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, 2023. 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 equity that we completed since 2021, we had $1,121.0 million and $4.3 million of total outstanding recourse and non-recourse debt, respectively, as of June 30, 2024, which was classified as long-term debt. On May 29, 2024, we issued 3% Green Convertible Senior Notes (the “3% Green Notes due June 2029”) in an aggregate principal amount of $402.5 million due June 2029, unless earlier repurchased, redeemed or converted, less the initial purchasers’ discount of $12.1 million and other issuance costs of $0.7 million, resulting in net proceeds of $389.7 million. On May 29, 2024, we used approximately $141.8 million of the net proceeds from this issuance to repurchase $115.0 million, or 50%, of the outstanding principal amount of our 2.5% Green Convertible Senior Notes due August 2025 (the “2.5% Green Notes”) in privately negotiated transactions. The repurchase amount equaled 122.6% of the principal amount repurchased, plus related accrued and unpaid interest. 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 working capital, the expansion of sales and marketing activities both in domestic and international markets, market acceptance of our products, our ability to secure financing for customer use of our Energy Servers, the timing of installations and of inventory build in anticipation of future sales and installations, and overall economic conditions. In order to support and achieve our future growth plans, we may need or seek advantageously to obtain additional funding through equity or debt financing. Failure to obtain this financing in future quarters may affect our financial position and results of operations, including our revenues and cash flows. 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 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, 2023. Basis of Presentation We have prepared the unaudited 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, 2023. 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, 2023. Concentration of Risk Geographic Risk — The majority of our revenue and long-lived assets are attributable to operations in the U.S. for all periods presented. In addition to shipments in the U.S., we also ship our Energy Servers to other countries, primarily, the Republic of Korea, Japan, India and Taiwan (collectively referred to as the “Asia Pacific region”). For the three and six months ended June 30, 2024, total revenue in the U.S. was 83% and 65%, respectively, of our total revenue. For the three and six months ended June 30, 2023, total revenue in the U.S. was 73% and 83%, respectively, of our total revenue. Credit Risk — At June 30, 2024, two customers, the first of which is our related party (see Note 10 — Related Party Transactions ), accounted for approximately 66% and 20% of accounts receivable, respectively. At December 31, 2023, one customer that is our related party accounted for approximately 74% of accounts receivable. Customer Risk — During the three months ended June 30, 2024, revenue from two customers, the second of which is our related party (see Note 10 — Related Party Transactions ), accounted for approximately 36.0% and 26.0% of our total revenue, respectively. During the six months ended June 30, 2024, two customers, the first of which is our related party (see Note 10 — Related Party Transactions ), represented approximately 37.0% and 27.0% of our total revenue, respectively. During the three months ended June 30, 2023, revenue from three customers accounted for approximately 39%, 22%, and 12% of our total revenue. During the six months ended June 30, 2023, three customers represented approximately 40%, 13%, and 12% 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): June 30, December 31, 2024 2023 Accounts receivable $ 524,000 $ 340,740 Contract assets 90,388 41,366 Customer deposits 84,656 75,734 Deferred revenue 55,965 72,328 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 control of performance obligations. 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.

The 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 Servers. 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 Six Months Ended 2024 2023 2024 2023 Revenue from contracts with customers: Product revenue $ 226,308 $ 214,706 $ 379,672 $ 408,451 Installation revenue 42,733 24,321 54,177 44,846 Services revenue 52,531 42,298 108,991 82,961 Electricity revenue 4,893 3,966 9,641 7,804 Total revenue from contract with customers 326,465 285,291 552,481 544,062 Revenue from contracts that contain leases: Electricity revenue 9,302 15,804 18,584 32,224 Total revenue $ 335,767 $ 301,095 $ 571,065 $ 576,286

We derecognized $59.6 million of accounts receivable during the six months ended June 30, 2023, and no accounts receivable were derecognized during the three months ended June 30, 2023. The cost of factoring such accounts receivable on our condensed consolidated statements of operations for the three and six months ended June 30, 2024, was $0.5 million and $2.4 million, respectively. The costs of factoring for the six months ended June 30, 2023, were $0.7 million. There were no costs of factoring for the three months ended June 30, 2023.

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 six months ended June 30, 2024, were as follows (in thousands): Embedded EPP Derivative Liability Liabilities at December 31, 2023 $ 4,376 Changes in fair value (70) Liabilities at June 30, 2024 $ 4,306 For more details on EPP derivatives, refer to Part II, Item 8 Note 5 — Fair Value in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 .

Non-recourse debt refers to debt that is recourse to only our subsidiary, Bloom SK Fuel Cell, LLC, a joint venture in the Republic of Korea with SK ecoplant (the “Korean JV”). The differences between the unpaid principal balances and the net carrying values apply to deferred financing costs. We and our subsidiary were in compliance with all covenants as of June 30, 2024, and December 31, 2023. Recourse Debt Facilities 3% Green Convertible Senior Notes due June 2029 On May 29, 2024, we issued the 3% Green Notes due June 2029 in an aggregate principal amount of $402.5 million due on June 1, 2029, unless earlier repurchased, redeemed or converted, less an initial purchasers’ discount of $12.1 million and other issuance costs of $0.7 million (together, the “Transaction Costs”), resulting in net proceeds of $389.7 million. The 3% Green Notes due June 2029 were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of May 29, 2024, 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 due June 2029, the Company granted the initial purchasers an option to purchase up to an additional $52.5 million aggregate principal amount of the 3% Green Notes due June 2029 (the “Greenshoe Option”). The 3% Green Notes due June 2029 issued on May 29, 2024, included $52.5 million aggregate principal amount pursuant to the full exercise by the initial purchasers of the Greenshoe Option. The 3% Green Notes due June 2029 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, 2024. We may not redeem the 3% Green Notes due June 2029 prior to June 7, 2027, subject to a partial redemption limitation. We may elect to redeem, at face value, all or any portion of the 3% Green Notes due June 2029 at any time, and from time to time, on or after June 7, 2027 and on or before the twenty-first 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, 2029, the noteholders have the right to convert their 3% Green Notes due June 2029 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 due June 2029 (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 due June 2029 at any time during the immediately following quarter, commencing after the calendar quarter ending on September 30, 2024, subject to the partial redemption limitation. Subject to the Trading Price Condition, the noteholders may convert their 3% Green Notes due June 2029 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 due June 2029, as determined following a request by a holder of the 3% Green Notes due June 2029, 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, 2029, the noteholders may convert their 3% Green Notes due June 2029 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 due June 2029, 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 47.9795 shares of Class A common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $20.84 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 due June 2029 will, in certain circumstances, increase by up to 15.5932 shares of Class A common stock per $1,000 principal amount of notes for a specified period of time. At June 30, 2024, the maximum number of shares into which the 3% Green Notes due June 2029 could have been potentially converted if the conversion features were triggered was 25,588,011 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 due June 2029. The 3% Green Notes due June 2029 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 due June 2029 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 due June 2029 for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the 3% Green Notes due June 2029. The Transaction Costs were recorded as debt issuance costs and represented a reduction to the 3% Green Notes due June 2029 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 due June 2029 for the three months ended June 30, 2024, was $1.3 million and was comprised of contractual interest expense of $1.1 million and amortization of the initial purchasers’ discount and other issuance costs of $0.2 million. We have not recognized any special interest expense related to the 3% Green Notes due June 2029 to date. The amount of unamortized debt issuance costs as of June 30, 2024, was $12.6 million. Although the 3% Green Notes due June 2029 contain embedded conversion features, we account for the 3% Green Notes due June 2029 in its entirety as a liability. As of June 30, 2024, the net carrying value of the 3% Green Notes due June 2029 was classified as a long-term liability in our condensed consolidated balance sheets. 3% Green Convertible Senior Notes due June 2028 and Capped Call Transactions Please refer to Part II, Item 8, Note 7 — Outstanding Loans and Security Agreements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for discussion of our 3% Green Convertible Senior Notes due June 2028 (the “3% Green Notes due June 2028”) and privately negotiated capped call transactions in connection with the pricing of the 3% Green Notes due June 2028.

Half of the original principal balance, $115.0 million of the 2.5% Green Notes, was called and repurchased at 122.6% during the three months ended June 30, 2024. The 22.6% premium of $26.0 million and unpaid accrued interest of $0.8 million related to the repurchased amount were included in the final payment to the noteholders.

Stock Option and Stock Award Activity Stock Options The following table summarizes the stock option activity under our stock plans during the reporting period: Outstanding Options Number of Weighted Remaining Aggregate (in thousands) Balances at December 31, 2023 7,247,624 $ 20.93 3.8 $ 19,446 Granted 1,175,348 9.66 Exercised (118,394) 5.94 Expired (579,293) 26.55 Balances at June 30, 2024 7,725,285 19.01 4.4 16,183 Vested and expected to vest at June 30, 2024 7,384,089 19.46 4.1 15,184 Exercisable at June 30, 2024 6,569,937 $ 20.66 3.4 $ 13,023 During the three and six months ended June 30, 2024, we recognized $1.0 million and $1.2 million of stock-based compensation costs for stock options, respectively. During the three and six months ended June 30, 2023, we recognized $0.1 million and $0.2 million of stock-based compensation costs for stock options, respectively. During the three and six months ended June 30, 2024, we granted 175,348 and 1,175,348 stock options, respectively, including 955,000 stock options granted in the first quarter of fiscal year 2024 to certain executives to purchase shares of common stock that contain certain performance-based vesting criteria related to corporate milestones (the “performance-based stock options”). The performance-based stock options were granted “at-the-money” and have a term of 10 years. The performance-based stock options vest based over a four-year or a three-year requisite service period. We did not grant stock options in the three and six months ended June 30, 2023. The fair value of each performance-based stock option is estimated on the date of grant using the Black-Scholes valuation model. Recognition of stock-based compensation expense associated with these performance-based stock options commences when the performance condition is considered probable of achievement, using management’s best estimates, which consider the inherent risk and uncertainty regarding the future outcomes of the milestones. Forfeitures of the performance-based stock options are recognized as they occur. We used the following weighted-average assumptions in applying the Black-Scholes valuation model for determination of the stock options valuation: Risk-free interest rate 4.1% - 4.4% Expected term (years) 6 Expected dividend yield — Expected volatility 96.0% - 97.1% During the three and six months ended June 30, 2024, the intrinsic value of stock options exercised was $0.2 million and $0.7 million, respectively. During the three and six months ended June 30, 2023, the intrinsic value of stock options exercised was $0.7 million and $1.5 million, respectively. As of June 30, 2024, and December 31, 2023, we had unrecognized compensation costs related to unvested stock options of $7.9 million and $0.1 million, respectively. This cost is expected to be recognized over the remaining weighted-average period of 2.8 years and 0.3 years, respectively. Cash received from stock options exercised totaled $0.2 million and $0.7 million for the three and six months ended June 30, 2024, respectively. Cash received from stock options exercised totaled $0.7 million and $1.5 million for the three and six months ended June 30, 2023, respectively.

The PSUs have vesting schedules that range from one three The PSUs and performance-based stock options will vest based on a combination of time and achievement against performance metrics targets assuming continued employment and service through each vesting date. Stock-based compensation costs associated with the 2024 Executive Awards are recognized over the service period as we evaluate the probability of the achievement of the performance conditions. As of June 30, 2024, the unamortized compensation expense for the RSUs, the PSUs, the time-based and the performance-based stock options per the 2024 Executive Awards was $16.1 million.

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 the restructuring plan (the “Restructuring Plan”) intended to realign our operational focus to support our multi-year growth, scale the business, and improve our cost structure and operating margins. Please refer to Part II, Item 8, Note 12 — Restructuring in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for details. For the six months ended June 30, 2024, impact from restructuring on our condensed consolidated statements of operations was not material. We expect to incur $4.2 million in restructuring costs in subsequent quarters, out of which we expect $3.5 million will relate to relocation costs and $0.7 million will relate to other restructuring costs. 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 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 made against the accrual for the six months ended June 30, 2024 (in thousands): Six Months Ended June 30, 2024 Facility Closure Severance Other Total Balance at December 31, 2023 $ 2,577 $ 464 $ 752 $ 3,793 Restructuring accrual (release) (69) (385) 189 (265) Payments (2,466) (79) (578) (3,123) Balance at June 30, 2024 $ 42 $ — $ 363 $ 405 At June 30, 2024 and December 31, 2023, facility closure costs, severance, and other restructuring costs were included in accrued expenses and other current liabilities in our condensed consolidated balance sheets.

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 are not cancellable. As of December 31, 2023, we had no material open purchase orders with our component suppliers and third-party manufacturers that are expected to be realized within more than a 12-month period and are not cancellable. Performance Guarantees — We guarantee the performance of the 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 $1.8 million and $16.9 million for the three and six months ended June 30, 2024, respectively, for such performance guarantees. For the three and six months ended June 30, 2023, we paid $4.1 million and $19.9 million, respectively, for such performance guarantees. Letters of Credit — In 2019, pursuant to the PPA II upgrade of the 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 June 30, 2024, and December 31, 2023, the balance of this cash-collateralized letter of credit was $20.5 million and $40.4 million, respectively. 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. As of June 30, 2024, and December 31, 2023, the balances of the cash-collateralized letters of credit issued to our customers and other counterparties in the U.S. and international locations were $27.9 million and $32.6 million, respectively. Pledged Funds — In 2019, pursuant to the PPA IIIb upgrade of the 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 June 30, 2024, and December 31, 2023, the balance of the restricted cash fund was $7.7 million and $7.6 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. Investment Tax Credits — Our Energy Servers are eligible for federal Income Tax Credits (the “ITC”) 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 matter 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 consolidated financial condition, 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. On June 4, 2024, the Superior Court issued an order granting the Plaintiffs’ request for the dismissal of the lawsuit with prejudice. 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 $3.0 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 court issued a preliminary approval of the settlement on October 31, 2023. Notice of the settlement together with requested Plaintiff attorney fees was sent to the defined class of Bloom stockholders and on May 2, 2024, the final settlement was approved by the court. On May 9, 2024, in light of the stipulated settlement, the court issued an order dismissing the lawsuit with prejudice. 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. 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 of Santa Clara 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 decision of the Eastern District of Texas. A hearing by the arbitrator in WIPO on arbitrability took place on June 27, 2023. On October 2, 2023, the arbitrator in the WIPO proceeding issued a ruling concluding that all the parties’ claims were arbitrable. On November 18, 2023, the arbitrator bifurcated the arbitration into a first phase that will focus on Bloom’s claims directed to improper inventorship of the Patents-in-Suit and Bloom’s defective product claims. Briefing on the first phase will take place throughout 2024 with a potential evidentiary hearing to be scheduled in 2025. We are unable to predict the ultimate outcome of the arbitration at this time.
