Ads-Tec Energy Public Ltd Co

ADS-TEC Energy PLC (ADSE) operates in the evolving electric vehicle (EV) charging and battery energy storage markets, which are undergoing a structural transformation towards a more decentralized, carbon-neutral, and electrified energy system. The rapid growth of EVs is projected to require approximately 3.5 million public charging points in Europe by 2030, while battery storage deployment in Europe reached record annual additions of over 27 GWh ¹ in 2025, with total installed capacity expected to approach 400 GWh ² over the next decade. The company's solutions are designed to address the mismatch between available grid capacity and increasing power demand by enabling local energy storage and high-power delivery independent of immediate grid availability.

ADSE is an emerging growth company with a history of losses and currently generates negative cash flow from operations, creating uncertainty regarding its ability to continue as a going concern. The company's financial performance has been volatile, with revenues declining significantly in 2025 to approximately EUR 31.6 million ³ from approximately EUR 110.0 million ⁴ in 2024, primarily due to the insolvency of a key customer and a strategic transition towards new business lines that have not yet generated substantial revenue. The company reported net losses of approximately EUR 55 million ⁵ in 2025, compared to approximately EUR 98 million ⁶ in 2024, and had an accumulated deficit of EUR 344.3 million ⁷ as of December 31, 2025.

ADSE's core business model involves the development and provision of battery-based energy infrastructure solutions, including battery-buffered ultra-fast charging solutions and battery energy storage systems (BESS). Revenue is primarily generated through the sale of these products under hardware sales contracts, complemented by digital energy management platforms and lifecycle services, such as monitoring, maintenance, and service agreements, which contribute to recurring revenue streams. The company is also expanding into an Own & Operate (O&O) model, where it directly participates in the operation of infrastructure assets and related revenue streams, including charging fees, energy trading, and digital advertising. Additionally, ADSE is developing large-scale battery storage projects, including one with a planned capacity of approximately 1 GW ⁸ and up to 4 GWh ⁹.

The company's product and service offerings are categorized into "Charging," "Service," and "Commercial and industrial." In 2025, "Charging" revenue was EUR 18,740 thousand ¹⁰, "Service" revenue was EUR 10,277 thousand ¹¹, "Commercial and industrial" revenue was EUR 2,190 thousand ¹², and "Other" revenue was EUR 352 thousand ¹³, totaling EUR 31,559 thousand ¹⁴. Geographically, in 2025, Germany accounted for EUR 15,654 thousand ¹⁵ in revenue, Rest of Europe for EUR 12,939 thousand ¹⁶, United States of America for EUR 2,454 thousand ¹⁷, and Rest of the world for EUR 512 thousand ¹⁸.

For the fiscal year ended December 31, 2025, total revenue decreased by EUR 78,454 thousand ¹⁹, or 71% ²⁰, to EUR 31,559 thousand ²¹ from EUR 110,013 thousand ²² in 2024. Cost of sales decreased by EUR 42,743 thousand ²³, or 47% ²⁴, to EUR -47,842 thousand ²⁵ in 2025 from EUR -90,585 thousand ²⁶ in 2024. Gross profit declined by EUR 35,710 thousand ²⁷, or 184% ²⁸, from a profit of EUR 19,427 thousand ²⁹ in 2024 to a negative of EUR -16,283 thousand ³⁰ in 2025. This decline was primarily due to lower sales volumes and inventory write-downs of EUR 13.2 million ³¹ related to raw materials and finished goods. Operating result was EUR -56,694 thousand ³² in 2025, a significant deterioration from EUR -8,609 thousand ³³ in 2024. Net finance result improved from negative EUR 88,858 thousand ³⁴ in 2024 to EUR 1,246 thousand ³⁵ in 2025, driven by a gain of EUR 40.5 million ³⁶ from the remeasurement of warrant liabilities and foreign currency gains of EUR 19.8 million ³⁷. The result for the period was a loss of EUR -55,190 thousand ³⁸ in 2025, an improvement from a loss of EUR -97,958 thousand ³⁹ in 2024. Diluted and basic EPS were both EUR -0.98 ⁴⁰ in 2025, compared to EUR -1.91 ⁴¹ in 2024. Cash and cash equivalents as of December 31, 2025, were EUR 6,987 thousand ⁴², down from EUR 22,858 thousand ⁴³ in 2024. Total current loans and borrowings were EUR 5,010 thousand ⁴⁴ as of December 31, 2025, compared to EUR 13,333 thousand ⁴⁵ as of December 31, 2024.

Year-over-year, revenue from "Charging" decreased by EUR 83,793 thousand ⁴⁶, or 82% ⁴⁷, in 2025 compared to 2024. Conversely, "Service" revenue increased by EUR 4,674 thousand ⁴⁸, or 83% ⁴⁹, and "Commercial and industrial" revenue increased by EUR 513 thousand ⁵⁰, or 31% ⁵¹. Geographically, revenue in Europe decreased by EUR 75,285 thousand ⁵², or 72% ⁵³, and in North America by EUR 3,169 thousand ⁵⁴, or 56% ⁵⁵. The gross profit margin contracted significantly due to lower sales and inventory write-downs. Research and development expenses decreased by EUR 0.4 million ⁵⁶, or 5% ⁵⁷, to EUR 8.5 million ⁵⁸ in 2025. Selling and general administrative expenses increased by EUR 1.2 million ⁵⁹, or 4% ⁶⁰, to EUR 32,797 thousand ⁶¹ in 2025.

During 2025, ADSE issued convertible notes with a total principal amount of USD 53.8 million ⁶², which were settled prior to maturity on November 19, 2025. A total principal amount of USD 29 million ⁶³ and interest of USD 1.8 million ⁶⁴ were converted into equity, resulting in an equity increase of EUR 26.8 million ⁶⁵. The remaining outstanding principal, interest, and prepayment premium were settled in cash, leading to a cash outflow of $27.9 million ⁶⁶. Subsequent to December 31, 2025, the company undertook further financing and capital structure transactions, including amending and extending certain shareholder loan facilities. On May 14, 2026, a secured promissory note to Lucerne Capital Management LP was amended to increase the principal commitment to USD 25 million ⁶⁷ and extend the maturity date to July 31, 2027 ⁶⁸. The Svelland promissory note was also amended to increase the total commitment to EUR 32.5 million ⁶⁹ and extend its maturity to July 31, 2027 ⁷⁰. In April 2026, the company repriced certain warrants held by Lucerne-affiliated entities, which were then exercised for 5,172,045 ⁷¹ Ordinary Shares, generating gross cash proceeds of approximately $5.2 million ⁷². In May 2026, subscription agreements resulted in the issuance of 6,324,000 ⁷³ Ordinary Shares and gross cash proceeds of approximately $6.3 million ⁷⁴.

ADSE expects 2026 to be a challenging year due to market uncertainties stemming from geopolitical conflicts, supply chain disruptions, and trade barriers. The company anticipates that the expansion of its business model, particularly into new business lines, will require a start-up phase, with an increase in revenue projected to begin in late 2026 and continue into 2027.

The company's growth strategy is heavily focused on the development and scaling of additional business lines, including service and maintenance offerings, software-enabled energy management solutions, Own & Operate (O&O) activities, and the large-scale utility BESS project (SKM Project) with approximately 1 GW ⁷⁵ and 4 GWh ⁷⁶ capacity. These initiatives are being developed in parallel, with an emphasis on establishing scalable operating structures and generating incremental revenue contributions over time. The SKM Project is a key priority, with the company aiming to achieve ready-to-build (RTB) status within the planned timeframe by finalizing construction permitting and grid connection arrangements. The company is also engaging with suppliers and engineering partners to prepare for the construction phase.

Operationally, ADSE is increasing its focus on service and lifecycle offerings for its installed base of charging and battery storage systems. This includes expanding long-term service and maintenance contracts, strengthening its service organization, and increasing the number of systems under active service agreements. Digital service capabilities, such as monitoring, diagnostics, and energy management solutions, are being further developed to enhance system performance and generate recurring service revenues. The rollout of the O&O model involves securing suitable sites, deploying charging systems, and establishing operational capabilities for asset management, with over 150 ⁷⁷ sites already secured at exclusive retailer locations in Germany.

The company is implementing a structured funding approach for the SKM Project, which combines external equity participation and long-term project financing. Following the achievement of RTB status, ADSE plans to pursue the sale of a minority stake in the project to a third-party equity partner to secure additional capital and share project-related risks. The company also continues its geographic expansion, particularly in Europe and North America, by strengthening local sales and service capabilities and adapting its offerings to local regulatory and market requirements.

ADSE's capital allocation plans include continued investment in research and development activities to advance its technology and product roadmap, with R&D expenses expected to increase on an absolute basis. The company may also extend its warehouse facility in the United States into a production facility, which would contribute to increased depreciation and amortization expenses over time. Selling, general, and administrative expenses are expected to remain at the fiscal year 2025 level in fiscal year 2026.

ADSE faces several material risks, including its status as an emerging growth company with a history of losses and negative cash flow, creating substantial doubt about its ability to continue as a going concern. The company's revenues declined significantly in 2025, primarily due to decreased sales of battery-buffered charging systems and battery storage solutions and a strategic transition to new business lines that have not yet generated sufficient revenue. There is uncertainty regarding the company's ability to sell existing inventory at anticipated prices or within expected timeframes, and its ability to generate recurring revenues from service contracts and software offerings is uncertain and depends on customer adoption and retention. The expansion into an Own & Operate model exposes the company to increased capital requirements, utilization risk, and operational complexity. The successful development of the large-scale battery project is crucial for future revenues, but it may fail to reach ready-to-build (RTB) status due to challenges in site selection, land rights, construction permitting, and grid connection. The company may also be unable to successfully sell a stake in this project or secure long-term financing.

The EV charging and battery energy storage markets are evolving and uncertain, with rapid technological and regulatory changes requiring continuous product development and intellectual property expansion. ADSE faces significant and increasing competition across all business lines, including from specialized platform providers, equipment manufacturers, utilities, and new entrants, many of whom have greater resources. Changes to fuel economy standards or the success of alternative fuels could negatively impact the EV market and demand for ADSE's products. The company's growth is highly dependent on the continued rapid adoption of EVs, which is subject to various factors including consumer perceptions, government incentives, and economic conditions. Similarly, changes to battery energy storage standards or the success of alternative energy storage technologies could negatively impact demand for its BESS products. The company has a concentration of sales with several key customers, with approximately 77% ⁷⁸ of total revenue in 2025 generated by its ten largest customers, and four customers each accounting for approximately 10% ⁷⁹ of total revenue, making it vulnerable to adverse developments affecting these customers. ADSE relies on a limited number of suppliers for key components, increasing exposure to supply disruptions and cost increases. The company's products may contain defects or errors, which could result in liability, reputational harm, and other adverse effects. Furthermore, ADSE is subject to evolving environmental, cybersecurity, data protection, and ESG-related regulatory requirements, which may increase compliance costs and risks. The company has identified material weaknesses in its internal control over financial reporting, which could impair its ability to produce reliable financial statements.

Management's message to shareholders emphasizes the company's strategic transition from a primarily hardware-driven model to a more diversified business model with a growing focus on recurring revenues and integrated energy infrastructure solutions. They acknowledge the significant financial and operational challenges faced in 2025, including a substantial decline in revenues and recurring losses, primarily due to the insolvency of a key customer and the ongoing strategic shift. Despite these challenges, management believes its current strategy will support profitable growth and is actively working towards profitability. They expect an increasing contribution from recurring revenue streams and a gradual transition toward a more stable and diversified revenue base over time, with revenue growth starting late 2026 into 2027. The three strategic priorities emphasized for the period ahead are: restoring growth in core product sales by expanding the customer base and strengthening the commercial organization; developing and scaling additional business lines, including service and maintenance offerings, software-enabled energy management solutions, Own & Operate (O&O) activities, and the large-scale utility BESS project (SKM Project); and advancing the SKM Project to ready-to-build (RTB) status, including securing financing and partnerships.
