PART I

ITEM. 1 BUSINESS

General

Eos Energy Enterprises, Inc. (NASDAQ: EOSE) (“Eos”, “we,” “us,” “our,” or “Company”) is an American energy company and America’s leading innovator in designing, manufacturing and providing zinc-based battery energy storage systems ("BESS"), sourced and manufactured in the United States. The Eos BESS are safe, non-flammable, secure and sustainable alternatives to lithium-ion batteries, making them ideal for utility-scale, microgrid and commercial and industrial long-duration applications.

The Company designs, develops, manufactures and markets zinc‐based energy storage systems intended for utility‐scale, microgrid and commercial and industrial (“C&I”) applications. The Company believes its technology serves as a viable alternative to lithium‐ion (“Li‐ion”) batteries for long‐duration energy storage use cases.

The Company has developed a broad intellectual property portfolio, including multiple patents covering its battery chemistry, mechanical product design, energy block configuration and proprietary software operating system, the Battery Management System (“BMS”). The BMS incorporates Eos‐developed algorithms and utilizes ambient and battery temperature sensors, as well as voltage and current sensors for electrical strings and system‐level monitoring.

The Company currently focuses on the manufacture and sale of turnkey direct current (“DC”) battery energy storage systems and plans to expand its product portfolio to include turnkey alternating current (“AC”) systems. The Company’s primary applications include:

(a) integration with renewable energy systems that are connected to the utility grid;

(b) integration with renewable energy systems that are not grid‐connected;

(d) installations that enable C&I customers to reduce peak energy usage or participate in utility ancillary and demand‐response markets.

These applications are increasingly relevant as overall electricity demand continues to rise, including incremental load growth associated with the expansion of artificial intelligence ("AI"), high‐performance computing ("HPC") and data center infrastructure, which is contributing to greater system capacity needs and grid‐level constraints.

The Company operates a manufacturing facility in Turtle Creek, Pennsylvania, which produces DC energy blocks incorporating the Company’s BMS. The Company also maintains a facility in Warrendale, Pennsylvania, which is not currently operational and is expected to become operational in 2026. Currently, the Company’s primary geographic market is North America, and the Company operates as one operating and reportable segment.

Principal Products and Services

The Company provides an innovative ZnythTM battery energy storage system (“BESS”) engineered to deliver the operational flexibility needed to address rising grid complexity and price volatility. These challenges are being driven by the rapid expansion of renewable energy generation, accelerating electricity demand, including significant increases tied to the growth of artificial intelligence and data center activity and the resulting congestion across the power grid. The Company’s BESS utilizes a proven chemistry made from abundant, non‐precious earth materials in a robust design capable of maintaining performance in extreme temperatures and harsh environments. The system is built for safety, flexibility, scalability and sustainability, and is manufactured in the United States using raw materials primarily sourced domestically. We believe the Company’s Z3 battery module serves as the foundation of its advanced systems. The Z3 module is currently the only U.S.-designed and manufactured battery module that offers utilities, independent power producers, renewable developers and C&I customers a viable alternative to lithium-ion and lead-acid monopolar batteries for critical 3‐ to 12‐hour, or longer, discharge-duration applications. We believe the Z3 battery is reshaping how utility, industrial and commercial customers store and manage power.

In addition to its BESS, the Company currently provides:

(a) a battery management system (“BMS”) that enables remote asset monitoring and analytics to assess the performance and health of the Company’s BESS and to identify potential future performance issues through predictive analytics;

(b) project management services designed to coordinate the installation and integration of the Company’s BESS within a customer’s broader project plan;

(c) commissioning services intended to verify that the customer’s installation of the BESS meets expected performance requirements; and

(d) long‐term maintenance programs designed to support sustained, optimal operating performance of the Company’s systems.

Availability of Raw Materials

The Company procures materials from various third parties and across commodities, including chemicals and substrates, fabricated metal products, plastics, electronics and electrical components. We use both domestic and international raw materials suppliers to create our current Z3 battery module. We will continue to focus on domesticating our supply chain in an economically sustainable manner.

While we believe we have sufficient sources for the materials, components, services and supplies used in our manufacturing activities, we are highly dependent on the availability of essential materials, parts and subassemblies from our suppliers. The predominant raw materials that are required for our Z3 battery product are zinc halide salts, felt, resin, titanium and conductive polymer.

The Company effectively manages its supply chain through close relationships with key suppliers. We engage in formal agreements with our strategic supplier partners and continually look to implement strategies and opportunities to ensure a resilient supply network.

Additionally, based on the latest Internal Revenue Service ("IRS") guidance, the Company believes that our current Z3 battery module feature raw materials sourcing sufficient to qualify for the Domestic Content Bonus awarded by the Inflation Reduction Act’s ("IRA") tax credits.

Industry Overview

We believe the energy storage industry has become a critical component of modern electricity infrastructure. The Company’s solutions support the evolving needs of the power sector and complement existing resources in meeting growing global demand for reliable and flexible energy. As electricity consumption increases, driven in part by the rapid expansion of AI, HPC and data center infrastructure, energy storage plays an essential role in enhancing grid stability, providing capacity support and improving system resilience.

The global market for energy storage continues to demonstrate strong growth, supported by the rising need for grid reliability, increasing system capacity requirements and advancements in storage technologies. We believe the market is positioned for meaningful expansion over the next decade. Key industry growth drivers include grid modernization initiatives, cost reductions across storage technologies, increased electrification and a growing focus on energy security.

Government policies, subsidies and incentives in certain countries are further supporting the development and deployment of energy storage solutions. In the United States, the Department of Energy (“DOE”) has long supported energy storage research and development, and several states have implemented mandates or incentive programs to promote broader adoption.

Energy storage remains a rapidly evolving sector that we believe is foundational to the future of global energy systems. The Eos Z3 BESS offers a differentiated long‐duration solution that can serve as standalone storage and help address capacity constraints and infrastructure challenges across the electricity grid. We believe the technology, safety characteristics, and wide operating range of our BESS position it as a durable and reliable asset for grid operators and customers.

Strategy

The Company continues to invest in the design, development and production of its next‐generation product, the Eos Z3 battery. The Z3 builds upon the same underlying electrochemistry the Company has utilized for nearly a decade. The Eos Z3 is engineered to reduce cost and weight while improving manufacturability and overall system performance. Compared to the Company’s prior Gen 2.3 product, the Z3 incorporates a more cost‐effective design, including a simplified tub structure, approximately 50% fewer cells, and approximately 98% fewer welds per battery module. The Company believes the Eos Z3 will provide customers with approximately twice the energy density per square foot while maintaining the safety and reliability characteristics of the previous generation.

The Company has successfully transitioned to the Eos Z3 platform, enabled by the commissioning and commercial operation of its first fully automated battery manufacturing line. The Z3 leverages the same proven underlying chemistry, which has demonstrated durability over more than 3 million cycles, while incorporating a redesigned mechanical architecture that enhances performance, reduces costs and improves manufacturability. Z3 battery modules have been shipped since the third quarter of 2023, and the transition reflects over fifteen years of accumulated insights and operational experience. The Company believes this experience will continue to drive manufacturing efficiencies as production scales and its state‐of‐the‐art operations expand.

In 2025, the Company introduced DawnOS, a software platform designed to enhance the value, reliability and safety of the Company’s BESS. DawnOS builds upon the Z3 battery architecture through a fully integrated hardware and software solution. It serves as the system’s intelligence layer and is designed to manage large numbers of battery modules in real time. The platform provides precise balancing, dynamic switching and continuous system operation, including in situations where individual modules within a string become imbalanced. DawnOS is intended to increase usable energy per cycle, reduce field service requirements and operate with embedded security and automation features. Through its advanced control capabilities, the Company expects DawnOS to be an integral component of its product portfolio going forward, reflecting its role in improving system resilience, efficiency and overall operational performance.

In 2026, the Company introduced Eos Indensity, an energy storage architecture that uses a spatial intelligence design framework to provide high density storage with flexibility and safety in constrained as well as traditional sites. The system targets up to 1 GWh per acre, roughly four times most incumbent footprints, through stackable Indensity Core units that integrate Eos Z3 battery modules with the Eos DawnOS controls platform. The modular self contained form factor enables efficient transport, simplified installation and long term serviceability. Eos Indensity can be deployed indoors or outdoors, including inside existing buildings. It addresses long duration, response driven use cases across data centers, military bases, manufacturing facilities and critical infrastructure, supported by a domestic FEOC compliant supply chain. The Company expects Indensity to be an integral component of its product portfolio going forward.

The Company believes that the simplicity, flexibility and safety characteristics of its products represent important attributes valued by the market. In addition, the Company benefits from legislative incentives, including the Inflation Reduction Act and the One Big Beautiful Bill Act ("OBBBA"), which provide production tax credits (“PTC”) for domestically manufactured battery components, as well as tax credits available to customers for projects that satisfy domestic content requirements (see “Regulations” in Item 1 – Business). The Company also intends to continue working with a consortium of community organizations, universities and supply chain partners to pursue available funding opportunities under the Bipartisan Infrastructure Law of 2021.

Market Trends and Opportunities

The Company believes the rapid adoption of AI, HPC and data‐intensive technologies is creating significant new demands on global power infrastructure. As AI models grow in scale and data centers expand at an unprecedented pace, energy systems must be equipped to manage increasingly complex load profiles and heightened reliability requirements. The Company sees this shift as a major opportunity for advanced, resilient energy storage solutions that help stabilize grids, support peak demand and ensure uninterrupted power for mission‐critical computing.

Historically, most energy storage deployments have relied on short‐duration systems capable of providing less than four hours of power. The Company anticipates that the next generation of digital infrastructure, particularly

AI‐driven facilities and high‐density compute environments, will require mid‐duration (6–12 hour) BESS capable of managing sustained load fluctuations and alleviating capacity constraints.

The Z3 battery is uniquely positioned to serve this emerging market. It is composed primarily of five earth‐abundant, readily available raw materials with well‐established supply chains, enabling the Company to continue driving down costs as production scales. Although lithium‐ion is currently the installed base leader, zinc‐based batteries are gaining traction in applications prioritizing safety, abundant/recyclable inputs and flexible duration performance under demanding cycle conditions.

Safety is a core strength. As concerns grow regarding lithium‐ion battery risks, such as thermal runaway, fires and explosions, the Company’s non‐flammable, inherently stable chemistry offers a compelling alternative for environments where reliability and safety are paramount. This includes data centers, AI compute campuses and other facilities requiring continuous, secure and risk‐mitigated power. The Z3 technology avoids the failure modes associated with lithium‐ion electrolytes, providing a significantly enhanced safety profile and supporting the Company’s commitment to delivering dependable and robust energy storage solutions.

Intellectual Property

The success of our business depends, in part, on our ability to maintain and protect our proprietary technology, information, processes and know-how. We rely primarily on patent, trademark, copyright and trade secret laws in the United States and similar laws in other countries, confidentiality agreements and procedures and other contractual arrangements. These patents are subject to regulatory approval by the respective governing entity where the patent was filed. A majority of our patents relate to cell chemistry, architecture and battery mechanical design, system packaging and BMS. We continually assess opportunities to seek patent protection for those aspects of our technology, design, methodologies and processes that we believe provide significant competitive advantages.

The Company periodically assesses its patent portfolio in relation to the patents’ utility and materiality to the current operation and future strategy of the business and abandons applications or ceases to maintain patents which are deemed immaterial to our current or future business operations. As of December 31, 2025, we have 31 patent families and 202 patents pending, issued, or published in 30 countries, protecting our technology and system architecture. The Company's key patents, related to its most recent generation product and future products, are not scheduled to expire until 2035 or later.

In addition, the Company relies on trade secret protection and confidentiality agreements to safeguard our interests with respect to proprietary know-how that is not patentable and processes for which patents are difficult to enforce. We believe that many key elements of our manufacturing processes involve proprietary know-how, technology or data that are not covered by patents or patent applications, including technical processes, test equipment designs, algorithms and procedures. All of our research and development personnel have entered into confidentiality and proprietary information agreements with us. These agreements address intellectual property protection issues and requires our employees to assign to us all of the inventions, designs and technologies that Company personnel develop during the course of their employment. We also require our customers and business partners to enter into confidentiality agreements before we disclose any sensitive aspects of our technology or business plans.

Regulations

Governmental Programs and Incentives

Globally, both the operations of our business by us and the ownership of our products by our customers are impacted by various government programs, incentives and other arrangements.

DOE Loan Facility

On November 26, 2024, the Company entered into a note purchase agreement with the United States Federal Financing Bank ("FFB") and the United States DOE Loan Programs Office (“LPO”) ("DOE Loan Facility") pursuant to which, among other things, the DOE provided a guarantee of the Company’s (x) obligations to repay the term loan borrowings provided by the FFB to the Company and evidenced by a future advance promissory note (the “FFB Promissory Note”) and (y) the Company’s other obligations owing to FFB in respect of such guaranteed loan,

and in connection and concurrently therewith, the Company entered into a Loan Guarantee Agreement with the DOE (collectively, such agreements provide for a multi draw term loan facility, the DOE Loan Facility), marking the first Title XVII battery loan closed. The DOE Loan Facility is a key step in advancing the Company's Project American Made Zinc Energy ("AMAZE") and is expected to fund the expansion of Eos’ manufacturing capacity to 8 GWh by 2027 to meet the growing demand for longer duration battery energy storage systems. The DOE Loan Facility provides for up to $303.5 million in funding, including capitalized interest.

The DOE Loan Facility provides for a multi draw term loan facility under a series of at least two and, if the Company elects, up to four tranches of the loan (each, a “Tranche”), subject to the achievement of certain funding conditions, with each Tranche corresponding to the production, maintenance and development and operation of a given production line to be funded using the proceeds of such Tranche and the principal amount of each Tranche consisting of a maximum principal amount designated for such Tranche in the DOE Loan Facility. Each Tranche provides the Company funding for 80% of the Eligible Project Costs (as defined in the DOE Loan Facility) associated with the corresponding production line, with the Company responsible for funding the remaining 20% of the Eligible Project Costs.

As of December 31, 2025, the Company had drawn down $90.9 million under the DOE Loan Facility, utilizing the full commitment available for Tranche 1. The initial draw of $68.3 million was made at an interest rate of 4.791%, for eligible project costs incurred through December 6, 2024. The second draw of $22.7 million was made at an interest rate of 4.286%, for eligible project costs incurred through June 4, 2025. These costs represent Tranche 1 that provided $90.9 million for eligible costs in connection with the design, construction, installation, startup and shakedown of a battery automation line and related tools, with a projected annual production capacity of approximately 1.25 GWh ("Line 1"), as defined in the DOE Loan Facility.

For further discussion, see Note 13, Borrowings, to the Consolidated Financial Statements.

Inflation Reduction Act of 2022

On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 into law. The IRA has significant economic incentives for both energy storage customers and manufacturers for projects placed in service after December 31, 2022. One of the most important features of the IRA is that it offers a 10-year term tax credit, whereas historically similar industrial credits have been shorter in duration. Customers placing new energy storage facilities in service, which include our Gen 2.3 and Z3 BESS, could qualify for investment tax credit (“ITC”). The IRA also offers an extra ten percent credit if the project is in an “energy community” and another ten percent credit if the project satisfies domestic content requirements, which have been set forth. The ten percent bonus for domestic content could represent a strategic advantage for the Company resulting from the Company’s near-sourcing and Made in America strategy, and we currently anticipate that projects utilizing Eos batteries will qualify for the bonus.

The Production Tax Credits under Internal Revenue Code 45X (“PTC”), can be claimed on battery components manufactured in the U.S. and sold to U.S. or foreign customers. These tax credits available to manufacturers include a credit for ten percent of the cost incurred to make electrode active materials in addition to credits of $35 per kWh of capacity of battery cells and $10 per kWh of capacity of battery modules. These credits are cumulative, meaning that companies will be able to claim each of the available tax credits based on the battery components produced and sold through 2029, after which the PTC will begin to gradually phase down through 2032.

One Big Beautiful Bill Act

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act into law, introducing several modifications to the energy-related tax incentives originally established under the Inflation Reduction Act. The OBBBA introduces new limitations related to the sourcing of materials from a prohibited foreign entity ("PFE") for taxable years beginning after July 4, 2025. These provisions restrict eligibility for credits where material assistance is received from such entities. Additionally, the PFE-related restrictions include ownership and effective control related provisions concerning 'specified foreign entities' and 'foreign-influenced entities'.

We believe the following strengths of our business distinguish us from our competitors and position us to capitalize on the expected continued growth in the energy storage market:

•Differentiated Product- The Company believes its ZnythTM BESS offers meaningful performance, safety and operational advantages over traditional lithium‐ion and flow battery systems. Unlike lithium‐ion cells, which must operate within a narrow temperature band to avoid thermal runaway, the ZnythTM BESS functions across a much wider range (-20°C to 50°C). This broad operating window reduces the need for costly thermal management systems, including HVAC and specialized fire suppression.

The ZnythTM BESS also features a static, modular design with no pumps or compressors, lowering maintenance requirements compared to flow batteries. In addition, its flexible charge and discharge capabilities support a wide range of durations and use cases. Lithium‐ion batteries typically have fixed rate parameters and may degrade when operated outside their design specifications, whereas ZnythTM technology is not subject to the same limitations.

Eos batteries are manufactured at zero voltage and zero percent state of charge, they avoid degradation associated with maintaining specific charge levels during idle periods, a requirement for lithium‐ion systems. The Company believes these characteristics position the ZnythTM BESS as a reliable, cost‐efficient and versatile energy storage solution.

•Minimal Supply Chain Constraints- All materials used in the production of the Company’s Z3 battery products are widely available commodity inputs with fewer supply‐chain constraints and limited competition from electric‐vehicle demand. In addition, most of these materials are recyclable through commercially established processes at end of life, supporting responsible material management.

•Proven Technology Solution in the Growing and Evolving Energy Storage Market- As the Company continues to scale manufacturing to gigawatt‐hour (“GWh”) capacity, it expects to benefit from continued growth in the global energy storage market, which BloombergNEF projects will reach approximately 7,250 GWh by 2035. The market is also shifting toward long‐duration energy storage (“LDES”) applications, reflecting the need for systems capable of supporting extended operational requirements. The Company believes its technology is well positioned to meet this demand. While lithium‐ion solutions are generally optimized for shorter‐duration applications, the performance characteristics of the Company’s batteries improve as storage duration increases, making the Z3 a strong fit for long‐duration use cases.

•Experienced Technology Team Focused on Continuous Innovation- The Company’s research and development team is responsible for advancing its technology platform and expanding and protecting its intellectual property portfolio. The Company believes that continued investment in research and development will support improvements in efficiency, energy density, functionality and reliability, while further reducing the cost of its battery solutions.

The Company is also focused on applying its technical expertise to enhance its BMS, broaden operating capabilities, and improve overall system performance. These efforts are expected to support the optimization of the Company’s energy management solutions, enabling operating parameters to be aligned with specific applications and expanding the range of use cases for the ZnythTM BESS.

•Established Global Sales Channels Anchored with Top-Tier Customers- We sell products directly to the electric utility industry and through sales channels to the commercial and industrial market.

ITEM 1A. RISK FACTORS

In addition to the factors discussed elsewhere in this Report, the following risks and uncertainties could materially and adversely affect the Company’s business, financial condition, results of operations and cash flows.

Risk Factors Summary

The following is a summary of the principal risks that could adversely affect our business, operations and financial results.

Risks Related to Our Business and Industry

•Our history of losses puts the onus on us to deliver on our potential for significant business growth and to improve our manufacturing processes to achieve sustained, long-term profitability and commercial success.

•The relatively recent commercialization of our products makes it difficult to evaluate our prospects.

• Failure to deliver the benefits offered by our technologies, or the emergence of improvements to competing technologies, could reduce demand for our products and harm our business.

•As we endeavor to expand our business, we will incur significant costs and expenses, which could outpace our cash reserves. Unfavorable conditions or disruptions in the capital and credit markets may adversely impact business conditions and the availability of credit.

•Our success depends on the continuing contributions of our key personnel, and the loss of services of any principal member of our management team could adversely affect our business.

•Labor disputes could disrupt our ability to serve our customers and/or lead to higher labor costs.

•The imposition of tariffs, sanctions, restrictions on imports or other trade barriers between the United States and various countries may impact our revenue and results of operations.

Risks Related to Our Products and Manufacturing

•Compared to traditional Li-ion energy storage technologies, our cells and modules have less power density and may be considered inferior to competitors’ products.

•We have limited manufacturing experience and could experience difficulty producing commercial volumes of the battery storage system, establishing manufacturing capacity to scale and in meeting potential cost savings and efficiencies from anticipated improvements to our manufacturing capabilities.

•We may experience delays, disruptions, or quality control problems in our manufacturing operations.

•A disruption in the operations of our manufacturing facility could have a significant negative impact on our ability to manufacture our products.

•We may not have sufficient insurance coverage to cover business continuity.

•Defects or performance problems in our products could result in loss of customers, reputational damage and decreased revenue, facing warranty, indemnity and product liability claims that may arise from defective products.

•We are heavily dependent on third-party suppliers and contractors. Supply chain issues could adversely affect our operations and financial results.

•If we elect to expand our production capacity by constructing one or more new manufacturing facilities, we may encounter challenges relating to the construction, management and operation of such facilities.

Risks Related to Our Future Growth

•If we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high levels of customer service, or adequately address competitive challenges.

•Our growth prospects depend on our ability to capitalize on market opportunities.

•If we fail to meet the covenants in either the DOE Loan Facility or the Credit Agreement, we may be subject to default under the credit facilities, which could have a material adverse effect on our business.

•The Company may need to seek alternative sources of capital, or risk its ability to continue operations, in the event it fails to meet a funding condition under the terms of the DOE Loan Facility or in the event that the government enacts laws and governmental regulations that could affect the availability of funding under the DOE Loan Facility.

•A substantial number of shares of the Company’s common stock that are issuable upon the exercise or conversion of securities issued under the Credit Agreement and the SPA are subject to a contractual lockup.

•Our results of operations may fluctuate from quarter to quarter, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fall below expectations, resulting in a decline in the price of our common stock.

Risks Related to Our United States Operations

•Some of our customers receive federal, state and local government incentives for renewable energy solutions. The reduction, elimination or expiration of government subsidies and economic incentives related to renewable energy solutions could reduce demand for our technologies and harm our business.

•We have operations in the United States, which exposes us to multiple federal, state and local regulations.

•Changes in applicable law, regulations or requirements, or our material failure to comply with any of them, can increase our costs and have other negative impacts on our business.

Risks Related to Intellectual Property

•If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, then our business and results of operations could be materially harmed.

•Third parties may assert that we are infringing, misappropriating or otherwise violating their intellectual property rights, which could divert management’s attention, cause us to incur significant costs and prevent us from selling or using the technology to which such rights relate.

Risk Related to Our Securities

•Under the terms of the Credit Agreement, the SPA and the securities issued thereunder, current stockholders may be subject to significant dilution, and the voting power of the currently outstanding common stock could be significantly diluted.

•We currently have a significant number of outstanding securities outstanding that are exercisable for or convertible into our common stock, which could result in significant additional dilution and downward pressure on our stock price. Future issuances of our common stock, including common stock that may be issuable pursuant to outstanding warrants or other convertible securities, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

•Our stock price may be volatile and may decline regardless of our operating performance.

•Future resales of our common stock may cause the market price of our securities to drop significantly, even if our business is doing well.

•We do not intend to pay dividends on our common stock in the foreseeable future and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

•We are a “smaller reporting company” and, because we have opted to use the reduced reporting requirements available to us, certain investors may find investing in our securities less attractive.

Risk Factors

An investment in our securities involves a high degree of risk. You should carefully consider the risks described below before making an investment decision. Our business, prospects, financial condition, or operating results could be harmed by any of these risks, as well as other risks not known to us or that we consider immaterial as of the date of this Form 10-K. The trading price of our securities could decline due to any of these risks, and, as a result, you may lose all or part of your investment.

Risks Related to Our Business and Industry

Our history of losses puts the onus on us to deliver on our potential for significant business growth and to improve our manufacturing processes to achieve sustained, long-term profitability and commercial success.

We have had net losses and negative operating cash flows each fiscal year since inception of our business. For the years ended December 31, 2025 and 2024, we had $969.6 million and $685.9 million in net losses, respectively. We expect to continue to incur losses and experience negative operating cash flows for the foreseeable future, as we anticipate continued investment in the development and launch of product with outside capital at the expense of short-term profitability.

Although our available capital has increased substantially through the issuance of convertible notes and other financing, we continue to have limited resources relative to certain of our competitors, especially certain Li-ion manufacturers that have a longer history, are part of large multinational corporations and are already operating at a profit. To achieve profitability as well as long-term commercial success, we must continue to execute our plan to expand our business, which will require us to deliver on our existing global sales pipeline in a timely manner,

increase our production capacity, improve our cost profile, grow demand for our products and seize new market opportunities by leveraging our proprietary technology and its manufacturing processes for novel solutions. Failure to do one or more of these things could prevent us from achieving sustained, long-term commercial success.

As a growth company in the early commercialization stage of its lifecycle, Eos is subject to inherent risks and uncertainties associated with the development of an enterprise. Our revenues may not grow as expected for a number of reasons, many of which are outside of our control, including a decline in global demand for battery storage products, increased competition, or our failure to continue to capitalize on growth opportunities. In addition, although we have achieved sales of our products to potential customers, it is not clear to what extent, if any, the products will be profitable and when. The costs of goods associated with production of our battery storage system are significant. While we are working to optimize our supply chain, improve the speed and efficiency of our manufacturing processes, and lower the cost of other input costs such as raw material and conversion costs, there can be no assurance that we will be successful in these efforts. If we are not able to sustain revenue growth, reduce cost and continue to raise the capital necessary to support operations, our failure to achieve or maintain profitability could negatively impact the value of our common stock. Even if we do achieve profitability when expected, we may be unable to sustain or increase our profitability in the future.

While, in order to execute our development strategy, we have historically relied on outside capital through the issuance of equity, debt, and borrowings under financing arrangements (collectively “outside capital”) to fund our cost structure. Moving forward, our primary objective is to achieve a scale of operations that generates sufficient internal cash flow to sustain our business and eliminate our historical reliance on outside capital. While we intend to reach and maintain profitability, there can be no assurance we will be able to achieve such profitability or do so in a manner that does not require our continued reliance on outside capital. Moreover, while we have historically been successful in raising outside capital, there can be no assurance we will be able to continue to obtain outside capital in the future or do so on terms that are acceptable to us.

The relatively recent commercialization of our products makes it difficult to evaluate our future prospects.

Since our inception, we have sold a limited quantity of Eos ZnythTM DC battery systems to our customers. We began commercializing our products in mid-2018, and while our research and development activities successfully established the efficiency of our chemistry, we struggled to incorporate our proven technologies into an effective manufacturing design prior to 2018.

We continue to invest in the design and development of the next generation product, the Z3 battery which builds off the same electrochemistry that has not fundamentally changed for the better part of a decade. The Z3 battery is designed to reduce cost and weight and improve manufacturability and system performance. The Eos Z3 transition is fully underway, and the first semi-automated battery manufacturing line is installed and has started commercial production. The Company started delivery of its Z3 battery modules in the third quarter of 2023.

Our success will depend on our ability to manufacture products at scale and low cost while timely meeting customers’ demands and overcome any negative perception in the market related to our historical manufacturing challenges, and we may not be able to generate sufficient customer confidence in our latest designs and ongoing product improvements and lower the cost due to economies of scale. Our inability to predict the extent of customer adoption of our proprietary technologies in the already-established traditional energy storage market makes it difficult to evaluate our profitability and future prospects.

Failure to deliver the benefits offered by our technologies, or the emergence of improvements to competing technologies, could reduce demand for our products and harm our business.

We believe that, compared to Li-ion batteries, our energy storage solutions offer significant benefits, including the use of widely-available and low-cost materials with no rare earth or toxic components, recyclability at end-of-life, an over twenty (20) year product life requiring minimal maintenance, and a wide thermal operating range that eliminates the need for fire suppression and HVAC, which would otherwise be required for use with Li-ion batteries.

The rates at which electricity is available from a customer’s local electric utility company is subject to change and any changes in such rates may affect the relative benefits of our energy storage systems. Further, if our

manufacturing costs do not decrease to the extent we intend, or if our expectations regarding the operation, performance, maintenance and disposal of our products are not realized, we could have difficulty marketing our products as a superior alternative to already-established technologies and impact the market reputation and adaptability of our products. Developments of existing and new technologies could improve their cost and usability profile, reducing any relative benefits currently offered by our products which would negatively impact the likelihood of our products gaining market acceptance. Additionally, our competitors may lower their sales prices in response to market competition. Some competitors, particularly in China, may have lower operating expenses due to greater vertical integration and supportive regulatory frameworks, allowing them to operate with minimal or even negative margins over time. This has hindered and may in the future hinder our ability to compete in certain markets, which may lead to reduced net sales and negatively impact our operating results. In response to such competitive pressures, we may also choose to adjust our pricing strategy in certain markets or reduce our margin expectations, which could further affect our financial performance.

A decline in lithium prices may result in increased competition from traditional lithium-ion (“Li-ion”) batteries and adversely affect the demand for our products.

Currently, global lithium available supply exceeds demand. Decreases in the price oflithium, a key component of traditional Li-ion batteries, may increase the competitiveness of the traditional Li-ion batteries relative to the zinc-based energy storage solutions we provide. Mineral prices fluctuate widely and are affected by numerous factors beyond our control such as global and regional supply and demand, interest rates, exchange rates, inflation or deflation, fluctuation in the value of the United States dollar and foreign currencies, and the political and economic conditions of mineral-producing countries throughout the world. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in a decrease in lithium prices, which may adversely affect our business and results of operations.

Under certain circumstances, our customers can modify or terminate their contracts.

We have ongoing arrangements with our customers and target customers. Some of these arrangements are evidenced by early-stage agreements that are intended to be used to memorialize desired development with a party but will require renegotiation at later stages of development or production or more definitive agreements that have yet to be negotiated or executed, each of which may or may not materialize into next-stage contracts or long-term contract partnership arrangements. If these arrangements are modified or terminated or if we are unable to enter into next-stage contracts or long-term operational contracts, our business, prospects, financial condition, and operating results may be materially adversely affected. Modifications or termination of our existing contracts may also directly impact our business, prospects and financial condition, including by reducing backlog by significant amounts.

As we endeavor to expand our business, we will incur significant costs and expenses, which could outpace our cash reserves. Unfavorable conditions or disruptions in the capital and credit markets may adversely impact business conditions and the availability of credit.

We expect to incur additional costs and expenses in the future related to the continued development and expansion of our business, including in connection with expanding our manufacturing capabilities to significantly increase production capacity, developing our products, maintaining and enhancing our research and development operations, expanding our sales, marketing, and business development activities in the United States and internationally, and growing our project management, field services and overall operational capabilities for delivering projects. We do not know whether we will be able to reduce our manufacturing cost and grow our revenue rapidly enough to absorb these costs or the extent of these expenses or their impact on our results of operations.

Disruptions in the global capital and credit markets as a result of an economic downturn, economic uncertainty, changing or increased regulation, or failures of significant financial institutions could adversely affect our customers’ ability to access capital and could adversely affect our access to liquidity needed for business in the future. Our business could be hurt if we are unable to obtain additional capital as required, resulting in a decrease in our revenues and profitability.

Our success depends on the continuing contributions of our key personnel, and the loss of services of any principal member of our management team could adversely affect our business.

We rely heavily on the services of our key executive officers. We are investing significant resources in developing new members of management as we complete our restructuring and strategic transformation, and the loss of services of any principal member of our management team could adversely affect our business. The competition for qualified personnel is intense in our industry, and we may not be successful in attracting and retaining enough qualified personnel to support our anticipated growth. We also cannot guarantee that any employee will remain employed with us for any definite period since all of our employees, including our key executive officers, serve at-will and may terminate their employment at any time for any reason.

The Company’s Compensation Committee of the Board of Directors is committed to working with the management to design compensation plans that attract, retain and motivate the Company’s executives and support business objectives that create shareholder value. In addition, the Board of Directors has implemented procedures to plan for the effective succession of senior management and key personnel. However, we still depend on the experience of our senior management team, including our chief executive officer, chief financial officer and chief accounting officer, and other key personnel, each of whom would be difficult to replace in the event of an unforeseen departure from the Company. Despite successfully managing recent turnover, the loss of any such personnel could have a material adverse effect on our business and our ability to implement our business strategy. All of our employees, including our senior management, are free to terminate their employment relationships with us at any time. We do not maintain key-person insurance for any of our employees, including senior management. In addition, changes and replacement, as well as transition in senior executive leadership could adversely affect our relationships with clients, customers, and employees. We must successfully integrate new key personnel whom we hire within our organization in order to achieve our operating objectives.

Additionally, our ability to attract qualified personnel, including senior management and key technical personnel, is critical to the execution of our growth strategy. Competition for qualified senior management personnel and highly skilled individuals with technical expertise is extremely intense. We face and are likely to continue to face challenges identifying, hiring, and retaining qualified personnel in all areas of our business. In addition, integrating new employees into our team could prove disruptive to our operations, require substantial resources and management attention, and ultimately prove unsuccessful. Our failure to attract and retain qualified senior management and other key technical personnel could limit or delay our strategic efforts, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Changes in accounting principles or their application to us could result in unfavorable accounting charges or effects, which could adversely affect our operating results and prospects.

We prepare our financial statements in accordance with accounting principles generally accepted in the United States. The accounting for our business is subject to change based on the evolution of our business model, interpretations of relevant accounting principles, enforcement of existing or new regulations, and changes in policies, rules, regulations, and interpretations, of accounting and financial reporting requirements of the SEC or other regulatory agencies. A change in any of these principles or guidance, or in their interpretations or application to us, may have a significant effect on our reported results, as well as our processes and related controls, and may retroactively affect previously reported results. The adoption of new or revised accounting principles may require us to make changes to our systems, processes and internal controls, which could have a significant effect on our reported financial results and internal controls, cause unexpected financial reporting fluctuations, retroactively affect previously reported results or require us to make costly changes to our operational processes and accounting systems upon our following the adoption of these standards. Any of these results could adversely affect our business.

If our internal controls are found to be ineffective, our results of operations or our stock price may be adversely affected.

Our most recent evaluation resulted in our conclusion that, as of December 31, 2025, our internal controls over financial reporting were effective. We believe that we currently have adequate internal control procedures in place for future periods. However, if our internal control over financial reporting is found to be ineffective, investors may lose confidence in the reliability of our financial statements, which may adversely affect our results of operations or stock price.

The failure or breach of our network or Information Technology ("IT") systems, including as a result of a cybersecurity breach, could affect our sales and operations.

From time to time, we may face attempts by others to gain unauthorized access to our network or IT systems through various forms of the Internet or try to introduce malicious software to our network or IT systems, including our BMS. We or our products may be a target of computer hackers, organizations or malicious attackers who attempt to:

•gain access to our systems, network or data centers or those of our customers;

•steal proprietary information related to our business, products, employees and customers; or

•interrupt our infrastructure or those of our customers.

To date, no attempts to gain unauthorized access to our network or IT systems have resulted in any material adverse impact to our business or operations; however, there can be no guarantee that such intrusions will not be material in the future. While we seek to detect and investigate all unauthorized attempts and attacks against our IT systems, network and products, and to prevent their recurrence where practicable through changes to our internal processes and tools and/or changes to our products, we remain potentially vulnerable to additional known or unknown threats, such as, among other things, malware and computer virus attacks, ransomware attacks, social engineering attacks (including phishing attacks), credential stuffing, terrorist attacks, civil unrest, military conflict, supply chain attacks, or denial-of-service attacks. In addition to intentional third-party cybersecurity breaches, the integrity and confidentiality of Company and customer data may be compromised as a result of human error, fraud or malice on the part of our employees or third parties, product defects, software bugs, programming errors, design flaws, server malfunctions, software or hardware failure or other technological failures, or bad weather or natural disasters. Such threats are evolving, may be difficult for long periods of time, and may see their frequency increased and effectiveness enhanced by the use of AI. Any integration of AI in our or any third-party providers’ operations, products or services is expected to pose new or unknown cybersecurity risks and challenges. Further, cybersecurity risks may be heightened in connection with ongoing global conflicts such as the military conflict between Russia and Ukraine and the military conflict between Israel and Hamas. Cybersecurity breaches, whether successful or unsuccessful, and other IT system or network interruptions, including those resulting from human error and technological failures, could result in us incurring significant costs related to, for example, rebuilding internal systems, reduced inventory value, providing modifications to our products and services, defending against litigation, responding to regulatory inquiries or actions, paying damages, or taking other remedial steps with respect to third parties.

Our IT infrastructure is currently managed by a third party Managed Services Provider ("MSP"). While we regularly review the cybersecurity tools and other security protection provided by this MSP, and this MSP regularly runs intrusion and other security tests on services provided to us, there can be no guarantee that a failure or breach of such systems will not occur. While we generally perform cybersecurity diligence on our other key service providers, we do not control our service providers and our ability to monitor their cybersecurity is limited. Some of our service providers may store or have access to our data and may not have effective controls, processes, or practices to protect our information from loss, unauthorized disclosure, unauthorized use or misappropriation or cybersecurity breaches. A vulnerability in our service providers’ software or systems, a failure of our service providers’ safeguards, policies or procedures, or a cybersecurity breach affecting any of these third parties could harm our business.

We operate a few IT systems throughout our business that could fail for a variety of reasons, including the threats of unauthorized intrusions and attackers and any other known or unknown threats described above. If such failures were to occur, we may not be able to sufficiently recover to avoid the loss of data or any adverse impact on our operations that are dependent on such IT systems. This could result in lost sales as we may not be able to meet the demands for our product.

Furthermore, because our IT systems are essential for the exchange of information both internally and in communicating with third parties, including our suppliers and manufacturers, cybersecurity breaches and other failures or interruptions to our systems, products or networks could potentially lead to the unauthorized access to or release of sensitive, confidential, proprietary or personal data or information or intellectual property, improper use of our systems, or, unauthorized access, use, disclosure, modification or destruction of information or defective products. If these cybersecurity breaches continue, our operations and ability to communicate both internally and with third parties may be negatively impacted. Additionally, if we try to remediate our cybersecurity problems, we could face significant unplanned costs or capital investments and any damage or interruption could have a material adverse effect on our reputation, business, financial condition, and results of operations. Additionally, we cannot be certain that our insurance coverage will be adequate for data security liabilities actually incurred, that insurance will continue to be available to us on economically reasonable terms, or at all, or that our insurer will not deny coverage as to any future claim.

Internal system or service failures, or failures in the systems or services of third parties on which we rely, could disrupt our business and impair our ability to effectively provide our services and products to our customers, which could damage our reputation and adversely affect our business.

Any system or service disruptions, including to our IT systems managed by a MSP, if not anticipated and appropriately mitigated, could materially and adversely affect our business. We, and the service providers on which we rely, are also subject to systems failures, including network, software or hardware failures, whether caused by us, third-party service providers, cybersecurity threats, malicious insiders, malware and computer virus attacks, ransomware attacks, social engineering attacks, supply chain attacks, human error, software bugs, programming errors, design flaws, other software or hardware failures, bad weather, natural disasters, power shortages, terrorist attacks, pandemics or other events, which could cause loss of data and interruptions or delays in our business, cause us to incur remediation costs, subject us to claims and damage our reputation. In addition, the failure or disruption of our communications, or those of our service providers, could cause us to interrupt or suspend our operations or otherwise adversely affect our business. Our property and business interruption insurance may be inadequate to compensate us for all losses resulting from any system or operational failure or disruption. As a result, we could suffer material financial and reputational losses in the future from any internal system or service failures, or failures in the systems or services of third parties on which we rely, or the perception thereof, whether or not this perception is correct.

Uncertainty in the development, deployment or use of AI in our products and services, as well as our business more broadly, may adversely affect our business, financial condition, and results of operations.

As with many new and emerging technologies, AI presents numerous risks and challenges that could adversely affect our business. The development, deployment and use of AI technology remains in early stages and ineffective or inadequate development or application practices by us or third parties may result in unintended consequences. For example, if the models underlying the AI are, or are perceived to be, incorrectly designed or implemented, trained or reliant on incomplete, inadequate, inaccurate, biased or otherwise poor quality data, or on data to which we do not have sufficient rights or in relation to which we and/or the providers of such data have not implemented sufficient legal compliance measures (including with respect to the processing and protection of such data), used without sufficient oversight and governance to ensure their responsible and ethical use, and/or adversely impacted by unforeseen defects, technical challenges, cybersecurity threats or material performance issues, then our business, as well as our reputation, could suffer or we could incur liability resulting from harm to individuals, civil claims or the violation of laws or contracts to which we are a party.

There also may be real or perceived social harm, unfairness or other impacts to privacy, employment or other social issues or outcomes that undermine public confidence in the use and deployment of AI. On the other hand, if we fail to keep pace with rapidly evolving technological developments in AI, our competitive position and business may suffer. Our competitors or other third parties may adopt AI capabilities more quickly or more effectively than we do, which could adversely impact our ability to compete. In addition, developing, testing, and deploying resource-intensive AI solutions may require additional investment and increase our costs, and there can be no assurance that the usage of or our investments in such AI technologies will always enhance our products or services or be

beneficial to our business, including our efficiency or profitability. Any of the foregoing may adversely affect our business, financial condition, results of operations and prospects.

Further, the legal and regulatory landscape surrounding AI is rapidly evolving and uncertain, including in the areas of intellectual property, cybersecurity, privacy and data protection. For example, there is uncertainty around the validity and enforceability of intellectual property rights related to use or development of AI tools. Compliance with new or changing laws, regulations or industry standards related to AI may impose significant operational costs and may limit our ability to develop, deploy or use AI technologies in certain use cases. Failure to appropriately respond to this evolving landscape may result in legal liability, regulatory action or reputational harm.

The nature of our business exposes us to potential legal proceedings or claims that could adversely affect our operating results. These claims could conceivably exceed the level of our liability insurance coverage.

We are a party to lawsuits in the normal course of our business. Litigation can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. Responding to lawsuits brought against us, or legal actions that we may initiate, can be expensive and time-consuming. Unfavorable outcomes from these claims and/or lawsuits could adversely affect our business, results of operations, or financial condition and cash flows, and we could incur substantial monetary liability and/or be required to change our business practices. See Part I, Item 3, “Legal Proceedings.”

Our business may expose us to claims for personal injury, death or property damage resulting from the use of our products or from employee related matters. Additionally, we could be subject to potential litigation associated with compliance with various laws and governmental regulations at the federal, state or local levels, such as those relating to the protection of persons with disabilities, employment, health, safety, security and other regulations under which we operate.

We carry comprehensive insurance, subject to deductibles, at levels we believe are sufficient to cover existing and future claims made during the respective policy periods. However, we may be exposed to multiple claims, and, as a result, could incur significant out-of-pocket costs before reaching the deductible amount, which could adversely affect our financial condition and results of operations. In addition, the cost of such insurance policies may increase significantly upon renewal of those policies as a result of general rate increases for the type of insurance we carry as well as our historical experience and experience in our industry. Although we have not experienced any material losses that were not covered by insurance, our existing or future claims may exceed the coverage level of our insurance, and such insurance may not continue to be available on economically reasonable terms, or at all. If we are required to pay significantly higher premiums for insurance, are not able to maintain insurance coverage at affordable rates or must pay amounts in excess of claims covered by our insurance, then we could experience higher costs that could adversely affect our financial condition and results of operations.

Labor disputes could disrupt our ability to serve our customers and/or lead to higher labor costs.

As of December 31, 2025, we have 787 full-time employees.

Approximately 420 production and maintenance employees at our facilities in Turtle Creek and East Pittsburgh, Pennsylvania are represented by the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO/CLC (“USW”).

We entered our first collective bargaining agreement (“CBA”) with USW applicable to the USW-represented employees on February 14, 2025, and the agreement was ratified and became effective on February 19, 2025 and expires on April 30, 2028. The CBA retains a probationary period and existing entry-level wage rates for new employees, provides seniority-based wage progression for entry-level positions and includes general wage increases for other positions. No wage increases become effective until May 1, 2026. The CBA allows for employee participation in existing and future Company benefits, including 401(k) and health and welfare benefits, as offered to our other non-represented employees. The wage and benefit costs agreed in the CBA do not materially increase our previously planned budgetary expenditures at our facilities.

The CBA also allows for substantial operational flexibility with broad management rights, subcontracting rights, flexible shift and overtime scheduling and work rules to preserve reliability and performance of the production facilities. Finally, the CBA contains other common agreement provisions, including non-discrimination, no-strike/no-lockout, union security, safety, discipline and grievance and arbitration procedures.

We maintain a positive and collaborative relationship with the USW, which led to relatively quick agreement on CBA terms. Management considers union relations to be good and the USW as a valuable partner for workforce training and management.

The imposition of tariffs, sanctions, restrictions on imports or other trade barriers between the United States and various countries may impact our revenue and results of operations.

Beginning in early 2025, the current U.S. administration has imposed significant tariffs on imports under multiple legal authorities, some targeting specific countries or products, and others applying on a global basis. Numerous other countries have imposed retaliatory tariffs or other import measures in response to the U.S.’s actions, and the scope and amount of tariffs has changed repeatedly over the course of the past year through the introduction of new tariffs, as a result of trade negotiations and through exemptions unilaterally granted by the U.S. government. Certain of the tariffs are also subject to ongoing legal challenge, the results of which are uncertain. If maintained, these tariffs and other potential tariffs yet to be announced or imposed may have an adverse impact on general economic conditions and our business, the exact outcomes of which are uncertain and depend on various factors, such as negotiations between the U.S. and China or other foreign countries, the duration of such tariffs, the responses of other countries or regions to such tariffs, the actual increases in the costs of imported foreign products and raw materials, and exemptions or exclusions that may be granted.

Further changes in U.S. tariffs are likely, though there is significant uncertainty as to the nature and scope of such changes. Should tariffs increase and be sustained for an extended period of time, our inventory acquisition and carrying costs may be increased, which costs may be passed on to us and consumers through higher prices for our products. These increased prices may adversely impact our new product sales and demand for such products, potentially impacting our ability to sell them profitably. It is difficult to predict what further trade-related actions governments may take, which may include additional or increased tariffs and trade restrictions, and we may be unable to quickly and effectively react to such actions, which could result in supply shortages and increased costs.

We cannot predict whether, and to what extent, there may be changes to international trade agreements or whether quotas, duties, tariffs, exchange controls or other restrictions on our products will be changed or imposed. If we are unable to source our products from the countries where we wish to purchase them, either because of regulatory changes or for any other reason, or if the cost of doing so increases, it could have a material adverse effect on our business, financial condition and results of operations. Furthermore, imposition of tariffs may result in local sourcing initiatives, or other developments that make it more difficult to sell our products in foreign countries, which would negatively impact our business and operating results.

Risks Related to Our Products and Manufacturing

We must obtain Underwriters Laboratories ("UL") and other related certifications for our future generations of product.

Our existing generation of battery systems has received Underwriters Laboratories ("UL") 1973 and 9540 certifications and has been tested for UL 9540A. Based on these North American certifications, we also intend to expand our current generation of battery systems product certification to other national standards such as European Conformity (“CE”) marking in the European Union and the international certification of the International Electrotechnical Commission (“IEC”). We also intend to obtain the UL certification and all applicable safety standards for our future products. Failure to obtain UL, IEC or CE certification would have a significant impact on our revenues, as such certifications are required by most of our customers. As Battery Storage is a relatively new market segment, additional rules will be introduced and regulation changes will occur. We must continue to adapt and ensure conformity to new standards and regulations introduced in the market.

Compared to traditional Li-ion energy storage technologies, our cells and modules have less power density and may be considered inferior to competitors’ products.

While the energy density of the Eos Z3 battery enclosure product is significantly improved compared to the Eos Gen 2.3 enclosure product, and we believe that for certain installation sites the Eos Z3 systems may now equal Li-ion energy density per acre of land, traditional Li-ion cells and modules continue to offer higher power density than Eos cells and modules. The differences in power density become lower when comparing full size Li-ion systems to Eos Z3 systems due to the differences in auxiliary loads required by Li-ion systems and safety spacing between enclosures required by Li-ion, however, if customers were to place greater value on power density on a cell and module basis, then we could have difficulty positioning our batteries as a viable or compelling alternative to traditional Li-ion batteries and our business would suffer.

We have limited manufacturing experience and could experience difficulty in producing commercial volumes of the battery storage system, establishing manufacturing capacity to scale and in meeting potential cost savings and efficiencies from anticipated improvements to our manufacturing capabilities.

We have limited experience in commercial manufacturing of the battery storage system. On August 21, 2019, we entered into a joint venture agreement with Holtec and formed Hi-Power, which was owned 51% by Holtec and 49% by us. We acquired the 51% equity interest owned by Holtec in April 2021. Because we have limited prior commercial manufacturing experience, we may incur manufacturing inefficiencies, delays or interruptions. Our current manufacturing and testing processes do not require significant technological or production process expertise. However, any change in our processes could cause one or more production errors, requiring a temporary suspension or delay in our production line until the errors can be researched, identified, and properly addressed and rectified. This may occur particularly as we introduce new products, modify our engineering and production techniques, and/or expand our capacity. In addition, our failure to maintain appropriate quality assurance processes could result in increased product failures, loss of customers, increased warranty reserve, decreased production and logistical costs and delays. Any of these developments could have a material adverse effect on our business, financial condition and results of operations.

To date, we have only manufactured batteries in limited quantities for a limited number of commercial customers. The output achieved to date is a fraction of what the Company expects will be necessary for full commercialization and to meet the demand we see in the market for our product. The manufacturing process for commercial scale is being refined and improved. There are risks associated with scaling up manufacturing to commercial volumes including, among others, technical or other problems with process scale-up, process reproducibility, stability issues, quality consistency, timely availability of raw materials and cost overruns. There is no assurance that we will be successful in establishing a larger-scale commercial manufacturing process that achieves our objectives for manufacturing capacity and cost per battery, in a timely manner or at all. If we are unable to produce sufficient quantities of product for commercialization on a timely basis and in a cost-effective manner, the Company's commercialization efforts would be impaired which could materially affect our business, financial condition, results of operations and growth prospects.

We may experience delays, disruptions, or quality control problems in our manufacturing operations.

Our operations require significant amounts of certain components and raw materials. We deploy a continuous, company wide process to source the components and raw materials from a few suppliers. If we are unable to source these components or raw materials, our operations may be disrupted, or we could experience a delay or halt in certain of our manufacturing operations. We believe that our supply management and production practices are based on an appropriate balancing of the foreseeable risks and the costs of alternative practices. Nonetheless, reduced availability or interruption in supplies, whether resulting from more stringent regulatory requirements, supplier financial condition, increases in duties and tariff costs, disruptions in transportation, an outbreak of a severe public health pandemic, severe weather, the occurrence or threat of wars and other geopolitical conflict could have an adverse effect on our financial condition, results of operations and cash flows.

Some of our customers may experience project delays as a result of delays in site selection and preparation, procedures of obtaining necessary permissions and establishing grid connections. These delays have impacted, and may, from time to time, continue to impact the timing of our product deliveries and our results of operations.

A disruption in the operations of our manufacturing facility could have a significant negative impact on our ability to manufacture our products.

We currently rely on a single manufacturing site in Turtle Creek, Pennsylvania to manufacture our products, and we expect our facility in Warrendale, Pennsylvania to become operational in 2026. As a result, a sustained or repeated interruption in the manufacturing of our products due to labor shortage, fire, flood, war, pandemic or natural disasters of the current or future facilities may interfere with our ability to manufacture our products and fulfill customers’ demands in a timely manner. Failure to manufacture our products and meet customer demands would impair our ability to generate revenues which would adversely affect our financial results.

Defects or performance problems in our products could result in loss of customers, reputational damage, and decreased revenue, facing warranty, indemnity and product liability claims that may arise from defective products.

Since our inception, our business objectives have been focused on producing a safe, low-cost grid-scale energy storage solution to meet the increasing demand for and adoption of renewable energy generation assets. Our Z3 battery design has, after years of research and prototype development, resulted in robust control of cell-to-cell spacing using a method which can easily be scaled for mass manufacturing production.

Although our products meet our stringent quality requirements, we have experienced quality issues in the field and our products may contain undetected errors or defects, especially when first introduced or when new generations of products are released. Errors, defects, or poor performance can arise due to design flaws, defects in raw materials, components or manufacturing difficulties or products used outside of recommended parameters or maintenance programs which can affect the quality of our products. In addition, our BMS software may contain errors, bugs, vulnerabilities (including to cyber attacks), design defects or technical limitations. Some errors, bugs or vulnerabilities inherently may be difficult to detect. Any actual or perceived errors, bugs, vulnerabilities, defects, or poor performance in our products could result in the replacement or recall of our products, shipment delays, rejection of our products, damage to our reputation, legal claims, lost revenue, diversion of our engineering personnel from our product development efforts, and increases in customer service and support costs, all of which could have a material adverse effect on our business, financial condition and results of operations.

Furthermore, defective components may give rise to warranty, indemnity, or product liability claims against us that exceed any revenue or profit we receive from the affected products. Generally, our product comes with an initial manufacturing warranty. We also offer customers an extended performance warranty of up to twenty-five (25) years at an additional cost to the customer. The price charged for any such extended warranty is based on the use case of the customer and the additional performance that such customer desires. For extended warranties, this may require system augmentation or battery replacements, which would be provided at no additional charge beyond the price of the extended warranty paid by such customer.

While we accrued reserves for warranty claims, our estimated warranty costs for previously sold products may change to the extent future products are not compatible with earlier generation products under warranty. Our warranty accruals are based on various assumptions, which are based on a short operating history. As a result, these assumptions could prove to be materially different from the actual performance of our systems, causing us to incur substantial unanticipated expense to repair or replace defective products in the future or to compensate customers for defective products. Our failure to accurately predict future claims could result in unexpected volatility in, and have a material adverse effect on, our financial condition.

If one of our products were to cause injury to someone or cause property damage, due to a result of product malfunctions, defects, or improper installation, we could be exposed to product liability claims. We could incur significant costs and liabilities if we are sued and if damages are awarded against us. Further, any product liability claim we face could be expensive to defend and could divert management’s attention. The successful assertion of a product liability claim against us could result in potentially significant monetary damages, penalties or fines, subject us to adverse publicity, damage our reputation and competitive position, and adversely affect sales of our products. In addition, product liability claims, injuries, defects, or other problems experienced by other companies in the battery industry could lead to unfavorable market conditions for the industry as a whole and may have an adverse effect on our ability to attract new customers, thus harming our growth and financial performance.

We are heavily dependent on third-party suppliers and contractors. Supply chain issues could adversely affect our operations and financial results.

We are heavily dependent on third-party suppliers and contractors and their ability to deliver sufficient quantities of key components, products and services at reasonable prices and in time for us to meet schedules for the delivery of our products and services. In addition, our operations depend on our ability to anticipate and our suppliers’ ability to fulfill, our needs for sufficient quantities of key components and products. Given the diverse distribution of our suppliers and contract manufacturers, and the long lead times required to manufacture, assemble and deliver our products, problems could arise in production, planning and inventory management and regulatory compliance that could seriously harm our business. Suppliers may face global supply chain challenges, such as transportation delays or reduced access to raw materials, and our business could be negatively impacted if suppliers are forced to reduce their normal operations.

If we elect to expand our production capacity by constructing one or more new manufacturing facilities, we may encounter challenges relating to the construction, management and operation of such facilities.

We currently operate our manufacturing facility located in Pennsylvania. We may, however, seek to construct one or more manufacturing facilities designed to meet our product supply needs in the future. Although we currently believe that we can expand our Turtle Creek facility to a 2 gigawatt-hour (“GWh”) manufacturing facility, we cannot provide any assurances that we would be able to successfully establish or operate a new manufacturing facility in a timely or profitable manner, or at all, or within any budget that might be forecasted for such a project. In addition, in order to access Tranche 3 and Tranche 4 under the DOE Loan Agreement, the Company would be required to open a new manufacturing facility satisfactory to the DOE to complete Lines 3 and 4 (as defined in the DOE Loan Agreement). The construction of any such facility would require significant capital expenditures and result in significantly increased fixed costs. If we are unable to transition manufacturing operations to any such new facilities in a cost-efficient and timely manner, then we may experience disruptions in operations, which could negatively impact our business and financial results. Further, if the demand for our products decreases or if we do not produce the expected output after any such new facility is operational, we may not be able to spread a significant amount of our fixed costs over the production volume, thereby increasing our product unit fixed cost, which would have a negative impact on our financial condition and results of operations.

Our ability to expand our manufacturing capacity would also greatly depend on our ability to hire, train and retain an adequate number of manufacturing employees, in particular employees with the appropriate level of knowledge, background and skills. Should we be unable to hire such employees, our business and financial results could be negatively impacted.

We could incur substantial costs as a result of violations of, or liabilities under, environmental laws.

Our properties, operations and the products we manufacture are subject to a number of environmental, health and safety laws and regulations in each of the jurisdictions in which we operate. These laws and regulations govern, among other things, air emissions, water discharges, handling and disposal of solid and hazardous substances and wastes, soil and groundwater contamination, employee health and safety and the content of products. Under certain of these laws and regulations, we may be subject to joint and several liability for environmental investigations and remediation, at our current or former sites or sites at which waste we generated was disposed, even if the contamination was not caused by us or was lawful at the time it occurred.Our failure to comply with these environmental, health and safety laws and regulations, including failing to obtain any necessary permits, could cause us to incur substantial civil or criminal fines or penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing our operations or requiring us to conduct or fund remedial or corrective measures, install pollution control equipment or perform other actions. The future identification of presently unidentified environmental conditions, more vigorous enforcement by regulatory agencies, enactment of more stringent laws, regulations or permit requirements, including relating to climate change, or other unanticipated events may arise in the future and give rise to environmental liabilities, which could adversely affect our business, financial condition and results of operations.

Increased scrutiny from stakeholders and regulators regarding environmental, social and governance practices and disclosures, including those related to climate change and sustainability, as well as recent U.S. based anti-ESG efforts, could result in additional costs and risks.

Companies across many industries are facing increasing scrutiny relating to their environmental, social and governance practices and disclosures. Our failure to satisfy evolving stakeholder expectations for ESG practices and reporting may potentially harm our reputation and impact employee retention, customer relationships and access to capital and financial markets.

Further, certain institutional investors, investor advocacy groups, investment funds, creditors, influential financial markets participants and other stakeholders have become increasingly focused on companies' ESG issues in evaluating their investments and business relationships. Certain organizations also provide ESG ratings, scores and benchmarking studies that assess companies’ ESG practices. Although there are no universally accepted standards for such ratings, scores or benchmarking studies, they are used by some investors to inform their investment and voting decisions. It is possible that our future shareholders or organizations that report on, rate or score ESG practices will not be satisfied with our ESG performance. At the same time, some stakeholders and regulators have increasingly expressed or pursued opposing views, legislation and investment expectations with respect to ESG, including the enactment or proposal of legislation or policies restricting, discouraging or otherwise regulating the consideration of ESG factors. Unfavorable press about or ratings or assessments of our ESG practices, regardless of whether or not we comply with applicable legal requirements, may lead to negative investor sentiment toward us, which could have a negative impact on our share price and our access to and cost of capital.

In addition, the adoption of new ESG-related regulations, or changes to existing ESG-related regulations, applicable to our business, or pressure from key stakeholders to comply with additional voluntary ESG-related initiatives or frameworks, could require us to make substantial investments in ESG matters, which could impact the results of our operations. Decisions or related investments in this regard could affect consumer perceptions as to our brand. We could also fail, or be perceived to fail, in our achievement of any announced ESG initiatives, goals or objectives, or we could be criticized for the scope of such initiatives, goals or objectives. If we fail to satisfy the expectations of investors and other key stakeholders or our initiatives, goals or objectives are not executed as planned, our reputation, financial results and market price of our common stock and access to and cost of capital could be materially and adversely affected.

Risks Related to Our Future Growth

If we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high levels of customer service, or adequately address competitive challenges.

We have experienced significant growth in recent periods and intend to continue to expand our business significantly within existing and new markets. This growth has placed, and any future growth may place, a significant strain on our management, operational and financial infrastructure. We will be required to expand, train and manage our growing employee base and scale and otherwise improve our IT infrastructure in tandem with that headcount growth. Our management will also be required to maintain and expand our relationships with customers, suppliers and other third parties and attract new customers and suppliers, as well as manage multiple geographic locations.

Our current and planned operations, personnel, customer support, IT, information systems and other systems and procedures might be inadequate to support future growth and may require us to make additional unanticipated investments in its infrastructure. Our success and ability to further scale our business will depend, in part, on our ability to manage these changes in a cost-effective and efficient manner. If we cannot manage our growth, we may be unable to take advantage of market opportunities, execute our business strategies, or respond to competitive pressures. This could also result in declines in quality or customer satisfaction, increased costs, difficulties in introducing new offerings, or other operational difficulties. Any failure to effectively manage growth could adversely impact our business and reputation.

Our growth prospects depend on our ability to capitalize on market opportunities.

We believe that several market opportunities could help fuel our growth prospects, including the following:

•the pervasiveness of electric grid congestion, creating an opportunity to deploy batteries to reduce the peak energy usage of a customer in specific locations where infrastructure constraints create a need for transmission and/or distribution upgrades;

•the demand for co-location of battery assets on solar or wind farms to store off-peak intermittent renewable energy production and provide on-peak energy at the higher price of alternative energy;

•C&I end users’ adoption of alternative energy generation technologies to supplement or replace on-the-grid energy usage; and

•the rapidly expanding data center market, where the surge in AI-driven workloads creates volatile, high-magnitude load swings that necessitates battery energy storage systems.

If these expected market opportunities do not materialize, or if we fail to capitalize on them, then we may not be able to meet our growth projections.

If we fail to meet the covenants in either the DOE Loan Facility or the Credit Agreement, we may be subject to default under the credit facilities, which could have a material adverse effect on our business.

The DOE Loan Facility and Credit Agreement contain various affirmative and negative covenants applicable to the Company including, among others, as defined in the Credit Agreement (i) meeting certain Minimum Consolidated EBITDA, Minimum Consolidated Revenue and Minimum Liquidity (the cash in accounts controlled by the collateral agent) measured quarterly, (ii) reporting and information covenants including the delivery of annual, quarterly and monthly financial statements, daily cash reports, annual financial plans and forecasts with weekly progress reports and updates, (iii) monthly meetings with the lenders and the engagement of advisors and consultants requested by the lenders, and (iv) restrictions on business and activities including debt incurrence, asset dispositions, distributions, investments and modifications to or terminations of various material contracts. The DOE Loan Facility and the Credit Agreement are subject to certain events of default which can be triggered by, among other things, (i) breach of payment obligations and other obligations and representations in the DOE Loan Facility, Credit Agreement or related documents, (ii) default under other debt facilities with a principal above a predetermined amount, (iii) failure to perform or comply with certain covenants in the DOE Loan Facility and the Credit Agreement, (iv) entry into a decree or order for relief in respect of the Company or any of its subsidiaries in an involuntary case under the Bankruptcy Code of the United States or under any other debtor relief law, (v) any money judgment, writ or warrant of attachment or similar process involving in the aggregate at any time an amount in excess of $2.5 million, (vi) any order, judgment or decree entered against the Company or the any of its subsidiaries decreeing the dissolution or split up of such entity, (vii) the failure of the common stock to be listed on an internationally recognized stock exchange in the United States and (viii) a change of control.

On November 26, 2024, the Company entered into the Credit Agreement Amendment, pursuant to which among other things, the applicability of the Minimum Consolidated Revenue and Minimum Consolidated EBITDA financial covenants were deferred until December 31, 2025 and certain provisions were modified to conform with comparable provisions in the DOE Loan Facility and with the terms of the Intercreditor Agreement. On May 28, 2025, the Company entered into the Limited Consent Agreement, pursuant to which among other things, the applicability of the Minimum Consolidated Revenue and Minimum Consolidated EBITDA financial covenants were deferred until March 31, 2027 and certain provisions were added to conform with comparable provisions in the Delayed Draw Term Loan. In the event the Company is unable to comply with all financial covenants when required under the Credit Agreement or the DOE Loan Facility, and the Company is unable to secure another waiver or amendment to the Credit Agreement or the DOE Loan Facility, the lenders may, at their discretion, exercise any and all of their existing rights and remedies, which may include, among other things, asserting their rights in the Company’s assets securing the loan, and the lender under the DOE Loan Facility may no longer be required to continue funding. There can be no assurance that the Company will be able to secure funding under the DOE Loan Facility or outside sources of capital in the event it fails to meet a funding condition or comply with the various covenants applicable to the Company and its subsidiaries under the DOE Loan Facility or the Credit Agreement. Moreover, the Company’s other lenders may exercise similar rights and remedies under the cross-default provisions of their respective borrowing arrangements with the Company. Any such default on the Credit Agreement or the DOE Loan Facility could have a material adverse effect on our business.

The Credit Agreement and the DOE Loan Facility are secured by a substantial portion of the assets of the Company and its subsidiaries, resulting in a lack of substantial remaining assets available for incurring additional indebtedness and requiring significant cash flow that the business may not be able to generate to service its substantial debt.

The Credit Agreement is guaranteed by certain subsidiaries of the Company and it is secured by perfected first priority security interests (subject to customary exceptions and permitted liens) over the assets of the Company and of its subsidiaries. In addition, the DOE Loan Facility is guaranteed by certain subsidiaries of the Company and is secured by a lien (subject to customary exceptions and permitted liens) on all real and personal property and all intellectual property collateral of the Company and its subsidiaries, including its Turtle Creek manufacturing site.

Because a substantial portion of the Company’s assets secure the Credit Agreement and the DOE Loan Facility, we do not have substantial remaining assets available to secure other indebtedness. Accordingly, we may not be able to incur additional secured indebtedness in the future. In addition, the terms of each of the Credit Agreement and the DOE Loan Facility significantly limit our ability to incur additional debt, including secured debt. If we are unable in the future to incur additional indebtedness, including secured indebtedness, to finance our operations and projects, such limitation could have an adverse effect on our business plans, financial condition and results of operations.

Moreover, our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including under the DOE Loan Facility, the Credit Agreement, the May 2025 Convertible Notes and the November 2025 Convertible Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In particular, unless and until we increase the number of authorized shares of our common stock, or otherwise increase the number of shares of our common stock available to settle conversions of the November 2025 Convertible Notes, and, in each case, reserve the required number of shares solely for issuance upon conversion of the November 2025 Convertible Notes, we will be required to settle all conversions of the November 2025 Convertible Notes entirely in cash. We may not have enough available cash or be able to obtain financing at the time we are required to pay any cash amounts due upon conversion of the November 2025 Convertible Notes.

The Company may need to seek alternative sources of capital, or risk its ability to continue operations, in the event it fails to meet a funding condition under the terms of the DOE Loan Facility or in the event that the government enacts laws and governmental regulations that could affect the availability of funding under the DOE Loan Facility.

Pursuant to the terms of the DOE Loan Facility, the lender is not required to provide funding under the DOE Loan Facility in the event that the Company does not meet the necessary funding conditions stipulated in the DOE Loan Facility. In the event the Company does not meet these funding conditions and the lender chooses not to continue funding, the Company would need to seek alternative sources of capital, which may not be available on acceptable terms or at all. If the lender does not continue funding, and the Company’s efforts to raise additional outside capital prove unsuccessful, management would be required to seek other strategic alternatives, which may include, among others, a significant curtailment in the Company’s operations, a sale of certain of the Company’s assets, a sale of the entire Company to strategic or financial investors and/or allowing the Company to become insolvent.

A substantial number of shares of the Company’s common stock that are issuable upon the exercise or conversion of securities issued under the Credit Agreement and the SPA are subject to a contractual lockup.

Under the terms of the Credit Agreement and the SPA, the holders of our securities issued hereunder are subject to a contractual lockup that expires on June 21, 2026. Such securities represent a substantial portion of our outstanding shares of common stock and, subject to beneficial ownership limitations, have the potential to represent an even larger portion of our outstanding shares of common Stock, and we are obligated to register the resale of these shares of common stock by the holders.

Upon the effectiveness of the resale registration statement or otherwise in accordance with Rule 144 under the Securities Act and after expiration or waiver of the lock-up, the holders may sell our common stock in the open market or in privately negotiated transactions, which could have the effect of increasing the volatility in the trading price of our common stock or putting significant downward pressure on the price of our common stock.

The resale, or expected or potential resale, of a substantial number of shares of our common stock in the public market could adversely affect the market price for our common stock and make it more difficult for you to sell your common stock at times and prices that you feel are appropriate. Furthermore, because there will be a large number of shares registered pursuant to the registration statement, selling holders could continue to offer the securities covered by the registration statement for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to a registration statement may continue for an extended period of time.

Further, sales of our common stock upon expected expiration of resale restrictions could encourage short sales by market participants. Generally, short selling means selling a security, contract or commodity not owned by the seller. The seller is committed to eventually purchase the financial instrument previously sold. Short sales are used to capitalize on an expected decline in the security’s price. As such, short sales of our common stock could have a tendency to depress the price of our common stock, which could further increase the potential for short sales.

We cannot predict the size of future issuances or sales of our common stock or the effect, if any, that future issuances and sales of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock, including issuances made in the ordinary course of the Company’s business, or the perception that such sales could occur, may materially and adversely affect prevailing market prices of our common stock.

Our planned expansion into new geographic markets or new product lines or services could subject us to additional business, financial and competitive risks.

During the years ended December 31, 2025 and 2024, we primarily sold our products in the United States. We have in the past, and may in the future, evaluate opportunities to expand into new geographic markets and introduce new product offerings and services that are a natural extension of our existing business. We also may from time to time engage in acquisitions of businesses or product lines with the potential to strengthen our market position, enable us to enter attractive markets, expand our technological capabilities, or provide synergy opportunities.

Our success operating in these new geographic or product markets, or in operating any acquired business, will depend on a number of factors, including our ability to develop solutions to address the requirements of the electric utility industry and C&I end users, our timely qualification and certification of new products, our ability to manage increased manufacturing capacity and production, and our ability to identify and integrate any acquired businesses.

Further, any additional markets that we may enter could have different characteristics from the markets in which we currently sell products, and our success will depend on our ability to adapt properly to these differences. These differences may include regulatory requirements, including tax laws, trade laws, labor regulations, tariffs, export quotas, customs duties, or other trade restrictions, limited or unfavorable intellectual property protection, international, political or economic conditions, restrictions on the repatriation of earnings, longer sales cycles, warranty expectations, product return policies and cost, performance and compatibility requirements. In addition, expanding into new geographic markets will increase our exposure to presently existing and new risks, such as fluctuations in the value of foreign currencies and difficulties and increased expenses in complying with United States and foreign laws, regulations and trade standards, including the Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”).

Failure to develop and introduce these new products successfully into the market, to successfully integrate acquired businesses or to otherwise manage the risks and challenges associated with our potential expansion into new product and geographic markets, could adversely affect our revenues and our ability to sustain profitability.

Our results of operations may fluctuate from quarter to quarter, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fall below expectations, resulting in a decline in the price of our common stock.

Revenue from our battery sales is primarily recorded upon transfer of ownership of the product to the customer. Under our customer contracts, this transfer typically takes place upon shipment of the battery from our manufacturing facility but, in some instances, occurs upon delivery to a customer site or, even more infrequently, when commercial operation commences. Because our revenues are generally derived from sales of hardware that may take many months to manufacture and prepare for delivery, such revenue can come in peaks and troughs based on the underlying customer arrangements. As a result, our quarterly results of operations are difficult to predict and may fluctuate significantly in the future based on the timing of product deliveries.

Risks Related to Our United States Operations

Some of our customers receive federal, state and local government incentives for renewable energy solutions. The reduction, elimination or expiration of government subsidies and economic incentives related to renewable energy solutions could reduce demand for our technologies and harm our business.

To promote renewable energy generation and consumption, federal, state, local and foreign government bodies provide incentives to owners, end users, distributors, system integrators and manufacturers of alternative energy systems in the form of rebates, tax credits and other financial incentives such as system performance payments, issuance of renewable energy credits associated with renewable energy generation and exclusion of certain renewable energy systems from property tax assessments. Some of our customers receive these incentives for investment in energy storage projects.

Our business relies, in part, on the co-location of battery assets with generation, including solar and wind technologies. The market for on-grid applications, where solar or wind power is used to supplement a customer’s electricity purchased from the utility network or sold to a utility under tariff, often depends in large part on the availability and size of government and economic incentives that vary by geographic market. The reduction, elimination or expiration of government subsidies and economic incentives for on-grid renewable electricity, or the implementation of operational mandates for fossil fuels, such as the December 2025 “Must-Run” Emergency Orders issued by the Department of Energy requiring coal-fired power plant facilities scheduled for retirement to continue generating power, may negatively affect the competitiveness of alternative electricity generation relative to conventional and nonrenewable sources of electricity and could harm or halt the growth of the alternative electricity industries. Because our C&I end user sales are generally expected to be made into the on-grid market, these changes could harm our business. For example, the IRA allows owners of new batteries to claim an ITC of 6%, which can increase to 30% if certain wage and apprenticeship standards are met, and to 70% depending on the location of the battery system and amount of domestic content. The credit is available for battery systems put into service during 2023 through a period that extends at least into 2033 (and possibly longer). Although the OBBBA maintains the ITC for energy storage systems, it generally extends the restrictions relating to PFEs described above under "Item 1. Business—Regulations--Governmental Programs and Incentives--One Big Beautiful Bill Act" to the availability of the tax credit.

The IRA also allows manufacturers of certain battery components made in the United States to claim tax credits. Under Internal Revenue Code Section 6417(d), certain eligible taxpayers, including such manufacturers, can elect direct payment, enabling the Internal Revenue Service to treat the tax credit amount as a deemed tax payment and refund any excess as a cash tax payment, even if the taxpayer has no tax liability. This election can be made for any taxable year in which the taxpayer qualifies for the credit, and, once made, applies to that taxable year and the subsequent four taxable years, resulting in five consecutive years of direct payment. The tax credits for manufacturers start phasing down in amount after 2029 and end after 2032. The PFE restrictions introduced under the OBBBA generally apply to this tax credit program as well.

Uncertainty relating to the interpretation and implementation of federal renewable energy tax credits has in the past caused certain customers to take an extended period to evaluate, negotiate, and enter energy storage arrangements, which has impacted our business and results of operations. Current uncertainty related to changes imposed by the OBBBA may in the future similarly cause customers to delay contracting decisions or may cause customers to delay or cancel existing projects as they navigate such uncertainty. In addition, these federal renewable energy tax credit programs may be subject to future changes, restrictions, or repeal. Any such developments could have an adverse

impact on our business, financial condition, and results of operations, which could have a material negative effect on our business and results of operations.

The full impact of the modifications to the tax credits and PFE restrictions in the OBBBA, its accompanying guidance, and potential changes in law that may apply to our business and operations as well as our customers’ and suppliers’ businesses cannot be known with certainty and we may not recognize the full extent of benefits we currently anticipate, which may materially and adversely impact our business, financial condition, and results of operations. We are continuing to evaluate the potential overall impact and applicability of these tax credits, as modified by the OBBBA, and any potential future changes in law on our business and operations.

In general, subsidies and incentives may expire on a particular date, end when the allocated funding is exhausted or be reduced or terminated as renewable energy adoption rates increase or as a result of legal challenges, the adoption of new statutes or regulations or the passage of time. These reductions or terminations often occur without warning.

In addition, several jurisdictions have adopted renewable portfolio standards, which mandate that a certain portion of electricity delivered by utilities to customers each year must come from renewable energy resources. Utilities must either generate the renewable electricity themselves or buy renewable energy credits ("REC"s) from independent generators who have been awarded them for generating renewable electricity. Utilities may buy such RECs bundled with renewable electricity. A REC allows the utility to add this electricity to its renewable portfolio requirement total without actually expending the capital for generating facilities. However, there can be no assurances that such policies will continue or will not be subject to changes.

If subsidies and incentives applicable to alternative energy implementation or usage are reduced or eliminated, or the regulatory landscape otherwise becomes less favorable, then there could be reduced demand for alternative energy solutions, which could have an adverse impact on our business, financial condition, and results of operations. The current presidential administration and Congress may seek to repeal or curtail existing federal renewable energy tax credits, as well as other policies intended to incentivize or favor renewable energy technologies. Changes in laws related to federal renewable energy tax credits under the IRA or the OBBBA, or changes in interpretations of such laws, communications with regulatory agencies, transactions or agreements with third parties, and/or evolving interpretations of regulations may result in a material change in our estimate of tax credits to which we may be entitled, which could materially affect our business, financial position and results of operations. Finally, the Supreme Court’s recent decision in Loper Bright Enterprises v. Raimondo, which restricted federal agencies’ ability to interpret vague or broad legislation, could introduce uncertainty around applicable agency regulations and, therefore, negatively impact the demand for our products or services. See Part I, Item 1 - Business - Regulations - Governmental Programs and Incentives for further discussion of government programs and incentives.

We have operations in the United States, which exposes us to multiple federal, state and local regulations. Changes in applicable law, regulations or requirements, or our material failure to comply with any of them, can increase our costs and have other negative impacts on our business.

Applicable laws and requirements address multiple aspects of our operations, such as worker safety, consumer rights, data privacy, cybersecurity, employee benefits and more, and can often have different requirements in different jurisdictions. Changes in these requirements, or any material failure to comply with them, could increase our costs, affect our reputation, limit our business, drain management’s time and attention or otherwise, generally impact our operations in adverse ways.

We are subject to complex and evolving laws, regulations, rules, standards and contractual obligations regarding data privacy and cybersecurity, which could increase the cost of doing business, compliance risks and potential liability.

We are subject to complex and evolving laws, regulations, rules, standards and contractual obligations governing data privacy and cybersecurity and any failure to comply with these laws, regulations, rules, standards and contractual obligations could expose us to liability and/or reputational damage. Compliance with these laws, regulations, rules and standards may require us to change our policies, procedures, products and technology for data privacy and cybersecurity, which could, among other things, make us more vulnerable to operational failures and to monetary penalties for breach of such laws, regulations, rules and standards.

In the U.S., there are numerous federal, state and local data privacy and cybersecurity laws and regulations governing the collection, sharing, use, retention, disclosure, security, storage, transfer and other processing of personal information. At the federal level, we are subject to, among other laws and regulations, the rules and regulations promulgated under the authority of the Federal Trade Commission (which has the authority to regulate and enforce against unfair or deceptive acts or practices in or affecting commerce, including acts and practices with respect to data privacy and cybersecurity). Moreover, the U.S. Congress has recently considered, and is currently considering, various proposals for more comprehensive data privacy and cybersecurity legislation, to which we may be subject if passed. At the U.S. state level, we may be subject to laws and regulations such as the California Consumer Privacy Act as amended by the California Privacy Rights Act (collectively, the “CCPA”), which broadly defines personal information and gives California residents expanded privacy rights and protections, such as affording them the right to access and request deletion of their information and to opt out of certain sharing and sales of personal information. Numerous other states also have enacted, or are in the process of enacting or considering, comprehensive state-level data privacy and cybersecurity laws and regulations that share similarities with the CCPA. Moreover, laws in all 50 U.S. states require businesses to provide notice under certain circumstances to consumers whose personal information has been disclosed as a result of a data breach.

Further, while we strive to publish and prominently display privacy policies that are accurate, comprehensive and compliant with applicable laws, regulations, rules and industry standards, we cannot ensure that our privacy policies and other statements regarding our practices will be sufficient to protect us from claims, proceedings, liability or adverse publicity relating to data privacy and cybersecurity. Although we endeavor to comply with our privacy policies, we may at times fail to do so or be alleged to have failed to do so. The publication of our privacy policies and other documentation that provide promises and assurances about data privacy and cybersecurity can subject us to potential government or legal action if they are found to be deceptive, unfair, or misrepresentative of our actual practices. Any concerns about our data privacy and cybersecurity practices, even if unfounded, could damage our reputation and adversely affect our business.

Any failure or perceived failure by us to comply with our privacy policies, or applicable data privacy and cybersecurity laws, regulations, rules, standards or contractual obligations, or any compromise of security that results in unauthorized access to, or unauthorized loss, destruction, use, modification, acquisition, disclosure, release or transfer of personal information, may result in requirements to modify or cease certain operations or practices, the expenditure of substantial costs, time and other resources, proceedings or actions against us, legal liability, governmental investigations, enforcement actions, claims, fines, judgments, awards, penalties, sanctions and costly litigation (including class actions). Any of the foregoing could harm our reputation, distract our management and technical personnel, increase our costs of doing business, adversely affect the demand for our products and services and ultimately result in the imposition of liability, any of which could have a material adverse effect on our business, financial condition and results of operations.

Changes in tax laws or tax rulings could materially affect our business, financial position and results of operations.

The tax regimes to which we are subject or under which we operate are unsettled and may be subject to significant change. Changes in tax laws or tax rulings, or changes in interpretations of existing laws, could materially affect our business, financial position and results of operations. For instance, we expect a material portion of our produced batteries and battery cells will qualify for production tax credits under Section 45X of the IRA. For more information, see Part I, Item 1—Business—Regulations—Governmental Programs and Incentives—Inflation Reduction Act of 2022. The IRA contains production tax credits for certain battery cells and battery modules. The Company's ability to benefit from Section 45X production tax credits is not guaranteed and is dependent upon the federal government's ongoing implementation, guidance, regulations, and/or rulemakings. We closely monitor tax developments in the countries where we operate. We regularly assess the likely outcomes of our tax audits and disputes to determine the appropriateness of our tax reserves. However, any tax authority could take a position on tax treatment that is contrary to our expectations, which could result in tax liabilities in excess of reserves

We could be adversely affected by any violations of the FCPA, the U.K. Bribery Act and other foreign anti-bribery laws, as well as violations against export controls and economic embargo regulations.

The FCPA prohibits companies and their intermediaries from making improper payments to foreign government officials for the purpose of obtaining or retaining business. Other countries in which we operate also have anti-bribery laws, some of which prohibit improper payments to government and non-government persons and entities. Our policies mandate compliance with these anti-bribery laws. However, we currently operate in and intend to further expand into, many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. In addition, due to the level of regulation in our industry and related energy industries, our entry into certain jurisdictions may require substantial government contact where norms can differ from U.S. standards. Although we expect to maintain strict internal control policies and procedures designed to guard against improper conduct, there can be no guarantee that our employees, agents and business partners will not take actions in violation of our internal control policies. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable laws, including anti-corruption laws, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, and detecting, investigating and resolving actual or alleged violations can be expensive and require significant time and attention from senior management. Any violation of U.S. federal and state and non-U.S. laws, regulations and policies could result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in the United States or other applicable jurisdictions. In addition, actual or alleged violations could damage our reputation and ability to do business. Any of the foregoing could materially adversely affect our business, financial condition and results of operations.

Furthermore, we are subject to the export controls and economic embargo rules and regulations of the United States, including, but not limited to, the Export Administration Regulations and trade sanctions against embargoed countries, which are administered by the Office of Foreign Assets Control within the Department of the Treasury, as well as the laws and regulations administered by the Department of Commerce. These regulations limit our ability to market, sell, distribute or otherwise transfer our products or technology to prohibited countries or persons. While we do not conduct business with sanctioned and embargoed countries and we expect to maintain strict internal controls policies and procedures designed to guard against improper conduct, a determination that we have failed to comply, whether knowingly or inadvertently, may result in substantial penalties, including fines and enforcement actions and civil and/or criminal sanctions, the disgorgement of profits and the imposition of a court-appointed monitor, as well as the denial of export privileges, and may have an adverse effect on our reputation.

Risks Related to Intellectual Property

If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, then our business and results of operations could be materially harmed.

Our success depends to a significant degree on our ability to protect our intellectual property and other proprietary rights. We rely on a combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as confidentiality and other contractual provisions with our customers, suppliers, employees and others, to establish and protect our intellectual property and other proprietary rights. Our ability to enforce these rights is subject to general litigation risks, as well as uncertainty as to the enforceability of our intellectual property rights in various countries. When we seek to enforce our rights, we may be subject to claims that our intellectual property rights are invalid or not enforceable. Our assertion of intellectual property rights may result in another party seeking to assert claims against us, which could harm our business. Our inability to enforce intellectual property rights under any of these circumstances would likely harm our competitive position and business.

We have been issued patents in, or have patent applications pending in the United States, North America, Europe, South America, Asia and Australia. We cannot guarantee that any of our pending applications will be approved or that our existing and future intellectual property rights will be sufficiently broad to protect our proprietary technology, and any failure to obtain such approvals or finding that our intellectual property rights are invalid or unenforceable could force us to, among other things, rebrand or redesign our affected products. In countries where we have not applied for patent protection or where effective intellectual property protection is not available to the same extent as in the United States, we may be at greater risk that our proprietary rights will be infringed, misappropriated or otherwise violated.

Our intellectual property may be stolen or infringed, misappropriated or otherwise violated. Despite our implementation of security measures, our IT systems and those of our service providers are vulnerable to circumstances beyond our reasonable control which may lead to the theft of our intellectual property or trade secrets or business disruption, including inappropriate retention or disclosure of trade secrets by current or former employees. To the extent that any disruption or security breach results in a loss or damage to our data or an inappropriate disclosure of confidential information, it could cause significant damage to our reputation, affect our relationships with our customers, suppliers and employees and lead to claims against the company. Any lawsuits that we may initiate to protect our significant investment in our intellectual property also may consume management and financial resources for long periods of time and may not result in favorable outcomes, which may adversely affect our business, results of operations or financial condition.

Third parties may assert that we are infringing, misappropriating or otherwise violating their intellectual property rights, which could divert management’s attention, cause us to incur significant costs and prevent us from selling or using the technology to which such rights relate.

Our competitors and other third parties hold numerous patents related to technology used in our industry. From time to time, we may be subject to claims of intellectual property infringement, misappropriation or other violation and related litigation, and, if we gain greater recognition in the market, we will face a higher risk of being the subject of claims that we have violated others’ intellectual property rights. While we believe that our products, technology and brands do not infringe, misappropriate or otherwise violate in any material respect upon any valid intellectual property rights of third parties, we cannot be certain that we would be successful in defending against any such claims. If we do not successfully defend or settle intellectual property claims, we could be liable for significant monetary damages and could be prohibited from continuing to use certain technology, business methods, content, or brands. To avoid a prohibition, we could seek a license from the applicable third party, which could require us to pay significant royalties, increasing our operating expenses. If a license is not available at all or not available on reasonable terms, then we may be required to develop or license a non-violating alternative, either of which could require significant effort and expense. If we cannot license or develop a non-violating alternative, we would be forced to limit or stop sales of our offerings and may be unable to effectively compete. Any of these results would adversely affect our business, financial condition and results of operations.

Risks Related to Our Securities

Under the terms of the Credit Agreement, the SPA and the securities issued thereunder, current stockholders may be subject to significant dilution and the voting power of the currently outstanding common stock could be significantly diluted.

As of February 24, 2026, there were 339,434,259 shares of common stock issued and outstanding and an aggregate of 218,541,252 shares of common stock issuable upon the conversion or exercise of outstanding convertible securities (as calculated under the Credit Agreement and the SPA), including 159,587,654 shares of common stock underlying the Warrant (as defined below) and Preferred Stock (as defined below) issued to Cerberus under the Credit Agreement and the SPA (the “Cerberus Securities”).

The Certificates of Designation governing the Series B Preferred Stock (the “Series B Certificates of Designation”) contain preemptive rights that permit the holders of Series B Preferred Stock to participate in certain future equity offerings by the Company.

In addition, if the Company were to issue additional shares of common stock or securities convertible or exercisable into common stock or trigger anti-dilution protection under the Cerberus Securities, the Cerberus Securities may become convertible or exercisable into additional shares of common stock. The issuance, pursuant to the terms of the Cerberus Securities, of common stock will dilute the percentage ownership interest of all stockholders, could dilute the book value per share of the common stock and will increase the number of the Company’s outstanding shares, and upon conversion or exercise would dilute the voting power of the common stock, which could cause the market price of our common stock to decrease. Depressed trading prices of our common stock could further impair our ability to raise sufficient capital to carry on our business.

We currently have a significant number of outstanding securities that are exercisable for or convertible into our common stock, which could result in significant additional dilution and downward pressure on our stock price. Future issuances of our common stock, including common stock that may be issuable pursuant to outstanding warrants or other convertible securities, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

In addition to the Cerberus Securities, the Company has issued the May 2025 Convertible Notes, November 2025 Convertible Notes, DOE Warrants and warrants issued pursuant to the April, May and December 2023 offerings, which are each exercisable for or convertible into common stock at certain exercise or conversion prices per share. See Note 13, Borrowings and Note 14, Warrants Liability for further discussion. The issuance of shares of common stock upon exercise or conversion of our warrants or convertible securities would result in significant additional dilution to our current stockholders, which could adversely affect the price of our common stock and the terms on which we could raise additional capital. If we sell additional shares of common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges senior to the holders of our common stock.

To the extent that any shares of common stock are issued upon exercise or conversion of any of these securities, there will be an increase in the number of shares of common stock eligible for resale in the public market. Sales of a substantial number of such shares in the public market could adversely affect the market price of our common stock.

Provisions in our Charter and Delaware law may have the effect of discouraging lawsuits against our directors and officers.
