Evolving or unfavorable global trade policies, including tariffs, trade barriers and export/import regulations related to the battery and EV industry and other industries in which we may pursue.

Previous wording

Developing lithium-metal solid-state batteries that meet the requirements for wide adoption by automotive OEMs is a difficult undertaking and, as far as we are aware, has never been done before. We are still in the development stage and face significant challenges in completing the development of our battery cells and in producing battery cells in volumes with acceptable performance, quality, consistency, reliability, throughput, safety, and costs. Some of the development challenges include increasing the quality, consistency, reliability and production throughput of our separators and cells, increasing the size and layer count of our multilayer cells, increasing production scale to produce the volume of cells needed for our technology development and customer applications, installing, bringing up and optimizing higher throughput equipment, packaging design and engineering to ensure adequate cycle life, pressure management, cost reduction, completion of the rigorous and challenging specifications required by our automotive partners, including but not limited to, calendar life, energy density, mechanical, safety, and abuse testing.

Previous wording

We have installed a pilot line in San Jose, California, which serves as the foundation for our production ramp-up. We must successfully operate this line to provide a sufficient quantity of high-quality separators and cells for internal development, customer sampling and testing, and higher volumes of QSE-5 cells. Ultimately, we need to continue the build out and ramp up of our pilot line to serve as the basis for continued production process development, including to support collaboration and future technology transfer activities as part of the collaboration and licensing arrangements with PowerCo as well as potential future commercial arrangements. However, we could encounter significant delays and cost overruns related to planning, permitting, construction, equipment delivery, installation, qualification, and utilities infrastructure installation, and operations ramp-up of our pilot line, including due to factors related to its design and execution. Examples include global supply chain issues that impact our equipment suppliers, supplier non-performance and equipment damage in transit. In particular, we have experienced short-term power outages at our San Jose facilities that have been resolved, but similar disruptions may occur in the future; delays associated with material shortage and backups at key shipping ports could impact the capacity at which we can run the facility; and certain of our construction contractors have previously reported delays, including due to labor strikes of their employees that were ultimately resolved but may reoccur in the future. If we, or our partners, are unable to substantially improve our production processes to increase yield and throughput to achieve the cost, reliability, performance and volume levels required for commercial shipments, our business could be materially impacted. The readiness of our pilot line and our investments in automation do not eliminate the risks associated with equipment integration and reliability, yield instability, supplier performance and availability, or delays and difficulties in transferring and scaling our production processes to our partners’ facilities, any of which could delay or prevent the commercialization of our technology and materially and adversely affect our business.

Previous wording

We rely on third-party suppliers for components and equipment necessary to develop and manufacture our solid-state batteries, including key supplies, such as our cathode material and manufacturing equipment for both our solid-state separator and battery cells. We are collaborating with key suppliers but have not yet entered into agreements for the supply of production quantities for many of these materials. To the extent that we are unable to enter into commercial agreements with these suppliers on beneficial terms, or these suppliers experience difficulties or delays ramping up their supply of materials to meet our requirements, the commercialization of our battery technology will be delayed. For example, we have previously experienced minor disruptions to the supply of process gas and have also experienced and could continue to experience disruption to the supply of petroleum-derived products as a result of certain weather and geopolitical events and conflicts and any related political or economic responses and counter-responses or otherwise by various global actors. The global conflicts in Russia, Iran and the Middle East, among others, have led to an increase in the price of petroleum and petroleum-derived products, which has in certain instances increased and may in the future further increase the cost of manufacturing, input material pricing and logistics costs. These challenges may be exacerbated in situations where we source certain of our materials and equipment exclusively from one or a few suppliers.

Previous wording

Currency fluctuations, trade barriers, tariffs or shortages and other general economic or political conditions may limit our ability to obtain key materials, components or equipment for our solid-state batteries 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. In particular, tariffs and trade barriers, whether imposed as part of trade disputes, protective measures, or broader geopolitical strategies, could substantially increase the cost or negatively affect the availability of components and materials critical to our operations, disrupting operations or putting significant pressure on our overall cost structure or that of our partners. For example, in February 2026, the United States imposed additional tariffs on all imports into the United States, with certain limited exceptions, for a period of 150 days. These tariffs, any additional tariffs imposed on foreign goods, as well as retaliation by a foreign government against such tariffs or policies may affect, directly or indirectly, the prices and supply of key materials necessary for our or our supply chain operations. Such developments may also create uncertainty in the supplier landscape, causing suppliers to reassess their own sourcing strategies or delay shipments, further impacting our ability to plan and execute on our operational goals. We may also be subject to a number of geopolitical risks, including U.S. and foreign government trade restrictions or sanctions and any political or economic responses or counter-responses to such restrictions or sanctions. As global competition for raw materials continues to intensify, particularly in light of rising demand for battery technologies, including due to policy-driven market instability or the reallocation of global supply in response to protectionist measures, we may face difficulties securing critical supplies on favorable terms or at all, which could materially harm our ability to produce batteries at scale and threaten the viability of our business.

Previous wording

Many of our potential customers tend to be large enterprises that often undertake a significant evaluation process and are frequently subject to budget constraints, multiple approvals and unanticipated administrative, processing and other delays, that result in a lengthy sales or licensing cycle. Therefore, our future success will depend on our ability to effectively sell our products or license our technology 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, including a greater ability to push back on attempts to pass on increased operating and procurement costs and require provisions that can lead to a delay in revenue recognition, (ii) longer sales and implementation cycles and the associated risk that substantial time and resources may be spent on a potential end-customer that elects not to purchase our solutions, and (iii) greater product functionality and scalability requirements, including a broader range of services. There are also only a limited number of OEMs in the automotive sector. All of these factors can add further risk to business conducted with these potential customers.

Previous wording

In July 2024, we entered into the Collaboration Agreement with the goal of PowerCo industrializing QS technology based on QSE-5. Under the Collaboration Agreement, the parties agreed to collaborate to enable PowerCo to manufacture battery cells incorporating QS technology based on QSE-5, including through a joint scale-up team that was established to facilitate the transfer of such technology into a cell size determined by PowerCo and by carrying out the activities set forth in statements of work. In connection therewith and subject to the completion of certain milestones, the parties intend to enter into the PowerCo IP License Agreement under which we will grant PowerCo a non-exclusive, limited, royalty-bearing license to use the QS technology based on QSE-5 for the purpose of manufacturing and selling batteries primarily for automotive applications, initially at one or more PowerCo facilities that together have an annual capacity of up to 40 GWh, expandable by an additional 40 GWh of annual capacity or such other capacity as may be agreed to by the parties.

Previous wording

In July 2025, we entered into the PowerCo Amendment and a statement of work outlining the scope and responsibilities of the joint scale-up team. As part of the PowerCo Amendment, the terms of the PowerCo IP License Agreement have been amended to provide PowerCo the right to produce up to an additional 5 GWh of QS battery cell technology based on QSE-5 annually, including for customers outside the Volkswagen Group, bringing the potential maximum production by PowerCo under the PowerCo IP License Agreement to 85 GWh annually. In July 2026, we and PowerCo entered into an amendment (the “2026 Amendment”) to the PowerCo Amendment to update the program structure and milestones. The 2026 Amendment replaces the prior statement of work and related cost reimbursement structure with payments based on the achievement of milestones, including the delivery and validation of battery cells over the next two years. Under the 2026 Amendment, the maximum aggregate amount we will receive from PowerCo for the program is $75.4 million, inclusive of amounts paid to date.

Current wording

We and PowerCo have amended the PowerCo Collaboration Agreement in July 2025 and July 2026, including to amend the terms of the PowerCo IP License Agreement to provide PowerCo the right to produce up to an additional 5 GWh of QS battery cell technology based on QSE-5 annually, including for customers outside the Volkswagen Group, bringing the potential maximum production by PowerCo under the PowerCo IP License Agreement to 85 GWh annually, and to update the program structure and milestones. In October 2026, we further amended the PowerCo Collaboration Agreement to, among other things, remove transition payments due from PowerCo and enter into negotiations for a revised scope of work and payments, including our current and next generation technology roadmap and applications beyond automotive. During this negotiation period, PowerCo will not make milestone payments for the Project.

Previous wording

There is no assurance that we will be able to complete the development of the solid-state battery cells or achieve the technical milestones in the time frame required by the PowerCo Collaboration Agreement or to satisfy PowerCo’s business needs, or that the joint scale-up team will cooperate successfully or complete in a timely and cost-effective manner the responsibilities assigned to them under the PowerCo Collaboration Agreement. If we are not able to reach certain milestones under the PowerCo Collaboration Agreement, PowerCo has no obligation to enter into the PowerCo IP License Agreement and we will not receive the initial royalty fee otherwise due to us thereunder and will not realize any of the benefits otherwise expected from this agreement. Additionally, continued billings to PowerCo are subject to completion of certain technical milestones or other contractual payment schedules, and therefore our results may vary significantly from quarter to quarter. There can be no assurance that the joint scale-up team will complete certain technical milestones or that PowerCo will pay for the project. Any reduction, delay, or termination of the collaboration or this project or its funding could disrupt our development timelines, impact on our engagements with other customers and partners, and materially impact our business and financial results. The amounts of royalties to be paid under the PowerCo IP License Agreement, if entered into, will depend on the performance of our solid-state battery and the demand for the vehicles that Volkswagen develops specifically to use with the solid-state battery cells produced under the PowerCo IP License Agreement. If we cannot complete the development of our solid-state battery cells, if PowerCo does not select our solid-state battery cell for commercialization or if there is a delay in the introduction of the Volkswagen vehicles that intend to use our solid-state battery cells, our business will be harmed.

If we are not able to reach certain milestones under the PowerCo Collaboration Agreement, PowerCo has no obligation to enter into the PowerCo IP License Agreement and may, in certain circumstances, terminate the PowerCo Collaboration Agreement. In these cases, we will not receive the initial royalty fee otherwise due to us under the PowerCo Collaboration Agreement and will not realize any of the benefits otherwise expected from such agreements. Additionally, continued payments by PowerCo are subject to completion of certain technical milestones or other contractual payment schedules, and therefore our results may vary significantly from quarter to quarter. There can be no assurance that the joint scale-up team will complete certain technical milestones or that we will receive any further payments from PowerCo in connection with the Project. Certain technical milestones have not been achieved within the contemplated time frames and the corresponding payments will not be paid to us. Any reduction, delay, failure to successfully negotiate a revised scope of work, or termination of the PowerCo Collaboration Agreement or its funding could disrupt our development timelines, impact our engagements with other customers and partners, and materially impact our business and financial results.

Previous wording

Volkswagen is our largest shareholder and holds the right to designate two directors to our Board. The strong relationship that we have developed with Volkswagen, including as a shareholder, and PowerCo and rights under the PowerCo Collaboration Agreement and, if entered into, the PowerCo IP License Agreement, may deter other automotive OEMs from working closely with us. While the PowerCo IP License Agreement, if entered into, would be non-exclusive, allowing us to license our intellectual property to other third parties, we may still need to incur significant additional expenditures for design, development, and testing to meet the needs of these third parties. If we are not able to expand our other customer relationships to a license or commercialization intent, or if we become too dependent on Volkswagen for our revenue, our business could be harmed. Volkswagen may have economic, business or legal interests or goals that are inconsistent with our goals. For example, adverse conditions in the EV market have led Volkswagen to reduce planned capital investments in their overall electrification efforts, which may delay, scale back, or otherwise adversely affect our collaboration and planned commercialization of our battery technology. Further, the existence of a related-party arrangement could raise concerns among investors, analysts, or regulators about potential conflicts of interest or the independence of our governance practices. In addition, the contractual arrangements with PowerCo involves complex accounting judgments under U.S. GAAP (as defined below). Any significant disagreements with Volkswagen may impede our ability to maximize the benefits of our relationship, slow the commercialization of our solid-state battery and impact on our relationship with other customers and partners. In addition, if PowerCo is unable or unwilling to meet its economic or other obligations under the PowerCo Collaboration Agreement and PowerCo IP License Agreement, if entered into, we may be required to terminate such agreements and thereby may not realize any of the benefits otherwise expected from such agreements. These factors could result in a material adverse effect on our business and financial results. While we have entered into the PowerCo Collaboration Agreement, we cannot predict the extent to which PowerCo’s activities may pose a competitive risk to, or otherwise be in conflict with, our business.

Our success in expanding into new markets also depends on our ability to establish and maintain commercial relationships, which may include new and existing strategic partners, licensees, or other collaborators. There can be no assurance that we will be able to identify and establish relationships and arrangements with partners in such new markets. In addition, these new and existing relationships may require significant management attention and resources and may expose us to operational, financial, or reputational risks.

Previous wording

We incurred a loss from operations of approximately $106.1 million and $215.3 million, and a net loss of approximately $98.2 million and $199.0 million for the three and six months ended June 30, 2026, respectively, and an accumulated deficit of approximately $4.0 billion from our inception in 2010 through June 30, 2026. We believe that we will continue to incur operating losses each quarter until at least the time significant production of our lithium-metal solid-state batteries begins, and such production is not expected to begin in the near future.

Current wording

Previous wording

Our batteries, and the sale of EVs and motor vehicles in general, are subject to substantial regulations under international, federal, state and local laws, including U.S. and non-U.S. export controls, sanctions and other trade compliance laws. We expect to incur significant costs in complying with these regulations. Regulations related to the battery and EV industry and alternative energy are currently evolving and we face risks associated with changes to these regulations as well as the potential for heightened regulatory scrutiny and enforcement activity. For example, laws and regulations may be passed that make manufacturers financially responsible for the collection, treatment, recycling and disposal of certain products, including batteries for EVs, or that impose restrictions on the sourcing of raw materials or components from certain jurisdictions or suppliers. The costs of complying with such requirements, as they now exist or as may be introduced in the future, and the associated administrative burden could adversely affect our financial condition and results of operations, particularly if we are unable to pass on such costs to our customers or if we’re negatively impacted to obtain the components and materials critical to our operations from global suppliers. In addition, compliance with trade laws may require us to obtain licenses, restrict sales to certain customers, distributors, or jurisdictions, or implement controls on the use, resale, or transfer of our products and services, any of which could delay or prevent transactions and increase our operating costs.

Current wording

Our batteries, and the sale of EVs and motor vehicles in general, as well as other products and applications incorporating our technology that we are pursuing, are subject to substantial regulations under international, federal, state and local laws, including U.S. and non-U.S. export controls, sanctions and other trade compliance laws. We expect to incur significant costs in complying with these regulations. Regulations related to the battery and EV industry and alternative energy, and other industries in which we may seek to commercialize our technology, are currently evolving and we face risks associated with changes to these regulations as well as the potential for heightened regulatory scrutiny and enforcement activity. For example, laws and regulations may be passed that make manufacturers financially responsible for the collection, treatment, recycling and disposal of certain products, including batteries for EVs, or that impose restrictions on the sourcing of raw materials or components from certain jurisdictions or suppliers. The costs of complying with such requirements, as they now exist or as may be introduced in the future, and the associated administrative burden could adversely affect our financial condition and results of operations, particularly if we are unable to pass on such costs to our customers or if we’re negatively impacted to obtain the components and materials critical to our operations from global suppliers. In addition, compliance with trade laws may require us to obtain licenses, restrict sales to certain customers, distributors, or jurisdictions, or implement controls on the use, resale, or transfer of our products and services, any of which could delay or prevent transactions and increase our operating costs.

In addition, the complex relationships between the United States and the countries in which we may conduct business pose inherent risks, including that political, diplomatic, and national security factors may result in global trade restrictions and changes in trade policies and export regulations that affect the EV industry. As geopolitical conflicts, such as the wars in Ukraine and in the Middle East, and broader global trade tensions, continue or escalate, they may lead to further disruption, instability and volatility in global markets and industries that could negatively impact our operations, supply chain, and future sales. The U.S. government and other governments have already imposed severe sanctions and export controls against Russia and Belarus, as well as against entities in China and other countries that are supporting Russia’s invasion of Ukraine, and may impose additional measures in the future. The impact of these measures, as well as potential responses to them by Russia, China, and other countries, is currently unknown and they could adversely affect the global economy, our business, supply chain, partners or customers.

The U.S. government has and may continue to make significant changes in U.S. trade policy, including further expanding its controls on exports and imposing new tariffs on imports globally, which could negatively impact U.S. trade and result in the adoption of retaliatory tariffs by other countries, leading to heightened trade tensions and potential disruption to global trade flows. More specifically, the U.S. government has imposed significant tariffs on and prohibited imports of products from China, as well as increased scrutiny of imports through customs enforcement and supply chain traceability requirements. In retaliation, China has implemented additional tariffs on a wide range of American products, imposed controls on exports of rare earth minerals to the United States and may impose additional tariffs and controls on inputs used by the EV industry. Such tariffs and prohibitions, if expanded, could have a significant impact on our business, adversely affect supply chains, and may impact our ability to access materials or production equipment in a timely manner, including around the importation of parts of our batteries and certain production equipment that is manufactured in, or with inputs from, China. If we attempt to renegotiate prices with suppliers or diversify our supply chain in response to tariffs, such efforts may not yield immediate results or may be ineffective, and alternative suppliers may be limited or more costly. We might also consider increasing prices to our customers once we commence sales of our products; however, this could reduce the competitiveness of our products and adversely affect net sales.

We cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and other countries, what products may be subject to such actions, or what actions may be taken by other countries in retaliation. If we fail to manage these dynamics successfully, gross margins and profitability could be adversely affected. As of the date of this report, tariffs have not had a material impact on our business, but should there be further disruption, instability and volatility in global markets and industries resulting from the dynamics of geopolitical relations between the United States and China, or the United States and other countries, our business could be materially and adversely affected, including due to volatility of prices and lead times of equipment and materials sourced from or with a supply chain passing through China and other impacted countries.

As of June 30, 2026, our executive officers, directors and their affiliates as a group and each of our stockholders who own 10% or more of our outstanding Class A Common Stock or our Class B Common Stock (together, the “Common Stock”), in the aggregate, beneficially own approximately 14.4% of our Class A Common Stock and approximately 100% of our Class B Common Stock outstanding, representing approximately 44.6% of the vote. As a result, these stockholders, including Volkswagen, will be able to exercise a significant level of control over all matters requiring stockholder approval, including the election of directors, any amendment of our Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and approval of significant corporate transactions. In addition, Volkswagen holds the right to designate two directors to our Board. Currently, Dr. Günther Mendl, Head of the Center of Excellence Battery at Volkswagen AG, and Sebastian Schebera, Head of Strategic Partnerships at Volkswagen AG, are members of our Board. This control could have the effect of delaying or preventing a change of control or changes in our management and will make the approval of certain transactions difficult or impossible without the support of these stockholders and of their votes. Further, shares of Class B Common Stock have 10 votes per share, while shares of Class A Common Stock have one vote per share. Even though the holders of our Class B Common Stock are not party to any agreement that requires them to vote together, they may have interests that differ from yours and may vote in a way with which you disagree, and which may be adverse to your interests. This concentrated control may have the effect of delaying, preventing or deterring a change in control of us, could deprive our stockholders of an opportunity to receive a premium for their capital stock as part of a sale of us, and might ultimately affect the market price of shares of our Class A Common Stock.

Our success depends on our ability to attract and retain our executive officers, key employees and other qualified personnel. Achieving this objective may be difficult due to many factors, including fluctuations in global economic and industry conditions, management or organizational changes, the availability of qualified employees, evolving immigration and export control policies and restrictions, the attractiveness of our compensation and benefit programs, our career growth and development opportunities, and our employment policies. Specifically, 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. None of our employees are bound by a non-competition agreement. The failure to attract, integrate, train, motivate and retain these personnel could seriously disrupt our operations and harm our business and prospects. Further, any future reduction in force may yield unintended consequences, such as making future retention and recruiting of qualified personnel more difficult, attrition beyond our planned reduction in workforce, decline in employee productivity and reduced employee morale, which may cause our remaining employees to seek alternative employment.

The Inflation Reduction Act of 2022 (the “IRA”) included numerous incentives and tax credits aimed at reducing the effects of climate change, such as the extension and expansion of EV charging infrastructure tax credits under Section 30C of the Internal Revenue Code of 1986 (the “Code”), the expansion of tax credits for EVs under Section 30D of the Code, the expansion of advanced manufacturing facility tax credits under Section 48C of the Code, and enactment of advanced manufacturing production credits for eligible component production in the United States under Section 45X of the Code. Such tax credits may potentially benefit incumbents more than new entrants, and consequently have adverse competitive effects for new entrants. However, several of these provisions were modified by the OBBBA. The Section 30D credit terminated on September 30, 2025, and the Section 30C credit will terminate on July 30, 2026.

Pursuant to the Sarbanes-Oxley Act and the rules and regulations promulgated by the SEC, we are required to furnish in this Report a report by our management regarding the effectiveness of our internal control over financial reporting. The report includes, among other things, an assessment of the effectiveness of our internal control over financial reporting as of the end of our fiscal year, including a statement as to whether or not our internal control over financial reporting is effective. This assessment must include disclosure of any material weaknesses in our internal control over financial reporting identified by management. While we believe our internal control over financial reporting is currently effective, we have previously identified and had to remediate a material weakness and the effectiveness of our internal controls in future periods is subject to the risk that our controls may become inadequate because of changes in conditions. Establishing, testing and maintaining an effective system of internal control over financial reporting requires significant resources and time commitments on the part of our management and our finance staff, which may require additional staffing and infrastructure investments and would increase our costs of doing business.

Our business involves complex financial transactions, including but not limited to stock-based compensation, lease accounting, and income tax provisions. The accounting rules and regulations governing these areas are frequently changing and require significant judgment in their application. As our operations grow in scale and complexity, the risk of material errors or omissions in our financial statements increases. For example, in July 2025, we amended the Collaboration Agreement with the goal of funding certain part of the research and development under the PowerCo Collaboration Agreement. The arrangement involved complex accounting judgments under U.S. GAAP, including classification of payments received from PowerCo with no contractually stated repayment terms as a liability, as well as derecognition of the liability to shareholders’ equity upon extinguishment, driven by the significant related party relationship with Volkswagen Group, which creates a presumption of a repayment obligation.
