Nature of Business, Liquidity and Basis of Presentation	Nature of Business, Liquidity and Basis of Presentation Nature of Business For information on the nature of our business, see Part II, Item 8, Note 1 - Nature of Business, Liquidity and Basis of Presentation, Nature of Business section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Liquidity We have generally incurred operating losses and negative cash flows from operations since our inception. With the series of new debt offerings, debt extinguishments, and conversions to equit y that we completed during 2022 and the first three quarters of 2023, we had $840.5 million of total outstanding recourse debt as of September 30, 2023, which was classified as long-term debt. On March 20, 2023, we entered into an Amendment (the “ Amended SPA”) to the Securities Purchase Agreement with SK ecoplant, dated October 23, 2021 (the “ SPA”), and the Investor Agreement, dated December 29, 2021 , pursuant to which we issued and sold to SK ecoplant 13,491,701 shares of Series B redeemable convertible preferred stock (the “Series B RCPS ” ) for cash proceeds of $311.0 million. For additional information, please see Part I, Item 1, Note 16 - SK ecoplant Strategic Investment . On March 20, 2023, in connection with the Amended SPA we also entered into a Shareholders’ Loan Agreement with SK ecoplant (the “Loan Agreement”), pursuant to which we were entitled to draw down on a loan from SK ecoplant with a maximum principal amount of $311.0 million, if SK ecoplant sent a redemption notice to us under the Amended SPA or otherwise reduced any portion of its holdings of our Class A common stock. On September 23, 2023, all 13,491,701 shares of the Series B RCPS were automatically converted into shares of our Class A common stock. For additional information, please see Part I, Item 1, Note 11 - Related Party Transactions and Note 16 - SK ecoplant Strategic Investment . On May 16, 2023, we issued 3% Green Convertible Senior Notes (the “3% Green Notes ” ) in an aggregate principal amount of $632.5 million due June 2028, unless earlier repurchased, redeemed or converted, less the initial purchasers’ discount of $15.8 million and other issuance costs of $4.0 million, resulting in net proceeds of $612.7 million. On June 1, 2023, we used approximately $60.9 million of the net proceeds from this offering to redeem all of the outstanding principal amount of our 10.25% Senior Secured Notes due March 2027. The redemption price equaled 104% of the principal amount redeemed plus accrued and unpaid interest. For additional information, please see Part I, Item 1, Note 7 - Outstanding Loans and Security Agreements . On August 24, 2023, as part of the repowering of PPA V Investment Company and Operating Company (“PPA V”), our Power Purchase Agreement (“PPA”) entity, we paid off the outstanding balance and related accrued interest of $118.5 million and $0.5 million, respectively, of our 3.04% Senior Secured Notes due June 30, 2031. For additional information, please see Part I, Item 1, Note 7 - Outstanding Loans and Security Agreements . Our future capital requirements depend on many factors, including our rate of revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, the rate of growth in the volume of system builds, and the need for additional manufacturing space, the expansion of sales and marketing activities both in domestic and international markets, market acceptance of our product, our ability to secure financing for customer use of our Energy Servers, the timing of installations, and overall economic conditions, including the inflationary pressure in the U.S. on our ongoing and future operations. The rising interest rate environment in the U.S. has and may continue to adversely impact the cost of new capital deployment. In the opinion of management, the combination of our existing cash and cash equivalents and the expected timing of operating cash flows is expected to be sufficient to meet our operational and capital cash flow requirements and other cash flow needs for the next 12 months from the date of issuance of this Quarterly Report on Form 10-Q. Inflation Reduction Act of 2022 – New and Expanded Production and Tax Credits for Manufacturers and Projects to Support Clean Energy For information on the Inflation Reduction Act of 2022 (the “IRA”) signed into law on August 16, 2022, and its impact on our business, see Part II, Item 8, Note 1 - Nature of Business, Liquidity and Basis of Presentation, Inflation Reduction Act of 2022 section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Basis of Presentation We have prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), including all disclosures required by generally accepted accounting principles as applied in the United States (“U.S. GAAP”). Principles of Consolidation For information on the principles of consolidation, see Part II, Item 8, Note 1 - Nature of Business, Liquidity and Basis of Presentation, Principles of Consolidation section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Business Combinations For information on the business combinations, see Part II, Item 8, Note 1 - Nature of Business, Liquidity and Basis of Presentation, Business Combinations section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Use of Estimates For information on the use of accounting estimates, see Part II, Item 8, Note 1 - Nature of Business, Liquidity and Basis of Presentation, Use of Estimates section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Concentration of Risk Geographic Risk - The majority of our revenue for the three and nine months ended September 30, 2023 was attributable to operations in the United States and, for the three and nine months ended September 30, 2022, to operations in the Republic of Korea. A major portion of our long-lived assets is attributable to operations in the United States for all periods presented. In addition to shipments in the U.S. and the Republic of Korea, we also ship our Energy Servers to other countries, primarily Japan and India (the markets of the Republic of Korea, Japan and India, collectively referred to as the “Asia Pacific region”). In the three and nine months ended September 30, 2023, total revenue related to shipments to the Asia Pacific region was 35% and 24%, respectively. In the three and nine months ended September 30, 2022, total revenue related to shipments to the Asia Pacific region was 58% and 61%, respectively. Credit Risk - At September 30, 2023, two customers accounted for approximately 72% and 18% of accounts receivable. At December 31, 2022, one customer represented approximately 75% of accounts receivable. To date, we have not experienced any credit losses. Customer Risk - During the three months ended September 30, 2023, revenue from two customers accounted for approximately 40% and 31% of our total revenue. During the nine months ended September 30, 2023, two customers represented approximately 36% and 24% of our total revenue. During the three months ended September 30, 2022, two customers represented approximately 54% and 26% of our total revenue. During the nine months ended September 30, 2022, two customers represented approximately 48% and 16% of our total revenue.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Contract Balances The following table provides information about accounts receivables, contract assets, customer deposits and deferred revenue from contracts with customers (in thousands): September 30, December 31, 2023 2022 Accounts receivable $ 334,495 $ 250,995 Contract assets 143,875 46,727 Customer deposits 66,043 121,085 Deferred revenue 67,613 94,355 Contract assets relate to contracts for which revenue is recognized upon transfer of control of performance obligations, but where billing milestones have not been reached. Customer deposits and deferred revenue include payments received from customers or invoiced amounts prior to transfer of controls of performance obligations. At December 31, 2022, customer deposits included $24.6 million related to transactions with SK ecoplant, and refundable fees received from customers. At September 30, 2023 there were no customer deposits related to transactions with SK ecoplant (see Note 16 - SK ecoplant Strategic Investment ). Contract assets and contract liabilities are reported in a net position on an individual contract basis at the end of each reporting period. Contract assets are classified as current in the condensed consolidated balance sheets when both the milestones other than the passage of time, are expected to be complete and the customer is invoiced within one year of the balance sheet date, and as long-term when both the above-mentioned milestones are expected to be complete, and the customer is invoiced more than one year out from the balance sheet date. Contract liabilities are classified as current in the condensed consolidated balance sheets when the revenue recognition associated with the related customer payments and invoicing is expected to occur within one year of the balance sheet date and as long-term when the revenue recognition associated with the related customer payments and invoicing is expected to occur in more than one year from the balance sheet date. Contract Assets Three Months Ended Nine Months Ended 2023 2022 2023 2022 Beginning balance $ 35,182 $ 33,374 $ 46,727 $ 25,201 Transferred to accounts receivable from contract assets recognized at the beginning of the period (8,284) (21,677) (31,968) (21,304) Revenue recognized and not billed as of the end of the period 116,977 14,071 129,116 21,871 Ending balance $ 143,875 $ 25,768 $ 143,875 $ 25,768 Contract assets as of September 30, 2023 were primarily related to the PPA V Upgrade. For additional information, please see Part I, Item 1, Note 10 - Portfolio Financings . Deferred Revenue Deferred revenue activity, including deferred incentive revenue activity, during the three and nine months ended September 30, 2023 and 2022 consisted of the following (in thousands): Three Months Ended Nine Months Ended 2023 2022 2023 2022 Beginning balance $ 85,110 $ 96,377 $ 94,355 $ 115,476 Additions 243,545 248,574 733,891 597,318 Revenue recognized (261,042) (241,795) (760,633) (609,638) Ending balance $ 67,613 $ 103,156 $ 67,613 $ 103,156 Deferred revenue is equivalent to the total transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, as of the end of the period. Primary component of deferred revenue at the end of the period consists of performance obligations relating to the provision of maintenance services under current contracts and future renewal periods. Some of these obligations provide customers with material rights over a period that we estimate to be largely commensurate with the period of their expected use of the associated Energy Server. As a result, we expect to recognize these amounts as revenue over a period of up to 21 years, predominantly on a relative standalone selling price basis that reflects the cost of providing these services. Deferred revenue also includes performance obligations relating to product acceptance and installation. A significant amount of this deferred revenue is reflected as additions and revenue recognized in the same 12-month period, and a portion of this deferred revenue is expected to be recognized beyond this 12-month period mainly due to deployment schedules. We do not disclose the value of the unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. Disaggregated Revenue We disaggregate revenue from contracts with customers into four revenue categories: product, installation, services and electricity (in thousands): Three Months Ended Nine Months Ended 2023 2022 2023 2022 Revenue from contracts with customers: Product revenue $ 304,976 $ 213,243 $ 713,427 $ 520,415 Installation revenue 21,916 22,682 66,762 48,964 Services revenue 47,535 37,347 130,496 111,012 Electricity revenue 9,012 2,875 16,816 8,352 Total revenue from contract with customers 383,439 276,147 927,501 688,743 Revenue from contracts that contain leases: Electricity revenue 16,829 16,127 49,053 47,806 Total revenue $ 400,268 $ 292,274 $ 976,554 $ 736,549

In August 2023, we sold the PPA V entity as a result of the PPA V Repowering of Energy Servers (see Note 10 - Portfolio Financings) , and as such there were no balances related to PPA V in the condensed consolidated balance sheet as of September 30, 2023. In addition, the restricted cash held in the PPA II and PPA IIIb entities as of September 30, 2023 included $28.1 million and $0.9 million of current restricted cash, respectively, and $12.3 million and $6.7 million of non-current restricted cash, respectively.

These entities are not considered VIEs. Factoring Arrangements We sell certain customer trade receivables on a non-recourse basis under factoring arrangements with certain financial institutions. These transactions are accounted for as sales and cash proceeds are included in cash used in operating activities. We derecognized $108.0 million and $167.6 million of accounts receivable during the three and nine months ended September 30, 2023, respectively. We derecognized $146.3 million and $283.3 million of accounts receivable during the three and nine months ended September 30, 2022, respectively. The costs of factoring such accounts receivable on our condensed consolidated statements of operations for the three and nine months ended September 30, 2023 were $2.0 million and $2.7 million, respectively. The costs of factoring for the three and nine months ended September 30, 2022 were $2.5 million and $3.7 million, respectively. The costs of factoring are recorded in general and administrative expenses.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis The tables below set forth, by level, our financial assets that are accounted for at fair value for the respective periods. The table does not include assets and liabilities that are measured at historical cost or any basis other than fair value (in thousands): Fair Value Measured at Reporting Date Using September 30, 2023 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 489,395 $ — $ — $ 489,395 $ 489,395 $ — $ — $ 489,395 Liabilities Derivatives: Embedded EPP derivatives $ — $ — $ 3,948 $ 3,948 $ — $ — $ 3,948 $ 3,948 Fair Value Measured at Reporting Date Using December 31, 2022 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 291,903 $ — $ — $ 291,903 $ 291,903 $ — $ — $ 291,903 Liabilities Derivatives: Embedded EPP derivatives $ — $ — $ 5,895 $ 5,895 $ — $ — $ 5,895 $ 5,895 Money Market Funds - Money market funds are valued using quoted market prices for identical securities and are therefore classified as Level 1 financial assets. Embedded Escalation Protection Plan Derivative Liability in Sales Contracts - We estimate the fair value of the embedded EPP derivatives in certain sales contracts using a Monte Carlo simulation model, which considers various potential electricity price curves over the sales contracts’ terms. We use historical grid prices and available forecasts of future electricity prices to estimate future electricity prices. We have classified these derivatives as a Level 3 financial liability. The changes in the Level 3 financial liabilities during the nine months ended September 30, 2023 were as follows (in thousands): Embedded EPP Derivative Liability Liabilities at December 31, 2022 $ 5,895 EPP liability settlement (3,160) Changes in fair value 1,213 Liabilities at September 30, 2023 $ 3,948 In June 2023, per an EPP agreement with one of our customers, we paid $3.2 million, which was recorded as a reduction to our balance of embedded EPP derivative liability as of September 30, 2023. Financial Assets and Liabilities and Other Items Not Measured at Fair Value on a Recurring Basis Debt Instruments - The senior secured notes and convertible notes are based on rates currently offered for instruments with similar maturities and terms (Level 2).

Non-recourse debt refers to debt that is recourse to only our subsidiaries. The differences between the unpaid principal balances and the net carrying values apply to deferred financing costs. We and all of our subsidiaries were in compliance with all financial covenants as of September 30, 2023 and December 31, 2022. Recourse Debt Facilities 3% Green Convertible Senior Notes due June 2028 - On May 16, 2023, we issued the 3% Green Notes in an aggregate principal amount of $632.5 million due on June 1, 2028, unless earlier repurchased, redeemed or converted, less an initial purchasers’ discount of $15.8 million and other issuance costs of $4.0 million (together, the “Transaction Costs”), resulting in net proceeds of $612.7 million. The 3% Green Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of May 16, 2023, between us and U.S. Bank Trust Company, National Association, as Trustee, in private placements to qualified institutional buyers pursuant to Rule 144A of the Securities Act of 1933, as amended (the “Securities Act”). Pursuant to the purchase agreement among the Company and the representatives of the initial purchasers of the 3% Green Notes, the Company granted the initial purchasers an option to purchase up to an additional $82.5 million aggregate principal amount of the 3% Green Notes (the “Greenshoe Option”). The 3% Green Notes issued on May 16, 2023, included $82.5 million aggregate principal amount pursuant to the full exercise by the initial purchasers of the Greenshoe Option. The 3% Green Notes are senior, unsecured obligations accruing interest at a rate of 3% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2023. We may not redeem the 3% Green Notes prior to June 5, 2026, subject to a partial redemption limitation. We may elect to redeem, at face value, all or any portion of the 3% Green Notes at any time, and from time to time, on or after June 5, 2026 and on or before the forty-sixth scheduled trading day immediately before the maturity date, provided the share price for our Class A common stock exceeds 130% of the conversion price at redemption. Before March 1, 2028, the noteholders have the right to convert their 3% Green Notes only upon the occurrence of certain events, including satisfaction of a condition relating to the closing price of our common stock (the “Closing Price Condition”) or the trading price of the 3% Green Notes (the “Trading Price Condition”), a redemption event, or other specified corporate events. If the Closing Price Condition is met on at least 20 (whether or not consecutive) of the last 30 consecutive trading days in any calendar quarter, and only during such calendar quarter, the noteholders may convert their 3% Green Notes at any time during the immediately following quarter, commencing after the calendar quarter ending on September 30, 2023, subject to partial redemption limitation. Subject to the Trading Price Condition, the noteholders may convert their 3% Green Notes during the five business days immediately after any five consecutive trading day period in which the trading price per $1,000 principal amount of the 3% Green Notes, as determined following a request by a holder of the 3% Green Notes, for each day of that period is less than 98% of the product of the closing price of our common stock and the then applicable conversion rate. From and after March 1, 2028, the noteholders may convert their 3% Green Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. Should the noteholders elect to convert their 3% Green Notes, we may elect to settle the conversion by paying or delivering, as applicable, cash, shares of our Class A common stock, $0.0001 par value per share, or a combination thereof, at our election. The initial conversion rate is 53.0427 shares of Class A common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $18.85 per share of Class A common stock. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. Also, we may increase the conversion rate at any time if our Board of Directors determines it is in the best interests of the Company or to avoid or diminish income tax to holders of common stock. In addition, if certain corporate events that constitute a Make-Whole Fundamental Change, as defined below, occur, then the conversion rate applicable to the conversion of the 3% Green Notes may, in certain circumstances, be increased by up to 22.5430 shares of Class A common stock per $1,000 principal amount of notes for a specified period of time. At September 30, 2023, the maximum number of shares into which the 3% Green Notes could have been potentially converted if the conversion features were triggered was 47,807,955 shares of Class A common stock. According to the Indenture, a Make-Whole Fundamental Change means (i) a Fundamental Change, that includes certain change-of-control events relating to us, certain business combination transactions involving us and certain delisting events with respect to our Class A common stock, or (ii) the sending of a redemption notice with respect to the 3% Green Notes. The 3% Green Notes contain certain customary provisions relating to the occurrence of Events of Default, as defined in the Indenture. If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to us occurs, then the principal amount of, and all accrued and unpaid interest on, all of the 3% Green Notes then outstanding will immediately become due and payable without any further action or notice by any person. However, notwithstanding the foregoing, we may elect, at our option, that the sole remedy for an Event of Default relating to certain failures by us to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the 3% Green Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the 3% Green Notes. The Transaction Costs were recorded as debt issuance costs and presented a reduction to the 3% Green Notes on our condensed consolidated balance sheets and are amortized to interest expense at an effective interest rate of 3.8%. Total interest expense recognized related to the 3% Green Notes for the three and nine months ended September 30, 2023 was $5.7 million and $8.7 million, respectively, and was comprised of contractual interest expense of $4.7 million and $7.2 million, respectively, and amortization of the initial purchasers’ discount and other issuance costs of $1.0 million and $1.5 million, respectively. We have not recognized any special interest expense related to the 3% Green Notes to date. The amount of unamortized debt issuance costs as of September 30, 2023, was $18.3 million. Although the 3% Green Notes contain embedded conversion features, we account for the 3% Green Notes in its entirety as a liability. As of September 30, 2023, the net carrying value of the 3% Green Notes was classified as a long-term liability in our condensed consolidated balance sheets. Capped Calls - On May 11, 2023, in connection with the pricing of the 3% Green Notes, and on May 15, 2023, in connection with initial purchasers’ exercise of the Greenshoe Option, we entered into privately negotiated capped call transactions (the “Capped Calls”) with certain counterparties (the “Option Counterparties”). The Capped Calls cover, subject to customary anti-dilution adjustments substantially similar to those applicable to the 3% Green Notes, the aggregate number of shares of our Class A common stock that initially underlie the 3% Green Notes, and are expected generally to reduce potential dilution to holders of our common stock upon any conversion of the 3% Green Notes and at our election (subject to certain conditions) offset any cash payments we would be required to make in excess of the principal amount of converted 3% Green Notes. The Capped Calls expire on June 1, 2028 and are exercisable only at maturity, but may be early terminated in various circumstances, including if the 3% Green Notes are early converted or repurchased. The default settlement method for the Capped Calls is net share settlement. However, we may elect to settle the Capped Calls in cash. The Capped Calls have an initial strike price of approximately $18.85 per share of Class A common stock, subject to certain adjustments. The strike price of $18.85 corresponds to the initial conversion price of the 3% Green Notes. The number of shares underlying the Capped Calls is 33,549,508 shares of Class A common stock. The cap price of the Capped Calls is initially $26.46 per share of Class A common stock, which represents a premium of 100% over the last reported sale price of our common stock on May 11, 2023. The Capped Calls are freestanding financial instruments. We used a portion of the proceeds from the issuance of the 3% Green Notes to pay for the Capped Calls’ premium. As the Capped Calls meet certain accounting criteria, they are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $54.5 million incurred to purchase the Capped Calls was recorded as a reduction to additional paid-in capital on our condensed consolidated balance sheets and will not be remeasured. Please refer to Part II, Item 8, Note 7 - Outstanding Loans and Security Agreements in our Annual Form 10-K for the fiscal year ended December 31, 2022, for discussion of our 10.25% Senior Secured Notes due March 2027 and 2.5% Green Convertible Senior Notes due August 2025. 10.25% Senior Secured Notes due March 2027 - The outstanding unpaid principal balance of $57.6 million on the 10.25% Senior Secured Notes due March 2027 was called and retired at 104% during the nine months ended September 30, 2023. The 4% premium of $2.3 million and unpaid accrued interest of $1.0 million were included in the final payment to the noteholders. We recognized loss on extinguishment of debt of $2.9 million as a result of redemption of the 10.25% Senior Secured Notes. The current and non-current balance of the outstanding unpaid principal of the 10.25% Senior Secured Notes was $12.7 million and $48.9 million as of December 31, 2022, respectively.

Interest on the 2.5% Green Notes for the three and nine months ended September 30, 2023 was $1.9 million and $5.8 million, respectively, including amortization of issuance costs of $0.5 million and $1.5 million, respectively. Interest on the 2.5% Green Notes for the three and nine months ended September 30, 2022 was $1.9 million and $5.8 million, respectively, including amortization of issuance costs of $0.5 million and $1.5 million, respectively.

Portfolio Financings

Portfolio Financings	9 Months Ended
	Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Portfolio Financings	Portfolio Financings Overview We have developed various financing options that enable customers’ use of the Energy Servers through third-party ownership financing arrangements. For additional information on these financing options, see our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. PPA V Repowering of Energy Servers PPA V was established in 2015 and we, through a special purpose subsidiary (the “Project Company”), had previously entered into certain agreements for the purpose of developing, financing, owning, operating, maintaining and managing a portfolio of 37.1 megawatts of Energy Servers. On August 10, 2023, we acquired all of Solar TC Corp’s (“Intel”) interest in PPA V, as set forth in the Purchase and Sale Agreement (the “PPA V Buyout”). The aggregate purchase price of the transaction amounted to $6.9 million. After the acquisition, PPA V became wholly owned by us. The change in our ownership interest in PPA V was accounted for as an equity transaction in accordance with ASC 810 Consolidation . The carrying amount of the noncontrolling interest was eliminated to reflect the change in our ownership interest in PPA V, and the difference between the fair value of the consideration paid and the carrying amount of the noncontrolling interest immediately prior to the PPA V Buyout of $11.5 million was recognized as additional paid-in capital in our condensed consolidated statements of stockholders’ equity (deficit). On August 24, 2023, we entered into the Membership Interest Purchase Agreement (the “MIPA”) with Generate C&I Warehouse, LLC (the “Financier”). Following the PPA V Buyout and prior to signing the MIPA, we repaid all of the outstanding debt of the Project Company of $119.0 million, including accrued interest of $0.5 million, and recognized a loss on extinguishment of debt in an amount of $1.4 million, represented in its entirety by the derecognition of the related debt issuance costs. For additional information, please see Part I, Item 1, Note 7 - Outstanding Loans and Security Agreements , Non-recourse Debt Facilities section. On August 25, 2023, we sold our 100% interest in the Project Company to the Financier through the MIPA. Simultaneously, we entered into an agreement with the Project Company to upgrade the 37.1 megawatts of old Energy Servers by replacing them with the new Energy Servers and to provide related installation services, which was financed by the Financier (the “EPC Agreement”). We also amended and restated our operations and maintenance agreement with the Project Company to cover all new Energy Servers and old Energy Servers prior to their upgrade (“the O&M Agreement”). The operations and maintenance fees under the O&M Agreement are paid on a fixed dollar per kilowatt basis. Due to our repurchase option on the old Energy Servers, the Company concluded there was no transfer of control of the old Energy Servers upon sale of the membership interest to the Financier. Accordingly, we continued to recognize the old Energy Servers, despite the legal ownership of such assets having been transferred under the MIPA. We assessed the recorded assets for impairment. The carrying amount of the PPA V property. plant and equipment was determined to be not recoverable as the net undiscounted cash flows are less than the carrying amounts for PPA V property. plant and equipment. Therefore, we recognized the asset impairment charge as electricity cost, consistent with our depreciation expense classification for property, plant and equipment under leases. The PPA V Upgrade was in progress as of September 30, 2023 and resulted in the following summarized impacts on our condensed consolidated balance sheet as of September 30, 2023: (i) cash and cash equivalents decreased by $62.4 million primarily due to a $119.0 million repayment of outstanding debt and related accrued interest, partially offset by $60.3 million from the sale of the new Energy Servers to the Project Company, (ii) property plant and equipment, net decreased by $124.0 million due to the impairment of the old Energy Servers of $123.7 million and accelerated depreciation of $0.3 million of the old Energy Servers (we revised the expected useful life of the old Energy Servers from 7.5 years to approximately 0.3 years which resulted in recognized accelerated depreciation of $0.3 million recorded in electricity cost of revenue), (iii) contract assets increased by $116.5 million and inventories decreased by $70.0 million, (iv) deferred revenue and customer deposits, current and long-term, increased by $12.4 million, (v) restricted cash, current and long-term, decreased by $8.7 million, (vi) accounts receivable, net decreased by $3.3 million, (vii) other long-term assets decreased by $1.6 million, (viii) prepaid expenses and other current assets decreased by $1.9 million, (ix) financing obligations increased by $0.3 million, and (x) accrued expenses and other current liabilities decreased by $0.5 million. Impacts on our condensed consolidated statements of operations for the three and nine months ended September 30, 2023 are summarized as follows: (i) product and installation revenue increased by $151.6 million and $9.5 million, respectively, as a result of the sale of the new Energy Servers; (ii) electricity revenue increased by $1.1 million related to the old Energy Servers, (iii) cost of electricity revenue increased by $125.5 million, primarily including the impairment of the old Energy Servers of $123.7 million and accelerated depreciation of $0.3 million prior to the completion of installation; (iv) cost of product revenue and cost of installation revenue increased by $62.6 million and $7.4 million, respectively, due to the sale of the new Energy Servers; (v) general and administrative expenses increased by $6.4 million due to the impairment of non-recoverable production insurance; (vi) loss on extinguishment of debt increased by $1.4 million, (vii) interest expense increased by $0.3 million, and (viii) net loss attributable to noncontrolling interest decreased by $1.0 million. Impacts on our consolidated statements of cash flows for the nine months ended September 30, 2023 are summarized as follows: net cash provided by financing activities decreased by $118.5 million due to the repayment of debt related to PPA V, and acquisition of all of interest in PPA V from Intel for $6.9 million net of distributions to Intel’s noncontrolling interest of $2.3 million. PPA Entity’s Aggregate Assets and Liabilities Generally, the assets of an operating company owned by an investment company can be used to settle only the operating company obligations, and the operating company creditors do not have recourse to us. The following were the aggregate carrying values of our VIE’s assets and liabilities in our condensed consolidated balance sheets, after eliminations of intercompany transactions and balances, including the PPA V Entity in the PPA V transaction as of December 31, 2022 (in thousands): December 31, 2022 Assets Current assets: Cash and cash equivalents $ 5,008 Restricted cash 550 Accounts receivable 2,072 Prepaid expenses and other current assets 1,927 Total current assets 9,557 Property, plant and equipment, net 133,285 Restricted cash 8,000 Other long-term assets 1,869 Total assets $ 152,711 Liabilities Current liabilities: Accrued expenses and other current liabilities $ 1,037 Deferred revenue and customer deposits 662 Non-recourse debt 13,307 Total current liabilities 15,006 Deferred revenue and customer deposits 4,748 Non-recourse debt 112,480 Total liabilities $ 132,234 Before the sale on August 24, 2023, we consolidated the PPA V Entity as a VIE in the PPA V transaction, as we had determined that we were the primary beneficiary of this VIE. The PPA V Entity contained debt that was non-recourse to us and owned Energy Server assets for which we did not have title.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In September 2023, as a result of a review of current strategic priorities and resource allocation, we approved a restructuring plan (the “Plan”) intended to realign our operational focus to support our multi-year growth, scale the business, and improve our cost structure and operating margins. The Plan included (i) an optimization of our workforce across multiple functions, (ii) a relocation of our repair and overhaul (“R&O”) department of our manufacturing and warehousing facility in Newark, Delaware, to Mexico, and (iii) a closure of a manufacturing, warehousing, research and development (“R&D”) facility in Sunnyvale, California. We began executing the Plan in September 2023 and expect these efforts to continue in subsequent quarters. The restructuring activities are expected to be completed in the first half of fiscal 2024, subject to local law and consultation requirements, as well as our business needs. We evaluate restructuring charges in accordance with ASC 420, Exit or Disposal Cost Obligations (“ASC 420”). According to the Plan, 74 full-time employees and 48 contractors separated from the Company in September 2023. An additional 71 full-time employees and 8 contractors separated from the Company in October 2023. Both full-time employees and contractors who were impacted by the restructuring were eligible to receive severance benefits. In the third quarter of fiscal 2023, we incurred $2.2 million in restructuring costs recorded as severance expenses. We expect to incur another $16.4 million in restructuring costs in subsequent quarters, out of which we expect $10.0 million will relate to the closure of our manufacturing, warehousing, and R&D facility in Sunnyvale, California, $3.0 million will relate to severance costs, $2.7 million will relate to relocation costs, and $0.7 million will relate to other one-time employee termination benefits. However, the actual timing and amount of costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material. The following table presents our current and non-current liability as accrued for restructuring charges on our condensed consolidated balance sheets. The table sets forth an analysis of the components of the restructuring charges and payments and other deductions made against the accrual for the three months ended September 30, 2023 (in thousands): Three Months Ended, September 30, 2023 Severance Balance at June 30, 2023 $ — Restructuring accruals 2,219 Payments (1,047) Balance at September 30, 2023 $ 1,172 Severance expense recorded in the third quarter of fiscal 2023 in accordance with ASC 420 was a result of the separation of 74 full-time employees and 48 contractors associated with the Plan. At September 30, 2023, $1.2 million of accrued severance-related costs were included in accrued expenses and other current liabilities in our condensed consolidated balance sheets. The following table summarizes restructuring costs included in the accompanying condensed consolidated statements of operations (in thousands): Three Months Ended, September 30, 2023 Cost of product revenue $ 677 Cost of service revenue 48 Operating expenses: Sales and marketing 1,387 General and administrative 107 Total $ 2,219

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments Purchase Commitments with Suppliers and Contract Manufacturers - In order to reduce manufacturing lead-times for an adequate supply of inventories, we have agreements with our component suppliers and contract manufacturers to allow long lead-time component inventory procurement based on a rolling production forecast. We are contractually obligated to purchase long lead-time component inventory procured by certain manufacturers in accordance with our forecasts. We can generally give notice of order cancellation at least 90 days prior to the delivery date. However, we occasionally issue purchase orders to our component suppliers and third-party manufacturers that may not be cancellable. As of September 30, 2023 and December 31, 2022, we had no material open purchase orders with our component suppliers and third-party manufacturers that are not cancellable. Performance Guarantees - We guarantee the performance of Energy Servers at certain levels of output and efficiency to our customers over the contractual term. We monitor the need for any accruals arising from such guaranties, which are calculated as the difference between committed and actual power output or between natural gas consumption at warranted efficiency levels and actual consumption, multiplied by the contractual rates with the customer. Amounts payable under these guaranties are accrued in periods when the guaranties are not met and are recorded as service revenue in the condensed consolidated statements of operations. We paid $4.5 million and $24.4 million for the three and nine months ended September 30, 2023, respectively, for such performance guarantees. We paid $0.8 million and $10.5 million for the three and nine months ended September 30, 2022, respectively, for such performance guarantees. Letters of Credit - In 2019, pursuant to the PPA II upgrade of Energy Servers, we agreed to indemnify our financing partner for losses that may be incurred in the event of certain regulatory, legal or legislative developments and established a cash-collateralized letter of credit facility for this purpose. As of September 30, 2023 and December 31, 2022, the balance of this cash-collateralized letter of credit was $40.4 million and $69.1 million, respectively. In August 2023, as part of the PPA V Upgrade, the debt service reserve of $8.6 million was reclassified from restricted cash to cash and cash equivalents at the time of repayment of the 3.04% Senior Secured Notes due June 2031. For additional information, please see Part I, Item 1, Note 7 – Outstanding Loans and Security Agreements and Note 10 – Portfolio Financings . The restricted cash held in the PPA V entity as of December 31, 2022, was $8.6 million. In addition, we have other outstanding letters of credit issued to our customers and other counterparties in the U.S. and international locations under different performance and financial obligations. These letters of credit are collateralized through cash deposited in the controlled bank accounts with the issuing banks, and are classified as restricted cash in our condensed consolidated balance sheets. In September 2023, we canceled certain existing cash-collateralized letters of credit with an approximate value of $60.4 million issued to our customers in the Republic of Korea under long-term service agreements (the “LTSAs”), and replaced them with surety bonds on a non-collateralized basis. As of September 30, 2023 and December 31, 2022, the balances of the cash-collateralized letters of credit issued to our customers and other counterparties in the U.S. and international locations were $32.3 million and $84.3 million, respectively. Pledged Funds - In 2019, pursuant to the PPA IIIb upgrade of Energy Servers, we established a restricted cash fund of $20.0 million, which had been pledged for a seven-year period to secure our operations and maintenance obligations with respect to the totality of our obligations to the financier. All or a portion of such funds would be released if we meet certain credit rating and/or market capitalization milestones prior to the end of the pledge period. If we do not meet the required criteria within the first five-year period, the funds would still be released to us over the following two years as long as the Energy Servers continue to perform in compliance with our warranty obligations. As of September 30, 2023 and December 31, 2022, the balance of the restricted cash fund was $7.6 million and $7.9 million, respectively. Contingencies Indemnification Agreements - We enter into standard indemnification agreements with our customers and certain other business partners in the ordinary course of business. Our exposure under these agreements is unknown because it involves future claims that may be made against us but have not yet been made. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations. Delaware Economic Development Authority - In March 2012, we entered into an agreement with the Delaware Economic Development Authority (the “Authority”) to provide a grant of $16.5 million to us as an incentive to establish a new manufacturing facility in Delaware and to provide employment for full time workers at the facility over a certain period of time. The approved grant consisted of two components - a performance grant of $12.0 million that was received in 2012-2013 and was tied to total compensation paid to full time workers and a supplier incentive grant of $4.5 million that we would have received if we had employed 900 full time employees by pre-established dates. We forfeited the entire $4.5 million supplier incentive component of the grant. We forfeited and repaid two portions of the performance grant based on our achievement of one out of three milestones for the total compensation paid to full time workers, as follows: ■ $108 million in total compensation over the four-year period ended September 30, 2017, which we did not meet, requiring us to repay $1.5 million of the grant, ■ $144 million in total compensation over the four-year period ended September 30, 2021, which we did not meet, requiring us to repay $1.0 million of the grant, and ■ $72 million in total compensation over the two-year period ended September 30, 2023, which we met, so no repayment was required. We account for grants by analogizing to the grant accounting model under IAS 20, Accounting for Government Grants and Disclosure of Government Assistance (“IAS 20”). As of December 31, 2022, we recorded $9.5 million of grant related liability in accrued expenses and other current liabilities for future repayment of the grant. As of September 30, 2023, we concluded there was reasonable assurance that we had met the grant requirements, and as such, the grant related liability of $9.5 million was recognized in (a) the condensed consolidated statements of operations as a reduction in (i) cost of product revenue of $3.1 million, (ii) cost of service revenue of $2.9 million, (iii) general and administrative expenses of $0.6 million, (iv) research and development expenses of $0.5 million, and (v) sales and marketing expenses of $0.2 million for the three months ended September 30, 2023, and in (b) the condensed consolidated balance sheets as of September 30, 2023 as a reduction of inventories of $2.2 million, which is represented by capitalized payroll expenses and will be realized in the condensed consolidated statements of operations in future periods upon sale of these inventories. Investment Tax Credits - Our Energy Servers are eligible for federal investment tax credits (“ITCs”) that accrued to qualified property under Internal Revenue Code Section 48 when placed into service. However, the ITC program has operational criteria that extend for five years. If the energy property is disposed of or otherwise ceases to be qualified investment credit property before the close of the five-year recapture period is fulfilled, it could result in a partial reduction of the incentives. Legal Matters - We are involved in various legal proceedings that arise in the ordinary course of business. We review all legal matters at least quarterly and assess whether an accrual for loss contingencies needs to be recorded. We record an accrual for loss contingencies when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Legal matters are subject to uncertainties and are inherently unpredictable, so the actual liability in any such matters may be materially different from our estimates. If an unfavorable resolution were to occur, there exists the possibility of a material adverse impact on our condensed consolidated balance sheets, results of operations or cash flows for the period in which the resolution occurs or in future periods. In March 2019, the Lincolnshire Police Pension Fund filed a class action complaint in the Superior Court of the State of California, County of Santa Clara, against us, certain members of our senior management, certain of our directors and the underwriters in our July 25, 2018 IPO alleging violations under Sections 11 and 15 of the Securities Act for alleged misleading statements or omissions in our Registration Statement on Form S-1 filed with the SEC in connection with the IPO. Two related class action cases were subsequently filed in the Santa Clara County Superior Court against the same defendants containing the same allegations; Rodriquez vs Bloom Energy et al. was filed on April 22, 2019 and Evans vs Bloom Energy et al. was filed on May 7, 2019. These cases have been consolidated. Plaintiffs’ consolidated amended complaint was filed with the court on September 12, 2019. On October 4, 2019, defendants moved to stay the lawsuit pending the federal district court action discussed below. On December 7, 2019, the Superior Court issued an order staying the action through resolution of the parallel federal litigation mentioned below. We believe the complaint to be without merit and in contravention of our forum selection clause in our Restated Certificate of Incorporation and we intend to defend this action vigorously. We are unable to estimate any range of reasonably possible losses. In May 2019, Elissa Roberts filed a class action complaint in the federal district court for the Northern District of California against us, certain members of our senior management team, and certain of our directors alleging violations under Sections 11 and 15 of the Securities Act for alleged misleading statements or omissions in our Registration Statement on Form S-1 filed with the SEC in connection with the IPO. On September 3, 2019, the court appointed a lead plaintiff and lead plaintiffs’ counsel. On November 4, 2019, plaintiffs filed an amended complaint adding the underwriters in the IPO and our auditor as defendants for the Section 11 claim, as well as adding claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), against us, and certain members of our senior management team. The amended complaint alleged a class period for all claims from the time of our IPO until September 16, 2019. On April 21, 2020, plaintiffs filed a second amended complaint, which continued to make the same claims and added allegations pertaining to the restatement and, as to claims under the Exchange Act, extended the putative class period through February 12, 2020. On July 1, 2020, we and the other defendants filed motions to dismiss the second amended complaint. On September 29, 2021, the court entered an order dismissing with leave to amend (1) five of seven statements or groups of statements alleged to violate Sections 11 and 15 of the Securities Act and (2) all allegations under the Exchange Act. All allegations against our auditors were also dismissed. Plaintiffs elected not to amend the complaint and instead on October 22, 2021 filed a motion for entry of final judgment in favor of our auditors so that plaintiffs could appeal the dismissal of those claims. The court denied that motion on December 1, 2021 and in response plaintiffs filed a motion asking the court to certify an interlocutory appeal as to the accounting claims. The court denied plaintiffs’ motion on April 14, 2022. The claims for violation of Sections 11 and 15 of the Securities Act that were not dismissed by the court entered the discovery phase. On January 6, 2023, Bloom and the plaintiffs’ entered into an agreement in principle to settle the claims against Bloom, its executives and directors, and the IPO underwriters for a payment of $3 million, which we expect to be funded entirely by our insurers. If the settlement becomes effective, we expect it to result in a dismissal with prejudice of all claims against us, our executives and directors, and the underwriters. The settlement does not constitute an acknowledgement of liability or wrongdoing. On June 30, 2023, Bloom and the plaintiff’s executed a definitive settlement agreement containing the foregoing terms and customary terms for class action settlements, and on the same date, filed the settlement agreement with the court to seek its approval. The judge issued a preliminary approval of the settlement on October 31, 2023. In June 2021, we filed a petition for writ of mandate and a complaint for declaratory and injunctive relief in the Santa Clara Superior Court against the City of Santa Clara for failure to issue building permits for two of our customer installations and asking the court to require the City of Santa Clara to process and issue the building permits. In October 2021, we filed an amended petition and complaint that asserts additional constitutional and tort claims based on the City’s failure to timely issue the Energy Server permits. Discovery has commenced and we are aggressively pursuing all claims. On February 4, 2022, the City of Santa Clara filed a demurrer seeking to dismiss all of the Company’s claims. The trial judge rejected the demurrer on all claims except one, and allowed Bloom leave to amend that claim. The second amended petition was filed on July 5, 2022. The City of Santa Clara demurred only to the amended cause of action seeking damages for tortious conduct. The trial judge granted that demurrer and struck the tort claim on October 27, 2022; the writ of mandate and constitutional claims were allowed to proceed. The parties are currently briefing the writ of mandate claims which seek immediate issuance of the building permits. On April 21, 2023, the parties executed a settlement agreement which allows our two pending customer installations to proceed under building permits and requires the City to amend its zoning code so that future installations of Bloom Energy Servers in Santa Clara require only building permits. In February 2022, Plansee SE/Global Tungsten & Powders Corp. (“Plansee/GTP”), a former supplier, filed a request for expedited arbitration with the World Intellectual Property Organization Arbitration and Mediation Center in Geneva Switzerland (“WIPO”), for various claims allegedly in relation to an Intellectual Property and Confidential Disclosure Agreement between Plansee/GTP and Bloom Energy Corporation. Plansee/GTP’s statement of claims includes allegations of infringement of U.S. Patent Nos. 8,802,328, 8,753,785 and 9,434,003. On April 3, 2022, we filed a complaint against Plansee/GTP in the Eastern District of Texas to address the dispute between Plansee/GTP and Bloom Energy Corporation in a proper forum before a U.S. Federal District Court. Our complaint seeks the correction of inventorship of U.S. Patent Nos. 8,802,328, 8,753,785 and 9,434,003 (the “Patents-in-Suit”); declaratory judgment of invalidity, unenforceability, and non-infringement of the Patents-in-Suit; and declaratory judgment of no misappropriation. Further, our complaint seeks to recover damages we have suffered in relation to Plansee/GTP’s business dealings that, as alleged, constitute acts of unfair competition, tortious interference contract, breach of contract, violations of the Racketeer Influenced and Corrupt Organizations (RICO) Act and violations of the Clayton Antitrust Act. On June 9, 2022, Plansee/GTP filed a motion to dismiss the complaint filed in the Eastern District of Texas and compel arbitration (or alternatively to stay). We filed our opposition on June 30, 2022, Plansee/GTP filed its reply on July 14, 2022 and we filed our sur-reply on July 22, 2022. On February 9, 2023, Magistrate Judge Payne issued a report and recommendation to stay the district court action pending an arbitrability determination by the arbitrator for each claim. On February 23, 2023, we filed an amended complaint adding additional causes of action and filed objections to the Magistrate’s report and recommendation. On April 26, 2023, Judge Gilstrap overruled our objections to the Magistrate’s report and recommendation and stayed the district court action pending arbitrability determinations by the arbitrator in the WIPO proceeding. The arbitration had been held in abeyance awaiting the District Court’s decision. A hearing by the arbitrator in WIPO on arbitrability took place on June 27, 2023. Further proceedings in the arbitration are confidential pursuant to the WIPO rules. Given that the WIPO arbitration had been held in abeyance, the arbitration is in an early stage. We are unable to predict the ultimate outcome of the arbitration at this time.

For the three and nine months ended September 30, 2022, we recorded an income tax benefit and income tax provision of $0.3 million and $0.9 million, respectively, on pre-tax losses of $60.1 million and $263.4 million for effective tax rates of (0.6)% and (0.3)%, respectively. The effective tax rate for the three and nine months ended September 30, 2023 and 2022 was lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets.

Equity Method Investments and Joint Ventures [Abstract]
SK ecoplant Strategic Investment	SK ecoplant Strategic Investment In October 2021, we expanded our existing relationship with SK ecoplant. As part of this arrangement, we amended the previous Preferred Distribution Agreement (“PDA”) and Joint Venture Agreement (“JVA”) with SK ecoplant. The restated PDA establishes SK ecoplant’s purchase commitments for our Energy Servers for the three year period on a take or pay basis as well as the basis for determining the prices at which the Energy Servers and related components will be sold. The restated JVA increases the scope of assembly done by the joint venture facility in the Republic of Korea, which was established in 2019, for the procurement of local parts for our Energy Servers and the assembly of certain portions of the Energy Servers for the South Korean market. The joint venture is a VIE of Bloom and we consolidate it in our financial statements as we are the primary beneficiary and therefore have the power to direct activities which are most significant to the joint venture. On September 15, 2023, we entered into the Amended and Restated JVA and the Share Purchase Agreement (together, the “Amended JV Agreements”) with SK ecoplant which changed the share of our voting rights in the Korean joint venture to 40% and increases the scope of assembly done by the joint venture facility in the Republic of Korea to full assembly. Neither the Amended JV Agreements, nor the fact that SK ecoplant is considered to be our related party after the conversion of Series B RCPS into shares of our Class A common stock (for additional information, please see Part I, Item 1, Note 11 - Related Party Transactions ) changed our status as the primary beneficiary of the Korean joint venture. Therefore, we continue to consolidate this VIE in our financial statements as of September 30, 2023. The following are the aggregate carrying values of the Korean joint venture’s assets and liabilities in our condensed consolidated balance sheets, after eliminations of intercompany transactions and balances, as of September 30, 2023 and December 31, 2022 (in thousands): September 30, December 31, 2023 2022 Assets Current assets: Cash and cash equivalents $ 1,012 $ 2,591 Accounts receivable 20,483 4,257 Inventories 10,617 13,412 Prepaid expenses and other current assets 1,574 2,645 Total current assets 33,686 22,905 Property and equipment, net 1,705 1,141 Operating lease right-of-use assets 2,249 2,390 Other long-term assets 44 47 Total assets $ 37,684 $ 26,483 Liabilities Current liabilities: Accounts payable $ 4,828 $ 5,607 Accrued expenses and other current liabilities 3,324 1,355 Deferred revenue and customer deposits — 2 Operating lease liabilities 409 393 Total current liabilities 8,561 7,357 Operating lease liabilities 1,665 2,000 Non-recourse debt 1,483 — Total liabilities $ 11,709 $ 9,357 In October 2021, we also entered into a new Commercial Cooperation Agreement (the “CCA”) regarding initiatives pertaining to the hydrogen market and general market expansion for our products. The Initial Investment In October 2021, we entered into the SPA pursuant to which we agreed to sell and issue to SK ecoplant 10,000,000 shares of Series A RCPS, par value $0.0001 per share, at a purchase price of $25.50 per share for an aggregate purchase price of $255.0 million. On December 29, 2021, the closing of the sale of the Series A RCPS was completed and we issued the 10,000,000 shares of the Series A RCPS (the “Initial Investment”). In addition to the Initial Investment, the SPA provided SK ecoplant with an option to acquire a variable number of shares of Class A Common Stock (the “Option”). According to the SPA, SK ecoplant was entitled to exercise the Option through August 31, 2023, and the transaction must have been completed by November 30, 2023. The sale of Series A RCPS was recorded at its fair value of $218.0 million on the date of issuance. Accordingly, we allocated the excess of the cash proceeds received of $255.0 million plus the change in fair value of the Series A RCPS between October 23, 2021, and December 29, 2021, of $9.7 million, over the fair value of the Series A RCPS on December 29, 2021, and the fair value of the Option on October 23, 2021, to the PDA. This excess amounted to $37.0 million and was recorded in deferred revenue and customer deposits. Accordingly, during the three and nine months ended September 30, 2022, we recognized product revenue of $3.2 million and $7.9 million, respectively, in connection with this arrangement. No product revenue was recognized during the three and nine months ended September 30, 2023 in connection with this arrangement. As of December 31, 2022, the unrecognized amount of $24.6 million included $10.0 million in current deferred revenue and customer deposits and $14.6 million in non-current deferred revenue and customer deposits on the condensed consolidated balance sheets. As of September 30, 2023, the unrecognized amount of deferred revenue and customer deposits was reduced to zero as a result of the Second Tranche Closing (see details below in section “The Second Tranche Closing”). PDA, JVA, CCA and the SPA entered into with SK ecoplant concurrently were evaluated as a combined contract in accordance with ASC 606 Revenue from Contracts with Customers and, to the extent applicable for separated components, under the guidance of Topic 815 Derivatives and Hedging and applicable subsections and ASC 480 Distinguishing Liabilities from Equity . We concluded that the Option was a freestanding financial instrument that should have been separately recorded at fair value on the date the SPA was executed. On August 10, 2022, pursuant to the SPA, SK ecoplant notified us of its intent to exercise its option to purchase additional shares of our Class A common stock, pursuant to a Second Tranche Exercise Notice (as defined in the SPA) electing to purchase 13,491,701 shares at a purchase price of $23.05 per share (the “Second Tranche Closing”). As of December 31, 2022, this option was accounted for as the equity-classified forward contract. For further information, see Part II, Item 8, Note 17 - SK ecoplant Strategic Investment in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. The Second Tranche Closing On March 20, 2023, SK ecoplant entered into the Amended SPA with us, pursuant to which on March 23, 2023, we issued and sold to SK ecoplant 13,491,701 shares of non-voting Series B RCPS, par value $0.0001 per share, at a purchase price of $23.05 per share for cash proceeds of $311.0 million, excluding issuance cost of $0.5 million. The Amended SPA triggered the modification of the equity-classified forward contract on Class A common stock, which resulted in the derecognition of the pre-modification fair value of the forward contract given to SK ecoplant of $76.2 million. The derecognition of the pre-modification fair value was recorded in additional paid-in capital in our condensed consolidated balance sheets as of September 30, 2023. The Series B RCPS was accounted for as a stock award with liability and equity components. The liability component of the Series B RCPS was recognized at the redemption value of $311.0 million, less issuance costs of $0.5 million, and the equity component of the Series B RCPS was recognized at its fair value of $16.1 million on March 20, 2023 and recorded in current liabilities and additional paid-in capital, respectively, in our condensed consolidated balance sheets as of September 30, 2023. On March 20, 2023, in connection with the Amended SPA we also entered into the Loan Agreement, pursuant to which we had the option to draw on a loan from SK ecoplant with a maximum principal amount of $311.0 million, a maturity of five years and an interest rate of 4.6%, should SK ecoplant have sent a redemption notice to us under the Amended SPA. The Amended SPA and the Loan Agreement provided us with cash proceeds of $311.0 million and a loan commitment asset of $52.8 million from SK ecoplant for total consideration of $363.8 million. In return, SK ecoplant received consideration of $403.3 million, consisting of the release from the obligation to close on the original transaction fair valued at $76.2 million, the obligation from us to issue the Series B RCPS at redemption value of $311.0 million, and the option to convert the Series B RCPS to Class A common stock, which had an estimated fair value of $16.1 million. The excess consideration provided by us amounted to $39.5 million, which resulted in a reduction of our deferred revenue and customer deposits by $24.6 million related to the Initial Investment, as of September 30, 2023. The net excess consideration of $14.9 million was recognized as $8.2 million in prepaid expenses and other current assets and $6.7 million was classified as other long-term assets in our condensed consolidated balance sheets as of March 31, 2023. The deferred expense is recognized as contra-revenue over the take or pay period based on an estimate of the revenue we expect to receive under the remaining term of the PDA. During the three and nine months ended September 30, 2023, the deferred expense recognized as contra-revenue was $3.0 million. As a result, as of September 30, 2023, we recognized the net excess consideration of $11.9 million, of which $9.9 million was classified as prepaid expenses and other current assets and $2.0 million was classified as other long-term assets, in our condensed consolidated balance sheet. On September 23, 2023, all 13,491,701 shares of the Series B RCPS were automatically converted into shares of our Class A common stock pursuant to the Certificate of Designation, dated as of March 20, 2023, setting forth the rights, preferences, privileges, and restrictions of the Series B RCPS, as amended by the Certificate of Amendment to the Certificate of Designation, dated as of April 18, 2023. As a result of the conversion: (i) the liability component of the Series B RCPS of $310.5 million was reclassified to additional paid-in capital, less par value of the issued 13,491,701 shares of our Class A common stock, and (ii) the loan commitment asset was recorded at its fair value of $52.8 million, of which $5.3 million was classified as current and $47.5 million was classified as non-current in our condensed consolidated balance sheets, and was expensed immediately and recognized in interest expense in our condensed consolidated statements of operations. Upon conversion of all Series B RCPS into shares of our Class A common stock, SK ecoplant is considered to be a related party.
