Bloom Energy Corporation
Notes to Unaudited Condensed Consolidated Financial Statements
The unaudited condensed consolidated financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented.
The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Website references throughout this document are provided for convenience only, and the content on the referenced websites is not incorporated by reference into this report.

1. 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, section Liquidity and Basis of Presentation, sub-section Nature of Business in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
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 $1,126.7 million and $4.1 million of total outstanding recourse and non-recourse debt, respectively, as of March 31, 2025, $114.6 million and $1,016.2 million of which was classified as short-term debt and long-term debt, respectively. As of December 31, 2024, we had $1,124.7 million and $4.1 million of total outstanding recourse and non-recourse debt, respectively, $114.4 million and $1,014.4 million of which was classified as short-term debt and long-term debt, respectively.
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 products, 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 on favorable terms or at all 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 cash and cash equivalents and cash flow to be generated by our operations is expected to be sufficient to meet our anticipated cash flow needs for at least the next 12 months from the date of the 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, section Inflation Reduction Act of 2022 in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
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”), and as permitted by those rules, including all disclosures required by generally accepted accounting principles as applied in the U.S. (“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, section Principles of Consolidation in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
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, section Use of Estimates in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Concentration of Risk
Geographic Risk — The majority of our revenue for the three months ended March 31, 2025, is attributable to operations in the U.S., and for the three months ended March 31, 2024 — to operations with customers in the Republic of Korea, Japan, India, and Taiwan (collectively referred to as the “Asia Pacific region”). The majority of our long-lived assets are attributable to operations in the U.S. for all periods presented. For the three months ended March 31, 2025, and 2024, total revenue in the U.S. was 56% and 40%, respectively, of our total revenue.
Credit Risk — At March 31, 2025, three customers, the second of which is our related party (see Note 10 — Related Party Transactions), accounted for approximately 32%, 27%, and 14% of accounts receivable. At December 31, 2024, three customers, the first of which is our related party (see Note 10 — Related Party Transactions), accounted for approximately 28%, 28%, and 20% of accounts receivable. To date, we have not experienced any material credit losses from these customers.
Customer Risk — During the three months ended March 31, 2025, revenue from two customers, accounted for approximately 37% and 29% of our total revenue. During the three months ended March 31, 2024, two customers, the first of which is our related party (see Note 10 — Related Party Transactions), represented approximately 52% and 15% of our total revenue.

2. Summary of Significant Accounting Policies
Refer to the accounting policies described in Part II, Item 8, Note 2 — Summary of Significant Accounting Policies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Accounting Guidance Not Yet Adopted
Refer to the accounting guidance not yet adopted described in Part II, Item 8, Note 2 — Summary of Significant Accounting Policies, section Accounting Guidance Not Yet Adopted in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Based on the Company’s continued evaluation, we do not expect a material impact from new accounting guidance not yet adopted to our condensed consolidated financial statements.
Recent Accounting Pronouncements
There have been no significant changes in our reported financial position or results of operations and cash flows resulting from the adoption of new accounting pronouncements.

11. Commitments and Contingencies
Commitments
Purchase Commitments with Suppliers and Contract Manufacturers — As of March 31, 2025, and December 31, 2024, 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. For additional information on purchase commitments with suppliers and contract manufacturers, see Part II, Item 8, Note 13 — Commitments and Contingencies, section Commitments in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Performance Guarantees — We paid $11.6 million and $15.1 million for the three months ended March 31, 2025, and 2024, respectively, for guarantees that we provide customers on the output performance of our Energy Server systems. For additional information on performance guarantees, see Part II, Item 8, Note 13 — Commitments and Contingencies, section Commitments in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Letters of Credit — In 2019, pursuant to the PPA II repowering of the Energy Server systems, 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 March 31, 2025, and December 31, 2024, the balance of this cash-collateralized letter of credit was $5.4 million and $9.5 million, respectively.
In December 2024, we issued a $100.0 million letter of credit in favor of one of our major customers to guarantee the performance in accordance with the limited indemnity and cooperation agreement dated November 14, 2024, related to the supply of 100 MW of Energy Server systems. This letter of credit was released in the quarter ended March 31, 2025.
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 March 31, 2025, and December 31, 2024, the balances of the cash-collateralized letters of credit issued to our customers and other counterparties in the U.S. and international locations other than PPA II were $23.8 million and $131.2 million, respectively.
Pledged Funds — In 2019, pursuant to the PPA IIIb repowering of the Energy Server systems, 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. These funds will be released to us by the end of 2026 as long as the Energy Server systems continue to perform in compliance with our warranty obligations. As of March 31, 2025, and December 31, 2024, the balance of the restricted cash fund was $7.4 million and $7.4 million, respectively.
Contingencies
Indemnification Agreements — See Part II, Item 8, Note 13 — Commitments and Contingencies, section Contingencies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations with customers and certain other business partners. However, we may record charges in the future as a result of these indemnification obligations.
Investment Tax Credits — See Part II, Item 8, Note 13 — Commitments and Contingencies, section Contingencies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
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 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 took place throughout 2024 with an evidentiary hearing scheduled for July 21, 2025. We are unable to predict the ultimate outcome of the arbitration at this time.

12. Segment Information
ASC 280, Segment Reporting, (“ASC 280”) establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Based on the criteria established by ASC 280, our chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer. The CODM reviews consolidated results when making decisions about allocating resources and assessing the performance of the Company as a whole and hence, we have only one reportable segment. We do not distinguish between markets or segments for the purpose of internal reporting.
For discussion of significant segment expenses, other segment items and the Company’s primary measure of segment profitability, refer to Part II, Item 8, Note 14 — Segment Information in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
For information on the Company’s geographic risk, please refer to Note 1 — Nature of Business, Liquidity and Basis of Presentation, section Concentration of Risk.

13. Income Taxes
For the three months ended March 31, 2025 and 2024, we recorded an income tax provision (benefit) of $0.4 million and $(0.5) million on pre-tax losses of $23.0 million and $57.0 million for effective tax rates of (1.9)% and 0.9%, respectively.
The effective tax rate for the three months ended March 31, 2025, and 2024, is lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets.
For additional information on income taxes, refer to Part II, Item 8, Note 15 — Income Taxes in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Overview
Description of Bloom Energy
Our mission is to make clean, reliable energy affordable for everyone in the world. We developed the first large-scale, commercially viable solid oxide fuel cell based power generation platform that empowers businesses, essential services, critical infrastructure and communities to responsibly take charge of their energy. For additional information, refer to Part I, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, section Overview, sub-section Description of Bloom Energy in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Energy Market Conditions
The global energy transition towards a net-zero environment has created new challenges and opportunities for utilities, suppliers of energy solutions, and customers. Shifts and uncertainty in market and regulatory dynamics and corporate and governmental policies are currently impacting the selling process and impacting sales cycles and timelines for our products. Increasing electricity rates, decreasing energy security and reliability, and delays in the development of transmission
28

infrastructure and grid interconnection as well as other time-to-power challenges have led to increased customer interest in our power solutions. At the same time, ongoing natural gas supply and pricing concerns due to geopolitical stresses, as well as customers’ interest in meeting sustainability targets, have led to increased caution from potential customers in their buying decision for energy solutions. Increasing demand for power has forced utilities, states and countries to revisit less clean sources of baseload and intermediate power, which our technology is designed to replace. This supply and demand mismatch globally has threatened energy security, reliability, and availability.
Bloom enables customers to address these energy market challenges by offering fuel flexible solutions designed to provide cost predictable, resilient, and reliable energy in a timely fashion. As customers and utilities navigate the energy transition and evolving landscape, the ability of our power solutions to fit their economic, regulatory, and policy needs depends on a number of factors, including natural gas availability and pricing, electrical interconnection needs and availability, redundant back up power requirements, cost requirements, and sustainability profiles. These factors may influence a customer’s decision to pursue an alternative power solution like ours — even in cases where utility interconnection timeliness span years – because the total cost to interconnect, including the build-out of energy transmission infrastructure, often remains unknown until all interconnection studies are completed.
Policy proposals that have emerged in 2025 may also affect customer demand for power solutions. For example, changes to permitting rules could accelerate domestic fossil fuel infrastructure production, while proposals to limit environmental reviews under the National Environmental Policy Act and other statutes could incentivize investment in, and reduce the cost of, fossil fuels, including natural gas. At the same time, proposals to halt new permits for wind projects, particularly offshore wind, could slow renewable energy adoption and decrease the projected available supply of renewable energy. Bloom stands ready to meet these new opportunities with our low-emission Energy Server systems.
Many data center customers and other large power users have signed exclusivity arrangements with their utilities, and this often creates a more complicated dynamic for them to move to an on-site solution. Rising natural gas costs in some regions, increases in gas distribution rates, limited availability of supply, and disruptions in global gas markets have increased the cost of our power solutions for customers and, in certain cases where fuel is unavailable, have resulted in a complete inability to operate the systems. In the U.S., the lack of, or slow development in, pipeline infrastructure has, in the past, impacted the timing of customers being able to take advantage of our power solution opportunities. In certain jurisdictions in the U.S. and Europe, natural gas bans have prevented the use of our power solutions unless alternative fuels are available.
In addition, many of our potential data center and industrial customers are pursuing greenfield opportunities where the development cycle is long and laden with permitting requirements, and the uncertainty of these factors is leading to a more complex customer decision-making process and longer sales cycles. Data center greenfield projects require significant investments in real estate, facility costs, and technology, among other elements, in addition to the investment in our power solutions, and the timing and sequencing of those investments is largely outside of our control.
Key Macro Trends
Increases in Demand for Power, Driven by Data Centers and Artificial Intelligence (AI)
Demand for power has continued to significantly outpace available grid-based generation supply, with the need for additional power becoming increasingly acute in recent periods. Key factors driving the increasing demand include the transition towards the electrification of transportation and buildings, the rapid adoption of AI that has led to the expansion of existing data centers and plans for new greenfield data centers, and Federal incentives for domestic manufacturing, including semiconductor and battery production. These factors, along with economic growth, have placed significant stress on grid supply and have led companies to consider on-site distributed power, including Bloom Energy Server systems, to meet their power needs.
Time to Power Increases as Power Demand/Supply Mismatch Grows
The increase in power demand, has, in part, elevated the importance of time to power. According to a study published in April 2024 by the Lawrence Berkeley National Laboratory, the time from initiating a request for interconnection to the grid to the start of commercial operations has more than doubled from less than two years during the period from 2000-2007, to more than four years from 2018-2023. Bloom Energy Server systems can be configured as on-site fully-islanded, microgrid solutions that are not interconnected to the grid, which often can provide a customer power in months instead of years. Many utilities have informed data center and manufacturing customers that they cannot interconnect for a period of years because the utility has no power available to serve a customer’s needs, thus making the Bloom Energy Server system an attractive alternative. In addition, our fully-islanded microgrid solutions can provide power on-site, without the need for costly transmission and distribution system upgrades that often are required before a customer can interconnect to the electrical grid. We are seeing
29

greater interest in fully-islanded, microgrid solutions among data center customers because of these interconnection-related delays. If a customer desires back up power or a “grid parallel” solution in combination with the Bloom Energy Server system, required interconnection studies and lengthy interconnection queues may remain, eroding the time to power value proposition.
Co-locating Large Loads with Distributed Generation Configured as Islanded Microgrids are Gaining in Traction as Energy Solutions to Bypass Long Interconnection Queues and Transmission Upgrades
Our islanded microgrid solution allow data center and other customers the ability to skip the interconnection queue and start construction. A key to this solution is that our Be FlexibleTM load following capability allows us to follow a customer’s variable loads without the need to import power from the transmission grid. We believe avoiding lengthy interconnection queues is key to unlocking time to power for our customers. Our islanded microgrid solution also creates ratepayer savings by reducing congestion charges resulting from constraints on the transmission grid and avoiding the need for network transmission investments and upgrades that may be allocated to all ratepayers. In addition to serving a single customer as a distributed generation microgrid solution, our technology can also be used by utilities as an energy transmission asset, helping them serve customers while avoiding the costs of building new transmission and distribution infrastructure.
Utilities are Turning to Distributed Energy Solutions to Decrease their Customers’ Time to Power
Our utility customers are recognizing the challenge of keeping pace with the growing demand for power. Aging infrastructure, coupled with transmission and distribution bottlenecks, are making it more difficult for utilities to integrate additional sources of energy to add capacity. Building new transmission and distribution infrastructure is expensive, takes many years, and would likely cause utility rates to increase. As demand for power continues to grow, utility companies are struggling to meet the soaring demand of data centers, while customers’ time to power becomes increasingly important. Utility companies are exploring alternative means of producing and supplying energy to their end customers, including our Energy Server systems. In 2024, we entered into multiple agreements with utilities, including a landmark 1 GW supply agreement with a customer that included a 100 MW order in 2024. We expect more utility customers in the future to supplement their power generation with the Bloom Energy Server system. As we work to reduce our product costs, and with utility rates expected to rise due to significant infrastructure investments projected over the next five years to meet rapid demand growth, we expect our energy solutions to become more cost-competitive across more countries, communities, and industries worldwide.
Fuel Flexible Solutions Address Reliability Concerns as well as Near- and Long-term Sustainability Considerations
The impacts of climate change, including more severe and unpredictable weather events, have placed additional strain on aging utility grids and contributed to periods of power outages for those reliant on them. In addition, the recognition of the threat of climate change has led companies and governments to set ambitious emissions goals to reduce the release of carbon dioxide to the atmosphere. Large increases in demand for power are expected to challenge prevailing carbon reduction trajectories when large power users turn to conventional solutions to meet their needs. The Energy Server system is able to provide highly available power to displace dirtier and less efficient conventional combustion solutions like turbines and engines. Deeper decarbonization potential is enabled through fuel flexibility, combined heat and power (“CHP”) offerings and carbon capture utilization and storage (“CCUS”) capability. In addition to natural gas, our non-combustion power solutions are designed to run on biofuels or hydrogen, emit near-zero criteria pollutants, and use no water during steady state operation.
Other Factors Affecting our Performance
Shifting Regulatory Environment
In the U.S., the ITC for fuel cells operating on non-zero-carbon fuels expired at the end of fiscal 2024. Although the Company and its customers utilized compliant safe harbor mechanisms to secure deployment of a certain dollar amount of Energy Server systems through 2028, the failure to extend the ITC for such fuel cells could materially impact U.S. bookings, revenue and gross margins in 2025 and beyond.
The IRA established a new clean electricity production credit and a clean electricity investment credit. Although the U.S. Treasury Department developed rules to implement credits and incentives for clean energy resources under President Biden’s administration, there is considerable uncertainty around whether, or the conditions under which such credits will be available for transactions involving our solutions in the future, including as a result of actions taken by President Trump’s administration. For information on the IRA and its impact on our business, see Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, section Inflation Reduction Act of 2022 in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
In addition, delays in adoption of Renewable Fuel Standard regulations in the U.S. for the use of biogas to generate electricity for electric vehicles, along with limited governmental focus on the utilization of biogas outside of use by methane-
30

fueled vehicles, have created uncertainty around the broader availability of biogas for industrial uses, including our power solutions. Furthermore, in most jurisdictions, air permits and various land use permits are required for installation of our solutions above certain megawatt thresholds. The time required to obtain these permits has generally increased, while the certainty of approval has decreased, and when issued, the cost of meeting compliance requirements can be cost prohibitive. We have experienced a reluctance in certain states to issue permits for gas generation equipment. Even if issued, states may require a blend of costly renewable fuels or other measures to advance climate goals.
In Ireland, a major data center market, a directive from the Minister for the Department of the Environment, Climate and Communications under the previous administration to restrict grid connections for data centers and other large power users, along with a halt in high-pressure gas installations, has delayed our sales activities. In 2023, the South Korean government moved to a new, government-run bidding process for fuel cell purchases, which has adversely impacted and may continue to impact demand for our power solutions.
Working with Utilities
The imbalance between power demand and supply has contributed to utilities seeking alternative sources of power to supply to their end customers. Utilities have been unable to meet this demand through the deployment of renewable sources of energy such as solar and wind power. Bloom Energy Server systems can be installed at the utility’s point of distribution or directly on the customer’s site. The energy produced by our systems can be utilized by utilities to provide power to a specific customer or customers or may be used by customers generally. As demand for power continues to grow, and time to power becomes increasingly important, utilities are exploring alternative means of producing and supplying energy to their end customers, including using our Energy Server systems. In 2024, we entered into multiple agreements with utilities, including a landmark 1 GW supply agreement with a customer that included a 100 MW order in 2024. We expect more utility customers in the future to supplement their power generation with the Bloom Energy Server system. Increasing the supply of available power can allow utilities to encourage end customers to remain in their current locations rather than relocating to areas where power is more available. In addition, co-locating our Energy Server systems on-site with large loads, can enable a utility to provide power to a large energy user without impacting its rate base and providing the onsite power as an islanded microgrid can avoid interconnection studies and wait times.
Hydrogen Market Developments
The interest, investment, and stimulation of clean hydrogen in the U.S., Europe and in many other regions across the globe have not yet had significant impacts on the supply of hydrogen. To date, while the number of proposed hydrogen production projects has grown rapidly, only a small fraction has reached the final investment decision stage, and an even smaller fraction has been deployed. In addition, the infrastructure needed to transport hydrogen, whether through pipelines or maritime or land-based tankers, is currently only sufficient for existing uses, and has not begun to be significantly extended for anticipated future uses, with hydrogen blending and other approaches remaining at pilot stages. It remains unclear whether regulators in some jurisdictions will allow hydrogen to be introduced into gas distribution systems, which could limit our customers’ ability to transport hydrogen from the point of production to the point of consumption. Additionally, while U.S. Treasury Department rules regarding the use of market-based renewable energy have been clarified, hurdles remain that could hinder the large-scale development of hydrogen projects. Uncertainty also exists as potential changes may be pursued by the new U.S. federal administration and Congress.
Lengthening Sales Cycles
Many of the factors discussed above have lengthened the selling cycles for our products and we have experienced delays in our anticipated bookings as a result. Our revenue, margins, and cash flow in any given year depend on bookings from prior years as well as current-year bookings. Historically, the majority of our bookings have occurred in the second half of the year, with a significant portion in the fourth quarter, and we expect this trend to continue in 2025. However, if a substantial portion of our anticipated bookings is delayed beyond our expectations, our revenue, margins, and cash flow for the relevant period could be materially adversely impacted.
Supply Chain Constraints
We continue to see effects from global supply chain tightness due to the current inflationary environment, war in Ukraine, and trade tensions between the U.S. and China. We are not aware of, and do not expect any significant direct impact on our business or supply chain from the armed conflict in Israel and neighboring areas. While we have not experienced any significant component shortages to date, we are facing pressures from inflation. These dynamics could worsen as a result of continued geopolitical instability or escalation of current military conflicts or trade tensions. The new U.S. federal administration has implemented new tariffs on all trade partners. Our supply chain is not dependent on China, but significant tariffs on imports from other countries where we do source materials could impact our costs. At the tariffs present levels of
31

10%, we expect an impact on gross margin of approximately one percent for the fiscal year 2025. Changes in U.S. or international trade policies, including retaliatory measures, along with continued uncertainty surrounding such policies, could lead to further weakened business conditions for our industry, which may adversely impact our operations, including through increased supply chain challenges and project delays. The ultimate impact of tariffs may be of a different nature and/or of a larger magnitude than we anticipate.
We are also reliant on third party providers of storage equipment, infrastructure equipment and pipelines, and other materials and technologies that work with our products to provide an energy solution for customers. In the event we are unable to mitigate the impacts of delays and rising prices for raw materials and components, including those caused by new tariffs, it could delay the manufacturing and installation, increase the costs of our products and the overall project, and adversely affect our cash flow and results of operations, including revenue and gross margin.
Installations and Maintenance of our Products
In previous years, our installation projects experienced delays related to, among other factors, permitting, utility coordination, and access to customer facilities. We have not experienced any delays in 2025 in either our installation or maintenance activities. If we are delayed in or unable to perform maintenance, our previously installed products would likely experience adverse performance impacts, including reduced output and/or efficiency, which could result in warranty and/or guaranty claims by our customers. If we experience a significant increase of product failure in the future, our service expense may increase and we may fail to achieve the performance commitments to our customers, which could result in warranty and/or guaranty claims. Additionally, product failure and service costs may increase as we initially deploy new applications for our Energy Server system, including Be FlexibleTM load following, CCUS, and CHP.
Financing Constraints
As we grow our business globally and increase the size and number of customer orders, we will need to secure new customer financing options, the amount of financing available as well as the number of financing partners. As we offer an innovative new technology solution, obtaining new financing partners and available funds for customer financings often involves a rigorous and timely due diligence process on our technology, manufacturing and service capabilities. If we are unable to obtain adequate financing for our customers who prefer third-party financing over purchasing the Energy Server system directly, our revenue could be delayed or impacted. In addition, our ability to arrange financing for our products depends partly on the creditworthiness of our customers, and any deterioration in their credit ratings could impact that financing. When interest rates rise, the cost of financing for our customers also increases, and financing our installations may require a higher rate of return, which can place pressure on our margins.
Manufacturing and Labor Market Constraints
As recently as 2022, we experienced impacts from labor shortages and challenges in hiring for our manufacturing facilities. While these constraints have since abated, and we reduced headcount as part of the Restructuring Plan adopted in September 2023, we may still experience difficulties with hiring and retention and may face additional labor shortages in the future. For details on the Restructuring Plan refer to Part II, Item 8, Note 12 — Restructuring in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. In addition, the current inflationary environment has led to rising wages and labor costs as well as increased competition for labor.
Strategic Investment
For information on the strategic investment with SK ecoplant, 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, 2024.
Sustainability
In April 2025, we released our 2025 Impact Report, previously referred to as our Sustainability Report, Transforming Energy for the Digital Age (the “Impact Report”), using generally accepted sustainability frameworks and standards, including alignment with Sustainability Accounting Standards Board standards and the Task Force on Climate-related Financial Disclosures recommendations. In addition, the Impact Report also utilized certain Global Reporting Initiative Standards and was mapped against the United Nations Sustainable Development Goals. We plan to issue an impact report on an annual basis.
The Impact Report can be found on our website at https://www.bloomenergy.com/sustainibility. Website references throughout this document are provided for convenience only, and the content on the referenced websites is not incorporated by reference into this report.

Inflation Reduction Act of 2022
For information on the IRA, which was signed into law on August 16, 2022, and its impact on our business, see Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, section Inflation Reduction Act of 2022 in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Other than the loss of the ITC for fuel cells operating on non-zero-carbon fuels expired at the end of fiscal 2024, which occurred under President Biden’s administration, we have not experienced any impact from actions relating to the IRA taken by President Trump administration.
Liquidity and Capital Resources
As of March 31, 2025, and December 31, 2024, we had unrestricted cash and cash equivalents of $794.8 million and $802.9 million, respectively. Our cash and cash equivalents consist of highly liquid investments with maturities of three months or less, including money market funds of $759.5 million and $749.4 million as of March 31, 2025, and December 31, 2024, respectively. We seek to maintain these balances with high-credit-quality counterparties, regularly monitor our credit exposure to any single issuer, and diversify our investments to minimize risk.
As of March 31, 2025, we had $1,126.7 million of recourse debt, $4.1 million of non-recourse debt, and $9.4 million of other long-term liabilities. As of March 31, 2025, $114.6 million and $1,016.2 million of our debt were classified as short-term and long-term, respectively. As of December 31, 2024, we had $1,124.7 million of recourse debt, $4.1 million of non-recourse debt, and $9.2 million of other long-term liabilities. As of December 31, 2024, $114.4 million and $1,014.4 million of our debt were classified as short-term and long-term, respectively. For a complete description of our outstanding debt, please see Part II, Item 8, Note 17 — Outstanding Loans and Security Agreements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
The combination of our cash and cash equivalents and cash flow expected to be generated by our operations is expected to be sufficient to meet our anticipated cash flow needs for at least the next 12 months. If these sources of cash are insufficient or not received in a timely manner to meet our near-term or future liquidity needs, we may require additional equity or debt financing to fund our operations, manufacturing capacity, product development, and market expansion initiatives, as well as to respond to competitive pressures or strategic opportunities. We may, from time to time, engage in a variety of financing transactions for such purposes, including factoring our accounts receivable. During the three months ended March 31, 2024, we factored $80.7 million of accounts receivable, and there were no factoring arrangements during the three months ended March 31, 2025. However, we may not be able to secure timely additional financing on favorable terms, or at all. The terms of any additional financing may limit on our financial and operational flexibility. Although we currently do not have any floating-rate notes on our balance sheet, our overall cost of capital may increase if interest rates rise and we refinance our fixed-rate convertible notes. If we raise additional funds through the issuance of equity or equity-linked securities, our existing stockholders could experience dilution in their ownership percentage, and any new securities may have rights, preferences, and privileges senior to those of our common stock.
Our future capital requirements depend on a variety of factors, including our rate of revenue growth; the timing and extent of spending on research and development and other business initiatives; the pace and volume of system builds; the need for additional working capital; the expansion of our sales and marketing activities in both domestic and international markets; market acceptance of our products; our ability to secure financing for customer use of our products; the timing of installations and related inventory build in anticipation of future sales; 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 results of operations, including our revenues and cash flows.

Operating Activities
Our operating activities consisted of net loss adjusted for certain non-cash items plus changes in our operating assets and liabilities or working capital. Net cash used in operating activities for the three months ended March 31, 2025, related primarily to the changes in our working capital of $137.9 million predominantly due to (1) a decrease in deferred revenue and customer deposits by $74.9 million, driven by timing of acceptances, (2) an increase in inventory levels by $65.6 million to support future demand, (3) an increase in deferred cost of revenue of $7.5 million, and (4) an increase in prepaid expenses and other current assets of $5.1 million, partially offset by the timing of payments to vendors.
Net cash used in operating activities during the three months ended March 31, 2025, was $110.7 million, an improvement of $36.6 million compared to the prior year period. The change in cash used in operating activities during the three months ended March 31, 2025, as compared to the prior year period, was primarily driven by an increase of $40.6 million and $8.6 million attributable to inventories and prepaid expenses and other current assets, respectively, a $57.3 million decrease attributable to deferred revenue and customer deposits, partially offset by an increase of $86.0 million attributable to accounts payable.
Investing Activities
Our investing activities have consisted of capital expenditures, including investments to increase our production capacity. Cash used in investing activities during the three months ended March 31, 2025, was $14.2 million, an improvement of $7.2 million, as compared to the prior year period. The improvement was primarily due to the decrease in expenditures on tenant improvements for a leased engineering and manufacturing facility in Fremont, California, which opened in July 2022. We expect to continue to make capital investments over the next few quarters to expand production capacity at our manufacturing facility in Fremont, California, which includes the purchase of new equipment and other tenant improvements. We intend to fund these capital expenditures from cash on hand as well as cash flow expected to be generated from operations. We may also evaluate and arrange equipment lease financing to fund this capital expenditures.
Financing Activities
Our financing activities consist of proceeds from and repayments of financing obligations, contributions from noncontrolling interests, proceeds from issuance of our common stock, and other cash flows from financing activities. Net cash provided by financing activities during the three months ended March 31, 2025, was $5.1 million, a decrease of $2.0 million, as compared to the prior year period, predominantly due to (1) a decrease in contributions from noncontrolling interest by $4.0 million, and (2) a decrease in proceeds from financing obligations by $1.3 million, partially offset by (1) a decrease in repayment of financing obligations by $2.3 million, and (2) an increase in proceeds from issuance of common stock by $0.8 million.
Net cash provided by financing activities for the three months ended March 31, 2025, consisted of (1) the proceeds from issuance of common stock of $7.7 million, (2) the repayment of financing obligations of $2.7 million, and (3) other cash flows from financing activities of $0.2 million.
We believe we have sufficient capital to operate our business over the next 12 months. Our working capital was strengthened with the supplemented liquidity through issuing the 3% Green Notes due June 2029 and the 3% Green Notes due June 2028 in the second quarter of 2024 and 2023, respectively, as well as financing activities with SK ecoplant in the first quarter of 2023.

Total operating expenses increased by $20.7 million in the three months ended March 31, 2025, as compared to the prior year period. This increase was primarily attributable to (1) an increase in employee compensation and benefits of $16.6 million, predominantly due to an increase in stock-based compensation and bonus expenses, (2) an increase in consulting, advisory and other professional services costs of $2.4 million, (3) an increase in computer equipment maintenance expenses of $1.6 million, (4) an increase in consumable laboratory supplies and other laboratory related costs of $0.8 million, and (5) an increase in depreciation expenses of $0.8 million. The overall increase was partially offset by a decrease in office and other operating expenses of $1.5 million, primarily related to corporate insurance costs and factoring and financing fees.
Research and Development
Research and development expenses increased by $5.1 million in the three months ended March 31, 2025, as compared to the prior year period. This overall increase was primarily driven by (1) an increase in employee compensation and benefits of $4.0 million, predominantly due to an increase in stock-based compensation and bonus expenses, (2) an increase in consumable laboratory supplies and other laboratory-related costs of $0.8 million, and (3) an increase in consulting, advisory and other professional services costs of $0.6 million. The increase was partially offset by a decrease in other research and development expenses of $1.0 million.
Sales and Marketing
Sales and marketing expenses increased by $8.7 million in the three months ended March 31, 2025, as compared to the prior year period. The increase was primarily driven by (1) an increase in employee compensation and benefits of $6.0 million, predominantly due to an increase in stock-based compensation and bonus expenses, and (2) an increase in consulting, advisory and other professional services costs of $1.9 million.
General and Administrative
General and administrative expenses increased by $6.9 million in the three months ended March 31, 2025, as compared to the prior year period. This increase was primarily driven by (1) an increase in employee compensation and benefits of $6.6 million, predominantly due to stock-based compensation expenses, principally related to new awards for our Chief Executive Officer (the “CEO”) granted on December 18, 2024, partially offset by a decrease in bonus expenses, (2) an increase in computer equipment maintenance expenses of $1.1 million, and (3) an increase in depreciation expenses of $0.7 million. The overall increase was partially offset by a decrease in office and other general and administrative expenses of $1.9 million, primarily related to corporate insurance costs and factoring and financing fees.

Total stock-based compensation for the three months ended March 31, 2025, increased by $13.3 million, as compared to the prior year period, and the increase was predominantly related to an increase of stock-based compensation related to PSUs and RSUs of $10.9 million, an increase in stock-based compensation costs related to the 2018 ESPP of $3.5 million, and an increase of stock-based compensation costs related to stock options of $1.2 million, partially offset by a $2.3 million consisting of capitalized stock-based compensation expenses and stock-based compensation cash component. The increase was primarily driven by (1) new awards for our CEO granted on December 18, 2024, (2) increase in a number of granted RSUs provided to all employees of the Company starting fiscal year 2025, (3) an increase in Bloom’s share price, and (4) an increase in contributions to 2018 ESPP.

Total$(3,913)$(8,027)$4,114 
Interest Income
Interest income is derived from investment earnings on our cash balances, primarily from money market funds. The increase in interest income of $1.0 million for the three months ended March 31, 2025, as compared to the prior year period, was primarily due to an increase in average cash balance in our money market funds for the respective period.
Interest Expense
Interest expense is primarily due to our debt held by third parties and interest expense related to managed services agreements.
A decrease in interest expense for the three months ended March 31, 2025, was not material, and was primarily due to (1) a decrease in interest expense of $2.8 million related to managed services agreements, and (2) the partial repurchase of the 2.5% Green Notes on May 29, 2024, contributing a decrease in interest expense of $1.0 million, partially offset by an increase in interest expense of $3.7 million related to the 3% Green Notes due June 2029, issued on May 29, 2024.
Other Income (Expense), Net
Other income (expense), net is primarily derived from foreign currency transactions and other income related to managed services transactions. Other income (expense), net for the three months ended March 31, 2025, improved by $3.2 million, as compared to the prior year period, primarily as a result of a $2.5 million other income related to managed services transactions, and a decrease in loss from foreign currency transactions of $1.0 million.
40

Loss (Gain) on Revaluation of Embedded Derivatives
Loss (gain) on revaluation of embedded derivatives is derived from the change in fair value of our sales contracts of embedded Escalation Protection Plan derivatives valued using historical grid prices and available forecasts of future electricity prices to estimate future electricity prices. Loss (gain) on revaluation of embedded derivatives for the three months ended March 31, 2025, as compared to the prior year period, was immaterial.

Income tax provision (benefit)

Income tax provision (benefit) consists primarily of income taxes in foreign jurisdictions in which we conduct business. We maintain a full valuation allowance for domestic deferred tax assets, including net operating loss and certain tax credit carryforwards. The income tax benefit flipped to the income tax provision for the three months ended March 31, 2025, as compared to the prior year period. The change was primarily due to fluctuations in the effective tax rates on income earned by international entities.

Net income attributable to noncontrolling interest
$400 $981 $(581)(59.2)%
Net income attributable to noncontrolling interests is the result of allocating profits and losses to noncontrolling interests under the hypothetical liquidation at book value (“HLBV”) method. HLBV is a balance sheet-oriented approach for applying the equity method of accounting when there is a complex structure, such as consolidation of a variable interest entity (“VIE”).
Net income attributable to noncontrolling interests for the three months ended March 31, 2025, as compared to the prior year period, decreased by $0.6 million due to a decrease in income allocated to our noncontrolling interest related to Korean JV, our consolidated VIE.
Critical Accounting Policies and Estimates
The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles as applied in the United States (“U.S. GAAP”). The preparation of the condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. Our discussion and analysis of our financial results under Results of Operations above are based on our results of operations, which we have prepared in accordance with U.S. GAAP. In preparing these condensed consolidated financial statements, we make assumptions, judgments and estimates that can affect the reported amounts of assets, liabilities, revenues and expenses, and net income. On an ongoing basis, we base our estimates on historical experience, as appropriate, and on various other assumptions that we believe to be reasonable under the circumstances. Changes in the accounting estimates are representative of estimation uncertainty and are reasonably likely to occur from period to period. Accordingly, actual results could differ significantly from the estimates made by our management. We evaluate our estimates and assumptions on an ongoing basis. To the extent that there are material differences between these estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. We believe that the following critical accounting policies involve a greater degree of judgment and complexity than our other accounting policies. Accordingly, these are the policies we believe are the most critical to understanding and evaluating the consolidated financial condition and results of operations.
41

The accounting policies that most frequently require us to make assumptions, judgments and estimates, and therefore are critical to understanding our results of operations, include:
•Revenue Recognition;
•Valuation of Assets and Liabilities of the SK ecoplant Strategic Investment;
•Modification of Performance-Based Stock Unit Awards;
•Income Taxes; and
•Principles of Consolidation.
Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operation in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 provides a more complete discussion of our critical accounting policies and estimates. During the three months ended March 31, 2025, there were no significant changes to our critical accounting policies and estimates.

ITEM 3 — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
There were no significant changes to our quantitative and qualitative disclosures about market risk during the three months ended March 31, 2025. Please refer to Part II, Item 7A, Quantitative and Qualitative Disclosures about Market Risk included in our Annual Report on Form 10-K for our fiscal year ended December 31, 2024, for a more complete discussion of the market risks we consider.

ITEM 4 — CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our CEO (our Principal Executive Officer) and Chief Financial Officer (our Principal Financial Officer) as appropriate, to allow for timely decisions regarding required disclosure.
Our management, with the participation of our CEO and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of March 31, 2025. Based on such evaluation, our CEO and Chief Financial Officer have concluded that as of March 31, 2025, our disclosure controls and procedures were effective.
Changes in Internal Control over Financial Reporting
During the three months ended March 31, 2025, there were no changes in our internal control over financial reporting, which were identified in connection with management’s evaluation required by paragraphs (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
For further information on inherent limitations on effectiveness of internal controls and management’s report on internal control over financial reporting, see Part II, Item 9A, Controls and Procedures in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

We are, and from time to time we may become, involved in legal proceedings or subject to claims arising in the ordinary course of our business. For a discussion of our legal proceedings, see Part I, Item 1, Note 11 — Commitments and Contingencies. We are not presently a party to any other legal proceedings that in the opinion of our management and if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows.

Nature of Business
For information on the nature of our business, see Part II, Item 8, Note 1 — Nature of Business, section Liquidity and Basis of Presentation, sub-section Nature of Business in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
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 $1,126.7 million and $4.1 million of total outstanding recourse and non-recourse debt, respectively, as of March 31, 2025, $114.6 million and $1,016.2 million of which was classified as short-term debt and long-term debt, respectively. As of December 31, 2024, we had $1,124.7 million and $4.1 million of total outstanding recourse and non-recourse debt, respectively, $114.4 million and $1,014.4 million of which was classified as short-term debt and long-term debt, respectively.
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 products, 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 on favorable terms or at all 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 cash and cash equivalents and cash flow to be generated by our operations is expected to be sufficient to meet our anticipated cash flow needs for at least the next 12 months from the date of the issuance of this Quarterly Report on Form 10-Q.

During the three months ended March 31, 2025, and 2024, we recognized $1.4 million and $0.2 million of stock-based compensation costs for stock options, respectively.
During the three months ended March 31, 2025, and 2024, we granted 100,000 and 1,000,000 stock options, respectively. Of these, 100,000 and 955,000 stock options were granted to non-executive and executive employees, respectively, to purchase shares of common stock, subject to performance-based vesting criteria tied to corporate milestones (the “PSOs”). PSOs have a 10-year term, an exercise price equal to the fair market value of our Class A common stock on the date of grant, and vest over a three- or four-year requisite service period.
We used the following weighted-average assumptions in applying the Black-Scholes valuation model for determination of the stock options valuation:

During the three months ended March 31, 2025, and 2024, the intrinsic value of stock options exercised were $1.2 million and $0.5 million, respectively.
As of March 31, 2025, and December 31, 2024, we had unrecognized compensation costs related to unvested stock options of $6.3 million and $7.2 million, respectively. This cost is expected to be recognized over the remaining weighted-average period of 1.8 years and 2.1 years, respectively. Cash received from stock options exercised totaled $1.2 million and $0.5 million for the three months ended March 31, 2025, and 2024, respectively.

Commitments and Contingencies Commitments and Contingencies
Commitments
Purchase Commitments with Suppliers and Contract Manufacturers — As of March 31, 2025, and December 31, 2024, 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. For additional information on purchase commitments with suppliers and contract manufacturers, see Part II, Item 8, Note 13 — Commitments and Contingencies, section Commitments in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Performance Guarantees — We paid $11.6 million and $15.1 million for the three months ended March 31, 2025, and 2024, respectively, for guarantees that we provide customers on the output performance of our Energy Server systems. For additional information on performance guarantees, see Part II, Item 8, Note 13 — Commitments and Contingencies, section Commitments in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Letters of Credit — In 2019, pursuant to the PPA II repowering of the Energy Server systems, 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 March 31, 2025, and December 31, 2024, the balance of this cash-collateralized letter of credit was $5.4 million and $9.5 million, respectively.
In December 2024, we issued a $100.0 million letter of credit in favor of one of our major customers to guarantee the performance in accordance with the limited indemnity and cooperation agreement dated November 14, 2024, related to the supply of 100 MW of Energy Server systems. This letter of credit was released in the quarter ended March 31, 2025.
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 March 31, 2025, and December 31, 2024, the balances of the cash-collateralized letters of credit issued to our customers and other counterparties in the U.S. and international locations other than PPA II were $23.8 million and $131.2 million, respectively.
Pledged Funds — In 2019, pursuant to the PPA IIIb repowering of the Energy Server systems, 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. These funds will be released to us by the end of 2026 as long as the Energy Server systems continue to perform in compliance with our warranty obligations. As of March 31, 2025, and December 31, 2024, the balance of the restricted cash fund was $7.4 million and $7.4 million, respectively.
Contingencies
Indemnification Agreements — See Part II, Item 8, Note 13 — Commitments and Contingencies, section Contingencies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations with customers and certain other business partners. However, we may record charges in the future as a result of these indemnification obligations.
Investment Tax Credits — See Part II, Item 8, Note 13 — Commitments and Contingencies, section Contingencies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
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 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 took place throughout 2024 with an evidentiary hearing scheduled for July 21, 2025. We are unable to predict the ultimate outcome of the arbitration at this time.

Segment Reporting [Abstract]  
Segment Information Segment Information
ASC 280, Segment Reporting, (“ASC 280”) establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Based on the criteria established by ASC 280, our chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer. The CODM reviews consolidated results when making decisions about allocating resources and assessing the performance of the Company as a whole and hence, we have only one reportable segment. We do not distinguish between markets or segments for the purpose of internal reporting.
For discussion of significant segment expenses, other segment items and the Company’s primary measure of segment profitability, refer to Part II, Item 8, Note 14 — Segment Information in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

For the three months ended March 31, 2025 and 2024, we recorded an income tax provision (benefit) of $0.4 million and $(0.5) million on pre-tax losses of $23.0 million and $57.0 million for effective tax rates of (1.9)% and 0.9%, respectively.
The effective tax rate for the three months ended March 31, 2025, and 2024, is lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets.
