PART I

Item 1. Business

Overview

SES AI Corporation (“we,” “us,” “SES” or the “Company”) is a global leader in the development and production of high-performance, Lithium-Metal (“Li-Metal”) rechargeable battery technologies for electric vehicles (“EVs”), electric vehicle take-off and landing (“eVTOL”) and other applications. SES Holdings Pte. Ltd., and Subsidiaries (“Old SES”) was founded in 2012, and our mission is to facilitate the widespread adoption of sustainable electric transportation, both on land and in air, by creating best-in-class, high energy density Li-Metal batteries centered around long-range performance and safety.

We have developed what we believe to be the world’s most advanced Li-Metal battery technology, and we have the management team in place to become a leading provider of batteries. Our third-party tested, differentiated battery technology has been designed to combine the high energy density of Li-Metal with the cost-effective, large-scale manufacturability of conventional Lithium-ion (“Li-ion”) batteries and will help to promote the transition from the global dependence on fossil fuel-based automotive vehicles to clean and efficient EVs.

We believe that our Li-Metal batteries demonstrate industry-leading energy density and performance and will:

Limitations of Current Battery Technology

Conventional Li-ion technology is currently being used in most commercially available EVs. Li-ion typically uses a metal oxide-based or phosphate-based cathode and graphite or graphite/silicon-based anodes. The anode and cathode are separated by a polymer-based separator. Finally, the whole cell is filled with a liquid electrolyte that conducts lithium ions from the anode to the cathode as the vehicle is being driven (or battery is being discharged), and from the cathode to the anode as the vehicle (or the battery) is being charged. Conventional Li-ion cells have been instrumental in kick starting the current EV market, and are being manufactured at scale at capacities of hundreds of GWh today. However, the automotive industry desires a battery with higher energy density to improve the electric driving range (the distance that a vehicle can be driven on a single charge) while reducing battery cost to enable mass-adoption.

Li-Metal Batteries

Li-Metal is widely considered and accepted as the EV battery technology capable of achieving the highest energy density. In fact, switching the current Li-ion graphite/silicon anode with Li-Metal will currently result in the highest possible energy density for any given cathode in lithium chemistry. Li-Metal is the lightest un-engineered pure metal on earth and since the lithium ions do not have to diffuse in and out of the anode host material (like in the case of graphite or silicon in conventional Li-ion), the battery cells made with Li-Metal anode can be very compact and light. This combination of a lightweight and compact anode results in the highest possible gravimetric (Watt-hour (“Wh”)/kg) and volumetric (Wh/liter) energy density, respectively, for any given cathode in lithium chemistry.

One approach to Li-Metal, known as “solid-state Li-Metal,” primarily relies on solid-state materials. The solid-state material refers to the phase (solid) within which lithium ions transport from anode to cathode (during discharge) or from cathode to anode (during charge). Conventional Li-ion technology uses liquid electrolytes (not solid electrolytes), and such lithium ion transport is in the liquid phase. Approaches that use solid electrolytes generally suffer from either not having sufficient conductivity at room and lower than room temperatures, poor interface between electrolyte and electrode, inability to suppress lithium dendrites when the solid electrolyte film is thin, and lack of demonstrated manufacturability of thin, large format films and multi-layer cells at scale.

Our Technology

SES’s approach to Li-Metal preserves the high energy density benefits of Li-Metal while utilizing a cell design that primarily uses a liquid electrolyte in the cathode and separator to transport the lithium ions. There is also a protective anode coating between the anode and the separator, which consists of solid-state electrolyte materials. Hence, we call our approach “Li-Metal,” as it utilizes both liquid and solid electrolyte in the cell simultaneously. This approach results not only in improved energy density due to using a Li-Metal anode, but also superior performance at room and lower than room temperatures, and enables manufacturing at scale just like Li-ion, which is manufactured at scale today. In fact, we have been successfully making multi-Amp-hour (“Ah”), multi-layer cells using our Li-Metal approach for many years.

The key breakthrough in SES’s Li-Metal cells is its proprietary and patented liquid electrolyte. This electrolyte is developed internally at SES with many years of scientific research and development. We use a high-concentration, solvent-in-salt electrolyte. While liquid electrolytes used in conventional Li-ion cells are volatile and flammable, SES’s liquid electrolyte has low volatility and is self-extinguishing. Conventional liquid electrolytes are primarily made up of organic solvents with low concentrations of salt to aid lithium ion conduction. SES’s liquid electrolyte primarily consists of salt with a very minute amount of proprietary solvent molecules. This new type of high-concentration solvent-in-salt liquid electrolyte is fundamentally different from conventional liquid electrolyte. It maintains the manufacturability advantage of liquid electrolytes in conventional Li-ion manufacturing, but can enable Li-Metal due to its stability on lithium metal.

SES’s Li-Metal technology also helps resolve an issue that has plagued Li-Metal adoption and progress for decades. With repeated charge and discharge cycles, lithium metal anodes are known to develop needle-like mossy structures known as dendrites, which can penetrate the separator and short-circuit the battery cell. The use of our liquid electrolyte changes the morphology of dendrite formation in our Li-Metal battery cells from needle-like mossy structures to a smooth lithium metal surface or dense deposition. Our proprietary anode coating provides an added layer of protection against separator penetration by making lithium plating denser during charging. Additionally, our advanced AI-powered safety software and BMS monitors the state-of-health of the battery cells and can accurately detect any safety issues much earlier. The combination of these elements significantly increases cell cycle life and safety.

The rest of the cell is assembled using our proprietary ultra-thin wide-width Li-Metal anode, a conventional state-of-the-art separator and a cathode. With the exception of the Li-Metal anode, all materials and components utilized in our battery cells are either already being manufactured at scale or have the capability to be easily manufactured at scale without the need for intensive research and development, or development of new equipment.

To our knowledge, SES Li-Metal battery cells are the only Li-Metal cells demonstrated to meet or exceed the preliminary OEM target requirements for energy density, low temperature discharge, room temperature fast charge and discharge, cycle life and safety.

Our unique high-energy density Li-Metal battery is expected to be:

Our Competitive Strengths

Differentiated Battery Technology

As described above, our Li-Metal batteries are expected to be lighter, more energy dense, safer, faster-charging, and lower cost solution than Li-ion batteries, and to include smart technology. Our Li-Metal battery technology has projected energy density of 400 Wh/kg / 1,000 Wh/L in our large 100 Ah cells, compared to approximately 265 Wh/kg / 535 Wh/L in Li-ion battery cells using a high mickel content cathode. This higher energy density is expected to translate into significantly more range, which we believe will help to enable the expansion of an electrified world. Currently, our 100 Ah multi-layer battery cells have demonstrated energy density of 380 Wh/kg / 850 Wh/L in third-party testing, along with fast charging up to an 80% charge in less than 15 minutes, bolstering our confidence in our ability to achieve industry-leading performance. Our batteries are expected to be cheaper in the long-term, while providing fast-charge capabilities, best-in-class durability and a high degree of safety.

Designed For Manufacturing At Scale

Over the last 10 years of research and development, we have strived to develop a technology that is not only differentiated, but also scalable and manufacturable. We are producing our large 50 and 100 Ah cells using Li-ion production lines.

Strategic Partnerships

We believe that our products will experience swift market adoption due to our current strategic partnerships with leading global OEMs GM, Hyundai and Honda. To our knowledge, we are the only company working on Li-Metal technology that has entered into A-Sample joint development agreements (“JDAs”) with major OEMs for EVs. We plan to collaborate with other OEMs to expedite such adoption and increase market acceptance of our Li-Metal battery over time.

Our Growth Strategy

Battery Development for OEMs. We are currently working to develop and initially produce A-Sample batteries with specifications required by OEMs for their EVs, with the goal of achieving the development and initial production of B-Sample batteries in 2023 and C-Sample batteries in 2024, which we expect to enable us to commence commercial production of our technology in 2025. For more information on collaborations with these OEMs, see “Our Partnerships” below. A-Sample batteries are functional prototypes developed for OEMs based on their technical specifications. These are in contrast with B-Sample batteries, which are A-sample batteries manufactured under much higher throughput and tested in actual vehicles, and C-Sample batteries, which would be fully functional, mature samples for mass production and tested for full drivability in actual vehicles. As we remain focused on A-Sample battery development, we do not yet have any arrangements with OEMs to manufacture consumer-ready batteries for their EVs.

Battery Manufacturing At Scale. We will continue to enhance our production processes to enable volume manufacturing in a cost-effective manner. Phase I of our pilot facility in Shanghai was completed and ready-to-use in March 2022 and fully operational in the third quarter of 2022, and our pilot facility in South Korea was completed and ready-to-use in September 2022. We expect to expand our facilities in Shanghai and South Korea in 2023, and work with our OEM partners to build facilities for eventual C-Sample battery development and production ahead of this planned commercial production.

Partnership Development and Expansion. We will continue to strengthen our partnerships with GM, Hyundai and Honda in the use of our battery technology. Also, we intend to work closely with other OEMs and other strategic partners to develop and produce our Li-Metal battery cells, with the aim of making them widely available in EVs and other applications over time.

Supply Chain. As we plan to transition from A-sample to B-sample, we are exploring opportunities for partial vertical integration both upstream and downstream to ensure scalability. Vertical integration is used by Li-ion battery cell makers to reduce their costs, increase their competitiveness and streamline product development and commercialization for OEMs, by acquiring upstream and downstream participants in their supply chains. Upstream, we intend to explore integrating vendors of key materials of our cells and providers of key equipment and engineering capabilities, such as cell assembly, anode processing, chemical processing and safety testing. Downstream, we plan to explore integrating providers of key engineering capabilities, such as battery state-of-health monitoring software, charging optimization software, battery module development and recycling.

Continued Battery Innovation. We intend to continue leveraging our world-class science, engineering and manufacturing expertise to innovate future products that will continue to provide leading technology coupled with manufacturability. We continue to invest in research

and development in areas such as cell chemistry and structure, battery materials, AI software and advanced manufacturing, to build on our intellectual property portfolio.

Our Partnerships

We intend to work closely with OEMs and other strategic partners to develop and produce our Li-Metal battery cells, with the aim of making them widely available in EVs over time.

Existing JDAs

We have maintained a strong partnership with GM since 2015, when GM led our Series B financing, and since then, GM has invested approximately $70.0 million in our company, including a $50.0 million investment in our Series D funding round and a $10.0 million investment in the private placement transaction in connection with the Business Combination (the “PIPE Financing”), via GM’s affiliates and subsidiaries. GM is one of the world’s largest car companies, and has voiced its desire to be a leader in EVs. GM has announced plans to launch more than 30 new EV models by 2025 and only sell zero-emission vehicles by 2035. Our partnership initially involved close technical and research and development collaboration on SES’s battery technology. In February 2021, we entered into a JDA with GM, valued at over $50.0 million, under which we are collaborating to jointly develop an A-Sample battery cell with a capacity of almost 100 Ah.

We have also fostered a partnership with Hyundai, another global automobile leader and in December 2020, we entered into a pre-A-Sample JDA. In May 2021, Hyundai made an investment of $50.0 million in our Series D plus funding round and signed an A-Sample JDA, under which we are collaborating to jointly develop an A-Sample battery cell. We believe the Hyundai JDAs align our interests with those of Hyundai and will facilitate further collaboration in designing and developing our technology and products. Hyundai also purchased $50.0 million of our Class A common stock in the PIPE Financing.

In December 2021, Honda became the third global automobile leader to enter into an A-Sample JDA with us, under which we are collaborating to develop an A-Sample battery cell. Honda also purchased $75.0 million of our Class A common stock in the PIPE Financing as the single largest PIPE Financing investor.

The JDAs with GM, Hyundai and Honda do not represent commitments by these OEMs to purchase our Li-Metal battery cells, and are focused on development. Although the JDAs set timeframes for the attainment of certain development milestones, these timeframes are objectives only and may be subject to ongoing collaboration and change by the parties. The JDAs also do not prohibit GM, Hyundai, Honda or SES from entering into additional agreements with other third parties. To our knowledge, neither GM, Hyundai nor Honda has entered into new agreements with other automotive or battery companies for the development of A-Sample Li-Metal batteries.

Our Research and Development

We conduct research and development at our facilities in Woburn, Massachusetts in the United States, Shanghai, China, and Chungju, South Korea, and we expect to eventually build additional facilities in other parts of the world. Research and development activities concentrate on making further improvements to our battery technology, including improvements to battery performance and cost.

Major development efforts include, but are not limited to, programs in the following areas.

Competition

The battery market, like the EV market it services, is fast-growing, extremely competitive and driven by the innovation of both large incumbents and emerging entrants like SES. With the introduction of new technologies and the potential entry of new competitors into the market, we expect competition to increase in the future, which could harm our business, results of operations, or financial condition.

10

Table of Contents

Our prospective competitors include major manufactures supplying the industry, automotive OEMs and potential new entrants to the industry. Existing suppliers of batteries to the EV industry include Contemporary Amperex Technology Co. Limited, SK Innovation, LG Energy Solutions, Panasonic Corporation and Samsung SDI. Although their offerings tend to be conventional Li-ion, they could develop Li-Metal batteries that would directly compete with our offerings. Additionally, many automotive OEMs, including Tesla, Nio, Rivian and Toyota, are researching and investing in efforts to develop their own EV battery production capabilities.

Newer entrants, including Northvolt, Sila Nanotechnologies, Solid Power, QuantumScape, Ganfeng Lithium and WeLion, are also seeking to improve conventional lithium-ion batteries or to develop new technologies, including lithium-metal and solid-state batteries, or to develop new technologies for cathodes, anodes, electrolytes and additives. Some of these companies have established relationships with automotive OEMs and are in varying stages of development.

We acknowledge that incumbents and emerging entrants may have greater resources to invest in advancing their technologies, access to more potential customers, or strategic relationships with OEMs (or other third parties) that may give them a competitive edge. We further acknowledge that these disparities, where they exist, have the potential to harm our business, results of operations or financial condition.

Government Regulation and Compliance

There are government regulations pertaining to battery safety, transportation of batteries, use of batteries in vehicles, factory safety and disposal of hazardous materials. We will ultimately have to comply with these regulations to sell our batteries into the market. For more information, see “Risk Factors—Risks Relating to Regulations and Our Compliance With Such Regulations” discussing regulations and regulatory risks related to export controls (including our export controls compliance program), environmental, health and safety, anti-corruption, anti-bribery, data collection, trade and tax law compliance.

​

Item 1A. Risk Factors

We have identified the following risks and uncertainties that may have a material adverse effect on our business, financial condition, results of operations or reputation. The risks described below are not the only risks we face. Additional risks not presently known to us or that we currently believe are not material may also significantly affect our business, financial condition, results of operations or reputation. Our business could be harmed by any of these risks. The risk factors described below should be read together with the other information set forth in this Annual Report, including our consolidated financial statements and the related notes, as well as in other documents that we file with the SEC.

Risks Relating to Our Business and Technology

We face significant challenges in developing a Li-metal battery that can be commercialized for use in EVs and other applications, and the pace of development is often unpredictable and subject to delays.

To our knowledge, Li-Metal batteries have never been successfully used in automobiles. Li-Metal batteries have been successfully used for other applications, but their use in other vehicles, including eVTOLs, has been limited thus far. We are still in the development stages for our Li-Metal batteries and face significant scientific challenges that will need to be solved prior to commercializing our Li-Metal batteries for use in EVs and other applications such as eVTOLs. If we are not able to overcome these challenges, our Li-Metal batteries may not be able to be commercialized and our business may fail.

11

Table of Contents

In particular, we need to build Li-Metal battery cells which meet OEM requirements for use in EVs. While we have been making progress toward these requirements, significant engineering and mechanical barriers remain which must be solved before our Li-Metal batteries will meet OEM requirements. It is difficult to predict with certainty the pace of scientific development which will allow us to solve these challenges, and delays in meeting these challenges, or the introduction of new, unforeseen challenges, could impact the timing of the commercialization of our Li-Metal batteries, or our ability to reach commercialization at all.

We have a history of no revenues and of net losses, and expect to continue to incur losses for the foreseeable future. While we expect to become profitable eventually, our projections are based on internal assumptions that may prove incorrect, and we may never achieve or maintain profitability.

We incurred net losses of approximately $51.0 million, $31.3 million, and $13.9 million for the years ended December 31, 2022, 2021 and 2020, and had an accumulated deficit of approximately $145.3 million and $94.3 million from our inception through December 31, 2022 and 2021, respectively. As discussed in “Business - Our Technology,” to date, we have only validated the capabilities of our Li-Metal battery cell technology and have not produced Li-Metal batteries for sale. As a result, we have yet to generate any revenue from our business operations, and since inception, we have not achieved profitable operations or positive cash flows from our operations.

Our plan is to achieve the development and initial production of B-Sample batteries in 2023 and C-Sample batteries in 2024, which we expect to enable us to commence commercial production of our technology in 2025. For more information, see “Business—Our Growth Strategy.” As a result, we believe that we will continue to incur operating and net losses each quarter until at least 2026, the year following the one in which we expect to begin generating revenue as part of the commercialization of our Li-Metal battery technology. This plan and the related revenue and other financial projections reflect current estimates of future performance, based on certain financial and operational assumptions. Given our limited operating history, there can be no assurance that the actual results will be in line with our expectations. As discussed in other risk factors in this section, factors that could impact the timing and levels of our profitability include, but are not limited to: our ability to solve the scientific engineering and mechanical challenges to commercialize our products; the level of demand for our products; the performance of our products; the projected supply materials for our products; a reduction in the cost of Li-ion; average selling prices of EVs and our products; projected production capacities of our facilities; our collaboration with OEMs; the projected gross margin achievable upon sale of our products; and the extent to which growth of EV markets and continued shift in consumer preference will conform with projections.

Additionally, we expect the rate at which we will incur losses to 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 batteries, including any significant unplanned or accelerated expenses and new strategic investments to expand our research and development activities in science, engingeering, and technician personnel; invest in manufacturing capabilities; build up inventories of components for our batteries; invest in supply chain; increase our 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, thus affecting the value of your investment.

We will need substantial additional capital in the future to fund our business, and may be unable to meet our future capital requirements, impairing our financial position and results of operations.

The development, design, manufacture and sale of batteries is a capital-intensive business. We expect to sustain substantial operating expenses, without generating sufficient revenues to cover expenditures, for a number of years. To date, we have funded our operations through a combination of proceeds from the Business Combination and PIPE Financing and funding received through the sales of our redeemable convertible preferred stock. These funds are expected to finance our principal sources of liquidity and ongoing costs, such as research and development relating to our Li-Metal batteries and the construction of additional manufacturing facilities. In the future, if we are not able to fund our operations from cash flows generated from anticipated product sales, we expect that we will need to raise additional funds through a variety of possible methods, including, but not limited to, entry into joint ventures or other strategic arrangements, issuance of equity, equity-related or debt securities or through obtaining credit from financial institutions, as well as anticipated future revenue from product sales.

We believe that our cash on hand and marketable securities will be sufficient to meet our working capital and capital expenditure requirements for a period of at least 12 months from the date of this Report, and also sufficient to fund us to commercialization. However, additional funding may be required for a variety of reasons, including opportunities to build an integrated supply chain in the United States and delays in expected development of our Li-Metal battery cells. Our ability to successfully develop our products, commence commercial

12

Table of Contents

operations and expand our business will depend on many factors, including our working capital needs, the availability of equity and/or debt financing and, over time, our ability to generate positive cash flows from operations.

We cannot be certain that additional capital will be available on attractive terms, if at all, when needed, which could be dilutive to stockholders. We may be forced to decrease our level of investment in product development or scale back our operations, which could have an adverse impact on our business and financial prospects. Furthermore, the cost of debt could be higher than anticipated, which could negatively affect our earnings.

Our Li-Metal technology is untested in actual EVs, and may ultimately prove unworkable.

The results of third-party tests show that our multi-layer cells meet or exceed the preliminary OEM target requirements for energy density, low temperature discharge, room temperature fast charge and discharge, cycle life and safety. Additionally, Li-Metal is widely considered and accepted as the EV battery technology capable of achieving the highest energy density. However, we have not produced Li-Metal batteries for use by an actual EV, and no one has successfully demonstrated use of high energy density Li-Metal batteries in EVs. Our Li-Metal battery cell technology may prove unworkable when used in actual EVs, which would substantially undercut our business, operating results, financial condition and prospects, and could effectively eliminate the value of your investment.

If our batteries fail to perform as expected, our ability to develop, market and sell our batteries could be harmed.

Once commercial production of our Li-Metal battery technology commences, our batteries may contain defects in design and manufacture that may cause them to not perform as expected or that may require repairs, recalls, and design changes. Our battery cells are inherently complex and incorporate technology and components that have not been used for other applications and that may contain defects and errors, particularly when first introduced. For more information, see “Business—Our Technology.” Due to our limited operating history, we have a restricted frame of reference from which to evaluate the long-term performance of our Li-Metal batteries. There can be no assurance that we will be able to detect and fix any defects in our batteries prior to the sale to potential consumers. If our batteries fail to perform as expected, customers may delay deliveries, terminate further orders or initiate product recalls, each of which could adversely affect our sales and brand and could adversely affect our business, financial condition, operating results and prospects.

We are unable to predict user behavior when driving EVs with Li-Metal technology.

While conventional Li-ion battery technology has been tested in many applications for several decades, Li-Metal batteries have yet to be commercialized for use in EVs. Even if we work with OEMs to thoroughly test Li-Metal cells using pre-determined conditions, there is no guarantee that users in the field will not drive outside of recommended driving conditions and unintentionally abuse the batteries. In such events, performance and safety may be compromised, thus having a materially negative impact on our business, financial condition, operating results and prospects.

Delays in the pre-manufacturing development of our battery cells could adversely affect our business and prospects.

We have entered into JDAs with GM, Hyundai and Honda to jointly develop A-Sample Li-Metal batteries, with the expectation that such development will culminate in the widespread use of our technology in future EVs with these major OEMs, and eventually with other large OEMs. For more information, see “Business—Our Partnerships.” However, as we are still in the developmental stages with each of GM, Hyundai and Honda, we do not currently have existing arrangements to produce our Li-Metal cells for their vehicles, and production-ready models of our batteries will not be available until sufficiently tested and approved for inclusion in future OEMs’ EVs. Each time we produce a battery with a higher output, the product must undergo extensive pre-manufacturing development and testing. Anything that delays the consistent development and testing of pre-manufacturing battery cells samples at increasingly higher outputs, such as technology or engineering issues, could alter our prospects and adversely affect our business.

We may not be able to engage target OEM customers successfully and to convert such contacts into meaningful orders in the future.

Our success, and our ability to increase revenue and operate profitably, depends in part on our ability to identify OEM target customers and convert such contacts into meaningful orders or expand on current customer relationships. In some cases, our battery cells may be delivered to certain customers on a sampling basis, where they have the ability to evaluate whether our products meet their performance requirements before committing to joint development and meaningful orders. Our ongoing success depends on whether our target customers are willing to begin and continue using our battery technology, as well as whether their product lines continue to incorporate our products. Thus, our efforts to expand our manufacturing and sales to GM, Hyundai and Honda (with whom we have JDAs) or to other OEMs may not be

13

Table of Contents

successful, and may never result in products that achieve market acceptance, create additional revenue or become profitable, thus harming our financial results and prospects.

Our research and development efforts strive to create products that are on the cutting edge of technology and meeting the evolving requirements of our customers, but competition in our industry is high. To secure acceptance of our products, we must also constantly develop and introduce cost-effective, increasingly more scalable Li-Metal batteries with enhanced functionality and performance to meet evolving industry standards. If we are unable to retain target customers, or convert early trial deployments into meaningful orders, our business, financial condition, operating results and prospects could be materially adversely affected. In addition, we may not receive adequate assistance from OEMs to commercialize our products successfully, which could impair our results of operations.

If we are unable to integrate our products into EVs manufactured by OEM customers, our results of operations could be impaired.

Our batteries will be composed of modules assembled from battery cells, which we produce and intend to manufacture at scale. OEMs often require unique configurations or custom designs for batteries for their EVs. Once we enter into contracts with OEMs to produce batteries for their EVs, we expect to tailor the design of our batteries specifically to the EVs that these OEM customers manufacture. This development process requires not only substantial lead time between the commencement of design efforts for customized batteries and the commencement of volume shipments of the battery cells to the customer, but also the cooperation and assistance of the OEMs in order to determine the requirements for each specific application. Technical problems may arise that affect the acceptance of our product by the OEMs. If we are unable to design and develop products that meet the OEMs’ requirements, we may lose opportunities to obtain purchase orders, and our reputation and prospects may be damaged.

We may not be able to establish new, or maintain existing, supply relationships for necessary raw materials, components or equipment or may be required to pay costs for raw materials, components or equipment that are more expensive than anticipated, which could delay the introduction of our product and negatively impact our business.

Currently, we are in product development and our product design has yet to be finalized, so our volume demand is limited and we do not have long-term supply arrangements. As volume demand grows, we expect to negotiate long-term supply contracts. For our current product development needs, we source from third-party suppliers for raw materials, components and equipment necessary to develop and manufacture our Li-Metal battery cells. For more information, see “Business—Our Suppliers.”

To the extent that, when our volume demand so requires, if we are unable to enter into long-term agreements with our current or future suppliers on beneficial terms, or such suppliers experience difficulties ramping up their supply to meet our long-term requirements at reasonable cost, we may need to seek alternative sources for necessary raw materials, components or equipment necessary to develop and manufacture our Li-Metal battery cells, produce the raw materials or additional components in-house, or redesign our proposed products to accommodate available substitutes. To the extent that our suppliers experience any delays in providing or developing their products, we could also experience delays in delivering on our timelines.

Moreover, the price of raw materials, components and equipment could fluctuate significantly due to circumstances beyond our control. Substantial increases in prices would increase our operating costs and negatively impact our prospects. Any disruption in supply could also temporarily disrupt future research and development activities or production of our batteries until an alternative supplier is able to meet our requirements.

Changes in business conditions, unforeseen circumstances and governmental changes, as well as other factors beyond our control or which we do not presently anticipate, could affect our suppliers’ ability to deliver raw materials, components or equipment to us on a timely basis. For instance, we may be impacted by currency fluctuations, trade barriers, tariffs or shortages and other general economic or political conditions, such as the ongoing military conflict between Russia and Ukraine, which may limit our ability to obtain key raw materials or components for our Li-Metal batteries or significantly increase freight charges and other costs and expenses associated with our business. Any of the foregoing could materially and adversely affect our business, financial condition, operating results and prospects.

Our ability to manufacture our Li-Metal batteries at scale depends on our ability to build, operate and staff our facilities successfully.

We expect to expand our China and South Korea facilities in 2023 and to build additional facilities in the United States to meet the expected demand for our products. For more information, see “Business—Our Growth Strategy and —Our Facilities.” Because we expect to rely heavily on complex machinery, well-trained personnel and well-managed supply chain for our operations in these facilities, our production will involve a significant degree of uncertainty and risk in terms of operational performance and costs.

14

Table of Contents

Our manufacturing facilities are expected to consist of large-scale machinery combining many components. Such machinery will require us to make intensive capital expenditures prior to our ability to earn any revenues. The manufacturing facility machinery may suffer unexpected malfunctions from time to time and will depend on repairs and spare parts to resume operations, which may not be available when needed. Additionally, unexpected malfunctions of the manufacturing facility machinery may significantly affect the intended operational efficiency, thus materially and adversely affecting our business, financial condition and operating results.

The production of our facilities will also require us to hire and train highly-skilled personnel to operate such facilities, including engineers, workers, and indirect laborers. Recruiting and training such skilled staff will take significant cost and time, and an inability to do so timely or at all will inhibit the successful operation of these facilities, thus negatively affecting our business. In addition, the manufacturing of our Li-Metal batteries at facilities will require us to obtain various production licenses and permits, receive the necessary internal approvals from our customers regarding specifications and enter into agreements for the supply of raw materials, components and manufacturing tools and supplies. If we do not complete such steps timely, our manufacturing timeline or output could be significantly delayed or inhibited.

Finally, the production of our Li-Metal batteries at scale and competitive cost, compared to conventional Li-ion cells, will require us to achieve rates of throughput, use of electricity and consumables, yield, and rate of automation demonstrated for mature batteries and battery material. As we have not produced Li-Metal batteries at scale, our ability to achieve such rates is untested and subject to significant constraints and uncertainties. Operational performance and costs can be difficult to predict and are often influenced by factors outside of our control, such as, but not limited to, environmental hazards and remediation, costs associated with commissioning of machines, damages or defects in electronic systems, industrial accidents, fire and seismic activity and natural disasters, and problems with equipment vendors. Should operational risks materialize, they may result in lower yield, which would negatively affect our revenue growth and profitability as projected. Additionally, they could cause personal injury to or death of workers, the loss of manufacturing equipment, damage to manufacturing facilities, monetary losses, delays and unanticipated fluctuations in production, environmental damage, administrative fines, increased insurance costs and potential legal liabilities, all of which could have a material adverse effect on our business, financial condition, operating results and prospects.

We have pursued and may continue to pursue JDAs and other strategic alliances, which could have an adverse impact on our business if they are unsuccessful.

We have entered into strategic alliances, and may in the future enter into additional strategic alliances. For example, as further discussed in “Business—Our Partnerships,” we have JDAs with GM, Hyundai and Honda. We expect to form other strategic joint ventures in the future to support our supply chain as well as the build out of manufacturing facilities aimed at the commercialization of our batteries.

While offering potential benefits, these current and future strategic alliances with battery manufacturers, OEMs and others could subject us to a number of risks, including risks associated with sharing proprietary information, non-performance by our partners and costs of establishing and maintaining new strategic alliances, any of which may materially and adversely affect our business. We may have limited ability to monitor or control the actions of our partners and, to the extent any of them suffers negative publicity or harm to their reputation from events relating to their business, we may also suffer negative publicity or harm to our reputation by virtue of our association with them. For example, if we rely on our partners’ manufacturing facilities, those operations would be outside of our control. We could experience delays if our partners do not meet agreed-upon timelines or experience capacity constraints, and in turn, we could lose customers and face reputational harm.

Further, there is risk of potential disputes with any partners with whom we collaborate, and we could be affected by adverse publicity related to our partners, whether or not such publicity is related to their collaboration with us. Our ability to build a premium brand successfully could also be adversely affected by perceptions about the quality of our partners’ products. In addition, because we rely on our partners and third parties to meet our quality standards, there can be no assurance that we will successfully maintain quality standards. Any of the foregoing could adversely affect our business, financial condition, operating results and prospects.

The EV battery market continues to evolve and is highly competitive, and certain other battery manufacturers have significantly greater resources than we do.

The EV battery market, like the EV market it services, is fast-growing, extremely competitive and driven by the innovation of both large incumbents and emerging entrants like SES. For more information, see “Business—Competition.” Li-ion battery 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

15

Table of Contents

enhance their resources and competitive positioning. In addition, Li-ion battery manufacturers may continue to reduce cost and expand supply of conventional batteries and therefore reduce the prospects for our business or negatively impact our ability to sell our products at a market-competitive price and yet with sufficient margins.

A number of development-stage companies are also seeking to develop new technologies for Li-Metal batteries. Potential new entrants are seeking to develop new technologies for cathodes, anodes, electrolytes and additives. Some of these companies have established relationships with OEMs and are in varying stages of development. Additionally, many OEMs are researching and investing in conventional Li-ion batteries and/or Li-Metal battery efforts and, in some cases, in battery development and production. Furthermore, other companies are developing alternative technologies such as advanced diesel, ethanol, fuel cells or compressed natural gas, as well as potential improvements in the fuel economy of the internal combustion engine. We expect competition in battery 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. Developments in alternative technologies or improvements in battery technology made by competitors may materially adversely affect the sales, pricing and gross margins of our batteries. If a competing technology is developed that has superior operational or price performance, our business will be harmed. Similarly, if we fail to accurately predict and ensure that our battery technology can address customers’ changing needs or emerging technological trends, or if our customers fail to achieve the benefits expected from our Li-Metal batteries, our business will be harmed.

We may not be able to estimate accurately the future supply and demand for our batteries, which could result in a variety of inefficiencies in our business and hinder our ability to generate revenue. If we fail to predict accurately 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 batteries or our ability to develop, manufacture, and deliver batteries, or our profitability in the future. If we overestimate our requirements, our suppliers may have excess inventory, which may 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 or potential liability for late delivery. In addition, lead times for raw materials, components and manufacturing equipment may vary significantly and depend on factors such as the specific supplier, contract terms and demand for each raw material, component or manufacturing equipment at a given time. Any of the foregoing could result in delays in the delivery of batteries to our potential customers, which would harm our business, financial condition, operating results and prospects.

Certain components of our batteries pose safety risks that may cause accidents. We may be subject to financial and reputational risks due to product recalls and product liability claims, and we could face substantial liabilities that exceed our resources.

Due to the high energy density inherent in lithium-based batteries, our batteries can pose certain safety risks, including the risk of fire. Our state-of-the-art software is designed to accurately monitor and predict most safety incidents. Nevertheless, accidents causing death or personal injury or property damage can occur, and no high energy density battery will ever be 100% safe. For example, with repeated charge and discharge cycles, Li-Metal anodes are known to develop needle-like mossy structures known as dendrites, which can penetrate the separator and short-circuit the battery cell. Although we incorporate safety procedures in the research, development, manufacture and transportation of batteries that are designed to minimize safety risks - for example, our Li-Metal battery technology is designed to change the morphology of dendrite formation - the manufacture or use of our products may still cause accidents. Any accident, whether occurring at the manufacturing facilities or from the use of our products, may result in significant production interruption, delays or claims for substantial damages caused by personal injuries or property damage.

Product liability claims, even those without merit or those that do not involve our products, could harm our business, financial condition, operating results and prospects. The automobile industry in particular experiences significant product liability claims, and we face inherent risk of exposure to claims in the event that our battery products do not perform or are claimed not to have performed as expected. As is true for other commercial vehicle suppliers, we expect in the future that our battery products will be installed on vehicles that will be involved in crashes resulting in death or personal injury. Additionally, product liability claims that affect our competitors may cause indirect adverse publicity for us and our products.

A successful product liability claim against us could require us to pay a substantial monetary award. We may not be able to cover any substantial monetary judgment against us. Moreover, a product liability claim against us or our competitors could generate substantial

16

Table of Contents

negative publicity about our products and business and could have a material adverse effect on our brand, business, prospects, financial condition and operating results.

We may incur significant costs based on the warranties we may supply in our products and services.

Battery manufacturers are expected to give warranties that are reflective of the warranties given by manufacturers to users of the end product (e.g., from an OEM to a buyer of a vehicle). With respect to our battery products, we expect to offer warranties against any defects due to product malfunction or workmanship. We expect to provide a reserve for these potential warranty expenses, which is based on an analysis of historical warranty issues. There will be no assurance that future warranty claims will be consistent with past history, and in the event we experience a significant increase in warranty claims, there is no assurance that our reserves will be sufficient. This could have a material adverse effect on our business, financial condition and operating results.

If we fail to effectively manage eventual growth, then our business, results of operations and financial condition could be adversely affected.

Our future success depends upon our ability to grow, and if we are unable to manage our growth effectively, we may incur unexpected expenses and be unable to meet our eventual customers’ requirements, all of which could materially adversely affect our business, financial condition, operating results and prospects. To manage our current and anticipated future growth effectively, we must continue to maintain and enhance our infrastructure, financial and accounting systems and controls. We must also attract, train and retain a significant number of scientists, engineers, sales and marketing personnel, customer support personnel, professional services personnel, technical personnel and management personnel, and the availability of such personnel may be constrained.

As we continue to grow, including from the integration of employees and businesses acquired in connection with future acquisitions, we may find it difficult to maintain important aspects of our corporate culture, which could negatively affect our profitability and our ability to retain and recruit qualified personnel who are essential for our future success. If we do not effectively manage our growth, we may not be able to execute on our growth plan, respond to competitive pressures, take advantage of market opportunities, satisfy customer requirements or manufacture high-quality products. Additionally, we may not be able to expand and upgrade our infrastructure to accommodate future growth.

Failure to effectively manage our growth could also lead us to over-invest or under-invest in development and operations; result in weaknesses in our infrastructure, systems or controls; give rise to operational mistakes, financial losses, loss of productivity or business opportunities; and result in loss of employees and reduced productivity of remaining employees. Our growth is expected to require significant capital expenditures, which may lower our earnings, and may divert financial resources from other projects such as the development of new products and services. If we are unable to manage our growth effectively, our expenses may increase more than expected, our revenue may not increase or may grow more slowly than expected and we may be unable to implement our business strategy.

Our business depends substantially on the continuing efforts of our senior executives and other key personnel as well as the ability to attract, train and retain highly skilled employees and key personnel.

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. As we build our brand and become better known, there is increased risk that competitors or other companies will seek to hire our personnel. All of our executives and engineering staff are subject to non-competition agreements, but we may face challenges in enforcing these non-competition agreements, and such agreements may become illegal if the Federal Trade Commission’s proposed Non-Compete Clause Rule is implemented. The failure to attract, integrate, train, motivate and retain these personnel could seriously harm our business and prospects.

To execute our business plan, we must attract and retain highly qualified personnel in research and development, sales and marketing, production and other leadership roles. Competition for these employees is intense, and we may not be successful in attracting and retaining qualified personnel. We have from time to time in the past experienced, and we expect to continue to experience, difficulty in hiring and retaining highly skilled employees with appropriate qualifications in relevant industries. Many of the companies with which we compete for experienced personnel have greater resources than we have. In addition, in making employment decisions, particularly in high-technology industries, job candidates often consider the value of the equity they are to receive in connection with their employment. Employees may be more likely to leave us if the shares they own or the shares underlying their equity incentive awards have significantly appreciated or significantly reduced in value. A significant talent pool consists of nationals from countries that may require a license from the United States Bureau of Industry and Security to work with our technology, which raises the cost of hiring due to the uncertainty that a

17

Table of Contents

license may not be granted and the candidate would be unemployable in the role envisioned. If we fail to attract new personnel, or fail to retain and motivate our current personnel, our business and growth prospects could be harmed.

In addition, we are highly dependent on the services of Dr. Qichao Hu, our Founder and Chief Executive Officer, and other senior technical and management personnel, including our executive officers, who may take significant amounts of time to replace. If Dr. Hu or other key personnel were to depart, we may not be able to successfully attract and retain senior leadership necessary to grow our business.

If we do not maintain and continue to develop our corporate culture as we grow and evolve, it could also harm our ability to foster the innovation, creativity and teamwork we believe that we need to support our growth. Additions of executive-level management, significant numbers of new employees, our workforce reduction and higher employee turnover could significantly and adversely impact our culture.

The uncertainty in global economic conditions and the risks relating to health epidemics, including the COVID-19 pandemic, could have a material adverse effect on our business and results of operations. Our ability to operate in any respect may be interrupted by the current COVID-19 pandemic.

We face various risks relating to public health issues, including epidemics, pandemics, and other outbreaks, including the ongoing COVID-19 pandemic. The effects and potential effects of COVID-19 include, but are not limited to, its impact on general economic conditions, trade and financing markets and changes in customer behavior, and significant uncertainty in the overall continuity in business operations. COVID-19 has also disrupted the manufacturing, delivery and overall supply chain of EV manufacturers and suppliers and EV batteries. In particular, COVID-19 may cause an increase in costs resulting from the efforts of manufacturers of EVs or EV batteries to mitigate the effects of COVID-19 and delays in EV manufacturers’ schedules to full commercial production of EVs and disruptions to these supply chains, among other negative effects.

Following the re-opening of non-essential businesses and the easing of restrictions on non-essential in-person work, we have ramped up research and development hiring and increased our investment in in-person work. However, measures that have been relaxed may be reimplemented if COVID-19 continues to spread. If, as a result of these measures, we have to limit the number of employees and contractors at any research and development or manufacturing facility at a given time, it could cause a delay in our development, testing and manufacturing efforts and a delay in our product schedule. For example, previous spikes in COVID-19 cases in Shanghai resulted in a government mandated temporary shutdown of our Shanghai facility in April 2022, causing a delay of over a month in our development, testing and manufacturing efforts, our product schedule and our ability to obtain materials from our suppliers in the affected area. The government-mandated shutdown was lifted on June 1, 2022 and the Shanghai facility has re-opened. There can be no assurances that other temporary shutdowns will not be imposed in the future. If our workforce is unable to work effectively, or if we are required to shut down our facilities on a more permanent basis, including due to illness, quarantines, government actions or other restrictions in connection with COVID-19, our operations will be adversely affected.

We continue to monitor closely the impact of COVID-19 on all aspects of our business and geographies, including its impact on our employees, suppliers, business partners and potential distribution channels and customers. The extent to which the COVID-19 pandemic may continue to affect our business will depend on continued developments, such as the emergence of new variants and status of governmental measures to combat it, which are uncertain and cannot be predicted. Even after the COVID-19 pandemic has subsided, we may continue to suffer an adverse effect on our business due to possible longer-term global economic effects of COVID-19, including any economic recession. If the immediate or prolonged effects of the COVID-19 pandemic have a significant adverse impact on government finances, it would create uncertainty as to the continuing availability of incentives related to EV purchases and other governmental support programs. In addition, a recurrence of COVID-19 cases or an emergence of additional variants or strains could cause other widespread or more severe impacts depending on where infection rates are highest.

Risks Relating to the EV Industry

Our future growth and success depend on the willingness of vehicle operators and consumers to adopt EVs.

Our growth is highly dependent upon the adoption of EVs by commercial vehicle and specialty vehicle operators and consumers. If the markets for EVs do not develop as we expect or develop more slowly than we expect, our business, prospects, financial condition and operating results will be harmed, because demand for our products and services will not increase as expected or may even be reduced. The market for alternative fuel vehicles is relatively new, rapidly evolving, characterized by rapidly changing technologies, price competition, numerous competitors, evolving government regulation and industry standards, frequent new vehicle announcements and changing consumer demands and behaviors.

18

Table of Contents

Other factors may influence the adoption of EVs, including, but not limited to:

Any of these factors could impair the development of the EV market, lowering demand. In anticipation of an expected increase in the demand for EVs in the next few years, we plan to develop, test, manufacture and commercialize our Li-Metal battery technology. However, the markets we expect to target, primarily those in North America, Europe and Asia, may not achieve the level of growth we expect. If any market fails to achieve our expected level of growth, we may have excess manufacturing capacity and may not be able to generate enough revenue to achieve or sustain our profitability.

Developments in alternative technology or other fossil fuel alternatives may adversely affect the demand for our battery products.

Significant developments in alternative technologies, such as fuel cell technology, advanced diesel, ethanol or natural gas, or breathing batteries, may materially and adversely affect our business, financial condition, operating results and prospects in ways that we may not currently anticipate. Existing and other battery technologies, fuels or sources of energy may emerge as customers’ preferred alternatives to our battery products. Any failure by us to develop new or enhanced technologies or processes, or to react to changes in existing technologies, could materially delay our development and introduction of new and enhanced alternative products, which could result in decreased revenue and a loss of market share to our competitors.

Our research and development efforts may not be sufficient to adapt to changes in alternative fuel and EV technology. As technologies evolve, we plan to upgrade or adapt our energy solutions with the latest technology, in particular lighter weight modules and packs, advanced cooling methods, more sophisticated safety management software, more efficient manufacturing process, and advanced battery chemistry, which may also negatively impact the adoption of our other products. However, we may not compete effectively with alternative systems if we are not able to develop, source and integrate the latest technology into our battery products.

If the EVs in which our batteries are installed do not meet certain motor vehicle standards, our business, operating results and prospects could be adversely affected.

Our products are expected to be used as components in EVs. All vehicles sold must comply with applicable international, federal, and state motor vehicle safety standards, which vary by national and other jurisdictions. In the United States, vehicles that meet or exceed all federally mandated safety standards are certified under the federal regulations. Rigorous testing and the use of approved materials and equipment are among the requirements for achieving federal certification. Failure by our eventual EV manufacturing customers to satisfy motor vehicle standards could have a material adverse effect on our business and operating results.

Moreover, we may incur our own significant costs in complying with these regulations. Laws and regulations related to the EV industry and alternative energy are currently evolving and we face risks associated with changes to these laws and regulations.

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

Internationally, there may be laws and regulations in jurisdictions we have not yet entered or laws of which we are unaware in jurisdictions we have entered that may restrict our sales or other business practices. Even for those jurisdictions we have analyzed, the laws and regulations in this area can be complex, difficult to interpret and may change over time. Continued regulatory limitations and other obstacles interfering with our or our eventual customers’ ability to sell products could have a negative and material impact on our business, financial condition, operating results and prospects.

Our ability to successfully market our products will depend on the establishment of charging station networks meeting the needs of EVs using our products. If any of the charging station networks are not compatible with such products and technologies, our sales could be adversely affected.

We design, develop, and manufacture electric power batteries for EVs. However, we do not manufacture chargers or charging poles that are necessary for using our products. In addition, we will rely on third parties, such as city governments, utility providers and private investors, to build charging stations for EVs using our products. If no charging station networks are built in markets in which OEMs using our products target their EVs, there would be little demand for electric battery products in those areas.

Further, existing charging station networks have not been established under a uniform standard and it could diminish our sales if any of the networks are not compatible with EVs using our products and technologies. In order for our fast-charging batteries to become widely adopted in electric passenger cars, a critical mass of compatible fast-charging stations must be installed and in operation in any given urban area where our OEM customers plan to enter. Establishing a network of fast-charging stations requires significant capital investment and government approvals. It also requires government regulators to believe that the merits of fast-charging stations support the costs of such construction. If a sufficient number of charging stations that accommodate EVs using our products and technologies cannot be built up and be functional in a timely manner, it will be difficult for us to retain our existing customers and to attract new customers. As a result, our business, financial condition, operating results and prospects may be materially and adversely affected.

If emerging standards in charging station networks are not compatible with our current products or in development products and technologies, we may miss market opportunities and our financial performance will suffer. If other EV battery companies’ products and services, including industry-standard technologies or other new standards, emerge or become dominant in any of these areas, or differing standards emerge in global markets, demand for our technology and products could diminish. As standards emerge, such as those in China including specifications for hardware, connecting equipment and service networks, and standards for communication and inspection, compatibility of prior fast-charging stations could be made obsolete.

The Biden Administration has put forth ambitious goals for advancing new battery technology, which may lead to a shortage of the metals required for manufacturing batteries.

The Biden Administration has put forth ambitious goals for investing in “clean energy,” including goals to replace gasoline-operated vehicles with EVs, and recently signed into law the Inflation Reduction Act of 2022, which includes multiple incentives to promote clean energy, electric vehicles, battery and energy storage manufacture or purchase. In order to meet these ambitious goals, a secure supply chain of raw materials, including lithium, copper and nickel, will need to be obtained. Developing mines for these materials can take a significant

amount of time. If production of battery technology increases faster than this supply chain can be secured, it may lead to a shortage of these raw materials, which could negatively affect our business.

Risks Relating to Our Intellectual Property

Our patent applications may not result in issued patents or our patent rights may be challenged, invalidated or limited in scope, any of which could have a material adverse effect on our ability to prevent others from competing or interfering with the commercialization of our products.

Our key technological innovations, including innovations that are currently commercialized in our products and innovations that we plan to deploy in the future, are described in our issued patents and pending patent applications, as well as patent applications that we plan to file in the future. For more information, see “Business—Intellectual Property.” The process of applying for and obtaining a patent is expensive, time consuming and does not always result in patent claims as expected or needed. We may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost, in a timely manner, or in all jurisdictions where protection may be commercially advantageous, or we financially may not be able to protect our proprietary rights at all. There is also no assurance that the pending applications will result in issued patents.

In addition, the issuance of a patent does not give us the right to practice the patented invention. Third parties may have blocking patents that could prevent us from marketing our products and practicing our technology. Alternatively, third parties may seek to market their products similar to or otherwise competitive with our products. In these circumstances, we may need to defend and/or assert our patents, including by filing lawsuits alleging patent infringement. In any of these types of proceedings, a court or agency with jurisdiction may find our patents invalid and/or unenforceable. Even if we have valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business objectives. Under the terms of our JDAs, and as part of our sponsored research projects with universities, we may file patent applications with third parties and end up co-owning certain of our patents.  Co-ownership of a patent may require us to enter into license agreements with third parties, which are less favorable than if we were the sole owner of the patent. Furthermore, if the other owners are unwilling to join us in an enforcement action, we may be unable to enforce our jointly owned patent rights against infringers. Such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. If one or more of our patents are held to be invalid or unenforceable, or if claims of those patents are interpreted narrowly, or if patents fail to issue from our pending applications, our competitiveness and value may also be undermined. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.

We rely heavily on our intellectual property portfolio, including unpatented proprietary technology. If we are unable to protect our intellectual property rights from unauthorized use, our business and competitive position would be harmed.

We may not be able to prevent unauthorized use of our intellectual property, which could harm our business and competitive position. We rely upon a combination of the intellectual property protections afforded by patent, 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 in our proprietary technologies.

We also rely substantially on unpatented proprietary technology, including know-how or trade secrets. We seek to protect our intellectual property rights in various ways, including through nondisclosure and invention assignment agreements with our employees and consultants and through non-disclosure agreements with business partners and other third parties. We cannot ensure that these agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation, or disclosure of such trade secrets, know-how or other proprietary information. There can be no assurance that employees, consultants, vendors and customers have executed such agreements or have not breached or will not breach their agreements with us, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known or independently developed by competitors. The theft or unauthorized use or publication of our trade secrets and other confidential business information could reduce the differentiation of our products and harm our business, the value of our investment in development or business acquisitions could be reduced and third parties might make claims against us related to losses of their confidential or proprietary information. Any of the foregoing could materially and adversely affect our business.

Additionally, despite our efforts to protect our proprietary rights, third parties may attempt to copy or otherwise obtain and use our intellectual property. 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 be time-consuming and expensive and could divert management’s attention, which could harm our business, results of operations and financial condition. In

21

addition, existing intellectual property laws and contractual remedies may afford less protection than needed to safeguard our intellectual property portfolio.

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 or sell our products, which could make it more difficult for us to operate our business. From time to time, we may receive claims or inquiries from holders of patents or trademarks claiming that and/or inquiring whether we are infringing their proprietary rights and/or seeking court declarations that they do not infringe upon our intellectual property rights. Companies holding patents or other intellectual property rights relating to batteries, electric motors or electronic power management systems 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:

In the event of a successful claim of infringement against us and our failure or inability to obtain a license to the infringed technology, our business, prospects, operating results and financial condition could be materially adversely affected. In addition, any litigation or claims, whether or not valid, could result in substantial costs and diversion of resources and management’s attention.

We may face risks relating to protecting our intellectual property in various countries.

Patent, trademark and trade secret laws vary significantly throughout the world. Filing, prosecuting, and defending patents in all countries throughout the world would be prohibitively expensive, and the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection or licenses but enforcement is not as strong as that in the United States.

A number of foreign countries do not protect intellectual property rights to the same extent as do the laws of 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 more expensive and difficult outside of the United States. Some courts inside and outside the United States may be less willing or unwilling to protect trade secrets and agreement terms that address non-competition are difficult to enforce in many jurisdictions and might not be enforceable in certain cases. Failure to adequately protect our 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 and a decrease in our revenue, which would adversely affect our business, financial condition, operating results and prospects.

Risks Relating to our International Operations

The international nature of our business exposes us to business, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.

While we are incorporated as a Delaware corporation, we have significant operations outside the United States. Battery manufacturing is capital intensive, and to reduce dilution and financial burden, SES has been applying for appropriate government financial support. We currently have an operating facility in Shanghai, China, focused on supply chain development, manufacturing process development, battery cell development and production, AI software, BMS and module development, and an operating facility in Chungju, South Korea, focused on manufacturing process development and battery cell product development. We have received financial support from the Government of South Korea to partially offset the expense of facility construction and plan to seek additional government financial support to the extent possible. Also, due to geopolitical considerations, we may be required to introduce certain commercial inefficiencies into our operations.

22

Table of Contents

We are subject to, and could become further subject to, various legal, political, regulatory and social requirements and economic conditions both inside and outside the United States. Expansion into new markets requires significant resources and management’s attention, as well as significant expenditures, including for the establishment of local operating entities, hiring of local employees and establishment of facilities in advance of generating any revenue. Some of the risks associated with international operations in China, South Korea and/or other countries, such as in the development, manufacturing, marketing or sale of our products, include, but are not limited to:

Our ability to deal with these issues could be affected by existing or new U.S. laws and the need to protect our intellectual property and assets. The materialization of any such risks could have an adverse impact on our business, financial condition, operating results and prospects.

23

Table of Contents

We could experience losses associated with our intellectual property in relation to our operations in China.

We rely upon the fair interpretation and enforcement of patent, copyright, trademark and trade secret laws in the U.S., similar laws in other countries, and agreements with employees, customers, suppliers, licensors and other parties. Such reliance serves to establish and maintain the intellectual property rights associated with the technology that we develop and ultimately sell. However, the laws and courts of certain countries at times do not protect intellectual property rights or respect contractual agreements to the same extent as the laws of the U.S. Therefore, in certain jurisdictions we may not be able to protect our intellectual property rights against counterfeiting or enforce our contractual agreements with other parties. Specifically, as discussed above, the Company conducts research and development operations in China. Article VII of the National Intelligence Law of China requires every commercial entity in China, by simple order of the Chinese government, to act as an agent of the government by committing espionage, technology theft, or whatever else the government deems to be in the national interest of China. If the Chinese government were to require the appropriation of certain of our intellectual property in the national interest, this could lead to material adverse effects on our operations and competitive positions.

Implementation of labor laws and regulations in China may adversely affect our business and results of operations.

Pursuant to the labor contract law of China that took effect in January 2008, its implementation rules that took effect in September 2008 and its amendment that took effect in July 2013, employers are subject to stricter requirements in terms of signing labor contracts, minimum wages, paying remuneration, determining the term of employees’ probation and unilaterally terminating labor contracts. Due to lack of detailed interpretative rules and uniform implementation practices and broad discretion of the local competent authorities, it is uncertain as to how the labor contract law and its implementation rules will affect our current employment policies and practices. Our employment policies and practices may violate the labor contract law or its implementation rules, and we may thus be subject to related penalties, fines or legal fees. Compliance with the labor contract law and its implementation rules may increase our operating expenses, in particular our personnel expenses. In the event that we decide to terminate some of our employees or otherwise change our employment or labor practices, the labor contract law and its implementation rules may also limit our ability to effect those changes in a desirable or cost-effective manner, which could adversely affect our business and results of operations.

As the interpretation and implementation of these laws and regulations are still evolving, we cannot assure you that our employment practice will at all times be deemed in full compliance with labor-related laws and regulations in China, which may subject us to labor disputes or government investigations. If we are deemed to have violated relevant labor laws and regulations, we could be required to provide additional compensation to our employees and our business, financial condition and results of operations could be adversely affected.

Further, labor disputes, work stoppages or slowdowns at our operations facilities or any of our third-party service providers could significantly disrupt daily operation or our battery development plans and have materially adverse effects on our business.

The unavailability, reduction or elimination of, or uncertainty regarding, government and economic incentives or subsidies available to us, end-users or OEMs could have a material adverse effect on our business, financial condition, operating results and prospects.

In 2019, in connection with our establishment of our Shanghai facility, the first two years of rent on the facility totaling approximately RMB7.1 million was borne by the Jiading district local government which also took on certain renovations to the facility at the cost of approximately RMB 4.3 million such that it is suitable for our use. In 2020, we received an incentive award of RMB10,000 under the Jiading Industrial Zone Development Potential Award from the Jiading district local government. In 2022, we also received an incentive award from certain South Korean government agencies. We intend to apply for further grants in the future in the jurisdictions in which we operate. Government incentives and subsidies are granted in connection with government’s efforts to promote the development of the local economy and other policies. Some local government incentives and subsidies may be challenged by higher-level government authorities. Therefore, government incentives and subsidies may be modified, terminated or subject to clawback at the sole discretion of the relevant governmental authorities. Additionally, because laws, regulations and policies with respect to incentives and subsidies may change, we cannot be sure that government incentives and subsidies will continue to be available. In the event that we cease to receive any government incentives or subsidies, any current or future incentive or subsidy is reduced, or any of our current or future incentives or subsidies are challenged, our business, financial condition and operating results may be adversely affected. See Note 10 “Government Grant” of the Notes to the Financial Statements for discussion of our accounting for government incentives.

Additionally, we believe that, currently, the availability of government incentives and subsidies available to end-users and OEMs is an important factor considered by customers when purchasing EVs, and that growth in the battery market will depend in part on the availability and amounts of these subsidies and incentives for EVs. Any further reduction or elimination of government and economic incentives or subsidies may result in the diminished competitiveness of the alternative fuel vehicle industry generally or EVs that use our batteries in particular.

24

Table of Contents

Currently, government programs, including in China and Europe, favor the purchase of EVs, including through disincentives that discourage the use of gasoline-powered vehicles. In the United States, the Inflation Reduction Act of 2022 provides tax credits for the purchase of electric vehicles, and the states of California, Massachusetts, Oregon and Washington have recently banned the sale of new gas-powered vehicles by 2035, and other states may follow. If such government laws or programs are reduced or eliminated, or the available benefits thereunder are exhausted earlier than anticipated, demand for EVs may decrease and our anticipated sales of EV battery products could be adversely affected. In addition, OEM customers may delay taking delivery of our battery products if they believe that certain EV incentives will be available at a later date, which may adversely affect our business, financial condition, operating results and prospects.

Our incentives from various governments are conditional upon achieving or maintaining certain performance obligations and are subject to reduction, termination, or clawback.

We have received, and may in the future continue to receive, benefits and incentives from national, state, and local governments in various regions of the world designed to encourage us to establish, maintain, or increase investment, workforce, or production in those regions. These incentives may take various forms, including grants, loan subsidies, and tax arrangements, and typically require us to achieve or maintain certain levels of investment, capital spending, employment, technology deployment, or research and development activities to qualify for such incentives or could restrict us from undertaking certain activities. We may be unable to obtain significant future incentives to continue to fund a portion of our capital expenditures and operating costs, without which our cost structure would be adversely impacted. We also cannot guarantee that we will successfully achieve performance obligations required to qualify for these incentives or that the granting agencies will provide such funding. These incentive arrangements typically provide the granting agencies with rights to audit our compliance with their terms and obligations. Such audits could result in modifications to, or termination of, the applicable incentive program. The incentives we receive could be subject to reduction, termination, or clawback, and any decrease or clawback of government incentives could have a material adverse effect on our business, results of operations, or financial condition.

Risks Relating to Regulations and Our Compliance With Such Regulations

Our operations expose us to litigation, environmental and other legal compliance risks. Compliance with laws and regulations can be expensive, and our failure to comply with these laws and regulations may result in monetary damages and fines, adverse publicity and a material adverse effect on our business.

We are subject to a variety of litigation, environmental, health and safety and other legal compliance risks. These risks include, among other things, possible liability relating to product liability matters, personal injuries, intellectual property rights, contract-related claims, health and safety liabilities, environmental matters and compliance with U.S. and foreign laws, competition laws and laws governing improper business practices.

Our operations in the United States, China, and South Korea may be subject environmental laws and regulations, including laws and regulations relating to water, discharges, emissions, chemicals, hazardous materials, natural resources, remediation and contamination. Compliance with these laws can be difficult and costly. For example, battery life cycle management regulations and regulations governing the transport of batteries may impose substantial requirements on our operations in the United States. Our operations may be required to obtain and comply with environmental permits, many of which may be difficult and expensive to obtain and must be renewed on a periodic basis. A failure to comply with these laws, regulations or permits could result in substantial liabilities, including fines, penalties, the suspension or loss of permits, and possibly orders to cease the non-compliant operations.

As a business with international reach, we are subject to complex laws and regulations in jurisdictions in which we operate. Those laws and regulations may be interpreted in different ways. They may also change from time to time, as may related interpretations and other guidance. Changes in laws or regulations could result in higher expenses and payments, and uncertainty relating to laws or regulations may also affect how we conduct our operations and structure our investments and could limit our ability to enforce our rights.

Changes in environmental and climate laws or regulations, including laws relating to greenhouse gas emissions, could lead to new or additional investment in manufacturing designs, subject us to additional costs and restrictions, including increased energy and raw materials costs, and could increase environmental compliance expenditures. We are subject to various environmental laws and regulations on air emission, waste water discharge, solid waste, noise and the disposal of hazardous materials. Cobalt and lithium are toxic materials that are important raw materials in our batteries. We also use, generate and discharge other toxic, volatile and hazardous chemicals and wastes in our research, development and manufacturing activities. Under Chinese, South Korean, and U.S. environmental regulations, we are required to maintain the pollutant emission levels at the facility within the levels prescribed by the relevant governmental authorities and obtain a pollution discharge permit for water and air emissions. In addition, certain laws and regulations require enterprises like us that generate

25

Table of Contents

hazardous wastes to engage companies which are licensed and qualified to process the hazardous wastes, and to collect, store, dispose of and transfer the hazardous waste.

If we fail to comply with national and local environmental protection laws and regulations, the relevant governmental authorities may impose fines or deadlines to cure instances of noncompliance, and may even order us to cease operations if we fail to comply with their requirements. In particular, any breach by us in connection with requirements relating to the handling of hazardous wastes may subject us to monetary damages and fines. In addition, if any third party suffers any loss as a result of our pollutant emission practices, our improper handling of hazardous wastes or our noncompliance with environmental regulations, such third parties may seek damages from us.

There can be no assurance that we will be able to comply with all environmental laws and regulations at all times as the environmental legal regime is evolving and becoming more stringent, especially in China, South Korea, and the United States. Therefore, if these or other governments where we do business impose more stringent regulations in the future, we will have to incur additional substantial costs and expenses in order to comply with new regulations, which may negatively affect our results of operations. If we fail to comply with any of the present or future environmental regulations in any material aspect or cause any loss to any third parties due to our pollutant emission practices, improper handling of hazardous wastes or other environmental noncompliance, we may suffer from negative publicity and may be required to pay substantial fines, pay damages to such third parties, or suspend or even cease operations Failure to comply with environmental laws and regulations may materially and adversely affect our business, financial condition, operating results and prospects.

Failure to comply with certain health and production safety laws and regulations governing hazardous materials could materially adversely affect our business and results of operations.

In the sourcing of our products throughout the world, we process, store, dispose of and otherwise use large amounts of hazardous materials. As a result, we are subject to extensive and evolving health and production safety laws and regulations governing, among other things: the health of our employees and safety production requirements regarding the generation, handling, storage, use and transportation of hazardous materials. Compliance with these laws and regulations results in ongoing costs. Failure to comply with these laws or regulations, or to obtain or comply with the relevant permits, could result in fines, criminal charges or other sanctions by regulators. Furthermore, we may be ordered to rectify a noncompliance within a stipulated deadline; and if we fail to do so, we may be ordered to cease operations. Our ongoing compliance with health and safety laws, regulations and permits could require us to incur significant expenses, limit our ability to modify or expand our facilities or continue manufacturing and make other capital improvements. In addition, private parties, including current or former employees, could bring personal injury or other claims against us due to the presence of, or exposure to, hazardous substances used, stored or disposed of by us or contained in our products.

We are subject to U.S. and foreign anti-corruption, anti-bribery, anti-money laundering, financial and economic sanctions and similar laws and regulations. We can face criminal liability and other serious consequences for violations, which can harm our business.

We are subject to anti-corruption, anti-bribery, anti-money laundering, financial and economic sanctions and similar laws and regulations in various jurisdictions in which we conduct or in the future may conduct activities, including the U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act 2010, and other anti-corruption laws and regulations in countries in which we conduct activities. Anti-corruption laws prohibit us and our officers, directors, employees, contractors and business partners acting on our behalf, including agents, from corruptly offering, promising, authorizing or providing, directly or indirectly, anything of value to a “foreign official” for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. 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. These laws also prohibit non-governmental “commercial” bribery and soliciting or accepting bribes. A violation of any of these laws or regulations could result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm and other consequences and adversely affect our business, financial condition, operating results and reputation. Our policies and procedures designed to ensure compliance with these laws and 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.

As we increase our international cross-border business and expand our operations abroad, we may continue to engage with business partners, suppliers and third-party intermediaries to market our services and to obtain necessary permits, licenses and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize such activities. There can be no assurance

26

Table of Contents

that our employees and agents will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible. As we increase our international business, our risks under these laws may increase.

Detecting, investigating and resolving actual or alleged violations of anti-corruption, anti-bribery, anti-money laundering or financial and economic sanctions laws can require a significant diversion of time, resources and attention from management. Non-compliance with these laws could subject us to whistleblower complaints, adverse media coverage, investigations, subpoenas received, enforcement actions, prosecution and severe fines, damages and administrative, civil and criminal sanctions, collateral consequences, remedial measures and legal expenses, all of which could materially and adversely affect our business, financial condition, operating results and reputation. In addition, changes in these laws in the future could adversely impact our business and investments in our securities.

Governmental trade controls, including export and import controls, sanctions, customs requirements and related regimes, could subject us to liability or loss of contracting privileges, limit our ability to transfer technology or compete in certain markets and affect our ability to hire qualified personnel.

Our technology and products, including components of our products, are subject to export control and import laws and regulations, including those by the U.S. Export Administration Regulations, U.S. Customs regulations, various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Control, and similar regulations by the South Korean government. These jurisdictions’ export control laws and regulations and economic sanctions prohibit the shipment of certain products, technologies and services to embargoed or sanctioned countries, governments and persons, as well as to various countries and persons due to national security and foreign policy concerns. In particular, U.S. and South Korean export control laws apply to cells with an energy density greater than 350 Wh/kg, and require a license for the export of technology and cells exceeding that threshold to many locations outside of each respective jurisdiction, including China and Singapore. Some of our technology and products are thus presently subject to these license requirements under export controls.

Complying with export control and sanctions regulations for a particular sale may be time-consuming and result in the delay or loss of sales opportunities. We have set up an export controls compliance program internally. If we fail to comply with these laws and regulations, we and even some of our employees could be subject to substantial civil and/or criminal penalties, including the possible loss of export or import privileges, fines, which may be imposed on us and responsible employees or managers and, in extreme cases, the incarceration of responsible employees or managers.

A significant talent pool is comprised of nationals from countries that may require a license from the Bureau of Industry and Security to work with our technology (such as China, India, Russia, South Korea, Taiwan and Japan), which raises the cost of hiring due to the uncertainty that a license may not be granted and the candidate would be unemployable in the role envisioned. In addition, changes in our products or solutions or changes in applicable export or import laws and regulations may create delays or prohibitions in the introduction and sale of our products and solutions in international markets, increase costs due to changes in import and export duties and taxes, prevent our customers from deploying our products and solutions or, in some cases, prevent the export or import of our products and solutions to certain countries, governments or persons altogether. Any change in export or import laws and regulations, shift in the enforcement or scope of existing laws and regulations, or change in the countries, governments, persons or technologies targeted by such laws and regulations, could also result in decreased use of our products and solutions, decreased ability to export or sell our products and solutions to customers, and decreased ability to import components or parts critical to the manufacture of our products. Any decreased use of our technology and products, limitation on our ability to export or sell our technology and products, or limitation on our ability to import raw materials, components or equipment would likely adversely affect our business, financial condition, operating results and prospects.

We have incurred and will continue to incur increased costs related to operating as a public company, especially now that we are no longer an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and our management will be required to devote substantial additional time to new compliance initiatives and corporate governance practices.

We have incurred and will continue to incur significant legal, accounting and other expenses that Old SES did not incur as a private company. We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Protection Act, as well as rules adopted, and to be adopted, by the SEC and the NYSE. Our management is required to certify financial and other information in our quarterly and annual reports, as well as to establish and evaluate periodically disclosure controls and procedures and internal control over financial reporting. Additionally, in light of our loss of “emerging growth company” status when we became a “large accelerated filer” as of December 31, 2022, we are subject to expanded  disclosure obligations regarding executive compensation in our periodic reports and proxy statements and the requirements to hold nonbinding advisory vote on executive compensation and stockholder

approval of any golden parachute payments not previously approved, and can no longer take advantage of an extended transition period for complying with new or revised accounting standards.

Our management and other personnel have devoted and will need to continue to devote a substantial amount of time to these compliance initiatives. Moreover, we expect these rules and regulations to continue to increase substantially our legal and financial compliance costs, especially now that we are no longer an “emerging growth company,” and to make certain activities more time-consuming and costly, which will increase our operating expenses. These rules and regulations applicable to public companies may make and have made it more difficult and more expensive for us to obtain director and officer liability insurance, and we will likely incur additional costs to maintain sufficient insurance coverage as a public company going forward.

This Annual Report is the first annual report in which we are required to include a management report on the effectiveness of the internal control over our financial reporting and obtain an attestation report from our independent registered public accounting firm on the effectiveness of our internal control over financial reporting. As later discussed in this Annual Report, our management and independent registered public accounting firm have concluded that we did not maintain effective internal control over financial reporting as of December 31, 2022. For more information on the risks associated with the compliance cost of remediating the material weaknesses in, and establishing and maintaining, effective internal control over financial reporting, as well as other related risks, see “—We have identified material weaknesses in our internal control over financial reporting, which could, if not effectively remediated, result in material misstatements in our financial statements, and a failure to meet our reporting and financial obligations.” If in the future, we are unable to record, process, summarize and report financial information accurately and within the time periods specified in the rules and forms of the SEC, our ability to meet these additional requirements in a timely manner will be adversely affected. This failure could negatively affect the market price and trading liquidity of our common stock, restrict our access to the capital markets, cause investors to lose confidence in our reported financial information, subject us to civil and criminal investigations and penalties, and generally materially and adversely impact our business and financial condition.

We have identified material weaknesses in our internal control over financial reporting, which could, if not effectively remediated, result in material misstatements in our financial statements, and a failure to meet our reporting and financial obligations.

​

Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and errors in our financial statements and operate successfully as a public company. As later discussed in this Annual Report, our management and independent registered public accounting firm have concluded that we did not maintain effective internal control over financial reporting as of December 31, 2022. We are actively engaged in developing and implementing a remediation plan designed to address these material weaknesses and are committed to remediating them as promptly as possible. For more information, see “Part II, Item 9A. Controls and Procedures.” However, we cannot be certain that all current material weaknesses in internal control will be remediated and our internal control over financial reporting considered effective going forward. Because of its inherent limitations, our system of internal control over financial reporting may not prevent or detect every misstatement.

If we are unable to remediate the existing material weaknesses in our internal controls of financial reporting and achieve effective internal control, or if we identify additional material weaknesses in our internal control over financial reporting, we may be unable to accurately report our financial results, or report them within the timeframes required by the SEC. If this occurs, we also could become subject to sanctions or investigations by the SEC or other regulatory authorities. In addition, if we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, or expresses an adverse opinion, investors may lose confidence in the accuracy and completeness of our financial reports, we may face restricted access to the capital markets and our stock price may be adversely affected.

We also face risks associated with the cost of establishing effective internal control over financial reporting, insofar as we expect to continue to incur increased costs related to our internal control over financial reporting to remediate the above-described material weaknesses and improve further our internal control environment. We have expended, and expect to continue to undertake various actions, such as implementing additional internal controls and procedures and hiring additional compliance, accounting and financial staff with appropriate public company experience and technical knowledge, to develop and maintain the necessary documentation and testing procedures required by Section 404 of the Sarbanes-Oxley Act. The measures we take to remediate the deficiency in our internal control over financial reporting and to implement and maintain effective internal controls may also not be sufficient to satisfy our obligations as a public company and produce reliable financial reports, and we may not be able to implement the required controls in a timely fashion, which could have the additional adverse consequences described above.

Changes in U.S. and foreign tax laws, particularly under the current U.S. presidential administration, could have a material adverse effect on our business, cash flow, results of operations or financial conditions.

We (as well as certain of our subsidiaries, including our subsidiary that is organized as a Singapore company) are subject to federal, state and local taxes in the United States and are also subject to tax in certain foreign jurisdictions. Changes to U.S. tax laws, including limitations on the ability of taxpayers to claim and utilize foreign tax credits and the deferral of certain tax deductions until earnings outside of the United States are repatriated to the United States, as well as changes to U.S. federal income tax laws, such as the recently enacted Inflation Reduction Act of 2022, and others that may be enacted in the future, could impact the tax treatment of our foreign earnings. Due to our international business activities, any changes in the taxation of such activities may increase our worldwide effective tax rate and adversely affect our financial position and results of operations.

Significant judgment is required in evaluating our tax positions and our worldwide provision for taxes. During the ordinary course of business, there are many activities and transactions for which the ultimate tax determination is uncertain. In addition, our tax obligations and effective tax rates could be adversely affected by changes in the relevant tax, accounting and other laws, regulations, principles and interpretations, including those relating to income tax nexus, if our earnings are lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where it has higher statutory rates, by changes in foreign currency exchange rates, or by changes in the valuation of its deferred tax assets and liabilities. We may be audited in various jurisdictions, and such jurisdictions may assess additional taxes against us. Although we believe our tax estimates are reasonable, the final determination of any tax audits or litigation could be materially different from our historical tax provisions and accruals, which could have a material adverse effect on our operating results or cash flows in the period or periods for which a determination is made.

Additionally, changes in corporate tax rates, the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings, and the deductibility of expenses under future tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase our future tax expense, which could have a material adverse effect on our business, financial condition, operating results, and prospects.

Certain U.S. state tax authorities may assert that we have a state nexus and seek to impose state and local income taxes which could harm our results of operations.

There is a risk that certain state tax authorities where we do not currently file a state income tax return could assert that we are liable for state and local income taxes based upon income or gross receipts allocable to such states. States are becoming increasingly aggressive in asserting a nexus for state income tax purposes. If a state tax authority successfully asserts that our activities give rise to a nexus, we could be subject to state and local taxation, including penalties and interest attributable to prior periods. Such tax assessments, penalties and interest may adversely impact our results of operations.

Risks Relating to Privacy and Security

If we experience a significant cybersecurity breach or disruption in our information systems or any of our partners’ information systems, our business could be adversely affected.

Malicious actors may be able to penetrate our network and misappropriate or compromise our confidential information or that of third parties, create system disruptions or cause shutdowns. Malicious actors also may be able to develop and deploy viruses, worms and other malicious software programs that attack our products or otherwise exploit any security vulnerabilities of our products. We manage and store various proprietary information and sensitive or confidential data relating to our business as well as information from our suppliers and customers. While we employ a number of protective measures, including firewalls, network infrastructure vulnerability scanning, anti-virus and endpoint detection and response technologies, these measures may fail to prevent or detect attacks on our systems due to the frequent evolving nature of cybersecurity attacks. Although these measures are designed to ensure the confidentiality, integrity and availability of our information and technology systems, there is no assurance that these measures will detect all threats or prevent a cybersecurity attack in the future. If there are any breaches of our or any of our third party suppliers’ security measures or the accidental loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential data about us or our employees, contractors, customers, suppliers, or other third parties, including the potential loss or disclosure of such information or data as a result of fraud, trickery or other forms of deception, it could expose us or our employees, contractors, customers, suppliers, or other third parties to a risk of loss or misuse of this information, disruption of business operations, result in litigation, regulatory scrutiny, and potential liability for us, damage our brand and reputation or otherwise harm our business.

29

Table of Contents

In addition, our hardware and software or third party components and software that we utilize in our products may contain defects in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation or security of the products. The costs to us to eliminate or mitigate cyber or other security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant and, if our efforts to address these problems are not successful, could result in interruptions, delays, cessation of service and loss of existing or potential customers that may impede our sales, manufacturing, distribution or other critical functions.

To the extent we experience cybersecurity incidents in the future, our relationships with our partners, suppliers and eventual customers may be materially impacted, our brand and reputation may be harmed and we could incur substantial costs in investigating, responding to and remediating the incidents, and in resolving any regulatory investigations or disputes that may arise with respect to them, any of which would cause our business, operations, or products to be adversely affected. In addition, the cost and operational consequences of implementing and adding further data protection measures could be significant.

Risks Relating to Our Common Stock and Warrants

Our CEO and certain entities affiliated with the CEO (the “SES Founder Group”) is a large and significant stockholder and, as a result, we are a “controlled company,” which exempts us from certain obligations to comply with certain corporate governance requirements.

As of March 10, 2023, the SES Founder Group owned approximately 12.5% of our outstanding common stock and 58.9% of the total voting power. Accordingly, we are a “controlled company” for purposes of the NYSE listing requirements. As such, we are exempt from the obligation to comply with certain corporate governance requirements, including the requirements that a majority of our board of directors must consist of independent directors, and that we have nominating and compensation committees that are each composed entirely of independent directors. These exemptions do not modify the requirement for a fully independent audit committee. If we cease to be a “controlled company,” we must comply with the independent board committee requirements as they relate to the nominating and compensation committees, subject to certain “phase-in” periods.

We are controlled or substantially influenced by the SES Founder Group, whose interests may conflict with other stockholders. The concentrated ownership of our dual class common stock could prevent stockholders from influencing significant decisions.

The SES Founder Group has the ability to control the outcome of most matters requiring stockholder consent. As our Chief Executive Officer, Dr. Hu has control over our day-to-day management and the implementation of major strategic investments, subject to authorization and oversight by our board of directors. As a board member and officer, Dr. Hu also owes a fiduciary duty to our stockholders and must act in good faith in a manner he reasonably believes to be in the best interests of our stockholders. However, Dr. Hu is still entitled to vote his shares, and has the ability to control the outcome of most matters requiring stockholder consent. This was designed to shepherd our long-term growth amidst significant near term fluctuations and uncertainty in the market.

Moreover, for so long as the SES Founder Group holds at least a majority of SES’s outstanding common stock, it has the ability, through the Board, to control decision-making with respect to SES’s business direction and policies. Matters over which the SES Founder Group can, directly or indirectly, exercise control include:

Even if the SES Founder Group’s ownership subsequently falls below 50%, the SES Founder Group may continue to be able to strongly influence or effectively control our decisions.

Provisions in our Certificate of Incorporation (the “Charter”) and Delaware law may inhibit a takeover attempt which could limit the price investors might be willing to pay in the future for our common stock and could entrench management.

Our Charter and Bylaws contain provisions to limit the ability of others to acquire control of us or cause us to engage in change-of-control transactions, including, among other things:

30

Table of Contents

These provisions could have the effect of depriving our stockholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of us in a tender offer or similar transaction. With our staggered Board, at least two annual meetings of stockholders will generally be required in order to effect a change in a majority of our directors. Our staggered Board can discourage proxy contests for the election of our directors and purchases of substantial blocks of our shares by making it more difficult for a potential acquirer to gain control of our Board in a relatively short period of time.

Our Charter provides, subject to limited exceptions, that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.

Our Charter requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware (the “Chancery Court”) and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to the personal jurisdiction of the Chancery Court and having service of process made upon such stockholder in any such action on such stockholder’s counsel. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to these forum provisions. Notwithstanding the foregoing, our Charter provides that the exclusive forum provision does not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended (the “Exchange Act”). 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. Additionally, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the “Securities Act”) against us or any of our directors, officers, other employees or agents. However, there is uncertainty as to whether a court would enforce the exclusive forum provisions relating to causes of actions arising under the Securities Act.

Although we believe this exclusive forum provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, it 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. Alternatively, if a court were to find the choice of forum provision contained in our Charter 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.

The price of our common stock has been and may continue to be volatile.

The market price of our Class A common stock is affected by a number of factors, including:

31

Table of Contents

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

Our public warrants may never be in the money, and they may expire worthless.

The exercise price for our warrants is $11.50 per-share, subject to adjustment, which exceeds the market price of our Class A common stock, which was $2.79 per-share based on the closing price of our Class A common stock on the NYSE on March 10, 2023. There can be no assurance that the public warrants will ever be in the money prior to their expiration and, as such, the warrants may expire worthless.

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

We may redeem outstanding warrants (excluding any private placement warrants held by the Ivanhoe Capital Sponsor LLC (the “Sponsor”) or its permitted transferees) at any time after they become exercisable and prior to their expiration, at $0.01 per warrant, provided that the last reported sales price (or the closing bid price of our Class A common stock in the event our Class A common stock is not traded on any specific trading day) of our Class A common stock equals or exceeds $18.00 per-share for any 20 trading days within a 30 trading-day period ending on the third business day prior to the date we send proper notice of such redemption, provided that on the date we give notice of redemption and during the entire period thereafter until the time we redeem the warrants, there is an effective registration statement under the Securities Act covering the shares of our Class A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available. If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding warrants could force a warrant holder: (i) to exercise its warrants and pay the exercise price therefore at a time when it may be disadvantageous for it to do so, (ii) to sell its warrants at the then-current market price when it might otherwise wish to hold its warrants or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, will be substantially less than the market value of its warrants.

Warrants to purchase SES common stock became exercisable on March 3, 2022, which could increase the number of shares eligible for future resale in the public market and result in dilution to stockholders.

As of the closing of the Business Combination, there were 14,213,280 warrants outstanding. Each warrant entitles its holder to purchase one share of Class A common stock at an exercise price of $11.50 per-share and will expire at 5:00 p.m., New York time, five years after the closing of the Business Combination or earlier upon redemption of our Class A common stock or our liquidation. To the extent warrants are exercised, additional shares of Class A common stock will be issued, which will result in dilution to our then existing stockholders and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could depress the market price of our Class A common stock.

We may be subject to securities litigation, which is expensive and could divert management’s attention.

The share price of our Class A common stock has been and may continue to be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. SES may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which

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

On February 3, 2022 (the “Closing Date”), SES consummated its previously disclosed business combination (the “Business Combination”). Prior to the closing of the Business Combination, Ivanhoe Capital Acquisition Corp. (“Ivanhoe”), a Cayman Islands exempted company, migrated out of the Cayman Islands and domesticated as a Delaware corporation (the “Domestication”) and changed its name to “SES AI Corporation.” On the Closing Date, SES AI Corporation and Wormhole Amalgamation Sub Pte. Ltd., a Singapore private company limited by shares and a direct, wholly-owned subsidiary of Ivanhoe (“Amalgamation Sub”), consummated the Business Combination, which was accounted for as a reverse recapitalization. Under this method of accounting, SES AI Corporation was treated as the “acquired” company for financial reporting purposes. Except as otherwise provided herein, our financial statement presentation includes (i) the historical operating results of Old SES prior to the Business Combination; (ii) the combined results of SES and Old SES following the Closing; (iii) the assets and liabilities of Old SES at their historical cost; and (iv) SES’s equity structure for all periods presented. See “Note 3 – Business Combination” set forth in Part II, Item 8 of this Annual Report on Form 10-K, for additional information.

The following discussion and analysis provides information which our management believes is relevant to an assessment and understanding of our consolidated results of operations and financial condition. The following discussion and analysis should be read in conjunction with our audited consolidated financial statements as of and for the years ended December 31, 2022 and 2021 and the accompanying notes included in this Annual Report on Form 10-K. The following discussion may contain forward-looking statements that reflect our plans, estimates and beliefs, which are subject to risks, uncertainties and assumptions. Our actual results and the timing of events may differ materially from those expressed or implied as a result of various factors, including those set forth in the sections titled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”

Overview

We are engaged in the development and production of high-performance, Lithium-Metal (“Li-Metal”) rechargeable battery technologies for electric vehicles (“EVs”), electric vehicle take-off and landing (“eVTOL”) and other applications. Our third-party tested, differentiated battery technology has been designed to combine the high energy density of Li-Metal with the cost-effective, large-scale manufacturability of conventional Lithium-ion (“Li-ion”) batteries and will help to promote the transition from the global dependence on fossil fuel-based automotive vehicles to clean and efficient EVs.

Our mission is to facilitate the widespread adoption of sustainable electric transportation, both on land and in air, by creating best-in-class, high energy density Li-Metal batteries centered around long-range performance and safety. To assist in achieving this mission, we have partnered with leading global original equipment manufacturers (“OEMs”), GM, Hyundai and Honda, among other strategic partners, under joint development agreements (“JDAs”) to jointly develop and produce our Li-Metal battery cells and technology. We are also conducting research and development activities to further improve the performance, quality and cost of our battery technologyby focusing on the following key areas, all of which we expect to help us achieve our commercialization goal, at our facilities in Woburn, Massachusetts in the United States, Shanghai, China, and Chungju, South Korea.

35

Table of Contents

During 2022, we continued to work towards developing and initially producing A-Sample batteries with specifications required by our OEM partners for their EVs. Our efforts resulted in 7 and 18 newly granted patents and trademarks and the construction of our pilot facilities in Shanghai, China and Chungju, South Korea. The Shanghai pilot facility was ready-to-use in March 2022 and fully operational in the third quarter of 2022, while the Chungju pilot facility ready-to-use in September 2022 and fully operational in the fourth quarter of 2022.

As we plan to transition the development and initial production of our Li-Metal batteries from A-sample to B-sample in 2023, we expect to significantly increase our headcount and the footprint of our research and pre-production pilot facilities by expanding our existing facilities and entering into new facilities. As a result, our materials consumption and the rate of cash utilization, as a function of time, will increase significantly.

After B-Sample, we plan to transition to C-Sample in 2024, which we then expect to enable us to commence commercial production of our technology in 2025. As the joint development of Li-Metal batteries with our OEM partners continues to progress, we also expect to launch future research facilities and, eventually, commercial production manufacturing facilities in the United States.

Finally, we expect to explore opportunities for partial vertical integration, both upstream and downstream, to ensure scalability of our battery and battery technology. Upstream, we intend to explore integrating vendors of key materials of our cells and providers of key equipment and engineering capabilities, such as cell assembly, anode processing, chemical processing and safety testing. Downstream, we plan to explore integrating providers of key engineering capabilities, such as battery state-of-health monitoring software, charging optimization software, battery module development and recycling.

Results of Operations

The discussion of our results of operations for the year ended December 31, 2021 can be found in Exhibit 99.2 Management’s Discussion and Analysis of Financial Condition and Results of Operations under our Amendment No. 1 Form 8-K (the “Super 8-K Amendment”) for the fiscal year ended December 31, 2021 filed with the Securities and Exchange Commission on March 31, 2022, which is incorporated herein by reference.

Factors Affecting Operating Results

We are an early-stage growth company in the pre-commercialization stage of development, and conduct our business through one operating segment. We have not generated any revenue from sales to customers to date, have spent $42.2 million, $31.5 million, and $9.4 million on research and development activities, which is prior to credits received by our OEM partners under the JDAs, and have incurred net losses of $51.0 million, $31.3 million, and $13.9 million for the years ended December 31, 2022, 2021 and 2020, respectively, and had an accumulated deficit of $145.3 million and $94.3 million from our inception through December 31, 2022 and 2021, respectively. Our historical results may not be indicative of our future results for reasons that may be difficult to anticipate and our ability to generate revenue in the future that is sufficient enough to achieve profitability will depend largely on the successful development of our products. Accordingly, the drivers of our future financial results, as well as the components of such results, may not be comparable to our historical results of operations.

During 2021 and 2022, we were subject to challenging conditions stemming from the COVID-19 pandemic. Previous spikes in COVID-19 cases in Shanghai resulted in government-mandated temporary shutdowns at our Shanghai facility in April 2022, causing a delay of over a month in our development, testing and manufacturing efforts and in our product schedule and our ability to obtain materials from our suppliers in the affected area. The government-mandated shutdown was lifted on June 1, 2022 and the Shanghai facility has re-opened. If our workforce is unable to work effectively, including due to illness, quarantines, government actions or other restrictions in connection with COVID-19, our operations will be adversely affected. See “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K for further discussion of the possible impact of the COVID-19 pandemic on our business.

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

Table of Contents

Operating Expenses

​

​

Research and Development

Research and development expenses consist primarily of costs incurred for salaries and personnel-related expenses, including stock-based compensation expense, for scientists, experienced engineers and technicians, expenses for materials and supplies used in product research and development, process engineering efforts and testing, as well as payments to consultants, patent related legal costs, depreciation, and allocated facilities and information technology costs.

Research and development expenses for the year ended December 31, 2022 increased $12.5 million, or 80%, to $28.0 million, compared with $15.5 million for the year ended December 31, 2021. The increase primarily resulted from a $8.2 million increase in personnel costs mainly attributable to our growth in headcount in support of our ongoing research and development efforts for battery cell development, which included $6.3 million of stock-based compensation expense that primarily relates to restricted earnout shares issued as part of the Business Combination in February 2022 and restricted and performance stock units issued in April 2022. Further, there was a $4.5 million increase in software development costs related to our advanced AI software and BMS, a $1.8 million increase in facility costs due to rent, utilities and depreciation expenses, and a $1.4 million increase in expenses for lab consumables and material supplies. These increases were partly offset by a $3.2 million increase in credits to research and development expense, which are amounts invoiced pursuant to the JDAs, and a $0.3 million decrease in fees associated with external consulting. We expect research and development expenses to significantly increase in 2023 compared with 2022 as we attempt to develop a battery cell with acceptable performance, yields and costs due to expansion of our science, engingeering, and technician personnel and investments in additional plant and equipment for product development, building prototypes and testing of battery cells.

General and Administrative

General and administrative expenses consist primarily of costs incurred for salaries and personnel-related expenses, including stock-based compensation expense, for our finance, legal and human resource functions, expenses for director and officer insurance, outside contractor and professional service fees, audit and compliance expenses, legal, accounting and other advisory services, as well as allocated facilities and information technology costs including depreciation. Upon commencement of commercial operations, we also expect to incur customer and sales support and advertising costs.

General and administrative expenses for the year ended December 31, 2022 increased $35.1 million, or 213%, to $51.6 million, compared with $16.5 million for the year ended December 31, 2021. This increase primarily resulted from a $17.5 million increase in personnel costs mainly attributable to our growth in headcount to support our operations as a public company, which included $11.9 million of stock-based compensation expense that primarily relates to restricted earnout shares issued as part of the Business Combination in February 2022 and restricted and performance stock units issued in April 2022. Further, there was a $7.5 million increase in insurance expense to cover potential liabilities under our indemnification obligations to our directors and certain officers of the Company, a $4.6 million increase in fees associated with external consulting, legal, marketing, public relations, audit and accounting services, a $3.4 million increase due to deferred offering costs associated with the Business Combination, a $1.1 million increase in facility costs due to rent, utilities and depreciation, a $0.6 million increase in travel costs primarily related to the opening of the South Korea facility, and a $0.4M increase in computer and software related costs. We expect general and administrative expenses to increase in 2023 compared with 2022 due to expansion of our personnel headcount to support our growth and operations as a public company.

Non-Operating Items

Interest Income, Net

Interest income primarily consists of interest earned on our cash and cash equivalents, which are primarily invested in money market funds, and short-term investments in marketable securities, which are invested in U.S. treasury securities, and accretion income from the marketable securities.

37

Table of Contents

During the year ended December 31, 2022, we had interest income of $6.2 million compared with $0.2 million for the year ended December 31, 2021. This $6.0 million increase was primarily due an increased investment in money market funds, a shift of a portion of our investment portfolio in the current year from cash and cash equivalents to higher yielding investments in U.S. treasury securities, and a general increase in interest rates during 2022.

Change of Fair Value of Earn-Out Liability, Net

During the year ended December 31, 2022, we incurred a $25.4 million gain associated with the change in fair value of the Sponsor Earn-Out liability. With the fair value of the Sponsor Earn-Out liability tied to the Company’s stock price, continued volatility in the stock price could result in further gains or losses resulting from the change in fair value. See “Note 11 – Sponsor Earn-Out Liability” to the consolidated financial statements for additional information.

Other (Expense) Income, Net

During the year ended December 31, 2022, we had other expense of $1.8 million, compared with other expense of $0.3 million for the year ended December 31, 2021. This $1.5 million increase in other expense was primarily the result of the accounting for certain postemployment benefits and a gain recorded in the prior year from the forgiveness of the PPP note received in 2020, partially offset by unrealized and realized foreign currency gains primarily due to the strengthening of the U.S. dollar compared with the Chinese renminbi and South Korean won.

Provision for Income Taxes

Income tax expense was $1.3 million on pre-tax loss of $49.7 million for the year ended December 31, 2022 compared with an immaterial income tax expense on pre-tax loss of $31.2 million for the year ended December 31, 2021. Our effective tax rate was (2.5)% and (0.1%) for the years ended December 31, 2022 and 2021, respectively. The difference between our effective tax rate and the U.S. federal statutory rate of 21% was primarily driven by non-recognized deferred tax benefits due to a full valuation allowance. See to “Note 18 – Income Taxes” to the consolidated financial statements for additional information on our income tax expense.

Liquidity and Capital Resources

On February 3, 2022, as a result of the aforementioned Business Combination and PIPE Financing, we raised $282.9 million in net proceeds. Prior to that, since our inception we raised approximately $269.9 million of funding through the sales of our redeemable convertible preferred stock. As of December 31, 2022, we had total cash and cash equivalents of $106.6 million, short-term investments in marketable securities of $283.5 million, and an accumulated deficit of $145.5 million. As an early-stage growth company in the pre-commercialization stage of development, the net operating losses we have incurred since inception are consistent with our strategy and budget.

As a result of the capital-intensive nature of our business, we expect to sustain substantial operating expenses, without generating sufficient revenues to cover expenditures, for a number of years. To date, we have funded our operations through a combination of proceeds from the Business Combination and PIPE Financing and funding received through the sales of our redeemable convertible preferred stock. These funds are expected to finance our principal sources of liquidity and ongoing costs, such as research and development relating to our Li-Metal batteries and the construction of additional manufacturing facilities. In the future, if we are not able to fund our operations from cash flows generated from anticipated product sales, we expect that we will need to raise additional funds through a variety of possible methods, including, but not limited to, entry into joint ventures or other strategic arrangements, issuance of equity, equity-related or debt securities or through obtaining credit from financial institutions, as well as anticipated future revenue from product sales.

We believe that our cash on hand and marketable securities will be sufficient to meet our working capital and capital expenditure requirements for a period of at least 12 months from the date of this Report, and also sufficient to fund us to commercialization. However, additional funding may be required for a variety of reasons, including opportunities to build an integrated supply chain in the United States and delays in expected development of our Li-Metal battery cells. Our ability to successfully develop our products, commence commercial operations and expand our business will depend on many factors, including our working capital needs, the availability of equity and/or debt financing and, over time, our ability to generate positive cash flows from operations.

Summary of Cash Flows

The following table provides a summary of our cash flow data for the periods indicated:

​

Operating Activities

Our cash flows used in operating activities to date have been primarily comprised of payroll, consumables and supplies related to research and development, expenditures and reimbursements related to our JDAs, and facilities expense and professional services for general and administrative activities. As we continue to ramp up hiring for research and development headcount to accelerate our engineering efforts, we expect our cash used in operating activities to increase significantly before we start to generate any material cash inflows from our operations.

Net cash used in operating activities of $46.5 million for the year ended December 31, 2022 was primarily attributable to net loss of $51.0 million, as adjusted for a gain on change in fair value of Sponsor Earn-Out liability of $25.4 million, stock-based compensation expense of $22.8 million, depreciation and amortization expense of $2.6 million and accretion income from available-for-sale short-term investments of $2.4 million, partially offset by a $6.4 million working capital inflow. The working capital inflow was driven by a $6.8 million increase in accrued expenses and other liabilities and a $5.5 million decrease in receivable from related party, partially offset by a $4.0 million decrease in accounts payable and a $1.6 million increase in prepaids and other assets. The increase in accrued expenses and other liabilities was primarily due to advanced payments received under the JDAs, accrued income taxes payable, payroll related accruals and the accounting of certain postemployment benefits. The decrease in receivable from related party was driven by activity from a JDA. The decrease in accounts payable was primarily due to the payment of transaction costs related to the Business Combination and PIPE Financing partially offset by an increase in accounts payable related to the purchase of property and equipment for the South Korea facility. The increase in prepaids and other assets was primarily due to insurance costs to cover potential liabilities under our indemnification obligations to our directors and certain officers.

Net cash used in operating activities of $30.0 million for the year ended December 31, 2021 was primarily attributable to net loss of $31.3 million, as adjusted for stock-based compensation expense of $4.6 million, depreciation and amortization of $1.7 million and gain on the forgiveness of the PPP note payable of $0.8 million, partially offset by a $4.2 million working capital outflow. The working capital outflow was primarily driven by a $7.9 million increase in receivable from related party and a $1.7 million increase in prepaids and other assets, partially offset by a $4.1 million increase in accrued expenses and other liabilities and a $1.3 million increase in accounts payable. The increase in receivable from related party was driven by activity from a JDA. The increase in prepaids and other assets was primarily attributable to prepaid rent and deposits related to the Shanghai facitlity. The increase in accrued expenses and other liabilities was primarily attributable to increased marketing and public relations activity and a prepayment attributable to a JDA. The increase in accounts payable was primarily attributable to professional fees associated with external legal, consulting and accounting services.

Investing Activities

Net cash used in in investing activities was $296.0 million for the year ended December 31, 2022, compared with net cash provided by investing activities of $3.3 million for the year ended December 31, 2021.

Purchases and Maturities of Investments – Net purchases of short-term investments were $281.4 million for the year ended December 31, 2022, compared with net proceeds from maturities of short-term investments of $12.3 million for the year ended December 31, 2021. The $293.6 million decrease in net proceeds was driven by a shift of our investment portfolio to cash equivalents in the current year.

Capital Spending – Capital expenditures were $14.7 million and $9.0 million for the years ended December 31, 2022 and 2021, respectively, and primarily related to purchases of lab machinery and equipment, lab tools and instruments and leasehold improvements to our facilities

39

Table of Contents

in the United States, Shanghai and South Korea. We expect capital expenditures to significantly increase in 2023 compared with 2022 as we continue to invest in the build out of our manufacturing pre-production facilities and expand into new facilities.

Financing Activities

Net cash provided by financing activities of $289.9 million for the year ended December 31, 2022 was primarily attributable to proceeds received from the Business Combination and PIPE Financing, net of transaction costs and from a government grant.

Net cash provided by financing activities of $184.8 million for the year ended December 31, 2021 related to proceeds received from the issuance of Series D and D plus redeemable convertible preferred stock, net of issuance costs.

Debt

In April 2020, we applied for and received $0.8 million in the PPP note. We received full forgiveness of all our debt under the terms of the program in February 2021 and recorded a gain of $0.8 million in other income in our consolidated statement of operations and comprehensive loss for the year ended December 31, 2021. As of the date of this filing, we have no debt obligations outstanding.

Contractual Obligations and Commitments

The following table summarizes our material contractual obligations for cash expenditures as of December 31, 2022, and the periods in which these obligations are due:

​

⁽¹⁾ Purchase obligations include commitments for the purchase of lab supplies and equipment as well as committed spend related to a JDA. These commitments are derived from purchase orders, supplier contracts and open orders based on projected demand information.

⁽²⁾ Operating lease obligations represent the fixed lease payments for the noncancelable lease term, fixed lease payments for optional renewal periods where the Company is reasonably certain the renewal option will be exercised, and variable lease payments that depend on an underlying index or rate in effect at lease commencement.

Off-Balance Sheet Arrangements

As of December 31, 2022, we had a letter of credit issued by a financial institution totaling $0.6 million. The letter of credit relates to deposits the Company is required to maintain under one of its operating leases agreements. We have restricted cash that serves as collateral for this outstanding letter of credit that is included in other assets on our consolidated balance sheet. No amounts have been drawn under the letter of credit.

Recent Accounting Pronouncements

See “Note 2 – Summary of Significant Accounting Policies” of our accompanying consolidated financial statements included in this Annual Report on Form 10-K for more information about recent accounting pronouncements, the timing of their adoption, and their potential impact on our financial condition, results of operations and cash flows.

Critical Accounting Estimates and Judgments

Our consolidated financial statements have been prepared in accordance with U.S. GAAP which requires management to use judgment in making estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported expenses incurred during the reporting periods.

We consider an accounting estimate or assumption to be critical when (1) the estimate or assumption is complex in nature or requires a high degree of judgment and (2) the use of different judgments, estimates and assumptions could have a material impact on the financial statements. Our significant accounting policies are described in “Note 2 – Summary of Significant Accounting Policies” of our accompanying consolidated financial statements included in this Annual Report on Form 10-K. We consider the following to be our critical accounting estimates.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to a variety of markets and other risks including the effects of change in interest rates, inflation and foreign currency translation and transaction risks as well as risks to the availability of funding sources, hazard events and specific asset risks.

Interest Rate Risk

The market interest risk in our financial instruments and our financial positions represents the potential loss arising from adverse changes in interest rates. As of December 31, 2022, we had cash and cash equivalents of $106.6 million, primarily consisting of interest-bearing money market funds, and short-term investments of $283.5 million, consisting U.S treasury securities, respectively. A 100 basis point increase in the general level of U.S. interest rates relative to interest rates as of December 31, 2022 would decrease the fair value of our short-term investments by approximately $1.6 million. This estimate is based on a sensitivity model that measures market value changes when changes in interest rates occur. Such decrease in fair value would only be realized if we sold the investments prior to maturity.

Foreign Currency Risk

The functional currency of all our entities and all its subsidiaries is the U.S. dollar, except for our subsidiaries in China and South Korea, which has Chinese renminbi (RMB) and South Korean won (KRW), respectively, as its functional currency, reflecting its principal operating economic environment. We expect to be exposed to both currency transaction remeasurement and translation risk. Net realized and unrealized gains (losses) from foreign currency transactions are included in other expense, net in the consolidated statement of operations and comprehensive loss and amounted to a gain of $0.1 million for the year ended December 31, 2022. This foreign transaction gain was primarily due to the strengthening of the U.S. dollar to the Chinese renminbi (RMB) and South Korean won (KRW). We have not hedged such exposure, although we may do so in the future.

SES AI Corporation:

​

Opinion on the Consolidated Financial Statements

​

We have audited the accompanying consolidated balance sheets of SES AI Corporation and subsidiaries (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss, redeemable convertible preferred stock and stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the three-year 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 (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 16, 2023 expressed an adverse opinion on the effectiveness of the Company’s internal control over financial reporting.

​

Change in Accounting Principle

​

As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for leases as of January 1, 2022 due to the adoption of Accounting Standards Update 2016-02, Leases (Topic 842), as amended.

​

Basis for Opinion

​

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

​

Critical Audit Matters

​

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

​

Valuation of sponsor earn-out liability

​

As discussed in Notes 2, 3 and 11 to the consolidated financial statements, on February 3, 2022, the Company completed a business combination that was accounted for as a reverse recapitalization, and the Company was determined to be the accounting acquirer. In connection with the business combination, 6,900,000 shares of Class B ordinary shares held by Ivanhoe Capital Sponsor LLC (the “Sponsor”) were converted into an equal number of Class B common stock of the Company that were converted on closing of the business

44

Table of Contents

combination into an equal number of Class A common stock of the Company (the “Sponsor Earn-Out Shares”). Certain Sponsor Earn-Out Shares are accounted for as a derivative liability (the “Sponsor Earn-Out Liability”) measured at fair value, with changes in fair value recorded in the consolidated statement of operations and comprehensive loss at each reporting period. The fair value of the Sponsor Earn-Out Liability is estimated using a Monte Carlo simulation model. The fair value of the Sponsor Earn-Out Liability was determined to be $36,393,000 at February 3, 2022, and $10,961,000 at December 31, 2022. The gain on change of fair value of Sponsor Earn-Out Liability was $25,432,000 for the year ended December 31, 2022.

​

We identified the assessment of the fair value of the Sponsor Earn-Out Liability as a critical audit matter. Specifically, a high degree of subjective auditor judgment was required due to the complex valuation model and volatility assumptions used in the determination of fair value. It also required specialized skills and knowledge to evaluate the Company’s determination of the fair value of the Sponsor Earn-Out Liability.

​

The following are the primary procedures we performed to address this critical audit matter. We evaluated the peer group public companies used in the determination of volatility assumptions by reviewing the business descriptions of the peer group public companies to determine if the peer group public companies are reasonably comparable in terms of the Company’s industry. We involved valuation professionals with specialized skills and knowledge who assisted in (1) evaluating the appropriateness of the Monte Carlo simulation model (2) performing independent calculations of volatility using peer group public companies’ data and comparing to volatility assumptions utilized in management’s estimate and (3) performing an independent calculation of the fair value using management’s assumptions and comparing to the fair value of the Sponsor Earn-Out Liability determined by the Company.

​

Valuation of certain stock-based compensation awards

​

As discussed in Note 17 to the consolidated financial statements, during the year ended December 31, 2022, the Company issued various share-based awards, including restricted stock units, restricted stock awards, performance stock units, as well as earn-out restricted shares granted in connection with the business combination completed on February 3, 2022. The performance stock units and earn-out restricted shares have both service and market vesting conditions. The fair value of the performance stock units and earn-out restricted shares was estimated using a Monte Carlo simulation model. The Company reported stock-based compensation expense of $22,775,000 for the year ended December 31, 2022.

​

We identified the assessment of fair value of the performance stock units and earn-out restricted shares granted in connection with the business combination as a critical audit matter. Specifically, a high degree of subjective auditor judgment was required due to the complex valuation model and volatility assumptions used in the determination of fair value. It also required specialized skills and knowledge to evaluate the Company’s determination of the fair value of the performance stock units and earn-out restricted shares.

​

The following are the primary procedures we performed to address this critical audit matter. We evaluated the peer group public companies used in the determination of volatility assumptions by reviewing the business descriptions of the peer group public companies to determine if the peer group public companies are reasonably comparable in terms of the Company’s industry.  We involved valuation professionals with specialized skills and knowledge who assisted in (1) evaluating the appropriateness of the Monte Carlo simulation model (2) performing independent calculations of volatility using peer group public companies’ data and comparing to volatility assumptions utilized in management’s estimate and (3) performing an independent calculation of the fair value using management’s assumptions and comparing to the fair value of the performance stock units and earn-out restricted shares determined by the Company.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
SES AI Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited SES AI Corporation and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, because of the effect of the material weaknesses, described below, on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

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 and comprehensive loss, redeemable convertible preferred stock and stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, (collectively, the consolidated financial statements), and our report dated March 16, 2023 expressed an unqualified opinion on those consolidated financial statements.

​

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses have been identified and included in management’s assessment related to certain components of the Company’s control environment that were ineffective as the Company did not have a sufficient complement of resources with assigned responsibility and accountability for the design, operation and documentation of internal control over financial reporting. This created deficiencies in the Company’s risk assessment process that led to ineffective information and communication activities as the controls necessary to ensure the reliability of information used in financial reporting and communicate relevant information about roles and responsibilities for internal control over financial reporting were ineffective. As a result, process-level control activities were not designed, implemented or operated effectively in the substantial majority of processes. The material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the December 31, 2022 consolidated financial statements, and this report does not affect our report on those consolidated financial statements.

​

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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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

46

Table of Contents

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.

Note 1.  Nature of Business

SES AI Corporation, and consolidated subsidiaries (together the “Company”) consists of SES AI Corporation (“SES”) and its wholly-owned subsidiary SES Holdings Pte. Ltd. (“SES Holdings” or “Old SES”), along with its wholly owned subsidiaries SolidEnergy Systems, LLC (“SES LLC”), SolidEnergy (Shanghai) Co., Ltd. (“SES Shanghai”), SolidEnergy Systems Securities Corporation (“SES Securities”), Viking Power Systems Pte. Ltd. (“SES Viking”), SES AI Korea Co., Ltd. (“SES Korea”) and SES Energy Pte. Ltd.

See “Note 3 – Business Combination” for additional information.

​

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and have been prepared on a going concern basis and in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). The Company’s fiscal year ends on December 31.

As a result of the Business Combination completed on February 3, 2022, prior period share and per share amounts presented in the accompanying consolidated financial statements and these related notes have been retroactively converted.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make use of estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of commitments and contingencies, and the reported

52

Table of Contents

amounts of revenues, if any, and expenses. The Company bases its estimates on available historical experience and on various other factors that the Company believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from those estimates.  

Significant estimates and assumptions include those related to the valuation of (i) certain equity awards, including common stock awards prior to the Business Combination, the Sponsor Earn-Out Shares, the Earn-Out Restrcited Shares, and performance stock units, (ii) deferred tax assets and uncertain income tax positions, and (iii) and the measurement of operating lease liabilities. On an ongoing basis, the Company evaluates these judgments and estimates for reasonableness.

Foreign Currency Translation

For the foreign subsidiaries of the Company, assets and liabilities are translated into U.S. dollars using exchange rates as of the balance sheet date, and income and expenses are translated using the average exchange rates in effect for the related month. The net effect of these translation adjustments is reported in accumulated other comprehensive (loss) income within total stockholders’ equity on the consolidated balance sheets. Net realized and unrealized gains (losses) from foreign currency transactions are included in other expense, net in the consolidated statement of operations and comprehensive loss and were $0.1 million, $(0.2) million, and $(0.1) million for the years ended years ended December 31, 2022, 2021 and 2020, respectively.

Reclassification of Prior Period Amounts

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. Restricted cash and deferred offering costs have been combined with other assets and accrued compensation has been combined with accrued expenses and other current liabilities on the prior year consolidated balance sheet. The impact of these changes was an increase of $6.2 million to other assets and an increase of $2.1 million to accrued expenses and other current liabilities as of December 31, 2021. In addition, the Company reclassified the change in other assets to the change in prepaid expenses and other assets and the change in accrued compensation to the change in accrued expenses and other liabilities in the prior years statements of cash flows in the amount of $0.5 million and $0.9 million for the year ended December 31, 2021, respectively, and $0.1 million and $0.6 million for the year ended December 31, 2020, respectively. There was no change to previously reported total assets, total liabilities, or net cash used in operating activities.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and highly liquid investments that have original maturity periods of 90 days or less at the time of purchase that are readily convertible to known amounts of cash.

Restricted Cash

Restricted cash includes cash held in checking and money market funds as collateral to secure certain insurance policies and a letter of credit for corporate lease activity. The letter of credit is required to be maintained throughout the term of the lease. If the date of availability or disbursement is less than one year, restricted cash is reported within prepaid expenses and other current assets on the consolidated balance sheets. If the date of availability or disbursement is longer than one year and the balances are maintained under an agreement that legally restricts the use of such funds, restricted cash is reported within other assets on the consolidated balance sheets. As of December 31, 2022, no amount has been drawn under the letter of credit.

Investments in Short-term Investments

Investments in short-term investments consist of U.S. treasury securities. Investments with a stated maturity date of less than one year are classified as short-term investments, while investments with a stated maturity date of more than one year, and that are not expected to be used in current operations, are classified as long-term investments on the consolidated balance sheet, respectively. These available-for-sale marketable securities are recorded at fair value, with any unrealized gains and losses included as a component of accumulated other comprehensive (loss) income in total stockholders’ equity on the consolidated balance sheets until realized or until a determination is made that an other-than-temporary decline in market value has occurred. The amortized cost of U.S. treasury securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are reported within interest income, net in the consolidated statement of operations and comprehensive loss.
