Eos Energy Enterprises (EOSE) Risk Analysis

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
