## PART I

## Item 1. Business

## Overview

Solid Power is developing solid state battery technologies to enable the next generation of rechargeable batteries for the fast-growing EV and other markets.

Our core technology is our proprietary sulfide-based solid electrolyte material, which replaces the liquid or gel electrolyte used in conventional lithium-ion batteries. We believe that our electrolyte material can enable extended driving range, longer battery life, improved safety, and lower costs compared to conventional lithium-ion.

We also are designing and developing solid state cells that utilize our electrolyte in the cathode, anode, and separator layers. Our most mature cell design uses a silicon anode, NMC cathode, and solid separator. We are in earlier research development on additional cell designs, including lithium-metal, an anode-less design and a cell that replaces the nickel and cobalt in the cathode with earth abundant materials.

We currently produce 0.2 Ah, 2 Ah, 20 Ah, and EV cells on two pilot lines using established manufacturing processes. To support testing requirements of our partners and further refinement of our cell design, we will continue to produce 2 Ah, 20 Ah and EV cells during 2023. Longer-term, we expect to use our pilot lines to further our research and development activities.

We have partnered with industry leaders, including Ford, BMW, and SK On. We are working closely with each of these partners to refine and validate our cell designs and electrolyte material with the ultimate goal to commercialize our technologies.

The products we currently make are in the development stage and require continued development and validation before we can commercialize either our electrolyte or cell technology. For more information, see “Risk Factors — Risks Related to Development and Commercialization.”

## Business Model

Our business model currently has two strategic elements:

• Selling our electrolyte material.

• Licensing our cell designs and manufacturing processes.

We believe this business model distinguishes us from many of our competitors that seek to become commercial battery manufacturers. Ultimately, we endeavor to be a leading producer and distributor of sulfide-based solid electrolyte material for powering both EVs and other applications. Since we do not intend to commercially produce battery cells, we expect to invest significantly less than other development-stage battery companies that plan to commercially manufacture their own cell designs and construct their own battery production facilities.

## Benefits of Our Technologies

## Driving Range

We have designed our cells with the expectation they will have higher energy compared to traditional lithium-ion battery cells. We expect higher energy cells to provide OEMs with the flexibility to balance cost and driving range when designing their EVs.

## Battery Life

We expect our electrolyte will improve high temperature stability of our cells compared to conventional lithium-ion technology. This could allow for the removal or reduction of battery pack cooling systems. A potential additional benefit could be a longer life of the cell and less permanent degradation in battery capacity at higher temperatures.



## Safety

We believe solid electrolytes can improve the safety of battery cells because conventional lithium-ion batteries use a liquid or gel electrolyte that is highly flammable and volatile under certain circumstances. Our solid electrolyte has a much higher ignition point than traditional liquid or gel electrolytes, which means it has the potential to be safer than conventional lithium-ion.

## Cost

We anticipate cell designs incorporating our electrolyte will cost less to produce than conventional lithium-ion. This is enabled in part because our cell designs can be manufactured with existing industry-standard manufacturing processes and equipment. The processes we have adopted have the potential to reduce the time, cost and space needed to manufacture cells. Additionally, we are in the early stages of developing a cell that replaces the nickel and cobalt in the cathode with earth abundant materials. If we are able to successfully develop this technology, it could cut cathode costs by up to 90%.

## 2022 Highlights

Fiscal year 2022 was an important and successful year for Solid Power during which we installed critical infrastructure, enhanced our electrolyte and cell development capabilities, expanded our relationship with BMW, and added critical team members. Our key 2022 highlights are below and discussed elsewhere in this Business section:

Electrolyte facility. We began construction of a pilot electrolyte production line. We expect this facility to come online in the first quarter of 2023. We anticipate this facility will be capable of producing up to 30 metric tons of electrolyte per year, which we expect to be sufficient to support demand until commercialization.

Installation of the EV line. We successfully installed the EV line and began producing our first EV cells. We expect to utilize the EV line for the automotive qualification process and for vehicle demonstration purposes. The EV line is designed to ultimately produce up to 300 EV cells a week.

Delivery of 20 Ah cells to our partners. We were able to successfully produce and deliver hundreds of 20 Ah cells to our automotive partners and third-party testing agencies as part of our JDA programs. In addition, our 20 Ah cells recently received UNDOT 38.3 certification, which is required to demonstrate the safety of our cells during shipping.

BMW R&D technology transfer. We entered into our first research and development-only license agreement with BMW, which will allow BMW to replicate our pilot cell lines at their own facilities and develop cells based on our designs.

## Our Growth and Research & Development Strategy

Our research and development activities focus on making continual improvements to our electrolyte and cell technologies with the ultimate goal of commercializing technologies that outperform conventional lithium-ion. While we believe our goals are achievable, and our roadmap to hitting those goals is reasonable, as with any company that is developing novel technology, our strategy, forecasts, and timetables are subject to change. For more information, see “Risk Factors — Risks Related to Development and Commercialization.” Our research and development activities are currently focused on the following initiatives:

## Electrolyte Development

As we continue to scale our electrolyte capabilities, we are focused on the following:

Expand sulfide-based solid electrolyte production. We currently produce approximately 2 metric tons of electrolyte per year. After we initiate electrolyte production on our new line, we expect to have the capacity to produce approximately 30 metric tons of electrolyte per year. We intend to scale our electrolyte capacity based on market adoption and the electrolyte needs of our partners and other potential customers.



Continue development of electrolyte materials and performance. Our first generation of electrolyte is primarily used in cells we manufacture. We have started producing limited volumes of our second-generation electrolyte and will increase production volumes based on external and internal demand. Our second-generation electrolyte has demonstrated improved performance characteristics compared to our first-generation electrolyte, especially with respect to ionic conductivity. Better ionic conductivity can improve charge rates and cell performance. We are continuously working to improve the performance and anticipated cost of our electrolyte materials and to develop new materials.

Increase lithium sulfide production. We currently take a multi-pronged approach to secure the Li2S needed to make our electrolyte. We currently source Li2S from leading lithium and chemical companies globally. While we expect Li2S production to increase significantly with commercialization of sulfide-based cells, we are also developing a low-cost Li2S production method to address potential supply chain risks.

## Cell Development

As we continue to develop our cell technology, we are focused on the following:

Drive cell performance improvements to meet OEM specifications. We have worked closely with each of our partners to develop a roadmap to meet their ultimate commercial performance targets. While we believe our roadmaps are achievable, we will need to continue to improve our overall cell performance, including energy density, pressure, cycle life, low temperature performance, and safety. We recently began safety testing of our 20 Ah cells. The results of certain safety tests were inconsistent with the results from the same tests on our 2 Ah cells. A key objective for 2023 is to develop solutions to match the results of the 2 Ah cells with our 20 Ah cells. As we work to formally enter automotive qualification with our EV cell, we will continue to refine our cell designs and manufacturing processes to improve the performance of our cells.

Refine manufacturing techniques. As we moved from producing 2 Ah cells to the larger 20 Ah cells, our manufacturing yields were lower than we anticipated. We have implemented cell design improvements that better match the manufacturing capabilities of our pilot lines, which we expect will result in continued yield improvements.

Invest in next-gen battery cell innovations. In January 2023, we were awarded a $5.6 million research grant from the U.S. Department of Energy ARPA-E group to continue our development of nickel- and cobalt-free battery cells. This generation of cells, which is enabled by our electrolyte technology, could completely remove nickel and cobalt from the cathode, which can represent up to 90% of current cathode costs. Our research and development teams also are working on lithium metal cells and a cell that is anode free. Each of these technologies are significantly earlier in development than our current EV cell.



## The Path to Automotive Qualification

Our cell technology must meet demanding OEM standards before they can be incorporated into EVs. Our plan follows a staged product development approach guided by APQP. The following table highlights the stages and standards we believe will need to be met for our technology to be integrated into EVs:

<table><tr><td>Category</td><td>Stage</td><td>Standard</td><td>Solid Power Cell Format</td></tr><tr><td>Pre-A sample</td><td>Proof of concept</td><td>1. Produce cells to demonstrate functionality towards basic product requirements.</td><td>0.2 Ah, 2 Ah, 20 Ah, and EV</td></tr><tr><td rowspan="2">A-sample</td><td rowspan="2">Cell concept validation</td><td>1.

We are currently producing Pre-A sample 20 Ah and EV cells. We are focused on demonstrating that our Pre-A sample cells will meet our partner’s basic requirements for vehicle integration. A major 2023 goal is to produce EV cells to formally enter A-sample testing.

Once we formally begin the automotive qualification process with an A-sample, we expect to work closely with our partners to refine our cell designs to meet their performance requirements. We anticipate that we will need to produce multiple A-sample variations before finalizing the design and progressing to B-sample. One or more of our partners may elect to produce their own B-sample cells to customize the cells for their specific needs or to have more supply chain control. After we enter A-sample, we intend to work with each of our partners to determine the preferred approach for B-sample production.

Due to the requirement that C-sample and D-sample cells are produced on production equipment rather than pilot equipment, we intend to partner with OEMs and/or top tier cell manufacturers for this stage of development rather than produce C-sample or D-sample cells at our facilities.

## Partnerships

Since we do not contemplate becoming a mass commercial cell producer, one of our key goals is to establish and expand partnerships with OEMs and cell manufacturers. Our joint development agreements with BMW, Ford, and SK On are non-exclusive. This allows us the ability to pursue additional relationships with other OEMs or cell manufacturers. We intend to focus on establishing and expanding our partnership relationships with additional OEMs and cell manufacturers through both our cell designs and electrolyte material. The ultimate commercial success of our partnership relationships is subject to various risks and uncertainties. For more information, see “Risk Factors — Risks Related to Development and Commercialization.” The following sets forth the material terms of our JDAs with each of BMW, Ford, and SK On.

## 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’s participation in the Series B Financing and with the execution of a JDA for EV cells for testing and vehicle integration with BMW.



Generally, the JDA with BMW sets out the framework for collaboration on the research and development and vehicle integration of solid-state battery cells. The JDA requires us to continue our research and development efforts such that our products are capable of being deployed in BMW’s EVs. Though our anticipated timing for achievement of the various milestones and development targets continues to evolve under the JDA, we are currently targeting delivery of EV cells to BMW in 2023. Additionally, the terms of the JDA permit BMW to share in certain intellectual property developed through the research and development efforts required under the JDA. 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 that we will enter into additional agreements with BMW for purchase and pricing of electrolyte materials for integration into cell designs, as well as licensing our cell technology to cell producers. However, the key commercial terms of such additional arrangements have not yet been determined.

During 2022, we amended our JDA with BMW to provide BMW with a research and development-only license to certain of our intellectual property relating to cell manufacturing. The license allows, among other things, for BMW to install a solid-state prototype cell manufacturing line based upon our proprietary information. In consideration of the license and additional development activities under the JDA, BMW agreed to pay us $20 million between December 2022 and June 2024, subject to our achieving certain milestones. Under the amended JDA, and prior to the installation of BMW’s anticipated prototype cell manufacturing line, we expect to engage 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. Finally, we expect to negotiate a non-exclusive short-term electrolyte supply agreement allowing us to supply BMW with our electrolyte material for use in BMW’s cell manufacturing, which is expected to commence in 2024 following commissioning of BMW’s prototype cell manufacturing line.

Pursuant to the BMW Nomination Agreement, BMW Holding has the right to nominate a director for election to our 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 Legacy Solid Power 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.

## Ford Motor Company

We started our relationship with Ford in 2018, when it participated in our Series A-1 equity financing by providing both business plan validation and capital. 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.

Generally, 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 such that our products are capable of being deployed in Ford’s EVs. Though our anticipated timing for achievement of the various milestones and development targets continues to evolve under the JDA, we are currently targeting delivery of EV cells to Ford in 2023. Additionally, the terms of the JDA permit Ford to share in the intellectual property developed through the research and development efforts required under the JDA. 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 that we will enter into additional agreements with Ford for purchase and pricing of electrolyte materials for integration into cell designs, as well as licensing our cell technology to cell producers. However, the key commercial terms of such additional arrangements have not yet been determined.

## SK On

In October 2021, we entered into a non-exclusive JDA with SK On for joint production of our EV cells and, contemporaneously, and in connection with the closing of the business combination, SK On invested 30 million in our company. The JDA contemplates that SK On and Solid Power will collaborate to validate that Solid Power’s cell designs and production processes are scalable and compatible with existing lithium-ion production technology to enable us to deliver pre-commercial cells to our OEM customers as part of the APQP process.

Under the terms of the JDA, we expected that Solid Power would produce B-sample EV cells in 2023 at our headquarters in Louisville, Colorado and SK On would be capable of producing the Solid Power-designed C-sample EV cells in 2024 at its facilities, each as part of the APQP process. However, due to the pace of development by both parties and delayed planned market adoption of



solid-state batteries in general, we do not currently expect to meet those target dates. We are working collectively with SK On in connection with a revised development roadmap and associated expected timing. The terms of the JDA permit SK On to share in the intellectual property developed through the joint production efforts required under the JDA. The JDA also contemplates that Solid Power and SK On will, upon the fulfillment of certain milestones under the JDA, negotiate a commercial agreement, which agreement is expected to cover terms and conditions for the sale of our electrolyte materials and licensing terms for our cell designs, manufacturing techniques, and production practices. We intend to negotiate the commercialization agreement simultaneously with fulfilling our obligations under the JDA for cell production.

## Manufacturing and Supply

We have designed our manufacturing processes to use much of the same equipment currently used in production of conventional lithium-ion battery cells. Since inception, manufacturability has been fundamental to our strategy. This drove the selection of a sulfide-based solid electrolyte solution and our subsequent research and development. We believe that using industry standard production processes and equipment reduces commercialization risk and can allow for rapid deployment of technology among early adopters.

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 need for Li2S to significantly increase upon commercialization of sulfide-based cells, we are taking a two-pronged approach to secure the necessary supply of Li2S: sourcing from multiple global entities and working to develop processes to produce material in-house using novel production methods.

Our cell design is a multi-layered stacked pouch cell, which we manufacture ourselves. We also manufacture our cathode and anode using materials sourced from external suppliers. We source other input materials from both industry leading and emerging suppliers. Our two pilot production lines have successfully produced prototype cells in 0.2 Ah, 2 Ah, 20 Ah, and EV cell form factors.

## 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 invented by us, 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 accelerated our patent application filings in 2022 and are continuing that acceleration in 2023. We regularly file new applications in areas that are enforceable and/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, 2023, we owned or exclusively licensed 13 issued United States patents and 38 pending United States patent applications, 48 non-Untitled States and PCT patents and applications, and two registered United States trademarks. We further protect our intellectual property with non-disclosure agreements for all employees and consultants and material transfer agreements and non-disclosure agreements with third parties.

## Competition

Performance improvements in next-generation battery and EV technologies will contribute to global adoption of EVs. This trend has heightened competition in the industry and increased the risk of potential new entrants, which could negatively impact the success of our business, results of operations or financial condition.

We compete directly with both established and emerging EV battery cell producers and materials suppliers. As we get closer to start-of-production for the next generation of EVs, new and emerging battery technologies could create impediments to our commercial success. Nonetheless, we believe we are well-positioned across the battery cell technology value chain, including material and cell development, production techniques, and our business model. Our prospective competitors include major OEMs and top tier battery producers currently supplying, producing and developing batteries for EVs.

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



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

## Government Regulation and Compliance

Government regulations frequently control how battery cells and their components are stored, transported, used and disposed of. We are subject to regulations governing the proper handling, storage, disposal and transportation of products containing hazardous materials, including federal regulations governing transport of battery cells and state laws relating to recycling and disposal of battery cells.

We are subject to federal and state environmental laws and regulations regarding the handling and disposal of hazardous substances and solid waste. These laws regulate the generation, storage, treatment, transportation, and disposal of solid and hazardous waste and 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 course of ordinary 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.

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. Such laws may include the export administration regulations and similar export control regimes, trade and economic sanctions maintained by the Office of Foreign Asset Control and other similar agencies, foreign direct investment rules and regulations, tariffs and quotas, and other related regulations in jurisdictions in which we operate. In particular, 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-users or 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. Any failure to adequately address these legal obligations could result in civil fines or suspension or loss of our export privileges, any of which could materially adversely affect our business, financial condition, and results of operations.

In addition, our business may be subject to the Foreign Corrupt Practices Act and other anti-corruption, anti-bribery, and anti-money laundering laws and regulations in the jurisdictions in which we have offices or do business, both domestic and abroad. Any failure to adequately comply with any of these obligations, or future changes with respect to any of these legal regimes, could cause us to incur significant costs, including the potential for new overhead costs, fines, sanctions, and third-party claims.

## Human Capital

As of February 1, 2023, we employed 236 full-time employees, based out of our facilities in Louisville, Colorado and Thornton, Colorado. This represents a growth of over 100 employees in the past year. Many of our employees have a technical background or hold advanced engineering and scientific degrees. We are committed to increasing diversity in the workforce and we believe building and maintaining an inclusive and positive culture is important for our success.

We are committed to compensating our employees in a competitive manner. We have taken steps to comply with Colorado’s Equal Pay for Equal Work Act. We offer competitive salaries and benefits, as well as a robust equity compensation plan, all with the intention of attracting and retaining team members capable of making our company a world leader in electrolyte production and solid-state battery development. Our compensation decisions are driven by individual contributions, the overall market, and how critical the role is to our success.



To date, we have not experienced any work stoppages and we consider our relationship with our employees to be good. None of our employees are either represented by a labor union or subject to a collective bargaining agreement.

## 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, financial condition and results of operations 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 may also materially adversely affect our business, prospects, financial condition and results of operations. 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:

- It will be challenging to develop solid-state battery cells capable of production at volume and with acceptable performance, yields and costs. The pace of development in materials science is often not predictable. Delays or failures in accomplishing particular development objectives may postpone or prevent us from generating revenues from the licensing of our battery cell technology or sales of our electrolyte.

- We may not succeed in developing our electrolyte for commercialization or attracting customers. There is currently no commercial market for sulfide-based electrolytes and one may never emerge. Even if sulfide-based electrolytes are commercially adopted, we may not be able to effectively compete in any market. If we are unable to develop and sell commercial levels of electrolyte, it could impair our reputation and prospects materially.

- If our cells or electrolyte fail to perform as expected, our ability to develop, market, and license our technology could be harmed.

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

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

- We may not succeed in developing solid-state battery cells for commercialization under our JDAs within the time parameters specified therein. If we do not meet the milestones in certain JDAs, our partners may terminate them without liability to us. Termination of a JDA by a partner, particularly a key partner like BMW, Ford or SK On, could impair our reputation and prospects materially.

- The non-exclusive nature of our JDAs exposes us to the risk that our partners may elect to pursue other battery cell technologies, which likely would impair our revenue generating ability.



- Our business depends on our ability to manage our relationships with existing and future partners, customers, and suppliers. We may not succeed in managing these business relationships, which could slow our development progress and impair our business prospects.

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

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

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

- If solid-state battery cell technology does not become widely accepted, we may not be successful in generating revenues from the manufacture and sale of our electrolyte.

- The battery cell 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 business prospects among current and future partners and customers.

- We may not succeed in attracting customers during the development stage or for high volume commercial production, and our future growth and success depend on our ability to attract customers.

- We may not be able to accurately estimate the future supply and demand for our cells and/or our electrolyte, which could result in a variety of inefficiencies in our business and hinder our ability to generate revenue. If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience delays.

- We rely heavily on owned and exclusively-licensed intellectual property, which includes patent rights, trade secrets, copyright, trademarks, and know-how. If we are unable to protect and maintain access to these intellectual property rights, our business and competitive position would be harmed.

- We have not performed exhaustive searches or analyses of the intellectual property landscape of the battery industry; therefore, we are unable to guarantee that our technology, or its ultimate integration into EV battery packs, 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 could cause us to incur substantial costs.

- Our business model has yet to be tested and any failure to execute on our strategic plans, including commercialization, would have a material adverse effect on our operating results and business, harm our reputation and could result in substantial liabilities that exceed our resources.

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

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

- Our interim CEO and several of our other executive officers have only limited experience in operating a public company.



- Our expectations and targets regarding the times when we will achieve various technical, pre-production and production-level performance objectives depend in large part upon assumptions, estimates, measurements, testing, analyses and data developed and performed by us, which if incorrect or flawed, could have a material adverse effect on our actual operating results and performance.

- If we are unable to maintain an effective system of internal controls and procedures required by the Sarbanes-Oxley Act, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our stock price, business and operating results.

- We incur significant expenses and administrative burdens as a public company, which could have an adverse effect on our business, financial condition and results of operations.

- Sales of substantial amounts of our common stock in the public markets, or the perception that such sales could occur, could cause the market price of our common stock to drop significantly.

## Risks Related to Development and Commercialization

It will be challenging to develop solid-state battery cells capable of production at volume and with acceptable performance, yields and costs. The pace of development in materials science is often not predictable. Delays or failures in accomplishing particular development objectives may postpone or prevent us from generating revenues from the licensing of our battery cell technology or sales of our electrolyte.

Our business depends on our ability to develop battery cells that outperform the lithium-ion batteries currently prevalent in EVs. We expect to need several additional years of research and development and automotive qualification efforts before our cells will be advanced enough for us to realize material revenue from licensing agreements for our battery cell technology or reach commercial levels of sales of our electrolyte materials. Developing the technology and know-how to produce solid-state battery cells at scale and cost, and which meet the performance requirements for wide adoption by OEMs, is extremely challenging. We must overcome significant hurdles to complete development, validation and automotive qualification of our battery cells prior to being able to license or sell our technology to any customers. Some of the development hurdles that we need to overcome before licensing or selling our solid-state battery cell technology to customers include:

- increasing the volume, yield, reliability and uniformity of our cells and cell components;

• increasing the size and number of layers of our cells;

• developing manufacturing techniques to produce the volume of cells needed for customer applications;

• understanding optimization requirements for high volume manufacturing equipment;

- designing and engineering packaging to ensure adequate cycle life (i.e., the number of charge and discharge cycle that a battery cell can sustain until its capacity falls below 80% of the original capacity);

• reducing cost of production; and

- meeting the rigorous and challenging specifications required by our customers, and ultimately OEMs and cell manufacturers, including but not limited to, battery life, energy density, abuse and safety testing, charge rate, cycle life, stack pressure, and operating temperature.

We have encountered and expect to continue to encounter engineering challenges as we increase the dimensions and throughput of components and cells. For example, after experiencing lower than expected manufacturing yields in 2022, we implemented cell design improvements with the goal of better matching our manufacturing capabilities. To achieve target energy levels, we need to increase the layers and dimensions of our current electrodes, which are enclosed within a single battery package. In order to be commercially viable our cells will need to be capable of being produced at a high yield without compromising performance, and we will have to solve related packaging challenges in a way that is scalable and at an acceptable cost. If we are not



able to overcome these engineering and mechanical hurdles, we may not succeed in licensing our cell technology or selling our electrolytes to customers as needed to continue our business and may result in damage to our business, prospects, financial condition, operating results and brand.

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. Any delay in the development, automotive qualification or third-party manufacturing scale-up would delay our time to generate material revenue. It may also negatively impact end-user relationships, including OEMs. Significant delays in providing licenses to our technology would materially damage our business, prospects, financial condition, operating results and brand.

We may not succeed in developing our electrolyte for commercialization or attracting customers. There is currently no commercial market for sulfide-based electrolytes and one may never emerge. Even if sulfide-based electrolytes are commercially adopted, we may not be able to effectively compete in any market. If we are unable to develop and sell commercial levels of electrolyte, it could impair our reputation and prospects materially.

Our electrolyte is in the development-stage and there is no established market for sulfide-based electrolyte material. Even if we are able to successfully develop our electrolyte, our ability to sell it to customers will depend upon our success in developing battery cells which outperform those of traditional lithium-ion batteries. If battery manufacturers do not adopt sulfide-based cell architectures, we may not be able to find customers to buy our electrolyte. Even if sulfide-based electrolytes are commercially adopted, we may have to compete with established companies that may be better capitalized, have more experienced, can deliver a superior product, or have stronger relationships with their supply chain and customers. Given the importance of future electrolyte sales to our success, if we are unable to successfully sell commercial volumes of electrolyte our business, financial results, and prospects will be materially impacted.

If our cells or electrolyte fail to perform as expected, our ability to develop, market, and license or sell our technology could be harmed.

Our battery cell architecture is inherently complex and incorporates technology and components that have not been used in commercial battery cell production. We anticipate that our research and development efforts will extend in an iterative process even beyond the time at which we initially deliver our cells to OEMs for validation or 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 even after the initial delivery of our cells to OEMs or electrolyte to customers. For instance, we may learn from these validation efforts that our cells contain defects or errors that cause the cells not to perform as expected or 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. There can be no assurance that we will be able to detect and fix any defects. If our electrolyte or cell design fails to perform as expected, we could lose licensing contracts and customers of our electrolyte.

In addition, because we have a limited frame of reference from which to evaluate the long-term performance of our electrolyte and cell designs, it is possible that issues or problems will arise once our technology has been deployed for a longer period. If our customers determine our technology does not perform as expected, they may delay deliveries, terminate further orders, or initiate product recalls, each of which could adversely affect our business, prospects, and results of operations.

We have only conducted preliminary safety testing on our cells. Our cells 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, our cells will have to undergo extensive safety testing. We cannot assure you such tests will be successful. We have identified and may identify different or new safety issues during our cell development that have not been present previously. We may have to make cell design or manufacturing process changes to address any safety issues, which could lead to delays to or suspension of commercialization, which could materially damage our business, prospects, financial condition, operating results and brand.



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

We have entered into JDAs with three key partners, BMW, Ford and SK On. We are actively seeking additional partnerships with other OEMs or top tier battery manufacturers in an effort to diversify our development risk. If we are not successful in establishing partnerships with other OEMs or battery manufacturers, we will remain highly dependent upon our existing three partners. Because we generally cannot control the pace or extent of our partners' collaborative efforts with us, the pacing of our efforts generally must align with that of each partner. As a result, a failure to diversify may have the impact of preventing us from controlling the timing at which our cell technology and electrolyte mature to commercialization.

We may not succeed in developing solid-state battery cells for commercialization under our JDAs within the time parameters specified therein. If we do not meet the milestones in certain JDAs, our partners may terminate them without liability to us. Termination of a JDA by a partner, particularly a key partner like BMW, Ford or SK On, could impair our reputation and prospects materially.

We have entered into non-exclusive JDAs, including with BMW, Ford and SK On, to collaborate on the research and development of our cells. The terms of some of these JDAs 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. There is no assurance that we will be able to complete research and development in the time frame required by the JDAs and if we are unable to, our partners may terminate their participation in the JDAs. Given the importance to us of these relationships, the termination of a JDA by a partner could impair our reputation and prospects materially.

The non-exclusive nature of our JDAs exposes us to the risk that our partners may elect to pursue other battery cell technologies, which likely would impair our revenue generating ability.

Our OEM 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 JDAs with our current and future competitors. If other technology is developed more rapidly than our cells, or if such competing technologies are determined to be more efficient or effective than our cells, our partners may elect to adopt and install a competitor’s battery cell technology or products over ours, which could materially impact our business, financial results, and prospects.

Our business depends on our ability to manage our relationships with existing and future partners, customers, and suppliers. We may not succeed in managing these business relationships, which could slow our development progress and impair our business prospects.

Our OEM partners, other customers, and suppliers 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 JDAs, and in particular as any issue might impact development work underway under the JDAs. Any significant disagreements with them, and especially if we become dependent on that OEM partner for our research and development efforts, may impede our ability to maximize the benefits of our partnerships and slow the commercial roll-out of our cell designs. In addition, if our partners are unable or unwilling to meet their economic or other obligations under the JDAs, we may be required to fulfill those obligations alone, which could delay research and development progress and otherwise negatively impact our business and financial results. We expect that the particular interests of our partners may dictate future research and development efforts in regard to cell design. As a result, we may need to expand our technical staffing team in the future, and particularly if we succeed in adding new development partners. Furthermore, the relationships we have with our existing partners and the rights our partners’ rights have under their respective JDAs, may deter other OEMs and cell manufacturers from working with us. If we are not able to expand our other customer relationships, our business and prospects could be materially harmed.

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

Our JDAs provide a framework for our cooperation, and certain of the JDAs contemplate that we will enter into additional arrangements with our partners for the purchase and pricing of electrolyte materials for integration into our cell design, as well as licensing our cell technology to cell producers. We have not reached agreement on key commercial terms with any of these partners



and the structure for realizing the monetary value of our products is unknown. There can be no assurance that we will be able to agree with our partners on these key elements or that any terms will be financially beneficial for us.

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

Certain of our JDAs 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 JDA for use in the partner’s products. Furthermore, to the extent 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 JDA with such partner in performance of our other partners’ JDAs, which could prevent us from scaling the development or deploying it in work with all of our partners. There are no assurances we will maintain the access we need to any intellectual property of our partners or that any jointly developed intellectual property will be adequately protected, or that our partners will not seek to capitalize on jointly developed intellectual property for their sole benefit, such as through licensing agreements or other contractual arrangements they may enter with third parties that do not benefit us. In certain of our JDAs to date, 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 affect our revenue.

## We are subject to risks relating to production scale manufacturing of our cells through partners in the longer term.

Our business plan contemplates top tier battery cell suppliers and OEMs will manufacture our cell designs pursuant to licensing agreements with us. A component of our plan is to develop our products in such a way as to enable our manufacturing partners to utilize existing lithium-ion battery cell manufacturing processes and equipment. While we believe our development of a manufacturing process compatible with existing lithium-ion battery cell manufacturing lines provides 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 likely would 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. All of the foregoing could hinder our ability to successfully launch and 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 process. We could experience delays if our partners do not meet agreed upon timelines or experience capacity constraints. There is risk of potential disputes with partners, which could stop or slow battery cell production, and we could be affected by adverse publicity related to our partners, whether or not such publicity is related to such third parties' 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.

We may be unable to enter into agreements with cell manufacturers on terms and conditions acceptable to us and therefore 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. The expense and time required to adequately complete any transition may be greater than anticipated. Any of the foregoing could adversely affect our business, results of operations, financial condition and prospects.



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

Our business model contemplates that we will construct additional facilities for research and development and eventually commercial electrolyte manufacturing. In the near-term, we are nearing completion of a facility for advanced research and development and scaling of our electrolyte material production. In the longer-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 or permits 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 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 consents, permits, licenses, 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 battery cells and our business will be harmed.

We rely on complex equipment for our operations, and production 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 battery cells and electrolyte. The work required to integrate this equipment into the production of our cells and electrolyte manufacturing 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 result in additional cost to our cell technology.

Our current manufacturing facilities require, and we expect 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. We do not expect to maintain any redundancies in our research and development facilities, so unexpected malfunctions of our production equipment may significantly affect our operational efficiency. In addition, because this equipment has historically not been used to build solid-state battery cells or sulfide-based electrolyte, 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, but not limited to, 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, fires, seismic activity and other natural disasters.

Problems with our manufacturing equipment could result in the personal injury to or death of workers, the loss of production equipment, damage to manufacturing facilities, monetary losses, delays and unanticipated fluctuations in production. In addition, in some cases operational problems may result in environmental damage, administrative fines, increased insurance costs and potential legal liabilities. Any of these operational problems, or a combination of them could have a material adverse effect on our business, results of operations, cash flows, financial condition or prospects.

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 components and equipment necessary to develop our battery cells and produce our electrolyte, including key supplies, such as Li2S, NMC, silicon, lithium metal foil and manufacturing tools. We face risks relating to the availability 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 components, including Li2S, are not currently produced at a scale we believe necessary to support our proposed commercial operations. To the extent that 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 battery cells, electrolyte, and related technologies 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 components, equipment or materials could temporarily disrupt research and development activities or production of our battery cells or electrolyte until an alternative supplier is able to supply the required material. For example, in 2022 we suffered supply chain issues while constructing our electrolyte facility, which led to delays in bringing the facility online. Changes in business conditions, unforeseen circumstances, governmental changes, transportation disruptions, and other factors beyond our control or which we do not presently anticipate, could also affect our suppliers' ability to deliver components or equipment to us on a timely basis. Any of the foregoing could materially and adversely affect our results of operations, financial condition and prospects. Currency fluctuations, trade barriers, tariffs or shortages and other general economic or political conditions may limit our ability to obtain key components or equipment for our cells or electrolyte or significantly increase freight charges, raw material costs and other expenses associated with our business, which could further materially and adversely affect our results of operations, financial condition and prospects.

We may be unable to adequately control the costs associated with our operations and the components necessary to build our battery cells and electrolyte material, and, if we are unable to control these costs and achieve cost advantages in our production of cells or electrolyte at scale, our business will be adversely affected.

We require significant capital to develop our solid-state battery cell technologies and expect to incur significant expenses, including those relating to research and development, raw material procurement, leases, sales and distribution as we build our brand and market our technologies, and general and administrative costs as we scale our operations. Our ability to become profitable in the future will not only depend on our ability to successfully develop and market our electrolyte and cells, but also to control our costs. If we are unable to efficiently design, appropriately price, sell and distribute our electrolyte and cell technologies, our anticipated margins, profitability and prospects would be materially and adversely affected.

## 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 may be severely disrupted if we lost their services. Departures of key executives, as experienced in late 2022 upon the retirement of our former CEO, Douglas Campbell, may result in stockholder uncertainty and cause the market prices for our securities to decline. We continue to be highly dependent on the services of Derek Johnson, our Chief Operating Officer, our other executive officers, and other senior technical and management personnel, who would be difficult to replace. If Dr. Johnson or other key personnel were to depart, we may not be able to successfully attract and retain the personnel necessary to grow our business. As we build our brand and become more well known, there is increased risk that competitors or other companies will seek to hire our personnel. Many of our technical personnel have been long-time employees and hold stock options which are currently exercisable and significantly “in-the-money” at current market prices. Despite our efforts to retain them, these employees could decide to exercise such options and pursue other opportunities. Our success also depends on our continuing ability to identify, hire, attract, train and develop other highly qualified personnel. Competition for these employees can be intense, and our ability to hire, attract and retain them depends on our ability to provide competitive compensation. We may not be able to attract, assimilate, develop or retain qualified personnel in the future, and our failure to do so could seriously harm our business and prospects.

## Our insurance coverage may not be adequate to protect us from all business risks.

We may be subject, in the ordinary course of business, to losses resulting from products liability, accidents, acts of God, and other claims against us, for which we may have no insurance coverage. As a general matter, the policies that we do have may include significant deductibles, and we cannot be certain that our insurance coverage will be sufficient to cover all future losses or claims against us. A loss that is uninsured or which exceeds policy limits may require us to pay substantial amounts, which could adversely affect our financial condition and operating results. Furthermore, although we plan to obtain and maintain insurance for damage to our property and the disruption of our business, this insurance may be challenging to obtain and maintain on terms acceptable to us and may not be sufficient to cover all of our potential losses.



Our facilities or operations could be damaged or adversely affected as a result of natural disasters and other catastrophic events, including fire and explosions.

Our current and future development and manufacturing facilities or operations could be adversely affected by events outside of our control, such as natural disasters, wars, health pandemics and epidemics such as the ongoing COVID-19 pandemic, and other calamities. As an example, in December 2021, the Louisville, Colorado area was significantly affected by the Marshall fire, which destroyed a significant number of buildings and disrupted a number of businesses. We cannot provide assurance that any backup systems will be adequate to protect us from the effects of fire, explosions, floods, cyber-attacks (including ransomware attacks), typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks or similar events. Any of the foregoing events may give rise to interruptions, breakdowns, system failures, technology platform failures or internet failures, which could cause the loss or corruption of data or malfunctions of software or hardware as well as adversely affect our ability to conduct our research and development activities as and on the timeline currently contemplated.

We have been, and may in the future be, adversely affected by epidemics, pandemics or other outbreaks.

We face various risks related to epidemics, pandemics, and other outbreaks, including the COVID-19 pandemic and/or any other pandemic. 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.

Various aspects of our business cannot be conducted remotely, including many aspects of the research and development and manufacturing of our electrolyte and cells. The extent to which a future pandemic, impacts our business, prospects and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the pandemic, its severity, the actions to contain the virus or treat its impact, mutations in the virus, vaccine distribution and uptake, the impact on our customers, employees, and vendors, and how quickly and to what extent normal economic and operating activities can resume.

## Risks Related to Industry and Market Trends

If solid-state battery cell technology does not become widely accepted, we may not be successful in generating revenues from the manufacture and sale of our electrolyte.

Our business plan contemplates that we will develop the necessary production capabilities to manufacture our electrolyte for sale to top tier battery suppliers and OEMs that have determined to manufacture solid-state battery cells. If a market for sulfide-based solid-state battery cells does not develop in the time or to the level we anticipate, we might not be able to generate revenues from this product line. This may prevent us from achieving our financial projections or recouping the costs we expect to incur in scaling our production of our electrolyte.

The battery cell 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 business prospects among current and future partners and customers.

The battery cell market in which we compete continues to evolve and is highly competitive. To date, we have focused our efforts on our sulfide-based solid-state battery cell technology, a promising alternative to conventional lithium-ion battery cell technology. However, lithium-ion battery cell technology has been widely adopted and our current competitors have, and future competitors may have, greater resources than we do and may also be able to devote greater resources to the development of their current and future technologies. These competitors also may 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 cell manufacturers may continue to reduce cost and expand supply of conventional batteries and, therefore, reduce the prospects for our business or negatively impact the ability for us to sell our products at a market-competitive price and yet at sufficient margins.



Many OEMs are researching and investing in solid-state battery cell efforts and, in some cases, in battery cell development and production. We do not have exclusive relationships with any OEM to provide their future battery cell technologies, and it is possible that the investments made by these OEMs might result in technological advances earlier than, or superior in certain respect to, the battery cells we are developing. There are a number of companies seeking to develop alternative approaches to solid-state battery cell technology. We expect competition in battery cell technology and EVs to intensify due to increased demand for these vehicles and a regulatory push for EVs, continuing globalization, and consolidation in the worldwide automotive industry. As new companies and larger, existing vehicle and battery cell 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 position in the market.

Furthermore, the battery cell 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 batteries technology made by competitors may materially adversely affect 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 such technologies achieve lower prices or enjoy greater policy support than the lithium-ion battery cell industry, our competitive position and growth prospects may be harmed. Similarly, if we fail to accurately predict and ensure that our solid-state battery cell technology can address customers' changing needs or emerging technological trends, or if our customers fail to achieve the benefits expected from our battery cells, our business will be harmed.

We must continue to commit significant resources to develop our cell technology in order to establish a competitive position, and these commitments must be made without knowing whether our investments will result in products potential customers will accept. There is no assurance we will successfully identify new customer requirements, develop and bring our cell technology or electrolyte to market on a timely basis, or that products and technologies developed by others will not render our cells or electrolyte obsolete or noncompetitive, any of which would adversely affect our business and operating results.

We expect that OEMs and top tier battery cell suppliers will be less likely to license our cell designs and/or incorporate our electrolyte if they are not convinced that our business will succeed in the long term. Similarly, suppliers and other third parties will 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 business prospects. Maintaining such confidence may be particularly complicated by certain factors including those that are largely outside of our control, such as:

• our limited operating history;

• market unfamiliarity with our products;

• delays in or impediments to completing or achieving our research and development goals;

- unexpected costs that OEM and top tier cell partners may be required to incur to scale manufacturing, delivery and service operations to meet demand for EVs containing our technologies or products;

• competition and uncertainty regarding the future of EVs;

- the development and adoption of competing technologies that are less expensive and/or more effective than our products; and

• our eventual production and sales performance compared with market expectations.



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

Our growth and future demand for our products is 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 rapidly changing technologies, competitive pricing and factors, evolving government regulation and industry standards, and changing consumer demands and behaviors. If the market for EVs in general does not develop as expected, or develops more slowly than expected, our business, prospects, financial condition and operating results could be harmed.

We may not succeed in attracting customers during the development stage or for high volume commercial production, and our future growth and success depend on our ability to attract customers.

We may not succeed in attracting customers during our development stage or for high volume commercial production. Customers may be wary of unproven products or not be inclined to work with less established businesses. In addition, if we are unable to attract new customers in need of high-volume commercial production of our products, our business will be harmed.

OEMs are often large enterprises. Therefore, our future success will depend on our or our partners' ability to effectively sell our products to such large customers. Sales to these end-customers involve risks that may not be present (or that are present to a lesser extent) with sales to smaller customers. These risks include, but are not limited to, (i) increased purchasing power and leverage held by large customers in negotiating contractual arrangements with us and (ii) longer sales cycles and the associated risk that substantial time and resources may be spent on a potential end-customer that elects not to purchase our products.

OEMs that are large organizations often undertake a significant evaluation process that results in a lengthy sales cycle. Large organizations typically have longer implementation cycles, require greater product functionality and scalability, require a broader range of services, and demand that vendors take on a larger share of risks. All of these factors can add further risk to business conducted with these potential customers.

We may not be able to accurately estimate the future supply and demand for our cells and/or our electrolyte, which could result in a variety of inefficiencies in our business and hinder our ability to generate revenue. If we fail to accurately predict our manufacturing requirements, we could incur additional costs or experience delays.

It is difficult to predict our future revenues 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 current and future suppliers prior to the scheduled delivery of products to potential customers. Currently, there is no historical basis for making judgments on the demand for our cells and/or our electrolyte or our ability to develop, manufacture, and deliver such products, or our profitability in the future. If we overestimate our requirements, our suppliers may have excessive inventory, which indirectly would 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 cells and/or our electrolyte to our potential customers could be delayed, which would harm our business, financial condition and operating results.



## Risks Related to Intellectual Property

We rely heavily on owned and exclusively-licensed intellectual property, which includes patent rights, trade secrets, copyright, trademarks, and know-how. If we are unable to protect and maintain access to these intellectual property rights, our business and competitive position would be harmed.

We may not be able to prevent unauthorized use of our owned and exclusively-licensed intellectual property, which could harm our business and competitive position. 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 proprietary technologies. In addition, we seek to protect our intellectual property rights through nondisclosure 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 proprietary rights, third parties, including our vendors, customers, partners, 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. In addition, 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 our patents being infringed or our know-how or trade secrets stolen.

Monitoring 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 could divert management’s attention, all of which could harm our business, results of operations and financial condition. In addition, existing intellectual property laws and contractual remedies may afford less protection than needed to safeguard our proprietary technologies. 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 could harm our ability to maintain any competitive advantage those patent rights provide.

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. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of the United States and efforts to protect against the unauthorized use of our intellectual property rights, technology and other proprietary rights may be impossible outside of the United States. Failure to adequately protect our owned and exclusively-licensed intellectual property rights could result in our competitors using our intellectual property to offer products, potentially resulting in the loss of some of our competitive advantage, a decrease in our revenue and reputational harm caused by inferior products offered by third parties, which would adversely affect our business, prospects, financial condition and operating results.

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

There are risks to technology and intellectual property that may result from us conducting business outside the United States, particularly in jurisdictions that do not have comparable levels of protection of corporate proprietary information and assets such as intellectual property, trademarks, and trade secrets. For instance, we may be exposed to material risks of theft of proprietary technology and other intellectual property, including technical data, business processes, production processes, formulas, data sets or other sensitive information. While these risks are common to many companies, conducting business in certain foreign jurisdictions, housing technology, data and intellectual property abroad, or licensing technology to foreign partners may present more significant exposure.



Our patent applications may not result in issued patents, which would result in the disclosures in those applications being available to the public. Also, our patent rights may be contested, circumvented, invalidated or limited in scope, any of which could have a material adverse effect on our ability to prevent others from interfering with commercialization of our products.

Our patent portfolio includes some patent applications. Our patent applications may not result in issued patents, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to our products to our disadvantage. 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 the patent applications that we file will result in patents being issued, or that our patents and any patents that may be issued to us will afford protection against competitors with similar technology. Numerous patents and pending patent applications owned by others exist in the fields in which we have developed and are developing our technology, which could prevent us from obtaining a patent. In addition to those who may claim priority, any of our future or existing patents or pending patent applications (including those we have rights to under exclusive license) may also be challenged by others on the basis that they are otherwise invalid or unenforceable. Furthermore, patent applications filed in foreign countries may be subject to laws, rules and procedures that differ from those of the United States, and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued.

We have not performed exhaustive searches or analyses of the intellectual property landscape of the battery industry; therefore, we are unable to guarantee that our technology, or its ultimate integration into EV battery packs, 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 could cause us to incur substantial costs.

Companies, organizations or individuals, including our current and future competitors, may hold or obtain patents, trademarks or other proprietary rights that would prevent, limit or interfere with our ability to make, use, develop, sell, license, lease or market our products or technologies, which could make it more difficult for us to operate our business. From time to time, we may receive inquiries from third parties relating to whether we are infringing their intellectual property rights and/or seek court declarations that they do not infringe upon our intellectual property rights. Companies holding patents or other intellectual property rights relating to batteries may bring suits alleging infringement of such rights or otherwise asserting their rights and seeking licenses. In addition, if we are determined to have infringed upon a third party’s intellectual property rights, we may be required to do one or more of the following:

• cease selling, leasing, incorporating or using products that incorporate the challenged intellectual property;

• pay substantial damages;

• materially alter our research and development activities and proposed production processes;

• obtain a license from the holder of the infringed intellectual property right, which may not be available on reasonable terms or at all; or

• redesign our battery cells at significant expense.

In the event of a successful claim of infringement against us and our failure or inability to obtain a license to continue to use the technology on reasonable terms, our business, prospects, operating results and financial condition could be materially adversely affected. In addition, any litigation or claims, whether or not well-founded, could result in substantial costs, negative publicity, reputational harm and diversion of resources and management’s attention.

We also license patents and other intellectual property from third parties, and we 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 under our license contracts with them as permitted by our license agreements. However, our rights to indemnification may be unavailable or insufficient to cover our costs and losses, depending on our use of the technology, whether we choose to retain control over conduct of the litigation, and other factors.



## Risks Related to Our Limited Operating History

Our business model has yet to be tested and any failure to execute on our strategic plans, including commercialization, would have a material adverse effect on our operating results and business, harm our reputation and could result in substantial liabilities that exceed our resources.

Investors should be aware of the difficulties normally encountered by a new enterprise, many of which are beyond our control, 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 risks, expenses, complications, delays and the competitive environment in which we operate. There is, therefore, 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 risks and difficulties frequently experienced by early commercial stage companies, including scaling up our infrastructure and 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. In the event that actual results differ from our estimates or we adjust our estimates in future periods, our operating results, prospects and financial position could be materially 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 $59.1 million for the year ended December 31, 2022 and an accumulated deficit of approximately $19.0 million from our inception in 2012 through December 31, 2022. We believe that we will continue to incur operating losses each quarter until the time significant production of our cell designs or sales of our electrolyte begins. As disclosed above, 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 development partners, making it difficult to predict when we will begin to recognize material revenues from our cell technology or electrolyte.

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 materials and cells; 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.

We may need additional capital before we commence generating material revenues, and it may not be available on acceptable terms, if at all. For example, our budgets assume, among other things, that our development timeline progresses as planned and our corresponding expenditures are consistent with current expectations, both of which have been derived based on discussions with our key partners only and do not factor in the possibility of additional partnerships. Accordingly, our expectations regarding our capital needs are dynamic and changing, and are subject to various risks and uncertainties, including those described herein.

More specifically, our capital expenditures and operating and development requirements have increased materially as we accelerate our research and development efforts and 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 our operating expenses will increase substantially due to increased headcount and other general and administrative expenses necessary to support a rapidly growing public company.



As a result, we may need to access the debt and equity capital markets to obtain additional financing in the future. However, these sources of financing may not be available on acceptable terms, or at all. Our ability to obtain additional financing will be subject to a number of factors, including:

• market conditions;

- the level of success we have experienced with our research and development programs;

• our operating performance;

• investor sentiment; and

• our ability to incur additional debt in compliance with any agreements governing our then-outstanding debt.

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 currently 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, which may adversely affect our business, operating results, financial condition and prospects.

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

We intend to use our cash on hand to expand our operations significantly, with a view toward accelerating our research and development activities and positioning our company for potential commercialization of our technologies. In connection with these efforts, we anticipate hiring, retaining and training personnel, establishing manufacturing plants and other facilities, and implementing administrative infrastructure, systems and processes. 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 result in a significant return or any return at all for our stockholders. In addition, pending their use, we may invest the cash we hold in a manner that does not produce income or that loses value. If we cannot manage our growth effectively, including by controlling our expenditures for these initiatives to the greatest extent possible, our business could be harmed.

Our interim CEO and several of our other executive officers have only limited experience in operating a public company.

We are evaluating candidates for our chief executive officer position. We cannot assure you of the timing for completion of our recruitment efforts for this key position. Our interim CEO and several of our executive officers have only limited experience in the management of a publicly traded company. Our management team may not successfully or effectively manage being a public company subject to significant regulatory oversight and reporting obligations under federal securities laws. We may not have adequate personnel with the appropriate level of knowledge, experience, and training in the policies, practices or internal controls over financial reporting required of public companies in the United States. As a result, we may be required to pay higher outside legal, accounting or consulting costs than our competitors, and our management team members may have to devote a higher proportion of their time to issues relating to compliance with the laws applicable to public companies, both of which might put us at a disadvantage relative to competitors.

We may not succeed in establishing, maintaining and strengthening our brand, which would materially and adversely affect customer acceptance of our technologies and our business, revenues and prospects.

Our business and prospects depend on our ability to develop, maintain and strengthen our brand. If we are not able to establish, maintain and strengthen our brand, we may lose the opportunity to build a critical mass of customers. The automobile industry is intensely competitive, and we may not be successful in building, maintaining and strengthening our brand. Our current and potential competitors, including many battery 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, our business, prospects, financial condition and operating results will be materially and adversely impacted.



## Risks Related to Finance and Accounting

Our expectations and targets regarding the times when we will achieve various technical, pre-production and production-level performance objectives depend in large part upon assumptions, estimates, measurements, testing, analyses and data developed and performed by us, which if incorrect or flawed, could have a material adverse effect on our actual operating results and performance.

Our expectations and targets regarding the times when we will achieve various technical, pre-production and production objectives reflect our current expectations and estimates. Whether we will achieve these objectives when we expect depends on a number of factors, many of which are outside our control, including, but not limited to:

- success and timing of our development activity and ability to develop cells that achieve our desired performance metrics and achieve the requisite automotive industry validations before our competitors;

- our success in securing additional development partnerships and the pace of our efforts with each of them;

• unanticipated technical or manufacturing challenges or delays;

• difficulties identifying or constructing the necessary research and development and manufacturing facilities;

- technological developments relating to lithium-ion, lithium-metal solid-state or other batteries that could adversely affect the commercial potential of our technologies;

- the extent of consumer acceptance of EVs generally, and those deploying our products, in particular;

- competition, including from established and future competitors in the battery cell industry or from competing technologies such as hydrogen fuel cells that may be used to power EVs;

- whether we can obtain sufficient capital when required to build our manufacturing facilities and sustain and grow our business;

- adverse developments in our partnership relationships, including termination of our partnerships or changes in our partners' timetables and business plans, which could hinder our development efforts;

• our ability to manage our growth;

• whether we can manage relationships with key suppliers and the availability of the raw materials we need to procure from them;

• our ability to retain existing key management, integrate recent hires and attract, retain and motivate qualified personnel; and

• the overall strength and stability of domestic and international economies.

Unfavorable changes in any of these or other factors, most of which are beyond our control, could materially and adversely affect our ability to achieve our objectives when planned and our business, results of operations and financial results.

Additionally, we cannot predict market reaction or the impact on the market price of our common stock as we make announcements regarding our achievement or failure to achieve our objectives and/or milestones we have publicly disclosed. Any negative market reactions as we make such announcements could result in the volatility of the price of our common stock.



Incorrect estimates or assumptions by management in connection with the preparation of our financial statements could adversely affect 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, income, revenue or expenses during the reporting periods. Incorrect estimates and assumptions by management could adversely affect our reported amounts of assets, liabilities, income, revenue and expenses during the reporting periods. If we make incorrect assumptions or estimates, our reported financial results may be over or understated, which could materially and adversely affect our business, financial condition and results of operations.

If we are unable to maintain an effective system of internal controls and procedures required by the Sarbanes-Oxley Act, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our stock price, business and operating results.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. A material weakness is a deficiency, or a combination of deficiencies, in internal controls over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Any newly-identified material weaknesses could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. Efforts to remediate a material weakness, as we experienced in 2021 and 2022, may be time consuming and costly and there is no assurance that these initiatives will ultimately have the intended effects and permit us to timely file our periodic financial reports. If we are unable to maintain compliance with securities law requirements regarding timely filing of periodic reports or applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result and we could become subject to litigation or investigations by the SEC or other regulatory authorities, which could require additional financial and management resources. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.

We incur significant expenses and administrative burdens as a public company, which could have an adverse effect on our business, financial condition and results of operations.

As a public company, we face increased legal, accounting, administrative and other costs and expenses that we did not face as a private company. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, the PCAOB, and the securities exchanges impose additional reporting and other obligations on public companies. The development and implementation of the standards and controls necessary for us to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. We will be required to expand our employee base and hire additional employees to support our operations as a public company, which will increase our operating costs in future periods.

Compliance with public company requirements increases costs and makes certain activities more time-consuming. A number of those requirements require us to carry out activities we have not done previously. For example, our Board has committees that did not exist when we were a private company and we have adopted new internal controls and disclosure controls and procedures. In addition, we incur significant expenses associated with SEC reporting requirements. Furthermore, if any issues in complying with those requirements are identified (for example, if the auditors identify a material weakness or significant deficiency in the internal control over financial reporting), we could incur additional costs rectifying those issues, and the existence of those issues could adversely affect our reputation or investor perceptions of it. As a public company, it is also more expensive to obtain director and officer liability insurance. The additional reporting and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related legal, accounting and administrative activities. These increased costs will require us to spend money that could otherwise be used on our research and development programs and to achieve strategic objectives. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.



Our ability to utilize our net operating loss and tax credit carryforwards to offset future taxable income may be subject to certain limitations.

In general, under Section 382 of the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to use its pre-change NOLs to offset future taxable income. The limitations apply if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50 percentage point change (by value) in its 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 limitations on our ability to utilize our existing NOLs and other tax attributes to offset taxable income or tax liability. In addition, the business combination and future changes in our stock ownership, which may be outside of our control, may trigger an ownership change. Similar provisions of state tax law may also apply to limit our use of accumulated state tax attributes. As a result, even if we earn net taxable income in the future, our ability to use our pre-change NOLs and other tax attributes to offset such taxable income or tax liability may be subject to limitations, which could potentially result in increased future income tax liability to us.

There is also a risk that changes in law or regulatory changes may result in suspensions on the use of NOLs or tax credits, possibly with retroactive effect, and our existing NOLs or tax credits expiring or otherwise being unavailable to offset future income tax liabilities.

The unavailability, reduction or elimination of government and economic incentives could have a material adverse effect on our business, prospects, financial condition and operating results.

We currently, and expect to continue to, benefit directly and indirectly from certain government grants, subsidies and economic incentives including tax credits, rebates and other incentives that support the development and adoption of clean energy technology. We cannot assure you that these grants, subsidies and incentive programs will be available to us at the same or comparable levels in the future. Any reduction, elimination or discriminatory application of government grants, subsidies and economic incentives because of policy changes, or the reduced need for such grants, subsidies and incentives due to the perceived success of clean and renewable energy products or other reasons, may require us to seek additional financing, which may not be obtainable on commercially attractive terms or at all, and may result in the diminished competitiveness of the battery cell industry generally or our solid-state battery cells in particular. Any change in the level of grants, subsidies and incentives from which we benefit could materially and adversely affect our business, prospects, financial condition and operating results.

## Risks Related to Legal and Regulatory Compliance

We may become subject to product liability claims, which could harm our financial condition and liquidity if we are not able to successfully defend or insure against such claims.

If we are successful in our commercialization efforts, we may become subject to product liability claims which could harm our business, prospects, operating results, and financial condition. We face inherent risk of exposure to claims in the event our battery cells do not perform as expected or malfunction resulting in personal injury or death. Our risks in this area are particularly pronounced given our cells and electrolyte are still in the development stage and have not yet been commercially tested or mass produced. A successful product liability claim against us could require us to pay a substantial monetary award. Moreover, a product liability claim could generate substantial negative publicity about our technology and business and inhibit or prevent commercialization of our cells and electrolyte and future product candidates, which would have a material adverse effect on our brand, business, prospects and operating results. Any insurance coverage might not be sufficient to cover all potential product liability claims. Any lawsuit seeking monetary damages either in excess of our coverage, or outside of our coverage, may have a material adverse effect on our reputation, business and financial condition. We may not be able to secure additional product liability insurance coverage on commercially acceptable terms or at reasonable costs when needed, particularly if we do face liability for our products and are forced to make a claim under then-existing policies.



From time to time, we may be involved in litigation, regulatory actions or government investigations and inquiries, which could have an adverse impact on our profitability and consolidated financial position.

We may be involved in a variety of litigation, other claims, suits, regulatory actions or government investigations and inquiries and commercial or contractual disputes that, from time to time, are significant. In addition, from time to time, we may also be involved in legal proceedings and investigations arising in the normal course of business including, without limitation, commercial or contractual disputes, including warranty claims and other disputes with potential customers, former employees and suppliers, intellectual property matters, personal injury claims, environmental issues, tax matters, and employment matters. For example, in connection with the business combination, we received a demand letter from an alleged stockholder of DCRC relating to the proposals for which we sought stockholder approval at the special meeting of stockholders on December 7, 2021. We incurred costs in responding to, and ultimately settling with, such alleged stockholder.

We are subject to substantial regulation, and unfavorable changes to, or failure by us to comply with, these regulations could substantially harm our business and operating results.

The sale of EVs, and motor vehicles in general, is subject to substantial regulation under international, federal, state and local laws, including export control laws and other international trade regulations, which are continuously evolving as technology develops and becomes more widely adopted. We anticipate that our battery cells and electrolyte also would be subject to these regulations, and we expect to incur significant costs in complying with these regulations.

The U.S. government has made and continues to make significant changes in U.S. trade policy and has taken certain actions that could negatively 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, imposing additional trade controls on a wide range of American products and companies. The U.S. or foreign governments may take additional administrative, legislative, or regulatory action that could materially interfere with our ability to source and procure the raw materials we need for our research and development activities and, in the future, to sell products in certain countries. 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 long-term changes to global trade. Any alterations to our business strategy or operations made in order to adapt to or comply with any such changes could be time-consuming and expensive, and certain of our competitors may be better suited to withstand or react to these changes.

To the extent the laws change, our products may not comply with applicable international, federal, state or local laws, which would have an adverse effect on our business. Compliance with changing regulations could be burdensome, time consuming, and expensive. To the extent compliance with new regulations is cost prohibitive, our business, prospects, financial condition and operating results would be adversely affected.

Internationally, there may be laws in jurisdictions we have not yet entered or laws we are unaware of in jurisdictions we have entered that may restrict our sales or other business practices. The laws in this area can be complex, difficult to interpret and may change over time. Continued regulatory limitations and other obstacles that may interfere with our ability to commercialize our products could have a negative and material impact on our business, prospects, financial condition and results of operations.



Our technology and our website, systems, and data we maintain may be subject to intentional disruption, other security incidents, or alleged violations of laws, regulations, or other obligations relating to data handling that could result in liability and adversely impact our reputation and future sales. We may be required to expend significant resources to continue to modify or enhance our protective measures to detect, investigate and remediate vulnerabilities to security incidents, including measures impacting our ability to develop and maintain a supply chain. In addition, we will be required to comply with rapidly evolving laws and regulations legislation in this area. Any future failure by us to comply with applicable cybersecurity or data privacy legislation or regulation could have a material adverse effect on our business, reputation, results of operations or financial condition.

We expect to face significant challenges with respect to information security and maintaining the security and integrity of our systems and other systems used in our business, as well as with respect to the data stored on or processed by these systems. We also anticipate receiving and storing confidential business information of our partners and customers. Advances in technology, an increased level of sophistication and expertise of hackers, and new discoveries in the field of cryptography can result in a compromise or breach of the systems used in our business or of security measures used in our business to protect confidential information, personal information, and other data. We may be a target for attacks designed to disrupt our operations or to attempt to gain access to our systems or to data that we possess, including proprietary information that we obtain from our partners pursuant to our JDAs with them. We also are at risk for interruptions, outages and breaches of our and our outsourced service providers' operational systems and security systems, our integrated software and technology, and data that we or our third-party service providers process or possess. These may be caused by, among other causes, physical theft, viruses or other malicious code, denial or degradation of service attacks, ransomware, social engineering schemes, and insider theft or misuse.

The availability and effectiveness of our cell technology and our ability to conduct our business and operations depend on the continued operation of information technology and communications systems, some of which we have yet to develop or otherwise obtain the ability to use. Systems we currently use or may use in the future in conducting our business, including data centers and other information technology systems, will be vulnerable to damage or interruption. Such systems could also be subject to break-ins, sabotage and intentional acts of vandalism, as well as disruptions and security incidents as a result of non-technical issues, including intentional or inadvertent acts or omissions by employees, service providers, or others. We currently use, and may use in the future, outsourced service providers to help provide certain services, and any such outsourced service providers face similar security and system disruption risks as us. Our ability to monitor our outsourced service providers' security measures is limited, and, in any event, third parties may be able to circumvent those security measures, resulting in the unauthorized access to, misuse, acquisition, disclosure, loss, alteration, or destruction of personal, confidential, or other data, including data relating to individuals. Some of the systems used in our business will not be fully redundant, and our disaster recovery planning cannot account for all eventualities. Any data security incidents or other disruptions to any data centers or other systems used in our business could result in lengthy interruptions in our service and may adversely affect our business, prospects, financial condition, reputation and operating results.

Significant capital and other resources may be required in efforts to protect against information security breaches, security incidents, and system disruptions, or to alleviate problems caused by actual or suspected information security breaches and other data security incidents and system disruptions. The resources required may increase over time as the methods used by hackers and others engaged in online criminal activities and otherwise seeking to obtain unauthorized access to systems or data, and to disrupt systems, are increasingly sophisticated and constantly evolving. In particular, ransomware attacks have become more prevalent in the industrial sector, which could materially and adversely affect our ability to operate and may result in significant expense.

In addition, we may face increased compliance burdens regarding such requirements with regulators and customers regarding our products and services and also incur additional costs for oversight and monitoring of our supply chain. These additional compliance and logistical burdens are attenuated through our international partnerships. We also cannot be certain that these systems, networks, and other infrastructure or technology upon which we rely, including those of our third-party suppliers or service providers, will be effectively implemented, maintained or expanded as planned, or will be free from bugs, defects, errors, vulnerabilities, viruses, or malicious code. We may be required to expend significant resources to make corrections or to remediate issues that are identified or to find alternative sources.



Any failure or perceived failure by us or our service providers to prevent information security breaches or other security incidents or system disruptions, or any compromise of security that results in or is perceived or reported to result in unauthorized access to, or loss, theft, alteration, release or transfer of, our information, or any personal information, confidential information, or other data could result in loss or theft of proprietary or sensitive data and intellectual property, could harm our reputation and competitive position and could expose us to legal claims, regulatory investigations and proceedings, and fines, penalties, and other liability. Any such actual or perceived security breach, security incident or disruption could also divert the efforts of our technical and management personnel and could require us to incur significant costs and operational consequences in connection with investigating, remediating, eliminating and putting in place additional tools, devices, policies, and other measures designed to prevent actual or perceived security breaches and other incidents and system disruptions. Moreover, we could be required or otherwise find it appropriate to expend significant capital and other resources to respond to, notify third parties of, and otherwise address the incident or breach and its root cause, and most jurisdictions have enacted laws requiring companies to notify individuals, regulatory authorities and others of security breaches involving certain types of data.

Further, we cannot assure that any limitations of liability provisions in our current or future contracts that may be applicable would be enforceable or adequate or would otherwise protect us from any liabilities or damages with respect to any particular claim relating to a security breach or other security-related matter. We also cannot be sure that our existing insurance coverage will continue to be available on acceptable terms or will be available in sufficient amounts to cover claims related to a security breach or incident, or that the insurer will not deny coverage as to any future claim. The successful assertion of claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, including our financial condition, operating results, and reputation.

Additionally, laws, regulations, and other actual and potential obligations relating to privacy, data hosting and transparency of data, data protection, and data security are evolving rapidly, and we expect to potentially be subject to new laws and regulations, or new interpretations of laws and regulations, in the future in various jurisdictions. These laws, regulations, and other obligations, and changes in their interpretation, could require us to modify our operations and practices, restrict our activities, and increase our costs. Further, these laws, regulations, and other obligations are complex and evolving rapidly, and we cannot provide assurance that we will not claim, allegations, or other proceedings related to actual or alleged obligations relating to privacy, data protection, or data security. It is possible that these laws, regulations, and other obligations may be inconsistent with one another or be interpreted or asserted to be inconsistent with our business or practices. We anticipate needing to dedicate substantial resources to comply with laws, regulations, and other obligations relating to privacy and cybersecurity in order to comply. Any failure or alleged or perceived failure to comply with any applicable laws, regulations, or other obligations relating to privacy, data protection, or data security could also result in regulatory investigations and proceedings, and misuse of or failure to secure data relating to individuals could also result in claims and proceedings against us by governmental entities or others, penalties and other liability, and damage to our reputation and credibility, and could have a negative impact on our business, prospects, financial condition and operating results.

We are subject to various existing and future environmental health and safety laws, which may result in increased compliance costs or additional operating costs and restrictions. Failure to comply with such laws and regulations may result in substantial fines or other limitations that could adversely impact our financial results or operations.

Our company and our operations, as well as our contractors, suppliers, and customers, are subject to numerous federal, state, local and foreign environmental laws and regulations governing, among other things, the generation, storage, transportation, and disposal of hazardous substances and wastes. We are also subject to a variety of product stewardship and manufacturer responsibility laws and regulations, primarily relating to the collection, reuse and recycling of electronic waste, as well as regulations regarding the hazardous material contents of electronic product components and product packaging, and non-hazardous wastes. We or others in our supply chain may be required to obtain permits and comply with procedures that impose various restrictions and operations that could have adverse effects on our operations. If key permits and approvals cannot be obtained on acceptable terms, or if other operations requirements cannot be met in a manner satisfactory for our operations or on a timeline that meets our commercial obligations, it may adversely impact our business. There are also significant capital, operating and other costs associated with compliance with these environmental laws and regulations.



Environmental and health and safety laws and regulations are subject to change and may become more stringent in the future, such as through new regulations enacted at the supranational, national, sub-national, and/or local level or new or modified regulations that may be implemented under existing law. The nature and extent of any changes in these laws, rules, regulations, and permits may be unpredictable and may have material effects on our business. Future legislation and regulations or changes in existing legislation and regulations, or interpretations thereof, could cause additional expenditures, restrictions, and delays in connection with our operations as well as our other future projects, or may require us to manufacture with alternative technologies and materials.

Our manufacturing process creates regulated air emissions which are typically managed within established permit limits by available emissions control technology. Should permitted limits or other requirements change in the future, the company may be required to install additional, more costly control technology. If we were to violate any such permit or related permit conditions, we may incur significant fines and penalties.

We rely on third parties to ensure compliance with certain environmental laws, including those relating to the disposal of wastes. Any failure to properly handle or dispose of wastes, regardless of whether such failure is ours or our contractors, may result in liability under environmental laws, as well as liability for any impacts to human health or natural resources. The costs of liability with respect to contamination could have a material adverse effect on our business, financial condition, or results of operations. Additionally, we may not be able to secure contracts with third parties and contractors to continue their key supply chain and disposal services for our business, which may result in increased costs for compliance with environmental laws and regulations.

Our research and development activities expose our employees to potential occupational hazards such as, but not limited to, the presence of hazardous materials, machines with moving parts, and high voltage and/or high current electrical systems typical of large manufacturing equipment and related safety incidents. There may be safety incidents that damage machinery or product, slow or stop production, or harm employees. Employees may be exposed to toxic hydrogen sulfide as a result of the components we use being exposed to moisture. If released in an uncontrolled manner, this hydrogen sulfide can create hazardous working conditions. Consequences may include litigation, fines, increased insurance premiums, mandates to temporarily halt production, workers' compensation claims, or other actions that impact our brand, finances, or ability to operate.

Some of our operations involve the manufacture and/or handling of a variety of explosive and flammable materials. We might experience incidents such as leaks and ruptures, explosions, fires, transportation accidents involving our chemical products, chemical spills and other discharges or releases of toxic or hazardous substances or gases and environmental hazards in the future or that these incidents will not result in production delays or otherwise have a material adverse effect on our business, financial condition or results of operations, for which we may not be adequately insured.

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

We currently rely on government contracts and grants for a substantial portion of our revenue and to partially fund our research and development activities. Contracts and grants with government entities are subject to a number of risks. 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 that we will be successful. In the event that we are successful in being awarded a government contract or grant, such award may be subject to appeals, disputes, or litigation, including, but not limited to, bid protests by unsuccessful bidders. Availability of government funding for our solutions may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our solutions. Where government funds are used, the government may require all work to be performed in and/or certain products to be manufactured in the United States, and we may not manufacture all products in locations that meet government requirements, and as a result, our business and results of operations may suffer. Contracts with governmental entities may also include preferential pricing terms, including, but not limited to, “most favored customer” pricing and obligations to disclose aspects of how our pricing is developed. Additionally, we may be required to obtain special certifications to sell some or all of our solutions to government or quasi-government entities. Such certification requirements for our solutions may change, thereby restricting our ability to sell into the federal government sector until we have obtained such certification. If our products are late in achieving or fail to achieve compliance with these certifications and standards, or our competitors achieve compliance with these certifications and standards, we may be disqualified from selling our products to such governmental entities, or be at a competitive disadvantage, which would harm our business, results of operations, and financial condition. There are no assurances that we will find the terms for obtaining such certifications to be acceptable or that we will be successful in obtaining or maintaining the certifications.



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 and inclusion on government contract vehicles, which affect how we and our partners do business with government agencies. Government contracts 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. These rights and remedies allow government customers, among other things, to terminate existing contracts for convenience and/or with short notice and without cause, and whether a government contract or grant might be terminated by the government under such a provision is outside of our control and could adversely affect our revenue. As a result of actual or perceived noncompliance with government contracting laws, regulations, or contractual provisions, we may be subject to non-ordinary course audits and internal investigations which may prove costly to our business financially, divert management time, or limit our ability to continue selling our products and services to our government customers. These laws and regulations may impose other added costs on our business, and failure to comply with these or other applicable regulations and requirements, including non-compliance in the past, could lead to claims for damages from our partners, downward contract price adjustments or refund obligations, civil or criminal penalties, and termination of contracts and suspension or debarment from obtaining government contracts and grants for a period of time with government agencies. Any such damages, penalties, disruption, or limitation in our ability to do business with a government could have a material adverse effect on our business, results of operations, financial condition, public perception and growth prospects.

We are subject to multiple environmental permitting processes at the national, sub-national, and/or local level. Failure to obtain key permits and approvals may adversely impact our business.

Our facilities are subject to local, state and federal siting and environmental permitting requirements. Permitting agencies with discretionary authority may refuse to issue required permits, forcing consideration of alternative sites, or may impose costly permit conditions. Such actions could increase the cost, or lengthen the timeline, of developing additional manufacturing facilities.

Even if we successfully navigate our way through the permitting phases, future conflicts may arise in the course of our development activities, including restrictions on our actions due to new or evolving environmental legislation, changes in permitted uses and conflicts with non-governmental organizations regarding the use of land for our manufacturing facilities. If such conflicts arise, we may be delayed or prevented from building our research and development and manufacturing facilities, which could have a negative impact on our financial condition, prospects, and results of operations.

We are subject to anti-corruption and anti-bribery laws and anti-money laundering laws, and non-compliance with such laws can subject us to administrative, civil and criminal fines and penalties, collateral consequences, remedial measures and legal expenses, all of which could adversely affect our business, results of operations, financial condition and reputation.

We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, and possibly other anti-bribery and anti-corruption laws and anti-money laundering laws in various jurisdictions in which we conduct, or in the future may conduct, activities. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years and are interpreted broadly to generally prohibit us and our officers, directors, employees, business partners, agents, representatives and third-party intermediaries from corruptly offering, promising, authorizing or providing, directly or indirectly anything of value to recipients in the public or private sector.

We may leverage third parties to sell our products and conduct our business abroad. We, our officers, directors, employees, business partners, agents, representatives and third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and may be held liable for the corrupt or other illegal activities of these employees, agents, representatives, business partners or third-party intermediaries even if we do not explicitly authorize such activities. We cannot assure you that all of our officers, directors, employees, business partners, agents, representatives and third-party intermediaries will not take actions in violation of applicable law, for which we may be ultimately held responsible. If we conduct international sales and business, our risks under these laws may increase.

These laws also require companies to make and keep books, records and accounts that accurately reflect transactions and dispositions of assets and to maintain a system of adequate internal accounting controls and compliance procedures designed to prevent any such actions. While we have certain policies and procedures to address compliance with such laws, we cannot assure you that none of our officers, directors, employees, business partners, agents, representatives and third-party intermediaries will take actions in violation of our policies and applicable law, for which we may be ultimately held responsible.



A violation of these laws or regulations could adversely affect our business, results of operations, financial condition and reputation. Our policies and procedures designed to ensure compliance with these regulations may not be sufficient and our directors, officers, employees, representatives, consultants, agents, and business partners could engage in improper conduct for which we may be held responsible.

Any allegations or violation of the FCPA or other applicable anti-bribery and anti-corruption laws and anti-money laundering laws could subject us to whistleblower complaints, adverse media coverage, investigations, settlements, prosecutions, enforcement actions, fines, damages, loss of export privileges, and severe administrative, civil and criminal sanctions, suspension or debarment from government contracts, collateral consequences, remedial measures and legal expenses, all of which could materially and adversely affect our business, results of operations, prospects, financial condition and reputation. Responding to any investigation or action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and other professional fees.

Changes in laws or regulations, or a failure to comply with any laws or regulations, may adversely affect our business, investments and results of operations.

We are subject to laws and regulations enacted by national, regional and local governments. In particular, we are required to comply with certain SEC and other legal requirements. Compliance with, and monitoring of, applicable laws and regulations may be difficult, time consuming and costly. Those laws and regulations and their interpretation and application may also change from time to time and those changes could have a material adverse effect on our business, investments and results of operations. In addition, a failure to comply with applicable laws or regulations, as interpreted and applied, could have a material adverse effect on our business and results of operations.

As a result of plans to expand our business operations, including to jurisdictions in which tax laws may not be favorable, our obligations may change or fluctuate, become significantly more complex or become subject to greater risk of examination by taxing authorities, any of which could adversely affect our after-tax profitability and financial results.

Our effective tax rates may fluctuate widely in the future, particularly if our business expands domestically or internationally. Future effective tax rates could be affected by operating losses in jurisdictions where no tax benefit can be recorded under GAAP, changes in deferred tax assets and liabilities, or changes in tax laws. Factors that could materially affect our future effective tax rates include, but are not limited to: (i) changes in tax laws or the regulatory environment, (ii) changes in accounting and tax standards or practices, (iii) changes in the composition of operating income by tax jurisdiction and (iv) pre-tax operating results our business.

Additionally, we may be subject to significant income, withholding, and other tax obligations in the United States and may become subject to taxation in numerous additional U.S. state and local and non-U.S. jurisdictions with respect to income, operations and subsidiaries related to those jurisdictions. Our after-tax profitability and financial results could be subject to volatility or be affected by numerous factors, including (i) the availability of tax deductions, credits, exemptions, refunds and other benefits to reduce tax liabilities, (ii) changes in the valuation of deferred tax assets and liabilities, if any, (iii) the expected timing and amount of the release of any tax valuation allowances, (iv) the tax treatment of stock-based compensation, (v) changes in the relative amount of earnings subject to tax in the various jurisdictions, (vi) the potential business expansion into, or otherwise becoming subject to tax in, additional jurisdictions, (vii) changes to existing intercompany structure (and any costs related thereto) and business operations, (viii) the extent of intercompany transactions and the extent to which taxing authorities in relevant jurisdictions respect those intercompany transactions, and (ix) the ability to structure business operations in an efficient and competitive manner. Outcomes from audits or examinations by taxing authorities could have an adverse effect on our after-tax profitability and financial condition. Additionally, the IRS and several foreign tax authorities have increasingly focused attention on intercompany transfer pricing with respect to sales of products and services and the use of intangibles. Tax authorities could disagree with our intercompany charges, cross-jurisdictional transfer pricing or other matters and assess additional taxes. If we do not prevail in any such disagreements, our profitability may be affected.

Our after-tax profitability and financial results may also be adversely affected by changes in relevant tax laws and tax rates, treaties, regulations, administrative practices and principles, judicial decisions and interpretations thereof, in each case, possibly with retroactive effect.



Changes to applicable tax laws and regulations or exposure to additional income tax liabilities could affect our business and future profitability.

We are a U.S. corporation and thus subject to U.S. corporate income tax on our worldwide income. Further, our operations and customers are primarily located in the United States, and, as a result, we are subject to various U.S. federal, state and local taxes. U.S. federal, state and local and non-U.S. tax laws, policies, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us and may have an adverse effect on its business and future profitability.

For example, several tax proposals have been set forth that would, if enacted, make significant changes to U.S. tax laws. Congress may consider, and could include, some or all of these proposals in connection with tax reform that may be undertaken. It is unclear whether these or similar changes will be enacted and, if enacted, how soon any such changes could take effect. The passage of any legislation as a result of these proposals and other similar changes in U.S. federal income tax laws could adversely affect our business and future profitability.

## Risks Related to our Common Stock and the Warrants

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales could occur, could cause the market price of our common stock to drop significantly.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock.

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

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

The trading market for our common stock and warrants will be 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 the analysts who may cover us change their recommendation regarding our common stock adversely, or provide more favorable relative recommendations about our competitors, the price of our common stock and warrants would likely decline. If any analyst who may cover us were to cease their coverage or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

We may issue additional common stock under an employee incentive plan or an employee stock purchase plan or preferred stock. Any such issuances would dilute the interest of our stockholders and likely present other risks.

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

- may significantly dilute the equity interests of our investors;

- may subordinate the rights of holders of common stock if preferred stock is issued with rights senior to those afforded our common stock;

- could cause a change in control if a substantial number of shares of our common stock are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors; and

- may adversely affect prevailing market prices for our common stock and/or warrants.



Delaware law and provisions in our Second A&R Charter and Bylaws might delay, discourage or prevent a change in control of the Company or changes in our management, thereby depressing the market price of our common stock and warrants.

Our status as a Delaware corporation and the anti-takeover provisions of the 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, the Second A&R Charter and our Bylaws contain provisions that may make the acquisition of us more difficult or delay or prevent changes in control of our management. Among other things, these provisions:

- provide advance notice procedures with regard to stockholder nominations of candidates for election as directors or other stockholder proposals to be brought before meetings of our stockholders, which may preclude our stockholders from bringing certain matters before meetings of our stockholders;

- provide the Board the ability to authorize issuance of preferred stock in one or more series, which makes it possible for the Board to issue, without our stockholder’s approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of Solid Power and which may have the effect of deterring hostile takeovers or delaying changes in control or management of Solid Power;

- provide that the Board be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three-year terms;

- a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

- provide that certain provisions of our Second A&R Charter can only be amended or repealed by the affirmative vote of the holders of at least 66 2/3% in voting power of the outstanding shares of our common stock entitled to vote thereon, voting together as a single class;

- provide that certain provisions of our Bylaws can be altered or repealed by (i) the Board or (ii) our stockholders upon the affirmative vote of 66 2/3% of the voting power of our common stock outstanding and entitled to vote thereon, voting together as a single class;

- only the Board (pursuant to a majority vote) or the Chairperson of the Board may call a special meeting; and

- the designation of Delaware and federal courts as the exclusive forum for certain disputes.

Our Bylaws designate state courts within 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, our Second A&R Charter or our 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 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.

Our Bylaws provide that the exclusive forum provision will be applicable to the fullest extent permitted by applicable law. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision does not apply to suits brought to enforce any duty or liability created by the Exchange Act or any rule or regulation promulgated thereunder (in each case, as amended), or any other claim over which the federal courts have exclusive jurisdiction.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. Alternatively, if a court were to find the choice of forum provision contained 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 harm our business, operating results and financial condition.

There is no guarantee that the Public Warrants will be in the money at the time they become exercisable, and they may expire worthless.

The exercise price for each of our Public Warrants and Private Placement Warrants is $11.50 per share of common stock. There is no guarantee that the Public Warrants will be in the money following the time they become exercisable and prior to their expiration, and as such, the Public Warrants may expire worthless.

We may amend the terms of the warrants in a manner that may be adverse to holders of Public Warrants 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). As a result, the exercise price of the warrants could be increased, the exercise period could be shortened and the number of shares of our common stock purchasable upon exercise of a warrant could be decreased, all without any specific holder’s approval.

Our warrants were issued in registered form under our warrant agreement with Continental Stock Transfer & Trust Company, as warrant agent. The warrant agreement 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 change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms of the Public 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 Public Warrants with the consent 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 6. [Reserved]

## 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 “Special 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, particularly in “Risk Factors.” 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

We are developing solid state battery technologies to enable the next generation of rechargeable batteries for the fast-growing EV and other markets.

Our core technology is our proprietary sulfide-based solid electrolyte material, which replaces the liquid or gel electrolyte used in conventional lithium-ion batteries. We believe that our electrolyte material can enable extended driving range, longer battery life, improved safety, and lower costs compared to conventional lithium-ion.

We also are designing and developing solid state cells that utilize our electrolyte in the cathode, anode, and separator layers. We currently produce 0.2 Ah, 2 Ah, 20 Ah, and EV cells on two pilot lines using established manufacturing processes. In 2022, we installed our EV line, which allows us to produce EV cells between 60 Ah and 100 Ah. The EV line is designed to produce cells as part of the automotive qualification process and for vehicle integration demonstration purposes.

We have partnered with industry leaders, including Ford, BMW, and SK On. We are working closely with each of these partners to refine and validate our cell designs and electrolyte material with the ultimate goal to commercialize our technologies. Our business model – selling our electrolyte to cell manufacturers and licensing our cell designs and manufacturing processes – distinguishes us from many of our competitors who plan to be commercial battery manufacturers. Ultimately, we endeavor to be a leading producer and distributor of sulfide-based solid electrolyte material for powering both EVs and other applications. Since we do not intend to commercially produce battery cells, we expect to invest less than other development-stage battery companies that plan to commercially manufacture their own cell designs and construct battery production facilities.

The products we currently make are in the development stage and require continued development and validation before we can commercialize either our electrolyte or cell technology.

## The Business Combination

The business combination was accounted for as a reverse recapitalization, in accordance with GAAP. Under this method of accounting, DCRC was treated as the “acquired” company for financial reporting purposes. Accordingly, the business combination was treated as the equivalent of Legacy Solid Power issuing stock for the net assets of DCRC, accompanied by a recapitalization, whereby no goodwill or other intangible assets was recorded. Operations prior to the business combination are those of Legacy Solid Power. While DCRC was the legal acquirer, because Legacy Solid Power was deemed the accounting acquirer, the historical financial statements of Legacy Solid Power became the historical financial statements of the combined company upon the consummation of the business combination.

As a result of the business combination, we became a Nasdaq-listed company, which will require that we continue to hire additional personnel and implement procedures and processes to address public company regulatory requirements and customary practices. We expect to incur additional annual expenses as a public company for, among other things, directors’ and officers’ liability insurance, director fees, additional internal and external accounting, legal, administrative resources, and increased audit, compliance, and legal fees.



Our results of operations and statements of assets and liabilities may not be comparable between periods as a result of the business combination.

## 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 for us but also pose material risks and challenges, including those discussed in “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements,” appearing in this Report, which are incorporated by reference.

Prior to reaching commercialization, we must test and validate our products to ensure they meet the performance and safety requirements of our customers. We also will have to negotiate licensing and supply contracts with our customers on terms and conditions that are mutually acceptable. We will need to scale production of our electrolyte material to satisfy anticipated demand. 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 we currently anticipate.

Our revenue generated to date has primarily come from research and development performance on government contracts and research and development licensing activities. We have and are deploying substantial capital to expand our production capabilities and engage in research and development programs. We also expect to incur significantly more administrative expenses as a publicly traded company than we did previously.

In addition to meeting our development goals, commercialization, and future growth and demand for our products is 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 to date have been limited and were conducted primarily in the United States. Our historical results are reported under GAAP and in U.S. dollars.



## Results of Operations

The following table is a consolidated summary of our operating results for the periods indicated:

## NM = Not meaningful

The key factors driving our 2022 increase in operating loss were as follows:

- Revenue and direct costs – our overall revenue and related direct costs increased as a result of additional performance under our JDAs and government contracts, as well as additional product sales.

- Research and development – our research and development costs increased primarily as a result of increased labor costs and material consumption as we expanded the development efforts of our battery cells and electrolyte material. We expect our development costs to continue to increase as we continue to accelerate both the pace and scope of our development efforts.

- General and administrative – our general and administrative costs increased primarily as a result of increased headcount to support our operational and organizational capabilities, professional service fees, insurance costs, and labor resources as a result of our public company status and to support our growth. We continue to expect our general and administrative costs to increase as a result of additional planned hiring and increased public company compliance costs.

- Non-cash stock compensation costs increased across Direct costs, Research and development, and General and administrative expenses related to increased labor costs.

- Nonoperating income – our nonoperating income increased primarily due to increased interest income following strategic cash investments, and the absence of other expense related to the buyout and termination of a manufacturing rights agreement, offset by a decrease in the gain on fair value adjustment of warrant liabilities.

## NM = Not meaningful

The key factors driving our 2021 increase in operating loss were as follows:

- Revenue and direct costs – our overall revenue and related direct costs increased, however we saw an increase in revenue from governmental contracts and corresponding decrease to commercial revenues driven by the timing of program execution.

- Research and development – our research and development costs increased primarily as a result of increased labor costs and material consumption as we expanded the development efforts of our solid-state battery cells and electrolyte material.

- Marketing and sales – our marketing and sales costs increased as a result of increased labor costs and an expansion of our sales and marketing efforts.

- General and administrative – our general and administrative costs increased primarily as a result of professional service fees and labor costs as a result of our public company status. We expect our general and administrative costs to increase as a result of increased public company costs and requirements.

- Nonoperating income – our nonoperating income increased as a result of the gain on fair value adjustment of warrant liabilities, loss from change in fair value of embedded derivative liability, and other expense related to the buyout and termination of a manufacturing rights agreement.

## Liquidity and Capital Resources

## Sources of Liquidity

Our sources of cash have historically been primarily derived from the sale of equity and the business combination, with a small portion coming from performance on government contracts and commercial revenues.



As of December 31, 2022 and 2021, we had $496.1, and $589.3 million of total liquidity, respectively, as set forth below:

<table><tr><td>(in thousands)</td><td>December 31, 2022</td><td>December 31, 2021</td></tr><tr><td>Cash and cash equivalents</td><td>$ 50,123</td><td>$ 513,447</td></tr><tr><td>Marketable securities</td><td>272,957</td><td>75,885</td></tr><tr><td>Long-term investments</td><td>172,974</td><td>—</td></tr><tr><td>Total liquidity</td><td>$ 496,054</td><td>$ 589,332</td></tr></table>

## Short-Term Liquidity Requirements

We anticipate that our most significant capital expenditures in 2023 will relate to finishing construction of our electrolyte facility, and enhancing production capabilities at this facility and our cell manufacturing lines. In addition, our short-term liquidity requirements include operating and capital expenses needed to further our development programs and to optimize our pilot production lines and electrolyte manufacturing capabilities. We expect to fund our short-term liquidity requirements through our cash on hand and other liquid assets.

We anticipate our total combined capital and operational expenditures for 2023 will be between $50 million and $60 million, which includes approximately $1.45 million for the payment of contractual cash obligations as of December 31, 2022, primarily related to payments for operating leases.

## Long-Term Liquidity Requirements

We believe that our cash on hand is sufficient to meet our operating cash needs (including expenditures for the increased pace and scope of development as well as increased public company costs), working capital and capital expenditure requirements for a period of at least the next 12 months and longer term until we generate adequate cash flows from licensing activities and/or electrolyte sales.

We may, however, need additional cash if there are material changes to our business conditions or other developments, including changes to our operating plan, development progress, delays in negotiations with OEMs, cell manufacturers or other suppliers, market adoption of EVs, supply chain challenges, competitive pressures, inflation, and regulatory developments. 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 the 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.

Our cash investment policy is designed to provide flexibility in investment options. Our investment policy is designed primarily to maintain adequate liquidity to fund future operations, research and development, and anticipated capital expenditures, with a secondary goal to maximize yield on cash not required to be liquid for near term operations.

Cash used in operating activities increased from 2021 to 2022 primarily attributable to our operating loss, which was driven by continued increase in research and development costs and general and administrative expenses. We continue to expect cash flows used in operating activities to increase as we accelerate both the pace and scope of our development efforts, and work to achieve commercialization of our products. We continue to anticipate increased expenditures for general and administrative functions in connection with our status as a public company and to support growth of our development efforts.

Cash used in operating activities increased from 2020 to 2021. This increase in cash use was primarily attributable to our operating loss related to similar increases in research and development costs and general and administrative expenses.

## Cash flows used in investing activities:

Cash used in investing activities increased from 2021 to 2022 primarily due to capital expenditures, investments in patents, and the net effect of the purchase and sales of marketable securities. Capital expenditures were primarily for custom manufacturing equipment in connection with our expansion of electrolyte production capabilities and installation of our EV line. We continue to expect cash used in investing activities to increase as we finalize the build out of our electrolyte production facility and increase its production capabilities, and as we increase our electrolyte production scale. Each of our locations will continue to require investment in specialized equipment to facilitate the manufacturing process of our electrolyte material and battery cells. As our production processes are scaled in the future, especially with respect to our electrolyte material, we expect capital expenditures to increase.

Cash used in investing activities increased from 2020 to 2021 due to increases in capital expenditures and purchases of marketable securities in 2021. Capital expenditures were primarily for custom manufacturing equipment in connection with our expansion of electrolyte production.

## Cash flows provided by financing activities:

Net cash provided by financing activities for the year ended December 31, 2022 was primarily from the cash exercise of stock options. Net cash provided by financing activities for the year ended December 31, 2021 were primarily the proceeds from the business combination and the Series B Financing. Net cash provided by financing activities for the year ended December 31, 2020 were primarily from the sale of convertible notes and proceeds from a bank term loan, which was retired in December of 2021.

## 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 upon 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.



Valuation of Private Placement Warrant Liability

<table><tr><td>Description</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>The private placement warrant liability is classified as a liability, in accordance with ASC Topic 815, as they do not satisfy the criteria to be classified as equity based on the indexation criteria. Public and private warrants are recorded at their fair value at the date of issuance, and subsequently remeasured at each reporting period end. Any change in value is recognized through the consolidated statement of operations.</td><td>Valuation of private placement warrants requires that we make significant judgments and assumptions related to the fair value based on the Black-Scholes model including term, stock price, volatility and the selection of guideline public companies, risk free rate and dividend yield.</td><td>If we were to change our judgments or estimates used in valuation of private warrants, it could cause a material increase or decrease to the gain or loss realized from the change in fair value of private placement warrants, and to the underlying warrant liability.</td></tr></table>

<table><tr><td>Stock-Based Compensation</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>Description</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>We record stock-based compensation expense according to the provisions of ASC Topic 718 - Stock Compensation. ASC Topic 718 requires all share-based awards to employees, including grants of employee stock options, restricted stock units, and shares purchased through the Company’s ESPP Plan to be recognized in the financial statements based on their fair values.</td><td>Under the provisions of ASC Topic 718, we determine the appropriate fair value model to be used for valuing share-based issuances and the amortization method for recording compensation cost, which can be impacted by the following assumptions:  ·expected term  ·expected volatility  ·expected dividend yield  ·risk-free interest rate</td><td>If we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of stock-based compensation expense reported.</td></tr><tr><td>The grant date fair value of Legacy Solid Power’s common stock was historically determined by its board of directors with the assistance of management and an independent valuation.</td><td></td><td></td></tr><tr><td>As of December 9, 2021, our common stock is publicly traded, and the fair value is based on the closing market price on the date grants are made.</td><td></td><td></td></tr></table>



Collaborative Revenue

<table><tr><td>Description</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>We recognize revenue from our research and development collaboration agreements representing joint operating activities in accordance with ASC Topic 808, Collaborative Arrangements. The elements of the collaboration agreements in which both parties to the contract are active participants and to which both parties are exposed to significant risks and rewards that are dependent on the commercial success of the efforts under the contract are recorded as collaborative arrangements.</td><td>Our revenue recognition accounting methodology requires us to make significant estimates and assumptions, and to apply professional judgment. Collaborative revenues from cost-based contracts are recognized based on costs incurred during each period plus any earned fee. Contract costs include all direct labor, subcontract costs, costs for materials and indirect costs related to the contract performance that are allowable under the provisions of the contract. Collaborative revenues from fee-based contracts are recognized based on costs incurred to meet contractually defined milestones and deliverables along with our assessment of achievement of those measurable deliverables under the contract or based on appropriate over time methods.</td><td>If we were to change our judgments or estimates, it could cause a material increase or decrease in the amount of revenue or deferred revenue that we report in a particular period.</td></tr></table>

<table><tr><td>Leases</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>Description</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>Under ASC 842, at contract inception we determine if an arrangement meets the definition of a lease, as either operating or financing leases. At lease commencement, we record and recognize right-of-use assets for the lease liability amount and initial direct costs incurred, offset by lease incentives received. We record lease liabilities for the net present value of future lease payments over the lease term. The discount rate we use is generally our estimated incremental borrowing rate unless the lessor&#x27;s implicit rate is readily determinable. We calculate discount rates periodically to estimate the rate we would pay to borrow the funds necessary to obtain an asset of similar value, over a similar term, with a similar security.</td><td>Judgments made by management for our lease obligations include the determination of our incremental borrowing rate and the length of the lease term, which includes the determination of renewal options that are reasonably assured. We use our estimated incremental borrowing rate in determining the present value of lease payments for purposes of determining lease classification and recording lease liabilities and lease assets on our consolidated balance sheets. Our incremental borrowing rate is determined based on a synthetic credit rating, determined using a valuation model, adjusted to reflect a secured credit rating and a developed spread curve, if applicable, applied to a risk-free rate yield curve. The lease term can affect the classification of a lease as finance or operating for accounting purposes, the amount of the lease liability and corresponding right-of-use lease asset recognized, the term over which related leasehold improvements for each facility are amortized and any</td><td>These judgments may produce materially different amounts of depreciation, amortization and rent expense, right-of-use assets, and lease liabilities than would be reported if different assumed lease terms were used.</td></tr></table>



<table><tr><td colspan="3">Leases</td></tr><tr><td>Description</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td></td><td>rent holidays and/or changes in rental amounts for recognizing rent expense over the term of the lease.</td><td></td></tr><tr><td colspan="3">Research and Development</td></tr><tr><td>Description</td><td>Judgments and Uncertainties</td><td>Effect if Results Differ From Assumptions</td></tr><tr><td>Our Company is in the research and development phase. Our product offering relies heavily on new technology currently undergoing development and does not yet meet standard specifications to be sold commercially. Therefore, all related costs are currently accounted for as part of research and development expense. The criteria established by the Company to determine when commercialization has been reached includes the length of time the units have been operational in the field and the level of performance at which those units operate. As we transition from the research and development phase and into a full commercial phase, all inventoriable costs will be capitalized. As of December 31, 2022, the criteria for commercialization have not yet been met.</td><td>Research and development costs require us to make judgments regarding our progress toward commercialization. We routinely assess this progress to prepare for the change in cost treatment.</td><td>If we were to change our judgment regarding research and development costs or our progress toward commercialization, it could cause a material change in cost treatment.</td></tr></table>

## Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed, or anticipate in the future to be exposed, to a variety of market and other risks including credit risks, and foreign currency translation and transaction risks as well as risks relating to the availability of funding sources, hazard events and specific asset risks.

## Credit Risk

Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash, accounts receivable, and marketable securities. Domestic cash deposits exceeded the Federal Deposit Insurance Corporation insurable limit at December 31, 2022 and December 31, 2021. We have not experienced any losses on our cash deposits to date.

Furthermore, for the year ended December 31, 2022, 82% of our revenues came from contracts with four customers, and for the year ended December 31, 2021, 87% of our revenues came from contracts with four customers. We are subject to non-payment or non-performance of these counterparties, and we generally do not require collateral from our customers. We evaluate the collectability of our accounts receivable and provide an allowance for potential credit losses as necessary. To date, we have not experienced any customer credit losses.

# Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Solid Power, Inc.

## Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Solid Power, Inc. (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2022, 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, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 2013 framework, and our report dated March 1, 2023 expressed an unqualified opinion thereon.

## 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 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. 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.

## Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.



## Valuation of Private Placement Warrant Liability

Description of the Matter The fair value of the Private Placement Warrant Liability at December 31, 2022, was $4.2 million. During the year ended December 31, 2022, the fair value of the Private Placement Warrant Liability decreased by $19.3 million. As discussed in Note 8 to the consolidated financial statements, the fair value of the Private Placement Warrant Liability was estimated using a Black-Scholes model that utilized various assumptions, including term, stock price, volatility, risk free rate and dividend yield. Changes to the fair value of the Private Placement Warrant Liability are included within the Consolidated Statement of Operations. The volatility assumption significantly affects the fair value of the Private Placement Warrant Liability. The volatility is estimated based on implied volatility from the Company's Public Warrants and from historical volatility of select peer companies' common stock that matches the expected remaining life of the warrants.

Auditing the fair value of the Private Placement Warrant Liability was challenging due to the judgmental nature of selecting an appropriate valuation model and the model’s assumptions, especially the guideline public companies used to determine the volatility assumption.

How We Addressed the Matter in Our Audit To test the fair value of the Private Placement Warrant Liability, our audit procedures included, among others, assessing the appropriateness of the use of the Black-Scholes model and accuracy of the underlying calculation, including testing the assumptions used to calculate the fair value of the Private Placement Warrant Liability. We compared the term, stock price, risk free rate and dividend yield to readily available information as of the valuation date at December 31, 2022. For the volatility assumption, we assessed the suitability of the peer companies used based on the similarity of their operations to that of the Company and developed an independent range of volatility based on the implied volatility of the Company’s Public Warrants and historical volatilities of the similarly sized peer companies. We involved our specialists to assist us with evaluating the Black-Scholes model, as well as to perform comparative range calculations using the assumptions previously discussed.

# Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Solid Power, Inc.

## Opinion on Internal Control Over Financial Reporting

We have audited Solid Power, Inc.'s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 2013 framework (the COSO criteria). In our opinion, Solid Power, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of operations, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and our report dated March 1, 2023 expressed an unqualified opinion thereon.

## Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

## Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

# Notes to Consolidated Financial Statements

## Note 1 – Nature of Business

Solid Power, Inc. (the “Company”) is developing solid state battery technology to enable the next generation of batteries for the fast-growing EV and other markets. The Company’s planned business model is to sell its sulfide-based solid electrolyte and to license its solid-state cell designs and manufacturing processes. For the years ended December 31, 2022, 2021, and 2020, the Company has not derived material revenue from its principal business activities.

On December 8, 2021 (the “Closing Date”), the Company (f/k/a Decarbonization Plus Acquisition Corporation III (“DCRC”)) consummated its previously announced business combination pursuant to the Business Combination Agreement and Plan of Reorganization, dated June 15, 2021 (as amended, the “Business Combination Agreement”), among the Company, DCRC Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of DCRC (“Merger Sub”), and Solid Power Operating, Inc., a Colorado corporation (f/k/a Solid Power, Inc., “Legacy Solid Power”). Pursuant to the terms of the Business Combination Agreement, Merger Sub merged with and into Legacy Solid Power, with Legacy Solid Power surviving the merger as a wholly owned subsidiary of the Company (the “Merger” and, together with the other transactions contemplated by the Business Combination Agreement, the “Business Combination”).

## Note 2 – Significant Accounting Policies

## Basis of Presentation and Principles of Consolidation

The Consolidated Financial Statements of the Company have been prepared on the basis of generally accepted accounting principles in the United States (“GAAP”). The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the Consolidated Financial Statements. Actual results could differ from those estimates. All amounts presented in the footnotes are in thousands, except share and per share amounts.

Pursuant to the Business Combination Agreement, the merger between Merger Sub and Legacy Solid Power was accounted for as a reverse recapitalization in accordance with GAAP (the “Reverse Recapitalization”). Under this method of accounting, DCRC was treated as the “acquired” company and Legacy Solid Power is treated as the acquirer for financial reporting purposes.

Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Legacy Solid Power issuing stock for the net assets of DCRC, accompanied by a recapitalization. The net assets of DCRC are stated at historical cost, with no goodwill or other intangible assets recorded.

The consolidated assets, liabilities, and results of operations prior to the Reverse Recapitalization are those of Legacy Solid Power. The shares and corresponding capital amounts and losses per share, prior to the Business Combination, have been retroactively restated based on the Exchange Ratio (defined below).

The Consolidated Financial Statements include accounts of the Company and its wholly owned subsidiary, Solid Power Operating, Inc. All intercompany balances and transactions have been eliminated in consolidation.

The accompanying Consolidated Financial Statements have been prepared assuming that the Company will continue as a going concern.

## Segment Reporting

The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer. The Company has determined that it operates in one operating segment and one reportable segment, as the CODM reviews financial information presented as a single entity for purposes of making operating decisions, allocating resources, and evaluating financial performance.



## Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingencies at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting periods. Estimates made by the Company include, but are not limited to, those related to the valuation of common stock prior to the Business Combination, valuation of stock warrants, and useful lives of long-term assets, among others. The Company bases these estimates on historical experience and other assumptions that it believes are reasonable under the circumstances.

## Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. As of December 31, 2022 and periodically throughout the year, the Company’s cash accounts exceeded federally insured limits.

## Marketable Securities

The Company’s investment policy is consistent with the definition of available-for-sale securities. The Company does not buy and hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity, and return. From time to time, the Company may sell certain securities, but the objectives are not to generate profits on short-term differences in price.

These securities are carried at estimated fair value with unrealized holding gains and losses included in other comprehensive loss in stockholders' deficit until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Dividend and interest income are recognized when earned.

## Contract Receivables

Contract receivables consist of amounts due from government entities and commercial contractors. Management considers all contract receivables collectible, and therefore, an allowance for doubtful accounts has not been recorded as of December 31, 2022 and 2021. Included within contract receivables are amounts for work performed but not billed as of December 31, 2022 and 2021, shown below.

<table><tr><td>Contract receivables not billed</td><td>December 31, 2022</td><td>December 31, 2021</td></tr><tr><td></td><td>$ 1,083</td><td>$ 310</td></tr></table>

## Credit Risk and Major Customers

Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents, marketable securities, and long-term investments. The Company seeks to mitigate its credit risk with respect to cash and cash equivalents, marketable securities, and long-term investments by making deposits with several large, reputable financial institutions and investing in high credit rated instruments.

The Company grants credit in the normal course of business to government entities and commercial contractors in the United States. The Company periodically performs credit analyses and monitors the financial condition of its customers to reduce credit risk. The Company performs ongoing credit evaluations of its customers, but generally does not require collateral to support contract receivables.

## Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consist primarily of security deposits, prepaid Directors and Officers insurance and other minor miscellaneous expenses paid in advance.

## Property and Equipment

Property and equipment are recorded at cost. The Company capitalizes property and equipment with useful lives exceeding one year. Assets are depreciated over their estimated useful lives. The straight-line method is used for computing depreciation and amortization. Depreciation and amortization expenses are recorded within the Direct costs and Research and development line items in the Consolidated Statements of Operations. Cost of maintenance and repairs are charged to expense when incurred. Construction in progress related to specialized equipment will be reclassified as Property and equipment and depreciated, once placed in service.

<table><tr><td></td><td>Depreciable Life - Years</td></tr><tr><td>Commercial production equipment</td><td>5 years</td></tr><tr><td>Laboratory equipment</td><td>5 years</td></tr><tr><td>Furniture and Computer Equipment</td><td>3-7 years</td></tr><tr><td>Leasehold improvements</td><td>Lesser of asset life or lease term</td></tr></table>

## Long-Term Investments

The Company considers all investments with an original maturity of twelve months or more when purchased to be long-term investments.

## Intangible Assets

Intangible assets consist of licenses and costs incurred for pending patents and pending trademarks. Licenses consist of rights to use patents and are amortized over their estimated useful life of three to 20 years. Patent and trademark costs are amortized over an estimated useful life upon award by the United States Patent and Trademark Office or expensed if the Company is unsuccessful in securing an issued patent. Intangible assets that are subject to amortization are reviewed for potential impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. Assets not subject to amortization are tested for impairment if events or circumstances indicate an impairment may have occurred at least annually.

## Deferred Rent

Prior to the adoption of ASU No. 2016-02, Leases (Topic 842) on January 1, 2022, the Company had entered into operating lease agreements for each of its two facilities, each of which contains provisions for future rent increases or periods in which rent payments are reduced. The Company records monthly rent expense equal to the total of the payments due over the lease term, divided by the number of months of the lease term. The difference between rent expense recorded and the amount paid is credited or charged to deferred rent, which is reflected in Other Long-term Liabilities in the accompanying Consolidated Balance Sheets. Deferred rent also includes the unamortized portion of landlord-financed tenant improvement allowances, which are amortized on a straight-line basis over the lease term as a reduction in rent expense.

## Leases

The Company accounts for its leases under ASU No. 2016-02, Leases (Topic 842). Under this guidance, the Company classifies contracts meeting the definition of a lease as operating or financing leases, and leases are recorded on the condensed consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term. For finance leases, interest on the lease liability and the amortization of the right-of-use asset results in front-loaded expense over the lease term. Variable lease expenses, including common maintenance fees, insurance and property tax, are recorded when incurred.



In calculating the right-of-use asset and lease liability, the Company elects to combine lease and non-lease components for all classes of assets. The Company excludes short-term leases having initial terms of 12 months or less as an accounting policy election, and instead recognizes rent expense on a straight-line basis over the lease term.

## Stock-based Compensation

The Company recognizes expenses for employee services received in exchange for stock-based compensation based on the grant date fair value of the awards. The determination of the estimated fair value of stock-based payment awards on the date of grant using the Black-Scholes option-pricing model is affected by the Company’s stock price, as well as assumptions regarding risk-free rate, dividend yield, and the historical volatility of comparable entities. Stock-based compensation is recorded as an expense only for those awards that are expected to vest. Compensation cost is recognized on a straight-line basis over the requisite vesting service period and is allocated ratably within Operating Expenses in the Consolidated Statements of Operations.

## Revenue

The Company records the elements of its joint development agreements that represent joint operating activities in accordance with Accounting Standards Codification (ASC) Topic 808, Collaborative Arrangements. Accordingly, the elements of the joint development agreements that represent activities in which both parties are active participants and to which both parties are exposed to the significant risks and rewards that are dependent on the commercial success of the activities are recorded as collaborative arrangements. The Company considers the guidance in ASC 606-10-15, Revenue from Contracts with Customers – Scope and Scope Exceptions, in determining the appropriate treatment for the transactions between the Company and its partners and the transactions between the Company and third parties. Generally, the classification of transactions under the joint development agreements is determined based on the nature and contractual terms of the arrangement along with the nature of the operations of the participants. The Company recognizes collaborative revenue from cost contracts on the basis of costs incurred during the period and cost plus fixed-fee contracts on the basis of costs incurred during the period plus the fee earned. Contract costs include all direct labor, subcontract, material, and indirect costs related to the contract performance that are allowable under contract provisions.

Unbilled receivables are included in contract receivables and represent revenue recognized for which billings have not yet been presented to customers. Deferred revenue represents billings in advance of revenue recognized. Deferred revenue as of December 31, 2022 and 2021 was $4,050 and $500, respectively.

## Beneficial Conversion Feature and Embedded Derivatives

The beneficial conversion feature (the “BCF”) of a convertible note is normally characterized as the convertible portion or feature of certain notes payable that provide a rate of conversion that is below market value or in-the-money when issued. For convertible debt where the rate of conversion is below market value, the Company records a BCF and related debt discount. When Legacy Solid Power recorded a BCF, the intrinsic value of the BCF was recorded in equity to Additional paid-in capital and the difference between the debt proceeds and the BCF was a debt discount against the face amount of the respective debt instrument and amortized to interest expense over the life of the debt. A separate embedded derivative was recognized as a derivative liability that was subsequently adjusted to fair value at each Consolidated Balance Sheet date.

Embedded derivatives that are required to be bifurcated from the underlying debt instrument (i.e., host) are accounted for and valued as separate financial instruments. Legacy Solid Power evaluated the terms and features of its 2020 convertible promissory notes (as defined below) and identified embedded derivatives requiring bifurcation and accounting at fair value, using the valuation techniques mentioned in the Fair Value Measurements section of this Note, because the economic and contractual characteristics of the embedded derivatives met the criteria for bifurcation and separate accounting due to the instruments containing mandatory redemption features that were not clearly and closely related to the debt host instrument.

## Warrant Liabilities

The Company accounts for warrants as liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480 and ASC 815. Warrants recorded as liabilities are recorded at their fair value, within Warrant Liabilities on the Consolidated Balance Sheets and are remeasured on each reporting date with changes recorded in Change in fair value of warrant liabilities on the Company’s Consolidated Statements of Operations.



## Fair Value Measurements

The Company applies fair value accounting for selected financial assets and liabilities measured on a recurring and nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. The accounting guidance ASC Topic 820 Fair Value Measurement established a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, used to determine the fair value of its financial instruments. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Level 1 – inputs include quoted market prices in an active market for identical assets or liabilities.

Level 2 – inputs are market data, other than Level 1, that are observable either directly or indirectly. Level 2 inputs include quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data.

Level 3 – inputs are unobservable and corroborated by little or no market data.

## Research and Development

Research and development expenditures of approximately $38,592, $17,102 and $9,594 in 2022, 2021 and 2020, respectively, were charged to expense as incurred.

## Income Taxes

The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the Consolidated Financial Statements or tax returns. Deferred tax liabilities and assets are determined based on the differences between the Consolidated Financial Statements and tax basis of assets and liabilities using the enacted tax rates in effect for the year in which the differences are expected to reverse. The measurement of deferred tax assets is reduced, if necessary, by the amount of any uncertain tax positions or tax benefits that are not expected to be realized based on available evidence. The Company records deferred tax assets and associated valuation allowances, when appropriate, to reflect amounts more likely than not to be realized based upon Company analysis. The Company’s temporary differences result primarily from capitalization of certain qualifying research and development expenses, accruals and reserves, depreciation of property and equipment, stock compensation expense, capitalization of operating or financing leases, and net operating loss carryovers.

The Company accounts for any uncertainty in income taxes by recognizing the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The Company measures the tax benefits recognized in the Consolidated Financial Statements from such a position based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution. Interest and penalties associated with tax positions are recorded in the period assessed as General and administrative on the Consolidated Statement of Operations. No interest or penalties have been assessed during the years ended December 31, 2022, 2021 and 2020.

## Net Earnings (Loss) per Share of Common Stock

Basic net earnings (loss) per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the potentially dilutive impact of stock options and warrants. The Company reported a net loss in 2022 and 2020. As such all potentially dilutive securities including options and warrants, are antidilutive and accordingly, basic net loss per share equals diluted loss per share. As the Company reported net income in 2021, diluted earnings per share reflected any dilutive effect of stock options and warrants.



## Mezzanine Equity

In accordance with ASC 480, Legacy Solid Power’s Series A-1 Preferred Stock and Series B Preferred Stock (collectively, “Preferred Stock”) prior to the Business Combination were classified as mezzanine equity as the Preferred Stock included redemption features that were not solely within control of Legacy Solid Power.

Immediately prior to the consummation of the Business Combination, 14,069,187 shares of Legacy Solid Power Series A-1 Preferred Stock and 8,777,812 shares of Legacy Solid Power Series B Preferred Stock, which represented all of the then-outstanding shares of Preferred Stock, converted to Legacy Solid Power common stock on a one-to-one basis. At the Closing (as defined below), all shares of Legacy Solid Power common stock were exchanged for shares of Solid Power Common Stock based on the Exchange Ratio.

## Recent Accounting Pronouncements

## Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), followed by other related ASUs that provided targeted improvements and additional practical expedient options. On January 1, 2022, the Company adopted the standards under Topic 842 using the modified retrospective method and elected a number of the practical expedients in its implementation of Topic 842. The key change that affected the Company relates to accounting for operating leases for which it is the lessee that were historically off-balance sheet. The impact of adopting the standards resulted in the recognition of a right-of-use asset of $7,853 and lease liability of $8,246 on the Company’s condensed consolidated balance sheet on January 1, 2022, exclusive of previously recognized lease balances. The implementation of Topic 842 did not have a material effect on the Company’s condensed consolidated statement of operations or condensed consolidated statement of cash flows for the year ended December 31, 2022.

## Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. ASU 2016-13 also provides updated guidance regarding the impairment of available-for-sale debt securities and includes additional disclosure requirements. The Company adopted this guidance as of January 1, 2022.

The Company regularly reviews its available-for-sale marketable securities and evaluates the current expected credit losses by considering factors such as any changes in credit ratings, historical experience, market data, issuer-specific factors, and current economic conditions. Based on this analysis, an allowance for credit losses is recorded as a reduction to the carrying value of the asset. To date, management has not recorded an allowance for credit losses.

The Company reviews its receivable aging on an individual customer level, considering collectability of cash flows based on the risk of past events, current conditions, and forward-looking information. The Company establishes allowances for bad debts equal to the estimable portions of accounts receivable for which failure to collect is expected to occur. Allowances for doubtful accounts are recorded as reductions to the carrying values of the related receivables. To date, the Company has not recorded an allowance for doubtful accounts.

## Income taxes

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which aims to reduce complexity in accounting standards by improving certain areas of GAAP without compromising information provided to users of financial statements. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. For all other entities, the standard is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance beginning January 1, 2022 with no financial statement impact at adoption.



## Note 3 – Business Combination

Legacy Solid Power was deemed the accounting acquirer in the Business Combination based on the analysis of the criteria outlined in ASC 805. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Solid Power issuing stock for the net assets of DCRC, accompanied by a recapitalization. The net assets of DCRC are stated at historical cost, with no goodwill or other intangible assets recorded.

Because Legacy Solid Power was deemed the accounting acquirer, the historical Consolidated Financial Statements of Legacy Solid Power became the historical Consolidated Financial Statements of the combined company. As a result, the Consolidated Financial Statements included in this report reflect (i) the historical operating results of Legacy Solid Power prior to the Business Combination; (ii) the combined results of the Company and Legacy Solid Power following the closing of the Business Combination (“Closing”); (iii) the assets and liabilities of Legacy Solid Power at their historical cost; and (iv) the Company’s equity structure for all periods presented as discussed below.

In accordance with guidance applicable to the Business Combination, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company’s Common Stock, $0.0001 par value per share issued to Legacy Solid Power’s stockholders in connection with the Business Combination. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Solid Power redeemable convertible preferred stock and common stock prior to the Business Combination have been retroactively restated to reflect the Exchange Ratio. Activity within the Consolidated Statements of Stockholders’ Equity for the issuances and repurchases of Legacy Solid Power’s redeemable convertible preferred stock were also retroactively converted to Legacy Solid Power common stock.

In connection with the Closing, and subject to the terms and conditions of the Business Combination Agreement, each outstanding share of Legacy Solid Power’s common stock (including shares of Legacy Solid Power common stock issued upon the conversion of each share of Legacy Solid Power’s Preferred Stock immediately prior to the Closing) was canceled and converted into the right to receive the number of shares of the Company’s Common Stock (as defined below) based on an Exchange Ratio equal to approximately 3.182 (the “Exchange Ratio”), and each outstanding Legacy Solid Power option issued under Legacy Solid Power’s 2014 Equity Incentive Plan (the “2014 Plan”) was converted into a Company option based on the Exchange Ratio applicable to shares of Legacy Solid Power common stock, each in accordance with the terms of the Business Combination Agreement. At the Closing, the Company issued an aggregate of 104,518,159 shares of Common Stock to the equity-holders of Legacy Solid Power and the Legacy Solid Power option-holders’ held options in the Company to receive an aggregate 34,407,949 shares of Common Stock, subject to payment of the applicable exercise price and, in certain circumstances, vesting obligations.

Furthermore, in connection with the Business Combination, (i) all shares of DCRC’s Class A common stock prior to the Business Combination were re-designated as “Common Stock, par value $0.0001 per share” of the Company (“Common Stock”) and (ii) all 40,000 shares of DCRC’s Class B common stock were converted, on a one-for-one basis, into an equivalent number of shares of the Company’s Common Stock. On the Closing Date, a number of purchasers, purchased from DCRC an aggregate of 19,500,000 shares of the Company’s Common Stock, for a purchase price of $10.00 per share and an aggregate purchase price of $195,000 (the “PIPE Financing”), pursuant to separate subscription agreements (each, a “Subscription Agreement”) entered into on June 15, 2021 or October 27, 2021.

Prior to the Closing, DCRC had $1,500 outstanding under working capital loans from Decarbonization Plus Acquisition Sponsor III LLC (the “Sponsor”), which, in connection with the Closing, the Sponsor elected to convert into warrants to purchase 1,000,000 shares of Common Stock at a price of $1.50 per share, which are included in the 7,666,667 Private Placement Warrants (as defined below).

Pursuant to the Business Combination Agreement, the Merger was accounted for as a Reverse Recapitalization in accordance with GAAP. Under this method of accounting, DCRC was treated as the “acquired” company and Legacy Solid Power is treated as the acquirer for financial reporting purposes.

The following table reconciles the elements of the Business Combination to the Consolidated Statements of Cash Flows and the Consolidated Statements of Stockholders’ Equity for the year ended December 31, 2021:



<table><tr><td></td><td>Recapitalization</td></tr><tr><td>Cash - DCRC trust and cash, net of redemptions</td><td>$ 347,914</td></tr><tr><td>Cash - PIPE Financing</td><td>195,000</td></tr><tr><td>Cash - Sponsor Funds</td><td>264</td></tr><tr><td>Non-cash net assets acquired from DCRC</td><td>(100,697)</td></tr><tr><td>Less: transaction costs and advisory fees for Legacy Solid Power allocated to equity</td><td>(5,991)</td></tr><tr><td>Less: transaction costs and advisory fees for DCRC</td><td>(41,897)</td></tr><tr><td>Net Business Combination</td><td>$ 394,593</td></tr><tr><td>Add: non-cash net assets acquired from DCRC</td><td>100,697</td></tr><tr><td>Add: accrued transaction costs and advisory fees</td><td>80</td></tr><tr><td>Net cash contributions from Business Combination</td><td>$ 495,370</td></tr></table>

Interest expense on long-term debt for the years ended December 31, 2022, 2021 and 2020 was $6, $131 and $196, respectively.



## Note 7 – Convertible Notes Payable

## 2020 Convertible Promissory Notes

On December 10, 2020 and December 18, 2020, the Company issued unsecured convertible promissory notes to investors in the total principal amount of $5,125, and on February 4, 2021, and March 1, 2021, the Company issued additional unsecured convertible promissory notes to investors in the total principal amount of $4,875, as part of a single financing (collectively, the "2020 Notes"). The 2020 Notes accrued interest at eight percent per annum. The 2020 Notes were converted into 1,007,965 shares of Legacy Solid Power Series B Preferred Stock on May 5, 2021, in conjunction with the closing of the Legacy Solid Power Series B Preferred Stock ("Series B Financing"). The outstanding balance on the 2020 Notes, including accrued interest, was $10,228 when the 2020 Notes were converted to Legacy Solid Power Series B Preferred Stock. Interest expense for 2021 was $210 for the 2020 Notes. The principal of the 2020 Notes was included in Additional paid-in capital and the fair value of the embedded derivative was recorded as a liability on the Legacy Solid Power's Consolidated Balance Sheet. The fair value of the embedded derivative was $5,497. This balance was transferred, along with the accrued interest, to mezzanine equity upon conversion of the 2020 Notes to Series B Preferred Stock in conjunction with the Series B Financing.

## 2020 Convertible Promissory Notes Embedded Derivative

The 2020 Notes contained the following embedded derivatives: (i) a share settled redemption upon Qualified Financing; (ii) share settled redemption upon De-SPAC; and; (iii) share settled redemption at maturity.

Embedded derivatives are separated from the host contract and carried at fair value when: (a) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract; and (b) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument. The Company has concluded that certain embedded derivatives within the 2020 Notes meet these criteria and, as such, must be valued separate and apart from the 2020 convertible promissory notes as one embedded derivative and recorded at fair value each reporting period.

## 2019 Convertible Promissory Notes

On December 4, 2019, the Company issued an unsecured convertible promissory note to an investor in the principal amount of $3,000 (the “2019 Note,” and together with the 2020 Notes, the “Convertible Promissory Notes”). The 2019 Note accrued interest at 5 percent per annum. The 2019 Note converted into 254,899 shares of Legacy Solid Power Series B Preferred Stock, in conjunction with the Series B Financing. Upon this conversion, the 2019 Note converted to Series B Preferred Stock at a 30 percent discount. Interest expense incurred for the year ended December 31, 2020 was $150. Prior to conversion, interest expense incurred for the year ended December 31, 2020 was $53.

For all debt instruments, including any for which the Company has elected fair value accounting, the Company classifies interest that has been accrued during each period as Interest expense on the Consolidated Statements of Operations.

## Note 8 – Fair Value Measurements

The Company considers all highly liquid instruments with original maturities of less than 90 days to be cash equivalents. As of December 31, 2022, there were no long-term marketable securities.

The carrying amounts of certain financial instruments, such as cash equivalents, short-term investments, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities.

The fair value of debt instruments for which the Company has not elected fair value accounting is based on the present value of expected future cash flows and assumptions about the then-current market interest rates as of the reporting period and the creditworthiness of the Company. The book values of the Company’s long-term debt approximate fair value because interest rates charged are similar to other financial instruments with similar terms and maturities and the rates vary in accordance with a market index. Most of the Company’s debt is carried on the Consolidated Balance Sheets on a historical cost basis net of unamortized discounts and premiums because the Company has not elected the fair value option of accounting. Changes to the inputs used in these valuation models can have a significant impact on the estimated fair value of the Convertible Promissory Notes and the Company’s embedded derivatives.



## Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

As discussed in Note 7, all Convertible Promissory Notes were converted to Legacy Solid Power Series B Preferred Stock in May 2021. As of December 31, 2022 and 2021, the Company’s financial liabilities measured and recorded at fair value on a recurring basis were classified within the fair value hierarchy as follows:

<table><tr><td rowspan="2"></td><td colspan="4">December 31, 2022</td></tr><tr><td>Level 1</td><td>Level 2</td><td>Level 3</td><td>Total</td></tr><tr><td>Assets</td><td></td><td></td><td></td><td></td></tr><tr><td>Commercial Paper</td><td>$ 165,179</td><td>$ —</td><td>$ —</td><td>$ 165,179</td></tr><tr><td>Corporate Bonds</td><td>$ 227,957</td><td>$ —</td><td>$ —</td><td>$ 227,957</td></tr><tr><td>Government Bonds</td><td>$ 42,865</td><td>$ —</td><td>$ —</td><td>$ 42,865</td></tr><tr><td>U.S. Treasuries</td><td>9,930</td><td>—</td><td>—</td><td>9,930</td></tr><tr><td>Liabilities</td><td></td><td></td><td></td><td></td></tr><tr><td>Public Warrants</td><td>$ 4,900</td><td>$ —</td><td>$ —</td><td>$ 4,900</td></tr><tr><td>Private Warrants</td><td>$ —</td><td>$ 4,217</td><td>$ —</td><td>$ 4,217</td></tr><tr><td></td><td colspan="4">December 31, 2021</td></tr><tr><td></td><td>Level 1</td><td>Level 2</td><td>Level 3</td><td>Total</td></tr><tr><td>Assets</td><td></td><td></td><td></td><td></td></tr><tr><td>Commercial Paper</td><td>$ 33,275</td><td>$ —</td><td>$ —</td><td>$ 33,275</td></tr><tr><td>Corporate Bonds</td><td>$ 39,593</td><td>$ —</td><td>$ —</td><td>$ 39,593</td></tr><tr><td>Government Bonds</td><td>$ 3,017</td><td>$ —</td><td>$ —</td><td>$ 3,017</td></tr><tr><td>Liabilities</td><td></td><td></td><td></td><td></td></tr><tr><td>Public Warrants</td><td>$ 26,483</td><td>$ —</td><td>$ —</td><td>$ 26,483</td></tr><tr><td>Private Warrants</td><td>$ —</td><td>$ 23,537</td><td>$ —</td><td>$ 23,537</td></tr></table>

The change in fair value of the Company’s marketable securities is included in Other Comprehensive loss. There were no transfers in and out of Level 3 fair value hierarchy during the years ended December 31, 2022 and 2021. For the year ended December 31, 2022 the Company purchased $561,565 of marketable securities.

## Fair Value Methodology

## 2020 Notes Embedded Derivative

The fair value of the 2020 Notes was estimated using the present value of probability weighted scenario analysis, considering the as-converted value and the downside protection. The embedded derivative is valued using a “with-and-without method,” where the value of the 2020 Notes, including the embedded derivative, is defined as the “with”, and the value of the 2020 Notes, excluding the embedded derivative, is defined as the “without.” This method estimates the value of the embedded derivative by comparing the difference in the values between the 2020 Notes with the embedded derivative and the value of the 2020 Notes, without the embedded derivative. The probability weighted scenario analysis requires the following inputs: (i) probability of qualified financing, maturity, and other contingent scenarios; (ii) equity value; (iii) conversion price; (iv) maturity date; (v) risk-free interest rate; and (vi) estimated volatility. The changes during the twelve months ended December 31, 2021 in the fair values of the embedded derivatives are primarily related to the change in the value of the conversion features and are reflected in the Consolidated Statements of Operations as “Loss from change in fair value of embedded derivative liability.” The embedded derivative liability was settled as of December 31, 2021.



## Fair Value of Debt - 2019 Note

The 2019 Note was converted to Legacy Solid Power Series B Preferred Stock in May 2021. At December 31, 2020, the contractual outstanding principal of the 2019 Note was $3,000, and the fair value was $3,612. The fair value was estimated using the present value of probability weighted scenario analysis, considering the as-converted value and the downside protection. The probability weighted scenario analysis requires the following inputs: (i) probability of qualified financing, maturity and other contingent scenarios; (ii) equity value; (iii) conversion price; (iv) maturity date; (v) risk-free interest rate; and (vi) estimated volatility.

## Fair Value of Common Stock Warrant Liabilities

The fair value of the Private Placement Warrant Liabilities have been estimated using a Black-Scholes model as of the Closing Date and subsequently as of the December 31, 2022 and 2021 Consolidated Balance Sheet dates. The fair value of the Public Warrants (defined below) has been measured based on the quoted price of such warrants on the Nasdaq Stock Market, a Level 1 input. The estimated fair value of the Private Placement Warrants (defined below) is determined using Level 2 inputs. Inherent in a Black-Scholes model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. Material increases (or decreases) in any of those inputs may result in a significantly higher (or lower) fair value measurement. The Company estimates the volatility of its Private Placement Warrants based on implied volatility from the Company’s Public Warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend yield is based on the historical rate, which the Company anticipates remaining at zero.

The following table provides quantitative information regarding Level 2 inputs used in the recurring valuation of the Private Placement Warrants as of their measurement dates:

<table><tr><td></td><td>December 31, 2022</td><td>December 31, 2021</td></tr><tr><td>Exercise Price</td><td>$ 11.50</td><td>$ 11.50</td></tr><tr><td>Stock Price</td><td>$ 2.54</td><td>$ 8.74</td></tr><tr><td>Volatility</td><td>71.3 %</td><td>48.9 %</td></tr><tr><td>Term</td><td>3.94</td><td>4.94</td></tr><tr><td>Risk-free rate</td><td>4.03 %</td><td>1.24 %</td></tr></table>

The following table provides a reconciliation of the Public Warrants measured at fair value using Level 1 directly observable inputs and Private Placement Warrants measured at fair value using Level 2 directly or indirectly observable inputs:

<table><tr><td></td><td>Public Warrants Level 1 Fair Value</td><td>Private Warrants Level 2 Fair Value</td></tr><tr><td>December 31, 2021</td><td>$ 2.27</td><td>$ 3.07</td></tr><tr><td>Change in fair value</td><td>$ (1.85)</td><td>$ (2.52)</td></tr><tr><td>December 31, 2022</td><td>$ 0.42</td><td>$ 0.55</td></tr></table>

The following tables provide a reconciliation of the change in fair value for the Public and Private Placement Warrants for the years ended December 31, 2022 and 2021.

## Note 9 – Common Stock Warrant Liabilities

As of December 31, 2022 and December 31, 2021, there were 11,666,636 publicly traded warrants (“Public Warrants”) and 7,666,667 private placement warrants (“Private Placement Warrants,” and together with the Public Warrants, “Warrants”) outstanding. Each whole Warrant entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to customary adjustments. Only whole Warrants are exercisable. The Warrants became exercisable on January 7, 2022 and will expire on December 8, 2026.

## Redemption of Public Warrants when the price per share of Common Stock equals or exceeds $18.00.

The Company may redeem all of the outstanding Public Warrants:

• in whole and not in part;

• upon at least 30 days’ prior written notice;

• at a price of $0.01 per Public Warrant; and

- if the last sale price of the Company’s Common Stock equals or exceeds $18.00 per share, subject to customary adjustments, for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which notice of the redemption is given.

## Redemption of Public Warrants when the price per share of Common Stock equals or exceeds $10.00.

The Company may redeem all of the outstanding Public Warrants:

• in whole and not in part;

• upon at least 30 days’ prior written notice;

- at a price of $0.10 per Public Warrant, provided that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive a number of shares of Common Stock determined in part by the redemption date and the “fair market value” of the Common Stock; and

- if the last sale price of the Company’s Common Stock equals or exceeds $10.00 per share, subject to customary adjustments, on the trading day prior to the date on which notice of redemption is given.

The “fair market value” of the Company’s Common Stock means the average reported last sale price of the Company’s Common Stock for the ten trading days immediately following the date on which the notice of redemption is sent to the holders of Warrants. The Company classifies the outstanding Warrants as Warrant Liabilities on the condensed consolidated balance sheets in accordance with the guidance contained in ASC 815.

None of the Private Placement Warrants are redeemable by the Company so long as they are held by the initial purchasers of the Private Placement Warrants or their permitted transferees.

The Warrant Liabilities were initially measured at fair value upon Closing of the Business Combination for $101,253 and subsequently re-measured on December 31, 2021 and December 31, 2022 for $50,020 and $9,117, respectively. The Public Warrants were allocated a portion of the proceeds from the issuance of the units of common stock and one-third warrants in DCRC’s initial public offering equal to their fair value. The Company recognized a gain in connection with changes in the fair value of warrant liabilities of $40,903 and $51,233 as of December 31, 2022 and 2021, respectively.



## Note 10 – Mezzanine Equity

In accordance with ASC 480, Legacy Solid Power’s Preferred Stock prior to the Business Combination was classified as mezzanine equity. Immediately prior to the Closing, Legacy Solid Power had 14,069,187 shares of Series A-1 Preferred Stock outstanding and 8,777,812 shares of Series B Preferred Stock outstanding. Legacy Solid Power issued the Series B Preferred Stock in May 2021 in exchange for 135,579 of cash and the conversion of the 2019 Note and the 2020 Notes.

Prior to the Business Combination, the Preferred Stock had a redemption feature, at the option of the holders of a majority of the outstanding Preferred Stock, any time after April 30, 2031. The Preferred Stock was redeemable for the greater of its original issue price, plus all declared but unpaid dividends thereon, or fair value. Since the Preferred Stock had redemption provisions that were not solely within control of Legacy Solid Power, the Preferred Stock was classified prior to the Business Combination as mezzanine equity on Legacy Solid Power’s balance sheets.

Immediately prior to the Business Combination, 14,069,187 shares of Series A-1 Preferred Stock and 8,777,812 shares of Series B Preferred Stock were converted to the equivalent number of shares of Legacy Solid Power common stock. At the Closing, those shares of Legacy Solid Power common stock were exchanged for Common Stock in accordance with the Exchange Ratio.

## Note 11 – Stockholders’ Equity

## Common Stock

Stock options exercised for Common Stock are summarized in the table below:

<table><tr><td rowspan="2"></td><td colspan="3">December 31,</td></tr><tr><td>2022</td><td>2021</td><td>2020</td></tr><tr><td>Stock options exercised</td><td>8,428,524</td><td>1,160,930</td><td>1,097,370</td></tr></table>

Cash received from options exercised under the Legacy Solid Power, Inc. 2014 Equity Incentive Plan (the “2014 Plan”) for the years ended December 31, 2022, 2021 and 2020 was $818, $106 and $24, respectively.

During the years ended December 31, 2022, 2021 and 2020, restricted stock units (“RSUs”) vested for 29,108, 0, and 0 shares of Common Stock, respectively.

## Legacy Solid Power Warrants

During 2015, Legacy Solid Power issued warrants to a third party to purchase 276,000 shares of Legacy Solid Power common stock at an exercise price of $0.00001088 per share, in conjunction with a licensing agreement. Management determined that equity classification is appropriate for these warrants. Legacy Solid Power recognized expense totaling $18 on the date of the grant that has been included as a component of Additional Paid In Capital within the consolidated statement of stockholders' equity. During 2020, Legacy Solid Power issued additional warrants to purchase 45,730 shares of common stock at an exercise price of $0.53 per share. Legacy Solid Power recognized expense totaling $16 on the date of the grant.

In May 2021, Legacy Solid Power issued warrants to purchase 1,755,557 shares of Legacy Solid Power common stock at an exercise price of $0.01 per share, in connection with the Series B Financing. These warrants were detachable from the Legacy Solid Power Series B Preferred Stock and in all cases would physically settle or net share settle. Therefore, Legacy Solid Power determined that these warrants represented equity in Legacy Solid Power. Prior to the Closing, all Legacy Solid Power warrants were either exercised for cash or net exercised and the holders thereof received shares of Legacy Solid Power common stock.



## Note 12 – Stock Based Compensation

## 2014 Equity Incentive Plan and 2021 Equity Incentive Plan

Options granted under the 2014 Plan generally had a ten-year term and vest as to 1/4th of these shares after one year after the initial date of service of a service provider and with the balance of the shares vesting in a series of 36 successive equal monthly installments following the first vesting date. Option awards under the 2014 Plan were generally granted with an exercise price equal to the fair market value of Legacy Solid Power’s common stock at the date of grant. Certain option awards issued under the 2014 Plan provide for accelerated vesting if there is a change in control (as defined in the plan agreements).

On December 8, 2021 and in connection with the Closing, the Company adopted the Solid Power, Inc. 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan originated with 18,900,000 shares of Common Stock available for issuance. Beginning on January 1, 2022, the number of shares of common stock available for issuance under the 2021 Plan shall increase each year by an amount equal to the lesser of (i) 18,900,000 shares of Common Stock (ii) five percent of the total number of shares of common stock outstanding on the last day of the immediately preceding fiscal year; or (iii) a number of shares of common stock determined by the administrator no later than the last day of the immediately preceding fiscal year. Awards may be issued in the form of stock options, stock appreciation rights, restricted stock, and restricted stock units. The Company believes that such awards better align the interests of its employees with those of its stockholders.

Options granted under the 2021 Plan generally have a ten-year term and vest as to 1/4th of these shares per year beginning one year after the initial date of service of a service provider. Option awards under the 2021 Plan were generally granted with an exercise price equal to the fair market value of the Company’s common stock at the date of grant. Certain option awards issued under the 2021 Plan provide for accelerated vesting if there is a change in control (as defined in the plan agreements).

Effective April 1, 2022, the Company began granting RSUs in accordance with the terms of the 2021 Plan. The grant date fair value of RSUs awarded are determined based on the Company’s closing common share price on the NASDAQ on the trading day preceding the grant date. RSU awards for employees generally vest 25% per year commencing on the first anniversary of the grant date. RSU awards upon initial service as a director vest in 12 equal quarterly installments. For initial service grants, vested RSUs are settled in common stock upon the earlier of the director no longer serving on the board of directors or the date the RSU has fully vested. Annual RSU awards to directors generally fully vest on the one-year anniversary of the grant date. Upon vesting, granted RSUs entitle the grantee to receive one share of common stock of the Company at no additional cost. Holders of unvested RSUs do not have voting or dividend rights.

At December 31, 2022 and 2021 the Company had 24,766,176 and 34,407,949 shares of common stock underlying stock options outstanding under the 2014 Plan respectively. Upon the Closing, the 2014 Plan was terminated and no additional grants were made under the 2014 Plan.

As of December 31, 2022, the 2021 Plan permitted the Company to grant up to 24,466,527 shares of common stock to its employees, directors, and consultants, as designated by the board of directors.

## Compensation Expense for Stock Based Compensation

The fair value of stock options and RSUs issued to employees and directors is recognized as compensation expense over the period of service that generally coincides with the vesting period of the award. When calculating the amount of annual compensation expense, the Company has elected not to estimate forfeitures and instead accounts for forfeitures as they occur.



For the years ended December 31, 2022, 2021 and 2020 the Company recognized compensation costs totaling:

<table><tr><td rowspan="2"></td><td colspan="3">December 31,</td></tr><tr><td>2022</td><td>2021</td><td>2020</td></tr><tr><td>Equity-based compensation costs related to RSUs</td><td>$ 1,567</td><td>$ —</td><td>$ —</td></tr><tr><td>Equity-based compensation costs related to stock options</td><td>7,076</td><td>2,714</td><td>182</td></tr><tr><td>Equity-based compensation costs related to ESPP</td><td>29</td><td>—</td><td>—</td></tr><tr><td>Total equity-based compensation costs</td><td>$ 8,672</td><td>$ 2,714</td><td>$ 182</td></tr><tr><td>Future compensation costs related to unvested options</td><td>$ 19,322</td><td>$ 23,307</td><td>$ 593</td></tr></table>

The fair value of stock options and other equity-based compensation issued to employees is recognized as compensation expense over the period of service that generally coincides with the vesting period of the award. The Company allocated compensation ratably across Operating Expenses within the following financial statement lines:

<table><tr><td rowspan="2"></td><td colspan="3">December 31,</td></tr><tr><td>2022</td><td>2021</td><td>2020</td></tr><tr><td>Direct Costs</td><td>$ 1,580</td><td>$ 332</td><td>$ 22</td></tr><tr><td>Research and Development</td><td>4,474</td><td>1,698</td><td>115</td></tr><tr><td>Sales and Marketing</td><td>493</td><td>308</td><td>23</td></tr><tr><td>General and Administrative</td><td>2,125</td><td>376</td><td>22</td></tr><tr><td>Total equity-based compensation cost</td><td>$ 8,672</td><td>$ 2,714</td><td>$ 182</td></tr></table>

## Stock Options

The fair value for purposes of determining the compensation cost of each option award is estimated on the date of grant using a Black-Scholes option valuation model that uses the weighted-average assumptions noted in the following table. Expected volatilities are based on historical volatility of comparable companies. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The fair value of each option grant during the years ended December 31, 2022, 2021 and 2020 was estimated on the grant date using the Black-Scholes option pricing model with the following weighted-average assumptions used:

<table><tr><td></td><td colspan="2">2022</td><td colspan="2">2021</td><td colspan="2">2020</td></tr><tr><td>Approximate risk-free rate</td><td colspan="2">2.84 %</td><td colspan="2">1.04 %</td><td colspan="2">1.29 %</td></tr><tr><td>Volatility</td><td colspan="2">44.69 %</td><td colspan="2">41.45 %</td><td colspan="2">43.92 %</td></tr><tr><td>Average expected life (years)</td><td colspan="2">6 years</td><td colspan="2">6 years</td><td colspan="2">6 years</td></tr><tr><td>Dividend yield</td><td colspan="2">0 %</td><td colspan="2">0 %</td><td colspan="2">0 %</td></tr><tr><td>Weighted-average grant date fair value</td><td>$</td><td>7.26</td><td>$</td><td>5.10</td><td>$</td><td>0.84</td></tr><tr><td>Estimated fair value of total options granted</td><td>$</td><td>5,659</td><td>$</td><td>25,353</td><td>$</td><td>246</td></tr></table>

When calculating the amount of annual compensation expense, the Company has elected not to estimate forfeitures and instead accounts for forfeitures as they occur.



A summary of option activity under the 2014 Plan and 2021 Plan for the years ended December 31, 2022, 2021, and 2020 is presented below:

The aggregate intrinsic value of exercisable options at December 31, 2022 was $35,058. The aggregate intrinsic value of exercised options at December 31, 2022 was $63,287.

## Restricted Stock Units

The following table summarizes non-vested RSUs at December 31, 2022 and the changes for the period ended December 31, 2022:

<table><tr><td></td><td>Number of Shares</td><td>Weighted-average Grant Date Fair Value</td></tr><tr><td>Balance at January 1, 2022</td><td>—</td><td></td></tr><tr><td>Granted</td><td>1,292,429</td><td>$ 7.11</td></tr><tr><td>Vested</td><td>(29,108)</td><td>$ 7.26</td></tr><tr><td>Forfeited</td><td>(205,341)</td><td>$ 7.33</td></tr><tr><td>Outstanding at December 31, 2022</td><td>1,057,980</td><td>$ 7.06</td></tr></table>

## 2021 Employee Stock Purchase Plan

The 2021 Employee Stock Purchase Plan (“2021 ESPP”) originated with 3,778,000 shares of Common Stock available for issuance. As of December 31, 2021, 3,778,000 shares remained available for issuance. Beginning on January 1, 2022, the number of shares of Common Stock available for issuance under the 2021 ESPP shall increase by an amount equal to the lesser of (i) 3,778,000 shares of Common Stock (ii) one percent (1%) of the total number of shares of Common Stock outstanding on the last day of the immediately preceding fiscal year or (iii) a number of shares of Common Stock determined by the Administrator no later than the last day of the immediately preceding fiscal year. As of December 31, 2022 5,463,579 shares remained available for issuance. As of December 31, 2022 the 2021 ESPP permitted the Company to issue up to 5,463,579 shares of common stock.

The Company recorded $29 of expense related to the 2021 ESPP in the year ended December 31, 2022. No shares have been purchased under the ESPP as of December 31, 2022. As of December 31, 2022, there was $58 of unrecognized stock-based compensation expense related to the ESPP that is expected to be recognized by the end of second quarter of 2023.

The 2021 ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. Substantially all employees are eligible to participate and, through payroll deductions, can purchase shares on dates determined by the administrator. However, with respect to the Section 423 Component, an employee may not be granted rights to purchase stock under the ESPP if the employee, immediately after the grant, would own (directly or through attribution) stock possessing 5% or more of the total combined voting power or value of all classes of the Company’s Common Stock. The purchase price per share sold pursuant to the 2021 ESPP will be the lower of (i) 85% of the fair market value of Common Stock on the enrollment or (ii) 85% of the fair market value on the exercise date. Each offering period will span up to six months. Purchases may be up to 15% of qualified compensation, with an annual limit of $25,000.

## Note 13 – Earnings (Loss) Per Share

The table below reconciles basic weighted average common shares outstanding to diluted weighted average shares outstanding for December 31, 2022, 2021 and 2020.

Basic earnings per share is based on the weighted average number of common shares outstanding for the period. Basic earnings per share represents net earnings or loss attributable to Common Stock divided by the basic weighted average number of common shares outstanding during the period.

Diluted earnings per share also includes the dilutive effect of additional potential common shares issuable from stock-based awards and are determined using the treasury stock method. Diluted earnings per share represents net earnings divided by diluted weighted average number of common shares, which includes the average dilutive effect of all potentially dilutive securities that are outstanding during the period.

The unvested stock awards, warrants, and options are included in the number of shares outstanding for diluted earnings per share calculations, unless a net loss is reported, in which situation unvested stock awards, warrants, and options are excluded from the number of shares outstanding for diluted earnings per share calculations.

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2022</td><td>2021</td><td>2020</td><td></td></tr><tr><td>Net income (loss) attributable to common stockholders</td><td>$ (9,555)</td><td>$ 12,656</td><td>$ (14,375)</td><td></td></tr><tr><td>Weighted average shares outstanding - basic</td><td>174,374,386</td><td>95,477,472</td><td>69,228,444</td><td></td></tr><tr><td>Weighted average shares outstanding - diluted</td><td>174,374,386</td><td>114,910,129</td><td>69,228,444</td><td></td></tr><tr><td>Basic earnings (loss) per share</td><td>$ (0.05)</td><td>$ 0.13</td><td>$ (0.21)</td><td></td></tr><tr><td>Diluted earnings (loss) per share</td><td>$ (0.05)</td><td>$ 0.11</td><td>$ (0.21)</td><td></td></tr></table>



Due to the net loss to common stockholders in 2022 and 2020 presented above, diluted loss per share was computed without consideration of potentially dilutive instruments as their inclusion would have been anti-dilutive. Warrants outstanding in 2022 and 2021 were not included in the computation of diluted earnings per share because the warrant’s exercise price for the period was greater than the average market price of the common shares. As of December 31, 2022, 2021 and 2020, potentially dilutive securities excluded from the diluted earnings (loss) per share calculation are as follows (in shares):

<table><tr><td></td><td>2022</td><td>2021</td><td>2020</td></tr><tr><td>Common Stock Warrants</td><td>19,333,303</td><td>19,333,303</td><td>1,023,745</td></tr><tr><td>2014 &amp; 2021 Equity Incentive Plan - Stock Options</td><td>26,328,279</td><td>—</td><td>23,476,182</td></tr><tr><td>2021 Equity Incentive Plan - Restricted Stock Units</td><td>710,385</td><td>—</td><td>—</td></tr><tr><td>2021 Employee Stock Purchase Plan</td><td>26,589</td><td>—</td><td>—</td></tr><tr><td>Contingently Issuable Common Stock</td><td>5,339</td><td>—</td><td>—</td></tr><tr><td>Total potentially dilutive securities</td><td>46,403,895</td><td>19,333,303</td><td>24,499,927</td></tr></table>

## Note 14 – Leases

The Company leases its two facilities and certain equipment. Fixed rent generally escalates each year, and the Company is responsible for a portion of the landlords' operating expenses such as property tax, insurance and common area maintenance.

The Company’s facility in Louisville, Colorado is under a noncancelable operating lease with a maturity date in September 2029. In 2022, the Company amended the lease to incorporate a prior subleased space into the base lease and extend the term of the lease. The Company has the right to renew this lease for an additional five-year period.

On September 1, 2021, the Company entered into an industrial operating lease agreement for its facility in Thornton, Colorado, with the initial term through March 31, 2029. Under this operating lease, the Company has one option to renew for five years, which has been included in the calculation of lease liabilities and right-of-use assets at the adoption date of the lease accounting standard on January 1, 2022, as the exercise of the option was reasonably certain. As the renewal rent has not been negotiated, the Company used an estimated rent rate which approximated the fair market rent at adoption of ASC 842 on January 1, 2022 for the extension period.

The Company has certain equipment leases classified as finance leases as of December 31, 2022.

The Company’s leases do not have any contingent rent payments and do not contain residual value guarantees.

The components of lease expense are as follows:

<table><tr><td></td><td>December 31, 2022</td><td>December 31, 2021</td></tr><tr><td>Finance lease costs:</td><td></td><td></td></tr><tr><td>Amortization of right-of-use assets</td><td>$ 92</td><td>$ —</td></tr><tr><td>Interest on lease liabilities</td><td>28</td><td>—</td></tr><tr><td>Operating lease costs</td><td>850</td><td>—</td></tr><tr><td>Total lease expense</td><td>$ 970</td><td>$ —</td></tr></table>

## Note 15 – Related Party Transactions

During 2020, the Company entered into a subcontractor agreement with Roccor, LLC, which was a related party until October 30, 2020. Under the subcontractor agreement, the Company provided technical support to Roccor on a government research contract. The total value of the subcontract is $331 to the Company. The period of performance commenced during 2020 and extended to late 2021. Related party revenue from Roccor was $163 for the year ended December 31, 2020.

During 2022, the Company entered into a collaborative arrangement with BMW of North America, LLC (“BMW”). Pursuant to the terms of the agreement, the Company granted BMW a research and development-only license to certain of the Company’s intellectual property relating to solid-state battery cell manufacturing (the “R&D License”). The R&D License allows, among other things, BMW to install a solid-state prototype cell manufacturing line based upon the Company’s proprietary information. The R&D License is limited to BMW’s research and development activities and may not be used for commercial battery cell production.

The Company and BMW also agreed to negotiate a non-exclusive short-term electrolyte supply agreement for the Company to supply BMW with electrolyte material for use in BMW’s cell manufacturing, which is expected to commence in 2024 following commissioning of BMW’s solid-state prototype cell manufacturing line.



Pursuant to the agreement, prior to installation of BMW’s anticipated prototype cell manufacturing line, the Company and BMW have agreed to undertake development and manufacturing activities jointly at the Company’s facilities. Any intellectual property developed jointly by the Company and BMW at the Company’s facilities will be solely owned by the Company (“Joint Onsite Foreground IP”). To the extent intellectual property is jointly conceived but not considered Joint Onsite Foreground IP, the Company and BMW will jointly own such intellectual property. Each party will solely own intellectual property developed solely by such party. The Company and BMW will each have the right to utilize the other party’s technical improvements for research and development purposes only. Subject to certain limitations, the Company has the right to cause BMW to license BMW’s technical improvements to the Company for commercial purposes.

In consideration of the R&D License and additional development activities contemplated by the agreement BMW will pay the Company $20 million between December 2022 and June 2024, subject to the Company achieving certain milestones. For the year ended December 31, 2022, the Company has recognized $2 million of revenue from BMW and recorded $4 million of deferred revenue related to cash paid from BMW in advance of services provided.

Unrelated to the terms under the R&D License agreement the Company received $375 from BMW in exchange for initial prototype cells.

## Note 16 – Retirement Plans

The Company sponsors a 401(k) plan for all employees. The plan provides for the Company to make a discretionary matching contribution. Contributions to the plan totaled $802, $352 and $226 for the years ended December 31, 2022, 2021 and 2020, respectively.

## Note 17 – Income Taxes

The Company provides deferred U.S. federal, state, or foreign income tax benefits for all of the periods presented. The Company has also provided a valuation allowance on the net deferred tax asset because of uncertainty regarding its realizability. Realization of deferred tax assets is dependent on generating sufficient taxable income prior to the expiration of loss carryforwards.

Deferred tax assets and liabilities arise primarily from net operating loss carryforwards and temporary differences arising from the amortization of intangible assets, depreciation on property and equipment, and various accrued liabilities.

Income taxes included in the Consolidated Statements of Operations for the years ended December 31, 2022, 2021 and 2020 are detailed below:

<table><tr><td rowspan="2"></td><td colspan="4">For the Years Ended December 31,</td></tr><tr><td>2022</td><td>2021</td><td>2020</td><td></td></tr><tr><td>Deferred income tax (benefit) expense:</td><td></td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>$ (195)</td><td>$ (22)</td><td>$ 96</td><td></td></tr><tr><td>State</td><td>(32)</td><td>(3)</td><td>22</td><td></td></tr><tr><td>Total income tax (benefit) expense</td><td>$ (227)</td><td>$ (25)</td><td>$ 118</td><td></td></tr></table>



The tables below represent a reconciliation of the statutory federal income tax expense to income tax:

<table><tr><td rowspan="2"></td><td colspan="3">December 31,</td></tr><tr><td>2022</td><td>2021</td><td>2020</td></tr><tr><td>Income tax expense at the federal statutory rate</td><td>21.00 %</td><td>21.00 %</td><td>21.00 %</td></tr><tr><td>State income taxes - net of federal income tax benefits</td><td>13.07 %</td><td>(5.97)%</td><td>2.96 %</td></tr><tr><td>Permanent Differences</td><td>(3.14)%</td><td>0.25 %</td><td>1.08 %</td></tr><tr><td>Permanent Differences - Related to Convertible Debt</td><td>0.00 %</td><td>0.31 %</td><td>(5.04)%</td></tr><tr><td>Permanent Differences - Fair Value Adjustments- Warrant Liability</td><td>66.21 %</td><td>(56.44)%</td><td>0.00 %</td></tr><tr><td>Permanent Differences - Fair Value Adjustments- Marketable Securities</td><td>(5.13)%</td><td>0.00 %</td><td>0.00 %</td></tr><tr><td>Prior year provision to return</td><td>0.03 %</td><td>(0.03)%</td><td>(0.03)%</td></tr><tr><td>Net change in valuation allowance</td><td>(104.28)%</td><td>40.73 %</td><td>(20.81)%</td></tr><tr><td>Research and Development</td><td>13.65 %</td><td>0.00 %</td><td>0.00 %</td></tr><tr><td>Other</td><td>0.33 %</td><td>0.01 %</td><td>0.00 %</td></tr><tr><td>Total income tax (benefit)</td><td>1.75 %</td><td>(0.14)%</td><td>(0.84)%</td></tr></table>

For the years ended December 31, 2022, 2021 and 2020, the effective tax rate was approximately 1.75%, (0.14%) and (0.84%), respectively. Differences between the statutory rate and the Company’s effective tax rate resulted from changes in valuation allowance and permanent differences for tax purposes in the treatment of certain nondeductible expenses.

The tax effects of temporary differences that give rise to significant portions of the deferred income tax assets and liabilities are presented below:

<table><tr><td rowspan="2"></td><td colspan="3">December 31,</td></tr><tr><td>2022</td><td>2021</td><td></td></tr><tr><td>Deferred tax assets:</td><td></td><td></td><td></td></tr><tr><td>Net operating loss</td><td>$ 17,962</td><td>$ 15,591</td><td></td></tr><tr><td>R&amp;D Credit</td><td>1,908</td><td>—</td><td></td></tr><tr><td>Stock compensation</td><td>1,991</td><td>417</td><td></td></tr><tr><td>Section 174 Capitalization</td><td>5,731</td><td>—</td><td></td></tr><tr><td>ROU Lease Liability</td><td>2,459</td><td>—</td><td></td></tr><tr><td>Other</td><td>748</td><td>49</td><td></td></tr><tr><td>Total income tax expense (benefit)</td><td>30,799</td><td>16,057</td><td></td></tr><tr><td>Valuation allowance</td><td>(28,030)</td><td>(14,536)</td><td></td></tr><tr><td>Net deferred tax assets:</td><td>2,769</td><td>1,521</td><td></td></tr><tr><td>Deferred tax liabilities:</td><td></td><td></td><td></td></tr><tr><td>Intangibles (non-goodwill)</td><td>$ (1)</td><td>$ —</td><td></td></tr><tr><td>Property and equipment</td><td>(652)</td><td>(1,747)</td><td></td></tr><tr><td>ROU Asset</td><td>(2,116)</td><td>—</td><td></td></tr><tr><td>Total deferred tax liabilities</td><td>(2,769)</td><td>(1,747)</td><td></td></tr><tr><td>Total net deferred tax liability</td><td>$ —</td><td>$ (226)</td><td></td></tr></table>

The ultimate realization of deferred tax assets is dependent upon the existence, or generation, of taxable income in the periods when those temporary differences and net operating loss carryovers are deductible. Management considers the scheduled reversal of deferred tax liabilities, taxes paid in carryover years, projected future taxable income, available tax planning strategies, and other factors in making this assessment. Based on available evidence, management does not believe it is more likely than not that all of the deferred tax assets will be realized. Accordingly, the Company has established a valuation allowance equal to the net realizable deferred tax assets. The valuation allowance increased by $13,494 in 2022.



At December 31, 2022, 2021 and 2020, the Company had total domestic Federal net operating loss carryovers of approximately $73,367, $63,391 and $29,836, respectively. Federal net operating losses generated on or prior to December 31, 2017 expire in 2037. Federal net operating losses generated on or after January 1, 2018 have an indefinite carryforward and are only available to offset 80% taxable income beginning in 2021. The determination of state net operating loss carryforwards is dependent upon apportionment percentages and state laws that can change from year to year and that can thereby impact the amount of such carryforwards. The majority of the state net operating losses have an indefinite carryforward.

Accounting for uncertainty in income taxes is based on a recognition threshold and measurement attribute for the Consolidated Financial Statements recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes in its Consolidated Financial Statements only those tax positions that are more-likely-than-not to be sustained as of the adoption date, based on the technical merits of the position. Each year the Company performs a comprehensive review of its material tax positions. The Company’s policy is to recognize interest and penalties related to uncertain tax benefits in income tax expense.

As the Company had no uncertain tax benefits before the year ending December 31, 2022, there is no accrual of interest or penalties related to uncertain tax positions.

The following table summarizes the Company’s unrecognized tax benefits:

<table><tr><td>Balance, beginning of year</td><td>$</td><td>December 31, 2022</td></tr><tr><td>Gross increases related to prior period tax position</td><td></td><td>—</td></tr><tr><td>Gross increases related to current period tax position</td><td></td><td>636</td></tr><tr><td>Gross decreases related to prior period tax position</td><td></td><td>—</td></tr><tr><td>Balance, end of year</td><td></td><td>$ 636</td></tr></table>

Included in the balance of unrecognized tax benefits at December 31, 2022, are potential benefits of $636 that if recognized would affect the effective tax rate.

The 2018 through 2021 tax years remain open to examination by the Internal Revenue Service and, with few exceptions, various other state tax agencies. These taxing authorities have the authority to examine those tax years until the applicable statutes of limitations expire.

## Note 18 – Contingencies

In the normal course of business, the Company may be party to litigation from time to time. The Company maintains insurance to cover certain actions and believes that resolution of such litigation will not have a material adverse effect on the Company. DCRC, the predecessor to the Company, received a demand letter dated August 31, 2021 from counsel purporting to represent a stockholder of DCRC alleging that the proposed vote on the Authorized Share Charter Proposal (“Proposal”) for the proposed business combination with Legacy Solid Power violated Section 242(b)(2) of the Delaware General Corporation law and demanded that DCRC provide DCRC’s Class A stockholders with a separate class vote on the Proposal. DCRC subsequently provided for the Class A stockholders to have a separate class vote on the Proposal share increase. The Proposal was approved and the Business Combination closed. The counsel who issued this demand letter made a fee demand (the “Fee Demand”) for prompting the change in the Proposal. The Company accrued a liability of $500 on its Consolidated Balance Sheets as of December 31, 2021 in anticipation of settling the Fee Demand. On March 10, 2022, the Company settled the Fee Demand for an amount that is materially consistent with our accrual.

Based on cash on hand at December 31, 2022, management believes the Company has sufficient capital to execute its strategic plan and fund operations through at least the next 12 months from the date these Consolidated Financial Statements are issued.



## Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

## Item 9A. Controls and Procedures

## Evaluation of Disclosure Controls and Procedures

In designing and evaluating our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired controls. As required by Rule 13a-15(b) under the Exchange Act, our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered by this Report, our disclosure controls and procedures were effective.

## Inherent Limitations over Internal Control Over Financial Reporting

Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Our internal control over financial reporting includes those policies and procedures that:

- pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets;

- provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that the Company’s receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

- provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Management, including our principal executive officer and principal financial officer, does not expect that our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls in future periods are subject to the risk that those internal controls may become inadequate because of changes in business conditions, or that the degree of compliance with the policies or procedures may deteriorate.



## Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on our assessment, management has concluded that its internal control over financial reporting was effective as of December 31, 2022 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP.

Our independent registered public accounting firm, Ernst & Young LLP, has issued their report on our internal control over financial reporting, which appears in Part II, Item 8 of this Form 10-K.

## Changes in Internal Control over Financial Reporting

As previously disclosed in Part II, Item 9A in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, management previously identified a material weakness for Legacy Solid Power due to deficiencies identified in the operating effectiveness of controls over financial reporting related to the review of complex transactions for proper accounting treatment as our control environment would have failed to detect the misstatement prior to the financial statement issuance.

During 2022, we implemented our previously disclosed remediation plan, which included the following remediation actions:

• Hiring additional personnel.

• Improving our capabilities to identify, research, and prepare support documentation for technical accounting issues.

• Designing and implementing a formalized internal control framework.

• Improving and strengthening our control processes and procedures.

• Working with our auditors and other outside advisors to ensure that our controls and procedures are adequate and effective.

We have completed the necessary testing to conclude that the material weakness was remediated as of December 31, 2022. Except for the material weakness remediation described above, there were no changes during the fourth quarter of 2022 that were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

## Re: Confirmatory Employment Letter

Dear Josh:

This confirmatory employment letter agreement (the “Agreement”) is entered into between you and Solid Power, Inc.

In addition, nothing in this Agreement is intended to limit employees’ rights to discuss the terms, wages, and working conditions of their employment, nor to deny employees the right to disclose information pertaining to sexual harassment or any unlawful or potentially unlawful conduct, as protected by applicable law. You further understand that you are not permitted to disclose the Company’s attorney-client privileged communications or attorney work product. In addition, you acknowledge that the Company has provided you with notice in compliance with the Defend Trade Secrets Act of 2016 regarding immunity from liability for limited disclosures of trade secrets. The full text of the notice is attached in Exhibit B.

11. Miscellaneous. This Agreement, together with the Confidentiality Agreement, the Severance Agreement and the stock options granted to you by the Company under the Existing Equity Documents, constitute the entire agreement between you and the Company regarding the material terms and conditions of your employment, and they supersede and replace all prior negotiations, representations or agreements between you and the Company.

Executive Change in Control and Severance Plan and Participation Agreement

(see attached)



# EXECUTIVE CHANGE IN CONTROL AND SEVERANCE PLAN AND SUMMARY PLAN DESCRIPTION

1. Introduction. The purpose of this Solid Power, Inc. Executive Change in Control and Severance Plan (the "Plan"), effective as of August 4, 2021, (the "Effective Date") is to provide opportunities with respect to specified benefits to certain employees of the Company whose employment may be involuntarily terminated other than for death, Disability, or Cause or terminated by such employees for Good Reason under the circumstances described in the Plan. This Plan is an "employee welfare benefit plan," as defined in Section 3(1) of ERISA. This document is both the written instrument under which the Plan is maintained and the required summary plan description for the Plan.

2. Important Terms. The following words and phrases, when the initial letter of the term is capitalized, will have the meanings set forth in this Section 2, unless a different meaning is plainly required by the context:

2.1 “Administrator” means the Company, acting through the Compensation Committee or another duly constituted committee of members of the Board, or any person to whom the Administrator has delegated any authority or responsibility with respect to the Plan pursuant to Section 11, but only to the extent of such delegation.

2.2 “Board” means the Board of Directors of the Company.

2.3 “Cause” has the meaning set forth in the Participant’s Participation Agreement or, if no definition is set forth therein, means that one or more of the following has occurred: (i) the Participant’s conviction or indictment of, or plea of nolo contendere to, a felony or other crime involving moral turpitude; (ii) the Participant’s willful refusal to comply with the lawful requests made of him or her by the Company after written notice to him or her and the Participant’s failure to fully cure such willful refusal within a reasonable period of time of not fewer than thirty (30) days after such notice, unless such willful refusal is not reasonably susceptible of cure; (iii) material violation of the Company’s written policies, after written notice to the Participant from the Company of such violation and the Participant’s failure to fully cure such violation within a reasonable period of time of not fewer than thirty (30) days after such notice unless the violation is not reasonably susceptible of cure; or (iv) a material breach by the Participant of any material provision of any material agreement between the Participant and the Company or its subsidiaries after written notice to the Participant from the Company of such breach and the Participant’s failure to fully cure such breach within a reasonable period of time of not fewer than thirty (30) days after such notice, unless the breach is not reasonably susceptible of cure.

2.4 “Change in Control” means the occurrence of any of the following events:

(a) Change in Ownership of the Company. A change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection (a), the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered a Change in Control; provided, further, that any change in the ownership of the stock of the Company as a result



of a private financing of the Company that is approved by the Board also will not be considered a Change in Control. Further, if the stockholders of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in substantially the same proportions as their ownership of shares of the Company’s voting stock immediately prior to the change in ownership, direct or indirect beneficial ownership of fifty percent (50%) or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event will not be considered a Change in Control under this subsection (a). For this purpose, indirect beneficial ownership will include, without limitation, an interest resulting from ownership of the voting securities of one or more corporations or other business entities which own the Company, as the case may be, either directly or through one or more subsidiary corporations or other business entities; or

(b) Change in Effective Control of the Company. If the Company has a class of securities registered pursuant to Section 12 of the Exchange Act, a change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this subsection (b), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or

(c) Change in Ownership of a Substantial Portion of the Company’s Assets. A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such Person or Persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (c), the following will not constitute a change in the ownership of a substantial portion of the Company’s assets: (i) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (ii) a transfer of assets by the Company to: (A) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (B) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or indirectly, by the Company, (C) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (D) an entity, at least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a Person described in this subsection (c)(ii)(C). For purposes of this subsection (c), gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.

For purposes of this definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company.

Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Code Section 409A.

Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (x) its sole purpose is to change the jurisdiction of the Company’s incorporation, or (y) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction. In addition, the reference to “Company” in this definition shall be updated to the extent set forth in Section 20 of the Plan.

For clarity, the SPAC Closing shall not constitute a Change in Control under the Plan.



2.5 “Change in Control Period” means the time period beginning on the date that is 3 months prior to a Change in Control and ending on the date that is 12 months following a Change in Control.

2.6 “CIC Qualifying Termination” has the meaning set forth in a Participant’s Participation Agreement.

2.8 “Company” means (i) prior to the SPAC Closing, Solid Power, Inc., a Colorado corporation, and any successor that assumes the obligations of the Company under the Plan, by way of merger, acquisition, consolidation or other transaction, and (ii) on and following the SPAC Closing, Solid Power, Inc., a Delaware corporation (which entity, prior to the SPAC Closing, was known as DCRC (as defined below)), and any successor that assumes the obligations of the Company under the Plan, by way of merger, acquisition, consolidation or other transaction.

2.9 “Compensation Committee” means the Compensation Committee of the Board.

2.10 “Director” means a member of the Board.

2.11 “Disability” means “Disability” as defined in the Company’s long-term disability plan or policy then in effect with respect to that Participant, as such plan or policy may be in effect from time to time, and, if there is no such plan or policy, a total and permanent disability as defined in Code Section 22(e)(3).

2.13 “ERISA” means the Employee Retirement Income Security Act of 1974, as amended.

2.14 “Good Reason” has the meaning set forth in the Participant’s Participation Agreement or, if no definition is set forth therein, means the Participant’s resignation or departure from the Company (such that, as a result of such resignation or departure, the Participant is no longer employed by the Company or any of its affiliates) by reason of or following the occurrence of any of the following events without Participant’s express written consent: (i) a ten percent (10%) or greater reduction in Participant’s base salary (unless such reduction is part of a program involving comparable reductions in compensation levels of other management personnel of the Company (or its successor)); (ii) a material reduction in the Participant’s then currently assigned duties or responsibilities with the Company; or (iii) a relocation of the Participant’s principal location of employment to a location fifty (50) miles or further from the Participant’s principal location of employment as of the date Participant becomes a Participant in the Plan; provided, however, that any such event shall not constitute grounds for “Good Reason” unless (x) Participant provides written notice to the Company of the event claimed to constitute grounds for “Good Reason” within ninety (90) days of the initial existence of such event; (y) the Company fails to remedy such condition within thirty (30) days of receiving such written notice thereof (such period, the “Cure Period”); and (z) Participant actually terminates Participant’s employment not more than one hundred twenty (120) days following the initial existence of the event claimed to constitute grounds for “Good Reason”. For clarity, neither the SPAC Closing nor any changes to the Participant’s employer or duties and responsibilities, in either case, in connection with the SPAC Closing, shall constitute grounds for resignation of “Good Reason” under the Plan.



2.15 “Non-CIC Qualifying Termination” has the meaning set forth in a Participant’s Participation Agreement.

2.16 “Participant” means an employee of the Company or of any subsidiary of the Company who (a) has been designated by the Administrator to participate in the Plan either by position or by name, and (b) has timely and properly executed and delivered a Participation Agreement to the Company.

3. Eligibility for Severance Benefits. A Participant is eligible for Severance Benefits, as described in Section 4, only if he or she experiences a Qualifying Termination.

4. Qualifying Termination. Upon a Qualifying Termination, subject to the Participant’s compliance with Section 6, the Participant will be eligible to receive the following Severance Benefits as described in Participant’s Participation Agreement, subject to the terms and conditions of the Plan and the Participant’s Participation Agreement:

4.1 Cash Severance Benefits. Cash severance equal to the amount set forth in the Participant’s Participation Agreement.

4.2 Continued Medical Benefits. If the Participant, and any spouse and/or dependents of the Participant (“Family Members”) has or have coverage on the date of the Participant’s Qualifying Termination under a group health plan sponsored by the Company, the Company will reimburse the Participant the total applicable premium cost for continued group health plan coverage under the Consolidated Omnibus



Budget Reconciliation Act of 1985, as amended (“COBRA”) until the earliest of (a) the period of time following the Participant’s employment termination as set forth in the Participant’s Participation Agreement, (b) the date the Participant is no longer eligible to receive COBRA continuation coverage, and (c) the date on which Participant becomes eligible to receive coverage under a group health plan sponsored by another employer (and any such eligibility shall be promptly reported to the Company by Participant); provided that the Participant validly elects and is eligible to continue coverage under COBRA for the Participant and his Family Members. However, if the Company determines in its sole discretion that it cannot provide the COBRA reimbursement benefits without potentially violating applicable laws (including, without limitation, Section 2716 of the Public Health Service Act and the Employee Retirement Income Security Act of 1974, as amended), the Company will in lieu thereof provide to the Participant a lump sum payment equal to the monthly COBRA premium (on an after-tax basis) that the Participant would be required to pay to continue the group health coverage in effect on the date of the Participant’s termination of employment (which amount will be based on the premium for the first month of COBRA coverage), paid each month, regardless of whether the Participant elects COBRA continuation coverage, for the period of time following the Participant’s employment termination as set forth in the Participant’s Participation Agreement.

4.3 Equity Award Vesting Acceleration Benefit. Only to the extent specifically provided in the Participant’s Participation Agreement, a portion of Participant’s Equity Awards will vest and, to the extent applicable, become immediately exercisable.

5. Limitation on Payments. In the event that the severance and other benefits provided for in this Plan or otherwise payable to a Participant (i) constitute “parachute payments” within the meaning of Section 280G of the Code (“280G Payments”), and (ii) but for this Section 5, would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the 280G Payments will be either:

1. (x) delivered in full, or

2. (y) delivered as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by Participant on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. If a reduction in the 280G Payments is necessary so that no portion of such benefits are subject to the Excise Tax, reduction will occur in the following order: (i) cancellation of awards granted “contingent on a change in ownership or control” (within the meaning of Code Section 280G); (ii) a pro rata reduction of (A) cash payments that are subject to Section 409A as deferred compensation and (B) cash payments not subject to Section 409A of the Code; (iii) a pro rata reduction of (A) employee benefits that are subject to Section 409A as deferred compensation and (B) employee benefits not subject to Section 409A; and (iv) a pro rata cancellation of (A) accelerated vesting equity awards that are subject to Section 409A as deferred compensation and (B) equity awards not subject to Section 409A. In the event that acceleration of vesting of equity awards is to be cancelled, such acceleration of vesting will be cancelled in the reverse order of the date of grant of a Participant’s equity awards.

A nationally recognized professional services firm selected by the Company, the Company’s legal counsel or such other person or entity to which the parties mutually agree (the “Firm”) will make any determination required under this Section 5. Such determinations will be made in writing by the Firm and any good faith determinations of the Firm will be conclusive and binding upon Participant and the Company. For purposes of making the calculations required by this Section 5 the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. Participant and the Company will furnish to the Firm such information and documents as the Firm may reasonably request in order to make a determination under



this Section 5. The Company will bear all costs the Firm may incur in connection with any calculations contemplated by this Section 5.

## 6. Conditions to Receipt of Severance.

6.1 Release Agreement. As a condition to receiving the Severance Benefits (and any portion thereof), each Participant will be required to sign and not revoke in the time provided by the Company to do so a separation and release of claims agreement in a form reasonably satisfactory to the Company (the "Release"), which Release shall release the Company, each of its affiliates, and each of the foregoing entities' respective shareholders, members, partners, officers, managers, directors, predecessors, successors, fiduciaries, employees, representatives, agents and benefit plans (and fiduciaries of such plans) from any and all claims and any and all causes of action arising out of the Participant's employment, engagement, or affiliation with the Company or any of its affiliates or the termination of such employment, engagement or affiliation, but excluding (i) all claims to Severance Benefits that the Participant may be owed hereunder or any other consideration set forth in the Release, (ii) indemnification rights the Participant may have by reason of being a director or officer of the Company or subsidiary (or any related advancement of expenses, and/or contribution claims or rights the Participant may have), including any rights under any director and officer liability policy or indemnification agreement, (iii) rights to any accrued compensation or benefits that Participant may have, or (iv) any other rights or claims that Participant may have that may not be released under applicable law. In all cases, the Release must have become effective and irrevocable no later than the 60th day following the Participant's Qualifying Termination (the "Release Deadline Date"). If the Release does not become effective and irrevocable by the Release Deadline Date (or, if earlier, the time provided by the Company to consider, return, and not revoke the Release, as may be set forth within the Release itself), the Participant will forfeit any right to the Severance Benefits. In no event will the Severance Benefits be paid or provided until the Release becomes effective and irrevocable.

6.2 Confidential Information. A Participant’s receipt of, Severance Benefits will be subject to the Participant continuing to comply with the terms of any confidentiality, proprietary information and inventions agreement between the Participant and the Company (or any affiliate of the Company).

6.3 Non-Disparagement. As a condition to receiving Severance Benefits under this Plan, the Participant agrees that, following the Participant’s termination, the Participant will not knowingly disparage, libel, slander, or otherwise make any materially derogatory statements regarding the Company (or any of its affiliates) or any of their respective officers or directors. Notwithstanding the foregoing, nothing contained in the Plan will be deemed to restrict the Participant from (i) providing information to any governmental or regulatory agency or body (or in any way limit the content of any such information) to the extent the Participant is required to provide such information pursuant a subpoena or as otherwise required by applicable law or regulation, or in accordance with any governmental investigation or audit relating to the Company or (ii) making any other disclosures that are protected under the whistleblower provisions of any applicable law.

6.4 Other Requirements. Severance Benefits under this Plan shall terminate immediately for a Participant if such Participant, at any time, violates any agreement with the Company or its affiliates and/or the provisions of this Section 6.

7. Timing of Severance Benefits. Unless otherwise provided in a Participant’s Participation Agreement, provided that the Release has become effective and irrevocable by the Release Deadline Date and subject to Section 9, the Severance Benefits will be paid, or in the case of installments, will commence, on the first Company payroll date following the Release Deadline Date (such payment date, the “Severance Start Date”), and any Severance Benefits otherwise payable to the Participant during the period immediately



following the Participant’s termination of employment with the Company (or any parent or subsidiary or other Company affiliate), through the Severance Start Date will be paid in a lump sum (without interest) to the Participant on the Severance Start Date, with any remaining payments to be made as provided in this Plan and the Participant’s Participation Agreement.

8. Exclusive Benefit. Except as otherwise specifically provided in the Participant’s Participation Agreement, the Severance Benefits shall be the exclusive benefit for a Participant related to termination of employment with the Company (or any parent or subsidiary or other Company affiliate).

## 9. Section 409A.

9.1 Notwithstanding anything to the contrary in this Plan, no Severance Benefits to be paid or provided to a Participant, if any, under this Plan that, when considered together with any other severance payments or separation benefits, are considered deferred compensation under Section 409A of the Code, and the final regulations and any guidance promulgated thereunder (“Section 409A”) (together, the “Deferred Payments”) will be paid or provided until the Participant has a “separation from service” within the meaning of Section 409A. Similarly, no Severance Benefits payable to a Participant, if any, under this Plan that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until the Participant has a “separation from service” within the meaning of Section 409A.

9.2 It is intended that none of the Severance Benefits will constitute Deferred Payments but rather will be exempt from Section 409A as a payment that would fall within the “short-term deferral period” as described in Section 9(c) below or resulting from an involuntary separation from service as described in Section 9(d) below. In no event will a Participant have discretion to determine the taxable year of payment of any Deferred Payment.

9.3 Notwithstanding anything to the contrary in this Plan, if a Participant is a “specified employee” within the meaning of Section 409A at the time of the Participant’s separation from service (other than due to death), then the Deferred Payments, if any, that are payable within the first 6 months following the Participant’s separation from service, will become payable on the date 6 months and 1 day following the date of the Participant’s separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, in the event of the Participant’s death following the Participant’s separation from service, but before the 6 month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of the Participant’s death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Plan is intended to constitute a separate payment under Section 1.409A-2(b)(2) of the Treasury Regulations.

9.4 Any amount paid under this Plan that satisfies the requirements of the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of this Section 9.

9.5 Any amount paid under this Plan that qualifies as a payment made as a result of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit will not constitute Deferred Payments for purposes of this Section 9.

9.6 The foregoing provisions are intended to comply with or be exempt from the requirements of Section 409A so that none of the Severance Benefits will be subject to the additional tax



imposed under Section 409A, and any ambiguities herein will be interpreted to so comply or be exempt. Notwithstanding anything to the contrary in the Plan, including but not limited to Sections 11 and 13, the Company reserves the right to amend the Plan as it deems necessary or advisable, in its sole discretion and without the consent of the Participants, to comply with Section 409A or to avoid income recognition under Section 409A prior to the actual payment of Severance Benefits or imposition of any additional tax. In no event will the Company reimburse a Participant for any taxes or other costs that may be imposed on the Participant as a result of Section 409A.

10. Withholdings. The Company (or any parent or subsidiary or other Company affiliate employing Participant) will withhold from any Severance Benefits all applicable U.S. federal, state, local and non-U.S. taxes required to be withheld and any other required payroll deductions.

11. Administration. The Company is the administrator of the Plan (within the meaning of section 3(16)(A) of ERISA). The Plan will be administered and interpreted by the Administrator (in his or her sole discretion). The Administrator is the “named fiduciary” of the Plan for purposes of ERISA and will be subject to the fiduciary standards of ERISA when acting in such capacity. Any decision made or other action taken by the Administrator with respect to the Plan, and any interpretation by the Administrator of any term or condition of the Plan, or any related document, will be conclusive and binding on all persons and be given the maximum possible deference allowed by law. In accordance with Section 2(a), the Administrator (a) may, in its sole discretion and on such terms and conditions as it may provide, delegate in writing to one or more officers of the Company all or any portion of its authority or responsibility with respect to the Plan, and (b) has the authority to act for the Company (in a non-fiduciary capacity) as to any matter pertaining to the Plan; provided, however, that any Plan amendment or termination or any other action that reasonably could be expected to increase materially the cost of the Plan must be approved by the Board.

12. Eligibility to Participate. To the extent that the Administrator has delegated administrative authority or responsibility to one or more officers of the Company in accordance with Sections 2(a) and 11, each such officer will not be excluded from participating in the Plan if otherwise eligible, but he or she is not entitled to act upon or make determinations regarding any matters pertaining specifically to his or her own benefit or eligibility under the Plan. The Administrator will act upon and make determinations regarding any matters pertaining specifically to the benefit or eligibility of each such officer under the Plan.

13. Term. Subject to the terms of this paragraph, this Plan will have a term of 2 years commencing on the Effective Date (the "Initial Term"). At the end of the Term, this Plan will renew automatically for additional one year terms (each, an "Additional Term" and together with the Initial Term, the "Term") unless the Administrator provides the Participant notice of non-renewal at least 30 days prior to the date of automatic renewal. The Administrator may decide to sooner terminate this Plan before the end of the Term in accordance with Section 14 below or if the affected Participant consents to an earlier termination. Any termination of this Plan by the Administrator must be in writing and will be taken in a non-fiduciary capacity. Neither the lapse of this Plan by its terms nor the termination of this Plan by the Company will by itself constitute termination of employment or grounds for a Good Reason. Further, if a Change in Control occurs when there are fewer than 3 months remaining during the Term, the Term will extend automatically through the date that is 12 months following the date of the Change in Control (unless the affected Participant consents to an earlier termination). Notwithstanding the foregoing, if during the Term, an initial occurrence of an act or omission by the company constituting the grounds for "Good Reason" in accordance with the definition herein has occurred (the "Initial Grounds"), and the expiration date of the Cure Period (as such defined herein) with respect to such Initial Grounds could occur following the expiration of the Term, the Term will extend automatically through the date that is 30 days following the expiration of the Cure Period, but such extension of the Term will only apply with respect to the Initial Grounds.



14. Amendment or Termination. The Company, by action of the Administrator, reserves the right to amend or terminate the Plan at any time, without advance notice to any Participant and without regard to the effect of the amendment or termination on any Participant or on any other individual; provided, however, that any amendment or termination of the Plan that is materially detrimental to a Participant prior to such amendment or termination of the Plan will not be effective with respect to such Participant without such Participant’s prior written consent. Any amendment or termination of the Plan will be in writing. Notwithstanding the foregoing, any amendment to the Plan that (a) causes an individual to cease to be a Participant, or (b) reduces or alters to the detriment of the Participant the Severance Benefits potentially payable to that Participant (including, without limitation, imposing additional conditions or modifying the timing of payment), will not be effective without that Participant’s written consent. Any action of the Company in amending or terminating the Plan will be taken in a non-fiduciary capacity.

## 15. Claims and Appeals.

15.1 Claims Procedure. Any employee or other person who believes he or she is entitled to any Severance Benefits may submit a claim in writing to the Administrator within 90 days of the earlier of (i) the date the claimant learned the amount of his or her Severance Benefits or (ii) the date the claimant learned that he or she will not be entitled to any Severance Benefits. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Plan on which the denial is based. The notice also will describe any additional information needed to support the claim and the Plan’s procedures for appealing the denial. The denial notice will be provided within 90 days after the claim is received. If special circumstances require an extension of time (up to 90 days), written notice of the extension will be given within the initial 90-day period. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision on the claim.

15.2 Appeal Procedure. If the claimant’s claim is denied, the claimant (or his or her authorized representative) may apply in writing to the Administrator for a review of the decision denying the claim. Review must be requested within 60 days following the date the claimant received the written notice of their claim denial or else the claimant loses the right to review. The claimant (or representative) then has the right to review and obtain copies of all documents and other information relevant to the claim, upon request and at no charge, and to submit issues and comments in writing. The Administrator will provide written notice of its decision on review within 60 days after it receives a review request. If additional time (up to 60 days) is needed to review the request, the claimant (or representative) will be given written notice of the reason for the delay. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Plan on which the denial is based. The notice also will include a statement that the claimant will be provided, upon request and free of charge, reasonable access to, and copies of, all documents and other information relevant to the claim and a statement regarding the claimant’s right to bring an action under Section 502(a) of ERISA.

16. Attorneys’ Fees. The Company and each Participant shall each bear their own expenses, legal fees and other fees incurred in connection with this Plan and any claim for benefits hereunder.

17. Source of Payments. All payments under the Plan will be paid from the general funds of the Company; no separate fund will be established under the Plan, and the Plan will have no assets. No right of any person to receive any payment under the Plan will be any greater than the right of any other general unsecured creditor of the Company.



18. Inalienability. In no event may any current or former employee of the Company or any of its subsidiaries or affiliates sell, transfer, anticipate, assign or otherwise dispose of any right or interest under the Plan. At no time will any such right or interest be subject to the claims of creditors nor liable to attachment, execution or other legal process.

19. No Enlargement of Employment Rights. Neither the establishment or maintenance or amendment of the Plan, nor the making of any benefit payment hereunder, will be construed to confer upon any individual any right to continue to be an employee of the Company or any of its affiliates for any particular period of time, as nothing herein alters the at-will employment relationship between any Participant and the Company or, if applicable, any of its affiliates. The Company expressly reserves the right to discharge any of its employees at any time, with or without cause. However, as described in the Plan, a Participant may be entitled to Severance Benefits depending upon the circumstances of his or her termination of employment.

20. Successors. Any successor to the Company of all or substantially all of the Company’s business and/or assets (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or other transaction) will assume the obligations under the Plan and agree expressly to perform the obligations under the Plan in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under the Plan, the term “Company” will include any successor to the Company’s business and/or assets which become bound by the terms of the Plan by operation of law, or otherwise, and specifically with respect to the “Change in Control” definition, will mean the ultimate parent of any such successor, unless otherwise determined by the Administrator prior to such purchase, merger, consolidation, liquidation or other transaction.

21. Applicable Law. The provisions of the Plan will be construed, administered and enforced in accordance with ERISA and, to the extent applicable, the internal substantive laws of the state of Colorado (but not its conflict of laws provisions).

22. Severability. If any provision of the Plan is held invalid or unenforceable, its invalidity or unenforceability will not affect any other provision of the Plan, and the Plan will be construed and enforced as if such provision had not been included.

23. Headings. Headings in this Plan document are for purposes of reference only and will not limit or otherwise affect the meaning hereof.

24. Indemnification. The Company hereby agrees to indemnify and hold harmless the officers and employees of the Company, and the members of its Board, from all losses, claims, costs or other liabilities arising from their acts or omissions in connection with the administration, amendment or termination of the Plan, to the maximum extent permitted by applicable law. This indemnity will cover all such liabilities, including judgments, settlements and costs of defense. The Company will provide this indemnity from its own funds to the extent that insurance does not cover such liabilities. This indemnity is in addition to and not in lieu of any other indemnity provided to such person by the Company.

26. Statement of ERISA Rights.

As a Participant under the Plan, you have certain rights and protections under ERISA:

1. You may examine (without charge) all Plan documents, including any amendments and copies of all documents filed with the U.S. Department of Labor. These documents are available for your review in the Company’s human resources department.

2. You may obtain copies of all Plan documents and other Plan information upon written request to the Administrator. A reasonable charge may be made for such copies.

In addition to creating rights for Participants, ERISA imposes duties upon the people who are responsible for the operation of the Plan. The people who operate the Plan (called “fiduciaries”) have a duty to do so prudently and in the interests of you and the other Participants. No one, including the Company or any other person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a benefit under the Plan or exercising your rights under ERISA. If your claim for a severance benefit is denied, in whole or in part, you must receive a written explanation of the reason for the denial. You have the right to have the denial of your claim reviewed. (The claim review procedure is explained in Section 14 above.)

Under ERISA, there are steps you can take to enforce the above rights. For example, if you request materials and do not receive them within 30 days, you may file suit in a federal court. In such a case, the court may require the Administrator to provide the materials and to pay you up to $110 a day until you receive the



materials, unless the materials were not sent due to reasons beyond the control of the Administrator. If you have a claim which is denied or ignored, in whole or in part, you may file suit in a federal court. If it should happen that you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a federal court.

In any case, the court will decide who will pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds that your claim is frivolous.

If you have any questions regarding the Plan, please contact the Administrator. If you have any questions about this statement or about your rights under ERISA, you may contact the nearest area office of the Employee Benefits Security Administration (formerly the Pension and Welfare Benefits Administration), U.S. Department of Labor, listed in your telephone directory, or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue, N.W. Washington, D.C. 20210. You also may obtain certain publications about your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.



Appendix A

Participation Agreement

(see attached)



# Solid Power, Inc. Executive Change in Control and Severance Plan

Solid Power, Inc. (the “Company”) is pleased to inform you, the undersigned that you have been selected to participate in the Company’s Executive Change in Control and Severance Plan (the “Plan”) as a Participant.

A copy of the Plan was delivered to you with this Participation Agreement. Your participation in the Plan is subject to all of the terms and conditions of the Plan. The capitalized terms used but not defined herein will have the meanings ascribed to them in the Plan.

The Plan describes in detail certain circumstances under which you may become eligible for Severance Benefits. As described more fully in the Plan, you may become eligible for certain Severance Benefits if you experience a Qualifying Termination.

1. Non-CIC Qualifying Termination. Upon your Non-CIC Qualifying Termination, subject to the terms and conditions of the Plan, you will receive:

(a) Cash Severance Benefits. A lump sum payment equal to 6 months of your base salary (less applicable withholding taxes).

(b) Continued Medical Benefits. Your reimbursement of continued health coverage under COBRA or taxable lump sum payments in lieu of reimbursement, as applicable, and as described in Section 4.2 of the Plan will be provided for a period 6 months following the date of your Qualifying Termination.

2. CIC Qualifying Termination. Upon your CIC Qualifying Termination, subject to the terms and conditions of the Plan, you will receive:

(a) Cash Severance Benefits. A lump sum payment equal to the sum of: (i) 12 months of your base salary plus (ii) 100% of your annual target bonus in effect for the year of the CIC Qualifying Termination (less applicable withholding taxes).

(b) Continued Medical Benefits. Your reimbursement of continued health coverage under COBRA or taxable lump sum payments in lieu of reimbursement, as applicable, and as described in Section 4.2 of the Plan, will be provided for a period of 12 months following the date of your Qualifying Termination.

(c) Equity Award Vesting Acceleration. 100% of your then-outstanding and unvested Equity Awards will become vested in full and, to the extent applicable, become immediately exercisable (it being understood that forfeiture of any equity awards due to termination of employment will be tolled to the extent necessary to implement this section (c)). If, however, an outstanding Equity Award is to vest and/or the amount of the award to vest is to be determined based on the achievement of performance criteria, then the Equity Award will vest as to 100% of the amount of the Equity Award assuming the performance criteria had been achieved at target levels for the relevant performance period(s).

## 3. Definitions.

(a) CIC Qualifying Termination. “CIC Qualifying Termination” means your termination of employment with the Company (or any parent or subsidiary of the Company) within the Change in Control Period by (i) you for Good Reason, or (ii) the Company (or any parent or subsidiary of the



Company) without Cause (excluding by reason of your death or Disability) such that, as a result of any termination described in this definition, you are no longer employed by the Company or any of its affiliates.

(b) Non-CIC Qualifying Termination. “Non-CIC Qualifying Termination” means your termination of employment with the Company (or any parent or subsidiary of the Company) outside the Change in Control Period by (i) you for Good Reason, or (ii) the Company (or any parent or subsidiary of the Company) without Cause (excluding by reason of your death or Disability) such that, as a result of any termination described in this definition, you are no longer employed by the Company or any of its affiliates.

4. Non-Duplication of Payment or Benefits. If (a) your Qualifying Termination occurs prior to a Change in Control that qualifies you for Severance Benefits under Section 1 of this Participation Agreement and (b) a Change in Control occurs within the 3-month period following your Qualifying Termination that qualifies you for the superior Severance Benefits under Section 2 of this Participation Agreement, then (i) you will cease receiving any further payments or benefits under Section 1 of this Participation Agreement and (ii) the Cash Severance Benefits, Continued Medical Benefits, and Equity Award Vesting Acceleration, as applicable, otherwise payable under Section 2 of this Participation Agreement each will be offset by the corresponding payments or benefits you already received under Section 1 of this Participation Agreement in connection with your Qualifying Termination (if any).

5. Exclusive Benefit. In accordance with Section 8 of the Plan, the benefits, if any, provided under this Plan will be your exclusive benefits related to the termination of your employment with the Company and/or a change in control of the Company and will supersede and replace any severance and/or change in control benefits set forth in any offer letter, employment or severance agreement and/or other agreement between the Participant and the Company or any of its affiliates. For the avoidance of doubt, the Plan shall not supersede or replace any change in control provisions set forth in the Company’s 2014 Equity Incentive Plan, as amended and the applicable award agreements thereunder or any equity-based plan, and those provisions shall continue to apply with respect to your outstanding Company equity awards in effect prior to the Effective Date.

In order to receive any Severance Benefits for which you otherwise become eligible under the Plan, you must timely sign and deliver to the Company the Release, which must have become effective and irrevocable within the requisite period, and otherwise comply with the requirements under Section 6 of the Plan.

By your signature below, you and the Company agree that your participation in the Plan is governed by this Participation Agreement and the provisions of the Plan. Your signature below confirms that: (1) you have received a copy of the Executive Change in Control and Severance Plan and Summary Plan Description; (2) you have carefully read this Participation Agreement and the Executive Change in Control and Severance Plan and Summary Plan Description and you acknowledge and agree to its terms in accordance with the terms of the Plan and this Participation Agreement; and (3) decisions and determinations by the Administrator under the Plan will be final and binding on you and your successors.

# SEPARATION AND RELEASE AGREEMENT

This SEPARATION AND RELEASE AGREEMENT (this “Agreement”), dated as of the last date on the signature page of this Agreement, is between Solid Power Operating, Inc. (together with its parent company, Solid Power, Inc., collectively the “Company”) and Jon Jacobs (“Employee”) (collectively, the “parties”).

## Agreement

In consideration of the mutual promises and covenants contained in this Agreement, the receipt and sufficiency of which is expressly acknowledged, the parties hereby agree as follows:

1. Separation. By mutual agreement of Employee and the Company, Employee’s employment with the Company is terminated effective as of February 8, 2023 (the “Separation Date”). Effective as of the Separation Date, Employee ceases to hold any position with the Company, whether as an officer, employee, representative, agent, or otherwise.

## 2. Accrued Obligations:

(a) Final Wages. The Company agrees to pay Employee final wages earned through the Separation Date, in each case less legally required deductions and withholdings. Employee will receive these payments regardless of whether Employee signs this Agreement.

(b) Unemployment Insurance Benefits. Employee is eligible to apply for unemployment insurance benefits. Provided that Employee accurately reports Employee’s dates of employment and compensation, the Company shall not contest any claim Employee may file for unemployment insurance benefits. Whether or not Employee receives any unemployment insurance benefits is determined in the sole discretion of the applicable state agency, not the Company.

(c) Insurance. Employee’s health insurance benefits will cease on February 28, 2023. To the extent permitted by either the federal Consolidated Omnibus Budget Reconciliation Act or state law (“COBRA”), and the insurance policies and rules applicable to the Company, Employee will be eligible to continue Employee’s health insurance benefits at Employee’s own expense after that date. Company shall provide Employee with the appropriate notification form setting forth the Employee’s rights and responsibilities with regard to continued health insurance coverage.

## 3. Other Compensation.

(a) Additional Consideration. In exchange for: (i) Employee signing and returning this Agreement to the Company on or within 21 calendar days from the date Employee receives it and allowing it to become effective in accordance with its terms, (ii) Employee agreeing to the Non-Solicit Covenants (defined below), and (iii) Employee complying with the terms of this Agreement and the PIAA (defined below), the Company shall pay to Employee an amount equal to 12 months of Employee’s current monthly base pay, which equates to a total sum of $305,000, less all legally required deductions and withholdings (“Additional Consideration”). The Additional Consideration shall be paid to Employee on a ratable bi-weekly basis during the 12-month period applicable to the Non-Solicit Covenants in accordance with the Company’s normal payroll procedures; provided, however, that no Additional Consideration shall be earned or due to Employee if the Company determines that Employee has breached the Non-Solicit Covenants or any of Employee’s obligations under the PIAA or this Agreement at any time prior to the date on which the Additional Consideration is paid.

(b) COBRA Premiums. The Company shall pay to Employee $10,379.40, less all legally required deductions and withholdings, which is an amount equal to Employee’s premiums to continue Employee’s group health insurance coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act (“COBRA Premiums”) for a period of six months following the Separation Date. The



COBRA Premiums will be paid in one lump sum payment on the Company’s first regularly-scheduled payroll date following the 60th day after the Separation Date, provided that, prior to such date, the Company has received this signed Agreement from Employee and it has become effective as set forth in Section 10(e) below.

(c) No Further Compensation. As the termination of Employee’s employment was by the mutual agreement of the parties hereto, Employee acknowledges Employee is not entitled to any benefits or payments under the Solid Power, Inc. Executive Change in Control and Severance Plan (“Plan”) or any participation agreement thereunder and Employee expressly waives the same. Employee acknowledges that Employee has received all compensation to which Employee is entitled, including wages. Employee also acknowledges that Employee is not aware of any fact that would support a claim for unpaid wages. Employee acknowledges and agrees that, as of the Separation Date, Employee will cease to be a participant in the Plan.

4. Denial of Liability. The parties acknowledge that the Additional Consideration provided by the Company and the release of claims by Employee pursuant to this Agreement are made in compromise of any potential disputes, that in making such payment or release, the Company and Employee in no way admit any liability to each other and that the parties expressly deny any such liability.

5. Non-Disparagement. Employee agrees that Employee has not and will not disparage, slander, make any libelous or derogatory statements about, or attempt to harm the personal or business reputation of, the Company or the Company’s owners, managers, agents, employees, officers, or directors, or otherwise attempt to interfere with or impair the Company’s business relationships. This non-disparagement provision extends to any form of communication, whether oral, written, or in any electronic form, including via social media and through communications with current or former employees of the Company. Nothing in this Section, this Agreement, or any other agreement entered into with the Company: (a) will be interpreted or construed to prevent Employee or the Company from giving truthful information to any law enforcement officer, court, administrative proceeding or as part of an investigation by any government agency, (b) is intended to prohibit or restrain Employee or the Company in any manner from making disclosures that are protected under federal law or regulation or under other applicable law or regulation (including disclosures that are protected under the whistleblower provisions of any federal or state law), and/or (c) prevents Employee from discussing or disclosing employee wages, benefits or terms and conditions of employment or information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that Employee has reason to believe is unlawful (foregoing activities described in the preceding clauses (a)-(c) shall be referred to in this Agreement as the “Protected Communications”).

6. Company Property. Employee represents and warrants that Employee has returned to the Company all Company documents and all copies thereof and any and other Company property in Employee’s possession, custody, or control, including financial information, customer information, customer lists, employee lists, files, notes, cellular telephones, contracts, drawings, records, business plans and forecasts, specifications, computer-recorded information, electronically stored information, software, computer equipment (with all data and files stored thereon intact), tangible property, credit cards, entry cards, identification badges and keys, and any other materials, documents, or things of any kind which contain or embody any proprietary or confidential material of the Company and all reproductions thereof.

7. Confidential and Proprietary Information/Non-Disclosure. Employee agrees and acknowledges that Employee continues to be bound by the confidentiality and non-disclosure terms outlined in the Confidential Information, Invention Assignment and Arbitration Agreement, dated September 30, 2021, between Employee and the Company, a copy of which is attached to this Agreement as Exhibit A (the “PIAA”).

(a) Notwithstanding anything in the PIAA to the contrary, to the fullest extent permitted under applicable law, and in order to protect the Company’s Trade Secrets (as defined in the PIAA), Employee hereby agrees that during the 12-month period following the Separation Date,



Employee will not directly or indirectly (i) solicit any of the Company’s actual customers or vendors with which Employee has had any contact at any time during Employee’s employment to cease doing business with the Company, to reduce the quantity of their business with the Company or to purchase products or services that are competitive with the business of the Company; or (ii) solicit, induce, recruit or encourage any of the Company’s employees, contractors or consultants to terminate their relationship with the Company or to become employed or engaged as a consultant by Employee or any third party (subclasses (i) and (ii), the “Non-Solicit Covenants”).

(b) Notwithstanding anything to the contrary in this Section, this Agreement, or any in the PIAA, Employee acknowledges that the Company has advised Employee that Employee will not be held civilly or criminally liable under any federal or state trade secret law for the disclosure of a trade secret that: (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding; or (c) is made to an attorney or is used in a court proceeding in connection with a lawsuit alleging retaliation for reporting a suspected violation of law, provided that the trade secret is filed under seal and not disclosed except pursuant to court order.

8. Confidentiality. The provisions of this Agreement will be held in strictest confidence by Employee and will not be publicized or disclosed by Employee in any manner whatsoever. Notwithstanding the prohibition in the preceding sentence: (a) Employee may disclose this Agreement in confidence to Employee’s attorneys, accountants, auditors, tax preparers, and financial advisors, provided that such persons will be informed of the existence of this confidentiality obligation and will agree to be bound thereby to the same extent as Employee; and (b) Employee may disclose this Agreement insofar as such disclosure may be necessary to enforce its terms or as otherwise required by law.

## 9. Covenant Not to Sue and Release of Claims by Employee.

(a) In consideration for the Separation Benefits set forth in this Agreement and the mutual covenants of the parties, Employee agrees to unconditionally release from and covenant not to sue or assert against the Company and all of its past and present parent companies, subsidiaries, related entities, shareholders, directors, members, trustees, officers, current and former employees, agents, insurers, attorneys, predecessors, successors, and assignees (collectively, the “Releases”), all causes of action, claims, liabilities, and obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or omissions occurring prior to or on the date Employee signs this Agreement, including (without limitation) (i) all claims pertaining to or arising from the employment relationship of the parties and the termination of such employment relationship, (ii) all claims pertaining to or arising from Employee’s compensation or benefits from the Company, including salary, bonuses, incentive compensation, commissions, paid time off, expense reimbursements, severance or change in control benefits under the Plan or otherwise, notice rights, retention benefits, fringe benefits, stock, stock options, units, or any other ownership interests in the Company; (iii) all claims for breach of contract (oral or written), wrongful termination, and breach of the implied covenant of good faith and fair dealing; (iv) all tort claims, including claims for fraud, inducement, misrepresentation, defamation, emotional distress, and discharge in violation of public policy; (v) all constitutional, federal, state, and local statutory and common law claims, including, but not limited to, claims for discrimination, harassment, retaliation, interference, attorneys’ fees, and/or other claims arising under: (A) Title VII of the Civil Rights Act of 1964, as amended; (B) the Colorado Anti-Discrimination Act; (C) the Family and Medical Leave Act; (D) the Americans with Disabilities Act; (E) the Families First Coronavirus Response Act; (vi) all claims arising from any theory under common law, such as breach of contract, express or implied; promissory estoppel; detrimental reliance; wrongful discharge; tortious interference with contract rights; infliction of emotional distress; and defamation; and (vii) all claims for attorneys’ fees and costs. The parties intend this waiver to be interpreted and applied as broadly as possible.

(b) This Agreement does not affect the Employee’s right to engage in any Protected Communications or to file a charge with, communicate with, or participate in an investigative or other



proceeding before the Occupational Safety and Health Administration, the Securities and Exchange Commission, the Equal Employment Opportunity Commission, state civil rights agency, or another federal, state, or local government agency or to communicate or cooperate with any such agency in its investigation or proceedings, none of which shall constitute a breach of this Agreement. While this Agreement does not limit Employee’s right to receive an award for information provided to the Securities and Exchange Commission, Employee understands and agrees that, to maximum extent permitted by law, Employee is expressly waiving Employee’s right to any relief, recovery, attorney fees, or other monies in connection with any such complaint, charge, or proceeding brought against the Releasees, regardless of who filed or initiated any such complaint, charge, or proceeding.

(c) Causes of action as used in this Section 9 means all claims, causes, judgments, damages, losses, liabilities, and demands of any kind, whether intentional or negligent, known or unknown, in law or in equity, individually or as part of a class or collective action, occurring on or prior to the date of execution of this Agreement, arising under any constitution, federal, state, or local law(s).

(d) The general release and covenant not to sue does not apply to claims under federal, state, or local law (statutory, regulatory, or otherwise) that may not be lawfully waived and released, including vested retirement benefits (if any), COBRA rights, unemployment compensation, and workers’ compensation.

(e) Further, nothing in this Agreement is intended to release Employee’s right, if any, to continuing health insurance, rights under the 2014 Equity Incentive Plan, the 2021 Equity Incentive Plan, the 2021 Employee Stock Purchase Plan, or 401(k) plan. Further, the Company makes no representations as to Employee’s rights under any benefit plans, including the 2014 Equity Incentive Plan, the 2021 Equity Incentive Plan, the 2021 Employee Stock Purchase Plan, or 401(k) plan.

10. Age Discrimination in Employment Act and Older Workers Benefit Protection Act Release. In addition to the General Release contained in Section 9, Employee knowingly and voluntarily discharges and releases Releasees from any claims arising under the Age Discrimination in Employment Act. Employee acknowledges that Employee has been informed pursuant to the Older Workers Benefit Protection Act that:

(a) Employee is advised to consult with an attorney before signing this Agreement.

(b) Employee does not waive rights or claims under the Age Discrimination in Employment Act that may arise after the date this Agreement is executed.

(c) Employee has 21 days from the date of receipt of this Agreement to consider this Agreement. Employee acknowledges that if Employee signs this Agreement before the end of the 21-day period, it will be Employee’s personal, voluntary decision to do so, and that Employee has not been pressured to make a decision sooner. Employee further agrees and acknowledges that any changes to this Agreement, whether material or immaterial, do not restart the 21-day period.

(d) Employee has seven days after signing this Agreement to revoke this Agreement, and this Agreement will not be effective until that revocation period has expired. If mailed, the rescission must be postmarked within the seven-day period, properly addressed to Stacy Morse of the Company’s Human Resources Department [***].

(e) This Agreement shall not be effective or enforceable, and no payments or benefits under this Agreement shall be provided, until after the seven day revocation period has expired.

Employee hereby authorizes the Company to release such information in response to any inquiries from third parties concerning Employee. Employee will direct all prospective employers to contact Company’s Chief Legal Officer.

13. Covenant Not to Seek Reemployment. Employee agrees that Employee will not apply for or seek employment or reemployment with the Company.

14. Applicable Law; Binding Arbitration; Injunctive Relief.

(a) This Agreement will be governed by the laws of Colorado without reference to conflict of laws principles.

(b) Any controversy arising out of or relating to this Agreement or the breach or threatened breach of this Agreement, or any claim or action to enforce this Agreement or portion thereof, or any controversy or claim requiring interpretation of this Agreement must be brought in accordance with the arbitration provisions set forth in Section 12 of Exhibit B to the PIAA, the terms of which are incorporated herein, mutatis mutandis.

(c) Employee agrees that Employee’s breach or threatened breach of this Agreement will entitle the Company, in addition to any other remedy available at law or in equity, to recover the Additional Consideration from Employee as liquidated damages and not as a penalty, with the remaining monetary consideration serving as valid consideration for this Agreement. Because of the difficulty of ascertaining damages in the event of a breach of this Agreement, in addition to any other remedy available at law or in equity, Employee expressly agrees the Company also may enforce the provisions of this Agreement through injunctive relief and Employee agrees the Company will not be required to establish any irreparable injury other than the breach of this Agreement. The Company will not be required to post any bond or surety, which Employee hereby waives.

15. Section 409A. It is intended that all of the Additional Consideration and other payments payable under this Agreement satisfy, to the greatest extent possible, the exemptions from the application of the US Internal Revenue Code Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this Agreement will be construed to the greatest extent possible as consistent with those provisions, and to the extent not so exempt, this Agreement (and any definitions hereunder) will be construed in a manner that complies with Section 409A. For purposes of Code Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), Employee’s right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this Agreement, if Employee is deemed by the Company at the time of Employee’s Separation Date to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and if any of the payments upon “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)) set forth herein and/or under any other agreement with the Company are deemed to be “deferred compensation,” then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i) and the related adverse taxation under Section 409A, such payments shall not be provided to Employee prior to the earliest of (i) the expiration of the six-month period measured from the date of Employee’s Separation from Service with the Company, (ii) the date of Employee’s death or (iii) such earlier date as permitted under Section 409A without the imposition of



adverse taxation. Upon the first business day following the expiration of such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section shall be paid in a lump sum to Employee, and any remaining payments due shall be paid as otherwise provided herein or in the applicable agreement. No interest shall be due on any amounts so deferred.

16. Successors and Further Assurances. The parties agree that by entering into this Agreement they do not intend to confer any benefits privileges or rights to others. Subject to the successors and assigns listed below, this Agreement is strictly between the parties, and it will not be construed to vest in any other the status of third-party beneficiary. This Agreement will bind and inure to the benefit of the heirs, personal representatives, successors, assigns, executors, and administrators of each party. The parties agree to perform any lawful additional acts, including the execution of additional agreements, as are reasonably necessary to effectuate the purpose of this Agreement.

17. Miscellaneous. This Agreement, along with the PLAA, the 2014 Equity Incentive Plan Stock Option Grant Notice and Option Agreement, and the 2021 Equity Incentive Plan Notice of Restricted Stock Unit Grant and Restricted Stock Unit Agreement (which are separate agreements and obligations and shall remain in full force and effect in accordance with their terms following the Separation Date), is the entire agreement between the parties relating to the subject matter of this Agreement. No modification of this Agreement will be valid unless in writing signed by each party. No waiver of rights arising under this Agreement is effective unless made expressly in writing by the party waiving such rights. If any provision of this Agreement is held by a court of competent jurisdiction to be contrary to law, the remaining provisions of this Agreement will remain in full force and effect. The term “including” is deemed to mean “including, without limitation” when used in this Agreement. The terms “herein,” “hereunder” and similar terms when used in this Agreement mean under and within this Agreement. All references to Sections and Exhibits in this Agreement refer to Sections and Exhibits in this Agreement. This Agreement may be executed and delivered by each party in separate counterparts, each of which when so executed and delivered shall be deemed an original and all of which taken together shall constitute one and the same Agreement. This Agreement, and any amendments to this Agreement, to the extent signed and delivered by means of PDF or other electronic transmission, shall be treated in all manner and respects as an original contract and shall be considered to have the same binding legal effects as if it were the original signed version thereof delivered in person. Any such signature page shall be effective as a counterpart signature page to this Agreement without regard to page, document, or version numbers or other identifying information, which are for convenience of reference only. At the request of a party, the other party shall re-execute original forms thereof and deliver them to the other party.

18. Acknowledgments by Employee. By signing below, Employee acknowledges and agrees that: (i) Employee has carefully reviewed and understands this Agreement; (ii) Employee has been given a reasonable amount of time to review and consider the Agreement; (iii) Employee enters into and signs this Agreement voluntarily; (iv) the release and waivers Employee has made are knowing, conscious, and with full appreciation that Employee is forever foreclosed from pursuing any of the rights or claims so waived; (v) the promises made by the Company herein constitute sufficient and legal consideration for Employee's agreement hereunder and are in addition to anything of value to which Employee is already entitled; and (vi) Employee understands that if Employee does not return this Agreement, signed by Employee, by March 2, 2023, this offer will expire.
