For the fiscal year ended December 31, 2025, ADSE reported total revenue of EUR 31.559 million ¹, a significant decrease of 71% ² from EUR 110.013 million ³ in 2024. The company incurred a gross loss of EUR 16.283 million ⁴ in 2025, compared to a gross profit of EUR 19.427 million ⁵ in 2024, representing a 184% ⁶ decline. Operating result was a loss of EUR 56.694 million ⁷ in 2025, worsening from a loss of EUR 8.609 million ⁸ in 2024. The net loss for the period was EUR 55.190 million ⁹, an improvement from a net loss of EUR 97.958 million ¹⁰ in 2024. Diluted EPS was -0.98 EUR ¹¹ in 2025, compared to -1.91 EUR ¹² in 2024. Cash and cash equivalents stood at EUR 6.987 million ¹³ as of December 31, 2025, down from EUR 22.858 million ¹⁴ in 2024. Total current loans and borrowings were EUR 5.010 million ¹⁵ in 2025, a decrease from EUR 13.333 million ¹⁶ in 2024.

Year-over-year, revenue from the "Charging" segment decreased by EUR 83.793 million ¹⁷, or 82% ¹⁸, to EUR 18.740 million ¹⁹ in 2025 from EUR 102.533 million ²⁰ in 2024. Conversely, "Service" revenue increased by EUR 4.674 million ²¹, or 83% ²², reaching EUR 10.277 million ²³ in 2025 from EUR 5.603 million ²⁴ in 2024. "Commercial and industrial" revenue grew by EUR 0.513 million ²⁵, or 31% ²⁶, to EUR 2.190 million ²⁷ in 2025 from EUR 1.677 million ²⁸ in 2024. Geographically, revenue in Europe decreased by EUR 75.285 million ²⁹, or 72% ³⁰, to EUR 29.105 million ³¹ in 2025, while North America revenue decreased by EUR 3.169 million ³², or 56% ³³, to EUR 2.454 million ³⁴. Gross profit declined significantly due to lower sales volumes and inventory write-downs of EUR 13.2 million ³⁵ related to raw materials and finished goods. Research and development expenses decreased by EUR 0.4 million ³⁶, or 5% ³⁷, to EUR 8.488 million ³⁸ in 2025. Selling and general administrative expenses increased by EUR 1.2 million ³⁹, or 4% ⁴⁰, to EUR 32.797 million ⁴¹ in 2025, mainly due to increased legal and consulting fees.

During 2025, ADSE experienced a significant decline in revenue in its EV-charging hardware business, primarily due to reduced demand following the insolvency of a key customer. This contributed to increased inventory levels and subsequent write-downs. The company also issued convertible notes totaling USD 53.8 million ⁴² on May 1, 2025, which were settled by November 19, 2025, with USD 29 million ⁴³ converted into equity and the remainder repaid in cash, resulting in a cash outflow of $27.9 million ⁴⁴. Post-December 31, 2025, ADSE undertook further financing activities, including amending and extending shareholder loan facilities, increasing a secured promissory note to USD 25 million ⁴⁵ with a maturity date of July 31, 2027 ⁴⁶, and increasing another promissory note to EUR 32.5 million ⁴⁷ with the same maturity date. Additionally, in April 2026, certain warrants were repriced to an exercise price of $1.00 per share ⁴⁸ and exercised for 5,172,045 Ordinary Shares ⁴⁹, generating gross cash proceeds of approximately $5.2 million ⁵⁰. In May 2026, the company issued 6,324,000 Ordinary Shares ⁵¹ through subscription agreements, yielding gross cash proceeds of approximately $6.3 million ⁵².

ADSE anticipates 2026 to be a challenging year due to market uncertainties stemming from geopolitical conflicts, supply chain disruptions, and trade barriers, which could impact sales growth and expansion efforts in the United States. The company expects an increase in revenue starting late 2026 into 2027 as its expanded business model progresses through its start-up phase.

A major growth area for ADSE is 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 and 4 GWh. These initiatives are being developed concurrently, with a focus on establishing scalable operating structures and generating incremental revenue contributions over time. The O&O model, which involves deploying and operating charging infrastructure at selected German locations, is expected to generate recurring revenues from ultra-fast charging, energy trading, and advertising as the installed base grows.

Another significant growth vector is the advancement of the SKM Project to ready-to-build (RTB) status within the planned timeframe. This involves finalizing construction permitting, establishing binding grid connection arrangements, and negotiating technical and commercial terms with the transmission system operator. The company is also engaging with suppliers and engineering partners to prepare for the construction phase. The SKM Project is designed as an integrated energy system combining large-scale battery storage with photovoltaic generation, aiming to enhance economic performance through optimized energy sourcing and revenue stacking across multiple markets. ADSE expects to own and operate up to 49% ⁵³ of this project, which is planned for operational go-live in the second half of 2029 ⁵⁴ and is expected to generate long-term recurring revenues and financial strength.

Operationally, ADSE expects its gross profit to increase on an absolute basis and gross margin to improve over time as it expands revenue and optimizes operations and its supply chain. However, in the short term, gross margin may experience variability due to new product introductions and growth in Europe and the United States. Selling, general, and administrative (SG&A) expenses are expected to remain at the fiscal year 2025 level in fiscal year 2026. Research and development expenses are anticipated to increase on an absolute basis and potentially as a percentage of total revenue as the company continues to invest in its technology and product roadmap. Depreciation and amortization expenses are also expected to increase as ADSE develops new products and may convert its U.S. warehouse facility into a production facility.

ADSE's capital allocation plans include securing additional funding for its operations and large-scale projects. The company is implementing a structured funding approach for the SKM Project, combining external equity participation and long-term project financing. Following 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 risks. Recent financing activities include the amendment and extension of shareholder loan facilities, increasing a secured promissory note to USD 25 million ⁵⁵ and another to EUR 32.5 million ⁵⁶, both maturing on July 31, 2027 ⁵⁷. Additionally, the company received approximately $5.2 million ⁵⁸ from warrant exercises and approximately $6.3 million ⁵⁹ from the issuance of Ordinary Shares through subscription agreements in April and May 2026, respectively, with net proceeds intended for general corporate purposes, including working capital and capital expenditures.

ADSE faces several material risks, including its status as an emerging growth company with a history of losses and negative cash flow from operations, creating uncertainty about its ability to continue as a going concern. The company's future viability depends on reversing a significant revenue decline in 2025, from approximately EUR 110 million ⁶⁰ in 2024 to approximately EUR 32 million ⁶¹ in 2025, driven by decreased sales of battery-buffered charging systems and battery storage solutions and a strategic transition to new business lines. There is a risk that existing inventory of charging systems may not be sold at anticipated prices or within expected timeframes, potentially leading to material write-downs or impairment charges. The ability to generate recurring revenues from service contracts and software offerings is uncertain and depends on customer adoption, retention, and service performance. The expansion into an Own & Operate model exposes ADSE to increased capital requirements, utilization risk, and operational complexity, with no assurance that it will generate sufficient revenues to offset declines in product sales. 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. Furthermore, the company may be unable to successfully sell a stake in this project or secure long-term financing, which would require significant capital expenditure. ADSE relies on a limited number of suppliers, and increases in material costs or reduced availability could adversely affect margins and operations. The company also faces significant and increasing competition across all business lines, including from established players and new entrants with greater resources. Changes to fuel economy standards or the success of alternative fuels could negatively impact the EV market, while changes to battery energy storage standards or alternative energy storage technologies could reduce demand for ADSE's products. The company is subject to evolving environmental, cybersecurity, data protection, and ESG-related regulatory requirements, which may increase compliance costs and risks, and the reduction or elimination of government incentives could adversely affect its business. ADSE has identified material weaknesses in its internal control over financial reporting, which could impair its ability to produce reliable financial statements and lead to significant additional costs and management time.

Management's message to shareholders emphasizes a 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, including recurring losses and negative cash flows from operations, and are working towards profitability. Management believes its current strategy will support profitable growth, but there is no assurance of achieving positive EBITDA or profitability within any particular timeframe. The company expects 2026 to be a challenging year due to market uncertainties, but anticipates 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. Key strategic priorities include restoring growth in core product sales by expanding the customer base and strengthening the commercial organization, developing and scaling additional business lines such as service and maintenance offerings, software-enabled energy management solutions, and Own & Operate (O&O) activities, and advancing the large-scale utility BESS project (SKM Project) to ready-to-build (RTB) status and securing its financing.
