PART I

Item 1. Business

Overview

Solid Power is a U.S.-based leader in solid-state battery technology and manufacturing processes. Our core technology is a sulfide-based solid electrolyte material, which replaces the liquid or gel electrolyte used in traditional lithium-ion battery cells. We believe our electrolyte technology has the potential to enable a step-change improvement in battery cell performance beyond what is currently achievable in conventional lithium-ion battery cells, including improved energy density, battery life, and safety performance. We are currently targeting the battery electric vehicle (“EV”) market due to the size and perceived demand for next generation battery technology but believe our technologies can have a broader application as they mature.

Commercialization Strategy

Our commercialization strategy is to manufacture and sell electrolyte to Tier 1 battery manufacturers and automotive original equipment manufacturers (“OEMs”) that choose to produce their own battery cells. We also intend to pursue licensing arrangements for our cell manufacturing processes and cell designs. This business model distinguishes us from competitors who are, or plan to be, commercial battery manufacturers and allows us to focus on our core strength of electrolyte development and production. Since we do not plan to produce commercial battery cells, we expect to have significantly lower capital requirements than cell manufacturers.

Technologies and Pilot Manufacturing

Our electrolyte is a sulfide-based material comprised of lithium sulfide (“Li2S”) and other inputs. We believe most OEMs and battery manufacturers have a technology roadmap that includes sulfide-based, solid-state cell products that can utilize our electrolyte. Our electrolyte is made from abundant materials produced at industrial scale in multiple geographical locations, except for the Li2S precursor material. Since we anticipate our Li2S need to significantly increase upon commercialization, we are taking a two-pronged approach to secure supply: sourcing from multiple global entities as well as working to develop in-house processes to produce material.

We believe sulfide-based solid electrolytes have the best-known balance of conductivity (i.e., the ability to move lithium ions quickly) and processability (i.e., the ability to allow cells to be produced on industry-standard roll-to-roll battery manufacturing equipment) out of all solid electrolyte classes. We develop our materials for stability and conductivity within each layer of the cell while also optimizing for areas such as cost and compatibility with conventional lithium-ion processing. We are also using customer feedback to tailor our electrolyte to meet customer requirements.

We currently produce electrolyte on two pilot manufacturing lines using a batch manufacturing process. The electrolyte we produce is used for customer sampling and internal cell development. In 2025, we intend to begin facility engineering and construction of a pilot electrolyte line using a continuous manufacturing process, which is expected to be commissioned in mid-2026. The continuous manufacturing line is expected to provide proof-of-concept of production-intent electrolyte manufacturing processes before proceeding to mass production.

Our current cell design is a multi-layered stacked pouch design made with a lithium nickel manganese cobalt oxide (“NMC”) cathode, silicon-based anode, and separator, each of which contains our electrolyte. We produce cells in sizes ranging from 0.2 Ah to 60 Ah. Our research and development teams are also working on lithium metal and anode-free cells. Longer-term, we intend to pursue the development of a nickel- and cobalt-free battery cell that could remove those costly and difficult to obtain materials. Each of these technologies are significantly earlier in development than our current NMC-silicon cell design.

We currently produce solid-state cells ranging from 0.2 Ah to 60 Ah on pre-pilot and pilot cell manufacturing lines. Our cell manufacturing processes were developed around industry-standard lithium-ion battery cell manufacturing processes and equipment. We currently manufacture all of our cell designs ourselves, including our cathodes and anodes, using materials sourced from external suppliers. We source other input materials from both industry-leading and emerging suppliers. The cells we produce are used to improve the performance of our electrolyte and support our partners’ cell development programs.

Partnerships

We collaborate with a number of industry leaders, including BMW of North America LLC (“BMW”), Ford Motor Company (“Ford”), SK On Co., Ltd. (“SK On”), and other OEMs and Tier 1 battery manufacturers. We expect to continue to work closely with these parties to improve our electrolyte and ultimately commercialize our technologies.

Benefits of Our Technology

We believe our electrolyte has the potential to provide the following benefits when incorporated into a solid-state cell as compared to traditional lithium-ion batteries:

If our electrolyte proves successful at delivering these benefits, we believe it would allow for reduced costs of battery packs through reduction of expensive pack engineering.

2024 Business Highlights

Deepened our relationship with SK On.

We entered into a series of agreements with SK On in January 2024 with the goal of strengthening our relationship. The agreements include a research and development technology license agreement (the “SK On R&D license”), line installation agreement, and electrolyte supply agreement (collectively, the “SK On Agreements”). During 2024, we conducted trainings with SK On personnel, designed a pilot cell manufacturing line for installation at SK On’s facility (the “SK On Line”), and began ordering and testing equipment for the SK On Line. The SK On Agreements are expected to allow SK On to develop solid-state cells based on our technology and operate the SK On Line using our electrolyte. For more information regarding our relationship with SK On, see “—Partnerships” below.

Increased electrolyte sampling.

Having demonstrated our ability to produce electrolyte at the pilot scale, we sampled electrolyte to multiple new potential customers and industry leaders in 2024. These samples have yielded constructive feedback that we are incorporating into our electrolyte products. We believe improved production capabilities and continued robust customer sampling will ultimately drive commercialization of our electrolyte.

Commissioned our Electrolyte Innovation Center.

During 2024, we commissioned our Electrolyte Innovation Center (“EIC”), where we conduct research and development to improve the performance, manufacturability, and cost of our electrolyte and precursor materials. The EIC is designed to be flexible, which we expect will allow us to rapidly change both the chemistry of our electrolyte and our manufacturing processes prior to transferring those learnings to our pilot electrolyte manufacturing lines.

Increased our Korean presence.

In October 2024, we invested $400,000 for a 20% equity interest in a strategic partner in the Republic of Korea. In addition, we loaned this partner approximately $5.6 million and received a warrant to purchase an additional 20% equity interest in the partner. This partner provides process engineering support for our pilot cell lines and is serving as the installer for the SK On Line. In addition to providing critical services in connection with the installation of the SK On Line, we view this investment as an opportunity to further our expertise of cell manufacturing processes and to better integrate ourselves in the Korean battery market. See Note 11 of our audited financial statements included in this Report for more information.

We also grew our presence in the Republic of Korea with the addition of several key employees focused on business development and program management in 2024. This expansion is designed to put us closer to the robust battery market in the Republic of Korea and Japan and allow us to strengthen our relationships with vendors, customers, and partners.

Progressed cell development.

After delivering A-1 cells to BMW in late 2023, we shifted our focus to improving the cell design for incorporation into A-2 cells as part of our BMW joint development agreement (“JDA”). During 2024, we made progress on multiple cell designs that we expect will improve cell performance as compared to our A-1 cells. We also made improvements to our production processes that we believe will allow us to produce higher quality prototype cells. These cells are designed to be produced on mostly conventional lithium-ion manufacturing equipment, which we believe is important to demonstrate the ability to commercially produce solid-state cells. We have worked collaboratively with BMW to enable BMW to utilize our learnings as it works to bring on-line its own solid-state cell development capabilities.

Validated by the U.S. Department of Energy.

In September 2024, we were selected by the U.S. Department of Energy (“DOE”) for a grant of up to $50 million under the Infrastructure Investment and Jobs Act, or Bipartisan Infrastructure Law. With this project, we intend to install the first globally known continuous manufacturing process of sulfide-based solid electrolyte materials for advanced all-solid-state batteries and expand our electrolyte production capabilities. The expansion is designed to further our technology roadmap and support anticipated small volume programs of current and future customers as they begin to transition from traditional lithium-ion to solid-state battery technology. Through this multi-year capital improvement project, we plan to significantly increase our annual production capacity, first to 75 metric tons in 2026 and then to 140 metric tons in 2028, in order to meet anticipated demand. In addition, we expect the continuous manufacturing process will allow us to produce electrolyte at a lower cost compared to today’s process.

In January 2025, we and DOE entered into an assistance agreement (the “Assistance Agreement”) to formalize the terms of the grant. Our cost share obligation under the Assistance Agreement is $60 million, and we are subject to certain reporting requirements and compliance obligations under the Assistance Agreement. We may not receive funding under the Assistance Agreement in the amount we expect due to an executive order issued in January 2025 relating to funds appropriated through the Bipartisan Infrastructure Law. For more information, see “Part I, Item 1A. Risk Factors—Risks Related to Development and Commercialization—We rely on government contracts and grants for a portion of our revenue and to partially fund our research and development activities, and such contracts and grants are subject to a number of uncertainties, challenges, and risks.”

2025 Development Objectives

Throughout 2024, many OEMs and battery manufacturers began projecting delayed commercial adoption of solid-state battery cells, with some projecting adoption in the late 2020s or early 2030s. We believe these projections are due, in part, to the uneven pace of battery science and the inherent challenges in predicting when research and development will be sufficient to reach commercialization.

Despite these projections, multiple new potential customers and industry leaders requested samples of our electrolyte in 2024, and we sampled a greater quantity of electrolyte in 2024 than 2023, with the majority of volume going to Asian Tier 1 battery manufacturers and OEMs in 2024. We believe this is largely due to Tier 1 battery manufacturers and OEMs coalescing around sulfide solid-state batteries as the preferred solid state cell architecture of the future and is a validation of our intended business model.

Through the sampling process, we have seen a variety in approaches to cell designs and, accordingly, have increased our focus on developing a strong understanding of how our electrolyte affects certain cell performance parameters. We believe this can give Solid Power a competitive advantage compared to electrolyte producers that do not have cell competencies and drive commercialization of our electrolyte. Pursuing this strategy will require us to reduce the amount of internal cell development we undertake in the short term, including scaling back on cell manufacturing as part of the automotive qualification process, though we still intend to work closely with our partners under their respective JDAs. We aim to facilitate worldwide cell development using our electrolyte and intend to leverage our cell capabilities to support our electrolyte development rather than to compete with Tier 1 cell manufacturers and OEMs. We believe this strategy gives us the best opportunity to be the electrolyte supplier of choice to Tier 1 battery manufacturers and OEMs that choose to produce their own battery cells.

As the solid-state battery landscape continues to evolve, we are focused on the following near-term objectives:

Drive electrolyte innovation and performance through feedback from cell development and customers.

As we work to scale our electrolyte business, we plan to focus the majority of our cell research and development on enhancing the feedback between our cell and electrolyte teams, with the ultimate goal of developing a superior understanding of how and why our electrolyte performs in a solid-state cell and using that knowledge to help our electrolyte customers improve their cell development. We believe we are the only entity with both pilot-scale sulfide electrolyte manufacturing and pilot-scale solid-state cell manufacturing capabilities, which positions us well to utilize feedback from our internal cell development team as well as feedback from customers and other external parties to improve our electrolyte products.

Continue executing on our electrolyte development roadmap.

To scale to commercial volumes of electrolyte production, we must first demonstrate the feasibility of our production methods. Our current pilot electrolyte manufacturing is a batch process. In 2025, we intend to begin facility engineering and construction of a pilot electrolyte line that is designed to manufacture electrolyte on a continuous process. To support this project, we ordered long lead-time equipment at the end of 2024. We believe a continuous manufacturing process is necessary to scale to commercial volumes and this pilot line is designed to allow us to learn and optimize the manufacturing processes ahead of full commercialization. We expect the continuous process pilot line will be commissioned in mid-2026.

Ramp electrolyte sampling and identify long-term customers.

To be successful in the long term, we must identify and develop customers for our electrolyte material. During 2025, we expect to continue sampling electrolyte to potential customers, partners, and industry leaders, explore additional partnership opportunities, and build upon the success we had in 2024. We have significant pilot production capacity, which we believe differentiates us from our competitors. Additionally, through our sampling process, we expect to tailor our electrolyte to meet customers’ specifications, which we believe will ultimately allow our electrolyte to be designed into our customers’ cell designs.

Execute on the SK On Agreements.

During 2025, we intend to complete the installation of the SK On Line by completing factory acceptance testing at various equipment vendors and site acceptance testing at SK On’s facility. Following installation, we expect to spend several months validating the SK On Line to ensure it meets contractual requirements. As part of the validation efforts, we expect to begin delivering electrolyte to SK On under the electrolyte supply agreement.

Remain fiscally disciplined.

We are focused on extending our runway through financial discipline while still investing appropriately in technology development and process improvements. We remain focused on maintaining and using our strong balance sheet to best position Solid Power to reach commercialization. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

Partnerships

Since we do not contemplate becoming a commercial cell manufacturer, one of our key goals is to establish and expand partnerships with Tier 1 battery manufacturers and OEMs. Our agreements with BMW, Ford, and SK On are non-exclusive, allowing us to pursue additional OEM or battery manufacturer relationships. The following sets forth the material terms of our agreements with each of BMW, SK On, and Ford.

BMW Group

We have a long-standing relationship with BMW, which began in 2016. Our relationship initially focused on cell research and development, and in 2017, we announced a partnership to jointly develop solid-state battery cell technology. In 2021, BMW and Solid Power expanded the partnership with BMW Holding B.V.’s (“BMW Holding”) participation in our $135.6 million Series B investment round, which closed in May 2021 (the “Series B Financing”) and with the execution of a JDA for EV cells for testing and vehicle integration with BMW.

The JDA with BMW sets out the collaborative framework for research and development and vehicle integration of solid-state battery cells. The JDA requires us to continue our research and development efforts towards deployment in BMW’s EVs. Additionally, the terms of the JDA permit BMW to share in certain intellectual property developed through these research and development efforts. Solid Power’s ability to share developments gained through the course of performance of the JDA with its other partners is limited in certain circumstances. The JDA also contemplates entering additional agreements with BMW for purchase and

pricing of electrolyte materials, integration into cell designs, as well as licensing our cell technology to cell producers. The key commercial terms of such additional arrangements have not yet been determined.

During 2022, we amended our JDA to provide BMW with a research and development-only license to certain of our intellectual property relating to cell manufacturing. The license allows for BMW to install a solid-state prototype cell manufacturing line based upon our proprietary information and BMW agreed to pay us $20 million between December 2022 and June 2024, subject to our achieving certain milestones. During 2024, we engaged with BMW in joint development and manufacturing activities at our facilities. Under the terms of the amended JDA, any intellectual property developed jointly by BMW and Solid Power at our facilities will be solely owned by us. In June 2024, we amended our JDA with BMW to (i) extend the term of the JDA to September 30, 2024 and (ii) revise the payment schedule under Amendment No. 4 to the JDA, effective November 1, 2022. In September 2024, we further amended our JDA with BMW to (i) extend the term of the JDA until we hit certain development milestones; provided that BMW will have termination rights in certain circumstances beginning on December 31, 2025, and (ii) revise certain deliverables and the timing to achieve various milestones and development targets and confirm cell performance requirements. We expect to negotiate a non-exclusive electrolyte supply agreement to supply BMW with our electrolyte material following commissioning of BMW’s prototype cell manufacturing line.

Pursuant to our Board Nomination Support Agreement, dated May 5, 2021, with BMW Holding (the “BMW Nomination Agreement”), BMW Holding has the right to nominate a director for election to our Board of Directors (the “Board”). Rainer Feurer, Senior Vice President at BMW and BMW Holding’s nominee, has served on our Board since December 2021 and was a director of Solid Power Operating, Inc. from May 2021 until December 2021, in each case pursuant to the BMW Nomination Agreement. Also, BMW Holding has the right to designate an individual to attend meetings of our Board and its committees in a non-voting, observer capacity.

SK On

In January 2024, we entered into the SK On Agreements. Under the SK On R&D license, SK On licensed our cell designs and manufacturing processes in exchange for payments totaling $20 million from 2024 to 2027, upon achievement of milestones. The SK On R&D license limits SK On to research and development activities and may not be used for commercial cell production. The line installation agreement provides that Solid Power will design, procure, and install the SK On Line at one of SK On’s Korea facilities in exchange for an estimated $22 million, upon achievement of milestones. SK On has also agreed to purchase our electrolyte for use on the SK On Line through the electrolyte supply agreement. Initially, under the electrolyte supply agreement, SK On will purchase electrolyte to validate the SK On Line. After validation, SK On is required to purchase at least eight metric tons of electrolyte from Solid Power through 2030, which it will use in advancing its cell technologies. Depending on volumes, we expect to receive at least $10 million from these electrolyte sales.

In October 2021, we entered into a non-exclusive JDA with SK On for joint production of our EV cells. In connection with the closing of the business combination with Decarbonization Plus Acquisition Corporation III, SK On invested $30 million into our company. The JDA contemplates that SK On and Solid Power will collaborate to validate Solid Power’s cell designs and production processes are scalable and compatible with existing lithium-ion production technology, enabling us to deliver pre-commercial cells to our OEM customers. The terms of the JDA permit SK On to share in the intellectual property developed through the joint production efforts required under the JDA. Following entry into the SK On Agreements, we and SK On began winding down our 2021 JDA, and we expect the JDA will expire by its terms on March 31, 2025.

Ford Motor Company

We started our relationship with Ford in 2018, when it participated in our Series A-1 equity financing. In 2019, we announced an investment by Ford and partnership to jointly develop solid-state battery cells using our pilot production line. In 2021, we expanded our partnership with Ford’s participation in the Series B Financing and the execution of a JDA relating to testing and vehicle integration of our EV cells. In December 2024, we amended our JDA with Ford to extend the expiration date to December 31, 2025 and to revise our cell material delivery obligations.

The JDA with Ford sets out the framework for the collaboration on the research and development of our cells. The JDA requires us to continue our research and development efforts towards deployment in Ford’s EVs. Additionally, the terms of the JDA permit Ford to share in certain intellectual property developed through these research and development efforts. Solid Power’s ability to share developments gained through the course of performance of the JDA with its other partners is limited in certain circumstances. The JDA also contemplates entering into additional agreements with Ford for purchase and pricing of electrolyte materials, integration into cell designs, as well as licensing our cell technology to cell producers. The key commercial terms of such additional arrangements have not yet been determined.

Intellectual Property

Our proprietary battery material and cell technology is protected through a combination of patents, patent applications, and trade secrets. Our patent portfolio includes technologies we invented, in addition to exclusive licenses obtained from the University of Colorado Boulder and Oak Ridge National Laboratory. Solid electrolyte materials and methods of production make up the largest portion of our patent application filings. Additional subjects include electrode and cell designs, cell processing methods, and electrolyte precursor methods, among others. We regularly file new applications in areas that are enforceable or reverse-engineerable. Processes for manufacturing sulfide-based solid electrolyte materials and solid-state cells make up the majority of our trade secrets. As of February 1, 2025, we owned or exclusively licensed 21 issued United States patents, 91 pending United States patent applications, 115 non-United States and PCT patents and applications, two registered United States trademarks, two pending United States trademarks, and five registered or pending non-United States trademarks. We further protect our intellectual property with non-disclosure agreements for all employees, consultants, and other third parties, material transfer agreements, and license agreements.

Competition

Performance improvements in next-generation battery and EV technology will contribute to global adoption of EVs. This trend has heightened competition and brought new entrants into the industry. We compete directly with both established and emerging materials suppliers and battery cell producers in the United States and abroad, and some of our competitors may be better capitalized or have more experience, superior products, or stronger relationships with their suppliers and customers.

A number of mature and development-stage companies are seeking to improve conventional lithium-ion battery cells or to develop new technologies for battery cells. Some of these companies have established relationships with OEMs and are in varying stages of development.

We believe our ability to compete successfully with both traditional lithium-ion and new battery technology will depend on several factors, including electrolyte performance and cost, safety, energy density, and battery life, and non-technical factors such as brand, established customer and partner relationships, and financial and manufacturing resources. We believe our relationships with BMW, Ford, and SK On can expedite our research and development process relative to our competitors by creating a feedback loop allowing for rapid and intelligent iterations.

Government Regulation and Compliance

We are subject to substantial regulation in the United Staes and abroad, including international, federal, state, and local laws which may vary from country to country and are subject to change. Government regulations frequently control how battery cells and their components are stored, transported, used and disposed of through environmental laws and regulations regarding hazardous substances and solid waste. These laws may impose strict, joint, and several liability for the investigation and remediation of areas where hazardous substances may have been released or disposed. In the ordinary course of operations, we, through third parties and contractors, may handle hazardous substances within the meaning of the Comprehensive Environmental Response, Compensation, and Liability Act and similar state statutes and, as a result, may be jointly and severally liable for all or part of the costs required to clean up sites at which these hazardous substances have been released into the environment. We are also subject to the strict requirements of the Resource Conservation and Recovery Act and comparable state statutes for the generation or disposal of solid waste, which may include hazardous waste. We believe we are in material compliance with applicable environmental laws and regulations. The cost of compliance with such laws and regulations has not had a material adverse effect on our capital expenditures, earnings, or competitive position and is not anticipated to have a material adverse effect in the future. However, we cannot guarantee that we are in full compliance with all environmental laws and regulations or that we will be able to comply with any future requirements or changes in such laws and regulations without significant costs.

The Occupational Safety and Health Act (“OSHA”) and comparable laws in other jurisdictions regulate the protection of the health and safety of workers. In addition, the OSHA hazard communication standard requires that information be maintained about any hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities, and the public.

In many cases, our products — including our cells and related technology — are or may in the future be subject to trade and export control laws and regulations in the United States and other jurisdictions where we do business.

Item 1A. Risk Factors

Our business is subject to numerous risks and uncertainties that you should be aware of in evaluating our business. If any such risks and uncertainties materialize, our business, prospects, results of operations, and financial condition could be materially and adversely affected.

The risks described below are not the only risks that we face. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial, could also have a material adverse effect on our business, prospects, results of operations, and financial condition. The summary risk factors described below should be read together with the text of the risk factors set forth immediately after the summary risk factors, and both the summary and text of the risk factors should be read together with the other information set forth in this Report, including our consolidated financial statements and the related notes, as well as in other documents that we file with the SEC.

Summary of the Material Risks Associated with Our Business

These risks include, but are not limited to, the following:

Risks Related to Development and Commercialization

The pace of battery technology development is not predictable. Delays or failures in accomplishing development objectives may postpone or prevent us from generating revenues from the sale of electrolyte or licensing of our cell technology. Expectations for when we will achieve various technical and production-level performance objectives depend in large part upon assumptions, estimates, measurements, testing, analyses, and data developed and performed by us, which may be incorrect or flawed.

Our expectations for when we will achieve various technical and production objectives reflect our current expectations and estimates. Whether and when we achieve these objectives depend on a number of factors, many of which are outside our control, such as:

Unfavorable changes in any of these or other factors beyond our control have impeded, and could continue to impede, our ability to achieve our objectives when planned. We may continue to experience unfavorable changes in factors beyond our control, and such unfavorable changes could have a material adverse effect on our business, prospects, results of operations, and financial condition. Additionally, we cannot predict market reaction or the impact on the price of our common stock and Warrants as we make announcements regarding our achievement, or failure to achieve, our objectives and publicly-disclosed milestones. Negative market reactions could result in volatility in the of the price of our common stock and Warrants.

We may not successfully develop our electrolyte for commercialization or attract customers. There is currently no commercial market for sulfide-based solid electrolytes and one may never emerge. Even if sulfide-based solid electrolytes are commercially adopted, we may not be able to effectively compete in any market.

Our business plan contemplates that we will sell our electrolyte to Tier 1 battery manufacturers and OEMs. However, our electrolyte is in the development stage, and we anticipate that our research and development efforts will extend in an iterative process even beyond delivery of our electrolyte to customers wishing to incorporate the material into their products. The continuous need to refine and optimize our products will require us to continue to perform extensive and costly research and development efforts. For example, through validation efforts, we have learned, and may continue to learn, that our electrolyte contains impurities or otherwise does not meet the quality or performance requirements of our customers. Fixing any such problems may require design changes or other research and development efforts, take significant time, and be costly. If our electrolyte fails to perform as expected, we could fail to attract or lose customers of our electrolyte.

Even if we successfully develop our electrolyte for commercialization, there is no established market for sulfide-based solid electrolyte. Our ability to sell our electrolyte to customers will depend on our or their success in developing battery cells which outperform those of traditional lithium-ion batteries. If battery manufacturers do not adopt sulfide-based cell architectures or if markets for sulfide-based solid electrolytes and solid-state battery cells do not develop in the time or to the level we anticipate, we may not be able to find customers to buy our electrolyte.

Further, we may have to compete with established companies that may be better capitalized or have more experience, superior products, or stronger relationships with their suppliers and customers. Potential customers may be wary of unproven products or not be inclined to work with less established businesses, and large organizations may have significant purchasing power and leverage in negotiating contractual arrangements with us. In addition, large organizations often have lengthy sales cycles, which may increase the risk that we spend substantial time and resources on a customer that ultimately elects not to purchase our products. If we are unable to successfully sell commercial volumes of electrolyte, we may be unable to achieve our financial projections, we may not recoup the costs associated with scaling production of our electrolyte, and our reputation and prospects may be adversely impacted, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

It will be challenging to develop sulfide-based solid electrolyte capable of production at volume and with acceptable performance, yields, and costs.

Our business depends on our ability to produce sulfide-based solid electrolyte at volume and with acceptable performance, yields, and costs. Developing the technology and know-how to produce electrolyte with acceptable performance at scale and cost is extremely challenging. We face significant obstacles to reaching commercial levels of electrolyte production, including:

If we are unable to overcome these challenges, we may not achieve commercial levels of electrolyte production. Significant delays in achieving, or failure to achieve, commercial production of our electrolyte could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We have not reached agreement with our partners on economic terms for the commercial sale of electrolyte or licensing of our cell technology. As a result, our projections of revenue and other financial results are uncertain.

Our agreements provide a framework for our cooperation with our partners, and certain of these agreements contemplate that we will enter into additional arrangements with our partners for the commercial sale of electrolyte or licensing of our cell technology. For example, under the electrolyte supply agreement, we and SK On have agreed, at SK On’s option, to make a commercially reasonable effort to enter into a commercial electrolyte supply agreement for commercial battery cell production by SK On. However, we have not reached agreement on key terms for the commercial sale of our electrolyte or licensing of our cell technology with any of our partners, and the structure for realizing the monetary value of our products is unknown. We cannot guarantee that we will be able to agree with our partners on key commercial terms or that any terms will be financially beneficial for us.

We may not successfully complete development of our cell designs, commercially license our cell technology to OEMs or cell manufacturers, or generate material revenue from our cell technology.

Our cell architecture is inherently complex and incorporates technology and components that have not been used in commercial battery cell production. As with our electrolyte, we expect our research and development efforts to extend in an iterative process even beyond delivery of cells using our technology to OEMs for validation in order to refine and optimize our cell technology. For example, we have learned, and may continue to learn, from validation efforts that our cells contain defects or errors that cause the cells not to perform as expected. Fixing any such problems may require design changes or other research and development efforts, take significant time, and be costly. Any failure of cells using our technology to perform as expected could harm our ability to commercially license our cell technology as well as sell our electrolyte.

We expect to need several additional years of research and development before cells using our technology will be advanced enough for us to realize material revenue from licensing our cell technology. We or our customers must overcome significant hurdles to complete development, validation, and automotive qualification of cells using our technology, including:

We have encountered, and expect to continue to encounter, engineering challenges and delays as we increase the dimensions and throughput of cells and cell components. In order to be commercially viable, cells using our technology will need to be capable of being produced at a high yield without compromising performance, and we or our customers will have to solve related packaging challenges in a way that is scalable and at an acceptable cost. If we or our customers are unable to overcome these engineering and mechanical hurdles, we may not succeed in commercially licensing our cell technology.

To generate material revenue from our cell technology, we will also need to identify customers willing to license our cell technology and enter into commercial license agreements. If we fail to bring our cell technology to market on a timely basis, products and technologies developed by others could render our cell technology obsolete or noncompetitive. Even if we complete development and succeed in entering into commercial license agreements, we may not start to generate revenues from such agreements until our customers have retrofitted or constructed and deployed facilities to build our cell designs at scale and we have constructed facilities to produce commercial volumes of our electrolyte. Any delay in development, automotive qualification, manufacturing scale-up, or construction of commercial electrolyte production facilities would delay our time to generate material revenue and may adversely impact our end-user relationships, including OEMs. Significant delays in providing commercial licenses to our technology could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We have only conducted preliminary safety testing on our cells. Any cells using our technology will require additional and extensive safety testing prior to being installed in EVs.

To achieve acceptance by OEMs and be installed in commercially available EVs, any cells using our technology will have to undergo extensive safety testing in addition to the preliminary safety testing we have conducted. We cannot guarantee that such tests will be successful. We have identified, and may continue to identify, different or new safety performance issues during our cell development that have not been present previously. For example, during late 2023 and early 2024, a few EV cells we produced went into thermal runaway during testing. We have identified the root cause for these performance issues and are actively working to improve safety performance, but we cannot guarantee that we will successfully mitigate the problem. We have made, and will continue to make, cell design and manufacturing process changes to address performance issues, which may lead to delays to or suspension of research and development projects or commercialization and in turn have a material adverse effect on our business, prospects, results of operations, and financial condition.

In addition, we have a limited frame of reference from which to evaluate the long-term performance of our technology. Issues or problems could arise once our technology has been deployed for a longer period, and we cannot guarantee that we will be able to detect and fix any defects or errors. If our customers determine our technology does not perform as expected, they may delay deliveries, terminate further orders, or initiate product recalls, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

If we are unable to attract and retain key employees and qualified personnel, our ability to compete could be harmed.

Our success depends on our ability to attract and retain our executive officers, key employees, and other qualified personnel, and our operations could be severely disrupted if we lost their services. Additionally, we have experienced, and may continue to experience, turnover in our executive officers, key employees, and other qualified personnel. For example, in the past 12 months, the Board appointed a new Chief Financial Officer and Treasurer and our Chief Operating Officer resigned. We continue to be highly dependent on the services of our executive officers and other senior technical and management personnel who would be difficult to replace. If we make strides in development of our technologies or competition in battery cell technology and EVs intensifies, the risk that competitors or other companies will seek to hire our personnel could increase. Further, competition for qualified personnel can be intense, and our ability to attract and retain them depends on our ability to provide competitive compensation and an attractive work environment. We may not be able to attract and retain qualified personnel in the future and may continue to experience turnover. Departure of key personnel or continued turnover may inhibit our ability to successfully attract and retain the personnel necessary to grow our business, and result in stockholder uncertainty and cause the price of our common stock and Warrants to decline, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

The non-exclusive nature of our agreements exposes us to the risk that our partners may elect to pursue other battery cell technologies or partners.

Our partners are motivated to develop and commercialize improved battery cell technologies. To that end, our partners have invested, and are likely to continue to invest in the future, in their own development efforts and, in certain cases, in agreements with our current and future competitors. If other technologies are developed more rapidly or are more efficient or effective than ours, our partners may elect to adopt and install a competitor’s cell technology or products over ours, which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We are seeking additional partners with which to collaborate in the development of our technology. Our inability to enter into development relationships with additional partners may impair our ability to control the timing of our development activities, sell our electrolyte, or generate licensing revenue.

We have entered into agreements with BMW, Ford, and SK On. We are actively seeking additional partnerships with other OEMs or Tier 1 battery manufacturers in an effort to diversify our development risk. However, the relationships we have with our

existing partners and our partners’ rights under their respective agreements may deter other OEMs and battery manufacturers from working with us. If we are not successful in establishing partnerships with other OEMs or battery manufacturers, we will remain highly dependent upon our existing partners. Because we generally cannot control the pace or extent of our partners’ collaborative efforts with us, the pace of our efforts generally must align with that of each partner. Further, our partners’ interests and priorities may not align with our own. As a result, a failure to diversify may prevent us from controlling the timing at which our technology matures to commercialization and harm our prospects.

If we fail to develop solid-state battery cells for commercialization or meet certain milestones under certain of our agreements within the required time frames, our partners may terminate the agreements.

We have entered into non-exclusive agreements, including with BMW, Ford, and SK On, to collaborate on the research and development of our cells. The terms of some of these agreements generally require us to continue our research and development of solid-state battery cells and component materials such that our products are capable of being deployed in EVs within the next few years. Although we have extended some of these agreements, our products remain in the development stage, and we cannot guarantee that we will be able to complete research and development in the time frame required by these agreements. If we do not meet these milestones or agree with our partners to extend or modify the terms of these agreements, we may not receive expected payments under these agreements and our partners may terminate their participation in the agreements without liability to us, which could adversely impact our reputation and prospects.

Our business depends on our ability to manage our relationships with existing and future partners, customers, suppliers, and contractors, and we may not successfully manage these business relationships.

We rely on a number of third parties in connection with development of our technology and performance on our contracts. Our partners, customers, suppliers, and contractors may have economic, business, or legal interests or goals that are inconsistent with ours. As a result, it may be challenging for us to resolve issues that arise in respect of the performance of our contracts, including our agreements with our partners. Any significant disagreements with these third parties may impede our ability to maximize the benefits of our partnerships and perform our contractual obligations and may slow the commercial roll-out of our technology. For example, we are utilizing a partner for the design and installation of the SK On Line, and a failure by our partner to satisfactorily and timely provide services could adversely impact our ability to fulfill our obligations under our line installation agreement with SK On. In addition, if our counterparties are unable or unwilling to meet their economic or other obligations under our agreements, we may be required to fulfill those obligations alone, which could delay our research and development progress.

The terms of certain agreements permit our partners to share in the intellectual property developed through the research and development efforts under their respective agreements. In certain circumstances, our ability to share developments gained through the course of performance of a particular agreement with our other partners may be limited, and our partners may be able to exploit certain of the intellectual property developed under their respective agreements in ways that are detrimental to us.

Certain of our agreements provide that, among other things, (i) any intellectual property jointly developed will be owned by both parties, with each party having the right to license that intellectual property to third parties in connection with the development of such party’s products, (ii) each party retains sole ownership of previously or independently developed intellectual property, and (iii) the partner receives a license to our solely developed intellectual property under the agreement for use in the partner’s products. To the extent that a development we make jointly with one of our partners involves such partner’s previously developed intellectual property, we may not be able to use any information gleaned in the course of performance under the agreement with such partner in performance of our other partners’ agreements, which could prevent us from scaling the development or deploying it in work with all of our partners. We cannot guarantee that we will maintain the access we need to our partners’ intellectual property, any jointly developed intellectual property will be adequately protected, or our partners will not seek to capitalize on jointly developed intellectual property for their sole benefit to the extent permitted by our agreements with them, such as through licensing agreements or other contractual arrangements they may enter with third parties that do not benefit us. Further, in certain of our agreements, we have agreed that our partners would receive certain rights to our intellectual property in certain circumstances, including if we were to fail to perform under commercial agreements that we may enter into in the future or otherwise abandon our business following the execution of such commercial agreements. If those provisions are triggered, certain of our partners may receive perpetual, irrevocable, royalty-free licenses to portions of our intellectual property, which may limit the profitability and competitive advantage offered by our intellectual property and adversely impact our revenue.

We are subject to risks relating to the construction and development of facilities for our short-term research and development and long-term electrolyte production requirements.

Our business plan contemplates that we will construct additional facilities for research and development and commercial electrolyte manufacturing. In the near term, we are working to expand our electrolyte material production capabilities at our existing

facilities through, for example, installation of equipment for continuous manufacturing of electrolyte. We may experience risks and complications associated with engineering and construction, including cost overruns and delays. Delay in the installation of a continuous production line could harm our development efforts and delay the expected expansion of our production capacity.

In the long term, and in connection with potential supply agreements, we will need to construct facilities to produce commercial volumes of our electrolyte. We have not secured a location or obtained the necessary licenses, approvals, permits, or consents for commercial-level electrolyte manufacturing facilities. In connection with constructing these facilities, we will need to identify and acquire the land or obtain leases for suitable locations that are appropriately zoned for activities involving hazardous materials, which will limit where we are able to locate our facilities and may require us to pay a premium for any such real estate. If we fail to do so, or otherwise encounter delays or lose necessary licenses, approvals, permits, consents, or commercial agreements, we could face delays or terminations of construction or development activities. If our planned facilities do not become operable on schedule, or at all, or become inoperable, production of our electrolyte and our business will be harmed.

Even if we successfully license our cell technology, we are subject to risks relating to production scale manufacturing of our cells through partners in the long term.

We aim to develop our cell technology in such a way as to enable our manufacturing partners to utilize existing lithium-ion cell manufacturing processes and equipment. While we believe development of a manufacturing process compatible with existing lithium-ion cell manufacturing lines could provide significant competitive advantages, modifying or constructing these lines for production of our products could be more complicated or present significant challenges to our manufacturing partners that we do not currently anticipate. As with any large-scale capital project, any modification or construction of this nature could be subject to delays, cost overruns, or other complications. Any failure to commence commercial production on schedule would likely lead to additional costs and could delay our ability to generate meaningful revenues. In addition, any such delay could diminish any “first mover” advantage we aim to attain, prevent us from gaining the confidence of OEMs, and open the door to increased competition. Any of the foregoing could hinder our ability to successfully grow our business and achieve a competitive position in the market.

Collaboration with third parties to manufacture our cell designs reduces our level of control over the manufacturing process. We could experience delays if our partners do not meet agreed upon timelines or experience capacity constraints. Potential disputes with partners could stop or slow cell production, and we could be impacted by adverse publicity related to our partners, whether or not such publicity is related to such partner’s collaboration with us. In addition, we cannot guarantee that our suppliers will not deviate from agreed-upon quality standards. Further, any partnerships with international third-party cell manufacturers or OEMs could expose us to the political, legal, and economic risks impacting the regions in which our partners’ manufacturing facilities are located, further reducing our control over the production process as we scale manufacturing.

If we are unable to enter into agreements with cell manufacturers on terms and conditions acceptable to us, we may need to contract with other third parties or create our own commercial production capacity. We may not be able to engage other third parties or establish or expand our own production capacity to meet our needs on acceptable terms or at all, and the expense and time required to adequately complete any transition or expansion may be greater than anticipated, which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We rely heavily on complex equipment for our operations, and the production of our technology involves a significant degree of risk and uncertainty in terms of operational performance and costs.

We rely heavily on complex equipment for our operations and the production of our electrolyte and cells. Integrating this equipment into the production of our electrolyte and cells is time intensive and requires us to work closely with the equipment providers to ensure that it works properly with our technology. This integration involves a degree of uncertainty and risk and may result in the delay in the scaling up of production or cause us to incur additional costs.

Our current manufacturing facilities require, and we expect that our future manufacturing facilities will require, large-scale machinery. Such machinery may unexpectedly malfunction and require repairs and spare parts to resume operations, which may not be available when needed. Because we do not maintain any redundancies in our research and development facilities, unexpected malfunctions of our production equipment may significantly affect our operational efficiency. In addition, because this equipment has not historically been used to produce sulfide-based solid electrolytes or build solid-state battery cells, the operational performance and costs associated with this equipment is difficult to predict and may be influenced by factors outside of our control, such as failures by suppliers to deliver necessary components of our products in a timely manner and at prices and volumes acceptable to us; environmental hazards and associated costs of remediation; difficulty or delays in obtaining governmental permits; damages or defects in systems; industrial accidents; and fires, seismic activity, and other natural disasters.

Problems with our manufacturing equipment could result in it not performing to our expectations, the personal injury to or death of workers, loss of production equipment, damage to our manufacturing facilities, monetary losses, delays, unanticipated fluctuations in production, environmental damage, administrative fines, increased insurance costs, and potential legal liabilities, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We rely on government contracts and grants for a portion of our revenue and to partially fund our research and development activities, and such contracts and grants are subject to a number of uncertainties, challenges, and risks.

We currently rely on government contracts and grants for a portion of our revenue and to partially fund our research and development activities. For example, the Assistance Agreement provides that DOE will provide us with funding of up to $50 million for our installation of equipment necessary for the continuous production of sulfide-based solid electrolyte material. Changes in government priorities or government funding reductions or delays could result in discontinuation of funding under, or termination of, our government contracts and grants. Further, the change in administration could increase this risk. On January 20, 2025, an executive order, titled Unleashing American Energy (the “Executive Order”), paused disbursement of funds appropriated through the Bipartisan Infrastructure Law pending further review. Because the Assistance Agreement is funded under the Bipartisan Infrastructure Law, our continued receipt of funding under the Assistance agreement could be delayed or cancelled. In addition, the Executive Order declared a policy of eliminating the “electric vehicle (EV) mandate.” The government has discretion under the terms of the Assistance Agreement to discontinue future funding as the result of insufficient progress, change in strategic direction, or lack of available funding. The government could determine that the Assistance Agreement no longer effectuates DOE priorities, interpret the terms of the Assistance Agreement to permit termination for this reason, and terminate the agreement. There can be no assurance that we will continue to receive funding under our government contracts and grants in the amounts that we expect or at all.

Further, as a government contractor or subcontractor, we must comply with laws, regulations, and contractual provisions relating to the formation, administration, and performance of government contracts and grants, which may impose added costs on our business. Although our management team and other personnel devote a substantial amount of time to compliance initiatives, we cannot guarantee that our efforts will be successful. Any failure to comply with such laws, regulations, and provisions or satisfy our obligations under such contracts and grants could lead to termination of contract; civil or criminal penalties; withholding, delay, or disallowance of payments to us; reimbursement of the government for amounts previously received; claims for damages from our partners; contract price adjustments or refunds; suspension or debarment from obtaining government contracts and grants; or non-ordinary course audits and internal investigations, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

Obtaining grant funding and selling to government entities can be highly competitive, expensive, and time consuming, often requiring significant upfront time and expense without any assurance of success. Awards of contracts and grants may be subject to appeals, disputes, or litigation. Government contracts also often contain provisions and are subject to laws and regulations that provide government customers with additional rights and remedies not typically found in commercial contracts. For example, government customers may terminate existing contracts for convenience, with short notice, and without cause. Government contracts may also require work to be performed or products to be manufactured in a particular jurisdiction, include preferential pricing terms, or require us to obtain special certifications. If such certification requirements change or we fail to timely achieve or maintain compliance with applicable requirements, we may be at a competitive disadvantage and disqualified from selling our technology to government or quasi-government entities.

In addition to government contracts and grants, we benefit from certain government subsidies and economic incentives, including tax credits, rebates, and other incentives, that support the development and adoption of clean energy technology. We cannot guarantee that government grants, subsidies, and incentives will be available to us at the same or comparable levels in the future. The Executive Order indicated that the government will consider eliminating subsidies that favor EVs. Any reduction, elimination, or discriminatory application of these grants, subsidies, or incentives may require us to seek additional financing, which may not be obtainable on commercially attractive terms or at all; adversely impact public sector demand for our technology; and diminish the competitiveness of the battery industry generally or our technology in particular. Any change in our ability to secure these grants, subsidies, and incentives could have a material adverse effect on our business, prospects, results of operations, and financial condition.

Substantial increases in the prices for our raw materials and components, some of which are obtained from a limited number of sources where demand may exceed supply, could materially and adversely affect our business.

We rely on third-party suppliers for materials, components, and equipment necessary to produce electrolyte and develop cells, including key supplies, such as Li2S, NMC, silicon, lithium metal foil, and manufacturing tools. We face risks relating to the timely availability, adequate quality, and consistency of these materials and components, including that we will be subject to demand shortages and supply chain challenges and generally may not have sufficient purchasing power to eliminate the risk of price increases for the raw materials and tools we need. Further, certain materials and components, including Li2S, are not currently produced at a

scale we believe necessary to support our proposed commercial operations. If we are unable to enter into commercial agreements with our current suppliers or our replacement suppliers on favorable terms, or these suppliers experience difficulties meeting our requirements, the development and commercial progression of our technology may be delayed.

Separately, we may be subject to various supply chain requirements regarding, among other things, conflict minerals and labor practices. We may be required to incur substantial costs to comply with these requirements, which may include locating new suppliers if certain issues are discovered. We may not be able to find any new suppliers for certain raw materials or components required for our operations, or such suppliers may be unwilling or unable to provide us with products.

Any disruption in the supply of materials, components, or equipment could temporarily disrupt our research and development activities or production of our electrolyte or cells until we obtain the required material. For example, in 2023, we received lower-quality NMC from one of our suppliers, which caused delays in cell production and affected the performance of our cells. Changes in business conditions, unforeseen circumstances, governmental changes, transportation disruptions, and other factors beyond our control or which we do not currently anticipate could also affect our suppliers’ ability to deliver components or equipment to us on a timely basis. Currency fluctuations, trade barriers, tariffs, or shortages and other general economic or political conditions may limit our ability to obtain key materials, components, and equipment for our electrolyte or cells or significantly increase freight charges, raw material costs, and other expenses associated with our business.

Accidents and severe weather conditions, natural disasters, or other catastrophic events could adversely impact our facilities and operations.

Some of our operations involve the manufacture and handling of a variety of explosive and flammable materials, and our research and development activities expose our employees to a number of potential occupational hazards. We have experienced, and may continue to experience, accidents from time to time. Among other things, we could experience leaks and ruptures, explosions, fires, transportation accidents involving our products, chemical spills, other discharges or releases of toxic or hazardous substances or gases, and other environmental and workplace safety incidents. For example, our employees could be exposed to toxic hydrogen sulfide as a result of the components we use being exposed to moisture, which could harm our employees, slow or stop production, and result in litigation, fines, increased insurance premiums, and workers’ compensation claims. Any such accident could harm our employees, damage our facilities, or adversely impact our operations. Further, because we do not have redundancies in our research and development facilities, an accident that damages our facilities could significantly disrupt our operations.

Severe weather conditions, natural disasters, and other natural events, such as floods, fires, earthquakes, typhoons, and health pandemics, such as the COVID-19 pandemic, could also affect our facilities and operations. For example, our facilities are located in a region which is affected by fires. In December 2021, the Marshall fire destroyed a significant number of buildings and disrupted a number of businesses in the Louisville, Colorado area. Further, our facilities and operations could also be adversely impacted by other events outside of our control, including power loss, telecommunications failures, cyberattacks, wars, riots, break-ins, and terrorist attacks. Given that we lack redundancies in our research and development facilities, any damage to our facilities could significantly disrupt our operations. Damage to our facilities or disruption of our operations could have a material adverse effect on our business, prospects, results of operations, and financial condition.

Further, we cannot guarantee that associated losses, claims, or liabilities will be covered by our insurance or any rights of indemnity or contribution that we have against others. We also cannot be sure that our existing insurance coverage will continue to be available on acceptable terms or in sufficient amounts to cover all of our potential losses. A loss that is uninsured or which exceeds policy limits could require us to pay substantial amounts, which could have a material adverse effect on our business, prospects, results of operation, and financial condition.

A global pandemic (e.g., COVID-19) and associated responses could disrupt our business and operations.

A global pandemic could have significant impact on economic activity and markets throughout the world. For example, the impact of COVID-19, including changes in consumer and business behavior, pandemic fears and market downturns, and restrictions on business and individual activities, created significant volatility in the global economy and led to reduced economic activity. Governmental authorities may implement measures in an attempt to contain a virus, such as travel bans and restrictions, quarantines, shelter-in-place orders, and business shutdowns, which may disrupt supply chains and impact our ability to continue our operations. Various aspects of our business cannot be conducted remotely, including many aspects of the research and development and manufacturing of our products.

The extent to which a future pandemic impacts our business, prospects, results of operations, and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, such as the duration and spread of the pandemic,

its severity, the actions taken to contain the virus or address its impact, the impact on us and our partners, contractors, suppliers, and customers, and how quickly and to what extent normal economic and operating activities can resume.

Risks Related to Industry and Market Trends

The battery market continues to evolve and is highly competitive, and we may not be successful in competing in this market or establishing and maintaining confidence in our long-term prospects among current and future partners and customers.

The battery market in which we compete continues to evolve and is highly competitive. To date, we have focused our efforts on our solid-state technologies, which we believe to be a promising alternative to conventional lithium-ion battery cell technology. However, lithium-ion battery cell technology has been widely adopted, and many of our current competitors have, and future competitors may have, greater resources than we do and may be able to devote greater resources to the development of their current and future technologies. These competitors may also have greater access to customers and may be able to establish cooperative or strategic relationships amongst themselves or with third parties that may further enhance their resources and competitive positioning. In addition, traditional lithium-ion battery manufacturers may continue to reduce cost and expand supply of conventional batteries and, therefore, adversely impact our prospects and ability to sell our products at market-competitive prices with sufficient margins.

Many OEMs, a number of battery technology companies, and other competitors are researching and investing in solid-state efforts and, in some cases, in battery cell development and production. For example, formation of the China All-Solid-State Battery Collaborative Innovation Platform (“CASIP”) was announced in 2024. CASIP has government-backed investment funds and intends to have a supply chain for solid state batteries up and running by 2030. We do not have exclusive relationships with any Tier 1 battery manufacturer or OEM to sell electrolyte or provide their future battery cell technologies, and investments made by these Tier 1 battery manufacturers or OEMs may result in technological advances earlier than, or superior in certain respect to, the technology we are developing. There are also a number of companies seeking to develop alternative approaches to solid-state technology. As new companies and larger, existing vehicle and battery manufacturers enter the solid-state battery cell space, we may lose any perceived or actual technological advantage we may have in the marketplace and suffer a decline in our market position.

The battery industry also competes with other emerging or evolving technologies, such as natural gas, advanced diesel, and hydrogen-based fuel cell powered vehicles. Developments in alternative technologies or improvements in battery technologies made by competitors may adversely impact the sales, pricing, and gross margins of our products. As technologies change, we will attempt to upgrade or adapt our products to continue to provide products with the latest technology. However, our products may become obsolete or our research and development efforts may not be sufficient to adapt to changes in or to create the necessary technology to effectively compete. If we are unable to keep up with competitive developments, including if competing technologies achieve lower prices or other emerging technologies enjoy greater policy support, our competitive position and growth prospects may be harmed. Similarly, if we fail to accurately predict and ensure that our solid-state technologies address customers’ changing needs or emerging technological trends, or if our customers fail to achieve the benefits expected from our technologies, our business will be harmed.

We must continue to commit significant resources to developing our technology in order to establish a competitive position, and these commitments must be made without knowing whether our investments will result in products customers will accept. We cannot guarantee that we will successfully identify customer requirements and develop and bring our electrolyte or cell technology to market on a timely basis, or that products and technologies developed by others will not render our electrolyte or cell technology obsolete or noncompetitive, any one of which could have a material adverse effect on our business, prospects, results of operation, and financial condition.

In addition, Tier 1 battery manufacturers, OEMs, and other customers may be less likely to purchase our electrolyte or license our cell designs if they are not convinced that our business will succeed in the long term. Similarly, suppliers and other third parties may be less likely to invest time and resources in developing business relationships with us if they are not convinced that our business will succeed in the long term. Accordingly, in order to build and maintain our business, we must instill and maintain confidence among current and future partners, customers, suppliers, analysts, ratings agencies, and other parties in our long-term financial viability and prospects. Maintaining such confidence may be complicated by certain factors, including those that are largely outside of our control, such as:

Our future growth and success are dependent upon consumers’ willingness to adopt EVs.

Our growth and future demand for our products are highly dependent upon the adoption by consumers of alternative fuel vehicles in general and EVs in particular. The market for new energy vehicles is still rapidly evolving, characterized by changing technologies, competitive pricing and factors, evolving government regulation and industry standards, and changing consumer demands and behaviors. For example, the federal government may seek to eliminate subsidies that favor EVs, which could adversely impact demand for our technology. If the market for EVs in general does not develop as expected, or develops more slowly than expected, our business, prospects, results of operation, and financial condition could be materially and adversely affected.

We may not be able to accurately estimate future demand for our technology, which could result in a variety of inefficiencies in our business, hinder our ability to generate revenue, and cause us to incur additional costs or experience delays.

It is difficult to predict future demand for our technology and appropriately budget for our expenses, and we may have limited insight into trends that may emerge and affect our business. We anticipate being required to provide forecasts of our demand to our suppliers prior to the scheduled delivery of products to our customers. Currently, there is no historical basis for making judgments on the demand for our technology or our ability to develop, manufacture, and deliver our products. If we overestimate our requirements, our suppliers may have excess inventory, which could indirectly increase our costs. If we underestimate our requirements, our suppliers may have inadequate inventory, which could interrupt manufacturing of our products and result in delays in shipments and revenues. In addition, lead times for materials and components that our suppliers order may vary significantly and depend on factors such as the specific supplier, contract terms, and demand for each component at a given time. If we fail to order sufficient quantities of product components in a timely manner, the delivery of our products to our customers could be delayed, which could have a material adverse effect on our business, prospects, results of operation, and financial condition.

Risks Related to Intellectual Property

We rely heavily on owned and exclusively-licensed intellectual property, including patent rights, trade secrets, copyrights, trademarks, and know-how, and we may be unable to protect and maintain access to these intellectual property rights.

Our success depends on our ability to protect and maintain our intellectual property rights, and we may not be able to prevent unauthorized use of our owned and exclusively-licensed intellectual property. We rely on a combination of the intellectual property protections afforded by patent, copyright, trademark, and trade secret laws in the United States and other jurisdictions, as well as license agreements and other contractual protections, to establish, maintain, and enforce rights and competitive advantage in our technology. In addition, we seek to protect our intellectual property rights through non-disclosure and invention assignment agreements with our employees and consultants and through non-disclosure agreements with business partners and other third parties. Despite our efforts to protect our intellectual property rights, third parties, including our vendors, partners, customers, and consultants, have and may in the future attempt to copy or otherwise obtain and use our intellectual property without our consent or may decline to license or defend necessary intellectual property rights to us on terms favorable to our business. Further, our technology and intellectual property may be subject to theft or compromise via more indirect routes. For example, our products or components thereof may be reverse engineered by partners, customers, or other third parties, which could result in infringement of our patents or theft of our know-how or trade secrets.

Detecting and addressing unauthorized use of our intellectual property is difficult and costly, and the steps we have taken or will take to prevent misappropriation may not be sufficient. Any enforcement efforts we undertake, including litigation, could require involvement of the licensor, be time-consuming and expensive, and divert management’s attention. Additionally, existing intellectual property laws and contractual remedies may not provide the protection needed to safeguard our intellectual property. For example, a significant portion of our patent rights have been obtained through exclusive licenses. Because we do not own those patent rights, we have less control over their maintenance and enforcement, which may limit our ability to maintain any competitive advantage those patent rights provide. Failure to adequately protect our owned and exclusively-licensed intellectual property may result in our

competitors using our intellectual property to offer products, loss of our competitive advantage, and harm to our reputation and could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We have not performed exhaustive searches or analyses of the intellectual property landscape of the battery industry and cannot guarantee that our technology, or its ultimate integration into EVs, does not infringe intellectual property rights of third parties. We may need to defend ourselves against intellectual property infringement claims, which may be time-consuming and cause us to incur substantial costs.

Others, including our competitors, may hold or obtain intellectual property rights that would prevent, limit, or interfere with our ability to make, use, develop, sell, license, lease, or market our technology or products. From time to time, we may receive inquiries from third parties relating to whether we are infringing their intellectual property rights and third parties may seek court declarations that they are not infringing upon our intellectual property rights. The defense of infringement claims may divert management’s attention, and we may incur significant expenses in addressing these matters. If we are determined to have infringed upon a third party’s intellectual property rights, we may be required to:

We license patents and other intellectual property from third parties and may face claims that our use of this intellectual property infringes the rights of others. In such cases, we may seek indemnification from our licensors as permitted by our license agreements, but our rights to indemnification may depend on a number of factors, such as our use of the technology and whether we choose to retain control over conduct of the litigation. If our rights to indemnification are unavailable or insufficient to cover our costs and losses, future infringement claims could have a material adverse effect on our business, prospects, results of operations, and financial condition.

There are risks to our intellectual property based on our international business operations.

Patent, copyright, trademark, and trade secret laws vary significantly throughout the world. A number of foreign countries do not protect intellectual property rights to the same extent as the United States, and our intellectual property rights may not be as strong or as easily enforced outside of the United States. Efforts to protect against the unauthorized use of our intellectual property outside of the United States may be unsuccessful. Our international business operations may also expose us to material risks of theft of our technology and other intellectual property, including technical data, business processes, production processes, formulas, data sets, or other sensitive information. Conducting business in certain jurisdictions, housing our technology and other intellectual property abroad, and licensing our technology to foreign partners may increase our exposure to these risks.

Our patent applications may not result in issued patents, and our patent rights may be contested, circumvented, invalidated, or limited in scope.

Our patent portfolio includes patent applications. If our patent applications do not result in issued patents, the disclosures in those applications would become available to the public and we may be unable to prevent others from commercially exploiting products similar to ours. The status of patents involves complex legal and factual questions, and the breadth of claims allowed is uncertain. As a result, we cannot be certain that our patent applications will result in patents being issued or that our patents, and any patents that may be issued to us, will afford us adequate protection against competitors with similar technology. Others have numerous patents and pending patent applications in the same fields as our technology and may claim priority, which could prevent us from obtaining a particular patent. Our existing patents and patent applications, including those we have exclusively licensed, could be challenged on the basis that they are otherwise invalid or unenforceable. Patent applications filed in foreign countries may be subject to laws, rules, and procedures that differ from those of the United States, and we cannot guarantee that foreign patent applications related to issued U.S. patents will be issued.

Risks Related to Our Limited Operating History

Our business plan has yet to be tested, and we may not succeed in executing on our strategic plans, including commercialization.

As a research and development stage company, we face a number of difficulties normally encountered by new enterprises, including substantial risks and expenses in the course of establishing or entering new markets, organizing operations, and undertaking marketing activities. The likelihood of our success must be considered in light of these difficulties and the competitive environment in which we operate. There is nothing at this time upon which to base an assumption that our business plan will prove successful, and we may not be able to generate significant revenue, raise additional capital, or operate profitably. We will continue to encounter challenges frequently experienced by early commercial stage companies, including scaling up our infrastructure and managing our headcount, and may encounter unforeseen expenses, difficulties, or delays in connection with our growth. In addition, as a result of the capital requirements of our business, we can be expected to continue to sustain substantial operating expenses without generating sufficient revenue to cover expenditures. Any investment in our company is therefore highly speculative and could result in the loss of your entire investment.

It is difficult to predict our future revenues and appropriately budget for our expenses, and we have limited insight into trends that may emerge and affect our business. If actual results differ from our estimates or we adjust our estimates in future periods, our business, prospects, results of operations, and financial condition could be materially and adversely affected. Furthermore, our financial performance in one period may not be indicative of financial performance in future periods.

We are a research and development stage company with a history of financial losses and expect to incur significant expenses and continuing losses for the foreseeable future.

We incurred an operating loss of approximately $105.3 million for the year ended December 31, 2024 and an accumulated deficit of approximately $181.2 million from our inception in 2012 through December 31, 2024. We believe we will continue to incur operating losses each quarter until the significant sale of our electrolyte or production of our cell designs begins. Development in materials sciences is not linear, and the pace of our efforts will depend in significant part on the level of engagement and extent of resources devoted to these efforts by our partners, making it difficult to predict when we will begin to recognize material revenues from our technology. In addition, we currently rely on a limited number of customers for a significant portion of our revenue. The loss of any of our major customers may increase our operating losses and have a material adverse effect on our business, prospects, results of operations, and financial condition.

The rate at which we will incur losses may be significantly higher in future periods as we, among other things, continue to incur significant expenses in connection with the design, development, and manufacturing of our technology; expand our research and development activities; invest in additional research and development and manufacturing facilities and capabilities; build up inventories of raw materials and other components; commence sales and marketing activities; develop our distribution infrastructure; and increase our general and administrative functions to support our growing operations. We may find that these efforts are more expensive than we currently anticipate or that these efforts may not result in revenues, which would further increase our losses.

We may require additional capital to support business growth, and this capital might not be available on commercially reasonable terms or at all.

Our expectations regarding our capital needs are dynamic, changing, and subject to various risks and uncertainties, including those described herein. For example, our budgets assume, among other things, that our development timeline progresses as planned and our corresponding expenditures are consistent with current expectations, but our timeline and expectations been derived based on internal estimates and discussions with our key partners only and do not factor in the possibility of additional partnerships. Further, our capital expenditures and operating and development requirements have increased materially as we further our research and development efforts, scale up production operations with our partners, and incur expenses as a public company, including insurance, financial reporting, legal, and audit costs. As we continue our progress toward commercialization, we expect that our operating expenses will continue to increase.

We may need additional capital before we recognize material revenues, which may not be available on commercially reasonable terms or at all. As a result, we may need to access the debt and equity capital markets to obtain additional financing in the future. Our ability to obtain additional financing will be subject to a number of factors, including:

These factors may make the timing, amount, terms, or conditions of additional financings unattractive to us. If we raise additional funds by issuing equity, equity-linked, or debt securities, those securities may have rights, preferences, or privileges senior to the rights of our then-issued and -outstanding equity or debt, and our existing stockholders may experience dilution. If we are unable to generate sufficient funds from operations or raise additional capital, we may be forced to take actions to reduce our capital or operating expenditures, including by not seeking potential acquisition opportunities, eliminating redundancies, or reducing or delaying our production facility expansions, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We may be unable to adequately control the costs associated with our operations and the components necessary to develop our technology.

We require significant capital to develop our technology. As we develop our technologies and scale our operations, we expect to continue to incur significant expenses, including those relating to research and development, raw material procurement, leases, sales, and distribution. Our ability to become profitable in the future will depend on our ability to successfully develop and market our products as well as our ability to control our costs. If we are unable to efficiently design, appropriately price, and sell and distribute our products, our anticipated margins, profitability, and prospects would be adversely impacted.

Our business and prospects, including our ability to control costs, could be adversely impacted by changes in macroeconomic conditions, such as changes in administration, inflation, interest rates, slower growth or recession, tariffs, international conflicts, trade disputes, sanctions, and government efforts to stimulate or stabilize the economy. Changes in macroeconomic conditions could happen rapidly, and we may fail to prevent or limit our losses or exposures.

If we fail to effectively manage our future growth, we may not be able to market and license the technology and know-how to sell our electrolyte or manufacture our cells.

We intend to use our cash on hand to execute on our near-term objectives, which include driving electrolyte innovation and performance through feedback from cell development and customers, continuing to execute on our electrolyte development roadmap, ramping electrolyte sampling and identifying long-term customers, executing on the SK On Agreements, and remaining fiscally disciplined. That said, our management team has considerable discretion in the application of the funds available to us. We may invest these funds in a manner that does not improve our ability to market and license the technology and know-how to manufacture our cells or sell our electrolyte and ultimately results in a significant, or any, return for our stockholders. In addition, pending their use, we may invest our cash on hand in a manner that does not produce income or that loses value. Failure to effectively manage our growth could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We may not succeed in establishing, maintaining, and strengthening our brand, which could adversely impact customer acceptance of our technology.

Our business and prospects depend on our ability to develop, maintain, and strengthen our brand. The battery industry is intensely competitive, and we may not be successful in building, maintaining, and strengthening our brand. Some of our current and potential competitors, including many cell manufacturers and OEMs around the world, have greater name recognition, broader customer relationships, and substantially greater marketing resources than we do. If we do not develop and maintain a strong brand, we may lose the opportunity to build a critical mass of customers, which could adversely impact customer acceptance of our technology and have a material adverse effect on our business, prospects, results of operations, and financial condition.

Risks Related to Finance and Accounting

Incorrect estimates or assumptions by management in the preparation of our consolidated financial statements could adversely impact our reported assets, liabilities, income, revenue, or expenses.

The preparation of our consolidated financial statements requires management to make critical accounting estimates and assumptions that affect the reported amounts of assets, liabilities, stockholders’ equity, revenue, income, and expenses during the

reporting periods. Incorrect estimates and assumptions by management could result in reported amounts that are overstated or understated and have a material adverse effect on our business, prospects, results of operations, and financial condition.

We incur significant expenses and administrative burdens as a public company.

As a public company, we are subject to the reporting requirements of the Exchange Act, SOX, stock exchange listing requirements, and other applicable securities rules and regulations. These rules and regulations require us to incur significant legal, accounting, and financial compliance costs. In addition, advocacy efforts by stockholders and third parties may prompt additional governance and reporting requirements. Our management team and other personnel devote a substantial amount of time to compliance initiatives. Our compliance efforts may not be successful and may divert management’s attention from other business concerns and harm our business, financial condition, and results of operations.

Our business could also be adversely impacted if we have deficiencies in our disclosure controls and procedures or internal control over financial reporting as required by SOX.

Pursuant to Section 404 of SOX, we are required to conduct annual assessments on the effectiveness of our internal control over financial reporting. These assessments require disclosure of any material weaknesses identified in our internal control over financial reporting, and we may not always be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective.

During the course of our review and testing, we may identify deficiencies, including material weaknesses, and be unable to remediate them before we must provide required reports. If we identify one or more material weaknesses, stockholders may lose confidence in the reliability of our financial statements and the price of our common stock and Warrants may decline. The existence of a material weakness could also limit our ability to prevent or detect a misstatement of our accounts or disclosures, which could result in a material misstatement of our consolidated financial statements. We cannot guarantee that efforts to remediate a material weakness will ultimately have the intended effects to permit us to timely file our quarterly and annual reports with the SEC, and we may become subject to litigation or investigations by the SEC or other regulatory authorities. If we are unable to timely file periodic reports or maintain compliance with applicable stock exchange listing requirements, stockholders may lose confidence in our financial reporting, the price of our common stock and Warrants may decline, our common stock and Warrants may be subject to delisting, and we may become subject to litigation or investigations by the SEC or other regulatory authorities. We cannot guarantee that the measures we take will be sufficient to avoid potential future deficiencies or material weaknesses.

We may not realize the anticipated benefits of our transactions with a strategic partner in the Republic of Korea and issuance of stock to two individuals who provide services to this partner.

On October 21, 2024, we entered into a series of transactions with a strategic partner in the Republic of Korea, including a $400,000 investment for a 20% equity interest in the partner, loans of approximately $5.6 million to the partner, and receipt a warrant to purchase an additional 20% equity interest in the partner. See Note 11 of our audited financial statements included in this Report for more information. We cannot guarantee that we will receive amounts owed by the partner on time or at all.

Additionally, in connection with this series of transactions, we issued shares of common stock to two individuals who provide services to the partner to incentivize these individuals to provide services that directly and indirectly benefit us. For example, we are utilizing the partner as the installer for installation of the SK On Line. There can be no assurance that our issuance of shares of common stock to such individuals will provide the desired incentives. If the individuals fail to provide services that directly and indirectly benefit us or the partner prioritizes other customers ahead of us, our business, prospects, results of operations, and financial condition could be harmed.

We maintain cash deposits in excess of federally insured limits. Adverse developments affecting financial institutions, including bank failures, could adversely impact our liquidity and financial performance.

We maintain domestic cash deposits in Federal Deposit Insurance Corporation, or FDIC, insured banks that exceed the FDIC insurance limits. The failure of a bank, or other adverse conditions in the financial or credit markets impacting financial institutions at which we maintain balances, could adversely impact our liquidity and financial performance. Bank failures; events involving limited liquidity, defaults, non-performance, or other adverse developments that affect financial institutions; or concerns or rumors about such events may lead to liquidity constraints. For example, on March 10, 2023, Silicon Valley Bank failed and was taken into receivership by the FDIC. We cannot guarantee that our deposits in excess of the FDIC or other comparable insurance limits will be backstopped by the U.S. or applicable foreign government, or that any bank or financial institution with which we do business will be able to obtain needed liquidity from other banks or government institutions or by acquisition in the event of a failure or liquidity crisis.

Our ability to utilize any net operating losses or tax credit carryforwards to offset taxable income may be subject to certain limitations.

Section 382 of the Internal Revenue Code limits the ability of a corporation that undergoes an “ownership change” to use its pre-change net operating losses to offset future taxable income. An “ownership change” generally means a greater than 50 percentage point change (by value) in a corporation’s equity ownership by certain stockholders over a three-year period. If we have experienced an ownership change at any time since our incorporation, we may be subject to these limitations on our ability to utilize our net operating losses and other tax attributes to offset taxable income or tax liability. In addition, future changes in our stock ownership, which may be outside of our control, may trigger an ownership change.

Changes in tax law or regulations could suspend the use of net operating losses or tax credits, possibly with retroactive effect. As a result, if we earn net taxable income, we could be unable or limited in our ability to use net operating losses and other tax attributes to offset such taxable income, which could result in increased future income tax liabilities. Similar provisions of state tax law may also limit our use of accumulated state tax attributes.

Risks Related to Legal and Regulatory Compliance

We have been, and may in the future be, subject to lawsuits, regulatory actions, or government investigations and inquiries which could lead us to incur significant costs or harm our reputation.

From time to time, we have been, and may become involved in significant litigation, regulatory actions, or government investigations and inquiries as well as legal proceedings and investigations arising in the normal course of business, such as commercial or contractual disputes; indemnity or warranty claims; disputes with potential customers, former employees, and suppliers; intellectual property matters; personal injury claims; environmental issues; tax matters; and employment matters. For example, on December 3, 2024, two purported stockholders filed a putative class action against the former officers and directors of Decarbonization Plus Acquisition Corporation III (“DCRC”), including Erik Anderson; Riverstone Holdings, LLC; and related sponsors and entities (the “Hamilton Defendants”). The Hamilton Defendants have demanded indemnification and advancement of defense costs from us, and we could be liable for the legal fees, defense costs, judgments, and/or settlement fees incurred by certain of the Hamilton Defendants. See Note 14 of our audited financial statements included in this Report for more information. Further, if we are successful in our commercialization efforts, we may become subject to product liability claims if our products do not perform as expected or malfunction.

The defense of lawsuits, regulatory actions, or government investigations and inquiries may divert our management’s attention, and we may incur significant expenses in addressing these matters. In the future, we may be required to pay damages or settlements or become subject to injunctions or other equitable remedies, and such claims or liabilities may not be covered by our insurance or by any rights of indemnity or contribution that we have against others. Although we maintain insurance in amounts we believe to be adequate, we may incur claims or liabilities for which we are not insured or that exceed the amount of our insurance coverage. The outcome of litigation, regulatory actions, and government investigations and inquiries is often difficult to predict, and future litigation, regulatory actions, or government investigations and inquiries could have a material adverse effect on our business, prospects, results of operations, and financial condition. Additionally, even if unsuccessful, a lawsuit, regulatory action, or government investigation could generate substantial negative publicity about our technology and business, inhibit commercialization of our products, and impede our ability to secure additional insurance coverage on commercially acceptable terms or at reasonable costs, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We are subject to substantial regulation, and changes to, or failure by us to comply with, these regulations could have a material adverse effect on our business, prospects, results of operations, and financial condition.

Our technology is subject to substantial regulation under international, federal, state, and local laws, including export control laws and other trade regulations, and we incur significant costs in complying with these regulations as we develop and work to commercialize our technology. The U.S. government has made and continues to make significant changes in U.S. trade policy and has taken certain actions that could adversely impact U.S. trade, including imposing tariffs on certain goods imported into the United States, increasing scrutiny on foreign direct investment, and modifying export control laws applicable to certain technologies. In retaliation, other countries have implemented, and continue to evaluate, additional trade controls on a wide range of U.S. products and companies. Sustained uncertainty about, or worsening of, current global economic conditions and further escalation of trade tensions between the United States and its trading partners could result in a global economic slowdown and changes to global trade. Compliance with, and monitoring of, applicable regulations may be difficult, time-consuming, and costly. The nature and extent of any changes in regulations, and their impact on our business, may be unpredictable, and certain of our competitors may be better suited to withstand or react to these changes. Any changes in the laws and regulations to which we or our partners, contractors,

suppliers, or customers are subject, or any changes in enforcement, administration, or interpretation of such laws or regulations, could interfere have a material adverse effect on our business, prospects, results of operations, and financial condition.

We are also subject to laws affecting our operations outside of the United States, including anti-bribery laws, anti-corruption laws, anti-money laundering, and export control laws. For example, our products—including our cells and related technology—are or may in the future be subject to trade and export control laws and regulations in the United States and other jurisdictions where we do business. As a result, an export license may be required to export or re-export our products and technology to certain countries or end-users or for certain end-uses or such export, re-export, or end uses may be prohibited. Obtaining the necessary export license for a particular sale or offering may not be possible or may be time-consuming and may result in the delay or loss of sales opportunities. Additionally, the FCPA prohibits bribery of foreign public officials, government employees, and political parties and requires public companies in the United States to keep books and records that accurately and fairly reflect their transactions. We may leverage third parties to sell our products and conduct our business abroad, and we or such third parties may interact with officials and employees of government agencies or state-owned or -affiliated entities. Regulators in the United States and a number of other countries have expanded their focus on enforcement of anti-bribery, anti-corruption, and export control laws in recent years. While we have implemented policies and procedures designed to ensure compliance by us and our personnel with the FCPA and other applicable anti-bribery, anti-corruption, anti-money laundering, and export control laws, such policies and procedures may not be effective in all instances to prevent violations. Any determination that we have violated these laws could subject us to, among other things, civil and criminal penalties, significant fines, profit disgorgement, injunctions on future conduct, securities litigation, suspension or disbarment from government contracts, and loss of export privileges, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition. Responding to any investigation or action may also divert our management’s attention, and we may incur significant expenses in defending an investigation or action.

Additionally, we and our partners, contractors, suppliers, and customers are subject to numerous international, federal, state, and local environmental health and safety laws and regulations, including those pertaining to management, storage, transportation and disposal of chemicals and wastes; emissions and contamination; and land use, fire code, and zoning. These laws and regulations may require us or our partners, contractors, suppliers, or customers to obtain permits; comply with procedures or restrictions; or incur significant capital, operating, and other costs associated with compliance. For example, our manufacturing process creates regulated air emissions, and we are required to utilize emissions control technology as a result. Our facilities are also subject to environmental permitting requirements, and permitting agencies with discretionary authority may refuse to issue required permits or impose costly permit conditions. Such actions could increase the cost, or lengthen the timeline, of developing additional manufacturing facilities. Future changes in permitted uses or conflicts with non-governmental organizations regarding the use of land for our manufacturing facilities could delay or prevent us from building additional research and development and manufacturing facilities, which could have a material adverse effect on our business, prospects, results of operations, and financial condition. Further, we rely on third-party contractors to ensure compliance with certain laws and regulations, including those relating to the disposal of wastes. If we are unable to secure contractors for key supply chain and disposal services, we could incur increased costs for compliance with environmental health and safety laws and regulations. Any determination that we or our contractors have violated these laws and regulations could subject us to, among other things, civil and criminal penalties, other liabilities under such laws and regulations, and liabilities for any impacts to human health or natural resources, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

We may be adversely impacted by a disruption or failure of our information technology infrastructure, data security breach, or failure to comply with privacy laws.

Our information technology infrastructure is critically important to our business operations. We rely heavily on a host of computer software and hardware systems, including our financial, accounting, and other data processing systems and the systems of third-party service providers. These information technology systems, many of which are managed by third parties or used in connection with shared service centers, may be susceptible to damage, disruptions, or shutdowns due to factors outside of our control, such as failures during the process of upgrading or replacing software, databases, or components thereof; maintenance or security issues or errors; issues with migration of applications to the “cloud;” power outages; hardware or software failures; cyberattacks and other cyber incidents; telecommunication failures; denial of service; user errors; or natural disasters, terrorist attacks, or other catastrophic events. Some of our information technology systems are not fully redundant, and our disaster recovery planning cannot account for all eventualities.

We and our third-party service providers face various security threats on a regular basis, including ongoing cybersecurity threats to and attacks on our and their information technology infrastructure. Cyberattack techniques change often, may not immediately be recognized, and can originate from a wide variety of sources. There has been an increase in the frequency, sophistication, and ingenuity of the data security threats we and our service providers face. We have experienced threats to our data and systems, and existing measures may not prevent or limit the impact of a future incident. Any unauthorized access to or acquisition of data belonging to us or our partners, contractors, suppliers, customers, or employees could result in loss or theft of confidential

information or intellectual property, financial loss or misappropriation of funds, a disruption of our business, damage to our reputation and competitive position, and exposure to regulatory intervention and fines, and other liability, any one of which could have a material adverse effect on our business, prospects, results of operations, and financial condition. Additionally, if our partners, contractors, suppliers, and customers experience a breach or system failure, their business could be disrupted, which could result in a disruption in our supply chain or our research and development activities.

We incur significant costs in building and maintaining our information technology infrastructure; protecting against or remediating breaches, incidents, and disruptions; and monitoring and complying with evolving and complex data privacy regulations, which costs may increase over time. We are subject to a variety of laws and regulations regarding privacy, data protection, and data security, and many jurisdictions require companies to notify individuals, regulatory authorities, and others of security breaches involving certain types of data. We may expend significant resources to notify third parties of a breach, and our insurance coverage may not be sufficient to cover claims or liabilities related to a breach or incident. Further, we may be unable to comply with changes in data privacy regulations in the necessary timeframe or at reasonable cost, and any failure or alleged or perceived failure to comply with applicable data privacy regulations could result in regulatory investigations and proceedings, fines and other liability, and damage to our reputation.

Changes in relevant tax laws or regulations, an adverse interpretation of these items by tax authorities, or changes to our obligations as a result of expanded business operations could adversely impact our effective tax rate and tax liability.

We are subject to income, withholding, and other tax obligations in the United States and the Republic of Korea and may become subject to taxation in additional international, state, and local jurisdictions with respect to income, operations, and subsidiaries related to those jurisdictions. Our future effective tax rates may fluctuate widely. Our effective tax rate in a given financial reporting period may be materially impacted by a variety of factors, such as the composition of operating income by tax jurisdiction; changes in deferred tax assets and liabilities, application of accounting and tax standard, and our pre-tax operating results; and new or revised tax legislation.

Additionally, we record tax expense based on our estimates of future payments, which may include reserves for uncertain tax positions in multiple tax jurisdictions, and valuation allowances related to certain net deferred tax assets. At any one time, many tax years may be subject to audit or examination by various taxing jurisdictions, and the results of these audits, examinations, and negotiations with taxing authorities may affect the ultimate settlement of these issues. Increases in our effective tax rate and tax liability could have a material adverse effect on our business, prospects, results of operations, and financial condition.

Risks Related to our Common Stock and the Warrants

The price of our common stock and Warrants could be adversely impacted by sales of substantial amounts of our common stock or Warrants in the public market or the perception that such sales could occur.

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 price of our common stock and Warrants.

We have registered shares reserved for future issuance under our equity incentive compensation plans. Subject to the satisfaction of applicable vesting restrictions, the shares issued thereunder will be available for immediate resale in the public market.

We may not realize the anticipated benefits of our stock repurchase program, and any failure to repurchase shares of our common stock may adversely impact the price of our common stock.

On January 23, 2024, we announced that our Board approved a stock repurchase program authorizing us to purchase up to $50 million of our outstanding common stock. Under the repurchase program, we may purchase shares of our common stock from time to time on the open market, in unsolicited negotiated transactions, or in any manner that complies with the provisions of Rule 10b-18 of the Exchange Act. The repurchase program expires December 31, 2025. As of December 31, 2024, we have repurchased approximately $9.07 million of our common stock under the repurchase program. The timing and amount of any future purchases under the repurchase program will depend on a number of factors, such as the price of our common stock, economic and market conditions, and corporate and regulatory requirements. If we do not purchase the full amount of shares of our common stock authorized under the repurchase program, our reputation, investor confidence, and the price of our common stock may be adversely impacted.

The existence of the repurchase program could cause the price of our common stock to be higher than it otherwise would be and potentially reduce the market liquidity for our common stock. Further, we cannot guarantee that any purchases under the

repurchase program will enhance long-term stockholder value. For example, the price of our common stock may decline below the levels at which we purchase such shares, and short-term fluctuations in the price of our common stock could reduce the effectiveness of the repurchase program. Purchasing shares of our common stock under the repurchase program will also reduce the amount of cash we have available to fund capital expenditures, investments in strategic initiatives, other operating requirements, and further share repurchases, and we may fail to realize the anticipated benefits of the repurchase program.

If securities or industry analysts do not publish, or publish inaccurate or unfavorable, research about us, our business, or our market, or if they adversely change their recommendations regarding our common stock, the price and trading volume of our common stock and Warrants could decline.

The trading market for our common stock and Warrants is influenced by the research and reports that industry or securities analysts may publish about us, our business, our market, or our competitors. If any of these analysts adversely change their recommendation regarding our common stock, or provide more favorable relative recommendations about our competitors, the price of our common stock and Warrants could decline. If any of these analysts cease coverage or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause the price or trading volume of our common stock and Warrants to decline.

The issuance of additional shares of common stock under our equity incentive compensation plans or employee stock purchase plan or shares of preferred stock would dilute the interest of our stockholders and may present other risks.

We may issue a substantial number of additional shares of common stock under our equity incentive compensation plans or employee stock purchase plan and we may also issue preferred stock. The issuance of additional shares of common stock or shares of preferred stock:

Delaware law and provisions in our second amended and restated certificate of incorporation (our “Second A&R Charter”) and amended and restated bylaws (our “Bylaws”) might delay, discourage, or prevent a change in control of the Company or changes in our management, thereby depressing the price of our common stock and Warrants.

We are a Delaware corporation, and the anti-takeover provisions of the Delaware General Corporation Law (“DGCL”) may discourage, delay, or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, provisions of our Second A&R Charter and Bylaws may make the acquisition of us more difficult, deter hostile takeovers, or delay or prevent changes in our management. Among other things, these provisions:

Our Bylaws designate the Court of Chancery of the State of Delaware as the exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or agents.

Our Bylaws provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state court in Delaware or the federal district court for the District of Delaware) shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of Solid Power, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, stockholder, officer or other employee of Solid Power to us or our stockholders, (iii) any action arising pursuant to any provision of the DGCL or our Second A&R Charter or Bylaws (as either may be amended from time to time), or (iv) any action asserting a claim governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party does not consent to the personal jurisdiction of such court within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than such court or for which such court does not have subject matter jurisdiction.

In addition, our Bylaws provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the “Securities Act”), against any person in connection with any offering of our securities, including, without limitation and for the avoidance of doubt, any auditor, underwriter, expert, control person, or other defendant. Pursuant to the Exchange Act, claims arising thereunder must be brought in federal district courts of the United States of America.

The choice of forum provision in our Bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees, or agents, which may discourage lawsuits with respect to such claims. However, our stockholders will not be deemed to have waived (and cannot waive) our compliance with federal securities laws and the rules and regulations thereunder. If a court were to find the choice of forum provision in our Bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material adverse effect on our business, prospects, results of operations, and financial condition.

There can be no assurance that the our publicly-traded warrants (the “Public Warrants”) or warrants sold in a private placement as part of our initial public offering or acquired through a conversion of a working capital loan (the “Private Placement Warrants” and, together with the Public Warrants, the “Warrants”) will ever be in the money, and they may expire worthless.

The exercise price for the Warrants is $11.50 per share of common stock. There can be no assurance that the Warrants will ever be in the money prior to their expiration, and as such, the Warrants may expire worthless.

We may amend the terms of the Warrants in a manner that may be adverse to holders with the approval of the holders of at least 50% of the then-outstanding Public Warrants (or, if applicable, 65% of the then-outstanding Public Warrants and 65% of the then-outstanding Private Placement Warrants, voting as separate classes).

Our Warrants were issued in registered form under our warrant agreement with Continental Stock Transfer & Trust Company which provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then-outstanding Public Warrants to make any other changes. However, if an amendment would adversely and differently affect either the Public Warrants or Private Placement Warrants, the approval of 65% of the then-outstanding Public Warrants and 65% of the then-outstanding Private Placement Warrants, voting as

separate classes, is required. Accordingly, we may amend the terms of the Warrants in a manner adverse to a holder if holders of at least 50% of the then-outstanding Public Warrants (or, if applicable, 65% of the then-outstanding Public Warrants and 65% of the then-outstanding Private Placement Warrants, voting as separate classes) approve of such amendment. Although our ability to amend the terms of the Warrants with approval of the holders of at least 50% of the then-outstanding Public Warrants (or, if applicable, 65% of the then-outstanding Public Warrants and 65% of the then-outstanding Private Placement Warrants, voting as separate classes) is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Warrants, convert the Warrants into cash or stock (at a ratio different than initially provided), shorten the exercise period, or decrease the number of shares of our common stock purchasable upon exercise of a Warrant.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the consolidated financial statements and related notes thereto included elsewhere in this Report. The following discussion contains forward-looking statements that reflect future plans, estimates, beliefs, and expected performance. For additional discussion, see “Cautionary Note Regarding Forward-Looking Statements” above. The forward-looking statements are dependent upon events, risks, and uncertainties that may be outside of our control. Our actual results could differ materially from those

discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed elsewhere in this Report under “Part I, Item 1A. Risk Factors,” as such descriptions may be updated or amended in future filings we make with the SEC. Unless indicated otherwise, the following discussion and analysis of financial condition and results of operations should be read in conjunction with the consolidated statements and notes thereto in this Report. We do not undertake, and expressly disclaim, any obligation to publicly update any forward-looking statements, whether as a result of new information, new developments or otherwise, except to the extent that such disclosure is required by applicable law.

Overview

Solid Power is a U.S.-based leader in solid-state battery technology and manufacturing processes. Our core technology is a sulfide-based solid electrolyte material, which replaces the liquid or gel electrolyte used in traditional lithium-ion battery cells. We believe our electrolyte technology has the potential to enable a step-change improvement in battery cell performance beyond what is currently achievable in conventional lithium-ion battery cells, including improved energy density, battery life, and safety performance. We are currently targeting the EV market due to the size and perceived demand for next generation battery technology but believe our technologies can have a broader application as they mature.

Key Factors Affecting Operating Results

We are a research and development-stage company and have not generated significant revenue through the sale of our electrolyte or licensing of our cell designs. Our ability to commercialize our products depends on several factors that present significant opportunities but also pose material risks and challenges, including those discussed in the “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” sections of this Report, which are incorporated by reference.

Prior to reaching commercialization, we must improve our products to ensure they meet the performance requirements of our customers. We also will have to continue to negotiate commercial agreements with our customers on terms and conditions that are mutually acceptable. To satisfy anticipated demand, we will need to scale production of our electrolyte. All of these factors will take time and affect our operating results. Since many factors are difficult to quantify, our actual operating results may be different than currently anticipated.

Revenue generated to date has primarily come from performance on research and development licensing agreements and government contracts. We will need to continue to deploy substantial capital to expand our production capabilities and engage in research and development programs. We also expect to continue to incur administrative expenses as a publicly traded company.

In addition to meeting our development goals, commercialization and future growth and demand for our products are highly dependent upon consumers adopting EVs. The market for new energy vehicles is still rapidly evolving due to emerging technologies, competitive pricing, government regulation and industry standards, and changing consumer demands and behaviors.

Basis of Presentation

We currently conduct our business through one operating segment. As a research and development company with no commercial operations, our activities were conducted primarily in the United States as well as Republic of Korea. Our historical results are reported under U.S. generally accepted accounting principles (“GAAP”) and in U.S. dollars.

Results of Operations

During the year ended December 31, 2024, we increased capital and operational investments centered on expanding our electrolyte capabilities and advancing our cell designs. Our most significant capital investment in 2024 was the EIC, which is designed to develop, improve, and test electrolyte manufacturing processes. Our operational investments were focused on the strategic enhancement of our research and development workforce, strengthening our presence in the Republic of Korea, as well as efforts to improve electrolyte and cell performance.

Revenue

We have entered into various collaborative arrangements for research and development efforts related to our technologies. In 2024, we generated revenue of $20.1 million, which represented a $2.7 million, or 16%, increase compared to our 2023 revenue of $17.4 million. This increase was driven primarily by our performance on the SK On Agreements, with strong execution on the line installation agreement and completion of key steps in the transfer of our technology, which together accounted for $11.8 million of our 2024 revenue. We intend to continue executing on the SK On Agreements and anticipate an increase in revenue in 2025 as we achieve

milestones under the SK On Agreements. The decrease in government revenue in 2024 was related to the completion of certain government grants in 2023 and the timing of entry into the Assistance Agreement with DOE. While there can be no assurance that we will continue to receive funding under our government contracts and grants in the amounts we expect or at all, government revenue may increase in 2025 compared to 2024 as we execute on the Assistance Agreement and begin facility engineering and construction of a pilot electrolyte line using a continuous manufacturing process.

​

Operating Expenses

​

Our operating expenses consist primarily of research and development costs focused on improving the performance of our electrolyte and cell designs. In 2024, operating expenses were $125.5 million, an increase of $17.5 million compared to our operating expenses of $108.0 million in 2023. This increase was largely attributable to a 30% increase in electrolyte production in 2024 compared to 2023. This resulted in a corresponding increase to our production costs, such as materials, lab supplies, and hazardous waste removal. In 2025, we expect production costs to be consistent with 2024. Although we anticipate increasing electrolyte production in 2025, we intend to offset the increase in production cost with more favorable pricing on input materials and hazardous waste disposal. The increase in operating expenses in 2024 also resulted from equipment purchases made in the performance of the SK On Agreements, which accounted for $8.2 million of our operating expenses in 2024. In 2025, we expect expenses associated with the execution of the SK On Agreements to increase in correlation with an increase in revenue as we achieve the next milestones under the SK On Agreements. Additionally, we had an increase in costs related to scaling our operations in the United States and the Republic of Korea in 2024. Overall, we expect operating expenses to increase in 2025 compared to 2024 as we continue to focus on our collaborative arrangements and research and development efforts.

​

Nonoperating Income and Expense

​

Our nonoperating income and expense consists of interest income earned on our investments, the non-cash change in our fair value of our warrant liabilities, and non-recurring expense items. In 2024, nonoperating income and expense was $10.1 million, a decrease of $15.0 million compared to our nonoperating income and expense of $25.1 million in 2023. This decrease was driven in part by the reduced cash balance of our investments in 2024, which resulted in a lower actual book return of our investments. As a result, interest income in 2024 was $17.7 million, a decrease of $2.6 million compared to interest income of $20.3 million in 2023. The decrease in nonoperating income and expense was also due to a change in the fair value of our warrant liabilities that drove a year-over-year increase in expense of $9.4 million as well as a $2.0 million non-cash loss on the disposal of assets.
​

Liquidity and Capital Resources

Sources of Liquidity

The sale of equity has historically been our primary source of cash, with a smaller portion of cash coming from achievement of performance milestones under agreements with our partners and our government contracts.

As of December 31, 2024 and 2023, we had total liquidity as set forth below:

​

As of December 31, 2024, contract receivables were $1.4 million, deferred revenue was $3.2 million, and total current liabilities were $20.0 million. As of December 31, 2023, contract receivables were $1.6 million, deferred revenue and deferred revenue from related parties was $0.8 million, and total current liabilities were $15.9 million.

​

Short-Term Liquidity Requirements

Our short-term liquidity requirements include operating and capital expenses needed to further our research and development programs and to install our continuous electrolyte production line. We anticipate that our most significant capital expenditures in 2025 will relate to facility engineering and construction of a pilot electrolyte line using a continuous manufacturing process and improvements to our cell development capabilities.

We anticipate our total combined capital expenditures and cash flow from operations for 2025 will be between $100 million and $120 million, excluding any benefit from the Assistance Agreement. We expect to fund our short-term liquidity requirements through our cash on hand and other liquid assets.

Long-Term Liquidity Requirements

We believe that our cash on hand is sufficient to meet our operating cash needs and working capital and capital expenditure requirements for a period of at least the next 12 months. Longer-term, we believe we have adequate liquidity to support our operations until we generate adequate cash flows from electrolyte sales and/or licensing activities or we raise additional capital. We also believe that we have adequate cash on hand for our stock repurchase program should we choose to execute additional share repurchases.

We may require additional liquidity sources if there are material changes to our business conditions or other developments, including changes to our operating plan; development progress or delays; negotiations with OEMs, cell manufacturers, or other customers; market adoption of EVs; supply chain challenges; competitive pressures; and inflation. To the extent that our resources are insufficient to satisfy our cash requirements, we may need to seek additional equity or debt financing. We also may opportunistically seek to enhance our liquidity through equity or debt financing, if such financing becomes available to us on terms that we consider favorable. If financing is not available, or if the terms of financing are less desirable than we expect, we may be forced to take actions to reduce our capital or operating expenditures, which may adversely affect our development, business, operating results, financial condition and prospects.

Stock Repurchase Program

On January 23, 2024, we announced that our Board approved a stock repurchase program authorizing us to purchase up to $50 million of our outstanding common stock. Under the stock repurchase program, we may purchase shares of our common stock from time to time until the repurchase program expires on December 31, 2025. The shares of common stock may be purchased on the open market, in unsolicited negotiated transactions, or in any manner that complies with the provisions of Rule 10b-18 of the Exchange Act. Management’s decision to repurchase shares will depend on a number of factors, such as the price of our common stock, economic and market conditions, and corporate and regulatory requirements. During the year ended December 31, 2024, we repurchased 5,704,401 shares of common stock at an average cost of $1.59 per share for an aggregate cost of approximately $9.07 million.

Cash Flows

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

​

Cash used in operating activities:

Cash used in operating activities increased $5.6 million from 2023 to 2024 primarily due to increased research and development costs related to improving our electrolyte and cell designs and increased electrolyte production. The increase in cash used in operating activities was also due to increased direct equipment costs associated with execution of the SK On Agreements, with a portion of these costs reflected in Prepaid expenses and other current assets in the Consolidated Balance Sheets as of December 31, 2024. The increase in cash used in operating activities was partially offset by increased cash received from customers, with $21.1 million of cash received from customers in 2024 compared to $12.6 million of cash received from customers in 2023. 

Cash provided by investing activities:

Cash provided by investing activities increased $21.7 million from 2023 to 2024 primarily due to increased proceeds from purchases and sales of available-for-sale securities, which provided $86.8 million of proceeds in 2024 compared to $77.6 million of proceeds in 2023. The increase in cash provided by investing activities was partially offset by capital expenditures for construction of the EIC in 2024 and cash used for our investment in a strategic partner in the Republic of Korea.

Cash provided by (used in) financing activities:

Cash used in financing activities increased $9.6 million from 2023 to 2024 primarily as a result of cash utilized for the repurchase of $9.07 million of our common stock under the stock repurchase program.

Off-Balance Sheet Arrangements

We are not a party to any off-balance sheet arrangements, as defined under SEC rules.

Critical Accounting Estimates

Our discussion and analysis of financial condition and results of operations are based on our financial statements included elsewhere or incorporated by reference in this Report. The preparation of our financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. We base our estimates on past experience, technical analysis and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may differ from those estimates.

Our critical accounting estimates are those that materially affect our financial statements and involve difficult, subjective, or complex judgments by management. A thorough understanding of these critical accounting estimates is essential when reviewing our financial statements. We believe that the critical accounting estimates listed below involve the most difficult management decisions because they require the use of significant estimates and assumptions as described above.

(the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive loss, stockholders' equity and cash flows for each of the two years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

​

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

​

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

​

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
