On September 12, 2022, Total and Total Gaz sold to GIP III Sol Acquisition, LLC (“GIP Sol”) 50% less one unit of the equity interests in a newly formed Delaware limited liability company, Sol Holding, LLC (“HoldCo”), which is now the record holder of all of the shares of SunPower common stock (see Note 2. Transactions with Total and TotalEnergies SE ). Liquidity We currently anticipate that our cash and cash equivalents will be sufficient to meet our obligations over the next 12 months from the date of issuance of our financial statements. We continuously evaluate our liquidity and capital resources, including our access to external capital, to help ensure we can finance our future capital requirements. Basis of Presentation and Preparation Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles in the United States (“United States” or “U.S.,” and such accounting principles, “U.S. GAAP”) for interim financial information, and include the accounts of SunPower, all of our subsidiaries and special purpose entities, as appropriate under U.S. GAAP. All intercompany transactions and balances have been eliminated in consolidation. The financial information included herein is unaudited, and reflects all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the results for the periods presented. The January 1, 2023 consolidated balance sheet data was derived from SunPower’s audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended January 1, 2023, as filed with the Securities and Exchange Commission (“SEC”) on March 10, 2023, but does not include all disclosures required by U.S. GAAP. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in SunPower's Annual Report on Form 10-K for the fiscal year ended January 1, 2023. The operating results for the three and six months ended July 2, 2023 are not necessarily indicative of the results that may be expected for fiscal year 2023, or for any other future period. We have a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both the current fiscal year, fiscal 2023, and prior fiscal year, fiscal 2022, are 52-week fiscal years. The second quarter of fiscal 2023 ended on July 2, 2023, while the second quarter of fiscal 2022 ended on July 3, 2022. Management Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosures of contingent assets and liabilities reported in these condensed consolidated financial statements and accompanying notes. We base our estimates on historical experience and various other assumptions believed to be reasonable. Our actual financial results could materially differ from those estimates. Significant estimates in these condensed consolidated financial statements include revenue recognition, specifically nature and timing of satisfaction of performance obligations, standalone selling price of performance obligations, and variable consideration; credit losses, including estimating macroeconomic factors affecting historical recovery rate of receivables; inventory write-downs; long-lived assets and goodwill impairment, specifically estimates for valuation assumptions including discount rates and future cash flows; fair value of investments, including equity investments for which we apply the fair value option and other financial instruments; actuarial estimates related to our self-insured health benefits; valuation of goodwill and intangible assets acquired in a business combination; valuation of contingent consideration in a business combination; valuation of contingencies such as warranty and litigation; the incremental borrowing rate used in discounting of lease liabilities; the fair value of indemnities provided to customers and other parties; and income taxes and tax valuation allowances. Presentation and disclosure corrections We determined that certain charges related to indemnifications on warranty obligations and legal costs we have retained in connection with the sale of our C&I Solutions business to TotalEnergies Renewables should have been classified as discontinued operations instead of continuing operations in the condensed consolidated statements of operations. For the three months ended April 2, 2023, warranty claims of $6.8 million, and legal costs of $0.5 million, previously included in the financial statement line items “total cost of revenues” and “sales, general, and administrative expense”, respectively, should be included in the line item “net (loss) income from discontinued operations.” Accordingly, the prior presentation for the three months ended April 2, 2023 has been corrected in the six months ended July 2, 2023. The correction has no effect on “net (loss) income attributable to stockholders,” the condensed consolidated balance sheets, the condensed consolidated statements of equity, or the condensed consolidated statements of cash flows. Segment Information We operate in a single operating segment, providing solar power systems and services to residential customers. While our chief executive officer, as the chief operating decision maker (“CODM”), reviews financial information by different functions and revenue streams, he considers the business on a consolidated basis for purposes of allocating resources and reviewing overall business performance. Summary of Selected Significant Accounting Policies The following significant accounting policies are updates to our significant accounting policies from our Annual Report on Form 10-K for the fiscal year ended January 1, 2023. Refer to our Annual Report on Form 10-K for the fiscal year ended January 1, 2023 for the full list of our significant accounting policies. There have been no material changes or updates to our significant accounting policies disclosed in the Form 10-K except as updated below. Revenue Recognition We recognize revenue from contracts with customers when we have completed our performance obligations under an identified contract. The revenue is recognized in an amount that reflects the consideration for the corresponding performance obligations for the goods and services transferred. Solar Power Systems and Component Sales A majority of our revenue is generated by sales of fully functioning solar power systems to our customers. We sell our products through a network of installing and non-installing dealers and resellers, as well as our internal sales team. Usually, our performance obligation is to design and install a fully functioning solar energy system. We recognize revenue when the solar power system is fully installed and the final permit is received from the authority having jurisdiction, as we deem our performance obligation under the contract to be complete at such time, and the customer retains all of the significant risks and rewards of ownership of the solar power system. In situations when we are not responsible for construction and installation of solar power systems, usually when the sales are made by one of our installing dealers or resellers, we recognize revenue when the components of the solar power system are delivered at the customer site. All costs to obtain and fulfill contracts associated with system sales are expensed as a cost of revenue when we have fulfilled our performance obligations. Revenue is generally recognized at transaction price, net of costs of financing, or other consideration paid to the customers that is not in exchange for a distinct good or service. Also, our arrangements may contain clauses that can either increase or decrease the transaction price. Variable consideration is estimated at each measurement date at its most likely amount to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur and true-ups are applied prospectively as such estimates change. We also provide solar power systems to our customers in the form of 20-year lease agreements which are entered into by the customer with our third-party leasing partners. These third-party leasing partners are special-purpose entities that we do not control or consolidate. We recognize revenue when the system is fully installed, when permit to operate is given by the local utility company, and the solar system has produced meterable quantities of electricity, as we deem our performance obligation under the contract to be complete at such time. Transfers of financial assets In April 2023, to support the expansion of our residential solar and storage loan funding capacity, we entered into a series of agreements to sell solar loan receivables to a special-purpose entity in our existing joint venture, SunStrong, with Hannon Armstrong Sustainable Infrastructure Capital, Inc. (“HASI”). Under the agreements, we have secured financing commitments to fund more than $450.0 million for our residential solar and storage loan program, including a $300.0 million revolving credit facility from Credit Agricole Corporate & Investment Bank (“CA-CIB”). The CA-CIB credit revolver serves as a warehouse facility for SunStrong to temporarily finance solar assets prior to arranging long-term financings, such as asset-backed securities. The revolving warehouse facility will allow SunStrong to fund the acquisition of solar loans entered into by SunPower Financial's customers and issue asset-backed securities on an ongoing basis. In May 2023, to further support the expansion of our residential solar and storage loan funding capacity, we also entered into a series of agreements to sell solar loan receivables to a newly created special-purpose trust beneficially owned by one or more affiliates of KKR Credit Advisors (US) LLC (“KKR Credit”). Under the agreements, we have secured financing commitments to fund up to $550.0 million for our residential solar and storage loan program over a 15-month term, with annual renewal options. These agreements to sell solar loan receivables to third-parties are accounted for in accordance with ASC 860 , Transfers and Servicing . We make judgments, based in part, on supporting legal opinions, on whether these entities should be consolidated as a variable interest entity, as defined in ASC 810, Consolidation , and whether the transfers to these entities are accounted for as a sale of a financial asset or a secured borrowing under ASC 860 (see Note 9. Equity Investments for a discussion of our conclusion under ASC 810). Under ASC 860, for our loan receivables that are held for sale and the transfer of the financial assets to be considered a sale, the asset must be legally isolated from the transferor and the transferee must have actual and effective control of the asset. When the sale criteria are met, we, as the transferor, derecognize the lower of cost or fair value of the financial asset transferred and recognize a net gain or loss on the sale based on the excess of the proceeds received (less any transaction costs) over the carrying value or fair value. We do not retain actual or effective control in the transferred loan receivables, and therefore, the transfers are accounted for as a sale with the gain or loss from the sales included in our condensed consolidated statements of operations. The gain or loss, and cash proceeds, related to the sales of the financial assets are classified as operating activities in our condensed consolidated statements of cash flows. Our loan receivables are held for sale and recorded at carrying value when purchased, equal to the purchase price plus fees incurred. We subsequently measure our loan receivables held for sale at the lower of cost or fair value on an aggregate portfolio basis until the loan receivables are sold. Our loan receivables held for sale are typically sold within 30 days of origination. If the purchased loans do not meet the eligibility criteria to be sold, the loan receivables are transferred to held to maturity and included at amortized cost within “accounts receivable, net” and “other long-term assets” on our condensed consolidated balance sheets. These loan receivable agreements held to maturity have a term of typically 20 - 25 years and relate to loans that our customers enter into to pay for their solar power systems.

Related Party Transactions [Abstract]
Transactions With Total and Total Energies SE	TRANSACTIONS WITH TOTAL AND TOTALENERGIES SE In June 2011, Total completed a cash tender offer to acquire 60% of our then outstanding shares of common stock at a price of $23.25 per share, for a total cost of approximately $1.4 billion. In December 2011, we entered into a Private Placement Agreement with Total, under which Total purchased, and we issued and sold, 18.6 million shares of our common stock for a purchase price of $8.80 per share, thereby increasing Total's ownership to approximately 66% of our outstanding common stock as of that date. On May 24, 2022, Total and Total Gaz (collectively, “Sellers”) agreed to sell 50% less one unit of the equity interests in HoldCo, which upon closing of such transaction would be the record holder of all of the shares of our common stock held by Sellers, to GIP Sol (and such transaction, the “Transaction”). On September 12, 2022, Sellers closed the Transaction. In connection with the completion of the Transaction, TotalEnergies Renewables, GIP Sol, and HoldCo entered into a Letter Agreement, dated September 12, 2022, concerning certain governance rights with respect to HoldCo and the shares of our common stock held directly by HoldCo. Specifically, TotalEnergies Renewables and GIP Sol agreed to, among other things, take all actions necessary to cause HoldCo to designate and elect to our board of directors (the “Board”) such individuals as HoldCo is entitled to appoint pursuant to the Affiliation Agreement; provided, however, that for so long as HoldCo is entitled to appoint at least five directors to our Board, GIP Sol shall have the right to appoint two of such five directors. The Letter Agreement also contained certain provisions on voting and on the transfer of HoldCo interests and common stock of the Company. As of July 2, 2023, ownership of our outstanding common stock by TotalEnergies SE and its affiliates, and GIP Sol, was 50.2%. Sale of C&I Solutions Business On May 31, 2022, pursuant to the terms of the Definitive Agreement we signed with TotalEnergies Renewables on February 6, 2022, TotalEnergies Renewables acquired all of the issued and outstanding common stock of our C&I Solutions business. The preliminary purchase price of $190.0 million was subject to certain adjustments, including cash, indebtedness, and an estimated closing date working capital adjustment. Upon closing, we received net cash consideration of $149.2 million based on the estimated net assets of the business on that date. As of the third quarter of fiscal 2022, we recorded a payable of $7.0 million to Total, based on our review of the closing date working capital and our submission of the closing statement. On October 25, 2022, we received a notice of disagreement from TotalEnergies Renewables with respect to the closing statement. As set forth in the Definitive Agreement, we appointed an independent accountant to adjudicate the amount owed under the closing statement. On April 12, 2023, the independent accountant issued its final and binding determination with respect to the disputed items and an additional $23.9 million was deemed in favor of TotalEnergies Renewables. We recorded a payable of $30.9 million in our condensed consolidated balance sheets as of April 2, 2023, and such amount was paid on April 19, 2023. Affiliation Agreement In April 2011, we and Total entered into an Affiliation Agreement that governs the relationship between Total and us (the “Affiliation Agreement”). Until the expiration of a standstill period specified in the Affiliation Agreement (the “Standstill Period”), and subject to certain exceptions, Total, TotalEnergies SE, and any of their respective affiliates and certain other related parties (collectively, the “Total Group”) may not effect, seek, or enter into discussions with any third party regarding any transaction that would result in the Total Group beneficially owning our shares in excess of certain thresholds, or request us or our independent directors, officers, or employees to amend or waive any of the standstill restrictions applicable to the Total Group. The Standstill Period ends when Total holds less than 15% ownership of us. The Affiliation Agreement imposes certain limitations on the Total Group’s ability to seek to effect a tender offer or merger to acquire 100% of our outstanding voting power and imposes certain limitations on the Total Group's ability to transfer 40% or more of our outstanding shares or voting power to a single person or group that is not a direct or indirect subsidiary of TotalEnergies SE. During the Standstill Period, no member of the Total Group may, among other things, solicit proxies or become a participant in an election contest relating to the election of directors to our Board. The Affiliation Agreement provides Total with the right to maintain its percentage ownership in connection with any new securities issued by us, and Total may also purchase shares on the open market or in private transactions with disinterested stockholders, subject in each case to certain restrictions. The Affiliation Agreement also imposes restrictions with respect to our and our Board’s ability to take certain actions, including specifying certain actions that require approval by the directors other than the directors appointed by Total and other actions that require stockholder approval by Total. On April 19, 2021, we entered into an amendment to the Affiliation Agreement with Total (the “April Affiliation Agreement Amendment”). The April Affiliation Agreement Amendment provided that our Board would include eleven members, composed of our president and chief executive officer, our immediate past chief executive officer, Tom Werner, six directors designated by Total, and three non-Total-designated directors. If the ownership of our voting securities by Total, together with the controlled subsidiaries of TotalEner gies SE, declined below certain thresholds, the number of members of the Board that Total was entitled to designate would be reduced as set forth in the Affiliation Agreement. Pursuant to the April Affiliation Agreement Amendment, Mr. Werner resigned from his position as a member of the Board on November 1, 2021. On October 29, 2021, we entered into an additional amendment to the Affiliation Agreement (the “October Affiliation Agreement Amendment”), which provided that our Board would re main at eleven members until March 31, 2022 and allowed for the appointme nt of one additional independent director to fill the vacancy created by Mr. Werner’s resignation from the Board, which was filled as of December 31, 2021. The October Affiliation Agreement Amendment further provided that, after March 31, 2022, the Board would revert to nine members, at which time one independent director and one Total designee would resign from the Board. As previously disclosed, on March 31, 2022, one independent director and one Total designee resigned from the Board, and the Board reverted to nine members as of such date. In accordance with the Letter Agreement entered into by TotalEnergies Renewables, GIP Sol, and HoldCo on September 12, 2022, GIP had the right to appoint two designees to our Board. On September 23, 2022, two Total designees resigned from the Board, and on September 26, 2022, the Board appointed two GIP designees. 4.00% Debentures Due 2023 In December 2015, we issued $425.0 million in principal amount of our 4.00% debentures due 2023. An aggregate principal amount of $100.0 million of the 4.00% debentures due 2023 was acquired by Total. On January 17, 2023, we repaid the outstanding principal amount of $425.0 million of our 4.00% debentures due 2023, $100.0 million of which was held by TotalEnergies, as well as the remaining interest on the 4.00% debentures due 2023 of $8.5 million which was payable upon maturity.

The revenue is recognized in an amount that reflects the consideration for the corresponding performance obligations for the goods and services transferred. Contract Assets and Liabilities Contract assets represent accounts receivable unbilled for transactions where revenue has been recognized in advance of billing the customer. Revenue may be recognized in advance of billing the customer, resulting in an amount recorded to “contract assets” or “accounts receivable, net” depending on the expected timing of payment for such unbilled accounts receivable. Once we have an unconditional right to consideration, we typically bill our customer and reclassify the “contract assets” to “accounts receivable, net.” Contract liabilities consist of deferred revenue and customer advances, which represent consideration received from a customer prior to transferring control of goods or services to the customer under the terms of a sales contract. Total contract assets and contract liabilities balances as of the respective dates are as follows: As of (In thousands) July 2, 2023 January 1, 2023 Contract assets $ 49,666 $ 51,001 Contract liabilities 1 $ 234,326 $ 155,764 1 As of July 2, 2023 and January 1, 2023, we had indemnifications of $1.0 million retained in connection with our C&I Solutions sale, which are presented within “contract liabilities, net of current portion” on our condensed consolidated balance sheets. During the three and six months ended July 2, 2023, we recognized revenue of $82.1 million and $91.4 million that was included in contract liabilities as of April 2, 2023 and January 1, 2023, respectively. During the three and six months ended July 3, 2022, we recognized revenue of $40.0 million and $38.1 million that was included in contract liabilities as of April 3, 2022 and January 2, 2022. As of July 2, 2023, we have entered into contracts with customers for sales of solar systems and components for an aggregate transaction price of $755.4 million, the substantial majority of which we expect to recognize over the next 12 months.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	GOODWILL AND INTANGIBLE ASSETSGoodwill On October 4, 2021, we entered into a Securities Purchase Agreement to acquire all of the issued and outstanding membership interests of Blue Raven Solar Holdings, LLC (“Blue Raven”) and 35% of the issued and outstanding membership interests in Albatross Software, LLC, an affiliate of Blue Raven. Goodwill presented on our condensed consolidated financial statements represents goodwill resulting from the acquisition of Blue Raven. We test goodwill impairment at least annually during the last day of the third fiscal quarter, or when events or changes in circumstances indicate that goodwill might be impaired. The evaluation of impairment involves comparing the current fair value of our reporting unit to the book value (including goodwill). We have the option to perform a qualitative assessment of goodwill prior to completing a quantitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. After assessing the totality of events and circumstances, we concluded that as of October 2, 2022, the date our last qualitative test was performed, it was more likely than not that the fair value of our reporting unit with goodwill was greater than the book value and, therefore, that there is no goodwill impairment.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement (observable inputs are the preferred basis of valuation): • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Measurements are inputs that are observable for assets or liabilities, either directly or indirectly, other than quoted prices included within Level 1. • Level 3 — Prices or valuations that require management inputs that are both significant to the fair value measurement and unobservable. Assets and Liabilities Measured at Fair Value on a Recurring Basis We measure certain assets and liabilities at fair value on a recurring basis. There were no transfers between fair value measurement levels during any presented period. The following tables summarize our assets and liabilities measured at fair value on a recurring basis: July 2, 2023 (In thousands) Carrying Value Total Fair Value Level 3 Level 2 Level 1 Assets Cash and cash equivalents: Money market funds $ 45,000 $ 45,000 $ — $ — $ 45,000 Loan receivables held for sale, net 12,917 12,917 — 12,917 — Prepaid expenses and other current assets: Interest rate swaps 80 80 — 80 — Other long-term assets: Equity investments with FVO 26,023 26,023 26,023 — — Equity investments with readily determinable fair value — — — — — Interest rate swaps 2,507 2,507 — 2,507 — Total assets $ 86,527 $ 86,527 $ 26,023 $ 15,504 $ 45,000 January 1, 2023 (In thousands) Carrying Value Total Fair Value Level 3 Level 2 Level 1 Assets Cash and cash equivalents: Money market funds $ 297,474 $ 297,474 $ — $ — $ 297,474 Other long-term assets: Equity investments with FVO 18,346 18,346 18,346 — — Equity investments with readily determinable fair value 132,480 132,480 — — 132,480 Interest rate swaps 2,293 2,293 — 2,293 — Total assets $ 450,593 $ 450,593 $ 18,346 $ 2,293 $ 429,954 Money market funds During fiscal 2022, we entered into investments in money market funds with Bank of America. As of July 2, 2023, we recorded an amount of $45.0 million within “cash and cash equivalents” in our consolidated balance sheets for our investments held in the money market funds. The money market funds are classified within Level 1 in the fair value hierarchy as we value the funds using observable inputs that reflect quoted prices for securities with identical characteristics. Loan receivables held for sale, net Loan receivables held for sale are recorded in the condensed consolidated balance sheets at amortized cost, and subsequently measured at the lower of cost or fair value on a recurring basis at each reporting period. Fair value of our loan receivables held for sale is determined based on the anticipated sale price of the solar loan receivables to third-parties. The loan receivables held for sale are classified within Level 2 of the fair value hierarchy, as the primary component of the price is obtained from observable values of loan receivables with similar terms and characteristics. Equity investments with fair value option (“FVO”) We have elected the FVO in accordance with the guidance in ASC 825, Financial Instruments , for our investment in the SunStrong Capital Holdings, LLC (“SunStrong”), Dorado Development Partners, LLC (“Dorado DevCo”), and SunStrong Partners, LLC (“SunStrong Partners”) joint ventures, to mitigate volatility in reported earnings that results from the use of different measurement attributes (see Note 9. Equity Investments ). We initially computed the fair value for our investments consistent with the methodology and assumptions that market participants would use in their estimates of fair value with the assistance of a third-party valuation specialist. The fair value computation is updated using the same methodology on an annual basis, during the third fiscal quarter, considering material changes in the business of SunStrong, Dorado DevCo, and SunStrong Partners or other inputs. The investments are classified within Level 3 in the fair value hierarchy because we estimate the fair value of the investments using the income approach based on the discounted cash flow method which considered estimated future financial performance, including assumptions for, among others, forecasted contractual lease income, lease expenses, residual value of these lease assets, and long-term discount rates, and forecasted default rates over the lease and loan term and discount rates, some of which require significant judgment by management and are not based on observable inputs. The following table summarizes movements in equity investments for the six months ended July 2, 2023. There were no internal movements between Level 1 or Level 2 fair value measurements to or from Level 3 fair value measurements for the six months ended July 2, 2023.

Included in the table are the inputs and range of possible inputs that have an effect on the overall valuation of the financial instruments. 2023 Assets: Fair value Valuation Technique Unobservable input Range (Weighted Average) Other long-term assets: Equity investments with FVO $ 26,023 Discounted cash flows Discount rate 12.5%-13% 1 7.5% 1 Total assets $ 26,023 1 The primary unobservable inputs used in the fair value measurement of our equity investments, when using a discounted cash flow model, are the discount rate and residual value. Significant increases (decreases) in the discount rate in isolation would result in a significantly lower (higher) fair value measurement. We estimate the discount rate based on risk appropriate projected cost of equity. We estimate the residual value based on the contracted systems in place in the years being projected. Significant increases (decreases) in the residual value in isolation would result in a significantly higher (lower) fair value measurement. Equity investments with readily determinable fair value In connection with the divestment of our microinverter business to Enphase on August 9, 2018, we received 7.5 million shares of Enphase common stock (NASDAQ: ENPH). The common stock received was recorded as an equity investment with readily determinable fair value (Level 1), with changes in fair value recognized in net income in accordance with ASU 2016-01 Recognition and Measurement of Financial Assets and Liabilities. On January 5, 2023, we sold our remaining 0.5 million shares of Enphase common stock in open market transactions for cash proceeds of $121.7 million, with a loss of $10.8 million, which was recorded within “other, net” in our condensed consolidated statement of operations for the six months ended July 2, 2023. During the six months ended July 3, 2022, we sold one million shares of Enphase common stock in open market transactions for net cash proceeds of $149.8 million, and recorded a gain of $1.3 million. Interest Rate Swaps Credit Suisse Interest Rate Swap In connection with the entry into our loan and security purchase agreement with Credit Suisse AG, New York Branch, and other financial institutions to finance our retail installment contract receivables on June 30, 2022, we also entered into interest rate swaps under the agreement, which convert the floating rate loan to a fixed rate. The interest rate swaps were entered into to mitigate the risks associated with interest rate volatility. The swaps terminate in September of 2026, unless we terminate with the maturity of the loan, subject to any early termination costs. The interest rate swaps qualify as derivatives in accordance with the guidance in ASC 815, Derivatives and Hedging . The fair value of the interest rate swaps is determined using a discounted cash flow model that incorporates an assessment of the risk of non-performance by the interest rate swap counterparty and an evaluation of credit risk in valuing derivative instruments. The valuation model uses various inputs including contractual terms, interest rate curves, credit spreads and measures of volatility. As of July 2, 2023, we recorded derivative assets of $2.5 million, within “ other long-term assets interest expense Bank of America Interest Rate Swap In the first quarter of fiscal 2023, we entered into interest rate swaps in our SunPower Financial TM business with Bank of America, which converts the fixed rate loans entered into by SunPower Financial's customers to floating rates. The interest rate swaps were entered into to mitigate the interest rate volatility risks associated with the timing lag between when the customer enters into these fixed rate loans and when the loan is funded and sold to a third-party investor. The swaps terminate beginning in September of 2023 through February of 2024. The interest rate swaps qualify as derivatives in accordance with the guidance in ASC 815, Derivatives and Hedging . The fair value of the interest rate swaps is determined using a discounted cash flow model that incorporates an assessment of the risk of non-performance by the interest rate swap counterparty and an evaluation of credit risk in valuing derivative instruments. The valuation model uses various inputs including contractual terms, interest rate curves, credit spreads and measures of volatility. As of July 2, 2023, we recorded derivative assets of $0.1 million, within “ prepaid expenses and other current assets total revenues Retail installment contract receivables, net The aggregate carrying value of our long-term retail installment contracts as of July 2, 2023 was $104.1 million, included within “accounts receivable, net” and “other long-term assets” on our condensed consolidated balance sheets. We measure the retail installment contracts using the amortized cost method, where the significant financing component amount is deferred and recognized as revenue over the contract term. The fair value of these receivables as of July 2, 2023 was $77.5 million. The fair value was determined using a third-party investor determined formula that starts with initial investor pricing by product, adjusted to account for the fair value impact relating to any changes in market spreads based on Level 2 inputs for the relevant benchmark interest rate and credit spread, as reported by Bloomberg.

On April 5, 2023, we entered into a new Master Supply Agreement with Waaree Energies Ltd. (“Waaree”) for the purchase of various photovoltaic modules and components to be used in our residential systems. On May 25, 2023, we terminated the Master Supply Agreement with Waaree, including all outstanding purchase orders, and the parties are discussing the disposition of work-in-progress at the time of termination. Waaree products continue to be warranted by Waaree in accordance with the relevant provisions of the Master Supply Agreement. We review the terms of all our long-term supply agreements annually and assess the need for any accruals for estimated losses on adverse purchase commitments, such as lower of cost or net realizable value adjustments that will not be recovered by future sales prices, forfeiture of advanced deposits and liquidated damages, as necessary. Product Warranties The following table summarizes accrued warranty activities for the three and six months ended July 2, 2023 and July 3, 2022: Three Months Ended Six Months Ended (In thousands) July 2, 2023 July 3, 2022 July 2, 2023 July 3, 2022 Balance at the beginning of the period $ 84,333 $ 78,496 $ 78,880 $ 80,282 Accruals for warranties issued during the period 10,233 3,610 20,561 3,866 Settlements and adjustments during the period (6,034) (3,522) (10,909) (5,564) Balance at the end of the period $ 88,532 $ 78,584 $ 88,532 $ 78,584 Pursuant to the Definitive Agreement entered into by us and TotalEnergies Renewables in connection with the sale of our C&I Solutions business, we agreed to indemnify TotalEnergies Renewables for certain projects that were sold as part of our business prior to the sale. During the three and six months ended July 2, 2023, we recorded an additional $1.9 million and $8.7 million of warranty expenses related to our indemnifications of TotalEnergies Renewables, respectively, which is included within “net (loss) income from discontinued operations attributable to stockholders” on our condensed consolidated statements of operations. Liabilities Associated with Uncertain Tax Positions Total liabilities associated with uncertain tax positions were $12.9 million and $12.3 million as of July 2, 2023 and January 1, 2023, respectively. These amounts are included within “other long-term liabilities” on our condensed consolidated balance sheets in their respective periods as they are not expected to be paid within the next 12 months. Due to the complexity and uncertainty associated with our tax positions, we cannot make a reasonably reliable estimate of the period in which cash settlement, if any, would be made for our liabilities associated with uncertain tax positions in other long-term liabilities. Indemnifications We are a party to various agreements under which we may be obligated to indemnify the counterparty with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale of assets, under which we customarily agree to hold the other party harmless against losses arising from a breach of warranties, representations and covenants related to such matters as title to assets sold, negligent acts, damage to property, validity of certain intellectual property rights, non-infringement of third-party rights, and certain tax-related matters including indemnification to customers under Section 48(c) of the Internal Revenue Code of 1986, as amended, regarding solar commercial investment tax credits (“ITCs”) and U.S. Treasury Department (“U.S. Treasury”) cash grant payments under Section 1603 of the American Recovery and Reinvestment Act (each a “Cash Grant”). Further, in connection with our sale of residential lease assets in fiscal 2018 to SunStrong, we provide Hannon Armstrong Sustainable Infrastructure Capital, Inc. (“Hannon Armstrong”) indemnification related to cash flow losses arising from a recapture of California property taxes on account of a change in ownership, recapture of federal tax attributes and cash flow losses from leases that do not generate the promised savings to homeowners. The maximum exposure to loss arising from the indemnification for SunStrong is limited to the consideration received for the solar power systems. In each of these circumstances, payment by us is typically subject to the other party making a claim to us that is contemplated by and valid under the indemnification provisions of the particular contract, which provisions are typically contract-specific, as well as bringing the claim under the procedures specified in the particular contract. These procedures typically allow us to challenge the other party’s claims or, in case of breach of intellectual property representations or covenants, to control the defense or settlement of any third-party claims brought against the other party. Further, our obligations under these agreements may be limited in terms of activity (typically to replace or correct the products or terminate the agreement with a refund to the other party), duration or amount. In some instances, we may have recourse against third parties or insurance covering certain payments made by us. In certain circumstances, we are contractually obligated to compensate customers and investors for losses they may suffer as a result of reductions in benefits received under ITCs and U.S. Treasury Cash Grant programs. The indemnity expires in conjunction with the statute of limitation and recapture periods in accordance with the underlying laws and regulations for such ITCs and related benefits. We apply for ITCs and Cash Grant incentives based on guidance provided by the Internal Revenue Service (“IRS”) and the U.S. Treasury, which include assumptions regarding the fair value of the qualified solar power systems, among others. Certain of our development agreements, sale-leaseback arrangements, and financing arrangements with tax equity investors incorporate assumptions regarding the future level of incentives to be received, which in some instances may be claimed directly by our customers and investors. Generally, such obligations would arise as a result of reductions to the value of the underlying solar power systems as assessed by the IRS. At each balance sheet date, we assess and recognize, when applicable, the potential exposure from these obligations based on all the information available at that time, including any audits undertaken by the IRS. The maximum potential future payments that we could have to make under this obligation would depend on the difference between the eligible basis claimed on the tax filing for the solar energy systems sold or transferred to indemnified parties and the values that the IRS may determine as the eligible basis for the systems for purposes of claiming ITCs or Cash Grants. We use the eligible basis for tax filing purposes determined with the assistance of independent third-party appraisals to determine the ITCs that are passed through to and claimed by the indemnified parties. We continue to retain certain indemnities, specifically, around ITCs, Cash Grants and California property taxes, even after the underlying portfolio of assets is sold to a third party. For contracts that have such indemnification provisions, we recognize a liability under ASC 460, Guarantees , for the estimated premium that would be required by a guarantor to issue the same guarantee in a standalone arm’s-length transaction with an unrelated party. We recognize such liabilities at the greater of the fair value of the indemnity or the contingent liability required to be recognized under ASC 450, Contingencies . We initially estimate the fair value of any such indemnities provided based on the cost of insurance policies that cover the underlying risks being indemnified and may purchase such policies to mitigate our exposure to potential indemnification payments. After an indemnification liability is recorded, we derecognize such amount typically upon expiration or settlement of the arrangement. As of July 2, 2023 and January 1, 2023, our provision was $8.2 million, primarily for tax-related indemnifications, of which $4.9 million was recorded within “contract liabilities, net of current portion,” “accrued liabilities,” and “other long-term liabilities” on our condensed consolidated balance sheets related to our indemnifications with TotalEnergies Renewables. SunPower is party to various supply agreements with Hemlock Semiconductor Operations, LLC (f/k/a Hemlock Semiconductor Corporation) and its affiliate, Hemlock Semiconductor, LLC, (collectively, the “Hemlock Agreements”), for the procurement of polysilicon. In connection with the Spin-off of Maxeon Solar, SunPower and Maxeon Solar entered into an agreement pursuant to which Maxeon Solar received the benefit of SunPower’s rights under the Hemlock Agreements (including SunPower’s deposits and advanced payments thereunder) and, in return, Maxeon Solar agreed to perform all of SunPower’s existing and future obligations under the Hemlock Agreements, including all take-or-pay obligations (the “Back-to-Back Agreement”). As of the first quarter of 2023, Maxeon Solar's commitment under the Hemlock Agreement was finalized. As of July 2, 2023, there are no further payment obligations remaining under the Hemlock Agreements or the Back-to-Back Agreement. Pursuant to the Separation and Distribution Agreement entered into by us and Maxeon Solar, we agreed to indemnify Maxeon Solar for any liabilities arising out of certain existing litigation relating to businesses contributed to Maxeon Solar in connection with the Spin-off. We expect to be actively involved in managing this litigation together with Maxeon Solar. The indemnity qualifies for the criteria for accounting under the guidance in ASC 460, and we have recorded the liability of litigation of $2.9 million as of July 2, 2023. In addition, as of July 2, 2023, we have retained a total of $29.8 million of warranty reserves related to our indemnification with TotalEnergies Renewables in connection with the sale of our C&I Solutions business, which is included within “accrued liabilities” and “other long-term liabilities” on our condensed consolidated balance sheets. Legal Matters We are party to various litigation matters and claims, including but not limited to intellectual property, environmental, and employment matters, that arise from time to time in the ordinary course of our business. While we believe that the ultimate outcome of such matters will not have a material adverse effect on us, their outcomes are not determinable and negative outcomes may adversely affect our financial position, liquidity, or results of operations.

As part of the program, dealers receive preferred access to SunPower solar, EV charging equipment, battery storage, and financial products offerings. In addition, we provide the dealers with enhanced lead generation and business strategy support. During fiscal 2022, we entered into four equity investments as part of the Dealer Accelerator Program. The equity investments made were in Sea Bright Solar, Inc for an equity interest of 20.0%, Freedom Solar Holdings, LLC, for an equity interest of 4.5%, EmPower CES, LLC for an equity interest of 20.0% and Renova Energy Corp. for an equity interest of 10.6%. In April 2023, as part of the Dealer Accelerator Program, we entered into an equity investment with LTL LED, LLC, d/b/a Wolf River Electric LLC (“Wolf River”). The investment included a cash payment for an equity interest of 16.7%. All of these equity investments were accounted for as equity method investments without readily determinable fair value in accordance with the guidance in ASC 323, Investments - Equity Method and Joint Ventures , given the material intra-entity transactions that exist under our exclusive supplier agreements as a result of our investments. We recognize our earnings from our equity method investments in the fiscal quarter after the corresponding earnings are recognized by the investee, and recorded earnings from equity method investments of $0.3 million and $0.6 million during the three and six months ended July 2, 2023, as compared to no earnings or losses from equity method investments during the three and six months ended July 3, 2022. In addition, during the three and six months ended July 2, 2023, we received a dividend from one of our investees in the amount of $0.2 million and $0.7 million. Variable Interest Entities (“VIEs”) A VIE is an entity that has either (i) insufficient equity to permit the entity to finance its activities without additional subordinated financial support, or (ii) equity investors who lack the characteristics of a controlling financial interest. We follow guidance on the consolidation of VIEs that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct activities that most significantly impact the investees' economic performance, including powers granted to the investees' governing board and, to a certain extent, a company's economic interest in the investee. We analyze our investments in VIEs and classify them as either unconsolidated VIEs or consolidated VIEs (refer to our Form 10-K for the fiscal year ended January 1, 2023 for further details on our various VIE arrangements). Unconsolidated VIEs In March 2022, we entered into a joint venture with Hannon Armstrong and SunStrong to form Dorado DevCo, a jointly-owned entity, to hold our residential lease solar power projects. Similar to our prior joint ventures for residential lease assets, SunPower and Hannon Armstrong will make total capital contributions of up to $15.1 million into Dorado DevCo for 50% effective equity interest, each. SunStrong, our existing joint venture with Hannon Armstrong, was appointed as a manager of the entity. We also entered into a development asset purchase agreement to provide development services for solar power systems sold into the fund. With respect to our interest in Dorado DevCo, we determined there is not sufficient equity at risk in the joint venture, thus, we determined the joint venture is a VIE as considered under the guidance in ASC 810 . Based on the assessment of the required criteria for consolidation, we determined that SunStrong, as the manager of Dorado DevCo, has the power to make decisions over activities that significantly affect Dorado DevCo and subsidiaries. We and Hannon Armstrong do not have the power to unilaterally make decisions that affect the performance of the investee, and we do not have kick-out rights to unilaterally buyout the other party's equity interests, while Hannon Armstrong has a right to purchase our equity interest of the investee. In addition, much of our exposure to absorb the losses of the VIE that could potentially be significant to the VIE, or the right to receive the economic interest from the VIE, is in our capacity as a developer and service provider, where we provide development services at market terms. Therefore, we concluded we are not the primary beneficiary of the investee, and we do not consolidate. During the three and six months ended July 2, 2023, we made $5.7 million and $7.1 million of capital contributions in the equity method investee, respectively. The investment contributed to our equity investment balance in SunStrong and is classified in “other long-term assets” on our condensed consolidated balance sheets. In April 2023, to support the expansion of our solar loan funding capacity, we entered into a series of agreements to sell solar loans to a special-purpose entity within our existing joint venture, SunStrong. The new special-purpose entity is an indirect wholly owned subsidiary of SunStrong. SunPower and Hannon Armstrong will make total capital contributions of up to $24.2 million into SunStrong for 51% and 49% effective equity interest, respectively. In these agreements, we serve as the primary or master servicer of the special-purpose entity, however, as the servicer, we do not have the power to make significant decisions impacting the performance of the entity. With respect to our interest in the special-purpose entity, we determined there is not sufficient equity at risk in the entity, thus, we determined the entity is a VIE as considered under the guidance in ASC 810. Based on the assessment of the required criteria for consolidation, we determined that SunStrong, as the manager of the special-purpose entity, has the power to make decisions over activities that significantly affect the entity and subsidiaries. Therefore, we concluded we are not the primary beneficiary of the entity, and we do not consolidate. During the three and six months ended July 2, 2023, we made a $0.6 million capital contribution in the equity method investee. The investment contributed to our equity investment balance in Dorado DevCo and is classified in “other long-term assets” on our condensed consolidated balance sheets. We have elected the FVO in accordance with the guidance in ASC 825, Financial Instruments , for our investments in SunStrong, SunStrong Partners, and Dorado DevCo, our unconsolidated VIEs.

As of July 2, 2023, the aggregate future contractual maturities of our outstanding debt, at face value, were as follows: (In thousands) Fiscal 2023 (remaining six months) Fiscal 2024 Fiscal 2025 Fiscal 2026 Fiscal 2027 Thereafter Total Aggregate future maturities of outstanding debt $ 10,706 $ 5,069 $ 5,073 $ 72,493 $ 260,080 $ 21 $ 353,442 October 2021 Letter of Credit Facility with Bank of the West In October 2021, we entered into a letter of credit facility with Bank of the West which provides for the issuance, upon our request, of letters of credit to support our obligations in an aggregate amount not to exceed $25.0 million. The letter of credit issued under the facility is 50% cash secured, and we have entered into a security agreement with Bank of the West granting them a security interest in a cash collateral account established for this purpose. As of July 2, 2023, letters of credit issued and outstanding under the Bank of the West facility totaled $24.3 million, which were collateralized with $12.5 million of restricted cash on the condensed consolidated balance sheets. Loan Facility with Credit Suisse AG On June 30, 2022, we entered into a loan and security purchase agreement with Credit Suisse AG, New York Branch, and other financial institutions, to finance our retail installment contract receivables. The agreement provided for a $100.0 million delayed draw term loan which will mature on December 29, 2023. In connection with the loan agreement, we have established a special purpose entity acting as the borrower under the facility. During the second quarter of fiscal 2023, we amended our loan agreement and extended the facility through June 29, 2026. The loans under the agreement bear interest at a rate as adjusted by the benchmark adjustment, as defined in the term loan agreement, or the base rate plus the applicable margin for such loans. In addition, we also entered into an interest rate swap under the agreement, which converts the floating rate loan to a fixed rate. The swap terminates in September of 2026, unless we terminate early with the maturity of the loan, subject to any early termination costs. The term loan agreement contains customary representations and warranties as well as customary affirmative and negative covenants, including a covenant that any assets of the special purpose borrowing entity will not be available to other creditors of any of our other SunPower entities. As of July 2, 2023, we had $67.4 million borrowings outstanding under the term loan facility, of which $0.7 million is being held in a Liquidity Reserve Account, in accordance with the loan and security purchase agreement, and is collateralized with restricted cash on the condensed consolidated balance sheets as of July 2, 2023. All borrowings outstanding under the term loan facility have a weighted average interest rate of between 6.2% to 7.2%. Revolver and Term Loan Facility with Bank of America and Bank of the West On September 12, 2022, we entered into a Credit Agreement with BofA Securities, Inc. and Bank of the West, as joint lead arrangers and joint bookrunners, and Bank of America, N.A., as Administrative Agent, Collateral Agent, Swingline Lender, and an L/C Issuer. The Credit Agreement consists of a revolving credit facility (the “Revolver”) and a term loan facility (“Term Loan Facility” and, together with the Revolver, the “Facilities”), each facility providing for an aggregate principal amount of $100 million. The Credit Agreement was amended on January 26, 2023, and provided for, among other things, an increase of the Revolver commitments by $100.0 million (the “Increased Revolving Commitments”), including CitiBank, N.A. and JP Morgan Chase Bank, N.A. as the 2023 Incremental Revolving Lenders’. The Increased Revolving Commitments are governed by the same terms and conditions applicable to the Revolver commitments under the Credit Agreement prior to the effectiveness of the Amendment. The Revolver and Term Loan Facility both mature on September 12, 2027. The interest rate for borrowings under the Facilities is based on, at the Company's option, either (1) the highest of (a) the Federal Funds Rate plus 0.50%, and (b) Bank of America's “prime rate” and (c) SOFR plus a margin, or (2) SOFR plus a margin. A commitment fee of between 0.25% and 0.35%, depending on our Total Net Leverage Ratio, is payable quarterly on the undrawn portion of the Revolver. The Credit Agreement contains affirmative and negative covenants customarily applicable to senior secured credit facilities, including covenants restricting the ability of the Company and certain of our subsidiaries, subject to negotiated exceptions, to: incur additional indebtedness; create liens or guarantee obligations; enter into sale-leaseback transactions; merge, liquidate or dispose of assets; make acquisitions or other investments; enter into hedging agreements; pay dividends and make other distributions and engage in transactions with affiliates. Under the Credit Agreement, the Company's Restricted Subsidiaries may not invest cash or property in, or loan to, our Unrestricted Subsidiaries amounts exceeding the limitations set forth in the Credit Agreement. As of July 2, 2023, we had borrowings of $97.5 million and $180.0 million under the Term Loan Facility and Revolver, respectively. The interest rate for the borrowings is SOFR plus a margin. In addition, as of July 2, 2023, we had no issued but undrawn letters of credit outstanding under the Facilities. The letters of credit have a maximum aggregate amount that can be issued of $50.0 million, which is included within the total principal amount of the Revolver facility.

Related-Party Transactions

Related Party Transactions [Abstract]
Related-Party Transactions	TRANSACTIONS WITH TOTAL AND TOTALENERGIES SE In June 2011, Total completed a cash tender offer to acquire 60% of our then outstanding shares of common stock at a price of $23.25 per share, for a total cost of approximately $1.4 billion. In December 2011, we entered into a Private Placement Agreement with Total, under which Total purchased, and we issued and sold, 18.6 million shares of our common stock for a purchase price of $8.80 per share, thereby increasing Total's ownership to approximately 66% of our outstanding common stock as of that date. On May 24, 2022, Total and Total Gaz (collectively, “Sellers”) agreed to sell 50% less one unit of the equity interests in HoldCo, which upon closing of such transaction would be the record holder of all of the shares of our common stock held by Sellers, to GIP Sol (and such transaction, the “Transaction”). On September 12, 2022, Sellers closed the Transaction. In connection with the completion of the Transaction, TotalEnergies Renewables, GIP Sol, and HoldCo entered into a Letter Agreement, dated September 12, 2022, concerning certain governance rights with respect to HoldCo and the shares of our common stock held directly by HoldCo. Specifically, TotalEnergies Renewables and GIP Sol agreed to, among other things, take all actions necessary to cause HoldCo to designate and elect to our board of directors (the “Board”) such individuals as HoldCo is entitled to appoint pursuant to the Affiliation Agreement; provided, however, that for so long as HoldCo is entitled to appoint at least five directors to our Board, GIP Sol shall have the right to appoint two of such five directors. The Letter Agreement also contained certain provisions on voting and on the transfer of HoldCo interests and common stock of the Company. As of July 2, 2023, ownership of our outstanding common stock by TotalEnergies SE and its affiliates, and GIP Sol, was 50.2%. Sale of C&I Solutions Business On May 31, 2022, pursuant to the terms of the Definitive Agreement we signed with TotalEnergies Renewables on February 6, 2022, TotalEnergies Renewables acquired all of the issued and outstanding common stock of our C&I Solutions business. The preliminary purchase price of $190.0 million was subject to certain adjustments, including cash, indebtedness, and an estimated closing date working capital adjustment. Upon closing, we received net cash consideration of $149.2 million based on the estimated net assets of the business on that date. As of the third quarter of fiscal 2022, we recorded a payable of $7.0 million to Total, based on our review of the closing date working capital and our submission of the closing statement. On October 25, 2022, we received a notice of disagreement from TotalEnergies Renewables with respect to the closing statement. As set forth in the Definitive Agreement, we appointed an independent accountant to adjudicate the amount owed under the closing statement. On April 12, 2023, the independent accountant issued its final and binding determination with respect to the disputed items and an additional $23.9 million was deemed in favor of TotalEnergies Renewables. We recorded a payable of $30.9 million in our condensed consolidated balance sheets as of April 2, 2023, and such amount was paid on April 19, 2023. Affiliation Agreement In April 2011, we and Total entered into an Affiliation Agreement that governs the relationship between Total and us (the “Affiliation Agreement”). Until the expiration of a standstill period specified in the Affiliation Agreement (the “Standstill Period”), and subject to certain exceptions, Total, TotalEnergies SE, and any of their respective affiliates and certain other related parties (collectively, the “Total Group”) may not effect, seek, or enter into discussions with any third party regarding any transaction that would result in the Total Group beneficially owning our shares in excess of certain thresholds, or request us or our independent directors, officers, or employees to amend or waive any of the standstill restrictions applicable to the Total Group. The Standstill Period ends when Total holds less than 15% ownership of us. The Affiliation Agreement imposes certain limitations on the Total Group’s ability to seek to effect a tender offer or merger to acquire 100% of our outstanding voting power and imposes certain limitations on the Total Group's ability to transfer 40% or more of our outstanding shares or voting power to a single person or group that is not a direct or indirect subsidiary of TotalEnergies SE. During the Standstill Period, no member of the Total Group may, among other things, solicit proxies or become a participant in an election contest relating to the election of directors to our Board. The Affiliation Agreement provides Total with the right to maintain its percentage ownership in connection with any new securities issued by us, and Total may also purchase shares on the open market or in private transactions with disinterested stockholders, subject in each case to certain restrictions. The Affiliation Agreement also imposes restrictions with respect to our and our Board’s ability to take certain actions, including specifying certain actions that require approval by the directors other than the directors appointed by Total and other actions that require stockholder approval by Total. On April 19, 2021, we entered into an amendment to the Affiliation Agreement with Total (the “April Affiliation Agreement Amendment”). The April Affiliation Agreement Amendment provided that our Board would include eleven members, composed of our president and chief executive officer, our immediate past chief executive officer, Tom Werner, six directors designated by Total, and three non-Total-designated directors. If the ownership of our voting securities by Total, together with the controlled subsidiaries of TotalEner gies SE, declined below certain thresholds, the number of members of the Board that Total was entitled to designate would be reduced as set forth in the Affiliation Agreement. Pursuant to the April Affiliation Agreement Amendment, Mr. Werner resigned from his position as a member of the Board on November 1, 2021. On October 29, 2021, we entered into an additional amendment to the Affiliation Agreement (the “October Affiliation Agreement Amendment”), which provided that our Board would re main at eleven members until March 31, 2022 and allowed for the appointme nt of one additional independent director to fill the vacancy created by Mr. Werner’s resignation from the Board, which was filled as of December 31, 2021. The October Affiliation Agreement Amendment further provided that, after March 31, 2022, the Board would revert to nine members, at which time one independent director and one Total designee would resign from the Board. As previously disclosed, on March 31, 2022, one independent director and one Total designee resigned from the Board, and the Board reverted to nine members as of such date. In accordance with the Letter Agreement entered into by TotalEnergies Renewables, GIP Sol, and HoldCo on September 12, 2022, GIP had the right to appoint two designees to our Board. On September 23, 2022, two Total designees resigned from the Board, and on September 26, 2022, the Board appointed two GIP designees. 4.00% Debentures Due 2023 In December 2015, we issued $425.0 million in principal amount of our 4.00% debentures due 2023. An aggregate principal amount of $100.0 million of the 4.00% debentures due 2023 was acquired by Total. On January 17, 2023, we repaid the outstanding principal amount of $425.0 million of our 4.00% debentures due 2023, $100.0 million of which was held by TotalEnergies, as well as the remaining interest on the 4.00% debentures due 2023 of $8.5 million which was payable upon maturity.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES In the three months ended July 2, 2023, our income tax provision of $0.2 million on a loss from continuing operations before income taxes and equity in earnings of unconsolidated investees of $30.3 million, was primarily due to the accrual of interest and penalties on prior year uncertain tax positions. Our income tax provision of $3.2 million in the three months ended July 3, 2022 on a loss from continuing operations before income taxes of $38.5 million was primarily due to changes in the forecasted annual effective tax rate, partially offset by a decrease in the deferred tax liability due to mark-to-market unrealized losses on equity investments. In the six months ended July 2, 2023, our income tax provision of $1.5 million o n a loss from co ntinuing operations before income taxes and equity in earnings of unconsolidated investees of $72.6 million, was primarily due to discrete items including taxes on realized gains from sale of equity investments and accrual of interest and penalties on prior year uncertain tax positions. Our income tax benefit of $8.4 million in the six months ended July 3, 2022 on a loss from continuing operations before income taxes of $52.6 million was primarily due to the reversal of deferred taxes previously accrued for California as a result of the enactment of Senate Bill 113 which restored the ability to utilize net operating losses in 2022. During the three and six months ended July 2, 2023, in accordance with FASB guidance for interim reporting of income tax, our annual effective tax rate was computed based on year to date results. The income tax differs from the amounts computed by applying the statutory income tax rate to the loss from continuing operations before income tax primarily as a result of our valuation allowance and discrete items recorded during the quarter. Our income tax benefit on the loss from discontinued operations before income taxes of $2.8 million and $10.2 million, for the three and six months ended July 2, 2023, respectively, was insignificant. In the three and six months ended July 3, 2022 , our income tax benefit of $0.2 million and $0.6 million on a loss from discontinued operations before income taxes of $20.9 million and $47.2 million, respectively, was primarily due to the state tax benefit of year-to-date operating losses of the C&I Solutions business. Total liabilities associated with u ncertain tax positions were $12.9 million and $12.3 million as of July 2, 2023 and January 1, 2023, respectively. The increase of $0.6 million was primarily due to the accrual of additional state liabilities, and interest and penalties on existing reserves.

Net (Loss) Income Per Share

Net (Loss) Income Per Share	6 Months Ended

Earnings Per Share [Abstract]
Net (Loss) Income Per Share	NET (LOSS) INCOME PER SHARE We calculate basic net (loss) income per share by dividing earnings allocated to common stockholders by the basic weighted-average number of common shares outstanding for the period. Diluted weighted-average shares is computed by using the basic weighted-average number of common shares outstanding plus any potentially dilutive securities outstanding during the period using the if-converted method, except when their effect is anti-dilutive. Potentially dilutive securities include restricted stock units and the outstanding senior convertible debentures. The guidance in ASC 260, Earnings Per Share, requires that companies use income from continuing operations as a “ control number ” or benchmark to determine whether potential common shares are dilutive or antidilutive. When calculating discontinued operations, we used the same number of potential common shares used in computing the diluted per-share amount of income from continuing operations in computing all other reported diluted per-share amounts, even if the effect will be antidilutive compared to their respective basic per-share amounts.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTSOn July 24, 2023, we adopted a restructuring plan to align operating costs with current market conditions driven by slower sales partly due to higher interest rates. The plan is intended to improve near-term financial strength in order to remain competitive for future market conditions. As part of the restructuring plan, we expect approximately 140 employees, representing approximately 5% of our labor costs, to exit the Company in the third quarter of fiscal 2023. We expect to incur restructuring charges totaling approximately $4.3 million, consisting primarily of severance benefits. A substantial portion of such charges are expected to be incurred in the third quarter of fiscal 2023. The actual timing and costs of the plan may differ from our current expectations and estimates.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared by us in accordance with generally accepted accounting principles in the United States (“United States” or “U.S.,” and such accounting principles, “U.S. GAAP”) for interim financial information, and include the accounts of SunPower, all of our subsidiaries and special purpose entities, as appropriate under U.S. GAAP. All intercompany transactions and balances have been eliminated in consolidation. The financial information included herein is unaudited, and reflects all adjustments which are, in the opinion of our management, of a normal recurring nature and necessary for a fair statement of the results for the periods presented. The January 1, 2023 consolidated balance sheet data was derived from SunPower’s audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended January 1, 2023, as filed with the Securities and Exchange Commission (“SEC”) on March 10, 2023, but does not include all disclosures required by U.S. GAAP. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in SunPower's Annual Report on Form 10-K for the fiscal year ended January 1, 2023. The operating results for the three and six months ended July 2, 2023 are not necessarily indicative of the results that may be expected for fiscal year 2023, or for any other future period.
Fiscal Periods	We have a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. Accordingly, every fifth or sixth year will be a 53-week fiscal year. Both the current fiscal year, fiscal 2023, and prior fiscal year, fiscal 2022, are 52-week fiscal years. The second quarter of fiscal 2023 ended on July 2, 2023, while the second quarter of fiscal 2022 ended on July 3, 2022.
Management Estimates	Management Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosures of contingent assets and liabilities reported in these condensed consolidated financial statements and accompanying notes. We base our estimates on historical experience and various other assumptions believed to be reasonable. Our actual financial results could materially differ from those estimates. Significant estimates in these condensed consolidated financial statements include revenue recognition, specifically nature and timing of satisfaction of performance obligations, standalone selling price of performance obligations, and variable consideration; credit losses, including estimating macroeconomic factors affecting historical recovery rate of receivables; inventory write-downs; long-lived assets and goodwill impairment, specifically estimates for valuation assumptions including discount rates and future cash flows; fair value of investments, including equity investments for which we apply the fair value option and other financial instruments; actuarial estimates related to our self-insured health benefits; valuation of goodwill and intangible assets acquired in a business combination; valuation of contingent consideration in a business combination; valuation of contingencies such as warranty and litigation; the incremental borrowing rate used in discounting of lease liabilities; the fair value of indemnities provided to customers and other parties; and income taxes and tax valuation allowances.
Segment Information	Segment Information We operate in a single operating segment, providing solar power systems and services to residential customers. While our chief executive officer, as the chief operating decision maker (“CODM”), reviews financial information by different functions and revenue streams, he considers the business on a consolidated basis for purposes of allocating resources and reviewing overall business performance.
Revenue Recognition	Revenue Recognition We recognize revenue from contracts with customers when we have completed our performance obligations under an identified contract. The revenue is recognized in an amount that reflects the consideration for the corresponding performance obligations for the goods and services transferred. Solar Power Systems and Component Sales A majority of our revenue is generated by sales of fully functioning solar power systems to our customers. We sell our products through a network of installing and non-installing dealers and resellers, as well as our internal sales team. Usually, our performance obligation is to design and install a fully functioning solar energy system. We recognize revenue when the solar power system is fully installed and the final permit is received from the authority having jurisdiction, as we deem our performance obligation under the contract to be complete at such time, and the customer retains all of the significant risks and rewards of ownership of the solar power system. In situations when we are not responsible for construction and installation of solar power systems, usually when the sales are made by one of our installing dealers or resellers, we recognize revenue when the components of the solar power system are delivered at the customer site. All costs to obtain and fulfill contracts associated with system sales are expensed as a cost of revenue when we have fulfilled our performance obligations. Revenue is generally recognized at transaction price, net of costs of financing, or other consideration paid to the customers that is not in exchange for a distinct good or service. Also, our arrangements may contain clauses that can either increase or decrease the transaction price. Variable consideration is estimated at each measurement date at its most likely amount to the extent that it is probable that a significant reversal of cumulative revenue recognized will not occur and true-ups are applied prospectively as such estimates change. We also provide solar power systems to our customers in the form of 20-year lease agreements which are entered into by the customer with our third-party leasing partners. These third-party leasing partners are special-purpose entities that we do not control or consolidate. We recognize revenue when the system is fully installed, when permit to operate is given by the local utility company, and the solar system has produced meterable quantities of electricity, as we deem our performance obligation under the contract to be complete at such time.
Transfer of financial assets	Transfers of financial assets In April 2023, to support the expansion of our residential solar and storage loan funding capacity, we entered into a series of agreements to sell solar loan receivables to a special-purpose entity in our existing joint venture, SunStrong, with Hannon Armstrong Sustainable Infrastructure Capital, Inc. (“HASI”). Under the agreements, we have secured financing commitments to fund more than $450.0 million for our residential solar and storage loan program, including a $300.0 million revolving credit facility from Credit Agricole Corporate & Investment Bank (“CA-CIB”). The CA-CIB credit revolver serves as a warehouse facility for SunStrong to temporarily finance solar assets prior to arranging long-term financings, such as asset-backed securities. The revolving warehouse facility will allow SunStrong to fund the acquisition of solar loans entered into by SunPower Financial's customers and issue asset-backed securities on an ongoing basis. In May 2023, to further support the expansion of our residential solar and storage loan funding capacity, we also entered into a series of agreements to sell solar loan receivables to a newly created special-purpose trust beneficially owned by one or more affiliates of KKR Credit Advisors (US) LLC (“KKR Credit”). Under the agreements, we have secured financing commitments to fund up to $550.0 million for our residential solar and storage loan program over a 15-month term, with annual renewal options. These agreements to sell solar loan receivables to third-parties are accounted for in accordance with ASC 860 , Transfers and Servicing . We make judgments, based in part, on supporting legal opinions, on whether these entities should be consolidated as a variable interest entity, as defined in ASC 810, Consolidation , and whether the transfers to these entities are accounted for as a sale of a financial asset or a secured borrowing under ASC 860 (see Note 9. Equity Investments for a discussion of our conclusion under ASC 810). Under ASC 860, for our loan receivables that are held for sale and the transfer of the financial assets to be considered a sale, the asset must be legally isolated from the transferor and the transferee must have actual and effective control of the asset. When the sale criteria are met, we, as the transferor, derecognize the lower of cost or fair value of the financial asset transferred and recognize a net gain or loss on the sale based on the excess of the proceeds received (less any transaction costs) over the carrying value or fair value. We do not retain actual or effective control in the transferred loan receivables, and therefore, the transfers are accounted for as a sale with the gain or loss from the sales included in our condensed consolidated statements of operations. The gain or loss, and cash proceeds, related to the sales of the financial assets are classified as operating activities in our condensed consolidated statements of cash flows. Our loan receivables are held for sale and recorded at carrying value when purchased, equal to the purchase price plus fees incurred. We subsequently measure our loan receivables held for sale at the lower of cost or fair value on an aggregate portfolio basis until the loan receivables are sold. Our loan receivables held for sale are typically sold within 30 days of origination. If the purchased loans do not meet the eligibility criteria to be sold, the loan receivables are transferred to held to maturity and included at amortized cost within “accounts receivable, net” and “other long-term assets” on our condensed consolidated balance sheets. These loan receivable agreements held to maturity have a term of typically 20 - 25 years and relate to loans that our customers enter into to pay for their solar power systems.
