PART I

Item 1. Business.

Fiscal 2025 Overview and Subsequent Developments

During the year ended December 31, 2025, our business consisted of our legacy solar operations conducted through the Subsidiary. Accordingly, references in this Item 1 to the terms “Sono Motors,” “Sono,” “the Companies,” “we,” “our,” “ours,” “ourselves,” “us” or similar terms, refer to Sono Group N.V. together with the Subsidiary with respect to the fiscal years ended December 31, 2025 and 2024, and refer to Sono Group N.V. with respect to subsequent developments as described below, unless the context requires otherwise.

Digital Asset Treasury

Subsequent to December 31, 2025, as previously announced by the Company, we established a digital asset treasury strategy and digital asset treasury policy (the “Treasury Strategy”). Under the Treasury Strategy, the principal holding in the Company’s treasury reserve on its balance sheet will be allocated to digital assets, principally Bitcoin, by applying a covered-call yield strategy.

In connection with the Treasury Strategy, on March 10, 2026, the Company entered into an International Swaps and Derivatives Association, Inc. (“ISDA”) 2002 ISDA Master Agreement, dated as of March 10, 2026 (the “ISDA Master Agreement”) with Blockchain.com (BVI) II Limited, a business company incorporated under the laws of the British Virgin Islands (“Blockchain.com”), facilitating the Company to enter into derivative and/or hedging transactions (collectively, the “Transactions”) to manage the risk associated with the Treasury Strategy. The derivative and hedging transactions will be governed by the ISDA Master Agreement, including the related Schedule to the ISDA Master Agreement executed by the Company and Blockchain.com on March 10, 2026 (the “Schedule”). The structure of the Transactions may include forwards, swaps, futures, options or other derivatives transactions in respect of digital assets. Certain events of default will apply to the Transactions under the ISDA Master Agreement and Schedule, including, but not limited to, failure to pay or deliver, breach of the agreement, credit support default, cross-defaults and misrepresentation. In addition, in connection with the ISDA Master Agreement, the Company and Blockchain.com entered into a Credit Support Annex to the Schedule to the ISDA Master Agreement, dated as of March 10, 2026 (the “Credit Support Annex”), which sets forth the terms and conditions upon which the Company will be required to deliver additional collateral to Blockchain.com (and Blockchain.com will be required to return collateral to the Company) depending upon the mark to market exposure under the ISDA Master Agreement and the value of the collateral. The ISDA Master Agreement, the Schedule and the Credit Support Annex are governed by the laws of England and Wales.

The Company may use available liquidity, including proceeds from previously disclosed financing arrangements, to purchase Bitcoin and other digital assets, subject to applicable law and public disclosure requirements. The Company intends to solicit the ratification by its shareholders of the engagement by the Company in the Treasury Strategy.

Exit from Legacy Solar Operations through Sono Motors GmbH

As previously announced by the Company, on March 14, 2026, our supervisory board resolved to terminate all current and future funding commitments to the Subsidiary and to exit the legacy solar operations conducted through the Subsidiary, with immediate effect. The Company’s decision was driven by the Subsidiary’s historical lack of profitability, which has resulted in the Company having to continuously provide funding to the Subsidiary, and thus incur losses, and a determination by the supervisory board that there was not a clear path for the Subsidiary to achieve profitability in a reasonably desirable timeframe and thus, avoid future losses by the Company. This decision was made in conjunction with the decision on March 14, 2026 by the Company’s management board, with the approval of the supervisory board, to adopt the Treasury Strategy. The Treasury Strategy is projected to generate cash flow for the Company in the first year of its execution. The Company is also exploring other strategic alternatives to maximize shareholder value.

The Company is currently unable to make a good faith estimate of the total costs and charges, if any, that may be incurred in connection with the cessation of funding to the Subsidiary and the exit from the Company’s legacy solar business. The determination of any such costs is subject to significant uncertainties, including, among other things, the timing, scope and manner of any actions undertaken with respect to the Subsidiary following the cessation of funding, as well as the extent of any obligations of the Company in connection therewith. Potential costs, if any, may include legal, advisory and other professional fees and expenses associated with activities relating to the Subsidiary. Any such costs and expenditures, if incurred, are expected to be reduced by cash flow to the Company from the Treasury Strategy.

Overview of Legacy Solar Operations through Sono Motors GmbH

We believe we are a pioneer in the field of solar-powered mobility applications. We envision a world that no longer relies on the burning of fossil fuels. After terminating our Sion passenger car program (the “Sion”) due to a lack of available funding at the end of February 2023, we pivoted our business model to focus exclusively on retrofitting and integrating our proprietary solar technology onto third party vehicle with an initial focus on our Solar Bus Kit.

In 2024, we expanded our product portfolio beyond the Solar Bus Kit to include similar solar integration solutions for additional commercial vehicle categories, including trucks, vans, RVs, refrigerated trailers, coach buses and panel vans. This strategic expansion is intended to align with the growing demand for sustainable energy solutions across multiple transportation sectors, allowing us to address a broader range of manufacturers and fleet operators looking to reduce fuel costs and emissions.

Expanding beyond our low-voltage retrofit solar solutions, in the beginning of 2025, we increased our offerings to also include high-voltage solar solutions, leveraging our proprietary solar charge controller, also known as the MCU. This advanced technology enables seamless solar energy integration into the high voltage system of commercial vehicles with larger energy demands. Additionally, we adjusted our distribution strategy and increased our focus on direct collaborations with original equipment manufacturers (“OEMs”) and certain partners including cooling unit and battery manufacturers. Building on a series of pilot projects, we aimed to collaborate with OEMs and certain partners to integrate our complete solar solutions and standalone solar products into vehicle structures, and work toward collaborations with several OEMs for specific vehicles, which could enable customers to select solar-powered options at the time of vehicle or trailer purchase. This approach was designed to enhance accessibility and scalability while streamlining adoption for commercial fleets.

Solar Technology

We have developed several innovative technologies for use in the mobility area and have been approached by a number of companies, such as manufacturers of trucks, commercial vehicle equipment and public transport operators, to provide them with access to our technology. We believe these technologies will offer users a unique experience and increased practicability of their vehicles.

Our solar technology allows for full solar integration in all kinds of vehicles, and while our initial focus, following the restructuring of our business and the pivot of our business model, was on low-voltage solar retrofit solutions for commercial vehicles, such as our Solar Bus Kit, we expanded our offerings in 2025 to include high-voltage solutions for commercial vehicles with larger energy demands. In addition, we increased our focus on commercializing complete solar solutions as well as standalone solar products and services, and on direct collaborations with OEMs. In the process of developing the Sion, we soon realized that the solar technology that was available at the time was not well-suited for mobility applications. Solar technology has traditionally been developed and used in stationary use cases. Also, automotive use of solar technology differs significantly in terms of functionality and regulatory requirements. For example, fast-changing sunlight conditions while driving and mechanical stress, such as vibrations, are not seen in stationary applications. Additionally, solar solutions for mobility use cases must comply with automotive regulations that drastically differ from regulations applicable to stationary applications. In order to enable the use of solar components on vehicles, Sono Motors developed new technical solutions for our proprietary solar charge controllers and power electronics, innovative integration methods for vehicle applications and thorough qualification methods to qualify solar module suppliers. These technologies and qualification procedures have been tested, evaluated and, in some cases, certified for automotive use.  Today our technology enables us to produce high-efficiency solar integration systems for delivering solar energy to vehicles.  Our solar technology can reduce running costs significantly and thereby reduce the total cost of ownership, a key point of focus for fleet operators, particularly those in the transport and logistics industries. Manufacturers may also use our technology for new production vehicles.

We have built a strong and diverse intellectual property portfolio, with 9 granted patents, 3 international Patent Cooperation Treaty (“PCT”) applications, 28 non-PCT patent applications or European patent (“EP”) applications and 3 utility models, collectively forming 26 patent families (i.e., independent inventions). Our patents cover critical innovations across key areas of vehicle-integrated photovoltaics (“ViPV”), solar energy conversion and power management systems. A significant portion of our portfolio (16 patent families) is focused on ViPV components and manufacturing, reflecting our leadership in integrating solar technology directly into commercial vehicles. By continuously refining our proprietary technology, we strengthen our competitive edge, enabling scalable OEM integration and long-term market leadership in solar mobility.

Solar Modules Specifically Designed for ViPV

Solar modules specifically designed for ViPV are a core part of our solar integration business. This approach utilizes specific solar technology based on polymers, rather than glass, on the large flat surfaces on the top or sides of vehicles, which are especially abundant in commercial vehicles. The solar modules can easily be mounted on vehicles during series production processes or even after they have been fully built. The application of these semi-flexible, light-weight modules on the exterior of vehicles has little influence on the substructure, design or homologation and type approval processes, which eases an integration of the solar technology. In fiscal year 2025 we focused on multiple use cases for our ViPV products and offer a range of solar integration solutions, including our Solar Bus Kit and our solar kits for trucks, vans, RVs, refrigeration trailers and other applications.

A ViPV approach involves the integration of specific types of semi-flexible solar modules into the vehicle. The relevant solution is developed and tested based on the needs of the specific customer, taking into account the expected lifetime of the vehicle, weight and cost specifications, installation times and synergies between solutions for different vehicle types. We have installed ViPV solutions on prototypes for multiple customers, including, among others, VBR Verkehrsbetriebe und Servicegesellschaft mbH, Scania CV AB, Koegel Trailer GmbH, Jean CHEREAU S.A.S, Hofbus GmbH and Stadtwerke Muenchen GmbH. Over time, we have improved our technologies significantly, for example, by reducing system costs, improving installation methods, shortening installation times and eliminating software bugs and telematics issues to increase system uptimes. In addition, we have gained a broad range of experience by working with various customers on ViPV applications for a variety of commercial vehicle types, including trailers, diesel buses, hybrid buses, electric buses and electric vans. Continuous technical and cost improvements are being implemented through our technology and operations departments to enable attractive business cases for customers at high volumes.

Solar Charge Controller (MCU)

The integration of solar modules into energy systems for transport-related use cases requires solar charge controllers that fit the vehicle E/E (electrical/electronic) architecture with its powertrain and auxiliary systems. Our solar charge controller, or MCU, is the central piece of our power electronics. Our MCU is a multichannel, dynamic system that is both conversion and tracking efficient. Our power electronics optimize the power output through the use of intelligent algorithms and energy earnings for solar modules mounted on, or integrated into, moving objects by a multichannel approach that considers quickly-changing sun radiation conditions and differently-oriented solar modules. Our MCU and algorithms allow for fast adaptation to changing sun conditions, resulting in high energy yields. Our multi-channel architecture allows for individual tracking of differently-oriented solar panels. We test and certify our technology according to automotive standards and specific use cases. For example, our MCU has achieved ECE R-10 certification and therefore complies with regulatory requirements for electromagnetic compatibility. Our MCU is able to communicate with controlled area networks (CAN), a standard communication protocol in the automotive industry that enables intelligent integrations in the vehicle architectures to perform clever tasks like preconditioning (heating/air-conditioning) a bus when a surplus of solar power is given. In addition, multiple MCUs can be connected to work with systems with higher power, such as eBuses and trailers.

We have focused on two variants of our MCU:

Following the further development of our high voltage MCU to support both 400V and 800V architectures, we recently adjusted our distribution strategy and increased our focus on high voltage solar solutions, in particular for OEM applications, with a goal to make solar integration a factory-installed feature, offering a scalable, high-efficiency solution for refrigerated trailers, electric buses and other use cases.

Principal Products and Services

Our product portfolio consists of solar integration solutions for commercial vehicles, leveraging our proprietary solar charge controller technology or MCU. Our offerings are designed to be as standardized as possible yet customizable to meet specific customer needs. We categorize our solutions into four key areas:

Complete Solar Solutions

We provide fully integrated solar systems tailored for refrigerated vehicles, buses, electric vans and other commercial vehicles. These solutions include:

While our primary focus is on refrigerated vehicles, buses and electric vans (including campers), our engineering expertise enables us to develop customized solutions for any commercial vehicle type upon request.

Solar Charge Controllers

Our portfolio of solar charge controllers is available as a standalone offering, allowing fleet operators and OEMs to integrate solar energy management into existing vehicle platforms. This portfolio includes:

Solar Modules

We offer our solar modules to our customers as stand-alone products, through third-party purchases and, potentially, through co-marketing partnerships. While complete solar solutions are our primary focus, we recognize that certain fleet operators may seek individual solar module components for their existing systems.

Data Services and Engineering Services

Beyond hardware, we provide advanced data solutions and engineering services, enabling seamless OEM adoption of solar technology. These include:

By combining our hardware expertise with engineering services, we enable seamless OEM adoption of solar technology, making solar-powered commercial transport a scalable reality.

Market Opportunity

For the solar application market, we believe that our solar technology is a solution to making combustion engine vehicles and BEVs more energy efficient. By integrating our solar technology, fleet operators can reduce energy consumption in a variety of commercial vehicles including, among others, buses, trailers, trucks, vans and refrigeration vehicles, and thereby significantly reduce the total cost of ownership.

In addition, sustainability goals continue to drive environmental regulations requiring vehicle manufacturers to meet increasingly stringent regulatory targets. For example, more and more municipalities have announced that they intend to set stringent emission targets for vehicles driving in their municipal area. Further, an increase in the number of BEVs may result in grid overload and destabilization.

The push for fleet electrification has also increased demand for energy-efficient solutions that extend range, improve operational efficiency and reduce reliance on charging infrastructure. Solar integration directly addresses these challenges by providing a supplementary, renewable energy source, reducing grid dependency for commercial vehicles operating in urban and remote areas. In parallel, we anticipate an increase in demand for sustainable energy solutions, driven by elevated energy prices and carbon taxation policies.

Other users, such as building owners, already experience the power and benefits of solar integration in reducing energy consumption and, accordingly, total cost of ownership. As more means of transportation, including ships, trucks, vans and buses, switch over to electric engines in the coming years, the benefit of solar integration will, we believe, become increasingly clear and important to market participants. Additionally, the commercial transport sector is experiencing growing regulatory pressure to meet net-zero emission targets, making solar energy an attractive, scalable complement to traditional vehicles and BEVs. In addition to using our technology for solar retrofitting, we also believe that solar integration will become an increasingly adopted feature in next-generation electric vehicles, particularly in the commercial and fleet sectors.

Solar production prices declined relatively consistently over the last ten years, with some marginal increases since the beginning of 2020 resulting partly from supply chain issues in connection with the global COVID-19 pandemic. The current advancements in solar manufacturing, combined with the increasing energy efficiency of solar cells, enable solar integration to have a meaningful impact on energy consumption, range extension and operational autonomy for electric vehicles. Additionally, the rapid expansion of electric vehicle sales and the comparatively slower increase in charging stations is expected to create a bottleneck for the adoption of electric fleets on a larger scale. We believe that, within the next few years, fleet operators and individual consumers in regions with limited charging infrastructure will be hesitant to adopt BEVs due to uncertainty as to whether they will be able to reliably access charging options.

In this context, solar-equipped commercial vehicles serve as a bridge between the traditional diesel-powered fleets of today and what we believe will be the fully electric future of tomorrow. While charging infrastructure continues to lag behind electric vehicle adoption rates, solar technology provides an immediate solution to reduce emissions and diesel consumption. By integrating solar into commercial transport, operators can achieve meaningful fuel savings and emissions reductions today, while preparing for the long-term transition to full electrification. This makes solar an enabler of cleaner mobility even before widespread charging networks become fully operational.

Solar-equipped vehicles thus offer a compelling solution, reducing reliance on public charging infrastructure and enabling extended off-grid operation, particularly for last-mile delivery, logistics and public transportation applications.

Research and Development

Our development strategy has focused on developing our key technologies and innovations in-house, where we benefit from the expertise of our highly-qualified development team. This has allowed us to ensure that the key technologies and innovations reflect our core values and vision of sustainable and affordable electric mobility. We have cooperated with renowned research institutions to combine our expertise in selected areas. For example, we have continued our participation in public funding projects and collaborations with renowned research institutes like Fraunhofer and Tecnalia.

Manufacturing and Supply Chain

We have employed a lean and capital-efficient approach to manufacturing, leveraging strategic supplier partnerships while maintaining full control over design, development and intellectual property. This model has been designed to optimize both costs and performance while ensuring scalability to meet increasing market demand.

Solar Module and Component Manufacturing

The semi-flexible solar modules used in our solar kits are supplied by selected vendors and partners that work closely with us throughout the development and production process to meet our technical and durability requirements.

MCU Production and Supply Chain

Our MCU is a key component of our energy management system and is produced externally based on our proprietary design and specifications. We work with selected manufacturing partners to ensure quality and scalability while maintaining flexibility in supplier selection and production footprint.

The MCU is designed for a streamlined build-to-print manufacturing process, supporting efficient scaling as demand increases. We retain full ownership of the design and core intellectual property, allowing us to control quality, maintain differentiation and adapt our production setup as needed.

Our manufacturing strategy is asset-light and enables responsive scaling without the need for significant upfront capital investment. This flexibility supports our evolving OEM collaborations and allows us to align production with market developments while maintaining cost efficiency and quality at the core.

Competitive Landscape    

While the market for solar technology solutions for all kinds of stationary applications is highly competitive, the competitive landscape for vehicle-integrated solar solutions remains relatively niche. Based on a survey conducted by our business intelligence team, we have identified a few competitors particularly relevant to us, including KRSolar B.V. (d/b/a wattlab), Im Efficiency B.V., Green Energy Solutions, OPES and TRAILAR, with regards to retrofit solutions like our solar kits, and SolarEdge E-Mobility and Victron Energy B.V., with regards to our solar power electronics, or MCU.

We believe that the following factors differentiate us and our products from these competitors:

Regulatory Environment for Our Legacy Solar Operations

Overview

Our industry and business operations are subject to various laws, rules and regulations at international, national, state and municipal levels, which may affect, directly or indirectly, our operations or our industry. Also taking into account the fact that our customers have primarily been fleet operators and automotive suppliers or manufacturers, such laws, rules and regulations include laws on vehicle approval and homologation, laws on vehicle road safety, environmental laws, laws on vehicle emissions and renewable energies, consumer protection laws, product warranty and product liability laws, intellectual property and copyright laws, labor and employment protection laws, export control regulations, trade and economic sanctions and embargoes on certain countries, persons, groups and/or entities, projects and/or activities, competition and antitrust laws, tax laws and criminal laws (e.g. anti-money laundering and anti-corruption laws). Within the EU, the legal environment is also characterized by a set of political initiatives and legal frameworks under the so-called European green deal, which seeks to serve the overarching goal of eliminating greenhouse gas emissions and reaching climate neutrality by 2050. These initiatives and legal frameworks have had and will continue to have a significant influence on our industry and business operations, as well as on the overall adoption rate of electric mobility within the EU.

An overview of the laws, rules and regulations that are or are expected to be most relevant for our business operations or industry, broken down by general category of regulation, is provided below. Any reference in this section to any legislation or regulation is deemed to refer to such legislation or regulation as amended, supplemented or otherwise modified, and all further rules and regulations promulgated thereunder, unless the context requires otherwise.

Vehicle Approval/Road Safety

Depending on the exact use of our products and solutions by customers, our solar modules and other solar technology solutions may be covered by compliance requirements applicable to these customer groups such as fleet operators and automotive suppliers and/or manufacturers under product-related regulatory frameworks and approval by the relevant government authorities. Vehicles and vehicle components are required to comply with substantial licensing, certification, approval, permit and other homologation requirements in all relevant markets in which they operate, as well as numerous and continually increasing technical product requirements.

General Product Safety Liability

Our solar modules and other solar technology solutions will also have to comply with product-specific or general, non-specific product safety and product liability legislation and associated regulations.

The EU has passed a directive on general product safety that applies in the absence of specific provisions among the EU regulations governing the safety of the products concerned or if legislation applicable to the sector is insufficient. Under this directive, manufacturers and distributors may only market products that comply with a general requirement of consumer safety. Taking into account certain points specified in the directive, a product is considered to be safe if, under normal or reasonably foreseeable conditions of use, it does not present any risk or only the minimum risks compatible with the product’s use, considered to be acceptable and consistent with a high level of protection for the safety and health of persons. In addition to compliance with the safety requirement, manufacturers and distributors must provide consumers with the information necessary to assess a product’s inherent risks and take the measures necessary to avoid such threats (for example, withdraw products from the market, inform consumers and recall products). Strict liability applies for defective products throughout the EU in addition to any consumer protections at the national level.

In Germany, the EU requirements have been implemented via the Product Safety Act (Produktsicherheitsgesetz) and the Product Liability Act (Produkthaftungsgesetz), which are accompanied by more general provisions under tort laws codified in the German Civil Code § 823 (Bürgerliches Gesetzbuch).

Vehicle Emissions and Regulatory Incentives

The protection of air quality and reduction of greenhouse gas emissions is a priority in the EU, and vehicle manufacturers relying on internal combustion engines must comply with increasingly stringent standards on vehicle emissions. The current environment of the EU and regulatory initiatives strongly support the development, production and sale of alternative fuel vehicles and their overall market adoption. In line with the international climate agreement signed at the 2015 United Nations Framework Convention on Climate Change in Paris by nearly 200 nations (commonly referred to as the “Paris Agreement”), which became effective in November 2016 and consists of two elements (a commitment by each participating country to set a voluntary emissions reduction target (referred to as “nationally determined contributions” or “NDCs”), with a review of the NDCs that could lead to updates and enhancements every five years beginning in 2023, and a transparency commitment requiring participating countries to disclose their progress), as well as based on emission legislation, the EU is taking a progressive stance in reducing carbon dioxide emissions, thereby deliberately driving increasing demand for electric vehicles.

Furthermore, the EU has implemented mandatory CO2 emissions targets. At present, all car manufacturers must meet a fleet-wide average emission target of 95g CO2/km for their new passenger vehicles that are registered in the EU. Light commercial vehicles are subject to an EU fleet-wide target of 147g CO2/KM for average emissions. Car manufacturers are given additional incentives to produce zero- or low-emission cars emitting less than 50g CO2/km through a fleet-wide credits system. The regulation also provides for fleet-wide average CO2/km emissions targets for the years 2025, 2030 and 2035, which are defined as a percentage reduction from the current applicable values: cars are subject to fleet-wide CO2 reductions of 15% in 2025, 55% in 2030 and 100% in 2035, while vans are subject to fleet-wide reductions of 15% in 2025, 50% in 2030 and 100% in 2035. The regulation also allows for pooling arrangements among several manufacturers of passenger cars or vans, based on which these manufacturers will be treated as a single “pool” and their compliance with emission limits will be assessed on an aggregated basis at the pool level. Car manufacturers are subject to penalty payments if a car manufacturer’s fleet-wide average emission of CO2/km exceeds the defined target values in a given year. The monetary penalty is calculated based on a predetermined euro amount (currently €95) for each gram of CO2/km that exceeds the relevant target value multiplied by the number of vehicles produced by the car manufacturer.

The adoption of electric mobility is further promoted on the national level within the EU. The vast majority of member states of the EU provide purchase grants, tax benefits or other incentive schemes to buyers of electric vehicles.

Renewable Energy Requirements

The laws and regulations within the EU and various other jurisdictions impose energy source requirements for the transportation sector, which also aim to reduce the emission of greenhouse gases and promote the adoption of alternative fuel or electric vehicles. A directive adopted in 2018, and amended in 2023, establishes a common system for the promotion of energy from renewable sources (such as wind, solar (both solar thermal and solar solar) and geothermal energy, tide, wave and other ocean energy, hydropower or biomass) in electricity, heating and cooling and transport and provides a framework for the promotion of the use of renewable energy sources in the EU until 2030. The directive defines a binding overall target of at least 42.5% of energy from renewable sources for the EU’s gross final energy consumption by 2030 (calculated as the sum of the member states’ gross final consumption of electricity and energy in various sectors) and promotes the use of renewable energy in transport, particularly prioritizing electricity, with a target of at least 29% renewables in the final energy consumption mix by 2030 or a greenhouse gas intensity reduction of at least 14.5% by 2030. The directive envisages electric mobility to constitute a substantial part of the renewable energy mix in the transport sector by the year 2030 and is a cornerstone for the adoption and integration of electric mobility within the EU, as it also supports incentive schemes for the swift development of electric mobility with respect to the sector’s growth potential and role for the EU employment market. In addition, the directive seeks to boost the use of renewable electricity in the transport sector by applying augmented multipliers in the context of the calculation of the relevant energy mix under the directive.

Industrial Environmental Control

All member states of the EU control the manufacture, use and disposal of pollutants by means of regulations on air pollutants, chemicals, heavy metals, persistent organic pollutants, soil contamination and biocides. The operations of manufacturers, particularly production, logistics and transport processes, as well as end products, must comply with these regulations.

The most relevant legal frameworks are the Regulation for Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”) and the Regulation on Classification, Labeling and Packaging of Substances and Mixtures (“CLP”). REACH requires manufacturers and importers of chemicals to identify and manage risks linked to the substances they manufacture and market. Companies need to register substances placed on the market in the EU in quantities of one tonne or more a year, and the type of information required for registration will depend on the amount manufactured or imported in the EU. There are information sharing obligations for different actors in the supply chain to ensure proper application and use of such substances. In addition, substances which are considered hazardous could be subject to authorization or restrictions in the future, any of which may delay or increase the costs of operations if there is a need to obtain authorization or find an alternative substance. CLP complements REACH by requiring suppliers of substances and mixtures, including manufacturers, downstream users and distributors, to apply harmonized criteria to their classification and labeling.

Substance restrictions under REACH in some cases prohibit the marketing in the EU of articles containing certain substances. This is particularly relevant in relation to spare parts for products, which were designed before a relevant restriction was adopted and which are no longer in mass production (“legacy parts”). Similar problems may arise if a substance is placed under an authorization requirement under REACH and may, therefore, not be used for the production of legacy parts without a corresponding authorization. REACH does not include general exemptions with regard to legacy parts (so-called “repair as produced” clauses).

Emissions from Production

Emissions from production, such as air pollutants, noise, odors, vibrations and greenhouse gasses (such as CO2), are governed by specific laws and regulations, and, if the operation of a facility is subject to a permit, by specific conditions set forth therein. Some laws and regulations require the submission of emission reports on a regular basis. Non-compliance with maximum emission levels may result in administrative fines.

International, as well as European and national regulations, may have repercussions on the operation of the relevant production facilities. For example, stricter regulation of CO2 emissions could cause manufacturers to incur significant capital expenditures to upgrade production plants by installing or improving technical equipment to comply with maximum emission levels that may become applicable in the future, which may also affect their ability to sell their products at predetermined price levels.

Emission trading systems for emissions from industrial production exist on the European and national level. These systems are based on “cap and trade” principles designed to reduce carbon dioxide emissions by limiting the number of emission allowances (cap) required for certain facilities and allowing the purchase for shortfall or the sale of surplus emission allowances (trade). A new EU Carbon Border Adjustment Mechanism (“CBAM”) is being introduced gradually for imports of certain goods such as steel, iron, electricity and fertilizers seen as at most significant risk of carbon leakage. CBAM will ensure the carbon price of imports is equivalent to the carbon price of domestic production to avoid any undermining of the EU’s climate objectives. Importers of in-scope goods are required, during this transitional period, to submit reports on direct and indirect greenhouse gas emissions; however, overtime the obligations will increase and require “CBAM certificates” to be purchased. It is intended that CBAM will extend to other sectors from 2026. The gradual introduction of CBAM is aligned with the phase-out of the allocation of free allowances under the EU Emissions Trading System (ETS) to support the decarbonization of EU industry.

Reuse, Recycling and Recovery

Manufacturers may also be obligated to assist customers with the disposal, recovery and recycling of certain underlying components of their products once they have reached their end- of-life/disposal stage.

An EU directive on batteries (the “Batteries Directive”) governs the recovery of batteries within the EU. The Batteries Directive requires manufacturers and distributors of batteries to bear a significant amount of the costs associated with proper collection and disposal of end-of-life batteries.

The new EU regulation on batteries (the “Batteries Regulation”) repealed and replaced the Batteries Directive on August 18, 2025. The Batteries Regulation aims to ensure that batteries have a low carbon footprint, use minimal harmful substances, need less raw materials from non-EU countries, and are collected, reused and recycled to a high degree in Europe. Targets for recycling efficiency, material recovery and recycled content will be introduced gradually from 2025 onwards. All collected waste batteries will have to be recycled and high levels of recovery will have to be achieved, in particular of critical raw materials such as cobalt, lithium and nickel. In addition, under the new law’s due diligence obligations, companies must identify, prevent and address social and environmental risks linked to the sourcing, processing and trading of raw materials such as lithium, cobalt, nickel and natural graphite contained in their batteries.

Furthermore, an EU directive on end-of-life vehicles (the “ELV Directive”) and an EU directive on waste from electrical and electronic equipment (the “WEEE Directive”) each govern the recovery of motor vehicles and electrical and electronic equipment within the EU, providing for ambitious recovery, reuse and recycling rates. The directives require that manufacturers cover all, or a significant part, of the costs associated with recovery, reuse and recycling measures. The aforementioned directives, including the Batteries Directive, as well as an EU directive on the restrictions of the use of certain hazardous substances in electrical and electronic equipment and the Batteries Regulation, limit manufacturing options because they also contain prohibitions on the use of certain identified substances and materials. The Batteries Regulation also introduces performance classes and maximum limits on the carbon footprint of electric vehicles.

Cross-border Import and Export of Products

Sales of our products and solutions have been subject to trade policy measures, such as tariffs.    

Within our primary target market, the EU’s internal market, the principle of free movement of goods applies. When importing goods from, and exporting goods to, non-EU countries, we have had to comply with national and European foreign trade and customs regulations.

Various countries impose tariffs on products and/or materials imported from other jurisdictions. Any tariffs imposed in markets where we market and sell our solar solutions affect the prices of our products and negatively impact our sales and ability to compete in those markets.

Data Protection and Privacy

The GDPR applies to the processing of personal data in the context of activities of establishments in the European Economic Area (“EEA”), regardless of whether the processing takes place in the EEA or not. The GDPR and other data privacy laws regulate when and how personal data may be collected, for which purposes it may be processed, for how long such data may be stored and to whom and how it may be transferred. The GDPR contains strict requirements for obtaining the consent of data subjects (i.e., the persons to whom personal data relates) to the use and processing of their personal data. The GDPR also requires the implementation of appropriate technical and organizational measures, depending on the nature of the processing activities. It also imposes various obligations in the context of processing of data, including, among others, far-reaching transparency, data minimization, storage limitations, privacy by design and privacy by default obligations, data security, integrity and confidentiality obligations. In addition, it may require so-called data protection impact assessments, at least in cases where the data processing is likely to result in a high risk to the rights and freedoms of individuals. In Germany, operators of online platforms have to comply with the specific requirements of the German Tele Media Act (Telemediengesetz), which takes into consideration particular aspects of online communication. For example, the German Tele Media Act provides for additional information obligations which are stricter than the general requirements of the Data Protection Act (e.g., a requirement to include an imprint on websites and apps).

An EU directive on the processing of personal data and the protection of personal data in the electronic communications sector adopted in 2002 sets out rules to ensure security in the processing of personal data, the notification of personal data breaches and confidentiality of communications through public electronic communication services such as the internet and mobile telephony. Providers of such electronic communication services must, among others, ensure that personal data are accessed by authorized persons only, are protected from being destroyed, lost or accidentally altered and from other unlawful or unauthorized forms of processing and ensure the implementation of a security policy on the processing of personal data. The e-Privacy Directive also contains several provisions aimed at ensuring the confidentiality of electronic communications and sets forth strict (consent) requirements for the use of cookies and for unsolicited communication as part of direct marketing efforts. The e-Privacy Directive has been implemented in the Netherlands by the Dutch Telecommunications Act (Telecommunicatiewet) and in Germany by the German Telecommunications Act (Telekommunikationsgesetz). On January 10, 2017, the European Commission released a proposal for a regulation of the European Parliament and of the Council of the EU concerning the respect for private life and the protection of personal data in electronic communications (the e-Privacy Regulation), which would repeal the e-Privacy Directive. The proposal is still subject to legislative procedure and debate.

In March 2021, the United Nations announced UN R155 – a regulation on cybersecurity and cybersecurity management systems. The regulation requires that, from July 2022, all new vehicle types and, from July 2024, all registered vehicles must prove that their product development is based on a systematic approach to risks associated with cyber threats to their cars. The regulations have been adopted by the EU as well as jurisdictions such as Japan and South Korea. The UN regulations are not expected to be adopted in the United States or China where similar regulations are expected to be adopted.

Antitrust Law

Competition and antitrust laws and regulations are designed to preserve free and open competition in the marketplace to enhance competitiveness and economic efficiency. Provisions on merger control, the prohibition of anticompetitive agreements, collusive behavior, the prohibition of abuse of a dominant position and the receipt of advantages in violation of state aid rules within the market are of particular relevance for manufacturers. National and supranational competition and antitrust authorities may initiate investigations and proceedings for alleged infringements of competition or antitrust laws, which may result in significant fines or other forms of liability or impose certain limitations or conditions regarding acquisitions and certain business practices.

Within the EU, compliance with applicable European and national competition laws is monitored by the European Commission and in some cases the national competition authorities. The EU’s antitrust rules are set out in Articles 101 and 102 of the Treaty on the Functioning of the European Union (“TFEU”). Article 101(1) of the TFEU prohibits anticompetitive agreements to the extent they are not otherwise exempted by Article 101(3) of the TFEU. Article 102 TFEU prohibits the abuse of a dominant position. Article 107 (1) TFEU prohibits the granting of state aid.

Class Actions to Enforce Regulations

In the EU and certain of its member states, there is or has been an increasing prevalence of legislation governing class actions and their use to enforce regulations. As a result of these developments, consumers have increasingly powerful legal mechanisms at their disposal to collectively sue manufacturers of consumer products.

In the EU, under the banner of “A New Deal for Consumers,” the European Commission is facilitating a trend towards the increasing availability and use of collective redress mechanisms in areas in which EU law grants rights, including in particular consumer protection rules and regulations. The European Commission made a non-binding recommendation for EU member states to adopt collective redress procedures in June 2013, subsequently consulted on progress in 2017 and published a report on the subject in January 2018. A proposal for a new directive regarding “better enforcement and modernization of EU consumer protection rules” has been put forward by the European Commission. EU member states have also been developing their own rules in this regard. In Germany a law introducing a declaratory model action (Musterfeststellungsklage) came into force on November 1, 2018. With this new declaratory model action, certain persons are entitled to seek a legal declaration concerning factual or legal matters regarding consumer claims. Consumers can then opt in to be bound by a judgment (and under certain circumstances also a settlement) issued in the declaratory model proceedings.

In the Netherlands, in the event a third party is liable to a Dutch company, as a general principle only the company itself can bring a civil action against that party. The individual shareholders do not have a general right to bring an action on behalf of the company. However, in the event that the cause for the liability of a third party to the company also constitutes a tortious act directly against a shareholder, that shareholder may have an individual right of action against such third party in its own name. Dutch law provides for the possibility to initiate such actions collectively, in which a foundation or an association can act as a class representative and has standing to commence proceedings and claim damages if certain criteria are met. The court will first determine if those criteria are met. If so, the case will go forward as a class action on the merits after a period allowing class members to opt out from the case has lapsed. All members of the class who are residents of the Netherlands and who did not opt out will be bound to the outcome of the case. Residents of other countries must actively opt in in order to be able to benefit from the class action. The defendant is not required to file defenses on the merits prior to the merits phase having commenced. It is possible for the parties to reach a settlement during the merits phase. Such a settlement can be approved by the court, which approval will then bind the members of the class, subject to a second opt-out. This regime applies to claims brought after January 1, 2020 and which relate to certain events that occurred prior to that date. For other matters, the old Dutch class actions regime will apply. Under the old regime, no monetary damages can be sought. Also, a judgment rendered under the old regime will not bind individual class members. Even though Dutch law does not provide for derivative suits, directors and officers can still be subject to liability under U.S. securities laws.

Regulatory Environment for Our Digital Asset Treasury Strategy

Subsequent to December 31, 2025, we adopted the Treasury Strategy. Under the Treasury Strategy, we intend to use the net proceeds from our recent financings to purchase or otherwise acquire Bitcoin (BTC) and other digital assets and to establish digital asset treasury operations.

The regulatory regime for digital assets in the U.S. and elsewhere is uncertain. There is ongoing scrutiny and limited formal guidance from regulatory agencies, including Nasdaq and the SEC, with respect to the treatment of public company cryptocurrency strategies. If regulatory changes or interpretations require us to register as a money services business with The Financial Crimes Enforcement Network (FinCEN) under the U.S. Bank Secrecy Act, or as a money transmitter under state laws, we may be subject to extensive regulatory requirements, resulting in significant compliance costs and operational burdens. In such a case, we may incur extraordinary expenses to meet these requirements or, alternatively, may determine that continued operations are not viable. If we decide to cease certain operations in response to new regulatory obligations, such actions could occur at a time that is unfavorable to investors.

The U.S. federal government, states, regulatory agencies, and foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of BTC or the ability of individuals or institutions such as us to own or transfer BTC and utilize blockchain-based applications on networks such as Bitcoin. For example, the U.S. executive branch, the SEC, the European Union’s Markets in Crypto Assets Regulation, among others, have been active in recent years, and in the United Kingdom, the Financial Services and Markets Act 2023 became law. Additionally, legislative and regulatory priorities may change depending on changes in leadership, as evidenced by recent and proposed initiatives such as the Genius Act of 2025, the anticipated Digital Asset Market Clarity Act, and updates to the Commission’s Regulatory Flexibility Agenda. It is not possible to predict whether, or when, any of these developments will lead to Congress granting additional authorities to the SEC, Commodity Futures Trading Commission (“CFTC”), or other regulators, or whether, or when, any other federal, state or foreign legislative bodies will take any similar actions. It is also not possible to predict the nature of any such additional authorities, how additional legislation or regulatory oversight might impact the ability of digital asset markets to function or the willingness of financial and other institutions to continue to provide services to the digital assets industry, nor how any new regulations or changes to existing regulations might impact the value of digital assets generally and BTC specifically.

Competitive Landscape for Our Digital Asset Treasury Strategy

As a result of our Bitcoin-focused strategy, we expect our assets to be concentrated in BTC holdings. There are numerous alternative digital assets and many entities, including consortiums and financial institutions, are researching and investing resources into private or permissioned blockchain platforms. In addition, digital assets other than BTC, including those with significant private or public sector backing, including by governments, consortiums or financial institutions, may emerge or grow in popularity. If the mechanisms or network effects on alternative blockchain platforms are perceived as superior to the Bitcoin network, those digital assets could gain market share relative to Bitcoin. The intended concentration of our BTC holdings limits the risk mitigation that we could achieve if we were to purchase a more diversified portfolio of treasury assets.

See the section herein entitled “Risk Factors”.

Intellectual Property

Our intellectual property, including trade secrets, patents, trademarks and copyrights, is important to our business. We hold several patents in different jurisdictions relating to our solar module technology, ventilation system and energy management system for vehicles, and have filed several patent applications, including relating to our solar technology. We have registered trademarks in the EU or other relevant jurisdictions for “Sono Motors”. Our intellectual property portfolio includes domain names for websites that we use in our business.

We control access to, use of and distribution of our intellectual property through confidentiality procedures, non-disclosure agreements with third parties and our employment and contractor agreements. Under the German Employee Invention Act (Arbeitnehmererfindungsgesetz), we generally have a claim on work-related inventions by our employees. In addition, we rely on contractual provisions with our business partners to protect our intellectual property and proprietary technology, brand and creative assets. We seek to maintain and protect our intellectual property portfolio, including by pursuing any infringements by third parties.

The following graphic provides an overview of our granted patents and filed patent applications as of March 25, 2026:

(1) Patent Cooperation Treaty – the international patent system

(2) Vehicle integrated photovoltaic

(3) Solar electric vehicle systems

Our patent portfolio, held at the Subsidiary level, currently comprises 26 patent families (i.e., independent inventions), which include 9 granted patents, 3 PCT applications, 28 non-PCT national or EP applications and 3 utility models.

The content of the patent families can be categorized by vehicle integrated photovoltaic components or manufacturing processes, solar electric vehicle systems, solar charge converters and Sion-related non-PV inventions, which are reflected in the above graphic as ViPV, SEV, MCU and Sion-only, respectively. As presented above, most of the applications are related to ViPV and SEV.

Human Capital Resources

As of March 25, 2026, the Subsidiary employs 23 individuals, of which 15 are full-time employees across engineering, product development, business operations and corporate functions. In addition, although the Company currently has no employees, we do have consulting arrangements with our two executive officers. In line with our streamlined operational approach and strategic focus on key partnerships, the Subsidiary has over the last year implemented a reduction in workforce. There may be further reductions in its workforce as a result of the termination by the Company of all current and future funding commitments to the Subsidiary and the decision to exit the legacy solar operations conducted through the Subsidiary.

Corporation Information

Corporate History

We have historically conducted our business through the Subsidiary, which became a wholly-owned subsidiary of the Company after a corporate reorganization described as follows: We were incorporated pursuant to the laws of the Netherlands as Sono Motors Finance B.V. on October 23, 2020 as a wholly-owned subsidiary of the Subsidiary. As part of the corporate reorganization that was completed on November 27, 2020, the Subsidiary’s then-existing shareholders contributed all of their shares in the Subsidiary to Sono Motors Finance B.V. in exchange for newly issued ordinary shares of Sono Motors Finance B.V. In addition, the sole issued and outstanding common share in Sono Motors Finance B.V. at that time, which was held by the Subsidiary, was canceled (ingetrokken). As a result, the Subsidiary became a wholly-owned subsidiary of Sono Motors Finance B.V. and the then-existing shareholders of the Subsidiary became the shareholders of Sono Motors Finance B.V. Also on November 27, 2020, Sono Motors Finance B.V. was converted into a public company with limited liability under Dutch law (naamloze vennootschap), and changed its legal name from Sono Motors Finance B.V. to Sono Group N.V. The Company is incorporated in the Netherlands and our business address is Waldmeisterstraße 93, 80935 Munich, Germany.

On September 4, 2025, the Company received notice from the Nasdaq Stock Market LLC (“Nasdaq”) that our Ordinary Shares have been approved for listing on Nasdaq. The Ordinary Shares commenced trading on Nasdaq Capital Market on September 5, 2025 under the ticker symbol “SSM”.

Following our initial public offering (our “IPO”) in November 2021, our Ordinary Shares were traded on the Nasdaq Global Market under the symbol “SEV”. On July 12, 2023 and August 28, 2023, we received notices from Nasdaq stating that the staff of the Listing Qualifications Department (the “Staff”) had determined that our Ordinary Shares will be delisted from the Nasdaq Global Market in accordance with Nasdaq’s Listing Rules and notifying us of the suspension in trading of our Ordinary Shares as of the opening of business on July 21, 2023. Following our appeal of the Staff’s determination, we received a decision of the Nasdaq Hearings Panel (the “Panel”) on December 11, 2023, advising us that the Panel had determined to delist our Ordinary Shares from Nasdaq. On February 15, 2024, Nasdaq filed a Form 25 Notification of Delisting with the SEC to complete the delisting. As a result, on July 2, 2024, our Ordinary Shares commenced quoting on the OTCQB under the ticker symbol “SEVCF.” Following the Reverse Share Split (as defined below), we successfully pursued the uplisting of our Ordinary Shares to the Nasdaq Capital Market as described above. There is no assurance, however, that we will be able to satisfy the continued listing requirements of the Nasdaq Capital Market. See “Risk Factors—Risks Related to Our Securities—Following the listing of our Ordinary Shares on the Nasdaq Capital Market in September 2025, we may not be able to meet the continuing listing requirements of the Nasdaq Capital Market and therefore may not be able to have our Ordinary Shares traded on Nasdaq or other national stock exchange in the future”.

On December 23, 2024, the Company amended its articles of association to implement a reverse share split (the “Reverse Share Split”) of our Ordinary Shares and high voting shares (the “High Voting Shares”) at a ratio of 1-for-75. The Reverse Share Split was previously approved by the Company’s shareholders at the extraordinary general meeting of the Company held on January 31, 2024 (the “January 2024 EGM”). The Reverse Share Split took market effect on January 6, 2025, following confirmation from the Financial Industry Regulatory Authority (“FINRA”) that it had received and reviewed all necessary documentation to process the Reverse Share Split.

The Former Self-Administration Proceedings, the Yorkville Restructuring Investment and the Yorkville Commitment

On May 15, 2023, based on management’s conclusion that the Company was over-indebted and faced impending illiquidity (drohende Zahlungsunfähigkeit), the Company applied to the insolvency court of the local court of Munich, Germany (the “Court”), to permit the opening of a self-administration proceeding (Eigenverwaltung) with respect to the Company pursuant to Section 270 (b) of the German Insolvency Code (Insolvenzordnung). On the same day and for the same reason, the Subsidiary applied to the Court to permit the opening of a self-administration proceeding in the form of a protective shield proceeding (Schutzschirmverfahren) with respect to the Subsidiary pursuant Section 270 (d) of the German Insolvency Code (collectively, the “Self-Administration Proceedings”). On May 17, 2023 and May 19, 2023, the Court admitted the opening of Self-Administration Proceedings on a preliminary basis (the “Preliminary Self-Administration Proceedings”) with respect to the Company and the Subsidiary, respectively. On September 1, 2023, the Court opened the Self-Administration Proceedings with respect to the Subsidiary (the “Subsidiary Self-Administration Proceedings”). On January 31, 2024, the Subsidiary withdrew its application for Preliminary Self-Administration Proceedings. The Subsidiary exited its Self-Administration Proceedings on February 29, 2024 via its plan under the German Insolvency Code (the “Plan”), which set out how the Subsidiary intended to restructure its debt and procure the inflow of new cash, including pursuant to a funding commitment from Yorkville in the form of the Yorkville Restructuring Investment (as defined herein).

In mid-November 2023, in the context of the former Self-Administration Proceedings, the Company and Yorkville entered into certain investment-related agreements that became effective on November 20, 2023 (such agreements collectively, the “Yorkville Investment Agreements”), pursuant to which Yorkville committed to provide financing to the Company, subject to the Companies’ continued compliance with the terms of the Yorkville Investment Agreements. Among other Yorkville Investment Agreements, the Company and Yorkville entered into a restructuring agreement (as amended from time to time, the “Restructuring Agreement”) and a funding commitment letter (as amended from time to time, the “Funding Commitment Letter”), pursuant to which Yorkville committed to provide limited financing to the Company (the “First Commitment”). On April 30, 2024, the Company and Yorkville entered into an amendment to the Funding Commitment Letter, pursuant to which Yorkville committed additional financing to the Company (the “Second Commitment” and together with the First Commitment, the “Yorkville Restructuring Investment”). The funding of the first tranche of the Yorkville Restructuring Investment (the “First Tranche”) occurred on February 6, 2024 for approximately $4.3 million and the funding of the second tranche of the Yorkville Restructuring Investment (the “Second Tranche”) took place on August 30, 2024 for approximately $3.3 million. For more information on the Yorkville Restructuring Investment and the transactions contemplated and entered into in connection therewith, see “Item 1. Business—Financing Arrangements with Yorkville—The Yorkville Restructuring Investment”.

On December 30, 2024, the Company and Yorkville committed to a new financing arrangement and entered into the Securities Purchase Agreement, pursuant to which Yorkville committed to provide limited financing to the Company in the amount of $5 million (the “Yorkville Commitment”), subject to certain conditions and limitations, including the Company’s receipt of notice from Nasdaq that the Company has met all the applicable requirements for listing of the Ordinary Shares on the Nasdaq Capital Market. On February 12, 2025, the Company and Yorkville amended the Securities Purchase Agreement by way of the First Omnibus Amendment (as defined herein), which provided for, among other things, an immediate advance of $1,000,000 of the Yorkville Commitment in the form of the First Debenture (as defined herein). The commitments made by Yorkville in the Securities Purchase Agreement and the First Omnibus Amendment effectively satisfy any and all obligations of the Investor to provide additional funding to the Company under the Funding Commitment Letter. Subsequently, on March 25, 2025, pursuant to the Third Omnibus Amendment (as defined herein), Yorkville provided a second immediate advance of $1,000,000 in the form of the Second Debenture (as defined herein). On April 24, 2025, pursuant to the Fourth Omnibus Amendment (as defined herein), Yorkville provided a third immediate advance of $500,000 in the form of the Third Debenture (as defined herein). On May 26, 2025, pursuant to the Fifth Omnibus Amendment (as defined herein), Yorkville provided a fourth immediate advance of $750,000 in the form of the Fourth Debenture (as defined herein). On August 6, 2025, pursuant to the Eighth Omnibus Amendment (as defined herein), Yorkville provided a fifth immediate advance of $190,000 in the form of the Fifth Debenture (as defined herein). On August 15, 2025, pursuant to the Ninth Omnibus Amendment (as defined herein), Yorkville provided a sixth immediate advance of $350,540 in the form of the Sixth Debenture (as defined herein). On September 5, 2025, pursuant to the Tenth Omnibus Amendment (as defined herein), the Company and Yorkville agreed to, among other things, to (1) increase the aggregate principal amount of the New Convertible Debenture (as defined herein) by an additional $2,200,000 for a total of $7,200,000, (2) provide for an immediate advance by Yorkville to the Company of $3,409,460 in the form of the Seventh Debenture (as defined herein). On September 5, 2025, pursuant to an Exchange Agreement, as amended, and as a result of the receipt of notice from Nasdaq that the Company has met all the applicable requirements for listing of the Ordinary Shares on the Nasdaq Capital Market on September 4, 2025, the Company issued 1,401 Preferred Shares to Yorkville solely in exchange for the surrender and cancellation of all of the debentures held by Yorkville, including the 2022 Debentures (as defined herein), the new convertible debentures issued to Yorkville on February 5, 2024 and August 30, 2024 (the “2024 Debentures”), the Seventh Debenture and all of the other Advance Debentures (as defined herein). The Preferred Shares are convertible into Ordinary Shares at 85% of the lowest daily volume weighted average price of the Ordinary Shares during the 10 consecutive trading days immediately preceding the conversion date. As part of the commitment, Yorkville has agreed to a conversion price floor of $4.00 for six months and $1.00 thereafter. For more information on the Yorkville Commitment, see “Item 1. Business—Financing Arrangements with Yorkville—The Yorkville Commitment”.

Financing Arrangements with Yorkville

The Yorkville Restructuring Investment

In mid-November 2023, in the context of the former Self-Administration Proceedings and in connection with the First Commitment, the Companies and Yorkville entered into the Yorkville Investment Agreements. In addition to the Restructuring Agreement between the Company and Yorkville, which was amended on February 2, 2024 and February 5, 2024, the agreements included (i) an agreement between the Company and the Subsidiary pursuant to which a settlement amount was agreed for intercompany claims (the “Settlement Agreement”), (ii) an agreement between the Company and the Subsidiary relating to the satisfaction of intercompany claims, the further financing of the Subsidiary by the Company and key aspects of the Subsidiary Self-Administration Proceedings and the Plan (the “Continuation Agreement”), (iii) the Funding Commitment Letter, as subsequently amended, between the Company and Yorkville pursuant to which Yorkville committed to provide the Company with sufficient financial resources to fund the business operations of the Companies pursuant to an agreed upon budget, (iv) an agreement between the Company and Yorkville to postpone the repayment date of the convertible debentures with an aggregate principal amount of $31.1 million issued by the Company to Yorkville in December 2022 (the “2022 Debentures”) to July 1, 2025, with the possibility of further extensions at Yorkville’s discretion (the “Prolongation Agreement”), (v) an agreement between the Sono Group founders, Laurin Hahn and Jona Christians (the “Founders”), the Company and the Subsidiary pursuant to which the Companies were entitled to request that each of the Founders enters into a share sale and transfer agreement (the “Sale and Transfer Agreements”) under the terms of which the respective Founder would sell and transfer, if so requested, a portion of their Ordinary Shares to a trustee to be appointed for the benefit of the Subsidiary’s creditors and a portion of their Ordinary Shares and all of their High Voting Shares to the new members of the management board to be appointed for the Company (the “Shareholders Commitment Letter”), (vi) Sale and Transfer Agreements executed by each of the Founders to carry out the transfers contemplated in the Shareholders Commitment Letter, and (vii) a back-to-back letter of comfort from the Company to the Subsidiary, which was subsequently amended on May 8, 2024, to provide funding for the Subsidiary’s business operations, with an initial focus on the Solar Bus Kit and similar retrofit solar products (as amended from time to time, the “Back-to-Back Letter of Comfort”). The funds provided under the Back-to-Back Letter of Comfort were provided by way of intercompany loans.

Pursuant to the Yorkville Investment Agreements and following the satisfaction of certain conditions precedent, Yorkville funded the First Tranche of €4.0 million, or approximately USD 4.3 million, on February 6, 2024. On August 30, 2024, Yorkville funded the Second Tranche of €3.0 million, or approximately USD 3.3 million. Under the terms of the Funding Commitment Letter, Yorkville had committed to secure the financing of the Companies’ expected operational costs through the end of the second quarter of 2025, with financings being provided by way of new interest-bearing convertible debentures. The Company issued the 2024 Debentures to Yorkville on February 5, 2024 and August 30, 2024, with maturity dates of July 1, 2025 and August 20, 2025, respectively, in connection with the fundings of the First Tranche and Second Tranche. On December 30, 2024, the Company and Yorkville committed to a new financing arrangement in the form of the Yorkville Commitment that replaces, and satisfies, Yorkville’s remaining obligations under the Funding Commitment Letter. The advance fundings from Yorkville in 2025 in the form of the Advance Debentures were provided in full in connection with the new funding arrangement, as amended. For more information on the Yorkville Commitment, see “Item 1. Business—Financing Arrangements with Yorkville—The Yorkville Commitment”.

In accordance with the Settlement Agreement, the Company transferred or will transfer funds to the Trustee (as defined herein) in settlement of the intercompany claims owed by the Company to the Subsidiary. In turn, the Subsidiary waived all claims that the Subsidiary had or may have against the Company arising from intercompany claims or from either of two hard comfort letters issued by the Company for the benefit of the Subsidiary. Payment of the settlement amount, as well as payments of funds that belong to the Company’s creditors are ultimately processed by Bambino 255. V V UG, an entity established to serve as a trustee for the benefit of the Subsidiary’s creditors (the “Trustee”).

Under the Yorkville Investment Agreements, starting December 1, 2023, the Subsidiary became obligated to finance its business operations in accordance with the budget agreed with Yorkville. Following the satisfaction of the closing conditions set forth in the Yorkville Investment Agreements (the “Closing”), (i) Yorkville became obligated to pay the First Tranche to the Company at the Closing, (ii) the Company became obligated to reimburse the Subsidiary’s insolvency estate for the continuation costs incurred for the period from December 1, 2023 to the date of Closing and (iii) the Company became obligated to finance the business operations of the Subsidiary until the end of the fiscal year 2024, both in accordance with the budget agreed with Yorkville. Pursuant to the terms of the Back-to-Back Letter of Comfort, the Company became obligated to provide funds to the Subsidiary (subject to the availability of such funds at the Company level) of up to approximately €7.2 million by way of intercompany loan(s). The first funding under the Back-to-Back Letter of Comfort occurred immediately after Closing and amounted to €3.0 million. Subsequent funding under the Back-to-Back Letter of Comfort amounting to €1.0 million, €2.2 million, €300,000 and €420,000 were made on May 23, 2024, September 2, 2024, February 12, 2025 and March 25, 2025, respectively. These intercompany loans became secured loans to the Subsidiary during 2024 as the Subsidiary entered into a cross guarantee with Yorkville, pursuant to which Yorkville became the beneficiary of the amounts loaned to the Subsidiary by the Company.

In connection with the Yorkville Restructuring Investment, the Founders entered into respective Sale and Transfer Agreements, pursuant to which they agreed to cumulatively transfer 177,417 Ordinary Shares to the Trustee. The transfer of the Ordinary Shares to the Trustee was reflected in the Company’s share register on June 5, 2024. Following expiration of a lock-up agreement, the Trustee is now entitled to sell its shares, subject to certain volume restrictions agreed with Yorkville, and the proceeds from any such sales will be used to satisfy claims of the Subsidiary’s creditors. Whether and to what extent such sale proceeds can be realized will depend on a number of factors, including, among others, the performance of the Company's share price. Currently, it is not possible to reliably forecast whether and to what extent such sale proceeds can be expected. In addition, under the terms of their respective Sale and Transfer Agreements, the Founders agreed to cumulatively transfer 230,751 Ordinary Shares and all of their cumulative 40,000 High Voting Shares to SVSE LLC, a Delaware limited liability company (“SVSE”), whose sole member is George O’Leary, the Company’s Chief Executive Officer and sole Managing Director. The transfers of the High Voting Shares and the Ordinary Shares to SVSE were reflected in the Company’s share register on February 1, 2024 and March 25, 2024, respectively.

Under the terms of the Yorkville Investment Agreements, cash available to the Subsidiary and the proceeds from any sale of the Subsidiary’s assets that do not belong to the Subsidiary’s third-party vehicle solar integration business, including any proceeds from a future sale of the Sion program, may be used to cover the costs of the Subsidiary Self-Administration Proceedings and to satisfy claims of the Subsidiary’s creditors.

In accordance with the Yorkville Investment Agreements, the Company convened its annual general meeting on December 29, 2023 (the “2023 AGM”), as well as the January 2024 EGM, to submit certain agenda items for shareholder votes. Pursuant to the terms of the Shareholders Commitment Letter, each Founder in his respective capacity as a shareholder of the Company, either in person or represented by proxy, exercised the voting rights on all the shares in the capital of the Company held by such Founder in favor of all proposed resolutions at both the 2023 AGM and the January 2024 EGM. The following agenda items, among others, were proposed and approved at the January 2024 EGM: (1) a proposal to effect a reverse share split of the Ordinary Shares and the High Voting Shares at an exchange ratio to be determined and established by the Company’s management board; (2) a proposal to reduce the nominal value per Ordinary Share to €0.01 per Ordinary Share (after giving full effect to the aforementioned reverse share split) without repayment or any other payment by the Company to the shareholders; (3) a proposal to reduce the nominal value per High Voting Share to €0.25 per High Voting Share (after giving full effect to the aforementioned reverse share split) without repayment or any other payment by the Company to shareholders; and (4) a proposal to authorize one or more amendments to the Company’s articles of association, in such a manner that, with each amendment, the authorized capital of the Company is amended to facilitate the issue shares under the 2022 Debentures and the subsequent convertible debentures issued to Yorkville. The measures identified in clauses (1) - (3) of the preceding sentence were implemented in December 2024 in connection with the Reverse Share Split, except that the nominal value our Ordinary Shares was reduced to €0.02 per Ordinary Share and the nominal value of our High Voting Shares was reduced to €0.50 per High Voting Share, which was necessary for the Company to remain compliant with Dutch mandatory corporate law provisions in respect of minimum capital requirements. Following the satisfaction of the conditions precedent to the Debt Conversion and in connection with the creation and issuance of the Preferred Shares (as defined herein), and in accordance with the approved amendments to the Company’s articles of association the nominal value of each Ordinary Share was lowered from €0.02 per Ordinary Share to €0.01 per Ordinary Share and the nominal value of each High Voting Share was lowered from €0.50 per High Voting Share to €0.25 per High Voting Share and therewith to fully implement and perfect the items (2) and (3).

In late December 2024, the Company and Yorkville entered into a securities purchase agreement (the “Securities Purchase Agreement”), pursuant to which the Company agreed to sell and issue to Yorkville a new convertible debenture (the “New Commitment Debenture”) in the aggregate principal amount of $5 million, with a maturity date of one year following the issuance of the New Commitment Debenture. The issuance of the New Commitment Debenture was subject to certain conditions and limitations, including the condition precedent that the Company shall have received notice from Nasdaq that the Company has met all the applicable requirements for listing of the Ordinary Shares on the Nasdaq Capital Market, which occurred on September 4, 2025.

On December 30, 2024, the Company and Yorkville also entered into an exchange agreement (the “Exchange Agreement”), pursuant to which the Company agreed, subject to the satisfactions of certain conditions precedent, to issue 1,242 shares of preferred stock of the Company (the “Preferred Shares”), each with a nominal value of €300, to Yorkville solely in exchange for the surrender and cancellation of all of the debentures held by Yorkville, which at that time included the 2022 Debentures, the new convertible debentures issued to Yorkville on February 5, 2024 and August 30. 2024 (the “2024 Debentures”), and the New Commitment Debenture (if issued) (the “Debt Conversion”).

Following the Company’s receipt on September 4, 2025 of notice from Nasdaq that the Company has met all the applicable requirements for listing of the Ordinary Shares on the Nasdaq Capital Market, on September 5, 2025, the Company and Yorkville entered into a tenth Omnibus Amendment to Transaction Documents (the “Tenth Omnibus Amendment”), pursuant to which the Company and Yorkville agreed to modify the terms of the Securities Purchase Agreement, the Exchange Agreement and certain convertible debentures previously issued by the Company. Pursuant to the Tenth Omnibus Amendment, the Company and Yorkville agreed to modify the terms of the Securities Purchase Agreement to, among other things, (1) increase the aggregate principal amount of the New Convertible Debenture by an additional $2,200,000 for a total of $7,200,000, and (2) provide for an immediate advance by Yorkville to the Company of $3,409,460, which comprises the remaining $1,209,460 of the original $5,000,000 commitment and the entirety of the additional $2,200,000 commitment, in the form of a secured convertible debenture in the aggregate principal amount of $3,409,460, with a maturity date of September 5, 2026 that may be extended at the option of Yorkville (the “Seventh Debenture”, and collectively with the First Debenture, the Second Debenture, the Third Debenture, the Fourth Debenture, the Fifth Debenture and the Sixth Debenture, the “Advance Debentures”). Net proceeds to the Company from the Seventh Debenture were $3,409,460. As a result of the issuance of the Seventh Debenture, and pursuant to the Tenth Omnibus Amendment, the aggregate principal amount of the New Commitment Debenture that was to be issued to Yorkville upon the satisfaction of all of the conditions set forth in the Securities Purchase Agreement was $7,200,000, consisting of the amounts advanced to the Company under the Seventh Debenture and each of the other Advance Debentures. Under the terms of the Tenth Omnibus Amendment, the Company and Yorkville also amended the Exchange Agreement to include all of the Advance Debentures within the scope of the Exchange Agreement and therefore within the scope of the Debt Conversion, subject to the satisfaction of the conditions precedent thereto.

See “Note 16 – Subsequent Events” in Part II, Item 8 of this Annual Report for information regarding our financing arrangements with Yorkville subsequent to the fiscal year ended December 31, 2025.

Available Information

As of January 1, 2025, the Company began reporting with the SEC as a domestic issuer instead of a foreign private issuer. As a result, the Company is subject to the same reporting and disclosure requirements applicable to domestic U.S. companies, and is required to file periodic reports and financial statements with the SEC on Form 10-K and Form 10-Q, as applicable, as well as filing current reports on Form 8-K. Prior to January 1, 2025, the Company was a foreign private issuer and, in compliance with SEC regulations, the Company filed or furnished periodic and current reports with the SEC on the reporting forms available to foreign private issuers, namely Form 20-F and Form 6-K.

We make available on or through our website (https://ir.sonomotors.com/) certain reports and amendments to those reports that we file with or furnish to the SEC in accordance with the Exchange Act. These include our annual reports on Form 10-K (and previously on Form 20-F), our quarterly reports on Form 10-Q, and our current reports on Form 8-K (and previously on Form 6-K), and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act. We make this information available on or through our website free of charge as soon as reasonably practicable after we electronically file the information with, or furnish it to, the SEC. The SEC maintains a website at www.sec.gov that contains reports, proxy and information statements and other information regarding us that we filed electronically with the SEC. The information in or accessible through the SEC are not incorporated into, and are not considered part of, this Annual report unless specified. Further, the information contained on, or that can be accessed through, our website is not incorporated by reference into this Annual Report, and you should not consider any information contained on, or that can be accessed through, our website to be part of this Annual Report.

Item lA. Risk Factors.

Our business involves significant risks, some of which are described below. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Annual Report. The realization of any of these risks and uncertainties could have a material adverse effect on our reputation, business, financial condition, results of operations, growth and future prospects as well as our ability to accomplish our strategic objectives. Additional risks and uncertainties of which we are not presently aware or that we currently deem immaterial could also materially affect our business operations and financial condition.  

Risks Related to our former Self-Administration Proceedings

Despite our emergence from our former Self-Administration Proceedings, the proceedings may materially and adversely affect our operations, including by consuming significant time and attention of our management team, adversely affecting our ability to maintain important relationships with creditors, customers, suppliers, service providers, employees and counterparties and impacting our ability to pursue new customer arrangements and projects.

We will attempt to minimize the potential adverse effect of our former Self-Administration Proceedings on our relationships with creditors, customers, suppliers, service providers, employees and counterparties. Nonetheless, these relationships may be adversely impacted and our operations could be materially and adversely affected.

For instance, negative publicity associated with the Self-Administration Proceedings may adversely affect our commercial relationships and our ability to negotiate favorable terms with important stakeholders and counterparties. Public perception of our continued viability may also adversely affect our relationships with customers and their loyalty to us, as well as our ability to pursue new customer arrangements and projects. Strains in any of these relationships could materially and adversely affect us.

Our management has been required to spend a significant amount of time and effort focusing on the former proceedings instead of focusing exclusively on our business operations and will be required to continue to do so in the context of the Subsidiary’s compliance with any remaining obligations under the Plan. This diversion of attention may have a material adverse effect on the conduct of our business and, as a result, our financial condition and results of operations.

In addition, our employees faced considerable distraction and uncertainty during the pendency of the proceedings, which may lead to increased levels of employee attrition. Apart from negatively affecting our ability to retain existing high performing employees, executives and supervisory board members, the former proceedings may also prevent us from attracting new employees, executives and supervisory board members. Failure to retrain, motivate or attract key personnel or a material erosion of employee morale could impair our ability to execute our strategy and implement operational initiatives, thereby adversely affecting us.

Risks Related to the Company

We intend to use the net proceeds from our recent financings to purchase digital assets, including Bitcoin, the price of which has been, and will likely continue to be, highly volatile. Our operating results and share price may significantly fluctuate, including due to the highly volatile nature of the price of such digital assets and erratic market movements.

We intend to use the net proceeds from our recent financings to purchase or otherwise acquire BTC and for the establishment of our digital asset treasury operations. Digital assets, such as BTC, generally are highly volatile assets, including as a result of shifts in market sentiment, speculative trading, macroeconomic trends, technology-related disruptions and regulatory announcements. In addition, digital assets do not pay interest or other returns, unless utilized in staking or financial applications, and so the ability to generate a return on investment from the net proceeds of any capital raisings will principally depend on whether there is appreciation in the value of digital assets following our purchases of digital assets with the net proceeds from such capital raisings. Future fluctuations in digital asset trading prices may result in our converting digital assets into cash with a value substantially below what we paid for such digital assets.

We have adopted a digital asset treasury strategy with a focus on BTC, and we may be unable to successfully implement this new strategy.

We have adopted a digital asset treasury primarily dedicated to BTC and potential acquisitions BTC, including through staking and other decentralized finance activities. There is no assurance that we will be able to successfully implement this new strategy or operate BTC or other digital asset-related activities at the scale or profitability currently anticipated. This strategic shift requires specialized employee skillsets and operational, technical and compliance infrastructure to support BTC and related staking activities. This also requires that we implement different security protocols and treasury management practices. Further, there is ongoing scrutiny and limited formal guidance from regulatory agencies, including Nasdaq and the SEC, with respect to the treatment of public company cryptocurrency strategies. There is no assurance that we will be able to execute this Treasury Strategy by building out the needed infrastructure within the timeframe that we currently anticipate. Errors by key management could result in significant loss of funds and reduced rewards. As a result, our shift towards BTC could have a material adverse effect on our business and financial condition.

In addition, as previously disclosed, we intend to solicit the ratification by our shareholders of the engagement by the Company in the Treasury Strategy. Under Dutch law, the ratification by our shareholders of our engagement in the Treasury Strategy is required to successfully implement the Treasury Strategy.

Our Ordinary Shares may trade at a discount to our net asset value, and investors could experience losses unrelated to the performance of our underlying digital asset holdings.

The market price of our Ordinary Shares may not reflect, and at times may trade materially below, our net asset value (“NAV”) per share. A variety of factors may cause the trading price of our Ordinary Shares to deviate from our NAV, including overall market conditions, investor sentiment toward digital assets or our business model, the liquidity and volatility of the specific digital assets we hold, the availability and cost of capital to market participants, the level of short interest in our Ordinary Shares, actual or perceived governance or operational risks, and the absence of any redemption or exchange feature that would allow shareholders to realize NAV directly. As a result, the market price of our Ordinary Shares may be influenced by factors other than the value of our underlying assets alone and there can be no assurance that our Ordinary Shares will trade at or near NAV.

If our Ordinary Shares trade at a discount to NAV, investors who sell shares may receive less than the value of our underlying assets per share, and the discount could impair our ability to raise capital on favorable terms. We may from time to time consider capital markets transactions, financing arrangements or other corporate actions intended to address any discount, but we are under no obligation to take such actions and any such actions, if implemented, may be limited in scope or effectiveness.

Our shift towards a BTC-focused strategy requires substantial changes in our day-to-day operations and exposes us to significant operational risks.

Our shift towards a BTC treasury-focused strategy, including staking and other decentralized finance activities, exposes us to significant operational risks. The Bitcoin ecosystem rapidly evolves, with frequent upgrades and protocol changes that may require significant adjustments to our operational setup. The upgrades and protocol changes may require that we incur unanticipated costs and could cause temporary service disruptions to the Bitcoin network. We may also need to employ third-party service providers in our operations, which may introduce risks outside of our control, including significant cybersecurity risks. Any of these operational risks could materially and adversely affect our ability to execute the Treasury Strategy and may prevent us from realizing positive returns and could severely hurt our financial condition.

The concentration of our BTC holdings enhances the risks inherent in our Bitcoin-focused strategy.

We have and intend to purchase BTC and increase our overall holdings of BTC in the future. The intended concentration of our BTC holdings limits the risk mitigation that we could achieve if we were to purchase a more diversified portfolio of treasury assets, and the absence of diversification enhances the risks inherent in our Bitcoin-focused strategy.

If the Bitcoin network is disrupted or encounters any unanticipated difficulties, the value of BTC could be negatively impacted.

If the Bitcoin network is disrupted or encounters any unanticipated difficulties, then the processing of transactions on the Bitcoin network may be disrupted, which in turn may prevent us from depositing or withdrawing BTC from our accounts with our custodian or otherwise affecting BTC transactions. Such disruptions could include, for example: the insolvency, business failure, interruption, default, failure to perform, security breach, or other problems of participants, custodians, or others; the closing of BTC trading platforms due to fraud, failures, security breaches or otherwise; or network outages or congestion, power outages, or other problems or disruptions affecting the Bitcoin network. Any disruption of the Bitcoin network could result in the inability of the Company to transfer or sell BTC, and the price of BTC.

BTC and other digital assets are novel assets, and are subject to significant legal, commercial, regulatory and technical uncertainty, which could materially adversely affect the Company’s financial position, operations and prospects.

BTC and other digital assets, as well as applications on blockchain networks such as Bitcoin, are relatively novel and are subject to significant uncertainty, which could adversely impact their price. The application of state and federal securities laws and other laws and regulations to digital assets and blockchain-based applications is unclear in certain respects, and it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that adversely affects the price of BTC or other digital assets, or the ability of blockchain-based applications to operate.

The U.S. federal government, states, regulatory agencies, and foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of BTC or the ability of individuals or institutions such as us to own or transfer BTC and utilize blockchain-based applications on networks such as Bitcoin. For example, the U.S. executive branch, the SEC, the European Union’s Markets in Crypto Assets Regulation, among others, have been active in recent years, and in the United Kingdom, the Financial Services and Markets Act 2023 became law. Additionally, legislative and regulatory priorities may change depending on changes in leadership, as evidenced by recent and proposed initiatives such as the Genius Act of 2025, the anticipated Digital Asset Market Clarity Act, and updates to the Commission’s Regulatory Flexibility Agenda. It is not possible to predict whether, or when, any of these developments will lead to Congress granting additional authorities to the SEC, Commodity Futures Trading Commission (“CFTC”), or other regulators, or whether, or when, any other federal, state or foreign legislative bodies will take any similar actions. It is also not possible to predict the nature of any such additional authorities, how additional legislation or regulatory oversight might impact the ability of digital asset markets to function or the willingness of financial and other institutions to continue to provide services to the digital assets industry, nor how any new regulations or changes to existing regulations might impact the value of digital assets generally and BTC specifically. The consequences of increased regulation of digital assets and digital asset activities could adversely affect the market price of BTC and in turn adversely affect the market price of our Ordinary Shares.

Moreover, the risks of engaging in a digital asset treasury strategy are relatively novel and have created, and could continue to create complications due to the lack of experience that third parties have with companies engaging in such a strategy, such as increased costs of director and officer liability insurance or the potential inability to obtain such coverage on acceptable terms in the future.

The growth of the digital assets industry in general, and the use and acceptance of BTC in particular, may also impact the price of BTC and is subject to a high degree of uncertainty. The pace of worldwide growth in the adoption and use of the Bitcoin network and BTC may depend, for instance, on public familiarity with digital assets, ease of buying, accessing or gaining exposure to BTC, institutional demand for BTC as an investment asset, the participation of traditional financial institutions in the digital assets industry, consumer demand for BTC as a means of payment, and the availability and popularity of alternatives to BTC. Even if growth in BTC adoption occurs in the near or medium term, there is no assurance that BTC and the Bitcoin network usage will continue to grow over the long term.

A variety of technical factors related to the Bitcoin blockchain could also impact the price of BTC. The liquidity of BTC may also be reduced and damage to the public perception of Bitcoin may occur, if financial institutions were to deny or limit banking services to businesses that hold BTC, provide Bitcoin-related services or accept BTC as payment, which could also decrease the price of BTC.

The liquidity of BTC may also be impacted to the extent that changes in applicable laws and regulatory requirements negatively impact the ability of exchanges and trading venues to provide services for BTC and other digital assets.

Changes in regulatory interpretations could require us to register as a money services business or money transmitter, leading to increased compliance costs or operational shutdowns.

The regulatory regime for digital assets in the U.S. and elsewhere is uncertain. The Company may be unable to effectively react to proposed legislation and regulation of digital assets, which could adversely affect its business.

If regulatory changes or interpretations require us to register as a money services business with The Financial Crimes Enforcement Network (FinCEN) under the U.S. Bank Secrecy Act, or as a money transmitter under state laws, we may be subject to extensive regulatory requirements, resulting in significant compliance costs and operational burdens. In such a case, we may incur extraordinary expenses to meet these requirements or, alternatively, may determine that continued operations are not viable. If we decide to cease certain operations in response to new regulatory obligations, such actions could occur at a time that is unfavorable to investors.

Multiple states have implemented or proposed regulatory frameworks for digital asset businesses. Compliance with such state-specific regulations may increase costs or impact our business operations. Further, if we or our service providers are unable to comply with evolving federal or state regulations, we may be forced to dissolve or liquidate certain operations, which could materially impact our investors.

If any of the digital assets that we hold are classified as a security, we may be subject to extensive regulation, which could result in significant costs or force us to cease operations.

Regulatory changes or interpretations that classify digital assets that we hold as a security under the Securities Act of 1933, as amended, or the Investment Company Act, could require us to register and comply with additional regulations. Compliance with these requirements could impose extraordinary, non-recurring expenses on our business. If the costs and regulatory burdens become too great, we may be forced to modify or cease certain operations, which could be detrimental to our investors.

The SEC has previously indicated that certain digital assets may be considered securities depending on their structure and use. Future developments could change the legal status of digital assets that we may hold, requiring us to comply with securities laws. If we fail to do so, we may be forced to discontinue some or all of our business activities, negatively impacting investments in our securities.

If the SEC or other regulators determine that digital assets that we may hold qualify as securities, we may be required to change our operations, wind down our operations, or register as an investment company under the Investment Company Act. This classification would subject us to additional periodic reporting, disclosure requirements, and regulatory compliance obligations, significantly increasing our operational costs. Compliance with the requirements of the Investment Company Act applicable to registered investment companies may make it difficult for us to continue our current operations, and this would materially and adversely affect our business, financial condition and results of operations. In addition, if BTC or another digital asset we hold were determined to constitute a security for purposes of the federal securities laws, we would likely take steps to reduce the percentage of BTC or such other digital assets that constitute investment assets under the Investment Company Act. These steps may include, among others, selling BTC that we might otherwise hold for the long term and deploying our cash in non-investment assets, and we may be forced to sell our BTC or other digital assets at unattractive prices, or cease our operations.

Although we do not currently engage in investing, reinvesting, or trading securities, and we do not hold ourselves out as an investment company, we could inadvertently be deemed one under the Investment Company Act. If we are unable to rely on an exclusion, we would be required to register with the SEC, which could impose additional financial and regulatory burdens.

Further, state regulators may conclude that the digital assets we hold are securities under state laws, requiring us to comply with state-specific securities regulations. States like California have stricter definitions of “investment contracts” than the SEC, increasing the risk of additional regulatory scrutiny.

The classification of digital assets that we hold as a commodity could subject us to additional CFTC regulation, resulting in significant compliance costs or the cessation of certain operations.

Under current interpretations, BTC could be classified as a commodity under the Commodity Exchange Act and could be subject to regulation by the CFTC. If our activities require CFTC registration, we may be required to comply with extensive regulatory obligations, which could result in significant costs and operational disruptions. Additionally, current and future legislative or regulatory developments, including new CFTC interpretations, could further impact how BTC is classified and traded.

If BTC are regulated as a commodity, we may be required to register as a commodity pool operator and register the Company as a commodity pool with the CFTC through the National Futures Association. Compliance with these additional regulatory requirements could result in substantial, non-recurring expenses, adversely affecting an investment in our securities. If we determine not to comply with such regulations, we may be forced to cease certain operations, which could negatively impact our investors.

We are not subject to legal and regulatory obligations that apply to investment companies such as mutual funds and exchange-traded funds, or to obligations applicable to investment advisers.

Mutual funds, exchange-traded funds (ETFs) and their management are subject to extensive regulation as “investment companies” and “investment advisers” under U.S. federal and state law; this regulation is intended for the benefit and protection of investors. We are not subject to, and do not otherwise voluntarily comply with, these laws and regulations. This means, among other things, that the execution of our changes to our digital asset strategy, our use of leverage, our ability to engage in transactions with affiliated parties and our operating and investment activities generally are not subject to the extensive legal and regulatory requirements and prohibitions that apply to investment companies and investment advisers.

Due to the unregulated nature and lack of transparency surrounding the operations of many digital asset trading venues, digital asset trading venues experience greater risk of fraud, market manipulation and other deceptive marketing practices, as well as security failures or regulatory or operational problems than trading venues for more established asset classes, which may result in a loss of confidence in digital asset trading venues and adversely affect the value of digital assets, and the Company’s financial position, operations and prospects.

Digital asset trading venues are relatively new and, in many cases, unregulated. Furthermore, there are many digital asset trading venues that do not provide the public with significant information regarding their ownership structure, management teams, corporate practices and regulatory compliance. As a result, the marketplace may lose confidence in digital asset trading venues, including prominent exchanges that handle a significant volume of such trading and/or are subject to regulatory oversight, in the event one or more digital asset trading venues cease or pause for a prolonged period the trading of digital assets, or experience fraud, significant volumes of withdrawal, security failures or operational problems.

Negative perception, a lack of stability in the broader digital asset markets and the closure, temporary shutdown or operational disruption of digital asset trading venues, lending institutions, institutional investors, institutional miners, custodians, or other major participants in the digital asset ecosystem, due to fraud, business failure, cybersecurity events, government-mandated regulation, bankruptcy, or for any other reason, may result in a decline in confidence in digital assets and the broader digital asset ecosystem and greater volatility in the price of digital assets. The price of our listed securities may be affected by the value of our future digital asset holdings, and the failure of a major participant in the ecosystem could have a material adverse effect on the market price of our listed securities.

Our historical financial statements do not reflect the potential variability in earnings that we may experience in the future relating to our proposed holdings of digital assets. Accordingly, it may be difficult to evaluate the Company’s business and future prospects, and the Company may not be able to achieve or maintain profitability in any given period.

Our historical financial statements do not reflect the potential variability in earnings that we may experience in the future from holding or selling digital assets. The price of digital assets generally has historically been subject to dramatic price fluctuations and is highly volatile. We will need to perform an analysis each quarter to identify whether events or changes in circumstances indicate that our digital assets are impaired. As a result, volatility in our earnings may be significantly more than what we experienced in prior periods.

The lack of legal recourse and insurance for digital assets increases the risk of total loss in the event of theft or destruction.

Digital assets that we acquire will not be insured against theft, loss or destruction. If an event occurs where we lose our digital assets, whether due to cyberattacks, fraud or other malicious activities, we may not have any viable legal recourse or ability to recover the lost assets. Unlike funds held in insured banking institutions, our digital assets are not protected by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. If our digital assets are lost under circumstances that render another party liable, there is no guarantee that the responsible party will have the financial resources to compensate us. As a result, we and our shareholders could face significant financial losses.

The Company will face risks relating to the custody of its digital assets. If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to our private keys, or if our private keys are lost or destroyed, or other similar circumstances or events occur, we may lose some or all of our digital assets and our financial condition and results of operations could be materially adversely affected.

We expect our primary counterparty risk with respect to our BTC will be custodian performance obligations under the custody arrangements we enter into. A series of high-profile bankruptcies, closures, liquidations, regulatory enforcement actions and other events relating to companies operating in the digital asset industry, the closure or liquidation of certain financial institutions that provided lending and other services to the digital assets industry, SEC enforcement actions against other providers, or placement into receivership or civil fraud lawsuit against digital asset industry participants have highlighted the perceived and actual counterparty risk applicable to digital asset ownership and trading. Legal precedent created in these bankruptcies and other proceedings may increase the risk of future rulings adverse to our interests in the event one or more of our custodians becomes a debtor in a bankruptcy case or is the subject of other liquidation, insolvency or similar proceedings.

No assurance can be provided that our custodially held BTC will not become part of the custodian’s insolvency estate if one or more of our custodians enters bankruptcy, receivership or similar insolvency proceedings. Additionally, if we pursue any strategies to create income streams or otherwise generate funds using our BTC holdings, we would become subject to additional counterparty risks. We will need to carefully evaluate market conditions, including price volatility as well as service provider terms and market reputations and performance, among others, prior to implementing any such strategy, all of which could affect our ability to successfully implement and execute on any such future strategy. These risks, along with any significant non-performance by counterparties, including in particular the custodian or custodians with which we will custody substantially all of our BTC, could have a material adverse effect on our business, prospects, financial condition, and operating results.

The irreversibility of digital asset transactions exposes us to risks of theft, loss and human error, which could negatively impact our business.

Digital asset transactions are not, from an administrative perspective, reversible without the consent and active participation of the recipient of the transaction or, in theory, control or consent of a majority of the processing power on that digital asset network. Once a transaction has been verified and recorded in a block that is added to the blockchain, an incorrect transfer of digital assets or a theft of digital assets generally will not be reversible, and we may not be capable of seeking compensation for any such transfer or theft

Although we plan to regularly transfer digital assets to or from vendors, consultants and services providers, it is possible that, through computer or human error, or through theft or criminal action, such assets could be transferred in incorrect amounts or to unauthorized third parties.

To the extent we are unable to seek a corrective transaction to identify the third party which has received our digital assets through error or theft, we will be unable to revert or otherwise recover the impacted digital assets, and any such loss could adversely affect our business, results of operations and financial condition.

The emergence or growth of other digital assets, including those with significant private or public sector backing, including by governments, consortiums or financial institutions, could have a negative impact on the price of BTC and adversely affect the Company’s securities.

Following the launch of the Company’s proposed digital asset treasury strategy, as a result of our Bitcoin-focused strategy, we expect our assets to be concentrated in BTC holdings. Accordingly, the emergence or growth of digital assets other than BTC, including those with significant private or public sector backing, including by governments, consortiums or financial institutions, may have a material adverse effect on our financial condition. There are numerous alternative digital assets and many entities, including consortiums and financial institutions, are researching and investing resources into private or permissioned blockchain platforms. If the mechanisms or network effects on alternative blockchain platforms are perceived as superior to the Bitcoin network, those digital assets could gain market share relative to Bitcoin.

Risks Related to Our Business and Operations

We have a history of significant operating losses since inception and our ability to continue as a going concern is subject to significant uncertainty, and there can be no assurance that our Treasury Strategy will be successfully implemented or that additional financing will not be required.

For the year ended December 31, 2025, we recorded a profit of €4.0 million, mainly due to the recorded gain from change in the fair value of convertible debentures carried at fair value. For the same period we recorded an operating loss of €7.7 million, while our net cash used in operations amounted to €7.3 million. We have incurred net losses since our inception in March 2016 up until 2024, resulting in an accumulated deficit of €317.4 million as of December 31, 2025 compared to an accumulated deficit of €321.4 million as of December 31, 2024.

Subsequent to December 31, 2025, we implemented a series of actions intended to improve liquidity and reduce ongoing cash requirements. These actions, which are more fully described in “Item 17 – Subsequent Events” of Part II, Item 8 of this Annual Report, included: (i) raising gross proceeds of approximately $5.0 million in March 2026, consisting of a $3.0 million convertible debenture and a pre-funded warrant issued for aggregate proceeds of approximately $2.0 million; (ii) adopting our Treasury Strategy and entering into an institutional framework with Blockchain.com (BVI) II Limited in the form of the ISDA Master Agreement and the related Schedule and Credit Support Annex, to facilitate related derivative and hedging transactions in connection with our digital asset holdings; and (iii) terminating current and future funding commitments to the Subsidiary (Sono Motors GmbH) and initiating our exit from the legacy solar operations conducted through the Subsidiary, which is expected to materially reduce our ongoing cash outflows. Management believes that these actions, taken together, may provide sufficient resources to fund our streamlined operating plan under the Treasury Strategy, consisting principally of holding company overhead and public company compliance costs, for at least twelve months from the date the financial statements are issued. Our independent registered public accounting firm has included a going concern explanatory paragraph in its report on our financial statements for the year ended December 31, 2025, indicating that substantial doubt about the Company's ability to continue as a going concern exists.    

However, our ability to maintain adequate liquidity remains subject to significant uncertainties, including, among other things, the price volatility and liquidity characteristics of digital assets, the terms and potential collateral requirements of transactions entered into in connection with the Treasury Strategy, the timing and costs associated with exiting the legacy solar operations (which we are currently unable to estimate), and that our outstanding convertible debenture issued to Yorkville in the first quarter of fiscal 2026 will reach maturity in March 2027, which may require us to negotiate a refinancing or conversion of the debenture prior to or at maturity. There can be no assurance that the Treasury Strategy will generate the anticipated returns, that the exit from our legacy solar operations will be completed without material unforeseen costs, or that additional financing will not be required beyond the next twelve months. If we are unable to generate sufficient cash flows from the Treasury Strategy or to secure additional financing as required, we may need to curtail our operations, which could adversely affect our business, financial condition, results of operations and cash flows, and may ultimately lead to insolvency or liquidation.

In addition, as a result of the opening of self-administration proceedings in 2023, the Company lost control of Sono Motors GmbH on May 19, 2023 and regained control upon the Subsidiary's exit from those proceedings on February 29, 2024. In the first quarter of 2026, the Company determined to cease funding to Sono Motors GmbH and exit its legacy solar business to focus exclusively on the Treasury Strategy, as described above. As a result, our financial information going forward may in many respects not be comparable to our historical financial information.

We have identified multiple material weaknesses in our internal control over financial reporting and, as a result, management has concluded that our internal control over financial reporting and our disclosure controls and procedures were not effective as of December 31, 2025. Even though we plan on remediating these material weaknesses, if we are unable to do so, or if other control deficiencies are identified as a result of ongoing or future processes, we may not be able to report our financial results accurately, prevent fraud or file our periodic reports as a public company in a timely manner.

In connection with the audits of our consolidated financial statements for the years ended December 31, 2024, 2023 and 2022, and management’s assessment of the effectiveness of our internal controls and procedures for the year ended December 31, 2025, we identified multiple material weaknesses in our internal control over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or condensed consolidated interim financial statements will not be prevented or detected on a timely basis. Due to the multiple material weaknesses identified, which had not been remediated as of December 31, 2025, our management concluded that our internal control over financial reporting and our disclosure controls and procedures were not effective as of December 31, 2025.

In light of the Companies’ successful emergence from their respective Self-Administration Proceedings and the restructuring and recapitalization of our businesses, we are currently planning measures to remedy such material weaknesses. Beginning January 1, 2025, the planned remedial measures began with the hiring of additional accounting staff and the appointment of a new chief financial officer who possess the requisite skills to address technical accounting and reporting issues and implement processes that include taking steps to improve our controls and procedures. We continue to devote attention to remediating these deficiencies and specifically plan to incorporate automated and software-based accounting tools, engage third parties to support our internal resources related to accounting and internal controls, implement ongoing internal trainings for our accounting and finance teams and continue to invest in our finance IT systems. While we are continuing to work on remediating the weaknesses identified, and plan to remediate these weaknesses in 2026, based on our limited financial and operational resources, we cannot at this time guarantee that we will have remediated these material weaknesses this year. The remediation measures are time-consuming and costly and place significant demands on our financial and operational resources.

During the course of documenting and testing our internal control procedures in the future, we, or an outside advisor, may identify other weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act.

Further we are non-compliant with the Dutch financial reporting requirements with regard to the timely filing of our audited 2023, 2022, 2021 and 2020 Dutch statutory financial statements with the Dutch trade register and, following the corporate measures implemented in connection with the restructuring of our business and resulting personnel and other limitations, it is likely that we will not be timely with the filing of our audited 2024 Dutch statutory financial statements with the Dutch trade register. Dutch financial reporting rules require the timely filing of our audited Dutch statutory financial statements with the Dutch trade register. Non-compliance with these filing requirements exposes us to penalties and fines. Non-compliance with the requirements under Dutch law with respect to the preparation, audit and publication of our Dutch statutory financial statements could also lead to increased exposure for our management board and supervisory board members to direct liability under the standards of Dutch corporate law, which may negatively affect our reputation.

In addition, the Subsidiary is non-compliant with German financial reporting requirements with regard to the timely filing of its 2024 statutory financial statements with the German trade register and the German Federal Gazette, which has in the past led, and - until compliance is established - may in the future lead, to the imposition of penalties and fines. German financial reporting rules under the Securities Trading Act (Vermögensanlagegesetz) require the timely filing of the Subsidiary’s audited German statutory financial statements by June 30 of the year following the applicable financial period. Non-compliance with these filing requirements exposes us to penalties and fines.

Any failure on our part to discover and/or remediate existing material weaknesses, to discover and address any other control deficiencies and to achieve and maintain an effective internal control environment, could result in inaccuracies in our consolidated financial statements, could impair our ability to comply with applicable financial reporting requirements and make related regulatory filings on a timely basis and could cause investors to lose confidence in our reported financial information. This could, in turn, limit our access to capital markets, harm our results of operations and lead to a decline in the trading price of our Ordinary Shares. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential regulatory investigations and civil or criminal sanctions. We cannot assure you that all of our existing material weaknesses have been identified, that we will not identify additional material weaknesses in the future or that we will be able to achieve and maintain an effective internal control environment.

Our advertisements may not have complied in the past with all relevant legal requirements and may be subject to misperception.

We cannot guarantee that all of our public statements that qualify as advertisements, or whole advertising campaigns, comply with legal requirements under competition law or other laws, rules or regulations. Any non-compliance could lead to administrative fines and may result in us being required to discontinue a campaign. We may also be forced to publicly correct incorrect statements. In addition, our public communications also may have contained incorrect information or statements or may be subject to misperception. We often advertise our products with rather general characteristics and specifications that are subject to interpretation, such as “green” or “environmentally friendly” and any statement relating thereto may spark discussions, challenges or legal claims should any of our customers or other third party have an understanding of these characteristics and specifications that differs from ours. Any of the foregoing could adversely affect our reputation and brand and our business.

Interruptions or failures of information technology and communications systems could disrupt our business and affect our ability to effectively provide our services.

We utilize information technology systems and networks as well as cloud computing services to process, transmit and store electronic information in connection with our business activities. We manage and maintain our applications and data utilizing a combination of on-site systems as well as externally managed data centers and cloud-based data centers. We utilize third-party security and infrastructure service providers to manage our information technology systems and data centers. These applications and data encompass a wide variety of business-critical information, including research and development information, commercial information and business and financial information, as well as personal data of customers, community members or employees. In addition, we also rely on independent third-party service providers, such as Google, which play an important role for our product offering, marketing channels and overall presence. Our data of any kind stored on the cloud services and on individual devices could be lost due to improper handling, insufficient commissioning of third parties to create backup copies damage or accidental or intentional deletion by our employees. Our data could also fall into the hands of third parties, whether through espionage, hacking or incorrect operation of the systems. Any unauthorized access to our data or any asset could result in its leakage, loss, manipulation or fraud or materially impair our business operations.

Despite the implementation of security measures by us or our service partners, our or our service partners’ systems, as well as those of any relevant third-party service provider will be vulnerable to damage or interruption from, among others, fire, terrorist attacks, natural disasters, power loss, telecommunications failures, computer viruses, computer denial of service attacks or other attempts to harm our systems. The relevant data centers could also be subject to break-ins, sabotage and intentional acts of vandalism causing potential disruptions. Some of our or our service providers’ systems will not be fully redundant, and our disaster recovery planning cannot account for all eventualities.

Any problems with, or insufficiencies of, our or our service providers’ data centers or services could result in lengthy interruptions of our or our service providers’ information technology systems. Cyber threats are persistent and constantly evolving. Such threats have increased in frequency, scope and potential impact in recent years. Information technology evolves rapidly and we or our service providers may not be able to address or anticipate all types of security threats and may not be able to implement preventive measures effective against all such security threats. The techniques used by cyber criminals change frequently, may not be recognized until launched and can originate from a wide variety of sources, including outside groups such as external service providers, organized crime affiliates, terrorist organizations or hostile foreign governments or agencies. There can be no assurance that we or our service providers, contractors or consultants will be successful in preventing cyberattacks or successfully mitigating their effects. Similarly, there can be no assurance that any third-party service provider will be successful in protecting our confidential and other data that is stored on their systems. In addition, we may suffer reputational harm or face litigation or adverse regulatory action as a result of cyberattacks or other data security breaches and may incur significant additional expense to implement further data protection measures. Any disruption of the networks and services of independent third-party service providers could also negatively affect our operations, accessibility or offering

We are exposed to various liability risks resulting from past or existing employment relationships and labor laws.

In light of our decision to terminate the Sion program in February 2023 and our financial situation, we terminated the vast majority of our employees. Thereafter, in connection with the corporate structure and business model envisioned in the Yorkville Investment Agreements, including the streamlined initial business focus on the Solar Bus Kit, we terminated the contracts of 40 employees, including the contracts of the four managing directors of the Subsidiary, in September 2023. In addition, in line with our streamlined operational approach and strategic focus on key partnerships, the Subsidiary has over the last year implemented a reduction in workforce. There may be further reductions in its workforce as a result of the termination by the Company of all current and future funding commitments to the Subsidiary and the decision to exit the legacy solar operations conducted through the Subsidiary. In the event of any employee terminations, we face the risk of legal proceedings in which the former employees may challenge their termination, claim damages or other payments and benefits in relation to their employment relationship or seek ownership in intellectual property rights and other assets. Should employees be successful in challenging terminations, we may be exposed to substantial financial and other liabilities. In addition, despite their termination, former employees may still claim to be, fully or partially, entitled to certain benefits granted to them while they were still employed with us, such as, for example, certain incentives, bonuses or pension entitlements. We may also be liable for substantial social security contributions with respect to terminated employees for a prolonged time.

Workforce management poses various risks and challenges, particularly in the EU and Germany, where the vast majority of our workforce is located. The labor laws in Germany are complex and rather employee-friendly. For example, the German Working Time Act (Arbeitszeitgesetz) sets out a strict framework for, among others, the length of working shifts and resting breaks, the definition of working days and holidays, work on holidays, compensation and the obligation of employers to record working times of employees. There can be no assurance that we have complied or will comply in all material aspects with applicable labor laws, which may lead to the imposition of material fines or even criminal liability and may significantly negatively affect our reputation.

Regulations and stakeholder expectations relating to environmental, social and governance matters may impose additional costs and expose us to new risks.

We continue to closely monitor developments relating to environmental, social and governance (“ESG”) regulations. At the federal level in the United States, the SEC has proposed new rules requiring public companies to disclose extensive climate-related information in their registration statements and periodic reports. Such proposed rules have been stayed pending the completion of the judicial review of several petitions consolidated in the U.S. Court of Appeals for the Eight Circuit and are currently being reconsidered by the SEC under the new U.S. administration. The countries in which we operate are following different approaches to the regulation of climate change and other sustainability matters, which increases the complexity of, and potential costs related to complying with, such regulations.

Simultaneously, there are efforts by some stakeholders to reduce companies’ efforts on certain ESG, including human capital management-related matters, and anti-ESG or anti-diversity, equity and inclusion (“DEI”) sentiment is gaining momentum across the United States, with several states having enacted or proposed anti-ESG or anti-DEI policies or legislation and several state and federal governmental authorities filing suit alleging that ESG or DEI measures or initiatives violate law. Additionally, in January 2025, President Trump signed a number of Executive Orders focused on DEI, which indicate continued scrutiny of DEI initiatives and potential related investigations of certain private entities with respect to DEI initiatives, including publicly traded companies. Further, some advocacy groups and federal and state officials have asserted that the U.S. Supreme Court’s decision striking down race-based affirmative action in higher education in June 2023 should be analogized to private employment matters and private contract matters and several media campaigns and cases alleging discrimination based on such arguments have been initiated since the decision. If we were sued under any of these claims, our financial condition, reputation or business could be adversely impacted. Increasingly, different stakeholder groups have divergent views on ESG matters, which increases the risk that any action or lack thereof with respect to ESG matters will be perceived negatively by at least some stakeholders and adversely impact our reputation and business. If we do not successfully manage expectations across varied stakeholder interests, it could erode stakeholder trust, impact our reputation and constrain our business opportunities.

As ESG best practices and regulations continue to evolve, we expect to incur increasing costs relating to ESG monitoring, reporting and compliance, and these efforts will require substantial time and attention of management. This could have a material adverse effect on our business, results of operations, value chain and financial condition.

Regulatory, Legal and Tax Risks

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

We are subject to substantial regulation under international, national, regional and local laws. We expect to incur significant costs in complying with these regulations. In addition, additional regulatory costs or hurdles may materialize in the future as we expand our operations, as we have not yet assessed all relevant legal aspects of our operations and current business model with respect to the relevant legal framework of all jurisdictions, we may conduct business in. Regulations related to the mobility and e-mobility industry and alternative energy are evolving and we face risks associated with changes to these regulations. We are unable to predict future legislative or regulatory changes, initiatives or interpretations and any such changes, initiatives or interpretations may increase costs and competitive pressure on us. To the extent laws change, our products may not comply with applicable international, national, regional or local laws, which would have an adverse effect on our business. Compliance with changing regulations could be burdensome, time consuming and expensive. To the extent compliance with new regulations is cost prohibitive, our business, prospects, financial condition and operating results would be adversely affected.

We are subject to various environmental laws and regulations that could impose substantial costs upon us.

Our operations have been subject to international, national, regional and/or local environmental laws and regulations, including, in the jurisdictions in which we intend to sell our products, laws relating to the use, handling, storage, disposal and human exposure to hazardous materials (including the German Federal Soil Protection Act (Bundes-Bodenschutzgesetz), and Regulation (EC) no. 1907/2006 (REACH)). Furthermore, we will be affected by the Extended Producer Responsibility, an EU policy approach under which producers are given a significant responsibility – financial and/or physical – for the treatment or disposal of post-consumer products. We may be or become subject to various environmental, social and governance-related regulations in the future, such as the EU Corporate Sustainability Reporting Directive, EU Taxonomy for sustainable activities, the EU Corporate Sustainability Due Diligence Directive or the Act on Corporate Due Diligence Obligations in Supply Chains (Lieferkettensorgfaltspflichtengesetz) including as a result of recent legislative or regulatory initiatives. Environmental and health and safety laws and regulations can be complex.

These laws can give rise to liability for administrative oversight costs, cleanup costs, property damage, bodily injury, fines and penalties. Capital and operating expenses needed to comply with environmental laws and regulations can be significant, and violations may result in substantial fines and penalties, third-party damages, suspension of production or a cessation of our operations.

We may be involved in legal proceedings based on the alleged violation of intellectual property rights either by us or third parties, such as patent or trademark infringement claims, which may be time-consuming and cause us to incur substantial costs.

Technological innovation will be a crucial aspect of our potential success. We have been granted several patents for our technologies. As the number of competitors in our market increases, and as the number of patents issued in the area of mobility grows, the possibility of patent infringement claims against us or by us increases. While we are not aware that our technologies infringe the proprietary rights of any third party or that technologies of a third party infringe our proprietary rights, we do not regularly conduct freedom to operate searches. Policing violations of our intellectual property rights or unauthorized use of our proprietary technology can be difficult and result in substantial costs. Litigation may be necessary to enforce our intellectual property rights or determine the validity and scope of our proprietary rights and of others. We cannot ensure that the outcome of such potential litigation will be in our favor, and such litigation may be costly and may divert management attention and other resources away from our business. We may not be able to manufacture or commercialize our technology as planned and our freedom to operate may be impaired, absent a license, which may not be available on reasonable terms or at all, should we fail to successfully identify or challenge any patents or patents applications that cover our technology or innovations. This risk is more pronounced against the background that it is difficult for industry participants, including us, to identify all third-party patent rights that may be relevant to our product candidates and technologies because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. We may in-license patents and other intellectual property from third parties, including suppliers and service providers, and we may face claims that our use of this in-licensed technology infringes the intellectual property rights of others. In such cases, we will seek indemnification from our licensors. However, our rights to indemnification may be unavailable or insufficient to cover our costs and losses.

We may be required to participate in interference, derivation or opposition proceedings that concern disputes regarding priority of inventions disclosed in our patents. Determining patent infringement by a product, as well as priority of inventions and other patent-related disputes, involves complex legal and factual issues and the outcome is often uncertain. We have not conducted any significant search of patents issued to third parties, and third-party patents containing claims covering our technology or methods that predate our patents may exist. Because of the number of patents issued and patent applications filed in our technical areas or fields (including some pertaining specifically to electric vehicles), we may identify third party technologies that infringe our patents, or our competitors or other third-parties may assert that our technology and the methods we employ in the use of products incorporating our technology are covered by patents held by them. In addition, because patent applications can take many years to issue and because publication schedules for pending applications vary by jurisdiction, we may not be aware of certain patent applications that are currently pending, which applications may result in issued patents that our technology would infringe. Also, because the claims of published patent applications can change between publication and patent grant, there may be published patent applications that may ultimately issue with claims that we infringe.

The scope of patent claims is subject to construction based on interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect. Established vehicle manufacturers, technology companies or other market players may invest significant resources and capital to protect their intellectual property and scan the market for potential violations. There is a heightened risk that inquiries or legal proceedings based on the alleged violation of intellectual property rights are initiated by established vehicle manufacturers or technology companies that develop and test technologies similar to ours and that have much more resources and funds than us. Other companies owning patents or other intellectual property rights relating to technologies relevant for us, such as solar modules or electronic power management systems may also allege infringement of such rights. In addition, we may also be exposed to claims from individuals who were or are engaged in the design and development of our technologies or previously developed vehicles. We initiated mass layoffs of former employees in connection with the change in our business model, which increases the risk for retaliatory actions. Former employees who left us or were terminated may seek to assert ownership in or otherwise challenge intellectual property rights that we claim or are crucial for our plans. The publicity interest we receive as a public company draws significant attention to us and likely generally increases the risks of such claims and legal proceedings, no matter whether such claims lack the required merits or not or are of merely fraudulent nature.

In addition, we may be required to indemnify our customers and distributors against claims relating to the infringement of intellectual property rights of third parties related to our products. Third parties may assert infringement claims against our customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf of our customers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of our customers or distributors, or may be required to obtain licenses for the products or services they use. If we cannot obtain all necessary licenses on commercially reasonable terms, our distributors may be forced to stop distributing our products or services, and our customers may be forced to stop using our products or services.

The outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance. Because of the substantial amount of discovery required in certain jurisdictions in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. If we are required to obtain a license from any third party in order to use the infringing technology and continue developing, manufacturing or marketing our products, we may not be able to obtain such required license on commercially reasonable terms or at all, including due to competitors being unwilling to provide us a license under any terms. A successful claim of infringement of intellectual property against us could therefore materially adversely affect our business, prospects, operating results and financial condition. Any litigation or claims, whether valid or invalid, could result in substantial costs and diversion of resources and we have not yet created any reserves for litigation related to intellectual property.

If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our markets of interest, which may adversely affect our business.

Our trademark registrations and applications are valuable assets and may be challenged, infringed, circumvented or declared generic or determined to infringe a third party’s trademarks. There is a risk that we may not be able to protect our rights to these or other trademark registrations or applications. Equally, there can be no assurance that we will be successful in registering additional or replacement trademarks if we were to engage in a rebranding. At times, competitors may adopt trademarks or trade names similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our trademark registrations or applications. We have not conducted any availability searches for trademarks to assess whether our trademark registrations would not infringe a third party’s trademarks, or whether our trademark applications would be successfully registered. Successful third-party challenges to the use of any of our trademarks may require us to rebrand our business or certain products or services associated therewith.

We may fail to adequately maintain the quality of our products and services associated with our trademarks, and any loss to the distinctiveness of our trademarks may cause us to lose certain trademark protection, which could result in the loss of goodwill and brand recognition in relation to our name and products. Our efforts in enforcing or protecting our trademarks may be ineffective and could result in substantial costs and diversion of resources and adversely affect our business.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers or claims asserting ownership of what we regard as our own intellectual property.

Some of our employees were previously employed at other companies that may have proprietary rights related to our business. Some of these employees may have executed proprietary rights, non-disclosure and noncompetition agreements in connection with such previous employment. Although we try to ensure that such individuals do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of their former employers. We are not aware of any such disclosures or threatened or pending claims related to these matters, but in the future, litigation may be necessary to defend against such claims. If we fail to defend any such claims, we may lose valuable intellectual property rights or personnel and may be required to pay monetary damages and be enjoined from conducting our business as contemplated. Even if we are successful in defending against such claims, litigation can be expensive and time-consuming.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage.

For example:

Should any of these events occur, they could have a material adverse effect on our business, financial condition, results of operations and reputation.

We may be subject to various privacy laws, the violation of which could result in substantial fines and other negative consequences.

We collect, store and process data in the course of our business operations, which may subject us to various data protection and privacy laws. The regulatory framework for data protection, privacy and security issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future.

The data and information we collect and manage in conducting our business may subject us to legislative and regulatory burdens and requirements in the EEA and the United States of America that could require notification of data breaches, restrict our use of such information and hinder our ability to acquire new customers or market to existing customers. We have not yet implemented a comprehensive set of internal- or external-facing written data protection and privacy policies, procedures and rules. Non-compliance or a major breach of our network security and systems could have serious negative consequences for our business and future prospects, including possible fines, penalties and damages, reduced customer demand for our products and harm to our reputation and brand. For instance, Regulation (EU) 2016/679 of the European Parliament and of the Council of April 27, 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (the General Data Protection Regulation, “GDPR”) imposes strict limitations on the processing of personal data. The GDPR and other data privacy laws regulate when and how personal data may be collected, for which purposes it may be processed, for how long such data may be stored and to whom and how it may be transferred. The GDPR contains strict requirements for obtaining the consent of data subjects (i.e., the persons to whom personal data relates) to the use and processing of their personal data and also requires the implementation of appropriate technical and organizational measures, depending on the nature of the processing activities, and imposes certain documentation obligations relating to data processing activities. The GDPR also imposes various obligations in the context of processing of data, including, among others, far-reaching transparency, data minimization, storage limitations, privacy by design and privacy by default obligations, data security, integrity and confidentiality obligations. In addition, it may require data protection impact assessments where the data processing is likely to result in a high risk to the rights and freedoms of individuals. In case of a violation of the provisions of the GDPR, we could be subject to fines of up to €20,000,000 or up to 4% of our total worldwide annual turnover of the preceding financial year, whichever is higher, and other administrative penalties. We may also be liable should any individual who has suffered financial or non-financial damage arising from our infringement of the GDPR exercise their right to receive compensation against us. Furthermore, adverse publicity relating to our failure to comply with the GDPR could cause a loss of goodwill, which could have an adverse effect on our reputation, brand, business and financial condition. In addition, local authorities may construe new regulations in a way that is even more restrictive and there is no guarantee that we will be able to comply with such restrictive approaches.

There is a risk that personal data that we process could become public if there were a security breach in respect of such data and, if such security breach were to occur, we could face liability under data protection laws, including the GDPR, and lose the goodwill of our customers, which may have a material adverse effect on our reputation, brand, business and financial condition. Any risk of liability under data protection laws, including the GDPR, is more pronounced against the background of our mass terminations of employees that we implemented in connection with the change in our business model and which could subject us to retaliatory actions by former employees, including willful data leakages or the disclosure of confidential information.

We are exposed to the risk of litigation or other legal proceedings that could cause us to spend substantial resources and disrupt our business.

In light of our decision to terminate the Sion passenger car program in February 2023, as of the end of March 2023, we terminated the vast majority of our employees. Thereafter, in connection with the new corporate structure and business model envisioned in the then-current negotiations surrounding the Yorkville Investment Agreements, we terminated the contracts of 40 employees, including the contracts of the four managing directors of the Subsidiary, in September 2023. In addition, in line with our streamlined operational approach and strategic focus on key partnerships, the Subsidiary has over the last year implemented a reduction in workforce. There may be further reductions in its workforce as a result of the termination by the Company of all current and future funding commitments to the Subsidiary and the decision to exit the legacy solar operations conducted through the Subsidiary. In the event of any employee terminations, we face the risk of legal proceedings in which the former employees may challenge their termination, claim damages or other payments and benefits in relation to their employment relationship or seek ownership in intellectual property rights and other assets. Should employees be successful in challenging terminations, we may be exposed to substantial financial and other liabilities. We also terminated and settled relationships with several former business partners that became obsolete. Former business partners may assert substantial payment claims or sue us for damages.

Furthermore, we may also face litigation and legal proceedings based on advertisements or other public statements should such statements turn out to be unrealistic, unfeasible or false or should the overall advertised performance or specifications of our products deviate from such advertisements or public statements.

We may or will be, as the case may be, subject to anti-corruption, anti-bribery, anti-money laundering, financial and economic sanctions and similar laws and our compliance systems may not be sufficient to adequately prevent or detect legal, financial and operational risks.

Our business may or will be subject to various laws and regulations relating to, among other things, prevention of illegal employment, bribery and corruption, and money laundering, as well as compliance with antitrust, data protection (particularly the GDPR), consumer protection, minimum wage regulations, various criminal as well as export control regulations and trade and economic sanctions and embargoes on certain countries, persons, groups and/or entities, projects and/or activities. We are reliant on the compliance of our employees and the members of our management board, our contractors, consultants, agents, vendors and (other) collaboration partners with applicable laws and compliance policies implemented by us.

However it cannot be excluded that our employees, the members of the management board, our contractors, consultants, agents, vendors and (other) collaboration partners have committed or will commit criminal, unlawful or unethical acts (including corruption) or that our compliance and risk management and its monitoring capabilities may prove insufficient to prevent or detect any breaches of the law. Any such acts or breaches of law could result in whistle-blower complaints, adverse media coverage, (criminal) investigations, significant civil, administrative and criminal penalties and damage claims, disgorgement or other sanctions, (collateral) consequences or remedial measures and legal expenses, and cause considerable damage to our reputation, thereby negatively affecting our business, results of operations, financial condition and future business opportunities.

We may become subject to additional Dutch and German taxes, in particular, due to the statutory seat of the Company in the Netherlands.

There is a risk that the German tax authorities classify the Company as Dutch tax resident. If the German tax authorities conclude that the Company is not, has ceased to be or ceases to be (also as a consequence of the change of facts or the law) a German tax resident, it could, inter alia, become subject to German exit taxation. This could have serious German tax consequences, including German exit taxes or the increase of German withholding taxes on dividends received by the Company. Such German exit taxes could lead to the taxation of the built-in gains in the assets (e.g., intellectual property or goodwill) of the Company.

If we do pay dividends, we may need to withhold tax on such dividends payable to holders of our Ordinary Shares in both Germany and the Netherlands.

We currently do not intend to pay any dividends to holders of our Ordinary Shares. However, if we do pay dividends, we may need to withhold tax on such dividends in both Germany and the Netherlands.

As an entity incorporated under Dutch law, any dividends distributed by us are subject to Dutch dividend withholding tax based on Dutch domestic law. However, on the basis of the 2012 Convention between the Federal Republic of Germany and the Kingdom of the Netherlands for the avoidance of double taxation with respect to taxes on income, or the “double tax treaty between Germany and the Netherlands,” the Netherlands will be restricted in imposing these taxes if we continue to be a tax resident of Germany and our place of effective management is located in Germany. This withholding tax restriction does, however, not apply, and Dutch dividend withholding tax is still required to be withheld from dividends, if and when paid to Dutch resident holders of our Ordinary Shares and non-Dutch resident holders of our Ordinary Shares that have a permanent establishment in the Netherlands to which their shareholding is attributable. As a result, upon a payment (or deemed payment) of dividends, we will be required to identify our shareholders in order to assess whether there are Dutch residents (or non-Dutch residents with a permanent establishment in the Netherlands to which the Ordinary Shares are attributable) in respect of which Dutch dividend tax has to be withheld. Such identification may not always be possible in practice. If the identity of our shareholders cannot be determined, withholding of both German and Dutch dividend tax may occur upon a payment of dividends.

Furthermore, the withholding tax restriction referred to above is based on the current choices and reservation made by Germany under the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (“MLI”). If Germany changes its MLI choices and reservation, we may not be entitled to any benefits of the double tax treaty between Germany and the Netherlands, including the withholding tax restriction, as long as Germany and the Netherlands do not reach an agreement on our tax residency for purposes of the double tax treaty between Germany and the Netherlands, and, as a result, any dividends distributed by us during the period no such agreement has been reached between Germany and the Netherlands may be subject to withholding tax both in Germany and the Netherlands.

We may become taxable in a jurisdiction other than Germany and this may increase the aggregate tax burden on us.

Since our incorporation we have had, on a continuous basis, our place of “effective management” in Germany (albeit that such management connection with Germany has been diluted). The German tax authorities may still deem the remaining management connection or other local presence sufficiently strong to assert taxing rights under German domestic law. As an entity incorporated under Dutch law, however, we also qualify as a tax resident of the Netherlands on the basis of Dutch domestic law. Yet, based on our current management structure and the current tax laws of the United States, Germany and the Netherlands, as well as applicable income tax treaties, and current interpretations thereof, if the German tax authorities would seek to assert taxing rights due to effective management from Germany, we should qualify solely as a tax resident of Germany for the purposes of the double tax treaty between Germany and the Netherlands due to the “effective management” tie-breaker included in Article 4(3) of the double tax treaty between Germany and the Netherlands and the current MLI choices and reservation, seeing that management ties with the Netherlands are entirely absent. Our sole tax residency in Germany for purposes of the above-mentioned tax treaty is subject to the application of the provisions on tax residency as stipulated in such treaty as amended from time to time. The MLI, Germany and the Netherlands entered into, among other countries, should not, as of this date, affect such tax treaty’s rules regarding tax residency.

The test of “effective management” is largely a question of fact and degree based on all the circumstances, rather than a question of law. Nevertheless, the relevant case law and OECD guidance suggest that our Company is unlikely to be regarded as a Dutch tax resident in a tax treaty context if, as our Company intends, (i) no management board meetings will be held in the Netherlands and management board members attending through video conferencing will not be present in the Netherlands for those meetings; (ii) at those meetings there are full discussions of, and decisions are made regarding, the key strategic issues affecting our Company and its subsidiaries; (iii) those meetings are properly minuted; (iv) none of our management board members, together with supporting staff, are based in the Netherlands; and (v) our Company does not have permanent staffed office premises in the Netherlands. We may, however, become subject to income tax liability in other countries with regard to the income generated in the respective other country, for example, due to the existence of a permanent establishment or a permanent representative in such other country.

The applicable tax laws, tax treaties or interpretations thereof may change, including the MLI choices and reservation. Furthermore, whether we have our place of effective management in Germany and are as such solely tax resident in Germany is largely a question of fact and degree based on all the circumstances, rather than a question of law, which facts and degree may also change. Changes to applicable tax laws or interpretations thereof, changes to applicable facts and circumstances (for example, a change of directors or the place where board meetings take place), or changes to applicable tax treaties, including a change to the application of the MLI, may result in a taxable presence in (an)other jurisdiction(s). See “Item 1A. Risk Factors—Regulatory, Legal and Tax Risks—If we do pay dividends, we may need to withhold tax on such dividends payable to holders of our Ordinary Shares in both Germany and the Netherlands.” As a consequence, our overall effective income tax rate and income tax expense could materially increase, which could have a material adverse effect on our business, results of operations, financial condition and prospects, which could cause our share price and trading volume to decline.

We may be or become a passive foreign investment company (“PFIC”), which could result in adverse United States federal income tax consequences to United States investors.

Based on the composition of our income and valuation of our assets we believe that we were not a PFIC in our taxable year ended December 31, 2025. The determination of whether or not we are a PFIC is made on an annual basis and will depend on the composition of our income and assets from time to time. Specifically, we will be classified as a PFIC for United States federal income tax purposes if either: (1) 75% or more of our gross income in a taxable year is passive income, or (2) the average percentage of our assets by value in a taxable year which produce or are held for the production of passive income (which includes cash) is at least 50%.

Our PFIC status is a factual determination that is made annually and thus may be subject to change. It is therefore possible that we could become a PFIC in our taxable year ending December 31, 2026, or in a future taxable year.

If we are or were to become a PFIC, such characterization could result in adverse United States federal income tax consequences and burdensome reporting requirements to a holder of Ordinary Shares if such holder is a United States investor.

Risks Related to our Securities

An investment in our securities carries a high degree of risk and should be considered as a speculative investment.

An investment in our securities carries a high degree of risk and should be considered as a speculative investment. We have a limited history of earnings, a limited operating history, have not paid dividends, and are unlikely to pay dividends in the immediate or near future. The likelihood of our success must be considered in light of the problems, expenses, difficulties, complications and delays frequently encountered in connection with the establishment of any business. An investment in our securities may result in the loss of an investor’s entire investment. Only potential investors who are experienced in high risk investments and who can afford to lose their entire investment should consider an investment our securities.

The market price of our Ordinary Shares may be highly volatile, and you could lose all or part of your investment.

The trading price of our Ordinary Shares is likely to be volatile.

Our stock price could be subject to wide fluctuations in response to a variety of other factors, which include:

In addition, the stock market in general has recently experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Such rapid and substantial price volatility, including any stock run-up, may be unrelated to our actual or expected operating performance and financial condition or prospects, making it difficult for prospective investors to assess the rapidly changing value of our Ordinary Shares. This volatility may prevent you from being able to sell your Ordinary Shares at or above the price you paid for them. If the market price of our Ordinary Shares after this offering does not exceed the offering price, you may not realize any return on your investment in us and may lose some or all of your investment.

We may, in the future, issue additional Ordinary Shares or other securities, which would reduce investors’ percent of ownership and dilute our share value.

Future sales or issuances of equity securities could decrease the value of the Ordinary Shares, dilute shareholders’ voting power and reduce future potential earnings per Ordinary Share. We may sell additional equity securities in subsequent offerings (including through the sale of securities convertible into Ordinary Shares) and may issue additional equity securities to finance our operations, acquisitions or other business projects. We cannot predict the size of future sales and issuances of equity securities or the effect, if any, that future sales and issuances of equity securities will have on the market price of the Ordinary Shares. Sales or issuances of a substantial number of equity securities, or the perception that such sales could occur, may adversely affect prevailing market prices for the Ordinary Shares. With any additional sale or issuance of equity securities, investors will suffer dilution of their voting power and may experience dilution in our earnings per Ordinary Share.

Subject to the terms of our articles of incorporation and applicable securities laws, we are not restricted from issuing additional Ordinary Shares or securities similar to the Ordinary Shares, including any securities that are convertible into or exchangeable for, or that represent the right to receive, Ordinary Shares. The market price of the Ordinary Shares could decline as a result of sales of Ordinary Shares, sales of other securities made after this offering, or as a result of the perception that such sales could occur. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future offerings. Thus, holders of the Ordinary Shares bear the risk of our future offerings reducing the market price of the Ordinary Shares and diluting their holdings in the Ordinary Shares.

Future equity issuances and digital-asset-linked financings may dilute existing shareholders and affect the market price of our Ordinary Shares.

The Company has entered into, and may in the future enter into, additional financing arrangements that could result in the issuance of a substantial number of Ordinary Shares. During fiscal 2025, the Company completed the transactions contemplated by the Yorkville Restructuring Investment and the Yorkville Commitment, in connection with which the Company issued Preferred Shares to Yorkville that are convertible into Ordinary Shares, provided, that under the Exchange Agreement, Yorkville may not convert Preferred Shares if, after giving effect to such conversion, Yorkville and any of its affiliates would beneficially own more than 4.99% of the number or voting power of the Ordinary Shares outstanding immediately after giving effect to such conversion, which limitations may be waived by Yorkville upon not less than 65 days’ prior notice to the Company. In addition, subsequent to year-end, the Company issued the Pre-Funded Warrant to Yorkville. The Pre-Funded Warrant is exercisable for up to 283,367 Ordinary Shares at an exercise price of €0.01 per share (subject to certain adjustments), is exercisable immediately upon issuance, and may be exercised, in whole or in part, at any time until exercised in full. Yorkville (together with its Attribution Parties (as defined in the Pre-Funded Warrant)) may not exercise any Pre-Funded Warrant to the extent that Yorkville would own more than 4.99% of the outstanding Ordinary Shares immediately after giving effect to the issuance of Ordinary Shares issuable upon exercise of such Pre-Funded Warrant, which percentage may be changed at Yorkville’s election to a lower or higher percentage not in excess of 9.99% upon 61 days’ notice to the Company, subject to the terms of the Pre-Funded Warrant. If such limitations are waived and all of such securities are converted or exercised, the number of outstanding Ordinary Shares could increase materially, resulting in dilution of existing shareholders’ voting and economic interests.

While these arrangements strengthen liquidity and support the Company’s growth initiatives, they also expose shareholders to potential future dilution and share-price volatility. The market price of the Company’s Ordinary Shares may fluctuate based on expectations regarding the timing, scale, or pricing of any future equity issuances under these or similar facilities.

Digital-asset treasury and market-value volatility could adversely affect our financial position and liquidity.

As part of its long-term capital strategy, the Company established a digital asset treasury (DAT) Strategy that includes holdings of BTC acquired in connection with the Treasury Strategy. While these assets are intended to generate on-chain yield and support future digital-finance initiatives, they expose the Company to risks not typically associated with traditional financial instruments.

The market for digital assets such as BTC is highly volatile and subject to rapid and material fluctuations in value due to regulatory changes, technology vulnerabilities, network-level disruptions, and shifts in market sentiment. A significant decline in BTC token prices could reduce the carrying value of the Company’s digital-asset holdings and collateral base, potentially resulting in impairment charges or the need to post additional collateral under certain custodial or trading arrangements.

In connection with the Treasury Strategy, the Company transfers Bitcoin to Blockchain.com (BVI) II Limited as collateral pursuant to the Credit Support Annex to the ISDA Master Agreement, in amounts determined by reference to the mark-to-market exposure under the outstanding derivative and hedging transactions. While such collateral is posted, the Company's ability to recover the transferred Bitcoin is contractually limited to Blockchain.com's performance of its return obligations under the Credit Support Annex. As a result, the Company bears counterparty credit exposure to Blockchain.com for the value of Bitcoin transferred as collateral. Any default, insolvency or operational failure by Blockchain.com could adversely affect the Company's ability to recover such assets, which could materially impair the Company's liquidity position and its ability to fund its ongoing operating expenses and obligations.    

Although management has implemented procedures to monitor counterparty, custody, and market-price risk, there can be no assurance that such measures will prevent losses or liquidity constraints arising from future market volatility or regulatory developments affecting digital-asset markets.

Sales of substantial amounts of our Ordinary Shares in the public market, or the perception that these sales may occur, could cause the market price of our Ordinary Shares to decline.

Sales of substantial amounts of our Ordinary Shares in the public market, or the perception that these sales may occur, could cause the market price of our Ordinary Shares to decline. This could also impair our ability to raise additional capital through the sale of our equity securities. At the January 2024 EGM, shareholders approved a reverse share split of the Ordinary Shares and the High Voting Shares. On December 23, 2024, the Company amended its articles of association to implement the Reverse Share Split at a ratio of 1-for-75 (the “Reverse Split Ratio”), resulting in every 75 Ordinary Shares issued and outstanding immediately prior to the Reverse Share Split being converted into one Ordinary Shares and every 75 High Voting Shares issued and outstanding immediately prior to the Reverse Share Split being converted into one High Voting Share. In connection therewith, our authorized share capital was reduced from 320,000,000 Ordinary Shares, with a nominal value of €0.06 each, to 4,300,000 Ordinary Shares, with a nominal value of €0.02 each, and from 4,000,000 High Voting Shares, with a nominal value of €1.50 each, to 53,400 High Voting Shares, with a nominal value of €0.50 each. In accordance with resolutions adopted and approved amendments to the Company’s articles of association at the January 2024 EGM our authorized capital was further changed to 120,000,000 Ordinary Shares, with a nominal value of €0.01 each, 40,000 High Voting Shares, with a nominal value of €0.25 each, and 1,401 Preferred Shares, with a nominal value of €300 each. Following clearance from FINRA, the Reverse Share Split took market effect on January 6, 2025. At the Company’s extraordinary meeting of shareholders on November 7, 2024 (the “November 2024 EGM”), the shareholders approved a proposal to increase (in one or a series of amendments) our authorized share capital in order to cover the increase of our authorized share capital under an authority of the management board to issue Ordinary Shares or grant rights to subscribe for Ordinary Shares. Further, pursuant to the approved and completed Debt Conversion, Yorkville received 1,401 Preferred Shares that are convertible into Ordinary Shares. The conversion of such Preferred Shares as well as the issuance of any additional Ordinary Shares will cause substantial dilution to our then existing shareholders. We cannot predict the size of future issuances of our Ordinary Shares, or the effect, if any, that future issuances and sales of shares would have on the market price of our Ordinary Shares.

Following the listing of our Ordinary Shares on the Nasdaq Capital Market in September 2025, we may not be able to meet the continuing listing requirements of the Nasdaq Capital Market and therefore may not be able to have our Ordinary Shares traded on Nasdaq or other national stock exchange in the future.

Our Ordinary Shares have been listed on the Nasdaq Capital Market since September 2025. To maintain this listing, we must continue to satisfy Nasdaq’s ongoing listing standards, including requirements relating to, among other things, minimum bid price, market value of publicly held shares, market value of listed securities, shareholders’ equity, corporate governance, and timely filing of periodic reports with the SEC, as well as other qualitative and quantitative criteria. Our ability to meet these continued listing requirements may be adversely affected by factors outside of our control, including declines in our share price, volatility in the trading market for our Ordinary Shares, reduced investor demand, adverse developments in our business, financial condition, results of operations, liquidity, or prospects, and broader market conditions. In addition, actions we may take to preserve liquidity, pursue financings or strategic alternatives, or restructure operations could negatively affect our ability to satisfy one or more Nasdaq continued listing standards.

Our Ordinary Shares were delisted from the Nasdaq Global Market effective February 25, 2024, which has had, and may continue to have, a material adverse effect on our business and the trading and price of our Ordinary Shares. Any future failure to meet Nasdaq’s continued listing requirements could again materially and adversely affect the liquidity, trading volume, and market price of our Ordinary Shares and could impair our ability to access the capital markets.

If we fail to satisfy Nasdaq’s continued listing requirements, Nasdaq may issue a deficiency notice and we may be afforded a period of time to regain compliance. We may not be able to regain compliance within any applicable cure period or at all. While we may consider available compliance measures, including seeking stockholder approval for corporate actions such as a reverse share split, there can be no assurance that any such measures would be successful, would be implemented in time, or would enable us to maintain our listing on the Nasdaq Capital Market.

If our ordinary shares are delisted from Nasdaq, our securities could be traded on an over-the-counter market (if at all), which would likely result in reduced liquidity, increased price volatility, and a decline in the market price of our ordinary shares. A delisting could also adversely affect our ability to raise additional financing on acceptable terms or at all, increase our cost of capital, limit our ability to use equity as consideration for strategic transactions or compensation, and increase transaction costs and administrative burdens. Further, a delisting could adversely affect investor confidence, the market perception of our Company, and the value of an investment in our Ordinary Shares.

The market price of our Ordinary Shares could fluctuate significantly, which could result in substantial losses for purchasers of our Ordinary Shares.

The stock market in general and the market for smaller technology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, you may lose some or all of your investment. The market price of our Ordinary Shares is affected by the supply and demand for our Ordinary Shares, which may be influenced by numerous factors, many of which are beyond our control, including:

As a result, our share price may be subject to substantial fluctuation.

In addition, general market conditions and fluctuation of share prices and trading volumes could lead to pressure on the market price of our Ordinary Shares, even if there may not be a reason for this based on our business performance or earnings outlook. Prices for companies with a limited operating history, particularly in industries with barriers such as the solar technology and mobility industries, may be more volatile compared to share prices for established companies or companies from other industries. The price of our Ordinary Shares has been volatile since our IPO.

If the market price of our Ordinary Shares declines as a result of the realization of any of these risks, investors could lose part or all of their investment in our Ordinary Shares.

Additionally, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued the shares. If any of our shareholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business, which could significantly harm our profitability and reputation.

Our multiple-class share structure with different voting rights will limit your ability as a holder of Ordinary Shares to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of Ordinary Shares may view as beneficial.

We currently have a multiple-class share structure, as our share capital consists of Ordinary Shares, High Voting Shares and Preferred Shares. In respect of matters requiring the votes of shareholders, holders of Ordinary Shares are entitled to one vote per share, while holders of High Voting Shares are entitled to 25 votes per share. Each High Voting Share is convertible into one Ordinary Share at any time by the holder thereof, while Ordinary Shares are not convertible into High Voting Shares under any circumstances. A holder of Preferred Shares is entitled to 30,000 votes per Preferred Share; provided, however, that if a holder holds shares with an aggregate nominal value exceeding €20,000, such holder can only vote a number of shares equal to 9.99% of the votes attached to all issued and outstanding shares of the Company under our amended articles of association (subject to any contractually agreed voting blocker). This limitation may be lifted by a resolution of the Company’s supervisory board. Further, each Preferred Share is convertible into 30,000 Ordinary Shares at the Effective Conversion Price (as defined below). Ordinary Shares are convertible into Preferred Shares under any circumstances.

As of the date of this Annual Report, all of the issued and outstanding High Voting Shares are held by SVSE. The sole member of SVSE is George O’Leary, the Company’s former Chief Executive Officer and former Managing Director. The current concentration of ownership, if so maintained, may discourage, delay or prevent a change in control of our Company, which could deprive our other shareholders of an opportunity to receive a premium for their Ordinary Shares as part of a sale of our Company and might ultimately affect the market price of our Ordinary Shares. Such concentrated control will limit your ability to influence corporate matters that holders of Ordinary Shares may view as beneficial. In addition, certain index providers, such as S&P Dow Jones or FTSE Russell, view multi-class shares critically and have amended their rules so that companies with multi-class shares will no longer be added to their indexes.

In connection with the Debt Conversion, shareholders at the November 2024 EGM approved the creation of a new class of Preferred Shares in the capital of the Company. As a result of a successful closing of the Debt Conversion, the Company issued 1,401 Preferred Shares to Yorkville and adopted an amendment to its articles of association (the “Articles Amendment”). A Preferred Share is pro rata its nominal value entitled to dividend rights and will have a preferred entitlement upon liquidation of the Company.

Under the terms of the Exchange Agreement, as amended, the Company issued 1,401 Preferred Shares to Yorkville solely in exchange for the surrender and cancellation of all of the debentures held by Yorkville, including the 2022 Debentures, the 2024 Debentures, the New Commitment Debenture and the Advance Debentures. In connection with the conversion of each Preferred Share, the effective conversion price (the “Effective Conversion Price”) per share will be equal to 85% of the lowest daily volume weighted average price of the Ordinary Shares during the 10 trading days immediately preceding the date of the notice of conversion, subject to a floor price equal to (i) $4.00 from the closing date until the end of the day that is six months from the date the Ordinary Shares are listed on the Nasdaq Capital Market, and (ii) $1.00 thereafter. Upon the conversion of each Preferred Share, Yorkville will be required to surrender the Preferred Share being converted, and Yorkville will automatically sell and transfer to the Company for no consideration (the “Repurchase”) additional Preferred Shares such that the total number of Preferred Shares surrendered and subject to the Repurchase will be equal to (a) the total number of Ordinary Shares issuable upon such conversion, multiplied by (b) the Effective Conversion Price, divided by (c) 30,000. Under Dutch corporate law, the Company may not acquire more than half of its nominal share capital. If, as a result of a Repurchase and/or the conversion of High Voting Shares into Ordinary Shares, the Company holds more than half of its nominal share capital, the Company must first take appropriate measures to lower its pro rata percentage of treasury shares. Under the terms of the Exchange Agreement, Yorkville may not convert Preferred Shares if, after giving effect to such conversion, Yorkville and any of its affiliates would beneficially own more than 4.99% of the number or voting power of the Ordinary Shares outstanding immediately after giving effect to such conversion. Such ownership limitations may be waived by Yorkville upon not less than 65 days’ prior notice to the Company. The issuance of Ordinary Shares in connection with conversions of Preferred Shares by Yorkville could cause existing shareholders to experience substantial dilution of their interest in us. See also “Item 1A. Risk Factors—Risks Related to Our Securities—Future offerings of debt or equity securities by us could adversely affect the market price of our Ordinary Shares, and future issuances of equity securities could lead to a substantial dilution of our shareholders”.

As a result of the Debt Conversion and issuance of the Preferred Shares, Yorkville has acquired a large ownership stake in the Company. Furthermore, if Yorkville and SVSE enter into the Call Option Agreement (as defined herein), as currently intended, the Call Option (as defined herein) granted by SVSE to Yorkville would enable Yorkville to acquire an even larger ownership stake in the Company. Under the Call Option Agreement, if executed, Yorkville would have the ability, at its discretion, to purchase all of the Ordinary Shares and High Voting Shares held by SVSE in one or more transactions prior to the Expiration Time (as defined herein), provided that Yorkville may not exercise the Call Option if, after giving effect to such exercise, Yorkville and any of its affiliates would beneficially own more than 4.99% of (i) the number of High Voting Shares outstanding, (ii) the number of Ordinary Shares outstanding, or (iii) the voting power of the total capital of the Company (including due to the voting rights of the High Voting Shares). Such ownership limitations may be waived by Yorkville upon not less than 65 days’ prior notice to the Company. Any increase in Yorkville’s ownership stake in the Company, whether through the issuance of the Preferred Shares and/or any exercise(s) of the Call Option, would further reduce the ability of holders of our Ordinary Shares to influence corporate matters.

Future offerings of debt or equity securities by us could adversely affect the market price of our Ordinary Shares, and future issuances of equity securities could lead to a substantial dilution of our shareholders.

We will require significant additional capital in the future to finance our business operations and growth. For example, we will require additional funding to expand our commercial operations, and we may seek to offer new equity and/or debt in the future for such funding. The Company may seek to raise such capital through the issuance of additional equity or debt securities with conversion rights (e.g., convertible bonds and option rights) or preferred equity (e.g., preference finance shares). An issuance of additional equity, including the issuance of Ordinary Shares in connection with conversions of our Preferred Shares by Yorkville, or debt securities with conversion rights could potentially reduce the market price of our Ordinary Shares, and the Company currently cannot predict the amounts and terms of such future offerings. We expect such funding to be in the form of, or at least include, additional equity and/or debt fundraising, which will dilute existing shareholders.

If such offerings of equity or debt securities with conversion rights are made without granting preemptive rights to our existing shareholders, these offerings would dilute the economic and voting rights of our existing shareholders. Preemptive rights may be restricted or excluded by a resolution of the general meeting or by another corporate body designated by the general meeting. Our supervisory board has been authorized for a period of 18 months following the date of our 2025 annual general meeting which took place on August 13, 2025, or until the next annual general meeting of shareholders (whichever comes first) to issue 105,711,643 shares of our Ordinary Shares and/or grant rights to subscribe for 105,711,643 shares of our Ordinary Shares and to limit or exclude preemptive rights in connection therewith and to issue additional High Voting Shares and/or grant rights to subscribe for such additional High Voting Shares for any legal purpose up to a maximum of 13,400 High Voting Shares and to limit or exclude preemptive rights in connection therewith. All of the foregoing could cause existing shareholders to experience substantial dilution of their interest in us.

In addition, dilution may also arise from (i) the acquisition or investments in companies in exchange, fully or in part, for newly issued Ordinary Shares or High Voting Shares, (ii) conversions by Yorkville of the Preferred Shares and the 2026 Convertible Debentures and the exercise, from time to time, by Yorkville of the Pre-Funded Warrant, (iii) stock options or conversion rights granted to our business partners or our customers as well as from the exercise of stock options or conversion rights granted to our employees in the context of existing or future stock option programs or (iv) the issuance of Ordinary Shares to employees in the context of existing or future employee participation programs.

Any future issuance of Ordinary Shares, High Voting Shares or Preferred Shares could reduce the market price of our Ordinary Shares and dilute the holdings of existing shareholders.

Future sales by major shareholders could materially adversely affect the market price of our Ordinary Shares.

For various reasons, shareholders may sell all or some of our Ordinary Shares, including in order to diversify their investments. Sales of a substantial number of our Ordinary Shares in the public market, or the perception that such sales might occur, could depress the market price of our Ordinary Shares and could impair our ability to raise capital through the sale of additional equity securities.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price for our Ordinary Shares and trading volume could decline.

The trading market for our Ordinary Shares depends in part on the research and reports that securities or industry analysts publish about us or our business. If securities or industry analyst coverage results in downgrades of our Ordinary Shares or publishes inaccurate or unfavorable research about our business, our share price will likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets and demand for our Ordinary Shares could decrease, which, in turn, could cause the market price or trading volume for our Ordinary Shares to decline significantly.

Shareholders may not be able to exercise preemptive rights and, as a result, may experience substantial dilution upon future issuances of Ordinary Shares.

In the event of an issuance of Ordinary Shares, subject to certain exceptions, each shareholder will have a pro rata preemptive right in proportion to the aggregate nominal value of the Ordinary Shares held by such holder. These preemptive rights may be restricted or excluded by a resolution of the general meeting or by another corporate body designated by the general meeting. Our Supervisory Board has been authorized for a period of 18 months following the date of our 2025 annual meeting or until the next annual general meeting of shareholders (whichever comes first) to issue 105,711,643 shares or grant rights to subscribe for 105,711,643 Ordinary Shares and to limit or exclude preemptive rights in connection therewith and to issue additional High Voting Shares and/or grant rights to subscribe for such additional High Voting Shares for any legal purpose up to a maximum of 13,400 High Voting Shares and to limit or exclude preemptive rights in connection therewith. All of the foregoing could cause existing shareholders to experience substantial dilution of their interest in us.

In addition, dilution may also arise from, among other things, (i) the acquisition or investments in companies in exchange, fully or in part, for newly issued Ordinary Shares or High Voting Shares, if issued, (ii) stock options or conversion rights granted to our business partners or our customers as well as from the exercise of stock options or conversion rights granted to our employees in the context of existing or future stock option programs or (iii) the issuance of Ordinary Shares to employees in the context of existing or future employee participation programs.

Furthermore, future conversions of the Preferred Shares to Ordinary Shares could result in substantial dilution to existing shareholders. For more information about the Preferred Shares and the terms of, and limitations on, their conversion, see “Risk Factors—Risks Related to Our Securities—Our multiple-class share structure with different voting rights will limit your ability as a holder of Ordinary Shares to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of Ordinary Shares may view as beneficial.” For additional risks related to dilution, see “Risk Factors—Risks Related to Our Securities—Future offerings of debt or equity securities by us could adversely affect the market price of our Ordinary Shares, and future issuances of equity securities could lead to a substantial dilution of our shareholders.”

We do not expect to pay any dividends in the foreseeable future.

We currently intend to retain our future earnings, if any, for the foreseeable future, to fund our operations as well as the growth of our business. Accordingly, we currently do not intend to pay any dividends to holders of our shares. As a result, capital appreciation in the price of our Ordinary Shares, if any, will be your only source of gain on an investment in our Ordinary Shares.

Risks Related to Our Company’s Status

We have and will continue to incur increased costs as a result of operating as a public company, and our management has and will continue to be required to devote substantial time to new compliance initiatives and corporate governance practices.

As a public company we have and will continue to incur significant legal, accounting and other expenses that we did not incur as a private company, including, but not limited to, costs and expenses for supervisory board members’ fees, increased directors and officers insurance, investor relations and various other costs of a public company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. In addition, during 2024, we determined that the Company no longer qualifies as a foreign private issuer, as defined under the Exchange Act. As a result, effective as of January 1, 2025, the Company is no longer eligible to use the rules designed for foreign private issuers and is instead considered a U.S. domestic issuer. As such, the Company is required to comply with, among other things, U.S. proxy requirements and Regulation FD and its officers, directors and principal shareholders are subject to the beneficial ownership reporting and short-swing profit recovery requirements under Section 16 of the Exchange Act. The Company is also no longer eligible to rely upon exemptions from corporate governance requirements that are available to foreign private issuers or to benefit from other accommodations for foreign private issuers under the rules of the SEC. Further, we are now required to file periodic reports and financial statements prepared in accordance with U.S. GAAP with the SEC on Form 10-K and Form 10-Q, as applicable, as well as current reports on Form 8-K, which are more detailed and extensive than the forms available to a foreign private issuer. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have and will continue to increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance. In addition, we expect to incur additional incremental ongoing costs in connection with becoming a U.S. domestic issuer. The actual amount of the incremental expenses we will incur may be higher, perhaps significantly, from our current estimates for a number of reasons, and there may be additional costs we may incur that we have not currently anticipated.

We are required to comply with Sections 302 and 906 of the Sarbanes-Oxley Act. In addition, pursuant to Section 404(a) of the Sarbanes-Oxley Act, we are required to furnish a report by our management on our internal control over financial reporting annually. While we remain an emerging growth company, we are not required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm pursuant to Section 404(b). We expect that we will cease to be an emerging growth company on December 31, 2026 (the last day of the fiscal year in which the fifth anniversary of the completion of our IPO occurs), at which time we will become subject to additional requirements applicable to non-emerging growth company issuers; however, so long as we continue to qualify as a non-accelerated filer and a smaller reporting company, we will remain exempt from the auditor attestation requirement under Section 404(b). Loss of emerging growth company status, if it were to occur, would increase some of our compliance obligations and costs, but would not, by itself, subject us to Section 404(b) so long as we remain a non-accelerated filer and smaller reporting company.

To achieve compliance with Section 404(a) of the Sarbanes-Oxley Act, we are engaged in documenting and evaluating our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, have engaged outside consultants and are adopting a detailed work plan to assess and document the adequacy of internal control over financial reporting. We will continue to implement steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404(a) of the Sarbanes-Oxley Act. Such conclusion could adversely impact the market price of our Ordinary Shares due to a loss of investor confidence in the reliability of our reporting processes.

Once we are required to include an attestation report on internal control over financial reporting by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes Oxley Act, there is a risk that such independent assessment of the effectiveness of our internal controls over financial reporting could identify material weaknesses that our management’s assessment pursuant to Section 404(a) does not identify.

The consequences of being a public company could have a material adverse effect on our business, financial condition, results of operations and prospects.

Investors may have difficulty enforcing civil liabilities against us or the members of our management and supervisory board or our other officers (functionarissen).

We are organized and exist under the laws of the Netherlands. As such, under Dutch private international law, the rights and obligations of our shareholders vis-à-vis the Company originating from Dutch corporate law and our articles of association, as well as the civil liability of our officers (functionarissen) (including our management board members, supervisory board members and executive officers) are governed in certain respects by the laws of the Netherlands.

We are not a resident of the United States and our officers of Sono Motors GmbH are not residents of the United States. As a result, depending on the subject matter of the action brought against us and/or our officers, United States courts may not have jurisdiction. If a Dutch court has jurisdiction with respect to such action, that court will apply Dutch procedural law and Dutch private international law to determine the law applicable to that action. Depending on the subject matter of the relevant action, a competent Dutch court may apply another law than the laws of the United States.

Also, service of process against non-residents of the United States can in principle (absent, for example, a valid choice of domicile) not be effected in the United States. Furthermore, substantially all of our assets are located outside the United States.

As of the date of this Annual Report, (i) there is no treaty in force between the United States and the Netherlands for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters and (ii) both the Hague Convention on Choice of Court Agreements (2005) and the Hague Judgments Convention (2019) have entered into force for the Netherlands, but have not entered into force for the United States. Consequently, a judgment rendered by a court in the United States will not automatically be recognized and enforced by the competent Dutch courts. However, if a person has obtained a judgment rendered by a court in the United States that is enforceable under the laws of the United States and files a claim with the competent Dutch court, the Dutch court will in principle give binding effect to that United States judgment if (i) the jurisdiction of the United States court was based on a ground of jurisdiction that is generally acceptable according to international standards, (ii) the judgment by the United States court was rendered in legal proceedings that comply with the Dutch standards of proper administration of justice including sufficient safeguards (behoorlijke rechtspleging), (iii) binding effect of such United States judgment is not contrary to Dutch public order (openbare orde) and (iv) the judgment by the United States court is not incompatible with a decision rendered between the same parties by a Dutch court or with a previous decision rendered between the same parties by a foreign court in a dispute that concerns the same subject and is based on the same cause, provided that the previous decision qualifies for recognition in the Netherlands. Even if such a United States judgment is given binding effect, a claim based thereon may, however, still be rejected if the foreign judgment is not or no longer formally enforceable. Moreover, if the United States judgment is not final (for instance when appeal is possible or pending) a competent Dutch court may postpone recognition until the United States judgment will have become final, refuse recognition under the understanding that recognition can be asked again once the United States judgment will have become final or impose as a condition for recognition that security is posted.

A competent Dutch court may deny the recognition and enforcement of punitive damages or other awards. Moreover, a competent Dutch court may reduce the amount of damages granted by a United States court and recognize damages only to the extent that they are necessary to compensate actual losses or damages. Thus, United States investors may not be able, or experience difficulty, to enforce a judgment obtained in a United States court against us or our officers.

The United States and Germany currently do not have a treaty providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. Consequently, a final judgment for payment or declaratory judgments given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in Germany. German courts may deny the recognition and enforcement of a judgment rendered by a U.S. court if they consider the U.S. court not to be competent or the decision to be in violation of German public policy principles. For example, judgments awarding punitive damages are generally not enforceable in Germany. A German court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate for actual losses or damages.

In addition, actions brought in a German court against us, our management board members, our supervisory board members, our senior management and the experts named herein to enforce liabilities based on U.S. federal securities laws may be subject to certain restrictions. In particular, German courts generally do not award punitive damages. Litigation in Germany is also subject to rules of procedure that differ from the U.S. rules, including with respect to the taking and admissibility of evidence, the conduct of the proceedings and the allocation of costs. German procedural law does not provide for pre-trial discovery of documents, nor does Germany support pre-trial discovery of documents under the 1970 Hague Evidence Convention. Proceedings in Germany would have to be conducted in the German language and all documents submitted to the court would, in principle, have to be translated into German. For these reasons, it may be difficult for a U.S. investor to bring an original action in a German court predicated upon the civil liability provisions of the U.S. federal securities laws against us, our management board members, our supervisory board members, our senior management and the experts named in this Annual Report.

Based on the foregoing, there can be no assurance that U.S. investors will be able to enforce against us or management board members, supervisory board members, executive officers, our other officers (functionarissen) or certain experts named herein who are residents of or possessing assets in the Netherlands, Germany and or other countries other than the United States any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.

We are a Dutch public company. The rights of our shareholders may be different from the rights of shareholders in companies governed by the laws of U.S. jurisdictions and may not protect investors in a similar fashion afforded by incorporation in a U.S. jurisdiction.

We are a public company (naamloze vennootschap) organized under the laws of the Netherlands. Our corporate affairs are governed by our articles of association, the rules of our management board and those of our supervisory board and by the laws governing companies incorporated in the Netherlands. However, there can be no assurance that Dutch law will not change in the future or that it will serve to protect investors in a similar fashion afforded under corporate law principles in the United States, which could adversely affect the rights of investors.

The rights of shareholders and the responsibilities of management board members and supervisory board members may be different from the rights and obligations of shareholders and directors in companies governed by the laws of U.S. jurisdictions. In the performance of their duties, our management board members and supervisory board members are required by Dutch law to consider the interests of our Company, its shareholders, its employees and other stakeholders, in all cases with due observance of the principles of reasonableness and fairness. It is possible that some of these parties will have interests that are different from, or in addition to, your interests as a shareholder.

Our articles of association contain exclusive forum provisions for certain claims, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us or the members of our management or supervisory board.

Our articles of association provide that unless we consent in writing to the selection of another forum, the federal district courts of the United States of America will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act or the Exchange Act (the “Federal Forum Provision”). Moreover, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all claims brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Our decision to adopt the Federal Forum Provision followed a decision by the Supreme Court of the State of Delaware holding that such provisions are facially valid under Delaware law. While there can be no assurance that federal or state courts will follow the holding of the Delaware Supreme Court or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision means that suits brought by our shareholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder and our articles of association confirm that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Exchange Act. Accordingly, actions by our shareholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal court.

We may argue that any person or entity purchasing or otherwise acquiring or holding any interest in any of our securities will have, or will be deemed to have, notice of and consented to our exclusive forum provisions, including the Federal Forum Provision. Additionally, our shareholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. These provisions may limit our shareholders’ ability to bring a claim in a judicial forum they find favorable for disputes with us or the members of our management or supervisory board, or employees and agents, which may discourage lawsuits against us and the members of our management or supervisory board or employees and agents.

Alternatively, if a court were to find the choice of forum provision contained in our articles of association to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which may have an adverse effect on our business, financial condition and results of operations.

Provisions of our articles of association or Dutch corporate law might deter acquisition bids for us that might be considered favorable and prevent, delay or frustrate any attempt to replace or remove our management board members or supervisory board members.

Under Dutch law, various protective measures are possible and permissible within the boundaries set by Dutch law and Dutch case law. In this respect, certain provisions of our articles of association may make it more difficult for a third party to acquire control of us or effect a change in our management board and supervisory board. These include:

In addition, Dutch law allows for staggered multi-year terms of our management board members and supervisory board members, as a result of which only part of our management board members and supervisory board members may be subject to appointment or re-appointment in any one year.

Our management board, with the approval of our supervisory board, can - in accordance with Dutch law - invoke a cooling-off period of up to 250 days when shareholders, using their right to have items added to the agenda for a general meeting or their right to request a general meeting, propose an agenda item for our general meeting to dismiss, suspend or appoint one or more management board members or supervisory board members (or to amend any provision in our articles of association dealing with those matters) or when a public offer for our Company is made or announced without our support, provided, in each case, that our management board believes that such proposal or offer materially conflicts with the interests of our Company and its business. During a cooling-off period, our general meeting cannot dismiss, suspend or appoint management board members and supervisory board members (or amend the provisions in our articles of association dealing with those matters) except at the proposal of our management board. During a cooling-off period, our management board must gather all relevant information necessary for a careful decision-making process and at least consult with shareholders representing 3% or more of our issued share capital at the time the cooling-off period was invoked, as well as with our Dutch works council (if we or, under certain circumstances, any of our subsidiaries would have one). Formal statements expressed by these stakeholders during such consultations must be published on our website to the extent these stakeholders have approved that publication. Ultimately one week following the last day of the cooling-off period, our management board must publish a report in respect of its policy and conduct of affairs during the cooling-off period on our website. This report must remain available for inspection by shareholders and others with meeting rights under Dutch law at our office and must be tabled for discussion at the next general meeting. Shareholders representing at least 3% of our issued share capital may submit a request to the Enterprise Chamber of the Amsterdam Court of Appeal (the “Enterprise Chamber”) (Ondernemingskamer), for early termination of the cooling-off period. The Enterprise Chamber must rule in favor of the request if the shareholders can demonstrate that:

We do not comply with all the best practice provisions of the Dutch Corporate Governance Code.

We are subject to the Dutch Corporate Governance Code (“DCGC”). The DCGC contains both principles and best practice provisions on corporate governance that regulate relations between the management board, the supervisory board and the general meeting and matters in respect of financial reporting, auditors, disclosure, compliance and enforcement standards. The DCGC is based on a “comply or explain” principle. Accordingly, companies are required to disclose in their annual reports, filed in the Netherlands, whether they comply with the provisions of the DCGC. If they do not comply with those provisions (for example, because of a conflicting securities exchange requirement), the company is required to give the reasons for such noncompliance. The DCGC applies to Dutch companies listed on a government-recognized stock exchange, whether in the Netherlands or elsewhere. We do not comply with all the best practice provisions of the DCGC and we are not reporting or accounting the best practice provisions that we do comply with. This may affect your rights as a shareholder and you may not have the same level of protection as a shareholder in a Dutch company that fully complies with the DCGC.

We are an “emerging growth company” and a “smaller reporting company,” and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies and smaller reporting companies will make our Ordinary Shares less attractive to investors.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. For so long as we continue to be an emerging growth company, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including not being required to comply with the independent auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and reduced executive compensation disclosure. As a result, our shareholders may not have access to certain information that they may deem important. We expect that we will cease to be an emerging growth company on December 31, 2026 (the last day of the fiscal year in which the fifth anniversary of the completion of our IPO occurs), although circumstances could cause us to lose that status earlier, including if our total annual gross revenue exceeds $1.235 billion, if we issue more than $1.00 billion in non-convertible debt securities during any three-year period, or if we are a large accelerated filer and the market value of our Ordinary Shares held by non-affiliates exceeds $700 million as of the end of any second quarter before that time.

We are also a “smaller reporting company,” as defined in the Exchange Act. Even after we no longer qualify as an “emerging growth company,” we may still qualify as a “smaller reporting company,” which would allow us to continue to take advantage of many of the same exemptions from disclosure requirements, including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our Ordinary Shares less attractive because we may rely on these exemptions and reduced disclosure requirements. If some investors find our Ordinary Shares less attractive, as a result, there may be a less active trading market for our Ordinary Shares and the price of our Ordinary Shares may be more volatile.

Our ability to use our net operating loss carryforwards and other tax attributes may be limited.

Our ability to utilize our net operating loss carryforwards is currently limited, and may be limited further, under Section 8c of the German Corporation Income Tax Act (Körperschaftsteuergesetz) (the “KStG”) and Section 10a of the German Trade Tax Act (Gewerbesteuergesetz) (the “GewStG”). These limitations apply if a qualified ownership change, as defined by Section 8c of the KStG, occurs and no exemption is applicable.

Generally, a qualified ownership change occurs if more than 50% of the share capital or the voting rights are directly or indirectly transferred to a shareholder or a group of shareholders within a period of five years. A qualified ownership change may also occur in case of a transaction comparable to a transfer of shares or voting rights or in case of an increase in capital leading to a respective change in the shareholding.

In the case of such a qualified ownership change tax loss carryforwards expire in full. To the extent that the tax loss carryforwards do not exceed the built-in gains (stille Reserven) in the assets and liabilities taxable in Germany, they may be further utilized despite a qualified ownership change. In case of a qualified ownership change within a group, tax loss carryforwards will be preserved if certain conditions are satisfied. In case of a qualified ownership change, tax loss carryforwards will be preserved (in the form of a “fortführungsgebundener Verlustvortrag”) if the business operations have not been changed and will not be changed within the meaning of Section 8d of the KStG.

According to an appeal filed by the fiscal court of Hamburg dated August 29, 2017, Section 8c, paragraph 1, sentence 1 of the KStG is not in line with the German constitution. The appeal is still pending. It is unclear when the Federal Constitutional Court will decide this case.

As of December 31, 2025, there were net operating loss carryforwards of the Subsidiary for German corporate tax purposes of €39.0 million and for German trade tax purposes of €38.0 million available. The contribution of 100% of the Subsidiary’s shares into the Company was qualified as an ownership change within the meaning of Section 8c of the KStG and Section 10a of the GewStG. Furthermore, the termination of the Sion passenger car program in February 2023 was considered a harmful event within the meaning of Section 8d, paragraph 2 of the KStG. As a result, the available tax loss carryforwards of the Subsidiary would generally expire in full. However, the net operating loss carryforwards would not be forfeited to the extent that the Subsidiary has built-in gains in its assets that are fully taxable in Germany. The built-in gains are determined by comparing the fair market value of the respective entity with the entity’s tax book equity. The built-in gains as of December 31, 2025 have not yet been determined. Therefore, it is currently unclear whether all tax losses can still be carried forward.

Future changes in share ownership may also trigger an ownership change and, consequently, a Section 8c KStG or a Section 10a GewStG, limitation. Any limitation may result in the expiration of a portion or the complete tax operating loss carryforwards before they can be utilized. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards to reduce German income tax may be subject to limitations, which could potentially result in increased future cash tax liability to us.

Market for Ordinary Shares

Our Ordinary Shares are listed on the Nasdaq Stock Market LLC, and commenced trading on the Nasdaq Capital Market under the symbol “SSM” on September 5, 2025. From November 17, 2021 through February 25, 2024, our Ordinary Shares were listed on the Nasdaq Global Market under the symbol “SEV.” On July 21, 2023, trading of our Ordinary Shares on the Nasdaq Global Market was suspended. On December 11, 2023, we received a decision of the Panel advising us that the Panel had determined to delist the Ordinary Shares from the Nasdaq Global Market. Nasdaq filed a Form 25 Notification of Delisting with the SEC on February 15, 2023 to complete the delisting. On July 2, 2024 our Ordinary Shares commenced quoting on OTCQB under the ticker symbol “SEVCF” and continued to be quoted on OTCQB until September 5, 2025 when our Ordinary Shares commenced trading on the Nasdaq Capital Market as described above.

Record Holders

As of March 25, 2026, there were 15 holders of record of our Ordinary Shares, one of which was Cede & Co., a nominee for Depository Trust Company (“DTC”), one holder of record of our High Voting Shares and one holder of record of our Preferred Shares. Ordinary Shares that are held by financial institutions as nominees for beneficial owners or in “street name” are deposited into participant accounts at DTC and are considered to be held of record by Cede & Co. as one shareholder.

Dividends

To date, we have not paid any dividends on our shares, and we do not anticipate paying any cash dividends on our shares in the foreseeable future. We intend to retain all available funds and any future earnings to fund the development and expansion of our business. As a Dutch entity and under Dutch law, we may only pay dividends to the extent our shareholders’ equity (eigen vermogen) exceeds the sum of the paid-in and called-up share capital plus the reserves required to be maintained by Dutch law or by our articles of association and (if it concerns a distribution of profits) after adoption of the annual accounts by the general meeting from which it appears that such dividend distribution is allowed. Subject to such restrictions, any future determination to pay dividends or other distributions from our reserves will be at the discretion of our management board with the approval of our supervisory board and will depend upon a number of factors, including our results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law and other factors our management board and supervisory board deem relevant.

You should read the following discussion and analysis of our financial condition and results of operations together with our audited consolidated financial statements and related notes included elsewhere in this Annual Report. This discussion contains forward-looking statements based upon current plans, expectations and beliefs involving risks and uncertainties, as well as assumptions, that if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” and in other parts of this Annual Report. 

Overview

For the year ended December 31, 2025, we were a technology company focused on the development and commercialization of solar integration solutions for commercial vehicles. Our proprietary solar charge controller (MCU) technology enabled the seamless integration of solar energy into high- and low-voltage vehicle architectures, reducing fuel consumption and emissions for diesel-powered vehicles and extending battery life for electric vehicles. Subsequent to December 31, 2025, the Company adopted the Treasury Strategy and initiated an exit from its legacy solar operations.

Our product portfolio includes complete solar solutions for refrigerated trailers, electric buses, commercial vans and trucks, as well as standalone components, such as solar charge controllers (MCUs) and solar modules. We also provide engineering services to assist OEMs and fleet operators in integrating solar technology into their vehicle production processes.

Since our pivot to solar-only solutions in early 2023, we have continued to refine and expand our offerings, with an increased focus on OEM partnerships to drive adoption of factory-installed solar solutions. While we have generated limited revenue to date, we believe that our technology has large market potential in addressing the growing demand for cost-saving and emission-reducing energy solutions for commercial fleets.

Historically, we have incurred operating losses since our inception; however, in 2024, we recorded an operating profit due to the impact of revaluation gains following the reconsolidation of Sono Motors GmbH after the termination of the Self-Administration Proceedings in early 2024. This one-time accounting impact significantly influenced our reported net income for the year ended December 31, 2024. In 2025, we recorded an operating loss of €7.7 million, although our net income for the same period was positive and amounted to €4.0 million, primarily due to recorded gains in the fair value of convertible debentures carried at fair value.

Subsequent to December 31, 2025, we implemented a series of actions that we believe fundamentally alter our cost structure and liquidity profile on a going-forward basis. In March 2026, we raised gross proceeds of approximately $5.0 million, consisting of a $3.0 million convertible debenture and a pre-funded warrant issued in a private placement for aggregate proceeds of approximately $2.0 million, adopted our Treasury Strategy and entered into an institutional framework with Blockchain.com (BVI) II Limited in the form of the ISDA Master Agreement and the related Schedule and Credit Support Annex, to facilitate related derivative and hedging transactions in connection with our digital asset holdings, and terminated current and future funding commitments to the Subsidiary (Sono Motors GmbH) and initiated our exit from the legacy solar operations conducted through the Subsidiary, which is expected to materially reduce the Company’s ongoing cash outflows. Management believes these actions, taken together, may provide sufficient resources to fund our streamlined operating plan for at least twelve months from the date the financial statements are issued. However, our ability to maintain adequate liquidity remains subject to significant uncertainties, including the price volatility and liquidity characteristics of digital assets, the potential collateral requirements under our Treasury Strategy, the timing and costs associated with exiting our legacy solar operations, which we are currently unable to estimate, and the maturity of our outstanding convertible debenture in March 2027. See “Liquidity Outlook and Ability to Continue as a Going Concern” below.

As of December 31, 2025, we operated as a single business segment, managing our financing, research and development and product commercialization on a consolidated basis. Our financial results reflect a transition from pre-revenue technology development to commercial-scale implementation, and we expect continued volatility as we scale operations.

Subsequent to December 31, 2025, we determined in the first quarter of fiscal 2026 to adopt the Treasury Strategy and exit our legacy solar business, as described above. See “—Recent Developments” below for additional information.

Components of our Results of Operations

Revenue

Historically, our revenue has been derived primarily from prototype sales and pilot installations of our solar retrofit solutions, including the Solar Bus Kit, across commercial vehicle categories such as buses, trucks, refrigerated trailers and electric vans. We have not generated material revenue from our solar technology solutions to date, and revenue for the year ended December 31, 2025 remained limited, reflecting the early-stage nature of our commercial deployments.

Subsequent to December 31, 2025, following our adoption of the Treasury Strategy and the initiation of our exit from legacy solar operations, we do not expect to generate revenue from solar technology activities in future periods. Going forward, the Company's financial performance will depend principally on the cash flows generated through the Treasury Strategy rather than product or service revenues.          

Cost of Sales

For the year ended December 31, 2025, we incurred limited cost of sales, reflecting the limited initial revenue generation from prototype projects and early-stage product deployments. Our cost of sales consisted  mostly of material costs and personnel expenses. Subsequent to December 31, 2025, following our adoption of the Treasury Strategy and the initiation of our exit from legacy solar operations, we do not expect to incur any cost of sales in future periods.

Research and Development Expenses

We did not record research expenses in prior years, as we did not engage in fundamental research activities. Our development expenses primarily consist of (i) personnel expenses for our development team, including salaries, bonuses and related share-based compensation, (ii) costs associated with prototype development and solar integration, (iii) professional services and (iv) other expenses. Development costs are expensed as incurred, as the recognition criteria for capitalization have not been met. In 2025, research and development expenses increased, reflecting our technology optimization efforts as well as efforts directed on establishing long-term partnerships and collaborations with OEMs. Subsequent to December 31, 2025, following our adoption of the Treasury Strategy and the initiation of our exit from legacy solar operations, we do not expect to incur any research and development expenses in future periods

Selling and Distribution Expenses

We recognize selling and distribution expenses on an accrual basis when incurred. These expenses primarily include personnel expenses associated with our sales and business development functions, advertising and marketing costs incurred in connection with promoting our solar technology solutions and establishing new commercial partnerships, and other selling-related costs. Subsequent to December 31, 2025, following our adoption of the Treasury Strategy and the initiation of our exit from legacy solar operations, we anticipate selling and distribution expenses to decrease significantly in future periods as commercial activities associated with our solar technology business are wound down.

General and Administrative Expenses

We recognize general and administrative expenses on an accrual basis when incurred. These expenses primarily include professional fees (comprising consultant, legal, audit and compliance costs), personnel costs, insurance, software fees and subscriptions, and other general overhead costs. As a public company listed on the Nasdaq Capital Market, we also incur ongoing costs related to regulatory compliance, financial reporting, investor relations and corporate governance. We anticipate general and administrative expenses to continue to reflect the costs associated with maintaining our public company infrastructure and supporting our broader operational and strategic objectives.

Other Operating Income/Expenses

Other operating income primarily includes government grants and any non-recurring income. Other operating expenses mainly consist of foreign exchange losses from currency conversions and other non-operating costs. These items may vary from period to period depending on external factors such as exchange rate fluctuations and grant allocations.

Gain from Reconsolidation of Subsidiary

On February 29, 2024, the Subsidiary exited its Self-Administration Proceedings via the Plan. As a result, all outstanding debts between the Company and the Subsidiary were extinguished, and the Subsidiary was reconsolidated into our consolidated financial statements effective March 1, 2024.

The reconsolidation resulted in a net gain of approximately €62.6 million, reflecting the revaluation of the Subsidiary’s net assets and the extinguishment of parental guarantees and related liabilities. This gain is recorded in our 2024 operating results and represents the financial impact of regaining control over the Subsidiary.

While this gain had a significant positive effect on our reported 2024 operating results, it does not reflect ongoing business operations or recurring profitability. We expect that our future financial performance will depend principally on the cash flows generated through the Treasury Strategy. In line with these expectations there was no gain from reconsolidation recorded for the fiscal year ended December 31, 2025.

Interest and Similar Expenses

Interest expenses primarily consist of costs associated with interest-bearing liabilities, including convertible debentures and other financing instruments used to support our operations. These expenses reflect the cost of capital required to fund our business activities and ongoing development efforts.

Results of Operations

The following table summarizes our consolidated results of operations for the periods indicated:

Revenue

For the year ended December 31, 2025, we recorded €149 thousand of revenue, while for the year ended December 31, 2024, we recorded no revenue. Our focus during these periods was on refining our solar technology, obtaining regulatory approvals and securing strategic partnerships. While we have successfully developed and tested our ViPV solutions and solar charge controllers, commercial-scale adoption and revenue generation are expected to develop and evolve in future periods as we transition from pilot projects to broader market deployment.

Cost of Sales

For the year ended December 31, 2025, we recorded cost of sales in the amount of €92 thousand. For the year ended December 31, 2024, we recorded no cost of sales, as we did not generate revenue during this period.

Research and Development Expenses

For the year ended December 31, 2025, cost of development expenses increased to approximately €1,817 thousand from €1,118 thousand for the year ended December 31, 2024, representing a growth of 63%. The increase primarily reflects our technology optimization efforts, efforts directed on establishing long-term partnerships and collaborations with OEMs, as well as specific improvements and refinements to our solar technology.

Selling and Distribution Expenses

For the year ended December 31, 2025, Selling and Distribution expenses amounted to €877 thousand, compared to €678 thousand for the year ended December 31, 2024, representing a growth of 29%. The increase is primarily attributable to higher personnel expenses of €128 thousand, reflecting the expansion of our commercialization efforts, as well as an increase in advertising and marketing costs of €53 thousand driven by our expanded efforts to establish new partnerships and pursue new project opportunities.

General, and Administrative Expenses (G&A)

For the year ended December 31, 2025, G&A expenses totaled approximately €5,073 thousand, compared to €4,648 thousand for the year ended December 31, 2024, representing an increase of 9%. The increase was primarily driven by a growth in professional fees and software fees and subscriptions.

The largest components of G&A expenses in 2025 were payroll and social contributions, and legal, audit and other advisory services, similar to our 2024 G&A expenses structure.

Other Operating Income/Expenses

For the year ended December 31, 2025, other operating income and other operating expenses resulted in a net balance of approximately €13 thousand. For the year ended December 31, 2024, other operating income and expenses resulted in a net balance of approximately €398 thousand. The decrease of approximately €385 thousand, or 97%, was primarily attributable to a significant reduction in government grants recognized during 2025 compared to 2024, which had been a principal contributor to other operating income in the prior year.

Gain (Loss) on reconsolidation

For the year ended December 31, 2025, there was no gain or loss recorded in connection with the reconsolidation of the Subsidiary, since the reconsolidation was finalized in 2024.

For the year ended December 31, 2024, we recognized a gain of approximately €62.6 million in connection with the reconsolidation of the Subsidiary following its exit from its Self-Administration Proceedings. This gain primarily reflected the extinguishment of certain liabilities and the re-recognition of net assets upon regaining control of the Subsidiary.

Income from changes in fair value of convertible notes payable carried at fair value

For the year ended December 31, 2025, we recorded a gain of approximately €11,108 thousand from the fair value measurement of financial liabilities. This gain primarily relates to the revaluation of convertible debentures issued in connection with our financing arrangements, which are accounted for at fair value through profit or loss under U.S. GAAP.

For the year ended December 31, 2024, we recognized a gain of approximately €8,923 thousand from the fair value measurement of financial liabilities. This gain primarily relates to the revaluation of convertible debentures issued in connection with our financing arrangements, which are accounted for at fair value through profit or loss under U.S. GAAP.

Gain (Loss) on Foreign Currency Translation

For the year ended December 31, 2025, we recorded a foreign currency translation gain of approximately €604 thousand, primarily resulting from favorable exchange rate movements impacting Euro-denominated balances. We recognized a foreign currency translation loss of approximately €405 thousand for the year ended December 31, 2024.

Net Income

For the year ended December 31, 2025, we reported net income of €4,015 thousand, marking a significant decrease from the net income of €65,026 thousand recorded for the year ended December 31, 2024. While net income for the year ended December 31, 2024 was driven by the gain from the consolidation of the Subsidiary as well as by the income from changes in fair value of convertible debt carried at fair value, in the year ended December 31, 2025 we recorded no gains on reconsolidation and the net income for this period is attributed mostly to the income from changes in fair value of convertible debt carried at fair value.

For the year ended December 31, 2025, we reported an operating loss of €7,697 thousand, reflecting the early-stage nature of our business and investments in technology development, commercialization and operational scaling.

Looking ahead, subsequent to December 31, 2025, the Company adopted the Treasury Strategy and initiated an exit from its legacy solar operations. As a result, we anticipate that future operating losses will be materially reduced compared to historical periods, as the primary source of our historical cash consumption has been eliminated. Our long-term financial performance will depend on the successful implementation of the Treasury Strategy, the cash flows generated through our digital asset holdings, and efficient management of our streamlined holding company cost structure. There can be no assurance that the Treasury Strategy will generate the anticipated returns or that additional financing will not be required. See "Liquidity Outlook and Ability to Continue as a Going Concern" below and “Note 16 Subsequent Events” for additional information..

Liquidity and Capital Resources

As of December 31, 2025, our cash was €206 thousand, compared to €1,354 thousand as of December 31, 2024. Cash consists of cash in bank accounts.

We have not generated material revenue from operations and we continue to incur operating expenses related to our holding company overhead and public company compliance costs. Following the adoption of the Treasury Strategy and the cessation of funding to the Subsidiary (Sono Motors GmbH) in the first quarter of 2026, our liquidity position is principally dependent on the performance of our digital asset holdings and the cash flows generated through the Treasury Strategy, supplemented as necessary by external financing, including equity and equity-linked financings and debt instruments.

Sources and Uses of Liquidity

Historically, we have financed our operations through:

Our cash outflows have primarily been driven by:

Liquidity Outlook and Ability to Continue as a Going Concern

The Company has incurred recurring operating losses and negative cash flows from operations since inception, primarily attributable to the operations of its solar technology subsidiary, Sono Motors GmbH. For the year ended December 31, 2025, the Company recorded a net operating loss of €7.7 million and negative operating cash flows of €7.3 million, and as of December 31, 2025 had an accumulated deficit of €317.4 million. These conditions raise substantial doubt about the Company’s ability to continue as a going concern.

Subsequent to December 31, 2025, the Company has implemented a series of actions intended to improve liquidity and reduce ongoing cash requirements. These actions, which are more fully described in “Item 17 – Subsequent Events” of Part II, Item 8 of this Annual Report, included: (i) raising gross proceeds of approximately $5.0 million in March 2026, consisting of a $3.0 million convertible debenture and a pre-funded warrant issued in a private placement for aggregate proceeds of approximately $2.0 million; (ii) adopting the Treasury Strategy, and entering into an institutional framework with Blockchain.com (BVI) II Limited in the form of the ISDA Master Agreement and the related Schedule and Credit Support Annex, to facilitate related derivative and hedging transactions in connection with the Company’s digital asset holdings; and (iii) terminating current and future funding commitments to the Subsidiary (Sono Motors GmbH) and initiating our exit from the legacy solar operations conducted through the Subsidiary, which is expected to materially reduce the Company’s ongoing cash outflows. Management believes that these actions, taken together, may provide sufficient resources to fund the Company’s streamlined operating plan under the Treasury Strategy, consisting principally of holding company overhead and public company compliance costs, for at least twelve months from the date the financial statements are issued.

However, the Company’s ability to maintain adequate liquidity remains subject to significant uncertainties, including, among other things, the price volatility and liquidity characteristics of digital assets, the terms and potential collateral requirements of transactions entered into in connection with the Treasury Strategy, the timing and costs associated with exiting the legacy solar operations (which the Company is currently unable to estimate), and that the Company’s outstanding convertible debenture issued to Yorkville in the first quarter of fiscal 2026 will reach maturity in March 2027, which may require us to negotiate a refinancing or conversion of the debenture prior to or at maturity.

See “Note 16 – Subsequent Events” in Part II, Item 8 of this Annual Report for information regarding our financing arrangements with Yorkville subsequent to the fiscal year ended December 31, 2025.

Cash Flows

The table below summarizes our cash flows provided by / (used in) operating, investing and financing activities for the years ended December 31, 2025 and 2024.

Net cash used in operating activities

Net cash used in operating activities decreased from €14,284 thousand in the year ended December 31, 2024 to €7,254 thousand in the year ended December 31, 2025. The decrease was primarily driven by lower cash outflows related to changes in working capital.

Net cash used in investing activities

We had no investing activities during the year ended December 31, 2025. Net cash provided by investing activities was €1,226 thousand in the year December 31, 2024, primarily attributable to the reconsolidation of the Subsidiary cash balance.

Net cash from (used in) financing activities

Net cash provided by financing activities was €6,078 thousand in the year ended December 31, 2025, resulting primarily from proceeds received in connection with the issuance of convertible notes. For the year ended December 31, 2024, net cash provided by financing activities was €7,000 thousand, resulting from proceeds received in connection with the issuance of convertible notes.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. GAAP.

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. We base our estimates on historical experience, known trends and other market-specific or relevant factors that we believe to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates when there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. If actual results differ from our estimates, or to the extent these estimates are adjusted in future periods, our results of operations could either benefit from or be adversely affected by any such change in estimate.

Our most critical accounting estimate is our fair value assessments of financial instruments. Changes in these estimates and assumptions could materially affect our reported results. For instance, a change in the estimated fair value of financial instruments could result in significant variations in net income.

See Note 2 to our consolidated financial statements included in Part II, Item 8 of this Annual Report for a summary of significant accounting policies and the effect on our consolidated financial statements.

Recent Developments

Digital Asset Treasury Strategy

In the first quarter of fiscal 2026, we adopted and approved a digital asset treasury strategy and digital asset treasury policy and the purchase by the Company of Bitcoin and other digital assets in connection therewith (the “Treasury Strategy”). Under the Treasury Strategy, the principal holding in the Company’s treasury reserve on its balance sheet will be allocated to digital assets, principally Bitcoin, by applying a covered-call yield strategy. The Company may use available liquidity, including proceeds from previously disclosed financing arrangements, to purchase Bitcoin and other digital assets, subject to applicable law and public disclosure requirements. The Company intends to solicit the ratification by its shareholders of the engagement by the Company in the Treasury Strategy, as previously disclosed.

Exit from Sono Motors GmbH

On March 14, 2026, our supervisory board resolved to terminate all current and future funding commitments to the Subsidiary and to exit the legacy solar operations conducted through the Subsidiary, with immediate effect. The Company’s decision was driven by the Subsidiary’s historical lack of profitability, which has resulted in the Company having to continuously provide funding to the Subsidiary, and thus incur losses, and a determination by the supervisory board that there was not a clear path for the Subsidiary to achieve profitability in a reasonably desirable timeframe and thus, avoid future losses by the Company. This decision was made in conjunction with the decision on March 14, 2026 by our management board, with the approval of the supervisory board, to adopt the Treasury Strategy, as previously announced. The Treasury Strategy is projected to generate cash flow for the Company in the first year of its execution. The Company is also exploring other strategic alternatives to maximize shareholder value.

The Company is currently unable to make a good faith estimate of the total costs and charges, if any, that may be incurred in connection with the cessation of funding to the Subsidiary and the exit from the Company’s legacy solar business. The determination of any such costs is subject to significant uncertainties, including, among other things, the timing, scope and manner of any actions undertaken with respect to the Subsidiary following the cessation of funding, as well as the extent of any obligations of the Company in connection therewith. Potential costs, if any, may include legal, advisory and other professional fees and expenses associated with activities relating to the Subsidiary. Any such costs and expenditures, if incurred, are expected to be reduced by cash flow to the Company from the Treasury Strategy.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report, our management team, with the participation of our principal executive officer and principal financial officer, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our principal executive officer and principal financial officer concluded that, due to the unremediated material weakness in our internal control over financial reporting as described below, our disclosure controls and procedures were not effective as of December 31, 2025.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Our management assessed the effectiveness of our internal control over financial reporting based on the criteria set forth in “Internal Control - Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In previous years' audits, the material weaknesses that were identified relate to: (i) a lack of consistent and proper application of processes and procedures; (ii) the design and operating effectiveness of information technology general controls for information systems that are significant to the preparation of our consolidated financial statements; (iii) a lack of review and supervision; (iv) the sufficiency of resources with an appropriate level of technical accounting and SEC reporting experience; and (v) clearly defined control processes, roles and segregation of duties within our finance and accounting functions.

In light of the Companies’ successful emergence from their respective Self-Administration Proceedings and the restructuring/recapitalization of our businesses, we are currently planning measures to remedy such material weaknesses. Beginning January 1, 2025, the planned remedial measures began with the hiring of additional accounting staff and the appointment of a new chief financial offer who possess the requisite skills to address technical accounting and reporting issues and implement processes that include taking steps to improve our controls and procedures. We continue to devote attention to remediating the aforementioned deficiencies and specifically have incorporated automated and software-based accounting tools, engage third parties to support our internal resources related to accounting and internal controls, implement ongoing internal training for our accounting and finance teams and continue to invest in our finance IT systems. However, as of December 31, 2025, we are still in the process of remediating the previously identified material weaknesses.

Based upon the above evaluation, management, including our Chief Executive Officer and Chief Financial Officer, concluded that our internal control over financial reporting was not effective as of December 31, 2025, due to the presence of multiple material weaknesses as described above. Notwithstanding these material weaknesses, our management, based on the substantial work performed, concluded that our consolidated financial statements for the periods covered by and included in this Annual Report are fairly stated in all material respects in accordance with U.S. GAAP.

Attestation Report of the Registered Public Accounting Firm

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm because, as an “emerging growth company”, we are exempt from Section 404(b) of the Sarbanes-Oxley Act of 2002.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the quarter ended December 31, 2025 that has materially affected or is reasonably likely to materially affect our internal control over financial reporting.

Limitations on Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs. 

Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections.

Not applicable.

Following the restructuring of the Companies as a result of the former Self-Administration Proceedings and the corporate measures implemented in connection therewith, there is uncertainty over the future of the remuneration based on shares (share-based payment) programs, which may result in share options not being formally granted or, in some cases, cancellation of unexercised options, which may be done without compensation.

Long-Term Incentive Plan (LTIP)

In November 2021, in conjunction with the consummation of our IPO, we established a new long-term incentive plan (the “LTIP”) with the purpose of advancing the interests of our shareholders and other stakeholders by enhancing our ability to attract, retain and motivate individuals who are expected to make important contributions to us. The LTIP governed issuances of equity and equity-based incentive awards from and after the consummation of our IPO. The maximum number of ordinary shares underlying awards granted pursuant to the LTIP (other than replacement awards under the LTIP) was not to exceed 10% of the Company’s issued share capital from time to time. The Company does not currently grant awards under LTIP or CSOP (as defined below) and currently does not intend to grant awards under the LTIP or CSOP in the future.

The LTIP was, as applicable, administered by (i) the management board, to the extent the administration or operation of the LTIP related to the grant of awards to a participant who was not a management board member or supervisory board member, as well as any other matter relating to such awards, (ii) the Company’s supervisory board, to the extent the administration or operation of the LTIP related to the grant of awards to participants who were members of the compensation committee established by the supervisory board, as well as any other matter related to such awards, or (iii) the compensation committee established by the supervisory board for all other matters related to the administration or operation of the LTIP (each of these bodies, where appropriate, the “Committee”).

Awards under the LTIP could be granted to our employees, the members of our management board and supervisory board, consultants or other advisors.

Awards under the LTIP could be granted in the form of stock options, stock appreciation rights, shares of restricted stock, restricted stock units, other share-based awards or a combination of the foregoing. The Committee had the ability to condition the right of an individual to exercise his or her awards upon the achievement or satisfaction of performance criteria.

In the event of a good leaver’s (as defined in the LTIP) termination of employment or service, all vested awards must be exercised or settled in accordance with their terms within a period specified by the Committee and all unvested awards shall be canceled automatically without compensation unless otherwise determined by the Committee or set forth in the applicable award documentation. In the event of a bad leaver’s (as defined in the LTIP) termination of employment or service, all vested and unvested awards will be canceled automatically without compensation.

In the event of a change in control (as defined in the LTIP) of the Company outstanding awards that are substituted or exchanged for equivalent replacement awards will be canceled. If outstanding rewards are not substituted or exchanged for equivalent replacement awards, the awards shall immediately vest and settle in full, unless otherwise decided by the Committee.

Conversion Stock Option Program (CSOP)

In December 2020, against the background of our intention to terminate all relevant benefits under former employee participation programs from 2017 and 2018 (respectively, the “VESP 2017” and “VESP 2018”) pursuant to which employees were granted virtual shares, we adopted our conversion stock option program (“CSOP”) under the LTIP in order to grant a total of 41,157 of stock options, each with an exercise price of €4.50, to the former beneficiaries under the VESP 2017 (except for one such beneficiary) and the VESP 2018, as well as one additional beneficiary, based on individual grant agreements.

Under the CSOP, the Company granted 31,948 fully vested stock options, each with an exercise price of €4.50 and which are not subject to any performance criteria, with effect as of the closing date of our IPO on November 19, 2021 to all former beneficiaries under the VESP 2017 (except for one beneficiary who had not accepted our offer to transfer to the CSOP), as well as the one aforementioned additional beneficiary (the “VESP 2017 Tranche”).

The VESP 2017 Tranche stock options became exercisable one year after the closing of our IPO and are exercisable only in certain windows. The VESP 2017 Tranche stock options expired on November 18, 2025, four years after the closing of our IPO.

In addition, the Company granted 9,209 stock options (as of June 2023 all these stock options were fully vested), each with an exercise price of €4.50 and which are not subject to any performance criteria, with effect as of the closing date of our IPO on November 19, 2021 to the former beneficiaries under the VESP 2018 (the “VESP 2018 Tranche”). The VESP 2018 Tranche stock options are generally subject to a three-year vesting period with 1/36 of the stock options granted to the relevant beneficiary incrementally vesting for each month of employment of such beneficiary depending on the relevant vesting start date as set out in the relevant individual grant agreement. The then-vested VESP 2018 Tranche stock options became exercisable one year after the closing of our IPO and are exercisable only in certain windows. The VESP 2018 Tranche stock options expired on November 18, 2025, four years after the closing of our IPO.

Restricted Stock Units

Certain former supervisory board members received one-time awards of restricted stock units for Ordinary Shares (“RSUs”) under the LTIP in connection with the Company’s IPO and such individual’s appointment as a member of the supervisory board, starting from the date of the Company’s IPO. The awards were granted on November 21, 2021 and vest in four equal, annual installments on each anniversary of the grant date, with the fourth installment vesting on the earlier of (a) the fourth anniversary of the grant date or (b) the Company's annual general meeting of shareholders to be held in 2025. The number of RSUs, presented in the table below, represent the amount vested up to the respective resignation date.

Item 13. Certain Relationships and Related Transactions, and Director Independence.

The following is a summary of transactions since January 1, 2024, to which we have been a participant in which the amount involved exceeded or will exceed the lesser of $120,000 or one percent of the average of our total assets at year-end for the last two completed fiscal years, and in which any of our supervisory board members, management board members, executive officers or holders of more than five percent of any class of our voting securities, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest, other than compensation arrangements which are described in “Executive Compensation” in Item 11 of Part III of this Annual Report.

Agreements with Yorkville

Yorkville Restructuring Investment

In the context of the former Self-Administration Proceedings and in connection with the First Commitment, the Companies entered into the Yorkville Investment Agreements with Yorkville in mid-November 2023, and on April 30, 2024, the Company and Yorkville entered into an amendment to the Funding Commitment Letter in connection with the Second Commitment. Pursuant to the Yorkville Investment Agreements, Yorkville committed to provide financing to the Company, subject to the Companies’ continued compliance with the terms of the Yorkville Investment Agreements. For more information, see “Item 1. Business—Financing Arrangements with Yorkville—The Yorkville Restructuring Investment”. Under the terms of the Funding Commitment Letter, funding from Yorkville in connection with the Yorkville Investment was provided by way of new interest-bearing convertible debenture(s). The 2024 Debentures with respect to the First Tranche of the Yorkville Restructuring Investment was issued to Yorkville on February 6, 2024 for approximately $4.3 million and the convertible debenture with respect to the Second Tranche was issued to Yorkville on August 30, 2024 for approximately $3.3 million.

In connection with the Funding Commitment Letter, SVSE and Yorkville entered into both a pledge agreement (the “Pledge Agreement”) and a security agreement (the “Security Agreement”), each dated February 5, 2024, pursuant to which SVSE agreed to pledge and grant to Yorkville, as a third-party pledge, a security interest in certain financial assets, including, among others, all of the Ordinary Shares and High Voting Shares that SVSE currently holds or at any time acquires (collectively, the “Pledged Ownership Interests”). The Pledged Ownership Interests serve as collateral for the repayment of the Company’s obligations to Yorkville. In the event that the Company is in default of its payment obligations to Yorkville, following notification thereof to SVSE, the voting rights and dividend rights in the Pledged Ownership Interests would accrue to Yorkville. In certain instances, Yorkville may also have the right to enforce its right of pledge and sell the Pledged Ownership Interests, thereby using the proceeds from the sale to repay the amounts owed by the Company to Yorkville.

On June 20, 2024, in connection with the Yorkville Restructuring Investment, the Subsidiary and SVSE entered into a guaranty agreement (the “Guaranty”) for the benefit of Yorkville. Under the terms of the Guaranty, each of the Subsidiary and SVSE have agreed, among other things (i) to jointly and severally guarantee the payment of obligations owed by the Company to Yorkville in full when due and (ii) to guarantee the performance of all of the terms, covenants and conditions required to be kept, observed or performed by the Company in the Guaranty, the Funding Commitment Letter, the new convertible debentures, the Security Agreement and the Pledge Agreement. The Guaranty is irrevocable, absolute and unconditional and applies to all obligations owed by the Company to Yorkville whenever arising. Under the terms of the Guaranty, certain events of default would enable Yorkville, at its option and in its discretion, to accelerate some or all of the obligations so that they become immediately due and payable.
