Risks Related to our Business and Industry

We have a history of losses and have to deliver significant business growth to achieve sustained, long-term profitability and long-term commercial success.

We had net losses on a GAAP basis in each fiscal quarter since our inception. For the two-year period ended December 31, 2019 and for the nine-month period ended September 30, 2020, we had $28.5 million, $79.5 million and $45.3 million in net losses, respectively. In order 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, grow demand for our products, and seize new market opportunities by leveraging our proprietary technology and our manufacturing processes for novel solutions. Failure to do one or more of these things could prevent us from achieving sustained, long-term profitability.

As we transition from our research and development and our system pilot phase and into a full commercial phase, we expect, based on our sales pipeline, to grow revenues. However, our revenue 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. If we are not able to sustain revenue growth and raise the capital necessary to support our operations, we may be unable to continue as a going concern.

We identified material weaknesses in our internal control over financial reporting at December 31, 2019 and 2018, and we may identify additional material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements of our financial statements. If we fail to remediate any material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, our ability to accurately and timely report our financial results could be adversely affected.

As a public company, we are required to comply with the SEC’s rules implementing Sections 302 and 404 of the Sarbanes-Oxley Act, which requires management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of controls over financial reporting. Though we are required to disclose changes made in our internal controls and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal control over financial reporting pursuant to Section 404 until the year following our first annual report required to be filed with the SEC. However, as an emerging growth company, our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 until the later of the year following our first annual report required to be filed with the SEC and the annual revenues are $100 million or greater, or the date we no longer are an emerging growth company. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not effective.

Notwithstanding the foregoing, in connection with the audits of our financial statements for the years ended December 31, 2019 and 2018, we and our auditors identified certain control deficiencies in the design and operation of our internal control over financial reporting that constituted material weaknesses. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis.

The material weaknesses resulted from our lack of (i) a formalized internal control framework, (ii) segregation of duties in the financial reporting process, (iii) review and approval of journal entries, and (iv) management review controls. These remain material weaknesses as of the date of this prospectus. In order to remediate these material weakness, we plan to hire additional personnel. In addition, we have implemented, and plan to continue to implement, new controls, new processes and technologies to implement formalized internal controls framework and procedures. We cannot provide any assurances that the measures that we have taken to remediate, and that will take to remediate, these material weaknesses will be sufficient to prevent future material weaknesses from occurring. We also cannot assure you that we have identified all of our existing material weaknesses.

In light of the control deficiencies and the resulting material weaknesses that were identified, we believe that it is possible that, had we and our registered public accounting firm performed an assessment or audit, respectively, of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act, additional material weaknesses may have been identified.

When evaluating our internal control over financial reporting, we may identify material weaknesses that we may not be able to remediate in time to meet the applicable deadline for compliance with the requirements of Section 404. If we are unable to remediate our existing material weaknesses or identify additional material weaknesses and are unable to comply with the requirements of Section 404 in a timely manner or assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting once we are no longer an emerging growth company, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common stock could be negatively affected, and we could become subject to investigations by the stock exchange on which our securities are listed, the SEC or other regulatory authorities, which could require additional financial and management resources.

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

Since our inception, we sold only ten (10) Eos Znyth^® DC battery systems to our customers. We began commercializing our products as recently as 2018, and while our research and development activities successfully established the efficacy of our chemistry, we struggled to incorporate our proven technologies into an effective manufacturing design. Although the relatively long research and development runway has given us the time to refine our designs and optimize our technologies, the latest generation of our products have been brought to market only recently.

Our success will depend on our ability to manufacture products at scale 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. 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 future prospects.

If demand for low-cost energy storage solutions does not continue to grow or grows at a slower rate than we anticipate, our business and results of operations may be impacted.

Our flagship product, the Eos Znyth^® system, is a Znyth^® battery that can be used as an alternative to lithium-ion (“Li-ion”) batteries. Our products are being piloted by eight blue chip utilities and commercial and industrial (“C&I”) end users. The pilots are being used on several use cases including, solar shifting, peak shaving, price arbitrage, utility ancillary services and microgrids. We cannot provide any assurances that utilities or C&I users will adopt our products as alternative energy storage solutions at levels sufficient to grow our business.

The viability and demand for our products, may be affected by many factors outside of our control, including:

If we do not manage these risks and overcome these potential difficulties outside of our control successfully, our business and results of operations may suffer.

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 components, full recyclability at end-of-life, a fifteen (15) to thirty (30) year product life requiring minimal maintenance, and a wide thermal operating range that eliminates the need for the fire suppression and heating, ventilation and air conditioning equipment (“HVAC”), which would otherwise be required for use with Li-ion batteries.

However, if our manufacturing costs increase, or if our expectations regarding the operation, performance, maintenance and disposal of our products are not realized, then we could have difficulty marketing our products as a superior alterative to already-established technologies and impact the market reputation and adoptability of our products. In addition, 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.

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 our revenues will grow 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.

The loss of one or more members of our senior management team or other key personnel or our failure to attract additional qualified personnel may adversely affect our business and our ability to achieve our anticipated level of growth.

We depend on the continued services of our senior management team, including our chief executive officer, chief strategy officer and chief financial officer, and other key personnel, each of whom would be difficult to replace. 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.

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.

Third parties might attempt to gain unauthorized access to our network or seek to compromise our products and services.

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

From time to time, we encounter intrusions or attempts at gaining unauthorized access to our network and we routinely run intrusion checks. To date, none has 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 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. In addition to intentional third-party cyber-security breaches, the integrity and confidentiality of company and customer data may be compromised as a result of human error, product defects, or technological failures. Cybersecurity breaches, whether successful or unsuccessful, and other IT system interruptions, including those resulting from human error and technological failures, could result in our 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.

The failure or breach of our IT systems could affect our sales and operations.

Our email and collaboration tools are outsourced to a managed services provider, Delval Technology Solutions (“DTS”). While we regularly review the cyber security tools and other security protection provided by DTS and DTS 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. We operate a number of IT systems throughout our business that could fail for a variety of reasons, including the threats of unauthorized intrusions and attackers. 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, cyber-security breaches could potentially lead to the unauthorized release of sensitive, confidential or personal data or information, improper use of our systems, or, unauthorized access, use, disclosure, modification or destruction of information or defective products. If these cyber-security 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 cyber-security problems, we could face significant unplanned capital investments and any damage or interruption could have a material adverse effect on our reputation, business, financial condition, and results of operations.

We may not be able to identify or complete transactions with attractive acquisition candidates. Future acquisitions may result in significant transaction expenses and we may incur significant costs. We may experience integration and consolidation risks associated with these future acquisitions.

We may from time to time selectively pursue on an opportunistic basis acquisitions of additional businesses that complement our existing business and footprint. The success of any such growth strategy would depend, in part, on selecting strategic acquisition candidates at attractive prices and effectively integrating their businesses into our own, including with respect to financial reporting and regulatory matters. There can be no assurance that we will be able to identify attractive acquisition candidates or complete the acquisition of any identified candidates at favorable prices and upon advantageous terms and conditions, including financing alternatives.

We may not have sufficient management, financial and other resources to integrate and consolidate any future acquisitions. Any significant diversion of management’s attention or any major difficulties encountered in the integration of the businesses we acquire could have a material adverse effect on our business, financial condition or results of operations, which could decrease our profitability and make it more difficult for us to grow our business. Among other things, these integration risks could include:

In addition, general economic conditions or unfavorable capital and credit markets could affect the timing and extent to which we can successfully acquire or integrate new businesses, which could limit our revenues and profitability.

We are exposed to various risks related to legal proceedings or claims that could adversely affect our operating results. The nature of our business exposes us to various liability claims, which may exceed the level of our insurance coverage resulting in our not being fully protected.

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 we could incur substantial monetary liability and/or be required to change our business practices.

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.

A current stockholder has made certain allegations questioning the propriety of certain historical convertible debt issuances by us. While we believe that these allegations or any additional claims that may be asserted by such stockholder in connection with the approval of historical transactions or otherwise would be without merit, the results of any potential legal proceedings related to such claims would be difficult to predict. Whether or not the stockholder’s claim is successful, any litigation itself could be time consuming and expensive, and could divert the attention of our management away from their regular business. While the former EES LLC unit holders are required to indemnify us and certain others for, and pledge 40% of the portion of the merger consideration delivered to them in exchange for their units in connection with, any losses arising out of the above-referenced allegations (subject to the terms and conditions set forth in the Merger Agreement), there is no guarantee that we will successfully collect sufficient amounts in connection with an indemnification claim or realize sufficient value from the pledged shares to cover the cost of any lawsuit commenced in connection therewith. If any potential lawsuit is adversely resolved against us or our board of directors, it could have a material adverse effect on our business, financial condition, and results of operations.

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.

We have approximately sixty-six (66) full time employees and one part-time employee as of September 30, 2020, none of whom are represented by unions or covered by collective bargaining agreements. If a union sought to organize any of our employees, such organizing efforts or collective bargaining negotiations could potentially lead to work stoppages and/or slowdowns or strikes by certain of our employees, which could adversely affect our ability to serve our customers. Further, settlement of actual or threatened labor disputes or an increase in the number of our employees covered by collective bargaining agreements can have unknown effects on our labor costs, productivity and flexibility.

Risks Related to our Products and Manufacturing

We must obtain environmental, health and safety certifications for Gen 2.3 product.

While our engineering is working closely with the Underwriters Laboratories (“UL”) and Technischer Überwachungsverein (“TüV”) certification agencies to certify our Gen 2.3 product against all applicable safety standards, there is no guarantee that such certification shall be obtained. From this certification, we also intend to expand our Gen 2.3 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”). 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.

Compared to traditional energy storage technologies, our products have less power density and efficient power and may be considered inferior to competitors’ products.

Traditional Li-ion batteries offer higher power density and a slower self-discharge rate than our batteries. If customers were to place greater value on power density and efficient power delivery over the numerous other advantages of our technologies, including the widely-available and low-cost materials with no rare earth components, full recyclability at end-of-life, a fifteen (15) to thirty (30) year product life requiring minimal maintenance, and a wide thermal operating range that eliminates the need for the fire suppression and heating, then we could have difficulty positioning our batteries as a viable alternative to traditional Li-ion batteries and our business would suffer.

We rely on ours contract manufacturers and their respective business practices to manufacture our products.

On August 21, 2019, we entered into a joint venture agreement with Holtec International (“Holtec”) and formed HI-POWER, LLC (“HI-POWER”), which is owned 51% by Holtec and 49% by us. While we are free to either establish our own manufacturing capability, form a joint venture with another party, or hire a contract manufacturing partner to manufacture batteries and products delivered outside of North America, HI-POWER has exclusive rights to manufacture batteries sold and delivered in North America by us, provided that HI-POWER meets cost, quality and delivery “performance metrics” as defined by HI-POWER’s board of directors and the applicable joint venture arrangements between Holtec and us. HI-POWER’s board of directors is comprised of two members designated by Holtec and two members designated by us. Actions of the board must generally be approved by a majority of the directors, except for certain actions that require unanimous approval.

We rely on the HI-POWER’s board of directors’ oversight to ensure that HI-POWER follows ethical business practices such as fair wage practices and compliance with environmental, safety, and other local laws. A lack of demonstrated compliance could lead us to seek alternative manufacturers, which could increase our costs and result in delayed delivery of our products, product shortages, or other disruptions of our operations. Violation of labor or other laws by HI-POWER or the divergence of a manufacturer’s labor or other practices from those generally accepted as ethical in the United States or other markets in which we do business could also attract negative publicity for us and harm our business.

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

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, modifies 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, increased 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.

The ongoing COVID-19 pandemic has caused significant uncertainty in the United States and global economies as well as the markets we serve and could adversely affect our business, results of operations and financial condition.

The COVID-19 pandemic continues to spread throughout the United States and in various parts of the world and has resulted in authorities implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. We remain unable to accurately predict the full impact that COVID-19 will have on our results of operations, financial condition, liquidity and cash flows due to numerous uncertainties, including the duration and severity of the pandemic and containment measures. Our compliance with containment and mitigation measures has not yet materially impacted our day-to-day operations, but there can be no guaranty that the pandemic will not disrupt our business and operations or impair our ability to implement our business plan successfully.

To support the health and well-being of our employees, customers, partners and communities, since approximately March 19, 2020 all of our non-essential employees have been working remotely. This represents approximately 74% of our workforce. In addition, we understand that the employees of many of our customers are working remotely, which may delay the timing of some orders as well as shipments and cash collections. There can be no guaranty that disruptions, such as staff not being allowed to enter our manufacturing facility or our supply chain being disrupted, to our operations caused by COVID-19 will not result in inefficiencies, delays and additional costs in our product development, sales, marketing, and customer service efforts that we cannot fully mitigate through remote or other alternative work arrangements. For example, COVID-19 caused a several week delay in completing the UL certification of the Gen 2.3 product due to the certification company being delayed in completing the in-person witness tests.

More generally, the pandemic raises the possibility of an extended global economic downturn and has caused volatility in financial markets, which could affect demand for our products and services and impact our results and financial condition even after the pandemic is contained and the shelter-in-place orders are lifted. For example, Eos may be unable to collect receivables from those customers significantly impacted by COVID-19. Also, a decrease in orders in a given period could negatively affect our revenues in future periods, particularly if experienced on a sustained basis. The pandemic may also have the effect of heightening many of the other risks described in these “Risk Factors”, particularly those risks associated with our customers and supply chain.

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

We rely on a single-source joint venture manufacturer. As a result, a sustained or repeated interruption in the manufacturing of our products by HI-POWER due to labor shortage, fire, flood, war, pandemic or natural disasters may interfere with our ability to manufacture our products and fulfil 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. The current “Gen 2.3” battery design after years of research and prototype development has resulted in robust control of cell-to-cell spacing using a method which can easily be scaled for mass manufacturing at low cost.

Although our latest “Gen 2.3” products meet stringent quality requirements, they 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 or components or manufacturing difficulties, which can affect the quality of our products. Any actual or perceived errors, 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, 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. HI-POWER provides us with a two (2) year manufacturing warranty, which we pass to our customers based on the use case of the customer and normal system degradation expected from such use case. We also offer customers an extended performance warranty of up to twenty (20) 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 wishes to ensure. 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.

We, in turn, provide a two (2) year design warranty to HI-POWER, which warrants that the DC battery design will be free of design defects for the two-year warranty period. As a result, we effectively bear the risk of design warranty claims for two (2) years after we or Holtec has sold any products manufactured by HI-POWER (or much longer, in the case of any extended performance warranty purchased by our customers). We also bear the full risk of any manufacturing warranty claims under its extended warranty after the initial two (2) year period covered by HI-POWER has expired. 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, including as 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.

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

HI-POWER would maintain its exclusive rights to manufacture the batteries for our products sold and delivered in North America if it continues to meet the quality, cost and delivery timelines set by its board of directors and as further specified in the applicable joint venture arrangements between us and Holtec. However, if HI-POWER fails to meet these required performance metrics, then we would be free to establish our own manufacturing operations for North America, either directly or through other partnerships. Under these circumstances, we would have the right to transfer manufacturing processes, technology and know-how from HI-POWER to any such new facility. In addition, for sales outside of North America, we are free to establish our own manufacturing facilities or to partner with other companies to manufacture its products.

Accordingly, we may, in the future, seek to construct one or more manufacturing facilities designed to meet our product supply needs. Although we currently believe that we could build a new one (1) gigawatt-hour (“GWh”) manufacturing facility in less than eight months, we cannot provide any assurances that we would be able to successfully establish or operate our manufacturing facility in a timely or profitable manner, or at all, or within any budget that might be forecasted for such a project. 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 per product 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.

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. In particular, we will be required to expand, train, and manage our growing employee base and scale and otherwise improve our information technology (“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 investment in our 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, then 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 a number of market opportunities could help fuel our growth prospects, including the following:

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.

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

In the years ended December 31, 2019 and 2018, we sold our products in a number of different countries, including the United States, India and the United Kingdom. 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, at the time of commercial operation. 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.

Forecasts of market growth in this prospectus may not be accurate.

Market opportunity estimates and growth forecasts included in this prospectus are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The forecasts and estimates in this prospectus relating to the expected size and growth of the markets for energy storage and other markets in which we participate may prove to be inaccurate. Even if these markets experience the forecasted growth described in this prospectus, we may not grow our business at similar rates, or at all. Our future growth is subject to many factors, including market adoption of our products, which is subject to many risks and uncertainties. Accordingly, the forecasts and estimates of market size and growth described in this prospectus, should not be taken as indicative of our future growth. In addition, these forecasts do not take into account the impact of the current global COVID-19 pandemic, and we cannot assure you that these forecasts will not be materially and adversely affected as a result.

Risks Related to our United States and Foreign Operations

We could be adversely affected by any violations of the FCPA, the U.K. Bribery Act, and other foreign anti-bribery laws.

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 guaranty 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.

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, payments of renewable energy credits associated with renewable energy generation and exclusion of certain renewable energy systems from property tax assessments.

Our business relies, in part, on the co-location of battery assets with 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 solar electricity may negatively affect the competitiveness of alternative electricity generation relative to conventional and non-solar renewable 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, in 2015 the U.S Congress passed a multi-year extension to the solar Investment Tax Credit (“ITC”), which extension helped grow the U.S solar market. As of January 1, 2020, the ITC is being gradually reduced from thirty percent (30%) to twenty-six percent (26%) for both residential and commercial in 2020 and is expected to reach ten percent (10%) for commercial only in 2022. The reduction in the ITC could reduce the demand for solar energy solutions in the United States, which would have an adverse impact on our business, financial condition, and results of 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 solar 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 come from a set of eligible renewable energy resources by a certain compliance date. Some programs further specify that a portion of the renewable energy quota must be from solar electricity. Under some programs, a utility can receive a “credit” for renewable energy produced by a third party by either purchasing the electricity directly from the producer or paying a fee to obtain the right to renewable energy generated but used by the generator or sold to another party. A renewable energy credit 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. For example, in December 2015, Nevada’s Public Utilities Commission increased the fixed service charge for net-metered solar customers and lowered compensation for net excess solar generation proposals to extend compliance deadlines, reduce targets or repeal standards have also been introduced in a number of states.

If the foregoing or any other 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.

Changes in the U.S. trade environment, including the recent imposition of import tariffs, could adversely affect the amount or timing of our revenues, results of operations or cash flows.

We currently procure the felt required for our batteries and the electrical cables for the battery container from China, as we believe that the materials procured from our Chinese suppliers currently have the best overall performance and price compared to domestic alternatives. Escalating trade tensions between the United States and China have recently led to certain increased tariffs and trade restrictions. There can be no guaranty that these developments will not negatively impact the price of the felt used in our products. We believe we could obtain a similar performing felt and electrical cabling in the United States, but such sources would likely also charge a higher cost than our current suppliers, which would negatively impact our gross margins. 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 could be subject to foreign exchange risk.

Our international sales are typically denominated in U.S. dollars or Euros. As a result, we do not have significant direct exposure to currency valuation exchange rate fluctuations. However, because our products are sold internationally, to the extent that the U.S. dollar strengthens against the foreign currency of a customer or potential customer, we may find our products at a price disadvantage as compared with other non-U.S. suppliers. This could lead to our receiving lower prices or being unable to compete for that specific customer’s business. Consequently, currency fluctuations could adversely affect the competitiveness of our products in international markets.

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, privacy, 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.

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 applied for patents in the United States, Europe, Middle East, Asia and Australia, some of which have been issued. 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 re-design 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 misappropriated, infringed, or otherwise violated.

Our intellectual property may be stolen or infringed upon. 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 upon 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 also be subject to claims of intellectual property right infringement 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 and technology do not infringe 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 an intellectual property claim, 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 its offerings and may be unable to effectively compete. Any of these results would adversely affect our business, financial condition, and results of operations.

We may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and stock price, which could cause you to lose some or all of your investment.

Unexpected risks discovered following the Closing may arise that cause us to write-down or write-off assets, restructure our operations, or incur impairment or other charges that could result in losses. Even though these charges may be non-cash items and not have an immediate impact on our liquidity, the fact that we report charges of this nature could contribute to negative market perceptions about us or our securities. In addition, charges of this nature may cause us to violate net worth or other covenants to which we may be subject. Accordingly, our stockholders could suffer a reduction in the value of their shares.

Risks Related to Our Securities

To the extent that any shares of common stock are issued upon exercise of any of the warrants, the number of shares eligible for resale in the public market would increase.

We have 9,075,000 outstanding warrants to purchase 9,075,000 shares of common stock at an exercise price of $11.50 per share, which warrants will become exercisable on the later of (i) thirty (30) days following the Closing and (ii) twelve (12) months following the IPO.

To the extent that any shares of common stock are issued upon exercise of any of the warrants to purchase shares of common stock, 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 common stock.

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

Our Charter requires, unless we consent in writing to the selection of an alternative forum, that (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (iii) any action asserting a claim against us, our directors, officers or employees arising pursuant to any provision of the DGCL or our Charter or our bylaws, or (iv) any action asserting a claim against us or our directors, officers or employees governed by the internal affairs doctrine may be brought only in the Court of Chancery in the State of Delaware, except any claim (A) as to which the Court of Chancery of the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, (C) for which the Court of Chancery does not have subject matter jurisdiction, or (D) any action arising under the Securities Act, as to which the Court of Chancery and the federal district court for the District of Delaware shall have concurrent jurisdiction. If an action is brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, a court may determine that this provision is unenforceable, and to the extent it is enforceable, the provision may have the effect of discouraging lawsuits against our directors and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

Notwithstanding the foregoing, our Charter provides that the exclusive forum provision will not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Provisions in our Charter may inhibit a takeover of us, which could limit the price investors might be willing to pay in the future for our common stock and could entrench management.

Our Charter contains provisions that may hinder unsolicited takeover proposals that stockholders may consider to be in their best interests. We are also subject to anti-takeover provisions under Delaware law, which could delay or prevent a change of control. Together these provisions may make more difficult the removal of management and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities. These provisions include:

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

The Sponsor’s founder shares, private placement units, private placement shares, private placement warrants, and any shares of common stock issued upon conversion or exercise thereof are each subject to transfer restrictions pursuant to lock-up provisions in a letter agreement, dated May 19, 2020, between us and the Sponsor. Likewise, the Sellers party to the Registration Rights Agreement are contractually restricted from selling or transferring any shares of our common stock they received in connection with the business combination pursuant to the lock-up provisions contained therein. However, following the expiration of these lockup-up periods, neither such Sellers nor the Sponsor will be restricted from selling their shares of our common stock, other than by applicable securities laws. Additionally, investors in the PIPE Investment are not be restricted from selling any of their shares of our common stock, other than by applicable securities laws. As such, sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. Upon completion of the business combination, the Sponsor, the Sellers party to the Registration Rights Agreement, and the investors in the PIPE Investment collectively owned approximately 83.3% of the outstanding shares of our common stock.

As restrictions on resale end and registration statements are available for use, the sale or possibility of sale of shares by the Sponsor, the Sellers party to the Registration Rights Agreement, and the investors in the PIPE Investment could have the effect of increasing the volatility in our share price or the market price of our common stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

We may redeem the public warrants prior to their exercise at a time that is disadvantageous to such warrant holders, thereby making your public warrants worthless.

We will have the ability to redeem outstanding public warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, provided that the closing price of our common stock equals or exceeds $18.00 per share (as adjusted for stock splits, share dividends, reorganizations, recapitalizations and the like) for any twenty (20) trading days within a thirty (30) trading-day period ending on the third (3^rd) trading day prior to proper notice of such redemption. If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding warrants could force holders (i) to exercise the warrants and pay the exercise price therefor at a time when it may be disadvantageous to do so, (ii) to sell the warrants at the then-current market price when the holder might otherwise wish to hold their warrants or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, is likely to be substantially less than the market value of the warrants. The private placement warrants are not redeemable by us so long as they are held by the Sponsor or its permitted transferees.

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

Fluctuations in the price of our securities could contribute to the loss of all or part of your investment. The trading price of our securities could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. Any of the factors listed below could have a material adverse effect on your investment in our securities and our securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of our securities may not recover and may experience a further decline.

Factors affecting the trading price of our securities may include:

Broad market and industry factors may materially harm the market price of our securities irrespective of our operating performance. The stock market in general, and Nasdaq, have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of our securities, may not be predictable. A loss of investor confidence in the market for the stocks of other companies that investors perceive to be similar to us could depress our stock price regardless of our business, prospects, financial conditions, or results of operations. A decline in the market price of our securities also could adversely affect our ability to issue additional securities and our ability to obtain additional financing in the future.

There can be no assurance that the warrants will be in the money at the time they become exercisable, and they may expire worthless.

The exercise price for the outstanding warrants is $11.50 per share of common stock. There can be no assurance that the warrants will be in the money following the time they become exercisable and prior to their expiration, and as such, the warrants may expire worthless.

There can be no assurance that our common stock will be able to comply with the continued listing standards of Nasdaq.

The shares of our common stock and warrants are listed on Nasdaq. If Nasdaq delists the common stock from trading on its exchange for failure to meet the listing standards, we and our stockholders could face significant material adverse consequences including:

The grant and future exercise of registration rights may adversely affect the market price of our common stock.

Pursuant to the Registration Rights Agreement which is described elsewhere in the prospectus, the parties thereto can each demand that we register their registrable securities under certain circumstances and will each also have piggyback registration rights for these securities in connection with certain registrations of securities that we undertake. The registration of these securities will permit the public sale of such securities, subject to certain contractual restrictions imposed by the Merger Agreement. The registration and availability of such a significant number of securities for trading in the public market may have an adverse effect on the market price of our common stock.

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

We do not expect to pay cash dividends on our common stock. Any future dividend payments are within the absolute discretion of our board of directors and will depend on, among other things, our results of operations, working capital requirements, capital expenditure requirements, financial condition, level of indebtedness, contractual restrictions with respect to payment of dividends, business opportunities, anticipated cash needs, provisions of applicable law and other factors that our board of directors may deem relevant.

Risks Related our Status as a Public Company

The obligations associated with being a public company involve significant expenses and will require significant resources and management attention, which may divert from our business operations.

As a public company, we are subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act of 2002, as amended (“SOX”). The Exchange Act requires the filing of annual, quarterly and current reports with respect to a public company’s business and financial condition. SOX requires, among other things, that a public company establish and maintain effective internal control over financial reporting. As a result, we will incur significant legal, accounting and other expenses that we did not incur prior to the business combination. Our entire management team and many of our other employees will need to devote substantial time to compliance, and may not effectively or efficiently manage our transition into a public company.

We are currently an emerging growth company and a smaller reporting company within the meaning of the Securities Act, and to the extent we have taken advantage of certain exemptions from disclosure requirements available to emerging growth companies or smaller reporting companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), and we may take advantage of certain exemptions from various reporting requirements that are applicable to other companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of SOX, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. We intend to take advantage of the benefits of this extended transition period. This may make comparison of our financial statements with certain other public companies difficult or impossible because of the potential differences in accounting standards used.

We will remain an emerging growth company until the earlier of (i) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion (as adjusted for inflation pursuant to SEC rules from time to time), or (c) in which we are deemed to be a large accelerated filer, which means the market value of our shares of common stock that are held by non-affiliates exceeds $700 million as of the prior June 30^th, and (ii) the date on which we issued more than $1.00 billion in non-convertible debt during the prior three-year period. If we are not able to implement the requirements of Section 404 of SOX, including any additional requirements once we are no longer an emerging growth company, in a timely manner or with adequate compliance, we may not be able to assess whether our internal controls over financial reporting are effective, which may subject us to adverse regulatory consequences and could harm investor confidence and the market price of our securities.

USE OF PROCEEDS

All of the shares of common stock offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective amounts. We will not receive any of the proceeds from these sales.

We will receive up to an aggregate of approximately $104,362,500 from the exercise of the warrants, assuming the exercise in full of all such warrants for cash. We expect to use the net proceeds from the exercise of the warrants for general corporate purposes, which may include acquisitions and other business opportunities and the repayment of indebtedness. Our management will have broad discretion over the use of proceeds from the exercise of the warrants.

There is no assurance that the holders of the warrants will elect to exercise any or all of the warrants. To the extent that the warrants are exercised on a “cashless basis,” the amount of cash we would receive from the exercise of the warrants will decrease.

MARKET PRICE OF OUR SECURITIES

Our common stock and warrants began trading on The Nasdaq Stock Market (“Nasdaq”) under the symbols “EOSE” and “EOSEW,” respectively, on November 17, 2020. BMRG’s Class A common stock, warrants, and units were previously listed on the NYSE under the symbols “BMRG,” “BMRG.WS,” and “BMRG.U,” respectively. BMRG’s Class A common stock, warrants, and units each commenced separate public trading on June 1, 2020. BMRG’s units automatically separated into the component securities upon consummation of the Business Combination and, as a result, no longer trade as a separate security. Prior the Closing, each unit of BMRG consisted of one share of Class A common stock and one public warrant of BMRG, whereby each public warrant entitled the holder to purchase share of Class A common stock at an exercise price of $11.50 per share of Class A common stock. Upon the closing of the Business Combination, BMRG’s amended and restated certificate of incorporation, dated May 19, 2020, was replaced with the third amended and restated certificate of incorporation of Eos Energy Enterprises, Inc. which, among other things reclassified all shares of Class A common stock as common stock.

The following table includes the high and low bid prices for our common stock and warrants for the periods presented.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On November 16, 2020 (the “Closing Date”), Eos Energy Enterprises, Inc. (formerly known as B. Riley Principal Merger Corp. II), a Delaware corporation (the “Company”), consummated its acquisition of Eos Energy Storage, LLC., a Delaware limited liability company (“Eos”), pursuant to the Agreement and Plan of Merger, dated as of September 7, 2020 (the “Merger Agreement”). The transactions contemplated by the Merger Agreement are referred to herein as the “Business Combination.” 

In connection with the closing of the Business Combination (the “Closing”), the Company changed its name from “B. Riley Principal Merger Corp II” to “Eos Energy Enterprises, Inc.”, (“EOSE”). 

On November 12, 2020, the Business Combination was approved by the stockholders of the Company at a special meeting (the “Special Meeting”). The Business Combination was completed on November 16, 2020. In connection with the Business Combination, 6,442,195 shares of the Company’s common stock were redeemed at a per share price of approximately $10.10. Upon the Closing, the Company had 49,802,417 shares of common stock outstanding, 32,421,362 of which were held by non-affiliates of the Company. 

For purposes of the unaudited pro forma condensed combined financial information, the aggregate consideration for the Business Combination was $300 million or 30 million shares. 

Immediately prior to the Closing, pursuant to subscription agreements (the “Subscription Agreements”) with certain institutional and accredited investors (“PIPE investors”), the Company issued an aggregate of 4 million shares of common stock for $10.00 per share, for an aggregate purchase price of $40 million. 

Introduction

The following unaudited pro forma condensed combined financial statements present the combination of the financial information of the Company and Eos, adjusted to give effect to the Business Combination and the equity financing provided by the Equity Commitment Letter and Subscription Agreements with PIPE investors. The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X.

The following unaudited pro forma condensed combined balance sheet as of September 30, 2020 assumes that the Business Combination and equity financing had been completed on September 30, 2020. The following unaudited pro forma condensed combined statement of operations for the nine-months ended September 30, 2020 and for the fiscal year ended December 31, 2019 gives pro forma effect to the Business Combination and equity financing as if they had been completed on January 1, 2019.

The unaudited pro forma condensed combined financial statements have been presented for illustrative purposes only and do not necessarily reflect what the Company’s financial condition or results of operations would have been had the Business Combination occurred on the dates indicated. Further, the unaudited pro forma condensed combined financial information also may not be useful in predicting the future financial condition and results of operations of the Company. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available and analyses are performed.

This information has been developed from and should be read together with Eos’s audited and unaudited financial statements and related notes included herein this prospectus, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information included herein the prospectus and the sections titled “BMRG’s Management’s Discussion and Analysis of Financial Condition and Results of Operations,” incorporated in the Company’s amended registration statement filed with the U.S. Securities and Exchange Commission on November 13, 2020.

The Business Combination is accounted for under the scope of the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 805, business combinations (“ASC 805”), as a reverse recapitalization, with no goodwill or other intangible assets recorded, in accordance with GAAP. Eos has been determined to be the accounting acquirer based on the evaluation of the following facts and circumstances: 

ASC 805 provides that in identifying the acquiring entity in a transaction effected through an exchange of equity interests, all pertinent facts and circumstances must be considered, including: the relative voting rights of the stockholders of the constituent companies in the combined company; the existence of a large minority voting interest in the combined entity (if no other owner or organized group of owners has a significant voting interest); the composition of the board of directors and senior management of the combined company; the relative size of each company; and the terms of the exchange of equity securities in the transaction, including payments of any premium. The preponderance of the evidence discussed above supports the conclusion that Eos is the accounting acquirer in the Business Combination. Under this method of accounting, BMRG will be treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of Eos issuing stock for the net assets of BMRG, accompanied by a recapitalization. The net assets of BMRG will be stated at historical cost, with no goodwill or other intangible assets recorded.

Description of the Business Combination

At Closing Eos’s security holders received aggregate consideration with a value equal to $300 million.

In the Business Combination, the Company merged with and into Eos, and Eos became a wholly-owned subsidiary of the Company. Upon the Closing, the Company changed its name to “Eos Energy Enterprises, Inc.”

Financing for the business combination and for related transaction expenses consisted of: 

The unaudited pro forma condensed combined financial information has been prepared after giving effect to the Business Combination, and the redemption rights exercised by the Company’s public stockholders, where 6,442,195 public shares were redeemed.

Basis of the Pro Forma Presentation

As a result of the consummation of the Business Combination, the Company will adopt Eos’s accounting policies. Eos may identify differences between the accounting policies of the companies, that when conformed, could have a material impact on the consolidated financial statements of the combined entity.

Note 2 — Pro Forma Adjustments

(a) Adjustments to the Unaudited Pro Forma Condensed Combined Balance Sheet as of September 30, 2020 (in thousands)

The pro forma adjustments included in the unaudited pro forma condensed combined balance sheet as of September 30, 2020 are as follows:

Represents pro forma adjustments to the cash balance to reflect the following:

The Earn-out Shares will be issued, following the Closing, and within five Business Days after i) the closing share price of the Company’s shares on the principal securities exchange or securities market on which the shares are then traded equaling or exceeding $16.00 per share for any 20 trading days within any consecutive 30-trading day period during the period from the closing date to the fifth anniversary of the closing date (“Earn-out Period”) or ii) a change of control during the Earn-out Period.

A triggering event shall only occur once if at all, and, in no event shall the unitholders be entitled to receive more than an aggregate of 2,000,000 Earn-out Shares, and if a triggering event does not occur during the Earn-out Period, no Earn-out Shares shall be issued and the Company will not have any liability under this clause. Because this is a reverse acquisition, contingent shares issued to the stockholders of the accounting acquirer should be included in earnings per share from the date of issuance.

The Company has estimated the fair value of the contingently issuable shares to be $16.2 million. This is a preliminary valuation which will be finalized in the accounting for the reverse recapitalization based upon the fair value as of the close of the merger. This is initially recorded as a distribution to shareholders and is presented as contingently issuable shares. Upon the occurrence of a triggering event, any issuable shares would be transferred from contingently issuable shares to common stock and additional paid in capital. Any contingently issuable shares not issued as a result of a triggering event not being attained by the end of Earn-out Period will be cancelled.

(b) Adjustments to the Unaudited Pro Forma Condensed Combined Statements of Operations for the nine months ended September 30, 2020

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the consolidated financial statements and related notes thereto included elsewhere in this prospectus. In addition to historical information, this discussion contains forward-looking statements that involve risks, uncertainties and assumptions that could cause actual results to differ materially from management’s expectations. Factors that could cause such differences are discussed in “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors.”

Overview

We design, manufacture, and deploy reliable, sustainable, safe and scalable low-cost battery storage solutions for the electric utility industry.

We were originally incorporated in Delaware on June 3, 2019 as a special purpose acquisition company under the name B. Riley Principal Merger Corp. II (“BMRG”), in order to acquire, through a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

On November 16, 2020, we consummated the transactions contemplated by an Agreement and Plan of Merger (the “Merger Agreement”), dated as of September 7, 2020, by and among BMRG, BMRG Merger Sub, LLC, BMRG’s wholly-owned subsidiary and a Delaware limited liability company (“Merger Sub I”), BMRG Merger Sub II, LLC, BMRG’s wholly-owned subsidiary and a Delaware limited liability company (“Merger Sub II”), Eos Energy Storage LLC, a Delaware limited liability company (“Eos”), New Eos Energy LLC, a wholly-owned subsidiary of Eos and a Delaware limited liability company (“Newco”) and AltEnergy Storage VI, LLC, a Delaware limited liability company (“AltEnergy”). Pursuant to the Merger Agreement, (1) Merger Sub I merged with and into Newco (the “First Merger”), whereupon the separate existence of Merger Sub I ceased, and Newco continued as the surviving company (such company, in its capacity as the surviving company of the First Merger, is sometimes referred to as the “First Surviving Company”) and became our wholly owned subsidiary; and (2) immediately following the First Merger and as part of the same overall transaction as the First Merger, the First Surviving Company merged with and into Merger Sub II, whereupon the separate existence of the First Surviving Company ceased, and Merger Sub II continued as the surviving company and our wholly owned subsidiary.

Upon the closing of the business combination (the “Closing”), BMRG changed its name to “Eos Energy Enterprises, Inc.”

The business combination is accounted for as a reverse recapitalization. Eos is deemed the accounting predecessor and the combined entity is the successor SEC registrant, meaning that its financial statements for previous periods are disclosed in the registrant’s future periodic reports filed with the SEC. Under this method of accounting, BMRG will be treated as the acquired company for financial statement reporting purposes.

As a result of the business combination, Eos became the successor to an SEC-registered and NASDAQ-listed company, which will require us to hire additional personnel and implement procedures and processes to address public company regulatory requirements and customary practices. We expect to incur additional annual expenses as a public company for, among other things, directors’ and officers’ liability insurance, director fees, and additional internal and external accounting, legal, and administrative resources, including increased personnel costs, audit and other professional service fees.

The Znyth® technology and development of an energy storage solution has a required us to raise a significant amount of capital since its founding. We will require additional capital to fund ongoing investments in its technology, working capital requirements and its growth.

Key Factors Affecting Operating Results

Commercialization

We anticipate beginning full commercial production of our Eos Aurora Gen 2.3 150|600 DC Battery System and delivering its first shipments to customers during the fourth quarter of 2020. Our testing of Gen 2.3 batteries produced in limited quantities during 2020 have indicated performance at expected levels pending movement into commercial production. While we expect the performance to be the same upon commencement of full commercial production, the manufacturing line for this battery system has not been fully tested. If performance of the battery system does not meet our specifications, we may need to reduce the speed of production to ensure we have quality batteries that meet its performance specifications. Any delay in production could affect the delivery of batteries during the fourth quarter of 2020 and the first quarter of 2021.

We are also in the process of getting a third-party product safety certification from Underwriter Laboratories (UL) for the Eos Aurora Gen 2.3 150|600 DC Battery System. While we anticipate receiving UL Certification, the certification has been delayed due to Covid-19 and is expected in the fourth quarter of 2020 or the first quarter of 2021.

Ours growth strategy contemplates increasing sales of a commercial battery system through our direct sales team and Sales Channel Partners. We anticipate its customers to include utilities, project developers, Independent Power Producers and commercial and industrial companies. As we intend to expand its sales both in volume and geography, we have started discussions with several companies in North America, Europe, the Middle East and Asia about partnering on selling our product in these regions. For some of these sales channels we have begun discussions ranging from being a reseller of our product to being a joint venture partner in the manufacturing of its battery system. We expect to continue expanding the direct sales force in North America, adding direct sales people outside North America, and entering into strategic alliances to advance our sales growth globally.

Integration of Alliance Partners

We may in the future seek to construct one or more manufacturing facilities, thereby expanding our manufacturing footprint to meet customer demand. Provided the arrangement with its joint venture partner HI-POWER continues to meet the quality, cost and delivery timelines set by the HI-POWER Board of Directors, HI-POWER would maintain its exclusivity to manufacture the batteries for products sold and delivered in North America. If HI-POWER fails to meet the required performance metrics, we can establish our own manufacturing for North America either directly or through other partnerships.

For sales outside of North America, we may establish our own manufacturing facilities or may partner with other companies to manufacture our products. The construction of any such facility would require significant capital expenditures and result in significantly increased fixed costs. If we establish our own manufacturing facility, we have the right to transfer the manufacturing processes, technology and know-how from the HI-POWER JV to any new facility. We cannot be certain that we would be able to successfully establish or operate our own manufacturing facility in a timely or profitable manner, in the event that we had to exit HI-POWER with little time to prepare.

We install, commission and provide for the operation and maintenance of our battery systems deployed to date, and for those battery systems forecasted to be sold during the remainder of 2020. As our sales expand in volume and geography, we will need to contract and train third parties to perform this function on our behalf. We are currently in discussions with certain third-party servicing companies with the intention to have these partners in place before the end of 2020. Failure to establish these third-party service providers may slow our ability to increase our sales volume and expand our geographic presence.

Market Trends and Competition

The global energy storage market is expected to grow to a cumulative 1,095 gigawatts (GW), attracting an estimated $648 billion in future investment by 2040. We expect the United States to represent over 15% of this global market. Approximately 3.3 GW of energy storage was commissioned globally in 2019, which is expected to increase to 4.7 GW in 2020 according to Bloomberg New Energy Finance (“BNEF”). In addition, according to BNEF over 1.9 GW of new utility-scale energy storage was announced in 2019. Favorable regulatory conditions and the rapid growth of solar photovoltaic (PV) plus storage applications throughout the United States are expected to grow the utility-scale energy storage market from 172 megawatts (MW) / 345 megawatt hours (MWh) in 2019 to 6,631 MW/17,563 MWh by 2025. Globally, over the same period, we expect the energy storage market to grow at a 53% compound annual growth rate from 6,480 MWh in 2019 to approximately 83,000 MWh in 2025.

The principal areas in which we compete with other companies include:

Lithium-ion currently has 95% or more market share for the stationary battery industry. We will be the first commercially available battery that does not have a lithium-ion chemistry. We anticipate demand for its battery system using Znyth^® technology. This considers its unique operating characteristics, including a 100% discharge capability, flattened degradation curve and a 4-10 hour duration, as well as other characteristics related to safety and the cost of operating and maintaining our battery system. Our ability to successfully deploy our battery system technology and gain market share in the energy storage market will be important to the growth of our business. Our results could be negatively impacted by price reductions from large manufacturers of lithium batteries that seek to maintain or increase their market share.

We anticipate that other battery chemistries will emerge in future years thereby increasing its competitive landscape. As more battery chemistries are being developed, the competition for human talent will also increase. While we believe we can attract the right candidates given its unique battery, corporate culture and management team, our ability to retain and attract talented individuals will be important to the advancement of our technology and maintaining a competitive advance in the marketplace. As we make advancements with regards to our battery technology and offer next generation products, there is a risk that inventory on-hand as well as equipment or materials consumed in manufacturing or research and development may become impaired due to a change in our product design.

Regulatory Landscape

In North America, geographic distribution of energy storage deployment has been driven by regulatory policy with both federal and state level programs contributing to stable revenue streams for energy storage. Refer to the Business section for a description of these programs and the impact on our business.

Covid-19

We have implemented operational and protective measures to ensure the safety, health and welfare of our employees and stakeholders. This includes implementing work from home policies for non-essential employees, which constitutes 78% of our workforce. We have also ensured that all employees and visitors that visit our office have access to personal protective equipment and strictly enforces safe distancing. We will maintain these precautions and procedures until Covid-19 is under adequate control. To-date, Covid-19 has not had a material impact on our financials or our liquidity. To-date we have not materially altered any terms with customers, vendors or our financing sources.

Components of Results of Operations

Revenue

Eos has primarily generated revenues from limited sales as it prepares to launch its next generation energy storage solution that is scalable and can be used for commercial application. Eos expects revenues to increase as it scales its production to meet demand for the next generation of its product.

Cost of goods sold

Eos’s cost of goods sold includes materials, labor, and other direct costs related to the manufacture of its energy storage product for sale to customers. Other items contributing to its cost of sales are manufacturing overhead such as engineering expense, equipment maintenance, environmental health and safety, quality and production control and procurement. Cost of goods sold also includes the provision for excess, obsolete and slow-moving inventories, depreciation of manufacturing plant and equipment, warranty accruals, as well as shipping, logistics and facility related costs. Eos expects its cost of goods sold to exceed revenues in the near term as we continue to scale its business.

In August 2019, Eos established a joint venture, HI-POWER, that will manufacture the Gen 2.3 battery system on its behalf. Upon launching commercial production of its Gen 2.3 battery system, Eos expects cost of goods sold to include purchases of the Gen 2.3 battery system from HI-POWER for sale to its customers.

Research and development

Research and development expenses consist primarily of salaries and personnel-related costs as well as products, materials, third party services, and depreciation on equipment and facilities used in its research and development process. Eos expect its research and development costs to increase for the foreseeable future as Eos continues to invest in research and develop activities that are necessary to achieve its technology and product roadmap goals.

General and administrative expense

General and administrative expenses consist mainly of personnel-related expenses for executive and other administrative functions and expenses including corporate, executive, finance, and other administrative functions, expenses for outside professional services, including legal, audit and accounting services, as well as expenses for facilities, depreciation, amortization, travel, and marketing costs. Eos expects general, and administrative expenses to increase for the foreseeable future as Eos scales headcount with the growth of its business, and as a result of operating as a public company, including compliance with the rules and regulations of the SEC, legal, audit, additional insurance expenses, investor relations activities, and other administrative and professional services.

Grant expense, net

Grant expense, net includes expenses net of reimbursement related to grants provided by the California Energy Commission (“CEC”).

Sale of tax attributes

The sale of net operating loss represents the benefit recorded from the sale of its State of New Jersey net operating loss carryforwards to third parties.

Loss on equity in unconsolidated joint venture

The loss on equity in unconsolidated joint venture represents its proportionate share of the income or loss from its investment in HI-POWER LLC, a joint venture established with Holtec Power, Inc.

Interest expense

Interest expense consists primarily of interest incurred on its convertible notes, including the accretion of interest on convertible notes that contain embedded features that permit holders to demand immediate repayment of principal and interest.

Change in fair value, embedded derivative

The convertible notes issued during 2019 contained an embedded derivative feature that could accelerate the repayment of the convertible notes upon a qualified financing event not within its control. This embedded derivative resulted in the recording of a premium or discount on its convertible notes that was recognized in earnings upon their issuance.

Results of Operations

Comparison Nine Months Ended September 30, 2020 to Nine Months Ended September 30, 2019

The following table sets forth its operating results for the periods indicated:

Revenue

Revenue decreased by $0.2 million from $0.2 million for the nine months ended September 30, 2019 to insignificant amounts for the nine months ended September 30, 2020 as Eos transitioned its business to launch its next generation of energy storage solution, Gen 2.3, in the fourth quarter of 2020. Revenue during the nine months ended September 30, 2019 included limited product sales of initial versions of its energy storage product.

Cost of goods sold

Cost of goods sold decreased by $1.4 million from $7.6 million for the nine months ended September 30, 2019 to $6.2 million for the nine months ended September 30, 2020. The decrease results as Eos significantly reduced its manufacturing operations during the second half of 2019 and throughout 2020 pending the commercial launch of its Gen 2.3 battery system, which is expected in the fourth quarter of 2020. Cost of goods sold for the nine months ended September 30, 2019 primarily includes costs related to excess, obsolete and slow-moving inventory which reflects its decision to launch the next generation of its energy storage solution and discontinue sales of earlier products. In addition, impairment charges were incurred during the nine months ended September 30, 2019 for obsolete equipment relating to our prior generation battery. Cost of goods sold for the nine months ended September 30, 2020 primarily includes costs related to firm purchase commitments for Gen 2.3 battery systems in excess of the expected customer revenues that will be realized upon their sale to customers.

Research and Development

Research and development costs decreased by $1.7 million or 17% from $10.1 million for the nine months ended September 30, 2019 to $8.4 million for the nine months ended September 30, 2020. The primary drivers for the decrease were a reduction in payroll expenses due to lower headcount as Eos transitioned its efforts from research and development activities to focus on the commercial production of its next generation energy storage solution, lower depreciation expense from reduced investments in research and development equipment, a decline in materials associated with lower research and development activity, as well as an impairment charge included in R&D expenses during the nine months ended September 30, 2019 for obsolete equipment relating to our prior generation battery. These factors were partially was offset by increased expenditures during the nine months ended September 30, 2020 for testing of Gen 2.3 battery systems in preparation for its launch.

General and Administrative Expenses

General and administrative expenses increased by $3.0 million or 58% from $5.2 million for the nine months ended September 30, 2019 to $8.2 million for the nine months ended September 30, 2020. The increase is due to a $1.0 million increase in employee-related costs and professional fees incurred in connection with the proposed business combination with BMRG which are not capitalizable. Certain other transaction costs were capitalized and are presented as Deferred Transaction Costs in our balance sheet as of September 30, 2020.

Grant expense (income), net

Grant expense, net increased by $1.3 million or 238% from $0.5 million of income for the nine months ended September 30, 2019 to $0.7 million of expense for the nine months ended September 30, 2020. The increase results from more expenses incurred in excess of reimbursable costs related to its research and development grants from the CEC for the nine months ended September 30, 2020.

Loss on equity in unconsolidated joint venture

The loss from equity in unconsolidated joint venture results from losses incurred in connection with the initial pre-production costs of its joint venture HI-POWER LLC. The joint venture has not yet commenced its principal operations related to the manufacture of the Gen 2.3 battery system. The joint venture was formed in August 2019 and therefore there is no significant activity recorded for the joint venture for the corresponding nine months ended September 30, 2019.

Interest income

Interest income was not significant due to nominal investment balances during the nine months ended September 30, 2020 and 2019.

Interest expense

Interest expense was $0.1 million during the nine months ended September 30, 2020 as a result of an invoice securitization program entered into in January 2020 (see Liquidity section) as compared to insignificant amounts for the nine months ended September 30, 2019.

Interest expense — related party

Interest expense decreased by $7.5 million or 24% from $30.9 million for the nine months ended September 30, 2019 to $23.4 million for the nine months ended September 30, 2020. Eos’s convertible notes include an embedded feature that permits holders to demand immediate repayment of all outstanding principal and interest resulting in the immediate accretion of interest expense. During the nine months ended September 30, 2019, proceeds allocated to the issuance of convertible notes was $17.4 million and Eos recorded $30.9 million of interest expense related to these convertible notes that include a demand feature that could require repayment of principal and interest during 2019. During the nine months ended September 30, 2020, proceeds allocated to the issuance of convertible notes was $8.8 million, and Eos recorded $23.4 million of interest expense related to these convertible notes.

Loss on extinguishment of convertible notes — related party

The reduction in the loss on extinguishment of convertible notes of $6.1 million is the result of the modification in April 2019 of convertible notes issued during 2018 and January 2019.

Change in fair value, embedded derivative

The change in fair value of $3.2 million reflects the fair value of the embedded derivative feature on its convertible notes that was recorded through earnings.

Comparison of Year Ended December 31, 2019 to Year Ended December 31, 2018

The following table sets forth its operating results for the periods indicated:

Revenue

Revenue was $0.5 million for the year ended December 31, 2019 related to sales of its initial energy storage solution for specific customer application. There were no revenue producing operations in 2018.

Cost of goods sold

Cost of goods sold decreased by $1.4 million or 14% from $9.7 million for the year ended December 31, 2018 to $8.3 million for the year ended December 31, 2019. The decrease results primarily from a decrease of $3.9 million for costs incurred during the year ended December 31, 2018 to provide an upgraded, better performing battery system to a customer to replace an older system that was not performing in the manner required, offset by an increase of $2.5 million in costs incurred related to sales during the year ended December 31, 2019 and an increase of $0.2 million related to impairment costs incurred during the year ended December 31, 2019 for obsolete equipment relating to our prior generation battery.

Research and Development

Research and development costs decreased by $2.8 million or 19% from $14.6 million for the year ended December 31, 2018 to $11.8 million for the year ended December 31, 2019. The decrease results primarily from a reduction in payroll expenses due to lower headcount as Eos transitioned its efforts from research and development activities to focus on the commercial production of its next generation energy storage solution. The decrease is also due to lower depreciation expense from reduced investments in research and development equipment and a decline in materials associated with lower research and development activity.

General and Administrative Expenses

General and administrative expenses increased by $0.5 million or 8% from $7.2 million for the year ended December 31, 2018 to $7.7 million for the year ended December 31, 2019. The increase is primarily due to higher professional fees related to its formation of the joint venture HI-POWER LLC during the year ended December 31, 2019. This was offset by a decrease in payroll costs associated with a decline in headcount as well as a reduction to rent expense from its decision to vacate office space leased from a related party.

Grant expense (income), net

Grant expense (income), net decreased by $1.9 million or 133% from $1.4 million for the year ended December 31, 2018 to $(0.5) million for the year ended December 31, 2019. The decrease results from the timing of reimbursements and level of research and development activity related to its grants from the CEC.

Sale of state tax attributes

Eos recognized income of $4.1 million and $4.5 million for years ended December 31, 2019 and 2018, respectively related to the sale of its state net operating losses and research and development credit carryforwards under the New Jersey Economic Development Authority Technology Business Tax Certificate Transfer Program.

Loss on equity in unconsolidated joint venture

The loss on equity in unconsolidated joint venture results from its portion of HI-POWER LLC’s losses incurred in connection with its organization and start-up expenses. The joint venture was established in August 2019.

Interest income

Interest income was not significant due to nominal investment balances during the years ended December 31, 2019 and 2018.

Interest expense — related party

Interest expense increased by $49.6 million from $0.1 million for the year ended December 31, 2018 to $49.7 million for the year ended December 31, 2019. Eos’s convertible notes issued during 2019 included an embedded feature that permits holders to demand immediate repayment of all outstanding principal and interest resulting in the immediate accretion of interest expense. During the year ended December 31, 2019, proceeds allocated to the issuance of convertible notes was $19.3 million and Eos recorded $49.7 million of interest expense related to these convertible notes that include a demand feature that could require repayment of principal and interest during 2019. During the year ended December 31, 2018, interest expense on convertible notes issued of $0.1 million was not material.

Loss on extinguishment of convertible notes — related party

The loss on extinguishment of convertible notes of $6.1 million is the result of the modification in April 2019 of convertible notes issued during 2018 and January 2019.

Change in fair value, embedded derivative

The change in fair value of $0.7 million reflects the fair value of the embedded derivative feature on its convertible notes that was recorded through earnings. This embedded feature was not included in the convertible notes issued in 2020.

Liquidity and Capital Resources

As of September 30, 2020, Eos had cash and cash equivalents of $6.5 million. As Eos historically has not generated revenues sufficient to cover its operating expenses, and does not generate positive cash flows from operations, its ability to continue as a “going concern” depends in part on its ability to raise sufficient capital as further discussed in Note 1 to the unaudited financial statements.

Since its inception, Eos has financed its operations primarily through funding received from the private placement of convertible notes and the issuance of common and preferred units. During the year ended December 31, 2019, Eos conducted two rounds of bridge financing, raising total proceeds of $23.2 million through the issuance of convertible notes and preferred units. A portion of its convertible notes and preferred units were issued to a related party that, together with its affiliates, has a beneficial ownership in its company that exceeds 10%. This related party also serves as the agent for all of the convertible notes issued under the bridge financing arrangement. The convertible notes were issued at deep discounts of approximately 67% of the redemption value, requiring us to amortize the discount into interest expense over the period during which the principal and interest becomes payable to the holder. During the nine months ended September 30, 2020, Eos raised additional bridge financing proceeds of $18.1 million from the issuance of convertible notes and preferred units, $8.8 million of which is attributable to the convertible notes. The remaining bridge financing proceeds of $9.3 million is attributable to the fair value of preferred units issued. As of September 30, 2020, the outstanding balance of the convertible notes was $108.4 million.

In conjunction with the 2019 and 2020 bridge financing rounds, Eos entered into subscription agreements to sell preferred units equal to the face value of the convertible notes at a price of $0.50 per unit. During the nine months ended September 30, 2019, Eos allocated proceeds of $1.3 million to the issuance of 7.5 million preferred units. During the nine months ended September 30, 2020, Eos allocated bridge financing proceeds of $1.8 million to the issuance of 10.6 million preferred units. During the nine months ended September 30, 2020, Eos raised an additional $7.5 million of cash proceeds from the issuance of 15.0 million preferred units at a price of $0.50 per unit, separate from the bridge financing transactions. At September 30, 2020, Eos had 68.2 million common units outstanding and 106.3 million preferred units outstanding. As of September 30, 2020, its preferred units were convertible into approximately 250.5 million common units.

Eos expects capital expenditures and working capital requirements to increase as Eos seeks to execute on its growth strategy. Following the consummation of the business combination, Eos received $129.7 million from BMRG cash in trust and Eos believe it will be sufficient to meet its working capital and capital expenditure requirements for a period of at least twelve months from the date of this registration statement and sufficient to fund its operations until it commences commercial production. Eos may, however, need additional cash resources due to changed business conditions or other developments, including unanticipated delays in regulatory approval, supply chain challenges, disruptions due to COVID-19, competitive pressures, and regulatory developments, among other developments. To the extent that its current resources are insufficient to satisfy its cash requirements, Eos may need to seek additional equity or debt financing. If the financing is not available, or if the terms of financing are less desirable than Eos expects, Eos may be forced to decrease its level of investment in product development or scale back its operations, which could have an adverse impact on its business and financial prospects.

On January 10, 2020, Eos entered into a one-year invoice securitization facility (the “LSQ Invoice Purchase Agreement Facility”) pursuant to (i) an Invoice Purchase Agreement (the “IPA”), as sellers, (the “Seller”), and LSQ Funding Group, L.C. (“LSQ”), as purchaser (the “Purchaser”). Under the terms of the IPA, Eos contributes certain invoices, related collections and security interests (collectively, the “Invoices”) to LSQ on a revolving basis. Under the terms of the IPA, Eos issues to the Purchasers an ownership interest in the Invoices for up to $3.5 million in cash proceeds. The proceeds are used to finance LSQ’s purchase of the Invoices from Eos terminated this facility in September 2020.

The following table summarizes its cash flows from operating, investing and financing activities for the periods presented.

Cash flows from operating activities:

Eos’s cash flows used in operating activities to date have been primarily comprised of costs related to research and development, manufacturing of its initial energy storage products, and other general and administrative activities. As Eos continues towards commercial production, Eos expects its expenses related to personnel, manufacturing, research and development and general and administrative activities to increase.

Net cash used in operating activities was $10.4 million for the nine months ended September 30, 2020 which is comprised of its net loss of $45.3 million, adjusted for non-cash interest expense on its convertible debt of $23.4 million and other non-cash charges that includes provision for firm purchase agreements of $5.8 million, depreciation and amortization of $1.1 million, and change in fair value of embedded derivative of ($1.7) million. The net cash flows inflow from to changes in operating assets and liabilities was $5.9 million for the nine months ended September 30, 2020, primarily driven by a decrease in accounts receivable from the sale of its state tax attributes of $4.1 million and an increase in accounts payable and accrued expenses of $5.1 million.

Net cash used in operating activities was $20.8 million for the nine months ended September 30, 2019 which is comprised of its net loss of $60.7 million, adjusted for non-cash interest expense on its convertible debt of $30.9 million, change in fair value of embedded derivative of $1.5 million and other non-cash charges that includes depreciation and amortization of $1.8 million, impairment of property and equipment of $1.6 million and other non-cash charges of ($0.1) million. The net cash flows outflow from to changes in operating assets and liabilities was $2.0 million for the nine months ended September 30, 2019, primarily related to an increase in accounts payable and accrued expenses.

Net cash used in operating activities was $23.8 million for the year-ended December 31, 2019, which is comprised of its net loss of $79.5 million, adjusted for non-cash interest expense on its convertible debt of $49.7 million and other non-cash charges that includes depreciation and amortization of $2.1 million, change in fair value of embedded derivative of $0.7 million, impairment of property and equipment of $1.6 million loss on extinguishment of convertible notes — related party of $6.1 million and other non-cash charges of $0.2 million. The net cash flows outflow from changes in operating assets and liabilities was $5.3 million for the year ended December 31, 2019 primarily related to an increase in accounts receivable from the sale of its state tax attributes of $4.1 million and a decrease in accounts payable and accrued expenses of $1.1 million.

Net cash used in operating activities was $24.9 million for the year-ended December 31, 2018 which is comprised of its net loss of $28.5 million, adjusted for non-cash charges of $4.0 million related primarily to depreciation and amortization and the impairment of property and equipment. The net cash flow outflow from changes in operating assets and liabilities was $0.4 million for the year ended December 31, 2018.

Cash flows from investing activities:

Eos’s cash flows from investing activities, have been comprised primarily of purchases of property and equipment. Capital expenditures totaled $1.8 million for the nine months ended September 30, 2020 and $1.9 million for the nine months ended September 30, 2019. Capital expenditures totaled $2.3 million for the year ended December 31, 2019 and $1.7 million for the year ended December 31, 2018.

In August 2019, Eos began to make investments in the HI-POWER joint venture, which has the exclusive rights to manufacture its battery systems in North America, subject to meeting certain performance targets. Eos’s initial financial commitment to this joint venture is $4.1 million in the form of cash and special purpose manufacturing equipment. During the latter half of 2019, Eos made cash contributions of $0.6 million to HI-POWER and made additional contributions of $1.6 million during the nine months ended September 30, 2020. The special purpose manufacturing equipment will be classified as property and equipment on its balance sheet until it is fully commissioned and operational and has produced the first ten megawatts per hour of commercial product.

Cash flows from financing activities:

Through September 30, 2020, Eos has financed its operations primarily through the sale of common and preferred units and convertible notes.

Net cash provided by financing activities was $19.5 million for the nine months ended September 30, 2020 and included proceeds from the issuance of convertible notes of $8.8 million and the issuance of preferred units of $9.3 million.

Net cash provided by financing activities was $17.6 million for the nine months ended September 30, 2019 and included proceeds from the issuance of convertible notes of $17.4 million and the issuance of preferred units of $1.3 million. These proceeds were offset by a cash outflow related to the repayment of short-term notes payable of $1.0 million.

Net cash provided by financing activities was $22.1 million for the year ended December 31, 2019 and included proceeds from the issuance of convertible notes payable — related party of $19.3 million, and proceeds of $2.1 million attributable to the issuance of contingently redeemable preferred units. These proceeds were offset by a cash outflow related to the repayment of short-term notes payable of $1.0 million.

Net cash provided by financing activities was $30.1 million in the year ended December 31, 2018 and included proceeds from the issuance of preferred units of $24.9 million, convertible notes of $4.3 million and short-term notes payable of $1.0 million.

Off-Balance Sheet Arrangements

As a part of its working capital management, Eos sold certain grant receivables and state net operating losses through the LSQ Invoice Purchase Agreement Facility off-balance sheet arrangement described in the Liquidity and Capital Resources section. This facility was terminated in September 2020. During the nine months ended September 30, 2020, Eos sold $4.1 million of state tax attributes and $1.5 million of grant receivables under the invoice purchase agreement. Costs incurred on the sale was $0.1 million for the nine months ended September 30, 2020. These amounts are recorded in interest expense in the statements of operations.

As of December 31, 2019 and December 31, 2018, Eos did not have any off balance sheet receivables outstanding nor did Eos incur any costs associated with off-balance sheet arrangements. Eos did not have any other material off-balance sheet arrangements as of September 30, 2020, December 31, 2019 and December 31, 2018.

Critical Accounting Policies and Use of Estimates

Eos’s consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles. In preparing its consolidated financial statements, Eos makes assumptions, judgments, and estimates on historical experience and various other factors that Eos believes to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. Eos regularly reevaluates its assumptions, judgments, and estimates.

Eos’s significant accounting policies are described in Note 1, “Nature of Operations and Summary of Significant Accounting Policies,” in the Notes to the audited financial statements. Eos’s most significant accounting policies, which reflect significant management estimates and judgment in determining amounts reported in its audited financial statements were as follows:

Inventory Valuation

Inventory is stated at the lower of cost or net realizable value. The Company capitalizes inventory costs when, based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to be realized; otherwise, such costs are expensed as research and development. Inventory is evaluated for impairment periodically for excess, obsolescence and for instances where the inventory cost basis in excess of its estimated net realizable value. In estimating a provision for excess, obsolete and slow-moving inventory, Eos considers such factors as competitor offerings, market conditions and the life cycle of the product. If inventory on-hand is determined to be excess, obsolete or has a carrying amount that exceeds its net realizable value, Eos will reduce the carrying amount to its estimated net realizable value.

In preparation with the launch of its next generation energy storage solution, Eos will begin building inventory levels based on its forecast for demand. A significant decrease in demand could result in an increase in the amount of excess inventory on hand, which could lead to additional charges for excess and obsolete inventory.

Convertible Notes Payable

Eos record conventional convertible debt in accordance ASC 470-20, Debt with Conversion and Other Options. Conventional convertible debt is a financial instrument in which the holder may only realize the value of the conversion option by exercising the option and receiving the entire proceeds in a fixed number of shares or the equivalent amount of cash. Convertible instruments that are not bifurcated as a derivative, and not accounted for as a separate equity component under the cash conversion guidance are evaluated to determine whether their conversion prices create an embedded beneficial conversion feature at inception, or may become beneficial in the future due to potential adjustments. A beneficial conversion feature is deemed to be a nondetachable conversion feature that is “in-the-money” at the commitment date. The in-the-money portion, also known as the intrinsic value of the option, is recorded in equity, with an offsetting discount to the carrying amount of convertible debt to which it is attached. The intrinsic value of the beneficial conversion feature within its convertible debt, including amortization related to the debt discount recorded in connection with a beneficial conversion feature, was not material to its audited financial statements.

The convertible notes issued during 2020 and 2019 contained an embedded derivative feature that could accelerate the repayment of the convertible notes upon either a qualified financing event or the noteholders’ put exercise. During the nine months ended September 30, 2020 and 2019, embedded derivative liabilities with initial fair value of $0.4 and $0.6 were recognized, respectively. As of September 30, 2020 and December 31, 2019, the embedded derivatives were classified as current liabilities on the consolidated balance sheet and had fair values of $0.4 million and $1.7 million, respectively. During the nine months ended September 30, 2020 and 2019, a change in fair value of embedded derivative gain of $1.7 million and a loss of $1.5 million has been recognized, respectively. 

BUSINESS

Overview

We design, manufacture, and deploy reliable, sustainable, safe and scalable low-cost battery storage solutions for the electric utility industry. Our flagship product is the Eos Znyth^® DC battery system (the “Eos Znyth^® system”), with both front of the meter and behind the meter applications. The Eos Znyth^® system is the first stationary battery energy storage system (“BESS”) that is competitive with lithium-ion (“Li-ion”) in both price and performance, fully recyclable, does not require any rare earth or conflict materials, and is commercially available and scalable. Stationary BESS’s are used to store energy for many purposes, including stabilizing and reducing congestion of the power grid and reducing peak energy usage. When coupled with renewable energy sources such as photovoltaic (“PV”) solar and wind generation, the Eos Znyth^® system can store the energy that the renewable is producing and discharge it when the renewable is not producing energy, thus increasing the value of the renewable. Additionally, storage is used by commercial and industrial customers to save energy costs by reducing their peak usage thus reducing the transmission and distribution charges from utilities. We believe that energy storage serves as a central catalyst for modernizing and creating a more reliable and resilient, efficient, sustainable, and affordable grid.

EES LLC was founded in 2008 under the name Grid Storage Technologies, initially focusing on devolving the chemistry of its proprietary electrolyte-based battery technology and improving mechanical design and system performance. Our products, which are manufactured and developed in the United States, have the ability to play a pivotal role in the transition to a more sustainable, resilient and low carbon energy future. We are transitioning from an organization that focused primarily on research and development to one focused on commercialization of our energy storage solution and a scaled manufacturing platform. We produced our first proof of concept with generation 1 of the Eos Znyth^® system in 2015 (“Gen 1”) and began commercial shipments of our generation 2 Eos Znyth^® system in 2018 (“Gen 2”). As of August 2, 2020, we delivered approximately ten Eos Znyth^® systems comprised of over 2,500 Znyth^® batteries or approximately 5MWh. Each Eos Znyth^® system, which includes multiple battery formations and averages 250 batteries per system, is currently connected to, and monitored through, its battery management system. Each system is individually designed with the appropriate number of batteries to achieve the end user’s desired energy needs.

The Eos Znyth^® system uses our Znyth^® technology, a patented aqueous zinc-powered battery technology that offers a safe, scalable, fully recyclable and sustainable alternative to lithium-ion battery power. The Znyth^® technology requires just five core commodity materials that are derived from non-rare earth and non-conflict minerals that are Earth abundant and fully recyclable. The Eos Znyth^® system is also non-flammable and does not require any moving parts or pumps, allowing for simple maintenance and low-cost operation. Our competitive advantage is its Znyth^® battery technology, which employs a unique zinc-halide oxidation/reduction cycle packaged in a sealed, flooded, bipolar battery.

The Eos Znyth^® system offers an alternative to Li-ion at a cost per kilowatt hour (“KWh”) that is competitive. Unlike Li-ion, our commodity based aqueous zinc chemistry does not require high-cost heating, ventilation and air conditioning systems (“HVAC”) or fire suppression equipment due to our wide operating temperature range. Eos Znyth^® is manufactured with no toxic chemicals, which limits risk of catastrophic failure. Li-ion batteries have a history of explosions and fires, which are not an issue for our systems due to the stable, non-combustible chemistry used in our batteries. Our raw materials and components are readily available commodities with fewer supply constraints than competing technologies and are environmentally benign. Li-ion batteries use scarce, toxic rare earth materials that can be in short supply due to their use in electric vehicles, mobile phones and an array of other electronics. Our technology is highly scalable, easily installed and integrated into new or existing electric infrastructure. It also includes our proprietary battery management system, which optimizes our battery performance and protects the health and longevity of the battery. Our products are currently manufactured in the United States using a highly automated assembly line, which requires a fraction of the capital expenditure of equivalent Li-ion manufacturing processes. Our scalable manufacturing platform can be localized anywhere in the world in less than twelve months. Our technology is protected by a robust patent portfolio, with over 140 patents pending, issued or published in thirty-three (33) countries.

We sell our products through our direct sales force and through sales channels to developers, power producers, large utilities and commercial and industrial companies. Our sales focus is on use cases that require three (3) to ten (10) hours of battery storage, although our battery can be used for shorter durations as well. We are establishing a global sales presence by leveraging our sales channels and direct sales team. We work with customers to understand the use case for each battery storage project and proposes the best solution to maximize the economics for the end-user. Examples of customers and use cases for our systems include:

Our customers include leading renewable power producers, large utilities, developers and industrial companies such as NextEra Energy, Inc. (“NextEra Energy”), International Electric Power, LLC (“IEP”), Carson Hybrid Energy Storage, LLC (“CHES”) Hecate Energy LLC (“Hecate Energy”), Royal Dutch Shell plc (“Shell”), Duke Energy Corporation (“Duke Energy”), Pattern Energy Group LP and (“Pattern Energy”). We also sell to key system integrators and retail companies such as Siemens AG and Statkraft AS.

Additionally, our joint venture partner Holtec International (“Holtec”), a multi-billion dollar supplier to the nuclear power industry, is looking to “repower” decommissioned nuclear plants with renewable energy sources and battery storage. By using wind and solar energy sources combined with storage this creates a base load capable power plant that will be sold to the utilities. In addition, we are in discussions with other partners to do the same for coal plants that are in the process of closing. Repowering such plants requires a BESS with a flexible discharge duration of three to ten hours, the ability to cycle daily and provide a 100% discharge, and an energy output that does not degrade lower than 70% during its product lifetime. The Eos Znyth^® system meets all such requirements and we believe is well suited for this application.

Industry Overview

We believe that energy storage is on the verge of global wide scale deployment. As batteries increasingly become economical on a levelized cost of energy basis, we believe that utility-scale battery technology will be increasingly beneficial for a variety of solutions, including solar PV plus storage, peaking capacity, grid congestion and wind generation plus storage. We anticipate rapid increases in utility scale co-located renewable energy plus storage projects, especially in the United States, with most near and medium-term installation qualifying as utility scale. The reason for the increase is that combining a battery with an intermittent renewable energy source, such as wind or solar, allows for the storage of energy in the battery that can used when the intermittent source is not available, for example if the wind is not blowing or the sun is not shining.

According to Bloomberg New Energy Finance (“BNEF”) the global energy storage market is expected to grow to a cumulative 1,095 gigawatts (“GW”), attracting an estimated $660 billion in future investment by 2040. Based on BNEF, we believe the United States would represent over 15% of this global market. Approximately 3.3 GW of energy storage was commissioned globally in 2019, which is expected to increase to 4.7 GW in 2020 according BNEF. In addition, according to BNEF, over 1.9 GW of new utility-scale energy storage was announced in 2019. A significant factor in increased demand for energy storage, estimated to increase to 27% by 2030, is accelerating proliferation of renewable energy globally and in the United States. According to BNEF, the percentage of renewable energy in total electricity generation in the United States will change from 18% in 2019 to 36% by 2030 and solar energy is estimated to contribute 20% of total electricity supply. Favorable regulatory conditions such as the recent court decision validating FERC Order 841, along with state sponsored incentives in New York, California, Massachusetts and other states coupled with the rapid growth of solar PV plus storage applications throughout the United States are expected to grow the utility-scale energy storage market from 172 megawatts (“MW”) / 345 megawatt hours (“MWh”) in 2019 to 6,631 MW / 17,563 MWh by 2025. Based on management’s estimates, we estimate 1,250 GW of additional capacity from renewables to be delivered to the grid by 2024, leading to an increased demand for energy storage. Globally, over the same period, we expect the energy storage market to grow at a 53% compound annual growth rate from 6,480 MWh in 2019 to approximately 83,000 MWh by 2025. Below is a demonstration of the projected energy storage global market and the projected annual investment in the energy storage global market by region:

Limitations of Existing Technologies

Li-ion is the most prevalent incumbent energy storage technology, historically used in consumer electronics, electric vehicles and select transportation industries, and is the primary competition to the Eos systems. According to the U.S. Energy Information Administration, Li-ion accounted for 93% of all new energy storage capacity in the United States since 2012, growing at an annual rate of 55%. According to the Lazard Levelized Cost of Storage Version 4.0 Final report (“Lazard LCOS 4.0 Report”), Li-ion has an optimal MW capacity of between 5 kilowatts (“kW”) — 100 MW and an anticipated useful life of ten (10) years. The two primary ingredients for Li-ion batteries are lithium and cobalt.

Due to the factors described below, we believe that even though lithium supplies are generally forecasted to accommodate the global increase in demand in the near term, supply chains will likely become strained over time. Additionally, cobalt faces significant supply chain uncertainty that may constrain Li-ion battery growth.

Li-ion also suffers from certain inherent technological limitations. The life cycle can be limited under harsh conditions, due to the need for HVAC to keep the battery temperatures around 25C. Li-ion is also challenging to pair with solar in areas where the grid is not stable, which limits their usage in many locations around the world. Li-ion can be susceptible to overheating, explosions and related safety issues, such as the April 2019 lithium battery explosion near Phoenix Arizona. Most urban areas restrict the use of commercial size Li-ion batteries in buildings. Finally, Li-ion technology is difficult to recycle and dispose because it contains toxic materials.

There are a number of additional battery technologies utilized in the energy storage industry, such as:

The Eos Solution

Our battery systems offer a safe, sustainable and scalable alternative to Li-ion at a lower Levelized Cost of Storage (“LCOS”). Our solution consists of the Eos Znyth^® system, which integrates Eos Znyth^® batteries in a modular, outdoor-rated enclosure, in Eos’s Powerhouse or in modular, customized racks for indoor urban storage.

The key benefits of our solution include:

Our Competitive Strengths

Our key competitors are principally traditional Li-ion battery manufacturers, such as Samsung Electronics Co., Ltd, LG Chem, Ltd., Sungrow and Contemporary Amperex Technology Co. Limited. 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:

Our Strategy

Our mission is to accelerate clean energy by developing and deploying battery storage solutions that deliver the reliable and cost-competitive power that the stationary BESS market expects in a sustainable way. Key elements of its strategy include:

We plan to expand its resources and capabilities to meet our customers’ needs. This expansion will include adding employees to perform the work, as well as contracting and certifying qualified third parties to perform the commissioning and operations and maintenance services.

Our Products

The Eos Znyth^® system is designed to meet a wide range of requirements in the battery storage industry, including very large grid-scale energy storage projects, large and small solar projects, commercial or industrial projects, in-building urban projects or, while not currently part of its medium-term strategy, the residential market. With a three (3) to ten (10) hour discharge capability, immediate response time, and modular construction, the Eos Znyth^® system can be scaled and configured to reduce cost and maximize profitability in a wide range of battery storage projects. While the Eos Znyth^® system can be implemented in any configuration required, we offer three standard configurations: the Energy Block^TM (“Energy Block”), the Powerhouse and Customized racks.

Our innovative Energy Block packaging is a twenty (20) foot standard International Organization for Standardization shipping container and enables flexible options for system installation while significantly lowering the installation cost and accelerating permitting and installation time. The Energy Block is shipped with batteries and all electrical equipment integrated into a standard twenty (20) foot intermodal shipping container for drop and play convenience. Each sub-system includes pre-integrated strings of Eos Znyth^® batteries with DC wiring, DC system protection, support structure, enclosure and our battery management system. The Energy Block system integrates Eos Znyth^® batteries in a modular, outdoor-rated enclosure capable of delivering three (3) to ten (10) hours of continuous discharge at specified power. Each DC system is made-up of a containerized Energy Block integrating 144 Znyth^® Batteries and DC Control Cabinet. Each Energy Block is connected by a central DC Control Cabinet and is outfitted with our proprietary battery management system that monitors the voltage and temperature of each battery in the system, isolates faulty battery strings and provides real time visibility of battery operating limits. Energy Block is typically purchased by commercial and industrial customers and solar developers and is typically used for 40MWh and smaller battery systems, but can be used for larger systems as well.

The Powerhouse is designed for large battery storage projects by allowing for what we believe to be the highest power density in the smallest footprint. The Powerhouse is a pole barn type structure with a racking system that allows the modular Znyth^® batteries to be stacked up to twelve (12) batteries high, thus providing increased power density. Because the Znyth^® battery does not require HVAC or fire suppression systems and is simple to install, operate and maintain as compared to Li-ion. We believe the Powerhouse provides a cost-effective way to implement large Znyth^® battery storage systems. Furthermore, Powerhouse is typically purchased by utilities, independent power producers, solar and wind developers, and is typically used for larger systems above 40MWh.

Indoor Urban customized racks are modular configured racks offered primarily for indoor battery storage projects but could be used in a wide range of projects. The safety and modular nature of the Znyth^® battery allows for implementations in basements, rooftops, or any number of other locations in a building. Currently, most safety and fire codes only allow Li-ion batteries to be utilized outdoors in urban environments. Customized racks are typically purchased by commercial and industrial customers and are typically used for indoor systems that require a modular configuration.

Our Customers

Our largest customer in fiscal year 2019 was Duke Energy, which accounted for 26.1% of our revenues in fiscal 2019. Other customers include utilities, developers and industrial companies such as NextEra Energy, IEP, CHES, Hecate Energy, Shell and Pattern Energy.

Intellectual Property

The success of our business depends, in part, on our ability to maintain and protect its proprietary technologies, information, processes and know-how. We rely primarily on patent, trademark, copyright and trade secrets laws in the United States and similar laws in other countries, confidentiality agreements and procedures and other contractual arrangements to protect our technology. We are in the process of filing, or have recently filed, certain patents relative to our Gen 2.3 product that are subject to USPTO approval. A majority of our patents relate to cell chemistry, architecture and battery mechanical design, system packaging and battery management systems. We continually assess opportunities to seek patent protection for those aspects of its technology, designs and methodologies and processes that we believe provide significant competitive advantages. As of September 30, 2020, we had fourteen (14) patent families with over 140 patents pending, issued, or published in thirty-three (33) countries, protecting our technology and system architecture. Our issued patents are scheduled to expire between years 2035 and 2036.

We rely 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 require our employees to assign to us all of the inventions, designs and technologies the personnel develop during the course of 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.

Competition

The markets for our products are competitive, and we compete with manufacturers of traditional Li-ion and other battery storage systems. The principal areas in which it competes with other companies include:

Eos’s Znyth^® system competes principally with products from traditional Li-ion battery manufacturers such as Samsung Electronics Co., Ltd, LG Chem, Ltd., Sungrow and Contemporary Amperex Technology Co. Limited. We believe that its Znyth^® battery based system offers significant technology, safety and cost advantages that reflect a competitive differentiation over traditional energy storage technologies.

Regulatory Policy

In the United States and Puerto Rico, geographic distribution of energy storage deployment has been driven by regulatory policy with both federal and state level programs contributing to stable revenue streams for energy storage. Such policies include:

Government Incentives

The U.S. Congress is considering a variety of proposals for tax incentives that will benefit the energy storage industry, including in the form of tax credits. IRS private letter ruling 201809003 clarified that energy storage is eligible for federal tax credits if charted primarily by qualifying renewable resources. Proposals that have or are being considered by Congress include: (i) the establishment of an investment tax credit for business and home use of energy storage; (ii) the creation of a 30% investment tax credit for refueling costs and qualified nuclear power plant capital expenditures for each taxable year through 2023, thereafter declining each year until it reaches 10% in 2026; (iii) extension of the federal solar energy investment tax credit for ten (10) more years, keeping the credit at 30% through 2029; (iv) the consolidation of forty-four (44) federal energy tax incentives into three provisions to award credits for clean electricity, lower-emitting transportation fuels and energy efficient offices and homes; (v) the allowance of renewable electricity production and investment tax credits to be transferred on a limited basis to any entity involved in a renewable energy project, regardless of whether they have taxable income; and (vi) the extension of the production tax credit for energy produced from closed and open-loop biomass, geothermal, landfill gas, trash, qualified hydro and marine an hydrokinetic facilities to facilities that began construction by the end of 2019. There can be no assurance that all or any of the above proposals will be adopted by the U.S. Congress.

Employees

As of September 30, 2020, we had sixty-seven (67) employees with sixty-six (66) full-time employees and one (1) part-time employee. Of these full-time employees, thirty-nine (39) were engaged in research and development, three (3) in sales and marketing, fifteen (15) in operations and support and nine (9) in general and administrative capacities.

None of our employees are represented by a labor union. We have not experienced any employment-related work stoppages, and we consider relations with our employees to be good.

Facilities

Our corporate headquarters are located in Edison, New Jersey, in an office consisting of approximately 63,000 square feet of office, testing and product design space. We have a ten (10) year lease on its corporate headquarters, which expires on September 14, 2026.

We believe that our existing properties are in good condition and are sufficient and suitable for the conduct of our business for the foreseeable future. To the extent we need change as our business grows, we expect that additional space and facilities will be available.

Legal Proceedings

From time to time, we may be involved in litigation relating to claims arising out of our operations. There is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team in their capacity as such.
