the estimated future cost of meeting its warranty obligations. The Company makes and revises its estimated warranty liability based primarily on the volume of new sales that contain warranties, historical experience with and projections of warranty claims, and estimated solar energy system and panel replacement costs. The Company records a provision for estimated warranty expenses in cost of revenues within the accompanying consolidated statements of operations and comprehensive loss. Warranty costs primarily consist of replacement materials, equipment and labor costs for service personnel.

Property and Equipment, Net

Property and equipment are stated at cost less accumulated depreciation and amortization. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in that period. Repair and maintenance costs are expensed as incurred. Depreciation and amortization are calculated using the straight-line method over the following estimated useful lives of the assets:

Internal-Use Software

The Company capitalizes costs to develop its internal-use software when preliminary development efforts are successfully completed, management has authorized and committed project funding, it is probable that the project will be completed, and the software will be utilized as intended. These costs include personnel and related employee benefits and expenses for employees who are directly associated with and who devote time to software projects, and external direct costs of materials and services consumed in developing or obtaining software. Costs incurred prior to meeting these criteria, together with costs incurred for training and maintenance, are expensed as incurred. Costs incurred for enhancements that are expected to provide additional material functionality are capitalized and amortized over the estimated useful life of the related upgrade.

Intangible Assets, Net

Intangible assets are recorded at cost, less accumulated amortization. Amortization is recorded using the straight-line method. All intangible assets that have been determined to have definite lives are amortized over their estimated useful life as indicated below:

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment, Right-of-Use (“ROU”) assets, and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, and quoted market values, as considered necessary.

The Company recognized an impairment loss ofzero and $3.8 million in the fiscal years ended December 28, 2025 and December 29, 2024, respectively, as disclosed inNote 6 – Supplemental Balance Sheet Information.

Goodwill

The Company tests goodwill at the reporting unit level for impairment annually on the first day of the fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount.

The Company may elect to perform a qualitative assessment that considers economic, industry and company-specific factors. If, after completing the assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company proceeds to a quantitative test. Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. If the carrying value of the reporting unit exceeds its fair value, goodwill impairment is measured as the amount by which the reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of goodwill.

The Company did not recognize any goodwill impairment in the fiscal years ended December 28, 2025 or December 29, 2024.

Fair Value Measurements

The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market.

When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

Financial assets and liabilities held by the Company measured at fair value every reporting period include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, warrant liabilities, forward purchase agreements (“FPAs”), SAFEs, deferred purchase price consideration, and derivative liabilities associated with the Company’s borrowings.

The carrying amounts of cash, accounts receivable, accounts payable, accrued expenses and other current liabilities, public warrants, and deferred purchase price consideration approximate their respective fair values because of their short-term nature or they have observable inputs (classified as Level 1).

The derivative liabilities associated with the Company’s borrowings, FPAs, SAFEs, and private and working capital warrant liabilities are initially measured at fair value using Level 3 inputs. At each subsequent reporting date, the Company remeasures the fair value of these instruments in accordance with ASC 820,Fair Value Measurement, and records the respective adjustment to the fair value within Other non-operating income, net the Company’s consolidated statements of operations and comprehensive loss.

Borrowings with Embedded Derivative Liabilities

The Company accounts for its borrowings with embedded derivative liabilities in accordance with ASC 815,Derivatives and Hedging, to determine whether such features must be bifurcated and accounted for separately as derivative liabilities. Upon issuance of a debt instrument with an embedded conversion option feature, the Company assesses whether the embedded feature qualifies as a derivative that requires bifurcation from the host contract. An embedded feature is bifurcated and accounted for as a separate derivative instrument if (i) the economic characteristics and risks of the embedded feature are not clearly and closely related to those of the host debt instrument; (ii) the embedded feature, if freestanding, would meet the definition of a derivative; and (iii) the hybrid instrument is not remeasured at fair value through earnings.

If an embedded feature requires bifurcation, the Company allocates a portion of the initial proceeds to the fair value of the derivative liability, with the residual assigned to the carrying amount of the host debt instrument. The derivative liability is subsequently measured at fair value at each reporting date.

The host debt instrument is recorded at amortized cost using the effective interest method. Any discounts or premiums resulting from the initial allocation between the host debt and the embedded derivative are amortized as interest expense over the expected term of the debt.

Derivative liabilities are measured at fair value in accordance with ASC 820,Fair Value Measurement. The fair value of a derivative liability is measured using a Monte Carlo simulation that incorporates a binomial lattice model. Refer toNote 5 – Fair Value Measurements andNote 10 – Borrowings and Derivative Liabilitiesfor details.

Forward Purchase Agreements

The Company accounts for its FPAs in accordance with the guidance in ASC 480,Distinguishing Liabilities from Equity, as the agreements embody an obligation to transfer assets to settle a forward contract. The FPAs are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820,Fair Value Measurement. Refer toNote 5 – Fair Value Measurements andNote 8 – Forward Purchase Agreementsfor details.

Warrant Liabilities

The Company accounts for its warrant liabilities in accordance with the guidance in ASC 815-40,Derivatives and Hedging – Contracts in Entity’s Own Equity, under which the warrants that do not meet the criteria for equity classification must be recorded as liabilities. The warrant liabilities are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820,Fair Value Measurement. Refer toNote 5 – Fair Value Measurements andNote 14 – Common Stock and Common Stock Warrantsfor details.

SAFE Agreements

The Company accounts for its SAFEs in accordance with the guidance in ASC 480,Distinguishing Liabilities from Equity. SAFEs are measured at fair value at inception and at each reporting date in accordance with the guidance in ASC 820,Fair Value Measurement. Refer toNote 5 – Fair Value Measurements andNote 9 – SAFE Agreementsfor details.

Advertising and Promotion Expenses

Advertising and promotion costs are expensed as incurred and included in sales and marketing expense in the accompanying consolidated statements of operations and comprehensive loss. Advertising costs were not material for the fiscal years ended December 28, 2025 and December 29, 2024.

Income Taxes

Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is established when it is more likely than not that the deferred tax assets with not be realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in its income tax provision.

On July 4, 2025, Public Law No. 119-21, commonly known as the One Big Beautiful Bill Act (the “OBBBA”), was enacted in the United States, resulting in broad-based changes to federal tax law. The Company included the impact of OBBBA in its income tax provision for the fiscal year ended December 28, 2025. The OBBBA did not have a material impact on income tax expense for the fiscal year ended December 28, 2025.

Stock-Based Compensation

The Company recognizes stock-based compensation expense over the requisite service period on a straight- line basis for all stock-based payments that are expected to vest to employees, non-employees and Directors, including grants of employee stock options and other stock-based awards. Equity-classified awards issued to employees, non-employees such as consultants and non-employee Directors are measured at the grant-date fair value of the award. Forfeitures are recognized as they occur.

Comprehensive Loss

Comprehensive loss consists of two components, net loss and other comprehensive income (loss), net.

Net Loss Per Share

The Company computes net loss per share following ASC 260,Earnings Per Share. Basic net loss per share is measured as the loss attributable to common stockholders divided by the weighted average common shares outstanding during periods with undistributed losses. Diluted net loss per share of common stock is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method and if-converted method, as applicable. Securities that potentially have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the diluted loss per share calculation.

The Company accounts for its leases following ASC 842,Leases. The Company determines if a contract is a lease or contains a lease at the inception of the contract and reassesses that conclusion if the contract is modified. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease.

The Company’s lease agreements generally contain lease and non-lease components. Payments under lease arrangements are primarily fixed. The Company has elected the practical expedient to combine lease and non-lease components and accounts for them together as a single lease component. All leases are assessed for classification as an operating lease or a finance lease. Finance lease ROU assets are classified within Property and Equipment, net, on the Company’s consolidated balance sheets. Operating lease ROU assets are classified separately on the Company’s consolidated balance sheets. Operating lease liabilities and finance lease obligations are separated into their respective current portion and non-current portions and are presented separately on the Company’s consolidated balance sheets. Finance lease ROU assets and liabilities and operating lease ROU assets and liabilities are recognized on the Company’s consolidated balance sheet on the date in which the lessor makes the underlying asset available for use.

Finance lease ROU assets are those that meet one or more of the criteria outlined in ASC 842-10-25-2, such as transfer of ownership, purchase option, lease term for a major part of the asset’s economic life, or present value of lease payments substantially equal to the fair value of the asset. Finance lease ROU assets are initially measured at cost, which includes the initial lease liability, plus any lease payments made at or before commencement, less any lease incentives received. Finance lease ROU assets are amortized on a straight-line basis over the shorter of the lease term or the useful life of the underlying asset. Interest expense on the finance lease liability is recognized using the effective interest method.

Operating lease ROU assets and liabilities are recognized based upon the present value of the lease payments over the respective lease term. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or expectation regarding the terms. Variable lease costs such as common area maintenance, property taxes and insurance are expensed as incurred.

The Company generally uses its incremental borrowing rate to discount the lease payments to present value. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The Company’s lease terms include periods under options to extend or terminate the lease. Options to renew or extend leases beyond their initial term have been excluded from measurement of the ROU assets and lease liabilities when exercise of such options is not reasonably certain. The Company generally uses the base, non-cancellable, lease term when determining the lease assets and liabilities. The Company records a right-of-use asset which is calculated based on the amount of the lease liability, adjusted for any advance lease payments made, lease incentives received, and initial direct costs incurred. Right-of-use assets are subject to evaluation for impairment or disposal on a basis consistent with other long-lived assets.

The Company has elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with an initial term oftwelve months or less. The cost for short-term leases is recognized on a straight-line basis over the term of the contract.

Recently Adopted Accounting Pronouncements

In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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.

(3) Business Combinations

SunPower Businesses Acquisition

On August 5, 2024, the Company entered into an Asset Purchase Agreement (the “APA”) with SunPower Corporation and SunPower Corporation’s direct and indirect subsidiaries (collectively, the “SunPower Debtors”) providing for the sale and 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 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 transaction was approved on September 23, 2024, by the United States Bankruptcy Court for the District of Delaware. The Company completed the acquisition of the Acquired Assets (as defined in the APA) effective September 30, 2024, in the Company’s fourth quarter of fiscal year 2024, in consideration for a cash purchase price of $54.5 million (“SunPower Acquisition”). The assets and businesses acquired, including liabilities assumed, by the Company under the APA are referred to herein as the “SunPower Businesses.”

Prior to its acquisition, the SunPower Businesses operated as 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 Businesses have been included in the Company’s consolidated financial statements since its date of acquisition. This transaction was accounted for as a business combination in accordance with ASC 805*.*

Transaction costs of $7.2 million incurred in connection with the close of the SunPower Businesses were expensed by the Company and included in general and administrative expenses on the Company’s statement of operations and comprehensive loss in the fiscal year ended December 29, 2024.

The provisional fair values of assets acquired and liabilities assumed initially recorded were based upon a preliminary valuation in the fiscal year ended December 29, 2024. Upon finalization of the fair values in the fiscal year ended December 28, 2025, the Company recorded adjustments to acquired inventory related to (1) the resolution of 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, 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 settlement of these matters resulted in adjustments to the provisional fair values of the inventory and intangibles with an offsetting adjustment to goodwill during the measurement period.

The following table summarizes the provisional and final fair values of identifiable assets acquired and liabilities assumed and measurement period adjustments*(in thousands)*:

The provisional and final fair values of the intangible assets acquired and estimated useful lives were as follows:

The fair values of the trademarks were estimated using the relief-from-royalty method. This approach measures the value of the asset based on the hypothetical royalties the Company would avoid paying if it had to license the trademark from a third party. The analysis considers the established history and longevity of the trade names, including the Blue Raven brand, in use since 2014, and the SunPower brand, which has been in the market for over 20 years. Key assumptions include projecting sales attributable to business enterprise value for each respective business, applying a 1% royalty rate derived from a profit-split analysis and benchmarking against the median of comparable licensing arrangements, and utilizing a 10-year economic life in line with management’s plans to continue using the brands for the foreseeable future.

The fair value of the developed technology was estimated using the cost approach, which measures the economic resources required to recreate the asset, including direct costs and necessary entrepreneurial incentives. Direct costs were based on management’s estimate of the fees and profit margin that would be required to engage external consultants to rebuild the technology. In addition, an opportunity cost was incorporated to reflect the hypothetical return foregone during the development period, representing the income that could have been earned had these funds been invested elsewhere. The total replacement cost was calculated assuming a weighted-average redevelopment period of 19 months.

The SunPower Acquisition contributed $83.8 million and $6.5 million in revenue and income before income taxes from continuing operations, respectively, for the period from the acquisition date to the fiscal year ended December 29, 2024.

Sunder Energy LLC Acquisition

On September 21, 2025, a subsidiary of the Company entered into a Membership Interest Purchase Agreement (“Sunder MIPA”) with Sunder Energy LLC (“Sunder”) and the seller, Chicken Parm Pizza LLC (“Seller/Member”), the sole member of Sunder. On September 24, 2025 (“Sunder Closing”), the Company completed the acquisition of the membership interests of Sunder for an aggregate consideration of $57.8 million (“Sunder Acquisition”). Per the terms of the Sunder 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”); and (3)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 issued at the Sunder Closing and (ii) subject to approval of such issuances by the Company’s stockholders, (x)3,333,333 shares of the Company’s common stock to be issued on the 12-month anniversary of the Sunder Closing and (y)3,333,333 shares of the Company’s common stock to be issued on the 18-month anniversary of the Sunder Closing (“Deferred Sunder Consideration Shares”). In lieu of issuing the Deferred Sunder Consideration Shares, the Company, in its sole discretion, may elect to pay the Member a cash payment equal to the number of Deferred Sunder 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 endingtwo business days prior to the date on which the applicable Deferred Sunder Consideration Shares are 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 Sunder Consideration Shares are 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 Sunder Consideration Shares are otherwise issuable. The shares of the Company’s common stock issued and expected to be issued were valued at aggregate of $17.1 million at the date of acquisition. The common stock issued at the Sunder Closing was valued at $5.7 million and accounted for within Additional paid-in-capital on the Company’s consolidated balance sheet. The Deferred Sunder Consideration Shares payable is presented as noted below on the Company’s consolidated balance sheet as of December 28, 2025. The fair value of the Sunder deferred consideration was subsequently adjusted downward to $10.8 million from the Sunder Closing to December 28, 2025. The Company concluded that since the sellers joined the Company and represent members of management, they have a level of influence that is not insignificant, they are related parties of the Company, and therefore the Deferred Consideration and Seller Note are a related party obligations.

The consideration is summarized as follows*(in thousands):*

The Company financed a portion of the transaction through the issuance of $22.0 million of 7.0% senior unsecured convertible notes (the “September 2025 Notes”) and a $20.0 million Seller Note. Refer toNote 10 – Borrowings and Derivative Liabilities for details regarding these obligations.

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. The financial results of Sunder have been included in the Company’s consolidated financial statements since its date of acquisition.

The provisional fair values of assets acquired and liabilities assumed were based upon a preliminary valuation, and the Company’s estimates and assumptions have been revised during the measurement period to refine the fair values of the assets acquired and liabilities assumed based upon the facts and circumstances existing at the date of acquisition which resulted in the measurement period adjustments noted below. The purchase price accounting remains open for the components of working capital, identification and valuation of intangibles and allocation of goodwill. 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 (“ASC 606”) 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:

The fair value of customer relationships was estimated using the excess earnings method, which measures the cash flows attributable to existing customers after deducting all supporting expenses and contributory asset charges. The assumptions used included revenue included all business enterprise valuation sales, reduced by a 5% attrition rate based on historical customer turnover, with operating expenses estimated as a percentage of sales and no sales-and-marketing adjustment since such efforts do not directly support existing customers. Contributory asset charges were applied for the use of working capital, fixed assets, workforce, trademarks, and internal-use software, and cash flows were projected over the period in which customer relationships were expected to produce meaningful benefit, with the economic life extending until those cash flows became minimal.

The fair value of the trademark was estimated using the relief-from-royalty method. This approach measures the value of the asset based on the hypothetical royalties the Company would avoid paying if it had to license the trademark from a third party. The assumptions used to value the trademark included projected sales based upon the business enterprise valuation considered attributable to the trademark, a royalty rate of 1.0% supported by a profit-split analysis and benchmarking against comparable licensing arrangements in the solar and broader energy industries and a useful economic life of 10 years consistent with management’s expectations for continued use and the anticipated longevity of the brand’s market relevance.

The fair value of Sunder’s developed technology was estimated using the cost approach, which measures value based on the cost to reproduce or replace the existing software in its current state. The analysis considered the historical direct development costs, including Sunder’s ongoing investment of approximately since late 2023, representing labor, design, coding, and testing efforts required to build the technology. In addition to direct costs, the valuation incorporated opportunity costs, which reflect the portion of the software expected to be added, modified, or removed over time based on management’s estimates of ongoing development needs. Together, these inputs approximate the current replacement cost of the technology, adjusted for necessary updates and functional improvements.

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.

Sunder contributed $14.4 million and $6.2 million in revenue and income before income taxes from continuing operations, respectively, for the period from the acquisition date to the fiscal year ended December 28, 2025.

Ambia Energy LLC Acquisition

On November 21, 2025, the Company entered into a Membership Interest Purchase Agreement (the “Ambia MIPA”) with Ambia and Ambia Holdings, Inc., a Delaware corporation and the sole member of Ambia (“Ambia Holdings”) to acquire Ambia (the “Ambia Acquisition”). Ambia was the sole operating entity within Ambia Holdings.

The Company, Ambia and Ambia Holdings completed the closing under the Ambia MIPA on November 21, 2025 (the “Ambia Closing”). At the Ambia Closing, the Company acquired all of the outstanding membership interests of Ambia from Ambia Holdings for: (a)10,243,924 shares of common stock of the Company (the “Ambia Closing Consideration Shares”), issued at the Ambia Closing to Ambia Holdings; and (b) an agreement to issue an additional $9.375 million of shares of the Company’s common stock on each of the six-month anniversary of the Ambia Closing and the 12-month anniversary of the Ambia Closing (collectively such additional shares of common stock, the “Deferred Ambia Consideration Shares”). The issuance of the Deferred Ambia Consideration Shares is subject to approval by the Company’s stockholders following the Ambia Closing.

The actual number of Deferred Ambia 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 Company’s common stock after market close on the business day immediately 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 Deferred Ambia 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 Deferred Ambia 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 Ambia MIPA.

The fair value of the deferred consideration shares at the Ambia Closing was $16.9 million. The Company’s closing share price for its common stock of $1.61 on November 21, 2025 was used to fair value the shares issued at the Ambia Closing. The total consideration is summarized as follows*(in thousands):*

Ambia is a residential solar energy system installer and operates in various markets throughout the United States.

The provisional fair values of assets acquired and liabilities assumed were based upon the facts and circumstances existing at the date of acquisition. The purchase price accounting remains open for the valuation of the customer relationship and allocation of goodwill. The Company 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 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 provisional fair values of identifiable assets acquired and liabilities assumed are identified below*(in thousands)*:

As of the date of acquisition, the intangible assets acquired and estimated useful lives were as follows:

(1)Useful life is based upon customer consumption, expected to occur within one year.

Trademarks were derived using the relief from royalty method based upon the following key assumptions; (i) all sales based upon the business enterprise value; (ii) a royalty rate of 1% based upon profit split analysis and comparable licensing royalty agreements and (iii) an economic life of the Ambia name through the end of 2026, the Ambia name will only be used in certain small markets and that all sales, marketing and branding will be done under the SunPower brand name in relatively short order.

Customer relationships (backlog) was derived using the excess earnings method based upon the following key assumptions: (i) backlog meets the appropriate contractual criteria; (ii) sales were based upon the backlog of sales; (iii) expenses were based upon a percentage of sales with an adjustments for sales and marketing expenses, upon which management estimates that 100% of Ambia’s sales and marketing expenses are directed at acquiring new customers and is not required to support the backlog; (iv) charges were taken for the use of working capital, fixed assets, workforce and trademarks; (v) the economic life of the backlog is to the end of fiscal 2026 based upon management’s estimate of average deal length.

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.

Ambia contributed $7.0 million and $2.8 million in revenue and loss before income taxes from continuing operations, respectively, for the period from the acquisition date to the fiscal year ended December 28, 2025.

Subsequent to issuance, changes in the fair value of derivative liabilities, FPAs, SAFEs and liability classified warrants, are recorded within Other non-operating income, net on the Company’s consolidated statements of operations and comprehensive loss. Refer toNote 11*–* Other Non-Operating Income, Net for details.

Derivative liabilities

The Company recognized derivative liabilities arising from the conversion features of its senior unsecured convertible notes issued in the years ended December 28, 2025 and December 29, 2024 (refer toNote 10 – Borrowings and Derivative Liabilities). Derivative liabilities are measured at fair value in accordance with ASC 820,Fair Value Measurement. The fair value of each respective derivative liability is measured using a Monte Carlo simulation that incorporates a binomial lattice model. Significant inputs to the binomial lattice model include the terms of the senior unsecured convertible notes (including the interest rate, conversion rate and conversion price), the underlying price of the Company’s common stock, risk-free rate and volatility. Certain of these inputs are unobservable. Thus, these derivative liabilities are classified within Level 3 of the fair value hierarchy. The binomial lattice model produces an estimated fair value based on changes in the price of the underlying shares of the Company’s common stock over successive periods of time. As a result of these interrelationships and inherent unobservable assumptions, the fair value of a derivative liability is subject to significant measurement uncertainty, and alternative reasonable assumptions could have produced materially different results as of December 28, 2025 and December 29, 2024.

The assumptions used to value the derivative liabilities as of December 28, 2025 were as follows:

The assumptions used to value the derivative liabilities as of December 29, 2024 were as follows:

Forward purchase agreement liabilities

FPAs are measured at fair value on a recurring basis using a Monte Carlo simulation analysis based upon the following inputs:

The volume-weighted average price (“VWAP”) reflects management’s judgment regarding expected future trading activity and price behavior as an active forward market does not exist for the Company’s common stock. Reasonably possible alternative VWAP outcomes at the reporting date could have resulted in a materially different fair value. The risk-free rate is derived from the applicable tenor of the U.S. Treasury yield curve. Changes in the risk-free rate would alter the present value of the simulated settlement amounts and could significantly impact the fair value estimate. The expected volatility is determined based on the historical equity volatility of comparable companies over a period that matches the simulation period. Because expected volatility drives the dispersion of simulated price paths, reasonably higher or lower volatility assumptions could materially increase or decrease the estimated fair value. These inputs are interrelated, and changes in one may affect the others. As a result of these interrelationships and inherent unobservable assumptions, the fair value of FPAs is subject to significant measurement uncertainty, and alternative reasonable assumptions could have produced materially different results as of December 28, 2025 and December 29, 2024. Thus, FPAs are classified within Level 3 of the fair value hierarchy.

Private placement and working capital warrants

The Company valued the private placement and working capital warrants, based on a binomial lattice model, which included the following inputs:

The expected term is the time period to the expiration date of the warrants. The risk-free rate is interpolated from the U.S. Constant Maturity Treasury curve for a term matching the corresponding remaining life. Volatility was calibrated based on the public warrants closing price as of the valuation date. As the private and working capital warrants have terms nearly identical to the publicly traded warrants, the volatility was calibrated until the model price equaled the public warrants closing price. These inherent unobservable assumptions are subject to significant measurement uncertainty, and alternative reasonable assumptions could have produced materially different results as of December 28, 2025 and December 29, 2024. Thus, the private placement and working capital warrant liabilities are classified within Level 3 of the fair value hierarchy.

Public warrants

The public warrants are measured at fair value on a recurring basis. The public warrants were valued based on the closing price of the publicly traded instrument and therefore are considered a Level 1 instrument in the fair value hierarchy.

SAFE agreement with related party

The Company measured the fair value of its SAFE using a valuation technique that incorporates significant unobservable inputs and is therefore classified within Level 3 of the fair value hierarchy. The fair value of the SAFE is subject to estimation uncertainty because it depends on management’s judgments about future events that are not directly observable in active markets. Management assigned a 50% probability that the SAFE will convert into shares of the Company’s stock in connection with a qualifying financing or other specified event. If the SAFE does not convert, management expects cash repayment in fiscal 2026 or fiscal 2027, with a 50% probability assigned to each repayment year.

The SAFE valuation also considers assumptions such as discount rates implied by the Company’s convertible notes as of the valuation date, the timing and likelihood of financing or liquidity events, and, for the conversion path, the expected equity valuation and any applicable conversion economics (e.g., discounts or valuation caps). Settlement of the SAFE is contingent on future financing or liquidity events and the Company’s funding plans. Accordingly, the measurement requires judgment about the likelihood and timing of conversion versus repayment and, where relevant, assumptions about the Company’s equity value at conversion. Because these factors are not directly observable, reasonably possible alternative assumptions at the reporting date could produce a materially different fair value. Increasing the probability of conversion would generally increase the fair value if the conversion terms imply a beneficial outcome to the holder relative to repayment; decreasing that probability would place more weight on the repayment scenarios and could increase or decrease the fair value depending on the applicable discount rate and timing of cash flows. Within the non-conversion path, shifting probability weight toward repayment in fiscal year 2026 would generally increase fair value (lower discounting), while shifting weight toward fiscal 2027 would generally decrease fair value (greater discounting), holding other inputs constant. A higher discount rate would decrease the present value of expected cash flows (and thus fair value), while a lower rate would increase fair value. Higher expected equity values or more favorable conversion economics would increase the fair value under the conversion path; lower expected equity values or less favorable terms would decrease it. These inputs are interrelated and unobservable. Because the valuation depends on significant unobservable inputs—including a 50% probability of conversion to equity and an even allocation between fiscal years 2026 and 2027 of repayment if conversion does not occur—there is significant measurement uncertainty, and alternative reasonable assumptions at the reporting date could have resulted in a materially different fair value of the SAFE liability as of December 28, 2025 and December 29, 2024. Thus, the SAFE liability is classified within Level 3 of the fair value hierarchy.

Financial liabilities not measured at fair value

The Company’s senior unsecured convertible notes were fair valued using a binomial lattice model, which includes Level 3, unobservable inputs. The key inputs used are consistent with those used to fair value the derivative liabilities as discussed underDerivative Liabilities above. The following table sets forth the Company’s financial liabilities that were not measured at fair value and are considered a Level 3 instrument in the fair value hierarchy*(in thousands)*:

(8) Forward Purchase Agreements

On and around July 13, 2023, FACT (now SunPower, formerly Complete Solaria, Inc. following the closing of the Business Combination) entered into separate Forward Purchase Agreements (“FPAs”) with (i) Meteora Special Opportunity Fund I, LP, Meteora Capital Partners, LP, and Meteora Select Trading Opportunities Master, LP (collectively, “Meteora”), (ii) Polar Multi-Strategy Master Fund (“Polar”), and (iii) Diametric True Alpha Market Neutral Master Fund, LP, Diametric True Alpha Enhanced Market Neutral Master Fund, LP, and Pinebridge Partners Master Fund, LP (collectively, “Sandia,” and together with Meteora and Polar, the “FPA Investors”). Under the FPAs, the Company agreed to purchase, subject to certain terms and limitations, up to 5,618,488 shares of common stock held by the FPA Investors on a date 24 months after execution of the FPAs (the “Maturity Date”). The FPA Investors agreed not to redeem their Class A ordinary shares in connection with the Business Combination, and the FPAs originally provided the FPA Investors with a minimum sale price of $5.00 per share at maturity.

On December 18, 2023, the Company entered into amendments with each FPA Investor reducing the reset floor price from $5.00 to $3.00 and permitting the Company to raise up to $10.0 million of equity from existing stockholders without triggering anti-dilution protections, subject to specified per-share pricing requirements for insider investments. On May 7 and 8, 2024, the Company executed additional amendments with Sandia and Polar reducing the reset price to $1.00 per share and modifying the volume-weighted average price (“VWAP”) trigger event to occur if, after December 31, 2024, the Company’s VWAP is below $1.00 for 20 out of 30 consecutive trading days. On June 14, 2024, the Company and Sandia executed an additional amendment confirming a $1.00 reset price and the revised VWAP trigger and providing that Sandia will automatically receive any more favorable terms provided to Polar or Meteora, including with respect to the shares sold upon execution of its FPA. On July 17, 2024, the Company and Polar executed an amendment applying the “Most Favored Nation” provision of the Polar FPA to all of its shares covered by that agreement.

Between July 15 and August 1, 2025, the Company entered into further amendments with Meteora, Sandia, and Polar that extended the valuation date applicable to the FPAs to the earliest of (i) July 17, 2026, (ii) a date specified by Meteora or Sandia, as applicable, or (iii) 90 days after Company notice if the Company’s VWAP is below the applicable reset price for 20 out of 30 consecutive trading days occurring at least six months after the closing of the Business Combination, provided that a registration statement is effective throughout both the measurement and notice periods. These amendments also revised the settlement provisions to clarify that the Settlement Amount is used solely as a calculation mechanism to determine any liability owed by the Company to an FPA Investor. If the Settlement Amount Adjustment exceeds the Settlement Amount, the excess will be paid to the FPA Investor in cash or shares, at the Company’s election, and the FPA Investors are not required to remit the Settlement Amount or return any prepayment to the Company.

If the FPA Investors continue to hold some or all of the FPA shares on the Maturity Date and the trading price of the Company’s common stock is below the applicable FPA sale price, the Company expects the FPA Investors to exercise their repurchase rights.

In connection with these FPAs, the Company has recorded a liability on its consolidated balance sheets of $4.0 million and $3.5 million as of December 28, 2025 and December 29, 2024, respectively.

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 4.2 million 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 to shares of the Company’s common stock, the Company recognized $1.9 million of Additional paid-in capital, and a loss on conversion of the First SAFE of $0.4 million within Other non-operating income, net in its consolidated statement of operations for the fiscal year ended December 29, 2024.

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, and (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 9.7 million 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 to shares of the Company’s common stock, the Company recognized $4.4 million of Additional paid-in capital, and a loss on conversion of the Second SAFE of $0.9 million within Other non-operating income, net in its consolidated statement of operations for the fiscal year ended December 29, 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, at a per share conversion price which is equal to 50% of the price per share of the Company’s common stock sold in the 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 SAFE could 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 SAFE liability represents the estimated fair value of the Company’s obligation to issue equity in the future. The fair value of the Third SAFE approximated $0.5 million and $0.4 million as of December 28, 2025 and December 29, 2024, respectively. Refer toNote 5 – Fair Value Measurements for details.

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 held 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 with such that no amounts were required to 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 $9.5 million and $7.7 million recorded within accrued expenses and other current liabilities on its consolidated balance sheets as of December 28, 2025 and December 29, 2024, respectively.

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.

On March 16, 2023, SolarPark filed a complaint against 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, the Company 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 on the Company’s 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 “Circuit 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 Circuit 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 Circuit Court entered a final order which awarded Siemens a total of $2.0 million in attorneys’ fees and costs. The Company 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 recognized $6.9 million as a legal settlement loss related to this litigation as of December 31, 2023. The Company recorded additional expense of $1.1 million and $2.0 million within discontinued operations in the years ended December 28, 2025 and December 29, 2024, respectively, for attorneys’ fees, expenses, and pre-judgment interest related to this matter. The legal settlement liability associated with this matter is included within accrued expenses and other current liabilities on the Company’s consolidated balance sheet as of December 28, 2025.

On December 4, 2025, the Company entered into a global Settlement Agreement (“Settlement Agreement”) with Siemens to resolve the case 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 million of Company collateral. This security interest is reduced on a one-to-one basis as the settlement payments are made.

LGCY Power, LLC Matter

LGCY Power, LLC (“LGCY”) markets and sells residential solar energy systems throughout the United States, and is a competitor of the Company. In 2019, LGCY filed suit against Sunder and several individuals associated with Sunder. LGCY asserts claims of over $16.0 million against Sunder and its associated individuals. LGCY’s claims against Sunder and its associated individuals center on the alleged misappropriation of LGCY’s confidential information, the alleged wrongful solicitation of LGCY’s customers and potential customers, and the alleged wrongful solicitation of LGCY’s sales representatives. In addition, several of the Sunder associated individuals have filed counterclaims against LGCY for declaratory relief, unjust enrichment, and breach of contract based on LGCY’s failure to pay these individuals earned sales commissions following their resignations as LGCY sales managers. LGCY denies these claims. The Company denies LGCY’s claims.

The Company has assumed the defense of the case, including the costs of defense, following the Company’s acquisition of Sunder in September 2025. Under the terms of the Sunder MIPA, the Seller agreed to indemnify the Company in the event of damages (such as a settlement or an adverse judgement) stemming from LGCY’s claims, separate and apart from their other indemnification obligations or limitations in the Sunder MIPA. Discovery is complete and no trial date has been set. Both sides have filed various summary judgment motions, and oral arguments for these motions are scheduled for July 2, 2026.

Based upon information currently available, management is unable to determine the probability of an adverse outcome or to reasonably estimate the amount or range of potential loss, if any. Accordingly, no provision for loss has been recorded in the accompanying consolidated financial statements. While the ultimate resolution of these matters could have a material effect on the Company’s results of operations, cash flows, or financial position, management believes that the resolution will not have a material adverse effect on the Company’s financial condition

Letters of Credit

The Company had $3.5 million of outstanding letters of credit as of December 28, 2025 and December 29, 2024. The Company is required to maintain specified amounts of cash as collateral in segregated accounts to support the letters of credit issued thereunder. As discussed inNote 2 – Summary of Significant Accounting Policies, the cash collateral in these restricted cash accounts was $3.8 million at each of December 28, 2025 and December 29, 2024.

(13) Income Taxes

The Company’s loss from continuing and discontinued operations before provision for income taxes for the fiscal years ended December 28, 2025 and December 29, 2024, was as follows*(in thousands)*:

The components of income tax benefit from continuing and discontinued operations were as follows (in thousands):

The Company adopted ASU 2023-09 prospectively for the fiscal year ended December 28, 2025. The following table presents required disclosure pursuant of ASU 2023-09 and reconciles the Company’s federal statutory tax amount and rate, based on its results from continuing operations, to its actual effective amount and rate:

The following table represents the required disclosures prior to the Company’s adoption of ASU 2023-09 and is a reconciliation of the Company’s income tax applied at the federal statutory income tax rate compared to the income tax provision reported on its consolidated statements of operations for continuing operations.(in thousands):

Significant components of deferred tax assets and liabilities are as follows.(in thousands):

Management regularly assesses its ability to realize deferred tax assets recorded based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income on a jurisdiction by jurisdiction basis. In the event that the Company changes its determination as to the amount or realizable deferred tax assets, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. The Company’s management believes that, based upon a number of factors, it is more likely than not that all or some portion of the deferred tax assets will not be realized. Accordingly, for the fiscal years ended December 28, 2025 and December 29, 2024, the Company provided a valuation allowance against its U.S. net deferred tax assets of $70.3 million and$55.7 million, respectively. The net change in the valuation allowance was an increase of $14.6 million and $17.3 million in the fiscal years ended December 28, 2025 and 2024, respectively.

As of December 28, 2025, the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $131.4 million and $114.8 million, respectively. Excluding $115.3 million of federal net operating losses which carryforward indefinitely, thenet operating loss carryforwards will expire between 2030 and 2044.

The Internal Revenue Code (“IRC”) of 1986, as amended, imposes restrictions on the utilization of net operating losses in the event of an “ownership change” of a corporation. Accordingly, a company’s ability to use net operating losses may be limited as prescribed under IRC Section 382. Events which may cause limitations in the amount of the net operating losses that the Company may use in any one year include, but are not limited to, a cumulative ownership change of more than 50% over a three-year period. Utilization of the federal and state net operating losses may be subject to substantial annual limitation due to the ownership change limitations provided by IRC Section 382 and similar provisions. Such limitations may result in the expiration of these carryforwards before their utilization. The Company’s acquired net operating loss carryforwards have been reduced based on the estimated amount which will be lost due to these limitations. If the Company has experienced subsequent ownership changes, the Company’s losses may be further limited, which may result in the expiration of net operating losses before utilization. To date, Company has not yet completed a Section 382 ownership change analysis. During the fiscal year ended December 29, 2024, the Company had undergone restructuring and strategic transformation, including the completion of the SunPower Businesses. As a result of the change in facts and lack of certainty regarding the acquired losses of the legacy Solaria business, the Company wrote off the remaining acquired net operating losses as the Company does not intend to pursue the potential tax benefits as it believes those benefits will be lost due to the continuation of business enterprise rules. As a result, the corresponding uncertain tax position was also reversed as the Company does not intend to pursue utilization of those attributes.

The Company files income tax returns in the U.S for federal and various state jurisdictions as well as foreign jurisdictions each of which have varying statutes of limitations. The Company is in the process of filing returns for prior years, and the penalties related to the delinquent filings are not material. Due to the history of losses, the Company’s tax years remain open for examination by all tax authorities since inception. The Company is not currently under examination in any tax jurisdictions.

The Company has no unrecognized tax benefits as of December 28, 2025 and December 29, 2024, respectively. The reversal of the uncertain tax benefits would not affect the Company’s effective tax rate to the extent that it continues to maintain a full valuation allowance against its deferred tax assets. As outlined above, the reduction in the uncertain tax positions during the fiscal year ended December 29, 2024, is a result of the Company’s decision to forgo the right to certain acquired attributes for which the Company does not intend to claim any tax benefits.

The Company applies the provisions set forth in FASB ASC Topic 740, Income Taxes, to account for the uncertainty in income taxes. In the preparation of income tax returns in federal and state jurisdictions, the Company asserts certain tax positions based on its understanding and interpretation of income tax laws.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits*(in thousands)*:

The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in its consolidated statements of operations and comprehensive loss. Accrued interest and penalties are included as part of income tax payable in the consolidated balance sheets. No accrued interest or penalties have been recorded for the fiscal years ended December 28, 2025 and December 29, 2024.

The Company did not pay any federal, state or foreign income taxes during the fiscal year ended December 28, 2025.

The Company has not provided U.S. income or foreign withholding taxes on the undistributed earnings of its foreign subsidiary as of December 28, 2025 or December 29, 2024, as there are no undistributed earnings within the foreign subsidiaries, which were inactive throughout the years ended December 28, 2025 and December 29, 2024.

The OBBA enacted on July 4, 2025 contains significant changes to corporate taxation, including accelerated deductions for capital expenditures, expensing of research and development costs incurred in the U.S., and increased deductibility of interest expense. As the Company maintains a full valuation allowance against its deferred tax assets, any adjustments to the gross value of these assets resulting from the enactment of the OBBBA were offset by a corresponding change in the valuation allowance, resulting in no net impact to the consolidated financial statements. The Company will continue to monitor the impact of the OBBBA as additional guidance is issued and further provisions become effective in future periods.

(14) Common Stock and Common Stock Warrants

Common Stock

The Company has authorized the issuance of 1,000,000,000 shares of common stock and 10,000,000 shares of preferred stock as of December 28, 2025. No preferred stock has been issued andnone are outstanding as of December 28, 2025 and December 29, 2024.

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 4.0 million and 2.9 million shares of the Company’s common stock for proceeds of $6.7 million and $6.7 million in the years ended December 28, 2025 and December 29, 2024, respectively.

SeeNote 20 – Subsequent Events for information regarding an amendment to the White Lion SPA entered into on after the fiscal year ended December 28, 2025.

Employee Stock Purchase Plan

The Company adopted the Employee Stock Purchase Plan (the “ESPP Plan”) in July 2023. All qualified employees may voluntarily enroll to purchase the Company’s common stock through payroll deductions at a price equal to 85% of the lower of the fair market value of the stock in the offering period or the applicable purchase date.

Common Stock 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 718Compensation – 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 $9.2 million in the year ended December 29, 2024 for the Ayna Warrant.

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 Cantor Fitzgerald & Co., (“Cantor”) 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 toNote 10 – 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 theExchange Agreement (as described inNote 10 – 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 inNote 10 – 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 is recorded within additional paid-in capital on the Company’s consolidated balance sheets and has not been subsequently remeasured in future periods as it met the conditions for equity classification.

Shares of common stock reserved for future issuance

The Company has reserved shares of common stock for issuance related to the following:

(15) Stock-Based Compensation

In July 2023, the Company’s Board of Directors adopted and stockholders approved the 2023 Incentive Equity Plan (the “2023 Plan”). The 2023 Plan became effective immediately upon the closing of the Amended and Restated Business Combination Agreement. Initially, a maximum number of 8,763,322 shares of the Company’s common stock may be issued under the 2023 Plan. In addition, the number of shares of the Company’s common stock reserved for issuance under the 2023 Plan automatically increases on January 1 of each year, effective January 1, 2024 through January 1, 2033, in an amount equal to the lesser of (1)4% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding year, or (2) a lesser number of shares of the Company’s common stock determined by the Company’s Board of Directors prior to the date of the increase. The maximum number of shares of the Company’s 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”) (collectively with the 2023 Plan, “the Plans”). Under the Plans, the Company has granted service-based stock options and restricted stock units (“RSUs”). Compensation expense for stock options under the Company’s cliff vesting schedule is generally recognized equally over the vesting period of five years. RSUs granted during the fiscal year ended December 28, 2025 are also generally recognized under the cliff vesting schedule that is recognized equally over the vesting period of five years.

The information below summarizes the stock option activity under the Plans.

The aggregate fair value of the Company’s stock options that vested during the fiscal years ended 2025 and 2024 was $0.4 million and $1.9 million, respectively.

The information below summarizes the RSU activity.

The aggregate fair value of the Company’s RSUs that vested during the fiscal years ended 2025 and 2024 was $8.1 million and $1.2 million, respectively.

Determination of Fair Value

The Company estimated the grant-date fair value of stock options using the Black-Scholes-Merton option-pricing model. The determination of the fair value of each stock award using this option-pricing model is affected by the Company’s assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the awards. Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award.

The following assumptions were used to calculate the fair value of stock-based compensation for the options granted in the fiscal year ended December 29, 2024:

Expected term — The Company uses the simplified method to calculate the expected term of stock option grants to employees as the Company does not have sufficient comparable historical exercise data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. The expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally 10 years).

Expected volatility — Due to the Company’s limited operating history and a lack of company specific historical and implied volatility data, the Company has based its estimate of expected volatility on the historical volatility of a group of peer companies that are publicly traded. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards.

Risk-free interest rate — The risk-free rate assumption is based on U.S. Treasury instruments with maturities similar to the expected term of the Company’s stock options.

Expected dividends — The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options and therefore has estimated the dividend yield to be zero.

Fair value of common stock — The fair value of the shares of common stock underlying the stock-based awards is based on the price of the Company’s common stock in the open market on the date of the grant.

Stock-based compensation expense

The following table summarizes stock-based compensation expense and its allocation within the accompanying consolidated statements of operations and comprehensive loss*(in thousands)*:

As of December 28, 2025, there was a total of $1.1 million and $23.1 million of unrecognized stock-based compensation costs related to service-based options and RSUs, respectively. Such compensation cost is expected to be recognized over a weighted-average period of approximately 2.4 years and 4.0 years, respectively.

In fiscal 2024, the Company’s Board of Directors approved the modification to accelerate the vesting of 788,192 options, for employees that were terminated. Additionally, the Board of Directors approved an extension of the post termination exercise period for 4,343,172 vested options of terminated employees in the fiscal years ended December 29, 2024. In connection with the modifications, the Company recorded incremental stock-based compensation expense of $0.7 million in the fiscal year ended December 29, 2024.

(16) Basic and Diluted Net Loss Per Share

The Company uses the two-class method to calculate net loss per share. No dividends were declared or paid in the fiscal years ended December 28, 2025, or December 29, 2024.

The following table sets forth the computation of the Company’s basic and diluted net loss per share attributable to common stockholders*(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 and the minimum number of shares to be issued in connection with the deferred consideration related to the Ambia acquisition.
