The accompanying notes are an integral part of these unaudited condensed consolidated financial statements. 4 SUNPOWER INC. Notes to Unaudited Condensed Consolidated Financial Statements (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. References to the Company and SunPower include the same entity under its previous name of Complete Solaria. The Company is headquartered in Orem, Utah. 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”). 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”). The Company operates on a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. The Company’s first fiscal quarters for 2026 and 2025 in this report on Form 10-Q ended on March 29, 2026 (“Q1 2026”) and March 30, 2025 (“Q1 2025”), respectively. Acquisitions In the fiscal year ended December 28, 2025, the Company completed the acquisitions of Sunder Energy, LLC (“Sunder”) and Ambia Energy LLC (“Ambia”). On February 2, 2026, the Company completed the acquisition of Cobalt Power Systems, Inc. (“Cobalt”). Each of these acquisitions was accounted for as a business combination in accordance with Accounting Standards Codification (“ASC”) 805, Business Combination. Refer to Note 3 – Business Combinations for details of these transactions. Liquidity and going concern The Company’s operating loss was $ 19.2 million in the thirteen weeks ended March 29, 2026. As of March 29, 2026, the Company had an accumulated deficit of $ 451.5 million, current debt of $ 38.0 million, and cash and cash equivalents, excluding restricted cash, of $ 9.5 million. The Company anticipates that operating losses and negative operating cash flows will 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 stockholders 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 Quarterly Report on Form 10-Q 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, within the timeframe required by the SEC. 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 a 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. 5 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 unaudited condensed consolidated financial statements are issued. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business. They do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern. (2) Basis of Presentation and Summary of Significant Accounting Policies Basis of presentation The interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. The accompanying interim unaudited condensed consolidated financial statements are unaudited and have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim unaudited condensed consolidated financial statements do not include all the information and disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, these interim unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s financial position as of March 29, 2026, and the results of operations for the thirteen weeks ended March 29, 2026 and March 30, 2025. These interim unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended December 28, 2025, included in the Company’s Annual Report on Form 10-K filed with the SEC on April 14, 2026. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year or any other future period. Cash and cash equivalents and restricted cash The Company reconciles cash, cash equivalents, and restricted cash reported in its unaudited condensed consolidated balance sheets that aggregate to the beginning and ending balances shown in the Company’s unaudited condensed consolidated statements of cash flows as follows (in thousands) : As of March 29, 2026 December 28, 2025 Cash and cash equivalents $ 9,488 $ 9,617 Restricted cash 1,134 3,841 Total cash, cash equivalents and restricted cash $ 10,622 $ 13,458 6 Use of estimates The preparation of interim unaudited condensed consolidated financial statements requires management to make estimates and assumptions that affect reported amounts. Revenue recognition The Company recognizes revenue in accordance with ASC 606 – Revenue from Contracts with Customers (“ASC 606”) when control of the promised products and services is transferred to the customer and its performance obligations are satisfied. The Company’s performance obligation in its Residential Solar Installation and New Homes Business segments is to design and install a fully functioning solar energy system. The design, delivery of system components, installation, and services facilitating interconnection to the power grid are accounted for as a single performance obligation. Revenue is recognized in the amount of consideration the Company expects to be entitled to receive, net of customer incentives such as discounts or rebates, and variable consideration is estimated at each reporting date to the extent it is probable that a significant reversal will not occur. Amounts invoiced and collected in advance of performance are recorded as deferred revenue. The Company’s contracts do not contain significant financing components. For Residential Solar Installation and New Homes Business cash and financing arrangements, revenue is generally recognized over time beginning when the system is fully installed, as this is when the customer obtains control of the asset. Revenue is recognized using an input method based on direct installation costs. For New Homes Business lease arrangements, revenue is recognized at a point in time upon customer acceptance of the completed system. In the Dealer segment, the Company earns revenue from contracts for solar installations performed by third-party installers. The Company acts as an agent in these arrangements and recognizes revenue on a net basis at the point in time when substantial completion is achieved. The Company does not provide warranty services related to Dealer contracts. During the thirteen week period ended March 29, 2026, the Company amended customer contracts and under the amended contractual terms, the point at which control transfers to the customer changed from permission to operate (“PTO”) to substantial completion of the installation. As a result, the Company recognized incremental revenue of $ 12.4 million in the thirteen week period ended March 29, 2026, related to the contract modifications. Incremental costs of obtaining customer contracts As of March 29, 2026 and December 28, 2025, deferred commissions were $ 8.1 million and $ 5.6 million, respectively.

On January 30, 2026, the Company entered into a Share Purchase Agreement (the “Share Purchase Agreement”) with Cobalt and Cobalt’s stockholders (the “Cobalt Stockholders”). The Company, Cobalt and the Cobalt Stockholders completed the closing under the Share Purchase Agreement (the “Cobalt Closing”) on February 2, 2026. At the Cobalt Closing, the Company acquired all of the outstanding stock of Cobalt from the Cobalt Stockholders for: (a) 1.8 million shares (the “Closing Consideration Shares”) of the Company’s common stock and (b) an agreement to issue an additional $ 3.33 million of shares of the Company’s common stock on each of the 12-month and 18-month anniversaries of the Cobalt Closing (“Post-Closing Consideration Shares). Additionally, the Company agreed to issue up to $ 2.0 million of restricted stock units to those Cobalt employees who continue their employment with the Company following the Cobalt Closing, and 850,000 restricted stock units will be issued as inducement grants to certain Cobalt key employees. Based on the analysis of the payments made or to be made in connection with the acquisition of Cobalt under ASC 805, the Company concluded that the $ 2.0 million of restricted stock units is considered compensation and, therefore, this amount has been excluded from the business combination consideration. Cobalt designs and installs solar systems for residential and commercial clients. Total consideration for Cobalt was $ 9.66 million, which consists of $3.33 million paid at the Cobalt Closing and Post-Closing Consideration Shares valued at $ 6.33 million. The $ 3.33 million fair value of the shares of common stock issued at the Cobalt Closing was derived based on the Company’s closing stock price in a 5-day volume-weighted average price (“VWAP”) immediately preceding the Cobalt Closing to determine the number of shares issued. The Post-Closing Consideration Shares are treated as a liability for financial reporting purposes and are reported within Deferred consideration, current and deferred consideration, noncurrent within the Company’s unaudited condensed consolidated balance sheet, and were valued using a Monte Carlo simulation model to capture the variability in the number and value of shares issuable at the 12- and 18-month post-closing dates. Under the terms of the agreement, the deferred obligation represents a fixed dollar amount that will be settled in a variable number of shares determined based on the 5-day VWAP immediately prior to each issuance date, resulting in an inverse relationship between share price and shares issued. The model incorporates key assumptions, including a starting VWAP of $ 1.69 , a risk-free rate of 3.53 %, expected volatility of 85.5 % derived from peer company analysis and historical data, and a 1.5 -year simulation horizon. For each simulated stock price path, the model calculates the resulting share issuances and corresponding payment values, discounts those amounts to present value, and averages the outcomes across simulations to estimate fair value, resulting in a concluded value of approximately $ 6.33 million as of the valuation date. The total consideration is summarized as follows (in thousands): Consideration Fair value of shares of the Company’s common stock issued at Cobalt Closing (classified within Additional paid-in capital) $ 3,333 Deferred Cobalt Consideration Shares (Classified within Deferred consideration, current and noncurrent) 6,331 Fair value of total consideration $ 9,664 The provisional fair values of assets acquired and liabilities assumed were based upon the facts and circumstances existing at the Cobalt Closing. The purchase price accounting remains open for the valuation of intangibles, certain liabilities 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) : Provisional fair values as of Cobalt Closing Net assets acquired: Cash and cash equivalents $ 553 Trade accounts receivable, net 3,642 Inventories 1,739 Prepaid expenses and other current assets 30 Property and equipment, net 485 Intangible assets, net 3,871 Operating lease right-of-use assets 1,277 Accounts payable ( 3,864 ) Accrued expenses and other current liabilities ( 1,002 ) Short-term debt with third parties ( 2,706 ) Other long-term liabilities ( 1,099 ) Contract liabilities ( 5,238 ) Deferred tax liability ( 1,001 ) Fair value of the excess of liabilities assumed over assets acquired ( 3,313 ) Fair value of common stock issued 3,333 Fair value of Deferred Cobalt Consideration Shares 6,331 Consideration transferred 9,664 Goodwill recognized $ 12,977 9 As of the date of acquisition, the intangible assets acquired and estimated useful lives were as follows: Estimated useful life Provisional fair values as of the Cobalt Closing Customer relationships (Backlog) 18 months $ 1,100 Trade name – Cobalt 10 years 2,000 Building lease intangible asset – favorable lease 6 years 771 Total $ 3,871 The fair value of the backlog was estimated using the excess earnings method, an income-based approach, under which value is determined based on the present value of the cash flows attributable specifically to the backlog after deducting appropriate returns for contributory assets. Projected revenues were based on the contractual backlog existing as of the valuation date, and operating expenses were estimated as a percentage of revenue, with an adjustment to exclude sales and marketing expenses. Based on management’s estimates, substantially all sales and marketing efforts relate to acquiring new customers and are not required to fulfill the existing backlog. Contributory asset charges were applied for the use of working capital, fixed assets, assembled workforce, and trademarks. The trade name’s fair value was estimated using the relief-from-royalty method, which measures the present value of avoided royalty payments. The valuation considered qualitative factors such as Cobalt’s long operating history since 2003, strong reputation for affordable and reliable solar solutions, and established market presence with over 2,400 installations. It assumed the trade name supports all revenues and applied a 1.0 % royalty rate based on profit-split analysis and market data. The trade name was assigned a 10 -year useful life, reflecting expected continued use and brand support The fair value of the building lease was estimated using an income approach, specifically a discounted cash flow model, reflecting the present value of the difference between contractual rent and estimated market rent over the remaining lease term. Key assumptions include a market rent derived from comparable properties, a 2.0 % annual rental growth rate, and an 8.50 % discount rate consistent with market participant return expectations and leasehold-specific risks. 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 not deductible for tax purposes. Cobalt contributed $ 5.0 million and $ 0.3 million in revenue and income before income taxes from operations, respectively, for the period from the acquisition date to March 29, 2026. Sunder Energy LLC 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 (“CPP”), 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) 3.3 million 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) 3.3 million shares of the Company’s common stock to be issued on the 12-month anniversary of the Sunder Closing and (y) 3.3 million 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 ending two 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 six-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 Sunder Closing. 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. 10 On April 23, 2026, the Company and CPP entered into an amended and restated Seller Note that, following certain payoffs under the prior Seller Note, has an amended principal amount of $ 7.0 million (the “A&R Seller Note”). Refer to Note 18 – Subsequent Events for details. On March 25, 2026, the Company’s stockholders approved the issuance of the Deferred Sunder Consideration Shares, and the Company’s option to pay the Cash in Lieu Amount expired. Accordingly, the value of the Deferred Sunder Consideration Shares became fixed on that date. The fair value of the 6.7 million Deferred Sunder Consideration Shares was $ 8.5 million as of March 25, 2026. Under ASC 815-40, Derivatives and Hedging , as all of the substantive contingencies have been resolved and only remaining condition is the passage of time, the obligation met the criteria for equity classification. As such, the Company reclassified the Deferred Sunder Consideration Shares obligation from liability to equity as of March 29, 2026. Pursuant to an Amendment and Agreement dated as of March 5, 2026 between CPP and the Company, the Company agreed to issue all of the Deferred Sunder Consideration Shares following receipt of approval by the Company’s stockholders, and the Deferred Sunder Consideration Shares were subsequently issued on April 8, 2026. Refer to Note 18 – Subsequent Events for details. 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; therefore, they are related parties to the Company. 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 consideration initially paid and remaining payable as of the date of the Sunder Closing is summarized below (in thousands): Consideration Paid at Sunder Closing Cash $ 20,689 Seller note 20,000 Fair value of 3.3 million shares of the Company’s common stock 5,700 Payable subsequent to Sunder Closing Deferred Sunder Consideration Shares (fair value of 6.7 million shares of the Company’s common stock at Sunder Closing) 11,400 Fair value of total consideration at Sunder Closing $ 57,789 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 Seller Note in the original principal amount of $ 20.0 million, which has been amended by the A&R Seller Note in the principal amount of $ 7.0 million subsequent to March 29, 2026. Refer to Note 9 – Borrowings and Derivative Liabilities and Note 18 – Subsequent Events for details regarding these obligations. 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 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. 11 The following table summarizes the provisional fair value of identifiable assets acquired and liabilities assumed. No measurement period adjustments were recorded in the thirteen week period ended March 29, 2026. ( in thousands ) Provisional fair values Net assets acquired: Accounts receivable $ 797 Prepaid expenses and other current assets 3,039 Property and equipment 241 Operating lease right-of-use assets 313 Other noncurrent assets 135 Intangibles 37,500 Contract liabilities ( 11,673 ) Accounts payable ( 203 ) Accrued expenses and other current liabilities ( 3,850 ) Operating lease liabilities ( 332 ) Fair value of net assets acquired 25,967 Consideration transferred 57,789 Goodwill recognized $ 31,822 Intangible assets acquired and estimated useful lives were as follows ( in thousands ): Estimated useful life Provisional fair values Customer relationships 10 years $ 30,600 Trademark - Sunder 10 years 6,100 Developed technology - Sunder 2 years 800 Total $ 37,500 The fair value of customer relationships was estimated using the excess earnings method. 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. 12 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 in 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. Ambia Energy LLC 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. Ambia is a residential solar energy system installer and operates in various markets throughout the United States. 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. On March 25, 2026, the Company’s stockholders approved the issuance of the Deferred Ambia Consideration Shares. 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 initial 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): Consideration Fair value of 10,243,924 shares of the Company’s common stock issued at Ambia Closing $ 16,493 Deferred Ambia Consideration Shares 16,879 Fair value of total consideration $ 33,372 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. 13 There have been no measurement period adjustments since the Ambia Closing.

Derivative liabilities The Company recognized derivative liabilities arising from the conversion features of its senior unsecured convertible notes issued (refer to Note 9 – 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 March 29, 2026 and December 28, 2025. 18 The assumptions used to value the derivative liabilities as of March 29, 2026 were as follows: 12.0% Senior Unsecured Convertible Notes 7.0% Senior Unsecured Convertible Notes July 2024 Notes (1) July 2025 Note November 2025 Note January 2026 Note September 2024 Notes (1) September 2025 Notes (1) Coupon rate 12.0 % 12.0 % 12.0 % $ 12.0 % 7.0 % 7.0 % Initial conversion rate 595.24 558.66 626.96 540.54 467.84 467.84 Initial conversion price $ 1.68 $ 1.79 $ 1.60 $ 1.85 $ 2.14 $ 2.14 Common stock price $ 1.25 $ 1.25 $ 1.25 $ 1.25 $ 1.25 $ 1.25 Risk-free interest rate 4.00 % 4.00 % 3.96 % 4.00 % 3.96 % 3.96 % Volatility 88.1 % 88.8 % 87.5 % 89.2 % 90.7 % 90.7 % Dividend yield 0.00 % 0.00 % 0.00 % 0.00 % 0.00 % 0.00 % The assumptions used to value the derivative liabilities as of December 28, 2025 were as follows: 12.0% Senior Unsecured Convertible Notes 7.0% Senior Unsecured Convertible Notes July 2024 Notes (1) July 2025 Note November 2025 Note September 2024 Notes (1) September 2025 Notes (1) Coupon rate 12.0 % 12.0 % 12.0 % 7.0 % 7.0 % Initial conversion rate 595.24 558.66 626.96 467.84 467.84 Initial conversion price $ 1.68 $ 1.79 $ 1.60 $ 2.14 $ 2.14 Common stock price $ 1.62 $ 1.62 $ 1.62 $ 1.62 $ 1.62 Risk-free interest rate 3.6 % 3.6 % 3.6 % 3.58 % 3.58 % Volatility 82.2 % 83.2 % 81.3 % 85.6 % 85.6 % Dividend yield 0.00 % 0.00 % 0.00 % 0.00 % 0.00 % (1) The conversion option is derived based upon the above assumptions plus a make-whole provision which is based upon changes in the Company’s stock price and the conversion date. $1.9 Million Note and March 2026 Bridge Note The Company elected the fair value option under ASC 825 for the $1.9 Million Note (as defined in Note 9 – Borrowings and Derivative Liabilities) issued on January 27, 2026 in connection with the Standby Equity Purchase Agreement (as defined in Note 9 – Borrowings and Derivative Liabilities ) and the March 2026 Bridge Note (as defined in Note 9 – Borrowings and Derivative Liabilities) issued on March 6, 2026. The $1.9 Million Note and March 2026 Bridge Note were measured at fair value on a recurring basis and classified as a Level 3 liability due to the use of significant unobservable inputs. The Company estimated the fair value of each obligation using a Monte Carlo simulation model, which captures the economic characteristics of the instrument, including its variable conversion price feature that is dependent on future market prices of the Company’s common stock. The Company utilized a “Bond plus Option” approach, where the value of upside plus amortization was determined in a simulation and the value related to principal repayment was calculated as a single payment of principal at maturity. The Company simulated its stock price from the valuation date to maturity date, at a daily step. With respect to the $1.9 Million Note, on each of the simulated paths, the Company (i) tested for an amortization trigger as applicable; and (ii) assumed that the maturity date will not be extended. Once the payoffs for all simulation paths were determined according to above, they were discounted back to the valuation date at the risk-free rate in case the $1.9 Million Note would be converted and at credit risk-adjusted rate otherwise. 19 With respect to the March 2026 Bridge Note, on each of the simulated paths, the Company determined the maximum payoff on each installment date based on conversion price. Once the payoffs for all simulation paths were determined according to above, they were discounted back to the valuation date at the risk-free rate in case the March 2026 Bridge Note would be converted and at credit risk-adjusted rate otherwise. The fair value of these obligations was each calculated as the average present value across all simulation paths plus present value of debt component. The model was calibrated to transaction proceeds by varying credit risk-adjusted rate in the model. The change in yields between the valuation dates was applied to the credit risk-adjusted rate to account for market changes. Thus, these obligations are classified within Level 3 of the fair value hierarchy as the fair values are based upon unobservable inputs. The key inputs for the simulation include stock price, simulation period and volatility of the Company’s common stock and were as follows as of March 29, 2026: $1.9 Million Note March 2026 Bridge Note VWAP stock price $ 1.24 $ 1.24 Simulation period 0.83 years 0.94 years Risk-free rate 3.76 % 3.77 % Volatility 81.4 % 83.3 % Credit risk-adjusted rate 41.4 % 73.4 % The fair value measurement reflects a probability-weighted assessment of settlement outcomes, including conversion into equity versus cash repayment scenarios, and captures the optionality inherent in the instrument. Changes in these assumptions, particularly stock price volatility, credit spread, and the likelihood of conversion, can result in significant fluctuations in the estimated fair value. Changes in fair value are recognized in operating results within “Other non-operating income, net,” in the Company’s unaudited condensed consolidated statements of operations and comprehensive income, and no separate interest expense is recorded, as the fair value measurement incorporates the economic cost of the financing. 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. 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: As of March 29, December 28, 2026 2025 Expected term 2.31 years 2.56 years Stock price $ 1.25 $ 1.62 Exercise price $ 11.50 $ 11.50 Expected volatility 268.3 % 179.0 % Risk-free rate 3.90 % 3.50 % Expected dividend yield 0.00 % 0.00 % 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 March 29, 2026 and December 28, 2025. Thus, the private placement and working capital warrant liabilities are classified within Level 3 of the fair value hierarchy. 20 Forward purchase agreement (“FPA”) liabilities FPAs are measured at fair value on a recurring basis using a Monte Carlo simulation analysis based upon the following inputs: As of March 29, December 28, 2026 2025 VWAP stock price $ 1.24 $ 1.66 Simulation period 0.30 years 0.55 years Risk-free rate 3.73 % 3.57 % Volatility 58.0 % 77.3 % 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 March 29, 2026 and December 28, 2025. Thus, FPAs are classified within Level 3 of 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 March 29, 2026 and December 28, 2025. Thus, the SAFE liability is classified within Level 3 of the fair value hierarchy. 21 Deferred Ambia Consideration Shares The Deferred Ambia consideration is classified within Level 3 of the fair value hierarchy. The Company estimated the fair value of the deferred consideration shares using a Turnbull–Wakeman closed-form approximation for arithmetic average-rate options, with Black-Scholes values used as an upper bound. The valuation as of March 29, 2026, was based on a stock price of $ 1.25 and key assumptions including expected volatility of approximately 52 % to 72 %, risk-free rates of approximately 3.74 % to 3.76 %, zero dividend yield, and defined averaging periods over the contractual terms. The resulting fair values reflect per-unit option values of approximately $ 0.26 to $ 0.38 corresponding to total estimated value of $ 13.9 million. The fair value of the deferred consideration shares as of December 28, 2025 of $ 16.9 million was estimated using the Company’s closing share price for its common stock of $ 1.61 at 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 was 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. Financial liabilities not measured at fair value on a recurring basis: 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 under Derivative Liabilities above.

(8) SAFE Agreement Third SAFE On May 13, 2024, the Company entered into a third SAFE (the “Third SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (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 $ 0.6 million and $ 0.5 million as of March 29, 2026 and December 28, 2025, respectively. Refer to Note 5 – Fair Value Measurements for details. On April 23, 2026, the SAFE was converted and exchanged into $ 1.0 million principal amount of the Company’s 10.0 % convertible secured notes due 2029.

Pursuant to the SEPA, YA agreed to advance up to $ 20.0 million (the “Pre-Paid Advances”) to the Company in the form of convertible promissory notes (each “Promissory Note”), subject to the terms and conditions of the SEPA. Each Promissory Note bears interest at 0 % per annum, which increases to 18 % per annum upon the occurrence and continuance of an Event of Default (as defined in the Promissory Notes) for so long as such event remains uncured. Each tranche is funded at a 10 % discount to its principal amount. The Promissory Notes are initially convertible into 540.5405 shares of the Company’s common stock per $ 1,000 principal amount, subject to adjustment. The SEPA also provides the Company the right, subject to certain conditions, to require YA to purchase up to $ 25.0 million of the Company’s common stock (“Commitment Amount”) through January 27, 2029. In connection with the SEPA, the Company paid YA total fees of $ 0.4 million consisting of $ 0.05 million of cash and 175,000 shares of the Company’s common stock, with a fair value of $ 0.3 million, as a due diligence, structuring and commitment fee. The SEPA will automatically terminate on the earliest to occur of (i) January 27, 2029 or (ii) the date on which YA has purchased from the Company under the SEPA the Commitment Amount in full. The Company may terminate the SEPA at any time upon five trading days’ prior written notice to YA, provided that there are no outstanding advance notices under which the Company is yet to issue shares of its common stock, there are no amounts outstanding under the Promissory Notes, and provided that the Company has paid all amounts owed to YA pursuant to the SEPA. The Company and YA may also agree to terminate the SEPA by mutual written consent. On January 27, 2026, the first Pre-Paid Advance was disbursed. The gross amount of the borrowing under the Pre-Paid Advance was $ 1.9 million which was advanced under a Promissory Note (“$ 1.9 Million Note”), and the Company received net proceeds of $ 1.71 million after the contractual discount. The $ 1.9 Million Note matures on January 27, 2027, which may be extended at YA’s option. The Company’s rights for further Pre-Paid Advances under the SEPA terminated pursuant to the terms of the SEPA. The Company elected the fair value option under ASC 825, Financial Instruments, for the $1.9 Million Note. Accordingly, the $1.9 Million Note is recorded at fair value upon issuance and are subsequently remeasured at fair value at each reporting date, with changes in fair value recognized in “non-operating Other non-operating income, net” in the Company’s unaudited condensed consolidated statements of operations and comprehensive income. As a result of this election, the original issue discount, transaction costs, and embedded conversion features are not separately accounted for and are instead reflected in the fair value of $1.9 Million Note. The $1.9 Million Note is classified as a Level 3 liability within the fair value hierarchy established by ASC 820, Fair Value Measurement , due to the use of significant unobservable inputs in the valuation. Refer to Note 5 – Fair Value Measurements for a description of the inputs and assumptions used in the valuation of the $ 1.9 Million Note. The initial amount of the $ 1.9 Million Note was recorded at its estimated fair value of $ 1.7 million on the issuance date. As of March 29, 2026, the $ 1.9 Million Note had a fair value of $ 1.5 million. The change in the fair value of the $ 1.9 Million Note was included in “Other non-operating income, net” within the unaudited condensed consolidated statement of operations and comprehensive income in the thirteen week period ended March 29, 2026. 27 March 2026 Bridge Note On March 6, 2026, the Company entered into a purchase agreement (“Purchase Agreement”) with YA pursuant to which the Company issued a convertible debenture in the principal amount of $ 10.0 million (the “March 2026 Bridge Note” and collectively with the $ 1.9 Million Note, the “Yorkville Notes”). The Company received net proceeds of $ 9.0 million at issuance, after deducting fees payable under the Purchase Agreement. The March 2026 Bridge Note matures on March 6, 2027, unless extended at YA’s option. The March 2026 Bridge Note bears interest at 0 % per annum; however, upon the occurrence and continuance of an event of default, the interest rate increases to 18 % per annum. The Company elected the fair value option under ASC 825 for the March 2026 Bridge Note. As a result, the March 2026 Bridge Note is carried at fair value, with changes in fair value recognized in earnings within “non-operating Other non-operating income, net” in the Company’s unaudited condensed consolidated statements of operations and comprehensive income. As a result of this election, the original issue discount, transaction costs, and embedded conversion features are not separately accounted for and are instead reflected in the fair value of the March 2026 Bridge Note. The March 2026 Bridge Note is classified as a Level 3 liability within the fair value hierarchy established by ASC 820 due to the use of significant unobservable inputs in the valuation. See Note 5 – Fair Value Measurements for additional information regarding the valuation of the March 2026 Bridge Note, including key assumptions and valuation methodologies. The initial amount of the March 2026 Bridge Note was recorded at its estimated fair value of $ 9.0 million on the issuance date. As of March 29, 2026, the March 2026 Bridge Note had a fair value of $ 9.5 million.

The March 2026 Bridge Note required installment payments on May 6, 2026, June 6, 2026, July 6, 2026, August 6, 2026, and September 6, 2026 (each, an “Installment Date”). On each Installment Date, the Company was required to pay an amount equal to (i) $ 2.0 million of principal, (ii) a payment premium of $ 0.06 million, and (iii) any accrued and unpaid interest (collectively, the “Installment Amount”). The Company may satisfy each Installment Amount, at its option, (a) in cash, (b) by submitting an advance notice pursuant to the SEPA, or (c) through a combination of cash and such advance notice. On April 21, 2026, the Company and YA agreed to amend the Installment Dates in connection with a $ 5.0 million prepayment of the March 2026 Bridge Note. As amended, on each of May 5, 2026, June 5, 2026, July 5, 2026 and August 5, 2026, the Company is required to pay an amount equal to (i) $ 1.25 million of principal, (ii) a payment premium of $ 0.0375 million, and (iii) any accrued and unpaid interest. Refer to Note 18 – Subsequent Events for details. At any time after issuance, YA may convert all or a portion of the outstanding principal balance into shares of the Company’s common stock at an adjusted fixed conversion price of $ 1.64 per share (the “Fixed Price”). In addition, any Installment Amount that remains unpaid following an Installment Date may be converted at a price equal to 95 % of the volume weighted average price (“VWAP”) of the Company’s common stock during the five trading days immediately preceding the conversion date, subject to a minimum conversion price equal to the then-applicable floor price. The Company may, at its option, redeem all or a portion of the outstanding balance of the March 2026 Bridge Note (an “Optional Redemption”) upon written notice to YA, provided that the VWAP of the Company’s common stock at the time of such notice is less than the Fixed Price. The redemption price equals (i) the principal amount redeemed, (ii) a premium of 3 % of such principal amount, and (iii) any accrued and unpaid interest; provided that the premium does not apply to Optional Redemptions completed on or prior to April 30, 2026. Seller Note – related party On September 24, 2025, the Company issued a note payable to CPP (“Seller Note”) in connection with the Company’s acquisition of 100 % of the membership interests in Sunder and concluded that the Seller Note is a related party obligation (see Note 3 – Business Combinations ). The Seller Note has an original principal amount of $ 20.0 million. The Seller Note bears interest at 7.0 % per annum, compounded at the end of each calendar quarter. Interest is due and payable concurrent with the payment of the principal balance. The maturity date of the Seller Note was initially the earlier of (i) May 15, 2026 and (ii) the date on which all amounts under the Seller Note otherwise become due and payable following an event of default. The Seller Note must also be repaid in the event of a change of control of the Company or the sale of all or substantially all of the consolidated assets of the Company and its subsidiaries. The Seller Note includes customary events of default, including: (a) the Company’s failure to pay the Seller Note when due, (b) the Company’s voluntary or involuntary bankruptcy, (c) the Company’s liquidation or dissolution, (d) a change of control of the Company, (e) the Company’s material breach of the covenants applicable to the Company under the Seller Note, subject to applicable cure periods, and (f) if any of the Company’s representations or warranties made in the Seller Note were untrue in any material respect when made. Management concluded that the carrying value of the Seller Note approximates its fair value due to the short-term nature of the obligation. 28 On March 5, 2026, the Company entered into an amendment of the Seller Note (“Amendment”) providing that if the terms of the SEPA would restrict repayment of the Seller Note on May 15, 2026, then the maturity date of the Seller Note will be extended to the earlier of (a) the date that is two business days following the date on which the Seller Note may be repaid pursuant to the restrictions set forth in the SEPA Debenture and (b) September 30, 2026 (or, if the registration statement required to be filed pursuant to the Registration Rights Agreement has not been declared effective prior to April 30, 2026, then the outside maturity date will extend to December 31, 2026). Additionally, the Company and CPP agreed that the interest rate applicable to the Seller Note will increase to 10.0 % per annum if the principal amount of the Seller Note remains outstanding after May 15, 2026. As an inducement to CPP’s agreement to the foregoing, the Amendment also provides that, within two business days following approval by the Company’s stockholders of the issuance of shares under the Sunder MIPA in accordance with applicable Nasdaq rules, the Company will issue the remaining shares of common stock otherwise issuable to CPP pursuant to the Sunder MIPA. On April 8, 2026, the Company issued the remaining 6.7 million shares of the Company’s common stock due under the Seller Note.

Related party amortization expense was $ 0.5 million and $ 0.5 million in the thirteen week periods ended March 29, 2026 and March 30, 2025, respectively. September 2025 Notes On September 21, 2025, the Company issued an additional $ 22.0 million of the 7.0 % Notes (the “September 2025 Notes”) pursuant to the Indenture to various parties. The September 2025 Notes contain a conversion option which required bifurcation and recognition of a derivative, and the Company recorded a derivative liability of $ 15.4 million on the issuance date. The Company also recognized a $ 3.6 million debt discount and issuance costs in connection with the September 2025 Notes. The debt issuance costs include an estimate of the value of a warrant issued in the second quarter of fiscal 2026 to the entity that arranged the financing. The effective interest rate on the September 2025 Notes approximated 78 % as of March 29, 2026. The net proceeds from the issuance of the September 2025 Notes were principally used to pay a portion of the cash consideration for the Company’s acquisition of Sunder. The carrying amount of the September 2025 Notes, inclusive of the fair value of the derivative liabilities was as follows (in thousands) : As of March 29, December 28, 2026 2025 September 2024 Notes $ 22,000 $ 22,000 Less Unamortized debt discount ( 18,425 ) ( 18,646 ) Net carrying amount of September 2024 Notes $ 3,575 $ 3,354 In the thirteen week period ended March 29, 2026, total interest expense was $ 0.6 million with coupon interest expense of $ 0.4 million and debt discount and issuance costs of $ 0.2 million.

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 recorded within accrued expenses and other current liabilities on its consolidated balance sheets as of March 29, 2026, and December 28, 2025, respectively. 35 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 Court heard argument regarding the Company’s partial motion to dismiss on February 12, 2026. On April 8, 2026, the Court granted-in-part and denied-in-part the Company’s partial motion to dismiss. The Court denied the Company’s motion as to the breach of contract claim and granted the motion as to fraudulent inducement, tortious interference, and injunctive relief. The Court dismissed the tortious interference and injunctive relief claims with prejudice but granted SolarPark’s leave to amend its fraudulent inducement claim. On April 28, 2026, SolarPark filed a notice stating that it did not intend to amend its complaint to refile a fraudulent inducement claim. SolarPark now intends to proceed only on the surviving claims (misappropriation of trade secrets and breach of contract). On April 29, 2026, the Court set a case management conference for June 4, 2026, and a deadline for filing a joint case management statement by May 28, 2026. The Company intends to answer the complaint and file counterclaims. 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. 36 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 (collectively, the “Fundraise Provision”). 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 $ 1.1 million and $ 3.5 million of outstanding letters of credit as of March 29, 2026 and December 28, 2025, respectively. 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 in Note 2 – Summary of Significant Accounting Policies , the cash collateral in these restricted cash accounts was $ 1.1 million and $ 3.8 million at each of March 29, 2026 and December 28, 2025, respectively. 37 (12) Income Taxes The Company’s income tax expense for interim periods is computed using an estimated annual effective tax rate applied to year-to-date ordinary income or loss, adjusted for the tax effects of discrete items recognized in the period in which they occur. The Company recognized an income tax benefit of $ 0.6 million and nil in the thirteen week periods ended March 29, 2026, and March 30, 2025, respectively. The Company’s effective tax rate was 10.4 % and nil for the thirteen week periods ended March 29, 2026, and March 30, 2025, respectively. The effective tax rate for the thirteen week period ended March 29, 2026 differs from the U.S. statutory rate of 21.0 % primarily because of permanent differences due to fair value adjustments and the valuation allowance against most of the deferred tax assets. The effective tax rate for the thirteen week period ended March 30, 2025 differs from the U.S. statutory rate of 21.0 % primarily because of permanent differences due to fair value adjustments, share-based compensation related to stock options, non-deductible meals and entertainment, and state taxes. As a result of the Company’s history of net operating losses, the Company has provided a full valuation allowance against its deferred tax assets. During the thirteen week period ended March 29, 2026, the Company recorded a $ 0.8 million decrease in its valuation allowance primarily related to recognition of deferred tax liabilities in connection with the Cobalt acquisition. As of the thirteen week periods ended March 29, 2026 and March 30, 2025, the Company had no unrecognized tax benefits. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. (13) Common Stock and Common Stock Warrants 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 March 29, 2026. No preferred stock has been issued and none are outstanding as of March 29, 2026. 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. On January 11, 2026, the Company and White Lion entered into Amendment No. 3 (“Amendment No. 3”) to the White Lion SPA. Amendment No. 3 extends the commitment period under the White Lion SPA (the “Commitment Period”) to the earlier of December 31, 2027 and the date on which White Lion has purchased an aggregate number of shares of the Company’s common stock equal to the Commitment Amount (as defined below). Further, Amendment No. 3 increases, subject to approval by the Company’s stockholders, the commitment amount under the Purchase Agreement to $ 55.0 million of shares of its common stock (the “Commitment Amount”), which the Company may elect to sell to White Lion pursuant to the White Lion SPA, from time to time in the Company’s sole discretion, during the Commitment Period. 38 In addition, Amendment No. 3 adds an option for the Company to submit three hour rapid purchase notices to White Lion that, if accepted by White Lion and otherwise delivered in accordance with the Purchase Agreement, would enable the Company to sell shares of its common stock to White Lion based on the lowest traded price of the Company’s common stock during the three-hour valuation period following White Lion’s written acceptance of a three hour purchase notice. In the thirteen week period ended March 29, 2026, the Company issued an aggregate of 4.6 million shares of the Company’s common stock for total proceeds of $ 7.0 million. As of March 29, 2026, the Company has issued an aggregate of 11.5 million shares of the Company’s common stock for total proceeds of $ 20.4 million.

(18) Subsequent Events Cost Control Measures On May 12, 2026, the Company announced that it has taken the following steps in connection with its efforts to reduce its operating expenses: the Company implemented a reduction in force relating to 115 employees; the Company implemented an across-the-board, four-day workweek until September 2026, the Company reduced its inside sales group from 90 to 15 people, and the Company reduced finance function costs. The Company estimates that the charges related to the reduction in force will approximate $ 0.3 million, consisting principally of compensation related costs. Wendell Laidley Resignation On May 7, 2026, Wendell Laidley resigned from his position as Chief Financial Officer of the Company. Investor Deposit by a Related Party The Company received a deposit of $ 5.0 million (“Purchase Amount”) from the Rodgers Revocable Trust on March 27, 2026. On April 8, 2026, the Company entered into a SAFE (“Fourth SAFE”) with the Rodgers Revocable Trust in exchange for the $ 5.0 million received. The Fourth SAFE is automatically convertible into equity securities of the Company in an amount equal to the Purchase Amount divided by the applicable price per share, unit or other increment of the equity securities issued by the Company in its next equity financing transaction. Amendment to Seller Note As discussed in Note 9 – Borrowings and Derivative Liabilities, as an inducement to the Member’s agreement to the Amendment of the Seller Note, the Amendment also provides that, within two business days following approval by the Company’s stockholders of the issuance of shares under the Sunder MIPA in accordance with applicable Nasdaq rules, the Company will issue the remaining shares of common stock otherwise issuable to the Member pursuant to the Sunder MIPA. On April 8, 2026, the Company issued the remaining shares due under the Seller Note, 6.7 million shares of its common stock. Subsequent Convertible Senior Secured Notes Offering Subsequent to the quarter ended March 29, 2026, on April 21, 2026, the Company entered into note purchase agreements in connection with a private offering of $ 41.0 million aggregate principal amount of 10.0 % Convertible Senior Secured Notes due 2029 (the “ 10 % Senior Secured Notes”). The offering included (i) $ 25.0 million of 10.0 % Senior Secured Notes issued to institutional investors, (ii) $ 6.0 million of 10 % Senior Secured Notes issued to an affiliate of the Company’s Chief Executive Officer in exchange for amounts previously advanced under the Third SAFE and Fourth SAFE, and (iii) $ 10.0 million of 10.0 % Senior Secured Notes issued in connection with the exchange of the Seller Note and execution of the A&R Seller Note. The 10 % Senior Secured Notes mature on May 1, 2029 and bear interest at 10.00 % per annum, payable quarterly in arrears beginning July 1, 2026. The 10 % Senior Secured Notes are senior secured obligations of the Company and are fully and unconditionally guaranteed by a wholly owned subsidiary. The notes and guarantees are secured by first-priority liens on substantially all of the assets of the Company and the guarantor, subject to permitted liens and specified exceptions. The 10 % Senior Secured Notes are convertible at the option of the holders into shares of the Company’s common stock at an initial conversion price of approximately $ 1.64 per share ( 610.3143 shares of common stock per $ 1,000 principal amount of the 10 % Senior Secured Notes). In addition, following certain corporate events that occur prior to the maturity date of the 10 % Senior Secured Notes, the Company will, under certain circumstances, increase the conversion rate of the 10 % Senior Secured Notes for a holder who elects to convert its 10 % Senior Secured Notes in connection with such a corporate event, subject to a maximum conversion rate of $ 1.13 per share ( 884.9557 shares of the Company’s common stock per $ 1,000 principal amount of 10 % Senior Secured Notes). The 10 % Senior Secured Notes are not redeemable by the Company and include customary covenants, events of default, and change-of-control repurchase provisions. 44 The proceeds of the offering of the 10 % Senior Secured Notes were used to: (i) prepay $ 5.0 million principal amount of the March 2026 Bridge Note; (ii) pay $ 4.75 million pursuant to the Company’s settlement agreement with Siemens (as amended, the “Siemens Settlement”); (iii) pay $ 4.0 million to CPP in connection with the transactions under the CPP Note Purchase Agreement (as defined below); and (iv) pay approximately $ 1.5 million of fees and expenses incurred in connection with the Offering. The net proceeds of the Offering, after making the foregoing payments, were approximately $ 9.75 million. The Company intends to use the net proceeds of the Offering for working capital and general corporate purposes, including the payoff of the remaining outstanding balance of the YA Debenture. YA Letter Agreement On April 21, 2026, in connection with the offering of the 10 % Senior Secured Notes, the Company and YA entered into a letter agreement (the “YA Letter”). Pursuant to the YA Letter, the Company agreed to voluntary prepay $ 5.0 million of the outstanding principal amount of March 2026 Bridge Note, resulting in a revised outstanding principal balance under the March 2026 Bridge Note of $ 5.0 million. The Company further agreed to repay the remaining principal balance and accrued interest under the YA Debenture in four equal monthly installments of $ 1.287 million, with the first payment due on May 5, 2026. Pursuant to the YA Letter, YA further consented to the issuance of the 10 % Senior Secured Notes and the grant of the liens to secure the obligations under the 10 % Senior Secured Notes. CPP Note Purchase Agreement and A&R Seller Note Also on April 21, 2026, the Company entered into a Note Purchase Agreement with CPP (the “CPP Note Purchase Agreement”) that provides for the following in exchange for the outstanding Seller Note (in addition to the issuance of $ 10.0 million principal amount of 10 % Senior Secured Notes to CPP as summarized above): (i) the Company’s payment of $ 4.0 million in cash to CPP at the closing under the CPP Note Purchase Agreement and (ii) delivery of the A&R Seller Note. The A&R Seller Note has a revised principal balance of $ 7.0 million and bears interest at 7.0 % per annum, compounded quarterly, increasing to 10.0 % per annum beginning May 15, 2026. The A&R Seller Note is payable in four installments between October 2026 and January 2027, subject to extension if payment is restricted under the 10 % Senior Secured Notes. The A&R Seller Note is unsecured and contains customary events of default and change-of-control provisions. Amendment to Siemens Settlement On April 9, 2026, Siemens and the Company amended the Settlement Agreement. Among other changes, the key terms of the amendment included (i) SunPower’s commitment to pay $ 4.75 million of the $ 9.5 million settlement amount by the end of April 2026, (ii) changing the threshold of the Fundraise Provision from $ 1.0 million to $ 5.0 million; (iii) putting Siemens’ first-priority continuing security interest pari pasu with the similarly secured interests of the note holders of the 10 % Senior Secured Notes; and (iv) changing the acceleration amount in the Fundraise Provision from an acceleration of one remaining quarter to an acceleration of both remaining quarters. The Company made the $ 4.75 million April payment on April 23, 2026. Exchange of 7% Notes Also on April 21, 2026, the Company entered into privately negotiated exchange agreements with certain holders of its outstanding 7.0 % Notes due 2029. Pursuant to these agreements, $ 21.25 million principal amount of such notes was exchanged for an aggregate of 18.8 million shares of the Company’s common stock and approximately $ 0.46 million of cash for accrued interest. The exchanges are expected to reduce outstanding indebtedness and future cash interest obligations, but will increase the number of shares outstanding. Conversion of September 2024 Notes Subsequent to March 29, 2026 $ 1.0 million of the September 2024 Notes were converted by holders into approximately 0.6 million shares of the Company’s common stock. Delay in Filing of Form 10Q as of and for the thirteen week period ended March 29, 2025 As a result of not filing the March 29, 2026 Form 10-Q within the timeframe by May 18, 2026 as required by the SEC, an event of default occurred under the Yorkville Notes, which results in an increase in the applicable interest rate to 18 % (for so long as such event of default remains uncured). Upon filing this Form 10-Q on May 19, 2026 , the event of default was cured. 45 ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS You should read the following discussion and analysis of our financial condition and results of operations together with the unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on April 30, 2025, and related management’s discussion and analysis in Item 7 of the Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Please also see the section titled “Special Note Regarding Forward-Looking Statements.” Overview SunPower Inc. is a residential solar and energy services company headquartered in Orem, Utah. We operate a technology-enabled platform that supports a national network of sales partners, dealers, and installation professionals to deliver solar energy systems, battery storage solutions, and related services to homeowners and homebuilders throughout the United States. We fulfill our customer contracts by using in-house installation experts and by engaging with local construction specialists. We manage the customer experience and complete all pre-construction activities prior to delivering build-ready projects including hardware, engineering plans, and building permits to our builder partners. We manage and coordinate this process through our proprietary software system. During 2025 and through the thirteen week period ended March 29, 2026 we significantly reshaped our business through a series of strategic acquisitions, including the acquisition of Sunder Energy, LLC (“Sunder”), Ambia Energy LLC (“Ambia”) and Cobalt Power Systems, Inc. (“Cobalt”). These acquisitions expanded our geographic footprint, dealer network, installation capacity, and national sales presence. The operating results in the current quarter reflect the integration and ongoing operations of these acquired businesses. As further discussed below and in Note 16 – Segment Information to our unaudited condensed consolidated financial statements, we have three reportable segments: Residential Solar Installation, New Homes Business and Dealer. There is substantial doubt about our ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued. The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared assuming our Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business. They do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to our ability to continue as a going concern. Recent Developments Acquisitions We continued the integration of recent acquisitions of Sunder and Ambia into our operating platform. In the thirteen week period ended March 29, 2026, we acquired Cobalt for $9.7 million. Cobalt focuses on large premium renewable energy systems across residential, new home, multifamily and commercial projects and its operating results will be incorporated into the New Homes reportable segment. Critical accounting policies and estimates See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Estimates” and our consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 28, 2025 for accounting policies and related estimates we believe are the most critical to understanding our consolidated financial statements, financial condition and results of operations and which require complex management judgment and assumptions, or involve uncertainties. These critical accounting estimates are revenue recognition accounting and accounting for business combinations. There have been no changes to our critical accounting estimates or their application since the date of our Annual Report on Form 10-K for the fiscal year ended December 28, 2025. 46 Results of operations We have derived the following data from our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. This information should be read in conjunction with our unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. The results of historical periods are not necessarily indicative of the results of operations for any future period. Thirteen-weeks ended March 29, 2026 compared to the thirteen weeks ended March 30, 2025 The following table sets forth our unaudited statements of operations from operations for the thirteen weeks ended March 29, 2026, and March 30, 2025 ( in thousands ): Thirteen Weeks Ended (in thousands) March 29, 2026 March 30, 2025 $ Change % Change Revenues $ 72,793 $ 78,413 $ (5,620 ) (7 )% Cost of revenues 28,106 51,037 (22,931 ) (45 )% Gross (loss) profit 44,687 27,376 17,311 63 % Gross margin % 61 % 35 % Operating expenses: Sales commissions 28,564 7,684 20,880 272 % Sales and marketing 4,993 8,522 (3,529 ) (41 )% General and administrative 30,325 14,896 15,429 104 % Total operating expenses 63,882 31,102 32,780 105 % Loss from operations (19,195 ) (3,726 ) (15,469 ) 415 % Interest expense (1) (6,924 ) (6,041 ) (883 ) 15 % Interest income — 3 (3 ) (100 )% Other non-operating income, net (2) 30,761 14,576 16,185 111 % Income from operations before taxes 4,642 4,812 (170 ) (4 )% Income tax benefit 608 — 608 * Net income $ 5,250 $ 4,812 $ 438 9 % * Percentage change is not meaningful. (1) Includes interest expense and amortization of debt issuance costs to related party of $2.3 million and $1.4 million in the thirteen-weeks ended March 29, 2026 and March 30, 2025, respectively. (2) Includes the following gains and (losses) with related parties (in millions): Thirteen Weeks Ended March 29, 2026 March 30, 2025 Change in fair value of derivative liabilities $ 7.5 $ 3.7 Change in fair value of forward purchase agreement liabilities — 0.1 Other income, net — 0.1 Change in fair value of SAFE Agreement (0.2 ) — Change in fair value of Deferred Sunder Consideration 2.3 — 47 Revenues We disaggregate our revenues based on the following types of services (in thousands) : Thirteen Weeks Ended March 29, 2026 March 30, 2025 $ Change % Change Residential Solar Installation $ 31,541 $ 36,504 $ (4,963 ) (14 )% New Homes Business 14,625 41,909 (27,284 ) (65 )% Dealer 26,627 — 26,627 * Total revenues $ 72,793 $ 78,413 $ (5,620 ) (7 )% * Percentage change is not meaningful. The decrease in Residential Solar Installation was driven primarily by lower installation volumes, reflecting softer consumer demand due to higher interest rates as a result of an increase in financing costs for residential solar. In addition, the phase out of certain residential Investment Tax Credits (“ITCs”) passed in 2025 as part of the One Big Beautiful Bill in conjunction with fewer customers qualifying for financing makes it harder for a homeowner to make the decision quickly. The decrease also reflects fewer system activations as we continued to optimize our sales channels and focus on streamlining our operations to enhance its customer experience. New Homes Business revenues decreased primarily due to lower construction activity and selective solar integration volumes from homebuilder partners, due to higher interest rates and higher labor costs thus driving the overall costs of the home to increase. While regulatory requirements force investments in solar in certain regions and communities, the pace has slowed down due to affordability. In states and communities where regulatory requirements for new builds will not impact the demand of solar installation, homebuilders are not abandoning solar they are offering it as an option versus a spec home. Additionally, there was a backlog of jobs from the SunPower Businesses acquisition in 2024, for certain large homebuilder projects that contributed meaningfully to the prior-year quarter which did not recur in the current period as we are rebuilding our pipeline. We are also building this business which we acquired out of bankruptcy in 2024 as part of the SunPower Businesses acquisition. Dealer revenues and costs in the thirteen week period ended March 29, 2026 are attributable to the acquisition of Sunder on September 24, 2025. Cost of revenues and gross margins Thirteen Weeks Ended March 29, March 30, $ % 2026 2025 Change Change Residential Solar Installation $ 18,011 $ 22,615 $ (4,604 ) (20 )% New Homes Business 9,961 28,422 (18,461 ) (65 )% Dealer 134 — 134 * Total cost of revenues $ 28,106 $ 51,037 $ (22,931 ) (45 )% Gross margin 61 % 35 % * Percentage change is not meaningful. Residential Solar Installation cost of revenues decreased primarily attributable to lower installation activity resulting from softer consumer demand. Higher interest rates increased financing costs for homeowners, and the expiration of certain ITCs reduced the economic incentive to adopt residential solar. As a result, installation volumes declined, leading to lower associated material, labor, and subcontractor costs. New Homes Business cost of revenues decreased primarily driven by reduced solar installation option due to the demands of keeping home prices down demanded by home buyers. Homebuilders slowed construction primarily reducing optional features due to elevated mortgage rates, affordability pressures on buyers, and the reduced benefit of ITCs for solar-equipped new homes. 48 Sales commissions Thirteen Weeks Ended March 29, 2026 March 30, 2025 $ Change % Change Residential Solar Installation $ 6,553 $ 6,667 $ (114 ) (2 )% New Homes Business 1,166 1,017 149 15 % Dealer 20,845 — 20,845 * Total sales commissions $ 28,564 $ 7,684 $ 20,880 272 % * Percentage change is not meaningful. Residential Solar Installation sales commissions decreased slightly primarily due to lower residential installation volumes. Softer consumer demand driven by higher interest rates increased financing costs and the expiration of certain ITCs resulted in fewer closed sales, which reduced commissionable activity. New Homes Business sales commissions increased modestly due to changes in the mix of homebuilder programs and compensation structures, including higher per-unit commission rates on certain projects. Timing of community launches and sales cycles also contributed to the year-over-year variance. Sales and marketing Thirteen Weeks Ended March 29, 2026 March 30, 2025 $ Change % Change Residential Solar Installation $ 3,539 $ 8,522 $ (4,983 ) (58 )% New Homes Business 876 — 876 * Dealer 578 — 578 * Total sales and marketing $ 4,993 $ 8,522 $ (3,529 ) (41 )% * Percentage change is not meaningful. Residential Solar Installation sales and marketing expenses decreased reflecting reduced spending on lead generation, advertising, and promotional programs as we scaled back customer-acquisition efforts in response to softer demand. Higher interest rates increased financing costs for homeowners, and the expiration of certain ITCs reduced the economic incentive to adopt residential solar. As a result, we intentionally moderated marketing investments to align with lower sales volumes. In addition, we acquired Sunder a sales force organization. New Homes Business sales and marketing expenses had no comparable expenses in the prior-year period as the Company does not make significant investments in sales and marketing spend. 49 General and administrative Thirteen Weeks Ended March 29, 2026 March 30, 2025 $ Change % Change Residential Solar Installation $ 15,833 $ 10,440 $ 5,393 52 % New Homes Business 11,545 4,456 7,089 159 % Dealer 2,947 — 2,947 * Total general and administrative $ 30,325 $ 14,896 $ 15,429 104 % * Percentage change is not meaningful. Residential Solar Installation general and administrative expenses increased primarily due to higher employee-related expenses, including salaries, benefits, and stock-based compensation, as we continued to invest in operational infrastructure and administrative support functions. Additionally, higher insurance, facilities, and technology-related costs investments that focuses on scalability contributed to the period over period increase. New Homes Business general and administrative expenses increased primarily due to higher personnel costs and expanded administrative support for homebuilder programs, including project management, compliance, and operational oversight. We also incurred incremental technology, systems, and shared-services costs allocated to the New Homes segment as part of broader organizational growth. Dealer general and administrative expenses primarily relate to personnel, facilities, and administrative overhead associated with integrating and operating the Dealer business. Interest expense Interest expense in the thirteen-weeks ended March 29, 2026, consisted principally of $4.5 million attributable to our September 2024 Notes and $1.8 attributable to the July 2024 Notes. Interest expense in the thirteen-weeks ended March 30, 2025, consisted principally of $5.0 million of interest expense attributable to our September 2024 Notes and the remainder principally attributable to the July 2024 Notes. Other non-operating income, net Other non-operating income, net in the thirteen weeks ended March 29, 2026, was $30.8 million. The main drivers consist of $26.6 million gain on the remeasurement of the fair value of derivative liabilities associated with our 12% and 7% senior unsecured convertible notes and $5.2 million gain on the revaluation of deferred consideration, partially offset by a $1.1 million change in the fair value of our forward purchase agreements. Other income net, for the thirteen weeks ended March 30, 2025, was $14.6 million. The main drivers of Other non-operating income, net were $15.1 million of gains on the remeasurement of the fair value of derivative liabilities associated with our July 2024 Notes and September 2024 Notes, $0.3 million of income arising from the change in the fair value of our forward purchase agreements and $0.2 million of other income, partially offset by $1.1 million of expense associated with the change in the fair value of our public, private placement and working capital warrants which are accounted for as liabilities. Net income As a result of the factors discussed above, our net income for the thirteen-weeks ended March 29, 2026 was $5.25 million, a $0.4 million increase in our net income as compared to net income of $4.8 million for the thirteen weeks ended March 30, 2025. Liquidity and capital resources Overview Our operating loss was $19.2 million in the thirteen week period ended March 29, 2026. As of March 29, 2026, we had an accumulated deficit of $451.5 million, current debt of $38.0 million, and cash and cash equivalents (excluding restricted cash) of $9.5 million which was held for working capital expenditures. We believe our operating losses and negative operating cash flows will continue into the foreseeable future. 50 Material changes to our liquidity and capital resources since December 28, 2025 Amendment to White Lion Purchase Agreement On January 11, 2026, we and White Lion Capital, LLC (“White Lion”) entered into Amendment No. 3 (the “Amendment No. 3”) to the Common Stock Purchase Agreement, dated July 16, 2024, between the Company and White Lion, as previously amended by Amendment No. 1, effective July 24, 2024, and Amendment No. 2, effective August 14, 2024 (as amended, the “Purchase Agreement”). Amendment No. 3 extends the commitment period under the Purchase Agreement (the “Commitment Period”) to the earlier of December 31, 2027 and the date on which White Lion has purchased an aggregate number of shares of our common stock equal to the Commitment Amount (as defined below). Further, Amendment No. 3 increases, subject to approval by the Company’s stockholders, the commitment amount under the Purchase Agreement to $55.0 million of shares of its common stock (the “Commitment Amount”), which the Company may elect to sell to White Lion pursuant to the Purchase Agreement, from time to time in our sole discretion, during the Commitment Period. Lastly, Amendment No. 3 adds an option for the Company to submit three hour rapid purchase notices to White Lion that, if accepted by White Lion and otherwise delivered in accordance with the Purchase Agreement, would enable us to sell shares of our common stock to White Lion based on the lowest traded price of our common stock during the three-hour valuation period following White Lion’s written acceptance of a three hour purchase notice. Standby Equity Purchase Agreement and $1.9 Million Note On January 27, 2026, we entered into a Standby Equity Purchase Agreement (the “SEPA”) with YA II PN, LTD. (“YA”). Under the SEPA, YA agreed to advance up to $20.0 million (the “Prepaid Advances”) to us in the form of convertible promissory notes. (each, a “Promissory Note”), subject to the terms and conditions of the SEPA. As discussed below, we received an initial Pre-Paid Advance of $1.9 million, and the Company’s rights to further Pre-Paid Advances terminated pursuant to the terms of the SEPA. The Pre-Paid Advance under the Promissory Notes accrue interest at 0% per annum, increasing to 18% per annum upon the occurrence of an event of default. The Pre-Paid Advance that we received was funded at a 10% original issue discount. In addition, the SEPA provides us with the right, but not the obligation, to require YA to purchase up to $25.0 million (“Commitment Amount”) of our common stock through January 27, 2029, subject to customary limitations and conditions, including trading volume and ownership limitations. The SEPA will automatically terminate on the earliest to occur of (i) January 27, 2029 or (ii) the date on which YA has purchased from us under the SEPA the Commitment Amount in full. We may terminate the SEPA at any time upon five trading days’ prior written notice to YA, provided that there are no outstanding advance notices under which we have yet to issue shares of our common stock, there are no amounts outstanding under any promissory notes, and provided that we have paid all amounts owed to YA pursuant to the SEPA. We and YA may also agree to terminate the SEPA by mutual written consent. We view the SEPA as a flexible source of potential liquidity; however, the issuance of equity under the SEPA could result in dilution to existing stockholders, and the availability of proceeds is subject to market conditions and compliance with the agreement’s terms. In connection with the execution of the SEPA, we paid YA a due diligence, structuring and commitment fee totaling $0.4 million which consisted of $0.05 million cash and 175,000 shares of common stock. On January 27, 2026 the first Pre-Paid Advance was disbursed. The gross amount of the borrowing under the Pre-Paid Advance was $1.9 million, which was advanced under a Promissory Note (“$1.9 Million Note”), for net proceeds received totaling $1.7 million after the contractual discount. The $1.9 Million Note matures on January 27, 2027, subject to extension at YA’s option, and is convertible into shares of our common stock. March 2026 Bridge Note On March 6, 2026, we entered into a purchase agreement with YA pursuant to which we issued a convertible debenture in the principal amount of $10.0 million (the “March 2026 Bridge Note”) for net proceeds of approximately $9.0 million, after fees. The March 2026 Bridge Note bears interest at 0% per annum, increasing to 18% per annum upon the occurrence of an event of default, and matures on March 6, 2027, subject to extension at YA’s option. Beginning on May 6, 2026, we are required to make monthly installment payments through September 6, 2026, each consisting of $2.0 million of principal, a payment premium of $0.06 million, and any accrued interest. Each installment may be satisfied, at the Company’s option, in cash, through the issuance of shares pursuant to an advance notice under the SEPA, or through a combination of both. The terms of the March 2026 Bridge Note were subsequently amended as summarized below. 51 The March 2026 Bridge Note is convertible into shares of our common stock at the option of YA. Outstanding balances may be converted at an adjusted fixed price of $1.64 per share, or, with respect to amounts due and unpaid on or after an installment date, at a variable price based on a percentage of our stock’s recent trading prices, subject to a floor price. The March 2026 Bridge Note also permits us, under certain conditions, to redeem amounts outstanding prior to maturity, which may require the payment of a premium depending on the timing of such redemption. At any time after issuance, YA may convert all or a portion of the outstanding principal balance into shares of the Company’s common stock at an adjusted fixed conversion price of $1.64 per share (the “Fixed Price”). In addition, any Installment Amount that remains unpaid following an Installment Date may be converted at a price equal to 95% of the volume weighted average price (“VWAP”) of the Company’s common stock during the five trading days immediately preceding the conversion date, subject to a minimum conversion price equal to the then-applicable floor price. The Company may, at its option, redeem all or a portion of the outstanding balance of the March 2026 Bridge Note (an “Optional Redemption”) upon written notice to YA, provided that the VWAP of the Company’s common stock at the time of such notice is less than the Fixed Price. The redemption price equals (i) the principal amount redeemed, (ii) a premium of 3% of such principal amount, and (iii) any accrued and unpaid interest; provided that the premium does not apply to Optional Redemptions completed on or prior to April 30, 2026. Financing transactions subsequent to March 29, 2026 Subsequent to the quarter ended March 29, 2026, we completed several significant financing and capital restructuring transactions. On April 21, 2026, we completed a private offering (“Private Offering”) of $41.0 million aggregate principal amount of 10.0% Convertible Senior Secured Notes due 2029 (the “10% Senior Secured Notes”). The Private Offering included (i) $25.0 million of notes issued to institutional investors, (ii) $6.0 million of notes issued to an affiliate of our CEO in exchange for amounts previously advanced under the Third SAFE and Fourth SAFE (refer to Note 8 – SAFE Agreement and Note 18 – Subsequent Events for details of the SAFE Agreements) and (iii) $10.0 million of notes issued in connection with the exchange of the Seller Note (as described below). Net proceeds from the Private Offering, after payment of transaction fees and expenses and the settlement of certain obligations, were approximately $9.8 million. We used a portion of the gross proceeds from the offering to (i) prepay $5.0 million of the March 2026 Bridge Note, (ii) satisfy payment obligations under an amended settlement agreement with Siemens totaling $4.75 million, (iii) make a $4.0 million cash payment to CPP Note Purchase Agreement (as defined below); and (iv) pay approximately $1.5 million of fees and expenses incurred in connection with the private offering. The remaining proceeds are expected to be used for working capital and general corporate purposes, including repayment of the remaining balance under the March 2026 Bridge Note. On April 21, 2026, in connection with the Private Offering, we and YA entered into a letter agreement (the “YA Letter”). Pursuant to the YA Letter, we agreed to voluntary prepay $5.0 million of the outstanding principal amount of March 2026 Bridge Note, resulting in a revised outstanding principal balance under the March 2026 Bridge Note of $5.0 million. We further agreed to repay the remaining principal balance and accrued interest under the March 2026 Bridge Note in four equal monthly installments of $1.287 million, with the first payment due on May 5, 2026. Pursuant to the YA Letter, YA further consented to the issuance of the 10% Senior Secured Notes and the grant of the liens to secure the obligations under the 10% Senior Secured Notes. Also on April 21, 2026, we entered into a Note Purchase Agreement with CPP (the “CPP Note Purchase Agreement”) that provides for the following in exchange for the outstanding Seller Note (in addition to the issuance of $10.0 million principal amount of 10% Senior Secured Notes to CPP as summarized above): (i) we made a $4.0 million payment in cash to CPP at the closing under the CPP Note Purchase Agreement and (ii) amended and restated the outstanding Seller Note as further summarized below. In connection with the 10% Senior Secured Notes offering, we amended and restated the Seller Note (“A&R Seller Note”). The A&R Seller Note has a revised principal balance of $7.0 million and bears interest at 7.0% per annum, compounded quarterly, increasing to 10.0% per annum beginning May 15, 2026. The A&R Seller Note is payable in four installments between October 2026 and January 2027, subject to extension if payment is restricted under the 10% Senior Secured Notes. The A&R Seller Note is unsecured and contains customary events of default and change-of-control provisions. Additionally, on April 21, 2026, we entered into privately negotiated exchange agreements with certain holders of our 7.0% Notes due 2029, pursuant to which $21.25 million of the principal amount of such notes was exchanged for shares of our common stock and cash for accrued interest, thereby reducing outstanding indebtedness and future cash interest obligations. 52 Liquidity Outlook We continue to evaluate additional financing opportunities and capital management strategies to support our operating needs and strategic objectives. Our primary sources of liquidity consist of existing cash balances, cash flows from operations, and access to capital under new and existing financing arrangements. We expect that installment payments under the current obligations will require the use of available cash, equity issuance, or a combination thereof. As a result, our liquidity and capital resources will continue to depend on operating performance, capital market conditions, and our ability to access equity financing arrangements. Cash flows for the thirteen weeks ended March 29, 2026 and March 30, 2025 The following table summarizes our cash flows from operating, investing, and financing activities for the thirteen week periods ended March 29, 2026 and March 30, 2025 (in thousands) : Thirteen Weeks Ended March 29, 2026 March 30 2025 Net cash used in operating activities $ (25,656 ) $ (2,627 ) Net cash used in investing activities 553 — Net cash provided by financing activities 22,267 (198 ) Net decrease in cash, cash equivalents and restricted cash (2,836 ) (2,825 ) Cash flows from operating activities Net cash used in operating activities was $25.6 million in the thirteen weeks ended March 29, 2026. Net income of $4.1 million was offset by unfavorable non-cash adjustments of $22.0 million and an $8.9 million net cash outflow of operating assets and liabilities. Unfavorable non-cash adjustments consisted principally of a $26.6 million change in the fair value of derivative liabilities, $5.2 million unfavorable change in the fair value of the deferred consideration $0.6 million deferred tax benefit, and $0.6 million change in the fair value of warrants, partially offset by a $3.7 million of amortization of debt issuance costs, $3.6 million of depreciation and amortization, $1.6 million of stock-based compensation expense, $1.1 million change in the fair value of forward purchase agreements, $0.5 million of non-cash lease expense and net other adjustments of $0.5 million. Net cash outflows from changes in operating assets and liabilities principally consisted of a $12.9 million decrease in contract liabilities, $10.9 million increase in prepaid expenses and other assets and a $1.8 million decrease in accounts payable, partially offset by a $9.7 million increase in accrued expenses and other current liabilities, $5.0 million decrease in accounts receivable and a $2.0 million decrease in inventories. Net cash used in operating activities of $2.7 million in the thirteen weeks ended March 30, 2025, was due to net income of $4.8 million offset by $7.4 million of unfavorable noncash adjustments and $0.1 million of cash outflow from changes in operating assets and liabilities. Non-cash adjustments consisted principally of $15.1 million arising from remeasurement of derivative liabilities, partially offset by $3.7 million of amortization of debt issuance costs, $1.6 million of depreciation and amortization, $1.1 million provision for credit losses, $1.1 million due to the change in the fair value of warrants classified as liabilities, and $0.5 million of stock-based compensation. Cash outflows from changes in operating assets consisted principally of $11.3 million increase in contract assets, $4.4 million increase in prepaid expenses and other current assets, a $5.2 million decrease in accrued expenses and other liabilities, and a $0.4 million decrease in current operating lease liabilities almost entirely offset by an $11.4 million decrease in inventories, a $6.9 million increase in accounts payable and a $3.1 million decrease in contract liabilities. Cash flows from investing activities Net cash inflow of $0.5 million from investing activities in the thirteen week period ended March 29, 2026 is attributable to the cash acquired in the acquisition of Cobalt. Cobalt was acquired in exchange for shares of our common stock. Net cash used in investing activities was zero in the thirteen-weeks ended March 30, 2025. 53 Cash flows from financing activities Net cash provided by financing activities from continuing operations was $22.2 million for the thirteen weeks ended March 29, 2026 and consisted principally of $10.7 million in proceeds from the issuance of short-term debt, $1.3 million in proceeds from a related party in exchange for the issuance of 12% senior unsecured convertible notes, $7.0 million of proceeds from the issuance of our common stock and a related party investor deposit of $5.0 million partially offset by $1.1 million in principal payments on our 12% senior unsecured convertible notes and $0.7 million of finance lease payments. Net cash used in financing activities was $0.2 million for the thirteen weeks ended March 30, 2025, and consisted of $0.5 million of payments on our finance leases partially offset by $0.2 million in proceeds from the issuance of September 2024 Notes, and $0.1 million in proceeds from the exercise of stock options and warrants in exchange for the issuance of shares of our common stock. Emerging growth company status Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, and any such election to not take advantage of the extended transition period is irrevocable. SunPower is an “emerging growth company” as defined in Section 2(a) of the Securities Act and has elected to take advantage of the benefits of the extended transition period for new or revised financial accounting standards. Following the closing of the Mergers, our Post-Combination Company remains an emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of common stock that is held by non-affiliates exceeds $700 million as of the end of that year’s second fiscal quarter, (ii) the last day of the fiscal year in which we has total annual gross revenue of $1.235 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which we have issued more than $1.0 billion in non-convertible debt in the prior three-year period, or (iv) the last day of the fiscal year ending after the fifth anniversary of our IPO. SunPower expects to continue to take advantage of the benefits of the extended transition period, although it may decide to early adopt such new or revised accounting standards to the extent permitted by such standards. This may make it difficult or impossible to compare our financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Not applicable. ITEM 4. CONTROLS AND PROCEDURES Evaluation of disclosure controls and procedures As of the end of the period covered by this Quarterly Report on Form 10-Q, we conducted an evaluation, under the supervision and with the participation of our Chief Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based on this evaluation, our Chief Executive Officer and Principal Financial Officer concluded that, as of March 29, 2026, such disclosure controls and procedures were not effective as a result of previously reported material weaknesses. Notwithstanding the foregoing, there were no changes to previously issued financial statements. Our Chief Executive Officer and Chief Financial Officer believe that the interim unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial condition, results of operations and cash flows as of and for the periods presented in accordance with U.S. GAAP. 54 A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses are as follows: The Company did not maintain controls to execute the criteria established in the COSO Framework for (i) the control environment, (ii) risk assessment, (iii) control activities, (iv) information and communication, and (v) monitoring activities. Each of the control deficiencies identified below constitute a material weakness, either individually or in the aggregate. Control Environment. Our Company did not maintain an effective control environment and identified the following material weakness: our Company lacked appropriate policies and resources to develop and operate effective internal control over financial reporting and a lack of appropriate and consistent IT policies given the significant volume of financially relevant IT changes, which contributed to our Company’s inability to properly analyze, record and disclose accounting matters timely and accurately. Control Activities. Our Company did not design and implement effective control activities and identified the following material weakness: ● Ineffective design and operation of certain control activities due to significant personnel changes throughout 2025. Control deficiencies, which aggregate to a material weakness, occurred within substantially all areas of financial reporting. Information and Communication. Our Company did not design and implement effective information and communication activities and identified the following material weaknesses: ● Our Company did not design and maintain effective general information technology controls over logical access and program change management for our key information systems used to support the financial reporting process. Specifically, management did not maintain effective controls to ensure proper segregation of duties related to user administration and other privileged access functions and in implementing program changes in information systems. Due to the pervasive nature of these deficiencies, business process controls that are dependent upon information from these systems were also not effective. ● Our Company did not have adequate processes and controls for communicating information among the accounting, finance, operations, and legal departments, necessary to support the proper functioning of internal controls. Monitoring Activities. Our Company did not design and implement effective monitoring activities and identified the following material weaknesses: (i) failure to adequately monitor compliance with accounting policies, procedures and controls related to substantially all areas of financial reporting; and (ii) failure to properly select, develop and perform ongoing evaluations of the components of internal controls (including the monitoring of service providers’ control environments). Remediation Plan and Status Our Company is committed to remediating the material weaknesses identified above, fostering continuous improvement in internal controls and enhancing the effectiveness of our overall internal control environment. Since identifying the above material weaknesses, we have begun the process of implementing the remediation activities described below. We believe that these activities, when fully implemented, should remediate the identified material weaknesses and strengthen our internal control over financial reporting. These remediation efforts remain ongoing, and additional remediation initiatives may be necessary. 55 A material weakness cannot be considered completely remediated until the applicable controls have operated for a sufficient period of time such that management can conclude, through testing, that the controls are operating effectively. If not remediated, material weaknesses or control deficiencies could result in material misstatements. Accordingly, as management continues to monitor the effectiveness of our internal control over financial reporting, we will continue to perform additional procedures prescribed by management, including the use of certain manual mitigating control procedures and the employment of additional tools and resources deemed necessary, to ensure that our future consolidated financial statements are fairly stated in all material respects. The following planned remediation activities highlight our commitment to remediating the identified material weaknesses: ● Hire finance and accounting professionals with the appropriate level of experience and training necessary to develop, maintain and improve our accounting policies, procedures and internal controls, utilize third-party consultants and internal audit professionals to enhance the control environment, and continue to hire other qualified finance and accounting professionals. ● Provide, and continue to provide, training for employees regarding their responsibilities related to the performance or oversight of internal controls. ● Reinforce the importance of communication between the operations, accounting, and legal departments regarding key terms of, and changes or modifications to, customer, debt, equity, legal and other contracts by establishing controls requiring finance department approval of certain non-standard terms and agreements. ● Begin the implementation of a process to reevaluate, revise and improve our Sarbanes-Oxley compliance program, including governance, risk assessment, testing methodologies and corrective action. We plan to enhance our risk assessment procedures and conduct a comprehensive risk assessment. ● Develop, and continue to develop, internal control documentation over financial processes and related disclosures. We plan to continue to design and implement control activities to mitigate risks identified and test the operating effectiveness of such controls. If we are not able to maintain effective internal control over financial reporting and Disclosure Controls, or if material weaknesses are discovered in future periods, a risk that is significantly increased in light of the complexity of our business, we may be unable to accurately and timely report our financial position, results of operations, cash flows or key operating metrics, which could result in late filings of our annual and quarterly reports under the Exchange Act, restatements of financial statements or other corrective disclosures, an inability to access commercial lending markets, defaults under our credit agreements and other agreements, or other material adverse effects on our business, reputation, results of operations, financial condition or liquidity. Limitations on effectiveness of controls and procedures We do not expect that our Disclosure Controls will prevent all errors and all instances of fraud. Disclosure Controls, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the Disclosure Controls are met. Further, the design of Disclosure Controls must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all Disclosure Controls, no evaluation of Disclosure Controls can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of Disclosure Controls also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Changes in internal control over financial reporting Other than the material weaknesses and remediation efforts described above, there were no changes in our internal control over financial reporting during the first quarter that have materially affected, would have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 56 PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS The information with respect to legal proceedings is set forth under Note 11 – Commitments and Contingencies , in the accompanying unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q, and is incorporated herein by reference. ITEM 1A. RISK FACTORS We are subject to a number of risks that if realized could adversely affect our business, strategies, prospects, financial condition, results of operations and cash flows. As a result of the Private Placement, we are subject to the additional risks and uncertainties summarized below. In addition to the risk factors set forth below and the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors set forth in Item 1A. “Risk Factors” in our Annual Report on Form 10-K filed on April 14, 2026. Please carefully consider all of the information in this Quarterly Report and our Annual Report on Form 10-K filed on April 14, 2026, and the disclosures in this Quarterly Report included in Note 1 – Organization – Liquidity and going concern – of the notes to the financial statements contained in this Quarterly Report and “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and capital resources” section of this Quarterly Report) and in our other filings with the Securities and Exchange Commission before making an investment decision regarding us. Our 10.0% Notes are secured obligations, and there are risks associated with our 10.0% Notes that could adversely affect our business and financial condition.* On April 21, 2026, the Company entered into note purchase agreements in connection with a private offering of $41.0 million aggregate principal amount of 10.0% Notes. The indenture for the 10.0% Notes (the “Indenture”) includes customary covenants and sets forth certain events of default after which the 10.0% Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the Notes become automatically due and payable, which include the following: ● certain payment defaults on the 10.0% Notes (which, in the case of a default in the payment of interest on the Notes, will be subject to a 30-day cure period); ● failure by the Company to comply with its obligation to convert the 10.0% Notes in accordance with the Indenture upon exercise of a holder’s conversion right; ● the Company’s failure to send certain notices under the Indenture within specified periods of time; ● the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; ● a default by the Company in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; ● certain defaults by the Company or any of its significant subsidiaries with respect to (y) the liens securing the Company’s payment obligations under Siemens Settlement, or (z) indebtedness for borrowed money of at least $10.0 million; ● certain events of bankruptcy, insolvency or reorganization of the Company or any of the Company’s significant subsidiaries; ● a final judgment or judgments for the payment of $10.0 million (or its foreign currency equivalent) or more (excluding any amounts covered by insurance) in the aggregate rendered against the Company or any significant subsidiary, which judgment is not discharged, bonded, paid, waived or stayed within 60 days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished; 57 ● any security interest and liens purported to be created by any collateral document, including the Security Agreement (as defined below), shall cease to be in full force and effect or shall cease to give the collateral agent, for the benefit of the holders of the 10.0% Notes, the liens, rights, powers and privileges purported to be created and granted under such collateral documents, subject to certain exceptions; and ● a guarantee with respect to the 10.0% Notes ceases to be in full force and effect or the Company or any guarantor denies or disaffirms its obligations under the Indenture or any guarantee with respect to the 10.0% Notes. If certain bankruptcy and insolvency-related events of default occur with respect to the Company, the principal of, and accrued and unpaid interest, if any, on, all of the 10.0% Notes then outstanding shall automatically become due and payable. Our ability to remain in compliance with the covenants under the 10.0% Notes depends on, among other things, our operating performance, competitive developments, financial market conditions and stock exchange listing of our common stock, all of which are significantly affected by financial, business, economic and other factors. We are not able to control many of these factors. Accordingly, our cash flow may not be sufficient to allow us to make required payments under the 10.0% Notes or meet our other obligations thereunder. If we are not able to satisfy our obligations under the 10.0% Notes, including compliance with the affirmative, negative and financial covenants applicable to the Company, or if there are events of defaults under the 10% Senior Secured Notes, the holders will have the right to foreclose on their first priority security interest relating to substantially all of our assets to the exclusion of our general unsecured creditors. If the holders of the 10% Senior Secured Notes pursue foreclosure, any such foreclosure would have a material and adverse impact on our business. ITEM 2.
