Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 extensions and conversions to equit y that we completed during 2021, 2022 and the first quarter of 2023, we had $282.4 million of total outstanding recourse debt as of March 31, 2023, $269.4 million of which was classified as long-term debt. Our scheduled recourse debt repayments commenced in June 2022. 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 15 - 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 may draw down on a loan from SK ecoplant with a maximum principal amount of $311.0 million, should SK ecoplant send a redemption notice to us under the Amended SPA or otherwise reduce any portion of its current holdings of our Class A stock. The Loan Agreement has a maturity of five years and bears an interest rate of 4.6%. The proceeds of the loan may be used by us for working capital and general corporate purpose needs. Our future capital requirements will 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 US on our ongoing and future operations. The rising interest rate environment in the US has and will 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 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”). Certain prior period amounts have been reclassified to conform to the current period presentation. 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 and long-lived assets were attributable to operations in the United States for all periods presented. In addition to shipments in the US, we also ship our Energy Servers to other countries, primarily to the Republic of Korea, Japan and India (collectively, the “Asia Pacific region”). In the three months ended March 31, 2023 and 2022, total revenue in the Asia Pacific region was 5% and 65%, respectively, of our total revenue. Credit Risk - At March 31, 2023, two customers accounted for approximately 70% 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 March 31, 2023, revenue from two customers accounted for approximately 41% and 25% of our total revenue. During the three months ended March 31, 2022, two customers each represented approximately 32% 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): March 31, December 31, 2023 2022 Accounts receivable $ 329,757 $ 250,995 Contract assets 47,778 46,727 Customer deposits 89,741 121,085 Deferred revenue 87,848 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 March 31, 2023 there were no customer deposits related to transactions with SK ecoplant (see Note 15 - 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 2023 2022 Beginning balance $ 46,727 $ 25,201 Transferred to accounts receivable from contract assets recognized at the beginning of the period (10,787) (14,576) Revenue recognized and not billed as of the end of the period 11,838 2,908 Ending balance $ 47,778 $ 13,533 Deferred Revenue Deferred revenue activity, including deferred incentive revenue activity, during the three months ended March 31, 2023 and 2022 consisted of the following (in thousands): Three Months Ended 2023 2022 Beginning balance $ 94,355 $ 115,476 Additions 224,939 166,676 Revenue recognized (231,446) (178,663) Ending balance $ 87,848 $ 103,489 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 will 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.

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 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 for the PPA Entity in the PPA V transaction as of March 31, 2023 and December 31, 2022 (in thousands): March 31, December 31, 2023 2022 Assets Current assets: Cash and cash equivalents $ 1,815 $ 5,008 Restricted cash 350 550 Accounts receivable 1,820 2,072 Prepaid expenses and other current assets 1,322 1,927 Total current assets 5,307 9,557 Property, plant and equipment, net 129,722 133,285 Restricted cash 8,000 8,000 Other long-term assets 1,742 1,869 Total assets $ 144,771 $ 152,711 Liabilities Current liabilities: Accrued expenses and other current liabilities $ 19 $ 1,037 Deferred revenue and customer deposits 662 662 Non-recourse debt 11,435 13,307 Total current liabilities 12,116 15,006 Deferred revenue and customer deposits 4,585 4,748 Non-recourse debt 108,564 112,480 Total liabilities $ 125,265 $ 132,234 We consolidated the PPA Entity as a VIE in the PPA V transaction, as we have determined that we are the primary beneficiary of this VIE.

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended
	Mar. 31, 2023
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 and to ensure 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 issue purchase orders to our component suppliers and third-party manufacturers that may not be cancellable. As of March 31, 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 contra service revenue in the condensed consolidated statements of operations. We paid $15.8 million and $0.3 million for the three months ended March 31, 2023 and 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 development and established a cash-collateralized letter of credit facility for this purpose. As of March 31, 2023, the balance of this cash-collateralized letter of credit was $54.7 million, of which $33.3 million and $21.4 million is recognized as short-term and long-term restricted cash, respectively. As of December 31, 2022, the balance of this cash-collateralized letter of credit was $69.1 million, of which $40.6 million and $28.5 million is recognized as short-term and long-term restricted cash, 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 March 31, 2023 and December 31, 2022, the balance of the long-term restricted cash fund was $6.7 million and $6.7 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 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. We have so far received $12.0 million of the grant, which is contingent upon meeting the milestones through September 30, 2023. In the event that we do not meet the milestones, we may have to repay the Delaware Economic Development Authority, up to an additional $2.5 million on September 30, 2023. We repaid $1.5 million and $1.0 million of the grant in 2017 and 2021, respectively. As of September 30, 2022 the grant became current, and we have recorded $9.5 million in accrued expenses and other current liabilities for future repayments of this grant as of March 31, 2023 and December 31, 2022, respectively. Investment Tax Credits - Our Energy Servers are eligible for federal 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. Energy Servers are purchased by the PPA Entities, other financial sponsors, or customers and, therefore, these parties bear the risk of repayment if the assets placed in service do not meet the ITC operational criteria in the future although in certain limited circumstances we do provide indemnification for such risk. 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 of 1933, as amended (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 will be funded entirely by our insurers. If the settlement becomes effective, it will 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. This settlement is conditioned on the execution of a definitive settlement agreement containing the foregoing terms and customary terms for class action settlements, and approval of the settlement by the court. If the court does not approve the settlement and all of its material terms, or the settlement does not otherwise become final or effective, proceedings in the action will continue. 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. Given that the District Court matter is stayed and the WIPO arbitration had been held in abeyance, the cases are still in their early stages. We are unable to predict the ultimate outcome of the arbitration and district court action at this time.

The effective tax rate for the three months ended March 31, 2023 and 2022 is 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. 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 March 31, 2023 and December 31, 2022 (in thousands): March 31, December 31, 2023 2022 Assets Current assets: Cash and cash equivalents $ 902 $ 2,591 Accounts receivable — 4,257 Inventories 14,524 13,412 Prepaid expenses and other current assets 1,070 2,645 Total current assets 16,496 22,905 Property and equipment, net 1,081 1,141 Operating lease right-of-use assets 2,332 2,390 Other long-term assets 47 47 Total assets $ 19,956 $ 26,483 Liabilities Current liabilities: Accounts payable $ 1,105 $ 5,607 Accrued expenses and other current liabilities 685 1,355 Deferred revenue and customer deposits 5 2 Operating lease liabilities 396 393 Total current liabilities 2,191 7,357 Operating lease liabilities 1,945 2,000 Total liabilities $ 4,136 $ 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 Simultaneous with the execution of the above agreements, we entered into the SPA pursuant to which we agreed to sell and issue to SK ecoplant 10,000,000 shares of Series A redeemable convertible preferred stock (the “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 is recognized as revenue over the take or pay period based on an estimate of the revenue we expect to receive under the PDA. Accordingly, during the three months ended March 31, 2022, we recognized Product Revenue of $1.2 million in connection with this arrangement. No Product Revenue was recognized during the three months ended March 31, 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 March 31, 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”). Upon receipt of SK’s notice the purchase price and the number of shares of Class A Common Stock that SK will purchase under the Option became fixed. Upon the receipt of the notice from SK ecoplant the Option met the criteria of an equity award and was classified as a forward contract as part of additional paid-in capital. On November 8, 2022, each share of the Series A RCPS was converted into 10,000,000 shares of Class A Common Stock. On December 6, 2022, SK ecoplant and Bloom mutually agreed to delay the Second Tranche Closing Date for the purchase of the 13,491,701 shares of Class A Common Stock of the Issuer until March 31, 2023, unless an earlier date is mutually agreed upon and subject to and assuming the satisfaction of applicable regulatory clearance. The mutual agreement to modify the Second Tranche Closing date did not change the accounting or valuation of the equity-classified forward recorded. 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 redeemable convertible preferred stock, par value $0.0001 per share (the “Series B RCPS”), at a purchase price of $23.05 per share for cash proceeds of $311.0 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 March 31, 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 and the equity component of the Series B RCPS was recognized at its fair value of $16.1 million on March 20, 2023, and these were recorded in current liabilities and additional paid-in capital, respectively, in our condensed consolidated balance sheets as of March 31, 2023. On March 20, 2023, in connection with the Amended SPA, we also entered into the Loan Agreement, pursuant to which we have the option to draw on a loan from SK ecoplant with a maximum principal amount of $311.0 million, should SK ecoplant send a redemption notice to us under the Amended SPA. The Loan Agreement has a maturity of five years and bears an interest rate of 4.6%. The Loan Agreement is a freestanding financial instrument; accordingly, we recognized a loan commitment asset 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 as of March 31, 2023. 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, comprising 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 has 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 March 31, 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 will be 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. Description of Series B RCPS - The significant rights and preferences of the Series B RCPS are as follows: Liquidation: Upon the liquidation or dissolution of Bloom, or a deemed liquidation event (which includes a change in control or the sale or other disposition of all or substantially all of our assets), the holders of the Series B RCPS are entitled to receive in preference to the holders of the Common Stock, the greater of (i) their liquidation preference or (ii) an amount they would be entitled to receive on an as-converted basis. After payment of the liquidation preference to the holders of the Series B RCPS, our remaining assets are available for distribution to the holders of Common Stock on a pro rata basis. Redemption rights: The Series B RCPS may be redeemed upon election of SK ecoplant at the redemption price per share of $311.0 million divided by the number of then outstanding shares of Series B RCPS, which shall be payable in one installment, commencing on a date not less than sixty days after and not more than ninety days after SK ecoplant deliver written notice of the redemption to the Company (the “Redemption Notice”). SK ecoplant shall not send the Redemption Notice until four months have passed from the Series B RCPS issue date and the delivery of the Redemption Notice shall be irrevocable. The Series B RCPS shall not be redeemable upon the election of the Company. Conversion: The Series B RCPS are convertible at any time at SK ecoplant’s option into Class A common stock (subject to adjustment in the event of stock splits or combinations, and dividends or other distributions on the Class A Common Stock which are payable in shares of Class A Common Stock). In addition, on the 6-month anniversary of the issuance date, the Series B RCPS shall automatically convert into shares of Class A common stock at the conversion price in effect at that time. The automatic conversion will not occur should SK ecoplant elect to redeem the Series B RCPS prior to six months after the original issuance date, but not earlier than four months have passed from the original issue date. Protective provisions: Bloom is prohibited from the following actions without the affirmative vote of a majority of the holders of the Series B RCPS: (i) increasing the authorized number of shares of Series B RCPS; (ii) authorizing or creating any new class of stock that is senior to or on a parity with the Series B RCPS or increasing or decreasing the authorized number of shares of any such new class of stock; (iii) amending the rights, preferences or privileges of the Series B RCPS; and (iv) redeeming the Series B RCPS. Voting and dividend rights: The holders of the Series B RCPS have no voting rights, except on matters related to the RCPS, and are not entitled to dividends.
